[0029] A robot flexible workstation positioning device includes: a workpiece table 1, a mold changing and lifting assembly 2, a positioning assembly 3, and a sensing assembly 4.

[0030] In one embodiment, such as Figures 1 to 4 As shown, the mold changing lifting assembly 2 is installed at the bottom of the workpiece table 1, the positioning assembly 3 is installed on the workpiece table 1, and the sensing assembly 4 is installed on the workpiece table 1.

[0031] In one embodiment, such as Figures 1 to 4As shown, the mold changing and lifting assembly 2 has two sets and is installed symmetrically on the bottom of the workpiece table 1.

[0032] In one embodiment, such as Figures 1 to 4 As shown, the mold changing lifting assembly 2 includes: a lifting plate 21, a rolling assembly 22, a cylinder 23, a lifting fixing column 24, and a support column 25;

[0033] Two cylinders 23 are provided and fixedly installed on the bottom of the lifting plate 21 by several support columns 25; one end of the lifting fixing column 24 is fixedly connected to the end of the telescopic rod of the cylinder 23, and the other end passes through the lifting plate 21 and is fixedly connected to the bottom of the workpiece table 1; several rolling groups 22 are provided and fixedly installed on the lifting plate 21.

[0034] In one embodiment, such as Figures 1 to 4 As shown, the workpiece stage 1 is provided with through holes corresponding to the positions of the rolling group 22.

[0035] In one embodiment, such as Figures 1 to 4 As shown, the workpiece stage 1 has a fixed interface 26.

[0036] In one embodiment, such as Figures 1 to 4 As shown, the positioning component 3 includes a guide plate 31 and a limiting block 32;

[0037] The guide plate 31 is provided with two plates and is installed symmetrically on the workpiece table 1;

[0038] Two limiting blocks 32 are provided and are fixedly installed on the rear side of the workpiece stage 1.

[0041] Working principle: When this utility model is in operation, it is connected to external equipment. At this time, the cylinder 23 is in the retracted state, and the rolling assembly 22 extends through the through hole, so that the workpiece moves through the roller 222. At the same time, the guide plate 31 guides the workpiece, and the limiting block 32 ensures that the workpiece moves to the designated position. Meanwhile, the sensor 41 and the sensing plate 42 determine whether the position is in place. When the position is in place, the cylinder 23 works, extends and drives the lifting plate 21 to retract, so that the rolling assembly 22 retracts, and the workpiece is positioned for welding. When welding is completed, the cylinder 23 retracts and drives the rolling assembly 22 to extend, so that the workpiece is removed.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
