Description

Technical Field

[0001] The utility model relates to the technical field of through-hole screen printing fixtures, in particular to a through-hole screen printing fixture that does not require precise positioning. Background Art

[0002] When screen printing is performed on some printed parts with through holes, it is usually necessary to produce a workpiece printing pattern on the mesh and cover the through hole parts that do not need to be printed to prevent the paint from flowing into the through hole.

[0003] For example, Chinese patent CN215551785U discloses a screen printing fixture, which includes a base plate and a fixed frame. The fixed frame and the base plate are provided with corresponding through grooves, and an adhesive layer is provided between the fixed frame and the base plate. During printing, the printed part is fixed by the fixed frame and the adhesive layer to prevent the processed part from shifting during printing.

[0004] However, in order to ensure printing quality, through holes of different sizes need to produce corresponding printing patterns on the mesh during printing, and a precise positioning fixture is required to accurately align the through holes on the printed part with the blocked parts, which is cumbersome and affects printing efficiency.

[0005] Based on this, the utility model designs a through-hole screen printing fixture that does not require precise positioning to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a through-hole screen printing fixture that does not require precise positioning.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A through-hole screen printing fixture that does not require precise positioning includes a substrate, a carrier plate, and a plurality of mounting blocks;

[0009] An air supply assembly connected to the air bin is installed inside the substrate, and a plurality of air inlet pipes are evenly and evenly fixedly installed on the top of the substrate at equal intervals; the air inlet pipes are connected to the air supply assembly;

[0010] The bottom of the carrier plate is evenly and evenly provided with docking grooves for accommodating the air intake pipe, and the top of the carrier plate is evenly and evenly provided with mounting grooves for installing the mounting block, and the mounting block is plugged into the mounting grooves; a bottom groove is provided in the middle of the lower side of the mounting block, and two through-going air holes are provided on the upper side of the mounting block; the air holes are connected with the air intake pipe through the bottom groove, the docking groove and the air intake pipe.

[0011] Furthermore, the two air holes are symmetrically distributed on the mounting block.

[0012] Furthermore, the base plate is composed of a lower plate and an upper plate, an air supply assembly is installed on the lower plate, and an air intake pipe is fixedly installed on the top of the upper plate.

[0013] Furthermore, the air supply assembly includes an air inlet and an air flow groove, the air inlet is opened in the middle of the lower plate, and the air flow groove connected with the air inlet is opened on the upper side of the lower plate.

[0014] Furthermore, the airflow groove is composed of a transverse groove and a longitudinal groove. A transverse groove connected to the air inlet is opened in the middle of the upper side of the lower plate, and a plurality of longitudinal grooves are opened at equal intervals on the upper side of the lower plate, and the longitudinal grooves are all connected to the transverse groove.

[0015] Furthermore, the air inlet pipe on the upper plate is located on the upper side of the longitudinal groove on the lower plate.

[0016] Furthermore, the height of the mounting block is greater than the depth of the mounting groove.

[0017] Furthermore, buckles are symmetrically provided on both sides of the carrier plate.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The workpiece to be printed with through holes is placed on the mounting block and pressed tightly, so that the through holes on the printed workpiece are roughly aligned with the air holes on the mounting block. During this process, the air holes on the mounting block do not need to be consistent in size with the through holes on the printed workpiece, nor do they need to be completely aligned, thereby making the placement of the printed workpiece more convenient; during printing, if the through holes on the printed workpiece need to be coated, air is sucked through the air supply component, thereby driving the air flow outside the through holes of the printed workpiece to flow into the through holes through the air holes, bottom grooves, docking grooves and air inlet pipes on the mounting block, thereby driving the paint on the outside of the printed workpiece to flow into the through holes, and coating the through holes; if the through holes on the printed workpiece do not need to be printed, air is discharged through the air supply component, thereby driving the air flow to flow outside the through holes of the printed workpiece through the air holes, bottom grooves, docking grooves and air inlet pipes on the mounting block, thereby preventing the paint from flowing into the through holes; after printing is completed, air is blown through the air supply component to prevent the paint from flowing into the air holes and causing blockage; thus, there is no need to make graphics on the mesh cloth and there is no need to accurately clamp the printed workpiece, thereby improving printing efficiency.

[0034] The two air holes 51 are symmetrically distributed on the mounting block 5 .

[0035] In this embodiment, when the through-hole screen printing fixture that does not require precise positioning works normally, the workpiece to be printed with the through-hole is placed on the mounting block 5 and pressed tightly, so that the through-hole on the printed workpiece is roughly aligned with the air hole 51 on the mounting block 5. In this process, the air hole 51 on the mounting block 5 does not need to be consistent in size with the through-hole on the printed workpiece, nor does it need to be completely aligned, so that the placement of the printed workpiece is more convenient; when printing, if the through-hole on the printed workpiece needs to be coated, air is sucked through the air supply component 2, so that air is brought in through the air hole 51 on the mounting block 5, the bottom groove 52, the docking groove 42 and the air inlet pipe 3 The airflow on the outside of the through hole of the dynamic printing piece flows into the through hole, thereby driving the paint on the outside of the printed piece to flow into the through hole, and coating the through hole; if the through hole on the printed piece does not need to be printed, the air is discharged through the air supply component 2, thereby driving the airflow to flow outside the through hole of the printed piece through the air hole 51, the bottom groove 52, the docking groove 42 and the air inlet pipe 3 on the mounting block 5, thereby preventing the paint from flowing into the through hole; after printing is completed, air is blown through the air supply component 2 to prevent the paint from flowing into the air hole 51 and causing blockage; thus, there is no need to make graphics on the mesh and there is no need to accurately clamp the printed piece, thereby improving printing efficiency.
