Description

Technical Field

[0001] The invention relates to the technical field of capacitor production, and in particular to a high-precision automatic detection device for the electrical performance of a capacitor. Background Art

[0002] A capacitor is an electronic component that can store electric charge. It is widely used in electronic circuits and is mainly composed of two conductive electrodes and an insulating medium in between. The electrodes are usually made of metal materials, such as aluminum, tantalum, etc.; the insulating medium can be a variety of materials such as ceramics, mica, polyester film, electrolytic paper, electrolyte, etc. For example, the medium of a ceramic capacitor is a ceramic material that separates the two metal electrodes; an electrolytic capacitor uses an electrolyte as a medium, one of the electrodes is a metal foil, and the other electrode forms an oxide film in the electrolyte through electrolysis.

[0003] Capacitors need to be inspected one by one after production. The main inspection items include whether the pins are intact in appearance, the capacitance deviation in performance, and the withstand voltage performance. At the same time, capacitors that fail the inspection must be classified for centralized processing. In the prior art, traditional inspection equipment usually moves the capacitors through a conveyor belt, and then uses a cylinder to push the capacitors to different segmented areas. The unqualified capacitors slide out along the inclined discharge chute. However, during the sliding process, the capacitor is not stable enough due to the inclined surface and is prone to tipping over. The tipped capacitor may collide with the previous capacitor, causing the pins to bend or be damaged, further affecting its performance and the accuracy of the test results.

[0004] In addition, the capacitors need to be highly aligned with the front end of the feeding trough during the sorting process. However, after long-term use of the equipment, the conveyor belt is prone to friction or looseness, resulting in a height difference with the track. This phenomenon not only affects the smoothness of the sorting work, but also increases the risk of capacitor tipping. Especially for capacitors with longer pins or lighter weight, the probability of tipping is higher, which directly affects the reliability and efficiency of the sorting process. Summary of the invention

The height of the end of the bottom of the feed trough away from the conveyor belt gradually decreases, and the end of the feed trough is flush with the upper surface of the conveyor belt. An isolation box is also provided between two adjacent feed troughs, and a capacitor anti-dumping structure is installed inside the isolation box. Local height adjustment mechanisms are evenly installed inside the groove, and the local height adjustment mechanism is placed between the upper and lower layers of the conveyor belt.

[0009] Furthermore, the outer surface of the belt is equally divided into three connection blocks, the outer surface of the connection block is provided with a mounting groove, and a tilting rod is hinged inside the mounting groove.

[0010] Furthermore, one of the tilting rods passes through the through slot, and the end of the tilting rod contacts the capacitor sliding in the feeding chute, a spring is welded inside the installation slot, and the other end of the spring is welded to the inner surface of the tilting rod.

[0011] Furthermore, columns are evenly and vertically arranged on both sides of the inner wall of the groove, and the local height adjustment mechanism corresponds one-to-one to the material discharge chute. The local height adjustment mechanism includes a double-threaded rod installed for horizontal rotation inside the groove, and a knob is arranged at the end of the double-threaded rod, and the knob is placed on the rear side of the outside of the working table.

[0012] Furthermore, moving blocks are symmetrically screwed on the surface of the double-threaded rod, and the two moving blocks are screwed on different threaded surfaces respectively, and a connecting rod is hinged on the top of the moving block.

[0013] Furthermore, a lifting plate is slidably installed between two corresponding columns, and the ends of the two connecting rods are hinged to the lower surface of the lifting plate.

[0014] Furthermore, vertical plates are symmetrically arranged on the upper surface of the lifting plate, and an auxiliary roller is rotatably installed between the two vertical plates, and the auxiliary roller is in contact with the lower surface of the upper layer of the conveyor belt.

[0015] The present invention provides a high-precision automatic detection device for the electrical performance of capacitors. It has the following beneficial effects: The present invention provides a high-precision automatic detection device for the electrical performance of capacitors. Through the linkage design of the performance detection mechanism and the sorting mechanism, the fully automated operation of the capacitor from appearance detection to performance detection and classification and sorting is realized. The performance detection mechanism includes a detection table, a visual detection camera, a flip cylinder and a performance detection seat. On the basis of ensuring that the pins of the capacitor are facing upward, the appearance defects of the capacitor can be accurately identified by taking images through the visual detection camera; after the appearance detection is completed, the flip cylinder accurately flips the capacitor and inserts it into the performance detection seat for electrical performance detection; this design avoids the instability of manual operation and greatly improves the efficiency and accuracy of detection.

The conveyor belt can smoothly transport the capacitors to different classification areas, and the push cylinder accurately pushes them into the corresponding unloading trough according to the capacitor test results; the unloading trough is designed as an inclined surface, so that the capacitors can slide down under the action of gravity. At the same time, the capacitor anti-dumping structure inside the isolation box effectively prevents the capacitors from tipping over during the sliding process, avoiding the increase in the defective rate due to pin damage; the overall optimization of the sorting structure improves the classification efficiency and the operating stability of the equipment.

[0017] The present invention also solves the problem of height difference between the conveyor belt and the feeding chute through a local height adjustment mechanism. The local height adjustment mechanism is composed of a double-threaded rod, a moving block, a lifting plate and an auxiliary roller. The double-threaded rod is rotated to drive the moving block to move relative to each other, thereby adjusting the height of the lifting plate and the auxiliary roller, thereby achieving fine adjustment of the local height of the conveyor belt; this design overcomes the height difference problem caused by loose conveyor belt, wear or long-term use, and ensures the smoothness and stability of capacitors during the classification process.

[0018] In addition, the capacitor anti-dumping structure set up in the isolation box, including components such as pulleys, belts, connecting blocks and lift rods, provides effective support for the capacitor through dynamic contact between the lift rod and the capacitor sliding path; when the capacitor slides out of the discharge chute, the lift rod will automatically retract and prepare for the next capacitor to slide; this structural design ensures the stability of the capacitor during the sorting process, prevents the occurrence of tipping, and at the same time protects the pins of the capacitor, improving the classification accuracy of the equipment and the product yield.

[0031] Example 2: See Figure 1-8 , a high-precision automatic detection device for capacitor electrical performance, including a performance detection mechanism 1 and a sorting mechanism 2. Specifically, this embodiment verifies the effect of the device on capacitor appearance detection and performance classification in detail through experiments.

[0032] In the experiment, five different types of capacitors were selected for testing, namely C1 (aluminum electrolytic capacitor, capacitance 220μF), C2 (ceramic capacitor, capacitance 100pF), C3 (polyester film capacitor, capacitance 1μF), C4 (tantalum capacitor, capacitance 47μF), C5 (mica capacitor, capacitance 10nF). Ten samples of each type were used, a total of 50 capacitors, and the following performance indicators were tested in the experiment: 1. Appearance pin integrity inspection: The capacitor pins were photographed by the visual inspection camera 14 to check the integrity and non-bending of the pins. The results showed that the pin inspection results of all capacitor samples were qualified, and the pin damage rate was 0%. The imaging accuracy of the visual inspection camera 14 reached 0.01mm, which can identify the slight deformation of the pins, ensuring the accuracy of the appearance inspection of the capacitors.

[0033] 2. Electrical performance test: The capacitor is inserted into the performance test seat 15 by turning the cylinder 13 to perform electrical performance test. During the test, the electrical performance of each capacitor, such as capacity, resistance, and withstand voltage, is measured. The experimental data show:

[0034] It can be seen from the test results that the device of the present invention can accurately detect the electrical performance of different types of capacitors. In particular, in the withstand voltage test, each capacitor is gradually boosted until it reaches The whole process is automatically controlled until the rated voltage is reached, ensuring the safety and accuracy of the withstand voltage test.

[0035] Example 3: In this example, the capacitor classification process was tested in depth. The sorting mechanism 2 includes a conveyor belt 24, a push cylinder 25, a feed chute 27 and an extended sorting table 22. In order to verify its reliability in the automated classification process, we selected five groups of capacitor samples of different weights and sizes for the experiment: 1. Capacitor samples and classification results: Sample A: weight 0.5g, size 6×6mm Sample B: weight 1.2g, size 10×10mm Sample C: weight 0.8g, size 8×8mm Sample D: weight 2.0g, size 12×12mm Sample E: weight 1.0g, size 9×9mm During the experiment, the cylinder 25 pushes the capacitor into the corresponding feed trough 27 according to the detection result of the capacitor. In order to verify the classification accuracy of the equipment, we calculated the classification success rate and the capacitor dumping rate. The experimental data shows:

[0036] It can be seen from the experimental data that the classification success rate is above 97% and the dumping rate is low, especially for The samples A and E, which are lighter in weight, did not tip over at all, which fully demonstrated the reliability of the present invention in gravity sliding and sorting.

[0037] Example 4: This example tests the accuracy and adaptability of the local height adjustment mechanism 3 of the conveyor belt 24 in detail. Five groups of different height deviations are used to verify the performance of the adjustment mechanism: 1. Initial height deviation and adjustment results:

[0038] In the experiment, by rotating the knob 32, the double-threaded rod 31 drives the moving block 33 to adjust the height of the lifting plate 35 to eliminate the height difference between the conveyor belt 24 and the unloading chute 27. The results show that the adjustment mechanism can effectively eliminate more than 90% of the initial height deviation and ensure the stability of the capacitor classification process.

[0039] Embodiment 5: In this embodiment, an experiment was conducted to verify the function of the capacitor anti-dumping structure 4 inside the isolation box 28. Five groups of capacitors with different materials, sizes and weights were selected for the sliding test to observe their stability during the sliding process.

[0040] 1. Slip test data:

[0041] Experiments show that the anti-dumping structure 4 inside the isolation box 28, through the tilting rod 45, contacts the sliding path of the capacitor, and can effectively prevent the capacitor from tipping over during the sliding process in the feed chute 27. In particular, for capacitors with light weight and high diameter ratio, the stability of their sliding is significantly improved.

[0042] Working principle: The capacitor to be tested is placed on the upper surface of the test table 12 by a mechanical arm or a supporting cylinder, and its pins are ensured to face upwards. Then, the pins are photographed by a visual inspection camera 14 for visual inspection, and the photographs are transmitted to a computer for analysis. Then, the capacitor is removed and turned over by a flip cylinder 13, and then inserted into a performance inspection seat 15. The electrical performance is tested by powering on, and then the capacitor is transferred to another platform by a feeding cylinder 16. Then, the capacitor is turned over by another flip cylinder 13 and placed on the upper surface of a conveyor belt 24. The capacitor can be transported by the conveyor belt 24. At this time, the computer will send the classification result information to the pushing cylinder 25. The multiple pushing cylinders 25 correspond to the problems such as poor appearance, large capacity, unstable capacity, excessive loss tangent, low insulation resistance, and insufficient withstand voltage. When the corresponding capacitor moves to the corresponding pushing cylinder 25 position, the pushing cylinder 25 can push the capacitor to the corresponding feed trough 27. The lower surface of the feed trough 27 is an inclined surface. At this time, the capacitor will automatically slide downward to realize the sorting work.

[0043] When the sorted capacitor is pushed into the discharge chute 27, during the backward sliding process, one of the three tilting rods 45 will exceed the through slot 210 and be placed at one end thereof close to the conveyor belt 24. At this time, the capacitor can be supported and limited to prevent the capacitor from tipping over due to the inclined surface of the discharge chute 27. Under the action of gravity, the downward movement of the capacitor will drive the belt 42 to rotate. When the capacitor is about to slide out of the discharge chute 27, the matching tilting rod 45 will be squeezed into the installation slot 44 by the tail of the through slot 210 and completely enter the isolation box 28. At this time, another connecting block 43 is placed at the end, and the tilting rod 45 on its surface pops up to prepare for the next capacitor to slide in. The overall length of the belt 42 must ensure that the three equally divided connecting blocks 43 are working. When one is finished working, the other just slides out. The internal spring 46 can be squeezed at the tail and keep the power stored. When it returns to the end of the through slot 210, the tilting rod 45 will be popped out again, thereby realizing the cycle work to prevent the capacitor from tipping over and causing damage to the electrode pin.

[0044] When pushing the capacitor by pushing the cylinder 25, it is necessary to ensure that the conveyor belt 24 is flush with the front end surface of the discharge chute 27. However, during use, there is a height difference due to friction, loose belts, and deformation of the capacitor under pressure. At this time, the height of the corresponding discharge chute 27 can be fine-tuned. By rotating the knob 32 on the outside, the double-threaded rod 31 can be driven to rotate, and then the two moving blocks 33 can be driven to move closer to or away from each other. The lifting plate 35 is limited by the columns 231 on both sides and can only slide in the vertical direction. At this time, the height of the lifting plate 35 can be adjusted by the cooperation of the moving block 33 and the connecting rod 34, and then the supporting force of the auxiliary roller 37 on the conveyor belt 24 can be adjusted to achieve fine-tuning of the height of the conveyor belt 24 area to ensure smoothness when pushing the capacitor classification.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
