Description

Technical Field

[0001] This utility model relates to the field of detection light source equipment technology, and in particular to a modular dual-sided line scan light source. Background Technology

[0002] In online scanning automated optical inspection systems, the illumination angle of the light source has a decisive impact on image quality. For test objects with different materials, different surface morphologies (such as planes and curved surfaces), and different defect types (such as scratches, dents, and protrusions), the light source must be adjusted to a specific "optimal angle" in order to obtain high-contrast defect images.

[0003] Currently, the illumination angles of mainstream line scan light sources are mostly fixed or limitedly adjustable, which has significant drawbacks in practical applications:

[0004] 1. For adjustable light sources, angle adjustment typically requires manually loosening and tightening the fixing devices of each individual module, fine-tuning based on experience, and then locking them back in. For long light sources, this process is time-consuming (often taking tens of minutes to several hours), and it is extremely difficult to ensure that the angles of dozens of modules are strictly consistent. Even slight deviations can lead to uneven illumination, fluctuations in image quality, and seriously affect the accuracy of detection.

[0005] 2. Fixed or coarsely adjustable light sources are difficult to adapt to complex and ever-changing production needs. Frequent replacement of light source modules with different angles leads to high maintenance costs and long production line downtime, resulting in increased costs. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a modular dual-sided line scan light source. This invention can achieve fast, accurate, and consistent overall angle adjustment, which can effectively improve the adaptability of the light source and meet different needs.

[0007] To achieve the above objectives, this utility model provides a modular dual-sided line scan light source, comprising:

[0008] The connector extends along the X-axis to form several mounting positions;

[0009] Several light source modules are provided. Each group of light source modules includes a light source frame, an adjustment component, and several light source units. The light source frame is fixed to the mounting position. The interior of the light source frame forms a mounting cavity with several adjustment slots. The light source units are movably installed inside the mounting cavity, and each light source unit is located on one side of an adjustment slot. The adjustment component is provided with several linkage shafts. Each linkage shaft passes through an adjustment slot and is linked to a light source unit, so that when the adjustment component moves along the adjustment slot, it can drive the light source unit to adjust its angle.

[0010] Furthermore, it includes at least two sets of light source modules, with the light source units and adjustment slots on adjacent sets of light source modules having opposite directions, so that the output light and adjustment directions of the light source units on both sides are opposite.

[0011] Furthermore, the adjusting groove is an arc-shaped groove.

[0012] Furthermore, the light source frame is symmetrically provided with adjustment slots on both sides, and each adjustment slot is equipped with an adjustment component. The adjustment components on both sides are linked with the two sides of the light source unit to realize bidirectional synchronous adjustment of the light source unit.

[0013] Furthermore, the adjustment assembly includes an adjustment link and a locking member. A linkage shaft is provided on one side of the adjustment link, and the adjustment link is linked with the light source unit through the linkage shaft. A connecting through hole is provided on the adjustment link, and the locking member passes through the connecting through hole to position the adjustment link relative to the light source frame.

[0014] Furthermore, the light source frame includes a fixed base, a first wire-out side plate, a second wire-out side plate, a left end plate, and a right end plate. The first wire-out side plate and the second wire-out side plate are respectively fixed to the front and rear sides of the fixed base. The left end plate and the right end plate are respectively disposed on the left and right sides of the fixed base. The left end plate and the right end plate are respectively fixed to the two ends of the first wire-out side plate and the second wire-out side plate. The upper ends of the left end plate and the right end plate abut against the left and right sides of the fixed base.

[0015] Furthermore, the light source frame also includes a connector. Both sides of the first and second outgoing wire side plates are provided with semi-circular grooves. When two adjacent light source modules are installed, the semi-circular grooves of the first and second outgoing wire side plates of the two light source modules are respectively connected to form a complete installation groove. After the connector is installed in the installation groove, it is fixed to the first and second outgoing wire side plates of the two light source modules respectively.

[0016] Furthermore, the bottom of the first and second outgoing side plates are folded back to form a first enclosure and a second enclosure, respectively, and a light outlet is formed between the first enclosure and the second enclosure.

[0017] Furthermore, the light source unit includes a light source adjustment base, a light source circuit board, and a light source lens. The light source circuit board is fixedly connected to the light source adjustment base, and LED beads are integrated on the light source circuit board. The light source lens wraps around the LED beads and is fixedly connected to the light source circuit board.

[0018] Furthermore, a first connecting hole is provided at the front end of both sides of the light source adjustment base. The first connecting hole is rotatably connected to the light source frame through a provided rotating shaft. A second connecting hole is provided at the rear end of both sides of the light source adjustment base away from the first connecting hole. The second connecting hole is connected to the linkage shaft.

[0019] Compared with the closest existing technology, this utility model achieves precise dimming and stable locking of the light source unit from multiple angles by using symmetrically distributed adjustment grooves and linkage adjustment components; the arc-shaped grooves and adjustment rods cooperate to form a controllable rotation path, and the locking element passes through the connecting through hole and is fixed to the light source frame to ensure that the position is firm and reliable after adjustment.

[0020] This invention revolutionizes the cumbersome "individual fine-tuning" process into "one-click synchronization," reducing angle setting time from "hours" to "seconds," significantly improving equipment changeover and process debugging efficiency. A single light source can be adapted to multiple products through rapid angle adjustment, effectively replacing multiple dedicated light sources, thus greatly enhancing the adaptability of this invention and significantly reducing maintenance costs.

[0021] This utility model adopts a modular structure and a coordinated design with its linkage adjustment components, which can achieve high-contrast imaging without blind spots and quickly locate the optimal lighting angle for specific defects; moreover, the pure mechanical linkage structure is robust and durable, has a low failure rate and is easy to maintain, and can effectively control costs.

Detailed Implementation

[0032] The technology of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of this utility model, and not all embodiments. Based on this embodiment of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0035] like Figures 1 to 7 The present invention discloses a modular line scan light source, including a connector 1 and several light source modules 2.

[0036] In this embodiment, the connecting seat 1 is made of a long strip of plate, which extends along the X-axis to form a plurality of mounting positions 11. A plurality of first mounting holes 12 for fixing the light source module 2 can be provided on the mounting positions 11.

[0037] As a preferred option, such as Figure 2 and Figure 3 As shown, in this embodiment, each light source module 2 includes a light source frame 22, an adjustment component 23, and several light source units 21. The light source frame 22 is fixed to the mounting position 11 of the connecting seat 1 by screws or the like. The interior of the light source frame 22 forms a mounting cavity 24, on which several adjustment slots 221 are provided. The adjustment slots 221 are arc-shaped slots. Preferably, arc lines are provided on the outer side of the adjustment slots 221. The arc lines provide a visual reference for angle adjustment, making it easy for users to accurately adjust the tilt angle of the light source unit 21 according to the scale.

[0038] This utility model includes at least two sets of light source modules 2, such as two sets in this embodiment. The light source units 21 and adjustment slots 221 on adjacent sets of light source modules 2 are oriented in opposite directions. Preferably, the center line 26 after the light source modules 2 are spliced ​​together is used as a reference. The light source modules 2 on both sides of the center line 26 are oriented towards the center line 26, so that the output light and adjustment directions of the light source units 21 on both sides are opposite and converge symmetrically at the center line 26, thereby achieving uniform illumination and light intensity superposition of the dual-sided line scan light sources, improving imaging contrast and detection accuracy. Figure 7 In this embodiment, the light source unit 21 on the left faces right, and the light it emits points to the right; the light source unit 21 on the right faces left, and the light it emits points to the left. The light from the two light source units 21 converges at the center line 26. Of course, in some embodiments, multiple light source modules 2 can be arranged with the center line 26 as the axis of symmetry, so that each light source unit 21 and its light emission direction are mirror-distributed, further optimizing the uniformity and coverage of illumination. By adjusting the tilt angle of the slot 221, the pitch angle of the light source unit 21 can be finely adjusted to ensure that the light accurately converges on the target area and reduce stray light interference.

[0039] In this embodiment, as Figures 2 to 4 As shown, the light source frame 22 includes a fixed base 222, a first cable exit side plate 223, a second cable exit side plate 224, a left end plate 225, and a right end plate 226. The first cable exit side plate 223 and the second cable exit side plate 224 are respectively fixed to the front and rear sides of the fixed base 222. The left end plate 225 and the right end plate 226 are respectively disposed on the left and right sides of the fixed base 222. The left end plate 225 and the right end plate 226 are respectively fixed to the two ends of the first cable exit side plate 223 and the second cable exit side plate 224. The upper ends of the left end plate 225 and the right end plate 226 abut against the left and right sides of the fixed base 222, thereby splicing together to form a light source frame 22 with an internal mounting cavity 24.

[0040] Preferably, adjustment slots 221 are symmetrically arranged on both sides of the light source frame 22. That is, adjustment slots 221 are symmetrically arranged in number, direction, shape and position on the first cable outlet side plate 223 and the second cable outlet side plate 224. Each adjustment slot 221 on each side is equipped with an adjustment component 23. The adjustment components 23 on both sides are linked with the two sides of the light source unit 21 to realize bidirectional synchronous adjustment of the light source unit 21.

[0041] Each adjustment assembly 23 includes an adjustment rod 231 and a locking member 232. The locking member 232 can be a hand-tightening screw. A linkage shaft 233 is provided on one side of the adjustment rod 231, through which the adjustment rod 231 is linked to the light source unit 21. A connecting through hole 234 is provided on the adjustment rod 231, and the locking member 232 passes through the connecting through hole 234 to position the adjustment rod 231 relative to the light source frame 22. The locking member 232 cooperates with the adjustment groove 221 to position the adjustment rod 231 on an arc path. By releasing the locking member 232, the adjustment rod 231 slides along the adjustment groove 221, driving the linkage shaft 233 to rotate, thereby adjusting the pitch angle of the light source unit 21. After adjustment, the locking member 232 is tightened again to fix the adjustment rod 231 in the current position, ensuring that the light source unit 21 stably maintains the set angle.

[0042] In order to allow light from the light source unit 21 inside the light source frame 22 to be emitted, this embodiment provides a light outlet 227 at the lower end of the light source frame 22. The light outlet 227 is formed by the gap between the lower ends of the first wire-out side plate 223 and the second wire-out side plate 224 after they are spliced ​​together. Preferably, the bottom of the first wire-out side plate 223 and the second wire-out side plate 224 are folded back to form a first enclosure part 2231 and a second enclosure part 2241, respectively, and the light outlet 227 is formed between the first enclosure part 2231 and the second enclosure part 2241.

[0043] In some embodiments, the first enclosure 2231 and the second enclosure 2241 can be configured as telescopic structures to accommodate different widths of light output. The distance between the first enclosure 2231 and the second enclosure 2241 can be adjusted by telescopic movement, thereby precisely controlling the size of the light outlet 227 and reducing stray light entering the mounting cavity 24. This telescopic structure can be secured with elastic clips or threaded knobs to ensure stable positioning after adjustment. In practical applications, the shape and size of the light outlet 227 are optimized using optical simulation to achieve more uniform light output. Simultaneously, a blackened coating or serrated light-shielding ribs can be provided on the inner sides of the first enclosure 2231 and the second enclosure 2241 to further suppress stray light reflection.

[0044] The light source unit 21 is movably installed inside the mounting cavity 24, such as... Figure 5As shown, each light source unit 21 is located on one side of an adjustment groove 221; the adjustment component 23 is provided with several linkage shafts 233, each linkage shaft 233 passes through an adjustment groove 221 and is linked with a light source unit 21, so that when the adjustment component 23 moves along the adjustment groove 221, it can drive the light source unit 21 to adjust its angle.

[0045] Preferably, the light source unit 21 of this embodiment includes a light source adjustment base 211, a light source circuit board 212, and a light source lens 213. The light source circuit board 212 is fixedly connected to the light source adjustment base 211. An LED bead 214 is integrated on the light source circuit board 212. The light source lens 213 is fixedly connected to the light source circuit board 212 after wrapping around the LED bead 214. A first connection hole 215 is provided at the front ends of both sides of the light source adjustment base 211. The first connection hole 215 is rotatably connected to the light source frame 22 through a provided rotating shaft. A second connection hole 216 is provided at the rear ends of both sides of the light source adjustment base 211 away from the first connection hole 215. The second connection hole 216 is connected to the linkage shaft 233.

[0046] In some implementations... Figure 6 As shown, the light source frame 22 also includes a connector 25. The first outgoing side plate 223 and the second outgoing side plate 224 are provided with semi-arc grooves 2232 on both sides. When two adjacent light source modules 2 are installed, the semi-arc grooves 2232 of the first outgoing side plate 223 and the second outgoing side plate 224 of the two light source modules 2 are respectively connected to form a complete mounting groove. After the connector 25 is installed in the mounting groove, it is fixed to the first outgoing side plate 223 and the second outgoing side plate 224 of the two light source modules 2 respectively.

[0047] The working principle of this utility model is briefly described as follows: The adjusting component 23 drives the linkage shaft 233 to move, which in turn pushes the light source adjusting seat 211 to rotate around the pivot, thereby adjusting the pitch angle of the LED beads 214 and achieving precise control of the light illumination direction. Adjusting slots 221 and adjusting components 23 are provided on both the first and second output side plates 223 and 224, allowing the linkage shaft 23 to slide within the adjusting slots 221, driving the light source units 21 to move synchronously. This enables coordinated adjustment of multiple light sources, with both sides able to adjust synchronously in the same direction, ensuring optical axis consistency. Furthermore, the modular light source module 2 design facilitates expansion and maintenance, allowing for flexible addition or reduction of the number of light source modules 2 according to lighting needs, while also reducing assembly difficulty. The opposite directions of adjacent light source modules 2 ensure that the light output directions of adjacent light sources are focused on the same target area, enhancing lighting concentration and uniformity.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
