[0002] With the booming development of new energy vehicles, the market demand for new energy battery cells is increasing, and the types of new energy battery cells are also increasing. Nowadays, in the production process of new energy battery cells, stacked battery cell trays have become an important way to transfer battery cells.

[0003] Currently, when using robotic arms to transfer pallets, gripping devices are often added to the execution end of the robotic arm to perform the gripping operation on the pallet. However, when the gripping device grips the pallet, it is often difficult to ensure the stability of the pallet. The lack of fixation in the direction perpendicular to the clamping force makes it easy for the pallet to slip, causing damage to the pallet. Utility Model Content

[0004] To address the problem that existing gripping devices often fail to ensure the stability of pallets when gripping them, and lack fixation in the direction perpendicular to the clamping force, leading to pallet slippage and damage, this application provides a gripping device for battery cell pallets.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution:

[0020] A gripping device for a battery cell tray includes a support base 1, a U-shaped frame 2 mounted on the upper surface of the support base 1, an adsorption box 3 mounted inside the U-shaped frame 2, a driving cavity 4 opened in the middle of the lower part of the support base 1, two communicating grooves symmetrically opened on the lower end surface of the driving cavity 4, a movable frame 5 slidably mounted on the outer side of each of the two grooves, a driving component for driving the two movable frames 5 to move is installed in the driving cavity, a fixing plate 6 is symmetrically mounted on the bottom of each of the two movable frames 5, a gripping plate 7 is mounted on one side of each fixing plate 6, a groove is opened on the upper surface of the gripping plate 7, a clamping component is installed in the groove, and two sets of adsorption mechanisms connected to the adsorption box 3 are symmetrically mounted on the lower end surface of the support base 1.

[0021] The top of the U-shaped frame 2 is fixedly connected to a mounting plate 8, which has multiple fixing holes.

[0022] The driving component includes a bidirectional screw 10 rotatably installed in the driving cavity 4, guide rods 9 symmetrically arranged on both sides of the bidirectional screw 10, and movable blocks 12 respectively helically connected to both ends of the bidirectional screw 10. A motor 11 for driving the bidirectional screw 10 to rotate is installed on the outside of the support base 1. The bidirectional screw 10 is fixedly connected to the output end of the motor 11. Movable blocks 13 are slidably connected in two slide grooves. The top end of the movable block 13 is fixedly connected to the movable block 12, and the bottom end is fixedly connected to the movable frame 5.

[0023] When gripping the battery cell tray, the start motor 11 is activated, driving the bidirectional screw 10 to rotate. Under the limiting cooperation of the two guide rods 9, the moving blocks 13 at both ends move towards each other, thereby driving the movable block 12, the moving frame 5, and the fixed plate 6 to move synchronously. This causes the two sets of gripping plates 7 to move towards each other and engage with the slots on the outside of the battery cell tray. At the same time, the adsorption mechanism can firmly adsorb the upper surface of the battery cell tray around its perimeter, achieving vertical fixation. This improves the stability during gripping, prevents the battery cell tray from slipping, and enhances the safety of operation.

[0024] It should be noted that in actual installation, the outer side of the bidirectional screw 10 is fitted with a corrugated rubber protective cover. The two ends of the protective cover are respectively sealed to the inner wall of the drive cavity 4 and the movable block 12. As the movable block 12 moves and extends, it completely covers the meshing part between the movable block 12 and the bidirectional screw 10, thus playing a role in sealing and dust prevention.

[0025] The clamping component includes a movable plate 14 with one end hinged to the inner wall of the groove and a spring 15 installed below the movable plate 14. The other end of the spring 15 is fixedly connected to the bottom wall of the groove.

[0026] By setting the movable plate 14, during gripping, the gripping plate 7 moves along the slot on the outside of the cell tray, squeezing the movable plate 14 into the groove and compressing the spring 15. When the fixed plate 6 contacts the outer wall of the cell tray, the elastic potential energy generated by the compression of the spring 15 pushes the movable plate 14 outward, so that the two rotating plates 14 have a certain limiting effect on the cell tray, improving the firmness during gripping.

[0027] The adsorption mechanism includes two sets of suction cups 16 symmetrically installed on the lower end face of the support base 1. Two sets of adsorption tubes 17 are symmetrically connected to the outside of the adsorption box 3, and the top end is connected to an air extraction tube 18 that extends through to the outside of the U-shaped frame 2. The two ends of the two sets of adsorption tubes 17 respectively extend through to the bottom end of the support base 1 and are connected to the two sets of suction cups 16.

[0028] During operation, the vacuum pump system is connected to the suction pipe 18. The suction pump system evacuates the adsorption box 3 through the suction pipe 18. The inner cavity of the suction cup 16 is then subjected to a negative pressure state by the suction action of the adsorption pipe 17, which enables the battery cell tray to be firmly adsorbed around the upper surface, thus achieving vertical fixation.
