Description

Technical Field

[0001] This utility model relates to the technical field of capacitor quality testing equipment, and in particular to a quality testing equipment for capacitor production. Background Technology

[0002] A capacitor is an electronic component that can store and release electrical charge. It is usually fixed to the capacitor body by soldering. After the capacitor is manufactured, quality inspection equipment is needed to test the connection strength between the leads and the capacitor body to evaluate whether the capacitor meets the design requirements.

[0003] However, most of the existing quality testing equipment for capacitor production on the market is not convenient for workers to align the capacitor leads with the fixtures of the testing equipment, requiring workers to make multiple adjustments, which increases the complexity of operation. In addition, most of the existing quality testing equipment for capacitor production on the market is not convenient for workers to classify and collect the tested capacitors into qualified and unqualified categories, which is not conducive to the later recycling and processing of unqualified products.

[0004] Therefore, those skilled in the art provide a quality inspection device for capacitor production to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a quality inspection device for capacitor production. The device adjusts the height of the base plate by means of an adjusting threaded rod in the positioning mechanism, and guides the pins with the pin slots on the support frame, making it easy for the pins and clamps to align. The first servo motor in the separating mechanism drives the first threaded rod to change the position of the separating block in the feed inlet, and the electric telescopic rod drives the push block to facilitate sorting and collection.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quality inspection device for capacitor production includes a collection box, a separating mechanism, a lifting mechanism, and a positioning mechanism. The collection box has a separating mechanism inside, which includes two fixed blocks. A feed inlet is provided in the middle of the upper end of the collection box. The upper ends of the inner walls on both sides of the collection box are fixedly connected to the fixed blocks. A moving groove is provided on one side of the fixed blocks near the center of the collection box. A first servo motor is provided on the inner wall of the front end of one moving groove. A first threaded rod is fixedly connected to the output shaft of the first servo motor. A separating block is threadedly connected to the outer wall of the first threaded rod. A support block is fixedly connected to the middle of the rear end of the upper end of the collection box.

[0008] An electric telescopic rod is fixedly connected to the upper end of the support block, and a push block is fixedly connected to the output shaft of the electric telescopic rod. A lifting mechanism is provided on the other side of the upper end of the collection box. The lifting mechanism includes a column, and a lifting groove is opened at the upper end of the outer wall of one side of the column. A second servo motor is provided on the bottom surface inside the lifting groove. A second threaded rod is fixedly connected to the output shaft of the second servo motor. A lifting block is threadedly connected to the outer wall of the second threaded rod. A positioning mechanism is provided in the middle of the upper end of the collection box. The positioning mechanism includes a support frame and a clamping seat.

[0009] Through the above technical solution, the first servo motor in the separating mechanism drives the first threaded rod to rotate, causing the separating block threadedly connected to the first threaded rod to move along the moving groove, changing the position of the separating block in the feed inlet on the collection box. In conjunction with the electric telescopic rod, the push block pushes the tested capacitor out of the support frame, thus making it easier for staff to classify and collect the tested capacitors according to whether they are qualified or unqualified.

[0010] Furthermore, the lower end of the support frame is fixedly connected to the collection box, a pin slot is provided in the middle of the upper part of the outer wall of the front end of the support frame, an adjusting threaded rod is rotatably connected to the middle of the rear end of the upper end of the support frame, the lower end of the adjusting threaded rod passes through the support frame and is threadedly connected to the bottom plate, a sliding groove is provided at the lower end of the clamping seat, a protective shell is fixedly connected to the outer wall of one side of the clamping seat, a third servo motor is provided on the bottom surface inside the protective shell, the output shaft of the third servo motor passes through the protective shell and is fixedly connected to a bidirectional threaded rod, and clamping blocks are threadedly connected to both sides of the outer wall of the bidirectional threaded rod.

[0011] With the above technical solution, the base plate is adjusted to a height that allows the capacitor to be placed in advance by adjusting the threaded rod in the positioning mechanism. When the operator places the capacitor on the base plate, the two leads of the capacitor are guided into the two clamping blocks by the lead slots opened on the support frame, which makes it easier for the operator to align the capacitor leads with the clamps of the testing equipment.

[0012] Furthermore, the front and rear ends of the outer wall of one side of the collection box are hinged to a box door, and a PLC control panel is fixedly connected to the upper end of the middle of the outer wall of one side of the collection box.

[0013] The above technical solution allows workers to remove capacitors from the two storage spaces inside the collection box via two hinged doors, while the PLC control panel enables workers to easily control the operation of the equipment.

[0014] Furthermore, the rear end of the first threaded rod is rotatably connected to the inner wall of the rear end of the movable groove, and the outer walls on both sides of the partition block are slidably connected to the movable groove.

[0015] Through the above technical solution, the first servo motor drives the first threaded rod to rotate inside the moving groove, so that the separator block threadedly connected to the first threaded rod can move along the moving groove in the feed inlet. When the separator block is located at the front end of the feed inlet, the capacitor falling from the support frame will fall into the unqualified product collection chamber at the rear end of the collection box, and when the separator block is located at the rear end of the feed inlet, the capacitor falling from the support frame will fall into the qualified product collection chamber at the front end of the collection box.

[0016] Furthermore, the upper end of the second threaded rod is rotatably connected to the top surface inside the lifting groove, and the lifting block slides inside the lifting groove;

[0017] The above technical solution involves using a second servo motor to drive a second threaded rod to rotate, causing a lifting block that is threadedly connected to the second threaded rod to move along a lifting groove.

[0018] Furthermore, a tension sensor is fixedly connected to one side of the lower end of the lifting block, and the upper end of the clamping seat is fixedly connected to the tension sensor;

[0019] The above technical solution involves moving the lifting block upwards to a pre-set distance, pulling the pins on the capacitor, using a tension sensor to detect changes in tension, and analyzing the pin's firmness by analyzing the changes in the tension curve.

[0020] Furthermore, the adjusting threaded rod is located inside the push block, and the base plate slides inside the support frame;

[0021] By placing the adjusting threaded rod inside the push block, the push block can avoid direct contact between the adjusting threaded rod and the capacitor. Instead, the adjusting threaded rod is threadedly connected to the base plate, allowing the base plate to change its height within the support frame. This ensures that most of the capacitor's leads extend out of the lead slots on the support frame, making it easier for them to be clamped by the clamping blocks.

[0022] Furthermore, the other side of the bidirectional threaded rod passes through the clamping seat and is rotatably connected to the inner wall of the other side of the slide groove, and the clamping blocks slide inside the slide groove;

[0023] The above technical solution uses a third servo motor to drive a bidirectional threaded rod to rotate inside a slide groove, causing a clamping block threaded to the bidirectional threaded rod to move within the slide groove. By reducing the distance between the two clamping blocks, the two leads of the capacitor are clamped together, facilitating tensile testing.

[0024] This utility model has the following beneficial effects:

[0025] 1. The present invention proposes a quality inspection device for capacitor production. The base plate is pre-adjusted to a height that allows the capacitor to be placed by adjusting the threaded rod in the positioning mechanism. When the operator places the capacitor on the base plate, the two leads of the capacitor are guided into the two clamping blocks by the lead slots opened on the support frame. This makes it easier for the operator to align the capacitor leads with the clamps of the inspection device, thus reducing the complexity of operation.

[0026] 2. The present invention proposes a quality inspection device for capacitor production. The first servo motor in the separation mechanism drives the first threaded rod to rotate, causing the separation block threadedly connected to the first threaded rod to move along the moving groove, changing the position of the separation block in the feed inlet on the collection box. With the help of the electric telescopic rod, the push block pushes the inspected capacitors out of the support frame, which makes it easier for the staff to classify and collect the inspected capacitors into qualified and unqualified categories, and facilitates the subsequent recycling and processing of unqualified products.

The collection box 1 is provided with a separating mechanism 5, which includes two fixed blocks 502. A feed inlet 501 is provided in the middle of the upper end of the collection box 1. The upper ends of the inner walls on both sides of the collection box 1 are fixedly connected to the fixed blocks 502.

[0039] The front and rear ends of one side outer wall of the collection box 1 are hinged to doors 2. A PLC control panel 3 is fixedly connected to the upper part of the middle of one side outer wall of the collection box 1. Through the two hinged doors 2 on the collection box 1, operators can remove the capacitors from the two storage spaces inside the collection box 1. The PLC control panel 3 allows operators to easily control the operation of the equipment. The rear end of the first threaded rod 505 is rotatably connected to the inner wall of the rear end of the moving groove 503. The outer walls on both sides of the separator block 506 are slidably connected to the moving groove 503. The first servo motor 504 drives the first threaded rod 505 to rotate inside the moving groove 503, allowing the separator block 506, threadedly connected to the first threaded rod 505, to move along the moving groove 503 in the feed inlet 501. When the separator block 506 is at the front end of the feed inlet 501, the capacitors falling from the support frame 701 will fall into the feed inlet. The unqualified product collection chamber at the rear end of the collection box 1, and when the separator block 506 is located at the rear end of the feed inlet 501, the capacitor falling from the support frame 701 will fall into the qualified product collection chamber at the front end of the collection box 1. The upper end of the second threaded rod 604 is rotatably connected to the top surface inside the lifting groove 602. The lifting block 605 slides inside the lifting groove 602. The second servo motor 603 drives the second threaded rod 604 to rotate, so that the lifting block 605 threadedly connected to the second threaded rod 604 moves along the lifting groove 602. A tension sensor 606 is fixedly connected to one side of the lower end of the lifting block 605. The upper end of the clamping seat 706 is fixedly connected to the tension sensor 606. By moving the lifting block 605 upward to a predetermined distance, the pin on the capacitor is pulled. The tension sensor 606 detects the change in tension and analyzes the firmness of the pin by the change in the tension curve.

[0040] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The lower end of the support frame 701 is fixedly connected to the collection box 1. A pin groove 702 is provided in the middle of the upper part of the outer wall of the front end of the support frame 701. An adjusting threaded rod 703 is rotatably connected to the middle of the rear end of the upper end of the support frame 701. The lower end of the adjusting threaded rod 703 passes through the support frame 701 and is threadedly connected to the base plate 705. A sliding groove 704 is provided in the lower end of the clamping seat 706. A protective shell 707 is fixedly connected to the outer wall of one side of the clamping seat 706. A third servo motor 708 is provided on the bottom surface inside the protective shell 707. The output shaft of the third servo motor 708 passes through the protective shell 707 and is fixedly connected to a bidirectional threaded rod 709. Clamping blocks 710 are threadedly connected to both sides of the outer wall of the bidirectional threaded rod 709.

[0041] The adjusting threaded rod 703 is located inside the push block 508, and the base plate 705 slides inside the support frame 701. By placing the adjusting threaded rod 703 inside the push block 508, the push block 508 can avoid direct contact between the adjusting threaded rod 703 and the capacitor. The adjusting threaded rod 703 is threadedly connected to the base plate 705, allowing the base plate 705 to change its height within the support frame 701. This ensures that most of the capacitor's leads extend out of the lead slots 702 on the support frame 701, making it easier for the clamping blocks 710 to hold them. The other side of the bidirectional threaded rod 709 passes through the clamping seat 706 and is rotatably connected to the inner wall of the other side of the slide groove 704. The clamping blocks 710 slide inside the slide groove 704. The bidirectional threaded rod 709 is driven to rotate inside the slide groove 704 by the third servo motor 708, causing the clamping blocks 710 threadedly connected to the bidirectional threaded rod 709 to move within the slide groove 704. By reducing the distance between the two clamping blocks 710, the two leads of the capacitor are clamped, facilitating tensile force testing.

[0042] Working Principle: When using this quality inspection equipment for capacitor production, the operator first adjusts the threaded rod 703 to change the height of the base plate 705 within the support frame 701 to match the height of the capacitor. Then, the capacitor to be inspected is placed on the base plate 705. The lead slots 702 on the support frame 701 guide the capacitor leads into the space between the two clamping blocks 710. The PLC control panel 3 then activates the third servo motor 708, which rotates the bidirectional threaded rod 709, causing the clamping blocks 710 to clamp the leads. Next, the operator activates the second servo motor 603 via the PLC control panel 3, which rotates the second threaded rod 604, causing the lifting block 605 to move to the set position. Combined with the constraint of the support frame 701, the leads are then inspected. Strength testing utilizes a tension sensor 606 to detect changes in tension, reflecting whether the capacitor pins are within acceptable limits. Then, the third servo motor 708 is activated via the PLC control panel 3, causing the clamping block 710 to release the pins. Finally, the operator activates the first servo motor 504 via the PLC control panel 3 to drive the first threaded rod 505 to rotate, changing the position of the separator block 506 within the feed inlet 501. This, combined with the electric telescopic rod 507, pushes the capacitor out using the push block 508. When the separator block 506 is at the front end of the feed inlet 501, the capacitor falls into the collection chamber at the rear end of the collection box 1; when it is at the rear end, the capacitor falls into the collection chamber at the front end of the collection box 1, thus classifying and collecting the capacitors as qualified or unqualified.
