[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0037] The present invention provides a fully automatic film stacking machine, comprising a frame 100; a conveying mechanism 110 arranged on the frame 100; and the following components are arranged in sequence on the conveying path of the conveying mechanism 110: an appearance inspection mechanism 200, used to inspect whether a film is qualified; an automatic cutting mechanism 300, used to cut the film after inspection by the appearance inspection mechanism 200; a waste collection mechanism 400, used to collect films that have defects in appearance inspection and are cut by the automatic cutting mechanism 300; a transport mechanism 500, used to transport films that are qualified after being cut by the automatic cutting mechanism 300; and a stacking mechanism 600, used to collect qualified films on the transport mechanism 500.

[0038] When implementing it, Figure 1-5As shown, the stacking machine is provided with an appearance inspection mechanism 200, an automatic cutting mechanism 300, a waste collection mechanism 400, a conveying mechanism 500, and a stacking mechanism 600 in sequence according to the film conveying path. The working principle is that after the film is inspected by the appearance inspection mechanism 200, it will be automatically cut, and unqualified film will be collected into the waste collection mechanism 400, and qualified film will be conveyed by the conveying mechanism 500 to the stacking mechanism 600. Among them, the conveying mechanism 110 is composed of a number of rollers and a vacuum adsorption conveyor belt; the appearance inspection mechanism 200 is used to detect whether the product's black spots, pinholes, cracks, steel belt interfaces, etc. are qualified, and it includes a visual detector and a light shield arranged on the periphery of the visual inspection. The light shield is used to avoid the strong light glare from the light source located at the bottom of the glass during visual inspection. As a preferred solution, other light-blocking devices can also be used, such as sticking frosted paper on the luminous part of the glass that is not blocked by the film; the stacking mechanism 600 includes a number of stacking bins 611, and a movable slide is provided at the bottom of the stacking bin 611. When the film in a stacking bin is full as required, the movable slide can be used to move another stacking bin to the bottom of the conveying mechanism 500 to continue stacking the film. At this time, the staff can take the stacked film out of the stacking bin; Figure 1 As shown, a control box is also provided next to the stacking machine for controlling the coordination between various mechanisms, the cutting size of the membrane, the stacking quantity, etc. Its specific structure and control method are prior arts known to those skilled in the art and will not be elaborated herein.

[0039] As a preferred solution, Figure 3 As shown, a buffer mechanism 130 and a transition conveyor 140 are also provided at the feed of the stacking machine. The buffer mechanism 130 is a roller assembly. The film being conveyed bypasses the roller assembly, passes through the transition conveyor 140, and is finally conveyed to the conveyor 110 to perform a series of operations. The two sets of buffer mechanisms 130 can well maintain the tension balance of film conveying. When the equipment and the film fail or stop abnormally, it can play a short-term buffering role. Upper and lower limit sensors are also provided below the buffer mechanism 130. When the film exceeds the lower limit sensor during the conveying process, the motor drives the transition conveyor 140 to move, pulls up the hanging film to the upper limit sensor and stops, which prevents the film from wrinkling due to accidentally hanging on the ground.

[0040] As another preferred solution, Figure 5 As shown, the stacking machine is further provided with a static eliminator 150 on the frame 100 for eliminating static electricity on the membrane to improve the performance of the membrane.

[0041] The fully automatic film stacking machine provided by the present invention can automatically cut the films, and sort out defective films through the appearance inspection mechanism 200 for centralized collection. Qualified films can be stacked into a silo according to the required number of films and layers. The whole process is fully automated and does not require manual film stacking, which reduces the labor intensity of workers, improves work efficiency, and improves practicality, and has good application prospects.

[0042] Preferably, a pressure roller assembly 120 for pressing the membrane is further provided above the conveying mechanism 110 , and the pressure roller assembly 120 includes a pressure rod 121 hingedly connected to the frame 100 and a pressure roller 122 connected to the other end of the pressure rod 121 .

[0043] When implementing it, Figure 1 As shown, a pressure roller assembly 120 for pressing the membrane is arranged above the conveying mechanism 110. The pressure roller assembly 120 includes a pressure rod 121 hinged to the frame 100 and a pressure roller 122 connected to the other end of the pressure rod 121. The pressure roller assembly 120 prevents the membrane from wrinkling during the conveying process and affecting the quality of the membrane.

[0044] Preferably, the automatic cutting mechanism 300 comprises a rolling knife device 310 for cutting the film, a driving cylinder 320 for driving the rolling knife device 310 and an adjusting device 330 for adjusting the cutting depth.

[0045] When implementing it, Figure 3 As shown, the automatic cutting mechanism 300 includes a rolling knife device 310 for cutting the film, a driving cylinder 320 for driving the rolling knife device 310, and an adjusting device 330 for adjusting the cutting depth. It should be understood that the cutting method can also be other methods, such as laser cutting, etc., which are all within the scope known to those skilled in the art.

[0046] Preferably, the transport mechanism 500 includes a guide rail assembly 510 mounted on the frame 100, a suction cup assembly 520 for sucking the membrane, and a motor assembly 530 for rotating the suction cup assembly 520 by 180°.

[0047] When implementing it, Figure 2As shown, the transport mechanism 500 includes a guide rail assembly 510 installed on the frame 100, a suction cup assembly 520 for sucking up the membrane, and a motor assembly 530 for rotating the suction cup assembly 520 180°. During operation, the suction cup assembly 520 sucks up qualified membranes, and then the guide rail assembly 510 drives the suction cup assembly 520 to move to the stacking mechanism 600. A motor is provided above the suction cup assembly 520, which is used to rotate the membrane 180° before stacking. The reason for designing the above structure is that the thickness of the membrane after processing is not uniform. Stacking the membranes by cross-stacking can eliminate the problem of uneven thickness of the stacked membranes, and the stacked membranes can eliminate local defects, making the performance of the product more superior.

[0048] Preferably, the stacking mechanism 600 includes a lifting assembly 610 for controlling the height of the stacked film to be on the same horizontal plane as the conveying mechanism 110 and a driving assembly 620 for driving the lifting assembly 610; the lifting assembly 610 includes a stacking bin 611 for holding film and a screw feeding device 612 arranged below the stacking bin 611.

[0049] When implementing it, Figure 5 As shown, in order to make the height of the diaphragm stack relatively consistent with the height of the conveying mechanism 110, a lifting assembly 610 is provided, and the lifting assembly 610 includes a stacking bin 611 for holding the diaphragms and a screw feeding device 612 arranged below the stacking bin 611. Its working process is as follows: before working, the stacking bin 611 is located at the top and is consistent with the height of the conveying mechanism 110. During working, as the diaphragms are gradually stacked, the driving assembly 620 will drive the screw feeding device 612 and then drive the stacking bin 611 to move slowly downward, so that the height of the diaphragm stack is always relatively consistent with the height of the conveying mechanism 110. Through the above-mentioned inventive concept, on the one hand, it is convenient for the conveying mechanism 500 to accurately place the diaphragms in the stacking bin 611, so that the diaphragms are stacked more neatly; on the other hand, the downward moving range of the conveying mechanism 500 does not need to be too long, which increases unnecessary costs.

[0050] Preferably, an isolation film placement mechanism 700 is further included, for placing an isolation film on the stacking mechanism 600 .

[0051] In specific implementation, when the film needs to be added with an isolation film, the present case is also provided with an isolation film placement mechanism 700 for placing the isolation film on the stacking mechanism 600. In addition, the operator can modify the number of stacked films and the number of times the isolation film is added according to the required number of stacked films by operating the control box, making the stacking machine more intelligent and more practical.

[0052] Preferably, the isolation film placement mechanism 700 includes a lifting device 710, and the lifting device 710 includes a material bin 711 for holding the isolation film and a screw feeding assembly 712 arranged below the material bin 711; a driving device 720 for driving the lifting device 710; and a conveying assembly 730 for conveying the isolation film inside the material bin 711.

[0053] When implementing it, Figure 5 As shown, in order to make the height of the stacked isolation membrane relatively consistent with the height of the conveying mechanism 110 and the membrane stack, a lifting device 710 is also provided, and the lifting device 710 includes a material taking bin 711 for holding the isolation membrane and a screw feeding assembly 712 arranged below the material taking bin 711. Its working process is as follows: before working, the material taking bin 711 is located at the bottom, and the isolation membrane filled therein is in the same height as the conveying mechanism 110; during working, as the isolation membrane is taken out by the handling assembly 730 and placed in the stacking bin 611, the driving assembly 720 drives the screw feeding assembly 712 and then drives the material taking bin 711 to move slowly upward, so that the height of the isolation membrane stack is always relatively consistent with the height of the conveying mechanism 110 and the membrane stack, which is convenient for taking out and stacking the isolation membrane.

[0054] As a preferred solution, a movable slide is synchronously provided at the bottom of the isolation film placement mechanism 700 and the stacking mechanism 600. When the stacking bin 611 is full of film sheets or the material taking bin 711 has finished taking out the isolation film, the movable slide will move to another stacking bin 611 or material taking bin 711 to continue stacking or taking out materials, and the staff needs to take out the film sheets that are full in the original stacking bin 611 or fill the original material taking bin 711 with new isolation films. With this solution, when the film sheets are full or the isolation films have finished taking out, there is no need to stop the equipment to take out the film sheets or place the isolation films, which further improves the production efficiency.

[0055] Preferably, a sampling and collecting mechanism 800 is further included for sampling and collecting the cut membrane sheets.

[0056] In specific implementation, during the film stacking process, it is necessary to sample and test the film to test the thickness of the film or to calculate the unqualified rate of the film. Therefore, the present invention also designs a sampling collection mechanism 800 for sampling and collecting the cut film. Through the operation of the control box by the staff, the sample can be clicked on the screen of the control box, and the cut film will be automatically discharged into the sampling collection mechanism 800.

[0057] Preferably, the sampling and collecting mechanism 800 includes a flip plate 810 for classifying and collecting waste membranes and sampling membranes, a cylinder assembly for driving the flip plate 810 to flip, and a sampling chamber 820 for collecting sampling membranes; the flip plate 810 is connected to the cylinder assembly and can be rotated to a certain angle under the control of the cylinder assembly so that the membranes enter different collection areas.

[0058] When implementing it, Figure 2 As shown, the sampling collection mechanism 800 includes a flip plate 810 for classifying and collecting waste film sheets and sampling film sheets, a cylinder assembly for driving the flip plate 810 to flip, and a sampling chamber 820 for collecting sampling film sheets; its working principle is that when no sampling test is performed, the flip plate 810 is controlled by the cylinder assembly to be placed vertically, and the cut unqualified film sheets will fall into the waste collection mechanism 400 on the left side of the flip plate 810. At this time, the flip plate 810 plays a role in blocking the unqualified film sheets from falling out of the waste collection mechanism 400; when the sampling test is performed, the cylinder assembly receives the sampling test signal and drives the flip plate 810 to rotate a certain angle, which allows the sampling film sheets to slide along the flip plate 810 into the sampling chamber 820, so as to facilitate the collection of the sampling film sheets. Through the above-mentioned inventive concept, the simple structure is effectively utilized to classify and collect the waste film sheets and the sampling film sheets, further improving the practicality of the device.

[0059] Preferably, it further comprises a deviation correction mechanism 900 for pulling the film onto the conveying mechanism 110 , wherein the deviation correction mechanism 900 comprises a steerable conveying deviation correction device 910 and an ultrasonic sensor 920 connected to the conveying deviation correction device 910 by signal.

[0060] When implementing it, Figure 4-5 As shown, before the film enters the appearance inspection and cutting, the film needs to be automatically adjusted to be straight by the correction mechanism 900. The correction mechanism 900 includes a steerable transmission correction device 910 and an ultrasonic sensor 920 connected to the transmission correction device 910 by signal. The transmission correction device includes a conveyor belt for conveying the film and a correction component arranged at the bottom of the conveyor belt. The correction degree of the film is sensed by the ultrasonic sensor 920 and fed back to the correction system. The correction system will send a signal to drive the transmission correction device 910 to swing left and right relative to each other during transmission, so that the transmission path of the film is in a straight line, which is convenient for the appearance inspection, cutting and stacking of the film later.

[0061] As a preferred solution, Figure 4 As shown, a trimming device 930 is also provided on the deflection correction mechanism 900 for cutting off the excess edge of the diaphragm. The trimming device 930 includes two sets of rollers that are tangential to each other, one set of rollers having a rolling cutter, and when the diaphragm passes through the middle, the excess edge of the diaphragm is cut off. A collection box is also provided inside the deflection correction mechanism 900 for collecting waste left by trimming. Integrating the deflection correction mechanism 900 and the trimming device 930 on the same device simplifies the structure and reduces the cost.

[0062] Although the terms such as frame, conveying mechanism, appearance inspection mechanism, automatic cutting mechanism, waste collection mechanism, handling mechanism, stacking mechanism, pressure roller assembly, pressure rod, pressure roller, rolling knife device, adjusting device, guide rail assembly, suction cup assembly, motor assembly, lifting assembly, driving assembly, stacking bin, screw feeding device, isolation film placement mechanism, lifting device, material bin, screw feeding assembly, driving device, handling assembly, sampling and collecting mechanism, flip plate, sampling bin, deviation correction mechanism, transmission deviation correction device, ultrasonic sensor, buffer mechanism, transition transmission device, static elimination device, trimming device, etc. are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
