机器人涂装线的前处理如何做才能提高效率
涂装喷涂线的主要组成部分包括:前处理设备、粉末喷涂系统、喷涂设备、烘烤箱、热源系统、电控系统、悬挂输送链等。涂装线的前处理设备是在涂装前清除涂装表面的各种油污和灰尘,使涂装表面清洁的清除工序是涂装前处理过程中必不可少的。更少的工序,消除了被涂物的基材和表面状况,涂装工艺需要选择。
The main components of the painting and spraying line include pre-treatment equipment, powder spraying system, spraying equipment, oven, heat source system, electrical control system, suspension conveyor chain, etc. The pre-treatment equipment of the painting line is essential for removing various oil stains and dust from the painted surface before painting, and the cleaning process of the painted surface is indispensable in the pre-treatment process of painting. Fewer processes eliminate the substrate and surface condition of the coated material, and the coating process needs to be selected.
在建立涂装线前处理时,必须先完成工艺设计,然后才能进行非标设备的设计、制造和安装。因此,工艺设计是建立生产线的基础,正确合理的路线将对生产操作和产品质量产生良好的影响。
Before establishing the pre-treatment of the painting line, the process design must be completed first, and then the design, manufacturing, and installation of non-standard equipment can be carried out. Therefore, process design is the foundation for establishing a production line, and a correct and reasonable route will have a good impact on production operations and product quality.
前处理的具体分类:前处理是在涂装前清除工件表面的氧化皮、铁锈、油脂、灰尘等污垢,使涂装粉末与金属表面牢固结合的过程,附着力强,使产品获得高品质,延长产品使用寿命。
The specific classification of pre-treatment: pre-treatment is the process of removing oxide scale, rust, grease, dust and other dirt from the surface of the workpiece before painting, so that the coating powder can firmly bond with the metal surface, with strong adhesion, resulting in high-quality products and extending product service life.
脱脂----水洗----表面调整----贴膜----水洗(根据工件特性灵活调整)。前处理分为喷淋式、浸泡式、潜泳式三种形式。根据工件和具体的生产要求选择处理方法。目前喷涂设备管道的表面处理普遍采用喷淋式联合清洗机。清洗原理是利用喷雾机械力和化学作用完成脱脂、磷化、钝化、清洗等过程。
Degreasing - Water washing - Surface adjustment - Film coating - Water washing (flexible adjustment according to the characteristics of the workpiece). Pre treatment is divided into three forms: spraying, soaking, and diving. Select the processing method based on the workpiece and specific production requirements. At present, the surface treatment of spraying equipment pipelines generally adopts a spray type combined cleaning machine. The cleaning principle is to use spray mechanical force and chemical action to complete degreasing, phosphating, passivation, cleaning and other processes.
涂装设备流水线的七大组成部分主要包括:前处理设备、喷粉系统、喷漆设备、烘箱、热源系统、电控系统、悬挂输送链等。如脱脂、磷化、清洗、干燥、喷粉、固化。这是一个系统的、连贯的过程,是涂装设备流水线的基本生产特征。
The seven major components of the painting equipment assembly line mainly include: pre-treatment equipment, powder coating system, spray painting equipment, oven, heat source system, electrical control system, suspension conveyor chain, etc. Such as degreasing, phosphating, cleaning, drying, powder coating, and curing. This is a systematic and coherent process, which is the basic production characteristic of the painting equipment assembly line.
“那么有什么方法可以提高喷涂线的效率呢?”
So what methods are available to improve the efficiency of the spraying line
1.提高衣架的利用率
1. Improve the utilization rate of hangers
根据工件的大小和类型,我们可以选择全套吊具或单室吊具。如果工件不完整,有空闲吊点,我们将整套吊具改为单台吊具,以提高吊具的有效利用率。如果工件种类多,就需要使用两用挂架,这样一个挂架可以挂不同的工件,不用频繁更换挂架。
According to the size and type of the workpiece, we can choose a complete set of lifting equipment or a single room lifting equipment. If the workpiece is incomplete and there are available lifting points, we will replace the entire set of lifting equipment with a single lifting equipment to improve the effective utilization rate of the lifting equipment. If there are multiple types of workpieces, a dual-purpose hanger is needed, so that one hanger can hang different workpieces without frequent replacement.
2.增加备用油箱
2. Add a backup fuel tank
在生产旺季,涂装设备流水线也24小时不间断运行。由于产量的增加,脱脂罐和预脱脂罐中的罐液往往在几天内就需要更换,更换罐液也占用了正常生产时间的一部分。为了保证产品质量,不耽误正常生产时间,我们对线体进行了改造。在原有脱脂罐和预脱脂罐的基础上,并联了脱脂罐和预脱脂罐。无论何时更换浴液,都不会影响正常生产时间,只需提前准备另一种浴液即可。这也是提高喷涂线生产效率的有效途径。
During the peak production season, the painting equipment assembly line also operates 24 hours a day without interruption. Due to the increase in production, the tank solution in the degreasing tank and pre degreasing tank often needs to be replaced within a few days, and replacing the tank solution also takes up a part of the normal production time. In order to ensure product quality and not delay normal production time, we have made modifications to the production line. On the basis of the original degreasing tank and pre degreasing tank, degreasing tank and pre degreasing tank are connected in parallel. No matter when the bath is changed, it will not affect the normal production time, just prepare another type of bath in advance. This is also an effective way to improve the production efficiency of the spraying line.
3、精细化管理
3. Refined management
通过精细化管理,可以掌握各工序的实际产能,为合理组织生产和平衡产能提供基础数据支持,关注涂装工艺,细化各工序的操作步骤、工艺参数、操作规范等。每个过程。在工艺文件中,任何工人都可以按照工艺文件的规定生产出合格的产品。统筹协调整条涂装线的产能。
Through refined management, the actual production capacity of each process can be grasped, providing basic data support for rational organization of production and balancing production capacity. Attention should be paid to the coating process, and the operational steps, process parameters, and operating specifications of each process can be refined. Each process. In the process document, any worker can produce qualified products according to the regulations of the process document. Coordinate the production capacity of the entire painting line.
四、新漆前处理的使用
4、 The use of pre-treatment for new paint
在实际生产中,积极使用新型预处理剂,提高生产效率。过去,使用传统的油漆前处理剂,温度要求在50℃以上,每班生产前,都需要漫长的加热过程,尤其是在寒冷的冬季,有时达不到设定温度很长时间。后来又采用了新型低温磷化剂和脱脂剂,大大缩短了加热过程。方便生产管理,增加有效工作时间,从而提高生产效率。不仅如此,还能节约生产成本,实现多重目标。
In actual production, actively using new pretreatment agents to improve production efficiency. In the past, using traditional paint pre-treatment agents required a temperature of over 50 ℃, and a long heating process was required before each shift of production, especially in the cold winter when the set temperature could not be reached for a long time. Later, new low-temperature phosphating agents and degreasing agents were used, greatly shortening the heating process. Facilitating production management, increasing effective working time, and thus improving production efficiency. Not only that, but it can also save production costs and achieve multiple goals.
涂装设备、工作环境、涂装管理、涂装工艺和材料直接关系到喷涂线的生产效率。在这个过程中,涂装设备的工艺布置对喷涂线的使用有着重要的影响。因此,精益涂装的装配工艺也是有效提高其效率的重要因素之一。
The painting equipment, working environment, painting management, painting process, and materials are directly related to the production efficiency of the spraying line. In this process, the process layout of the painting equipment has a significant impact on the use of the spraying line. Therefore, the assembly process of lean coating is also an important factor in effectively improving its efficiency.
