Description

Technical Field

[0001] This invention relates to the field of shoe manufacturing equipment technology, specifically an automated shoe sole gluing device. Background Technology

[0002] Applying adhesive to the sole is a crucial step in shoe manufacturing, directly impacting the final quality and lifespan of the shoe. Traditionally, this process is done manually or with semi-automatic equipment. This method is not only inefficient but also prone to waste due to inaccurate control over the amount of adhesive used. With technological advancements and increased automation, fully automated sole gluing machinery has become a focus of research and development in the industry.

[0003] Most existing automated sole gluing solutions employ robotic arms supplemented by programmable control systems to apply glue along preset trajectories. While such equipment represents a significant improvement over traditional manual gluing, it still has several shortcomings. For example, existing devices have limited gluing speeds, and the limitations of the robotic arm's operating speed prevent a substantial increase in the efficiency of the gluing process. Furthermore, robotic gluing systems typically require programming settings for soles of different shapes and sizes, resulting in significant time spent on adjustments when switching between different shoe models, thus reducing production flexibility.

[0031] Please see Figure 2 and Figure 3As shown, the top of the dispensing head 7 is connected to the bottom of the glue storage tube 6 via a flexible hose 17. A second fixing cylinder 18 is also provided inside each corner of the bottom surface of the mounting bracket 11. The second fixing cylinder 18 is located inside the first fixing cylinder 23. A connecting rod 19 is slidably embedded inside the bottom end of each second fixing cylinder 18. The bottom end of the connecting rod 19 is connected to the top surface of the dispensing head 7 via a universal joint 20.

[0032] Please see Figure 2 and Figure 4 As shown, the first fixing cylinder 23 on the upper left side is connected to the second fixing cylinder 18 on the lower right side; the first fixing cylinder 23 on the lower left side is connected to the second fixing cylinder 18 on the upper right side; the first fixing cylinder 23 on the upper right side is connected to the second fixing cylinder 18 on the lower left side; and the first fixing cylinder 23 on the lower right side is connected to the second fixing cylinder 18 on the upper left side.

[0033] The working principle of this embodiment is as follows:

[0034] The device transports the shoe sole to be processed via conveyor belt 1. First, the vision sensing device 2 scans and analyzes the position and geometry of the shoe sole and sends the data to the processor. The processor analyzes the received data to determine the glue application points and controls the opening of the electronically controlled valves 10 on each glue application component 5 corresponding to these points. When the shoe sole is transported to the bottom of the lifting frame 4, the lifting frame 4 first descends to reduce the gap between the glue application head 7 and the shoe sole. Then, the air pump works to introduce high-pressure gas into the main air pipe. The high-pressure gas enters the corresponding glue storage pipe 6 through the branch air pipe opened by the electronically controlled valve 10. Thus, the glue inside is pushed out of the glue application head 7 by air pressure and sprayed directly onto the shoe sole to complete the glue spraying work.

[0035] Because the edge of the sole has a certain curvature, in order to achieve precise glue spraying on this curved surface, the glue application component 5 is pressed down by the lifting frame 4. At this time, the support rods 13 around the glue dispensing head 7 will first contact the sole. If the glue dispensing point is a flat surface, each support rod 13 will move upward synchronously, thereby driving the connecting rod 19 downward through the sealing cylinder 21 under the action of air pressure difference. Thus, the glue dispensing head 7 will descend synchronously through the four connecting rods 19, contacting the sole surface to perform the glue spraying operation. When the glue dispensing point is a curved surface, such as an arc surface that is higher on the left and lower on the right, the glue application component 5 is pressed down. During pressing, due to the height difference between the left and right sides, if the pressing distance of the lifting frame 4 is constant, the upward movement distance of the left support rod 13 will be greater than the upward movement distance of the right support rod 13. Since the left support rod 13 is connected to the right connecting rod 19, the downward movement distance of the right connecting rod 19 will be greater than the downward movement distance of the left connecting rod 19. This causes the universal joint 20 to push the dispensing head 7 to turn to the left, allowing the dispensing head 7 to directly spray glue onto the curved surface. After the dispensing work is completed, the connecting rod 19 will be reset under the rebound force of the return spring 16 after the lifting frame 4 rises, ready for the next work.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
