Description

technical field [0001] The invention relates to the field of patch equipment, in particular to an automatic patch capacitor integrated machine. Background technique [0002] In the process of capacitor production, it is necessary to paste the capacitors on the paper tape according to the uniform direction of positive and negative poles for discharging. The scattered capacitors are neatly pasted on the paper tape, which can facilitate the control of the number of capacitors and facilitate the batching of capacitors. For external transportation and sales, the capacitors are pasted on the paper tape in an orderly manner according to the uniform positive and negative pole directions, which is also convenient for consumers to distinguish the positive and negative poles of the capacitor, and saves the time consumers need to judge the positive and negative poles of the capacitor.

Problems solved by technology

[0003] However, the volume of general electrolytic capacitors is small, and the way to judge electrolytic capacitors is not only to look at the label on the top of the capacitor, but also to judge the positive and negative poles of the capacitor by the length of the pins, or by measuring the resistance of the capacitor with a multimeter, but in In large-scale mass production, the above method of judging the positive and negative poles of capacitors requires a lot of labor and is inefficient. The error rate will increase when the staff work for a long time, resulting in low production quality.

There are types of chip capacitors in electrolytic capacitors. Since chip capacitors need to be attached to the circuit board, the pins of general chip capacitors are very short. Therefore, in the production process of chip capacitors , manually judging the positive and negative conditions of chip capacitors becomes an infeasible method

[0004] However, there are a large number of capacitor processing equipment in the prior art. For example, the utility model patent "SMD Aluminum Electrolytic Capacitor Base Automatic Detection Device" with the publication number CN201711294U discloses the use of a CCD camera to detect unqualified capacitors. And use the rejecting device to remove unqualified products. This utility model simply judges whether the capacitor meets the quality index through the appearance of the capacitor and whether the capacitor is good or bad. This method has high inaccuracy. Capacitors that cannot be charged and discharged normally are detected, and the quality of the capacitor cannot be truly detected

However, the capacitor processing equipment in the prior art only processes part of capacitor production, and there are few integrated machines that can complete the processing of chip capacitors, resulting in a low degree of automation in production and processing, and the production efficiency cannot be improved.
