Description

Technical Field

[0001] The utility model relates to the technical field of PCB micro-drilling, and more specifically to a DLC multi-layer coating deposition PCB micro-drilling. Background Art

[0002] With the continuous development of society and the continuous advancement of science and technology, electronic products are now everywhere in our lives, and the most important part of electronic products: PCB circuit boards have become the most needed thing in today's era. With the continuous updating of electronic products, the processing requirements for PCB circuit boards are becoming more and more stringent. Because PCB circuit boards need to be welded and installed with various components before they can be used together, if you want to drill holes on the PCB circuit boards, you need to use corresponding micro drills for processing.

[0003] The existing drill bits used for PCB circuit board processing are prone to shaking when drilling. Once the drill bit shakes during drilling, it will cause the drill bit to deviate and the drilled hole to be too large, causing damage to the PCB circuit board. Therefore, it is necessary to design a DLC multi-layer coating deposition PCB micro drill to solve the above problems. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a DLC multi-layer coating deposition PCB micro drill, which can achieve the effect of buffering and reducing shock on the drill bit when shaking occurs during the use of the PCB micro drill body and the drill bit to process and drill holes in the PCB circuit board, thereby avoiding the drill bit position deviation and causing damage to the PCB circuit board.

[0006] Technical Solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] The DLC multi-layer coating deposition PCB micro drill comprises a PCB micro drill body with a drill bit at the bottom end, a threaded shaft is fixedly connected to the top end of the PCB micro drill body, a baffle is fixedly connected to the bottom side wall of the threaded shaft, a shock-absorbing spring is arranged on the outer sleeve of the PCB micro drill body, a connecting plate is fixedly connected to the top end of the shock-absorbing spring, and the connecting plate is sleeved on the surface of the threaded shaft and contacts the baffle, a sliding sleeve is arranged on the outer sleeve of the PCB micro drill body, a protective pad is fixedly connected to the bottom end of the sliding sleeve, a card slot is drilled on the top end of the protective pad, a bottom plate is fixedly connected to the bottom end of the shock-absorbing spring, a card block is fixedly connected to the bottom end of the bottom plate, and the card block is engaged with the card slot.

[0009] Furthermore, the protective pad and the clamping block are both made of rubber material, and the clamping block is threadedly connected to the clamping slot.

[0010] Furthermore, the length of the PCB micro drill body is longer than the length of the sliding sleeve by the required drilling length.

[0011] Furthermore, the diameter of the connecting plate is larger than the diameter of the PCB micro drill body and smaller than the diameter of the baffle.

[0012] Furthermore, a connector is detachably connected to the top end of the threaded shaft, a screw hole is drilled at the bottom end of the connector, and the threaded shaft is threadedly connected to the screw hole.

[0013] Furthermore, a micro motor is installed on the top of the connector, and an output end of the micro motor is connected to the connector.

[0014] Furthermore, the sliding sleeve is made of a transparent acrylic plate material, and the inner wall of the sliding sleeve does not contact the surface of the PCB micro drill body. Beneficial Effects

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) This solution can be realized. When the PCB micro drill body is used, the sliding sleeve can be put on the outside of the PCB micro drill body, and then the shock absorbing spring is put on the threaded shaft through the connecting plate and limited by the baffle, so that the shock absorbing spring is vertically put on the surface of the PCB micro drill body and the sliding sleeve, and then the bottom plate and the protective pad are overlapped and abutted, so that the card block is stuck in the protective pad, thereby playing a supporting role to prevent the PCB micro drill body from falling off when it is extended and retracted in the sliding sleeve, and then the protective pad is abutted against the processing part of the PCB circuit board, and then the PCB micro drill body is driven to drive the drill bit to rotate and drill holes, so that the shock absorbing spring is also compressed while the drill bit moves downward, and the sliding sleeve can be used to buffer and damp the drill bit, effectively achieving the effect of buffering and damping the drill bit when shaking occurs when the PCB micro drill body and the drill bit are used to process and punch holes on the PCB circuit board, thereby preventing the drill bit from shifting.

[0017] (2) When the drill bit is driven to drill, the depth of the drilling can be controlled by the sliding sleeve, and the shock-absorbing spring is sleeved on the threaded shaft through the connecting plate and blocked by the baffle, so that the shock-absorbing spring can remain in a non-rotating state when the PCB micro-drill body rotates, without affecting the use of the PCB micro-drill body and the drill bit.

[0018] (3) The drilling position of the drill can be observed through the sliding sleeve while drilling, and the debris generated during drilling can be shielded. At the same time, the sliding sleeve does not contact the PCB micro-drill body, which can avoid the wear effect caused by the contact between the PCB micro-drill body and the sliding sleeve during rotation.
