[0002] Currently, in the process of stringing grid-less solar cells, the methods for fixing the solder ribbons in the ribbon bundle to the surface of the solar cell include welding, adhesive bonding, and film bonding. Because welding is costly and adhesive bonding has poor conductivity, film bonding is widely favored in the industry for connecting the solder ribbons to the solar cell.

[0003] In the existing technology, a coating device is usually used to coat a single solar cell, and the coating efficiency needs to be further improved. If two coating devices are used to coat two solar cells at the same time, although the coating efficiency is improved, the manufacturing cost is high and the space occupied is large. Summary of the Invention

[0004] The purpose of this invention is to provide a coating device and a battery cell stringing equipment that can simultaneously coat two battery cells with high coating efficiency, low manufacturing cost, and small space occupation.

[0005] To achieve this objective, the present invention adopts the following technical solution: A laminating device includes a frame, a lifting seat slidably connected to the frame, a receiving frame rotatably mounted on the lifting seat, the receiving frame having multiple outer sides, and two receiving platforms slidably mounted on each outer side, each receiving platform having a plurality of vacuum adsorption grooves for adsorbing and fixing adhesive film; an elastic reset member is provided between the receiving platform and the receiving frame. A spacing mechanism is provided inside the receiving frame. The spacing mechanism is connected to each of the receiving platforms. Two receiving platforms located on the same side can slide back to back after overcoming the elastic force of the elastic reset member due to the influence of the spacing mechanism. The lifting seat is connected to a lifting drive mechanism that drives it to slide up and down. The receiving frame is connected to a rotary drive mechanism, which can drive the receiving frame to rotate, so that the two receiving platforms on the same outer side of the receiving frame can cycle between the receiving station and the coating station.

[0006] Furthermore, the pitching mechanism includes a camshaft located within the receiving frame and a first cam and a second cam sleeved on the camshaft and forming an angle along the circumference; the camshaft is connected to the lifting seat, and the central axis of the camshaft is collinear with the rotation center axis of the receiving frame; the first cam rolls or slides in contact with a plurality of first pitching adjustment rods, and the second cam rolls in contact with a plurality of second pitching adjustment rods; of the two receiving platforms located on the same surface, one receiving platform is connected to a first pitching adjustment rod, and the other receiving platform is connected to a second pitching adjustment rod.

[0007] Furthermore, when the two receiving platforms located on the same side rotate to the receiving station with the receiving frame, the distance between the position where the first pitch adjustment rod contacts the first cam and the position where the second pitch adjustment rod contacts the second cam is minimized; When the two receiving platforms located on the same side rotate to the film coating station with the receiving frame, the distance between the position where the first pitch adjustment rod contacts the first cam and the position where the second pitch adjustment rod contacts the second cam is at its maximum.

[0008] Furthermore, both the first and second pitch adjustment rods are rotatably connected to rollers, and the rollers are in rolling contact with the first or second cam.

[0014] A battery cell stringing device, the battery cell stringing device including the above-mentioned coating device.

[0015] The beneficial effects of this utility model are as follows: This application utilizes a rotary drive mechanism to drive the receiving frame to rotate, causing the two receiving platforms on the same outer side of the receiving frame to circulate between the receiving station and the coating station. During the rotation from the receiving station to the coating station, the two receiving platforms, influenced by the spacing mechanism, overcome the elastic force of the elastic reset member and slide in opposite directions, thereby achieving the adjustment of the spacing between the two sets of adhesive films. Upon reaching the coating station, a lifting drive mechanism drives the lifting seat and the receiving frame to move downwards together, thereby attaching the two sets of adhesive films, after adjustment, to the two battery cells. During the rotation from the coating station to the receiving station, the two receiving platforms move towards each other and reset under the elastic force of the elastic reset member, facilitating the next round of coating operations. This coating device achieves simultaneous coating of two battery cells, resulting in high coating efficiency, low manufacturing cost, and small space occupation. Attached Figure Description

[0026] In this embodiment, as Figure 2 and 6 As shown, the top surface of the receiving platform 3 is provided with a number of protrusions 31 at intervals along the direction perpendicular to its sliding. The top surface of the protrusions 31 is provided with a vacuum adsorption groove 311, and a number of ventilation holes 312 are provided at intervals in the vacuum adsorption groove 311.

[0027] In this embodiment, as Figure 1 As shown, the rotary drive mechanism 6 includes a drive gear 61, a driven gear 62, a synchronous belt, and a motor 63. The motor 63 is mounted on the lifting base 11. The drive gear 61 is coaxially connected to the output end of the motor 63. The driven gear is coaxially connected to the rotating shaft of the receiving frame 2. The synchronous belt drives the drive gear 61 and the driven gear 62.

[0028] like Figure 2 and 3As shown, the pitching mechanism 4 includes a camshaft 43 located within the receiving frame 2 and a first cam 41 and a second cam 42 sleeved on the camshaft 43 and forming an angle along the circumference; wherein, the camshaft 43 is connected to the lifting seat 11, and the central axis of the camshaft 43 is collinear with the rotation center axis of the receiving frame 2; the first cam 41 has rolling or sliding contact with several first pitching adjustment rods 44, and the second cam 42 has rolling contact with several second pitching adjustment rods 45; among the two receiving platforms 3 located on the same surface, one receiving platform 3 is connected to a first pitching adjustment rod 44, and the other receiving platform 3 is connected to a second pitching adjustment rod 45.

[0029] Among them, when the two receiving platforms 3 located on the same side rotate with the receiving frame 2 to the receiving station, the distance between the position of the first spacing adjustment rod 44 contacting the first cam 41 and the position of the second spacing adjustment rod 45 contacting the second cam 42 is the smallest; when the two receiving platforms 3 located on the same side rotate with the receiving frame 2 to the film coating station, the distance between the position of the first spacing adjustment rod 44 contacting the first cam 41 and the position of the second spacing adjustment rod 45 contacting the second cam 42 is the largest.

Since the first spacing adjustment rod 44 is in rolling contact with the first cam 41 and the second spacing adjustment rod 45 is in rolling contact with the second cam, the two receiving platforms 3 with the adhesive film adsorbed and fixed move in opposite directions after overcoming the elastic force of the elastic reset member, thereby realizing the spacing adjustment of the adhesive film. After reaching the coating station, the lifting drive mechanism 5 drives the lifting seat 11 to move downward, so that the two sets of adhesive films after the spacing adjustment move downward with the receiving frame 2, thereby attaching the two sets of adhesive films to the two battery cells.
