The sensing end of the proximity switch 1 is vertically downward and corresponds to the front and rear raised parts 101 of the top surface of the induction frame fixed to the top surface of the right end of the battery storage box 100 conveyed on the transmission roller 11.

[0019] Fixed plates 15 are fixed to the top surfaces of the front and rear side panels of the conveyor frame body 10 on the left side of the two vertical plates 14 , and a correction device is installed on the fixed plate 15 to correct the battery storage box 100 conveyed on the transmission roller 11 .

[0023] Furthermore, a permanent magnet block 271 is nested and fixed in the groove of the left side wall of the shifting and pressing block 27 , and the protruding pushing block 102 is an iron block, and the permanent magnet block 271 corresponds to the protruding pushing block 102 .

[0024] Specifically, multiple positioning proximity switches 2 are fixed from right to left on the outer wall panels of the two movable support frames 20. An external sensing protrusion 231 is fixed in the middle of the outer wall surface of the movable block 23, corresponding to the positioning proximity switches 2. The positioning proximity switches 2 correspond to the corresponding battery cells 200 inserted into the battery storage box 100. The position of the rightmost positioning proximity switch 2 is the initial position of the movable block 23. The distance between each adjacent positioning proximity switch 2 is the distance between two adjacent battery cells 200 in the battery storage box 100.

[0025] Specifically, a lower fixed plate 180 extending forward and backward is fixed to the lower portion of the conveyor frame body 10 to the right of the two vertical plates 14. A lifting cylinder 181 is fixed to the bottom surface of the lower fixed plate 180. The top of the push rod of the lifting cylinder 181 extends out of the top surface of the lower fixed plate 180 and is fixed to a lifting plate 182. A vertical baffle 183 extending forward and backward is fixed to the top surface of the lifting plate 182. The vertical baffle 183 is inserted into a slot extending forward and backward formed in the bottom plate of the conveyor frame body 10. The top of the vertical baffle 183 extends out of the top of the slot and is located between the two corresponding transmission rollers 11. A plurality of vertical guide rods 184 are fixed to the right bottom surface of the lifting plate 182. The vertical guide rods 184 are inserted into corresponding vertical guide holes formed in the lower fixed plate 180.

[0026] All electrical components in this embodiment are electrically connected to the control host through electrical connecting lines, and their operation is controlled by the control host. At the same time, all cylinders are connected to the corresponding solenoid valves of the hydraulic system through connecting pipes, and the solenoid valves are operated to control the flow of oil, thereby controlling the movement of the corresponding cylinders. This is a conventional structure and will not be described in detail here.

[0027] When this embodiment is in use, the battery storage box 100 with the battery cells 200 installed is first placed on the corresponding transmission roller 11 at the right part of the conveyor frame body 10, and the conveying motor 13 is operated to rotate all the transmission rollers 11, so that the battery storage box 100 is conveyed to the left. Then, after the battery storage box 100 is conveyed to the left by at least 50 cm, the second battery storage box 100 can be placed on the corresponding transmission roller 11 at the right part of the conveyor frame body 10 to maintain the distance between the two adjacent battery storage boxes 100 (the front and rear side walls of the battery storage box 100 are close to the two side plates, so that it is offset forward or backward). When the distance is relatively small, it can be ensured that when the subsequent battery storage box 100 is transported to its place, the protrusion 101 is sensed by the corresponding sensing end of the proximity switch 1, and the problem of non-sensing will not occur). When the protrusions 101 at the front and rear of the top surface of the sensing rack on the right side of the first battery storage box 100 are sensed by the corresponding sensing end of the proximity switch 1, it means that it has moved to its place. At this time, the conveying motor 13 stops running. At the same time, the push rod of the lifting cylinder 181 pushes the top of the vertical baffle 183 to extend out of the top surface between the corresponding two transmission rollers 11, which can block the battery storage box 100 that continues to be transported on the right side.

[0028] At this time, the push rod of the oil cylinder 25 pushes, so that the front end of the toggle pressing block 27 extends out of the front wall of the right part of the elongated adjustment slot 18 and is on the right side of the protruding pushing block 102. Then, the moving motor 22 is operated to make the toggle pressing block 27 move to the left until the permanent magnet block 271 is pressed against and adsorbed on the protruding pushing block 102, and continues to move to the left, thereby driving the battery storage box 100 to move to the left until the external sensing protrusion 231 is positioned by the corresponding positioning proximity switch 2 It is sensed (the second one from the right to the left), which means that the battery cell storage box 100 is moved into place. Then, the battery cell storage box 100 is pushed by the push rods of the two clamping cylinders 16 to clamp the battery cell storage box 100 between the two correction clamping plates 17 (its clamping force is greater than the magnetic adsorption force, so that it can perform correction clamping on the battery cell storage box 100) to achieve correction and ensure centering. At this time, the battery cell 200 at the far left is also in the grasping position and can be grasped by the robot arm. It is easy to grasp and the grasping position is accurate.

[0029] After completing one grab, the manipulator resets, the push rods of the two pressing cylinders 16 retract, and the moving motor 22 runs, so that the two toggle pressing blocks 27 move to the left, driving the battery storage box 100 to move to the left, until the third positioning proximity switch 2 from the right to the left is sensed. At this time, it means that the second battery 200 has reached the grabbing position. At this time, the moving motor 22 stops running. As before, the push rods of the two pressing cylinders 16 push the battery storage box 100 to be recalibrated, and then the manipulator grabs it. The degree of automation is high and the effect is good.

[0030] After all the battery cells 200 in the first battery cell storage box 100 have been grabbed, they are removed from the conveyor rack body 10 (the material can be taken out by a robot or manually), the push rod of the lifting cylinder 181 is retracted, and then the conveying motor 13 is operated to continue to convey them to the left. The conveying effect is good and the moving position is accurate, which ensures the accurate grabbing of the robot and ensures that they can be placed normally in the subsequent processing position. It is not easy to deviate and ensures continuous processing.

[0031] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and is susceptible to numerous variations. Any simple modifications, equivalent variations, and modifications to the above embodiments based on the technical essence of the present invention shall be deemed to fall within the scope of protection of the present invention.
