Embodiment

[0019] Such as figure 1 As shown, a method for removing pins of discarded chips in the present invention includes a cuboid base 1 as a whole, and a row of protruding teeth 2 protruding from the upper surface of the base 1 is arranged on the top of the base 1, and the protruding teeth 1 are in the shape of a whole Cuboid, the edges and corners between the upper surface and the side of the convex teeth 2 are removed to form a smooth arc surface, the convex teeth 2 are evenly distributed on a straight line, and the distance from the side of the base 1 is the same, at both ends of a row of convex teeth 2 Anti-fall teeth 3 are respectively provided, and the height of anti-fall teeth 3 is slightly higher than that of convex teeth 2. Meanwhile, the width and length of anti-fall teeth 3 are slightly larger than the width and length of convex teeth 2.

Abstract

The invention discloses a pin detaching method for waste chips. A cuboid base is adopted. A row of protruding teeth protruding out of the upper surface of the base are arranged at the top of the base and evenly distributed on the same straight line. The distances between the protruding teeth and the side face of the base are equal. By the adoption of the method, the pulling-out speed is high, the speed of an operator can reach 90 pieces per minute, the problem that pins of the chips are difficult to pull out is solved, and production cost is reduced by using the pins of the chips as welding pins of sensors; and by the adoption of the structural mode that anti-falling teeth are arranged at the two ends of the arranged protruding teeth, the possibility of external collision received by the protruding teeth can be lowered, the protruding teeth are well protected, the structure is simple, and use is convenient.

Description

technical field [0001] The invention relates to an auxiliary tool used in the sensor manufacturing industry, in particular to a method for removing pins of discarded chips. Background technique [0002] The automobile wheel speed sensor is mainly composed of induction head, wiring harness and accessories. The role of the induction head is to cooperate with the target gear installed on the chassis of the car to measure the speed of the car wheel, which is composed of coils, magnetic poles and other parts. On this basis, to ensure the normal operation of the sensor, the sensor must be properly installed on the chassis of the car, and there are many ways to install it. Now commonly used a kind of wheel speed sensor is to rely on the outer steel casing of the induction head to cooperate with a part, i.e. the elastic bush, and pack into the corresponding mounting hole of the chassis. When designing the sensor, it is necessary to combine the magnetic steel and the magnetic condu...
