[0030] 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:

[0031] like Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, the present invention provides a terminal crimping machine, comprising a workbench 1, two processing devices 2, and a crimping device 3. The two processing devices 2 are arranged in parallel on the workbench 1, and each processing device 2 includes a wire feeding mechanism 21, a wire moving mechanism 22, a wire cutting and stripping mechanism 23, a terminal crimping mechanism 24, and a transfer mechanism 25. The wire moving mechanism 22 is arranged on the side of the wire outlet end of the wire feeding mechanism 21, and the wire moving mechanism 22 has a first working state and a second working state. The wire cutting and stripping mechanism 23 is arranged on the side of the wire outlet end of the wire moving mechanism 22.

The terminal crimping mechanism 24 is arranged on the side of the wire cutting and stripping mechanism 23. When the wire moving mechanism 22 is in the second working state, the terminal crimping mechanism 24 corresponds to the wire moving mechanism 22. The transfer mechanism 25 is arranged on the side of the wire outlet end of the wire cutting and stripping mechanism 23.

[0032] In a specific application, both the pressing device 3 and the terminal crimping mechanism 24 adopt the terminal crimping machine in the prior art.

[0033] In specific applications, the wire feeding mechanism 21 includes two wire feeding wheels 211, a wire feeding drive motor, and a plurality of straightening wheels 212. The two wire feeding wheels 211 are arranged opposite each other, forming a space between them for the wire bundle to pass through. The wire feeding drive motor is connected to the two wire feeding wheels 211 via a connector to drive the two wire feeding wheels 211 to rotate toward each other. The plurality of straightening wheels 212 are divided into two groups, upper and lower, and the two groups of straightening wheels 212 are sequentially arranged on the side of the wire feeding end of the two wire feeding wheels 211.

[0034] In a specific application, the above-mentioned line-moving mechanism 22 includes a turntable 221, a rotation drive motor 222, a line-moving linear guide 223, a movable plate 224, a ball screw 225, a ball nut 226, a movable drive motor 227 and two line-moving clamping members 228. The turntable 221 is connected to the output end of the rotation drive motor 222 and can rotate forward or reverse under the drive of the rotation drive motor 222. The line-moving linear guide 223 is laid on the turntable 221. The movable plate 224 is connected to the slider of the line-moving linear guide 223. The ball screw 225 is rotatably set on the turntable 221 and is parallel to the line-moving linear guide 223. The ball nut 226 is sleeved on the ball screw 225 and connected to the movable plate 224. The movable drive motor 227 is set on the turntable 221, and its output end is connected to one end of the ball screw 225. The two line-moving clamping members 228 are relatively set on the movable plate 224. Specifically, the two wire-moving clamping members 228 are two cylinders, and the output ends of the two cylinders are connected to clamping plates, which have clamping grooves that are adapted to the shape of the wire harness.

[0035] In a specific application, the above-mentioned cutting and stripping mechanism 23 includes a fixed base 231, a bracket 232, a first cylinder 233, a cutting knife 234, two wire stripping knives 235, a second cylinder 236, and a wire stripping claw 237. The fixed base 231 is located on the wire outlet side of the wire moving mechanism 22. The bracket 232 is located on one side of the fixed base 231. The first cylinder 233 is arranged on the bracket 232 and is opposite to the first cylinder 233. The cutting knife 234 is connected to the output end of the first cylinder 233. Both cutting knives 234 are connected to the output end of the first cylinder 233 and are respectively located on both sides of the cutting knife 234. The second cylinder 236 is arranged on the bracket 232. The wire stripping claw 237 is connected to the output end of the second cylinder 236 and can be moved away from or close to the wire moving mechanism 22 under the drive of the second cylinder 236. Specifically, the length of the cutting knife 234 is greater than the length of the wire stripping knife 235, and the wire stripping claw 237 is a pneumatic finger.

[0036] In specific applications, the transfer mechanism 25 includes a linear transfer guide 251, a transfer gripper 252, and a transfer drive cylinder 253. The linear transfer guide 251 is installed on the workbench 1. The transfer gripper 252 is connected to the slider of the linear transfer guide 251. The output end of the transfer drive cylinder 253 is connected to the slider of the linear transfer guide 251. Specifically, the transfer gripper 252 is a pneumatic finger.

[0037] For the sake of convenience, the processing device 2 farther away from the pressing device 3 of the two processing devices 2 will be referred to as the first processing device, and the processing device 2 closer to the pressing device 3 of the two processing devices 2 will be referred to as the second processing device. The wire harness processed by the first processing device will be referred to as the first wire harness, and the wire harness processed by the second processing device will be referred to as the second wire harness.

[0038] When the crimping terminal machine is working, the first processing device and the second processing device work at the same time, and the wire moving mechanism 22 is in the first working state (that is, the linear guide rail of the wire moving mechanism 22 is parallel to the transmission direction of the wire feeding mechanism 21), and one end of the wire harness passes through the wire feeding mechanism 21 and the wire moving mechanism 22 in sequence; first, the wire feeding drive motor drives the two wire feeding wheels 211 to rotate in opposite directions, so that the wire harness is continuously transmitted to the direction of the cutting and stripping mechanism 23 and passed by the cutting and stripping mechanism 23. After the wire harness passes through the cutting and stripping mechanism 23 to a predetermined length, the wire feeding mechanism 21 pauses; secondly, the first cylinder 233 generates a driving force to drive the cutting knife 234 and the two stripping knives 235 to the fixed seat 231 at the same time. The two wire stripping knives 235 respectively cut off part of the sheath of the wire harness, and at the same time, the two wire moving clamps 228 drive the two clamps 228 to move toward each other to clamp the wire harness, and the wire stripping claws 237 also clamp the wire harness; again, the second cylinder 236 drives the wire stripping claws 237 to move away from the wire moving mechanism 22, and the mobile drive motor 227 drives the ball screw 225 to rotate, thereby driving the two wire moving clamps 228 on the moving plate 224 to move away from the cutting and stripping mechanism 23 through the ball nut 226, so that the rear end of the wire harness clamped by the wire stripping claws 237 is clamped by the two wire moving clamps 228. The wrapping skin at the front end of the wiring harness is peeled off; then, the rotating drive motor 222 drives the turntable 221 to rotate so that the wire moving mechanism 22 switches to the second working state (that is, the front end of the wire harness clamped by the two wire moving clamps 228 is facing the terminal punching mechanism 24), and the wire harness clamped by the two wire moving clamps 228 is moved to the corresponding position with the terminal punching mechanism 24 under the action of the moving drive motor 227, the ball screw 225, the ball nut 226 and the moving plate 224 so that the terminal punching mechanism punches the terminal at the front end of the wire harness. At the same time, the transfer drive cylinder 253 of the first processing device drives the transfer clamping claw 252 to correspond to the wire stripping clamping claw 237 and clamps the first wire harness and moves it to the position corresponding to the second The transfer clamp 252 of the processing device corresponds to the transfer clamp 252 of the second processing device, and the transfer clamp 252 clamps the first wire harness and the second wire harness at the same time and transfers them to the pressing device 3 to press and terminal the rear end of the first wire harness and the rear end of the second wire harness. After the front end of the wire harness clamped by the wire moving mechanism 22 is terminalized at the terminal terminal mechanism 24, the wire moving mechanism 22 resumes the first working state again, and the front end of the wire harness clamped by the two wire moving clamps 228 corresponds to the cutting and stripping mechanism 23 again under the action of the moving drive motor 227, the ball screw 225, the ball nut 226 and the moving plate 224. Finally, the above actions are repeated to realize the continuous processing and production of two-wire three-head wire harnesses.

[0039] It should be noted that when the crimping machine starts working, the front ends of the first wire harness and the second wire harness are not crimped with terminals respectively.

[0040] In some preferred embodiments, the wire moving mechanism 22 further includes a wire conduit 229, which is disposed on the movable plate 224. Specifically, there are two wire conduits 229, one on each side of the two wire moving clamps 228. The wire conduits 229 can effectively guide the wire harness provided by the wire feeder, thereby ensuring that the front end of the wire harness accurately corresponds to the cutting and stripping mechanism 23 and the terminal crimping mechanism 24.

[0041] like Figure 1 and Figure 5 As shown, in some preferred embodiments, the above-mentioned terminal crimping machine further includes a wire aligning device 4. The wire aligning device 4 includes a wire aligning clamp 41. The wire aligning clamp 41 is arranged on the workbench 1 and is located between the two processing devices 2 and the crimping device 3. The wire aligning clamp 41 has two claws arranged opposite to each other, and a wire aligning groove 411 is provided on the opposite sides of the two claws. In a specific application, after the transfer mechanism 25 of the second processing device clamps the first wire harness and the second wire harness, the first wire harness and the second wire harness are first transferred to the wire aligning device 4. The two claws of the wire aligning clamp 41 move toward each other, so that the rear ends of the first wire harness and the rear ends of the second wire harness are temporarily merged together under the action of the wire aligning groove 411. Then, the transfer mechanism 25 transfers the first wire harness and the second wire harness to the crimping device 3 for terminal crimping to ensure that the rear ends of the first wire harness and the rear ends of the second wire harness can be firmly pressed and fixed together by a terminal, thereby avoiding the situation where the rear ends of the first wire harness and the rear ends of the second wire harness are far apart and cannot be pressed and fixed together by a terminal.

[0042] In some preferred embodiments, the above-mentioned terminal crimping machine further includes a transfer device 5, which has the same structure as the transfer mechanism 25. In specific applications, the transfer jaws 252 of the transfer device 5 and the transfer mechanism 25 of the second processing device share the slider of the transfer linear guide 251, that is, the transfer drive cylinder 253 of the transfer mechanism 25 of the second processing device can drive the transfer jaws 252 of the transfer device 5 and the transfer jaws 252 of the transfer mechanism 25 of the second processing device to move synchronously, thereby reducing production costs. Specifically, the transfer mechanism 25 of the second processing device transfers the first wire harness and the second wire harness to the line-straightening device 4, and the transfer device 5 transfers the first wire harness and the second wire harness after the line-straightening device to the crimping device 3 for terminal crimping. In this way, compared with the transfer mechanism 25 of the second processing device first transferring the first wire harness and the second wire harness to the line-straightening device 4 and then transferring the first wire harness and the second wire harness to the crimping device 3 for terminal crimping, the processing efficiency is significantly improved.

[0043] like Figure 6As shown, in some preferred embodiments, the bracket 232 of the cutting and stripping mechanism 23 of the processing device 2 near the pressing device 3 is provided with two opposing guide pieces 238, with a guide gap formed between the two guide pieces 238. The ends of the two guide pieces 238 away from the pressing device 3 each have an inclined portion 2381, and the distance between the two inclined portions 2381 gradually decreases from away from the pressing device 3 to closer to the pressing device 3. In specific applications, the two guide pieces 238 can guide the first wire harness transferred by the transfer mechanism 25 of the first processing device, so that the first wire harness and the second wire harness can be accurately overlapped, thereby ensuring that the transfer clamping jaws 252 of the transfer mechanism 25 of the second processing device can accurately and simultaneously clamp the first and second wire harnesses.

[0044] like Figure 7 As shown, in some preferred embodiments, the above-mentioned terminal crimping machine further includes a blanking device 6, which includes a blanking drive motor 61, a rotating plate 62, and a blanking clamp 63. The blanking drive motor 61 is arranged on the crimping device 3. The rotating plate 62 is connected to the output shaft of the blanking drive motor 61. The blanking clamp 63 is arranged on the rotating plate 62. When the blanking drive motor 61 drives the rotating plate 62 to correspond to the crimping device 3, the blanking clamp 63 corresponds to the processing position of the crimping device 3. In a specific application, the crimping device 3 presses the rear end of the first wire harness and the rear end of the second wire harness together through a terminal to obtain a two-wire three-end wire harness. The terminal is rotated to correspond to the two-wire three-end wire harness, and the blanking clamp 63 clamps the two-wire three-end wire harness. Then, the blanking drive motor 61 drives the rotating plate 62 to rotate in the opposite direction to drive the blanking clamp 63 to rotate to the blanking end. The blanking clamp 63 releases the two-wire three-end wire harness. By overlapping the above actions, continuous blanking of the two-wire three-end wire harness can be achieved.

[0045] In actual applications, the processing device 2, the crimping device 3, the line assembly device 4, and the transfer device 5 are all electrically connected to the control system of the crimping machine. The control system of the crimping machine controls the operation of the processing device 2, the crimping device 3, the line assembly device 4, and the transfer device 5 to achieve the effect of automated control of the crimping machine. Of course, the control system of the crimping machine can be any one of an industrial computer, a PLC, or a single-chip microcomputer, and will not be described in detail here.

[0046] To sum up, in one or more embodiments of the present invention, the terminal crimping machine of the present invention cooperates with the crimping device through two processing devices, which can strip the wires and crimp the terminals at the front ends of the two wire harnesses respectively, and then strip the wires at the rear ends of the two wire harnesses respectively and crimp and fix the rear ends of the two wire harnesses together with a terminal to form a two-wire three-head wire harness to meet market demand.

[0047] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
