[0027] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0028] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The utility model provides a terminal crimping machine, which includes a table 1, a pressing mechanism 2, a driving mechanism 3, a moving mechanism 4, a clamping mechanism 5, an industrial camera 6 and a controller. The pressing mechanism 2 is arranged on the table 1; the driving mechanism 3 is arranged on the table 1 and is located on one side of the pressing mechanism 2. The moving mechanism 4 is connected to the driving mechanism 3 and can approach or move away from the pressing mechanism 2 under the drive of the driving mechanism 3. The clamping mechanism 5 is arranged on the moving mechanism 4. The industrial camera 6 is arranged on the table 1, and its shooting end faces the pressing area of ​​the pressing mechanism 2. The controller is electrically connected to the pressing mechanism 2, the driving mechanism 3, the moving mechanism 4 and the industrial camera 6.

[0029] In a specific application, the clamping mechanism 5 clamps the wire to be terminald, and the end of the wire to be terminald is exposed from the clamping mechanism 5. The driving mechanism 3 can drive the moving mechanism 4 to approach or move away from the pressing mechanism 2, thereby driving the clamping mechanism 5 to approach or move away from the pressing mechanism 2. When the clamping mechanism 5 drives the end of the wire to move to the pressing area, the industrial camera 6 obtains the image of the pressing area and feeds it back to the controller. If the end of the wire is in a predetermined position, the controller controls the pressing mechanism 2 to press the terminal on the end of the wire. If the end of the wire is not in a predetermined position, the controller controls the driving mechanism 3 to drive the moving mechanism 4 and the clamping mechanism 5 to move until the end of the wire is in a predetermined position and then controls the pressing mechanism 2 to press the terminal on the end of the wire to ensure the accuracy of the pressing.

[0030] Specifically, the drive mechanism 3 comprises a drive motor 31, a ball screw 32, and a ball nut 33. The drive motor 31 is mounted on the table 1. The ball screw 32 is rotatably mounted on the table 1, with one end connected to the output shaft of the drive motor 31. The ball nut 33 is sleeved on the ball screw 32 and connected to the moving mechanism 4.

[0031] Specifically, the above-mentioned moving mechanism 4 includes two guide rails 41, two groups of sliders 42 and a moving plate 43; the two guide rails 41 are laid parallel to the table 1 and are parallel to the ball screw 32; the two groups of sliders 42 are respectively slidably set on the two guide rails 41; the moving plate 43 connects the two groups of sliders 42 and is connected to the ball nut 33.

[0032] In a specific application, the driving motor 31 generates a driving force to drive the ball screw 32 to rotate, and the ball screw 32 drives the ball nut 33 to move, thereby driving the movable plate 43 and the slider 42 to move along the length direction of the guide rail 41, so as to drive the wire clamped by the clamping mechanism 5 to move.

[0033] In some preferred embodiments, the drive mechanism 3 further includes two synchronous pulleys 34 and a synchronous belt. The two synchronous pulleys 34 are respectively mounted on the ball screw 32 and the output shaft of the drive motor 31. The synchronous belt is wound around the two synchronous pulleys 34. Connecting the drive motor 31 and the ball screw via the synchronous belt and synchronous pulleys 34 provides higher transmission efficiency, more accurate transmission ratios, lower noise, and lower maintenance costs compared to a direct connection between the drive motor 31 and the ball screw.

[0034] Specifically, the above-mentioned clamping mechanism 5 includes a fixed seat 51, a lower clamping die 52, a support rod 53, a mounting plate 54, a clamping drive cylinder 55 and an upper clamping die 56.

The clamping drive cylinder 55 is arranged on the mounting plate 54, and its output end faces the lower clamping die 52. The upper clamping die 56 is connected to the output end of the clamping drive cylinder 55, and the upper clamping die 56 can be driven by the clamping drive cylinder 55 to move closer to or away from the lower clamping die 52. In specific applications, the clamping drive cylinder 55 drives the upper clamping die 56 to move toward the lower clamping die 52, so that the upper clamping die 56 cooperates with the lower clamping die 52 to clamp the wires.

[0035] In some preferred embodiments, the lower clamping die 52 and the upper clamping die 56 are provided with grooves 521 that are adapted to the shape of the wire on the opposite side. This technical solution can not only increase the clamping force, but also protect the surface of the wire.

[0036] In some preferred embodiments, the lower clamping die 52 and the upper clamping die 56 are provided with an extension portion 522 extending toward the pressing mechanism 2 on one side thereof close to the pressing mechanism 2. This technical solution not only provides better support for the wires, but also prevents interference between the clamping mechanism 5 and the pressing mechanism 2.

[0037] In some preferred embodiments, the above-mentioned pressing mechanism 2 includes a bracket 21, a lower mold 22, a pressing drive cylinder 23 and an upper mold 24. The bracket 21 is arranged on the table 1 and is located on one side of the driving mechanism 3.

[0038] In some preferred embodiments, the terminal punching machine further comprises a feeding mechanism 7, which is arranged on the bracket 21. The feeding mechanism 7 is used to transfer the multiple terminals connected together one by one to the corresponding lower die 22. Specifically, the feeding mechanism 7 comprises a fixed block 71, a moving block 72, a spring 73, a fixed plate 74, a rotating plate 75, a connecting block 76, a feeding rod 77 and a tension spring 78. The fixed block 71 is arranged on the bracket 21, and the lower die 22 is arranged on the fixed block 71. The moving block 72 passes through the fixed block 71 and is located on one side of the lower die 22. The top of the moving block 72 is provided with a placement groove 721, and the side of the moving block 72 close to the lower die 22 is provided with a feeding opening 722. The spring 73 is arranged in the fixed block 71, one end of which abuts the bracket 21, and the other end abuts the moving block 72. The fixed plate 74 is arranged on the bracket 21. One end of a rotating plate 75 is rotatably mounted on a fixed plate 74. A guide groove 751 is provided on the rotating plate 75.

A loading rod 77 is rotatably mounted on the connecting block 76. One end of a tension spring 78 is connected to the rotating plate 75, and the other end of the tension spring 78 is connected to the loading rod 77.

[0039] In a specific application, one end of the multiple terminals connected together passes through the feeding opening 722. When the pressing drive cylinder 23 drives the upper mold 24 to press down, the lower pressing block 79 and the rolling wheel 710 move downward at the same time. The lower pressing block 79 pushes the moving block 72 to move downward. During the downward movement of the moving block 72, it cooperates with the lower mold 22 to cut off one of the multiple terminals connected together, and the terminal is pressed at a predetermined position at the end of the wire under the action of the upper mold 24 and the lower mold 22. When the rolling wheel 710 moves downward, it cooperates with the guide groove 751 to rotate the rotating plate 75, and the rotating plate 75 drives The connecting block 76 and the loading rod 77 rotate. At the same time, the loading rod 77 also rotates a certain angle under the action of the tension spring 78. After the pressing is completed, the pressing drive cylinder 23 drives the upper mold 24 to move upward, and the lower pressing block 79 and the rolling wheel 710 move upward at the same time. The moving block 72 is reset under the action of the spring 73, and the rotating plate 75 is reset under the action of the rolling wheel 710 and the guide groove 751. The loading rod 77 is also reset. During the resetting process of the loading rod 77, the end thereof close to the moving block 72 will push the multiple terminals connected together forward by the distance of one terminal in the direction of the moving block 72, thereby realizing automatic loading.
