They operate in conjunction with each other. In this work arrangement, after each production cycle, the point 30 The copper surface on the underside, which forms the basis of the source, has a certain amount of burrs and surface marks. Surface deposits can form. If these surface deposits are not removed, subsequent problems may arise. During spot welding, unwanted holes can form on the door. and this situation can directly negatively affect product quality. Sanding system (1), word The issue is to remove surface deposits without stopping the production line, in the relevant area 35 It is operated in a way that allows for automatic sanding. 9 At the start of operation, the sanding system (1) has a safe waiting area within the production line. It is held in the parking position that forms the location. In this parking position, the carrier (10) The upper support arm (11) will remain stationary and will not occupy the working area and will be within the line. It is waiting in an angular position that will not interfere with other operating systems. Specifically, the same Due to the operation of 6-axis robots in the production area, the parking position system has a 5-axis capability. ensuring security and keeping the work area clear when not in use Thus, the sanding system (1) only activates when needed. and apart from that, a structure that remains in a passive waiting position within the line. It displays. With the emergence of the need for sanding, the system is structured in a possible way. mechanical switch, or in another possible configuration, another automation on the line. It is activated by a trigger signal received from the element. In the preferred configuration, production The sanding area as another robot operating on the line moves away from the relevant area.

Accordingly, sandpaper (20), 15 during angular movement with the connection region (12) as the center. It performs a circular scanning motion. Thus, the sanding process is carried out in a single, fixed motion. It can be applied in a controlled manner over a specific area instead of a single point. After the sanding process is completed, the motor (30) reverses the upper carrier arm (11). It rotates the system away from the working area by turning it in one direction. This return movement is 20 During this time, the upper carrier arm (11) exits the working area and returns to the parking position. is taken. In a possible configuration, during this return, sandpaper (20) is taken. or helps to remove sawdust and similar debris that has accumulated around it. is provided. With the return to the parking position, the sanding system (1) is ready for the next production. It enters a waiting state until the cycle and other automation on the line 25 This frees up the working area of ​​the elements. Thus, the operator can stop the line and enter. Without the need for any intervention, the sanding process is completed automatically. Production cycle time is maintained, and quality and efficiency are combined in the back door production line. It is being improved. During the sanding process, the air blower (23) is directed toward the sandpaper (20). By creating airflow, it removes dust, chips, and burr particles that are generated during the process. It removes particles from the working area.
