Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, and in particular to a feeding mechanism for a semi-automatic cutting machine. Background Technology

[0002] In the field of automated production for sheet metal processing equipment, especially in the material handling process of semi-automatic panel cutters, how to efficiently and stably achieve precise gripping and handling of sheet metal has always been a key direction for technological optimization. Currently, the commonly used configuration in the industry is to use a gripping robot consisting of a single vacuum suction cup to complete the sheet metal picking action. The specific implementation of this traditional technical solution is usually as follows: the vacuum suction cup is directly placed below the end effector of the robot, and the suction operation is carried out by relying solely on the suction cup itself to press vertically down from the top surface of the sheet metal and form a sealed negative pressure with the surface of the sheet metal.

[0003] However, the aforementioned conventional technical solutions have significant drawbacks in actual operation. Because the working position of the suction cup is strictly limited to the upper area of ​​the material, its effective contact area with the material is limited by the suction cup's own structural dimensions and layout, making it difficult to fully cover the entire force-bearing surface of the material. Especially when handling materials with poor surface flatness, minor deformation, or attached dust and impurities, a single suction cup can only maintain the material's state through limited adsorption force in a localized area, making it highly susceptible to adsorption failure due to air pressure fluctuations, uneven material weight distribution, or external interference. This insufficient adsorption reliability not only leads to abnormal conditions such as material detachment and positioning misalignment, directly affecting subsequent processing accuracy, but also forces frequent equipment shutdowns to readjust the material's position, severely restricting production efficiency. Furthermore, for materials with large areas or heavy weights, the adsorption torque provided by a single suction cup often fails to meet the mechanical balance conditions required for stable handling, further exacerbating operational risks. Therefore, the existing material handling method based on a single suction cup and applying force only from above is no longer suitable for high-precision, high-efficiency production demands, and structural improvements are urgently needed to enhance adsorption stability and process adaptability.

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a semi-automatic material feeding mechanism for cutting a material cutting machine, so as to solve one or more problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a semi-automatic panel cutting machine loading mechanism, comprising a gripping robot and a lifting platform disposed around the main frame. The gripping robot includes an X-axis module, a Z-axis module, a mounting platform, and a vacuum suction cup. The mounting platform is mounted on the X-axis module via the Z-axis module. The X-axis module is mounted on the main frame. The vacuum suction cup is fixed to the mounting platform and is used to transport the sheet metal on the lifting platform to the working platform of the main frame. The lifting platform includes a carrying platform, a push cylinder, a base, and a scissor-type telescopic frame. A scissor-type telescopic frame is disposed between the carrying platform and the base. The scissor-type telescopic frame is symmetrically arranged on opposite sides of the carrying platform. The push cylinder is disposed on the base, and its cylinder rod is connected to the carrying platform to drive the carrying platform to lift.

[0006] In one embodiment of the present invention, the X-axis module includes an X-axis servo motor and an X-axis slide, the X-axis servo motor drives the X-axis slide laterally along the X-axis direction on the main frame, and the Z-axis module is disposed on the X-axis slide.

[0007] In one embodiment of the present invention, the Z-axis module includes a Z-axis servo motor and a Z-axis lifting frame. The Z-axis servo motor drives the Z-axis lifting frame to move up and down along the Z-axis direction, and the mounting platform is disposed on the Z-axis lifting frame.

[0008] In one embodiment of the present invention, a plurality of suction cup seats arranged side by side are detachably installed on the mounting platform, and each suction cup seat is equipped with the vacuum suction cup.

[0009] In one embodiment of this utility model, the X-axis servo motor, the Z-axis servo motor, and the push cylinder form a signal connection to achieve coordinated action.

[0010] In one embodiment of the present invention, a geared motor is also included. The Z-axis servo motor is connected to the geared motor and drives the Z-axis lifting frame to perform lifting and lowering actions via a rack and pinion.

[0011] In one embodiment of the present invention, the scissor-type telescopic frame includes an inner support rod and an outer support rod that are X-shaped and cross-connected, and the upper and lower ends of the inner support rod and the outer support rod are respectively hinged to the loading platform and the base.

[0012] In one embodiment of the present invention, a connecting rod is further provided transversely through the inner support rod and the outer support rod, and a tie arm is hinged between the connecting rods to enhance the structural stability of the scissor telescopic frame.

[0013] As described above, the semi-automatic panel cutting machine feeding mechanism of this utility model has the following beneficial effects: Through the coordinated action of the gripping robot and the lifting platform, force is applied simultaneously from both the top and bottom sides of the board. When the vacuum suction cup adsorbs the board from top to bottom, the lifting platform can provide stable support and auxiliary lifting force from bottom to top, forming a two-way clamping effect. This effectively overcomes the problems of uneven board surface, warping, or insufficient suction force, significantly improving the stability and reliability of the handling process, and preventing the board from shifting or falling off during transfer, thereby ensuring feeding accuracy and overall operational safety.

[0019] This utility model provides a feeding mechanism for a semi-automatic cutting machine. 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.

[0020] Please see Figure 1 and Figure 2 This utility model provides a semi-automatic panel saw loading mechanism, including a gripping robot and a lifting platform disposed around the main frame. The gripping robot includes an X-axis module 1, a Z-axis module, a mounting platform 3, and a vacuum suction cup 4. The mounting platform 3 is mounted on the X-axis module 1 via the Z-axis module 2. The X-axis module 1 is mounted on the main frame. The vacuum suction cup 4 is fixed to the mounting platform 3 and is used to transport the sheet metal on the lifting platform to the working platform of the main frame. Specifically, several suction cup seats 9 are detachably mounted on the mounting platform 3, and each suction cup seat 9 is equipped with the vacuum suction cup 4. It is understood that the suction cup seats 9 can be easily installed and removed to adapt to the needs of sheet metal of different sizes and shapes. By adjusting the position and number of suction cup seats 9, the layout of the vacuum suction cup 4 can be flexibly changed, thereby optimizing the adsorption effect and ensuring that a uniform clamping force is applied to the sheet metal during transportation. In addition, this modular design also facilitates the maintenance and replacement of damaged suction cup components, reducing equipment downtime and maintenance costs.

[0021] The lifting platform includes a loading platform 5, a push cylinder 6, a base 7, and a scissor-type telescopic frame 8. The scissor-type telescopic frame 8 is positioned between the loading platform 5 and the base 7, symmetrically arranged on opposite sides of the loading platform 5. The push cylinder 6 is mounted on the base 7, and its cylinder rod is connected to the loading platform 5 to drive its lifting and lowering. In actual operation, the coordinated work of the X-axis module 1 and the Z-axis module 2 provides a reliable guarantee for the precise positioning of the sheet metal. The X-axis servo motor 11 drives the X-axis slide 12 to move laterally along the main frame, while the Z-axis servo motor 21 controls the Z-axis lifting frame 22 for vertical adjustment. This combination allows the gripping robot to move freely in three-dimensional space, quickly reaching the designated position and completing the material handling task. It is worth mentioning that the introduction of the reduction motor 23 effectively improves the smoothness of the Z-axis module 2's operation, especially when handling larger sheet metals. The rack and pinion transmission significantly reduces impact and vibration, further improving operational safety and efficiency.

[0022] The X-axis module 1 includes an X-axis servo motor 11 and an X-axis slide 12. The X-axis servo motor 11 drives the X-axis slide 12 to slide laterally along the X-axis direction on the main frame. The Z-axis module 2 is mounted on the X-axis slide 12. The Z-axis module 2 includes a Z-axis servo motor 21 and a Z-axis lifting frame 22. The Z-axis servo motor 21 drives the Z-axis lifting frame 22 to move up and down along the Z-axis direction. The mounting platform 3 is mounted on the Z-axis lifting frame 22. A reduction motor 23 is also included. The Z-axis servo motor 21 is connected to the reduction motor 23, and drives the Z-axis lifting frame 22 to perform lifting and lowering actions via a rack and pinion mechanism. The X-axis servo motor 11, the Z-axis servo motor, and the push cylinder 6 form a signal connection to achieve coordinated operation.

[0023] Furthermore, the design of the lifting platform also reflects a high degree of practicality and stability. The scissor-type telescopic frame 8 includes an inner support rod 81 and an outer support rod 82 connected in an X-shape, forming a support structure with excellent mechanical properties. When the cylinder 6 drives the platform 5 to lift, the scissor-type telescopic frame 8 can maintain a smooth unfolding and retraction action, avoiding shaking or jamming caused by uneven force. The upper and lower ends of the inner support rod 81 and the outer support rod 82 are respectively hinged to the platform 5 and the base 7. To enhance the stability of the scissor-type telescopic frame 8 during the telescopic process, a connecting rod 83 is also included, which is transversely inserted through the inner support rod 81 and the outer support rod 82. A tie arm 84 is hinged between the connecting rods 83 to enhance the structural stability of the scissor-type telescopic frame 8.

[0024] In practical applications, the scissor lift 8 effectively distributes the weight borne by the loading platform 5, ensuring uniform force distribution during lifting. The cooperation between the connecting rod 83 and the pull arm 84 not only enhances the overall rigidity of the scissor lift 8 but also maintains structural reliability after prolonged use, reducing the risk of failure due to fatigue or deformation. Furthermore, the stroke and speed of the driving cylinder 6 can be precisely adjusted through the control system to adapt to the needs of plates of different thicknesses and weights, while ensuring smooth and consistent operation. Through these detailed optimizations, the lifting platform not only achieves efficient material conveying but also significantly enhances the equipment's durability and operational safety, providing strong support for the entire loading process.

[0025] In summary, the semi-automatic panel cutting machine loading mechanism of this invention employs a collaborative working mechanism between a gripping robot and a lifting platform. This allows both to apply force simultaneously from both the top and bottom of the panel, forming a stable, two-way interactive system. Specifically, the vacuum suction cup 4 in the gripping robot applies negative pressure to the panel from above, while the lifting platform 5 supports the panel from below. Together, they form a mutually supportive mechanical structure. This three-dimensional force application effectively overcomes the instability caused by traditional unilateral adsorption, which is susceptible to panel deformation, surface conditions, and environmental interference. The combined force from both above and below significantly improves the positioning accuracy and stability of the panel during handling. Especially when handling large or irregularly shaped panels, this structure dynamically balances the panel's own weight distribution with the matching relationship of external forces. This avoids the slippage risk that may arise from relying solely on vacuum adsorption and eliminates the technical bottleneck of achieving precise positioning with only bottom support, thus creating a more reliable panel gripping and transfer system. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses 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.
