Description

Technical Field

[0001] This utility model relates to the field of laser drilling technology, and in particular to a laser drilling device for microporous breathable insoles. Background Technology

[0002] In the footwear manufacturing industry, microporous breathable insoles are widely used in various products such as sports shoes, casual shoes, safety shoes, and functional shoes because of their excellent breathability, sweat wicking, and heat dissipation properties, which can effectively improve the comfort of the wearer and reduce foot stuffiness and odor. These insoles typically require the processing of a large number of tiny, regular, and evenly distributed micropores in specific functional areas (such as the forefoot, arch, or heel). These micropores not only require precise size, complete pore shape, no burrs or carbonization, but also need to be precisely arranged according to a preset pattern or density to achieve the best air circulation and moisture removal effect, meeting the needs of different shoe designs and consumers for a high-quality wearing experience.

[0003] In shoe insole manufacturing, traditional stamping and perforation relies on specialized molds. When changing product designs, new molds need to be manufactured, resulting in high costs and long production cycles. It is particularly difficult to adapt to the production of complex, irregular, or small-batch customized patterns. Moreover, contact stamping is prone to producing burrs and indentations on the material edges, affecting product quality. Although laser perforation technology has advantages such as non-contact, high precision, and programmability, which can effectively overcome many defects of traditional stamping, existing equipment is mostly an independent single machine, lacking effective integration with automated conveying and precise positioning, resulting in low automation. At the same time, most equipment lacks a multi-axis linkage control system, which cannot achieve precise scanning of complex trajectories. As a result, when facing diverse and customized micro-hole patterns, the processing flexibility and efficiency are insufficient, and frequent manual intervention is still required, making it difficult to meet the actual needs of large-scale and intelligent production.

[0004] Therefore, it is necessary to design a laser perforation device for microporous breathable insoles to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of traditional stamping and punching, such as high changeover costs, difficulty in adapting to complex patterns, and easy material damage; and the lack of automation integration and multi-axis linkage control in existing laser punching equipment, which makes it impossible to efficiently and precisely process complex trajectories, requires a lot of manual intervention, and is difficult to meet the needs of intelligent production, this utility model provides a microporous breathable insole laser punching device.

[0006] A laser drilling device for microporous breathable insoles includes a support frame, a rotating shaft, a servo motor, a conveyor belt, molds, a support plate, a second sliding component, a third sliding component, and a laser drilling machine. The support frame has rotating shafts rotatably connected to its top left and right sides. A servo motor is fixedly connected to the right rear of the support frame, and the output shaft of the servo motor is connected to the rear end of the right rotating shaft. A conveyor belt is installed between the two rotating shafts. Multiple detachable molds are evenly installed along the length of the conveyor belt. A support plate is fixedly connected to the rear of the top of the support frame. A second sliding component is fixedly connected to the upper part of the support plate. A third sliding component is installed on the slider of the second sliding component, and a laser drilling machine is installed on the slider of the third sliding component.

[0007] Optionally, it also includes a first sliding component and a pressure plate, with the first sliding component fixedly connected to the lower front side of the support frame, and the pressure plate mounted on the slider of the first sliding component.

[0008] Optionally, it also includes a position sensor and a signal receiver, with the position sensor installed on the front side of the bottom of the pressure plate and the signal receiver installed on the front side of the top of each mold.

[0009] Optionally, it also includes a collection box, which is slidably placed on the bottom left side inside the support frame.

[0010] Optionally, it also includes a controller and a limit frame. The controller is installed on the front left side of the support frame. The controller is electrically connected to the servo motor, the first sliding component, the second sliding component, the third sliding component, the position sensor, and the signal receiver. The limit frame is installed on the top of the support frame, and the conveyor belt is rotatably connected in the middle.

[0011] Optionally, both the support frame and the limit frame are made of high-strength aluminum alloy.

[0012] The beneficial effects of this utility model are: 1. This utility model uses the second and third sliding components to control the laser drilling machine in coordination, realizing multi-axis linkage precision scanning, so that the laser head can flexibly and accurately process complex micro-hole patterns according to the preset trajectory, breaking through the limitations of traditional drilling technology and improving the flexibility, accuracy and automation level of drilling.

[0013] 2. This utility model achieves precise intermittent conveying of molds through the collaboration of servo motors and position sensors, ensuring accurate positioning, avoiding human error, and greatly improving the degree of automation, production efficiency and operational reliability.

[0014] 3. This utility model uses the first sliding component to drive the pressure plate to press down and is detected by the signal receiver, so as to achieve reliable fixation of the insole, effectively prevent displacement during drilling, ensure the accuracy of micro-holes, and improve the product qualification rate and processing stability.

[0015] 4. This utility model uses a pressure plate and a signal receiver on the mold to form a detection circuit, which confirms the pressing status in real time and ensures that drilling is started only after pressing, avoiding dry drilling or misalignment, and improving the safety, intelligence level and processing reliability of the equipment.

Detailed Implementation

[0021] Example: A laser perforation device for microporous breathable insoles, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the system includes a support frame 1, a rotating shaft 2, a servo motor 3, a conveyor belt 4, a mold 5, a support plate 6, a second sliding assembly 11, a third sliding assembly 12, and a laser drilling machine 13. The top left and right sides of the support frame 1 are rotatably connected to the rotating shaft 2. The servo motor 3 is installed on the right rear side of the support frame 1 by screws. The output shaft of the servo motor 3 is connected to the rear end of the right rotating shaft 2. A conveyor belt 4 is installed between the two rotating shafts 2. Multiple detachable molds 5 are evenly installed on the surface of the conveyor belt 4 along its length. The support plate 6 is installed on the top rear side of the support frame 1 by screws. The second sliding assembly 11 is installed on the upper part of the support plate 6 by screws. The third sliding assembly 12 is installed on the slider of the second sliding assembly 11. The laser drilling machine 13 is installed on the slider of the third sliding assembly 12.

[0022] like Figure 1 , Figure 3 and Figure 4As shown, it also includes a first sliding assembly 7, a pressure plate 8, a position sensor 9, and a signal receiver 10. The first sliding assembly 7 is installed on the lower front side of the support frame 1 by screws. The pressure plate 8 is installed on the slider of the first sliding assembly 7. The position sensor 9 is installed on the front bottom side of the pressure plate 8. The signal receiver 10 is installed on the front top side of each mold 5.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes a collection frame 14, a controller 15, and a limit frame 16. The collection frame 14 is slidably placed on the bottom left side of the support frame 1. The controller 15 is installed on the front left side of the support frame 1. The controller 15 is electrically connected to the servo motor 3, the first sliding component 7, the second sliding component 11, the third sliding component 12, the position sensor 9, and the signal receiver 10. The limit frame 16 is installed on the top of the support frame 1. The conveyor belt 4 is rotatably connected in the middle. Both the support frame 1 and the limit frame 16 are made of high-strength aluminum alloy.

[0024] When using this equipment, firstly, preparation work is carried out, including checking the stability of the equipment, loading or setting the punching program in the controller 15, and placing the insoles to be processed one by one into the molds 5 on the conveyor belt 4. The molds 5 are detachably connected to the conveyor belt 4 by bolts, which facilitates the replacement of molds with different insole groove types. After starting the equipment, the output shaft of the servo motor 3 drives the rotating shaft 2 to rotate, thereby driving the conveyor belt 4 to run, smoothly and accurately conveying the molds 5 loaded with insoles to the discharge end. When the first mold 5 runs to the predetermined processing position directly below the pressure plate 8, the position sensor 9 detects that the mold 5 has arrived in place and sends a signal to the controller 15. Upon receiving the signal, conveyor belt 4 automatically stops to ensure accurate positioning. Subsequently, the first sliding component 7 drives the pressure plate 8 to move downwards, firmly pressing the insole in mold 5 to prevent displacement or vibration during the drilling process and ensure processing accuracy. After the pressure plate 8 is pressed into place, the signal receiver 10 is triggered, sending a "pressed in place" signal to the controller 15. After confirming the signal, the controller 15 immediately starts the laser drilling machine 13 and simultaneously issues commands to precisely control the second sliding component 11 and the third sliding component 12. At this time, the laser drilling machine 13 enters the working state: the second sliding component 11 (controlling the forward and backward direction) and the third sliding component 12... (Controlling left and right directions) Under the precise commands of the controller 15, the laser head coordinates and moves in unison to achieve high-speed, smooth synchronous motion. This allows the laser head to flexibly and accurately complete micro-hole processing on the entire surface of the insole along a preset complex path. After drilling, the second sliding component 11 and the third sliding component 12 quickly reset, and the laser drilling machine 13 stops working. Subsequently, the controller 15 commands the first sliding component 7 to lift the pressure plate 8, releasing the processed insole. The conveyor belt 4 restarts, moving the drilled insole along with the mold 5 towards the discharge end, while simultaneously feeding the next insole to be processed into the workstation, achieving continuous cyclic operation. When the mold 5 is running... Upon reaching the discharge end, the operator removes the finished insoles from the mold 5 and places them into the collection box 14 for centralized storage. The collection box 14 is not only used to orderly store finished products to avoid mixing and damage, but also facilitates subsequent counting, transfer and quality inspection. During the entire operation, the limit frame 16 ensures that the conveyor belt 4 does not shift laterally. The support frame 1 and the limit frame 16, made of high-strength aluminum alloy, provide a lightweight and stable structural foundation, effectively absorbing processing vibrations and ensuring the accuracy and reliability of the equipment during long-term operation. The mold 5 needs to be cleaned regularly and the equipment status needs to be checked to maintain efficient and stable production. After use, the power should be turned off in time.
