Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a material loading platform for automation equipment. Background Technology

[0002] In modern industrial production, especially in automated assembly, logistics and precision manufacturing, material loading platforms for automated equipment serve as crucial transition and positioning devices. They are widely used to transfer, lift, and precisely position materials or workpieces between workstations. Their core function is to move materials quickly, smoothly, and accurately from one height or position to another preset height or position to meet the precision requirements of subsequent processing, inspection, or assembly.

[0003] Traditional material loading platforms typically employ lifting mechanisms, such as motor-driven lead screws or cylinders, to move the loading platform vertically. However, these devices generally suffer from a technical bottleneck in practical use: insufficient repeatability. After multiple lifting cycles, due to transmission gaps between the lead screw and nut, wear or minor deformation of the lifting guide rails, and accumulated errors in motor control, the actual horizontal position (in the X and Y axes) of the loading platform may shift slightly when it returns to the same theoretical height. Such millimeter-level or even smaller deviations are unacceptable for automated production lines requiring high-precision docking (e.g., loading workpieces into high-precision fixtures, or accurately transferring them to the end effector of a robotic arm), easily leading to material jamming, assembly failure, or even equipment damage.

[0004] To address the positioning error problem, some existing solutions may use additional visual inspection systems for position compensation after the equipment has come to a complete stop, or rely on manual fine-tuning by operators. However, the former significantly increases the complexity and cost of the system, while the latter reduces automation efficiency, contradicting the original intention of automation design. Clearly, existing technologies require improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a material loading platform for automated equipment to solve one or more problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a material loading platform for automated equipment, comprising a base, a lifting frame assembly, a calibration assembly, and a lifting cylinder disposed on the base; the lifting frame assembly comprises a main load frame and a load plate fixed to the top of the main load frame, the main load frame being slidably disposed on the base via a lifting rail; The calibration assembly includes calibration pins and calibration pin holes adapted to the calibration pins. At least two calibration pins are provided on the top of the base. The top of the calibration pins is provided with a frustum-shaped calibration end. The calibration pin holes are opened at the bottom of the loading plate. The output rod of the lifting cylinder is fixedly connected to the loading plate.

[0007] In one embodiment of the present invention, a rotary motor and a vacuum suction cup are also included. The rotary motor is provided on the main frame of the load, and a vacuum suction cup is installed at the output end of the rotary motor.

[0008] In one embodiment of this utility model, the loading plate is provided with a mounting through hole, and the rotary motor passes through the mounting through hole.

[0009] In one embodiment of the present invention, the lifting rails are symmetrically arranged about the center line of the base, and the lifting cylinder is arranged between the two lifting rails.

[0010] In one embodiment of the present invention, the base includes a vertically arranged mounting wall plate, and the lifting cylinder is disposed on the mounting wall plate.

[0011] In one embodiment of this utility model, at least two lifting cylinders are arranged side by side on the mounting wall panel.

[0012] In one embodiment of the present invention, a synchronization block is also included. The lifting cylinder is connected to the load plate through the synchronization block to realize the synchronous movement of multiple lifting cylinders.

[0013] In one embodiment of the present invention, a trapezoidal reinforcing rib is provided on the side of the mounting wall panel opposite to the lifting cylinder.

[0014] As described above, the material loading platform for automated equipment of this invention has the following beneficial effects: by creatively combining the calibration component with the lifting drive structure, automatic and precise positioning and self-correction of the material loading platform during the lifting process are achieved. Its core beneficial effect lies in the fact that when the loading plate descends, the ingenious cooperation between the frustum-shaped calibration end of the calibration pin on the base and the pin hole on the loading plate automatically guides and forcibly corrects the final stopping position of the loading plate, effectively eliminating horizontal orientation errors caused by factors such as lead screw drive backlash, track wear, or minor deformation. This purely mechanical hard calibration method does not rely on expensive sensors or complex electronic control compensation systems; it actively completes high-precision repetitive positioning at the end of each cycle, greatly improving the positioning accuracy and long-term operational reliability of the equipment. Simultaneously, this structure decouples and synergizes the lifting drive and precise positioning functions, enabling the equipment to achieve excellent positioning stability while maintaining the simplicity and efficiency of the overall structure, significantly reducing manufacturing and maintenance costs.

[0018] This utility model provides a material loading platform for automated equipment. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following detailed description is provided 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," and "right," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description; they should not be construed as limitations on this utility model. Furthermore, 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 utility model provides a material loading platform for automated equipment, including a base 1, a lifting frame assembly, a calibration assembly, and a lifting cylinder 2 disposed on the base 1; the lifting frame assembly includes a main load frame 3 and a load plate 4 fixed to the top of the main load frame 3, the main load frame 3 being slidably disposed on the base 1 via a lifting rail 5; more importantly, the calibration assembly includes calibration pins 6 and calibration pin holes 7 adapted to the calibration pins 6, at least two calibration pins 6 are disposed on the top of the base 1, the top of the calibration pins 6 is provided with a frustum-shaped calibration end 8, the calibration pin holes 7 are opened at the bottom of the load plate 4, and the output rod of the lifting cylinder 2 is fixedly connected to the load plate 4.

[0020] Specifically, at least two calibration pins 6 are securely installed on the top surface of the base 1, with the top of each pin machined into a frustum-shaped calibration end 8, which is smaller at the top and larger at the bottom. Correspondingly, calibration pin holes 7, matching the position and size of the calibration pins 6, are machined on the bottom of the carrying plate 4. The lifting cylinder 2 is vertically mounted on the base 1, and the top of its output rod is directly fixedly connected to the bottom of the carrying plate 4. During operation, the lifting cylinder 2 acts as a push rod, driving the carrying plate 4 and the entire lifting frame assembly to rise or fall along the lifting track 5. When the carrying plate 4 descends close to the base 1, the frustum-shaped calibration end 8 will first enter the calibration pin hole 7, using its conical guiding effect to automatically correct the slight positional deviation of the carrying plate 4 in the horizontal plane (X, Y directions), ultimately allowing the pin to be fully inserted into the pin hole, achieving precise hard positioning.

[0021] In this embodiment, a rotary motor 9 and a vacuum suction cup are also included. The rotary motor 9 is mounted on the main frame 3, and the vacuum suction cup is installed at the output end of the rotary motor 9. It is understood that a negative pressure is provided to the vacuum suction cup through a vacuum pipeline system, enabling it to adsorb materials. The rotary motor 9 can drive the vacuum suction cup to rotate precisely within a range of 0° to 360°, thereby adjusting the orientation of the adsorbed materials and achieving posture adjustment of the materials during lifting and lowering. Specifically, the loading plate 4 has a mounting through hole 10, and the rotary motor 9 passes through the mounting through hole 10, meaning that the output end of the rotary motor 9 can protrude above the upper surface of the loading plate 4 to facilitate material adsorption. Simultaneously, the body of the rotary motor 9 is fixed to the main frame 3, not to the loading plate 4, ensuring the implementation of the rotation function while preventing the weight and vibration of the motor from directly affecting the positioning accuracy of the loading plate 4.

[0022] The lifting tracks 5 are symmetrically arranged about the centerline of the base 1, and the lifting cylinder 2 is disposed between the two lifting tracks 5. Optionally, the base 1 includes a vertically arranged mounting wall plate 11, and the lifting cylinder 2 is disposed on the mounting wall plate 11. The symmetrical arrangement of the lifting tracks 5 ensures that the lifting frame assembly is subjected to balanced forces during movement, preventing jamming or tilting. The lifting cylinder 2 is arranged between the two symmetrical lifting tracks 5, forming a stable and reliable support structure, which together guides and drives the lifting movement.

[0023] Preferably, at least two lifting cylinders 2 are arranged side-by-side on the mounting wall panel 11. The multi-screw structure is particularly suitable for carrying load-bearing flat plates 4 with large weights or wide areas. To further improve the stability of lifting, a synchronization block 12 is also included. The lifting cylinders 2 are connected to the load-bearing flat plate 4 through the synchronization block 12 to achieve synchronous movement of multiple lifting cylinders 2. It can be understood that the synchronization block 12 is a rigid connecting component that fixes the output rods of all lifting cylinders 2 together, and the synchronization block 12 itself is also fixed to the bottom of the load-bearing flat plate 4. Since the output rods are rigidly connected by the synchronization block 12, they must maintain completely consistent lifting movements, thereby forcing absolute synchronization of multiple lifting cylinders 2.

[0024] Please see Figure 2 To enhance the rigidity and stability of the base 1, especially the mounting wall panel 11, and to prevent it from bending or vibrating under load, a trapezoidal reinforcing rib plate 13 is welded or cast onto the side of the mounting wall panel 11 opposite to the lifting cylinder 2. Due to its wider bottom and narrower top geometry, the trapezoidal structure effectively distributes the load over a larger area of ​​the base 1, thereby reducing weight while providing optimal reinforcement and ensuring a robust and reliable support foundation for the entire lifting drive system.

[0025] In summary, the material loading platform for automated equipment of this utility model combines lifting motion with a frustum-shaped pin calibration structure. When the loading plate 4 is lowered to the working low position, the calibration pin 6 on the top of the base 1 and the pin hole on the bottom of the loading plate 4 automatically form a rigid positioning. The frustum-shaped calibration end 8 guides the plate to achieve smooth centering and posture correction, ensuring that the loading plane maintains accurate spatial position consistency even after multiple lifting cycles. This significantly improves the docking accuracy and repeatability of material transfer. At the same time, this integrated design simplifies the equipment debugging process, reduces the wear compensation requirements during long-term operation, and makes the overall structure more compact and easier to maintain, effectively meeting the continuous demand of automated production lines for efficient, stable, and high-precision material loading. 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.
