Description

Technical Field

[0001] This utility model relates to the technical field of optical silver transfer card production equipment, specifically a positioning and flipping device for optical silver transfer card spraying. Background Technology

[0002] Optical silver transfer cards, as functional cards integrating optical silver layer transfer technology, are widely used in financial payments, identity verification, anti-counterfeiting and traceability fields such as bank cards, social security cards, and high-end membership cards. The surface of these cards typically requires precision spraying to impart wear resistance, corrosion resistance, and scratch resistance, while optimizing the visual effect and durability of the optical silver layer. The quality of the spraying directly affects the card's appearance consistency, lifespan, and functional stability; therefore, stringent requirements are placed on the positioning accuracy, flipping reliability, and automation level of the spraying process.

[0003] Traditional positioning and flipping devices for optical silver transfer card coating often rely on manual flipping or simple mechanical gripping. Manual flipping not only increases labor costs but also easily causes contamination and scratches on the card surface due to hand contact during the flipping process, or deformation of the card due to uneven force. Existing mechanical flipping devices suffer from problems such as unstable gripping and easy detachment, and inaccurate secondary positioning due to flipping angle deviation. This results in the card position after flipping being offset from the initial positioning, causing the two sides of the coating area to not correspond, which seriously affects product quality. Therefore, those skilled in the art provide a positioning and flipping device for optical silver transfer card coating to solve the problems mentioned in the background art. Utility Model Content

[0016] Please see Figures 1-5In this embodiment of the present invention, a positioning and flipping device for spraying a silver transfer card includes a base plate 1. Two sliding grooves 2 are formed on the upper surface of the base plate 1. Two sets of first bearings 3 are fixedly embedded in the inner walls of each sliding groove 2. Threaded rods 4 are fixedly connected to the inner rings of each set of first bearings 3. Sliding blocks 5 are slidably connected inside each sliding groove 2. The outer surfaces of the two threaded rods 4 are threadedly connected to the sliding blocks 5. Fixing plates 6 are fixedly connected to the upper surfaces of each sliding block 5. Second bearings 7 are fixedly embedded in the outer surfaces of each fixing plate 6. Round rods 8 are fixedly connected to the inner rings of each of the two second bearings 7. One end of each round rod 8 is fixedly... An electric telescopic rod 9 is fixedly installed. The output ends of both electric telescopic rods 9 are fixedly connected to clamping plates 10. Anti-slip pads 11 are fixedly connected to the outer surfaces of both clamping plates 10. A first rotary motor 12 is fixedly installed on the outer surface of one of the fixed plates 6. The output end of the first rotary motor 12 is fixedly connected to one end of one of the round rods 8. The round rod 8 connects the first rotary motor 12 and the clamping plate 10, transmitting torque to achieve card flipping. Its rigid structure ensures uniform force on the card during flipping, preventing deformation. The clamping plate 10 directly contacts the card for mechanical positioning. The anti-slip pads 11 increase the contact area, ensuring no slippage of the card during spraying and flipping. The anti-slip pads 11 are made of flexible anti-slip material, increasing friction between the clamping plate 10 and the card, preventing slippage, and avoiding scratches on the card surface caused by hard contact.

[0017] A second rotary motor 13 is fixedly installed on the right side of the base plate 1. Two support plates 14 are fixedly connected to the upper surface of the base plate 1. A servo motor 15 is fixedly installed on the outer surface of one of the support plates 14. Two third bearings 16 are fixedly embedded on the side of the two support plates 14 that are close to each other. A guide plate 21 is fixedly connected to the side of the two support plates 14 that are close to each other. A fixing rod 17 is fixedly connected to the inner ring of the two sets of third bearings 16. The output end of the servo motor 15 is fixedly connected to one end of one of the fixing rods 17. A transmission roller 18 is fixedly connected to the outer surface of the two sets of fixing rods 17. A conveyor belt 19 is connected to the outer surface of the two transmission rollers 18. An anti-slip silicone pad 20 is fixedly connected to the outer surface of the conveyor belt 19. The anti-slip silicone pad 20 increases the friction between the conveyor belt 19 and the card, preventing the card from slipping or shifting during the conveying process, and ensuring that the card accurately enters the positioning area. The guide plate 21 guides the card into the positioning area along a preset path, corrects the conveying deviation, avoids the card tipping over or misalignment, and improves the feeding accuracy.

[0018] A fixing post 22 is fixedly connected to the upper surface of the base plate 1. A connecting block 23 is fixedly connected to the upper surface of the fixing post 22. Two sets of suction nozzles 24 are fixedly connected to the upper surface of the connecting block 23. A spray box 25 is fixedly connected to the upper surface of the base plate 1. A display 26 is fixedly installed on the outer surface of the spray box 25. A paint tank 27 is fixedly connected to the upper surface of the spray box 25. A material pump 28 is fixedly installed on the upper surface of the paint tank 27. A material pump 28 is fixedly connected to the input end of the material pump 28 via a material suction pipe 29. One end of the material suction pipe 29 is fixedly connected to the upper surface of the spray box 25. The output end of the material pump 28 is fixedly connected to... There is a material conveying pipe 30, and the output end of the material conveying pipe 30 is fixedly connected to a spraying pipe 31. One end of the spraying pipe 31 is fixedly connected to the spraying box 25. The suction nozzle 24 temporarily stores the card through negative pressure to avoid surface contamination caused by manual contact. At the same time, it provides a stable transition for the clamping plate 10 to hold the card and improve the stability of material feeding. The display 26 displays the equipment operating parameters in real time, such as rotation speed, clamping force, and spraying volume, so that the operator can monitor the status, find and eliminate faults in time. The spraying pipe 31 accurately sprays the paint, and with the positioning device, it achieves uniform spraying on the card surface, ensuring that the coating thickness is consistent and improving the product appearance quality.

[0019] The working principle of this utility model is as follows: First, the servo motor 15 drives the fixed rod 17 to rotate through the third bearing 16, which in turn drives the transmission roller 18 and the conveyor belt 19 to operate. The anti-slip silicone pad 20 prevents the card from slipping, and the guide plate 21 guides the card to be accurately delivered above the fixed column 22. The suction nozzle 24 on the connecting block 23 temporarily stores the card. Next, the second rotary motor 13 drives the threaded rod 4 in the sliding groove 2 to rotate through the first bearing 3, causing the sliding block 5 to drive the fixed plate 6 to move laterally to adapt to different card widths. After reaching the correct position, the electric telescopic rod 9 pushes the clamping plate 10 and the anti-slip pad 11 to clamp the card, and the round rod 8 supported by the second bearing 7 achieves initial positioning. During spraying, the card is conveyed to the spraying box 25, and the suction pump 28 draws paint from the paint box 27 through the suction pipe 29 and sends it to the spraying pipe 31 through the conveying pipe 30 to complete single-sided spraying. When flipping is required, the first rotary motor 12 drives the round rod 8 to rotate 180 degrees, which drives the card to flip stably. After clamping and positioning again, the other side can be sprayed.
