Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a phosphor dotting mechanism. Background Technology

[0002] Currently, traditional phosphor dotting processes rely on manual labor or semi-automatic equipment for workpiece dotting, which easily leads to dotting position deviation and affects dotting uniformity. Furthermore, existing technologies require multiple steps for workpiece fixing and dotting component adjustment, resulting in low efficiency and increased defect rates due to human error. Existing assemblies are mostly fixed structures, making it difficult to adapt to workpieces of different shapes or sizes, requiring frequent tooling changes and increasing costs. The phosphor pen mounting structure lacks effective clamping and limiting designs, making it prone to loosening or displacement during high-speed dotting.

[0003] In summary, there is an urgent need to develop a phosphor dotting mechanism with multi-degree-of-freedom collaborative control. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] See Figure 1-8As shown, this utility model provides a technical solution: a phosphor dotting mechanism, including a worktable 1, an X-axis moving module 2, a Y-axis moving module 3, a Z-axis moving module 4, a dotting component 5, and a workpiece assembly component 6. The worktable 1 is equipped with the Y-axis moving module 3, and the workpiece assembly component 6 is mounted on the Y-axis moving module 3. The X-axis moving module 2 is positioned above the workpiece assembly component 6, specifically mounted on a gantry. The X-axis moving module 2 is equipped with the Z-axis moving module 4, and the dotting component 5 is mounted on the Z-axis moving module 4. The X-axis moving modules 2, 3, and 4 are electrically connected to a control system. The control system controls the coordinated movement of the XYZ moving modules, enabling the dotting component 5 to perform dotting operations on the workpiece 7. Through the coordinated control of the XYZ axis moving modules and the control system, the dotting component 5 achieves precise positioning in three-dimensional space, solving the problem of traditional phosphor dotting processes relying on manual labor or semi-automatic equipment, eliminating dotting position offset, and improving dotting uniformity. ‌

[0027] See Figure 2-3 As shown, the dotting assembly 5 includes a dispensing fixture plate 50, a clamping block 51, a stop block 52, and a highlighter 53. The dispensing fixture plate 50 is mounted on the Z-axis moving module 4. The lower part of the dispensing fixture plate 50 is provided with a clamping block 51. The upper surface of the clamping block 51 has a clamping opening 51a. The clamping opening 51a has a shaft-type mounting position 51b. The highlighter 53 is placed inside the shaft-type mounting position 51b. The side of the clamping block 51 has a connecting hole 51c. By setting an adjusting screw, the clamping opening 51a is tightened and the highlighter 53 is clamped by connecting the screw into the connecting hole 51c. The dispensing fixture plate 50 is provided with a stop block 52. The stop block 52 is located above the clamping block 51. The stop block 52 restricts the longitudinal displacement of the highlighter 53. By adjusting the screw of the clamping block 51 and limiting the position of the stop block 52, it is ensured that the highlighter 53 can work continuously without deviation, thus ensuring the stability of the dotting process.

[0028] See Figure 4-6 As shown, the workpiece assembly 6 includes a mounting base 60, an assembly body 61, a linkage 62, a bearing 63, and a drive motor 64. The mounting base 60 is mounted on the X-axis moving module 2. The bearing 63 is located on the front side of the mounting base 60, and the drive motor 64 is located on the rear side. The linkage 62 is located at the output end of the drive motor 64. A rotating shaft 65 is located inside the linkage 62, passing through the bearing 63 and connecting to the assembly body 61. The rotating shaft 65 drives the assembly body 61 to rotate. The drive motor 64 drives the rotating shaft 65 through the linkage 62, which, in conjunction with the bearing 63, enables the assembly body 61 to rotate smoothly, adapting to multi-angle machining requirements.

[0029] See Figure 7-8As shown, the assembly 61 and the rotating shaft 65 are detachably connected. A positioning hole 65a is provided on the end face of the rotating shaft 65 where it connects to the assembly 61. A mating groove 61a, adapted to the end of the rotating shaft 65, is provided on the side of the assembly 61 where it connects to the rotating shaft 65. A fixing hole 61b, corresponding to the positioning hole 65a, is provided inside the assembly 61. A positioning pin is used to connect the assembly 61 to the fixing hole 61b and the positioning hole 65a, thus connecting the assembly 61 and the rotating shaft 65 as a single unit. The detachable assembly 61 is connected to the rotating shaft 65 via the positioning pin. The assembly 61 can be replaced according to actual needs, accommodating workpieces of different sizes, achieving rapid changeover. The modular design of the assembly 61 supports rapid model changeover, meeting the needs of mass production and multi-variety manufacturing.

[0030] The top of assembly 61 is provided with at least two sets of positioning mounting protrusions 61c, which are diagonally distributed. These protrusions secure the working surface of workpiece 7 to assembly 61. The two sets of diagonally distributed protrusions 61c also clamp the locking holes 70 on the working surface of workpiece 7, ensuring no relative displacement between workpiece 7 and assembly 61.

[0031] Working principle: The workpiece 7 is assembled with the assembly 61. Two sets of diagonally distributed positioning assembly protrusions 61c clamp the workpiece 7 onto the working surface of the workpiece 7, ensuring no relative displacement between the workpiece 7 and the assembly 61. The control system inputs the 3D model data of the workpiece 7 and sets the dot coating path. The fluorescent pen 53 is inserted into the shaft mounting position 51b of the clamping block 51, and the adjusting screw is tightened to tighten and fix the fluorescent pen 53 in the clamp 51a, and its longitudinal position is restricted by the stop block 52. The Y-axis moving module 3 drives the workpiece assembly 6 to the working area. The X and Z axis moving modules are linked to adjust the dot coating assembly 5 to above the starting point of the workpiece. The control system synchronously controls the XYZ axis moving modules to move according to the preset path, and the fluorescent pen 53 performs dot coating on the working surface of the workpiece 7 according to the dot coating path. After the dot coating is completed, the dot coating effect of the workpiece 7 is detected, and the next batch of workpieces is then coated.
