By integrating the advantages of various materials, such as high hardness, strong durability, high precision, corrosion resistance, etc., it can meet different complex production requirements. Compared with the steel mesh of a single material, the composite screen printing stencil steel mesh is more comprehensive and superior in performance.

[0003] In the electronic manufacturing industry, the steel mesh is an important tool for accurately printing materials such as solder paste and glue onto substrates such as circuit boards.

When printing and processing circuit boards of different sizes are required, it helps to assemble and install the connection frame 12 and the composite screen printing stencil 13 of the appropriate size according to the size of the circuit board.

[0033] Among them, the moving plates 6 are all in a horizontal state. At the middle of both ends of the surface of the moving plates 6, clamping blocks 8 are fixed. At the middle of the inner surfaces on both sides of the installation frame 1, clamping grooves 9 matching the clamping blocks 8 are correspondingly opened. The clamping grooves 9 are all in a horizontal state. The clamping blocks 8 help to limit the moving plates 6 and facilitate the stable movement of the moving plates 6; the clamping blocks 8 are all located in the corresponding clamping grooves 9 on the installation frame 1, and the clamping blocks 8 and the corresponding clamping grooves 9 on the installation frame 1 are slidably connected along the horizontal direction. The clamping grooves 9 on the installation frame 1 help to limit the clamping blocks 8 and facilitate the stable movement of the clamping blocks 8.

[0034] On one end surface of the screw rod 4 close to the moving plate 6, a rotating rod 7 is fixedly installed. The rotating rods 7 penetrate through both side surfaces of the middle part of the corresponding moving plate 6. The outer ring surfaces of the rotating rods 7 are rotationally connected to the middle parts of the corresponding moving plates 6 through bearings. The rotating rods 7 facilitate the rotation and limit of the screw rod 4, which is beneficial to the use of the screw rod 4. The rotating rods 7 are all in a horizontal state. On one end surface of the screw rod 4 far from the rotating rod 7, a rotating block 14 is fixedly installed. The rotating block 14 helps to rotate the screw rod 4, which is convenient for the use of the screw rod 4. In the middle of both ends of the side surfaces of the moving plates 6 away from each other, a limiting rod 5 is fixedly installed. The limiting rods 5 are all in a horizontal state. The limiting rods 5 penetrate through the inner surface and the outer surface of the corresponding position on the mounting frame 1. The limiting rods 5 can limit the moving plates 6, which is convenient for stably moving the moving plates 6.

[0035] On the mounting frame 1, limiting holes 15 are opened corresponding to the limiting rods 5. The limiting holes 15 penetrate through the inner surface and the outer surface of the corresponding position on the mounting frame 1. The inner ring surfaces of the limiting holes 15 on the mounting frame 1 are in a state of being matched and fitted with the outer ring surfaces of the corresponding limiting rods 5. The limiting holes 15 on the mounting frame 1 help to limit the limiting rods 5. In the middle of both ends of the two side surfaces of the mounting frame 1, mounting plates 2 are fixedly installed. In the middle of the mounting plates 2, bolts 3 are threadedly inserted along the vertical direction. The bolts 3 are all in a vertical state and penetrate through the upper surface and the lower surface of the middle part of the corresponding mounting plates 2. The bolts 3 can install and limit the mounting plates 2, which is convenient for stably using the mounting plates 2.

[0036] The working principle of the present utility model is as follows: During the use process, the mounting plates 2 are corresponded to the corresponding positions on the external printing equipment for the circuit board. Further, the mounting plates 2 and the corresponding positions on the external printing equipment for the circuit board are installed through the bolts 3. The bolts 3 can fix and limit the mounting plates 2, which is beneficial to stably using the mounting plates 2. The mounting plates 2 can support and limit the mounting frame 1 and various components assembled on the mounting frame 1, which is convenient for stably using the mounting frame 1 and various components assembled on the mounting frame 1. The mounting frame 1 can limit the moving plates 6 through the screw rod 4, the rotating rod 7, the limiting holes 15 and the limiting rods 5. The moving plates 6 can limit the connecting frame 12 through the limiting grooves 11 and the limiting blocks 10, which is beneficial to stably using the connecting frame 12. The connecting frame 12 can fix and limit the composite stencil steel mesh 13, which is convenient for stably using the composite stencil steel mesh 13.

[0037] The device installed on the external phase for printing the circuit board can print materials such as solder paste and glue onto the circuit board through the composite stencil 13 inside the connection frame 12 to perform printing processing on the circuit board. When processing circuit boards of different sizes, it is necessary to replace the composite stencils 13 of different sizes according to the size of the circuit board. Further, rotate the rotating block 14. When the rotating block 14 rotates, it can drive the screw rod 4 to rotate. When the screw rod 4 rotates, it will move in the direction away from each other along the threaded connection position on the mounting frame 1. When the screw rod 4 moves, it can drive the moving plate 6 to move away from the connection frame 12 through the rotating rod 7. When the moving plate 6 moves horizontally, it can drive the limiting rod 5 to move in the limiting hole 15 on the mounting frame 1. The mounting frame 1 can limit the moving plate 6 through the limiting hole 15 and the limiting rod 5. When the moving plate 6 moves, it can drive the clamping block 8 to move horizontally in the clamping groove 9 on the mounting frame 1. The mounting frame 1 can limit the moving plate 6 through the clamping groove 9 and the clamping block 8, which is convenient for stably moving the moving plate 6.

[0038] After moving the moving plate 6 in the direction away from each other, the limiting groove 11 on the moving plate 6 will be separated from the limiting block 10 on the connection frame 12 to cancel the limitation of the connection frame 12. Further, remove the connection frame 12 and the composite stencil 13 to disassemble the connection frame 12 and the composite stencil 13. Further, reset the connection frame 12 and the composite stencil 13 suitable for the size of the circuit board between the moving plates 6, and rotate the rotating block 14 and the screw rod 4 so that the moving plate 6 moves towards the connection frame 12, and the limiting groove 11 on the moving plate 6 moves to correspond to the limiting block 10 on the connection frame 12. The moving plate 6 can fix and limit the connection frame 12 and the composite stencil 13 through the limiting groove 11 and the limiting block 10 to complete the assembly of the connection frame 12 and the composite stencil 13, which is convenient for using the connection frame 12 and the composite stencil 13.

[0039] During the use process, it helps to adjust the distance between the moving plates 6 inside the mounting frame 1 for composite stencils 13 of different sizes, so as to ensure the applicable range of the mounting frame 1 and the moving plates 6 inside the mounting frame 1. When it is necessary to perform printing processing on circuit boards of different sizes, it helps to assemble and install the connection frame 12 and the composite stencil 13 of appropriate sizes according to the size of the circuit board.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
