Description

Technical Field

[0001] The utility model relates to the technical field of ceramic circuit board processing, in particular to a drilling and clamping device for a ceramic circuit board. Background Art

[0002] Ceramic circuit board is a printed circuit board that uses ceramic material as the substrate. Compared with traditional glass fiber reinforced epoxy resin substrates, ceramic circuit boards have many unique performance advantages, making them an ideal choice in specific applications. Ceramic circuit boards have the advantages of high thermal conductivity, low thermal expansion coefficient, excellent electrical properties, high heat resistance and high mechanical strength.

[0003] When drilling holes in ceramic circuit boards, the position of the ceramic circuit boards needs to be restricted so that the laser drill can perform drilling operations. However, ceramic circuit boards are usually embedded in limit grooves that are consistent with their own sizes for fixation. As a result, when processing ceramic circuit boards of different sizes, the processing table with limit grooves of specific sizes needs to be frequently replaced, which is inconvenient to use.

[0004] In view of the above problems, the utility model document proposes a drilling clamping device for a ceramic circuit board. Utility Model Content

[0005] The utility model provides a drilling clamping device for a ceramic circuit board, which solves the disadvantage in the prior art that a ceramic circuit board is usually embedded in a limiting groove consistent with its own size for fixation, resulting in the need to frequently replace a processing table with a limiting groove of a specific size when processing ceramic circuit boards of different sizes, which is inconvenient to use.

[0006] The utility model provides the following technical solutions:

[0007] A drilling and clamping device for a ceramic circuit board, comprising:

[0008] A processing counter, one side of which is not enclosed, and the top of the outer wall of the processing counter is symmetrically provided with two clamping brackets for holding up and clamping the ceramic circuit board;

[0009] The spacing adjustment component is arranged on the processing counter and is used to adjust the spacing between the two clamping brackets, thereby improving the applicability of the device so as to clamp ceramic circuit boards of different sizes.

[0010] In a possible design, the spacing adjustment assembly includes a screw rod rotatably installed in the center of both ends of the inner wall of the processing counter, the screw rod is vertically arranged, and a matching sliding seat is threadedly connected to the screw rod. Two connecting rods are hinged on both sides of the sliding seat, and the other ends of the two connecting rods on the same side pass through the corresponding slide rails on the top of the processing counter and are hinged to the corresponding bottom of the clamping bracket.

[0011] In a possible design, an L-shaped mounting plate is fixedly provided at the bottom of the inner wall of the processing counter, a driving motor is fixedly installed on the L-shaped mounting plate, an output shaft of the driving motor passes through the outer wall of the L-shaped mounting plate and is fixedly provided with a first bevel gear, a second bevel gear is fixedly provided on the screw rod, and the second bevel gear is meshed with the first bevel gear.

[0012] In a possible design, a protective frame is fixedly provided at the bottom of the inner wall of the processing counter to prevent the sliding seat from hitting the first bevel gear, and a through hole for the screw to pass through is provided in the center of the protective frame.

[0013] In a possible design, a T-shaped slider is fixedly provided at the bottom of the clamping bracket for improving its movement stability, and a T-shaped slot is provided on the top of the processing counter for sliding connection with the corresponding T-shaped slider.

[0014] In a possible design, a limiting slider for improving the movement stability of the sliding seat is fixedly provided on one side of the sliding seat, and a limiting slider for slidably connecting with the limiting slider is provided on the side wall of the processing counter.

[0015] In a possible design, the clamping bracket is made of hard rubber.

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0017] In the present application, when in use, the ceramic circuit board is placed on two clamping brackets to prepare for the clamping operation, and then the drive motor is started, and its output shaft drives the first bevel gear to rotate. The first bevel gear drives the screw to rotate by meshing with the second bevel gear. The rotation of the screw causes the sliding seat to move downward on the screw. The movement of the sliding seat drives the clamping bracket to slide in the slide rail through the connecting rod, thereby adjusting the spacing between the two clamping brackets until the spacing of the clamping brackets matches the size of the ceramic circuit board. The drive motor is stopped. The clamping bracket is made of hard rubber material to provide sufficient friction to stably clamp the ceramic circuit board. Then, a drilling device is used to drill the ceramic circuit board. Due to the stable clamping of the clamping bracket, the drilling process is more precise and stable.

[0018] The utility model has the following beneficial effects:

[0019] The utility model adopts the design of the spacing adjustment component, so the device can adapt to ceramic circuit boards of different sizes, thereby improving the applicability and flexibility of the device. The clamping bracket is made of hard rubber material, which can provide sufficient clamping force while avoiding damage to the ceramic circuit board, thereby ensuring the stability of the drilling process.

[0020] In the utility model, the driving motor realizes the automatic rotation of the screw through the transmission of the first bevel gear and the second bevel gear, thereby driving the automatic adjustment of the distance between the clamping brackets, thereby improving the working efficiency. In addition, the protective frame arranged at the bottom of the inner wall of the processing counter can prevent the sliding seat from hitting the first bevel gear when moving downward, thereby ensuring the safe operation of the equipment.

[0021] In the utility model, the T-shaped sliding block arranged at the bottom of the clamping bracket cooperates with the T-shaped sliding groove on the top of the processing counter, and the limiting sliding block on one side of the sliding seat cooperates with the limiting sliding groove on the side wall of the processing counter, both of which improve the stability of the device during the adjustment process.
