Description

Technical Field

[0001] This invention relates to the field of component processing technology, specifically to a multi-process integrated processing system for display bracket components. Background Technology

[0002] Monitor stands are used to support monitors and provide angle and height adjustments. The base plate at the bottom of the monitor stand serves as the core support, typically with a large support area and several connection holes. Screws pass through these holes to connect it to other components of the stand. To improve aesthetics and extend its lifespan, the base plate is usually painted. Therefore, the processing of the base plate requires sequential completion of key steps such as feeding, punching, painting, and drying, placing high demands on processing precision, surface quality, and production efficiency. Currently, the mainstream processing mode in the industry is still based on a decentralized process layout, which has many technical drawbacks: each process is independent, and the workpieces need to be manually transferred and loaded / unloaded between feeding, punching, painting, and drying. This not only leads to low production efficiency and high labor costs but also easily causes scratches and bumps to the workpiece surface during transfer. Especially when the paint is not dry after painting, manual contact or transfer can directly cause paint damage and contamination, seriously affecting the product's appearance qualification rate. Therefore, developing an integrated, highly automated multi-process processing system is key to solving the pain points of the existing technology. Summary of the Invention

[0003] Based on the above-mentioned problems existing in the prior art, the purpose of this invention is to provide a multi-process integrated processing system for display bracket components, which has a high degree of automation and takes less time.

[0004] The technical solution adopted by this invention to solve its technical problem is: a multi-process integrated processing system for display bracket components, including a feeding mechanism, a punching mechanism, a painting mechanism, a drying mechanism, and a transfer mechanism. The feeding mechanism includes a loading platform, a hopper for storing workpieces, and a pushing component. A punching area is provided on the base of the punching mechanism. The pushing component is used to push the workpieces in the hopper to the punching area. The drying mechanism includes a drying chamber. A partition is provided in the drying chamber to divide the drying chamber into a drying room and a painting room. The painting mechanism is located in the painting room. A clamping component for holding workpieces is provided in the painting room. The clamping component can move repeatedly between the painting room and the drying room to complete the painting and drying processes. The transfer mechanism is used to transfer the workpieces that have completed punching processing from the punching area to the clamping component.

[0005] Furthermore, the hopper is located on the top surface of the loading platform, and several workpieces are stacked inside the hopper. A through groove is opened at the bottom of the hopper, and the depth of the through groove is between 1.2 and 1.8 times the height of the workpiece. The pushing assembly includes a first cylinder located on one side of the through groove in the X-axis direction. The movable end of the first cylinder is provided with a push plate for pushing the workpiece to the punching area.

[0006] Furthermore, first limiting strips are symmetrically arranged on both sides of the punching area along the Y-axis. The two first limiting strips extend along the X-axis and fit against the discharge end of the hopper. The distance between the two first limiting strips matches the length of the workpiece to guide and limit the movement direction of the workpiece. A second limiting strip is arranged on the side of the punching area away from the first cylinder to limit the movement stroke of the workpiece. A pressure sensor is arranged between the first cylinder and the push plate.

[0007] Furthermore, the punching area is provided with through holes corresponding to the position and size of the punch, for the punch to pass through to complete the punching operation and discharge waste. At least two rotary clamping cylinders are arranged around the outside of the punching area. The ends of the rotary clamping cylinders are fixedly connected to downward-facing pressure blocks via connecting rods. The bottom surface of the pressure blocks is provided with rubber pads.

[0008] Furthermore, the transfer mechanism includes a guide rail arranged along the Y-axis and a lifting platform slidably connected to the guide rail. The lifting platform can move stably along the guide rail. A turntable is rotatably arranged on the top surface of the lifting platform. A first motor for driving the turntable to rotate is arranged inside the lifting platform. A fixed plate facing the punching mechanism is fixedly arranged on the turntable. A connecting plate is hinged to the end of the fixed plate away from the turntable. The connecting plate is initially parallel to the fixed plate, and at least two pneumatic suction cups are evenly arranged on the bottom surface of the connecting plate. The paint spraying chamber is located on one side of the transfer mechanism along the Y-axis. The transfer mechanism transfers the workpiece from the punching area to the clamping assembly of the paint spraying chamber through lifting, translation, and rotation actions.

[0009] Furthermore, the partition plate has a slot extending through its thickness direction, and a synchronous belt extending through the slot is provided in the drying chamber. Synchronous pulleys are rotatably installed at the four corners of the synchronous belt, one of which is connected to the drive motor. Several mounting blocks are spaced along the length of the synchronous belt, and a through groove extending through the Y-axis is provided on the mounting block. A rotating shaft is rotatably installed in the through groove via a bearing. The clamping assembly is fixedly installed at the end of the rotating shaft facing the transfer mechanism. The clamping assembly includes a mounting plate fixedly connected to the rotating shaft and fixing rods evenly arranged on the mounting plate. The position and number of the fixing rods correspond to the preset holes on the workpiece. The workpiece is positioned and clamped by fitting it onto the fixing rods through the holes.

[0010] Furthermore, a gear is fixedly sleeved at the end of the rotating shaft away from the fixed rod, and an annular rack is fixedly installed on the inner wall of the drying chamber corresponding to the moving path of the synchronous belt. The shape of the rack is adapted to the trajectory of the synchronous belt, and the gear and rack always maintain meshing transmission. The rotating shaft includes a short shaft and a long shaft, and the short shaft and the long shaft are alternately distributed.

[0011] Furthermore, the drying chamber is equipped with a first limiting plate and a second limiting plate in a ring shape corresponding to the moving path of the synchronous belt. The first limiting plate is located outside the second limiting plate. Both limiting plates are connected to the inner wall of the drying chamber through a mounting bracket. A ring-shaped passage for the rotating shaft to move is formed between the first limiting plate and the second limiting plate. The width of the ring-shaped passage matches the diameter of the rotating shaft. The inner walls of the first limiting plate and the second limiting plate are provided with a wear-resistant lubricating layer.

[0012] Furthermore, several air pipes are pre-embedded inside the partition, and the air inlet ends of the air pipes are all connected to a drying air source device. The air outlet ends of the air pipes are evenly distributed on the outside of the slot and face the inside of the spraying chamber. The spraying mechanism includes several movable and adjustable spray heads. The spray heads are connected to a paint supply device through pipes for uniformly spraying paint onto the surface of the workpiece. An air suction hood is fixedly installed on the side of the spraying chamber away from the partition. The opening of the air suction hood faces the spraying area, and the air suction hood is connected to a negative pressure machine through pipes.

[0013] Furthermore, the drying chamber is continuously supplied with clean air that has undergone drying and impurity removal treatment through a circulation pipe. The circulation pipe is equipped with a filter element, and the drying chamber is also uniformly equipped with several electric heating tubes.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. No manual intervention is required for workpiece transfer, loading and unloading, and process switching. The feeding mechanism automatically pushes materials through the storage bin and pusher plate. The transfer mechanism completes the workpiece transfer through multiple actions such as lifting, translation, and rotation. The synchronous belt drive drives the clamping components to circulate between the painting chamber and the drying chamber, realizing the fully automated connection of the "feeding, punching, painting, and drying" process. The production efficiency is increased by more than 50% compared with decentralized processing, and the labor cost and process waiting time are significantly reduced.

[0015] 2. Through the meshing of gears and ring racks, the workpiece rotates continuously while moving along the synchronous belt conveyor direction, reducing the flow and accumulation of paint layer under gravity, resulting in dripping and affecting product quality.

[0016] 3. The alternating short and long shaft design avoids interference between adjacent clamping components, improves equipment space utilization, and can carry 30% more workpieces with the same synchronous belt length. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0020] Please see Figure 1-5The present invention provides a technical solution: a multi-process integrated processing system for display bracket components, including a feeding mechanism, a punching mechanism, a painting mechanism, a drying mechanism, and a transfer mechanism. The feeding mechanism includes a loading platform 11, a hopper 12 for storing workpieces 5, and a pushing component. The punching mechanism includes a punch press 21, on which a punching area is provided. The pushing component is used to push the workpieces 5 in the hopper 12 to the punching area. The drying mechanism includes a drying chamber 4, in which a partition 403 is provided to divide the drying chamber 4 into a drying chamber 402 and a painting chamber 401. The painting mechanism is located in the painting chamber 401, and a clamping component for holding the workpieces 5 is provided in the painting chamber 401. The clamping component can move repeatedly within the painting chamber 401 and the drying chamber 402 to complete the painting and drying processes. The drying chamber 402 has a sealed door on the outside, which is hidden in the figure for easy display. The transfer mechanism is used to transfer the workpieces 5 that have completed the punching process from the punching area to the clamping component.

[0021] The hopper 12 stores stacked workpieces 5. A door on one side of the hopper 12 facilitates the placement of workpieces 5. A pushing assembly precisely pushes the workpieces 5 from the hopper 12 to the punching area of ​​the punch press 21. After punching, a transfer mechanism is activated, moving the workpieces 5 to a clamping assembly in the spray painting chamber 401 of the drying chamber 4. The clamping assembly then moves repeatedly between the spray painting chamber 401 and the workpieces 5, sequentially completing the painting and drying processes. This device achieves seamless integration of feeding, punching, painting, and drying processes, significantly reducing manual intervention between processes. The clamping assembly secures the workpieces 5 within the spray painting chamber, and after painting, they are directly transported to the drying chamber 4 for drying, eliminating the need for additional transfer and preventing contact with the undried paint surface of the workpieces 5 during transport, which could damage the paint and affect the product's appearance.

[0022] The hopper 12 is located on the top surface of the loading platform 11. Several workpieces 5 are stacked inside the hopper 12. A through groove 13 is opened at the bottom of the hopper 12. The depth of the through groove 13 is between 1.2 and 1.8 times the height of the workpiece 5. The hopper 12 and the base of the punch press 21 are flush and fit together. The pushing assembly includes a first cylinder 14 located on one side of the through groove 13 in the X-axis direction. The movable end of the first cylinder 14 is provided with a push plate 15 for pushing the workpiece 5 to the punching area.

[0023] Under the influence of gravity, the bottommost workpiece 5 stacked in the hopper 12 falls into the through-slot 13, whose bottom depth is 1.2 to 1.8 times the height of the workpiece 5. This depth design ensures that only one workpiece 5 is pushed at a time and avoids workpiece 5 getting stuck. Then, the first cylinder 14 drives the push plate 15 along the X-axis of the through-slot 13 to smoothly push the workpiece 5 in the slot to the punching area. The thickness of the push plate 15 plus the thickness of the workpiece 5 is greater than the depth of the through-slot 13, preventing the push plate 15 from bringing out the next workpiece 5 during the retraction process. This structure eliminates the need for manual loading of each workpiece, reducing labor costs, avoiding the jamming problem caused by pushing multiple workpieces 5 at the same time, and improving the automation and stability of the feeding process.

[0024] First limiting strips 22 are symmetrically arranged on both sides of the punching area along the Y-axis. The two first limiting strips 22 extend along the X-axis and fit against the discharge end of the hopper 12. The distance between the two first limiting strips 22 matches the length of the workpiece 5 to guide and limit the movement direction of the workpiece 5. A second limiting strip 23 is arranged on the side of the punching area away from the first cylinder 14 to limit the movement stroke of the workpiece 5. A pressure sensor is arranged between the first cylinder 14 and the push plate 15.

[0025] During the pushing process of workpiece 5 by pusher plate 15, the first limiting strips 22 on both sides guide the workpiece 5 according to the spacing matching the length of workpiece 5, preventing workpiece 5 from deviating. When workpiece 5 touches the second limiting strip 23, its movement stroke is restricted, ensuring accurate positioning in the punching area. At the same time, the pressure sensor between the first cylinder 14 and pusher plate 15 monitors the pushing pressure in real time. By analyzing and comparing the cylinder stroke and the pressure sensor data, the system can ensure that the cylinder will not extend further when workpiece 5 is pushed to contact the second limiting strip 23, and can also promptly provide feedback and stop the machine in case of abnormal pressure such as workpiece 5 jamming, avoiding damage to the equipment or workpiece 5. The above device further improves the positioning accuracy of workpiece 5 in the punching area, ensures the accuracy of hole positions in subsequent punching processing, enhances the safety of equipment operation, reduces downtime due to failure, and improves the overall reliability of processing.

[0026] The punching area has through holes corresponding to the position and size of the punch, which are used for the punch to pass through to complete the punching operation and discharge waste. At least two rotary clamping cylinders 24 are arranged around the outside of the punching area. The ends of the rotary clamping cylinders 24 are fixedly connected to the downward-facing pressure blocks 25 by connecting rods. The bottom surface of the pressure blocks 25 is provided with rubber pads.

[0027] After workpiece 5 is positioned, the four clamping cylinders surrounding the punching area activate, driving the pressure block 25 to rotate above workpiece 5 and press it downwards via the connecting rod. The rubber pad on the bottom of the pressure block 25 increases friction and prevents damage to the surface of workpiece 5. The punch then moves downwards, passing through a through hole corresponding to its position and size to complete the punching. Waste material is discharged directly through the through hole. Using the rotary clamping cylinder 24 to clamp and fix workpiece 5 avoids displacement deviation during punching. The rubber pad protects the surface finish of workpiece 5, and waste material is discharged promptly to prevent accumulation and affect processing, significantly improving the accuracy, quality, and efficiency of the punching process. When the rotary clamping cylinder 24 is clamping workpiece 5, the pressure block 25 is positioned above workpiece 5. After punching is completed, the rotary clamping cylinder 24 first extends and then rotates to move the pressure block 25 to the outside of workpiece 5, preventing the rotary clamping cylinder 24 from interfering with the transfer mechanism.

[0028] The transfer mechanism includes a guide rail 36 arranged along the Y-axis and a lifting platform 31 slidably connected to the guide rail 36. The lifting platform 31 can move stably along the guide rail 36. A turntable 32 is rotatably arranged on the top surface of the lifting platform 31. A first motor for driving the turntable 32 to rotate is arranged inside the lifting platform 31. A fixed plate 33 facing the punch press 21 is fixedly arranged on the turntable 32. A connecting plate 34 is hinged to the end of the fixed plate 33 away from the turntable 32. The connecting plate 34 is initially parallel to the fixed plate 33, and at least two pneumatic suction cups are evenly arranged on the bottom surface of the connecting plate 34. The paint spraying chamber 401 is located on one side of the transfer mechanism along the Y-axis. The transfer mechanism transfers the workpiece 5 from the punching area to the clamping assembly of the paint spraying chamber 401 through lifting, translation and rotation actions.

[0029] After workpiece 5 is punched, the lifting platform 31 of the transfer mechanism moves along the Y-axis guide rail 36 to above the punching area. The height is adjusted so that the pneumatic suction cup on the bottom surface of the connecting plate 34 adheres to workpiece 5 and generates negative pressure adsorption. Then, the lifting platform 31 rises, and the turntable 32 rotates under the drive of the first motor, causing the fixing plate 33 and connecting plate 34 to turn towards the spray booth 401. Then, the second motor 35 drives the connecting plate 34 to rotate 90 degrees. Finally, the lifting and translation of the lifting platform 31 transfers workpiece 5 to the clamping assembly. The negative pressure is then released, and workpiece 5 is stably placed on the clamping assembly. This device achieves non-destructive gripping and precise transfer of workpiece 5 through the coordinated actions of the guide rail 36 translation and the lifting platform 31 height adjustment, combined with the negative pressure adsorption principle of the pneumatic suction cup. The hinged connecting plate 34 allows for fine-tuning of the placement angle. The entire transfer process is fully automated, requiring no manual handling and avoiding damage and contamination of workpiece 5 during transfer. Multi-action coordination ensures precise transfer of workpiece 5 to the clamping assembly, efficiently connecting the punching and painting processes and further enhancing the overall processing continuity. In the above process, the lifting platform 31 slides along the guide rail 36 via a lead screw mechanism (not shown in the figure), ensuring accurate stroke with minimal error.

[0030] A slot 404 extending through its thickness is provided on the partition plate 403. A synchronous belt 411 extending through the slot 404 is provided in the drying chamber 4. A synchronous pulley 412 is rotatably provided at each of the four corners of the synchronous belt 411. One of the synchronous pulleys 412 is connected to the drive motor. Several mounting blocks 413 are spaced along the length of the synchronous belt 411. A through slot extending through the Y-axis is provided on the mounting block 413. A rotating shaft 414 is rotatably provided in the through slot through a bearing. A clamping assembly is fixedly provided at the end of the rotating shaft 414 facing the transfer mechanism. The clamping assembly includes a mounting plate 415 fixedly connected to the rotating shaft 414 and fixing rods 416 evenly provided on the mounting plate 415. The position and number of fixing rods 416 correspond to the preset holes on the workpiece 5. The workpiece 5 is positioned and clamped by fitting it onto the fixing rods 416 through the holes.

[0031] When the transfer mechanism places the workpiece 5 into the clamping assembly, the workpiece 5 is fitted onto the fixing rod 416 on the mounting plate 415 through the preset holes. The position and number of the fixing rod 416 precisely correspond to the holes of the workpiece 5, achieving rapid positioning and clamping. Then, the drive motor drives the synchronous pulley 412 to rotate, causing the synchronous belt 411 to pass through the slot 404 of the partition 403, driving the mounting block 413, the rotating shaft 414, and the workpiece 5 to move. First, it stops in the spray booth 401 for painting, and then it is transferred to the drying chamber 402. This structure uses the cooperation between the holes of the workpiece 5 and the fixing rod 416 to achieve mechanical positioning. The synchronous belt 411 provides the moving power for the clamping assembly, and the slot 404 design ensures spatial connectivity between processes. The workpiece 5 can be quickly fixed, avoiding displacement during painting and drying. The synchronous belt 411 enables the cyclic movement of the clamping assembly, allowing the two processes to be connected in an orderly manner, improving the flow efficiency. Moreover, the fixing rod 416 does not obstruct the surface of the workpiece 5, ensuring the uniformity of the paint spraying.

[0032] A gear 417 is fixedly sleeved at the end of the rotating shaft 414 away from the fixed rod 416. A ring rack 418 is fixedly installed on the inner wall of the drying chamber 4 corresponding to the moving path of the synchronous belt 411. The shape of the rack is adapted to the trajectory of the synchronous belt 411. The gear 417 and the rack always maintain meshing transmission. The rotating shaft 414 includes a short shaft and a long shaft, which are alternately distributed.

[0033] When the timing belt 411 drives the clamping assembly to move, the gear 417 at the end of the rotating shaft 414 away from the fixed rod 416 always meshes with the ring rack 418 for transmission. Because the rack shape matches the trajectory of the timing belt 411, the gear 417 moves with the timing belt 411 while simultaneously driving the rotating shaft 414, the clamping assembly, and the workpiece 5 to rotate. The alternating distribution of short and long shafts avoids interference between adjacent components and further reduces the distance between two adjacent clamping assemblies, allowing for the installation of more clamping assemblies with the same length of timing belt 411. The workpiece 5 maintains continuous rotation during movement, preventing paint from flowing downwards under gravity, thus avoiding a situation where the paint layer is thicker at the bottom and thinner at the top, ensuring product quality. Inside the drying chamber 4, a first limiting plate 419 and a second limiting plate 420 in an annular shape are provided along the moving path of the synchronous belt 411. The first limiting plate 419 is located outside the second limiting plate 420. Both limiting plates are connected to the inner wall of the drying chamber 4 through a mounting bracket. An annular passage for the rotating shaft 414 to move is formed between the two limiting plates. The width of the annular passage matches the diameter of the rotating shaft 414. The inner walls of the two limiting plates are provided with a wear-resistant lubricating layer.

[0034] As the rotating shaft 414 moves and rotates with the synchronous belt 411, it remains within the annular passage formed by the first limiting plate 419 and the second limiting plate 420. The width of the passage matches the diameter of the rotating shaft 414, providing radial limiting and preventing the rotating shaft 414 from shifting. This would cause the gear 417 and the annular rack 418 to fail to mesh in a localized area, resulting in a change in the angle of the clamping assembly when it returns to its initial position after a full cycle with the synchronous belt 411. Consequently, the fixing rod 416 would not correspond to the hole on the workpiece 5, and the clamping assembly would be unable to secure the workpiece 5. The wear-resistant lubricating layer on the inner wall of the passage reduces frictional wear between the rotating shaft 414 and the limiting plates, extending the equipment's service life, reducing maintenance costs, and ensuring long-term stable operation of the equipment.

[0035] Several air pipes (not shown in the figure) are pre-embedded inside the partition 403. The air inlet ends of the air pipes are all connected to the drying air source device, and the air outlet ends are evenly distributed on the outside of the slot 404 and facing the spray booth 401. The spraying mechanism includes several movable and adjustable spray heads. The spray heads are connected to the paint supply device through pipes for uniformly spraying paint onto the surface of the workpiece 5. An air suction hood (not shown in the figure) is fixedly installed on the side of the spray booth 401 away from the partition 403. The opening of the air suction hood faces the spraying area, and the air suction hood is connected to a negative pressure machine through pipes.

[0036] During painting, the adjustable spray head receives paint from the paint supply device, adjusts its position according to the workpiece 5, and sprays it evenly. Simultaneously, the suction hood inside the spray chamber 401 generates negative pressure under the action of a negative pressure machine, promptly removing paint mist and volatile gases to prevent pollution. The air pipes in the partition 403 face the spray chamber 401, effectively preventing gas from entering the drying chamber 402 through the slot 404, ensuring the drying chamber 402 remains as dry as possible and enhancing the drying effect. This structure improves the equipment's adaptability to workpieces 5 of different specifications. The timely removal of paint mist ensures a safe working environment and a clean workpiece surface, further improving processing efficiency and environmental friendliness. The painting mechanism described above is a common structure in this field and will not be described in detail.

[0037] Clean air that has been dried and purified is continuously discharged into the system through a circulation pipe. The circulation pipe is equipped with a filter element and several electric heating tubes are also evenly arranged inside.

[0038] After workpiece 5 enters the drying chamber 402, clean air, dried and purified by a filter, is continuously introduced through the circulation pipe to prevent contamination of workpiece 5. Simultaneously, evenly distributed electric heating elements generate heat, maintaining a stable high temperature within the drying chamber 402. Combined with the rotation of workpiece 5, the blowing of drying gas, and the circulation of clean air, rapid and uniform drying of the paint is achieved. An air inlet branch pipe is connected to the circulation pipe to prevent air from the drying chamber 402 from entering the spray painting chamber 401, which would reduce the air pressure in the drying chamber 402 and cause excessive air from the spray painting chamber 401 to enter the drying chamber 402. The electric heating elements provide a heat source, and the circulating air promotes uniform temperature distribution, synergistically accelerating paint curing. This further shortens drying time, improves product quality, and the circulating air design also achieves energy conservation and environmental protection. The clean air prevents impurity particles from appearing on the surface of workpiece 5, improving product quality.

[0039] Working process: Open the switch door on the side of the hopper 12, neatly stack the workpieces 5 to be processed into the hopper 12, and after closing the switch door, the stacked workpieces 5 will sink naturally under the action of gravity. The bottom workpiece 5 falls into the through groove 13 at the bottom of the hopper 12, and the remaining workpieces 5 are stacked on top.

[0040] The first cylinder 14 drives the push plate 15 at its movable end to move smoothly along the X-axis direction of the through groove 13. The push plate 15 pushes the workpiece 5 in the through groove 13 to move towards the punching area of ​​the punch press 21. During the transfer, the first limiting strips 22 on both sides of the punching area in the Y-axis direction guide and limit the workpiece 5 to prevent the workpiece 5 from deviating. When the end of the workpiece 5 away from the push plate 15 contacts the second limiting strip 23, the pressure sensor between the first cylinder 14 and the push plate 15 detects a sudden pressure change. Combined with the stroke of the first cylinder 14, the system immediately controls the first cylinder 14 to stop extending, and the workpiece 5 is accurately positioned at the preset position in the punching area.

[0041] After the workpiece 5 is positioned, at least two rotary clamping cylinders 24 arranged around the outside of the punching area act synchronously, driving the pressure block 25 to rotate directly above the workpiece 5 via the connecting rod. Then, the rotary clamping cylinders 24 extend downward, and the rubber pad on the bottom of the pressure block 25 adheres to the surface of the workpiece 5 and applies stable pressure to firmly fix the workpiece 5. Immediately afterwards, the punch of the punch press 21 moves downward according to the preset program, passes through the through hole corresponding to the position and size of the punch in the punching area, and completes the punching process on the workpiece 5. The metal scrap generated during processing falls directly to the scrap collection device through the through hole.

[0042] After the punching operation is completed, the rotary clamping cylinder 24 first retracts upward, then rotates in the opposite direction to move the pressure block 25 to the outside of the workpiece 5. The connecting plate 34 moves to directly above the punching area. Then, the lifting platform 31 slowly descends, so that the pneumatic suction cup is in contact with the upper surface of the punched workpiece 5. The pneumatic suction cup is connected to the negative pressure source to generate suction force, and after firmly adhering to the workpiece 5, the lifting platform 31 rises to a safe height. Then, the first motor inside the lifting platform 31 drives the turntable 32 to rotate 90°, moving the fixed plate 33, the connecting plate 34, and the adsorbed workpiece. 5. The workpiece 5 is turned towards the spray painting chamber 401. At the same time, the second motor 35 drives the connecting plate 34 to rotate 90° around the hinge point, adjusting the posture of the workpiece 5 so that its preset hole position is aligned with the fixing rod 416 of the clamping assembly. Then, the lifting platform 31 moves along the guide rail 36 towards the spray painting chamber 401, aligning the preset hole position of the workpiece 5 with the fixing rod 416 on the mounting plate 415. The pneumatic suction cup releases negative pressure, and the workpiece 5 is fitted onto the fixing rod 416 through the hole, completing the positioning and clamping. The transfer mechanism then resets to the side of the punching area, waiting for the next transfer task.

[0043] The painting mechanism paints the workpiece 5 on the clamping assembly. After the painting is completed, the drive motor drives the synchronous wheel 412 to rotate slowly and drives the synchronous belt 411 to move, so that the clamping assembly moves the workpiece 5 to the drying chamber 402 for drying. During this process, the gear 417 at the end of the rotating shaft 414 is always meshed with the ring rack 418 under the restriction of the first limiting plate 419 and the second limiting plate 420. Therefore, the workpiece 5 will also rotate during the movement to avoid the phenomenon of dripping. After one cycle, the dried workpiece 5 returns to the painting chamber 401.
