DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them.

The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0026] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0027] Combination Figures 1 to 3 As shown, the utility model provides a multi-head precision engraving machine, which includes a base 10, a processing platform 20, a loading and unloading module 30, a Y-axis driving module 40, an X-axis driving module 50, a Z-axis driving module 60 and a rotating manipulator 70; wherein the Y-axis driving module 40 is arranged on the base 10, and the processing platform 20 is installed on the Y-axis driving module 40, and the processing platform 20 is driven to realize reciprocating motion in the Y-axis direction by the drive of the Y-axis driving module 40; an outer shell is arranged on the outside of the base 10, and the entire multi-head precision engraving machine is wrapped by the outer shell.

[0028] Combination Figure 2 As shown, a gantry is installed on the base 10, and the X-axis drive module 50 is installed on the gantry, so that the X-axis drive module 50 is laid above the Y-axis drive module 40, and multiple Z-axis drive modules 60 are installed side by side on the X-axis drive module 50, and a processing spindle 601 is installed correspondingly under each Z-axis drive module 60; in this embodiment, three Z-axis drive modules 60 are arranged side by side on the X-axis drive module 50, with a total of three processing spindles 601, so the multi-head precision engraving machine is a three-head precision engraving machine in this embodiment; it should be noted that the number of Z-axis drive modules and processing spindles 601 can be adjusted according to actual needs.

[0029] In the above-mentioned embodiment, for the Y-axis drive module 40, the X-axis drive module 50 and the Z-axis drive module 60, a structure in which a linear motor cooperates with a lead screw and a slide rail in the prior art is adopted. Since this structure is very mature in the prior art, the multi-head precision engraving machine of the utility model does not improve or adjust the structure of the Y-axis drive module 40, the X-axis drive module 50 and the Z-axis drive module 60 itself, so its structure is no longer described in detail in this embodiment.

[0030] Furthermore, the loading and unloading module 30 is installed on the base 10 and is located on one side of the processing platform 20; in this embodiment, the loading and unloading module 30 is arranged on one side of the processing platform 20 along the Y-axis direction, and the processing platform 20 can reciprocate in the Y-axis direction. The position design of the loading and unloading module 30 makes it as close to the processing platform 20 as possible, reducing the turnover time of loading and unloading workpieces, thereby improving the loading and unloading efficiency. The specific structure of the loading and unloading module 30 will be further described below.

[0031] Furthermore, the rotary manipulator 70 is located above the loading and unloading module 30 and the processing platform 20. The rotary manipulator 70 includes multiple groups of suction cups 701 and a power component that drives the suction cups 701 to achieve displacement. The suction cups 701 are used to load and unload the workpiece between the processing platform 20 and the loading and unloading module 30. In this embodiment, the power component is a rotary drive motor 702; Figure 3 As shown, the rotating manipulator 70 also includes a first rotating arm 703, a second rotating arm 704, a rotating spindle 705 and a rotating support plate 706; one end of the first rotating arm 703 is fixedly connected to the motor shaft of the rotating drive motor 702, and the other end of the first rotating arm 703 is rotatably connected to one end of the second rotating arm 704, and the rotating spindle 705 is rotatably installed on the other end of the second rotating arm 704, and the first rotating arm 703 and the second rotating arm 704 are driven to rotate by the rotating drive motor 702; the rotating spindle 705 passes through and is fixed in the middle of multiple rotating support plates 706, and suction cup fixing plates 707 are fixedly installed at both ends of the rotating support plates 706, and the suction cup 701 is installed on the suction cup fixing plate 707.

[0032] Through the above structure, under the drive of the rotating drive motor 702, the first rotating arm 703 and the second rotating arm 704 can be driven to realize 360° rotation. Since the rotating main shaft 705 is rotatably installed at one end of the second rotating arm 704, the rotating main shaft 705 can be driven to realize the change of position; and, a power device for driving the rotating main shaft 705 to realize self-rotation, such as a driving motor, is arranged inside the second rotating arm 704; the rotating support plate 706 and the suction cup fixing plate 707 are driven to realize rotation through the rotating main shaft 705. Therefore, through this structure, the rotation of the rotary drive motor 702 can make the rotary spindle 705 reciprocate between the processing platform 20 and the loading and unloading module 30. At the same time, with the rotation of the rotary spindle 705, the efficiency of loading and unloading can be greatly improved; for example, when the suction cup 701 at one end of the rotating support plate 706 absorbs the glass workpiece to be processed, after the rotating spindle 705 moves above the processing platform 20, with the cooperation of the rotary drive motor 702 and the rotating spindle 705, the suction cup 701 at the other end of the rotating support plate 706 can first absorb the processed glass workpiece, and then place the glass workpiece to be processed on the processing platform 20. This method can reduce the standby time during the loading and unloading process.

[0033] Through the above structure, the multi-head precision engraving machine of the utility model can realize the simultaneous processing of multiple workpieces at the same time, thereby improving the processing efficiency. And due to the structural design of the rotating manipulator 70, it can drive the glass workpiece to realize 360° rotation, which is conducive to the loading and unloading of the workpiece, and the overall volume is relatively small. In addition, in the present embodiment, a fastening sleeve 708 is fixedly provided in the middle of the rotating support plate 706, and a fastening screw is provided on the fastening sleeve 708, and the rotating spindle 705 passes through the fastening sleeve 708 and is locked by the fastening screw; therefore, the number of rotating support plates 706 on the rotating spindle 705 can be adjusted according to actual conditions. For example, in the present embodiment, three processing spindles 601 are included, so a total of three rotating support plates 706 are fixed on the rotating spindle 705; therefore, this type of rotating manipulator 70 can be adapted to precision engraving machines with different numbers of spindles, and has strong adaptability.

[0034] Combination Figure 1 and Figure 2 As shown, for the above-mentioned loading and unloading module 30, the utility model provides a specific embodiment, the loading and unloading module 30 includes a parallel loading conveyor belt 301 and a unloading conveyor belt 302, and the conveying direction of the loading conveyor belt 301 and the unloading conveyor belt 302 is perpendicular to the Y axis; it can be understood that the loading and unloading module 30 also includes a motor, a roller shaft and other structures for driving the loading conveyor belt 301 and the unloading conveyor belt 302. Similarly, since this part is relatively mature in the prior art, it will not be described in detail in this embodiment. In addition, combined with Figure 3 As shown, a position for installing the loading and unloading module 30 is reserved at the end of the loading and unloading conveyor belt 301; through reasonable layout, the area occupied by the rotating manipulator 70 is reduced, making the layout of various components on the base 10 of the engraving machine more compact and reasonable.

[0035] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
