Description

Technical Field

[0001] This utility model relates to the field of circuit board screen printing technology, and in particular to a circuit board screen printing device for rapid positioning. Background Technology

[0002] The electronic devices we use every day are all composed of circuit control and circuit boards. After the circuit board is processed and formed, the electronic device information on the surface of the circuit board needs to be marked. Therefore, the circuit board needs to be screen printed and laser engraved.

[0003] Existing circuit board screen printing devices typically employ a single-board processing mode. After processing each circuit board, the locking mechanism must be released, the completed circuit board removed, the circuit board to be processed placed in, and the locking mechanism re-engaged before processing the next circuit board can begin. This process is cumbersome, time-consuming, and labor-intensive, reducing overall production efficiency. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, this utility model provides a circuit board screen printing device for rapid positioning.

[0005] An embodiment of this utility model provides a rapid positioning circuit board screen printing device, comprising: A base plate is provided with an electric slide rail, and a movable stage is fixedly provided on the slide block of the electric slide rail. Two clamping components are provided at both ends of the movable stage. The clamping assembly includes a lifting plate, two guide rods, two springs, an adjusting plate, a pressure plate, an L-shaped frame, and rollers. The guide rods are all fixedly mounted on the moving platform, and each guide rod has a limit block fixedly mounted on its top. The guide rods slide through the lifting plate. The springs are all fixedly mounted on the moving platform, and the other end of each spring is fixedly mounted on the bottom of the lifting plate. The adjusting plate is mounted on the lifting plate, and the pressure plate is fixedly mounted on the bottom of the adjusting plate. The L-shaped frame is fixedly mounted on the base plate, and the rollers are fixedly mounted on the L-shaped frame.

[0006] Furthermore, two limiting components are provided at both ends of the moving platform. Each limiting component includes a limiting plate, a fixing block, and a screw. One end of the screw is rotatably connected to one side of the limiting plate. The fixing block is fixedly mounted on the moving platform, and the screw passes through the fixing block and is threadedly connected to it.

[0007] Furthermore, a sliding hole is provided through the lifting plate, the adjusting plate is slidably disposed through the sliding hole, a threaded hole is provided through the top of the sliding hole, and a bolt is threadedly connected to the threaded hole.

[0008] Furthermore, both ends of the mobile platform are provided with placement slots, and protective pads are laid in the placement slots.

[0009] Furthermore, a rubber pad is fixedly provided at the bottom of the pressure plate, and the rubber pad is used to press against the circuit board.

[0010] Furthermore, a bracket is fixedly provided at the bottom of the base plate, and the bracket is used to support the base plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. A clamping assembly is installed. During the processing of the circuit board, the rollers can press the lifting plate downwards, which in turn can drive the pressure plate to move down and hold the circuit board firmly. At the same time, as the circuit board on the other side moves towards the center, the pressure plate can be lifted and reset by the action of the spring. Then the circuit board can be removed and the next circuit board to be processed can be placed. This process is repeated, saving waiting time and eliminating the need for manual clamping and unclamping of the circuit boards, which significantly improves work efficiency.

[0012] 2. An adjustment plate and bolts are provided. By loosening the bolts, the position of the pressure plate can be adjusted via the adjustment plate to accommodate circuit boards of different specifications, thus enhancing adaptability.

[0013] In summary, this utility model is equipped with a clamping assembly, enabling two workstations to process circuit boards in a cyclical manner and automatically clamping the circuit boards, thereby improving work efficiency and practicality. It also includes an adjustment plate and bolts to accommodate circuit boards of different specifications, enhancing its adaptability. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a rapid positioning circuit board screen printing device, comprising: The base plate 1 has screen printing devices installed at both ends. These devices utilize existing, mature technology for screen printing on circuit boards, and will not be described in detail here. A bracket 17 is fixedly installed at the bottom of the base plate 1 to support it. An electric slide rail 2 is mounted on the base plate 1, and a moving platform 3 is fixedly mounted on the slide block of the electric slide rail 2, allowing the electric slide rail 2 to move the moving platform 3 back and forth. Both ends of the moving platform 3 have placement grooves 14, and protective pads are placed inside the placement grooves 14 to protect the circuit boards.

[0020] Two clamping assemblies are provided at both ends of the moving platform 3. The clamping assemblies include a lifting plate 4, two guide rods 5, two springs 6, an adjusting plate 8, and a pressure plate 9. The guide rods 5 are all fixedly installed on the moving platform 3. A limit block is fixedly installed on the top of each guide rod 5. The guide rods 5 slide through the lifting plate 4. The guide rods 5 play a guiding and supporting role for the lifting plate 4.

[0021] Springs 6 are all fixedly mounted on the moving platform 3, and the other end of each spring 6 is fixedly mounted on the bottom of the lifting plate 4, so that the lifting plate 4 can be elastically connected to the moving platform 3 through the springs 6. An adjusting plate 8 is mounted on the lifting plate 4, and a pressure plate 9 is fixedly mounted on the bottom of the adjusting plate 8. A rubber pad 10 is fixedly mounted on the bottom of the pressure plate 9, and the rubber pad 10 is used to press against the circuit board.

[0022] The L-shaped frame 15 is fixedly mounted on the base plate 1, and the roller 16 is fixedly mounted on the L-shaped frame 15. The roller 16 is configured to cooperate with the lifting plate 4 so that when the lifting plate 4 moves to the roller 16, the roller 16 can push it downward.

[0023] A sliding hole 7 is provided through the lifting plate 4, and an adjusting plate 8 is slidably provided through the sliding hole 7, so that the adjusting plate 8 can slide within the sliding hole 7. A threaded hole is provided through the top of the sliding hole 7, and a bolt 11 is threadedly connected inside the threaded hole. The bolt 11 is abutted against the adjusting plate 8, so that the bolt 11 can tighten and fix the adjusting plate 8.

[0024] Two limiting components are provided at both ends of the moving platform 3. The limiting components include a limiting plate 12, a fixing block and a screw 13. One end of the screw 13 is rotatably connected to one side of the limiting plate 12. The fixing block is fixedly installed on the moving platform 3. The screw 13 passes through the fixing block and is threadedly connected to it, so that rotating the screw 13 can drive the limiting plate 12 to move.

[0025] The detailed working process of this utility model is as follows: 1. During processing, the circuit board to be processed is placed in the placement slot 14 in the middle and limited by the limiting plate 12. Then, the moving table 3 is moved to one side by the electric slide rail 2, which in turn moves the circuit board to be processed to the outside to the screen printing device on the same side for screen printing. At the same time, the roller 16 on this side pushes the corresponding lifting plate 4 downward and compresses the spring 6. The lifting plate 4 drives the pressure plate 9 to move downward through the adjusting plate 8, so that the circuit board can be pressed tightly by the rubber pad 10. 2. Simultaneously, the moving table 3 will move the processed circuit board on the other side towards the center, causing the roller 16 on that side to separate from the corresponding lifting plate 4. This allows the lifting plate 4 and pressure plate 9 to be lifted and reset under the action of the spring 6, after which the circuit board can be removed and the next circuit board to be processed can be placed. This process is repeated, saving waiting time and eliminating the need for manual clamping of the circuit boards, thus improving work efficiency.

[0026] 3. During adjustment, loosen bolt 11 to separate it from adjusting plate 8. Then, the position of pressure plate 9 can be adjusted by moving adjusting plate 8. Finally, tighten bolt 11 to fix adjusting plate 8 and pressure plate 9 together. This allows it to adapt to circuit boards of different specifications, enhancing its adaptability.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
