Description

Technical Field

[0001] The utility model mainly relates to the technical field of screen printing tooling fixtures, and particularly relates to a screen printing tooling fixture for curved glass. Background Art

[0002] A screen printing fixture is a tool and equipment for assisting the screen printing process, and is mainly applied to industries such as electronics, glass, and ceramics to achieve the correct placement of printed patterns and high-quality printing. The design and manufacture of screen printing fixtures aim to improve production efficiency, ensure printing quality, and reduce production costs at the same time.

[0003] For example, Chinese Patent Publication No. CN220615188U discloses a fixture for screen printing glass covers, which includes: a base and a fixture plate. The fixture plate is arranged above the base, and columns are arranged at the four corners of the top of the base. The four corners of the fixture plate are respectively inserted into the tops of the four columns. A cavity for placing the glass cover is opened inside the fixture plate, a template for lifting and supporting the glass cover is snap-fitted at the bottom of the cavity, and suction cups for defining the position of the glass cover are respectively embedded at both ends of the top of the template.

[0004] The fixture for screen printing glass covers in the above application can take out the glass cover without touching the glass cover, avoiding the trouble of damage to the printed pattern caused by touching the printing surface of the glass cover, ensuring the printing quality of the glass cover, and can also perform double positioning on the glass cover, avoiding the situation that the glass cover tilts in the cavity due to incomplete contact with the template, improving the stability of the glass cover, and ensuring the printing effect of the glass cover.

[0005] However, the currently used screen printing fixture is a single screen printing fixture, which can only screen print one piece of glass at a time, resulting in low production efficiency. At the same time, when screen printing curved glass, the curvature of the curved surface makes the flow of the ink on its surface complex. The curvature change of the curved surface will affect the distribution of the ink. In areas with a large curvature, the ink may flow downward due to the action of gravity and surface tension, causing local ink accumulation or shortage. In areas with a small curvature, the adhesion of the ink may decrease, also resulting in insufficient ink supply. Therefore, when screen printing curved glass, situations such as missing, overflowing, and serrations will occur. Summary of the Utility Model

[0006] 1. Technical problems to be solved by the utility model:

[0007] The utility model provides a screen printing tooling fixture for curved glass to solve the technical problems existing in the above background art.

[0008] 2. Technical solutions:

[0009] To achieve the above object, the technical solution provided by the present utility model is: a silk screen tooling fixture for curved glass, including a fixture plate, two fixture grooves are opened on the fixture plate, a glass placement table is arranged at the center of the fixture groove, a glass limiting edge is arranged around the glass placement table, a diversion groove is arranged outside the glass placement table, the diversion groove is an inner concave arc surface, a plurality of vacuum adsorption holes are arranged in a rectangular array on the glass placement table, and a secondary groove is opened at the center of the glass placement table.

[0010] Preferably, a groove center point is arranged at the center of the secondary groove.

[0011] Preferably, the bottom surface of the secondary groove is a square structure, and the side length of the secondary groove is 60 mm.

[0012] Preferably, the included angle between the long side of the glass placement table and the long side of the fixture plate is 45°.

[0013] Preferably, the overall length of the fixture plate is 1070 mm, the width is 370 mm, the position of the groove center point is 185 mm away from each upper and lower edge, the length of the glass placement table is 250 mm, and the width is 186 mm.

[0014] 3. Beneficial effects:

[0015] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0016] Through the setting of two fixture grooves, the present utility model can screen-print two pieces of curved glass at a time. Compared with the single-groove fixture, more printing tasks can be completed in the same time, greatly improving the production quantity. Since two pieces of curved glass can be printed simultaneously, the operator does not need to frequently replace the glass and adjust the fixture, reducing the number of operations and time waste. This not only reduces the labor intensity but also improves the work coherence, further enhancing the production efficiency.

[0017] The fixture groove of the present utility model can make the ink form an effect similar to "slantwise propulsion" during the flowing process. The ink flows from the higher end to the lower end. Due to the existence of the inclination angle, a certain inertial force will be generated during the flowing process of the ink. This inertial force helps to push the ink forward, increasing the fluidity and ink supply amount of the ink, improving the ink supply amount of silk screen printing, and thus avoiding sawtooth, missing, overflow, etc. in the printed pattern.

Embodiment

[0029] Referring to the attached Figures 1 to 4 , a screen printing tooling fixture for curved glass, includes a fixture plate 1. There are two fixture grooves 2 opened on the fixture plate 1. A glass placement table 5 is arranged at the center of the fixture groove 2. A glass limiting edge 4 is arranged around the glass placement table 5. A diversion groove 3 is arranged outside the glass placement table 5. The diversion groove 3 is an inward concave arc surface. A plurality of vacuum adsorption holes 6 are arranged in a rectangular array on the glass placement table 5. A secondary groove 7 is opened at the center of the glass placement table 5.

[0030] The included angle between the long side of the glass placement table 5 and the long side of the fixture plate 1 is 45°. This angle design can make the glass more stable in the fixture, and at the same time, it is convenient for the operator to perform screen printing operations, improving work efficiency. The inward concave arc surface of the diversion groove 3 is similar to the inner wall of a pot, with a smooth and continuous curved surface and no obvious edges or mutations. The design of the inward concave arc surface of the diversion groove 3 can effectively guide the flow of the ink, making the ink cover the glass surface more evenly. This helps to improve the printing quality and uniformity, and avoid the situation of ink accumulation or missing.

[0031] The design of multiple vacuum adsorption holes 6 can generate a strong adsorption force to firmly fix the glass on the glass placement table 5, preventing the glass from moving due to external forces during the printing process.

[0032] The design of the secondary groove 7 can enhance the adsorption force between the glass and the groove, further improving the stability of the glass in the fixture. Especially for some curved glass with larger weight or irregular shapes, the secondary groove 7 can provide better support and fixing effects.

[0033] At the center of the secondary groove 7, there is a groove center point 8. The setting of the groove center point 8 at the center of the glass placement table 5 and the glass limiting edge 4 can ensure the accurate placement of the glass in the fixture groove 2, improving the position accuracy of the printed pattern. The bottom surface of the secondary groove 7 is of a square structure, and the side length of the secondary groove 7 is 60 mm. The included angle between the long side of the glass placement table 5 and the long side of the fixture plate 1 is 45°. The overall length of the fixture plate 1 is 1070 mm, the width is 370 mm, the position of the groove center point 8 is 185 mm away from each upper and lower edge, the glass placement table 5 is 250 mm long and 186 mm wide. The fixture plate 1 has been designed and manufactured more precisely to ensure the stability of the two pieces of glass during the printing process. It can be adjusted according to the specific size of the glass, improving the versatility of the fixture. In this embodiment, the shape and size of the groove of the fixture will be more precise, which can better fix the glass and prevent the glass from moving or shaking during the printing process, thus ensuring the accuracy and clarity of the printed pattern. Printing two pieces of glass at the same time can enable the two pieces of glass to be screen-printed under the same process conditions, reducing the differences caused by printing in different batches, which helps to improve the consistency of the product and ensure the stability of the printing quality.

[0034] Working principle:

[0035] Place the fixture plate 1 on a stable workbench to ensure that the fixture plate 1 is in a horizontal state. Carefully place the curved glass on the glass placement table 5, and use the glass limiting edge 4 to prevent the glass from moving in the groove. The position of the glass should be aligned with the groove center point 8 as much as possible to ensure the accuracy of printing.

[0036] Turn on the vacuum adsorption device. Generate negative pressure through several vacuum adsorption holes 6 on the glass placement table 5 to firmly adsorb the glass on the glass placement table 5, reducing the movement of the glass during the printing process.

[0037] The operator uses the screen printing equipment to print the ink on the curved glass according to a predetermined pattern. During the printing process, the concave arc surface design of the diversion groove 3 can guide the flow of the ink, making the ink more evenly distributed on the glass surface. The secondary groove 7 can enhance the adsorption force between the glass and the groove, further stabilizing the glass.

[0038] After printing is completed, turn off the vacuum adsorption device, and carefully remove the printed glass from the glass placement table 5 for subsequent processing or inspection.

[0039] The above-described embodiments merely represent certain implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
