Description

Technical Field

[0001] This invention relates to the field of automotive PCB board processing technology, and in particular to an anti-deviation positioning mechanism and drilling machine for automotive PCB board drilling. Background Technology

[0002] Drilling is a key process in the production of automotive PCBs. It requires drilling multiple precise through holes in the PCB for subsequent component soldering and circuit connection. Since automotive PCBs typically have high dimensional accuracy requirements and high circuit density, a positioning mechanism is needed to fix them during the drilling process.

[0003] Chinese patent document CN217573204U discloses a PCB board drilling auxiliary positioning device, including a base, a fixed plate fixedly connected to the top surface of the base, a first positioning hole through the top surface of the fixed plate, a first positioning tube fixedly connected to the top surface of the fixed plate, a PCB board overlapping the top surface of the base, and the PCB board overlapping the fixed plate. A connecting plate fixedly connected to the top surface of the base has a threaded hole and a sliding hole through its surface, and a threaded post threadedly connected to the inner wall of the threaded hole. Rotating the threaded post causes it to push a moving plate into contact with the fixed plate. An external drilling device drills holes in the PCB board through the first positioning hole, the first positioning tube, the second positioning hole, and the second positioning tube. This device facilitates marking the drilling positions on the PCB board using a marking function, avoiding the need for workers to mark the drilling positions on the PCB board beforehand, making the PCB board drilling auxiliary positioning device more convenient to use.

[0004] When the aforementioned PCB board drilling auxiliary positioning device is in use, the fine dust generated during drilling will remain on the PCB board and positioning components, making it difficult to clean. After accumulating to a certain amount, it may affect the stable placement of the PCB board and increase the difficulty of subsequent cleaning of the PCB board. Summary of the Invention

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an anti-offset positioning mechanism and drilling machine for automotive PCB board drilling. This can solve the problem that when the above-mentioned PCB board drilling auxiliary positioning device is used, the fine dust generated during drilling will remain on the PCB board and positioning components, which is not easy to clean. After accumulating a certain amount, it may affect the stable placement of the PCB board and increase the difficulty of subsequent cleaning of the PCB board.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a positioning mechanism for preventing offset during drilling of automotive PCB boards, comprising a hollow platform, a reciprocating feeding mechanism, a multi-directional clamping mechanism, and a dust removal mechanism. The top of the hollow platform has two sets of strip-shaped openings. The reciprocating feeding mechanism is located inside the hollow platform and includes a transmission screw, an internal threaded block, and a mounting block. One inner wall of the hollow platform is rotatably connected to one end of the transmission screw, and the outer wall of the transmission screw is threadedly connected to the internal thread of the internal threaded block. A connecting block is provided at the top of the internal threaded block, and the connecting block passes through the strip-shaped openings and is fixedly connected to the bottom of the mounting block. The multi-directional clamping mechanism... The holding mechanism is located above the hollow platform. The multi-directional clamping mechanism includes a fixed vertical plate, a servo electric cylinder, and a vertical clamping plate. The top of the mounting block is fixedly connected to the bottom of the two sets of fixed vertical plates. A set of servo electric cylinders is fixedly installed on the front side of one set of fixed vertical plates and the rear side of the other set of fixed vertical plates. The free ends of the two sets of servo electric cylinders pass through the fixed vertical plates and are fixedly installed with a set of vertical clamping plates respectively. The dust removal mechanism is located above the hollow platform. The dust removal mechanism includes a partition cover, a high-power fan, and a circular material cylinder.

This allows the partition cover to cover the top of the mounting block, and a high-powered fan blows up the dust, which is then sucked into the circular cylinder for collection. This cleans most of the dust on the PCB board and mounting block, preventing dust accumulation, ensuring stable placement of the PCB board, improving processing quality, and reducing the difficulty of subsequent PCB board cleaning.

[0010] Preferably, the top of the mounting block is fixedly equipped with multiple sets of supporting protrusions.

At the same time, it can be used for PCB boards of various sizes without frequent replacement of positioning components, thus increasing the applicability of the device.

[0026] Furthermore, the dust removal mechanism 7 also includes an internally threaded cover 704, a dust filter plate 705, an exhaust fan 706, and a dust outlet 707. A dust outlet 707 is provided on one side of the partition cover 701, connecting the partition cover 701 and the interior of the circular material cylinder 703. An internally threaded cover 704 is threaded onto one side of the circular material cylinder 703.

A circular opening is provided on one side of the internally threaded cover 704, and an exhaust fan 706 is fixedly installed on one side of the internally threaded cover 704. The exhaust fan 706 overlaps with the circular opening, allowing the partition cover 701 to cover the top of the mounting block 305.

[0030] A drilling machine, comprising the anti-deviation positioning mechanism for drilling and processing automotive PCB boards as described in any of the above claims.

[0031] Working principle: When using this device, one side of the hollow platform 1 is placed on the table of the drilling machine and fixed by the connecting piece 11. At the same time, the support rod 12 is supported on the ground in front of the drilling machine. The PCB board is placed on the supporting protrusion 9 on the top of the mounting block 305. The hollow sliding sleeve 404 is moved to slide on the vertical clamping plate 403. The spacing of the horizontal clamping blocks 409 is adjusted to match the width of the PCB board. Then, the auxiliary knob 407 is turned in sequence to rotate the threaded pressure rod 406. The movement causes the threaded pressure rod 406 to move into the connecting cylinder 405, pressing the anti-slip pad 408 against the outer wall of the vertical clamping plate 403, thus limiting the hollow sliding sleeve 404. The servo electric cylinder 402 is activated, and under the sliding guide of the sliding rod 8, it moves the vertical clamping plate 403, causing the vertical clamping plate 403 and the horizontal clamping block 409 to respectively clamp and position the PCB board on its four sides. The servo motor 301 is activated to drive the transmission screw 302 to rotate, and under the limit of the guide rod 303, the inner... The threaded block 304 moves horizontally within the hollow table 1, causing the mounting block 305 to move and feeding the positioned PCB board into the drilling machine for processing. After processing, the transmission screw 302 rotates in the reverse direction, moving the PCB board from the drilling machine to below the partition cover 701. The electric push rod 6 is then activated to extend, pushing the partition cover 701 downwards and covering the top of the mounting block 305. The high-power fan 702 is then turned on, drawing outside air into the partition cover 701 through the arc-shaped air inlet 13, and then directing the air towards the PCB board. The dust generated during drilling is blown out by the mounting block 305 and placed inside the separator 701. Then, the exhaust fan 706 is turned on to draw air into the circular cylinder 703. The dust blown out is sucked into the circular cylinder 703 through the dust outlet 707. The dust is filtered by the dust filter plate 705 and left inside the circular cylinder 703. The PCB board can then be removed. The inner threaded cover 704 is removed from the circular cylinder 703, leaving the circular cylinder 703 in an open state, allowing the collected dust inside the circular cylinder 703 to be cleaned.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
