Description

Technical Field

[0001] The present application relates to the technical field of glue bubble removal devices, and in particular to an epoxy resin glue bubble removal device. Background Art

[0002] Epoxy resin glue has been widely used in electronics, electrical, machinery and other fields due to its excellent electrical insulation properties, mechanical properties and bonding strength.

[0003] However, in actual application, bubbles are easily introduced due to the stirring operation during the preparation process. The presence of these bubbles will affect the quality and reliability of the product. Therefore, debubbling becomes an indispensable process in the production of epoxy resin glue and is crucial to improving product quality.

[0004] Currently, existing technologies for removing bubbles from epoxy resin glue primarily include the static method and the vacuum method. The static method involves pouring the epoxy resin glue into a container and letting it sit naturally to allow bubbles to escape. This method is not limited by equipment and is suitable for small-batch production. The vacuum method uses a vacuum pump to evacuate the interior of the container to accelerate bubble release.

[0005] Although the various current bubble removal methods can reduce the bubble content to a certain extent, none of them can effectively remove all bubbles in the glue, especially in deep containers. It is difficult to achieve complete exhaust simply by stirring and then letting it stand or simply vacuuming. Utility Model Content

[0038] The vacuum assembly 140 includes a vacuum pump 141 and a vacuum tube 142. The vacuum pump 141 can be a water ring vacuum pump 141 or a rotary vane vacuum pump 141 with high-efficiency vacuum extraction capability.

[0041] In addition, a pressure sensor 160 is included for detecting the gas pressure in the tank body 110. This information can be used to feedback the working status of the vacuum component, thereby adjusting the working parameters of the vacuum pump 141 in time to ensure the best effect of the bubble removal process.

[0042] The pressure sensor 160 is a high-precision pressure sensor 160 installed on the outer wall of the tank body 110. The detection end of the pressure sensor 160 is embedded in the tank body 110, which can accurately monitor the pressure changes in the tank body 110. By connecting to the control system, the pressure sensor 160 can feed back the measured pressure value to the control system, and the control system automatically adjusts the working state of the vacuum pump 141 based on this information. For example, when the pressure in the tank body 110 is lower than the preset value, the control system will command the vacuum pump 141 to increase the pumping speed to achieve a better exhaust effect; conversely, when the pressure in the tank body 110 reaches or exceeds the preset value, the control system will command the vacuum pump 141 to slow down the pumping speed, thereby preventing the internal pressure of the tank body 110 from being too low; similarly, the speed at which the drive structure 114 drives the plunger cover 130 to move can also be adjusted.
