[0025] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.
[0026] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.
[0027] like Figures 1 to 4 As shown, this utility model provides a workpiece centering adjustment device, comprising:
[0028] The suspension frame 1 is provided with a gripping mechanism 2 for gripping or releasing the workpiece 6 located below the suspension frame 1;
[0029] The lifting mechanism 4 is used to connect with the suspension frame 1 to realize the vertical lifting of the suspension frame 1;
[0030] A floating centering module 3 is disposed at the bottom of the suspension frame 1. The floating centering module 3 has a locked state and an unlocked state and can switch between the locked state and the unlocked state. When the floating centering module 3 is in the unlocked state, the suspension frame 1 is allowed to translate in the horizontal plane or rotate 360 degrees in the horizontal plane. When the floating centering module 3 is in the locked state, the suspension frame 1 is restricted from translating in the horizontal plane or rotating 360 degrees in the horizontal plane.
[0031] In this embodiment, the lifting mechanism 4 drives the suspension frame 1 to move downward toward the workpiece 6. When the gripping mechanism 2 moves to the surface of the workpiece 6, the gripping mechanism 2 grips the workpiece 6. Then, the lifting mechanism 4 drives the suspension frame 1 to rise, so that the workpiece 6 rises to a certain height. Afterward, the floating centering module 3 drives the suspension frame 1 to translate in the horizontal plane or rotate 360 degrees in the horizontal plane. This allows the workpiece 6 on the gripping mechanism 2 to be positioned at the target position, so that the workpiece 6 can be accurately positioned at the target position. For example, when the floating centering module 3 is in the unlocked state, the suspension frame 1 can translate in the horizontal plane or rotate 360 degrees in the horizontal plane. After the suspension frame 1 translates or rotates to the target position, the floating centering module 3 is switched to the locked state so that the position of the suspension frame 1 in the horizontal plane is fixed during the lifting process, which facilitates the subsequent lowering of the workpiece 6. Since the floating centering module 3 has a locked state and an unlocked state and can switch between the locked state and the unlocked state, the translation or rotation angle of the suspension frame 1 in the horizontal plane can be flexibly adjusted, thereby increasing the adjustment range of the suspension frame 1 in the horizontal position and the fine adjustment accuracy is high, which effectively improves the positioning accuracy of the workpiece 6.
[0032] It should be noted that the floating centering module 3 of this utility model is the product with model number MACM4-20SP-X131.
[0033] It can be understood that the ability of the suspension frame 1 to translate in the horizontal plane means that the suspension frame 1 can move forward, backward, left, and right in the horizontal plane.
[0034] The workpiece centering adjustment device of this utility model realizes the lifting and lowering movement of the suspension frame 1 through the lifting mechanism 4, and realizes the automatic grasping and release of the workpiece 6 through the gripping mechanism 2. With the help of the floating centering module 3, the suspension frame 1 can translate in the horizontal plane or rotate 360 degrees in the horizontal plane, so that the suspension frame 1 is positioned at the target position, thereby accurately positioning the workpiece 6 on the gripping mechanism 2 at the target position. It has the advantages of high position compensation accuracy, fast adjustment speed, and high versatility. The workpiece centering adjustment device of this utility model, through the coordinated cooperation of the suspension frame 1, the suction mechanism, the lifting mechanism 4 and the floating centering module 3, effectively solves the defects of existing workpiece centering adjustment devices, such as complex structure, troublesome disassembly and assembly, slow adjustment speed, low accuracy, poor versatility and low degree of automation.
[0035] As a preferred embodiment, a pneumatic actuator is also included, which is configured to drive the floating centering module 3 to switch between a locked state and an unlocked state by air pressure.
[0036] In this embodiment, the floating centering module 3 has an unlocking vent and a locking vent. The pneumatic actuator includes an air passage one connected to the unlocking vent and an air passage two connected to the locking vent. When air is supplied to air passage one, the floating centering module 3 is unlocked; when air is supplied to air passage two, the floating centering module 3 is locked. The pneumatic actuator enables the floating centering module 3 to switch between the locked and unlocked states, offering advantages such as high automation and convenient operation and control.

[0038] In this embodiment, by setting the floating centering module 3 between the base plate 11 and the floating frame 12, the floating frame 12 is driven by the floating centering module 3 to translate relative to the base plate 11 in the horizontal plane or rotate 360 degrees in the horizontal plane. The gripping mechanism 2 is installed on the floating frame 12. The structure is simple and compact, and the design is ingenious, ensuring the stability of the gripping mechanism 2 in lifting the workpiece 6 and the convenience of installation.
[0039] In a preferred embodiment, a plurality of floating alignment modules 3 are provided between the floating frame 12 and the base plate 11. This enables the floating frame 12 to undergo stable translation or rotation in the horizontal plane.
[0040] In a preferred embodiment, multiple floating alignment modules 3 are arranged in an array between the floating frame 12 and the base plate 11. The array arrangement of multiple floating alignment modules 3 helps to evenly distribute forces and achieve stability of the floating frame 12.
[0041] In a preferred embodiment, a plurality of gripping mechanisms 2 are installed on the outer periphery of the floating frame 12. This facilitates the gripping mechanisms 2 in gripping or releasing the workpiece 6.
[0042] In a preferred embodiment, the gripping mechanism 2 includes a mounting component 21 detachably connected to the floating frame 12 and a suction cup 22 connected to the mounting component 21. The suction cup 22 is provided with a pneumatic connector for connecting to negative pressure.
[0043] In this embodiment, the mounting components 21 are vertically installed at the four corners of the floating frame 12. The mounting components 21 and the floating frame 12 can be connected by threads. The workpiece 6 is adsorbed by suction cups 22, which features fast gripping and releasing speed and stable lifting. Of course, in other embodiments, the gripping mechanism 2 can also be a magnetic suction mechanism.
[0044] In a preferred embodiment, a fixed plate 5 is also included, one end of the lifting mechanism 4 is connected to the fixed plate 5, and the other end of the lifting mechanism 4 is connected to the base plate 11.
[0045] In this embodiment, the position of the fixed plate 5 is fixed. The lifting mechanism 4 can be one of a telescopic cylinder, an electric push rod, a hydraulic push rod, or any combination thereof. There can be one or more sets, all of which are arranged vertically. The lifting mechanism 4 drives the base plate 11 to move up and down relative to the fixed plate 5 in the vertical direction, thereby realizing the lifting of the suspension frame 1.
[0046] In a preferred embodiment, the base plate 11 is provided with a plurality of vertically arranged guide posts 13, the fixing plate 5 is provided with a plurality of sleeves 51 that cooperate with the guide posts 13, and the middle part of the floating frame 12 is provided with a clearance through hole for avoiding the guide posts 13 and the lifting mechanism 4.
[0047] In this embodiment, the design of the guide post 13 and the sleeve 51 ensures that the base plate 11 moves accurately along the direction specified by the guide post 13, avoiding deviation, so that the entire suspension frame 1 can be raised and lowered stably and accurately. The design of avoiding the through hole ensures that the structure is compact and does not affect the operation of the lifting mechanism 4.

[0049] In this embodiment, the lifting mechanism 4, the gripping mechanism 2, and the pneumatic actuator are each connected to the controller via electrical connections such as wires. This allows the controller to send control signals to these mechanisms to control their start-up, stop, speed, and direction of movement. It can also receive status information from these mechanisms, thus achieving automated control of the entire system. For example, the controller can send control signals to these three mechanisms according to a preset program or received instructions, causing them to perform corresponding actions as required. This includes controlling the lifting mechanism 4 to rise or fall, controlling the gripping mechanism 2 to grip or release items, and controlling the pneumatic actuator to control the floating centering module 3.
