Thus, the present application employs vacuum suction nozzle 23 to suck the cell aluminum case 20. Specifically, each adsorption component 2 is respectively used for sucking the cell aluminum shell 20, each adsorption component 2 has the same structure and comprises a vacuum generator 22 and a vacuum suction nozzle 23 which are connected with each other, and air is pumped by the vacuum generator 22 to generate negative pressure so that the vacuum suction nozzle 23 sucks the cell aluminum shell 20. It should be noted that, here, each adsorption component 2 may include a vacuum generator 22, so that the clamping of each adsorption component 2 does not affect each other, and when one vacuum generator 22 fails, the clamping of the other adsorption components 2 by the cell aluminum case 20 is not affected. Of course, for cost saving, only one vacuum generator 22 may be provided, one vacuum generator 22 being connected to each vacuum nozzle 23 of each suction module 2.

Through set up vacuum generator 22 and vacuum nozzle 23 on each absorption subassembly 2, every absorption subassembly 2 is all independent be used for adsorbing electric core aluminum shell 20, and the quantity of corresponding absorption subassembly 2 can adsorb a plurality of electric core aluminum shells 20 simultaneously, has improved transport and detection efficiency. And the vacuum adsorption mode is adopted, so that the surface of the cell aluminum shell 20 is not damaged.

Referring to fig. 2, in some embodiments, the connection base 21 includes a mounting plate 211 and a mounting bracket 212 coupled to the mounting plate 211, the mounting bracket 212 having mounting holes 2121 formed thereon, and the vacuum nozzle 23 is mounted to the mounting holes 2121.

Specifically, the air inlet end and the adsorption end of the vacuum suction nozzle 23 are respectively located at two sides of the mounting hole 2121, the air inlet end and the adsorption end are mutually communicated through a connecting section, the air inlet end is used for being connected with the vacuum generator 22, the adsorption end is used for adsorbing the cell aluminum shell 20, and the connecting section is clamped on the mounting hole 2121. The layout of the whole structure is designed more reasonably, and the vacuum air pipes communicated with the air inlet end and the vacuum generator 22 and the electric core aluminum shell 20 needing to be adsorbed are arranged on the two sides of the mounting frame 212, so that the position of the vacuum air pipe is easy to change, and the electric core aluminum shell 20 is prevented from being impacted due to the fact that the position of the vacuum air pipe moves when the electric core aluminum shell 20 is adsorbed, and the adsorption effect is influenced.

In some embodiments, the vacuum nozzles 23 and the mounting plate 211 are alternately arranged.

For example, when the number of the suction units 2 is two, there are two mounting plates 211 and two sets of vacuum nozzles 23, and at this time, the two sets of vacuum nozzles 23 and the two mounting plates 211 are alternately arranged, so that the design can be such that one mounting plate 211 is provided between the two sets of vacuum nozzles 23, and the interval between the two sets of vacuum nozzles 23 can be increased. If the two sets of vacuum suction nozzles 23 are arranged close to each other, that is, the two sets of vacuum suction nozzles 23 are arranged between the two mounting plates 211, if each set of vacuum suction nozzles 23 is used for independently sucking the cell aluminum casing 20, if the size of the sucked cell aluminum casing 20 is larger, the two cell aluminum casings 20 may collide with each other, and because the cell aluminum casing 20 is made of a softer material, the surface damage or other surface defects of the cell aluminum casing 20 are particularly easy to cause. Therefore, by alternately arranging the vacuum suction nozzles 23 and the mounting plate 211, the space between the two groups of vacuum suction nozzles 23 is increased, so that the vacuum suction device can be suitable for adsorbing the cell aluminum shell 20 with a larger size, and damage caused by collision between the cell aluminum shells 20 is avoided. Of course, when the number of the suction units 2 is two, two sets of vacuum nozzles 23 may be provided outside the two mounting plates 211, respectively.

For example, when the weight of the battery cell is large, more mounting frames 212 are required to mount more vacuum suction nozzles 23, so that the suction force is improved to suck the battery cell aluminum housing 20. When the size of the cell aluminum casing 20 is larger and the weight is not large, the interval of the mounting frame 212 can be set larger, so that the cell aluminum casing 20 can be adsorbed from each position of the cell aluminum casing 20, and the firm adsorption and no inclination of the cell aluminum casing 20 are ensured.

Through can dismantle the mounting bracket 212 with mounting panel 211 and be connected, can be according to the size or the quantity of electric core aluminum hull 20, rationally set up the quantity of mounting bracket 212 and the interval of mounting bracket 212, ensure firmly adsorbing electric core aluminum hull 20. And the detachable connection is arranged, so that the installation and the detachment are very convenient, and the convenience of operation is improved.

In some embodiments, the number of vacuum nozzles 23 is 4-6.

Regarding the number of vacuum nozzles 23, it is possible to set according to actual needs. More vacuum suction nozzles 23 mean a larger vacuum suction force, which can suck the cell aluminum case 20 with larger size and weight, but also means that the size of the suction assembly 2 is larger, and a more powerful vacuum generator 22 is required, increasing the volume and manufacturing cost of the clamping device 10.

Referring to fig. 2, in some embodiments, the clamping device 10 further comprises a vacuum diverter 24, through which vacuum nozzle 23 communicates with the vacuum generator 22.

In general, only one vacuum generator 22 is provided for each suction unit 2, but the number of vacuum nozzles 23 in a set of vacuum nozzles 23 may be plural, and in order to ensure that the negative pressure generated for each vacuum nozzle 23 is the same, a vacuum splitter 24 is separately connected to each vacuum nozzle 23, specifically, the vacuum splitter 24 includes an input end and a plurality of output ends, the input end is connected to the vacuum generator 22, each output end is connected to one vacuum nozzle 23, for example, the number of output ends is five, the number of vacuum nozzles 23 in each set is also five, and one output end is connected to one vacuum nozzle 23.
