Description

Technical Field

[0001] This invention relates to the field of laser etching, and more specifically to a metal plate for use as a release film for decorative panels and its manufacturing process. Background Technology

[0002] Release film for decorative panels is a protective film temporarily adhered to the surface of decorative panels. It typically consists of a plastic substrate (such as PET, PE, PP, etc.) and a silicone oil coating (release layer) with special peel properties. The film is usually printed with brand logos, dimensions, model numbers, usage instructions (such as "remove after installation"), arrow directions, and other patterns for easy identification and installation.

[0003] In existing technologies, patterns on release films are generally printed using embossing technology. This involves pressing various textures onto a plastic substrate using an embossing roller during the release film production process. In the industry, embossing rollers are also known as metal plates. Their manufacturing process involves spraying a coating onto the outer surface of the roller, then using laser etching technology to precisely etch the pattern onto the coating. The roller is then placed in a chemical reagent; the areas not covered by the coating are corroded, while the areas covered by the coating are not. This process is repeated until a embossing roller meeting the preset requirements is obtained.

[0004] In existing laser etching technologies, such as Figure 1 As shown, since the embossing roller body a is large and heavy, it is necessary to extend an end shaft b coaxially from each end. The two end shafts b are clamped by two clamps respectively, and the embossing roller is driven to rotate. At the same time, the laser generator is driven to move axially. The two work together to achieve laser etching of the embossing roller. Most existing clamping technologies use three-jaw chucks, but there are some shortcomings in their use. Specifically, when clamping, the axial distance of the two end shafts b extending into the three-jaw chuck is different. Therefore, the embossing roller body a is prone to vibration during rotation. Vibration will affect the accuracy of the final laser etching. Since the vibration is uncontrollable, the final embossing roller still needs to be inspected to determine whether it is qualified.

[0005] Based on the above, the present invention proposes a metal plate for release film of decorative panels and its manufacturing process. Summary of the Invention

[0006] To address the problems mentioned in the background above, the present invention provides a metal plate for release film of decorative panels and its manufacturing process.

[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0008] A manufacturing process for a metal sheet used in release films for decorative panels:

[0009] Step 1: Spray a coating layer onto the outer surface of the embossing roller;

[0010] Step 2: Place the embossing roller in a laser etching machine and use the laser etching machine to etch the pattern on the coating on the outer surface of the embossing roller.

[0011] Step 3: Place the embossing roller in a chemical reagent. The parts of the embossing roller not covered by the coating will be corroded by the chemical reagent, while the parts covered by the coating will not be corroded by the chemical reagent.

[0012] Step 4: After the preset time, remove the embossing roller, and then repeat steps 1-3;

[0013] Step 5: Use an embossing roller to make a sample. If the sample is acceptable, the embossing roller is acceptable; otherwise, if the sample is unacceptable, the embossing roller is unacceptable.

[0014] A laser etching apparatus for performing a metal plate manufacturing process includes a bed, on which a laser component and a clamping mechanism are mounted. The clamping mechanism is used to clamp the end shaft b of an embossing roller and drive the embossing roller to rotate. The laser emitting end of the laser component can move along the axial direction of the embossing roller.

[0015] The clamping mechanism includes two clamping members arranged facing each other, a drive assembly for driving the two clamping members to move closer or further apart from each other, and a power source for providing rotational power to the clamping members.

[0016] The clamping component includes a clamping frame, and a rotating shaft is mounted on the upper end of the clamping frame. The axis of the rotating shaft is parallel to the length direction of the bed.

[0017] Each of the two clamping components has a rotating disk coaxially mounted at one end of its rotating axis facing each other, and a pressure sensor is mounted at the midpoint of the facing end faces of the rotating disks of the two clamping components.

[0018] Furthermore, the laser assembly includes a laser support and a linear module for driving the laser support to move. The direction of movement of the laser support is parallel to the length direction of the bed, and a laser generator is provided on the side of the laser support facing the center line of the clamping mechanism.

[0019] Furthermore, the drive assembly includes a main slide rail, a main lead screw, and a first motor for driving the main lead screw to rotate. The main lead screw is divided into two drive sections with opposite thread directions along its own axis. The axis of the main lead screw is parallel to the length direction of the bed, and the guiding direction of the main slide rail is parallel to the length direction of the bed.

[0020] The clamping frames of the two clamping components are threadedly connected to the two drive sections of the main lead screw, and the clamping frames of the two clamping components are slidably connected to the main slide rail.

[0021] Furthermore, the power source includes a spindle and a second motor for driving the spindle to rotate. The axis of the spindle is parallel to the length direction of the bed. The rotating shaft and the spindle are connected by a power transmission component. The driving component of the power transmission component is set on the spindle by a spline, and when the driving component moves axially, the spindle continuously outputs power to the driving component through the spline.

[0022] Furthermore, clamping components are provided on the opposing end faces of the rotating disks of the two clamping members, and three clamping components are arranged in an array along the circumference of the rotating disk on the same rotating disk.

[0023] Furthermore, the clamping assembly includes a fixed arm seat that is vertically fixed on the end face of the rotary disk. The fixed arm seat has a secondary slide rail and a secondary lead screw on the side facing the axis of the rotary disk, and the extension direction of both is parallel to the axis of the rotary disk.

[0024] A slide block is slidably mounted on the auxiliary slide rail. There are two slide blocks. The auxiliary lead screw is divided into two connecting sections with opposite thread directions along its own axis. The two slide blocks are respectively threadedly connected to the two connecting sections of the auxiliary lead screw.

[0025] Both slides have inclined surfaces on their opposite sides, and the distance between the two inclined surfaces increases in a direction perpendicular to the axis of the auxiliary lead screw and from the auxiliary lead screw toward the axis of the rotating disk. There is a push-pull seat between the two slides, and the two sides of the push-pull seat are respectively connected to the two inclined surfaces in a sliding connection along the inclined direction. A clamping seat is provided on the side of the push-pull seat facing the axis of the rotating disk.

[0026] Furthermore, the rotating shaft is hollow and contains a pneumatic motor. The pneumatic motor is connected to the lead screws of the three clamping components on the rotating disk via a reducer.

[0027] A laser etching apparatus for performing metal plate manufacturing processes, the working process of which includes the following steps:

[0028] S1: The area between the three clamping components of the clamping member is named the clamping area. The two end shafts b of the embossing roller are placed into the clamping areas of the two clamping members from top to bottom.

[0029] S2: The two clamping components are driven to move closer to each other by the drive component. During this process, the embossing roller can be centered and positioned. At the same time, the two end shafts b of the embossing roller will contact the pressure sensors of the two clamping components respectively. When the pressure values ​​detected by the two pressure sensors reach the same preset value, it means that the embossing roller has completed the centering and positioning, and the drive component stops running.

[0030] S3: The pneumatic motor starts, driving the three clamping components to move closer to each other, and the clamping area closes to achieve clamping of the end shaft b.

[0031] S4: The power source starts, driving the rotating shaft to rotate, which in turn rotates the embossing roller. During the rotation, if the values ​​detected by the two pressure sensors are the same or the difference is within the allowable range, then proceed to step five. If the values ​​detected by the two pressure sensors are out of range, then the machine needs to be stopped for maintenance.

[0032] S5: The laser component is activated and works with the rotating embossing roller to perform laser etching on the embossing roller. After a preset time, the laser etching is completed, and the embossing roller is removed.

[0033] During the laser etching process, if the values ​​detected by the two pressure sensors are the same or the difference is within the allowable range, then the product is qualified; if the values ​​detected by the two pressure sensors are outside the range, then the product is unqualified.

[0034] Compared with the prior art, the beneficial effects of this invention are as follows:

[0035] One of the core aspects of this solution lies in the laser etching of the embossing roller, specifically:

[0036] 1. During the clamping process of the embossing roller, the embossing roller can be centered and positioned. At the same time, the two end shafts b of the embossing roller will contact the pressure sensors of the two clamping components respectively. When the pressure values ​​detected by the two pressure sensors reach the same preset value, it means that the embossing roller has completed the centering and positioning. The drive component stops running, the pneumatic motor starts, and the end shaft b is clamped.

[0037] Its technical advantages are as follows: Firstly, the drive component will only stop running and begin clamping the end shaft b when both pressure sensors reach the same preset value, thus preventing accidental start-up. Secondly, it can ensure that the axial distance of the two end shafts b extending into the clamping area is consistent, solving the problem mentioned in the background technology that "when clamping, the axial distance of the two end shafts b extending into the three-jaw chuck is different, which can easily cause the embossing roller body a to vibrate during rotation, and the vibration will affect the accuracy of the final laser etching." Thirdly, the pre-centering positioning of the embossing roller during each laser etching can reduce the tool setting time and improve the laser etching efficiency.

[0038] 2. After clamping is completed, the power source is started, driving the rotating shaft to rotate, thereby rotating the embossing roller together for a preset time;

[0039] Its technical advantage lies in the following: If the machine malfunctions or the end shaft b is not clamped tightly, the end shaft b will deviate slightly during rotation, causing the values ​​detected by the two pressure sensors to no longer be consistent, but to differ. In other words, if the embossing roller is rotated for a preset time and the values ​​detected by the two pressure sensors are consistent or the difference is within the allowable range, it means that the clamping is stable, and then laser etching begins. Conversely, if there is a difference that exceeds the range, it means that the clamping is unstable or the machine malfunctions, and then the machine needs to be stopped for maintenance. This can determine whether the next laser etching step should be performed, and has a machine self-check function.

[0040] 3. The laser assembly is activated and works in conjunction with the rotating embossing roller to perform laser etching on the roller. After a preset time, the laser etching is completed. During this process, the technical advantage of the two pressure sensors is that if the values ​​detected by the two pressure sensors are consistent or the difference is within the allowable range, it indicates that there is no error in the laser etching process and the product is qualified. Conversely, it indicates that the product is unqualified. This process serves to detect the processing quality of the embossing roller. Attached Figure Description

[0052] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0053] A manufacturing process for a metal sheet used in release films for decorative panels includes the following steps:

[0054] Step 1: Spray a coating layer onto the outer surface of the embossing roller;

[0055] Step 2: Place the embossing roller in a laser etching machine and use the laser etching machine to etch the pattern on the coating on the outer surface of the embossing roller.

[0056] Step 3: Place the embossing roller in a chemical reagent. The parts of the embossing roller not covered by the coating will be corroded by the chemical reagent, while the parts covered by the coating will not be corroded by the chemical reagent.

[0057] Step 4: After the preset time, remove the embossing roller, and then repeat steps 1-3 until an embossing roller that meets the preset requirements is obtained;

[0058] Step 5: Use an embossing roller to make a sample. If the sample is acceptable, the embossing roller is acceptable; otherwise, if the sample is unacceptable, the embossing roller is unacceptable.

[0059] Reference Figure 2 and Figure 3 A laser etching apparatus for performing metal plate manufacturing processes includes a bed 100, on which a laser assembly 200 and a clamping mechanism 300 are mounted. The clamping mechanism 300 is used to clamp the end shaft b of the embossing roller and drive the embossing roller to rotate. The laser emitting end of the laser assembly 200 can move along the axial direction of the embossing roller. The two work together to achieve laser etching of the embossing roller.

[0060] Reference Figure 4The laser assembly 200 includes a laser support 202 and a linear module 201 for driving the laser support 202 to move. The direction of movement of the laser support 202 is parallel to the axial direction of the embossing roller held by the clamping mechanism 300, that is, parallel to the length direction of the bed 100. The linear module 201 can be realized by existing lead screw linear movement technology, which will not be described in detail. A laser generator 203 is provided on the side of the laser support 202 facing the center line of the clamping mechanism 300. The laser generator 203 can be realized by existing technology, which will not be described in detail.

[0061] Reference Figure 4 The clamping mechanism 300 includes two clamping members 305 arranged facing each other, a drive assembly for driving the two clamping members 305 to move closer to or further away from each other, and a power source for providing rotational power to the clamping members 305.

[0062] Reference Figure 4 and Figure 5 The drive assembly includes a main slide rail, a main lead screw 303, and a first motor 301 for driving the main lead screw 303 to rotate. The main lead screw 303 is divided into two drive sections with opposite thread directions along its own axis. The axis of the main lead screw 303 is parallel to the length direction of the bed 100, and the guide direction of the main slide rail is parallel to the length direction of the bed 100.

[0063] The clamping member 305 includes a clamping frame 306. The clamping frames 306 of the two clamping members 305 are respectively threadedly connected to the two driving sections of the main lead screw 303. The clamping frames 306 of the two clamping members 305 are slidably connected to the main slide rail. Therefore, when the main lead screw 303 is driven to rotate by the first motor 301, the clamping frames 306 of the two clamping members 305 will move away from each other or move closer to each other, thereby causing the two clamping members 305 to move closer to each other or away from each other.

[0064] Reference Figure 4 and Figure 6 The power source includes a spindle 304 and a second motor 302 for driving the spindle 304 to rotate. The axis of the spindle 304 is parallel to the length direction of the bed 100.

[0065] The clamping component 305 also includes a rotating shaft 307 mounted on the upper end of the clamping frame 306. The axis of the rotating shaft 307 is parallel to the length direction of the bed 100. The rotating shaft 307 and the spindle 304 are connected by a power transmission component. The driving component of the power transmission component is set on the spindle 304 by a spline. When the driving component moves axially, the spindle 304 continuously outputs power to the driving component through the spline, that is, continuously outputs power to the rotating shaft 307.

[0066] Reference Figures 6-9The rotating shaft 307 is hollow and contains a pneumatic motor 310.

[0067] Each of the two clamping members 305 has a rotating disk 308 coaxially arranged at one end of its rotating shaft 307 facing each other. Each of the two clamping members 305 has a clamping component 309 arranged on the facing end face of the rotating disk 308. Three clamping components 309 on the same rotating disk 308 are arranged in an array along the circumference of the rotating disk 308.

[0068] Reference Figure 9 The clamping assembly 309 includes a fixed arm seat 3091 that is vertically fixed on the end face of the rotary disk 308. The fixed arm seat 3091 is provided with a secondary slide rail and a secondary lead screw 3093 on the side facing the axis of the rotary disk 308, and the extension direction of both is parallel to the axis of the rotary disk 308.

[0069] There are two slide blocks 3092 on the secondary slide rail.

[0070] The auxiliary lead screw 3093 is divided into two connecting sections with opposite thread directions along its own axis. The two slides 3092 form threaded connections with the two connecting sections of the auxiliary lead screw 3093 respectively.

[0071] The pneumatic motor 310 and the auxiliary lead screws 3093 of the three clamping assemblies 309 on the rotary disk 308 are connected by a reducer 311. Therefore, when the auxiliary lead screws 3093 are rotated by the pneumatic motor 310, the two slides 3092 move closer to each other or further away from each other.

[0072] Both slides 3092 have inclined surfaces on their opposite sides, and the distance between the two inclined surfaces increases along the direction perpendicular to the axis of the auxiliary lead screw 3093 and from the axis of the auxiliary lead screw 3093 toward the axis of the rotating disk 308.

[0073] A push-pull seat 3094 is located between the two slides 3092. The two sides of the push-pull seat 3094 are respectively connected to the two inclined surfaces in a sliding connection along the inclined direction. Therefore, when the two slides 3092 move closer to each other or further away from each other, the push-pull seat 3094 moves closer to or further away from the axis of the rotating disk 308.

[0074] A clamping seat 3095 is provided on the side of the push-pull seat 3094 facing the axis of the rotating disk 308.

[0075] Furthermore, refer to Figure 8In the three clamping components 309 of the same rotating disk 308, when one of the clamping components 309 is located at the lowest point of the outer circular surface of the rotating disk 308, a limiting plate 3081 is provided between this clamping component 309 and the remaining two clamping components 309, and the upper area between the remaining two clamping components 309 is open. Therefore, the end shaft b of the embossing roller can be directly placed between the three clamping components 309 from top to bottom and is initially supported by the lowest clamping component 309.

[0076] Furthermore, refer to Figure 8 A pressure sensor 312 is provided at the middle position of the opposite end faces of the rotating disks 308 of the two clamping components 305.

[0077] The working principle of laser etching equipment is as follows:

[0078] Step 1: The area between the three clamping components 309 of the clamping member 305 is named the clamping area;

[0079] By using hoisting equipment or manual labor, the two end shafts b of the embossing roller are placed directly from top to bottom into the clamping areas of the two clamping components 305, and are initially supported by the lowest clamping component 309.

[0080] Step 2: The two clamping components 305 are driven to move closer to each other by the drive component. During this process, the embossing roller can be centered and positioned. At the same time, the two end shafts b of the embossing roller will contact the pressure sensors 312 of the two clamping components 305 respectively. When the pressure values ​​detected by the two pressure sensors 312 reach the same preset value, it means that the embossing roller has completed the centering and positioning, and the drive component stops running.

[0081] Step 3: The pneumatic motor 310 starts, driving the three clamping components 309 to move closer together, the clamping area closes, and the end shaft b is clamped.

[0082] Its technical advantages are as follows: Firstly, the drive component will only stop running and begin clamping the end shaft b when both pressure sensors 312 reach the same preset value, thus preventing accidental start-up. Secondly, it can ensure that the axial distance of the two end shafts b extending into the clamping area is consistent, solving the problem mentioned in the background technology that "when clamping, the axial distance of the two end shafts b extending into the three-jaw chuck is different, which can easily cause the embossing roller body a to vibrate during rotation, and the vibration will affect the accuracy of the final laser etching." Thirdly, the pre-centering positioning of the embossing roller during each laser etching can reduce the tool setting time and improve the laser etching efficiency.

[0083] Step 4: The power source is started, driving the rotating shaft 307 to rotate, which in turn rotates the embossing roller. Its technical advantage is that if the machine malfunctions or the clamping of the end shaft b is not tight, the end shaft b will deviate slightly during the rotation, causing the values ​​detected by the two pressure sensors 312 to no longer be consistent, but to have a difference. That is to say, the embossing roller is first rotated for a preset time. If the values ​​detected by the two pressure sensors 312 are consistent or the difference is within the allowable range, it means that the clamping is stable, and then Step 5 is started. Conversely, if there is a difference that exceeds the range, it means that the clamping is unstable or the machine malfunctions, and then the machine needs to be stopped for maintenance. This can determine whether the laser etching step in Step 5 is to be performed, and has a machine self-check function.

[0084] Step 5: The laser assembly 200 is started and works with the rotating embossing roller to perform laser etching on the embossing roller. After the preset time, the laser etching is completed, the machine is stopped, the clamps are released, and the embossing roller is removed.

[0085] Its technical advantage lies in the fact that if the values ​​detected by the two pressure sensors 312 are consistent or the difference is within the allowable range during the laser etching process, it means that there is no error in the laser etching process and the product is qualified. Conversely, it means that the product is unqualified. It has the function of detecting the processing quality of the embossing roller.
