[0031] The first pallet transfer system 100 includes a first pallet loading device 110, a first pallet unloading device 120, a first pallet transfer robot 130, and a barcode scanning module 140. The first pallet loading device 110 is used to receive and supply a first pallet fully loaded with circuit boards, the first pallet unloading device 120 is used to receive and output an empty first pallet, the first pallet transfer robot 130 is used to transfer the first pallet from the first pallet loading device 120 to the first pallet unloading device 120, and the barcode scanning module 140 is used to scan the circuit boards on the first pallet.

[0032] The second pallet transfer system 200 includes a second pallet loading device 210, a pallet positioning mechanism 220, a second pallet transfer robot 230, and a second pallet unloading device 240. The second pallet loading device 210 is used to receive and supply empty second pallets, the second pallet transfer robot 230 is used to transfer the second pallets from the second pallet loading device 210 to the pallet positioning mechanism 220, and the second pallet unloading device 240 is used to stack or directly output second pallets fully loaded with circuit boards.

[0033] In this invention, a pallet transfer robot is used to transfer pallets between different workstations, and it is compatible with pallets without skirts, thereby improving the versatility of the equipment. The circuit board transfer robot 300 is configured to move between the first pallet unloading device 120 and the pallet positioning mechanism 220, for transferring circuit boards located in the first pallet of the first pallet unloading device 120 to the second pallet located in the pallet positioning mechanism 220.

[0034] Preferably, the second pallet transfer system 200 and the first pallet transfer system 100 are arranged parallel to each other in the X direction (i.e., both are arranged along the X direction as a whole); wherein, the second pallet loading device 210 and the first pallet loading device 110 are arranged side by side in the Y direction, and the pallet positioning mechanism 220 and the first pallet unloading device 120 are arranged side by side in the Y direction, so as to simplify the overall layout of the equipment and the space occupied, and reduce the travel required by the circuit board transfer robot 300 when changing circuit boards, thereby further improving the pallet changing efficiency.

[0035] Furthermore, both the first pallet transfer system 100 and the second pallet transfer system 200 are preferably configured to accommodate pallets of different sizes. For example, the width of their loading / unloading devices and clamping / conveying mechanisms can be adjusted to match the usage requirements of pallets of different sizes.

[0036] In this embodiment, the first pallet loading device 110 and the second pallet loading device 210 may have the same structure and pallet loading steps; the second pallet loading device 210 will be used as an example for illustration. Figure 4 As shown, the first pallet loading device 210 includes a pallet loading assembly 11 and a pallet loading clamping mechanism 12; wherein, as Figure 6As shown, the pallet loading assembly 11 includes a pallet loading conveyor 101 and a pallet height adjustment mechanism. The pallet loading conveyor 101 is used to input stacked pallets, and the pallet height adjustment mechanism is used to adjust the stacked pallets to a height where the top pallet can be clamped by the pallet loading clamping mechanism 12.

Specifically, the pallet loading conveyor 101 can be a conveyor belt, which can dock with an AGV (Automated Guided Vehicle) to transport pallets for inputting stacked pallets.

[0037] In this embodiment, the pallet height adjustment mechanism of the first pallet loading device 110 and the second pallet loading device 210 includes a lifting platform 1021 and a pallet lifting mechanism 1022. The lifting platform 1021 is driven by a cylinder to lift and lower, receiving and raising stacked pallets from the pallet loading conveyor 101 to a preset height. The pallet lifting mechanism 1022 further lifts the pallets on the lifting platform 1021 so that the topmost pallet can be clamped by the pallet loading clamping mechanism 12.

[0038] Specifically, the pallet lifting mechanism 1022 includes a lifting body 1022a and a lifting module 1022b that drives the lifting body 1022a to lift.

After the lifting platform 1021 raises the stacked loading pallets to a preset height, the lifting body 1022a / lateral support part 1022c extends under the loading pallets to support the stacked loading pallets. Then, the lifting module 1022b drives the lifting body 1022a to gradually rise until the uppermost pallet can be clamped by the pallet loading clamping mechanism 12.

[0039] The first pallet unloading device 120 has the same structure as the first pallet loading device 110 / second pallet loading device 210, the difference being that the first pallet loading device 110 / second pallet loading device 210 is used for pallet loading, while the first pallet unloading device 120 is used for pallet unloading; their operating procedures are different. The same applies to... Figure 4 and Figure 6The first pallet unloading device 120 is provided with a pallet unloading assembly 121 and a pallet unloading clamping mechanism 122. The pallet unloading assembly 121 includes, for example, a pallet unloading conveying mechanism 1211 with a conveyor belt and a pallet height adjustment mechanism 1212. The pallet height adjustment mechanism is used to receive empty first pallets from the pallet unloading clamping mechanism 122 for stacking and adjusting the stacking height. The pallet unloading conveying mechanism 1211 is used to output empty first pallets, for example, to transport the empty first pallets to an AGV material cart for automatic unloading.

[0040] like Figure 7 As shown in the embodiment, the pallet loading clamping mechanism 12, the pallet unloading clamping mechanism 122, and the pallet positioning mechanism 220 can have the same structure, all including clamping components for clamping the two opposite sides of the pallet from above and below. The clamping components are disposed on two oppositely arranged clamping sidewalls. Preferably, the distance between the two oppositely arranged clamping sidewalls is adjustable to accommodate pallets of different sizes. The specific structure of the clamping components can be referred to in the prior art, and will not be described in detail here.

[0041] In this embodiment, the first pallet transplanting robot 130 and the second pallet transplanting robot 230 may have the same structure; the first pallet transplanting robot 130 will be used as an example for illustration. Figure 8 As shown, the first pallet transfer robot 130 includes a first X-axis translation module 131, a first Z-axis lifting module 132, and a first suction cup assembly 133 connected in sequence. The first suction cup assembly 133 can translate along the X-axis under the drive of the first X-axis translation module 131, and can be lifted and lowered under the drive of the first Z-axis lifting module 132 to realize the transfer of the first pallet. The first suction cup assembly 133 preferably adopts a quick-change installation structure.

[0042] A barcode scanning module 140 is installed on the first pallet transfer robot 130 and is used to scan the circuit boards on the first pallet. Specifically, for example... Figure 8 As shown, the barcode scanning module 140 includes a first Y-axis translation module 141 connected to a first X-axis translation module 131 and a barcode scanner 142 mounted on the first Y-axis translation module 141. The first X-axis translation module 131 and the first Y-axis translation module 141 can drive the barcode scanner 142 to move along the X and Y directions to scan the circuit boards stored in the first tray. During operation, the barcode scanner 142 first scans the circuit boards on the first tray supplied by the first tray loading device 110 to achieve traceability management. Then, the first tray transfer robot 130 transfers the first tray from the first tray loading device 110 to the first tray unloading device 120.

[0043] As a variation of the embodiment, the barcode scanning module 140 can also be set relatively independently from the first pallet transfer robot 130, that is, the barcode scanning module 140 can be equipped with an independent X-axis translation module.

[0044] The circuit board transfer robot 300 includes a circuit board suction cup assembly 310 capable of three-dimensional movement and horizontal rotation. The circuit board suction cup assembly 310 is equipped with multiple independently lifting circuit board suction cups 311. For example... Figure 9 As shown, the circuit board transfer robot 300 in this embodiment includes an X-axis translation module 320, a Y-axis translation module 330, and a Z-axis lifting module 340 connected in sequence. A circuit board suction cup assembly 310 is mounted on the Z-axis lifting module 340, enabling movement in the X, Y, and Z directions. Preferably, the Z-axis lifting module 340 is a ZR drive module equipped with a rotation drive module, capable of driving the circuit board suction cup assembly 310 to rotate horizontally. The circuit board suction cup assembly 310 preferably adopts a quick-change mounting structure.

[0045] Furthermore, the Z-axis lifting module 340 of the circuit board transfer robot 300 can be equipped with a detection camera 350. Before the circuit board transfer robot 300 picks up the circuit board from the first tray, the detection camera 350 first performs position detection on the circuit board to ensure that it can be accurately placed in the set position in the second tray, thereby achieving error prevention and ensuring high-quality requirements. As a variation of the embodiment, the detection camera 350 can also be set between the first tray unloading device 120 and the tray positioning mechanism 220. After the circuit board transfer robot 300 picks up the circuit board, it moves above the detection camera to perform circuit board position detection.

[0046] like Figure 4 and Figure 5 As shown, the second pallet unloading device 240 includes a second pallet transfer mechanism 241 and a second pallet stacking mechanism 242. The second pallet transfer mechanism 241 is located below the tray positioning mechanism 220 and is used to transport the second pallet fully loaded with circuit boards from the tray positioning mechanism 220 to the second pallet stacking mechanism 242 for storage. The specific structure of the second pallet stacking mechanism 242 can be referred to the prior art, and will not be described in detail here.

[0047] In the embodiments, such as Figure 10 As shown, the second pallet transfer mechanism 241 includes a second X-axis translation module 2411, a second Z-axis lifting module 2412, and a rotation module 2413 connected in sequence. The rotation module 2413 is provided with a support suction cup 2414 for supporting the second pallet, and the support suction cup 2414 can rotate horizontally under the drive of the rotation module 2413. Further, the second pallet transfer mechanism 241 also includes a second Y-axis translation module 2415, and the second X-axis translation module 2411 is mounted on the second Y-axis translation module 2415.

[0048] As a variation of the embodiment, the second pallet unloading device 240 can also directly output the second pallet fully loaded with circuit boards to the subsequent workstation. For example, the second pallet transfer mechanism 241 transfers the second pallet to the conveyor belt of the docking workstation, and the conveyor belt directly outputs the fully loaded second pallet to the subsequent workstation.

[0049] In summary, the circuit board barcode scanning and tray changing machine of this embodiment has an automatic barcode scanning and tray changing function, which is particularly suitable for, but not limited to, tray changing operations of flexible circuit boards. The tray changing is accurate and reliable, and the barcode scanning is complete. The tray transfer is performed by a transfer robot, which can achieve compatibility with trays with and without skirts, and has high versatility. When the circuit board transfer robot performs circuit board tray changing, it takes pictures with the detection camera, which has precise positioning, accurate material handling and tray placement, and realizes multiple material handling logics. It has high efficiency, with a CT of up to 1 second / PCS. The detection camera can take pictures for re-inspection to ensure that the circuit boards have a 100% pass rate after tray changing.

[0050] Although the present invention has been described above through embodiments, it should be understood that any equivalent changes made by those skilled in the art without departing from the scope of the present invention should be covered by the protection scope of the present invention.
