Description

Technical Field

[0001] The utility model relates to the technical field of circuit board opening, in particular to an opening device for circuit board processing. Background Technique

[0002] A circuit board is a substrate for supporting, connecting, and conducting electronic components. It is made of insulating materials and covered with wires, pads, and other connecting devices to achieve electrical connection and signal transmission between electronic components. Circuit boards are widely used in the electronics industry and can be used for the manufacturing and assembly of electronic products. During the manufacturing process of circuit boards, it is necessary to use a drilling machine to open holes in them. The purpose of opening holes is to connect components, route wires, and meet other connection requirements;

[0003] During the circuit board opening process, a large amount of waste chips are likely to accumulate on the base, making it inconvenient to clean. Although some bases are provided with discharge holes for chip removal, waste chips are still likely to accumulate in the discharge holes, making the cleaning work more difficult.

[0004] To solve the above problems, an opening device for circuit board processing is proposed in this application. Content of the Utility Model

[0005] Based on the technical problems existing in the background technique, the utility model proposes an opening device for circuit board processing.

[0006] An opening device for circuit board processing proposed by the utility model includes a drilling machine and a base installed at the bottom of the drilling machine;

[0007] An arc-shaped bumping member is installed on the base. A turntable located inside the arc-shaped bumping member and a driving member for driving the turntable to rotate are also installed on the base. A bearing plate is installed on the turntable through an elastic member. A collection chamber is formed inside the bearing plate, and a discharge hole communicating with the collection chamber is formed at the top of the bearing plate. A rod-shaped rolling member that abuts against the arc-shaped bumping member is installed on the outer periphery of the bearing plate;

[0008] A cleaning member for cleaning the discharge hole on the bearing plate is installed on the base.

[0009] Preferably, the arc-shaped bumping member includes an arc-shaped cover installed on the top of the base, and several spaced convex columns are installed inside the arc-shaped cover.

[0010] Preferably, the rod-shaped rolling member includes a fixed rod installed on the side of the bearing plate close to the arc-shaped cover. A rolling groove is formed at one end of the fixed rod close to the arc-shaped cover, and a ball that abuts against the inner wall of the arc-shaped cover is rotatably connected in the rolling groove.

[0011] Preferably, the elastic member includes two springs and two sliders. A chute is formed on the turntable. The two springs are respectively installed at both ends of the chute. The two sliders are respectively installed at opposite ends of the two springs and are slidably connected to the chute. The bearing plate is installed on the two sliders.

[0012] Preferably, the cleaning member includes an electric push rod, a cleaning frame and bristles. The electric push rod is installed on the side of the base. The cleaning frame is installed at the driving end of the electric push rod and is driven by the electric push rod to approach or move away from the bearing plate. The bristles are installed on the cleaning frame and are used for cleaning the discharge holes.

[0013] Preferably, a collection box is received in the collection chamber. An opening communicating with the storage chamber and allowing the collection box to enter and exit is formed on the bearing plate.

[0014] Preferably, the driving member includes a servo motor. An installation chamber is formed in the base. The servo motor is installed in the installation chamber. The center of the bottom of the turntable is connected to the output end of the servo motor.

[0015] The above technical solution of the present utility model has the following beneficial technical effects:

[0016] After the circuit board is processed, waste chips will accumulate in the discharge holes formed on the bearing plate. The turntable can be driven to rotate by the driving member. The rod-shaped rolling members installed on the outer periphery of the bearing plate roll along the inner wall of the arc-shaped bumping member. Under the action of the elastic member, the bearing plate can be shaken back and forth, so that the waste chips accumulated in the discharge holes can fall into the collection chamber formed in the bearing plate. This structure enables the waste chips to automatically fall into the collection chamber through the vibration design and the collection chamber, reducing the manual operation and difficulty of the cleaning work;

[0017] When cleaning the waste chips on the bearing plate by the provided cleaning member, the cleaning member can be adjusted to the bearing plate. When the turntable rotates, the waste chips in the discharge holes on the bearing plate can be cleaned by the cleaning member. Through the design of the cleaning member, the waste chips in the discharge holes can be directly cleaned, simplifying the cleaning process. BRIEF DESCRIPTION OF THE DRAWINGS
