Description

Technical Field

[0001] The present invention relates to the technical field of visual analysis and detection, and in particular to an appearance detection device for producing air conditioner liquid storage containers. Background Art

[0002] The air conditioner liquid receiver is a key component in the refrigeration system. It is installed between the condenser and the evaporator and is used to store excess refrigerant during refrigeration operation. During the production process of the liquid receiver, an appearance inspection device is required to inspect the surface quality of the liquid receiver. Image acquisition and visual recognition analysis are used to achieve inspection. The surface of the liquid receiver is photographed from multiple angles using a high-definition camera or an industrial camera to capture surface scratches, dents, rust, weld defects and other appearance defects. The collected images are analyzed and compared to quickly determine whether the product is qualified. It also has a rejection function for unqualified products, effectively replacing traditional manual visual inspection.

[0003] After searching, a battery appearance inspection device with announcement number CN116380920B proposed an appearance inspection device, including a support mechanism, which includes 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. The top of the support plate is fixedly connected to a mounting plate, and a driving component is provided on the inner side of the mounting plate. The equipment can not only ensure that the inspection product is stably fixed, but also cooperate with the reciprocating swinging sampling and shooting camera to further improve the sampling effect of the appearance of the inspection product and ensure the inspection effect. Moreover, since the time for the equipment to inspect the inspection product is judged by whether the disc is rotating, it can ensure that each inspection product has sufficient time to be inspected. While the equipment is inspecting the first group of inspection products, the next group of inspection products can be installed on the next group of counterweight chucks. When replacing, it is more convenient and quick, and there is no need to control the motor.

[0004] The above patent still has shortcomings in actual use. When inspecting the outer tube of the air-conditioning liquid reservoir, the outer surface of the liquid reservoir is mostly inspected for flaws and defects. More obvious defects such as welding leaks and dents can be identified more accurately. However, during the production process of the air-conditioning liquid reservoir before inspection, the outer surface may be stained. During visual inspection, the images of small flaws and stains are extremely similar and difficult to distinguish. It is easy to mistake stains for defects and identify them as defective products, resulting in a high defective rate in the overall production, and also increasing the workload of post-processing.

The system pre-processes, extracts features and compares and analyzes the collected images, and quickly determines whether the product is qualified based on the preset quality standard model. The reservoir is placed on the inspection table 14 on the stand 11, and the inspection table 14 rotates. The inspection mechanism 13 performs a full range of visual analysis and inspection on the outer surface of the reservoir to detect whether there are any defects and flaws on the outer surface of the reservoir. The electric push rod 21 pushes the slide 22 to slide along the side frame 15 until the decontamination paper 25 fits on the reservoir.

During the movement, the rack 1 310 will drive the gear 1 38 to rotate, and the gear 1 38 will drive the vertical rod 35 to rotate. The ring 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 to drive the ring 34 to rise to a position flush with the stain, which has the effect of adjusting the height of the stain-removing paper 25, making it convenient for the stain-removing paper 25 to be aligned with the stain. The stain-removing paper 25 of appropriate width can be used to avoid unnecessary waste.

During the sliding process of trapezoidal block 47, it will drive rack 2 48 to engage gear 2 46, and then drive gear 2 46 to rotate. Gear 2 46 drives the flip rod 43 to flip through the shaft 42 and drives the arc plate 44 to cover the outer surface of the liquid reservoir. The rubber roller 45 abuts against the outer surface of the liquid reservoir to achieve the effect of positioning the liquid reservoir, avoiding the movement of the liquid reservoir due to force during the wiping process, and improving the stability during the wiping process.

[0024] like Figure 2 、 Figure 3 、 Figure 6 、 Figure 9 and Figure 10 As shown, the humidifying unit includes a water storage barrel 51, a pumping pipe 52 and a spray gun 53. The pumping pipe 52 is provided at the end of the water storage barrel 51. Transparent wiping oil is provided inside the water storage barrel 51. The end of the pumping pipe 52 away from the water storage barrel 51 is connected to the spray gun 53. The spray gun 53 is fixedly connected to the upper surface of the side frame 15. A trigger assembly is provided on the lower surface of the spray gun 53, and a swing assembly is provided at the end of the spray gun 53. The trigger assembly includes a vertical rod 62 rotatably connected to the lower surface of the spray gun 53. The outer surface of the vertical rod 62 is fixedly sleeved with a turntable 63. The upper surface of the turntable 63 is penetrated by an arc-shaped groove 66. A pressing rod 65 is fixedly connected to the wrench of the spray gun 53. The end of the pressing rod 65 away from the wrench of the spray gun 53 is movably engaged in the inside of the arc-shaped groove 66.

The end of the swing rod 73 away from the atomizing nozzle 72 is fixedly connected to the side of the turntable 63. During the backward movement of the slide 22, the push rod 61 pushes the extension plate 64, thereby driving the vertical rod 62 and the turntable 63 to rotate, and at the same time, compressing the torsion spring 67. During the rotation of the turntable 63, the pressing rod 65 is driven to move and press the wrench of the spray gun 53. The spray gun 53 sprays transparent wiping oil and sprinkles it on the outer surface of the replaced cleaning paper 25, thereby wetting the cleaning paper 25. The transparent wiping oil has a good decontamination effect and improves the effectiveness of the cleaning paper 25 in removing stains. During the rotation of the turntable 63, the rocker 73 drives the atomizing nozzle 72 to swing, expanding the spraying range, ensuring the uniformity of the spraying, and improving the cleaning range of the cleaning paper 25. The swinging spraying of the atomizing nozzle 72 can ensure that the outer surface of the cleaning paper 25 is slightly soaked while avoiding local excessive soaking, thereby achieving a uniform cleaning effect. The transparent wiping oil is an existing transparent anti-rust oil. While cleaning the metal surface, it can also form a protective film to prevent metal oxidation and rust.

[0025] The technical solution provided by the present invention is that when performing a visual analysis and inspection of the appearance of the air-conditioning liquid reservoir, the liquid reservoir is placed on the inspection table 14 on the base 11. The inspection table 14 has a built-in rotation function. During the rotation, the inspection mechanism 13 performs a full range of visual analysis and inspection on the outer surface of the liquid reservoir to detect whether there are flaws and defects on the outer surface of the liquid reservoir. If flaws and defects are detected, the staff will be reminded and the product will be removed as a defective product. During the visual analysis and inspection process, since some flaws and stains are extremely similar in appearance, confusion may easily occur. When such a situation is detected, the inspection table 14 rotates one hundred and eighty degrees to align the side with the flaw or stain with the decontamination paper 25, and at the same time, the electric push rod 21 pushes the slide 22 to slide along the side frame 15. At the same time, the slide 22 will drive the adjustment component and the folding plate 23 and other structures to move toward the liquid reservoir until the decontamination paper When the cam 35 is in the working state, the cam 35 is in the working state, and the cam 35 is in the working state, so that the cam 35 is in the working state, and the cam 35 is in the working state, so that the cam 35 is in the working state, and the cam 35 is in the working state, so that the cam 35 is in the working state, and the cam 35 is in the working state, so that the cam 35 is in the working state, and the cam 35 is in the working state, so that the cam 35 is in the working state, and the cam 35 is in the working state, so that the cam 35 is in the working state, and the cam 35 is in the working state, so that the cam 35 is in the working state, and the cam 35 is in the working state, so that the cam 35 is in the working state, and the cam 35 is in the working state, so that the cam 35 is in the working state, and the cam 35 is in the working state, so that the cam 35 is in the working state, and the cam 35 is in the working state, so that the cam 35 is in the working state, and the cam 35 is in the working state, so that the cam 35 is in the working state, During the forward movement of rack 1 310, it will contact the inclined plate of trapezoidal block 47 and push the trapezoidal block 47 to move along the guide rod 411 toward the end seat 409 and squeeze the damping spring 410. During the sliding process of trapezoidal block 47, it will drive rack 2 48 to mesh with gear 2 46, and then drive gear 2 46 to rotate. Gear 2 46 drives the turning rod 43 to turn over through the shaft 42 and drives the arc plate 44 to cover the outer surface of the liquid reservoir. The rubber roller 45 abuts against the outer surface of the liquid reservoir to achieve the effect of positioning the liquid reservoir, avoiding In order to avoid the liquid reservoir from moving due to force during the wiping process, the detection table 14 drives the liquid reservoir to swing back and forth slightly to achieve relative movement with the decontamination paper 25, thereby wiping the part. If it can be wiped away, it means it is a stain. After another visual analysis and inspection, if there is no abnormality, it will pass the inspection. If it cannot be wiped away, it means it is a defect and is classified as a defective product. This has the effect of distinguishing stains from defective products, avoiding treating stains as defective products, and reducing the defective rate in the product production process. After wiping is completed, the electric push rod 21 drives the slide 22 to move backward, and the slide 22 slides along the side frame 15 and drives the folding plate 23 away from the base 11. Under the action of the reset spring 33, the folding plate 23 will continue to be squeezed against the side of the base 11, and the inner rod 32 slides along the cylinder 31, while driving the rack 310 to move, driving the gear 38 to rotate so that the ring 34 drops to the initial position, and the rebound of the damping spring 410 pushes the trapezoidal block 47 to move, so that the flip rod 43 flips , loosen the limit of the liquid reservoir, and then when the folding plate 23 moves back, the ratchet 26 will encounter the pawl 28 and rotate at the limit of the pawl 28, thereby driving the reel-up shaft 24 to rotate and reel in the decontamination paper 25. The other reel-up shaft 24 rotates and releases the decontamination paper 25, thereby achieving the effect of replacing the decontamination paper 25. Moreover, since the ratchet 26 and the pawl 28 are unidirectional motions, they slide relative to each other when the ratchet 26 moves forward, avoiding excessive replacement of the decontamination paper 25. In addition, during the backward movement of the slide 22, the push rod 61 will push the extension plate 64 and then drive the vertical rod 62 and the turntable 63 to rotate, and at the same time squeeze the torsion spring 67. During the rotation of the turntable 63, the pressing rod 65 will be driven to move and press the wrench of the spray gun 53 to start the spray gun 53. The transparent wiping oil is sucked out of the water storage barrel 51 by the pump suction pipe and transported to the spray gun 53. After pressing the wrench, the spray gun 53 will spray the transparent wiping oil and sprinkle it on the surface of the replaced decontamination paper 25. The surface can achieve the effect of wetting the decontamination paper 25, improve the effect of removing stains of the decontamination paper 25, and facilitate the removal of stains. During the rotation of the turntable 63, the rocker arm 73 will drive the atomizing nozzle 72 to swing, expand the spraying range, ensure the uniformity of spraying, and improve the cleaning range of the decontamination paper 25. When the next liquid reservoir visual analysis inspection is carried out and identification is required, the above movement is repeated. After the top rod 61 is moved away, the turntable 63 and the vertical rod 62 will be driven to rotate and reset under the action of the torsion spring 67.
