[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Depend on Figure 1 to Figure 2 Provided is a special suction nozzle for suction and mounting of LED lens components, comprising a main body 1 and a suction nozzle body 2.

[0022] The body 1 and the nozzle body 2 are made of stainless steel, which is easy to process, rust-free, wear-resistant, and has a surface that is not easily scratched.

[0023] The main body 1 is installed on the suction device of the placement machine, and the suction nozzle main body 2 is installed at the bottom of the main body 1, and the suction nozzle main body 2 adsorbs the LED lens element.

[0024] The main body 1 and the nozzle body 2 are designed separately to facilitate replacement when damaged. At the same time, the main body 1 and the nozzle body 2 can also be integrally formed to increase air toughness.

[0025] Beneficial effects obtained by the main body 1 and the nozzle body 2: This nozzle is a special nozzle suitable for automatic suction and placement of special components. Compared with existing placement nozzles, the automatic placement quality is more stable, the imaging effect is better, and the operation efficiency is higher.

[0026] Depend on Figures 2 to 3 It is shown that the main body 1 includes a vacuum pipe 11 , two U-shaped grooves 12 , an annular groove 13 and an annular limiting block 14 .

[0027] The vacuum pipe 11 is arranged inside the main body 1 , and chamfers are provided on both sides of the top of the vacuum pipe 11 , so that the pipe of the suction device of the placement machine can be inserted into the vacuum pipe 11 for easy insertion.

[0028] A rubber pad is installed inside the vacuum pipe 11 to increase the sealing performance and avoid air leakage. At the same time, it prevents the vacuum pipe 11 from generating friction and wear with the suction equipment of the placement machine, thereby reducing the air tightness.

[0029] Two U-shaped grooves 12 are arranged on both sides of the top of the main body 1 and are symmetrically arranged. Corresponding blocks corresponding to the two U-shaped grooves 12 are arranged on the placement machine suction device. When the main body 1 is installed on the placement machine suction device, the corresponding blocks are installed in the U-shaped grooves 12 for positioning. At the same time, it is convenient for the main body 1 to be installed and docked with the placement machine suction device.

[0030] Chamfers are provided at the notches on both sides of the top of the U-shaped groove 12 to reduce burrs and facilitate the insertion of the corresponding block into the U-shaped groove 12 .

[0031] The annular groove 13 is opened on one side of the main body 1, the annular limit block 14 is arranged in the middle of the main body 1, chamfers are arranged on both sides of the annular groove 13, and inclined surfaces are arranged on both sides of the top of the main body 1. The two inclined surfaces are in an eight-shaped shape, which is convenient for insertion into the suction device of the placement machine.

[0032] The annular slot 13 is used to be stuck in the suction device of the placement machine to facilitate clamping and fixing; the annular limit block 14 is used to limit the insertion of the suction device of the placement machine to avoid the insertion depth being too long.

[0033] One end of the placement machine suction device is connected to a vacuum pump, which performs vacuuming.

[0034] Depend on Figures 1 to 3 It is shown that the nozzle body 2 includes a connecting sleeve 21 , a suction cup 22 and a suction hole 23 .

[0035] The connecting sleeve 21 is installed at the bottom end of the main body 1, the suction cup 22 is arranged at the bottom of the connecting sleeve 21, the adsorption hole 23 is arranged inside the suction cup 22, the adsorption hole 23 is communicated with the vacuum pipe 11, and the diameter of the adsorption hole 23 is smaller than the diameter of the vacuum pipe 11, thereby improving the adsorption effect of the adsorption hole 23.

[0036] The vacuum pump evacuates the adsorption hole 23 through the vacuum pipe 11 , and the suction cup 22 abuts against the surface of the LED lens element, thereby adsorbing the LED lens element to the suction cup 22 .

[0037] The diameter of the upper part of the vacuum pipe 11 is larger than that of the lower part. The diameter of the lower part of the vacuum pipe 11 is the same as the diameter of the adsorption hole 23. The upper part of the vacuum pipe 11 is used to install the adsorption end of the placement machine suction device, and the other end of the adsorption end of the placement machine suction device is installed on the vacuum pump.

[0038] The diameter of the top of the suction cup 22 is smaller than the diameter of the bottom. The suction cup 22 is in a trumpet-shaped shape. The suction hole 23 to the bottom of the suction cup 22 is in a trumpet-shaped shape. The trumpet-shaped shape can improve the uniformity of the suction of the suction cup 22.

[0039] When the utility model is used, the chip mounter suction device moves with the body 1 to the top of the LED lens element, so that the suction cup 22 is attached to the surface of the LED lens element, and the vacuum pump is started. The vacuum pump evacuates the adsorption hole 23 through the vacuum pipe 11, so that the suction cup 22 and the LED lens element are adsorbed together.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
