[0022] The following is a further description of the utility model in conjunction with the accompanying drawings of the specification, but the utility model is not limited to the following embodiments. The diffuse reflection switch can be connected to the PLC control system to achieve operation. And there is no restriction on a specific model, and the diffuse reflection switch may not be set, and the overall operation can also be achieved. No special limitation is made, just providing a way.

[0023] Example 1

[0024] A positioning mechanism for heavy-loaded wool sticks, such as Figure 1-5As shown, it includes a guide assembly 1 and a guide wheel assembly 2; the guide wheel assembly 2 is fixed on the material cart 3, and the guide assembly 1 is set on the ground. The guide wheel assembly 2 is limited by the guide assembly 1 to achieve positioning of the material cart; the guide assembly 1 includes a guide seat 102, and the guide wheel assembly 2 includes a guide wheel 204. Positioning is achieved by placing the guide wheel 204 in a limiting groove in the middle of the guide seat 102.

[0025] The guide wheel assembly 2 also includes a guide wheel bracket 201, a tapered roller guide 202, and a pin 203. The guide wheel assembly 2 is fixed to the material cart 3 through the guide wheel bracket 201. The guide wheel 204 is set on the guide wheel bracket 201 through the pin 203 and the tapered roller guide 202. The pin 203 passes through the guide wheel bracket 201 and the guide wheel 204 and is connected to the tapered roller guide 202.

[0026] The tapered roller guide 202 is connected to the pin 203 via bolts.

[0027] The number of guide seats 102 is configured as required, and preferably two are provided.

[0028] Each guide seat 102 includes two guide blocks, which are arranged opposite to each other and have a limiting groove in the middle, and the limiting groove in the middle is used to place the guide wheel 204. In addition, at the limiting groove, the single-side spacing between each guide block and the guide wheel 204 is 4 mm.

[0029] After the two guide blocks are spliced, the top surface of the whole is V-shaped; the top surface of the guide block is an inclined surface, and the height of the inner side of the guide block is lower than the height of the outer side thereof.

[0030] The guide assembly 1 further includes a frame body 101 , and a guide seat 102 is disposed on the top surface of the frame body 101 .

[0031] An adjustment foot 103 is disposed at the bottom of the frame 101 .

[0032] During specific operation, the crystal rod trolley 3 is carried by the AGV trolley (existing equipment) to the loading position and moves horizontally from the side to the top of the guide assembly 2;

[0033] At this time, the AGV trolley (existing equipment) puts down the material cart 3, and the guide wheel 204 on the guide wheel assembly 2 at the bottom of the material cart 3 contacts and rolls with the inclined surface (V-shaped) of the guide block of the guide seat 102, and rolls into the limit groove in the middle of the guide block along the inclined surface by gravity to achieve positioning. The four limit grooves with inclined surface guides on the front and rear four guide seats 102 cooperate with the guide wheel 204 to achieve left and right direction positioning, meeting the grasping accuracy of the truss. The diffuse reflection switch 104 on the guide seat 102 detects that there is a material cart 3 on the positioning mechanism, feedbacks the signal, and the existing truss starts to move to grasp the crystal rod. When the AGV trolley (existing equipment) is abnormal and needs manual operation to load the material, the material cart 3 is manually pushed to the side of the positioning mechanism, and the guide assembly 1 and the guide wheel assembly 2 are displaced and pushed horizontally in the front and rear direction until the guide wheel 204 is directly above the guide seat 102, and then pushed forward, and the cone rod guide 202 contacts the side of the guide seat 102 and slides into the middle limit groove through the inclined surface guide to achieve positioning.

[0034] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
