Description

Technical Field

[0001] This invention relates to the field of printing equipment technology, specifically to a film plate punching and positioning integrated machine. Background Technology

[0002] Currently, the fully automatic flatbed screen printing machine features a modular design, a high-strength aluminum alloy structure, and a high-precision servo drive for the main rotation system. The machine operates quickly and smoothly, with precise registration, reliable performance, and easy operation, enabling multi-color screen printing in a single pass. The film plate on this machine is a printing screen that is attached to a mesh screen. During the screen printing exposure process, the relative position of the film on the film plate and the screen printing frame determines the left-right centering of the content on the screen. Therefore, the selection and fixing of the relative position of the film determines the accuracy of the screen printing content. After the film is attached, holes need to be punched on both sides of the screen frame. The hole positions must be adapted to the film and the screen printing machine to fix the film plate on the machine, allowing the image on the film plate to be printed onto the object to be printed.

[0003] Currently, film positioning and punching are generally completed using two separate devices: a film positioner and a punching machine. Typically, the film is first positioned using the film positioner, then transferred to the punching machine for manual positioning and punching. This transfer between devices requires manpower and resources, increasing production costs. Furthermore, since fully automatic flatbed screen printing machines need to install multiple film plates simultaneously, each plate requires manual calibration and positioning during punching. This is not only time-consuming but also results in poor positioning accuracy, leading to punching errors that severely impact printing quality. Moreover, due to the poor punching accuracy, each film plate needs to be adjusted and corrected along its XYZ axes when mounted on the screen printing machine, further consuming time and labor and significantly reducing production efficiency. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a film-based punching and positioning integrated machine that can simultaneously realize film positioning and wireframe punching functions.

Detailed Implementation

[0030] To enhance understanding of the present invention, it will be further described in detail below with reference to embodiments and accompanying drawings. The present invention can be implemented in the following ways:

[0031] Reference Figure 1-4 A film punching and positioning integrated machine includes a frame 1 and a wire frame fixing structure and a film positioning structure disposed on the frame 1.

[0032] The frame 1 is equipped with a guide rail 2. The screen frame fixing structure includes a front baffle 3 and a rear baffle 4 for clamping the front and rear edges of the screen frame, respectively. The rear baffle 4 is slidably connected to the guide rail 2. Both the front baffle 3 and the rear baffle 4 are equipped with two drill sleeves 5 for drilling. The distance between the two drill sleeves 5 is adapted to the fixing points of the screen frame on the screen frame fine-tuning structure of the screen printing machine, and is usually set to 320mm. When the film plate is installed on the screen printing machine, fixing glue pellets need to be installed at the holes of the film plate. When the glue pellets at the holes of the film plate wear out after long-term use, holes can be drilled at other positions on the original screen frame to achieve reuse of the screen frame.

[0033] Both the front baffle 3 and the rear baffle 4 include a top plate 341, a side plate 342, and a bottom plate 343, which are sequentially connected to form an inward-facing "C"-shaped plate. The "C"-shaped plate is designed to clamp the edge of the film frame. The drill sleeve 5 penetrates the side plate 342 and is equipped with a bearing 51. After the front baffle 3 and the rear baffle 4 clamp the frame, the drill bit of the punch can be inserted into the drill sleeve 5 for drilling. During drilling, the bearing 51 inside the drill sleeve 5 rotates with the drill bit.

[0034] A rotating copper sleeve 6 is provided at the midpoint of the base plate 343 of the front baffle 3. The rotating copper sleeve 6 passes through the base plate 343, and its bottom is fixedly connected to the guide rail 2. The front baffle 3 has fixing holes 61 at both ends of the rotating copper sleeve 6 for fixing the front baffle 3 to the guide rail 2. By inserting screws into the fixing holes 61, the front baffle can be firmly fixed to the guide rail. The front baffle 3 can rotate around the rotating copper sleeve 6. When encountering an irregular or deformed mesh frame, the screws on the fixing holes 61 can be unscrewed, and the front baffle 3 can be rotated so that the side plate 342 of the front baffle 3 can fit tightly against the edge of the mesh frame. The rotatable design of the front baffle 3 increases the adjustability of the mesh frame fixing structure and expands its adaptability.

[0035] The rear baffle 4 has a rear baffle sliding assembly 41 at its bottom, which drives the rear baffle 4 to slide along the guide rail 2. A rear baffle drive source 42 is provided on the outer side of the rear baffle 4 to control its reciprocating movement. The rear baffle sliding assembly 41 includes a rear baffle mounting plate 411 at the bottom of the rear baffle 4, and a rear baffle slider 412 slidably connected to the bottom of the guide rail 2 on the rear baffle mounting plate 411. Both ends of the bottom plate 343 of the front baffle 3 and the rear baffle 4 are provided with clamping plates 7. One end of the clamping plate 7 penetrates the bottom plate 343, and the other end is provided with a clamping plate drive source 71 to control the up-and-down movement of the clamping plate 7. The front baffle 3 and the rear baffle 4 restrict the movement of the mesh frame in the X and Y axes, while the clamping plate 7 restricts the movement of the mesh frame in the Z axis. When drilling, first place one side of the mesh frame against the front baffle 3. Then, the rear baffle drive source 42 pushes the rear baffle 4 to move towards the mesh frame until the rear baffle 4 clamps the other side of the mesh frame. Finally, the top plate drive source 71 controls the top plate 7 to rise and tighten the mesh frame.

[0036] The film positioning structure is located between the front baffle 3 and the rear baffle 4, and the film positioning structure and the guide rail 2 are located on the center line where the midpoints of the two drill sleeves 5 are located. The film positioning structure includes a front film positioner 8 and a rear film positioner 9 located between the front baffle 3 and the rear baffle 4, and the rear film positioner 9 is slidably connected to the guide rail 2. The front film positioner 8 is used to fix the first and second positions of the film, and then the rear film positioner 9 is dragged until it is aligned with the other positioning points of the film.

[0037] The front film positioner 8 includes a front lamp holder 81, a lamp tube (not shown in the figure) disposed inside the front lamp holder 81, a first transparent cover plate 82 disposed on the top of the front lamp holder 81, and a front lamp holder mounting plate 83 that fixes the front lamp holder 81 to the guide rail 2. The first transparent cover plate 82 has several cross-shaped positioning marks 84. The rear film positioner 9 includes a rear lamp holder 91, a lamp tube disposed inside the rear lamp holder 91, a second transparent cover plate 92 disposed on the top of the rear lamp holder 91, and a rear lamp holder mounting assembly 93 that movably mounts the rear lamp holder 91 to the guide rail 2. The second transparent cover plate 92 has cross-shaped positioning marks 84. Both the front and rear film positioners 8 and 9 use red light, which can penetrate the first and second transparent cover plates 82 and 92, increasing the accuracy of film positioning. The rear lamp holder mounting assembly 93 includes a rear lamp holder mounting plate 931 disposed at the bottom of the rear lamp holder 91, and a rear lamp holder slider 932 slidably connected to the bottom of the guide rail 2 on the rear lamp holder mounting plate 931. The center point of the cross-shaped positioning mark 84 of the front film positioner 8 and the rear film positioner 9 is located on the center line where the midpoints of the two drill bushings 5 ​​are located. The top plate 341 of the front baffle 3 and the rear baffle 4 is provided with a positioning sharp angle 344 at the midpoint of the side facing the film positioning structure, which can further improve the accuracy of film positioning. When applying the film, the midpoint of the film is aligned with the crosshair 84 on the front film positioner 8 and the rear film positioner 9. This ensures that the midpoint of the film is always aligned with the midpoint of the two drill sleeves 5 on the front baffle 3 or the rear baffle 4, guaranteeing that the content on the film is always centered horizontally. This eliminates the need for manual positioning and drilling, and the film plate can be directly installed on the screen printing machine after drilling and application. This creates a precise closed loop between the film plate and the screen printing machine, eliminating the need for significant adjustments and corrections to the XYZ axes of each film plate. This reduces the time required for setting up the screen printing machine and significantly improves production efficiency.

[0038] Working principle: The operation steps of the film punching and positioning integrated machine of the present invention are punching, positioning, and film application. First, one side of the mesh frame is abutted against the front baffle 3. The rear baffle drive source 42 pushes the rear baffle 4 to move towards the mesh frame until the rear baffle 4 clamps the other side of the mesh frame. Finally, the top clamping plate drive source 71 controls the top clamping plate 7 to rise and tighten the mesh frame. After the front baffle 3 and the rear baffle 4 clamp the mesh frame, the drill bit of the punch is inserted into the four drill sleeves 5 in sequence to punch holes. After punching, the positioning point on the film is aligned with the "+" positioning mark 84 of the front film positioner 8 and the rear film positioner 9. After the film is firmly attached to the mesh, the rear baffle 4 and the top clamping plate 7 are released, the mesh frame is removed, and the adhesive granules are stuffed into the holes of the mesh frame for use.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
