Catching device for ultrasonic cleaning equipment

Abstract

The invention discloses a catching device for ultrasonic cleaning equipment. The catching device comprises a stander, a lifting arm arranged on the stander in a lifting manner, a lifting mechanism for driving the lifting arm to lift, a pair of catching hooks transversely and movably arranged on the lifting arm, and a control unit for controlling the lifting mechanism to run or stop, wherein sensors are arranged on the catching hooks respectively and comprise inductors which are arranged on the catching hooks in a lifting manner and at least partially positioned below the catching hooks, and triggers which are arranged on the catching hooks and triggered by the inductors; the triggers are in signal connection with the control unit; and the control unit receives alarm signals sent by the triggers and sends an instruction for controlling the lifting mechanism to run or stop. According to the catching device, when the lifting mechanism is out of work, the inductors below the catching hooks can upwards move under a small acting force and make the triggers send the signals, and the control unit brakes the lifting mechanism urgently; and therefore, a fixture is protected, and the phenomenon that the catching hooks fall down and damage the fixture is avoided.

Description

technical field [0001] The invention belongs to the field of ultrasonic cleaning equipment, and in particular relates to a grasping device for moving a tooling basket in the ultrasonic cleaning equipment. Background technique [0002] Solar silicon wafer automatic degumming machine is a kind of ultrasonic cleaning equipment, which belongs to the special equipment for solar silicon wafer pre-cleaning and degumming. The main production line of this equipment is: feeding, spray cleaning tank, ultrasonic cleaning tank, ultrasonic pickling The working principle of the degumming tank and blanking is to use the mechanical vibration with strong ultrasonic penetration to impact the surface of the workpiece and combine the chemical action of lactic acid to degumming the silicon wafer. [0003] Existing ultrasonic cleaning equipment usually uses a gantry mechanical arm to carry the tooling basket. The mechanical arm includes a translation trolley that can move laterally along the ultra...

AI Technical Summary

Problems solved by technology

In the event of interruption of production such as power failure or shutdown, there may be tooling that has not been taken out in time in the set process tank, but the control unit does not know that there are workpieces in the process tank, and the grapple is still lowered according to the set program. When the grapple The tooling grabbed by the upper part is blocked by foreign objects below and cannot be lowered. When the grapple continues to drop, the tooling will be crushed by the grapple.
