Description

Technical Field

[0001] This utility model relates to the field of automatic processing equipment technology, and in particular to a material fixing module for stable lifting and lowering. Background Technology

[0002] Material lifting devices are key functional modules in modern industrial production lines and automated equipment, widely used in precision assembly, inspection and positioning, loading and unloading, and inter-layer conveying. Their core function is to achieve stable vertical displacement of materials or tooling platforms, providing an accurate and reliable positioning basis for subsequent operations. However, in existing technical solutions, such lifting modules still face a series of inherent challenges in terms of long-term operational stability, repeatability, and ease of maintenance.

[0003] Currently, most common lifting mechanisms use linear guides, guide columns, guide sleeves, or slides as guiding structures. After a period of operation, these structures inevitably develop movement gaps due to factors such as mechanical wear, accumulated processing errors, or installation stress. These gaps cause slight wobbling or swaying of the lifting platform during movement, which not only directly affects the material positioning accuracy but may also cause vibrations, adversely affecting precision operations or sensitive materials. Furthermore, conventional guiding structures lack real-time sensing capabilities regarding their own wear status and fit tightness, making early warning or adaptive compensation impossible. This often necessitates manual inspection and adjustment after shutdown, impacting the efficiency of continuous equipment operation.

[0004] In the connection and calibration of the material platform and the lifting drive mechanism, traditional methods typically rely on screw locking with locating pins. During installation, repeated manual adjustments are required, resulting in low efficiency and demanding high operator skill. More importantly, this rigid connection method struggles to eliminate minor misalignments caused by machining errors or thermal deformation, potentially leading to internal installation stress. Over time, this stress accelerates localized wear of the guide components, compromising the original motion accuracy.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0018] This utility model provides a stable lifting and lowering material fixing module. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. In the description of this utility model, it should be understood that the terms "up, down, left, right," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] Please see Figures 1 to 3This invention provides a stable lifting and lowering material fixing module, including a fixed base 1, a lifting drive assembly 2, a connecting block 3, a guide structure, a calibration assembly, and a material platform 4. Specifically, the fixed base 1 serves as the overall supporting frame, with the lifting drive assembly 2 (such as a cylinder or electric push rod) installed on its outer wall. The power output end of the drive assembly is rigidly connected to the connecting block 3. A clearance notch 5 is provided on the edge of the fixed base 1 to accommodate the reciprocating motion of the connecting block 3 in the vertical direction. Wedge-shaped blocks 6 are embedded in the inner walls of both sides of the clearance notch 5. The wedge-shaped blocks 6 have inclined guide contact surfaces, ensuring that the connecting block 3 is always constrained by the inclined surfaces of the wedge-shaped blocks 6 during lifting and lowering, thus providing a centering guide effect. A pressure sensor is integrated into the guide contact surface of each wedge-shaped block 6 to sense the pressure when the connecting block 3 contacts it in real time, thereby determining whether there is an off-center load, jamming, or imbalance. The material platform 4 is fixed to the top of the connecting block 3, and two calibration pin holes are opened on its bottom surface. Two calibration pins 7 are symmetrically arranged on the top of the fixed seat 1 and on both sides of the clearance notch 5. The top of the pin is machined into a frustum-shaped calibration end (i.e., a frustum structure that is smaller at the top and larger at the bottom). When the material platform 4 descends into place, the frustum-shaped calibration end automatically enters the calibration pin hole, and high-precision self-positioning is achieved through the conical surface cooperation, eliminating accumulated errors.

[0020] The clearance notch 5 is designed as a through opening, with wedge blocks 6 installed on its two opposite side walls (left and right side walls), and each wedge block 6 has an integrated independent pressure sensor on its guide contact surface. The left and right sides of the connecting block 3 can contact the inclined surfaces of the wedge blocks 6. Thus, during the lifting process, the connecting block 3 is clamped and guided by the wedge blocks 6 on both sides, forming a bidirectional constraint. This not only improves lateral stability but also allows for the determination of whether deflection has occurred by comparing the data from the pressure sensors on both sides, providing more comprehensive feedback information to the controller.

[0021] It also includes a controller, which is electrically connected to each pressure sensor via signal lines to receive real-time pressure data. Simultaneously, the controller is also electrically connected to the lifting drive assembly 2 (such as a cylinder solenoid valve, servo motor driver, etc.), forming a closed-loop control system. When a pressure sensor detects an abnormal increase in pressure on one side or the pressure difference between the two sides exceeds a preset threshold, the controller can immediately adjust the operating speed of the lifting drive assembly 2, stop its operation, or make reverse fine adjustments to restore balance, preventing structural damage or positioning failure due to uneven force, thus achieving intelligent dynamic control.

[0022] To further improve the smoothness and torsional resistance of the lifting process, a lifting guide assembly is added to the side wall of the fixed base 1. This assembly includes a vertical lifting rail 8 fixed to the fixed base 1 and a guide block 9 fixed to the bottom of the material platform 4 or the connecting block 3. The guide block 9 and the lifting rail 8 form a sliding or rolling engagement. The guide assembly structure undertakes the main vertical guiding task and shares the guiding load of the wedge block 6, enabling the system to maintain high rigidity and low friction operation under high-speed or heavy-load conditions. Specifically, to optimize the force distribution and enhance the structural symmetry, the lifting rail 8 is symmetrically arranged on the left and right sides of the lifting drive assembly 2. For example, if the lifting drive assembly 2 is a single cylinder installed in the middle, a set of lifting rails 8 and guide blocks 9 are provided on its left and right sides respectively; if the drive assembly is a double cylinder, the rails can be arranged outside the two cylinders. This layout ensures that the material platform 4 is subjected to uniform force during the lifting process, effectively suppresses torsion around the Z-axis (vertical axis) or tilting around the X / Y axes, and improves the overall motion accuracy.

[0023] Preferably, the lifting drive assembly 2 employs at least two lifting cylinders mounted side-by-side on the outer wall of the fixed base 1. The controller is connected to the solenoid valve of each cylinder, and can independently or collaboratively control their intake and exhaust timing. During startup or load changes, the controller adjusts the air supply pressure or throttle valve opening of each cylinder based on feedback from the pressure sensor, achieving synchronous compensation of multiple cylinders and avoiding lifting asynchrony problems caused by manufacturing tolerances or wear.

[0024] At the material handling station of material platform 4, a rotary motor 10 facing upwards is fixedly installed. Preferably, the rotary motor 10 is a stepper motor or a servo motor, with its output axis extending upwards and connected to a vacuum suction cup. The vacuum suction cup can be connected to a vacuum source via a rotary joint. When material is placed above the suction cup, the vacuum system starts to adsorb the material. When the material angle needs to be adjusted, the rotary motor 10 drives the suction cup and the adsorbed material to rotate synchronously, realizing orientation correction or process angle switching. This structure is particularly suitable for automated processing scenarios of sheet-like, disc-like, or symmetrical materials that require precise orientation.

[0025] In summary, the stable lifting material fixing module of this utility model achieves multifaceted synergistic optimization through the rational integration of the structural design of the fixing seat 1, lifting drive component 2, connecting block 3, guide structure, calibration component, and material platform 4. By utilizing the fitting and embedding of the notch 5 in the fixing seat 1 and the connecting block 3, combined with the guide structure formed by the wedge block 6, it provides stable and reliable guidance for the lifting motion, effectively avoiding problems such as deviation and swaying during the lifting process. Simultaneously, the pressure sensor on the guide contact surface of the wedge block 6 can detect the contact pressure between the connecting block 3 and the wedge block 6 in real time, facilitating timely detection of abnormal force conditions during the lifting process and ensuring the safety and stability of the module's operation. Furthermore, the symmetrically arranged calibration pins 7 and the calibration pin holes at the bottom of the material platform 4, combined with the guiding calibration function of the frustum-shaped calibration end, enable rapid and precise alignment calibration after the material platform 4 is raised and lowered into position. This significantly improves the positioning accuracy of the fixed material, allowing for precise positioning without manual intervention, which helps simplify the operation process and improve production efficiency. The overall structure is compact and reasonable, with smooth cooperation among the components. This not only improves the operational stability and service life of the module but also better adapts to the high-precision and high-stability requirements of industrial production, providing a reliable guarantee for the smooth operation of subsequent processes. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0026] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
