Problems solved by technology

In the test process of the automatic test equipment, the measurement circuit is measured by the contact of the movable conductive brush. Due to the unreliable factors such as large contact resistance in the movable contact, there are inevitably problems such as wrong measurement and missing measurement, resulting in the failure of good products. The existence of a serious quality accident hidden danger that is absolutely not allowed to occur is mixed with defective products
In addition, although these two test methods can also meet the production requirements, they can only distinguish whether the product is qualified or not. For products of the same specification, the quality grade cannot be distinguished, which makes it impossible for the manufacturer to conduct differentiated sales according to the quality of the product.

Embodiment Construction

[0020] Such as figure 1 As shown, the multi-stage classification test process of the automatic aging machine includes the following steps:

[0021] (1) A tester 6 for measuring the parameters of the capacitor 12 is placed at the test station, and eight sets of measuring probes 7 are installed on the measurement channel of the tester 6. The data communication port of the tester 6 is connected to a PLC control terminal 8, which is controlled by the PLC The terminal 8 sets the required test parameters for the tester 6, and the test parameters are the capacity of the capacitor 12, the loss tangent value, the leakage current value or the equivalent series impedance value;

[0022] (2) The rack 1 carrying the capacitor 12 is sent into the aging constant temperature furnace 2, and after the aging is finished, it is released from the furnace and enters the cooling station 3. After being cooled by the strong wind blown by the fan, the rack 1 is transferred to the charging station 4, an...

Abstract

The invention discloses a multi-segment graded testing technology for a full-automatic aging machine, and the technology employs a multi-segment measurement mode for multiple measurement of the electrical performance parameters of each capacitor, can achieve the flexible setting of quality grading standards according to the mean value of the measurement data of a database while judging whether each capacitor is qualified and avoiding quality accidents, and effectively improves the testing efficiency of the capacitors.

Description

technical field [0001] The invention belongs to the technical field of capacitor detection, and in particular relates to a multi-stage classification test process for a full-automatic aging machine. Background technique [0002] Aluminum electrolytic capacitor is a passive electronic component, which plays the role of coupling, filtering and energy storage in the circuit, so it is widely used in various electronic products. Generally speaking, the leakage current value (LC), equivalent series resistance value (ESR) and loss tangent value (tgδ) of the capacitor are as small as possible within the standard; in terms of product quality, the capacity parameter (C) Within the standard, the smaller the LC, tgδ, and ESR, the higher the reliability and durability (life) of the capacitor, that is, the higher the quality level of the capacitor, in other words, the higher the selling price. Bring higher economic benefits. [0003] The traditional capacitor production process usually ...
