[0002] In automated production line operations, product conveying, stacking, and unloading are core processes. Currently, most conventional product stacking equipment on the market uses single-side drive, chain transmission, or simple lifting structures, resulting in poor stacking accuracy; at the same time, it cannot be adapted to cleanroom operating environments.

[0003] Chinese patent (publication number: CN207361362 U) discloses a structure for automatic storage and timely loading / unloading of OLED stacked PCB boards. A conveyor mechanism is connected to one side of the main support frame. A cover plate is located on the top of the main support frame, and a three-color light is located on one side of the top of the cover plate. An upper support plate is located in the middle of the inner cavity of the main support frame, and a stacking body is located at the bottom of the inner cavity. A lead screw is located in the middle of one side of the stacking body, and guide posts are located on both sides of the lead screw. A lower synchronous pulley is located at the bottom of the stacking body and connected to a lower synchronous belt. An upper synchronous pulley is located on the upper support plate and connected to an upper synchronous belt, with the lead screw positioned between the lower synchronous belt and the upper synchronous pulley. A servo motor is connected to one side of the upper synchronous pulley. However, this structure for automatic storage and timely loading / unloading of OLED stacked PCB boards is not suitable for cleanroom operations. Summary of the Invention

[0004] This invention is made to solve the above-mentioned problems, and aims to provide a synchronous lifting stacking mechanism and its usage method that can be adapted to a cleanroom environment for product stacking. To achieve the above objective, the technical solution adopted by this invention is as follows: a synchronous lifting stacking mechanism, including a housing, a mounting bracket provided inside the housing, a synchronous lifting component provided on the mounting bracket, a stacking carrier component provided on the synchronous lifting component, and a production line structure provided below the synchronous lifting component.

[0005] The synchronous lifting assembly includes a first support shaft, an idler pulley, a belt, and a dual-axis motor. The first support shaft is located at one end of the mounting bracket, and the idler pulley is located at the other end of the mounting bracket. A drive pulley is mounted on the first support shaft. One end of the belt is fitted onto the drive pulley, and the other end of the belt is fitted onto the idler pulley. The belt is connected to the stacking carrier assembly. The dual-axis motor is connected to the housing, and the output shaft of the dual-axis motor is connected to a steering gear. One end of the first support shaft is connected to the steering gear.

[0006] The stack carrier assembly includes a lifting plate, which is spaced apart on a belt. Lifting blocks are spaced apart on the lifting plate. The product is placed on the lifting blocks. A limiting groove plate is provided at the end of the mounting bracket. Lifting wheels are provided at both ends of the lifting plate and are located in the limiting groove plate.

[0007] The mounting bracket includes a support frame, a first mounting plate is provided at the bottom of the support frame, an idler wheel is provided on the first mounting plate, a second mounting plate is provided at the top of the support frame, and an intermediate support nylon wheel is provided on the second mounting plate, the intermediate support nylon wheel abutting against the first support shaft.

[0008] The support frame includes a square plate, a reinforcing plate inside the square plate, protruding plates at the corners of the square plate, and a horizontal plate inside the box, with the protruding plates connected to the horizontal plates.

[0009] The assembly line structure includes a support frame located at the bottom of the housing. A second support shaft is mounted on the support frame, with rollers at both ends of the second support shaft. A synchronous belt is connected to the second support shaft, and an assembly line motor is mounted on the support frame and connected to the synchronous belt.

[0010] A blocking cylinder and a photoelectric sensor are provided at the bottom of the support frame. The telescopic rod of the blocking cylinder abuts against the product. Assembly plates are provided on both sides of the support frame. Sliding wheels are provided on the assembly plates and abut against the sides of the product.

[0011] The support frame includes a support plate, which is spaced apart at the bottom of the box. A first fixing plate is connected to the end and middle of the support plate. A pad is provided between the support plate and the box. A second fixing plate is provided on the first fixing plate. The assembly line motor is provided on the second fixing plate.

[0012] The housing has a flow line through hole, which is on the same horizontal plane as the second support shaft. The housing also has a maintenance door with transparent glass.

[0013] A method for using a synchronous lifting stack mechanism, characterized in that: specifically: Product conveying and positioning: The assembly line structure is started, and the assembly line motor drives the second support shaft and rollers to rotate, which in turn drives the rollers to convey the product into the box; the photoelectric sensor detects that the product has arrived, triggering the extension of the blocking cylinder to limit the product to the docking position of the stack carrier assembly, and the assembly line motor stops rotating; Synchronous lifting preparation: The dual-axis motor starts, and the power is distributed to the first support shaft through the steering gear. The drive pulley and idler pulley mesh with the belt, so that the belt forms a vertical closed-loop transmission along the mounting bracket. The lifting block located at the bottom of the product is lifted by the belt. The lifting block lifts the product up one station, reserving stacking space for the next product. This process is repeated to achieve vertical stacking of multiple products. Material discharge reset: When material discharge is required, the dual-axis motor reverses, and the belt drives the lifting plate and the product to move downward, conveying the product layer by layer to the assembly line structure. After one product is discharged, the dual-axis motor reverses again until the discharge is complete.

[0014] The technical advantages of this invention are as follows: Products enter through the through-hole of the assembly line. The assembly line motor drives the synchronous belt and rollers to rotate. The sliding wheel laterally supports the product. After the photoelectric sensor detects the product's position, the blocking cylinder extends to position the product. The dual-axis motor starts, driving the first support shafts on both sides and the drive wheel to rotate synchronously via the steering gear. The closed-loop belt operation drives the lifting plate to rise, and the lifting block lifts the product to one workstation. This process of feeding and lifting is repeated to achieve multi-layer vertical stacking. During discharge, the dual-axis motor reverses, and the lifting block drives the product to descend layer by layer. After the product falls onto the rollers, it is fed out by the assembly line. Discharge is completed, and the carrier is reset. This achieves automated product conveying, stacking, and discharge. Through the coordinated operation of various components, the entire process from product entry into the box, vertical stacking to discharge and reset is completed. It has the advantages of stable operation, accurate positioning, low dust and environmental protection, high efficiency and convenience, and is suitable for the product stacking requirements of various automated production lines.

[0017] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0018] like Figures 1-6As shown, a synchronous lifting stacking mechanism includes a housing 1, a mounting bracket 2 inside the housing 1, a synchronous lifting component 3 mounted on the mounting bracket 2, a stacking carrier component 4 mounted on the synchronous lifting component 3, and a conveyor structure 5 below the synchronous lifting component 3. The housing 1 serves as the outer shell of the entire synchronous lifting stacking mechanism. The mounting bracket 2, synchronous lifting component 3, stacking carrier component 4, and conveyor structure 5 are housed inside the housing 1. The housing 1 accommodates, supports, and protects all internal components, forming a relatively enclosed working space to ensure internal structural stability and safety, while also meeting the requirements for cleanroom environments and preventing external dust from entering. The mounting bracket 2 is entirely housed inside the housing 1 and fixedly connected to it. The synchronous lifting component 3 is mounted on the mounting bracket 2, and the stacking carrier component 4 is mounted on the synchronous lifting component 3. The synchronous lifting component 3 provides synchronous, stable, and low-dust lifting power, driving the stacking carrier component 4 to perform vertical lifting and lowering movements, achieving layered stacking and lifting of products 8, meeting the requirements for heavy-duty, cleanroom, and high-cycle operation. The stack carrier assembly 4 is mounted on the synchronous lifting assembly 3 and driven by the synchronous lifting assembly 3. The stack carrier assembly 4 receives the products 8 conveyed from the assembly line structure 5. Driven by the synchronous lifting assembly 3, it achieves vertical stacking, buffering, and positioning of multiple layers of products 8, ensuring that the products 8 do not tilt, shift, or fall during the lifting process. The assembly line structure 5 is located inside the housing 1, within the closed loop formed by the synchronous lifting assembly 3. The assembly line structure 5 conveys the products 8 into the housing 1, and the synchronous lifting assembly 3 drives the stack carrier assembly 4 to receive and lift the products 8 upwards by one stacking station. Then, the feeding and lifting of product 8 are repeated to achieve vertical stacking and buffering of multi-layer product 8 within the housing 1.

[0019] The synchronous lifting assembly 3 includes a first support shaft 301, an idler pulley 302, a belt 303, and a dual-axis motor 304. The first support shaft 301 is located at one end of the mounting bracket 2, and the idler pulley 302 is located at the other end of the mounting bracket 2. A drive pulley 305 is mounted on the first support shaft 301. One end of the belt 303 is fitted onto the drive pulley 305, and the other end of the belt 303 is fitted onto the idler pulley 302. The belt 303 is connected to the stacking carrier assembly 4. The dual-axis motor 304 is connected to the housing 1. The output shaft of the dual-axis motor 304 is connected to a steering gear 306, and one end of the first support shaft 301 is connected to the steering gear 306. Mounting brackets 2 are symmetrically arranged inside the housing. A first support shaft 301 is positioned at the top of the mounting brackets 2. Idler pulleys 302 are spaced apart at the bottom of the mounting brackets 2. Drive pulleys 305 are spaced apart on the first support shaft 301, with each drive pulley 305 corresponding to one of the idler pulleys 302. One end of a belt 303 is fitted onto the drive pulley 305, and the other end is fitted onto the idler pulley 302, forming a vertical closed loop. The idler pulleys 302 support, tension, and reverse the belt 303, working in conjunction with the drive pulleys 305 to form a vertical closed-loop transmission, ensuring that the belt 303 does not slip, loosen, or move smoothly during operation. The belt 303 is fixedly connected to the stacking carrier assembly 4, driving the stacking carrier assembly 4 to rise and fall together. A dual-axis motor 304 is fixedly connected to the housing 1, and the output shaft of the dual-axis motor 304 is connected to a steering gear 306. The dual-axis motor 304 provides power to the entire lifting mechanism. Its dual-output shaft structure allows for simultaneous power output to both sides. The input end of the steering gear 306 is connected to the output shaft of the dual-axis motor 304, and the output end of the steering gear 306 is connected to one end of the first support shaft 301. This facilitates synchronized dual-side drive by cooperating with the steering gear 306. The steering gear 306 reverses and distributes the power from the dual-axis motor 304, ensuring that the symmetrical first support shafts 301 rotate at the same speed, in the same direction, and synchronously, guaranteeing consistent lifting and lowering of the belts 303 on both sides.

[0020] Power is output from the dual-axis motor 304 to the steering gear 306; the steering gear 306 distributes the power and transmits it to the first support shafts 301 on both sides, causing the first support shafts 301 to rotate synchronously; the first support shafts 301 drive the drive wheel 305 to rotate; the drive wheel 305 drives the belt 303 sleeved on its outside to move; the other end of the belt 303 is sleeved on the idler wheel 302 symmetrically arranged at the other end of the mounting bracket 2, forming a vertical closed-loop transmission; during the movement of the belt 303, the belt 303 drives the stacking carrier assembly 4 connected to it to achieve synchronous lifting and lowering, and the stacking carrier assembly 4 drives the product 8 to complete the lifting, stacking and lowering of the product 8 for discharge.

[0021] The stacking carrier assembly 4 includes lifting plates 401, which are spaced apart on the belt 303. Lifting blocks 402 are spaced apart on the lifting plates 401. The product 8 is placed on the lifting blocks 402. A limiting groove plate 403 is provided at the end of the mounting bracket 2. Lifting wheels 404 are provided at both ends of the lifting plates 401, and the lifting wheels 404 are located within the limiting groove plate 403. The lifting plates 401 are rectangular bearing plates, with their surfaces arranged horizontally. The lifting plates 401 are fixedly mounted on the belt 303 of the synchronous lifting assembly 3 at intervals and are fixedly connected to the belt body of the belt 303 by bolts, moving vertically in a circular motion with the belt 303. The lifting blocks 402 are block-shaped structures with a certain bearing height, fixedly installed at the ends of the lifting plates 401 in a spaced-apart manner. When the belt 303 drives the product 8 to move, the product 8 rests on the upper surface of the lifting blocks 402, achieving stable contact with the carrier assembly. The lifting blocks 402 on both sides of product 8 jointly support product 8. Driven by the lifting plate 401, the lifting blocks 402 lift product 8 upwards, completing one layer of stacking. The lifting wheels 404 are cylindrical rollers, rotatably mounted on both ends of the lifting plate 401 via axles. The outer circumferential surface of the lifting wheels 404 rolls in contact with the inner wall of the limiting groove plate 403 on the mounting bracket 2. During the lifting and lowering process of the lifting plate 401, the lifting wheels 404 continuously roll within the groove of the limiting groove plate 403. The limiting groove plate 403 constrains the movement trajectory of the lifting wheels 404, thereby forcing the lifting plate 401 to rise and fall smoothly in the vertical direction, ensuring the stability and accuracy of product 8 lifting.

[0022] The mounting bracket 2 includes a support frame 21, a first mounting plate 201 is provided at the bottom of the support frame 21, an idler wheel 302 is provided on the first mounting plate 201, a second mounting plate 202 is provided at the top of the support frame 21, and an intermediate support nylon wheel 203 is provided on the second mounting plate 202, the intermediate support nylon wheel 203 abuts against the first support shaft 301. The support frame 21 is the main frame of the mounting bracket 2. It is vertically arranged and fixedly installed inside the box 1, and rigidly connected to the inner wall of the box 1. The bottom of the support frame 21 supports the first mounting plate 201, the top supports the second mounting plate 202, and the two sides are fixed with limiting groove plates 403. The first mounting plate 201 is horizontally fixed at the bottom of the support frame 21 and is bolted to the support frame 21. The plate surface is kept horizontal. The idler wheel 302 is rotatably installed on the first mounting plate 201. The second mounting plate 202 is horizontally fixed at the top of the support frame 21 and is rigidly connected to the support frame 21. The plate surface is parallel to the bottom first mounting plate 201. The middle support nylon wheel 203 is installed on the second mounting plate 202. The middle support nylon wheel 203 has two nylon wheels, and the circumferential surface of the wheel body abuts against the outer peripheral wall of the first support shaft 301. It provides flexible support for the first support shaft 301, reducing vibration and noise when the first support shaft 301 rotates; at the same time, it helps to correct the rotation trajectory of the first support shaft 301, avoids shaft wobble that causes belt 303 to run off-center and abnormal meshing of drive pulley 305, and extends the service life of the first support shaft 301.

[0023] The support frame 21 includes a square plate 211, with a reinforcing plate 212 inside the square plate 211. A protruding plate 213 is located at the corner of the square plate 211. A horizontal plate is installed inside the housing 1, and the protruding plate 213 is connected to the horizontal plate. The square plate 211 is the main body of the support frame 21, forming a vertically arranged frame structure. The square plate 211 is located inside the housing 1. The reinforcing plate 212 is installed within the cavity of the square plate 211 to improve the bending and torsional resistance of the support frame 21, preventing bending, deformation, and swaying of the support frame 21 during heavy lifting and long-term operation. The protruding plate 213 is fixedly installed at each corner of the square plate 211, extending horizontally towards one side of the inner wall of the housing 1. A horizontal plate is fixed at a corresponding height on the inner wall of the housing 1. The surface of the protruding plate 213 fits against the surface of the horizontal plate, and a detachable fastening connection is achieved by bolts. The bottom end face of the square plate 211 is fixedly connected to the first mounting plate 201, the top end face is fixedly connected to the second mounting plate 202, and the side end is fixedly connected to the limiting groove plate 403, forming a complete support frame.

[0024] The assembly line structure 5 includes a support frame 51, which is located at the bottom of the housing 1. A second support shaft 501 is mounted on the support frame 51, with rollers 502 at both ends of the second support shaft 501. A synchronous belt 503 is connected to the second support shaft 501, and an assembly line motor 504 is mounted on the support frame 51, connected to the synchronous belt 503. The support frame 51 is fixedly installed inside the bottom of the housing 1, directly below the support frame 21, and rigidly connected to the bottom inner wall of the housing 1, serving as the overall load-bearing frame of the assembly line structure 5. Its horizontal layout ensures a flat conveying plane. The second support shaft 501 and the assembly line motor 504 are mounted on the support frame 51, and the position of the support frame 51 corresponds vertically to the lifting block 402 of the stacking carrier assembly 4, ensuring precise docking of the products 8. The second support shaft 501 is horizontally mounted on the support frame 51 and is rotatably connected to the side wall of the support frame 51 via bearings. Multiple second support shafts 501 are arranged at equal intervals along the length of the support frame 51. The gap between adjacent second support shafts 501 allows the lifting block 402 to pass through and lift the product 8 without interference.

[0025] To ensure a flat conveying surface, a synchronous belt 503 is fitted onto the second support shaft 501, with the other end of the synchronous belt 503 fitted onto the assembly line motor 504. When material needs to be fed, the assembly line motor 504 is powered on and starts, outputting power to drive the synchronous belt 503 to rotate. The synchronous belt 503 drives the second support shaft 501 to rotate. Rollers 502 are coaxially fixed at both ends of the second support shaft 501, and the shaft and rollers 502 rotate synchronously. When conveying product 8, the rollers 502 are located at the bottom of product 8. As the rollers 502 rotate, product 8 moves, thus realizing the conveying of product 8.

[0026] A blocking cylinder 6 and a photoelectric sensor are installed at the bottom of the support frame 51. The telescopic rod of the blocking cylinder 6 abuts against the product 8. Assembly plates 7 are installed on both sides of the support frame 51, and sliding wheels 701 are installed on the assembly plates 7, which abut against the sides of the product 8. The photoelectric sensor is installed at the bottom of the support frame 51, with the detection end of the photoelectric sensor facing upwards and directly facing the conveying path of the synchronous belt 503. The electronic control end of the photoelectric sensor is connected to an external control module and is linked with the blocking cylinder 6 and the assembly line motor 504 to realize signal transmission and action triggering. The assembly plates 7 are symmetrically arranged on the left and right sides of the support frame 51, vertically arranged along the conveying direction of the assembly line. The assembly plates 7 are rigidly connected to the side wall of the support frame 51, and the plate surface is perpendicular to the conveying plane of the synchronous belt 503. The assembly plates 7 are arranged along the conveying direction and provide a dedicated mounting carrier for the sliding wheels 701, ensuring that the sliding wheels 701 on both sides are symmetrically aligned. The pulley 701 provides lateral guidance for the product 8 during transport, preventing it from swaying, shifting, or even falling off the synchronous belt 503. This ensures the product 8 is smoothly transported along the centerline of the assembly line and accurately reaches its designated position. The blocking cylinder 6 is fixedly installed at the bottom of the support frame 51, located at the central axis of the support frame 51. The telescopic rod is vertically upward, facing the end of the product 8 transported to its designated position on the assembly line. The blocking cylinder 6 is bolted to the support frame 51 and connected to the support frame 51 via an electrical control circuit, forming a linkage positioning structure. As roller 502 rotates, product 8 is conveyed forward. When the photoelectric sensor detects that product 8 has entered, it immediately transmits an electrical signal to trigger the blocking cylinder 6 to act. The telescopic rod extends upward and presses against the bottom end face of product 8. When product 8 reaches the position, it forces product 8 to stop moving. Then, the stacking carrier assembly 4 lifts product 8 up. The next product 8 moves forward as roller 502 rotates. When it reaches the position, it will be blocked by the telescopic rod, forcing product 8 to stop moving. Then, the stacking carrier assembly 4 lifts product 8 up, and the cycle repeats.

[0027] The support frame 51 includes support plates 511, which are spaced apart at the bottom of the housing 1. First fixing plates 512 are connected to the ends and middle of the support plates 511. Pads 513 are placed between the support plates 511 and the housing 1. A second fixing plate 514 is mounted on the first fixing plate 512, and the assembly line motor 504 is mounted on the second fixing plate 514. The support plates 511 are spaced apart and parallel to each other at the bottom of the housing 1, arranged along the conveyor direction. The bottom of the support plates 511 is connected to the inner wall of the housing 1 via pads 513. The ends and middle of the support plates 511 are laterally reinforced and connected via the first fixing plates 512, forming a stable frame foundation. Pads 513 are placed between the support plates 511 and the inner wall of the housing 1, cushioning the bottom of the support plates 511, and are securely connected to the support plates 511 and the inner wall of the housing 1 by bolts. The assembly line motor 504 is mounted on the second fixing plate 514, providing a sturdy and flat mounting surface for the assembly line motor 504.

[0028] The housing 1 has a conveyor through-hole 101, which is on the same horizontal plane as the second support shaft 501. A maintenance door 102 is also provided on the housing 1, with a transparent glass 103 installed on it. The conveyor through-hole 101 is directly located on the side wall of the housing 1, forming a through-hole structure. The opening is precisely aligned with the second support shaft 501 inside the housing 1, and both are on the same horizontal plane. The through-hole size is adapted to the shape and specifications of the product 8 to be conveyed, ensuring smooth passage. The edges of the through-hole are blunted to prevent scratching the product 8 or operators. The maintenance door 102 is located on the side wall of the housing 1, and its hinge is movably connected to the side wall of the housing 1, allowing for flexible opening and closing. The transparent glass 103 is embedded and fixed within the pre-reserved opening of the maintenance door 102. It is made of tempered transparent glass with sealed and reinforced edges, ensuring a tight and seamless fit with the maintenance door 102.

[0029] A method for using a synchronously promoted stack mechanism is as follows: Product conveying and positioning: Start the assembly line structure 5, the assembly line motor 504 drives the second support shaft 501 and roller 502 to rotate, and drive the roller 502 to convey the product 8 into the box 1; the photoelectric sensor detects that the product 8 has arrived, triggers the blocking cylinder 6 to extend, and limits the product 8 to the docking position of the stack carrier assembly 4, and the assembly line motor 504 stops rotating. When the assembly line motor 504 is powered on, it drives the synchronous belt 503, the second support shaft 501, and the rollers 502 to rotate. Multiple sets of equidistantly arranged second support shafts 501 and rollers 502 work together. External products 8 enter the interior of the housing 1 horizontally through the assembly line through-hole 101 on the side wall of the housing 1 and fall smoothly onto the upper surface of the rollers 502. The sliding wheels 701 on the mounting plates 7 on both sides of the support frame 51 roll and abut against the sides of the products 8, providing lateral guidance and straightening to prevent the products 8 from shifting left or right during the conveying process and to ensure that the products 8 move smoothly along the center line of the assembly line.

[0030] Product 8 is continuously conveyed by roller 502 until it moves to the preset positioning area. At this time, the photoelectric sensor at the bottom of support frame 51 detects that product 8 is blocking it and immediately triggers a sensing signal, which is synchronously transmitted to the electronic control module of assembly line motor 504 and blocking cylinder 6. After receiving the signal, the electronic control module immediately controls the assembly line motor 504 to shut down and the synchronous belt 503 to stop running, and product 8 no longer moves with the belt. At the same time, the blocking cylinder 6 is triggered to act, and its telescopic rod extends vertically upward and abuts against the bottom end face of product 8, limiting product 8 to the docking position directly above lifting block 402 to prevent product 8 from moving out of position. Synchronous lifting preparation: The dual-axis motor 304 starts, and the power is distributed to the first support shaft 301 through the steering gear 306. The drive wheel 305 and idler wheel 302 engage with the belt 303, so that the belt 303 forms a vertical closed-loop transmission along the mounting bracket 2. The lifting block 402 located at the bottom of the product 8 is lifted by the belt 303. The lifting block 402 lifts the product 8 up one station, reserving stacking space for the next product 8. This process is repeated to achieve vertical stacking of multiple layers of products 8. When the dual-axis motor 304 is powered on, the two output shafts rotate synchronously, transmitting power to the steering gear 306. The steering gear 306 reverses, splits, and distributes the power, evenly transmitting it to the symmetrically arranged first support shafts 301. This ensures that the first support shafts 301 on both sides rotate at the same speed, in the same direction, and synchronously, preventing lifting deviation caused by power lag on one side. The rotation of the first support shafts 301 drives the drive wheel 305 to rotate synchronously. The drive wheel 305 meshes with the belt 303, driving the belt 303 to perform a vertical closed-loop motion along the mounting bracket 2. The other end of the belt 303 is fitted with an idler wheel 302 on the first mounting plate 201. The idler wheel 302 rotates passively with the belt 303, realizing the reversal and tension of the belt 303. The intermediate support nylon wheel 203 on the second mounting plate 202 rolls against the first support shaft 301, assisting in supporting the shaft, reducing radial runout, and further optimizing the tension and transmission stability of the belt 303.

[0031] During the closed-loop operation of belt 303, it drives the lifting plate 401 fixedly connected to it to move synchronously; the lifting wheels 404 at both ends of the lifting plate 401 roll vertically along the limiting groove plate 403 at the end of the mounting bracket 2, constraining the movement trajectory of the lifting plate 401, preventing horizontal swaying and tilting during the lifting process, and ensuring that the lifting plate 401 always remains in a horizontal state; the lifting block 402 on the lifting plate 401 passes through the gap between the adjacent second support shaft 501, lifts the positioned product 8, and smoothly raises it to a standard station, reserving sufficient stacking space for the next product 8; After a single lift is completed, the next product 8 will enter along with the previous product. The belt 303 continues to lift product 8. Each time a product 8 is fed, a station lift is completed, gradually realizing the vertical stacking of multiple layers of products 8. The rotation speed of the belt 303 is matched with the rotation speed of the second support shaft 501 to ensure that after product 8 is lifted, when the next product arrives at the position, the belt 303 can drive the lifting plate 401 and the lifting block 402 to the position to lift product 8.

[0032] Material discharge reset: When material discharge is required, the dual-axis motor 304 reverses, and the belt 303 drives the lifting plate 401 and product 8 to move downward, conveying product 8 layer by layer to the assembly line structure 5. After one product 8 is discharged, the reverse action of the dual-axis motor 304 is repeated until the discharge is completed. The dual-axis motor 304 is powered in reverse and the power is transmitted to the first support shaft 301 through the steering gear 306, which drives the drive wheel 305 to rotate in the opposite direction, thereby driving the belt 303 to make a reverse vertical closed-loop movement along the mounting bracket 2, which drives the lifting plate 401 and the lifting block 402 to move downward smoothly.

[0033] The belt 303 drives the stack carrier assembly 4 to descend layer by layer until the bottom product 8 is smoothly placed on the upper surface of the roller 502. The assembly line motor 504 starts and drives the synchronous belt 503 to rotate in the opposite direction, so that the product 8 is smoothly sent out of the box 1 through the assembly line through hole 101, completing the discharge of a single product 8.

[0034] After a single product 8 is finished being discharged, the dual-axis motor 304 continuously reverses and repeats the reverse lifting action, driving the remaining stacked products 8 to continue to descend one station, placing the next product 8 onto the roller 502. The roller 502 rotates and starts feeding again, and this action is repeated until all stacked products 8 are discharged.

[0035] Product 8 enters through the conveyor belt through-hole 101 in the housing. The conveyor belt motor 504 drives the synchronous belt 503 and roller 502 to rotate. The sliding wheel 701 laterally supports product 8. After the photoelectric sensor detects the position, the blocking cylinder 6 extends to position product 8. The dual-axis motor 304 starts, driving the first support shafts 301 on both sides and the drive wheel 305 to rotate synchronously via the steering gear 306. The belt 303 operates in a closed loop, driving the lifting plate 401 to rise. The lifting block 402 lifts product 8 to one station. Then, the feeding and lifting are repeated to achieve multi-layer vertical stacking. During discharge, the dual-axis motor 304 reverses, and the lifting block 402 drives product 8 to descend layer by layer. After product 8 falls onto the roller 502, it is fed out of the conveyor belt. After discharge, the carrier is reset. This realizes the automated conveying, stacking and discharge of product 8. Through the linkage and cooperation of various components, the entire process from product 8 entering the housing, vertical stacking to discharge and reset is completed. It has the advantages of stable operation, accurate positioning, low dust and environmental protection, high efficiency and convenience, and is suitable for the product 8 stacking requirements of various automated production lines.
