Description

Technical Field

[0001] This invention relates to the field of power supply manufacturing technology, specifically to an NG rework and automatic board return device. Background Technology

[0002] In the production and testing lines of industrial power supply products such as power supplies for computer rooms and industrial automation equipment, after processes such as aging tests, load tests, and functional verification, unqualified (NG) power supply products are screened out. These power supply products are high-value, heavy, and have external interfaces and precision internal components. They need to be uniformly scanned and registered with product serial numbers and defect information before being sent to the rework workshop for repair. The processing efficiency and traceability accuracy of NG power supplies directly affect the overall production line cycle and the full life cycle management of high-value power supplies. It is an indispensable process in the production of industrial power supplies.

[0003] Currently, the handling of NG (no good) power supplies on production lines mostly relies on manual operation combined with simple planar conveyor systems: detected defective power supplies are manually removed from the material area of ​​the production line, their product information is manually scanned and registered, and then transported to the rework workshop via a transfer cart or planar conveyor line. Some more automated production lines use independent planar conveyor lines to transport NG products, but this function is fragmented and has many overall shortcomings. First, the testing station on the industrial power supply production line has a fast cycle time. The power supply products are large in size and weight, and the labor intensity of manual handling, barcode scanning, and transportation is high. The processing speed is difficult to match the high cycle time of the production line, which can easily cause NG power supplies to accumulate in the material area. In addition, manual barcode scanning is prone to missed scanning and incorrect scanning, resulting in incorrect registration of power supply serial numbers and defect information. Subsequent rework and quality traceability are difficult, which affects the full life cycle management of high-value power supplies.

[0004] Secondly, industrial power supplies have metal casings, external terminals, and internal precision electronic components, making them quite heavy. During manual handling and transportation, they are prone to being dropped, bumped, or having their interfaces damaged. This not only causes secondary damage to the product, increasing the difficulty and cost of rework, but the weight of the power supply also poses a safety hazard, as it can easily cause injuries to operators during transportation.

[0005] Third, most existing NG conveying equipment is in a planar layout, with the functions of feeding, conveying, scanning, and returning the plate distributed across multiple independent devices. The overall equipment occupies a large space, making it difficult to adapt to the needs of a compact workshop layout, especially in scenarios where the power supply to the machine room is limited or where the space for the renovation of an old production line is limited. Furthermore, planar conveying cannot utilize vertical space, resulting in low workshop space utilization.

[0006] Fourth, existing equipment cannot automatically complete the entire process of loading and grabbing, scanning and registering, lifting and transferring, docking and returning the board. The power supply is heavy, and manual loading and unloading is labor-intensive. It requires dedicated personnel to perform board placement, board connection and scanning operations, resulting in high labor costs and making it impossible to achieve unmanned automatic operation of NG power supply processing.

[0007] Fifth, existing equipment cannot automatically connect the return conveyor belt between the production line material area and the rework workshop, requiring manual transfer and handling. This results in a disjointed process, low efficiency in returning NG power supplies, directly impacting the repair progress in the rework workshop and extending the production and delivery cycle of high-value power supplies.

[0008] In summary, existing NG power supply handling methods and equipment suffer from several technical shortcomings, including high reliance on manual labor, high labor intensity, low processing efficiency, high error rates, potential product damage and safety hazards, low integration, large footprint, insufficient automation, and poor process coordination. These limitations fail to meet the demands of industrial power supply production lines for efficient, automated, and safe handling of NG products. Therefore, there is an urgent need to develop an NG rework and automatic return system that integrates automatic feeding, transfer, conveying, barcode scanning and registration, and lifting and returning of the board. This system would achieve fully automated NG power supply processing, improve processing efficiency, reduce labor costs and product damage, save workshop space, and ensure operational safety. Summary of the Invention

[0009] The purpose of this invention is to provide an NG rework and automatic board return device to solve the problems of existing NG product rework processing equipment, such as the dispersed processing steps, discontinuous product conveying process, and large horizontal space occupation of the equipment.

[0010] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: This invention discloses an NG rework and automatic board return device, comprising: The rack is constructed as a cabinet structure, and the rack has cavities for installing other components; The feeding and transferring mechanism is located at the top of the cavity.

The second lifting mechanism is located on both sides of the NG inspection mechanism. The second lifting mechanism includes a second track and a second conveying platform. The second conveying platform is used to receive the scanned products conveyed by the NG inspection mechanism and drive the products to move downward along the second track. The return plate mechanism is located below the NG inspection mechanism. The return plate mechanism includes a second conveyor belt, which is connected to the return plate conveyor belt. After the second conveyor platform moves along the second track to the lower end of the second track, it conveys the product to the second conveyor belt. The second conveyor belt conveys the product to the return plate conveyor belt, and the return plate conveyor belt conveys the product to the rework workshop.

[0011] Furthermore, the feeding and transplanting mechanism also includes a first mounting plate, a third track, and a fourth track. The fourth track is connected to the inner wall of the cavity. The first mounting plate is provided with a first guide block, which is slidably connected to the fourth track. The third track is provided on the first mounting plate, and the gripping device is slidably connected to the third track. The first mounting plate is also provided with a slot corresponding to the gripping device.

[0012] Furthermore, the gripping device includes a mounting frame, a mechanical claw, and an electromagnetic chuck. The mechanical claw is connected to one end of the mounting frame, and the electromagnetic chuck is located at the bottom of the mechanical claw. The mounting frame is slidably connected to a third track. When the electromagnetic chuck is energized, it generates magnetic force to adhere to the magnetic block of the product.

[0013] Furthermore, the gripping device also includes a movable plate, a fifth track on the mechanical claw, a second guide block on the movable plate, and the second guide block slidably connected to the fifth track; an electromagnetic chuck is located on the movable plate, a buffer assembly is provided on the electromagnetic chuck, and the magnetic chuck block of the product is provided with a connection hole corresponding to the buffer assembly.

[0014] Furthermore, the buffer assembly includes a connecting frame, a connecting rod, and a support rod. The connecting frame is C-shaped, and a through hole is provided at the bottom of the connecting frame. The connecting rod passes through the through hole and can move up and down along the through hole. The support rod is connected to the top of the connecting frame. The connecting rod and the support rod are opposite to each other and spaced apart to form a clearance space between the connecting rod and the support rod for the connecting rod to move upward. The side wall of the connecting rod is provided with a protrusion made of elastic material, which is used to elastically abut against the inner wall of the connecting hole.

[0015] Furthermore, the conveying mechanism also includes a second mounting plate, which is located below the first mounting plate. There are two sets of first conveyor belts, which are respectively located on both sides of the second mounting plate. A first motor is provided on the second mounting plate, which provides power to the two sets of first conveyor belts.

[0016] Furthermore, a third conveyor belt is provided on the first conveyor platform, and a fourth conveyor belt is provided on the second conveyor platform. Both the third and fourth conveyor belts are capable of conveying products in opposite directions.

[0017] Furthermore, the NG inspection mechanism also includes a third mounting plate, a material carrier block, and a movable block. The third mounting plate is equipped with a second cylinder, the material carrier block is located on the piston rod of the second cylinder, the barcode scanning camera is located above the third mounting plate, and the material carrier block is located below the barcode scanning camera. A crossbeam is provided on the inner wall of the cavity, the movable block is slidably connected to the crossbeam, and the barcode scanning camera is located on the movable block.

[0018] Furthermore, the NG rework and automatic return equipment also includes a one-way guide device, which includes a mounting base, an abutment rod, and a roller. The mounting base is provided with a connecting groove, and the abutment rod is rotatably connected to the connecting groove via a rotating shaft. A torsion spring is provided on the rotating shaft, and a limit rod is provided in the connecting groove. The limit rod abuts against one end of the abutment rod, and the abutment rod can rotate in a direction that avoids the normal conveying path of the product. The limit rod is used to restrict the abutment rod from rotating in the opposite direction. The roller is located at the top of the abutment rod.

[0019] Furthermore, the one-way guiding device also includes a first cylinder and a connecting plate. The first cylinder is mounted on a first mounting plate, a second mounting plate, a third mounting plate, a first conveying platform, or a second conveying platform via the connecting plate. The output end of the first cylinder is connected to the mounting base to drive the mounting base to lift and lower.

[0020] The advantages of this invention over the prior art are as follows: This invention integrates a feeding and transferring mechanism, a conveying mechanism, a first lifting mechanism, an NG detection mechanism, a second lifting mechanism, and a return plate mechanism within a frame, forming a continuous product processing path from the material area through feeding and grabbing, horizontal conveying, first lifting, barcode scanning and warehousing, second lifting, and return plate conveying. This reduces manual transfer of products between different equipment and processes, improves the efficiency of connection between processing steps, and increases the automation level of NG product rework. Simultaneously, the first and second lifting mechanisms convey products longitudinally along the frame, allowing each mechanism to be integrated and arranged using the frame's longitudinal space, reducing the horizontal space occupied by the equipment and improving workshop space utilization. The barcode scanning camera can scan and register product codes during product conveying, ensuring product information corresponds to the actual product and improving the accuracy and continuity of NG product processing and return plate conveying.

Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0043] like Figure 1 and Figure 2 As shown, an NG rework and automatic board return device includes a frame 100, a feeding and transfer mechanism 200, a conveying mechanism 300, a first lifting mechanism 400, an NG detection mechanism 500, a second lifting mechanism 600, and a board return mechanism 700.

[0044] The frame 100 is constructed as a cabinet structure, with a cavity on the frame 100 for mounting other components. A fan assembly is also provided on the frame 100 for cooling the electrical components within the cavity. A loading and transferring mechanism 200 is located at the top of the cavity. The loading and transferring mechanism 200 includes a gripping device that can move horizontally relative to the frame 100 to grip a designated product 800 located in a material area on one side of the frame 100. This designated product 800 is a defective product requiring rework. A conveying mechanism 300 is located on one side of the loading and transferring mechanism 200. The conveying mechanism 300 includes a first conveyor belt 302. After the gripping device grips the designated product 800, it places the product 800 onto the conveying mechanism 302. The first conveyor belt 302 moves the product 800 towards one side of the cavity. A first lifting mechanism 400 is located at the transport end of the first conveyor belt 302. The first lifting mechanism 400 includes… The system includes a first track 401 and a first conveying platform 402. The first track 401 is arranged longitudinally, and the first conveying platform 402 receives the product 800 conveyed from the first conveyor belt 302 and moves downward along the first track 401. An NG inspection mechanism 500 is located below the conveying mechanism 300 and receives the product 800 from the first lifting mechanism 400. The NG inspection mechanism 500 includes a barcode scanning camera 504, which is used to scan the product code of the product 800 on the NG inspection mechanism 500 for warehousing processing. The first lifting mechanism 400 and the second lifting mechanism 600 are respectively located on both sides of the NG inspection mechanism 500. The second lifting mechanism 600 includes a second track 601 and a second conveying platform 602. The second conveying platform 602 receives the product 800 that has been scanned from the NG inspection mechanism 500 and moves downward along the second track 601.

[0045] like Figure 14 As shown, the return plate mechanism 700 is located below the NG inspection mechanism 500. The return plate mechanism 700 includes a fourth mounting plate 701 and a second conveyor belt 702. The second conveyor belt 702 is located on the fourth mounting plate 701 and is connected to the return plate conveyor belt. After the second conveying platform 602 moves the product 800 to the lower end of the second track 601, it transports the product 800 to the second conveyor belt 702. The second conveyor belt 702 transports the product 800 to the return plate conveyor belt, and the return plate conveyor belt transports the product 800 to the rework workshop.

[0046] During operation, the NG power supplies screened by the production line are placed in the material area on one side of the frame 100. The gripping device moves horizontally above the material area, grabs the NG power supply, and moves it above the conveyor mechanism 300, placing the product 800 on the first conveyor belt 302. The first conveyor belt 302 moves the NG power supply, sending the product 800 onto the first conveyor platform 402 of the first lifting mechanism 400. After receiving the product 800, the first conveyor platform 402 moves downward along the first track 401, sending the product 800 to the NG detection mechanism 500 below. The barcode scanning camera 50 on the NG detection mechanism 500... 4. The product code on the surface of product 800 is automatically scanned to complete the information registration and warehousing of NG product 800. After confirming that the information is correct, NG product 800 is sent to the second conveyor platform 602 of the second lifting mechanism 600. After receiving the scanned product 800, the second conveyor platform 602 continues to move downward along the second track 601 to the bottom and outputs product 800 to the second conveyor belt 702 of the return board mechanism 700. The second conveyor belt 702 directly transports product 800 to the external return board conveyor belt, and finally automatically sends NG product 800 into the rework workshop to complete the entire NG power supply rework and return process.

[0047] like Figure 5 As shown, specifically, the feeding and transplanting mechanism also includes a first mounting plate 203, a third track 204, and a fourth track 205. The fourth track 205 is longitudinally connected to the inner wall of the cavity. The first mounting plate 203 is provided with a first guide block 206, which is slidably connected to the fourth track 205. The third track 204 is provided on the first mounting plate 203, and the gripping device is slidably connected to the third track 204. The first mounting plate 203 is also provided with a slot corresponding to the gripping device. The first mounting plate 203 can move longitudinally along the fourth track 205, thereby driving the gripping device to adjust its overall longitudinal height. This allows the gripping device to adapt to NG products 800 with different stacking heights in the material area, avoiding the inability to grip products 800 due to changes in the number of stacking layers. The third track 204 is set horizontally, and the gripping device can move horizontally along the third track 204, extending from inside the cavity to above the material area to grip products 800. After gripping, it retracts above the cavity, completing the material handling action. The slot provides movement space for the gripping device, avoiding structural interference between the gripping device and the first mounting plate 203 during movement.

[0048] like Figure 3 and Figure 5As shown, the gripping device includes a mounting frame 207, a mechanical gripper 201, and an electromagnetic chuck 208. The mechanical gripper 201 is connected to one end of the mounting frame 207, and the electromagnetic chuck 208 is located at the bottom of the mechanical gripper 201. The mounting frame 207 is slidably connected to the third track 204. When the electromagnetic chuck 208 is powered on, it generates magnetic force and adheres to the magnetic block 801 of the product 800. Compared with traditional clamping gripping structures, electromagnetic adsorption gripping does not require aligning with the edge of the product 800, resulting in faster gripping speed and preventing damage to the product 800's outer shell. It is compatible with the preset magnetic adsorption material position of industrial power supplies, offering good gripping stability and preventing drops or collisions. By setting the magnetic block 801 on the product 800 itself, the electromagnetic chuck 208 can stably adsorb after being powered on, and smoothly release the material after the magnetic force disappears when the power is off, without the need for additional adjustment of the clamping distance. It adapts to the gripping needs of power supply products 800 of different specifications, making it more versatile.

[0049] like Figure 7 and Figure 8 As shown, the first mounting plate 203 is equipped with multiple photoelectric sensors 212, which are located at both ends of the third track 204. The mounting frame 207 is equipped with sensing plates 213 corresponding to the photoelectric sensors 212. When the mounting frame 207 moves to the end position of the third track 204, the sensing plate 213 triggers the photoelectric sensor 212, and the equipment can control the mounting frame 207 to stop moving and complete the next action, achieving precise positioning of the gripping position. At the same time, it prevents the mounting frame 207 from moving beyond its travel range and derailing, thus improving the safety of equipment operation. The photoelectric sensors 212 and sensing plates 213 monitor the movement trajectory of the mounting frame 207, avoiding deviation in the gripping position that could lead to material displacement, ensuring accurate positioning of the product 800 during conveying, and reducing the risk of conveying jams.

[0050] like Figure 4As shown, the gripping device also includes a movable plate 215, a fifth track 214 on the mechanical claw 201, and a second guide block 216 on the movable plate 215, the second guide block 216 being slidably connected to the fifth track 214; an electromagnetic chuck 208 is mounted on the movable plate 215, and a buffer assembly is provided on the electromagnetic chuck 208; the magnetic suction block 801 of the product 800 has a connection hole corresponding to the buffer assembly. The buffer assembly is inserted into the connection hole of the magnetic suction block 801, which can first position the relative position between the electromagnetic chuck 208 and the product 800 when the electromagnetic chuck 208 adsorbs and grips the product 800, preventing positional shifts during adsorption. It can also buffer the impact force generated when the electromagnetic chuck 208 adsorbs, preventing damage to the surface of the product 800 during magnetic attraction. The buffer assembly also limits the horizontal displacement of the product 800 on the electromagnetic chuck 208 during gripping and movement, preventing the product 800 from swaying or shifting due to inertia generated by equipment movement, thus improving the stability of gripping and conveying the product 800. The cooperation between the second guide block 216 and the fifth track 214 allows the movable plate 215 to make a certain degree of positional adjustment on the mechanical gripper, adapting to the processing errors of the magnetic block position on different products, improving the fault tolerance of gripping, and avoiding failure to complete adsorption gripping due to positional deviation.

[0051] like Figure 6 As shown, the buffer assembly includes a connecting frame 209, a connecting rod 210, and a support rod 211. The connecting frame 209 is C-shaped, with a through hole at its bottom. The connecting rod 210 passes through the through hole and can move up and down along it. The support rod 211 is connected to the top of the connecting frame 209. The connecting rod 210 and the support rod 211 are opposite to each other and spaced apart, thus forming a clearance space between the connecting rod 210 and the support rod 211 for the connecting rod 210 to move upward. The side wall of the connecting rod 210 has protrusions made of elastic material. When the electromagnetic chuck 208 approaches the magnetic block 801 of the product 800, the lower end of the connecting rod 210 first inserts into the connecting hole of the magnetic block 801 to position the relative position between the electromagnetic chuck 208 and the magnetic block 801. As the electromagnetic chuck 208 continues to move downwards, the connecting rod 210 is pressed towards the support rod 211 by the bottom wall of the connecting hole or the magnetic block 801. The gap between the connecting rod 210 and the support rod 211 gradually decreases, thus providing axial clearance travel for the connecting rod 210. At the same time, the protrusion on the side wall of the connecting rod 210 elastically abuts against the inner wall of the connecting hole to reduce the contact impact between the connecting rod 210 and the magnetic block 801 and to limit the lateral sway between the connecting rod 210 and the connecting hole, so that the electromagnetic chuck 208 can be smoothly aligned with the magnetic block 801 and complete the adsorption.

[0052] The mechanical gripper 201 is equipped with an infrared sensor 202, which is set downwards. The infrared sensor 202 can detect whether the electromagnetic chuck 208 has a product 800 attached to it. If the product 800 is not detected, the equipment will automatically issue an alarm and stop running to avoid empty conveying and waste cycle time, and ensure continuous and stable process.

[0053] like Figure 9 As shown, the conveying mechanism 300 further includes a second mounting plate 301, which is located below the first mounting plate 203. Two sets of first conveyor belts 302 are provided, each set positioned on either side of the second mounting plate 301. A first motor is mounted on the second mounting plate 301, and the first motor provides power to the two sets of first conveyor belts 302 via a first drive shaft. The two sets of first conveyor belts 302 operate synchronously, conveying the product 800 and smoothly transporting the NG power supply to the first lifting mechanism 400. The reserved space between the two conveyor belts ensures smooth transport of the product 800 while reducing the overall weight of the conveyor belts and minimizing power loss. The first motor synchronously drives the two sets of conveyor belts, preventing the product 800 from shifting due to the difference in speed between the two conveyor belts and ensuring accurate conveying positioning.

[0054] like Figure 10 and Figure 13 As shown, a third conveyor belt 403 is provided on the first conveyor platform 402, and a fourth conveyor belt 603 is provided on the second conveyor platform 602. Both the third conveyor belt 403 and the fourth conveyor belt 603 are capable of conveying products 800 in opposite directions. When the first conveyor platform 402 moves to a position corresponding to the first conveyor belt 302, the third conveyor belt 403 runs in the direction of receiving products 800 to receive the products 800 conveyed by the first conveyor belt 302; after the first conveyor platform 402 descends to a position corresponding to the NG inspection mechanism 500, the third conveyor belt 403 runs in the opposite direction to convey the products 800 to the NG inspection mechanism 500. When the second conveyor platform 602 moves to the position corresponding to the NG inspection mechanism 500, the fourth conveyor belt 603 runs in the direction of receiving the product 800 to receive the product 800 output by the NG inspection mechanism 500; after the second conveyor platform 602 descends to the position corresponding to the second conveyor belt 702, the fourth conveyor belt 603 runs in the opposite direction to transport the product 800 to the second conveyor belt 702. By adjusting the conveying directions of the third conveyor belt 403 and the fourth conveyor belt 603, the receiving and sending of the product 800 can be completed using the same conveyor belt, without the need for an additional pushing structure.

[0055] The first conveying platform 402 and the second conveying platform 602 respectively achieve lifting and lowering actions through the transmission of gears and racks. The first conveying platform 402 and the second conveying platform 602 are respectively meshed with drive gears on their sides. The drive gears are driven to rotate by the corresponding lifting motors. Through the gear and rack transmission, the conveying platform can be stably driven to move longitudinally along the track. Even when carrying heavy power supplies, there will be no slippage or slippage. The lifting and positioning are accurate and the operation is stable.

[0056] like Figure 12 As shown, the NG inspection mechanism 500 also includes a third mounting plate 501, a material carrier 502, a movable block, and a fifth conveyor belt 503. A second cylinder is provided on the third mounting plate 501, and the material carrier 502 is located on the piston rod 507 of the second cylinder. A guide rod 505 is provided at the bottom of the material carrier 502. A conduit 506 is provided on the third mounting plate 501, and the guide rod 505 passes through the conduit 506 to guide the lifting and lowering of the material carrier 502. The material carrier 502 is located below the barcode scanning camera 504. A crossbeam is provided on the inner wall of the cavity, and the movable block is slidably connected to the crossbeam. The barcode scanning camera 504 is located on the movable block. The movable block can be adjusted horizontally along the crossbeam, thereby moving the barcode scanning camera 504 to adapt to the scanning position of products 800 of different sizes. It can align with the product code and complete the barcode recognition without changing the placement angle of the product 800. It is compatible with the barcode scanning needs of various power supplies and has stronger versatility. The lifting and positioning structure of the material carrier block 502 can keep the product 800 stationary and stable during barcode scanning, effectively improving the barcode recognition success rate and avoiding barcode recognition failures caused by the shaking of the product 800, which requires repeated recognition and improves the operating efficiency of the equipment. Specifically, after the material carrier block 502 receives the product 800 fed in by the first lifting mechanism 400, the second cylinder drives the material carrier block to rise. The material carrier block 502 lifts the product 800, causing it to detach from the surface of the fifth conveyor belt 503. The product 800 is then stably positioned at the barcode scanning station, waiting for the barcode scanning camera 504 to complete the barcode recognition. After this, the second cylinder drives the material carrier block 502 to lower the product 800, placing it on the fifth conveyor belt 503. The fifth conveyor belt 503 then smoothly transports the product 800 to the second lifting mechanism 600, ensuring a stable and orderly barcode scanning process. The fifth conveyor belt 503 is used to transport the scanned product 800 to the second conveyor platform 602.

[0057] like Figure 11 and Figure 15As shown, the NG rework and automatic return equipment further includes a one-way guide device 900. The one-way guide device 900 includes a first cylinder 901, a connecting plate 902, a mounting base 903, an abutment rod 904, a rotating shaft 905, a roller 906, and a limiting rod 907. The mounting base 903 has a connecting groove, and the abutment rod 904 is rotatably connected to the connecting groove via the rotating shaft 905. A torsion spring is provided on the rotating shaft 905. The limiting rod 907 is located in the connecting groove and abuts against one end of the abutment rod 904. The abutment rod 904 can rotate in a direction that avoids the normal transport path of the product 800, and the limiting rod 907 is used to restrict the abutment rod 904 from rotating in a direction opposite to the avoidance direction. The roller 906 is located at the top of the abutment rod 904. The first cylinder 901 is mounted on the first mounting plate 203, the second mounting plate 301, the third mounting plate 501, the first conveying platform 402, or the second conveying platform 602 via the connecting plate 902. The output end of the first cylinder 901 is connected to the mounting base 903 to drive the mounting base 903 to rise and fall. When the product 800 moves in the normal conveying direction, the side of the product 800 presses against the roller 906, causing the abutment rod 904 to rotate in a direction that avoids the product 800, overcoming the elastic force of the torsion spring, so that the product 800 can pass through. When the product 800 moves in the opposite direction, the limiting rod 907 restricts the abutment rod 904 from rotating in the opposite direction, causing the roller 906 to abut against the product 800, thereby restricting the product 800 from continuing to move in the opposite direction. When it is necessary to release the limiting effect of the roller 906 on the product 800, the first cylinder 901 drives the mounting base 903 to move downward, causing the roller 906 to descend below the conveying plane where the product 800 is located.

[0058] Specifically, the first mounting plate 203 is provided with multiple one-way guide devices 900 facing the first lifting mechanism 400, and the first conveying platform 402, the second conveying platform 602, and the third mounting plate 501 are each provided with two one-way guide devices 900 with opposite guiding directions. When the first conveying platform 402 and the second conveying platform 602 are in lifting motion, the corresponding one-way guide device 900 can stably restrict the product 800 on the first conveying platform 402 or the second conveying platform 602; when scanning the product 800, the one-way guide device 900 on the third mounting plate 501 can stably restrict the product 800 on the loading block 502. When it is necessary to transport the product 800, the first cylinder 901 drives the mounting base 903 to move downward, so that the roller 906 drops below the conveying plane where the product 800 is located, thereby releasing the restriction on the product 800 and allowing the product 800 to be smoothly transported to the next station.

[0059] This application, through the setting of conveying mechanism 300, first lifting mechanism 400, and second lifting mechanism 600, transforms the conveying of product 800 into longitudinal transportation, making full use of the longitudinal space of the frame 100 cavity, eliminating the need to occupy a large horizontal area, significantly reducing the overall footprint of the equipment, and allowing for more efficient use of workshop space; at the same time, the entire process automatically completes loading, conveying, barcode scanning for warehousing, and return to the board for output, eliminating the need for manual transfer of NG product 800, which reduces the intensity of manual labor, avoids the problem of picking the wrong product 800 or missing information during manual transfer, and improves the accuracy and automation of the NG return to the board for repair process.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
