Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a device for treating the inner wall of a circuit board hole. Background Technology

[0002] After circuit boards are routerd, a significant amount of residual adhesive remains inside the holes. Some of this adhesive can be removed using a plasma adhesive remover, while others, due to their strong adhesion, cannot be removed and require manual removal. Currently, during this process, operators place the circuit board on a platform and use a scraper to remove the adhesive. However, because the scraper's length is parallel to the hole's axis, it often causes unnecessary scratches to the holes. If there is circuitry at the hole location, this can affect the circuitry. Utility Model Content

[0003] This utility model provides a device for treating the inner wall of a circuit board hole, which solves the shortcomings of the prior art and addresses the problem of damage to the hole caused by the inconvenience of maintaining the correct posture when scraping with a scraper. It has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A circuit board hole inner wall treatment device includes a base plate, an upper extension post mounted on the base plate by screws, a through post at the upper end of the upper extension post, a rotating horizontal plate rotatably mounted on the through post, an oblong hole on the rotating horizontal plate, a sliding sleeve fitted on the rotating horizontal plate, an outer sleeve passing through the sliding sleeve, the outer sleeve passing through the oblong hole, an outer flange at the lower end of the outer sleeve, the outer flange being located below the sliding sleeve, a limit nut connected to the upper end of the outer sleeve by threads, a spring fitted on the outer sleeve, the spring being located between the limit nut and the sliding sleeve, an inner rod passing through the outer sleeve, a connector at the lower end of the inner rod, a blade at the lower end of the connector, a scraper formed on the outer periphery of the lower end of the blade, the connector being located at the lower end of the outer flange, and a rotating handle at the upper end of the inner rod.

[0006] The rotating horizontal plate allows the tool holder and other components to be moved to appropriate positions as needed, and the tool holder can also move on the rotating horizontal plate, thereby improving the flexibility of tool holder and other component position adjustment. Furthermore, components such as sliding sleeves ensure that the axial direction of the tool holder and other components coincides with the axial direction of the hole to be processed on the circuit board, preventing unnecessary damage to the hole during processing. In addition, the inclusion of multiple scraping blades improves the efficiency of the adhesive removal operation.

[0007] Furthermore, to prevent the circuit board from rotating with the tool holder during processing, four L-shaped plates are provided above the base plate. A pair of connecting rods are inserted through the L-shaped plates. The upper end of the connecting rod is connected to an upper cap by a thread. The upper cap is located on the upper side of the L-shaped plate. The lower end of the connecting rod is provided with a limiting plate. The limiting plate is located on the lower side of the base plate. Four pairs of strip holes are opened on the base plate, and the connecting rods are inserted into the strip holes.

[0008] Furthermore, in order to avoid affecting the movement of the L-shaped plate, multiple pads are installed on the lower wall of the base plate.

[0009] Furthermore, in order to facilitate the quick implementation of the circuit board's positioning operation, a rotating shaft is provided on the base plate. A rotating block is welded to the upper end of the rotating shaft. An inner top screw is connected to the rotating block by a thread. A rotating end cap is provided on the outer end of the inner top screw, and an inner top rod is formed on the inner end of the inner top screw. The inner end of the inner top rod acts on the outer wall of the L-shaped plate.

[0010] Furthermore, in order to lock the rotation of the inner lead screw and ensure the locking effect, multiple limit pins are connected to the base plate, with the limit pins located on one side of the inner lead screw.

[0011] Furthermore, during the degumming operation, in order to prevent the rotating horizontal plate from rotating, a side column is connected to the upper end of the through column. A downward pressing plate is rotatably mounted on the side column, and a pressure plate is fitted on the side column. The lower wall of the pressure plate is tightly attached to the rotating horizontal plate, and the lower end of the downward pressing plate acts on the lower wall of the pressure plate, so that the lower wall of the pressure plate acts on the upper wall of the rotating horizontal plate. A holding vertical rod is welded to one end of the rotating horizontal plate.

[0012] The advantages of the above technical solution are:

[0013] This invention, when removing stubborn adhesive from the inner wall of a hole, uses a circuit board-limiting mechanism to quickly complete the adhesive removal operation. It also ensures the alignment of components such as the cutting tool with the hole's axial direction, thereby improving the cleaning speed and effectiveness of the adhesive removal, and significantly avoids scratching the inner wall of the hole.

[0022] In this embodiment, when scraping off stubborn adhesive residue from holes in a circuit board, the operator places the circuit board on the base plate 1, then rotates the rotating horizontal plate 35 and adjusts the position of the blade 41 on the rotating horizontal plate 35 so that the blade 41 is directly opposite the hole. Then, the operator presses down on the rotating handle 45 to compress the spring 43 and inserts the lower end of the blade 41 into the hole in the circuit board. The operator then rotates the blade 41 by rotating the handle 45, and the blade 41 scrapes off the adhesive residue from the inner wall of the hole through the scraping blade 42. After completion, the blade 41 moves upward under the action of the spring 43 and is removed from the hole.

[0023] In some embodiments, four L-shaped plates 21 are provided above the base plate 1. A pair of connecting rods 2 pass through the L-shaped plates 21. The upper end of the connecting rod 2 is threadedly connected to an upper cap 20, which is located on the upper side of the L-shaped plate 21.

Multiple limiting pins 26 are connected to the base plate 1, and the limiting pins 26 are located on one side of the inner top screw 24.

[0024] In this embodiment, when limiting the circuit board, the operator places the circuit board inside the L-shaped plate 21, and then rotates the inner top screw 24 around the pivot, so that the inner end of the inner top screw 24 acts on the L-shaped plate 21, thereby causing the L-shaped plate 21 to move inward and the inner wall of the L-shaped plate 21 to act on the four sides of the circuit board, thereby achieving the purpose of fixing the circuit board. If the fixing effect of the circuit board is not good, the inner top screw 24 can be turned to ensure the limiting effect of the L-shaped plate 21 on the four side walls of the circuit board.
