Description

Technical Field

[0001] This utility model relates to the field of machine vision inspection technology, and in particular to a strobe bar light and vision inspection system. Background Technology

[0002] In machine vision inspection systems for new energy batteries, PCB circuit boards, and high-precision 3C electronic products, especially in film inspection, due to limited space or excessively wide products, special industrial cameras—macro cameras—are required for scanning and inspection. Macro cameras have very small working distances, as low as 7mm and typically 15mm. Such confined spaces place high demands on the thickness and brightness of the light source. Therefore, thinner strip light sources (hereinafter referred to as strip lights) are widely used for illumination. To achieve high brightness output, existing strip lights typically employ designs that increase the number of LED chips or enlarge the reflector cup, resulting in a thick and heavy light source module. Excessively thick strip lights are difficult to integrate into inspection stations with limited space. Furthermore, due to the increased number of LED chips or the increased reflective area of ​​the reflector cup, severe heat accumulation occurs inside the strip light. Relying on traditional heat dissipation structures such as through-hole structures or simple fins, the limited contact area with air leads to low heat dissipation efficiency and easily causes the light source temperature to become too high. This not only affects LED lifespan and luminous efficiency stability but may also affect inspection accuracy due to thermal expansion. Utility Model Content

[0003] The purpose of this invention is to provide a strobe light strip that is thin and light-resistant, has high heat dissipation efficiency, and emits bright and uniform light.

[0004] To achieve this objective, the present invention adopts the following technical solution: a strobe bar light, comprising a housing and optical components, wherein the housing has a mounting cavity with a bottom opening; the optical components include a light bar, a focusing rod, and a diffuser plate, wherein the light bar, the focusing rod, and the diffuser plate are sequentially mounted in the mounting cavity along the width direction of the housing, and the diffuser plate is located at the opening of the mounting cavity; wherein, a plurality of heat sinks are protruding from one side of the outer wall of the housing, the heat sinks extend along the length direction of the housing, the plurality of heat sinks are spaced apart along the width direction of the housing, and the housing has a cooling channel located on the side of the light bar away from the diffuser plate and penetrating the housing along the length direction of the housing.

[0005] Preferably, the outer casing includes a base block, a clamping plate, and two connecting blocks. The two ends of the base block are connected to the two ends of the clamping plate through the two connecting blocks. A first positioning platform is provided inside the base block, and a second positioning platform is provided on each of the two connecting blocks on opposite sides. The light strip is clamped between the first positioning platform and the second positioning platform. A plurality of heat sinks are provided on the side wall of the base block, and the cooling channel is located on the side of the first positioning platform away from the light strip.

[0006] Preferably, both the base block and the clamping plate are integrally formed aluminum alloy parts.

[0007] Preferably, the strobe bar light also includes two oppositely arranged connecting frames, each connecting frame having an adjustment mechanism. The connecting blocks at both ends of the housing are respectively connected to the two connecting frames through the adjustment mechanism. The opening of the housing is tilted toward the workpiece to be inspected, and the adjustment mechanism is adapted to adjust the tilt angle of the housing.

[0008] Preferably, the adjustment mechanism includes a connecting part disposed on the connecting frame and two screws. The connecting part is provided with two concentric arc grooves, and the two screws are respectively inserted into the two arc grooves and screwed to the same end of the outer shell.

[0009] Preferably, two adjustment mechanisms are symmetrically arranged along the width direction of the housing, and two housings are provided. Each housing is equipped with the optical component. The two housings are respectively connected to two connecting frames and are symmetrically distributed through the adjustment mechanisms.

[0010] Preferably, along the thickness direction and the width direction of the outer shell, the height of the plurality of heat sinks gradually increases from the edge of the outer shell toward the first positioning platform.

[0011] Preferably, the thickness of the outer casing is less than or equal to 20 mm along the thickness direction, and the maximum height of the heat sink is less than or equal to 10 mm.

[0012] Preferably, the side wall of the housing is provided with a through hole, and the end of the light strip is connected to a standard interface, which passes through the through hole.

[0013] Another objective of this invention is to provide a visual inspection system that combines thinness and high brightness output with strobe light strips.

[0014] To achieve this objective, the present invention adopts the following technical solution: a visual inspection system, including a camera and the aforementioned strobe light strip, wherein the opening of the housing is set toward the focal point of the camera.

[0015] The beneficial effects of this invention are as follows: By incorporating optical components, when the strobe light bar is in operation, the light bar emits light, which is initially focused in the focusing rod and transmitted towards the diffuser plate. The diffuser plate guides the light to converge a second time in the width direction of the housing and diffuses it in the length direction, transforming a discrete point light source into a line light source. This allows the light to be focused into a narrow, bright spot without increasing the number of LEDs or the size of the strobe light bar, effectively reducing the thickness of the housing and facilitating its placement and use. By incorporating heat sinks and cooling channels, coolant is circulated through the cooling channels during use. The heat generated by the light bar is transferred to the heat sink and coolant through the side wall of the housing. This dual cooling system of natural air cooling and water cooling significantly improves the cooling efficiency of the housing, quickly removing heat from the light bar and preventing high temperatures caused by heat buildup inside the housing, thus effectively extending the lifespan of the strobe light bar. The integrated installation of the optical components, heat sink, and cooling channels within the housing results in a thin and light-emitting strobe light bar that is bright and uniform in color, while also offering high heat dissipation efficiency and stable operation.

[0016] This utility model also provides a visual inspection system in which the strobe light used for internal illumination is focused by a light-concentrating rod and a diffuser plate, and is cooled by a heat sink and a cooling channel. It is thin and light-emitting with uniform and bright light, which makes it easy to integrate the visual inspection system into the inspection station with limited space, while ensuring the inspection accuracy.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0024] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0025] Reference Figures 1 to 3As shown, a strobe bar light according to an embodiment of this application includes a housing 1 and an optical component 2. The longitudinal section of the housing 1 is rectangular, and the housing 1 is provided with a mounting cavity 11 with a bottom opening. The optical component 2 includes a light strip 21, a focusing rod 22, and a diffuser plate 23. The light strip 21, the focusing rod 22, and the diffuser plate 23 all extend from one side of the mounting cavity 11 to the other side along the length direction (X direction in the figure). The light strip 21, the focusing rod 22, and the diffuser plate 23 are sequentially installed in the mounting cavity 11 along the width direction of the outer shell 1. The side of the light strip 21 facing the focusing rod 22 is provided with multiple LED beads. The multiple LED beads are arranged in a matrix or linear pattern. The spacing between the LED beads is optimized to ensure the light output brightness per unit area. The focusing rod 22 is made of high-transmittance optical glass or PMMA material, which can concentrate the large-angle divergent light of the LED and improve the light energy utilization rate. The diffuser plate 23 is an optical film with a stretching effect, containing precise light-diffusing particles, which can turn a point light source into a line light source. The diffuser plate 23 is fixed to the opening of the mounting cavity 11 by means of a pressure frame, a slot, or a high-temperature resistant adhesive to shield the focusing rod 22.

[0026] The outer wall of the outer casing 1 has multiple heat sinks 12 protruding from one side. The heat sinks 12 extend along the length of the outer casing 1 and are spaced apart along the width (Y direction in the figure). An air convection channel is formed between two adjacent heat sinks 12. The outer casing 1 has a cooling channel 13, which is located on the side of the light strip 21 away from the diffuser plate 23 and runs through the outer casing 1 along its length. The cooling channel 13 is connected to an external water cooling system or air cooling system to circulate refrigerant or cold air. Common refrigerants such as ethylene glycol and propylene glycol are selected, which will not be described in detail here.

[0027] Understandably, by setting up optical component 2, when the strobe light is working, the light bar 21 emits light, the light is initially converged in the focusing rod 22 and transmitted towards the diffuser plate 23. The diffuser plate 23 guides the light to converge again in the width direction of the housing 1 and diffuse in the length direction of the housing 1, turning the discrete point light source into a line light source. Without increasing the number of LEDs or increasing the volume of the strobe light, the light can be converged into a narrow and bright spot, effectively reducing the thickness of the housing 1 and facilitating its placement and use. By setting up heat sink 12 and cooling channel 13, the cooling channel 13 circulates coolant when the strobe light is in use. The heat generated by the light bar 21 is transferred to the heat sink 12 and coolant through the side wall of the housing 1. Through natural air cooling and water cooling, the cooling efficiency of the housing 1 is greatly improved, the heat of the light bar 21 is quickly removed, and the problem of high temperature of the light source caused by heat accumulation inside the housing 1 is avoided, effectively extending the service life of the strobe light. The optical component 2, heat sink 12 and cooling channel 13 are integrated and installed in the housing 1, making the strobe light thin and light-emitting while producing bright and uniform light.

[0028] Reference Figure 2and Figure 3 As shown, it can be understood that the outer casing 1 includes a base block 14, a clamping plate 15, and two connecting blocks. The base block 14 has a plate 141 opposite to the clamping plate 15. The two ends of the plate 141 are connected to the two ends of the clamping plate 15 through the two connecting blocks. That is, the same end of the plate 141 and the clamping plate 15 are connected by bolts through the same connecting block. The plate 141, the clamping plate 15, and the two connecting blocks define an installation cavity 11. The side of the plate 141 facing the clamping plate 15 has a first positioning platform 142. The two sides of the two connecting blocks have second positioning platforms respectively. The lamp strip 21 is clamped between the first positioning platform 142 and the second positioning platform. That is, the two ends of the lamp strip 21 facing the opening abut against the second positioning platform, and the other side is tightly fitted with the first positioning platform 142. Multiple heat sinks 12 are arranged on the side of the plate 141 away from the clamping plate 15. The cooling channel 13 is located on the side of the first positioning platform 142 away from the lamp strip 21 and passes through the base block 14.

[0029] By setting up the base block 14, clamping plate 15, and connecting block, on the one hand, while ensuring the structural stability of the outer shell 1, the structure of the outer shell 1 can be simplified, making the design and processing of the outer shell 1 more convenient. Simultaneously, it facilitates the sequential fixing and installation of the optical components 2, improving the ease of mounting and dismounting the strobe bar. On the other hand, the second positioning platform of the two connecting blocks presses the heat-generating side of the lamp bar 21 away from the LED beads onto the first positioning platform 142, ensuring sufficient heat exchange area between the lamp bar 21 and the base block 14 for rapid heat exchange. This ensures stable installation of the lamp bar 21 while improving its heat dissipation efficiency. Preferably, in some embodiments, thermally conductive adhesive is coated between the lamp bar 21 and the first positioning platform 142.

[0030] Preferably, both the base block 14 and the clamping plate 15 are integrally formed aluminum alloy parts.

[0031] The base block 14 and the clamping plate 15 are made of lightweight, high-strength and thermally conductive aluminum alloy material. While ensuring the heat dissipation efficiency of the outer shell 1, they can provide rigid support for the mechanical structure of the outer shell 1, ensure the overall structural strength of the strobe light and reduce the overall weight of the strobe light.

[0032] Reference Figure 1 As shown, it can be understood that the strobe bar light also includes two oppositely arranged connecting frames 3. The connecting frames 3 are equipped with an adjustment mechanism. The connecting blocks at both ends of the housing 1 are connected to the two connecting frames 3 through the adjustment mechanism. The opening of the housing 1 is tilted towards the workpiece to be inspected. The adjustment mechanism is adapted to adjust the tilt angle of the housing 1.

[0033] When using stroboscopic strip light, operators do not need to disassemble the outer casing 1 or set up multiple fixed-angle light source combinations. They can rotate or fix the outer casing 1 through the adjustment mechanism to change the light emission direction of the outer casing 1, and simultaneously change the tilt angle between the stroboscopic strip light and the focal point, thereby adjusting the illumination angle. This allows for the detection of workpieces with different reflective effects, expands the application range of stroboscopic strip light, improves its practicality, reduces system complexity, and lowers usage costs.

[0034] Preferably, the adjustment mechanism includes a connecting part 31 disposed on the connecting frame 3 and two screws. The connecting part 31 is provided with two concentric arc grooves 311. The center of the arc grooves 311 is inclined toward one side of the connecting frame 3 in the width direction of the outer shell 1. The two screws are respectively inserted into the two arc grooves 311 and screwed to the same end of the outer shell 1.

[0035] By setting two arc grooves 311 and two screws, when the operator adjusts the angle of the outer shell 1, he / she can loosen the four screws at both ends of the outer shell 1 and adjust the angle around the same focal point along the arc groove 311. This ensures accurate alignment of the strobe bar light while simplifying the overall structure of the adjustment mechanism and making it convenient for the operator to use.

[0036] It should be noted that, in this application, the angle between the light-emitting direction of the outer shell 1 and the plane where the workpiece to be inspected is located (usually parallel to the horizontal plane) is the tilt angle of the outer shell 1. The central angle of the arc groove 311 is greater than 50°, and the angle adjustment range of the outer shell 1 is 20° to 50° (including the endpoint). When inspecting workpieces with highly reflective surfaces, the operator can choose a smaller angle (e.g., 20°) to enhance defect contrast; when inspecting workpieces with rough surfaces or diffuse reflective objects, the operator can choose a larger angle (e.g., 50°) to achieve uniform coverage. In addition, scale markings 312 are provided on the opposite sides of the two connecting parts. The scale markings 312 include scale lines set on the opposite sides of the two arc grooves 311 and angle markings located between the two arc grooves 311. The operator can accurately control the tilt angle of the outer shell 1 through the angle markings, thereby improving the controllability of the strobe light and the accuracy of the inspection results.

[0037] Furthermore, there are two adjustment mechanisms, which are symmetrically distributed on both sides of the connecting frame 3. There are two outer shells 1, and each outer shell 1 is equipped with an optical component 2. The two outer shells 1 are respectively connected to the two connecting frames 3 and are symmetrically distributed through the adjustment mechanisms.

[0038] With the outer casing 1 tilted, when a single strobe bar illuminates the workpiece, the side of the workpiece closer to casing 1 is relatively darker than the other side. By setting two casings 1 to emit light synchronously, the workpiece to be inspected can be completely covered, ensuring that there are no dark areas on both sides of the workpiece, and that the reflected light is bright and uniform, thus enhancing the illumination effect of the strobe bar.

[0039] Reference Figure 3 As shown, it can be understood that along the width direction of the outer casing 1, the height of the plurality of heat sinks 12 gradually increases from the edge of the outer casing 1 toward the first positioning platform 142. In other words, the closer the heat sink 12 is to the first positioning platform 142 in the width direction of the outer casing 1, the taller the heat sink 12 is; the closer it is to the edge of the outer casing 1, the shorter the heat sink 12 is. In this embodiment, the ends of the remaining heat sinks 12 on the same side as the tallest heat sink 12 are located on the same inclined plane. At this time, the longitudinal cross-section of all heat sinks 12 is diamond-shaped.

[0040] If the tilt angle of the outer casing 1 is adjustable, and multiple heat sinks 12 are of equal height, then when the outer casing 1 is tilted to its limit angle (e.g., 20° or 50°), the heat sink 12 near the edge of the outer casing 1 may collide and interfere with the worktable carrying the workpiece or other components inside the vision inspection system, affecting the use of the strobe light and even the accuracy of the inspection results. By setting heat sinks 12 with gradually varying heights, the heat sink 12 is the tallest at the corresponding position on the first positioning stage 142, maximizing the effective heat exchange area and ensuring the heat dissipation efficiency of the heat sink 12. At the same time, the heat sink 12 is the shortest at the edge of the outer casing 1, avoiding collision and interference between the heat sink 12 and the worktable or other components, effectively improving the structural rationality of the strobe light.

[0041] Preferably, along the thickness direction of the outer casing 1, the thickness of the outer casing 1 is less than or equal to 20 mm, and the maximum height of the heat sink 12 is less than or equal to 10 mm.

[0042] The total thickness of the outer casing 1 is limited to less than 20mm to ensure that the overall thickness of the outer casing 1 is within a controlled range, meeting the installation and use requirements of narrow spaces. The height of the heat sink 12 is limited to less than 10mm to prevent the height of the heat sink 12 from exceeding the thickness of the outer casing 1, increasing the load on the outer casing 1 and affecting the overall thickness of the outer casing 1, thus ensuring the uniformity and aesthetics of the overall structure.

[0043] Preferably, the side wall of the housing 1 is provided with a through hole, and the end of the light strip 21 is connected to a standard interface, which passes through the through hole. Specifically, the standard interface is a standard 2mm pitch pin interface at the end of the integrated light strip 21. The standard interface includes at least three pins: a power supply pin (positive and negative) and an independent strobe trigger signal pin (TRIG). It can also be expanded to 4 pins (to add a signal ground or for backup). The pin definitions are standardized to facilitate quick connection with standard DuPont wires or prefabricated wire harnesses. The interface can be a through-hole pin header or a surface-mount pad, with a foolproof notch or different pin lengths to prevent reverse insertion.

[0044] By setting up a standard interface, operators do not need to strip or solder wires when using strobe strip lighting. They only need to use standard 2mm pitch prefabricated wire harnesses (such as DuPont wires or IDC cables), insert one end into the standard interface of the strobe strip, and connect the other end to the controller or power supply to complete the electrical layout of the strobe strip. If the wiring length needs to be changed, simply replace it with a standard wire harness of the corresponding length. The whole process is convenient and quick. This significantly reduces the layout cost of strobe strip lighting and improves the ease of installation and removal.

[0045] In addition, the light strip 21 is equipped with a strobe control circuit for controlling the LED beads. The strobe control circuit is electrically connected to a standard interface and employs a high-speed MOSFET switching design with a response time in the microsecond range. Combined with a logic controller, when a signal is input, the drive current can be increased to several times (e.g., 3-5 times) of the rated value in a very short time, achieving instantaneous ultra-high brightness output. During system operation, the industrial camera controls the LED beads to turn on and off via the logic controller. When the industrial camera takes a picture, the logic controller generates a trigger signal, which is transmitted to the strobe control circuit through the trigger pin of the standardized power interface, instantly illuminating the light source module. At this time, the light source emits light with an instantaneous brightness far exceeding the rated power, working in conjunction with the camera to complete image acquisition. After exposure, the LED beads quickly return to a low-power standby state or turn off. Using strobe technology, even if the object being measured is in high-speed motion, the extremely short exposure time can effectively capture motion and obtain a clear, motion-free image.

[0046] A visual inspection system according to an embodiment of this application includes a camera and the aforementioned strobe light strip, wherein the opening of the housing 1 (i.e. the light outlet of the strobe light strip) is set to face the focal point of the camera.

[0047] Understandably, the strobe light used for internal illumination employs a secondary focusing mechanism using a focusing rod 22 and a diffuser plate 23, and features dual cooling with a heat sink 12 and a cooling channel 13. It is thin and light-emitting with uniform and bright light, making it easy to integrate the vision inspection system into a space-constrained inspection station while ensuring inspection accuracy.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
