Tweezers for clamping miniature lens

Technical Field

With the rapid development of optical communication technology and the vigorous growth of optical communication manufacturing industry, as a ring of the optical module, the market requirement of the micro-miniature lens is also higher and higher, and the requirements of the appearance quality and antistatic performance of the lens are mainly improved.

In the batch processing process of the miniature lenses, the requirements on fixture clamps (such as tweezers for clamping the miniature lenses) are also higher and higher, so that the antistatic performance of the fixture and the adaptability of the fixture are required to be further optimized.

In the industrial production of miniature lenses at present, metal tweezers are used for clamping optical lenses with diameters of 4.0mm, 1.8mm, 1.0mm and even smaller, which are greatly required by the optical communication market. The disadvantage of using metal tweezers to grip a miniature optical lens is at least the following:

1. the metal tweezers are generally made of stainless steel, and compared with the special optical glass material of the optical lens, the stainless steel is obviously too hard, and the lens is easily damaged in the contact process of the stainless steel and the optical lens. Especially, the appearance quality of the light-passing surface of the optical lens is extremely severely required, and slight touch of the metal tweezers can introduce appearance flaws, so that products are scrapped. 2. Microminiature optical lenses generally generate static electricity during the manufacturing process. Because stainless steel metal tweezers are not antistatic, the lens is often adsorbed on the tweezers clamping opening, and the tweezers are inconvenient to clamp. 3. The weight of the existing metal tweezers is 10-20g, the length is 11-22cm, the operation is heavy, and the efficiency is low.

Detailed Description

Specific embodiments of the present utility model will be described in detail below with reference to fig. 1-2, but it should be understood that the scope of the present utility model is not limited by the specific embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-2, the tweezers for clamping the miniature lens are made of bamboo, and the tweezers are made of bamboo, so that the tweezers have the advantages of being strong in toughness, weaker in hardness than glass, static-free and the like. The pair of tweezers specifically comprises a tweezers handle 1, an upper tweezers arm 2, a lower tweezers arm 3 and a tweezers head 4, wherein the upper tweezers arm 2, the lower tweezers arm 3 and the tweezers handle 1 are of an integrated structure, so that a better clamping effect can be realized; grooves 5 are formed in two opposite side walls of the forceps head 4, the size of the grooves 5 on the forceps head 4 is matched with the diameter of the lens to be clamped, clamping of lenses with the diameters of phi 4.0mm and below is achieved, and the high-efficiency clamping requirement on products is achieved.

Preferably, the upper and lower tweezer arms 2, 3 taper in width at a distance of 2/3 of the length from the tweezer handle 1.

Preferably, the sides and corners of the upper tweezer arm 2 and the lower tweezer arm 3 are rounded.

Preferably, the outer arms of the upper tweezer arm 2 and the lower tweezer arm 3 are provided with anti-slip structures.

Preferably, the length of the forceps handle is 5-15mm.

Preferably, the length of the upper tweezer arm 2 and the lower tweezer arm 3 is 45-55mm, the width of the upper tweezer arm 2 and the lower tweezer arm 3 is 4-5mm at the position 2/3 away from the tweezer handle 1, and the width of the tweezer head 4 gradually narrows from the position to the direction of the tweezer head 4, and the width of the tweezer head 4 is 1.0-1.5mm.

Preferably, the spacing between the upper surface of the upper tweezer arm 2 and the lower surface of the lower tweezer arm 3 is 5-7mm.

Preferably, the forceps have an overall length of 50-70mm.

More preferably, bamboo with a bamboo joint diameter of about 7mm, smooth bamboo poles and a length of about 65mm is selected as the base material. The selected bamboo joints are used as forceps handles 1 of the forceps, and the length of the forceps handles 1 is about 10mm so as to better increase the strength of the forceps handles. The bamboo joint rear end is polished slick and sly, increases personnel's operation comfort level.

Grooves with the depth of 1-2mm are designed on the opposite sides of the bamboo poles along the diameter direction at the lower ends of the forceps handles, and then the grooves on the two pairs of sides of the bamboo poles are ground along the length direction until the bottoms of the grooves are exposed. Only two remaining pairs of sides with the width of 4-5mm of the bamboo poles are left to be used as forceps arms, and the lengths of the forceps arms are 45-55mm.

When the distance between the forceps arm and the forceps handle is 2/3 of the length, the width of the forceps arm is gradually narrowed until the width of the forceps head is 1.0-1.5mm, and the sides and edges of the forceps arm are polished and polished to smooth. The design of the forceps arm ensures the strength of the forceps arm, ensures that the forceps head can smoothly clamp the miniature lens, and improves the operation comfort level to improve the efficiency.

After the forceps heads are engaged, the two front end faces of the forceps heads are polished to enable the tops of the forceps heads to be flush.

The inner side surface of the forceps head 4 is a clamping surface. On the inner side of about 1mm away from the front end face of the forceps head 4, drill bits with different diameters are utilized to respectively drill grooves corresponding to the miniature lenses with different diameters, so that the cylindrical surfaces of the cylindrical lenses can be clamped conveniently. Meanwhile, the grooves arranged at the position of about 1mm can play a role in protecting, damage to the miniature lens is avoided, and the hard damage degree to the lens is reduced while static electricity is prevented.

The tweezers of this embodiment use bamboo as the material. The characteristics of good toughness and easy bending of bamboo are fully utilized, and the tweezers arms can deform freely according to the force for clamping the lenses, so that the tweezers can be flexibly operated in the clamping process. The common wood has relatively hard texture and poor toughness, and the prepared forceps arms are not easy to bend and deform, so that the forceps arms are very inconvenient to clamp the micro lenses.

The overall weight of the forceps of this example was 0.6g, which was significantly lower than that of the metal forceps. The overall length of the forceps is 65mm. The length of the forceps handles is 10mm, the lengths of the upper forceps arms 2 and the lower forceps arms 3 are 55mm, the widths are 5mm, the distance between the upper forceps arms 2 and the lower forceps arms 3 is 2mm, through repeated practical verification, the forceps made of bamboo materials are selected to ensure that the forceps are small, exquisite, flexible and convenient in whole, are used for clamping miniature lenses, are labor-saving, remarkably improve the clamping efficiency of the miniature lenses, and greatly reduce the damage rate of products caused by clamping.

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