[0063] In order to make those skilled in the art better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0064] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0065] See also Figures 1 to 5 The embodiment of the present invention provides a glue ultrasonic vacuum centrifugal degassing device, comprising: an inner barrel 10, an outer barrel 20, a rotating assembly 30 and an ultrasonic vibration assembly 40, wherein the inner barrel 10 is used to be connected to a vacuum pumping device so that the air in the inner barrel 10 is extracted under the action of the vacuum pumping device to form a vacuum state; the outer barrel 20 is arranged on the outer side of the inner barrel 10, and a vacuum joint 205 is provided on the outer barrel 20, and the vacuum joint 205 is used to be connected to the vacuum equipment; the rotating assembly 30 includes a motor 301, and the motor 301 is connected to the inner barrel 10 to drive the inner barrel 10 to rotate; the ultrasonic vibration assembly 40 includes an ultrasonic device 401, and the ultrasonic device 401 is used to drive the inner barrel 10 to perform ultrasonic vibration through the rotating assembly 30.

[0066] like Figures 1 to 5 As shown in the figure, in order to degas the glue, when in use, the glue can be injected into the inner barrel 10 through the liquid inlet joint 206, and after the inner barrel 10 is sealed, the air in the inner barrel 10 is extracted through the vacuum device, so that the inner barrel 10 forms a vacuum environment, so that the glue in the inner barrel 10 can be better degassed. At the same time, the motor 301 in the rotating assembly 30 can drive the inner barrel 10 to rotate. While the inner barrel 10 is rotating, the ultrasonic device 401 drives the inner barrel 10 to vibrate ultrasonically. In this process, the glue in the inner barrel 10 can be driven to rotate centrifugally and vibrate ultrasonically, and then the bubbles in the glue are broken, and the degassing operation of the glue is realized, so that the bubbles in the glue can be reduced or even eliminated, and the accuracy of the glue dispensing during dispensing is improved. In the embodiment of the present invention, vacuum centrifugal rotation and ultrasonic vibration are used together. The bubbles in the glue can be eliminated more cleanly.

[0067] See also Figures 2 to 5 The rotating assembly 30 further includes a motor connector 302, and the motor 301 is connected to the outer barrel 20 via the motor connector 302. Figure 3 As shown in , the lower end of the inner barrel 10 is connected to the motor 301 of the rotating assembly 30 through the glue outlet. In this way, when the motor 301 rotates, the inner barrel 10 can be driven to rotate. The motor connector 302 is arranged between the inner barrel 10 and the outer barrel 20. The outer barrel 20 and the motor 301 can be fixedly connected, so that the inner barrel 10 can be rotatably arranged inside the outer barrel 20, and the inner barrel 10 can be protected to a certain extent by the outer barrel 20.

[0068] See also Figures 3 to 5 The ultrasonic vibration component 40 also includes: a base 402, a floating connector 403 and a floating connection plate 404. The floating connector 403 is provided with one or more, and each floating connector 403 is fixedly connected to the base 402; the motor 301 and the ultrasonic device 401 are respectively installed and fixed on the floating connection plate 404, and are connected to the floating joint through the floating connection plate 404.

[0069] like Figures 3 to 5 As shown in , the glue ultrasonic vacuum centrifugal degassing device can be installed and fixed through the base 402. The ultrasonic devices 401 are respectively installed and fixed on the floating connecting plate 404. In this way, the ultrasonic device 401 can drive the floating connecting plate 404 to vibrate synchronously. Since the floating connecting plate 404 is connected to the inner barrel 10 through the motor 301. In this way, while the floating connecting plate 404 vibrates under the action of the ultrasonic device 401, it can drive the motor 301 and the inner barrel 10 to vibrate. Thereby, the vibration degassing of the glue in the inner barrel 10 is controlled. Since the floating connecting plate 404 is floatingly connected to the bottom plate through one or more floating connectors 403, the floating connecting plate 404 can vibrate relative to the base 402 under the action of the ultrasonic device 401.

[0070] See also Figure 4 and Figure 5 The glue ultrasonic vacuum centrifugal degassing device further comprises a sealing and rotating connecting member 50, through which the inner barrel 10 is sealed and rotatably connected to the outer barrel 20. Figure 4 and Figure 5As shown in FIG. 1 , the inner barrel 10 rotates at a high speed under the control of the motor 301, so that the glue in the inner barrel 10 is centrifugally rotated to degas. The inner barrel 10 and the outer barrel 20 can be sealed and rotatably connected through the sealing and rotating connecting member 50. The friction resistance between the inner barrel 10 and the outer barrel 20 is reduced, thereby reducing the heat problem caused by friction.

[0071] See also Figure 4 and Figure 5 The glue ultrasonic vacuum centrifugal degassing device further includes: a vacuum pressure sensor 60 and a vacuum breaking connector 202. The vacuum pressure sensor 60 is installed on the cover of the outer barrel 20 and is interconnected with the inner barrel 10 to detect the vacuum pressure of the inner barrel 10; the vacuum breaking connector 202 is installed on the cover of the outer barrel 20 and is interconnected with the inner barrel 10. Figure 4 and Figure 5 As shown in , the vacuum pressure sensor 60 can detect the vacuum negative pressure of the inner barrel 10. In this way, the vacuum pumping device can control the vacuum pumping of the inner barrel 10 according to the detected vacuum negative pressure detection value to ensure the purity of the degassing of the glue. After the degassing is completed, the vacuum breaking connector 202 can be connected to the external environment to break the vacuum of the inner barrel 10. In this way, it is convenient to discharge the degassing glue to the outside for use.

[0072] See also Figure 4 and Figure 5 The glue ultrasonic vacuum centrifugal degassing device comprises: a glue outlet assembly 70, wherein the glue outlet assembly 70 comprises a glue outlet connecting pipe 701, wherein the glue outlet connecting pipe 701 is connected to the inner barrel 10 to lead the glue in the inner barrel 10 outward. Figure 4 and Figure 5 As shown in the figure, a manual control switch 706 may be provided on the glue outlet connecting pipe 701. When the glue is degassed and needs to be discharged to the outside for use, the manual control switch 706 can be manually controlled to open the glue output channel, and the glue in the inner barrel 10 can be discharged to the outside through the glue outlet connecting pipe 701.

[0073] See also Figure 4 and Figure 5The glue discharging assembly 70 further includes: a temperature detector 702, which is installed on the glue discharging connection pipe 701, and is used to detect the temperature of the glue in the inner barrel 10. The outer barrel 20 is also provided with a cooling connector 201, which is connected to the outer side of the inner barrel 10, and is used to connect with a cooling device to control the temperature of the inner barrel 10 according to the temperature detection value of the temperature detector 702. Since the rotation of the inner barrel 10 will drive the glue in the inner barrel 10 to do centrifugal movement, in this process, the glue and the inner barrel 10 will generate a large amount of heat, thereby causing the inner barrel 10 to heat up. When the temperature is high, it is necessary to cool the inner barrel 10 and the glue in the inner barrel 10. The temperature of the glue in the inner barrel 10 can be detected by the temperature detector 702, and when a high temperature is detected, cooling gas can be output through the cooling device and output to the outer surface of the inner barrel 10 through the cooling connector 201, thereby cooling the inner barrel 10. When the temperature is cooled to a state close to normal temperature, the cooling can be stopped. In this way, it is ensured that the glue in the inner barrel 10 does not rise to an excessively high temperature value.

[0074] See also Figure 4 and Figure 5 The glue discharging assembly 70 further includes: a lower liquid level detector 703, which is installed on the glue discharging connecting pipe 701 and is used to detect the lower liquid level of the glue in the inner barrel 10; an upper liquid detector 203 is also provided above the outer barrel 20, and the upper liquid detector 203 is used to detect the upper liquid level of the glue in the inner barrel 10. The glue in the inner barrel 10 and the glue discharging connecting pipe 701 can be detected by the lower liquid level detector 703 and the lower liquid detector. Whether it is necessary to inject glue into the inner barrel 10 or whether it is necessary to continue to discharge glue to the outside can be controlled according to the amount of glue.

[0075] See also Figure 4 and Figure 5 The glue discharging assembly 70 further includes a liquid pump 704, which is connected to the glue discharging connecting pipe 701 to control the glue discharging of the inner barrel 10. The liquid pump 704 can control the glue to be discharged when it is necessary to discharge the glue to the outside.

[0076] See also Figure 4 and Figure 5The glue discharging assembly 70 also includes: a glue discharging connector 705, which is connected to the output end of the liquid pump 704; the outer barrel 20 is also provided with a reflux connector 204, which is also connected to the glue discharging connector 705 through a connecting pipe. The glue can be connected to the glue dispensing barrel through the glue dispensing connector 705 to discharge the glue to the outside and inject it into the glue dispensing barrel for glue dispensing. In addition, when the glue degassing condition cannot meet the requirements, the glue can also be refluxed to the inner barrel 10 through the reflux connector 204 for further degassing operation to meet the high-precision glue dispensing requirements.
