Description

Technical Field

[0001] This utility model relates to the field of film cutting equipment technology, and in particular to a sheet material protective film slicing equipment. Background Technology

[0002] During the production, transportation, and storage of sheet materials, a protective film is usually applied to their surface to prevent scratches and contamination. This protective film needs to be peeled off before the sheet materials are used. To facilitate peeling, the protective film is usually cut into specific shapes or segments. Currently, common protective film cutting equipment on the market mainly relies on two technical solutions. The first is a handheld cutting tool, which relies entirely on the operator's experience and feel to control the cutting depth and path. This method is not only inefficient and labor-intensive, but also has extremely unstable cutting quality. It is very easy to damage the expensive sheet material substrate due to excessive force, or to fail to peel off the protective film due to insufficient cutting depth, causing production interruptions and quality problems. The second type is a more automated fixed or simple sliding rail cutting machine. This type of equipment usually fixes the cutting blade to a robotic arm or slide, and moves in a straight line or simple curve under program control. Compared to manual cutting, its efficiency and consistency are improved. However, they still have several inherent technical defects: they cannot adapt to thickness variations; the thickness of the protective film may vary between different batches or different regions; and equipment with a fixed cutting depth is prone to damaging the sheet material itself or failing to cut deep enough, resulting in the protective film failing to peel off smoothly. Uneven tool wear: During the cutting process, specific parts of the tool are subjected to continuous stress, which can easily lead to one-sided wear, shorten tool life, and affect cutting quality. Insufficient flexibility: For scenarios requiring curved cutting or complex pattern cutting, traditional equipment struggles to flexibly adjust the tool angle. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a sheet metal protective film slicing device that features high cutting precision, adaptability to film thickness, and long blade life.

[0004] This utility model provides a sheet metal protective film slicing device, comprising: a worktable with first slide rails arranged along a first direction on both sides of its upper surface; at least one sliding beam with its two ends slidably connected to the first slide rails, and a second slide rail arranged along a second direction on the sliding beam; at least one set of cutting components, including a mounting base, a cutting tool, and a driving mechanism; the mounting base is slidably connected to the second slide rail; the driving mechanism is disposed on the mounting base and is configured to drive the cutting tool to perform rotational and lifting movements; a thickness detection component, fixed to the outside of the mounting base, with the detection probe of the thickness detection component facing the worktable; and a driving component for driving the sliding beam to move along the first slide rail and the cutting component to slide along the second slide rail.

[0005] As an improvement to the above solution, the thickness detection component is a non-contact laser detection component.

[0008] As an improvement to the above solution, the rotary drive unit includes: an upper support fixed to the upper end of the mounting cavity; a first rotating block rotatably connected to the upper support; a lower support fixed to a mounting platform below the mounting cavity; a second rotating seat rotatably connected to the lower support; a connecting sleeve whose two ends are respectively fixedly connected to the first rotating seat and the second rotating seat; and a rotary drive component disposed in the mounting cavity for driving the second rotating seat to rotate.

[0014] The beneficial effects of implementing this utility model are as follows:

[0015] This utility model discloses a protective film slicing device for sheet metal. Through a thickness detection component, it provides real-time feedback of film thickness data. The control system dynamically adjusts the stroke of the lifting drive component, ensuring that the cutting depth always precisely penetrates the protective film without damaging the sheet metal substrate. This fundamentally overcomes the quality defects of existing technologies, such as excessively deep or shallow cuts caused by uneven film thickness or inaccurate preset cutting depths. The drive mechanism allows the blade to rotate during the cutting process, avoiding the problem of continuous wear on one side of the blade when cutting at a fixed angle. This results in even wear distribution, reducing the frequency of blade replacement and maintenance costs, while ensuring a smooth and consistent cut over long-term cutting operations. The cutting component can move precisely in the X and Y axes under the drive component. Combined with the rotation of the blade itself, the device can easily complete high-precision cuts of straight lines, curves, and complex patterns, meeting the high requirements of flexibility and customization in modern processing.

Detailed Implementation

[0021] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0022] See Figures 1-2 , Figure 1 This is a schematic diagram of the structure of a sheet metal protective film cutting device according to an embodiment of this application; Figure 2This is a partial top view of a cutting component of a sheet metal protective film slicing device according to an embodiment of this application. As shown in the figure, the device includes: a workbench 100, with first slide rails 110 arranged along a first direction on both sides of its upper surface; at least one sliding beam 200, with its two ends slidably connected to the first slide rails 110 respectively, and a second slide rail 210 arranged along a second direction on the sliding beam 200; at least one set of cutting components 300, including a mounting base 310, a cutting tool 320, and a driving mechanism; the mounting base 310 is slidably connected to the second slide rail 210; the driving mechanism is disposed on the mounting base 310, and the driving mechanism is configured to drive the cutting tool 320 to perform rotational and lifting movements; a thickness detection element 400, fixed to the outside of the mounting base 310, with the detection probe of the thickness detection element 400 facing the workbench 100; and a driving component 500, used to drive the sliding beam 200 to move along the first slide rail 110 and the cutting component 300 to slide along the second slide rail 210 respectively. The thickness detection component 400 provides real-time feedback on film thickness data, and the control system can dynamically adjust the stroke of the lifting drive component 340 to ensure that the cutting depth always accurately penetrates the protective film without damaging the substrate. This fundamentally overcomes the quality defects of existing technologies, such as cutting too deep or too shallow due to uneven film thickness or inaccurate preset cutting depth. The drive mechanism allows the tool to rotate during the cutting process, avoiding the problem of continuous wear on one side of the cutting edge when cutting at a fixed angle. This ensures uniform wear distribution, reduces the frequency of tool replacement and maintenance costs, and guarantees a smooth and consistent cut under long-term cutting operations. The cutting component 300 can move precisely in the X and Y axes under the drive component 500. Combined with the rotation of the tool itself, the equipment can easily complete high-precision cutting of straight lines, curves, and complex patterns, meeting the high requirements of flexibility and customization in modern processing.

[0023] Specifically, the thickness detection component 400 is a non-contact laser detection component. It boasts extremely high measurement accuracy and response speed, meeting the real-time acquisition requirements for film thickness data during high-speed cutting. Non-contact measurement will not cause any scratches or indentations to the soft protective film surface, ensuring the product's integrity. It also has strong anti-interference capabilities: compared to contact sensors, laser detection is less susceptible to interference from environmental factors such as vibration and oil contamination, resulting in better operational stability.

[0024] Preferably, the non-contact laser detection device is a spectral confocal displacement sensor. In use, the sensor's light spot penetrates the upper and lower surfaces of the thin film and reflects back to the probe, then is transmitted to the controller via optical fiber. An algorithm calculates the reflected light from the two surfaces, determines the relative height of the upper and lower surfaces of the thin film, and thus calculates the film thickness. The spectral confocal displacement sensor is one of the most accurate non-contact measurement technologies currently available, particularly suitable for precise thickness measurement of transparent, mirror-like, or multilayer thin films. It effectively solves the error problems that may occur when ordinary laser sensors measure transparent protective films. It is insensitive to the material, color, and surface gloss of the measured object, possessing strong versatility, enabling this device to handle various types of sheets and protective films.

[0025] See Figure 2 Furthermore, in this embodiment, the mounting base 310 has a mounting block 311 on its side, and the mounting block 311 has a mounting hole. The thickness detection component 400 is detachably mounted in the mounting hole. This detachable connection facilitates the position calibration, cleaning, replacement, or upgrading of the thickness detection component 400, greatly reducing the maintenance difficulty and time cost of the equipment. The dedicated mounting block 311 and mounting hole structure ensure the positioning accuracy of the thickness detection component 400 relative to the mounting base 310 and the cutting tool 320, avoiding loosening or deviation that may occur when using general-purpose fixtures, thereby ensuring the reliability of the detection data.

[0026] See Figure 2 and Figure 3 , Figure 3 This is a second partial top view of the cutting component 300 of a sheet metal protective film slicing device in this application embodiment;

[0027] Furthermore, in this embodiment, the driving mechanism includes: a rotary driving unit 330, disposed within the mounting cavity of the mounting base 310; and a lifting driving component 340, connected to the rotary driving unit 330, with the power output end of the lifting driving component 340 extending below the mounting base 310 and connected to the cutting tool 320. By implementing the rotary motion and the lifting motion separately by independent units, the control of the two motions becomes more precise and they do not interfere with each other. Integrating these two units within the mounting base 310 optimizes the spatial layout, making the overall structure of the cutting assembly 300 more compact, which is beneficial for the miniaturization of the equipment and its application in confined spaces.

[0028] Preferably, the mounting base 310 is provided with a hinged upper cover, which facilitates opening the mounting cavity through the upper cover.

[0029] Furthermore, in this embodiment, the rotary drive unit 330 includes: an upper support 331 fixed to the upper end of the mounting cavity; a first rotating block 332 rotatably connected to the upper support 331; a lower support 333 fixed to the mounting platform 312 below the mounting cavity; a second rotating seat 334 rotatably connected to the lower support 333; a connecting sleeve 335, with its two ends fixedly connected to the first rotating seat and the second rotating seat 334 respectively; and a rotary drive component disposed within the mounting cavity for driving the second rotating seat 334 to rotate. The double-support rotary structure formed by the upper support 331, the lower support 333, and the connecting sleeve 335 provides extremely high rotational rigidity and stability, effectively reducing the vibration and sway of the tool under cutting force, and ensuring the accuracy of the cutting path.

[0030] Specifically, the rotary drive unit 330 includes a drive motor 336, which is connected to the second rotating seat 334 via a synchronous belt 337. The synchronous belt 337 transmission has a buffering and vibration-absorbing effect, making the tool rotation smoother and reducing working noise. By selecting pulleys with different tooth counts, the output speed can be easily adjusted to adapt to different cutting needs. At the same time, the synchronous belt 337 transmission structure is simple, easy to replace, and has low cost.

[0031] Furthermore, in this embodiment, the lifting drive component 340 is disposed in the internal cavity of the connecting sleeve 335. The lifting drive component 340 is fixedly connected to the first rotating seat, and the power output end of the lifting drive component 340 passes downward through the mounting platform 312 and connects to the cutting tool 320. By embedding the lifting drive component 340 inside the connecting sleeve 335 of the rotating mechanism, a "mechanism nesting" is achieved, which greatly saves installation space and minimizes the axial dimension of the entire drive mechanism.

[0032] Preferably, the connecting sleeve 335 is a semi-open sleeve, which facilitates the air passage, oil passage or wire of the lifting drive component 340 to enter the sleeve and be arranged so that it rotates with the mechanism, avoiding safety hazards such as entanglement and wear of exposed pipelines during complex movements.

[0033] Furthermore, in this embodiment, the driving assembly 500 includes: a first driving unit connected to the sliding beam 200 for driving it to move along the first slide rail 110; and a second driving unit connected to the mounting base 310 for driving it to slide along the second slide rail 210. The two driving units control the X-axis and Y-axis movements respectively, enabling complex CNC interpolation movements and completing the cutting of arbitrary planar trajectories.

[0034] See Figure 4 , Figure 4This is a top view of a sheet metal protective film cutting device according to an embodiment of this application;

[0035] Furthermore, in this embodiment, the workbench 100 is provided with two parallel sliding beams 200, and each sliding beam 200 is slidably equipped with a set of cutting components 300. The dual-station design allows for simultaneous cutting of two plates or different areas of a single plate, or one plate can be used for roughing and the other for finishing, thereby significantly improving the equipment's production efficiency. The two cutting components 300 can be configured with different blades or employ different cutting strategies, increasing the equipment's process adaptability and functionality.
