Detection fixture for wire foot

Abstract

The invention discloses a detection fixture for a wire foot. The detection fixture comprises a circuit board bracket, a laser emitting end, a laser receiving end, a first slider, a second slider, a crossbar and a buzzer. The circuit board bracket has a groove type, and the groove type is favorable for the placement of the circuit board. The laser emitting end is mounted above a side of the circuitboard bracket. The laser receiving end is symmetrically mounted above the other side of the circuit board bracket. A first guide rail and a second guide rail are respectively arranged on the left andright sides of the circuit board bracket. The first slider is mounted in the first guide rail. The second slider is mounted in the second guide rail. The crossbar is located above the circuit board bracket, and the two ends of the crossbar are respectively detachably mounted on the first slider and the second slider. The buzzer is mounted on one side of the circuit board bracket. According to thedetection fixture for the wire foot, the length of the wire foot is detected by the laser, the detection precision is high, the false positive rate is low, and the device can be prevented from beingdamaged by using a plastic measuring piece to detect the position where the wire is too long.

Description

technical field [0001] The invention relates to a jig for detecting stitches. Background technique [0002] Electronic devices are generally installed on printed circuit boards by means of solder paste operations. Finger plugs are one of the commonly used electronic devices in electronic equipment, but the lengths of electronic pins are inconsistent when they leave the factory. Generally, the factory will first cut the wire pins to an appropriate length at the processing station, and then dip the wire pins of the electronic device with tin through a wave soldering furnace after the board is inserted, so that the electronic device will be fixed. But after that, the quality of the solder and other hidden dangers that may cause quality problems will be checked. Among them, the length of the wires under the circuit board is one of the items that must be inspected. Generally, the wires under the board should not exceed 2.5mm. At present, the factory is the most The commonly used...

But after that, the quality of the solder and other hidden dangers that may cause quality problems will be checked. Among them, the length of the wires under the circuit board is one of the items that must be inspected. Generally, the wires under the board should not exceed 2.5mm. At present, the factory is the most The commonly used method is to measure directly through the fixture, which not only wastes time, but also easily leads to damage to the device during the detection process, and even leads to the scrapping of the product. Therefore, there is an urgent need for a method that can realize automatic detection and ensure that the device will not be damaged Damaged line pin detection jig
