[0022] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, an automated packaging machine 10 includes: a worktable 100, a tray platform 200, a robotic arm 400, a plate feeding mechanism 500, a tray feeding mechanism 600, and a stacking mechanism 800. A boxing platform 300 is provided on the worktable 100. A stacking cavity 110 is formed on the worktable 100, and a lifting port 120 is formed on the side wall of the stacking cavity 110. The tray platform 200 includes: two placement plates 210, which are slidably disposed on the worktable 100 and aligned with the lifting port 120. The robotic arm 400 is disposed on the worktable 100 and has a suction cup assembly 410. The plate feeding mechanism 500 is spaced apart from the worktable 100. The tray feeding mechanism 600 is disposed on the worktable 100. The pallet feeding mechanism 600 is aligned with the two placement plates 210. The pallet stacking mechanism 800 includes a lifting frame 810, a pallet stacking plate 820, and two first conveyor belts 830. The two first conveyor belts 830 are spaced apart on the bottom of the pallet stacking cavity 110. The lifting frame 810 is raised and lowered on the side wall of the pallet stacking cavity 110. The lifting frame 810 is aligned with the two first conveyor belts 830 and the two placement plates 210 respectively. The pallet stacking plate 820 is raised and lowered in the pallet stacking cavity 110 and is located between the two first conveyor belts 830. A stacking plate 840 is slidably disposed on each first conveyor belt 830. The two stacking plates 840 move towards or away from each other. The movement direction of the pallet stacking plate 820 is perpendicular to the movement direction of the stacking plate 840.

[0023] In this embodiment, a tray platform 200 and a packing platform 300 are spaced apart on the workbench 100. The tray platform 200 is used to place trays, and the packing platform 300 is used to place transfer boxes. The tray feeding mechanism 600 is used to feed trays to the tray platform 200, and the board feeding mechanism 500 is used to feed circuit boards to the workbench 100. The robotic arm 400 can pick up and move the trays on the tray platform 200 and the circuit boards on the board feeding mechanism 500 through its suction cup assembly 410. Meanwhile, a stacking cavity 110 is provided on the workbench 100, and a lifting port 120 is provided on the side wall of the stacking cavity 110. The opening direction of the lifting port 120 is perpendicular to the opening direction of the stacking cavity 110. The lifting frame 810 of the stacking mechanism 800 can move the trays filled with circuit boards on the two placement plates 210 to the two first conveyor belts 830. The first conveyor belt 830 includes: a first conveying guide rail, a first belt and two first pulleys. The two first pulleys are spaced apart on the first conveying guide rail. The first belt rotates around the two first pulleys. By driving one of the first pulleys to rotate by a motor, the trays can be conveyed on the first conveyor belt 830. With the help of the stacking plate 820 and the stacking plate 840, the trays filled with circuit boards can be stacked in sequence.

[0024] In this embodiment, in one working mode of the automated packaging machine 10, the tray feeding mechanism 600 delivers trays to the tray platform 200, and then the robotic arm 400 drives the suction cup assembly 410 to pick up the trays on the tray platform 200 and move them to the transfer box. Finally, the robotic arm 400 drives the suction cup assembly 410 to pick up the circuit boards on the board feeding mechanism 500 and move them to the trays in the transfer box. This process is repeated until the transfer box is full, thus completing the automated traying and boxing of the circuit boards. In another working mode of the automated packaging machine 10, the tray feeding mechanism 600 delivers trays to the tray platform 200. Then, the robotic arm 400 drives the suction cup assembly 410 to pick up the circuit boards and move them onto the trays on the tray platform 200. Finally, the lifting frame 810 of the stacking mechanism 800 moves the trays full of circuit boards onto the first conveyor belt 830. With the help of the stacking plate 820 and the stacking plate 840 of the stacking mechanism 800, the trays full of circuit boards can be stacked in sequence to complete the automated traying of circuit boards, thereby greatly improving the traying efficiency and playing a role in reducing costs and increasing efficiency.

[0025] In one embodiment, such as Figure 9As shown, the lifting frame 810 of the stacking mechanism 800 can slide on the side wall of the stacking cavity 110 via a slider and a slide rail, and is driven by a motor and a lead screw. The stacking plate 820 is driven by a cylinder to move vertically on the bottom of the stacking cavity 110, and the stacking plate 840 is driven by a cylinder to slide on the first conveyor guide rail. When the stacking mechanism 800 stacks trays full of circuit boards, the lifting frame 810 transfers the trays full of circuit boards on the tray platform 200 to the first end of the first conveyor belt 830. If a tray full of circuit boards is already placed on the second end of the first conveyor belt 830, the stacking plate 820 moves upward to lift the tray stack on the second end of the first conveyor belt 830. Then, the two stacking plates 840 move towards each other and support the tray stack. Subsequently, the stacking plate 820 moves downward, and the first conveyor belt... 830 conveys the tray filled with circuit boards at its first end to the second end, aligning the tray filled with circuit boards with the tray stack. Finally, the stacking plate 820 moves upward to attach the tray filled with circuit boards to the tray stack. The two stacking plates 840 move in opposite directions to release the support of the tray stack, and the stacking plate 820 resets. This enables the trays filled with circuit boards to be stacked on the first conveyor belt 830. The stacked trays filled with circuit boards can be transported to the next station by an external AGV trolley.

[0026] In one embodiment, such as Figure 4 As shown, the packing platform 300 includes two first roller conveyor plates 310 and two first limiting plates 320. The two first limiting plates 320 are spaced apart on the worktable 100, and the two first roller conveyor plates 310 are spaced apart on the worktable 100, with the two first roller conveyor plates 310 located between the two first limiting plates 320. Specifically, the two first limiting plates 320 and the two first roller conveyor plates 310 are respectively spaced apart on the worktable 100, and the two first roller conveyor plates 310 are located between the two first limiting plates 320. The first roller conveyor plates 310 are conveyor plates with multiple rollers that are rotatably arranged, which can effectively place the transfer boxes on the packing platform 300 and facilitate the transfer of full transfer boxes.

[0027] In one embodiment, such as Figure 4 As shown, a limiting roller 330 is slidably provided on the first limiting plate 320. The limiting roller 330 is used to move closer to or away from the transfer box. A cylinder is also provided on the first limiting plate 320. The cylinder is driven to move the limiting roller 330 closer to the transfer box and abut against the outer surface of the transfer box, so that the transfer box can be better placed on the packing platform 300 for packing.

[0028] In one embodiment, such as Figure 7 As shown, the tray feeding mechanism 600 includes: a first lifting plate 610 and two second conveyor belts 620. The two second conveyor belts 620 are spaced apart on the worktable 100 and are aligned with the placement plate 210. The first lifting plate 610 is raised and lowered on the worktable 100 and is located between the two second conveyor belts 620. Each second conveyor belt 620 is slidably provided with a material distribution plate 630. The two material distribution plates 630 move towards or away from each other. The movement direction of the first lifting plate 610 is perpendicular to the movement direction of the material distribution plate 630. Specifically, the second conveyor belt 620 includes: a second conveyor guide rail, a second belt, and two second pulleys. The two second pulleys are spaced apart on the second conveyor guide rail. The second belt rotates around the two second pulleys. A second pulley is driven to rotate by a motor, which enables the material tray to be conveyed on the second conveyor belt 620. The first lifting plate 610 is driven by a cylinder to move vertically on the worktable 100. The material distribution plate 630 is driven by a cylinder to slide on the second conveyor guide rail. When the feeding mechanism 600 delivers a tray to the tray platform 200, the first lifting plate 610 moves upward to lift the tray stack on the second conveyor belt 620. Then, the two separating plates 630 move towards each other and insert themselves between the first and second trays at the bottom of the tray stack. Finally, the first lifting plate 610 moves downward to separate the first tray at the bottom and move it onto the second conveyor belt 620. The tray is then conveyed forward by the second conveyor belt 620, thus enabling the tray to be delivered to the two placement plates 210 of the tray platform 200.

[0029] In one embodiment, such as Figure 3 As shown, each of the placement plates 210 has a placement slot 211, and the two placement slots 211 are arranged facing each other. Specifically, by having mutually facing placement slots 211 on the two placement plates 210, and aligning the placement slots 211 with the second conveyor belt 620, the trays conveyed forward by the tray feeding mechanism 600 can be stably placed on the two placement plates 210. When the trays filled with circuit boards on the tray platform 200 are stacked by the tray stacking mechanism 800, the lifting frame 810 lifts the trays filled with circuit boards, and then the two placement plates 210 move away from each other, so that the lifting frame 810 can drive the trays filled with circuit boards to descend through the lifting port 120 onto the two first conveyor belts 830. The placement plates 210 can slide on the worktable 100 via sliders and slide rails, and are driven by a motor and lead screw.

[0030] In one embodiment, such as Figure 9As shown, each of the first conveyor belts 830 is provided with a first guide baffle 850. Specifically, by providing two first guide baffles 850 at intervals on the two first conveyor rails, a guiding function can be achieved, which not only stably conveys the trays filled with circuit boards, but also facilitates the stacking plate 820 to stably lift and stack the trays filled with circuit boards sequentially, so that the trays filled with circuit boards can be stably stacked on the stacking mechanism 800.

[0031] In one embodiment, such as Figure 7 As shown, each of the second conveyor belts 620 is provided with a second guide baffle 640. Specifically, by providing two second guide baffles 640 at intervals on the two second conveyor rails, not only can the material trays be stably stacked on the tray feeding mechanism 600, but they can also serve as guides, which is beneficial for the first lifting plate 610 to stably lift the material tray stack for sequential material feeding.

[0032] In one embodiment, such as Figure 4 and Figure 8As shown, the automated packaging machine 10 further includes a box-loading mechanism 700, which includes a lifting platform 710, a lifting frame 720, and a second lifting plate 760. The lifting platform 710 is spaced apart from the worktable 100. The lifting frame 720 is lifted and lowered on the lifting platform 710. Multiple lifting plates 730 are spaced apart on the lifting frame 720. Two second limiting plates 740 are spaced apart on each lifting plate 730. Two second roller conveyor plates 750 are spaced apart between the two second limiting plates 740. The second roller conveyor plates 750 are movably aligned with the first roller conveyor plates 310. The second lifting plate 760 is lifted and lowered on the worktable 100 and is located between the two first roller conveyor plates 310. A transfer plate 761 is slidably disposed on the second lifting plate 760 and is slidably located within the lifting frame 720. Specifically, the lifting frame 720 can slide on the lifting platform 710 via a slider and slide rail, and is driven by a motor and lead screw. The second lifting plate 760 is driven by a cylinder to move vertically on the worktable 100. The transfer plate 761 is driven by a rodless cylinder to slide on the second lifting plate 760. The lifting frame 720 moves up and down on the lifting platform 710, allowing the second limiting plate 740 and the second roller conveyor plate 750 on each lifting plate 730 to align with the first limiting plate 320 and the first roller conveyor plate 310 of the packing platform 300, respectively. The second roller conveyor plate 750 is a conveyor plate with multiple rotating rollers. When the transfer box of the packing platform 300... After the tray containing the circuit boards is filled, the second lifting plate 760 moves upward to lift the filled transfer box. Then, the transfer plate 761 slides on the second lifting plate 760 and moves towards the lifting frame 720, which can transport the filled transfer box to the second roller conveyor plate 750 of the lifting plate 730. Subsequently, the transfer plate 761 is reset, and the lifting frame 720 continues to move up and down on the lifting platform 710, so that the lifting plate 730 on the lifting frame 720, which holds an empty transfer box, is aligned with the packing platform 300. Finally, the transfer plate 761 transports the empty transfer box to the packing platform 300 for packing, thus realizing the delivery of empty transfer boxes to the packing platform 300.

[0033] In one embodiment, such as Figure 4As shown, the transfer plate 761 is provided with a first limiting block 762 and a second limiting block 763 at intervals. The first limiting block 762 moves towards or away from the second limiting block 763. Specifically, the first limiting block 762 is driven by a cylinder to move towards or away from the second limiting block 763. When the second lifting plate 760 moves upward to lift a full transfer box or an empty transfer box is placed on the transfer plate 761, the first limiting block 762 moves towards the second limiting block 763, which can clamp and limit the full or empty transfer box. Thus, the transfer plate 761 can better transport the full transfer box to the lifting frame 720 or the empty transfer box to the packing platform 300.

[0034] In one embodiment, such as Figure 5 As shown, the suction cup assembly 410 includes a mounting frame 411 and a plurality of first vacuum suction cups 412. The mounting frame 411 is rotatably connected to the robotic arm 400, and each of the first vacuum suction cups 412 is spaced apart on the mounting frame 411. Specifically, each of the first vacuum suction cups 412 is mounted on the robotic arm 400 via the mounting frame 411. The first vacuum suction cups 412 are used to pick up and move the material tray and circuit board, thereby enabling automated movement of the material tray into the transfer box and the movement of the circuit board onto the material tray.

[0035] In one embodiment, such as Figure 5 As shown, a CCD camera 420 is provided on the mounting bracket 411. Specifically, by providing the CCD camera 420, visual positioning can be performed, so that the robotic arm 400 can accurately pick up the material tray and circuit board and load the circuit board onto the material tray through the suction cup assembly 410. It is worth noting that the method of visual positioning using the CCD camera 420 is a technology that is known to those skilled in the art and is achievable, and will not be described in detail in this embodiment.

[0036] In one embodiment, such as Figure 6 As shown, the board feeding mechanism 500 includes a conveying table 510 and a plurality of conveying rollers 520. The conveying table 510 is spaced apart from the worktable 100, and each of the conveying rollers 520 is uniformly rotatably mounted on the conveying table 510. Specifically, by uniformly rotatably mounting each of the conveying rollers 520 on the conveying table 510, the circuit board can be conveyed to the worktable 100 by roller conveying.

[0037] In one embodiment, such as Figure 6As shown, the automated packaging machine 10 further includes a clamping mechanism 530, which includes a clamping plate 531 and a clamping cylinder 532. The clamping plate 531 is disposed on the worktable 100, and the clamping cylinder 532 is slidably disposed on the clamping plate 531, and the clamping cylinder 532 is movably aligned with the conveying table 510. Specifically, the clamping cylinder 532 can slide on the clamping plate 531 via a slider and a slide rail, and is driven by a motor and a lead screw. When the board feeding mechanism 500 conveys the circuit board to be aligned with the clamping cylinder 532, the clamping cylinder 532 can clamp the circuit board, and then the circuit board can be driven to rise by sliding on the clamping plate 531 via the clamping cylinder 532. By raising the circuit board to a certain height, it is beneficial for the robotic arm 400 to pick up and move the circuit board through its suction cup assembly 410.

[0038] In one embodiment, such as Figure 7 and Figure 9 As shown, two first conveyor belts 830 are slidably disposed on the bottom of the stacking cavity 110, and the two first conveyor belts 830 move towards or away from each other. Two second conveyor belts 620 are slidably disposed on the worktable 100, and the two second conveyor belts 620 move towards or away from each other. Specifically, the first conveyor belts 830 can slide on the bottom of the stacking cavity 110 via sliders and slide rails, and are driven by a motor and a lead screw. Correspondingly, the second conveyor belts 620 can slide on the worktable 100 via sliders and slide rails, and are driven by a motor and a lead screw. The spacing between the two first conveyor belts 830 and the two second conveyor belts 620 can be adjusted. With the help of two placement plates 210, they can move towards or away from each other on the worktable 100, which can accommodate the feeding, placement, and stacking of trays of different specifications, thereby enabling the packaging of circuit boards of different specifications.

[0039] In one embodiment, the tray feeding mechanism 600 further includes a plurality of second vacuum suction cups, each of which is spaced apart on the first lifting plate 610. Specifically, by providing the second vacuum suction cups, automatic tray separation of multi-layer trays can be better achieved, resulting in a better separation effect. Thus, when the tray feeding mechanism 600 conveys trays to the tray platform 200, the first lifting plate 610 moves upward to lift the tray pile on the second conveyor belt 620. Then, the two separating plates 630 move towards each other and insert themselves between the first and second trays at the bottom of the tray pile. Finally, the second vacuum suction cups adsorb the first tray at the bottom. At this time, the two separating plates 630 support the remaining trays in the tray pile. By moving the first lifting plate 610 downward, the first tray at the bottom can be better separated and moved onto the second conveyor belt 620. After the second vacuum suction cups release their adsorption, the second conveyor belt 620 can transport the separated trays forward to the tray platform 200.

[0040] Compared with the prior art, the present invention has at least the following advantages: This invention provides an automated packaging machine that uses a tray platform and a boxing platform spaced apart on a worktable. The boxing platform holds transit boxes, a tray feeding mechanism delivers trays to the tray platform, and a board feeding mechanism delivers circuit boards to the worktable. A robotic arm drives a suction cup assembly to pick up trays from the tray platform and place them into the transit boxes. Then, it picks up circuit boards and places them onto trays within the transit boxes until the transit boxes are full, thus automating the traying and boxing of circuit boards. Simultaneously, the robotic arm can also drive the suction cup assembly to pick up circuit boards and place them onto trays on the tray platform. Trays full of circuit boards can be moved to a first conveyor belt via a stacking mechanism's lifting frame. With the help of stacking plates and material stacking plates, trays full of circuit boards can be stacked sequentially, achieving another method of automated traying of circuit boards, thereby greatly improving traying efficiency and reducing costs while increasing efficiency.
