Description

Technical Field

[0001] This application relates to the field of vision detection devices, and particularly to a tape vision detection device. Background Art

[0002] A vision detection device is a device that uses machine vision technology for automated detection. It is widely used in various industrial fields for product quality inspection, defect identification, and dimension measurement, etc.

[0003] In related technologies, vision detection devices are also required for quality inspection of tapes during daily processing and production. Specifically, after the tape is processed, it is conveyed by a conveyor belt to the next process for encapsulation. When the tape is conveyed on the conveyor belt, a corresponding camera is used to identify the tape to confirm whether there are quality defects, so as to effectively avoid encapsulating defective tapes.

[0004] Conventional tapes are divided into two categories, one is a flat tape and the other is a three-dimensional tape.

[0005] The flat tape is sheet-like and relatively thin. When this type of tape is identified by a camera, only one camera needs to be set directly above the flat tape, and the top of the flat tape is identified by this camera to check for defects, without the need to identify defects on the left and right sides of the flat tape.

[0006] The three-dimensional tape is integrally ring-shaped and has a small volume. During its transportation, it is transported independently one by one. That is, after one three-dimensional tape is transported, the next three-dimensional tape is transported. During its specific transportation process, it is necessary to identify not only the top of the three-dimensional tape but also the left and right sides of the three-dimensional tape. The conventional method is to use two cameras for identification. One camera is used to identify the top of the three-dimensional tape, and the other camera is used to identify the side of the three-dimensional tape.

[0007] However, the camera for identifying the side of the three-dimensional tape is usually fixed to the chassis through a corresponding mounting bracket, which makes the shooting angle of this camera fixed, resulting in the problem of a single shooting angle. At the same time, to ensure the forming quality of the three-dimensional tape, it is necessary to identify the left and right sides of the three-dimensional tape during transportation. This makes it necessary for the camera to move from one side of the three-dimensional tape to the other side when identifying the three-dimensional tape. Most cameras are fixed inside the chassis, which makes the camera can only identify one side of the three-dimensional tape and cannot move to the other side of the three-dimensional tape for identification, thus resulting in the problem of incomplete identification of the three-dimensional tape, which is not conducive to the daily processing and production of the three-dimensional tape. Summary of the Invention

[0008] The present application provides a visual inspection device for a strip, aiming to conduct more comprehensive defect identification on a three-dimensional strip during the conveying process, thereby facilitating the daily processing and production of the three-dimensional strip and further avoiding the encapsulation of defective three-dimensional strips.

[0009] The present application provides a visual inspection device for a strip, adopting the following technical solution:

[0010] A visual inspection device for a strip includes a chassis. Inside the chassis, a conveyor belt is installed horizontally. Both the left and right ends of the conveyor belt extend out of the chassis. On both sides of the conveyor belt, limiting plates are installed vertically. Inside the chassis, a first camera and a second camera are provided. The first camera and the second camera are arranged at intervals. The first camera and the second camera are both slidably arranged on the top of the chassis, and an adjusting component is additionally arranged inside the chassis. The adjusting component is used to drive the second camera to rotate during the sliding process.

[0011] By adopting the above technical solution, when a flat strip is conveyed into the chassis, only the first camera operates. After the flat strip is conveyed into the interior of the chassis, in this state, the first camera is fixed on the top of the chassis and remains stationary. When the flat strip passes below the first camera during the conveying process, the first camera identifies defects on the top of the flat strip.

[0012] When a three-dimensional strip is conveyed into the chassis, the first camera and the second camera operate simultaneously. Both the first camera and the second camera slide along with the three-dimensional strip. The first camera identifies the top of the three-dimensional strip. During the forward sliding process of the second camera, it can also swing left and right simultaneously, that is, the second camera can gradually transfer from the left side of the three-dimensional strip to the right side during the sliding process. Thus, after the three-dimensional strip enters the chassis, the first camera and the second camera can conduct comprehensive defect identification and detection on the three-dimensional strip.

[0013] With this setting method, the first camera and the second camera can conduct more comprehensive defect identification on the three-dimensional strip during the conveying process, thereby facilitating the daily processing and production of the three-dimensional strip and further avoiding the encapsulation of defective three-dimensional strips.

[0014] Preferably, a first motor is fixed on the side wall of the chassis. At the driving end of the first motor, a lead screw is installed horizontally. A sliding seat is fixed on the top of the first camera. The lead screw penetrates through the sliding seat and is in threaded cooperation with the sliding seat.

[0015] By adopting the above technical solution, when the strip enters the chassis, the first motor is turned on. While the first motor drives the lead screw to rotate, it simultaneously drives the sliding seat and the first camera to slide along the length direction of the lead screw. The first motor is a reversible motor. When the strip finishes running inside the chassis, the first motor drives the first camera to reset.

[0016] Preferably, an arc-shaped adjusting plate is provided inside the chassis. The adjusting assembly is arranged on the adjusting plate. The second camera is installed on the adjusting plate. The top of the adjusting plate is connected with an independent connecting plate through a spring. Connection holes are respectively opened at the left and right ends of the side of the connecting plate close to the sliding seat. Connecting rods are respectively fixed horizontally at the left and right ends of the side of the sliding seat close to the connecting plate. The two connecting rods correspond to the two connection holes one by one. The two connection holes and the two connecting rods are used to connect the sliding seat and the adjusting plate.

[0017] By adopting the above technical solution, when the three-dimensional strip is conveyed on the conveyor belt, first, the first motor is used to drive the sliding seat to slide towards the direction close to the connecting plate until the two connecting rods are respectively inserted into the two connection holes, and the sliding seat and the connecting plate are connected by the two connecting rods and the two connection holes. After the connection between the sliding seat and the connecting plate is completed, the first motor is used to drive the sliding seat to move forward. During the forward movement of the sliding seat, the connecting plate, the adjusting plate and the second camera are simultaneously driven to slide. During the forward movement of the second camera, it gradually transfers from the left side of the three-dimensional strip to the right side of the three-dimensional strip, so as to complete the all-round recognition of the three-dimensional strip through the first camera and the second camera.

[0018] Preferably, the adjusting assembly includes a driving cylinder, a first driving rod, a second driving rod and a third driving rod. An installation groove is horizontally opened on the side of the adjusting plate close to the sliding seat. The driving cylinder is fastened in the installation groove. A moving seat is integrally connected to the piston rod of the driving cylinder. A hinged rod is fixed on the moving seat. One end of the first driving rod is hinged to the moving seat through the hinged rod, and the other end of the first driving rod far from the moving seat is hinged to the side wall of the second driving rod through a corresponding hinged rod. A hinged seat is integrally connected to the bottom of the adjusting plate through a corresponding connecting rod. The bottom of the second driving rod is hinged to the hinged seat through a hinged rod. The top of the second driving rod is connected to the third driving rod through a corresponding connecting rod. The bottom of the third driving rod is integrally connected to the second camera.

[0019] By adopting the above technical solution, when the second camera rotates specifically, the driving cylinder drives the moving seat to slide in the installation groove. During the sliding process of the moving seat, it is hinged to the first driving rod, and then drives the first driving rod to rotate through the moving seat. When the first driving rod rotates, it synchronously drives the second driving rod to rotate. While the second driving rod rotates, it drives the second camera to rotate through the third driving rod, so that the second camera can be transferred from the left side of the three-dimensional tape to the right side of the three-dimensional tape.

[0020] Preferably, an arc-shaped first adjustment groove is formed on one side of the adjustment plate close to the sliding seat. The first adjustment groove is located above the installation groove. A telescopic assembly is added in the first adjustment groove. The telescopic assembly is slidably arranged in the first adjustment groove. The top of the third driving rod is connected to the telescopic assembly. The telescopic assembly is used to drive the third driving rod and the second camera to expand and contract during the rotation process.

[0021] By adopting the above technical solution, when the driving cylinder drives the first driving rod, the second driving rod and the third driving rod to rotate, it synchronously drives the telescopic assembly to rotate in the first adjustment groove. While the telescopic assembly slides in the first adjustment groove, it can expand and contract.

[0022] During the process of the second camera being transferred from the left side to the right side of the three-dimensional tape:

[0023] When the second camera is transferred from the left side of the three-dimensional tape to the uppermost part of the three-dimensional tape, since the rotation trajectory of the second camera is arc-shaped, the distance between the second camera and the three-dimensional tape gradually decreases during this process. In this state, the telescopic assembly drives the second camera to contract in a direction away from the three-dimensional tape;

[0024] When the second camera is transferred from the uppermost part of the three-dimensional tape to the right side of the three-dimensional tape, the distance between the second camera and the three-dimensional tape gradually increases during this process. In this state, the telescopic assembly drives the second camera to extend in a direction close to the three-dimensional tape.

[0025] Furthermore, through the telescopic assembly, the distance between the second camera and the three-dimensional tape can be effectively kept appropriate, and the situation that the distance between the second camera and the three-dimensional tape is too far or too close will not occur. Therefore, it is beneficial to ensure the clarity of the shooting of the three-dimensional tape by the second camera.

[0026] Preferably, the telescopic assembly includes a telescopic toothed ring and a first gear. The telescopic toothed ring is located in the first adjustment groove. The first gear is rotatably installed in the telescopic toothed ring and is meshed with the telescopic toothed ring. The first gear is used to drive the telescopic toothed ring to expand and contract. The top of the third driving rod is connected to the side wall of the telescopic toothed ring;

[0027] The telescopic gear ring is integrally annular, and both its left and right inner sides are tooth-shaped. Half of the first gear is tooth-shaped and the other half is smooth;

[0028] A movable hole is formed through the side wall of the third driving rod, and the hinge rod between the second driving rod and the third driving rod is inserted into the movable hole.

[0029] By adopting the above technical solution, when the third driving rod expands and contracts driven by the telescopic gear ring, the movable hole provides corresponding expansion and contraction space for the expansion and contraction of the third driving rod. During the rotation of the first gear, it meshes with the telescopic gear ring and drives the telescopic gear ring to expand and contract. During the expansion and contraction of the telescopic gear ring, it drives the third driving rod to expand and contract, and further drives the second camera to expand and contract through the third driving rod.

[0030] When the second camera moves from the left side of the three-dimensional tape to the uppermost part of the three-dimensional tape, during this process, the first gear meshes with the teeth on the right side of the telescopic gear ring. In this state, the telescopic gear ring contracts driven by the first gear, and further drives the third driving rod and the second camera to contract synchronously through the telescopic gear ring;

[0031] When the second camera moves from the uppermost part of the three-dimensional tape to the right side of the three-dimensional tape, during this process, the first gear meshes with the teeth on the left side of the telescopic gear ring. In this state, the telescopic gear ring extends driven by the first gear, and further drives the third driving rod and the second camera to extend synchronously through the telescopic gear ring.

[0032] Furthermore, through the telescopic assembly, the distance between the second camera and the three-dimensional tape can be effectively kept appropriate, and the situation that the distance between the second camera and the three-dimensional tape is too far or too close will not occur, which is beneficial to ensuring the clarity of the shooting of the three-dimensional tape by the second camera.

[0033] Preferably, a second adjustment groove is formed through the bottom of the first adjustment groove along its opening direction. A second motor is installed on the side of the adjustment plate away from the telescopic gear ring. The second motor is slidably arranged along the opening direction of the second adjustment groove. A first rotating shaft is installed at the driving end of the second motor. One end of the first rotating shaft away from the second motor penetrates through the second adjustment groove and is connected to the axis of the first gear. The second motor drives the first gear to rotate within the telescopic gear ring through the first rotating shaft.

[0034] By adopting the above technical solution, when the driving cylinder drives the telescopic gear ring to rotate in the first adjustment groove through the first driving rod, the second driving rod and the third driving rod, the first gear synchronously drives the second motor and the first rotating shaft to rotate in the second adjustment groove.

[0035] Preferably, an installation box is fixed on the inner wall of the chassis, and an auxiliary component is additionally arranged in the installation box, and the auxiliary component is used to drive the adjusting plate to rotate;

[0036] The auxiliary component includes a third motor, a second gear, a rack and two auxiliary rods; the third motor is fastened in the installation box, a second rotating shaft is vertically installed at the driving end of the third motor, the second gear is horizontally connected to the second rotating shaft, the rack is horizontally arranged, the rack is meshed and connected with the second gear, the third motor drives the second gear to rotate, and the second gear drives the rack to slide horizontally;

[0037] Both the left and right ends of the rack are wedge-shaped, and the bottoms of the two auxiliary rods are both wedge-shaped. The bottoms of the two auxiliary rods are respectively in wedge-shaped fit with the left and right ends of the rack. During the sliding process of the rack, the two auxiliary rods are driven to move up and down;

[0038] Two movable blocks are installed on one side of the adjusting plate close to the third motor, and telescopic rods are installed between the two auxiliary rods and the side wall of the adjusting plate. One end of the telescopic rod is connected to the corresponding auxiliary rod, and the other end of the telescopic rod extends into the corresponding movable block. While the two auxiliary rods move up and down, the telescopic rods move up and down in the corresponding movable blocks.

[0039] By adopting the above technical solution, since the bottom of the adjusting plate is connected to the hinge seat through the corresponding connecting rod, when the two telescopic rods move up and down, the adjusting plate is driven to rotate. During the rotation of the adjusting plate, it assists the rotation of the third motor and the telescopic gear ring to a certain extent, which is beneficial to improving the stability of the third motor and the telescopic gear ring during the rotation process.

[0040] To sum up, the present application includes at least one of the following beneficial technical effects:

[0041] 1. When the flat strip is conveyed into the chassis, only the first camera operates. After the flat strip is conveyed into the interior of the chassis, in this state, the first camera is fixed on the top of the chassis and remains stationary. When the flat strip passes under the first camera during the conveying process, the top of the flat strip is defect-identified by the first camera.

[0042] After the three-dimensional tape is conveyed into the chassis, the first camera and the second camera operate simultaneously. Both the first camera and the second camera slide along with the three-dimensional tape. The first camera identifies the top of the three-dimensional tape. During the forward sliding process, the second camera can also swing left and right, that is, the second camera can gradually move from the left side of the three-dimensional tape to the right side during the sliding process. Thus, after the three-dimensional tape enters the chassis, the first camera and the second camera can conduct a comprehensive defect identification and detection on the three-dimensional tape.

[0043] With this setting method, the first camera and the second camera can conduct a more comprehensive defect identification on the three-dimensional tape during the conveying process, which is beneficial to ensuring the daily processing and production of the three-dimensional tape and can further prevent the packaging of defective three-dimensional tapes.

[0044] 2. The telescopic assembly can effectively keep the distance between the second camera and the three-dimensional tape appropriate at all times, and there will be no situation where the distance between the second camera and the three-dimensional tape is too far or too close, which is beneficial to ensuring the clarity of the second camera's shooting of the three-dimensional tape.

[0045] 3. Since the bottom of the adjusting plate is connected to the hinge seat through corresponding connecting rods, when the two telescopic rods rise and fall, the adjusting plate is driven to rotate. During the rotation of the adjusting plate, it provides certain assistance to the rotation of the third motor and the telescopic gear ring, which is beneficial to improving the stability of the rotation of the third motor and the telescopic gear ring.

Detailed implementation manners

[0053] The following will further describe the present application in detail with reference to the attached Figure 1 - attached Figure 6 drawings.

[0054] Embodiment:

[0055] An embodiment of the present application discloses a strip vision inspection device. Referring to Figure 1 and Figure 2 , it includes a chassis 1 which is in a cuboid shape and has a hollow interior. A conveyor belt 2 is installed horizontally inside the chassis 1, and both the left and right ends of the conveyor belt 2 extend out of the chassis 1. Limiting plates 3 are installed vertically on both the left and right sides of the conveyor belt 2. At the same time, a first camera 4 and a second camera 5 are provided inside the chassis 1. The first camera 4 and the second camera 5 are both slidably arranged on the top of the chassis 1, and the second camera 5 can rotate while sliding. The first camera 4 and the second camera 5 are arranged at intervals. Along the conveying direction of the conveyor belt 2, the first camera 4 is in the front and the second camera 5 is in the rear. The distance between the first camera 4 and the second camera 5 can be adjusted according to the specific size of the strip, so as to ensure that both the first camera 4 and the second camera 5 can clearly take pictures and identify the strip.

[0056] When specifically inspecting the strip, the strip is transported to the inside of the chassis 1 through the conveyor belt 2 for defect identification. During the transportation of the strip on the conveyor belt 2, the limiting plates 3 on both sides of the conveyor belt 2 limit the strip, and the strip is prevented from falling off the conveyor belt 2 through the limiting plates 3. The distance between the two limiting plates 3 and the width of the conveyor belt 2 can both be adjusted to adapt to strips of different sizes.

[0057] After the flat strip is conveyed into the chassis 1, only the first camera 4 operates. After the flat strip is conveyed into the interior of the chassis 1, in this state, the first camera 4 is fixed on the top of the chassis 1 and remains stationary. When the flat strip passes under the first camera 4 during the conveying process, the first camera 4 is used to identify defects on the top of the flat strip.

[0058] After the three-dimensional strip is conveyed into the chassis 1, the first camera 4 and the second camera 5 operate simultaneously. Both the first camera 4 and the second camera 5 slide along with the three-dimensional strip. The first camera 4 identifies the top of the three-dimensional strip. During the forward sliding process, the second camera 5 can also swing left and right, that is, the second camera 5 can gradually move from the left side of the three-dimensional strip to the right side during the sliding process. Then, after the three-dimensional strip enters the chassis 1, the first camera 4 and the second camera 5 can perform comprehensive defect identification and detection on the three-dimensional strip.

[0059] With this setting method, the first camera 4 and the second camera 5 can perform more comprehensive defect identification on the three-dimensional strip during the conveying process, which is beneficial to ensuring the daily processing and production of the three-dimensional strip and can further prevent the packaging of defective three-dimensional strips.

[0060] The initial position of the second camera 5 is on one side of the three-dimensional strip, either the left or the right side. In this embodiment, the initial position of the second camera 5 is on the left side of the three-dimensional strip. After the three-dimensional strip enters the chassis 1, the second camera 5 starts to slide along with the three-dimensional strip, while identifying one side of the three-dimensional strip and gradually rotating towards the other side of the three-dimensional strip. When the three-dimensional strip is conveyed to the outlet of the chassis 1, the second camera 5 moves to the other side of the three-dimensional strip to complete the identification of the other side of the three-dimensional strip.

[0061] Specifically, referring to Figure 1 and Figure 2 , a first motor 7 is fixedly installed on the side wall of the chassis 1 through fastening bolts. A lead screw 8 is installed horizontally at the driving end of the first motor 7. The top of the first camera 4 is connected to a sliding seat 9 through a corresponding connecting rod. The lead screw 8 passes through the sliding seat 9 and is in threaded cooperation with the sliding seat 9. After the three-dimensional strip enters the chassis 1, the first motor 7 is turned on. While the first motor 7 drives the lead screw 8 to rotate, it simultaneously drives the sliding seat 9 and the first camera 4 to slide along the length direction of the lead screw 8. The first motor 7 is a reversible motor. When the strip finishes moving in the chassis 1, the first motor 7 drives the first camera 4 to reset.

[0062] At the same time, referring to Figure 1 and Figure 2, inside the chassis 1, there is an arc-shaped adjusting plate 10, and the second camera 5 is installed on the adjusting plate 10. The adjusting plate 10 is vertically arranged, and the top of the adjusting plate 10 is connected with an independent connecting plate 11 through a spring. Circular connecting holes 12 are opened at the left and right ends of the connecting plate 11 close to the sliding seat 9. At the left and right ends of the sliding seat 9 close to the connecting plate 11, connecting rods 13 are welded along the horizontal direction. The two connecting rods 13 correspond to the two connecting holes 12 one by one. When the three-dimensional strip is conveyed on the conveyor belt 2, first, the first motor 7 is used to drive the sliding seat 9 to slide towards the connecting plate 11 until the two connecting rods 13 are respectively inserted into the two connecting holes 12, and the sliding seat 9 and the connecting plate 11 are connected by the two connecting rods 13 and the two connecting holes 12. After the sliding seat 9 and the connecting plate 11 are connected, the first motor 7 is used to drive the sliding seat 9 to move forward. During the forward movement of the sliding seat 9, the connecting plate 11, the adjusting plate 10, and the second camera 5 are synchronously driven to slide. During the forward movement of the second camera 5, it gradually moves from the left side of the three-dimensional strip to the right side of the three-dimensional strip, and then the full aspect recognition of the three-dimensional strip is completed by the first camera 4 and the second camera 5.

[0063] A rubber pad is embedded in the inner wall of the connecting hole 12. The rubber pad has elasticity. After the connecting rod 13 is inserted into the connecting hole 12, the rubber pad can clamp the connecting rod 13. At the same time, the rubber pad can increase the friction with the connecting rod 13, which is beneficial to ensuring the stability of the connection between the sliding seat 9 and the connecting plate 11. When it is necessary to separate the sliding seat 9 and the connecting plate 11, the connecting plate 11 is manually limited, and the sliding seat 9 slides forward so that the connecting rod 13 slides out of the corresponding connecting hole 12.

[0064] In the actual production process, when the strip is subjected to visual recognition, it often needs to be reported in advance. For example, if today is the recognition of a flat strip, the workshop staff can separate the sliding seat 9 and the connecting plate 11 in advance. After the flat strip enters the chassis 1, only the first camera 4 needs to operate. If today is the recognition of a three-dimensional strip, the workshop staff can connect the sliding seat 9 and the connecting plate 11 in advance, and the first camera 4 and the second camera 5 are used to simultaneously perform full aspect defect recognition on the three-dimensional strip. Therefore, the installation and disassembly between the sliding seat 9 and the connecting plate 11 do not need to be carried out frequently.

[0065] Refer to Figure 2 and Figure 3 , on the adjusting plate 10, there is an adjusting component 6, and the adjusting component 6 is used to adjust the second camera 5 from the left side of the three-dimensional strip to the right side of the three-dimensional strip.

[0066] Specifically, refer to Figure 2 and Figure 3, the adjusting assembly 6 includes a driving cylinder 61, a first driving rod 62, a second driving rod 63 and a third driving rod 64. A long strip-shaped installation groove 14 is formed in a horizontal direction on the side of the adjusting plate 10 close to the sliding seat 9, and the driving cylinder 61 is fastened into the installation groove 14 through corresponding fastening bolts. A moving seat 15 is integrally connected to the piston rod of the driving cylinder 61, and a hinged rod is welded on the moving seat 15. One end of the first driving rod 62 is hinged to the moving seat 15 through the hinged rod, and the other end of the first driving rod 62 away from the moving seat 15 is hinged to the side wall of the second driving rod 63 through a corresponding hinged rod. The bottom of the adjusting plate 10 is integrally connected with a hinge seat 16 through a corresponding connecting rod, the bottom of the second driving rod 63 is hinged to the hinge seat 16 through a hinged rod, and the top of the second driving rod 63 is connected to the third driving rod 64 through a corresponding connecting rod. The bottom of the third driving rod 64 is integrally connected with the second camera 5.

[0067] When the second camera 5 is specifically rotating, the driving cylinder 61 drives the moving seat 15 to slide in the installation groove 14. During the sliding process of the moving seat 15, it is hinged to the first driving rod 62, and then the first driving rod 62 is driven to rotate by the moving seat 15. When the first driving rod 62 rotates, it synchronously drives the second driving rod 63 to rotate. While the second driving rod 63 is rotating, it drives the second camera 5 to rotate through the third driving rod 64, so that the second camera 5 can be transferred from the left side of the three-dimensional material belt to the right side of the three-dimensional material belt.

[0068] Further, referring to Figure 2 , Figure 3 and Figure 4 , an arc-shaped first adjusting groove 17 is formed on the side of the adjusting plate 10 close to the sliding seat 9, and the first adjusting groove 17 is located above the installation groove 14. A telescopic assembly 18 is arranged in the first adjusting groove 17, the telescopic assembly 18 is slidably arranged in the first adjusting groove 17, the top of the third driving rod 64 is connected to the telescopic assembly 18, and the telescopic assembly 18 is used to drive the third driving rod 64 and the second camera 5 to expand and contract during the rotation process. When the driving cylinder 61 drives the first driving rod 62, the second driving rod 63 and the third driving rod 64 to rotate, it synchronously drives the telescopic assembly 18 to rotate in the first adjusting groove 17. While the telescopic assembly 18 slides in the first adjusting groove 17, it can expand and contract.

[0069] During the process of the second camera 5 being transferred from the left side to the right side of the three-dimensional material belt:

[0070] When the second camera 5 is transferred from the left side to the uppermost part of the three-dimensional material belt, since the rotation trajectory of the second camera 5 is arc-shaped, the distance between the second camera 5 and the three-dimensional material belt gradually decreases during this process. In this state, the telescopic assembly 18 drives the second camera 5 to contract in a direction away from the three-dimensional material belt;

[0071] When the second camera 5 is transferred from the top of the three-dimensional tape to the right side of the three-dimensional tape, during this process, the distance between the second camera 5 and the three-dimensional tape gradually increases. In this state, the telescopic assembly 18 drives the second camera 5 to extend towards the three-dimensional tape.

[0072] Furthermore, through the telescopic assembly 18, it can effectively ensure that the distance between the second camera 5 and the three-dimensional tape always remains appropriate, and there will be no situation where the distance between the second camera 5 and the three-dimensional tape is too far or too close. Therefore, it is beneficial to ensure the clarity of the shooting of the three-dimensional tape by the second camera 5.

[0073] Specifically, referring to Figure 2 、 Figure 3 and Figure 4 , the telescopic assembly 18 includes a telescopic toothed ring 181 and a first gear 182. The telescopic toothed ring 181 is located in the first adjustment groove 17, and the first gear 182 is meshingly installed inside the telescopic toothed ring 181. The top of the third driving rod 64 is connected to the side wall of the telescopic toothed ring 181. During the rotation of the first gear 182, it meshes with the telescopic toothed ring 181 and drives the telescopic toothed ring 181 to expand and contract. During the expansion and contraction of the telescopic toothed ring 181, it drives the third driving rod 64 to expand and contract, and further drives the second camera 5 to expand and contract through the third driving rod 64.

[0074] Specifically, referring to Figure 3 and Figure 4 , a movable hole 19 is formed through the side wall of the third driving rod 64, and the hinge rod between the second driving rod 63 and the third driving rod 64 is inserted into the movable hole 19. When the third driving rod 64 expands and contracts driven by the telescopic toothed ring 181, the movable hole 19 provides corresponding expansion and contraction space for the expansion and contraction of the third driving rod 64.

[0075] Specifically, the telescopic toothed ring 181 is integrally annular, and both its left and right inner sides are tooth-shaped. Half of the first gear 182 is tooth-shaped and the other half is smooth. The first gear 182 rotates counterclockwise inside the telescopic toothed ring 181.

[0076] When the second camera 5 is transferred from the left side of the three-dimensional tape to the top of the three-dimensional tape, during this process, the first gear 182 meshes with the teeth on the right side of the telescopic toothed ring 181. In this state, the telescopic toothed ring 181 is driven by the first gear 182 to contract upward, and further drives the third driving rod 64 and the second camera 5 to contract upward synchronously through the telescopic toothed ring 181;

[0077] When the second camera 5 is transferred from the top of the three-dimensional tape to the right side of the three-dimensional tape, during this process, the first gear 182 meshes with the teeth on the left side of the telescopic gear ring 181. In this state, the telescopic gear ring 181 extends downward under the drive of the first gear 182, and then drives the third drive rod 64 and the second camera 5 to extend downward synchronously through the telescopic gear ring 181.

[0078] Furthermore, through the telescopic assembly 18, it can effectively ensure that the distance between the second camera 5 and the three-dimensional tape always remains appropriate, and the situation where the distance between the second camera 5 and the three-dimensional tape is too far or too close will not occur. Therefore, it is beneficial to ensure the clarity of the shooting of the three-dimensional tape by the second camera 5.

[0079] Specifically, referring to Figure 3 、 Figure 4 and Figure 5 At the bottom of the first adjustment groove 17, a second adjustment groove 20 is penetrated along its opening direction. A second motor 21 is installed on the side of the adjustment plate 10 away from the telescopic gear ring 181. The second motor 21 is slidably arranged along the opening direction of the second adjustment groove 20. A first rotating shaft 22 is installed at the driving end of the second motor 21. One end of the first rotating shaft 22 away from the second motor 21 penetrates the second adjustment groove 20 and is connected to the axis of the first gear 182.

[0080] Referring to Figure 2 、 Figure 4 and Figure 5 The second motor 21 drives the first gear 182 to rotate within the telescopic gear ring 181 through the first rotating shaft 22, and then drives the second camera 5 to expand and contract through the telescopic gear ring 181.

[0081] When the driving cylinder 61 drives the telescopic gear ring 181 to rotate in the first adjustment groove 17 through the first drive rod 62, the second drive rod 63 and the third drive rod 64, the second motor 21 and the first rotating shaft 22 are synchronously driven by the first gear 182 to rotate in the second adjustment groove 20.

[0082] Furthermore, referring to Figure 2 、 Figure 3 and Figure 5 On the inner wall of the chassis 1, an installation box 23 is welded. An auxiliary component 24 is added in the installation box 23. The auxiliary component 24 is used to drive the adjustment plate 10 to rotate, so that when the second motor 21 rotates in the second adjustment groove 20, it is more stable and has higher efficiency.

[0083] Specifically, referring to Figure 2 、 Figure 4 and Figure 5, the auxiliary component 24 is located on the side of the adjusting plate 10 away from the sliding seat 9. The auxiliary component 24 includes a third motor 241, a second gear 242, a rack 243 and two auxiliary rods 244. The third motor 241 is fastened to the inside of the mounting box 23 by fastening bolts. The driving end of the third motor 241 faces downward, and a second rotating shaft 27 is vertically installed at the driving end of the third motor 241. The second gear 242 is connected to the second rotating shaft 27 in the horizontal direction. The rack 243 is horizontally arranged and meshed with the second gear 242. When the third motor 241 drives the second gear 242 to rotate, it simultaneously drives the rack 243 to slide horizontally.

[0084] Both the left and right ends of the rack 243 are wedge-shaped, and the bottoms of the two auxiliary rods 244 are also wedge-shaped. The bottoms of the two auxiliary rods 244 are respectively in wedge-shaped fit with the left and right ends of the rack 243. During the sliding process of the rack 243, it drives the two auxiliary rods 244 to move up and down.

[0085] Specifically, when the rack 243 slides to the right, the right auxiliary rod 244 is pushed up by the rack 243, and at the same time, the left auxiliary rod 244 moves down; when the rack 243 slides to the left, the left auxiliary rod 244 is pushed up by the rack 243, and at the same time, the right auxiliary rod 244 moves down.

[0086] Specifically, referring to Figure 5 and Figure 6 , a sliding groove 28 for the rack 243 to slide is opened at the bottom of the mounting box 23 along its length direction. The rack 243 is slidably installed in the sliding groove 28. When the third motor 241 drives the second gear 242 to rotate, it simultaneously drives the rack 243 to slide in the sliding groove 28 at the bottom of the mounting box 23.

[0087] At the same time, referring to Figure 2 , Figure 4 and Figure 5 , two movable blocks 25 are installed on the side of the adjusting plate 10 close to the third motor 241. Expansion rods 26 are installed between the two auxiliary rods 244 and the side wall of the adjusting plate 10. One end of the expansion rod 26 is connected to the corresponding auxiliary rod 244, and the other end of the expansion rod 26 extends into the corresponding movable block 25. When the two auxiliary rods 244 move up and down, the expansion rods 26 move up and down in the corresponding movable blocks 25. At the same time, since the bottom of the adjusting plate 10 is connected to the hinge seat 16 through the corresponding connecting rod, when the two expansion rods 26 move one up and one down, it drives the adjusting plate 10 to rotate. During the rotation of the adjusting plate 10, it provides certain assistance to the rotation of the third motor 241 and the telescopic gear ring 181, which is beneficial to improving the stability during the rotation of the third motor 241 and the telescopic gear ring 181.

[0088] Specifically, the side wall of the adjusting plate 10 is connected to the two telescopic rods 26. When the two telescopic rods 26 show the situation of "one rising and one falling", the part of the adjusting plate 10 connected to the two telescopic rods 26 will be in a state where one side is lifted upward and the other side is pulled downward. Since a hinge seat 16 is provided below the adjusting plate 10, when the adjusting plate 10 is in a state where one side is lifted upward and the other side is pulled downward, the adjusting plate 10 will rotate (similar to the principle of a seesaw). When the adjusting plate 10 rotates, during its rotation process, the second motor 21 will rotate in the corresponding direction under its own gravity. The second motor 21 itself can rotate driven by the driving cylinder 61. Now, the rotation of the adjusting plate 10 can also make the second motor 21 rotate in the corresponding direction under its own gravity. Therefore, it can be considered that there are two acting forces driving the second motor 21 to rotate simultaneously, which makes the rotation of the second motor 21 more stable.

[0089] In the embodiment of the present application, an infrared sensor for identifying a three-dimensional tape is installed at the front end of the conveyor belt. The sensor is installed on the conveyor belt through a vertical rod, and the sensor is located at the top of the vertical rod. When the three-dimensional tape passes by the sensor, the sensor recognizes that a tape has passed and transmits a signal to the second motor and the third motor. The second motor and the third motor start to rotate after receiving the signal.

[0090] Since the height of the flat tape is very low, when it passes by the sensor during its conveyance on the conveyor belt, the sensor cannot recognize the flat tape. In this state, the second motor and the third motor do not work.

[0091] The implementation principle of a tape vision detection device in the embodiment of the present application is as follows:

[0092] When the flat tape is conveyed into the chassis 1, only the first camera 4 operates. After the flat tape is conveyed into the interior of the chassis 1, in this state, the first camera 4 is fixed on the top of the chassis 1 and remains stationary. When the flat tape passes by below the first camera 4 during its conveyance, the top of the flat tape is defect-identified by the first camera 4.

[0093] When the three-dimensional tape is conveyed into the chassis 1, the first camera 4 and the second camera 5 operate simultaneously. Both the first camera 4 and the second camera 5 slide along with the three-dimensional tape. The first camera 4 identifies the top of the three-dimensional tape. During the forward sliding process, the second camera 5 can also swing left and right. That is, the second camera 5 can gradually move from the left side of the three-dimensional tape to the right side during the sliding process. Therefore, after the three-dimensional tape enters the chassis 1, the first camera 4 and the second camera 5 can perform a comprehensive defect identification and detection on the three-dimensional tape.

[0094] With this setting method, the first camera 4 and the second camera 5 can perform more comprehensive defect identification on the three-dimensional tape during the conveying process, which is beneficial to ensuring the daily processing and production of the three-dimensional tape and can further prevent the packaging of defective three-dimensional tapes.

[0095] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
