Description

Technical Field

[0002] The hot filament is an important part of the hot cathode structure. The hot filament is heated by passing an electric current to provide a stable high-temperature environment required for the hot cathode, enabling the cathode material to release electrons. The quality of the hot filament directly affects the emission efficiency, lifespan, and working stability of the cathode. Currently, during the production process of the hot filament, it is necessary to detect whether there are defects at the unprocessed raw material of the hot filament. The unprocessed raw material is usually a roll of continuously wound metal wire. By means of manual sampling inspection and using a microscope to observe the surface of the metal wire, when there are defects, the defective wire is marked. However, the reflection of the cylindrical surface of the metal wire seriously affects the identification of its surface defects, and using a microscope to observe the metal wire can only observe the surface of the metal wire facing the microscope lens, and its back cannot be effectively observed. Although the metal wire can be rotated manually for detection, there are problems such as repeated focusing, complex operation, and low efficiency.

[0029] The embodiment of this application provides a light source device for multi-directionally suppressing the reflection of a metal cylindrical surface in machine vision, as Figure 1 shown. The device includes: an observation window assembly 1, and the observation window assembly 1 is processed by a natural color anodizing process; an end cover 2, and the end cover 2 is fixedly assembled at both ends of the observation window assembly 1; a lamp board 3, and the lamp board 3 is fixedly assembled on one side end cover; a support plate 4, and the support plate 4 is fixedly assembled at both ends of the end cover 2; a guiding and pressing mechanism 5, and the guiding and pressing mechanism 5 is fixedly assembled on the support plate 4; a bottom plate 6, and the support plate 4 is fixedly assembled on the bottom plate 6.

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

[0031] Furthermore, the inner walls of the upper observation window 11 and the lower observation window 12 are both treated with the natural color anodizing process, and the closing 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 the reflection of the metal cylindrical surface in machine vision includes an observation window assembly 1 treated with natural color anodizing. 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 guiding and pressing mechanism 5 is fixed on the support plates 4, and the support plates 4 are fixed on a bottom plate 6. Among them, the observation window assembly 1 includes 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 are 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. Two detection holes 15 are provided on both the upper observation window 11 and the lower observation window 12. The detection holes 15 are evenly arranged at 90°. The inner walls of the upper observation window 11 and the lower observation window 12 are both treated with the natural color anodizing process, and attracting magnets 14 are provided at the closing ends 16 of the observation windows.

[0033] Preferably, threaded holes 121 are provided at both ends of the lower observation window 12 for installing screws, and the lower observation window is firmly connected to the end cap 2 by 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; two detection holes are provided on both the upper observation window 11 and the lower observation window 12, and the holes are evenly arranged at 90°, that is, the angular interval between the two detection holes is 90°, showing a cross distribution or a perpendicular cross arrangement, which helps to obtain detection signals or light sources from different directions, improves the comprehensiveness of detection and the multi-angle observation ability, is especially suitable for the imaging requirements of a metal cylindrical surface with multiple reflection surfaces, can enhance the multi-directional detection ability of the light source device, and realizes high stability and detachable property through the combination of screws and locking screws.

[0034] Preferably, first, the two pairs of attracting 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 stress point, strong glue can be used to paste the two pairs of magnets here. Relying on the suction force of the attracting magnets 14, the upper observation window 11 and the lower observation window 12 can be closely fitted, facilitating the feeding operation. Then, the lower observation window 12 and the upper observation window 11 are connected by the locking screws 13 to form a magnetic flip structure, eliminating the operation process of guiding wire threading required for the integral observation window, saving the feeding time and being convenient to operate. After the end cap 2 is fixed to the lower observation window 12, a light source cavity can be formed. When putting in the metal wire, the upper observation window 11 can be gently flipped up. When detecting the metal wire, the upper observation window 11 can be closed. At the detection holes 15 evenly arranged at intervals of 90°, four suitable industrial cameras can be respectively set to simultaneously collect multi-directional images of the metal wire in the light source cavity, realizing the full inspection of the circumference of the metal wire cylinder surface. Among them, the observation window 1 is made of ordinary aluminum alloy, and its surface treatment process is natural anodization to ensure that the light of the lamp board 3 can be fully reflected in the light source cavity. When collecting the image of the metal wire through the detection hole 15, as Figure 3 shown, the observation direction should maintain an 8° angle with the center line direction of the detection hole, which can effectively reduce the strong reflection caused by direct front illumination, improve the contrast and clarity of the image, and is especially suitable for the detection of highly reflective materials (such as the metal surface). At the same time, the plane formed by the observation direction and the center line of the detection hole should contain the straight line where the metal wire is located, ensuring the optimization of the relative position between the observation optical path and the metal wire, being able to better capture the details of the metal wire, and avoiding imaging distortion or detection blind spots caused by viewing angle deviation.

[0035] Furthermore, as Figure 4 shown, the end cap includes: a first end cap 21, the first end cap 21 is provided with a micro-grooving structure upward at the central hole, the lamp board 3 is fixed inside the first end cap 21, and a lamp board power supply wire access slot 213 is provided; a second end cap 22, the second end cap 22 is provided with a micro-grooving structure upward at the central hole; wherein, the first end cap 21 and the lamp board 3 are fixed by heat-resistant back glue.

[0036] Preferably, the end cap 2 includes a first end cap 21 and a second end cap 22. The first end cap 21 and the second end cap 22 are both provided with a micro-grooving structure (i.e., the end cap groove 211) upward at the central hole 212. The lamp board 3 is fixed inside the first end cap 21. The first end cap 21 and the lamp board 3 are fixed by heat-resistant back glue, and a lamp board power supply wire access slot 213 is provided inside the first end cap.

[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-shaped groove is provided at the connection between the support plate 4 and the guiding and pressing mechanism 5. The support plate 4 is provided with a structure with an upwardly opened groove (i.e., the support plate groove 411). The support plate 4 is a mirror part, which are respectively the first support plate 41 and the second support plate 42. The guiding and pressing mechanism 5 can be slightly adjusted in the horizontal direction. Among them, the metal wire to be detected needs to pass exactly through the central holes of the first end cover 21 and the second end cover 22. Through the strip-shaped groove 412 of the support plate, the assembler can easily adjust the position of the parts, thereby ensuring the accuracy and stability of the overall structure, effectively improving the assembly efficiency, and reducing the rework or adjustment time caused by errors.

[0043] Furthermore, as Figure 7 , Figure 8 shown, the guiding and pressing mechanism 5 is a mirror part, including a first guiding and pressing mechanism 51 and a second guiding and pressing mechanism 52. Among them, the first guiding and pressing mechanism 51 or the second guiding and pressing mechanism 52 includes: a guide wheel strip-shaped groove 513, the guide wheel strip-shaped groove 513 is a V-groove structure; a pressing wheel sliding groove 514, the pressing 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-shaped groove 513; a pressing wheel 511, the pressing wheel 511 is fixedly connected to the slider 515, the pressing wheel 511 is used to firmly press both ends of the metal wire, and the pressing wheel 511 is greatly adjusted in the vertical direction in the pressing wheel sliding groove 514; among them, the horizontal tangent line at the top of the guide wheel strip-shaped groove 513 and the bottom of the pressing wheel sliding groove 514 are coplanar with the center line of the end cover 2 in the vertical direction.

[0044] Preferably, the guiding and pressing mechanism 5 is a mirror part, which are respectively the first guiding and pressing mechanism 51 and the second guiding and pressing mechanism 52. Among them, the guiding and pressing mechanism 5 includes a guide wheel 512, a pressing wheel 511, a guide wheel strip-shaped groove 513, a pressing 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-shaped groove 513, the pressing wheel 511 can be greatly adjusted in the vertical direction in the pressing wheel sliding groove 514, the pressing wheel 511 is fixed on the slider 515, the slider 515 is connected to the adjusting screw 516, and the horizontal tangent line at the top of the V-groove of the guide wheel 512 and the bottom of the V-groove of the pressing wheel 511 are coplanar with the center line of the end cover in the vertical direction.

[0045] Preferably, the guide wheels 512 in the two guiding and pressing mechanisms (the first guiding and pressing mechanism 51 and the second guiding and pressing mechanism 52) are responsible for guiding the metal wire, ensuring that it is stably located in the V-shaped groove of the guide wheel 512, thereby effectively restricting the drastic movement of the wire in the front and back directions; while the pressing wheel 511 is responsible for firmly pressing both ends of the metal wire. When the wire continuously passes through the light source cavity under a certain tension, if the metal wire outside the pressing wheel 511 undergoes large fluctuations, the impact on the metal wire in the light source cavity is minimal. That is, when the metal wire passes through the first guiding and pressing mechanism 51 and the second guiding and pressing mechanism 52 in sequence, the fluctuation amount of the metal wire at the high-brightness light source cavity will be maintained within a very small range, facilitating accurate image acquisition by the high-magnification telecentric lens, thus ensuring the stability of the metal wire in the light source cavity.

Additionally, the processes depicted in the drawings do not necessarily require the specific order or continuous order shown to achieve the desired results. In certain embodiments, multitasking and parallel processing are also possible or may be advantageous.
