When the workpiece passes through the conveyor line, the light is irradiated on the workpiece to form a light spot. The light spot produces diffuse reflection so that the light source module 3 captures the light signal generated by the diffuse reflection and transmits the light signal to the photoelectric module 2. A No. 1 frame 6 and two No. 2 frames 7 are installed inside the shell 1. The No. 1 frame 6 is located between the two No. 2 frames 7. A ball ring 47 is rotatably installed on the No. 1 frame 6. The outer wall of the outer cylinder 42 is provided with a threaded groove. The ball ring 47 is sleeved on the outer cylinder 42. The inner wall of the ball ring 47 is provided with a ball that is slidably connected to the threaded groove of the outer cylinder 42. When the ball ring 47 rotates, the ball inside it moves along the outer cylinder 4 2 slides, so that the ball applies a horizontal thrust to the thread groove, and the ball ring 47 can drive the outer cylinder 42 to move when it rotates. The outer wall of the ball ring 47 is connected to a gear ring 48. Slide rods 49 are slidably installed on the two No. 2 frames 7.

The end of the rotating rod 412 away from the sliding rod 49 is installed with a buffer plate 413 through a spring. When the workpiece moves from back to front, the workpiece contacts the buffer plate 413 during movement. The buffer plate 413 can provide a certain buffer to the workpiece to avoid damage to the workpiece. When the workpiece continues to move forward, the rotating rod 412 is pushed through the buffer plate 413 to make the rotating rod 412 rotate around the mounting shaft 411. The rotating rod 412 uses the lever principle to push the sliding rod 49 backward for a distance through the cooperation of the bearing and the slide groove.The slide bar 49 can move a corresponding distance according to the width of different workpieces. When the width of the workpiece is large, the slide bar 49 moves a long distance, so that the ball ring 47 drives the outer cylinder 42 to move to the right more by rotation. At this time, the light spot is reduced. Since the width of the workpiece is large, the distance between the workpiece and the spotlight 9 is short. By reducing the light spot, the light spot can be adjusted to a more suitable size, which is convenient for the light source module 3 to collect diffuse reflection light signals. On the contrary, when the workpiece is small, the ball ring 47 drives the outer cylinder 42 to move to the right by rotation. The reduction amplitude of the light spot is small. At this time, the light spot is large. Since the distance between the small workpiece and the spotlight 9 is far, the larger light spot is also convenient for the light source module 3 to collect diffuse reflection light signals. From the perspective of the light source module 3, The observed sizes of the smaller light spot of the near light source module 3 and the larger light spot far away from the light source module 3 are similar, so that the light spots presented by the light on workpieces of different sizes are suitable for the light source module 3 to collect light signals, achieving the effect of adaptively adjusting the light spot size according to the size of the workpiece; an installation groove is provided on the light source module 3, and an adjusting screw rod 415 is rotatably installed in the installation groove of the light source module 3, the adjusting screw rod 415 passes through the light source module 3, one section of the adjusting screw rod 415 is located inside the inner cylinder 41, and a bracket is provided inside the inner cylinder 41 to be rotatably connected to the end of the adjusting screw rod 415 away from the light source module 3, the outer wall of the adjusting screw rod 415 is provided with a threaded groove, and the inner slip ring 43 is provided with a threaded hole, and the threaded hole of the inner slip ring 43 is connected to the adjusting screw rod 41 5 is threadedly connected, the outer wall of the adjusting screw rod 415 is connected with an adjusting wheel 414, the adjusting wheel 414 is located in the installation groove of the light source module 3, the top of the adjusting wheel 414 is located outside the light source module 3, the adjusting wheel 414 is turned by hand, the adjusting wheel 414 drives the adjusting screw rod 415 to rotate, when the adjusting screw rod 415 rotates, the inner slip ring 43 is driven to slide left or right in the inner cylinder 41 through the cooperation between the thread groove above it and the threaded hole of the inner slip ring 43, so as to adjust the initial position of the No. 1 convex lens 44, at this time, a workpiece is used as a test, the staff rotates the adjusting wheel 414 back and forth, the light spot follows the rotation of the adjusting wheel 414 to adjust the size, when the light spot size is adjusted, stop rotating the adjusting wheel 414, close the housing 1, Carry out subsequent operations; through the setting of the adjustment device 4, the distance between the first convex lens 44 and the second convex lens 46 can be adjusted according to the width of different workpieces, so as to achieve the effect of adjusting the light spot size, so that the light spot presented on the smaller workpiece is larger, and the light spot presented on the larger workpiece is smaller, so that the light spot size always maintains a size suitable for light signal collection, reducing the need for workers to adjust the light spot size according to workpieces of different sizes, improving work efficiency and convenience; through the setting of the adjustment wheel 414 and the adjustment screw 415, the staff can adjust the initial size of the light spot by rotating the adjustment wheel 414, which is convenient for the staff to calibrate the light spot size, and further optimizes the applicability of the equipment. ,

[0036] For further information, see Figure 8 - Fig.12, the protective device 5 is used to protect the adjusting device 4. The protective device 5 includes a short shaft 51, which is rotatably mounted on the bottom of the fixed ring 45. The end of the short shaft 51 away from the No. 1 frame 6 is connected with a protective cover 52. In the initial state, the protective cover 52 coincides with the fixed ring 45. The protective cover 52 covers the outside of the No. 2 convex lens 46 to protect the No. 2 convex lens 46. The end of the short shaft 51 close to the No. 1 frame 6 is connected with a slide column 53. The No. 1 frame 6 is connected with a fixed frame 54. The fixed frame 54 is connected with a sliding shaft 55. The slide column 53 is provided with an arc groove and a straight groove. The arc groove and the straight groove of the slide column 53 are connected. The sliding shaft 55 is slidably connected with the arc groove and the straight groove of the slide column 53. The arc groove in the slide column 53 is located on the right side of the straight groove. In the initial position, the sliding shaft 55 When the slide bar 49 is reset, the slide column 53 moves to the left, the slide shaft 55 first contacts the straight groove and then contacts the arc groove, and when the arc groove slides along the slide shaft 55, it drives the short shaft 51 to rotate 180 degrees, so that the protective cover 52 is covered outside the second convex lens 46 again, thereby achieving the effect of the arc groove sliding along the slide shaft 55. When the workpiece is being inspected, the protective cover 52 is automatically opened and does not block the light. When the workpiece is not being inspected, the protective cover 52 is automatically closed to protect the No. 2 convex lens 46. The inner wall of the protective cover 52 is slidably mounted with a mounting plate 56 through a spring, and a cleaning cotton 57 is mounted on the mounting plate 56. The cleaning cotton 57 contacts the fixing ring 45 and the No. 2 convex lens 46 during movement. When the protective cover 52 moves, the cleaning cotton 57 on the mounting plate 56 inside it moves synchronously. Since the cleaning cotton 57 contacts the No. 2 convex lens 46, the cleaning cotton 57 can wipe the surface of the No. 2 convex lens 46 during movement to prevent dust from adhering to the surface of the No. 2 convex lens 46 and affecting the light transmission effect, thereby affecting the effect of light spot formation. A water tank 58 is mounted on the No. 1 frame 6. The water tank 58 is mounted on the No. 1 frame 6. 8 is filled with cleaning care liquid, an air bag 59 is installed on the top of the water tank 58, an atomizing nozzle 510 is installed on the side of the water tank 58 close to the cleaning cotton 57, and a slope block 511 is connected to the side of the slide bar 49 close to the cleaning cotton 57. The slope block 511 contacts the air bag 59 during the movement, and the slope block 511 contacts and squeezes the air bag 59 when following the slide bar 49 to reset. After the air bag 59 is squeezed, air is injected into the water tank 58. The water tank 58 uses the positive pressure to spray the cleaning care liquid inside it on the cleaning cotton 57 through the atomizing nozzle 510, so that a small amount of cleaning care liquid is attached to the cleaning cotton 57. The cleaning care liquid can improve the cleaning effect of the second convex lens 46, and play a certain maintenance role on the second convex lens 46, thereby extending the service life of the second convex lens 46;By setting the protection device 5, the protection cover 52 can automatically flip down and open when the workpiece is inspected, so that the light is projected onto the workpiece. When the workpiece inspection is completed, the protection cover 52 can automatically flip up and close to protect the second convex lens 46, so as to prevent the second convex lens 46 from being damaged by external force during use; by setting the cleaning cotton 57, the cleaning cotton 57 can wipe the surface of the second convex lens 46 during the opening and closing of the protection cover 52, so as to maintain the surface cleanliness of the second convex lens 46, thereby ensuring the imaging effect; by setting the water tank 58 and the atomizing nozzle 510, the atomizing nozzle 510 can spray the cleaning care liquid on the cleaning cotton 57, so as to improve the cleaning ability of the cleaning cotton 57, and at the same time play the role of maintaining the second convex lens 46, thereby extending the service life of the second convex lens 46. ;

[0037] With the above structure, the working principle of this case is that the staff installs the shell 1 beside the conveying line of the workpiece to be detected, so that the buffer plate 413 is located at the center line position of the conveying line, connects the photoelectric module 2 to the detection equipment through a wire, starts the photoelectric module 2 and the light source module 3, and the spotlight 9 on the light source module 3 emits light, and the light passes through the first convex lens 44, the second convex lens 46 and the light-transmitting port of the shell 1. When the workpiece passes through the conveying line, the light irradiates the workpiece to form a light spot, and the light spot produces diffuse reflection so that the light source module 3 captures the light signal generated by the diffuse reflection and transmits the light signal to the photoelectric module 2. The photoelectric module 2 converts the light signal into an electrical signal and transmits it to the detection equipment, thereby identifying the relevant parameters of the workpiece. The first convex lens 44 and the second convex lens 46 can adjust the size of the light spot formed on the workpiece by cooperating. Taking the light spot formed on the same light screen as a reference, the farther the distance between the first convex lens 44 and the second convex lens 46, the larger the light spot formed, and the closer the distance between the first convex lens 44 and the second convex lens 46, the smaller the light spot formed;The workpiece moves from back to front, and contacts the buffer plate 413 during the movement. The buffer plate 413 can provide a certain buffer to the workpiece to prevent the workpiece from being damaged. When the workpiece continues to move forward, the buffer plate 413 moves the rotating rod 412, so that the rotating rod 412 rotates around the mounting shaft 411. Since the two second frames 7 limit the sliding rod 49, the sliding rod 49 can only slide back and forth, so that the rotating rod 412 uses the lever principle to move the sliding rod 49 backward for a distance through the cooperation of the bearing and the slide groove. When the buffer plate 413 slides from the front side of the workpiece to the right side of the workpiece, the rotating rod 412 stops rotating, and the sliding rod 49 stops sliding. The slide bar 49 can move a corresponding distance according to the width of different workpieces. When the slide bar 49 moves, it drives the rack 410 to move synchronously. When the rack 410 moves, it drives the ball ring 47 to rotate through the gear ring 48. When the ball ring 47 rotates, the balls inside it slide along the thread groove on the outer cylinder 42, so that the balls apply a horizontal thrust to the thread groove, thereby achieving the effect that the ball ring 47 can drive the outer cylinder 42 to move to the right when it rotates. The outer cylinder 42 drives the second convex lens 46 to move towards the direction of the first convex lens 44 through the fixing ring 45, so that the distance between the first convex lens 44 and the second convex lens 46 is reduced. When the width of the workpiece is When the degree is large, since the sliding rod 49 moves a longer distance, the ball ring 47 drives the outer cylinder 42 to move to the right more by rotating. At this time, the light spot is reduced. Since the width of the workpiece is large, the distance between the workpiece and the spotlight 9 is short. By reducing the light spot, the light spot can be adjusted to a more suitable size, which is convenient for the light source module 3 to collect diffuse reflection light signals. On the contrary, when the workpiece is small, the ball ring 47 drives the outer cylinder 42 to move to the right less by rotating, and the reduction amplitude of the light spot is small. At this time, the light spot is large. Since the distance between the small workpiece and the spotlight 9 is far, the larger light spot is also convenient for the light source module 3 to collect diffuse reflection light signals. From the perspective of the light source module 3, the observed sizes of the smaller light spot close to the light source module 3 and the larger light spot far from the light source module 3 are similar, so that the light spots presented by the light on workpieces of different sizes are suitable for the light source module 3 to collect light signals, achieving the effect of adaptively adjusting the light spot size according to the size of the workpiece. When the buffer plate 413 is not in contact with the workpiece, the slide bar 49 is reset by the elastic force of the reset spring, and the slide bar 49 resets the rotating rod 412 when it is reset. When the rotating rod 412 is reset, it contacts the limit block 8, and the limit block 8 presses against the rotating rod 412 for limiting, so that the rotating rod 412 remains perpendicular to the left outer wall of the shell 1;Since the housing 1 may be installed next to conveyor lines of different specifications, and there is also the situation of replacing lenses of different specifications later, when the housing 1 is installed, if the size of the light spot presented on the workpiece does not meet the requirements, the staff can open the top of the housing 1 and turn the adjusting wheel 414 by hand. The adjusting wheel 414 drives the adjusting screw 415 to rotate. When the adjusting screw 415 rotates, the inner slip ring 43 is driven to slide left or right in the inner cylinder 41 through the cooperation between the threaded groove above it and the threaded hole of the inner slip ring 43, so as to adjust the initial position of the No. 1 convex lens 44. At this time, a workpiece is used as a test, and the staff rotates the adjusting wheel 414 back and forth. The light spot is adjusted in size following the rotation of the adjusting wheel 414. When the light spot size is adjusted, the adjusting wheel 414 is stopped. Close the housing 1 and carry out subsequent operations; through the setting of the adjustment device 4, the distance between the first convex lens 44 and the second convex lens 46 can be adjusted according to the width of different workpieces, so as to achieve the effect of adjusting the light spot size, so that the light spot presented on the smaller workpiece is larger, and the light spot presented on the larger workpiece is smaller, so that the light spot size always remains suitable for light signal collection, reducing the need for the staff to adjust the light spot size according to workpieces of different sizes, improving work efficiency and convenience; through the setting of the adjustment wheel 414 and the adjustment screw 415, the staff can adjust the initial size of the light spot by rotating the adjustment wheel 414, which is convenient for the staff to calibrate the light spot size and further optimizes the applicability of the equipment. ;

[0038] In the initial state, the protective cover 52 overlaps with the fixing ring 45, and the protective cover 52 covers the outside of the No. 2 convex lens 46 to protect the No. 2 convex lens 46. When the outer cylinder 42 moves to the right, the outer cylinder 42 drives the short shaft 51 to move to the right through the fixing ring 45, and the short shaft 51 drives the slide column 53 to move to the right. The arc groove in the slide column 53 is located on the right side of the straight groove. In the initial position, the slide shaft 55 is located at the rightmost end of the arc groove of the slide column 53. When the slide column 53 moves to the right, the arc groove slides along the slide shaft 55, so that the arc groove is subjected to the reverse thrust of the slide shaft 55 and drives the slide column 53 to rotate. When the slide column 53 rotates 180 degrees, the straight groove contacts the slide shaft 55, and the slide column 53 no longer rotates while continuing to move to the right. When the slide bar 49 is reset, the fixing ring 45 moves to the left. When the slide bar 49 moves to the left, the slide shaft 55 first contacts the straight groove and then the arc groove. When the arc groove slides along the slide shaft 55, the short shaft 51 is driven to rotate 180 degrees. The short shaft 51 drives the protective cover 52 to rotate, so that the protective cover 52 is covered outside the second convex lens 46 again, so that when the workpiece is detected, the protective cover 52 is automatically opened and does not block the light. When the workpiece is not detected, the protective cover 52 is automatically closed to protect the second convex lens 46. When the protective cover 52 moves, the internal arrangement The cleaning cotton 57 on the mounting plate 56 moves synchronously. Since the cleaning cotton 57 is in contact with the second convex lens 46, the cleaning cotton 57 can wipe the surface of the second convex lens 46 during the movement to prevent dust from adhering to the surface of the second convex lens 46 and affecting the light transmission effect, thereby affecting the effect of light spot formation; the water tank 58 is filled with cleaning care liquid, and the inclined plane block 511 moves synchronously with the slide bar 49. In the initial state, the inclined plane block 511 is pressed on the top of the airbag 59. After the slide bar 49 starts to move, the inclined plane block 511 leaves the top of the airbag 59, and the airbag 59 rebounds by its own elastic force. When the inspection of a workpiece is completed, the slide bar 49 starts to reset, so that the inclined plane block 511 contacts and squeezes the airbag 59 again when following the reset of the slide bar 49, and the airbag 59 After the capsule 59 is squeezed, air is injected into the water tank 58. The water tank 58 uses the positive pressure to spray the cleaning care liquid inside it onto the cleaning cotton 57 through the atomizing nozzle 510, so that a small amount of cleaning care liquid is attached to the cleaning cotton 57. The cleaning care liquid can improve the cleaning effect of the second convex lens 46, and play a certain maintenance role on the second convex lens 46, thereby extending the service life of the second convex lens 46; through the setting of the protective device 5, the protective cover 52 can automatically flip down and open when the workpiece is inspected, so that the light is projected onto the workpiece. When the workpiece inspection is completed, the protective cover 52 can automatically flip up and close to protect the second convex lens 46, so as to avoid the second convex lens 46 from being damaged due to external force collision during use;By setting the cleaning cotton 57, the cleaning cotton 57 can wipe the surface of the second convex lens 46 during the opening and closing of the protective cover 52, and maintain the surface cleanliness of the second convex lens 46, thereby ensuring the imaging effect; by setting the water tank 58 and the atomizing nozzle 510, the atomizing nozzle 510 can spray the cleaning care liquid on the cleaning cotton 57, thereby improving the cleaning ability of the cleaning cotton 57, and at the same time play the role of maintaining the second convex lens 46, thereby extending the service life of the second convex lens 46. ;
