Description

Technical Field

[0001] The utility model relates to the technical field of PCB board processing equipment, and particularly relates to an automatic clamping device for a PIN machine on a PCB board. Background Art

[0002] The PIN machine on the PCB board is mainly used to fix multi-layer boards. The production includes two main processes: PIN insertion and gluing. Among them: PIN insertion means adding a backing plate at the lower end of the PCB board and fixing it by nailing; gluing means installing an aluminum sheet at the upper end of the PCB board after PIN insertion and connecting and fixing it with tape. These steps ensure that the PCB board can remain stable during the processing, avoiding accuracy problems caused by vibration or movement.

[0003] However, there are several problems in the PCB board gluing process: First, the tape used cannot be reused, resulting in high processing costs; second, the later cleaning of the tape is time-consuming and laborious, reducing production efficiency; finally, a large amount of waste tape generated during processing will have an impact on the environment.

[0004] Therefore, in view of the deficiencies of the existing technology, it is necessary to design an automatic clamping device for a PIN machine on a PCB board to solve the above problems.

[0005] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely explaining the technical solution of the present utility model and facilitating the understanding of those skilled in the art. It cannot be considered that the above content is well-known to those skilled in the art just because these contents are described in the background art of the present utility model. Summary of the Utility Model

[0006] To overcome the above deficiencies in the existing technology, the purpose of the present utility model is to disclose an automatic clamping device for a PIN machine on a PCB board, which fixes the PCB board after PIN insertion and the aluminum plate with a positioning clamp instead of tape.

[0007] The present utility model discloses an automatic clamping device for a PIN machine on a PCB board, including a mounting frame, on which a PCB board positioning unit and a positioning clamp mounting unit are provided. Among them,

[0008] The PCB board positioning unit is used to position and fix the PCB board to be processed;

[0009] The positioning clamp mounting unit includes a guiding slideway and a front pressing drive.

A drive motor is provided at the output end of the lifting drive. A milling cutter is provided at the output end of the drive motor. The positioning groove processing unit can process a positioning groove for installing the positioning clip on the backing plate at the lower end of the PCB board, which is convenient for the positioning and installation of the positioning clip and is also beneficial for the later stacking and positioning of the PCB board.

[0014] Preferred technical solution: One side of both the press head and the drive motor is connected to the mounting rack through a slide rail to ensure the stability of their movement process and improve the processing accuracy.

[0015] Preferred technical solution: A clamping plate is provided on one side of the positioning support base to assist in aligning the PCB board and the aluminum sheet.

[0027] Embodiment 1:

[0028] As Figure 1 shown, the automatic clamping device for the PIN machine on the PCB board disclosed by the present utility model includes a mounting frame 100, and a PCB board positioning unit 1, a positioning groove processing unit 2, and a positioning clip mounting unit 3 are arranged on the mounting frame 100. The following will specifically describe the main components of the above-mentioned present utility model:

[0029] As Figure 1 and Figure 3 shown, the PCB board positioning unit 1 includes a positioning support base 11 and a positioning press head assembly 12. The positioning press head assembly 12 includes a lifting drive cylinder 12a, and a press head 12b is arranged at the output end of the lifting drive cylinder 12a. The press head 12b is arranged opposite to the positioning support base 11, and one side of the press head 12b is connected to the mounting frame 100 through a slide rail.

[0030] As Figure 1 and Figure 3 shown, the positioning groove processing unit 2 is located below the positioning support base 11, and includes a lifting drive 21 arranged on the mounting frame 100. A drive motor 22 is arranged at the output end of the lifting drive 21, and a milling cutter 23 for processing the PCB board is arranged at the output end of the drive motor 22. The milling cutter 23 can pass through the positioning support base 11 to process the PCB board, and one side of the drive motor 21a is connected to the mounting frame 100 through a slide rail.

[0031] As Figure 1 and Figure 3 shown, the positioning clip mounting unit 3 includes a guiding slideway 31 and a front pressing drive 32. The front output port of the guiding slideway 31 is arranged on one side of the PCB board positioning unit 1; a positioning clip placement chamber 31a is arranged at the rear end of the guiding slideway 31 for placing the positioning clip for clamping; the output end of the front pressing drive 32 is arranged at the rear end of the positioning clip placement chamber 31a, and can push the positioning clip 4 out from the front output port of the guiding slideway 31 along the axial direction of the guiding slideway 31. A push rod is arranged at the output end of the front pressing drive 32, and the push rod is connected to the output end of the front pressing drive 32 through a coupling 32a. A positioning clip expanding mechanism is arranged at the front output port of the guiding slideway 31.

[0032] Refer toFigure 1 , Figure 2 and Figure 3 As shown in Figure 1 , Figure 2 and Figure 3 , the principle and usage method of the automatic clamping device for the PIN machine on the PCB board of the present utility model are as follows: The PCB board 5 and the aluminum sheet 52 after PIN insertion are aligned with each other on the support seat 11. Then, the lifting drive cylinder 12a drives the pressure head 12b to press and fix the PCB board 5 on the support seat 11; the drive motor 22 is started, and the lifting drive 21 controls the drive motor 22 and the milling cutter 23 to rise and pass through the support seat 11 to machine a positioning groove for installing the positioning clamp 4 at the lower end of the backing plate 51; after the positioning groove is machined, the lifting drive 21 controls the drive motor 22 and the milling cutter 23 to descend. A number of positioning clamps are loaded into the positioning clamp placement compartment 31a. It should be noted that the positioning clamps can be loaded manually in batches here, or a conveying mechanism or a manipulator can be used to replace manual feeding of the positioning clamps. The output end of the front pressing drive 32 advances forward along the guiding slideway 31, so that the positioning clamp 4 in the guiding slideway 31 moves towards the PCB board 5; when the positioning clamp 4 moves to the front end of the guiding slideway 31, the opening size of the positioning clamp 4 is enlarged by the expanding mechanism to exceed the clamping dimension of the PCB board 5, and the front pressing drive 32 continues to push until the positioning clamp 4 is clamped on the PCB board 5 through the positioning groove on the backing plate 51, and the aluminum sheet 52 is positioned and fixed on the PCB board 5 through the positioning clamp 4. During the stacking process of the PCB boards, the positioning groove at the lower end of the PCB board can also be engaged with the positioning clamp 4 at the upper end of the PCB board to reduce the stacking difficulty of the processed PCB boards.
