[0039] Figure 1 This is a schematic structural diagram of an air conditioner appearance inspection device 100 according to an embodiment of the present utility model. Figure 1 As shown, in one specific embodiment, the air conditioner appearance inspection equipment 100 includes a conveying device 10, multiple hanging brackets 20, and at least one visual inspection device 30. The conveying device 10 extends along the conveying direction. Multiple hanging brackets 20 are suspended at intervals on the conveying device 10 along the conveying direction and are transported along the conveying direction by the conveying device 10. Each hanging bracket 20 is used to attach at least one air conditioner panel 200 to be inspected. Each visual inspection device 30 is located on one side of the conveying device 10 perpendicular to the conveying direction and includes at least one camera component. Each camera component is configured to acquire an image of at least one air conditioner panel 200 on each hanging bracket 20 when it moves to a target position and to count the air conditioner panels 200. Here, the air conditioner panel 200 is a sheet metal part of the air conditioner outdoor unit. The air conditioner appearance inspection equipment 100 also includes a standard database storing preset images. After the camera component acquires an image of the air conditioner panel 200 to be inspected, it compares the image with the preset images in the standard database to determine whether the air conditioner panel 200 is qualified.

[0040] This embodiment suspends the air conditioning panel 200 on the transmission bracket device 20, and uses the visual inspection device 30 to inspect the appearance of the air conditioning panel 200 and count the air conditioning panel 200, thereby realizing automated inspection and counting. Compared with manual inspection, it improves the inspection efficiency of the air conditioning panel 200 and the inspection accuracy.

[0041] In some embodiments, the camera component analyzes the acquired image of the air conditioning panel 200 using an image processing acquisition method, comparing it with images in the standard database of air conditioning panels 200 to determine whether the air conditioning panel 200 meets the requirements. Furthermore, the camera component counts each air conditioning panel 200 it detects; once all air conditioning panels 200 have been detected, the total number of air conditioning panels 200 can be determined based on the count.

[0042] In some embodiments, at least one mounting bracket 20 has multiple air conditioning panels 200 attached to it, and the multiple air conditioning panels 200 are respectively located on both sides of the mounting bracket 20 perpendicular to the conveying direction. Multiple visual inspection devices 30 are included, and the multiple visual inspection devices 30 are respectively located on both sides of the conveying device 10 perpendicular to the conveying direction, to acquire images of the air conditioning panels 200 on both sides of the mounting bracket 20.

[0043] This embodiment is equivalent to the bracket device 20 being able to simultaneously transport two rows of air conditioning panels 200. The visual inspection devices 30 on both sides of the conveying device 10 can simultaneously inspect the two rows of air conditioning panels 200, thereby improving the inspection efficiency.

[0044] In some embodiments, a visual inspection device 30 can be provided on both sides of the conveying device 10. When each mounting device 20 moves to the target position, a visual inspection device 30 can inspect the air conditioning panel 200 on one side of the mounting device 20, that is, acquire an image of the air conditioning panel 200 on one side of the mounting device 20 and compare the image with a pre-stored preset image.

[0045] Figure 2 yes Figure 1 The diagram shows a schematic structural diagram of the mounting bracket 20 of the air conditioner appearance inspection equipment 100. Figure 3 yes Figure 1 A schematic, partially enlarged view of the support frame 24 of the hanging device 20 shown. Figure 2 and Figure 3 As shown, in some embodiments, each mounting bracket 20 includes a vertically extending main rod 21 and at least one support assembly 22 connected to the main rod 21. Each support assembly 22 includes a plurality of support rods 23 and two support frames 24. The plurality of support rods 23 are respectively arranged on both sides of the main rod 21 perpendicular to the conveying direction and extend obliquely upward from the main rod 21. The two support frames 24 are respectively arranged on both sides of the main rod 21 perpendicular to the conveying direction and connected to the support rods 23 located on the same side of the main rod 21. The air conditioning panel 200 is hung on the support frame 24 along the conveying direction.

[0046] In this embodiment, the support rod 23 is designed to extend diagonally upwards. Compared with the horizontally extending support rod 23, it has better structural strength and can improve the stability of the air conditioning panel 200.

[0047] In some embodiments, each support frame 24 may have a corresponding support rod 23. That is, each support assembly 22 may include two support rods 23 and two support frames 24, with the two support rods 23 and the two support frames 24 arranged in a one-to-one correspondence and respectively arranged on both sides of the main rod 21.

[0048] In a preferred embodiment, the support rod 23 is connected at the middle position of the corresponding support frame 24, thereby improving the stability of the connection of the support frame 24, so that the air conditioning panel 200 is more stable when it is hung on the support frame 24.

[0049] In other embodiments, each support frame 24 may also be provided with a plurality of support rods 23. The plurality of support rods 23 may be evenly arranged on both sides of the main rod 21. In this embodiment, providing a plurality of support rods 23 can improve the stability of the connection of the support frame 24. The plurality of support rods 23 may be arranged at intervals, thereby providing a uniform supporting force to the entire support frame 24.

[0050] In some embodiments, the diameter of the support rod 23 can be designed according to specific needs, such as the weight of the air conditioning panel 200. The heavier the air conditioning panel 200, the larger the diameter of the support rod 23; the lighter the air conditioning panel 200, the smaller the diameter of the support rod 23. The design of the diameter of the support rod 23 is very important. If the diameter of the support rod 23 is not designed properly, deformation, bending, or even breakage may occur when the air conditioning panel 200 is hung on the support frame 24, affecting the normal testing of the air conditioning panel 200. However, the diameter of the support rod 23 cannot be designed too large. If the diameter of the support rod 23 is designed too large, it will increase the weight of the mounting device 20, affect the transmission efficiency, and ultimately affect the testing efficiency of the air conditioning panel 200.

[0051] In some embodiments, the included angle between the support rod 23 and the main rod 21 can be designed according to specific requirements. The smaller the included angle between the support rod 23 and the main rod 21, the higher the corresponding support frame 24 will be; the larger the included angle between the support rod 23 and the main rod 21, the lower the corresponding support frame 24 will be. The included angle between the support frame 24 and the main rod 21 can be any value between 30° and 80°, for example, 30°, 40°, 50°, 60°, 70°, 80°, etc.

[0052] See Figure 3 In some embodiments, each support frame 24 includes a frame body 26 and a plurality of protruding rods 25, the frame body 26 being connected to a corresponding support rod 23. The plurality of protruding rods 25 are spaced apart on the frame body 26 and are formed by the frame body 26 protruding obliquely upward, and the air conditioning panel 200 is hung on the protruding rods 25.

[0053] This embodiment improves the stability of the air conditioning panel 200 by designing a protruding rod 25 on the frame 26, and prevents the air conditioning panel 200 from slipping off the mounting bracket 20 during transmission.

[0054] In some embodiments, the frame 26 is elongated or square, and a plurality of protruding rods 25 are arranged at intervals along the extension direction of the frame 26.

[0055] In some embodiments, each support frame 24 includes two protruding rods 25 spaced apart on the frame 26, thereby providing uniform support for the air conditioning panel 200. The two protruding rods 25 are located at the edges of the frame 26. In other embodiments, the positions of the two protruding rods 25 can be selected according to specific needs.

[0056] In other embodiments, each support frame 24 may also include three, four, or five protruding rods 25, with the protruding rods 25 evenly arranged along the extension direction of the frame 26. The number of protruding rods 25 can be determined based on the length of the air conditioning panel 200; the longer the air conditioning panel 200, the more protruding rods 25 are required, and the shorter the air conditioning panel 200, the fewer protruding rods 25 are required.

[0057] In some embodiments, the diameter of the protruding rod 25 can be designed according to specific needs, such as the weight of the air conditioning panel 200. The heavier the air conditioning panel 200, the larger the diameter of the protruding rod 25; the lighter the air conditioning panel 200, the smaller the diameter of the protruding rod 25. The design of the diameter of the protruding rod 25 is very important. If the diameter of the protruding rod 25 is not designed properly, deformation, bending, or even breakage may occur when the air conditioning panel 200 is attached to the protruding rod 25, affecting the normal testing of the air conditioning panel 200. However, the diameter of the protruding rod 25 cannot be designed too large, as this may cause the air conditioning panel 200 to slip off.

[0058] In some embodiments, the frame 26 is square and has two first sides 27 along the conveying direction and two second sides 28 perpendicular to the conveying direction. One second side 28 is connected to the support rod 23, and the other second side 28 has a protruding rod 25. Both first sides 27 are used to hang the air conditioning panel 200. Here, the second side 28 closer to the support rod 23 is connected to the support rod 23, and the second side 28 farther from the support rod 23 has a protruding rod 25. In other embodiments, the shape of the frame 26 can also be designed according to specific needs.

[0059] This embodiment designs the frame 26 as a square, so that the side of the frame 26 can also be used to hang the air conditioning panel 200. Multiple air conditioning panels 200 on the same support component 22 can be inspected, thereby further improving the efficiency of air conditioning panel 200 inspection.

[0060] In a preferred embodiment, the support rod 23 is connected at the middle position of the second side 28, thereby allowing the frame 26 to remain balanced on both sides.

[0061] In some embodiments, the frame 26 is rectangular; in another embodiment, the frame 26 can also be designed to be upright, and the specific design can be made according to the requirements.

[0062] When the frame 26 is designed to be rectangular, its length direction is consistent with the extension direction of the conveying device 10, that is, consistent with the conveying direction. Larger air conditioning panels 200 can be hung along the length direction of the frame 26, and smaller air conditioning panels 200 can be hung along the width direction of the frame 26. Air conditioning panels 200 of appropriate size can be hung according to the size of the frame 26.

[0063] When the frame 26 is designed as a square, the air conditioning panel 200 can be selectively attached to either side of the frame 26.

[0064] In some embodiments, the diameter of the frame 26 can be designed according to specific design requirements. For example, it can be designed to be the same as the diameter of the support frame 24, or it can be different from the diameter of the support frame 24. It can be larger than the diameter of the support frame 24, or it can be smaller than the diameter of the support frame 24.

[0065] Furthermore, the diameter of the frame 26 can be designed according to specific needs, such as the weight of the air conditioning panel 200. The heavier the air conditioning panel 200, the larger the diameter of the frame 26; the lighter the air conditioning panel 200, the smaller the diameter of the frame 26. The design of the diameter of the frame 26 is very important. If the design is unreasonable, the air conditioning panel 200 may deform, bend, or even break when it is hung on the frame 26, affecting the normal testing of the air conditioning panel 200. However, the diameter of the frame 26 cannot be designed too large. If the diameter of the frame 26 is too large, it will increase the weight of the mounting device 20, affect the transmission efficiency, and ultimately affect the testing efficiency of the air conditioning panel 200.

[0066] In some embodiments, each mounting bracket 20 includes a plurality of support components 22, which are spaced apart along the extending direction of the mounting bracket 20. Here, different models of air conditioning panels 200 can be mounted on each support component 22 of the same mounting bracket 20, and support components 22 at the same position on each mounting bracket 20 can mount the same model of air conditioning panels 200. That is, support components 22 at the same height on each mounting bracket 20 can mount the same model of air conditioning panels 200, while support components 22 at different heights can mount different models of air conditioning panels 200.

[0067] This embodiment can distinguish different models of air conditioning panels 200 and hang them at different positions on the mounting bracket 20, thereby enabling the detection and counting of different models of air conditioning panels 200, further improving the detection efficiency of the outdoor unit of the air conditioner.

[0068] In some embodiments, each hanger device 20 includes three sets of support components 22, which are arranged at intervals along the extension direction of the main rod 21, i.e., in the vertical direction, with equal distances between adjacent support components 22. In other embodiments, the distances between adjacent support components 22 may be designed to be unequal.

[0069] In some embodiments, the length of the main rod 21 is related to the number of support components 22. The more support components 22 there are, the longer the main rod 21 is, and the fewer support components 22 there are, the shorter the main rod 21 is.

[0070] In some embodiments, the conveying device 10 is equipped with a chain, and the top of the main rod 21 of each hanger device 20 is connected to the chain, thereby transporting the device along the conveying direction under the drive of the chain. In other embodiments, the conveying device 10 may also employ other structures to move the hanger devices 20.

[0071] Figure 4 yes Figure 1 A schematic structural diagram of the visual inspection device 30 of the air conditioner appearance inspection equipment 100 shown. Figure 4 As shown, in some embodiments, each visual inspection device 30 includes a frame 31 and multiple sets of camera component groups 32. The frame 31 has multiple mounting posts 311 arranged at intervals in the vertical direction, and each mounting post 311 corresponds to a support assembly 22. Each set of camera component groups 32 is mounted on a mounting post 311 and includes at least one camera component. The camera component of each set of camera component groups 32 is used to acquire images of the air conditioning panel 200 hanging on the corresponding support assembly 22. Here, the mounting posts 311 are arranged along the conveying direction.

[0072] This embodiment can be designed with the structure of the bracket device 20 to make the visual inspection device 30 compatible with the bracket device 20. The distance between each visual inspection device 30 and the bracket device 20 needs to ensure that the camera component can clearly and completely capture the air conditioning panel 200.

[0073] In some embodiments, the height of each mounting post 311 is approximately the same as the height of the corresponding support component 22, so that the camera component mounted on the mounting post 311 can clearly and completely capture the air conditioning panel 200 hanging on the corresponding support component 22.

[0074] In some embodiments, the number of mounting posts 311 and support assemblies 22 is three. In other embodiments, the number of mounting posts 311 and support assemblies 22 may also be two, four, five, or six, etc.

[0075] In some embodiments, each group of camera components 32 includes at least one first camera component 321, which is configured to face the corresponding support assembly 22 when each mounting bracket 20 moves to the target position, in order to acquire an image of the air conditioning panel 200 mounted on the front of the support assembly 22. It can be understood that the first camera component 321 is configured to acquire an image of the air conditioning panel 200 mounted on the front of the mounting bracket 20.

[0076] In some embodiments, each camera component group 32 includes a first camera component 321, which is mounted at the center of the mounting post 311. In other embodiments, each camera component group 32 may also include a plurality of first camera components 321, which are spaced apart along the extension direction of the mounting post 311.

[0077] In some embodiments, each group of camera components 32 further includes at least one second camera component 322, which is mounted beside the first camera component 321 and tilted toward the side closer to the first camera component 321. The second camera component 322 is configured to acquire an image of the air conditioning panel 200 side-mounted on the support assembly 22 when each mounting device 20 moves to the target position. It can be understood that the second camera component 322 is configured to acquire an image of the air conditioning panel 200 side-mounted on the mounting device 20, and therefore needs to be tilted.

[0078] In some embodiments, each camera component group 32 includes a second camera component 322, which is mounted on the right side of the first camera component 321 and tilted towards the side closer to the first camera component 321, for acquiring an image of the air conditioning panel 200 hanging on the right side of the support assembly 22. In other embodiments, a second camera component 322 may also be mounted on the left side of the first camera component 321 and tilted towards the side closer to the first camera component 321, for acquiring an image of the air conditioning panel 200 hanging on the left side of the support assembly 22.

[0079] In other embodiments, each camera component group 32 includes two second camera components 322, which are respectively installed on the left and right sides of the first camera component 321, and are both tilted towards the side closer to the first camera component 321. The second camera component 322 installed on the left side is used to acquire an image of the air conditioning panel 200 hanging on the left side of the support assembly 22. The second camera component 322 installed on the right side is used to acquire an image of the air conditioning panel 200 hanging on the right side of the support assembly 22.

[0080] In some embodiments, the first camera component 321 and the second camera component 322 of each camera component group 32 can count all the air conditioning panels 200 detected by them, thereby enabling not only effective identification of different models of air conditioning panels 200, but also counting of different models of air conditioning panels 200.

[0081] In some embodiments, each visual inspection device 30 further includes a sensor 33 mounted on the frame 31 for determining whether the air conditioning panel 200 has reached the target position. Here, the sensor 33 may be a photoelectric sensor.

[0082] In some embodiments, the height difference of the chassis bolts of the air conditioning panel 200 is small, resulting in insufficient detection accuracy. Labeling or other methods are used to enable the camera component to identify different chassis bolt models.

[0083] In some embodiments, the air conditioner appearance inspection equipment 100 further includes an alarm device 40 and an industrial control computer. The alarm device 40 is installed beside one of the vision inspection devices 30 and is used to sound an alarm when the vision inspection device 30 detects that the air conditioner panel 200 is defective. The industrial control computer displays the location of the defective air conditioner panel 200 and displays the defective data, etc. In addition, the three-color alarm of the alarm device 40 will sound an alarm with a red light. If the vision inspection device 30 analyzes and determines that the air conditioner panel 200 meets the requirements, the three-color alarm will display a green light.

[0084] This embodiment provides an online integrated rapid inspection device 100 for the appearance of air conditioner outdoor units. It can classify and count different models of air conditioner panels 200, meeting the counting requirements for various models. When defective products are detected, the device can accurately identify them and feed the information back to the MES or SCADA system, and trigger an alarm via the alarm device 40.

[0085] The air conditioner appearance inspection equipment 100 of this embodiment can control the production cycle to 6 seconds / workpiece, control the equipment failure rate to below 0.5%, and control the missed scan rate to below 0.1%.

[0086] In some embodiments, the working principle of the air conditioner appearance inspection device 100 is as follows:

[0087] When the air conditioner panel 200 reaches the designated detection position, the sensor 33 identifies whether the air conditioner panel 200 has reached the target position and starts the detection timing for the air conditioner panel 200. Simultaneously, multiple sets of camera components 32 begin acquiring images of the air conditioner panel 200. The acquired images are analyzed using image processing methods, compared with images in a standard database, to determine if the air conditioner panel 200 meets the requirements. If the analysis indicates that the air conditioner panel 200 meets the requirements, the three-color alarm displays a green light and proceeds to the next production stage. If the analysis indicates that the air conditioner panel 200 does not meet the requirements, the three-color alarm sounds a red light and displays the problem on the industrial control computer. If a new model of air conditioner panel 200 is introduced, the air conditioner appearance inspection equipment 100 also has a convenient training function, including data acquisition and model deployment.
