Description

Technical Field

[0001] This utility model relates to testing equipment, and more particularly to a non-destructive full-surface appearance testing equipment for fruits and vegetables. Background Technology

[0002] Fruits and vegetables typically undergo multiple inspections from harvesting to packaging to remove those with quality issues. Quality is usually assessed through the appearance of the fruit or vegetable's skin, such as checking for damage. However, in current transport line structures, fruits and vegetables are often laid out randomly or arranged in single rows on the conveyor belt. Cameras can only capture the "top" or "upward-facing" surface of the produce, while the bottom surface in contact with the conveyor belt and the sides obscured by neighboring fruits and vegetables are completely outside the camera's field of vision. Therefore, improvements are needed. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies, such as poor surface inspection of fruits and vegetables, by providing a new non-destructive full-surface appearance inspection device for fruits and vegetables.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A non-destructive full-surface appearance inspection device for fruits and vegetables includes a fruit cup synchronous conveyor line, a suction device, and a fruit and vegetable surface inspection device. The fruit cup synchronous conveyor line is provided on both sides of the suction device, and the fruit and vegetable surface inspection device is provided on both sides of the fruit cup synchronous conveyor line to form an inspection area. When the suction device picks up the fruit and vegetables from the fruit cup synchronous conveyor line and moves them to the inspection area, the fruit and vegetable surface inspection device can inspect the surface of the fruit and vegetables.

[0005] This application uses a suction device to first suck up fruits and vegetables, and then uses a fruit and vegetable surface detection device to detect the surface of the fruits and vegetables. Since the fruits and vegetables are sucked up and raised by the suction device, the fruit and vegetable surface detection device can detect the surface of the fruits and vegetables without blind spots.

[0006] Preferably, the above-described non-destructive full-surface appearance inspection equipment for fruits and vegetables includes a workbench and a surface inspection camera and a bottom inspection camera installed on the workbench. The surface inspection camera is installed horizontally on the workbench, and the bottom inspection camera is installed at an angle on the workbench.

[0007] Preferably, the above-described non-destructive full-surface appearance inspection equipment for fruits and vegetables further includes a light shield, which is disposed at the upper end of the workbench and encloses the surface inspection camera and the bottom inspection camera.

[0008] Preferably, in the above-described non-destructive full-surface appearance inspection equipment for fruits and vegetables, the suction device includes a working frame and a gripping assembly. The gripping assembly includes a drive rod and a suction cup. The suction cup is movably disposed at the lower end of the drive rod. The working frame is provided with a guide rail assembly. The drive rod is mounted on the guide rail assembly. The drive rod can drive the suction cup to move horizontally and vertically.

[0009] As a preferred embodiment, the guide rail assembly of the above-described non-destructive full-surface appearance inspection equipment for fruits and vegetables includes a horizontal guide rail and an undulating guide rail. The drive rod is equipped with a first pulley group, which cooperates with the horizontal guide rail to control the drive rod to move in the horizontal direction; The drive rod is also equipped with a second pulley group, which cooperates with the undulating guide rail to control the drive rod to move up and down.

[0010] Preferably, in the above-described non-destructive full-surface appearance inspection device for fruits and vegetables, a friction plate is provided above the work frame near the fruit and vegetable surface inspection device, and a friction block is provided at the upper end of the suction cup. When the friction block of the suction cup contacts the friction plate, the friction block will drive the suction cup to rotate.

[0011] Preferably, in the above-mentioned non-destructive full-surface appearance inspection equipment for fruits and vegetables, infrared detection devices are provided at both the inlet and outlet of the synchronous conveyor line for fruit cups.

[0012] The present invention has the following advantages through the above structural improvements: Compared with the current fruit and vegetable testing methods, this application has the advantage of comprehensive and blind-spot-free testing. The fruit and vegetable is first grasped by the suction device, and after the suction device brings the fruit and vegetable into the testing area, the fruit and vegetable surface testing device can test the surface of the fruit and vegetable. Since the fruit and vegetable is lifted by the suction device, the fruit and vegetable surface testing device can achieve comprehensive and blind-spot-free testing of the surface of the fruit and vegetable.

[0015] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described in detail with reference to specific embodiments, but these are not intended to limit the present invention: Example

[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a non-destructive full-surface appearance inspection device for fruits and vegetables includes a fruit cup synchronous conveyor line 1, a suction device 2, and a fruit and vegetable surface inspection device 3. The fruit cup synchronous conveyor line 1 is provided on both sides of the suction device 2, and the fruit and vegetable surface inspection device 3 is provided on both sides of the fruit cup synchronous conveyor line 1 to form an inspection area 4. When the suction device 2 picks up the fruits and vegetables from the fruit cup synchronous conveyor line 1 and moves them into the inspection area 4, the fruit and vegetable surface inspection device 3 can inspect the surface of the fruits and vegetables.

[0017] Preferably, the fruit and vegetable surface detection device 3 includes a workbench 31 and a surface detection camera 32 and a bottom detection camera 33 installed on the workbench 31. The surface detection camera 32 is horizontally installed on the workbench 31, and the bottom detection camera 33 is inclinedly installed on the workbench 31.

[0018] Specifically, the surface detection camera 32 and the bottom detection camera 33 work together to take pictures of the surface of fruits and vegetables from all angles without blind spots.

[0019] Preferably, the fruit and vegetable surface detection device 3 further includes a light shield 34, which is disposed on the upper end of the workbench 31 and encloses the surface detection camera 32 and the bottom detection camera 33.

[0020] Furthermore, the use of lens hood 34 can effectively prevent the influence of stray light, thereby effectively improving the image quality of the shot.

[0021] Preferably, the suction device 2 includes a work frame 21 and a gripping assembly 22. The gripping assembly 22 includes a drive rod 221 and a suction cup 222. The suction cup 222 is movably disposed at the lower end of the drive rod 221. The work frame 21 is provided with a guide rail assembly 211. The drive rod 221 is mounted on the guide rail assembly 211. The drive rod 221 can drive the suction cup 222 to move horizontally and vertically.

[0022] Specifically, the drive rod 221 moves horizontally and vertically along the guide rail assembly 211, thereby driving the suction cup 222 to pick up the fruits and vegetables on the fruit cup synchronous conveyor line 1 and move it to the detection area 4 for detection.

[0023] Preferably, the guide rail assembly 211 includes a horizontal guide rail 2111 and an undulating guide rail 2112; The drive rod 221 is provided with a first pulley group 2211, which cooperates with the horizontal guide rail 2111 to control the drive rod 221 to move in the horizontal direction; The drive rod 221 is also provided with a second pulley group 2212, which cooperates with the undulating guide rail 2112 to control the drive rod 221 to move up and down.

[0024] Furthermore, by cooperating with the first pulley group 2211 and the horizontal guide rail 2111, the drive rod 221 can be controlled to move horizontally, and then by cooperating with the second pulley group 2212 and the undulating guide rail 2112, the drive rod 221 can be controlled to move up and down.

[0025] Preferably, the work frame 21 is provided with a friction plate 212 above the fruit and vegetable surface detection device 3, and the upper end of the suction cup 222 is provided with a friction block 2221. When the friction block 2221 of the suction cup 222 comes into contact with the friction plate 212, the friction block 2221 will drive the suction cup 222 to rotate.

[0026] Furthermore, when the friction block 2221 of the suction cup 222 comes into contact with the friction plate 212, the friction block 2221 will drive the suction cup 222 to rotate due to the presence of friction, thereby causing the suction cup 222 to drive the fruits and vegetables to rotate synchronously, thus making the fruit and vegetable surface detection device 3 more accurate in detection.

[0027] Preferably, infrared detection devices 11 are provided at both the inlet and outlet of the fruit cup synchronous conveyor line 1.

[0028] Furthermore, the infrared detection device 11 can detect whether there are fruits and vegetables on the fruit cups when they enter the detection area 4 and leave the detection area 4 on the fruit cup synchronous conveyor line 1.

[0029] In this embodiment, when in use, the fruit cups of the synchronous fruit cup conveyor line 1 are first transported in with the fruits and vegetables. At this time, the infrared detection device 11 will detect whether there are fruits and vegetables on the fruit cups. When the presence of fruits and vegetables is detected, the drive rod 221 will drive the suction cup 222 to pick up the fruits and vegetables along the undulating guide rail 2112. Then, the drive rod 221 will drive the suction cup 222 to move to the detection area 4 along the horizontal guide rail 2111. At this time, the friction block 2221 on the suction cup 222 will contact and rub against the friction plate 212 on the work frame 21, so that the suction cup 222 will rotate. When it enters the detection area 4, the surface detection camera 32 and the bottom detection camera 33 of the fruit and vegetable surface detection device 3 will take pictures of the surface of the fruits and vegetables. Since the suction cup 222 is rotating, the surface detection camera 32 and the bottom detection camera 33 can achieve all-round detection of the fruits and vegetables on the suction cup 222 without blind spots. After the fruit and vegetable inspection is completed, the drive rod 221 drives the suction cup 222 to put the fruit and vegetables back onto the fruit cup of the fruit cup synchronous conveyor line 1. Then the infrared detection device 11 will detect whether the fruit and vegetables are placed in place. Finally, the fruit cup synchronous conveyor line 1 will transport the fruit and vegetables to the next process.

[0030] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
