Description

Technical Field

[0001] This application relates to the field of infrared detector dewar technology, and more particularly to a rapid curing adhesive applicator. Background Technology

[0002] Infrared detectors, as core optoelectronic sensing components, have been widely used in meteorological monitoring, non-destructive testing, aerospace remote sensing, and military reconnaissance and tracking. The Dewar flask, a key component of the infrared detector, functions to provide and maintain a necessary ultra-high vacuum and cryogenic operating environment for the detector chip. The vacuum maintenance capability of the Dewar flask, i.e., its effective lifespan, directly determines the overall service life of the infrared detector. Therefore, improving the Dewar flask's adaptability to harsh environments is a crucial technical factor in ensuring the stable and reliable operation of the entire detector system.

[0003] Currently, the mainstream process for maintaining the vacuum life of Dewar flasks in the industry involves creating a vacuum through high-temperature exhaust, then cold-press-welding the exhaust pipe to seal it, followed by applying and curing vacuum sealant to achieve a secondary seal. While this process effectively guarantees the final vacuum level, it has a significant drawback: the sealant takes an extremely long time to cure during the secondary sealing process. This severely restricts the production efficiency of Dewar flasks, increases manufacturing costs, and the prolonged curing process can easily lead to sealant leakage, increasing the instability of the secondary seal.

[0004] Therefore, there is an urgent need to develop an efficient and rapid adhesive coating and curing method that can significantly shorten the secondary sealing process cycle without sacrificing the ultra-high vacuum performance and long-term reliability of the Dewar flask, so as to break through the efficiency bottleneck of the existing production mode. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a rapid curing adhesive applicator to solve the technical problem that existing adhesive applicator processes cannot quickly achieve sealant curing.

[0006] To achieve the above technical objectives, this application provides a rapid curing adhesive applicator, including a hydraulic tank and an adhesive storage tank;

[0007] The hydraulic tank includes a tank body, multiple guide tubes, and a dispensing tube; the tank body is fitted with a mixing chamber, a heating device, and a first weighing device in sequence from top to bottom; one end of each of the multiple guide tubes is connected to a corresponding multiple storage tanks, and the other end is connected to the tank body for conveying adhesive to the mixing chamber, and each guide tube is equipped with a valve for controlling the flow of adhesive; one end of the dispensing tube extends into the mixing chamber, and the other end extends to the outside of the tank body.

[0008] Furthermore, the glue applicator is fixed to one end of the glue outlet tube extending to the outside of the tank. The glue applicator is used to apply glue to the Dewar bottle. The second weighing device is located below the glue applicator to support the Dewar bottle and monitor the mass change of the Dewar bottle during the glue application process.

[0009] Furthermore, the top of the second weighing device is provided with a groove for fitting into the bottom of the Dewar flask to secure it.

[0010] Furthermore, a fixing member is provided on the top of the second weighing device, and the fixing member is detachably connected to the second weighing device; the fixing member is used to fix the Dewar flask on the top of the second weighing device.

[0011] Furthermore, the top of the second weighing device is provided with a groove; the fixing member is a cylindrical body adapted to the body of the Dewar flask, and the bottom of the cylindrical body is provided with a protrusion, which fits into the groove to fix the fixing member to the top of the second weighing device.

[0012] Furthermore, the fastener is a holder with a groove on one side, which is used to fit the bottom of the Dewar flask to fix the Dewar flask; the other side opposite the groove can be detachably fixed to the top of the second weighing device.

[0013] Furthermore, a rotating platform is provided between the fixing component and the second weighing device; the rotating platform includes a base plate disposed at the top of the second weighing device, a support shaft vertically disposed on the base plate, and a turntable sleeved on the support shaft and rotating around the axis of the support shaft; the turntable is connected to the fixing component in a transmission manner.

[0016] Furthermore, the dispensing tube extends vertically through the top of the tank along its own axis, and the dispensing tube is an axially retractable structure.

[0017] In summary, this application provides a rapid curing adhesive application device, including a hydraulic tank and an adhesive storage tank. The hydraulic tank includes a tank body, multiple adhesive guide tubes, and an adhesive outlet tube. Inside the tank body, from top to bottom, are sequentially fitted a stirring chamber, a heating device, and a first weighing device.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] This application provides a rapid curing adhesive application device, including a hydraulic tank and an adhesive storage tank. The hydraulic tank includes a tank body, multiple adhesive guide tubes, and an adhesive outlet tube, wherein the adhesive guide tubes and the adhesive outlet tube both penetrate the tank body to form a communication channel between the inside and outside of the tank body. Inside the tank body, from top to bottom, a stirring chamber, a heating device, and a first weighing device are sequentially attached to each other to realize the receiving, stirring, heating, and quality monitoring of the adhesive solution. Specifically, the multiple adhesive guide tubes are connected to multiple adhesive storage tanks one-to-one, with one end connected to the outlet end of the adhesive storage tank and the other end connected to the tank body to transport the adhesive solution to the stirring chamber inside the tank body. Each adhesive guide tube is equipped with a valve to control the flow of the adhesive solution. The stirring chamber is used to receive the adhesive solution transported by the multiple adhesive guide tubes and stir it. The stirred adhesive solution is discharged through the adhesive outlet tube, which extends into the stirring chamber at one end and to the outside of the tank body at the other end, under the pressure applied by the hydraulic tank. In addition, the heating device is fitted to the bottom outer wall of the mixing chamber to provide precise heat supply for the adhesive mixing process, so as to ensure the temperature conditions required for the rapid curing of the adhesive; the first weighing device is fitted to the lower end of the heating device to weigh the heating device, the mixing chamber and the adhesive inside the mixing chamber as a whole, thereby monitoring the quality changes in the adhesive mixing process in real time and ensuring the accuracy of the adhesive ratio.

[0026] In some embodiments, the glue applicator is fixed to one end of the glue outlet tube extending to the outside of the tank, and the glue applicator is used to apply glue to the Dewar flask; a second weighing device is disposed below the glue applicator to support the Dewar flask and monitor the mass change of the Dewar flask during the glue application process.

[0027] It should be noted that during the glue application process, the Dewar bottle is placed on the second weighing device, and the glue applicator accurately applies the stirred and cured glue to the target area of ​​the Dewar bottle. Since the hydraulic tank is in a preset hydraulic state during glue application, this hydraulic environment will interfere with the weighing data of the first weighing device, causing its monitoring results to fail to accurately reflect the actual output changes of the glue. Therefore, it is necessary to use the second weighing device to monitor the quality changes of the product in real time during the glue application process, and then accurately calculate the actual glue output to ensure the control accuracy of the glue application amount.

[0028] In some embodiments, the top end of the second weighing device has a groove for fitting the bottom of the fixing member to secure it. In some preferred embodiments, the lower end of the second weighing device has a rotating platform, which is connected to the second weighing device for driving the fixing member fixed on the second weighing device to rotate stably around its own axis, thereby achieving uniform rotational adhesive application.

[0029] It should be noted that the axial outer wall of the Dewar flask is a cylindrical body. Based on this structural feature, the groove at the top of the second weighing device can be used to directly fix the bottom of the Dewar flask by adapting its shape.

[0030] In some embodiments, a fixing member is provided on the top of the second weighing device, and the fixing member is detachably connected to the second weighing device; the fixing member is used to fix the Dewar flask on the top of the second weighing device.

[0031] In some specific embodiments, the top of the second weighing device has a groove; the fixing member is a cylindrical body adapted to the body of the Dewar flask, and the bottom of the cylindrical body has a protrusion that fits into the groove to fix the fixing member to the top of the second weighing device. In some more preferred embodiments, the lower end of the second weighing device has a rotating platform, which is connected to the second weighing device for driving the Dewar flask fixed on the second weighing device to rotate stably around its own axis, thereby achieving uniform rotational coating.

[0032] In some specific embodiments, the fixing component includes a chassis, a support rod fixed to the chassis, and an annular component disposed on the support rod; the annular component is used to fit the Dewar flask and fix its body.

[0033] In some specific embodiments, the fastener is a holder with a groove on one side, which is used to fit the bottom of the Dewar bottle to fix the Dewar bottle; the other side opposite the groove can be detachably fixed to the top of the second weighing device.

[0034] In some embodiments, a rotating platform is provided between the fixing member and the second weighing device; the rotating platform includes a base plate disposed at the top of the second weighing device, a support shaft vertically disposed on the base plate, and a turntable sleeved on the support shaft and rotating about the axis of the support shaft; the turntable is connected to the fixing member in a transmission manner. During the glue application process, the Dewar bottle can be stably rotated by driving the rotating platform to transmit power to the fixing member, which helps to improve the uniformity of glue application.

[0035] In some embodiments, the glue storage tank is disposed at the top of the hydraulic tank and corresponds vertically to the mixing chamber; the bottom of the glue storage tank is connected to one end of the glue guide tube, and the other end of the glue guide tube is vertically downward connected to the tank body along its own axis.

[0036] It should be noted that by placing the glue storage tank in the upper area of ​​the hydraulic tank and connecting them with a glue guide tube to form a vertical channel, the glue can flow directly into the mixing chamber along the guide tube under the influence of gravity. This setup eliminates the need for additional extension or bending of the guide tube, simplifying its layout and effectively reducing material waste, thus achieving lightweight design and cost optimization of the device.

[0037] In some embodiments, the adhesive guide tube is further provided with an adhesive quantity controller, which includes a flow regulation structure and a drive structure. The drive structure is used to drive the adhesive output, and the flow regulation structure is used to regulate the output flow rate of the adhesive. It should be noted that the adhesive quantity controller can be used to control the material conveying from the adhesive storage tank to the hydraulic tank. Through the cooperation of the adhesive quantity controller and the first weighing device, precise control of the adhesive mixing ratio can be achieved.

[0038] In some embodiments, the mixing chamber is provided with a spiral stirrer, a vortex stirrer, or an anchor stirrer.

[0039] In some embodiments, the dispensing tube extends vertically through the top of the tank along its own axis, and the dispensing tube is an axially retractable structure.

[0040] It should be noted that by setting the dispensing tube to a telescopic structure, it can not only adapt to different glue levels inside the mixing chamber, but also flexibly adjust the distance between the applicator and the workpiece.

[0041] The applicant further provides the following specific embodiments to describe the present invention. It should be noted that these embodiments are merely descriptive and do not limit the present invention in any way.

[0042] Example 1

[0043] See Figure 1This embodiment provides a rapid curing adhesive application device, including a hydraulic tank 1 and an adhesive storage tank 2. The hydraulic tank 1 includes a tank body 11, an adhesive guide tube 12 extending axially through the top of the tank body 11, and an adhesive outlet tube 13. Two adhesive storage tanks 2 are provided, one for storing adhesive A and the other for adhesive B. The adhesive storage tank 2 is located at the top of the hydraulic tank 1. The bottom of the adhesive storage tank 2 is connected to one end of the adhesive guide tube 12, and the other end of the adhesive guide tube 12 extends vertically downwards along its own axis to connect to the tank body 11. The adhesive guide tube 12 is equipped with an adhesive quantity controller and a valve. When adhesive needs to be delivered, the valve on the adhesive guide tube 12 is opened, and the flow rate and total amount of adhesive delivered from the adhesive storage tank 2 to the hydraulic tank 1 are controlled by adjusting the adhesive quantity controller.

[0044] The tank body 11 is fitted with a mixing chamber 111, a heating device 112, and a first weighing device 113 from top to bottom. The mixing chamber 111 is used to receive A glue and B glue input by the glue guide tube 12. During glue preparation, the two glue solutions are mixed evenly by the vortex stirrer inside the mixing chamber 111. At the same time, the heating device 112 is used to provide precise heating to the mixing chamber 111 to control the glue solution temperature. The first weighing device 113 is used to weigh the mixing chamber 111, the heating device 112, and the glue solution inside as a whole, so as to achieve accurate measurement and monitoring of the ratio of A glue to B glue.

[0045] The top of the second weighing device 32 has a groove; the fixing member 4 is a cylindrical body adapted to the body of the Dewar flask, and the bottom of the cylinder has a protrusion. The protrusion fits into the groove to fix the fixing member to the top of the second weighing device. During the glue application operation, the Dewar flask to be glued is assembled into the cylinder and fixed. After fixing, the hydraulic tank 1 is started to generate a preset pressure inside. Under the action of pressure, the mixed glue is transported to the glue applicator 31 along the glue outlet pipe 13. The glue applicator 31 applies the glue to the target area of ​​the Dewar flask. During the glue application process, the actual amount of glue applied to the surface of the Dewar flask is accurately obtained by monitoring the mass change of the second weighing device 32 in real time.

[0046] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features.
