Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, and in particular to a cutting device for processing lamp housings. Background Technology

[0002] The cutting device for lamp housing processing is mainly used for laser cutting of lamp shades. This type of cutting device can achieve efficient and precise cutting of lamp shade materials through high-precision laser technology. It is suitable for lamp housings of various shapes and sizes. Lamp shades are usually made of plastic, glass, metal or other materials. As an advanced processing method, laser cutting can provide high-quality cutting edges, reduce the need for subsequent processing, and maintain the integrity and aesthetics of the material. The core components of this cutting device typically include a laser emitter, a motion control system, a cooling system, and a material support platform. The high-energy laser beam emitted by the laser emitter can instantly heat, melt, or vaporize materials to achieve precise cutting. The motion control system is responsible for precisely controlling the movement speed and direction of the laser head according to the preset cutting path and form, thereby achieving the cutting of the lampshade. The cooling system is used to control the heat generated during the cutting process to prevent the material from deforming or being damaged due to overheating. The advantages of using laser cutting technology are that the cutting process involves almost no physical contact with the material, reducing mechanical stress and the risk of material deformation. In addition, laser cutting can achieve complex cutting shapes and fine cutting details, meeting the requirements of modern lighting design for precision and aesthetics.

[0003] However, existing technologies still present some problems when laser-cutting lampshades. For example, the leftover material after cutting often remains on the surface of the lampshade. These residues not only affect the appearance but may also cause problems in subsequent processing or use. They are difficult to clean and usually require additional steps to clean, increasing the complexity and workload of production. In addition, existing laser cutting devices cannot apply a graphite-based coating to the surface of the lampshade during the laser cutting process. Graphite-based coatings are usually used to improve the wear resistance, heat resistance, and gloss of lampshades, but due to the heat and the influence of the laser beam during the cutting process, this process is currently difficult to perform simultaneously with cutting. Therefore, lighting design and protective coating treatment still need to be carried out separately, resulting in a decrease in production efficiency.

[0004] Chinese Patent Publication No. CN118321750B discloses a cutting device for processing lamp housings. This patent document provides a cutting device for processing lamp housings that allows the lamp housing to rotate, facilitating a wider cutting range for the laser cutting tool. The cutting device includes a mounting frame, support plates, connecting plates, and a placement plate. Support plates are connected to the upper sides of both sides of the mounting frame, and connecting plates are connected between the upper parts of the support plates. The placement plate is rotatably connected to the middle of the mounting frame. This device, by activating a motor on the mounting frame, drives the connecting shaft to rotate on the mounting plate, causing a spur gear to rotate and mesh with a rack, thus rotating the placement plate. This achieves the effect of allowing the lamp housing to rotate, facilitating a wider cutting range for the laser cutting tool.

[0005] Although the device described in the aforementioned patent document can perform laser cutting on the lampshade during use, in actual use, the waste generated after cutting may still adhere to the surface of the lampshade, and it is impossible to add a graphite-based coating to the surface of the lampshade during the laser cutting process, which may cause deformation of the lampshade surface.

A striking component 5 is slidably installed on the inner surfaces of the two limiting components 3. A guide groove 6 is provided in the middle of the upper end of the operating table 1.

[0023] During use, by placing the lampshade housing to be cut on the outer surface of the transmission component 4, and then controlling the transmission component 4, the transmission component 4 can move the lampshade to be cut forward. The transmission component 4 can also provide a guiding and dropping effect for the waste material produced by laser cutting. Meanwhile, the transmission component 4 can also provide power to the striking component 5 during processing, and make the striking component 5 apply a frictional vibration effect to the outer surface of the lampshade during the laser cutting process, shaking off the waste generated during laser cutting and discharging it outward along the transmission component 4. At the same time, the striking component 5 can also coat the surface of the lampshade with a graphite-based coating before laser cutting, thereby improving the absorption rate of the lampshade surface to the laser, reducing the cutting energy loss caused by laser reflection, and reducing the heat-affected zone to avoid whitening and deformation of the lampshade edges.

The pulley 49 is located behind the pulley 48. The discharge assembly 40 is threadedly installed in the middle of the outer surface of the threaded rod 43.

[0026] Furthermore, the outer surfaces of the two pulleys 44, 48, and 49 are all connected by belt drive.

[0027] Furthermore, the two threaded rods 41 are located in the inner cavity of the same side insertion hole 34, and the rear ends of the two threaded rods 41 are rotatably connected to the front side wall of the inner surface of the same side limiting groove 32.

[0028] Furthermore, the discharge assembly 40 includes a threaded block 401. The outer surface of the threaded block 401 is slidably connected to the inner surface of the guide groove 6. The inner surface of the threaded block 401 is threadedly connected to the outer surface of the threaded rod 43. An L-shaped plate 402 is provided at the front end of the threaded block 401. The rear end of the horizontal part of the L-shaped plate 402 is fixedly connected to the front end of the threaded block 401. An inclined truncated cone 403 is attracted to the upper part of the front end of the vertical part of the L-shaped plate 402 by an electromagnet. The middle part of the front end of the vertical part of the L-shaped plate 402 is threadedly connected to the outer surface of the threaded rod 43.

The front end of the inclined truncated cone 403 is attracted to the rear end of the turntable 47 by an electromagnet.

[0029] Furthermore, the striking component 5 includes two sliders 51. Each slider 51 has a threaded hole 52 extending through its rear end at the center of its front end. Each slider 51 is fixedly connected to a second slider 53 at the center of its upper end. Each second slider 53 is fixedly connected to an extension plate 54 at the center of its close proximity. Each extension plate 54 is fixedly connected to an arc-shaped plate 55 at one end close to each other. Each slider 51 is fixedly connected to a laser cutting head 56 at the center of one end close to each other.

[0030] Furthermore, the lower end of the slider 51 on the same side is slidably connected to the bottom wall of the limiting groove 32 on the same side, the threaded hole 52 on the same side is threadedly connected to the outer surface of the threaded rod 41 on the same side, and the outer surface of the slider 53 on the same side is slidably connected to the ends of the two guide plates 33 on the same side that are close to each other.

[0031] Furthermore, a number of rubber columns 551 are fixedly connected to the inner arc surface of the arc plate 55 in a ring array. A rubber ball 552 is fixedly connected to the lower end of each of the rubber columns 551. A spring 553 is fixedly connected to the outer surface of each of the rubber balls 552 on the side that is close to the inner arc surface of the arc plate 55. The springs 553 are located on the outer side of the rubber columns 551 respectively.

[0032] Furthermore, a main board 571 is fixedly connected to the middle of the rear end of each of the two sliders 53. A secondary rod 572 is fixedly connected to the rear end of each main board 571 that is close to each other. A hollow arc-shaped box 573 is fixedly connected to the rear end of each secondary rod 572 that is close to each other. A feeding pipe 574 communicating with the inner cavity of each hollow arc-shaped box 573 is fixedly connected to the upper part of the side of the outer surface of each hollow arc-shaped box 573 that is far apart from each other. Several discharge ports 575 are arranged in a circular array on the inner arc surface of each hollow arc-shaped box 573. Both the middle of the front sidewall and the middle of the inner surface of the rear sidewall are fixedly connected to an arc-shaped material leakage plate 576. The outer arc surfaces of the two arc-shaped material leakage plates 576 are provided with a number of guide holes 577 in a circular array. The inner surfaces of the guide holes 577 on the same side are slidably connected to extrusion columns 578. The outer surfaces of the extrusion columns 578 on the same side and the inner arc surfaces of the arc-shaped material leakage plates 576 on the same side are fixedly connected to springs 570. The ends of the extrusion columns 578 on the same side away from the inner arc surfaces of the arc-shaped material leakage plates 576 on the same side are fixedly connected to extrusion heads 579.

[0033] During use, firstly, by controlling the electromagnet at the front end of the inclined cone 403, the front end of the inclined cone 403 is attracted to the rear end of the turntable 47. Then, the lampshade to be laser-cut is placed on the outside of the inclined cone 403, so that the front side of the inner surface of the lampshade is in contact with the outer surface of the turntable 47. Then, the motor 42 is started, causing the threaded rod 43, which is fixedly connected to its output end through the coupling, to rotate. The inner surface of the threaded block 401 and the inner surface of the vertical part of the L-shaped plate 402 are both in contact with the outer surface of the threaded rod 43. The L-shaped plate 402 and the threaded block 401 are slidably connected to the inner surface of the guide groove 6. Therefore, when the threaded rod 43 rotates, the threaded block 401 and the L-shaped plate 402 can be pushed to move forward on the inner surface of the guide groove 6 at the same time until the front end of the L-shaped plate 402 is in contact with the rear end of the inclined cone 403. At this time, the electromagnetic connection between the front end of the inclined cone 403 and the rear end of the turntable 47 is disconnected, so that the rear end of the inclined cone 403 and the upper part of the front end of the L-shaped plate 402 are attracted and connected by an electromagnet. Then the motor 42 can be restarted, causing the output end of the motor 42 to reverse, which in turn causes the threaded rod 43 to reverse. During the reversal of the threaded rod 43, since the front of the outer surface of the threaded rod 41 on the right and the front of the outer surface of the threaded rod 43 are fixedly connected to the pulley 44, the front of the outer surface of the extension rod 46 and the front of the outer surface of the threaded rod 43 are fixedly connected to the pulley 48, and the front of the outer surface of the threaded rod 41 on the left and the rear of the outer surface of the extension rod 46 are fixedly connected to the pulley 49, and the outer surfaces of the two pulleys 44, the two pulleys 48 and the two pulleys 49 are all connected by belt drive, when the threaded rod 43 rotates, under the drive of the pulleys 44, 48 and 49, the two threaded rods 41 and the extension rod 46 can rotate simultaneously. When the threaded rods 41 on both sides rotate, since the outer surface of the threaded rod 41 on the same side is located in the inner cavity of the insertion hole 34 on the same side, the rear end of the threaded rod 41 on the same side is rotatably connected to the front wall of the inner surface of the limiting groove 32 on the same side, and the threaded hole 52 on the same side is threadedly connected to the outer surface of the threaded rod 41 on the same side, and the lower end of the slider 51 on the same side is slidably connected to the bottom wall of the limiting groove 32 on the same side, when the threaded rods 41 on both sides rotate, the slider 51 can move backward. When the slider 51 moves backward, it can simultaneously drive the slider 53 fixedly connected to its upper end to move backward. The outer surface of the slider 53 on the same side is slidably connected to the... Between the two guide plates 33 on the same side, the slider 2 53 can simultaneously drive the extension plate 54 fixedly connected to it to move backward. The two extension plates 54 are fixedly connected to an arc plate 55. The lower part of the outer surface of several rubber balls 552 is attached to the surface of the lampshade. As the arc plate 55 moves backward, the several rubber balls 552 are fixedly connected to the inner arc surface of the arc plate 55 through the rubber column 551. At the same time, the outer surface of several rubber balls 552 and the inner arc surface of the arc plate 55 are fixedly connected to the spring 1 553. Therefore, the several rubber balls 552 can vibrate by rubbing against the surface of the lampshade. Simultaneously, the laser cutting heads 56 on both sides move backward with the slider 51, while the extension rod 46 rotates with the threaded rod 43, and the turntable 47 rotates with the extension rod 46. This causes the lampshade fitted on the outer surface of the turntable 47 to rotate simultaneously with the turntable 47, thereby enabling the laser cutting heads 56 on both sides to perform laser cutting on the surface of the rotating lampshade. During this process, the sliders 53 on both sides can drive the main board 571 fixedly connected to its rear end to move backward. When the main board 571 moves backward, the auxiliary rods 572 on both sides can drive the inner arc surface of the cavity arc box 573 fixedly connected to it to fit against the surface of the lampshade. Moving backward causes several extrusion heads 579 on the same side to be extruded, and these extrusion heads 579 will drive the corresponding extrusion columns 578 to slide into the guide holes 577 on the same side. The corresponding springs 570 will be compressed and contracted. Then, the graphite-based coating in the inner cavity of the hollow arc-shaped box 573 will flow out through the guide holes 577 and be applied to the surface of the lampshade. By applying a graphite-based coating to the surface of the lampshade, the absorption rate of the lampshade surface to the laser can be improved, the cutting energy loss caused by laser reflection can be reduced, and the heat-affected zone can be reduced to prevent the lampshade edge from whitening and deforming, so as to facilitate subsequent laser cutting processing.

[0034] The waste generated during cutting will be vibrated by several rubber balls 552 and fall into the inner cavity of the lampshade. The inner cavity of the lampshade has an inclined cone 403, and the waste will slide backward and downward with the inclined cone 403, so that the waste does not need to be manually removed from the surface of the lampshade.

[0035] In this design, the guide hole 577 described above is permeable to the graphite-based coating because its surface has several tiny pores, such as... Figure 8 As shown, the small hole does not affect the normal opening position of the guide hole 577. Therefore, the graphite-based coating can flow to the discharge port 575 side through the small hole. The diameter and opening method of the small hole can be adjusted according to the actual use requirements. Therefore, this solution will not elaborate on it in detail.

[0036] Furthermore, the graphite-based coating mentioned above is a conventional material in the prior art. Its main characteristics are extremely high laser absorption rate, reducing laser reflection from the lampshade material, improving energy utilization, strong thermal conductivity and concentrated heat, preventing heat diffusion to non-cutting areas, reducing the heat-affected zone, preventing edge whitening and deformation, high temperature resistance, wear resistance, non-melting and adhesion during cutting, and suitability for mechanical contact scenarios of fully mechanical contour cutting. It is also easy to clean afterward. Therefore, the graphite-based coating mentioned above is a conventional material in the prior art, and its specific usage and material characteristics will not be described in detail in this solution.

[0037] The electromagnet adsorption connection method described above is a conventional connection method in existing technology. It consists of an iron core, an excitation coil, a shell, and an adsorption surface. The iron core is mostly made of soft magnetic material. This type of material can be quickly magnetized to form a strong magnetic field when energized, and quickly demagnetized after the power is turned off, avoiding residual magnetism from affecting the separation operation. The excitation coil is made of enameled copper wire and generates a magnetic field by passing in direct current or alternating current. The number of turns of the coil, the cross-sectional area of ​​the wire, and the magnitude of the input current directly determine the magnetic field strength, which in turn affects the peak value of the adsorption force. When current passes through the excitation coil, the iron core is magnetized and forms a concentrated magnetic field on its adsorption end face. If another magnetic material or a workpiece with a magnetic adsorption surface is brought close at this time, the workpiece will be magnetized by the magnetic field and form opposite magnetic poles. The mutual attraction force, this electromagnetic attraction, overcomes the workpiece's own weight, contact surface friction, and external interference forces, making the two parts fit tightly together. The design of the adsorption surface is crucial to the connection stability. Usually, a flat and smooth surface treatment is used to reduce air gaps. Air gaps are a key factor affecting electromagnetic attraction. Even a small gap can lead to magnetic field leakage and significantly reduce the adsorption force. Therefore, in some applications, positioning pins, grooves, and other structures are set on the adsorption surface to ensure coaxiality and tightness during fitting, while preventing lateral slippage. Therefore, the electromagnet adsorption connection method described above is a conventional connection method in the existing technology. Its specific application connection method can be adjusted according to actual usage requirements. Therefore, this solution will not elaborate on it in detail.

[0038] It should be noted that the specific installation method, circuit connection method, and control method of the motor 42 and the two laser cutting heads 56 used in this invention are all conventional designs, and will not be described in detail here.
