[0002] Power electronic devices, also known as power semiconductor devices, are high-power electronic devices mainly used in the power conversion and control circuits of power equipment. Electronic components must be interconnected to form an electronic circuit with a specific function, such as amplifiers, radio receivers, and oscillators.

However, during the production of the adhesive, the adhesive may contain gas, resulting in a certain amount of air bubbles in the adhesive. If the air bubbles are applied to the surface of the electronic components along with the adhesive, the quality of the adhesive layer will directly affect the heat dissipation performance and insulation reliability of the device.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-5 As shown, a glue-applying mechanism for manufacturing power electronic components includes a glue-dispensing pipe 1, with one end of the glue-dispensing pipe 1 connected to a first connecting hose 2, and the other end of the first connecting hose 2 connected to a vibrating pipe 3 that discharges glue gas through vibration.
[0022] The other end of the vibrating tube 3 is connected to a second connecting hose 4, and the other end of the second connecting hose 4 is connected to a glue injection head 5. A fixing bracket 6 is fixed on the surface of the glue injection head 5, and the other end of the fixing bracket 6 is fixed on the surface of the glue delivery tube 1.
[0023] A vibration mechanism 7 is provided on one side of the surface of the glue delivery tube 1 to cause the vibrating tube 3 to vibrate. The vibration mechanism 7 includes a motor 71 fixed to one side of the surface of the glue delivery tube 1 and a force-receiving block 75 fixed around the surface of the vibrating tube 3. A first gear 72 is fixed to the output shaft of the motor 71, a second gear 73 is fixed to the inner cavity of the first gear 72, and several pushing blocks 74 are fixed to the inner cavity of the second gear 73. The pushing blocks 74 and the force-receiving block 75 work together. Under the action of the motor 71, the first gear 72 rotates, and the second gear 73 meshing with the surface of the first gear 72 causes the pushing blocks 74 to work, thereby enabling the pushing blocks 74 to vibrate. Under the action of the force block 75, the force block 75 is squeezed, and under the action of several push blocks 74 and force block 75, the vibrating tube 3 can vibrate. The surface of the second gear 73 is provided with a limit ring 9, and a fixing rod 8 is fixed on the surface of the limit ring 9. The other end of the fixing rod 8 is fixed to the surface of the glue delivery tube 1, so that the rotation of the second gear 73 is limited and the stability of the second gear 73 when rotating is improved. The motor 71 is a servo motor and has a built-in brake device. Under the action of the motor 71, the accuracy of the motor 71 rotation can be improved, and under the action of the brake device, the second gear 73 can be stably stopped at the designated position.
[0024] A gas outlet mechanism 10 is provided on one side of the surface of the glue delivery tube 1 to cooperate with the vibration mechanism 7. The gas outlet mechanism 10 includes several connecting air pipes 101 connected to the surface of the glue delivery tube 1. A filter block 102 is fixed in the inner cavity of the connecting air pipe 101. The other end of the connecting air pipe 101 is connected to an exhaust pipe 103. In this embodiment, by setting up the connecting air pipe 101, the filter block 102 and the exhaust pipe 103, the glue liquid can be blocked under the action of the filter block 102, so that the discharged gas flows out through the connecting air pipe 101 and the exhaust pipe 103, thereby improving the practicality of the device. The filter block 102 is made of ceramic filter sheet with a pore size of 5-10μm, which allows gas to pass through but blocks liquid.
[0025] When applying adhesive to electronic components through the glue delivery tube 1 and the glue dispensing head 5, the operator can use the vibration mechanism 7. Under the action of the vibration mechanism 7, the vibrating tube 3 vibrates, thereby causing the adhesive liquid inside the vibrating tube 3 to vibrate and achieve the purpose of expelling the gas in the adhesive liquid. In addition, the gas venting mechanism 10 can assist in the gas venting, improving the practicality of this device.
[0026] Working principle: When applying adhesive to power electronic devices, the adhesive can be applied to the designated location through the first connecting hose 2, the vibration tube 3, the second connecting hose 4, and the dispensing head 5 under the action of the dispensing tube 1, thereby participating in the manufacturing of power electronic devices.
[0027] When the adhesive passes through the vibrating tube 3, the operator can use the motor 71. Under the action of the motor 71, the first gear 72 rotates, and the second gear 73 meshing with the surface of the first gear 72 causes the push block 74 to work, so that the push block 74 and the force block 75 come into contact. Under the action of the force block 75, the vibrating tube 3 vibrates, and the adhesive vibrates. Under the action of the vibrating tube 3, the air in the adhesive is expelled, avoiding the presence of air bubbles in the adhesive, which would lead to an increase in local thermal resistance.
[0028] The gas moves upward and can then pass through the filter block 102. Under the action of connecting the gas pipe 101 and the exhaust pipe 103, it is discharged outward to achieve the purpose of exhaust.
