[0009] Furthermore, the stirring paddle adopts a cylindrical structure with multiple square holes on its outer circumferential wall, which is compatible with the heating barrel.

[0010] Furthermore, the heating bucket adopts an integral structure formed by the bucket body and the electric heating layer provided on the outer wall of the bucket body.

[0015] Advantages of this invention compared to existing technologies:

[0016] 1. This technical solution involves setting a vibrating base on a support and a heated glue tank fixed on a vibrating platform on the vibrating base.

Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In this document, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0028] A small adhesive degassing device includes a support frame 1, with a vibrating base 2 at the upper end of the support frame 1. A heated adhesive tank 3 is detachably clamped and fixed to the vibrating platform of the vibrating base 2, and the adhesive inside the heated adhesive tank 3 is vibrated under the vibration of the vibrating base 2. A lifting stirring device is provided on the vibrating platform of the vibrating base 2 and is rotatably sealed to the middle of a detachable tank lid 4 at the upper end of the heated adhesive tank 3. The stirring part of the lifting stirring device extends into the heated adhesive tank 3 and stirs the adhesive inside. The connector at the upper end of the heated adhesive tank 3 is connected to a vacuum system, and the vacuum system extracts the gas discharged from the adhesive inside the heated adhesive tank 3 or the gas filled into the heated adhesive tank 3 crushes and eliminates bubbles on the adhesive surface. The heated adhesive tank 3 is provided with a liquid level detection element for detecting the liquid level inside; the liquid level detection element is a liquid level sensor 17.

[0029] The specific structure of the vacuum system is as follows: The vacuum system includes a Y-type vacuum tube 5, a vacuum valve 6, and a vacuum valve 7. The main pipeline of the Y-type vacuum tube 5 is connected to the air inlet of the vacuum pump 8 located inside the bracket 1, and a vacuum valve 7 is installed on the main pipeline of the Y-type vacuum tube 5. A vacuum gauge 9 is installed on one of the branches of the Y-type vacuum tube 5 that is connected to the connector at the upper end of the heating glue tank 3, so as to facilitate the vacuum measurement of the heating glue tank 3. The vacuum valve 6 is installed on the other branch of the Y-type vacuum tube 5, and the switching between the vacuum state and the gas filling state in the heating glue tank 3 is realized by controlling the opening and closing of the vacuum valve 6 and the vacuum valve 7. In the above structure, by setting up a vacuum system connected to the heating glue tank 3, the gas discharged from the glue liquid in the heating glue tank 3 can be extracted or the gas filled into the heating glue tank can be used to crush and defoam the air bubbles on the glue surface, thereby improving the degassing efficiency of the glue liquid.

[0030] like Figure 2 As shown, when it is necessary to evacuate the heating glue tank 3, vacuum valve 6 is closed and vacuum valve 7 is opened. At this time, the air in the heating glue tank 3 is extracted under the action of vacuum pump 8. When vacuum valve 6 is opened and vacuum valve 7 is closed, another branch of Y-type vacuum tube 5 is connected to positive pressure air. Air is filled into the heating glue tank 3 through the other branch of Y-type vacuum tube 5 to break the air bubbles on the liquid surface. After the above process is repeated many times, the removal of glue gas is completed.

[0031] When the adhesive is degassed under vacuum, the liquid level rises to a certain position. After the liquid level sensor 17 senses this, it opens the vacuum valve 6 to introduce air into the heated adhesive tank 3 and crushes the bubbles that overflow from the adhesive. When the liquid level drops, the vacuum valve 6 closes and the vacuum system continues to pump air.

[0032] like Figure 3As shown, the specific structure of the lifting stirring device is as follows: The lifting stirring device includes a lifting cylinder 10 and a stirring motor 11. The lifting cylinder 10 is vertically arranged outside the heating glue tank 3, and the lower end of the lifting cylinder 10 is fixed to the vibration platform of the vibration base 2. The piston rod end of the upper end of the lifting cylinder 10 is fixedly connected to one end of the mounting plate 12, and the stirring motor 11 is fixed to the bottom surface of the other end of the mounting plate 12. The bucket cover 4 is fixedly connected to the lower end of the stirring motor 11, and the upper end of the stirring shaft 13, which is rotatably and sealingly connected to the middle of the bucket cover 4, is fixedly connected to the output shaft of the stirring motor 11. That is, the stirring shaft 13 is rotatably connected to the bucket cover 14 through a bearing, and the end caps above and below the bearings are sealed and fixedly connected to the corresponding end faces of the bucket cover 14. The lower end of the stirring shaft 13 is fixedly connected to the stirring paddle 14 located inside the heating glue tank 3. Specifically, a sealing gasket is provided on the bottom surface of the bucket cover 4 to press and seal against the upper edge of the heating glue tank 3. Figure 4 As shown, the stirring paddle 14 has a cylindrical structure with multiple square holes on its outer circumferential wall, which is adapted to the heating glue tank 3. In the above structure, a lifting stirring device including a lifting cylinder 10 and a stirring motor 11 is used. On the one hand, it controls the sealing state between the lid 4 and the heating glue tank 3, which facilitates the entry and exit of the glue liquid. On the other hand, the stirring motor 11 drives the stirring shaft 13 connected to the stirring paddle 14 in the heating glue tank 3 to rotate, which stirs and vents the glue liquid inside, providing conditions for improving the quality of the glue liquid. When glue liquid is added to or poured out of the heating glue tank 3, the lifting cylinder 10 can lift or lower the lid 4, which makes it convenient to remove the heating glue tank 3 or clamp it for sealing. Heating and stirring the glue liquid can more effectively and evenly stir the glue liquid, allowing the gas to escape, which is beneficial for removing the gas. The lid 4 is pressed down to the upper edge of the heating glue tank 3 by the lifting cylinder 10 and then sealed well.

[0033] like Figure 3 As shown, the heating glue tank 3 adopts an integral structure formed by a barrel body and an electric heating layer 18 provided on the outer wall of the barrel body; in the above structure, by setting a vibration base 2 on the support 1 and a heating glue tank 3 fixed on the vibration platform of the vibration base 2, the heating glue tank 3 heats the glue liquid inside evenly and then vibrates it through the vibration base 2. The glue liquid is provided with heating and vibration conditions, thereby forcing the residual gas in the glue liquid to overflow and better removing the gas in the glue liquid;

[0034] like Figure 5As shown, the specific structure of the vibration base 2 is as follows: The vibration base 2 includes a lower support 2-1 and a vibration cylinder 2-2. The lower support 2-1 is fixed on the bracket 1, and the lower end of the vibration cylinder 2-2 is fixed on the lower support 2-1. The vibration part at the upper end of the vibration cylinder 2-2 is fixedly connected to the support 2-3. Multiple spacers 2-5 are evenly distributed on the support 2-3 and fixedly connected to the bottom surface of the upper support 2-4. The heating glue tank 3 and the lifting stirring device are both located on the upper end surface of the upper support 2-4. Specifically, the upper support 2-4 is provided with L-shaped clamps 16 symmetrically distributed on both sides of the heating glue tank 3 and connected to the cylinder. The heating glue tank 3 is located between two L-shaped clamps 16, and the L-shaped clamps 16 clamp or release the heating glue tank 3 under the control of the cylinder. The vertical outer wall of the L-shaped clamps 16 facing the heating glue tank 3 is provided with a buffer pad. The heating glue tank 3 is placed on the vibrating base 2, and the pneumatic clamp clamps the heating glue tank 3. After most of the gas in the glue is removed by the vacuum system, the vibrating cylinder 2-2 drives the heating glue tank 3 to start vibrating up and down, causing the gas inside the glue to continuously overflow.

[0035] In practical work, in order to completely eliminate the gas in the adhesive, a comparison between high-frequency vibration and manual low-frequency vibration revealed that manual low-frequency up-and-down impact on the adhesive container was more likely to cause the gas in the adhesive to overflow. Therefore, using cylinder up-and-down vibration instead of manual up-and-down vibration can effectively remove the residual gas in the adhesive, thereby effectively improving the bonding quality of parts.

[0036] The support 1 is equipped with a control cabinet 15, and the control cabinet 15 is equipped with control buttons for controlling the start, stop or reversal of the vibration cylinder 2-2 in the vibration base 2, the lifting cylinder 10 in the lifting stirring device and the stirring motor 11, as well as controlling the on and off of the vacuum valve 6, vacuum valve 7 and vacuum pump 8 in the vacuum system.

[0037] This technical solution features a compact structure, small size, wide applicability, low cost, convenient use and adjustment, high control precision, high efficiency, and good product consistency. It can both heat the adhesive solution evenly and stir it, and quickly eliminate gas in the heated adhesive container. This solves the drawback of uncontrollable adhesive quality caused by manual degassing, replaces traditional manual operations, accurately controls various process parameters, and has high production efficiency. It can well meet the process requirements of eliminating adhesive gas during the bonding of various precision parts and optoelectronic products.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
