[detailed description of the invention]
Principle such as Fig. 1 to Fig. 5 of this utility model embodiment electronic loader feeding trigger mechanism
Shown in, including frame 1, cylinder connecting rod 2, photoswitch 3, extension spring 5, backing pin 6 and touch
Power Generation Road, the signal output part of photoswitch 3 is connected with triggering circuit.
Photoswitch 3 and cylinder connecting rod 2 are arranged on the front portion of frame 1, cylinder connecting rod 2
For L-shaped structure, including the first arm 201 and the second arm 202 of corner connection, the end of the first arm 201
Portion is the connection end 201a of cylinder, and the end of the second arm 202 is described light barrier 202a；L
The position, turning of shape cylinder connecting rod 2 has a hinge hole hinged with frame 1 (not show in figure
Go out).
The hinge hole at the position, turning, middle part of cylinder connecting rod 2 is cut with scissors with frame 1 by jointed shaft 4
Connect.The jointed shaft 4 of L-shaped cylinder connecting rod is arranged in above photoswitch 3, the connection of cylinder
The light barrier 202a of end 201a and photoswitch is arranged in the lower section of jointed shaft.
Backing pin 6 is positioned at the outside of the second arm 202, and one end of extension spring 5 hangs over the second arm 202
Middle part, the other end hangs in frame 1.The active force of extension spring 5 makes the second arm 202 lean against backing pin
On 6, now, the light path during light barrier 202a blocks photoswitch 3.
Photoswitch 3 is flute profile photoswitch, including infrared transmitting tube 301 and infrared receiving tube
302。
Triggering circuit and include audion TR3, the positive pole of infrared transmitting tube meets positive source+5V,
Negative pole IR Feed passes through resistance R97 ground connection.Resistance R97 is for controlling the energy of infrared emission
Amount.
The positive pole of infrared receiving tube meets positive source+5V, negative pole PTR Feed and passes through resistance
R87 connects the base stage of audion TR3.Resistance R87 is for controlling the sensitivity received.
The grounded emitter of audion TR3, resistance R63 is connected on the emitter stage of audion TR3
And between base stage；Colelctor electrode meets positive source+5V by resistance R64.Audion TR3's
Colelctor electrode M FEED is the signal output part triggering circuit.
When the jacking block of chip mounter cylinder falls, the light barrier 202a of cylinder connecting rod blocks light
Light path in electric switch 3, infrared receiving tube is in cut-off state, and infrared through R87 connects
Receiving electric current the least, audion TR3 ends, and it is high level that feeding triggers signal M FEED
5V；When the jacking block jack-up of chip mounter cylinder, the light barrier 202a of cylinder connecting rod leaves light
Light path in electric switch 3, infrared receiving tube is in opening state, and infrared through R87 connects
Receiving electric current and enough open audion TR3, it is low level 0V that feeding triggers signal M FEED.
Audion TR3 uses radio frequency audion, can reach the purpose quickly responded.
This utility model above example improves the cylinder connecting rod structure of pneumatic type feeder,
Use cylinder connecting rod to coordinate infrared switch, mechanical movement is converted into photosignal, is transferred to
The controller of electronic feeder, thus realize the transmission of feeding order, it is simple to by electronic loader
It is applied on traditional chip mounter.
