DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-4 As shown, the utility model provides a circuit board drilling mechanism, which is mainly used for placing and fixing the circuit board, and then drilling the circuit board. The circuit board drilling is suitable for batch drilling of circuit boards. During processing, a corresponding fixture is used to fix its position. The specific structure mainly includes a processing table 1, and the processing table 1 is connected to a fixture 2 fixed on the surface. The surface of the fixture 2 is provided with two limiting grooves 3 for placing the circuit board 19, and the bottom of the limiting groove 3 is provided with four holes 4 for drilling. The fixture 2 on the processing table 1 is used to place and fix the position of the circuit board 19. The two can be detached to replace the fixture 2 suitable for different circuit boards 19, which can meet the use of drilling circuit boards 19 of different types or rules. The two limiting grooves 3 are distributed in the same direction on the surface of the fixture 2. However, the position where the hole 4 is provided at the bottom of the limiting groove 3 is the position where the circuit board 19 is drilled. One or more positions can be selected for drilling. When drilling, the drill bit 9 of the machine head 8 passes through the circuit board 19 placed in the limiting groove 3 until it reaches the inside of the hole 4.

[0024] A velvet layer 10 is also adhered to the bottom of the limiting groove 3. The velvet layer 10 can be glued to the bottom of the limiting groove. When the circuit board 19 is placed in the limiting groove 3 and fixed, the velvet layer 10 at the bottom can, on the one hand, reduce the damage caused by friction between the bottom of the circuit board 19 and the clamp 2. On the other hand, it can increase the friction between the two to improve the fixation of the circuit board 19 after placement, and prevent the circuit board 19 from shifting during the drilling process.

[0025] Both ends of the hole 4 are connected, and the end is directly connected to the bottom of the fixture 2. During the drilling process, in order to better insert the drill bit 9 used for drilling and discharge the debris of the product during drilling, an inner concave space is added at the position where the bottom of the fixture 2 contacts the processing table 1. However, the ends of all the holes 4 lead to this space. The debris generated during drilling can fall into the space through the hole 4, avoiding the inability to drill due to clogging by debris. When it is necessary to clean the internal debris, the user can remove the fixture 2 on the surface of the processing table 1 for cleaning.

[0026] The clamp 2 is also provided with a pressure cover 5 covering the upper end surface and the outer side surface. The main function of the pressure cover 5 is to press on the surface of the clamp 2 to prevent the circuit board 19 from being ejected during drilling. It can also press the circuit board 19 to prevent the circuit board 19 from shifting during drilling. The bottom of the pressure cover 5 can be locked and fixed by locking screws 11 distributed around it, and the user can remove the locking screws 11 to take out the pressure cover 5 and replace the circuit board 19 placed in the limit groove 3.

[0027] Two hollow parts 6 are provided on the top of the pressure cover 5, which are connected to the corresponding limit grooves 3. The hollow parts 6 are provided with six protrusions for pressing on the protrusions 7 on the surface of the circuit board 19. The hollow parts 6 directly expose the surface of the circuit board. When drilling, the circuit board 19 is also drilled through the position of the hollow parts 6. In order to prevent the circuit board 19 placed in the limit groove 3 from escaping, the outline size of the hollow part 6 is set on the inner side of the opening outline of the limit groove 3, but it cannot affect the exposure of the drilling position. Moreover, the hollow part 6 is also tightly attached to the surface of the circuit board 19 by six protrusions around it to strengthen the fixation.

[0028] A movable machine head 8 is provided above the fixture 2, and the machine head 8 is connected to a drill bit 9 for drilling holes in the limit slot 3. When drilling holes in the circuit board 19, the drill bit 9 rotates rapidly under the drive of the machine head 8. Before drilling, the user can set the drilling position through the operation panel 18 at the front end of the front stage 1. Then, when the machine head 8 adjusts the drilling position, the X-axis moving module 12, the Y-axis moving module 13 and the Z-axis moving module 14 jointly complete the adjustment in three directions. The X-axis moving module 12 moves forward and backward in the X-axis direction, the Y-axis moving module 13 moves left and right in the Y-axis direction, and the Z-axis moving module 14 moves up and down in the Z-axis direction. After repeated adjustment and movement, it finally falls to different positions for drilling processing.

[0029] An X-axis driving motor 15 for driving and controlling the movement of the Y-axis moving module 13 is provided at the end of the X-axis moving module 12 on both sides, a Y-axis driving motor 16 for driving and controlling the Z-axis moving module 14 is provided on one side of the Y-axis moving module 13, and the Z-axis moving module 14 is provided with a Z-axis driving motor 17 for driving and controlling the machine head 8. Each moving module is provided with a corresponding driving motor, which provides power for movement and performs position adjustment.

[0030] Compared with the traditional technology, the present technical solution can place multiple circuit boards 19 on the fixture 2 at one time for drilling processing, which greatly improves the processing efficiency. At the same time, a pressure cover 5 is added to the surface of the fixture 2 to flatten and fix the circuit board 19, which further strengthens the position fixity of the circuit board 19 during drilling processing, avoids the circuit board 19 from moving or being pushed upward, and improves the quality of the drilling processing of the circuit board 19.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
