After continuous research and design, and after repeated trial production and improvement, the present utility model with real practical value was finally created.
[0043] Please refer to Figure 1-3 The embodiment of the utility model provides a partition detection combined light source, which is cleverly designed and practical. The combined light source mainly includes the following two parts:
[0044] First, there are several light source units 1, which are carefully designed to be connected end to end and arranged in a round-shaped structure. This structural design not only enhances the continuity of the light source, making the lighting more uniform, but also improves the stability of the overall structure.
[0045] Secondly, in order to achieve precise individual control of each light source unit 1, several control lines 2 are introduced. Each control line 2 is connected to a corresponding light source unit 1 and is responsible for controlling its on and off state. This design allows the light source unit 1 that needs to be turned on or off to be flexibly selected according to actual needs, thereby achieving zone lighting and multi-directional lighting.
[0046] It is worth noting that this design can easily meet the lighting needs of various areas of the product. Whether it is a circular arc or a straight edge area, it can get appropriate lighting, thereby improving the accuracy and efficiency of detection. Moreover, with the same light source size, the lighting area of each area light source is larger and more uniform. In addition, since each light source unit 1 can be controlled independently, the brightness of the corresponding light source unit 1 can be adjusted through each control line 2 according to the specific situation, further optimizing the lighting effect.
[0047] Finally, this partition detection combined light source also has the advantages of small size and space saving. Compared with the traditional strip light source combination solution, it is lighter and more flexible and can adapt to more application scenarios.
[0048] To sum up, the partition detection combined light source proposed in the embodiment of the utility model has the advantages of good light source continuity, high lighting demand satisfaction, small size and space saving, and is expected to be widely used in the fields of smart terminal assembly process detection.
[0049] Please refer to Figure 4 , illustratively, in this embodiment, the light source units 1 have eight, namely a first light source unit 11, a second light source unit 12, a third light source unit 13, a fourth light source unit 14, a fifth light source unit 15, a sixth light source unit 16, a seventh light source unit 17 and an eighth light source unit 18;
[0050] The first light source unit 11 and the eighth light source unit 18 are vertically connected to form a first right angle of the round-shaped structure;
[0051] The second light source unit 12 and the third light source unit 13 are vertically connected to form a second right angle of the round-shaped structure;
[0052] The fourth light source unit 14 and the fifth light source unit 15 are vertically connected to form a third right angle of the round-shaped structure;
[0053] The sixth light source unit 16 and the seventh light source unit 17 are vertically connected to form a fourth right angle of the meandering structure.
[0054] It should be noted that eight light source units 1 form eight lighting zones, and lighting in various directions can be achieved by lighting up a combination of different lighting zones to meet the lighting requirements of various areas of the product.
[0055] For example, Figure 5 As shown, for the arc angle areas on the upper left and lower right of the product to be inspected, the second light source unit 12, the third light source unit 13, the sixth light source unit 16 and the seventh light source unit 17 are respectively lit through the corresponding control line 2 to achieve 45° direction illumination tangent to the arc angle;
[0056] For the arc angle areas on the upper right and lower left of the product to be inspected, the fourth light source unit 14, the fifth light source unit 15, the eighth light source unit 18 and the first light source unit 11 are respectively lit through the corresponding control line 2 to achieve 45° direction lighting tangent to the arc angle;
[0057] For the horizontal straight edge areas in the upper middle and lower middle of the product to be inspected, the third light source unit 13, the fourth light source unit 14, the seventh light source unit 17 and the eighth light source unit 18 are respectively lit through the corresponding control line 2 to achieve horizontal lighting parallel to the horizontal straight edge;
[0058] For the vertical straight edge areas in the middle left and middle right of the product to be inspected, the first light source unit 11, the second light source unit 12, the fifth light source unit 15 and the sixth light source unit 16 are respectively lit through the corresponding control line 2 to achieve vertical lighting parallel to the vertical straight edge.
[0059] Please refer again Figure 1 In this embodiment, the design of each light source unit 1 has been carefully considered. They are not simply connected end to end to form a circular structure, but are further adjusted to be inclined toward the central axis of the circular structure. This inclined arrangement brings the following significant advantages:
[0060] First, the tilted light source unit 1 allows the light to be more concentratedly irradiated to the area near the central axis of the round-shaped structure. During the inspection process, this design is particularly suitable for parts of the object that need to be observed or inspected, such as the central area or key components of the product. By enhancing the lighting intensity of these areas, the accuracy and clarity of the inspection can be improved.
[0061] Secondly, the tilted setting also helps reduce shadows and dark areas between light sources. In the traditional light source layout, due to the spacing and angle between light sources, shadows or dark areas often appear in certain areas, affecting the detection effect. The tilted light source unit can better cover these areas, reduce the appearance of shadows and dark areas, and thus provide more comprehensive and uniform lighting.
[0062] In addition, this tilt setting also enhances the flexibility and applicability of the light source. Since the light source units can be controlled independently, combined with the tilt design, the angle and brightness of the light source can be adjusted according to specific detection needs, achieving adaptive lighting for different object shapes and materials.
[0063] Please refer again Figure 1 In this embodiment, a direct plug 3 is installed at one end of the control line 2 away from the corresponding light source unit 1, and a plug 4 is plugged into the direct plug 3.
[0064] It should be noted that this design brings the following significant advantages:
[0065] First, by connecting the power supply through the plug 4, the corresponding light source unit can be easily powered on. Once the plug 4 is inserted into the direct plug 3 and connected to the power supply, the corresponding light source unit 1 will light up immediately and emit the required light. This method is not only easy to operate, but also can ensure the stability and reliability of the power connection.
[0066] Secondly, the combination of the direct plug 3 and the plug 4 makes the whole system more modular and detachable. This means that the light source unit 1 can be easily replaced or adjusted as needed without the need for complex disassembly and reassembly of the whole system. This not only improves the flexibility of the system, but also reduces maintenance costs.
[0067] In addition, this design also takes into account the scalability of the system. If more light source units need to be added in the future, only the corresponding control lines, direct plugs and plugs need to be added, without making large-scale changes to the entire system.
[0068] Although the terms such as light source unit, control line, direct plug, and plug are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
[0069] The utility model provides a partition detection combined light source, which connects a number of light source units end to end into a circular structure, and designs each light source unit to be independently controlled on and off by a control line, so that partition lighting and multi-directional lighting can be achieved, which can meet the lighting needs of various areas of the product. Not only is the continuity of the light source good, but the light source is also small in size, saving space.
[0070] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
