The test holes 362 have two, which are opened on the insulation test platform 361. Two probes 345 are located in one of the test holes 362. When the device is temporarily stopped on the insulation test platform 361, the probe 345 can quickly contact the pole piece of the device to complete the test. When the insulation test platform 361 can be prevented from being electrified, the probe 345 and the component are conducted with the device, and damage is avoided.
As a further improvement of the present invention, the insulating test platform 361 and the insulating plate 343 are ceramic plates.
The working principle is as follows:
Pouring the components into a hopper 407, and leaking the components in the hopper 407 onto the material guide groove 402; the vibrator 401 vibrates to make the components slide down rapidly, and finally fall onto the vibration screening material conveying disc 102, so that the components can be screened when passing through the mesh screen 403.
The vibratory screening and conveying tray 102 conveys the bottom surfaces of the components uniformly downward into the conveying chute 101.
The material conveying groove 101 continuously conveys materials; the rotary driving source 200 drives the rotary disc 210 to rotate, and when the material groove 211 is spliced with the material conveying groove 101, the components enter the material groove 211; then, the trough 211 drives the component to be transported, and when the component reaches a test position, the probe penetrates through the base 100 from the bottom of the base 100 and pricks on the component to be tested; meanwhile, the next material groove 211 rotates to the position of the material conveying groove 101; thus circulating.
the test driving source 312 drives the lifting block 314 to reciprocate; when the probe 345 rises, the test hole 362 is exposed and contacts with the component staying in the trough 211 above the probe to complete the test; when the probe 345 descends, the probe is collected into the testing hole 362, and at the moment, the components on the insulation testing platform 361 are replaced; according to the above cycle.
The tested components are separated through the screening unit.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
