Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically a PCB board drilling structure that is easy to position. Background Technology

[0002] In today's electronic equipment manufacturing industry, the drilling process for PCBs (Printed Circuit Boards) is particularly crucial. With the rapid development of electronic technology, PCB designs are becoming increasingly complex, leading to ever-increasing demands for drilling precision and efficiency. To meet these high standards, advanced technologies and equipment must be employed in the manufacturing process to ensure drilling accuracy and speed. This involves not only the precision and stability of the drilling equipment but also the selection of drill bits, optimization of drilling parameters, and quality control throughout the drilling process. Only through continuous technological innovation and process improvement can a company maintain a leading position in the fierce market competition and meet customers' needs for high-performance electronic devices.

[0003] Traditional PCB drilling methods often rely on manual operation or rudimentary mechanical devices. Manual drilling is not only inefficient but also struggles to guarantee high precision in drilling position, easily leading to deviations. This severely impacts subsequent electronic component installation and circuit connections, resulting in increased product defect rates. Furthermore, some simple mechanical devices lack precision and convenience in positioning PCBs of different sizes and shapes during drilling, potentially causing PCB displacement during the process. This fails to meet the demands of large-scale, diversified production. Additionally, adjusting the drilling position using traditional drilling equipment is complex and inflexible, significantly reducing production efficiency. Therefore, to adapt to the rapid development of modern electronics manufacturing, there is an urgent need for a PCB drilling structure that facilitates positioning, effectively addressing the problems of traditional drilling methods, improving the precision, efficiency, and stability of PCB drilling, thereby enhancing the overall quality and production efficiency of electronic products. Utility Model Content

[0004] The purpose of this invention is to provide a PCB board drilling structure that is easy to position, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCB board drilling structure for easy positioning, comprising a support platform, a drilling lateral adjustment part, and a drilling longitudinal positioning part. A support leg is fixedly installed on the bottom outer wall of the support platform, and a support pad is fixedly installed on the bottom of the support leg. The drilling lateral adjustment part is located at the top of the support platform, and the drilling longitudinal positioning part is located at the bottom of the drilling lateral adjustment part.

[0006] Preferably, the lateral adjustment part for drilling specifically includes: a fixed base plate, fixedly installed on the outer walls of both sides of the support platform; a support block, fixedly installed on the top outer wall of the fixed base plate; a textured support block, equidistantly fixedly installed on the top outer wall of the support platform; a positioning bolt, fixedly installed on the top outer wall of the support platform; and a PCB board, disposed on top of the textured support block.

[0007] Preferably, a limiting block one and a limiting block two are fixedly installed on the outer wall of the support block, and a guide slide rod is fixedly connected between the limiting block one and the limiting block two. A motor mounting bracket is fixedly installed on the outer wall of the limiting block one, and a motor is fixedly installed inside the motor mounting bracket. The motor serves as a power source and cooperates with components such as the threaded rotating rod. For example, in the drilling lateral adjustment section, the motor drives the threaded rotating rod to rotate. The threaded rotating rod is connected to the threaded moving block through a threaded connecting sleeve, allowing the threaded moving block to move laterally along the guide slide rod. In this way, the drilling machine installed on subsequent components can achieve position adjustment in the lateral direction and locate the specific lateral point on the PCB board where the hole needs to be drilled, effectively avoiding positional deviations that may occur with manual adjustment and ensuring the accuracy of the drilling position.

[0008] Preferably, the output end of the motor is fixedly connected to a threaded rotating rod, the other end of which movably passes through one side of the outer wall of the first limiting block and extends to the other side of the outer wall of the first limiting block. The other end of the threaded rotating rod is rotatably connected to the outer wall of the second limiting block. A sliding block is movably sleeved on the outer wall of the guide slide rod. A threaded moving block is fixedly installed on the top of the sliding block. A threaded connecting sleeve is fixedly installed on the outer wall of the threaded moving block. The threaded moving block is threadedly connected to the threaded rotating rod through the threaded connecting sleeve.

[0009] Preferably, the longitudinal positioning part for drilling specifically includes: a longitudinal slide rail, fixedly installed on the bottom outer wall of the sliding block; the outer wall of the longitudinal slide rail has an opening, a motor mounting bracket is fixedly installed on the outer wall of the longitudinal slide rail, a drive motor is fixedly installed inside the motor mounting bracket, and a threaded screw is fixedly connected to the output end of the drive motor. The drive motor controls the rotation of the threaded screw, thereby driving the slider to move longitudinally on the longitudinal slide rail. This allows the drilling machine installed on the bottom connecting block of the slider to achieve positioning in the longitudinal direction, accurately meeting the drilling requirements of different longitudinal positions on the PCB board, effectively improving the accuracy of the drilling position, reducing the risk of drilling deviation or damage to the PCB board due to inaccurate longitudinal positioning, and enabling the drilling machine to flexibly and quickly switch and position in both the horizontal and vertical dimensions through the coordinated work of the drive motor and other components, greatly improving the working efficiency of the entire PCB board drilling structure and adapting to various PCB board processing tasks with different drilling layouts and requirements.

[0010] Preferably, the other end of the threaded screw extends into the interior of the longitudinal slide rail through a through-hole, and the other end of the threaded screw is rotatably connected to the inner wall of the longitudinal slide rail. A slider is slidably connected inside the longitudinal slide rail, and a threaded hole is provided on the slider. The slider is threadedly connected to the threaded screw through the threaded hole, and a connecting block is fixedly installed on the bottom outer wall of the slider.

[0011] Preferably, a mounting plate is fixedly installed on the bottom outer wall of the connecting block. The mounting plate has a mounting groove and a sliding hole. An electric telescopic rod is fixedly installed inside the mounting groove. A lifting plate is fixedly connected to the telescopic end of the electric telescopic rod. The lifting plate has a drilling machine mounting groove. A drilling machine is fixedly installed inside the drilling machine mounting groove. The electric telescopic rod can control the lifting height of the drilling machine. During the drilling process, it can be adjusted according to the thickness of the PCB board and the required drilling depth, thereby ensuring the consistency of the drilling depth and avoiding damage to the PCB board due to drilling too deep or too shallow, effectively improving the drilling accuracy.

[0012] Preferably, the lifting plate has a sliding rod groove, and a sliding rod is slidably connected inside the sliding rod groove. A limit plate is fixedly installed at one end of the sliding rod, and a positioning block is fixedly installed at the other end of the sliding rod. A spring connecting block is fixedly sleeved on the outer wall of the sliding rod, and a spring is movably sleeved on the outer wall of the sliding rod. One end of the spring is fixedly connected to the spring connecting block, and the other end of the spring is fixedly connected to the lifting plate.

[0013] This invention provides a PCB board drilling structure that facilitates positioning. It offers the following advantages:

[0014] (1) The positioning bolts set on the top outer wall of the support platform can provide an initial positioning reference for the placement of PCB boards, ensuring that the PCB boards are in a relative position before horizontal adjustment, which helps to carry out the subsequent drilling operation accurately. For example, when drilling PCB boards in batches, the positioning bolts can make the starting position of each PCB board consistent, improving the consistency and accuracy of the drilling position. The textured support blocks are fixedly installed at equal intervals on the top outer wall of the support platform, which can provide a stable support surface for the PCB boards, preventing the PCB boards from shaking or shifting due to force during the drilling process, ensuring the quality of drilling. Moreover, the fixed base plate and support blocks further enhance the stability of the entire structure, so that horizontal adjustment and other related operations can be carried out smoothly.

[0015] (2) This utility model drives the screw rod to rotate by a drive motor, so that the slider connected to the screw rod can slide stably along the longitudinal slide rail, thereby accurately controlling the position of the drilling machine in the longitudinal direction, meeting the needs of drilling at different longitudinal positions of the PCB board, ensuring the accuracy of the drilling position, helping to improve the quality of PCB board drilling, and avoiding problems such as drilling deviation due to inaccurate positioning. The structure of the electric telescopic rod allows the drilling machine to adjust its height in the up and down direction. When facing PCB boards of different thicknesses or requiring different drilling depths, the height of the drilling machine can be adjusted. The slide rod, spring and positioning block can press down and stabilize the PCB board to prevent deviation during drilling. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1:

[0024] A preferred embodiment of the PCB board drilling structure for easy positioning provided by this utility model is, for example... Figure 1-4 As shown: A PCB board drilling structure for easy positioning includes a support platform 1, a drilling lateral adjustment part 3, and a drilling longitudinal positioning part 4. The support platform 1 has a support leg 2 fixedly installed on its bottom outer wall, and a support pad is fixedly installed on the bottom of the support leg 2. The drilling lateral adjustment part 3 is located at the top of the support platform 1. The drilling longitudinal positioning part 4 is located at the bottom of the drilling lateral adjustment part 3.

[0025] The drilling lateral adjustment part 3 specifically includes: a fixed base plate 3113, which is fixedly installed on both outer walls of the support platform 1; a support block 314, which is fixedly installed on the top outer wall of the fixed base plate 3113; a textured support block 312, which is fixedly installed at equal intervals on the top outer wall of the support platform 1; a positioning bolt 311, which is fixedly installed on the top outer wall of the support platform 1; and a PCB board 313, which is set on top of the textured support block 312.

[0026] Limiting block one 314 and limiting block two 315 are fixedly installed on the outer wall of the support block 314 respectively. A guide slide rod 316 is fixedly connected between the limiting block one 314 and the limiting block two 315. A motor fixing frame is fixedly installed on the outer wall of the limiting block one 314. A motor 3111 is fixedly installed inside the motor fixing frame.

[0027] A threaded rotating rod 3112 is fixedly connected to the output end of the motor 3111. The other end of the threaded rotating rod 3112 movably passes through one side of the outer wall of the first limiting block 314 and extends to the other side of the outer wall of the first limiting block 314. The other end of the threaded rotating rod 3112 is rotatably connected to the outer wall of the second limiting block 315. A sliding block 317 is movably sleeved on the outer wall of the guide slide rod 316. A threaded moving block 318 is fixedly installed on the top of the sliding block 317. A threaded connecting sleeve 319 is fixedly installed on the outer wall of the threaded moving block 318. The threaded moving block 318 is threadedly connected to the threaded rotating rod 3112 through the threaded connecting sleeve 319.

[0028] In this embodiment, the motor 3111 starts and drives the threaded rotating rod 3112 to rotate. Since the threaded moving block 318 is threadedly connected to the threaded rotating rod 3112 through the threaded connecting sleeve 319, and the sliding block 317 is sleeved on the guide slide rod 316, during the rotation of the threaded rotating rod 3112, the threaded moving block 318 will drive the sliding block 317 to move laterally along the guide slide rod 316, thereby realizing the position adjustment of the drilling machine 419 installed on the drilling longitudinal positioning part 4 in the lateral direction of the PCB board 313. This can provide an initial positioning reference for the placement of the PCB board 313, ensuring that the PCB board 313 is in a relative position before the lateral adjustment, which helps to carry out the subsequent drilling operation accurately.

[0029] Example 2:

[0030] Based on Embodiment 1, a preferred embodiment of the PCB board 313 drilling structure for easy positioning provided by this utility model is, for example... Figure 1-4 As shown: The drilling longitudinal positioning part 4 specifically includes: a longitudinal slide rail 411, which is fixedly installed on the bottom outer wall of the sliding block 317; the outer wall of the longitudinal slide rail 411 has an opening, a motor fixing bracket is fixedly installed on the outer wall of the longitudinal slide rail 411, a drive motor 412 is fixedly installed inside the motor fixing bracket, and a threaded screw 4116 is fixedly connected to the output end of the drive motor 412.

[0031] The other end of the threaded screw 4116 extends into the interior of the longitudinal slide rail 411 through a through-hole. The other end of the threaded screw 4116 is rotatably connected to the inner wall of the longitudinal slide rail 411. A slider 413 is slidably connected inside the longitudinal slide rail 411. A threaded hole is provided on the slider 413. The slider 413 is threadedly connected to the threaded screw 4116 through the threaded hole. A connecting block 414 is fixedly installed on the bottom outer wall of the slider 413.

[0032] A mounting plate 416 is fixedly installed on the bottom outer wall of the connecting block 414. The mounting plate 416 has a mounting groove and a sliding hole 417. An electric telescopic rod 415 is fixedly installed inside the mounting groove. A lifting plate 418 is fixedly connected to the telescopic end of the electric telescopic rod 415. A drilling machine mounting groove is provided on the lifting plate 418. A drilling machine 419 is fixedly installed inside the drilling machine mounting groove.

[0033] A sliding rod groove is provided on the lifting plate 418, and a sliding rod 4111 is slidably connected inside the sliding rod groove. A limit plate 4112 is fixedly installed at one end of the sliding rod 4111, and a positioning block 4113 is fixedly installed at the other end of the sliding rod 4111. A spring connecting block 4114 is fixedly sleeved on the outer wall of the sliding rod 4111, and a spring 4115 is movably sleeved on the outer wall of the sliding rod 4111. One end of the spring 4115 is fixedly connected to the spring connecting block 4114, and the other end of the spring 4115 is fixedly connected to the lifting plate 418.

[0034] In this embodiment, the drive motor 412 starts, driving the threaded screw 4116 to rotate. The slider 413 is threadedly connected to the threaded screw 4116 through a threaded hole and slides within the longitudinal slide rail 411. When the threaded screw 4116 rotates, the slider 413 moves longitudinally along the longitudinal slide rail 411, thereby driving the connecting block 414, the mounting plate 416, and the drilling machine 419 to move in the longitudinal direction, realizing the position adjustment of the drilling machine 419 in the longitudinal direction of the PCB board 313. When the drilling machine 419 reaches above the predetermined drilling position, the electric telescopic rod 415 starts, and its telescopic end pushes the lifting plate 418 downward, driving the drilling machine 419 closer to the PCB board 313 to perform drilling operations. This allows the drilling machine 419 to achieve height adjustment in the vertical direction. When facing PCB boards 313 of different thicknesses or when different drilling depths are required, the height of the drilling machine can be adjusted. The slide rod, spring, and positioning block can press down and stabilize the PCB board 313 to prevent deviation during drilling.

[0035] Working principle: First, the PCB board 313 is placed on top of the textured support block 312 and initially positioned using the positioning bolt 311. When the drilling lateral adjustment part 3 is working, the motor 3111 starts, driving the threaded rotating rod 3112 to rotate. Since the threaded moving block 318 is threadedly connected to the threaded rotating rod 3112 through the threaded connecting sleeve 319, and the sliding block 317 is sleeved on the guide slide rod 316, during the rotation of the threaded rotating rod 3112, the threaded moving block 318 will drive the sliding block 317 to move laterally along the guide slide rod 316, thereby realizing the adjustment of the position of the drilling machine 419 installed on the drilling longitudinal positioning part 4 in the lateral direction of the PCB board 313. When the drilling longitudinal positioning part 4 is working, the drive motor 412 starts, driving the threaded screw 4116 to rotate. The slider 413 is threadedly connected to the threaded screw 4116 through the threaded hole and slides within the longitudinal slide rail 411. When the lead screw 4116 rotates, the slider 413 moves longitudinally along the longitudinal slide rail 411, thereby driving the connecting block 414, mounting plate 416, and drilling machine 419 to move in the longitudinal direction, realizing the position adjustment of the drilling machine 419 in the longitudinal direction of the PCB board 313. When the drilling machine 419 reaches above the predetermined drilling position, the electric telescopic rod 415 is activated, and its telescopic end pushes the lifting plate 418 downward, driving the drilling machine 419 closer to the PCB board 313 to perform drilling operations. During this process, the slide rod 4111 slides in the slide rod groove of the lifting plate 418, and the spring 4115 plays a buffering role. When drilling is completed, the electric telescopic rod 415 retracts, and the lifting plate 418 rises, ready for the next drilling operation. Through the coordinated work of the drilling lateral adjustment part 3 and the drilling longitudinal positioning part 4, the drilling positioning of the PCB board 313 can be accurately performed and the drilling operation can be completed.
