Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a wire gripper which is easy to connect with a robot arm. Background Art

[0002] The automatic wire threading machine uses machinery to replace manual labor to thread the product onto the wire. It requires the use of a robot arm 1 to transport the stacked racks 2 and to remove the wire from the rack 2.

[0035] Cylinder 14, each lower mounting seat 13 is mounted with a cylinder 14;

[0036] Upper grab block 15, which is mounted on the power output end of the cylinder 14;

[0037] The lower grab block 16 is arranged one above the other with the upper grab block 15 and the lower grab block 16 , and the lower grab block 16 is installed on the lower mounting seat 13 .

[0038] The working principle and beneficial effects of the above technical solution are:

[0039] The utility model discloses a wire gripper that is easy to connect to a robot arm. The tool tray of the quick-change tray 10 is used to achieve quick assembly and disassembly with the main tray of the quick-change tray 10 located at the end of the robot arm 1. The transfer gripper 3 can also be equipped with the tool tray of the quick-change tray 10. In this way, the transfer gripper 3 can also be easily and quickly connected to the robot arm 1. The utility model provides a wire gripper that is easy to connect to a robot arm. By providing the quick-change tray 10, the wire gripper and the robot arm 1 can be connected and disassembled, thereby achieving the purpose of easy connection.

[0040] In one embodiment, the model of the quick change tray 10 is AQC-6 automatic quick changer.

[0041] In one embodiment, the upper gripping block 15 is made of rubber.

[0042] In one embodiment, a proximity switch 17 is mounted on one of the lower mounting bases 13 .

[0043] In one embodiment, a hollow hole is formed at the end of the downlead mounting seat 13 near the lower gripping block 16 .

[0044] In one embodiment, the connector 12 includes:

[0045] The upper mounting shell 18 and the lower mounting shell 19 are both open at the bottom end of the upper mounting shell 18 and the bottom end of the lower mounting shell 19. The tool tray of the quick-change tray 10 is mounted on the top end of the lower mounting shell 19, and the upper mounting shell 18 is mounted on the top end of the lower mounting shell 19.

[0046] The fixing seat 20 is installed at the middle position of the top of the welding cross frame 11. The bottom end of the lower mounting shell 19 is clamped on the side end of the fixing seat 20. The side end of the fixing seat 20 is closed from bottom to top.

[0047] Bolt mounting seat 1 21, multiple bolt mounting seats 1 21 are integrally formed and mounted on the top of the upper mounting shell 18, and the hexagon socket bolts 28 are screwed from the bolt mounting seat 1 21 to the bottom end of the tool tray of the quick-change tray 10;

[0048] Bolt mounting seat 22, four bolt mounting seats 22 are integrally formed and installed on the top of the lower mounting shell 19, and the four corners of the bottom end of the upper mounting shell 18 are clamped on the top of the bolt mounting seat 22. The top of the upper mounting shell 18 is provided with a mounting hole 23, and the fixing bolt 24 is connected to the bolt mounting seat 22 from the mounting hole 23.

[0049] The working principle and beneficial effects of the above technical solution are:

[0050] The upper mounting shell 18 and the lower mounting shell 19 are provided with a cavity, thereby reducing the deadweight of the connecting seat 12. The bottom end of the tool tray of the quick-change disk 10 is reserved with a mounting screw hole. The tool tray of the quick-change disk 10 is placed on the upper mounting shell 18. After the mounting screw hole is aligned with the bolt mounting seat 1 21, the hexagonal bolt 28 is screwed into the bolt mounting seat 1 21, thereby completing the fixed connection between the tool tray of the quick-change disk 10 and the upper mounting shell 18. Then, the upper mounting shell 18 is placed on the lower mounting shell 19, and the fixing bolt 24 is screwed into the bolt mounting seat 2 2 from the mounting hole 23, thereby completing the fixed connection between the upper mounting shell 18 and the lower mounting shell 19. During this period, it is noted that the four corner positions of the bottom end of the upper mounting shell 18 are clamped at the top end of the bolt mounting seat 22, so as to facilitate quick finding of the installation position of the upper mounting shell 18 on the lower mounting shell 19. Finally, the fixing seat 20 is installed in the middle position of the top end of the welding cross frame 11.

[0051] In one embodiment, a limiting groove 25 is provided at the top center of the lower mounting shell 19 , and the inner wall of the limiting groove 25 is closed from top to bottom. A central fixing column 26 adapted to the limiting groove 25 is installed at the top of the upper mounting shell 18 .

[0052] The beneficial effects of the above technical solution are:

[0053] Before the four corner positions at the bottom end of the upper mounting shell 18 are clamped on the top end of the bolt mounting seat 22, the central fixing column 26 preferentially contacts the limiting groove 25 and is clamped in the limiting groove 25, thereby enabling the upper mounting shell 18 to quickly find the center position on the lower mounting shell 19.

[0054] In one embodiment, the center position of the bottom end of the fixing seat 20 is concave, and the center fixing bolt 27 is screwed into the limiting groove 25 from the bottom end of the fixing seat 20 .

[0055] The working principle and beneficial effects of the above technical solution are:

[0056] The central fixing bolt 27 is screwed into the limiting groove 25 from the bottom end of the fixing seat 20 , thereby completing the fixed connection of the lower mounting shell 19 on the fixing seat 20 .

[0057] In one embodiment, a side mounting plate for connecting with the top end of the welding cross frame 11 is installed opposite to the side end of the fixing seat 20 .

[0058] The beneficial effects of the above technical solution are:

[0059] A side mounting hole can be opened on the side mounting plate, and the side mounting hole can be penetrated by using fastening bolts to detachably install the side mounting plate and the fixing seat 20 connected to the side mounting plate on the welding cross frame 11, and the top of the welding cross frame 11 can also be reserved with a lower mounting screw hole adapted to the fastening bolt.

[0060] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
