[0036] Next, combine Figure 1-Figure 4 , an exemplary description of the present application is given.

[0037] An embodiment of the present application provides a silicone foaming and coating device, such as Figure 1 and Figure 2 As shown, the glue coating equipment includes:

[0038] A first glue liquid feeding mechanism 1, which includes a first glue liquid storage tank 1.1, a first delivery pipeline 1.2, a first metering pump 1.3 and a first constant temperature system 1.4, wherein the first glue liquid (component A glue liquid) is stored in the first glue liquid storage tank 1, the first delivery pipeline 1.2 is connected to the inside of the first glue liquid storage tank 1, and is used to deliver the first glue liquid, the first metering pump 1.3 is arranged on the first delivery pipeline 1.2, and is used to meter the flow rate of the first glue liquid, and the first constant temperature system 1.4 is arranged on the first delivery pipeline 1.2, and is used to keep the glue liquid in the first delivery pipeline 1.2 at a constant temperature, in a constant temperature state;

[0039] A second glue liquid feeding mechanism 2, which includes a second glue liquid storage tank 2.2, a second delivery pipeline 2.2, a second metering pump 2.3 and a second constant temperature system 2.4, wherein the second glue liquid storage tank 2 stores the second glue liquid (B component glue liquid), the second delivery pipeline 2.2 is connected to the inside of the second glue liquid storage tank 2, and is used to deliver the second glue liquid, the second metering pump 2.3 is arranged on the second delivery pipeline 2.2, and is used to meter the flow rate of the second glue liquid, and the second constant temperature system 2.4 is arranged on the second delivery pipeline, and is used to keep the glue liquid in the second delivery pipeline 2.2 at a constant temperature, in a constant temperature state;

[0040] The glue dispensing mechanism 3 includes a glue liquid chamber 3.1, a stirring unit 3.2 and a glue dispensing head 3.3, wherein the first glue liquid storage tank 1.1 is connected to the glue liquid chamber 3.1 through a first conveying pipeline 1.2, and the second glue liquid storage tank 2.1 is connected to the glue liquid chamber 3.1 through a second conveying pipeline 2.2. The stirring unit 3.2 is arranged in the glue liquid chamber 3.1, and is used to stir and mix the first glue liquid and the second glue liquid introduced into the glue liquid chamber to form a mixed glue liquid. The glue dispensing head 3.3 is connected to the glue liquid chamber 3.1, and is used to discharge the mixed glue liquid in the glue liquid chamber.

[0041] When in use, the first metering pump 1.3 and the second metering pump 2.3 are used to control the first glue liquid and the second glue liquid in the first glue liquid storage tank 1.1 and the second glue liquid storage tank 2.2 to enter the glue liquid chamber 3.1 in a ratio of 1:1, and then the first glue liquid and the second glue liquid are uniformly stirred and mixed in the same proportion by the stirring unit 3.2 to form a mixed glue liquid, and finally the mixed glue liquid is discharged by the dispensing head 3.3. The dispensing head 3.3 is installed on a three-axis moving module. The three-axis moving module can drive the dispensing head to move up and down, left and right, front and back, so as to accurately apply the glue liquid to the designated parts of the doors and windows of the laboratory clean room.

[0042] In some embodiments, Figure 3 As shown, the first glue storage tank 1.1 and the second glue storage tank 2.1 respectively include a tank body 100 and a first stirring device 200. A feed port 300 is provided on the top of the tank body 100, and glue is added into the tank body through the feed port 300. The first stirring device 200 includes a first motor 201, a first rotating shaft 202 and a first stirring blade 203. The top of the first rotating shaft 202 extends out of the tank body 100 and is connected to the output end of the first motor 201. The bottom of the first rotating shaft 202 extends into the tank body 100 and the first stirring blade 203 is fixedly arranged at the bottom of the first rotating shaft 202 and rotates synchronously with the first rotating shaft 202. Since the component glue contains a curing agent, a stirring device is arranged in the storage tank. The motor drives the rotating shaft to drive the paddle to rotate, and the paddle keeps the glue in the storage tank in a circulating state, thereby preventing the glue in the tank from solidifying due to standing.

[0043] In some embodiments, Figure 3 As shown, a ring-shaped heating wire 400 is arranged in the tank body 100. The heating wire 400 can heat the glue in the tank to keep the glue at a certain temperature, thereby effectively preventing the glue from solidifying due to low temperature.

[0044] In some embodiments, Figure 3 As shown, the tank body 100 includes an inner tank body 101 and an outer tank body 102. The inner tank body 101 is used to store glue. An insulation layer 103 is arranged in the interlayer between the inner tank body 101 and the outer tank body 102. Insulation liquid is passed into the insulation layer 103. The insulation layer filled with insulation liquid can isolate the glue inside the inner tank body from the external environment, thereby playing an effective insulation role and preventing the glue from solidifying due to low temperature. An insulation liquid inlet is opened on the outer tank body 102, and the insulation liquid is passed into the insulation layer 103 through the insulation liquid inlet.

[0045] In some embodiments, Figure 4 As shown, the glue dispensing mechanism 3 also includes a first glue dispensing valve 3.4 and a second glue dispensing valve 3.5, wherein the first glue dispensing valve 3.4 is arranged at the position where the first conveying pipeline 1.2 and the glue liquid chamber 3.1 are connected, and the second glue dispensing valve 3.5 is arranged at the position where the second conveying pipeline 2.2 and the glue liquid chamber 3.1 are connected. The first glue dispensing valve 3.4 is used to control the first glue liquid in the first conveying pipeline 1.2 to pass into the glue liquid chamber 3.1, and the second glue dispensing valve 3.5 is used to control the second glue liquid in the second conveying pipeline 2.2 to pass into the glue liquid chamber 3.1. When the device is in use, the first glue dispensing valve 3.4 and the second glue dispensing valve 3.5 are opened synchronously, so as to ensure that the first glue liquid and the second glue liquid enter the glue liquid chamber 3.1 in the same proportion for mixing, and when the device is not in use, the first glue dispensing valve 3.4 and the second glue dispensing valve 3.5 are closed synchronously.

[0046] In some embodiments, Figure 4 As shown, the first delivery pipeline 1.2 and the second delivery pipeline 2.2 respectively include a liquid inlet pipeline A and a liquid return pipeline B. The first end of the liquid inlet pipeline A is connected to the tank body, and the second end of the liquid inlet pipeline A is connected to the glue liquid cavity 3.1. The first end of the liquid return pipeline B is connected to the glue liquid cavity 3.1, and the second end of the liquid return pipeline B is connected to the tank body. Since the glue liquid contains a curing agent, the glue liquid will solidify when it is in a static state. In order to avoid this situation, when the dispensing valve is closed, the glue liquid can flow back to the storage tank through the liquid return pipeline B, thereby ensuring that the glue liquid is in a state of continuous circulation, effectively avoiding the glue liquid from solidifying due to standing.

[0047] In some embodiments, the stirring unit 3.2 includes a second motor 3.2.1, a second rotating shaft 3.2.2 and a second stirring blade 3.2.3, wherein the top of the second rotating shaft 3.2.2 extends out of the glue chamber 3.1 and is connected to the output end of the second motor 3.2.1, the bottom of the second rotating shaft 3.2.1 extends into the glue chamber 3.1 and the second stirring blade 3.2.3 is fixedly arranged at the bottom of the second rotating shaft 3.2.1 and rotates synchronously with the second rotating shaft 3.2.2. When rotating, the two stirring blades 3.2.3 can stir the first glue and the second glue in the glue chamber 3.1 to evenly mix them to form a mixed liquid.

[0048] In some embodiments, the device also includes a cleaning unit 4, which is used to clean the glue in the glue chamber 3.1. The cleaning unit 4 includes a cleaning liquid delivery pipeline 4.1 and a cleaning pump 4.2. The first end of the cleaning liquid delivery pipeline 4.1 is connected to the cleaning liquid delivery source (cleaning liquid storage tank 4.3), and the second end of the cleaning liquid delivery pipeline 4.1 is connected to the glue chamber 3.1. A cleaning liquid valve 4.4 is provided at the connection between the second end of the cleaning liquid delivery pipeline 4.1 and the glue chamber 3.1. Since the mixed glue contains a curing agent, after the equipment is stopped, the mixed glue remaining in the glue chamber 3.1 will block the glue chamber 3.1 after curing, resulting in subsequent inability to use normally. Therefore, it is necessary to clean the mixed glue remaining in the glue chamber 3.1. The cleaning is achieved by passing the cleaning liquid into the glue chamber 3.1, and the cleaning liquid is controlled by the cleaning liquid valve 4.4.
