Description

Technical Field

[0001] This utility model relates to the field of AOI light source technology, specifically to an AOI light source for multi-angle detection. Background Technology

[0002] AOI (Automated Optical Inspection) light sources are a crucial component of automated optical inspection equipment. They are primarily used to illuminate the object being inspected, enabling the acquisition of clear images for analysis and judgment. The main function of an AOI light source is to provide sufficient light intensity and uniformity to ensure image quality and accuracy. AOI light sources utilize an array of RGB high-brightness LEDs, illuminating the object at different angles and with different colors. Simply put, an AOI light source is a combination of high-angle and low-angle light. Its most distinctive feature is the combination of high-angle and low-angle light, along with the integration of multiple RGB colors within a single light source. This unique combination allows the AOI light source to illuminate different layers of object details from different angles and with different colors, resulting in a more three-dimensional image.

[0003] As per application number CN201621414030.8, this utility model belongs to the field of AOI (Automated Optical Inspection) technology, and particularly relates to an AOI light source, which consists of a semi-cylindrical first light source and a second light source. A gap is provided between the first and second light sources to facilitate workpiece movement. Both the first and second light sources include a housing and a light-emitting device. The light-emitting device includes a control board and light-emitting elements disposed on the control board. The control board includes a first control board and a second control board. The light-emitting elements include white light-emitting elements, green light-emitting elements, and red light-emitting elements. The first control board is provided with a first control area and a second control area. The white light-emitting element is electrically connected to the first control area, the green light-emitting element is electrically connected to the second control area, and the red light-emitting element is electrically connected to the second control board. On the one hand, this utility model facilitates workpiece inspection in assembly line operations; on the other hand, this utility model realizes the function of individually controlling the light-emitting elements by region and color, thereby achieving the brightness and color required for AOI inspection.

[0004] Similar to the above applications, the following shortcomings still exist:

[0005] When placed, the bottom is in direct contact with the ground, which affects the heat dissipation of the heat sink.

[0006] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a multi-angle detection AOI light source in order to achieve a more practical value. Utility Model Content

[0007] The purpose of this invention is to provide an AOI light source for multi-angle detection to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an AOI light source for multi-angle detection, comprising a protective housing 1 and a support foot. A protective housing 2 is provided at the lower end of the protective housing 1, and a wire interface is installed on the rear outer wall of the protective housing 1. A wire connector is provided at the end of the wire interface. A connection port is opened at the bottom of the inner side of the protective housing 2, and a thickened circuit board is installed on the inner wall of the protective housing 2 and the protective housing 1. Multi-color LED beads are installed on the inner wall of the thickened circuit board, and the multi-color LED beads are distributed in a ring shape about the center of the protective housing 2 and the protective housing 1. A support foot mounting cylinder is fixed at the bottom of the protective housing 2, and the support foot is installed inside the support foot mounting cylinder. The support foot and the support foot mounting cylinder are connected by a snap-fit ​​connection.

[0009] Furthermore, the front outer wall of the second protective shell is provided with a cable tie, and the end of the cable tie is fixed with an elastic strap.

[0010] Furthermore, the elastic straps are symmetrically distributed laterally about the center of the cable tie, and the elastic straps are made of rubber.

[0011] Furthermore, the bottom surface of the second protective shell is equipped with heat sinks, and four sets of heat sinks are provided.

[0012] Furthermore, the heat sink is composed of multiple rectangular strips, and the heat sink is bolted to the second protective shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a protective shell 1 and a protective shell 2 to form a superimposed structure with different diameters, allowing all multi-color LED beads to be laid out for better light emission. Both protective shells 1 and 2 are circular, allowing them to be placed sideways on the ground to adjust the light emission angle of the multi-color LED beads, or placed flat on the ground to create an upward-facing light emission, or suspended to create a downward-facing light emission. This allows for multi-angle adjustment. The elastic straps have excellent elasticity and can be pulled and knotted at will to bind excess wires, preventing tangling and reducing friction between wires. The locking connection between the support foot mounting cylinder and the support foot facilitates positioning of the support foot, preventing the protective shell 2 from directly contacting the ground. This also allows for a gap between the heat sink and the ground, facilitating heat dissipation. Furthermore, the heat sink is evenly distributed on the outer walls of both protective shells 1 and 2, simultaneously dissipating heat and reducing heat accumulation. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example

[0022] like Figures 1-3 As shown, it includes a protective shell 1 and a support foot 8. A protective shell 2 7 is provided at the lower end of the protective shell 1, and a wire interface 2 is installed on the rear outer wall of the protective shell 1. A wire connector 3 is provided at the end of the wire interface 2. A connection port 4 is opened at the bottom of the inner side of the protective shell 2 7. A thickened circuit board 6 is installed on the inner wall of the protective shell 2 7 and the protective shell 1. Multi-color LED beads 5 are installed on the inner wall of the thickened circuit board 6. The multi-color LED beads 5 are distributed in a ring shape about the center of the protective shell 2 7 and the protective shell 1. A support foot mounting cylinder 11 is fixed at the bottom of the protective shell 2 7. The support foot 8 is installed inside the support foot mounting cylinder 11. The support foot 8 and the support foot mounting cylinder 11 are connected by a snap-fit ​​connection.

[0023] In summary: The engaging connection between the support foot mounting cylinder 11 and the support foot 8 facilitates the positioning of the support foot 8, preventing the protective shell 2 7 from directly contacting the ground. The protective shell 1 and the protective shell 2 7 form a stacked structure with different diameters, allowing all the multi-color LED beads 5 to be laid out for better illumination. At the same time, the protective shell 1 and the protective shell 2 7 are round, which can be placed on the ground to adjust the light emission angle of the multi-color LED beads 5, or placed flat on the ground to form an upward direct light emission state, or hung to form a downward direct light emission state, thus allowing for multi-angle adjustment.

[0024] like Figures 1-3 As shown, a cable tie 9 is provided on the front outer wall of the second protective housing 7, and an elastic strap 10 is fixed to the end of the cable tie 9. The elastic straps 10 are symmetrically distributed laterally about the center of the cable tie 9, and the material of the elastic straps 10 is rubber. A heat sink 12 is installed on the bottom surface of the second protective housing 7, and there are four sets of heat sinks 12. The heat sink 12 is composed of multiple rectangular strips, and the heat sink 12 is bolted to the second protective housing 7.

[0025] In summary: the elastic strap 10 has excellent elasticity and can be pulled and knotted at will to bind excess wires, prevent wires from tangling, and reduce friction between wires. The heat sink 12 can maintain a gap with the ground to facilitate heat dissipation. Furthermore, the heat sink 12 is evenly distributed on the outer walls of the second protective shell 7 and the first protective shell 1, dissipating heat simultaneously and reducing heat accumulation.

[0026] Working principle: When this type of multi-angle AOI light source is in use, it first determines the operating principle based on the following: Figures 1-3 Press the support foot 8 to insert the upper end of the support foot 8 into the support foot mounting cylinder 11, so that the support foot 8 can be located at the bottom of the second protective shell 7. The first protective shell 1 and the second protective shell 7 can form a superimposed structure with different diameters, so that all the multi-color LED beads 5 can be laid out for better light emission. At the same time, the first protective shell 1 and the second protective shell 7 are round, so they can be placed on the ground to adjust the light emission angle of the multi-color LED beads 5, or they can be placed flat on the ground to form an upward light emission state, or they can be hung to form a downward light emission state, so that they can be adjusted at multiple angles. The elastic strap 10 has good elasticity and can be pulled and knotted at will to bind excess wires, prevent wire tangling, and reduce friction between wires. The heat sink 12 can leave a gap with the ground to facilitate the heat dissipation of the heat sink 12. The heat sink 12 is evenly distributed on the outer wall of the second protective shell 7 and the first protective shell 1, and heat dissipation is carried out at the same time to reduce heat accumulation.
