Such electronic components appeared as early as 1962. In the early days, it was only able to emit low-intensity red light. Later, other versions of monochromatic light were developed. So far, the emitted light has spread over visible, infrared and ultraviolet rays, and the luminosity has been improved to some extent. With the development of science and technology, LEDs are widely used in the fields of display and illumination.

The dispensing is one of the most important steps in the manufacturing process of the LED, and during the use process, air permeates into the liquid due to the excessive fluid pressure and the short valve opening time, so that air bubbles in the fluid are formed, and meanwhile, the nozzle is blocked due to the instant solidification of the dispensing, but the equipment continuously works, which causes material waste and is not beneficial to energy conservation and environmental protection.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, a dispensing device for an LED lamp capable of avoiding bubbles and blockage includes a housing 1, a nozzle 2 fixedly connected to a bottom end of the housing 1, a material conveying port 3 fixedly connected to a side end of the housing 1, an air inlet 4 fixedly connected to a side end of the housing 1, a sealing spring 5 fixedly connected to both ends of an interior of the housing 1, a sealing ring 6 fixedly connected to the sealing spring 5, a chute 7 fixedly connected to an inner side of a top of the housing 1, a movable block 8 movably connected to an interior cavity of the housing 1, a movable groove 9 formed in the movable block 8, a slide bar 10 movably connected to an interior of the chute 7, a fixed block 11 fixedly connected to a side end of the slide bar 10, a core shaft 12 rotatably connected to a side end of the fixed block 11, a shift lever 13 fixedly connected to an outer ring of the core shaft 12, a limit groove 14, a rotating rod 16 is movably connected in the groove of the movable groove 9, a linkage rod 17 is fixedly connected at the outer end of the rotating rod 16, a spring shaft 18 is fixedly connected at the outer ring of the mandrel 12, a dispensing head 19 is fixedly connected at the bottom end of the sliding rod 10, and a thimble 20 is fixedly connected at the side end of the dispensing head 19.

Wherein: one side of the shift lever deflector rod 13 close to the movable block 8 is a circular arc, and the other side is a right angle. The design can limit the unidirectional rotation of the motor, and effectively prevent the motor from moving repeatedly between the anticlockwise direction and the clockwise direction after being damaged

Wherein: the movable groove 9 is formed by combining a strip-shaped groove and a circular groove.

Wherein: the linkage rod 17 is fixedly connected to the output end of the external motor at the end far away from the rotating rod 16. The whole equipment structure is powered by an external motor and is driven to operate by a linkage rod 17.

Wherein: the glue dispensing head 19 needle head is a conical inclined needle head, and the needle point position of the needle head is lower than the needle point of the thimble 20. During the movement of the dispensing head 19, the needle 20 will contact the glue before it and clean the glue.

Wherein: the sealing spring 5 is arranged at two sides of the dispensing head 19 at the inner side of the shell 1.

Wherein: the fixed block 11 is positioned at one side of the sliding rod 10 far away from the sliding chute 7, and the movable block 8 is positioned at one side of the sliding rod 10 far away from the sliding chute 7.

Wherein: the limiting block 15 of the fixing block 11 is movably clamped in the limiting groove 14.

The working principle is as follows: when the motor is started to operate, the linkage rod 17 drives the rotating rod 16 to do anticlockwise circular motion in the movable groove 9. The rotating lever 16 slides rightward from the arc-shaped groove of the movable groove 9. When sliding onto toggle 13, toggle 13 rotates counterclockwise under force. At this time, the bottom of the limiting groove 14 rotates to the limiting block 15 along with the shift lever 13, the shift lever 13 does not rotate any more, then the rotating lever 16 slides into the movable groove 9 in the rectangular groove on the right side, at this time, the shift lever 13 loses the transmission force of the rotating lever 16, and the spring shaft 18 returns the shift lever 13 to its original position because the rotating lever 16 makes a circular motion, enters the rectangular groove, and then leans against the top of the groove. Under the action of the force, the dispensing head 19 connected with the movable block 8 and the slide rod 10 moves upwards, the rotating rod 16 continues circular motion and slides to the arc groove from the strip groove, and the rotating rod 16 slides leftwards in the movable groove 9. When slid into position with toggle 13, toggle 13 rotates clockwise under force. At this time, the bottom of the limiting groove 14 rotates to the position of the limiting block 15 along with the shift lever 13, and the shift lever 13 does not rotate any more. The swivelling levers 16 then slide into the strip-shaped groove on the right side of the active groove 9. At this time, the lever 13 loses the force of the rotating rod 16, the spring shaft 18 returns the lever 13 to the original position, and the rotating rod 16 enters the strip-shaped groove and then collides with the groove top. Under this force, the dispensing head 19 connected to the slide bar 10 and the movable block 8 moves downward. The bottom of the dispensing head 19, which moves downwards, carries the product from the delivery opening 3 into the interior of the housing 1 and through the spout 2. Meanwhile, the thimble 20 at the bottom of the dispensing head 19 moves downwards when meeting the inner wall of the trapezoid nozzle 2, and the thimble 20 rotates and gathers inwards under the action of force. When passing through the nozzle 2, the glue block is ejected, so that the glue dispensing head 19 dispenses glue normally.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
