Description

Technical Field

[0001] The utility model belongs to the technical field of capacitance detection, and in particular relates to a device for detecting defective electrolytic capacitors. Background Art

[0002] An electrolytic capacitor is a polarized capacitor consisting of a metal foil (usually aluminum or tantalum) as the positive electrode, a metal oxide film (such as aluminum oxide or tantalum pentoxide) in close contact with the positive electrode as the dielectric, and a cathode composed of a conductive material, an electrolyte (which can be liquid or solid), and other materials. Electrolytic capacitors are named because the electrolyte is located at the cathode, and the positive and negative poles must not be connected incorrectly during use. Electrolytic capacitors have a large capacitance, but they also have high leakage and poor stability, making them suitable for power supply filtering or low-frequency circuits.

[0003] The prior art discloses a device for detecting defective electrolytic capacitors with patent announcement number CN219162185U. The above patent uses a blocking half-ring to block and support the electrolytic capacitor when in use, thereby facilitating automatic support detection of the electrolytic capacitor to be detected, making the detection steps simpler and more convenient, and the detected data more accurate, thereby improving the automation effect of the automatic detection device for electrolytic capacitors, eliminating manual clamping, and improving detection efficiency. However, the following deficiencies still exist in actual use: From a practical point of view, each time the detection device detects a single electrolytic capacitor, it needs to go through the steps of placement, fixation, detection, screening or removal in sequence. The operation is relatively cumbersome, and the detection cannot be performed automatically, which affects the detection efficiency.

[0004] Therefore, a device for detecting defective electrolytic capacitors is needed to solve the problem in the prior art that when detecting a single electrolytic capacitor, the operation is relatively cumbersome and the detection cannot be performed automatically, which affects the detection efficiency.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] See also Figure 1-4 The utility model provides a defective electrolytic capacitor detection device, including a box body 1, a placement mechanism 2, a detection head 3, a good product drop-out port 4, a defective product drop-out port 5 and a storage mechanism 6. The placement mechanism 2 is arranged inside and above the box body 1, the detection head 3 is arranged above the placement mechanism 2, the good product drop-out port 4 and the defective product drop-out port 5 are respectively opened on the top plate of the box body 1, and the storage mechanism 6 is respectively arranged below the good product drop-out port 4 and the defective product drop-out port 5.

[0024] The placement mechanism 2 consists of a motor 201, a gear assembly 202, a connecting shaft 203, a rotating disk 204, an electric push rod 207 and a fixed block 208.

The connecting shaft 203 is fixedly connected to the top of the driven gear, and the rotating disk 204 is fixedly connected to the outside of the connecting shaft 203.

[0025] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that a placement slot 205 is symmetrically opened on the rotating disk 204, a mounting cavity 206 is symmetrically opened in the middle of the placement slot 205, an electric push rod 207 is fixedly connected to the side of the mounting cavity 206 away from the placement slot 205, and a fixed block 208 is fixedly connected to the extended end of the electric push rod 207.

[0026] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that the top surface of the fixing block 208 is provided with an inclined surface, and the end of the fixing block 208 away from the electric push rod 207 is provided with an arc groove;

[0027] By providing the inclined surface and the arc-shaped groove, electrolytic capacitors of different sizes can be better clamped, thereby improving the clamping stability and the scope of application.

[0028] According to the above working process, it can be seen that: through the placement mechanism 2, not only can electrolytic capacitors of different sizes be clamped, thereby improving the stability and applicability of the clamping, but the screening of electrolytic capacitors can also be automatically completed. During the detection, the staff can place new electrolytic capacitors in the empty placement slot 205 without delaying the detection speed, thereby improving the detection rate.

[0029] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth noting that the storage mechanism 6 is composed of a fixed ring 601, a storage bucket 602, a slide 603, a buffer layer 604, a fixed seat 605, a slide bar 606, a slider 607, a spring 608, a connecting block 609 and a connecting rod 610. The fixed ring 601 is fixedly connected to the interior of the box body 1, the storage bucket 602 is slidably connected to the interior of the fixed ring 601 via the slide 603, and the buffer layer 604 is fixedly installed inside the storage bucket 602;

[0030] By sliding the storage bucket 602 inside the fixing ring 601 , the stability of the up and down movement of the storage bucket 602 can be ensured, which facilitates the collection of electrolytic capacitors.

[0031] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth mentioning that the fixed seat 605 is symmetrically fixedly connected to the top of the bottom plate of the box body 1, the slide bar 606 is fixedly connected between the two fixed seats 605, the slider 607 is symmetrically slidably connected to the outside of the slider 606, the spring 608 is fixedly connected between the slider 607 and the fixed seat 605, and is sleeved on the outside of the slider 606, the upper and lower ends of the connecting rod 610 are respectively rotatably connected to the connecting blocks 609, the lower connecting block 609 is fixedly connected to the top of the slider 607, and the upper connecting block 609 is fixedly connected to the bottom surface of the storage bucket 602.

[0032] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth noting that the motor 201 and the electric push rod 207 are electrically connected to the controller respectively, the size of the good product drop-out port 4 and the defective product drop-out port 5 are larger than the placement slot 205, and the storage bucket 602 is respectively provided directly below the good product drop-out port 4 and the defective product drop-out port 5;

[0033] If the test is qualified, the controller is notified to control the electric push rod 207 outside the electrolytic capacitor, so that the fixed block 208 releases the clamping of the electrolytic capacitor, allowing it to fall into the storage bucket 602 below through the good product drop-out port 4; if it is unqualified, it continues to rotate with the rotating disk 204, and after rotating 90 degrees, controls the electric push rod 207 outside the electrolytic capacitor to make it fall into the storage bucket 602 below through the defective product drop-out port 5, thereby completing the screening of the electrolytic capacitor.

[0034] This solution has the following working process: when in use, the electrolytic capacitor is placed inside the placement slot 205, and then the electric push rod 207 automatically controls the fixed block 208 to approach the outer wall of the electrolytic capacitor to clamp it to ensure the stability of the electrolytic capacitor when the rotating disk 204 rotates, and the connecting shaft 203 is driven to rotate by the motor 201 below, and the internal electrolytic capacitor is driven to rotate by the rotating disk 204. When it rotates to the bottom of the detection head 3, it is tested. If the test is qualified, the controller is notified to control the electric push rod 207 outside the electrolytic capacitor to make the fixed block 208 release the clamping of the electrolytic capacitor, so that it falls into the storage bucket 602 below through the good product drop-out port 4; if it is unqualified, it continues to rotate with the rotating disk 204, and after rotating 90 degrees, the electric push rod 207 outside the electrolytic capacitor is controlled to pass The defective products fall through the drop-out port 5 into the storage bucket 602 below, completing the screening of the electrolytic capacitors. During the inspection, the staff can place new electrolytic capacitors in the vacant placement slots 205 without delaying the inspection speed, thereby improving the inspection rate. When there are no electrolytic capacitors in the storage bucket 602, the elastic action of the spring 608 drives the top surface of the storage bucket 602 to be close to the bottom surface of the top plate of the box body 1, thereby preventing the electrolytic capacitors from being subjected to a large impact force when falling and causing damage to them. Moreover, as the number of internal electrolytic capacitors increases, gravity drives the storage bucket 602 to move downward, and drives the connecting blocks 609 to slide toward each other through the connecting rod 610, thereby stretching the spring 608. As the electrolytic capacitors in the storage bucket 602 gradually accumulate, the height of the electrolytic capacitors does not increase when they fall, thereby improving the safety of the storage mechanism 6.

[0035] In summary: through the placement mechanism 2, not only can electrolytic capacitors of different sizes be clamped, improving the stability and applicability of the clamping, but also the screening of electrolytic capacitors can be automatically completed. During the detection, the staff can place new electrolytic capacitors in the vacant placement slots 205 without delaying the detection speed, thereby improving the detection rate; through the storage mechanism 6, when there is no electrolytic capacitor inside the storage bucket 602, the elastic action of the spring 608 drives the top surface of the storage bucket 602 to be close to the bottom surface of the top plate of the box body 1, avoiding the electrolytic capacitor from being subjected to a large impact force when it falls and causing damage to it, and as the number of internal electrolytic capacitors increases, gravity drives the storage bucket 602 to move downward, but the electrolytic capacitors inside the storage bucket 602 gradually accumulate, and the height of the electrolytic capacitor does not increase when it falls, thereby improving the safety of the storage mechanism 6.
