[0020] See also Figure 1 , Figure 2 and Figure 6 The present invention provides a technical solution: a bracket system for quickly replacing robot end tools, comprising a base plate 7, a welding column 5 is fixed to the top of the base plate 7 by welding, and a mounting plate 8 is welded to the top of the welding column 5, the welding column 5 is welded and fixed to the top of the base plate 7, and the mounting plate 8 is welded to the top of the welding column 5, so that the bracket connection is firm and reliable.

[0021] The top of one side wall of the welding column 5 is fixedly connected to the flip cylinder 1 by screws, and the end of the flip cylinder 1 is fixedly installed with a dust cover 3 by screws, and the dust cover 3 is located above the welding column 5. The left locating pin 2 and the right locating pin 4 are symmetrically arranged in the mounting plate 8, and a detection sensor 11 is installed at one end of the bottom of the mounting plate 8.

[0022] It should be noted that the present invention can accurately locate the stored tools through the left-side locating pin 2 and the right-side locating pin 4, which is convenient for quick retrieval and placement. The detection sensor 11 can detect the presence of stored tools, and feed back the detection signal to the upper system to determine whether they can be grabbed or placed. The mounting plate 8 is fixedly connected to the top of the welding column 5 by welding, and the flip cylinder 1 is fixedly installed on the top of the rear part of the welding column 5 by screws. When replacing the equipment, the flip cylinder 1 can be controlled to control the dust cover 3 to move away from the fixing seat 14. After the equipment is replaced or installed, the dust cover 3 is connected to the top of the fixing seat 14 by the flip cylinder 1, so that the dust cover 3 can cover the quick-change disk of the equipment, effectively avoiding the influence of dust on the equipment.

[0023] See also Figure 3 and Figure 4 The bottom of the mounting plate 8 is located on the outside of the left positioning pin 2 and is connected to a No. 1 nut 9, and the bottom of the mounting plate 8 is located on the outside of the right positioning pin 4 and is connected to a No. 2 nut 10.

[0024] It should be noted that the mounting plate 8 is firmly fixed to the outer sides of the left locating pin 2 and the right locating pin 4 by means of the No. 1 nut 9 and the No. 2 nut 10, which further enhances the stability of the mounting plate 8 and the bracket structure. This connection method provides strong anti-vibration and anti-loosening performance, especially during the operation of the robot, preventing loosening caused by vibration or external force. The fixing effect of the No. 1 nut 9 and the No. 2 nut 10 ensures that the tool or accessory can always maintain a precise position, avoiding inaccurate operation or tool loss due to unstable connection.

[0025] See also Figure 1 and Figure 5 A connecting groove 17 is provided on the side of the mounting plate 8 away from the flip cylinder 1, and a fixing seat 14 is connected to the top of the mounting plate 8. Plug holes 15 are symmetrically provided on the top of the fixing seat 14. The left locating pin 2 and the right locating pin 4 are respectively clamped in the two plug holes 15, and a mounting groove is provided in the middle of the fixing seat 14.

[0026] It should be noted that the design of the left locating pin 2 and the right locating pin 4 enables the tool to be accurately docked on the bracket to avoid inaccurate placement or looseness of the tool. The left locating pin 2 and the right locating pin 4 provide good mechanical positioning to ensure that the tool can be quickly and securely installed and removed. The left locating pin 2 and the right locating pin 4 are respectively used in conjunction with the socket 15 in the mounting plate 8 to ensure that the tool is accurately aligned on the bracket, thereby improving the accuracy and efficiency of the operation. The left locating pin 2 and the right locating pin 4 can also facilitate users to quickly replace tools and reduce downtime.

The detection sensor 11 can detect the presence or absence of the grinding and polishing equipment 12, and feed back the detection signal to the upper system to determine whether it can be grasped or placed.

[0029] See also Figure 6 A detection device 13 is installed in the welding column 5 , and a detection device 13 is installed in the welding column 5 . The quick-change plate at the top of the detection device 13 is fixedly installed in the mounting groove of the mounting plate 8 .

[0030] It should be noted that the quick-change disk of the detection equipment 13 can be installed inside the mounting groove on the mounting plate 8, so that the detection equipment 13 is located in the connecting groove 17, and the bottom end of the detection equipment 13 is located in the welding column 5. The detection sensor 11 can detect the presence or absence of the equipment 13, and feed back the detection signal to the upper system to determine whether it can be grasped or placed. Through the grinding and polishing equipment 12 and the detection equipment 13, the system can not only complete the replacement of the tool, but also detect the status of the tool during the process and perform necessary processing.

[0031] See also Figure 1 Reinforcing ribs 6 are symmetrically arranged at both ends of the top of the flip cylinder 1, and the reinforcing ribs 6 at both ends of the bottom plate 7 are respectively connected to the corresponding two side walls of the welding column 5, and the reinforcing ribs 6 are respectively fixed to the bottom plate 7 and the welding column 5 by welding.

[0032] It should be noted that the welded columns 5, reinforcing ribs 6, bottom plates 7, and mounting plates 8 are welded together to form the base of the bracket.
