The following description will be made with reference to the accompanying drawings, in which the pick-and-place mechanism 20 is combined with the tray 10, and the process of compressing the battery cell 200 after the combination is performed: firstly, the transfer robot 60 drives the pick-and-place mechanism 20 to slide to a position right below the tray 10 supported by the supporting platform 30, and the butting gas pipe body 23 of the pick-and-place mechanism 20 is aligned with the main gas pipe joint 14 of the tray 10 up and down; then, the transfer robot 60 drives the pick-and-place mechanism 20 to slide upwards, so that the mechanism frame 21 of the pick-and-place mechanism 20 upwards lifts the tray 10; then, the horizontal driver 221 operates to drive the horizontal sliding base 224 to slide together with the first upper and lower drivers 222, the second upper and lower drivers 223 and the pulling block 225 thereon until the pulling block 225 on the first upper and lower drivers 222 slides to be right above the pulling block 123 in the first pressing assembly 12 and the pulling block 225 on the second upper and lower drivers 223 slides to be right above the pulling block 133 in the second pressing assembly 13; finally, the first up-down driver 222 pulls the pushed block 123 to slide downwards through the pulling block 225 thereon, and simultaneously, the second up-down driver 223 pulls the pushed block 133 to slide downwards through the pulling block 225 thereon, so as to finally realize the purpose that the upper pressing block 122 of the first pressing assembly 12 and the upper pressing block 132 of the second pressing assembly 13 press the battery cell 200 downwards together; in the process that the first compressing assembly 12 compresses the battery cell 200, the main air pipe joint 14 slides downwards along with the first compressing assembly 12, the main air pipe joint 14 sliding downwards is in butt joint with the butt joint air pipe body 23, and an air source is introduced into the main air pipe joint 14 by the butt joint air pipe body 23.

Compared with the prior art, by means of the transfer manipulator 60, the pick-and-place mechanism 20 installed on the transfer manipulator 60, and the supporting platform 30, the water removal device 50 and the cleaning machine 40 located beside the transfer manipulator 60, the pick-and-place mechanism 20 is driven by the transfer manipulator 60 to sequentially transfer the tray 10 supported by the supporting platform 30 and the battery cells 200 on the tray 10 to the cleaning machine 40 and the water removal device 50, and then rotate to the supporting platform 30, so that the cleaning efficiency of the battery cells 200 is improved. Meanwhile, the pulling device 22 of the pick-and-place mechanism 20 keeps a state of driving the first compressing assembly 12 and the second compressing assembly 13 to compress the battery cell 200 together in the process that the battery cell 200 on the tray 10 is cleaned by the cleaning machine 40, the butt gas pipe 23 also conveys gas into the main gas pipe joint 14, so that the gas entering the main gas pipe joint 14 flows into the gas cavity 151, and then the gas flowing into the gas cavity 151 seals the end part 220 (see fig. 8) of the battery cell 200, which extends into the gas cavity 151 and is located by the pole 210, because the gas flowing into the gas cavity 151 causes the gas pressure in the gas cavity 151 to be greater than the external gas pressure, the cleaning liquid sprayed by the cleaning machine 40 is effectively prevented from entering the gas cavity 151, and the sprayed cleaning liquid is effectively prevented from entering the battery cell 200; furthermore, since the butt-joint gas pipe body 23 is in butt-joint communication with the main gas pipe joint 14 during the process that the pulling device 22 drives the first pressing assembly 12 to press the battery cell 200 downwards, the gas source is introduced into the tray 10 through the pick-and-place mechanism 20, and the reliability of water resistance of the tray 10 when being combined with the pick-and-place mechanism 20 is ensured.

It should be noted that the tray 10 is only combined with the pick-and-place mechanism 20 at the cleaning machine 40, and the tray 10 is separated from the pick-and-place mechanism 20 at the water removing device 50 and the supporting platform 30, that is, the pick-and-place mechanism 20 separates the tray 10 from the tray 10 after placing the tray 10 at the water removing device 50 or the supporting platform 30.

The above disclosure is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, so that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
