When the carrier plate 135 is stacked on the base plate 134, tightening the locking bolts 1352 inserts them into the locking holes 1342, locking the carrier plate 135 onto the base plate 134. A QR code 1353 corresponding to the product model is provided on the carrier plate 135. The assembly equipment includes multiple barcode scanners, which can read the information from the QR code 1353 on the carrier plate 135 to select the corresponding program or accessory, etc. The carrier plate 135 is also provided with one or more handles 1354 to facilitate the loading and unloading of the carrier plate 135.

[0056] The assembly equipment has a co-line assembly mode. In the co-line assembly mode, the carrier plates 135 on the base plates 134 of multiple carriers 13 on the frame 11 are different. At least one carrier plate 135 corresponds to a first type of vehicle and pedestrian warning device, and at least another carrier plate 135 corresponds to a second type of vehicle and pedestrian warning device. The QR codes on the two types of carrier plates 135 are different to correspond to different product models. A barcode scanner 114 is installed on the frame 11 of the upper and lower shell feeding mechanism 2, the laser engraving mechanism 3, the control circuit board feeding mechanism 4, the screw fastening mechanism 5, the glue dispensing mechanism 6, the glue dispensing detection mechanism 7, the automatic pressing mechanism 8, and the unloading mechanism 9, or on the frame 11 adjacent to these mechanisms. The barcode scanner 114 reads the QR code on the carrier plate 135. After parsing the product model corresponding to the QR code, the above mechanisms determine whether to run, or select the movement path of their respective robotic arms (such as the PCB picking robotic arm, the glue dispensing robotic arm, the screw fastening robotic arm, etc.), or select the pressing depth of the pressure plate 81, or select the QR code information laser engraved on the lower shell of the product, etc.

[0057] The assembly equipment described in this embodiment can support the simultaneous production of multiple models on the same line. Different models of vehicle-mounted pedestrian warning devices can be produced simultaneously on the same line, thereby improving the flexibility of the assembly equipment and increasing production line efficiency. The simultaneous production of multiple models can be achieved by quickly changing different carrier plates 135; product differentiation and production process tracking can be achieved by scanning the QR codes on different models of carrier plates 135.
