Description

Technical Field

[0001] The present application relates to the technical field of industrial production devices, and specifically discloses a material grabbing device for producing cylindrical battery modules. Background Art

[0002] Energy storage batteries are widely used in many fields such as 3C digital products and new energy vehicles. In the battery industry, in order to meet the market's requirements for different battery powers and currents, different numbers of batteries need to be assembled to form battery modules so that the power and current output by the battery modules meet the requirements of different products.

[0003] Now for cylindrical battery packs used in semi-automatic production lines, in the prior art, not only a battery module needs to be placed in the cylindrical battery pack, but also a compression spring and a spring pressure plate. The compression springs are placed on the two end surfaces of the battery module and fixed by the spring pressure plate.

[0004] In the prior art, the placement of spring pressure plates and compression springs is usually carried out in a workstation, and a conveying device automatically loads the battery module to be assembled to place the battery module at the assembly station, and a robotic arm and a horizontal clamping device move and place the compression spring and spring pressure plate to automatically clamp and assemble the compression spring and spring pressure plate, so that spring pressure plates and compression springs are installed at both ends of the battery module.

[0005] In the actual installation process, only the spring pressure plate and compression spring on one side of the battery module can be installed in one process, and flipping is required during the different assembly processes on the two sides. In the prior art, after one side is assembled, the spring pressure plate is usually transported to the turntable in advance when assembling the other side. The workpiece to be flipped is placed on the turntable and flipped manually or upside down. After flipping, it is clamped again and the subsequent process steps are completed, which prolongs the assembly time of the battery module.

[0006] Therefore, in view of this, the inventor provides a material gripping device for cylindrical battery module production to solve the above-mentioned problems. Utility Model Content

[0007] The utility model aims to solve the problem that in a traditional battery module assembly station, workpieces that need to be turned over for clamping need to be uniformly turned over on a transfer table, which prolongs the battery module assembly time.

[0008] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a grasping device for the production of cylindrical battery modules, including a robot gripper assembly, a horizontal servo transfer assembly and a servo grasping and discharging assembly arranged on the assembly line along the material conveying direction, and a grasping, lifting and flipping assembly is also provided on one side of the assembly line between the robot gripper assembly and the horizontal servo transfer assembly, and the grasping, lifting and flipping assembly includes a flip stand, a flip clamping structure vertically sliding on the flip stand, and a vertical driving structure arranged on the flip stand for driving the flip clamping structure to slide vertically. The flip clamping structure includes a flip clamping frame driven to rise and fall by the vertical driving structure, a pneumatic clamping mechanism rotatably connected to the inner side of the flip clamping frame, and a rotating driving mechanism arranged on one side of the flip clamping frame and used to drive the pneumatic clamping mechanism to rotate.

[0009] Furthermore, the pneumatic clamping mechanism includes an active clamping plate rotatably connected to one side of the flip clamping frame, an adapter plate sliding on one side of the flip clamping frame, a driven clamping plate rotatably connected to the inner side of the adapter plate and capable of rotating synchronously with the fixed clamping plate, a first cylinder provided on the clamping frame for driving the adapter plate to slide, and a linkage structure provided between the active clamping plate and the driven clamping plate, wherein a gap is formed between the active clamping plate and the driven clamping plate for clamping the workpiece.

[0010] Furthermore, the linkage structure includes guide sleeves respectively fixed to the two ends of the driven clamping plate and guide slide bars respectively fixed to the two ends of the active clamping plate, and the free ends of the guide slide bars slide in the guide sleeves.

[0011] Furthermore, the rotation driving mechanism is specifically a first motor driving structure fixedly connected to the outside of the flip clamping frame on the same side as the active clamping plate.

[0012] Furthermore, vertical T-shaped guide rails are fixedly connected to both sides of the flip stand, and vertical T-shaped sliding grooves are provided on the inner side of the flip clamping frame for the vertical T-shaped guide rails to slide inside.

[0013] Furthermore, a threaded hole is opened between the two ends of the flip clamping frame, and the vertical driving structure includes a screw rotatably connected between the two ends of the flip frame and a second motor driving structure arranged on the flip frame and used to drive the screw to rotate. The screw passes through the threaded hole and is connected to the thread inside the threaded hole.

[0014] Furthermore, the length of the lead screw is equal to the length of the vertical T-shaped guide rail.

[0015] The principles and effects of this basic solution are:

[0016] Compared with the prior art, the utility model sequentially arranges the robot gripper assembly, the grabbing, lifting and flipping assembly, the horizontal servo transfer assembly and the servo grabbing and discharging assembly on the assembly line. After the robot gripper assembly places the spring pressure plate and the compression spring to be assembled on the end face of the battery module at one end of the assembly line and fixes them, the battery pack with one side installed is transported along the assembly line. The grabbing, lifting and flipping assembly flips the workpiece during the grabbing process, and after the flipping is completed, the workpiece is put back on the assembly line to be installed by the robot gripper assembly on the spring pressure plate and the compression spring at the other end of the battery module. During the installation process, there is no need to uniformly transport the battery modules. The grabbing, lifting and flipping assembly can be used to assemble the spring pressure plates and compression springs at both ends of the battery module during transportation. This solves the problem that in the traditional battery module assembly station, the workpiece that needs to be turned over and clamped needs to be flipped on the transfer table, which prolongs the assembly time of the battery module.
