Description

Technical Field

[0001] The present application relates to the field of visual inspection equipment, and in particular to a material strip visual inspection equipment. Background Art

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

[0003] In the related technology, visual inspection equipment is also needed to conduct quality inspection on the material belt during daily processing and production. Specifically, after the material belt is processed, it will be transported to the next process for packaging through a conveyor belt. When the material belt is transported on the conveyor belt, the corresponding camera will identify the material belt to confirm whether there are quality defects in the material belt, thereby effectively preventing the defective material belt from being packaged.

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

[0005] The flat material strip is sheet-shaped and relatively thin. When the flat material strip is identified by a camera, only one camera needs to be placed directly above the flat material strip. The camera can be used to identify whether there are defects on the top of the flat material strip. There is no need to identify defects on the left and right sides of the flat material strip.

[0006] The three-dimensional material belt is annular in shape and small in size. It is transported independently one by one during the transportation process. After one three-dimensional material belt is transported, the next three-dimensional material belt is transported. Specifically, during the transportation process, it is necessary not only to identify defects on the top of the three-dimensional material belt, but also on the left and right sides of the three-dimensional material belt. The conventional practice is to use two cameras to identify the three-dimensional material belt. One camera is used to identify the top of the three-dimensional material belt, and the other camera is used to identify the side of the three-dimensional material belt.

[0007] However, the camera that identifies the side of the three-dimensional material belt is usually fixed on the chassis through a corresponding mounting frame, which makes the shooting angle of the camera fixed, resulting in the problem of a single shooting angle. At the same time, in order to ensure the molding quality of the three-dimensional material belt, the three-dimensional material belt needs to be identified on both sides during the conveying process. This requires the camera to be transferred from one side of the three-dimensional material belt to the other side when identifying the three-dimensional material belt. However, most cameras are fixed in the chassis, which means that the camera can only identify one side of the three-dimensional material belt and cannot be transferred to the other side of the three-dimensional material belt for identification. As a result, there is a problem of insufficient comprehensive identification of the three-dimensional material belt, which is not conducive to the daily processing and production of the three-dimensional material belt. Summary of the invention

[0008] The present application provides a material strip visual inspection device, the purpose of which is to perform more comprehensive defect identification on the three-dimensional material strip during the conveying process, which is beneficial to ensure the daily processing and production of the three-dimensional material strip, and can further avoid the packaging of defective three-dimensional material strips.

[0009] The present application provides a material strip visual inspection device, which adopts the following technical solution: A material belt visual inspection device comprises a chassis, wherein a conveyor belt is installed horizontally inside the chassis, and both left and right ends of the conveyor belt extend outward from the chassis, and both left and right sides of the conveyor belt are installed with limit plates in the vertical direction, and a first camera and a second camera are provided in the chassis, the first camera and the second camera are arranged at an interval, and the first camera and the second camera are both slidably arranged on the top of the chassis, and an adjustment component is added in the chassis, and the adjustment component is used to drive the second camera to rotate during the sliding process.

[0010] By adopting the above technical solution, when the flat material strip is conveyed into the chassis, only the first camera is operated. After the flat material strip is conveyed into the chassis, in this state, the first camera is fixed on the top of the chassis and remains stationary. When the flat material strip passes under the first camera during the conveying process, the first camera is used to identify defects on the top of the flat material strip.

[0011] When the three-dimensional material belt is transported into the chassis, the first camera and the second camera operate at the same time. Both the first camera and the second camera slide along with the three-dimensional material belt. The first camera identifies the top of the three-dimensional material belt, and the second camera can also swing left and right during the forward sliding process. That is, the second camera can gradually move from the left side of the three-dimensional material belt to the right side of the three-dimensional material belt during the sliding process. After the three-dimensional material belt enters the chassis, the first camera and the second camera can perform comprehensive defect recognition and detection on the three-dimensional material belt.

[0012] This arrangement enables more comprehensive defect identification of the three-dimensional material strip during transportation through the first camera and the second camera, which is beneficial to ensure the daily processing and production of the three-dimensional material strip and can further avoid the packaging of defective three-dimensional material strips.

[0016] By adopting the above technical solution, when the conveyor belt is conveying a three-dimensional material belt, the first motor is used to drive the sliding seat to slide toward the direction close to the connecting plate until the two connecting rods are respectively inserted into the two connecting holes, and the sliding seat and the connecting plate are connected by the two connecting rods and the two connecting 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, and the sliding seat synchronously drives the connecting plate, the adjustment plate and the second camera to slide during the forward movement. The second camera gradually moves from the left side of the three-dimensional material belt to the right side of the three-dimensional material belt during the forward movement, and then the first camera and the second camera are used to complete the comprehensive recognition of the three-dimensional material belt.

[0018] By adopting the above technical solution, when the second camera is specifically rotating, the driving cylinder drives the moving seat to slide in the installation groove. During the sliding process, the moving seat is hinged with the first driving rod, and then the first driving rod is driven to rotate through the moving seat. When the first driving rod rotates, the second driving rod is synchronously driven to rotate. When the second driving rod rotates, the third driving rod drives the second camera to rotate, so that the second camera can be transferred from the left side of the three-dimensional material strip to the right side of the three-dimensional material strip.

[0019] Preferably, a first arc-shaped adjustment groove is opened on one side of the adjustment plate close to the sliding seat, and the first adjustment groove is located above the mounting groove.

The telescopic component can be telescoped while sliding in the first adjusting groove.

[0021] The second camera is transferred from the left side to the right side of the stereo material strip: When the second camera moves from the left side of the three-dimensional material belt to the top of the three-dimensional material belt, since the rotation trajectory of the second camera is an arc, the distance between the second camera and the three-dimensional material belt is gradually reduced during this process. In this state, the telescopic component drives the second camera to shrink in the direction away from the three-dimensional material belt; When the second camera is transferred from the top of the three-dimensional material strip to the right side of the three-dimensional material strip, the distance between the second camera and the three-dimensional material strip gradually increases during this process.

[0024] By adopting the above technical solution, when the third driving rod is extended and retracted under the drive of the telescopic gear ring, the movable hole provides a corresponding telescopic space for the extension and retraction of the third driving rod. The first gear meshes with the telescopic gear ring during the rotation process and drives the telescopic gear ring to extend and retract. During the extension and retraction process, the telescopic gear ring drives the third driving rod to extend and retract, and then drives the second camera to extend and retract through the third driving rod.

[0025] When the second camera is transferred from the left side of the three-dimensional material belt to the top of the three-dimensional material belt, during this process, the first gear is meshed with the teeth on the right side of the telescopic gear ring. In this state, the telescopic gear ring is contracted under the drive of the first gear, and then the third driving rod and the second camera are driven to contract synchronously through the telescopic gear ring; When the second camera is transferred from the top of the three-dimensional material belt to the right side of the three-dimensional material belt, during this process, the first gear is engaged with the teeth on the left side of the telescopic gear ring. In this state, the telescopic gear ring is extended under the drive of the first gear, and then the third driving rod and the second camera are driven to extend synchronously through the telescopic gear ring.

[0026] Furthermore, the telescopic component can effectively ensure that the distance between the second camera and the three-dimensional material strip is always kept appropriate, and the distance between the second camera and the three-dimensional material strip will not be too far or too close, which is beneficial to ensure the clarity of the second camera's shooting of the three-dimensional material strip.

[0028] 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 second motor and the first rotating shaft are synchronously driven to rotate in the second adjustment groove through the first gear.

[0029] Preferably, a mounting box is fixed on the inner wall of the chassis, and an auxiliary component is added in the mounting box, and the auxiliary component is used to drive the adjustment plate to rotate; The auxiliary assembly includes a third motor, a second gear, a rack and two auxiliary rods; the third motor is fastened to the installation box, the second shaft is vertically installed at the driving end of the third motor, the second gear is connected to the second shaft in the horizontal direction, the rack is horizontally arranged, the rack is meshed with the second gear, the third motor drives the second gear to rotate, and the second gear drives the rack to slide in the horizontal direction; The left and right ends of the rack are both wedge-shaped, and the bottoms of the two auxiliary rods are both wedge-shaped.

When the flat material strip passes under the first camera during the conveying process, the first camera is used to identify defects on the top of the flat material strip.

[0032] When the three-dimensional material belt is transported into the chassis, the first camera and the second camera operate at the same time. Both the first camera and the second camera slide along with the three-dimensional material belt. The first camera identifies the top of the three-dimensional material belt, and the second camera can also swing left and right during the forward sliding process.

[0036] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.

[0037] Example: The present application embodiment discloses a material strip visual inspection device, referring to Figure 1 and Figure 2 , including a chassis 1, which is in the shape of a rectangular parallelepiped and hollow inside. A conveyor belt 2 is installed in the horizontal direction inside the chassis 1, and the left and right ends of the conveyor belt 2 extend outward from the chassis 1, and limit plates 3 are installed in the vertical direction on 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 in the chassis 1, and the first camera 4 and the second camera 5 are both slidably set 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, and along the conveying direction of the conveyor belt 2, the first camera 4 is in front and the second camera 5 is in the back. The distance between the first camera 4 and the second camera 5 can be adjusted according to the specific size of the material belt, thereby ensuring that the first camera 4 and the second camera 5 can both clearly take pictures and identify the material belt.

[0038] When inspecting the material belt, the material belt is transported to the inside of the chassis 1 through the conveyor belt 2 for defect identification. During the conveying of the material belt on the conveyor belt 2, the limiting plates 3 on both sides of the conveyor belt 2 limit the material belt, and the limiting plates 3 prevent the material belt from falling from the conveyor belt 2. The distance between the two limiting plates 3 and the width of the conveyor belt 2 can be adjusted to accommodate material belts of different sizes.

[0039] When the flat material strip is conveyed into the chassis 1, only the first camera 4 operates. After the flat material strip is conveyed into 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 material 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 material strip.

[0040] When the three-dimensional material belt is conveyed into the chassis 1, the first camera 4 and the second camera 5 operate simultaneously. The first camera 4 and the second camera 5 both slide along with the three-dimensional material belt, and the first camera 4 identifies the top of the three-dimensional material belt. The second camera 5 can also swing left and right during the forward sliding process, that is, the second camera 5 can gradually move from the left side of the three-dimensional material belt to the right side of the three-dimensional material belt during the sliding process. Then, after the three-dimensional material belt enters the chassis 1, the first camera 4 and the second camera 5 can perform comprehensive defect recognition and detection on the three-dimensional material belt.

[0041] This arrangement enables more comprehensive defect identification of the three-dimensional material strip during transportation through the first camera 4 and the second camera 5, which is beneficial to ensure the daily processing and production of the three-dimensional material strip and can further avoid packaging of defective three-dimensional material strips.

[0042] The second camera 5 is initially located at one side of the three-dimensional material belt, that is, the left side or the right side. In this embodiment, the second camera 5 is initially located at the left side of the three-dimensional material belt. When the three-dimensional material belt enters the chassis 1, the second camera 5 starts to slide along with the three-dimensional material belt, and at the same time identifies one side of the three-dimensional material belt, and gradually rotates toward the other side of the three-dimensional material belt. When the three-dimensional material belt is transported to the exit of the chassis 1, the second camera 5 moves to the other side of the three-dimensional material belt to complete the identification of the other side of the three-dimensional material belt.

[0043] Specifically, refer to Figure 1 and Figure 2 The side wall of the chassis 1 is fastened with a first motor 7 by fastening bolts, a screw 8 is installed at the driving end of the first motor 7 in the horizontal direction, and the top of the first camera 4 is connected to a sliding seat 9 through a corresponding connecting rod. The screw 8 penetrates the sliding seat 9 and is threadedly matched with the sliding seat 9. When the three-dimensional material belt enters the chassis 1, the first motor 7 is turned on. While the first motor 7 drives the screw 8 to rotate, it simultaneously drives the sliding seat 9 and the first camera 4 to slide along the length direction of the screw 8. The first motor 7 is a forward and reverse motor. When the material belt has finished running in the chassis 1, the first camera 4 is driven to reset by the first motor 7.

[0044] At the same time, refer to Figure 1 and Figure 2, an arc-shaped adjustment plate 10 is provided inside the chassis 1, and the second camera 5 is installed on the adjustment plate 10. The adjustment plate 10 is arranged vertically, and the top of the adjustment plate 10 is connected to an independent connecting plate 11 through a spring, and circular connecting holes 12 are provided on the left and right ends of the connecting plate 11 close to the sliding seat 9, and connecting rods 13 are welded horizontally on the left and right ends of the sliding seat 9 close to the connecting plate 11, and the two connecting rods 13 correspond to the two connecting holes 12 one by one. When the conveyor belt 2 conveys a three-dimensional material belt, the sliding seat 9 is first driven by the first motor 7 to slide in the direction close to 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 sliding seat 9 is driven forward by the first motor 7, and the sliding seat 9 drives the connecting plate 11, the adjustment plate 10 and the second camera 5 to slide synchronously during the forward movement. The second camera 5 gradually moves from the left side of the three-dimensional material strip to the right side of the three-dimensional material strip during the forward movement, thereby completing the comprehensive recognition of the three-dimensional material strip through the first camera 4 and the second camera 5 .

[0045] The inner wall of the connection hole 12 is embedded with a rubber pad, which is elastic. After the connection rod 13 is inserted into the connection hole 12, the rubber pad can clamp the connection rod 13. At the same time, the rubber pad can increase the friction between the connection rod 13, which is conducive to ensuring the stability of the connection between the sliding seat 9 and the connecting plate 11. When the sliding seat 9 and the connecting plate 11 need to be separated, the connecting plate 11 is manually limited, and the sliding seat 9 slides forward to make the connecting rod 13 slide out of the corresponding connection hole 12.

[0046] In the actual production process, when the material strip is visually identified, it is often reported in advance. If today is the identification of a flat material strip, the workshop staff can separate the sliding seat 9 and the connecting plate 11 in advance, and after the flat material strip enters the chassis 1, only the first camera 4 can operate. If today is the identification of a three-dimensional material strip, the workshop staff can connect the sliding seat 9 and the connecting plate 11 in advance, and use the first camera 4 and the second camera 5 to perform comprehensive defect identification on the three-dimensional material strip at the same time. Therefore, the installation and disassembly between the sliding seat 9 and the connecting plate 11 does not need to be performed frequently.

[0047] Reference Figure 2 and Figure 3 An adjustment component 6 is provided on the adjustment plate 10, and the adjustment component 6 is used to adjust the second camera 5 from the left side of the three-dimensional material belt to the right side of the three-dimensional material belt.

[0048] Specifically, refer to Figure 2 and Figure 3The adjustment assembly 6 includes a driving cylinder 61, a first driving rod 62, a second driving rod 63 and a third driving rod 64. A strip-shaped mounting groove 14 is provided in the horizontal direction on one side of the adjustment plate 10 close to the sliding seat 9, and the driving cylinder 61 is fastened to the mounting groove 14 by corresponding fastening bolts. A moving seat 15 is integrally connected to the piston rod of the driving cylinder 61, and a hinge rod is welded on the moving seat 15. One end of the first driving rod 62 is hingedly connected to the moving seat 15 through the hinge rod, and the other end of the first driving rod 62 away from the moving seat 15 is hingedly connected to the side wall of the second driving rod 63 through the corresponding hinge rod. The bottom of the adjustment plate 10 is integrally connected to the hinge seat 16 through the corresponding connecting rod, the bottom of the second driving rod 63 is hingedly connected to the hinge seat 16 through the hinge rod, and the top of the second driving rod 63 is connected to the third driving rod 64 through the corresponding connecting rod. The bottom of the third driving rod 64 is integrally connected to the second camera 5.

[0049] When the second camera 5 is rotating, the driving cylinder 61 drives the moving seat 15 to slide in the installation groove 14. The moving seat 15 is hinged with the first driving rod 62 during the sliding process, and then the first driving rod 62 is driven to rotate through the moving seat 15. When the first driving rod 62 rotates, it simultaneously drives the second driving rod 63 to rotate. When the second driving rod 63 rotates, 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 strip to the right side of the three-dimensional material strip.

[0050] Further, refer to Figure 2 , Figure 3 as well as Figure 4 The adjustment plate 10 is provided with an arc-shaped first adjustment groove 17 on one side close to the sliding seat 9, and the first adjustment groove 17 is located above the mounting groove 14. A telescopic assembly 18 is added in the first adjustment groove 17, and the telescopic assembly 18 is slidably arranged in the first adjustment 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 telescope 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, the telescopic assembly 18 is synchronously driven to rotate in the first adjustment groove 17, and the telescopic assembly 18 can be telescoped while sliding in the first adjustment groove 17.

[0051] During the process of the second camera 5 being transferred from the left side to the right side of the three-dimensional material strip: When the second camera 5 is transferred from the left side of the three-dimensional material belt to the top of the three-dimensional material belt, since the rotation trajectory of the second camera 5 is an arc, the distance between the second camera 5 and the three-dimensional material belt is gradually reduced during this process. In this state, the telescopic component 18 drives the second camera 5 to retract in the direction away from the three-dimensional material belt; When the second camera 5 is transferred from the top of the three-dimensional material strip to the right side of the three-dimensional material strip, the distance between the second camera 5 and the three-dimensional material strip gradually increases during this process. In this state, the telescopic component 18 drives the second camera 5 to extend toward the direction close to the three-dimensional material strip.

[0052] Furthermore, the telescopic component 18 can effectively ensure that the distance between the second camera 5 and the three-dimensional material strip is always kept appropriate, and the distance between the second camera 5 and the three-dimensional material strip will not be too far or too close, which is beneficial to ensuring the clarity of the three-dimensional material strip captured by the second camera 5.

[0053] Specifically, refer to Figure 2 , Figure 3 as well as Figure 4 The telescopic assembly 18 includes a telescopic gear ring 181 and a first gear 182. The telescopic gear ring 181 is located in the first adjustment slot 17, and the first gear 182 is meshed and installed inside the telescopic gear ring 181. The top of the third driving rod 64 is connected to the side wall of the telescopic gear ring 181. The first gear 182 meshes with the telescopic gear ring 181 during the rotation process and drives the telescopic gear ring 181 to telescope. During the telescopic process, the telescopic gear ring 181 drives the third driving rod 64 to telescope, and then drives the second camera 5 to telescope through the third driving rod 64.

[0054] Specifically, refer to Figure 3 and Figure 4 The side wall of the third driving rod 64 is penetrated with an active hole 19, and the hinge rod between the second driving rod 63 and the third driving rod 64 is inserted into the active hole 19. When the third driving rod 64 is extended and retracted under the drive of the telescopic gear ring 181, the active hole 19 provides a corresponding telescopic space for the extension and retraction of the third driving rod 64.

[0055] Specifically, the telescopic gear ring 181 is annular in shape, and its left and right inner sides are both tooth-shaped. One half of the first gear 182 is tooth-shaped, and the other half is smooth. The first gear 182 rotates counterclockwise in the telescopic gear ring 181.

[0056] When the second camera 5 is transferred from the left side of the three-dimensional material belt to the top of the three-dimensional material belt, during this process, the first gear 182 is meshed with the teeth on the right side of the telescopic gear ring 181. In this state, the telescopic gear ring 181 is driven by the first gear 182 to retract upward, and then the telescopic gear ring 181 drives the third driving rod 64 and the second camera 5 to retract upward synchronously; When the second camera 5 is transferred from the top of the three-dimensional material belt to the right side of the three-dimensional material belt, during this process, the first gear 182 engages with the teeth on the left side of the telescopic gear ring 181. In this state, the telescopic gear ring 181 is extended downward under the drive of the first gear 182, and then the third driving rod 64 and the second camera 5 are driven by the telescopic gear ring 181 to extend downward synchronously.

[0057] Furthermore, the telescopic component 18 can effectively ensure that the distance between the second camera 5 and the three-dimensional material strip is always kept appropriate, and the distance between the second camera 5 and the three-dimensional material strip will not be too far or too close, which is beneficial to ensuring the clarity of the three-dimensional material strip captured by the second camera 5.

[0058] Specifically, refer to Figure 3 , Figure 4 as well as Figure 5 A second adjusting groove 20 is provided at the bottom of the first adjusting groove 17 along its opening direction, a second motor 21 is installed on the side of the adjusting plate 10 away from the telescopic gear ring 181, the second motor 21 is slidably arranged along the opening direction of the second adjusting groove 20, a first rotating shaft 22 is installed at the driving end of the second motor 21, and an end of the first rotating shaft 22 away from the second motor 21 passes through the second adjusting groove 20 and is connected to the axis of the first gear 182.

[0059] Reference Figure 2 , Figure 4 as well as Figure 5 The second motor 21 drives the first gear 182 to rotate in the telescopic gear ring 181 through the first rotating shaft 22, and then drives the second camera 5 to be telescopic through the telescopic gear ring 181.

[0060] When the driving cylinder 61 drives the telescopic gear ring 181 to rotate in the first adjustment groove 17 through the first driving rod 62, the second driving rod 63 and the third driving rod 64, the second motor 21 and the first rotating shaft 22 are synchronously driven to rotate in the second adjustment groove 20 through the first gear 182.

[0061] Further, refer to Figure 2 , Figure 3 as well as Figure 5 A mounting box 23 is welded on the inner wall of the chassis 1, and an auxiliary component 24 is added in the mounting box 23. The auxiliary component 24 is used to drive the adjustment plate 10 to rotate, so that the second motor 21 rotates in the second adjustment slot 20 more stably and efficiently.

[0062] Specifically, refer to Figure 2 , Figure 4 as well as Figure 5The auxiliary component 24 is located on the side of the adjustment plate 10 away from the sliding seat 9, and 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 installation 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, and the second gear 242 is connected to the second rotating shaft 27 in the horizontal direction. The rack 243 is arranged horizontally, and the rack 243 is meshed and connected with the second gear 242. While the third motor 241 drives the second gear 242 to rotate, it also drives the rack 243 to slide in the horizontal direction.

[0063] The left and right ends of the rack 243 are both wedge-shaped, and the bottoms of the two auxiliary rods 244 are both wedge-shaped. The bottoms of the two auxiliary rods 244 are respectively wedge-matched with the left and right ends of the rack 243. The rack 243 drives the two auxiliary rods 244 to rise and fall during the sliding process.

[0064] Specifically, when the rack 243 slides to the right, the auxiliary rod 244 on the right is pushed up by the rack 243, and the auxiliary rod 244 on the left is downward; when the rack 243 slides to the left, the auxiliary rod 244 on the left is pushed up by the rack 243, and the auxiliary rod 244 on the right is downward.

[0065] Specifically, refer to Figure 5 and Figure 6 The bottom of the installation box 23 is provided with a slide groove 28 along its length direction for the rack 243 to slide, and the rack 243 is slidably installed in the slide groove 28. While the third motor 241 drives the second gear 242 to rotate, it also drives the rack 243 to slide in the slide groove 28 at the bottom of the installation box 23.

[0066] At the same time, refer to Figure 2 , Figure 4 as well as Figure 5 Two movable blocks 25 are installed on the side of the adjustment plate 10 close to the third motor 241, and telescopic rods 26 are installed between the two auxiliary rods 244 and the side wall of the adjustment plate 10. One end of the telescopic rod 26 is connected to the corresponding auxiliary rod 244, and the other end of the telescopic rod 26 extends into the corresponding movable block 25. When the two auxiliary rods 244 are lifted and lowered, the telescopic rods 26 are lifted and lowered in the corresponding movable block 25. At the same time, since the bottom of the adjustment plate 10 is connected to the hinge seat 16 through the corresponding connecting rod, the two telescopic rods 26 drive the adjustment plate 10 to rotate during the process of lifting and lowering. During the rotation process, the adjustment plate 10 assists the rotation of the third motor 241 and the telescopic gear ring 181 to a certain extent, which is conducive to improving the stability of the third motor 241 and the telescopic gear ring 181 during the rotation process.

[0067] Specifically, the side wall of the adjustment plate 10 is connected to the two telescopic rods 26. When the two telescopic rods 26 are "one up and one down", the part of the adjustment plate 10 connected to the two telescopic rods 26 will be in a state where one side is lifted up and the other side is pulled down. Since a hinge seat 16 is provided below the adjustment plate 10, when the adjustment plate 10 is in a state where one side is lifted up and the other side is pulled down, the adjustment plate 10 will rotate (similar to the principle of a seesaw). When the adjustment plate 10 rotates, during its rotation, the second motor 21 will rotate in the corresponding direction under the action of its own gravity. The second motor 21 itself can rotate under the drive of the driving cylinder 61. Now the rotation of the adjustment plate 10 can make the second motor 21 rotate in the corresponding direction under the action of its own gravity. It can be considered that there are two forces driving the second motor 21 to rotate at the same time, which makes the rotation of the second motor 21 more stable.

[0068] In the embodiment of the present application, an infrared sensor for identifying the three-dimensional material belt is installed at the front end of the conveyor belt, and 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 material belt passes through the sensor, the sensor recognizes that the material belt has passed, and transmits a signal to the second motor and the third motor, and the second motor and the third motor start to rotate after receiving the signal.

[0069] Since the height of the flat material belt is very low, the sensor cannot identify the flat material belt when it passes the sensor on the conveyor belt. In this state, the second motor and the third motor will not work.

[0070] The implementation principle of a material strip visual inspection device in the embodiment of the present application is: When the flat material strip is conveyed into the chassis 1, only the first camera 4 operates. After the flat material strip is conveyed into 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 material 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 material strip.

[0071] When the three-dimensional material belt is conveyed into the chassis 1, the first camera 4 and the second camera 5 operate simultaneously. The first camera 4 and the second camera 5 both slide along with the three-dimensional material belt, and the first camera 4 identifies the top of the three-dimensional material belt. The second camera 5 can also swing left and right during the forward sliding process, that is, the second camera 5 can gradually move from the left side of the three-dimensional material belt to the right side of the three-dimensional material belt during the sliding process. Then, after the three-dimensional material belt enters the chassis 1, the first camera 4 and the second camera 5 can perform comprehensive defect recognition and detection on the three-dimensional material belt.

[0072] This arrangement enables more comprehensive defect identification of the three-dimensional material strip during transportation through the first camera 4 and the second camera 5, which is beneficial to ensure the daily processing and production of the three-dimensional material strip and can further avoid packaging of defective three-dimensional material strips.

[0073] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
