Abstract
The utility model relates to a be used for printing seal ring screen printing otter board of thickness adjustable, including screen frame, silk screen and template piece, screen frame and silk screen fixed connection, the template piece establish at the silk screen middle part, all the other regional adhesive tape that bond except the template piece on the silk screen is sealed. Compared with the prior art, the utility model has the advantages of simple process, with low costs, efficient, sealed and viscose glue thickness is adjustable.
Description
Technical Field
The utility model belongs to the technical field of bonding and seal ring preparation technique and specifically relates to a screen printing otter board that is used for thickness adjustable printing bonding and seal ring.
Background
In the prior art, CIPG (Cured-In-Place-Gasket) sealing gaskets are mostly used for printing the sealing gaskets, the CIPG is manufactured by adopting a mold for injection or a dispenser for dispensing, and both the glue injection process and the dispensing process need special equipment, so that the equipment cost is high, and the sealing gaskets introduced by the screen printing technology can be manufactured.
However, the existing screen printing technology has the following defects when being applied to the manufacture of bonding and sealing gaskets:
1. the common screen printing thickness is thin, and any required thickness dimension cannot be obtained;
2. the SMT metal mesh plate can obtain a certain thickness, but cannot obtain a continuous annular sealing pattern;
3. the thickness of the sealing gasket manufactured by the existing screen plate is not adjustable.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a screen printing otter board for printing bonding and seal ring that thickness is adjustable in order to overcome the defect that above-mentioned prior art exists.
The purpose of the utility model can be realized through the following technical scheme:
the screen printing screen plate for printing the sealing gaskets with adjustable thickness comprises a screen frame, a screen and a template sheet, wherein the screen frame is fixedly connected with the screen, the template sheet is arranged in the middle of the screen, and the other areas except the template sheet on the screen are bonded with adhesive tapes for sealing.
Preferably, the wire mesh is fixed in the mesh frame in a net stretching mode.
Preferably, the template sheet is bonded to the mesh.
Preferably, the template sheet is a metal template sheet.
Preferably, the formwork sheet comprises an inner formwork sheet and an outer formwork sheet; a through groove is arranged between the inner die plate piece and the outer die plate piece.
More preferably, said through slots are obtained by laser engraving.
More preferably, the shape of the through groove is the same as that of the sealing gasket.
More preferably, a bridge is arranged in the through groove, and two ends of the bridge are respectively connected with the inner die plate sheet and the outer die plate sheet.
Compared with the prior art, the utility model has the advantages of it is following:
the practical range is wide: the thickness of the silk-screen printing adhesive and the sealing gasket is adjustable, so that different design schemes can be met;
secondly, the consistency is good: aiming at the thick sealing gasket, the thickness of glue at the butt joint part in the traditional glue dispensing scheme is uneven, so that the stress of the galvanic pile press mounting is uneven, and the leakage risk exists;
thirdly, the cost is low: aiming at the thick sealing gasket, the equipment of the traditional scheme is expensive, and the cost of the screen printing screen plate is lower;
fourthly, the efficiency is high: to thick sealed the pad, the utility model provides a screen printing otter board technique can be fast large batch preparation seal ring, and efficiency is higher.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall fall within the protection scope of the present invention.
Example (b):
the utility model provides a be used for printing seal ring screen printing otter board of thickness adjustable, including screen frame 1, silk screen 2, template piece 3 and sticky tape 4, screen frame 1 and silk screen 2 are through the mode fixed connection that stretches tight, and template piece 3 bonds in the central zone of silk screen, and sticky tape 4 bonds in the area beyond template piece 3 on silk screen 2.
The silk screen 2 in the embodiment is made by using a 60-mesh silk screen with a wire diameter of 100 microns and performing screen stretching, as shown in fig. 1; the template sheet 3 is made of a stainless steel sheet with the thickness of 0.4mm, laser engraving is carried out by an engraving machine to form a required pattern template, as shown in figure 2, a certain connecting bridge frame 5 is reserved on the template sheet 3 during laser engraving, as shown in figure 3, the bridge frame 5 can ensure that the pattern of a sealing gasket in the template sheet 3 is not changed during installation, and further the size precision of the manufactured sealing gasket is ensured.
The specific manufacturing steps of the screen printing screen plate in the embodiment are as follows:
1. selecting a 60-mesh silk screen 2 with the wire diameter of 100 microns, and fixedly connecting the silk screen with a screen frame 1;
2. selecting a stainless steel sheet with the thickness of 0.4mm, processing the stainless steel sheet into a required pattern template by a carving machine, and reserving a certain connecting bridge frame 5;
3. bonding the template sheet 3 to the middle area of the screen plate by using bonding glue to ensure tight fit, as shown in FIG. 4;
4. using a glass adhesive tape with the thickness of 0.1 to shield the hollowed annular area in the silk screen, as shown in fig. 5;
