Abstract

The invention embodiment relating to the electronic field provides an elastic pin detection device, which comprises a main body module. The main body module is internally provided with an air chamber and at least a row of vertical air vents; the air vents are positioned beneath the air chamber and communicated with the air chamber; the side wall of the main body module is provided with peepholes corresponding to the row of vertical vent holes; wherein, each peephole traverses the corresponding row of vertical air vents; each air vent is internally provided with a probe which can move up and down; the main body module is further provided with an air inlet hole communicated with the air chamber; when the probe is resisted to the top by the pin, the corresponding position of the probe and the peephole is provided with a gap. The detection device can detect whether the lengths of single-row and multi-row pins are normal and whether the quantities are normal. The detection device characterized by convenience and durability has the advantages of saving the electrical conductivity of the pins in detecting the pins and avoiding the elastic fatigue problem of springs.

Description

Flexible pin detection device

Technical field

The present invention relates to electronic applications, particularly a kind of flexible pin detection device that is used for pin senses.

Background technology

Whether at electronic applications, it is normal need to detect the pin that is used to be plugged on the coupling arrangement on the circuit board etc., because coupling arrangement is many, pin is many, and underproof phenomenon such as need special checkout equipment to detect pin length and whether to lack is to enhance productivity.The pin detection device of prior art comprises the optical fiber pin detection device, the electrical pins pick-up unit.

But the inventor finds in practice:

There is following defective in the optical fiber pin detection device: when pin is the multi coil pin, because the light of optical fiber can not penetrate pin, whether just can not be found defectiveness in the middle of being positioned at and with the pin of light on same straight line of optical fiber.So can only detect single, if having double or whether then can not detect some pins during the multi coil pin normal.

Whether the electrical pins pick-up unit to detect pin normal if having electric conductivity by pin, but because the easy carbon distribution of probe on the electrical pins pick-up unit causes probe to lose electric conductivity, and because probe is often to contact, rub with pin, wearing and tearing easily, the life-span is shorter.

Summary of the invention

The embodiment of the invention provides a kind of flexible pin detection device, can detect pins single, many rows, and need not to detect pin by the electric conductivity of pin, and is more convenient.

The embodiment of flexible pin detection device provided by the present invention is achieved through the following technical solutions:

A kind of flexible pin detection device, this device comprises main body module, be provided with air chamber and the vertical pore of at least one row in this main body module, this pore is positioned at the below of air chamber and communicates with this air chamber, the sidewall of this main body module is provided with the vertical corresponding observation through hole of pore with this row, an observation through hole crosses the corresponding with it vertical pore of a row, be equipped with in each pore can be up and down probe, also be provided with the gas hand-hole that communicates with air chamber on the main body module, when probe is pushed up up by pin, be provided with breach in probe and the corresponding position of observation through hole.

From technique scheme as can be seen, the flexible pin detection device that the embodiment of the invention provides is owing to detect each pin, whether the length of pin that can detect single, many rows is normal, whether quantity has disappearance, and need not to detect pin by the electric conductivity of pin, more convenient, there is not the elastic fatigue problem of spring yet, more durable.

Description of drawings

The structural representation of the flexible pin detection device that Fig. 1 provides for the embodiment of the invention;

The pore of the flexible pin detection device that Fig. 2 provides for the embodiment of the invention and the structural representation of probe.

Embodiment

Technical scheme is for a better understanding of the present invention described embodiment provided by the invention in detail below in conjunction with accompanying drawing.

See also Fig. 1 and Fig. 2, this flexible pin detection device comprises main body module 1, be provided with the vertical pore 14 of air chamber 12 and at least one row in this main body module 1, this pore 14 is positioned at the below of air chamber 12 and communicates with this air chamber 12, be respectively arranged with vertical pore 14 corresponding observation through holes 111 on the two side 11 of this main body module 1 with this row, an observation through hole 111 crosses the corresponding with it vertical pore 14 of a row, be equipped with in each pore 14 can be up and down probe 2, also be provided with the gas hand-hole 13 that communicates with air chamber 12 on the main body module 1, this flexible pin detection device feeds gas by gas hand-hole 13, air chamber 12 is communicated with pore 14, form pneumatic spring with probe 2.The pin 31 that probe 2 is connected on the device 3 pushes up when coming up, and is provided with breach 21 in probe and observation through hole 111 corresponding positions.

On observation through hole 111, install optical fiber, when detecting pin 31, this flexible pin detection device moves downward, pin 31 on each pore 14 corresponding connector 3, (there is not disappearance if each pin 31 is all normal, non-cracking), pore 14 middle probes 2 will be come by jack-up, because when probe 2 is connected pin 31 top on the device 3 and comes up, be provided with breach 21 with observation through hole 111 corresponding positions, the breach 21 of each row's probe is at sustained height, the light that optical fiber sends is by passing the breach 21 that is positioned at sustained height from observation through hole 111, reach the observation through hole 11 of the opposite side of main body module 1, as long as a pin 31 disappearance arranged or ruptured, just having corresponding with it probe 2 is not come by jack-up, like this because the breach on this probe 2 does not reach the position of corresponding with it observation through hole 111, the light that optical fiber sends is just blocked by the probe 2 of pin 31 correspondences of this disappearance or fracture, can not pass observation through hole 111, just can detect the pin of damage (disappearance or fracture).In the time need not detecting, by the effect of air pressure, probe 2 can be got back to the bottom of pore 14 rapidly.

Further, insert air for convenience, the gas hand-hole 13 that is used to accept outside air is arranged on the top of main body module 1.

Further, vertical pore 14 is three rows, and the observation through hole 111 corresponding with each vent port 14 is three altogether, observation for convenience and operation, and three observation through holes 111 are not on same straight line.

Further, probe 2 is a draw point, prevents to be worn, and serviceable life is longer.

Further, main body module 1 is steel and is square, prevents to be worn and to be convenient to operation and installation.

Further, sidepiece, top or bottom that can also main body module 1 also be provided with fixed screw holes, so that this main body module is fixed on other the equipment or fixed object.

More than a kind of flexible pin detection device that the embodiment of the invention provided is described in detail, for one of ordinary skill in the art, thought according to the embodiment of the invention, part in specific embodiments and applications all can change, in sum, this description should not be construed as limitation of the present invention.
