Description

Technical Field

[0001] The utility model belongs to the technical field of laser processing equipment, and in particular relates to automatic sticker equipment for a laser cutting machine. Background Art

[0002] As a new type of thermal cutting technology, laser cutting technology has been widely used in the field of cutting and processing technology due to its advantages of fast cutting speed, high production efficiency, good cutting end surface quality, small heat-affected zone and environmental protection. Moreover, when using laser cutting technology to process metal plates, coils, etc., as the demand for laser marking and labeling by sheet metal terminal processing customers is becoming more and more widespread, the existing laser cutting production line is generally equipped with marking equipment in addition to the necessary laser cutting equipment, and the laser marking equipment is used to mark the plates before or after cutting.

[0003] At present, most of the QR codes used in existing laser cutting production lines are inkjet or laser coding, but both of the above coding methods have certain defects: 1. Since this coding method directly sprays the QR code onto the steel plate through the inkjet marking equipment, it is easy to scratch, which makes the subsequent scanning equipment unable to accurately recognize the QR code; 2. Since laser coding directly prints the QR code or the mark to be recognized onto the plate by removing the material by laser, although laser coding solves the shortcomings of inkjet coding, it creates new problems. It is easy to damage the surface of the plate and the overall cost is also high.

[0004] Therefore, laser cutting production lines on the market have gradually begun to use the method of sticking stickers on the workpiece to mark the workpiece, such as the diamond mesh labeling laser cutting machine provided in Chinese patent CN219336447U. However, due to the limited movement of the suction cup in the device, it is impossible to actively approach the label paper output by the label printer horizontally. When it only relies on the suction force generated by the suction cup and the airflow blown out by the positive pressure pipeline to absorb the label paper, it has high requirements for the airflow output by the positive pressure pipeline. Otherwise, the label paper will be easily blown off or blown away, or the label paper will not be blown into place, resulting in the suction cup being unable to accurately and firmly absorb the label paper. Utility Model Content

[0005] The technical problem solved by the utility model is to provide an automatic labeling device for a laser cutting machine which can accurately absorb label paper and label workpieces, so as to facilitate the laser cutting production line to process the workpieces.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: an automatic sticker device for a laser cutting machine, which includes a marking machine bracket, one end of the marking machine bracket is provided with a Z-axis connecting part that can be installed on the Z-axis bracket of the laser cutting machine, and the other end of the marking machine bracket is provided with a printer and a sticker assembly; the sticker assembly includes a vertical rotation drive mechanism installed on the marking machine bracket, a linear drive mechanism is installed at the power output end of the vertical rotation drive mechanism, a suction cup mounting plate is installed at the power output end of the linear drive mechanism, at least one vacuum suction cup is installed on the suction cup mounting plate, and the vacuum suction cup can be close to the label suction position and the labeling position under the action of the linear drive mechanism and the vertical rotation drive mechanism.

[0007] At this time, when the laser cutting machine is subjected to labeling after the utility model is applied, it can first print the QR code on the label paper through the printer, and peel off the label paper through the automatic peeling function of the printer; then the vacuum suction cup is moved to the label suction position through the vertical rotation drive mechanism and the linear drive mechanism, and the label paper is sucked onto the vacuum suction cup under the action of the negative pressure pipeline connected to the vacuum suction cup; finally, the label paper is pasted to the corresponding plate through the joint operation of the vertical rotation drive mechanism and the linear drive mechanism. Moreover, in this process, since the utility model adopts a structure in which the linear drive mechanism is installed at the power output end of the vertical rotation drive mechanism, the vacuum suction cup in the utility model can not only have the vertical linear motion freedom, but also the horizontal linear motion freedom. When it performs the label suction action, it can control the vacuum suction cup to be close to the label paper to a certain extent to ensure that the vacuum suction cup can accurately and stably absorb the label paper.

[0008] Furthermore, the vertical rotation drive mechanism includes a rotating cylinder, the cylinder body of the rotating cylinder is installed together with the marking machine bracket, the power output end of the rotating cylinder is installed together with the linear drive mechanism, and can drive the linear drive mechanism and the vacuum suction cup to rotate under the action of the rotating cylinder.

[0009] Furthermore, the linear drive mechanism includes a linear drive cylinder, a cylinder body of the linear drive cylinder is installed together with the power output end of the rotary drive mechanism, and the power output end of the linear drive cylinder is installed together with the suction cup mounting plate, and can drive the suction cup mounting plate and the vacuum suction cup to perform linear motion under the action of the linear drive cylinder.

[0010] Furthermore, the linear drive cylinder is a dual-axis cylinder to improve the movement stability of the suction cup mounting plate and the vacuum suction cup.

[0011] Furthermore, the vacuum suction cup is connected to a vacuum generating device through a negative pressure pipeline, and suction is provided to the vacuum suction cup through the vacuum generating device.

[0012] Furthermore, the marking machine bracket includes a front plate, the front end of which is installed with a printer and a sticker assembly, a side plate is provided at each of the left and right ends of the front plate, the rear ends of the two side plates are provided as a Z-axis connection part, and the space between the two side plates is provided as a laser head installation part. At this time, the entire marking machine bracket presents a "door"-shaped structure, and it can protect the laser head assembly of the laser cutting machine through the side plates.

[0013] Furthermore, the Z-axis connecting portion is provided with at least one mounting hole, and is mounted on the Z-axis bracket of the laser cutting machine via a fastener penetrating the mounting hole.

[0014] Furthermore, the printer is a thermal printer.

[0015] Furthermore, an air pipe bracket is installed on the bracket of the marking machine, and an air blowing pipeline is installed on the air pipe bracket. The air outlet of the air blowing pipeline is located on the side of the label paper output by the printer away from the sticker assembly, and the label blowing action is performed when the vacuum suction cup performs the label suction action to assist the vacuum suction cup in the label suction action. Moreover, in this process, since the vacuum suction cup itself in the utility model can move in the direction close to the label paper, compared with the prior art, the utility model can appropriately reduce the airflow requirements of the air blowing pipeline, avoiding the problem of the label paper being blown off or blown away or the label paper not being blown into place.

[0016] Furthermore, the air inlet end of the air blowing pipeline is connected to an air source and is provided with gas through the air source.

[0017] It can be seen from the above technical scheme that the utility model has the following advantages: when the laser cutting machine is applied with the utility model for labeling operation, it can first print the QR code on the label paper through the printer, and peel off the label paper through the automatic peeling function of the printer; then move the vacuum suction cup to the label suction position through the vertical rotation drive mechanism and the linear drive mechanism, and suck the label paper onto the vacuum suction cup under the action of the negative pressure pipeline connected to the vacuum suction cup; finally, the label paper is pasted to the corresponding plate through the joint operation of the vertical rotation drive mechanism and the linear drive mechanism. Moreover, in this process, since the utility model adopts a structure in which a linear drive mechanism is installed at the power output end of the vertical rotation drive mechanism, the vacuum suction cup in the utility model can not only have vertical linear movement freedom, but also have horizontal linear movement freedom. When it performs the label suction action, it can control the vacuum suction cup to be close to the label paper to a certain extent, reduce the distance between the vacuum suction cup and the label paper, and appropriately reduce the air flow requirements of the blowing pipeline to ensure that the vacuum suction cup can accurately and stably absorb the label paper, avoiding the problem of the label paper being blown off or blown away or the label paper not being blown into place.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] like Figure 1As shown, the first embodiment provides a first automatic sticker device for a laser cutting machine, which includes a "door"-shaped marking machine bracket 2, the marking machine bracket 2 includes a front plate 5, and the front end of the front plate 5 is installed with a printer 3 and a sticker assembly 4, and the left and right ends of the front plate 5 are each provided with a side plate 6, and the space between the two side plates 6 is set as a laser head mounting part capable of accommodating a laser head assembly, and the rear ends of the two side plates 6 are set as a Z-axis connecting part 7 that can be installed on the Z-axis bracket 1 of the laser cutting machine, and the Z-axis connecting part 7 is provided with at least one mounting hole. In this way, since the marking machine bracket 2 in the first embodiment presents a "door"-shaped structure as a whole, it can not only protect the laser head assembly of the laser cutting machine through the side plate 6, but also improve the stability of the printer 3 and the sticker assembly 4.

[0027] like Figure 2 As shown, the sticker assembly 4 includes a vertical rotation drive mechanism installed on the front plate 5 of the marking machine bracket 2, and the vertical rotation drive mechanism preferably adopts a rotary cylinder 8, and the cylinder body of the rotary cylinder 8 is installed together with the marking machine bracket 2, and a linear drive mechanism is installed at the power output end of the rotary cylinder 8. The linear drive mechanism preferably adopts a linear drive cylinder 9, and the linear drive cylinder 9 preferably selects a double-axis cylinder, and the cylinder body of the linear drive cylinder 9 is installed together with the power output end of the rotary cylinder 8, and a suction cup mounting plate 10 is installed at the power output end of the linear drive cylinder 9, and at least one vacuum suction cup is installed on the suction cup mounting plate 10, and the vacuum suction cup is connected to a vacuum generating device through a negative pressure pipeline, and the vacuum suction cup can approach the label suction position and the labeling position under the action of the linear drive mechanism and the vertical rotation drive mechanism.

[0028] At this time, when the laser cutting machine is applied with the present embodiment 1 and performs labeling operation, it can first print the QR code on the label paper 13 through the printer, and peel off the label paper 13 through the automatic peeling function of the printer 3; then move the vacuum suction cup to the label suction position through the vertical rotation drive mechanism and the linear drive mechanism, and suck the label paper 13 onto the vacuum suction cup under the action of the negative pressure pipeline connected to the vacuum suction cup; finally, the label paper 13 is pasted to the corresponding plate through the joint operation of the vertical rotation drive mechanism and the linear drive mechanism. In addition, in this process, since the present embodiment 1 adopts a structure in which the linear drive mechanism is installed at the power output end of the vertical rotation drive mechanism, the vacuum suction cup in the present embodiment 1 can not only have the vertical linear motion freedom, but also the horizontal linear motion freedom. When it performs the label suction action, it can control the vacuum suction cup to be close to the label paper to a certain extent to ensure that the vacuum suction cup can accurately and stably absorb the label paper.

[0030] like Figure 3 , Figure 4 As shown, the second embodiment provides a second type of automatic sticker pasting device for a laser cutting machine, and compared with the first type of automatic sticker pasting device for a laser cutting machine provided in the first embodiment, the difference is that the second embodiment further includes an additional blowing structure.

In addition, in this process, since the vacuum suction cup itself in the second embodiment can move toward the direction close to the label 13, compared with the prior art, the second embodiment can appropriately reduce the air flow requirements of the air blowing pipeline 12 to avoid the problem of the label 13 being blown off or blown away or the problem of the label 13 not being blown into place.
