[0002] A dispensing machine, also known as a glue coating machine, a glue dropping machine, a glue injecting machine, a potting machine, etc., is a special automated machine for controlling fluids and dripping or coating the fluids on the surface or inside of products. It can achieve three-dimensional and four-dimensional path dispensing, precise positioning, accurate glue control, no wire drawing, no glue leakage and no glue dripping.

[0003] When the existing dispensing machine is working, it requires workers to place the workpiece at the corresponding position at the bottom of the dispensing machine, fix it, then perform dispensing through the dispensing machine and take it down for blanking. This process requires a large number of operations by workers, and the automation degree of the dispensing machine is relatively low, which is very inconvenient.

[0004] Therefore, we propose a positioning mechanism and its automatic dispensing. Content of the Utility Model

The lead screw is threadedly connected to the inner wall of the threaded hole. A clamping plate is fixedly connected to the outer wall of one side of the sliding rod.

[0013] Further, a plurality of rotation grooves arranged linearly are formed in the outer walls of the opposite sides of the two limiting plates. A ball is rotationally connected to the inner wall of the rotation groove.

[0014] Further, a limiting sliding groove is formed in the outer wall of the clamping plate away from the sliding rod.
