Description

Technical Field

[0001] This invention relates to the technical field of LED light board cutting, and in particular to a high-efficiency LED light board cutting device and method. Background Technology

[0002] The structure of LED light board 1 produced in the workshop is as follows: Figures 1-2 As shown, its shape is rectangular. The manufacturing process requires that this LED light board 1 be cut into multiple smaller finished light boards 2, i.e., the LED light board 1 is cut into multiple smaller finished light boards 2 using a cutting method. The structure of the finished light board 2 is as follows... Figure 3 As shown, the finished lamp board has a circuit layer, which is used to control the start or stop of the LED lights connected to it.

[0003] The method for cutting this LED light board into multiple small-sized finished light boards 2 in the workshop is as follows:

[0004] S1. A worker takes out an LED light panel 1 and uses the saw blade of a cutting machine to cut it longitudinally into two parts, as shown in the image. Figure 4 The strip light panel 3 shown has the following cutting direction: Figure 1 As shown by the dashed line;

[0005] S2. Workers use a cutting machine to cut a strip light panel 3 into multiple finished light panels 2 along its length, wherein the cutting direction is as follows: Figure 4 As shown by the dashed line, multiple finished light panels 2 are thus produced by cutting a strip light panel 3.

[0006] S3. The worker repeats the operation of step S2 to cut and process multiple finished light panels 2 on another strip light panel 3, thereby finally realizing the cutting of LED light panel 1 into multiple small-sized finished light panels 2.

[0007] S4. By repeating steps S1 to S3 multiple times, workers can continuously cut multiple LED light panels.

[0008] However, although this method can achieve the cutting of LED light board 1, the following technical defects still exist in actual operation:

[0009] I. In steps S2 to S3, the worker needs two processes to cut the two strip light panels 3 into multiple finished light panels 2 respectively. This not only increases the worker's workload, but also increases the cutting time of a single LED light panel 1, thereby reducing the cutting efficiency of a single LED light panel 1.

[0010] II. In step S2, the worker needs to operate the saw blade of the cutting machine multiple times, that is, the saw blade needs to move along... Figure 4The dotted line feed is repeated multiple times to gradually cut the strip light panel 3 into multiple finished light panels 2. This undoubtedly increases the cutting time of a single strip light panel 3, reduces the cutting efficiency of the strip light panel 3, and thus reduces the material cutting efficiency of a single LED light panel 1.

[0011] Therefore, there is an urgent need for a highly efficient cutting device and method that can greatly reduce the workload of workers and greatly improve the cutting efficiency of LED light boards. Summary of the Invention

[0012] The purpose of this invention is to overcome the shortcomings of the prior art and provide a highly efficient LED light board cutting device and method that greatly reduces the labor intensity of workers, greatly improves the efficiency of LED light board cutting, and has a high degree of automation.

[0013] The objective of this invention is achieved through the following technical solution: an efficient cutting device for LED light boards, comprising a worktable and a longitudinal cutting mechanism arranged longitudinally on the worktable surface. The worktable surface is also provided with a left clamping and feeding mechanism and a right clamping and feeding mechanism located on the left and right sides of the longitudinal cutting mechanism. A left transverse cutting mechanism is provided on the left side of the left clamping and feeding mechanism, and a right transverse cutting mechanism is provided on the right side of the right clamping and feeding mechanism.

[0014] The left clamping and feeding mechanism has the same structure as the right clamping and feeding mechanism. The left clamping and feeding mechanism includes a transverse hydraulic slide fixed on the worktable surface and a stepper motor fixed on the top surface of the transverse hydraulic slide moving table I. A turntable is fixed on the output shaft of the stepper motor. A feeding cylinder is fixed on the top surface of the turntable. The piston rod of the feeding cylinder is set to the right, and an L plate is fixed on the extended end.

[0015] A clamping cylinder is fixed on the top surface of the L plate. A longitudinally arranged base is fixed on the top surface of the cylinder barrel of the clamping cylinder. Multiple spaced first U-shaped grooves are opened on the right end face of the base along its length. Positioning pins are fixed on the top surface of the base at its front and rear ends. The piston rod of the clamping cylinder passes through the base, and a longitudinally arranged clamping seat is fixed on its extended end. Multiple spaced second U-shaped grooves are opened on the right end face of the clamping seat along its length. Each second U-shaped groove is located directly above each first U-shaped groove. Through holes are opened on the top surface of the clamping seat at its front and rear ends. Two through holes are respectively opposed to two positioning pins vertically.

[0016] The left transverse cutting mechanism has the same structure as the right transverse cutting mechanism. The left transverse cutting mechanism includes a vertical plate fixed on the workbench, a connecting frame fixed on the right end face of the vertical plate, and a mounting plate fixed on the bottom surface of the connecting frame. A drive motor is fixed on the bottom surface of the mounting plate. A longitudinally arranged main shaft is connected to the output shaft of the drive motor. Multiple transverse cutting saw blades are mounted on the main shaft, which are respectively opposite to the left and right sides of the first U-shaped groove.

[0017] Multiple support legs, which are fixed to the ground, are fixed on the bottom surface of the workbench.

[0018] The longitudinal cutting mechanism includes a pad fixed longitudinally on the worktable and a longitudinal hydraulic slide fixed on the pad. A servo motor is fixed on the top surface of the moving stage II of the longitudinal hydraulic slide. The output shaft of the servo motor is set to the left, and a longitudinal cutting saw blade is installed on the output shaft.

[0019] The diameter of the positioning pin is equal to the diameter of the through hole.

[0020] The left clamping and feeding mechanism and the right clamping and feeding mechanism are symmetrically arranged about the longitudinal cutting saw blade.

[0021] Two bearing seats are fixed on the bottom surface of the mounting plate, and the front and rear ends of the main shaft are respectively rotatably mounted on the two bearing seats.

[0022] The spacing between any two adjacent first U-shaped grooves is equal.

[0023] The high-efficiency cutting device also includes a controller, which is electrically connected to the clamping cylinder, the feed cylinder, the transverse hydraulic slide, the longitudinal hydraulic slide, the stepper motor, the drive motor and the servo motor via signal lines.

[0024] An efficient method for cutting LED light panels includes the following steps:

[0025] S1. The worker takes out an LED light board to be cut. The worker drills two positioning holes on the left edge of the LED light board, ensuring that the diameter of the positioning holes is equal to the diameter of the positioning pins of the left clamping and feeding mechanism, and the longitudinal distance between the two positioning holes is equal to the longitudinal distance between the two positioning pins of the left clamping and feeding mechanism. Then the worker drills two positioning holes on the right edge of the LED light board, ensuring that the longitudinal distance between the two positioning holes is equal to the longitudinal distance between the two positioning pins of the right clamping and feeding mechanism.

[0026] S2. Positioning of LED light board: The worker puts the two positioning holes on the left side of the LED light board into the two positioning pins of the left clamping and feeding mechanism, and at the same time puts the two positioning holes on the right side of the LED light board into the two positioning pins of the right clamping and feeding mechanism, thus realizing the positioning of the LED light board. At this time, the LED light board is just in front of the longitudinal cutting saw blade of the longitudinal cutting mechanism.

[0027] S3. Clamping and fixing of LED light panel: The piston rods of the clamping cylinders of the left clamping and feeding mechanism and the right clamping and feeding mechanism retract downwards simultaneously. The piston rods drive the clamping seat to move downwards, and the clamping seat moves towards the outer edge of the LED light panel. When the piston rods of the two clamping cylinders are fully retracted, the LED light panel can be clamped and fixed. At this time, the left edge of the LED light panel is clamped and fixed between the clamping seat of the left clamping and feeding mechanism and the base, and the right edge of the LED light panel is clamped and fixed between the clamping seat of the right clamping and feeding mechanism and the base. At the same time, the upper ends of the four positioning pins are respectively embedded in the four through holes.

[0028] S4. The specific steps for longitudinal cutting of the LED light board are as follows:

[0029] S41. The servo motor controlling the longitudinal cutting mechanism starts, and the servo motor drives the longitudinal cutting saw blade to rotate;

[0030] S42. The moving table II of the longitudinal hydraulic slide of the longitudinal cutting mechanism moves forward along the length of the longitudinal hydraulic slide. The moving table II drives the servo motor to move forward synchronously, which in turn drives the longitudinal cutting saw blade in the rotating state to move synchronously toward the LED light board. The longitudinal cutting saw blade gradually cuts the LED light board from back to front. When the longitudinal cutting saw blade passes through the LED light board, the LED light board can be cut into two strip light boards.

[0031] S5. Simultaneous cutting of two strip light panels, the specific operation steps are as follows:

[0032] S51. The worker controls the moving table I of the transverse hydraulic slide of the left clamping and feeding mechanism to move to the left along the length of the transverse hydraulic slide. The moving table I drives the drive motor on it to move to the left. The drive motor drives the feed cylinder, the base and the clamping seat to move to the left in sync, thereby driving the strip light panel on the left to move to the left.

[0033] At the same time, the moving stage I of the transverse hydraulic slide that controls the right clamping and feeding mechanism moves to the right along the length of the transverse hydraulic slide. The moving stage I drives the drive motor on it to move to the right. The drive motor drives the feed cylinder, the base and the clamping seat to move to the right in sync, thereby driving the right strip light panel to move to the right.

[0034] S52. When the two strip light panels move away from each other, the stepper motor controlling the left clamping and feeding mechanism is driven. The stepper motor drives the turntable to rotate, and the turntable drives the feed cylinder on it to rotate synchronously. The feed cylinder drives the strip light panel clamped and fixed between the base and the clamping seat to rotate synchronously. When the strip light panel rotates 180°, the controller controls the stepper motor to turn off. At this time, the left strip light panel is facing the various transverse cutting saw blades on the left transverse cutting mechanism.

[0035] At the same time, the stepper motor driving the right clamping and feeding mechanism is controlled. The stepper motor drives the turntable to rotate, and the turntable drives the feed cylinder on it to rotate synchronously. The feed cylinder drives the strip light plate clamped and fixed between the base and the clamping seat to rotate synchronously. When the strip light plate rotates 180°, the controller controls the stepper motor to turn off. At this time, the right strip light plate is facing the various transverse cutting saw blades on the right transverse cutting mechanism.

[0036] S53, the drive motors of the left transverse cutting mechanism and the right transverse cutting mechanism are started, the drive motors drive the main shaft to rotate, and the main shaft drives each transverse cutting saw blade on it to rotate.

[0037] S54. The piston rod of the feed cylinder of the left clamping and feeding mechanism extends to the left. The piston rod drives the base and clamping seat to move to the left, which in turn drives the strip light panel on the left to move towards the direction of each horizontal cutting saw blade of the left horizontal cutting mechanism. Each horizontal cutting saw blade starts to cut the strip light panel from left to right. When the right end of each horizontal cutting saw blade is respectively embedded into the first U-shaped groove, the strip light panel on the left can be cut into multiple finished light panels at one time.

[0038] At the same time, the piston rod of the feed cylinder of the right clamping and feeding mechanism extends to the right, and the piston rod drives the base and clamping seat to move to the right, thereby driving the right strip light panel to move towards the direction of each horizontal cutting saw blade of the right horizontal cutting mechanism. Each horizontal cutting saw blade starts to cut the strip light panel from right to left. When the left end of each horizontal cutting saw blade is respectively embedded into the second U-shaped groove, the right strip light panel can be cut into multiple finished light panels at one time, thus realizing the simultaneous cutting of two strip light panels, and finally completing the cutting of an LED light panel.

[0039] S5. Removal of finished lamp panels: Control the drive motor to turn off, and then control the piston rod of the clamping cylinder to extend upward. The piston rod drives the clamping seat to move upward. When the clamping seat separates from the base, the worker removes each finished lamp panel from the base.

[0040] S7. Workers can continuously cut multiple LED light panels 1 by repeating steps S1 to S6.

[0041] The present invention has the following advantages: it greatly reduces the labor intensity of workers, greatly improves the efficiency of LED light board cutting, and has a high degree of automation. Attached Figure Description

[0073] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0074] like Figures 5-15As shown, an efficient cutting device for LED light panels includes a workbench 4 and a longitudinal cutting mechanism 5 arranged longitudinally on the workbench 4. Multiple support legs are fixed on the bottom surface of the workbench 4 and supported on the ground. The workbench 4 is also provided with a left clamping and feeding mechanism 6 and a right clamping and feeding mechanism 7 located on the left and right sides of the longitudinal cutting mechanism 5. A left transverse cutting mechanism 8 is provided on the left side of the left clamping and feeding mechanism 6, and a right transverse cutting mechanism 9 is provided on the right side of the right clamping and feeding mechanism 7.

[0075] The left clamping and feeding mechanism 6 and the right clamping and feeding mechanism 7 have the same structure. The left clamping and feeding mechanism 6 and the right clamping and feeding mechanism 7 are symmetrically arranged about the longitudinal cutting saw blade 32. The left clamping and feeding mechanism 6 includes a transverse hydraulic slide 10 fixed on the worktable 4 and a stepper motor 12 fixed on the top surface of the moving table I11 of the transverse hydraulic slide 10. A turntable 13 is fixed on the output shaft of the stepper motor 12. A feed cylinder 14 is fixed on the top surface of the turntable 13. The piston rod of the feed cylinder 14 is arranged to the right, and an L plate 15 is fixed on the extension end.

[0076] A clamping cylinder 16 is fixedly mounted on the top surface of the L plate 15. A longitudinally arranged base 17 is fixedly mounted on the top surface of the cylinder barrel of the clamping cylinder 16. A plurality of spaced first U-shaped grooves 18 are opened on the right end face of the base 17 along its length. The distance between each two adjacent first U-shaped grooves 18 is equal. A positioning pin 19 is fixedly mounted on the top surface of the base 17 at its front and rear ends. The diameter of the positioning pin 19 is equal to the diameter of the through hole 22. The piston rod of the clamping cylinder 16 passes through the base 17, and a longitudinally arranged clamping seat 20 is fixedly mounted on its extended end. A plurality of spaced second U-shaped grooves 21 are opened on the right end face of the clamping seat 20 along its length. Each second U-shaped groove 21 is located directly above each first U-shaped groove 18. A through hole 22 is opened on the top surface of the clamping seat 20 at its front and rear ends. The two through holes 22 are respectively opposed to the two positioning pins 19.

[0077] The left transverse cutting mechanism 8 and the right transverse cutting mechanism 9 have the same structure. The left transverse cutting mechanism 8 includes a vertical plate 23 fixed on the workbench 4, a connecting frame fixed on the right end face of the vertical plate 23, and a mounting plate 24 fixed on the bottom surface of the connecting frame. A drive motor 25 is fixed on the bottom surface of the mounting plate 24. A longitudinally arranged main shaft 26 is connected to the output shaft of the drive motor 25. The main shaft 26 is equipped with a plurality of transverse cutting saw blades 27 that are respectively opposed to the left and right sides of the first U-shaped groove 18. Two bearing seats 33 are fixed on the bottom surface of the mounting plate 24. The front and rear ends of the main shaft 26 are rotatably mounted on the two bearing seats 33 respectively.

[0078] The longitudinal cutting mechanism 5 includes a pad 28 fixed longitudinally on the worktable 4 and a longitudinal hydraulic slide 29 fixed on the pad 28. A servo motor 31 is fixed on the top surface of the moving stage II 30 of the longitudinal hydraulic slide 29. The output shaft of the servo motor 31 is set to the left, and a longitudinal cutting saw blade 32 is installed on the output shaft.

[0079] This high-efficiency cutting device also includes a controller, which is electrically connected to the clamping cylinder 16, the feed cylinder 14, the transverse hydraulic slide 10, the longitudinal hydraulic slide 29, the stepper motor 12, the drive motor 25, and the servo motor 31 via signal lines. The controller can control the extension or retraction of the piston rods of the clamping cylinder 16 and the feed cylinder 14, and simultaneously control the start or stop of the transverse hydraulic slide 10, the longitudinal hydraulic slide 29, the stepper motor 12, the drive motor 25, and the servo motor 31, thus featuring a high degree of automation.

[0080] An efficient method for cutting LED light panels includes the following steps:

[0081] S1, the worker takes out a... Figures 1-2 The LED light board 1 to be cut is shown. The worker drills two positioning holes 34 on the left edge of the LED light board 1, ensuring that the diameter of the positioning holes 34 is equal to the diameter of the positioning pins 19 of the left clamping and feeding mechanism 6, and that the longitudinal distance between the two positioning holes 34 is equal to the longitudinal distance between the two positioning pins 19 of the left clamping and feeding mechanism 6. Then, the worker drills two positioning holes 34 on the right edge of the LED light board 1, ensuring that the longitudinal distance between the two positioning holes 34 is equal to the longitudinal distance between the two positioning pins 19 of the right clamping and feeding mechanism 7. The structure of the LED light board 1 with four positioning pins 19 is as follows. Figure 16 As shown;

[0082] S2. Positioning of LED Light Board 1: The worker places the two positioning holes 34 on the left side of LED Light Board 1 onto the two positioning pins 19 of the left clamping and feeding mechanism 6, and simultaneously places the two positioning holes 34 on the right side of LED Light Board 1 onto the two positioning pins 19 of the right clamping and feeding mechanism 7, thereby achieving the positioning of LED Light Board 1. Figures 17-18 As shown, at this time, the LED light panel 1 is just in front of the longitudinal cutting saw blade 32 of the longitudinal cutting mechanism 5;

[0083] S3. Clamping and fixing of LED light panel 1: The piston rods of the clamping cylinders 16 of the left clamping and feeding mechanism 6 and the right clamping and feeding mechanism 7 retract downwards simultaneously. The piston rods drive the clamping seat 20 to move downwards, and the clamping seat 20 moves towards the outer edge of the LED light panel 1. When the piston rods of the two clamping cylinders 16 are fully retracted, the clamping and fixing of the LED light panel 1 is achieved. Figure 19As shown, at this time, the left edge of the LED light board 1 is clamped and fixed between the clamping seat 20 of the left clamping and feeding mechanism 6 and the base 17, while the right edge of the LED light board 1 is clamped and fixed between the clamping seat 20 of the right clamping and feeding mechanism 7 and the base 17. At the same time, the upper ends of the four positioning pins 19 are respectively embedded in the four through holes 22.

[0084] S4, the longitudinal cutting of LED light board 1, the specific operation steps are as follows:

[0085] S41, the servo motor 31 controlling the longitudinal cutting mechanism 5 starts, and the servo motor 31 drives the longitudinal cutting saw blade 32 to rotate;

[0086] S42. The moving table II30 of the longitudinal hydraulic slide 29 controlling the longitudinal cutting mechanism 5 moves forward along the length direction of the longitudinal hydraulic slide 29. The moving table II30 drives the servo motor 31 to move forward synchronously, which in turn drives the rotating longitudinal cutting saw blade 32 to move synchronously towards the LED light panel 1. The longitudinal cutting saw blade 32 gradually cuts the LED light panel 1 from back to front. When the longitudinal cutting saw blade 32 passes through the LED light panel 1, the LED light panel 1 can be cut into two strip light panels 3, such as... Figures 20-21 As shown, the structure of the strip light panel 3 is as follows: Figure 4 As shown;

[0087] S5. Simultaneous cutting of two strip light panels 3, the specific operation steps are as follows:

[0088] S51, the worker controls the moving platform I11 of the transverse hydraulic slide 10 of the left clamping and feeding mechanism 6 to move to the left along the length of the transverse hydraulic slide 10. The moving platform I11 drives the drive motor 25 on it to move to the left. The drive motor 25 drives the feed cylinder 14, the base 17 and the clamping seat 20 to move to the left synchronously, thereby driving the strip light panel 3 on the left side to move to the left. Figure 22 As shown;

[0089] At the same time, the moving table I11 of the transverse hydraulic slide 10 controlling the right clamping and feeding mechanism 7 moves to the right along the length of the transverse hydraulic slide 10. The moving table I11 drives the drive motor 25 on it to move to the right. The drive motor 25 drives the feed cylinder 14, the base 17 and the clamping seat 20 to move to the right in sync, thereby driving the right strip light panel 3 to move to the right.

[0090] S52. When the two strip light panels 3 are far apart, the stepper motor 12 of the left clamping and feeding mechanism 6 is driven, which drives the turntable 13 to rotate. The turntable 13 drives the feed cylinder 14 on it to rotate synchronously. The feed cylinder 14 drives the strip light panel 3 clamped and fixed between the base 17 and the clamping seat 20 to rotate synchronously. When the strip light panel 3 has rotated 180°, the controller controls the stepper motor 12 to turn off. At this time, the left strip light panel 3 is facing the transverse cutting saw blades 27 on the left transverse cutting mechanism 8. Figure 23 As shown;

[0091] Simultaneously, the stepper motor 12 of the right clamping and feeding mechanism 7 is driven, which in turn drives the turntable 13 to rotate. The turntable 13 then drives the feed cylinder 14 on it to rotate synchronously. The feed cylinder 14 drives the strip light plate 3, which is clamped and fixed between the base 17 and the clamping seat 20, to rotate synchronously. When the strip light plate 3 has rotated 180°, the controller controls the stepper motor 12 to shut off. At this time, the right strip light plate 3 is aligned with the transverse cutting saw blades 27 on the right transverse cutting mechanism 9. Figure 13 As shown;

[0092] S53, the drive motor 25 of the left transverse cutting mechanism 8 and the drive motor 25 of the right transverse cutting mechanism 9 are started, the drive motor 25 drives the main shaft 26 to rotate, and the main shaft 26 drives each transverse cutting saw blade 27 on it to rotate.

[0093] S54, the piston rod of the feed cylinder 14 of the left clamping and feeding mechanism 6 extends to the left, driving the base 17 and clamping seat 20 to move to the left, thereby driving the left strip light panel 3 to move towards the directions of the transverse cutting saw blades 27 of the left transverse cutting mechanism 8. Each transverse cutting saw blade 27 starts cutting the strip light panel 3 from left to right, such as... Figures 24-25 As shown, once the right ends of each transverse cutting saw blade 27 are respectively embedded into the first U-shaped groove 18, the strip light panel 3 on the left side can be cut into multiple finished light panels 2 in one operation, such as... Figure 16 As shown, the structure of the cut-out finished lamp panel 2 is as follows: Figure 3 As shown;

[0094] At the same time, the piston rod of the feed cylinder 14 of the right clamping and feeding mechanism 7 extends to the right, and the piston rod drives the base 17 and the clamping seat 20 to move to the right, thereby driving the right strip light panel 3 to move towards each of the transverse cutting saw blades 27 of the right transverse cutting mechanism 9. Each transverse cutting saw blade 27 starts to cut the strip light panel 3 from right to left. When the left end of each transverse cutting saw blade 27 is respectively embedded into the second U-shaped groove 21, the right strip light panel 3 can be cut into multiple finished light panels 2 at one time, thereby realizing the simultaneous cutting of two strip light panels 3, and finally completing the cutting of an LED light panel 1.

[0095] S6. Removal of finished lamp panel 2: Control the drive motor 25 to turn off, and then control the piston rod of the clamping cylinder 16 to extend upward. The piston rod drives the clamping seat 20 to move upward. When the clamping seat 20 separates from the base 17, the worker removes each finished lamp panel 2 from the base 17.

[0096] S7. Workers can continuously cut multiple LED light panels 1 by repeating steps S1 to S6.

[0097] As can be seen from step S5, this cutting device only needs to control the piston rods of the feed cylinders 14 of the left clamping and feeding mechanism 6 and the right clamping and feeding mechanism 7 to extend, so that the two strip light panels 3 can be pushed to the transverse cutting saw blades 27 of the left transverse cutting mechanism 8 and the right transverse cutting mechanism 9 respectively, and then the two strip light panels 3 can be cut into multiple finished light panels 2 at one time. Therefore, compared with the cutting method in the workshop, this cutting device does not require two separate processes to cut the two strip light panels 3, which not only reduces the workload of workers, but also greatly shortens the cutting time of LED light panels 1, thereby greatly improving the cutting efficiency of LED light panels 1.

[0098] Furthermore, the strip light panel 3 is cut into multiple finished light panels 2 in one go by multiple transverse cutting saw blades 27 on the main shaft 26, eliminating the need for workers to use saw blades to gradually cut the strip light panel 3 along its length. Therefore, this cutting device shortens the cutting time of a single strip light panel 3, greatly improves the cutting efficiency of the strip light panel 3, and thus greatly improves the cutting efficiency of a single LED light panel 1.

[0099] Furthermore, as shown in S4-S5, after the LED light panel 1 is longitudinally cut into two strip light panels 3 by the longitudinal cutting saw blade 32 of the longitudinal cutting mechanism 5, the two strip light panels 3 are automatically transferred online to the cutting stations of the left transverse cutting mechanism 8 and the right transverse cutting mechanism 9 by the left clamping and feeding mechanism 6 and the right clamping and feeding mechanism 7, respectively, thus finally producing the finished light panel 2. Therefore, it can be seen that during the entire cutting process, the strip light panel 3 is not individually tooled and fixed, but is automatically cut online, which greatly shortens the cutting time of the strip light panel 3, greatly improves the cutting efficiency of the strip light panel 3, and thus greatly improves the cutting efficiency of a single LED light panel 1.
