Description

Technical Field

[0001] This utility model relates to the field of capacitance detection technology, and more specifically, to a capacitance testing device. Background Technology

[0002] After manufacturing, capacitors need to undergo various performance tests, such as appearance testing, capacitance value testing, withstand voltage testing, maximum leakage current testing, loss angle testing, capacitance value error testing, temperature coefficient testing, failure rate testing, and operating temperature range testing, etc.

[0003] Current automatic capacitor testing machines typically use a sorting machine to select and position capacitors, clamping them onto a conveyor belt before sequentially transporting them to the testing device for testing. Alternatively, capacitors are inserted into a rack, connected to the rack via wires. As the rack is conveyed, leads on it contact the testing device to perform testing, after which the capacitors are collected by a receiving device. However, this structure cannot separate good and defective capacitors after testing, requiring manual sorting, which is time-consuming, labor-intensive, and impacts capacitor testing efficiency.

[0022] Example 1 Reference Figures 1-4 This embodiment provides a capacitance testing device, including a chassis 1. The chassis 1 is provided with a feeding mechanism 2, an incoming material detection mechanism 3, a pressure detection mechanism 4, a discharging mechanism 5, and a conveying track 6 passing through the incoming material detection mechanism 3 and the pressure detection mechanism 4. The entrance of the conveying track 6 is located at the outlet of the feeding mechanism 2, and the outlet of the conveying track 6 is located at the inlet of the discharging mechanism 5. The discharging mechanism 5 includes a mounting base 51. The end of the mounting base 51 near the pressure detection mechanism 4 is provided with a sliding seat 52, and the end of the mounting base 51 away from the pressure detection mechanism 4 is provided with multiple discharging channels 54. The top of the sliding seat 52 is provided with a carrying plate 53, and the carrying plate 53 is provided with a pin 58.

[0023] The sliding seat 52, the carrier plate 53, the ejector pin 58, and the unloading channel 54 work together to allow good and defective products to be unloaded separately, realizing the separation of good and defective products after capacitor testing. This simple and convenient operation improves capacitor testing efficiency. Furthermore, the loading mechanism 2, the incoming material inspection mechanism 3, the pressure detection mechanism 4, and the unloading mechanism 5 work together to achieve mechanized operation of capacitor loading, feeding, testing, and sorting. Compared to traditional capacitor testing which requires multiple devices, this device integrates multiple capacitor processing techniques into one unit, resulting in a high degree of integration, compact structure, and small footprint. It also reduces manual labor, lowers production costs, improves capacitor processing efficiency, and enhances economic benefits. A PLC control system is installed inside the chassis 1, electrically connected to each mechanism to control its operation. The conveyor track 6 is inclined, and baffles can be installed on both sides of the conveyor track 6.

[0024] In a preferred embodiment, the feeding mechanism 2 includes a vibrating feeder 21, and a material tray 22 is provided at the outlet of the vibrating feeder 21. The outlet of the material tray 22 is connected to the inlet of the conveying track 6.

[0025] In a preferred embodiment, the chassis 1 has a base plate 23, and the top of the base plate 23 has a hollow turntable 24. The turntable 24 has internal gear teeth, and the bottom of the material tray 22 has a gear 25 that meshes with the gear teeth. The turntable 24 has an annular groove at its top, and the inner side of the annular groove has annularly distributed gear teeth. The turntable 24 is driven by a servo motor. The servo motor drives the turntable 24 to rotate, and the gear 25, in turn, drives the material tray 22 to rotate, thereby allowing the capacitors to be sequentially transported from the outlet of the material tray 22 to the conveyor track 6.

[0026] In a preferred embodiment, the incoming material detection mechanism 3 includes a detection seat 31 mounted above the conveyor track 6, and an incoming material detector is provided at the bottom of the detection seat 31. The incoming material detector can be a photoelectric sensor, a capacitive proximity switch, or a laser displacement sensor.

[0027] In a preferred embodiment, the pressure detection mechanism 4 includes a high-voltage test column 41, a guide column 42 and a cylinder 43 are provided between the high-voltage test column 41 and the chassis 1, and multiple sets of probes 45 are provided at the bottom of the high-voltage test column 41, the probes 45 being used to electrically connect to capacitor pins.

[0028] In a preferred embodiment, the pressure detection mechanism 4 further includes two fixed seats 44 mounted above the conveyor track 6, with the two fixed seats 44 located at opposite ends of the high-voltage test column 41. A lifting column is movably connected to the top of each fixed seat 44. The high-voltage test column 41 is electrically connected to the control system and can measure multiple capacitors simultaneously, such as 16 or 30. The fixed seats 44 have a portal frame structure, and a cylinder is installed inside each fixed seat 44 to drive the lifting column to rise or fall.

[0029] In a preferred embodiment, the mounting base 51 has a guide rail 55 inside, and the sliding base 52 is slidably connected to the guide rail 55. The sliding base 52 is driven by a servo motor, which is electrically connected to the control system.

[0030] In a preferred embodiment, the feeding channel 54 is equipped with an optical fiber sensor, and a receiving box is provided at the outlet of the feeding channel 54. The receiving box includes a good product box 56 and a defective product box 57. There are three feeding channels 54, with good product boxes 56 corresponding to the two side feeding channels 54 respectively, and the defective product box 57 located between the two good product boxes 56. The optical fiber sensor detects changes in light signals (such as intensity, phase, wavelength, polarization state, etc.) and infers the measured parameters (such as temperature, pressure, displacement, vibration, etc.). The optical fiber sensor is used to detect capacitor drop and is electrically connected to the control system. When the high-voltage test column 41 detects that the nth capacitor is defective, and the optical fiber sensor detects that the (n-1)th capacitor has been fed into the good product box 56, it feeds back the signal to the control system. The control system then controls the servo motor to start, and the servo motor drives the sliding seat 52 to move, positioning the sliding seat 52 at the feeding channel 54 of the defective product box 57, so that the nth capacitor on the carrier plate 53 enters the defective product box 57 through the feeding channel 54. By using two good product boxes (56) in combination, materials can be collected continuously without stopping the machine.

[0031] The working principle of a capacitor testing device is as follows: a vibrating feeder 21 feeds capacitors into a holding tray 22. The holding tray 22 rotates, allowing the capacitors to be transported sequentially from the outlet of the holding tray 22 to the conveyor track 6. The material travels along the conveyor track 6 to the detection seat 31. The incoming material detector at the bottom of the detection seat 31 detects whether the capacitor is full. Subsequently, the capacitor enters below the high-voltage test column 41. The high-voltage test column 41 descends, causing the probe 45 to descend, so that the probe 45 is electrically connected to the capacitor pins. The high-voltage test column 41 releases high voltage to test the capacitor and transmits the test results to the control system.

[0032] After testing, the capacitors are transported to the carrier plate 53. The control system controls the servo motor to start, and the servo motor drives the sliding seat 52 to move along the guide rail, so that the carrier plate 53 is connected to different feeding channels 54 respectively, thereby feeding good products into the good product box 56 and defective products into the defective product box 57, realizing the separation of good and defective products.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
