Technical Field

[0001] This utility model belongs to the field of coated battery string production technology, and in particular relates to a film strip material clamp, a film strip material feeding mechanism and a string welding machine. Background Technology

[0002] In the production process of photovoltaic (PV) cell strings, more advanced modules now coat each cell with an EVA film. However, the handling of this film is still primarily manual. Even with the use of film cutting equipment, such as the invention application published in Chinese patent application CN117719923A, the feeding mechanism includes at least two first feeding components and / or at least two second feeding components, and the gripping device includes at least two first grippers and / or at least two second grippers. Along the length of the PV film feeding device, the first and second feeding components are arranged sequentially; along the width of the PV film feeding device, each first feeding component and each second feeding component is arranged sequentially. However, this first and second gripper can only grip strip-shaped films and does not specifically mention the specific structure and implementation of the grippers.

[0003] A film feeding device is proposed, which involves traction and transportation of the film and then pressing the film onto a conveyor belt for transport. This requires traction and transportation of the film, thus necessitating a novel film belt material gripper to achieve the function of traction and transportation of the film. Summary of the Invention

[0004] The main purpose of this utility model is to provide a membrane tape material gripper, a membrane tape material feeding mechanism, and a string welding machine, which can solve the problem of membrane tape materials being unable to be pulled during membrane tape handling.

[0005] This utility model achieves the above objectives through the following technical solution:

[0006] On the one hand, this utility model provides a film tape material gripper, including an upper gripper block, a lower gripper block, and a first driving unit that drives the upper gripper block and the lower gripper block to be close to each other or far apart.

[0007] Specifically, it also includes a mounting plate, with the fixed end of the first drive unit mounted on the mounting plate, and the telescopic end of the drive unit rotatably connected to the upper or lower clamping block.

[0008] In one possible implementation, the upper clamping block is fixedly mounted on the mounting plate, and the lower clamping block is hinged to the telescopic end of the first drive unit.

[0009] In another possible implementation, the lower clamping block is fixedly mounted on the mounting plate, and the upper clamping block is hinged to the telescopic end of the first drive unit.

[0010] Preferably, two sets of first drive units are fixedly mounted on the mounting plate, corresponding to two sets of upper and lower clamping blocks.

[0011] Preferably, the lower clamping block is arranged in a "Z" shape, and the gap left on the upper surface of the lower clamping block is configured to accommodate the upper clamping block.

[0012] Furthermore, a rotating groove is provided on the mounting plate corresponding to the upper clamping block. One end of the upper clamping block is pressed into the gap, and the other end of the upper clamping block is rotatably set in the rotating groove.

[0013] Specifically, a hinge block is also connected between the upper clamping block and the first driving unit. One end of the hinge block is hinged to the telescopic end of the first driving unit, and the other end of the hinge block is hinged to the upper clamping block body.

[0014] Preferably, both the upper and lower clamping blocks have anti-slip components on their contact surfaces.

[0015] On the other hand, this utility model also provides a film belt material feeding mechanism, including a conveying device, a film belt material gripper as described above, and a lateral movement force device for driving the film belt material gripper, wherein the lateral movement force device drives the film belt material gripper to move above the conveying device.

[0016] Specifically, the lateral movement power device includes a second drive unit and a fixed plate. The fixed end of the second drive unit is fixed on the fixed plate, and the movable end of the second drive unit drives the synchronous wheel and the synchronous belt. The synchronous belt is fixedly connected to the mounting plate.

[0017] Preferably, the mounting plate is slidably connected to the fixing plate via a slide rail slider.

[0018] Finally, this utility model also provides a string welding machine, including a battery string forming assembly and a coating assembly, wherein the coating assembly adopts a film and tape material feeding mechanism as described above.

[0019] Compared with the prior art, the advantages of this utility model of a membrane tape material gripper, a membrane tape material feeding mechanism, and a string welding machine are as follows:

[0020] (1) By converting the telescopic power of the first drive unit into the clamping force between the upper and lower clamping blocks, the diaphragm is clamped, and the diaphragm is clamped using a simple and compact hinged link.

[0021] (2) By setting the lateral force device, the gripper can move back and forth, and after the gripper holds the diaphragm, the diaphragm can be pulled by the lateral force device to move to the predetermined position for diaphragm placement, which improves the adaptability and flexibility of diaphragm feeding.

[0028] Reference Figure 3 and Figure 4 As shown in the figure, this utility model provides a film tape material gripper, including an upper gripper 1, a lower gripper 2, and a first driving unit 3 that drives the upper gripper 1 and the lower gripper 2 to be close to or away from each other. As can be seen from the figure, it also includes a mounting plate 4. The fixed end of the first driving unit 3 is mounted on the mounting plate 4, and the telescopic end of the driving unit is rotatably connected to the upper gripper 1 or the lower gripper 2.

[0029] In order to realize the opening and closing action of the upper clamping block 1 and the lower clamping block 2, the upper clamping block 1 is fixedly installed on the mounting plate 4, and the lower clamping block 2 is hinged to the telescopic end of the first drive unit 3. Of course, it is not only the above connection method. The lower clamping block 2 can also be fixedly installed on the mounting plate 4, and the upper clamping block 1 can be hinged to the telescopic end of the first drive unit 3. For cost and practical use considerations, the first drive unit 3 uses a cylinder. Of course, for more precise purposes, a more expensive electric cylinder or lead screw can also be used, which will not be elaborated here.

[0030] In practice, in order to adapt to different diaphragm widths, two sets of first drive units 3 are fixedly installed on the mounting plate 4, and corresponding to two sets of upper clamping blocks 1 and lower clamping blocks 2. The two sets of upper clamping blocks 1 and lower clamping blocks 2 clamp the two sides of one side of the diaphragm respectively. When dealing with different diaphragm widths, only the corresponding mounting plate 4 needs to be replaced to achieve compatible clamping.

[0031] In this embodiment, in order to clamp the diaphragm more tightly, the lower clamping block 2 is arranged in a "Z" shape. The gap 5 left on the upper surface of the lower clamping block 2 is configured to accommodate the upper clamping block 1. When clamping, the upper clamping block 1 presses on the plane of the lower clamping block 2, and the bottom surface of the upper clamping block 1 and the plane of the lower clamping block 2 are pressed together. The diaphragm is placed in the gap, thereby achieving the clamping of the diaphragm.

[0032] To reduce the overall thickness of the device, in this embodiment, the upper clamping block 1 is embedded within the mounting plate 4. Specifically, the mounting plate 4 has a rotating groove 6 corresponding to the upper clamping block 1. One end of the upper clamping block 1 is pressed tightly into the gap 5, while the other end of the upper clamping block 1 is rotatably positioned within the rotating groove 6. (See details...) Figure 3 As shown in the figure, in this implementation, the other end of the upper clamping block 1 is connected to the rotating groove 6 via a rotating shaft, with both ends of the rotating shaft passing through the rotating groove 6, and the other end of the upper clamping block 1 is rotatably mounted on the rotating shaft.

[0033] In this scheme, the specific connection method is as follows: a hinge block 7 is also connected between the upper clamping block 1 and the first driving unit 3. One end of the hinge block 7 is hinged to the telescopic end of the first driving unit 3, and the other end of the hinge block 7 is hinged to the body of the upper clamping block 1.

[0034] In practice, to prevent the diaphragm from sliding or shifting during clamping, anti-slip components are provided on the contact surfaces of both the upper clamping block 1 and the lower clamping block 2. These anti-slip components can be anti-slip rubber sheets or polyurethane sheets, which are adhered to the lower surface of the upper clamping block 1 and the surface of the lower clamping block 2.

[0035] In another embodiment of the invention, such as Figure 1 and Figure 2 As shown, a film belt material feeding mechanism includes a conveying device S, a film belt material gripper as described above, and a lateral movement force device 8 for driving the film belt material gripper. The lateral movement force device 8 drives the film belt material gripper to move above the conveying device S.

[0036] In this embodiment, the lateral movement device 8 includes a second drive unit and a fixed plate 9. The fixed end of the second drive unit is fixed to the fixed plate 9, and the movable end of the second drive unit drives a synchronous pulley and a synchronous belt 12. The synchronous belt 12 is fixedly connected to the mounting plate 4. The second drive unit is a motor, which drives the synchronous pulley, which in turn drives the synchronous belt 12 to move. Because the mounting plate 4 is fixed to the synchronous belt 12, the synchronous belt 12 also drives the mounting plate 4 to slide. Of course, in order to make the sliding smoother, the mounting plate 4 is slidably connected to the fixed plate 9 through a slide rail 10 and a slider 11.

[0037] Finally, in this embodiment of the present invention, a string welding machine is also provided, including a battery string forming assembly and a coating assembly, wherein the coating assembly adopts a film and tape material feeding mechanism as described above.

[0038] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
