Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing, and in particular relates to a visual inspection device for cross-flow blades. Background Technology

[0002] Cross-flow fan blades are an important component of air conditioning indoor units. The geometric parameters and blade distribution of the cross-flow fan blades have a significant impact on the ventilation characteristics of the fan. Therefore, after the cross-flow fan blades are manufactured, their appearance needs to be visually inspected to ensure that they meet the required performance.

[0003] Currently, when visually inspecting cross-flow blades, cameras are used to directly capture images of the blades. However, the background of the images obtained by this method is often quite complex, which can interfere with subsequent image recognition and make it difficult to accurately detect the aggregate parameters of the cross-flow blades. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a visual inspection device for cross-flow blades, which can solve the above-mentioned technical problems.

[0005] This utility model embodiment is implemented as follows: a visual inspection device for cross-flow blades is provided, the visual inspection device for cross-flow blades comprising:

[0006] Equipment body;

[0007] A conveyor belt, installed on the main body of the equipment, is used to transport the cross-flow blades;

[0008] The gripping device, installed on the equipment body, is used to grip the cross-flow blades on the conveyor belt;

[0009] A camera, mounted on the device itself, is used to capture images of the cross-flow blades;

[0010] The background panel is mounted on a mover set on the main body of the equipment. When the gripping device picks up the cross-flow blades on the conveyor belt and positions the cross-flow blades directly in front of the camera, the mover moves the background panel directly below the camera so that the cross-flow blades are between the camera lens and the background panel, allowing the camera to capture images of the cross-flow blades with the background panel as the background.

[0011] Preferably, the gripping device is mounted on a flipping mechanism, which includes:

[0012] The flip motor is mounted on the main body of the equipment.

[0013] Two first supports are respectively set on the two long sides of the conveyor belt;

[0014] The rotating shaft is mounted on two first supports, spanning the conveyor belt. One end of the rotating shaft is connected to the output end of the rotating motor. The gripping device is fixed on the rotating shaft. After the gripping device grips the cross-flow blades, the rotating motor drives the rotating shaft to rotate, thereby rotating the cross-flow blades on the gripping device.

[0015] Preferably, the gripping device includes:

[0016] Dual-axis motor, fixed on the tilting shaft;

[0017] Two clamping parts are respectively installed on the two telescopic shafts of the dual-axis motor. The dual-axis motor retracts the two telescopic shafts at the same time to bring the two clamping parts closer together to clamp the cross-flow blades. The dual-axis motor extends the two telescopic shafts at the same time to place the clamped cross-flow blades.

[0018] Preferably, a blocking member is provided on the conveyor belt, and a first recessed portion adapted to the shape of the cross-flow blade is provided on the blocking member. When the cross-flow blade is conveyed by the conveyor belt to the first recessed portion of the blocking member, the blocking member prevents the cross-flow blade from continuing to move forward, and the first recessed portion limits the cross-flow blade to prevent the cross-flow blade from lateral movement on the conveyor belt.

[0019] Preferably, each clamping part has a second recess that is adapted to the shape of the cross-flow blade. When the cross-flow blade is conveyed to the first recess, the dual-axis motor simultaneously retracts the two telescopic shafts, bringing the two clamping parts closer together so that the second recess fits perfectly with the cross-flow blade, thereby achieving stable clamping of the cross-flow blade.

[0020] Preferably, two second supports are provided on the two long sides of the conveyor belt, and a crossbeam is erected between the two second supports. The camera is mounted on the crossbeam and faces downward toward the conveyor belt.

[0021] Preferably, the mover is a telescopic cylinder, the side edge of the background plate is fixed to the output end of the mover, and the plane where the background plate is located is parallel to the plane where the conveyor belt is located; when the flipping mechanism flips the gripping device, the cross-flow blade gripped by the gripping device faces the camera, the mover extends the output end, so that the background plate is located directly below the cross-flow blade, thereby enabling the camera to capture images of the cross-flow blade with the background plate as the background. After the acquisition is completed, the mover retracts the output end, so that the background plate is moved away from under the cross-flow blade, so that the gripping device can place the cross-flow blade back on the conveyor belt, so that the cross-flow blade can continue to be conveyed.

[0022] The cross-flow blade visual inspection device provided in this embodiment includes: a device body; a conveyor belt disposed on the device body for conveying cross-flow blades; a gripping device disposed on the device body for gripping the cross-flow blades on the conveyor belt; a camera disposed on the device body for image acquisition of the cross-flow blades; and a background plate mounted on a mover disposed on the device body. When the gripping device picks up the cross-flow blades from the conveyor belt and positions the cross-flow blades directly facing the camera, the mover moves the background plate directly below the camera so that the cross-flow blades are positioned between the camera lens and the background plate, allowing the camera to acquire images of the cross-flow blades against the background plate. In this application, the background plate can be extended when acquiring images of the cross-flow blades to avoid interference from cluttered backgrounds, thereby reducing the influencing factors on subsequent image analysis and improving the accuracy of visual inspection of the cross-flow blades. Furthermore, after image acquisition is completed, the background plate can be retracted to avoid obstructing the conveyance of the cross-flow blades. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] like Figure 1 As shown, a visual inspection device for a cross-flow blade is provided in an embodiment of this utility model. The visual inspection device for the cross-flow blade includes:

[0031] Equipment body 1;

[0032] Conveyor belt 2, installed on the equipment body 1, is used to transport the cross-flow blades;

[0033] The gripping device 3 is installed on the equipment body 1 and is used to grip the cross-flow blades on the conveyor belt 2;

[0034] Camera 4, mounted on the device body 1, is used to acquire images of the cross-flow blades;

[0035] Background plate 5 is mounted on mover 6 on the device body 1. When gripping device 3 picks up the cross-flow blade on conveyor belt 2 and positions the cross-flow blade directly in front of camera 4, mover 6 moves background plate 5 directly below camera 4 so that the cross-flow blade is between the lens of camera 4 and background plate 5, so that camera 4 can capture images of cross-flow blade with background plate 5 as background.

[0036] In this embodiment, the background plate 5 can be set as a square background plate 5, and the color of the background plate 5 can be set as black. When it is necessary to capture images of the cross-flow blades and the background plate 5 is moved into place, the distance between the background plate 5 and the camera 4 allows the size of the background plate 5 to cover the entire field of view of the camera 4, so that the background of the images captured by the camera 4 is black, so as to highlight the cross-flow blades in the image.

[0037] In this application, a background plate 5 can be extended when acquiring images of the cross-flow blade to avoid interference from cluttered backgrounds, thereby reducing the influencing factors on subsequent image analysis and improving the accuracy of visual inspection of the cross-flow blade. Furthermore, after image acquisition is completed, the background plate 5 can be retracted to avoid obstructing the transport of the cross-flow blade.

[0038] In a preferred embodiment, the gripping device 3 is mounted on the flipping mechanism 7, which includes:

[0039] A flip motor 71 is mounted on the main body 1 of the device.

[0040] Two first supports 72 are respectively set on the two long sides of the conveyor belt 2;

[0041] The flip shaft 73 is mounted on two first supports 72, so that the flip shaft 73 spans the conveyor belt 2, and one end of the flip shaft 73 is connected to the output end of the flip motor 71. The gripping device 3 is fixed on the flip shaft 73. After the gripping device 3 grips the cross-flow blade, the flip motor 71 drives the flip shaft 73 to rotate, thereby flipping the cross-flow blade on the gripping device 3.

[0042] The gripping device 3 includes:

[0043] A dual-axis motor 31 is fixed on the tilting shaft 73;

[0044] Two clamping parts 32 are respectively mounted on the two telescopic shafts of the dual-axis motor 31. The dual-axis motor 31 simultaneously retracts the two telescopic shafts, bringing the two clamping parts 32 closer together to clamp the cross-flow blades. The dual-axis motor 31 simultaneously extends the two telescopic shafts to hold the clamped cross-flow blades. 8

[0045] In this embodiment, two sets of flipping mechanisms 7 are provided on the device body 1. Each set of flipping mechanisms 7 is provided with a gripping device 3. One set of flipping mechanisms 7 and gripping device 3 grips and flips the cross-flow blades on the conveyor belt 2 (and captures images of the cross-flow blades during the flipping process) and then places them on the conveyor belt 2. The other set of flipping mechanisms 7 and gripping device 3 then flips the cross-flow blades placed on the conveyor belt 2 again and places them on the conveyor belt 2, so that the cross-flow blades are conveyed on the conveyor belt 2 in their initial placement state.

[0046] In a preferred embodiment, a blocking member 21 is provided on the conveyor belt 2. The blocking member 21 has a first recess that is adapted to the shape of the cross-flow blade. When the cross-flow blade is conveyed by the conveyor belt 2 to the first recess of the blocking member 21, the blocking member 21 prevents the cross-flow blade from continuing to move forward, and the first recess limits the cross-flow blade to prevent the cross-flow blade from lateral movement on the conveyor belt 2.

[0047] Each clamping part 32 has a second recess that is adapted to the shape of the cross-flow blade. When the cross-flow blade is conveyed to the first recess, the dual-axis motor 31 simultaneously retracts the two telescopic shafts, bringing the two clamping parts 32 closer together, so that the second recess fits into the cross-flow blade, thereby achieving stable clamping of the cross-flow blade.

[0048] In this embodiment, the outer edge contour of the cross-flow blade is circular. Both the first and second recesses are set as arc-shaped recesses with the same curvature as the circle. This allows the cross-flow blade to be stably confined in the first recess when it is conveyed to the first recess, so that the gripping part 32 of the gripping device 3 can accurately grip the cross-flow blade. Furthermore, since the shape of the second recess is also adapted to the contour shape of the cross-flow blade, the gripping part 32 can stably grip the cross-flow blade, thereby preventing the cross-flow blade from detaching during flipping and image acquisition.

[0049] In a preferred embodiment, two second supports 22 are provided on the two long sides of the conveyor belt 2, and a crossbeam 23 is erected between the two second supports 22. The camera 4 is mounted on the crossbeam 23 and faces downward toward the conveyor belt 2.

[0050] The mover 6 is a telescopic cylinder. The side edge of the background plate 5 is fixed to the output end of the mover 6, and the plane on which the background plate 5 is located is parallel to the plane on which the conveyor belt 2 is located. When the flipping mechanism 7 flips the gripping device 3, the cross-flow blade gripped by the gripping device 3 faces the camera 4. The mover 6 extends its output end, so that the background plate 5 is located directly below the cross-flow blade, thereby enabling the camera 4 to capture images of the cross-flow blade with the background plate 5 as the background. After the acquisition is completed, the mover 6 retracts its output end, so that the background plate 5 is moved away from under the cross-flow blade, allowing the gripping device 3 to place the cross-flow blade back on the conveyor belt 2, so that the cross-flow blade can continue to be conveyed.

[0051] In this embodiment, when the cross-flow blade is flipped into place and the background plate 5 is moved directly below the cross-flow blade, the camera 4, the cross-flow blade, and the background plate 5 are on the same vertical axis, so that the background plate 5 can appear in the field of view of the camera 4. The camera 4 is mounted on the crossbeam 23 through a lifting mechanism. Before use, the user can adjust the height of the camera 4 through the lifting mechanism so that when the camera 4, the cross-flow blade, and the background plate 5 are on the same vertical axis, the background plate 5 can fill the entire field of view of the camera 4, thereby eliminating the interference of other cluttered backgrounds on the image.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
