Description

Technical Field

[0001] This utility model relates to the field of composite diaphragm processing, and in particular to a composite diaphragm coating device with a dust cover. Background Technology

[0002] Composite separator coating is a technique that coats one or more layers of coating onto the surface of a separator, aiming to give the separator additional functions or performance. This technique is widely used in lithium batteries and other applications that require high-performance separators. The performance of the separator determines the battery's interface structure, internal resistance, etc., and directly affects the battery's capacity, cycle life, and safety performance.

[0003] The prior art utility model patent with publication number CN 205868681 U discloses a diaphragm coating device with a dust cover. The dust cover extends from the upper part of the drying mechanism to the upper part of the coating mechanism. The dust cover is added to cover the diaphragm during the diaphragm coating process, which effectively prevents dust and debris in the air from affecting the coating quality of the diaphragm, thereby reducing the scrap rate and further improving the safety performance of the battery.

[0004] However, its dust cover has a simple structure, is directly installed on the upper part of the working area, and has only one set of flip-up second cover plates. The internal space is small, which makes it inconvenient for inspection, maintenance and loading / unloading operations. The visibility of the cover plate is also poor, which makes it difficult for workers to observe during operation and diagnose later faults. As a result, the equipment is not very practical. Therefore, we need to upgrade and modify it based on the existing technology to overcome the existing problems and shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a composite diaphragm coating device with a dust cover to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 As shown in Figure 4, this embodiment provides a composite diaphragm coating device with a dust cover, including a device body 1. The device body 1 includes a coating machine 2, a protective component 3, and an adjusting component 6. The front end of the coating machine 2 is provided with a feeding roller 4 and a guide roller 5 is provided on one side of the feeding roller 4. The adjusting component 6 is provided on one side of the upper end of the guide roller 5. The protective component 3 is provided at the front end of the coating machine 2 and is respectively sleeved on the outside of the feeding roller 4, the guide roller 5, and the adjusting component 6.

[0025] Preferably, the protective component 3 includes an outer frame 31 and a glass door 35. The upper end and both sides of the outer frame 31 are provided with glass covers 32. The front end of the outer frame 31 is provided with two sets of front openings 33. The glass door 35 is symmetrically provided with two sets and is respectively located in the front openings 33 on both sides. The side of the front opening 33 is provided with a hinge sleeve 34. The side of the glass door 35 is fixed with a plug shaft 36. The plug shaft 36 is rotatably inserted into the hinge sleeve 34. The outside of the glass door 35 is provided with a handle. A fixing bolt 39 is installed between the hinge sleeve 34 and the outer frame 31. The side of the front opening 33 is provided with an inner magnetic strip 37. The inside of the glass door 35 is provided with an outer magnetic strip 38 and the outer magnetic strip 38 corresponds to the inner magnetic strip 37.

[0026] The outer frame 31 and glass cover 32 are fitted onto the front end of the coating machine 2. The glass door 35 can be rotatably connected to the outside of the front opening 33 through the cooperation of the plug shaft 36 and the hinge sleeve 34. The glass door 35 is magnetically limited by the inner magnetic strip 37 and the outer magnetic strip 38, thereby achieving the protective effect of covering the working area of ​​the coating machine 2. This facilitates the protection of the composite diaphragm and equipment from dust and dirt. The loading, unloading and maintenance of the diaphragm are convenient, and there is no need to disassemble the protective component 3 as a whole, which effectively improves the practicality of the device.

[0027] Preferably, the adjustment assembly 6 includes a mounting frame 61, with guide grooves 62 on both sides of the mounting frame 61. A threaded rod 63 is threaded through the middle of the mounting frame 61, and a movable frame 64 is rotatably connected to the threaded rod 63. An adjustment roller 67 is provided at the upper end of the movable frame 64. Guide sliders 68 are provided at both ends of the adjustment roller 67, and the guide sliders 68 slide within the guide grooves 62. The mounting frame 61 is fixed to the front end of the coating machine 2 and has guide holes 65 on both sides. Two sets of guide rods 66 are provided at the lower end of the movable frame 64, and the guide rods 66 move through the guide holes 65.

[0028] The threaded rod 63 drives the moving frame 64 and the guide rod 66 to move along the direction of the guide hole 65. The moving frame 64 drives the adjusting roller 67 and the guide slider 68 to move along the direction of the guide groove 62, thereby enabling the height adjustment operation of the adjusting roller 67. This facilitates changing the tension of the adjusting roller 67 on the composite diaphragm, maintaining appropriate tension, and ensuring stable coating effect, thus improving the practicality of the device and the coating quality.

[0029] The working principle and process of this utility model are as follows: During use, the glass door 35 can be rotated and opened by the plug shaft 36 and the hinge sleeve 34. The composite diaphragm to be processed is installed on the front feeding roller 4 and guide roller 5 of the coating machine 2, with one end passing through the adjustment component 6. Then, the glass door 35 is closed, and the inner magnetic strip 37 and the outer magnetic strip 38 are magnetically attracted and attached. At this time, the coating machine 2 can be used to coat the composite diaphragm. When the equipment needs to be adjusted, the glass door 35 can be opened, and the moving frame 64 and the guide rod 66 can be raised and lowered on the guide hole 65 by the threaded rod 63. The moving frame 64 drives the adjustment roller 67 and the guide slider 68 to rise and fall along the guide groove 62, so that the tension of the adjustment roller 67 on the composite diaphragm changes, which makes it easy to adjust the degree of stretching of the composite diaphragm, ensuring stable conveying and uniform coating.
