Description

Technical Field

[0001] This utility model relates to the field of coating processing, specifically to a photosensitive adhesive coating machine. Background Technology

[0002] Etching, as a precision image transfer technology, is widely used in PCB (Printed Circuit Board) manufacturing, signage production, and precision parts manufacturing. Its production process includes five core steps: pretreatment, photosensitive emulsion coating, exposure and development, chemical etching, and post-treatment. In the coating stage, a coating machine evenly coats the surface of the substrate to be processed, and then uses equipment such as a dryer to cure the photosensitive emulsion, forming a uniform photosensitive film. In the subsequent exposure and development processes, this photosensitive film selectively absorbs light energy and undergoes a chemical reaction according to the design pattern requirements, thereby forming a clear image on the photosensitive material.

[0003] Existing coating machines reduce the contact area with the substrate by incorporating a conical sleeve at the rear end of the coating roller assembly, thus preventing friction between the conveyor roller assembly and the photosensitive emulsion on the substrate and avoiding damage to the coating. However, due to the lack of a correction mechanism, manual adjustment of the substrate position is required during placement to ensure it aligns with the conical sleeve after coating. In high-volume production environments, prolonged and repetitive manual operation can lead to fatigue, resulting in errors, omissions, or untimely adjustments, thereby affecting production efficiency and coating quality. Therefore, this invention proposes an automatically correcting photosensitive emulsion coating machine. Summary of the Invention

[0004] This invention provides a photosensitive adhesive coating machine that achieves automatic deviation correction through the cooperation of a fixed plate, a sliding plate, and a driving component, thus solving the problem that existing coating machines require manual adjustment of the plate for deviation correction.

[0005] The objective of this utility model is achieved through the following means:

[0006] A photosensitive adhesive coating machine includes a support frame and a lower coating roller assembly fixedly mounted on the support frame. An upper coating roller assembly is slidably mounted on the upper end of the lower coating roller assembly. One side of the support frame is provided with output components that cooperate with the lower coating roller assembly and the upper coating roller assembly. The support frame is provided with a conveyor roller assembly that cooperates with the lower coating roller assembly. A plurality of conical sleeves are slidably mounted on the conveyor roller assembly. One end of the support frame is provided with a fixed plate and a sliding plate that cooperate with the conical sleeves. The fixed plate is fixedly mounted on the support frame, and the sliding plate cooperates with the fixed plate through a driving component.

[0007] Furthermore, there are two sliding plates, which are symmetrically arranged on both sides of the fixed plate.

[0008] Furthermore, push plates are installed on both the fixed plate and the sliding plate.

[0009] Furthermore, a limiting block is provided on one side of the push plate, and both the fixed plate and the sliding plate are provided with limiting grooves that cooperate with the limiting block.

[0013] Furthermore, the lower end of the lower coating roller assembly is provided with a downwardly inclined baffle, and a collection box that cooperates with the baffle is provided on one side of the support.

[0014] The beneficial effects of this invention are as follows: By setting the conical sleeve, the contact area between the conveyor roller assembly and the sheet material is reduced, thereby avoiding friction with the photosensitive adhesive on the sheet material, which could lead to scratches or damage to the coating.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. This embodiment refers to... Figures 1-6 The photosensitive adhesive coating machine specifically implemented therein includes a support 1 and a lower coating roller group 2 fixedly installed on the support 1. An upper coating roller group 3 is slidably installed on the upper end of the lower coating roller group 2. An output component 11 that cooperates with the lower coating roller group 2 and the upper coating roller group 3 is provided on one side of the support 1. The support 1 is provided with a conveying roller group 4 that cooperates with the lower coating roller group 2. Several conical sleeves 41 are slidably installed on the conveying roller group 4. A fixed plate 12 and a sliding plate 13 that cooperate with the conical sleeves 41 are provided at one end of the support 1. The fixed plate 12 is fixedly installed on the support 1, and the sliding plate 13 cooperates with the fixed plate 12 through a driving component 14.

[0023] The output component 11 is mounted on one end of the bracket 1 via a motor frame. Both sides of the motor frame are provided with waist-shaped grooves. The waist-shaped grooves allow the output component 11 to be mounted on the bracket in an adjustable manner to meet different working requirements.

[0024] Both the lower coating roller group 2 and the upper coating roller group 3 consist of two cooperating coating rollers and a back roller. The coating roller and the back roller are driven by meshing gears. One end of the coating roller is connected to the output component 11. Through the cooperation of the gears and the output component 11, the coating roller and the back roller rotate in opposite directions. The coating roller has grooves to control the amount of coating material. In use, the coating material is poured between the coating roller and the back roller, and the coating roller rotates to evenly apply the coating material to the board.

[0025] The conveyor roller group 4 consists of several drive rollers, which are linearly distributed on both sides of the lower coating roller group 2 along the material feeding direction and are rotatably mounted on the bracket 1 via bearings. A tapered sleeve 41 is bolted to the drive roller on the discharge side. The drive rollers rotate synchronously through the cooperation of sprockets and chains. A rotary motor connected to the drive rollers is mounted on the bracket 1. Driven by the rotary motor, the drive rollers rotate synchronously, thereby completing the feeding and discharging of the sheet material.

[0026] In this embodiment, the driving component 14 consists of a bidirectional threaded screw and a drive motor. There are two sliding plates 13, symmetrically arranged on both sides of the fixed plate 12. The fixed plate 12 is installed at the center of the bidirectional threaded screw, and the sliding plates 13 are symmetrically arranged at both ends of the bidirectional threaded screw via screw nuts. The drive motor is fixedly installed on one side of the bracket 1 and connected to the bidirectional threaded screw. When the drive motor rotates, it drives the bidirectional threaded screw to rotate, and the screw nuts cause the sliding plates 13 to move, thereby cooperating with the fixed plate 12 to adjust the plate material.

[0027] A guide rod is installed through one side of the bracket to cooperate with the sliding plate 13. The guide rod makes the sliding plate 13 more stable during movement and less prone to deviation or wobbling. The surface of the guide rod is finely polished to reduce friction with the sliding plate 13, making the sliding smoother and thus improving the operating efficiency of the equipment.

[0028] Furthermore, push plates 5 are installed on both the fixed plate 12 and the sliding plate 13. A limiting block 51 is provided on one side of the push plate 5, and both the fixed plate 12 and the sliding plate 13 are provided with limiting grooves 6 that cooperate with the limiting block 51. Through the cooperation of the limiting block 51 and the limiting grooves 6, the push plate 5 can be quickly installed between the fixed plate 12 and the sliding plate 13. One side of the push plate 5 is provided with a contact surface that cooperates with the sheet material; when the shape of the sheet material changes, a push plate 5 with a contact surface of the corresponding shape can be replaced.

[0029] Furthermore, the limiting block 51 is a T-shaped block or a dovetail block. In this embodiment, a T-shaped block is used as the limiting block 51, and the limiting groove 6 is cross-shaped. The cross-shaped limiting groove 6 allows push plates 5 to be installed on both sides of the fixed plate 12 and the sliding plate 13, thereby adapting to different usage requirements.

[0030] Both ends of the upper coating roller assembly 3 are equipped with adjusting plates 31. One end of each adjusting plate 31 has a rotatable adjusting rod 32. The bracket 1 has a support frame 15 that cooperates with the adjusting rod 32. The adjusting rod 32 is installed at one end of the adjusting plate 31 via a limiting plate, allowing it to rotate only at that end. The support frame 15 and the adjusting rod 32 are connected by a threaded connection. The other end of the adjusting rod 32 has a handle. In use, by turning the handle, the adjusting rod 32 engages with the support frame 15, causing the adjusting plate 31 to slide on the bracket 1, thereby adjusting the height of the upper coating roller assembly 3 to meet the coating requirements of materials of different thicknesses.

[0031] The support frame 1 is equipped with replenishment valves 7 that cooperate with the lower coating roller group 2 and the upper coating roller group 3. One end of the replenishment valve 7 is connected to an external liquid supply device. The support frame 1 is equipped with a support rod for fixing the replenishment valve 7, and the replenishment valve 7 is fixedly installed on the support rod by clamps. When the lower coating roller group 2 and the upper coating roller group 3 need to be replenished with paint, the replenishment valve 7 can be opened to replenish the paint. The flow rate of paint can be controlled by adjusting the size of the valve, thereby avoiding uneven coating caused by excessive or insufficient paint.

[0032] The lower end of the lower coating roller assembly 2 is equipped with a downwardly inclined baffle 8, and a collection box 16 that cooperates with the baffle 8 is provided on one side of the support 1. The baffle 8 is used to guide excess paint or spillage into the collection box 16, effectively preventing paint from dripping or splashing out of the work area and ensuring a clean and safe production environment. The collection box 16 is slidably installed on the support 1. When the paint in the box accumulates to a certain amount, the collection box 16 can be pulled out, and the paint can be poured out or recycled, thereby avoiding paint waste and environmental pollution during the production process.

[0033] The base of bracket 1 is equipped with feet and casters, allowing for flexible adjustment and ensuring stable and convenient movement and securing of the machine on various surfaces. The feet are designed to stabilize the machine when needed, preventing slippage or movement and ensuring accuracy and safety during the coating process. The casters allow for easy movement of the machine when required, facilitating relocation or position adjustment between different work locations. This design balances machine stability and flexibility, providing users with a better experience.

[0034] The beneficial effects of this utility model are as follows: By setting the conical sleeve 41, the contact area between the conveyor roller group 4 and the plate is reduced, thereby avoiding friction with the photosensitive adhesive on the plate, which could lead to scratches or damage to the coating. Furthermore, through the cooperation of the fixed plate 12, the sliding plate 13, and the driving component 14, automated adjustment of the plate is achieved, ensuring accurate alignment between the plate and the conical sleeve 41, thus improving production efficiency and coating quality.
