[0002] With the advancement and development of science and technology, mechanical products are gradually replaced by electronic and optoelectronic products. To ensure product quality, electronic and optoelectronic products use corresponding glue to bond optical devices, electronic devices, optical fibers, etc. during assembly. However, when there is gas in the glue, bubbles will be generated in the glue during bonding. With the long-term effect of the bubbles, optical path failures (such as optical fiber coupling deviation, optical fiber fusion point quality, etc.) and circuit failures will occur, thus affecting product performance.

[0003] In production, when precision parts need to be glued, the quality requirements for the glue are high. The entire glue layer is required to have high strength and sealing, and there must be no bubbles. In order to ensure the quality of the glue, the prepared glue needs to be heated, stirred and vacuum degassed before each bonding. However, due to the high viscosity of the prepared glue, simple vacuum degassing cannot meet the process requirements, and artificial impact vibration must be used to ensure that the gas in the glue is removed as much as possible. There are many human uncertainties in this process, and it can only be operated by the operator based on experience. The quality of the glue has certain uncontrollable situations. Therefore, in order to solve the above technical problems, it is necessary to make improvements. Summary of the invention

[0028] A small glue liquid degassing device comprises a bracket 1, wherein a vibration base 2 is provided at the upper end of the bracket 1, and a heated glue barrel 3 is detachably clamped and fixed on the vibration platform of the vibration base 2, and the glue liquid inside the heated glue barrel 3 is vibrated under the vibration of the vibration base 2, a lifting and lowering stirring device arranged on the vibration platform of the vibration base 2 is rotationally sealedly connected to the middle part of a barrel cover 4 detachably sealed at the upper end of the heated glue barrel 3, and a stirring part of the lifting and lowering stirring device extends into the heated glue barrel 3 and stirs the glue liquid filled therein, a joint at the upper end of the heated glue barrel 3 is connected to a vacuum system, and the vacuum system extracts the gas discharged from the glue liquid in the heated glue barrel 3 or the gas filled in the heated glue barrel 3 crushes and defoams the bubbles on the glue surface, and a liquid level detection element is provided on the heated glue barrel 3 for detecting the upper liquid level of the glue liquid therein; the liquid level detection element adopts a liquid level sensor 17.

[0029] The specific structure of the vacuum system is as follows: the vacuum system includes a Y-shaped vacuum tube 5, a vacuum valve 1 6 and a vacuum valve 2 7. The main line of the Y-shaped vacuum tube 5 is connected to the air inlet of the vacuum pump 8 arranged inside the bracket 1, and the vacuum valve 2 7 is installed on the main line of the Y-shaped vacuum tube 5. A vacuum gauge 9 is installed on one of the branches of the Y-shaped vacuum tube 5 that is connected to the joint at the upper end of the heated glue barrel 3, which is convenient for vacuum measurement of the heated glue barrel 3. The vacuum valve 1 6 is installed on the other branch of the Y-shaped vacuum tube 5, and the switching of the vacuum state or the inflation state in the heated glue barrel 3 is realized by controlling the on and off of the vacuum valve 1 6 and the vacuum valve 2 7. In the above structure, by setting a vacuum system connected to the heated glue barrel 3, the gas discharged from the glue liquid in the heated glue barrel 3 can be extracted or the bubbles on the glue surface can be crushed and defoamed by the gas filled in the heated glue barrel, thereby improving the degassing efficiency of the gas in the glue liquid.

[0030] like Figure 2 As shown, when the heated glue barrel 3 needs to be evacuated, the vacuum valve 1 6 is closed and the vacuum valve 2 7 is opened. At this time, the air in the heated glue barrel 3 is extracted under the action of the vacuum pump 8; when the vacuum valve 1 6 is opened and the vacuum valve 2 7 is closed, the other branch of the Y-shaped vacuum tube 5 is connected to the positive pressure air, and the air is filled into the heated glue barrel 3 through the other branch of the Y-shaped vacuum tube 5 to break the bubbles on the liquid surface. After the above process is repeated for many times, the removal of the glue liquid gas is completed;

[0031] When the glue liquid is degassed in vacuum, the glue liquid level rises to a certain position. After the liquid level sensor 17 senses it, the vacuum valve 16 is opened to introduce air into the heated glue barrel 3, and the bubbles overflowing from the glue liquid are crushed. When the glue liquid level drops, the vacuum valve 16 is closed, 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 barrel 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 barrel cover 4 is fixedly connected to the lower end of the stirring motor 11, and the upper end of the stirring shaft 13 rotatably connected to the middle part of the barrel 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 barrel cover 14 through a bearing, and the end covers above and below the bearing that are sealed and fixedly connected to the corresponding end surfaces of the barrel cover 14, and the lower end of the stirring shaft 13 is fixedly connected to the stirring paddle 14 located in the heating glue barrel 3; specifically, a sealing gasket that is pressed and sealed with the upper edge of the heating glue barrel 3 is provided on the bottom surface of the barrel cover 4; as shown Figure 4 As shown, the stirring paddle 14 adopts a cylindrical structure with multiple square holes on the outer circumferential wall and is adapted to the heated glue barrel 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, the sealing state of the barrel cover 4 and the heated glue barrel 3 is controlled to facilitate the glue liquid to enter and exit the heated glue barrel, and on the other hand, the stirring shaft 13 connected to the stirring paddle 14 in the heated glue barrel 3 is driven by the stirring motor 11 to rotate and stir and exhaust the glue liquid inside, thereby providing conditions for improving the quality of the glue liquid; when adding or pouring glue liquid into or out of the heated glue barrel 3, the lifting cylinder 10 can lift or lower the barrel cover 4 to facilitate the removal or clamping of the heated glue barrel 3 and sealing; heating and stirring of the glue liquid can more effectively and evenly stir the glue liquid, so that the gas overflows, which is conducive to removing the gas, wherein the barrel cover 4 is pressed down to the upper edge of the heated glue barrel 3 by the lifting cylinder 10 and is well sealed with it.

[0033] like Figure 3 As shown, the heating glue barrel 3 adopts an integral structure formed by a barrel body and an electric heating layer 18 arranged on the outer wall of the barrel body; in the above structure, by arranging a vibration base 2 on the bracket 1 and fixing the heating glue barrel 3 on a vibration platform of the vibration base 2, the heating glue barrel 3 is vibrated by the vibration base 2 under the premise of uniformly heating the internal glue liquid, and 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 base 2-1 and a vibration cylinder 2-2, the lower support base 2-1 is fixed on the bracket 1, and the lower end of the vibration cylinder 2-2 is fixed on the lower support base 2-1, the vibration part of the upper end of the vibration cylinder 2-2 is fixedly connected to the support base 2-3, and a plurality of spacers 2-5 fixedly connected to the bottom surface of the upper support base 2-4 are evenly distributed on the support base 2-3, and the heating glue barrel 3 and the lifting stirring device are both arranged on the upper end surface of the upper support base 2-4; specifically, the upper support base 2-4 is provided with L-shaped clamps 16 symmetrically distributed on both sides of the heating glue barrel 3 and connected to the cylinder, and the heating glue barrel 3 is located between the two L-shaped clamps 16, and the heating glue barrel 3 is clamped or loosened by the L-shaped clamp 16 under the control of the cylinder, and a buffer pad is provided on the vertical outer wall of the L-shaped clamp 16 facing the heating glue barrel 3. The heated glue barrel 3 is placed on the vibration base 2, and the pneumatic clamp clamps the heated glue barrel 3. When most of the gas in the glue liquid is extracted by the vacuum system, the vibration cylinder 2-2 drives the heated glue barrel 3 to start vibrating up and down, so that the gas inside the glue liquid continuously overflows.

[0035] In order to completely eliminate the gas in the glue liquid in actual work, high-frequency vibration is used to compare with manual low-frequency vibration. It is found that manual low-frequency up and down impact on the glue barrel is more likely to cause the gas in the glue liquid to overflow. Therefore, the up and down vibration of the cylinder is used instead of manual up and down vibration. It can effectively overflow the residual gas in the glue liquid, thereby effectively improving the bonding quality of parts.

[0036] The bracket 1 is provided with a control cabinet 15, and the control cabinet 15 is provided 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 and the stirring motor 11 in the lifting stirring device, and controlling the on and off of the vacuum valve 1 6, the vacuum valve 2 7 and the vacuum pump 8 in the vacuum system.

[0037] The technical solution has the advantages of compact structure, small size, wide applicability, low cost, easy use and adjustment, high control accuracy, high use efficiency and good product consistency. It can not only heat the glue evenly and then stir it, but also quickly eliminate the gas in the heated glue barrel, thus solving the problem of uncontrollable glue quality caused by manual degassing, replacing traditional manual operations, accurately controlling various process parameters, and having high production efficiency. It can well meet the process requirements for eliminating glue gas during the bonding process of various precision parts and optoelectronic products.

[0038] It will be apparent to those skilled in the art that the 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 the spirit or essential features of the invention.
