[0043] The light-transmitting plate is placed on the light-transmitting plate conveying device 5 and conveyed by the light-transmitting plate conveying device 5. The battery string arrangement device arranges the battery strings to be typeset at the previous working station on the light-transmitting plate to form a battery string assembly. The battery string assembly includes a plurality of battery string groups arranged in parallel, wherein each battery string group includes two battery strings arranged oppositely along the length direction of the battery string;

[0044] The battery string assembly lifting device 6 lifts the battery string assembly from the light-transmitting plate, and the bus bar feeding device places a bus bar below the lifted battery string assembly;

[0045] The welding device welds the stacked battery string assembly and the bus bar;

[0046] The battery string assembly lifting device 6 places the welded battery string assembly on the light-transmitting plate, and the light-transmitting plate conveying device conveys the light-transmitting plate to the next working station.

[0047] Wherein, the light-transmitting plate is used to manufacture a battery module together with the battery string in subsequent processes. This 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 device provided by the present invention integrates the functions of typesetting and welding of battery strings, has a high degree of automation, can effectively improve production efficiency, and occupies a small space, saving costs.

[0049] The following will Figure 1 and Figure 2 show a specific embodiment to detail the battery string arrangement and welding device provided by the present invention.

[0050] In this embodiment, the battery string arrangement and welding device 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 translates it and then places it on the light-transmitting plate. Herein, the "translation" mentioned in this application refers to moving without rotation, and it can include moving in the horizontal direction and moving in the vertical direction.

[0052] In this embodiment, the battery string feeding device 1 includes a bracket and a conveyor belt provided on the bracket for carrying the 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 Figure 1 shown, this battery string feeding device 1 (which 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) moves to the lower part of the first battery string grasping device 2 after carrying the battery strings, and the first battery string grasping device 2 picks up the battery strings. 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 strings.

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

[0055] In this embodiment, the length direction of the battery string provided by the battery string feeding device 1 is perpendicular to the length direction of the battery string 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 light-transmitting plate. 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 onto the light-transmitting plate without rotation.

[0056] When the battery string assembly on the light-transmitting plate 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 7, and the bypass bus bar feeding device 7 lays a bypass bus bar on the intermediate carrier plate 3, or the bypass bus bar feeding device 7 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 onto the light-transmitting plate of the light-transmitting plate conveying device 5.

[0058] Specifically, the bypass bus bar feeding device 7 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 arranged adjacent to it onto the light-transmitting plate.

[0059] In this embodiment, preferably, the battery string arranging 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, and the cutting part cuts the welding tape at the end of the battery string to be cut after regularization. In this way, after the relative positions of the two battery strings in each battery string group and the length of the welding tape at the end of the battery string meet the required requirements, they are transported to the light-transmitting plate of the light-transmitting plate conveying device 5.

[0060] Preferably, the light-transmitting plate is arranged to move out from the lower side of the intermediate carrier plate 3 towards the subsequent working station. Every time the light-transmitting plate moves out a preset distance, the second battery string gripping device 4 places a battery string on the light-transmitting plate.

[0061] Specifically, the light-transmitting plate conveying device 5 can first enter below the battery string feeding device 1 and then gradually move towards the subsequent process. When the light-transmitting plate conveying device 5 gradually moves out from below the intermediate carrier plate 3, the second battery string grasping device 4 places the battery string group grasped from the intermediate carrier plate 3 onto the light-transmitting plate. Every time the light-transmitting plate moves out a preset distance from below the intermediate carrier plate 3, the second battery string grasping device 4 releases the battery string that has moved out. This can reduce the moving distance when the second battery string grasping device 4 transports the battery string group, thereby facilitating the improvement of production efficiency. It can be understood that the light-transmitting plate conveying device 5 is not limited to moving from below the battery string feeding device 1 towards the subsequent process. It can also first place the light-transmitting plate conveying device 5 below the intermediate carrier plate 3 and then further move towards the subsequent process.

[0062] After arranging the battery string components on the light-transmitting plate, the battery string component lifting device 6 lifts the battery string components from the light-transmitting plate to the welding station. The bus bar feeding device places the bus bar at the welding station below the lifted battery string components. The welding device welds the battery string components and the bus bar stacked at the welding station.

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

[0064] After the battery string component lifting device 6 lifts the battery string components, the first bus bar feeding device, the second bus bar feeding device, and the third bus bar feeding device stack the bus bars at the welding station below the battery string components respectively. Then the battery string component lifting device 6 lowers the lifted battery string components, and / or raises the first bus bar, the second bus bar, and the third bus bar, so that the battery string components and the bus bars are stacked together. The welding device can then weld the stacked battery string components and the bus bars. After welding is completed, the battery string component lifting device 6 places the welded battery string components onto the light-transmitting plate of the light-transmitting plate conveying device 5 and transports them to the next process.

[0065] In another embodiment, it can also be set that after the battery string component lifting device 6 lifts the battery string component from the light-transmitting plate, the bus bar feeding device places a bus bar on the light-transmitting plate below the lifted battery string component, the battery string component lifting device 6 stacks the battery string component on the bus bar, and the welding device welds the battery string component and the bus bar stacked on the light-transmitting plate.

[0066] According to another aspect of the present invention, there is also provided a method for arranging and welding battery strings. The method uses the battery string arranging and welding equipment as described above. The method for arranging and welding battery strings includes:

[0067] Place the light-transmitting plate on the light-transmitting plate conveying device 5 for conveying, arrange the battery strings to be typeset in the previous process on the light-transmitting plate to form a battery string component. The battery string component includes a plurality of battery string groups arranged in parallel, where each battery string group includes two battery strings arranged oppositely along the length direction of the battery string;

[0068] Lift the battery string component from the light-transmitting plate and place a bus bar below the lifted battery string component;

[0069] Weld the stacked battery string component and the bus bar;

[0070] Place the welded battery string component on the light-transmitting plate, and the light-transmitting plate conveying device 5 conveys the light-transmitting plate to the next process.

[0071] Among them, placing the light-transmitting plate on the light-transmitting plate conveying device 5 for conveying and arranging the battery strings to be typeset in the previous process on the light-transmitting plate includes: the light-transmitting plate conveying device 5 drives the light-transmitting plate to move step by step. Each time the light-transmitting plate moves step by step by a preset distance, a battery string is placed on the light-transmitting plate.

[0072] More specifically, arranging the battery strings to be typeset in the previous process on the light-transmitting plate includes:

[0073] Use the first battery string gripping device 2 to pick up a string of battery strings to be typeset, and then rotate the first battery string gripping device 2 to pick up another string of battery strings to be typeset, so that the two battery strings picked up by the first battery string gripping device are in opposite directions;

[0074] Synchronously rotate the two strings of battery strings in opposite directions by 90° and place them on the intermediate carrier plate 3;

[0075] Use the light-transmitting plate conveying device 5 to convey the light-transmitting plate in the direction of the next process;

[0076] When the light-transmitting plate moves backward a predetermined distance each time from below the middle carrier plate 3 towards the subsequent working station, at least one set of battery string groups arranged on the middle carrier plate 3 is picked up by the second battery string gripping device 4 and translated and placed on the light-transmitting plate.

[0077] Wherein, after the battery strings are placed on the middle carrier plate 3, the method may further include: regularizing the positions of the battery strings carried on the middle carrier plate 3, and cutting the welding tapes at the ends of the carried battery strings through the cutting part.

[0078] Of course, it is also possible to directly arrange the relative positions of the two battery strings in each battery string group accurately on the middle carrier plate 3, and the length of the welding tapes at the ends of the battery strings meets the requirements, and the second battery string gripping device 4 directly transports the battery string groups on the middle carrier plate 3 to the light-transmitting plate.

[0079] The conveying the light-transmitting plate on the light-transmitting plate conveying device 5 includes: a plurality of the light-transmitting plates are provided, and the light-transmitting plate conveying device 5 conveys the plurality of light-transmitting plates in sequence. Each time a battery string assembly is arranged and welded, one light-transmitting plate is conveyed correspondingly.

[0080] Other aspects of the battery string arranging and welding method can refer to the specific process of arranging and welding the battery string assembly by using the battery string arranging and welding equipment described above.

[0081] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto.
