[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figures 1 to 8 A non-destructive clamping device for end plates used in the production of battery trays comprises a mounting plate 1, a lifting plate 2, two inverted U-shaped frames 3, and two clamping plates 4. Two mounting frames 5 are fixedly provided on the upper side of the mounting plate 1. A plurality of mounting holes 6 are provided on the upper side of the mounting frames 5. Before use, the mounting plate 1 needs to be fixed on the handling equipment through the mounting frames 5 and the mounting holes 6, and then the battery tray is transported by cooperating with the handling equipment and the clamping device.

[0032] like Figure 2 , Figure 4 , Figure 7As shown, the inverted U-shaped frame 3 is slidably connected to the lower side of the lifting plate 2, and a synchronous displacement driving component is provided between the two inverted U-shaped frames 3. The synchronous displacement driving component is used to drive the two inverted U-shaped frames 3 to move closer to or away from each other. The synchronous displacement driving component includes a translation cylinder 16. A through hole is provided on one side of an inverted U-shaped frame 3. The translation cylinder 16 is fixed on the inner side of the through hole. The translation cylinder 16 is externally connected to the electromagnetic valve through an air pipe. A connecting frame 17 is fixed on the shaft end of the translation cylinder 16. The connecting frame 17 is fixed on one side of the other inverted U-shaped frame 3. The lower side of the lifting plate 2 is provided with a There are two cross long holes 18, two cross sliders 19 are fixed on the upper side of the inverted U-shaped frame 3, the cross slider 19 slides on the inner side of the cross long hole 18, a translation rod 20 is provided above the inverted U-shaped frame 3, the translation rod 20 is fixed on the upper side of the two cross sliders 19, a translation synchronization component is provided between the two translation rods 20, and the translation synchronization component includes a gear 21, and the gear 21 rotates on the upper side of the lifting plate 2 through a rotating shaft, a synchronization rod 22 is fixed on the side where the two translation rods 20 are close to each other, and a rack is fixed on the side where the two synchronization rods 22 are close to each other. 23, the rack 23 is connected with the gear 21 through meshing transmission, and a stabilizing slider 24 is fixedly arranged on the lower side of the synchronization rod 22. The stabilizing slider 24 is a cross-shaped structure, and the stabilizing slider 24 slides on the inner side of the cross long hole 18. When the battery tray needs to be clamped, the battery tray needs to be located between the two clamping plates 4, and then the translation cylinder 16 is controlled to retract. When the translation cylinder 16 retracts, the two inverted U-shaped frames 3 and the clamping plates 4 are driven to approach each other, so that the battery tray can be automatically clamped, and during the clamping period, the cross slider 19 and the translation rod 20 It will move with the inverted U-shaped frame 3, and the translation rod 20 will also drive the synchronization rod 22 and the rack 23 to move together. When the rack 23 moves, it will drive the gear 21 to rotate. Since the two racks 23 are meshed with the gear 21, when the translation cylinder 16 retracts, the two racks 23 move the same distance, so that when the battery tray is clamped, it is in the middle and lower position of the lifting plate 2, with good balance, and after clamping the battery tray, the cross slider 19 cannot move, thereby fixing the position of the battery tray, with high stability.

[0033] like Figure 5 , Figure 6As shown, the clamping plate 4 is fixed on the lower side of the inverted U-shaped frame 3, and two force control clamping components are provided on the side where the clamping plates 4 are close to each other. The force control clamping components are used to prevent the end plate of the battery tray from being damaged during clamping. The force control clamping components include an L-shaped clamping claw 25, and a connecting hole is provided on one side of the clamping plate 4. The L-shaped clamping claw 25 slides on the inner side of the connecting hole. A limit plate 26 is fixedly provided on one side of the L-shaped clamping claw 25, and a plurality of springs 27 are fixedly provided on the other side of the L-shaped clamping claw 25. An anti-skid pad 30 is fixedly provided on the side of the L-shaped clamping claw 25 away from the spring 27, and a plurality of anti-skid grooves are provided on the side of the anti-skid pad 30 away from the L-shaped clamping claw 25.

The pressure sensor 28 is connected to an external power supply and a processor through a wire. The other end of the spring 27 is fixed on one side of the force plate 29. The force plate 29 is located at the pressure sensor 28 and the spring 27, during the clamping of the battery tray, when the translation cylinder 16 retracts, the L-shaped clamp 25 and the anti-skid pad 30 will automatically approach the two side end plates of the battery tray, and when the anti-skid pad 30 contacts the two side end plates of the battery tray, the L-shaped clamp 25 and the anti-skid pad 30 will stop moving. At this time, the translation cylinder 16 continues to retract, and then the spring 27 will be compressed, and the clamping force applied by the anti-skid pad 30 to the end plate of the battery tray will also increase. At this time, the pressure sensor 28 will detect the tension of the spring 27, thereby indirectly knowing the clamping force applied to the end plate of the battery tray. When the pressure detected by the pressure sensor 28 reaches a certain value, the translation cylinder 16 can be controlled to stop retracting, thereby preventing the end plate of the battery tray from being subjected to a large clamping force, thereby preventing the end plate of the battery tray from being clamped and damaged, thereby realizing the controllable clamping force function.

[0034] like Figure 2As shown, the lifting plate 2 is located below the mounting plate 1. In a top-down state, the lifting plate 2 is perpendicular to the mounting plate 1. A lifting connection assembly is provided between the lifting plate 2 and the mounting plate 1. The lifting connection assembly is used to connect the lifting plate 2 and the mounting plate 1. The lifting connection assembly is used to drive the lifting plate 2 to rise or fall. The lifting connection assembly includes a U-shaped guide frame 14. Both ends of the U-shaped guide frame 14 are fixed to the upper side of the lifting plate 2. A through hole and two guide holes are provided on the upper side of the mounting plate 1. A hydraulic cylinder 15 is fixed on the inner side of the through hole. The hydraulic cylinder 15 is externally connected to a solenoid valve through an oil pipe. The shaft end of the hydraulic cylinder 15 is fixed to the U-shaped guide frame 14. To the lower bottom side of the frame 14, the U-shaped guide frame 14 slides inside the guide hole. When the battery tray is clamped, the hydraulic cylinder 15 can be controlled to extend. When the hydraulic cylinder 15 extends, the lifting plate 2, the U-shaped guide frame 14 and the battery tray can be driven to rise together, so that the battery tray can be raised, which is convenient for the subsequent transportation of the battery tray, thereby realizing auxiliary transportation. When the hydraulic cylinder 15 retracts, the lifting plate 2, the U-shaped guide frame 14 and the L-shaped clamp 25 can be lowered, so that before the battery tray is needed, the L-shaped clamp 25 can be lowered close to the battery tray, thereby facilitating the clamping of the battery tray.

[0035] like Figure 3 , Figure 8 As shown, the two ends of the mounting plate 1 are provided with transfer anti-drop components, which are used to prevent the battery tray from falling during the transfer of the battery tray. The transfer anti-drop components include two U-shaped fixing seats 7, and the two U-shaped fixing seats 7 are respectively fixed on the two sides of the mounting plate 1 that are far away from each other. A rotating frame 8 is rotatably provided on the inner side of the U-shaped fixing seat 7, and a protective angle frame 9 is fixedly provided on the bottom side of the rotating frame 8. A receiving groove 10 is provided on the upper end of the rotating frame 8, and a rotating block 11 is rotatably provided on the inner side of the receiving groove 10. An opening and closing cylinder 12 is fixedly provided between the two rotating blocks 11, and the opening and closing cylinder 12 is externally connected to an electromagnetic valve through an air pipe. A baffle 13 is fixedly provided on one side of the U-shaped fixing seat 7, and the baffle 13 can contact the rotating frame 8. During the transportation of the battery tray, the battery tray needs to be clamped first, and then the control The control hydraulic cylinder 15 is extended to raise the battery tray, and then the opening and closing cylinder 12 can be controlled to extend. When the opening and closing cylinder 12 is extended, the two rotating frames 8 can be rotated, so that the two protective angle frames 9 can automatically approach the battery tray. When the opening and closing cylinder 12 is fully extended, the protective angle frames 9 will be located at the lower position of the corner of the battery tray. Then the battery tray can be moved and transported, which can prevent the battery tray from falling during the movement and transportation. Even if the anti-slip pad 30 does not clamp the battery tray, the battery tray will not fall, which has higher safety. When the opening and closing cylinder 12 is fully extended, the rotating frame 8 will also contact the baffle 13, so that the two rotating frames 8 cannot rotate, and the protective angle frames 9 can be positioned, which has higher stability.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
