[0034] The positioning device provided in the present application can move the sprayed workpiece along the X-axis direction or the Y-direction through the first driving member and the second driving member during the spraying process until the edge of the sprayed workpiece contacts the first positioning block and the second positioning block. When the x-axis distance and the y-axis distance meet the system preset values, it indicates that the positioning is accurate. This can improve the positioning accuracy and positioning stability of the sprayed workpiece, and avoid the phenomenon in the related art that the sprayed workpiece is scrapped due to unstable and inaccurate positioning of the sprayed workpiece, resulting in incomplete processing of the outer edge.

[0035] In some embodiments, the positioning panel is rectangular and placed horizontally, the driving direction of the first driving member is along the X-axis direction, and the driving direction of the second driving member is along the Y-direction.

[0036] In some embodiments, the cross section of the connecting rod 5 is an isosceles trapezoid, the shape of the limiting groove 6 matches the isosceles trapezoid connecting rod 5, the opening of the limiting groove 6 is located at the shortest side of the isosceles trapezoid, and the setting of the isosceles trapezoid allows the connecting rod 5 to be stably restricted to slide in the limiting groove 6, and the opening of the limiting groove 6 is used to connect the first driving member 2 and the second driving member.

The distance sensor 11 senses the X-axis distance and the Y-axis distance of the sprayed workpiece on the positioning panel. When the x-axis distance and the y-axis distance meet the system preset values, it indicates that the positioning is accurate. Then the positioning controller controls the switch of the positioning panel 1 to be in the on state, so that the sprayed workpiece is stably positioned on the positioning panel 1. If it is necessary to process sprayed workpieces of different sizes, the first driving member 2 and the second driving member move with a certain amplitude, so that the first positioning block and the second positioning block limit the sprayed workpiece to the center position of the positioning panel 1, which is convenient for switching the positioning processing of sprayed workpieces of different sizes.

[0046] The spraying equipment provided in the present application can move the sprayed workpiece along the X-axis direction or the Y-direction through the first driving member and the second driving member during the spraying process until the edge of the sprayed workpiece contacts the first positioning block and the second positioning block.
