Description

Technical Field

[0001] This utility model relates to the technical field of UV light sources, specifically a modular UV light source device. Background Technology

[0002] In industrial production lines, to select and remove defective products, technologies exist that use photosensitive elements to photograph workpieces and then utilize machine vision to determine their quality. This allows for the identification and removal of defective products. Specifically, when photographing a workpiece, it's crucial to place it in a uniform light field, using stable, consistent, and controllable lighting from all directions to minimize shadows and uneven brightness on the workpiece surface. This ensures the photosensitive element obtains a stable and reliable image, thereby improving the recognition rate of the automated optical inspection system.

[0003] In existing production lines, the light source devices used in automatic optical inspection systems mainly consist of LEDs mounted on flexible circuit boards. Flexible circuit boards themselves have high thermal resistance, which makes it difficult to dissipate the heat generated by the LEDs. This results in the inability to use high-power LEDs, and also has an adverse effect on the reliability and lifespan of the LEDs. Furthermore, it makes it inconvenient to replace the LEDs.

Detailed Implementation

[0017] 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.

[0018] See Figures 1-4In this embodiment of the utility model, a modular UV light source device includes a lamp holder 1. An installation ring 2 is provided on the inner side of one end of the lamp holder 1. The installation ring 2 and the lamp holder 1 are fixedly connected by an installation component. A focusing lens 3 is fixedly installed inside the installation ring 2. A reflector cup 8 is fixedly connected to the installation ring 2. A fixing seat 9 is fixedly connected to the bottom of the reflector cup 8. A threaded mounting hole 19 is provided inside the fixing seat 9. A threaded seat 10 is threadedly connected inside the threaded mounting hole 19. An LED bead 11 is fixedly installed inside the threaded seat 10. A terminal 20 is fixedly connected to the tail of the LED bead 11. An installation cylinder 12 is fixedly connected to the bottom of the reflector cup 8. A threaded installation cylinder 12 is fixedly connected to the bottom of the installation cylinder 12. A fixing cylinder 17 is fixedly connected to the lamp holder 1. An installation flange 18 is fixedly connected to the fixing cylinder 17. An installation hole 19 is provided inside the installation flange 18.

[0019] This invention first fixes the lamp holder 1 onto the lamp base by using the mounting flange 18 and mounting hole 19. Then, the reflector cup 8 is screwed into the lamp base by the threaded mounting sleeve 12. The lamp holder 1 and the mounting ring 2 can then be fastened and fixed by the mounting assembly. At the same time, this invention can also screw and fix the lamp bead 11 into the reflector cup 8 by the threaded connection between the threaded mounting hole 19 and the threaded seat 10. This achieves modular installation of the reflector cup 8, the lamp bead 11 and the lamp holder 1, and enables free replacement and assembly of the reflector cup 8, the lamp bead 11 and the lamp holder 1.

[0020] In one instance of this embodiment, please refer to Figures 1-4 The tail of the lamp bead 11 is fixedly connected with a hexagonal screw head 16. The hexagonal screw head 16 facilitates the use of a wrench to unscrew or tighten the lamp bead 11, so as to facilitate quick assembly and disassembly of the lamp bead 11.

[0021] In one instance of this embodiment, please refer to Figures 1-4 The outer wall of the reflector cup 8 is fixedly connected with a plurality of circumferentially distributed heat dissipation fins 14. The heat dissipation fins 14 are provided with a plurality of evenly distributed heat dissipation holes 15. The present invention dissipates heat from the reflector cup 8 by means of heat dissipation fins 14, thereby preventing the reflector cup 8 from overheating. At the same time, the heat dissipation holes 15 can increase the contact area between the heat dissipation fins 14 and the air, thereby accelerating the heat dissipation efficiency of the heat dissipation fins 14.

[0022] In one instance of this embodiment, please refer to Figures 1-4The mounting assembly includes a mounting groove 4 set in the lamp holder 1, a mounting block installed in the mounting groove 4, and a mounting ring 2 fixedly connected to the mounting groove 4. The bottom of the mounting groove 4 is provided with a screw hole 6, and the mounting bolt passes through the mounting block and is threadedly connected to the screw hole 6. The mounting assembly can be fixedly installed into the mounting groove 4 by the threaded connection between the screw hole 6 and the mounting screw 7. Thus, the fixed connection between the mounting groove 4 and the mounting block realizes the relative fixed connection between the mounting ring 2 and the lamp holder 1. Then, when it is necessary to replace the condenser lens 3, the mounting screw 7 can be unscrewed to realize the quick replacement of the condenser lens 3.
