[0002] To prevent the screen from being scratched during transportation, the screen is usually covered with a protective film before shipment. The protective film needs to be peeled off before product assembly. Since the screen assembly process is very strict about the control of foreign matter, in order to avoid dust contamination of the screen during assembly, the film peeling process needs to reduce manual operations as much as possible.

[0053] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0054] The film tearing device of the present invention will be described below with reference to the accompanying drawings.

[0055] like Figure 1 and Figure 3 As shown, the utility model provides a film tearing device, wherein the film tearing device comprises:

[0056] The conveying device 1 is provided with an input end and an output end of the product to be torn off;

[0057] The film-lifting device 2 can be raised and lowered and can pull up the film-lifting end of the first film of the film-tearable product;

[0058] The film tape winding device 3 comprises a winding mounting frame 31, a first winding mechanism 32 and a first film pressing member 33. The winding mounting frame 31 is located between the film starting device 2 and the output end. The first winding mechanism 32 is arranged on the winding mounting frame 31. The first film pressing member 33 is arranged on the first winding mechanism 32. The first winding mechanism 32 and the first film pressing member 33 can cooperate to press the first film.

[0059] The first film clamping device 4 is movably arranged to clamp the film starting end of the first film sheet pulled up by the film starting device 2 and transfer it to the first winding mechanism 32 .

[0060] When the above-mentioned film tearing equipment is used, the conveying device 1 drives the product to be torn off to move, and the film pulling device 2, the first film clamping device 4 and the film tape winding device 3 are arranged in sequence along the conveying device 1. The conveying device 1 can be raised and lowered and can pull up the film pulling end of the first film sheet of the product to be torn off to complete the film pulling work. Then the first film clamping device 4 clamps the film pulling end of the first film sheet pulled up by the film pulling device 2 and transfers it to the first winding mechanism 32. The first winding mechanism 32 and the first film pressing member 33 cooperate to press the film pulling end of the first film sheet. Then the first winding mechanism 32 starts to rotate to realize the winding of the first film sheet. Then, the film pulling and tape winding work of the first film sheet can be realized through the film tearing equipment. The entire film tearing process does not require manual intervention, which avoids the pollution of the product caused by dust generated by manual film tearing.

[0061] In the embodiment of the utility model, the film peeling device further comprises a film pressing device 6, which is arranged on the conveying device 1 and between the input end and the film peeling device 2. The film pressing device 6 is arranged across the transmission surface of the conveying device 1 and can press the first film and the product to be peeled onto the conveying device 1. Figure 1 and Fig.10 The film tearing equipment adopts a material box 91 for loading, and the input end of the conveying device 1 is connected to a guide plate 92 arranged to be tilted downward, and the opening of the material box 91 faces the guide plate 92. The first film sheet covers multiple products to be torn off at the same time, and multiple products to be torn off are stacked in a Z shape in the material box 91. When loading, the first film sheet and the product to be torn off are pressed by the film pressing device 6 at the same time, thereby driving the subsequent products to be torn off from the material box 91 along the guide plate 92 into the conveying device 1.

[0062] like Figure 8 As shown, in the embodiment of the utility model, the film pressing device 6 includes a film pressing mounting frame 61, a clamping drive member 62, a transmission roller mounting seat 63 and a clamping transmission roller 64. The film pressing mounting frame 61 is arranged on the conveying device 1 and is arranged across the transmission surface. The fixed end of the clamping drive member 62 is arranged on the film pressing mounting frame 61, and the telescopic end faces the transmission surface and is drivingly connected to the transmission roller mounting seat 63. The clamping transmission roller 64 is rotatably mounted on the transmission roller mounting seat 63. The height of the clamping transmission roller 64 can be adjusted by the clamping drive member 62. On the one hand, the clamping force can be adjusted. On the other hand, the distance between the clamping transmission roller 64 and the transmission surface can be adjusted according to the thickness of the product to be torn off. Specifically, the clamping drive member 62 is preferably a cylinder, and the clamping force on the product to be torn off can be set by adjusting the air pressure of the cylinder.

[0063] like Figure 1 and Figure 7As shown, in the embodiment of the utility model, the film pressing device 6 also includes an auxiliary pressure rod assembly located between the film pressing mounting frame 61 and the film lifting device 2, and the auxiliary pressure rod assembly includes a film pressing rod 65 and a pressure rod mounting seat 66 arranged on the conveying device 1, and the film pressing rod 65 is arranged on the pressure rod mounting seat 66 and spans the transmission surface. As the film lifting device 2 pulls the film lifting end of the first film sheet to move upward, the first film sheet will gradually separate from the film-to-be-torn product, and will be in an upward tilted state along the transmission direction. The initial separation position is upstream of the film lifting device 2. The tilted first film sheet is easy to scrape against the lifting track of the film lifting device 2, and it is very easy to produce debris. At the same time, there is also a risk of damaging the film lifting device 2. The utility model can limit the height of the first film sheet below the film lifting device 2 by setting an auxiliary pressure rod assembly. Specifically, the distance between the film pressing rod 65 and the transmission surface does not exceed the distance between the lifting track and the transmission surface, ensuring that the first film sheet will not scrape against the lifting track.

[0064] like Figure 4 As shown, in the embodiment of the utility model, the film strip winding device 3 also includes a buffer roller assembly, which includes a buffer mounting seat 35 and a buffer roller 36. The buffer mounting seat 35 is arranged on the winding mounting frame 31 and is located between the first winding mechanism 32 and the film starting device 2. The buffer roller 36 can be raised and lowered on the buffer mounting seat 35 and supports the tensioning of the first film. Before the first film is rolled up to the first winding mechanism 32, the height of the buffer roller 36 can be adjusted so that the buffer roller 36 abuts against the first film to achieve tensioning of the first film, so that the first film is evenly wound on the first winding mechanism 32, and the winding effect of the first film is ensured.

[0065] Specifically, when the first film sheet is separated from the product to be torn off, static electricity is generated due to the friction between the two, causing the first film sheet to be in a wrinkled state before entering the first winding mechanism 32, affecting the winding effect. Therefore, the film strip winding device 3 provided by the utility model also includes an electrostatic ion rod 37. The electrostatic ion rod 37 is made of conductive material and is arranged between the buffer roller assembly and the film-forming device 2. It can quickly eliminate the static electricity attached to the first film sheet and ensure the winding effect.

[0066] In the embodiment of the utility model, the first winding mechanism 32 includes an inflatable shaft 321 rotatably arranged on the winding mounting frame 31, and the first film pressing member 33 is formed with a pressing surface 331 arranged toward the key strip 322 of the inflatable shaft 321, and the pressing surface 331 and the key strip 322 of the inflatable shaft 321 clamp and fix the first film. After the first film clamping device 4 pulls the first film onto the inflatable shaft 321, the inflatable shaft 321 is ventilated and expanded, and the key strip 322 on the inflatable shaft 321 extends and presses the first film against the pressing surface 331 of the first film pressing member 33, and then the inflatable shaft 321 is driven by a torque motor arranged on the other side wall of the winding mounting frame 31 to drive the first film to rotate together, and the torque motor can ensure continuous winding with constant tension, and can increase the output torque in a synchronous ratio with the increase of the winding diameter, so that the first film can be wound more tightly on the inflatable shaft 321, thereby completing the winding of the first film.

[0067] Specifically, the first film pressing member 33 includes a connecting portion and a clamping portion. The connecting portion is arranged on the inflatable shaft 321, and the clamping portion extends horizontally from the connecting portion along the axial direction of the inflatable shaft 321. The clamping portion is formed with a groove on one side of the inflatable shaft 321, and the bottom of the groove is a clamping surface 331. The key strip 322 can be extended into the groove to ensure the reliability of clamping the first diaphragm and prevent the first diaphragm from falling out during winding.

[0068] In an embodiment of the utility model, the first film clamping device 4 includes a first film clamping mounting frame 41, a first translation mechanism 42, a second translation mechanism 43 and a first film clamping mechanism 44. The first film clamping mounting frame 41 is located on one side of the conveying device 1, the first translation mechanism 42 is arranged on the first film clamping mounting frame 41, the second translation mechanism 43 is arranged on the first translation mechanism 42 and can be moved along the transmission direction of the conveying device 1 under the drive of the first translation mechanism 42, and the first film clamping mechanism 44 is arranged on the second translation mechanism 43 and can be moved along the axial direction of the inflatable shaft 321 under the drive of the second translation mechanism 43.

[0069] The working process of the first film clamping device 4 is as follows:

[0070] After the film-forming device 2 completes the film-forming work, the first film clamping mechanism 44 clamps the film-forming end of the first film sheet;

[0071] The first translation mechanism 42 drives the second translation mechanism 43 to move toward the output end of the conveying device 1 and exceed the first winding mechanism 32;

[0072] The second translation mechanism 43 drives the first film clamping mechanism 44 to move along the axial direction of the inflatable shaft 321 , so that the film starting end of the first film sheet enters into the gap between the pressing portion of the first film clamping member 33 and the inflatable shaft 321 .

[0073] After the key strip 322 of the inflatable shaft 321 cooperates with the pressing portion to press the first diaphragm, the first film clamping mechanism 44 is relaxed and reset.

[0074] The first film clamping device 4 can realize the transfer of the film starting end of the first film, ensuring that the film strip winding device 3 has enough space to wind up the first film. Specifically, the first film clamping device 4 also includes a first lifting mechanism 45, and the first translation mechanism 42 drives the first lifting mechanism 45 to move along the first film clamping mounting frame 41. The first lifting mechanism 45 drives the second translation mechanism 43 to adjust the height of the first film clamping mechanism 44, ensuring that the film starting end of the first film can enter the gap between the pressing part of the first film pressing member 33 and the air shaft 321.

[0075] The film-lifting device 2 includes a film-lifting mounting frame 21, a film-lifting mounting seat 22, a film-lifting rubber roller 23 and an auxiliary rubber roller 24. The film-lifting mounting frame 21 is arranged across the conveying device 1, and the film-lifting mounting seat 22 is arranged on the film-lifting mounting frame 21 so as to be liftable. The film-lifting rubber roller 23 and the auxiliary rubber roller 24 are rotatably arranged on the film-lifting mounting frame 21 in sequence and in parallel along the height direction of the film-lifting mounting frame 21, and the film-lifting rubber roller 23 is located on the side of the auxiliary rubber roller 24 facing the conveying device 1. The surfaces of the film-lifting rubber roller 23 and the auxiliary rubber roller 24 are both covered with an adhesive layer that can be glued to the first film. When filming, the film-lifting mounting seat 22 moves downward to make the film-lifting rubber roller 23 contact the first film, and the film-lifting rubber roller 23 rolls and brings up the first film. After the first film is rolled between the film-lifting rubber roller 23 and the auxiliary rubber roller 24, the film-lifting mounting seat 22 moves upward to complete the film-lifting work. The film-lifting rubber roller 23 and the auxiliary rubber roller 24 squeeze the first film from both sides respectively, increasing the friction between the first film and the rubber roller, and preventing the first film from falling off the film-lifting rubber roller 23 when the film-lifting mounting seat 22 rises. Of course, the utility model is not limited to this, and the film-lifting device 2 can also be set in the form of a suction nozzle, adhesive tape, etc.

[0076] In an embodiment of the utility model, the film starting device 2, the first winding mechanism 32 and the first film clamping device 4 are all located on the upper side of the conveying device 1. The film strip winding device 3 also includes a second winding mechanism 34 arranged on the winding mounting frame 31 and a second film pressing member arranged on the second winding mechanism 34. The second winding mechanism 34 is located on the lower side of the conveying device 1. The second film pressing member can press the film starting end of the second film sheet of the product to be torn off onto the second winding mechanism 34. The film tearing equipment also includes a second film clamping device 5. The second film clamping device 5 can be raised and lowered and clamp the film starting end of the second film sheet from the lower side of the conveying device 1 and transfer it to the second winding mechanism 34. For products such as screens, both sides need to be covered with film for protection during transportation. In the utility model, the first film refers to the film covering the upper side of the product, and the second film refers to the film covering the lower side of the product. The above-mentioned film tearing equipment can separate the films on the upper and lower sides of the product to be torn off at the same time, which has higher film tearing efficiency and effectively reduces manual operation labor. In addition, since there is no need to flip the product to be torn off, the floor space occupied by the film tearing equipment can be reduced, which can improve the utilization rate of the workshop area for factory layout.

[0077] Specifically, the conveying device 1 includes a first conveying section 11 and a second conveying section 12 arranged in sequence along the transmission direction, the starting point of the first conveying section 11 is the input end of the film product to be torn, and the end point of the second conveying section 12 is the output end of the film product to be torn, the film starting device 2 is located above the first conveying section 11, the film pressing device 6 is arranged on the first conveying section 11, and the winding mounting frame 31 is arranged on the side plate of the second conveying section 12. The first conveying section 11 and the second conveying section 12 are separated by a feed opening for the second winding mechanism 34 to roll the second film downward; the second film clamping device 5 includes It includes a second film clamping mounting frame 51 located below the discharge port and a second lifting mechanism 52, a third translation mechanism 53, a fourth translation mechanism 54 and a second film clamping mechanism 55 connected in sequence. The second film clamping mechanism 55 is used to clamp the second film sheet. The second lifting mechanism 52 drives the third translation mechanism 53 to rise and fall along the second film clamping mounting frame 51. The third translation mechanism 53 and the fourth translation mechanism 54 are used to adjust the horizontal position of the second film clamping mechanism 55 so that the second film sheet clamped by the second film clamping mechanism 55 enters the gap between the second winding mechanism 34 and the second film pressing member.

[0078] Furthermore, in the specific embodiment of the utility model, the first film clamping mechanism 44 is preferably a pneumatic clamping jaw, and the second film clamping mechanism 55 is preferably a pneumatic pressing block, but other driving modes (such as hydraulic pressure) are also possible. The lifting mechanism and the translation mechanism can be selected from cylinder drive, screw drive, etc. according to the requirements of the moving distance and moving accuracy.

[0079] It should be noted that the first winding mechanism 32 and the second winding mechanism 34 , and the first film pressing member 33 and the second film pressing member have the same structure, so they will not be described in detail.

[0080] In the embodiment of the utility model, a dust removal device 7 is provided at each of the input end and the output end of the conveying device 1, and the dust removal device 7 is used to clean the dust on the surface of the product, thereby improving the yield rate of the product. Specifically, the dust removal head of the dust removal device 7 has an ultrasonic generating chamber and two vacuum adsorption chambers, and the ultrasonic generating chamber is used to emit ultrasonic waves, and the dust on the surface of the product is driven by the reflection of the ultrasonic waves, and the moving dust is instantly sucked away by the vacuum adsorption chamber, thereby achieving the effect of cleaning the dust on the glass surface.

[0081] In the embodiment of the utility model, the film tearing equipment also includes a feeding device 8, which is arranged near the output end and can transfer the product on the output end.

[0082] Specifically, the working process of the film tearing device provided by the utility model is as follows:

[0083] The first film to be torn off in the material box 91 is placed on the input end of the conveying device 1, and the transmission roller 64 is pressed down to press the film to be torn off, and the film to be torn off product is transmitted to the film tearing position. After the film to be torn off product is rolled and film-torn by the film-torn rubber roller 23, the first film sheet will stick to the surface of the film-torn rubber roller 23 as the film-torn rubber roller rolls, and then transferred to between the film-torn rubber roller 23 and the auxiliary rubber roller 24, and then the film-torn mounting seat 22 rises, so that the first film clamping device 4 can clamp the first film sheet, and the first film sheet is pulled to the winding position through the first film clamping device 4, and the first film sheet is collected by the air shaft 321; at the same time as the first film is torn off, because the first film sheet and the film to be torn off product have been separated, and then the second film sheet will protrude from the product, the second film tearing device can directly press the second film sheet, and descend to the second film sheet pulling winding position, and the second film sheet is collected by the air shaft 321; after the product completes double-sided film tearing, it directly flows into the output end, and then the four-axis robot completes the unloading.
