Description

Technical Field

[0001] This utility model relates to the field of metal block transfer pallet positioning technology, specifically to a positioning device for AGV trolleys to transfer metal block loading pallets. Background Technology

[0002] Metal pallets are widely used in logistics, warehousing, and manufacturing, serving as a crucial medium for goods storage and handling. In automated warehousing systems, pallets need to precisely interface with equipment such as stacker cranes and conveyor lines to enable rapid storage, retrieval, and transfer of goods. Therefore, the accuracy of pallet positioning and support directly impacts cargo handling efficiency and equipment stability.

[0003] Existing technology discloses a pallet positioning device for AGVs (CN201521106565.4), which uses six sets of cylinders in four directions (left, right, front, and back) to drive the sliding plate to achieve clamping and positioning of the middle pallet. Its structure is relatively complex, the cylinder driving process affects the positioning accuracy, and the entire device occupies a large space. To solve the problem of friction at the bottom of the moving pallet, this technical solution changes sliding friction to rolling friction by installing bullseye bearings on the device surface.

[0004] Existing technology also discloses a mother-daughter pallet positioning device (CN202120614740.X), which solves the technical problem of achieving neat stacking of daughter pallets based on a mother pallet. It employs a combination of a front limiting rod and side limiting plates to keep the mother pallet relatively stationary on the roller conveyor. Then, a mechanical forklift places a daughter pallet onto the mother pallet. At this time, the side limiting cylinders on both sides of the roller conveyor drive the side limiting plates, pushing the mother and daughter pallets inward from both sides, thus positioning them neatly.

[0028] To provide a detailed explanation of the technical solution disclosed in this utility model, further details are provided below in conjunction with the accompanying drawings.

[0029] A positioning device for AGV (Automated Guided Vehicle) trolleys transporting metal block loading pallets includes a left support 1 and a right support 6, both having the same height and length. Four sets of inclined rolling modules 7 are installed between the left support 1 and the right support 6 to achieve optimal structure. Furthermore, to accommodate different metal pallets 9, a flexible design can be adopted, increasing the number of rolling modules 7 as needed.

[0030] refer to Figure 1 A baffle plate with an upward protrusion is provided at the rear end of the left bracket 1 to provide obstruction. A mounting base for cylinder installation is located in the middle, which can be designed as a reinforcing plate. It has a through hole in the center and fixing holes around the perimeter. The second cylinder 12 is mounted on the fixing holes with bolts. The output shaft passes through the through hole to achieve forward and backward extension. Bullseye ball bearings 11 are installed on the output shaft. Four slots are also reserved on the left bracket 1 for installing the rolling module 7. The rolling module 7 is as follows... Figure 4 As shown, it includes a fixed shaft 701 and a rolling bushing 702. The rolling bushing 702 is fixed to the middle of the fixed shaft 701 by a snap ring 703. Bolt holes are provided at both ends of the fixed shaft 701 for mounting the rolling module 7 on the bracket.

[0031] refer to Figure 3 The right bracket 6 has a raised baffle plate at its rear end and a push tube 3 at its front end; see its structure for details. Figure 4 Below the push tube 3, a fisheye screw 4 is connected by a mounting bracket. The other end of the fisheye screw 4 is connected to the first cylinder 5, which is fixed below the right bracket 6.

[0032] According to the above structure, its working principle is as follows: First, the left support 1 and the right support 6 are fixed to the ground with anchor bolts, and then the components are installed sequentially as described above. The metal block 10 is placed on the metal tray 9 and loaded into the positioning device of this utility model by the AGV trolley 2. Since the rolling module 7 on the left support 1 and the right support 6 is not vertically installed, a buffer space is formed between this device and the AGV trolley 2, which facilitates the transfer of the tray on the AGV trolley 2 to this positioning device. Then, the second cylinder 12 installed on the left support 1 drives the bullseye ball 11 to move forward, pushing the metal tray 9. It is blocked by the two external screw bearings 8 on the right support 6. At this time, the tray is parallel to the left support 1. During this process, the bullseye ball 11 reduces the friction between the second cylinder 12 and the metal tray 9, and can easily move into place. After the AGV trolley 2 is positioned, the first cylinder 5 is activated, which pulls the fisheye screw 4, causing the push tube 3 to move along the right support 6. At this time, due to the rolling module 7 structure between the left support 1 and the right support 6, and the action of the bullseye ball bearing 11 on the cylinder and the external screw bearing 8 on the right support 6, the metal tray 9 is prone to sliding. As the first cylinder 5 is pulled, the metal tray 9 is accurately positioned by the action of the protruding baffle on the moving push tube 3 and the rear blocking plates of the left support 1 and the right support 6. This allows for the setting of the gripping center position of the robot arm in subsequent operations, facilitating convenient and quick gripping operations.
