DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) The sealant filling device of the present invention is provided to solve the problems that the sealant volume and consumption of each sealant filing device are unbalance to make some sealant remained during synchronous pouring sealant process. The sealant filling device comprises a sealant board 1 and a plurality of injectors 2 installed on the sealant board 1. The sealant board 1 comprises a base 10 and a sealing cover 12 which defines a plurality of filing holes 120. The plurality of injectors 2 are clamped on the base 10. A feeding hole 200 of each injector 2 is arranged opposite to the sealing holes 120. The sealant can be poured into the injector 2 from the sealing holes 120 via the feeding hole 200. A spring 3 is arranged between a top of the plurality of injector 2 and the sealing cover 12. While a volume of the sealant reaches a preset value, the spring 3 is controlled to move and seal off the sealing hole 120 to stop sealing. Preferably, the spring 3 can be mounted on a bottom of the sealing cover 12 of the plurality of injector 2, so the sealant would not be flowed out from the injector to seal off the feeding hole 200 with the spring 3 closely contacts with the sealing cover 12.

(7) The sealing cover 12 of the sealant board 1 is located on the base 10. The base 10 comprises a plurality of clampers for clamping bottoms of the injectors 2. The injectors 2 can be clamped to stand up. A top of the each of the injector 2 resists the sealing cover, and the top of each of the injector 2 opens a feeding hole 200 which is opposite to the sealing holes 120. The injector 2 comprises a top cover 20, a packaging barrel 22 and an injector head 24. A plurality of feeding holes 200 are defined on the top cover 20. The injector head 24 is mounted at a bottom of the packaging barrel 22. The sealant can be poured into the packaging barrel 22 from the feeding hole 200 and be poured out from the injector head 24. The sealant can be simultaneously poured out from the plurality of injectors 2.

(8) Referring to FIG. 2, in the first embodiment a weight sensor 4 is arranged on the bottom of the injector 2 for measuring a sealant weight of the injector 2 and determining whether the sealant weight reaches a preset weight or not. If the sealant weight reaches the preset weight, then the weight sensor 4 sends a feedback signal to the controller IC. Referring to FIG. 3, the injector 2 comprises a controller IC 2a and a motor 2b, the controller IC 2a is electrically connected with the weight sensor 4 and the motor 2b, the motor 2b is also electrically connected with the spring 3, the controller IC 2a is provided for receiving the feedback signal from the weight sensor 4 and driving the spring 3 to seal off the sealing hole 120 of the sealing cover 12. The spring 3 is driven by the motor 3.

(9) Referring to FIGS. 3-5, in the second embodiment, a height sensor 5 is located at the both sides of the injector 2 for measuring whether a height of the sealant reaches a highest preset value or not. The height sensor 5 comprises a signal generator 50 and a signal receiver 52 which are located in a same horizontal line, while the height of the injected sealant reaches the highest preset value, the signal receiver 52 can not receive the signal from the signal generator 50, and the signal receiver 52 will send a broken signal to the controller IC 2a to drive the spring 3 to seal off the sealing hole by controlling the motor. The signal generator 50 and the signal receiver 52 are separated placed on the both sides of the injector 2, a distance between the signal generator 50 and the injector 2 is equal to that of between the signal receiver 52 and the injector 2. A signal source of the signal generator 50 is an infrared ray. A distance between the signal generator 50 and the edge of the injector 2 is 1.5-2 cm.

(10) A volume of the sealant can be figured out with the weight or the height of the sealant in the package barrel 22. When the sealant weight reaches the preset value, then the weight sensor 4 will send the feedback signal to the controller IC 2a to drive the spring 3 to seal off the sealing hole 120 of the sealing cover 12. Similarly, when the sealant height reaches the highest preset value, the signal receiver 52 can not receive the signal from the signal generator 50, and the signal receiver 52 will send a broken signal to the controller IC 2a to drive the spring 3 to seal off the sealing hole 120 by controlling the motor. Accordingly, the spring 3 can be controlled to move according to compared results between the sealant height and the highest preset value or the sealant weight and the preset value.

(11) The sealant volume in each injector can be separated distributed. The sealant volume can be controlled with the weight sensor and the height sensor so as to precisely distribute the volume of the sealant. As a result, the filling precision and the degree of automation will be improved and the remaining and producing of the sealant will be reduced with automatically controlling the filling process.
