[0002] The electronic connector includes a product housing and a pin body. The pin insertion process of traditional electronic connectors is usually manually operated.

[0003] There is a pin insertion machine on the market that includes a frame, a feed tray frame, a cutting device, and a pin pressing mechanism. A tray of pins is provided on the feed tray frame, which is pulled to the cutting device by a worker for transportation and cutting. Then, the cut pins are pressed into the terminals by the pin pressing mechanism to form products. However, the pin insertion machine only straightens the pins by a pulling roller when cutting them, so that the curvature of the pins themselves still exists, which leads to a high defective rate of the products formed after the pins are processed.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a pin insertion machine with a straightening function. By arranging a driving sleeve that drives the mounting plates on the two straightening groups to move closer to or away from each other, the straightening mechanism can adapt to pins of different sizes and at the same time make the center lines of the two straightening groups collinear.

[0017] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] A pin insertion machine with a straightening function, such as Figures 1 to 4 As shown, it includes a machine body 1, and a loading tray 2 and a pin assembly 3 arranged on the machine body 1. The machine body 1 is also provided with a straightening mechanism 4, and the straightening mechanism 4 is established between the loading tray 2 and the pin assembly 3.

[0019] refer to Figure 2 , Figure 3 and Figure 4As shown: the straightening mechanism 4 includes a mounting sleeve 5, a driving sleeve 8, and two straightening groups arranged perpendicular to each other, each of the two straightening groups includes two fixed rods 6, and a plurality of straightening stress-relieving wheels 7 in a toothed shape that are rotatably arranged on the two fixed rods 6, and the straightening stress-relieving wheels 7 on the two fixed rods 6 are staggered with each other, the mounting sleeve 5 has four sliding grooves in a circular array centered on the axis, the four fixed rods 6 are slidably arranged in the sliding grooves, the driving sleeve 8 is rotatably sleeved on the mounting sleeve 5, the inner wall of the driving sleeve 8 has four arc grooves in a circular array corresponding to the four fixed rods 6, and the fixed rods 6 are provided with limit plates 9 corresponding to the arc grooves, and the limit is in contact with the arc groove.

[0020] When the equipment straightens pins of different sizes, the pins pass through the straightening mechanism 4 and then enter the pin assembly 3. When the diameters of the pins are different, the driving sleeve 8 is rotated so that the arc groove on the driving sleeve 8 squeezes the limit plate 9 to slide in the sliding groove, thereby achieving the purpose of adjusting the two straightenings at the same time, so that the fixing rods 6 on the two straightening groups slide along the radial direction of the driving sleeve 8, so that the center lines of the two straightening groups are in line, thereby preventing the pins from being completely dislocated again due to the non-collinearity of the straightening groups in two directions.

[0021] refer to Figure 3 and Figure 4 As shown: the four fixing rods 6 are all integrally formed with a limiting platform 10, the mounting sleeve 5 is connected to a plurality of elastic members 11 in a ring array by bolts, and the plurality of elastic members 11 are respectively fixedly connected to the limiting platforms 10 on the four fixing rods 6 by bolts, and the elastic members 11 have elastic potential energy for pushing the fixing rod 6 to slide toward the driving sleeve 8.

[0022] When the fixing rod 6 is adjusted, the elastic member 11 can cause the fixing rod 6 to slide toward the driving sleeve 8 , so that the fixing rod 6 is reset to the maximum straightening diameter.

[0023] refer to Figure 4 As shown: support plates 12 are integrally formed on both ends of the mounting sleeve 5, a through hole 13 is opened on the support plate 12, a limiting rod 14 is inserted in the through hole 13, the driving sleeve 8 has a plurality of limiting holes 15 in a circular array corresponding to the through hole 13, a rotating handle is integrally formed on the driving sleeve 8, and the limiting rod 14 passes through the through hole 13 and is inserted in the limiting hole 15.

[0024] The driving sleeve 8 is rotated by turning the handle to rotate the driving sleeve 8. After the required size is adjusted, the driving sleeve 8 is fixed by inserting and pulling out the limit rod 14, thereby achieving the distance between the fixing rod 6 and the straightening and stress relief wheel 7.

[0025] Working principle:

[0026] By turning the handle to rotate the driving sleeve 8, the arc-shaped groove on the driving sleeve 8 squeezes the limit plate 9, so that the fixed rod 6 slides in the sliding groove, and the elastic member 11 can push the fixed rod 6 to slide toward the driving sleeve 8, thereby achieving the effect of adjusting the fixed rod 6. The staff rotates the driving sleeve 8 according to the size of the required straightening pin until the gap between the straightening stress relief wheels 7 corresponds to the size of the pin, and then inserts the pin in the through hole 13 into the limit hole 15, thereby achieving the effect of fixing the driving sleeve 8, so that the straightening mechanism 4 can adapt to pins of different sizes, and at the same time can make the center lines of the two straightening groups collinear.
