[0043] The battery string arrangement device arranges the battery strings to be typeset at the previous working station on the battery string component carrying device 5 to form a battery string component, and the battery string component includes a plurality of battery string groups arranged in parallel, wherein each of the battery string groups includes two battery strings arranged oppositely along the length direction of the battery string;

[0047] Among them, the light-transmitting plate is used to manufacture a battery module together with a battery string in subsequent processes. The light-transmitting plate is required to have a certain light transmittance, and the commonly used material is glass.

[0048] The battery string arrangement and welding equipment provided by the present invention integrates the functions of battery string layout and welding, has a high degree of automation, can effectively improve production efficiency, and occupies a small space, saving costs.

[0049] The following is based on Figure 1 and Figure 2 A specific embodiment shown in detail describes the battery string arrangement and welding equipment provided by the present invention.

[0050] In this embodiment, the battery string arrangement and welding equipment further includes a battery string feeding device 1, and the battery string feeding device 1 carries at least two battery strings arranged in the same direction;

[0051] The battery string arrangement device includes: two first battery string grasping devices 2, an intermediate carrier plate 3, and a second battery string grasping device 4. Each first battery string grasping device 2 includes two suction mechanisms. After one suction mechanism of the first battery string grasping device 2 sucks a battery string from the battery string feeding device 1, the first battery string grasping device 2 rotates 180°, and then the other suction mechanism sucks another battery string from the battery string feeding device 1. The first battery string grasping device 2 places the two sucked battery strings on the intermediate carrier plate 3; the battery strings placed on the intermediate carrier plate 3 by the two first battery string grasping devices 2 are arranged oppositely, and the two oppositely arranged battery strings form a battery string group; the second battery string grasping device 4 picks up at least one battery string group from the intermediate carrier plate 3 and places it on the battery string module carrying device 5 after translation. Among them, the "translation" mentioned in this application refers to non-rotational movement, which can include horizontal movement and vertical movement.

[0052] In this embodiment, the battery string feeding device 1 includes a bracket and a conveyor belt provided on the bracket for carrying battery strings;

[0053] Among them, the battery string feeding device 1 is arranged to be movable along a direction perpendicular to the conveying direction of the conveyor belt. As shown in Figure 1 , after the battery string feeding device 1 carries a battery string (the battery string feeding device 1 can be arranged in the subsequent process of the battery string production equipment to receive the battery strings produced by the battery string production equipment), it moves along the arrow direction to the lower part of the first battery string grasping device 2, and the first battery string grasping device 2 picks up the battery string. Of course, it can also be arranged that the first battery string grasping device 2 can move to the upper part of the battery string feeding device 1 to grasp the battery string.

[0054] Generally, the battery strings on the battery string feeding device 1 are stacked and arranged in the same direction. However, in the battery string assembly to be arranged, two adjacent battery strings in the width direction of the battery string are in opposite directions. Therefore, after one suction mechanism of the first battery string gripping device 2 adsorbs a battery string, the other suction mechanism needs to rotate 180 degrees to adsorb the battery string, that is, the battery strings adsorbed by the two suction mechanisms are in opposite directions. The two first battery string gripping devices 2 are placed on the intermediate carrier plate 3 with the battery strings arranged oppositely to form two battery string groups.

[0055] In this embodiment, the length direction of the battery strings provided by the battery string feeding device 1 is perpendicular to the length direction of the battery strings to be arranged on the intermediate carrier plate 3. Therefore, after the first battery string gripping device 2 sucks two battery strings from the battery string feeding device 1, it rotates 90°, and arranges the rotated battery strings on the intermediate carrier plate 3. The arrangement direction of the battery strings on the intermediate carrier plate 3 is the same as the arrangement direction of the battery strings on the battery string assembly carrying device 5. In this way, the second battery string gripping device 4 picks up at least one battery string group from the intermediate carrier plate 3 and directly translates the adsorbed battery string group to the battery string assembly carrying device 5 without rotation.

[0056] When the battery string assembly on the battery string assembly carrying device 5 includes an odd number of parallel battery string groups, it is necessary to weld a bypass bus bar on the battery string assembly. Therefore, the bus bar feeding device further includes a bypass bus bar feeding device 84, and the bypass bus bar feeding device 84 lays a bypass bus bar on the intermediate carrier plate 3, or the bypass bus bar feeding device 84 provides the bypass bus bar to a position close to the intermediate carrier plate 3.

[0057] The second battery string gripping device 4 is also used to synchronously translate and place the bypass bus bar and a battery string group that needs to be welded with the bypass bus bar on the battery string assembly carrying device 5.

[0058] Specifically, the bypass bus bar feeding device 84 pulls and cuts the bus bar to form a bypass bus bar. The bypass bus bar can be placed on the intermediate carrier plate 3 or at a position close to the intermediate carrier plate 3 so that the bypass bus bar is arranged adjacent to a battery string group on the intermediate carrier plate 3. In this way, the second battery string gripper 4 can grip and place the bypass bus bar and the battery string group adjacent to it on the battery string assembly carrying device 5.

[0059] In this embodiment, preferably, the battery string arrangement device further includes a first detection device and a cutting part. The first detection device obtains the position information of the battery strings on the intermediate carrier plate 3. The intermediate carrier plate 3 regularizes the battery strings according to the position information. The cutting part cuts the welding tapes at the ends of the regularized battery strings to be cut. In this way, after the relative positions of the two battery strings in each battery string group and the lengths of the welding tapes at the ends of the battery strings meet the required standards, they are transported to the battery string assembly carrier device 5.

[0060] In this embodiment, preferably, the battery string assembly carrier device 5 includes independent carrier platforms 51, and each carrier platform 51 carries a string of battery strings arranged by the battery string arrangement device.

[0061] The battery string arrangement device further includes a second detection device. The second detection device obtains the position information of the battery strings on the battery string assembly carrier device 5. Each carrier platform 51 regularizes the carried battery strings according to the position information obtained by the second detection device.

[0062] After the battery string arrangement device arranges the battery strings on the battery string assembly carrier device 5 and each carrier platform has regularized the positions of the battery strings, the battery string assembly lifting device 6 lifts the battery string assembly from the battery string assembly carrier device 5 to the welding station. The bus bar feeding device places a bus bar at the welding station below the lifted battery string assembly. The welding device welds the battery string assembly and the bus bar stacked at the welding station.

[0063] Specifically, the bus bar feeding device includes a first bus bar feeding device 81 for providing a first bus bar, a second bus bar feeding device 82 for providing a second bus bar, and a third bus bar feeding device 83 for providing a third bus bar. The first bus bar and the second bus bar are respectively stacked at opposite ends of the battery string assembly and perpendicular to the length direction of the battery string. The third bus bar is stacked at the middle position of the battery string assembly and perpendicular to the length direction of the battery string.

[0064] After the battery string assembly lifting device 6 lifts the battery string assembly, the first bus bar feeding device 81, the second bus bar feeding device 82, and the third bus bar feeding device 83 stack the bus bars at the welding station below the battery string assembly respectively. Then the battery string assembly lifting device 6 lowers the lifted battery string assembly, and / or the first bus bar, the second bus bar, and the third bus bar are lifted, so that the battery string assembly and each bus bar are stacked together, and the welding device can weld the stacked battery string assembly and the bus bar.

[0065] In another embodiment, the welding process can also be set as follows: the battery string assembly lifting device 6 lifts the battery string assembly from the battery string assembly carrying device 5, the bus bar feeding device places a bus bar on the battery string assembly carrying device 5 below the lifted battery string assembly, the battery string assembly lifting device 6 places the battery string assembly on the bus bar, and the welding device welds the battery string assembly and the bus bar stacked on the battery string assembly carrying device 5.

[0066] After the welding of the battery string assembly is completed, the battery string assembly is transported by the battery string assembly lifting device 6 to a light-transmitting plate of the light-transmitting plate conveying device 7 located at the post-station of the welding device, and the conveying part of the light-transmitting plate conveying device 7 conveys the light-transmitting plate to the next station.
