[0001] The present invention relates to the technical field of circuit board manufacturing, and in particular to an automatic loading and unloading device for a flexible circuit board. Background Art

[0002] Traditionally, when printing on a flexographic board (flexible circuit board) using an inkjet printer, a cleaning roller brush is first placed on a sticky pad for cleaning, followed by a cleaning roller brush to clean the surface of the flexographic board.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0035] Traditionally, when using an inkjet printer to print ink on flexographic plates, manual loading and unloading is often performed. This has the following drawbacks: one person per machine, resulting in low production efficiency and high labor costs; the process is cumbersome, requiring high operator labor intensity, and missed steps can easily lead to quality risks; and the high printing precision required can cause the operator to manually place the plate incorrectly, resulting in printing deviations, which can affect product yield and increase product scrap costs. To address these technical issues, the present invention proposes an automatic loading and unloading device for flexographic plates.

[0036] like Figure 1 and Figure 2 As shown, the present invention provides an automatic loading and unloading device for flexographic plates, which is applicable to inkjet printers. The automatic loading and unloading device can automatically load and unload flexible circuit boards (i.e., flexographic plates), automatically transport the flexographic plates to the inkjet printer for printing, and automatically unload and store the printed flexographic plates.

[0037] Specifically, the flexible plate automatic loading and unloading equipment may include a material loading and unloading device 10 and a material receiving device 20. The material receiving device 20 may include a receiving frame 700, a receiving forklift mechanism 800 provided on the receiving frame 700, and a receiving net car 900 corresponding to the receiving forklift mechanism 800; the material loading and unloading device 10 may include a loading and unloading frame 100 arranged side by side with the receiving frame 700, a material loading platform 200 provided on the loading and unloading frame 100, a material retrieving mechanism 400, a material cleaning mechanism 500 corresponding to the material retrieving mechanism 400, and a loading and unloading manipulator 600 corresponding to the material cleaning mechanism 500, and the loading and unloading manipulator 600 further corresponding to the receiving net car 900.

[0038] The flexible circuit board (i.e., flexographic board) to be printed can be placed on the material loading platform 200 of the material loading and unloading device 10 first, and the flexographic board on the material loading platform 200 can be automatically picked up by the material picking mechanism 400, and the flexographic board can be moved to the material cleaning mechanism 500 for cleaning, and then the cleaned flexographic board can be grabbed by the loading and unloading robot 600 and moved to the designated area of ​​the ink printing machine, and the printing platform of the ink printing machine can be made to absorb the flexographic board to print ink on it, and then the printed flexographic board can be automatically unloaded by the loading and unloading robot 600, and the printed flexographic board can be moved to the receiving net car 900 placed on the receiving forklift mechanism 800 of the material receiving device 20, and the printed flexographic boards can be placed in layers by the receiving net car 900. After the receiving net car 900 is full of flexographic boards, the receiving net car 900 and the flexographic boards can be transported away.

[0039] In this way, during the printing process of the flexographic plate, the flexographic plate can be automatically loaded and unloaded through the flexographic plate automatic loading and unloading equipment, which can improve production efficiency, reduce labor costs and labor intensity of operators, and will not omit operation steps to cause quality risks. The automatic plate picking and placing has high accuracy, and will not cause printing deviation due to inadequate placement of the plate, affecting product yield. The product quality is guaranteed and product scrap is reduced.

[0040] Furthermore, if Figure 3 and Figure 5As shown, the material retrieving mechanism 400 may include a retrieving translation drive structure 410 provided on the loading and unloading frame 100, a retrieving lifting drive structure 420 provided on the retrieving translation drive structure 410, and a retrieving suction structure 430 provided on the retrieving lifting drive structure 420. The retrieving suction structure 430 corresponds to and cooperates with the material loading platform 200 and the material cleaning mechanism 500. The retrieving suction structure 430 can adsorb the flexible plate, and the retrieving translation drive structure 410 can drive the retrieving lifting drive structure 420 and the retrieving suction structure 430 to reciprocate between the material loading platform 200 and the material cleaning mechanism 500, while the retrieving lifting drive structure 420 can drive the retrieving suction structure 430 to move up and down. When the material picking mechanism 400 transfers the flexible plate, it can first move the material picking adsorption structure 430 to the top of the material loading platform 200 through the material picking translation drive structure 410, and then lower the material picking adsorption structure 430 to the height of the flexible plate on the material loading platform 200 through the material picking lifting drive structure 420, absorb the flexible plate through the material picking adsorption structure 430, and then lift the material picking adsorption structure 430 and the flexible plate adsorbed by it through the material picking lifting drive structure 420, and then transfer the material picking adsorption structure 430 and the flexible plate to the top of the material cleaning mechanism 500 through the material picking translation drive structure 510, and then lower the material picking adsorption structure 430 and the flexible plate through the material picking lifting drive structure 420, and make the material picking adsorption structure 430 release the adsorbed flexible plate and place it on the material cleaning mechanism 500 for cleaning.

[0041] In this embodiment, the material picking translation drive structure 410 may include a translation bracket protruding from the loading and unloading frame 100, a material picking translation slide rail horizontally mounted on the translation bracket, a translation slide frame slidably mounted on the material picking translation slide rail, and a translation drive member mounted on the loading and unloading frame and connected to the translation slide frame. The material picking lifting drive structure 420 may be mounted on the translation slide frame. The translation bracket allows the material picking adsorption structure 430 to be positioned above the loading and unloading frame 100, facilitating the picking and transport of the flexible plate on the material loading platform 200. Furthermore, the translation drive member can drive the translation slide frame and the material picking lifting drive structure 420 to reciprocate horizontally along the material picking translation slide rail. The material picking translation slide rail is disposed between the material loading platform 200 and the material cleaning mechanism 500, allowing the translation slide frame and the material picking lifting drive structure 420 to reciprocate between the material loading platform 200 and the material cleaning mechanism 500.

[0042] Furthermore, the reclaiming lifting drive structure 420 may include a reclaiming lifting rail vertically mounted on a translating carriage, a lifting carriage slidably mounted on the reclaiming lifting rail, and a lifting drive member mounted on and connected to the translating carriage. The reclaiming suction structure 430 is mounted on the lifting carriage. The lifting drive member can drive the lifting carriage to vertically move up and down along the reclaiming lifting rail, thereby driving the reclaiming suction structure 430 to move up and down, thereby facilitating the lifting and lowering of the flexible plate. Furthermore, both the lifting drive member and the translating drive member can be configured as motor-driven structures or cylinder-driven structures.

[0043] Furthermore, the retrieving and adsorption structure 430 may include a retrieving panel frame 432 mounted on the lifting carriage of the retrieving and elevating drive structure 420, and multiple vacuum adsorption heads 434 mounted on the retrieving panel frame 432. Each of the multiple vacuum adsorption heads 434 can be connected to a vacuum extraction device. By arranging multiple vacuum adsorption heads 434 on the retrieving panel frame 432, a retrieving and adsorption panel is formed, facilitating the adsorption of planar flexible plates. Furthermore, the multiple vacuum adsorption heads 434 can be used to adsorb one or more flexible plates, allowing for the simultaneous transport of multiple flexible plates.

[0044] In addition, the material cleaning mechanism 500 may include a material cleaning platform 510 disposed on the loading and unloading frame 100, and a roller brush cleaning mechanism 520 corresponding to the material cleaning platform 510. The material retrieving and adsorption structure 430 corresponds to the material cleaning platform 510, and the material loading platform 200 and the material cleaning platform 510 may be correspondingly disposed on both sides of the top of the loading and unloading frame 100. The material retrieving mechanism 400 can transfer the flexographic plate placed on the material loading platform 200 to the material cleaning platform 510 of the material cleaning mechanism 500. The roller brush cleaning mechanism 520 corresponding to the material cleaning platform 510 can then clean the flexographic plate on the material cleaning platform 510, facilitating subsequent printing on the flexographic plate.

[0045] Furthermore, the material cleaning platform 510 may include a cleaning positioning plate mounted on the loading and unloading frame 100, and a positioning adsorption structure disposed at the bottom of the cleaning positioning plate. The cleaning positioning plate is provided with a plurality of adsorption positioning holes corresponding to the positioning adsorption structure. When the flexible plate is placed on the cleaning positioning plate of the material cleaning platform 510, the positioning adsorption structure can be positioned on the cleaning positioning plate by adsorption through the plurality of adsorption positioning holes provided in the cleaning positioning plate, facilitating cleaning of the flexible plate by the roller brush cleaning mechanism 520.

[0046] Furthermore, the roller brush cleaning mechanism 520 may include a cleaning bracket 522 slidably mounted on the loading and unloading frame 100, a roller brush lifting drive structure 524 mounted on the cleaning bracket 522, a cleaning roller brush 526 connected to the roller brush lifting drive structure 524, and a bracket translation drive member 528 mounted on the loading and unloading frame 100. The bracket translation drive member 528 is connected to the cleaning bracket 522, and the cleaning roller brush 526 is positioned above the cleaning positioning plate. The bracket translation drive member 528 can drive the cleaning roller brush 526 to move along the length of the cleaning positioning plate of the material cleaning platform 510, while the roller brush lifting drive structure 524 can drive the cleaning roller brush 526 to move up and down, thereby pressing or releasing the flexible plate on the cleaning positioning plate, thereby facilitating cleaning of the flexible plate by the cleaning roller brush 526.

[0047] Furthermore, the roller brush cleaning mechanism 520 may include two cleaning rails arranged side by side on the loading and unloading frame 100, with a cleaning positioning plate located between the two cleaning rails. Furthermore, the cleaning bracket 522 may include two side brackets and a main bracket arranged between the two side brackets, so that the cleaning bracket forms a U-shaped bracket. Furthermore, the two side brackets of the cleaning bracket 522 are slidably mounted on the two cleaning rails in a one-to-one correspondence, and the roller brush lifting drive structure 524 is located on the main bracket. In this embodiment, the bracket translation drive member 528 may be a motor-driven structure or a cylinder-driven structure.

[0048] Furthermore, the roller brush lift drive structure 524 may include a roller brush lift drive member mounted on the main support of the cleaning bracket 522, and a roller brush lift frame connected to the roller brush lift drive member. The roller brush lift frame is slidably mounted on the main support, and the cleaning roller brush 526 may be mounted on the roller brush lift frame. In this embodiment, the roller brush lift frame may include a guide frame vertically slidably mounted on the main support, and a roller brush connecting frame connected to the guide frame. The cleaning roller brush 526 is mounted at the bottom of the roller brush connecting frame, and the roller brush lift drive member is connected to the top of the roller brush connecting frame. Furthermore, the roller brush lift drive member may be a drive cylinder fixed to the main support, with a cylinder rod of the drive cylinder connected to the top of the roller brush connecting frame. The drive cylinder can be used to drive the roller brush connecting frame and the cleaning roller brush 526 to rise and fall, thereby causing the cleaning roller brush 526 to abut against the flexible plate on the cleaning positioning plate.

[0049] Furthermore, the material loading and unloading device 10 may also include a product positioning detection mechanism 110 and a temporary storage platform for abnormal products 300, which are located on the top surface of the loading and unloading frame 100. The loading and unloading robot 600 corresponds to the product positioning detection mechanism 110 and the temporary storage platform for abnormal products 300. After the flexographic plate is cleaned by the cleaning roller 526, it can be moved to the inkjet printer by the loading and unloading robot 600 for printing.

[0050] In this embodiment, the product positioning detection mechanism 110 can be configured as an industrial positioning camera (CCD camera). Before the loading and unloading robot 600 grabs the flexographic plate and moves it to the inkjet printer, the industrial positioning camera can be used to accurately position the loading and unloading robot 600 so that the loading and unloading robot 600 and the flexographic plate are accurately aligned, avoiding deviation when grabbing the flexographic plate, thereby accurately placing the flexographic plate in a designated area of ​​the printing platform of the inkjet printer for printing. Moreover, when the ink printing machine itself detects that the position of the flexographic plate placed on the printing platform is offset, the flexographic plate can be regarded as an abnormal product, and an alarm can be issued to prompt the loading and unloading robot 600 to remove the flexographic plate from the printing platform and place it on the abnormal product temporary storage table 300; and, if the ink printing machine is provided with a flexographic plate identification device (such as a code scanning device), if the flexographic plate placed on the printing platform fails to be correctly identified (such as the scanning device fails to identify the identification code (such as a QR code) on the flexographic plate), the flexographic plate can also be regarded as an abnormal product, and the flexographic plate can be removed by the loading and unloading robot 600 and placed on the abnormal product temporary storage table 300.

[0051] Furthermore, the loading and unloading robot 600 may include a multi-degree-of-freedom robotic arm mounted on the loading and unloading frame 100, and a robotic suction plate mounted on the robotic arm. The robotic arm can drive the robotic suction plate to move in various directions within a rectangular coordinate system, and the robotic suction plate can be used to absorb and release the flexible plate, thereby transferring the flexible plate from the material cleaning platform 510 to the receiving network vehicle 900. The specific structure of the robotic suction plate is similar to that of the material retrieving suction structure and will not be further described here.

[0052] In addition, if Figure 6 and Figure 8 As shown, the receiving frame 700 of the material receiving device 20 may include a main receiving frame 710 and a receiving frame side plate 720 protruding from one side of the main receiving frame 710. The receiving forklift mechanism 800 may be provided on the main receiving frame 710, and the loading and unloading frames 100 of the material loading and unloading device 10 may be provided side by side on the other side of the main receiving frame 710. A material receiving space is formed between the loading and unloading frames 100 and the receiving frame side plate 720, and the receiving net car 900 may be placed in the material receiving space, so that it can be lifted and lowered by the receiving forklift mechanism 800, and the receiving net car 900 can reach a suitable height to facilitate the receiving of the printed flexo plate (the printed flexo plate can be transferred to the receiving net car 900 by the loading and unloading manipulator 600).

[0053] Furthermore, the receiving forklift mechanism 800 may include a forklift lifting drive structure 810 provided on the receiving frame 700, and a forklift 820 connected to the forklift lifting drive structure 810. The forklift 820 is located in the material receiving space between the loading and unloading frame 100 and the receiving frame side plate 720. The forklift lifting drive structure 810 can drive the forklift 820 to move up and down between the bottom and the top of the material receiving space, thereby lifting and moving the receiving net car 900 placed on the forklift 820, thereby lifting and moving the flexible plate placed in the receiving net car 900.

[0054] Furthermore, the forklift lift drive structure 810 may include a drive motor 812 disposed on the top of the main supporting frame 710 of the supporting frame 700, and a chain lift transmission structure 814 connected to the output shaft of the drive motor 812. The fork 820 is connected to the chain lift transmission structure 814, which is disposed on the side of the main supporting frame 710. The drive motor 812 can drive the chain lift transmission structure 814 to operate, so that the chain lift transmission structure 814 drives the fork 820 to move up and down.

[0055] The fork 820 may include a main fork body 822 connected to a chain lift transmission structure 814, and two parallel fork arms 824 protruding from the main fork body 822. The chain lift transmission structure 814 can drive the main fork body 822 to move up and down along the main support frame 710, thereby driving the two fork arms 824 to move up and down, thereby driving the receiving net vehicle 900 placed on the two fork arms 824 to move up and down. Furthermore, the main fork body 822 can be slidably mounted on the side of the main support frame 710, ensuring stable and reliable movement of the fork 820.

[0056] Furthermore, the chain lifting transmission structure 814 may include a driving sprocket connected to the output shaft of the driving motor 812, a driven sprocket corresponding to the driving sprocket, and a transmission chain connected between the driving sprocket and the driven sprocket. The main fork body may be connected to the transmission chain, and the driving sprocket and the driven sprocket may be rotatably mounted on the main support frame 710. The driving motor 812 can drive the driving sprocket to rotate, thereby driving the transmission chain to move, thereby driving the fork 820 to move up and down.

[0057] Furthermore, the forklift receiving mechanism 800 may include a net car fixing structure 830 disposed on the fork 820. The net car fixing structure 830 can sense and secure the receiving net car 900 placed on the fork arm 824 of the fork 820, ensuring stability and reliability when receiving the net car. Specifically, the net car fixing structure 830 may include a net car sensor 832 and a net car fixing clamp 834 disposed on the fork arm 824 of the fork 820, as well as a clamp driving structure 836 connected to the net car fixing clamp 834. When the net car sensor 832 senses that the receiving net car 900 is placed on the fork arm 824, the clamp driving structure 836 can drive the net car fixing clamp 834 to grasp the receiving net car 900, thereby securing the receiving net car 900.

[0058] In this embodiment, the net car sensor 832 can be configured as a travel switch. Furthermore, the net car sensor 832 can be located on the fork arm 824 at the location where it connects to the main fork body 822, i.e., near the main receiving frame 710 inside the material receiving space, so that the net car sensor 832 is triggered only when the receiving net car 900 is placed in place. The clamp drive structure 836 can include a drive cylinder or a drive motor, and the fixed clamp 834 can include two clamping plates connected to the drive cylinder or drive motor. The drive cylinder or drive motor can drive the two clamping plates toward or away from each other, thereby clamping or releasing the bottom of the receiving net car 900. Alternatively, the fixed clamp 834 can include a clamping plate connected to the drive cylinder or drive motor, with a hook provided on the clamping plate. Driven by the drive cylinder or drive motor, the clamping plate can engage or release the receiving net car 900 through the hook.

[0059] Furthermore, the forklift receiving mechanism 800 may include a limiting structure 840 disposed at the bottom of the receiving frame 700. The limiting structure 840 may be disposed on both sides of the main receiving frame 700, thereby limiting the receiving net vehicle 900 from both sides of the material receiving space. Specifically, the limiting structure 840 may include a limiting rod 842 protruding from each side of the bottom of the receiving frame 700, and a plurality of sliding limiting wheels 844 vertically arranged side by side on each limiting rod 842. The two fork arms 824 of the fork 820 are located between the two limiting rods 842. One of the limiting rods 842 can be located at the bottom of the receiving frame side plate 720 of the receiving frame 700, extending along the bottom of the receiving frame side plate 720 and arranged side by side with the fork arm 824; the other limiting rod 842 protrudes from the bottom of the main receiving frame 710 of the receiving frame 700 and is arranged side by side with the fork arm 824. The two limiting rods 842 are arranged opposite each other. When the receiving net car 900 is pushed into the material receiving space, the limiting rods 842 on both sides can limit the receiving net car 900, and the sliding limiting wheels 844 on the limiting rods 842 can slide and limit the receiving net car 900, which is conducive to pushing the receiving net car 900 into the material receiving space.

[0060] In addition, the receiving forklift mechanism 800 may include a lever mechanism 850 provided on the receiving frame 700, and the lever mechanism 850 corresponds to the receiving mesh car 900. The receiving mesh car 900 may be provided with multiple layers of mesh trays, each of which can be used to place printed flexographic plates. At the initial moment, the receiving forklift mechanism 800 can lift the receiving mesh car 900 to a preset high position, and place the multiple layers of mesh trays in an upward tilted or raised state. When the printed flexographic plates begin to be received, the mesh tray on the bottom layer of the multiple layers of mesh trays can be positioned at a preset height and in a horizontal state, with a gap between the mesh tray on the bottom layer and the mesh tray on the upper layer for placing the plates, so that the loading and unloading robot 600 can move the flexographic plates into the convenient gap and place the flexographic plates on the horizontal mesh trays.

[0061] When the bottom mesh tray is fully loaded with flexographic plates, the receiving forklift mechanism 800 drives the receiving mesh trolley 900 to descend to a preset height, causing the bottom mesh tray to descend to the lower position of the receiving mesh trolley 900. Simultaneously, the lever mechanism 850 shifts the mesh tray above the bottom mesh tray, causing it to drop to the higher position of the receiving mesh trolley 900 to once again hold the printed flexographic plates. The above steps are repeated until the entire receiving mesh trolley 900 is fully loaded with flexographic plates. When the mesh tray of the receiving mesh trolley 900 receives flexographic plates, it can always be at a preset height, facilitating its alignment with the loading and unloading robot 600 to smoothly receive the flexographic plates.

[0062] Furthermore, the lever mechanism 850 may include a lever lifting and driving structure 852 disposed on the receiving side plate 710 of the receiving frame 700, a lever frame 854 disposed on the lever lifting and driving structure 852, and a tray table sensor 856 and a lever structure 858 disposed on the lever frame 854. The tray table sensor 856 and the lever structure 858 both correspond to and cooperate with the receiving mesh vehicle 900. After the mesh tray at the high position is filled with printed flexographic plates, the forklift carrying mechanism 800 drives the receiving mesh vehicle 900 to descend to a preset height, thereby lowering the mesh tray filled with flexographic plates to the low position.

[0063] At the same time, the lever mechanism 850 performs a lift detection. When it detects an empty mesh tray at a higher position on the upper level, it is moved to lower it to a higher position. Specifically, the lever lifting drive structure 852 of the lever mechanism 850 can drive the lever frame 854 to lift, which can drive the tray table sensor 852 and the lever mechanism 858 to lift. When the tray table sensor 856 detects the frame of an empty mesh tray at a higher position on the upper level during the lifting process, the lever mechanism 858 can be moved to lower the mesh tray to a higher position. Furthermore, the lever mechanism 858 can include a lever telescopic drive member disposed on the lever frame 854, and a lever head connected to the lever telescopic drive member. When the toggle rod structure 858 is driven to be lifted by the toggle rod lifting drive structure 852, the toggle rod head can be in a retracted state; when the tray table sensor 856 detects the mesh tray, the toggle rod telescopic drive component can drive the toggle rod head to extend, so that the toggle rod head presses the top surface of the frame of the mesh tray, and drives the toggle rod frame 854 and the toggle rod head to descend through the toggle rod lifting drive structure 852, so as to toggle the mesh tray down to a preset height position.

[0064] Furthermore, the specific structure of the lever lift drive mechanism 852 is similar to that of the chain lift transmission mechanism 814 of the forklift mechanism 800 and will not be further described here. Furthermore, the lever extension drive element can be configured as a drive cylinder. The pallet table sensor 856 can also be configured as a travel switch.

[0065] In addition, the working process of the automatic loading and unloading equipment for flexible plates is as follows:

[0066] S100: First, the layered receiving net car 900 is moved to the material receiving space of the receiving frame 700. The net car sensor 832 of the net car fixing structure 830 of the receiving forklift mechanism 800 is triggered, and the receiving net car 900 is fastened by the net car fixing claw 834.

[0067] S200: Place the arranged flexible plate on the material loading platform 200 of the material loading and unloading device 10, and drive the forklift mechanism 800's fork 820 to lift the receiving net car 900 to the set height under the drive of the forklift lifting drive structure, and the automatic loading and unloading operation begins;

[0068] S300: The material picking and adsorption structure 430 of the material picking mechanism 400 of the material loading and unloading device 10 picks up a flexible plate product from the material loading platform 200; the material picking and translation driving structure 410 of the material picking mechanism 400 delivers the adsorbed flexible plate to the top of the material cleaning platform 510 of the material cleaning mechanism 500; the material picking and lifting driving structure 420 then places the flexible plate on the material cleaning platform 510, and then the material picking mechanism 400 returns to the material loading platform 200;

[0069] S400: The flex plate is fixed by adsorption via the material cleaning platform 510, and then the cleaning roller brush 526 is driven by the bracket translation drive member and the roller brush lifting drive structure of the roller brush cleaning mechanism 520 to clean the surface of the flex plate on the material cleaning platform 510;

[0070] S500: After the flex plate is cleaned, the material cleaning platform 510 releases the fixed flex plate, and moves the manipulator suction plate of the loading and unloading robot 600 to the top of the material cleaning platform 510 to suck the flex plate, and then moves the flex plate to the product positioning detection mechanism 110 to accurately position the product;

[0071] S600: The loading and unloading robot 600 then places the flexographic plate on the printing platform of the ink printer. The loading and unloading robot 600 returns to its initial position, and the printing platform suctions air through the air suction holes to adsorb the flexographic plate onto the printing platform. The ink printer then prints on the flexographic plate.

[0072] Repeating the above steps S300-S600 to print on multiple flexographic plates;

[0073] S700: After printing is completed, the suction holes of the printing platform are closed, and the loading and unloading robot 600 moves to the top of the printing platform, sucks the flexographic plate through the robot's suction plate, and transfers it to the mesh tray on the top layer of the mesh carriage;

[0074] S800. When the flexible plate is placed on the mesh pallet receiving the mesh vehicle, the lever mechanism 850 of the receiving forklift mechanism 800 can be lifted by the lever lifting drive structure 852. When the pallet table sensor 856 of the lever mechanism 850 detects the table frame of the mesh pallet, the lever structure 858 can be driven to move a layer of the mesh pallet, and the fork 820 can be lowered to a specified height.

[0075] Repeat the above steps S700-S800 to fill the receiving network vehicle 900 with flexible panels.

[0076] Furthermore, when abnormal products are detected during the cleaning or printing process, the abnormal products can be placed on the abnormal product temporary placement table 300 .
