[0026] Example 1, please refer to Figures 1 to 3This is a schematic diagram of a material sorting, positioning, and barcode scanning mechanism provided by this utility model. The material sorting, positioning, and barcode scanning mechanism includes: a feeding conveyor belt 10, a product positioning fixture 40, a barcode scanning and positioning carrier 50 arranged sequentially along the conveying direction, and a double-acting sub-module assembly 30 that feeds the processed product 21 into the product positioning fixture 40 and feeds the box-closing piece 22 into the barcode scanning and positioning carrier 50. It can be imagined that this material sorting, positioning, and barcode scanning mechanism also includes other functional components and specific structures, such as electrical connection components, control components, and installation structures, which are all technologies known to those skilled in the art, and therefore will not be described in detail here.

[0027] In this embodiment, the product frame 20 serves as a conveying carrier, placing the processed product 21 and the sealing strip 22 within it for transfer through various processes. The sealing strip 22 is a film structure and is located at the bottom of the processed product 21. It should be noted that when a single product 21 requires a unique code, the sealing strip 22 can be placed in each product frame 20; when multiple products 21 require a unique code, the sealing strip 22 can be placed in the last of consecutive product frames 20. The product frame 20, the processed product 21, and the sealing strip 22 all tend to have rectangular cross-sections. It should be noted that the structure of the product frame 20, the processed product 21, and the sealing strip 22 themselves has no specific design features, facilitating a detailed explanation in conjunction with the material distribution, positioning, and scanning mechanism.

[0028] The feeding conveyor belt 10 is a conveyor belt structure. Driven by a motor, the feeding conveyor belt 10 transports the product frames 20 from the previous process to the end. The width of the product frames 20 is smaller than the width of the feeding conveyor belt 10, allowing only one product frame 20 to pass through at a time. During transport, the product frames 20 are arranged sequentially along the transport direction. Optimally, the feeding conveyor belt 10 has a positioning frame 11 at the end of the transport direction to allow a single product frame 20 to pass through. The width of the product frame 20 is close to the width of the positioning frame 11, allowing the product frame 20 to accurately enter the positioning frame 11. The inner diameter of the positioning frame 11 gradually decreases along the transport direction. As the product frame 20 enters the end of the feeding conveyor belt 10, it is accurately positioned within the positioning frame 11.

[0029] The dual-action sub-module assembly 30 includes two horizontally sliding structures 31 that slide along the same path and are spaced apart. Each horizontally sliding structure 31 has a vertically sliding structure 32, and a first transfer suction cup 33 and a second transfer suction cup 34 are respectively disposed on the vertically sliding structure 32. Both the first transfer suction cup 33 and the second transfer suction cup 34 are vacuum suction cups and are driven by a cylinder. In this embodiment, the first transfer suction cup 33 is used to adsorb and process the product 21. The size of the first transfer suction cup corresponds to the size of the product 21 to achieve accurate adsorption and prevent movement interference during material handling. Similarly, the second transfer suction cup 34 is used to adsorb and process the sealing plate 22. The size of the second transfer suction cup corresponds to the size of the sealing plate 22 to achieve accurate adsorption and prevent movement interference during material handling. The first transfer suction cup 33 and the second transfer suction cup 34 achieve horizontal displacement through the horizontally sliding structure 31 and vertical displacement through the vertically sliding structure 32, respectively.

[0030] Specifically, the lateral sliding structure 31 includes a horizontally arranged lateral guide rail 311, two lateral sliders 312 slidably disposed on the lateral guide rail 311, and a corresponding lateral actuator 313 that drives the lateral sliders 312 to move along the guide rail. The two lateral actuators 313 are respectively disposed at both ends of the lateral guide rail 311, and the lateral sliders 312 are disposed on the outer side wall of the lateral guide rail 311. The lateral actuator 313 is a cylinder, and drives the two lateral sliders 312 to share the same lateral guide rail 311 for displacement. Utilizing the component installation layout and the versatility of the dual-action sub-module assembly 30 for transferring different materials, the space occupied by the component installation is reduced. The two lateral sliders 312 correspond to the first transfer suction cup 33 and the second transfer suction cup 34, respectively, and the first transfer suction cup 33 and the second transfer suction cup 34 do not interfere with each other during lateral displacement.

[0031] In this embodiment, the vertical sliding structure 32 includes a vertical guide rail 321 disposed on each horizontal slider 312, a vertical slider 322 slidably connected to the vertical guide rail 321, and a vertical driver 323 corresponding to drive the vertical slider 322 to move along the guide rail. The vertical driver 323 is a cylinder and drives the vertical slider 322 to move along the vertical guide rail 321. The first transfer suction cup 33 and the second transfer suction cup 34 are respectively mounted on the vertical slider 322. To ensure installation stability, an angle iron structure is added to the vertical slider 322 to improve structural strength.

[0032] In this embodiment, the product positioning fixture 40 is located on one side of the end of the feeding conveyor belt 10 in the conveying direction. The positioning fixture has a product positioning groove 41 for the processed product 21 to be inserted into. The lateral movement path of the first transfer suction cup 33 is located between the feeding conveyor belt 10 and the product positioning fixture 40. The first transfer suction cup 33 picks up the processed product 21 and transfers it to the product positioning groove 41 for secondary positioning. Specifically, the product positioning fixture 40 includes a product positioning platform 42. A reference positioning frame 43 is provided on the product positioning platform 42. There are two reference positioning frames 43, and their cross-section tends to be L-shaped after being combined. A push-drive block 44 is provided on the product positioning platform 42 and is connected to the reference positioning frame 43. The push-drive block 44 is connected to a cylinder and is located on the corresponding side of the reference positioning frame 43. The space between the reference positioning frame 43 and the push-drive block 44 forms the product positioning groove 41, which has a rectangular groove structure. Optimally, the product positioning platform 42 is provided with spaced and protruding abutment blocks 45. The abutment blocks 45 reduce the contact area between the processed product 21 and the product positioning platform 42 when the processed product 21 is in the product positioning groove 41, making the secondary positioning of the processed product 21 by the abutment drive block 44 smoother and facilitating subsequent secondary gripping. The product platform is also provided with a clearance notch 46, and a sensor 47 is provided in the clearance notch 46. The sensor 47 is an infrared or optical sensor. The sensor 47 identifies whether the processed product 21 is stably in the product positioning groove 41, thereby controlling the driving timing of the abutment drive block 44 to achieve circumferential clamping of the processed product 21.

[0033] In this embodiment, the barcode positioning carrier 50 includes a carrier platform 51 disposed on the side of the product positioning fixture 40 away from the feeding conveyor belt 10. At least two spaced-apart placement frames 52 are provided on the carrier platform 51. A barcode scanner 53 is disposed between the placement frames 52 and the feeding conveyor belt 10, positioned on the side of the carrier platform 51 with its camera facing upwards. The lateral movement path of the second transfer suction cup 34 is located between the feeding conveyor belt 10 and the placement frames 52. When the second transfer suction cup 34 holds the retaining plate 22 and moves towards the placement frame 52, it is pre-braked by the barcode scanner 53 above to complete the barcode scanning before being transferred to the placement frame 52. This allows for tracking of the processing product 21's position and related information during the process. Furthermore, it can be integrated with AOI inspection equipment and AGV carts to achieve automation and improve production efficiency. The added retaining plate 22 enables the recording and conversion of barcode information for single-piece and batch transfers of the processed product 21.

[0034] Specifically, the material placement frame 52 includes four spaced-apart material placement columns 521, with gaps between the four columns 521 providing space for the second material transfer suction cup 34 to vertically convey materials. A positioning notch 522 is provided on the inner side of each column 521, meaning that at the inner corner of each column 521, the outer circumferential wall of the closing piece 22 fits against the inner wall of the positioning notch 522, allowing the closing piece 22 to be accurately stacked within the material placement frame 52. A pad 523, made of bakelite, is provided at the bottom of the material placement frame 52, with the circumferential edge of the closing piece 22 protruding beyond the circumferential edge of the pad 523. When the closing piece 22 is stacked on the pad 523, its circumferential edge is suspended, facilitating subsequent removal and transfer.

[0035] Example 2: This utility model also provides an AOI inspection production line, which has the material sorting, positioning, and barcode scanning mechanism as described above. In addition to the material sorting, positioning, and barcode scanning mechanism, this AOI inspection production line also includes a material transfer robot 60, a feeder 70, and a stacking machine 80 disposed on one side of the product positioning fixture 40. The material transfer robot 60 has one or more working parts, and its output end can adopt either a suction cup structure or a gripping finger. The material transfer robot 60 transfers the processed product 21 located on the product positioning fixture 40 to the feeder 70, and moves the product frame 20 located on the loading conveyor belt 10 to the stacking machine 80. The robot sorts, stores, and transports the processed product 21, the product frame 20, and the retaining plate 22.

[0036] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
