[0029] like Figure 1 , Figure 2 As shown, this utility model provides a conveying device, including a body 1. The body 1 contains a first lifting device 2, a second lifting device 3, an upper conveying mechanism 4, a lower conveying mechanism 5, a first transfer mechanism 6, and a second transfer mechanism 7. The body 1 serves as the supporting structure for the entire conveying device, providing a platform for the installation and operation of other devices or mechanisms.

[0030] The first lifting device 2 and the second lifting device 3 are disposed opposite each other on both sides of the machine body 1, and are used to transport the pallet 10 up and down along the Z-axis. The upper conveying mechanism 4 and the lower conveying mechanism 5 are both located between the first lifting device 2 and the second lifting device 3, and are used to transport the pallet 10 between the first lifting device 2 and the second lifting device 3 along the X-axis, with the upper conveying mechanism 4 located above the lower conveying mechanism 5. The first pallet transfer mechanism 6 is located between the upper conveying mechanism 4 and the first lifting device 2, and is used to transfer the pallet 10 between the first lifting device 2 and the upper conveying mechanism 4; the second pallet transfer mechanism 7 is located between the upper conveying mechanism 4 and the second lifting device 3, and is used to transfer the pallet 10 between the second lifting device 3 and the upper conveying mechanism 4.

[0031] In this utility model, the pallet 10 can be placed at any of the following positions: the first lifting device 2, the second lifting device 3, the upper conveying mechanism 4, and the lower conveying mechanism 5, as the starting position for conveying, thereby improving the convenience of loading and unloading. Furthermore, a circular conveying chain is formed between the first lifting device 2, the lower conveying mechanism 5, the second lifting device 3, the second pallet transfer mechanism 7, the upper conveying mechanism 4, the first pallet transfer mechanism 6, and the first lifting device 2, thereby improving the flexibility, convenience, and efficiency of conveying.

[0032] In one embodiment, such as Figures 1-3As shown, a positioning mechanism 8 is also provided on the upper side of the first lifting device 2 and the second lifting device 3. The positioning mechanism 8 includes two sets of positioning plates 81 arranged opposite each other along the X-axis direction and a positioning cylinder 82 that controls the positioning plates 81 to move along the Y-axis direction. The positioning plates 81 include a horizontal plate 811 and a vertical plate 812 arranged vertically. The horizontal plate 811 is located at the top of the vertical plate 812, and the vertical plate 812 is parallel to the XZ plane.

[0033] In this embodiment, the two sets of positioning plates 81 are respectively located on both sides of the first lifting device 2 or the second lifting device 3. The positioning cylinder 82 can be installed on the machine body 1. The positioning plate 81 is connected to the piston rod of the positioning cylinder 82. Under the action of the positioning cylinder 82, the positioning plate 81 reciprocates along the Y-axis. When the pallet 10 is transported between the two sets of positioning plates 81, both sets of positioning plates 81 move towards each other to abut and clamp the pallet 10, thereby adjusting the position of the pallet 10 and ensuring the stability and accuracy of the pallet 10 during the transport process. This facilitates the transport of the pallet 10 along the upper conveying mechanism 4 or the first lifting device 2 and the second lifting device 3. When the first pallet transfer mechanism 6 and the second pallet transfer mechanism 7 place the pallet 10, the horizontal plate 811 of the positioning plate 81 can also limit the placement of the pallet 10, facilitating its placement.

[0034] In one embodiment, such as Figure 4 , Figure 5 As shown, both the upper conveying mechanism 4 and the lower conveying mechanism 5 include two sets of belt conveyor assemblies 41 arranged at intervals and in parallel, and a conveyor motor 42 that is drivenly connected to the belt conveyor assemblies 41. This facilitates stable support and conveying of the pallet 10.

[0035] In one embodiment, such as Figure 4 As shown, the belt conveyor assembly 41 includes a first synchronous belt 411 and a first driving pulley 412 and a first driven pulley 413 rotatably connected to the machine body 1. The first synchronous belt 411 surrounds the first driving pulley 412 and the first driven pulley 413. The first driving pulleys 412 of the two sets of belt conveyor assemblies 41 are connected by a transmission shaft 43. The transmission shaft 43 is driven by a conveyor motor 42. Specifically, pulleys can be set on the output shaft of the transmission shaft 43 and the conveyor motor 42, and a third synchronous belt 44 can be set between the pulleys to realize the transmission connection between the conveyor motor 42 and the transmission shaft 43. When the conveyor motor 42 runs, it drives the transmission shaft 43 to rotate. The rotation of the transmission shaft 43 drives the two first driving pulleys 412 at both ends to rotate, thereby causing the first synchronous belt 411 to rotate, so as to achieve stable conveying of the pallet 10.

[0036] In one embodiment, such as Figure 5As shown, the belt conveyor assembly 41 also includes a tensioning wheel 414 rotatably connected to the machine body 1. The tensioning wheel 414 is disposed on the outer ring of the first synchronous belt 411 and abuts against it to tension the first synchronous belt 411.

[0037] In one embodiment, such as Figure 5 As shown, there are two first driven pulleys 413, which are horizontally arranged and located at the starting and ending ends of the belt conveyor assembly 41, respectively. The first driving pulley 412 is located in the middle of the belt conveyor assembly 41, forming a triangle with the two first driven pulleys 413. There are two tensioning pulleys 414, both located on the outer ring of the first synchronous belt 411 and on both sides of the first driven pulleys 413, to tension the first synchronous belt 411. This achieves stable conveying of the pallet 10.

[0038] In one embodiment, such as Figure 4 As shown, multiple blocking mechanisms 9 are arranged at intervals between the two sets of belt conveyor assemblies 41 along their conveying direction. The blocking mechanism 9 includes a stop bar 91 and a stop bar cylinder 92 that controls the raising and lowering of the stop bar 91, so as to block the operation of the tray 10 on the belt conveyor assemblies 41 in sections.

[0039] In one embodiment, such as Figure 2 , Figure 3 As shown, both the first lifting device 2 and the second lifting device 3 include a lifting seat 21 for carrying the pallet 10 and a lifting mechanism 22 for controlling the lifting seat 21. The lifting seat 21 can be lifted between the two sets of first synchronous belt 411 mechanisms of the lower conveying mechanism 5, so that the pallet 10 carried on the lifting seat 21 can be placed directly on the two sets of belt conveying components 41 of the lower conveying mechanism 5 without the need to add other mechanisms for displacement.

[0040] In one embodiment, the lifting mechanism 22 includes a lifting motor 221, two sets of Z-axis slide rails 222, a second driving wheel 223, a second driven wheel 224, and a second synchronous belt 225. The two sets of Z-axis slide rails 222 extend along the vertical direction of the machine body 1 and are spaced apart on the machine body 1. The second driving wheel 223 and the second driven wheel 224 are rotatably connected to the machine body 1 and are spaced apart along the vertical direction of the machine body 1. The output shaft of the lifting motor 221 is connected to the first driving wheel 412. The second driving wheel 223 and the second driven wheel 224 are connected through the second synchronous belt 225. The lifting seat 21 is connected to the second synchronous belt 225. When the lifting motor 221 operates, it drives the second driving wheel 223 to rotate. The rotation of the second driving wheel 223 causes the second synchronous belt 225 to rotate, thereby driving the lifting seat 21 to move up and down along the Z-axis to achieve stable lifting of the lifting seat 21.

[0041] In one embodiment, both the first tray transfer mechanism 6 and the second tray transfer mechanism 7 include a support base 61, multiple suction nozzles 62 disposed at the bottom of the support base 61, a lifting cylinder 63 for controlling the lifting of the support base 61, and a moving mechanism 64 for controlling the movement of the support base 61 and the lifting cylinder 63 along the X-axis direction. Specifically, the moving mechanism 64 includes two sets of X-axis slide rails 65 disposed on the machine body 1 and extending along the X-axis direction, a sliding seat 66 for fixing the lifting cylinder 63, and a lead screw motor or rodless cylinder 67 for controlling the movement of the sliding seat 66. The two sets of X-axis slide rails 65 are respectively located outside the two sets of belt conveyor assemblies 41 of the upper conveying mechanism 4. The sliding seat 66 is slidably connected to the X-axis slide rails 65 and connected to the slide seat of the lead screw motor or rodless cylinder. Under the action of the moving mechanism 64, the sliding seat 66 moves stably. In this embodiment, the tray 10 is adsorbed by the suction nozzles 62, and the horizontal and vertical movement of the tray is achieved by using the lifting cylinder 63 and the moving mechanism 64.

[0042] In one embodiment, baffles 11 are provided on both sides of the first lifting device 2, the second lifting device 3, and the lower conveying mechanism 5 to limit the position of the pallet 10 and prevent the pallet 10 from accidentally slipping off.

[0043] Those skilled in the art should understand that the specific embodiments described above are merely examples and not limitations. Various modifications, combinations, partial combinations, and substitutions can be made to the embodiments of this utility model according to design requirements and other factors, as long as they are within the scope of the appended claims or their equivalents, and thus fall within the scope of the rights to be protected by this utility model.
