Abstract
Description
Technical Field
[0001] This invention relates to the field of screen printing fixtures for glass covers, and particularly to a fixture for screen printing on glass covers. Background Technology
[0002] Because the internal cavity of the screen printing fixture for the glass cover is the same size as the glass cover, it is difficult to pick up and put down the glass cover. When the glass is removed after the surface printing of the glass cover is completed, the staff will inevitably touch the printed surface of the glass, which will damage the pattern on the printed surface of the glass cover and seriously affect the quality of the surface printing of the glass cover.
[0003] To address this, a glass cover screen printing fixture, such as the one with patent number CN220615188U, was developed. While it solves the aforementioned problems to some extent, it still has the following drawbacks: when processing products of different specifications, it is necessary to replace the fixture plate with one that has a different mold cavity. This fixture plate has a large area, high weight, and complex structure, making it difficult to replace. In addition, after the glass cover is ejected from the mold cavity, it is not easy to remove it from the template. Furthermore, during the ejection process, the entire side wall of the glass cover rubs against the side wall of the mold cavity, which can easily affect its safety. Summary of the Invention
[0004] The purpose of this invention is to provide a computer wiring harness device.
[0005] The technical problem of this invention is mainly solved by the following technical solution:
[0006] A fixture for screen printing on glass covers includes a base, a boss on the top of the base, a disc on the top of the boss, and cuts on both sides of the disc to cut it off. The two sets of cuts divide the disc into a support part in the middle and positioning parts on both sides. The bottom of the corresponding ends of the positioning parts and the support parts are fixed by hinges. A U-shaped plate is movably disposed in the opening of the positioning part and is in contact with its inner wall. An elastic element connected to the base is disposed at the bottom of the positioning part. A sliding opening is provided on the boss, and a horizontal plate extending to its outer side and used to support the corresponding positioning part is disposed in the sliding opening. The horizontal plate is driven by an electric push rod.
[0007] An adsorption tank is also provided on the bottom wall inside the opening of the support section, and the adsorption tank is connected to a vacuum pump through a pipe.
[0008] Preferably, mounting holes are provided on both sides of the base, and a strip-shaped seat for fixing the bottom end of the elastic element is provided on the top of the base, wherein the elastic element is made of spring.
[0009] Preferably, the top of the end of the horizontal plate is provided with a support block that abuts against the bottom surface of the corresponding positioning part, and the support block is located between the corresponding hinge and the elastic element.
[0010] Preferably, the side wall of the positioning part is provided with bolts for locking and fixing the corresponding C-shaped plate.
[0011] Preferably, both ends of the bottom of the opening of the support part are provided with notches to accommodate magnetic blocks, the top of the magnetic block and the bottom wall of the opening of the support part are at the same horizontal plane, and the magnetic block and the corresponding end face of the positioning part are attached to each other.
[0012] Preferably, the inner bottom wall of the sliding opening is provided with a receiving groove for accommodating the electric push rod, and a ring of slots is provided around the inner bottom wall of the sliding opening outside the receiving groove. The bottom of the horizontal plate is provided with a cylinder whose bottom end is inserted into the slot, and the cylinder is sleeved on the output shaft of the electric push rod.
[0013] The beneficial effects of this invention are as follows: When processing products of different specifications, only two sets of C-shaped plates need to be replaced, making the replacement more convenient and quick. At the same time, when the glass cover is removed, the positioning part rotates downward so that the end of the glass cover is suspended outside the support part, making it easier for people to pick up the glass cover and remove it. Furthermore, when the glass cover is removed, the side wall of the C-shaped plate and the side wall of the support part rub against the corresponding side wall of the glass cover one by one, preventing the entire outer wall of the glass cover from rubbing against the inner wall of the component that fixes it at the same time, thereby reducing the probability of damage when the glass cover is removed.

[0018] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0019] A fixture for screen printing on a glass cover includes a base 1, a boss 2 on the top of the base 1, a disc 3 on the top of the boss 2, and cuts 33 on both sides of the disc 3 to cut it off. The two sets of cuts 33 divide the disc 3 into a support part 31 located in the middle and positioning parts 32 located on both sides. The bottom of the corresponding ends of the positioning parts 32 and the support parts 31 are hinged and fixed by hinges 4.
[0020] The positioning part 32 has a U-shaped plate 5 that is movably disposed inside the opening and is in contact with its inner wall. The positioning part 32 has a bolt 6 on its side wall that locks and fixes the corresponding U-shaped plate 5. The bottom of the positioning part 32 has an elastic element 7 that is connected to the base 1. The protrusion 2 has a sliding opening 8. The sliding opening 8 has a horizontal plate 9 that extends to its outer side and is used to support the corresponding positioning part 32. The horizontal plate 9 is driven by an electric push rod 10.
[0021] An adsorption tank 11 is also provided on the bottom wall inside the opening of the support part 31, and the adsorption tank 11 is connected to the vacuum pump through a pipe.
[0022] In this embodiment, mounting holes 12 are provided on both sides of the base 1, and a strip seat 13 for fixing the bottom end of the elastic element 7 is also provided on the top of the base 1. The elastic element 7 is made of spring.
[0023] like Figure 2 , 3 As shown, a support block 14 is provided at the top end of the horizontal plate 9, which abuts against the bottom surface of the corresponding positioning part 32. The support block 14 is located between the corresponding hinge 4 and the elastic member 7. Both ends of the bottom of the opening of the support part 31 are provided with notches to accommodate magnetic blocks 15. The top of the magnetic block 15 is on the same horizontal plane as the bottom wall of the opening of the support part 31. The magnetic block 15 is attached to the corresponding end face of the positioning part 32. When the horizontal plate 9 and the support block 14 support the positioning part 32, so that the support part 31 and the positioning part 32 form a complete disc 3 in the horizontal state, the magnetic block 15 has a magnetic attraction effect on the positioning part 32 to strengthen the connection stability between the support part 31 and the positioning part 32 and reduce the squeezing force caused by the positioning part 32 on the support block 14 and the horizontal plate 9.
[0024] like Figure 2 , 3As shown, the inner bottom wall of the sliding opening 8 is provided with a receiving groove for accommodating the electric push rod 10. A retaining groove 16 is arranged around the inner bottom wall of the sliding opening 8 outside the receiving groove. The bottom of the horizontal plate 9 is provided with a cylinder 17 whose bottom end is inserted into the retaining groove 16. The cylinder 17 is sleeved on the output shaft of the electric push rod 10. The cylinder 17 protects the output shaft of the electric push rod 10 from contact with external impurities and damage. At the same time, when the electric push rod 10 drives the horizontal plate 9 to move up and down, it can drive the cylinder 17 to move in the same direction and with the same amplitude within the retaining groove 16.
[0025] The method of using this invention is as follows: During use, the device is fixed to the corresponding position on the screen printing equipment by installing screws inside the mounting holes 12, and then... Figure 1 , 2 As shown, the horizontal plate 9 and the support block 14 support the positioning part 32, so that the support part 31 and the positioning part 32 in the horizontal state form a complete disc 3. At this time, the C-shaped plate 5 is replaced according to the size of the glass cover plate of the processing batch, so that when the C-shaped plate 5 is placed in the positioning part 32 and locked by the bolt 6, the size of the opening formed between the two sets of C-shaped plates 5 is adapted to the size of the glass cover plate. Then the glass cover plate is placed between the two sets of C-shaped plates 5 and fixed horizontally. At the same time, the support part 31 and the positioning part 32 support and fix the bottom of the glass cover plate. The vacuum pump also evacuates the adsorption tank 11 through the pipeline to further enhance the stability of the glass cover plate on the support part 31.
[0026] When the screen printing is complete and the glass cover needs to be removed, such as Figure 3 As shown, the electric push rod 10 drives the horizontal plate 9 to move downward in the sliding opening 8. At this time, the horizontal plate 9 and the support block 14 are no longer supported. Then the elastic element 7 contracts to pull the corresponding positioning part 32 to rotate downward with the hinge 4 as the center. This causes the two ends of the glass cover to slide out from the opening of the corresponding U-shaped plate 5 and the positioning part 32, so that the two ends of the glass cover are suspended at both ends of the support part 31. At this time, people can pick up the bottom of the two ends of the glass cover and vent the suction groove 11. In this way, the glass cover can be removed from the support part 31 without contacting its top silk screen end face.
[0027] Next, the electric push rod 10 drives the horizontal plate 9 to move upward, causing the positioning part 32 to reset and the elastic element 7 to stretch, thus preparing for the next processing work. When processing products of different specifications, this invention only requires replacing two sets of C-shaped plates 5, making the replacement more convenient and quick. At the same time, when the glass cover is removed, the positioning part 32 rotates downward, causing the end of the glass cover to be suspended outside the support part 31, which makes it easier for people to pick up the glass cover and remove it. Furthermore, when the glass cover is removed, the side wall of the C-shaped plate 5 and the side wall of the support part 31 rub against the corresponding side wall of the glass cover one by one, preventing the entire outer wall of the glass cover from rubbing against the inner wall of the component that fixes it at the same time, thereby reducing the probability of damage when the glass cover is removed.
[0028] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
