[0007] The present invention discloses an automated bookmark production line that automates the steps of bookmark feeding, tassel threading, pattern engraving, box insertion, and unloading, significantly improving efficiency and reducing manual labor. At the same time, it facilitates the monitoring and management of the entire process, realizing intelligent production.

[0008] Furthermore, the feeding device includes a material tray, which has a bookmark board area for placing bookmark boards, a bookmark box area for placing bookmark boxes, and a bookmark sleeve area for placing bookmark covers; a storage rack suitable for storing the material tray; an AGV robot suitable for transporting the material tray on the storage rack to a designated location; and a feeding robot suitable for transferring the material on the material tray transported by the AGV robot to the first conveying device.

[0009] Furthermore, the engraving device includes a first laser engraving machine, positioned above the first conveying device, for engraving patterns and identification codes on the bookmark board; a first barcode scanner for recognizing the identification codes on the bookmark board; a second laser engraving machine, positioned above the second conveying device, for engraving identification codes on the bookmark sleeve; a second barcode scanner adapted to recognize the identification codes on the bookmark sleeve; a first camera for photographing the identification codes and patterns on the bookmark board; a second camera for photographing the identification codes on the bookmark sleeve; and a first rejection mechanism, electrically connected to the first camera and the first barcode scanner, for rejecting bookmark boards with unrecognizable identification codes or whose identification codes and patterns do not meet the requirements from the first conveying device.

[0010] The second rejection mechanism, electrically connected to the second camera and the second barcode scanner, is used to reject bookmark sleeves with unrecognizable identification codes or incorrectly positioned identification codes from the second conveying device.

[0011] Furthermore, the automatic bookmark production line also includes an automatic tassel hanging device, which includes a tassel distribution mechanism adapted to divide the tassels into individual pieces and convey them sequentially; and a gripping and conveying mechanism adapted to grip a single tassel and hang it onto the tassel threading device.

[0012] Furthermore, the tassel distribution mechanism includes a tassel-threading tube and a tassel-conveying assembly. Several tassels are suspended on the tassel-threading tube. The tassel-conveying assembly includes a first support, a second support, and a tassel conveyor belt mounted on the first support. The tassel conveyor belt has several conveying teeth, and a conveying groove is provided between adjacent conveying teeth. The tassel-threading tube has a receiving groove, and one end of the tassel conveyor belt extends into the receiving groove. The tassel-threading tube has a pressure plate to ensure that there is only one tassel at the same position on the tassel-threading tube, so that the tassels slide down the tassel-threading tube into the conveying groove on the tassel conveyor belt, and there is only one tassel in each conveying groove.

[0013] Furthermore, the grasping and conveying mechanism includes a moving component, the movable end of which is adapted to reciprocate along the line connecting the tassel-threading device and the tassel-distributing mechanism; and a grasping component adapted to grasp the tassels conveyed by the tassel-distributing mechanism and hang them on the tassel-threading device.

[0014] Furthermore, the moving component includes a gear transmission assembly; a support frame mounted on the second bracket; a transmission gear rotatably connected to the support frame and meshing with the output end of the gear transmission assembly; a rotating wheel coaxially connected to the transmission gear, with a rotating rod connected to the lower surface of the rotating wheel; a fixed plate mounted on the second bracket; a moving plate sliding on the fixed plate along the line connecting the tassel-threading device and the tassel-distributing mechanism, the moving plate being connected to the gripping assembly; and a compensation plate connected to the moving plate, the compensation plate having a waist-shaped groove, with the rotating rod located within the waist-shaped groove. When the transmission gear rotates, the rotating rod drives the compensation plate to reciprocate along the line connecting the tassel-threading device and the tassel-distributing mechanism, so that the gripping assembly can repeatedly grip the tassels and hang them onto the tassel-threading device.

[0015] Furthermore, the gripping component includes a movable block hinged to a movable plate. The movable block has a sliding groove, within which two clamping blocks slide. A compression spring is provided between the two clamping blocks, and a clamping hook is connected to each clamping block. The tassel conveyor belt has a hook groove along its length, the hook groove being annular and deeper than the conveyor groove.

Two guide rails are provided, both connected to a fixed block. Each guide rail includes a first straight section, an inclined section, and a second straight section connected in sequence. The second straight section is positioned near the tassel distribution mechanism. The two clamping blocks are located between the two guide rails. When the movable block moves, the two clamping blocks abut against the two guide rails under the action of the compression spring. When a clamping block abuts against the first straight section, the clamping hook is suitable for hanging the tassel on the tassel-threading device. When a clamping block abuts against the second straight section, the clamping hook is suitable for extending into the hook groove.

[0016] A production process based on the aforementioned automated bookmark production line includes the following steps: S1, a feeding device transfers bookmark boards to a first conveying device and bookmark sleeves and bookmark boxes to a boxing device; S2, a first laser engraving machine engraves patterns and identification codes on the bookmark boards, and a first barcode scanner identifies the identification codes on the bookmark boards to detect the bookmark boards. If the bookmark boards are qualified, the first conveying device continues to convey them; if the bookmark boards are unqualified, a first rejection mechanism removes the unqualified bookmark boards from the first conveying device; S3, a tassel-threading device threads tassels onto the bookmark boards; S4, a boxing device places the bookmark boards with tassels into the bookmark boxes; S5, a box-inserting device inserts the bookmark boxes containing the bookmark boards into the bookmark sleeves; S6, a unloading device sorts and unloads the bookmark sleeves containing the bookmark boxes.

[0017] Furthermore, in step S3, the boxing device moves the bookmark board with tassels to the top of the bookmark box and lowers it so that the tassels first touch the bottom surface inside the bookmark box. Then, the bookmark board moves horizontally and downwards so that the tassels are laid flat inside the bookmark box. The bookmark board is then moved horizontally again until it is in position horizontally. Finally, the bookmark board is moved downwards so that it falls into the bookmark box, thus completing the boxing of the bookmark board.

[0018] The beneficial effects of this invention are:

[0019] 1. The process of feeding, attaching tassels, carving patterns, inserting into boxes, and unloading bookmarks is automated, which greatly improves efficiency and reduces manual labor. At the same time, it facilitates the monitoring and management of the entire process, realizing intelligent production.

[0020] 2. The bookmark board and bookmark sleeve are engraved by the first laser engraving machine and the second laser engraving machine respectively, and the engraved identification code is identified by the first barcode scanner and the second barcode scanner. Finally, the bookmark board or bookmark sleeve with the identification code that cannot be identified is rejected by the first rejection mechanism and the second rejection mechanism, so as to realize the automatic detection and removal of defective products.

[0021] 3. The automatic tassel-hanging device automatically hangs the tassels onto the tassel-threading device, solving the problem of tassels being difficult to hang onto the tassel-threading device. Attached Figure Description

[0043] This invention discloses an automated bookmark production line and its manufacturing process.

[0044] Reference Figure 1 and Figure 5 An automated bookmark production line includes a first conveying device 1, a second conveying device 2, an engraving device 3, an automatic tassel-hanging device, a tassel-threading device 5, a boxing device 6, a box-inserting device 7, a feeding device 8, and a discharging device 9. The first conveying device 1 is adapted to convey bookmark boards 93, and the second conveying device 2... The device is adapted to convey bookmark sleeves with bookmark boxes 94 inserted; the engraving device 3 is adapted to engrave patterns and identification codes on the bookmark board 93 and the bookmark sleeves; the tassel-threading device 5 is adapted to thread tassels onto the bookmark board 93, the automatic tassel-hanging device is adapted to hang tassels onto the tassel-threading device 5, the boxing device 6 is adapted to place the bookmark board 93 with tassels into the bookmark box 94; the box-insertion device 7 is adapted to insert the bookmark box 94 containing the bookmark board 93 into the bookmark sleeve, and transfer the bookmark sleeve containing the bookmark box 94 to the second conveying device 2; the feeding device 8 is adapted to transfer the bookmark board 93 to the first conveying device 1, and transfer the bookmark box 94 and the bookmark sleeve to the box-insertion device 7; the unloading device 9 is adapted to sort and unload the bookmark sleeve containing the bookmark box 94.

[0045] By automating the steps of feeding, threading tassels, engraving patterns, inserting boxes, and unloading the bookmark board 93, efficiency is greatly improved and manual labor is reduced. At the same time, it is easy to monitor and manage the entire process, thus realizing intelligent production.

[0046] Specifically, refer to Figure 2 and Figure 3 The feeding device 8 includes a material tray 81, a storage rack 82, an AGV robot 83, and a feeding robot 84. The material tray 81 has a bookmark board 93 area for placing bookmark boards 93, a bookmark box 94 area for placing bookmark holders 94, and a bookmark sleeve area for placing bookmark covers. The storage rack 82 is suitable for storing the material tray 81. The AGV robot 83 is suitable for transporting the material tray 81 on the storage rack 82 to a designated position. The feeding robot 84 is suitable for transferring the material on the material tray 81 transported by the AGV robot 83 to the first conveying device 1. The feeding robot 84 can be a five-axis robotic arm.

[0047] More specifically, the storage rack 82 is fixedly connected to a first telescopic member 821, which is arranged vertically. The movable end of the first telescopic member 821 is connected to a second telescopic member 822, which is arranged horizontally. The movable end of the second telescopic member 822 is fixedly connected to a lifting plate 823. The storage rack 82, the first telescopic member 821, the second telescopic member 822, and the lifting plate 823 are all provided in two sets to support the material tray 81. When the AGV robot 83 moves to a position below the material tray 81, the material tray 81 can be placed on the AGV robot 83. Then, the movable end of the second telescopic member 822 retracts, moves upward, and then extends again, so that the lifting plate 823 is inserted below the second material tray 81 from bottom to top, and lifts the second material tray 81 and the material tray 81 above it, so that the AGV robot 83 can carry away the bottommost material tray 81.

[0048] In addition, this production line also includes an empty material tray receiving system, which is used to place the material 81 that has been transferred from the bookmark board, bookmark box and bookmark sleeve. The structure of the empty material tray receiving system is the same as that of the storage rack, so it will not be described in detail.

[0049] Specifically, refer to Figure 4 and Figure 14The engraving device 3 includes a first laser engraving machine 31, a first barcode scanner 32, a second laser engraving machine 33, a second barcode scanner 34, a first camera 37, and a second camera 38. The first laser engraving machine 31 is located above the first conveying device 1 and is used to engrave patterns and identification codes on the bookmark board 93. The first barcode scanner 32 is used to identify the identification codes on the bookmark board 93. The second laser engraving machine 33 is located above the second conveying device 2 and is used to engrave identification codes on the bookmark sleeves. The second barcode scanner 34 is suitable for identifying the identification codes on the bookmark sleeves. The first camera 37 is used to photograph the identification codes and patterns on the bookmark board 93 and compares the photographed patterns and identification codes with the standard products stored in the system to determine whether the pattern content and the position of the identification codes and patterns are correct. If they are correct, it is a good product; if they are incorrect, it is a defective product. The second camera 38 is used to photograph the identification codes on the bookmark sleeves and compares them with the standard products stored in the system to determine whether the position of the identification codes is correct. If the identification code position is correct, it is a good product; if the identification code is incorrect, it is a defective product. The first rejection mechanism 35 is electrically connected to the first camera 37 and the first barcode scanner 32, and is used to reject bookmark boards 93 with unrecognizable identification codes or identification codes and patterns that do not meet the requirements from the first conveying device 1; the second rejection mechanism 36 is electrically connected to the second camera 38 and the second barcode scanner 34, and is used to reject bookmark sleeves with unrecognizable identification codes or identification codes that are incorrectly positioned from the second conveying device 2. The identification code can be a QR code.

[0050] More specifically, the first rejection mechanism 35 includes a first rejection frame 351 and a first linear motor 352. The first rejection frame 351 is mounted on the first conveying device 1, and the first linear motor 352 is mounted on the first rejection frame 351. A third telescopic member 353 is fixedly connected to the movable end of the first linear motor 352, and a suction cup 354 is fixedly connected to the movable end of the third telescopic member 353. The movable end of the third telescopic member 353 is adapted to drive the suction cup 354 to move vertically. When the first barcode scanner 32 detects that the bookmark board 93 is unqualified, the movable end of the third telescopic member 353 moves downward, causing the suction cup 354 to adhere to the unqualified bookmark board 93. Subsequently, the movable end of the third telescopic member 353 moves upward, and the movable end of the linear motor moves, causing the unqualified bookmark board 93 to detach from the first conveying device 1.

[0051] The first conveying device 1 is equipped with a baffle 11, which is suitable for blocking the qualified bookmark board 93, preventing the bookmark board 93 from continuing to move, and thus facilitating the subsequent equipment to grab the bookmark board 93.

[0052] The second rejection mechanism 36 includes a second rejection frame 361 and a fourth telescopic member 362. The second rejection frame 361 is mounted on the second conveying device 2, and the movable end of the fourth telescopic member 362 is horizontally positioned. When the second barcode scanner 34 detects that the bookmark sleeve is defective, the movable end of the fourth telescopic member 362 extends directly, pushing the defective bookmark sleeve out of the second conveying device 2. The first conveying device 1 and the second conveying device 2 can be belt conveyors.

[0053] Furthermore, refer to Figures 5 to 11 The tassel includes an interconnected tassel hanging strap 52 and a tassel tassel 53. The tassel threading device 5 can adopt the automatic tassel threading and knotting mechanism mentioned in the background art. The tassel hanging strap 52 is suspended by a turntable 51, and the tassel hanging strap 52 is threaded onto the bookmark board 93 and knotted by the cooperation of the tassel picking mechanism, the tassel hooking mechanism and the tassel assembly mechanism.

[0054] Reference Figure 10 The boxing device 6 includes a boxing robotic arm 61 and a transfer gripper 62. Two sets of transfer grippers 62 are provided: one for picking up bookmark boards 93, and the other for picking up bookmark boxes 94 or bookmark sleeves. The end of the boxing robotic arm 61 is equipped with a quick-change connector, enabling automatic replacement of the transfer gripper 62. The transfer gripper 62 is designed according to the shape and set position of the bookmark boards 93, bookmark boxes 94, and bookmark sleeves, and achieves gripping through negative pressure adsorption. The boxing robotic arm 61 can be a five-axis robotic arm. The boxing robotic arm 61 is used to transfer the bookmark boards 93 from the first conveying device 1 to the tassel-threading device 5, and also to transfer the bookmark boxes 94 and bookmark sleeves from the material tray 81 to the box-inserting device 7. It is also used to place the tassel-threaded bookmark boards 93 onto the bookmark boxes 94. The end of the boxing robotic arm 61 is also equipped with a camera to facilitate filming the products to be gripped, enabling precise gripping.

[0055] The automatic tassel hanging device includes a tassel distribution mechanism and a gripping and conveying mechanism 42. The tassel distribution mechanism is adapted to divide the tassels into individual pieces and convey them sequentially. The gripping and conveying mechanism 42 is adapted to grip a single tassel and hang it on the turntable 51.

[0056] The tassel distribution mechanism includes a tassel tube 411 and a tassel conveying assembly. Several tassels are suspended from the tassel tube 411 by tassel suspension belts 52. The tassel conveying assembly includes a first support 412, a second support 54, and a tassel conveyor belt 413 mounted on the first support 412. Multiple conveyor rollers are rotatably connected to the first support 412. The tassel conveyor belt 413 is fitted onto the conveyor rollers and driven by them. A drive motor is also fixedly connected to the bottom of the first support 412. The output of the drive motor is connected to one of the conveyor rollers via a belt drive to drive the conveyor roller to rotate. A protective cover 4134 is provided outside the belt drive to prevent interference between the tassel suspension belt 52 and the belt drive during conveying. The robotic assembly system used in the bookmark production line has nine integrally formed conveyors 4131. Conveyor slots 4132 are provided between adjacent conveyor teeth 4131. A receiving slot 4111 is provided on the tassel tube 411. One end of the tassel conveyor belt 413 extends into the receiving slot 4111. A pressure plate 414 is fixedly connected to the tassel tube. The distance between the pressure plate 414 and the tassel tube 411 is slightly larger than the diameter of the tassel hanging strap 52, so that only one tassel hanging strap 52 can be suspended at the same position on the tassel tube 411. This allows the tassel hanging straps 52 to slide one by one along the tassel tube 411 into the conveyor slots 4132 on the tassel conveyor belt 413, with only one tassel hanging strap 52 in each conveyor slot 4132. The minimum distance between the conveyor teeth 4131 and the pressure plate 414 is less than the distance between the pressure plate 414 and the tassel tube 411, in order to separate each tassel hanging strap 52.

[0057] Specifically, the grasping and conveying mechanism 42 includes a moving component 421 and a grasping component. The movable end of the moving component 421 is adapted to reciprocate along the line connecting the tassel-threading device 5 and the tassel-distributing mechanism. The grasping component 423 is adapted to grasp the tassels conveyed by the tassel-distributing mechanism and hang them on the turntable 51 of the tassel-threading device 5. Several hanging rods 511 are arranged circumferentially on the side wall of the turntable 51 to suspend the tassel hanging straps 52. A second bracket 54 is provided below the turntable 51, and a motor is fixedly connected to the second bracket 54. The motor is fixedly connected to the turntable 51 through a drive shaft 55 to drive the turntable 51 to rotate.

[0058] More specifically, the movable component 421 includes a gear transmission assembly, a support frame 4212, a transmission gear, a rotating wheel 4214, a fixed plate 4215, a movable plate 4216, and a compensation plate 4217. The gear transmission assembly is connected to the drive shaft 55. The support frame 4212 is mounted on the second bracket 54, and the transmission gear is rotatably connected to the support frame 4212, meshing with the output end of the gear transmission assembly. The rotating wheel 4214 is coaxially and fixedly connected to the transmission gear, and a rotating rod 4218 is fixedly connected to the lower surface of the rotating wheel 4214. A fifth telescopic member 4121 is fixedly connected to the second bracket 54. The movable end of the fifth telescopic member 4121 is fixedly connected to the fixed plate 4215, and the fifth telescopic member 4121 is adapted to drive the fixed plate 4215 to move vertically. A sliding plate 422 is fixedly connected to the compensation plate 4217. A sliding groove 4221 is provided on the sliding plate 422 along the vertical direction. A sliding block 4222 is fixedly connected to the moving plate 4216. The sliding block 4222 slides in the sliding groove 4221.

[0059] The movable plate 4216 slides on the fixed plate 4215 along the line connecting the tassel-threading device 5 and the tassel-distributing mechanism, and is connected to the gripping component 423. A sliding plate 422 is fixedly connected to the compensation plate 4217 and is fixedly connected to the movable plate 4216. The compensation plate 4217 has a waist-shaped groove 4219, and the rotating rod 4218 is located in the waist-shaped groove 4219, so that when the rotating wheel 4214 rotates, the movable plate 4216 will only move along the line connecting the tassel-threading device 5 and the tassel-distributing mechanism; when the transmission gear rotates, the rotating rod 4218 drives the compensation plate 4217 to reciprocate along the line connecting the tassel-threading device 5 and the tassel-distributing mechanism, so that the gripping component 423 can repeatedly grip the tassels and hang them on the tassel-threading device 5. The gear transmission assembly employs a two-stage transmission to achieve a transmission ratio of 25-35 between the transmission gear and the input end of the gear transmission assembly. This ensures that for every rotation of the turntable 51, the transmission gear rotates one revolution. The diagram shows only a single gear in the gear transmission assembly; in reality, multiple gears mesh together.

[0060] More specifically, the gripping component 423 includes a moving block 4231 and a clamping block 4233. The moving block 4231 is hinged to the moving plate 4216. A sliding groove 4232 is provided on the moving block 4231. Two clamping blocks 4233 are provided, and both slide within the sliding groove 4232. A compression spring 425 is connected between the two clamping blocks 4233 to apply a spring force for the two clamping blocks 4233 to move in opposite directions. Each clamping block 4233 is connected to a clamping hook 4234, which includes an integrally formed rod portion 4235 and a hook portion 4236. The rod portion 4235 is fixedly connected to the clamping block 4233. A hook groove 4133 is provided along its own length direction on the tassel conveyor belt 413. The hook groove 4133 is annular and its depth is greater than the depth of the conveyor groove 4132. The hook groove 4133 is suitable for the insertion of the hook portion 4236. When the hook 4236 extends into the groove, it is lower than the bottom of the conveyor trough 4132. At this time, as the tassel conveyor belt 413 moves, the tassel suspension belt 52 in one of the conveyor troughs 4132 is transferred to the hook 4236. Then, the moving plate 4216 moves towards the turntable 51 to hook the tassel suspension belt 52 onto the hanging rod 511 of the turntable 51. The hook 4236 is preferably inserted into the groove above and to the side of the conveyor roller, where the tassel suspension belt 52 moves downwards while moving towards the turntable 51, facilitating automatic hooking onto the hook 4236.

[0061] Two guide rails 424 are also fixedly connected to the fixed plate 4215. Each guide rail 424 includes a first straight section 4241, an inclined section 4242, and a second straight section 4243 connected in sequence. The second straight section 4243 is located close to the tassel distribution mechanism 41, and the distance between the two first straight sections 4241 is greater than the distance between the two second straight sections 4243. Two clamping blocks 4233 are located between the two guide rails 424. When the moving block 4231 moves, the two clamping blocks 4233 abut against the two guide rails 424 under the action of the compression spring 425. When the two clamping blocks 4233 abut against the two first straight sections 4241, the distance between the two clamping hooks 4234 is relatively large, and the two clamping hooks 4234 are suitable for hanging the tassel suspension belt 52 on the hanging rod 511 of the turntable 51. When the clamping block 4233 abuts against the second straight section 4243, the distance between the two clamping hooks 4234 is small, and the clamping hooks 4234 are suitable for extending into the hook groove 4133.

[0062] During operation, the tassel suspension belt 52 is suspended from the tassel tube 411 and gradually slides down along the tassel tube 411 into the conveyor groove 4132. Subsequently, the tassel conveyor belt 413 conveys the tassel suspension belt 52. At this time, the turntable 51 rotates synchronously. While the turntable 51 rotates, the gear transmission assembly drives the transmission gear to rotate, which drives the rotating wheel 4214 to rotate. The rotating rod 4218 drives the moving plate 4216 to move towards the tassel distribution mechanism, so that the hook 4236 extends into the hook groove. At 4133, the tassel conveyor belt 413 just causes the tassel suspension belt 52 to fall onto the hook 4236. Then, the hook 4236 moves the tassel suspension belt 52 towards the turntable 51. The turntable 51 is about to rotate to its final position, so the hanging rod 511 is also about to reach its final position. Since the distance the two hooks 4236 spread apart the tassel suspension belt 52 is greater than the distance between the two hanging rods 511, the two hooks 4236 can pull the spread tassel suspension belt 52 onto the two hanging rods 511. Subsequently, the movable end of the fifth telescopic member 4121 retracts, the moving plate 4216 lowers as a whole, the hook 4236 decreases in height, and moves below the turntable 51 to avoid interference with the turntable 51. This also avoids interference with the hung tassels when the hook 4236 moves towards the tassel distribution mechanism 41 again. As the moving plate 4216 moves toward the tassel distribution mechanism, after the clamping hook 4234 passes over the tassel 53, the movable end of the fifth telescopic member 4121 extends again, causing the clamping hook 4234 to lift up, making it easier for the hook part 4236 to extend into the hook groove 4133.

[0063] Reference Figures 12 to 14 The insert device 7 can employ a robot assembly system for bookmark production lines, as disclosed in Chinese patent application CN116331619A. The unloading device 9 includes a spider-hand robotic arm 91 and unloading conveyor components 92. Multiple sets of unloading conveyor components 92 are provided, and the spider-hand robotic arm 91 transfers the bookmark sleeves on the second conveyor device 2 to different unloading conveyor components 92.

[0064] A production process, based on the aforementioned automated bookmark production line, includes the following steps:

[0065] S1. AGV robot 83 transfers tray 81 to loading device 8. Loading device 8 transfers bookmark board 93 to first conveying device 1. Then AGV robot 83 transfers tray 81 to boxing device 6. Boxing device 6's boxing robot arm 61 transfers bookmark sleeve and bookmark box 94 to box insertion device 7.

[0066] S2. The first laser engraving machine 31 engraves a pattern and identification code on the bookmark board 93. The first barcode scanner 32 scans the bookmark board 93 with the engraved pattern and identification code. The first camera 37 simultaneously captures the pattern and identification code. Based on the information captured by the first barcode scanner 32 and the first camera 37, it is determined whether the bookmark board 93 is a good product. If the bookmark board 93 is a defective product, the first rejection mechanism 35 rejects the defective bookmark board 93. If the bookmark board 93 is a good product, the good bookmark board 93 is continued to be conveyed by the first conveying device 1.

[0067] S3. The boxing robot arm 61 transfers the bookmark board 93 from the first conveying device 1 to the tassel-threading device 5, and the tassel-threading device 5 threads the tassel onto the bookmark board 93.

[0068] S4. The robotic arm 61 places the bookmark board 93 with tassels into the bookmark box 94. (Refer to Figure 14 to...) Figure 17 During the boxing process, the boxing robot arm 61 uses the transfer gripper 62 to pick up the bookmark board 93 with tassels, moves the bookmark board 93 above the bookmark box 94, and lowers it so that the tassels 53 first contact the bottom surface inside the bookmark box 94. Then, the bookmark board 93 moves horizontally and downwards, causing the tassels 53 to gradually tilt and finally lie flat inside the bookmark box 94. The bookmark board 93 is then moved horizontally again until it is in its horizontal position, and then moved downwards until it falls into the bookmark box 94. At this point, the bookmark board 93 is placed in the preset position, completing the boxing of the bookmark board 93. Through the above steps, the tassels 53 are prevented from protruding outside the bookmark box 94. The bookmark box 94 in the picture is only for illustration purposes. In reality, the bookmark box 94 has an empty slot inside. After the bookmark board 93 and the tassel are put in, the top surface of the bookmark board 93 will not exceed the top surface of the bookmark box 94.

[0069] S5. The inserting device 7 inserts the bookmark box 94 containing the bookmark board 93 into the bookmark sleeve, and transfers the bookmark sleeve containing the bookmark box 94 to the second conveying device 2. The second laser engraving machine 33 engraves patterns and identification codes on the bookmark sleeve. The second barcode scanner 34 and the second camera 38 scan and photograph the bookmark sleeve with the engraved identification code. The second rejection mechanism 36 rejects the bookmark sleeves that are defective, and the good bookmark sleeves are continued to be conveyed by the first conveying device 1.

[0070] S6. The unloading device 9 sorts and unloads the bookmark sleeves containing the bookmark boxes 94, thus completing the production of the bookmarks.

[0071] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
