Description

Technical Field

[0001] The present invention relates to the technical field of capacitor preparation, and in particular to a fully automatic capacitor integrated detection system suitable for performance detection of axial metal film capacitors. Background Art

[0002] Axial metal film capacitors are capacitors whose two-pole leads are on the same axis. They are generally non-inductive structures, wound with metallized polyester film as the dielectric / electrode, and the conductors are made of tinned copper-clad steel wire (or soft wire), wrapped with polyester tape on the outside, and sealed with epoxy resin at both ends. Axial capacitors have the following characteristics: non-inductive structure, suitable for high current applications; low high-frequency loss: suitable for high-frequency, DC, AC and pulse circuits; high insulation resistance: good self-healing properties and long life. Axial capacitors are widely used in various electronic and electrical equipment, including audio-visual equipment, power supply equipment, post and telecommunications, data processing, etc. Especially in audio equipment, axial film capacitors can provide stable electrical performance, effectively reduce noise interference, and improve sound quality.

[0003] Performance testing of axial metal film capacitors is generally carried out on semi-finished products (the capacitor core is wound into a cylindrical shape, wrapped with polyester tape, sprayed with a metal layer at both ends, and no leads are installed). Performance testing cannot be performed on finished products after the leads and casing are installed, and the capacitor core cannot be tested using existing fully automatic capacitor testing systems.

[0004] Currently, the testing method for axial metal film capacitors is that the operator tests the capacitor cores one by one using a test meter. The operator connects the capacitor core to the corresponding performance test meter through two wires, and then energizes the capacitor core to test the performance of the capacitor core using the rated voltage or current. The performance test of axial metal film capacitors includes three performance tests: withstand voltage, insulation, and capacity. It requires three manual testing processes, which results in a heavy workload for operators, low testing efficiency, and the risk of electric shock. Summary of the Invention

[0008] During operation, the three finger cylinders are started synchronously, driving the three pairs of electrode mounting plates to move inward at the same time, so that the N groups of probes on the electrode mounting plates are simultaneously clamped on the two end faces of the corresponding capacitor core. The capacitor core on the first testing station from the left in the withstand voltage testing area, insulation testing area and capacity testing area can be subjected to withstand voltage testing, insulation testing and capacity testing respectively at the same time.

The N capacitor cores whose voltage resistance performance has been tested are synchronously transported to the right to the N corresponding detection stations in the insulation detection area. The N capacitor cores whose insulation performance has been tested are synchronously transported to the right to the N corresponding detection stations in the capacity detection area. The optocoupler sensor sensing turntable rotates through N gaps, indicating that N capacitor cores to be tested have been transported to the right. The PLC controller issues a control instruction after receiving N sensing signals from the optocoupler sensor according to the program settings to control the feeding synchronous belt. The step belt stops running, and the finger cylinders on the three electrode assemblies are controlled to start synchronously, driving all probes to synchronously hold the two end faces of the capacitor core on the corresponding inspection station, and synchronously start the voltage gauge, insulation gauge and relay corresponding to the first capacitor core from the left in each inspection area, so that the three inspection areas start the corresponding performance inspection synchronously.

The first bending edge is fixedly connected to the inner bottom surface of the material receiving transition plate, so that the third bending edge and the fourth bending edge form a suspended receiving V-shaped groove 2221 with the opening facing upward, and the third bending edge and the fourth bending edge are symmetrical on the left and right. An avoidance opening groove is provided in the middle of the right side of the receiving plate to facilitate the lifting movement of the lifting V-shaped plate. The avoidance opening groove divides the receiving V-shaped groove on the right side of the receiving plate into front and rear V-shaped grooves, which can just receive the two ends of the capacitor core coming down from the lifting V-shaped plate.

[0015] The V-shaped groove is a suspension structure with a certain elasticity, which can play a certain shock-absorbing role on the capacitor core 9.

[0016] As a further improvement of this technology, it also includes an audible and visual alarm. When a defective capacitor core appears during the inspection process, the PLC controller will control the audible and visual alarm to emit an audible and visual alarm, prompting the operator to remove the defective capacitor core from the defective workstation in time.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention integrates withstand voltage testing, absolute testing and capacity testing from left to right on the same platform and performs them synchronously. A PLC controller is used to control the handling device for automatic feeding, automatic testing and automatic discharging, which greatly improves the testing efficiency and reduces the labor intensity of the operator. Only one operator is required for one device, which greatly reduces labor costs. 2. The present invention adopts an optical coupling sensor to enable the feeding synchronous belt to automatically convey the N capacitor cores to be tested required for one clamping to the right. After the PLC controller receives the N sensing signals sent by the optical coupling sensor, it automatically stops the conveyance of the capacitor cores and simultaneously starts the performance testing of the withstand voltage testing area, the insulation testing area, and the capacity testing area. The PLC controller collects the test data of the same batch of capacitor cores and displays it on the touch screen. When a defective capacitor core appears, the position and defective test data of the defective capacitor core will be displayed on the touch screen and marked as a defective product. The PLC controller will control the defective product to no longer undergo the corresponding performance test in the subsequent testing area and issue an alarm to prompt the operator to remove the defective product from the defective product station in time. 3. The present invention uses a finger cylinder to control the probes on the two electrode mounting plates to clamp and hold them on both ends of the capacitor core to be measured. There is no need to manually connect the power supply, which effectively eliminates the risk of electric shock. BRIEF DESCRIPTION OF THE DRAWINGS

An optical coupling sensor 206 is provided above the turntable 205 for sensing the notches 2051 on the turntable 205.

An avoidance opening groove is provided in the middle of the right side of the receiving plate 222 to facilitate the lifting and lowering movement of the lifting V-shaped plate 219.
