Description

Technical Field

[0002] According to the published patent CN212086609U, a drilling device for circuit board processing includes a worktable, a drilling mechanism that can move up and down on the worktable, and a foot pedal drive unit on the worktable, which combines hand operation and foot operation, and allocates more operating space for hand operation. However, it still has the following shortcomings.

[0003] The aforementioned equipment has the problem that the circuit board often becomes misaligned due to vibration during the drilling process. Once the circuit board becomes misaligned, it will cause a certain error in the drilling position, resulting in poor equipment reliability. Therefore, we propose a drilling device for circuit board processing. Utility Model Content

Through the limiting mechanism and the cleaning mechanism, it solves the problem that when drilling circuit boards, the circuit boards often become misaligned due to vibration during the drilling process. Once the circuit board is misaligned, the drilling position will have a certain error, resulting in poor equipment reliability.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a drilling device for circuit board processing, comprising a fixed plate, a plurality of supporting legs fixedly connected to the bottom outer wall of the fixed plate, a sliding seat fixedly connected to the top outer wall of the fixed plate, a sliding groove formed on the inner wall of the sliding seat, a slide rail slidably connected to the inner wall of the sliding groove, an electric telescopic rod fixedly connected to the outer wall of the slide rail, the outer wall of the electric telescopic rod being fixedly connected to the inner wall of the fixed plate, a drilling machine slidably connected to the inner wall of the slide rail, a second sliding groove formed on the inner wall of the sliding seat, a second slide rail slidably connected to the inner wall of the second sliding groove, an electric telescopic rod slidably connected to the outer wall of the second slide rail, the outer wall of the electric telescopic rod slidably connected to the inner wall of the sliding seat, and a limit mechanism provided on the top outer wall of the fixed plate;

[0007] The limiting mechanism includes a placement seat, the bottom outer wall of which is fixedly connected to the bottom outer wall of a fixing plate, and a plurality of worm gear seats are fixedly connected to the bottom outer wall of the fixing plate.

[0008] Furthermore, a worm is rotatably connected to the inner wall of several worm seats, a throttle is fixedly connected to the outer wall of the worm, a gear is rotatably connected to the bottom outer wall of the fixing plate, a worm wheel is fixedly connected to the bottom outer wall of the gear, and the outer wall of the worm wheel meshes with the outer wall of the worm.

[0009] Furthermore, the inner wall of the fixing plate is provided with a plurality of sliding grooves, and the inner walls of the plurality of sliding grooves are slidably connected to limit plates. The bottom outer wall of the limit plate is fixedly connected to a rack, and the outer wall of the rack meshes with the outer wall of the gear.

[0010] Furthermore, the inner wall of the fixed plate is provided with a cleaning mechanism, which includes a vacuum head, the outer wall of which is fixedly connected to the inner wall of the fixed plate.

[0011] Furthermore, a filter box is fixedly connected to the bottom outer wall of the vacuum head, a push handle is slidably connected to the inner wall of the filter box, and a scraper is fixedly connected to the outer wall of the push handle.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting a limiting plate, allows the circuit board to be directly placed between several limiting plates in the placement base. Then, by rotating the handle clockwise, the handle will drive the worm gear to rotate, the worm gear will drive the gear to rotate, the gear will drive several racks to move, and the racks will drive the limiting plates to move. The limiting plates will move closer to each other and clamp the circuit board during the process to prevent it from shifting. This achieves a stable clamping of the circuit board and prevents it from being misaligned due to vibration during drilling, thus avoiding errors in the drilling position caused by misalignment of the circuit board.

[0017] 2. This utility model incorporates a scraper. During drilling, a fan can be activated, which sucks the processing debris into the filter box via a suction head. The filter screen filters the debris onto its surface. Pushing the handle towards the collection box moves the scraper, which scrapes the debris accumulated on the filter screen into the collection drawer. When it is necessary to empty the debris, the collection drawer along with the collected debris can be pulled out from the slide four to the emptying point. This allows for the unified cleaning and collection of a large amount of debris generated during drilling of the circuit board, preventing debris from splashing to the outside and facilitating unified emptying.
