DETAILED DESCRIPTION

[0019] Following make the embodiments of the present application specific examples, those skilled in the art can easily understand the advantages and effects of the present application from the disclosure of the specification. The present application can also be implemented or applied by another different specific implementation, and the details in the specification can be modified or changed based on different views and applications without departing from the spirit of the present application. It should be noted that the following examples and features in the examples can be combined with each other without conflict.

[0020] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings and examples.

[0021] The embodiments of the present application provide a lengthening piece applied to a string welding machine, as shown in Figure 1 and Figure 2 The lengthening piece applied to the string welding machine includes a lengthening plate 100, a connecting assembly 200, and a suction nozzle 300. The lengthening plate 100 is detachably mounted to a bearing end 410 of the string welding machine 400 through the connecting assembly 200. The suction nozzle 300 is arranged at the upper end of the lengthening plate 100. The suction nozzle 300 is connected to a gas pump 600 through a pipeline 500.

[0022] In the embodiments, in order to make the string welding machine 400 applicable to more battery string types, a lengthening plate 100 is detachably assembled at the bearing end 410 of the string welding machine 400 through the connecting assembly 200, so that the string welding machine 400 can bear a longer battery string. Moreover, in the face of the problem that the lengthening part of the suction string vacuum air path will not be able to suck the battery string due to insufficient vacuum, the suction nozzle 300 is arranged at the upper end of the lengthening plate 100 to increase the suction force on the lengthening section of the newly applicable battery string type, so as to ensure that the battery string can be normally sucked.

[0023] In some embodiments, the specific structure of the connecting assembly 200 is provided. As shown in Figure 2 The connecting assembly 200 includes a first mounting plate 210, a second mounting plate 220, and an assembly component 230. The first mounting plate 210 is fixed to the bottom of the bearing end 410. The second mounting plate 220 is fixed to the bottom of the lengthening plate 100. First and second through holes 211 and 221 are respectively arranged on the first and second mounting plates 210 and 220. The assembly component 230 fixes the first and second mounting plates 210 and 220 through the first and second through holes 211 and 221, so as to mount the lengthening plate 100 to the bearing end 410.

[0024] Exemplarily, the assembling component 230 includes a screw rod 231, a nut 232 and a gasket 233. One end of the screw rod 231 passes through the first through hole 211 and the second through hole 221 in sequence, and the screw rod 231 is fixed by the nut 232 and the gasket 233 to fix the first mounting plate 210 and the second mounting plate 220.

[0025] Specifically, the nut 232 matches the threaded end of the screw rod 231, for example, the nut 232 has an internal thread, and the end of the screw rod 231 is an external thread matched with the internal thread. The nut 232 is fixed by abutting against one side of the second mounting plate 220 through the gasket 233, so as to fix the first mounting plate 210 and the second mounting plate 220. Since the first mounting plate 210 and the second mounting plate 220 are fixed, the extension plate 100 is fixed on the bearing end 410 of the stringer 400, so that the bearing end 410 of the stringer 400 can bear a battery string with a longer length, so as to adapt to more types of battery strings, thereby reducing the production and operation cost on the basis of the original equipment, and greatly improving the machine utilization.

[0026] In the embodiment, in the actual production process, for example, a batch of orders is newly received, and the original stringer cannot adapt to the type of battery string required by the order. The extension plate 210 with a set length can be added to the bearing end of the original stringer through the assembling component 230. After the batch of orders is completed, the type of battery string required by the newly received order is exactly the type adapted by the original stringer, and the newly added extension plate 210 can be removed, so that one stringer device can be used flexibly.

[0027] In some embodiments, as shown in Figure 3 The suction nozzles 300 are provided in multiple numbers, and each suction nozzle 300 is connected to a main pipeline 520 through a branch pipeline 510. The main pipeline 520 is connected to the air pump 600.

[0028] In the embodiment, the air pump 600 can be a vacuum pump provided in the original stringer. When the suction nozzles 300 are added, the pipeline is improved to ensure that the suction force of the newly added suction nozzles and the original suction nozzles remains consistent, so as to effectively suck the newly added type of battery string. Specifically, the air pump 600 transmits power through the main pipeline 520. A plurality of branch pipelines 510 are arranged on the main pipeline 520. Some of the branch pipelines 510 are connected to the newly added suction nozzles 300, and the remaining branch pipelines 510 are connected to the original suction nozzles. In this way, after the vacuum reaches the standard value, the suction and the bearing end of the whole battery string will remain consistent in the moving position, so as to meet the normal tab lifting and string correction functions.

[0029] In some embodiments, the length of the lengthened plate 100 is 100-200 mm. The specific length of the lengthened plate 100 is determined according to the battery string to which the adaptation version is to be added.

[0030] Exemplarily, taking the DH150-F stacker as an example, the welding size of the DH150-F stacker is only applicable to the 144 version and the 108 version. In order to enable it to adapt to the 120 version, as shown in Figure 1 , a lengthened piece with a length of 135 mm is added to the DH150-F stacker, the gas path end is divided into a gas path to a separate suction nozzle through a connecting block, and the original and the added suction nozzles all use the 108 version special suction nozzle. After calibrating the parameters of each point, automatic welding is realized. The stringer after this modification can be compatible with the 120 version and the 108 version, meeting the equipment demand of component version change. After the modification of the DH150-F stacker, the position of the entire battery string is calculated by the camera, and then welding is performed after correction and adjustment. The automatic production of the entire component product is realized. At present, the DH150-F can be compatible with three different versions of 144, 120 and 108 (compatible with 144 and 108 versions without adding a lengthened piece, and compatible with 120 and 108 versions by adding a lengthened piece), and can be quickly switched in a short time. On the basis of the original equipment, the production and operation cost is reduced, thereby greatly improving the machine utilization rate.

[0031] The embodiments of the present application also provide a stringer, as shown in Figure 1 , the stringer 400 comprises a bearing end 410, and the bearing end 410 is provided with a lengthened piece applied to the stringer according to any one of the embodiments of the present application.

[0032] It should be noted that the stringer 400 generally has a plurality of bearing ends 410, and the lengthened piece can be added only on one bearing end 410 as shown in Figure 1 , or can be added on part or all of the bearing ends 410.

[0033] The above embodiments are only used to illustrate the present application, and are not intended to limit the present application. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application, therefore all equivalent technical solutions also belong to the scope of the present application, and the patent protection scope of the present application should be defined by the claims.
