A first sensor 8 is provided at the station to be inspected, and the first sensor 8 is used to detect that the air-conditioning outdoor unit 2 enters the station to be inspected. A second sensor 9 is provided between the station to be inspected and the inspection station, and the second sensor 9 is used to detect that the air-conditioning outdoor unit 2 leaves the station to be inspected. The first blocker 7, the first sensor 8, and the second sensor 9 are provided to control the movement of the air-conditioning outdoor unit 2, so that the air-conditioning outdoor unit 2 moves from the station to be inspected to the inspection station after the inspection is completed.

[0037] Further, a third sensor 10 is provided on one side of the detection station, and the third sensor 10 is used to detect the air conditioner outdoor unit 2 placed on the detection station. A second blocker 11 is provided at one end of the detection station, and the second blocker 11 moves in a vertical direction on the assembly line 1 to control the movement of the air conditioner outdoor unit 2. The detection component includes a measuring grating, which is provided on opposite sides of the assembly line 1, and the measuring grating is used to measure the length and height of the air conditioner outdoor unit 2. The size parameters of the air conditioner outdoor unit 2 detected by the measuring grating are used to control the shooting of the image acquisition component 6.

[0038] Furthermore, the image acquisition component 6 includes a robot 4 and a front camera module. The robot 4 is provided with a camera for taking top and side images of the air-conditioning outdoor unit 2. The front camera module is arranged on one side of the inspection station of the assembly line 1 for taking a front image of the air-conditioning outdoor unit 2.

[0039] Furthermore, the detection component and the image acquisition component 6 are respectively connected to the controller 5, and the controller 5 controls the detection component to detect the size parameters of the air-conditioning outdoor unit 2, and also controls the image acquisition component 6 to capture the top, side and front images of the air-conditioning outdoor unit 2.

[0040] like Figure 3 As shown, the present invention also provides an air conditioner outdoor unit label detection method, the air conditioner outdoor unit 2 enters the detection station, the detection component measures the size parameters of the air conditioner outdoor unit 2, and the robot 4 moves to a specific position according to the size parameters to take images.

[0041] Specifically, when the air-conditioning outdoor unit 2 enters the inspection station, the first sensor 8 controls the first blocker 7 to rise after receiving the signal, sends a code scanning signal to start the identification component to scan the code, and controls the first blocker 7 to descend after the identification component reaches the specified position, and the robot 4 obtains the height of the air-conditioning outdoor unit 2. After the air-conditioning outdoor unit 2 enters the inspection station, the third sensor 10 controls the second blocker 11 to rise after receiving the signal, triggering the front module camera to take the front image of the air-conditioning outdoor unit 2 and the image acquisition component 6 to take the side and top images of the air-conditioning outdoor unit 2.

[0042] The air conditioner outdoor unit label detection method provided by the present invention is described in detail below through specific embodiments.

[0043] The assembly line 1 and the front camera module are controlled by the controller 5, the camera is controlled by the visual system, the controller 5 and the robot 4 communicate via Ethernet, the robot 4 communicates via Ethernet with the host computer, and the two pairs of measuring gratings communicate via MODBUS with the controller 5. One pair of measuring gratings is used to measure the height of the external unit, and the other pair is used to measure the length of the external unit. Each pair of measuring gratings is configured with different addresses using software before being connected to the controller 5, and then the two pairs of gratings are connected to the same RS485 module of the controller 5 for networking.

[0044] When there is no air conditioner outdoor unit 2 at the inspection station, the outdoor unit flowing in from the assembly line 1 enters the station to be inspected, the first sensor 8 receives the signal, the first blocker 7 is lifted, the controller 5 sends a code scanning signal to the robot 4 to move to the specified position to trigger the camera to scan the code, and the robot 4 feeds back the in-position signal to the controller 5 after it moves to the position, and then the first blocker 7 drops, the controller 5 sends a specified command to the grating for measuring the height to measure the height of the outdoor unit, and then the measuring grating feeds back the data to the controller 5, the controller 5 processes the feedback data to obtain the height of the outdoor unit, and the camera feeds back the successful code scanning signal to the robot 4 after the code scanning is successful, and then the controller 5 sends the height value of the outdoor unit to the robot 4 again, and the robot 4 assigns this height value to the Z axis of the robot 4, and then the robot 4 can move to the height corresponding to the top surface of the outdoor unit according to different height values. The height of the top surface of each model from the camera on the robot 4 fixture is the same. After the outdoor unit enters the detection area, the third sensor 10 detects that it is in place, the second blocker 11 is lifted, and the correction mechanism clamps the outdoor unit to trigger the front module camera to take a photo to detect the front of the outdoor unit and trigger the robot 4 camera to take a photo to detect the top surface of the outdoor unit. At the same time, the controller 5 sends a command to the length measuring grating to measure the length of the outdoor unit. After the controller 5 obtains the length of the outdoor unit, it sends the length data to the robot 4. The robot 4 assigns this length value to the Y axis of the robot 4. Then, after the top surface photo is taken, the robot 4 moves to the side of the outdoor unit according to the length of the outdoor unit received to trigger the camera to take a photo. The length of the side of each model from the camera on the robot 4 fixture is the same. After the robot 4 takes the photo, it returns to the starting point. The upper computer sends the photo result to the robot 4. If the photo result is qualified, the second blocker 11 drops and waits for the next air-conditioning outdoor unit 2. If the photo result is unqualified, the assembly line 1 will alarm and stop the line, waiting for manual confirmation before passing and flowing into the next station.

[0045] The air conditioner outdoor unit label detection method and device provided by the present invention replaces the manual detection of whether there are nameplates, trademarks, color strips, grilles and screws on the surface of the air conditioner outdoor unit 2, and realizes fully automated detection, which can be compatible with the detection of outdoor units of various sizes and accurately locate the detection. Two pairs of measuring gratings are used to measure the length and height of the air conditioner outdoor unit 2 respectively. The robot 4 can detect outdoor units of various sizes by obtaining the length and height data. The robot 4 will automatically adjust the movement point according to the data, and always maintain the best shooting position for each air conditioner outdoor unit 2, so that the detection accuracy is higher.

[0046] In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
