Description

Technical Field

[0001] This invention relates to the field of shoe last processing technology, and more specifically to a shoe last marking line processing device. Background Technology

[0002] In existing shoe last processing technology, laser marking (identifying shoe last size, serial number, manufacturer, and other identification information) is performed on random locations on the shoe last during processing. However, the performance of the shoe last in subsequent production is not ideal. Therefore, this invention, while marking the aforementioned basic information on the shoe last, also marks graduations and draws edge lines at designated locations on the curved surface of the shoe last. This allows for precise fitting of the upper into the shoe during production and facilitates inspection of the shaping quality of the shoe upper.

[0003] The shoe last itself is an integral structure composed of multiple curved surfaces. In existing technologies, when marking and identifying information on the shoe last, it is only necessary to find a flat surface and then mark it, and the accuracy requirement is also low. However, in this invention, it is often necessary to mark on the curved surface of the shoe last, and the accuracy requirement is high. In the early test, a robotic arm was used to hold the shoe last and control the three-axis movement and rotation of the shoe last so that different parts of the shoe last are located at the laser focal point of laser marking. This method requires the robotic arm to have high control precision, which is costly and inconvenient to use. Summary of the Invention

[0005] Preferably, the focusing lens group includes an X-axis galvanometer, a Y-axis galvanometer, and a Z-axis galvanometer. The X-axis galvanometer, the Y-axis galvanometer, and the Z-axis galvanometer are all connected to a driving mechanism. The driving mechanism is electrically connected to the visual positioning element. The driving mechanism controls the X-axis galvanometer and the Y-axis galvanometer to deflect around their axes and controls the Z-axis galvanometer to move back and forth along the laser principal optical axis based on the image output by the visual positioning element.

[0007] Preferably, the clamping mechanism includes a lifting adjustment component and a support block. The support block is mounted on the frame via the lifting adjustment component and has a bearing portion for placing the shoe last.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figure 1 As shown, the present invention provides a shoe last marking line processing device, including a frame 1, a clamping mechanism 2, a visual positioning element 4, and a marking mechanism 3. The frame 1 is used to install and support the various components, the clamping mechanism 2 is used to fix and clamp the shoe last 5, the visual positioning element 4 is used to scan and acquire the image of the shoe last 5, and the marking mechanism 3 includes a laser output unit 31 and a focusing lens group 32. The laser output unit 31 is used to output an initial laser, and the focusing lens group 32 is arranged in the optical path of the laser output unit 31 to receive the initial laser and output the marking laser. The focusing lens group 32 is electrically connected to the control system and the visual positioning element 4. The control system is used to control the focusing lens group 32 to achieve focusing adjustment according to the image of the shoe last 5, so that the light spot of the marking laser moves on the surface of the shoe last 5. By cooperating with the laser output element 31 and the focusing lens group 32, the laser output by the laser output element 31 can move in space after being focused and adjusted by the focusing lens group 32, so that the required pattern can be printed on the curved shoe last 5. During this process, the shoe last 5 can remain in a fixed state, which can simplify the overall structure and reduce the cost of use.

[0019] The visual positioning element 4 can be a 3D structured light camera, which can acquire and process the spatial surface information of the shoe last 5. That is, through the visual positioning element 4, the relevant systems in the control system can obtain the spatial position information and surface position of the shoe last 5. Then, by comprehensively calculating the marking parameters input into the system, the control system can ultimately control the laser output element 31 and the focusing lens group 32 to emit a beam of specified energy towards the designated spatial position, thereby achieving marking on the shoe last 5. The visual positioning element 4 can also be other image acquisition devices with three-dimensional structure recognition and processing functions. Furthermore, regarding the specific structure or principle of the control system, control systems capable of processing three-dimensional images and responding according to input requirements (such as marking parameters) are already relatively mature existing technologies. Those skilled in the art should be able to develop and design such systems, or select and purchase suitable products from existing offerings; therefore, further details are omitted here.

[0020] In one preferred embodiment, the focusing lens group 32 includes an X-axis galvanometer, a Y-axis galvanometer, and a Z-axis galvanometer. The X-axis, Y-axis, and Z-axis galvanometers are all connected to a driving mechanism. The driving mechanism is electrically connected to the aforementioned visual positioning element 4 and the control system. The control system can control the movement of the driving mechanism, thereby controlling the X-axis and Y-axis galvanometers to deflect around their axes, thereby adjusting the angle of the initial laser in the plane, i.e., adjusting the position of the initial laser spot in the horizontal plane, and controlling the Z-axis galvanometer to move back and forth along the main laser axis, thereby changing the laser beam divergence angle to achieve Z-axis focal length adjustment, i.e., adjusting the position of the initial laser spot in the vertical direction. Through the adjustment of the initial laser by the X-axis, Y-axis, and Z-axis galvanometers, it is transformed into a marking laser that can illuminate a designated position on the shoe last 5, thereby achieving marking on the shoe last 5. The X-axis and Y-axis galvanometers can be selected as high-reflectivity laser mirrors, while the Z-axis galvanometer can be a focusing lens. The arrangement order of the X-axis and Y-axis galvanometers can be interchanged. The Z-axis galvanometer should be positioned upstream of the X-axis and Y-axis galvanometers to ensure that its forward and backward movement direction is completely consistent with the laser beam path. After being focused by the Z-axis galvanometer, the laser beam is then deflected and adjusted by the X-axis and Y-axis galvanometers to obtain a spot that falls on a specific position on the shoe last 5. The X-axis galvanometer has a vertically extending X-axis, around which it deflects. The Y-axis galvanometer has a horizontally extending Y-axis, perpendicular to the X-axis, around which it deflects. This allows the X-axis and Y-axis galvanometers to adjust the position of the spot in the horizontal plane. The Z-axis galvanometer moves forward and backward along the main laser beam axis.

[0021] In one preferred embodiment, the driving mechanism includes an execution component and a reset component. The execution component includes a first power source, a second power source, and a third power source, which are used to drive the X-axis and Y-axis galvanometers to deflect and to drive the Z-axis galvanometer to displace, respectively. The reset component includes reset springs connected to the X-axis, Y-axis, and Z-axis galvanometers, respectively. By controlling the operation of the first, second, and third power sources through the control system, each galvanometer can produce corresponding actions. By setting the reset springs, the range of motion of the galvanometers can be limited, and the galvanometers can return to their initial positions without external forces.

[0022] The first and second power sources can be structured with stator magnetic circuits and rotor moving coil assemblies as the main components. Permanent magnets are fixed inside the stator magnetic circuit to form a stable and uniform radial constant magnetic field, which serves as the basic magnetic field for electromagnetic torque. The driver supplies DC control current to the rotor moving coil winding. The energized coil cuts magnetic field lines in the stator magnetic circuit, generating electromagnetic driving torque. The electromagnetic torque drives the rotor and the lens to deflect, thus realizing the deflection of the X-axis and Y-axis galvanometers. By controlling the input current parameters, a highly accurate electromagnetic driving torque can be obtained, thereby controlling the X-axis and Y-axis galvanometers to perform precise deflection and ensuring the performance. The third power source can be a combination of a servo motor and a crank-connecting rod-slider transmission mechanism. The motor's small angular displacement is converted into linear translation of the lens along the optical axis through the crank-slider mechanism, converting rotational oscillation into linear motion along the optical axis.

[0023] like Figure 3 and Figure 4 As shown, in one preferred embodiment, the clamping mechanism 2 includes a support block 21 and a lifting adjustment assembly 22. The support block 21 is mounted on the frame 1 via the lifting adjustment assembly 22. The support block 21 has a bearing portion for placing the shoe last 5. The bearing portion can be V-shaped or U-shaped, and its supporting surface can adapt to the curved structure of the shoe last 5 to achieve more stable placement and support. Clamping plates can also be provided on one or more sides of the bearing portion along the horizontal direction. The clamping plates can approach and clamp the shoe last 5, which can prevent the shoe last 5 from shifting due to external environmental interference and ensure the marking quality.

[0024] like Figure 4 As shown, the support block 21 includes a first support block 211 and a second support block 212. The top of both the first support block 211 and the second support block 212 has a V-shaped or U-shaped support structure, and the first support block 211 and the second support block 212 are at a certain angle, so that the shoe last can be placed stably between the first support block 211 and the second support block 212 at various angles, which makes it easier to fix the shoe last 5 and perform marking processing.

[0025] like Figure 4 As shown, a lifting rail 221 is provided on the lifting adjustment assembly 22. The first support block 211 and the second support block 212 are installed on the lifting rail 221 by screws (such as Torx screws that are easy to tighten by hand). In actual use, the operator can loosen the screws and then adjust the height and angle of the first support block 211 and the second support block 212 so that the shoe last 5 can be placed on the first support block 211 and the second support block 212, and so that the part of the shoe last 5 that needs to be marked faces the marking mechanism 3 and the visual positioning element 4, which is more convenient for actual use.

[0026] like Figures 1 to 5As shown, in one preferred embodiment, two or more marking stations are arranged side by side on the frame 1 (two are shown in the figure). Each marking station is equipped with a clamping mechanism 2. By setting multiple marking stations, multiple shoe lasts 5 can be placed on the frame 1 at the same time, thereby enabling simultaneous image acquisition, marking or installation of multiple shoe lasts 5, thus improving production efficiency.

[0027] Furthermore, in one preferred embodiment, the visual positioning element 4 can rotate around an axis or move along the arrangement direction of the marking stations, so that the image acquisition end of the visual positioning element 4 is aligned with different marking stations. Alternatively, multiple visual positioning elements 4 can be arranged on the frame 1, each corresponding to a different marking station. With these arrangements, images of shoe lasts 5 at multiple marking stations can be acquired simultaneously or sequentially, thereby enabling the processing of multiple shoe lasts 5. In addition, the visual positioning element 4 can also identify multiple shoe lasts 5 in other ways, for example, by having multiple lenses on the visual positioning element 4, each lens corresponding to a different marking station, etc.

[0028] Similarly, the marking mechanism 3 can rotate around the axis or move along the arrangement direction of the marking stations so that the marking laser output unit 31 and the focusing lens group 32 can be aligned with different marking stations, or the marking mechanism 3 can correspond to different marking stations and vision positioning elements 4 respectively. In actual use, although the focusing lens group 32 can adjust the optical path direction of the marking laser, it is a slight adjustment, which is not enough to make the marking laser cover multiple marking stations. Therefore, by setting the marking mechanism 3 to be movable as a whole, or by setting a marking mechanism 3 corresponding to the number of marking stations, the marking mechanism 3 can complete the marking work on the shoe lasts 5 at different stations.

[0029] like Figure 2As shown, in one preferred embodiment, a protective plate 12, a first slide rail 13, and a second slide rail 14 are provided on the frame 1. The extending directions of the first slide rail 13 and the second slide rail 14 are parallel to the arrangement direction of the multiple marking stations. The visual positioning element 4 is movably mounted on the first slide rail 13 via a connecting plate 41, and the marking mechanism 3 is also movably mounted on the second slide rail 14. That is, the visual positioning element 4 and the marking mechanism 3 are movably mounted on the slide rails, so that the visual positioning element 4 and the marking mechanism 3 reciprocate on the frame 1 along the arrangement direction of the marking stations, so that the visual positioning element 4 and the marking mechanism 3 can work for different marking stations respectively. A protective plate 12 is disposed below the visual positioning element 4 and the marking mechanism 3. The protective plate 12 has several first slots 121 and second slots 122. The first slots 121 are used to engage with the visual positioning element 4, and the second slots 122 are used to engage with the marking mechanism 3. That is, when the visual positioning element 4 and the marking mechanism 3 move on the slide rail to the positions corresponding to the first slots 121 or the second slots 122, they precisely correspond to the marking station. This ensures the normal operation of the visual positioning element 4 and the marking mechanism 3 while providing a certain degree of protection for their internal structures. Furthermore, as... Figure 5 As shown, a protective cover 16 is also provided on the outside of the visual positioning element 4 and the marking mechanism 3. The protective cover 16 is fastened to the protective plate 12, which can provide good protection for the internal components and reduce the influence of stray light in the environment on the visual positioning element 4 and the marking mechanism 3. As for the movement of the visual positioning element 4 and the marking mechanism 3 on the first slide rail 13 and the second slide rail 14, it can be realized by existing driving components such as servo motors or cylinders, which will not be described in detail here.

[0030] like Figure 2 and Figure 3 As shown, in one preferred embodiment, a partition plate 11 is provided on the frame 1. The visual positioning element 4 and the marking mechanism 3 are both located on the upper side of the partition plate 11, and the clamping mechanism 2 is located on the lower side of the partition plate 11. The partition plate 11 has a through hole 111 for aligning the clamping mechanism 2. The through hole 111 is used to accommodate the shoe last 5, such as... Figure 3 As shown, the through-hole 111 has a curved inner surface, allowing the shoe last 5 to fit snugly against the inner surface of the through-hole 111. Furthermore, as... Figure 3 As shown, a conversion plate is also fitted inside the partition plate 11, and a through hole 111 is opened on the conversion plate. The conversion plate and the partition plate 11 are detachable, so that different sizes of conversion plates can be replaced on the partition plate 11 to fit different shapes of shoe lasts.

[0031] Furthermore, such as Figure 3As shown, the partition plate 11 is mounted on the frame 1 via the lifting base 23, allowing the positions of the partition plate 11 and the through hole 111 (and the conversion plate) to be adjusted up and down. That is, the partition plate 11 can move up and down relative to the clamping mechanism 2. Thus, after the shoe last 5 is clamped by the clamping mechanism 2, the length of the part of the shoe last 5 protruding from the through hole 111 can be adjusted by adjusting the vertical position of the partition plate 11. This allows the clamping mechanism 2 and the through hole 111 to accommodate more sizes of shoe lasts 5, improving the convenience of use.

[0032] In one preferred embodiment, a shielding plate is also provided at the through hole 111 on the partition plate 11. When the shoe last 5 is placed in the through hole 111, the shielding plate is provided to block the gap between the shoe last 5 and the through hole 111. By providing the shielding plate, the influence of stray light at the gap between the shoe last 5 and the through hole 111 on the visual recognition element 4 can be reduced, thereby improving the accuracy of the visual recognition element 4 in scanning and recognizing the shoe last 5, and thus improving the marking effect on the shoe last 5.

[0033] In addition to the above embodiments, a heat dissipation system can be installed on the frame 1. This system can be an exhaust fan or similar device, which dissipates the heat generated by laser marking and also quickly removes fine powder and damaged fibers produced during marking on the shoe last 5, preventing them from adhering to the shoe last 5 and affecting product quality. A chassis 17 is installed on one side of the frame 1. A computer can be installed inside the chassis 17, containing the aforementioned control system. This system processes the image information acquired by the visual recognition element 4 and controls the operation of electrical components such as the visual positioning element 4 and the marking mechanism 3. A display screen 18 is installed on the chassis 17, with control buttons on one side. Operators can obtain current work information by observing the display screen 18 and adjust the operation of the marking device accordingly using the control buttons.
