Description

Technical Field

[0001] This utility model relates to the field of bowl and basket technology, and specifically to a bowl and basket testing device. Background Technology

[0002] Dish racks are commonly used in dishwashers to hold bowls, plates, and other tableware. Their structure typically includes mesh sidewalls and a bottom. Within the rack, a plastic component connects to the main body, and hooks, casters, and divide the rack into multiple storage areas are installed. During the installation of these plastic components, issues such as omissions, misalignment, or improper installation may occur. Furthermore, the rack may suffer from welding defects, deformation, cracks, and other quality problems. Currently, defect detection in dish racks primarily relies on manual visual inspection, where inspectors visually examine the rack for defects. This method is not only costly and inefficient but also prone to missed or false detections due to fatigue and subjective factors.

[0003] In view of the above-mentioned technical problems, this utility model is proposed in this study. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a bowl basket inspection device, which sets up a fixture, a fixture driving mechanism and an inspection mechanism on a frame. The frame has an inspection area and a loading and unloading area. When inspecting the bowl basket, the fixture carrying the bowl basket is driven by the fixture driving mechanism to move from the loading and unloading area to the inspection area. The inspection mechanism can automatically inspect the bowl basket, which solves the problems of high cost, low efficiency and poor accuracy of manual inspection in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model proposes a bowl basket detection device, comprising:

[0006] Frame 1, which has a detection area 10 and a loading / unloading area 11;

[0007] Fixture 2 is slidably mounted on frame 1 and is used to position and fix the bowl basket;

[0009] The inspection mechanism 4 is mounted on the frame 1 and located in the inspection area 10, and is used to inspect the baskets located in the inspection area 10 for defects.

[0010] A supplementary lighting component 5 is mounted on the frame 1 and faces the detection area 10, and is used to provide supplementary lighting for the bowl basket;

[0011] The detection mechanism 4 includes a detection component 40 and a detection drive component 41. The detection drive component 41 is mounted on the frame 1, and the detection component 40 is mounted on the detection drive component 41 and is driven by the detection drive component 41 to move relative to the basket so as to detect each part of the basket to be detected.

[0015] A beam drive component 412 is disposed on one of the support plates 410 and connected to the beam 411, and is used to drive the beam 411 to reciprocate along the Y-axis direction.

[0016] The detection component 40 is disposed on the crossbeam 411.

[0017] As described above, in a bowl and basket inspection device, the inspection component 40 includes at least one movable visual inspection unit 400 that is movably connected to the crossbeam 411 during inspection and at least one fixed visual inspection unit 4000 that is fixedly connected to the crossbeam 411 during inspection.

The movable visual detection unit 400 is disposed on the slide of the Z-axis linear module 414 and is driven by the Z-axis linear module 414 to reciprocate along the Z-axis direction of the frame 1. The X-axis linear module 413 drives the Z-axis linear module 414 to reciprocate along the X-axis direction of the frame 1, thereby driving the movable visual detection unit 400 to reciprocate along the X-axis direction of the frame 1, thereby detecting different detection parts of the bowl basket.

[0019] In the bowl and basket inspection device described above, there are two fixed visual inspection units 4000, which are respectively located on both ends of the crossbeam 411.

[0020] As described above, the active visual inspection unit 400 and the fixed visual inspection unit 4000 both include a visual camera 401 and an adjustment member 402. The adjustment member 402 is disposed opposite to the crossbeam 411, and the visual camera 401 is disposed on the adjustment member 402, and its shooting angle and / or position are adjusted by the adjustment member 402.

[0021] In the bowl and basket detection device described above, the adjusting member 402 includes:

[0022] The base 4020 is positioned opposite the crossbeam 411;

[0023] Mounting plate 4021 is slidably mounted on base 4020;

[0024] Mounting base 4022 is slidably mounted on mounting plate 4021;

[0025] A rotating base 4023 is rotatably and adjustablely mounted on a mounting base 4022, and the vision camera 401 is mounted on the rotating base 4023.

[0026] As described above, in a bowl and basket inspection device, the fixture driving mechanism 3 includes a linear module 30 disposed on the frame 1 and arranged along the Y-axis direction. The linear module 30 spans the inspection area 10 and the loading and unloading area 11, and the fixture 2 is mounted on the slide of the linear module 30.

[0027] As described above, in a bowl and basket inspection device, the fixture 2 includes a base plate 20 connected to the slide of the linear module 30 and several fixing blocks 21 detachably disposed on the base plate 20. The fixing blocks 21 are formed with positioning grooves 22 that cooperate with the bowl and basket.

[0028] Compared with the prior art, the bowl and basket inspection device of this utility model has the following advantages:

[0029] 1. The bowl basket inspection equipment of this application can inspect the plastic parts of various parts of the bowl basket. Compared with manual inspection, it has higher inspection efficiency and more accurate inspection results.

[0030] 2.

[0048] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0049] like Figure 1-9 As shown, this utility model includes a bowl basket inspection device, comprising a frame 1, a fixture 2, a fixture driving mechanism 3, an inspection mechanism 4, and a supplementary lighting component 5. The frame 1 has an inspection area 10 and a loading / unloading area 11. The fixture 2 is slidably mounted on the frame 1 for positioning and fixing the bowl basket. The fixture driving mechanism 3 is mounted on the frame 1 and connected to the fixture 2, for driving the fixture 2 to move along the Y-axis on the frame 1, so that the bowl basket moves between the loading / unloading area 11 and the inspection area 10. The inspection mechanism 4 is mounted on the frame 1 and located in the inspection area 10 for defect inspection of the bowl basket located in the inspection area 10. The supplementary lighting component 5 is mounted on the frame 1 and faces the inspection area 10 to provide supplementary lighting for the bowl basket. This allows for clearer photographs.

[0050] The detection mechanism 4 includes a detection component 40 and a detection drive component 41. The detection drive component 41 is mounted on the frame 1, and the detection component 40 is mounted on the detection drive component 41 and is driven by the detection drive component 41 to move relative to the basket so as to detect each part of the basket to be detected.

[0051] The bowl basket inspection device of this application is mainly used to monitor whether there are any missing or misaligned plastic parts 6 in the bowl basket. In this embodiment, the inspection area 10 is located in the middle of the frame 1, and the unloading area 11 is located on one side of the inspection area 10 of the frame 1, which facilitates loading and unloading by workers or machinery. When inspecting the bowl basket, workers or machinery fix the bowl basket on the fixture 2. Then, the fixture drive mechanism 3 drives the fixture 2 to move to the inspection area 10, and the inspection drive component 41 drives the inspection component 40 to move relative to the bowl basket to inspect the plastic parts 6 in various parts of the bowl basket. Compared with manual inspection, the inspection efficiency is higher and the inspection results are more accurate.

[0052] like Figures 1 to 5As shown, as a further embodiment, the detection drive assembly 41 includes a pair of support plates 410 spaced apart on the frame 1 and extending along the Y-axis, and a crossbeam 411 mounted on the two support plates 410. The two ends of the crossbeam 411 are slidably engaged with the corresponding support plates 410. The detection assembly 40 is mounted on the crossbeam 411. The detection drive assembly 41 also includes a crossbeam drive member 412, which is mounted on one of the support plates 410 and connected to the crossbeam 411, for driving the crossbeam 411 to reciprocate along the Y-axis. The detection assembly 40 is mounted on the crossbeam 411. It should be noted that the support plates 410 are connected to the frame 1 via several support rods 4100, and the crossbeam 411 is mounted between the two support plates 410. Since the detection assembly 40 is mounted on the crossbeam 411, the detection assembly 40 is positioned relatively above the basket.

[0053] It should be noted that the crossbeam drive component 412 is a lead screw module, which is a conventional technology in the field and will not be described in detail here. By driving the crossbeam 411 to move through the lead screw module, the crossbeam 411 can be operated more precisely.

[0054] like Figures 1 to 5 As shown, as a further embodiment, the detection assembly 40 includes at least one movable visual detection unit 400 that is movably connected to the crossbeam 411 during detection and at least one fixed visual detection unit 4000 that is fixedly connected to the crossbeam 411 during detection. In this embodiment, two fixed visual detection units 4000 are provided, respectively located at both ends of the crossbeam 411. A fixing plate 4110 extends outward from one end of the crossbeam 411, and the fixed visual detection units 4000 are located on the fixing plate 4110. By providing two fixed visual detection units 4000, the plastic parts 6 on both sides of the basket can be detected simultaneously, thereby improving detection efficiency. The movable visual detection unit 400 is movable relative to the crossbeam 411, and can flexibly reach the middle position of the basket, complex grooves, and other parts that need to be detected, providing greater flexibility.

[0055] Specifically, the detection drive assembly 41 further includes an X-axis linear module 413 disposed on the crossbeam 411 and a Z-axis linear module 414 disposed on the slide of the X-axis linear module 413. The active vision detection unit 400 is disposed on the slide of the Z-axis linear module 414 and is driven by the Z-axis linear module 414 to reciprocate along the Z-axis direction of the frame 1. The X-axis linear module 413 drives the Z-axis linear module 414 to reciprocate along the X-axis direction of the frame 1, thereby driving the active vision detection unit 400 to reciprocate along the X-axis direction of the frame 1, thereby detecting different detection parts of the basket.

[0056] like Figure 5 Figure 6 As shown, as a further embodiment, both the active visual detection unit 400 and the fixed visual detection unit 4000 include a visual camera 401 and an adjustment member 402. The adjustment member 402 is disposed opposite to the crossbeam 411. The visual camera 401 is disposed on the adjustment member 402, and its shooting angle and / or position are adjusted by the adjustment member 402. The adjustment member 402 includes a base 4020, a mounting plate 4021, a mounting seat 4022, and a rotating seat 4023. The base 4020 is disposed opposite to the crossbeam 411. In this embodiment, the base 4020 is disposed on the fixed plate 4110, the mounting plate 4021 is slidably disposed on the base 4020, the mounting seat 4022 is slidably disposed on the mounting plate 4021, and the rotating seat 4023 is rotatably and adjustablely disposed on the mounting seat 4022. The visual camera 401 is disposed on the rotating seat 4023. In this embodiment, the adjustment component 402 facilitates the adjustment of the position and angle of the visual camera 401 by the staff.

[0057] like Figures 1 to 4 As shown, as a further embodiment, the fixture driving mechanism 3 includes a linear module 30 disposed on the frame 1 and arranged along the Y-axis direction. The linear module 30 spans the detection area 10 and the loading and unloading area 11, and the fixture 2 is mounted on the slide of the linear module 30.

[0058] The fixture 2 includes a base plate 20 connected to the slide of the linear module 30 and several fixing blocks 21 detachably disposed on the base plate 20. The fixing blocks 21 are formed with positioning grooves 22 that cooperate with the basket.

[0059] In this embodiment, the linear module 30 can also be replaced by a cylinder to drive the fixture 2 to move, which can reduce costs. In this application, the fixing block 21 is detachably set, such as being connected to the base plate 20 by screw locking. When changing different bowl baskets, only different fixing blocks 21 need to be replaced, without replacing the entire fixture 2. It should also be noted that when the bowl basket is placed on the fixing block 21, the support frame or base of the bowl basket can be embedded into the positioning groove 22.

[0060] like Figures 1 to 9 As shown, this utility model also provides a method for detecting defects in a bowl basket, including using the bowl basket detection equipment described above. The detection method includes the following steps:

[0061] S1. Loading: The staff or robotic arm fixes the basket to be inspected onto the fixture 2 located in the loading and unloading area 11, so that the supporting legs of the basket fall into the positioning groove 22, thus completing the positioning and fixing.

[0062] S2. Transfer: The fixture 2 is moved along the Y-axis by the fixture driving mechanism 3 to transfer the bowl basket from the loading and unloading area 11 to the preset detection position of the detection area 10.

[0063] S3. Detection: The detection drive component 41 drives the detection component 40 to move relative to the bowl basket in order to acquire an image of the part of the bowl basket to be detected.

[0064] S4. Analysis: The image acquired by the detection component 40 is compared with a preset standard graphic to determine whether the bowl basket has a defect. A defect report is generated for bowl baskets with defects. The defect report includes the defect type, the severity of the defect, and the specific location information of the defect on the bowl basket.

[0065] In this step, the image is compared with a standard image, allowing for image preprocessing, enhancement, and contrast adjustment. The processed image is then compared with a pre-entered database of "standard images" of qualified bowl baskets. The comparison includes, but is not limited to: whether plastic part 6 is missing, whether it is misaligned, whether the bowl basket is deformed, the integrity of the mesh, and the presence of burrs or cracks. This application primarily addresses the issues of missing and misaligned plastic part 6. Finally, based on the comparison results, the system automatically determines whether the bowl basket is qualified. For non-qualified products, the system automatically generates a detailed defect report, clearly indicating the type of defect, such as whether plastic part 6 is missing or misaligned, and the precise location of the defect on the bowl basket, to facilitate subsequent processing by staff.

[0066] S5. Unloading: Based on the judgment result, the fixture drive mechanism 3 moves the basket back to the loading and unloading area 11 for unloading. The operator or robot will place the qualified products in the qualified product transfer area according to the system's judgment, and sort the unqualified products to the rework or scrap area to complete a complete inspection cycle.

[0067] As a further embodiment, the detection drive assembly 41 includes a pair of support plates 410 spaced apart on the frame 1 and extending along the Y-axis, and a crossbeam 411 mounted on the two support plates 410. The two ends of the crossbeam 411 are slidably engaged with corresponding support plates 410. The detection assembly 40 is mounted on the crossbeam 411. The detection drive assembly 41 also includes a crossbeam drive member 412, which is mounted on one of the support plates 410 and connected to the crossbeam 411, for driving the crossbeam 411 to reciprocate along the Y-axis. The detection assembly 40 is mounted on the crossbeam 411. The detection assembly 40 includes at least one movable visual detection unit 400 that is movably connected to the crossbeam 411 during detection and at least one fixed visual detection unit 4000 that is fixedly connected to the crossbeam 411 during detection.

[0068] Step S3 also includes:

[0069] S31. Fixed Inspection Section: Fixed vision inspection units 4000 synchronously acquire images of the regular inspection areas of the basket. Specifically, the crossbeam drive unit 412 drives the crossbeam 411 to move slowly along the Y-axis, and the two fixed vision inspection units 4000 fixedly installed at both ends of the crossbeam 411 are opened simultaneously, taking pictures of the plastic parts 6 on both sides of the basket during the movement.

[0070] S32. Active Detection Section: The active vision detection unit 400 acquires images of complex areas to be inspected in the basket. The active detection section and the fixed detection section can operate simultaneously. The active vision detection unit 400 begins operation. The control system runs according to the preset detection path. The crossbeam drive unit 412 drives the crossbeam 411 to move along the Y-axis, thereby driving the active vision detection unit 400 to move along the Y-axis. The X-axis linear module 413 and the Z-axis linear module 414 can then drive the active vision detection unit 400 to move along the X-axis and Z-axis. Therefore, the active vision detection unit 400 can move along the X-axis, Y-axis, and Z-axis, thus moving to various key areas inside the basket for imaging. In this step, by combining the active vision detection unit 400 and the fixed vision detection unit 4000, the fixed vision detection unit 4000 can quickly capture images of conventional locations, while the active vision detection unit 4000 can capture images of complex locations, thereby improving detection efficiency. It should also be noted that steps S31 and S32 can be performed partially synchronously or sequentially.
