Technical Field

[0001] This utility model relates to the field of PCB processing equipment technology, and more specifically, to a PCB dry film pretreatment machine. Background Technology

[0002] A PCB dry film pretreatment machine is a specialized piece of equipment used in the manufacturing process of printed circuit boards (PCBs) to clean and roughen the surface of copper foil before applying dry film. Its purpose is to remove contaminants such as oxide layers and oil stains, and to increase the roughness of the copper surface, ensuring good adhesion between the dry film and the substrate.

[0003] In PCB manufacturing, surface cleaning before dry film lamination is crucial. Its purpose is to remove oxide layers, oil, and other contaminants from the copper surface to ensure good adhesion between the dry film and the substrate. However, existing PCB dry film pretreatment machines typically use a fixed-height cleaning roller design, which limits their flexibility to adapt to PCBs of different thicknesses or surface conditions, thus restricting the equipment's versatility and process adaptability. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a PCB dry film pretreatment machine, which has the advantage of being able to adjust the height and position of the cleaning roller, making it adaptable to PCB boards of different thicknesses, and thus solving the problems mentioned in the background technology.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned advantages of adjustable height and position of the cleaning roller, enabling it to adapt to PCB boards of varying thicknesses and exhibiting strong adaptability, the specific technical solution adopted by this utility model is as follows:

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a PCB dry film pretreatment machine, which has the following beneficial effects:

[0018] (1) In this utility model, the PCB board is placed between two parallel cleaning rollers. The cleaning rollers are rotated by a servo motor driven by a synchronous wheel and a synchronous belt, thereby realizing automated cleaning of the board surface, effectively removing oxide layer and contaminants, and ensuring the quality of subsequent dry film bonding process. In order to adapt to PCB boards of different thicknesses, a dual-axis motor is started, and the dual-axis motor drives the screw to rotate. The moving block is constrained by the connecting groove and the connecting block, so that the moving block is precisely displaced along the screw axis. The moving block is rigidly connected to the mounting frame, driving the cleaning rollers to move synchronously, thereby realizing the adjustment of the distance between the two cleaning rollers. This solves the compatibility problem of traditional fixed cleaning rollers and improves the equipment's processing adaptability and process consistency for PCB boards of different specifications.

[0019] (2) In this utility model, by opening the bidirectional electric push rod at the middle position of the upper surface of the bottom of the base, the bidirectional electric push rod drives the extension plate to move. When the extension plate moves out of the base, it can increase the contact area between the base and the ground, thereby improving its anti-slip effect. In turn, it can effectively improve the equipment's resistance to displacement under high-speed operation or load change conditions, ensuring the working stability of the equipment under different ground conditions and making it convenient to use.

[0027] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0028] According to an embodiment of the present invention, a PCB dry film pretreatment machine is provided.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a PCB dry film pretreatment machine according to an embodiment of the present invention includes a base 1. Support plates 2 are provided on both sides of the top surface of the base 1. A dual-axis motor 3 is fixedly installed at the middle position of one side surface of the support plate 2. A screw 10 is fixedly connected to the output end of the dual-axis motor 3, and a moving block 11 is threadedly connected to the screw 10. Connecting grooves 13 are provided through the support plate 2 on both sides of the dual-axis motor 3. A connecting block 12 is fixedly connected through the connecting groove 13 on one side surface of the moving block 11. A mounting frame 6 is fixedly connected between the connecting blocks 12. A cleaning roller 5 is mounted on the mounting frame 6. A servo motor 16 is fixedly installed on one side of the top surface of the mounting frame 6. A synchronous wheel 14 is fixedly installed at the output end of the servo motor 16 and on the cleaning roller 5. A synchronous belt 15 passes through the mounting frame 6 between the synchronous wheels 14. A bidirectional electric push rod 8 is fixedly installed at the middle position of the upper surface of the bottom end of the base 1, and the output end of the bidirectional electric push rod 8... An extension plate 9 is fixedly connected, with one end of the extension plate 9 extending through the openings 4 on both sides of the base 1 to one side of the base 1. The PCB board is placed between two parallel cleaning rollers 5. The synchronous pulley 14 and synchronous belt 15 are driven by a servo motor 16 to drive the cleaning rollers 5 to rotate, realizing automated cleaning of the board surface, effectively removing oxide layers and contaminants, and ensuring the quality of subsequent dry film bonding. To adapt to PCB boards of different thicknesses, a dual-axis motor 3 is started, which drives the screw 10 to rotate. The moving block 11 is motion-constrained by the connecting groove 13 and the connecting block 12, so that the moving block 11 is precisely displaced along the axial direction of the screw 10. The moving block 11 is rigidly connected to the mounting frame 6, driving the cleaning rollers 5 to move synchronously, thereby realizing the adjustment of the distance between the two cleaning rollers 5. This solves the compatibility problem of the traditional fixed cleaning rollers 5 and improves the equipment's processing adaptability and process consistency for PCB boards of different specifications.

[0030] In one embodiment, a through groove 7 is provided on the top surface of the base 1 directly below the servo motor 16. The length and width of the through groove 7 are greater than the length and width of the servo motor 16. The use of the through groove 7 can maintain the normal movement of the servo motor 16 and prevent the base 1 from affecting the movement of the servo motor 16.

[0031] In one embodiment, the connecting block 12 and the connecting groove 13 are rectangular structures. The connecting block 12 and the connecting groove 13 are slidably connected, allowing the connecting block 12 to move within the connecting groove 13. This, in turn, drives the cleaning rollers 5 on the mounting frame 6 to move, facilitating the adjustment of the distance between the cleaning rollers 5.

[0032] In one embodiment, the extension plate 9 is matched with the base 1 and is movably connected to the through port 4. By opening the bidirectional electric push rod 8 located at the middle position of the upper surface of the bottom end of the base 1, the bidirectional electric push rod 8 drives the extension plate 9 to move. When the extension plate 9 moves out of the base 1, it can increase the contact area between the base 1 and the ground, thereby improving its anti-slip effect. This can effectively improve the equipment's resistance to displacement under high-speed operation or load change conditions, ensuring the stability of the equipment under different ground conditions and facilitating its use.

[0033] In one embodiment, there are two cleaning rollers 5, and the two cleaning rollers 5 are evenly distributed between the support plates 2.

[0034] In one embodiment, the support plate 2 is fixedly connected to the base 1, which can maintain the stability of the support plate 2 on the base 1.

[0035] In one embodiment, a maintenance plate 17 is provided on the front surface of the base 1, and the maintenance plate 17 is fixedly connected to the base 1 by screws. By loosening the screws and removing the maintenance plate 17, the components in the base 1 can be maintained and repaired.

[0036] In one embodiment, the bottom surface of the base 1 is provided with an anti-slip pad, which improves the anti-slip effect of the base 1 and increases the friction between the base 1 and the ground, thereby maintaining the stability of the base 1 during use.

[0037] In one embodiment, the control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0038] Working principle: The PCB board is placed between two parallel cleaning rollers 5. A servo motor 16 drives a synchronous pulley 14 and a synchronous belt 15 to rotate the cleaning rollers 5, achieving automated cleaning of the board surface. This effectively removes oxide layers and contaminants, ensuring the quality of subsequent dry film bonding. To accommodate PCB boards of different thicknesses, a dual-axis motor 3 is activated, driving a screw 10 to rotate. The moving block 11 is motion-constrained by the connecting groove 13 and connecting block 12, allowing precise axial displacement of the moving block 11 along the screw 10. The moving block 11 is rigidly connected to the mounting frame 6, driving the cleaning rollers 5 to move synchronously. The movement of the two cleaning rollers 5 allows for adjustment of the distance between them, solving the compatibility problem of the traditional fixed cleaning rollers 5 and improving the equipment's adaptability and process consistency for PCB boards of different specifications. Specifically, by opening the bidirectional electric push rod 8 located in the middle of the upper surface of the bottom of the base 1, the bidirectional electric push rod 8 drives the extension plate 9 to move. When the extension plate 9 moves out of the base 1, it can increase the contact area between the base 1 and the ground, thereby improving its anti-slip effect. This can effectively improve the equipment's resistance to displacement under high-speed operation or load changes, ensuring the equipment's working stability under different ground conditions and facilitating its use.
