What should be noted when making a suction nozzle rod?

The case in this article involves a nozzle rod.

With the improvement of people's living standards, digital cameras, video cameras and other devices are being used more and more widely, and the demand for lens components set inside them is also increasing accordingly. Optical lens assembly requires first adhering the lens to the lens holder to form a semi-finished product. Usually, the lens holder is placed in the dispensing fixture first, and the adhesive is applied to the lens holder. The surface mount machine uses a nozzle to adhere the lens to the lens holder, and the nozzle is installed on the surface mount machine through a nozzle rod. The traditional suction nozzle rod has a trapezoidal installation head for installing the suction nozzle. After installation, the suction nozzle is prone to fall off, which affects the production progress. In addition, the suction nozzle rod is integrally formed. When the suction nozzle rod is damaged due to improper human operation, it needs to be discarded as a whole, which is very wasteful.

This case study overcomes the shortcomings of the existing technology and provides a suction nozzle rod with a simple structure.

To achieve the above-mentioned purpose, the technical solution adopted in the case of this article is as follows: a suction nozzle rod, including a first rod body assembly and a second rod body assembly. The first rod body assembly comprises a first rod body, a first disc body, a second rod body and a second disc body fixed in sequence from top to bottom. The first rod body assembly is successively provided with a first through hole, a second through hole, a third through hole and a fourth through hole along the axial direction from top to bottom. The second rod body assembly includes a third rod body, a third disc body, a fourth rod body and a square installation head that are successively fixed from top to bottom. The second rod body assembly is provided with a vent hole along the axial direction. Part of the third rod body is inserted into the second through hole. The third disc body is inserted into the third through hole.

• The suction nozzle rod further includes a ring-shaped groove provided on the first rod body.
• The suction nozzle rod further includes that the diameters of the first through hole, the second through hole, the third through hole and the fourth through hole increase in sequence.
• The suction nozzle rod further includes that the vent hole is a step hole.
• The suction nozzle rod further comprises the first rod body, the first disc body, the second rod body, the second disc body, the third rod body, and the third disc body and the fourth rod body, all of which are circular.
• The suction nozzle rod further comprises an arc transition between the adjacent sides of the square mounting head.
• The suction nozzle rod further comprises a free end of the first rod body in a conical shape.
• The suction nozzle rod further includes a cone Angle of 20-30 at the free end of the first rod body.

This case study resolves the deficiencies existing in the background technology. The structure of this case study is simple and easy to use. The suction nozzle can be stably attached to the square mounting head. The setting of the annular groove facilitates the positioning with the ball bearings, ensuring the positioning matching of the suction nozzle rod and helping to improve the positioning accuracy. The first rod body assembly and the second rod body assembly can be separated, facilitating the replacement of the first rod body assembly or the second rod body assembly. It does not need to be discarded as a whole, avoiding waste and reducing the production cost of enterprises. Meanwhile, after the lenses are bonded, the suction nozzle will not carry away the products, increasing the yield of dropped lenses by 5.6% and reducing the suction nozzle marks by 3.3%, ensuring product quality.
