Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-3 The utility model provides a technical solution: a multi-channel dispensing controller, comprising: a chassis 1, the chassis 1 is provided with an air inlet, and external clean gas is connected to the dispensing controller through the air inlet;

[0028] Four pressure-stabilizing gas tanks 2 are provided in the chassis 1 , four negative pressure regulating valves 13 are provided on the side wall of the chassis 1 , and the air inlet is connected to the four pressure-stabilizing gas tanks 2 and the four negative pressure regulating valves 13 through air ducts.

[0029] The pressure-stabilizing gas storage tank 2 stores gas and provides stable gas pressure for the glue supply equipment. Each pressure-stabilizing gas storage tank 2 is connected to two positive pressure regulating valves 4 through a pipeline. The positive pressure regulating valves 4 are arranged on the side wall of the chassis 1;

[0030] The positive pressure regulating valve 4 is also connected to the electromagnetic valve 12, which provides positive pressure gas to the glue supply equipment. The positive pressure regulating valve 4 is provided with an adjusting knob, which adjusts the positive pressure of the glue supply gas outlet 3.

[0031] The solenoid valve 12 controls the connection mode of the gas circuit. The solenoid valve 12 is a three-way structure. It can connect the positive pressure regulating valve 4 and the glue supply gas circuit outlet 3 in a single way, or it can switch the mode to connect the vacuum leakage valve 9 and the glue supply gas circuit outlet 3 in a single way. The vacuum leakage valve 9 and the glue supply gas circuit outlet 3 are arranged in the chassis 1.

[0032] The glue supply air path outlet 3 is connected to the rubber hose to provide air pressure for the rubber hose.

[0033] The positive pressure regulating valve 4 and the vacuum leakage valve 9 are both connected to the air pressure sensor 10, which can detect the size of the positive pressure value in the pipeline of the positive pressure regulating valve 4 and the size of the negative pressure value in the pipeline connected to the vacuum leakage valve 9.

[0034] The vacuum leakage valve 9 provides negative pressure, and the gas at the glue supply end is sucked back through the electromagnetic valve 12 to prevent the glue from staying at the glue outlet after dispensing is completed, and the glue is sucked back into the hose.

[0035] A touch screen 6, a trigger switch 7 and a power switch 8 are provided on one side of the chassis 1. A data acquisition board 11 is provided inside the chassis 1. The data acquisition board 11 is a control circuit board. The data acquisition board 11 is connected to the air pressure sensor 10 for collecting air pressure data. The data acquisition board 11 is also connected to the upper MES system. The dispensing controller can be controlled, data can be set and data can be recorded through cloud operation. The data acquisition board 11 is electrically connected to the solenoid valve 12 for switching the control mode. The trigger switch 7 is a manual switch that can trigger pressure. The power switch 8 is the switch for dispensing control. The touch screen 6 is used for data display and control parameter setting.

[0036] Working principle: In glue supply mode, after setting the parameters through the panel of the touch screen 6, the machine starts, the negative pressure regulating valve 13 is closed, the positive pressure regulating valve 4 is opened, and the solenoid valve 12 connects the positive pressure regulating valve 4 and the glue supply gas outlet 3 separately. The gas enters the four pressure-stabilizing gas tanks 2 from the air inlet. The pressure-stabilizing gas tanks 2 adjust the air pressure of the eight air channels separately through the eight-way positive pressure regulating valve 4. The air pressure sensor 10 transmits the pressure value of the eight-way positive pressure regulating valve 4 back to the data acquisition board 11 and feeds it back to the panel of the touch screen 6. The regulated eight-way gas passes through the eight-way solenoid valve 12 to the eight-way glue supply equipment for glue supply operation until the glue supply is completed;

[0037] In the glue return mode, after setting the parameters through the panel of the touch screen 6, when the glue supply operation is completed, the positive pressure regulating valve 4 is closed, the negative pressure regulating valve 13 is opened, and the solenoid valve 12 is connected to the vacuum leakage valve 9 and the glue supply gas outlet 3 separately. The gas passes through the eight-way negative pressure regulating valve 13 from the air inlet, and the air pressure of the eight-way air channel is adjusted separately. The air pressure sensor 10 transmits the pressure value of the eight-way negative pressure regulating valve 13 to the data acquisition board 11 and feeds it back to the panel of the touch screen 6. The regulated eight-way gas passes through the vacuum leakage valve 9 to generate negative pressure, which produces a back-suction effect on the glue supply equipment to prevent glue leakage;

[0038] Through the pressure-stabilizing gas storage tank 2, the solenoid valve 12, the air pressure sensor 10, the data acquisition board 11, the touch screen 6, the adjustment knob, etc., one channel of air intake is distributed into multiple channels to accurately control the output.
