Description

Technical Field

[0001] This utility model relates to the field of solar cell string production technology, specifically to a film gripper and transfer device. Background Technology

[0002] BC coated battery strings are back-contact battery strings that use an adhesive film to fix the solder ribbon to the back of the battery cells. Utility model patent CN221253005U discloses a film-gripping device, including a base, a main film-gripping component, a secondary film-gripping assembly, and a drive mechanism. The drive mechanism and the main film-gripping component are respectively located at the top and bottom of the base, and the secondary film-gripping components are located on both sides of the main film-gripping component. The main and secondary film-gripping components simultaneously adsorb the adhesive film. The drive mechanism can drive the two secondary film-gripping components to move upwards and closer to each other, lifting the two long sides of the adhesive film to avoid the clamps holding the solder ribbon, thereby improving the positioning accuracy of the solder ribbon layup.

[0003] However, during actual transport, the main gripper adsorbs the middle area of ​​the adhesive film, while the secondary gripper adsorbs the areas on both sides of the middle area. When the secondary gripper moves upward relative to the main gripper, due to the small adsorption area of ​​the secondary gripper, the high moving speed of the secondary gripper, and the certain hardness of the adhesive film, the areas on both sides corresponding to the long side of the adhesive film are prone to detach from the secondary gripper. This can cause interference with the clamps used for laying the welding ribbon when laying the adhesive film. Utility Model Content

Detailed Implementation

[0025] The technical solution and effects of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In the description of this embodiment, relational terms such as "first" and "second" are used only to distinguish the first feature from the second feature, and do not necessarily require or imply any such actual relationship or order between these features.

[0028] like Figures 1-3 As shown, this utility model provides a film gripper 100, including: a mounting plate 110 and a movable plate 120. The movable plate 120 is disposed below the mounting plate 110 and is elastically connected to the mounting plate 110. The bottom of the movable plate 120 is provided with a first adsorption structure 123, and the two opposite sidewalls of the movable plate 120 are also provided with a second adsorption structure 124.

[0029] The first adsorption structure 123 is used to adsorb the central area of ​​the adhesive film 30, and the second adsorption structure 124 is used to adsorb the two side areas of the adhesive film 30. After the adhesive film 30 is adsorbed by the film gripper 100, it is not easy to separate from the film gripper 100. The movable plate 120 is elastically connected to the mounting plate 110 by a spring, which can play a buffering role when the film gripper 100 grips the adhesive film 30.

[0030] In this embodiment, the bottom of the movable plate 120 is provided with a first protrusion 125. The bottom surface of the first protrusion 125 is provided with a groove, which faces the two sidewalls provided with the second adsorption structure 124. The adsorption surface of the first adsorption structure 123 is flush with the bottom surface of the first protrusion 125. When the film gripper 100 is used to lay the adhesive film 30, the welding ribbon 20 is first laid on the battery cell 10, and then the adhesive film 30 is laid, so that the groove is aligned with the welding ribbon 20. The first protrusion 125 is then pressed on the adhesive film 30 located on both sides of the welding ribbon 20, so that the adhesive film 30 is in close contact with the battery cell 10, which is beneficial for the adhesive film 30 to adhere to the battery cell 10 after being heated and melted.

[0031] In this embodiment, the movable plate 120 includes a base plate 121 and a flexible layer 122. The flexible layer 122 is attached to the bottom surface of the base plate 121, and the first protrusion 125 is integrally formed with the flexible layer 122. The flexible layer 122 is made of rubber or hard sponge, which can prevent the film gripper 100 from damaging the film 30 when it comes into contact with the film 30.

[0032] In this embodiment, the first adsorption structure 123 is a second protrusion integrally formed with the flexible layer 122, and the bottom surface of the second protrusion is provided with a first adsorption hole; the second adsorption structure 124 is a second adsorption hole provided on the side wall of the base plate 121, and the base plate 121 is provided with a first air passage communicating with the first adsorption hole and a second air passage communicating with the second adsorption hole. Using the adsorption hole to adsorb the adhesive film 30 simplifies the structure of the film gripper 100. The first air passage and the second air passage are independent of each other, and the adsorption effect of the first adsorption hole and the second adsorption hole is controlled separately. In other embodiments, the first adsorption structure 123 and the second adsorption structure 124 are flexible suction cups.

[0033] In this embodiment, the movable plate 120 includes several movable sub-plates arranged in parallel. Dividing the movable plate 120 into multiple parts can reduce the processing accuracy and installation accuracy requirements of the movable plate 120.

[0034] like Figure 4 As shown, this utility model also provides a transfer device, including a film laying mechanism, a film supply mechanism 300, and an auxiliary film suction component 400. The film laying mechanism includes a drive mechanism, a mounting beam 200, and film grippers 100. The drive mechanism is driven to the mounting beam 200 to drive the mounting beam 200 to move vertically and horizontally. Multiple film grippers 100 are provided and linearly spaced on the mounting beam 200. The film supply mechanism 300 is located below the film laying mechanism. The drive mechanism can drive the mounting beam 200 to move, so that multiple film grippers 100 can move above the film supply mechanism 300 and simultaneously grab multiple sheets of adhesive film 30. The auxiliary film suction component 400 is used to cooperate with the film grippers 100 to fold up the two sides corresponding to the two long sides of the adhesive film 30, so that the bottom and side surfaces of the film grippers 100 respectively adsorb the middle area of ​​the adhesive film 30 and the folded side areas, ensuring that the adhesive film 30 will not fall off the film grippers 100 during the transfer process.

[0035] like Figure 5 The diagram illustrates the process of the first type of auxiliary film suction member 400 and film gripper 100 gripping the adhesive film 30 in this invention. In this embodiment, the auxiliary film suction member 400 includes multiple spaced support rods 410, which are positioned above the film supply mechanism 300. Multiple film grippers 100 can simultaneously move into the multiple gaps formed by the support rods 410. The film supply mechanism 300 can be a synchronous belt 310 or a moving platform for conveying the adhesive film 30. When the film gripper 100 moves between the support rods 410, the side of the film gripper 100 faces the support rod 410, and the distance between the side of the film gripper 100 and the support rod 410 is slightly greater than the thickness of the adhesive film 30.

[0036] In this embodiment, the process of the film gripper 100 adsorbing the adhesive film 30 is as follows: First, as shown in Figure (a), the adhesive film 30 is located on the film supply mechanism 300. The film gripper 100 moves down through the gap of the support rod 410. After the bottom surface of the film gripper 100 contacts the adhesive film 30, it adsorbs the middle part of the adhesive film 30. Then, as shown in Figure (b), the film gripper 100 moves up again through the gap of the support rod 410 and moves to the top of the support rod 410. When the adhesive film 30 passes the support rod 410, its two sides bend downward under the action of the support rod 410. After the adhesive film 30 moves to the top of the support rod 410, its two sides will rebound, and the adhesive film 30 basically returns to a flat state. Finally, as shown in Figure (c), the film gripper 100 moves down again. After the two sides of the adhesive film 30 contact the support rod 410, they fold upward and stick to the side of the film gripper 100 and are adsorbed by it. In this embodiment, the cross-section of the support rod 410 is circular, which can prevent the adhesive film 30 from being damaged when it comes into contact with the support rod 410.

[0037] like Figure 6 The diagram illustrates the process of the second auxiliary film suction component 400 and the film gripper 100 gripping the adhesive film 30 in this invention. In this embodiment, the film supply mechanism 300 is provided with multiple grooves at intervals, and each groove is provided with a liftable lifting rod 420. When the lifting rod 420 is in the high position, the top of the lifting rod 420 extends out of the groove, and multiple film grippers 100 can move simultaneously into the multiple gaps formed by the multiple lifting rods 420. The film supply mechanism 300 is a film carrier platform 320 that carries the adhesive film 30. When the lifting rod 420 is in the low position, the top surface of the lifting rod 420 is flush with the support surface of the film carrier platform 320. When the lifting rod 420 is in the high position, the top surface of the lifting rod 420 is higher than the support surface of the film carrier platform 320. After multiple adhesive films 30 are laid on the film carrier platform 320, the top surface of the lifting rod 420 faces the areas on both sides of the adhesive film 30. When the lifting rod 420 is raised and the film gripper 100 moves between the lifting rod 420, the side of the film gripper 100 faces the lifting rod 420, and the distance between the side of the film gripper 100 and the lifting rod 420 is slightly greater than the thickness of the film 30.

[0038] In this embodiment, the process of the film gripper 100 adsorbing the adhesive film 30 is as follows: First, as shown in Figure (d), the adhesive film 30 is located on the film carrier stage 320, and the bottom surface of the film gripper 100 contacts the adhesive film 30; then, as shown in Figure (e), the lifting rod 420 rises, causing the two sides of the adhesive film 30 to fold upwards and adhere to the sides of the film gripper 100 for adsorption. In this embodiment, the top of the lifting rod 420 near the film gripper 100 is rounded to prevent damage to the adhesive film 30 when it comes into contact with the lifting rod 420.

[0039] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the present utility model.
