[0002] In the production of PCBs (Printed Circuit Boards), film application is a crucial step. The purpose of film application is to cover the PCB with a protective film to prevent damage to the board surface during subsequent processing (such as etching and drilling). Current film application methods include manual operation and automated mechanical application. Manual operation has difficulties in ensuring the flatness and alignment of the film, easily resulting in problems such as bubbles and wrinkles, affecting the quality of subsequent processing; while automated mechanical film application equipment is often complex in structure and expensive.

[0003] Therefore, developing an auxiliary film-applying device that is simple in structure, easy to operate, and adaptable to various PCB board specifications is of great practical significance. Utility Model Content

[0021] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figure 1-4 As shown, a PCB board auxiliary film application device includes a square worktable 1. Each of the four sides of the worktable 1 is equipped with a film stretching mechanism 2. Each film stretching mechanism 2 includes a movable seat 21 connected to a control component 22 for controlling its movement. The movable seat 21 has a groove 23 along its side parallel to the worktable end. Openings are provided at both ends of the groove 23 and on the side away from the worktable. The film stretching mechanism 2 also includes a film clamping member 24, which includes a slider 241 slidably connected within the groove 23, a mounting base 242 fixedly connected to the slider 241, and a clamp 243 mounted on the mounting base 242. By providing film stretching mechanisms 2 at the four sides of the worktable, the movable seat 21 in the film stretching mechanism 2 can move under the drive of the control component 22, thereby stretching the film. The clamping member 24 slides within the groove 23 via the slider 241, allowing for flexible adjustment of the clamping position and ensuring uniform stretching of the film in all directions. This design effectively prevents bubbles or wrinkles from forming during the film application process, improving the flatness and alignment of the film, while also adapting to PCB boards of different sizes, thus enhancing the versatility of the device.

[0024] Furthermore, the control component 22 includes a rotating shaft 221 rotatably connected to the worktable 1. One end of the rotating shaft extends to the outer end of the worktable and is threaded. The threaded end of the rotating shaft is threadedly connected to the movable seat 21. A rotating handle 223 is provided at the end of the threaded end away from the worktable. The control component 22 also includes a guide shaft 222, which is fixedly connected to the worktable 1 and slidably connected to the movable seat 21. The rotating shaft 221 is threadedly connected to the movable seat 21. Rotating the handle 223 drives the rotating shaft 221 to rotate, thereby moving the movable seat 21 along the guide shaft 222, achieving precise control of the film stretching mechanism. Through the cooperation of the threaded transmission and the guide shaft, the film stretching mechanism can move smoothly, ensuring a stable and reliable film stretching process. At the same time, it is simple to operate and reduces the difficulty of manual operation.

[0025] Furthermore, each of the movable seats 21 is provided with at least two clamping members 24. The design of multiple clamping members improves the stability and accuracy of film application and avoids the problems of film deformation or uneven stretching caused by single-point clamping.

[0026] Furthermore, the clamp 243 is a horizontal quick-release clamp. A clamping plate 2431 is connected to the clamping end of the clamp 243. A mounting base 242 has a fixing seat 2421 corresponding to the clamping plate 2431 at its lower end, forming a clamping space between the clamping plate 2431 and the fixing seat 2421. The horizontal quick-release clamp, through the cooperation of the clamping plate 2431 and the fixing seat 2421, can quickly clamp and release the membrane. The design of the clamping space ensures that the membrane will not be damaged during clamping. The use of the horizontal quick-release clamp improves operational efficiency. The cooperation between the clamping plate and the fixing seat ensures the firmness and stability of the clamping, preventing the membrane from falling off or shifting during stretching. The horizontal quick-release clamp is a commonly used quick-clamping component in the prior art and will not be described in detail here.

[0027] Furthermore, each clamping member 24 includes two clamps and a clamping plate. Each clamping plate 2431 is connected to two clamps 243, and a connecting plate 2432 is provided between the handles of the two clamps connected to the same clamping plate 2431. The connecting plate 2432 connects the handles of the two clamps 243 together, allowing the operator to control both clamps simultaneously by operating the connecting plate, achieving synchronous clamping or release. The connection of two clamps 243 to each clamping plate 2431 increases the stability of the clamping member.

[0028] Furthermore, one end of the film-pulling mechanism 2 is flush with the worktable, and the other end extends to the outer end of the worktable. The adjacent film-pulling mechanism 2, with its end extending to the outer end of the worktable, is also flush with the worktable. This structure facilitates the loading and unloading of clamping components and prevents mutual blockage of the sliding grooves.

[0029] Furthermore, the height of the clamping position of the fixture 243 is lower than or equal to the height of the PCB board on the workbench.

[0030] This utility model's PCB board auxiliary film-applying device achieves precise film stretching and fixing through the coordinated operation of a film-stretching mechanism, clamping components, and control components, significantly improving the flatness, alignment, and consistency of the applied film. Furthermore, the device has a simple structure, is easy to operate, and can adapt to PCB boards of different sizes and shapes, thus possessing broad application prospects.

[0031] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
