When the tray 2 moves to the function detecting device 81, the upper and lower molds 82 and 83 move toward each other, so that the first mold pillar 84 passes through the through hole 21 and is inserted into the mold hole 85, and the second mold pillar 22 is also inserted into the corresponding mold hole 85. The front of the function detection device 81 is provided with a lifting cylinder 88, the lifting cylinder 88 is vertically arranged, a connecting rod 89 is horizontally connected to the cylinder axial direction of the lifting cylinder 88, and the length direction of the connecting rod 89 is the same as the length direction of the slideway 31. One end of the connecting rod 89, which is close to the function detecting device 81, is upwardly connected with a baffle 9. The lifting cylinder 88 drives the connecting rod 89 to move to the highest point, so that the baffle 9 can block the movement of the carrying tray 2. The side of the function detecting device 81 is provided with a detecting cylinder 91, a detecting probe 92 is connected to a piston rod of the detecting cylinder 91, the detecting probe 92 is arranged towards the slideway 31, and when the carrying tray 2 is fixed by the upper die 82 and the lower die 83, the detecting probe 92 can be inserted on a part on the carrying tray 2.
As shown in fig. 11, the final inspection device 11 also has a light shielding plate 41, an illumination lamp 42, and a camera 43, the illumination lamp 42 is provided on the side surface of the slide way 31, the camera 43 is provided near the illumination lamp 42, and the camera 43 is connected to the pc end 44. The camera 43 can collect the picture information of the relay board 26 and the wires 27 and transmit the information to the pc terminal 44. The detection software preset at the pc end 44 can compare the picture acquired by the camera 43 with the standard picture, and determine whether the shapes and the relative positions of the welded relay motherboard 26 and the wire 27 meet the standard.
The using method comprises the following steps: the parts to be soldered are fixed on the carrying tray 2, then the carrying tray 2 is placed on the slide way 31, and two sides of the carrying tray 2 are respectively placed on the conveying belt 32. When the carrying disc 2 passes through the information acquisition device 4, the camera 43 scans the two-dimensional code on the bottom surface of the relay main board 26, then the two-dimensional code information is transmitted to the pc end 44, and the pc end 44 can read the information about the relay main board 26 pre-stored in the two-dimensional code and store the information.
When the carrying tray 2 moves to the first turning device 5, the driving motor 54 rotates forward and drives the fixed belt 52 to move. After the tray 2 is inserted into the slot 53, the tray 2 moves into the roll-over stand 51 by the fixing belt 52. After the carrying disc 2 moves onto the fixed belt 52, the piston rod of the rotating cylinder 13 moves into the rotating cylinder 13 to drive the telescopic rod 14 to move, the telescopic rod 14 is shortened and lengthened in the moving process, and the rotating part 29 is turned over. After the rotating part 29 is turned 180 degrees, the limiting part 19 is abutted against the second limiting block 18, so that the turnover frame 51 and the carrying tray 2 are kept in a horizontal state. At this time, the driving motor 54 is reversed to move the tray 2 out of the roll-over stand 51.
After the tray 2 moves into the welding device 7, the welding gun 71 and the welding wire 74 weld the parts on the tray 2 with the aid of the manipulator 76, the welding wire 74 moves along the feed pipe 72 during welding, and the end of the welding wire 74 moves out along the opening of the feed pipe 72 and contacts the welding gun 71. After the welding is completed, the welding gun 71 and the welding wire 74 return to the original positions, and at this time, the air tap 73 blows air to the welding gun 71 to remove impurities on the welding gun 71.
After the carrier plate 2 is moved out of the welding device 7, it enters the translation device 23. Firstly, the carrying tray 2 enters the translation tray 25, then the translation tray 25 moves on the linear rail 24, the carrying tray 2 is moved to a position close to the second turning device 8, and then the carrying tray 2 is sent out of the translation device 23 by the translation tray 25.
Along the conveyor 3 to the second turning device 8, turned over by the second turning device 8, and then to the function detecting device 81. In the process of moving the carrying tray 2 to the function detecting device 81, the lifting cylinder 88 drives the connecting rod 89 to move upwards, so that the baffle 9 moves to a position capable of blocking the movement of the carrying tray 2. When the carrying disc 2 abuts against the baffle plate 9, the lifting cylinder 88 drives the connecting rod 89 to move downwards, and meanwhile the upper cylinder 86 drives the upper die 82 to move downwards, so that the first die column 84 passes through the through hole 21 and is inserted into the die hole 85; the lower cylinder 87 drives the lower die 83 to move upwards, so that the second die 22 is inserted into the corresponding die hole 85, and the carrying tray 2 is further fixed. At the same time, the probes on the lower die 83 contact the contacts on the relay motherboard 26, and energize the relay motherboard 26. At this time, the detection cylinder 91 drives the detection probe 92 to move toward the tray 2, so that the detection probe 92 is inserted into a part on the tray 2, and the magnetic field of the relevant component on the relay motherboard 26 is detected.
After the function detection, the carrying tray 2 carries the parts through the final detection device 11. The camera 43 at the final inspection device 11 collects the picture information of the relay motherboard 26 and the lead 27 and uploads the picture information to the pc end 44, and the picture information is compared with a standard picture by the detection software in the pc end 44, so as to determine whether the shapes of the relay motherboard 26 and the lead 27 meet the standard.
After the carrying tray 2 comes out of the final inspection device 11, the staff removes the parts such as the relay main board 26 and the lead 27 on the carrying tray 2, so that the empty carrying tray 2 continues to move along the slideway 31. The load disc 2 passes the translation device 23 again and is moved by the translation device 23 onto the other slide 31. At this time, the worker installs the relay motherboard 26 and the lead 27, which are not welded, on the carrying tray 2, and performs welding and detection of the next round, and so on and off in a cycle.
