A heel backer shaper comprises a case, a last-compressing ironing base, a last rotation mechanism, a shaping wheel, an automatic selector switch, and a footboard. One side of the upper half of the case is not closed. The last rotation mechanism is disposed on the upper half of the case. The last rotation mechanism comprises a cylinder and a rotary table; the rotary table is disposed at the top of the cylinder; the last-compressing ironing base is disposed on the top inner wall of the case and right faces the rotary table. During heel shaping, the heel backer shaper can adjust the operating performances, such as the position of the shaping wheel on a backer, knocking force, ironing temperature and delay time, according to the quality conditions of a shoe so as to acquire optimal shaping effect; during normal working, the heel backer shaper can operate in an automatic manner; an electrothermal plate on the last-compressing ironing base is controlled via a three-compartment closed-loop controlled silicon voltage regulator, temperature control precision is greatly improved, a temperature difference can be controlled within a 10 DEG C range, and the plane of the shaped backer is flat, with clear edge and smooth wrinkle-free surface.

A multiple camera vision system captures discrete images having overlapping fields of view. Each of the cameras is calibrated and the images from the cameras are stitched together as a stitched image. A stitched image from the multiple cameras is then used in a calibration process to prepare the multiple camera vision system to be used in connection with a processing operation. A stitched image is used as an input for identifying a feature of the material and for determining a tool path for the material. The tool path determined with the stitched image is provided to a process station to perform an operation on the material.

Method for manufacturing shoe uppers, comprising: Step A: Providing materials for shoe uppers, wherein a laser cutting machine (1) is put into operation, whereupon a whole roll of shoe material and thermoplastic elastomer is placed onto a spool material rod (11) of the laser cutting machine (1), wherein a feeding device (12) is located above the spool material rod (11), whereupon the shoe material and the thermoplastic elastomer are transported by the feeding device (12) to a laser cutting platform (13), and wherein the pre-made pattern image file for the shoe upper is entered into a main control computer of the laser cutting machine (1), so that a laser head (14) of the laser cutting machine (1) cuts the shoe material and the thermoplastic elastomer, and wherein the shoe material and the thermoplastic elastomer are conveyed via a conveyor belt to a finished product area after cutting.while the remaining waste material is transported to the waste area via another conveyor belt after cutting; Step B: Molding of shoe uppers, wherein a shoe upper molding machine (2) is put into operation, the shoe upper molding machine (2) being provided with a single upper mold (21) and several sub-molds (22), and wherein a shoe upper mold template is placed on the sub-mold (22), the heating temperature and heating time of the upper mold (21) and the sub-mold (22) are each set, and during the heating process the heat energy of the sub-mold (22) is transferred to the shoe upper mold template, and wherein an air compressor is put into operation, wherein, after it has been confirmed that the temperature of the sub-mold (22) has reached the set heating temperature, the shoe material and the thermoplastic elastomer provided in the end-product area are placed on the shoe upper mold template, and wherein a vacuum silicone cover plate (23) covers the sub-mold (22) to block the air.whereupon a negative pressure vacuum device for the lower mold (22) begins to operate to extract the excess air in the lower mold (22), so that the shoe material and the thermoplastic elastomer can maintain a stable and flat state on the upper mold template, whereupon the lower mold (22) is moved under the upper mold (21), the upper mold (21) being lowered and engaged with the lower mold (22), and the shoe material and the thermoplastic elastomer being heated by the upper mold (21) and the lower mold (22) until the set time is reached, so that the shoe material and the thermoplastic elastomer are thermally melted and fused together at the set temperature to form a multi-layered shoe material composite (3) with a designed upper pattern, and the upper mold (21) is automatically lifted.wherein the sub-mold (22) automatically moves back to its original position to dissipate heat and perform demolding, and wherein while waiting for heat to dissipate from the sub-mold (22), the other sub-mold (22) can automatically repeat the above steps, and wherein when the heat dissipation time of the sub-mold (22) is reached, the vacuum silicone cover plate (23) is cooled, wherein after lifting the vacuum silicone cover plate (23), the multi-layered shoe material composite (3) can be continuously cooled, and wherein after cooling is complete, demolding is performed, and wherein the molded and bonded multi-layered shoe material composite (3) is fed to a laser machine in preparation for the next step; , Step C: Processing of shoe uppers, wherein the laser machine is put into operation, wherein the laser machine is used to perform operations such as air perforation, trimming of rough edges and cutting of waste materials, wherein the multilayer shoe material composite (3) is transported to a printing machine in preparation for the next step; Step D: Printing of shoe uppers, wherein the printing machine is put into operation, whereupon the multilayer shoe material composite (3) is placed on the printing platform of the printing machine for printing, and wherein, after the printing process is completed, the multilayer shoe material composite (3) is removed as a finished product.
