Description

Technical Field

[0001] The present application relates to the technical field of gasket production, and more specifically, to a silk screen relief printing device for sealing gaskets. Background Art

[0002] In screen printing, ink is poured at one end of a screen printing plate, and a squeegee applies a certain pressure to the ink area on the screen printing plate while moving uniformly towards the other end of the screen printing plate. The ink is extruded from the holes in the graphic part by the squeegee onto the substrate during the movement. Our company currently produces a small sealing gasket (as shown in Figure 4 ), and its production process includes silk-screen printing a sealing silicone rubber line on the surface of the gasket. In traditional printing processes, when the ink viscosity is low, the requirements for fixing the substrate are relatively low. However, the "ink" used for silk-screen printing of this type of sealing gasket is liquid silicone rubber with high viscosity, and the gasket product is relatively small, so it is difficult to position the bearing object.

[0003] If relying on the traditional platform vacuum adsorption method for positioning, since the product structure is small and the adsorption area is small, it is very difficult for the vacuum pump to adsorb the product. The adsorption force is much smaller than the silicone viscosity, resulting in adhesion and inability to print.

[0004] If using the method of pre-printing multiple cavities of small products and then stamping in the subsequent process, although the adsorption area is increased, the subsequent stamping positioning is more difficult and prone to product defects.

[0005] In addition, traditional hole positioning, side positioning and other methods have also been used in production. However, due to the small product structure, it is very difficult to fix the product by its own clamping force. If using the method of colloidal adhesion, the product is firmly adhered, but it is very inconvenient to pick up. Utility Model Content

[0013] Furthermore, limiting convex strips and limiting grooves that match each other are respectively provided at the edges of the opposite surfaces of the silk screen printing plate and the bottom platform.

[0029] Embodiment 1:

[0030] The following further details this application in conjunction with the accompanying drawings.

[0031] The embodiment of the present application discloses a silk screen relief plate device for a sealing gasket, including a base table 1 and a silk screen printing plate 2. One side of the silk screen printing plate 2 is hinged to the base table 1. A positioning support plate 3 is fixedly connected to the top surface of the base table 1. A number of positioning bumps 4 are fixedly connected in an array on the top surface of the positioning support plate 3. The size of the positioning bumps 4 is slightly larger than the inner hole size of the gasket product 13, so that the inner hole of the gasket product 13 can be in transitional fit with it. The positioning support plate 3 is provided with a taking cavity 5 at the edge of each positioning bump 4.

[0032] Please refer to FIGS. 1-3. Vacuum suction holes 6 are provided at the edges of the positioning support plate 3 where the positioning bumps 4 are located. An air channel 7 is provided on the base table 1 at the position corresponding to the vacuum suction holes 6. An air pipe interface 8 communicating with the air channel 7 is provided on one side of the base table 1 for connecting a vacuum pump, which can further improve the adsorption force on the gasket product 13. Preferably, the positioning support plate 3 and the base table 1 are connected by countersunk head screws. Sealing rubber strips 9 are provided along the edge of the air channel 7 between the bottom surface of the positioning support plate 3 and the base table 1, which is convenient for the disassembly of the positioning support plate 3 and improves the airtightness at the edge of the air channel 7.

[0033] Please refer to Figure 1-2 , limiting convex strips 10 and limiting grooves 11 are respectively provided at the edges of the opposite surfaces of the silk screen printing plate 2 and the base table 1. The limiting convex strips 10 and the limiting grooves 11 can be mutually engaged, which can effectively prevent the silk screen printing plate 2 and the base table 1 from shifting, thereby improving the silk screen printing accuracy. Preferably, a handle 12 is fixedly connected to the edge of the silk screen printing plate 2, which is convenient for the opening and closing of the silk screen printing plate 2.

[0034] The implementation principle of a silk screen relief plate device for a sealing gasket in the embodiment of the present application is as follows: In the present application, through the positioning bumps 4 fixedly connected to the positioning support plate 3, the gasket product 13 can be nested on the positioning bumps 4 to make it in a tight fit state. At the same time, through the setting of the vacuum suction holes 6, when in use, the air pipe interface 8 is connected to an external vacuum pump, which further improves the adsorption force of the positioning support plate 3 on the gasket product 13 and can effectively prevent the gasket from adhering to the silk screen printing plate 2 during silk screen printing. By providing a taking cavity 5 at the edge of the positioning bump 4, it is convenient to take the gasket product 13 after silk screen printing, solving the problems of difficult positioning and fixing and difficult manual taking for thin, soft, and small products during silk screen printing. On the other hand, since this method directly performs silk screen printing on the gasket product 13 after punching, in actual production, small scraps can be used to first process the gasket product 13 and then perform silk screen printing, improving the material utilization rate and reducing the generation of waste edge materials.

[0035] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
