Description

Fastening device

The present invention relates to a fastening device, and in particular to a fastening device for locking or removing a screw.

In the car body assembly engineering of automobile manufacturing, screw locks are widely used to combine components and the vehicle body. At present, the operator usually holds the lock screw tool and pays the screw lock to the predetermined lock. However, when the lock is located under the vehicle body or at the corner of the line of sight, the operator needs to operate the inaccessible lock, such as underarm or lying down, or even touch the lock. Therefore, for the operation of the chassis of the vehicle body, the vehicle body is generally hoisted to facilitate the operation of the operator under the vehicle body, as shown in FIG. 1 , which is a schematic diagram of a conventional operator operating the lock screw tool 20 ′. The person needs to look up and raise the arm to operate the lock screw tool 20', however, this will face the problem of too high elevation angle and difficulty in operation. Whether it is underarm or looking up, it will cause a burden on the operator, which is not conducive to long-term operation.

In addition, in the manufacturing process, the vehicle body may not be lifted due to the operation flow, for example, the screw lock operation of the bumper. Automobile assembly engineering In the middle of the manufacturing process, the bumper work is usually at the end of the manufacturing process. At this time, the car body has been loaded with the tire to land, and the screw lock under the bumper is performed. Nowadays, when the operator performs the screw lock under the bumper, it is necessary to first confirm the screw hole with the hand touch, and then lock the screw, which causes time-consuming operation. In addition, it may also cause poor screw lock quality, such as skewed or un-locked screws, or even cause the screws to fall during the operation and fall into the gap of the car conveyor belt, which may cause dangerous problems.

Therefore, there is a need for an easy-to-operate fastening device that improves the quality of work and reduces work time.

In view of the above problems, the present invention provides a fastening device including a base, a fastening machine, an image pickup element, and a display. The fastening machine is disposed on one side of the base and moves relative to the base. The fastening machine has a fastening head. The imaging element is close to the fastening head and is interlocked with the fastening machine. The display is disposed on the base to display an image captured by the imaging element. The imaging element captures an operation target of the fastening machine and at least a part of the fastening head.

The fastening device of the present invention enables the operator to change the operational object from the tactile confirmation to the visual confirmation by setting the imaging element, and the alignment is easier and more precise. In addition, the locking screw tool is placed on the fastening device so that the operator does not need to bear the weight of the locking screw tool, so that the working time can be greatly reduced and the work quality can be effectively improved.

The above description of the present content and the description of the following embodiments are used to demonstrate and explain the present creation, and to provide a patent application form for the present creation. A further explanation.
