because the industrial camera 14 is always covered by the protective cover 26 before being used, external dust or impurities can be effectively reduced from being easily adhered to the surface of the lens of the industrial camera 14, and as operators need to use the industrial camera 14 to screen workpieces, the protective cover 26 can be driven to be automatically separated and opened in opposite directions by means of downward adjustment of the action of the shooting recognition distance of the industrial camera 14;
in addition, after the operator continuously adjusts the image capturing recognition distance of the industrial camera 14 downwards, when the positions of the first magnet 29 and the second magnet 210 are on the same horizontal line, as shown in fig. 7, at this time, under the action of the repulsive force of homopolar magnetism between the first magnet 29 and the second magnet 210, the second magnet 210 drives the second magnet 28 and the second stand 211 to move to one side of the machine slide rail 12, meanwhile, the part of the second stand 211 sliding on the second stand 212 is fixedly connected with a spring, and because one end of the second stand 211 is fixedly connected with the spring on the inner wall of the second stand 212, the spring is compressed when the second stand 211 slides, and through the cooperation movement between the structures of the parts, the function of affecting the normal adjustment of the image capturing recognition distance of the industrial camera 14 can be prevented, so as to ensure the operation coordination and the order between the whole structures;
lens follow-up processing steps for timely wiping and processing impurities on the surface of the industrial camera 14:
synchronously, when two protective covers 26 move away from each other in opposite directions, one protective cover 26 fixedly connected with the central inserting shaft 31 synchronously drives the central inserting shaft 31 to move, a convex sliding block at the upper end of the central inserting shaft 31 slides along a chute track in the limiting slotted plate 35, particularly shown in fig. 10, the traction rope 36 is pulled to bear force along with the movement of the central inserting shaft 31, and the traction rope 36 winds the outer wall of the central inserting shaft 31, so when the traction rope 36 is gradually pulled to separate from the outer wall of the central inserting shaft 31, the central inserting shaft 31 which is rotationally connected with the convex sliding block rotates clockwise at the moment, the central inserting shaft 31 is meshed with the follower gear 33 through an arc-shaped rack 34 at the lower outer wall of the central inserting shaft, particularly shown in fig. 9, at the moment, one follower gear 33 meshed with the arc-shaped rack 34 rotates anticlockwise, the other follower gear 33 rotates reversely, and when the follower gear 33 rotates, the follower gear 33 drives the swing plate 32 fixedly connected with the outer wall of the central inserting shaft 31 to rotate along with the outer wall of the central inserting shaft, so that the central inserting shaft 31 rotates along with the arc-shaped rack 34, the central inserting shaft 31 rotates along with the arc-shaped rack 33, and the annular gear 33 is meshed with the follower gear 33, and the annular ring 14 is meshed with the annular ring 14, and the annular ring 14 is kept close to the annular ring 14, and the annular ring 14 is kept against the annular ring of the annular ring, and the annular ring is deformed;
because the microfiber material of the swinging plate 32 near one end of the industrial camera 14 has good wiping dust collection effect, the lens part of the industrial camera 14 can be automatically wiped by means of the rotary motion of the swinging plate 32, and an operator can automatically wipe the surface of the lens before using the industrial camera 14 each time, so that complicated steps of manual treatment are avoided, the effect of directly wiping dust collection is combined with the external protection effect of the protection cover 26, the industrial camera 14 can have better definition in the double-layer dust-blocking and dust-collecting modes, and the whole accuracy of screening workpieces by the screening equipment is facilitated;
in addition, since the lower end of the center plug shaft 31 is rotatably plugged into the bottom surface inside any one of the two protection covers 26, and the bottom surfaces inside the two protection covers 26, which are close to one side of the center plug shaft 31, are rotatably plugged with the follower gears 33, and meanwhile, the bottom covers 2601 are detachably plugged in combination with the bottoms of the two protection covers 26, when the position, which is close to one end of the industrial camera 14, of the swing plate 32 needs to be replaced or cleaned, an operator can detach the bottom cover 2601 first, and then take out the follower gears 33 together with the swing plate 32, thereby ensuring the convenience of replacement work of the internal structure of the lens follower processing mechanism in the device, and further ensuring the wiping processing effect of the swing plate 32 on the industrial camera 14.
Autonomous shade shading step for blocking external light:
in addition, as the two protection covers 26 are separated in opposite directions, if the external ambient light is too strong when the industrial camera 14 is used, or if some external light and some workpiece to be detected with smooth surface generate light reflection effect, an operator can hold the weight rod 43 and apply downward external force larger than the magnetic attraction between the magnetic rod 44 and the magnetic sheet 45 to cause the magnetic rod 44 to be separated from the magnetic sheet 45 in a sliding manner, then the weight rod 43 can be loosened, at this time, the elasticity of the light-shielding cloth 42 is smaller than the gravity of the weight rod 43, so that the light-shielding cloth 42 can be stretched downward freely under the gravity action of the weight rod 43 from the bottom of the accommodating cavity ring 41, and the stretched light-shielding cloth 42 just shields most of the space around the industrial camera 14;
at this time, the light from most of strong light in the external environment can be blocked by means of the light-shielding cloth 42 made of black nitrile rubber, meanwhile, as the bottom surface of the containing cavity ring 41 is corresponding to the light-shielding cloth 42 and is uniformly provided with the soft brushes 46 on the two sides of the position extending to the lower part of the containing cavity ring 41, when the light-shielding cloth 42 is stretched out of the inside of the containing cavity ring 41, the outer surface of the light-shielding cloth 42 can be scratched by means of the soft brushes 46, so that dust on the outer wall of the light-shielding cloth 42 is reduced, the scattering of dust on the surface of the light-shielding cloth 42 and the absorption of light are reduced, the surface of the light-shielding cloth 42 becomes uneven, so that the shading effect is reduced, compared with the prior art, the interference of the external strong light on the acquired images of the industrial camera 14 can be reduced by adopting a simple mode, meanwhile, compared with the prior art, the shading treatment step in the equipment is easier to operate by adopting a mode of simply shielding the object around a lens, and has a stable shading effect, so that the error condition of screening workpieces can be reduced due to the fact that the strong light interferes with the industrial camera 14 is identified, and the screening workpieces can be identified, and the stability of the screening can be guaranteed;
after use:
after the operator finishes screening the workpieces by using the equipment, the machine position slide rail 12 can be controlled by the controller to drive the cloud platform 13 and the industrial camera 14 to move upwards for resetting, the operator can manually move the double-rod slide block 22 upwards at the moment after the cross combined groove plate 21 is reset to an initial state, the two protection covers 26 can also be shielded on the outer wall below the industrial camera 14 again after the double-rod slide block 22 moves upwards at the moment, and meanwhile, the double-rod slide block 22 can be always positioned at the highest point of a vertical groove in the cross combined groove plate 21 under the action of elastic tension of the reset strip 25;
during the resetting of the two protection covers 26, the central shaft 31 is gradually reset, and the traction rope 36 automatically rotates and resets under the action of the rebound force of the torsion spring, so that the central shaft 31 is driven to automatically rotate and reset, and the traction rope 36 is wound back to the outer wall of the central shaft for subsequent use.
