Description

Technical Field

[0001] This utility model belongs to the field of LED filament production technology, and in particular relates to a cutting device for LED filament production. Background Technology

[0002] An LED filament is an optical device made of LED chips arranged in a filament shape. Its most prominent feature is that it can emit light from all angles of 360 degrees and achieve high brightness, high luminous efficacy and high color rendering index without the need for auxiliary optical devices.

[0003] In existing LED filament production, long filaments need to be cut into shorter filaments that meet the requirements. Existing cutting equipment has a complex structure, making it inconvenient to quickly adjust and cut into different length specifications during the cutting process. Moreover, as the material roll is continuously unwound, the position of the filament changes constantly, making it inconvenient to adjust the position of the cutter. To address this, we have proposed a cutting device for LED filament production. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a cutting device for LED filament production.

[0005] To achieve the above objectives, this utility model proposes a cutting device for LED filament production, including a worktable. Two material support assemblies are provided on the top of the worktable. A rotating shaft is rotatably mounted on each material support assembly. A filament roll is fixedly sleeved on the outside of the rotating shaft. A guide roller, rotatably connected to the worktable, is provided on one side of each material support assembly. A rubber support plate, fixedly connected to the worktable, is provided on the side of the guide roller away from the material support assembly. A groove is formed on the worktable on the side of the rubber support plate away from the guide roller. A moving assembly is slidably mounted inside the groove. A positioning and cutting assembly is mounted on the moving assembly. This positioning and cutting assembly moves with the moving assembly and performs positioning and cutting of the filament.

[0006] Preferably, the material support assembly includes a vertical plate fixedly connected to the worktable, and two guide rods are movably sleeved inside the vertical plate. A pressure block is fixedly connected to the top of the guide rod, and the pressure block presses the rotating shaft.

[0007] Preferably, the movable component includes a movable seat slidably disposed inside the slide groove, the movable seat having protrusions on both sides, a placement groove on the top of the movable seat, and a magnet slidably disposed inside the placement groove.

[0008] Preferably, the positioning and cutting assembly includes a fixed frame fixedly connected to the top of the movable seat, a push rod motor fixedly connected to the top of the fixed frame, a cutter fixedly connected to the output shaft of the push rod motor, a horizontal plate fixedly connected to one side of the cutter, a lifting rod movably sleeved inside the horizontal plate, a pressure plate fixedly connected to the bottom end of the lifting rod, and a spring sleeved on the outside of the lifting rod connected between the pressure plate and the horizontal plate.

[0009] Preferably, the inner walls on both sides of the slide groove are provided with guide grooves, and the protrusions are slidably disposed in the guide grooves.

[0010] Preferably, the top of the vertical plate is provided with an arc-shaped groove, and the rotating shaft is rotatably disposed in the arc-shaped groove. The top of the vertical plate is provided with two lifting grooves, and the guide rod is movably sleeved in the lifting groove.

[0011] The LED filament cutting device proposed in this utility model can bring the following beneficial effects:

[0012] 1. The position of the positioning and cutting component can be adjusted by moving the component, which makes it easy to adjust according to the position of the filament. It can also quickly adjust the cutting length of different segments. In addition, the filament is pressed and positioned before cutting.

[0013] 2. The rotating shaft and filament roll are lifted by the material support assembly, and the rotating shaft is pressed and positioned to prevent the filament roll from being over-discharged due to inertia during unloading.

[0014] In summary, this solution has a simple structure and a novel design. It not only allows for timely stopping of the filament roll during feeding to prevent overfeeding and helps to straighten the filament, but also facilitates adjustment of the position of the cutter and moving seat, and clamps and positions the filament during cutting. In addition, it allows for quick adjustment of the position of the magnet, thus facilitating cutting into segments of different lengths. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more solutions or examples.

[0028] like Figures 1-5 As shown in the figure, an embodiment of the present invention proposes a cutting device for LED filament production, including a workbench 1. The top of the workbench 1 is provided with two material support components 2. A rotating shaft 3 is rotatably provided on the material support component 2. A filament roll 4 is fixedly sleeved on the outside of the rotating shaft 3. A guide roller 5 is provided on one side of the material support component 2 and is rotatably connected to the workbench 1. A rubber support plate 6 is fixedly connected to the workbench 1 on the side of the guide roller 5 away from the material support component 2. A groove 7 is provided on the side of the rubber support plate 6 away from the guide roller 5 and is opened on the workbench 1. A moving component 8 is slidably provided inside the groove 7. A positioning and cutting component 9 is provided on the moving component 8. The positioning and cutting component 9 moves with the moving component 8 and performs positioning and cutting of the filament.

[0029] like Figure 3 As shown, the material support assembly 2 includes a vertical plate 201 fixedly connected to the workbench 1. Two guide rods 202 are movably sleeved inside the vertical plate 201. A pressure block 203 is fixedly connected to the top of the guide rod 202. The pressure block 203 presses the rotating shaft 3. The pressure block 203 presses the rotating shaft 3 under the action of gravity, increasing the resistance to the rotation of the rotating shaft 3. This prevents the filament roll 4 from being over-discharged due to inertia during unloading.

[0030] like Figure 4 As shown, the movable component 8 includes a movable seat 801 slidably disposed inside the slide groove 7. The movable seat 801 has protrusions 802 on both sides and a placement groove 803 on the top. A magnet 804 is slidably disposed inside the placement groove 803. The magnet 804 slides and adjusts its position within the placement groove 803, and the magnet 804 will be attracted to the movable seat 801 for positioning. This can limit the filament. In addition, the movable seat 801 is provided with scale markings to facilitate the determination of the cutting length.

[0031] like Figure 5As shown, the positioning and cutting assembly 9 includes a fixed frame 901 fixedly connected to the top of the movable base 801. A push rod motor 902 is fixedly connected to the top of the fixed frame 901. A cutter 903 is fixedly connected to the output shaft of the push rod motor 902. A horizontal plate 904 is fixedly connected to one side of the cutter 903. A lifting rod 905 is movably sleeved inside the horizontal plate 904. A pressure plate 906 is fixedly connected to the bottom end of the lifting rod 905. A spring 907 sleeved outside the lifting rod 905 is connected between the pressure plate 906 and the horizontal plate 904. The push rod motor 902 drives the cutter 903 to move downward. The cutter 903 drives the pressure plate 906 to move downward through the spring 907. In this way, the pressure plate 906 moves downward first to press and position the filament, while the cutter 903 continues to move downward and compresses the spring 907, thus completing the cutting of the filament.

[0032] like Figure 2 As shown, guide grooves are provided on the inner walls of both sides of the slide groove 7, and the protrusion 802 is slidably disposed in the guide groove, which guides the protrusion 802.

[0033] like Figure 3 As shown, the top of the vertical plate 201 is provided with an arc-shaped groove, and the rotating shaft 3 is rotatably set in the arc-shaped groove. The top of the vertical plate 201 is provided with two lifting grooves, and the guide rod 202 is movably sleeved in the lifting groove. The guide rod 202 guides the pressure block 203.

[0034] Working principle: The rotating shaft 3 rotates within the arc-shaped groove, allowing the filament roll 4 to unload the filament. The pressure block 203, under gravity, presses the rotating shaft 3 firmly, increasing the resistance to rotation and preventing excessive unloading due to inertia. The filament is then placed into the placement slot 803 on the movable seat 801. Since the length of the movable seat 801 is fixed and pre-measured, there is no need to set graduations on it. The magnet 804 adheres to the movable seat 801 for positioning, thus limiting the filament's movement. This process, combined with the graduations on the movable seat 801, effectively limits the filament's position. The length refers to the length of the filament segment, which facilitates determining the cutting length. The length of the moving seat 801 is the shortest length of the filament used. During cutting, the push rod motor 902 drives the cutter 903 to move downward. The cutter 903 drives the pressure plate 906 to move downward through the spring 907. In this way, the pressure plate 906 moves downward first to press and position the filament, while the cutter 903 continues to move downward and compresses the spring 907, thus completing the cutting of the filament. As the filament is continuously fed, the longitudinal position of the filament will change. At this time, the moving seat 801 is manually adjusted to slide in the slide groove 7, thereby adjusting the cutter 903 to move synchronously, which facilitates better cutting.

Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0036] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
