[0023] Implementation Method 1 Reference Figures 1 to 4 This embodiment, as an optional implementation of this application, discloses an anti-collision system for an automatic drilling and riveting equipment, including a laser scanning module 1 and a laser light curtain generating module 2. The laser scanning module 1 includes a plurality of laser scanners, each equipped with a first mounting base; the first mounting base is used to connect to the C-axis of the drilling and riveting equipment. The first mounting base includes a fixing base 101, which includes a U-shaped clip 1011. A fastening pad 1012 is provided on one side of the notch of the U-shaped clip 1011, and the fastening pad 1012 is also provided with a plurality of anti-slip teeth. A top support rod 1013 is threadedly connected to the other side of the notch of the U-shaped clip 1011. The top support rod 1013 is positioned opposite the fastening pad 1012. At the same time, an anti-slip suction cup 1014 is provided at the end of the top support rod 1013 that is opposite the fastening pad 1012.

[0024] The first mounting base of the above structure is adapted to the C-axis of the automatic drilling and riveting equipment. When in use, the top support rod 1013 is returned to the maximum position, thereby opening the opening end of the U-shaped clip 1011. After the clip is engaged, the anti-slip suction cup 1014 is tightly attached to the side of the C-axis by rotating the top support rod 1013, and then clamped on the C-axis. A support rod 1015 is also provided on the bottom surface of the U-shaped clip 1011. The threaded connection of the support rod 1015 is a limiting rod 1016, which abuts against the C-axis. The cooperation between the support rod 1015 and the limiting rod 1016 can provide anti-rotation support for the entire U-shaped clip 1011, thereby ensuring that the U-shaped clip 1011 can be stably clipped onto the C-axis and preventing it from rotating and shifting under its own weight.

[0025] Furthermore, a connecting rod 104 is also provided on the U-shaped card 1011, a rotating disk 105 is provided on the connecting rod 104, an adjustment hole 106 is provided on the rotating disk 105, and an adjustment ball 107 adapted to the adjustment hole 106 is provided on the first adjustment rod 102; a limiting disk 108 connected to the rotating disk 105 is also provided on the first adjustment rod 102. The first adjusting rod 102 and the connecting rod 104 are rotatably connected by adjusting ball 107 and adjusting hole 106, thereby maximizing the adjustment range of the first adjusting rod 102 and further enhancing the flexibility of the equipment; the first adjusting rod 102 is preferably a telescopic rod.

[0026] The free end of the first adjusting rod 102 is hinged to a base 103 that cooperates with the laser scanner. An adjusting seat 109 coaxial with the base 103 is also slidably disposed on the base 103. An adsorption magnet 110 for fixing the adjusting seat 109 to the C-axis is disposed on the adjusting seat 109. A fixing screw 111 for fixing the adjusting seat 109 is also threadedly connected to the base 103.

[0027] With the adjustment seat 109, the staff can adjust the height of the entire base 103 according to actual needs, and then cooperate with the first adjustment rod 102, which also has a telescopic adjustment function, to adjust the final installation point, thereby meeting different installation requirements and making equipment installation more flexible.

[0028] Compared with the prior art, this application enables the laser scanner to be stably installed at any point on the C-axis of the automatic drilling and riveting equipment as needed via the first mounting base.

[0029] The laser light curtain generation module 2 includes a first laser safety light curtain group 201, a second laser light curtain group 202, a third laser light curtain group 203, and a fourth laser safety light curtain group 204. The first laser safety light curtain group 201, the second laser light curtain group 202, the third laser light curtain group 203, and the fourth laser safety light curtain group 204 have the same structure and are all provided with connecting ear plates 205. The frame 3 is provided with connecting screws that are adapted to the connecting plate. The first laser light curtain group is used to mark the bottom surface of the enclosure 3 so as to form a laser light curtain at the bottom of the enclosure 3; The second laser light curtain group 202 is used to calibrate the side of the enclosure 3 facing the C-axis, thereby forming a laser light curtain on the side of the enclosure 3 facing the C-axis; the third laser light curtain group 203 and the fourth laser safety light curtain group 204 are used to calibrate the inner surface of the enclosure 3, and a laser light curtain for representing the inner surface of the enclosure 3 is formed by the above two laser light curtain groups. During use, the C-axis dimension boundary is calibrated by the laser scanning module to prevent collisions between external parts and the C-axis. The safety light curtain of the enclosure is calibrated by the laser light curtain generation module, that is, the bottom surface, side and inner surface of the enclosure are calibrated. The high-risk areas for collisions are directionally calibrated by the laser scanning module and the laser light curtain generation module, so that timely warnings can be given before a collision occurs and the machine can be stopped to ensure the safety of equipment operation. Secondly, this application eliminates the need for staff to simultaneously observe images from multiple cameras, which minimizes the workload of staff and allows them to focus more on the processing of parts, thus improving the processing quality of parts.
