Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a electrode group clamping device with an electrode tab tilting structure. Background Technology

[0002] A battery electrode group is typically assembled from positive plates, negative plates, and separators. In a storage battery, to achieve the battery's rated capacity, several plates of the same polarity are usually welded together in parallel to form a group, called a plate group or electrode assembly. Two groups of positive and negative plates are inserted into each other, with a separator inserted between them, to form a single storage battery cell.

[0003] Before welding the busbar, the outermost tabs of the battery electrode group are tilted to shorten the welding length of the busbar and reduce the amount of lead used.

[0004] During the transport of electrode groups, the battery production equipment is limited by factory space. The electrode groups are not transported by a single conveyor belt. Multiple conveyor belts are used to change the transport direction of the electrode groups, so that the electrode groups can reach multiple equipment for processing. The electrode groups are transferred by changing the conveyor belts through a robotic arm. The robotic arm transfers the electrode groups by clamping them. However, during the clamping process, it is not possible to tilt the tabs on both sides of the electrode group. This results in the electrode groups needing additional tilting operations in subsequent processes, which affects production efficiency. Utility Model Content

[0005] The main purpose of this utility model is to provide a pole group clamping device with a pole tab tilting structure. When the two jaws clamp the pole group, the two pressure blocks on the two jaws will contact the pole tabs on both sides of the pole group. As the two jaws approach each other, the pressure blocks will tilt the pole tabs, thus eliminating the need to tilt the pole tabs in subsequent processes and improving efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A pole group clamping device with a tab tilting structure includes a conveyor for conveying pole groups, a lifting device above the conveyor, and a number of clamping cylinders fixed to the bottom output end of the lifting device via a frame. The two clamping ends of the clamping cylinders are fixed with jaws, and the sides of the jaws clamping the pole groups are provided with pressure blocks for tilting the tabs.

[0008] Furthermore, the side of the gripper contacting the electrode group is provided with a sliding groove, the pressure block is slidably connected in the sliding groove, and an adjustment mechanism is also included, the adjustment mechanism being used to adjust the position of the pressure block in the sliding groove.

[0009] Furthermore, the adjusting mechanism includes a bearing and a screw. The bearing is fixed to the end of the pressure block away from the pole group, and the screw is threadedly connected to the clamp. One end of the screw is located in the sliding groove and fixed in the rotating ring of the bearing.

[0010] Furthermore, the gripper is also threaded with a locking screw, which is used to hold the screw in place.

[0011] Furthermore, the cross-section of the pressure block is rectangular.

[0012] Furthermore, the surface of the pressure block that contacts the electrode tab is an inclined surface, and the inclined surface is inclined in the direction of the upper end of the inclined surface towards the electrode tab.

[0013] Furthermore, the conveyor is a chain conveyor, and the conveyor belt of the conveyor is provided with a limiting plate for limiting the position of the pole group.

[0014] Furthermore, it also includes a positioning rod located below the clamping cylinder, and several of the grippers are slidably connected to the positioning rod through through slots. The positioning rod is connected to the frame through a connecting rod.

[0015] Furthermore, the lowering device is a cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the two jaws of this invention clamp the electrode group, the two pressure blocks on the two jaws will come into contact with the electrode tabs on both sides of the electrode group. As the two jaws approach each other, the pressure blocks will press the electrode tabs at an angle, thus eliminating the need to press the electrode tabs at an angle in subsequent processes and improving efficiency.

[0018] The adjustment mechanism of this utility model can adjust the length of the pressure block 9 extending out of the sliding groove 10, thereby adjusting the degree of tilt of the electrode ear after the pressure block tilts the electrode ear.

[0019] The locking screw of this invention can abut against the screw rod after rotation, thereby further preventing the screw rod from rotating and improving the stability of the pressure block.

[0020] The gripper of this invention moves on the positioning rod, which further limits the movement path of the gripper, ensuring that the movement path of the gripper does not change after long-term use. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-3 As shown, a pole group clamping device with a pole tab tilting structure includes a conveyor 7 for conveying pole groups, a lifting device 1 above the conveyor 7, and several clamping cylinders 3 fixed at the bottom output end of the lifting device 1 via a frame 2. The two clamping ends of the clamping cylinders 3 are fixed with grippers 6. The sides of the grippers 6 that clamp the pole groups are provided with pressure blocks 9 for tilting the pole tabs. The lifting device 1 is a cylinder.

[0027] In this embodiment, the conveyor 7 is a chain conveyor. The conveyor belt of the conveyor 7 is equipped with several limiting plates 8 for limiting the position of the electrode group. Two limiting plates 8 form a group, thereby initially positioning the electrode group. When the conveyor 7 transports the electrode group to the area below the corresponding gripper 6, the lifting device 1 is controlled to operate, which drives the gripper 6 to descend, so that the two grippers 6 on the same gripping cylinder 3 are respectively located on both sides of the electrode group. Then, the gripping cylinder 3 operates, so that the two grippers 6 approach each other, thereby gripping the electrode group. During this process, the two pressure blocks 9 on the two grippers 6 will contact the electrode ears on both sides of the electrode group. As the two grippers 6 approach each other, the pressure blocks 9 will tilt the electrode ears, thus eliminating the need to tilt the electrode ears in subsequent processes and improving efficiency.

[0028] Among them, such as Figure 2 As shown, the side of the contact electrode group of the gripper 6 is provided with a sliding groove 10, the pressure block 9 is slidably connected in the sliding groove 10, and also includes an adjustment mechanism. The adjustment mechanism is used to adjust the position of the pressure block 9 in the sliding groove 10, thereby adjusting the length of the pressure block 9 extending out of the sliding groove 10, and thus adjusting the degree of inclination of the pressure block 9 pressing the electrode tab.

[0029] Specifically, such as Figure 2 and Figure 3As shown, the adjustment mechanism includes a bearing 13 and a screw 11. The bearing 13 is fixed to the end of the pressure block 9 away from the electrode group. The screw 11 is threaded onto the jaw 6. One end of the screw 11 is located in the sliding groove 10 and fixed in the rotating ring of the bearing 13. The cross-section of the pressure block 9 is rectangular. The surface of the pressure block 9 that contacts the electrode ear is an inclined surface. The inclined surface is inclined towards the electrode ear from the upper end. It is restricted by the sliding groove 10 and cannot rotate. Since the screw 11 is rotatably connected to the pressure block 9 through the bearing 13, when the screw 11 rotates, the pressure block 9 will not rotate, but the pressure block 9 will move with the movement of the end of the screw 11, thereby changing the length of the pressure block 9 extending out of the sliding groove 10. Furthermore, when the pressure block 9 does not rotate, the inclined direction of its inclined surface will not change, so as to meet the requirement of pressing the electrode ear.

[0030] Among them, such as Figure 1 and Figure 2 As shown, a locking screw 12 is also threaded onto the gripper 6. After the locking screw 12 is rotated, it can abut against the screw 11, thereby further preventing the screw 11 from rotating and providing stability to the pressure block 9.

[0031] Among them, such as Figure 1 As shown, the device also includes a positioning rod 4, which is located below the clamping cylinder 3. Several grippers 6 are slidably connected to the positioning rod 4 through a through groove 601. The positioning rod 4 is connected to the frame 2 through a connecting rod 5. When the grippers 6 clamp the pole group, the grippers 6 will move on the positioning rod 4. The positioning rod 4 will provide a supporting force to the grippers 6 and further limit the movement path of the grippers 6 to ensure that the movement path of the grippers 6 will not change after long-term use.

[0032] Working principle: Conveyor 7 can transport the electrode group to the corresponding gripper 6. At this time, the operator controls the lifting device 1 to work, which can drive the gripper 6 to descend, so that the two grippers 6 on the same gripping cylinder 3 are respectively located on both sides of the electrode group. Then, the gripping cylinder 3 works to bring the two grippers 6 closer together, thereby gripping the electrode group. During this process, the two pressure blocks 9 on the two grippers 6 will contact the electrode ears on both sides of the electrode group. As the two grippers 6 approach, the pressure blocks 9 will tilt the electrode ears, thus eliminating the need to tilt the electrode ears in subsequent processes, improving efficiency. In addition, the position of the pressure blocks 9 can be adjusted by the adjustment mechanism to ensure that the tilt of the electrode ears meets the requirements after the pressure blocks 9 tilt the electrode ears.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
