Abstract
The utility model discloses a chip pin pulling-out device which comprises a cuboid base. A row of protruding teeth protruding out of the upper surface of the base are arranged on the top of the base and are evenly distributed in a line, and the distances between the protruding teeth and the side face of the base are identical. By means of the chip pin pulling-out device, chip pins can be pulled out quickly, an operation worker can pull out 90 pins per minute, the problem that the chips pins are hard to pull out is solved, and production cost is reduced due to the fact that the chip pins are used as sensor welding pins. Two ends of the row of protruding teeth are respectively provided with anti-falling teeth, the probability that the protruding teeth are impacted by the outside is reduced, the protruding teeth are well protected, the structure is simple, and using is convenient.
Description
Technical field
The utility model relates to a kind of aid of using in the sensor manufacturing, specifically refers to a kind of plucking device of chip pin.
Background technology
Automobile wheel speed sensor mainly is made up of inductive head, wire harness and annex etc.The effect of inductive head be exactly be contained in automobile chassis on the target gear cooperate, the rotating speed of measured automobiles wheel partly is made up of coil, magnetic pole etc.On this basis, guarantee normal operation of sensor, sensor can reasonably be installed on the automobile chassis, its mounting means has a lot.Existing normally used a kind of wheel speed sensors is arranged is steel shell and a part that relies on the inductive head outside, i.e. resilient bushing cooperation is in the chassis the corresponding mounting hole of packing into.During the design sensor, in the middle of magnet steel, magnetic conductor need being combined in, magnetic conductor is an iron core, and coil forms the magnetic conduction coil around magnet steel and iron core.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, at first needs injection moulding one skeleton body, reinstalls iron core, magnet steel, reinstalls stopper at last, 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: pack into skeleton body-coiling-twine cotton thread-dress magnet steel-stopper gluing assembling-coil the end of a thread line tail to be wound on the capillary of iron core gluing.
The capillary of automobile sensor has two kinds: a kind of is the big capillary that is connected to the automobile sensor probe, its dimension scale is according to different model and different, common production method is to utilize copper material to shear, be worth by electroplating technique then, the applicant has invented new process units and new technology is produced this kind capillary; Another kind is the standard capillary, be used 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 himself cost of processing is higher, in order to reduce cost, the existing chip pin can be extracted can use, reduce cost with this, how to extract pin rapidly is comparatively difficult thing always.
The utility model content
The purpose of this utility model is to provide a kind of plucking device of chip pin, and the pin that solves present electronic chip is extracted the problem of comparison difficulty, uses the pin of electronic chip as the little capillary of automobile sensor, reaches the purpose that reduces cost.
The purpose of this utility model is achieved through the following technical solutions:
A kind of plucking device of chip pin comprises that integral body is the pedestal of cuboid, is provided with the double wedge that a row protrudes from pedestal upper surface at the pedestal top, and described double wedge is evenly distributed on the straight line, and identical apart from the lateral distance of pedestal.The integral body of pedestal is cuboid, made by bloom, 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 the plane, is used for being placed on workbench, and the top of pedestal is the plane, top planes is 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 be 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 about, roll, chip originally under the stopping of double wedge, makes pin come off in chip, so, not only simple to operate, and the speed of extracting is very fast, and operator's speed can reach 90 pieces/minute, solved the problem that chip pin is difficult to extract, be used as the sensor capillary with chip pin and reduced production cost.
Described double wedge integral body is cuboid.Further, adopt rectangular-shaped double wedge, during use with the long limit of double wedge perpendicular to chip itself, the short base of its length is contacted with chip itself, when having guaranteed the maximum external force that to bear between integral body and the pedestal, increased the distance between the double wedge, be conducive to pin is put between the double wedge.
The upper surface of described double wedge and the corner angle between the side are removed the back and are formed level and smooth cambered surface.Further, in order to guarantee user's safety, avoid sharp corner to scratch operating personnel's hand, adopt corner angle to remove the double wedge that the back forms level and smooth cambered surface, do not had sharp corner angle, increased operating personnel's comfortable feel degree, avoided scuffing.
Two ends at described row's double wedge are provided with the shatter-resistant tooth.Further, as further improvement of the utility model, adopt the version that the shatter-resistant tooth is set respectively at the two ends that double wedge is arranged, be conducive to reduce the possibility that double wedge is subjected to extraneous bump, protected double wedge well.
The utility model compared with prior art has following advantage and beneficial effect:
The plucking device of a kind of chip pin of 1 the utility model, top planes is 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 faced upward be 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 about, roll, chip originally under the stopping of double wedge, makes pin come off in chip, so, not only simple to operate, and the speed of extracting is very fast, and operator's speed can reach 90 pieces/minute, solved the problem that chip pin is difficult to extract, be used as the sensor capillary with chip pin and reduced production cost;
The plucking device of a kind of chip pin of 2 the utility model, adopt rectangular-shaped double wedge, during use with the long limit of double wedge perpendicular to chip itself, the short base of its length is contacted with chip itself, when having guaranteed the maximum external force that to bear between integral body and the pedestal, increased the distance between the double wedge, be conducive to pin is put between the double wedge;
The plucking device of a kind of chip pin of 3 the utility model adopts the version that the shatter-resistant tooth is set respectively at the two ends that double wedge is arranged, and is conducive to reduce the possibility that double wedge is subjected to extraneous bump, has protected double wedge well, and is simple in structure, easy to use.
