[0037] Reference Figure 1The terminal crimping die comprises a base 100, a stamping mechanism 300, a feeding track 900, a positioning mechanism 500 and a wire guide mechanism 600. The base 100 is provided with a processing position 150. The stamping mechanism 300 is arranged on the base 100 and can perform stamping processing on the terminal in the processing position 150. The feeding track 900 extends to the processing position 150. A material pushing mechanism 200 is arranged beside the feeding track 900. The material pushing mechanism 200 can push a single terminal to move to the processing position 150. The positioning mechanism 500 is arranged on the base 100 and can position and fix the terminal in the processing position 150 and the base 100. The wire guide mechanism 600 is arranged on the base 100 and is used to guide the wire to move to the processing position 150 and position the wire and the processing position 150. The terminal on the feeding track 900 can enter the processing position 150 one by one under the action of the material pushing mechanism 200. When the terminal is transported to the processing position 150, the positioning mechanism 500 can position the terminal, and the wire guide mechanism 600 can also position the wire. Thus, the terminal and the wire can be positioned in the processing position 150, so that the stamping mechanism 300 can accurately crimp and form the terminal and the wire. Since the terminal and the wire have completed the relative positioning with the processing position 150 when being transported to the processing position 150, it is not necessary to use a visual detection device to detect the position, thereby effectively saving the cost and improving the processing cost. Since the positioning is completed during the transportation, it is not necessary to additionally position the terminal, thereby effectively improving the work efficiency.

[0038] In some embodiments, with reference to Figure 2 The material pushing mechanism 200 comprises a material pushing cylinder 210 arranged on the base 100 and connected with a first pushing fork 220. The feeding track 900 can drive the terminal to move towards the processing position 150. The first pushing fork 220 can move into the feeding track 900 and stop the terminal on the feeding track 900 from continuously moving. The feeding track 900 transports the terminals. When the material pushing cylinder 210 is started, the first pushing fork 220 can move into the feeding track 900 and between the terminals, so that the first pushing fork 220 can stop the terminal before it and the terminal after it can continuously move. Thus, the first pushing fork 220 can repeatedly stop the single terminal, so that the movement speed of the terminals on the feeding track 900 is different, and the terminals can enter the processing position 150 one by one, so that the processing position 150 can successfully perform the crimping work on the terminals.

[0039] Specifically, the feeding track 900 is provided with a position sensor, when the first fork 220 extends into the feeding track 900, the position sensor can detect the position of the first fork 220, so as to ensure that when the first fork 220 extends into or leaves the feeding track 900, a single terminal will be continuously driven by the feeding track 900 and moved to the processing position 150.

[0040] Further, the bottom of the feeding track 900 has a plurality of feeding rollers, and the rotation of the rollers realizes the effect of driving the terminals to feed.

[0041] In some embodiments, referring to Figure 2 , the material stirring cylinder 210 is connected with a second fork 230, the material stirring cylinder 210 can drive the first fork 220 and the second fork 230 to move reversely, the second fork 230 can move into the feeding track 900 and stop the terminal on the feeding track 900 from continuing to move; the first fork 220 has a first end 225 for extending into the feeding track 900, the second fork 230 has a second end 235 for extending into the feeding track 900, and the first end 225 and the second end 235 have a gap suitable for a single terminal. When the first fork 220 extends into the feeding track 900 and blocks the terminal in front of the first track, since the moving direction of the second fork 230 and the first fork 220 is opposite, the second fork 230 will leave the feeding track 900, and the terminal between the first fork 220 and the second fork 230 can continue to move towards the processing position 150. Since the gap between the first end 225 and the second end 235 is suitable for a single terminal, the terminal between the first fork 220 and the second fork 230 is only one, when the first fork 220 and the second fork 230 alternately extend into the feeding track 900, the single terminal can continue to move towards the processing position 150, so as to directly and effectively achieve the purpose of sending the single terminal to the processing position 150, and provide convenience for subsequent processing.

[0042] In some embodiments, referring to Figure 4 , the stamping mechanism 300 includes a stamping driving device 310 installed above the processing position 150, the stamping driving device 310 is connected with a stamping die head 350 and can drive the stamping die head 350 to descend close to the processing position 150 or rise away from the processing position 150. After the stamping driving device 310 is started, the stamping die head 350 can be driven to descend and perform stamping work on the terminal at the processing position 150, so that the terminal at the processing position 150 and the wire can be directly and effectively crimped, and then the processing and forming work between the terminal and the wire can be smoothly completed.

[0043] Specifically, the stamping driving device 310 is connected with the in-place sensor 370, so that the positional relationship between the stamping die head 350 and the processing position 150 can be detected, and the stamping die head 350 can accurately perform the crimping work on the terminal on the processing position 150.

[0044] It can be envisaged that the stamping driving device 310 can be a hydraulic cylinder, an air cylinder, or a combination of a motor and a screw rod, etc. The specific embodiments can be adjusted according to actual needs, which are not limited here.

[0045] In some embodiments, referring to Figure 3 , the base 100 is provided with the lifting mechanism 400, the stamping mechanism 300 is located above the processing position 150 and performs stamping on the terminal on the processing position 150; the lifting mechanism 400 is located below the processing position 150 and can lift the terminal relative to the processing position 150. After the crimping work of the terminal and the wire is completed, the lifting mechanism 400 can lift the terminal from the processing position 150, so that the processed terminal and the processing position 150 are separated from each other, and then the processed terminal can be smoothly taken away, so as to facilitate the subsequent terminal to enter the processing position 150 and perform the crimping work.

[0046] In some embodiments, referring to Figure 7 , the lifting mechanism 400 includes a lifting cylinder 410 and a lifting lever 420, the lifting lever 420 can be flipped relative to the base 100; the lifting cylinder 410 is connected to one end of the lifting lever 420, and the other end of the lifting lever 420 extends below the processing position 150. After the lifting cylinder 410 is started, it can drive the lifting lever 420 to flip relative to the base 100. When the lifting cylinder flips, the end thereof located below the processing position 150 will be lifted to the processing position 150, and in the subsequent process of continuing to flip, the terminal will be lifted, so that the lifting work of the processed terminal can be directly and effectively completed.

[0047] It can be envisaged that the lifting lever 420 can extend below the processing position 150 from the left and right sides of the processing position 150, or can extend below the processing position 150 from the front and rear sides of the processing position 150. The specific embodiments can be adjusted according to actual needs, which are not limited here.

[0048] In some embodiments, referring to Figure 8The positioning mechanism 500 comprises a positioning cylinder 510 and a pushing rod 520. The positioning cylinder 510 is connected with the pushing rod 520 and can drive the pushing rod 520 to move relative to the base 100. The processing position 150 is provided with a positioning seat 530. The pushing rod 520 can push the terminal to the positioning seat 530 and make the terminal positioned at the processing position 150. When the terminal is conveyed to the processing position 150, the terminal will be between the pushing rod 520 and the positioning seat 530. When the pushing rod 520 is driven by the positioning cylinder 510, the pushing rod 520 will move close to the positioning seat 530 and cooperate with the positioning seat 530 to realize the clamping effect of the terminal. Therefore, the positioning and fixing of the terminal can be effectively achieved, and the crimping operation can be smoothly and accurately performed.

[0049] In some embodiments, with reference to 8, when the terminal to be processed is a terminal with an angle, the pushing rod 520 can push the bent part of the terminal to the positioning seat 530. The specific implementation can be adjusted according to actual needs, which is not limited here.

[0050] In some embodiments, with reference to Figure 4 The base 100 is movably provided with a displacement seat 120. The processing position 150 and the pushing rod 520 are located in the displacement seat 120. The displacement seat 120 can linearly slide relative to the base 100. The sliding direction of the displacement seat 120 and the movement direction of the pushing rod 520 are staggered with each other. When the pushing rod 520 pushes the terminal to the positioning seat 530, the terminal will be positioned relative to the displacement seat 120 in the movement direction of the pushing rod 520. When the displacement seat 120 linearly slides, it can drive the terminal to adjust and position in another direction. Therefore, the terminal can be effectively positioned in multiple directions, and the terminal can be accurately positioned relative to the stamping mechanism 300.

[0051] Specifically, the base 100 is provided with a screw nut pair 125, and the screw nut pair 125 is connected with a handle. The screw nut pair 125 can be driven to rotate by the handle, so as to drive the displacement seat 120 to adjust the displacement, and then the terminal can be positioned smoothly.

[0052] Further, the displacement seat 120 is provided with a detection sensor 430. The detection sensor 430 can detect whether the terminal and the processing position 150 are in place, so as to ensure that the crimping operation can be smoothly performed.

[0053] In some embodiments, with reference to Figure 6The wire guide mechanism 600 comprises a wire guide cylinder 610 connected with two wire guide levers 620 and capable of driving the two wire guide levers 620 to relatively approach or move away from each other; the wire guide lever 620 has a wire guide part 630, and when the two wire guide levers 620 relatively approach and converge with each other, the two wire guide parts 630 can form a wire guide hole 635, and the end of the wire guide hole 635 is located at the processing position 150. When the wire is transported towards the processing position 150, the wire guide cylinder 610 can drive the two wire guide levers 620 to move close to the wire. When the two wire guide levers 620 converge, the two wire guide parts 630 will form the wire guide hole 635, and the wire guide hole 635 and the processing position 150 are connected, so that the position of the wire can be gradually guided to the processing position 150 through the wire guide hole 635, and the effect of guiding and positioning the wire can be achieved smoothly.

[0054] In some embodiments, with reference to Figure 5 The wire guide hole 635 is a horn hole. The horn hole has a curved inner wall gradually towards the center, so that the wire can be positioned and guided to the center of the wire guide hole 635 through the curved inner wall, and the wire can be smoothly and accurately extended to the processing position 150, and the subsequent crimping operation can be accurately performed.

[0055] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0056] The embodiments of the application are described in detail above in combination with the drawings, but the application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the application.
