Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a capacitor terminal cover plate detection device. Background Art

[0002] The capacitor terminal cover (or terminal cover) is an important part of the capacitor assembly, usually used to protect and fix the capacitor terminals, which are the external connection parts of the capacitor used to make electrical connections with the circuit. The capacitor terminals transfer the charge of the capacitor through their interface with the circuit board or other electronic components. The design and type of the terminals can vary depending on the application and specifications of the capacitor.

[0003] Before the capacitor terminal cover is used, if the terminals are uneven, it will cause difficulties in installing the components on the circuit board and difficult to insert or weld correctly. Therefore, after the capacitor terminal cover is produced, inspection personnel are required to check whether the two terminal bases are of the same height. When using the existing inspection device, it is necessary to manually use a height gauge to check whether the two terminal bases are of the same height one by one.

If the position of the capacitor terminal cover is not aligned, the position of the connecting plate is not reset and is still at the bottom. The connecting plate will resist the trapezoidal block during movement, driving the trapezoidal block to move closer to the cylinder, so that the trapezoidal block drives the square rod to insert into the inside of the bayonet. At this time, the cylinder will not move down, avoiding the height detection of the subsequent threaded terminal base being affected by the wrong position of the capacitor terminal cover.

[0021] The downward movement of the telescopic end of the cylinder 9 drives the T-plate 10 downward, so that the T-plate 10 drives the detection sleeve 25 downward, and the downward movement of the detection sleeve 25 drives the detection column 26 downward. When the detection column 26 moves downward, it will be inserted into the threaded holes of the two threaded terminal bases. If the position of the threaded terminal base is tilted or offset, the detection column 26 cannot be correctly inserted into the inside of the threaded hole.

When the scale displays data beyond the range value, the operator can judge that the capacitor terminal cover 2 is unqualified. When the device is used to detect the two threaded terminal bases on the capacitor terminal cover 2, there is no need to manually use a height gauge to detect them one by one. During batch detection, the detection efficiency is greatly improved and the production efficiency of the capacitor terminal cover 2 is accelerated.

At this time, the cylinder 9 will not move downward, avoiding the height detection of the subsequent threaded terminal base being affected by the wrong position of the capacitor terminal cover 2.

[0027] It should be noted that when the present invention is in use, the operator manually presses the capacitor terminal cover plate 2 to be tested into the inside of the circular groove 4 away from the cylinder 9, so that the bottom of the capacitor terminal cover plate 2 is flush with the upper surface of the circular groove 4. Since the rubber roller 6 abuts against the outer surface of the capacitor terminal cover plate 2, the capacitor terminal cover plate 2 will stop inside the circular groove 4. When the capacitor terminal cover plate 2 is pressed, the positioning pin 7 is driven to move downward, so that the positioning pin 7 drives the connecting plate 17 to move downward, and through the downward movement of the connecting plate 17, the connecting plate 17 drives the sliding sleeve 19 to move downward, and through the downward movement of the sliding sleeve 19, the chamfer of the bottom end thereof is abutted against the bevel 20, and through the directional rotation of the servo motor, the turntable 11 is driven to rotate, so that the turntable 11 drives the driving gear 13 to move, and the driving gear 1 3 drives itself to rotate by meshing with the annular gear 12, and the driving gear 13 drives the sliding sleeve 19 to rotate by the friction force generated by the chamfer and the bevel 20, and the sliding sleeve 19 drives the rotating shaft 18 to rotate through the protrusion and the sliding groove 35, and the rotating shaft 18 drives one of the rubber rollers 6 to rotate, so that the rubber roller 6 drives the capacitor terminal cover plate 2 to rotate, and when the bleed hole 3 on the capacitor terminal cover plate 2 rotates to the position of the positioning pin 7, the positioning pin 7 will slide into the inside of the bleed hole 3 through the force of the fourth spring 37, at this time, the connecting plate 17 resets the sliding sleeve 19 and separates from the driving gear 13, and the capacitor terminal cover plate 2 stops rotating.
