[0047] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0048] As Figures 1 to 5 shown, a terminal machine according to an embodiment of the present invention includes a frame 1, a moving mechanism 2, a clamping mechanism 3 and a crimping mechanism 4; the moving mechanism 2 is arranged on the frame 1, the moving mechanism 2 is connected to the clamping mechanism 3 and drives the clamping mechanism 3 to move between a first position and a second position. When in the first position, the clamping mechanism 3 clamps the terminal, and when in the second position, the crimping mechanism 4 crimps the terminal.

[0049] The clamping mechanism 3 includes a first clamping block 31 and a second clamping block 32. The first clamping block 31 and the second clamping block 32 can approach or move away from each other. A first clamping opening 33 is formed between one side surface of the first clamping block 31 and one side surface of the second clamping block 32, and a second clamping opening 34 is formed between the other side surface of the first clamping block 31 and the other side surface of the second clamping block 32. The first clamping opening 33 and the second clamping opening 34 can clamp various types of different terminals, so as to greatly improve the crimping flexibility.

[0050] The crimping mechanism 4 is arranged on the frame 1. After the moving mechanism 2 drives the clamping mechanism 3 to move to the second position, the crimping mechanism 4 drives the first clamping block 31 to tightly press the second clamping block 32.

[0051] When crimping a terminal, first place the terminal within the first clamping opening 33 and the second clamping opening 34, so that terminals of different sizes and models can be clamped. Then, the moving mechanism 2 drives the clamping mechanism 3 to move to the second position. A wire is inserted into the terminal, and the crimping mechanism 4 drives the first clamping block 31 to tightly press against the second clamping block 32 to achieve the crimping of the terminal. Therefore, both sides of the present invention can crimp terminals, improving the crimping efficiency. Moreover, there are multiple crimping openings of different sizes on both sides, so that different types of terminals can be crimped without changing the mold, improving the crimping flexibility.

[0052] Among them, multiple first clamping openings 33 of different sizes can be formed between one side surface of the first clamping block 31 and one side surface of the second clamping block 32, and multiple second clamping openings 34 of different sizes can be formed between the other side surface of the first clamping block 31 and the other side surface of the second clamping block 32. In this example, six first clamping openings 33 are provided, and six second clamping openings 34 are provided. In this way, twelve different types of terminals can be clamped, greatly improving the crimping flexibility.

[0053] After the clamping mechanism 3 clamps and fixes the terminal, the drive motor 21 drives the driving wheel 22 to rotate. The rotation of the driving wheel 22 drives the driven wheel 23 to rotate through the connecting belt, and the clamping mechanism 3 is connected to the connecting belt, thereby driving the clamping mechanism 3 to move to move to the second position to facilitate the crimping operation of the crimping mechanism 4.

[0054] Meanwhile, in order to enable the clamping mechanism 3 to move better on the frame 1, slide rails can be provided on the frame 1, and sliders are provided on the clamping mechanism 3. The sliders cooperate with the slide rails to enable the clamping mechanism 3 to move smoothly on the frame 1.

[0055] In order to enable the first clamping block 31 and the second clamping block 32 to approach or move away from each other, in some examples, the clamping mechanism 3 further includes a clamping cylinder 35. The clamping cylinder 35 is provided on the first clamping block 31, and the movable end of the clamping cylinder 35 is connected to the second clamping block 32. The clamping cylinder 35 drives the first clamping block 31 to approach or move away from the second clamping block 32.

[0056] Optionally, the terminal machine may further include a fixing mechanism 5. The fixing mechanism 5 is connected to the clamping mechanism 3, and the fixing mechanism 5 is used to clamp the sheet-like portion 62 of the terminal 6. In this example, the fixing mechanism 5 may include a first fixing member 51 and a second fixing member 52. The first fixing member 51 is provided on the first clamping block 31, the second fixing member 52 is provided on the second clamping block 32, and a clamping space for clamping the sheet-like portion 62 of the terminal 6 is formed between the second fixing member 52 and the first fixing member 51.

[0057] In this example, the terminal machine may further include a limiting component 53. The limiting component 53 includes a driving cylinder 531, a connecting block 532, a first limiting rod 533, a second limiting rod 534, and a limiting frame 535. The driving cylinder 531 is arranged on the frame body 1. The connecting block 532 is connected to the movable end of the driving cylinder 521 and is driven by the driving cylinder 531 to move. One end of the first limiting rod 533 is arranged on one side of the connecting block 532, and one end of the second limiting rod 534 is arranged on the other side of the connecting block 532. The limiting frame 535 is connected to the clamping cylinder 35 and is driven by the clamping cylinder 35 to move. The limiting frame 535 abuts against the first limiting rod 533 and the second limiting rod 534 for limiting.

[0058] When the second fixing member 52 needs to approach the first fixing member 51 to clamp the sheet-like portion 62 of the terminal 6, the clamping cylinder 35 drives the second fixing member 52 to approach the first fixing member 51 for clamping. At the same time, the clamping cylinder 35 drives the limiting frame 535 to descend. And the driving cylinder 531 drives the connecting block 532, the first limiting rod 533, and the second limiting rod 534 to move, that is, drives the first limiting rod 533 and the second limiting rod 534 to rise to abut against the limiting frame 535, thereby restricting the descent of the limiting frame 535.

[0059] Figure 6 It is a schematic structural diagram of an OT terminal, Figure 7 It is a schematic structural diagram of a UT terminal, as Figure 6 and Figure 7 shown. Usually, some terminals 6 such as OT terminals or UT terminals include a body portion 61 and a sheet-like portion 62. When clamping and fixing an OT terminal or a UT terminal, it is necessary to first fix the sheet-like portion 62 of the OT terminal or the UT terminal, and then fix the body portion 61 to make the clamping more firm. In this example, before clamping the body portion 61, the sheet-like portion 62 of the OT terminal or the UT terminal can be clamped and placed in the clamping space formed between the second fixing member 52 and the first fixing member 51. Then, the clamping cylinder 35 can drive the second fixing member 52 to approach the first fixing member 51 to effectively fix the sheet-like portion 62 of the terminal 6, and then fix the body portion 61 to improve the stability when fixing the terminal.

[0060] In some examples, the moving mechanism 2 includes a driving motor 21, a driving wheel 22, a driven wheel 23, and a connecting belt (not shown in the figure). The driving motor 21 is fixed on the frame body 1. The driving wheel 22 is arranged on the movable end of the driving motor 21 and is driven by the driving motor 21 to rotate. The driven wheel 23 is arranged on the frame body 1. The connecting belt connects the driving wheel 22 and the driven wheel 23, and the clamping mechanism 3 is connected to the connecting belt.

[0061] To improve the crimping effect when the terminal is crimped with the wire, a support block 11 can be formed to protrude on the frame body 1. The moving mechanism 2 drives the second clamping block 32 of the clamping mechanism 3 to move onto the support block 11. In this way, when the first clamping block 31 squeezes the second clamping block 32, the second clamping block 32 is placed on the support block 11, and the support block 11 can effectively provide a supporting effect, making the crimping process more stable.

[0062] Among them, in order to enable the clamping mechanism 3 to move onto the support block 11 more smoothly, an inclined surface and a support surface are provided on the support block 11, and the bottom of the second clamping block 32 moves from the inclined surface to the support surface.

[0063] As an example, the crimping mechanism 4 includes a crimping motor 41, a rotating shaft 42, an eccentric wheel 43, a connecting member 44, and a crimping block 45. The crimping motor 41 is arranged on the frame body 1. One end of the rotating shaft 42 is connected to the crimping motor 41 and is driven by the crimping motor 41 to rotate. The eccentric wheel 43 is connected to the other end of the rotating shaft 42 and is driven by the rotating shaft 42 to rotate. A groove 441 is formed in the connecting member 44, and the eccentric wheel 43 is placed in the groove 441 to drive the connecting member 44 to move. The crimping block 45 is arranged on one side of the connecting member 44. When the connecting member 44 moves, it drives the crimping block 45 to move, and when the crimping block 45 moves, it squeezes the first clamping block 31.

[0064] Through the setting of the eccentric wheel 43, the eccentric wheel 43 is placed in the groove 441. When the eccentric wheel 43 rotates, it drives the connecting member 44 to move up and down. When the connecting member 44 moves downward, it squeezes the first clamping block 31 to change the sizes of the first clamping opening 33 and the second clamping opening 34, so as to effectively crimp the terminal and the wire.

[0065] In order to appropriately adjust the height of the crimping block 45 to facilitate better crimping of the terminal and the wire, in this example, the crimping mechanism 4 further includes an adjusting knob 46. The adjusting knob 46 is connected to the crimping block 45 and adjusts the height of the crimping block 45. Manually rotating the adjusting knob 46 can adjust the height of the crimping block 45. In order to reset the adjusting knob 46, an adjusting spring can be arranged in the crimping block 45, and the adjusting spring is compressed to facilitate the reset of the adjusting knob 46.

[0066] In order to enable the crimping motor 41 to better control the rotation of the rotating shaft 42, a speed reducer 47 can be arranged between the crimping motor 41 and the rotating shaft 42 to precisely control the rotation of the rotating shaft 42 and control the movement of the crimping block 45.
