Description

Technical Field

[0001] This application relates to the field of panel inspection equipment technology, and more specifically, to a panel inspection device. Background Technology

[0002] Inspection of OLED (Organic Light-Emitting Diode) panels includes, but is not limited to, the inspection of conductive particles and misalignment in IC (Integrated Circuit) and FPC (Flexible Printed Circuit). Existing panel inspection devices can interface with upstream platforms to achieve automated product inspection, after which the finished products are transported to downstream equipment by an unloading mechanism.

[0003] The product to be tested needs to be placed on the testing platform via a feeding mechanism. The platform's suction unit then adheres and secures the product, followed by image capture via a camera assembly. However, because the product is flexible, the existing platform's suction cups only adhere to the display portion, leaving the gap area containing the IC and FPC unsecured. This results in warping in the gap area, affecting the imaging quality.

[0004] Therefore, how to improve the fixation effect of the product under test and prevent the impact of warping on the detection imaging effect is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0068] This application discloses a panel inspection device to improve the fixation effect of the product to be inspected and prevent the inspection imaging effect from being affected by warping.

[0069] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the application as described in the claims. Additionally, the complete composition represented in the embodiments below is not limited to what is necessary as the solution to the application described in the claims. It should be noted that, for ease of description, only the parts relevant to the application are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0070] When performing offset detection on flexible panels, the panel inspection device needs to move the product to be inspected onto the inspection platform. The product is located in the gap area to be inspected, and then it is inspected by the vision component. When the product to be inspected is a flexible panel, its soft texture makes it prone to wrinkles. The light reflected from the flexible panel will be offset due to the product's warping, and the reflected light path angle will be deflected, preventing it from being captured by the vision component, thus resulting in a dark image captured by the vision component.

[0071] like Figure 1 and Figure 4 As shown in the embodiments of this application, the panel inspection device disclosed includes an inspection platform 300, a vision component 100, a receiving component 200, a loading component 400, and a unloading component 500.

[0072] The detection platform 300 includes an adsorption body 310, which comprises an adsorption body 314, a first adsorption portion 311 disposed on the adsorption body 314, and a second adsorption portion 312 spaced apart from the first adsorption portion 311. The gap between the first adsorption portion 311 and the second adsorption portion 312 is used to place the test portion of the product 800 to be tested. The first adsorption portion 311 and the second adsorption portion 312 are respectively used to adsorb the structure surrounding the test portion of the product 800 to be tested. For example, the product 800 to be tested can be a flexible display module (such as an OLED display module), and the test portion includes an IC region.

[0073] The vision component 100 includes a vision module 110 for inspecting a product 800 on an inspection platform 300. When the product 800 is fixed on the inspection platform 300, the part of the product 800 to be inspected is located in the gap area between the first adsorption part 311 and the second adsorption part 312, so that the vision module 110 can capture an image of the part to be inspected.

[0074] When the vision module 110 is in the detection state, it is located below the detection platform 300, while the product 800 to be detected is fixed above the detection platform 300. The vision module 110 acquires images of the part to be detected through the hollowed-out gap area. The vision module 110 is only located below the detection platform 300 during detection, but it can also remain below the detection platform 300 at all times. Those skilled in the art can choose according to their needs, as long as it can capture images of the gap area when in the detection position.

[0075] The receiving assembly 200 is used to transfer the product 800 to be inspected from the receiving station to the feeding station. For ease of space arrangement, in this embodiment, the panel inspection device has a receiving assembly 200, thereby reducing the movement path of the feeding assembly 400 and facilitating space arrangement. The receiving assembly 200 is used to receive the product 800 to be inspected that has been processed at the previous station at the receiving station, and then transfer the received product 800 to the feeding station.

[0076] The feeding component 400 is used to transport the product 800 to be tested from the feeding station to the testing platform 300. The unloading component 500 is used to transport the tested product to the target location. A corresponding receiving platform can be set up at the target location to receive the tested product.

[0077] The panel inspection apparatus disclosed in this application uses a receiving assembly 200 to transfer the product 800 to be inspected from the receiving station to the feeding station, and a feeding assembly 400 to transfer the product 800 to be inspected from the feeding station to the inspection platform 300. The adsorption body 314, the first adsorption part 311, and the second adsorption part 312 on the inspection platform 300 respectively adsorb different areas of the product 800 to be inspected. There is a gap area between the first adsorption part 311 and the second adsorption part 312, meaning that the first adsorption part 311 and the second adsorption part 312 are located around the gap area, capable of fixing the product 800 to be inspected. When the product 800 to be inspected is adsorbed onto the inspection platform 300, the area to be inspected of the product 800 is located in the gap area between the first adsorption part 311 and the second adsorption part 312. The first adsorption part 311 and the second adsorption part 312 are respectively used to adsorb the structure surrounding the area to be inspected of the product 800 to be inspected, ensuring at least reliable fixing of the area to be inspected. The vision module 110 inspects the product 800 below the inspection platform 300. This application, by adding a first adsorption part 311 and a second adsorption part 312 around the area to be inspected in the product 800, can prevent warping in the area where the area to be inspected is located, thereby improving the inspection imaging effect.

[0078] like Figure 1 and Figure 7As shown, in a specific embodiment of this application, the movement trajectory of the receiving component 200 and the movement trajectory of the loading component 400 are arranged at an angle. The panel detection device also includes a loading / unloading displacement module 900, which has independently controllable loading output end and unloading output end, that is, the loading / unloading displacement module 900 has two output ends (loading output end and unloading output end), and the two output ends can be independently controlled.

[0079] The feeding component 400 is located at the feeding output end, and the unloading component 500 is located at the unloading output end. The feeding component 400 and the unloading component 500 are moved by the feeding displacement module 900 to move the feeding component 400 and the unloading component 500 to the corresponding workstation to perform the corresponding actions.

[0080] It should be noted that the loading component 400 and the unloading component 500 can also use independent displacement modules, that is, the loading component 400 is configured with an independent loading displacement module, and the unloading component 500 is configured with an independent unloading displacement module. In this embodiment, due to the spatial layout, the loading component 400 and the unloading component 500 are on the same straight line when moving between their respective workstations, and therefore share the same displacement module. When the movement paths of the loading component 400 and the unloading component 500 are not on the same straight line, then independent displacement modules need to be configured for the loading component 400 and the unloading component 500. The displacement module is a module capable of outputting linear motion, and it is widely used in industrial equipment. This embodiment does not limit the specific structure of the displacement module.

[0081] The receiving assembly 200 includes a receiving displacement module 210 and a receiving platform 220 disposed on the output end of the receiving displacement module 210. The receiving platform 220 is used to carry the product 800 to be tested. The receiving displacement module 210 drives the receiving platform 220 to reciprocate between the receiving station and the feeding station. When the receiving platform 220 is at the receiving station, it is used to receive the product 800 to be tested that has been processed at the previous station. The corresponding equipment at the previous station places the product 800 to be tested on the receiving platform 220. Driven by the receiving displacement module 210, the receiving platform 220 moves to the feeding station, and the loading assembly 400 then picks up the product 800 to be tested from the receiving platform 220 at the loading station.

[0082] The extension direction of the loading / unloading displacement module 900 is not parallel to the extension direction of the receiving displacement module 210. For example, the extension direction of the loading / unloading displacement module 900 and the extension direction of the receiving displacement module 210 can be designed to be perpendicular, or they can be designed to be at other angles, such as acute or obtuse angles. The specific angle should be designed based on the actual application scenario.

[0083] like Figure 4 and Figure 5As shown in a specific embodiment of this application, the adsorption body 314 includes an adsorption plate 3142 and a support plate 3141 disposed on the adsorption plate 3142. A suction cup 3143 is disposed on the adsorption plate 3142. Side mounting brackets 315 are disposed on both sides of the adsorption plate 3142, and a first adsorption part 311 and a second adsorption part 312 are disposed at intervals on the side mounting brackets 315. The first adsorption part 311 can be indirectly fixed to the side mounting bracket 315 via an adapter 313, and the second adsorption part 312 can be directly fixed to the side mounting bracket 315.

[0084] Specifically, the support plate 3141 has suction cup holes, and the suction cup 3143 extends into the suction cup holes. Since the suction cup 3143 cannot guarantee the flatness of the product 800 under test, especially when the product 800 is a flexible screen, simply supporting the flexible screen with the suction cup 3143 will not guarantee its flatness. In this embodiment, a support plate 3141 is provided on the upper side of the adsorption body 310. The support plate 3141 supports the product 800 under test, ensuring its flatness. The support plate 3141 can also support the display portion of the product 800. Furthermore, the suction cup holes on the support plate 3141 allow the suction force of the suction cup 3143 to act on the product 800 under test, thus adsorbing and fixing it.

[0085] The first adsorption part 311 and the second adsorption part 312 are directly or indirectly fixed between the two side mounting brackets 315. In this embodiment, the first adsorption part 311 and the second adsorption part 312 are supported by the two side mounting brackets 315, which can ensure the reliability of the fixation of the first adsorption part 311 and the second adsorption part 312.

[0086] Both the first adsorption section 311 and the second adsorption section 312 have negative pressure adsorption functions, which are used to adsorb and fix the product to be tested 800, so that the product to be tested 800 can be fixed on the adsorption body 310 for conductive particle detection and offset detection.

[0087] like Figure 5 As shown, the first adsorption part 311 has a first adsorption region, and the first adsorption region is provided with a plurality of first adsorption holes 3111. The first adsorption holes 3111 are used to adsorb the product 800 to be tested in the first region. The first adsorption holes 3111 can be densely distributed in the first adsorption region of the first adsorption part 311. The arrangement density of the first adsorption holes 3111 in the first adsorption region can be designed by those skilled in the art according to their needs. Each first adsorption hole 3111 can generate a negative pressure to adsorb the product 800 to be tested. All the first adsorption holes 3111 can be interconnected, so that a negative pressure source can be used to provide negative pressure to each first adsorption hole 3111, and maintain the same or similar negative pressure suction force for each first adsorption hole 3111.

[0088] The second adsorption section 312 has a second adsorption region, which is provided with a plurality of second adsorption holes 3121. The second adsorption holes 3121 are used to adsorb the product 800 to be tested in the second region. The second adsorption holes 3121 can be densely distributed in the second adsorption region of the second adsorption section 312. The arrangement density of the second adsorption holes 3121 in the second adsorption region can be designed by those skilled in the art according to their needs. Each second adsorption hole 3121 can generate a negative pressure to adsorb the product 800 to be tested. All the second adsorption holes 3121 can be interconnected, so that a negative pressure source can be used to provide negative pressure to each second adsorption hole 3121 and maintain the same or similar negative pressure suction force for each second adsorption hole 3121.

[0089] The first and second regions of the product to be tested 800 are distributed on both sides of the part to be tested, allowing the first adsorption part 311 and the second adsorption part 312 to add fixing points near the part to be tested, thereby ensuring the stability of the part to be tested and improving the detection imaging effect. Moreover, the first and second adsorption regions adopt a microporous adsorption structure, which is particularly suitable for fixing flexible panels. Because the pore size of the first adsorption hole 3111 and the second adsorption hole 3121 is small and densely distributed, it is not easy to adsorb and deform the flexible panel.

[0090] like Figure 5 As shown in a specific embodiment of this application, a notch groove 318 is provided on the side of the second adsorption part 312 near the first adsorption part 311, and the IC area of ​​the part to be tested corresponds to the notch groove 318. This embodiment expands the area of ​​the gap region by providing the notch groove 318, which can correspond to the IC area of ​​the product 800 to be tested. Furthermore, second adsorption holes 3121 are provided around the notch groove 318, thereby increasing the fixation effect on the IC area (which has second adsorption holes 3121 adsorbing and fixing on all three sides).

[0091] Furthermore, the notch groove 318 can be a constricted groove, and the cross-sectional area of ​​the notch groove 318 gradually decreases from the lower side to the upper side of the second adsorption part 312. In this embodiment, by designing the sidewall of the notch groove 318 as an inclined sidewall, the amount of light entering the vision module 110 can also be increased, thereby improving the detection imaging effect.

[0092] like Figure 1 and Figure 4As shown in a specific embodiment of this application, the detection platform 300 may further include a platform displacement module 330, which is used to drive the adsorption body 310 to move between the loading station, the unloading station, and the detection station. The adsorption body 310 is used to receive the product 800 to be tested carried by the loading component 400 at the loading station; the adsorption body 310 is used to allow the unloading component 500 to carry the product that has been tested at the unloading station; and the adsorption body 310 is used to allow the vision module 110 to detect the product 800 at the detection station.

[0093] The moving direction of the platform displacement module 330 can be set to be parallel to the moving direction of the receiving displacement module 210 and perpendicular to the moving direction of the loading and unloading displacement module 900. The specific direction should be set by those skilled in the art according to the actual spatial layout. This embodiment does not limit the moving direction of the platform displacement module 330.

[0094] Furthermore, the detection platform 300 may also include a platform rotation module 320, which is disposed on the output end of the platform displacement module 330. The adsorption body 314 is disposed on the output end of the platform rotation module 320, and the platform rotation module 320 is used to drive the adsorption body 314 to rotate. The rotation axis of the platform rotation module 320 may be designed to be parallel to the vertical direction.

[0095] The receiving assembly 200 also includes a receiving rotation module (not shown in the figure), which is located between the output end of the receiving displacement module 210 and the receiving platform 220. The receiving rotation module can drive the receiving platform 220 to rotate.

[0096] The feeding assembly 400 is equipped with a alignment camera 1000, which is used to complete the first alignment on the receiving platform 220 at the feeding station and the second alignment on the adsorption body 310 at the feeding station.

[0097] The first alignment includes: receiving displacement module 210, loading / unloading displacement module 900 and receiving rotation module, which are used to adjust the relative positional relationship between the product to be tested 800 and the loading component 400 on the receiving platform 220 based on the detection results of the alignment camera 1000.

[0098] The receiving displacement module 210 drives the receiving platform 220 to reciprocate between the receiving station and the feeding station. When the receiving platform 220 is at the receiving station, it is used to receive the product 800 to be inspected after it has been processed at the previous station. Driven by the receiving displacement module 210, the receiving platform 220 moves to the feeding station. Before the loading component 400 grabs the product 800 to be inspected on the receiving platform 220 at the loading station, the alignment camera 1000 needs to perform the first alignment to ensure that the loading component 400 can accurately grab the product 800 to be inspected on the receiving platform 220.

[0099] The alignment camera 1000 can detect the position of the receiving platform 220 at the feeding station. Since the alignment camera 1000 is connected to the loading component 400, its relative position to the loading component 400 is fixed. This allows the relative position between the loading component 400 and the receiving platform 220 to be obtained, and consequently, the relative position between the product 800 to be inspected on the receiving platform 220 and the loading component 400. When the relative position exceeds the preset position, the first alignment operation described above can be performed. Using the actions of the receiving displacement module 210, the loading / unloading displacement module 900, and the receiving rotation module, the relative position between the product 800 to be inspected on the receiving platform 220 and the loading component 400 can be adjusted until the requirements are met.

[0100] The second alignment includes: the platform displacement module 330 and the platform rotation module 320, which are used to adjust the relative positional relationship between the product to be tested 800 and the adsorption body 310 on the feeding assembly 400 based on the detection results of the alignment camera 1000.

[0101] Before the feeding component 400 places the product to be tested 800 on the adsorption body 310, the alignment camera 1000 needs to perform a second alignment to ensure that the feeding component 400 can accurately place the product to be tested 800 on the corresponding position of the adsorption body 310.

[0102] The platform rotation module 320 can adjust the angle of the adsorption body 310 so that the product 800 to be tested on the adsorption body 310 can correspond to the vision module 110. The detection platform 300 may also include a limiting component to restrict the rotation angle of the adsorption body 310, which can prevent the adsorption body 310 from colliding with other components. The limiting component may include a follower 316 fixed on the adsorption body 310 and a fixed limiting component 317 fixed on the base of the platform rotation module 320. The fixed limiting component 317 has a first limiting part and a second limiting part. The follower 316 is located between the first limiting part and the second limiting part. The first limiting part and the second limiting part are used to constrain the two boundaries of the follower 316, thereby constraining the rotation range of the adsorption body 310.

[0103] The alignment camera 1000 is used to detect the position of the adsorption body 310 at the loading station. When the error between the position of the adsorption body 310 and the set position exceeds the set error, the platform displacement module 330 and the platform rotation module 320 can adjust the position and angle of the adsorption body 310 so that the error between the position of the adsorption body 310 and the set position is within the set error range. The loading component 400 then accurately places the product 800 to be tested on the adsorption body 310. Then the platform displacement module 330 transfers the adsorption body 310 to the detection station to ensure the accuracy of the detection.

[0104] like Figure 1 As shown in this embodiment, the panel inspection device may further include a qualified product unloading platform 700 and a non-qualified product unloading platform 600 disposed at the target location. It should be noted that the qualified product unloading platform 700 is used to receive products that pass the inspection, while the non-qualified product unloading platform 600 is used to receive products that fail the inspection. The qualified product unloading platform 700 and the non-qualified product unloading platform 600 can be either hoppers with only a carrying function or conveying mechanisms with a conveying function, the purpose of which is to separate qualified and non-qualified products.

[0105] The feeding component 400 and the unloading component 500 are respectively arranged on both sides of the testing platform 300. The qualified product unloading platform 700, the unqualified product unloading platform 600 and the unloading component 500 can be arranged on the same side of the testing platform 300 to facilitate unloading.

[0106] Both the qualified product unloading platform 700 and the unqualified product unloading platform 600 are located on one side of the receiving component 200 and are arranged at intervals along the moving path of the unloading component 500. The qualified product unloading platform 700 and the unqualified product unloading platform 600 can be arranged in the same area, as long as they are spaced apart, in order to reduce the moving path of the unloading component 500 and reduce the size of the equipment.

[0107] The receiving assembly 200 and the non-conforming product unloading platform 600 are arranged along a first direction. The vision assembly 100 and the inspection platform 300 are both arranged between the receiving assembly 200 and the non-conforming product unloading platform 600, and the vision assembly 100 and the inspection platform 300 are arranged along a second direction. The loading assembly 400 and the unloading assembly 500 are arranged on the same side of the receiving assembly 200 and the non-conforming product unloading platform 600 along the second direction, and the loading assembly 400 and the unloading assembly 500 are arranged along the first direction. The first direction and the second direction form an angle greater than 0°. For example, the first direction and the second direction can be perpendicular.

[0108] like Figure 2 and Figure 3As shown in a specific embodiment of this application, the vision module 110 includes an offset detection camera 111, a particle detection camera 112, a ranging sensor 113, a first displacement adjustment device 115, and a second displacement adjustment device 114.

[0109] The offset detection camera 111 is used to perform offset detection on the part to be inspected of the product 800. The light source of the offset detection camera 111 is a ring light source 1111. The particle detection camera 112 is used to perform conductive particle detection on the product 800. The light source of the particle detection camera 112 is a point light source.

[0110] The integrated circuit (IC) is the core control component that enables various functions of a flexible panel. Its precise positioning directly affects the screen's display quality, signal transmission, and overall performance. If the IC is misaligned, it can lead to poor wiring connections, signal transmission interruptions, and display abnormalities (such as partial non-display or color deviation). The flexible printed circuit (FPC), acting as a bridge connecting various components of the flexible panel (such as the IC and display panel), is responsible for transmitting electrical signals and data. FPC misalignment can cause misalignment of connection points, unstable signal transmission, and affect the display quality and functionality of the flexible panel, potentially even causing the screen to malfunction. Therefore, all flexible panels undergo misalignment testing before leaving the factory.

[0111] The offset inspection camera 111 uses a ring light source 1111. Designing the light source as a ring light source allows the light from the ring light source 1111 to illuminate the product 800 to be inspected in the gap area from multiple angles. This helps to highlight the contours and textures of the object's surface, which is highly advantageous for inspecting flexible panel products with uneven surfaces. Furthermore, the ring light source 1111 provides a uniform light distribution, illuminating the area to be inspected around the product 800, effectively reducing shadows and reflections, and ensuring consistent illumination intensity throughout the gap area. Uniform illumination allows the offset inspection camera 111 to clearly capture every detail of the surface of the product 800, avoiding uneven lighting that could cause some areas to be too bright or too dark, thus affecting the accuracy of the inspection results.

[0112] The ring light source 1111 includes a light-emitting surface, which has a conical structure, and its diameter gradually increases along the light emission direction. In this embodiment, the ring light source 1111's light-emitting surface is designed as a conical structure, which can concentrate the light onto a specific gap area, that is, concentrate the light onto the part of the product 800 to be inspected. This concentrated illumination method can clearly illuminate the key parts of the part to be inspected, making it easier for the offset inspection camera 111 to capture details and improving inspection accuracy.

[0113] In addition, designing the light-emitting surface of the ring light source 1111 as a conical structure can more effectively concentrate the light on the part of the product to be inspected 800, reduce light waste, improve light utilization efficiency, reduce energy consumption to a certain extent, and also achieve better shooting or inspection results under the same lighting conditions.

[0114] Particles on or inside an IC's surface can affect its electrical performance and reliability. Particles can cause short circuits, leakage, and other problems, reducing the IC's lifespan and, in extreme cases, causing complete IC failure, thus affecting the normal operation of the flexible display. Particles on the FPC (Flexible Printed Circuit) can affect its electrical performance, leading to decreased insulation between circuits and increased signal interference. Furthermore, particles can wear down the FPC's surface, reducing its mechanical stability and lifespan. Therefore, all flexible displays require conductive particle testing before leaving the factory.

[0115] In this embodiment, the light source of the particle detection camera 112 is a point light source. The light emitted by the point light source radiates outward from a single point, and when the light shines on the conductive particles, it can outline the particle's contour in a more concentrated manner. Unlike other light sources (such as surface light sources, which may cause light and shadow to be averaged), the point light source can make the edges of the particles clearer under shadow contrast, allowing the particle detection camera 112 to more accurately identify the particle's external size, shape regularity, and other characteristics.

[0116] The distance sensor 113 is used to detect the distance to the product 800 to be inspected. The particle detection camera 112, the offset detection camera 111, and the distance sensor 113 are arranged at intervals along the moving direction of the vision module 110, so that by moving, the particle detection camera 112, the offset detection camera 111, and the distance sensor 113 can be respectively aligned with the product 800 to be inspected to complete the corresponding tasks.

[0117] The offset detection camera 111 is located at the output end of the first displacement adjustment device 115, so as to drive the offset detection camera 111 to move based on the distance value measured by the distance sensor 113; the particle detection camera 112 is located at the output end of the second displacement adjustment device 114, so as to drive the particle detection camera 112 to move based on the distance value measured by the distance sensor 113.

[0118] In this embodiment, the distance between the offset detection camera 111 and the product 800 to be detected can be adjusted by the first displacement adjustment device 115, thereby enabling the offset detection camera 111 to obtain a clearer image. In this embodiment, the distance between the particle detection camera 112 and the product 800 to be detected can be adjusted by the second displacement adjustment device 114, thereby enabling the particle detection camera 112 to obtain a clearer image.

[0119] The distance sensor 113 is used to detect the distance to the product 800 to be detected. The first displacement adjustment device 115 drives the offset detection camera 111 to move based on the distance value detected by the distance sensor 113. The second displacement adjustment device 114 drives the particle detection camera 112 to move based on the distance value detected by the distance sensor 113.

[0120] The control system pre-stores the initial distances between the offset detection camera 111 and the particle detection camera 112 and the product 800 to be inspected (i.e., the offset detection camera 111 and the particle detection camera 112 are in their initial positions). When the difference between the distance value detected by the distance sensor 113 and the initial distance value of the offset detection camera 111 exceeds a preset difference range, the control system controls the first displacement adjustment device 115 to move the offset detection camera 111, so that the actual distance between the offset detection camera 111 and the product 800 to be inspected meets the set requirements. When the difference between the distance value detected by the distance sensor 113 and the initial distance value of the particle detection camera 112 exceeds a preset difference range, the control system controls the second displacement adjustment device 114 to move the particle detection camera 112, so that the actual distance between the particle detection camera 112 and the product 800 to be inspected meets the set requirements. It should be noted that after the product 800 to be inspected is inspected, the particle detection camera 112 and the offset detection camera 111 can return to their initial positions.

[0121] In this embodiment, two ranging sensors 113 may be provided, namely a first ranging sensor 1131 and a second ranging sensor 1132. Along the moving direction of the vision module 110, the first ranging sensor 1131 and the second ranging sensor 1132 are respectively arranged on both sides of the particle detection camera 112.

[0122] Along the moving direction of the vision module 110, the upstream of the first ranging sensor 1131 and the second ranging sensor 1132 serves as the working sensor for detecting the distance to the product 800 to be inspected.

[0123] For example, taking the left-right movement direction of the vision module 110 as an example, when the vision module 110 moves to the left, the ranging sensor 113 on the left side of the particle detection camera 112 first aligns with the product 800 to be detected. That is, the ranging sensor 113 on the left side of the particle detection camera 112 is the working sensor, used to detect the distance to the product 800 to be detected, while the ranging sensor 113 on the right side is idle. The vision module 110 continues to move to the left until the particle detection camera 112 completes the corresponding detection work.

[0124] When the vision module 110 retracts, that is, when the vision module 110 moves to the right, the ranging sensor 113 on the right side of the particle inspection camera 112 first aligns with the product 800 to be inspected. That is, the ranging sensor 113 on the right side of the particle inspection camera 112 becomes the working sensor, used to detect the distance to the product 800, while the ranging sensor 113 on the left side remains idle. The vision module 110 continues to move to the right until the particle inspection camera 112 completes its corresponding inspection work.

[0125] In summary, when two ranging sensors 113 are set, the particle detection camera 112 has no idle stroke during the detection process. That is, it can complete the alignment and detection work by moving to the left and moving back to the right, which improves the detection efficiency.

[0126] When the offset detection camera 111 detects, since it only needs to detect once, and the first ranging sensor 1131 and the second ranging sensor 1132 are both located on the same side of the offset detection camera 111, it is only necessary to designate one of the first ranging sensor 1131 and the second ranging sensor 1132 as the working sensor.

[0127] The distance sensor 113 can be equipped with a position adjustment mechanism to adjust the position of the distance sensor 113. The position adjustment mechanism can be composed of several micrometers, micrometers, etc., so that micrometers or micrometers can be set in the corresponding adjustment direction for adjustment.

[0128] The vision component 100 may further include a vision displacement module 120. A vision module 110 is disposed at the output end of the vision displacement module 120 to drive the vision module 110 to reciprocate. The direction of the reciprocating movement of the vision module 110 may be perpendicular to the movement direction of the platform displacement module 330. In this embodiment, the vision displacement module 120 can drive the vision module 110 to reciprocate, thereby changing the position of the vision module 110. This allows the vision module 110 to be moved below the inspection platform 300 for inspection of the product to be inspected on the inspection platform 300. When there are multiple inspection platforms 300, the movement of the vision module 110 can also be used to inspect the products on each inspection platform 300 separately.

[0129] like Figure 3 As shown, the particle detection camera 112 is mounted on the output end of the second displacement adjustment device 114 via an adjustment mechanism. The adjustment mechanism is used to adjust the angle of the particle detection camera 112. Because the particle detection camera 112 is a line scan camera, it has high requirements for the line scan direction and angle. Adding an adjustment mechanism can adjust the position and angle of the particle detection camera 112, thereby improving the detection accuracy.

[0130] The adjustment mechanism may include an adjustment frame 1122, an adjustment block 1121, and an adjustment screw 1123. The adjustment frame 1122 may be directly or through other intermediate components connected to the output end of the second displacement adjustment device 114. One side surface of the adjustment block 1121 is a curved surface that fits against the outer surface of the particle detection camera 112. The adjustment screw 1123 is threaded onto the adjustment frame 1122, and one end abuts against the adjustment block 1121. There are two adjustment screws 1123, which abut against both ends of the adjustment block 1121 respectively. By rotating the two adjustment screws 1123, the adjustment block 1121 can be driven to move, and the adjustment block 1121 will move the particle detection camera 112, thereby achieving the function of adjusting the angle of the particle detection camera 112.

[0131] It should be noted that the specific structure of the above-mentioned adjustment mechanism is only an example. Those skilled in the art can choose other adjustment structures according to their needs, as long as they can adjust the angle of the particle detection camera 112.

[0132] like Figure 7 As shown, the loading assembly 400 includes a mounting mechanism 410, an execution unit disposed on the mounting mechanism 410, and a drive unit 420 for driving the execution unit to move. The drive unit 420 can be a cylinder. The mounting mechanism 410 is mounted on the loading output end of the loading / unloading displacement module 900.

[0133] The execution unit includes a pressing module 440 and a picking module 430. The picking module 430 is used to pick up and place the product to be tested 800. Specifically, the product to be tested 800 can be adsorbed by negative pressure adsorption. The picking module 430 can release the product to be tested onto the testing platform 300 by cutting off the negative pressure. That is, after the picking module 430 picks up the product from the receiving platform 220, it is placed on the testing platform 300 for the vision module 110 below the testing platform 300 to take pictures and detect it. The pressing module 440 is used to press down the product to be tested to help flatten the product to be tested 800.

[0134] When the feeding component 400 is in the material handling state, the lowest position of the pressing module 440 is higher than the lowest position of the picking module 430. That is, when the feeding component 400 picks up material, the lowest position of the pressing module 440 is higher than the lowest position of the picking module 430. This ensures that when the driving unit 420 drives the picking module 430 and the pressing module 440 to gradually approach the product to be tested, the picking module 430 contacts the product to be tested first. After the adsorption and picking of the product to be tested 800 is completed, the pressing module 440 will not contact the product to be tested 800.

[0135] When the feeding component 400 is in the pressing state, the lowest position of the pressing module 440 is coplanar with or lower than the lowest position of the picking module 430. That is, after the feeding component 400 moves the product 800 to be tested above the testing platform 300, the drive unit 420 drives the picking module 430 and the pressing module 440 to gradually approach the testing platform 300, and the picking module 430 places the product 800 to be tested on the testing platform 300. The drive unit 420 continues to drive the picking module 430 and the pressing module 440 to move downwards until the pressing module 440 presses against the product 800 to be tested, flattening the product 800. After flattening, the negative pressure adsorption force of the testing platform 300 is activated, which then adsorbs and fixes the flattened product 800 to the testing platform 300.

[0136] It should be noted that after the feeding component 400 places the product 800 to be tested onto the testing platform 300, the negative pressure of the feeding component 400 (specifically, the negative pressure of the picking module 430) can be turned off before the pressing module 440 presses onto the product 800. Alternatively, the negative pressure of the feeding component 400 can be turned off after the pressing module 440 presses onto the product 800. After the pressing module 440 presses onto the product 800 and the negative pressure of the feeding component 400 is turned off, the negative pressure of the adsorption body 310 of the testing platform 300 can be turned on after a preset time. Alternatively, the negative pressure of the adsorption body 310 of the testing platform 300 can be turned on simultaneously with the negative pressure of the feeding component 400 after the pressing module 440 presses onto the product 800.

[0137] Both the pressing module 440 and the picking module 430 are retractable structures. The picking module 430 first touches the adsorption body 310 of the detection platform 300. Then, as the driving unit 420 continues to drive the picking module 430 and the pressing module 440 to move downward, the picking module 430 is gradually compressed until the pressing module 440 touches the adsorption body 310 of the detection platform 300 (that is, the lowest position of the pressing module 440 and the lowest position of the picking module 430 are coplanar, that is, the pressing module 440 and the picking module 430 are both pressed onto the product 800 to be tested), thus completing the flattening of the product 800 to be tested.

[0138] Alternatively, an independent lifting drive mechanism can be provided for the pressing module 440. When the feeding component 400 is in the pressing state, the picking module 430 and the pressing module 440 can be driven to move upward as a whole through the drive unit 420, so that the picking module 430 is detached from the adsorption body 310 of the detection platform 300. Then, the pressing module 440 is driven to descend separately through the lifting drive mechanism of the pressing module 440, so that the lowest position of the pressing module 440 is lower than the lowest position of the picking module 430, and the pressing module 440 completes the flattening work of the product 800 to be tested (i.e., only the pressing module 440 is pressed onto the product 800 to be tested).

[0139] In this embodiment, the pressing module 440 can be driven downward by the driving unit 420, so that the pressing module 440 presses against the product 800 to be tested, and flattens the product 800. After the product 800 is flattened by the pressing module 440, the adsorption body 310 supplies negative pressure adsorption force to adsorb and fix the product 800, which can avoid wrinkles on the product 800 and improve the detection imaging effect.
