Embodiment 1

[0029] see Figure 1-3 , a metallized film capacitor core heat treatment process, comprising the steps of:

[0030] Step 1: The neatly arranged capacitor cores are conveyed to the positioning pipe 13 through the feeding pipe 10, and the electric telescopic rods 12 on both sides of the horizontal side of the feeding box 11 are started to move simultaneously, and the output end linkage piston pushes the capacitor cores, Thus, the capacitor core is slid onto the insertion rod 9, and the insertion rod 9 is made of copper material with good heat conduction;

[0031] Step 2: Start the external drive mechanism to operate, and the chain 7 is driven and turned through the gear plate 6. Through the operation of the electric control box, the movement speed of the chain 7 is adjusted, and the chain 7 and the insertion rod 9 are always kept in a horizontal state. Because the total length of the chain 7 arranged inside the first heating box 1, the second heating box 3, the first incubating...

[0038] see Figure 1-3 , a metallized film capacitor core heat treatment process, comprising the steps of:

[0039] Step 1: The neatly arranged capacitor cores are conveyed to the positioning pipe 13 through the feeding pipe 10, and the electric telescopic rods 12 on both sides of the horizontal side of the feeding box 11 are started to move simultaneously, and the output end linkage piston pushes the capacitor cores, Thus, the capacitor core is slid onto the insertion rod 9;

[0040] Step 2: Start the external drive mechanism to operate, and the chain 7 is driven and turned through the gear plate 6. Through the operation of the electric control box, the movement speed of the chain 7 is adjusted, and the chain 7 and the insertion rod 9 are always kept in a horizontal state. Because the total length of the chain 7 arranged inside the first heating box 1, the second heating box 3, the first incubating box 2 and the second incubating box 4 is different, thereby realizing that th...

Embodiment 3

[0047] The heating tubes 5 inside the first heating box 1, the second heating box 3, the first incubating box 2 and the second incubating box 4 have different powers. The heating temperature of the heating tubes 5 in the first heating box 1 is 90°C. The temperature of the heating pipe 5 in the box 2 is 95°C, the temperature of the heating pipe 5 in the second heating box 3 is 120°C, the temperature of the heating pipe 5 in the second incubator 4 is 125°C, the first heating box 1 and the second heating box 3 The middle chain 7 has the same length, the length of the chain 7 in the first incubator 2 is less than the length of the chain 7 in the second incubator 4, the running time of the chain 7 in the first heating box 1 and the second heating box 3 is 3.5h, and the first incubator The running time in 2 is 3.5 hours, and the running time in the second incubator 4 is 4 hours.

Abstract

The invention discloses a metallized film capacitor core heat treatment processing technology. The technology comprises the steps of 1, feeding; 2, operating a chain mechanism; 3, carrying out heat treatment in a first heating box; 4, carrying out heat treatment in a first heat preservation box; 5, carrying out heat treatment in a second heating box; and 6, carrying out heat treatment in a second heat preservation box, and naturally cooling. According to the invention, the capacitor core is transmitted through the chain, the capacitor core is in a suspended state in the chain, and a plug rod has good thermal conductivity, so that the problems of corrugation and aging of the capacitor core due to external hot and internal cold and unbalanced heating are avoided, the thermal shrinkage balance of the capacitor core is maintained, and the electrical performance and thermal stability of a product are ensured; and through the continuous chain mechanism and the heating box and the heat preservation box which are attached to each other, the heat treatment process time is shortened, the heat treatment efficiency is improved, heat dissipation is reduced, then energy consumption is reduced, and due to the fact that continuous step-by-step heating is adopted, the product quality is high.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a heat treatment process for metallized film capacitor cores. Background technique [0002] There are many types of capacitors depending on the medium, such as: electrolytic capacitors, paper capacitors, film capacitors, ceramic capacitors, mica capacitors, air capacitors, etc. But the most frequently used ones in audio equipment are electrolytic capacitors and film capacitors. Electrolytic capacitors are mostly used in places that require a large capacitance, such as the filter capacitor of the main power supply, which is used for storing electric energy in addition to filtering. Film capacitors are widely used in the cross-connection of analog signals and the bypass of power supply noise. [0003] The heat conduction inside and outside the existing capacitor core is unbalanced, and the metallized film on the outer ring is wrinkled and aging due to excessive heat treatment ...
