Abstract
The invention discloses a chip pin pulling device. The chip pin pulling device comprises a rectangular substrate, wherein a row of convex teeth protruding on the upper surface of the substrate are arranged on the top of the substrate and are uniformly distributed on one straight line; the distance from each convex tooth to the side surface of the substrate is the same. The chip pin pulling device is very high in pulling speed, the speed for pulling pins by an operator can be up to 90 pieces per minute, the problem that a chip pin is difficultly pulled out is solved, and the production cost is reduced by taking the chip pin as a sensor welding needle; due to the fact that the structural form that anti-falling teeth are respectively arranged at the two ends of the convex teeth is adopted, the probability that the convex teeth are collided is reduced, the convex teeth are well protected, and the chip pin pulling device is simple in structure and convenient to use.
Description
Technical field
The present invention relates to a kind of aid of using in sensor manufacturing, specifically refer to the plucking device of chip pin.
Background technology
Automobile wheel speed sensor is mainly comprised of inductive head, wire harness and annex etc.The effect of inductive head is exactly to coordinate with the target gear being contained on automobile chassis, and the rotating speed of measured automobiles wheel, is partly comprised of coil, magnetic pole etc.On this basis, guarantee normal operation of sensor, also must make sensor reasonably be installed on automobile chassis, its mounting means has a lot.Existing normally used to have a kind of wheel speed sensors be steel shell and a part that relies on inductive head outside, i.e. resilient bushing cooperation, packs in the corresponding mounting hole of chassis.During design sensor, in the middle of magnet steel, magnetic conductor need to being combined in, magnetic conductor is an iron core, and coil, around magnet steel and iron core, forms magnetic conduction coil.The variation of the coil-induced surrounding magnetic field of magnetic conduction, produces the signal of telecommunication, and this signal of telecommunication outputs to external device (ED) by capillary.The supporting mass of magnet steel, iron core, coil is called skeleton.Existing skeleton is split type skeleton, first needs injection moulding one skeleton body, reinstalls iron core, magnet steel, finally reinstalls stopper, forms skeleton; The technical process that forms sensing head is as follows: 1, processing parts: skeleton body, magnetic conductor, magnet steel, capillary, stopper, coil, cotton thread; 2, assembling process: iron core gluing packs skeleton body-coiling-twine cotton thread-dress magnet steel-stopper gluing assembling-coil the end of a thread line tail to be wound on capillary into.
The capillary of automobile sensor has two kinds: a kind of is the large capillary that is connected to automobile sensor probe, its dimension scale is according to different model and different, common production method is to utilize copper material to shear, then by electroplating technique, be worth, applicant has invented new process units and new technique is produced this kind of capillary; Another kind is standard capillary, for being connected to circuit board or other preferred circuit equipment, its structure is identical with common electronic chip pin, also can adopt the mode of oneself processing, but the cost that himself is processed is higher, in order reducing costs, existing chip pin can be extracted and can be used, with this, reduce costs, how to extract rapidly pin is comparatively difficult thing always.
Summary of the invention
The object of the present invention is to provide the plucking device of chip pin, the pin that solves current electronic chip is extracted more difficult problem, uses the pin of electronic chip as the little capillary of automobile sensor, reaches the object reducing costs.
Object of the present invention is achieved through the following technical solutions:
The plucking device of chip pin, comprises that integral body is the pedestal of cuboid, at pedestal top, is provided with the double wedge that a row protrudes from pedestal upper surface, and described double wedge is uniformly distributed point-blank, and identical apart from the lateral distance of pedestal.The integral body of pedestal is cuboid, by bloom, made, in order to reduce weight, also can make with rigid plastics, the size of its integral body and common palmistry are coincide, so that operating personnel are dominated by hand, the bottom of pedestal is plane, be used for being placed on workbench, the top of pedestal is plane, in top planes, be provided with row's double wedge, double wedge is neat, be arranged in a straight line equably, the distance of this air line distance pedestal top equates, electronic chip is faced upward and is placed on base top surface, its pin is all made progress, and chip contact base top surface itself, and allow the pin of chip between double wedge, operating personnel clamp chip pin with tweezers or nipper plier, firmly pull outward, must not be upper and lower, roll, chip is originally under the stopping of double wedge, pin is come off in chip, so, not only simple to operate, and the speed of extracting is very fast, operator's speed can reach 90 pieces/minute, solved the problem that chip pin is difficult to extract, with chip pin, be used as sensor capillary and reduced production cost.
Described double wedge integral body is cuboid.Further, adopt rectangular-shaped double wedge, during use by the long limit of double wedge perpendicular to chip itself, the shorter base of its length is contacted with chip itself, when having guaranteed the maximum external force that can bear between integral body and pedestal, increase the distance between double wedge, be conducive to pin to be put between double wedge.
The upper surface of described double wedge and the corner angle between side form level and smooth cambered surface after removing.Further, in order to guarantee user's safety, avoid sharp corner to scratch operating personnel's hand, adopt corner angle to remove the rear double wedge that forms level and smooth cambered surface, there is no sharp corner angle, increased operating personnel's comfortable feel degree, avoided scuffing.
Two ends at described row's double wedge are provided with shatter-resistant tooth.Further, as a further improvement on the present invention, adopt the two ends of arranging at double wedge that the version of shatter-resistant tooth is set respectively, be conducive to reduce double wedge and be subject to extraneous possibility of clashing into, protected well double wedge.
The present invention compared with prior art, has following advantage and beneficial effect:
The plucking device of 1 chip pin of the present invention, in top planes, be provided with row's double wedge, double wedge is neat, be arranged in a straight line equably, the distance of this air line distance pedestal top equates, electronic chip is faced upward and is placed on base top surface, its pin is all made progress, and chip contact base top surface itself, and allow the pin of chip between double wedge, operating personnel clamp chip pin with tweezers or nipper plier, firmly pull outward, must not be upper and lower, roll, chip is originally under the stopping of double wedge, pin is come off in chip, so, not only simple to operate, and the speed of extracting is very fast, operator's speed can reach 90 pieces/minute, solved the problem that chip pin is difficult to extract, with chip pin, be used as sensor capillary and reduced production cost,
The plucking device of 2 chip pins of the present invention, adopt rectangular-shaped double wedge, during use by the long limit of double wedge perpendicular to chip itself, the shorter base of its length is contacted with chip itself, when having guaranteed the maximum external force that can bear between integral body and pedestal, increase the distance between double wedge, be conducive to pin to be put between double wedge;
The plucking device of 3 chip pins of the present invention, adopts the two ends of arranging at double wedge that the version of shatter-resistant tooth is set respectively, is conducive to reduce double wedge and is subject to extraneous possibility of clashing into, and has protected well double wedge, simple in structure, easy to use.
