Mechanical claw protecting device

Abstract

The invention provides a mechanical claw protecting device. The mechanical claw protecting device comprises a mounting rack and a spline sleeve rotatingly arranged on the mounting rack, wherein the spline sleeve is provided with a spline shaft in a sleeve mode, the upper end of the spline shaft is provided with a linkage unit, the mounting rack is provided with a guide bar which is provided with aspring in a sleeve mode, the linkage unit is provided with a through hole, the guide bar penetrates through the through hole, and both ends of the spring abut against the mounting rack and the linkage unit respectively. When a pneumatic supply lacks pressure or is abruptly interrupted, the linkage unit can move upwards under the action of the spring, the spline shaft and a mechanical arm can moveupwards synchronously, the lower end of the mechanical arm can move away from a PCB (printed circuit board0 or a worktable, so that even when the PCB or the worktable moves horizontally, accidental collision between the lower end of the mechanical arm and the PCB or the worktable can be avoided, equipment damage caused by insufficient pneumatic pressure or abrupt interruption of the pneumatic supply to inserting equipment can be greatly reduced, and further the safety protecting function of the mechanical claw protecting device can be achieved.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to the field of mechanical claw protection devices. Background technique [0002] With the rapid development of the electronics industry, the application of electronic processing equipment is becoming more and more extensive, and the manipulator is a very commonly used device in electronic processing equipment. Electronic processing equipment is mainly used to pick up electronic components, and transport and install them to PCB circuits. board, but the existing electronic processing equipment has a relatively high cost of processing equipment due to its complex structure and high difficulty in control. [0003] In order to reduce the production and processing costs of the equipment, the manipulator of the existing electronic component insertion machine is generally driven by air pressure, and the up and down movement of the manipulator is realized by using the air pressure to d...

Problems solved by technology

However, in the actual production process, since the movement of the worktable of the plug-in machine in the horizontal direction is mainly controlled by the servo motor, and the movement of the manipulator in the vertical direction is controlled by the air pressure source, the control of the two is not related. When the air pressure When the air pressure of the source is insufficient or the air is suddenly cut off, the manipulator of the plug-in machine will fall under the action of its own gravity, and the lower end of the manipulator is very close to the PCB circuit board or the workbench. If the servo motor is still working at this time, the PCB circuit board and the workbench are horizontal When moving, the lower end of the manipulator is likely to collide with the PCB circuit board or the work, which is likely to cause damage to the PCB circuit board or the lower end of the manipulator, and even cause the lower end of the manipulator or the workbench to be scrapped, seriously affecting the normal production of the plug-in machine
