[0043] The present invention is a device for intelligent sorting and feeding during the rapid slitting of agent strips while ensuring high precision and quality of the agent strips.
[0044] The present invention can be widely applied to virus reagent cards, pregnancy test cards of various sizes, reagent cards for various human health detections, as well as the rapid and highly precise automatic slitting and sorting of medical, food, pharmaceutical, and electronic products.
[0045] The following further describes the present invention in detail with reference to the accompanying drawings and embodiments.
[0046] As Figure 1 shown, the high-speed precision slitting and paper cutting machine of the present invention is provided with a machine case 1, a workbench is arranged on the upper part of the machine case 1, the full-automatic execution mechanism 5 of the present invention is all arranged on the workbench, an electric control box 2 for controlling the full-automatic execution mechanism 5 is further arranged inside the machine case 1, and a protective cover 4 is arranged around the workbench.
[0047] Preferably, the chassis 1 of this example is formed by welding 3-mm sheet metal, ensuring the strength, stability, and aesthetics of the equipment. The electric control box 2 is placed inside the chassis, saving space and reducing costs. A touch screen 3 is also provided on the protective cover 4, and operation buttons are provided below the touch screen. In this example, placing the touch screen 3 on the protective cover 4 facilitates the operator to maintain and debug the equipment. The operating height of the touch screen is 1.4M, which is more comfortable for the operator. The protective cover 4 is made of a combination of sheet metal and transparent plexiglass, allowing the operator to more intuitively see the operation of the equipment from the outside. Indicator lights are also provided above the protective cover 4, and rollers are provided at the bottom of the chassis 1 to facilitate the movement of the paper cutting machine of the present invention. The strip intelligent storage and sorting mechanism 13 of the full-automatic actuator 5 of this example is arranged at the outermost end of the workbench and outside the protective cover 4, facilitating the docking and material taking with the equipment of the next process.
[0048] As Figure 2 shown, the full-automatic actuator 5 of this example includes a sheet board blanking mechanism 6, a sheet board feeding mechanism 7, a strip cutting mechanism 8, a strip displacement mechanism 9, a strip detection mechanism 10, a strip waste rejection mechanism 11, a strip picking and placing mechanism 12, and a strip intelligent storage and sorting mechanism 13, which are arranged in sequence according to the paper cutting process. Among them,
[0049] the sheet board blanking mechanism 6 includes a loading board arranged on the workbench, and the sheet board blanking mechanism is used to convey the sheet board to be cut into strips onto the loading board on the workbench.
[0050] The sheet board feeding mechanism 7 is used to fix and convey the sheet board to the strip cutting mechanism 8.
[0051] The strip cutting mechanism 8 is arranged at the output end of the sheet board feeding mechanism 7 and is used to cooperate with the sheet board feeding mechanism 7 to cut the sheet board into strips.
[0052] The strip displacement mechanism 9 is linked with the strip cutting mechanism 8 and is used to transfer the strips cut by the strip cutting mechanism 8 one by one.
[0053] The strip detection mechanism 10 is arranged above the strip displacement mechanism through a fixed column and is used to detect the strips transferred by the strip displacement mechanism 9.
[0054] The strip waste rejection mechanism 11 is arranged at the other end of the strip displacement mechanism relative to the strip cutting structure and is used to sort the strips detected by the strip detection mechanism.
[0055] The strip picking and placing mechanism 12 is used to grab the strips transferred by the strip displacement mechanism onto the strip intelligent storage and sorting mechanism.
[0056] The intelligent storage and sorting mechanism of the agent strip is provided with a plurality of agent strip storage slots arranged in an array, and the intelligent storage and sorting mechanism of the agent strip stores and sorts the agent strips in the agent strip storage slots.
[0057] As Figure 3 shown, the agent plate blanking mechanism 6 of this example includes a panel 601 fixed above the chassis 1. The material receiving plate 603 is supported and fixed by 4 support columns 602. Two connecting plates 605 are fixed by two front and rear support blocks 604. In this example, a plurality of notches are arranged side by side at the top of the support block 604. The width of the two connecting plates 605 can be adjusted by using the fixing method of the notches. Of course, in this example, a guide rail slider structure can also be used to adjust the width of the two connecting plates 605, and the slider is driven by a motor. As another embodiment of the present invention, in this example, the width adjustment structure can also be arranged on the material receiving plate 603, and the support block 604 is columnar, with a connecting plate fixed at the top. By adjusting the distance between the two support blocks 604, the distance between the connecting plates 605 on the support blocks 604 can be indirectly adjusted.
[0058] As the third embodiment of the present invention, the number of the connecting plates 605 in this example is 1. An agent plate stacking position is arranged on the connecting plate 605, and a width adjustment structure for adjusting the width of the agent plate stacking position is arranged on the periphery of the agent plate stacking position.
[0059] The periphery of the agent plate stacking position in this example is defined by the limit posts 607. In this example, 8 adjusting blocks 606 are symmetrically fixed on the two connecting plates 605 respectively, and the limit posts 607 are fixed on the adjusting blocks 606. The product agent plate 608 is placed in the middle of the limit posts. Different widths of products can be placed according to needs. Longitudinally arranged notches are also arranged on the connecting plates 605. The adjusting blocks 606 are fixed on the notches. The adjusting blocks 606 are used to adjust to the corresponding length and width. A feeding wheel 609 is also arranged on the adjusting blocks 606 to support the product agent plate 608.
[0060] The driving device in this example is vertically driven to pull the agent plate 608 down to the material receiving plate 603 below the agent plate stacking position. It is vertically arranged, with a short movement stroke and a smaller space area. Moreover, the driving device is arranged below the agent plate stacking position, which is not easy to interfere with manual work and has higher safety performance.
[0061] In this example, the driving device is a downward pulling cylinder 611. The downward pulling cylinder 611 is fixed on the cylinder fixing plate 610. The cylinder fixing plate 610 is locked to the bottom surface of the 601 panel. The cylinder connecting plate 612 is fixed on the moving block of the downward pulling cylinder 611. The movement of the cylinder drives the cylinder connecting plate 612 to move up and down. The suction cup connecting shaft 613 is fixed on the cylinder connecting plate 612. A vacuum suction cup 614 is installed on the suction cup connecting shaft 613 (in this example, in order to be able to see the vacuum suction cup 614, the agent plate 608 is placed obliquely). The vacuum suction cup 614 adsorbs to the bottommost agent plate 608 on the agent plate stacking position. The downward pulling cylinder 611 moves downward, and then the feeding mechanism pushes the feed. The downward pulling cylinder 611 continues to move upward, adsorbs to the bottommost agent plate 608 on the agent plate stacking position again, and then moves downward to suck down the agent plate 608 and place it on the 603 receiving plate. This is repeated to complete the blanking. When pulling down, the dialing wheel 609 can prevent the second agent plate from being pulled down and plays a role in separating the materials.
[0062] The agent plate blanking mechanism 6 of the present invention has the following advantages:
[0063] 1. The overall structure design adopts the method of adding materials from the top. When the agent plates are reduced, there is no need to stop the machine. When the equipment is in operation, agent plate materials can be added from the top.
[0064] 2. The storage of the agent plates is limited by columns on the side. The structure is simple, the cost is low, and a larger space is opened up, which is convenient for manual replenishment of agent plate materials.
[0065] 3. The limiting width of the limiting columns for storing the agent plates can be adjusted according to the product, and different sizes of agent plates can be used commonly, and the universality of the structure is relatively strong.
[0066] 4. Vertical blanking occupies less space, does not interfere with manual work, and has higher safety.
[0067] As Figure 4 and Figure 5 shown, the agent plate feeding mechanism 7 in this example includes a combined agent plate cylinder 701 arranged below the receiving plate, and an agent plate pushing plate 703 arranged on the receiving plate 603 and driven by the combined agent plate cylinder 701. It also includes an agent plate limiting plate 705 arranged on the receiving plate 603, parallel to the agent plate pushing plate 703, and in the pushing direction of the agent plate pushing plate 703. A fixing structure for fixing the agent plate 608 is arranged between the agent plate pushing plate 703 and the agent plate limiting plate 705. It also includes a horizontal moving mechanism, and the horizontal moving mechanism is connected to the fixing structure and drives the fixing structure and the fixed agent plate to move on the receiving plate in the direction of the strip cutting mechanism. The fixing structure in this example can be clamping fingers or other structures such as pressing plates. The horizontal moving mechanism in this example is a linear moving module, such as a linear motor, etc.
[0068] Specifically, the agent plate pusher plate 703 in this example is fixed on the cylinder connection block 702 and guided by the linear guide 706. When the agent plate feeding mechanism 6 feeds the material, the combined agent plate cylinder 701 is in the open state. After the feeding is completed, the combined agent plate cylinder 701 closes and drives the agent plate pusher plate 703 to move, pushing the agent plate 608 flat to the agent plate limit plate 705 and stopping. The horizontal movement mechanism is a standard slide table module 707, which is guided by a lead screw and a linear guide and driven by a servo motor 708. The fixed block of the slide table 709 is connected to the slide table module 707 and transferred through the slide table connection block 710. One end of the connecting rod 711 is fixed on the slide table connection block 710.
[0069] The material receiving plate 603 is also provided with a guide rail for the movement of the agent plate fixing structure. The agent plate fixing structure includes agent plate clamping fingers 713 and an agent plate clamping cylinder 712 for driving the agent plate clamping fingers 713 to clamp and release the agent plate. It also includes a slider that cooperates with the guide rail, and the agent plate clamping cylinder 712 is arranged on the slider.
[0070] The slider or the agent plate clamping cylinder 712 is fixedly connected to the connecting rod 711. The whole agent plate fixing structure moves together with the connecting rod 711. The agent plate clamping fingers 713 are installed on the agent plate clamping cylinder 712. After the agent plate clamping fingers 713 clamp the agent plate, the slide table module 707 moves, pushing the agent plate 608 forward and providing it to the strip cutting mechanism 8. The strip cutting mechanism operates once every 3 mm of pushing. Until a whole agent plate is cut, the pushing distance each time can be set according to the width requirement of the product. The slide table module 707 drives the agent plate clamping fingers 713 to return to the origin, and the agent plate clamping fingers 713 release, dropping the waste on the agent plate clamping fingers 713 into the waste box 714 below the material receiving plate 603.
[0071] In this example, the slide table module is arranged on one side of the pusher plate of the agent plate position adjusting structure, which is beneficial to shortening the length of the whole equipment and making its structure more compact. Of course, if the length problem is not considered, then the connecting rod is not needed and direct driving at the end can be adopted.
[0072] In this example, the agent plate feeding mechanism 7 feeds automatically, and the servo mechanism is adopted for feeding the cutting edge, with fast speed and high precision. The cutting width of the agent strip can be cut into different width sizes according to the product requirements, and only the distance of the servo feeding needs to be modified, so the versatility is relatively strong.
[0073] Such as Figure 6 and Figure 7As shown, the strip cutting mechanism 8 in this example includes a main fixed plate 801 disposed on the workbench, a driving mechanism disposed below the main fixed plate 801, a lower cutting knife 817 disposed above the main fixed plate 801 through a lower cutting knife fixed plate 816, an upper cutting knife 820 disposed corresponding to the lower cutting knife 817, the upper cutting knife 820 is disposed on an upper cutting knife connecting plate 819, the upper cutting knife connecting plate 819 is disposed on an upper cutting knife fixed plate 818, a limiting block is provided on the upper cutting knife fixed plate 818, and the upper cutting knife connecting plate 819 can move in the vertical direction driven by the driving mechanism.
[0074] The driving mechanism in this example includes a servo motor 803, a cutting knife cam 808 that rotates in cooperation with the servo motor 803, a swing rod 813, and a connecting rod 814. A swing rod fixing block 812 is provided on the main fixed plate 801. One end of the swing rod 813 is movably connected to the swing rod fixing block 812. The other end of the swing rod 813 is hinged to one end of the connecting rod 814. The other end of the connecting rod 814 is fixedly connected to the upper cutting knife connecting plate 819. The swing rod 813 cooperates with the cutting knife cam 808 to drive the connecting rod 814 to move vertically.
[0075] Specifically, the main fixed plate 801 of this example is fixed on the panel 601, the reducer 802 fixed plate is fixed under the panel 601, the servo motor 803 and the reducer 804 are predetermined on the reducer fixed plate 802, and the transmission shaft 810 is driven to rotate through the coupling 805. The transmission shaft fixed plate 806 is fixed on the bottom surface of the main fixed plate 801, and the bearing 811 is installed to limit the transmission shaft 806. The swing arm fixed block 812 is fixed on the bottom surface of the main fixed plate 801, and the swing arm The fixing block 812 is connected to the swing rod 813, and the follower bearing 809 is installed in the swing rod 813. The cutter cam 808 drives the follower bearing 809 to make the swing rod 813 swing up and down, driving the connecting rod 814 to move up and down. The connecting rod limit block 815 is fixed to the lower cutter fixing plate 816 to limit the connecting rod 814. The connecting rod 814 and the swing rod 813 are connected by a swing rod connecting shaft 825 to achieve the effect of transmission and floating. The lower cutter 817 and the upper cutter fixing plate 818 are simultaneously The upper cutter connecting plate 819 is fixed on the lower cutter fixing plate 816, and the upper cutter connecting plate 819 is connected to the left cutter movement limit block 821 through the fixed shaft 822. The left cutter movement limit block 821 limits the left side of the upper cutter connecting plate 819. The cutter movement connecting shaft 824 connects the right side of the upper cutter connecting plate 819 with the connecting rod 814, so that the upper cutter 820 moves downward, and the lower cutter 817 and the upper cutter 820 are combined to cut the agent plate. The cutter in this example is made of tungsten steel with higher hardness. The service life is longer, and the cut dosage strips are more beautiful and stable. The right cutter movement limit block 823 limits the upper cutter to protect the cutter from being damaged. The dosage plate guide block 826 is provided with a guide hole for the dosage plate to pass through and limit, to guide the dosage plate, and the dosage plate can be transported from the guide hole on the back of the upper cutter fixing plate to the upper surface of the lower cutter to complete the cutting, thereby ensuring the accuracy of dosage strip cutting. The dosage plate guide block 826 can be adjusted to a suitable position according to the width of the dosage plate, and has stronger versatility.
[0076] As another embodiment of the present invention, a swing arm can be directly arranged on the cutter cam 808 or the transmission shaft, and one end of the swing arm is hinged to the connecting rod, thereby driving the connecting rod to swing up and down, thereby driving the upper cutter to press down to complete the cutting. Of course, this example can also use a cylinder + guide shaft to achieve the vertical movement of the upper cutter. This example is to achieve that the same driving mechanism drives the cutter mechanism and the dosage strip displacement mechanism at the same time, so that the two are linked. Therefore, the first embodiment is preferred.
[0077] The strip cutting mechanism 8 of the present invention has the following advantages:
[0078] 1. The cutter is made of tungsten steel and has a long service life;
[0079] 2. The cutter is powered by a servo motor and a cam, making cutting smoother and more stable.

A sliding plate 904 is provided on the two second linear guides 903 and can slide along the second linear guides 903. In this example, the sliding plate 904 is fixedly connected to the main fixing plate 801. It further includes a lifting structure provided on the displacement mechanism fixing plate 901, and a strip displacement block 907 provided above the lifting structure. The lifting structure and the strip displacement block together form a lifting clamping structure. A plurality of card slots for fixing the strip 910 are provided at the top of the strip displacement block 907. It also includes a side fixing block 909 provided on the sliding plate 904, a strip supporting block 917 and a supporting limit block 918 fixed to the top of the side fixing block 909. A strip conveying channel for allowing the strip 910 to move between the two is provided between the strip supporting block 917 and the supporting limit block 918. A limiting structure that is linked with the lifting structure and limits the strip in the strip conveying channel is further provided at the top of the supporting limit block 918. This example also includes a first driving structure for driving the horizontal movement of the displacement mechanism fixing plate and a second driving structure for driving the lifting structure. The first driving structure and the second driving structure of this example both use the servo motor 803 and the speed reducer 804 of the strip cutting mechanism 8 as the same power source, and both rotate together with the transmission shaft of the speed reducer 804.
[0081] Specifically, the lifting structure in this example includes a lifting guide plate 905, a lifting movable plate 906, and a lifting limit block 908. The lifting guide plate 905 is connected to the lifting limit block 908 and fixed on the displacement mechanism fixing plate 901 to guide and limit the lifting movable plate 906. Two strip displacement blocks 907 are fixed on the lifting movable plate 906. The displacement connecting plate 911 is fixed on the displacement mechanism fixing plate 901. The displacement cam 912 is fixed on the transmission shaft 810 and rotates with the transmission shaft 810. The displacement connecting plate 911 is moved through the displacement follower bearing 913. At the same time, the displacement mechanism fixing plate 901 is displaced by 15 mm, so that the strip 910 on the first material receiving block 902 is moved by 15 mm. The two ends of the strip 910 slide into the strip conveying channel. At the same time, the lifting cam 914 is fixed on the transmission shaft 810 and rotates. The lifting connecting plate 916 is driven to move upward through the lifting follower bearing 915. The lifting connecting plate 916 is connected to the lifting movable plate 906, so that the card slot at the top of the strip displacement block 907 catches the strip 910. Then, with the rotation of the transmission shaft 810, the displacement cam 912 drives the first material receiving block 902 back to its original position. In this example, the side fixing block 909 is fixed on the sliding plate 904. The pressing connection block 919 and the pressing lifting block 920 are connected to the lifting movable plate 906 and move up and down together. The pressing pin 921 is installed in the pressing connection block 919. The pressing pin 921 is sealed with the cover plate 922 and a spring is placed in the middle to press the strip 910 to prevent the strip 910 from running out of position during displacement. Repeating this process in sequence, the strip cutting mechanism 8 and the strip displacement mechanism 9 of the present invention are linked, and the strip 910 moves step by step towards the strip waste removal mechanism 11 side one by one.
[0082] The strip displacement mechanism 9 of this example uses the servo motor of the strip cutting mechanism 8 in cooperation with the displacement cam and the lifting cam as the power, and is equipped with a linear guide rail for displacement drive, with good stability, high speed, and high efficiency. In addition, a very small spring design is cleverly used to press the strip to prevent it from moving around.
[0083] Such as Figure 12As shown, the strip detection mechanism 10 of the present invention is a CCD vision detection mechanism. Specifically, in this example, the camera fixing base plate 1001 is fixed on the 601 panel. The camera fixing column 1002 is connected to the camera fixing base plate 1001. The camera fixing plate 1003 is fixed at the top of the fixing column 1002 and is perpendicularly arranged with the fixing column 1002. The camera 1004 is fixed at the end of the camera fixing plate 1003 through the camera adapter plate 1005. The camera 1004 takes pictures of the strip to detect the integrity of the product and whether it is qualified. If it is unqualified, it will be removed by the strip waste removal mechanism 11. The light source 1006 fixing plate is fixed on the camera fixing column 1002. The light source 1008 is fixed on the light source fixing plate 1006 through the light source adapter plate 1007. The light source 1008 illuminates the strip to ensure that the pictures taken by the camera are clearer and more stable. The recycling box 1009 below the strip waste removal mechanism 11 is used to collect defective products.
[0084] As Figure 13 and Figure 14 shown, the strip waste removal mechanism 11 of this example includes a linear guide 1101, a moving plate 1102, a second receiving block 1106, and a cylinder 1104 that drives the moving plate 1102 to move linearly along the linear guide. The second receiving block 1106 is arranged on the top of the moving plate 1102 and is located at the discharge end of the strip displacement mechanism 9. The strip waste removal mechanism 11 further includes a recycling box 1009 arranged below the moving plate for collecting non-conforming products. Of course, the second receiving block 1106 of this example can also be set as a separate transfer component, and the recycling box 1009 can also be set separately.
[0085] The linear guide 1101 of this example is fixed on the displacement mechanism fixing plate 901. The moving plate 1102 is fixed on the linear guide slider and slides. The cylinder 1104 is connected to the displacement mechanism fixing plate 901 through the cylinder fixing block 1103 and is connected to the moving plate 1102 through the floating joint 1105. The movement of the cylinder 1104 directly drives the moving plate 1102 to move back and forth, and then drives the second receiving block 1106 to move. If the product detected by the strip detection mechanism 10 is qualified, the second receiving block 1106 catches the strip and provides it for the strip picking and placing mechanism 12 to grab. If it is unqualified, the cylinder 1104 moves to remove the product, which falls into the recycling box 1009 for recycling.
[0086] As Figures 15 - 17As shown in the figure, the strip picking and placing mechanism 12 in this example includes a linear motion module 1202 disposed above the strip displacement mechanism 9 and the strip waste removal mechanism 11 and arranged along the strip conveying direction, and a servo motor 1203 for driving the linear motion module 1202. A vertical motion module is provided on the linear motion module 1202. A transfer block is connected to the drive shaft of the vertical motion module. A clamping member for clamping and picking up the strip is provided at the bottom of the transfer block.
[0087] The bottom plate 1201 of the storage mechanism in this example is fixedly connected to the 601 panel. The linear motion module 1202 in this example is a slide table module. The slide table module is a synchronous belt and linear guide structure and is driven by a servo motor 1203 to drive the slide table cylinder fixing plate 1207 to move. If the strip output direction in this example is not set in the same direction as the input direction of the strip intelligent storage and sorting mechanism 13, the linear motion module in this example can also be provided with an X-direction motion module and a Y-direction motion module that cooperate with each other to realize the translation of the clamping member in any direction on the plane.
[0088] The vertical motion module in this example is a cylinder vertical motion module. The module fixing plate 1204 fixes the slide table module and is connected to the fixed bottom plate 1206 through a 1205 reinforcing rib and is fixed on the bottom plate 1201 of the storage mechanism. The slide table cylinder 1208 is fixed on the slide table cylinder fixing plate 1207. The cylinder transfer block 1209 is fixed on the slide table cylinder moving block 1208 to move up and down. The finger cylinder 1211 is connected to the cylinder transfer block 1209 through a finger cylinder fixing block 1210. When the finger cylinder 1211 moves downward, the left finger 1212 and the right finger 1213 grab the strip. At the same time, the clamping and pressing block limits the strip to prevent the strip from tilting due to unbalanced forces on the two fingers, resulting in unfavorable clamping and causing the strip to fall. When the slide table cylinder 1208 moves upward, the slide table module sends the strip to the strip intelligent storage and sorting mechanism 13.
[0089] The strip picking and placing mechanism 12 of the present invention uses a servo module as the power for rapid movement, with high speed and high precision. The strip is grabbed by the cooperation of a slide table cylinder and a finger cylinder, which can accurately grab the strip, with a simple structure and low cost. The fingers are made of SUS304 stainless steel material to prevent product contamination after rusting, and the fingers are surface-treated with sprayed Teflon (polytetrafluoroethylene) to prevent sticking to the strip during picking and placing.
[0090] As Figure 18 and Figure 19As shown in the figure, the intelligent storage and sorting mechanism 13 of the agent strip in this example includes a belt conveyor line arranged above the workbench. The belt conveyor line is fixed on the bottom plate 1201 of the storage mechanism through the first belt line support plate 1301 and the second belt line support plate 1302 at the same time, and the plate connecting rod 1303 is used for reinforcement and stability in the middle. The belt line synchronous driving wheel 1304 is fixed on the synchronous wheel driving shaft 1312, and the belt line synchronous driven wheel 1305 is fixed on the synchronous wheel driven shaft 1313. Two customized synchronous belts 1307 are used for connecting and rotating. Along the width direction, a plurality of notches are evenly arranged on the upper surface of the synchronous belt 1307 in this example. The notches on the synchronous belt 1307 are used to place the agent strips, separate and store the agent strips, and prevent the glues of the agent strips from sticking to each other.
[0091] The synchronous belt limiting piece 1306 limits the synchronous belt 1307 to prevent deviation. The servo motor 1308 is fixed on the servo motor fixing plate 1309, and is connected to the first belt line support plate 1301 through the motor fixing connecting rod 1310 for fixation. A coupling 1311 is used to connect the servo motor 1308 and the synchronous wheel driving shaft 1312 in the middle to drive the synchronous wheel. The driving wheel bearing 1314 fixes and limits the synchronous wheel driving shaft 1312, and the driven wheel bearing 1315 fixes and limits the synchronous wheel driven shaft 1313 to make the synchronous wheel rotate more smoothly. The agent strip support plate 1322 holds the agent strip to prevent it from sagging in the middle. The support block 1316 of the support plate supports and fixes the agent strip support plate 1322. The first agent strip side limiting plate 1317 and the second agent strip side limiting plate 1318 are fixed between the first belt line support plate 1301 and the second belt line support plate 1302 to provide side limiting protection for the agent strip.
[0092] This example is also provided with an induction device. Specifically, the sensor 1321 is fixed on the second agent strip side limiting plate 1318 through the sensor fixing piece 1320 to detect the last agent strip and provide it for other equipment to grab. Every time an agent strip is taken away, the synchronous belt moves forward one step to supplement the agent strip at the end. At the same time, an agent strip position sensor 1319 is installed on the side of the second agent strip side limiting plate 1318, and an extremely small optical fiber head is used to detect the presence or absence of the agent strip. When it is detected that there is no agent strip in the notch, the agent strip picking and placing mechanism 12 supplements the vacant agent strip position on the synchronous belt until the position is filled, so as to achieve the intelligent storage and sorting of the agent strip.
[0093] The present invention uses the synchronous belt structure design to solve the problem of mutual adhesion of agent strips during sorting and storage; a very small optical fiber sensor is designed at the storage position to monitor the presence or absence of agent strips to achieve the purpose of intelligent storage; the synchronous belt is driven by a servo motor to make the synchronous belt perform jogging operation, with fast speed, high precision and good stability.
[0094] In summary, through the cooperation of various mechanisms and intelligent storage and sorting, the present invention perfectly solves the problem that the agent strips cannot be stored after cutting, and greatly improves the stability and working efficiency of the equipment.
[0095] The above-described specific embodiments are the preferred embodiments of the present invention, and do not limit the specific implementation scope of the present invention. The scope of the present invention includes but is not limited to this specific embodiment. All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
