Description

Technical Field

[0001] This utility model relates to the technical field of battery cell welding equipment, specifically a welding fixture for a winding machine. Background Technology

[0002] The main components of a battery cell include the core material, positive and negative electrode protection sheets, battery cell casing, and sealing plate. These components are usually connected by welding. As the industry's requirements for the performance of energy storage devices increase, adding aluminum foil welding to the welding of tabs and electrode sheets can effectively improve conductivity and heat dissipation. However, existing welding fixtures are difficult to meet the requirements of welding three materials at the same time.

[0003] On the one hand, traditional tooling lacks a dedicated aluminum foil feeding mechanism. After adding the aluminum foil feeding function, it is difficult to accurately deliver and position the aluminum foil, which can easily lead to deviation and wrinkles, affecting the welding quality. On the other hand, the original welding positioning structure is only designed for two materials. When three materials are superimposed, the positioning accuracy is insufficient, resulting in welding position deviation and an increase in scrap rate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a welding fixture for a winding machine, which has the advantages of feeding aluminum foil sheets and precise positioning, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a welding fixture for a winding machine, comprising a base plate, a lower welding seat fixed on the upper surface of the base plate, and a conveying assembly for conveying aluminum foil and a correction assembly for correcting the position of the aluminum foil on the upper surface of the base plate, wherein the conveying assembly is located on the right side of the lower welding seat and the correction assembly is located on the left side of the lower welding seat.

[0006] The correction assembly includes a correction moving base, which is slidably connected to a base plate. A support plate is provided above the correction moving base. Two sets of positioning judgment modules are installed on the bottom surface of the support plate, including a mounting block and a laser generator and a correspondingly tilted light receiver. A fixed base is installed between the two sets of judgment modules. A correction wheel is installed on the inner wall of the fixed base. A correction motor is installed on the side of the fixed base. The output end of the correction motor is connected to the correction wheel.

[0007] Furthermore, a T-shaped groove is provided on the bottom surface of the bearing plate, and a T-shaped block is fixed on the upper surface of the mounting block, with the T-shaped block slidably connected to the T-shaped groove.

[0008] The above solution allows the mounting block to be moved left and right by sliding connection between the T-block and the T-slot, thus adapting to aluminum foil sheets of different sizes.

[0009] Furthermore, the conveying assembly includes a conveying movable seat, a conveying lifting platform is mounted on the upper surface of the conveying movable seat, a bracket is fixed to the side of the conveying lifting platform, and a vacuum suction cup is mounted on the bottom surface of the bracket.

[0010] The above method uses a vacuum suction cup to pick up aluminum foil sheets, which, together with the conveyor moving seat and the conveyor lifting platform, are transferred to the upper surface of the lower welding seat.

[0011] Furthermore, a first servo motor is mounted on the upper surface of the base plate, a first lead screw is mounted on the output end of the first servo motor, the first lead screw is threadedly connected to the conveying moving seat, a linear guide rail is fixed on the upper surface of the base plate, and the conveying moving seat is slidably connected to the linear guide rail.

[0012] With the above scheme, the first servo motor can drive the first lead screw to rotate, thereby driving the conveying moving seat to move on the upper surface of the linear guide rail.

[0013] Furthermore, a second servo motor is mounted on the upper surface of the base plate, and a second lead screw is mounted on the output end of the second servo motor. The second lead screw is threadedly connected to the correction moving seat, and the correction moving seat is slidably connected to the linear guide rail.

[0014] With the above scheme, the second servo motor can drive the second lead screw to rotate, thereby causing the correction moving seat to move on the upper surface of the linear guide rail.

[0015] Furthermore, the upper surface of the correction moving seat is provided with a correction lifting platform, and the side of the correction lifting platform is fixed to the bearing plate.

[0016] The above solution allows the support plate to be raised and lowered via the alignment lifting platform.

[0017] Furthermore, two symmetrically arranged side plates are fixed on the upper surface of the base plate, and each side plate is provided with a lifting roller lifting cylinder, the output end of which is equipped with a lifting roller body.

[0018] The above scheme uses a lifting cylinder to move the lifting roller body up and down.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0020] This type of welding fixture for a winding machine uses a conveying component to transport aluminum foil to a lower welding base. Then, a correction component corrects the aluminum foil on the upper surface of the lower welding base. A laser generator emits light that shines on the upper surface of the lower welding base. If the aluminum foil is misaligned, it will move to the position illuminated by the light. Due to the good reflectivity of the aluminum foil, the light is reflected to a light receiver. The light receiver receives the refracted light and determines that a misalignment has occurred. The correction motor drives the correction wheel to correct the aluminum foil, thereby achieving the delivery and precise positioning of the aluminum foil. Attached Figure Description

A fixed base 404 is installed between the two sets of judgment modules. A correction wheel 405 is installed on the inner wall of the fixed base 404. A correction motor 406 is installed on the side of the fixed base 404. The output end of the correction motor 406 is connected to the correction wheel 405.

[0034] Please see Figure 1 , Figure 3 and Figure 4 The bottom surface of the bearing plate 402 is provided with a T-slot 407, and a T-block is fixed on the upper surface of the mounting block 4031. The T-block is slidably connected to the T-slot 407. Through the sliding connection between the T-block and the T-slot 407, the mounting block 4031 can be adjusted to move left and right to adapt to aluminum foil sheets of different sizes. The conveying assembly 3 includes a conveying moving seat 301. A conveying lifting platform 302 is installed on the upper surface of the conveying moving seat 301. A bracket 303 is fixed on the side of the conveying lifting platform 302. A vacuum suction cup 304 is installed on the bottom surface of the bracket 303. The vacuum suction cup 304 can adsorb aluminum foil sheets. In conjunction with the conveying moving seat 301 and the conveying lifting platform 302, the aluminum foil sheets are transferred to the upper surface of the lower welding seat 2.

[0035] Please see Figure 1 , Figure 4 and Figure 5A first servo motor 5 is mounted on the upper surface of the base plate 1. A first lead screw 6 is mounted on the output end of the first servo motor 5. The first lead screw 6 is threadedly connected to the conveying moving seat 301. A linear guide rail 7 is fixed on the upper surface of the base plate 1. The conveying moving seat 301 is slidably connected to the linear guide rail 7. The first servo motor 5 can drive the first lead screw 6 to rotate, thereby driving the conveying moving seat 301 to move on the upper surface of the linear guide rail 7. A second servo motor 8 is mounted on the upper surface of the base plate 1. A second lead screw 9 is mounted on the output end of the second servo motor 8. The second lead screw 9 is threadedly connected to the correction moving seat 401. The correction moving seat 401 is slidably connected to the linear guide rail 7. The second servo motor 8 can drive the second lead screw 9 to rotate, thereby driving the correction moving seat 401 to move on the upper surface of the linear guide rail 7.

[0036] Please see Figure 1 , Figure 4 and Figure 5 The upper surface of the correction moving seat 401 is provided with a correction lifting platform 408. The side of the correction lifting platform 408 is fixed to the bearing plate 402. The bearing plate 402 can be lifted and lowered by the correction lifting platform 408. Two symmetrically arranged side plates 10 are fixed on the upper surface of the base plate 1. Each side plate 10 is provided with a lifting roller cylinder 11. The output end of the lifting roller cylinder 11 is equipped with a lifting roller body 12. The lifting roller body 12 is lifted and lowered by the lifting roller cylinder 11.

[0037] It should be noted that after the correction is completed, the bearing plate 402 moves away from the lower welding seat 2 under the action of the correction moving seat 401 and the correction lifting platform 408, so as to avoid affecting the subsequent welding operation.

[0038] The working principle of the above embodiment is as follows: During use, the first servo motor 5 drives the first lead screw 6 to rotate, thereby driving the conveying moving seat 301 to move. The movement of the conveying moving seat 301 and the conveying lifting platform 302 drives the support 303 to move. The movement of the support 303 drives the vacuum suction cup 304 to move. The vacuum suction cup 304 drives the aluminum foil to move and transfer the aluminum foil to the upper surface of the lower welding seat 2.

[0039] Next, the second servo motor 8 drives the second lead screw 9 to rotate. The rotation of the second lead screw 9 drives the correction moving seat 401 to move. At the same time, the correction lifting platform 408 on the upper surface of the correction moving seat 401 drives the support plate 402 to move. The support plate 402 moves to the top of the lower welding seat 2. Before this, the positioning judgment module 403 moves to adapt to the size of the existing aluminum foil. The laser generator 4032 emits light to illuminate the upper surface of the lower welding seat 2. If the aluminum foil is offset, the aluminum foil will move to the position illuminated by the light. Due to the good reflectivity of the aluminum foil, the light is reflected to the light receiver 4033. The light receiver 4033 receives the refracted light and judges that the offset has occurred. The correction motor 406 drives the correction wheel 405 to correct the aluminum foil, thereby realizing the delivery and precise positioning of the aluminum foil.
