Description

Technical Field

[0001] This utility model relates to the field of backlight production and processing technology, specifically to an automatic cutting device for backlight production. Background Technology

[0002] A backlight is a light source located behind an LCD display, and its luminous effect directly affects the visual effect of the LCD module. The LCD itself does not emit light; it displays graphics or the result of light modulation. In the production and processing of backlights, large acrylic panels must first be cut to the specified size, a process that requires cutting equipment.

[0003] A search revealed that Chinese Patent Publication No. CN221622357U discloses an acrylic sheet cutting device, comprising a main body plate, a U-shaped plate fixedly mounted at the top center of the main body plate, a movable block slidably mounted at the center of the U-shaped plate, connecting plates fixedly mounted on both the front and rear sides of the movable block, a screw rod threadedly connected to the center of the connecting plate, and a movable knob fixedly mounted at the top of the screw rod. For straight cutting, the screw rod needs to be tightened by the tightening knob and then loosened by the movable knob. At this time, the movable block can move linearly on the surface of the U-shaped plate, completing the straight cutting of the acrylic sheet. For arc cutting, the screw rod needs to be tightened by the movable knob and then loosened by the tightening knob. At this time, the movable block can rotate at the top of the movable block, completing the arc cutting of the acrylic sheet, thus increasing the versatility of the device.

[0004] However, this device also has the following drawbacks:

[0005] The backlight processing requires cutting large acrylic panels into smaller pieces of a specified size. After processing, operators need to manually pick up each acrylic panel one by one for unloading. Acrylic panels are thin and have a smooth surface, making them difficult to grip. In addition, a large number of acrylic panels are cut at a time, resulting in low efficiency for manual unloading and increased labor intensity for operators. This device does not solve this problem.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-3 This utility model provides a technical solution:

[0027] An automatic cutting device for backlight production includes a laser cutting head body 1 and a moving assembly. The moving assembly includes a moving base 2. The laser cutting head body 1 is fixedly installed on one side of the moving base 2. A first lead screw 3 is installed on the bottom of the other side of the moving base 2. The two ends of the first lead screw 3 are rotatably installed on the inner walls of a first support plate 13 and a second support plate 21, respectively. One end of the first lead screw 3 is connected to the output end of a first motor 14. The first motor 14 is fixedly installed on the outer wall of the first support plate 13. Two sets of guide rods 15 are provided above the first lead screw 3. The guide rods 15 are slidably engaged with the top of the other side of the moving base 2. The two ends of 15 are respectively fixedly installed on the inner walls of the first support plate 13 and the second support plate 21. The bottom of the first support plate 13 is installed on the second lead screw 16. The two ends of the second lead screw 16 are rotatably installed on the inner side of the first fixed plate 17. The first fixed plate 17 is fixedly connected to one side of the processing table 4. One end of the second lead screw 16 is connected to the output end of the second motor 18. The second motor 18 is fixedly installed on the outer side of the first fixed plate 17. The bottom of the second support plate 21 is slidably engaged with the slide rod 19. The two ends of the slide rod 19 are fixedly installed on the inner side of the second fixed plate 20. The second fixed plate 20 is fixedly installed on the other side of the processing table 4.

[0028] By setting a first motor 14, the first lead screw 3 can be rotated. The rotating first lead screw 3 can drive the moving seat 2 to move, thereby driving the laser cutting head body 1 to move longitudinally. By setting a second motor 18, the second lead screw 16 can be rotated. The rotating second lead screw 16 can drive the first support plate 13 to move, thereby driving the laser cutting head body 1 and other structures to move laterally. This enables the laser cutting head body 1 to move and cut large acrylic panels, improving processing efficiency.

[0029] It also includes a processing table 4, the top surface of which is provided with a discharge chute 5, and a limit frame 6 is provided above the discharge chute 5, which is fixedly connected to the top surface of the processing table 4.

[0030] By setting the limiting frame 6, large acrylic panels can be limited to prevent them from shifting during the cutting process, thus improving the cutting accuracy.

[0031] It also includes an automatic discharge assembly, which includes a flap 7. The top of the flap 7 is snapped into the discharge trough 5. One side of the flap 7 is rotatably connected to the mounting plate 8 via a rotating shaft. The mounting plate 8 is fixedly installed on the bottom of the processing table 4. The other side of the flap 7 is rotatably engaged with the telescopic end of the electric telescopic rod 10 via a first rotating seat 9. A discharge channel 12 is provided below the other side of the flap 7. The discharge channel 12 is fixedly connected to the bottom inner side of the processing table 4. The other end of the electric telescopic rod 10 is rotatably connected to a second rotating seat 11. One side of the second rotating seat 11 is fixedly installed on the bottom inner side of the processing table 4.

[0032] By setting the flap 7 to engage with the discharge chute 5, the flap 7 can support large acrylic panels, thus ensuring smooth cutting. By setting the electric telescopic rod 10, one end of the flap 7 can be rotated around the other end, so that the cut small acrylic panels slide down the surface of the flap 7 under gravity and are concentrated in the designated position through the discharge channel 12, which greatly improves the discharge efficiency and reduces the labor intensity of the operators.

[0033] In practical use, the device is moved to the designated position, a large acrylic panel is placed in the limiting frame 6, the laser cutting head body 1 is opened, and the laser cutting head body 1 is moved by controlling the moving component to achieve cutting; when the cutting is completed, the telescopic end of the electric telescopic rod 10 is retracted, thereby driving one end of the flip plate 7 to rotate around the other end through the first rotating seat 9, so that the cut small acrylic panel slides down the surface of the flip plate 7 under gravity and is discharged through the discharge channel 12.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
