Description

Technical Field

[0001] This invention relates to the field of visual analysis and inspection technology, and more specifically, to an appearance inspection device for the production of air conditioning liquid receivers. Background Technology

[0002] Air conditioning receivers are key components in refrigeration systems, installed between the condenser and evaporator to store excess refrigerant during refrigeration operation. During the production of receivers, visual inspection devices are required to check the surface quality. This inspection utilizes image acquisition and visual recognition analysis, taking multi-angle photos of the receiver surface using high-definition cameras or industrial cameras to capture surface scratches, dents, rust, weld defects, and other appearance flaws. The acquired images are analyzed and compared to quickly determine product quality. The system also has a rejection function for non-conforming products, effectively replacing traditional manual visual inspection.

[0003] A search revealed a battery appearance inspection device (CN116380920B), which includes a support mechanism comprising a cabinet, a support frame fixedly connected to the top of the cabinet, and a support plate fixedly connected to the top of the support frame. A mounting plate is fixedly connected to the top of the support plate, and a driving component is located on the inner side of the mounting plate. This device not only ensures stable fixation of the inspection items but also, in conjunction with a reciprocating oscillating sampling camera, further improves the sampling effect on the appearance of the inspection items, ensuring effective inspection. Furthermore, since the inspection time is determined by whether the disc rotates, sufficient time is ensured for each item to be inspected. While the device is inspecting the first set of items, the next set can be installed on the next set of counterweight chucks, making replacement more convenient and faster without requiring motor control.

[0004] The aforementioned patents still have shortcomings in practical use. When inspecting the outer pipe of an air conditioner liquid receiver, the inspection mainly focuses on whether there are any defects or flaws on the outer surface of the liquid receiver. While more obvious defects such as missing welds or dents can be identified relatively accurately, the outer surface of the air conditioner liquid receiver may become stained during the production process before inspection. During visual inspection, the images of small defects and stains are extremely similar and difficult to distinguish. This can easily lead to stains being mistaken for defects and identified as defective products, resulting in a high overall defect rate in production and increasing the workload of subsequent processing.

[0005] Based on this, the present invention discloses an appearance inspection device for the production of air conditioner liquid receivers. Summary of the Invention

[0012] As a further improvement to this technical solution, both take-up shafts are rotatably sleeved on the outer surface of the collar. The two take-up shafts are respectively the winding shaft and the unwinding shaft. A ratchet is fixedly sleeved on the bottom outer surface of the winding shaft. A side rod is fixedly connected to the side of the side frame. Pads are evenly distributed at the end of the side rod away from the side frame.

[0013] As a further improvement to this technical solution, the humidification unit includes a water storage tank, a pumping pipe, and a spray gun. The pumping pipe is located at the end of the water storage tank, and the end of the pumping pipe away from the water storage tank is connected to the spray gun.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Therefore, the present invention provides an appearance inspection device for the production of air conditioner liquid receivers. See [link to relevant documentation]. Figures 1 to 10 As shown, it includes a detection unit and a cleaning unit;

[0035] The detection unit includes a base 11, a support 12, a detection mechanism 13, a detection table 14, and a side frame 15. The support 12 is fixedly connected to the upper surface of the base 11, the detection mechanism 13 is movably connected to the outer surface of the support 12, the detection table 14 is movably disposed on the upper surface of the base 11, and the side frame 15 is fixedly connected to the side of the base 11. The detection mechanism 13 is a visual inspection device. The specific structure and operating principle of the device are existing technologies well known to those skilled in the art and will not be elaborated in detail here.

[0036] The cleaning unit includes an electric push rod 21 disposed on the outer surface of the side frame 15, a slide seat 22 slidably connected to the outer surface of the side frame 15, a drive end of the electric push rod 21 fixedly connected to the slide seat 22, a folding plate 23 disposed on the side of the slide seat 22, two take-up shafts 24 disposed on the upper surface of the folding plate 23, a cleaning paper 25 disposed on the outer surface of the take-up shafts 24, both take-up shafts 24 being rotatably sleeved on the outer surface of the collar 34, the two take-up shafts 24 being a winding shaft and a feeding shaft respectively, a ratchet 26 fixedly sleeved on the bottom outer surface of the winding shaft, a side rod 27 fixedly connected to the side of the side frame 15, pawls 28 evenly distributed at the end of the side rod 27 away from the side frame 15, an adjustment component disposed on the outer surface of the folding plate 23, a positioning component disposed on the upper surface of the platform 11, and a humidification unit disposed on the outer surface of the side frame 15;

[0037] During the visual analysis and inspection of the air conditioner liquid receiver, a high-definition camera is used to capture multi-angle real-time images of the liquid receiver, accurately capturing surface scratches, dents, rust, weld defects, and other appearance flaws. The captured images are directly uploaded to the system, which stores a large image library containing numerous photos of these flaws. The system preprocesses, extracts features, and performs comparative analysis on the collected images. Based on a preset quality standard model, it quickly determines whether the product is qualified. The liquid receiver is placed on the inspection table 14 on the base 11. The inspection table 14 rotates, and the inspection mechanism 13 performs a comprehensive visual analysis and inspection of the outer surface of the liquid receiver to detect any flaws or defects. The electric push rod 21 pushes the slide 22 to slide along the side frame 15 until the cleaning paper 25 adheres to the liquid receiver. On the outer surface, the inspection platform 14 drives the liquid reservoir to swing back and forth slightly, which can achieve relative movement with the cleaning paper 25, thus wiping the part. If it can be wiped off, it means that it is a stain. After visual analysis and inspection, if there is no abnormality, it will pass the inspection. If it cannot be wiped off, it means that it is a defect and is classified as a defective product. This can distinguish between stains and defective products, avoid treating stains as defective products, and reduce the defect rate in the product production process. After wiping, the electric push rod 21 drives the slide 22 to move backward, and the ratchet 26 rotates at the limit of the pawl 28. This drives the take-up shaft 24 to rotate and take up the cleaning paper 25. The other take-up shaft 24 rotates and releases the cleaning paper 25, thus achieving the effect of replacing the cleaning paper 25.

[0038] like Figures 2 to 5As shown, the adjusting assembly includes a vertical rod 35 that is movably inserted through the outer surface of the folded plate 23. A collar 34 is movably fitted onto the outer surface of the vertical rod 35. A cylinder 31 is fixedly connected to the side of the slide block 22. An inner rod 32 is fixedly connected to the side of the folded plate 23. The inner rod 32 is movably inserted into the inside of the cylinder 31. A return spring 33 is provided inside the cylinder 31. The return spring 33 abuts against the end of the inner rod 32 that extends into the cylinder 31. A connecting rod is fixedly connected to the outer surface of the cylinder 31. A rack 310 is fixedly connected to the end of the rod 39 away from the cylinder 31. A gear 38 is fixedly connected to the bottom end of the vertical rod 35. The gear 38 meshes with the rack 310. A track 36 is provided on the outer surface of the vertical rod 35. A slider 37 is fixedly connected to the inner wall of the collar 34. The slider 37 slides inside the track 36. A telescopic rod 311 is provided on the side of the collar 34. The bottom end of the telescopic rod 311 is fixedly connected to the upper surface of the folded plate 23.

[0039] As the electric actuator 21 continues to push, it forces the inner rod 32 to slide into the cylinder 31 and compress the return spring 33. The movement of the cylinder 31 will drive the rack 310 to continue moving towards the detection table 14 via the connecting rod 39. During the movement, the rack 310 will drive the gear 38 to rotate, and the gear 38 will drive the vertical rod 35 to rotate. The collar 34 is limited by the telescopic rod 311. Therefore, during the rotation of the vertical rod 35, the slider 37 moves along the track 36 and drives the collar 34 to rise to the same position as the stain, which has the effect of adjusting the height of the cleaning paper 25, making it convenient for the cleaning paper 25 to be aligned with the stain. Only a cleaning paper 25 of appropriate width is needed to avoid unnecessary waste.

[0040] like Figure 2 , Figure 7 and Figure 8 As shown, the positioning assembly includes a support 41 fixedly connected to the upper surface of the base 11, a shaft 42 rotatably connected to the middle of the support 41, a flip rod 43 fixedly connected to the outer surface of the shaft 42, an arc plate 44 fixedly connected to the end of the flip rod 43 away from the shaft 42, rubber rollers 45 evenly distributed on the outer surface of the arc plate 44, a trapezoidal block 47 slidably connected to the upper surface of the base 11, a rack 48 embedded in the upper surface of the trapezoidal block 47, a gear 46 fixedly connected to the end of the shaft 42, the gear 46 meshing with the rack 48, an end seat 49 fixedly connected to the upper surface of the base 11, a damping spring 410 between the end seat 49 and the trapezoidal block 47, a guide rod 411 fixedly connected to the side of the trapezoidal block 47, and the guide rod 411 movably passing through the outer surface of the end seat 49.

[0041] As rack 310 moves forward, it contacts the inclined plate of trapezoidal block 47 and pushes trapezoidal block 47 along guide rod 411 toward end seat 49, compressing damping spring 410. During the sliding process of trapezoidal block 47, rack 48 engages gear 46, which in turn drives gear 46 to rotate. Gear 46 drives flipping rod 43 to flip through shaft 42 and causes arc plate 44 to cover the outer surface of liquid reservoir. Rubber roller 45 abuts against the outer surface of liquid reservoir, achieving the effect of positioning liquid reservoir and preventing liquid reservoir from moving due to force during wiping, thus improving stability during wiping.

[0042] like Figure 2 , Figure 3 , Figure 6 , Figure 9 and Figure 10 As shown, the humidification unit includes a water tank 51, a pump pipe 52, and a spray gun 53. The pump pipe 52 is located at the end of the water tank 51. The water tank 51 is filled with wiping liquid. The end of the pump pipe 52 away from the water tank 51 is connected to the spray gun 53. The spray gun 53 is fixedly connected to the upper surface of the side frame 15. The lower surface of the spray gun 53 is provided with a triggering component, and the end of the spray gun 53 is provided with a swinging component.

[0043] The triggering assembly includes a vertical rod 62 rotatably connected to the lower surface of the spray gun 53, a turntable 63 fixedly sleeved on the outer surface of the vertical rod 62, an arc-shaped groove 66 extending through the upper surface of the turntable 63, a pressing rod 65 fixedly connected to the handle of the spray gun 53, the end of the pressing rod 65 away from the handle of the spray gun 53 being movably engaged inside the arc-shaped groove 66, a top rod 61 fixedly connected to the upper surface of the slide block 22, an extension plate 64 fixedly connected to the outer surface of the bottom end of the vertical rod 62, a torsion spring 67 sleeved on the outer surface of the vertical rod 62, and the end of the torsion spring 67 away from the vertical rod 62 being fixedly connected to the lower surface of the spray gun 53.

[0044] The swing assembly includes a bellows 71 disposed at the end of the spray gun 53, an atomizing nozzle 72 fixedly connected to the end of the bellows 71, a swing arm 73 fixedly connected to the lower surface of the atomizing nozzle 72, and the end of the swing arm 73 away from the atomizing nozzle 72 fixedly connected to the side of the turntable 63.

[0045] During the backward movement of the slide block 22, the push rod 61 pushes the extension plate 64, which in turn drives the vertical rod 62 and the turntable 63 to rotate. At the same time, it compresses the torsion spring 67. During the rotation of the turntable 63, it drives the pressing rod 65 to move and press the wrench of the spray gun 53. The spray gun 53 sprays the wiping liquid onto the outer surface of the replaced cleaning paper 25, achieving the effect of wetting the cleaning paper 25. The wiping liquid is made of a certain proportion of water and alcohol, which has a good cleaning effect and also has the characteristics of alcohol quick drying, improving the effect of cleaning the cleaning paper 25 in removing stains. During the rotation of the turntable 63, it drives the atomizing nozzle 72 to swing through the swing rod 73, expanding the spray range and ensuring the uniformity of the spray, thus improving the cleaning range of the cleaning paper 25. The swinging spray of the atomizing nozzle 72 can ensure that the outer surface of the cleaning paper 25 is slightly wetted while avoiding excessive local wetting. It can both remove stains and avoid the situation where the wiping liquid cannot dry quickly due to excessive moisture.

[0046] The technical solution provided by this invention involves visually analyzing and inspecting the appearance of an air conditioner liquid receiver. The receiver is placed on a testing platform 14 on a base 11. The testing platform 14 has a built-in rotation function. During rotation, the testing mechanism 13 performs a comprehensive visual analysis of the receiver's outer surface to detect any defects or flaws. If defects or flaws are detected, the operator is alerted and the receiver is removed from the defective products category. During visual analysis and inspection, some defects and stains are very similar in appearance and can easily cause confusion. In such cases, the testing platform 14 rotates 180 degrees to align the side with the defective or stained area with the cleaning paper 25. Simultaneously, the electric push rod 21 pushes the slide 22 to slide along the side frame 15. The slide 22 also moves the adjusting components and the folding plate 23 towards the receiver until the cleaning paper... 25 is attached to the outer surface of the reservoir. At this time, the folding plate 23 also abuts against the side of the platform 11. The electric push rod 21 continues to push, which will force the inner rod 32 to slide into the inside of the cylinder 31 and squeeze the return spring 33. The movement of the cylinder 31 will drive the rack 310 to continue to move towards the detection platform 14 through the connecting rod 39. During the movement, the rack 310 will drive the gear 38 to rotate. The gear 38 will drive the vertical rod 35 to rotate. Since the slider 37 inside the collar 34 is slidably connected to the inside of the track 36, and the collar 34 is also limited by the telescopic rod 311, during the rotation of the vertical rod 35, the slider 37 moves along the track 36 and drives the collar 34 to rise to the same position as the stain. This has the effect of adjusting the height of the cleaning paper 25, making it convenient for the cleaning paper 25 to be aligned with the stain. A cleaning paper 25 of appropriate width can be used to avoid unnecessary waste.

[0047] During the forward movement of rack 310, it contacts the inclined plate of trapezoidal block 47 and pushes trapezoidal block 47 along guide rod 411 towards end seat 49, compressing damping spring 410. During the sliding of trapezoidal block 47, rack 48 engages gear 46, which in turn drives gear 46 to rotate. Gear 46, via shaft 42, drives flipping rod 43 to flip and causes arc plate 44 to cover the outer surface of the reservoir. Rubber roller 45 abuts against the outer surface of the reservoir, achieving the effect of positioning the reservoir and preventing... During the wiping process, the liquid reservoir moves due to the force. The detection platform 14 drives the liquid reservoir to swing back and forth slightly, which can achieve relative movement with the cleaning paper 25, thus achieving the effect of wiping the part. If it can be wiped off, it means that it is a stain. After visual analysis and inspection, if there is no abnormality, it will pass the inspection. If it cannot be wiped off, it means that it is a defect and is classified as a defective product. This has the effect of distinguishing between stains and defective products, avoiding the treatment of stains as defective products, and reducing the defect rate in the product production process.

[0048] After wiping, the electric actuator 21 drives the slide 22 to move backward. The slide 22 slides along the side frame 15 and moves the folding plate 23 away from the platform 11. Under the action of the return spring 33, the folding plate 23 will continue to be pressed against the side of the platform 11. The inner rod 32 slides along the inside of the cylinder 31, while driving the rack 310 to move and the drive gear 38 to rotate, thereby causing the collar 34 to descend to the initial position. The rebound of the damping spring 410 will push the trapezoidal block 47 to move, thereby causing the flipping rod 43 to flip. The ratchet 26 rotates, releasing the limit on the liquid reservoir. Then, as the folding plate 23 moves back, the ratchet 26 encounters the pawl 28 and rotates within the limit of the pawl 28. This drives the take-up shaft 24 to rotate and take up the cleaning paper 25. The other take-up shaft 24 rotates as well, releasing the cleaning paper 25, thus achieving the effect of replacing the cleaning paper 25. Furthermore, since the ratchet 26 and pawl 28 move in one direction, they slide relative to each other as the ratchet 26 moves forward, preventing over-replacement of the cleaning paper 25. Furthermore, during the backward movement of the slide block 22, the push rod 61 pushes the extension plate 64, which in turn drives the vertical rod 62 and the turntable 63 to rotate. At the same time, it compresses the torsion spring 67. During the rotation of the turntable 63, it drives the pressing rod 65 to move and press the wrench of the spray gun 53, thereby activating the spray gun 53. The wiping liquid is drawn from the water tank 51 by the pump suction pipe and transported to the spray gun 53. After pressing the wrench, the spray gun 53 will spray the wiping liquid onto the outer surface of the replaced cleaning paper 25. This achieves the effect of wetting the cleaning paper 25, improving the cleaning effect of the cleaning paper 25 in removing stains, and making it easier to remove stains. During the rotation of the turntable 63, the atomizing nozzle 72 will swing through the swing rod 73 to expand the spraying range, ensure the uniformity of spraying, and improve the cleaning range of the cleaning paper 25. When the next reservoir visual analysis and detection is required and identification is needed, the above movement is repeated. After the top rod 61 moves away, the turntable 63 and the vertical rod 62 will be driven to rotate and reset under the action of the torsion spring 67.
