[0038] like Figures 1 to 8The diagram illustrates an embodiment of this utility model, relating to an outsole glue spraying system. It is characterized by comprising a lifting mechanism 10, an upper tooling plate 20, a transfer mechanism 30, and a glue spraying mechanism 40. The lifting mechanism 10 includes a lifting plate 11 and a first lifting pin 12 connected to the lifting plate 11. The lifting plate 11 is used to lift the upper tooling plate 20, and the first lifting pin 12 is used to engage with the upper tooling plate 20 to fix its position. The upper tooling plate 20 is used to carry the shoe material 21 to be processed. The transfer mechanism 30 includes a transfer slide plate 31 and a second lifting pin 32 connected to the transfer slide plate 31. The transfer slide plate 31 is used to drive the upper tooling plate 20 to move, and the second lifting pin 32 is used to engage with the upper tooling plate 20. The glue spraying mechanism 40 is used to perform glue spraying operations on the shoe material 21 carried by the upper tooling plate 20. Specifically, the upper tooling plate 20 is stably lifted and positioned by the lifting plate 11 and the first lifting pin 12 to ensure the accuracy of the glue spraying reference surface; the transfer slide plate 31 and the second lifting pin 32 of the transfer mechanism 30 are used to achieve smooth movement of the tooling plate to avoid positional deviation caused by the shaking of the shoe material 21 during transportation; and a glue spraying mechanism 40 is set up to accurately spray glue onto the positioned shoe material 21 to ensure that the glue spraying trajectory matches the shoe shape.

[0039] like Figure 1 and Figure 2 As shown, the number of lifting mechanisms 10 is set to two, and each lifting mechanism 10 includes a lifting cylinder 13 and guide rods 14. The lifting cylinder 13 is used to drive the lifting plate 11 to rise and fall. There are four guide rods 14, which are connected to the four corners of the lifting plate 11 and are movably connected to the working platform 71. Specifically, a double lifting mechanism 10 is set to realize parallel glue spraying at two workstations; the lifting cylinder 13 provides a stable driving force to ensure consistent lifting height; the four guide rods 14 set at the four corners restrict the movement trajectory of the lifting plate 11, eliminate lateral deviation, and improve the accuracy of repeated positioning.

[0040] like Figure 3 and Figure 4As shown, the bottom of the upper tooling plate 20 is provided with a plurality of first holes 22, and a second hole 23 is provided between two adjacent first holes 22; the first holes 22 and the second holes 23 are respectively connected to the first lifting pin 12 and the second lifting pin 32. Specifically, the multi-level hole layout of the upper tooling plate 20 realizes hierarchical positioning. The first holes 22 are set to cooperate with the lifting mechanism 10 to realize the coarse positioning of the tooling plate; the second holes 23 are set to cooperate with the transfer mechanism 30 to complete the precise positioning; through the stepped positioning method, the positioning accuracy of the upper tooling plate 20 is effectively improved, ensuring that the glue spraying reference surface of the shoe material 21 is consistent; in some embodiments, the upper tooling plate 20 is provided with a fixing component for fixing the shoe material 21 to be processed, so as to avoid the shoe material 21 moving and affecting the processing.

[0041] like Figure 5 As shown, the number of transfer mechanisms 30 is set to two, and each transfer mechanism 30 includes a transfer linear module 33. The transfer linear module 33 is used to drive the upper tooling plate 20 on the transfer slide plate 31 to the glue spraying mechanism 40. Specifically, the two transfer mechanisms 30 work together to simultaneously perform the transfer tasks of loading, unloading and glue spraying, reducing equipment standby time and realizing parallel processing of the glue spraying process. In some embodiments, the transfer linear module 33 is an existing linear module, the structure and model of which will not be described in detail. Moreover, this existing product technology is mature, easy to maintain, and greatly improves production efficiency and system reliability.

[0042] like Figure 5 and Figure 6 As shown, a dust removal device 50 is provided above the transfer linear module 33. The dust removal device 50 includes a U-shaped dust removal plate 51 and a support column 52. The inner side of the U-shaped dust removal plate 51 has an inclined surface 53, and the inclined surface 53 has dust removal holes 54. The support column 52 is connected to the U-shaped dust removal plate 51 and the working platform 71 respectively. Specifically, the inclined surface 53 and dust removal holes 54 of the U-shaped dust removal plate 51 are designed to increase the coverage area of ​​the shoe material 21 surface. The inclined angle generates a spiral airflow, which enhances the dust adsorption effect. It can also effectively remove impurities from the surface of the shoe material 21 before spraying glue, avoiding particles from affecting the adhesion of the glue. At the same time, it provides a clean working environment for the glue spraying operation and improves the quality of the finished product. At the same time, the dust removal device 50 can absorb excess glue, reducing glue waste and equipment cleaning frequency, and keeping the working environment clean. In some embodiments, the dust removal device 50 is connected to an existing dust removal system. The structure and model of the dust removal system will not be described in detail.

[0043] like Figure 5As shown, the glue spraying mechanism 40 includes a robotic arm 41 and a glue spraying gun 42. The robotic arm 41 is located between two transfer mechanisms 30 and is used to drive the glue spraying gun 42 to move between the two transfer mechanisms 30. The glue spraying gun 42 is connected to the robotic arm 41. Specifically, the robotic arm 41 is positioned in the center of the two transfer mechanisms 30, achieving full coverage of the workstations on both sides through six-axis linkage, reducing glue spraying blind spots. The robotic arm 41 can quickly switch workstations, driving the glue spraying gun 42 to spray glue accurately along the trajectory. Combined with the parallel operation of the two transfer mechanisms 30, it significantly improves the glue spraying efficiency and coverage per unit time. In some embodiments, the robotic arm 41 is an existing multi-axis robotic arm 41, the structure and model of which will not be described in detail. The glue spraying gun 42 is externally connected to a glue pipe to achieve glue supply.

[0044] like Figure 5 As shown, a cleaning device 60 for cleaning the glue spray gun 42 is provided on one side of the robotic arm 41, and an electrically heated constant-temperature water bath 61 for softening the glue in the nozzle of the glue spray gun 42 is provided on one side of the cleaning device 60. Specifically, the cleaning device 60 automatically completes the rapid cleaning of the glue spray gun 42 to prevent the glue from hardening and clogging the nozzle, thus extending the service life of the equipment; the electrically heated constant-temperature water bath 61 is set up to soften the residual glue by immersing the nozzle of the glue spray gun 42 in warm water, thereby improving the cleaning effect.

[0045] like Figure 7 As shown, the cleaning device 60 includes a cleaning tank 62, a drive motor (not shown), a rotating shaft 63, a mounting bracket 64, and a cleaning brush 65. The cleaning tank 62 is positioned above the work platform 71 and has a drain hole 66. The drive motor (not shown) drives the rotating shaft 63. The rotating shaft 63 is connected to the mounting bracket 64, which mounts the drive motor (not shown). The cleaning brush 65 is connected to a cleaning nozzle (not shown). Specifically, the drive motor (not shown) drives the cleaning brush 65 to rotate at high speed, combined with the high-pressure rinsing of the cleaning nozzle (not shown), to achieve comprehensive cleaning of the inner and outer walls of the glue gun 42, ensuring no glue residue. The drain hole 66 of the cleaning tank 62 promptly discharges waste liquid, preventing secondary pollution and further improving the cleaning effect and equipment maintenance efficiency.

[0046] like Figure 1 and Figure 5 As shown, the system also includes a frame 70, which is connected to a work platform 71. The work platform 71 is connected to the lifting mechanism 10, the transfer mechanism 30, and the vision scanning mechanism 80. Specifically, the frame 70 provides rigid support for the system, ensuring the flatness and stability of the work platform 71, reducing the interference of equipment vibration on the glue spraying accuracy, and providing installation for control systems such as industrial computers and control panels, thereby improving the overall control reliability of the system. The work platform 71 facilitates the installation and debugging of each mechanism.

[0047] like Figure 1 As shown, it also includes a visual scanning mechanism 80, which includes a gantry frame 81, a scanning line module 82, and a scanning camera 83. The gantry frame 81 is straddling the work platform 71 and positioned above the transfer mechanism 30. The scanning line module 82 is connected above the gantry frame 81 and is used to drive the scanning camera 83 to translate. The scanning camera 83 is used to scan the shoe material 21 to be processed to generate a glue spraying trajectory. Specifically, the gantry frame 81 and the scanning line module 82 drive the scanning camera 83 to scan the shoe material 21 from multiple angles, and the collected data is processed by an algorithm to automatically generate a glue spraying trajectory. Compared with manual scanning, this method significantly improves the efficiency and accuracy of path planning, can quickly adapt to different shoe types, and enhances the intelligence and process flexibility of this invention.

[0048] The working principle of this utility model is as follows:

[0049] When the outsole glue spraying system is running, the upper tooling plate 20 carries the shoe material 21 to be processed and conveys it to the lifting mechanism 10. The lifting cylinder 13 drives the lifting plate 11 to rise, and the first lifting pin 12 is inserted into the first hole 22 on the edge of the tooling plate to complete the coarse positioning. Then, the transfer mechanism 30 moves to below the upper tooling plate 20, the second lifting pin 32 is inserted into the second hole 23 in the center, and the lifting mechanism 10 descends to transfer the upper tooling plate 20 to the transfer mechanism 30. The transfer mechanism 30 transports the upper tooling plate 20 to below the vision scanning mechanism 80 through the transfer linear module 33. The scanning camera 83 collects data of the shoe material 21 from multiple angles and generates a glue spraying trajectory, and then transports it to the glue spraying station. The robot arm 41 located between the two transfer mechanisms 30 drives the glue spraying gun 42 to spray glue on the shoe material 21 according to the trajectory. The other transfer mechanism 30 can simultaneously perform loading or unloading operations. After the glue is applied, the glue gun 42 first softens the glue in the nozzle in the electric thermostatic water bath 61, and then enters the cleaning device 60, where the rotating brush works in conjunction with the nozzle to complete the cleaning. Finally, the glued tooling plate is sent back to the lifting mechanism 10 by the transfer mechanism 30, and after being lifted, it returns to the double-speed chain and enters the subsequent process. All components work together to achieve an efficient and precise outsole glue application process.

[0050] This invention utilizes the lifting plate 11 of the lifting mechanism 10 in conjunction with the first lifting pin 12, the multi-level holes of the upper tooling plate 20, and the guide rod 14 to achieve graded positioning of the tooling plate. Combined with data collected by the vision scanning mechanism 80, a glue spraying trajectory is generated, ensuring high-precision glue spraying. The dual transfer mechanism 30 can perform loading, unloading, and glue spraying tasks in parallel, and, in conjunction with the rapid station switching of the robotic arm 41 in the glue spraying mechanism 40, improves work efficiency. The cleaning function of the cleaning device 60, combined with the electric heating constant temperature water bath 61 to soften the nozzle of the glue spray gun 42, enhances the cleaning effect.

[0051] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
