Description

Technical Field

[0001] The present invention relates to the technical field of visual detection devices, and specifically to an automatic capillary visual detection device. Background Art

[0002] A capillary is a tube with an extremely fine inner diameter, usually referring to a thin tube with an inner diameter between a few micrometers and a few millimeters, including glass capillaries, plastic capillaries, stainless steel capillaries, etc. Among them, when producing stainless steel capillaries, a device using a visual system for detection is often borrowed. The image of the capillary is collected through an optical imaging system, and then image processing algorithms are used to analyze and process the image, so as to obtain information such as the size, shape, position, and surface defects of the capillary, in order to determine whether the capillary meets the quality standards.

[0003] When adding stainless steel capillaries to the vibrating bowl of the traditional detection device, in order to avoid problems such as excessive load on the vibration system caused by excessive accumulation of capillaries in the vibrating bowl or blockage at positions such as the material outlet, it is usually necessary for the operator to regularly and appropriately add capillaries to the vibrating bowl through a funnel. Furthermore, it is required that the operator repeatedly lift the capillary material from the ground and add it to the funnel. The operation process is cumbersome, resulting in low operation efficiency. And due to the limited space size of the discharge port on the funnel, it causes blockage of the capillaries at the outlet during feeding, and the practicability is poor; During the process of detecting stainless steel capillaries, usually the conveying track transports the capillaries one by one to the detection camera of the device and takes pictures of the capillaries, so as to convert the appearance information of the capillaries into digital image signals. And during the conveying process, in order to keep the stainless steel capillaries in a vertical state, the channel of the conveying track is usually set to a size corresponding to the outer diameter of the capillary. Therefore, when detecting capillaries of different specifications, it is necessary to repeatedly replace tracks of different sizes, and the operation process is cumbersome and the flexibility is poor; When the capillary completes the capture by the detection camera and is conveyed to the end of the conveying device, usually the sorting cylinder blows the qualified and unqualified capillaries into the two discharge ports of the device respectively, and at the same time drops them into the storage box directly below the discharge port. However, during the storage process in the storage box, due to the constant position of the discharge port, it causes the capillaries to pile up and stack high directly below the discharge port, resulting in uneven accumulation in the storage box, easily causing the capillaries to fall over and drop outside the storage box. And due to the high position of the discharge port, the capillaries are easily damaged due to collision during the process of falling into the storage box, and the practicability is poor.

Detailed implementation manners

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] Such as Figure 1 , Figure 5 , Figure 7 and Figures 9 - 12As shown in the figure, a capillary automatic vision detection device of the present invention includes an operation table 1, a conveying structure 3 installed on the operation table 1, an adjusting structure 4 connected to the conveying structure 3, a detection structure 5 installed on the operation table 1, a blanking structure 6 arranged on the side of the operation table 1, a feeding structure 7 installed on the operation table 1, and an opening and closing structure 8 cooperating with the feeding structure 7; the feeding structure 7 includes a mounting frame 701 and a connecting plate 702 fixedly connected to the center position of the mounting frame 701. The mounting frame 701 is fixedly connected to the operation table 1. Two guiding bars 703 are fixedly connected between the connecting plate 702 and the top end of the mounting frame 701. A discharge hopper 704 is slidably connected between the two guiding bars 703. The bottom end of the discharge hopper 704 is rotatably connected to a contact wheel 708. A third motor 706 is fixedly connected to the upper surface of the connecting plate 702. A cam 707 is fixedly connected to the output shaft of the third motor 706. The cam 707 abuts against the contact wheel 708. The top end of the discharge hopper 704 is fixedly connected to a docking port 709. A first storage hopper 710 is slidably connected to the top end of the mounting frame 701. The docking port 709 is slidably connected between the inner sides of the first storage hopper 710. Slide bars 712 are fixedly connected to both sides of the first storage hopper 710. The slide bars 712 are slidably connected to the mounting frame 701. A spring 713 is fixedly connected between the bottom of the slide bar 712 and the outer wall of the mounting frame 701. A second storage hopper 711 is fixedly connected to the inner side of the first storage hopper 710. A third tension spring 705 is fixedly connected between the discharge hopper 704 and the upper surface of the connecting plate 702. The second storage hopper 711 is located directly above the docking port 709. The mounting frame 701 is in a "U" - shaped structure. Inclined surfaces are provided at the inner bottoms of both the first storage hopper 710 and the second storage hopper 711. The opening and closing structure 8 is provided on the second storage hopper 711; when detecting features such as the inner diameter, size, and surface defects of stainless - steel capillaries, the capillaries are poured into the first storage hopper 710 from the top opening, so that the capillaries are stored inside the first storage hopper 710, which is convenient for subsequent quantitative and timed addition of capillaries to the vibrating disk 2, thus effectively avoiding the problems that the vibrating effect of the vibrating disk 2 is affected due to excessive accumulation of capillaries or blockage at the material outlet. Just turn on the power of the third motor 706. At this time, the third motor 706 drives the cam 707 on the output shaft to rotate a certain angle. During the process when the cam 707 rotates to a state flush with the connecting plate 702, the discharge hopper 704 slides downward along the two guiding bars 703 under the action of gravity and the pulling force of the third tension spring 705. The discharge hopper 704 drives the docking port 709 on the top surface to slide downward. At this time, since the first storage hopper 710 is fixed in position under the action of the springs 713 on both sides, during this process, the top surface of the docking port 709 no longer abuts against the bottom surface of the second storage hopper 711, and the distance between the top surface of the docking port 709 and the bottom surface of the second storage hopper 711 gradually increases.Until the top surface of the docking port 709 is flush with the bottom of the first storage hopper 710, the capillary tubes stored inside the first storage hopper 710 then fall from the central opening of the docking port 709 into the inside of the discharge hopper 704, and then roll from the discharge hopper 704 into the inside of the vibrating disk 2. At this time, the opening at the bottom of the first storage hopper 710 is opened and closed, facilitating the automatic rolling of the capillary tubes into the vibrating disk 2. When it is necessary to close the opening at the bottom of the first storage hopper 710, only need to drive the cam 707 to rotate in the reverse direction through the third motor 706. During the rotation of the cam 707, it will contact the contact wheel 708 on the discharge hopper 704, thereby driving the discharge hopper 704 and the docking port 709 to slide upward until the top surface of the docking port 709 contacts the bottom surface of the second storage hopper 711, thus closing the opening at the bottom of the first storage hopper 710. The operation is simple. At this time, the cam 707 has not completely rotated to a state perpendicular to the connecting plate 702, so the docking port 709 will not upwardly contact the first storage hopper 710, and the first storage hopper 710 remains stationary. If the capillary tubes inside the first storage hopper 710 are blocked and difficult to fall from the opening, only need to drive the cam 707 to continuously rotate 360 degrees through the third motor 706. When the cam 707 rotates to a state perpendicular to the connecting plate 702, the docking port 709 will upwardly contact the first storage hopper 710, driving the slide bars 712 on both sides of the first storage hopper 710 to compress the springs 713, and the first storage hopper 710 slides upward along the mounting frame 701. Thus, during the 360-degree rotation of the cam 707, the first storage hopper 710 is driven to repeatedly shake up and down, facilitating the shaking of the capillary tubes accumulated inside the first storage hopper 710 to be evenly distributed, effectively solving the problem of blockage at the opening at the bottom of the first storage hopper 710. At the same time, when the inside of the discharge hopper 704 is blocked, the cam 707 can also be rotated 360 degrees to drive the discharge hopper 704 to shake up and down, facilitating the blockage inside the discharge hopper 704 to slide into the vibrating disk 2. It has strong flexibility, effectively solving the problem of blockage of the capillary tubes at the opening of the first storage hopper 710 and inside the discharge hopper 704, and has strong practicability.

[0023] Specifically, such as Figure 1 、 Figure 5 、 Figure 9 、 Figure 10 and Figure 12As shown, the opening and closing structure 8 includes a pull rod 801 and a baffle 802 fixedly connected to the bottom of the pull rod 801. One end of the second storage hopper 711 is slidably connected to the pull rod 801, and the baffle 802 is slidably connected to the outer wall of the second storage hopper 711. A fourth tension spring 803 is fixedly connected between the top end of the pull rod 801 and the top surface of the second storage hopper 711. When it is necessary to detect capillary tubes of different specifications, another specification of capillary tube can be added to the inside of the second storage hopper 711. After all the capillary tubes of different specifications in the first storage hopper 710 are detected, only need to lift the pull rod 801 upward. The pull rod 801 drives the baffle 802 to slide upward until it no longer blocks the opening on the side wall of the second storage hopper 711. At this time, another specification of capillary tube inside the second storage hopper 711 rolls along the inclined surface at the inner bottom of the second storage hopper 711 into the inside of the first storage hopper 710, thus facilitating subsequent feeding into the vibrating disk 2, realizing the separation process of capillary tubes of different specifications, avoiding the mutual mixing of capillary tubes of different specifications, and since a fourth tension spring 803 is fixedly connected between the end of the pull rod 801 and the top surface of the second storage hopper 711, it effectively avoids the problem that the baffle 802 slides up and down driven by the up and down vibration of the first storage hopper 710, thus avoiding the capillary tubes of different specifications inside the second storage hopper 711 from rolling into the inside of the first storage hopper 710, with strong flexibility.

[0024] Specifically, such as Figures 1 - 7 and Figure 10As shown, the conveying structure 3 includes a first motor 301 and a glass turntable 302 fixedly connected to the output shaft of the first motor 301, the upper surface of the operating table 1 is fixedly connected to the first motor 301, the operating table 1 is fixedly connected to a vibration plate 2, the discharging trough of the vibration plate 2 is fixedly connected to a discharging guide rail 303, one end of the discharging guide rail 303 close to the first motor 301 is slidably connected to the glass turntable 302, the operating table 1 is fixedly connected to a support frame 304, both ends of the support frame 304 are rotatably connected to a rotating wheel 305, and the operating table 1 is fixedly connected to the first motor 301. A second motor 307 is fixedly connected to one end of the glass turntable 302, and the output shaft of the second motor 307 is fixedly connected to the rotating shaft of the adjacent rotating wheel 305. A conveyor belt 306 is wound between the two rotating wheels 305. The end of the discharge guide rail 303 is an arc-shaped structure, and the support frame 304 is equipped with an adjustment structure 4. The capillary tubes dropped into the vibration disk 2 are directed to move from the center to the edge of the vibration disk 2 along the spiral track under the action of vibration. At the same time, since a specific shape of the directional mechanism and the sorting device are set on the spiral track of the vibration disk 2, the capillary tubes are vertically moved. The capillary tube is oriented and moves from the discharge port to the discharge guide rail 303, and moves neatly and orderly along the discharge guide rail 303. Since the end of the discharge guide rail 303 is an arc-shaped structure, and there are multiple grooves arranged on the circumference of the glass turntable 302, when the groove is rotated to align with the opening of the end of the discharge guide rail 303, the capillary tube will move into the groove opened on the glass turntable 302, and the same operation will be repeated. Then, the glass turntable 302 drives the capillary tube above to make a circular motion. When the capillary tube passes the detection camera 501 at the bottom of the glass turntable 302, the detection camera 501 can see through the glass turntable 302. 02 Take a picture of the bottom of the capillary. At the same time, when the capillary moves to the arc-shaped guide piece 408, it will move vertically along the arc-shaped guide piece 408 to the thin sheet 405 between the two guide plates 404. Multiple capillaries repeat the same movement. When moving between the two guide plates 404, the capillary at the rear contacts the capillary in front and moves forward until it moves to the conveyor belt 306 on the support frame 304. The conveyor belt 306 drives the two rotating wheels 305 to rotate through the second motor 307 to achieve movement, which is conducive to driving the capillary for subsequent detection and sorting operations, and has strong flexibility.

[0025] Specifically, Figures 3 - 7As shown in the figure, the adjusting structure 4 includes an adjusting disc 401 and a nut 402 that abuts against the top surface of the adjusting disc 401. The adjusting disc 401 is rotatably connected to the upper surface of the glass turntable 302. The nut 402 is threadedly connected to the output shaft of the first motor 301. Two mounting blocks 403 are fixedly connected to one end of the support frame 304 close to the glass turntable 302. A guide plate 404 is slidably connected to the mounting block 403. A first tension spring 406 is fixedly connected between the guide plate 404 and the mounting block 403. A stop rod 407 is threadedly connected to the mounting block 403. The end of the stop rod 407 abuts against the guide plate 404. A thin plate 405 is fixedly connected to the bottom surface of one of the guide plates 404. A guide piece 408 is fixedly connected to one end of the other guide plate 404 close to the glass turntable 302. One end of the thin plate 405 is rotatably connected to the glass turntable 302. The other end of the thin plate 405 is flush with the horizontal part of the conveyor belt 306. The guide plate 404 is in a "T" - shaped structure. The guide piece 408 is in an arc - shaped structure; when conveying capillaries of different specifications, it is necessary to adjust the distance between the two guide plates 404 according to the outer diameter of the capillary. Just rotate the stop rods 407 on the two mounting blocks 403 simultaneously, so that the two stop rods 407 move the same distance outward. Under the pulling force of the first tension spring 406, the two guide plates 404 move in both sides' directions, thus effectively adjusting the distance between the two guide plates 404. Then rotate the nut 402 on the output shaft of the first motor 301, and then rotate the adjusting disc 401 on the glass turntable 302, so that the distance between the groove on the adjusting disc 401 and the corresponding groove on the glass turntable 302 is adjusted to a position corresponding to the outer diameter of the capillary, and then lock the nut 402, which is convenient for adapting to capillaries of different specifications and is easy to operate.

[0026] Specifically, such as Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 10As shown, the detection structure 5 includes five detection cameras 501 and three LED lights 502 disposed near the detection cameras 501. The upper surface of the operation table 1 is fixedly connected with the detection cameras 501. Two detection cameras 501 and one LED light 502 are respectively disposed on both sides of the support frame 304. Another detection camera 501 and another LED light 502 are disposed below the glass turntable 302. One condenser plate 503 is respectively disposed on both sides of the support frame 304. The condenser plate 503 is fixedly connected with the operation table 1. Two air nozzles 504 are fixedly connected to one end of the operation table 1 near the second motor 307. The two air nozzles 504 are disposed on the same side of the support frame 304. Two blanking bins 505 are disposed on the other side of the support frame 304. The blanking bins 505 are fixedly connected with the operation table 1. The capillary tubes conveyed by the conveyor belt 306 sequentially pass through the other detection cameras 501 on both sides of the support frame 304, so as to facilitate the detection of characteristics such as the size and surface defects of the capillary tubes. At the same time, the LED lights 502 cooperate with the condenser plates 503 to improve the photographing effect of the detection cameras 501. Finally, the detected capillary tubes are conveyed to the positions of the two air nozzles 504. The two air nozzles 504 respectively blow the qualified and unqualified capillary tubes on the conveyor belt 306 into the two blanking bins 505, and the detection efficiency is high.

[0027] Specifically, as Figure 1 , Figure 8 and Figure 10As shown, the unloading structure 6 includes two guide rods 601 and a load-bearing frame 602 slidably connected between the two guide rods 601, the two guide rods 601 are fixedly connected to the side wall of the operating table 1, a hydraulic rod 608 is fixedly connected between the bottom surface of the load-bearing frame 602 and the bottom of the operating table 1, and a fixed plate 603 is slidably connected to the end of the load-bearing frame 602 away from the guide rod 601, and a second tension spring 604 is fixedly connected between the fixed plate 603 and the outer wall of the load-bearing frame 602, and two storage boxes 605 are abutted on the load-bearing frame 602, and the fixed plate 603 abuts against the storage box 605. Two discharge pipes 606 are fixedly connected to the side of the operating table 1 close to the guide rods 601, and the end of the discharge pipe 606 is fixedly connected to a push plate 607; blow it down into the unloading bin 505 The capillaries at the bottom slide through the internal channel of the operating table 1 to the discharge pipe 606, and then fall from the discharge pipe 606 to the inside of the storage box 605 at the bottom, with strong flexibility, and the storage box 605 is clamped by the fixing plate 603 and the second tension spring 604, with strong firmness. At the same time, the hydraulic rod 608 located at the bottom of the load-bearing frame 602 can drive the load-bearing frame 602 to slide up and down along the guide rod 601, so as to facilitate the adjustment of the distance between the storage box 605 and the discharge pipe 606, and avoid the problem of the capillaries falling and being damaged. At the same time, when the capillaries are accumulated directly under the discharge pipe 606, the storage box 605 is driven by the hydraulic rod 608 to move upward until the push plate 607 located at the end of the discharge pipe 606 pushes the capillaries accumulated in the storage box 605 flat, which is easy to operate and avoids the problem of the capillaries accumulating and overflowing from the inside of the storage box 605.

[0028] When the present invention is in use, when detecting features such as the inner diameter, size, and surface defects of the stainless steel capillary, the capillary is poured from the top opening of the first storage hopper 710, and the capillary is stored inside the first storage hopper 710, which facilitates subsequent quantitative and timed addition of the capillary to the vibrating disc 2, thus effectively avoiding the problems that the vibrating effect of the vibrating disc 2 is affected due to excessive accumulation of the capillary or the material outlet is blocked. Just turn on the power of the third motor 706. At this time, the third motor 706 drives the cam 707 on the output shaft to rotate a certain angle. During the process of the cam 707 rotating to a state flush with the connecting plate 702, the discharge hopper 704 slides downward along the two guide bars 703 under the action of gravity and the pulling force of the third tension spring 705. The discharge hopper 704 drives the docking port 709 on the top surface to slide downward. At this time, since the first storage hopper 710 is fixed in position under the action of the springs 713 on both sides, and during this process, the top surface of the docking port 709 no longer abuts against the bottom surface of the second storage hopper 711, and the distance between the top surface of the docking port 709 and the bottom surface of the second storage hopper 711 gradually increases until the top surface of the docking port 709 is flush with the horizontal position at the bottom of the first storage hopper 710. Then, the capillary stored inside the first storage hopper 710 falls from the central opening of the docking port 709 into the inside of the discharge hopper 704, and then rolls from the discharge hopper 704 into the inside of the vibrating disc 2. At this time, the opening at the bottom of the first storage hopper 710 is opened and closed, which facilitates the automatic rolling of the capillary into the vibrating disc 2. When it is necessary to close the opening at the bottom of the first storage hopper 710, just drive the cam 707 to rotate in the reverse direction through the third motor 706. During the rotation of the cam 707, it will abut against the abutting wheel 708 on the discharge hopper 704, thereby driving the discharge hopper 704 and the docking port 709 to slide upward until the top surface of the docking port 709 abuts against the bottom surface of the second storage hopper 711, thus closing the opening at the bottom of the first storage hopper 710. The operation is simple. At this time, the cam 707 has not completely rotated to a state perpendicular to the connecting plate 702, so the docking port 709 will not abut against the first storage hopper 710 upward, and the first storage hopper 710 remains stationary. If the capillary inside the first storage hopper 710 is blocked and difficult to fall from the opening, just drive the cam 707 to continuously rotate 360 degrees through the third motor 706. When the cam 707 rotates to a state perpendicular to the connecting plate 702, the docking port 709 will abut against the first storage hopper 710 upward, driving the slide bars 712 on both sides of the first storage hopper 710 to compress the springs 713, and the first storage hopper 710 slides upward along the mounting frame 701. Then, during the 360-degree rotation of the cam 707, the first storage hopper 710 is driven to shake up and down repeatedly, so as to facilitate the shaking of the accumulated capillary inside the first storage hopper 710 to be evenly distributed, effectively solving the problem of blockage at the opening at the bottom of the first storage hopper 710. At the same time, when the inside of the discharge hopper 704 is blocked, the cam 707 can also be rotated 360 degrees to drive the discharge hopper 704 to shake up and down.It is convenient to block the capillary from sliding into the vibrating disk 2 inside the discharge hopper 704, with strong flexibility, effectively solving the problem of capillary blockage at the opening of the first storage hopper 710 and inside the discharge hopper 704, and having strong practicability; When it is necessary to detect capillaries of different specifications, another specification of capillary can be added to the inside of the second storage hopper 711. After all the capillaries of different specifications in the first storage hopper 710 are detected, only need to lift the pull rod 801 upward. The pull rod 801 drives the baffle 802 to slide upward until it no longer blocks the opening on the side wall of the second storage hopper 711. At this time, another specification of capillary inside the second storage hopper 711 will roll along the inclined plane at the inner bottom of the second storage hopper 711 into the inside of the first storage hopper 710, so as to facilitate subsequent feeding into the vibrating disk 2, realizing the separation of capillaries of different specifications, avoiding the mutual mixing of capillaries of different specifications, and since a fourth tension spring 803 is fixedly connected between the end of the pull rod 801 and the top surface of the second storage hopper 711, it effectively avoids the problem that the baffle 802 slides up and down driven by the up and down vibration of the first storage hopper 710, thus avoiding the capillaries of different specifications inside the second storage hopper 711 from rolling into the inside of the first storage hopper 710, with strong flexibility; The capillary tubes that fall into the vibrating bowl 2 move directionally along the spiral track from the center of the vibrating bowl 2 to the edge under the action of vibration. At the same time, due to the specific-shaped orientation mechanism and sorting device provided on the spiral track of the vibrating bowl 2, the capillary tubes are vertically oriented and move from the discharge port to the discharge guide rail 303, and move neatly and orderly along the discharge guide rail 303. Since the end of the discharge guide rail 303 is an arc-shaped structure, and there are multiple grooves arranged in a circle on the glass turntable 302, when the groove rotates to align with the opening at the end of the discharge guide rail 303, the capillary tubes will move into the grooves opened on the glass turntable 302. By repeating the same operation, the glass turntable 302 drives the capillary tubes above to perform a circular motion. When the capillary tubes pass by the detection camera 501 at the bottom of the glass turntable 302, the detection camera 501 can take pictures of the bottom of the capillary tubes through the glass turntable 302. At the same time, when the capillary tubes move to the arc-shaped guide piece 408, they will move vertically along the arc-shaped guide piece 408 to the thin sheet 405 between the two guide plates 404. Multiple capillary tubes repeat the same movement. When moving between the two guide plates 404, the capillary tubes located at the back will push the capillary tubes in front to move forward until they move onto the conveyor belt 306 on the support frame 304. The conveyor belt 306 is driven by the second motor 307 to rotate the two runners 305 to achieve movement, which is conducive to driving the capillary tubes for subsequent detection and sorting operations, with strong flexibility. The capillary tubes conveyed by the conveyor belt 306 pass by the other detection cameras 501 on both sides of the support frame 304 in turn, so as to facilitate the detection of the characteristics of the capillary tubes such as size and surface defects. At the same time, the LED lamp 502 cooperates with the condenser plate 503 to improve the photographing effect of the detection camera 501. Finally, the detected capillary tubes are conveyed to the positions of the two air nozzles 504, and the two air nozzles 504 blow the qualified and unqualified capillary tubes on the conveyor belt 306 into the two discharge bins 505 respectively, with high detection efficiency; When conveying capillary tubes of different specifications, it is necessary to adjust the distance between the two guide plates 404 according to the outer diameter of the capillary tubes. Just rotate the stop bars 407 on the two mounting blocks 403 at the same time to make the two stop bars 407 move the same distance outward. Under the pulling force of the first tension spring 406, the two guide plates 404 move in both directions, effectively adjusting the distance between the two guide plates 404. Then rotate the nut 402 on the output shaft of the first motor 301, and then rotate the adjustment disk 401 on the glass turntable 302 to adjust the distance between the groove on the adjustment disk 401 and the corresponding groove on the glass turntable 302 to a position that matches the outer diameter of the capillary tubes, and then lock the nut 402 to facilitate adapting to capillary tubes of different specifications, with simple operation; The capillary tubes blown into the interior of the blanking bin 505 slide down through the internal channel of the operating platform 1 to the discharge pipe 606, and then fall from the discharge pipe 606 into the interior of the storage box 605 at the bottom. It has strong flexibility. Moreover, the storage box 605 is clamped by the fixing plate 603 in cooperation with the second tension spring 604, so it has strong firmness. At the same time, the hydraulic rod 608 at the bottom of the load-bearing frame 602 can drive the load-bearing frame 602 to slide up and down along the guide rod 601, thereby facilitating the adjustment of the distance between the storage box 605 and the discharge pipe 606, avoiding the problem of capillary tubes being damaged by falling. Also, when the capillary tubes accumulate directly below the discharge pipe 606, the hydraulic rod 608 drives the storage box 605 to move upward until the push plate 607 at the end of the discharge pipe 606 levels the capillary tubes accumulated in the storage box 605. The operation is simple, avoiding the problem of capillary tubes overflowing from the interior of the storage box 605 due to accumulation.
