[0029] The embodiment of the present application provides a light source device for suppressing reflection of metal cylindrical surfaces in multiple directions in machine vision, such as Figure 1 As shown, the device includes: an observation window assembly 1, which is treated by a natural color anodizing process; an end cover 2, which is fixedly assembled at both ends of the observation window assembly 1; a light board 3, which is fixedly assembled on one side of the end cover; a support plate 4, which is fixedly assembled at both ends of the end cover 2; a guide clamping mechanism 5, which is fixedly assembled on the support plate 4; and a bottom plate 6, on which the support plate 4 is fixedly assembled.

[0030] Further, such as Figure 2 As shown, the observation window assembly 1 includes: a lower observation window 12, wherein threaded holes 121 are provided at both ends of the lower observation window 12, and the lower observation window 12 is fixedly connected to the end cover 2 by screws; an upper observation window 11, wherein the upper observation window 11 is connected to the lower observation window 12 by locking screws 13; wherein the upper observation window 11 is provided with two detection holes 15 evenly arranged at 90°, and the lower observation window 12 is provided with two detection holes 15 evenly arranged at 90°.

[0031] Furthermore, the inner walls of the upper observation window 11 and the lower observation window 12 are both treated by natural color anodizing process, and the closed ends 16 of the upper observation window 11 and the lower observation window are provided with attracting magnets 14 .

[0032] Preferably, the light source device for multi-directional suppression of reflection of metal cylindrical surface in machine vision comprises an observation window assembly 1 which has been anodized in natural color, end caps 2 are fixed at both ends of the observation window assembly 1, support plates 4 are fixed at both ends of the end caps 2, a metal wire guide and clamping mechanism 5 is fixed to the support plate 4, and the support plate 4 is fixed to the bottom plate 6. Among them, the observation window assembly 1 comprises a lower observation window 12 and an upper observation window 11, threaded holes 121 are provided at both ends of the lower observation window 12, and the lower observation window 12 is fixed to the end caps 2 by screws, the upper observation window 11 is connected to the lower observation window 12 by locking screws 13, the upper observation window 11 and the lower observation window 12 are both provided with two detection holes 15, and the detection holes 15 are evenly arranged at 90 degrees, the inner walls of the upper observation window 11 and the lower observation window 12 are both treated by natural color anodizing process, and the closed end 16 of the observation window is provided with a magnet 14.

[0033] Preferably, threaded holes 121 are respectively provided at both ends of the lower observation window 12 for installing screws, and the lower observation window is firmly connected to the end cover 2 by the screws to ensure its stability inside the device; the upper observation window 11 is connected to the lower observation window 12 by locking screws 13; the upper observation window 11 and the lower observation window 12 are both provided with two detection holes, and the holes are evenly arranged at 90°, that is, the angular interval between the two detection holes is 90°, in a cross distribution or vertical cross arrangement, which is helpful to obtain detection signals or light sources from different directions, improve the comprehensiveness of detection and multi-angle observation capabilities, and is particularly suitable for imaging requirements of multi-reflective surfaces such as metal cylinders. It can enhance the multi-directional detection capability of the light source device, and achieve high stability and detachability through the combination of screws and locking screws.

[0034] Preferably, first, two pairs of attractive magnets 14 are respectively installed at the circular holes reserved at the closed ends of the lower observation window 12 and the upper observation window 11. Since this is not a force-bearing point, the two pairs of magnets can be glued here with strong glue, and the upper observation window 11 and the lower observation window 12 can be tightly fitted together by relying on the suction force of the attractive magnets 14, which is convenient for the material discharge operation; then, the lower observation window 12 and the upper observation window 11 are connected by locking screws 13 to form a magnetic flip cover structure, which abandons the operation process of guiding the threading of the one-piece observation window, saves material discharge time, and is convenient for operation; after fixing the end cover 2 to the lower observation window 12, a light source cavity can be formed. When the metal wire is to be put in, the upper observation window 11 can be gently flipped up with force. When the metal wire is to be detected, the upper observation window 11 can be closed. Four suitable industrial cameras can be set at the detection holes 15 evenly arranged at 90° intervals to simultaneously collect multi-directional images of the metal wire in the light source cavity, realizing full inspection of the cylindrical surface of the metal wire. Among them, the observation window 1 is made of ordinary aluminum alloy, and its surface treatment process is natural anodizing to ensure that the light of the lamp board 3 can be fully reflected in the light source cavity. When collecting images of the metal wire through the detection hole 15, such as Figure 3 As shown in the figure, the observation direction should maintain an 8° angle with the center line of the detection hole, which can effectively reduce the strong reflection caused by direct frontal illumination and improve the contrast and clarity of the image. It is particularly suitable for the detection of highly reflective materials (such as metal surfaces). At the same time, the plane formed by the observation direction and the center line of the detection hole should include the straight line where the metal wire is located, ensuring that the relative position between the observation light path and the metal wire is optimized, which can better capture the details of the metal wire and avoid imaging distortion or detection blind spots caused by viewing angle deviation.

[0035] Further, such as Figure 4 As shown, the end cover includes: a first end cover 21, wherein the first end cover 21 is provided with a tiny groove structure upward at the center hole, the lamp board 3 is fixed on the inner side of the first end cover 21, and a lamp board power line access groove 213 is provided; a second end cover 22, wherein the second end cover 22 is provided with a tiny groove structure upward at the center hole; wherein the first end cover 21 and the lamp board 3 are fixed by heat-resistant adhesive.

[0036] Preferably, the end cover 2 includes a first end cover 21 and a second end cover 22, and the first end cover 21 and the second end cover 22 are both provided with a tiny groove structure (i.e., the end cover groove 211) upward from the center hole 212, and a lamp board 3 is fixed on the inner side of the first end cover 21, and the first end cover 21 and the lamp board 3 are fixed by heat-resistant adhesive, and a lamp board power cord access groove 213 is provided on the inner side of the first end cover.

[0037] Preferably, the tiny slotted structure of the end cover 2 can facilitate the operation of placing the metal wire into the light source cavity. The light board 3 can be installed on the first end cover 21 through the heat-resistant adhesive to ensure that the light source can evenly illuminate the detected object. The first end cover 21 can also be used as a passive heat dissipation device for the light board 3, which can extend the service life of the light board 3 to a certain extent, including extending the service life of the LED lamp beads. The single-sided same-direction stroboscopic lighting method can be used for fast, short, high-intensity flashes. Compared with traditional continuous lighting, the stroboscopic lighting method only releases light energy in a short time and will not increase the heat load on the surface of the object for a long time. The power supply line 215 of the light board is connected to the contact on the back of the light board 3 through the power access slot 213 of the first end cover 21. The wiring structure is compact and provides a more uniform stress distribution. In addition, a compression rubber ring 214 is provided at the power access slot 213 to prevent loosening, shock resistance and firm fixation. It is suitable for the long-term stable operation of electronic components such as LED light boards, and extends the service life of the light board 3.

[0038] Further, such as Figure 5 As shown, the lamp board 3 adopts a slotted structure, the lamp board 3 adopts high-efficiency cold white LED lamp beads, and the lamp board lamp beads 32 adopt a 7-series and 3-parallel connection structure.

[0039] Preferably, the lamp board 3 adopts a slotted structure design (i.e., the lamp board slot 31), which can facilitate the insertion of metal wire into the light source cavity. This design not only improves the assembly efficiency, but also facilitates later maintenance; the lamp board adopts cold white LED lamp beads (i.e., lamp beads 32) as light-emitting units, which have high light intensity and can provide a clear and bright light source to meet the high requirements for lighting intensity and stability in industrial environments. In addition, the lamp board is equipped with a 24V power supply to ensure the stable operation of the equipment in an industrial environment, while also meeting the standard requirements for power supply voltage for conventional industrial equipment.

[0040] Further, such as Figure 6 As shown, the support plate 4 is a mirror image part, including a first support plate 41 and a second support plate 42 , and both the first support plate 41 and the second support plate 42 are provided with an upwardly grooved structure.

[0041] Furthermore, a strip groove is provided at the connection between the support plate 4 and the guide and clamping mechanism 5, and the guide and clamping mechanism 5 can be slightly adjusted in the horizontal direction.

[0042] Preferably, a strip groove is provided at the connection between the support plate 4 and the guide and clamping mechanism 5, and the support plate 4 is provided with an upwardly slotted structure (i.e., the support plate slot 411). The support plate 4 is a mirrored part, namely the first support plate 41 and the second support plate 42. The guide and clamping mechanism 5 can be slightly adjusted in the horizontal direction, wherein the metal wire to be detected needs to pass through the center holes of the first end cover 21 and the second end cover 22. Through the support plate strip groove 412, the assembler can easily adjust the position of the parts, thereby ensuring the accuracy and stability of the overall structure, thereby effectively improving the assembly efficiency and reducing the rework or adjustment time caused by errors.

[0043] Further, such as Figure 7 , Figure 8 As shown, the guide and clamping mechanism 5 is a mirror image part, including a first guide and clamping mechanism 51 and a second guide and clamping mechanism 52 . Among them, the first guiding and clamping mechanism 51 or the second guiding and clamping mechanism 52 includes: a guide wheel strip groove 513, the guide wheel strip groove 513 is a V-groove structure; a clamping wheel sliding groove 514, the clamping wheel sliding groove 514 is a V-groove structure; an adjusting screw 516; a slider 515, the slider 515 is connected to the adjusting screw 516; a guide wheel 512, the guide wheel 512 is used to guide the metal wire, and the guide wheel 512 is slightly adjusted in the vertical direction in the guide wheel strip groove 513; a clamping wheel 511, the clamping wheel 511 is fixedly connected to the slider 515, the clamping wheel 511 is used to firmly clamp the two ends of the metal wire, and the clamping wheel 511 is greatly adjusted in the vertical direction in the clamping wheel sliding groove 514; wherein the horizontal tangent of the top of the guide wheel strip groove 513 and the bottom of the clamping wheel sliding groove 514 are coplanar with the center line of the end cover 2 in the vertical direction.

[0044] Preferably, the guide and clamping mechanism 5 is a mirrored part, namely a first guide and clamping mechanism 51 and a second guide and clamping mechanism 52, wherein the guide and clamping mechanism 5 includes a guide wheel 512, a clamping wheel 511, a guide wheel strip groove 513, a clamping wheel sliding groove 514, a slider 515 and an adjusting screw 516. The guide wheel 512 can be slightly adjusted in the vertical direction in the guide wheel strip groove 513, and the clamping wheel 511 can be greatly adjusted in the vertical direction in the clamping wheel sliding groove 514. The clamping wheel 511 is fixed on the slider 515, and the slider 515 is connected to the adjusting screw 516. The horizontal tangents of the top of the V-groove of the guide wheel 512 and the bottom of the V-groove of the clamping wheel 511 are coplanar with the center line of the end cover in the vertical direction.

[0045] Preferably, the guide wheel 512 in the two guiding and clamping mechanisms (the first guiding and clamping mechanism 51 and the second guiding and clamping mechanism 52) is responsible for guiding the metal wire to ensure that it is stably located in the V-groove of the guide wheel 512, thereby effectively limiting the violent movement of the wire in the front and rear directions; and the clamping wheel 511 is responsible for firmly clamping the two ends of the metal wire. When the wire continuously passes through the light source cavity under a certain tension, if the metal wire located on the outside of the clamping wheel 511 shakes significantly, its effect on the metal wire in the light source cavity is minimal, that is, after the metal wire passes through the first guiding and clamping mechanism 51 and the second guiding and clamping mechanism 52 in turn, the shaking amount of the metal wire in the high-brightness light source cavity will be kept within a very small range, which is convenient for the high-magnification telecentric lens to perform accurate image acquisition, thereby ensuring the stability of the metal wire in the light source cavity.

[0046] The above specific implementation manner does not constitute a limitation to the protection scope of the present application. It should be understood by those skilled in the art that various modifications, combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application. In some cases, the actions or steps recorded in the present application can be performed in an order different from that in the embodiment and can still achieve the desired results. In addition, the process depicted in the accompanying drawings does not necessarily require the specific order or continuous order shown to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
