Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a robot end effector. Background Technology

[0002] A connector, also called a plug, is a component used to connect electronic devices. It typically consists of two parts: a plug and a socket. The plug is the movable part that inserts into the socket; the socket is the part that is fixed to the device. The purpose of a connector is to provide a pluggable connection method, facilitating the assembly, maintenance, and replacement of equipment. They can transmit signals and power between electronic devices, circuit boards, wiring harnesses, and other components.

[0003] Connectors are essential components in almost all electronic and electrical devices. Whether it is the assembly of electronic equipment or the testing of finished devices, the operation of connectors is involved, including actions such as clamping and transferring, plugging and unplugging, nesting, assembling, twisting, and turning.

[0004] When implementing automation in smart manufacturing, the diverse types and forms of connectors, based on their functions and specifications, make automation modifications difficult. Common approaches include: one is to use a robot or automated equipment to automate operations on only one or a few connectors with highly similar characteristics; another is to install a female quick-change device at the robot's end effector and arrange male quick-change devices around the worktable, changing the robot's end effector gripper when a specific connector needs to be operated. The second method can adapt to multiple connectors, but the types are extremely limited, usually only a single-digit number. Furthermore, it is costly, involves complex equipment, is difficult to debug, and has a high failure rate. Therefore, we propose a robot end effector gripper. Utility Model Content

The longitudinal groove gripper is inserted into the longitudinal groove, and the transverse groove gripper is inserted into the transverse groove.

[0008] A connector is detachably installed in the receiving slot, and the first clamping block, the second clamping block and the clamping driver are connected by a connecting component.

[0009] The connecting assembly includes: a threaded hole formed on the clamp driver; a mounting hole formed on the first clamping block and the second clamping block; a bolt passing through the mounting hole and threadedly connected to the threaded hole; and a reinforcing assembly disposed on the first clamping block and the second clamping block.

[0010] The bolt is an internal hexagonal type.

[0011] The reinforcing component includes: a hexagonal groove formed on the first clamping block and the second clamping block; a hexagonal block disposed in the hexagonal groove; and a limiting block installed in the hexagonal block and inserted into the hexagonal hole of the bolt.

[0012] The hexagonal block is connected to the first clamping block and the second clamping block by ropes.

[0013] The first clamping block and the second clamping block are provided with mounting grooves, and the mounting grooves are provided with elastic connectors. The bolts are provided with multiple positioning holes, and the free end of the elastic connectors is provided with positioning balls, which are inserted into the positioning holes.

[0014] The plurality of positioning holes are arranged at equal angles along the bolt axis on the bolt, and the hexagonal block and the hexagonal groove are attracted by magnetic force.
