Description

Technical Field

[0001] This application relates to the field of automated stamping workshops, and specifically to a suction cup mounting mechanism and a material transfer device. Background Technology

[0002] In automated stamping workshops, end effectors are key devices for gripping sheet metal, and the ease of replacement of their suction cups and their operational stability directly affect production efficiency.

[0003] Currently, the traditional suction cup fixing structure used in end effectors is mostly fixed by threads. Each time the suction cup is replaced, the threads must be manually tightened, which not only consumes a lot of manpower and time, but also leads to extended production line downtime and significantly reduces production efficiency. At the same time, traditional structures are prone to poor stability and insufficient positioning accuracy after the suction cup is installed, making it difficult to meet the positioning accuracy requirements of automated production.

[0004] Furthermore, when adapting universal end effectors to different parts, some suction cups may be in continuous contact with the material due to their position at the edge of the material, which aggravates suction cup wear and shortens its service life. In addition, in traditional structures, if air circuit control is required to achieve the non-working state of the suction cup, an additional solenoid valve is usually required, which increases equipment costs, structural complexity, and maintenance difficulty, making it impossible to balance economy and practicality. Therefore, existing suction cup installation and retraction technologies are no longer able to meet the production needs of automated stamping workshops for high efficiency, stability, and low cost. Utility Model Content

[0005] To solve or at least partially solve the above-mentioned technical problems, this application provides a suction cup mounting mechanism, including: a rotating disk and a fixed base, wherein one end of the rotating disk is detachably connected to the target suction cup through a threaded connector, and the other end is rotatably engaged with the fixed base through a connector;

[0006] The rotating disk has a mounting hole, and a knob plunger is provided in the mounting hole. The fixed base has at least one mating hole.

[0007] The fixed base is also provided with a first air connector, and the rotating disk is also provided with a connecting channel, which is connected to the suction cup air connector through a second air connector provided on the rotating disk; wherein...

[0008] The rotating disk has a first position and a second position. When the rotating disk is in the first position, the first air connector is connected to the connecting channel, and the target suction cup grabs the target material. When the rotating disk rotates to the second position relative to the fixed seat, the first air connector is disconnected from the connecting channel, the knob plunger is at least partially inserted into the mating hole, and the suction cup is retracted to a direction away from the target material.

[0009] Optionally, the rotating disk includes a first plate and a second plate arranged at an angle, the first plate having a connecting hole, and the first plate engaging with the connecting hole via a threaded connector to be detachably connected to the target suction cup.

[0010] Both the knob plunger and the connector are located on the second plate.

[0011] Optionally, the first plate and the second plate are arranged perpendicularly.

[0012] Optionally, the first plate and the second plate are integrally formed.

[0013] Optionally, the connector is a connecting screw, which is located in the middle of the second plate.

[0014] The second plate is connected to the fixing seat by the connecting screw.

[0015] Optionally, the number of mating holes is two, and the two mating holes are respectively located on opposite sides of the vertical direction of the fixing seat;

[0016] When the rotating disk is in the first position, the angle between the line connecting the mounting hole and the connector and the line connecting any of the mating holes and the connector is 90 degrees.

[0017] Optionally, the rotating disk has a bushing at one end near the fixed base, and the connecting member passes through the bushing and is connected to the fixed base.

[0018] Optionally, the end of the first air connector is provided with a sealing gasket, one end of which abuts against the end face of the rotating disk facing the fixed seat.

[0019] This application also proposes a material transfer device, including a suction cup and a suction cup mounting mechanism as described above, wherein the suction cup is detachably connected to the suction cup mounting mechanism via a threaded connector.

[0020] Optionally, one end of the suction cup is provided with a stud, and one end of the stud passes through the connecting hole and is connected to the rotating disk through a locking nut.

[0021] The suction cup mounting mechanism provided in this application, through the rotational cooperation between the rotating disk and the fixed base, combined with the on / off design of the first air connector and the connecting channel inside the rotating disk, enables the rotating disk to stably achieve the suction cup gripping operation of the material sheet when in the first position, and allows the suction cup to be retracted away from the material sheet when rotated to the second position. This avoids wear caused by the suction cup contacting the material sheet when not in operation, extends the service life of the suction cup, and automatically realizes the air circuit on / off without the need for an additional solenoid valve, reducing equipment cost and structural complexity.

[0022] Moreover, the detachable connection design between the rotary disk and the target suction cup eliminates the cumbersome operation of manually tightening the traditional threaded fixing, greatly shortens the suction cup replacement time, reduces manpower consumption, reduces production line downtime, and improves production efficiency.

[0023] The locking structure of the knob plunger and the fixed seat hole ensures that the rotating disk remains stable in both the first and second positions, effectively solving the problems of poor stability and insufficient positioning accuracy of traditional suction cups after installation. This ensures the reliability of suction cup positioning during operation and further adapts to the efficient and stable production needs of automated stamping workshops. Attached Figure Description

These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0035] The following flowchart illustrates the operations performed to improve the safety performance of a vehicle. It should be understood that, depending on the actual situation, the preceding or following operations may not be performed precisely in sequence. Other operations may be added to these processes, or one or more operations may be removed from them.

[0036] The technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0037] like Figures 1 to 4 As shown, this utility model provides a suction cup mounting mechanism, including a rotating disk 1 and a fixed base 2. One end of the rotating disk 1 is detachably connected to the target suction cup 3 via a threaded connector, and the other end is rotatably engaged with the fixed base 2 via a connector 4. The rotating disk 1 has a mounting hole 11, and a knob plunger 12 is provided in the mounting hole 11. The fixed base 2 has at least one mating hole 21. The fixed base 2 also has a first air connector 22, and the rotating disk 1 also has a connecting channel 13. The connecting channel 13 is connected to the suction cup air connector 33 via a second air connector 17 provided on the rotating disk 1. The rotating disk 1 has a first position and a second position. When the rotating disk 1 is in the first position, the first air connector 22 is connected to the connecting channel 13, and the target suction cup 3 grasps the target material. When the rotating disk 1 rotates relative to the fixed base 2 to the second position, the first air connector 22 is disconnected from the connecting channel 13, the knob plunger 12 is at least partially inserted into the mating hole 21, and the suction cup is retracted to a direction away from the target material.

[0038] This application utilizes the rotational cooperation between the rotating disk 1 and the fixed base 2, combined with the on / off design of the first air connector 22 and the internal connecting channel 13 of the rotating disk 1, to enable the rotating disk 1 to stably perform the gripping operation of the suction cup on the material sheet when in the first position, and to allow the suction cup to retract away from the material sheet when rotating to the second position. This avoids wear caused by the suction cup contacting the material sheet when not in operation, extends the service life of the suction cup, and automatically realizes the on / off of the air path without the need for an additional solenoid valve, reducing equipment cost and structural complexity.

[0039] Please refer to Figure 1 and Figure 2The first air connector 22 is connected to the connecting channel 13. The external drive unit can be connected to the suction cup air connector 33 through the first air connector 22, the connecting channel 13, and the second air connector 17, thereby drawing gas from the target suction cup 3 so that the target suction cup 3 can grasp the material.

[0040] Specifically, the suction cup air connector 33 can be located at the top of the threaded connector, that is, the threaded connector has a cavity in the middle, one end of the cavity extends to the suction cup gripping end, and the other end is connected to the suction cup air connector 33.

[0041] Alternatively, the suction cup air connector 33 can be located on the side of the suction cup. Different settings can be adjusted according to requirements, and no limitation is made here.

[0042] When the rotating disk 1 rotates to a certain angle, the first air connector 22 is disconnected from the connecting channel 13. That is, the connecting channel 13 has only one opening on the side facing the fixed base 2, and the first air connector 22 is connected to the connecting channel 13 only when the target suction cup 3 is in working condition.

[0043] Moreover, the detachable connection design between the rotating disk 1 and the target suction cup 3 eliminates the cumbersome operation of manually tightening the traditional threaded fixing, greatly shortens the suction cup replacement time, reduces manpower consumption, reduces production line downtime, and improves production efficiency.

[0044] By setting the knob plunger 12 and the locking structure of the knob plunger 12 and the fixing seat 2 mating hole 21, it can be ensured that the rotating disk 1 remains stable in both the first and second positions. This effectively solves the problems of poor stability and insufficient positioning accuracy after the traditional suction cup is installed, ensuring the reliability of the suction cup positioning during operation and further adapting to the efficient and stable production needs of automated stamping workshops.

[0045] In other words, this application enables flexible switching between working and non-working states for the suction cup. During operation, the air path remains stable to ensure reliable gripping, while during non-working, the air supply is automatically shut off to reduce air consumption and eliminate the need for an additional solenoid valve. Simultaneously, the suction cup is retracted away from the material to prevent wear. The threaded connector allows for quick assembly and disassembly of the suction cup, solving the time-consuming problem of traditional threaded fasteners. The knob plunger 12 and the mating hole 21 ensure stability of the mechanism in both positions, improving positioning accuracy, reducing labor and time costs, and increasing production efficiency.

[0046] Please refer to Figure 2 and Figure 3 The rotating disk 1 includes a first plate 14 and a second plate 15 set at an angle. The first plate 14 has a connecting hole 141. The first plate 14 is connected to the connecting hole 141 by a threaded connector to be detachably connected to the target suction cup 3. The knob plunger 12 and the connector 4 are both set on the second plate 15.

[0047] By dividing the functions of the rotating disk 1 into zones, the suction cup connection, mechanism rotation, and locking components can be set on different plates, making the layout of each component clearer and more reasonable, thereby avoiding mutual interference.

[0048] Meanwhile, the angled structure can optimize the installation angle and position of the suction cup, making it easier to adapt to different material gripping needs, improving the adaptability of the mechanism to the working scenario, and simplifying assembly and maintenance operations, reducing the difficulty of component repair.

[0049] Optionally, the first plate 14 and the second plate 15 are arranged vertically.

[0050] The first plate 14 and the second plate 15 are arranged vertically, which allows for precise control of the suction cup's gripping and retraction directions. This ensures that the suction cup can move vertically away from the material when not in operation, minimizing the risk of contact with the material. Simultaneously, the vertical structure facilitates manufacturing, reduces production difficulty, and enhances the overall structural strength of the rotating disk 1, reducing deformation during use and extending the service life of the suction cup mounting mechanism.

[0051] Optionally, the first plate 14 and the second plate 15 are integrally formed.

[0052] The one-piece molding structure eliminates the connection gaps between adjacent plates, improving the overall rigidity and structural stability of the rotating disk 1. It avoids problems such as loosening and displacement caused by long-term use of separate connections, ensuring the positioning accuracy of the suction cup. Moreover, one-piece molding reduces assembly processes and connecting parts, lowers production and assembly costs, shortens the production cycle, and the absence of connection gaps reduces dust and impurity accumulation, lowers maintenance frequency, and improves the reliability of the mechanism.

[0053] In one embodiment, the connector 4 is a connecting screw, which is located in the middle of the second plate 15; the second plate 15 is connected to the fixing seat 2 by the connecting screw.

[0054] Because connecting screws are readily available, inexpensive, and easy to disassemble and maintain, connecting screws are used to connect the second plate 15 and the fixing seat 2.

[0055] By placing the connecting screws in the middle of the second plate 15, the rotating disk 1 can be subjected to uniform force, avoiding jamming and uneven wear caused by force imbalance during rotation, and ensuring smooth rotation.

[0056] Meanwhile, the central connection can improve the coaxiality of the connection between the rotating disk 1 and the fixed seat 2, further improve the positioning accuracy of the mechanism, ensure accurate connection when the gas circuit is open or closed, and reduce the risk of gas circuit leakage.

[0057] Optionally, there are two mating holes 21, and the two mating holes 21 are respectively located on opposite sides of the vertical direction of the fixed base 2; when the rotating disk 1 is in the first position, the angle between the line connecting the mounting hole 11 and the connector 4 and the line connecting any mating hole 21 and the connector 4 is 90 degrees.

[0058] The two mating holes 21 correspond to the first and second positions of the rotating disk 1, respectively, which can achieve precise locking in the two states and avoid positioning deviations that may occur with a single mating hole 21.

[0059] The 90-degree angle design clearly defines the rotation stroke of the rotating disk 1, ensuring that the suction cup can be accurately retracted to an angle away from the material when not in operation. At the same time, it simplifies operation, and the staff can quickly switch states by judging the angle, thus improving work efficiency.

[0060] In one embodiment, a bushing 16 is provided at one end of the rotating disk 1 near the fixed base 2, and the connecting member 4 passes through the bushing 16 and is connected to the fixed base 2.

[0061] In other words, bushing 16 can reduce the direct friction between rotating disk 1 and connecting part 4, reduce the wear rate of components, and extend the service life of connecting part 4 and rotating disk 1. At the same time, bushing 16 can improve the coaxiality and smoothness of rotating disk 1, avoid deviation and jamming during rotation, and ensure accurate connection when the air passage is opened or closed.

[0062] Moreover, the bushing 16 can act as a buffer, reducing the impact when the rotating disk 1 switches states, protecting the mechanical components, and improving operational stability.

[0063] Please refer to Figure 1 and Figure 4 The end of the first air connector 22 is provided with a sealing gasket 23, and one end of the sealing gasket 23 abuts against the end face of the rotating disk 1 facing the fixed seat 2.

[0064] By setting the sealing gasket 23, the sealing performance between the first air connector 22 and the end face of the rotating disk 1 can be enhanced, preventing air leakage during operation, ensuring stable vacuum or air pressure during suction cup gripping, and improving gripping reliability. In non-operating conditions, the sealing gasket 23 also reduces the entry of external dust and impurities into the air circuit interface, protecting air circuit components, reducing the risk of air circuit blockage and malfunction, and extending the service life of the first air connector 22, thus reducing maintenance costs.

[0065] This application also proposes a material transfer device, including a suction cup and the suction cup mounting mechanism as described above, wherein the suction cup is detachably connected to the suction cup mounting mechanism via a threaded connector.

[0066] Since the material transfer device includes the suction cup mounting mechanism described above, it has all the advantages of the suction cup mounting mechanism, which will not be elaborated here.

[0067] Furthermore, one end of the suction cup is provided with a stud 31, one end of which passes through the connecting hole 141 and is connected to the rotating disk 1 through the locking nut 32.

[0068] The stud 31 and locking nut 32 are securely connected, effectively preventing the suction cup from loosening or falling off due to vibration or stress during material transfer, thus ensuring operational safety. Furthermore, the assembly and disassembly are simple, allowing workers to quickly replace the suction cup without special tools, further reducing maintenance time and production line downtime.

[0069] Moreover, this connection method can be adapted to suction cups of different specifications. Simply replace the suction cup with the corresponding stud size 31 to improve the device's adaptability to different materials.

[0070] Please continue to refer to Figure 1 The stud 31 is hollow and passes through the connecting hole 141. One end of the stud 31 is connected to the suction cup, and the other end is engaged with the locking nut 32. The suction cup air connector 33 can be inserted into the internal cavity of the stud 31 and is threaded into the stud 31.

[0071] When the suction cup is in working condition, the first air connector 22 is connected to the second air connector 17 through the connecting channel 13, and the second air connector 17 is connected to the suction cup air connector 33 through a pipeline (not shown in the figure), thereby the suction cup gripping end can form a negative pressure and grip the material.

[0072] When the rotating disk 1 rotates at a certain angle relative to the fixed base 2, the first air connector 22 is disconnected from the connecting channel 13, and the suction cup automatically enters a non-working state.
