Problems solved by technology
[0004] However, at present, the valve that controls the negative pressure device will still have a small negative pressure on the suction nozzle after closing the air channel. If the connection between the LED patch and the bracket is not firm enough, you need to set the program. Reduce the moving speed of the suction nozzle at the installation position to avoid taking out the LED patch when the suction nozzle leaves, which will cause the installation process to slow down. If the speed is not slowed down, the installed LED patch will be taken out, resulting in poor quality

Embodiment Construction
[0044] The present invention will be further described below in conjunction with the accompanying drawings.
[0045] Such as Figures 1 to 7 The suction nozzle 1 of the shown LED high-speed placement machine head includes a tube body 10, the outer periphery of the tube body 10 is wrapped with a rubber tube 3, the tube wall 30 of the rubber tube 3 is provided with a plurality of ventilation holes 34, and the open end of the tube body 10 is Located in the middle of the rubber tube 3, the top of the rubber tube 3 is sealed and fixed on the outer peripheral side wall of the tube body 10, the ventilation holes 34 are uniformly arranged around the circumference of the rubber tube 3, and the bottom of the rubber tube 3 is provided with a negative pressure port 33 for absorbing LED patches , the inner side of the negative pressure port 33 is provided with a return spring 2, and the two ends of the return spring 2 are against the inner side of the negative pressure port 33 and the open...

The invention discloses a suction nozzle of an LED high-speed mounting head, including a tube, a rub tube is wrapped around that outer periphery of the tube, the rubber tube top end is sealed and fixed to the outer circumferential side wall of the tube body, a negative pressure port for sucking the LED patch is arranged at the bottom of the rubber tube, a return spring is arranged at the inside ofthe negative pressure port, and the negative pressure ports at the two ends of the return spring and the open ends of the tube body are arranged at the inside of the negative pressure port; By meansof the suction nozzle made by the method, as that suction nozzle mount the led patch on the bracket, at that same time, the rub tube is deformed, the vent hole on the surface of the rub tube is opened, and the vent holes are connected with the inside and outside of the rub tube, so that the negative pressure is released from the vent holes, the inner and outer air pressures are balanced, the situation that the pasted led patch is taken out is avoided, and the production efficiency and the speed are ensured.
Description
technical field [0001] The invention relates to a suction nozzle for LED patch, in particular to a suction nozzle of an LED high-speed patch machine head and a preparation method for the suction nozzle. Background technique [0002] The LED placement machine is a device used to take the LED patch and place it on the LED bracket. [0003] The current LED placement machine uses a rubber suction nozzle to pick up the LED patch through negative pressure suction. After reaching the position specified by the bracket, it stops generating negative pressure and embeds the LED patch on the bracket. The suction of the machine head The mouth continues to move to the stacking place of the LED patch, picks up a new LED patch, and then continues to install, so as to reciprocate. [0004] However, at present, the valve that controls the negative pressure device will still have a small negative pressure on the suction nozzle after closing the air channel. If the connection between the LED p...
