Description

Drilling device for scrapping printed circuit board

Technical Field

The utility model relates to the field of auxiliary equipment for producing printed circuit boards, in particular to a drilling device for scrapping a printed circuit board.

Background

In order to improve the production efficiency of the PCB, a batch of circuit structures are often printed on a large circuit substrate, and finally cut into individual PCBs. However, defective products are inevitably generated in the production process, and if the marks are not timely marked, bad products can be produced. In fact, during the production process, not only marking but also punching damage can be performed, and the area with problems on the printed circuit board is scrapped.

Punching the printed circuit board creates debris that contains conductive metal and if the debris drifts to other intact areas on the printed circuit board, it is likely that the quality-free circuit board will be damaged. If the sweeping mode is adopted to avoid the chips to stay on the circuit board, the phenomenon that the chips fall on the circuit board is obviously not cured, the production environment is affected, and the defective rate is increased. In the utility model with the application number of 202120606597.X, an air draft device is arranged in the workbench, so that the problem of timely cleaning of chips can be solved. However, the structure of the PCB punching apparatus in this patent is complicated, the use is inconvenient and flexible, the portion of the whole PCB where the problem occurs is random in nature, the PCB is loaded onto the punching apparatus, and then machine adjustment and punching are performed, which is time-consuming and laborious.

The following describes the technical solution of the present utility model and how the technical solution solves the technical problems described above with specific examples.

The present application provides a drilling apparatus for printed circuit board rejection, as shown in fig. 1, including a hand drill 100, a dust collector 200, and a dust collection assembly 300; the hand drill 100 may be used directly with a conventional hand-held electric drill, which is used at ordinary times to drill holes in the marking of the printed circuit board 10, breaking the circuit board in that area and making it clear of scrap. The hand drill 100 includes a drill body, a handle, a drill chuck 110, and a drill bit 120, and the drill chuck 110 is an exposed rotating portion of the hand drill 100 for loading the drill bit 120. The dust assembly 300 is used for absorbing scraps generated in the drilling operation, and covers the outside of the drill chuck 110, and the drill bit 120 is partially exposed outside the dust assembly 300.

As shown in fig. 1, the dust assembly 300 includes a mounting cylinder 310, a sleeve 320 and a dust suction head 330, the mounting cylinder 310 is fixedly connected to an end surface of the hand drill 100 on one side where the drill bit 120 is disposed, the drill chuck 110 of the hand drill 100 is disposed in the mounting cylinder 310, the drill bit 120 of the hand drill 100 is disposed in the sleeve 320, the sleeve 320 is communicated with the mounting cylinder 310, the dust suction head 330 is disposed at the top end of the mounting cylinder 310, and the top end of the drill bit 120 is exposed out of the dust suction head 330; the cleaner 200 communicates with the mounting cylinder 310 through a suction hose.

According to the drilling device for scrapping the printed circuit board, the dust collecting assembly 300 is wrapped outside the hand drill 100, and air is sucked from the dust collecting assembly 300 through the dust collector 200, so that scraps generated at the drill bit 120 of the hand drill 100 can be sucked into the dust collecting head 330 and enter the mounting cylinder 310 and then flow into the dust collector 200, and when the printed circuit board with product defects is punched, scraps can be cleaned quickly, and the main structure of the drilling device is the hand drill 100, and the drilling device is simple in structure and convenient and flexible to use.

Optionally, in one embodiment of the present application, the tail end of the mounting barrel 310 is provided with an external threaded portion, the end surface of the hand drill 100 is provided with a threaded groove matching the mounting barrel 310, and the mounting barrel 310 is detachably connected to the hand drill 100. The passage of the mounting cylinder 310 communicating with the outside is located at the sleeve 320 and the suction head 330, and suction of the cleaner 200 can create a negative pressure in the mounting cylinder 310, and debris at the suction head 330 can be sucked into the mounting cylinder 310. By removably connecting the mounting barrel 310 to the hand drill 100, the mounting barrel 310 and the hand drill 100 can be cleaned at regular intervals.

Alternatively, in one embodiment of the present application, as shown in fig. 1-3, the cleaning head 330 is a horn-shaped connector. The horn-shaped dust collection head 330 is adopted, and the large mouth is outwards, so that the coverage area of the dust collection head 330 can be increased, and the absorption rate of chips can be improved. The cleaning head 330 may be made of transparent plastic. In addition, as shown in fig. 2, the cannula 320 is a telescoping tube. The telescopic tube is used as the sleeve 320, for example, a corrugated tube can be used, the top end surface of the dust collection head 330 can be flush with the top end of the drill bit 120, and when drilling, the telescopic tube is covered on a PCB to be drilled, so that fragments can be completely prevented from jumping and being blown off by the rotary drill bit 120.

Alternatively, in yet another embodiment of the present application, as shown in FIG. 2, the inner wall of the mounting barrel 310 is spaced from the outer wall of the drill chuck 110 by 2-5 mm. In this embodiment, the wall thickness of the inner cavity of the mounting cylinder 310 is larger, and the wall thickness is closer to the hand drill 100, so that the inner cavity space of the mounting cylinder 310 can be reduced, the suction force of the dust collector 200 is beneficial to being concentrated to the sleeve 320 and the dust collection head 330, and the suction force of the dust collection assembly 300 is improved.

Alternatively, in another embodiment of the present application, as shown in fig. 3, a circular diaphragm 311 is provided in the mounting cylinder 310, the diaphragm 311 is located near the drill chuck 110, and the dust suction hose 210 is connected to the peripheral side surface of the mounting cylinder 310 between the diaphragm 311 and the lower end surface of the mounting cylinder 310. By the diaphragm 311, the space for movement of debris within the mounting cylinder 310 is reduced, ensuring that more debris is drawn by the cleaner 200. Specifically, in one embodiment, the inner side wall of the diaphragm 311 is provided with a brush 312, and the tip of the brush 312 may abut against the drill chuck 110. By providing the brush body 312, it is possible to further close the space between the mounting cylinder 310 and the hand drill 100 while avoiding interference of the mounting cylinder 310 with the rotating drill chuck 110.

It will be appreciated by those skilled in the art that in the description herein, unless specifically stated and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.

In the description of the present specification, a particular feature, structure, material, or characteristic may be combined in any suitable manner in one or more embodiments or examples.
