Description

Technical Field

[0001] This utility model relates to the field of mechanical feeding technology, specifically a clamping device for cyclic feeding. Background Technology

[0002] In automated production's cyclic material feeding process, traditional single-clamp structures suffer from long cycle times and low efficiency, making it difficult to meet high-capacity requirements. While multiple clamps can work collaboratively, their intersecting motion paths often lead to interference, necessitating significant clearance and increasing equipment footprint. Furthermore, the fixed angles of ordinary clamps prevent adjustment to different workstation needs, increasing the risk of material misalignment or surface damage, requiring frequent manual intervention and disrupting production stability. Therefore, there is an urgent need for a cyclic material feeding device that enables efficient coordination of multiple clamps, a compact layout, and flexible adaptation to different operating angles.

[0003] Therefore, there is an urgent need for a clamping device with a circulating feeding mechanism to solve the above problems. Utility Model Content

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0040] In one embodiment of this utility model, such as Figure 1-5 As shown, a clamping device for cyclic feeding is provided, including: a working surface 4, an upper clamp 5, and a lower clamp 6. The upper clamp 5 is disposed above the lower clamp 6, and the upper clamp 5 and the lower clamp 6 repeatedly move towards the working surface 4. The movement trajectories of the upper clamp 5 and the lower clamp 6 are parallel. The lower clamp 6 can rise and fall along its own movement trajectory to descend and avoid the upper clamp 5, or rise to the same height position as the upper clamp 5.

[0041] This utility model provides a clamping device for cyclic feeding. The parallel movement trajectory of the upper and lower clamps 6 ensures stable transfer process and avoids material deviation. The lifting function of the lower clamp 6 enables stable feeding of the two clamps and allows them to operate in a staggered manner in a limited space. This reduces the equipment footprint and enables an alternating transfer mode, thereby forming a continuous workflow, improving clamp feeding efficiency, effectively reducing the frequency of manual intervention, and improving the consistency of production cycle.

[0042] Preferably, both the upper clamp 5 and the lower clamp 6 include a rotating source 701 and a suction cup 702. The rotating sources 701 of the upper clamp 5 and the lower clamp 6 repeatedly move towards the working surface 4 along their parallel motion trajectories. The suction cup 702 is located at the rotation output end of the rotating source 701 and is used to move synchronously with the corresponding rotating source 701, and can rotate to a specific angle as needed. The rotating source 701 and the suction cup 702 work together with the upper and lower clamps 6 to move independently along parallel trajectories, effectively improving loading efficiency and automation. By setting the rotating source 701 and the suction cup 702, each suction cup 702 can move synchronously with the corresponding rotating source 701 and can also independently adjust its angle, flexibly adapting to the needs of different workstations. At the same time, the suction cup 702 uses an adsorption method to quickly grasp the workpiece, effectively avoiding mechanical damage to the workpiece surface.

[0043] The clamping device for cyclic feeding further includes an upper drive assembly 9 and a lower drive assembly 10, which are stacked vertically along the mechanical feeding axis. They drive the upper clamp 5 and lower clamp 6 to reciprocate independently along the mechanical feeding axis, resulting in a compact structure and high space utilization. The lower drive assembly 10 is located inside the upper drive assembly 9 and at its bottom. The upper and lower drive assemblies 10 do not interfere with each other, improving the stability and synchronization of clamp operation. Simultaneously, the output end of the upper drive assembly 9 is connected to the upper clamp 5, and the output end of the lower drive assembly 10 is connected to the lower clamp 6. The upper drive assembly 9 and lower drive assembly 10 drive the upper clamp 5 and lower clamp 6 to reciprocate linearly along the mechanical feeding axis, respectively. The two clamps can be individually controlled in terms of movement rhythm and path according to process requirements, enhancing operational flexibility and effectively improving feeding efficiency and automation levels.

[0044] Preferably, both the upper drive assembly 9 and the lower drive assembly 10 include: a horizontal guide rail 112 arranged along the mechanical feeding axis, a horizontal slider 113 slidably engaged with the horizontal guide rail 112, a horizontal drive source 111, and a horizontal lead screw 114. The horizontal lead screw 114 is parallel to the horizontal guide rail 112 and connected to the corresponding horizontal slider 113; the horizontal drive source 111 is connected to the horizontal lead screw 114 and is used to drive the horizontal lead screw 114 to rotate. The horizontal slider 113 of the upper drive assembly 9 is connected to the upper clamp 5, and the horizontal slider 113 of the lower drive assembly 10 is connected to the lower clamp 6. The two drive assemblies, by driving the horizontal lead screw 114 to rotate, independently drive the corresponding horizontal slider 113 to reciprocate linearly along the horizontal guide rail 112, thereby driving the upper clamp 5 and the lower clamp 6 to move along the mechanical feeding axis.

[0045] The upper clamp 5 and lower clamp 6 achieve precise reciprocating motion along the mechanical loading axis through the cooperation of the horizontal guide rail 112, slider, lead screw, and drive source. This structure provides smooth transmission and high positioning accuracy, enhancing the stability and repeatability of clamp operation. The upper and lower drive components 10 are independently controlled and do not interfere with each other, improving the flexibility and adaptability of use. At the same time, the lead screw drive can effectively bear heavy loads and extend the service life of the equipment.

[0046] The clamping device for the cyclic feeding also includes a lifting assembly 12, which allows the lower clamp 6 to move up and down along the Z-axis in the mechanical feeding shaft's trajectory. This enables it to work collaboratively with the upper clamp 5 at the same height or to descend and avoid obstacles when not needed, effectively improving the coordination of movements between the upper and lower clamps 6 and the space utilization rate. The lifting assembly 12 is positioned between the horizontal slider 113 of the lower drive assembly 10 and the lower clamp 6, and the lower clamp 6 is mounted on the output end of the lifting assembly 12. By setting up the lifting assembly 12, motion interference between the clamps is effectively avoided, improving the stability and automation level of the feeding process.

[0047] Specifically, the lifting assembly 12, mounted on the horizontal slider 113 of the lower drive assembly 10, includes a longitudinal guide rail 132 arranged along the Z-axis, a longitudinal slider 133 slidably engaged with the longitudinal guide rail 132, a longitudinal drive source 131, and a longitudinal lead screw 134. The longitudinal lead screw 134 is parallel to the longitudinal guide rail 132 and connected to the longitudinal slider 133. The longitudinal drive source 131 is connected to the longitudinal lead screw 134. By driving the longitudinal lead screw 134 to rotate, the longitudinal slider 133 reciprocates linearly along the longitudinal guide rail 132, thereby causing the lower clamp 6 to move along the Z-axis.

[0048] The clamping device for the circulating feeding also includes a workbench 1, with a working surface 4 arranged on the workbench 1. The workbench 1 is used to install the upper clamp 5 and the lower clamp 6, providing a stable support foundation for the entire clamp.

[0049] Specifically, a slotted guide rail 3 is provided in the middle of the workbench 1. The edge of the slotted guide rail 3 is connected to the workbench 1 by a step 2. The slotted guide rail 3 allows the lower clamp 6 to be precisely guided along the slotted guide rail 3 during movement, and to avoid positional conflict with the upper clamp 5 through the step 2 area.

[0050] In this embodiment, the upper drive component 9 and the lower drive component 10 are arranged side by side and stacked vertically to save installation space.

[0051] In this embodiment, the upper drive assembly 9 is installed above the top of the worktable 1 and extends along the direction of the mechanical feeding shaft. Its slider is connected to the upper clamp 5 and is used to drive the upper clamp 5 to reciprocate along the mechanical feeding shaft.

[0052] The lower drive assembly 10 is installed on the step 2 of the worktable 1, and the output end of the lower drive assembly 10 slides along the slotted guide rail 3 and is located inside the upper drive assembly 9. It is also arranged along the mechanical feeding shaft. Its slider is connected to the lower clamp 6 through the lifting assembly 12 to realize the Z-axis lifting movement of the lower clamp 6 based on the movement of the mechanical feeding shaft.

[0053] Preferably, mounting plates 8 are installed on the horizontal slider 113 and the vertical slider 133. The mounting plates 8 are used to install the upper clamp 5 and the lower clamp 6, making the connection between the clamp and the drive component more stable and reliable.

[0054] More preferably, the clamping device for the cyclic feeding also includes a drag chain 14, which is connected to the side of the horizontal slider 113. The drag chain 14 is used to assist the upper clamp 5 in sliding.

[0055] The operating principle of this embodiment is as follows: During operation, the horizontal drive source 111 of the upper drive assembly 9 drives the horizontal lead screw 114 to rotate, which in turn drives the horizontal slider 113 to move along the horizontal guide rail 112 along the mechanical feeding axis to the working surface 4. The rotation source 701 of the upper clamp 5 drives the suction cup 702 to rotate to the appropriate angle. After the suction cup 702 adsorbs the workpiece under negative pressure, it moves to the working surface 4 with the upper clamp 5 to complete the feeding. At the same time, the lower drive assembly 10 drives the lower clamp 6 to move synchronously along the slotted guide rail 3 of the worktable 1 along the mechanical feeding axis. The lifting assembly 12 drives the longitudinal slider 133 to descend along the longitudinal guide rail 132 through the longitudinal drive source 131, so that the lower clamp 6 is lower than the upper clamp 5 to avoid the movement trajectory and avoid interference.

[0056] When the upper clamp 5 completes the loading and returns, the lower clamp 6 rises to the same height as the upper clamp 5 under the drive of the lifting component 12. Its rotation source 701 adjusts the angle of the suction cup 702 to adsorb the new workpiece, which is then driven by the lower drive component 10 to be transferred to the working surface 4, thus realizing alternating loading.

[0057] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
