Description

Technical Field

[0001] The utility model relates to the technical field of edge-probing and cutting machines, in particular to a laser automatic edge-probing and cutting machine for billboard processing. Background Art

[0002] The laser automatic edge cutting machine uses the thermal energy of the laser to cut the material. The laser cutting head of the laser cutting machine has high cutting accuracy and faster cutting speed. It has a wide range of applications. The use of the laser automatic edge cutting machine in billboard processing technology integrates advanced laser technology and automatic control systems. It can efficiently and accurately complete the cutting tasks of various billboards. It has the characteristics of high precision, high speed and multi-function, bringing a new processing solution to the billboard production industry.

[0003] After searching, the applicant discovered a Chinese patent disclosure for "A Rapid Unloading Device for an Automatic Laser Edge Cutting Machine," with the publication (announcement) number "CN 214185781 U." This patent primarily utilizes a blower, an air pipe, and an air blowing head. When a piece of paper cut by the laser cutting head becomes stuck on the cardboard, the blower blows air through the air pipe to the air blowing head, which blows the stuck paper off the cardboard onto a collection mechanism. This eliminates the need for manual collection, thereby improving processing efficiency. However, the heat generated by the laser head in this device when cutting an object is difficult to dissipate. Under the concentrated high heat of laser cutting, if heat is not dissipated in time, the object being cut is prone to local deformation. Furthermore, during the cutting process, the object being cut will be affected by the movement of the laser head, the impact of the laser energy, and the stress release of the material itself, resulting in vibration and affecting cutting accuracy. Therefore, we propose a laser edge cutting machine for billboard processing. Utility Model Content

[0028] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Please see the attached Figure 1 -Attached Figure 7The utility model discloses an automatic laser edge cutting machine for billboard processing, which includes a frame 1, a guide rail 2 and a slide 3. The two sets of guide rails 2 are detachably mounted in a placement slot 101 provided on the left and right sides of the frame 1. The bottom ends of the two sides of the slide 3 are slidably connected with the two sets of guide rails 2. The slide 3 is located directly above the middle of the two sets of guide rails 2, and a laser head 9 that can move left and right is provided in the slide 3. The guide rail 2 can drive the slide 3 to move back and forth, thereby driving the laser head 9 to cut the billboard in the front and back positions. At the same time, the laser head 9 slides in the slide 3 and can cut the billboard in the left and right positions. The frame 1 directly below the slide 3 is in the shape of a through-hole, and a placement slot 2 102 is provided on the outer edge of the top of the through-hole of the frame 1 for placing A cutting platform 4 is fixedly connected to the top of the second slot 102, and a fan bracket 5 is provided just below the cutting platform 4. A cooling fan 6 is installed on a fan base 51 provided on the top of the fan bracket 5. A rectangular through slot 103 communicating with the through opening of the frame 1 is provided on the inner wall of the placement slot 101. Both ends of the fan bracket 5 pass through the rectangular through slot 103, and the tops of both ends of the fan bracket 5 are detachably connected to the bottoms of both ends of the slide 3, respectively, for driving the cooling fan 6 to move with the cutting position of the billboard. When the slide 3 drives the laser head 9 thereon to move back and forth to cut the billboard, it also drives the cooling fan 6 on the fan bracket 5 to move back and forth, so that the cooling fan 6 dissipates heat at the cutting position corresponding to the billboard just above;

[0030] A heat dissipation cavity 401 is provided at the bottom of the cutting platform 4, and a plurality of heat dissipation holes 402 are provided on the top of the cutting platform 4, which are connected to the heat dissipation cavity 401. An air guide groove 403 communicating with the heat dissipation holes 402 is also provided on the top of the cutting platform 4. A vent 404 is provided in the middle of the front side of the heat dissipation cavity 401, and a bottom plate 41 detachably connected to the cutting platform 4 is provided at the bottom of the heat dissipation cavity 401. The bottom plate 41 is provided with ventilation grooves 411 corresponding to the movement trajectory of the cooling fan 6. The wind generated by the cooling fan 6 can be diffused into the surrounding air guide grooves 403 through the heat dissipation holes 402, thereby increasing the heat dissipation area of ​​the billboard while preventing the billboard from being blown away.

[0031] A cavity 104 is provided on the rear side of the frame 1, and a circular opening 105 is provided on the front side of the cavity 104 and is connected to the second placement slot 102. An air cooler 7 is provided inside the cavity 104, and an air outlet pipe 71 provided on the front side of the air cooler 7 passes through the circular opening 105 and is closely connected to the vent 404. The cold air flow generated by the air cooler 7 further improves the heat dissipation effect of the billboard.

[0032] In the first embodiment, a guide roller 11 is provided on the inner wall of the opening of the frame 1 on the front side of the cutting platform 4. Four support blocks 12 are fixedly connected to the top of the frame 1. The four support blocks 12 are respectively arranged at the front and rear end positions of the top of the frame 1 on the left and right sides of the second placement slot 102. Cylinders 13 are provided on the tops of the four support blocks 12. The two front cylinders 13 and the two rear cylinders 13 each form a group. A pressure plate 14 is fixedly connected to the bottom of each group of cylinders 13.

[0033] Specifically, by setting the guide roller 11, the movement of the billboard is facilitated. By setting the cylinder 13 and the pressure plate 14, after the billboard is placed on the cutting platform 4, the cylinder 13 is started to drive the pressure plate 14 to move downward to fix the billboard. This avoids the billboard from shaking due to the movement of the laser head 9, the impact of laser energy, and the stress release of the material itself during the laser cutting process, which is conducive to improving the cutting accuracy.

[0034] In the second embodiment, a linear motor 21 is installed on the front side of each guide rail 2, and a screw rod 22 is installed on the rear output end of the linear motor 21 to be rotatably connected to the front and rear ends of the guide rail 2. Threaded holes matching the screw rod 22 are provided at the bottom ends of both sides of the slide 3, and a linear motor 2 31 is installed on the right side of the slide 3. A screw rod 2 32 is installed on the left output end of the linear motor 2 31 to be rotatably connected to the left and right ends of the slide 3. A slider 33 is provided on the screw rod 2 32, and a threaded hole matching the screw rod 2 32 is provided on the slider 33. The slider 33 slides in contact with the inner wall of the slide 3, and the bottom of the slider 33 is detachably connected to the laser head 9. A slide groove 202 connected to the guide cavity 201 is provided at the bottom of the guide rail 2, and the slide groove 202 slides in contact with the side end of the fan bracket 5. A controller 8 is provided on the top of the rear side of the frame 1.

[0035] Specifically, by installing the top ends of the fan bracket 5 on the bottom ends of the slide 3, when the slide 3 drives the laser head 9 on it to move back and forth to cut the billboard, it also drives the cooling fan 6 on the fan bracket 5 to move back and forth. The position directly above the cooling fan 6 corresponds to the position where the billboard is cut. The wind blown out can effectively reduce the temperature of the cutting platform 4, thereby reducing the temperature of the position where the billboard is cut, and the cooling fan 6 can diffuse the cold air flow discharged by the air cooler 7 into the air guide groove 403 through the heat dissipation hole 402. While strongly dissipating the heat at the cut position of the billboard, it can cool the billboard over a large area, thereby avoiding local deformation of the billboard due to untimely heat dissipation under the high heat concentration of laser cutting.

[0036] Working principle:

[0037] First, push the billboard to the top of the cutting platform 4 through the guide roller 11, and then start the cylinder 13 to drive the pressure plate 14 to move downward to fix the billboard. The linear motor 21 rotates forward to drive the slide 3 to move forward, thereby driving the laser head 9 to cut the billboard in the forward direction, and at the same time drives the cooling fan 6 on the fan bracket 5 to move forward and dissipate heat to the position where the billboard is cut. Conversely, the linear motor 21 reverses to drive the slide 3 to move backward, thereby driving the laser head 9 to cut the billboard in the backward direction, and at the same time drives the cooling fan 6 on the fan bracket 5 to move backward and dissipate heat to the position where the billboard is cut. During the process of the laser head 9 cutting the billboard forward and backward, the laser head 9 can move left and right in the slide 3 at the same time, that is, cut the billboard in the left and right directions. After the cutting is completed, start the cylinder 13 again to drive the pressure plate 14 to move upward and take out the cut billboard. At this point, the entire work flow ends.

[0038] The above-mentioned front, back, left, right, up and down are all based on the Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
