[0025] The following describes the filling device of the diluent for soaking the needle of the coating device according to the embodiment of the present invention in conjunction with the accompanying drawings.

[0026] like Figure 1-4 As shown, the diluent filling device for soaking needles in the coating equipment according to the embodiment of the present invention includes a weight detection mechanism 10, a pressure barrel 20, a diluent container 30, a control mechanism 40, a diluent storage cup 50 and a liquid level sensor 60.

[0027] Among them, the pressure barrel 20 is set on the top wall of the weight detection mechanism 10, the diluent holding barrel 30 is movably set in the pressure barrel 20, the control mechanism 40 is set on the pressure barrel 20, the diluent storage cup 50 is connected to the pressure barrel 20 through a pipeline, and the liquid level sensor 60 is set on the diluent storage cup 50.

[0028] It should be noted that the pressure barrel 20 is removably mounted on the weight detection mechanism 10. A cover plate is provided on top of the pressure barrel 20, and the control mechanism 40 is mounted on the cover plate to maintain a good seal on the pressure barrel 20. The diluent container 30 is placed within the pressure barrel 20, and the control mechanism 40 controls the addition of diluent from the diluent container to the diluent storage cup 50.

[0029] Specifically, the diluent for soaking the needle is added in real time through the coating equipment, the whole barrel of diluent containing barrel 30 is placed in the pressure barrel 20, and the diluent is added to the diluent storage cup 50 through the control component to soak the needle.

[0030] In one embodiment of the present invention, Figure 1 As shown, the control mechanism 40 includes a pressure relief valve 401 , a regulating valve 402 , a pressure regulating valve 403 and a control valve 404 .

[0031] The pressure relief valve 401 is provided on the pressure barrel 20 , the regulating valve 402 is provided on the pressure barrel 20 , the pressure regulating valve 403 is provided on the pressure barrel 20 , and the control valve 404 is provided on the pipe connecting the diluent storage cup 50 and the pressure barrel 20 .

[0032] It should be noted that in this embodiment, air pressure is used as the diluent output power, and is equipped with corresponding pressure relief valve 401, outlet pressure regulating valve 403, air supply pressure regulating valve 402 and control valve 404 to ensure the stability of the diluent supply pressure.

[0033] In one embodiment of the present invention, Figure 3 As shown, the weight detection mechanism 10 includes a chassis 101 and a gravity sensor 102 .

[0034] There are multiple groups of gravity sensors 102 , which are respectively arranged on the chassis 101 , and the pressure barrel 20 is arranged on the gravity sensors 102 .

[0035] It should be noted that the gravity sensor 102 will send an alarm signal to the coating equipment when the remaining weight of the diluent in the diluent spare barrel assembly is lower than the set value. The equipment will stop running and prompt the personnel to replace the full barrel of diluent. This can effectively solve the quality problems and equipment shutdowns caused by personnel forgetting to add diluent.

[0036] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, the filling device of the needle diluent for soaking the coating equipment of the present invention also includes a control component, and the control component includes a control box and a controller.

[0037] The controller is disposed inside the control box, and is electrically connected to the liquid level sensor 60 and the control valve 404 , respectively.

[0038] It should be noted that the control box and the controller in the control assembly are conventional technologies. The controller is electrically connected to the liquid level sensor 60 and the control valve 404 respectively, and adds diluent to the diluent storage cup 50 in real time.

[0039] The steps of adding diluent in real time during the soaking of the needle in the coating device of the utility model are:

[0040] 1. The diluent container 30 is placed entirely within the pressure barrel 20, using air pressure as the diluent output power. It is equipped with a corresponding pressure relief valve 401, outlet pressure regulating valve 403, air supply pressure regulating valve 402, and control valve 404 to ensure a stable diluent supply pressure. Furthermore, diluent can be added entirely from the original packaging barrel, eliminating the need for secondary packaging or manual addition, and preventing spills that could affect the environment or the health of operators.

[0041] 2. A gravity sensor 102 is installed at the bottom of the diluent container 30. When the remaining weight of the diluent in the diluent container 30 is lower than the set value, an alarm signal will be sent to the coating equipment, the equipment will stop running, and the personnel will be prompted to replace the full barrel of diluent. This can effectively solve the quality problems and equipment downtime caused by personnel forgetting to add diluent.

[0042] 3. Independent high and low level liquid level sensors 60 are installed on the needle soaking diluent storage cup 50 inside the coating equipment. The liquid level sensor 60 can automatically detect the liquid level of the needle soaking diluent in the equipment and transmit the signal to the diluent automatic filling control component. When the low level sensor is not triggered, the diluent automatic filling control component controls the opening of the diluent filling control valve 404 to inject the diluent from the diluent storage barrel 30 into the needle soaking diluent storage cup 50 inside the coating equipment; when the high level sensor is triggered, the diluent automatic filling control component controls the closing of the diluent filling control valve 404; this can not only realize the automatic addition of diluent to the needle soaking diluent storage cup 50 inside the coating equipment, but also effectively avoid product quality problems caused by excessive diluent volatilization without replenishment and needle solidification; at the same time, it can effectively avoid the impact of overflow and leakage on the environment and the health of the operator due to excessive addition or manual addition.

[0043] In summary, the filling device for diluent soaking the needle of the coating equipment in the embodiment of the utility model effectively reduces equipment downtime and improves production efficiency. At the same time, it avoids defective products caused by needle blockage due to personnel forgetting to manually add diluent, and completely avoids the impact on the environment and the health of the operator due to excessive manual addition or overflow and leakage during manual addition.
