Description

Technical Field

[0001] This utility model relates to the field of circuit board drilling technology, and in particular to a batch drilling device for circuit board processing. Background Technology

[0002] Circuit board drilling is one of the core processes in manufacturing printed circuit boards (PCBs). It involves creating holes in the substrate for electrical connections or component mounting. Precise drilling with mechanical drill bits ensures continuity between different circuit layers and secure mounting of components. Traditional mechanical drilling uses high-speed rotating carbide drill bits, automatically positioning the drill according to design coordinates. Before drilling, the board material must be fixed, a matching drill bit selected, and parameters such as rotation speed and feed rate adjusted. Drilling quality directly affects circuit performance. With the miniaturization of electronic devices, drilling technology is constantly being upgraded. For example, environmentally friendly equipment and automated processes are being introduced to improve efficiency while balancing accuracy and cost, enabling high-quality results even in small-batch production.

[0003] For batch drilling of small-volume circuit boards, when drilling a single circuit board, the circuit board needs to be placed on the drilling table and fixed with a fixture. Manually aligning and clamping the circuit board is inefficient and inaccurate, and the drilling process requires a long waiting time. The inability to make reasonable use of the waiting time leads to low drilling efficiency and is not conducive to batch drilling of circuit boards. Utility Model Content

[0004] This utility model provides a batch drilling device for circuit board processing, which solves the problem that when drilling a single circuit board, it is necessary to place the circuit board on the drilling table and fix it with a clamp. The manual alignment and clamping of the circuit board is inefficient and inaccurate, and the drilling process requires a long waiting time, which cannot be used reasonably, resulting in low drilling efficiency and is not conducive to the batch drilling of circuit boards.

[0005] This utility model provides a batch drilling device for circuit board processing, specifically including: a circuit board drilling machine, a horizontally adjustable drilling machine above the circuit board drilling machine, a front and rear adjusting platform above the circuit board drilling machine, a shifting drive motor fixedly connected in the middle of the front and rear adjusting platform, a multi-station drilling platform fixedly connected to the upper end of the rotating shaft of the shifting drive motor, a locking push cylinder fixedly connected to the upper rear edge of the shifting drive motor, four circuit board placement openings on the multi-station drilling platform, an outer positioning plate slidably connected inside the circuit board placement opening, a connecting push frame fixedly connected to the outer positioning plate, the connecting push frame located below the multi-station drilling platform, two side clamps movably connected inside the circuit board placement opening, a linkage inclined groove opened on the side clamps, the connecting push frame is a "T" shaped frame, push frame levers are provided at both ends of the connecting push frame, and the push frame levers are slidably connected to the linkage inclined grooves.

[0006] Furthermore, a central limiting platform with a square boss structure is fixedly connected to the center of the upper surface of the multi-station drilling platform, and the four edges of the central limiting platform are respectively connected to four circuit board placement ports.

[0007] Furthermore, side grooves are respectively opened through the two sides of the circuit board placement opening, and a side guide rod is fixedly connected to the front and rear of the inner wall of the side groove.

[0008] Furthermore, an outer sliding groove is longitudinally opened on the side of the circuit board placement port away from the center of the multi-station drilling platform, and an outer guide rod is fixedly connected to the left and right sides of the outer sliding groove.

[0009] Furthermore, the outer positioning plate is slidably connected inside the outer sliding groove, and an outer plate guide opening is provided on the edge of the outer positioning plate, with the outer plate guide opening slidably connected to the outer guide rod.

[0010] Furthermore, an outer plate reset spring is fixedly connected to one end of the outer positioning plate away from the center of the multi-station drilling rig, and the other end of the outer plate reset spring is fixedly connected to an outer sliding groove.

[0011] Furthermore, the side clamp is slidably connected inside the side groove, and side plate guide openings are provided at the front and rear of the side clamp, with side plate guide openings slidably connected to the side guide rod.

[0012] This utility model provides a batch drilling device for circuit board processing, which has the following advantages: The circuit board drilling device of this utility model is used for batch drilling of small-volume circuit boards. It is equipped with four mounting positions for circuit boards. When drilling circuit boards, four circuit boards can be installed through the four mounting positions respectively. The multi-station drilling table is driven by the shift drive motor to rotate and pass under the horizontal adjustment drill to drill the circuit boards sequentially. This can improve the efficiency and continuity of batch drilling of circuit boards. During drilling, the circuit board is installed through the circuit board mounting position at the front, while the circuit board in the rear mounting position is located under the horizontal adjustment drill. The horizontal adjustment drill is used to drill the circuit board. During drilling, the circuit board can be loaded, reducing drilling waiting time and improving drilling efficiency.

[0013] In addition, it is equipped with automatic clamping and alignment functions for circuit boards. When the circuit board is installed above the circuit board placement opening, the outer positioning plate and the side clamping plate are away from the edge of the circuit board. When the rotation driven by the shifting drive motor is rotated to the bottom of the horizontal adjustment drill, the locking push cylinder is opened, pushing the connecting push frame towards the center of the multi-station drill table, which drives the outer positioning plate to move towards the circuit board. At the same time, the push frame lever slides along the linkage inclined groove, which drives the side clamping plate to move towards the middle of the circuit board, thus fixing and clamping the circuit board. The circuit board can be quickly aligned and fixed without the operator having to precisely adjust the placement position. Attached Figure Description

[0019] Example 1: Please refer to Figures 1 to 6 : This utility model proposes a batch drilling device for circuit board processing, comprising: a circuit board drilling machine 1, a horizontally adjustable drilling machine 2 above the circuit board drilling machine 1, a front and rear adjusting platform 3 above the circuit board drilling machine 1, a shifting drive motor 4 fixedly connected in the middle of the front and rear adjusting platform 3, a multi-station drilling platform 5 fixedly connected to the upper end of the rotating shaft of the shifting drive motor 4, a locking push cylinder 6 fixedly connected to the upper rear edge of the shifting drive motor 4, four circuit board placement openings 501 on the multi-station drilling platform 5, an outer positioning plate 8 slidably connected inside the circuit board placement opening 501, a connecting push frame 7 fixedly connected to the outer positioning plate 8, the connecting push frame 7 being located below the multi-station drilling platform 5, two side clamps 9 movably connected inside the circuit board placement opening 501, a linkage inclined groove 901 inclinedly opened on the side clamps 9, and the connecting push frame 7 being a "T" shaped frame. 7 has pusher levers 701 at both ends, which are slidably connected to the linkage inclined groove 901. Under normal conditions, the connecting pusher 7 is close to the outer edge of the multi-station drilling platform 5 under the tension of the outer plate reset spring 801, and the two side clamps 9 are close to the side edge of the circuit board placement opening 501, so that the circuit board can be placed in the center of the circuit board placement opening 501. When the connecting pusher 7 located below the horizontal adjustment drilling machine 2 is pushed towards the center of the multi-station drilling platform 5 by the locking push cylinder 6, it pushes the outer positioning plate 8 to move towards the center of the circuit board placement opening 501. At the same time, under the sliding connection between the pusher lever 701 and the linkage inclined groove 901, the side clamps 9 are pushed towards the center of the circuit board placement opening 501. Under the joint action of the side clamps 9 and the outer positioning plate 8, the circuit board is aligned and clamped, and the horizontal adjustment drilling machine 2 can be controlled to drill the circuit board.

[0020] In this embodiment of the present disclosure, a central limiting platform 502 with a square boss structure is fixedly connected to the center of the upper surface of the multi-station drilling platform 5. The four edges of the central limiting platform 502 are respectively connected to four circuit board placement openings 501. The central limiting platform 502 serves as the inner limiting edge of the circuit board placement opening 501, so that the inner edge of the circuit board fits and is limited with the central limiting platform 502.

[0021] In this embodiment, side grooves 503 are provided through the edges of the circuit board placement opening 501. A side guide rod 504 is fixedly connected to the front and rear of the inner wall of the side groove 503. An outer groove 505 is provided through the side of the circuit board placement opening 501 away from the center of the multi-station drilling platform 5. An outer guide rod 506 is fixedly connected to the left and right of the inner side of the outer groove 505. An outer positioning plate 8 is slidably connected inside the outer groove 505. An outer plate guide opening 802 is provided on the edge of the outer positioning plate 8. The outer plate guide opening 802 is slidably connected to the outer guide rod 506 to guide the movement of the outer positioning plate 8. The side clamping plate 9 is slidably connected inside the side groove 503. A side plate guide opening 902 is provided at the front and rear of the side clamping plate 9. The side plate guide opening 902 is slidably connected to the side guide rod 504 to guide the movement of the side clamping plate 9 to keep the angle of the side clamping plate 9 unchanged and to move linearly under the linkage of the connecting pusher 7.

[0022] In Example 2, based on Example 1, an outer plate reset spring 801 is fixedly connected to one end of the outer positioning plate 8 away from the center of the multi-station drilling platform 5, and an outer slide groove 505 is fixedly connected to the other end of the outer plate reset spring 801. Under normal conditions, the outer plate reset spring 801 pulls the outer positioning plate 8 and the connecting push frame 7 away from the center of the multi-station drilling platform 5, so that the outer positioning plate 8 and the side clamp 9 are away from the circuit board and close to the edge of the circuit board placement opening 501, which facilitates the placement and retrieval of the circuit board.

[0023] The working principle of this embodiment is as follows: Under normal conditions, the connecting pusher 7 is close to the outer edge of the multi-station drilling platform 5 under the tension of the outer plate reset spring 801, and the two side clamps 9 are close to the side edges of the circuit board placement opening 501, reserving a large space for the circuit board placement. The operator places the circuit board in the center of the circuit board placement opening 501. The shift drive motor 4 starts intermittently and drives the multi-station drilling platform 5 to rotate intermittently. As the multi-station drilling platform 5 rotates, it transports the circuit board to the lower part of the horizontal adjustment drilling machine 2. The locking push cylinder 6 is activated, which pushes the connecting pusher 7 towards the center of the circuit board placement opening 501, thereby driving the outer positioning... The board 8 moves towards the center of the circuit board placement opening 501 and fits against the outer edge of the circuit board. At the same time, as the connecting pusher 7 moves, the pusher lever 701 and the linkage inclined groove 901 form a sliding connection, pushing the side clamping plate 9 towards the center of the circuit board placement opening 501 to align and clamp the circuit board. Then, the horizontal adjustment drill 2 is started to drill holes in the circuit board. After drilling is completed, the locking pusher 6 is controlled to retract. Under the contraction of the outer plate reset tension spring 801, the outer positioning plate 8 and the side clamping plate 9 move outward. As the multi-station drill table 5 rotates, the circuit board is transferred to the front of the device, which facilitates the picking up of finished circuit boards and the loading of undrilled circuit boards.
