Six-axis universal robot for material grabbing
ActiveCN106078725AImprove work efficiencyAccurate graspProgramme-controlled manipulatorEngineeringCam
The invention discloses a six-axis universal robot for material grabbing. The six-axis universal robot comprises a base body, a waist rotating component in pin joint to the base body, a large arm in pin joint to the waist rotating component and small arms mounted on the large arm. The waist rotating component rotates around the base body, and the large arm rotates around the waist rotating component. The two small arms comprise the first small arm and the second small arm. The two small arms are mounted on the large arm through a split mechanism. A mechanical hand assembly is arranged on the two small arms and comprises an arm, a swing arm in pin joint to the front end of the arm and a mechanical hand fixed to a rotating disc at the front end of the swing arm. The two small arms of the six-axis universal robot can rotate relative to the large arm through the split mechanism, the two small arms can oppositely rotate under drive of the split mechanism so as to adapt to various processing conditions, and the operation efficiency of the robot is improved. Grippers can be driven to move at the same time through gear transmission and cam combination and are the same in motion amplitude so that the mechanical grippers can grab workpieces accurately in an omnibearing manner.

A device for automatically removing the upper cover of a tuning fork crystal
The invention discloses a device for automatically taking an upper cover of a tuning fork crystal. The device comprises a cover-taking system rail and a cover-adding system rail, which are rotated in an inverted manner. An upper cover-taking mechanism is arranged at the outside of the cover-taking system rail. The upper cover-taking mechanism comprises a rack, a rack X-axis cam, a rack Z-axis cam, an upper cover cam, a cover-taking cam and a drive motor. The rack X-axis cam, the rack Z-axis cam, the cover-taking cam, the upper cover cam and the drive motor are connected with each other via a synchronous belt. Top rods are arranged at the tops of the cover-taking cam and the upper cover cam , and a cover-clamping device is arranged on the rack. Through the coordination of cam combination in a transmission mechanism and the cover-clamping device, the device of the invention could be used for precisely placing a crystal plate on a substrate in a perfect manner so as to free workers from high-intensitive work. The device of the invention is high in automatic level and greatly improves work efficiency.
