Example Embodiment

[0032] Example one

[0033] image 3 It is a schematic structural diagram of a high-level forklift provided by Embodiment 1 of the present invention. It includes a fork 1, an image collector 2, a distance sensor 3, and a processing module 4. The processing control module 4 is respectively connected to the fork 1, the image collector 2, The distance sensor 3 is electrically connected; further, the processing control module 4 is connected to the fork 1 through a drive mechanism, and controls the movement of the fork 1 through the drive mechanism. The drive mechanism includes a drive motor, gears and other components. It should be noted here that the high-level forklift in other embodiments of the present invention (for example Figure 4 with Figure 5a The drive mechanism in) has the same composition and function as the drive mechanism in this embodiment.

[0034] The fork 1 includes a first fork 11 and a second fork 12, which are used to carry a storage container to be placed;

[0042] Example two

[0043] Figure 4 It is a schematic structural diagram of a high-level forklift provided by this embodiment. This embodiment is optimized on the basis of the above-mentioned embodiment. The processing control module 4 includes:

[0044] The target position adjustment unit is used to control the fork to move to the target position by moving left and right or up and down according to the position of the collected positioning mark in the image taken by the image collector, where the positioning mark corresponds to the target position The projected image of is located in the preset standard position in the image taken by the image collector.

[0045] The preset standard position is exemplarily the center position of the image captured by the image collector. Due to the level of ground level or the control accuracy of the high-mounted forklift itself, when the fork lifts the storage container to the same height as the target layer of the target storage container, the ...

[0050] Example three

[0051] Figure 5a It is a schematic structural diagram of a high-level forklift provided by this embodiment. This embodiment is optimized on the basis of the above-mentioned embodiment. The processing control module 4 includes:

[0052] The judging unit is used for judging the collected positioning mark according to the position of the collected positioning mark in the image taken by the image collector before the vertical moving unit moves the fork vertically upward from the target position by a preset distance Whether the angular deviation in the horizontal direction is greater than a preset angle threshold.

[0053] Due to the influence of the level of the warehouse floor, the forks will have a certain tilt, so it is necessary to determine whether the current tilt of the forks will affect the return of the storage container. Specifically, it can be determined by judging whether the angular deviation of the collected positioning mark in the horizontal direct...

Abstract

The embodiment of the invention discloses a High-lift forklift, a calibration method for returning a storage container and a storage medium. The high-lift forklift comprises a fork. The fork is provided with an image collector and a distance sensor. The image collector is used for collecting locating mark on a target inventory container to obtain image data capable of representing the position relationship between the projected images of the fork and the locating mark on a designated plane. The distance sensor is used for measuring the distance between the fork and the target inventory container and obtaining the distance data. The calibration method for returning the storage container comprises the steps that after the fork lifts the storage container to be placed to the same height of atarget layer of the target inventory container, and according to the image data, the position relationship between the projected images of the fork and the locating mark on the designated plane is adjusted; according to the distance data, the distance between the fork and the target inventory container is adjusted. In this way, through adjustment of the position of the fork relative to the inventory container, the storage container is accurately returned, and the returning efficiency of the storage container is improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of unmanned forklift equipment, and in particular to a high-position forklift, a calibration method for returning a storage container, and a storage medium. Background technique [0002] With the rapid development of my country's logistics industry, safe and efficient operating procedures have become a necessary means for various logistics companies to enhance their market competitiveness. In many logistics warehouses, in order to save space, the height of storage racks is usually increased, and Design corresponding storage and retrieval equipment, and for larger or heavier items, high-position forklifts have become flexible, efficient and fast storage and retrieval tools in logistics warehouses. Moreover, usually after the high-position forklift has taken the items, the storage container (such as a pallet) containing the items needs to be returned to the corresponding storage contai...
