[0002] Some module products need to be filled with a specified type of glue, and the glue for many modules needs to be filled in a high temperature environment (45-100°C). In order to ensure that the glue filled inside the module is as full as possible, the bubbles in the glue need to be discharged with the help of a negative pressure environment during the filling process. It is relatively easy to meet any of the above requirements independently, but it is difficult to meet all of the above requirements at the same time and consider the repeated filling conditions.

[0004] In order to solve the above technical problems, the present invention discloses a negative pressure bubble removal circulation perfusion system in a high temperature environment, comprising: a solenoid valve assembly, a connector, a structural support, a negative pressure storage tank, a controller, a perfusion module, a base, a storage tank, a vacuum pump and a plastic pipe assembly;

[0005] The glue liquid is stored in a storage tank;

[0006] The filling module, the material storage tank and the vacuum pump are respectively fixed on the base;

[0007] The negative pressure storage tank is fixed to the base through a structural support;

[0008] The negative pressure storage tank, the filling module, the storage tank and the vacuum pump are connected through a plastic pipe assembly and a solenoid valve assembly;

[0009] The connector is connected to the solenoid valve assembly via a cable;

[0010] The controller is connected to the connector via a cable, and the on-off control of each solenoid valve in the solenoid valve assembly is achieved through the connector.

[0018] One end of the sixth plastic tube is connected to the negative pressure storage tank, one end of the seventh plastic tube is connected to the fourth solenoid valve, and one end of the ninth plastic tube is connected to the fifth solenoid valve; the other end of the sixth plastic tube, the other end of the seventh plastic tube and the other end of the ninth plastic tube are connected in series through a three-way joint;

[0019] The sixth solenoid valve is arranged between the negative pressure material storage tank and the material storage tank.

[0020] In the above-mentioned negative pressure bubble removal circulation perfusion system under high temperature environment, the ninth plastic tube is connected to the external atmospheric environment through the fifth solenoid valve.

[0021] In the above-mentioned negative pressure debubble circulation perfusion system under high temperature environment, the negative pressure environment of the negative pressure storage tank is provided by the vacuum pump through the fourth solenoid valve, the seventh plastic tube and the sixth plastic tube.

[0022] In the above-mentioned negative pressure bubble removal circulation perfusion system under high temperature environment, when the system performs perfusion work: the glue liquid is sucked out from the storage tank through the first plastic tube and then passes through the first solenoid valve, the glue liquid flows through the first solenoid valve and then passes through the second plastic tube and then passes through the second solenoid valve, the glue liquid is injected into the perfusion module after passing through the second solenoid valve, the glue liquid overflowing the perfusion module passes through the fourth plastic tube and then passes through the third solenoid valve, and the overflowed glue liquid flows into the negative pressure storage tank through the fifth plastic tube after passing through the third solenoid valve.

[0026] The present invention has the following advantages:

[0027] (1) The present invention discloses a negative pressure bubble removal circulation perfusion system in a high temperature environment. All components of the entire perfusion system through which the glue flows are integrated on a base and can be placed in a high temperature environment for high temperature perfusion. A continuous negative pressure state can then be provided in the high temperature environment, thereby improving the perfusion ratio and efficiency of the glue material in the module.

[0028] (2) The present invention discloses a negative pressure bubble removal circulation perfusion system under high temperature environment. Since the vacuum pump continuously provides a negative pressure environment for the system, and in order to ensure the amount of glue liquid perfusion inside the perfusion module, a period of perfusion is required after the glue liquid overflows the perfusion module. Therefore, a negative pressure storage tank is designed to temporarily store the overflowed glue liquid and prevent the glue liquid from flowing into the vacuum pump. At the same time, in order to improve the utilization rate of the glue liquid, a sixth solenoid valve is also provided to transfer the glue liquid in the negative pressure storage tank to the storage tank for reuse.

[0029] (3) The present invention discloses a negative pressure bubble removal circulation perfusion system in a high temperature environment. All operations of the perfusion system are realized through a controller to avoid manual operation in a high temperature environment.

[0030] (4) The present invention discloses a negative pressure bubble removal circulation perfusion system under high temperature environment, which is suitable for glue perfusion of other closed cavity structures. BRIEF DESCRIPTION OF THE DRAWINGS
