Problems solved by technology

[0002] It is known that during the manufacturing process of capacitors and many electronic components, there are many electrolytes and impurities remaining on the surface and gaps that need to be removed to improve the quality of capacitors and electronic components. The traditional cleaning method of capacitors is to use artificial The cleaning operation method of single-barrel immersion and sieving in a solvent is to place the capacitor in a cleaning basket with meshes around it, soak it in a heated acid (alkali) solvent, then rinse it with water and dry it in an oven, but Because the cleaning solution and solvent are easy to produce volatile chemicals during the heating and cleaning process, which is harmful to the human body and causes environmental pollution, so the above method has high labor intensity, low work efficiency, and is easy to cause environmental problems.

Embodiment 1

[0048] After manually setting the time, temperature and pump valve switching sequence specified by the cleaning process on the contact film panel of the automatic control cabinet, the capacitors to be cleaned are placed in the cleaning basket, and the cleaning basket is sent into the cleaning and drying equipment by the feeding mechanism Enter the acid treatment box, soak in the acid treatment box with the pH value of the acid solution ≤ 2 and the temperature in the box at 40-70°C for 3-8 minutes, and then be thrown up and down at a frequency of 5-10 times / minute for 0.5-3 Minutes, after completion, deliquify and drain at a high position for 0.5-1.5 minutes; then enter the front and rear cylinders of the first rinse box and the second rinse box for rinsing, and the cleaning baskets are in the first rinse box and the second rinse box The front and rear cylinders are first soaked for about 1 minute, then thrown up and down for 4-6 minutes at a frequency of 5-10 times per minute, ...

Embodiment 2

[0050] After manually setting the time, temperature and pump valve switching sequence specified by the cleaning process on the contact film panel of the automatic control cabinet, place the capacitors to be cleaned in the cleaning basket, and the cleaning basket is sent from the feeding mechanism to the cleaning and drying equipment In the pre-washing box in the ultrasonic hot water pre-washing box, the ultrasonic wave is first turned on for 1.5-4 minutes, then stopped and then thrown up and down at a frequency of 5-10 times / minute for 2-6 minutes, and the temperature in the box is 40-70 ℃, the ultrasonic frequency is 20-50KHz; after the completion, drain water at a high position for 0.5-1.5 minutes; then send the cleaning basket into the ultrasonic alkali treatment box, first turn on the ultrasonic for 1-4 minutes, then stop and then 5-10 times / minute The frequency is thrown up and down for 2-6 minutes, the alkaline solution is a degreasing solution, the temperature is 45-65°C...

Abstract

The invention relates to a cleaning and drying device for a capacitor, which consists of a host machine and an electric control cabinet, wherein, the host machine comprises a feeding mechanism, a cleaning and rinsing device, a drying device, a discharging mechanism and an auxiliary liquid system which are sealed inside a box; the cleaning and rinsing device is provided with an acid or alkali processing box and one to four rinsing boxes in sequence; the drying device has a drying box; the electric control cabinet consists of a touch film panel of man-machine exchange and a PCL programmable controller. The invention has a low labor strength for operation personnel; as the cleaning and rinsing course is finished inside a sealed box, volatile chemical medicament generated by solution or solvent is discharged reasonably from a vent-pipe, thus improving the labor environment and facilitating the discharging and centralized treatment for waste gas. As water for rinsing can be reused, water is saved. Heat air inside a blast heater is discharged through an induced draft fan, resulting in a negative pressure inside the box, thus decreasing the drying temperature inside the capacitor, saving energy sources and avoiding effect on the capacitor quality under a drying state of a relative high temperature.
