Description

Technical Field

[0001] The present invention relates to the technical field of battery production equipment, and in particular to an automatic roller-changing film coating mechanism and method. Background Art

[0002] At present, battery coating refers to the outer film or shell used to wrap the battery to protect the internal structure of the battery and prevent battery short circuit, leakage and other problems. During the battery production process, due to possible manufacturing errors or design differences in the battery itself, its surface and sides often have different degrees of unevenness, which leads to poor surface consistency when the battery is coated.

[0003] However, when processing such batteries, traditional coating machines only use a single set of pressure rollers to coat the batteries. If the incoming battery material has a large degree of unevenness and the fit with each roller is poor, blue film bubbles and wrinkles will appear on the side of the battery, requiring manual film tearing and classification. When switching to other rubber rollers with different convexities, the traditional coating machine can only be shut down for intervention, which not only has a low yield but also is difficult to debug, time-consuming and labor-intensive, resulting in unsatisfactory coating efficiency and may even damage the battery.

[0023] In order to solve the problem that the coating machine in the prior art is difficult to adapt to batteries with greater unevenness, resulting in low coating efficiency, the present invention provides an automatic roller-changing coating mechanism and method.

[0024] Please refer to Figure 1 and Figure 3As shown, an aspect of the technical solution of the present invention is applied, providing an automatic roller-changing coating mechanism, comprising a detection device 10 and a coating device 20; the detection device 10 comprises a frame body 11 and a detection component 12 movably arranged on the frame body 11, and a conveying component 13 for placing the battery 1 is provided on the frame body 11, so that the detection component 12 detects the degree of concavity and convexity of the surface of the battery 1 located on the conveying component 13; the coating device 20 is arranged at the downstream of the detection device 10 along a preset process direction, and the coating device 20 comprises a coating structure 30, and the coating structure 30 comprises a base body 31 and a first pressing roller assembly 32 and a second pressing roller assembly 33 movably arranged on the base body 31, so that according to the degree of concavity and convexity of the surface of the battery 1 detected by the detection component 12, the first pressing roller assembly 32 and the second pressing roller assembly 33 can be selectively controlled to coat the battery 1.

[0025] By applying the technical solution of this embodiment, the battery 1 enters the coating area through the conveying component 13, and the detection component 12 performs real-time detection of the surface unevenness of the battery 1 located on the conveying component 13, and then the control system analyzes the shape of the battery 1 according to the detection data sent back by the detection component 12, and determines whether the roller needs to be replaced, that is, the first pressing roller assembly 32 or the second pressing roller assembly 33 matching the surface shape of the battery 1 is selected to coat the battery 1, so as to ensure that the coating process of the battery 1 proceeds smoothly, and then adapt to batteries 1 with different degrees of unevenness, so as to solve the problem that the coating machine in the prior art is difficult to adapt to batteries 1 with larger degrees of unevenness, resulting in low coating efficiency, thereby improving the coating effect and production efficiency, while reducing the damage and rework rate of the battery 1 caused by poor coating, and reducing production materials and labor costs.

[0026] In this embodiment, the detection component 12 is a high-precision displacement sensor.

[0027] In this embodiment, specifically, there are two coating structures 30, and the coating device 20 further includes a support frame 40 and a clamping assembly 50; the two coating structures 30 are respectively arranged on opposite sides of the support frame 40; the clamping assembly 50 is movably arranged on the support frame 40, and the clamping assembly 50 includes a clamping claw component 51 that can move in the vertical direction, so that the clamping claw component 51 clamps the battery 1 and drives the battery 1 to move to a position corresponding to the first pressing roller component 32 or the second pressing roller component 33. In this way, after the unevenness of the surface of the battery 1 is detected, the battery 1 is clamped by the clamping claw component 51 and the battery 1 is driven to rise in the vertical direction to a position corresponding to the first pressing roller component 32 and the second pressing roller component 33 of the coating structure 30, and then the corresponding first pressing roller component 32 or the second pressing roller component 33 on the two coating structures 30 is selected according to the detection result of the detection component 12 to respectively perform coating operation on the surface of the battery 1.

[0028] like Figure 1As shown, the film coating structure 30 further includes a push assembly 34, which is movably arranged on the base body 31 in the direction toward the clamping assembly 50, and the first pressing roller assembly 32 and the second pressing roller assembly 33 are movably arranged on the push assembly 34 in the vertical direction, respectively, so as to drive the first pressing roller assembly 32 and the second pressing roller assembly 33 to selectively move to a position in contact with the surface of the battery 1. In this way, after the unevenness of the surface of the battery 1 is detected and the corresponding pressing roller is selected for film coating according to the detection result, the first pressing roller assembly 32 or the second pressing roller assembly 33 is pushed to a position close to the supporting frame 40 by the push assembly 34, and then the first pressing roller assembly 32 or the second pressing roller assembly 33 is controlled to move in the vertical direction to contact with the surface of the battery 1 for the convenience of subsequent film coating operation.

[0029] Specifically, the first mounting plate 35 and the second mounting plate 36 are provided on one end of the push assembly 34 facing the clamping assembly 50 from top to bottom and relatively movable, and the first pressing roller assembly 32 includes a first pressing roller component 320 and a second pressing roller component 321, and the first pressing roller component 320 and the second pressing roller component 321 are respectively arranged on the first mounting plate 35 and the second mounting plate 36, so that the first pressing roller component 320 and the second pressing roller component 321 coat the side of the battery 1. In this way, after the detection component 12 detects that the concave-convex degree of the surface of the battery 1 exceeds the preset value, the second pressing roller assembly 33 is selected to be replaced, and after the push assembly 34 pushes the first pressing roller component 320 and the second pressing roller component 321 to the upper and lower sides close to one side of the battery 1, the first mounting plate 35 and the second mounting plate 36 are controlled to drive the first pressing roller component 320 and the second pressing roller component 321 to move relative to each other, so that the first pressing roller component 320 moves downward and the second pressing roller component 321 moves upward, so that the blue film is respectively attached to the upper and lower sides of the battery 1.

[0030] Specifically, the second roller assembly 33 is arranged on the first mounting plate 35, and the second roller assembly 33 includes a guide rail seat 330 and a third roller component 331; the guide rail seat 330 is arranged on the first mounting plate 35 and is located above the first roller component 320; at least part of the third roller component 331 is slidably connected to the guide rail seat 330, so that the third roller component 331 coats the top surface of the battery 1 in the direction toward the battery 1. In the above arrangement, the guide rail seat 330 is a servo electric cylinder slide rail. In this way, after the detection component 12 detects that the concave-convex degree of the surface of the battery 1 does not exceed the preset value, there is no need to replace the roller, and after the pushing component 34 pushes the third roller component 331 to the top close to the top surface of the battery 1, the third roller component 331 is controlled to slide on the guide rail seat 330 to make the blue film close to the top surface of the battery 1.

[0031] like Figure 1As shown, the push assembly 34 includes a push frame 340, a first slider 341 is provided on the bottom of the push frame 340, a first guide rail 310 is provided on the base body 31, and the first slider 341 is slidably connected to the first guide rail 310; two second guide rails 342 are provided in the vertical direction on one end of the push frame 340 facing the battery 1, and the first mounting plate 35 and the second mounting plate 36 are respectively slidably connected to the two second guide rails 342. In the above configuration, a driving cylinder is connected to the push frame 340, so that the first slider 341 on the push frame 340 is driven by the driving cylinder to move along the extension direction of the first guide rail 310 to drive the first roller assembly 32 and the second roller assembly 33 to move to a position close to the battery 1, and the first mounting plate 35 and the second mounting plate 36 are respectively controlled to move along the extension direction of the first guide rail 310 to drive the first roller assembly 32 or the second roller assembly 33 to coat the battery 1.

[0032] Specifically, the clamping assembly 50 includes two placement brackets 52 and a driving component 53; the two placement brackets 52 are arranged opposite to each other and a mounting groove 520 is provided on the top of the placement bracket 52, and the battery 1 is mounted in the two mounting grooves 520; the driving component 53 is respectively connected to the two placement brackets 52 and is located between the two placement brackets 52, and the clamping claw component 51 is drivingly connected to the driving end of the driving component 53 to drive the clamping claw component 51 to move toward the battery 1 in the vertical direction. In the above arrangement, the driving component 53 is a driving motor, so that after the battery 1 is transported to the two placement brackets 52 and located in the two mounting grooves 520, the driving component 53 drives the clamping claw component 51 to move upward in the vertical direction and clamp the battery 1 placed in the two mounting grooves 520 to position the battery 1, so as to facilitate the subsequent selection of the first pressing roller assembly 32 or the second pressing roller assembly 33 to perform a film coating operation on the battery 1.

[0033] In this embodiment, the clamping jaw component 51 includes a fixing seat 510 and two clamping plates 511; the fixing seat 510 is connected to the driving end of the driving member 53; the two clamping plates 511 are relatively movably arranged on the fixing seat 510, so that after the driving member 53 drives the two clamping plates 511 to move to a position in contact with the battery 1, the two clamping plates 511 move relatively close to each other to clamp the battery 1. In this way, after the battery 1 is placed in the mounting groove 520 on the placement bracket 52, the two clamping plates 511 of the clamping jaw component 51 are controlled to move relatively away from each other to open and the two clamping plates 511 are controlled to move to both sides of the battery 1, and then the two clamping plates 511 are controlled to move relatively close to each other to clamp and position the battery 1, thereby driving the battery 1 to move to a position corresponding to the first pressing roller assembly 32 and the second pressing roller assembly 33.

[0034] In this embodiment, two third guide rails 41 are respectively provided on the support frame 40, and the bottoms of the two placement brackets 52 are respectively slidably connected to the two third guide rails 41. A placement platform 42 is provided on the support frame 40 above the two third guide rails 41, and at least part of the placement platform 42 is located between the two placement brackets 52 and below the driving component 53, so as to place the battery 1. In this way, the placement bracket 52 moves along the extension direction of the third guide rails 41 to receive and transport the battery 1, and the battery 1 located on the placement platform 42 is moved to the installation groove 520 on the placement bracket 52 by the manipulator, and the battery 1 is positioned in combination with the clamping claw component 51, so as to facilitate the subsequent stable film coating of the battery 1 by the first roller assembly 32 or the second roller assembly 33.

[0035] like Figure 3 As shown, there are two conveying components 13, and the two conveying components 13 are respectively arranged on opposite sides of the frame body 11. The detection device 10 also includes a moving component 14; the moving component 14 is arranged on the frame body 11, and the moving component 14 includes a fixed module 140 and a moving block 141 movably arranged on the fixed module 140. The detection component 12 is arranged on the moving block 141, so that the moving block 141 drives the detection component 12 to move between the two conveying components 13, so as to detect the concave-convex degree of the surface of the battery 1 located on any conveying component 13. In the above arrangement, the moving block 141 is movably connected to the fixed module 140 through an electric cylinder. In this way, the battery 1 is transported to any conveying component 13 by the manipulator, and after the battery 1 is transported to the preset positioning point by any conveying component 13, the positioning sensor sends a signal to the control system, and the control system controls the electric cylinder to drive the moving block 141 to move along the extension direction of the fixed module 140 to the position corresponding to the battery 1, and then uses the detection component 12 which is a high-precision displacement sensor to detect the thickness change of the surface of the battery 1 (the measurement range is 0-50mm, and the repeatability accuracy is above 0.1um), that is, the degree of concave-convexity, and then feeds back to the programmable control system through the change of analog value, so as to achieve rapid response and precise adjustment, and judge whether to use the first pressing roller assembly 32 or the second pressing roller assembly 33 for subsequent coating action according to the detection result, thereby reducing manual intervention, improving production efficiency and coating quality, and being compatible with batteries 1 of various shapes and sizes to meet different production needs.

[0036] Another aspect of the technical solution of the present invention provides an automatic roller-changing coating method, which is applicable to the automatic roller-changing coating mechanism mentioned above, including controlling the detection component 12 of the detection device 10 to detect the concave-convex degree of the battery 1 surface; obtaining the detection result of the detection component 12, and judging whether to replace the first pressing roller assembly 32 or the second pressing roller assembly 33 according to the detection result, so as to control the first pressing roller assembly 32 or the second pressing roller assembly 33 to coat the top surface, the bottom surface and the two opposite sides of the battery 1 respectively. In this way, the concave-convex degree of the battery 1 surface can be detected in real time by the detection device 10, and the appropriate first pressing roller assembly 32 or the second pressing roller assembly 33 can be automatically selected according to the actual shape characteristics of the battery 1, avoiding the problem that the traditional coating machine is difficult to adapt to batteries 1 with different concave-convex degrees due to the fixed pressing roller, and can effectively reduce the undesirable phenomena such as bubbles and wrinkles in the coating process, thereby improving the coating quality, reducing the battery damage rate caused by poor coating, and significantly improving the adaptability and overall efficiency of the coating process.

[0037] In this embodiment, the step of judging whether to replace the first roller assembly 32 or the second roller assembly 33 according to the detection result includes: when the detection result is less than a preset value, there is no need to replace the second roller assembly 33, and the third roller components 331 of the second roller assemblies 33 of the two coating structures 30 are controlled to coat the battery 1 respectively; and / or, when the detection result is greater than or equal to the preset value, the second roller assembly 33 is replaced with the first roller assembly 32, so as to control the first roller components 320 and the second roller components 321 of the first roller assemblies 32 of the two coating structures 30 after replacement to coat the battery 1 respectively. In this way, by real-time detection of the concave-convex degree of the battery 1 surface, the system can automatically judge whether the battery 1 is suitable for coating using the current roller assembly. When the surface unevenness of the battery 1 does not exceed the preset value, the third roller component 331 of the second roller assembly 33 is used to coat the top surface, bottom surface and two opposite side surfaces of the battery 1 in turn, without replacing the roller assembly, thereby ensuring the continuity and efficiency of the coating process; and when the surface unevenness of the battery 1 exceeds the preset value, the first roller assembly 32 is replaced and selected, and the first roller component 320 and the second roller component 321 are used to coat the top surface, bottom surface and two opposite side surfaces of the battery 1 in turn, thereby ensuring that all batteries 1 can receive appropriate coating treatment, avoiding battery damage and rework due to improper coating, and significantly improving the coating quality and production efficiency.

In this way, the battery 1 enters the coating area through the conveying component 13, and the detection component 12 performs real-time detection of the surface unevenness of the battery 1 located on the conveying component 13, and then the control system analyzes the shape of the battery 1 according to the detection data sent back by the detection component 12, and determines whether the roller needs to be replaced, that is, the first pressing roller assembly 32 or the second pressing roller assembly 33 matching the surface shape of the battery 1 is selected to coat the battery 1, so as to ensure that the coating process of the battery 1 proceeds smoothly, and then adapt to batteries 1 with different degrees of unevenness, so as to solve the problem that the coating machine in the prior art is difficult to adapt to batteries 1 with larger degrees of unevenness, resulting in low coating efficiency, thereby improving the coating effect and production efficiency, while reducing the damage and rework rate of the battery 1 caused by poor coating, and reducing production materials and labor costs.
