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. 1-5, an LED lamp dispensing device with adjustable single dispensing amount includes a back plate 1, a rotating wheel 2 fixedly connected to the surface of the back plate 1, and an output end of a motor or other devices connected to the center of the rotating wheel 2.

The surface of the rotating wheel 2 is provided with a sliding chute 3, the sliding chute 3 is an irregular ellipse, and the partial arc edge is closer to the center of the rotating wheel 2. The sliding groove 3 drives the sliding block I4 under the rotation of the rotating wheel 2, and the sliding groove 3 part closer to the circle center can drive the sliding block I4 to move up and down under the limitation of the clamping strip I5.

The sliding block I4 is movably clamped in the groove of the sliding groove 3, and the outer ring of the sliding block I4 is simultaneously sleeved on the inner ring of the sliding groove 3, the clamping strip I5 and the clamping strip II 8. The first slide block 4 is driven by the sliding groove 3 to drive the first holding strip 5 and the glue dispensing pipe 6 to move, and is limited by the position of the second holding strip 8.

The outer ring of the first sliding block 4 is movably sleeved with a first holding strip 5, the outside of the first holding strip 5 is movably sleeved with a dispensing tube 6, and the outside of the upper end and the lower end of the dispensing tube 6 are respectively tightly attached to the inner walls of the buffer cavity 62 and the dispensing head 7. The close relationship ensures that the dispensing tube 6 can convey the dispensing glue material in the process of moving up and down without leakage.

Through holes 61 are formed in two sides of the lower end of the dispensing tube 6, a buffer cavity 62 is movably connected to the upper end of the dispensing tube 6, a dispensing tube 63 is fixedly connected to the upper end of the buffer cavity 62, and dispensing glue is fed into the dispensing tube 63 downwards through the upper end at a constant speed.

The lower extreme of dispensing head 7 has been seted up out and has been glued hole 71, logical groove 72 has been seted up to the inside both sides of dispensing head 7, the centre of a circle department swivelling joint of runner 2 has holding strip two 8, the right-hand member fixedly connected with slider two 9 of holding strip two 8, the outer lane activity of slider two 9 has cup jointed the regulation and has pressed from both sides 10, the right-hand member fixedly connected with fixed strip 11 of regulation clamp 10, fixed strip 11's last well lower extreme fixed connection is in proper order simultaneously at cushion chamber 62, the outside right-hand member of regulation clamp 10 and dispensing head 7. The fixing strip 11 will synchronously fix the mutual position relationship of the buffer cavity 62, the adjusting clamp 10 and the glue dispensing head 7, ensuring that no relative displacement occurs between them.

The dispensing head 7 is movably sleeved at the lower end of the dispensing tube 6, and the lamp panel 12 is placed below the dispensing head 7. The lamp panel 12 is placed on the surface of the conveyor belt conveyed at a constant speed and moves from left to right at a constant speed, and the position and the interval are matched with the glue discharging rhythm of the glue dispensing head 7. When the lamp panel 12 moves to the position right below the dispensing head 7, the dispensing head 6 just releases dispensing material to the surface of the lamp panel 12.

The working principle is as follows: the rotating wheel 2 rotates under the power input of external motor equipment, the sliding groove 3 with the irregular surface drives the sliding block I4 to move and drives the clamping strip I5 to move, the sliding strip arranged inside the clamping strip I5 buffers the dislocation generated by the mutual movement between the two structures, and meanwhile, the clamping strip I5 drives the dispensing tube 6 to do up-and-down reciprocating motion under the limitation of the buffer cavity 62 and the dispensing head 7.

When the dispensing tube 6 is at the upper end of the up-and-down reciprocating motion in the non-dispensing interval, the through hole 61 formed at the lower end of the dispensing tube 6 is blocked by the inner wall of the dispensing head 7, and the dispensing material cannot pass through the dispensing tube 6; when the dispensing tube 6 is in the downward breaking of the up-and-down reciprocating motion in the dispensing interval, the lower end of the dispensing tube 6 is opened and moves to the lower part of the inner wall of the dispensing head 7 and is flush with the through groove 72, dispensing materials are not blocked any more, flow to the dispensing hole 71 from the lower end of the dispensing tube 6 through the through groove 72, and finally are dispensed on the surface of the lamp panel 12. Thus, one dispensing cycle is completed.

And adjusting the position of the second sliding block 9 in the adjusting clamp 10. If the second sliding block 9 moves along the adjusting clamp 10 from bottom to top, the first sliding block 4 is limited by the up-and-down movement of the second clamping strip 8 to be smaller, namely, the up-and-down movement amplitude of the first sliding block 4 is increased from small to large, and meanwhile, the amplitude of the up-and-down reciprocating movement of the dispensing tube 6 is driven to be increased. Meanwhile, as the lowest position of the dispensing tube 6 in motion becomes lower, when the dispensing tube 6 is at the lowest position, the contact surface between the through hole 61 and the through groove 72 is increased, and the dispensing amount per output is increased on the premise that the flow rate of the dispensing material is not changed and the rotation speed of the rotating wheel 2 is not changed. On the contrary, the second sliding block 9 is adjusted from top to bottom, the up-and-down movement amplitude of the sliding block is reduced, the lowest position of the movement of the driven dispensing tube 6 is increased, the contact surface between the through hole 61 and the through groove 72 is reduced, and the dispensing amount of single output is reduced. In the using process, the position of the second sliding block 9 on the adjusting clamp 10 is freely adjusted according to different requirements, so that the effect of adjusting the single dispensing amount can be achieved.

In conclusion, the LED lamp dispensing equipment with the adjustable single dispensing amount has the advantages that the rotating wheel 2, the sliding groove 3, the sliding block I4, the clamping strip I5, the dispensing pipe 7, the through hole 61, the buffering cavity 62, the rubber conveying pipe 63, the dispensing head 7, the glue outlet hole 71 and the through groove 72 are matched for use, the dispensing automation is achieved for the finished product, the precision is high, the dispensing is uniform, the manpower is released, the dispensing efficiency is improved, and the quality of the finished products such as the LEDs is finally improved. Through the cooperation use of slider one 4, holding strip two 8, slider two 9, regulation clamp 10 and fixed strip 11 to reach the effect that the volume is adjustable is glued to the single point, can deal with the demand that different single point glued volume products, improved the application scope to different conditions, compared and have certain practicality in prior art.

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.
