Description

Technical Field

[0001] The present application relates to the technical field of welding pad cleaning devices, and in particular to an alcohol spraying device for welding pads. Background Art

[0002] Currently, in the welding process of flexible wearable devices, alcohol spraying is often used to clean the plate after welding. Existing alcohol spray cleaning methods mostly use needle spraying. Because needle spraying uses a pressing syringe, the amount of alcohol is difficult to control. The needle spray is not precise and can easily spray off the target. Excessive amounts can lead to alcohol penetration or the amount of effect can lead to dirty wipes. In addition, the needle is prone to dust and clogging, requiring frequent needle replacement. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, the present application provides an alcohol spraying device for a solder pad.

[0004] The present application provides an alcohol spraying device for solder pads using the following technical solution:

[0006] By adopting the above technical solution, the nozzle mechanism provides alcohol through an alcohol supply mechanism. After passing through the connecting pipe, the nozzle installed at the output end of the manipulator sprays the alcohol on the welding plate to clean it. The manipulator can drive the nozzle to move. After welding is completed, the nozzle is moved above the welding plate to clean it without interfering with the welding structure. The alcohol container in the alcohol supply mechanism supplies alcohol to the alcohol spray chamber through the supply pipe. The alcohol in the alcohol spray chamber is monitored by a liquid level gauge on its side wall. When it reaches a set value, the alcohol in the alcohol spray chamber is pressed out of the connecting pipe through the pressure mechanism and sprayed onto the welding plate through the nozzle.

[0007] Preferably, the nozzle is mounted on the output end of the universal connector at the output end of the manipulator, and the universal connector is arranged below the output end of the manipulator.

[0008] Preferably, an atomizing nozzle is detachably mounted on the nozzle.

[0009] By adopting the above technical solution, the universal connector installed at the output end of the robot can drive the nozzle to spray alcohol onto the surface of the welding pad at different angles, and a detachable atomizing nozzle is installed on the nozzle. Under normal circumstances, the atomizing nozzle can be used to efficiently spray alcohol on the welding pad, thereby improving the spraying efficiency. If there are stubborn stains on the surface of the welding pad, the atomizing nozzle can be removed and the universal connector can be adjusted to clean the apex of the stubborn stains, thereby meeting the cleaning needs of the welding pad in different situations.

[0013] By adopting the above technical solution, after the alcohol to be sprayed is introduced into the alcohol spray chamber, the supply valve is closed and the spray valve is opened, and the alcohol in the alcohol spray chamber is sprayed through the nozzle through the pressurized cylinder. The conical cavity at the bottom of the cylindrical structure of the alcohol spray chamber can better converge the alcohol to the connecting pipe after pressurization, so that the nozzle can better spray the alcohol.

[0014] Preferably, the supply pipe is connected to a metering pump located at the bottom of the alcohol container, and the metering pump is connected to a controller outside the alcohol container.

[0015] Preferably, the controller is connected to the supply valve, the spray valve, the pressure mechanism and the liquid level meter signal.

[0016] By adopting the above technical solution, the controller controls the metering pump to supply a fixed amount of alcohol to the alcohol spray chamber. At this time, the supply valve is opened and the spray valve is closed. When the liquid level meter detects that the amount of alcohol in the alcohol spray chamber reaches the set value, the metering pump stops working, the supply valve is closed, and the spray valve is opened. Under the action of the pressure mechanism, the alcohol in the alcohol spray chamber is sprayed through the nozzle through the connecting pipe.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0022] The following is combined with Figure 1 This application is described in further detail.

[0023] An embodiment of the present application discloses an alcohol spraying device for a solder pad.

[0024] Reference Figure 1 , an alcohol spraying device for a solder pad, comprising a nozzle mechanism 1, comprising a nozzle 11 and a connecting pipe 12, wherein the nozzle 11 is connected to an alcohol supply mechanism 2 through the connecting pipe 12, and a spray valve 13 is provided on the connecting pipe 12, and the nozzle 11 is installed at the output end of a manipulator 14; the alcohol supply mechanism 2, comprising an alcohol container 21 and an alcohol spray chamber 22, wherein the alcohol container 21 supplies alcohol to the alcohol spray chamber 22 in a quantitative manner through a supply pipe 24, and a supply valve 241 is installed on the supply pipe 24, and a pressure mechanism 23 is provided on the alcohol spray chamber 22 to spray alcohol through the nozzle 11, wherein a liquid level gauge 221 is provided on the side wall of the alcohol spray chamber 22, and the amount of alcohol supplied from the alcohol container 21 to the alcohol spray chamber 22 is adjustable. The nozzle mechanism 1 supplies alcohol through the alcohol supply mechanism 2. After passing through the connecting pipe 12, the nozzle 11 installed at the output end of the manipulator 14 sprays the alcohol on the welding pad for cleaning. The manipulator 14 can drive the nozzle 11 to move. After welding is completed, the nozzle 11 is moved above the welding pad for cleaning without interfering with the welding structure. The alcohol container 21 in the alcohol supply mechanism 2 supplies alcohol to the alcohol spray chamber 22 in a quantitative manner through the supply pipe 24. The alcohol in the alcohol spray chamber 22 is monitored by the liquid level gauge 221 on its side wall. When it reaches the set value, the alcohol in the alcohol spray chamber 22 is pressed out of the connecting pipe 12 through the pressure mechanism 23 and sprayed onto the welding pad through the nozzle.

[0025] Reference Figure 1, the nozzle 11 is installed at the output end of the universal connector 141 at the output end of the manipulator 14, and the universal connector 141 is arranged below the output end of the manipulator 14. An atomizing nozzle 111 is detachably mounted on the nozzle 11. The universal connector 141 mounted at the output end of the manipulator 14 can drive the nozzle 11 to spray alcohol onto the surface of the welding pad at different angles, and a detachable atomizing nozzle 111 is mounted on the nozzle 11. Under normal circumstances, the atomizing nozzle 111 can be used to efficiently spray alcohol on the welding pad, thereby improving the spraying efficiency. If there are stubborn stains on the surface of the welding pad, the atomizing nozzle 111 can be removed and the universal connector 141 can be adjusted to clean the apex of the stubborn stains, thereby meeting the cleaning requirements of the welding pad under different circumstances.

[0026] Reference Figure 1 The alcohol spray chamber 22 adopts a cylindrical structure, wherein the pressure mechanism 23 at the top of the alcohol spray chamber 22 adopts a pressurized cylinder, and the output end of the pressurized cylinder is connected to the top of the alcohol spray chamber 22. A conical cavity 222 is provided at the bottom of the alcohol spray chamber 22, and the bottom of the conical cavity 222 is connected to the connecting pipe 12.

The conical cavity 222 at the bottom of the cylindrical structure of the alcohol spray chamber 22 can better converge the alcohol to the connecting pipe 12 after pressurization, so that the nozzle 11 can better spray the alcohol.

The controller 212 controls the metering pump 211 to supply a fixed amount of alcohol to the alcohol spray chamber 22. At this time, the supply valve 241 is opened and the spray valve 13 is closed. When the liquid level meter 221 detects that the amount of alcohol in the alcohol spray chamber 22 reaches the set value, the metering pump 211 stops working, the supply valve 241 is closed, and the spray valve 13 is opened. Under the action of the pressure mechanism 23, the alcohol in the alcohol spray chamber 22 is sprayed through the nozzle 11 through the connecting pipe 12.

[0028] Working principle: Under the control of the controller 212, the supply valve 241 is opened, the spray valve 13 is closed, and the metering pump 211 at the bottom of the alcohol container 21 is started to supply alcohol to the alcohol spray chamber 22 through the supply pipe 24. After the alcohol in the alcohol spray chamber 22 reaches the set value through the liquid level gauge 221 on its side wall, the metering pump 211 stops working, the supply valve 241 is closed, and the spray valve 13 is opened. The alcohol in the alcohol spray chamber 22 is pressed out from the connecting pipe 12 through the pressure mechanism 23 and sprayed onto the welding disk through the nozzle.
