Abstract
Description
Technical Field
[0001] This application relates to the field of industrial testing technology, and in particular to a CCD testing instrument for shaded-pole motors. Background Technology
[0002] Shaded-pole motors, as an important type of single-phase asynchronous motor, are widely used in home appliances, ventilation equipment, and other fields. Their unique stator short-circuit ring and main winding structure place extremely high demands on manufacturing precision. Traditional testing methods have many limitations; the inspection of shaded-pole motors largely relies on manual visual inspection and mechanical measuring tools. Manual inspection is easily affected by subjective factors, resulting in poor consistency and difficulty in detecting microscopic defects. With the development of industrial automation, CCD inspection technology, with its advantages in automation, has been widely used in industrial inspection. Developing a CCD inspection instrument for shaded-pole motors to achieve accurate inspection has become a key issue that the industry urgently needs to address.
[0003] The existing technology still has the following problems:
[0004] 1. When existing CCD inspection instruments inspect workpieces, the workpiece slips on the conveyor belt due to inertia when the inspection stops, resulting in inaccurate positioning of the workpiece. At the same time, the weight of the product and supporting structure causes the workpiece to sink on the conveyor belt, which can also cause the position of the workpiece to deviate. This leads to excessive measurement errors in the inspection dimensions, missed or misjudged defects, and shape matching failures that result in the rejection of qualified products. Consequently, qualified products are treated as defective products, wasting production resources. In addition, it is difficult to detect inaccurate workpiece positioning in a timely manner, which can lead to a large number of defective products flowing into subsequent processes or the market, exacerbating quality problems.
[0005] 2. Existing CCD inspection instruments are prone to damaging workpieces when rejecting defective products. When the inspection instrument detects defective products, it often uses a cylinder to push them away directly. However, the workpiece needs to be clamped during inspection, which can easily cause wear and tear on the clamps during pushing away and collisions with the equipment during subsequent collection, resulting in damage to the workpiece and increasing subsequent maintenance costs. Summary of the Invention

[0017] The technical solution provided in this application has at least the following technical effects or advantages:
[0018] 1. By employing support and positioning components, this method effectively solves the problems of existing CCD inspection instruments where, when the conveyor belt stops inspecting workpieces, the workpiece slips due to inertia, leading to inaccurate workpiece positioning. Additionally, the weight of the product and support structure causes the workpiece to sink on the conveyor belt, further deviating its position. This results in excessive measurement errors, missed or misjudged defects, and shape mismatch failures leading to the rejection of qualified products, wasting production resources. Furthermore, it is difficult to detect inaccurate workpiece positioning in a timely manner. This invention addresses the issue of a large number of defective products flowing into subsequent processes or the market, exacerbating quality problems. Through support and positioning components, the invention can reposition the workpiece when it shifts, correct its position, and ensure the accuracy of the workpiece's position. This prevents measurement errors from exceeding limits, avoiding missed or misjudged defects, and prevents shape matching failures that could lead to the rejection of qualified products. It also prevents qualified products from being mistaken for defective ones, saving production resources. Furthermore, it allows for timely detection when the workpiece's position is accurate, preventing a large number of defective products from flowing into subsequent processes or the market and improving the accuracy of the testing equipment.
[0019] 2. By employing a rejection assembly, this invention effectively solves the problem of existing CCD inspection instruments easily damaging workpieces when rejecting defective products. Currently, defective products are often directly pushed away by cylinders, but the workpiece needs to be clamped during inspection, which can easily cause wear and tear on the clamps during pushing and collisions with the equipment during subsequent collection, leading to workpiece damage and increased maintenance costs. This invention, through its rejection assembly, can eject the product from the clamps during rejection, preventing wear and tear on the clamps during pushing, reducing collisions with the equipment during collection, preventing workpiece damage, and lowering subsequent maintenance costs.

[0033] When the conveyor belt stops for inspection, the workpiece may slip on the conveyor belt due to inertial force, resulting in inaccurate positioning of the workpiece to be inspected. This invention uses a support component and a positioning component to locate the workpiece when it shifts position, and can correct the position of the shifted workpiece to ensure the accuracy of the workpiece's position and avoid exceeding the measurement error limit. Furthermore, when rejecting defective products, which can easily damage the workpiece, this invention uses a rejection component to push the product out of the clamp during rejection, preventing wear and tear on the clamp during pushing and reducing collisions with the equipment during collection.
[0034] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0035] Example 1:
[0036] Please see Figure 1 and Figure 2 As shown, a CCD inspection instrument for shaded-pole motors includes an inspection stage 1 and an inspection body 2. The inspection body 2 is fixedly mounted on the upper surface of the inspection stage 1. A CCD sensor is installed inside the inspection body 2. The CCD sensor is used to detect the quality of the shaded-pole motors and then reject unqualified shaded-pole motors. A rotating rod 3 is rotatably connected to the inner wall of the inspection stage 1. A conveyor belt 4 is sleeved on the outer surface of the rotating rod 3. There are two conveyor belts 4. A support assembly 5 is placed on the upper surface of the conveyor belts 4 and is located between the two conveyor belts 4. A positioning assembly 6 is installed on the inner wall of the inspection body 2. A rejection assembly 7 is installed on the outer surface of the inspection stage 1. A stepper motor is installed inside the inspection stage 1, and the output end of the stepper motor is sleeved with the rotating rod 3. A support plate is fixedly mounted on the inner wall of the inspection stage 1. The support plate is located directly below the positioning assembly 6 and the support plate... The upper surface and the lower surface of the conveyor belt 4 are attached. The conveyor belt 4 and the support plate are slidably connected. The support plate is used to provide rigid support for the support component 5 when it moves to the positioning component 6, which facilitates subsequent inspection. The support component 5 is clamped between the two conveyor belts 4. The support component 5 is supported and clamped by the conveyor belts 4, which improves the stability of the support component 5 on the conveyor belts 4. The operation of the stepper motor drives the rotating rod 3 to rotate. The rotation of the rotating rod 3 drives the conveyor belt 4 to transport the support component 5, which facilitates the inspection body 2 to inspect the support component 5. The positioning component 6 is used to reposition the support component 5 when it deviates, and at the same time, it issues an alarm to facilitate subsequent maintenance of the equipment. When it is necessary to reject defective products, the rejection component 7 rejects and collects the defective products, while qualified products are processed and used.
[0037] Please see Figure 3 and Figure 4As shown, the support assembly 5 includes a support base 51. Two first floating mechanisms 52 are symmetrically distributed about the middle of the support base 51. A connecting seat 53 is provided on the upper surface of the first floating mechanism 52. Positioning rods 54 are fixedly installed at both ends of the connecting seat 53. A second floating mechanism 55 is provided in the inner cavity of the connecting seat 53. Two alarm mechanisms 56 are symmetrically distributed on one side of the connecting seat 53. A lifting mechanism 57 is provided in the inner cavity of the second floating mechanism 55. A base 58 is fixedly installed at the bottom of the support base 51. The base 58 is located between two conveyor belts 4, and its outer surface is in close contact with one side of the conveyor belt 4. The lower surface of the support base 51 is in contact with the upper surface of the conveyor belt 4. Placing the support base 51 on the upper surface of the conveyor belt 4 allows the base 58 to be clamped between the two conveyor belts 4 for stable conveying. The first floating mechanism 52 is used to control the connection seat 53 within the support base 51. The cavity is flexibly connected, allowing the connecting seat 53 to be flexibly fixed in the inner cavity of the support seat 51. When the support seat 51 moves to the positioning component 6, the positioning rod 54 is used to check the height of the connecting seat 53 to prevent the height of the shaded pole motor to be tested on the second floating mechanism 55 from not meeting the requirements. When the height of the connecting seat 53 deviates, the first floating mechanism 52 can issue an alarm to facilitate equipment maintenance. The second floating mechanism 55 can be used to clamp and limit the workpiece to be tested. When the second floating mechanism 55 deviates on the upper surface of the conveyor belt 4, the alarm mechanism 56 can issue an alarm. At the same time, the positioning component 6 repositions the second floating mechanism 55 so that the workpiece can return to its original position to be tested when it deviates, enabling the workpiece to be tested accurately and preventing inaccurate test data due to positional deviation. The lifting mechanism 57 is used to lift the workpiece when rejecting unqualified products, so that the workpiece is removed from the clamping of the second floating mechanism 55, preventing direct pushing from damaging the product and increasing maintenance costs.
[0038] Please see Figures 4-9As shown, the first floating mechanism 52 includes a connecting frame 521. A first slide rod 522 is fixedly installed on the outer surface of the connecting frame 521. A first spring 523 is sleeved on the outer surface of the first slide rod 522. A connecting rod 524 is slidably connected to the inner cavity of the connecting frame 521.

A clamping block 557 is fixedly installed on one side of the middle portion of the adjusting block 555 towards the middle of the support platform 551. A positioning groove 558 is opened in the middle portion of the positioning block 554. Both sides of the positioning groove 558 are inclined surfaces. The second slide rods 552 and... The connecting seat 53 is slidably connected, and the third spring 553 is located between the support platform 551 and the inner wall of the connecting seat 53. There is a gap between the support platform 551 and the inner wall of the connecting seat 53. The alarm mechanism 56 includes a connecting plate 561, which is fixedly connected to the connecting seat 53. A second alarm 562 is fixedly installed on the upper surface of the connecting plate 561. A second button 563 is provided in the middle of the upper surface of the connecting plate 561.

Limiting rods 564 are fixedly installed at both ends of the connecting plate 561. A fourth spring 565 is sleeved on the outer surface of the limiting rod 564, and a protruding plate 566 is slidably connected to the outer surface of the limiting rod 564.The fourth spring 565 is located between the convex plate 566 and the connecting plate 561. The two ends of the convex plate 566 are flush and the middle is raised. The two ends of the convex plate 566 are inclined surfaces. A pressing rod 567 is fixedly installed on the lower surface of the convex plate 566. The pressing rod 567 is aligned with the second button 563. There is a gap between the pressing rod 567 and the second button 563. A pressure strip 568 is fixedly installed on the lower surface of the positioning block 554. A pressure cylinder 569 is rotatably connected to the bottom end of the pressure strip 568. The pressure cylinder 569 is located in the middle of the inclined surface of the convex plate 566, and the pressure cylinder 569 is in contact with the inclined surface of the convex plate 566. The convex plate 566 and the connecting seat 53 do not contact each other. The positioning component 6 includes a positioning frame 61. The positioning frame 61 is fixedly connected to the inner wall of the detection body 2. Positioning plates 62 are symmetrically distributed on the inner wall of positioning frame 61. The two ends of positioning plates 62 are inclined surfaces. The spacing between positioning plates 62 is equal to the diameter of positioning rod 54. When the support assembly 5 moves to the positioning assembly 6, the positioning rod 54 is located between two positioning plates 62. A fixing plate 63 is installed on the upper surface of positioning frame 61. A first cylinder 64 is provided on the top and bottom wall of the fixing plate 63. A first piston rod 65 is slidably connected to the inner cavity of the first cylinder 64. A fixing ring 66 is fixedly installed on the outer surface of the first piston rod 65. A positioning wheel 67 is provided at the bottom end of the first piston rod 65. A limiting plate 68 is fixedly installed on the outer surface of positioning frame 61. The limiting plate 68 is located below the fixing ring 66. When the support assembly 5 is directly below the positioning assembly 6, the fixing ring 66 is positioned below the bottom surface of the positioning frame 61. The upper surface of the positioning ring 67 and the positioning plate 68 are in contact, and the positioning wheel 67 and the positioning groove 558 coincide. The positioning plate 68 is used to limit the fixed ring 66 and fix the position of the positioning wheel 67 when it moves down, so as to prevent excessive pressure on the positioning block 554 and the positioning groove 558. There are two positioning components 6, both of which are located on the inner wall of the detection body 2 and are symmetrically distributed. When the shaded pole motor is detected, the workpiece to be detected is placed in the middle of the support table 551. By rotating the threaded rod 556, the adjusting block 555 is driven to slide on the upper surface of the support table 551, so that the clamping block 557 clamps and fixes the bottom of the workpiece, improving the stability of the workpiece on the support table 551. When the support seat 51 moves to the positioning frame 61, the positioning rod 54 The positioning rod 54 will pass between the two positioning plates 62. When the height of the support platform 551 does not meet the requirements, that is, when the height of the workpiece to be inspected deviates, the positioning plate 62 will exert a squeezing force on the first cylinder 64. At this time, the positioning rod 54 cannot pass between the two positioning plates 62, but will be squeezed against the inclined surface of the positioning plate 62. Since the support plate below the support assembly 5 is supported at this time, even if the support base 51 is subjected to downward squeezing force, it will not cause the conveyor belt 4 to dent downward and affect the overall height of the support assembly 5. In this way, the connecting seat 53 will squeeze the first floating mechanism 52, that is, the connecting seat 53 will drive the connecting frame 521 to move. At this time, the first sliding rod 522 slides on the inner wall of the support base 51 and slides on the inner wall of the limiting block 5210.The first spring 523 on one side is compressed, and the retaining ball 525 disengages from the recessed hole on the inner wall of the support base 51. This compression causes the connecting rod 524 to be housed within the inner cavity of the connecting frame 521, compressing the second spring 527. The housed connecting rod 524 causes the pressure block 526 to slide within the inner cavity of the connecting frame 521. The sliding of the pressure block 526 compresses the first button 528, causing the first alarm 529 to sound. Raising the height of the workpiece to be inspected does not meet requirements, necessitating equipment maintenance. Under the elastic force of the first spring 523, when the positioning rod 54 disengages from the positioning plates 62, the connecting frame 521 returns to its original position, and the retaining ball 525... The connector 53 engages with the recessed hole to stabilize the height of the connector 53 within the support 51. Under normal circumstances, the height of the connector 53 and the support 51 remain relatively stable, meaning the height of the workpiece to be tested is also relatively stable. Through the flexible limiting effect of the first floating mechanism 52, when the workpiece to be tested does not shift position, the positioning rod 54 passes precisely between the two positioning plates 62, without exerting any pressure on the positioning rod 54. This indicates that the height of the workpiece to be tested on the support 551 meets the testing requirements. When an interaction force is generated between the positioning rod 54 and the positioning plate 62, it indicates a problem with the height of the workpiece to be tested, requiring equipment maintenance. In a horizontal position, the conveyor belt 4 clamps and limits the base 58 to ensure the support 51... The stability of the lower surface and the upper surface of the conveyor belt 4 is improved, meaning that the position of the support seat 51 between the conveyor belts 4 will not be affected by the downward pressure of the positioning wheel 67 and the limiting position of the positioning plate 62. When the support seat 51 moves to the area to be inspected, the operation of the first cylinder 64 drives the first piston rod 65 to press down, so that the positioning wheel 67 and the positioning groove 558 are aligned. At this time, the position of the workpiece to be inspected is accurate and meets the inspection requirements. When the support seat 51 slips on the conveyor belt 4, or the position of the conveyor belt 4 deviates slightly, the downward pressure of the positioning wheel 67 will contact the inclined surfaces on both sides of the positioning groove 558. Under the pressure of the positioning wheel 67, the positioning block 554 will move. The movement of the positioning block 554 will drive the second slide rod 552 to slide in the inner cavity of the connecting seat 53, and the ball 525 and the concave... The force exerted by the hole and the elastic force of the first spring 523 prevent the positioning wheel 67 from pressing down and causing the connecting seat 53 to move downward within the cavity of the support seat 51. This means the support platform 551 slides horizontally within the cavity of the connecting seat 53, allowing for positional correction and improving workpiece inspection accuracy. Furthermore, when the support platform 551 shifts, the pressure bar 568 at the lower end of the positioning block 554 moves. This movement of the pressure bar 568 causes the pressure cylinder 569 to press against the inclined surface of the convex plate 566. At this time, the convex plate 566 moves towards the connecting plate 561, slides on the limiting rod 564, and presses against the fourth spring 565. Simultaneously, the pressing rod 567 presses the second button 563, causing the second alarm 562 to sound an alarm.The system reminds staff that support platform 551 has been repositioned, facilitating maintenance. Throughout the inspection process, it can correct any displacement or floating of the workpiece's height and horizontal position, issuing an alarm during correction to remind staff to maintain and repair the equipment. Furthermore, the second alarm 562 and the first alarm 529 have different timbre and loudness settings, allowing for quick identification of parts requiring maintenance. This ensures the accuracy of the workpiece's position during inspection, preventing measurement errors that could lead to missed or misjudged defects, and preventing shape mismatch failures that could result in the rejection of qualified products, thus avoiding the misclassification of qualified products as defective.
[0039] Example 2:
[0040] Please see Figure 10 and Figure 11 As shown, the rejection assembly 7 includes a second cylinder 71, a second piston rod 72 slidably connected to the inner cavity of the second cylinder 71, a rejection rod 73 fixedly installed at the end of the second piston rod 72 away from the second cylinder 71, a push plate 74 fixedly installed on the outer surface of the rejection rod 73, a protrusion 75 fixedly installed at the bottom end of the push plate 74, a buffer mechanism 76 provided on the inner wall of the detection table 1, a collection box 77 fixedly installed on the outer surface of the detection table 1, the middle part of the protrusion 75 protrudes, and both ends of the protrusion 75 are flat surfaces of the same height. The lifting rod 572 is connected via an inclined surface, with its bottom end positioned above the two end planes of the protrusion 75. When the protrusion 75 moves, it drives the lifting plate 571 to rise. The lifting mechanism 57 includes a lifting plate 571, with the lifting rod 572 rotatably connected to its bottom end. A push rod 573 is fixedly mounted on the upper surface of the lifting plate 571, and a fifth spring 574 is sleeved on the outer surface of the push rod 573. A pressure plate 575 is fixedly mounted on the top end of the push rod 573. The pressure plate 575 and the support platform 551 are slidably connected. The support platform 551 and the pressure plate... The upper surface of 575 forms a plane. Push rod 573 and support platform 551 are slidably connected. The fifth spring 574 is located between support platform 551 and lifting plate 571. The middle parts of support base 51, connecting base 53 and base 58 are all hollowed out and do not contact push rod 573. When there is a defective product, support assembly 5 stops on one side of second cylinder 71. At this time, the operation of second cylinder 71 drives second piston rod 72 to extend and retract. The extension and retraction of second piston rod 72 drives rejection rod 73 and push plate 74 to move. The movement of push plate 74 drives protrusion. 75 exerts an upward squeezing force on the lifting rod 572. At this time, the lifting rod 572 drives the lifting plate 571 to move upward. The upward movement of the lifting plate 571 drives the push rod 573 to slide upward in the inner cavity of the support platform 551 and squeeze the fifth spring 574. At this time, the pressure plate 575 lifts the workpiece. When the protrusion 75 is directly below the support platform 551, the rejection rod 73 squeezes the workpiece. At this time, the defective product is pushed to the buffer mechanism 76 for guidance, so that the defective product is collected in the collection box 77 for subsequent maintenance.
[0041] Please see Figure 10 and Figure 12 As shown, the buffer mechanism 76 includes a buffer plate 761, with a guide cylinder 762 rotatably connected to the inner cavity of the buffer plate 761. A buffer rod 763 is fixedly installed at one end of the buffer plate 761, and a sixth spring 764 is sleeved on the outer surface of the buffer rod 763. The buffer rod 763 is slidably connected to the inner cavity of the detection table 1, and the sixth spring 764 is located between the buffer plate 761 and the inner wall of the detection table 1. There is a gap between the buffer plate 761 and the upper surface of the conveyor belt 4, and the buffer plate 761 and the support assembly 5 do not contact each other. The buffer plate 761 is inclined. When the rejection rod 73 pushes the workpiece to the conveyor belt 4, the buffer plate 761 is inclined. On the upper surface of the conveyor belt 4, as the subsequent conveyor belt 4 drives, the workpiece comes into contact with the buffer plate 761 and collides with the buffer plate 761. At this time, the buffer plate 761 drives the buffer rod 763 to slide in the inner cavity of the detection table 1 and squeeze the sixth spring 764. The elastic force of the sixth spring 764 reduces the interaction force between the buffer plate 761 and the workpiece, and guides the workpiece into the belt collection box 77 through the guide cylinder 762. This helps to lift the workpiece in the support table 551, reducing the damage to the workpiece caused by rejection and collision, and reducing the cost of subsequent maintenance.
[0042] In summary, the support component 5 is supported and clamped by the conveyor belt 4, improving its stability. The stepper motor drives the rotating rod 3, which in turn drives the conveyor belt 4 to transport the support component 5, facilitating inspection by the inspection unit 2. The positioning component 6 repositions the support component 5 when it shifts, and simultaneously issues an alarm for subsequent maintenance. When defective products need to be removed, the rejection component 7 removes and collects them, while qualified products are further processed and used. The support base 51 is placed on the upper surface of the conveyor belt 4, and the base 58 is clamped between the two conveyor belts 4 to ensure stable conveying. The first floating mechanism 52 is used to flexibly connect the connecting seat 53 in the inner cavity of the support base 51, so that the connecting seat 53 is flexibly fixed in the inner cavity of the support base 51. When the support base 51 moves to the positioning component 6, the positioning rod 54 is used to check the height of the connecting seat 53 to prevent the height of the shaded pole motor to be tested on the second floating mechanism 55 from not meeting the requirements. When the height of the connecting seat 53 deviates, the first floating mechanism 52 can issue an alarm to facilitate equipment maintenance. For maintenance, the second floating mechanism 55 can be used to clamp and limit the workpiece to be inspected. When the second floating mechanism 55 deviates from the upper surface of the conveyor belt 4, the alarm mechanism 56 can sound an alarm. At the same time, the positioning component 6 repositions the second floating mechanism 55, so that the workpiece can return to its original position to be inspected when it deviates, enabling the workpiece to be inspected accurately and preventing inaccurate inspection data due to positional deviation. The lifting mechanism 57 is used to lift the workpiece when rejecting defective products, so that the workpiece is released from the clamp of the second floating mechanism 55, preventing direct pushing. Product damage increases maintenance costs. When there are defective products, the support assembly 5 stops on one side of the second cylinder 71. At this time, the operation of the second cylinder 71 drives the second piston rod 72 to extend and retract. The extension and retraction of the second piston rod 72 drives the rejection rod 73 and the push plate 74 to move. The movement of the push plate 74 drives the protrusion 75 to lift the workpiece by the lifting mechanism 57. When the protrusion 75 is directly below the support platform 551, the rejection rod 73 squeezes the workpiece. At this time, the defective product is pushed to the buffer mechanism 76 for guidance, so that the defective product is collected in the collection box 77 for subsequent maintenance.
