Description

Technical Field

[0001] This utility model relates to the field of vacuum furnace feeding technology, and in particular to a vacuum furnace feeding mechanism. Background Technology

[0002] The vacuum furnace loading mechanism is used to transport materials to be processed into the vacuum furnace. Traditionally, when using forklifts and cranes for loading, these tools are primarily used for material handling and lifting, resulting in low operational precision. This makes high-precision positioning difficult when loading vacuum furnaces. Operators often rely on visual observation and experience to judge the material's position and angle, making precise control of material movement difficult and prone to deviations. Furthermore, the working environment of vacuum furnaces is often less than ideal; for example, in foundry workshops, insufficient lighting and excessive dust severely impair the operator's vision, making it difficult to clearly observe the material and the feed inlet position. This further exacerbates the difficulty of alignment, leading to frequent alignment problems during loading and impacting production efficiency and safety. Utility Model Content

[0003] The purpose of this invention is to address the problem that traditional forklifts and cranes are used as the feeding mechanism for vacuum furnaces, but due to their low docking accuracy with the vacuum furnace and the limitation of manual observation in poor environments, alignment is difficult, affecting production efficiency and safety. Therefore, a vacuum furnace feeding mechanism is proposed.

[0004] The technical solution of this utility model is as follows: a vacuum furnace feeding mechanism, including a vacuum furnace, and further including: a feeding trolley disposed at the end of the vacuum furnace, a pair of vacuum furnace feeding rails provided inside the vacuum furnace, a pair of feeding trolley guide rails corresponding to the vacuum furnace feeding rails connected to the top of the feeding trolley via a connecting column, and sliding grooves provided in both the feeding trolley guide rails and the vacuum furnace feeding rails; a sliding mechanism connected to the top of the feeding trolley to allow the feeding basket assembly to enter and exit the vacuum furnace; and a docking mechanism installed on the feeding trolley and the vision robotic arm to accurately connect the feeding trolley and the vacuum furnace feeding rails.

[0005] Optionally, the docking mechanism includes a pair of clamping blocks fixedly connected to the outer wall of the end of the vacuum furnace feeding rail. The outer wall of the end of the feeding car guide rail near the vacuum furnace feeding rail is fixedly connected with wedge-shaped inserts inserted into the corresponding clamping blocks. A pair of guide blocks are fixedly connected to the outer wall of one end of the vacuum furnace. The end of the guide blocks away from the vacuum furnace is provided with a guide surface. A high-intensity indicator light is also fixedly connected to the outer wall of the end of the guide blocks away from the vacuum furnace.

[0006] Optionally, the pair of guide blocks, guide surfaces, and high-intensity indicator lights are all symmetrically arranged with the visual robotic arm base as the center.

[0007] Optionally, the sliding mechanism includes a pair of feeding frames that are slidably connected inside the feeding carriage guide rail to support the loading basket assembly. The feeding frames have feeding frame grooves, and the feeding frame grooves are provided with loading basket support frames that support the loading basket assembly. A robotic arm base plate is fixedly connected inside the feeding carriage. A vision robotic arm is fixedly connected to the upper surface of one end of the robotic arm base plate. The vision robotic arm is provided with gripping claws for grasping the loading basket assembly, and the vision robotic arm is also provided with a vision system.

[0008] Optionally, one end of the wedge-shaped insert inserted into the clamp is fixedly connected to a three-prong plug.

[0009] Optionally, the feeding basket assembly includes a feeding basket, the inside of which is provided with a baffle.

[0010] Optionally, a handrail is fixedly connected to the top outer wall of the feeding cart.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This utility model utilizes the coordinated structure of a feeding cart, a vacuum furnace loading rail, a feeding cart guide rail, a chute, a sliding mechanism, and a docking mechanism to achieve efficient and precise docking with the vacuum furnace even in dusty and low-visibility environments. This reduces loading time, improves production pace, ensures accurate material addition, and stabilizes product quality. Furthermore, it avoids equipment collisions, reduces safety risks, prevents material leakage to reduce environmental pollution, and lowers the difficulty and intensity of work for operators in harsh environments, improving work comfort.

[0026] Example

[0027] like Figures 1 to 6 As shown, the vacuum furnace feeding mechanism proposed in this utility model includes a vacuum furnace 6. A feeding trolley 4 is provided at the end of the vacuum furnace 6. A handle 19 is fixedly connected to the top outer wall of the feeding trolley 4. The handle 19 facilitates pushing the feeding trolley 4 and controlling its direction of movement. A pair of vacuum furnace feeding rails 11 are provided inside the vacuum furnace 6. A pair of feeding trolley guide rails 2 corresponding to the vacuum furnace feeding rails 11 are connected to the top of the feeding trolley 4 through a connecting column 13. Both the feeding trolley guide rails 2 and the vacuum furnace feeding rails 11 are provided with sliding grooves 7.

[0028] Among them, such as Figures 1 to 3 As shown, the feeding trolley 4 and the vision robotic arm 1 are equipped with a docking mechanism that enables precise connection between the feeding trolley 4 and the vacuum furnace loading rail 11. The docking mechanism includes a pair of clamping blocks 17 fixedly connected to the outer wall of the end of the vacuum furnace loading rail 11. The outer wall of the feeding trolley guide rail 2 near the vacuum furnace loading rail 11 is fixedly connected with wedge-shaped inserts 12 that are inserted into the corresponding clamping blocks 17. A pair of guide blocks 61 are fixedly connected to the outer wall of one end of the vacuum furnace 6. The guide blocks 61 away from the vacuum furnace 6 are provided with guide surfaces 62. A high-intensity indicator light 63 is also fixedly connected to the outer wall of the guide blocks 61 away from the vacuum furnace 6. The pair of guide blocks 61, the guide surfaces 62 and the high-intensity indicator light 63 are all symmetrically arranged with the base of the vision robotic arm 1 as the center.

[0029] Secondly, such as Figures 1 to 3 As shown, the top of the feeding trolley 4 is connected to a sliding mechanism that allows the loading basket assembly 8 to enter and exit the vacuum furnace 6. The sliding mechanism includes a pair of feeding racks 5 that are slidably connected inside the feeding trolley guide rail 2 and support the loading basket assembly 8. The feeding racks 5 are equipped with sliders that engage in sliding grooves 7. The function of the sliders is to ensure that the feeding racks 5 can slide smoothly on the feeding trolley guide rail 2 and the vacuum furnace loading rail 11 after docking. The feeding racks 5 are provided with feeding rack grooves 10, which are used to hold the loading basket support frame 9. The loading basket support frame 9 that supports the loading basket assembly 8 is provided in the feeding rack grooves 10. A robotic arm base plate 3 is fixedly connected inside the feeding trolley 4. A vision robotic arm 1 is fixedly connected to the upper surface of one end of the robotic arm base plate 3.

[0030] In addition, such as Figure 1 and Figure 2 As shown, the vision robotic arm 1 is an automated device combining vision system and robotic arm technology. Its components include a robotic arm with actuators, typically composed of multiple joints and links, enabling multi-degree-of-freedom movement and flexible grasping, handling, and manipulation of objects in three-dimensional space. It also includes a vision system 16, consisting of a camera, lens, light source, image acquisition card, and vision processing software. The camera acquires image information of the work scene, the lens adjusts the imaging effect, the light source provides suitable lighting conditions for shooting, the image acquisition card converts the analog signals acquired by the camera into digital signals and transmits them to the computer, and the vision processing software analyzes, processes, and recognizes the images to obtain information such as the object's position, shape, and posture. The vision system 16 first photographs and analyzes the target object or work scene, identifying the object's features and position information, and then transmits this information to the robotic arm's control system. Based on the received visual information, the control system calculates the path and posture that the robotic arm needs to move, and controls the joint movement of the robotic arm through actuators such as drive motors, enabling the robotic arm to accurately reach the target position and complete tasks such as grasping, placing, and assembling. The vision robotic arm 1 is equipped with a gripper 18 for gripping the loading basket assembly 8, and a vision system 16 is also provided on the vision robotic arm 1.

[0031] It is worth noting that, such as Figure 4 As shown, one end of the wedge-shaped insert 12 inserted into the clamp 17 is fixedly connected to a triangular plug 121. The triangular plug 121 serves as a guide to ensure that the wedge-shaped insert 12 is inserted into the clamp 17 more smoothly and efficiently.

[0032] Furthermore, such as Figure 3 and Figure 6 As shown, the loading basket assembly 8 includes a loading basket 14, which is used to hold the materials to be processed. Depending on the different application scenarios of the vacuum furnace 6, the materials may be various metal parts, powder materials, electronic components, etc. It can hold a certain amount of material to ensure that the material does not scatter or move around during the operation of the vacuum furnace, thus ensuring the stability of the material during processing. The loading basket 14 is equipped with a baffle 15 inside, which can limit the movement range of the material in the basket. Especially during transportation, lifting, or vacuum furnace operation, when there is vibration or tilting, it can effectively prevent the material from falling out of the basket, ensuring that the material is processed intact.

[0033] In this embodiment, when using the vacuum furnace feeding mechanism, first push the handle 19 to move the feeding cart 4 towards one end of the vacuum furnace 6. By observing the high-intensity indicator light 63 on the end of the guide block 61, it can be seen that the feeding cart 4 can easily be inserted into the middle of a pair of guide blocks 61 even in environments with low visibility. At the same time, the feeding cart 4 will also move the pair of feeding cart guide rails 2 on it. The feeding cart guide rails 2 will then drive the wedge-shaped inserts 12 at the corresponding ends to insert into the clamps 17 at the end of the vacuum furnace feeding rail 11, thereby allowing the feeding cart 4 to move as shown in the picture. Figure 1 The state shown is placed at the end of vacuum furnace 6.

[0034] When it is necessary to push the loading basket assembly 8 on the loading basket support frame 9 in the feeding rack groove 10 into the vacuum furnace 6, simply activate the vision robotic arm 1 on the robotic arm base plate 3. After activation, the vision robotic arm 1 fixes the feeding rack groove 10 with the gripper 18, and with the cooperation of the vision system 16, the loading basket assembly 8 can move in and out of the vacuum furnace 6. During entry and exit, the loading basket support frame 9 engages with the feeding rack groove 10 in the feeding rack 5, thereby causing the loading basket support frame 9 to drive the feeding rack 5 to slide along the slide groove 7 in the vacuum furnace loading rail 11 into and out of the vacuum furnace 6, which is quick and convenient.

[0035] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
