Description

Laser cutting equipment

The invention relates to a laser cutting device, in particular to a laser cutting device with precise positioning and capable of simultaneously performing laser cutting and detecting after precise positioning.

In general, the line on the perimeter of the display panel utilizes an advanced optical electronic device, such as a laser cutting machine, to perform laser cutting of the lines to be cut around the perimeter of the panel. The main principle of the laser cutting machine is to use the high-energy laser pulse to locally heat the line on the panel, so that the material of the line is melted, thereby achieving the purpose of cutting and breaking the line. Conventional laser cutting machines generally belong to single-track laser cutting machines, and their main configuration is a mobile platform, a positioning device and a laser cutting machine for carrying a panel. The mobile platform is mounted on the Y-axis track, and the positioning device and the laser cutting machine are mounted on the X-axis track. The Y-axis rail can transport panels to the positioning device and under the laser cutting machine for laser cutting operations. However, since there is only a single X-axis track, only the panels on a Y-axis track can be machined, that is, even if another set of Y-axis tracks is added, only the panels on one Y-axis track can be positioned at a time and After laser cutting, the panel on the other set of Y-axis rails can be cut and processed. As a result, conventional laser cutting machines have a relatively long processing time and their production capacity is greatly limited.

In order to solve the problem of the long processing time of the single-track laser cutting machine, a two-track laser cutting machine was born. Similar to a single-track laser cutting machine, the dual-track laser cutting machine also has a moving platform, positioning device and laser cutting machine disposed on the Y-axis track. The difference is that the two-axis laser cutting frame is provided with two sets of X-axis tracks, one X-axis track is equipped with a positioning device and a laser cutting machine, and the other X-axis track is equipped with a positioning detecting device. Therefore, the laser cutting operation can be performed on the panel on one of the Y-axis rails by the positioning device on the X-axis rail and the laser cutting machine, and then transported to the position detecting device of the other X-axis rail. , this has The cut panel is positioned and detected. At this time, the panel on the other Y-axis track is simultaneously moved to the positioning device on the X-axis track and below the laser cutting machine for laser cutting and adding work. From this, it can be seen that the laser cutting machine, the positioning detecting device, and the like are respectively mounted on the two X-axis rails, and the laser cutting processing and the detecting processing can be simultaneously performed. Therefore, compared with the single-track laser cutting machine, the processing time can be greatly shortened.

However, although the two-track laser cutting machine has been able to significantly increase production capacity and shorten processing time, there are still technical bottlenecks that cannot further increase production capacity. The main reasons are basically two points. First, the conventional laser cutting machine, whether it is a monorail or a dual-track laser cutting machine, can only randomly check the results of laser cutting, that is, once some of the cutting is to occur The broken line is not cut or is not completely cut off, and even the line that does not need to be cut is cut, which may cause leakage current. Second, conventional laser cutting machines generally use a positioning device or a positioning system to adjust the position of the panel in the X-axis direction and the Y-axis direction. However, this type of positioning device or positioning system can only mark the alignment on the panel. Positioning for positional positioning does not completely ensure that the line to be cut on the panel is accurately positioned on the path of the laser cutting process, and thus there is still a lack of positioning offset, inaccuracy, and the like.

Therefore, how to improve the positioning accuracy of the laser cutting machine, and at the same time have a comprehensive detection circuit, which is a problem that people in the field are eager to solve.

Referring to the second to fourth figures, a schematic plan view showing the operation flow of the laser cutting apparatus in the first embodiment of the present invention is shown.

First, as shown in the second figure, the two panels 100 are transported from the previous process equipment by a feed transfer device (not shown) and transported separately to the two carriers 216 in the laser cutting device 200. on. Next, the computer control device commands the transfer device 210 to operate such that the upper loading platform 216 carries the panel 100 thereon to the image capturing position below the image capturing device 204. Next, referring to the third figure, when the panel 100 is located at the image capturing position below the image capturing device 204, the computer control device commands the image capturing lenses 204a/204b of the image capturing device 204 to perform a marking image capturing operation on the two panels 100, respectively. The images of the two alignment marks 106 in the two panels 100 are obtained. Thereafter, the computer control device performs image analysis on the image acquired by the image capturing lens 204a/204b, and determines whether the panel 100 has an angular deviation based on the analysis result. If the judgment result indicates that one of the panels 100 has an angular deviation, at this time, for the panel 100 with the angular deviation, the computer control device drives the loading platform 216 on which the panel 100 is placed to rotate at an angle θ to compensate the angular deviation of the panel 100. The pre-cut straight line 110 formed by the center point of the two alignment marks 106 on the panel 100 is just parallel to the processing line 230 formed by the center point of the laser light source 206a and the center point of the detecting lens 206b.

A line 110 to be cut in the area to be cut on the panel 100 is opposed. Moreover, while the panel 100 is passing under the laser cutting device 206 along the straight line, the computer control device drives the laser light source 206a to perform laser cutting on the line 104 on the panel, and simultaneously drives the detecting lens 206b to immediately after being cut. These lines 104 perform a route taking operation.

The detecting lens 206b transmits the image obtained in the line taking operation to the computer control device, causes the computer control device to perform image analysis, and determines whether the cut lines 104 meet the requirements according to the analysis result. When the computer control device determines that the cutting result of each panel 100 meets the requirements, for example, the lines 104 after being cut are indeed cut off, and the cutting route is not skewed beyond the preset range, the computer control device will notify A discharge transfer device transports the compliant panel 100 to a discharge position (not shown) and notifies the delivery device of the next process device to remove the panel 100. When the computer control device determines that the cutting result of one of the panels does not meet the requirements, for example, the cutting route deviates from the straight line 110 formed by the center point of the two registration mark 106 (that is, cuts), and the line 104 is not completely cut, cutting The width is too narrow or too wide, or is cut to the area where no cutting is required. At this time, the computer control device notifies the discharge transfer device, transports the panel 100 to the discharge position, and emits an alarm sound to notify the staff. The panel 100 is removed.

Please refer to the fifth drawing, which is a plan view showing a second embodiment of the laser cutting apparatus of the present invention.

In other words, the image taking line 320 of the image capturing device 304 (ie, the image taking route) and the processing line 330 (ie, the processing route) of the laser cutting detecting device 306 are two different and parallel to each other.

The image capturing device 304 includes two image taking lenses 304a/304b and is configured to be movable along the X axis. It should be noted that the number of image taking lenses and the manner of configuration are not intended to limit the present invention, and those skilled in the art may change as needed. The laser cutting detecting device 306 has a laser light source 306a and a detecting lens 306b arranged side by side with the laser light source 306a, and is configured to be both It can be moved along the X axis. The transfer device 310 has a first set of tracks 314 and two carrying platforms 316 for carrying the panel 100, wherein the first set of tracks 314 are disposed on the base 302 parallel to the Y axis, and the carrying platform 316 is disposed on the first The set of tracks 314 can be moved in the Y direction along the first set of tracks 314.

Then, the control of the computer control device commands the transfer device 310 to operate to make the two carriers thereon. The stage 316 transports the panel 100 thereon to the image taking position below the image taking device 304. Subsequently, the computer control device drives the image capturing lenses 304a/304b of the image capturing device 304 to move parallel to the X-axis direction and simultaneously perform a marking image capturing operation on the two panels 100 to obtain two pairs of the two panels 100, respectively. Mark the image of 106. Thereafter, the computer control device performs image analysis on the image acquired by the image capturing lens 204a/204b, and determines whether the panel 100 has an angular deviation based on the analysis result. If there is an angular deviation, the computer control device drives the carrier 316 to rotate at an angle θ to compensate for the angular deviation of the panel 100. Detailed operations such as detection and compensation are the same as those of the first embodiment, and therefore will not be described here.

Upon completion of the positioning operation of the panel 100, the computer control device will again drive the transfer device 310 to drive the carrier 316 to transport the panel 100 thereon to the processing area below the laser cutting device 306. Next, the laser light source 306a and the detecting lens 306b are driven to move along the processing straight line 330, and at the same time, the laser cutting and the route image capturing operation route image capturing operation are performed. Finally, the detecting lens 306b returns the image obtained in the line taking operation to the computer control device, causes the computer control device to perform image analysis, and determines whether the cut lines 104 meet the requirements according to the analysis result. As for how the computer control device determines whether the cutting result is in compliance with the requirements, it is the same as the first embodiment, and therefore will not be described here. .

The transfer device is moved to the base 402. The laser cutting detection device 406 has a laser light source 406a and an image capturing lens 406b, and the laser light source 406a and the image capturing lens 406b are juxtaposed together and fixed to the transfer mechanism. Wherein, the above-mentioned image taking lens 406b integrates the functions of positioning and image capturing, and therefore, there is no need to additionally provide an image capturing device for positioning and capturing images.

The laser cutting apparatus of the third embodiment is mainly applied to a large-sized panel. First, the panel 100 is placed on the stage, after which the computer control device commands the transfer device to transport the laser cutting detection device 406 thereon to the area of the panel 100 to be cut to facilitate the marking and image taking operation. Next, when the laser cutting detecting device 406 passes over the area to be cut of the panel 100, the computer control device drives the image capturing device 406b to perform a mark taking operation to obtain an image of the two-aligned mark 106. Subsequently, the computer control device performs image analysis on the image acquired by the image capturing lens 406b, and determines whether the panel 100 has an angular deviation based on the analysis result. If there is an angular deviation, the computer control device drives the transfer device to adjust the moving path of the laser light source 406a and the image capturing lens 406b so that the center point of the laser light source 406a and the center point of the image capturing lens 406b are exactly aligned with the two alignment marks. One of the center points of 106 constitutes a pre-cut straight line 110. This completes the positioning of the panel 100.

After the positioning operation of the panel 100 is completed, the computer control device drives the transfer device again to drive the laser light source 406a and the image capturing lens 406b thereon to be transported over the area to be cut of the panel 100, and the laser light source 406a and The image taking lens 406b moves in a straight line. At this time, while the laser light source 406a and the image capturing lens 406b pass through the area to be cut of the panel 100 in a straight line, the computer control device drives the laser light source 406a to perform laser cutting on the lines 104 on the panel 100, and simultaneously drive The detecting lens 406b immediately performs a route image capturing operation on the lines 104 after cutting. As for how the computer control device determines whether the cutting result is in compliance with the requirements, it is the same as the first embodiment, and therefore will not be described here. .

Therefore, the laser cutting device disclosed in the present invention can not only accurately design the desired cutting line on the panel to be processed by the laser cutting process by the θ angle rotation of the transfer device and the design of the computer control device. Thereby improving the accuracy of positioning.
