Description

Technical Field

[0001] The utility model relates to the technical field of electronic circuit processing, in particular to a surface processing device for a metal bracket of an electronic circuit board. Background Art

[0002] Electronic circuit boards are also generally called circuit boards. When installing circuit boards, they need to be installed using brackets to form a stable support for the circuit boards, thereby improving the stability of the circuit boards during use. In order to improve the stability of the circuit boards, circuit board brackets generally use metal brackets. Metal brackets have the advantages of good toughness, good heat resistance and high strength.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN215036203U discloses a surface treatment device for a metal bracket of an electronic circuit board, including a frame, a same mounting plate fixedly mounted on the inner walls on both sides of the frame, an electric slide rail is arranged on the mounting plate, a movable plate is fixedly mounted on the electric slide rail, the movable plate is slidably connected with the mounting plate, a box is fixedly mounted on the bottom side of the movable plate, a servo motor is fixedly mounted on the top inner wall of the box, an active bevel gear is fixedly sleeved on the output shaft of the servo motor, two rotating shafts are rotatably mounted on the inner wall of the box, and the two rotating shafts are arranged in parallel. The utility model has a reasonable design, can quickly cut and grind the metal bracket blank, and can adjust the angle of the metal bracket blank as needed, thereby effectively improving the processing efficiency, and is simple to operate and convenient to use.

[0004] Metal brackets are generally hollow tubes, and burrs may remain on the surface during the production process. Since the surface of the circuit board contains a large number of electronic components, the burrs on the surface of the metal bracket may fall off to the surface of the circuit board, causing a short circuit in the circuit board. Currently, the burrs on the surface of the metal bracket are generally removed by felt grinding, which is inefficient. At the same time, during the grinding process, the felt will drive the burrs to move on the surface of the bracket, which may leave scratches on the surface of the bracket. Utility Model Content

[0015] Compared with the prior art, the utility model provides a surface treatment device for a metal bracket of an electronic circuit board, which has the following beneficial effects:

[0016] 1. The utility model sets the solenoid valve, which is symmetrically installed at the left and right ends of the tee in a mirror-image manner, and the other end of the solenoid valve is connected to the elbow.
