Description

Technical Field

[0001] This application relates to the field of visual inspection technology, and in particular to a support device and a visual inspection equipment. Background Technology

[0002] Visual inspection equipment is an automated inspection device based on machine vision technology. It acquires image information of the object being inspected through an optical imaging system and uses image processing algorithms to identify and judge features such as defects, dimensions, and locations. Taking circuit board inspection as an example, by acquiring images of the circuit board surface and identifying various defects on the circuit board through image comparison and feature extraction, such as component placement deviations and soldering breaks, non-conforming products can be detected and rejected in a timely manner to ensure product quality.

[0003] However, with the continuous increase in market demand, visual inspection equipment in related technologies still suffers from insufficient inspection efficiency when applied. If it is necessary to improve inspection efficiency, multiple inspection devices are usually used in combination, which not only increases equipment costs but also increases the occupation of production space.

[0023] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] Currently, visual inspection equipment in related technologies suffers from reduced inspection efficiency. To address this issue, manufacturers employ... Figure 17The schematic diagram shows two inspection devices placed side-by-side. Products from the previous station are fed onto two separate conveyor lines, with the distance between the lines increased so that their ends align with the feed positions of the two inspection devices. The products are then visually inspected by both devices. While this approach improves inspection efficiency, it has several limitations: First, it requires two independent inspection devices, increasing equipment costs. Second, the devices are relatively large, requiring significant production space. Third, the large distance between the feed positions necessitates increasing the distance between the two conveyor lines to d2, further increasing the space occupied by the lines. In short, this method of placing two inspection devices side-by-side to improve efficiency suffers from high costs and a large space requirement.

[0027] To address the technical problems existing in visual inspection equipment in related technologies, this application provides a support device for use in visual inspection equipment. This application also provides a visual inspection device that includes the support device and at least two visual inspection devices.

[0028] In this application, the support device is used at least to support the product and keep the product in the inspection channel, so that the vision inspection device can acquire product images and perform visual inspection.

[0029] The support device and visual inspection equipment of this application are configured with multiple support mechanisms on a single frame. These support mechanisms work together to provide at least two inspection channels. Visual inspection devices are arranged on both sides (e.g., the top and bottom sides) of the support device, enabling dual-channel, double-sided inspection within a single visual inspection device. This improves inspection efficiency while maintaining a compact overall structure and minimizing space requirements. Furthermore, while integrating dual inspection channels, the width d3 of each inspection channel is adjustable to accommodate products of different sizes, meet diverse inspection needs, and balance inspection efficiency, cost control, and flexibility.

[0030] Please refer to the following. Figures 1 to 16 This application describes the supporting device and the visual inspection equipment using it. For ease of understanding, this application uses the x, y, and z directions as auxiliary descriptions to illustrate the relative positional relationships between the relevant components. The x, y, and z directions are perpendicular to each other. For example, the x direction is the front-back direction, the y direction is the left-right direction, and the z direction is the up-down direction.

[0031] Reference Figures 1 to 3 , Figure 7The support device includes a frame, multiple support mechanisms 20, and multiple width-adjusting transmission components 30. The vision inspection equipment includes the support device and at least two vision inspection devices 90, each including an inspection camera, etc.

[0032] The frame is the skeleton of the entire support system, serving to support and secure other components. (Refer to...) Figure 1 , Figure 2 The frame includes at least two bases 11, and this application uses a frame including two bases 11 as an example. The at least two bases 11 are spaced apart along the x-direction, and a clearance space is formed between adjacent bases 11. This clearance space provides an optical path to facilitate the acquisition of product images by the vision inspection device 90. Each base 11 extends along the y-direction, providing a foundation for the installation and movement of subsequent components.

[0033] Continue to refer to Figures 1 to 3 , Figure 7 Multiple support mechanisms 20 are arranged along the y-direction, and each support mechanism 20 extends along the x-direction. A first end of each support mechanism 20 is mounted on one base 11, and a second end is mounted on another base 11; that is, both ends of the support mechanism 20 are connected to the two bases 11 respectively, and the support mechanism 20 is arranged transversely between the two bases 11. The support device includes at least two detection channels 100. The detection channel 100 is provided between two adjacent support mechanisms 20 in the y-direction, and the detection channel 100 is used to accommodate the product to be detected. In this embodiment, the two detection channels 100 are formed by four support mechanisms 20 in pairs; in other embodiments, the two detection channels 100 may also be formed by three support mechanisms 20 in pairs.

[0034] Continue to refer to Figure 1 , Figure 3 The inspection channel 100 extends through the z-direction, with one side of the inspection channel 100 forming a clearance space between two bases 11. The visual inspection equipment includes at least two visual inspection devices 90, arranged on opposite sides of the inspection channel 100 in the z-direction, with their lenses both facing the inspection channel 100. At least one visual inspection device 90 is used to acquire images of the upper surface of the product located in the inspection channel 100, and at least one visual inspection device 90 is used to acquire images of the lower surface of the product located in the inspection channel 100. Taking the z-direction as the vertical up-down direction as an example, the inspection channel 100 extends vertically, and multiple support mechanisms 20 are arranged above the two bases 11 of the frame. Because the two bases 11 are spaced apart, the lower surface of the circuit board located in the inspection channel 100 is not obstructed by the bases 11, allowing the visual inspection device 90 located below to capture images of the lower surface of the circuit board in the inspection channel 100 from bottom to top without being obstructed by the frame bases 11.

[0035] Taking a circuit board (PCBA or PCB, where PCB refers to a printed circuit board and PCBA refers to a PCB with assembled components) as an example, the circuit board is transported to the inspection channel 100 via a transmission line or robotic arm. Support mechanisms 20 on both sides support the two sides of the circuit board, thus providing support. This support method also exposes the upper and lower surfaces of the circuit board, allowing the vision inspection device 90 to capture images of these surfaces for defect detection.

[0036] In this application, the width d3 (i.e., the dimension of the detection channel 100 in the y-direction) of each detection channel 100 is adjustable. The detection channel 100 is configured such that the support mechanism 20 located on one or both sides of the detection channel 100 is a movable mechanism 201 that moves relative to the frame in the y-direction. That is, the two ends of the movable mechanism 201 can slide along the base 11 respectively. The base 11 provides guidance for the sliding of the movable mechanism 201, enabling the movable mechanism 201 to move as a whole in the y-direction. This allows the two support mechanisms 20 used to define the detection channel 100 to move closer or further apart, thereby increasing or decreasing the width d3 of the detection channel 100 to accommodate products with different widths.

[0037] Taking the installation of multiple support mechanisms 20 on the upper side of the base 11 as an example, a detection channel 100 is formed between two adjacent support mechanisms 20, and a clearance space is formed between two adjacent bases 11, located below the detection channel 100. When the product is sent to the detection channel 100 to be jointly supported by the support mechanisms 20 on both sides, the gaps between the two support mechanisms 20 and between the two bases 11 prevent the obstruction of the lower and upper surfaces of the product, thus facilitating the acquisition of images of the upper and lower surfaces of the product by the two visual inspection devices 90 respectively, achieving double-sided inspection.

[0038] In order to enable the support mechanism 20 to move along the base 11 under the action of external power to adjust the width of adjacent detection channels 100, the support device is configured as follows: the two ends of the movable mechanism 201 are respectively connected to the base 11 on both sides through two sets of width adjustment transmission components 30. The width adjustment transmission component 30 has an input end, which can transmit driving force to the input end through the drive component 40 (such as a motor) or through the user's hand. After receiving the driving force, the width adjustment transmission component 30 can drive the movable support mechanism 20 (i.e., the movable mechanism 201) to move relative to the base 11 in the y direction under the action of the driving force, thereby realizing the adjustment of the width of the detection channel 100.

[0039] This application has the following advantages through structural design, such as setting bases 11 at intervals in the x-direction, setting support mechanisms 20 at intervals in the y-direction, and configuring some of the support mechanisms 20 to be connected to the bases 11 on both sides through width-adjusting transmission components 30 at both ends.

[0040] First, it enables multi-channel double-sided inspection, improving inspection efficiency. This application integrates multiple inspection channels 100 into a single vision inspection device, with corresponding vision inspection devices 90 configured on both sides of each inspection channel 100. For example, when inspecting circuit boards, two circuit boards can be simultaneously fed into two inspection channels 100, and the vision inspection devices 90 on the upper and lower sides can respectively acquire images of the upper and lower surfaces of the circuit boards for defect detection. This parallel inspection method shortens inspection time, improves inspection efficiency, and can meet the rapid and efficient inspection needs of large-scale production lines.

[0041] Secondly, it reduces equipment costs and space requirements. On the one hand, compared to using multiple independent testing devices, this application only requires the purchase of one device, significantly reducing equipment procurement costs. On the other hand, due to its compact overall structure and small space occupation, it eliminates the need to place two independent devices together on the testing line, avoiding the problem of excessive space occupation caused by equipment splicing. Simultaneously, the feed inlets of the two testing channels 100 can be closer together, resulting in a smaller spacing d1 between the two transmission lines from the previous station to the testing station (e.g., ...). Figure 16 (Illustrative image), and Figure 17 Compared with schemes where the spacing d2 between two adjacent transmission lines is larger, this application saves the space occupied by the transmission lines, which is conducive to improving the utilization rate of the production site and reducing the site rental or construction costs.

[0042] Third, the width of the detection channel 100 is adjustable, balancing detection efficiency and flexibility. By adjusting the width of the transmission assembly 30, which, under the action of driving force, moves the movable support mechanism 20 along the y-direction relative to the base 11, the width of the detection channel 100 can be increased or decreased. This design allows the equipment to flexibly adapt to products of different sizes and specifications. Whether it's a narrow, small circuit board or a wide, large circuit board, it can stably support and detect them by adjusting the width of the detection channel 100.

[0043] In practical applications, this testing equipment demonstrates good applicability: on the one hand, for products of the same specification, they can be sent to multiple testing channels 100 simultaneously for double-sided testing, shortening the testing time for a single specification product; on the other hand, for products of different specifications (such as circuit boards of different sizes), they can be sent to different testing channels 100 of appropriate width for double-sided testing according to the product size. Each testing channel 100 is independently and flexibly adapted to different products, achieving efficient parallel testing of multiple specifications of products while ensuring testing quality. This avoids interruptions or reduced efficiency in the testing process due to differences in product specifications, and can improve testing efficiency in different scenarios.

[0044] In one embodiment, the support device includes two detection channels 100, and the visual inspection equipment includes two visual inspection devices 90. By using the two detection channels 100 and the two visual inspection devices 90 in the same device, high inspection efficiency can be achieved while maintaining a compact structure. In actual inspection, any of the following inspection methods can be used.

[0045] The first inspection method involves simultaneous operation of the upper and lower vision inspection devices 90, which simultaneously inspect the upper and lower surfaces of the products in the first inspection channel 100 for defects. After inspecting the first inspection channel 100, the two vision inspection devices 90 then simultaneously inspect the upper and lower surfaces of the products in the second inspection channel 100, thus completing the double-sided inspection of the products in both inspection channels 100. In this first inspection method, while the products in the first inspection channel 100 are being inspected for defects on both the upper and lower surfaces by the two vision inspection devices 90, the second inspection channel 100 can be used for either the unloading of completed products from the inspection channel 100 or the feeding of products to be inspected into the inspection channel 100. This allows for double-sided inspection of products in one inspection channel 100 and the feeding and unloading operations of the inspection station in another channel, resulting in high efficiency and improved inspection efficiency.

[0046] The second inspection method is as follows: In the same equipment, the upper visual inspection device 90 first inspects the upper defects of the products in the first inspection channel 100, while simultaneously, the lower visual inspection device 90 inspects the lower defects of the products in the second inspection channel 100. After the inspection is completed, the two visual inspection devices 90 move along the y-direction, and then the upper visual inspection device 90 inspects the upper defects of the products in the second inspection channel 100, and the lower visual inspection device 90 inspects the lower defects of the products in the first inspection channel 100. In this way, the inspection of defects on the upper and lower sides of the products in the two inspection channels 100 is completed alternately.

[0047] In one embodiment, reference is made to Figure 2 , Figure 16The support mechanism 20 is equipped with a conveying assembly 60 that transports products along the x-direction. After the product enters the support mechanism 20 from the previous station, it is sent into the inspection channel 100, with both sides of the product contacting the conveying assemblies 60 located on the support mechanisms 20 on either side. During inspection, the conveying assemblies 60 on both sides not only carry the product but also simultaneously transport it to the center of the inspection channel 100, centering the product and facilitating accurate image acquisition by the vision inspection device 90, thereby improving inspection accuracy. After inspection, the conveying assemblies 60 transport the product out of the inspection channel 100 along the x-direction to the next station. In this embodiment, by configuring the conveying assemblies 60 on the support mechanism 20, for example, by setting the conveying assemblies 60 on the inner sides of the two support mechanisms 20 used to define the inspection channel 100, the support mechanism 20 not only has the simple function of carrying products but also the ability to transport products, ensuring the continuity of the process before, during, and after inspection and improving inspection efficiency.

[0048] Optionally, the support mechanism 20 includes a support plate and support columns. The support plate extends along the x-direction, and the support columns are connected to both ends of the support plate and extend to the same side. The two side support columns are connected to the middle support plate to form a gate-like structure. The two side support columns are directly or indirectly connected to the bases 11 on both sides, respectively, to realize the installation of the support mechanism 20. The conveying assembly 60 is disposed on the inner side of the support plate. For example, the conveying assembly 60 includes a conveyor belt, a power source for conveying, and a tensioning wheel for tensioning the conveyor belt.

[0049] In one embodiment, reference is made to Figures 1 to 3 , Figure 7 The support device includes four support mechanisms 20, namely a first support mechanism, a second support mechanism, a third support mechanism, and a fourth support mechanism. The first and second support mechanisms define a first detection channel 100, and the third and fourth support mechanisms define a second detection channel 100. It is understood that the two detection channels 100 do not share any support mechanisms 20, which enhances the independence of the two detection channels 100. The width of a single detection channel 100 can be adjusted independently as needed. If one detection channel 100 fails, the other detection channel 100 can still be used. It also reduces mutual interference. For example, when performing high-precision detection on the circuit board of the first detection channel 100, because the second and third support mechanisms 20 are independent, the vibration generated during the transmission or detection of the circuit board in the second detection channel 100 has less interference with the circuit board in the first detection channel 100, avoiding blurring or deviation of the detection image due to vibration, and ensuring detection accuracy and precision.

[0050] In other embodiments, the support device may also provide two detection channels 100 through the cooperation of three support mechanisms 20. Alternatively, in other embodiments, the support device may be provided with more than two detection channels 100, for example, six support mechanisms 20 may be provided to provide three detection channels 100.

[0051] In one embodiment, based on the support device being configured with four support mechanisms 20 to provide two detection channels 100, the support mechanisms 20 can be configured in any of the following ways to achieve adjustment of the width of the detection channels 100.

[0052] One configuration of the support mechanism: the first support mechanism, the second support mechanism, the third support mechanism, and the fourth support mechanism are all movable mechanisms 201.

[0053] Support mechanism configuration method two: such as Figure 2 The diagram illustrates that the first support mechanism is a fixed mechanism 202 (the fixed mechanism 202 refers to a support mechanism 20 that is relatively fixed to the base 11 on both sides by means of screws, snap-fit ​​connections, etc.), while the second, third, and fourth support mechanisms are configured as movable mechanisms 201. The first support mechanism 20 is fixed, providing an adjustment reference for the two detection channels 100, and reducing the number of support mechanisms 20 that need adjustment, thus simplifying the structure. When the width of the detection channel 100 needs to be adjusted, the positions of one, two, or all three of the other three support mechanisms 20 can be flexibly adjusted. Furthermore, when the width of the first detection channel 100 is appropriate but the width of the second detection channel 100 is inappropriate, only the position of the fourth support mechanism 20 needs to be adjusted individually, making the operation convenient and efficient.

[0054] The third configuration of the support mechanism: the first and fourth support mechanisms are configured as movable mechanisms 201, and the second and third support mechanisms are fixed mechanisms 202.

[0055] The fourth configuration of the support mechanism 20: the second and third support mechanisms are configured as movable mechanisms 201, and the first and fourth support mechanisms are fixed mechanisms 202.

[0056] In one embodiment, reference is made to Figures 1 to 6The width-adjusting transmission assembly 30 includes a sliding seat 31 and a lead screw 32. The end of the movable mechanism 201 is fixedly connected to the sliding seat 31 so that the sliding seat 31 and the movable mechanism 201 can move synchronously. The sliding seat 31 is slidably mounted on the base 11. For example, the base 11 is provided with a slide rail 12, and the sliding seat 31 is provided with a slide groove. By assembling the slide rail 12 with the slide groove, the sliding seat 31 can be slidably mounted on the base 11 in the y-direction. A rod support 13 is fixedly provided on the base 11 and is fixedly connected to the base 11. The lead screw 32 is rotatably mounted on the rod support 13. The rod support 13 supports the lead screw 32 and allows the lead screw 32 to rotate relative to the rod support 13.

[0057] The lead screw 32 and the sliding seat 31, located in the same width-adjusting transmission assembly 30, are threadedly connected. For example, a rod nut 33 is threaded onto the external part of the lead screw 32, and the rod nut 33 is fixedly connected to the sliding seat 31. It should be noted that the same width-adjusting assembly 30 includes a lead screw 32 and a sliding seat 31 that cooperate to transmit power to the same end of the same movable mechanism 201. Figure 10 As shown, the movable mechanism 201 has two sets of width adjustment transmission components 30 at its two ends. For example only, each width adjustment transmission component 30 includes a lead screw 32 and a sliding seat 31.

[0058] It should be noted that when there are multiple movable mechanisms 201, such as Figure 1 , Figure 7 Multiple width-adjusting transmission components 30 are provided on the same side base 11 to correspond to the ends of multiple movable mechanisms 201 respectively. Taking three sliding seats 31 slidably installed on one side base 11 as an example, three lead screws 32 are correspondingly configured. Taking the first lead screw 32 as an example, it can be connected to any one of the first, second, and third sliding seats 31 in a transmission connection, and does not necessarily need to be combined in a specific order.

[0059] Optionally, Figure 5 , Figure 11 The sliding seat 31 includes a first seat body 311 and a second seat body 312, which are connected by fasteners, snap-fit ​​connections, or other means. The first seat body 311 has a groove on its side opposite to the second seat body 312 for sliding installation on the slide rail 12. The second seat body 312 has multiple through holes 313 for assembly with the lead screw 32. In other embodiments, the first seat body 311 and the second seat body 312 may be a single integral component.

[0060] Optionally, the rod support 13 is provided with a support hole, in which a bearing is installed. The end of the lead screw 32 is installed on the bearing, so that the lead screw 32 and the rod support 13 are rotatably connected. A bearing pressure plate is also installed at the opening of the support hole of the rod support 13 to prevent the bearing from running out of space and to prevent the lead screw 32 from running out of space.

[0061] It should be noted that the two components in this manual are relatively fixedly connected, which can be achieved by one or more of the following methods: fastener connection, snap-fit ​​connection, welding connection, magnetic connection, integral molding connection, etc.

[0062] Optionally, each base 11 of the support device includes a slide rail 12, on which multiple sliding seats 31 are mounted. The number of sliding seats 31 is the same as the number of movable mechanisms 201. Two rod supports 13 are respectively provided at both ends of the slide rail 12 in the y-direction. In this way, the two ends of the lead screw 32 are rotatably mounted on the two rod supports 13 respectively. The lead screw 32 is threadedly connected to the corresponding sliding seat 31 above the slide rail 12. The rod supports 13 on both sides provide installation stability and rotational guidance for the lead screw 32. The sliding seat 31 in the middle, which cooperates with the lead screw 32, realizes the conversion of rotational motion into linear motion to drive the movable mechanism 201 to move. The overall structure is compact and has high transmission stability.

[0063] Optionally, each base 11 is provided with only one slide rail 12. With multiple lead screws 32 and multiple sliding seats 31 arranged in a compact manner, a single slide rail 12 can meet the guiding requirements of the linear movement of the sliding seat 31. The sliding seat 31 is subjected to stable force without uneven force distribution. Furthermore, a single slide rail 12 requires less installation space, making the entire support device more compact and saving space.

[0064] Taking a vision inspection device including a motor as an example, the motor acts as a drive source and is connected to the lead screw 32 of the width adjustment transmission assembly 30. When it is necessary to adjust the width of the inspection channel 100, the motor starts, and the power is transmitted directly or indirectly to the lead screw 32, causing the lead screw 32 to rotate. Since the lead screw 32 is rotatably mounted on the rod bracket 13 fixed on the base 11 and connected to the sliding seat 31 through a threaded pair, the rotational motion of the lead screw 32 is converted into a thrust that drives the sliding seat 31 to move linearly along the slide rail 12 on the base 11. The sliding seat 31 drives the movable mechanism 201, which is fixedly connected to it, to move synchronously. The two ends of the movable mechanism 201 are respectively connected to the two sliding seats 31 on both sides. Thus, under the drive of the motor, the movable mechanism 201 moves as a whole in the y-direction, moving closer to or away from the movable mechanism 201 on the other side of the inspection channel 100, thereby realizing the adjustment of the width of the inspection channel 100.

[0065] In this embodiment, a threaded drive is employed, which features self-locking and high transmission accuracy. This not only allows for precise control of the moving distance of the movable mechanism 201, improving the accuracy and speed of the width adjustment of the detection channel 100, but also ensures that the adjusted support mechanism 20 remains stably in its current position during the detection phase after width adjustment, thus stably supporting the product to be inspected. Furthermore, the width adjustment transmission assembly 30 mainly consists of a sliding seat 31 and a lead screw 32, resulting in a relatively simple structure and small footprint. In visual inspection equipment, this saves valuable installation space, making the overall structure more compact and facilitating layout and installation. In addition, both ends of the lead screw 32 can serve as power input sources, allowing for flexible adjustment according to requirements, such as... Figure 7 , Figure 10 As shown, one end of the lead screw 32 is connected to the motor drive to facilitate power input through an electric drive source, and the other end of the lead screw 32 is connected to the manual dial 50. The user can manually rotate the manual dial 50 to drive the lead screw 32 to rotate, thereby fine-tuning the position of the support mechanism 20.

[0066] In one embodiment, to facilitate adjustment of the width of the detection channel 100, the number of width-adjusting transmission components 30 provided on each base 11 is consistent with the number of movable mechanisms 201 in the support device, thereby achieving individual adjustment and control of the position of each movable mechanism 201. For example, the support device has three support mechanisms 20 that are movable mechanisms 201; correspondingly, each base 11 is equipped with three sets of width-adjusting transmission components 30, such as... Figures 1 to 3 , Figure 7 As illustrated, three sliding seats 31 are slidably mounted on the left and right bases 11, respectively, and each sliding seat 31 is threadedly connected to a lead screw 32. In this embodiment, each movable mechanism 201 has two ends that cooperate with a set of width-adjusting transmission components 30. This design ensures that power can be transmitted to each movable mechanism 201 through an independent path, and also ensures that both ends of the movable mechanism 201 can receive power, thereby making the forces on both ends uniform and moving synchronously, effectively avoiding the skewness of the movable mechanism 201.

[0067] In other embodiments, one end of the movable mechanism 201 is connected to the base 11 via a width-adjusting transmission assembly 30, and the other end is directly and slidably mounted on the base 11.

[0068] In one embodiment, reference is made to Figure 1 , Figure 3 , Figure 7 , Figures 13 to 15The width adjustment transmission assembly 30 includes the sliding seat 31 and the lead screw 32 in any of the aforementioned embodiments. Multiple width adjustment transmission assemblies 30 are provided on each base 11, and each base 11 is provided with a slide rail 12 that moves along the y-direction. Multiple sliding seats 31 are arranged along the y-direction and are all slidably connected to the slide rail 12. That is, multiple sliding seats 31 on the same base 11 are mounted on the same slide rail 12. This reduces the number of slide rails 12 and also helps to reduce the space occupied by multiple width adjustment transmission assemblies 30 on a single base 11 in the x-direction, thereby improving the compactness of the support device in the x-direction. This achieves both increased detection channels 100 and improved detection efficiency while maintaining compactness. In addition, multiple sliding seats 31 are installed on the same slide rail 12, which can effectively ensure their motion consistency and make the adjustment of the movable mechanism 201 more precise and stable; the first ends of the multiple movable mechanisms 201 all move along the trajectory of the first side slide rail 12, and the second ends all move along the trajectory of the second side slide rail 12; in this way, even after adjusting the width of the detection channel 100, the relative angle between two adjacent support mechanisms 20 can still maintain the preset state, such as remaining parallel, thereby reliably supporting the two sides of the product.

[0069] In one embodiment, the width adjustment transmission assembly 30 includes the sliding seat 31 and the lead screw 32 as described in any of the preceding embodiments. Multiple width adjustment transmission assemblies 30 are provided on each base 11, capable of driving multiple movable mechanisms 201 respectively, thereby achieving flexible and precise adjustment of the width of the detection channel 100. For example, in the embodiment shown in the accompanying drawings, three width adjustment transmission assemblies 30 are provided on a single base 11, meaning three sliding seats 31 are slidably mounted on a single base 11, which can satisfy the independent driving of three movable mechanisms 201, thereby constructing a suitable detection channel 100.

[0070] Please refer to Figure 11 , Figure 12 Each movable seat is provided with multiple through holes 313, as shown in the reference. Figure 5 , Figure 6At least some of the through holes 313 serve as via holes 3132. Each base 11 is provided with multiple width-adjusting transmission assemblies 30, and the sliding seat 31 is threadedly connected to the lead screw 32 within the same width-adjusting transmission assembly 30 to achieve its linear motion. To allow the multiple sliding seats 31 on the same base 11 to coexist in the same space with the lead screw 32 of the width-adjusting transmission assembly 30, the lead screws 32 in the other width-adjusting transmission assemblies 30 on the same base 11 pass through the via holes 3132 of the sliding seat 31. Different lead screws 32 can pass through different via holes 3132 or the same via hole 3132, as long as adjacent lead screws 32 do not interfere with each other. In this way, interference between the sliding seat 31 and the lead screw 32 in other width-adjusting transmission components 30 can be avoided, so that the movement adjustment between different movable mechanisms 201 can be independent and do not interfere with each other. It also allows the components of different components to be relatively close and compact, thereby reducing the space occupied by multiple width-adjusting transmission components 30. While improving detection efficiency, it also keeps the visual inspection equipment as compact and reduces its size as much as possible.

[0071] Optionally, such as Figure 5 , Figure 6 As shown, the wall of the through hole 3132 of the sliding seat 31 maintains a fitting gap with the outer wall of the lead screw 32 in the other width-adjusting transmission assembly 30. The two do not contact each other and there is no power transmission.

[0072] In other embodiments (not shown in the figure), a bearing is provided in the through hole 3132 of the sliding seat 31, and the lead screw 32 in the other width adjustment transmission components 30 passes through the inner hole of the bearing. In this way, the sliding seat 31 not only cooperates with the lead screw 32 in the same width adjustment transmission component 30 to form a threaded pair to realize the conversion between rotary motion and linear motion, but the sliding seat 31 also provides rotational guidance and support for the lead screw 32 in the other width adjustment transmission components 30.

[0073] In one embodiment, multiple sliding seats 31 are provided on the same base 11, and the multiple sliding seats 31 are configured to slide along the same trajectory (for example, multiple sliding seats 31 on the same base 11 are slidably mounted on the same slide rail 12). Furthermore, through holes 3132 are provided on the sliding seats 31. The through holes 3132 are designed to allow components of different width-adjusting transmission assemblies 30 to intersect each other in space, achieving space reuse and making the entire support device structure compact, which is beneficial for reducing the overall size of the support device. For example, when space is limited in a production site, if a conventional design is used, it is difficult to set multiple detection channels 100 in a single device within a limited space. However, using the solution of this embodiment, multiple detection channels 100 can be provided without significantly increasing the size of the detection device.

[0074] In one embodiment, reference is made to Figure 1Each detection channel 100 is a through channel in the z-direction, so that both sides of the detection channel 100 in the z-direction can be used to arrange the visual inspection device 90. For example, the z-direction is the vertical direction, and both the upper and lower sides of the detection channel 100 are used to arrange the visual inspection device 90.

[0075] Optionally, the multiple lead screws 32 in the multiple width-adjusting transmission assemblies 30 mounted on the same base 11 are arranged in one of the following arrangements.

[0076] One arrangement of multiple lead screws (32): such as Figures 1 to 7 , Figure 13 As shown, multiple lead screws 32 are arranged sequentially along the z-direction, that is, multiple lead screws 32 are arranged sequentially along the vertical direction. This reduces the space occupied in the x-direction. This arrangement can be used when there are dimensional restrictions in the x-direction for the support device. In this case, [the following can be used]. Figure 11 or Figure 12 The schematic diagram shows the structure of the sliding seat 31.

[0077] The second arrangement of multiple lead screws (32): such as Figure 14 As shown, multiple lead screws 32 are arranged sequentially along the x-direction, that is, multiple lead screws 32 are arranged sequentially along the horizontal direction. In this way, the space occupied in the z-direction can be reduced. This arrangement can be used when there are height restrictions on the support device.

[0078] The third arrangement of multiple lead screws: such as Figure 15 As shown, three sets of width-adjusting transmission components 30 are installed on the same base 11, and three lead screws 32 are configured accordingly. The three lead screws 32 are arranged in a triangular manner, with two lead screws 32 close to the base 11 and spaced apart along the x-direction, and the other lead screw 32 is set higher. This arrangement can be used when there are overall volume restrictions on the support device.

[0079] In one embodiment, to improve the transmission reliability of the sliding seat 31 and the lead screw 32 in the same width adjustment assembly, and to improve the compactness between different width adjustment assemblies, the width adjustment transmission assembly 30 is configured in the following manner. For example... Figure 11 or Figure 12 As shown, each sliding seat 31 is provided with multiple through holes 313, one of which is a mounting hole 3131, and the remaining through holes 313 are through holes 3132. For example... Figure 5 , Figure 6 The width adjustment transmission assembly 30 includes a rod nut 33. In the same width adjustment transmission assembly 30, the rod nut 33 is fixed in the mounting hole 3131, and the lead screw 32 passes through the rod nut 33 and is threadedly connected to the rod nut 33. The through hole 3132 is used for the lead screw 32 in the other width adjustment transmission assemblies 30 to pass through.

[0080] It is understandable that in the same width-adjusting transmission assembly 30, the threaded engagement between the lead screw 32 and the sliding seat 31 is achieved through the configuration of the rod nut 33, which drives the sliding seat 31 to move on the base 11 when the lead screw 32 rotates. During processing, a conventional through hole 313 is directly drilled in the sliding seat 31, and then the standard part rod nut 33 is fixed in the mounting hole 3131 by any method such as interference fit, welding, or fastener locking. Then, the lead screw 32 is screwed in, and the assembly is completed. The structure and assembly process are both simple. At the same time, a through hole 3132 is specially designed on the sliding seat 31 for the lead screws 32 in other width-adjusting transmission assemblies 30 to pass through. This cleverly solves the layout problem of multiple width-adjusting transmission assemblies 30 in a limited space. By setting the through hole 3132, the lead screws 32 of different width-adjusting transmission assemblies 30 can be interspersed in space, avoiding mutual interference and collision between the lead screws 32. This allows the width-adjusting transmission assemblies 30 to be arranged closely adjacent to each other, significantly improving the compactness between different width-adjusting assemblies and facilitating the installation and layout of the equipment on the production line.

[0081] Reference Figure 11 In some embodiments, adjacent through holes 313 on the sliding seat 31 are spaced apart to ensure independence and structural strength of the sliding seat 31. In other embodiments, such as Figure 12 As shown, the sliding seat 31 has multiple through holes 313, and the edges of adjacent through holes 313 are directly connected to achieve interconnection between adjacent through holes 313, resulting in a more compact layout and saving space. When there are extreme requirements for the shape of the support device, multiple through holes 313 can be connected to form a configuration.

[0082] In one embodiment, reference is made to Figure 1 , Figure 2 , Figures 7 to 9 The support device includes a drive assembly 40, which includes a drive mechanism 41 and a transmission assembly. The transmission assembly includes a driving transmission element 42, a synchronous transmission element 43, and a driven transmission element 44. The output shaft of the drive mechanism 41 is connected to the driving transmission element 42, and the driving transmission element 42 is connected to the driven transmission element 44 through the synchronous transmission element 43. A lead screw 32 connected to one end of the movable mechanism 201 is connected to the driving transmission element 42, and a lead screw 32 connected to the other end of the movable mechanism 201 is connected to the driven transmission element 44.

[0083] The drive mechanism 41 can be, but is not limited to, a motor. When the width of the detection channel 100 needs to be adjusted, the drive mechanism 41 outputs power, forming two power transmission paths. One path transmits power through the drive mechanism 41 and the active transmission member 42 to the width adjustment transmission assembly 30 located on the first side of the movable mechanism 201, thereby driving the first end of the movable mechanism 201; the other path transmits power through the drive mechanism 41, the active transmission member 42, the synchronous transmission member 43, and the driven transmission member 44 to the width adjustment transmission assembly 30 located on the second side of the movable mechanism 201, thereby driving the second end of the movable mechanism 201.

[0084] In this embodiment, a single drive mechanism 41 can transmit power to two width-adjusting transmission components 30, thereby simultaneously transmitting power to both ends of the movable mechanism 201. This not only drives the movable mechanism 201 to move relative to the frame, but also ensures that both ends of the movable mechanism 201 are simultaneously subjected to force, resulting in good force balance. The synchronous movement of both ends of the mechanism ensures smooth operation, reduces jamming or angular deviations, and ultimately achieves stable and efficient adjustment of the width of the detection channel 100.

[0085] Optionally, there are multiple drive components 40, with each movable mechanism 201 corresponding to one drive component 40. The moving distance and moving speed of each movable mechanism 201 can be adjusted individually, thereby improving the accuracy and efficiency of the width adjustment of the detection channel 100.

[0086] Optionally, the drive mechanism 41 is a motor, the active transmission component 42 is a driving wheel, the synchronous transmission component 43 is a synchronous belt, and the driven transmission component 44 is a driven wheel. Exemplarily, the motor serves as the drive source, and its output shaft is connected to the first shaft of the driving wheel via a coupling. A synchronous belt is fitted between the driving wheel and the driven wheel to achieve synchronous transmission. The second shaft of the driving wheel is connected to a lead screw 32 on one side, and the third shaft of the driven wheel is connected to a lead screw 32 on the other side. The rotation of the motor's output shaft drives the driving wheel, synchronous belt, and driven wheel to rotate, thereby rotating the lead screws 32 at both ends of the movable mechanism 201. This causes the sliding seats 31 at both ends of the movable mechanism 201 to move along the y-direction, thus enabling the entire movable mechanism 201 to move along the y-direction.

[0087] Optionally, refer to Figure 7 Multiple drive components 40 are arranged on the same side of the rack in the y direction to achieve a compact layout and facilitate subsequent maintenance of the drive components 40.

[0088] Optionally, refer to Figure 7 The support device includes the dial 50 and drive assembly 40 described in the foregoing embodiments. The number of dials 50 is the same as the number of width-adjusting transmission assemblies 30, and the number of drive assemblies 40 is the same as the number of width-adjusting transmission assemblies 30.

[0089] The support device includes multiple dials 50 and multiple sets of drive components 40. One end of each lead screw 32 is connected to a dial 50, and the other end is connected to the drive mechanism 41. The lead screw 32 can rotate under the drive of the dials 50 or the drive mechanism 41. The operator can adjust the position of the movable mechanism 201 and thus the width of the detection channel 100 via electric control through the drive mechanism 41, which offers high efficiency. Alternatively, the operator can manually rotate the dials 50 to adjust the width of the detection channel 100, providing flexibility to meet different adjustment needs, such as fine-tuning or initial position correction.

[0090] For example, three sets of width-adjusting transmission assemblies 30 are provided on the first side base 11 and three sets of width-adjusting transmission assemblies 30 are provided on the second side base 11. Multiple sets of drive assemblies 40 and multiple dial wheels 50 are respectively arranged on both sides of the frame in the y-direction. Operators can choose to perform electric control or manual adjustment from one side or the other side of the frame according to the actual working environment and operating habits.

[0091] This application enables the layout of multiple inspection channels 100 in a single machine (single vision inspection device) within a small volume, and allows for adjustable width of each inspection channel 100 without obstructing the vision inspection devices 90 on both sides from inspecting the opposite sides of the product. It combines the advantages of double-sided inspection, multi-channel inspection, and small space occupation.

[0092] It is understandable that, based on the compact design of the visual inspection equipment in this application, the spacing between adjacent inspection channels 100 is reduced, and the spacing between the transmission lines connecting the visual inspection equipment and the previous or next workstation can also be reduced, thereby reducing the production line layout space.
