Moreover, the description should not be construed as limiting the scope of the embodiments described herein.

[0023] According to one embodiment of the utility model, a battery cell transport clamp is provided, comprising: a fixed plate 11, the fixed plate 11 is used to connect a three-axis module or a connecting robot, two side plates 12 are symmetrically installed below the fixed plate 11, each side plate 12 is respectively provided with an upper supporting part 13 and a lower pressing part 14 for clamping the battery cell, the two upper supporting parts 13 are used to contact the bottom of the battery cell, and the two lower pressing parts 14 are used to contact the upper surface of the battery cell opposite to the bottom, and also includes a blowing assembly for blowing up the pole ears on both sides of the battery cell, so that when the transport clamp clamps the battery cell and transports it, the blowing assembly is used to keep the pole ears roughly in a horizontal state without sagging.

[0024] It can be understood that the upper supporting portion 13 and the lower pressing portion 14 form a structure for clamping the battery cell, which is used to act simultaneously and clamp the battery cell in the upper and lower directions.

[0025] In one embodiment, the blowing assembly includes a blowing portion 21 disposed on the bottom side of the upper supporting portion 13, and an air pipe 22, wherein a first end of the air pipe 22 is connected to the blowing portion 21, and a second end of the air pipe 22 is used to connect to an air source.

[0026] In the above embodiment, the second end of the air pipe 22 is fixedly connected to the mounting seat 31, and a speed regulating valve 32 is provided on the mounting seat 31. The mounting seat 31 has an air duct for connecting the second end of the air pipe 22 with the air outlet end of the speed regulating valve 32, and the air inlet end of the speed regulating valve 32 is used to connect to the air source.

[0027] The purpose of setting the mounting seat 31 is to facilitate the connection of the speed regulating valve 32. The regulating valve 32 mentioned in the utility model is a purchased part, which can be a speed regulating valve purchased from Ningbo AirTac Automation Industry Co., Ltd., model PTL4M5B-M.

[0028] The blowing part 21 mentioned in the above text can be a flat air nozzle. The wind blown by the flat air nozzle can effectively blow up the tabs on both sides of the battery cell and make them roughly horizontal, so as to prevent the tabs from sagging due to gravity, thereby preventing the tabs from being pressed to the bottom of the battery cell and causing damage.

[0029] In some embodiments, two sliding frames 61 are also included, and two pressing parts 14 are respectively arranged on the sliding frames 61. The telescopic ends of the pressing parts 14 can move up and down relative to the sliding frames 61. Each sliding frame 61 is slidably connected to each side plate 12, and also includes a compression spring for causing the sliding frame 61 to have an upward movement tendency relative to the side plate 12, and a photoelectric switch 62 for sensing the relative movement of the sliding frame 61 relative to the side plate 12.

[0030] Adding the sliding frame 61 on the side plate 12 is beneficial to the upper supporting part 13 of the clamping claw to collide with the machine in an accident, for example, when the steel collide, the sliding frame 61 moves upward relative to the side plate 12 to protect the clamping claw. The photoelectric switch 62 can be set to stop the machine in time in an accident.

[0031] The sliding frame 61 can slide up and down relative to the side plate 12 by the following structure, for example, a vertical slide groove can be provided on the side plate 12, and a slider can be provided on the sliding frame 61, and the slider is used to move along the slide groove. Specifically, the cross section of the slide groove can be T-shaped, and the sliding frame 61 can also be prevented from falling off from the side plate 12.

[0032] In order to arrange the compression spring, a first groove for accommodating the compression spring may be provided on the sliding frame 61, and a second groove for accommodating the compression spring may be provided on the side plate 12, with the two ends of the compression spring respectively fixed to the top of the first groove of the sliding frame 61 and the bottom of the second groove of the side plate 12. Thus, the compression spring acts to make the sliding frame 61 move upward relative to the side plate 12.

[0033] In one embodiment, the photoelectric switch 62 is fixedly mounted on the side panel 12, and a baffle 81 is fixedly mounted on the sliding frame 61. The side panel 12 is also provided with a limit block for limiting the downward movement of the sliding frame 61, so that when the sliding frame 61 abuts against the limit block, the baffle 81 is used to block the light beam generated by the photoelectric switch 62.

[0034] In some embodiments, the lower pressing part 14 can be a cylinder, the fixed end of the cylinder is fixedly connected to the sliding frame 61, and the telescopic end of the cylinder is connected to the pressure block 91. When the upper supporting part 13 lifts the battery cell, the pressure block 91 connected to the telescopic end of the lower pressing part 14 approaches and presses the battery cell to stably clamp the battery cell during transportation.

[0035] In order to protect the single battery cells during transportation, the outer layer of the upper supporting portion 13 is covered with a rubber sleeve, and the outer layer of the pressing block 91 is also covered with a rubber sleeve.

[0036] In some other embodiments, a sensor for detecting whether there is a battery cell on the upper supporting portion 13 is disposed near the upper portion between the two side plates 12. The sensor here may be a diffuse reflection sensor.
