Description

Technical Field

[0001] This utility model relates to the technical field of capacitance testing equipment, specifically an automatic sorting and testing machine for stacked capacitors. Background Technology

[0002] The automatic sorting and testing machine for multilayer capacitors is an automated device used in the field of electronic component manufacturing to perform performance testing and screening of multilayer capacitors.

[0003] Currently, most multilayer capacitor sorting and testing machines on the market use a method of sequentially positioning and testing single or a small number of capacitors when performing positioning tests on multilayer capacitors. This method suffers from low positioning efficiency and long testing cycles, making it difficult to meet the needs of large-scale production. Although some equipment has attempted to test multiple groups of capacitors simultaneously, due to unreasonable positioning structure design, the capacitors are prone to positional shifts during the testing process, affecting the accuracy and stability of the test results. Therefore, this utility model proposes an automatic multilayer capacitor sorting and testing machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic sorting and testing machine for multilayer capacitors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic sorting and testing machine for stacked capacitors, including a machine base, a chassis on the machine base, and an auxiliary positioning component on the chassis;

[0006] The auxiliary positioning component includes a tooling base plate mounted on the chassis. Several sets of test limiting cavities are formed on both sides of the tooling base plate. A rectangular groove is provided in the middle of the horizontal direction of the tooling base plate. A guide rod is provided in the rectangular groove. A notch is provided at the end of the test limiting cavity at both ends of the tooling base plate near the guide rod.

[0007] The auxiliary positioning component also includes a stop plate, the protruding end of which is connected to the guide rod, and the stop plate is located within the test limiting cavity. The guide rod is connected to the output end of the telescopic cylinder on the side wall of the tooling base plate.

[0008] The machine is also equipped with a testing instrument, which is connected to a testing pin via a transmission line.

[0009] Preferably, the guide rod has slots on both ends, and the abutments in the test limiting cavities at both ends are sequentially engaged in the slots on both ends of the guide rod through the protruding ends on the end sides.

[0010] Preferably, the lower end of the tooling base plate is provided with a positioning plate, and the tooling base plate is mounted on the chassis through the positioning plate.

[0011] Preferably, the machine base is equipped with a rotary motor, which is connected to the upper chassis.

[0012] Preferably, the output end of the rotary motor is provided with transmission teeth, and the lower end of the chassis is provided with a tooth cavity, wherein the tooth cavity at the lower end of the chassis engages with the transmission teeth at the output end of the rotary motor.

[0013] Preferably, the testing instrument is mounted on the machine base via extension brackets at both ends. The testing instrument is divided into several groups of testing units, and each group of testing units is electrically connected to a test pin.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By setting multiple test limiting cavities on both sides of the tooling base plate and combining the telescopic cylinder to drive the guide rod to drive the plate, multiple stacked capacitors can be quickly and accurately positioned at the same time, greatly improving the positioning efficiency. Compared with the traditional method of positioning single capacitors in sequence, the number of capacitors that can be positioned and tested per unit time can be increased several times, effectively meeting the high-efficiency testing needs of large-scale production.

[0016] (2) The structure of the abutment plate and the guide rod connected by the slot ensures the stability and consistency of the abutment plate positioning action, so that the stacked capacitors in each test limiting cavity can be reliably pressed and fixed. At the same time, the group detection unit design of the test instrument, together with multiple test limiting cavities, can realize the synchronous detection of capacitors at different positions, ensure the accuracy of the test data of each capacitor, avoid test errors caused by unstable capacitor positioning or asynchronous detection, and improve the reliability of product testing.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: an automatic sorting and testing machine for multilayer capacitors, including a machine base 1, a chassis 2 on the machine base 1, and an auxiliary positioning component on the chassis 2. The auxiliary positioning component includes a tooling base plate 4 mounted on the chassis 2. Several sets of test limiting cavities 41 are formed on both sides of the tooling base plate 4. A rectangular groove 42 is provided in the middle of the horizontal direction of the tooling base plate 4, and a guide rod 43 is provided within the rectangular groove 42. Notches 421 are provided at the ends of the test limiting cavities 41 near the guide rods 43 at both ends of the tooling base plate 4. The auxiliary positioning component also includes a stop plate 44, the protruding end of which is connected to the guide rod 43 and abuts against it. Plate 44 is located inside test limiting cavity 41, and guide rod 43 is connected to the output end of telescopic cylinder 45 on the side wall of tooling base plate 4; the machine base 1 is also equipped with test instrument 6, which is connected to test pin 62 through transmission line. By setting multiple sets of test limiting cavities 41 on both sides of tooling base plate 4, and combining telescopic cylinder 45 to drive guide rod 43 to drive plate 44, multiple sets of stacked capacitors can be quickly and accurately positioned at the same time, which greatly improves positioning efficiency. Compared with the traditional method of positioning single capacitors sequentially, the number of capacitors that can be positioned and tested per unit time can be increased several times, effectively meeting the high-efficiency testing needs of large-scale production.

[0024] Please see Figures 1 to 4 The guide rod 43 has slots 431 on both ends. The abutment plate 44 in the test limiting cavity 41 at both ends is sequentially engaged in the slots 431 on both ends of the guide rod 43 through the protruding end on the end side. Through the engaging structure, when the equipment is maintained or the abutment plate 44 is replaced, it is only necessary to pull the protruding end of the abutment plate 44 out of the slot 431 to easily remove the abutment plate 44 for repair or replacement. Then, the new abutment plate 44 is accurately engaged in the slot 431. No complicated installation tools and operating procedures are required, which improves the maintenance efficiency of the equipment.

[0025] Please see Figures 1 to 4 The tooling base plate 4 is provided with a positioning plate 411 at its lower end, and the tooling base plate 4 is mounted on the chassis 2 through the positioning plate 411.

[0026] Please see Figures 1 to 4The machine base 1 is equipped with a rotary motor 3, which is connected to the upper chassis 2. The output end of the rotary motor 3 is equipped with a transmission gear 31, and the lower end of the chassis 2 is equipped with a toothed cavity 21. The toothed cavity 21 at the lower end of the chassis 2 engages with the transmission gear 31 at the output end of the rotary motor 3. Through the cooperation between the rotary motor 3 and the transmission gear 31, the rotation angle and position of the chassis 2 can be precisely controlled, ensuring that the test limiting cavity 41 on the tooling base plate 4 can be accurately aligned with the test pins 62 and other components of the test instrument 6, thus ensuring the positional accuracy of the multilayer capacitor during the test process and improving the accuracy and reliability of the test results.

[0027] Please see Figures 1 to 4 The testing instrument 6 is mounted on the machine base 1 via extension brackets 5 at both ends. The testing instrument 6 is divided into several groups of testing units 61. Each group of testing units 61 is electrically connected to the test pins 62. This ensures that each stacked capacitor has an independent and stable circuit connection during the test, avoiding interference and errors that may occur due to multiple capacitors sharing the same testing circuit, thereby ensuring the accuracy and stability of the test results.

[0028] In use, the stacked capacitors to be tested are placed one by one into the test limiting cavities 41 on both sides of the fixture base plate 4. The stacked capacitors are inserted along the notches 421 of the test limiting cavities 41 to initially fix their positions. Then, the telescopic cylinder 45 is activated. The output end of the telescopic cylinder 45 pushes the guide rod 43 to move within the rectangular groove 42. Since the protruding end of the abutment plate 44 engages with the slots 431 on both ends of the guide rod 43, the guide rod 43 drives the abutment plate 44 to move synchronously within the test limiting cavities 41, pressing the stacked capacitors together and completing precise positioning. After positioning is completed, the rotary motor 3 is started. The transmission gear 31 at its output end meshes with the tooth cavity 21 at the lower end of the chassis 2, driving the chassis 2... The rotating mechanism transports the tooling base plate 4 mounted on the chassis 2 and the pre-positioned multilayer capacitor to the corresponding position below the testing instrument 6. Several sets of detection units 61 of the testing instrument 6 are electrically connected to the test pins 62 via transmission lines. When the multilayer capacitor rotates to the corresponding position with the chassis 2, the test pins 62 descend and contact the electrodes of the multilayer capacitor. Each detection unit 61 detects the capacitance, loss tangent, insulation resistance, and other performance parameters of the multilayer capacitor, and transmits the collected data to the testing instrument 6 for analysis and processing. The testing instrument 6 judges the test data according to the preset performance indicators and classifies the multilayer capacitor into qualified and unqualified products.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
