Description

Technical Field

[0001] This application relates to the field of automation technology, and more specifically, to an automatic detection mechanism. Background Technology

[0002] In the automated inspection of products such as mobile phone frames, to ensure continuous material supply, related technologies typically place multiple products side-by-side on the feeding device. However, to achieve the sequential transfer of multiple products, the moving mechanism must have a long stroke, resulting in the mechanism itself occupying too much space; at the same time, the feeding device to accommodate multiple products also needs to be correspondingly enlarged. These two factors combined result in the overall large size of the automated inspection mechanism, which is not conducive to equipment miniaturization and makes it difficult to apply in space-constrained working environments. Utility Model Content

[0003] This application provides an automatic detection mechanism to solve at least one of the technical problems mentioned above.

[0004] The automatic detection mechanism of this application includes a feeding device, a transfer device, and a detection device. The feeding device is located upstream of the transfer device, and the detection device is located on one side of the transfer device. The feeding device includes a transfer and circulation assembly, which includes: A placement table is provided with multiple material positions arranged in a circular sequence. The transfer device is used to move the product from one of the material positions to the testing equipment. Multiple transfer components are installed on the placement platform to work together to sequentially transfer the product to the multiple material locations.

[0005] The automatic detection mechanism provided in this application constructs a transfer and circulation component that can circulate and transfer products within a limited plane by setting up a placement platform with multiple material positions and cooperating with multiple transfer components. It replaces the traditional long-stroke parallel transfer with a cyclic progressive feeding method, which ensures the continuity of detection and feeding while reducing the stroke space required by the transfer device and the overall footprint of the feeding device. This is conducive to the miniaturization of the entire automatic detection mechanism, enabling it to be flexibly applied to space-constrained working environments.

[0006] In some embodiments, the material location includes a first loading location, a second loading location, a transfer location, and a feeding location. The first loading location and the second loading location are used to place the product during product loading. The transfer device is used to move the product at the feeding location to the detection device. The transfer assembly includes a first transfer assembly, a second transfer assembly, and a third transfer assembly. The first transfer assembly can move the product from the first loading location to the second loading location along a first direction. The second transfer assembly can move the product from the second loading location to the transfer location along a second direction, where the first direction intersects the second direction. The third transfer assembly can move the product from the transfer location to the feeding location along the opposite direction of the first direction.

[0007] In this way, by specifically defining the first loading position, the second loading position, the transfer position, and the feeding position, and configuring three transfer components to transfer the materials in different directions, the precise flow of products in sequence and back-and-forth within a limited plane is achieved, forming an efficient circular loading path, which is conducive to further optimizing the spatial layout.

[0008] In some embodiments, the transfer assembly includes a push block, a telescopic mechanism, and a drive member. The push block is slidably disposed on the placement platform. One end of the telescopic mechanism is connected to the placement platform, and the other end of the telescopic mechanism is connected to the push block. The drive member is mounted on the placement platform and is used to drive the telescopic mechanism to extend or retract.

[0009] Thus, by using a telescopic mechanism controlled by a drive component to drive the pusher, a smooth and reliable linear motion of the pusher is achieved, which is beneficial for precise control of the product's transfer position. At the same time, the telescopic mechanism has a stroke multiplication function, which helps to reduce the footprint of the transfer component.

[0010] In some embodiments, the feeding device further includes a main body, a lifting platform, and a feeding assembly. The lifting platform is slidably disposed on the main body in a vertical direction. The lifting platform is used to place a tray supporting the product. The feeding assembly is used to transfer the product on the tray to one or more of the feeding positions.

[0011] In this way, by setting up a main body with a lifting platform and a feeding component, the products in the pallet are automatically lifted and transferred to the transfer circulation component, which facilitates connection with the upstream warehousing or supply system and improves the automation and continuity of the entire feeding process.

[0012] In some embodiments, the feeding device further includes a clamping assembly mounted on the top of the main body. When the pallet is empty, the lifting platform slides to move the empty pallet to the clamping assembly so that the clamping assembly can clamp the empty pallet.

[0013] In this way, by setting a clamping component on the top of the main body and using a lifting platform to transport empty pallets, the empty pallets are automatically clamped and fixed, which facilitates subsequent removal or replacement, reduces manual intervention, and further improves automation efficiency.

[0014] In some embodiments, the feeding device further includes a fixing component, which includes a first cylinder and a fixing push block. The first cylinder is mounted on the placement platform, and the fixing push block is mounted on the drive end of the first cylinder. The first cylinder is used to drive the drive end to press against the tray to fix the tray.

[0015] In this way, by setting a fixed push block driven by the first cylinder, the pallet is automatically pressed and fixed on the lifting platform, preventing the pallet from shifting during lifting or loading, and ensuring the accuracy of the material picking position of the loading component.

[0016] In some embodiments, the fixing component further includes a slider and a limiting block. One end of the slider is connected to the driving end, and the other end is slidably disposed on the side wall of the cylinder. The slider is provided with a limiting part, and the limiting block is slidably disposed on the side wall of the cylinder along the moving direction of the driving end. When the driving end presses against the tray, the limiting part abuts against the limiting block.

[0017] In this way, by setting a slider connected to the drive end and a sliding limit block, and setting a limit part on the slider, the mechanical limit and locking of the pressing stroke of the fixed push block is realized, while the pressing stroke is adjustable, which is beneficial to adapting to more scenarios.

[0018] In some embodiments, the transfer device includes a main frame, a sliding frame, a second cylinder, and a transfer assembly. The main frame is provided with a detection material level, the transfer assembly is disposed on the sliding frame, the second cylinder is mounted on the main frame, and the second cylinder can drive the sliding frame to slide along a first direction on the main frame. The detection device detects the product on the detection material level, and the second cylinder and the transfer assembly work together to move the product from the material level to the detection material level.

[0019] In this way, by setting up a main frame, a sliding frame, a second cylinder, and multiple detection material positions, and cooperating with the transfer and circulation components, the step-by-step transfer of products between detection stations is realized, enabling a single detection device to detect multiple products sequentially, which is beneficial to improving the utilization rate of the detection equipment and the overall detection efficiency.

[0020] In some embodiments, the number of transfer components is four, and the transfer device further includes a positioning material position, a switching material position, and a transfer material position. The four transfer components are arranged on the sliding frame at preset intervals along a first direction. The positioning material position, the detection material position, the switching material position, and the transfer material position are arranged sequentially on the main frame at preset intervals along the first direction. The second cylinder works in conjunction with the transfer components to move the product from the material position to the transfer material position sequentially along the first direction.

[0021] In this way, by setting up four transfer components and multiple functional material positions such as positioning positions, the orderly flow and precise positioning of products before, during and after testing are realized, which facilitates the integration of complex testing procedures and improves the comprehensive testing capabilities of the mechanism.

[0022] In some embodiments, the automatic detection mechanism further includes a loading platform and a loading robot disposed downstream of the transfer assembly. The transfer assembly can move the product from the detection position to the loading platform, and the loading robot is used to move the product on the loading platform to the receiving area.

[0023] In this way, by setting up a feeding platform and feeding robot downstream of the transfer device, the automatic feeding and sorting collection of the tested products is realized, forming a complete closed-loop process from automatic feeding, cyclic transfer, testing to automatic feeding, reducing manual operation and improving overall production efficiency.

[0031] In the automated inspection of products such as mobile phone frames, to ensure continuous material supply, related technologies typically place multiple products side-by-side on the feeding device. However, to achieve the sequential transfer of multiple products, the moving mechanism must have a long stroke, resulting in the mechanism itself occupying too much space; at the same time, the feeding device to accommodate multiple products also needs to be correspondingly enlarged. These two factors combined result in the overall large size of the automated inspection mechanism, which is not conducive to equipment miniaturization and makes it difficult to apply in space-constrained working environments.

[0032] Please see Figure 1 and Figure 2The automatic detection mechanism 1000 of this application includes a feeding device 100, a transfer device 200, and a detection device 300. The feeding device 100 is located upstream of the transfer device 200, and the detection device 300 is located on one side of the transfer device 200. The feeding device 100 includes a transfer circulation component 10, which includes a placement platform 11 and multiple transfer components 13. The placement platform 11 is provided with multiple material positions 12, which are arranged in a circular sequence. The transfer device 200 is used to move the product of one of the material positions 12 to the detection device 300. The multiple transfer components 13 are installed on the placement platform 11 and work together to transfer the product sequentially on the multiple material positions 12.

[0033] The automatic detection mechanism 1000 provided in this application, by setting up a placement platform 11 with multiple material positions 12 and cooperating with multiple transfer components 13, constructs a transfer circulation component 10 that can circulate and transfer products within a limited plane. It replaces the traditional long-stroke parallel transfer with a cyclic progressive feeding, ensuring the continuity of detection and feeding while reducing the stroke space required by the transfer device 200 and the overall footprint of the feeding device 100. This is conducive to the miniaturization of the entire automatic detection mechanism 1000, enabling it to be flexibly applied to space-constrained working environments.

[0034] For details, please refer to Figures 1 to 4 In this embodiment of the application, the feeding device 100 is located upstream of the transfer device 200. The distance between the two is determined according to the maximum transfer stroke of the transfer device 200. It is generally controlled within the range where the transfer device 200 can stably transfer products, so as to avoid unstable transfer due to excessive distance or waste of space due to excessive distance.

[0035] In this embodiment, the testing device 300 is disposed on one side of the travel of the transfer device 200, so that the transfer device 200 can move the product from the feeding device 100 to the testing device 300 and then remove it from the testing device 300.

[0036] In this embodiment, multiple material positions 12 are arranged in a ring. For example, when there are four material positions 12, they can be arranged into a rectangle; when there are five material positions 12, they can be arranged into a pentagon; and when there are six material positions 12, they can be arranged into a hexagon. The product is placed on one of the material positions 12 and is sequentially transferred across the multiple material positions 12 under the drive of multiple transfer components 13.

[0037] Please see Figure 1In some embodiments, the material position 12 includes a first loading position 121, a second loading position 122, a transfer position 123, and a feeding position 124. The first loading position 121 and the second loading position 122 are used to place products when loading products, and the transfer device 200 is used to move the products at the feeding position 124 to the detection device 300. The transfer component 13 includes a first transfer component, a second transfer component, and a third transfer component. The first transfer component can move the products from the first loading position 121 to the second loading position 122 along a first direction. The second transfer component can move the products from the second loading position 122 to the transfer position 123 along a second direction, where the first direction and the second direction intersect. The third transfer component can move the products from the transfer position 123 to the feeding position 124 along the opposite direction of the first direction.

[0038] In this way, by specifically defining the first loading position 121, the second loading position 122, the transfer position 123 and the feeding position 124, and configuring three transfer components 13 to transfer the products in different directions, the precise flow of products in sequence and back-and-forth within a limited plane is realized, forming an efficient circular loading path, which is conducive to further optimizing the spatial layout.

[0039] Specifically, in this embodiment, the first direction is perpendicular to the second direction, and the four material positions, namely the first feeding position 121, the second feeding position 122, the transfer position 123 and the feeding position 124, are evenly distributed in a rectangular frame clockwise. Specifically, the first feeding position 121 and the second feeding position 122 are located close to the feeding device 100, and the feeding position 124 is located close to the transfer device 200.

[0040] In some embodiments, the number of the four material stations 12, namely the first feeding station 121, the second feeding station 122, the transfer station 123, and the feeding station 124, can be adjusted according to the actual production needs of product transfer efficiency. For example, in scenarios with a large product demand, the number of feeding stations can be increased to three, and the position distribution of the transfer station 123 and the feeding station 124 can be adjusted accordingly to further improve the feeding speed.

[0041] In this embodiment, the first transfer component, the second transfer component, and the third transfer component are installed below the placement table 11. The first transfer component can transfer the product from the first loading position 121 to the second loading position 122. The second transfer component is at a 90-degree angle to the first transfer component and is used to transfer the product from the second loading position 122 to the intermediate transfer position 123. The third transfer component is at a 90-degree angle to the second transfer component, but its movement direction is opposite to that of the first transfer component, so that the product can smoothly return from the intermediate transfer position 123 to the feeding position 124, forming a complete loop path.

[0042] Please see Figure 1 and Figure 5In some embodiments, the transfer assembly 13 includes a push block 131, a telescopic mechanism 132, and a drive member 133. The push block 131 is slidably disposed on the placement platform 11. One end of the telescopic mechanism 132 is connected to the placement platform 11, and the other end of the telescopic mechanism 132 is connected to the push block 131. The drive member 133 is mounted on the placement platform 11 and is used to drive the telescopic mechanism 132 to extend or retract.

[0043] Thus, by using the telescopic mechanism 132 controlled by the drive component 133 to drive the push block 131, the push block 131 achieves smooth and reliable linear motion, which is conducive to precise control of the product transfer position. At the same time, the telescopic mechanism 132 has a stroke multiplication function, which is conducive to reducing the footprint of the transfer component 13.

[0044] Specifically, in this embodiment, the telescopic mechanism 132 adopts an X-shaped linkage structure. The rear end of the X-shaped linkage structure has a rear connection point, which is connected to the placement platform 11. The front end of the X-shaped linkage structure has a front connection point, which is connected to the push block 131. The X-shaped linkage structure has a power connection point near the rear end. The driving end of the driving member 133 acts on the power connection point to drive the telescopic movement of the X-shaped linkage structure.

[0045] Furthermore, in the embodiments of this application, the driving member 133 is a linear driving member 133, such as a cylinder, a linear motor, etc. The driving end of the linear driving member 133 is connected to the telescopic mechanism 132 to drive the telescopic mechanism 132 to extend or retract.

[0046] In some embodiments, the telescopic mechanism 132 and the drive component 133 may also employ a multi-stage telescopic cylinder. Compared to a traditional single-stage cylinder, a multi-stage telescopic cylinder has a shorter length in the retracted state, which can further reduce the footprint of the transfer assembly 13, while providing sufficient stroke in the extended state to complete product transfer. Its telescopic speed can be precisely controlled by an air circuit regulating valve to adapt to the product transfer needs of different weights and sizes. In some embodiments, the push block 131 is designed as a groove structure that adapts to the shape of the product. For example, when the product is rectangular, the contact surface of the push block 131 is set as a rectangular groove. The depth and width of the groove are slightly greater than the height and width of the product to ensure that the product will not slip off the push block 131 during the transfer process, thereby improving the stability of the transfer.

[0047] Please see Figure 3 and Figure 4 In some embodiments, the feeding device 100 further includes a main body 14, a lifting platform 15, and a feeding assembly 16. The lifting platform 15 is slidably disposed on the main body 14 in a vertical direction and is used to place a pallet supporting the product. The feeding assembly 16 is used to transfer the product on the pallet to one or more of the material positions 12.

[0048] Thus, by setting up a main body 14 with a lifting platform 15 and a feeding component 16, the products in the pallet are automatically lifted and transferred to the transfer circulation component 10, which facilitates connection with the upstream warehousing or supply system and improves the automation and continuity of the entire feeding process.

[0049] Specifically, in some embodiments, the main body 14 is designed as a frame structure, with the frames connected by reinforcing ribs. The number of reinforcing ribs is determined according to the height of the main body 14 and the load-bearing requirements. For example, a transverse reinforcing rib can be set every 500mm between the four columns of the main body 14, and longitudinal reinforcing ribs can be set at the bottom and top of the columns to improve the overall rigidity of the main body 14 and prevent the main body 14 from deforming during the movement of the lifting platform 15.

[0050] Furthermore, the lifting platform 15 is connected to the main body 14 via a linear guide rail. The linear guide rail is a high-precision ball linear guide rail, which has the characteristics of smooth movement, high precision and low wear. It can ensure the vertical movement accuracy of the lifting platform 15 and prevent the product from falling due to the tilt of the lifting platform 15.

[0051] In some embodiments, the lifting platform 15 may be made of welded steel plate with anti-slip rubber pads on its surface. The anti-slip rubber pads can not only increase the friction between the product and the lifting platform 15 and prevent the product from sliding during the lifting process, but also play a buffering role to reduce collision damage between the product and the lifting platform 15.

[0052] In some embodiments, the feeding component 16 adopts a robotic arm structure, with a gripper or suction cup installed at the end of the robotic arm. The appropriate material picking method can be selected according to the material and shape of the product. For example, suction cup is used to pick up materials for easily deformable plastic products, while gripper is used to pick up materials for metal products with good rigidity.

[0053] Please see Figure 4 In some embodiments, the feeding device 100 further includes a clamping component 17, which is mounted on the top of the main body 14. When the pallet is empty, the lifting platform 15 slides to move the empty pallet to the clamping component 17 so that the clamping component 17 can clamp the empty pallet.

[0054] Thus, by setting a clamping component 17 on the top of the main body 14 and using the lifting platform 15 to transport empty pallets, the empty pallets are automatically clamped and fixed, which facilitates subsequent removal or replacement, reduces manual intervention, and further improves automation efficiency.

[0055] Specifically, in this embodiment, the clamping assembly 17 consists of two clamping cylinders 171 arranged opposite to each other and clamping plates 172 disposed at the driving ends of the two clamping cylinders 171. The clamping cylinders 171 are double-acting cylinders, which have bidirectional driving force and can realize the clamping and releasing actions of the clamping claws. They are fast in action and quick in response, and can clamp and fix empty pallets in a timely manner.

[0056] In this embodiment, the clamping cylinders 171 are installed on both sides of the top of the main body 14. The two clamping cylinders 171 are symmetrically arranged to ensure that the clamping force on the empty pallet is uniform and to prevent the empty pallet from tilting during the clamping process.

[0057] In some embodiments, a rubber pad may be provided on the clamping plate 172. The surface of the rubber pad is provided with anti-slip texture to increase the friction between the clamping assembly 17 and the empty pallet, ensuring a firm clamping and preventing the clamping plate 172 from causing squeezing damage to the empty pallet.

[0058] In this embodiment, after all products on the lifting platform 15 are transferred to the transfer circulation component 10, the lifting platform 15 slides vertically upward via a linear guide rail, causing the empty pallet to rise synchronously. When the empty pallet rises to a position flush with the clamping plate 172, the lifting platform 15 stops moving. At this time, the clamping cylinder 171 drives the clamping plate 172 to move towards the center until the clamping plate 172 tightly clamps both sides of the empty pallet, completing the clamping and fixing of the empty pallet. In subsequent processing, the clamped and fixed empty pallet can be removed manually or by a robotic arm and replaced with a new pallet filled with products. The entire process does not require manual intervention in the positioning and fixing of the empty pallet, reducing manual operation steps and further improving the automation efficiency of the loading device 100.

[0059] In this embodiment, the clamping assembly 17 is also provided with a position sensor. The position sensor is installed on the main body 14. When the empty pallet rises to a position flush with the clamping plate 172, the position sensor will send a signal, and the control system will control the clamping plate 172 to clamp the empty pallet, and then control the lifting platform 15 to descend until the lifting platform 15 moves to the unloading height.

[0060] Please see Figure 3 In some embodiments, the feeding device 100 further includes a fixing component 18, which includes a first cylinder 181 and a fixing push block 182. The first cylinder 181 is mounted on the placement platform 11, and the fixing push block 182 is mounted on the drive end of the first cylinder 181. The first cylinder 181 is used to drive the drive end to press against the tray to fix the tray.

[0061] Thus, by setting a fixed pusher 182 driven by the first cylinder 181, the pallet is automatically pressed and fixed on the lifting platform 15, preventing the pallet from shifting during lifting or loading, and ensuring the accuracy of the material picking position of the loading component 16.

[0062] Specifically, in this embodiment, when the lifting platform 15 raises the pallet to the designated loading position, the control system sends a signal, the first cylinder 181 is ventilated, and the fixed push block 182 is driven to move toward the pallet until the fixed push block 182 presses tightly against the side of the pallet, fixing the pallet on the lifting platform 15.

[0063] In this embodiment, the first cylinder 181 is mounted on the edge of the placement platform 11 via a cylinder bracket. The cylinder bracket is made of angle steel and is fixedly connected to the placement platform 11 by bolts. The height of the cylinder bracket can be adjusted according to the height of the tray to ensure that the fixed push block 182 can accurately act on the side of the tray.

[0064] In some embodiments, the first cylinder 181 in the fixing assembly 18 is a single-acting cylinder, which has the characteristics of simple structure, low cost and convenient maintenance. When air is supplied, it drives the fixing push block 182 to move towards the tray to achieve pressing and fixing of the tray. When air is cut off, it is reset by spring to make the fixing push block 182 leave the tray, which facilitates the replacement of the tray.

[0065] In some embodiments, the fixing push block 182 is made of a material with good elasticity and wear resistance, such as polyurethane, which can deform to a certain extent when in contact with the pallet, increasing the contact area with the pallet and improving the fixing effect, while avoiding scratches on the pallet surface.

[0066] In some embodiments, the first cylinder 181 can be replaced by an electric push rod, which has the advantages of higher control precision and convenient thrust adjustment. It is suitable for scenarios with high requirements for pallet fixing force. By adjusting the output thrust of the electric push rod, it can be adapted to pallets of different materials and thicknesses, further expanding the applicability of the fixing component 18.

[0067] Please see Figure 6 In some embodiments, the fixing component 18 further includes a slider 183 and a limiting block 184. One end of the slider 183 is connected to the driving end, and the other end is slidably disposed on the side wall of the cylinder. The slider 183 is provided with a limiting part 1831. The limiting block 184 is slidably disposed on the side wall of the cylinder along the moving direction of the driving end. When the driving end presses against the tray, the limiting part 1831 abuts against the limiting block 184.

[0068] Thus, by setting a slider 183 connected to the drive end and a sliding limit block 184, and setting a limit part 1831 on the slider 183, the mechanical limit and locking of the pressing stroke of the fixed push block 182 is realized, while the pressing stroke is adjustable, which is beneficial to adapting to more scenarios.

[0069] Specifically, in this embodiment, the slider 183 is elongated, with a mounting portion at one end connected to the cylinder sidewall, and a limiting portion 1831 at the other end, so that the slider 183 is generally H-shaped. The limiting block 184 is U-shaped, with its opening facing the cylinder, and is mounted on the cylinder sidewall, thereby forming a sliding channel with the cylinder. The slider 183 is slidably disposed in the sliding channel, and the limiting portion 1831 extends out from the other end of the sliding channel.

[0070] In this embodiment of the application, elongated slots are provided on both sides of the limiting block 184 along the moving direction of the drive end, and the limiting block 184 is detachably installed on the side wall of the cylinder by fasteners passing through the elongated slots. Thus, the movement stroke of the fixed push block 182 can be limited by changing the installation position of the limiting block 184, and the selection range of the stroke of the first cylinder 181 can be expanded.

[0071] Please see Figure 6 In some embodiments, the transfer device 200 includes a main frame 210, a sliding frame 220, a second cylinder 230, and a transfer assembly 240. The main frame 210 is provided with a detection material level 252. The transfer assembly 240 is disposed on the sliding frame 220. The second cylinder 230 is mounted on the main frame 210. The second cylinder 230 can drive the sliding frame 220 to slide along a first direction on the main frame 210. The detection device 300 detects the product on the detection material level 252. The second cylinder 230 and the transfer assembly 240 work together to move the product from the material level 12 to the detection material level 252.

[0072] Thus, by setting up the main frame 210, sliding frame 220, second cylinder 230 and multiple detection material positions 252, and cooperating with the transfer circulation component 10, the step-by-step transfer of products between detection stations is realized, so that a single detection device 300 can detect multiple products in sequence, which is conducive to improving the utilization rate and overall detection efficiency of the detection device 300.

[0073] Specifically, in this embodiment, the sliding frame 220 and the main frame 210 are connected by a linear guide rail. The linear guide rail is a heavy-duty ball linear guide rail, which has a strong load-bearing capacity and can withstand the weight of the sliding frame 220 and the transfer component 240, while ensuring that the sliding frame 220 slides smoothly on the main frame 210 along the first direction.

[0074] In this embodiment, the second cylinder 230 is mounted on one end of the main frame 210 via a cylinder seat. The cylinder seat and the main frame 210 are fixedly connected by bolts. The piston of the cylinder is connected to the sliding frame 220. When the second cylinder 230 is ventilated, the piston drives the sliding frame 220 to slide along the linear guide rail.

[0075] In this embodiment of the application, the transfer assembly 240 is installed on the top of the sliding frame 220. Each transfer assembly 240 includes a lifting cylinder and a pneumatic gripper or pneumatic suction cup. The lifting cylinder drives the pneumatic gripper or pneumatic suction cup to move in the vertical direction to realize the picking and placing of products.

[0076] In this embodiment, when there is a product on the feeding position 124 of the transfer circulation component 10, the second cylinder 230 drives the sliding frame 220 to move, so that the transfer component 240 is aligned with the feeding position 124. The lifting cylinder drives the pneumatic gripper to descend, clamp the product and then rise. Then the second cylinder 230 drives the sliding frame 220 to move towards the detection position 252, transferring the product to the detection position 252. At the same time, the transfer component 13 continues to transfer the next product to the feeding position 124, realizing continuous transfer of products.

[0077] In some embodiments, the second cylinder 230 is a rodless cylinder. Compared with traditional rod cylinders, rodless cylinders have the advantages of long stroke and small installation space. They can achieve long-distance sliding of the sliding frame 220 within the limited length of the main frame 210, thus meeting the product transfer requirements from material level 12 to detection material level 252.

[0078] In some embodiments, the bottom of the main frame 210 is provided with adjusting pads. The adjusting pads are made of rubber, which not only play a shock absorption role and reduce the impact of vibration during the operation of the transfer device 200 on the detection device 300, but also allow the main frame 210 to be kept horizontal by rotating the height of the pads, thus ensuring the sliding accuracy of the sliding frame 220.

[0079] Please see Figure 7 and Figure 8 In some embodiments, the number of transfer components 240 is four. The transfer device 200 also includes a positioning material position 251, a switching material position 253, and a transfer material position 254. The four transfer components 240 are arranged on the sliding frame 220 at a preset interval along the first direction. The first transfer material position 251, the positioning material position 251, the detection material position 252, the switching material position 253, and the transfer material position 254 are arranged sequentially on the main frame 210 at a preset interval along the first direction. The second cylinder 230 works together with the transfer components 240 to move the product from the material position 12 to the transfer material position 254 sequentially along the first direction.

[0080] In this way, by setting up four transfer components 240 and multiple functional material positions such as positioning material position 251, the orderly flow and precise positioning of products before, during and after testing are realized, which facilitates the integration of complex testing procedures and improves the comprehensive testing capabilities of the mechanism.

[0081] Specifically, in this embodiment, the positioning material position 251, the detection material position 252, the switching material position 253, and the transfer material position 254 are arranged sequentially on the main frame 210 along the first direction at the same preset interval. The number of transfer components 240 is set to four. The four transfer components 240 are evenly installed on the sliding frame 220 along the first direction at the same preset interval, ensuring that the four transfer components 240 can accurately correspond to the positioning material position 251, the detection material position 252, the switching material position 253, and the transfer material position 254 respectively, so as to realize the precise transfer of products.

[0082] In this embodiment, the positioning material position 251 is used to achieve precise positioning of the product, providing an accurate detection benchmark for subsequent testing. The detection probe of the testing equipment 300 is directly facing the detection material position 252. When the product is transferred to the detection material position 252, the detection probe detects the product. During the detection process, other transfer components 240 can simultaneously transfer products, improving detection efficiency. The switching material position 253 is used to classify products according to the detection results. If the product passes the test, the transfer component 240 transfers it to the intermediate material position 254. If the product fails the test, it is transferred to the non-conforming product collection area. The switching material position 253 also serves as a switch between raw and cooked materials. That is, with the switching material position 253 as the boundary, products before the switching material position 253 are raw materials, and products after the switching material position 253 are cooked materials. The intermediate material position 254 is located on the side away from the intermediate circulation component 10 and is used to temporarily store products that have passed the test, waiting for the subsequent unloading process.

[0083] In this embodiment, the second cylinder 230 drives the sliding frame 220 to move along a first direction, causing four transfer components 240 to move synchronously. The first transfer component 240 transfers the product from the feeding position 124 to the positioning position 251; the second transfer component 240 transfers the product from the positioning position 251 to the detection position 252; the third transfer component 240 transfers the product from the detection position 252 to the switching position 253; and the fourth transfer component 240 transfers the qualified product from the switching position 253 to the intermediate position 254, thus realizing the sequential movement of products. This not only achieves the orderly flow of products before, during, and after detection, but also integrates complex processes such as positioning, detection, and classification, improving the comprehensive detection capabilities of the mechanism and making it suitable for scenarios with high product detection requirements.

[0084] Please see Figure 7 and Figure 9In some embodiments, the automatic detection mechanism 1000 further includes a loading platform 400 and a loading robot 500 disposed downstream of the transfer assembly 240. The transfer assembly 240 can move products from the detection position 252 to the loading platform 400, and the loading robot 500 is used to move products on the loading platform 400 to the receiving area.

[0085] Thus, by setting up a feeding platform 400 and a feeding robot 500 downstream of the transfer device 200, the automatic feeding and sorting collection of the inspected products is realized, forming a complete closed-loop process from automatic feeding, cyclic transfer, inspection to automatic feeding, reducing manual operation and improving overall production efficiency.

[0086] Specifically, in this embodiment, the surface of the unloading platform 400 is provided with an unloading position 410. The transfer component 240 moves the inspected product from the transfer position 254 to the unloading position 410. At this time, the unloading robot 500 moves the product on the unloading position 410 to the tray in the receiving area.

[0087] In this embodiment, there are two unloading positions 410, which are arranged parallel to each other in opposite directions on the unloading platform 400. The unloading platform 400 is rotated, and the transfer component 240 moves the inspected product from the transfer position 254 to one of the unloading positions 410. The unloading robot 500 then unloads the product from the other unloading position 410. Specifically, when the transfer component 240 returns, the unloading platform 400 rotates 180 degrees to rotate the product to the side of the unloading robot 500 and transfers the empty unloading position 410 to the side of the transfer component 240.

[0088] In this embodiment, since the product needs to be rotated 180 degrees when it is unloaded and moved onto the pallet, the unloading platform 400 is provided with a unloading groove on its side along the length direction perpendicular to the unloading position 410. The unloading robot 500 can grip the product from below the unloading platform 400 and through the unloading groove, and rotate 180 degrees during unloading.

[0089] In some embodiments, the unloading robot 500 is a six-axis multi-joint industrial robot. This type of robot has the advantages of high flexibility and high motion precision, and can accurately complete the transfer of products from the unloading table 400 to the receiving area. The robot's end effector adopts a quick-change structure, which can quickly replace vacuum suction cups or mechanical grippers according to product characteristics.
