Description

Technical Field

[0001] This invention relates to the field of hot stamping plate production equipment technology, specifically a replacement device that can accurately correct the position of hot stamping plates. Background Technology

[0002] Hot stamping plates are made of copper or zinc relief plates. Copper plates have good heat transfer performance, are pressure-resistant, wear-resistant, and not easily deformed. They are generally used for hot stamping of repetitive long-term orders or long-run hot stamping jobs. The exposure steps for copper and zinc plates are as follows: ① Plate base grinding; ② Coating with photosensitive liquid; ③ Exposure; A latent image is formed on the metal plate surface. A positive negative film is placed on the metal plate surface coated with photosensitive film. Exposure is performed using a blue-violet light source with a wavelength range of about 360nm. The transparent parts of the negative film harden and lose their original water solubility through the light, while the unexposed photosensitive film retains its water solubility. ④ Development; ⑤ Baking; To drive away the moisture in the photosensitive film on the plate surface and make it porcelain to have high acid and corrosion resistance, the plate is placed in an oven at 180-200℃ and baked for 10-20 minutes. The plate surface is uniformly dark chestnut brown and glossy. ⑥ Repairing the plate; scraping away dirt, residual glue, and smeared lines with a scraper; filling in broken lines with repair ink made of asphalt or varnish and turpentine using a brush, and then heating and baking; ⑦ Etching; zinc plates are etched with dilute nitric acid, and copper plates are etched with ferric chloride to etch and depress the blank areas of the plate.

[0003] For hot stamping dies, square hot stamping dies are more common. During the exposure process, the precise positioning of the die base is crucial, directly impacting the quality of the final hot stamping die. Before exposure, a negative film needs to be placed over a metal plate coated with a photosensitive film. The precise positioning of the metal plate during this process is critical, directly affecting the quality of the latent image formed on the metal plate, which in turn indirectly affects the quality of the exposure process, ultimately impacting the product quality. Existing methods lack effective die base positioning and correction mechanisms, requiring manual adjustments by workers, causing inconvenience, significantly reducing work efficiency, and lowering economic benefits. Therefore, this invention proposes a replacement device for precise die positioning correction to solve the aforementioned problems. Summary of the Invention

[0043] Working principle: First, the substrate to be processed is placed on the placement platform on the upper section of the movable support block 16. Then, the positions of the arc-shaped slide rod 7 and the arc-shaped limiting block 8 are adjusted and fixed in place. Next, the first knob 12 is rotated, which in turn drives the rotation of the second gear 11 and the first gear 10, thereby driving the rotation of the box body 15 and the fixing plate 21. Rotation stops when the fixing plate 21 contacts the arc-shaped limiting block 8. The first knob 12 is then fixed in place by the fixing structure 14. During this process, the first pressing screw 1402 is turned, thereby pushing the second insert block 1404. The knob 12 enters the annular groove 13 on its side. The compression spring 1406 and compression block 1407 in the second insert 1404 exert a compression force on the inner wall of the annular groove 13, thus fixing the position of the first knob 12. This completes the fixing of the box 15 to the fixing plate 21. Then, by rotating the second knob 19, the transmission of the first rack 17 and the third gear 18 is driven, ultimately moving the placement platform upwards. When it reaches the appropriate position, the positioning block 2201 in the positioning and correction device 22 positions and limits the side wall of the plate base. In the initial position, the positioning block 2201 is pushed to contact the side wall of the base plate and fixed in place by the second positioning spring pin 2205. Then, the movable block 2208 is pulled, and the second pressing screw 2209 is pushed, so that the correction block 2210 is on top of the base plate. The second pressing screw 2209 is then rotated, so that the correction block 2210 contacts the upper surface of the base plate, releasing the movable block 2208. The movable block 2208 returns to its initial position under the action of the second return spring 2207. Afterwards, a negative film can be applied to the metal plate. Once one round of processing is completed, the fixed position is then adjusted by pulling... Spring pin 3 separates from fixed circular groove 4, and replacement plate 2 is removed from workbench 1. Processed plate base is removed, and plate base to be processed is placed directly on the placement table. Position is limited by positioning block 2201, and the placement position of plate base is precisely corrected by correction block 2210. Then, replacement plate 2 is fixed on workbench 1. With this invention, after one round of plate processing is completed, the plate can be quickly placed in the optimal processing position for the next round of plate processing, bringing convenience to the staff, saving working time, thereby improving work efficiency and ensuring economic benefits.
