Problems solved by technology

[0004] As the size of the product becomes smaller and smaller, the requirements for the proportioning accuracy and glue output accuracy of the automatic glue filling machine are getting higher and higher, especially for the fully enclosed module power supply. The curing situation cannot be known, and the existing technology cannot automatically detect the situation after the product is cured, so it can only be monitored at the glue filling end to ensure that the ratio of the automatic glue filling machine is always normal
However, most of the existing automatic glue filling machine glue delivery systems do not have flow monitoring. During the glue filling operation, the flow rate is often inaccurate due to many factors, and human operation errors often cause the product to fail to glue, resulting in a large number of scrapped products or customer complaints. question

Embodiment Construction

[0031] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Instructions attached figure 2 A structural schematic diagram of the present invention is provided,

[0033] For problem 2, the lack of real-time monitoring of the pressure in the storage tank, the glue filling machine of the present invention adds a pressure detection device 211 on the storage tank 21 to display the real-time pressure in the tank. The upper and lower limit pressure ranges can be set. When the actual pressure value is not within the set upper and lower limit ranges, the control system will send an alarm shutdown signal, and the equipment will perform an alarm shutdown action. The pressure detection device 211 is preferably an electronic pressure gauge. The electronic pressure gauge can be a conventional digital display pressure gauge, which is installed on the upper end of the curing agent storage tank and communic...

Abstract

A glue-pouring machine is used for mixing a main agent and a curing agent and then discharging pouring sealant, and comprises a main glue delivery system, an auxiliary glue delivery system, a vacuumizing motor and a mixing valve, wherein the main glue delivery system provides the main agent; the auxiliary glue delivery system provides the curing agent; the vacuumizing motor is used for carrying out vacuumizing on the main glue delivery system and the auxiliary glue delivery system; the main glue delivery system comprises a main barrel, a discharging valve, a main metering pump, a main motor and a main glue delivery tube; the discharging valve is arranged below the main barrel; the main motor drives the main metering pump; the main glue delivery tube is connected to the mixing valve from the main barrel; the auxiliary glue delivery system comprises an auxiliary barrel, an auxiliary discharging valve, an auxiliary metering pump, an auxiliary motor and an auxiliary glue delivery tube; the auxiliary discharging valve is arranged below the auxiliary barrel; the auxiliary motor drives the auxiliary metering pump; the auxiliary glue delivery tube is connected to the mixing valve from the auxiliary barrel; and a flow detecting device is arranged on the auxiliary glue delivery tube and is used for monitoring real-time flow of the curing agent in the auxiliary glue delivery tube. Compared with the prior art, the glue-pouring machine solves the problem that abnormal flow, proportion and nitrogen pressure of the automatic glue-pouring machine cannot be monitored.

Description

technical field [0001] The invention relates to a power module packaging process, in particular to an automatic glue filling machine suitable for the power module packaging process. technical background [0002] In the electronics industry, especially micro-power module power supplies, some products are encapsulated by glue filling. Due to the use environment and performance requirements of the products, there are corresponding requirements for the curing degree of the glue. [0003] Such as figure 1 As shown, it is a schematic diagram of the control principle of the existing glue filling machine, a glue filling machine, which is used to mix the main agent and the curing agent to output the potting glue, including the main glue delivery system 10 for providing the main agent, providing the curing agent The auxiliary glue conveying system 20, the vacuum motor 30 and the mixing valve 50 for vacuuming the main glue conveying system and the auxiliary glue conveying system, the ...
