Description

A low-cost and high-efficiency texturing equipment Technical Field

[0001] The utility model relates to the technical field of battery core production, in particular to a low-cost and high-efficiency texturing device. Background Art

[0002] With the growth in electric vehicle sales, the market demand for power batteries has increased significantly. With China's strong advocacy for low-carbon, green energy, the widespread application of photovoltaic and wind power generation is underway. Due to the instability of photovoltaic and wind power generation, a large number of energy storage batteries are needed to store green electricity. Furthermore, in areas where peak and valley electricity prices vary significantly, valley electricity can be stored and discharged during peak demand, improving grid power quality, regulating electricity demand, and smoothing peak and valley demand. For these reasons, the market demand for power batteries and energy storage batteries has skyrocketed.

[0003] A battery cell is a small, independent battery. Many cells are connected in series and parallel to form a battery module. Whether cylindrical or square, insulation is required between cells and between the cells and the tray. The cell casing insulation must meet certain requirements. Otherwise, leakage could lead to thermal runaway and a safety incident. Currently, most cell casing insulation is coated with a blue film, but its insulation, thermal conductivity, and production efficiency are inferior to emerging insulating coating spraying technologies. Because the aluminum casing of the battery cell is very shiny and has poor surface adhesion, it needs to be roughened before spraying to enhance the coating's adhesion.

[0004] At present, most of the cell casings are roughened using laser texturing. However, when using laser texturing, a laser is needed to make pits on the outer wall of the cell casing. On the one hand, the manufacturing cost of the laser itself is high. On the other hand, laser texturing also requires other auxiliary equipment. For example, laser ablation and engraving will produce smoke and dust, requiring customized smoke collectors, high-power fans, air ducts, purification equipment, etc., which will greatly increase the production line manufacturing cost, thereby increasing the manufacturing cost of the battery cell.

[0028] Example 1:

[0029] An embodiment of the present utility model provides a low-cost and high-efficiency texturing device, as shown in Figures 1 to 6, comprising: a longitudinal knurling device 1 and a transverse knurling device 2 arranged in sequence, the longitudinal knurling device 1 comprising a first conveying device 3 and a first mounting frame 4, a plurality of first jigs 5 are arranged on the first conveying device 3, the first mounting frame 4 is mounted above the first conveying device 3, a top surface texturing mechanism 6 is arranged on the top of the first mounting frame 4, edge texturing mechanisms 7 are symmetrically arranged on the front and back sides near the top of the first mounting frame 4, and first side texturing mechanisms 8 are symmetrically arranged on the front and back sides of the first mounting frame 4, the transverse knurling device 2 comprises a second conveying device 9 and a second mounting frame 10, a plurality of second jigs 11 are arranged on the second conveying device 9, the second mounting frame 10 is mounted above the second conveying device 9, and second side texturing mechanisms 12 are symmetrically arranged on the front and back sides of the second mounting frame 10.

[0030] The working principle and beneficial effects of the above technical solution are as follows: Traditional cell shell texturing usually uses laser to carve pits in the cell shell, but the laser is relatively expensive and has the following specific disadvantages:

[0031] 1. High manufacturing costs. On a 24-cell automatic spray coating line, the line speed is very high (up to 400mm / s at a 50JPM cycle, for example). Ordinary laser galvanometers cannot keep up, resulting in insufficient density of small dimples carved into the cell shells. High-speed galvanometer lasers are required, resulting in high manufacturing costs. A single 24-cell automatic spray coating line requires at least 10 high-speed galvanometer lasers, costing up to 10 million RMB. Furthermore, laser ablation and engraving generate smoke and dust, requiring custom smoke collectors, high-power fans, air ducts, and purification equipment, further increasing production line costs.

[0032] 2. Due to the limitation of the laser galvanometer frequency, when the line speed increases, the density of the small pits engraved by the laser will decrease, thereby reducing the adhesion of the coating.

[0033] 3. The performance of the laser will gradually decay. When it decays to a certain extent, the texturing effect cannot meet the demand and is difficult to be discovered, which can easily cause batch quality accidents.

[0034] 4. Lasers have high energy consumption. Typically, a single laser has a power of 1500W, 10 sets consume 15KW, and the energy consumption of the extraction and purification equipment is about 10KW, for a total of 24KW.

[0035] 5. High maintenance costs. The laser is cooled by water, which requires manual refilling of purified water from time to time. When the laser attenuates to the point where it no longer meets production requirements, the cost of repair or replacement is high.

[0036] Therefore, the utility model provides a low-cost and high-efficiency texturing equipment for solving the problem of high cost of the above-mentioned laser texturing treatment. Specifically, it comprises a longitudinal knurling device 1 and a transverse knurling device 2 arranged in sequence, the longitudinal knurling device 1 comprises a first conveying device 3 and a first mounting frame 4, a plurality of first jigs 5 are arranged on the first conveying device 3, the transverse knurling device 2 comprises a second conveying device 9 and a second mounting frame 10, a plurality of second jigs 11 are arranged on the second conveying device 9, the first conveying device 3 and the second conveying device 9 both adopt the existing battery cell 24 conveyor belt, the first mounting frame 4 and the second mounting frame 10 can be a door-type frame or connected by a plurality of door-type frames, the battery cell shell has six surfaces: front, back, left, right, top and bottom. When the battery cell shell is texturing, the battery cell 24 is first placed on the first jig 5 by a robot, and the first jig 5 moves with the first conveying device 3. When the second jig 5 with the battery cell 24 is moved, the battery cell 24 is placed on the first jig 5. When a jig 5 reaches the first mounting rack 4, as the battery cell 24 passes through, the top surface texturing mechanism 6 of the longitudinal knurling device 1 can texturing the upper surface of the battery cell shell, and the first side texturing mechanism 8 can texturing the front and rear surfaces of the battery cell shell. Then, the edge texturing mechanism 7 can texturing the front and rear edges of the upper end of the battery cell shell. After the battery cell 24 passes through the first mounting rack 4, the battery cell 24 is removed from the first jig 5 by a manipulator and placed in the second jig 11. The second conveying device 9 drives the second jig 11 to move toward the second mounting rack 10. When the battery cell 24 passes through the second mounting rack 10, the second side texturing mechanism 12 can texturing the left and right surfaces of the battery cell shell. The longitudinal knurling device 1 can achieve knurling on different surfaces of the outer wall of the battery cell shell through the top surface texturing mechanism 6, the edge texturing mechanism 7, and the first side texturing mechanism 8, thereby improving the texturing efficiency.

[0037] In the utility model, the longitudinal knurling device 1 and the transverse knurling device 2 replace the laser, which greatly reduces the manufacturing cost and the use cost of the battery cell 24 aluminum shell texturing equipment, and the longitudinal knurling device 1 and the transverse knurling device 2 are powered by the first conveying device 3 and the second conveying device 9 respectively, and no additional power equipment is required, which reduces the energy consumption of the texturing equipment. The longitudinal knurling device 1 and the transverse knurling device 2 realize the texturing of the battery cell shell surface by knurling, and the processing method is mechanical cold processing. No waste such as metal chips or metal particles is generated during the processing, and no waste recovery equipment is required; and there is no smoke and dust in the processing process, and no smoke and dust collection device, fan, purification equipment, etc. are required. The production process is green and environmentally friendly, which further reduces the manufacturing cost of the battery cell 24.

[0039] On the basis of the above-mentioned embodiment 1, as shown in FIG1 , a first clamping plate 13 is symmetrically provided on the first fixture 5 , and a stopper 14 is provided on the right side of the first clamping plate 13 .

[0040] The working principle and beneficial effects of the above technical solution are as follows: when the battery cell 24 is placed on the first jig 5, the first jig 5 moves from right to left, and the front and rear side surfaces of the battery cell shell respectively contact the first clamping plates 13 on the front and rear sides, and the length direction of the first clamping plate 13 is parallel to the forward direction of the first jig 5. A stopper 14 is provided on the right side of the first clamping plate 13. When the first jig 5 passes through the first conveying device 3, the stopper 14 can support the battery cell 24, thereby overcoming the resistance of the hob 21, so that the battery cell 24 moves forward under the push of the first conveying device 3 and completes the texturizing process.

[0041] Example 3

[0042] On the basis of embodiment 1 or 2, as shown in FIG4 , second clamping plates 15 are symmetrically provided on the left and right sides of the second fixture 11 .

[0043] The working principle and beneficial effects of the above technical solution are as follows: when the battery cell 24 is placed on the second jig 11, the second jig 11 moves from right to left, and the length direction of the second clamping plate 15 is perpendicular to the forward direction of the second jig 11. At this time, the front and rear surfaces of the battery cell shell are still in contact with the second clamping plate 15. The two second clamping plates 15 clamp the battery cell 24 on the second jig 11, and the left and right surfaces of the battery cell shell are exposed. As the second jig 11 passes through the second mounting frame 10, the left and right surfaces of the battery cell shell are respectively in contact with the second side texturing mechanism 12, thereby completing the texturing treatment of the left and right surfaces of the battery cell shell.

[0047] The angle between the fixing plate 16 of the top surface texturing mechanism 6 and the fixing plate 16 of the edge texturing mechanism 7 is 45°.

[0048] The working principle and beneficial effects of the above technical solution are as follows: the top surface texturing mechanism 6, the edge texturing mechanism 7, the first side texturing mechanism 8, and the second side texturing mechanism 12 all include a fixed plate 16 and a plurality of texturing components installed on the fixed plate 16. The output ends of the texturing components are all aligned with the battery cell shell. The texturing components can texturize the outer wall of the battery cell shell. The number of texturizing components is set according to the area of ​​the battery cell shell, so that the texturizing components can fully texturize the outer wall of the battery cell shell. Specifically, the fixed plate 16 of the top surface texturing mechanism 6 is horizontally installed at the top of the first mounting bracket 4. When the battery cell shell passes through the first mounting bracket 4, the texturizing component of the top surface texturing mechanism 6 can texturize the upper surface of the battery cell shell. The fixed plate 16 of the edge texturing mechanism 7 is tilted. The fixed plate of the edge texturing mechanism 7 The angle between 16 and the fixing plate 16 of the top surface texturing mechanism 6 can be set according to the edge of the battery cell shell. Preferably, the angle between the fixing plate 16 of the top surface texturing mechanism 6 and the fixing plate 16 of the edge texturing mechanism 7 is 45°, and the texturing component of the edge texturing mechanism 7 texturizes the front and rear edges of the upper end of the battery cell shell. The fixing plate 16 of the first side texturing mechanism 8 is vertically arranged on the front and rear sides of the first mounting bracket 4, and the texturizing components of the first side texturing mechanism 8 texturize the front and rear surfaces of the battery cell shell respectively. The fixing plate 16 of the second side texturizing mechanism 12 is vertically set and corresponds to the left and right surfaces of the battery cell shell. When the second fixture 11 with the battery cell 24 passes through the second mounting bracket 10, the texturizing component of the second side texturizing mechanism 12 can texturize the left and right surfaces of the battery cell shell.

[0049] Example 6

[0050] On the basis of Example 4, as shown in Figure 6, the texturing assembly includes a sliding rod 17, a sliding sleeve 18, a connecting spring 19, a fixing frame 20 and a hob 21. The sliding rod 17 is arranged on the side of the fixing plate 16 close to the battery core 24. The sliding rod 17 is perpendicular to the fixing plate 16. One end of the sliding rod 17 is fixedly connected to the fixing plate 16. The other end of the sliding rod 17 is provided with a sliding sleeve 18. The sliding sleeve 18 is sleeved on the outer wall of the sliding rod 17. The outer wall of the sliding rod 17 is slidably connected to the inner wall of the sliding sleeve 18. The outer wall of the sliding sleeve 18 is provided with an external thread. An adjusting nut 22 is threadedly connected to the external thread of the sliding sleeve 18. A connecting spring 19 is sleeved on the sliding sleeve 18. One end of the connecting spring 19 is connected to the adjusting nut 22. The other end of the connecting spring 19 is connected to the side wall of the fixing plate 16. A fixing frame 20 is provided on the end of the sliding sleeve 18 away from the sliding rod 17. A hob 21 is provided on the fixing frame 20. The hob 21 is rotatably connected to the fixing frame 20 through a rotating shaft 23.

[0051] A plurality of hobbing teeth are evenly arranged on the outer wall of the hob 21 .

[0052] The working principle and beneficial effects of the above technical solution are as follows: the texturing treatment in this application is to use a hob 21 to knurl the outer wall of the battery cell shell to achieve texturing of the outer surface of the battery cell shell, the axis of the hob 21 is perpendicular to the traveling direction of the battery cell 24, and when the battery cell shell passes through the texturing component, the hob 21 contacts the outer wall corresponding to the battery cell shell, such as the hob 21 of the texturing component of the top surface texturing mechanism 6 contacts the upper surface of the battery cell shell, the hob 21 of the texturing component of the edge texturing mechanism 7 contacts the upper edge of the battery cell shell, and the hob 21 of the texturing component of the first side texturing mechanism 8 contacts the front and rear surfaces of the battery cell shell. As the first fixture 5 moves, the battery cell shell passes through the texturing components at different positions in turn, and the outer wall of the hob 21 is evenly distributed with small and hard hobbing teeth, and the hob 2 1. The hardness of the material is greater than that of the battery cell shell. Under the elastic force of the connecting spring 19, the hob 21 can form a tight mesh texture on the outer wall of the battery cell shell, thereby completing the knurling and roughening, which is beneficial to enhancing the adhesion of the paint. Since the hardness of the hob 21 is much greater than the aluminum material of the battery cell shell, the loss of the hob 21 during the roughening process is extremely low, and maintenance-free operation can be achieved during the life cycle of the production line, which is more cost-effective. The pressure applied by the hob 21 on the battery cell shell is determined by the elastic coefficient and compression amount of the connecting spring 19. Turning the adjusting nut 22 can make the sliding rod 17 slide in the sliding sleeve 18, thereby adjusting the distance between the hob 21 and the fixed plate 16, so that the roughening component can adapt to battery cells 24 of different dimensions and ensure processing consistency.
