Description

Technical Field

[0001] The utility model belongs to the technical field of marking equipment, in particular to a multi-angle laser marking integrated machine. Background Art

[0002] Brand identification is an important part of the product. For cutting tools, laser marking is usually used to engrave the corresponding brand's logo or name on the cutting tool. There are many devices for cutting tool laser marking, such as the Chinese patent document "CN215145736U, a tool laser marking machine for drill bits and milling cutters". In its technical solution, the laser emitter generates laser, which is controlled by the controller to emit. The laser is irradiated on the upper end of the cutting tool for marking. After a cutting tool is marked, the rotating shaft is rotated, and the rotating shaft drives the rotation of the mounting table. The rotation of the mounting table causes the cutting tool to rotate, so that the unprocessed cutting tool is rotated to the lower end of the controller for marking, so that the laser marking has continuity and improves the marking efficiency of the equipment.

[0003] In the prior art, marking equipment can usually only mark one position of a tool. For example, in the above technical solution, "the laser transmitter is connected to the power supply through an electric wire, and the controller is aimed at the upper end of the tool", which means that it can only mark the upper end of the tool. However, according to different customer needs, the marking position and quantity of the tool are different, and laser marking requires the laser to be 90° to the tool surface. However, due to the different shapes of the tools, in order to determine the end face angle of the tool, the tool needs to be placed in a fixed position. At this time, it is impossible to mark multiple surfaces of the tool. Utility Model Content

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Please refer to Figure 1-8 ;

[0030] The laser marking integrated machine described in the utility model has the functions of marking and packaging, and can realize multi-faceted marking of the tool; specifically, it includes a conveying device 11 equipped with a plurality of fixtures 121, and the fixture 121 in this embodiment is provided with a hole 122 for accommodating the end cover, and the side of the conveying device 11 is sequentially installed with a tool storage device 2, an end cover loading device 3 and an outer cover loading device 4; wherein the tool storage device 2 can be a platform, and a position for placing a carrier is provided on the platform, and the tool is placed upright on the carrier, and the tool storage device 2 is correspondingly installed with a laser marking device 51, an angle adjustment device 6 and a transfer device 7;

[0031] During operation, the tool is first taken out from the tool storage device 2 and transferred to the angle adjustment device 6 by the transfer device 7. At the same time, the end cap feeding device 3 places the end cap in the fixture 121 and waits for assembly. It should be noted that the end cap feeding device 3 can output in the form of a vibration plate, and then use a mobile clamp to clamp the end cap and transfer it to the fixture 121. This is a common technical means and will not be described in detail here. Then, the conveying device 11 drives the fixture 121 to rotate so that the end cap reaches the corresponding position for standby.

[0032] Assume that there are two positions on the tool that need to be marked, namely the side face and the end face, which are perpendicular to each other; then the tool is kept in a vertical state so that one of its sides is perpendicular to the laser marking device 51. At this time, the laser marking device 51 emits a laser to mark the side face of the tool. After completion, the tool is flipped 90° by the angle adjustment device 6 so that the end face of the tool corresponds to the laser marking device 51. At this time, the laser marking device 51 marks the end face of the tool. After marking is completed, the tool is reset to a vertical state by the angle adjustment device 6. The transfer device 7 obtains the tool after marking and inserts it into the end cover.

[0033] The conveying device 11 drives the jig 121 to move so that the combined end cap and the tool reach the outer cover loading position, and then the outer cover and the end cap are combined by the outer cover loading device 4 to wrap the tool, and finally the combined product is taken out of the jig 121 and placed in the packaging device 8, and several products are stacked and packaged.

[0034] The above is a complete working process. The following is an explanation of other implementation methods of laser marking.

[0035] Assume that the end face of the tool is a bevel with an inclination angle of 45°. In addition, a visual device 52 is provided on one side of the laser marking device 51 to detect the state of the tool. First, the side of the tool is marked. After completion, the tool is rotated by the angle adjustment device 6. Since the inclination angle of the end face of the tool is 45°, the angle adjustment device 6 is required to drive the tool to rotate 45° so that the end face of the tool is perpendicular to the laser marking device 51. At the same time, the position of the tool is obtained by the visual device 52. Of course, a movable fine-tuning platform can be provided at the bottom of the laser marking device 51 to make fine adjustments according to the visually obtained position to achieve a better marking effect; or the position of the laser marking device 51 can be pre-adjusted. Since the tools are marked in certain batches, the position of the laser marking device 51 can be pre-adjusted to achieve the same technical effect.

[0036] In addition, the rotation angle is adjusted according to the initial placement of the tool. For example, if the end face is facing in the opposite direction, it will require a rotation of 135° to make the end face perpendicular to the laser marking device 51. However, from the perspective of technical solutions, they belong to the same technical solution and should fall within the scope of protection of this application.

[0037] The utility model can realize the multi-faceted marking requirements of the tool by setting the angle adjustment device 6, and can also make corresponding rotation adjustment according to the inclination angle of the marking position. For special-shaped tools, the end face can be kept perpendicular to the laser to achieve the best marking effect.

[0038] One embodiment of the angle adjustment device 6 of the present invention is shown in FIG. Figure 3 , specifically including a fixed seat 61, the fixed seat 61 is provided with at least one clamping position for angle adjustment, the clamping position can rotate between 0°-90°, specifically including a push cylinder 62, the output end of the push cylinder 62 is connected to a rack 63, the rack 63 is meshed with a gear 64, the gear 64 is connected to a rotating shaft 1, the rotating shaft 1 passes through the fixed seat 61 and is connected to a movable block 65, and a clamping claw 66 is installed on the movable block 65; when working, the clamping claw 66 is in a horizontal state, and the vertical The tool is clamped and fixed, and then the laser marking device 51 performs marking operation on the side of the tool. After completion, the rack 63 is driven to move horizontally by pushing the cylinder 62 to rotate the gear 64, and the gear 64 drives the rotating shaft to rotate and drives the movable block 65 to rotate. The clamping claw 66 will rotate synchronously to make the end of the tool correspond to the laser marking device 51. The movement amplitude of the rack 63, that is, the rotation angle of the gear 64, is controlled according to the activity amount of the pushing cylinder, so as to finally achieve the purpose of controlling the rotation angle of the tool.

[0039] Of course, the clamping position can use a servo motor as the rotation control power, which can control the rotation angle more accurately. Again, I will not explain in detail.

[0040] Furthermore, there are two clamping positions which are arranged opposite to each other. A rotating assembly 67 is installed at the bottom of the fixing seat 61. The rotating assembly 67 can drive the two clamping positions to switch, thereby reducing waiting time and improving work efficiency.

[0041] One embodiment of the transfer device 7 of the present invention is shown in FIG. Figure 4 Specifically, it includes a moving component 71, on which a clamping component 72 and a clamping component 73 are installed. The clamping component 72 shuttles between the tool storage device 2 and the clamping position, and the clamping component 73 shuttles between the clamping position and the conveying device 11. By setting the clamping component 72 and the clamping component 73, the movement distance of tool loading and tool transfer is reduced, which can also improve the operating efficiency of the equipment.

[0042] Furthermore, the clamping assembly 73 includes a fixed plate 731, a mounting block 732 is provided at the lower end of the fixed plate 731, a rotating shaft 733 is longitudinally passed through the mounting block 732, a movable clamping block 734 is connected to the end of the rotating shaft 733, a fixed clamping block 735 is provided on the opposite side of the movable clamping block 734, the rotating shaft 733 is fixedly connected to a swing block 736, the swing block 736 is rotatably connected to a connecting block, the connecting block is connected to the output end of the cylinder 737, and the cylinder 737 is fixed on the mounting block 732; specifically, the swing block 736 is driven to rotate by the telescopic action of the cylinder 737, and the rotation of the swing block 736 will drive the rotating shaft 733 to rotate, and finally the movable clamping block 734 and the fixed clamping block 735 are moved away from and close to each other, thereby clamping and releasing the tool.

[0043] One embodiment of the outer cover feeding device 4 of the present invention is as follows: Figure 5 and Figure 6 , specifically including an outer cover conveying component 41, an outer cover straightening component 42, an outer cover transfer component 1 43 and an outer cover transfer component 2 44; since the outer cover is in a rectangular shape with only one end being open, and the direction of the opening is unknown before it is conveyed out, a detection channel 451 is provided at the output end of the outer cover push conveying component, and a detector 452 is provided at the end of the detection channel 451. The detection device is a laser detection. When working, the outer cover is first conveyed from the outer cover conveying component 41 to the detection channel 451, and the opening of the outer cover is detected by the detector 452, and the result is fed back to the control system, and then the outer cover located in the detection channel 451 is transferred to the outer cover straightening component 42 by the outer cover transfer component 1, and the outer cover straightening component 42 first adjusts the shell horizontally according to the information fed back by the system;

[0044] For example, when the detector 452 detects that there is no obstruction, it means that the opening of the shell is close to the detector 452. At this time, the outer cover alignment component 42 needs to rotate the outer cover 180°. When several detectors 452 detect that there is an obstruction, it means that the opening of the shell is facing the other end, which meets the requirements. At this time, the outer cover alignment component 42 does not need to adjust the outer cover horizontally; after completing the above steps, the outer cover alignment component 42 needs to drive the outer cover to stand upright, and finally the outer cover transfer component 2 44 obtains the outer cover and transfers it to the fixture 121 to be mounted on the periphery of the tool and combined with the end cover.

[0045] One embodiment of the housing alignment assembly of the utility model is as follows: Figure 7, specifically including a second fixed seat 421, a rotating member 422 is arranged in the second fixed seat 421, wherein the rotating member 422 can be a combination of a turntable and a rotating cylinder; a pushing channel 423 is arranged on the rotating member 422, and the pushing channel 423 is adapted to the shape of the outer cover, and both ends are openings, and a pushing component 424 and a vertical alignment component 425 are respectively installed at both ends of the pushing channel 423. According to the above embodiment, the state of the outer cover is judged, and it is placed in the pushing channel 423, and the direction of the outer cover is adjusted by the rotating member 422, and it is adjusted to rotate 180° so that the openings at both ends remain corresponding to the pushing component 424 and the vertical alignment component 425. After the angle adjustment is completed, the pushing component 424 extends into the pushing channel 423, and the outer cover is pushed into the vertical alignment component 425; it should be noted that the power component is not used in the figure, and a cylinder can be used as a power source.

[0046] Furthermore, the vertical alignment component 425 includes a swinging portion 4251, and the swinging portion 4251 is provided with a card slot 4252 corresponding to the push. Specifically, the outer cover is pushed into the card slot 4252 by the pushing component 424. In this embodiment, a plurality of pressing blocks 4256 are arranged in the card slot 4252, and a spring is arranged between the pressing block 4256 and the inner wall of the card slot 4252. When the outer cover enters the card slot 4252, the pressing block 4256 is squeezed and the spring is compressed. At the same time, the spring pushes the pressing block 4256 to the inner wall of the card slot 4252. 4256 applies a reverse force to clamp the outer cover, and this principle can be used to adapt to outer covers of different sizes; a gear 2 4253 is provided on one side of the swing part 4251, and the gear 2 4253 is meshed with a rack 2 4254, and the rack 2 4254 is connected to the output end of the cylinder 3 4255. Specifically, the rack 2 4254 is driven to move vertically through the telescopic action of the cylinder 3 4255, thereby causing the gear 2 4253 to rotate, and the rotation of the gear 2 4253 drives the swing block 736 to rotate, so as to realize the vertical alignment of the outer cover.

[0047] It should be noted that the vertical alignment component 425 should also include a housing for rotating the second rack 4254 and the second gear 4253, etc., which is a commonly used technical means and will not be described in detail here.

[0048] In the present utility model embodiment, refer to Figure 6 and Figure 8In order to prevent the end cover from being offset during the assembly process, causing the tool to fall, etc., the fixture 121 needs to fix the end cover. In this embodiment, a hole 122 slightly larger than the end cover is provided in the fixture 121, and a plurality of movable pressure blocks 123 are embedded in the fixture 121. A spring is provided between the movable pressure block 123 and the fixture 121. When the end cover enters the hole 122, the movable pressure block 123 is squeezed and the spring is compressed. At the same time, the spring applies a reverse force to the movable pressure block 123, thereby clamping the end cover. This principle can be used to adapt to end covers of different sizes.

[0049] Since the end cover is clamped and fixed by the fixture 121, external force is required to remove it. In this embodiment, the outer cover transfer component 24 includes a moving component 241, and the moving end of the moving component 241 is provided with a fastening port 442 for fixing the outer cover. A movable pressure block 3 445 and a spring are provided in the fastening port 442, but the pressure applied to the outer cover is greater than the pressure applied to the end cover by the fixture 121, and the fastening port 442 is a slot, which can ensure the vertical state of the outer cover. In order to avoid longitudinal sliding of the outer cover, after the outer cover is combined with the end cover, the outer cover transfer assembly 2 44 moves upward to remove the end cover from the fixture 121 and transfer it to the packaging device 8. A cylinder 443 is installed at the upper end of the fastening port 442. The output end of the cylinder 443 is connected to a push rod 444. The push rod 444 penetrates into the fastening port 442, and the push rod 444 is pushed downward by the cylinder 443 to contact the end of the outer cover, thereby pushing the outer cover out of the fastening port 442.
