[0002] In order to improve the arrangement efficiency of battery wafers, in the related art, the bearing surface of the wafer transfer mechanism of the string welding machine is lengthened along the stringing direction, so that the wafer transfer mechanism can carry more battery wafers to improve the arrangement efficiency of battery wafers. However, the increase in the size of the wafer transfer mechanism will easily cause interference with other components. To solve the interference problem, the overall specification size of the string welding equipment also needs to be increased, which in turn leads to the string welding equipment occupying a larger space area in the factory environment. Content of the Utility Model

[0003] The purpose of the utility model is to provide a back-contact battery string stringing device to solve the problems put forward in the above background technique.

The wafer transfer surfaces of the first lifting wafer transfer table and the second lifting wafer transfer table are arranged at intervals in the vertical direction. Along the stringing direction, the first lifting wafer transfer table and the second lifting wafer transfer table are both independently movable on the bearing mechanism. The wafer transfer surfaces of the first lifting wafer transfer table and the second lifting wafer transfer table can independently move up and down relative to the bearing surface of the bearing mechanism, wherein the vertical direction is perpendicular to the stringing direction.

[0006] Preferably, the wafer carrier includes a support frame and a bearing member. There are two bearing members which are arranged at intervals on the support frame. A transport channel is formed between the two bearing members. The first lifting wafer transfer table and the second lifting wafer transfer table can both move in the transport channel.

[0007] Preferably, a plurality of adsorption holes are arranged at intervals on the bearing member.

[0011] The technical solution adopted in this application can achieve the following beneficial effects:

[0012] In a back-contact battery string row string device disclosed in this application, since the transfer surfaces of the first lifting and transferring table and the second lifting and transferring table are spaced apart in the vertical direction, when the first lifting and transferring table carries a plurality of battery wafers and moves to the carrying mechanism, the second lifting and transferring table is lifted to make its transfer surface flush with the transfer surface of the first lifting and transferring table, and the second lifting and transferring table starts to carry a plurality of battery wafers, alternately and reciprocally in sequence.

At the same time, by setting the transfer surfaces of the first lifting and transferring table and the second lifting and transferring table to be spaced apart in the vertical direction, the space occupied along the row string direction is reduced, and the space is reasonably and effectively utilized, thereby avoiding interference with other components of the string welding machine due to increasing the size of only one first lifting and transferring table to carry more battery wafers.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0022] Such as Figures 1 to 3As shown in the figure, the present application discloses a back-contact battery string series connection device. The disclosed back-contact battery string series connection device includes a bearing mechanism 100, a first lifting and sheet-transferring table, and a second lifting and sheet-transferring table. Among them, the bearing mechanism 100 is used to bear a plurality of battery cells arranged at a preset interval, and both the first lifting and sheet-transferring table and the second lifting and sheet-transferring table are used to receive a plurality of battery cells and transfer them onto the bearing mechanism 100.

[0023] Specifically, the sheet-transferring surfaces of the first lifting and sheet-transferring table and the second lifting and sheet-transferring table are arranged at intervals in the vertical direction. In the series connection direction, the first lifting and sheet-transferring table and the second lifting and sheet-transferring table are movably arranged on the bearing mechanism 100 independently. The sheet-transferring surfaces of the first lifting and sheet-transferring table and the second lifting and sheet-transferring table can move up and down relative to the bearing surface of the bearing mechanism 100 independently. Among them, the vertical direction is perpendicular to the series connection direction.

[0024] During the use of the back-contact battery string series connection device, since the sheet-transferring surfaces of the first lifting and sheet-transferring table and the second lifting and sheet-transferring table are arranged at intervals in the vertical direction, when the first lifting and sheet-transferring table bears a plurality of battery cells and moves to the bearing mechanism 100, the second lifting and sheet-transferring table is lifted to make its sheet-transferring surface flush with the sheet-transferring surface of the first lifting and sheet-transferring table, and the second lifting and sheet-transferring table starts to bear a plurality of battery cells. This process alternates and repeats in sequence, so that the sheet-transferring time of the first lifting and sheet-transferring table overlaps with the cell-carrying time of the second lifting and sheet-transferring table, thereby achieving the arrangement of more battery cells on the bearing mechanism 100 in a shorter time.

[0025] In the above structure, the first lifting and sheet-transferring table and the second lifting and sheet-transferring table alternately transfer battery cells, which also improves the arrangement efficiency of the battery cells on the bearing mechanism 100. At the same time, by arranging the sheet-transferring surfaces of the first lifting and sheet-transferring table and the second lifting and sheet-transferring table at intervals in the vertical direction, the space occupied in the series connection direction is reduced, and the space is reasonably and effectively utilized, thereby avoiding interference with other components of the string welding machine due to increasing the size of only one first lifting and sheet-transferring table to transfer more battery cells.

[0026] In the embodiment of the present application, the bearing mechanism 100 may include a base 110 and a cell-carrying table 120. Specifically, the cell-carrying table 120 and the base 110 are arranged at intervals up and down.

[0028] In an alternative solution, the carrier stage 120 may be provided with an installation space, and a part of the base 110 is located in the installation space to prevent the base 110 from occupying too much space and interfering with other components of the string welding machine.

[0029] In another alternative solution, the carrier stage 120 may include a support frame 121 and a carrier 122. Specifically, there are two carriers 122 which are spaced apart on the support frame 121, and a transport channel is formed between the two carriers 122. Both the first lifting and transporting stage and the second lifting and transporting stage can move in the transport channel. By supporting the carrier 122 through the support frame 121, a transport channel is formed between the two carriers 122, which is convenient for the first lifting and transporting stage and the second lifting and transporting stage to return to the initial position of carrying the battery wafers through the transport channel when alternately transporting wafers, so as to realize the rational use of space.

[0030] In a further technical solution, a plurality of adsorption holes may be provided on the carrier 122 at intervals, and the plurality of adsorption holes can correspondingly adsorb a plurality of arranged battery wafers to prevent the plurality of battery wafers from shifting.

Of course, both the second driving component 220 and the second driving component 220 can be servo motors 222, telescopic cylinders, electric cylinders, etc., and the present application does not make any restrictions on this.
