DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figures 1 to 4 The utility model discloses a photovoltaic film deviation prevention device for a cutting machine, comprising:

[0033] Mounting frame 11;

[0034] The film drag chain 9 is slidably arranged in the middle of the mounting frame 11;

[0035] A film laying device, used for laying the film 15, the film laying device is installed on the mounting frame 11, and the film laying device is located above the film drag chain 9;

[0036] A plurality of visual recognition devices, mounted on one side of the mounting frame 11;

[0037] The glass plate bracket 13 is located below the mounting frame 11 and is used to transport the glass 16. The transport direction of the glass plate bracket 13 is perpendicular to the moving direction of the film drag chain 9.

[0038] A plurality of light source assemblies are fixedly connected to the glass plate bracket 13 through the mounting plate 14 and are arranged one by one corresponding to the visual recognition devices;

[0039] A plurality of glass plate position limiting and moving components are mounted on corresponding mounting plates 14 .

[0040] When in use, adjust the positions of the movable ends of the glass plate limiting moving assemblies so that they are located at the end of the glass plate bracket 13 on the side close to the visual recognition device, and transport the glass 16 by the glass plate bracket 13 until the edge of the glass 16 abuts against the movable end of the glass plate limiting moving assembly, unfold the adhesive film 15 by the adhesive film laying device and set it above the glass 16, unfold the adhesive film drag chain 9 and locate it between the glass 16 and the adhesive film 15, start the light source assembly, and identify the edge of the glass 16 and the edge of the adhesive film 15 by the visual recognition device. In the initial state, the edge of the glass 16 exceeds the edge of the adhesive film 15, and the movable end of the glass plate limiting moving assembly is moved to push the edge of the glass 16 close to the edge of the adhesive film 15 until the visual recognition device recognizes that the edge of the glass 16 coincides with the edge of the adhesive film 15. At this time, the adhesive film drag chain 9 moves out from between the glass 16 and the adhesive film 15, and the adhesive film 15 naturally falls and adheres to the surface of the glass 16. The device can move the edge of the glass 16 according to the edge position of the adhesive film 15, and can timely and effectively match the change of the laying position of the adhesive film 15 at any time, thereby improving the yield rate.

[0041] According to a further optimization scheme, the film laying device includes a film clamp 10 slidably arranged on a mounting frame 11 , one end of the film 15 is fixedly connected to the film clamp 10 , and the moving direction of the film clamp 10 is colinear with the moving direction of the film drag chain 9 .

[0042] One end of the adhesive film 15 is fixedly connected to the adhesive film clamp 10 , and the other end of the adhesive film 15 is wound around a rotating shaft (not shown in the figure). By moving the adhesive film clamp 10 , the adhesive film 15 can be pulled out from the rotating shaft and flattened.

[0043] The adhesive film 15 is laid just above the adhesive film drag chain 9 .

[0044] Furthermore, both ends of the film clamp 10 are slidably arranged on the mounting frame 11 through a linear motor. The film clamp 10 can be driven to move on the mounting frame 11 through the linear motor.

[0045] As another embodiment, the utility model can also install a transmission shaft 12 on the mounting frame 11. Two transmission shafts 12 are provided, which are symmetrically arranged at the two ends of the mounting frame 11. The mounting frame 11 is rotatably connected to the transmission shaft 12. Pulleys are fixedly connected to the two ends of the transmission shaft 12 respectively. Belts are sleeved on the pulleys on the same side of the two transmission shafts 12. The belts are fixedly connected to the ends of the film clamps 10. A driving wheel is connected to the middle axis of any transmission shaft 12. One end of the driving belt is sleeved on the driving wheel. The other end of the driving belt is sleeved with a driving wheel. The driving wheel shaft is connected to the output shaft of the driving motor. The fixed end of the driving motor is fixedly connected to the mounting frame 11.

[0046] The driving motor drives the driving wheel to rotate, and one of the transmission shafts 12 is driven to rotate under the action of the driving belt and the driving wheel, and the other transmission shaft 12 is driven by the belt to rotate at the same time. The rotation of the belt also drives the end of the film clamp 10 to move, so that the film clamp 10 can slide relative to the mounting frame 11.

[0047] The moving direction of the film clamp 10 is colinear with the moving direction of the film drag chain 9 but in opposite directions. In the initial state, the film drag chain 9 is in an unfolded state. At this time, the film clamp 10 is located on the feeding end of the film 15 of the mounting frame 11. After the film clamp 10 flattens the film 15 on the mounting frame 11, the film 15 is laid on the unfolded film drag chain 9. As the glass plate is aligned with the film 15, the film 15 begins to be pasted to the glass plate. At this time, the film drag chain 9 is retracted toward the feeding end of the film 15 of the mounting frame 11 to make the film 15 contact with the glass plate.

[0048] According to a further optimized solution, the visual recognition device includes a camera bracket 2, which is fixed to the side wall of the mounting frame 11, and the camera bracket 2 is located on the discharge end side of the glass plate bracket 13;

[0049] A camera 1 is fixedly connected to the top of the camera bracket 2, and the camera head of the camera 1 is arranged vertically downward.

[0050] According to a further optimized solution, the light source assembly includes a visual light source 6 , which is fixed to a corresponding mounting plate 14 , and the visual light source 6 is located directly below the corresponding camera 1 .

[0051] Through the illumination of the visual light source 6 , light passes through the glass 16 and the adhesive film 15 to provide brightness for the camera 1 to shoot. The visual light source 6 is preferably an LED light source.

[0052] Further optimized solution, the glass plate limit moving assembly includes a screw slide module 8, the fixed end of the screw slide module 8 is fixedly connected to the mounting plate 14, located on one side of the corresponding visual light source 6, the movable end of the screw slide module 8 is fixedly connected to the bottom end of the lifting part, and the top end of the lifting part is fixedly connected to the nylon stopper 3;

[0053] The screw shaft of the screw slide module 8 is connected to a driving part.

[0054] According to a further optimized solution, the lifting part includes a regular cylinder 5 , the bottom end of the regular cylinder 5 is fixedly connected to the movable end of the screw slide module 8 , and the top end of the regular cylinder 5 is fixedly connected to the nylon stopper 3 .

[0055] According to a further optimized solution, the driving unit includes a driving motor 7 , a fixed end of the driving motor 7 is fixedly connected to a fixed end of a screw slide module 8 , and an output shaft of the driving motor 7 is connected to a screw shaft of the screw slide module 8 .

[0056] When in use, the lead screw of the lead screw slide module 8 is driven to rotate by the driving motor 7, so that the slide of the lead screw slide module 8 can move horizontally, the slide of the lead screw slide module 8 is threadedly connected to the lead screw, and the slide of the lead screw slide module 8 is fixedly connected to the fixed end of the regular cylinder 5, and the regular cylinder 5 is used to lift the nylon stopper 3. According to the specifications of the glass 16, the height of the nylon stopper 3 is adjusted so that the nylon stopper 3 can be against the edge of the glass 16. During the initial creation, the nylon stopper 3 is located at the edge of the glass plate bracket 13 close to the camera 1. After the glass 16 is pushed to the bottom by the glass plate bracket 13, the edge of the glass 16 abuts against the nylon stopper 3. At this time, it is necessary to ensure that the edge of the glass 16 exceeds the edge of the film 15, and then the lead screw is rotated to gradually push the edge of the glass 16 to overlap with the edge of the film 15, and then the film 15 and the glass 16 are pasted.

[0057] The working process of the utility model is as follows:

[0058] The photovoltaic glass 16 is transmitted to the inside of the cutting machine through the conveyor line, supported by the glass plate bracket 13, and moved to the edge of the glass plate bracket 13. After the detection sensor arranged inside the cutting machine senses that the glass 16 enters the glass plate bracket 13, the regularizing cylinder 5 drives the nylon stopper 3 to extend to block the glass 16 to achieve pre-positioning.

[0059] The film clamp 10 pulls out the cut film 15, moves to the laying position and places it on the film drag chain 9 above the glass 16.

[0060] At this time, the visual system starts to collect images and calculate the position deviation distance between the edge of the film 15 and the edge of the glass 16. After the calculation is completed, the result is transmitted to the drive motor 7, and the drive motor 7 drives the lead screw slide module 8 to make the regular cylinder 5 drive the nylon block to push the glass 16 to move a suitable distance for precise positioning.

[0061] After the adhesive film 15 is applied, the driving motor 7 drives the lead screw slide module 8 to return the aligning cylinder 5 to the waiting position and the aligning cylinder 5 is retracted, and the glass 16 with the adhesive film 15 applied flows out.

[0062] Return to step ① and loop.

[0063] Visual Work Description:

[0064] If the specified distance between the edge of the film 15 and the edge of the glass 16 is 2 mm, the visual system detects that the actual distance between the edge of the film 15 and the edge of the glass 16 is 8 mm, and the distance deviation is 6 mm. The visual system transmits the information to the drive motor 7, and the drive motor 7 drives the lead screw slide module 8 to move the edge of the glass 16 toward the edge of the film 15 by 6 mm, thereby achieving precise positioning.

[0065] Since the waiting position of the nylon stopper 3 of the regular cylinder 5 is always away from the edge direction of the adhesive film 15, the result of visual detection is always a positive deviation, avoiding the occurrence of a negative deviation.

[0066] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0067] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
