Description

Technical Field

[0001] The utility model relates to the technical field of automated production, in particular to a rotary gripper mechanism. Background Art

[0002] Gripper applications are widespread in automated production lines, primarily in material handling, assembly, and sorting. Grippers can be used to pick up and move parts, improving production efficiency. Grippers are particularly useful for the suction and displacement of flat materials during production and processing.

[0003] With the emergence of more diverse shapes and sizes of flat materials, the requirements for grippers are becoming increasingly higher. For example, when adsorbing some flat perforated materials, the suction cups on traditional grippers can easily get stuck on the perforated areas, making it difficult to absorb the materials or causing them to fall due to insufficient adsorption force. On the other hand, when adsorbing and shifting flat materials of different shapes and sizes, the matching grippers need to be replaced for adsorption, resulting in lower applicability.

[0004] Therefore, there is an urgent need for a rotary gripper mechanism to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of the present invention is to provide a rotary suction device mechanism to solve the problems of low applicability of traditional suction devices and poor adsorption when adsorbing flat punched materials.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] As an optional technical solution for a rotary gripper mechanism, the vacuum module includes a top plate, a vacuum generator and a plurality of logic valves mounted on the top plate, and the plurality of logic valves are connected to the plurality of vacuum nozzle pipes.

[0010] As an optional technical solution for a rotary clamp mechanism, the driving assembly includes a motor, a reducer and a transmission shaft connected in sequence, and the "cross"-shaped mounting bracket is fixed to the end of the transmission shaft away from the reducer.

[0012] As an optional technical solution of the rotary clamp mechanism, two limit sensors are provided, and the reset sensor is installed between the two limit sensors.

[0013] As an optional technical solution for a rotating suction device mechanism, two vacuum suction nozzles are respectively arranged on the left and right sides of the "cross" mounting frame in the X-axis direction, and a vacuum suction nozzle is respectively arranged on the upper and lower sides of the "cross" mounting frame in the Y-axis direction, and the lower end of the vacuum suction nozzle is connected to a vacuum suction cup.

[0014] As an optional technical solution for the rotary gripper mechanism, the fixing frame is in an "L"-shaped structure, and a reinforcement piece is installed at each inner corner of the two sides of the fixing frame.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0029] In the description of this embodiment, the terms "up", "down", "left", "right" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0030] In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] like Figure 1 As shown, the utility model provides a rotary suction cup mechanism, which includes a fixed frame 1, a vacuum module 2 is fixedly provided on the top of the fixed frame 1, and the vacuum module 2 is used to generate negative pressure; a driving component 3 is installed on the fixed frame 1 and is located below the vacuum module 2; a suction cup assembly 4 includes a "cross"-shaped mounting frame 40 connected to the output end of the driving component 3, and a plurality of vacuum suction nozzles 41 are symmetrically provided in the X-axis and Y-axis directions of the "cross"-shaped mounting frame 40.

[0032] The utility model provides a rotary suction device mechanism, which is capable of simultaneously performing multi-point suction on planar materials in the X-axis and Y-axis directions by symmetrically arranging a plurality of vacuum suction nozzles 41 in the X-axis and Y-axis directions of a "cross"-shaped mounting frame 40. When suctioning planar punched materials, when some suction nozzles are sucked at the punching positions, the materials can also be firmly sucked in by other suction nozzles on the X-axis and Y-axis. More importantly, the plurality of vacuum suction nozzles 41 on the "cross"-shaped mounting frame 40 can cooperate at different coordinates to suck planar materials of different shapes and sizes, making the rotary suction device mechanism more widely applicable.

[0033] Specifically, such as Figures 1 to 3 As shown, the "cross"-shaped mounting frame 40 is provided with two vacuum suction nozzles 41 on the longer left and right sides in the X-axis direction, and a vacuum suction nozzle 41 is provided on the shorter upper and lower sides in the Y-axis direction. Thus, the six vacuum suction nozzles 41 are arranged in a "cross" shape with one long and one short spaced apart. When sucking some rectangular planar materials, the vacuum suction nozzles 41 on the shorter upper and lower sides in the Y-axis direction suck on the width surface of the planar material, and the vacuum suction nozzles 41 on the longer left and right sides in the X-axis direction suck on the length surface of the planar material. When sucking some square or round planar materials, the vacuum suction nozzles 41 on the shorter upper and lower sides in the Y-axis direction suck and suck the square or round planar materials together with the two vacuum suction nozzles 41 near the center of the "cross"-shaped mounting frame 40. When it is necessary to suck some planar materials of different shapes or sizes, the multiple vacuum suction nozzles 41 on the "cross"-shaped mounting frame 40 can be used to suck at different coordinates. There is no need to replace the suction fixture for different planar materials, making the applicability of the rotary suction fixture more extensive. Of course, the number of vacuum suction nozzles 41 on the "cross"-shaped mounting frame 40 can also be adjusted according to the requirements of the adsorption operation, and a vacuum suction cup 410 is connected to the lower end of each vacuum suction nozzle 41. The vacuum suction cup 410 is used to increase the adsorption of flat materials, making the adsorption and displacement operation of flat materials more firm and stable.

[0034] In this embodiment, if Figure 1 As described, the vacuum module 2 includes a top plate 20 and a vacuum generator 21 and a plurality of logic valves 22 installed on the top plate 20. The number of logic valves 22 is preferably six, but not limited to six, and can be adjusted according to the number of vacuum suction nozzles 41. Each vacuum suction nozzle 41 is connected to the corresponding logic valve 22 by a pipeline; the main valve port of the six logic valves 22 is connected to the vacuum generator 21 by a pipeline; the negative pressure airflow generated by the vacuum generator 21 is used to realize the adsorption force of the vacuum suction nozzle 41 on the material, and the setting of the logic valve 22 makes it possible to adsorb some flat punching materials. When a vacuum suction nozzle 41 on the "cross"-shaped mounting bracket 40 is adsorbed at the punching place, the corresponding logic valve 22 is closed at this time, so that the suction force of other vacuum suction nozzles 41 is stronger, avoiding the influence of insufficient negative pressure on the adsorption of materials; therefore, when some suction nozzles are adsorbed at the punching place, the materials can also be firmly sucked in by other suction nozzles on the X-axis and Y-axis. This structure improves the adsorption stability of flat punching materials.

[0035] Furthermore, the driving assembly 3 includes a motor 30, a reducer 31 and a transmission shaft 32 connected in sequence. The "cross"-shaped mounting bracket 40 is fixed to the end of the transmission shaft 32 away from the reducer 31. An arc-shaped mounting plate 5 is provided on the surface of the fixing bracket 1 close to the transmission shaft 32. A reset sensor 6 and two limit sensors 7 are installed on the arc-shaped mounting plate 5. The reset sensor 6 is installed between the two limit sensors 7. This structure makes the reset sensor 6 and the two limit sensors 7 on the same circumference. An induction plate 8 matching the reset sensor 6 and the limit sensors 7 is installed on the transmission shaft 32. Through the setting of the reset sensor 6 and the limit sensor 7, the suction assembly 4 can reciprocately adsorb and shift the material within a limited angle range; the rotation angle of the suction assembly 4 can also be changed by adjusting the position of the two limit sensors 7 on the arc-shaped mounting plate 5 to achieve adsorption and shifting of materials at different angles; in this embodiment, the motor 30 is preferably a servo motor 30, but is not limited to a servo motor 30.

[0036] Specifically, the fixing frame 1 has an "L"-shaped structure, and a reinforcement member 10 is installed at the inner corners on both sides of the fixing frame 1. The reinforcement member 10 is arranged in an "L" shape. Through the arrangement of the reinforcement member 10, the stability and rigidity of the entire rotary clamp mechanism are higher, thereby improving the service life of the mechanism.

[0037] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technology of the present invention, which do not depart from the content of the technical solution of the present invention, are within the scope of the technical solution of the present invention.
