The traction mechanism 23 has a traction rope, and a magnet block is provided at the end of the traction rope. The magnet block is used to magnetically attract the pins of the PCB connecting plates, and to pull the PCB connecting plates on the input station of the slide rail 21 to the output station of the slide rail 21. Among them, the cutting mechanism 22 includes a U-shaped seat 221 and an L-shaped seat 222. The opening of the U-shaped seat 221 is set toward the platform of the machine base 1. The two ends of the U-shaped opening are connected with movable sliders, so that the cutting mechanism 22 moves with the movement of the slide rail 21. A material box 223 for collecting edge materials is provided in the U opening of the U-shaped seat 221. The upper end of the U-shaped seat 221 is connected to the L-shaped seat 222. The inner side of the L-shaped seat 222 facing the slide rail 21 is sequentially provided with a cutting cylinder 224 and a pressing plate cylinder 226.

When the edge material is sheared, the pressing plate cylinder 226 drives the pressing plate 227 to move downward, pressing and fixing the PCB connecting plate on the input station of the slide rail 21. At the same time, the cutting cylinder 224 drives the edge material cutter 225 to move downward, shearing along the stamp connecting hole line of the PCB connecting plate and the edge material, cutting off the edge material of the PCB connecting plate, and the edge material slides into the material box 223 from the inclined wall of the material box 223.

[0036] like Figure 3 、 Figure 5 As shown, a conveying robot 24 is provided on the platform of the machine base 1. A clamping plate 241 is provided at the end of the conveying robot 24 for clamping the PCB joint board on the output station of the slide rail 21 of the edge removal device 2 and conveying it to the first separating device 3 for release. The wide-sized clamping plate 241 can clamp large PCB joint boards, and the conveying efficiency is high.

It includes a flat plate base 31, a baffle 32 mounted on an edge of the flat plate base 31 for limiting the position of the PCB joint board a, and a push plate 33 for pushing the PCB joint board a in translation. A first cutter 34 for shearing the PCB joint board a is provided above the output end of the flat plate base 31. During use, the conveying robot 24 transports the PCB joint board a from the output station of the slide rail 21 of the trimming device 2 to the flat plate base 31 and arranges them in sequence along the baffle 32. Driven by the motor assembly, the push plate 33 pushes the PCB joint board a to the output end of the flat plate base 31. The first cutter 34 moves downward under the action of the cylinder and shears and separates the PCB strips in the first row on the outermost side of the PCB joint board a. Then, as the push plate 33 continues to push, the first cutter 34 shears and separates the PCB strips in the second row, thereby sequentially separating the PCB joint board a into PCB strips.

[0038] like Figure 3 、 Figure 7 、 Figure 8 As shown, the second separating device 4 is used to separate the PCB strips into PCB single boards, and includes a movable rail 41 and a fixed rail 42. The movable rail 41 receives the PCB strips conveyed by the first separating device 3, and the two rows of pins of the PCB strips are downward and located on both sides of the movable rail 41. When the movable rail 41 and the fixed rail 42 are aligned along the length direction of the rails, the PCB strips on the movable rail 41 can be transferred to the fixed rail 42. Specifically, under the action of the mechanical push rod, the PCB strips are pushed to the far end of the fixed rail 42. A second cutter 43 is provided above the far end of the fixed rail 42. Driven by the cylinder, the second cutter 43 cuts the PCB strips one by one into PCB single boards.

It should be noted that the pins of the PCB on the test socket 71 correspond to the needle tips of the probe rows 72. When driven by the motor screw assembly, the probe rows 72 can make the needle tips of the probe rows 72 contact or move away from the pins of the PCB on the test socket 71, which is used for electrical testing of the digital tube circuit board.

[0041] like Figure 1 、 Figure 9 and Figure 10 As shown, the board-covering device 5 includes a PCB board conveyor belt 51 for conveying PCB boards, and a shell conveyor belt 52 located on one side of the PCB board conveyor belt 51 for conveying digital tube shells.

The push rod 613 moves forward or backward under the drive of the hollow motor 614. During use, the digital tube housing delivered from the plate-laying device 5 abuts against the strip-shaped stopper 612. The two ends of the digital tube housing are pushed by the corresponding push rods 613 to arrange and position the digital tube housing so that the heating mechanism 62 can perform hot pressing connection between the PCB and the digital tube housing in the next step.

[0047] like Figure 12 As shown, the heating mechanism 62 includes a lifting motor 621, a heater 622 and a hot melt mold 623. The heater 622 is used to heat the hot melt mold 623, and the lifting motor 621 is used to drive the hot melt mold 623 to descend, so that the lower surface of the hot melt mold 623 is aligned with the melting column of the digital tube shell on the sorting platform 611 for hot pressing, thereby realizing hot pressing welding of the melting column of the digital tube shell and the PCB single board.

[0048] like Figure 2 、 Figure 8 and Figure 13 As shown, a flipping mechanism 8 is provided on one side of the test socket 71 of the test device 7.

[0050] The visual inspection station 11 includes a transparent flat plate arranged parallel to the machine base platform. A camera for shooting upward is arranged at the lower end of the transparent flat plate. The camera is used to collect image information of the bottom of the PCB board on the transparent flat plate.
