Description

Auxiliary device for small laser engraving machine

Technical Field

The utility model relates to a small-size laser engraving machine field, specific auxiliary device that small-size laser engraving machine used that says so.

Background

The main working mode of the small laser engraving machine is to engrave different parts of an object by controlling the translation of a laser head. However, the range of movement of the laser head is limited by the size of the machine and the facets are generally planar and do not engrave the perimeter of the cylindrical object. In the prior art, various patterns are carved on a plurality of thin cylindrical objects, most of the patterns on the cylindrical objects are carved manually through laser, so that workers are required to have good skills, the thinner objects are carved more strenuously, the patterns are often carved unevenly, defective products are caused by slight errors, and the qualified rate of products is very low. Also, for large-sized engravings, such as large-sized banners for advertisements, engraving can be performed only a plurality of times, which means that engraving effect cannot be guaranteed. Therefore, small laser engravers present great difficulties for engraving large format or cylindrical surfaces.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The examples are detailed below: as shown in fig. 1 and 2, the utility model provides an auxiliary device for a small laser engraving machine, which is characterized in that the device comprises a roller a (1), a roller B (2), a roller C (3) and a motor, wherein the motor is controlled by the small laser engraving machine and is used for driving the rotation of the roller a (1), the roller B (2) and the roller C (3); the position relation of the roller A (1) and the roller B (2) is up and down, the rotation directions of the roller A (1) and the roller B (2) are opposite, and the roller A (1) and the roller B (2) are used for drawing an engraved object placed between the roller A (1) and the roller B (2) to do linear motion; the position relation of the roller B (2) and the roller C (3) is parallel on the same level, the rotation directions of the roller B (2) and the roller C (3) are the same, and the roller B and the roller C are used for driving the cylindrical carved object placed on the roller B (2) and the roller C (3) to rotate; the roller A (1) is not fixedly installed and is movable and supported by an L-shaped support frame which is very easy to disassemble, when the device drives the carved object to rotate by using the roller B (2) and the roller C (3), the roller A (1) is not disassembled, and if the roller A (1) and the roller B (2) are required to pull the carved object to do linear motion, the roller A (1) is installed.

The specific operation process is divided into two cases:

firstly, describing the engraved object for engraving the cylindrical shape, wherein the roller A (1) is removed, the motor drives the roller B (2) and the roller C (3) to rotate in the same direction, so as to drive the engraved object placed above the roller B (2) and the roller C (3) to rotate, the laser head is always aligned above the engraved object, and the laser head finishes engraving the whole cylindrical surface of the engraved object along with the rotation of the engraved object.

Secondly, looking at large-width carved objects, for example, the advertisement banner is 300mm wide and 5m long, at this time, a roller A (1) needs to be installed, the narrow side of the banner is placed between the roller A (1) and a roller B (2), then the roller A (1) and the roller B draw the banner to move linearly and remotely, and along with the linear movement of the banner, a laser head finishes carving the whole banner.

It should be noted that, the roller a (1) is not fixedly installed, is movable, and is very easy to disassemble, and the supporting method includes two methods:

firstly, an L-shaped support frame structure as shown in fig. 1, 2 and 3 is adopted, L-shaped support feet on two sides of a roller a (1) are placed in support holes on two sides of a base, under the condition that the roller a (1) is heavy enough, a gear of the roller a (1) is meshed with a gear of a roller B under the action of self gravity, the roller B can drive the roller a (1) to rotate, and the rotation directions of the two are opposite; of course, if necessary, if the roller a (1) is too light, the roller B cannot drive the roller a (1) to rotate, and then a set screw may be additionally fastened to fix the roller a (1).

Secondly, the roller a (1) can be driven to rotate by the roller B under the action of self gravity even if the roller a (1) is heavy enough, such as the U-shaped grooves on both sides shown in fig. 4, but the disadvantage is that the size of the cylindrical carved object is limited by the existence of the U-shaped grooves on both sides, which is not recommended.

In addition, in order to make the auxiliary device applicable to the engraved objects with different sizes and cylindrical shapes, there are two methods:

the distance between the roller B and the roller C (3) can be movably adjusted, and the distance is adjusted to be closer for engraving small size, and vice versa.

Two pairs of rollers B and rollers C (3) which are not adjustable in distance are installed on the auxiliary device, wherein one pair of rollers is close to each other and is suitable for small-size cylindrical carved objects, and the other pair of rollers is far from each other and is suitable for large-size cylindrical carved objects.
