Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a hole processing device for circuit boards. Background Technology

[0002] In the fabrication of circuit boards, the demand for diverse hole machining angles is increasing to meet the assembly requirements of different electronic devices. However, existing circuit board hole machining equipment has significant limitations in angle adjustment.

[0003] Currently, traditional hole-making equipment often has fixed angles for its drilling components, or only allows for limited angle adjustment, and the adjustment process is extremely cumbersome. If drilling at different angles is required on a circuit board, operators often need to manually disassemble and reassemble the drilling components, or use complex auxiliary tools for angle calibration. This not only consumes a lot of time and manpower, but also makes it difficult to guarantee adjustment accuracy, easily leading to angle deviations. This results in holes that do not meet design requirements, increasing the scrap rate and consequently affecting the efficiency of the equipment in processing circuit boards.

[0026] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This application provides a hole processing apparatus for a circuit board, including a worktable 1; a support frame 2 is mounted on the surface of the worktable 1, an adjustment component 3 is provided on the inner side of the support frame 2, a lowering component 4 is mounted on the bottom of the adjustment component 3, a rotating component 5 is fixedly mounted on the bottom of the lowering component 4, a fixed frame 6 is fixedly mounted below the rotating component 5, and a drilling component 7 is installed inside the fixed frame 6.

[0028] Rotating assembly 5 includes a rolling ball 501, a groove 502, a rotating frame 503, a first motor 504, and a mounting rod 505. The surface of the rolling ball 501 has staggered grooves 502. Rotating frames 503 are staggeredly mounted on the outer sides of the rolling ball 501. One end of the rotating frame 503 is fixedly mounted with the first motor 504. The mounting rod 505 is installed inside the grooves 502, passing through two sets of rotating frames 503. Adjusting assembly 3 includes a transverse groove 301, an electric slide rail 302, an adjusting plate 303, an electric slide rail 304, and a sliding block 305. The transverse groove 301 is formed on the inner top of the support frame 2. The transverse groove 301 is equipped with an electric slide rail 302, an adjusting plate 303 is installed inside the electric slide rail 302, an electric slide rail 304 is opened inside the adjusting plate 303, and a sliding block 305 is slidably installed on the surface of the electric slide rail 304. The lowering component 4 includes an electric push rod 401 and a mounting bracket 402. The electric push rod 401 is installed below the sliding block 305, and the mounting bracket 402 is installed at the bottom of the electric push rod 401. A rolling ball 501 is installed inside the mounting bracket 402. One end of the rotating bracket 503 passes through the mounting bracket 402 and is fixedly connected to the motor 504.

[0029] Specifically, such as Figures 1 to 5As shown, when hole processing is required on the circuit board, the circuit board is first placed on the surface of the worktable 1. The adsorption assembly 9 starts working, initially fixing the circuit board on the worktable 1 to prevent displacement during processing. Then, the electric slide rail 302 works in the transverse groove 301, driving the adjusting plate 303 to move laterally. At the same time, the electric slide rail 304 drives the sliding block 305 to move longitudinally on the adjusting plate 303. Through the cooperation of transverse and longitudinal movements, the lowering assembly 4 and its connected subsequent components are adjusted to a position approximately above the hole to be processed on the circuit board. If a specific angle is required for processing the hole, the rotating assembly 5 starts operating. The motor 504 starts, driving the rotating frame 503 fixedly connected to it to rotate. Since the rotating frame 503 is staggered on the outside of the rolling ball 501, and the surface of the rolling ball 501 has a rolling groove 502 that cooperates with the rotating frame 503, the rotation of the rotating frame 503 will drive the rolling ball 501 to rotate within the mounting frame 402. The mounting rod 505 passes through the groove 502 and engages with the rolling ball 501. When the rolling ball 501 rotates, it causes the mounting rod 505 to change its angle, thereby adjusting the fixing bracket 6 and drilling assembly 7 fixedly connected to the bottom of the mounting rod 505 to the required drilling angle. After the angle is adjusted, the electric push rod 401 in the lowering assembly 4 is activated, pushing the mounting bracket 402 downward, thereby causing the rotating assembly 5, fixing bracket 6 and drilling assembly 7 to move downward as a whole. When approaching the circuit board, the fixing assembly 8 starts to work, the hydraulic cylinder 801 extends, pushing the pressure plate 802 downward, further pressing and fixing the circuit board, and achieving double fixing with the adsorption assembly 9 to ensure the stability of the circuit board during drilling. Subsequently, the drilling assembly 7 is activated, the motor 701 runs, driving the mounting block 702 and the drill bit 703 installed inside the mounting block 702 to rotate at high speed. The lowering component 4 continues to push the drilling component 7 downward, so that the high-speed rotating drill bit 703 contacts the circuit board and performs drilling. After drilling is completed, the drilling component 7 stops working, the lowering component 4 drives it to reset upward, the hydraulic cylinder 801 of the fixing component 8 retracts, the pressure plate 802 leaves the circuit board, the adsorption component 9 stops adsorption, and the processed circuit board can be removed.

[0030] Furthermore, a fixing frame 6 is fixedly installed at the bottom of the mounting rod 505, and fixing plates 601 are installed on both sides of the fixing frame 6. The fixing assembly 8 and the drilling assembly 7 are installed inside the fixing plate 601. The fixing assembly 7 includes a second motor 701, a mounting block 702 and a drill bit 703. The second motor 701 is installed inside the fixing frame 6, and the mounting block 702 is installed at the output end of the second motor 701. The drill bit 703 is installed inside the mounting block 702. The fixing assembly 8 includes a hydraulic cylinder 801 and a pressure plate 802. The hydraulic cylinder 801 is installed inside the fixing plate 601, and the pressure plate 802 is installed at the output end of the hydraulic cylinder 801.

[0031] Specifically, such as Figures 1 to 5As shown, adjusting component 3 is activated according to the position requirements of the machining hole. Electric slide rail 302 operates within the transverse groove 301, driving adjusting plate 303 to move laterally. Simultaneously, electric slide rail 304 drives sliding block 305 to move longitudinally on adjusting plate 303. Through the coordinated lateral and longitudinal movements, lowering component 4 and its connected subsequent components are adjusted to approximately above the hole to be machined on the circuit board. Electric push rod 401 in lowering component 4 is activated, pushing mounting bracket 402 downwards, thereby driving rotating component 5, fixing bracket 6, and drilling component 7 to move downwards as a whole. Upon approaching the circuit board, fixing component 8 begins to operate, hydraulic cylinder 801 extends, pushing pressure plate 802 downwards to further press and fix the circuit board. This, combined with adsorption component 9, achieves double fixing, ensuring the stability of the circuit board during drilling.

[0032] Furthermore, an adsorption assembly 9 is installed on the surface of the workbench 1. The adsorption assembly 9 includes an air chamber 901, an air hole 902 and a connecting pipe 903. The air chamber 901 is opened in the inner cavity of the workbench 1, the air holes 902 are opened at equal intervals on the surface of the workbench 1, and a connecting pipe 903 is opened on one side of the air hole 902.

[0033] Specifically, such as Figures 1 to 5 As shown, when holes need to be processed on the circuit board, the circuit board is first placed on the surface of the worktable 1. At this time, the adsorption component 9 starts to work, connecting to an external negative pressure device through the connecting pipe 903, so that a negative pressure is formed inside the air chamber 901, and then the circuit board is adsorbed through the equally spaced air holes 902, initially fixing the circuit board on the worktable 1 to prevent it from shifting during the processing.

[0034] Working principle: When processing holes in the circuit board, the board is first placed on the worktable 1. The adsorption component 9 is connected to an external negative pressure device through the connecting pipe 903, so that the air chamber 901 forms a negative pressure. The board is initially fixed through the air hole 902. In the adjustment component 3, the electric slide rail 1 302 drives the adjustment plate 303 to move laterally, and the electric slide rail 2 304 drives the sliding block 305 to move longitudinally, adjusting the lowering component 4 and subsequent components above the hole to be processed. If the drilling angle needs to be adjusted, the motor 1 504 of the rotating component 5 drives the rotating frame 503, which drives the rolling ball 501 to rotate in the mounting frame 402. The mounting rod 505 adjusts the fixing frame 6 and the drilling component 7 to the required angle. The electric push rod 401 pushes the mounting frame 402 down, bringing the relevant components closer to the board. The hydraulic cylinder 801 of the fixing component 8 pushes the pressure plate 802 to further press the board, achieving double fixing. The motor 2 701 drives the drill bit 703 to rotate at high speed, and the electric push rod 401 continues to move down to complete the drilling. After processing, all components are reset, the adsorption and fixing component 8 is released, and the substrate is removed.

[0035] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
