Description

Technical Field

[0001] This utility model belongs to the field of lithium battery production technology, and in particular relates to a lithium battery cell gripping robot with flexible clamping material. Background Technology

[0002] Lithium-ion battery cells are the most basic component of batteries. They are usually encapsulated in a metal casing and convert chemical energy into electrical energy through a chemical reaction. Currently, in the production process of square lithium-ion battery packs, robotic arms are needed to transfer the cells to the encapsulation shell for packaging.

[0003] Most existing lithium battery cell gripping robots use L-shaped plastic grippers. The surface of the L-shaped grippers is coated with polytetrafluoroethylene (PTFE) to improve their wear resistance. The L-shaped grippers use a lifting and pressing mechanism to grip and fix the lithium battery cells, thereby achieving the transfer of lithium battery cells. However, during use, the contact area between the L-shaped grippers and the lithium battery cells is relatively small, resulting in a concentrated stress point on the lithium battery cells during gripping. Since the lithium battery cell material is fragile, it is easily damaged when gripped. Furthermore, the PTFE coating will wear down after prolonged use, causing the L-shaped grippers to scratch the lithium battery cells, which is detrimental to their use.

[0004] To address these issues, we provide a lithium battery cell gripper with a flexible clamping material. Utility Model Content

[0005] The purpose of this invention is to provide a lithium battery cell gripping robot with flexible clamping material. By combining the flexible clamping component and the clamping force dispersing component, it solves the problem that the force points of the battery cell are relatively concentrated when the battery cell is clamped and fixed in the prior art, which easily leads to the damage of the battery cell.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a lithium battery cell gripping robot with a flexible clamping material, comprising an electric cylinder, a flexible clamping assembly, and a clamping force dispersing assembly. A servo motor is fixedly connected to the bottom of the output end of the electric cylinder, and a U-shaped gripper is fixedly connected to the top of the output end of the servo motor. The flexible clamping assembly includes a wear-resistant sponge pad, the bottom of which is fixedly connected to the inner wall of the U-shaped gripper. A limit frame is fixedly connected to the top of the inner cavity of the U-shaped gripper, and an elastic airbag is fixedly connected to the top of the inner cavity of the limit frame. An air chamber is fixedly connected to the top of the U-shaped gripper, and the right side of the air chamber is connected to the elastic airbag via a conduit. Pistons are provided on the front and rear sides of the inner cavity of the air chamber, and push rods are fixedly connected to opposite sides of the two pistons. A control mechanism is fixedly connected to the left side of the top of the U-shaped gripper, and the front and rear sides of the control mechanism are fixedly connected to the push rods. The clamping force dispersing assembly includes a cylinder, and the right side of the cylinder is fixedly connected to the U-shaped gripper. A connecting plate is fixedly connected to the left side of the cylinder output end, and a top rod is fixedly connected to the bottom right side of the connecting plate. A ramp is provided on the right side of the top rod, and a support plate is fixedly connected to the top of the ramp. The left side of the support plate is movably connected to the inner wall of the U-shaped gripper. An electric cylinder is used to control the working height of the U-shaped gripper, and a servo motor controls the working orientation of the U-shaped gripper to facilitate the transfer of the battery cell to a designated position. A wear-resistant sponge pad protects the battery cell from damage during the clamping process of the U-shaped gripper. A limit frame controls the movement direction of the elastic airbag, causing it to clamp and fix the battery cell downwards. An air chamber and piston push air into the elastic airbag, causing it to expand and complete the clamping work. The cylinder and connecting plate are used to adjust the working position of the top rod. The ramp and top rod work together to adjust the working angle of the support plate. The support plate lifts the bottom of the battery cell, increasing the contact area between the U-shaped gripper and the battery cell, thus dispersing the clamping force and preventing the clamping force from concentrating in one place on the battery cell.

[0008] The present invention is further configured such that the control mechanism includes a housing, the bottom of which is fixedly connected to a U-shaped gripper, a rotary motor is fixedly connected to the bottom of the inner cavity of the housing, and screws are fixedly connected to the front and rear sides of the output end of the rotary motor. A telescopic rod is threaded onto the surface of the screw, and the opposite sides of the two telescopic rods penetrate the housing and are fixedly connected to a push rod. The rotary motor, screws, and telescopic rods are used to adjust the positions of the two push rods and the piston.

[0009] The present invention is further configured such that guide strips are fixedly connected to the front and rear sides of the bottom of the inner cavity of the equipment shell, guide blocks are slidably connected to the surface of the guide strips, and the top of the guide blocks are fixedly connected to the telescopic rod. Through holes for use with the telescopic rod are provided on the front and rear sides of the equipment shell. The guide strips and guide blocks facilitate the limiting of the telescopic rod, enabling it to move smoothly and preventing it from rotating with the screw.

[0010] The present invention is further configured such that a sliding rod is fixedly connected to the front and rear sides of the bottom of the U-shaped gripper, and a sliding sleeve is slidably connected to the surface of the sliding rod. The opposite sides of the two sliding sleeves are fixedly connected to the connecting plate. After the sliding sleeves are fixed to the connecting plate, they cooperate with the sliding rod to improve the stability of the connecting plate during movement.

[0011] The present invention is further configured such that the left side of the tray is movably connected to the inner wall of the U-shaped gripper via a rotating shaft, and the top of the tray is fixedly connected to the wear-resistant sponge pad.

[0012] The present invention is further configured such that the wear-resistant sponge pad and the elastic airbag are both made of flexible materials, and a limit baffle is fixedly connected to the right side of the bottom of the tray.

[0013] The present invention is further configured such that a stabilizing plate is fixedly connected to the bottom of the output end of the servo motor, and the right side of the stabilizing plate is fixedly connected to a U-shaped gripper.

[0014] The present invention is further configured such that the servo motor and the U-shaped gripper are fixedly connected by a connecting frame, and a reinforcing plate is fixedly connected to the top of the connecting frame. The right side of the reinforcing plate is fixedly connected to the U-shaped gripper. The reinforcing plate is used to improve the stability of the connecting frame and the U-shaped gripper after installation and fixation, and to prevent the connection from becoming loose.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model uses a flexible clamping assembly and a control mechanism to adjust the position of the two pistons, so that the pistons deliver air from the air chamber to the elastic airbag. After the elastic airbag expands, it cooperates with the wear-resistant sponge pad to clamp and fix the battery cell located in the U-shaped claw. Because the battery cell is clamped and fixed with flexible materials, damage to the battery cell is prevented. Moreover, the elastic airbag and the wear-resistant sponge pad fix the battery cell through elastic clamping, which improves the service life of the U-shaped claw.

[0017] 2. This utility model uses a clamping force dispersion component. After the U-shaped gripper places the battery cell inside, the cylinder and connecting plate control the top rod to squeeze the inclined surface of the inclined block, so that the inclined block pushes the support plate to a horizontal state. The support plate lifts the bottom of the battery cell, increasing the contact area between the U-shaped gripper and the battery cell. During the clamping process, the clamping force is evenly distributed to the surface of the battery cell, preventing the clamping force from concentrating in one place on the battery cell, which could cause damage.

The cylinder 51 is then activated, and the cylinder 51, in conjunction with the connecting plate 52, controls the push rod 53 to press the inclined block 54. After the inclined block 54 is pressed, the control plate 55 is kept horizontal, increasing the contact area between the U-shaped gripper 3 and the battery cell. During the clamping process, the clamping force is evenly distributed to the surface of the battery cell, preventing the clamping force from concentrating in one place and causing damage. Finally, the rotary motor 482 is activated, rotating... The motor 482 and the screw 483 work together to control the movement of the telescopic rod 484 and the push rod 47. The movement of the push rod 47 drives the two pistons 46 to move to opposite sides. After the two pistons 46 move, the air inside the air chamber 44 is transported to the elastic airbag 43 through the conduit 45. After the elastic airbag 43 is inflated, it extends downward through the limit frame 42. The elastic airbag 43 and the U-shaped gripper 3 clamp and fix the battery cell. Because the battery cell is clamped and fixed with flexible materials, damage to the battery cell is prevented.
