Description

Technical Field

[0001] This invention relates to the field of laser marking machine technology, specifically to an intelligent laser marking machine for use on electronic thin films. Background Technology

[0002] Laser marking technology, as an advanced non-contact processing method, has been widely used in numerous fields such as electronics manufacturing, automotive industry, medical devices, and packaging printing due to its significant advantages, including high precision, high speed, permanent marking, and applicability to various materials. In the field of electronic thin film processing and manufacturing, laser marking technology can accurately form clear and durable marks on the surface of thin films, meeting diverse needs such as electronic component identification, product traceability, and functional zoning, and has become an indispensable key process in the production of electronic thin films.

[0003] In the prior art, Chinese patent number CN221389435U discloses a laser marking machine, which mainly consists of a machine body, an adjustment frame, a connecting component, a feeding platform, and a negative pressure vacuum machine. The adjustment frame is used to adjust the height of the laser marking head, and the connecting component can adjust the position of the touch screen. The feeding platform is located directly below the laser marking head and is used to place the workpiece to be marked. The negative pressure vacuum machine is connected inside the feeding platform and uses a vacuum pipe to evacuate the adsorption chamber, causing the adsorption holes above the adsorption chamber to adsorb and fix the workpiece placed on the feeding platform. This is particularly suitable for fixing softer materials such as films or rubber workpieces, preventing wrinkles and warping, and improving operational convenience and work efficiency.

[0004] However, existing technologies still have significant limitations when performing laser marking on electronic films. When double-sided marking is required, current equipment lacks automated flipping functionality, necessitating manual flipping and re-laying of the film multiple times. This manual flipping and feeding process is cumbersome, significantly reducing overall production efficiency. During manual operation, wrinkles may form on the film due to inaccurate placement, leading to laser marking position deviations and affecting marking accuracy and product quality stability. Frequent manual intervention increases operational complexity, demands high operator skills, and carries the risk of equipment downtime or damage due to human error. Summary of the Invention

[0005] To address the aforementioned issues, an intelligent laser marking machine for electronic thin films is provided. By using a flip-over marking device, the overall production efficiency can be significantly improved, while ensuring marking accuracy and product quality stability.

[0009] Preferably, the limiting clamping rod includes a rotating mounting sleeve rotatably mounted on the switching feed channel. The rotating mounting sleeve has a limiting groove inside, and two clamping plates are slidably mounted in the limiting groove. The inner side of the clamping plate has a horizontal clamping surface, and one end of the clamping plate also has a guide angle. An expansion spring is also installed between the two clamping plates. The rotating mounting sleeve is also equipped with a pushing and shrinking device for driving the clamping movement of the two clamping plates. The pushing and shrinking device includes a pushing sleeve slidably mounted inside the rotating mounting sleeve. The pushing sleeve has a pressing rail inside, and the edge of the pressing rail abuts against the guide angle. The pushing and shrinking device also includes a first linear driver installed on the switching feed channel. The output end of the first linear driver is connected to the pushing sleeve.

[0010] Preferably, the tilting traction device includes a first rotating disk and a second rotating disk disposed inside the switching discharge channel. Both the first rotating disk and the second rotating disk are rotatably connected to the switching discharge channel. The second rotating disk is fixedly connected to the rotating clamping device. Multiple storage slots are provided on the outer sides of both the first rotating disk and the second rotating disk. Multiple pushing traction rods are provided on the outer sides of both the first rotating disk and the second rotating disk. The pushing traction rods are slidably connected to the storage slots. The tilting traction device also includes a one-way pushing device that pushes the pushing traction rods to move horizontally.

[0011] Preferably, the bottom of the push-pull traction rod is provided with several suction holes, and the side of the push-pull traction rod is provided with anti-scratch rollers.

[0012] Preferably, the unidirectional pushing device includes a second horizontal screw slide fixedly installed on the side of the switching feeding channel. A horizontal push frame is fixedly installed on the movable end of the second horizontal screw slide. The horizontal push frame is provided with a fixed push rod, and a movable push rod is also rotatably installed on the horizontal push frame.

[0013] Preferably, the limiting feeding device includes a limiting pre-storage plate installed next to the switching feeding channel. The limiting pre-storage plate is used to limit the placement of the electronic film, and an adsorption feeding device is also installed on the limiting pre-storage plate.

[0016] The advantages of this invention compared to the prior art are:

[0017] 1. This invention utilizes a limiting feeding device to horizontally push the electronic film to the switching feeding channel, where a rotating clamping device precisely clamps and fixes it. A first horizontal lead screw slide moves it to the marking area to complete front-side marking. When marking the reverse side is required, the rotating clamping device rotates 180 degrees, and a flipping traction device pulls the electronic film to lay it flat so that the reverse side faces upward. After the switching feeding channel is again limited and fixed, the reverse side is marked. The entire process does not require manual flipping and re-laying of the electronic film multiple times, realizing continuous automatic double-sided marking of the electronic film. This avoids the tedious problem of manual flipping and feeding steps and significantly improves overall production efficiency.

[0018] 2. During the marking process, this invention can flip and lay the electronic film flat to ensure that the electronic film remains stable during marking. This avoids the problem of wrinkles caused by inaccurate placement of the film during manual operation, which leads to laser marking position deviation. It effectively ensures marking accuracy and product quality stability. At the same time, it reduces frequent manual intervention, lowers the complexity of operation, reduces the skill requirements of operators, and avoids the risk of equipment downtime or damage due to human factors, thereby improving the reliability and stability of the production process.

Detailed Implementation

[0031] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0032] See Figures 1 to 10 As shown, an intelligent laser marking machine for electronic films includes a flipping marking device 2 installed on a laser marking machine table 1. The flipping marking device 2 includes a first horizontal lead screw slide 3 fixedly installed on the laser marking machine table 1. A switching feeding channel 4 is fixedly installed on the movable end of the first horizontal lead screw slide 3. The switching feeding channel 4 is horizontally set. A rotating clamping device 5 is horizontally installed inside the switching feeding channel 4. The rotating clamping device 5 is used to clamp and fix the electronic film 8. A flipping traction device 6 is also installed on the rotating clamping device 5. The flipping traction device 6 is used to horizontally traction the electronic film 8. The flipping marking device 2 also includes a limiting feeding device 7 installed on the side of the laser marking machine table 1. The limiting feeding device 7 is used to horizontally place the electronic film 8 into the switching feeding channel 4.

[0033] When laser marking is required on both sides of the electronic film 8, the operator places the electronic film 8 to be marked on the limiting feeding device 7. The limiting feeding device 7 pushes the electronic film 8 horizontally into the switching feeding channel 4. At this time, the clamping end of the rotating clamping device 5 is activated to precisely clamp and fix the electronic film 8, while the switching feeding channel 4 lays the electronic film 8 flat and limits its position, ensuring that the electronic film 8 is facing upwards and remains stable. Subsequently, the first horizontal lead screw slide 3 is activated, and its movable end moves the limited electronic film 8 to the marking area of ​​the laser marking machine 1. The laser marking machine 1 performs laser marking on the front side of the electronic film 8. After the front side of the electronic film 8 is marked, the switching feeding channel 4 releases the limiting of the electronic film 8.

[0034] When marking is required on the reverse side of the electronic film 8, the rotary clamping device 5 and the flipping traction device 6 are activated. The clamping end of the rotary clamping device 5 rotates 180 degrees, causing the electronic film 8 and the flipping traction device 6 to rotate synchronously, resulting in an arc-shaped bend in the electronic film 8. At this time, the traction end of the flipping traction device 6 is positioned between the bend area of ​​the electronic film 8 and the rotary clamping device 5. Next, the traction end of the flipping traction device 6 moves horizontally, causing the electronic film 8 to lie flat and move so that the reverse side of the electronic film 8 faces upward. Subsequently, the feeding channel 4 is switched to again limit and fix the electronic film 8. Afterward, the laser marking machine 1 performs laser marking operations on the reverse side of the electronic film 8.

[0035] After marking is completed on both sides of the electronic film 8, the rotating clamping device 5 and the switching feeding channel 4 release the restrictions on the electronic film 8. At this time, the operator takes out the marked electronic film 8, completing the entire double-sided marking process and realizing continuous automatic double-sided marking of the electronic film 8, effectively improving production efficiency and quality.

[0036] See Figures 1 to 8 As shown, the bottom of the switching feeding channel 4 is provided with a rotating switching groove, which is used to install the rotating clamping device 5. Both sides of the rotating switching groove are provided with adsorption base plates 41, and the side of the rotating switching groove is provided with a traction slide rail 42.

[0037] The adsorption base plate 41 is used to adsorb and fix the laid-out electronic film 8. The traction slide rail 42 provides a moving path for the traction end of the flipping traction device 6. The adsorption base plate 41 is connected to the suction device, which is existing technology and will not be described in detail here.

[0038] When the operator places the electronic film 8 to be marked onto the limiting feeding device 7, the limiting feeding device 7 horizontally pushes the electronic film 8 into the switching feeding channel 4. At this time, the clamping end of the rotating clamping device 5 located in the rotating switching groove is activated to precisely clamp and fix the electronic film 8. At the same time, the adsorption base plate 41 connected to the suction equipment starts to work, generating adsorption force to adsorb and fix the electronic film 8, which is laid flat in the switching feeding channel 4, onto the adsorption base plate 41, ensuring that the electronic film 8 is face up and remains stable, preventing displacement or wrinkling during subsequent movement, and providing stable conditions for front laser marking.

[0039] After the initial limit is completed, the first horizontal lead screw slide 3 starts, and its moving end drives the switching feeding channel 4 and the limited electronic film 8 to move to the marking area of ​​the laser marking machine 1. During this process, the adsorption base plate 41 maintains the adsorption state to ensure the stability of the electronic film 8 during the movement, so that the laser marking machine 1 can accurately perform laser marking operation on the front of the electronic film 8.

[0040] After the front marking of the electronic film 8 is completed, the suction device connected to the adsorption base plate 41 stops working, the adsorption base plate 41 releases the adsorption force on the electronic film 8, and the material discharge channel 4 is switched to complete the limiting task of the front marking stage, in preparation for the back marking of the electronic film 8.

[0041] When marking is required on the reverse side of the electronic film 8, the clamping end of the rotating clamping device 5 rotates 180 degrees, causing the electronic film 8 and the flipping traction device 6 mounted on the traction slide rail 42 to rotate synchronously, causing the electronic film 8 to bend in an arc shape. At this time, the traction end of the flipping traction device 6 is located between the bending area of ​​the electronic film 8 and the rotating clamping device 5. Then, the traction end of the flipping traction device 6 moves horizontally along the traction slide rail 42, causing the electronic film 8 to be laid flat during the movement, so that the reverse side of the electronic film 8 faces upward. Subsequently, the suction base plate 41 restarts the suction function to adsorb and fix the laid-flat electronic film 8, and switches the feeding channel 4 to complete the limiting and fixing of the reverse side of the electronic film 8, so that the laser marking machine 1 can perform laser marking operation on the reverse side of the electronic film 8.

[0042] See Figures 1 to 5 As shown, the rotary clamping device 5 includes a limiting clamping rod 51 rotatably installed inside the rotary switching groove. The rotary clamping device 5 also includes a rotary driver 52 installed on the side of the switching and feeding channel 4. A gear transmission assembly 53 is installed between the output end of the rotary driver 52 and the limiting clamping rod 51.

[0043] After the limiting feeding device 7 horizontally pushes the electronic film 8 into the switching feeding channel 4, the limiting clamping rod 51 initiates a horizontal clamping action. One end of the electronic film 8 enters the limiting clamping rod 51, which precisely clamps and fixes the electronic film 8, ensuring stable positioning of one end. Simultaneously, the adsorption base plate 41 of the switching feeding channel 4 adsorbs and fixes the electronic film 8, ensuring that the entire electronic film 8 faces upwards and remains stable, providing a reliable positioning basis for subsequent front-side laser marking operations.

[0044] After the front marking of the electronic film 8 is completed, the feeding channel 4 is switched to release the adsorption limit on the electronic film 8, and the preparation stage for the reverse marking begins. When it is necessary to mark the reverse side of the electronic film 8, the rotary driver 52 is activated, driving the gear transmission assembly 53 to rotate through its output end. The gear transmission assembly 53 accurately transmits the rotational kinetic energy of the rotary driver 52 to the limiting clamping rod 51, which then rotates 180 degrees. During the rotation, since one end of the electronic film 8 is fixed by the limiting clamping rod 51 and the other end is in a relatively free state, the electronic film 8 will bend in an arc shape as the limiting clamping rod 51 rotates. At this time, the traction end of the flipping traction device 6 is located between the bending area of ​​the electronic film 8 and the limiting clamping rod 51, preparing for the subsequent flipping traction operation.

[0045] See Figures 3 to 6 As shown, the limiting clamping rod 51 includes a rotating mounting sleeve 511 rotatably mounted on the switching feeding channel 4. The rotating mounting sleeve 511 has a limiting groove 5111 inside, and two clamping plates 512 are slidably mounted in the limiting groove 5111. The inner side of the clamping plate 512 has a horizontal clamping surface, and one end of the clamping plate 512 is also provided with a guide angle 5121. An expansion spring 513 is also installed between the two clamping plates 512. The rotating mounting sleeve 511 is also equipped with a pushing and shrinking device for driving the clamping movement of the two clamping plates 512. The pushing and shrinking device includes a pushing sleeve 5141 slidably mounted inside the rotating mounting sleeve 511. The pushing sleeve 5141 has a pressing rail 5142 inside, and the edge of the pressing rail 5142 abuts against the guide angle 5121. The pushing and shrinking device also includes a first linear driver 5143 mounted on the switching feeding channel 4. The output end of the first linear driver 5143 is connected to the pushing sleeve 5141.

[0046] When the limiting feeding device 7 pushes the electronic film 8 horizontally into the switching feeding channel 4, and one end of the electronic film 8 enters between the two clamping plates 512, the limiting clamping rod 51 enters the clamping preparation state.

[0047] When it is necessary to clamp and fix one end of the electronic film 8 between the two clamping plates 512, the push-shrink device is activated. The first linear actuator 5143 is mounted on the switching feed channel 4, and its output end is connected to the push-clamp sleeve 5141, which is slidably mounted inside the rotating mounting sleeve 511. The first linear actuator 5143 pushes the push-clamp sleeve 5141 to move towards the rotating mounting sleeve 511, and the edge of the pressure rail 5142 inside the push-clamp sleeve 5141 abuts against the guide angle 5121 of the two clamping plates 512. As the push-clamp sleeve 5141 continues to move, the edge of the pressure rail 5142 applies a pushing force to the guide angle 5121, causing the two clamping plates 512 to overcome the elastic force of the expansion spring 513 and slide inward in the limiting groove 5111. The horizontal clamping surfaces of the two clamping plates 512 gradually approach each other, finally accurately clamping and fixing one end of the electronic film 8, achieving stable limiting of one end of the electronic film 8.

[0048] When marking is required on the reverse side of the electronic thin film 8, the rotary driver 52 is activated, driving the gear transmission assembly 53 to rotate through its output end. Since the rotating mounting sleeve 511 is connected to the output end of the gear transmission assembly 53, the gear transmission assembly 53 accurately transmits the rotational kinetic energy of the rotary driver 52 to the rotating mounting sleeve 511, thereby driving the limit clamping rod 51 to rotate 180 degrees.

[0049] See Figures 2 to 8 As shown, the flipping traction device 6 includes a first rotating disk 61 and a second rotating disk 62 disposed inside the switching discharge channel 4. Both the first rotating disk 61 and the second rotating disk 62 are rotatably connected to the switching discharge channel 4. The second rotating disk 62 is fixedly connected to the rotating clamping device 5. Multiple storage slots 611 are provided on the outer side of both the first rotating disk 61 and the second rotating disk 62. Multiple pushing traction rods 63 are provided on the outer side of both the first rotating disk 61 and the second rotating disk 62. The pushing traction rods 63 are slidably connected to the storage slots 611. The flipping traction device 6 also includes a one-way pushing device 64 that pushes the pushing traction rods 63 to move horizontally.

[0050] When the front marking of the electronic film 8 is completed and preparation is made for the back marking, the flipping traction device 6 is in an initial standby state, waiting for the rotating clamping device 5 to start the flipping action. After the front marking of the electronic film 8 is completed, the suction base plate 41 of the switching feeding channel 4 releases the suction of the electronic film 8, and the clamping end of the rotating clamping device 5 starts to rotate 180 degrees. Since the second rotating disk 62 is fixedly connected to the rotating clamping device 5, when the rotating clamping device 5 rotates, it will drive the electronic film 8 and the second rotating disk 62 to rotate synchronously. During the rotation, the electronic film 8 is fixed at one end by the rotating clamping device 5, while the other end is in a relatively free state, thus undergoing an arc-shaped bend. At the same time, the rotation of the second rotating disk 62 drives multiple pushing traction rods 63 to rotate. The pushing traction rods 63 remain synchronized with the first rotating disk 61 during the rotation, ensuring the coordination of the movement of each component.

[0051] After the rotating clamping device 5 completes a 180-degree rotation, a storage slot 611 on the first rotating disk 61 and the second rotating disk 62 aligns with the traction rail 42. At this time, the pushing traction rod 63 is positioned between the bending area of ​​the electronic film 8 and the rotating clamping device 5, preparing for subsequent traction of the electronic film 8. This alignment process ensures that the pushing traction rod 63 can accurately act on the electronic film 8 and move along the set path of the traction rail 42.

[0052] The one-way pushing device 64 is activated, causing the pushing traction rod 63 to move horizontally along the traction rail 42. During this horizontal movement, the pushing traction rod 63 contacts the electronic film 8 and applies a pushing force, propelling the electronic film 8 horizontally. Since one end of the electronic film 8 is still fixed by the rotating clamping device 5, under the push of the pushing traction rod 63, the electronic film 8 gradually unfolds and flips over, so that the originally downward-facing reverse side is facing upward. During this process, the traction rail 42 provides a stable movement path for the pushing traction rod 63, ensuring the smoothness and accuracy of the flipping and flattening action of the electronic film 8.

[0053] After the electronic film 8 is flipped and laid flat, the suction function of the adsorption base plates 41 on both sides of the feeding channel 4 is restarted, generating adsorption force to adsorb and fix the laid electronic film 8 onto the adsorption base plates 41. At this time, the electronic film 8 is facing upward and remains stable, providing reliable positioning for the laser marking machine 1 to perform laser marking operation on the reverse side of the electronic film 8.

[0054] See Figures 6 to 9 As shown, the bottom of the push-pull traction rod 63 is provided with several suction holes 631, and the side of the push-pull traction rod 63 is provided with anti-scratch rollers 632.

[0055] After the rotary clamping device 5 completes a 180-degree rotation, a storage slot 611 on the first rotary disk 61 and the second rotary disk 62 docks with the traction slide rail 42. At this time, the pushing traction rod 63 is located between the bending area of ​​the electronic thin film 8 and the rotary clamping device 5.

[0056] The one-way pushing device 64 is activated, pushing the pushing traction rod 63 to move horizontally along the traction rail 42. During the horizontal movement, the anti-scratch roller 632 on the side of the pushing traction rod 63 comes into contact with the electronic film 8, and the anti-scratch roller 632 pushes the bent electronic film 8 to unfold horizontally by rolling. The anti-scratch roller 632 effectively reduces the friction between itself and the electronic film 8, avoiding damage to the electronic film 8 caused by friction and ensuring that the electronic film 8 is not damaged during unfolding. At the same time, the bottom of the pushing traction rod 63 is provided with several suction holes 631, which are connected to a suction device. When the pushing traction rod 63 pushes the electronic film 8 horizontally, the suction device is activated, generating a slight suction force through the suction holes 631, causing the electronic film 8 to slide against the bottom of the pushing traction rod 63. This suction effect effectively ensures that the unfolded electronic film 8 is in a horizontal unfolded state, improving the accuracy and stability of the electronic film 8's flipping and laying.

[0057] See Figures 6 to 8 As shown, the unidirectional pushing device 64 includes a second horizontal screw slide 641 fixedly installed on the side of the switching feeding channel 4. A horizontal push frame 642 is fixedly installed on the movable end of the second horizontal screw slide 641. The horizontal push frame 642 is provided with a fixed push rod 643, and a movable push rod 644 is also rotatably installed on the horizontal push frame 642.

[0058] The movable push rod 644 is unidirectionally rotatably connected to the horizontal push frame 642.

[0059] When the front marking of the electronic thin film 8 is completed and preparation is made for the back marking, the unidirectional pushing device 64 is in the initial standby state. At this time, the movable end of the second horizontal lead screw slide 641 is in the initial position, the horizontal push frame 642 is fixed on the movable end, and the fixed push rod 643 and the movable push rod 644 are installed on the horizontal push frame 642. The pushing traction rod 63 is in the storage slot 611 of the first rotating disk 61 or the second rotating disk 62, waiting for the rotating clamping device 5 to complete a 180-degree rotation and then dock with the traction slide rail 42.

[0060] After the rotating clamping device 5 completes a 180-degree rotation, a storage slot 611 on the first rotating disk 61 and the second rotating disk 62 aligns with the traction rail 42, and the pushing traction rod 63 is positioned between the bending area of ​​the electronic film 8 and the rotating clamping device 5. During this process, one end of the pushing traction rod 63 will contact the movable push rod 644 as it rotates. Since the movable push rod 644 is unidirectionally rotatably connected to the horizontal push frame 642, it will rotate to avoid the rotational pressure of the pushing traction rod 63, allowing the pushing traction rod 63 to pass smoothly. Until the storage slot 611 is fully aligned with the traction rail 42, and the pushing traction rod 63 passes through the movable push rod 644, the movable push rod 644 falls back to its original position due to gravity. At this point, one end of the pushing traction rod 63 is confined between the fixed push rod 643 and the movable push rod 644.

[0061] When it is necessary to push the traction rod 63 horizontally along the traction rail 42 to unfold the electronic film 8, the second horizontal lead screw slide 641 is activated, and its movable end drives the horizontal push frame 642 to move horizontally. During the movement of the horizontal push frame 642, the movable push rod 644 contacts the traction rod 63 and applies a pushing force. Since the traction rod 63 is confined between the fixed push rod 643 and the movable push rod 644, the pushing force of the movable push rod 644 will push the traction rod 63 horizontally along the traction rail 42. During the horizontal movement of the traction rod 63, the anti-scratch roller 632 on its side contacts the electronic film 8, pushing the bent electronic film 8 to unfold horizontally.

[0062] After the electronic thin film 8 has been fully deployed, the second horizontal lead screw slide 641 drives the horizontal pusher 642 to move back to its initial position. During the resetting process, the fixed push rod 643 contacts the pushing traction rod 63 and applies a pushing force, pushing the pushing traction rod 63 to move in the opposite direction along the traction slide rail 42, so that it returns to its initial position.

[0063] See Figures 1 to 2 As shown, the limiting feeding device 7 includes a limiting pre-storage plate 71 installed on the side of the switching feeding channel 4. The limiting pre-storage plate 71 is used to limit the placement of the electronic film 8. An adsorption feeding device 72 is also installed on the limiting pre-storage plate 71.

[0064] Before the double-sided marking operation of the electronic film 8 begins, the staff places the electronic film 8 to be marked horizontally on the limit pre-storage plate 71. The limit pre-storage plate 71 can limit the electronic film 8 in the horizontal direction, ensuring that the electronic film 8 is accurately and stably positioned during placement, and avoiding tilting due to improper placement.

[0065] When the laser marking machine is ready to mark the front of the electronic film 8, the system issues a feeding command, triggering the adsorption and dispensing device 72 to start. The adsorption and dispensing device 72 adsorbs and grabs the electronic film 8 on the limit pre-storage plate 71, and pushes the adsorbed electronic film 8 horizontally from the limit pre-storage plate 71 into the switching dispensing channel 4. During the pushing process, the adsorption and dispensing device 72 maintains a stable adsorption force to ensure that the electronic film 8 will not shift or fall off during the movement, ensuring that the electronic film 8 can enter the switching dispensing channel 4 accurately and smoothly.

[0066] See Figures 2 to 10 As shown, the limit pre-storage plate 71 is fixedly connected to the laser marking machine base 1. The top of the limit pre-storage plate 71 is provided with a horizontal placement area, a thin film sensor is provided on the horizontal placement area, and a blocking strip 711 is provided on the horizontal placement area. A bidirectional horizontal screw slide 712 is fixedly installed at the bottom of the limit pre-storage plate 71, and two limit guide plates 713 are installed at the movable end of the bidirectional horizontal screw slide 712.

[0067] Before the double-sided marking operation of the electronic film 8 begins, the operator places the electronic film 8 to be marked horizontally on the horizontal placement area of ​​the limit pre-storage plate 71. At this time, the front end of the electronic film 8 contacts the blocking strip 711, which effectively restricts further horizontal movement of the electronic film 8, ensuring that the electronic film 8 will not slip out of the horizontal placement area due to excessive placement force. At the same time, the film sensor detects the presence of the electronic film 8 and feeds back the detection signal to the control system of the laser marking machine, indicating that the electronic film 8 has been placed in the designated position, providing a trigger signal for the subsequent automatic feeding operation.

[0068] Two limiting guide plates 713 are located on both sides of the electronic film 8, respectively, to restrict the width of the electronic film 8 and prevent it from shifting left or right during placement. When electronic films 8 of different widths need to be processed, the bidirectional horizontal lead screw slide 712 is activated, and its movable end drives the two limiting guide plates 713 to move towards or away from each other in the horizontal direction, thereby adjusting the distance between the two limiting guide plates 713. Through this adjustment method, the limiting pre-store plate 71 can adapt to electronic films 8 of different widths, improving the adaptability and versatility of the limiting mechanism.

[0069] See Figures 2 to 10 As shown, the adsorption and discharge device 72 includes a third horizontal screw slide 721 fixedly installed on the limit pre-storage plate 71. The movable end of the third horizontal screw slide 721 is equipped with a mounting bracket 722. A horizontal adsorption strip 724 is provided below the mounting bracket 722. A second linear driver 723 is also installed on the mounting bracket 722. The output end of the second linear driver 723 is fixedly connected to the horizontal adsorption strip 724.

[0070] The horizontal adsorption strip 724 is connected to the suction device, giving the horizontal adsorption strip 724 adsorption force.

[0071] During the double-sided marking operation of the electronic film 8, when the electronic film 8, which is limited by the pre-storage plate 71, needs to be moved to the switching feeding channel 4, the second linear actuator 723 is activated, pushing the horizontal adsorption strip 724 downward to make it come into close contact with the electronic film 8, thereby adsorbing and gripping the electronic film 8. Subsequently, the second linear actuator 723 drives the horizontal adsorption strip 724 and the adsorbed electronic film 8 to rise a certain distance, causing the electronic film 8 to detach from the pre-storage plate 71.

[0072] Next, the third horizontal lead screw slide 721 is activated, and its movable end drives the mounting bracket 722 to move horizontally. Since the second linear actuator 723 is fixedly mounted on the mounting bracket 722, and the horizontal adsorption strip 724 is connected to the output end of the second linear actuator 723, the horizontal movement of the mounting bracket 722 will synchronously drive the second linear actuator 723 and the horizontal adsorption strip 724 to move horizontally, thereby enabling the electronic thin film 8 adsorbed on the horizontal adsorption strip 724 to move horizontally.

[0073] During horizontal movement, the horizontal adsorption strip 724 maintains a stable adsorption force, ensuring that the electronic film 8 does not shift or fall off. When the electronic film 8 is accurately pushed to the designated position of the switching and feeding channel 4, the third horizontal lead screw slide 721 stops running, completing the transfer of the electronic film 8 from the limit pre-storage plate 71 to the switching and feeding channel 4.

[0074] Specific working principle:

[0075] When laser marking is required on both sides of the electronic film 8, the operator places the electronic film 8 to be marked on the limiting feeding device 7. The limiting feeding device 7 pushes the electronic film 8 horizontally into the switching feeding channel 4. At this time, the clamping end of the rotating clamping device 5 is activated to precisely clamp and fix the electronic film 8, while the switching feeding channel 4 lays the electronic film 8 flat and limits its position, ensuring that the electronic film 8 is facing upwards and remains stable. Subsequently, the first horizontal lead screw slide 3 is activated, and its movable end moves the limited electronic film 8 to the marking area of ​​the laser marking machine 1. The laser marking machine 1 performs laser marking on the front side of the electronic film 8. After the front side of the electronic film 8 is marked, the switching feeding channel 4 releases the limiting of the electronic film 8.

[0076] When marking is required on the reverse side of the electronic film 8, the rotary clamping device 5 and the flipping traction device 6 are activated. The clamping end of the rotary clamping device 5 rotates 180 degrees, causing the electronic film 8 and the flipping traction device 6 to rotate synchronously, resulting in an arc-shaped bend in the electronic film 8. At this time, the traction end of the flipping traction device 6 is positioned between the bend area of ​​the electronic film 8 and the rotary clamping device 5. Next, the traction end of the flipping traction device 6 moves horizontally, causing the electronic film 8 to lie flat and move so that the reverse side of the electronic film 8 faces upward. Subsequently, the feeding channel 4 is switched to again limit and fix the electronic film 8. Afterward, the laser marking machine 1 performs laser marking operations on the reverse side of the electronic film 8.

[0077] After marking is completed on both sides of the electronic film 8, the rotating clamping device 5 and the switching feeding channel 4 release the restrictions on the electronic film 8. At this time, the operator takes out the marked electronic film 8, completing the entire double-sided marking process and realizing continuous automatic double-sided marking of the electronic film 8, effectively improving production efficiency and quality.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
