[0024] The working principle of the rotating mechanism 2 is: when rotating, the rotating motor 23 is started, and the rotating gear 24 is driven to rotate by the rotating motor 23, so that the rotating gear 24 drives the rotating gear ring 21 meshing with it to rotate, thereby realizing the rotation of the edge grinding turntable 12, thereby driving the PCB board on the edge grinding turntable 12 to rotate, which is convenient for the subsequent edge grinding of the four sides of the PCB board.

[0025] As a further solution, a pair of clamping mechanisms 4 are also installed at the upper end of the edge grinding table 1, and the clamping mechanism 4 includes a clamping seat 41 installed on the edge grinding table 1, and a clamping electric push rod 42 is installed on the clamping seat 41. The telescopic end of the clamping electric push rod 42 passes through the clamping seat 41 and is fixed with a clamping push plate 43. A clamping guide rod 44 is also slidably inserted on the clamping seat 41, and the end of the clamping guide rod 44 is fixedly connected to the clamping push plate 43. In this embodiment, a pair of the clamping mechanisms 4 are respectively installed on the front and rear sides of the edge grinding table 1.

[0026] The working principle of the clamping mechanism 4 is: when edge grinding is required, the clamping electric push rods 42 on the front and rear sides extend to push the clamping push plates 43 on both sides closer to each other, so that the PCB board is clamped by the clamping push plates 43 on both sides, which facilitates the edge grinding work.

[0027] As a further solution, an edge grinding assembly is further installed at the lower end of the movable slide 14, and the edge grinding assembly includes an adjustment mechanism 5 installed at the lower end of the movable slide 14 and an edge grinding mechanism 3 installed at the lower end of the adjustment mechanism 5;

[0028] The adjusting mechanism 5 includes a pair of adjusting seats 51 installed at the lower end of the movable slide 14, an adjusting screw 53 is rotatably installed in the adjusting seat 51, and an adjusting motor 52 is also installed at the end of the adjusting seat 51, and the output end of the adjusting motor 52 is drivingly connected to the shaft end of the adjusting screw 53; a pair of adjusting slides 54 are also slidably installed at the lower end of the movable slide 14 through a slide rail, and the adjusting slides 54 are threadedly mounted on the adjusting screw 53. In this embodiment, the left and right sides of the adjusting screw 53 have opposite thread rotation directions, and the pair of adjusting slides 54 are distributed on the left and right sides of the adjusting screw 53.

[0029] As a further solution, the edge grinding mechanism 3 includes an edge grinding seat 31 installed at the lower end of the adjusting slide 54, and an edge grinding roller 32 is rotatably installed at the lower end of the edge grinding seat 31. An edge grinding motor 33 is also installed at the upper end of the edge grinding seat 31, and the output end of the edge grinding motor 33 is drivingly connected to the shaft end of the edge grinding roller 32.

[0030] The working principle of the edge grinding assembly is: when adjusting, the adjusting motor 52 is started, and the adjusting screw 53 is driven to rotate by the adjusting motor 52, so that the adjusting slide 54 threadedly mounted on the adjusting screw 53 moves accordingly, so that the edge grinding rollers 32 on both sides are close to the PCB board, so as to facilitate the edge grinding of PCB boards of different sizes;

[0031] When edge grinding: the edge grinding motor 52 is started, and the edge grinding roller 32 is driven to rotate by the edge grinding motor 52, so that the edge grinding process can be performed on the position of the PCB board.

[0032] Working principle of the utility model: When in use, first place the PCB board to be processed on the edge grinding turntable 12, then start the adjustment motor 52, drive the adjustment screw 52 to rotate through the adjustment motor 52, and then drive the edge grinding rollers 32 to approach each other through the adjustment slides 54 on both sides, so as to position the PCB board and move it to the middle position of the edge grinding turntable 12;

[0033] Subsequently, the clamping electric push rods 42 on both sides push the clamping push plates 43 on both sides to approach each other, thereby clamping the PCB board. Subsequently, the edge grinding motor 52 is started, and the edge grinding roller 32 is driven to rotate by the edge grinding motor 52 to perform the grinding work. At the same time, the rodless cylinder 13 drives the moving slide 14 to move back and forth, thereby completing the edge grinding work on both sides of the PCB board at the same time.

[0034] After completing the edging work on the two sides, the clamping mechanism 4 releases the PCB board, and the edging roller 32 is reset. Subsequently, the rotating motor 23 is started, and the rotating gear 24 is driven by the rotating motor 23 to rotate, thereby realizing the rotation of the rotating gear ring 21, and then driving the edging turntable 12 to rotate. After the edging turntable 12 rotates 90 degrees, it stops rotating. Then, the above operation is repeated to perform edging operations on the other two sides. The edging work on all sides of the PCB board can be achieved without adding additional edging devices, which can effectively reduce production costs and better meet usage requirements.
