Description

Technical Field

[0001] This utility model relates to the field of washing machine parts inspection technology, specifically a defect detection device for washing machine lids. Background Technology

[0002] Top-loading washing machines all have a lid, which needs to be inspected for defects during production before it can leave the factory. Currently, visual inspection is generally used. The principle is to capture images of the lid surface with a high-precision industrial camera, combine light source optimization to improve defect contrast, and use techniques such as template matching and texture analysis to identify abnormalities such as foreign objects and stains. The results are compared with preset standards, and the inspection results are displayed in real time on an image display screen for workers on the inspection line to view.

[0003] Because the cover plate has six sides (top, bottom, left, right, front, and back), each side needs to be aligned sequentially with an industrial camera during inspection. However, the cover plate has a certain weight, making manual inspection quite laborious. A search revealed that authorization announcement number CN220063808U discloses a photovoltaic panel defect appearance inspection structure, which also performs defect inspection on the panel. This structure includes a support frame, with a flipping mechanism fixedly connected to one side of the support frame. The flipping mechanism includes a fixed base, with a first cylinder fixedly connected inside the fixed base. A support arm is fixedly connected to the top of the first cylinder, and a first motor is fixedly connected inside the support arm. The output shaft of the first motor is fixedly connected to a fixed block via a coupling. A fixed frame is fixedly connected to the bottom of the fixed block, and a second cylinder is fixedly connected to one side of the bottom of the fixed frame. A clamping plate is fixedly connected to one end of the second cylinder, and a fixed plate is fixedly connected to the other end of the fixed frame.

[0004] This technical solution, through a fixed base, a first cylinder, a support arm, a first motor, a fixed block, a fixed frame, a second cylinder, a clamping plate, and a fixed plate, can flip photovoltaic panels. The support plate, second motor, rotating rod, roller, and conveyor belt can improve the inspection efficiency of photovoltaic panels. However, when using the flipping mechanism in this technical solution to flip the cover plate, only the top, bottom, left, and right sides of the cover plate can be aligned with the industrial camera for inspection. The front and back sides of the cover plate cannot be inspected, requiring workers to still adjust the cover plate's orientation. This prevents truly freeing up workers' hands and hinders full automation of the inspection process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a defect detection device for washing machine lids, which solves the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a defect detection device for a washing machine lid, comprising a main frame and a frame, wherein the main frame is used for conveying a conveyor belt, and a vision inspection component is installed on the frame; a clamping and flipping component for clamping and flipping the lid is provided on the frame; and a steering component for turning the lid is also provided on the frame.

A gear that meshes with the outer side of the slewing support bearing is provided on the output shaft of the geared motor. The top plate is higher than the conveyor belt.

[0007] Preferably, the steering assembly further includes a guide rail slidably connected to the mounting rod and a soft pad bonded to the top of the support plate. The bottom of the guide rail is fixedly connected to a support frame connected to the main frame, and the soft pad completely covers the support plate.

[0008] Preferably, the steering assembly further includes a protective cover covering the slewing support bearing and the gear, the protective cover having a through hole through which the support plate passes, and the protective cover having a fastener for connecting to the top plate.

[0009] Preferably, the steering assembly further includes a second soft pad adhered to the protective cover, the second soft pad being located outside the through hole, springs being uniformly arranged circumferentially on the protective cover, the tops of the springs being connected to a retaining ring, and a third soft pad adhered to the inner ring of the retaining ring, both the second and third soft pads having an annular structure.

[0010] Preferably, the clamping and flipping assembly includes two fixed rods, both located above the conveyor belt.

Then, a geared motor drives a gear to rotate, causing the outer ring of the meshing rotary support bearing to rotate the support plate, allowing the lid to rotate and complete the steering. This, combined with the clamping and flipping mechanism, enables comprehensive inspection of the lid without manual operation, freeing up hands and improving inspection efficiency.

[0013] 2. This washing machine lid defect detection device, through the soft pad two, spring, retaining ring and soft pad three in the steering assembly, can prevent the lid from detaching from soft pad one when the support plate rotates at high speed unexpectedly. The retaining ring can prevent the lid from being damaged by soft pad two and soft pad three, thereby improving the safety of the detection process and better protecting the lid. The spring allows the retaining ring to rise and fall without affecting the downward movement of the fixing rod to place the lid on soft pad one. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] See Figures 1-4 This utility model provides the following three technical solutions: First implementation: A defect detection device for a washing machine lid includes a main frame 1 and a frame 3. The main frame 1 is used to convey a conveyor belt 2. A vision inspection component 4 is installed on the frame 3. The main frame 1 is also equipped with a controller 32 and an image display screen 33. The controller 32 is used by the worker to control the components. The vision inspection component 4 detects defects in the appearance of the lid and displays the real-time image on the image display screen 33. The frame 3 is equipped with a clamping and flipping component 5 for clamping and flipping the lid. The frame 3 is also equipped with a steering component 6 for turning the lid. The steering assembly 6 includes a hydraulic telescopic rod 7 detachably connected to the frame 3. The piston rod of the hydraulic telescopic rod 7 is connected to the mounting rod 8, which is used to drive the mounting rod 8 to move back and forth so that the support plate 12 can be moved above the conveyor belt 2 to catch the cover plate. A top plate 9 is fixedly connected to the mounting rod 8. A geared motor 10 and a slewing support bearing 11 are detachably connected to the top plate 9. The inner ring of the slewing support bearing 11 is fixedly connected to the top plate 9, and the outer ring of the slewing support bearing 11 is connected to the support plate 12. A gear 13 is provided on the output shaft of the geared motor 10, which meshes with the outer side of the slewing support bearing 11. By driving the gear 13 to rotate through the geared motor 10, the outer ring of the slewing support bearing 11 rotates on its inner ring, thereby driving the support plate 12 to rotate. In order to move the top plate 9 to the upper side of the conveyor belt 2, the top plate 9 is higher than the conveyor belt 2.

[0018] The steering assembly 6 also includes a guide rail 14 slidably connected to the mounting rod 8 and a soft pad 16 bonded to the top of the support plate 12. The bottom of the guide rail 14 is fixedly connected to a support frame 15 connected to the main frame 1. The soft pad 16 completely covers the support plate 12. The soft pad 16 is set so that when the cover plate is lowered, a large collision between the cover plate and the support plate 12 can be avoided, thus better protecting the cover plate. The guide rail 14 can guide the mounting rod 8, avoiding the need for the hydraulic telescopic rod 7 to bear the force alone.

[0019] The clamping and flipping assembly 5 includes two fixed rods 24, both located above the conveyor belt 2. Each fixed rod 24 is detachably connected to an electric telescopic rod 25. The power supply for the electric telescopic rod 25 is installed on the fixed rod 24, preventing cable entanglement during subsequent rotation. A clamping rod 26 is provided at the output end of the electric telescopic rod 25, used to clamp or release the rod. To increase clamping stability, anti-slip pads 27 are adhered to both clamping rods 26. To enable the two fixed rods 24 to flip together, a U-shaped connecting rod 28 connects them. The U-shaped connecting rod 28 ensures that the side wall of the cover plate is not blocked when rotating vertically. The rear fixed rod 24 is connected to the output shaft of a second reduction motor 29, which is detachably connected to the base 30. An electric guide rail 31 for lifting the base 30 is provided on the frame 3. The electric guide rail 31 drives the base 30 to rise and fall, which in turn causes the geared motor 29 and the cover plate to rise and fall. After rising, there is space to flip the cover plate.

[0020] The second embodiment differs from the first embodiment in that the steering assembly 6 further includes a protective cover 17 covering the slewing support bearing 11 and the gear 13. The protective cover 17 has a through hole 18 through which the support plate 12 passes. The protective cover 17 is provided with a fastener 19 for connecting with the top plate 9. The protective cover 17 is installed by the fastener 19, which can shield the slewing support bearing 11 and the gear 13 to prevent worker injury during rotation. The through hole 18 does not affect the rotation of the support plate 12.

[0021] When the support plate 12 rotates at high speed unexpectedly, causing the cover plate to detach from the pad 16, the cover plate will fly out, which is extremely dangerous. Therefore, a third implementation method is provided.

[0022] The third implementation differs from the second implementation in that the steering assembly 6 also includes a second soft pad 20 bonded to the protective cover 17. The second soft pad 20 is located outside the through hole 18, providing cushioning protection for the cover plate when it falls. Springs 21 are evenly arranged circumferentially on the protective cover 17, with the top of each spring 21 connected to a retaining ring 22. A third soft pad 23 is bonded to the inner ring of the retaining ring 22. Both the second soft pad 20 and the third soft pad 23 have an annular structure, providing cushioning protection for the cover plate before it impacts the retaining ring 22. If the cover plate accidentally flies out, it can be blocked by the retaining ring 22 and prevented from being damaged by the second soft pad 20 and the third soft pad 23, thus improving safety during the testing process and better protecting the cover plate. The springs 21 allow the retaining ring 22 to rise and fall without affecting the downward movement of the fixing rod 24 to place the cover plate on the first soft pad 16.

[0023] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0024] In use, the cover plates are conveyed one by one via conveyor belt 2. After being conveyed to the inspection position, one side is visually inspected. Then, the clamping rods 26 on both sides clamp the cover plate and move it upward away from conveyor belt 2. Then, the cover plate is flipped to perform visual inspection on the other three sides. Finally, the hydraulic telescopic rod 7 moves the support plate 12 above the conveyor belt 2 and below the cover plate, so that the cover plate can be lowered onto the soft pad 16. At this time, the support plate 12 rotates to rotate the cover plate to complete the turning. After turning, the clamping rods 26 on both sides clamp the cover plate and move it upward away from conveyor belt 2. At this time, the support plate 12 moves forward and the cover plate is flipped to perform visual inspection on the last two sides. After the inspection is completed, the cover plate is put back on conveyor belt 2 and the visual inspection of the next cover plate begins.
