[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0030] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0031] It should be supplemented that the X direction, Y direction and Z direction involved in this embodiment are directions perpendicular to the horizontal and vertical planes.

[0032] like Figure 1 and Figure 2 As shown, the pallet automatic packing equipment of the present practical design includes adjacently arranged pallet conveyor line 1 and a pallet 2 for placing packaging boxes; a main frame 10 is also erected along the pallet conveyor line 1 and above the pallet 2; a pallet lifting plate 3 is provided on the main frame 10, as well as an X-axis moving component 4, a Y-axis moving component 5 and a Z-axis moving component 6 which are sequentially connected to the pallet lifting plate 3; a pallet extraction clamp 7 is installed on the pallet lifting plate 3; the X-axis moving component 4, the Y-axis moving component 5 and the Z-axis moving component 6 are used to drive the pallet extraction clamp 7 to move along the X-axis, the Y-axis and the Z-axis so that the pallets on the pallet conveyor line 1 are stacked in turn into packaging boxes on the pallet 2.

[0033] First, the equipment realizes continuous conveying of pallets and placement of packaging boxes respectively through adjacently arranged pallet conveying lines 1 and pallets 2. The main frame 10 above provides a stable structural support for the entire operation.

[0034] On the main frame 10, the function of the pallet lifting plate 3 is to grab and lift the pallet through the pallet extraction clamp 7. The pallet extraction clamp 7 is usually designed to be a structure that can firmly grasp the bottom of the pallet, such as using a pneumatic suction cup or other types of clamps.

[0035] Once the pallet is grabbed by the clamp 7 on the lifting plate 3, the device can realize accurate positioning and movement of the pallet through the X-axis moving assembly 4, the Y-axis moving assembly 5 and the Z-axis moving assembly 6. These moving assemblies usually include mechanical structures such as motor-driven linear guides, gear racks, and corresponding control systems to ensure that the pallet can be accurately and smoothly moved into the packaging box above the pallet 2.

[0036] As an implementation method, Figure 3 As shown, the X-direction moving component 4 includes:

[0037] A linear guide rail 4.1 mounted on the main frame 10;

[0038] A slide 4.2 slidably engaged with the linear guide 4.1;

[0039] A rack 4.3 arranged along one side of the linear guide rail 4.1;

[0040] A gear 4.4 mounted on the slide 4.2 and meshing with the rack 4.3;

[0041] A motor 4.5 for driving the gear 4.4.

[0042] When the motor 4.5 is started, it drives the slide 4.2 to move horizontally along the linear guide rail 4.1 through the meshing relationship between the gear 4.4 and the rack 4.3. This structure ensures that the pallet lifting plate 3 and the pallet extraction fixture 7 thereon can move smoothly and accurately along the X-axis direction, thereby realizing accurate positioning and movement of the pallet in the horizontal direction.

[0043] The working principle of the Y-direction moving assembly 5 and the Z-direction moving assembly 6 is similar to that of the X-direction moving assembly 4. The Y-direction moving assembly 5 controls the movement of the pallet lifting plate 3 in the Y-axis direction perpendicular to the conveyor line body 1, while the Z-direction moving assembly 6 is responsible for the vertical lifting and lowering of the pallet lifting plate 3 in the Z-axis direction. These two groups of moving assemblies also use a combination of linear guides, slides, racks, gears and motors to achieve precise positioning and movement of the pallet in the Y-axis and Z-axis directions through similar mechanical transmission and control systems. Since their structural principles are consistent with those of the X-direction moving assembly 4, they will not be described in detail.

[0044] As an implementation method, Figure 4 As shown, the pallet extraction fixture 7 includes a plurality of pneumatic suction cups 7.1 evenly arranged below the pallet lifting plate 3.

[0045] The pneumatic suction cup 7.1 is driven by an air pipe connected to an air source (such as an air compressor), which is not supplemented here.

[0046] When the air source provides compressed air, the air flows into the pneumatic suction cup through the air pipe, increasing the air pressure inside the suction cup. At the same time, due to the large contact area between the suction cup and the tray, and the suction cup material has a certain sealing property, the air between the suction cup and the tray is quickly discharged, forming a negative pressure.

[0047] When the tray needs to be released, the air source is controlled to reduce or eliminate the air pressure inside the pneumatic suction cup 7.1, and the adsorption force between the suction cup and the tray also disappears. At this time, the tray can be smoothly dropped from the pneumatic suction cup.

[0048] As an implementation manner, a sliding rod 8 is further provided on the tray lifting plate 3, and a contact block 8.1 for contacting the suction cup is provided at the bottom end of the sliding rod 8.

[0049] Specifically, the tray lifting plate 3 is also provided with a photoelectric sensor 8 . 2 for detecting the top position of the sliding rod 8 .

[0050] The photoelectric sensor 8.2 may be a slot-type photoelectric sensor, such as EE-SX676 manufactured by OMRON.

[0051] The sliding rod 8 is sleeved with a spring 8.3 for supporting the contact block 8.1 and the tray lifting plate 3. The top of the sliding rod 8 is also equipped with a limit nut 8.4, which is used to limit the travel of the sliding rod 8 to prevent it from excessively rising or falling, thereby protecting the safety of the system. The tray lifting plate 3 is also provided with a linear bearing that cooperates with the sliding rod 8 to reduce the friction and resistance of the sliding rod 8 during movement, making its movement smoother and more stable.

[0052] The contact block 8.1 is used to contact with the pneumatic suction cup 7.1. When the pneumatic suction cup 7.1 absorbs the tray and lifts it, the contact block 8.1 will rise with the rise of the tray, thereby driving the sliding rod 8 to slide in the linear bearing.

[0053] A photoelectric sensor 8.2 is also provided on the pallet lifting plate 3 to detect the position of the top end of the sliding rod 8. When the sliding rod 8 rises with the contact block 8.1, the photoelectric sensor 8.2 receives a signal and determines whether the pallet has been successfully grabbed. This detection method helps to ensure the reliability and accuracy of the system operation.

[0054] The sliding rod 8 is provided with a spring 8.3 on its outer sleeve, and the spring 8.3 is located between the contact block 8.1 and the tray lifting plate 3. When the pneumatic suction cup 7.1 releases the tray and descends, the spring 8.3 provides a restoring force to push the contact block 8.1 and the sliding rod 8 back to the initial position, ensuring that the system is in a ready state, waiting for the next tray grabbing operation.

[0055] As an embodiment, the pallet conveyor line 1 is provided with two opposite positioning plates 9 along the conveying direction of the pallet, and the front section of the positioning plates 9 is open, so as to ensure that the pallet can maintain the correct position and direction during the conveying process and prevent the pallet from being offset or rotated.

[0056] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.
