Description

Technical Field

[0001] This invention relates to the field of card production equipment technology, specifically a card pre-packaging device. Background Technology

[0002] With the deepening of information technology development, cards containing information data and identification functions have emerged, and the demand is constantly increasing. Cards with this function generally consist of a base card and two layers of film. The base card contains an information chip, while the film can be coated with anti-counterfeiting patterns. The production process for these types of cards typically involves printing identification information onto both layers of film using an information input device, then storing them separately. After the printing and processing of both layers is complete, the base card and film are then welded together using welding equipment. The overall processing is quite cumbersome, and the connecting steps require manual assistance, which not only increases the labor intensity of operators but also affects the production efficiency of cards to some extent. Summary of the Invention

[0003] The purpose of this invention is to provide a card pre-packaging device that can print two types of film materials, one for the front and one for the back. After the film material printing is completed, it is picked up immediately and welded and packaged with the base card, which simplifies the manufacturing process and solves the problems in the prior art.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: a card pre-packaging device, including a frame, a printer on one side of the frame, a card collection box on the other side of the frame, a protective cover installed on the frame between the printer and the card collection box, and a welding station, a waste recycling station, a calibration station, a base card material box assembly, a film material temporary storage station, a film material selection and flipping mechanism, and a film material conveying mechanism arranged sequentially on the frame inside the protective cover. The welding station is closer to the card collection box, and the film material conveying mechanism is closer to the printer. A first robotic arm and a second robotic arm are also installed on the frame. The first robotic arm can move between the film material temporary storage station, the base card material box assembly, and the calibration station, and the second robotic arm can move between the calibration station, the waste recycling station, the welding station, and the... The card collection bins move between each other. The film material printed by the printer is transferred to the film material selection and flipping mechanism via the film material conveying mechanism. The film material selection and flipping mechanism can transport the unflipped or flipped film material to the film material temporary storage station. The first robot can transfer the film material and base cards in the base card material box assembly from the film material temporary storage station to the calibration station. The second robot can transfer the calibrated film material and base cards from the calibration station to the welding station. The second robot can transfer the calibrated film material and base cards from the calibration station to the waste recycling station. The welding station can perform heat sealing welding on the base cards and double-layer film material, and transfer the sealed card to the card collection bin. The film material selection and flipping mechanism includes a flipping box and a return rack. The flipping box is equipped with a rotatable film material guide frame. The turning chamber contains a first and second horizontally arranged rotating shaft, with a first conveyor belt installed between them. The turning chamber also contains a third, fourth, fifth, and sixth horizontally arranged rotating shaft, located on either side of the first conveyor belt. A second conveyor belt is installed between these shafts, bypassing the bottom of the first conveyor belt and in close contact with it. The second and first conveyor belts rotate synchronously in opposite directions. The first conveyor belt contacts the second conveyor belt on one side of the fourth rotating shaft to form a feeding channel, and the first conveyor belt contacts the second conveyor belt on one side of the third rotating shaft to form a feeding channel. The feeding channel is formed, with a first guide plate on the upper side of the first rotating shaft and a second guide plate on the upper side of the third rotating shaft. The film material can enter the feeding channel through the space between the film material guide frame and the first guide plate. After being flipped, the film material is discharged from the feeding channel and enters the return frame through the second guide plate and the film material guide frame. A paper-feeding roller is installed on the side of the return frame near the film material temporary storage position. The paper-feeding roller can rotate clockwise or counterclockwise. A pressing cylinder is installed on the side of the return frame near the flipping box. A pressing plate is installed on the piston rod of the pressing cylinder. When the film material guide frame rotates and approaches the return frame, the film material can enter the position of the paper-feeding roller through the film material guide frame. The clockwise rotation of the paper-feeding roller can drive the film material directly into the film material temporary storage position without flipping. When the film material guide frame rotates away from the return frame and the pressing cylinder drives the pressing plate to move downward,The reversing motion of the paper feed rollers drives the film material into the feeding channel under the guidance of the pressure plate and the bottom of the film material guide frame. After being flipped, the film material is discharged from the discharge channel and can re-enter the paper feed roller position through the space between the second guide plate and the bottom of the film material guide frame. The flipping box is equipped with a first motor and a second motor. The output shaft of the first motor is connected to the rotating shaft of the film material guide frame, and the output shaft of the second motor is connected to the first rotating shaft.

A positioning screw sleeve is located at the top of the adjusting plate, within which a tensioning bolt is fitted. Rotating the tensioning bolt adjusts the height of the bearing seat within the vertical movement groove. The return feed frame is equipped with a feed flare, which consists of a first inclined plate and a second inclined plate. The first inclined plate is located above the second inclined plate. The film material guide frame can rotate to the larger opening side of the feed flare. A paper feeding roller is installed at the smaller opening side of the feed flare.

A third motor is installed on the return feed frame, and the output shaft of the third motor is connected to the rotating shaft of the paper feeding roller. The pressing cylinder is installed on the first inclined plate, and the pressing plate is located between the first and second inclined plates. A tension spring is installed between the pressing plate and the cylinder body of the pressing cylinder. The tension spring always tends to pull the pressing plate away from the second inclined plate.

A pressure roller is mounted on one end of the pressure roller frame, and a clamping spring is installed between the other end of the pressure roller frame and the first inclined plate. The clamping spring always tends to press the pressure roller firmly against the paper feed roller. A lifting cylinder is also installed on the first inclined plate. A pressing plate is mounted on the piston rod of the lifting cylinder. The pressing plate can overcome the elastic force of the clamping spring and cause the pressure roller to rotate away from the paper feed roller.

Detailed Implementation

[0007] The present invention provides a card pre-packaging device, such as... Figure 1 and Figure 2As shown, the device includes a frame 1, which serves as the structure and installation base for the entire device. A printer 10 is located on one side of the frame 1, and a card collection box 11 is located on the other side of the frame 1. The printer 10 can print relevant information on the film material, and the cards made from the film material and the base card will eventually be collected in the card collection box 11.

[0008] A protective cover 12 is installed on the frame 1 between the printer 10 and the card collection box 11, providing necessary protection. Inside the protective cover 12, the frame 1 is equipped with a welding station 13, a waste material recycling station 4, a calibration station 14, a base card material box assembly 3, a film material temporary storage station 15, a film material selection and flipping mechanism 2, and a film material conveying mechanism 5, arranged sequentially. The welding station 13 is located closer to the card collection box 11, and the film material conveying mechanism 5 is located closer to the printer 10. A first robotic arm 16 and a second robotic arm 17 are also installed on the frame 1. The first robotic arm 16 can move between the film material temporary storage station 15, the base card material box assembly 3, and the calibration station 14, while the second robotic arm 17 can move between the calibration station 14, the waste material recycling station 4, the welding station 13, and the card collection box 11.

[0009] The film material printed by printer 10 can be transferred to film material selection and flipping mechanism 2 through film material conveying mechanism 5. Film material selection and flipping mechanism 2 can transport unflipped or flipped film material to film material temporary storage station 15. First robot arm 16 can transfer film material and base card in base card box assembly 3 on film material temporary storage station 15 to calibration station 14. Second robot arm 17 can transfer the calibrated film material and base card on calibration station 14 to welding station 13. Second robot arm 17 can transfer the calibrated film material and base card on calibration station 14 to waste recycling station 4. Welding station 13 can perform heat sealing welding of base card and double-layer film material, and transfer the sealed card to card collection box 11.

[0010] The film material conveying mechanism 5 can be an existing conveyor belt or conveyor roller, which feeds the printed film material into the film material selection and flipping mechanism 2. The film material selection and flipping mechanism 2 can be an existing card flipping mechanism or a flipping panel with adsorption blocks, which can adsorb and fix the film material and flip it over. The flipping operation can be selected. The film material temporary storage station 15 can be a flat plate or a platform. After printing, both flipped and unflipped film materials are sequentially fed into this station. The calibration station 14 can be an adjustment platform equipped with three axial motors. After the base card or film material is placed at this station, adaptation positioning calibration can be performed to facilitate subsequent welding and sealing. The welding station 13 can be a welding block installed on the conveyor frame that can be vertically lifted and lowered. When the two types of film materials and base cards are sequentially transferred to this station, welding and sealing can be performed. The base card material bin assembly 3 can be an existing material bin, containing base cards to be welded. The card collection box 11 can be an existing temporary storage box, containing welded and manufactured cards. Both the first robotic arm 16 and the second robotic arm 17 can be devices powered by cross-rails and using negative pressure suction connectors for gripping. Alternatively, they can be industrial robotic arms with a recognition camera and three degrees of freedom, capable of vertical lifting and lowering to grip and place cards and film materials, as well as transferring cards and film materials between workstations. The waste recycling station 4 can be an existing pull-out box, where cards and film materials that deviate during manufacturing can be placed.

[0011] The aforementioned card base material box assembly 3, welding station 13, film material temporary storage station 15, calibration station 14, card collection box 11, and waste recycling station 4 can also be the card base material box, welding station, turnover station, positioning station, finished product box, and recycling station in the printing and packaging all-in-one machine disclosed in China, patent number "CN211441623U".

[0012] The above-mentioned mechanism enables the sequential printing of two types of film materials, as well as the batch grabbing and assembly of the lower film material, base card and upper film material, and finally completes the welding and sealing, realizing the one-time production of the card.

[0013] During film material production, printing is performed in the order of one lower film material and one upper film material. This means the film material selection flipping mechanism 2 needs to sequentially flip the fed film material, sometimes flipping it and sometimes not. To achieve this function, as follows... Figure 3 As shown, the film material selection and flipping mechanism 2 includes a flipping box 20 and a return rack 21. The flipping box 20 can realize the flipping function of the film material, while the return rack 21 can select whether to send the film material into the flipping box 20. The film material sent directly by the return rack 21 to the film material temporary storage station 15 is unflipped. The film material sent into the flipping box 20 and then sent back to the film material temporary storage station 15 by the return rack 21 is flipped.

[0014] like Figure 4-8 As shown, a rotatable film material guide frame 22 is installed on the flipping box 20. The film material guide frame 22 can guide the film material, and depending on the position of the film material guide frame 22, the film material can be directly sent to the film material temporary storage station 15, or it can be first sent into the flipping box 20 for flipping and then sent to the film material temporary storage station 15.

[0015] To enable the flipping function of the film material within the flipping box 20, a first rotating shaft 23 and a second rotating shaft 24 are horizontally arranged inside the flipping box 20, with a first conveyor belt 25 installed between the first rotating shaft 23 and the second rotating shaft 24. A third rotating shaft 26, a fourth rotating shaft 27, a fifth rotating shaft 28, and a sixth rotating shaft 29 are also horizontally arranged inside the flipping box 20, with the third rotating shaft 26 and the fourth rotating shaft 27, the fifth rotating shaft 28, and the sixth rotating shaft 29 located on either side of the first conveyor belt 25. A second conveyor belt 210 is installed between the second rotating shaft 24, the third rotating shaft 26, the fourth rotating shaft 27, the fifth rotating shaft 28, and the sixth rotating shaft 29, bypassing the bottom of the first conveyor belt 25 and in close contact with it.

[0016] The second conveyor belt 210 rotates synchronously in opposite directions with the first conveyor belt 25, allowing the film material between the two conveyor belts to move and flip through mutual compression and clamping. The first conveyor belt 25 contacts the second conveyor belt 210 on one side of the fourth rotating shaft 27 to form a feeding channel, and the first conveyor belt 25 contacts the second conveyor belt 210 on one side of the third rotating shaft 26 to form a discharging channel.

[0017] A first guide plate 211 is provided on the upper side of the first rotating shaft 23, and a second guide plate 212 is provided on the upper side of the third rotating shaft 26. The film material can enter the feeding channel through the film material guide frame 22 and the first guide plate 211. The flipped film material is discharged from the discharge channel and enters the return frame 21 through the second guide plate 212 and the film material guide frame 22.

[0018] like Figure 9-12 As shown, a paper feeding roller 213 is installed on the side of the return material rack 21 near the film material temporary storage station 15. The paper feeding roller 213 can rotate forward or backward and serves as the power mechanism for feeding the film material. When the paper feeding roller 213 rotates forward, it can feed the film material into the film material temporary storage station 15. When the paper feeding roller 213 rotates backward, it can feed the film material into the flipping box 20 for flipping operation.

[0019] To guide the film material through two different conveying states, a pressing cylinder 214 is installed on the side of the return frame 21 near the flipping box 20. A pressing plate 215 is installed on the piston rod of the pressing cylinder 214. When the film material guide frame 22 rotates and approaches the return frame 21, the film material can enter the paper feed roller 213 position through the film material guide frame 22. The forward rotation of the paper feed roller 213 can drive the film material directly into the film material storage station 15 without flipping. When the film material guide frame 22 rotates away from the return frame 21 and the pressing cylinder 214 drives the pressing plate 215 to move down, the reverse rotation of the paper feed roller 213 can drive the film material into the feeding channel under the guidance of the pressing plate 215 and the bottom of the film material guide frame 22. After being flipped, the film material is discharged from the discharge channel and can re-enter the paper feed roller 213 position between the second guide plate 212 and the bottom of the film material guide frame 22.

[0020] When the membrane material turning mechanism 2 is used to transport membrane material that does not need to be turned over, such as... Figure 13 As shown, at this time, the film material guide frame 22 rotates to approach the return frame 21, the pressure plate 215 is located on the upper side of the return frame 21, the film material enters the return frame 21 through the upper part of the film material guide frame 22, and the paper feed roller 213 rotates forward to drive the film material forward until the film material is completely entered into the film material temporary storage station 15.

[0021] When the film needs to be flipped, the above-mentioned conveying process continues until the film enters the position of the paper feed roller 213. Then, the paper feed roller 213 rotates clockwise to clamp the film and stops rotating. Figure 14 As shown, the film guide frame 22 rotates away from the return frame 21, while the pressing cylinder 214 drives the pressing plate 215 to move down. The pressing plate 215 and the bottom of the film guide frame 22 form a guide, and the paper feed roller 213 rotates in the opposite direction, driving the film into the feeding channel between the film guide frame 22 and the first guide plate 211.

[0022] After entering the feeding channel, it is clamped and fed between two conveyor belts, and then discharged through the discharge channel. In the channel formed between the bottom of the second guide plate 212 and the film guide frame 22, it is fed again into the paper-feeding roller 213 position within the return frame 21. Figure 15 As shown, when the paper feed roller 213 rotates in the forward direction, it can send the film material after it has been flipped to the film material temporary storage station 15.

[0023] The film material selection flipping mechanism 2 follows the above operation process steps, and can realize the intermittent operation of film material without flipping and flipping. It is compatible with the operation of two types of film materials, upper film and lower mold. After the lower mold is printed, it can be placed on the welding station 13 by a robot after being corrected. Then, the corrected base card is placed on the lower mold, and then the corrected upper mold is placed on the base card. The assembly is completed in the order of installation, and then the subsequent welding and sealing are performed.

[0024] Furthermore, to achieve the rotational drive of the film material guide frame 22 and the synchronous reverse rotation of the first conveyor belt 25 and the second conveyor belt 210, a first motor 216 and a second motor 217 are installed on the flipping box 20. The output shaft of the first motor 216 is connected to the rotating shaft of the film material guide frame 22, and the output shaft of the second motor 217 is connected to the first rotating shaft 23. When the first motor 216 is started, it can drive the film material guide frame 22 to rotate closer to or away from the return frame 21, thereby guiding the film material to flip or not flip.

[0025] The first rotating shaft 23 extends out of the flipping box 20 and is installed with the first gear 218 and the first sprocket 219. The end of the fourth rotating shaft 27 is installed with the second gear 220 that meshes with the first gear 218. The end of the second rotating shaft 24 is installed with the second sprocket 221. A transmission chain 222 is installed between the first sprocket 219 and the second sprocket 221. The first rotating shaft 23 and the second rotating shaft 24 rotate synchronously in the same direction. The third rotating shaft 26, the fourth rotating shaft 27, the fifth rotating shaft 28 and the sixth rotating shaft 29 rotate synchronously in the same direction. The first rotating shaft 23 and the fourth rotating shaft 27 rotate synchronously in opposite directions. The second conveyor belt 210 rotates synchronously in opposite directions with the first conveyor belt 25.

[0026] After the second motor 217 starts, the first rotating shaft 23 and the second rotating shaft 24 rotate synchronously in the same direction through the power transmission of the transmission chain 222. Through the meshing of gears, they rotate in opposite directions, so that the second conveyor belt 210 on the third rotating shaft 26, the fourth rotating shaft 27, the fifth rotating shaft 28 and the sixth rotating shaft 29 rotate synchronously in opposite directions relative to the first conveyor belt 25, thereby realizing the flipping operation of the film material.

[0027] Furthermore, in order to achieve tensioning of the transmission chain 222 and ensure normal power transmission, a chain tensioning mechanism is installed on the flipping box 20. The chain tensioning mechanism includes a sector plate 223. The sector plate 223 is mounted on the flipping box 20 at its axial center position by a positioning bolt 224. An arc groove 225 is also provided on the sector plate 223. A clamping bolt 226 is fitted in the arc groove 225. A third sprocket 227 and a fourth sprocket 228 are provided between the positioning bolt 224 and the clamping bolt 226. The third sprocket 227 and the fourth sprocket 228 are respectively engaged on both sides of the transmission chain 222.

[0028] The positioning bolt 224 serves as the rotation center of the sector plate 223 and remains relatively stationary. By loosening the clamping bolt 226, the sector plate 223 can rotate and adjust under the guidance of the arc groove 225. The third sprocket 227 and the fourth sprocket 228 located on both sides of the transmission chain 222 will rotate and tighten the chain to prevent the chain from being too loose and causing transmission problems.

[0029] Furthermore, to achieve tensioning of the two conveyor belts within the flipping box 20, a conveyor belt tensioning mechanism is installed on the flipping box 20. This mechanism includes an adjusting baffle 229 capable of vertically moving up and down on the flipping box 20. A bearing seat 230, which mates with a rotating shaft, is installed within the adjusting baffle 229. A vertical shift groove 231, which mates with the bearing seat 230, is provided on the flipping box 20. The adjusting baffle 229 can drive the bearing seat 230 and the internal rotating shaft to move vertically up and down within the vertical shift groove 231, thereby tensioning the conveyor belts.

[0030] To adjust the vertical position of the adjusting baffle 229, a positioning screw sleeve 232 is provided on the upper part of the adjusting baffle 229. A tensioning bolt 233 is installed inside the positioning screw sleeve 232. The screw of the tensioning bolt 233 is pressed against the horizontal plate of the adjusting baffle 229. Rotating the tensioning bolt 233 can adjust the height position of the bearing seat 230 in the vertical moving groove 231.

[0031] Furthermore, to facilitate the feeding of the film material via the film material guide frame 22 to the paper feed roller 213, the return frame 21 is provided with a feeding flare, which consists of a first inclined plate 234 and a second inclined plate 235, with the first inclined plate 234 located above the second inclined plate 235. The film material guide frame 22 can rotate to the side with the larger opening of the feeding flare, and can also rotate to the side with the larger opening away from the feeding flare.

[0032] When the film material does not need to be flipped and is directly fed into the temporary storage position, the film material guide frame 22 rotates to align with the large opening side of the feed horn, and the film material will directly enter the paper feed roller 213. Forward rotation will send the unflipped film material into the temporary storage position. When the film material needs to be flipped, after the film material is fed into the paper feed roller 213, the film material guide frame 22 rotates away from the large opening side of the feed horn, the pressure plate 215 descends accordingly, the paper feed roller 213 rotates in the opposite direction, and the film material guide frame 22 guides the retreating film material, allowing the film material to enter the flipping box 20 for subsequent flipping operations.

[0033] A paper-feeding roller 213 is installed on one side of the small opening of the feed flare. A paper-pressing roller 236 is installed on the return frame 21 above the paper-feeding roller 21. Through the squeezing and relative rotation of the paper-feeding roller 213 and the paper-pressing roller 236, the film material can be clamped and conveyed. The paper-pressing roller 236 can rotate to move closer to or away from the paper-feeding roller 213. A third motor 237 is installed on the return frame 21. The output shaft of the third motor 237 is connected to the rotating shaft of the paper-feeding roller 213. When the third motor 237 is started, it can drive the paper-feeding roller 213 to rotate forward or backward, thereby conveying the film material.

[0034] To avoid affecting the forward conveying of the film material within the feed flare and its reverse entry into the turning box 20, the pressing cylinder 214 is mounted on the first inclined plate 234, and the pressing plate 215 is located between the first inclined plate 234 and the second inclined plate 235. A tension spring 238 is installed between the pressing plate 215 and the cylinder body of the pressing cylinder 214. The tension spring 238 always tends to pull the pressing plate 215 away from the second inclined plate 235. The extension of the piston rod of the pressing cylinder 214 can overcome the elastic force of the tension spring 238 to move the pressing plate 215 downward. The tension spring 238 allows the pressing plate 215 to move upward and reset in time, without interfering with the subsequent conveying of the film material.

[0035] The pressure plate 215 and the rotated film guide frame 22 can guide the film material into the turning box 20. In order to avoid interference between the film guide frame 22 and the pressure plate 215 during the rotation, a rotation clearance groove 239 that cooperates with the pressure plate 215 is also provided on the film guide frame 22.

[0036] When the film material gets clogged between the paper feed roller 213 and the paper pressure roller 236, the machine can be stopped and the paper pressure roller 236 can be adjusted to rotate away from the paper feed roller 213. The film material can be manually removed, and then the paper pressure roller 236 can be readjusted to rotate closer to the paper feed roller 213 to ensure the normal delivery of subsequent film material.

[0037] To achieve the above functions, a rotatable pressure roller frame 240 is hinged to the first inclined plate 234. A paper-pressing roller 236 is installed at one end of the pressure roller frame 240, and a compression spring 241 is installed between the other end of the pressure roller frame 240 and the first inclined plate 234. The compression spring 241 always tends to press the paper-pressing roller 236 against the paper-feeding roller 213. The paper-feeding roller 213 and the paper-pressing roller 236 can always remain in a closed state under the action of the compression spring 241, and can elastically float according to the thickness of the film material itself.

[0038] Furthermore, to allow the pressure roller 236 to rotate away from the paper feed roller 213, a lifting cylinder 242 is also installed on the first inclined plate 234. A pressing plate 243 is installed on the piston rod of the lifting cylinder 242. When the piston rod of the lifting cylinder 242 extends, the pressing plate 243 can overcome the elastic force of the compression spring 241, causing the pressure roller 236 to rotate away from the paper feed roller 213. In actual long-term testing and improvement, the lifting cylinder 242 can also be omitted. When the lifting cylinder 242 is not installed, an air nozzle fixing seat can be installed at the original mounting position to blow high-pressure gas onto the film material at the bottom, preventing the film material from warping upwards during the conveying process and allowing the film material to enter the next process along the preset track.

[0039] Furthermore, in order to achieve storage within the base card hopper assembly 3, and to allow the base cards located at the bottom of the base card hopper assembly 3 to be moved upwards and fed in after a portion of the base cards have been removed, such as... Figure 16 and Figure 17 As shown, the base card material box assembly 3 includes a base card material box 30, inside which is installed a base card tray 31 that can be vertically lifted and lowered. The base card tray 31 is used to place stacks of base cards to be welded. The first robot arm 16 can descend onto the base card tray 31, and the base card tray 31 can drive the base cards on it to move up and down synchronously to ensure that the first robot arm 16 can pick up the base cards on the base card tray 31. A blowpipe 329 is installed at the top of the base card material box 30. The blowpipe 329 can blow gas horizontally to the upper side of the base card material box 30. The blowpipe 329 can be connected to an air supply source through an air line connector. The blown gas can cause other base cards that are electrostatically attracted to the bottom of the grasped base card to fall off, ensuring that only one base card is grasped at a time.

[0040] To facilitate the removal of the base card hopper 30 and the replenishment of the base cards inside, a positioning and pulling mechanism is installed between the base card hopper 30 and the frame 1. The positioning and pulling mechanism can drive the base card hopper 30 to move in and out relative to the frame 1. The positioning and pulling mechanism can be an existing guide rail slider mechanism on both sides of the drawer, with a drive motor to realize the automatic pulling of the base card hopper 30, or it can be a matching guide sleeve and guide rod, which realizes the automatic pulling of the base card hopper 30 through an electric push rod.

[0041] Furthermore, in order to achieve the vertical lifting and lowering of the baseplate 31, such as Figure 18 and Figure 19 As shown, a fourth motor 32 is installed at the bottom of the base card material box 30, and a vertically arranged lead screw 33 is installed on the rear side of the base card material box 30. The output shaft of the fourth motor 32 is connected to the rotating shaft of the lead screw 33. A support plate 34 is provided at the bottom of the base card support plate 31, and a lifting groove 35 that cooperates with the support plate 34 is provided on the base card material box 30. A lifting block 36 is provided at one end of the support plate 34 that extends out of the lifting groove 35. A lead screw nut 37 that cooperates with the lead screw 33 is installed on the lifting block 36. A lifting slide rail 38 is installed on the rear side of the base card material box 30, and a lifting slider 39 that cooperates with the lifting slide rail 38 is provided on the lifting block 36.

[0042] After the fourth motor 32 is started, it can drive the lead screw 33 to rotate, thereby realizing the vertical movement of the lead screw nut 37 and the lifting block 36. The cooperating lifting slide rail 38, lifting slider 39, support plate 34 and lifting groove 35 can provide necessary guidance for the vertical lifting of the base card tray 31, ensuring the stable vertical lifting of the base card tray 31 in the base card box 30.

[0043] Furthermore, in order to ensure the stability of the base card box 30 during the pulling process and to avoid shaking when the base card box 30 is pulled, the positioning and pulling mechanism includes a primary linear bearing mechanism disposed on one side of the base card box 30 and a secondary linear bearing mechanism disposed on the other side of the base card box 30.

[0044] like Figure 20-23 As shown, the primary linear bearing mechanism includes a linear guide rail 310 mounted on the frame 1, and a linear slider 311 that mates with the linear guide rail 310 mounted on the base material box 30. The secondary linear bearing mechanism includes a fixed folding plate 312 mounted on the frame 1, with a primary guide rail 313 connected to the bottom of the horizontal plate of the fixed folding plate 312. Two sets of primary sliders 314 are mounted on the bottom of the primary guide rail 313. Secondary guide rails 315 are connected to the bottom of the two sets of primary sliders 314, and two sets of secondary sliders 316 are mounted on the bottom of the secondary guide rails 315. The two sets of secondary sliders 316 are fixedly connected to the base material box 30.

[0045] The primary slide rail 313 has a primary limiting plate 317 installed at its end, which restricts the movement of the primary slider 314 on the primary slide rail 313. The secondary slide rail 315 has a secondary limiting plate 318 installed at its end, which restricts the movement of the secondary slider 316 on the secondary slide rail 315. The limiting plates prevent the slider from moving off the slide rail.

[0046] A fifth motor 319 is installed on the vertical plate of the fixed folding plate 312. A drive pulley 320 is installed on the output shaft of the fifth motor 319. A driven pulley 321 is installed on the vertical plate of the fixed folding plate 312. A pull-out conveyor belt 322 is installed between the drive pulley 320 and the driven pulley 321. The pull-out conveyor belt 322 is fixedly connected to two sets of secondary sliders 316. When the fifth motor 319 is started, it can drive the base card box 30 to move in and out relative to the frame 1.

[0047] The addition of two sets of sliders increases the overall length spacing of the sliding mechanism, which improves the stability of the base card box 30 during the sliding process, enhances the load-bearing strength of the secondary linear bearing mechanism, and extends the pull-out length of the base card box 30 to a certain extent, facilitating subsequent replenishment or replacement of base cards.

[0048] Furthermore, in order to limit the forward and backward movement of the base card box 30 during the pulling process, a synchronization plate 323 is installed between the two sets of secondary sliders 316 and the pulling conveyor belt 322. A detection rod 324 is installed on the lower side of the synchronization plate 323. The detection rod 324 can move synchronously with the base card box 30. By measuring the position of the detection rod 324 in real time, the pulling limit of the base card box 30 can be achieved by controlling the fifth motor 319.

[0049] A sensor bracket 325 is provided at the bottom of the vertical plate of the fixed folding plate 312. One end of the sensor bracket 325, inside the frame 1, is equipped with an origin position sensor 326 and a second position sensor 327. The other end of the sensor bracket 325 is equipped with a first position sensor 328. When the detection rod 324 moves to the first position sensor 328, the base card hopper 30 is pulled out of the frame 1. When the detection rod 324 moves to the origin position sensor 326, the base card hopper 30 enters the frame 1. When the detection rod 324 moves to the second position sensor 327, the base card hopper 30 reaches its limit position within the frame 1.

[0050] Under the combined guidance of the primary and secondary linear bearing mechanisms, the base card hopper 30 can stably move and be pulled along the frame 1. The fifth motor 319 starts, driving the pulling conveyor belt 322 to rotate, and the secondary slider 316 moves synchronously, allowing the base card hopper 30 to be pulled out relative to the frame 1 for subsequent base card replenishment. After replenishment, the fifth motor 319 reverses, pulling the base card hopper 30 back into the frame 1 for subsequent retrieval by the robotic arm. During the pulling process, the origin position sensor 326, the first position sensor 328, and the second position sensor 327 monitor and limit the movement of the base card hopper 30, preventing derailment.

[0051] Furthermore, to facilitate the unified recycling of discarded base cards or membrane materials, such as Figure 24-27 As shown, the waste recycling station 4 includes a frame 40 set on the frame 1, and a pull-out waste bin 41 is installed inside the frame 40. The frame 40 serves as a connector, and the waste bin 41 inside is used to hold waste base cards or membrane materials.

[0052] To facilitate the subsequent processing of the waste base cards or film materials stored inside the waste bin 41, a pull-out slide rail 42 is installed at the bottom of the bin frame 40, and a pull-out sliding plate 43 that cooperates with the pull-out slide rail 42 is provided at the bottom of the waste bin 41, so that the waste bin 41 can be pulled out from the frame 1.

[0053] A frame plate 44 is installed on the upper side of the waste bin 41. Inside the frame plate 44 is a cover plate 45 that can be rotated and opened. When the robotic arm needs to feed waste base cards or film materials into the waste bin 41, the cover plate 45 will rotate and open, revealing the waste bin 41 at the bottom. When there are no waste base cards or film materials and the device is performing normal card production, the cover plate 45 is in the rotated closed state to prevent interference with the normal card production process.

[0054] To enable the cover plate 45 to rotate and open, a first locking block 46 is provided at each of the four corners of the bottom of the cover plate 45. A second locking block 47, corresponding to the first locking block 46, is provided at the bottom of the frame plate 44. A short rotating plate 48 is hinged between the corresponding first locking block 46 and second locking block 47 on one side, and a long rotating plate 49 is hinged between the corresponding first locking block 46 and second locking block 47 on the other side. A slot 410 is provided on the frame plate 44 to mate with the first locking block 46. A telescopic cylinder 411 is installed on the frame plate 44, and the piston rod of the telescopic cylinder 411 is hinged to the long rotating plate 49. The extension and retraction of the piston rod of the telescopic cylinder 411 can drive the cover plate 45 to rotate and open relative to the frame plate 44.

[0055] The locking block is designed to increase the connection strength of the rotating plate and also to position the rotating plate inside the cover plate 45, allowing it to enter the slot in the frame plate 44. The slot 410 on the frame plate 44 is designed to prevent interference between the locking block and the frame plate 44 during rotation, and to allow the cover plate 45 to rotate and fit within the frame plate 44, thus improving the stability of the cover plate 45 in the locked and closed state to a certain extent.

[0056] Furthermore, in order to transport the film material printed by printer 10 to the film material selection and flipping mechanism 2, such as... Figure 28 and 29 As shown, the film material conveying mechanism 5 includes a support base 50, a conveyor frame 51 is installed on the support base 50, a number of conveyor rollers 52 are installed inside the conveyor frame 51, and a conveyor belt 53 is installed around the outer periphery of the conveyor rollers 52. The conveyor belt 53 is located between the outlet of the printer 10 and the inlet of the film material selection and flipping mechanism 2, and the film material can be transferred on the conveyor belt 53.

[0057] To drive the rotation of the conveyor belt 53, a sixth motor 54 is provided inside the conveyor frame 51. A first conveyor belt pulley 55 is installed on the output shaft of the sixth motor 54. A second conveyor belt pulley 56 is installed at one end of the conveyor roller 52 that extends out of the conveyor frame 51. A conveyor belt 57 is installed between the first conveyor belt pulley 55 and the second conveyor belt pulley 56. When the sixth motor 54 is started, it can drive the conveyor belt 53 to rotate, thereby realizing the conveying of the film material on it.

[0058] A film material pressure roller 58 is installed on the conveyor frame 51 near the film material selection and flipping mechanism 2. The film material pressure roller 58 is set in correspondence with the conveyor roller 52. The film material enters the film material selection and flipping mechanism 2 between the film material pressure roller 58 and the conveyor belt 53. The film material pressure roller 58 can perform preliminary compression on the film material and prevent the film material from falling off the conveyor belt 53.

[0059] The conveyor belt 53 has a perforation 59, and a fan 510 is installed inside the conveyor frame 51. The fan 510 can blow air upwards. The perforation 59, together with the setting of the perforation 59, can prevent the film material from sticking to the conveyor belt 53 due to electrostatic adhesion and being unable to fall off, ensuring that the film material can be conveyed to the film material selection and flipping mechanism 2.

[0060] Furthermore, in order to achieve tensioning of the conveyor belt 53, a conveyor belt tensioning mechanism is installed between the conveyor roller 52 and the conveyor frame 51, such as... Figure 30 As shown, the conveyor belt tensioning mechanism includes an inner groove 511 formed on the conveyor frame 51. Tensioning columns 512 that cooperate with the inner groove 511 are installed at both ends of the conveyor roller 52. Tensioning studs 513 are installed in the inner groove 511. Through holes for the tensioning studs 513 are formed on the tensioning columns 512. Tensioning nuts 514 are installed on the outer periphery of the tensioning studs 513 on the upper side of the tensioning column 512. Rotating the tensioning nuts 514 can push the tensioning columns 512 to move closer to the conveyor belt 57, that is, push the conveyor roller 52 to tighten the conveyor belt 57. Then, by rotating the tensioning nuts 514, the conveyor belt 57 is tightened, ensuring the normal rotation of the conveyor belt 57 and completing the normal conveying of the film material.

[0061] Furthermore, the protective cover 12 includes a first protective cover 18 arranged horizontally and a second protective cover 19 arranged vertically. The first protective cover 18 is located on the outer periphery of the welding station 13, the waste recycling station 4, the calibration station 14, the base card material box assembly 3 and the film material temporary storage station 15. The second protective cover 19 is located on the outer periphery of the film material selection and flipping mechanism 2 and the film material conveying mechanism 5. The first protective cover 18 is provided with two symmetrically arranged casement windows 110, and the second protective cover 19 is equipped with a protective door 111 that can be rotated and opened.

[0062] Welding station 13, waste recycling station 4, calibration station 14, base card material box assembly 3, and membrane material temporary storage station 15 are all located within the frame 1. Waste recycling station 4 and base card material box assembly 3 can be pulled out relative to the frame 1. The transfer of base cards and membrane materials between these stations is achieved via the first robotic arm 16 and the second robotic arm 17. Since the frame 1 requires lateral space for movement, the first protective cover 18 is arranged laterally. Due to the need for flipping, the membrane material needs to be moved vertically downwards and undergo its own bending and flipping. The flipping mechanism 2 requires a certain amount of vertical space, so the second protective cover 19 is arranged vertically. The casement window 110 and protective door 111 are provided to facilitate observation, inspection, and maintenance of the various stations within the device.

[0063] Furthermore, to achieve the gripping and placement of membrane material and base card during use, this device employs negative pressure suction and jet blowing methods. The structure adopted to achieve the above functions is as follows: Figure 32As shown, a first air pump 112 and a second air pump 113 are installed on the frame 1. These air pumps serve as air sources and can directly generate compressed gas in an atmospheric pressure environment. Both the first robotic arm 16 and the second robotic arm 17 are equipped with suction cups 114. Each suction cup 114 contains an air extraction pipe 115 and an air jet pipe 116. The air extraction pipe 115 draws air from the suction cup 114 to create a negative pressure, thus gripping the material. The air jet pipe 116 ejects gas, allowing the material to fall and be placed under the influence of the airflow when the air extraction pipe 115 stops drawing air. The first air pump 112 is connected to the jet pipe 116 and the blow pipe 329 via air passages, and the second air pump 113 is connected to the suction pipe 115 via air passages. Each air passage is equipped with a solenoid valve to control the on / off state of the air passage. The first air pump 112 can provide high-pressure gas to blow out at high speed to complete the falling and placement of materials, while the second air pump 113 can realize negative pressure suction to complete the grabbing of materials. The on / off state of the gas can be controlled by the solenoid valves on their respective air passages to realize the grabbing and placement of materials respectively.
