Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to the field of mechanical component technology, specifically referring to a lifting and palletizing workstation. Background Technology

[0002] Stacking refers to the act or process of neatly stacking items, and is widely used in logistics, warehousing and other fields.

[0003] Palletizing refers to the act of neatly stacking items (such as bags of rice, boxed goods, etc.) manually or mechanically. Manual palletizing is common in traditional warehousing scenarios. Mechanical assistance includes forklift palletizing (different methods such as crimping and overlapping) or automated palletizing machines (which achieve standardized stacking through identification, grasping, and handling).

[0004] With the advancement of technology, robotic arms are frequently used for palletizing. However, due to the limitation of palletizing height, some robotic arms can only palletize to a certain height. In order to use palletizing at higher heights, there is an urgent need for a workstation that can drive the robotic arm to lift and lower. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a lifting palletizing workstation that drives a robotic arm to move along the height direction, thereby enabling palletizing at different heights.

[0006] This utility model is achieved through the following technical solution: a lifting and palletizing workstation includes a base, a lifting platform located on the base, and a robotic arm detachably connected to the top surface of the lifting platform. The base is also provided with a housing that surrounds the lifting platform circumferentially. The housing is provided with a slide rail extending in the height direction. The lifting platform is provided with a slide seat that slides on the slide rail. The base is also provided with a first driving device that drives the lifting platform to lift.

[0007] In use, the first driving device drives the lifting platform to move, thereby enabling the base to move along the height direction. At the same time, the slide rail and slide block serve as guides and fixation.

[0008] Preferably, the first driving device includes a motor, a worm gear reducer connected to the output shaft of the motor, and a first lead screw connected to the output shaft of the worm gear reducer and extending in the height direction, wherein the first lead screw is threadedly connected to the lifting platform.

[0009] This preferred solution achieves the lifting function by using a worm gear reducer in conjunction with a motor, and also incorporates a lead screw drive to ensure its stability and accuracy.

[0010] Preferably, the front end of the base is fixedly connected to a fixing plate with a longitudinal length greater than that of the base, the robotic arm extends forward, and the fixing plate is bolted to the ground.

[0011] In this preferred embodiment, because the robotic arm performs palletizing in front, the center of gravity of the entire workstation will shift forward. To ensure the stability of the workstation, a fixing plate is added.

[0012] Preferably, a second lead screw located on the side of the first lead screw is axially connected to the housing. The second lead screw is threadedly connected to the lifting platform. A first sprocket is fixedly connected to the first lead screw, and a second sprocket is fixedly connected to the second lead screw. The first sprocket and the second sprocket are connected by a chain.

[0013] In use, this preferred solution uses a second lead screw to work in conjunction with the first lead screw to lift the platform, which also facilitates the stable lifting of the platform.

[0014] Preferably, the base is provided with a first cylinder located in front of the lifting platform, the seat of the first cylinder is hinged to the base, and the extended end of the first cylinder is hinged to the lifting platform.

[0015] In this preferred design, the extension and retraction of the first cylinder supports the lifting platform, preventing the robotic arm from tipping forward during stacking.

[0016] Preferably, the side of the lifting platform is also provided with a limiting plate that moves toward the lifting platform. The limiting plate is provided with a plurality of limiting blocks arranged along the height direction. The limiting blocks are inserted into a positioning plate arranged in a U-shape. The two side walls of the positioning plate pass through the housing and are connected to the slide. The housing is provided with an elongated hole for the two side walls of the positioning plate to slide. The positioning plate is provided with a through groove for the limiting blocks to be inserted.

[0017] In this preferred embodiment, after the lifting platform is raised or lowered, the slide also rises or lowers accordingly. At this time, the positioning plate rises or lowers along with the slide. When it rises or lowers to a certain position, the limiting plate moves toward the housing and the limiting block is inserted into the positioning plate, thereby fixing the positioning plate, that is, fixing the position of the slide. This allows the slide to provide a certain support for the lifting platform, thereby further improving the stability of the lifting platform.

[0018] Preferably, the limiting block is provided with a bidirectional electric push rod extending along the arrangement direction of the two side walls of the positioning plate. A fixing block inserted into the side wall of the positioning plate is fixedly connected to the extended end of the bidirectional electric push rod. The limiting block is provided with a sliding groove for the fixing block to slide.

[0019] In use, when the limiting block is inserted into the positioning plate, the bidirectional electric push rod is driven to extend, so that the fixing block is inserted into the positioning plate, thereby further improving the connection strength between the limiting block and the positioning plate.

[0020] The beneficial effects of this utility model are as follows: the first driving device drives the lifting platform to move, thereby realizing the movement of the base along the height direction, while the slide rail and slide block serve as guides and fixation; the lifting function is achieved by using a worm gear reducer with a motor, and the screw drive ensures its stability and accuracy; since the robotic arm stacks in front during use, the center of gravity of the entire workstation will shift forward, so a fixing plate is added to ensure the stability of the workstation; after the lifting platform is raised and lowered, the slide block also rises and falls, and the positioning plate rises and falls with the slide block. When it rises and falls to a certain position, the limiting plate moves towards the housing and the limiting block is inserted into the positioning plate, thereby fixing the positioning plate, that is, fixing the position of the slide block, so that the slide block provides a certain support for the lifting platform, thereby further improving the stability of the lifting platform.
