Description

Technical Field

[0001] This invention relates to the field of hose clamp processing technology, specifically to an eccentric wheel type feeding and welding device. Background Technology

[0002] Hose clamps are typically made from stainless steel strips, carbon steel strips, or aluminum strips. Based on the design requirements of the hose clamp, steel strips of the appropriate size and specifications are prepared. During the processing of the hose clamp steel strips, they need to be welded. In this process, the continuity and stability of the steel strip welding affect the welding efficiency.

[0003] The eccentric wheel feeding welding device was developed in response to this need. It innovatively integrates the principle of planetary gear trains with mechanical linkage control technology. Through its unique eccentric wheel structure and material rack design, it breaks through the limitations of traditional feeding methods. While solving the problem of maintaining the horizontal posture of materials, the device can realize continuous conveying of multiple workstations in a space-intensive manner, effectively eliminating intermittent stops during the conveying process. This technological innovation not only meets the needs of modern automated welding production lines for high-efficiency and high-precision material transmission, but also provides a brand-new solution for functional integration within a limited production space.

[0004] However, the traditional eccentric wheel feeding structure is not suitable for the production of hose clamp steel belts. Furthermore, due to the dense vibration of the eccentric disc and the low positioning accuracy, it is difficult to apply to the feeding and processing of hose clamp steel belts. In view of this situation, the present invention proposes a novel solution. Summary of the Invention

[0005] The purpose of this invention is to provide an eccentric wheel type feeding and welding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an eccentric wheel type feeding and welding device, comprising: The material handling device, two supports, two sets of eccentric wheel feeding and positioning components, and several material placement racks; The material racks are circumferentially and equidistantly installed between two sets of eccentric wheel feeding and positioning components. During the rotation of the eccentric wheel feeding and positioning components, the placement surface of each material rack is horizontal and facing upward. Both sets of eccentric wheel feeding and positioning components include a first eccentric wheel and a second eccentric wheel. The two ends of the feeding frame are connected to the second eccentric wheel through hinge blocks. The second eccentric wheel revolves around the axis of the first eccentric wheel and rotates on its own axis.

[0007] Further, an XY coordinate system is established with the center of arm wheel one. The centers of arm wheel one and arm wheel two are both located on the X-axis and are spaced cm-cm apart. Arm wheel one and arm wheel two are each equipped with six to twelve arms.

[0008] Further, each corresponding arm of the first arm and the second arm is connected by a hinge block. A wheel is fixed on the side of the first arm facing the second arm, and a notch is eccentrically opened on the wheel. A shaft is fixed on the side of the second arm facing the first arm, and the shaft is locked in the notch.

[0009] Further, the material rack includes two coaxial sleeves, both of which are connected to one end of the hinge block, and the coaxial sleeves pass through the second arm wheel and are fixed to one end of the hinge block.

[0010] Furthermore, each of the two coaxial sleeves has an insert block fixed at one end, and a shelf is inserted between the two insert blocks. Limiting components are fixed at both ends of the shelf.

[0011] Further, the limiting component includes a sliding sleeve, which is fixed to the surface of the shelf by bolts, and three limiting rods are fixed to the top surface of the sliding sleeve, with the axis of the three limiting rods forming an equilateral triangle.

[0012] Further, the material handling device includes a linear slide table that performs vertical stroke movement. A platform that moves linearly through the linear slide table is provided on one side of the linear slide table. At least two pneumatic telescopic tubes are installed on the platform. A top plate is fixed to the top of the pneumatic telescopic tubes, and a suction cup is fixed to the bottom of the top plate. The suction cup is directly opposite the top surface of one of the material racks.

[0013] Furthermore, in the initial state, the top surface of each shelf is horizontally upward and horizontal to one side of the hinge block.

[0014] Further, a drive source is installed on one side of one of the supports, and the output end of the drive source is coaxially fixed with the arm wheel of one of the eccentric wheel loading and positioning components.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The eccentric wheel feeding and welding device achieves material picking through the coordinated movement of two sets of eccentric wheel feeding and positioning components. Combined with the principle of planetary gear train, it ensures that the material is always in a horizontal state during the conveying process, effectively preventing tipping and slippage. Furthermore, the circumferentially spaced material racks, in conjunction with continuous rotational motion, achieve continuous and stable material conveying, improving production efficiency. It also has high space utilization and allows for multi-station operation.

[0016] Meanwhile, through the coordinated control of eccentricity and the number of support arms, high-density, zero-tilt, and customizable conveying can be achieved in a limited space. The application of structures such as articulated blocks and wheel discs reduces transmission backlash, ensures synchronized speed ratios, optimizes motion trajectory, reduces sudden acceleration changes, and improves material stability. The structural design of the material rack constrains the degree of freedom of swing, ensuring that the placement surface is horizontal.

[0017] Furthermore, the suction cup material handling device, combined with a linear slide and a pneumatic telescopic tube, achieves precise material suction and handling. Overall, this device boasts advantages such as high efficiency, stability, precision, space saving, and adaptability to multiple workstations, effectively improving production efficiency and quality. It is suitable for various industrial production scenarios, including material loading and welding. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1 As shown, the present invention provides a technical solution: an eccentric wheel type feeding and welding device, comprising: The material handling device, two supports 1, two sets of eccentric wheel feeding and positioning parts 2, and several material placement racks 3; The material rack 3 is installed in a circular shape at equal intervals between two sets of eccentric wheel feeding and positioning parts 2. During the rotation of the eccentric wheel feeding and positioning parts 2, the placement surface of each material rack 3 is horizontal and facing upward. Both sets of eccentric wheel loading and positioning components 2 include a first arm wheel 201 and a second arm wheel 202. The two ends of the material rack 3 are connected to the second arm wheel 202 through hinge blocks 203. The second arm wheel 202 revolves around the axis of the first arm wheel 201 and rotates on its own axis.

[0022] The device achieves material handling through the coordinated movement of two sets of eccentric wheel loading and positioning components 2: while the second arm wheel 202 revolves around the axis of the first arm wheel 201, it also rotates precisely on its own axis, and drives the material rack 3 to move through the hinge block 203. The core of this compound motion lies in its planetary gear system principle. The revolution of the material rack 3 is driven by the first arm wheel 201, while the rotation of the second arm wheel 202 is precisely controlled by mechanical linkage, ensuring that the placement surface of the material rack 3 can always maintain a horizontal posture at any angle of revolution. The material is always in a horizontal state during the continuous rotation and conveying of the material rack 3, which effectively prevents tipping and slippage. The circumferentially spaced material rack 3, combined with the continuous rotation of the eccentric wheels, realizes the continuous and stable conveying of materials, improves production efficiency, and the circumferential layout of the material rack 3 makes full use of space, allowing for multi-station operation.

[0023] To ensure the smooth implementation of this embodiment, it is necessary to understand that an XY axis coordinate system is established with the center of arm wheel 1 201. The centers of arm wheel 1 201 and arm wheel 2 202 are both located on the X-axis and the center interval is 10cm-30cm. Arm wheel 1 201 and arm wheel 2 202 are each equipped with six to twelve arms. The motion trajectory is precisely constrained by the eccentricity and the rotation-revolution ratio to form a spatial extracycloidal path. The rotation of arm wheel 2 202 compensates for the revolution tilt angle, so that the placement surface of the material rack 3 is always horizontal and facing upward. The six to twelve arms realize synchronous multi-station continuous conveying, eliminate intermittent pauses, and effectively improve efficiency. Through the coordinated control of eccentricity and the number of arms, high-density, zero-tilt, and customizable continuous material conveying can be achieved in a limited space.

[0024] To ensure the smooth implementation of this embodiment, it is necessary to understand that each corresponding arm of arm wheel one 201 and arm wheel two 202 is connected by a hinge block 203. A wheel disk 204 is fixed on the side of arm wheel one 201 facing arm wheel two 202. A notch 205 is eccentrically opened on the wheel disk 204. A shaft rod 206 is fixed on the side of arm wheel two 202 facing arm wheel one 201. The shaft rod 206 is locked in the notch 205. The notch 205 can replace the traditional gear or synchronous belt, reduce the transmission backlash, and ensure the synchronization of the rotation and the common speed ratio. The contact surface between the eccentric notch 205 and the shaft rod 206 is curved. The curved surface design can optimize the motion trajectory, reduce the acceleration change of the material rack 3, improve the stability of the material, and the integrated wheel disk 204 and notch 205 structure can avoid the assembly error of multiple parts.

[0025] To ensure the smooth implementation of this embodiment, it is necessary to understand that the material rack 3 includes two coaxial sleeves 301. Both coaxial sleeves 301 are connected to one end of the hinge block 203, and the coaxial sleeves 301 pass through the second arm wheel 202 and are fixed to one end of the hinge block 203. When the second arm wheel 202 revolves around the first arm wheel 201 and rotates on its own axis, the coaxial sleeves 301 act as the axis of rotation, passing through the arm wheel support, so that the material rack 3 and the hinge block 203 form an integrated rigid connection. The through-hole design of the sleeves restricts the swing freedom of the material rack 3, allowing it to rotate only around the sleeve axis; at the same time, the rotation of the second arm wheel 202 drives the sleeves to rotate synchronously through the hinge block 203, and with the tilt angle compensation mechanism in the revolution motion, it is ensured that the placement surface of the material rack 3 is always horizontal.

[0026] To ensure the smooth implementation of this embodiment, it is necessary to understand that each of the two coaxial sleeves 301 has an insert block 302 fixed at one end, and a shelf 303 is inserted between the two insert blocks 302. Limiting components are fixed at both ends of the shelf 303. The limiting components include a sliding sleeve 304, which is fixed to the surface of the shelf 303 by bolts. Three limiting rods 305 are fixed on the top surface of the sliding sleeve 304. The axis connecting the three limiting rods 305 forms an equilateral triangle. The workpiece 8 to be processed includes a steel strip 801. One end of the steel strip 801 is slotted and is limited at one of the limiting rods 305. The other end has a hole and is inserted into one of the limiting rods 305 at the other end.

[0027] To ensure the smooth implementation of this embodiment, it is necessary to understand that the material handling device includes a linear slide 4, which performs vertical stroke movement. A platform is provided on one side of the linear slide 4, which moves linearly through the linear slide 4. At least two pneumatic telescopic tubes 5 are installed on the platform. A top plate 6 is fixed to the top of the pneumatic telescopic tube 5, and a suction cup 7 is fixed to the bottom of the top plate 6. The suction cup 7 is directly opposite the top surface of one of the material racks 3. The linear slide 4 drives the platform to descend vertically to complete coarse positioning and cover the large stroke. The height of the two pneumatic telescopic tubes 5 is independently fine-tuned to compensate for the positional tolerance of the material rack 3 and ensure that the suction cup 7 is in contact with the surface of the material and adsorbs it. After picking up the material, the pneumatic telescopic tube 5 retracts first to avoid obstacles, and the linear slide 4 then rises to reset after the entire stroke.

[0028] To ensure the smooth implementation of this embodiment, it is necessary to understand that, in the initial state, the top surface of each shelf 303 is horizontally facing upward and is horizontal to one side of the hinge block 203. A drive source 9 is installed on one side of one of the supports 1, and the output end of the drive source 9 is coaxially fixed with the arm wheel 201 of one of the eccentric wheel loading and positioning parts 2.

[0029] In summary, in the initial state, the top surface of each shelf 303 is horizontal and faces upwards, maintaining a horizontal position with one side of the hinge block 203. After the device is started, the drive source 9 drives the first arm wheel 201 to rotate. The rotation of the first arm wheel 201 interacts with the shaft 206 of the second arm wheel 202 through the notch 205 on the wheel disk 204, causing the second arm wheel 202 to revolve around the axis of the first arm wheel 201. At the same time, due to the curved surface contact design between the notch 205 and the shaft 206, the second arm wheel 202 also generates a precise rotational motion. This composite motion is based on the principle of planetary gear trains, which causes the hinge block 203 connected to the second arm wheel 202 to drive the shelf 3 to move along the spatial extracycloid path. The revolution of the shelf 3 is driven by the first arm wheel 201, while the rotation of the second arm wheel 202 is precisely controlled through mechanical linkage, ensuring that the placement surface of the shelf 3 always maintains a horizontal posture at any angle of revolution. The sliding sleeves 304 at both ends form an equilateral triangle structure through the limiting rods 305, which is used to limit the steel strip 801 of the workpiece 8 to be processed, ensuring the stability of the material during the conveying process. When the material rack 3 carries the material and rotates to the picking position, the linear slide 4 in the picking device drives the platform to descend vertically to complete the coarse positioning, covering the large stroke. The double pneumatic telescopic tubes 5 independently fine-tune the height to compensate for the positional tolerance of the material rack 3, ensuring that the suction cup 7 adheres to the surface of the material and adsorbs it. After picking up the material, the pneumatic telescopic tube 5 retracts first to avoid obstacles, and the linear slide 4 rises up to reset the entire process. The entire device realizes the continuous and stable conveying of materials through the circumferentially equidistant material rack 3 and the continuous rotation of the eccentric wheel, which improves the production efficiency. Moreover, the circumferential layout of the material rack 3 makes full use of the space and allows for multi-station operation. Through the coordinated control of the eccentricity and the number of support arms, high-density, zero-tilt, and customizable continuous material conveying can be achieved in a limited space.
