[0028] like Figure 1 and Figure 2 As shown, the mobile mechanism 1 includes a flat plate 101, a controller 102 is installed on the front surface of the flat plate 101, four suspension brackets 103 are fixed on the top of the flat plate 101, a T-shaped slot 104 is provided at the bottom of the flat plate 101, and a T-shaped block 105 is slidably connected inside the T-shaped slot 104, which can provide an installation position for the servo electric cylinder 106 under the action of the T-shaped block 105.

[0029] like Figure 1 and Figure 2 As shown, a servo electric cylinder 106 is installed at the bottom of the T-shaped block 105, a threaded rod 107 is movably passed through one side of the flat plate 101, and a motor 108 is installed on one side of the flat plate 101, so that the threaded rod 107 can be driven to rotate under the cooperation of the started motor 108, the T-shaped slot 104 and the flat plate 101.

Under the action of the controller 102, it can be decided whether to start the motor 108.

[0033] The method of use and working principle of this device: When it is necessary to carry out unloading operation on the battery cell string that has completed the welding operation, first use the four hanging brackets 103 and the prepared bolts to hang the flat plate 101 at the appropriate position of the string welding machine, then connect the controller 102 (PLC controller) to the external power supply, and then use the controller 102 to start the servo electric cylinder 106. The started servo electric cylinder 106 will drive the entire clamping mechanism 2 to move vertically downward. When the two sliders 203 are moved to the appropriate position (the upper sides of the two sliders 203 are on the same horizontal plane as the bottom of the battery cell string that has completed the welding operation), the controller 102 is used to first turn off the servo electric cylinder 106, and then start the two electric push rods 202. The servo electric cylinder 106 that is closed at this time will stop the entire clamping mechanism 2 from moving vertically downward. At the same time, the two activated electric push rods 202 will drive the corresponding slider 203 to move inside the guide rail 201 (the two sliders 203 move toward each other). When the surfaces of the two sliders 203 are respectively in contact with the two sides of the battery cell string that has completed the welding operation, the upper sides of the two sliders 203 are in contact with the bottom of the battery cell string that has completed the welding operation. At the same time, the controller 102 is used to close the two electric push rods 202. At this time, the two closed electric push rods 202 will stop the corresponding slider 203 from moving. Then, the controller 102 is used to start the two micro air pumps 205 and two of the electric valves 209. At this time, the two activated micro The air pumps 205 will, with the cooperation of the corresponding electric valves 209, extract the air in the environment and transport it to the inside of the corresponding shell 206. At the same time, the two rectangular blocks 207 will move vertically downward with the cooperation of the corresponding shell 206 and the air entering the corresponding shell 206. The two rectangular blocks 207 that move vertically downward will, with the cooperation of the corresponding shell 206, cause the corresponding springs 208 to undergo elastic deformation. At the same time, the two rectangular blocks 207 that move vertically downward will drive the corresponding anti-slip pads 210 to move vertically downward. When the two anti-slip pads 210 are moved to the point where they can no longer move, the controller 102 is used to close the two micro air pumps 205 and two of the electric valves 209. At this time, the two anti-slip pads 210 will stop moving vertically downward with the cooperation of the two closed micro air pumps 205, two closed electric valves 209, two shells 206 and two rectangular blocks 207. At the same time, the two anti-slip pads 210 that have stopped moving vertically downward will clamp and fix the battery cell string that has completed the welding operation with the cooperation of the corresponding sliders 203. Then, the servo electric cylinder 106 is started by the controller 102. At this time, the started servo electric cylinder 106 will drive the clamped battery cell string to move vertically upward with the cooperation of the clamping mechanism 2. When the guide rail 201 is reset to its original position, the servo electric cylinder 106 is directly turned off by the controller 102 first, and then the motor 108 is started. At this time, the closed servo electric cylinder 106 will stop the battery cell string from moving vertically upward.The motor 108 started at the same time will drive the threaded rod 107 to rotate inside the T-slot 104 with the cooperation of the flat plate 101, and the rotating threaded rod 107 will drive the servo electric cylinder 106 to move horizontally with the cooperation of the T-slot 104 and the T-block 105. At the same time, the horizontally moving servo electric cylinder 106 will drive the battery string to move horizontally with the cooperation of the clamping mechanism 2. When the battery string moves to the appropriate position, the controller 102 is directly used to first turn off the motor 108, and then start the servo electric cylinder 106. At this time, the turned-off motor 108 will, with the cooperation of the above-mentioned components, The servo electric cylinder 106 stops moving horizontally, and the activated servo electric cylinder 106 causes the clamped battery cell string to move vertically downward until the bottom of the battery cell string contacts the inner wall of the prepared battery cell string collection box. Then, the controller 102 is used to activate the other two electric valves 209. At this time, the other two activated electric valves 209 will release the air inside the corresponding shell 206. At the same time, the two corresponding rectangular blocks 207 will reset under the cooperation of the corresponding shell 206 and the corresponding spring 208. The two rectangular blocks 207 that are reset are 07 will drive the corresponding anti-skid pad 210 to reset and move. When the two anti-skid pads 210 are reset to their original positions, the two anti-skid pads 210 are separated from the battery cell string. Then, the controller 102 is directly used to close the other two electric valves 209 first, and then the two electric push rods 202 are started. At this time, the two started electric push rods 202 will drive the corresponding slider 203 to reset and move. When the two sliders 203 are reset to their original positions, the two sliders 203 are separated from the battery cell string. At the same time, the controller 102 is used to close the two electric push rods 202 first, and then the servo electric cylinder 10 is started. 6. The servo electric cylinder 106 started at this time will drive the entire clamping mechanism 2 to move vertically upward. When the clamping mechanism 2 moves to the point where it can no longer move, the controller 102 is directly used to first turn off the servo electric cylinder 106, and then the motor 108 is started. At this time, the started motor 108 will, with the cooperation of the above-mentioned components, drive the servo electric cylinder 106 and the entire clamping mechanism 2 to move horizontally. When the servo electric cylinder 106 and the entire clamping mechanism 2 are reset to their initial positions, the motor 108 is directly turned off, and then the above-mentioned operation steps are followed to perform the unloading operation on the remaining battery cell strings that have completed the welding operation. The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms. Any technician familiar with this profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
