Description

Technical Field

[0001] This utility model relates to the field of PCB processing technology, and in particular to a PCB processing equipment for stepped holes and tapered holes. Background Technology

[0002] PCB drilling equipment is a machine used in the drilling process during PCB manufacturing. A PCB, also known as a printed circuit board, is an important electronic component, serving as the support for electronic components and the carrier for their electrical connections. A PCB consists of several layers of insulating substrate with connecting wires and solder pads for assembling and soldering electronic components. Holes on a PCB can be stepped or tapered, and drilling these holes requires various drill bits of different sizes.

[0003] For example, the prior art Chinese patent publication number "CN213305872U" provides a drilling device for PCB circuit board processing, including a housing, the bottom of which is fixedly connected to the top of a counterweight, the top of which is fixedly connected to the right side of the top of the counterweight inside the housing, the top of which has a waste material slot, the top of which is fixedly connected to the left side of the arc-shaped housing corresponding to the waste material slot, the bottom of the drilling seat corresponding to the top of the waste material slot inside the housing, the drilling seat having a discharge hole, the bottom of which is fixedly connected to the top of the drilling seat, and the right end of a first air inlet pipe fixedly connected to the left side of the housing near the waste material slot.

[0004] The device, through its air inlet shell and discharge hole, discharges waste material generated after drilling into the waste material trough of the waste material seat through the discharge hole. The first motor drives the air inlet fan to rotate, and the air is quickly circulated into and out of the waste material trough through the second air inlet pipe. Under the action of the air, the waste material in the discharge trough is discharged out of the shell.

[0005] Existing PCB processing equipment for stepped and tapered holes requires drilling holes of different shapes, such as stepped and tapered holes, when the PCB is placed on the processing table for drilling. When the drill bit drills through the PCB, it can cause impact damage between the bottom of the drill bit and the processing table. The bottom of the PCB is not suspended. Moreover, the position of the drilled holes on the PCB surface is variable, and the position of the PCB cannot be flexibly adjusted and tightened according to the position of the drilled holes on the PCB surface.

[0006] Therefore, a PCB processing equipment for stepped holes and tapered holes is proposed. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies where the drilling positions on the PCB surface are variable and the PCB position cannot be flexibly adjusted and tightened according to the required drilling positions. Therefore, this invention proposes a PCB processing equipment for stepped holes and tapered holes.

[0008] To achieve the above objectives, this utility model provides the following technical solution: Design a PCB processing equipment for stepped holes and tapered holes, including a processing table, with support legs fixed at the four corners of the bottom end of the processing table, a frame fixed at one end of the top end of the processing table, a drilling head installed at the top of the frame, a drill bit inserted into the bottom end of the drilling head, a fastening pin for removing and installing the drill bit installed on the outer side of the bottom end of the drilling head, a support frame installed below the drilling head, a support plate installed at the bottom inside the support frame, a through hole for the drill bit to pass through on the surface of the support plate, and a clamping mechanism for PCB abutment placement installed at the four corners of the top of the support plate. The tightening mechanism includes an adjusting plate slidably installed at the four corners of the top of the support frame, a tightening bolt that rotates through the inner end of the adjusting plate, and an abutment plate fixed to the bottom end of the tightening bolt.

[0009] Furthermore, the processing table is horizontally arranged, and chip removal grooves are evenly opened on its surface. The chip removal grooves are elongated and horizontally arranged. First connecting holes are opened on both sides of the surface of the processing table, and the first connecting holes are staggered with the chip removal grooves.

[0010] Furthermore, a support rod slides through the inside of the first connecting hole. The support rod is fixed to both sides of the bottom end of the support frame. The support rod is a threaded rod structure and is vertically arranged. A first nut is connected to its surface at the position above and below the first connecting hole.

[0011] Furthermore, the support frame is a rectangular frame structure and is horizontally arranged. It has an overlapping groove at its bottom, and a hollow groove is opened in the middle of the overlapping groove. The bottom edge of the support plate overlaps the bottom of the overlapping groove.

[0012] Furthermore, the support plate has positioning holes on both sides, and the overlapping groove has an insertion hole in the middle of its side, with the insertion hole and the positioning hole being horizontally aligned.

[0013] Furthermore, a positioning rod slides through the inside of the insertion hole, the inner end of the positioning rod slides into the positioning hole, a limit plate is fixed to the outer end of the positioning rod, and a tension spring is sleeved on the outer end surface of the positioning rod. The two ends of the tension spring are respectively connected to the inner side of the limit plate and the outer side of the support frame.

[0014] Furthermore, connecting columns are fixed at the four corners of the top of the support frame, and the surface of the adjusting plate has an adjusting groove. The connecting columns slide through the adjusting groove. The connecting columns are threaded column structures, and a second nut is connected to their surface at the top of the adjusting plate.

[0015] Furthermore, the connecting column is vertically arranged, the adjusting plate and the adjusting groove are both elongated structures and are both horizontally arranged, the inner end of the adjusting plate has a second connecting hole, the second connecting hole is a threaded hole structure, the tightening bolt rotates vertically through the second connecting hole, and the abutment plate is horizontally arranged above the support plate.

[0016] The PCB processing equipment for stepped holes and tapered holes proposed in this utility model has the following advantages: 1. This utility model features a detachable support rod mounted on the surface of a processing table. The support frame is suspended on the processing table via the support rod, while the support plate is positioned using an overlap groove and a positioning rod. In this way, the bottom end of the support plate is suspended, and the PCB is stably placed on the top of the support plate by a clamping mechanism. When drilling, the drilling position is located directly above the through hole, and different drill bits can be removed and replaced at the bottom of the drilling head using a fastening pin to drill holes of different shapes on the PCB. Furthermore, the drill bit will not be damaged by impact after drilling through the PCB, thus protecting the safety of the drill bit.

[0017] 2. In this utility model, adjustment plates are detachably installed at the four corners of the top of the support frame via connecting columns. Moreover, the adjustment plates can be rotated and horizontally adjusted at the top of the support frame via adjustment slots. This allows for adjustment of the position of the tightening bolts and the abutment plate above the support plate. Therefore, when drilling holes on the PCB, the adjustment plates can be flexibly moved and aligned with the top of the through holes according to the required drilling positions on the PCB surface. The position of the abutment plate can also be flexibly adjusted via the adjustment plates, thus stably abutting the PCB against the top of the support plate, facilitating stable drilling.
