[0039] In this embodiment, the feeding unit 1 and the conveying unit 3 are parallel to each other and extend along the Y direction. In other embodiments, the layout can be adjusted according to actual situations.

[0040] The feeding unit 1 includes a first conveying line 11 for conveying the trays and a tray loading station, a tray positioning station and a tray unloading station arranged in sequence along the tray conveying direction. An ascending and separating module 12 for lifting and separating the tray is arranged at the tray loading station, an ascending and positioning module 13 for lifting and positioning the tray is arranged at the tray positioning station, and an ascending and supporting module 14 for lifting and supporting the tray is arranged at the tray unloading station.

[0043] The lifting support module 14 includes a third lifting component for lifting the tray upward and several support components for supporting the tray. The third lifting component includes a third lifting plate 141 and a fifth cylinder 142 for driving the third lifting plate 141 to move up and down. The support component includes a support seat 143 and a support block 144 rotatably arranged on the support seat 143.

[0044] Four positioning posts 15 for positioning the tray are also provided at the tray loading station and the tray unloading station. Guide grooves for positioning the corners of the tray are provided on all four positioning posts, and the four positioning posts form a bin for placing the tray.

[0045] The precise positioning module 2 includes a positioning frame and a positioning carrier 22 arranged on the positioning frame. The positioning carrier 22 is installed at the upper end of the positioning frame by bolts 23. A number of positioning grooves 24 are provided on the positioning carrier 22. The shape of the positioning grooves 24 is set to be similar to that of the FPC board 200, and the layout of the positioning grooves 24 is the same as the layout on the tray. Different positioning carriers 22 can be replaced to adapt to FPC boards 200 of different sizes.

[0046] A number of positioning holes 301 for positioning the FPC board are provided on the steel sheet 300. Since the steel sheet 300 is very thin, it is not convenient for the conveying unit 3 to convey it alone. Therefore, a steel sheet carrier 31 is used to assist in conveying the steel sheet 300. The steel sheet 300 is first placed on the steel sheet carrier 31 and conveyed together with the conveying unit 3. Different steel sheets 300 and different steel sheet carriers 31 can be replaced to adapt to FPC boards 200 of different sizes.

[0047] The conveying unit 3 includes a second conveying line 32 for conveying the steel sheet carrier 31 and the steel sheet 300, and a steel sheet input station, an FPC board positioning station, and a steel sheet output station arranged in sequence along the conveying direction. A first carrier blocking component 37 for blocking the continuous forward conveyance of the steel sheet carrier 31 and a first positioning and lifting mechanism 33 for positioning the steel sheet 300 and lifting the steel sheet 300 upward are provided at the steel sheet input station. The assembling mechanism 4 is arranged at the FPC board positioning station. A second carrier blocking component 38 for blocking the continuous forward conveyance of the steel sheet carrier 31 and a second positioning and lifting mechanism 34 for positioning the steel sheet 300 and lifting the steel sheet upward are provided at the steel sheet output station.

[0048] The first positioning and lifting mechanism 33 and the second positioning and lifting mechanism 34 have the same structure and both include a positioning module 35 for positioning the steel sheet 300 and the steel sheet carrier 31 and a lifting module 36 for lifting the steel sheet on the steel sheet carrier 31 upward.

[0049] The positioning module 35 includes a positioning and guiding component 351 extending into the steel sheet 300 and the steel sheet carrier 31, and a plurality of pressing components 352 pressing on the steel sheet carrier 31. After the second conveyor line 32 conveys the steel sheet in place, the positioning and guiding component 351 positions the steel sheet carrier 31. To fully separate the steel sheet 300 from the steel sheet carrier 31, when the lifting module 36 lifts the steel sheet upward, the pressing component 352 is provided to press on the steel sheet carrier, facilitating the smooth separation of the steel sheet 300 from the steel sheet carrier 31.

[0050] The positioning and guiding component 351 includes a lifting frame 3511, a plurality of positioning pins 3512 provided on the lifting frame 331 and inserted into the steel sheet carrier 31, and a sixth cylinder 3513 driving the lifting frame 331 to move up and down. The pressing component 352 includes an elastic member 3521 and a pressing strip 3522 provided at the upper end of the elastic member 3521 and pressing on the edge of the steel sheet carrier 31.

[0051] The lifting module 36 includes a steel sheet lifting plate 361 and a first motor 362 driving the steel sheet lifting plate 361 to move up and down. A plurality of ejector pins 363 for lifting the steel sheet 300 are provided on the lifting plate 361, and the ejector pins 363 are located between two positioning holes 301 to facilitate lifting the steel sheet 300.

[0052] The first carrier blocking component 37 and the second carrier blocking component 38 have the same structure and both include a sensor 381 for detecting the carrier in place, a carrier blocking plate 382 for blocking the forward conveyance of the carrier, and a seventh cylinder 383 driving the carrier blocking plate 382 to move up and down.

[0053] The assembling mechanism 4 includes an assembling and positioning module 41 for positioning the steel sheet 300 and the FPC board 200, a lifting module 42 provided below the assembling and positioning module 41 to support a plurality of FPC boards 200, and a lifting and separating module 43 provided above the assembling and positioning module 41 to simultaneously lift the steel sheet 300 and the FPC board 200 upward.

[0054] The assembly positioning module 41 includes a positioning plate 412 and a positioning pin assembly 411 disposed on the positioning plate 412 and extending into the positioning holes 301 of the steel sheet 300 to position the FPC board 200. A positioning pin assembly 411 extending vertically is provided at the position where each positioning hole 301 is located. The positioning pin assembly 411 includes a plurality of positioning pins that abut against the inner wall of the positioning hole 301 and surround the outer periphery of the FPC board 200. The layout of the plurality of positioning pins is shaped like the FPC board 200, presenting a regular or irregular annular structure. Each positioning pin assembly 411 surrounds the outer periphery of the FPC board 200. When the steel sheet 300 is positioned on the assembly positioning module 41, the outer ring of each positioning pin assembly 411 abuts against the inner wall of the positioning hole 301 of the steel sheet 300 to complete the positioning of the steel sheet 300. When the FPC board 200 is positioned on the steel sheet 300, the inner ring of each positioning pin assembly 411 abuts against the outer periphery of the FPC board 200 to complete the positioning of the FPC board 200. Therefore, the assembly positioning module 41 can simultaneously complete the positioning of the steel sheet 300 and the FPC board 200.

[0055] The thickness of the FPC board 200 is the same as that of the steel sheet 300. In order to firmly position the FPC board 200 on the steel sheet 300, a mylar film is pasted on the back surface of the steel sheet 300. The mylar film adheres to the back surface of the FPC board, making the positioning of the FPC board and the steel sheet 300 more firm. If the second handling mechanism 7 directly places the FPC board 200 into the positioning hole 301 of the steel sheet 300, due to the adhesiveness of the mylar film, if one end of the FPC board 200 descends first and adheres to the mylar film, it will cause the positioning of the FPC board 200 to shift, affecting the positioning of the FPC board 200. Therefore, a lifting module 42 is provided to first hold up the FPC board 200. The lifting module 42 includes a support plate 421, a plurality of support pin assemblies 422 disposed on the support plate 421 and capable of extending into the positioning holes 301 of the steel sheet 300 to hold up the FPC board 200, and a second motor 423 for driving the support plate 421 to move up and down. A support pin assembly 422 is provided at the position where each positioning hole 301 is located. The support pin assembly 422 includes a plurality of support pins for holding up the FPC board. When the second handling mechanism 7 places the FPC board 200 into the positioning hole 301 of the steel sheet 300, each support pin assembly 422 first holds up the FPC board 200 in each positioning hole 301, and then the second motor 423 drives the support plate 421 to move downward. The support pin assembly 422 drives the FPC board 200 to move downward and be positioned on the mylar film. At this time, the positioning pin assembly 411 in each positioning hole 301 can perform horizontal positioning on the FPC board 200, restricting the movement of the FPC board 200 in the horizontal direction, so that the FPC board 200 in each positioning hole 301 can be smoothly adhered to the mylar film. The pressing handling mechanism 6 further presses to simultaneously and smoothly position a plurality of FPC boards 200 on the steel sheet 300 to obtain an assembled FPC board.

[0056] Since the thickness of the assembled FPC board is very thin, in order for the pressing and handling mechanism 6 to smoothly handle the assembled FPC board, a lifting and separating module 43 is provided above the assembly positioning module 41. The lifting and separating module 43 includes a lifting and separating plate 431 and a lifting drive assembly 432 for driving the lifting and separating plate 431 to move up and down. A first avoidance through-hole for the positioning pin and the supporting pin to pass through is provided on the lifting and separating plate 431. The lifting drive assembly 432 includes a lifting block 4321 and an eighth cylinder 4322 for driving the lifting block 4321 to move up and down.

[0057] The first handling mechanism 5 transports the steel sheet on the steel sheet input station to the FPC board positioning station. The first handling mechanism 5 includes a first YZ-axis drive module 51, a suction frame 52 fixed on the first YZ-axis drive module 51, and a suction plate 53 provided at the lower end of the suction frame 52. Since the steel sheet is adsorbed in this embodiment, the suction plate 53 uses an electromagnetic suction plate, and the suction force can be flexibly adjusted by controlling the magnitude of the current to meet steel sheets 300 of different thicknesses or different sizes.

[0058] The pressing and handling mechanism 6 simultaneously presses and assembles the FPC board on the FPC board positioning station onto the steel sheet 300, and at the same time transports the assembled FPC board to the steel sheet output station. The pressing and handling mechanism 6 includes a second YZ-axis drive module 61, a first gripper frame 62 provided on the second YZ-axis drive module 61, and a pressing and suction module 63 detachably mounted on the first gripper frame 62. The pressing and suction module 63 includes a first mounting plate 631, a plurality of pressing blocks 632, and a plurality of first suction cups 633 provided on the first mounting plate 631.

[0059] Each pressing block 632 is provided with a profiling protrusion 634 that profiles the FPC board 200 and a first guiding hole 635 provided around the profiling protrusion 634 and matching the positioning pin assembly 411. When pressing the FPC board 200, the profiling protrusion 634 is positioned above the FPC board 200 and presses the FPC board 200 into the positioning hole 301 of the steel sheet 300.

[0060] The second transport mechanism 7 simultaneously transports all the FPC boards 200 in the tray on the tray positioning station to the precise positioning module 2 for positioning. After the positioning is completed, all the FPC boards 200 are transported to the lifting module 42 on the FPC board positioning station again. The second transport mechanism 7 includes an XZ-axis driving module 71, a second gripping frame 72 disposed on the XZ-axis driving module 71, and an adsorption module 73 detachably mounted on the second gripping frame 72. The adsorption module 73 includes a second mounting plate 731, a plurality of second suction cups 732 disposed on the second mounting plate 731, a material-diverting plate 733 movably disposed below the second mounting plate 731 and dipping all the FPC boards 200 on the second suction cups 732 downward at the same time, and a dipping component that drives the material-diverting plate 733 to move up and down.

[0061] The material-shifting plate 733 is provided with a second avoidance through hole for the second suction cup 732 to pass through, and the shifting assembly includes a ninth cylinder 736 provided on the second gripper frame 72 and a shifting block 737 driven by the ninth cylinder 736 to move up and down.

[0062] In order to enable the assembly of FPC boards 200 of different sizes, the pressing and adsorption module 63 and the adsorption module 73 can be detachably arranged, so as to facilitate the rapid replacement of the assembly of FPC boards 200 that have been adapted to different sizes. Therefore, quick-change modules are provided on the pressing and transporting mechanism 6 and the second transporting mechanism 7 to facilitate the rapid disassembly and replacement of the pressing and adsorption module 63 and the adsorption module 73.

[0063] The pressing and transporting mechanism 6 is provided with a first quick-change module 65, which includes a tenth cylinder 651 arranged on the first gripper frame 62, a first snap block 652 driven by the tenth cylinder 651 to move up and down, a second snap block 653 fixedly arranged on the first mounting plate 631 and cooperating with the first snap block 652, a guide pin arranged on the first mounting plate 631, and a second guide hole 654 arranged on the first gripper frame 62 and cooperating with the guide pin.

[0064] When replacing the pressing and adsorption module 65, the tenth cylinder 651 drives the first snap block 652 to drive the first mounting plate 631 to descend into place. At the same time, the guide pin disengages from the second guide hole 654. Since the first snap block 652 and the second snap block 653 are snapped in upper and lower steps, the first mounting plate 631 can be moved horizontally outward to disassemble the pressing and adsorption module 63. When replacing the new adsorption and pressing module 65, the second snap block 653 of the first mounting plate 631 is snapped in upper and lower steps with the first snap block 652, and the first mounting plate 631 is moved horizontally inward to be located below the first gripper frame 62. The tenth cylinder 651 drives the first snap block 652 to drive the first mounting plate 631 to rise into place. At the same time, the guide pin enters the second guide hole 654, completing the replacement of the new adsorption and pressing module 65.

[0065] A second quick-change module 75 is provided on the second handling mechanism 7. The structure of the second quick-change module 75 is the same as that of the first quick-change module 65, and the replacement principle is also the same, so it will not be elaborated here.

[0066] When applying the plate planting machine 100 with a quick-change function and high positioning accuracy provided by this solution, a worker or a manipulator places the tray on the tray loading station, places the steel sheet carrier 31 and the steel sheet 300 on the steel sheet input station. The lifting and sorting module 12 moves the bottommost tray onto the first conveyor line 11. The tray is conveyed from the first conveyor line 11 to the lifting and positioning module 13. The second handling mechanism 7 sucks all the FPC boards 200 on the tray and transports them to the precise positioning module 2. All the FPC boards 200 are placed into the positioning grooves 24 on the positioning carrier 22 for positioning and alignment of all the FPC boards 200.
