Description

Technical Field

[0001] The present invention relates to the field of battery processing, and in particular to a square battery insulating film printing system and a printing method. Background Art

[0002] In the traditional square battery production process, the surface of the square battery is usually wrapped with an insulating film using a blue film. During the wrapping process, the blue film is easily scratched by the corners of the battery because the corners of the square battery are more regular and sharp than those of the cylindrical battery. Inadequate wrapping technology may also cause bulges or depressions at the corners. Finally, during the storage and transportation of the battery, the blue film is easily damaged, which will damage the surface insulation ability of the square battery and increase the risks that may arise during the use of the square battery. When using the inkjet printing method to print the insulating film on the square battery, due to the structural characteristics of the square battery, the traditional inkjet printing method is often prone to producing dead corners that cannot be printed, making it difficult to achieve efficient and complete coverage of the square battery surface, and the defect rate is high.

[0052] Example 1

[0053] The present application embodiment discloses a square battery insulation film printing system, such as Figure 1 The specific plan is as follows:

[0054] A square battery insulation film printing system includes: a first working area 1 and a second working area 2 that are independent of each other or connected to each other, wherein the first working area 1 is provided with a first process device 11, and the second working area 2 is provided with a second process device 21. In an optional embodiment, Figure 1 As shown, the system also includes an operating room 91, with a first working area 1 and a second working area 2 located within the operating room 91. The first working area 1 and the second working area 2 can be interconnected or independent of each other. In actual application, the square batteries 92 can be transported between the first working area 1 and the second working area 2 by external equipment or manually.

[0055] The first process equipment 11 and the second process equipment 21 both include a base 3, a conveying mechanism 31 and a battery adjustment device 4; Figure 2 As shown, the first process equipment 11 also includes a texturing treatment component 6; Figure 4 As shown, the second process equipment 21 further includes a cleaning component 7 , a printing component 8 and a curing component 85 .

[0056] The conveying mechanism 31 is arranged on the base 3, and the conveying mechanism 31 includes a starting end 32 and an end end 33. The battery adjustment device 4 is movably arranged on the conveying mechanism 31, and is used to move between the starting end 32 and the end end 33 of the conveying mechanism 31; the texturizing treatment component 6 is arranged on the conveying mechanism 31 of the first process equipment 11; the cleaning component 7, the printing component 8, and the curing component 85 are arranged on the base 3 in sequence along the direction from the starting end 32 to the end end 33 of the conveying mechanism 31 of the second process equipment 21.

[0057] In practical applications, the conveying mechanism 31 includes a conveyor belt and / or a conveyor track. The conveying route of the conveying mechanism 31 can be a straight line or a curve. The user can set the length and conveying route of the conveying mechanism 31 according to actual needs and the distribution location of each component.

[0058] This embodiment separates the texturing process from the cleaning, printing, and curing processes, and sets them in the first process processing equipment and the second process processing equipment respectively, isolating the two different processes. This can prevent the metal dust generated by the laser texturing of the battery surface in the first process from entering the printing area of ​​the second process, causing blockage of the nozzle of the printing mechanism 83 or resulting in film particle defects.

[0059] In actual applications, the two devices can work in parallel. When the first process device 11 is performing the first process on a batch of batteries, the second process device 21 can simultaneously perform the second process on another batch of batteries. This is highly flexible and suitable for mixed-line production. When production demand changes, the production capacity of the two devices can be adjusted separately. When equipment maintenance is required, maintenance can also be performed on the first process device or the second process device separately without stopping the entire production line.

[0060] In some optional embodiments, the battery adjustment device 4 includes a clamping frame, a clamping assembly 42, a control drive mechanism, and a first moving mechanism 43. The clamping frame is movably connected to the conveying mechanism 31 via the first moving mechanism 43. The first moving mechanism 43 is connected to the control drive mechanism and is configured to move along the extension direction of the conveying mechanism 31 under the drive of the control drive mechanism. Specifically, the control drive mechanism is a motor.

[0061] The clamping assembly 42 is mounted on the clamping frame and is used to clamp the prismatic battery 92. The clamping frame is formed with at least one slot 413 for the prismatic battery 92 to pass through. In one embodiment, the contour of the slot 413 matches the largest or second-largest surface of the prismatic battery 92, allowing the prismatic battery 92 to be placed in or against the slot 413 in various configurations.

[0062] In practical applications, the square battery 92 is usually a rectangular parallelepiped structure with six faces, and the six faces can be divided into three groups of faces with different areas, namely the largest area face, the second largest area face, and the smallest area face.

[0063] In some optional embodiments, the clamping frame includes a first plate surface 411, a second plate surface 412, and a support member 414, and the clamping assembly 42 includes a first clamping unit 421, a second clamping unit 422, and a third clamping unit 423. One surface of the second plate surface 412 is connected to the first moving mechanism 43, and the surface facing away from the first moving mechanism 43 is connected to the first plate surface 411 via the support member 414.

[0064] The first plate surface 411 is provided with a first clamping unit 421 and a second clamping unit 422 . The first clamping unit 421 is configured to clamp the largest facing surface of the square battery 92 , and the second clamping unit 422 is configured to clamp the second largest facing surface of the square battery 92 .

[0065] The third clamping unit 423 is disposed on the second plate surface 412 . The third clamping unit 423 is configured to clamp the smallest facing surface of the square battery 92 .

[0066] The first clamping unit 421 includes two pressure plates arranged parallel to the edge of the card slot 413, and the pressure plates are used to abut against the edge of the opposite surface with the largest area; by setting the pressure plates to abut against the edge of the opposite surface with the largest area of ​​the square battery 92, the square battery 92 can be stably clamped, and the largest surface of the square battery 92 is directed toward the various components undergoing process processing in the first process equipment 11 or the second process equipment 21, so as to facilitate the first process or the second process processing.

[0067] The second clamping unit 422 includes at least two elastic clamping arms, which are used to abut against the edge of the secondary large area opposite surface; by setting the elastic clamping arms, it can flexibly cooperate to clamp square batteries 92 of different models, lengths and widths, so that one of the secondary large area opposite surfaces of the square battery 92 can face the various components undergoing process processing in the first process equipment 11 or the second process equipment 21, thereby facilitating the first process or second process processing.

[0068] The third clamping unit 423 includes at least one positioning card block, the shape of which is adapted to the outer contour of the minimum area relative surface of the square battery 92. In a specific embodiment, the square battery 92 is a rectangular parallelepiped structure. When processing the minimum area relative surfaces of the square battery 92, the square battery 92 needs to be placed in a clamping frame with one of the minimum area surfaces as the bottom and the other minimum area surface as the top. Based on the rectangular parallelepiped structural characteristics of the square battery 92, at this time, the square battery 92 can be located with its bottom on the second plate surface 412 and clamped by the positioning card block in the third clamping unit 423, and the top of the square battery 92 can be exposed relative to the first plate surface 411 through the card slot 413, so that the minimum area surface at the top of the square battery 92 can enter the first process processing or the second process processing.

[0069] The user can flexibly use different clamping units to clamp different positions of the square battery 92 to expose different areas of the surface of the square battery 92 so as to process different areas of the surface of the square battery 92 .

[0070] In some optional embodiments, the printing system also includes a second moving mechanism 44 and a moving track 45; the moving track 45 is arranged on the first moving mechanism 43, and the extension direction of the moving track 45 is perpendicular to the extension direction of the conveying mechanism 31; the clamping assembly 42 is movably connected to the moving track 45 through the second moving mechanism 44, and the second moving mechanism 44 is used to drive the clamping assembly 42 to move along the moving track 45.

[0071] In actual application, by setting a movable track 45 on the first movable mechanism 43, the relative position adjustment between the second movable mechanism 44 and the first movable mechanism 43 can be achieved, so that the horizontal movement of the battery has two dimensions. During the printing process, the second movable mechanism 44 can achieve more precise displacement based on specific needs on the basis of the first movable mechanism 43.

[0072] In some optional embodiments, the texturing assembly 6 and / or the cleaning assembly 7 includes a support frame 51 and a visual inspection module 5. The support frame 51 is disposed on the base 3; the visual inspection module 5 is disposed on the support frame 51 on a side facing the starting end 32 of the conveying mechanism 31.

[0073] The visual detection module 5 includes a visual sensor 52 and a positioning frame 53. The positioning frame 53 is fixedly connected to the support frame 51, and the visual sensor 52 is movably connected to the area on the support frame 51 corresponding to the area above the positioning frame 53; a light source assembly 54 is provided on the surface of the positioning frame 53 facing the conveying mechanism 31, and the light source assembly 54 is used to illuminate the area of ​​the positioning frame 53 corresponding to the conveying mechanism 31.

[0074] In an optional embodiment, the visual detection module 5 also includes a fourth moving mechanism 55, and the visual sensor 52 is movably connected to the support frame 51 through the fourth moving mechanism 55. In actual application, the fourth moving mechanism 55 and the visual sensor 52 in the visual detection module 5 can be communicated with the external host computer 93, and the visual sensor 52 sends the captured visual data to the external host computer 93, and the visual data is detected by the external host computer 93. When it is detected that the position of the battery deviates from the preset printing area, an instruction can be sent to the first moving mechanism 43 and / or the second moving mechanism 44 to move the first moving mechanism 43 and / or the second moving mechanism 44 to further adjust the position of the battery to meet the requirements of the preset printing area.

[0075] In actual applications, the visual sensor 52 includes a camera, the shooting area of ​​the camera covers the area where the positioning frame 53 is located, and the light source assembly 54 includes a lamp bead component arranged on the positioning frame 53, which can illuminate the square battery 92 in the positioning frame 53 in the vertical direction, thereby improving the clarity of the camera's shooting of the battery surface and facilitating the detection of defects on the battery surface.

[0076] By setting a camera to photograph the square battery 92 before the battery undergoes laser roughening or printing, the edge contour, positioning holes, tabs and other features of the battery can be captured, and the clamping position of the battery can be calibrated to avoid the error between the clamping position of the battery and the roughening processing component or the printing component 8, which may cause the roughening or printing effect to be offset.

[0077] For features such as the tabs, welding areas, and logos on the battery surface, a local coordinate system can be established through visual recognition, allowing the printed pattern in the laser roughening area to be precisely aligned with the battery's functional area. Furthermore, by setting up a visual sensor 52, defects on the battery surface can be identified, and scratches, indentations, oxidation spots, etc. on the battery surface can be detected. Batteries can be screened and abnormal batteries can be identified in a timely manner to avoid further anomalies that may occur in subsequent work. At the same time, the visual sensor 52 can also measure the length, width, and height of the battery, which can avoid inconsistent roughening depth or incomplete printing of the insulating film due to the battery size exceeding the preset value.

[0078] In this embodiment, by separating the first process and the second process and using the visual inspection module 5, at least one visual inspection process can be added between the first process and the second process. After the battery completes the roughening operation, it can be inspected by the visual inspection module 5 in the first process equipment 11 again. When the battery enters the second process equipment 21, it can also undergo another visual inspection in the visual inspection module 5 of the second process. Through repeated inspections, the defect rate of finished products can be effectively reduced.

[0079] In some optional embodiments, such as Figure 3 As shown, the texturing component 6 also includes a laser module 61 and a dust treatment module 62. The laser module 61 is arranged on the support frame 51 on the side of the terminal end 33 of the conveying mechanism 31. The dust treatment module 62 includes a dust recovery pipe 621 and a purge pipe 623; one end of the purge pipe 623 is movably connected to the laser module 61 or the support frame 51, and the other end is provided with a blowing port 624; the blowing port 624 of the purge pipe 623 is arranged toward the recovery port 622 of the dust recovery pipe 621. In actual application, the purge pipe 623 is a retractable pipe. When the user needs to perform dust purging, the purge pipe 623 can be extended and moved in a direction close to the square battery 92 to treat the dust on the surface of the square battery 92.

[0080] In actual application, the laser module 61 includes a laser. During the laser texturing process of the battery surface, a high-energy-density laser beam is focused on the battery surface. By laser texturing the battery surface, the surface roughness of the square battery 92 can be increased, so that in the subsequent process of printing the insulating layer on the battery surface, the printed insulating layer has stronger adhesion to the surface of the square battery 92. During the laser texturing process, the metal substrate, polymer materials, etc. on the surface of the square battery 92 are affected, and metal dust, debris, etc. may be generated. By providing a purge pipe 623 and a dust recovery pipe 621 near the laser module 61, the dust on the surface of the square battery 92 can be blown up by the purge pipe 623, and then the dust recovery pipe 621 generates a negative pressure to suck the dust on the surface of the square battery 92, forming a push-suction closed loop, thereby keeping the surface of the square battery 92 clean after laser texturing.

[0081] In some optional embodiments, the cleaning assembly 7 includes a plasma spray gun 72 and a dust isolation hood 71. The conveying mechanism 31 passes through the dust isolation hood 71, and one end of the plasma spray gun 72 enters the dust isolation hood 71 and corresponds to the conveying mechanism in the dust isolation hood 71. In actual application, when the plasma spray gun 72 is used to clean the surface of the square battery 92, debris and dust that may remain on the surface of the square battery 92 after texturization can be further cleaned. During this process, the dust isolation hood 71 can prevent debris and dust from splashing outward.

[0082] In some optional embodiments, the specific structure of the printing component 8 is as follows Figure 5 As shown, the printing assembly 8 includes a fixed bracket 81, a third movable mechanism 82, a printing mechanism 83 and a liquid receiving box 84. The fixed bracket 81 is arranged on the base 3, and the printing mechanism 83 is connected to the fixed bracket 81 via the third movable mechanism 82 in a liftable manner.

[0083] One end of the liquid receiving box 84 is rotatably connected to the fixed bracket 81. The liquid receiving box 84 is configured to rotate horizontally relative to the fixed bracket 81 to correspond to or move away from the nozzle of the printing mechanism 83. By providing the liquid receiving box 84, it is possible to accommodate paint dripping from the nozzle of the printing mechanism 83, preventing the paint from contaminating other components. In actual applications, a discharge pipe for discharging paint can be further provided at the bottom of the liquid receiving box 84 to promptly discharge the liquid in the liquid receiving box 84 to an external recovery system. By rotating the liquid receiving box 84 horizontally relative to the fixed bracket 81, the liquid receiving box 84 will not block the printing mechanism 83 when the printing mechanism 83 is performing printing operations.

[0084] In some optional embodiments, the specific structure of the curing component 85 is as follows: Figure 6 As shown, the curing assembly 85 includes a light shield 86 and a curing light source 88 disposed within the light shield 86. The light shield 86 is provided with at least one entrance through which one end of the conveying mechanism enters the light shield 86; a liftable light shield 87 is provided at the entrance of the light shield 86. In actual applications, the curing light source 88 is a UV lamp. By providing the light shield 86 and the liftable light shield 87, a relatively enclosed space can be formed for performing the curing operation.

The printing component 8 performs a printing operation on one of the surfaces to be printed on the square battery 92.

[0106] S233. After the printing operation is completed, the battery adjustment device 4 clamps the square battery 92 and moves from the printing component 8 to the curing component 85. The curing component 85 performs a curing operation on one of the surfaces to be printed of the square battery 92.

In view of the structural characteristics of the square battery, the surface of the square battery can be processed by the first process and the second process respectively on a surface basis, which can effectively improve the adhesion of the insulating film printed on the surface of the square battery. By separating the surface texturing operation of the battery from the cleaning, printing, and curing operations, the visual inspection module can be further used to perform multiple inspections on the square battery, which can effectively reduce the defect rate of the finished square battery and improve the printing efficiency.
