Description

Technical Field

[0001] The utility model relates to the field of mechanical devices, in particular to a mechanical cup grabbing mechanism. Background Art

[0002] The cup gripping mechanism is a part of mechanical equipment, which is mainly used to grab, carry, flip or release cups and other containers in the automated production line. It can improve production efficiency, reduce manual operations, reduce labor intensity, and ensure product production quality and consistency.

[0003] The existing cup grabbing mechanisms on the market are mainly composed of two types: a clamping cylinder and a suction cup structure. The suction cup structure is easily affected by external environmental factors during the grabbing process, which greatly reduces its grabbing stability; and the clamping cylinder can only achieve one cylinder corresponding to one grabbing station, which leads to high production and manufacturing costs of this grabbing structure. Based on the above problems, the present invention was born. Utility Model Content

Under the action of the grabbing linkage component, the grabbing unit drives each claw block to expand and contract around the central position around which it is arranged to achieve the grabbing function. This setting structure is not affected by external environmental factors and only requires one driving source as power, so as to achieve the advantages of stable grabbing, long service life and low production cost.

[0007] It is further configured as follows: the claw seat is movably arranged on the mounting plate and the claw seat drives each claw block to move through a grabbing linkage component.

[0010] By adopting the above technical solution, the claw seat rotates through the grabbing linkage structure and the grabbing linkage arm to drive the claw block to rotate eccentrically, so as to realize the contraction and expansion function of the claw block to achieve the purpose of grabbing.

[0011] It is further configured as follows: the grabbing linkage structure includes a grabbing linkage groove and a grabbing linkage rod extending into the grabbing linkage groove.

[0012] By adopting the above technical solution, the grabbing linkage groove cooperates with the grabbing linkage rod to realize the linkage between the grabbing linkage arm and the claw seat, and the structure can well compensate for the travel tolerance generated by the linkage between the two to achieve the purpose of stable linkage.

[0013] It is further configured as follows: the linkage member includes a primary linkage component constituting the linkage of each grabbing unit and a secondary linkage component constituting the linkage between the primary linkage component and the driving source.

[0014] By adopting the above technical solution, the cooperation between the primary linkage component and the secondary linkage component can realize the linkage between the driving source and multiple grasping units, which can achieve more stable majority control purposes.

[0015] It is further configured as follows: the primary linkage component includes a primary linkage arm slidably arranged on the mounting plate and a primary linkage structure formed between each claw seat and the primary linkage arm.

[0016] By adopting the above technical solution, the cooperation between the primary linkage arm and the primary linkage structure is used to realize the primary linkage arm driving the movement of multiple grabbing units, which has a simple structure and low processing cost.

[0017] It is further configured as follows: the primary linkage structure includes a primary linkage rod moving with the claw seat, a primary linkage slot arranged on the primary linkage arm, and a primary linkage column connected to the primary linkage rod and extending into the primary linkage slot.

[0018] By adopting the above technical solution, the first-level linkage arm, the first-level linkage groove and the first-level linkage column cooperate to realize the linkage between the first-level linkage arm and the claw seat, and the structure can well compensate for the stroke tolerance generated by the linkage between the two to achieve the purpose of stable linkage.

[0020] By adopting the above technical solution, the setting of the limiting wheel can ensure the stable sliding of the primary linkage rod on the mounting plate, so as to ensure the stability and feasibility of the structure.

[0021] It is further configured as follows: the secondary linkage component includes a secondary linkage arm hinged to the mounting plate, a secondary linkage rod driven by a driving source, a secondary linkage slot arranged on the secondary linkage arm and for the secondary linkage rod to be inserted into, and a secondary linkage column connecting the primary linkage component and the secondary linkage arm.

[0022] By adopting the above technical solution and the above structure, the linkage between the driving source and the primary linkage component is achieved.

[0023] It is further configured as follows: the grabbing linkage rod is provided with a roller which rolls with the grabbing linkage groove.

[0024] By adopting the above technical solution, the roller is set to reduce the wear on the linkage structure, thereby extending the service life of the structure and improving the grasping accuracy of the structure.

[0025] In summary, the utility model has the following beneficial effects: the utility model has stable grasping, long service life and low production cost. BRIEF DESCRIPTION OF THE DRAWINGS
