This structural design, combined with built-in or external control and display components, enables automatic appearance inspection of the developing roller surface. It is particularly suitable for continuous and batch inspection processes, overcoming visual fatigue caused by continuous manual operation and ensuring the stability of developing roller quality. The following section will further elaborate on this design. Figures 1 to 12 The appearance inspection device for the developing roller is described in detail below.

[0051] In one embodiment of this application, a developing roller appearance inspection device 100 is as follows: Figure 1 and Figure 2 As shown, it includes a feeding assembly 600, a defect detection assembly 200, a light leakage detection assembly 300, a discharging assembly 700, and a frame 900. As an example, the feeding assembly 600 is used for feeding, the defect detection assembly 200 is used for detecting defects in the appearance of the developing roller, the light leakage detection assembly 300 is used for detecting light leakage from the developing roller, and the discharging assembly 700 is used for discharging.

[0052] In each embodiment, the feeding component 600, the defect detection component 200, the light leakage detection component 300, and the unloading component 700 are all disposed on the frame 900; as an example, the feeding component 600, the defect detection component 200, the light leakage detection component 300, and the unloading component 700 are all disposed on the frame 900. In other embodiments, the feeding component 600, the defect detection component 200, the light leakage detection component 300, and the unloading component 700 may also be disposed within the frame 900, or have other positional relationships relative to the frame 900; the embodiments of this application do not impose additional limitations in this regard.

[0053] In each embodiment, the defect detection component 200 is disposed between the feeding component 600 and the light leakage detection component 300, and the light leakage detection component 300 is disposed between the defect detection component 200 and the unloading component 700; as an example, the feeding component 600, the defect detection component 200, the light leakage detection component 300 and the unloading component 700 are sequentially arranged on the frame 900 to form a working environment that facilitates assembly line operation.

[0054] As an example, the feeding component 600 is configured to convey the product 110 to be inspected to the defect detection component 200; the defect detection component 200 is configured to detect appearance defects of the product 110 by means of camera shooting, and convey the product 110 that passes the inspection to the light leakage detection component 300; the light leakage detection component 300 is configured to detect light leakage defects of the product 110 by means of camera shooting, and convey the product 110 that passes the inspection to the unloading component 700. This structural design, through the cooperation of the feeding component 600, defect detection component 200, light leakage detection component 300, unloading component 700, and frame 900, proposes an automated integrated inspection design scheme. On the one hand, it captures images of the appearance of the product 110 to be inspected by camera shooting; on the other hand, it captures images of the light leakage condition of the product 110 to be inspected by camera shooting. It should be noted that those skilled in the art will understand that the specific control functions of the feeding component 600, defect detection component 200, light leakage detection component 300, and unloading component 700 can be self-made or purchased directly from the market. They can also be implemented by microprocessors, microcontrollers, control boards, or microcontrollers that can be purchased directly from the market. The embodiments of this application do not involve specific detection methods or control methods; they only need to be able to detect images captured by the camera.

[0055] As an example, the control function can be implemented independently or in conjunction with the display function. In one embodiment, such as Figure 3 As shown, the developing roller appearance inspection device 100 further includes a control and display component 920 disposed on the frame 900. The control and display component 920 is connected to the defect detection component 200 and the light leakage detection component 300, respectively. The control and display component 920 is configured to control the detection of the defect detection component 200 and the light leakage detection component 300, and to display the imaging results of the defect detection component 200 and the light leakage detection component 300. As an example, the control and display component 920 includes a control board, such as a PCB board, which controls the detection of the defect detection component 200 and the light leakage detection component 300 via an electronic switch. The control and display component 920 also includes a display for displaying the images captured by the defect detection component 200 and the detection results, and also for displaying the images captured by the light leakage detection component 300 and the detection results. This structural design facilitates operators' understanding of the inspection status and avoids numerous misjudgments due to improper procedures or process problems, thereby improving yield and production efficiency.

[0056] To facilitate the transfer of the product 110 to be inspected, for example, to facilitate the picking up, placing, or conveying of the product 110, in one embodiment, the developing roller appearance inspection device 100 further includes a clamping and transferring assembly 400 disposed on the frame 900. The clamping and transferring assembly 400 is configured to transfer the light leakage detection assembly 300 in a clamping manner, including transferring the product 110 to be inspected from the loading assembly 600 to the defect detection assembly 200, transferring the product 110 to be inspected that has passed the defect detection assembly 200 to the light leakage detection assembly 300, and transferring the product 110 to be inspected that has passed the light leakage detection assembly 300 to the unloading assembly 700. Since the product 110 to be inspected is a developing roller, which has a cylindrical shape, as an example, the clamping and transferring assembly 400 clamps the product 110 to be inspected by bottom support and side limiting, and transfers the product 110 to be inspected by track transmission or by vertical lifting and rotation.

[0057] It is understood that, in embodiments with a dust removal device assembly 500, the clamping and transferring assembly 400 transfers the light leakage detection assembly 300 in a clamping manner, and further includes transferring the product to be inspected 110 from the feeding assembly 600 to the dust removal device assembly 500, transferring the product to be inspected 110 from the dust removal device assembly 500 to the defect detection assembly 200, and so on. In embodiments with an outer diameter runout detection assembly 800, the clamping and transferring assembly 400 transfers the light leakage detection assembly 300 in a clamping manner, and further includes transferring the product to be inspected 110 that has passed the light leakage detection assembly 300 to the outer diameter runout detection assembly 800, and transferring the product to be inspected 110 that has passed the outer diameter runout detection assembly 800 to the unloading assembly 700.

[0058] In one embodiment, the developing roller appearance inspection device 100 further includes a defective tray 910 disposed on the frame 900, and the clamping and transferring assembly 400 is further configured to transfer the product to be inspected 110 that fails the defect detection assembly 200 or the light leakage detection assembly 300 to the defective tray 910. Similarly, for an embodiment with an outer diameter runout detection assembly 800, the clamping and transferring assembly 400 transfers the light leakage detection assembly 300 in a clamping manner, and also includes transferring the product to be inspected 110 that fails the outer diameter runout detection assembly 800 to the defective tray 910.

[0059] To prevent dust from adhering during transport, in one embodiment, the developing roller appearance inspection device 100 further includes a dust removal device assembly 500, which is disposed on the frame 900 and located between the feeding assembly 600 and the defect detection assembly 200. As an example, the dust removal device assembly 500 is configured to remove dust from the product 110 to be inspected before it enters the detection area of ​​the defect detection assembly 200. In one embodiment, such as... Figure 3 As shown, the dust removal device assembly 500 includes an air-blowing dust removal structure 510 and an electrostatic dust removal structure 520 disposed on the frame 900. The air-blowing dust removal structure 510 is located between the feeding assembly 600 and the electrostatic dust removal structure 520, and the electrostatic dust removal structure 520 is located between the air-blowing dust removal structure 510 and the defect detection assembly 200. This design ensures that the product 110 to be inspected, i.e., the developing roller, undergoes dust removal treatment before entering the detection area of ​​the defect detection assembly 200. For example, it undergoes air-blowing dust removal first, followed by electrostatic dust removal, preventing the product 110 from being misjudged as defective in subsequent inspections due to dust adhering to it.

[0060] To achieve consistency testing of product outer diameter, in one embodiment, such as Figure 3 and Figure 4 As shown, the developing roller appearance inspection device 100 also includes an outer diameter runout detection component 800 disposed on the frame 900. The outer diameter runout detection component 800 is located between the light leakage detection component 300 and the feeding component 700. The outer diameter runout detection component 800 is configured to measure the outer diameter and runout of the product 110 to be inspected, to ensure the consistency of the product 110 to be inspected. This structural design realizes the automatic determination of the outer diameter amplitude inspection item.

[0061] As an example, the good products detected by the outer diameter runout detection component 800, that is, the inspection products 110 that have passed the outer diameter runout detection component 800, are conveyed to the unloading component 700. In an embodiment with a defective bracket 910, the defective products detected by the outer diameter runout detection component 800, that is, the inspection products 110 that have failed the outer diameter runout detection component 800, are conveyed to the defective bracket 910. In an embodiment with a clamping and transferring component 400, the defective products detected by the outer diameter runout detection component 800 are conveyed to the defective bracket 910 via the clamping and transferring component 400. Other embodiments follow the same principle and will not be described in detail.

[0062] In one embodiment, such as Figure 5As shown, the defect detection component 200 includes a camera moving module 210, a line scan camera 220, a line scan camera lens 230, a line scan light source 240, a light source adjustment mechanism 250, a guide rail 260, a first product rotation mechanism 270, and a sliding seat 280.

[0063] Combination Figure 6 The camera moving module 210 and the guide rail 260 are both mounted on the frame 900; the sliding seat 280 is mounted on the guide rail 260 and can slide on the guide rail 260, therefore it can also be said that the sliding seat 280 is mounted on the guide rail 260. As an example, the guide rail 260 is a double rail arranged side by side, or a single-row wide rail, to improve the stability of the sliding seat 280.

[0064] In this embodiment, the first product rotation mechanism 270 is disposed on the sliding seat 280. This structural design allows the first product rotation mechanism 270 to slide together with the sliding seat 280 on the guide rail 260. Furthermore, the first product rotation mechanism 270 is configured to clamp and rotate the product to be inspected 110; that is, while clamping the product to be inspected 110, the first product rotation mechanism 270 can drive the product to be inspected 110 to rotate; or, while driving the product to be inspected 110 to rotate, the first product rotation mechanism 270 clamps the product to be inspected 110. In embodiments with a clamping and transferring assembly 400, the clamping and transferring assembly 400 transfers the product to be inspected 110 from the feeding assembly 600 or the dust removal device assembly 500 to the first product rotation mechanism 270, which then clamps and fixes the product to be inspected 110.

[0065] Combination Figure 7 and Figure 8 In this embodiment, the line scan light source 240 is disposed on the light source adjustment mechanism 250 and arranged side by side with the first product rotation mechanism 270. When the first product rotation mechanism 270 clamps the product to be inspected 110, the line scan light source 240 is configured to emit light that illuminates the product to be inspected 110. The line scan camera 220 is disposed on the camera moving module 210, and the line scan camera lens 230 is disposed on the line scan camera 220. The product to be inspected 110, clamped by the first product rotation mechanism 270, is located between the line scan camera lens 230 and the backlight 360. As an example, the line scan camera 220 is a 16K line scan camera.

[0066] In one embodiment, the line scan light source 240 is rotatably mounted on the light source adjustment mechanism 250. When the first product rotation mechanism 270 clamps the product to be inspected 110, the line scan light source 240 is parallel to the rotation axis of the product to be inspected 110, and the line scan light source 240 is configured to emit light perpendicularly to the product to be inspected 110. This structural design enables automatic CCD appearance inspection. Since the product to be inspected 110 can be rotated while the first product rotation mechanism 270 clamps it, the line scan light source 240 and the line scan camera 220 can present details of the product to be inspected 110 at various positions, thereby ensuring the effectiveness and accuracy of the defect detection component 200 in detecting appearance defects in the product to be inspected 110.

[0067] In one embodiment, such as Figure 9 As shown, the light leakage detection component 300 includes a base 310, a second product rotation mechanism 320, a product pressing mechanism 330, a bearing 350, a backlight 360, a mounting base 370, an area scan camera 380, and an area scan camera lens 390.

[0068] Combination Figure 10 The base 310, the product pressing mechanism 330, the backlight 360, and the mounting base 370 are all disposed on the frame 900. As an example, the base 310 is disposed on the frame 900, and the product pressing mechanism 330 is disposed on the base 310, meaning the product pressing mechanism 330 is indirectly disposed on the frame 900 through the base 310; alternatively, the base 310 and the product pressing mechanism 330 are respectively disposed on the frame 900, meaning the product pressing mechanism 330 is directly disposed on the frame 900. Other embodiments follow the same principle and will not be elaborated further.

[0069] In this embodiment, the second product rotation mechanism 320 is disposed on the base 310, and the second product rotation mechanism 320 is configured to clamp and rotate the product to be inspected 110; similarly, the second product rotation mechanism 320 can drive the product to be inspected 110 to rotate while clamping the product to be inspected 110; it can also be understood that the second product rotation mechanism 320 clamps the product to be inspected 110 while driving the product to be inspected 110 to rotate. In embodiments with a clamping and transferring assembly 400, the clamping and transferring assembly 400 transfers the product to be inspected 110 that has passed the defect detection assembly 200 to the second product rotation mechanism 320, whereby the second product rotation mechanism 320 clamps and fixes the product to be inspected 110, and then performs rotation and detection.

[0070] Combination Figure 11 and Figure 12 The bearings 350 are all disposed on the product pressing mechanism 330, and the bearings 350 are located above the product pressing mechanism 330. The bearings 350 are configured to press down the product 110 to be inspected. The area scan camera 380 is disposed on the mounting base 370, and the area scan camera lens 390 is disposed on the area scan camera 380. The product 110 to be inspected, held by the second product rotating mechanism 320, is located between the area scan camera lens 390 and the backlight 360. This structural design, through the cooperation of the second product rotating mechanism 320, the product pressing mechanism 330, the bearings 350, and the backlight 360, realizes the automatic judgment action of light leakage inspection, providing a suitable environment for light leakage detection of the developing roller. Furthermore, combined with the area scan camera 380 and the area scan camera lens 390, light leakage detection of the developing roller can be performed conveniently, efficiently, and accurately.

[0071] In this embodiment, the light leakage detection component 300 further includes a counterweight placement position 340, which is disposed on the product pressing mechanism 330. The counterweight placement position 340 is configured to drive the bearing 350 to press down the product 110 to be inspected when a counterweight is placed there. This structural design allows the product 110 to be inspected, held by the second product rotating mechanism 320, to receive a certain pressure through the weight of the product pressing mechanism 330 and the counterweight placement position 340 itself, combined with the weight of the placed counterweight, without the application of other external forces. Furthermore, since the product 110 is pressed down by the bearing 350, the bearing 350 can rotate along with the second product rotating mechanism 320 when the product 110 is rotated, thus not affecting the rotation of the product 110 by the second product rotating mechanism 320.

[0072] The following is combined with Figures 1 to 12 The following example illustrates the specific application of the developing roller appearance inspection device 100. In one embodiment, the process flow of the developing roller appearance inspection device 100 is described as follows.

[0073] First, place all the material racks for the products to be inspected 110 so that the feeding assembly 600 can automatically feed them.

[0074] At the loading station, the loading component 600 transports the product 110 to be inspected to the picking range of the clamping and transfer component 400. This design is conducive to realizing the automatic loading of the product 110 to be inspected.

[0075] At the dust removal station, the clamping and transfer component 400 or the dust removal device component 500 rotates the product to be inspected 110 by pressing it against the left and right cylinders, and the dust removal device component 500 performs an electrostatic blowing action on the surface of the product to be inspected 110.

[0076] At the defect detection station, the clamping and transfer component 400 or the defect detection component 200 rotates the product 110 to be inspected by supporting it with left and right servo top cups. The defect detection component 200 performs foreign object inspection and defect inspection on the surface of the product 110 to be inspected.

[0077] At the light leakage detection station, the clamping and transfer component 400 or the light leakage detection component 300 places the product to be inspected 110 on the standard bar and rotates it, while the light leakage detection component 300 performs the light leakage inspection.

[0078] At the outer diameter runout detection station, the clamping and transfer assembly 400 or the outer diameter runout detection assembly 800 rotates the product to be inspected 110 on the laser outer diameter machine, and the outer diameter runout detection assembly 800 detects the outer diameter and amplitude of the product to be inspected 110.

[0079] If all inspections pass, the clamping and transfer assembly 400 transfers the product 110 to be inspected to the unloading assembly 700. Alternatively, if all inspections pass, the clamping and transfer assembly 400 transfers the product 110 to be inspected to the dust removal station, where the dust removal device assembly 500 performs dust removal on the product 110 again, and then the clamping and transfer assembly 400 transfers the product 110 to the unloading assembly 700.

[0080] Throughout the process, if any inspection fails, the clamping and transfer assembly 400 transfers the product to be inspected 110 to the corresponding defective tray 910 at the workstation. For the outer diameter runout detection workstation, two defective trays 910 can be set up. This structural design facilitates the automatic differentiation of defective products.

[0081] This enables automatic clamping of the developing roller before and after automatic CCD inspection, completes the automatic appearance inspection and automatic light leakage inspection of the product 110 to be inspected, and realizes automatic appearance inspection of the developing roller surface, overcoming visual fatigue caused by continuous operation of personnel and ensuring the stability of quality.

[0082] It should be noted that other embodiments of this application also include an implementable developing roller appearance inspection device formed by combining the technical features of the above embodiments.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
