Description

Technical Field

[0001] This invention relates to the field of visual recognition technology, and more specifically to an automatic information recognition device. Background Technology

[0002] During the smartwatch manufacturing process, characters are laser-etched into the grooves of the watch band. Typically, these characters are manually observed and compared with the content displayed on the smartwatch screen to determine if they match the information recorded in the smartwatch's internal software. This method is not only inefficient but also prone to human error, which in turn affects the efficiency and accuracy of the production line.

[0003] Chinese patent CN212228759U discloses a mobile phone cover plate inspection device, including a frame with a product station, and a first camera, a third camera, a third light, a fourth camera, a coaxial light source, a tunnel light source, a four-sided adjustable light source, and a backlight light source mounted on the frame. The first camera is located directly above the product station. A coaxial light source and a tunnel light source are arranged between the first camera and the product station, with the coaxial light source shining through a hole in the tunnel light source onto the product station. The third camera is tilted and located diagonally above the product station. The third light corresponds to the third camera. The fourth camera is located directly below the product station. The four-sided adjustable light source is located between the product station and the fourth camera. The backlight light source is located between the four-sided adjustable light source and the fourth camera, with the backlight light shining through an opening in the center of the four-sided adjustable light source onto the product station. Through this method, the device can perform comprehensive inspection of the appearance of mobile phone cover plates, with high inspection efficiency and accuracy. However, this inspection device still has the following problems: 1. The operation of this testing equipment is relatively inconvenient. When loading and unloading workpieces, the testing structure needs to be stopped and wait, resulting in low testing efficiency and making it unsuitable for batch continuous testing of electronic equipment. 2. The sides of smartwatches typically have openings for sensors to directly contact the external environment, such as BRB openings, used by barometric pressure sensors to measure air pressure. However, these openings can reflect light and interfere with image recognition, reducing the accuracy of the recognition results.

[0004] Based on this, the present invention designs an automatic information identification device to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automatic information identification device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automatic information identification device, comprising a rack; The frame is equipped with a tooling mechanism and a combined optical vision recognition mechanism, and the barcode scanner is fixedly mounted on the frame by a bracket; the tooling mechanism consists of several sets of loading components. The loading assembly includes a moving assembly, a support platform, a tooling assembly, and a flip-type shielding assembly. The moving assembly is mounted on the upper end of the frame, and the moving end of the moving assembly is fixedly mounted on the support platform. The tooling assembly and the flip-type shielding assembly are mounted on the support platform. The flip-type shielding assembly is used to shield the reflective parts of the workpiece to avoid interfering with the recognition results of the combined optical vision recognition mechanism. By operating multiple sets of loading assemblies simultaneously, while one loading assembly is carrying the workpiece for photo recognition, other loading assemblies are performing loading and unloading operations, thereby eliminating the idle waiting time of traditional single-station equipment and effectively improving the recognition efficiency of the workpiece. Compared with single-station equipment, this design can improve efficiency by more than 85% through parallel processing. The number of loading assemblies can be expanded to more than four sets, arranged in a circular or linear distribution. When the workpiece is loaded into the tooling assembly, the moving assembly moves the tooling assembly to the lower side of the combined optical vision recognition mechanism 3, and at the same time, the flip-type shielding assembly shields the BRB holes on both sides of the workpiece to avoid the reflection of the BRB holes interfering with the photo recognition, ensuring the accuracy of the recognition results.

[0007] The moving component includes a Y-axis linear module and an X-axis linear module. The Y-axis linear module is fixedly connected to the frame, and the X-axis linear module is fixedly installed at the moving end of the Y-axis linear module. A support platform is fixedly installed at the moving end of the X-axis linear module. The Y-axis linear module and the X-axis linear module work together to control the movement of the workpiece on the horizontal plane. The Y-axis linear module and the X-axis linear module can be lead screw linear modules, synchronous belt linear modules, etc., but they lack the precision of workpiece conveying.

[0008] The barcode scanner is mounted on the frame via a position fine-tuning assembly, which includes a three-axis fine-tuning stage consisting of three linear slides and a mounting plate. The linear slides can be hand-cranked screw slides. The barcode scanner is mounted on the moving end of the hand-cranked screw slide via the mounting plate and fasteners. The mounting angle of the barcode scanner can be changed. Thus, through the cooperation of the three-axis fine-tuning stage and the mounting plate, the barcode scanner can have three translational degrees of freedom and one rotational degree of freedom to meet the recognition requirements of workpieces of different sizes and with different placement postures.

[0009] Furthermore, the tooling assembly includes an adsorption component and a contouring tooling block. The adsorption component is fixedly mounted on the upper end of the support platform, and the contouring tooling block that mates with the workpiece is fixedly mounted on the adsorption component. The contouring tooling block is 3D printed according to the outer contour of the workpiece and has a built-in rubber buffer layer to prevent damage to the workpiece. The adsorption component integrates a pressure sensor, and the adsorption force is adjusted by the pressure sensor to effectively prevent the workpiece from falling off.

[0010] Furthermore, the inner side of the adsorption component has a through groove for the workpiece screen to protrude, and the adsorption component is tilted so that the scanning end of the barcode scanner is perpendicular to the adsorption component, which makes it easier for the barcode scanner to read the content of the workpiece screen, avoids the light refraction error of traditional horizontal barcode scanning, and improves the recognition accuracy.

[0011] Furthermore, the flip-type shielding assembly includes a flipping assembly and a shielding assembly. The flipping assembly is mounted on a support platform, and the shielding assembly for shielding the watch strap groove of the workpiece is installed on the flipping assembly.

[0012] Furthermore, the flipping assembly includes a rotary drive, a rotary shaft, a bracket, and a swing plate. The rotary drive and the bracket are mounted on a support platform. The rotary shaft is rotatably connected to the bracket via a bearing. The output end of the rotary drive is driven to the rotary shaft. The swing plate is fixedly connected to the rotary shaft. The rotary drive component includes a stepper motor and a transmission assembly. The stepper motor is fixedly installed at the lower end of the support platform. The output end of the stepper motor is connected to the rotary shaft through the transmission assembly. The transmission assembly can adopt a synchronous belt and synchronous pulley transmission structure. The stepper motor is driven by a synchronous belt with a 3:1 reduction ratio to drive the rotary shaft and rotate the swing plate from 0 to 90 degrees.

[0013] The end of the rotating shaft is equipped with a rotation angle limiting component. There are two sets of rotation angle limiting components, which are used to limit the fully open and fully closed states of the swing plate respectively. The rotation angle limiting component includes a limiting block and a limiting seat. The limiting block is fixedly connected to the rotation shaft, and the limiting seat is fixedly connected to the support platform. By using the blocking effect of the limiting seat on the limiting block, the rotation angle of the swing plate can be controlled. A position sensor can also be set to further determine whether the limiting block is correctly positioned.

[0014] Furthermore, the shielding component includes a push drive and a contour block. The push drive is fixedly connected to the swing plate, and the output end of the push drive is fixedly installed with a contour block for shielding the strap groove. The surface of the contour block is coated with a black matte ceramic layer to further absorb stray light. The push drive can be a dual-axis cylinder to achieve the linear movement effect of the contour block. By placing the workpiece on the adsorption component, with the screen of the workpiece facing one side of the adsorption component and located in the through groove, and the workpiece being limited by the contour tooling block, the Y-axis linear module and the X-axis linear module work together to drive the workpiece to move towards the combined light vision recognition mechanism. During this process, the contour block engages with the strap groove of the workpiece, shielding the BRB holes on both sides of the workpiece. Furthermore, the combined optical vision recognition mechanism includes a camera module, a mounting frame, a crossbeam, and a combined light source assembly. A crossbeam is fixedly mounted on the frame, and a camera module is fixedly mounted on the upper end of the crossbeam, with the camera module being vertically positioned. A mounting frame is fixedly mounted on the top of the crossbeam, and a combined light source assembly is mounted on the lower end of the mounting frame.

[0015] Furthermore, the combined light source assembly includes a first light source for eliminating specular reflection interference, a second light source for providing uniform shadowless illumination, and a third light source for providing high-intensity local illumination. The second light source is installed at the lower end of the mounting bracket, the first light source is fixedly installed at the upper end of the second light source, and the third light source is symmetrically fixedly installed on the side of the second light source. The lower end of the mounting bracket is provided with an arc-shaped groove, and the second light source is installed at the lower end of the mounting bracket by fasteners such as bolts cooperating with the arc-shaped groove. By changing the position of the bolts in the arc-shaped groove, the installation angle of the second light source can be changed.

[0016] Furthermore, there are two third light sources, symmetrically distributed on the left and right sides of the second light source.

[0017] The first, second, and third light sources employ a coaxial light source, a bowl light source, and a point light source, respectively. Once the workpiece is positioned under the camera module, the barcode scanner scans the workpiece screen information, and the camera module captures and identifies the characters. During camera capture, the bowl light source provides uniform diffuse illumination, eliminating reflections, shadows, and texture interference. The coaxial light source, coaxial with the camera module, covers the workpiece, eliminating specular reflection interference. The point light source provides a high-brightness, highly directional beam to precisely highlight edge contours. The combined lighting of these three sources ensures clearer and faster character recognition, improving equipment efficiency and accuracy. This system is compatible with products made of various materials, and the light source ratio can be adjusted according to the workpiece material. For example, for metal materials, the coaxial light accounts for 70%; for ceramic materials, the bowl light source accounts for 80%.

[0018] To better achieve the objectives of this invention, this invention also provides a method for using an automatic information identification device, comprising the following steps: Step 1: Place the workpiece on the tooling assembly, with the screen of the workpiece facing the tooling assembly, and the workpiece is limited by the tooling assembly; Step 2: Block the BRB holes on both sides of the workpiece using the flip-type blocking assembly; Step 3: The moving component drives the workpiece toward the combined optical vision recognition mechanism until the workpiece is located below the camera module; Step 4: The barcode scanner scans the information on the workpiece screen; Step 5: Illuminate the workpiece using a combination of light source components, and then use a camera module to take pictures and recognize characters; Step Six: Compare whether the information read by the camera module and the barcode scanner are consistent.

[0019] Compared with the prior art, the beneficial effects of this invention are as follows: 1. This invention uses multiple loading components to operate simultaneously. While one loading component is carrying the workpiece for photo recognition, other loading components are performing loading and unloading operations, thereby eliminating the idle waiting time of traditional single-station equipment and effectively improving the recognition efficiency of the workpiece. Compared with single-station equipment, this design can improve efficiency by more than 85% through parallel processing. The number of loading components can be expanded to more than four groups, arranged in a circular pattern. After the workpiece is loaded into the tooling component, the moving component moves the tooling component to the lower side of the combined light vision recognition mechanism 3. At the same time, the flip-type blocking component blocks the BRB holes on both sides of the workpiece to avoid BRB hole reflections interfering with photo recognition, thereby effectively eliminating the image overexposure problem caused by BRB hole metal reflections, reducing the probability of character recognition misjudgment, and ensuring the accuracy of the recognition results.

[0020] 2. Once the workpiece is positioned under the camera module, the barcode scanner scans the workpiece screen information, and the camera module takes a picture to identify the characters. While the camera module is taking the picture, the bowl-shaped light source provides uniform diffuse illumination, eliminating reflections, shadows, and texture interference. The coaxial light source is coaxial with the camera module, covering the workpiece to eliminate specular reflection interference. The point light source provides a high-brightness, highly directional beam to accurately highlight edge contours. The combined lighting of these three sources ensures clearer and faster character recognition, improving equipment efficiency and accuracy. Furthermore, the light source ratio can be adjusted according to the workpiece material to enhance the concave and convex contours of the characters, making it suitable for products made of different materials. The lower end of the mounting bracket has an arc-shaped groove. The bowl-shaped light source is installed at the lower end of the mounting bracket using bolts and other fasteners. By changing the position of the bolts within the arc-shaped groove, the installation angle of the bowl-shaped light source can be changed.

[0021] 3. The contour-following fixture is 3D printed according to the outer contour of the workpiece and has a built-in rubber buffer layer to prevent damage to the workpiece. The inner side of the suction unit has a through groove for the workpiece screen to protrude, and the suction unit is tilted so that the scanner's scanning end is perpendicular to the suction unit, facilitating the scanner's reading of the workpiece screen content and avoiding the light refraction errors of traditional horizontal scanning, thus improving recognition accuracy. The suction unit can integrate a pressure sensor, which can be used to adjust the suction force to prevent the workpiece from falling off. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] In some embodiments, please refer to the accompanying drawings. Figures 1-10 An automatic information identification device, comprising a frame 1; The frame 1 is equipped with a tooling mechanism 2 and a combined optical vision recognition mechanism 3. The combined optical vision recognition mechanism 3 is located on the upper side of the tooling mechanism 2; the barcode scanner 4 is fixedly mounted on the frame 1 by a bracket; the tooling mechanism 2 is composed of several sets of loading components, and at least two loading components are provided and evenly distributed on the lower side of the combined optical vision recognition mechanism 3; The loading assembly includes a moving assembly, a support platform 23, a tooling assembly, and a flip-type shielding assembly. The moving assembly is installed on the upper end of the frame 1, and the moving end of the moving assembly is fixedly installed with the support platform 23. The tooling assembly and the flip-type shielding assembly are installed on the support platform 23.

[0028] This invention employs multiple loading components operating simultaneously. While one loading component is performing image recognition on a workpiece, the other loading components are performing loading and unloading operations, thereby eliminating the idle waiting time of traditional single-station equipment and effectively improving the workpiece recognition efficiency. Compared to single-station equipment, this design can improve efficiency by more than 85% through parallel processing. The number of loading components can be expanded to more than four, arranged in a circular or linear distribution. After the workpiece is loaded into the fixture assembly, the moving assembly moves the fixture assembly to the underside of the combined light vision recognition mechanism 3. At the same time, the rotating shielding assembly blocks the BRB holes on both sides of the workpiece to prevent the BRB holes from reflecting light and interfering with the photo recognition, thus ensuring the accuracy of the recognition results.

[0029] In some embodiments, please refer to Figure 4 The barcode scanner 4 is mounted on the frame 1 via a position fine-tuning assembly. The position fine-tuning assembly includes a three-axis fine-tuning stage consisting of three linear slides and a mounting plate. The linear slides can be hand-cranked screw slides. The barcode scanner 4 is mounted on the moving end of the hand-cranked screw slide via the mounting plate and fasteners. The mounting angle of the barcode scanner 4 can be changed. Thus, through the cooperation of the three-axis fine-tuning stage and the mounting plate, the barcode scanner 4 can have three translational degrees of freedom and one rotational degree of freedom to meet the recognition operation of workpieces of different specifications and different placement postures.

[0030] Please see Figures 7-10 The moving assembly includes a Y-axis linear module 21 and an X-axis linear module 22. The Y-axis linear module 21 is fixedly connected to the frame 1. The X-axis linear module 22 is fixedly mounted on the moving end of the Y-axis linear module 21, and a support platform 23 is fixedly mounted on the moving end of the X-axis linear module 22. The Y-axis linear module 21 and the X-axis linear module 22 work together to control the movement of the workpiece on the horizontal plane. The Y-axis linear module 21 and the X-axis linear module 22 can be ball screw linear modules, synchronous belt linear modules, etc. The tooling assembly includes an adsorption component 24 and a contouring tooling block 25. The adsorption component 24 is fixedly mounted on the upper end of the support platform 23, and the contouring tooling block 25, which mates with the workpiece, is fixedly mounted on the adsorption component 24. The contouring tooling block 25 is 3D printed according to the outer contour of the workpiece and has a built-in rubber buffer layer to prevent damage to the workpiece. A through groove is opened on the inner side of the adsorption component 24 to allow the workpiece screen to protrude, and the adsorption component 24 is tilted so that the scanning end of the barcode scanner 4 is perpendicular to the adsorption component 24, which facilitates the barcode scanner 4 in reading the content of the workpiece screen, avoids the light refraction error of traditional horizontal barcode scanning, and improves the recognition accuracy. The adsorption component 24 can be a vacuum suction cup with an integrated pressure sensor. The adsorption force can be adjusted by the pressure sensor to prevent the workpiece from falling off.

[0031] The flip-type shielding assembly includes a flipping component and a shielding component. The flipping component is mounted on the support platform 23, and the flipping component is equipped with a shielding component for shielding the watch strap groove of the workpiece.

[0032] The flipping assembly includes a rotary drive, a rotary shaft 28, a bracket 29, and a swing plate 210. The rotary drive and the bracket 29 are fixedly installed on the upper end of the support platform 23. The output end of the rotary drive is driven to the rotary shaft 28, and the swing plate 210 is fixedly connected to the rotary shaft 28. The rotary drive component includes a stepper motor 26 and a transmission assembly 27. The stepper motor 26 is fixedly installed at the lower end of the support platform 23. The output end of the stepper motor 26 is connected to the rotary shaft 28 through the transmission assembly 27. The transmission assembly 27 can adopt a synchronous belt and synchronous pulley transmission structure. The swing plate 210 is fixedly connected to the rotary shaft 28. The stepper motor 26 is driven by the synchronous belt with a speed reduction ratio of 3:1, which drives the rotary shaft 28 to rotate the swing plate 210 from 0 degrees to 90 degrees.

[0033] Please see Figure 10 The end of the rotating shaft 28 is equipped with a rotation angle limiting component. There are two sets of rotation angle limiting components, which are used to limit the fully open and fully closed states of the swing plate 210 respectively. The rotation angle limiting component includes a limiting block and a limiting seat. The limiting block is fixedly connected to the rotation shaft 28, and the limiting seat is fixedly connected to the support platform 23. By blocking the limiting block through the limiting seat, the rotation angle of the swing plate 210 can be controlled. A position sensor can also be set to further determine whether the limiting block is correctly positioned.

[0034] The shielding assembly includes a cylinder 211 and a contour block 212. The cylinder 211 is fixedly connected to the swing plate 210, and the output end of the cylinder 211 is fixedly installed with a contour block 212 for shielding the groove of the watch strap.

[0035] Furthermore, the surface of the contour block 212 is coated with a black matte ceramic layer to further absorb stray light.

[0036] In this invention, the workpiece is placed on the adsorption member 24, with the screen of the workpiece facing the adsorption member 24 and located in the through groove. The workpiece is limited by the contouring tooling block 25. During the process of the Y-axis linear module 21 and the X-axis linear module 22 moving the workpiece towards the combined optical vision recognition mechanism 3, the stepper motor 26 drives the rotating shaft 28 to rotate through the transmission assembly 27. This, in turn, drives the cylinder 211 to swing towards the adsorption member 24 through the swing plate 210 until the swing plate 210 abuts against the workpiece. Subsequently, the cylinder 211 drives the contouring stop block 21. 2. Retracting the guide block 212 engages with the strap groove of the workpiece, blocking the BRB holes on both sides of the workpiece. This effectively eliminates the image overexposure problem caused by metal reflection from the BRB holes, reduces character recognition errors, and allows other loading and unloading operations to be performed while the workpiece on one loading component is being photographed and recognized. This eliminates the idle waiting time of traditional single-station equipment and effectively improves the recognition efficiency of workpieces. Compared with single-station equipment, the parallel processing of workpieces in this design can effectively improve the recognition efficiency of batch workpieces.

[0037] In some embodiments, please refer to Figure 5 , Figure 6 and Figure 11 The combined optical vision recognition mechanism 3 includes a camera module 31, a mounting frame 32, a combined light source assembly, and a cross frame 36. The cross frame 36 is fixedly installed on the frame 1. The camera module 31 is fixedly installed at the upper end of the cross frame 36 and is vertically arranged. The mounting frame 32 is fixedly installed at the top of the cross frame 36 and the combined light source assembly is installed at the lower end of the mounting frame 32. The combined light source assembly includes a first light source 33 for eliminating specular reflection interference, a second light source 34 for providing uniform shadowless illumination, and a third light source 35 for providing high-intensity local illumination. The second light source 34 is installed at the lower end of the mounting bracket 32, the first light source 33 is fixedly installed at the upper end of the second light source 34, and the third light source 35 is symmetrically fixedly installed on the side of the second light source 34. There are two third light sources 35, which are symmetrically distributed on the left and right sides of the second light source 34.

[0038] The first light source 33 is a coaxial light source, the second light source 34 is a bowl light source, and the third light source 35 is a point light source. The lower end of the mounting bracket 32 ​​is provided with an arc-shaped groove. The bowl light source is installed at the lower end of the mounting bracket 32 ​​by fasteners such as bolts and fitting into the arc-shaped groove. By changing the position of the bolts in the arc-shaped groove, the installation angle of the bowl light source can be changed.

[0039] Bowl light source: a hemispherical diffuser with a diameter of 180mm, containing 216 high color rendering index LEDs (Ra≥95), with continuously adjustable illuminance (0-50000Lux).

[0040] Point light source: 1 set of 3W COB integrated light source on each side, horizontal distance from the bowl light source: 0-50mm adjustable, angle 45°±30° adjustable.

[0041] The distance between the workpiece and the bowl light source is adjustable from 0 to 10 mm.

[0042] in: Coaxial light source: mounted 10±5mm directly above the bowl light source, using a ring LED (256 SMD LEDs, color temperature 6500K±300K)), the light is projected vertically onto the workpiece surface through a beam splitter. Bowl-shaped light source: a hemispherical diffuser with a diameter of 180mm, containing 216 high color rendering index LEDs (Ra≥95), with continuously adjustable illuminance (0-50000Lux). Point light source: 1 set of 3W COB integrated light source on each side, horizontal distance from the bowl light source: 0-50mm adjustable, angle 45°±30° adjustable; In this invention, the workpiece is placed on the adsorption member 24, with the screen of the workpiece facing the adsorption member 24 and located in the through groove. The workpiece is limited by the contouring tooling block 25. During the process of the Y-axis linear module 21 and the X-axis linear module 22 working together to move the workpiece toward the combined light vision recognition mechanism 3, the contouring block 212 engages with the strap groove of the workpiece to block the BRB holes on both sides of the workpiece. Once the workpiece is positioned under the camera module 31, the barcode scanner 4 scans the workpiece screen information, and the camera module 31 takes a picture to identify the characters. While the camera module 31 is taking pictures, the bowl light source provides uniform diffuse illumination to eliminate reflections, shadows, and texture interference; the coaxial light source is coaxial with the camera module 31 and covers the workpiece to eliminate specular reflection interference; the point light source provides a high-brightness, highly directional beam to accurately highlight the edge contours; the three lights work together to make the characters clearer and faster to be identified, improving equipment efficiency and accuracy, and can be used for products of different materials.

[0043] In some embodiments, when illuminating the workpiece, the workpiece is first pre-scanned, the bowl light source is activated at 30% brightness to obtain a global positioning image of the workpiece, and then the coaxial light source is turned on at full power to eliminate the mirror reflection of the screen glass. At the same time, the point light source illuminates the edge of the workpiece at a 45° tilt angle to enhance the concave and convex contours of the characters. The proportion of the light source is adjusted according to the material of the workpiece. For example, for metal materials, the coaxial light accounts for 70%; for ceramic materials, the bowl light source accounts for 80%.

[0044] like Figure 1-11 As shown, in a preferred embodiment of the present invention, a method for using an automatic information identification device is also provided, comprising the following steps: Step 1: Place the workpiece on the suction member 24 of the tooling assembly of the tooling mechanism 2, with the screen of the workpiece facing the suction member 24 and located in the through groove, and the workpiece is limited by the contour tooling block 25 of the tooling assembly of the tooling mechanism 2. Step 2: The stepper motor 26 of the flip-type shielding component of the tooling mechanism 2 drives the rotating shaft 28 of the flip-type shielding component of the tooling mechanism 2 to rotate through the transmission component 27 of the flip-type shielding component of the tooling mechanism 2. In turn, the cylinder 211 of the flip-type shielding component of the tooling mechanism 2 drives the swing plate 210 of the flip-type shielding component of the tooling mechanism 2 to swing towards the adsorption component 24 until the swing plate 210 abuts against the workpiece. Step 3: Cylinder 211 drives the contour block 212 of the flip-type blocking assembly of tooling mechanism 2 to retract, so that the contour block 212 engages with the strap groove of the workpiece, blocking the BRB holes on both sides of the workpiece. Step 4: The Y-axis linear module 21 and X-axis linear module 22 of the moving component of the tooling mechanism 2 work together to move the workpiece towards the direction of the combined optical vision recognition mechanism 3 to the underside of the camera module 31. Step 5: The barcode scanner 4 scans the workpiece screen information; Step Six: The combined light source components of the combined light vision recognition mechanism 3 work together to illuminate the image, and the camera module 31 takes a picture to recognize the character. Step 7: Compare whether the information read by the camera module 31 and the barcode scanner 4 are consistent.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
