[0027] like Figure 1 , Figure 2 and Figure 5 As shown, one end and the other side of the middle of the strip plate 10 are respectively fixedly connected to the corresponding side windows 101 on both sides of the chassis 1, and three oil cylinders 2 4 are equidistantly installed on both sides of the top of the chassis 1, and the push rod ends of the three oil cylinders 2 4 in the same group are fixedly connected to the top of the U-shaped plate 1 2 located in the chassis 1, and the side walls on both sides of the U-shaped plate 1 2 are respectively fixedly connected to the cylinder body parts of the corresponding oil cylinders 1 3;

[0028] The strip plate 10 is provided with strip grooves 1001 on both the upper and lower sides, and transmission wheels 16 are rotatably installed at both ends of the strip grooves 1001. The four transmission wheels 16 distributed in a matrix are in transmission contact with the same magnetized conveyor belt 9, and the shaft end of one side of one of the transmission wheels 16 is connected to the built-in electric driver, and the surface of the magnetized conveyor belt 9 exceeds the notch of the strip grooves 1001;

[0029] The strip plate 10 is provided with a certain length, and a magnetized conveyor belt 9 of a certain length can be installed to form a structural function of continuously conveying electronic components. The oil cylinder 2 4 and the oil cylinder 1 3 are used to adjust the position of the pressing strip block 7 and the pin line pressing plate 8.

[0030] like Figure 1 and Figure 3As shown, strip guide rods 12 are fixedly installed at the bottom of both sides of the rectangular hole 1002, and the strip guide rods 12 are slidably connected to the guide grooves 1101 at the bottom of the same side of the two pin wire pushing plates 11; the two ends of the strip guide rods 12 are fixedly connected to the corresponding parts of the inner wall of the chassis 1 through a connecting structure; there are two lead screws 14, and the two lead screws 14 are symmetrically distributed at the bottom of the chassis 1, and the lead screws 14 are of equal length reverse thread structures.

By setting up the strong torsion spring 18, it can be ensured that the pin wire pressure plate 8 always applies pressure to the pin wire, and the pin wire pressure plate 8 can be ensured to rotate sideways synchronously through the rotating shaft inside the strong torsion spring 8.

[0033] Working principle: Use a narrow magnetized conveyor belt 9 to convey the placed electronic components to the range between the two pressing blocks 7. At the same time, most of the two pins of the electronic components are located between the pin pressure plate 8 and the pin push plate 11. At this time, the oil cylinder 13 is in an extended state, pushing the front end surface of the outer side of the pressing block 7 to press on the corresponding part of the root of the pin of the electronic component, and the pin pressure plate 8 presses the remaining part of the pin against the outer surface of the pin push plate 11.

[0034] The specific operations are as follows:

[0035] S1, two or more electronic components are placed on the magnetized conveyor belt 9 in sequence and at equal distances, and the magnetic field on the magnetized conveyor belt 9 and the pins of the electronic components with magnetic attraction materials are magnetically attracted to each other and fixed;

[0036] S2, by running the moving magnetized conveyor belt 9, the same group of electronic component pins can be placed at the station to be folded;

[0037] S3, operating the oil cylinder 2 4 in an extended or contracted state to adjust the U-shaped plate 1 2 and its connecting part up and down, so as to ensure that the front end surface of the pressing block 7 and the root of the electronic component lead wire to be pressed and fixed are kept at the same height;

[0038] S4, in synchronization with S3, the pin wire pressing plate 8 presses the remaining part of the pin wire of the electronic component onto the outer surface of the pin wire pushing plate 11;

[0039] S5, the oil cylinder 1 3 is in the extended state, pushing the outer front end surface of the pressing block 7 to press the corresponding part of the root of the electronic component lead wire, and the lead wire pressing plate 8 presses the remaining part of the lead wire against the outer surface of the lead wire pushing plate 11;

[0040] S6, by running the motor 15 to drive the lead screw 14 to rotate, the two pin wire pushing plates 11 connected by the internal threaded short tube 13 are moved outward and unfolded, and the pin wire part that can be reinforced between the pin wire pressing plate 8 and the pin wire pushing plate 11 is bent outward to complete the bending processing operation of the pin wire of the electronic component;

[0041] To sum up: the pin wire clamping plate 8 and the pin wire pushing plate 11 with matching lengths are used to clamp the pin wire and rotate it sideways, and the root part of the pin wire is fixed at the outer end of the pressing bar 7, which can complete the structural function of folding at least two limited numbers of electronic component pin wires, replace the mold folding structure, and can fold the electronic component pin wires at different inclination angles, solving the problem of the single folding state. At the same time, it has the function of conveying electronic components, thereby improving the folding processing efficiency of the electronic component pin wires.
