1、 Brief introduction of design scheme

According to the characteristics of your company's products, a high cost performance welding equipment is designed. The TO46 / to56 sealing cap energy storage spot welding machine designed in this scheme has good sealing performance. The welding power supply part of the machine adopts capacitor energy storage discharge welding, which is mainly suitable for packaging and welding of high-power devices such as TO46 / to56, transistors, laser diodes, etc. The transmission part adopts pneumatic pressure, which can ensure enough welding pressure. The flatness of the upper and lower electrodes is ensured by the precise guidance of the four column ball mold. Welding operation is easy and reliable. It is widely used in electronic components industry. The capping machine has the functions of adjusting energy storage voltage, charging and discharging, pneumatic pressurization and pneumatic unloading. The machine adopts imported controllable silicon as charge and discharge control, stable and reliable action, perfect protection function, convenient adjustment of process parameters, safe and reliable operation, matching with vacuum gloves and nitrogen filling protection. It is widely used in sealing stone crystal resonator, monolithic crystal filter, clock controlled oscillator, laser diode and temperature compensation crystal oscillator, transistor photoelectric element and small-sized Thermal protector is the first equipment to improve the process of transistor manufacturing enterprises.

Workflow:

Manually place the workpiece in the left transfer box, then close the left chamber door, and then start the vacuum pump valve for vacuum evacuation; then open the left inner chamber door of the left box from the nitrogen box in the middle main box, put the workpiece into the main box, and weld and seal the cap under the protection of nitrogen; After all welding is completed, open the right chamber door in the main body box, put the welding sealed TO46 into the rightmost heating box for heating, and finally take out the finished product from the right heating box.

1. Fuselage: the bottom support structure is made of industrial sheet metal, and the surface is oxidized, sprayed and painted, which has a very beautiful appearance and is resistant to dirt; the box on the table is made of 304 stainless steel welding, which has the advantages of long service life, stable structure and strength; it provides enough stress support points and working platform for other action mechanisms.

2. Pressurization mechanism: the cylinder is used as the pressure source and controlled by high-quality imported solenoid valve.

3. Welding power supply: according to the product welding requirements, the capacitor energy storage spot welding machine is selected as the power supply to ensure the stable and strong welding current output of the whole machine and the reliability of the product welding.

4. Operation control system: PLC control circuit, 7 inch LCD touch screen, simple and intuitive operation.

5. Feeding mechanism The design adopts three sealing boxes connected together. The small box on the left side is the transfer door box (welding work pieces are put into the transfer door box first, and then the vacuum pump valve will be opened to drain the air inside). In the middle is a relatively large welding sealing box, which is filled with nitrogen, and the workpiece is welded under the protection of nitrogen (the workpiece in the welding chamber is transferred by the transfer bin) After welding, all the workpieces are transferred to the box of the heating chamber on the right side for heating, and finally the welded workpiece is taken out.

6. Operation system: PLC processor transmits various values, which is easy to operate and adjust welding position and speed.

7. Main features:

(1) Four axis guide pillar guide sleeve head, high precision;

(2) The lower electrode platform X-Y is adjustable;

(3) With dew point meter, with voltage detection;

(4) With heating and vacuumizing;

(5) All 304 stainless steel sealing chamber
