Technical Field

[0001] This utility model relates to the field of flip plate assembly technology, and in particular to a flip plate assembly for a laser engraving device. Background Technology

[0002] Laser marking is a technique that uses a high-energy laser beam to mark or engrave on the surface of an object. It is widely used in industrial manufacturing, jewelry, art and other fields. When marking is required on both sides of a workpiece, the workpiece needs to be flipped over by a flip-plate assembly.

[0003] Existing flip-plate assemblies typically require a fixture to clamp and hold the workpiece before flipping it. However, the fixture applies pressure to the workpiece during clamping, which can easily damage the clamping area, resulting in poor performance. Furthermore, the existing flipping mechanisms are not adjustable, necessitating the replacement of different models when processing workpieces of different sizes, further complicating the process. Therefore, we propose a flip-plate assembly for a laser engraving device. Utility Model Content

[0008] Support plates are installed on both sides of the top of the frame. Each support plate has a telescopic mechanism installed on its side. Each U-shaped frame has a connecting block installed at the top inside. One end of the telescopic mechanism is fixed to the side of the corresponding connecting block.

[0009] The side of each strip-shaped fixing plate is symmetrically provided with two strip-shaped supporting plates, and the side of each strip-shaped supporting plate is connected with the inner surface of the conveying belt.

[0010] The side of each strip-shaped fixing plate is symmetrically provided with two strip-shaped supporting plates, and the side of each strip-shaped supporting plate is connected with the inner surface of the conveying belt.

[0011] Preferably, the side of one of the rotating shafts is provided with an angle sensor.

[0012] Preferably, one end of each strip-shaped fixing plate is provided with a guide plate, and the guide plate is inclined outward.

[0013] Preferably, the distance between the proximal surfaces of the two conveying belts on the same side is the same as the thickness of the workpiece.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0026] Referring to Figures 1-4 A turning plate assembly of a laser marking device, comprising two strip mounting plates 2, both of which are located in the through groove 20 opened at the top of the rack 19, and the laser marking head is located above the two strip mounting plates 2. In actual use, the laser marking head can be used for laser marking on the workpiece placed on the turning plate assembly.

[0027] It should be noted that, as Figure 4 Indicated, the top of the rack 19 is provided with a control cabinet 1, and the control cabinet 1 is provided with a controller inside. The controller is one of a control mainboard, a host computer or a PLC logic controller.

[0028] As Figure 1 And Figure 4 Indicated, the top of the two strip mounting plates 2 is provided with a U-shaped frame 3, and two strip fixed plates 10 are symmetrically arranged between the two U-shaped frames 3. The two ends of the two strip fixed plates 10 are connected by connecting rods. One side of each strip fixed plate 10 is rotatably connected to the corresponding U-shaped frame 3 through a pivot 21. One end of one of the pivots 21 is connected to a first drive motor 9, which is fixed on the U-shaped frame 3. The first drive motor 9 is a brake motor, and the first drive motor 9 is connected to the controller through wires. In actual use, the first drive motor 9 can drive the pivot 21 to rotate, thereby synchronously driving the two strip fixed plates 10 to rotate and completing the turning.

[0029] It should be noted that, as Figure 1As shown in the drawings, the side of one of the rotating shafts 21 is provided with an angle sensor 17 connected to the controller through wires. In actual use, the angle of rotation of the rotating shaft 21 can be detected by the angle sensor 17, and the detection data can be transmitted to the controller. The controller can control the operation of the first driving motor 9 according to the data transmitted by the angle sensor 17, so as to accurately control the rotation angle of the strip-shaped fixed plate 10.

[0030] As shown in the drawings, Figure 1 and Figure 3 each of the strip-shaped mounting plates 2 is provided with a guide groove 13 on the opposite side, and a guide rail 12 is installed at both ends of the through groove 20. The two guide grooves 13 on the same side are slidably sleeved on the corresponding guide rails 12. Through the cooperation of the guide rails 12 and the guide grooves 13, the strip-shaped mounting plates 2 can be limited and kept stable.

[0031] As shown in the drawings, Figure 3 and Figure 4 the top of the rack 19 is provided with a support plate 4 on both sides, and the side of each support plate 4 is provided with a telescopic mechanism 5. The inside top of each U-shaped frame 3 is provided with a connecting block 14, and one end of the telescopic mechanism 5 is fixed to the side of the corresponding connecting block 14. The telescopic mechanism 5 is one of an electric push rod, an air cylinder or a hydraulic rod, and is connected to the controller through wires. In actual use, the strip-shaped mounting plate 2 can be moved by the telescopic mechanism 5, and the distance between the two strip-shaped mounting plates 2 can be adjusted according to the size of the workpiece.

[0032] It should be noted that, as shown in the drawings and Figure 2 each of the strip-shaped fixed plates 10 is provided with a guide plate 11 at one end, and the guide plate 11 is inclined outwardly, forming a trumpet-shaped entrance between the two guide plates 11. As shown in the drawings, Figure 4 when the workpiece is conveyed between the two strip-shaped fixed plates 10 by the belt conveyor, it will be guided and limited by the guide plate 11 to avoid positional misplacement of the workpiece.

[0033] As shown in the drawings, Figure 1 and Figure 2 each of the strip-shaped fixed plates 10 is rotatably connected with two pairs of transmission rollers 7 at both ends of the side, and each pair of transmission rollers 7 is connected by a conveying belt 6. Each of the strip-shaped fixed plates 10 is provided with a second driving motor 18, and the output shaft of each second driving motor 18 is connected with the corresponding transmission roller 7. The second driving motor 18 is connected to the controller through wires. In actual use, the workpiece is placed between the two conveying belts 6, so that the proximal surface of the two conveying belts 6 on the same side is in contact with the surface of the workpiece. Then the second driving motor 18 can drive the transmission roller 7 to rotate, and in turn drive the conveying belt 6 to move, conveying the workpiece.

[0034] It should be noted that, as shown in Figure 3 Each installation groove 16 is internally provided with an infrared sensor 15, and the infrared sensor 15 is located between the two conveying belts 6 on the same side, and is connected with the controller through a wire. In actual use, the position of the workpiece conveyed by the conveying belt 6 can be detected through the infrared sensor 15. When the workpiece is conveyed to the preset position, the infrared sensor 15 transmits the detected data to the controller, and the controller closes the second driving motor 18 to complete the positioning of the workpiece.

[0035] As shown in Figure 1 and Figure 3 Each side of each strip-shaped fixed plate 10 is symmetrically provided with two strip-shaped support plates 8, and each side of each strip-shaped support plate 8 is connected with the inner surface of the conveying belt 6. In actual use, the conveying belt 6 can be supported by the strip-shaped support plate 8, so that the conveying belt 6 remains stable when conveying the workpiece.

[0036] Specifically, in use, the staff controls the controller to control the telescopic mechanism 5 to work, the telescopic mechanism 5 drives the U-shaped frame 3 to move horizontally, adjusts the two U-shaped frames 3 to the preset position, so that the distance between the two strip-shaped fixed plates 10 matches the width of the workpiece, and then the workpiece is conveyed to one end of the conveying belt 6 through the belt conveyor on the rack 19. At the same time, the controller controls the second driving motor 18 to work, and the second driving motor 18 drives the conveying belt 6 to move through the transmission roller 7 to convey the workpiece. When the workpiece is conveyed to the preset position, the infrared sensor 15 transmits the detected data to the controller, and the controller closes the second driving motor 18. Then the laser marking head marks the surface of the workpiece. After the processing is completed, the controller controls the first driving motor 9 to work, and the first driving motor 9 drives the two strip-shaped fixed plates 10 to rotate through the shaft 21. Under the action of the angle sensor 17, the first driving motor 9 can rotate the strip-shaped fixed plate 10 to 180°, so that the other side of the workpiece faces the laser marking head. Then the controller closes the first driving motor 9 and controls the second driving motor 18 to work. The second driving motor 18 conveys the workpiece through the conveying belt 6. Under the action of the infrared sensor 15, the workpiece moves to the preset position. At the same time, the controller closes the second driving motor 18, and the laser marking head marks the other side of the workpiece.

[0037] Further, the distance between the proximal surfaces of the two conveying belts 6 on the same side is the same as the thickness of the workpiece, so that the two conveying belts 6 can fix the workpiece during turning without the need for clamps to clamp, so that the surface of the workpiece is not damaged.

[0038] Further, the rotation angle of the rotating shaft 21 is A, 0°≤A≤180°, so that the second driving motor 18 and the wires connected with the controller of the infrared sensor 15 will not be wound together when the rotating shaft 21 rotates.

[0039] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
