Description

Technical Field

[0001] This invention relates to the field of machine vision technology, and in particular to a strip light source for an industrial camera that is adjustable at multiple angles. Background Technology

[0002] Adjustable angle strip light source is an industrial vision lighting component with integrated active cooling system. Its core structure consists of a high-density LED module, a heat dissipation housing that combines heat dissipation fins and a fan. This design ensures thermal stability under high power through efficient heat dissipation, while its mechanical joints allow the light source to be flexibly adjusted around the axis to meet the diverse lighting needs of complex surface inspection.

[0003] While the multi-angle adjustable bracket changes the orientation of the light source, it also causes the heat sink housing, which integrates the fan and directional airflow, to deviate from the preset working angle. This interferes with the internal forced convection airflow organization and the heat conduction direction of the heat sink fins, ultimately leading to a decrease in the performance of the preset high-efficiency active cooling system. Summary of the Invention

[0004] Therefore, it is necessary to address the problem that current adjustable angle bar light sources suffer from heat dissipation interference due to angle changes, leading to unstable operation of the bar light source, and to provide a multi-angle adjustable bar light source for industrial cameras.

[0005] A multi-angle adjustable strip light source for industrial cameras, comprising:

[0006] Universal bracket;

[0007] A light source module is located at the adjustment part of the universal bracket;

[0008] A heat-conducting outer frame is provided at the adjustment part of the universal bracket. The light source module is fixedly connected to the inside of the heat-conducting outer frame by bolts. The wiring terminal of the light source module extends to the outside of the heat-conducting outer frame. An air inlet is provided at the top of the heat-conducting outer frame, and air guide grooves are provided at both sides of the heat-conducting outer frame.

[0009] A composite optical component, wherein the composite optical component is fixedly connected to the bottom opening of the heat-conducting outer frame;

[0010] Two forced heat dissipation mechanisms are provided. Each forced heat dissipation mechanism includes a mounting frame fixedly connected between the side end of the heat-conducting outer frame and the universal bracket drive part. The end of the mounting frame facing the light source module has a mounting cavity communicating with the side opening of the heat-conducting outer frame. Both sides of the mounting frame have a first air guide channel communicating with the mounting cavity and the adjacent air guide groove. The bottom of the mounting frame has a second air guide channel communicating with the mounting cavity. The exhaust opening of the second air guide channel faces the composite optical component. A miniature fan is fixedly connected inside the mounting cavity. The air blowing direction of the miniature fan is from the air inlet to the mounting cavity.

[0011] In one embodiment, the vertical cross-sectional shape of the air guide groove is an inclined grid, and the intersection of the heat-conducting outer frame and the air guide groove forms a heat-conducting column with a vertical cross-sectional shape of rhombus.

[0012] In one embodiment, the number of first air channels disposed on the same side of the mounting frame is not less than three, and the first air channels disposed on the same side of the mounting frame are respectively connected to the adjacent openings of the air channel.

[0013] In one embodiment, the corners of the junction of two adjacent first air channels are beveled, and the local vertical cross-sectional shape of the mounting frame at the junction of two adjacent first air channels is an isosceles triangle.

[0014] In one embodiment, the bottom of the mounting frame is fixedly connected to an air guide shroud with an exhaust opening facing the bottom surface of the composite optical component, and the air inlet of the air guide shroud is connected to the exhaust opening of the second air guide channel.

[0015] In one embodiment, a dustproof mesh is embedded inside the air inlet, and the top surface of the dustproof mesh is flush with the upper opening of the air inlet.

[0016] In one embodiment, the top of the heat-conducting outer frame is provided with a mounting groove communicating with the air inlet, and a magnetic frame is embedded in the mounting groove, with the dustproof net fixedly connected to the inner side of the magnetic frame.

[0017] In one embodiment, a permanent magnet is embedded in the inner bottom wall of the mounting groove, and the permanent magnet is attracted to the magnetic frame.

[0018] In one embodiment, a handle is fixedly connected to the top of the magnetic frame, and the handle is n-shaped.

[0019] In one embodiment, two arc-shaped baffles are fixedly connected to both sides of the heat-conducting outer frame, and the upper opening of the air guide groove is located below the adjacent arc-shaped baffle.

[0020] 1. The above-mentioned multi-angle adjustable strip light source for industrial cameras has a heat conduction path and heat dissipation surface that are independent of the installation angle through its air guide groove and diamond heat conduction column. This solves the problem of heat dissipation performance degradation when the light source is adjusted at multiple angles. In addition, the diamond heat conduction column optimizes airflow organization, reduces flow resistance, and improves overall thermal stability while increasing the heat dissipation area.

[0021] 2. The forced heat dissipation mechanism forms a closed forced convection circulation air duct through a micro fan and the first air guide channel, ensuring that the airflow always evenly covers the heat dissipation area of ​​the heat-conducting outer frame, solving the problem of airflow organization disorder caused by angle changes. In addition, the second air guide channel directs the split airflow to the composite optical component, realizing the dual functions of heat dissipation and optical component cooling and dust prevention.

[0022] 3. The coordinated design of the arc-shaped baffle plate of the heat-conducting outer frame and the forced heat dissipation mechanism effectively prevents hot airflow from flowing back to the air inlet, avoids thermal short circuit, and solves the problem of efficiency degradation of the heat dissipation system. Furthermore, this design can automatically maintain efficient heat dissipation when the light source is adjusted at any angle, and the structure is simple and reliable, requiring no additional adjustments.

[0038] The following is combined Figure 1 - Figure 7 This invention describes a multi-angle adjustable strip light source for industrial cameras.

[0039] In one embodiment, a multi-angle adjustable strip light source for an industrial camera includes: a universal bracket 100, a light source module 200, a heat-conducting outer frame 300, a composite optical component 400, and two forced heat dissipation mechanisms 500.

[0040] like Figure 1 and Figure 2 As shown, the universal bracket 100 includes a mounting base. A Y-axis adjustment assembly is fixedly connected to the bottom of the mounting base. An X-axis adjustment assembly is fixedly connected to the drive portion of the Y-axis adjustment assembly. A U-shaped frame is fixedly connected to the drive portion of the X-axis adjustment assembly. Both sides of the U-shaped frame are rotatably connected to a rotating shaft fixedly connected to an adjacent forced cooling mechanism 500. A Z-axis adjustment assembly is fixedly connected to one side of the U-shaped frame and fixedly connected to an adjacent rotating shaft. The X-axis and Z-axis adjustment assemblies have identical structures. Figure 7 As shown, the X-axis adjustment assembly includes a mounting box fixedly connected to the drive unit of the Y-axis adjustment assembly. A rotating shaft is rotatably connected inside the mounting box. The bottom of the rotating shaft extends through the mounting box and is fixedly connected to a U-shaped frame. A worm gear, located inside the mounting box, is fixedly connected to the arc surface of the rotating shaft. The teeth of the worm gear mesh with a worm that is rotatably connected to the mounting box. One end of the worm is fixedly connected to a hexagonal adjustment seat. The adjustment part of the hexagonal adjustment seat extends through the mounting box. Figure 1 As shown, the Y-axis adjustment assembly, like the X-axis adjustment assembly, has a mounting box, a rotating shaft, a worm gear, a worm, and a hexagonal adjustment seat. However, unlike the X-axis adjustment assembly, the Y-axis adjustment assembly has both ends of the rotating shaft extending through the mounting box, and both ends of the rotating shaft are fixedly connected to a connecting plate that is fixedly connected to the mounting box in the X-axis adjustment assembly.

[0041] The multi-angle adjustment process of this strip light source via the universal bracket 100 is as follows:

[0042] When adjusting the pitch angle of the universal bracket 100, a hex wrench needs to be inserted into the hexagonal adjustment seat of the Y-axis adjustment assembly at the bottom of the mounting base and rotated. This operation drives the worm gear inside the mounting box to rotate. The worm gear meshes with and drives the worm wheel to rotate. The worm wheel is fixedly connected to the rotating shaft. The two ends of the rotating shaft pass through the mounting box and drive the connecting plate, thereby driving the entire X-axis adjustment assembly, U-shaped bracket and light source assembly above to adjust the pitch angle around the Y-axis. After the adjustment is completed, the worm gear mechanism automatically locks in position.

[0043] When adjusting the horizontal swing angle, a hex wrench needs to be inserted into the hexagonal adjustment seat of the X-axis adjustment component located on the drive part of the Y-axis adjustment component and rotated. This operation drives the worm gear inside the mounting box to rotate, and the worm gear meshes with and drives the worm wheel to rotate. The worm wheel is fixedly connected to the rotating shaft, and the bottom of the rotating shaft passes through the mounting box and is fixedly connected to the U-shaped frame. This drives the U-shaped frame and the Z-axis adjustment component and the light source assembly mounted on it to swing horizontally around the vertical X-axis axis. After the adjustment is completed, the worm gear mechanism automatically locks in position.

[0044] When adjusting the rotation angle of the light source itself, a hex wrench needs to be inserted into the hexagonal adjustment seat of the Z-axis adjustment component located on the side of the U-shaped frame and rotated. This operation drives the worm gear inside the mounting box to rotate. The worm gear meshes and drives the worm wheel to rotate. The worm wheel is fixedly connected to the rotating shaft, and the rotating shaft is fixedly connected to the forced heat dissipation mechanism 500 on both sides. The forced heat dissipation mechanism 500 is fixed to the heat-conducting outer frame 300, thereby driving the entire light source body, including the heat-conducting outer frame 300, the light source module 200, and the composite optical component 400, to rotate and adjust around the optical axis, i.e., the Z-axis. After the adjustment is completed, the worm gear mechanism automatically locks its position.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, the light source module 200 is located at the adjustment part of the universal bracket 100. The core of the light source module 200 is a high-density LED array composed of LED beads using high-brightness surface mount technology. The array is precisely arranged in multiple rows and soldered onto a metal-based printed circuit board that serves as the carrier. A mounting strip coated with high-performance thermal grease is fixedly connected to the back of the circuit board and is fixedly connected to the thermally conductive outer frame 300 by welding to form a heat conduction path. The electrical part includes a constant current drive circuit board that provides a stable current to the LED array, as well as multi-core waterproof connector terminals. The connecting cable contains a power line, a pulse width modulation brightness adjustment signal line, and an intelligent control line. The entire light-emitting unit is encapsulated in a thin-walled metal shell, and the end of the connecting cable extends through the thermally conductive outer frame 300.

[0046] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the heat-conducting outer frame 300 is located at the adjustment position of the universal bracket 100, serving as the core structural carrier and heat dissipation foundation of the entire light source body. The light source module 200 is fixedly connected to the inside of the heat-conducting outer frame 300 by bolts to establish a stable mechanical connection and a direct heat conduction path. The wiring terminals of the light source module 200 extend to the outside of the heat-conducting outer frame 300, realizing the external lead-out of the electrical connection and maintaining the airtightness of the shell. An air inlet 310 is provided at the top of the heat-conducting outer frame 300, serving as the inlet for cooling airflow and connecting with the strong... The heat dissipation mechanism 500, in conjunction with the heat dissipation system, forms a clearly defined forced convection heat dissipation airflow channel. Air guide grooves 320 are provided on both sides of the heat-conducting outer frame 300 to construct lateral airflow channels and connect with the first air guide channel 512 of the mounting frame 510 to form a heat dissipation airflow circulation path. A dustproof mesh 340 is embedded inside the air inlet 310, effectively filtering the intake air and preventing dust from entering the light source and contaminating the optical components and light source module 200. The top surface of the dustproof mesh 340 is flush with the upper opening of the air inlet 310 to maintain a flat appearance and avoid... Interference; The top of the heat-conducting outer frame 300 is provided with a mounting groove 350 communicating with the air inlet 310, providing installation space for the magnetic fixing assembly. A magnetic frame 360 ​​is embedded in the mounting groove 350, serving as a support frame for the dustproof net 340 and achieving magnetic adsorption fixation. The dustproof net 340 is fixedly connected to the inner side of the magnetic frame 360. A permanent magnet 370 is embedded in the inner bottom wall of the mounting groove 350, providing a stable magnetic adsorption force. The permanent magnet 370 is attracted to the magnetic frame 360, realizing the assembly of the dustproof net 340. The quick tool-free disassembly and assembly of the components greatly facilitates daily cleaning and maintenance; the top of the magnetic frame 360 ​​is fixedly connected to a handle 380, providing a convenient force point for disassembly operations, and the handle 380 is n-shaped; both sides of the heat-conducting outer frame 300 are fixedly connected to arc-shaped baffles 390, which can physically prevent the hot airflow rising from the air guide groove 320 from being re-drawn into the top air inlet 310, thereby effectively preventing thermal short circuits and maintaining heat dissipation efficiency; the upper opening of the air guide groove 320 is located below the adjacent arc-shaped baffles 390.

[0047] like Figure 2 As shown, the composite optical component 400 is fixedly connected to the bottom opening of the heat-conducting outer frame 300. The composite optical component 400 includes, along the optical path direction, a microstructure diffuser plate mounted close to the light-emitting surface of the light source module 200; a first layer is a light-diffusing layer made of optical-grade polymethyl methacrylate or polycarbonate; a second layer is a linear polarizer mounted at the bottom of the light-diffusing layer; and a third layer is a sealed protective panel made of high-transmittance flat glass, which is fixed and sealed to the heat-conducting outer frame 300 by an external pressure frame and a silicone sealing ring.

[0048] The process of this bar-shaped light source assisting the industrial camera is as follows: External power and control signals are connected to the light source module 200 via a multi-core waterproof connector. The constant current drive circuit board receives pulse width modulation brightness adjustment signals and enable control signals, driving the high-density LED array to emit light. The light is first initially scattered by a microstructure diffuser, then uniformly distributed by a light-diffusing layer, then surface reflections are eliminated by a linear polarizer, and finally it is emitted through the high-transmittance flat glass of the sealed protective panel, providing uniform, polarized bar illumination for the industrial camera. The entire optical path is sealed by an external pressure frame and a silicone sealing ring.

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the forced heat dissipation mechanism 500 includes a mounting frame 510 fixedly connected between the side end of the heat-conducting outer frame 300 and the driving part of the universal bracket 100. This frame serves as the main structural element of the heat dissipation mechanism and integrates with the light source and bracket. One end of the mounting frame 510 facing the light source module 200 has a mounting cavity 511 communicating with the side opening of the heat-conducting outer frame 300, forming an airflow gathering and conversion chamber and providing mounting space for the micro fan 520. Both sides of the mounting frame 510 have first air-guiding channels 512 communicating with the mounting cavity 511 and the adjacent air-guiding grooves 320, used to guide the heated airflow flowing through the light source module 200 back to the heat-conducting outer frame 300. In the air guide groove 320 of the 00, the rhomboid heat-conducting column 330 is enhanced by blowing to form a highly efficient heat dissipation airflow circuit. The bottom of the mounting frame 510 is provided with a second air guide channel 513 communicating with the mounting cavity 511, providing an outlet path for another diverted airflow. The exhaust opening of the second air guide channel 513 faces the composite optical component 400, guiding the airflow to blow onto the surface of the optical component to achieve the dual purpose of cooling and cleaning. A micro fan 520 is fixedly connected inside the mounting cavity 511, serving as the core power source for active heat dissipation to drive the forced circulation of airflow in the entire system. The blowing direction of the micro fan 520 is from the air inlet 310 to the mounting cavity 511. Direction; the vertical cross-sectional shape of the air guide groove 320 is an inclined grid, and the intersection of the heat-conducting outer frame 300 and the air guide groove 320 forms a heat-conducting column 330 with a vertical cross-sectional shape of rhombus. This specific shape greatly increases the heat dissipation surface area, optimizes heat conduction efficiency, and maintains structural strength; the number of first air guide channels 512 located on the same side of the mounting frame 510 is not less than three, ensuring that the return airflow can evenly cover the heat dissipation area on the side of the heat-conducting outer frame 300 to avoid local overheating. The first air guide channels 512 located on the same side of the mounting frame 510 are respectively connected to the adjacent openings of the air guide groove 320; two adjacent first air guide channels 51 The corners at the junction of the two first air guide channels 512 are beveled to optimize airflow direction and reduce flow resistance and turbulence. The local vertical cross-sectional shape of the mounting frame 510 at the junction of the two adjacent first air guide channels 512 is an isosceles triangle, which further conforms to the aerodynamic principle to reduce wind noise and improve fan efficiency. The bottom of the mounting frame 510 is fixedly connected to an air guide cover 530 with the exhaust opening facing the bottom surface of the composite optical component 400. This air guide cover 530 rectifies the airflow from the second air guide channel 513, making it form a concentrated airflow parallel to the surface of the optical component to enhance cooling and dust prevention. The air inlet of the air guide cover 530 is connected to the exhaust outlet of the second air guide channel 513.

[0050] Working principle: When the micro fan 520 is started, the external airflow is drawn into the heat-conducting outer frame 300 through the dustproof net 340 and the air inlet 310. It flows through the light source module 200 and carries away the heat. At the same time, the diamond-shaped heat-conducting columns 330 of the heat-conducting outer frame 300 conduct the heat out and the airflow accelerates the heat dissipation. After the heated airflow enters the mounting cavity 511, part of it flows back to the air guide groove 320 through the first air guide channel 512 to enhance the heat dissipation of the heat-conducting columns 330. The arc-shaped baffle plate 390 prevents the hot airflow from flowing back to the air inlet 310. The other part flows through the second air guide channel 513 and passes through the air guide cover 530 to blow parallel to the bottom panel of the composite optical component 400, reducing its temperature and preventing dust from adhering.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
