8. An assembly method for a DBC side frame assembly device, specifically including the following steps: Step 1: The staff puts the pallet with the side frame into the side frame feed port (31) of the side frame transport channel (3). The side frame pallet enters the position of the side frame lifting platform (32) through the track of the side frame feed port (31). The lifting motor of the side frame lifting platform (32) drives the side frame lifting platform (32) to transport the side frame pallet to the top. The robot (6) grabs the side frame on the side frame pallet and transports it to the transport device (712) of the laser marking mechanism (71). Step 2: Place the transport device (712) outside the dust cover (711), and use the robot (6) to transport the side frame to the marking platform of the transport device (712). Use the inspection camera on the inspection frame on the side of the transport device (712) to determine the position of the side frame on the marking platform. Then move the transport device (712) into the dust cover of the dust cover (711), and move the marking platform into the limiting plate of the dust cover (711) and attach it to the limiting groove. The front end is covered by a dust baffle. Cover protection, start the laser marking machine, mark the side frame inside the dust cover through the marking port. During the marking process, it can effectively block dust from entering and laser from being emitted. After the marking is completed, the transport device (712) moves the marking platform and side frame out of the dust cover (711) again. The barcode scanner on the inspection frame scans and inspects the marking results. The robot (6) grabs the products that pass the marking inspection onto the central turntable (5) and grabs the products that fail the inspection onto the NG tray of the NG channel (4). Step 3: Transport the side frame to the weighing platform (7212) of the coating and glue applicator (72) via the central turntable (5), place the side frame on the glue applicator plate (72123), and at this time, the weighing scale (72122) connected to the bottom of the glue applicator plate (72123) starts counting and measures the weight of the side frame at this time as M1; find the glue application positions of the side frame, move the X-axis positioning structure of the two-axis positioning device (7211) to position the glue application position of the side frame in the X-axis direction, move the Y-axis positioning structure of the two-axis positioning device (7211) to position the glue application position of the side frame in the Y-axis direction, after positioning, apply glue to the side frame with a glue gun, and at the same time, the weighing scale (72122) measures the weight change on the glue applicator plate (72123) as M2. The difference between M2 and M1 is the weight of the glue application. Use this weight to determine whether the glue application is excessive or insufficient. Step 4: The substrate tray enters from the substrate inlet (21) of the substrate transport channel (2). The robot (6) on the right side grabs the module substrate on the substrate tray and places it on the first flipping mechanism (11) to swap the front and back of the substrate. The robot (6) then picks up the module substrate after swapping the front and back and places it in the second assembly part (72223) of the closing device (72223).Step 5: After the glue is applied, the glued side frame is transported to the first assembly part (72222) of the mounting platform (7222) of the flipping and closing device (722) by the central turntable (5). The outer line flips the module substrate 180 degrees and places it on the second assembly part (72223). The X-axis flipping structure of the three-axis flipping device (7221) moves and determines the X-axis position of the module substrate by the vision locator. The Y-axis flipping structure of the three-axis flipping device (7221) moves and determines the Y-axis position of the module substrate by the vision locator. Finally, the A-axis flipping structure of the three-axis flipping device (7221) positions the angle of the module substrate and completes the assembly. The robot (6) picks up the assembled and glued products that are not qualified and puts them on the NG tray of the NG channel (4) on the right. The central turntable (5) picks up the qualified products and puts them on the packaging platform (733) of the substrate packaging mechanism (73). Step Six: Position and fix the substrate using the positioning holes (7332) on the packaging platform (733). After fixing the substrate, move the three-axis packaging device (731). First, position the X-axis of the packaging head using the X-axis packaging structure, then adjust and position the Z-axis height of the packaging head using the Z-axis packaging structure, and finally adjust and position the Y-axis of the packaging head using the Y-axis packaging structure to ensure that the packaging head reaches above the substrate on the packaging platform (733). Start the suction pipe (7321) to reach the loading hole (733) of the packaging platform (733). At position 331), the encapsulation screw in the encapsulation storage tank (7333) is sucked up from the loading hole (7331) and placed in the position to be tightened. Then the encapsulation head is moved to the position, and the encapsulation rotation motor is started to control the encapsulation head to tighten the screw. Each set position is fixed in sequence. When the screw is damaged or the size is wrong, the suction pipe (7321) drops the unusable screw into the waste tank. When different types of screws need to be encapsulated, the central turntable (5) transports the substrate to the second substrate encapsulation mechanism (73) and performs this step again. Step 7: The robot (6) on the left clamps the encapsulated substrate onto the second flipping mechanism (12) to flip the substrate. After the flipping is completed, the robot (6) clamps the substrate onto the side frame tray on the side frame lifting platform (32). After the side frame tray is loaded, the side frame tray is transported out from the side frame outlet (33), and the substrate tray is transported out from the substrate outlet (22).
