Description

Automatic Adhesive Supply Device for Bolts The present invention relates to an automatic adhesive supply device for bolts, and more specifically, to an automatic adhesive supply device for bolts capable of actively setting the bolting position for each workpiece through measurement of the workpiece. At the current level of technology, the method of setting bolting operations based on jigs is generally used. Jigs are tools used to fix the position of a workpiece or to enhance operational accuracy, playing an essential role in various manufacturing and assembly processes. In particular, for bolting operations, it is crucial to precisely adjust the position of the workpiece based on the jig and accurately set the fastening position and angle of the bolt. This enables the maintenance of operational consistency and quality, while also increasing operator convenience. However, at the current level of technology, various problems arise during the process of setting up bolting operations based on jigs. First, the jig setting process is often complex and time-consuming. When the size and shape of the workpiece vary, additional time is required to adjust and set the jig, which can lead to a decrease in productivity. Second, since jig setting often relies heavily on the operator's skill level, there is a possibility that the accuracy of the bolting operation may be compromised due to a lack of experience or errors. Furthermore, the method of setting bolting operations based on jigs has limitations in that it is difficult to flexibly respond to changes in the work environment or the diversity of workpieces. For example, if the size or shape of a workpiece changes, it may result in the inconvenience of having to modify existing jigs or manufacture new ones. This problem not only reduces the flexibility of the production process but can also lead to additional costs and time. Consequently, at the current level of technology, the method of setting bolting operations based on jigs has various constraints and limitations, and there is a growing need to improve it.
