Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, specifically a PCB drilling positioning device. Background Technology

[0002] A PCB drilling positioning device is a device used for drilling and positioning on a PCB. It mainly consists of a drilling mechanism and a positioning clamping mechanism. It can ensure that the drilling position on the PCB is accurate and improve product quality. The drilling mechanism is generally composed of a three-axis drive mechanism and a drilling machine.

[0003] A search revealed that patent application number 202420631028.4 discloses a PCB drilling positioning device, comprising a body with four symmetrically arranged support rods fixedly mounted on the upper surface of the body. A support frame plate is mounted on the top of each support rod. Push rods are vertically fixedly mounted on the upper surface of the body at corresponding positions on both sides of the support frame plate. A clamping frame plate located above the support frame plate is fixedly connected to the top of each push rod. The bottom of the clamping frame plate has a positioning groove with an open front, the shape and size of which are adapted to the support frame plate. In this invention, the PCB is inserted into the positioning groove on the front of the clamping frame plate and placed on top of the support frame plate. The push rod moves downwards, causing the positioning groove on the clamping frame plate to clamp and position the edge of the PCB, ensuring a firm fixation of the PCB, preventing shaking and displacement, and ensuring drilling accuracy. This solves the problem that existing PCB drilling positioning methods using tape fixation easily cause the PCB to shake and shift due to the torque of the drill bit.

[0004] In the PCB manufacturing industry, stable clamping of the PCB board is crucial for ensuring the accuracy and efficiency of subsequent processing such as drilling. Currently, existing positioning operations generally use bolt fastening, requiring multiple bolts to work together for positioning. This method not only involves cumbersome procedures and is time-consuming, but frequent bolt removal and installation can also damage the PCB board surface, significantly reducing production efficiency. Furthermore, the cumulative effect of errors from multiple bolts makes it difficult to guarantee precise PCB board fixation, directly affecting the stability of drilling and processing quality.

[0005] Therefore, we propose a PCB drilling positioning device. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a PCB drilling positioning device, which solves the problem that existing devices are unable to stably and efficiently position PCB boards according to requirements.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a PCB drilling positioning device, including a base and a worktable on its top side, a board groove is provided at the center of the top of the worktable, a PCB board adapted to the specifications of the worktable is provided above the worktable, a pressure plate is provided inside the board groove, and a positioning hole is provided on the pressure plate.

[0008] The top of the workbench is fixedly equipped with a limiting frame located on the side of the board groove, and the bottom side of the workbench is provided with a positioning component. The positioning component is provided with a pressure strip located inside the limiting frame, and the pressure strip and the limiting frame are pressed together on the side of the PCB board.

[0009] As a preferred embodiment of this utility model, the limiting frame is disposed on the outer side of the four sides of the plate groove, and a guide groove that passes through the top side is provided at the center of the top side of the limiting frame, and a stop bar located at the bottom side of the guide groove is fixedly installed on the inner side wall of the limiting frame.

[0010] The guide groove allows the locking blocks on the positioning component to slide up and down within it, thus clamping the edge of the PCB board between the positioning component and the limiting frame, achieving a stable clamping effect.

[0011] As a preferred embodiment of this utility model, the positioning component includes a hydraulic cylinder group fixedly installed at the center of the bottom of the workbench, and a support plate is fixedly connected to the bottom end of the output shaft of the hydraulic cylinder group, and four sets of opposing support columns are fixedly installed on the support plate.

[0012] The support plate is designed to be driven by a hydraulic cylinder group to move four sets of pillars downward in a synchronized manner, and to efficiently clamp the sides of the PCB board from four directions. The operation is simple and ensures the stability and synchronization of the clamping of the PCB board in four positions, thus maintaining the positioning effect.

[0013] As a preferred embodiment of this utility model, the workbench is provided with four sets of support holes located around the plate groove, the support column is movably fitted inside the support holes, and the top of the support column is fixedly connected with a locking block.

[0014] The support column facilitates the upward and downward movement of the top locking block and pressure bar, achieving a stable clamping effect on the PCB board from the top.

[0015] As a preferred embodiment of this utility model, a spring column is provided on the outer side of the support column between the locking block and the top surface of the workbench. The locking block is locked in the guide groove, and a pressure strip is fixedly connected to the front end of the locking block above the abutment bar.

[0016] The spring post can apply a reverse force to the clamping block and pressure bar during their up-and-down sliding motion, thereby achieving a clamping effect on the PCB board between the pressure bar and the abutment bar.

[0017] As a preferred embodiment of this utility model, elastic cotton strips are glued between the bottom side of the pressure strip and the top side of the abutment strip;

[0018] Both the upper and lower sets of elastic cotton strips are in contact with the edges of the PCB board, ensuring the clamping effect while also providing appropriate protection for the edges of the PCB board.

[0019] This utility model provides a PCB drilling positioning device. It has the following beneficial effects:

[0020] This PCB drilling positioning device, through the setting of the worktable and its positioning components, can use a hydraulic cylinder group to uniformly drive the support plate to move down and simultaneously drive the support column to slide up and down, so as to adjust the position of the pressure bar and stably clamp the PCB board from the upper and lower parts of the side. At the same time, no manual drive is required; only the drive of the hydraulic cylinder group can achieve uniform positioning of four sets of perimeters and ensure the positioning effect. This solves the problem that existing devices are unable to stably and efficiently position the PCB board according to the requirements. Attached Figure Description

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.

[0027] Please see Figure 1-4This utility model provides a technical solution: a PCB drilling positioning device, including a base 1 and a worktable 2 on its top side. A board groove 21 is opened at the center of the top of the worktable 2. A PCB board 4 adapted to the specifications of the worktable 2 is arranged above the worktable 2. A pressure plate 22 is arranged inside the board groove 21, and a positioning hole 23 is opened on the pressure plate 22. A limiting frame 5 located on the side of the board groove 21 is fixedly installed on the top of the worktable 2. A positioning component 3 is arranged on the bottom side of the worktable 2. A pressure strip 35 located inside the limiting frame 5 is arranged in the positioning component 3, and the pressure strip 35 is pressed between the limiting frame 5 and the side of the PCB board 4.

[0028] The PCB drilling positioning device, through the setting of the worktable 2 and the positioning components 3 on it, can use the hydraulic cylinder group 31 to uniformly drive the support plate 32 to move down and simultaneously drive the support column 33 to slide up and down, so as to adjust the position of the pressure bar 35 and stably clamp the PCB board 4 from the upper and lower parts of the side. At the same time, no manual driving is required. Only the driving of the hydraulic cylinder group 31 can achieve uniform positioning of four sets of perimeters and ensure the positioning effect. It solves the problem that existing devices are difficult to stably and efficiently position the PCB board 4 according to the requirements.

[0029] Example 2:

[0030] The limiting frame 5 is set on the outer side of the four sides of the plate groove 21. A guide groove 51 is opened at the center of the top side of the limiting frame 5, and a stop bar 52 located at the bottom side of the guide groove 51 is fixedly installed on the inner side wall of the limiting frame 5. The guide groove 51 facilitates the sliding of the locking block 34 on the positioning component 3, so as to clamp the edge of the PCB board 4 between the positioning component 3 and the limiting frame 5, thereby achieving a stable clamping effect.

[0031] The positioning component 3 includes a hydraulic cylinder group 31 fixedly installed at the center of the bottom of the workbench 2. The bottom end of the output shaft of the hydraulic cylinder group 31 is fixedly connected to a support plate 32, and four sets of opposing support columns 33 are fixedly installed on the support plate 32. The support plate 32 is configured to drive the four sets of support columns 33 to move down synchronously by the hydraulic cylinder group 31, and to efficiently clamp the side of the PCB board 4 from four directions. The operation is simple and ensures the stability and synchronization of the clamping of the PCB board 4 at the four positions, thus maintaining the positioning effect.

[0032] The workbench 2 has four sets of support holes 24 located around the board groove 21. The support column 33 is movably fitted inside the support hole 24, and the top of the support column 33 is fixedly connected to the locking block 34. The support column 33 is designed to facilitate the sliding of the locking block 34 and the pressure strip 35 on its top, and to achieve a stable clamping effect on the PCB board 4 from the top.

[0033] A spring post 36 is provided on the outer side of the support column 33 between the clamping block 34 and the top surface of the worktable 2. The clamping block 34 is clamped in the guide groove 51, and the front end of the clamping block 34 is fixedly connected to a pressure bar 35 provided above the abutment bar 52. The spring post 36 can apply a reverse force to the clamping block 34 and the pressure bar 35 during their up and down sliding, thereby achieving the clamping effect on the PCB board 4 between the pressure bar 35 and the abutment bar 52.

[0034] Elastic cotton strips are glued between the bottom side of the pressure strip 35 and the top side of the abutment strip 52; the upper and lower sets of elastic cotton strips are in contact with the edge of the PCB board 4, ensuring the clamping effect while also providing corresponding protection for the edge of the PCB board 4.

[0035] The working principle and usage process of this utility model are as follows: When the device is required to work, the hydraulic cylinder group 31 at the bottom of the workbench 2 drives the support plate 32 to move down, and at the same time drives the four sets of support columns 33 and the pressure strips 35 on them to move down synchronously, positioning and pressing the edge of the PCB board 4 between it and the pressure strip 52, ensuring the positioning effect of the PCB board 4. At the same time, the operation is simple and can accurately position and clamp the PCB board 4 from four sides, solving the problem that existing devices are difficult to accurately position the PCB board 4 according to the requirements and to efficiently drill holes.
