Description

Technical Field

[0001] The present invention relates to the technical field of product scanning and classification, and in particular to a scanning, sorting and merging line mechanism. Background Art

[0002] The FQC (Final Quality Control) packaging process is the last quality inspection link before the product is shipped in the manufacturing process, which is used to ensure that the product meets the customer requirements and standards at the packaging stage. In the FQC packaging process, it is necessary to scan the product code, classify the qualified products and unqualified products according to the scanning and recognition results, and finally package the qualified products and unqualified products separately to meet the quality requirements for product factory shipment. At present, in the FQC packaging process of glass products in the industry, especially optical glass products, after the surface of the glass is covered with a film by a film laminator, the operator places the glass to be scanned one by one in the scanning area of a fixed scanning gun for scanning and recognition, and manually classifies and packs the products according to the scanning and recognition results fed back by the equipment. When using the above scanning and classification method, the production capacity of the film laminating process is 1600 PCS / H, and the production capacity of manual scanning and packing is 1000 PCS / H, resulting in a serious mismatch in the production capacity between the upstream and downstream processes, and thus causing incoherence between the processes. In this case, 1 operator is required for the film laminating process and 1 auxiliary worker for transporting products. In this way, a total of 4 people are required to complete the work during the day and night shifts; the scanning process is manual operation, and 1 manual scanning operator is required, and a total of 2 people are required to complete the operation during the day and night shifts. In this way, a large amount of manual labor is required to participate in the operation, resulting in low efficiency of the product scanning and classification operation and relatively high operation costs. In addition, after the qualified products and unqualified products are manually scanned and recognized, the operator manually classifies them. If the employee's attention is not concentrated, it is easy to cause classification errors, which in turn affects the quality control of the products leaving the factory. Summary of the Invention

[0032] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0033] Please refer to Figures 1-3 as well as Figure 11, the present invention discloses a scanning and sorting line mechanism with high operation efficiency, low operation cost and high scanning and sorting accuracy. The scanning and sorting line mechanism includes a scanning unit 1 and a sorting and merging line unit 2. The scanning unit 1 includes a positioning platform 100 for receiving products to be scanned, a sheet transferring structure 200 for moving the products at the output end of the laminating machine 3 to the positioning platform 100, and a scanning gun 300 for scanning and identifying the product labels on the positioning platform 100; the sorting and merging line unit 2 includes a qualified product transporting structure 400 and a non-qualified product transporting structure 500 which are arranged in parallel and opposite to each other, and a sheet picking structure 600 which is signal-connected to the scanning gun 300 and is used for grasping and placing the scanned products into the qualified product transporting structure 400 or the non-qualified product transporting structure 500.

[0034] For the above scanning and sorting line mechanism, by setting the scanning unit 1 and the sorting and merging line unit 2, the sheet transferring structure 200 of the scanning unit 1 automatically receives the product incoming materials from the output end of the laminating machine 3, places the products at the positioning platform 100, and the scanning gun 300 scans and identifies the products at the positioning platform 100. Subsequently, the sheet picking structure 600 of the sorting and merging line unit 2 places the products into the corresponding qualified product transporting structure 400 and non-qualified product transporting structure 500 according to the scanning and identifying results, realizing the classification of products, so as to package the classified products. This mechanism replaces the manual scanning, identifying and classifying method, reduces the number of operating personnel, lowers the labor input cost, and improves the operation efficiency; by signal-connecting the scanning gun 300 and the sheet picking structure 600 and automatically classifying the products according to the identifying results, it can avoid the classification error problems caused by employees' inattention when using manual scanning and classification, so as to improve the product quality control effect.

[0035] Please further combine Figures 1-5 and Figure 11, in this embodiment, the code scanning unit 1 further includes a code scanning workbench 700 disposed at the output end of the laminating machine 3. The code scanning workbench 700 is used to provide support for the positioning platform 100, the sheet transferring structure 200, and the code scanning gun 300, and provide a work place for code scanning of products (glass sheets). Specifically, the code scanning workbench 700 includes a bench profile 710 for enclosing a rectangular parallelepiped or cube receiving space, a top sealing plate 720 fixed to the top of the bench profile 710 to seal the top of the receiving space, a bottom sealing plate fixed to the bottom of the bench profile 710 to seal the bottom of the receiving space, and a plurality of side door panels 730 disposed on each side of the bench profile 710 to jointly enclose the receiving space with the top sealing plate 720 and the bottom sealing plate. The top sealing plate 720 and the bottom sealing plate are respectively connected to the bench profile 710 by screws or bolts, and can also be fixedly connected to the bench profile 710 by welding. At least one side door panel 730 is hinged to the bench profile 710, and the remaining side door panels 730 are connected to the bench profile 710 by screws or welding. A first controller for controlling the operation of each electrical component in the code scanning unit 1, a first power supply for supplying power to each electrical component in the code scanning unit 1, and other electrical components such as transformers are provided in the receiving space. In order to facilitate the maintenance of the electrical components in the receiving space, at least one side door panel 730 on one side of the bench profile 710 is of an openable and closable structure. For example, each side of the bench profile 710 includes two side door panels 730 arranged side by side and capable of closing one side of the bench profile 710 when closed. Among them, magnets are provided at adjacent positions on at least one side of the two side door panels 730. In this way, by attracting the two side door panels 730 with the magnets, while facilitating the opening of the side door panels 730, the side door panels 730 can be prevented from opening by themselves. Of course, the adjacent two side door panels 730 can also be fixed by a lock or other locking methods, or only one side door panel 730 is rotatably provided on each side of the bench profile 710, and the closing of the side door panel 730 is achieved by providing magnets or corresponding lock structures on the bench profile 710. In addition, heat dissipation holes are provided on at least one side door panel 730, and a heat dissipation fan is provided inside the bench profile 710 adjacent to the heat dissipation holes to cool the inside of the bench profile 710 and prevent the electrical components from being damaged due to overheating. An electrical switch panel 740 electrically connected to the first controller and the first power supply and a fan panel electrically connected to the heat dissipation fan are provided on the outer surface of one side door panel 730, so that the operator can operate the electrical switch panel 740 to control the operation of the code scanning unit 1, or operate the fan panel to control the heat dissipation fan to work for heat dissipation inside the receiving space. The first controller is electrically connected to the controller of the laminating machine 3 to change and control the corresponding electrical components of the code scanning unit 1 to act according to the working conditions of the laminating machine 3, so as to realize the code scanning and identification of products. In addition, an audible and visual alarm 750 electrically connected to the first controller is further provided on the top sealing plate 720 to prompt the staff when a device failure occurs.

[0036] The line dividing and paralleling unit 2 also includes a line dividing and paralleling workbench 800 located on the positioning platform 100 on a side away from the output end of the laminating machine 3. In this embodiment, the structure of the line dividing and paralleling workbench 800 is the same as that of the code scanning workbench 700. The difference between the two lies mainly in the different sizes and the second controller electrically connected to the electrical components of the line dividing and paralleling unit 2 and the code scanning gun 300, and the second power supply for powering the electrical components of the line dividing and paralleling unit 2 are arranged in the frame profile 710 of the line dividing and paralleling workbench 800. The specific structure of the line dividing and paralleling workbench 800 is not repeated here. Preferably, the first controller and the second controller are both PLC controllers.

[0037] In addition, in the present embodiment, the positioning platform 100, the sheet moving structure 200 and the barcode scanning gun 300 are arranged on the barcode scanning workbench 700, the qualified product material transport structure 400, the unqualified product material transport structure 500 and the sheet picking structure 600 are arranged on the dividing and paralleling workbench 800, and a casing 101 is provided above the barcode scanning workbench 700 and above the dividing and paralleling workbench 800. One of the casings 101 is used to cover the positioning platform 100, the sheet moving structure 200 and the barcode scanning gun 300, and only the side thereof close to the output end of the laminating machine 3 and the side close to the dividing and paralleling workbench 800 are opened to transport the products; the other casing 101 is used to cover the qualified product material transport structure 400, the unqualified product material transport structure 500 and the sheet picking structure 600, and only the side thereof close to the barcode scanning workbench 700 and the side close to the dividing and paralleling workbench 800 are opened to provide a product moving channel. In this way, the product barcode scanning and classification workplace is separated from the environment, thereby improving the safety of the operation. Of course, at least a portion of the side surface of the housing 101 is made of transparent material so that the operator can observe the operation of the code scanning and dividing and merging mechanism in real time. In addition, a PC electrically connected to the first controller and the second controller is also provided on the outside of the housing so that the operator can check the working status of the equipment at any time and adjust the working parameters of the equipment.

[0038] According to the layout of the factory building, the feeding direction of the laminating machine 3 can be the same as or perpendicular to the feeding direction of the code scanning and dividing and paralleling mechanism. Preferably, in this embodiment, the feeding direction of the laminating machine 3 is the same as the feeding direction of the code scanning and dividing and paralleling mechanism, and the feeding direction of the laminating machine 3, the length direction of the code scanning workbench 700, and the length direction of the dividing and paralleling workbench 800 are agreed to be the X-axis direction, the width direction of the code scanning workbench 700 and the width direction of the dividing and paralleling workbench 800 are agreed to be the Y-axis direction, the height direction of the code scanning workbench 700 and the height direction of the dividing and paralleling workbench 800 are agreed to be the Y-axis direction or the vertical direction, and the plane surrounded by the X-axis and the Y-axis is a horizontal plane. In other embodiments, this explanation can also be referred to.

[0039] Please combine Figures 1-3 as well as Figures 6-7, the positioning platform 100 includes a fixing plate 110 disposed on the upper surface of the code scanning workbench 700, a bearing plate 120 erected on the fixing plate 110 and fixedly connected to the fixing plate 110, a plurality of X-axis fixing pins 121 located on one side of the bearing plate 120 and arranged along the feeding direction (X-axis direction) of the laminating machine 3, a Y-axis positioning column 122 located on the side of the bearing plate 120 opposite to the X-axis fixing pins 121 and slidably connected to the fixing plate 110 to approach or move away from the bearing plate 120, and X-axis positioning columns 123 arranged on the front and rear sides of the bearing plate 120 along the feeding direction of the laminating machine 3 and slidably connected to the fixing plate 110 to approach or move away from the bearing plate 120. The X-axis fixing pins 121 are fixedly connected to the fixing plate 110. An air suction groove 124 communicating with an external vacuum device is formed on the upper surface of the bearing plate 120 so that an adsorption surface is formed on the upper surface of the bearing plate 120. The top heights of the X-axis fixing pins 121, the Y-axis positioning column 122, and the X-axis positioning columns 123 are all higher than the height of the adsorption surface. The bearing plate 120, the X-axis fixing pins 121, the Y-axis positioning column 122, and the X-axis positioning columns 123 together enclose a product positioning area. In this embodiment, the Y-axis positioning column 122 can move along the Y-axis direction, and the X-axis positioning column 123 can move along the X-axis direction. The Y-axis positioning column 122 and the X-axis positioning columns 123 together form a jaw structure of the positioning platform 100. During the movement of the Y-axis positioning column 122 and the X-axis positioning columns 123, by controlling the movement amounts of the two, the product in the product positioning area can be pushed to a preset area, so as to realize the alignment calibration and positioning of the product entering the product positioning area, so that the product can be scanned at a specific position, preventing the problem of scanning failure caused by the barcode scanner 300 being unable to align with the product label. The bearing plate 120 is actually a vacuum adsorption plate, which can be an aluminum plate, an aluminum alloy plate, or a stainless steel plate, and is used to limit the product in the vertical direction by means of vacuum adsorption to prevent the product from moving up and down.

[0040] Further, in this embodiment, two carrier plates 120 are arranged side by side above the fixing plate 110. Independent Y-axis positioning posts 122 are provided on the same side of the two carrier plates 120. A plurality of Y-axis fixing pins 125 arranged along the Y-axis direction are further provided between the two carrier plates 120. In this way, each carrier plate 120 positions the product on the carrier plate 120 together with the X-axis fixing pin 121, the Y-axis positioning post 122, the Y-axis fixing pin 125, and the X-axis positioning post 123 on one side thereof. That is to say, the positioning platform 100 can load two products side by side at one time. The X-axis fixing pin 121 and the Y-axis fixing pin 125 are both installed on the fixing plate 110 through corresponding brackets. The fixing plate 110 is a rectangular plate, and a column 126 is fixed at each of the four corner portions thereof. The bracket of the X-axis fixing pin 121 is fixedly connected to two columns 126. A support plate 127 is fixed to the top of each of the other two columns 126. The support plate 127 is fixedly connected to the adjacent carrier plate 120. At the same time, the carrier plate 120 is also fixedly connected to the brackets of the X-axis fixing pin 121 and the Y-axis fixing pin 125 to realize the erection of the carrier plate 120 on the fixing plate 110.

[0041] In one embodiment, the positioning platform 100 further includes a first Y-axis linear module 130 fixed to the upper surface of the code scanning workbench 700, a module support plate 150 fixedly connected to the movable part 140 of the first Y-axis linear module and slidable along the width direction of the code scanning workbench 700, a Y-axis guide rail 160 and a first X-axis guide rail 170 located below the bearing plate 120 and mounted on the fixed plate 110, a Y-axis driving member (not shown in the figure) for driving the Y-axis positioning post 122 to slide on the Y-axis guide rail 160, a first X-axis driving member (not shown in the figure) for driving the X-axis positioning post 123 to slide on the first X-axis guide rail 170, and a first photoelectric sensor (not shown in the figure) mounted on the bearing plate 120 or the fixed plate 110 and electrically connected to the Y-axis driving member and the first X-axis driving member. The detection end of the first photoelectric sensor faces the product positioning area, and the fixed plate 110 is fixedly connected to the upper surface of the module support plate 150. In this embodiment, the first Y-axis linear module 130 is fixed to the upper surface of the code scanning workbench 700 through a straight rod tapered positioning pin 180. By providing the first Y-axis linear module 130, the position of the product on the positioning platform 100 in the Y-axis direction can be adjusted so that the product can be aligned with the code scanning gun 300. The Y-axis driving member may include a lead screw fixed to the Y-axis guide rail 160, a nut threadedly sleeved on the lead screw and slidably engaged with the Y-axis guide rail 160 through a guide rod, and a motor for driving the lead screw to rotate. The Y-axis positioning post 122 is fixed to the nut; or the Y-axis guide rail 160 and the Y-axis driving member together form a linear module, and the Y-axis positioning post 122 is fixed to the movable part of the linear module to drive the Y-axis positioning post 122. Correspondingly, the first X-axis driving member is the same as the Y-axis driving member and will not be elaborated here. The first photoelectric sensor, the Y-axis driving member, and the first X-axis driving member are all electrically connected to the first controller. By providing the first photoelectric sensor, when it detects that there is a product in the product positioning area, the first photoelectric sensor sends an electrical signal to the first controller so that the first controller controls the Y-axis driving member and the first X-axis driving member to work to adjust the positions of the Y-axis positioning post 122 and the X-axis positioning post 123, realizing the alignment and calibration positioning of the product.

[0042] In addition, in order to expand the applicable scenarios of the positioning platform 100, a first avoidance groove 128 corresponding to the Y-axis positioning post 122 is formed on the side of the bearing plate 120 adjacent to the Y-axis positioning post 122, and a second avoidance groove 129 corresponding to the X-axis positioning post 123 is formed on the side of the bearing plate 120 adjacent to the X-axis positioning post 123. In this way, while ensuring reliable product positioning, products with a lower surface size larger than the upper surface size of the bearing plate 120 or products with a lower surface size smaller than the upper surface size of the bearing plate 120 can be placed in the product positioning area, so as to expand the size range of products that the positioning platform 100 can carry, and further expand the applicable scenarios of the positioning platform 100.

[0043] Please combineFigures 1-3 and Figure 8 , the wafer transfer structure 200 includes a wafer transfer bracket 210 located beside the positioning platform 100 and fixed on the code scanning workbench 700, a second X-axis guide rail 220 fixed on the wafer transfer bracket 210, a wafer transfer mounting frame 230 slidably arranged on the second X-axis guide rail 220, a second X-axis driving member 240 fixed on the wafer transfer bracket 210 and used for driving the wafer transfer mounting frame 230 to move along the length direction of the code scanning workbench 700, a first Z-axis cylinder 250 fixed on the wafer transfer mounting frame 230, a first suction cup mounting frame located below the first Z-axis cylinder 250 and fixedly connected to the piston rod of the first Z-axis cylinder 250, and at least one first suction cup 260 fixed on the first suction cup mounting frame and communicated with an external vacuum device. The second X-axis guide rail 220 extends along the X-axis direction. The second X-axis driving member 240 may include a lead screw fixed on the second X-axis guide rail 220, a nut threadedly sleeved on the lead screw and slidably matched with the second X-axis guide rail 220 through a guide rod, and a motor for driving the lead screw to rotate, and the wafer transfer mounting frame 230 is fixed on the nut; or the second X-axis guide rail 220 and the second X-axis driving member 240 together form a linear module, and the wafer transfer mounting frame 230 is fixed on the movable part of the linear module to realize the driving of the wafer transfer mounting frame 230.

[0044] During the process of wafer transfer and clamping, first, the movable part 140 of the first Y-axis linear module drives the module support plate 150 and the other components on the module support plate 150 to move until the carrier plate 120 moves below the wafer transfer bracket 210. Subsequently, the second X-axis drive 240 drives the wafer transfer mounting bracket 230 to move along the X-axis direction to the output end of the laminating machine 3. The first Z-axis cylinder 250 drives the first suction cup mounting bracket to descend, so that the first suction cup 260 contacts the product at the output end of the laminating machine 3. Subsequently, the first suction cup 260 is connected to an external vacuum device, causing a negative pressure to be generated at the first suction cup 260 to adsorb the product. After the first suction cup 260 adsorbs the product, the first Z-axis cylinder 250 drives the first suction cup mounting bracket and the first suction cup 260 to lift, taking the product away from the output end of the laminating machine 3. The second X-axis drive 240 drives the wafer transfer mounting bracket 230 to move along the X-axis direction above the carrier plate 120. The first Z-axis cylinder 250 drives the first suction cup mounting bracket and the first suction cup 260 to descend again, placing the product on the upper surface of the carrier plate 120. The first suction cup 260 is immediately disconnected from the external vacuum device, and then the first Z-axis cylinder 250 controls the first suction cup mounting bracket and the first suction cup 260 to lift. At this time, the first photoelectric sensor detects that there is a product in the product positioning area and sends an electrical signal to the first controller, so that the first controller controls the Y-axis drive and the first X-axis drive to work to adjust the positions of the Y-axis positioning post 122 and the X-axis positioning post 123, making the Y-axis positioning post 122 and the X-axis positioning post 123 aligned, calibrated and clamping the product. At the same time, the air suction groove 124 of the carrier plate 120 is communicated with the external vacuum device to generate a negative pressure at the adsorption surface to adsorb the product.

[0045] In addition, a CCD camera electrically connected to the first controller can be provided on the wafer transfer bracket 210. When the first suction cup 260 picks up the product, the second X-axis drive 240 drives the first suction cup 260 to drive the product to move to the CCD camera. The CCD camera collects the product image information and sends it to the first controller. The first controller judges the product position and further controls the first Y-axis linear module 130 to work to adjust the position of the positioning platform 100 along the Y-axis direction so that the product can be accurately placed into the positioning platform 100.

[0046] Please combine Figures 1-3 and Figures 9-10, the code scanning unit 1 further includes a code scanning driving structure 310 located on the opposite side of the positioning platform 100 from the wafer transfer structure 200. It can be understood that in this embodiment, the laminating machine 3 is located at the rear side of the positioning platform 100, the splitting and merging line workbench 800 is located at the front side of the positioning platform 100, and the code scanning driving structure 310 and the wafer transfer structure 200 are located on the left and right sides of the positioning platform 100. The code scanning driving structure 310 includes a code scanning bracket 311 fixed on the code scanning workbench 700, a second Y-axis linear module 312 fixed on the code scanning bracket 311, an X-axis positioning bracket 313 fixedly connected to the movable part of the second Y-axis linear module 312 and slidable along the width direction of the code scanning workbench 700, a first X-axis linear module 314 fixed on the X-axis positioning bracket 313, a Z-axis positioning bracket 315 fixedly connected to the movable part of the first X-axis linear module 314 and slidable along the length direction of the code scanning workbench 700, and a second Z-axis cylinder 316 fixed on the Z-axis positioning bracket 315. The code scanner 300 is located below the second Z-axis cylinder 316 and fixedly connected to the piston rod of the second Z-axis cylinder 316, and the code scanning end of the code scanner 300 faces the product positioning area. In this embodiment, the second Y-axis linear module 312 is used to drive the code scanner 300 to move along the Y-axis direction, the first X-axis linear module 314 is used to drive the code scanner 300 to move along the X-axis direction, and the second Z-axis cylinder 316 is used to drive the code scanner 300 to move along the Z-axis direction. In this way, through the code scanning driving structure 310, the position of the code scanner 300 above the positioning platform 100 can be adjusted in three-dimensional space, so that the code scanning end of the code scanner 300 can be aligned with the product on the carrier plate 120 to accurately obtain the label information on the product. In addition, in this embodiment, the reason for setting both the code scanner 300 and the positioning platform 100 to be movable along the Y-axis direction is to avoid interference when the code scanning driving structure 310 and the wafer transfer structure 200 are arranged, to increase the distance between the two as much as possible, and to make the product as far away from the wafer transfer structure 200 as possible during code scanning, so as to avoid the wafer transfer structure 200 blocking the product, which may cause the problem that the code scanner 300 cannot normally scan the product label.

[0047] During the code scanning operation, the first controller receives the signal sent by the CCD camera and controls the second Y-axis linear module 312, the first X-axis linear module 314, and the second Z-axis cylinder 316 to work, adjusting the position of the code scanner 300 so that the code scanning end of the code scanner 300 is aligned with the product on the carrier plate 120. Subsequently, the code scanner 300 receives the signal sent by the first controller and scans the label on the product, and sends the collected label information to the first controller.

[0048] In order to improve the efficiency of the code scanning operation, in one embodiment, two first X-axis linear modules 314 are arranged side by side on the X-axis positioning bracket 313. The two first X-axis linear modules 314 are installed on the X-axis positioning bracket 313 by screws. A Z-axis positioning bracket 315 is installed on each first X-axis linear module 314, and a second Z-axis cylinder 316 is fixed on the Z-axis positioning bracket 315. In this way, two code scanners 300 are installed on the code scanning drive structure 310 at the same time to simultaneously perform code scanning operations on two products arranged side by side on the carrier plate 120, so as to improve the operation efficiency.

[0049] For the above-mentioned code scanning unit 1, after the operator confirms that the equipment is normal, only need to press the start button on the electrical switch panel 740 of the code scanning workbench 700, and the code scanning unit 1 will sequentially complete the operations of picking up the product, positioning, and code scanning. The code scanning information is sent to the first controller or sent to the workshop production control center to realize automatic code scanning. In this way, the production efficiency can be increased by 80% and 8 workers can be reduced.

[0050] Please combine Figures 1-2 and Figures 11-13(The material conveying structure for qualified products is the same as that for unqualified products. The accompanying drawings only exemplify the material conveying structure for qualified products.) The material conveying structure 400 for qualified products includes a qualified product belt support 410 fixed on the upper surface of the sorting and merging line workbench 800, a qualified product conveying belt 420 disposed on the qualified product belt support 410 and extending along the length direction of the sorting and merging line workbench 800, a qualified product driving pulley 430 rotatably connected to the qualified product belt support 410 and driving the rotation of the qualified product conveying belt 420, at least one qualified product driven pulley 440 rotatably connected to the qualified product belt support 410 and jointly tensioning the qualified product conveying belt 420 with the qualified product driving pulley 430, and a first driving motor 450 connected to the qualified product driving pulley 430 to drive the rotation of the qualified product driving pulley 430. The material conveying structure 500 for unqualified products includes an unqualified product belt support 510 fixed on the upper surface of the sorting and merging line workbench 800, an unqualified product conveying belt 520 disposed on the unqualified product belt support 510 and parallel and opposite to the qualified product conveying belt 420, an unqualified product driving pulley rotatably connected to the unqualified product belt support 510 and driving the rotation of the unqualified product conveying belt 520, at least one unqualified product driven pulley 530 rotatably connected to the unqualified product belt support 510 and jointly tensioning the unqualified product conveying belt 520 with the unqualified product driving pulley, and a second driving motor connected to the unqualified product driving pulley to drive the rotation of the unqualified product driving pulley. Preferably, vertical brackets 540 are fixed at the bottoms of the qualified product belt support 410 and the unqualified product belt support 510 to raise the heights of the qualified product belt support 410 and the unqualified product belt support 510, so as to adapt to the height of the sheet picking structure 600 and avoid interference between the qualified product conveying belt 420 and the unqualified product conveying belt 520 and the sorting and merging line workbench 800. In this embodiment, a first driving gear 451 is provided on the output shaft of the first driving motor 450, a first driven gear 452 is coaxially fixed on the qualified product driving pulley 430, and a first synchronous belt 453 is spanned between the first driving gear 451 and the first driven gear 452 to achieve belt transmission between the qualified product driving pulley 430 and the first driving motor 450; a second driving gear is provided on the output shaft of the second driving motor, a second driven gear is coaxially fixed on the unqualified product driving pulley, and a second synchronous belt is spanned between the second driving gear and the second driven gear to achieve belt transmission between the unqualified product driving pulley and the second driving motor.)

[0051] Further, in this embodiment, a plurality of qualified product conveyor belt driven pulleys 440 are provided at the input end of the qualified product conveyor belt 420, including a first driven pulley 441, at least two second driven pulleys 442 arranged side by side above the first driven pulley 441, and a third driven pulley 443 located between the first driven pulley 441 and the second driven pulleys 442 and arranged in a staggered manner with the second driven pulleys 442. The first driven pulley 441 and the second driven pulleys 442 are in contact with the inner side surface of the qualified product conveyor belt 420, and the third driven pulley 443 is in contact with the outer side surface of the qualified product conveyor belt 420. The third driven pulley 443 and two adjacent second driven pulleys 442 jointly enclose a first lifting plate receiving area 444, and the area enclosed by the plurality of second driven pulleys 442 constitutes a qualified product buffer area. The qualified product conveying structure 400 further includes a third Z-axis cylinder 460 arranged beside the qualified product conveyor belt 420, and a first lifting plate 470 located above the third Z-axis cylinder 460 and fixedly connected to the piston rod of the third Z-axis cylinder 460. The first lifting plate 470 enters the first lifting plate receiving area 444 under the drive of the third Z-axis cylinder 460, or moves upward and leaves the first lifting plate receiving area 444 under the drive of the third Z-axis cylinder 460 to support the qualified product to be transported. The third Z-axis cylinder 460 and the first lifting plate 470 jointly constitute a qualified product buffer support mechanism. In this way, when there is one product placed in the qualified product buffer area, the third Z-axis cylinder 460 controls the first lifting plate 470 to rise to lift the product, so that the product leaves the qualified product conveyor belt 420. In this case, products can still be stacked on the first lifting plate 470, realizing the stacking of products without affecting the transportation of products on the qualified product conveyor belt 420. When the number of stacked products reaches a preset value (for example, 30 pieces), the third Z-axis cylinder 460 controls the first lifting plate 470 to descend, so that the first lifting plate 470 retracts into the first lifting plate receiving area 444, and the stacked products return to the qualified product conveyor belt 420 for transportation of the products.

[0052] The input end of the defective product conveying belt 520 is provided with multiple defective product driven pulleys 530, including a fourth driven pulley, at least two fifth driven pulleys arranged side by side above the fourth driven pulley, and a sixth driven pulley located between the fourth driven pulley and the fifth driven pulley and staggered with the fifth driven pulley. The fourth driven pulley and the fifth driven pulley abut against the inner side surface of the defective product conveying belt 520, the sixth driven pulley abuts against the outer side surface of the defective product conveying belt 520, the sixth driven pulley and the two adjacent fifth driven pulleys together form a second lifting plate receiving area, and the area surrounded by multiple fifth driven pulleys constitutes a defective product buffer area. The defective product transport structure 500 also includes a fourth Z-axis cylinder disposed beside the defective product transport belt 520, and a second lifting plate located above the fourth Z-axis cylinder and fixedly connected to the piston rod of the fourth Z-axis cylinder; the second lifting plate enters the second lifting plate receiving area under the drive of the fourth Z-axis cylinder, or moves up and leaves the second lifting plate receiving area under the drive of the fourth Z-axis cylinder to support the defective products to be transported. The fourth Z-axis cylinder and the second lifting plate together constitute a defective product buffer support mechanism. In this way, when a piece of product is placed in the defective product buffer area, the fourth Z-axis cylinder controls the second lifting plate to rise to lift the product so that the product leaves the defective product transport belt 520. In this case, the product can still be stacked on the second lifting plate to achieve product stacking, which does not affect the transportation of the product on the defective product transport belt 520. When the number of stacked products reaches a preset value (e.g., 30 pieces), the fourth Z-axis cylinder controls the second lifting plate to descend, so that the second lifting plate retracts into the second lifting plate receiving area, and the stacked products return to the unqualified product conveying belt 520 for transportation. By stacking the products, the site area occupied by material stacking is saved, and manual stacking is replaced, reducing the labor intensity of the operators.

[0053] In this embodiment, the qualified product driving pulley and the third driven pulley 443 are located at the same height, and the qualified product driving pulley is arranged on a side of a second driven pulley 442 away from the third driven pulley 443, the qualified product driving pulley abuts against the outer side of the qualified product conveying belt 420, and another second driven pulley 442 with the same height as the second driven pulley 442 is arranged on the side of the qualified product driving pulley away from the second driven pulley 442, so that the qualified product driving pulley and its two adjacent second driven pulleys 442 together form another first lifting plate receiving area 444, so that the third Z-axis cylinder 460 can lift two first lifting plates 470 at the same time to increase the receiving area for the product and improve the stability of the product when stacking. Correspondingly, the same arrangement can also be made on the unqualified product conveying belt 520, so that two second lifting plates can be arranged at the same time to improve the stability of the unqualified product when stacking, which will not be repeated here.

[0054] In addition, a first baffle 411 is provided at the output end of the qualified product conveying belt 420 on the qualified product belt support 410, and a second photoelectric sensor electrically connected to the first drive motor 450 is provided; a second baffle 511 is provided at the output end of the unqualified product conveying belt 520 on the unqualified product belt support 510, and a third photoelectric sensor electrically connected to the second drive motor is provided. By providing the first baffle 411, it is possible to prevent the product from falling off the end of the qualified product conveying belt 420 when it moves to the end of the qualified product conveying belt 420. By providing the second photoelectric sensor, when it detects that there is a product at the end of the qualified product conveying belt 420, the first drive motor 450 controls the qualified product conveying belt 420 to stop rotating. When the operator removes the product in this area, the second photoelectric sensor sends a signal to the first drive motor 450 again, so that the qualified product conveying belt 420 runs again to transport the next stack of products, and the cycle continues. Similarly, the function of the second baffle 511 is the same as that of the first baffle 411, and the function of the third photoelectric sensor is the same as that of the second photoelectric sensor. The difference is that the former acts on the qualified product and the qualified product conveying belt 420, and the latter acts on the unqualified product and the unqualified product conveying belt 520, which will not be elaborated here.

[0055] In one embodiment, the code scanning and merging / splitting line mechanism further includes a transfer unit 900. The transfer unit 900 includes a transfer bracket 910 mounted across the code scanning workbench 700 and the merging / splitting line workbench 800, a third X-axis guide rail 920 fixed to the top of the transfer bracket 910 and extending along the length direction of the code scanning workbench 700 and the merging / splitting line workbench 800, a transfer support plate 930 slidably disposed on the third X-axis guide rail 920 and used to receive the products sent by the sheet transferring structure 200, and a third X-axis driving member 940 for driving the transfer support plate 930 to move between the sheet transferring structure 200 and the sheet taking structure 600. The third X-axis guide rail 920 extends in the X-axis direction. The third X-axis driving member 940 may include a lead screw fixed to the third X-axis guide rail 920, a nut threadedly sleeved on the lead screw and slidably engaged with the third X-axis guide rail 920 through a guide rod, and a motor for driving the lead screw to rotate. The transfer support plate 930 is fixed to the nut; or the third X-axis guide rail 920 and the third X-axis driving member 940 together form a linear module, and the transfer support plate 930 is fixed to the movable part of the linear module to achieve the driving of the transfer support plate 930. In this way, after the product is scanned, the first Y-axis linear module 130 drives the product to move below the sheet transferring structure 200. The suction groove 124 of the bearing plate 120 is disconnected from the external vacuum device to release the adsorption of the product. Subsequently, the X-axis positioning post 123 and the Y-axis positioning post 122 are controlled to leave the bearing plate 120 to release the constraint on the product. Subsequently, the first suction cup 260 of the sheet transferring structure 200 descends and adsorbs the product and then lifts up. The second X-axis driving member 240 drives the first suction cup 260 and the product to move towards the direction close to the transfer support plate 930 until the product moves above the transfer support plate 930. Then the first suction cup 260 descends and places the product on the transfer support plate 930. Immediately afterwards, the third X-axis driving member 940 drives the transfer support plate 930 to move towards the direction close to the sheet taking structure 600 until the product moves below the sheet taking structure 600 to achieve the transfer of the scanned product.

[0056] Please refer to Figures 1-2 , Figure 11 and Figures 14-15, the sheet taking structure 600 includes a sheet taking bracket 610 straddling the qualified product conveying belt 420 and the unqualified product conveying belt 520 and fixedly connected to the sorting and merging line workbench 800, a third Y-axis linear module 620 fixed on the sheet taking bracket 610, a Z-axis linear module 640 fixedly connected to the movable part 630 of the third Y-axis linear module and slidable along the width direction of the sorting and merging line workbench 800, a material grasping bracket 650 fixedly connected to the movable part of the Z-axis linear module 640 and slidable along the vertical direction, a rotation driving part 660 fixed on the material grasping bracket 650, a rotation bracket 670 fixed on the rotating part of the rotation driving part 660 and rotatable in the horizontal plane, at least one fifth Z-axis cylinder 680 fixed on the rotation bracket 670, a second suction cup mounting bracket 681 fixedly connected to the piston rod of the fifth Z-axis cylinder 680, and at least one second suction cup 690 fixed on the second suction cup mounting bracket 681 and communicated with an external vacuum device. In this embodiment, the first controller is electrically connected to the second controller. After receiving the signal sent by the barcode scanner 300, the first controller further sends a signal to the first controller to control the operation of the sheet taking structure 600. In other words, it can also be understood that the barcode scanner 300 realizes signal connection with the sheet taking structure 600 through the first controller and the second controller to pick up the scanned products. The rotation driving part 660 can be a rotation motor, which is used to control the rotation of the second suction cup mounting bracket 681 when the second suction cup 690 moves along the Y-axis to the upper part of the corresponding belt, so as to adjust the angle of the products adsorbed on the second suction cup 690, so that all products can be placed on the belt in the same posture. In addition, a corresponding image acquisition device is further provided on the sheet taking bracket 610, and the image acquisition device can be a CCD camera.

[0057] Specifically, when the barcode scanner 300 finishes scanning the product and the product moves on the transfer support plate 930 to below the chip picking bracket 610, the second controller receives the signal sent by the first controller and controls the third Y-axis linear module 620 to operate, so that the Z-axis linear module 640 moves along the Y-axis direction until the second suction cup 690 moves above the product. Subsequently, the fifth Z-axis cylinder 680 controls the second suction cup 690 to descend until the second suction cup 690 contacts the product. The second suction cup 690 then connects to an external vacuum device and adsorbs the product by negative pressure. After the second suction cup 690 adsorbs the product, the fifth Z-axis cylinder 680 controls the second suction cup 690 and the product to rise, and the third Y-axis linear module 620 further controls the product to move to the image acquisition device to collect the product image information to determine the current angle of the product. After the image acquisition device transmits the image signal to the second controller, the second controller controls the rotation drive member 660 to operate to adjust the product angle. Subsequently, the third Y-axis linear module 620 moves the product along the Y-axis direction to the qualified product conveying belt 420 or the unqualified product conveying belt 520 according to the barcode information received by the first controller (the qualified product conveying belt 420 and the unqualified product conveying belt 520 are actually arranged side by side along the Y-axis direction. When the product moves above the corresponding belt, the fifth Z-axis cylinder 680 controls the second suction cup 690 to descend. When the product contacts the corresponding belt, the second suction cup 690 disconnects from the external vacuum device to release the restraint of the second suction cup 690 on the product and accurately place the scanned product on the corresponding belt.

[0058] After the products are classified at the sorting unit 2, before the operator packages the corresponding qualified and unqualified products, it is necessary to manually scan the label on the packaging bag so that the packaging bag is bound to the corresponding conveying belt. During the product classification process, the second controller receives the OK and NG signals (i.e., qualified and unqualified signals) of the barcode scanning operation sent by the first controller. At this time, the chip picking structure 600 starts and grabs the products that have completed barcode scanning. According to the two-dimensional code information and the NG and OK signals, the chip picking structure 600 classifies and moves the products to the designated conveying belts. Each conveying belt can hold six copies, with 30 products in each copy. When there are 6 copies, a total of 180 products are placed on the belt, and the equipment prompts for material collection. Before material collection, the operator needs to scan the label of the packaging bag corresponding to the conveying belt again. After rechecking and finding no abnormalities, the conveying belt starts to operate and discharge materials.

[0059] In addition, it should be noted that there is also a mode switch on the code scanning workbench 700 and the merging and splitting workbench 800 of the code scanning and merging and splitting line mechanism in this embodiment. This mode switch consists of a shielding button (which converts the automatic mode to the manual mode) and an automatic connection button (which converts the manual mode to the automatic mode). In the automatic mode, only one person is needed for packing. Each single device can save 8 laborers, and the device has many advantages such as a small external volume and space saving. When a device failure occurs in the code scanning unit 1 or the merging and splitting unit 2, resulting in the inability of the device to be fully automatically connected, switch to the manual mode. The product with the film covered can be manually cut and carried, then manually scanned, and then the qualified products and unqualified products can be classified manually and put into the packaging bags. If only the code scanning unit 1 fails, the code scanning function can be shielded with one key (i.e., operate the shielding button on the code scanning workbench 700), the side channel is started, the product with the film covered is transported to the merging and splitting unit 2 through the belt, and after manual material collection, manual code scanning is carried out, and the qualified products and unqualified products are classified manually and put into the packaging bags.

[0060] To improve the operation efficiency, in this embodiment, two production lines are simultaneously arranged at the output end of the film laminating machine 3. Each production line includes a code scanning unit 1 and a merging and splitting unit 2. In this way, through the parallel operation of the two production lines, the code scanning and classification efficiency of the product after film lamination can be greatly improved, and the operation efficiency can be enhanced. In actual operation, the code scanning units 1 of the two production lines operating in parallel can share the same code scanning workbench 700, and the merging and splitting units 2 of the two production lines operating in parallel can share the same merging and splitting workbench 800, which will not be elaborated here.

[0061] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0062] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
