Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an ageing equipment of MLCC product high temperature interchange, which comprises an outer shell 1, the front of shell 1 is provided with door plant 2, door plant 2 is connected with shell 1 through the hinge, one side of door plant 2 is provided with fixed plate 3, the top of fixed plate 3 openly is provided with host computer interface 4, the inside of shell 1 is provided with internal system 5, the surface of door plant 2 is provided with recess 6, door plant 2 contacts with fixed plate 3, open door plant 2, make 1 inside the shell show out, host computer interface 4's bottom is provided with sweeps a yard rifle 7, scan the product, internal system 5 includes control module, a capacitor, relay and power, internal system 5 is connected with host computer interface 4, can operate internal system 5 through host computer interface 4.

Referring to fig. 1-2, an alarm lamp 8 is disposed at the top of the housing 1 to provide an audible and visual alarm to remind the operator to perform the treatment.

When the device works, an operator uses a code scanning gun 7 provided by the device to scan DM codes on an electrode plate on a clamp to input computer information, and selects a pre-input aging condition on an upper computer interface 4; operating an upper computer interface 4 to enable the system to be in an aging state, controlling an aging power supply and a temperature controller to start working by the system, wherein J1 (an aging cut-in/charging relay) is at a tangential normally-on point, and J2 (an aging cut-in relay after charging) is still at a normally-off point; the element to be aged is charged by R1 (charging resistor); when a certain aged element is broken down (or the leakage current is greater than the set upper limit), the drive control module detects a short-circuit signal, when the short-circuit time lasts for more than 1 second, current inquiry is carried out, a station with the leakage current greater than the set leakage current number is judged to be a capacitor short circuit, the system disconnects J1 (an aged cut-in/charging relay), an aging loop is not electrified any more, meanwhile, a software interface is distinguished by obvious colors to prompt which specific capacitor in the aging board is short-circuited (or overrun), an audible and visual alarm is realized through an alarm lamp 8 at the top to prompt a worker to carry out treatment, the system is restored to an aged electrifying state after the treatment is finished, and the process is repeated when the next capacitor is broken down; after the aging is quitted or the aging time is up, the system automatically discharges, a J4 (aging/discharging switching relay) is tangent to a normally open point, a discharging loop is connected, a capacitor discharges through a resistor R3 (discharging resistor), when the voltage on the capacitor is smaller than 10V or a set value, the discharging is finished, the system gives a discharging completion indication, equipment can record in-out box data, test condition information and test engineering abnormal information through configured hardware such as a code scanning gun 7 and the like, and can upload the in-out box data, the test condition information and the test engineering abnormal information to an MES database for flow management and control.
