DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-8 The present invention provides a technical solution: an electronic component precision manufacturing device, comprising a pin insertion machine body 1, the pin insertion machine body 1 comprising a base 11, one end of the base 11 is slidably connected with a pin insertion hole 12, and the pin insertion hole 12 is loaded with a pin 13;

[0029] A cutting mechanism 2, the cutting mechanism 2 is located above the pin 13, and the cutting mechanism 2 can cut off the plastic shell attached to the periphery of the pin 13;

[0030] An energy storage mechanism 3, the energy storage mechanism 3 is located between the pin insertion hole 12 and the cutting mechanism 2, and the energy storage mechanism 3 can store energy for the cutting mechanism 2 when the pin insertion hole 12 pushes the pin 13;

[0031] When the present invention is in use, when the pin hole 12 pushes the pin 13, the energy storage mechanism 3 can store energy for the cutting mechanism 2. When the cutting piece 5 rotates to the periphery of the pin 13, continuing to push the pin hole 12 can trigger the cut-off piece 7, release the kinetic energy stored in the energy storage mechanism 3, cut off the plastic around the pin 13, expose the pin 13, and facilitate welding or fixing the pin 13. It is very convenient to use.

[0032] The cutting mechanism 2 includes a sliding box 21 fixedly connected to the outer wall of the base 11, a sliding plate 22 is slidably connected inside the sliding box 21, the bottom of the sliding plate 22 is fixedly connected to the pin hole 12 via a connecting block 23, a plurality of teeth 24 are fixedly connected to the bottom of the sliding plate 22, a fixing rod 25 is fixedly connected to the inner wall of the sliding box 21, a transmission gear 26 is rotatably connected to the outer periphery of the fixing rod 25, the teeth 24 mesh with the transmission gear 26, and a cutting box 27 is fixedly connected to the outer wall of the transmission gear 26;

[0033] When the connector is inserted, the pin hole 12 located inside the base 11 first heats the pin 13. After the pin 13 is heated, when the pin 13 is pushed through the pin hole 12, the heated pin 13 penetrates the plastic shell of the connection box and melts the plastic shell. The melted plastic shell stretches and adheres to the periphery of the pin 13. When the pin hole 12 slides, the sliding plate 22 is driven to slide inside the sliding box 21 through the connecting block 23. Since a limiting member 4 for limiting the sliding plate 22 is provided inside the sliding box 21, the limiting member 4 includes a limiting block 41 fixedly connected to the inner wall of the sliding box 21, and a limiting groove 42 is provided above the sliding plate 22. The limiting block 41 is located inside the limiting groove 42 and The limit block 41 is slidably connected to the limit groove 42 and is wedge-shaped. When the sliding plate 22 slides, the limit block 41 located on the inner wall of the sliding box 21 slides in the limit groove 42 opened on the sliding plate 22. When the sliding plate 22 slides, the teeth 24 located at the bottom of the sliding plate 22 mesh with the transmission gear 26 and drive the transmission gear 26 to rotate around the fixed rod 25. The transmission gear 26 drives the cutting box 27 located under the sliding box 21 to rotate until the cutting box 27 rotates to the periphery of the pin 13 that has penetrated the plastic shell. A cutting piece 5 for cutting off excess plastic is provided inside the cutting box 27. The cutting piece 5 can cut off the plastic shell around the pin 13 to facilitate exposure of the pin 13.

[0034] The cutting piece 5 includes a through slot 51 provided at the center of the cutting box 27, a cutting slot 52 provided inside the cutting box 27, an arc rod 53 fixedly connected to the inner wall of the cutting slot 52, a conveying belt 54 slidably connected to the outer periphery of the arc rod 53, a plurality of supporting blocks 55 fixedly connected to one end of the conveying belt 54 close to the through slot 51, a cutting knife 56 fixedly connected to one end of each supporting block 55 away from the conveying belt 54, a plurality of windshield plates 57 fixedly connected to the outer wall of the conveying belt 54, the windshield plates 57 are located at one end of the conveying belt 54 away from the cutting knife 56, and the windshield plates 57 are located inside the cutting slot 52 and slidably connected to the cutting slot 52;

[0035] When the cutting box 27 rotates to the periphery of the pin 13, the pin 13 is located inside the through groove 51 opened in the cutting box 27, and the conveyor belt 54 located inside the cutting groove 52 opened in the cutting box 27 slides around the arc rod 53 through the energy storage mechanism 3. The cutter 56 fixedly connected to the inner side of the conveyor belt 54 is located outside the pin 13 and rotates. Since the cutting groove 52 is annular, the conveyor belt 54 can drive the cutter 56 to slide along the cutting groove 52 when it slides. At this time, the cutter 56 can cut off the plastic shell attached to the periphery of the pin 13. Since the plastic shell is still connected to the connector shell after high-temperature stretching, after the cutter 56 cuts off the excess plastic shell, the plastic shell located outside the pin 13 naturally falls off, which is convenient for the next step of welding and other operations on the pin 13.

[0036] The energy storage mechanism 3 includes a piston cylinder 31 fixedly connected to the outer wall of the pin hole 12, a piston plate 32 is slidably connected inside the piston cylinder 31, a push rod 33 is fixedly connected to one end of the piston plate 32 away from the inner wall of the piston cylinder 31, the push rod 33 is located above the pin 13 and is slidably connected to the pin 13, an energy storage member 6 capable of driving the cutting box 27 is provided above the piston cylinder 31, the energy storage member 6 includes an air outlet 61 opened above the piston cylinder 31, an air inlet 62 is opened at the bottom of the cutting box 27, the air inlet 62 is connected to the cutting groove 52, an air bag 63 is fixedly connected to the outer wall of the piston cylinder 31, the air bag 63 is located outside the air outlet 61, and the other end of the air bag 63 is located outside the air inlet 62 and is fixedly connected to the outer wall of the cutting box 27;

[0037] When the connector is inserted, the pin hole 12 drives the pin 13 to be inserted into the plastic shell. When the pin hole 12 moves, the push rod 33 located above the pin 13 abuts against the connector plastic shell. When the pin insertion operation continues, the pin 13 is continuously inserted. At this time, the push rod 33 drives the piston plate 32 to squeeze the internal gas of the piston cylinder 31. The gas located inside the piston cylinder 31 enters the air bag 63 through the air outlet 61. At this time, the internal air pressure of the air bag 63 increases and stores the gas. When the internal gas of the air bag 63 is released, it can enter the inside of the cutting groove 52 through the air inlet 62. The gas drives the windshield 57 from the inside to be cut. The windshield 57 drives the conveyor belt 54 to slide around the arc rod 53. The excess gas is discharged through the exhaust hole 58, which is convenient for driving the cutting piece 5 to cut the plastic shell.

[0038] A cut-off piece 7 capable of cutting off the transmission of gas inside the airbag 63 is arranged on the periphery of the airbag 63. The cut-off piece 7 comprises a cut-off rod 71 fixedly connected to the inner wall of the sliding box 21, a torsion spring 72 fixedly connected to the outer wall of the cut-off rod 71, a rotating plate 73 fixedly connected to the end of the torsion spring 72 away from the cut-off rod 71, a cut-off plate 74 fixedly connected to the inner wall of the sliding box 21, the airbag 63 is located between the cut-off plate 74 and the rotating plate 73, the rotating plate 73 squeezes the airbag 63 and moves closer to the cut-off plate 74, a trigger rod 75 fixedly connected to the outer wall of the piston plate 32, the trigger rod 75 is L-shaped, the upper part of the trigger rod 75 is located below the cut-off plate 74, and the upper part of the trigger rod 75 is horizontally aligned with the rotating plate 73;

[0039] After the pin hole 12 drives the pin 13 to be inserted into the plastic shell, the pin hole 12 continues to be pushed, and the pin hole 12 drives the piston cylinder 31 to move. When the pushing rod 33 abuts the connector plastic shell, the pushing rod 33 squeezes the internal gas of the piston cylinder 31 through the piston plate 32, and squeezes the gas into the air bag 63 through the air outlet hole 61. At this time, the rotating plate 73 is driven by the torsion spring 72 to rotate and squeeze the air bag 63 and move closer to the cut-off plate 74. The gas inside the air bag 63 cannot enter the cutting groove 52. Continue to push the pin hole 12 until the pin 13 is inserted into the specified position. The trigger rod 75 located on the outer wall of the piston plate 32 pushes the rotating plate 73 to rotate around the cut-off rod 71. At this time, the rotating plate 73 is away from the cut-off plate 74, the air bag 63 is no longer squeezed, and enters the cutting groove 52 through the air inlet hole 62 and drives the cutting piece 5 to cut off the excess plastic shell, which is very convenient to use.
