Description

Technical Field

[0001] The utility model relates to the field of battery cell production equipment, in particular to an automatic bending and insulating tape pasting machine. Background Art

[0002] Although lithium-ion battery cells have the advantage of high energy density, their safety is also a matter of great concern. Therefore, it is necessary to weld a TCO component (THERMAL-CUTOFF, also known as a thermal fuse, thermal cut-off, or temperature fuse, etc.) on the positive electrode tab of the battery as a protection device. When the battery generates heat due to abnormal conditions during use, the heat is conducted to the TCO component. When the temperature is higher than the disconnection temperature of the TCO component, the TCO component will cut off the charging circuit to protect the battery; the TCO component is generally adhered to one end of the battery tab output by tape. During installation, it needs to be welded to the positive electrode tab first and then the tab of the TCO component is folded in half by bending. Currently, whether it is automatic assembly or manual operation, it will cause the bending size of the TCO to be unstable, resulting in easy deformation of the tab and ultimately affecting the relative position between the tabs. Summary of the Utility Model

[0003] Based on the above problems, the purpose of the utility model is to provide an automatic bending and insulating tape pasting machine with high production speed, high efficiency, which can effectively reduce the unstable size and easy deformation during the bending of the TCO tab, and has a high degree of automation.

[0004] In view of the above problems, the following technical solutions are provided: an automatic bending and insulating tape pasting machine, including a frame, a turntable with multiple clamping stations is arranged on the frame, a TCO bending station corresponding to one of the clamping stations is arranged on the frame, a three-axis deviation correction mechanism and a rotating mechanism driven by it to achieve displacement in space are arranged at the TCO bending station, a tab gripper driven by a tab clamping element is arranged at the output end of the rotating mechanism, a bending point positioning mechanism, a TCO pre-pressing mechanism and a bending CCD sensor are also arranged at the TCO bending station, the TCO pre-pressing mechanism includes a lower support mechanism and an upper pre-pressing mechanism, a lower support assembly that can move up and down is arranged on the lower support mechanism, an upper pre-pressing assembly that can slide horizontally and move up and down is arranged on the upper pre-pressing mechanism, the lower support assembly contacts the lower surface position of the battery tab when moving upward, and the upper pre-pressing assembly contacts the upper surface position of the bent TCO tab when moving downward.

[0005] In the above structure, the three-axis alignment mechanism controls the rotation mechanism to displace in space, indirectly controlling the position of the tab gripper in space. During operation, the bending point positioning mechanism presses the bending point of the TCO (to prevent the other parts of the battery cell from being involved during later bending, resulting in unstable bending dimensions of the TCO and easy deformation). The tab gripper holds the TCO tab, and the bending CCD sensor assists in taking pictures. The three-axis alignment mechanism controls the tab gripper to perform front-back correction in the X-axis. Then, the rotation mechanism rotates to the Z-axis rotation position to bend the TCO tab. The bending CCD sensor takes pictures again for assistance. The three-axis alignment mechanism controls the left-right correction in the Y-axis. The Z-axis moves to the gluing position of the TCO. Then, the lower support assembly and the upper pre-pressing assembly approach each other to tightly press and bond the glue surface, completing the bending of the TCO. By adding a bending CCD sensor as a vision system, real-time correction and alignment can be performed. Using a three-axis alignment mechanism can meet the accuracy requirements, ensure stable dimensions after bending, have a fast production speed, high efficiency, high automation, effectively reduce the situation of unstable dimensions and easy deformation when bending the TCO tab, and also have the advantages of simple maintenance and convenient debugging, solving the disadvantages of the existing system without a vision system, insufficient accuracy of using cylinders, cumbersome debugging, and difficult maintenance.

[0006] The present utility model is further configured such that the frame further includes a feeding manipulator, a secondary positioning platform, a loading manipulator, an unloading manipulator, a transfer platform, an unloading manipulator, a good product output mechanism, and a defective product output mechanism; the secondary positioning platform is provided with a lateral positioning push block and a longitudinal positioning push block; the feeding manipulator places the battery cell on the secondary positioning platform. After being pushed and positioned by the lateral positioning push block and the longitudinal positioning push block, the loading manipulator transfers the battery cell to the clamping station; the unloading manipulator transfers the battery cell that has completed the production process at the clamping station to the transfer platform, and then the unloading manipulator classifies and places the battery cell on the good product output mechanism or the defective product output mechanism.

[0007] In the above structure, the feeding manipulator, the secondary positioning platform, and the loading manipulator cooperate with each other to ensure that the position of the battery cell grasped and placed on the clamping station by the loading manipulator always remains the same; the unloading manipulator, the transfer platform, and the unloading manipulator cooperate with each other to ensure that the battery cells can be reasonably classified and each working step reaches the best matching state.

[0008] The present utility model is further configured such that the clamping station and the transfer platform are both negative pressure adsorption jigs; the clamping parts of the feeding manipulator, the loading manipulator, the unloading manipulator, and the unloading manipulator are all negative pressure adsorption jigs.

[0009] In the above structure, the negative pressure adsorption jig can avoid displacement during fixation, ensure the positioning accuracy, and also avoid damage to the battery cell.

[0010] The present utility model is further configured such that the bent CCD sensor is located above the clamping station of the TCO bending station.

[0011] In the above structure, it can ensure accurate alignment to take pictures of the electrode tabs of the battery cell and the TCO.

[0012] The present utility model is further configured such that the bending point positioning mechanism is provided with a positioning probe that can slide horizontally and move up and down. The long direction of the positioning probe is the same as the length direction of the electrode tabs of the battery cell and the TCO. When the positioning probe slides horizontally, the sliding direction is the same as the length direction of the positioning probe or the electrode tabs of the battery cell and the TCO. When the positioning probe is positioned, it is located above the TCO of the battery cell and inside the bending direction of the TCO electrode tab, pressing the TCO onto the lower support assembly.

[0013] In the above structure, the positioning probe presses down to fix the TCO, so that when the TCO electrode tab is bent, elastic pulling can be avoided, which affects the bending consistency. At the same time, it can also assist in reducing the influence on the position of the battery cell during bending.

[0014] The present utility model is further configured such that the midline of the clamping surface of the electrode tab gripper is parallel to the axis of rotation of the rotating mechanism and is offset.

[0015] In the above structure, it is ensured that the electrode tab gripper drives the TCO electrode tab to present an arc-drawing action rather than rotation during bending.

[0016] The present utility model is further configured such that a silica gel layer is provided on the clamping surface of the electrode tab gripper.

[0017] In the above structure, the clamping surface of the electrode tab gripper is increased with anti-slip and wear-resistant silica gel, making its clamping stable, the angle stable during bending and flipping, and avoiding deformation of the TCO electrode tab.

[0018] The present utility model is further configured such that the movement of the X, Y, and Z axes of the three-axis deviation correction mechanism is driven by a stepping motor or a servo motor.

[0019] In the above structure, the control accuracy can be effectively ensured.

[0020] The present utility model is further configured such that the frame is further provided with a release-type paper station, a measured release-type paper station, a TCO pressure-holding station, a dog-ear shaping station, a sticker pasting station, a sticker pressure-holding station, a sticker wrapping station, a dog-ear sticker shaping and pressure-holding station, a TCO height measurement station, and a dimension measurement and blanking station arranged in sequence along the rotation direction of the turntable. The TCO bending station is located between the measured release-type paper station and the TCO pressure-holding station.

[0021] In the above structure, it is possible to not turn over the incoming battery cells, automatically tear the release paper on the TCO and detect it; automatically bend the TCO guided by the bending CCD sensor, and the pressure and time for maintaining pressure on the TCO after bending are visible and adjustable; shape the dog ears based on the edge of the battery cell; supply materials through the sticker feeder and automatically stick the sticker; wrap the U-shaped sticker, and the pressure for maintaining pressure after wrapping is visible and adjustable; fold the dog ears based on the edge of the battery cell; check the height of the TCO based on the surface of the battery cell, and use the camera to check the F1 size.

[0022] The present utility model is further configured such that the loading manipulator clamps and places the battery cell on the clamping station between the release paper tearing station and the size measurement and unloading station; the unloading manipulator transfers the battery cell from the clamping station of the size measurement and unloading station to the transfer platform.

[0023] The beneficial effects of the present utility model are as follows: The three-axis alignment mechanism controls the rotation mechanism to displace in space, indirectly controlling the position of the tab gripper in space; during operation, the bending point positioning mechanism presses the bending point of the TCO (to avoid affecting other parts of the battery cell during subsequent bending, resulting in unstable TCO bending dimensions and easy deformation), the tab gripper clamps the TCO tab, the bending CCD sensor assists in taking pictures, the three-axis alignment mechanism controls the tab gripper to perform front and back correction in the X-axis, and then the rotation mechanism rotates to the Z-axis rotation position to bend the TCO tab. The bending CCD sensor takes pictures again for assistance, the three-axis alignment mechanism controls the left and right correction in the Y-axis, the Z-axis moves to the sticker application position of the TCO, and then the lower support assembly and the upper pre-pressing assembly approach each other to tightly press and fit the adhesive surface, completing the bending of the TCO; by adding a bending CCD sensor as the vision system, real-time correction and alignment can be performed. Using the three-axis alignment mechanism can meet the accuracy requirements, ensure stable dimensions after bending, have a fast production speed, high efficiency, high automation degree, effectively reduce the situation where the dimensions of the TCO tab are unstable and easy to deform during bending, and also have the advantages of simple maintenance and convenient debugging, solving the drawbacks of the existing non-vision system, insufficient accuracy of using cylinders, cumbersome debugging, and difficult maintenance.

The bending CCD sensor 26 assists in taking pictures again, the three-axis alignment mechanism 21 controls the left-right correction in the Y-axis, the Z-axis moves to the gluing position of the TCO, and then the lower support assembly 2511 and the upper pre-pressing assembly 2521 approach each other to tightly press and bond the glue surface, completing the bending of the TCO; by adding the bending CCD sensor 26 as a vision system, real-time correction and alignment can be performed. Using the three-axis alignment mechanism 21 can meet the accuracy requirements, ensure stable dimensions after bending, has a fast production speed, high efficiency, high automation, can effectively reduce the situation where the dimensions of the TCO tab c are unstable and prone to deformation during bending, and also has the advantages of simple maintenance and convenient debugging, solving the disadvantages of the existing non-vision system, insufficient accuracy of using cylinders, cumbersome debugging, and difficult maintenance.
