Description

Automatic gluing pretreatment process and equipment for car lamp shell Technical Field The invention relates to the technical field of automobile part manufacturing, in particular to an automatic gluing pretreatment process and equipment for a lamp housing of a car lamp. Background In the automobile part manufacturing industry, a car lamp is used as a safety part of an automobile core, the assembly quality of the car lamp directly influences the driving safety, and the pressing tightness of a lamp shell and a lamp shade is one of core indexes of the assembly quality of the car lamp. In order to ensure the sealing performance of the car lamp, the sealing groove of the lamp housing is required to be uniformly coated with glue before the lamp housing is pressed with the lamp cover, and the lamp housing assembled with internal parts is required to be subjected to pretreatment operations such as dust removal, flame spraying and the like before the glue coating, wherein the dust removal operation is used for removing impurities such as dust, scraps and the like on the surface of the lamp housing and in the sealing groove to avoid the influence of the impurities on the bonding effect of the adhesive and the lamp housing, and the flame spraying operation is used for activating the plastic surface of the lamp housing to break the inertia of the plastic molecular surface, so that the bonding strength of the adhesive and the lamp housing is improved, and the sealing effect of the glue coating and the subsequent pressing is fundamentally ensured. At present, in the industry, aiming at dust removal, flame spraying and glue spreading treatment before glue spreading of a lamp shell, a single workbench dispersing operation mode is generally adopted, namely, each working procedure is respectively finished on independent workbench, and each workbench is only provided with special equipment for finishing a single working procedure, and an automatic flow-turning mechanism without linkage is adopted. In the mode, the circulation of lamp shell materials among all working procedures is completely carried and placed by operators, and is limited by the operation flow, at least 3 operators are required to finish the work of material circulation, auxiliary operation of all working procedures and the like, so that the labor cost investment of enterprises is greatly increased, and the problems of lamp shell collision, displacement and the like are easily caused in the material circulation process due to subjectivity and uncertainty of manual operation, and the appearance and assembly precision of the lamp shell are affected. Meanwhile, because each procedure involves manual close-range operation equipment, a large number of safety detection measures and protection devices, such as a grating, an emergency stop button, a safety protection cover, an anti-false touch detection module and the like, are additionally arranged on each single machine equipment to ensure personal safety of operators, and the safety devices not only increase design complexity of the equipment, but also greatly improve manufacturing cost and later maintenance cost of the equipment. In addition, the beat of manual operation and material circulation is difficult to accurate control, and the operation beat of each process has obvious difference, leads to whole assembly's work beat longer, and production efficiency is low, and the equipment can't realize 24 hours uninterrupted operation, and production output is restricted. In addition, traditional unit equipment is for specific model lamp body design, and equipment structure and frock's suitability is strong, when changing the lamp body product of production different models, need dismantle by a wide margin, adjust equipment major structure, change core part even, and the product compatibility of equipment is extremely poor, can't satisfy the production demand of automobile industry multiple varieties, small batch, scale. Aiming at the defects of high labor cost, high equipment manufacturing cost, low production efficiency, poor product compatibility and the like in the prior art, the development of an automatic lamp shell gluing pretreatment process and equipment is needed to be developed, the linkage operation of each procedure and the automatic circulation of materials are realized through an automatic means, the manual participation is canceled, and the pain point of the prior art is fundamentally solved. Disclosure of Invention (One) object of the invention: The invention aims to provide an automatic gluing pretreatment process and equipment for a lamp shell of a car lamp, which realize the automatic operation of the whole process of dust removal, flaming and gluing of the lamp shell and the automatic flow of materials by combining an industrial robot with an automatic line body, thoroughly cancel the manual participation of the whole process, solve the problems of high labor cost and high equipment manufacturin
