The preferred embodiments of the dual valve air supply module of the present invention will be described with reference to the accompanying drawings.
Referring to fig. 1, 2 and 3, the dual valve gas supply module includes:
the air supply electromagnetic valve V1 is a two-position five-way electromagnetic valve, the air inlet end of the air source is communicated with an air source, preferably, the air supply pressure of the air source in the double-valve air supply module is 0.5-0.8 Mpa. The air supply solenoid valve V1 has its normally closed air outlet end communicated with the air inlet end of the locking actuator for locking the tool side and the robot side of the quick tool change device, and preferably, the locking actuator may be a pneumatic actuator, such as an air cylinder.
The control electromagnetic valve V2 is also a two-position five-way electromagnetic valve, the air inlet end of the air source is communicated with the normally open air outlet end of the air supply electromagnetic valve V1, the normally open air outlet end of the control electromagnetic valve V2 is communicated with the air outlet end of the locking execution piece, and the normally closed air outlet end of the control electromagnetic valve V2 is communicated with the normally open air outlet end of the air supply electromagnetic valve V1.
In this embodiment, the air supply solenoid valve V1 and the control solenoid valve V2 may be two-position five-way solenoid valves of the same type, and for one two-position five-way solenoid valve, the No. 1 interface is an air supply inlet end, the No. 2 interface is a normally closed inlet end, the No. 3 interface is a normally closed exhaust end, the No. 4 interface is a normally open inlet end, the No. 5 interface is a normally closed exhaust end, and the switch position 14 is a forced switch of the two-position five-way solenoid valve.
In this embodiment, the two-position five-way solenoid valve used in the double-valve air supply module is a single-coil solenoid valve, and the reset of the solenoid valve is mainly realized by an internal spring.
The valve seat 1 is provided with an air supply electromagnetic valve V1 and a control electromagnetic valve V2, namely, installation places of the air supply electromagnetic valve V1 and the control electromagnetic valve V2, and the valve seat 1 is installed on the tool side of the quick tool change device.
The protection shell 2 is arranged on the valve seat 1, an air supply electromagnetic valve V1 and a control electromagnetic valve V2 are installed in the protection shell 2, and the protection shell 2 is used for protecting the two most core electromagnetic valves of the double-valve air supply module.
Referring to fig. 3, the air supply solenoid valve V1 opens automatically after reaching the sensing area of the docking station (or other loading/unloading area), and the control valve V2 is controlled externally, and must be controlled externally only at the sensing area of the docking station.
In the embodiment, a locking loop pressure sensor B1 is connected in parallel to a pipeline through which the normally closed air outlet end of the air supply electromagnetic valve V1 communicates with the air inlet end of the locking actuating member, and the normally closed air outlet end of the air supply electromagnetic valve V1 communicates with the air outlet loop pressure sensor B2. The locking loop pressure sensor B1 can indirectly exhaust gas and feed back the valve core position of the air supply solenoid valve V1, and similarly, the exhaust loop pressure sensor B2 is provided to indirectly determine the valve core position of the control solenoid valve V2 when the valve core of the control solenoid valve V2 is stuck at a certain position.

Two-position five-way electromagnetic valves in the double-valve air supply module, wherein one electromagnetic valve is used as an air supply valve, the other electromagnetic valve is used as a control valve, only when an air supply electromagnetic valve V1 for air supply is firstly opened (automatically opened when the air supply electromagnetic valve reaches a parking station), then a control electromagnetic valve V2 for control is opened, the electromagnetic coil of the air supply electromagnetic valve V1 is electrified, the air supply air inlet end and the normally open air inlet end of the air supply electromagnetic valve V1 are communicated, so that an air supply function is realized, because the air supply air inlet end of the control electromagnetic valve V2 is communicated with the normally open air outlet end of the air supply electromagnetic valve V1, an air supply is used for supplying air to the control electromagnetic valve V2 through the air supply electromagnetic valve V1, and because the normally open air outlet end of the control electromagnetic valve V2 is communicated with the air outlet end of the locking execution piece, the normally open air outlet end of the control electromagnetic valve V2 becomes the air inlet end of the locking execution piece when the electromagnetic coil of the control electromagnetic valve V2 is electrified, and the normally closed air inlet end of the air supply electromagnetic valve V1 becomes the air outlet end of the locking execution piece, the output shaft of the locking executing part can retract, so that the tool side and the robot side are loosened, and the tool side is unlocked. It can be understood that when the two solenoid valves, i.e., the forced switches of the air supply solenoid valve V1 and the control solenoid valve V2, are manually pressed, the normally open air outlet end of the control solenoid valve V2 will become the air inlet end of the locking actuator, the normally closed air inlet end of the air supply solenoid valve V1 will become the air outlet end of the locking actuator, the output shaft of the locking actuator will also retract, and the tool side can also be unlocked.
In the double-valve air supply module, the air supply electromagnetic valve V1 is opened only at a fixed point position (a parking station), the air supply electromagnetic valve V1 is controlled by a detection element at the fixed point position and a connecting pipeline of two-position five-way single electric control valves which are pneumatically interconnected through double channels, and the double-valve air supply module is not controlled by the command of a robot so that the risk of manual operation does not exist. Further, when the tool side is to be forcibly unlocked manually, the two solenoid valves, i.e., the air supply solenoid valve V1 and the control solenoid valve V2, need to be simultaneously pressed.
As long as one of the electromagnetic valves is located at other positions, the No. 2 interface of at least one electromagnetic valve, namely the normally closed air inlet end, always admits air, the locking executing part lacks the air inlet end or the air outlet end, cannot retract, and the tool side and the robot side are always locked. Two solenoid valves all are in under the off-state, and the 2 # interface of two solenoid valves is that normally closed inlet end admits air all the time, and the end of giving vent to anger that normally opens of control solenoid valve V2 will become the end of giving vent to anger of locking executive, and the normally closed inlet end of air feed solenoid valve V1 can become the inlet end of locking executive, and the output shaft of locking executive can stretch, realizes that the instrument side locks with the robot side.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
