Description

Technical Field

[0001] This utility model relates to the field of roll material slitting technology, specifically to an identification device developed for the appearance AOI of roll material slitting. Background Technology

[0002] Traditional slitting machines rely on manual visual inspection of the strips for appearance and quality assessment during operation. However, once the machine starts running at high speed, due to the excessive speed and distance limitations, it becomes difficult for manual visual inspection to accurately observe and judge the condition of the strips. To solve this problem and ensure that workers can observe the condition of the strips being processed in real time and clearly, identification devices are installed on the slitting machine. These devices use technology to assist workers in making accurate identifications, thereby improving production efficiency and product quality.

[0003] In existing technologies, during actual production, the slitting production environment is usually quite complex, with a large amount of dust, oil, and metal shavings present in the workshop. These impurities are easily dispersed and adhere to the camera screen under the airflow and vibration generated by the equipment operation. When impurities adhere to the camera screen surface, it will seriously affect the operator's observation of the screen image, making it impossible for the operator to accurately judge the actual state of the strip, and may even lead to misjudgment of normal features in the image, thus causing unnecessary production interference. In order to ensure the accuracy of monitoring and the stability of production, once impurities are found to be attached to the camera screen, the operator has to stop the operation of the slitting equipment and then carefully clean the camera screen. This shutdown and cleaning process not only interrupts the continuity of production, reduces production efficiency, but also increases production costs. Utility Model Content

[0007] In a preferred embodiment of this technical solution, the mounting plate has a limiting groove at the relative position of the first threaded rod, and the first threaded rod is rotatably connected to the groove.

[0010] In a preferred embodiment of this technical solution, the snap-fit ​​assembly includes a connecting sleeve fixedly connected to a first gear, a second threaded rod rotatably connected to the connecting sleeve, a first knob fixedly connected to one end of the second threaded rod, a connecting plate threadedly connected to the second threaded rod, a connecting rod fixedly connected to the connecting plate, a fixing rod fixedly connected to the connecting rod, a second sliding block slidably connected to the connecting sleeve, a first spring fixedly connected between the second sliding block and the connecting sleeve, and a snap-fit ​​block fixedly connected to the second sliding block. The fixing rod is slidably connected to the second sliding block, the connecting rod is slidably connected to the main body of the device, and the snap-fit ​​block is snap-fitted to the connecting shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By having staff activate the relevant components, the cleaning roller rotates, and air is sprayed from the air nozzle to clean the surface of the high-speed camera module mirror. This forms a dual cleaning mechanism of "mechanical wiping + airflow blowing". This synergistic cleaning method can not only fully remove impurities from the mirror surface, but also avoid the problem of impurity residue that may be caused by a single cleaning method, ensuring the cleanliness of the camera surface of the high-speed camera module.

[0015] 2. When the drive component moves the sliding bracket, the meshing transmission between the first gear and the fixed rack will synchronously drive the snap-fit ​​component and the cleaning roller body to rotate.

[0016] 3. When it is necessary to replace the connecting shaft and the cleaning roller body, the operator only needs to turn the first knob to drive the second threaded rod to rotate, which will cause the locking block to disengage from the connecting shaft and release the limit state. The whole process does not require complicated tools, the operation steps are simple and intuitive, which greatly shortens the replacement time and reduces the difficulty of operation for the operator. It is especially suitable for rapid maintenance scenarios on the production line. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 7This utility model provides an embodiment of an identification device for AOI (Automated Optical Inspection) development of roll material slitting, comprising a device body 1, a conveying assembly disposed on the device body 1, a first fixed bracket 21 fixedly mounted on the device body 1, an adjusting assembly disposed on the first fixed bracket 21, a mounting plate 22 mounted on the adjusting assembly, a high-speed camera module 23 fixedly mounted on the mounting plate 22, a driving assembly disposed on the mounting plate 22, a sliding bracket 24 disposed on the driving assembly, a first gear 25 rotatably connected to the sliding bracket 24, a fixed rack 26 fixedly mounted on the mounting plate 22, a snap-fit ​​assembly disposed on the first gear 25, a connecting shaft 27 mounted on the snap-fit ​​assembly, a cleaning roller body 28 fixedly connected to the connecting shaft 27, an air pump body 29 fixedly mounted on the mounting plate 22, and an air outlet nozzle 210 fixedly mounted on the sliding bracket 24. A connecting hose 211 is fixedly connected between the air nozzle 210 and the air pump body 29. A first gear 25 meshes with a fixed rack 26. An adjustment component is used to adjust the height of the mounting plate 22. The cleaning roller body 28, in cooperation with the air nozzle 210, cleans the dust on the camera surface of the high-speed camera module 23. A drive component drives the sliding bracket 24 to move. When the sliding bracket 24 moves, the first gear 25 meshes with the fixed rack 26, causing the clamping component to rotate. When the clamping component rotates, it causes the connecting shaft 27 and the cleaning roller body 28 to rotate. This embodiment needs to be used in conjunction with an external sorting machine. After the external sorting machine cuts the strips, they are conveyed to the main body 1 of the device through its own conveying device. Before the equipment starts, the position of the mounting plate 22 is adjusted by the adjustment component. The strips are conveyed forward by the conveying component. When the strips pass the first fixed bracket 21, they are conveyed by the high-speed... The camera module 23 captures photos and displays them on an external connection for staff observation. When the mirror surface of the high-speed camera module 23 needs to be cleaned, the drive component starts working, causing the sliding bracket 24 to slide back and forth. When the sliding bracket 24 moves, the first gear 25 cooperates with the fixed rack 26, causing the locking component, the connecting shaft 27, and the cleaning roller body 28 to rotate, cleaning the mirror surface of the high-speed camera module 23. Air is drawn from the outside by the air pump body 29 and delivered to the air nozzle 210 through the connecting hose 211 to blow away the surface of the high-speed camera module 23, thus replacing manual cleaning of the mirror surface of the high-speed camera module 23. When the connecting shaft 27 and the cleaning roller body 28 need to be replaced, the locking component is adjusted to release the restriction on the connecting shaft 27, and then the connecting shaft 27 and the cleaning roller body 28 are removed for replacement.

[0027] Please see Figure 1 - Figure 3A further embodiment of this solution is as follows: the adjustment assembly includes a first threaded rod 212 threadedly connected to the first fixed bracket 21, a rotating disk 213 fixedly connected to the first threaded rod 212, and a first guide rod 214 fixedly mounted on the mounting plate 22. The first threaded rod 212 is rotatably connected to the mounting plate 22, and the first guide rod 214 is slidably connected to the first fixed bracket 21. The rotating disk 213 is used to adjust the rotation of the first threaded rod 212. The rotation of the first threaded rod 212 drives the mounting plate 22 to move. By rotating the rotating disk 213, the rotation of the first threaded rod 212 can be controlled, thereby meeting the position adjustment requirements under different working conditions. The sliding cooperation between the first guide rod 214 and the first fixed bracket 21 provides stable guidance for the movement of the mounting plate 22, preventing the mounting plate 22 from shifting or tilting during movement, ensuring that the mounting plate 22 drives the related components to move smoothly, and improving the accuracy and stability of the adjustment process.

[0028] Please see Figure 1 - Figure 3 A further solution based on this embodiment is as follows: the mounting plate 22 has a limiting groove at the relative position of the first threaded rod 212, the first threaded rod 212 is rotatably connected to the groove, and the limiting groove on the mounting plate 22 provides a limit for the first threaded rod 212, so that the first threaded rod 212 will not disengage from the mounting plate 22 when it rotates, thereby driving the mounting plate 22 to move.

[0029] Please see Figure 1 - Figure 4 A further embodiment of this solution is as follows: the drive assembly includes a first motor 215 fixedly mounted on the mounting plate 22, a reciprocating lead screw 216 fixedly connected to the output end of the first motor 215, a second guide rod 217 fixedly connected to the mounting plate 22, a first sliding block 218 slidably connected to the second guide rod 217, and a rotating block 219 rotatably connected to the first sliding block 218. A sliding bracket 24 is fixedly mounted on the first sliding block 218. The reciprocating lead screw 216 is rotatably connected to the mounting plate 22, and the rotating block 219 is slidably connected to the reciprocating lead screw 216. The first motor 215... 5 is used to drive the reciprocating lead screw 216 to rotate. Through the cooperation of the reciprocating lead screw 216 and the rotating block 219, the first sliding block 218 is driven to move. The first motor 215 drives the reciprocating lead screw 216 to rotate. Through the cooperation of the rotating block 219 and the reciprocating lead screw 216, the rotational motion is converted into the reciprocating linear motion of the first sliding block 218, so as to realize the reciprocating movement of the sliding bracket 24. The second guide rod 217 strictly limits the movement trajectory of the first sliding block 218 to prevent the sliding block from deviating during the movement, ensuring the movement accuracy of the sliding bracket 24 and improving the working efficiency and stability of the drive assembly.

[0030] Please see Figure 1 - Figure 4 A further solution based on this embodiment is as follows: the first sliding block 218 has a matching groove at the relative position of the second guide rod 217. The first sliding block 218 is slidably connected to the second guide rod 217 through the groove. The matching groove design makes the first sliding block 218 and the second guide rod 217 fit tightly together, reducing the offset and shaking during the sliding process, and ensuring that the first sliding block 218 can move smoothly with the rotation of the reciprocating screw 216.

[0031] Please see Figure 1 - Figure 6 A further solution based on this embodiment is as follows: the snap-fit ​​assembly includes a connecting sleeve 31 fixedly connected to the first gear 25, a second threaded rod 32 rotatably connected to the connecting sleeve 31, a first knob 33 fixedly connected to one end of the second threaded rod 32, a connecting plate 34 threadedly connected to the second threaded rod 32, a connecting rod 35 fixedly connected to the connecting plate 34, a fixing rod 36 fixedly connected to the connecting rod 35, a second sliding block 37 slidably connected to the connecting sleeve 31, a first spring 38 fixedly connected between the second sliding block 37 and the connecting sleeve 31, and a snap-fit ​​block 39 fixedly connected to the second sliding block 37. The fixing rod 36 is slidably connected to the second sliding block 37, the connecting rod 35 is slidably connected to the device body 1, and the snap-fit ​​block 39 is snap-fitted to the connecting shaft 27. 7 is installed on the connecting bushing 31. The first knob 33 is used to adjust the rotation of the second threaded rod 32. The rotation of the second threaded rod 32 adjusts the movement of the connecting rod 35 and the fixed rod 36. The movement of the fixed rod 36 and the second sliding block 37 drives the locking block 39 to move. The rotation of the first knob 33 drives the second threaded rod 32 to rotate. The threaded transmission belt 313 moves the connecting plate 34, the connecting rod 35 and the fixed rod 36. The fixed rod 36 pushes the second sliding block 37 to compress the first spring 38, so that the locking block 39 disengages from the connecting shaft 27, realizing quick disassembly. After the adjustment is released, the elastic force of the first spring 38 pushes the second sliding block 37 to reset, and drives the locking block 39 to re-lock the connecting shaft 27, ensuring a stable connection between the connecting bushing 31 and the connecting shaft 27, thereby facilitating the installation, replacement and maintenance of the components.

[0032] Please see Figure 1 - Figure 6 A further solution based on this embodiment is as follows: the second sliding block 37 has a limiting groove at the relative position of the fixed rod 36, the fixed rod 36 is slidably connected to the groove, and the limiting groove provides precise guidance for the movement of the fixed rod 36, ensuring that the fixed rod 36 can push the second sliding block 37 along the preset trajectory, avoiding misalignment between the fixed rod 36 and the second sliding block 37, and ensuring the smoothness and stability of the adjustment process of the snap-fit ​​component.

[0033] Please see Figure 1 - Figure 7A further solution based on this embodiment is as follows: the conveying assembly includes a second motor 310 fixedly installed on the main body 1 of the device, a conveying roller 311 fixedly connected to the output end of the second motor 310, a transmission wheel 312 fixedly connected to the conveying roller 311, and a transmission belt 313 connected to the transmission wheel 312. The conveying roller 311 is rotatably connected to the main body 1 of the device. The second motor 310 provides stable power to the conveying roller 311. The synchronous rotation of multiple sets of conveying rollers 311 is achieved through the cooperation of the transmission wheel 312 and the transmission belt 313, ensuring that the strip material is subjected to uniform force and moves smoothly during the conveying process.

[0034] Working Principle: This embodiment requires the use of an external sorting machine and an external display terminal. After the external sorting machine cuts the strips, they are conveyed to the main body 1 of the device via its own conveying device. The conveyed strips are photographed by a high-speed camera module 23 and the images are transmitted to the external terminal for observation by the staff. Before the device is started, the rotating disk 213 is rotated, which drives the first threaded rod 212 to rotate within the limiting groove of the mounting plate 22. Since the first threaded rod 212 is threadedly connected to the first fixed bracket 21, the mounting plate 22 will move along the direction of the first guide rod 214 during rotation. The first guide rod 214 slides with the first fixed bracket 21 to provide stable guidance for the mounting plate 22 and prevent it from deviating during movement. To ensure that the mounting plate 22 drives the relevant components to the appropriate height, after the second motor 310 is started, it drives the conveyor roller 311 to rotate. The conveyor roller 311 drives multiple sets of conveyor rollers 311 to rotate synchronously through the transmission wheel 312 and the transmission belt 313, so that the strip material is evenly stressed and moves smoothly on the conveyor roller 311, realizing the continuous conveying of the strip material. When the strip material passes the first fixed bracket 21, the high-speed camera module 23 takes a picture and displays it on the external connection terminal for the staff to observe. When it is necessary to clean the mirror surface of the high-speed camera module 23, the first motor 215 drives the reciprocating screw 216 to rotate. The reciprocating screw 216 cooperates with the rotating block 219. The rotational motion is converted into the reciprocating linear motion of the first sliding block 218. The first sliding block 218 slides smoothly along the second guide rod 217 through the adapted sliding groove, driving the sliding bracket 24 fixed on it to move synchronously back and forth. When the sliding bracket 24 moves, the first gear 25 cooperates with the fixed rack 26, driving the snap-fit ​​assembly, the connecting shaft 27, and the cleaning roller body 28 to rotate, cleaning the mirror surface of the high-speed camera module 23. Air is drawn from the outside by the air pump body 29 and delivered to the air nozzle 210 through the connecting hose 211 to blow away the surface of the high-speed camera module 23, thus replacing manual cleaning of the mirror surface of the high-speed camera module 23. When it is necessary to replace the connecting shaft 27 and the cleaning roller body 28, the first knob 33 is turned to drive the second threaded rod 32 to rotate. Through the threaded transmission, the connecting plate 34, the connecting rod 35 and the fixing rod 36 move. The fixing rod 36 slides along the limiting groove of the second sliding block 37 and pushes the second sliding block 37 to compress the first spring 38, so that the locking block 39 disengages from the connecting shaft 27, releasing the restriction on the connecting shaft 27. After the new connecting shaft 27 and the cleaning roller body 28 are installed on the connecting bushing 31, the first knob 33 is turned to drive the second threaded rod 32 to rotate, which drives the second sliding block 37 and the locking block 39 to reset, so that the locking block 39 re-locks the connecting shaft 27.
