Description

Technical Field

[0001] This utility model belongs to the technical field of circuit board processing equipment, specifically relating to a circuit board hole plugging machine table. Background Technology

[0002] The via plugging process is a crucial step in the PCB manufacturing process, playing a decisive role in the quality and performance of the PCB. The quality of via plugging directly affects the stability of the electrical connections, insulation performance, and overall reliability of the PCB, thus impacting the lifespan and operational efficiency of electronic products.

[0003] Currently, traditional circuit board via-filling machines mostly use relatively simple fixing methods, which are difficult to accurately and stably position circuit boards of different shapes and sizes. During the via-filling process, displacement is prone to occur due to insecure fixing. Once this displacement occurs, the via position will be deviated, resulting in a mismatch between the via and the circuit board, which will greatly affect the via-filling quality and may even cause serious problems such as short circuits or open circuits on the circuit board, rendering the entire circuit board unusable. Utility Model Content

[0004] The purpose of this utility model is to provide a circuit board hole plugging machine table to solve the problem mentioned in the background art that traditional circuit board hole plugging machines mostly use relatively simple fixing methods, which are difficult to accurately and stably position circuit boards of different shapes and sizes, and are prone to displacement during the hole plugging process due to insecure fixing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circuit board hole plugging machine table, comprising a table body and two positioning frames movably connected to the surface of the table body. The surface of each positioning frame has a moving groove, and a connecting rod is movably connected within the moving groove. A pressure plate and an adjusting block are fixed to both ends of the connecting rod, respectively. Two limiting grooves are symmetrically opened on the surface of the table body, and a limiting rod, fixedly connected to the positioning frame, is movably connected within the limiting groove. A limiting block is fixed to the bottom of the limiting rod, and a support spring for supporting the limiting block is sleeved on the outside of the limiting rod. A scraper is movably connected to the surface of the table body.

[0006] In a further embodiment, a positioning ring is fixed to one outer wall of the tabletop body, and a handle is rotatably connected inside the positioning ring.

[0007] In a further embodiment, one end of the handle is fixed with a rotating shaft extending into the main body of the table, and the outer wall of the rotating shaft is fixed with two cams for pushing the limiting block.

[0008] In a further embodiment, a through groove is provided on one outer wall of the tabletop body, and a collection box is movably connected in the through groove of the tabletop body, and a discharge groove is provided on the surface of the tabletop body.

[0009] In a further embodiment, two dovetail grooves are symmetrically formed on the surface of the main body of the table, and a dovetail slider that is fixedly connected to the scraper is slidably connected in the dovetail groove of the main body of the table.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] The table of this circuit board plugging machine can adjust the position of the pressure plate by adjusting the position of the connecting rod in the positioning frame. According to the size of the circuit board, the distance between the two pressure plates can be adjusted. At the same time, the support spring supports the limit block, so that the two pressure plates are pressed against the surface of the circuit board. It can quickly position and fix circuit boards of different sizes and prevent the circuit board from shifting during the plugging process.

[0012] The scraper quickly removes residual adhesive and waste from the worktable, ensuring its cleanliness and preventing it from entering the processing area.

[0019] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0020] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0021] This utility model provides, for example Figure 1-4 The circuit board hole plugging machine table shown includes a table body 1 and two positioning frames 2 movably connected to the surface of the table body 1. The surface of the positioning frame 2 is provided with a moving groove, and a connecting rod 3 is movably connected in the moving groove of the surface of the positioning frame 2. The connecting rod 3 is a cuboid structure, and a pressure plate 4 and an adjusting block 5 are welded to both ends of the connecting rod 3 respectively. The surface of the adjusting block 5 is provided with a threaded hole, and a fixing bolt is threaded into the threaded hole of the surface of the adjusting block 5. The surface of the positioning frame 2 is provided with a plurality of fixing screw holes that match the fixing bolts. By screwing the fixing bolts into the fixing screw holes on the surface of the positioning frame 2, the positions of the adjusting block 5 and the pressure plate 4 can be fixed.

[0022] Two limiting grooves are symmetrically opened on the surface of the table body 1, and a limiting rod 6 is movably connected to the limiting groove on the surface of the table body 1 and fixedly connected to the positioning frame 2. The limiting rod 6 is a cuboid structure, which can restrict the movement path of the positioning frame 2 and prevent the positioning frame 2 from rotating on the surface of the table body 1. The bottom of the limiting rod 6 is fixed with a limiting block 7 by screws. A support spring 8 for supporting the limiting block 7 is sleeved on the outside of the limiting rod 6. By adjusting the position of the connecting rod 3 in the positioning frame 2, the position of the pressure plate 4 is adjusted. According to the size of the circuit board, the distance between the two pressure plates 4 is adjusted. At the same time, the support spring 8 supports the limiting block 7, so that the two pressure plates 4 are pressed against the surface of the circuit board. This can quickly position and fix circuit boards of different sizes and prevent the circuit board from shifting during the process of plugging holes.

[0023] A positioning ring 9 is welded to one outer wall of the tabletop body 1. A handle 10 is rotatably connected inside the positioning ring 9. The surface of the positioning ring 9 is also provided with a threaded hole, and a positioning bolt is threaded into the threaded hole on the surface of the positioning ring 9. Tightening the positioning bolt makes it fit against the surface of the handle 10, which can fix the position of the handle 10. A rotating shaft 11 extending into the tabletop body 1 is welded to one end of the handle 10. The rotating shaft 11 is rotatably connected to the tabletop body 1 through a welded bearing. Two cams 12 for pushing the limit block 7 are welded to the outer wall of the rotating shaft 11. By driving the cams 12 to rotate through the handle 10, the limit block 7 and the limit rod 6 can be pushed upward, thereby pushing the positioning frame 2 and the pressure plate 4 away from the tabletop body 1, making it convenient to place the circuit board at the bottom of the pressure plate 4.

[0024] A scraper 13 is movably connected to the surface of the table body 1. A through groove is opened on one outer wall of the table body 1, and a collection box 14 is movably connected in the through groove of the table body 1. A discharge groove is opened on the surface of the table body 1. Two dovetail slides are symmetrically opened on the surface of the table body 1, and a dovetail slider fixedly connected to the scraper 13 is slidably connected in the dovetail slide of the table body 1. The dovetail slider can restrict the movement path of the scraper 13 and prevent the scraper 13 from separating from the table body 1. By moving the scraper 13, residual glue and waste on the table body 1 can be quickly cleaned, ensuring the cleanliness of the table body 1 and preventing residual glue and waste from mixing into the processing area, interfering with the normal contact between the circuit board and the hole plugging equipment, thereby reducing the processing accuracy and affecting the hole plugging effect. At the same time, in conjunction with the collection box 14, residual glue and waste can be collected for convenient centralized processing.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0026] In the description of this utility model, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Working principle:

[0028] When using the circuit board plugging machine table, adjust the position of the connecting rod 3 within the positioning frame 2 to adjust the position of the pressure plate 4. Adjust the distance between the two pressure plates 4 according to the size of the circuit board. Drive the rotating shaft 11 and cam 12 to rotate via the handle 10. The cam 12 pushes the limit block 7 and limit rod 6 upward, thereby pushing the positioning frame 2 and pressure plate 4 away from the table body 1. Place the circuit board at the bottom of the pressure plate 4. Then rotate the handle 10 to release the cam 12 from supporting the limit block 7. The support spring 8 supports the limit block 7, so that the two pressure plates 4 are pressed against the surface of the circuit board, quickly positioning and fixing the circuit board. When there is residual glue and waste on the surface of the table body 1, move the scraper 13 to quickly clean the residual glue and waste on the table body 1, ensuring the cleanliness of the table body 1. The residual glue and waste fall into the collection box 14 through the discharge chute.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
