Description

Conductor pinhole detection device

This invention relates to a conductor pinhole detection device, especially a conductor pinhole detection device that can save detection time and cost.

Traditionally, when detecting whether the paint film on the conductor has pinholes or damage, it is necessary to prepare a basin, a test solution, a conductor, an auxiliary conductor, an AC and DC power supply, a chuck, and a timer. When testing, immerse the conductor in the basin containing the test solution, and expose both ends of the conductor to the liquid surface, scrape off the insulating film of 1 cm long from one end of the conductor, and pass the negative output of the AC/DC power supply through the The clip is placed on the end of the conductor where the insulating film has been scraped off. In addition, the insulating film of 1 cm long is scraped off at both ends of the auxiliary conductor. The positive output passes through the clip to clamp one end of the auxiliary conductor and the other end of the auxiliary conductor. Immerse in the test solution to form a loop. After the above process is completed, turn on the power for one minute and observe the conductor immersed in the test solution. If there is a pinhole on the conductor, there will be a purple-red haze phenomenon. If there are two or more pinholes on the conductor , the quality of the conductor is judged to be unqualified.

Traditional conductor pinhole detection has quite a few problems:

1. In each test, the power plug needs to be repeatedly inserted and unplugged, and the power transmission time needs to be manually set.

2. During the detection process, in addition to observing whether there is a purple-red fog on the surface of the conductor, it is also necessary to pay attention to whether the power transmission time on the timer has reached one minute.

3. The positive and negative output clamps of the AC and DC power supply are easy to be clamped wrongly and cause the detection failure.

4. The color of the pot is not a light color, so it is quite close to the color of the conductor and the color of the purple-red haze generated when the conductor has pinholes, so it is difficult to observe whether the conductor is qualified.

5. The basin containing the inspection solution needs to be removed every week for cleaning and replacement of the inspection solution, which increases the fatigue of the personnel performing the inspection.

6. The time and labor costs required for testing are quite high.

Based on the above reasons, there is still room for improvement in the traditional conductor pinhole detection. In view of this, the creator is actively researching, adding years of experience in related product research and development, and through continuous testing and improvement, finally developed this creation. .

The main purpose of this creation is to provide a conductor pinhole detection device, which can solve various problems of traditional conductor pinhole detection, so as to save the time and labor cost of conductor pinhole detection.

In order to achieve the above purpose, the present invention provides a conductor pinhole detection device, which includes a main body, an upper cover is installed on the upper part of the main body, a front cover is installed at the front end of the main body, and an upper space is formed in the main body corresponding to the upper cover, and the lower space corresponds to the front cover, the upper front edge of the main body is provided with a control part adjacent to the upper cover, the control part has a power switch, a voltmeter, an electronic timer and two status indicators; a detection slot , which is installed in the upper space of the main body, and a discharge valve is installed at the lower part of the detection tank, and the discharge valve is located in the lower space.

The conductor pinhole detection device also has an AC and DC power supply, the positive output of which is fixed to one end of the auxiliary conductor also set in the conductor pinhole detection device, and the negative output is connected with a clip, the clip is clamped on One end of the conductor to be tested, and one end of the conductor needs to be scratched In addition to 1 cm long insulating film.

When testing whether there is a pinhole on the conductor, the testing tank is filled with a testing solution, the conductor is immersed in the testing tank, and the negative output of the AC and DC power supply is clamped on the conductor through the clip, and the insulation has been scraped off. this end of the membrane. After completion, power on the conductor for one minute and observe the conductor. If there is a pinhole on the conductor, there will be a purple-red haze phenomenon. If there are two or more pinholes on the conductor, the quality of the conductor is judged. Failed.
