[0025] The following is a detailed description of a preferred embodiment of the present utility model in conjunction with the accompanying drawings.

[0026] Refer to Figures 1 to 4, a PCB gold-plated plug chamfering device provided in this embodiment is used to chamfer the end of a PCB gold-plated plug.

[0027] The chamfering device includes a workbench 1. Define the three directions perpendicular to each other in the space as the X direction, the Y direction, and the Z direction. A positioning and moving mechanism 2, a chamfering mechanism 3, and a dust suction mechanism 4 are provided on the workbench 1. The positioning and moving mechanism 2 is used to fix the PCB board to be chamfered and move the PCB board along the X direction. When the positioning and moving mechanism 2 drives the PCB board past the chamfering mechanism 3, the chamfering mechanism 3 performs chamfering operations on it, and the powder and dust generated during the chamfering process are processed by the dust suction mechanism 4. The mutual cooperation among the three mechanisms realizes the technical effects of automation and environmental protection.

[0028] Specifically, the positioning and moving mechanism 2 includes two guide rail bars 21 arranged at intervals along the Y direction on the workbench 1, and a fixture assembly 22 slidably arranged on the guide rail bars 21 and used to fix the PCB board.

[0029] Among them, the fixture assembly 22 includes a placement plate 221, and two first connectors 222 arranged at the bottom of the placement plate 221 and respectively slidably fitted on the two guide rail bars 21. The two first connectors 222 cover the outside of the guide rail bars 21 to form a stable connection and ensure the smoothness of the placement plate 221 during movement.

[0030] In addition, two positioning members 223 are arranged at intervals along the X direction on the top of the placement plate 221. One positioning member 223 is fixedly connected to the placement plate 221, and the other positioning member 223 is slidably connected to the placement plate 221 and can move along the X direction to approach or move away from one of the positioning members 223 to form a clamping space 224 for fixing the PCB board. The variability of the clamping space 224 can meet the positioning of PCB boards of different specifications.

[0031] Two guiding slot holes 2211 are arranged at intervals along the Y direction on the placement plate 221. Two sliders 2231 matching the guiding slot holes 2211 are arranged on the side of the other positioning member 223 away from the clamping space 224. Screw assemblies 2232 for fixing or releasing the positioning member 223 are respectively arranged on the two sliders 2231. Refer to Figure 2, in this embodiment, the screw assembly 2232 selects a combination of a wing nut and a screw. The screw vertically penetrates upward from the bottom of the slider 2231 into the connection hole on the slider 2231, and the screw extends beyond the upper end surface of the placement plate 221 to facilitate the connection between the wing nut and the screw. It is known that the head of the screw is fixedly connected to the bottom of the slider 2231. In this way, when the wing nut is manually tightened or loosened, the screw always remains fixed, and when the wing nut is tightened, the lower end surfaces of its two lugs abut against the upper surface of the placement plate 221, so that the positioning member 223 can be fixed, with a simple structure and convenient operation. By positioning the PCB board on the movable placement plate, the friction between the PCB board and the workbench surface is avoided, ensuring product quality; at the same time, one of the positioning members is set to be movable to be applicable to PCB boards of different specifications, improving the versatility of this device.

[0032] Further, the chamfering mechanism 3 is arranged on the workbench 1 surface on the Y - side of the positioning and moving mechanism 2 through a fixing plate, and includes a chamfering assembly 31 and a position - adjusting assembly 32. Among them, the chamfering assembly 31 is arranged on the position - adjusting assembly 32 to realize the adjustment of the angle and height of the chamfering assembly 31.

[0033] Specifically, the chamfering assembly 31 includes a tool 311 for chamfering the PCB board fixed on the fixture assembly 22, and a motor 312 for driving the tool 311 to rotate. The position - adjusting assembly 32 includes a lifting plate 321, a lead - screw module for driving the lifting plate 321 to move along the Z - direction, and an angle - adjusting module arranged on the lifting plate 321 for fixing and adjusting the angle of the motor 312.

[0034] Among them, the lead - screw module includes a lead - screw 322 arranged on the positive X - side of the lifting plate 321 and arranged along the Z - direction, a lead - screw nut 323 arranged on the lifting plate 321 and threadedly connected to the lead - screw 322, and a handwheel 324 for driving the lead - screw 322 to rotate around its central axis. That is, rotating the handwheel 324 forward and backward drives the lead - screw 322 to rotate, so that the lead - screw nut 323 connected to the lead - screw 322 moves up and down along the lead - screw 322, thereby realizing the lifting movement of the lifting plate 321.

[0035] Furthermore, the screw rod 322 is rotatably arranged on the workbench 1 through the positioning guide rail 325. The middle part of the positioning guide rail 325 is provided with a slide groove 3251 adapted to the screw rod nut 323 along the Z direction. The hand wheel 324 is connected to the screw rod 322 through the bearing 326. The bearing 326 is fixedly arranged on the top of the positioning guide rail 325. It can be understood that the lower end of the screw rod 322 can also be provided with a bearing to facilitate the stable rotation of the screw rod 322. In addition, a second connecting body 327 slidably connected to the positioning guide rail 325 is provided on the side of the lifting plate 321 facing the positioning guide rail 325. The positioning guide rail 325 is provided to provide a directional moving path for the screw rod nut 323 and the second connecting body 327, thereby ensuring the stability of the lifting process of the lifting plate 321.

[0036] Furthermore, the motor 312 is movably arranged on a side of the lifting plate 321 away from the screw module through the motor fixing plate 3121, and one end of the motor fixing plate 3121 away from the tool 311 is rotatably connected to the lifting plate 321 through the rotating shaft 3122. One end of the rotating shaft 3122 passes through the motor fixing plate 3121 to form a rivet joint, and the other end passes through the lifting plate 321 to form a rivet joint, so that the motor fixing plate 3121 can be connected to the lifting plate 321 without affecting the rotation of the motor fixing plate 3121.

[0037] One end of the motor fixing plate 3121 close to the tool 311 is slidably connected to the lifting plate 321 through a limiting guide 3123, and an arc-shaped slot 3211 is provided on the lifting plate 321 for the limiting guide 3123 to move; a bolt 3124 is threadedly connected to the limiting guide 3123, and when the bolt 3124 is locked on the limiting guide 3123, the end surface of the side facing the lifting plate 321 is pressed against the lifting plate 321. It can be understood that when the bolt 3124 is loosened, the angle of the tool 311 can be adjusted by moving the lower end of the motor fixing plate 3121 along the arc-shaped slot 3211, so that different chamfering effects can be obtained; in addition, a scale line (not marked in the figure) can be set on the arc-shaped slot 3211 to show the adjustment position of the tool 311.

[0038] Furthermore, the dust suction mechanism 4 has a dust suction pipe 41 which is arranged directly below the motor 312 and whose inlet faces the side of the tool 311. The dust suction pipe 41 is arranged on the workbench 1 along the Y direction through the positioning bracket 42, and a dust suction notch 411 is opened on the upper part of its inlet. The dust suction mechanism 4 also includes a dust shield 43 made of transparent material. The dust shield 43 is arranged on one end of the motor fixing plate 3121 close to the tool 311. Under the premise of not affecting the operator's line of sight, it can prevent the operator from touching the tool 311 to avoid safety accidents; in addition, the cooperation between the dust shield 43 and the dust suction pipe 41 can effectively eliminate powder dust in the working environment. The outlet side of the dust suction pipe 41 is connected to a vacuum cleaner, which is an existing device and will not be described here.

[0039] In summary, for the PCB gold-plated plug chamfering device provided by the present utility model, by setting a positioning and moving mechanism on the workbench to adapt to the fixing and moving of PCB boards of different specifications, avoiding friction between the PCB board and the workbench surface, it has a simple structure and a wide application range, while ensuring product quality; by setting a chamfering mechanism with adjustable angle and height to adapt to products with different chamfering requirements, improving the applicability and versatility of the chamfering device; by setting a dust suction mechanism, it can effectively eliminate powder dust in the working environment, and at the same time, the transparent dust shield does not affect the operator's line of sight and prevents the operator from touching the tool, so as to avoid safety accidents.
