Description

Seamless bonding method for outsole of leather shoe Technical Field The application belongs to the technical field of leather shoe processing, and particularly relates to a seamless bonding method for soles of leather shoes. Background The seamless bonding of the outsole of the leather shoe refers to a bonding process that uses adhesive to bond the sole and the upper of the leather shoe so that the bonding position of the sole and the upper has no obvious seam or seam line. The seamless bonding of the outsole of the leather shoe is generally carried out by polishing the bonding surface between the upper and the sole, then coating a proper amount of polyurethane glue or resin soft glue on the bonding surface between the upper and the sole, and finally carrying out pressurizing and thermosetting on the upper and the sole after the glue coating is carried out, thus finally completing the bonding of the outsole of the leather shoe. Because of the consumer upgrading of modern life and the pursuit of modern people for quality, the pursuit of male consumers for quality life and the personalized requirements of male consumers, compared with the industrial leather shoes produced by industrial assembly line operation, the manual leather shoes are more in line with the pursuit of modern male consumers and the requirement of consumption. In the related art, in the manual leather shoe manufacturing process, the manual polishing depends on experience judgment of a craftsman, the craftsman is required to polish the sole bonding surface through tools such as sand paper, files and the like, and the polishing degree of different functional areas (such as a half sole, a heel and a shoe waist) can be adjusted in a targeted manner, but the manual polishing cannot ensure that the sole bonding surfaces of different batches have the same polishing degree in the same functional area, so that after the polished upper sole is pressurized and thermoset, different bonding strengths exist between different functional areas, and the different areas have different bonding strengths, so that gaps are generated due to insufficient bonding strength of one area. Disclosure of Invention The embodiment of the application provides a seamless bonding method for leather shoe soles, which can improve the problem that gaps are generated in manual leather shoes because the glue coating amount cannot be adapted to polishing differences in different areas of the leather shoe soles caused by manual polishing when the polished manual leather shoes are bonded. In a first aspect, an embodiment of the present application provides a method for seamless adhesion of a outsole of a leather shoe, including: The method comprises the steps of obtaining a first image and a second image, wherein the first image is used for reflecting the surface image of a first object subjected to standard polishing operation, the second image is used for reflecting the surface image of a second object subjected to polishing operation, and the first object and the second object are all soles of leather shoes produced in the same batch; determining a plurality of transition areas based on the first image and the second image, wherein the transition areas are used for reflecting the transition areas among different functional areas in the second object; Determining a polishing degree change based on the plurality of transition areas, the first image and the second image, wherein the polishing degree change is used for reflecting the polishing degree change between the first object and the second object in different characteristic areas; And when the polishing degree change has at least one data which is not 0, determining an adjustment parameter based on the first image and the second image, wherein the adjustment parameter is used for reflecting the adjustment gluing amount when the second object is glued. The technical scheme provided by the embodiment of the application at least has the following technical effects: According to the seamless bonding method for the outsole of the leather shoe, the surface image used for reflecting the surface image of the first object after standard polishing operation and the second image used for reflecting the surface image of the second object after polishing operation are obtained in advance, the transition area used for reflecting the second object between different foot functional areas is determined according to the first image and the second image, then the change used for reflecting the polishing degree between the first object and the second object is determined according to the transition areas, the first image and the second image, and when at least one data which is not 0 exists in the polishing degree change, the adjusting parameter used for reflecting the adjusting gluing amount used for bonding the second object is determined based on the first image and the second image.
