Description
TECHNICAL FIELD
[0001] The utility model relates to automatic technology field especially, be related to an automatic feeding device. BACKGROUND
[0002] In modern industrial production, the feeding link of materials is a key component of many production processes. The traditional operation mode usually adopts the mode that a mechanical arm can only clamp one material at a time to carry out feeding operation.
[0003] This way has many shortcomings. First, its operation efficiency is relatively low, which cannot meet the urgent need for efficient feeding in the current production process. In the face of a large number of materials that need to be fed, the mechanical arm frequently carries out the actions of grabbing, transferring and placing a single material, which consumes a lot of time and seriously restricts the efficiency of the whole production process.
[0004] Secondly, the mechanical arm has a heavy workload in this frequent single operation mode. Long-term high-intensity repetitive motion makes the components of the mechanical arm prone to wear and failure, not only increasing the maintenance cost of the equipment, but also possibly causing production interruption due to equipment failure, affecting the continuity and stability of production. At the same time, since the mechanical arm needs to be constantly operated, it also causes unnecessary energy consumption, which undoubtedly increases the production cost of the enterprise in the long run.
[0005] In addition, in the face of complex production scenarios where the distance between materials on the tray is small and the distance between materials on the conveying line needs to be kept large, the traditional operation mode is difficult to adapt flexibly. It cannot clamp multiple materials at a time to meet the case where the distance between materials on the tray is small, and it cannot conveniently adjust the distance between materials before placing the materials on the conveying line to meet the placement requirements of the conveying line, which makes the whole feeding process more cumbersome and prone to problems such as uneven placement of materials and non-compliance with production requirements, thereby affecting the subsequent production process.

[0018] a plurality of sliding blocks in sliding connection with the two sliding rails, and the plurality of movable clamping jaws are in one-to-one fastening connection with the plurality of sliding blocks;
[0019] a fixed block fastened to the position of the mounting plate corresponding to the fixed clamping jaw;
[0020] a first connecting rod hingedly connected to the top of the fixed block at the middle of the rod body;
[0021] a plurality of second connecting rods, each of which is in one-to-one correspondence with a sliding block, and the middle of the rod body of the second connecting rod is hingedly connected to the top of the corresponding sliding block;
[0022] wherein the two ends of the first connecting rod are hingedly connected to the adjacent second connecting rods on both sides thereof, and one end of each of the two adjacent second connecting rods is hingedly connected;
[0023] a telescopic rod arranged above the first connecting rod and crossing the first connecting rod, and the two ends of the telescopic rod are hingedly connected to one end of the adjacent two second connecting rods; the telescopic rod drives the first connecting rod and the second connecting rod to deflect, so that the movable clamping jaws move away from or close to the fixed clamping jaw along the sliding rails.
[0024] Preferably, the fixed clamping jaw and the movable clamping jaw are each provided with a first rotating seat driven by a motor.
[0025] Preferably, the mounting seat is fastened to the execution end of the mechanical arm through a flange.
[0026] Preferably, the plate surface of the mounting seat is provided with a weight-reducing groove.
[0027] Preferably, a second rotating seat driven by a motor is arranged between the mounting seat and the execution end of the mechanical arm.
[0028] Due to the adoption of the technical scheme as described above, the utility model has the following beneficial effects:
[0029] The utility model discloses simple structure, through the drive mechanism control the spacing between movable clamp jaw and fixed clamp jaw flexible adjustment, can take a plurality of materials once, especially applicable to the scene of smaller material spacing on the tray.Compared with the mode of traditional mechanical arm single -time clamping one material, the reciprocating action number of mechanical arm is reduced significantly, and the efficiency of feeding operation is greatly improved.In actual production, this efficiency improvement can be directly converted into the increase of production capacity, and the demand of large -scale production is met.
[0030] Since single operation can handle multiple materials, the operation frequency of the mechanical arm is greatly reduced. This not only reduces the wear and tear of each joint of the mechanical arm, prolongs its service life, but also reduces the energy consumption of the equipment. In the long run, this energy consumption optimization can save operating costs for enterprises, while reducing the frequency and cost of equipment maintenance.
[0031] The telescopic rod and the connecting rod system of the drive mechanism are designed to enable the movable clamp jaw to approach or move away from the fixed clamp jaw synchronously, and to accurately adapt to the material placement requirements of different spacings. In the conveying line scene, the material placement specification can be met by adjusting the spacing between the clamp jaws, avoiding secondary adjustment and simplifying the production process.
[0032] At the same time, the synchronous action mechanism of the connecting rod system ensures that the displacement distances of all movable clamp jaws are equal, avoiding collision or skewing of the materials during clamping or releasing, and significantly improving the reliability of the feeding process and the neatness of the material placement. By adding a motor-driven rotary seat, the device has the ability to adjust the rotation of the clamp jaw and rotate the overall space. This enables the device to adapt to complex production scenarios that have specific requirements for the direction of the materials, significantly improving the versatility and operation flexibility of the equipment.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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.

[0043] Example 1:
[0044] Combined with appendix Figs. 1-6 An automatic feeding device includes a robotic arm 1, a mounting base 2, and a mounting plate 3. The mounting base 2 is mounted on the actuating end of the robotic arm 1, and the movement of the robotic arm 1 drives the mounting base 2 to move accordingly. The mounting plate 3 is positioned at a certain interval on the side of the mounting base 2 facing away from the robotic arm 1. Specifically, connecting posts 4 are installed at both ends of the mounting base 2. It is through the connecting posts 4 that the mounting plate 3 and the mounting base 2 are securely connected, and a certain cavity structure is constructed between the mounting plate 3 and the mounting base 2.
[0045] A fixed gripper 5 is mounted at the center of the mounting plate 3. On either side of the fixed gripper 5, multiple movable grippers 6 are symmetrically distributed. Notably, a drive mechanism 7 is housed within the cavity formed between the mounting plate 3 and the mounting base 2. Its core function is to drive the movable grippers 6 to move synchronously closer to or further away from the fixed gripper 5. Simultaneously, slots are provided on the mounting plate 3 at locations corresponding to the movable grippers 6. This design facilitates a precise and effective connection between the movable grippers 6 and the drive mechanism 7.
[0046] Considering the often small spacing between materials on pallets in actual production scenarios, when materials need to be gripped, the drive mechanism 7 can drive the movable gripper 6 to move closer to the fixed gripper 5. The key to this process is that it allows the distance between the movable gripper 6 and the fixed gripper 5 to flexibly adapt to the small spacing of the materials on the pallet, thus achieving efficient operation of gripping multiple materials simultaneously. This significantly improves overall work efficiency. After gripping the materials, precise control of the robotic arm 1 allows the materials to be smoothly transferred to the conveyor line.
[0047] However, materials placed on conveyor lines typically require a large spacing. Therefore, before placing materials on the conveyor line, the drive mechanism 7 can again drive the movable gripper 6 to move away from the fixed gripper 5, thereby increasing the spacing between adjacent materials to meet the conveyor line's placement requirements before placement. Compared to traditional methods where the robotic arm 1 can only grip one material at a time, this automatic feeding device significantly improves feeding efficiency while effectively reducing the workload of the robotic arm 1, thus reducing energy consumption. In the long run, it can also extend the service life of the robotic arm 1 and reduce equipment maintenance costs.
[0048] Regarding the specific structure of the drive mechanism 7, it mainly includes a slide rail 7-1, a slider 7-2, a first connecting rod 7-4, and multiple second connecting rods 7-5. There are two slide rails 7-1, respectively located on both sides of the corresponding slots on the mounting plate 3. Matching these two slide rails 7-1 are multiple sliders 7-2, which can slide smoothly along the slide rails 7-1, and each movable gripper 6 is securely connected to one slider 7-2 in a one-to-one correspondence. It must be emphasized here that the connection between the slider 7-2 and the slide rail 7-1 must ensure smooth and unobstructed movement, preventing any jamming. Furthermore, the slide rail 7-1 and slider 7-2 are assembled using a dovetail structure. This design effectively prevents the slider 7-2 from accidentally detaching from the slide rail 7-1, thus ensuring the stable operation of the device.
[0049] A fixing block 7-3 is securely connected to the mounting plate 3 at the position corresponding to the fixing claw 5. The fixing block 7-3 has a clear function: to provide a mounting surface at the same height as the slider 7-2 for subsequent installation, ensuring that all components are at the same level and laying the foundation for coordinated operation.
[0050] The middle of the first link 7-4 is precisely hinged to the top of the fixed block 7-3. Simultaneously, multiple second links 7-5 correspond one-to-one with multiple sliders 7-2, specifically, the middle of the second link 7-5 is hinged to the top of the corresponding slider 7-2. Furthermore, both ends of the first link 7-4 are hinged to adjacent second links 7-5 on either side. Additionally, adjacent second links 7-5 are also hinged at one end, enabling the entire linkage system to form a coherent and coordinated linkage structure.
[0051] Above the first connecting rod 7-4, a telescopic rod 7-6 is installed, and the telescopic rod 7-6 is arranged in a cross configuration with the first connecting rod 7-4. It is important to note that a gap is left between the telescopic rod 7-6 and the first connecting rod 7-4 to prevent mutual interference. Both ends of the telescopic rod 7-6 are hinged to one end of each of the two adjacent second connecting rods 7-5. When the telescopic rod 7-6 extends or retracts, it drives the first connecting rod 7-4 and the second connecting rod 7-5 to deflect, thereby causing the movable gripper 6 to move along the slide rail 7-1, moving away from or towards the fixed gripper 5. Specifically, when the telescopic rod 7-6 is extended, the first connecting rod 7-4 and the second connecting rod 7-5 gradually deflect towards a straight line. During this process, the second connecting rod 7-5 pulls the corresponding movable gripper 6, causing it to move away from the fixed gripper 5 along the slide rail 7-1, thus increasing the distance between the materials.
[0052] Conversely, when the telescopic rod 7-6 is shortened, the first link 7-4 and the second link 7-5 gradually deflect in a zigzag pattern. At this time, the second link 7-5 drives the movable gripper 6 to move along the slide rail 7-1 closer to the fixed gripper 5, in order to adapt to scenarios where the material spacing is small. Throughout the entire operation, because the movable gripper 6 is restricted by the second link 7-5, and all the second links 7-5 can move synchronously, this ensures that the movable gripper 6 can also achieve synchronous movement, and the displacement distance of each movable gripper 6 is equal. This effectively ensures the neatness of the feeding process, avoids the problem of materials colliding with each other or being misplaced, and further improves the reliability and practicality of the automatic feeding device.
[0053] Example 2:
[0054] Combined with appendix Figs. 2-3An automatic feeding device differs from Embodiment 1 in that, based on Embodiment 1, a first rotating seat 8 driven by a motor is added to both the fixed gripper 5 and the movable gripper 6. Specifically, the fixed gripper 5 is rotatably connected to the mounting plate 3 via the first rotating seat 8; similarly, the movable gripper 6 is also rotatably connected to the slider 7-2 via the first rotating seat 8. In this way, after the material is gripped, the first rotating seat 8 can be precisely controlled to rotate, thereby causing the gripped material to rotate by a certain angle. This improvement gives the automatic feeding device a more flexible feeding capability, enabling it to better adapt to the feeding needs of different scenarios, especially in production processes with specific requirements for material orientation, significantly improving operational convenience and efficiency.
[0055] Furthermore, a second rotating seat, driven by a motor (not explicitly shown in the illustration), is installed between the mounting base 2 and the actuator of the robotic arm 1. This design enables the entire automatic feeding device to rotate as a whole; that is, the automatic feeding device can be rotated and adjusted in space through the driving action of the second rotating seat. This added functionality further enhances the flexibility of the feeding action, broadens the application range of the device, and allows it to complete feeding tasks freely in more complex production layouts.
[0056] In terms of installation details, the mounting base 2 is securely connected to the actuator of the robotic arm 1 via flange 9. The advantage of this connection method is that it not only ensures convenient and quick installation but also achieves precise positioning, ensuring the stability and reliability of the device during operation. Furthermore, weight-reduction grooves are provided on the surface of the mounting base 2. This seemingly simple design detail plays a crucial role—by rationally removing some material, the overall weight of the device is effectively reduced. In practical applications, this weight-reduction measure directly improves the load-bearing capacity of the robotic arm 1, enabling it to handle more or heavier material loading tasks while maintaining its own operational efficiency, thereby enhancing the overall operational capacity and efficiency of the production system to a certain extent.
[0057] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
