Description

Technical Field

[0001] This utility model relates to the field of jig structure, and in particular to a robotic arm flipping clamp jig. Background Technology

[0002] Existing stamped products are generally characterized by their thin and lightweight structure. After stamping, they require multiple subsequent processing steps, often necessitating multiple material flipping operations. Currently, two main methods are used for flipping these thin stamped parts: manual flipping and robotic arms performing multiple gripping and angle adjustments. However, traditional manual operation has significant drawbacks, including low efficiency and the risk of surface scratches or accidental drops. While robotic arm flipping solutions avoid the shortcomings of manual operation, they suffer from inherent disadvantages such as complex system assembly, poor equipment compatibility, cumbersome flipping processes, and difficulties in maintenance and disassembly.

[0003] Addressing the efficiency bottlenecks and implementation difficulties of existing flipping technologies, this technical solution innovatively proposes a dedicated stamping product flipping fixture. While achieving efficient flipping of thin and light products, it also boasts multiple technical advantages: an adjustable structural design to accommodate the processing needs of products with different specifications; optimized mechanical structure to significantly improve the ease of assembly and component replaceability; and a precise flipping action achieved in conjunction with an intelligent control system, effectively reducing equipment usage and maintenance costs while ensuring operational stability. Utility Model Content

[0004] The present invention aims to at least partially solve one of the technical problems in the related technologies. Therefore, the main objective of this invention is to provide a robotic arm flipping fixture, which addresses the problems of low manual efficiency, product damage, poor robotic arm adaptability, and complex structure in the prior art when flipping stamped thin and light products.

[0005] To achieve the above objectives, this utility model provides a robotic arm flipping fixture, comprising a fixture body consisting of a first fixture, a second fixture, and a flipping drive mechanism.

[0006] The first fixture is disposed on one side of the second fixture, and the flipping drive mechanism is connected between the first fixture and the second fixture.

[0007] Both the first fixture and the second fixture include a connecting arm for connection to the flipping drive mechanism, and a bracket connected to one end of the connecting arm. The bracket is provided with various connecting parts, and each connecting part is provided with a gripping head for grasping the product.

[0008] The second fixture flips in cooperation with the flipping drive mechanism to pick up and flip the product from the first fixture.

[0009] As a further embodiment of this utility model, the bracket has a frame structure, and each of the connecting members is disposed on two opposite sides of the frame.

[0010] As a further embodiment of this utility model, the number of connectors is at least 6, with 2 connectors on each of the two opposite sides of the bracket and 1 connector on each of the other opposite sides.

[0011] As a further embodiment of this invention, the connector is connected to the material taking head via a detachable first fastener.

[0012] As a further embodiment of this utility model, the connector has a through hole, the bracket has a connecting part at a corresponding position, and the connector is connected to the connecting part by a second fastener passing through the through hole.

[0013] As a further embodiment of this utility model, the connecting part is a slidable structure within the bracket, and the through hole forms a guide rail structure that can be used for the sliding of the second fastener. The bracket achieves sliding adjustment in two axes through the cooperation of the second fastener, the connecting part, and the through hole.

[0014] As a further improvement of this invention, the material handling head is a suction cup structure.

[0015] As a further embodiment of this utility model, the flipping drive mechanism is a rotating shaft driven by a motor, the first fixture is a fixed fixture fixed to one side of the mounting base of the flipping drive mechanism, and the second fixture is a movable fixture connected to the rotating shaft.

[0016] As a further improvement of this invention, the second fixture can be rotated at a maximum angle of at least 180°.

[0017] The beneficial effects of this utility model are as follows:

[0018] This solution uses a first fixture fixed to one side of the flipping drive mechanism as a reference support. The second fixture is driven by a motor-driven shaft to flip at least 180°, enabling the product to be flipped in both directions in one operation, avoiding the risk of misalignment caused by multiple operations. Both fixtures use a frame structure with two pairs of connecting parts distributed on opposite sides. Through through holes, sliding connections, and a second fastener, the connecting parts can be flexibly adjusted in both horizontal and vertical axes, adapting to products of different sizes and simplifying the disassembly and replacement process of traditional fixtures. A suction cup-type material handling head replaces the mechanical gripper, grasping the product through suction force, avoiding surface damage caused by rigid contact, and is especially suitable for thin and light stamped parts. The flipping drive mechanism requires only a single motor to control the shaft, significantly reducing equipment complexity and maintenance costs compared to multi-axis robots. While improving flipping efficiency, it reduces product wear and equipment downtime, meeting the needs of high-frequency, multi-specification stamping processing. Attached Figure Description

[0029] as follows:

[0030] Please see the appendix Figure 1-7 ,

[0031] The main structure includes a fixture body 1) consisting of a first fixture 10), a second fixture 11), and a flipping drive mechanism 12). The first fixture 10 is disposed on one side of the second fixture 11), and the flipping drive mechanism 12 is connected between the first fixture 10 and the second fixture 11. Both the first fixture 10 and the second fixture 11) include a connecting arm 110 for connecting with the flipping drive mechanism 12) and a bracket 111 connected to one end of the connecting arm 110). Each bracket 111 is provided with a connecting member 112, and the connecting member 112 is provided with a picking head 113 for gripping the product. The second fixture 11 flips by cooperating with the flipping drive mechanism 12, so as to realize the gripping and flipping of the product from the first fixture 10.

[0032] The working principle is as follows:

[0033] This technical solution effectively solves the problems of low manual efficiency and product damage during the existing stamping product turning process.

[0034] The problem of poor adaptability of robotic arms. Traditional manual flipping relies on manual operation, which is not only inefficient but also prone to scratching or dropping the product surface. While robotic arm solutions replace manual labor, they suffer from drawbacks such as complex structure, insufficient adaptability, and cumbersome maintenance. This solution uses a fixture body 1 composed of a first fixture 10, a second fixture 11, and a flipping drive mechanism 12 to achieve efficient flipping. The first fixture 10 is fixed to one side of the flipping drive mechanism 12, and the second fixture 11 is linked to the rotating shaft of the flipping drive mechanism 12 through a connecting arm 110, which can complete at least 180° flipping under motor drive to accurately grasp and transfer products. The brackets 111 of both fixtures adopt a frame structure and are provided with at least 6 connectors 112 on both sides. They are connected to the suction cup type picking head 113 through detachable first fasteners 1121, which can adapt to products of different specifications and avoid the rigid contact damage to products caused by traditional robotic arms. Furthermore, the connector 112 and the bracket 111 are connected via a through hole 1120 and a sliding connecting part 1123, and a two-axis sliding adjustment is achieved using a second fastener 1122, significantly improving the fixture's flexibility, assembly efficiency, and adaptability. The flipping drive mechanism 12 simplifies the multi-axis control requirements of traditional robotic arms, enabling stable flipping actions to be completed with a single motor driving the rotating shaft. This reduces equipment complexity and maintenance costs, making it suitable for high-frequency flipping scenarios of thin and light stamped parts. While improving production efficiency, it minimizes product damage and equipment downtime.

[0035] The assembly and disassembly process can be,

[0036] During assembly, fix the motor-driven shaft to the mounting base, ensuring the shaft is horizontally aligned with the base. Connect the power supply and control lines. Connect the first fixture 10 to the fixed side of the mounting base of the tilting drive mechanism 12 via the connecting arm 110, and tighten with bolts. Ensure the bracket 111 has a frame structure and is perpendicular to the base. Connect the connecting arm 110 of the second fixture 11 to the shaft end of the tilting drive mechanism 12, and fix it via the shaft linkage structure. Adjust the position of the movable fixture to maintain its initial parallel state with the first fixture 10. (The last sentence appears to be incomplete and possibly refers to a separate process.) At least six connectors 112 are installed on each of the two opposite sides, two on each of the two opposite sides and one on each of the other opposite sides. The connectors 112 are passed through the through holes 1120 on the bracket 111 by the second fasteners 1122, and their positions are adjusted by the sliding guide rails of the connecting part 1123. After locking, it is ensured that the connectors 112 can be flexibly adjusted along the two axes. The suction cup type picking head 113 is fixed to the end of the connector 112 by the detachable first fastener 1121, such as a quick-release bolt. The flatness and suction force of the contact surface between the suction cup and the product are checked. The device is then powered on and flipped.

[0037] The drive mechanism 12 controls the second fixture 11 to rotate at least 180°, verifies the continuity of the gripping, flipping and releasing actions of the pick-up head 113, and fine-tunes the position of the connector 112 to fit the product size.

[0038] During disassembly, replacement, and maintenance, disconnect the power supply to the flipping drive mechanism 12, clean any residual products from the fixture surface, ensure a safe operating environment, loosen the first fastener 1121, and sequentially remove the suction cup-type material handling heads 113 from each connector 112, classify and store them, loosen the second fastener 1122, slide the connector 112 on the bracket 111 along the guide rail, and carefully record the original position of each connector 112 for subsequent reassembly, remove the fixing bolts between the rotating shaft and the connecting arm 110 of the second fixture 11, remove the movable fixture from the flipping drive mechanism 12 as a whole, remove the connecting bolts between the first fixture 10 and the mounting base, separate the fixed fixture from the flipping drive mechanism 12, remove the transmission components of the motor and the rotating shaft, and disassemble the rotating shaft support structure and base fixing components in sequence to complete the complete disassembly.

[0039] Reference Appendix Figure 6 In a preferred embodiment of this utility model, the bracket 111 has a frame structure, and each connecting piece 112 is disposed on two opposite sides of the frame.

[0040] In this technical solution, the support 111 adopts a frame structure with connectors 112 arranged on both sides. This not only enhances the overall stability through the rigid support of the frame, but also evenly distributes the gripping force using the symmetrically distributed connectors 112, preventing product deformation caused by unilateral force. The dual-sided layout also facilitates flexible adjustment of the material handling head 113 position according to the product size, ensuring that stamped parts of different specifications can be firmly adsorbed, while reducing vibration and displacement caused by the rotation of the support 111.

[0041] Reference Appendix Figure 6 In a preferred embodiment of this utility model, the number of connectors 112 is at least 6, with 2 connectors on each of two opposite sides of the bracket 111 and 1 connector on each of the other opposite sides.

[0042] The bracket 111 can be a rectangle with two connectors 112 facing outward on each of its two sides, and one connector 112 facing inward on each of its other two sides, which can increase the absorption surface of the product.

[0043] Reference Appendix Figure 7 In a preferred embodiment of this utility model, the connector 112 is connected to the material take-up head 113 via a detachable first fastener 1121.

[0044] The material handling head 113 can be replaced according to different product specifications. When replacing it, the first fastener 1121 should be removed.

[0045] Reference Appendix Figure 7 In a preferred embodiment of this utility model: the connector 112 has a through hole 1120, and the bracket 111

[0046] A connecting part 1123 is provided at the corresponding position, and the connecting piece 112 is connected to the connecting part 1123 through the through hole 1120 via the second fastener 1122.

[0047] A through hole 1120 is provided on the connector 112, which, together with the connecting part 1123 on the bracket 111 and the second fastener 1122, enables the connector 112 to be quickly positioned and adjustablely fixed. The cooperation between the through hole 1120 and the fastener allows the connector 112 to slide along the bracket 111 to adapt to different product sizes, and also ensures stability by locking after adjustment. This simplifies the assembly process, facilitates disassembly and maintenance, and avoids the irreversible adjustment problems caused by welding or riveting in traditional fixing methods.

[0048] Reference Appendix Figure 7 In a preferred embodiment of this utility model, the connecting part 1123 is a slidable structure inside the bracket 111, and the through hole 1120 forms a guide rail structure that can be used for the sliding of the second fastener 1122. The bracket 111 achieves sliding adjustment in two axes through the cooperation of the second fastener 1122, the connecting part 1123, and the through hole 1120.

[0049] This technical solution designs the connecting part 1123 as a sliding structure within the bracket 111, and combines it with the guide rail formed by the through hole 1120, allowing the second fastener 1122 to move freely within the guide rail, thus achieving flexible adjustment of the connecting part 112 in both horizontal and vertical directions. During operation, simply loosen the fastener, slide the connecting part 112 along the guide rail to the target position, and then re-tighten it. This design can precisely adapt to the gripping needs of products of different sizes, ensuring stability after adjustment. This design avoids the cumbersome steps of repeatedly disassembling or replacing parts required by traditional fixtures, significantly improving assembly efficiency and equipment versatility.

[0050] Reference Appendix Figure 6-7 In a preferred embodiment of this utility model, the material handling head 113 is a suction cup structure.

[0051] The suction cup-type gripping head 113 uses suction force to grasp stamped parts, avoiding scratches or deformation caused by traditional mechanical grippers. The suction cup can adapt to product surfaces of different shapes and sizes, ensuring a stable grip while reducing the risk of damage to thin parts, improving operational safety and compatibility with products of different specifications.

[0052] Reference Appendix Figure 5 In a preferred embodiment of this utility model: the flipping drive mechanism 12 is a rotating shaft driven by a motor, the first fixture 10 is a fixed fixture fixed to one side of the mounting base of the flipping drive mechanism 12, and the second fixture 11 is a movable fixture connected to the rotating shaft.

[0053] The movable fixture 11 is rotated by a motor-driven shaft, while the fixed fixture 10 is mounted on one side of the shaft base as a reference support. The movable fixture rotates with the shaft to grasp and flip the product.

[0054] The rotating motion and the fixed fixture provide a stable gripping starting point. The two work together to ensure a smooth and efficient flipping process. A single motor is all that is needed to complete the precise flipping, reducing equipment complexity and maintenance costs, while also adapting to the processing needs of products of different specifications.

[0055] Reference Appendix Figure 1-5 In a preferred embodiment of this utility model, the second fixture 11 can be rotated at a maximum angle of at least 180°.

[0056] The second fixture 11 can be rotated at least 180°, allowing the product to be completely reversed in one operation. This avoids mid-process adjustments or multiple operations, simplifies the processing flow, improves efficiency, and reduces the risk of product displacement or surface damage caused by multiple rotations. It is especially suitable for processes requiring double-sided processing or precise reversal. The large-angle rotation ensures that products of different specifications can be rotated stably.

Any equivalent structural transformations made using the contents of the present utility model specification and drawings under the concept of the present utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
