2) if the first current detecting instrument 271 and the second current detecting instrument 272 all bright, then illustrate that the height of pin 110 is less than the first preset length of the first conducting probe 241, is less than or equal to the second preset length of the second conducting probe 242.Concrete can be, when the height of pin 110 is less than the second preset length of the first preset length of the first conducting probe 241 and the second conducting probe 242, because the first conducting probe 241 and the second conducting probe 242 are respectively equipped with the first rebounding mechanism and the second rebounding mechanism with horizontal test rod 230 junction, therefore when the first conducting probe 241 contacts and is subject to power upwards with the first conductivity detection unit 261 that detection base 210 is oppositely arranged respectively with the second conductivity detection unit 262 with the second conducting probe 242, first conducting probe 241 and the second conducting probe 242 can be compressed, make the top contact of the pin 110 that must detect to horizontal test rod 230, now the first current detection circuit and the second current detection circuit conducting, and then first has electric current to pass through in current detection circuit and the second current detection circuit, first current detecting instrument 271 and the second current detecting instrument 272 all brighten.Wherein, the second preset length equaling the second conducting probe 242 when pin 110 and the second preset length being less than the second conducting probe 242 unlike, second conducting probe 242 is not subject to power upwards when contacting with the second conductivity detection unit 262 that detection base 210 is oppositely arranged, the second conducting probe 242 is not compressed.
3) if the first current detecting instrument 271 is bright, and the second current detecting instrument 272 does not work, then illustrate that the height of pin 110 is less than or equal to the first preset length of the first conducting probe 241, and be greater than the second preset length of the second conducting probe 242.Concrete can be, when the height of pin 110 is less than or equal to the first preset length of the first conducting probe 241, first conducting probe 241 contacts with the first conductivity detection unit 261 that detection base 210 is arranged, first current detection circuit conducting, and the height of pin 110 is greater than the second preset length of the second conducting probe 242, second conducting probe 242 does not contact with the second conductivity detection unit 262 that detection base 210 is arranged, the non-conducting of second current detection circuit, and then first current detecting instrument 271 bright, and the second current detecting instrument 272 does not work.
It should be noted that, when preset difference value between the first preset length and the second preset length is set to the error allowed band of height of pin, occur that the first current detecting instrument 271 is bright, and the situation that the second current detecting instrument 272 does not work, then illustrate that height of pin is approximately equal to the first preset length, meets the requirements.
The utility model embodiment is by comparing pin 110 height on worktable 120 with the first preset length of the first conducting probe 241 and the second preset length of the second conducting probe 242, from the light on and off of the first current detecting instrument 271 and the second current detecting instrument 272, the height drawing pin 110 on worktable 120 whether in preset range and which pin 110 not in preset range, when the first current detecting instrument is bright, second current detecting instrument does not work, the requirement of height of pin coincidence measurement is described, ensure that the high consistency of all pins 110 on worktable 120, solve the existing problem to the mode spended time length that the consistance of pins 110 all on worktable 120 detects, and avoid the reading error produced when adopting existing metering system to measure pin 110, improve work efficiency.
Preferably, detect base 210 to make for conductive material, detect base 210 and be multiplexed with the first conductivity detection unit 261 and the second conductivity detection unit 262, so just do not need to arrange separately the first conductivity detection unit 261 and the second conductivity detection unit 262 on detection base 210, save manufacturing process steps.
