Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically to a coating testing mechanism. Background Technology

[0002] Semi-dry lithium batteries typically use a composite material consisting of polymers, inorganic solids, and liquid electrolytes. This electrolyte combines the high mechanical strength of solid electrolytes with the high ionic conductivity of liquid electrolytes. In semi-dry lithium batteries, the electrolyte typically contains between 5% and 10% water, hence the term "semi-dry."

[0003] However, there are some problems with double-sided coating. Since adhesive needs to be applied to both sides of the electrode, if the electrode is supported by a roller, the adhesive on the electrode will contaminate the roller surface. In addition, there is a lack of detection methods for the electrode, so it is impossible to determine whether there are defects in the electrode.

[0004] Therefore, there is a need to provide an adhesive coating testing agency to solve the above problems. Utility Model Content

[0028] Reference Figure 1 , Figure 2 A coating inspection mechanism includes a first roller frame 1 and a second roller frame 2. The first roller frame 1 includes a guide roller 11, a first air-float roller 12, and coating components 4. The guide roller 11 is located at the lower part of the first roller frame 1, and the first air-float roller 12 is located at the upper end of the first roller frame 1. The two coating components 4 are respectively located on opposite positions of the guide roller 11 and the first air-float roller 12. The coating components 4 are used to coat the passing electrode sheet 6 with adhesive. The two coating components 4 are located on both sides of the electrode sheet 6 to perform double-sided coating. The use of the air-float roller allows the electrode sheet 6 to float 1-2 mm away from the roller surface, reducing friction of the electrode sheet 6 during transmission, avoiding damage to the adhesive layer, and ensuring stable transmission of the electrode sheet 6, thus providing conditions for high-quality coating and inspection.

[0029] The second roller frame 2 is located at the rear end of the first roller frame 1. The second roller frame 2 includes a second air-bearing roller 21, a third air-bearing roller 22, and two CCD components 5. The second air-bearing roller 21 and the third air-bearing roller 22 are respectively located on the upper and lower sides of the second roller frame 2. Both the second air-bearing roller 21 and the third air-bearing roller 22 are equipped with the CCD components 5, and the two CCD components 5 are respectively located on both sides of the electrode sheet 6's travel path. The CCD components 5 are used to perform defect detection on both sides of the coated electrode sheet 6. This enables simultaneous defect detection on both sides of the coated electrode sheet 6, improving the comprehensiveness and accuracy of electrode sheet inspection.

[0030] Reference Figure 2 In the embodiments of this utility model, the first roller frame 1 and the second roller frame 2 each include a column 7 and a mounting plate 8 to support the through roller and the air-bearing roller. The two ends of the through roller 11 are respectively fixedly connected to the column 7. The first air-bearing roller 12, the second air-bearing roller 21 and the third air-bearing roller 22 are respectively fixedly installed to the column 7 through the mounting plate 8, so that each roller frame can be installed and disassembled independently, which facilitates the maintenance, upgrading and expansion of the equipment.

[0031] The first air-bearing roller 12 and the second air-bearing roller 21 are on the same horizontal line, and the electrode 6 is horizontally tangent to the first air-bearing roller 12 and the second air-bearing roller 21 respectively, ensuring the horizontal conveying of the electrode 6 on the first air-bearing roller 12 and the second air-bearing roller 21. The second air-bearing roller 21 and the third air-bearing roller 22 are respectively arranged on both sides of the electrode 6, so that the electrode 6 is vertically tangent to the second air-bearing roller 21 and the third air-bearing roller 22 respectively, and is vertically conveyed. At the same time, it also effectively changes the conveying direction of the rear end of the electrode 6, so as to ensure the stability and smoothness of the electrode 6 during the transmission process.

[0032] A third roller frame 3 is provided at the rear end of the second roller frame 2. The third roller frame 3 includes a fourth air-bearing roller 31 and a column 7. The fourth air-bearing roller 31 is fixed on the column 7. The fourth air-bearing roller 31 and the third air-bearing roller 22 are on the same horizontal line, so that the electrode 6 is horizontally tangent to the third air-bearing roller 22 and the fourth air-bearing roller 31 respectively, and is horizontally conveyed. By adding the third roller frame 3, the glue coating and inspection mechanism forms a multi-stage processing flow: glue coating → inspection → subsequent processing, making the entire production process more complete and efficient.

[0033] The coating assembly 4 includes a coating head 41, which is spaced apart from the electrode 6. By precisely controlling the contact point between the coating head 41 and the electrode 6, the amount of adhesive can be finely adjusted, ensuring the uniformity and accuracy of the adhesive coating, thereby improving the coating quality.

The mounting base 45 is provided on the outer side of the longitudinal sliding assembly 44, and both ends of the longitudinal sliding assembly 44 are fixedly connected to the mounting base 45. The longitudinal sliding assembly 44 provides the coating assembly 4 with the ability to adjust its longitudinal position. The coating assembly 4 can be stably installed on other support devices or completely removed through the mounting base 45, which is convenient for maintenance and replacement.

[0035] Specifically, the dispensing valve assembly 42 includes a dispensing valve 421, a fixed bracket 422, a slider 423, and an adapter plate 424. The coating head 41 is installed at the front end of the dispensing valve 421. The dispensing valve 421 can extract the coating fluid material from the storage container and then accurately coat it onto the surface of the electrode 6 through the coating head 41. The dispensing valve 421 is fixed on the fixed bracket 422 to ensure the stability and accuracy of the dispensing valve 421 during operation. The fixed bracket 422 is fixed on the slider 423 through the adapter plate 424. The slider 423 is slidably connected to the transverse sliding assembly 43, thereby allowing the dispensing valve assembly 42 to move laterally left and right, and to be more accurately positioned at the desired coating position.

[0036] Specifically, the transverse sliding assembly 43 includes a guide rail base 431, a linear guide rail 432, a fixing member 433, and an embossed knob 434. The guide rail base 431 provides a platform for mounting the linear guide rail 432 and connecting the longitudinal sliding assembly 44. Both ends of the guide rail base 431 are connected to the longitudinal sliding assembly 44. The linear guide rail 432 is fixed on the guide rail base 431, allowing the entire transverse sliding assembly 43 to move longitudinally back and forth. The slider 423 is slidably connected to the linear guide rail 432, which provides a precise sliding track for the slider 423. This allows the dispensing valve assembly 42 to be adjusted horizontally. The fixing member 433 is located at one end of the slider 423, and the embossed knob 434 passes through the fixing member 433 and abuts against the linear guide rail 432. The embossed knob 434, together with the fixing member 433, plays a role in fixing and locking, locking the dispensing valve assembly 42 after it moves to the designated position. Furthermore, anti-collision blocks 435 are also provided at intervals in the middle of the guide rail seat 431 to prevent the slider 423 from exceeding the predetermined range during movement, thereby avoiding collisions with the guide rail seat 431 or other components.

[0037] Specifically, the longitudinal sliding assembly 44 includes a pneumatic slide table 441, a hydraulic damper 442, a damper bracket 443, and a sliding plate 444. The pneumatic slide table 441 is fixed to one end of the mounting base 45, providing a stable support and driving platform for the longitudinal sliding assembly 44. The piston rod of the hydraulic damper 442 is slidably connected to the pneumatic slide table 441. One end of the sliding plate 444 is fixed to the hydraulic damper 442, and the other end of the sliding plate 444 is slidably connected to the pneumatic slide table 441. The guide rail seat 431 is fixedly connected to the sliding plate 444, and the pneumatic... The slide table 441 drives the sliding plate 444 and the dispensing valve assembly 42 to move longitudinally back and forth along the pneumatic slide table 441, thereby realizing the adjustment of the longitudinal back and forth position of the dispensing valve assembly 42. The hydraulic damper 442 is mainly used to absorb and reduce the impact and vibration of the pneumatic slide table 441 during movement. The fixed end of the hydraulic damper 442 is fixed to the other end of the mounting base 45 through the damper bracket 443. The damper bracket 443 is used to firmly install the hydraulic damper 442 on the mounting base 45, ensuring the stability and reliability of the hydraulic damper 442, thereby ensuring the performance of the entire longitudinal sliding assembly 44.

[0038] The CCD assembly 5 includes a CCD lens 51 and a supplementary light 52. The two ends of the CCD lens 51 are respectively connected to the ends of the second air float roller 21 or the third air float roller 22, thereby realizing comprehensive defect detection of the electrode sheet 6. The supplementary light 52 is set on one side of the CCD lens 51. The supplementary light 52 enhances the illumination effect of the CCD lens 51 on the surface of the electrode sheet 6, and improves the accuracy and sensitivity of defect detection.

[0039] During use, the electrode 6 first passes through the roller 11 of the first roller frame 1, where the first coating component 2 applies adhesive to one side. It then passes through the first air-float roller 12, where the second coating component 2 applies adhesive to both sides, ensuring both sides of the electrode 6 are coated. After coating, the electrode passes through the first CCD component 5 of the second roller frame 2 for one-side inspection, followed by the second CCD component 5 for the second-side inspection, checking for defects. This invention's adhesive coating inspection mechanism, through the air-float roller and double-sided adhesive coating design, achieves double-sided adhesive coating of the electrode and uses CCD components to perform quality inspection on the coated electrode, improving the uniformity of the adhesive coating and the quality of the electrode.
