Description

Technical Field

[0001] The utility model relates to the technical field of electronic component detection, in particular to a micro-crack detection device for an electrolytic capacitor plug-in pad. Background Art

[0002] An electrolytic capacitor is a type of capacitor. The metal foil is the positive electrode, and the oxide film in close contact with the positive electrode is the dielectric. The cathode is composed of conductive materials, electrolytes and other materials. The electrolyte is the main part of the cathode, hence the name electrolytic capacitor. Electrolytic capacitor plug-ins are often welded and installed on pads.

[0003] After the production of electrolytic capacitor plug-in pads, it is often necessary to use testing equipment to detect the surface quality of the pads. Microcracks that are invisible to the human eye often appear on the pads. It is necessary to use a detection device to magnify and detect products with larger microcrack areas, so that they can be discarded to ensure the quality of the pad products.

[0004] Among them, the utility model with authorization announcement number CN 109916345 A discloses a pad detection device. Although the machine-driven laser rangefinder solves the problem of avoiding false detection, wrong detection and missed detection in traditional manual visual inspection, effectively improving the detection efficiency and reducing labor costs, the machine moves the laser rangefinder slowly. If it is used for batch detection of electrolytic capacitor plug-in pads, the speed is too slow, resulting in low work efficiency. Utility Model Content

[0023] Among them, a cavity 31 is opened in the slider 3, and the slider 3 is mounted on the sliding seat 2. Rollers 32 are symmetrically arranged in the cavity 31 of the slider 3 for front and back rotation. The rollers 32 are arranged in the slide groove 21 to roll, and the bottom of the rollers 32 contacts the bottom wall of the slide groove 21. Through the rolling of the four rollers 32 on the slide groove 21, the slider 3 can be supported on the sliding seat 2 while being able to slide back and forth.

[0024] In addition, a placement groove 42 is opened inside the upper frame body of the placement rack 4, and rubber pads 43 are attached to the side walls around the placement groove 42. An opening 41 is opened at the front end of the upper frame body of the placement rack 4. The rubber pad 43 facilitates the placement of the soldering pad to make it more firmly installed, and the opening 41 at the front end facilitates the operator to buckle out and remove the soldering pad more easily.

[0025] Moreover, a threaded portion 71 is provided in the middle portion of the rod body of the driving rod 7, and a fixing seat 8 is movably provided on the threaded portion 71. Connecting portions 72 are provided on both sides of the rod body of the driving rod 7 and connected to the threaded portion 71. The cylindrical diameter of the connecting portion 72 is larger than the outer diameter of the thread of the threaded portion 71. The left connecting portion 72 of the driving rod 7 is rotatably mounted on the left bearing seat 5, and the right connecting portion 72 of the driving rod 7 is rotatably mounted on the right bearing seat 6 and connected to the crank 11 on the right side of the right bearing seat 6. The crank 11 can be shaken through the left bearing seat 5 and the right bearing seat 6 to drive the driving rod 7 to rotate.

[0026] At the same time, the fixed seat 8 includes a fixed plate 83, on which the detection device 10 is fixedly installed on the horizontal plate in front of the fixed plate 83, a threaded tube 81 is fixedly connected to the upper back side of the rear plate of the fixed plate 83, and a sliding tube 82 is fixedly connected to the lower back side of the rear plate of the fixed plate 83 and located on the threaded tube 81, and a threaded hole engaged with the threaded portion 71 of the driving rod 7 is provided on the threaded tube 81, and the threaded tube 81 is engaged with the threaded portion 71 of the driving rod 7, and the sliding tube 82 is arranged on the sliding rod 9 to slide, and the threaded tube 81 of the fixed seat 8 is engaged with the threaded portion 71 of the driving rod 7, and cooperates with the restriction of the sliding tube 81 at the bottom, so that the fixed seat 8 can move left and right with the rotation of the driving rod 7.

[0027] In this embodiment, when it is necessary to detect micro cracks on the surface of the electrolytic capacitor plug-in pad, the present detection equipment can be used. First, the electrolytic capacitor plug-in pad is horizontally installed on the placement rack 4, and the electrolytic capacitor plug-in pad is fixed in the placement groove 42 of the placement rack 4. The rubber pad 43 can fit tightly against the side of the electrolytic capacitor plug-in pad to ensure that it is fixed more firmly to prevent the electrolytic capacitor plug-in pad from shaking, and the opening 41 at the front end makes it easier for the operator to buckle out and remove the pad.

[0029] When lateral movement is required, adjustment can be made by shaking the crank 11. The crank 11 is rotated clockwise so that the drive rod 7 connected thereto can rotate with the left bearing seat 5 and the right bearing seat 6, so that the threaded tube 81 mounted on the threaded portion 71 and meshing therewith rotates accordingly. With the restriction of the sliding tube 82 below being sleeved on the sliding rod 9, the threaded tube 81 can only move to the right, thereby adjusting the detection device 10 to the right.

[0030] At the same time, when the detection device 10 needs to move to the left, it is only necessary to rotate the shaking handle 11 counterclockwise, and the moving speed of the detection device 10 can be determined by the shaking speed.

[0031] In the utility model, the placement rack 4 is set up to effectively fix the electrolytic capacitor plug-in pad and facilitate quick removal. By setting the slider 3, the detection device 10 can be moved in the front and rear directions by manual pushing. The driving rod 7 is driven to rotate by shaking the crank 11 to move the detection device 10 in the left and right directions, and the moving speed of the detection device 10 can be determined by the shaking speed. In this way, the detection device 10 can be quickly moved above the electrolytic capacitor plug-in pad that needs to be detected, so as to detect microcracks. The cost is relatively lower than that of the equipment for mechanically automating the movement of the detection device 10, and the speed is faster, which can improve the detection work efficiency and is suitable for batch detection of electrolytic capacitor plug-in pads.
