Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically to a film and tape material handling device. Background Technology

[0002] Back-contact (BC) cells are solar cells where both the emitter and base electrodes are located on the back of the cell. They offer advantages such as fewer manufacturing steps, higher conversion efficiency, and a more aesthetically pleasing appearance.

[0003] In the production of BC batteries, the battery cells need to be coated. Before coating, the cut film strips need to be moved onto the battery cells. In the existing technology, multiple film strips usually need to be moved at one time. However, the distance between the suction cups on the existing conveying device is fixed. When the distance between the film strips needs to be adjusted, a new conveying device needs to be designed. Utility Model Content

[0004] To address the problems in the prior art, this application provides a membrane belt material handling and conveying device, which can pick up and move membrane belts with different spacings.

[0005] The technical solution is as follows:

[0006] The device includes a mounting plate, a driving assembly on its top, and a fixed mounting plate and a movable mounting plate on its bottom. The fixed mounting plate is connected to the mounting plate via a connecting rod. A cylinder is located at the bottom of the mounting plate, driving the movable mounting plate to move. Suction cups are located at the bottom of both the fixed and movable mounting plates, and air passage plates are located at the top of both plates, with air passages communicating with the suction cups inside the air passage plates.

[0007] Preferably, the mounting plate has a mounting groove at its bottom, and the suction cup is disposed in the mounting groove.

[0008] Preferably, the suction cup protrudes from the surface of the mounting plate, and the distance between the suction cup and the surface of the mounting plate is 1mm-2mm.

[0009] Specifically, the drive assembly has a guide seat on its side, and a guide rod is provided inside the guide seat. The bottom end of the guide rod is connected to the top of the mounting plate.

[0010] Specifically, the air circuit board is provided with a clearance groove for the connecting rod to pass through.

[0011] Specifically, the air circuit board has several air circuits inside, one of which is connected to at least one of the suction cups.

[0012] Specifically, the drive assembly includes a lead screw and a motor, and the mounting plate is connected to the lead screw.

[0013] In summary, the combination of fixed and movable mounting plates allows for adjustment based on the distance between membrane belts, eliminating the need for additional design and manufacturing and significantly reducing production costs. Furthermore, each fixed and movable mounting plate is equipped with an air passage plate, which connects to an external air source, effectively reducing the number of air pipes and facilitating unified management of the suction cups and subsequent maintenance.

[0017] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0018] like Figure 1 As shown, the top and bottom of the mounting plate 1 are respectively equipped with a drive assembly 7 and a mounting plate. The drive assembly 7 enables vertical lifting and lowering. It should be noted that if more movement functions are required, such as horizontal movement, the drive assembly 7 can also be connected to a horizontal moving device, which can be a lead screw module or a belt drive device. The mounting plate includes a fixed mounting plate 4 and a movable mounting plate 5. The fixed mounting plate 4 is connected to the mounting plate 1 via connecting rods 2. The number of connecting rods 2 is calculated based on the weight of the fixed mounting plate 4. Here, four connecting rods 2 are used to improve the connection's strength. The movable mounting plate 5 is connected to the mounting plate 1 via a cylinder 6. One side of the cylinder 6 is fixed to the mounting plate 1, and the output end is connected to the movable mounting plate 5, allowing the movable mounting plate 5 to move. This allows adjustment of the distance between the movable mounting plate 5 and the fixed mounting plate 4.

[0019] Furthermore, the movable mounting plate 5 can be set according to the number of film strips to be gripped at one time. If three film strips need to be gripped, then two movable mounting plates 5 are set, and so on. The figure shows that two film strips are gripped at one time, so one movable mounting plate 5 is set.

[0020] like Figure 2 As shown, the suction cup 10 is installed at the bottom of the fixed mounting plate 4 and the movable mounting plate 5. To facilitate ventilation of the suction cup 10, an air passage plate 3 is installed at the top of both the fixed mounting plate 4 and the movable mounting plate 5. Air passages are opened inside the air passage plate 3, which are connected to the suction cup 10. An air port is provided on the air passage plate 3 to connect to an external air source, and ventilation of the suction cup 10 is achieved through the air source connection to the air port.

[0021] It should be noted that the air circuit board 3 is fixed on the top surface of the movable mounting plate 5. Therefore, the output end of the cylinder 6 can be directly connected to the movable mounting plate 5 or directly connected to the air circuit board 3, as long as the movable mounting plate 5 can be moved.

[0022] An external air source is connected to the air port of the air circuit board 3. When the distance between the membrane strips increases, the cylinder 6 operates, controlling the movable mounting plate 5 to move outward to the designated position; conversely, when the distance between the membrane strips decreases, the cylinder 6 moves in the opposite direction. The drive assembly 7 drives the mounting plate 1 downward, causing the suction cups 10 on the fixed mounting plate 4 and the movable mounting plate 5 to pick up the membrane strips respectively. After the membrane strips are picked up, the drive assembly 7 controls the mounting plate 1 to rise to the designated position, and then the horizontally moved device is driven to the designated position.

[0023] like Figure 2 As shown, several mounting slots are provided at the bottom of the mounting plate 1 to fix the suction cup 10 inside the mounting slots. The number of mounting slots is set according to the number of suction cups 10. This can effectively reduce the area of ​​the suction cup 10 exposed to the outside, avoid the aging of the rubber of the suction cup 10 caused by external factors, and also prevent external damage to the suction cup 10, thereby improving the service life of the suction cup 10.

[0024] To avoid affecting the adhesion of the suction cup 10 to the film strip, and to minimize the exposed area of ​​the suction cup 10, the suction cup 10 is designed to protrude from the mounting plate 1, with the distance between the suction cup 10 and the surface of the mounting plate 1 being 1mm-2mm. Specifically, the distances between the suction cup 10 and the surface of the mounting plate 1 are 1mm, 1.5mm, and 2mm.

[0025] like Figure 1As shown, guide seats 9 are symmetrically installed on the outer side of the drive assembly 7, and guide rods 8 are inserted inside the guide seats 9. The bottom of the guide rods 8 is fixedly connected to the top of the mounting plate 1. During the lifting and lowering of the mounting plate 1, the cooperation of the guide seats 9 and guide rods 8 on both sides ensures the stability and accuracy of the lifting and lowering, and avoids deviation during the lifting and lowering process.

[0026] The air circuit board 3 is provided with a clearance groove 11, which allows the connecting rod 2 to pass through and connect with the fixed mounting plate 4.

[0027] Specifically, the air circuit board 3 has multiple air circuits inside, and each air circuit can connect to at least one suction cup 10. For example, if one air circuit connects to one suction cup 10, then the suction cup 10 can be precisely and independently controlled. However, the air circuit board 3 would need to have multiple air ports and connect to multiple air tubes, which is not conducive to assembly and maintenance. To achieve a balance, one air circuit is connected to six suction cups 10, which reduces the number of air tubes while still allowing for precise control of the suction cups 10, making assembly and maintenance easier.

[0028] The drive assembly 7 here includes a lead screw and a motor. The mounting plate 1 is mounted on a slider on the lead screw. The motor is connected to the lead screw and drives the lead screw to rotate.

[0029] In actual use, an external air source is connected to the air port of the air circuit board 3. When the distance between the membrane strips increases, the cylinder 6 operates, controlling the movable mounting plate 5 to move outward to the designated position. The motor of the drive assembly 7 drives the mounting plate 1 to move downward, and the suction cups 10 on the fixed mounting plate 4 and the movable mounting plate 5 respectively pick up the membrane strip. After the membrane strip is picked up, the drive assembly 7 controls the mounting plate 1 to rise to the designated position, and then the horizontally moved device is driven to the designated position.

[0030] When the distance between the membrane strips decreases, cylinder 6 operates, controlling the movable mounting plate 5 to move inward to the designated position. Drive assembly 7 drives mounting plate 1 downward, causing suction cups 10 on fixed mounting plate 4 and movable mounting plate 5 to pick up the membrane strips respectively. After the membrane strips are picked up, drive assembly 7 controls mounting plate 1 to rise to the designated position, which is then moved to the designated position by the horizontal moving equipment.

This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not described herein.
