A PLC includes a single-chip, a DC power module, a relay output module, an I/O module, and a pulse output module. The single chip includes a single-chip timer, a hardware watchdog, a 11.0592M crystal, and an A/D converter module. A system program is burned into an EEPROM (Electrically Erasable Programmable Read-Only Memory) of the single-chip. The system program includes a programming module and a control module. A DC power module includes an anti jamming circuit, a first output port, and a second output port. The first output port and the second output port are respectively connected to the anti-jamming circuit, and the single-chip is connected to the first output port. A relay output module is connected to the second output port. An I/O module receives and sends digital signals.

Programmable logic controller

A PLC includes a single-chip, a relay output module, an I/O module, a pulse output module, a relay, and a servo motor. The single chip includes a single-chip timer, a hardware watchdog, a 11.0592M crystal, and an A/D converter module. A system program is burned into an EEPROM of the single-chip. The relay connected to the relay output module. The servo motor is connected to the pulse output module. The system program includes a programming module and a control module. The programming module includes a main function and a function subroutine library, and the main function calls the subroutines of the function subroutine library. The control module scans the input signals from the I/O module during predetermined period, and then generates output signals according to the control commands generated by the programming module, to control output of the relay output module and the pulse output module.

Programmable logic controller employing single-chip

A tool holder, used for holding a milling cutter and a grinding wheel, includes a tool bar, a tool base, a flange, a mounting shaft, and a fixing ring. The flange is formed on an end of the tool bar. The tool base is used for mounting the milling cutter. The ends of the mounting shaft are connected to the flange and the tool base respectively. The grinding wheel is mounted on the mounting shaft. The fixing ring is used for fixing the grinding wheel to the mounting shaft.

Tool holder

A robotic claw includes a sleeve, a rod, a plurality of balls and a plunger. The sleeve comprises a mounting portion and a clamping portion. A mounting hole defined at an end of the mounting portion. A plurality of receiving through holes defined in the clamping portion, and an assembling hole communicating with the receiving through hole, and is defined at an end of the clamping portion. The balls are movably received in the receiving through holes correspondingly. The rod comprises an urging portion movably received in the sleeve to push the balls toward the receiving through holes. The plunger seals the assembling hole to prevent the balls from dropping out of the receiving through holes, and the balls can be mounted in the receiving through holes through the assembling hole.

Robotic claw and robot using same

A method for reloading workpieces includes providing a manipulator having a connecting base and a plurality of grasping assemblies arranged on the connecting base, providing a plurality of original workpieces and a plurality of machined workpieces positioned in a plurality of machining positions, grasping the original workpieces by at least one grasping assembly, with at least one grasping assembly vacant, grasping one machined workpiece by one vacant grasping assembly, rotating the connecting base, so that one original workpiece is placed in one machining position by one grasping assembly, further rotating the connecting base until another vacant grasping assembly is opposite to another machining position, and repeating grasping the machined workpieces from the machining positions and placing the original workpieces on the machining positions until a last original workpiece is placed on one machining position. The manipulator used in the present method for reloading workpieces is also provided.

Method for reloading workpiece

An exemplary holding structure used for holding an object that defines a latching hole, includes a main body, a pressing member received in the main body, and two latching members. The main body includes a lodging portion for being lodged into the latching hole of object and two receiving holes are defined in the lodging portion. The latching members are received in the receiving holes. The pressing member is configured to press the latching members to partially extend out of the at least two receiving holes for holding the object. The pressing member is capable of disengaging from the at least two latching members for releasing the object from the lodging portion.

Holding structure for robotic arm

An exemplary manipulator includes a main body, a plurality of holding devices, and a supporting arm. The main body includes four connecting surfaces. The holding devices are connected to the connecting surfaces of the main body. The holding devices are configured to seize and release grasping members. Each of the grasping members defines four latching holes. The holding devices are capable of abutting inner surfaces of the latching holes. The supporting arm is fixed to the main body, and configured to rotate with the main body.
