[0045] Under normal dispensing conditions, the three-axis drive mechanism drives the valve body connected to the glue supply cylinder to move above the product to be dispensed. At the same time, the glue supply cylinder supplies glue to the valve body, and the valve body accurately and quantitatively dispenses glue, realizing continuous dispensing of the product.

[0046] When the glue valve needs to be replaced after being used for a period of time, the first movable part and the second movable part on the clamping cylinder are moved away from each other, thereby loosening the glue valve to be replaced;

[0047] Then, the three-axis mechanism drives the base plate with the gripper cylinder to move to the vicinity of a new glue valve, so that the positioning pin installed on the base plate is at the same height as the positioning hole on the new glue valve. The three-axis mechanism drives the base plate to move toward the new glue valve until the positioning pin is embedded in the positioning hole. At this time, the glue valve is positioned in one direction.

[0048] The two clamping blocks are then driven toward each other by the clamping cylinder until they come into contact with the support plate on the valve, thereby clamping and installing the new valve. At the same time, the centering clamping of the two clamping blocks moving toward each other enables the positioning of the valve in the other direction, thereby maintaining the consistency of the valve position after multiple replacements, thereby ensuring the accuracy of dispensing. The entire process does not require manual labor, saving manpower and time, and avoiding manual operation errors.

[0049] When the glue supply cylinder is supplying glue to the valve body, high-pressure gas is injected into the glue supply cylinder through the air inlet on the top of the glue supply cylinder, pushing the glue liquid in the glue supply cylinder to flow toward the valve body;

[0050] When the glue in the glue supply cylinder is used up, the air injection stops and the valve body stops dispensing glue, and the air nozzle moves upward with the support frame and separates from the air inlet on the upper surface of the glue supply cylinder;

[0051] The air nozzle moves downward with the support frame and is connected to the air inlet on the upper surface of the glue supply cylinder. Air is ventilated into the glue supply cylinder through the air inlet to improve the fluidity of the glue during the glue supply process to the valve body. The glue in the glue supply cylinder flows toward the glue outlet channel under the action of gas pressure.

[0052] When the automatic loading and unloading mechanism of the above-mentioned dispensing unit is adopted, it can realize the automatic clamping and installation of the glue valve and the automatic disassembly of the glue valve through the telescopic movement of the two clamping blocks, thereby facilitating the fully automatic replacement operation of the glue valve, improving the automation level and processing efficiency of the entire dispensing process, and also automatically realizing the loading and unloading between the ventilation component and the new and old glue supply cylinders on the basis of ventilating the glue supply cylinder to improve the fluidity of the glue in the process of supplying glue to the valve body, further improving the automation level and operation stability of the entire continuous dispensing process; further, through the cooperation between the locating pin and the locating hole, the position of the glue valve can be further calibrated before the glue valve is clamped and loaded, thereby ensuring the position accuracy of the glue valve after clamping, thereby ensuring the accuracy of dispensing.

Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly.
