[0012] A system for feeding a diaphragm, as shown in FIG. 1, comprises a diaphragm separating device 100 and a visual device 200. The diaphragm separating device 100 is adapted to separate a single diaphragm 10 from at least one stack of diaphragms 10. The visual device 200 is adapted to identify the separated single diaphragm 10 and the position of the separated single diaphragm 10.

[0013] As shown in FIGS. 2-3, the diaphragm separating device 100 includes a diaphragm bin 110 and a diaphragm sweeping mechanism 120. At least one stack of diaphragms 10 is loaded in the diaphragm bin 110. In an embodiment, an interior bottom surface of the diaphragm bin 110 is flat, so that a stack of or stacks of diaphragms 10 may be placed and stacked on the interior bottom surface of the diaphragm bin 110. The diaphragm sweeping mechanism 120 is adapted to sweep a top of at least one stack of diaphragms 10, in order to separate the single diaphragm 10 from the top of at least one stack of diaphragms 10 and arrange the separated diaphragm 10 at a new position, so that the separated diaphragm 10 may be picked up by the robot 300.

[0014] In the shown embodiment, the diaphragm separating device 100 includes a plurality of diaphragm sweeping mechanisms 120. As shown in FIGS. 2-3, each diaphragm sweeping mechanism 120 includes a support frame 121, 122, 123 and a sweeping brush 124. The support frame 121, 122, 123 is adapted to move back-and-forth in a straight line, for example, move reciprocally in a left-right direction in FIG. 3. The sweeping brush 124 is installed on the support frame 121, 122, 123 and adapted to move back-and-forth along with the support frame 121, 122, 123. When moving back-and-forth along with the support frame 121, 122, 123, the sweeping brush 124 sweeps the top of at least one stack of diaphragms 10 in order to separate the single diaphragm 10 from the top of at least one stack of diaphragms 10.

[0015] As shown in FIGS. 2-3, a pair of sliding rails 130, 130 are arranged on both sides of the diaphragm bin 110 and extend in a straight line parallel to the axis of the diaphragm bin 110. The support frame 121, 122, 123 is slidably installed on a pair of sliding rails 130, 130, so as to move reciprocally along a pair of sliding rails 130, 130.

[0016] As shown in FIGS. 2-3, the support frame 121, 122, 123 includes a pair of support vertical arms 121, 121 and a support transverse arm 122. Lower portions of a pair of support vertical arms 121, 121 are slidably installed on the pair of sliding rails 130, 130, respectively. The support transverse arm 122 is connected at a pair of opposite ends thereof to a pair of upper portions of a pair of support vertical arms 121, 121. The sweeping brush 124 is mounted on the support transverse arm 122.

[0017] As shown in FIGS. 2-3, the support frame 121, 122, 123 further includes a pair of brush connecting parts 123, 123 installed on the support transverse arm 122. The pair of brush connecting parts 123, 123 is adapted to be connected to a pair of ends of the sweeping brush 124, such that the sweeping brush 124 is installed in a suspended manner on the support transverse arm 122.

[0018] In an embodiment, the support frame 121, 122, 123 is configured to be height-adjustable so that the sweeping brush 124 installed on the support frame 121, 122, 123 is height-adjustable, causing height of the sweeping brush 124 matched with the diaphragm 10 to be separated. For example, if the diaphragm 10 to be separated has a thinner thickness, a height of the sweeping brush 124 is lowered; if the diaphragm 10 to be separated has a thicker thickness, the height of the sweeping brush 124 is increased. In this way, the height of the sweeping brush 124 may be matched with the diaphragm 10 to be separated, improving efficiency of separating diaphragms 10.

[0019] As shown in FIGS. 2-3, the system further includes a linear actuator 140 adapted to drive a corresponding set of diaphragm sweeping mechanism 120 to move back-and-forth in a straight line. In the shown embodiment, the system includes a pair of linear actuators 140. Each linear actuator 140 is connected to one of two support vertical arms 121, 121 of the corresponding set of diaphragm sweeping mechanism 120, in order to drive the support vertical arms 121, 121 to move back-and-forth along the sliding rails 130, 130. In various embodiments, the linear actuator 140 is a lead screw drive mechanism, an electrically controlled hydraulic cylinder, or an electrically controlled cylinder.

[0020] As shown in FIGS. 2-3, the diaphragm separating device 100 has two sets of diaphragm sweeping mechanisms 120, 120, a first set of diaphragm sweeping mechanism 120 being disposed at a first side of the diaphragm bin 110, and a second set of diaphragm sweeping mechanism 120 being disposed at an opposite second side of the diaphragm bin 110. The system has two linear actuators 140, 140, a first linear actuator 140 being disposed at the first side of the diaphragm bin 110 for driving the first set of diaphragm sweeping mechanism 120, and a second linear actuator 140 being disposed at the second side of the diaphragm bin 110 for driving the second set of diaphragm sweeping mechanism 120.

[0021] As shown in FIG. 2, the system for feeding a diaphragm further includes a mounting base 101, on which the diaphragm bin 110 and the pair of sliding rails 130, 130 are mounted. The mounting base 101 has a pair of upright support walls 102, 102. The diaphragm bin 110 is mounted on tops of the pair of upright support walls 102, 102, and the pair of sliding rails 130, 130 is mounted outside the pair of upright support walls 102, 102, respectively.
