[0060] The material discharging module 430 includes a material discharging bracket 431, a plurality of film pickers 432 arranged on the material discharging bracket 431, and a material discharging movement mechanism connected to drive the material discharging bracket 431 to move, wherein the plurality of film pickers 432 are divided into four groups, wherein two groups of film pickers 432 are located at the front side of the material discharging bracket 431 (towards the coating part 300), and the two groups of film pickers 432 located at the front side of the material discharging bracket 431 are arranged in parallel on the left and right and correspond to the two coating channels respectively, and the other two groups of film pickers 432 are located at the rear side of the material discharging bracket 431 (backwards from the coating part 300), and the two groups of film pickers 432 located at the rear side of the material discharging bracket 431 are arranged in parallel on the left and right and correspond to the two coating channels respectively.

[0061] During material discharge, after the film cutting module 350 cuts off the edge sealing on the other side of the two groups of upper protective films 372 and the lower protective film 371 from the middle to form two injection molded film parts, the material discharge movement mechanism drives the film picker 432 to descend, and the two groups of film pickers 432 located on the left side of the material discharge bracket 431 respectively grab the front and back sides of one of the injection molded film parts, and the two groups of film pickers 432 located on the right side of the material discharge bracket 431 respectively grab the front and back sides of the other injection molded film parts, and then the edge sealing assembly 340 releases the edge sealing on the other side of the two injection molded film parts, and the material discharge movement mechanism drives the film picker 432 to continue to descend to place the two injection molded film parts into the packaging box 450, and then the film picker 432 releases the two injection molded film parts, and then the material discharge movement mechanism drives the film picker 432 to rise and reset.

[0062] Each set of film takers 432 includes at least two film takers 432 to correspondingly grab the two corners on the side of the injection molded film. The material discharge movement mechanism includes a material discharge driver 433, and the material discharge bracket 431 is arranged on the material discharge driver 433 and driven by the material discharge driver 433 to move up and down.

[0064] When the needle driver 434 drives the film removal needle 433 to extend out of the through hole, the film removal needle 433 is inserted into the injection molded film component. Since the film removal needle 433 tilts downward toward the outside of the discharge bracket 431 together with the second fixing portion 4352, the needle tip distance of the film removal needle 433 located on the front and rear sides of the discharge bracket 431 is greater than the needle hole distance located on the front and rear sides of the injection molded film component. Therefore, the injection molded film component will be suspended on the film removal needles 433 on the front and rear sides; when the needle driver 434 drives the film removal needle 433 to retract into the through hole, the film removal needle 433 is pulled out of the injection molded film component, and the injection molded film component loses the suspension of the film removal needles 433 on the front and rear sides and falls.

[0068] During loading, pairs of injection molded parts are placed on the conveyor belt module 110 manually, or pairs of injection molded parts are transferred from the injection molding machine to the conveyor belt module 110 by a transfer robot; then the positioning module 120 positions the pairs of injection molded parts on the conveyor belt module 110, and after positioning, the conveyor belt module 110 drives the pairs of injection molded parts to continue to be transported to the dewatering port module 130, and the dewatering port module 130 removes the dewatering port bracket connected between the pairs of injection molded parts, and then the conveyor belt module 110 drives the pairs of injection molded parts to continue to be transported to the grabbing position.

[0069] In this embodiment, the drain module 130 is an ultrasonic drain device.

[0070] Preferably, the sorting part 200 also includes a waste removal gripper arranged next to the two pickers 201, and the waste removal gripper is used to grab the sprue bracket located between the pair of injection molded parts when the two pickers 201 grab the pairs of injection molded parts at the grabbing position of the conveyor belt module 110, and discard the grabbed sprue bracket when the two pickers 201 leave the grabbing position of the conveyor belt module 110.

[0071] Of course, the nozzle support may also fall naturally as the conveyor belt module 110 is conveyed.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention rather than to limit them. Although the embodiments of the present invention have been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the embodiments of the present invention can still be modified or replaced by equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
