[0018] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] Please refer to Figure 1-2 As shown, a positioning device for improving the rounded corner burr of a PCB board comprises a device body 1, wherein the device body 1 is provided with a conveyor belt 4 for conveying a PCB board 2, a guide channel 3 for guiding the PCB board 2, and a lifting channel 5 connected with the guide channel 3, wherein the lifting channel 5 is provided with a lifting mechanism 6 for lifting the PCB board 2;

[0020] Four positioning grooves 7 are provided at the edge of the PCB board 2 , and the lifting mechanism 6 cooperates with the four positioning grooves 7 to lift the PCB board 2 for rounded corner grinding.

[0021] The present application first arranges the PCB board using a guide channel and then transports it to a lifting channel, and then uses a lifting mechanism to extend into four positioning grooves of the PCB board to lift it. Since the four sides of the board are positioned, the board is evenly stressed and stable during grinding, thereby solving the problem of burring. Furthermore, the present application is more convenient to operate and improves production efficiency.

[0022] In this embodiment, the lifting channel 5 is provided with a slope 8 and a plane 9 connected to the slope 8. First, the guide channel provided with the slope is used to transport the PCB boards one by one into the lifting channel, and then the conveyor belt is used to allow the rear PCB board to push the front board body to transition over the slope and enter the plane, and then the PCB board is positioned and lifted at the plane.

[0023] In this embodiment, the lifting channel 5 is provided with four concave cavities;

[0024] The lifting mechanism 6 includes a lifting portion 10 extending into the concave cavity, the end of the lifting portion 10 is U-shaped and can be matched with the positioning groove 7. The lifting portion 10 is provided with a connecting arm 11, and the connecting arm 11 is connected to the driving cylinder 12.

[0025] In order to improve stability and even force distribution, four lifting parts are driven simultaneously by one driving cylinder.

[0026] In this embodiment, a cross arm 13 is provided between two oppositely disposed connecting arms 11 , a driving arm 14 is provided between the two cross arms 13 , and the driving arm 14 is connected to the driving cylinder 12 .

[0027] In this embodiment, sliding grooves 15 for the connecting arms 11 to slide are provided on both sides of the device body 1 .

[0028] In this embodiment, the lifting channel 5 is provided with a micro switch 16 for sensing the PCB board 2. When the PCB board is pushed to the end of the plane and the micro switch is triggered, the conveyor belt stops working, and then the lifting mechanism works, so that the polishing device polishes the current PCB board. After polishing, the PCB board is put down for further transportation, and then the above action is repeated for the next PCB board, which can also ensure that the position of the lifting part is relative to the positioning groove.

[0029] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
