In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] Embodiment 1

[0038] like Figure 1-16 As shown, an energy-saving light source combination device for machine vision inspection includes a light source tube frame 1, on which a plurality of light sources of different colors are installed, the light source tube frame 1 is fixed on a light source support frame 2, and a plurality of light source support frames 2 are installed on a light source disc frame 3, a light intensity sensor 4 is installed on the light source support frame 2, the light intensity sensor 4 is electrically connected to the plurality of light sources of different colors, and the light intensity sensor 4 adjusts the light intensity of the plurality of light sources of different colors according to the detected ambient light intensity;

[0039] The working principle of the above technical solution is as follows: a plurality of light sources of different colors are installed on a light source tube frame 1, wherein the different colors include white light, red light, blue light and infrared light, etc., and any color of the light source can be switched according to actual needs. The light source tube frame 1 is fixed on a light source support frame 2. By adjusting the light source support frame 2, the light source tube frame 1 can be adjusted to change the irradiation route of the light source to adapt to different shooting objects. A plurality of light source support frames 2 are installed on a light source disc frame 3, and a light source tube frame 1 is fixed on each light source support frame 2. Then, a plurality of groups of light sources will illuminate the shooting object at the center position of the light source disc frame 3, and the shooting object will be evenly illuminated without dead angles. The light intensity sensor 4 adjusts the light intensity of a plurality of light sources of different colors according to the detected ambient light intensity, which has an energy-saving effect.

[0040] It solves the problem that the light source in traditional machine vision systems cannot change its route. When using the same lighting path, the image will have shadows, highlights and other irregular brightness changes, thus affecting the accuracy of image processing and analysis.

[0041] Embodiment 2

[0042] like Figure 1-16As shown, the light source tube frame 1 includes a connecting frame 101, one end of the connecting frame 101 is fixed on the light source support frame 2, and the other end of the connecting frame 101 is fixedly connected to the fixing frame 102. The fixing frame 102 is provided with five through holes 119 for inserting the light source, and the through holes 119 near the light source support frame 2 are provided with conductive sheets 103, and the lower end of the conductive sheet 103 is connected to an elastic sheet 104;

[0043] The connecting frame 101 is fixedly connected to the motor 105, the output end of the motor 105 is connected to one end of the connecting rod 106, the other end of the connecting rod 106 is fixed to the outer cylinder fixing plate 107, five outer cylinders 108 are fixed to the outer cylinder fixing plate 107, five inner cylinders 109 are slidably connected in the five outer cylinders 108, the five inner cylinders 109 are all fixed to the inner cylinder fixing plate 110, the inner cylinder fixing plate 110 rotates in the fixing frame 102, the five inner cylinders 109 correspond to the five through holes 119 one by one, and the inner walls of the five inner cylinders 109 are provided with clamping components;

[0044] The working principle of the above technical solution is as follows: four light source bodies capable of emitting light of different colors are inserted into the combined cylinder composed of the outer cylinder 108 and the inner cylinder 109 through the four through holes 119, the front edge of the light source is against the slider 118 at the lower end of the outer cylinder 108, the motor 105 is started, the connecting rod 106 is driven to rotate 72 degrees, the outer cylinder fixing plate 107 is driven to rotate 72 degrees, the outer cylinder 108 and the inner cylinder 109 are driven to rotate 72 degrees, the combined cylinder without light source inserted is rotated out from under the elastic sheet 104, and the adjacent combined cylinder with light source inserted is rotated to under the elastic sheet 104, the rear end of the light source contacts the elastic sheet 104, and the elastic sheet 104 is squeezed and deformed, and then the light source is fixed between the slider 118 and the elastic sheet 104, and the elastic sheet 104 is electrically connected to the light source, the conductive sheet 103 is connected to the power supply through the transmission line, the elastic sheet 104 is made of conductive metal material, and the light source is powered by the elastic sheet 104, so the light source rotated to under the elastic sheet 104 can emit a light beam to illuminate the photographed object;

[0045] After the combination tube without a light source is rotated out from under the elastic sheet 104, light sources of other colors can be inserted from the corresponding through holes 119, so that there are light sources in all five combination tubes. According to actual needs, the required color light source can be rotated under the elastic sheet 104 to facilitate switching of lighting colors. At the same time, the other four light sources are easy to plug and unplug, which is convenient for replacement and maintenance.

[0046] Embodiment 3

[0047] like Figure 1-16As shown, the clamping component includes an axle wheel fixing frame 111, the axle wheel fixing frame 111 slides in the side wall of the inner cylinder 109, the axle wheel fixing frame 111 is fixedly connected to one end of a spring 112, the other end of the spring 112 is fixed to the outer wall of the inner cylinder 109, and the axle wheel 113 is rotatably connected in the axle wheel fixing frame 111, and the axle wheel 113 is rotatably connected with the sliding belt 114;

[0048] The working principle of the above technical solution is as follows: in the initial state, when the light source is not inserted into the inner cylinder 109, the volume of the sliding belt 114 in the inner cylinder 109 is smaller than the volume outside the inner cylinder 109, so as to prevent the light source from being inserted into the inner cylinder 109 and getting stuck at the upper end of the sliding belt 114. After the light source is inserted into the inner cylinder 109, the light source is preferably in contact with the upper ends of the two sliding belts 114. Due to the inclined surface of the upper end of the sliding belt 114 located in the inner cylinder 109, the light source squeezes the two sliding belts 114 to move to both sides, driving the two sets of shaft wheels 113 to move to both sides, driving the shaft wheel fixing frame 111 to move to both sides, driving the spring 112 to be stretched, and the light source continues to move downward, driving the two sliding belts 114 to rotate, driving the two sets of shaft wheels 113 to rotate, and the two sliding belts 114 rotate in contact with the outer surface of the light source, thereby clamping the light source and preventing friction with the light source, thereby causing wear on the outer surface of the light source.

[0049] The inner diameter of the inner cylinder 109 is designed to be relatively large, so that light sources of different specifications can be inserted. The two sliding belts 114 can clamp the light source to prevent it from shaking freely in the inner cylinder 109. When the light source moves downward, the outer surface of the light source will not be damaged due to friction.

[0050] Embodiment 4

[0051] like Figure 1-16 As shown, the inner cylinder fixing plate 110 is rotatably connected to the screw rod 115, and the screw rod 115 is threadedly connected to the outer cylinder fixing plate 107;

[0052] The working principle of the above technical solution is: after the light source body is inserted into the combined cylinder composed of the outer cylinder 108 and the inner cylinder 109 through the four through holes 119, the screw 115 is rotated to drive the outer cylinder 108 and the inner cylinder 109 to slide. Since the lower end of the light source is against the slider 118, the position of the upper end of the light source can be adjusted so that the upper end of the light source is located at a preset position in the inner cylinder 109 to prevent the upper end of the light source from being too high. When the fixing frame 102 and the inner cylinder fixing plate 110 rotate relative to each other, the light source is stuck in the through hole 119 to prevent the upper end of the light source from being too low. When the light source to be used is turned to the bottom of the elastic sheet 104, the elastic sheet 104 cannot be contacted, and the light source cannot be powered on to illuminate. At the same time, the screw 115 is rotated to drive the outer cylinder 108 and the inner cylinder 109 to slide, thereby changing the length of the combined cylinder to adapt to light sources of different specifications.

[0053] Embodiment 5

[0054] like Figure 1-16As shown, the outer cylinder fixing plate 107 is rotatably connected to the rotating button 116, the rotating button 116 is fixedly connected to the rotating disk 117, the rotating disk 117 is slidably connected to the five sliders 118, the five sliders 118 slide on the outer cylinder fixing plate 107, and the front ends of the five sliders 118 extend toward the center line directions of the five outer cylinders 108 respectively;

[0055] The working principle of the above technical solution is: turning the knob 116 drives the turntable 117 to rotate, driving the five sliders 118 to slide outward or retract inward, so as to cope with light sources of different specifications, so that the sliders 118 are clamped at the edge of the light source to prevent the light source from sliding out from the lower end of the inner tube fixing plate 110, and prevent the sliders 118 from extending too long to block the light source.

[0056] Embodiment 6

[0057] like Figure 1-16 As shown, the light source support frame 2 includes a rotating rod 1 201, the rotating rod 1 201 is fixedly connected to the connecting frame 101, the rotating rod 1 201 is hingedly connected to the rotating rod 2 202, the rotating rod 1 201 is hingedly connected to the rotating rod 3 203, the rotating rod 3 203 is hingedly connected to the rotating rod 4 204, the rotating rod 2 202 is rotatably connected to the rotating rod 4 204, the rotating rod 2 202 is hingedly connected to the rotating rod 5 205, the rotating rod 4 204 and the rotating rod 5 205 are all rotated in the central rod 206, the rotating rod 1 201, the rotating rod 4 204 and the rotating rod 5 205 are parallel to each other, and the central axes of the rotating rod 202, the rotating rod 3 203, the central rod 206 and the inner cylinder 109 are parallel to each other;

[0058] The central rod 206 is fixedly connected to the motor 207, the output end of the motor 207 is connected to the rotating rod 5 205, the central rod 206 is connected to the output end of the motor 3 208, the motor 3 208 is fixed on the bracket 209, and the light intensity sensor 4 is fixed on the bracket 209;

[0059] The working principle of the above technical solution is as follows: the intersection of the axial extension line of the rotating rod 1 201 and the axial extension line of the central rod 206 converges at a point, at which the photographed object can be placed, the axial extension line of the rotating rod 1 201 coincides with the central axis of the light source below the elastic sheet 104, and thus the light source below the elastic sheet 104 can directly illuminate the photographed object, start the motor 207, drive the rotating rod 5 205 to rotate, drive the rotating rod 4 204 and the rotating rod 1 201 to rotate, keep parallel to the rotating rod 5 205, drive the rotating rod 202 and the rotating rod 3 203 to rise or move downward, and drive the light source tube The frame 1 moves with the rotating rod 1 201, thereby changing the longitudinal path of the light source, but always irradiating the object to be photographed. Start the motor 3 208 to drive the center rod 206 to rotate, and drive the light source tube frame 1 to rotate through the rotating rod 1 201, the rotating rod 202, the rotating rod 3 203, the rotating rod 4 204 and the rotating rod 5 205, thereby changing the horizontal path of the light source. Since the object to be photographed is on the axial extension line of the center rod 206, the light source always irradiates the object to be photographed, and then the irradiation path can be adjusted at multiple angles in coordination with the shooting camera, and the light source always irradiates the object to be photographed.

[0060] Embodiment 7

[0061] like Figure 1-16 As shown, the bracket 209 is threadedly connected with the stud 211, a limiting disc 212 is fixed at the lower end of the stud 211, the limiting disc 212 slides in the light source disc frame 3, the bracket 209 is fixed on the light source disc frame 3, and a reinforcing rib 210 is provided at the connection between the bracket 209 and the light source disc frame 3;

[0062] The working principle of the above technical solution is: the reinforcing rib 210 can strengthen the connection between the bracket 209 and the light source disc bracket 3 to prevent bending or loosening between the two.

[0063] Embodiment 8

[0064] like Figure 1-16 As shown, the light source disc frame 3 includes a base 301, a limiting groove 302 is provided on the base 301, and the limiting disc 212 slides in the limiting groove 302. A motor 4 303 is fixed to the side of the base 301, and the output end of the motor 4 303 is connected to the gear 304. The gear 304 is engaged with the inner turntable 305 for transmission. The inner turntable 305 rotates in the base 301, and the inner turntable 305 is connected to the clamping frame 306 by clamping. The clamping frame 306 is slidably connected to the base 301. The bracket 209 is fixed on the clamping frame 306. A reinforcing rib 210 is provided at the connection between the bracket 209 and the clamping frame 306. A central storage platform 307 is provided at the center of the rotating rod 1 201, and the intersection of the axial extension line of the rotating rod 1 201 and the axial extension line of the center rod 206 is gathered on the central storage platform 307.

[0065] The working principle of the above technical solution is: the object to be photographed is placed on the central storage table 307, the light source is irradiated on the object to be photographed, the motor 4 303 is started, the gear 304 is driven to rotate, the inner turntable 305 is driven to rotate, and the multiple clamping frames 306 are driven to rotate along with the inner turntable 305, and the light source support frame 2 is driven to rotate through the bracket 209, the limiting disc 212 slides in the limiting groove 302, and the light source tube frame 1 is driven to rotate, and the multiple light sources are driven to rotate, thereby changing the illumination route;

[0066] Rotate the stud 211 to drive the limit disc 212 to rotate, drive the bracket 209 to rise a short distance, the bracket 209 pulls the clamping frame 306 to rise a short distance, drive the clamping frame 306 and the base 301 to slide, the clamping frame 306 is separated from the inner turntable 305, and start the motor 4 303 again to drive the gear 304 to rotate, drive the inner turntable 305 to rotate. Since the clamping frame 306 is separated from the inner turntable 305, the clamping frame 306 at this location will not rotate with the inner turntable 305, and the light source at this location will not rotate with it. When other light sources rotate with it, the distance between the two light sources is shortened. After the two light sources are close, a combined light source can be implemented to illuminate the photographed object, thereby adapting to different shooting scenes.
