[0074] In this embodiment, three sets of positioning and labeling mechanisms 4 are arranged sequentially on the side of the station conveying mechanism 2, and are used for chip affixing, front label affixing, and back label affixing respectively. Each set of positioning and labeling mechanisms 4 is followed by a set of vision inspection mechanisms 5, which can detect whether the chip affixing and label affixing of the product is qualified. The flipping mechanism 6 is arranged between the second set of positioning and labeling mechanisms 4 and the third set of positioning and labeling mechanisms 4. After the front label affixing is completed, the flipping mechanism 6 flips the product over for back label affixing.

[0075] Furthermore, the workstation conveying mechanism 2 includes a workstation conveying frame 21, a workstation conveyor belt 22, a workstation conveyor motor 23, and a workstation conveyor transmission module 24. The workstation conveyor belt 22, workstation conveyor motor 23, and workstation conveyor transmission module 24 are all mounted on the workstation conveying frame 21, and the workstation conveyor belt 22 is connected to the workstation conveyor motor 23 via the workstation conveyor transmission module 24. In this application, after the loading mechanism 3 transfers the product onto the workstation conveyor belt 22, the workstation conveyor motor 23 can drive the workstation conveyor belt 22 to rotate on the workstation conveying frame 21 via the workstation conveyor transmission module 24, conveying the product to the corresponding workstations of the positioning and labeling mechanism 4, the vision inspection mechanism 5, and the flipping mechanism 6 for labeling, vision inspection, and flipping. Finally, the product is conveyed to the location of the unloading mechanism 7 for unloading.

[0076] It should be noted that the workstation conveyor transmission module 24 in this embodiment uses conventional standard parts such as transmission belts, transmission wheels, and transmission shafts for transmission, which is existing technology. Its working principle is as follows: transmission shafts are installed at both ends of the conveyor belt, one of which is connected to the transmission wheel through the transmission belt. The transmission wheel is installed on the output shaft of the motor. The workstation conveyor motor 23 can drive the transmission belt and transmission shaft to rotate through the transmission wheel, thereby driving the conveyor belt to rotate.

[0077] Furthermore, the workstation conveyor belt 22 is also equipped with an empty material detection sensor 25. The empty material detection sensor 25 adopts a photoelectric probe and is set between the feeding mechanism 3 and the positioning and labeling mechanism 4. It can detect whether there is a product on the workstation conveyor belt 22. If there is no product, the subsequent mechanisms on the workstation will not operate; if there is a product, the workstation conveyor belt 22 will transport the product to the positioning and labeling mechanism 4 for positioning and labeling.

[0078] Furthermore, the feeding mechanism 3 includes a feeding conveying module 31 for feeding products and a feeding rotary transfer module 32 for transferring products to the workstation conveyor belt 22. The feeding rotary transfer module 32 is disposed between the feeding conveying module 31 and the workstation conveyor belt 22.

[0079] Furthermore, the feeding and conveying module 31 includes a feeding and conveying bracket 311, a feeding and conveying belt 312, a feeding and conveying cylinder 313, and a feeding and conveying transmission module 314. The feeding and conveying belt 312, the feeding and conveying cylinder 313, and the feeding and conveying transmission module 314 are all mounted on the feeding and conveying bracket 311. The feeding and conveying belt 312 is connected to the feeding and conveying cylinder 313 through the feeding and conveying transmission module 314. The feeding and conveying bracket 311 is also provided with a position sensor 315 for detecting whether the product is in place at one end near the feeding and rotating material transfer module 32. In this embodiment, the product is manually placed on the feeding conveyor belt 312. The feeding conveyor cylinder 313 can drive the feeding conveyor belt 312 to move on the feeding conveyor bracket 311, and transport the product to the position of the feeding rotary transfer module 32. When the product is in place, the position sensor 315 uses a photoelectric probe to detect it and transmits the detection signal to the control system. The control system controls the feeding rotary transfer module 32 to work and transfer the product to the workstation conveyor belt 22.

[0080] In this embodiment, the feeding and conveying transmission module 314 achieves transmission through the cooperation of a rotating shaft, a swing wheel, and a transmission shaft, which is existing technology. Its working principle is as follows: the rotating shaft is connected to the output end of the feeding and conveying cylinder 313, and there are two transmission shafts, which are respectively installed at both ends of the conveyor belt. One end of the swing wheel is connected to the rotating shaft, and the other end is fixedly connected to one of the transmission shafts.

The vacuum suction cup 326 is set at the output end of the linear cylinder 325, and the end of the vacuum suction cup 326 facing away from the linear cylinder 325 is directly opposite the end opening of the feeding conveyor belt 312. In this embodiment, when the product arrives at its designated position, the control system activates the linear cylinder 325. The linear cylinder 325 pushes the vacuum suction cup 326 to the end opening of the feeding conveyor belt 312, adsorbing and gripping the product conveyed by the feeding conveyor belt 312. The linear cylinder 325 retracts, and then the rotary cylinder 322 rotates 90 degrees, rotating the product above the station conveyor belt 22. The vacuum suction cup 326 is released, and the product falls onto the station conveyor belt 22. As the station conveyor belt 22 moves to various stations, the rotary cylinder 322 rotates 90 degrees in the opposite direction, and the linear cylinder 325 continues to push the vacuum suction cup 326 to grip the product.

[0085] In this embodiment, an unlabeled labeling tape 413 is placed on the take-up roller 416. The take-up roller 416 is used to retrieve the labeling tape 413 that has been labeled. The chip or label is attached to the labeling tape 413. The labeling drive motor 4121 can drive the drive roller 415 to rotate through the synchronous belt 4123 and the guide wheel. Since the labeling tape 413 is pressed against the drive roller 415 by the pressure roller 417, it will move forward under the drive of the drive roller 415, conveying the chip or label forward. When the labeling tape 413 moves forward, it will pull the unwinding roller 414 to unwind synchronously, and the take-up roller 416 will also rewind synchronously. When it is conveyed to the position of the labeling plate 418, the labeling cylinder 419 pushes the labeling plate 418 forward, pushing the chip or label to the labeling position for labeling.
