DETAILED DESCRIPTION OF EMBODIMENTS

[0021] The present disclosure will be described as follows in combination with embodiments and attached drawings:

[0022] The present device primarily aims at an issue that in a silicon wafer cutting device in a silicon wafer cutting process, a coolant impacts a primary roller and diamond wire rotated at a high speed by a motor in cutting process to result in some of the coolant splashed onto a feed stage and a clamping mushroom head and splashed coolant after evaporated will leave contained silicon micro powders onto the structures of the feed stage and the clamping mushroom head such that precisely cleaning is needed.

[0023] In an embodiment of the present disclosure, with reference to FIG. 1, an under-wire spray cleaning device for a wire cutting machine comprises: a trough body 1 and a spray assembly connected to the trough body 1. The spray assembly comprises first nozzles 3 disposed on an inside of the trough body 1 and second nozzles 6 disposed on an outside of the trough body 1. During a cleaning process, the entire trough body is placed in an engaging slot of a nozzle pipe device for cleaning, and then is spray-cleaned by the first nozzles 3 and the second nozzles 6 by controlling a water flow into the spray assembly. The first nozzles 3 clean important parts such as a feed machine and a clamping mushroom head, and the second nozzles 6 perform a spraying process to a sheave on an outside of the trough body. Compared to a conventional technology, after an original nozzle pipe device is detached, the engaging slot of the present cleaning device is directly installed in the engaging slot of the nozzle pipe device such that installation is more convenient and faster. Also, after the structure is washed, the engaging slot can be conveniently detached, and the nozzle pipe can be re-installed to proceed with later operations through the present device. In the present embodiment, the spray assembly can be injected with reverse osmosis (RO) water.

[0024] With reference to FIG. 1, in the present embodiment, the trough body 1 used is a rectangular trough body structure having an aperture defined in a top of the rectangular trough body structure. For convenience of supplying water to the spray assembly of the inside of the trough body 1, an aperture can also be defined in a sidewall of the trough body 1 at an inlet side, or an inlet hole is defined in the sidewall of the trough body 1 for a hose to pass through the inlet hole. The spray assembly is disposed on two sidewalls on the inside of the trough body 1. Also, a drainage outlet 4 is disposed in a bottom portion of the trough body 1 for discharging sprayed water.

[0025] In the present embodiment, the spray assembly disposed on the inside of the trough body 1 comprises: first nozzle pipes 2 and the first nozzles 3. The first nozzle pipes 2 are symmetrically disposed along an inner sidewall of the trough body 1. At least two of the first nozzle pipes 2 are disposed on the inner sidewall of each side of the trough body 1, and the same first nozzle pipes 2 are distributed on the inner sidewall of each side of the trough body 1. The first nozzles 3 are disposed on the first nozzle pipes 2 at intervals evenly.

[0026] In the present embodiment as shown in FIG. 1, the first nozzles 3 and the inner sidewall of the trough body 1 form a certain included angle. A disposing angle of the first nozzles 3 is adjusted according to locations of the feed stage and the clamping mushroom head to be cleaned such that water sprayed out from the first nozzles 3 can be targeted at the feed stage and the clamping mushroom head for washing and cleaning. Two first nozzle pipes 2 are disposed abreast on the inner sidewall of each side of the trough body 1 to make a spraying range broader. Also, the intervals among the first nozzles 3 on the two first nozzle pipes 2 can be the same or different. The two first nozzle pipes 2 are connected by a pipeline. In particular, in the present embodiment, the first nozzle pipes 2 below a height are connected to an external water pipe by a connector 8 for supplying water, and the first nozzle pipes 2 above the height are supplied with water by the first nozzle pipes 2 below the height through a pipeline. It is conceivable that a sequence of the first nozzle pipes connected to the connector 8 can be adjusted.

[0027] In the present embodiment, the first nozzle pipes 2 are connected to the inner sidewall of the trough body 1 by a press-fit fastener 7. The press-fit fastener 7 can employ the structure as shown in FIG. 1, specifically including a supporting bracket 71 and a collar element 72. The supporting bracket 71 is disposed on the trough body 1 and fastens the first nozzle pipes 2 and the press-fit fastener 7 by the collar element 72. The collar element 72 only performs a fastening function. Correspondingly, a hole is formed in a matching portion between the collar element 72 and the supporting bracket 71 to allow the first nozzle pipes 2 to pass through the hole. The first nozzle pipes 2 disposed on two sides of the inside of the trough body 1 can be connected to the external water pipe by the same or different connectors on adjacent sidewalls of the trough body 1. In the present embodiment, the first nozzle pipes 2 on two sidewalls of the inside of the trough body 1 are converged to the common connector 8 and then connected to the external water pipe, which facilitates controlling water flow in the nozzle pipe. Disposing the structures of the nozzle pipe and the nozzle achieves adjustment of water in the nozzle pipe, which increases a water pressure, facilitates washing various impurities to maintain cleanliness of the machine and guarantee stability of cutting quality.

[0028] The spray assembly disposed on the outside of the trough body 1 comprises: second nozzle pipes 5 and the second nozzles 6. The second nozzle pipes 5 are symmetrically disposed on an outer sidewall of the trough body 1. Namely, a second nozzle pipe 5 is disposed on the outer sidewall of each side of the trough body 1, the second nozzles 6 are disposed on the second nozzle pipes 5 at intervals.

[0029] In the present embodiment, the second nozzle pipes 5 disposed on the outer sidewall of the trough body 1 are disposed near the bottom portion of the trough body 1, the second nozzles 6 and the outer sidewall of the trough body 1 form a certain included angle to facilitate cleaning the sheave of the outside of the trough body.

[0030] In the present embodiment as shown in FIG. 1, a disposing angle of the second nozzles 6 is adjusted according to a location of the sheave to be cleaned such that water sprayed out from the second nozzles 6 can be targeted at the outer sheave for washing and cleaning. In the present embodiment, the second nozzle pipes 5 are also connected to the outer sidewall of the trough body 1 by the press-fit fastener 7. The second nozzle pipes 5 disposed on two sides of the outside of the trough body 1 can be converged to the same or different connectors 8 to be connected to the external water pipe. In the present embodiment, the second nozzle pipes 5 on two sidewalls of the outside of the trough body 1 are converged to the common connector 8 and then are connected to the external water pipe. The connector 8 connected to the second nozzle pipes 5 and the connector 8 connected to the first nozzle pipes 2 are disposed on the same side to facilitate controlling water flow in the nozzle pipe such that various impurities can be washed out effectively and the structure is more compact.

[0031] A working process of an embodiment of the present disclosure:

[0032] An original nozzle pipe device of the apparatus is detached, the entire trough body 1 of the present cleaning device is placed in the engaging slot of the nozzle pipe device and also communicates with the external water pipe at the connector 8. It is conceivable that a flow and pressure regulator valve can be disposed on the external water pipe. During installation, disposing angles of the first nozzles 3 and the second nozzles 6 are adjusted. A cleaning operation starts, the spray assembly of the trough body 1 is injected with water, a flow is adjusted to a maximum to clean important parts such as the feed stage, the clamping mushroom head, and the outer sheave. When cleaning is completed, the entire trough body is detached and replaced with the original nozzle pipe for a cutting operation.
