Description

Technical Field

[0001] The utility model relates to the technical field of battery core winding, in particular to a cylindrical battery core winding mechanism. Background Art

[0002] Battery cells are divided into three types: aluminum shell battery cells, soft-pack battery cells, and cylindrical battery cells. Mobile phone batteries usually use aluminum shell battery cells, digital products such as Bluetooth mostly use soft-pack battery cells, and laptop batteries use a series-parallel combination of cylindrical battery cells. Existing cylindrical battery cells are usually wound with two layers of diaphragms and positive and negative electrode materials. The positive and negative electrode materials are separated by a diaphragm and finally wrapped with an outer film.

[0003] In the existing technology, such as the document with publication number CN218568913U, a cylindrical battery cell winding mechanism is specifically disclosed. In this document, the device is arranged by a vertical plate two and two rotating rods. By moving the vertical plate two, the vertical plate two is separated from the blocking of the wound battery cell, so that the battery cell can be removed. However, when the vertical plate two is removed from the rotating rod, the end of the rotating rod lacks a support member and is subjected to the pressure of the battery cell. Over time, the rotating rod will bend, causing the rotating rod to swing when it rotates later, which is not conducive to the installation and removal of the battery cell. For this reason, we propose a cylindrical battery cell winding mechanism. Utility Model Content

[0004] The utility model proposes a cylindrical battery cell winding mechanism, which solves the technical problem in the prior art that a second vertical plate is sleeved with two rotating rods, and the second vertical plate is moved so that the second vertical plate is detached from blocking the wound battery cell, thereby enabling the battery cell to be removed. However, when the second vertical plate is removed from the rotating rod, the end of the rotating rod lacks a support member and is subjected to the pressure of the battery cell. Over time, the rotating rod will bend, resulting in the rotating rod swinging when it is rotated at a later stage, which is not conducive to the installation and removal of the battery cell.

[0005] The utility model proposes a cylindrical battery cell winding mechanism, comprising a base, a sliding component installed on the top of the base, two bottom plates installed on the top of the sliding component, limit sleeves are provided above the two bottom plates, the circumferential outer walls of the two limit sleeves are symmetrically structured and fixed with two support plates, and a connecting plate is fixed on the relatively close side of the two support plates.

[0006] Furthermore, the sliding assembly includes a hydraulic rod and a sliding seat, the hydraulic rod is fixedly connected to the inner wall of the base, and the sliding seat is slidably connected to the inner wall of the base.

[0007] Furthermore, a limiting groove is provided on the top of the slide seat, a bidirectional threaded rod is rotatably connected to the inner wall of the limiting groove, two sliding blocks are slidably connected to the inner wall of the limiting groove, both ends of the bidirectional threaded rod pass through the sliding blocks respectively and are threadedly connected to the sliding blocks, a motor is fixedly provided on the outer wall of the slide seat, and the output end of the motor is fixedly connected to the bidirectional threaded rod.

[0008] Furthermore, a slide groove is provided on the top of the base, the hydraulic rod is located in the slide groove and is fixedly connected to the inner wall thereof, and the slide seat is located on the inner wall of the slide groove and is slidably connected to the inner wall thereof.

[0009] Furthermore, a mounting plate is fixedly provided on the top of the base, a machine base is fixedly provided on the outer wall of the mounting plate, a second motor is fixedly provided on the top of the machine base, a rotating disk is rotatably connected to the inner wall of the mounting plate, an output end of the second motor is fixedly connected to the rotating disk, a mounting shaft is fixedly provided on the inner wall of the rotating disk, and the mounting shaft passes through two limit sleeves and is slidably connected thereto.

[0010] Furthermore, a support plate is fixedly provided on the top of one of the base plates, and the bottom of the support plate is in sliding contact with the top of the other base plate.

[0011] Furthermore, two fixing plates are fixedly arranged on the top of the base in a symmetrical structure, and two guide rods are fixedly arranged on one side of the two fixing plates that are relatively close to each other in a symmetrical structure, and the ends of the two guide rods penetrate through the two bottom plates and are slidably connected thereto.

[0012] The beneficial effects of the present invention are:

[0013] 1. Start the second motor to drive the installation shaft to rotate counterclockwise, so that the diaphragm, positive and negative electrode materials can be wound together. After the winding is completed, the hydraulic rod pushes the slide to move, and the slide drives the two limit sleeves to move until the two limit sleeves are moved out of the installation shaft.

The outer walls of the two limit sleeves 12 are symmetrically structured and fixed with two support plates 10, and a connecting plate 11 is fixed on the side where the two support plates 10 are relatively close to each other. The sliding assembly comprises a hydraulic rod 3 and a slide seat 4, the hydraulic rod 3 is connected and fixed to the inner wall of the base 1, the slide seat 4 is slidably connected to the inner wall of the base 1, a limit groove 5 is arranged on the top of the slide seat 4, a bidirectional threaded rod 8 is rotatably connected to the inner wall of the limit groove 5, and two sliders 6 are slidably connected to the inner wall of the limit groove 5, and the two ends of the bidirectional threaded rod 8 respectively penetrate the slider 6 and are threadedly connected thereto, and a motor 7 is fixed on the outer wall of the slide seat 4. The output end of the motor 1 7 is connected and fixed to the bidirectional threaded rod 8, a slide groove 2 is opened on the top of the base 1, the hydraulic rod 3 is located in the slide groove 2 and is connected and fixed with its inner wall, the slide seat 4 is located on the inner wall of the slide groove 2 and is slidably connected with its inner wall, and the starting motor 2 19 drives the installation shaft 20 to rotate counterclockwise, so that the diaphragm and the positive and negative electrode materials can be wound together. After the winding is completed, the hydraulic rod 3 pushes the slide seat 4 to move, and the two limit sleeves 12 are driven to move by the slide seat 4 until the two limit sleeves 12 are removed from the installation shaft 20. When the two limit sleeves 12 move, the battery cells on the installation shaft 20 can be pushed out, which is convenient for the operator to take out the battery cells. This design can effectively support the installation shaft 20 during the installation and removal of the battery cells to prevent the installation shaft 20 from bending.

[0023] like Figure 1 and Figure 4 As shown, a mounting plate 16 is fixedly provided on the top of the base 1, a machine base 18 is fixedly provided on the outer wall of the mounting plate 16, a motor 19 is fixedly provided on the top of the machine base 18, a rotating disk 17 is rotatably connected to the inner wall of the mounting plate 16, an output end of the motor 19 is fixedly connected to the rotating disk 17, a mounting shaft 20 is fixedly provided on the inner wall of the rotating disk 17, and the mounting shaft 20 passes through the two limit sleeves 12 and is slidably connected thereto.

The ends of the two guide rods 14 both penetrate the two bottom plates 9 and are slidably connected thereto.

[0025] Working principle: The two-way threaded rod 8 is driven to rotate by the motor 1 7, so that the two sliders 6 move to the two ends of the two-way threaded rod 8 respectively, and the bottom plate 9 is driven to move by the two sliders 6 respectively, so that the distance between the two limit sleeves 12 can be adjusted, and the diaphragm is passed through the middle seam of the installation shaft 20 and folded in half. The motor 2 19 drives the rotating disk 17 to rotate, so that the installation shaft 20 rotates counterclockwise for one circle and then stops. At this time, the negative electrode material is inserted between the folded diaphragms, so that the rear end of the negative electrode material is gradually laid forward from the rear end of the diaphragm close to the installation shaft 20 , and then place the positive electrode material on the top layer of the diaphragm, and the rear end of the positive electrode material is tightly inserted between the installation shaft 20 and the diaphragm.

When the two limit sleeves 12 move, the battery cell on the installation shaft 20 can be pushed out, which is convenient for the operator to take out the battery cell.
