Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, and more specifically, to a laser cutting device for producing aluminum veneer panels. Background Art

[0002] In the production of aluminum veneer panels, cutting is a crucial and essential core process. It directly determines the final shape and size of the aluminum veneer and forms the basis for subsequent processes such as bending, welding, and polishing. A laser cutting device utilizes laser technology to cut and size aluminum veneer panels.

[0003] Existing laser cutting devices, when it comes to cutting non-linear shapes, have complex and diverse cutting paths, potentially arc-shaped or wavy. This places extremely high demands on cutting precision and craftsmanship, making cutting difficult. Manual cutting also has low stability, making it difficult to guarantee consistent precision and quality every time. Different batches of aluminum veneer may require cutting different shapes, and the laser cutting units of some laser cutting devices require continuous, complex, and frequent displacement operations, resulting in higher maintenance costs. Furthermore, existing laser cutting devices struggle to meet complex cutting requirements, such as automatic loading and unloading, efficient cutting, and cutting different shapes. Summary of the Invention

[0004] The present invention aims to overcome the defects of the prior art and provides a laser cutting device for producing aluminum veneer.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a laser cutting device, comprising a bottom bracket, two limiting parts, a base, a slide mounted on the base, a slide driving unit for driving the slide to move in translation, a mounting seat located above the slide, a bearing seat mounted on the mounting seat, a bearing seat driving unit for driving the bearing seat to move in translation, a plurality of first vacuum adsorption units mounted on the bearing seat, an inverted U-shaped frame fixedly connected to both limiting parts, a lifting driving unit mounted on the inverted U-shaped frame, and a laser cutting unit mounted on the lifting driving unit; a lower strip-shaped protrusion with a strip-shaped slide groove is fixed on the slide, and the mounting seat is fixed on the bottom bracket. An upper strip protrusion with a strip slide rail is fixed; a strip protrusion with a strip limit groove is fixed on the slide seat, and a lower slider is installed in the strip limit groove, and the lower slider and the two ends of the strip limit groove are connected with springs, and the lower slider is connected to the U-shaped seat through a lower connecting column, and an installation slider and an installation slider driving unit for driving the installation slider to translate are installed on the U-shaped seat, and the installation slider is connected to the upper slider through an upper connecting column, and the mounting seat has a strip limit rail that cooperates with the upper slider; the limiting part includes a limiting plate, and the gap between the limiting plates of the two limiting parts constitutes a limiting path that can be passed by the upper connecting column.

[0006] Furthermore, the two limiting parts are both installed on the bottom bracket.

[0007] Furthermore, the base is fixed to the bottom bracket.

[0008] Furthermore, the lower connecting column and the upper connecting column are both cylindrical.

[0011] This allows the aluminum veneer to be adsorbed, making its movement more stable.

[0012] Furthermore, the number of the strip-shaped protrusions is one or more.

[0013] In some embodiments, the number of the strip-shaped protrusion is only one.

[0014] In this case, since the limiting path and an upper connecting column are used in conjunction to limit the position, the limiting path has a wider range of uses. No matter what type of limiting path, it can be limited by a single upper connecting column. Therefore, under the limiting action of the limiting path and the upper connecting column, the mounting seat can move left and right, so that the final cut shape of the aluminum veneer matches the shape of the limiting path.

In this case, although the selectable limit path is limited, more than two upper connecting columns and the limit path cooperate with each other to drive the left and right displacement of the mounting seat, which makes the drive of the left and right displacement of the mounting seat more stable.

[0082] Working principle: In the laser cutting device of the present application, the aluminum veneer to be cut is placed in the storage unit, and the positions of the four positioning plates are adjustable, so that the aluminum veneer stored therein can be accurately positioned, and the aluminum veneer to be cut can be transported to the supporting seat by the material transfer unit using the second vacuum adsorption unit and the second electric lifting rod. Since the aluminum veneer in the storage unit is accurately positioned, the position of the aluminum veneer at the supporting seat after being moved by the material transfer unit is also determined. Figure 1-9 As shown, the aluminum single plate is placed on the supporting seat and fixed by a plurality of first vacuum adsorption units. Figure 11 As shown in FIG, the bearing seat moves to between the two limiting parts, and the aluminum single plate has not been cut yet. Figure 14As shown, the relative positions of the supporting seat and the mounting seat remain unchanged. The slide is moved by using a slide drive unit, so that during the movement of the slide, due to the limitation of the limiting path, the upper connecting column can move along the limiting path (since the length of the slide is greater than the length of the limiting path, there are always multiple upper connecting columns located in the limiting path, and the upper connecting columns in the limiting path are located at the same point in different periods in the limiting path, so that as the slide moves, the limiting effect of the limiting path on different upper connecting columns is the same. And because the installation slider drive unit can adjust the position of the installation slider, the position of the upper connecting column can be adjusted, so that multiple upper The connecting column can better adapt to the limit path, ensuring that each upper connecting column in the limit path is located at the same point in different cycles of the limit path (the limit path does not need to have an upper connecting column in every cycle, it only needs to have an upper connecting column in some cycles). As the slide moves, under the action of the upper connecting column and the limit path, the mounting seat will move left and right, thereby cutting along the direction of the limit path). As a result, the whole formed by the mounting seat and the bearing seat will move left and right, and the cutting position of the laser cutting unit remains unchanged, so that the aluminum veneer is cut by the laser cutting unit, and the cut shape matches the shape of the limit path. Then as Figure 17 As shown, after cutting is completed, the first electric lifting rod can drive the first lifting plate to rise and fall, thereby driving the two rotating plates to rotate upward. At this time, the first vacuum adsorption unit is released, and the two cut aluminum veneers can slide to the sides and fall into the two unloading containers, completing the unloading. The slide and support base can then be reset to the position ready to receive the next aluminum veneer, so that the next aluminum veneer can be cut.

[0083] The cutting limit path of the present invention is adjustable. Driven by a multi-stage electric telescopic rod, the translation frame can be moved backward. The drive motor then rotates the rotating cylinder, causing the other limit plate to face the base. The multi-stage electric telescopic rod is then extended, moving the translation frame to the working position. The two limit plates then define a new limit path, allowing cutting of different shapes.

[0084] Although the present invention has been illustrated and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
