At the same time, a connecting shaft 12 is provided at the upper end of the shoe last jig 11. The outer wall of the connecting shaft 12 is recessed with an annular connecting groove 121, and the side wall of the shoe last jig 11 is also provided with a positioning groove 111.

[0035] The above-mentioned shoe last scanning and marking device includes a machine 20, a scanning mechanism 30, a marking mechanism 40 and a gripping mechanism 50. The scanning mechanism 30 includes a supporting platform 31 fixed to the upper end of the machine 20, and a scanning module 32 arranged on the side of the supporting platform 31. The marking mechanism 40 includes a marking module 41 arranged on the side of the supporting platform 31, and the marking module 41 is used to mark the shoe last 10. The gripping mechanism 50 includes a connecting frame 51 fixed to the upper end of the machine 20, a lifting module 52 fixed to one end of the connecting frame 51, and a clamp 53 driven and connected to the lifting module 52. The clamp 53 is arranged above the supporting platform 31. When in use, the clamp 53 is used to clamp the shoe last fixture 11, and the lifting module 52 is used to drive the clamp 53 to lift and lower vertically.

[0036] The working principle of the shoe last scanning and marking device involved in this utility model is as follows:

[0037] The shoe last fixture 11 is connected to the clamp 53, and the lifting module 52 drives the shoe last 10 to move downward until it is flush with the marking module 41; the marking module 41 marks the side of the shoe last 10 and prints a mark of a certain depth; after marking is completed, the lifting module 52 drives the shoe last 10 to move downward to the supporting platform 31, and the scanning module 32 scans the mark on the shoe last 10 to detect whether the marking quality meets the processing requirements.

[0038] See also Figure 1 and Figure 2 A protective cover 21 is installed at the top of the platform 20. This covers the outside of the scanning mechanism 30, marking mechanism 40, and gripping mechanism 50 to prevent environmental interference with the marking process. A cavity is provided within the platform 20 for storing electrical components. Wheels 22 are also located at the bottom of the platform 20 for easy mobility.

[0039] See also Figure 1 A bracket 33 is provided on both sides of the supporting platform 31 , and the scanning module 32 is arranged on the bracket 33 and tilted so as to align with the mark on the side of the shoe last 10 for scanning and detection.

[0040] See also Figure 3The marking mechanism 40 further includes a sliding module 42 and a movable frame 43 drivingly connected to the sliding module 42. The marking module 41 is fixed to the side of the movable frame 43 facing the support platform 31. The sliding module 42 drives the movable frame 43 toward or away from the support platform 31 to adjust the distance between the marking module 41 and the shoe last 10 to ensure marking quality. Specifically, the sliding module 42 includes a base 421, a first guide rail 422, a slider 423, and a first drive motor 424. The first guide rail 422 is fixed to the base 421. The slider 423 is slidably connected to the first guide rail 422. The first drive motor 424 is fixed to the base 421 and drivingly connected to the slider 423. The first drive motor 424 drives the screw to rotate, thereby driving the slider 423 to move along the first guide rail 422. The movable frame 43 is fixedly connected to the upper end of the slider 423.

[0041] See also Figure 3 In this embodiment, the marking module 41 includes a laser generator 411 and a marking head 412 connected to the laser generator 411. The marking head 412 is arranged horizontally and facing the supporting platform 31. The marking head 412 emits a laser to the shoe last 10 and performs laser printing on the side of the shoe last 10. In this embodiment, laser marking is adopted according to the material of the shoe last 10. It can be understood that the marking module 41 can also adopt pneumatic or electro-corrosion. Furthermore, a sensor 44 is provided on the side of the marking head 412. Since the sizes of shoe lasts are different, the focal length of the laser marking will change. Therefore, the sensor 44 is provided to sense the size of the shoe last and feed back the measurement data to the sliding module 42. The sliding module 42 adjusts the corresponding distance to ensure the quality of the laser marking.

[0042] See also Figure 4 and Figure 5 The connecting frame 51 in the gripping mechanism 50 includes a support column 511 vertically mounted on the upper end of the machine 20, a support crossbar 512 horizontally fixed to the support column 511 on the side facing the carrier 31, and a connecting plate 513 fixed to the support crossbar 512 on the side facing away from the support column 511. The lifting module 52 is fixed to the connecting plate 513. Specifically, two support crossbars 512 are provided to improve the structural strength. The lifting module 52 includes a second guide rail 521 fixed to the connecting plate 513 and placed vertically, a lifting seat 522 slidably connected to the second guide rail 521, and a second drive motor 523 mounted on the connecting plate 513 and drivingly connected to the lifting seat 522. The clamp 53 is fixed to the lifting seat 522. The second drive motor 523 drives the screw to rotate to drive the lifting seat 522 to move vertically along the second guide rail 521.

[0043] See also Figure 4The clamp 53 is provided with a connecting hole 531 with an opening at the lower end, and the inner wall of the connecting hole 531 is provided with a plurality of limiting beads 532 distributed in a circular array; when working, the connecting shaft 12 of the shoe last fixture 11 is inserted into the connecting hole 531 of the clamp 53, and the limiting beads 532 will be clamped in the connecting groove 121 to realize the connection between the shoe last 10 and the clamp 53.

[0044] See also Figure 6 , also includes a transfer mechanism 60, the transfer mechanism 60 includes a manipulator (not shown in the figure) arranged on the side of the machine 20, and a pneumatic clamp 61 connected to one end of the manipulator; the transmission end of the pneumatic clamp 61 is provided with two symmetrically distributed clamping blocks 62. When in use, the pneumatic clamp 61 drives the clamping blocks 62 to move in opposite directions to clamp the shoe last jig 11, and the manipulator drives the shoe last 10 to move; the transfer mechanism 60 is used to move the shoe last 10 from the remaining workstations to the shoe last scanning and marking device of the present invention. Specifically, a positioning ridge 63 is provided on the opposite side of the clamping block 62. When the clamping block 62 clamps the shoe last jig 11, the positioning ridge 63 cooperates with the positioning groove 111 on the side wall of the shoe last jig 11 to improve the clamping stability of the clamping block 62 and the shoe last jig 11.
