[0022] It should be noted that the temperature of the temperature control bin 6 can be controlled to be close to the temperature of the whole battery, so that the battery does not rapidly cool and dissipate heat, that is, the temperature change is small and slow, which is beneficial to lock the temperature abnormal part and further detect.

[0023] In the embodiment, the battery transfer assembly 5 comprises a moving seat 51, a second telescopic rod 55 and a moving wheel 56, wherein the moving seat 51 is movably arranged on the track 4 by the moving wheel 56, and the second telescopic rod 55 is further arranged on the moving seat 51, and the adsorption disc is fixed on the second telescopic rod 55.

[0024] In addition, the first telescopic rod 52 is further fixed on the moving seat 51, the lifting plate 53 is fixed on the first telescopic rod 52, the middle part of the lifting plate 53 is sealingly and slidably connected with the second telescopic rod, and the sealing frame 54 is fixed around the lifting plate 53, so as to realize the sealing of the second opening 8 by the sealing frame and the lifting plate 53.

[0025] That is, the first telescopic rod and the second telescopic rod do not affect each other, the first telescopic rod 55 can realize the lifting of the battery, and the second telescopic rod can realize the lifting of the lifting plate.

[0026] In the embodiment, the lower part of the top seat 3 is rotatably provided with a positioning plate 12, the positioning plate 12 can be rotated to the lower part of the second opening 8, the positioning plate 12 is a transparent plate body, and the surface has grid lines, and the grid points of the grid lines are marked with coordinates.

[0027] One side of the temperature control bin 6 is provided with a visual sensor 10 and a mechanical hand, the visual sensor 10 can shoot the positioning plate and the battery located below the positioning plate, so as to obtain the nut coordinate data on the battery, and according to the nut coordinate data, the mechanical hand moves the plurality of nut screwing assemblies 9 to the specified position so as to simultaneously disassemble the nuts on the battery.

[0028] It should be noted that when the battery transfer assembly 5 moves to the lower part of the second opening 8, the position of the battery transfer assembly 5 does not need to be adjusted and positioned, even if the battery transfer assembly 5 is not located directly below the second opening, the nuts on the battery can still be positioned through the positioning plate, which is more convenient and efficient as a whole, and by configuring the positioning plate, the plurality of nut screwing assemblies 9 can be moved to the specified position so as to simultaneously disassemble the nuts on the battery, and then the battery can be further detected by using a temperature measuring instrument and the like.

[0029] In the embodiment, the nut screwing assembly 9 comprises a suction seat 91, a push rod 93, a mounting seat 94 and a control ring capsule 95. The top of the suction seat 91 is embedded with a magnetic block 92 which can be adsorbed to the top of the temperature control bin 6. The bottom of the suction seat 91 is connected with the mounting seat 94 by an elastic member 96. The outside of the mounting seat 94 is sleeved with the control ring capsule 95. The push rod 93 is vertically slidably arranged in a temporary storage groove of the suction seat 91. The temporary storage groove is connected with the control ring capsule 95 by a pipeline.

[0030] In the implementation, when the robot hand grabs the nut screwing assembly, the robot hand can grab the control ring capsule part. At this time, the control ring capsule is squeezed, and the liquid in the control ring capsule enters the temporary storage groove through the pipeline, thereby driving the push rod 93 upward. When the push rod 93 contacts the top of the temperature control bin 6, the push rod 93 stops moving upward, and the liquid in the temporary storage groove continues to increase, thereby moving the suction seat 91 downward, so that the magnetic block 92 is separated from the top of the temperature control bin. When the robot hand grabs the nut screwing assembly to the specified position, the robot hand gradually releases the control ring capsule. At this time, the liquid in the temporary storage groove gradually returns to the control ring capsule under the action of gravity, and the suction seat 91 can be adsorbed to the top of the temperature control bin 6 under the action of the magnetic block 92, thereby completing the positioning of the nut screwing assembly.

[0031] In the embodiment, the mounting seat 94 is embedded with a screwing motor. The output end of the screwing motor is connected with an inner shaft 97. The bottom of the inner shaft 97 is fixed with a screw head.

[0032] As a preferred embodiment, the elastic member 96 can be vertically elastically stretched and cannot be twisted relatively. For example, the elastic member 96 comprises a square groove and a square block slidably arranged in the square groove. The cooperation between the square groove and the square block enables the square groove and the square block to slide relatively and not to twist relatively. A spring or an elastic pad can be arranged between the square groove and the square block.

[0033] It should be noted that the elastic member 96 actually has two functions. One is to provide a space for the action of the suction seat 91 separating from or adsorbing to the top of the temperature control bin during the movement and positioning of the nut screwing assembly. The other is to provide a space for the action of the screw head rising with the bolt during the screwing of the bolt.

[0034] As a preferred embodiment, the outer part of the inner shaft 97 is rotationally connected with an outer ring 98. The outer ring 98 is rotationally arranged in the mounting seat 94. The top of the outer ring 98 is fixed with an expansion ring. A ratchet mechanism is arranged between the expansion ring and the inner shaft 97. The bottom of the outer ring 98 is fixed with a wrench sleeve.

[0035] That is, in the embodiment, the screw head or the wrench sleeve can be selected according to the actual situation to disassemble the corresponding nut, when the wrench sleeve is selected to be used, the nut screwing assembly can be driven to rotate by the mechanical hand, so that the wrench sleeve is adjusted in the orientation to adapt to the bolt, when the screw head is selected to be used, the screw head can be driven to rotate by the rotation of the screwing motor, so that the screw head is adjusted in the orientation to adapt to the bolt, in the process, since the ratchet mechanism is configured, the wrench sleeve will not rotate, which makes that when the screw head and the wrench sleeve are selected to be used synchronously, after the wrench sleeve is positioned, the screw head is adjusted, the wrench sleeve will not be affected, then the screwing motor is reversely rotated.

[0036] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art, according to the technical solution and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
