Description

Technical Field

[0001] This invention relates to the field of terminal crimping machines, and more particularly to a terminal crimping machine and crimping method for long wires. Background Technology

[0002] With the rapid development of high-end industrial product processing technology at home and abroad and the increasingly fierce market competition, controlling product quality has become the common pursuit of all enterprises, especially terminal crimping machines. A terminal crimping machine is a machine used in wire processing. It can crimp the metal head to the end of the wire and then make it conductive. The terminals crimped by the terminal crimping machine are usually for easier connection. They can stably connect two wires together without soldering, and can be easily pulled out when disconnecting.

[0003] The existing technology has the following shortcomings: The existing terminal crimping machine mainly places the wire on the winding wheel. During the crimping process, the wire is wound up and moves along with the winding wheel. The movement of the wire will pull the winding wheel to rotate. However, the wire will be subjected to tension when it is unwound by pulling the winding wheel. If the weight of the wire wound on the winding wheel is large, it may cause the wire core inside the wire to break. Furthermore, when the crimping assembly is in the crimping process, the wire stops moving. At this time, the winding wheel may continue to rotate due to inertia and unwound too much wire. If too much wire is unwound, the wire may become tangled on the terminal crimping machine or its components, which will not guarantee the stable operation of the terminal crimping machine. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a long wire terminal crimping machine and crimping method.

[0005] This invention solves the above-mentioned technical problems through the following technical means: a long wire terminal crimping machine, comprising a device body, on which a wire feeding assembly and a crimping assembly are disposed in corresponding positions. The wire feeding assembly is used for winding the wire and supplying the wire to the crimping assembly. After receiving the wire from the wire feeding assembly, the crimping assembly crimps a terminal onto the end of the wire. A controller is also fixedly disposed on the side of the device body, and a monitoring assembly is disposed at the bottom of the wire feeding assembly. The monitoring assembly sends an electrical signal to the controller according to the wire winding speed of the crimping assembly, and the controller controls the wire feeding speed of the wire feeding assembly to be equal to the wire winding speed of the crimping assembly.

[0006] Preferably, the wire feeding assembly includes a wire reel, a winding wheel, and a motor. The wire reel is fixedly connected to the equipment body via a support rod, the winding wheel is movably connected to the wire reel via a bearing, the motor is fixed to the back side of the wire reel via bolts, and the winding wheel and the motor are connected via an output shaft drive. The wire is manually wound around the outside of the winding wheel. In use, the motor drives the winding wheel to rotate and feed the wire, which is convenient for use.

[0007] Preferably, to facilitate wire winding, a wire clamp is also provided on the outside of the winding reel. The wire clamp includes a support plate, a slide rod, a pressure head, a first spring, and a tubular component.

[0008] Preferably, two support plates are fixed on the outer circumference of the winding reel, and the slide rod and the pipe fitting are respectively arranged between the two support plates. The slide rod is slidably connected to one support plate, and the pipe fitting is fixedly connected to the other support plate. A pressure head is fixedly provided at one end of the slide rod, and a first spring is sleeved on the outside of the slide rod. The first spring abuts against the pressure head, and the pressure head is embedded in the pipe fitting.

[0009] Preferably, the winding reel has several heating wires embedded inside, and the heating wires are centrally symmetrical about the winding reel. After the winding reel winds the wire, the heating wires are energized to heat the winding reel. The winding reel heats the wire, which softens the wire and makes it easier to process.

[0010] Preferably, the monitoring component includes a housing, a guide wheel, and a speed sensor. The guide wheel is movably mounted in the housing via an axle, and the speed sensor is fixed inside the guide wheel with its end in contact with the axle. The axle is fixedly connected to the housing, and the guide wheel is movably connected to the axle. A wire passes through the guide wheel and the housing and is fed into the crimping assembly. When the crimping assembly retracts the wire, the wire moves, causing the guide wheel to rotate, which in turn causes the internal speed sensor to rotate.

[0011] Preferably, an auxiliary wheel is provided on one side of the guide wheel, and the guide wheel is in contact with the auxiliary wheel. A bracket is movably provided on the outer side of both the guide wheel and the auxiliary wheel. The bracket is slidably connected to the box body through a support rod. A second spring is sleeved on the outer side of the support rod, and the second spring abuts against the bracket.

[0012] The present invention also provides a crimping method for a long wire terminal crimping machine, the crimping method comprising the following steps:

[0013] The wire is wound on the wire feeding assembly, passes through the monitoring assembly, and is then placed into the crimping assembly. The terminal crimping machine is controlled by the controller, and the crimping assembly crimps a terminal at the end of the wire. The monitoring assembly sends the crimping speed data of the crimping assembly to the controller, and the controller controls the wire feeding speed of the wire feeding assembly to be the same as the crimping speed of the crimping assembly.

[0014] The beneficial effects of this invention are:

[0015] 1. The present invention sends an electrical signal to the controller based on the wire take-up speed of the crimping component through the monitoring component. The controller controls the wire feeding speed of the wire feeding component to be equal to the wire take-up speed of the crimping component. The terminal crimping machine can effectively control the wire feeding speed to be equal to the wire take-up speed, thereby avoiding the wire from breaking due to pulling or excessive wire being released from the winding device, and ensuring the stable operation of the terminal crimping machine.

[0016] 2. In this invention, the sliding rod pulls the pressure head away from the pipe and embeds one end of the wire into the pipe. When the sliding rod is released, the first spring pushes the pressure head into the pipe. The pressure head clamps the wire into the pipe to fix the wire. The outer side of the winding wheel is provided with a wire clamp. After the wire clamp fixes one end of the wire, the wire can be wound by rotating the winding wheel, which facilitates the winding of the wire.

[0017] 3. The present invention embeds several heating wires inside the winding wheel, and the heating wires are centrally symmetrical about the winding wheel. After the winding wheel winds the wire, the heating wires are connected to electricity to heat the winding wheel. The winding wheel heats the wire, which softens the wire and makes it easier to process.

[0018] 4. In this invention, the speed sensor rotates and sends an electrical signal to the controller. After processing the electrical signal, the controller sends a command to the motor, so that the speed of the motor is the same as the speed of the guide wheel. In this way, the speed of the winding wheel and the guide wheel can be the same, thereby achieving the purpose of making the wire feeding speed of the wire feeding assembly the same as the wire taking-up speed of the crimping assembly.

[0019] 5. In this invention, the second spring pushes the guide wheel and the auxiliary wheel to press against the wire, so that the wire can be kept in contact with the guide wheel. Furthermore, the clamping of the guide wheel and the auxiliary wheel can make the curved wire flat, which is convenient for subsequent processing of the wire. Attached Figure Description

[0034] In use, the wire is placed on the direction component 3, passed through the monitoring component 5, and then placed on the crimping component 4 to crimp the terminal.

[0038] Please see Figure 1 As shown, unlike the prior art, the device body 1 is also fixedly provided with a controller 2 on its side, and the bottom of the wire feeding assembly 3 is also provided with a monitoring assembly 5. The monitoring assembly 5 sends an electrical signal to the controller 2 according to the wire take-up speed of the crimping assembly 4, and the controller 2 controls the wire feeding speed of the wire feeding assembly 3 to be equal to the wire take-up speed of the crimping assembly 4.

[0039] In use, the wire is placed on the direction component 3, passed through the monitoring component 5, and then placed on the crimping component 4 to crimp the terminal. During the crimping process, the monitoring component 5 sends an electrical signal to the controller 2 according to the wire take-up speed of the crimping component 4.

This terminal crimping machine can effectively control the wire feeding speed to be equal to the wire take-up speed, thereby avoiding the wire from breaking due to pulling or excessive wire being released from the winding device, and ensuring the stable operation of the terminal crimping machine.

[0040] Please see Figure 2 As shown, in this embodiment, the wire feeding assembly 3 includes a wire reel 31, a winding wheel 32, and a motor 33. The wire reel 31 is fixedly connected to the device body 1 via a support rod, and the winding wheel 32 is movably connected to the wire reel 31 via a bearing. The motor 33 is fixed to the back side of the wire reel 31 by bolts, and the winding wheel 32 and the motor 33 are connected by an output shaft drive. The wire is manually wound around the outside of the winding wheel 32. In use, the motor 33 drives the winding wheel 32 to rotate and feed the wire, which is convenient for use.

[0041] Please see Figure 4As shown, to facilitate wire winding, a wire clamping component 322 is also provided on the outside of the winding reel 32. The wire clamping component 322 includes a support plate 3221, a sliding rod 3222, a pressure head 3223, a first spring 3224, and a tubular component 3225.

[0042] Two support plates 3221 are fixed to the outer circumference of the winding reel 32. The slide rod 3222 and the pipe fitting 3225 are respectively arranged between the two support plates 3221. The slide rod 3222 is slidably connected to one support plate 3221, and the pipe fitting 3225 is fixedly connected to the other support plate 3221. One end of the slide rod 3222 is fixedly provided with a pressure head 3223, and a first spring 3224 is sleeved on the outside of the slide rod 3222. The first spring 3224 abuts against the pressure head 3223, and the pressure head 3223 is embedded in the pipe fitting 3225.

[0043] In use, the operator manually pulls the pressure head 3223 away from the tube 3225 using the slide bar 3222, and inserts one end of the wire into the tube 3225. When the slide bar 3222 is released, the first spring 3224 pushes the pressure head 3223 into the tube 3225. The pressure head 3223 clamps the wire into the tube 3225 to fix the wire. The outer side of the winding wheel 32 is provided with a wire clamp 322. After the wire clamp 322 fixes one end of the wire, the wire can be wound by rotating the winding wheel 32, which facilitates the winding of the wire.

[0044] To make the wire more flexible and easier to process, we also embed several heating wires 321 inside the winding wheel 32. The heating wires 321 are centrally symmetrical about the winding wheel 32. After the winding wheel 32 winds the wire, the heating wires 321 are energized to heat the winding wheel 32. The winding wheel 32 heats the wire, which softens the wire and makes it easier to process.

[0045] Example 3

[0046] In order to enable the monitoring component 5 to monitor the moving speed of the conductor, this embodiment mainly optimizes the structure of the monitoring component 5, as follows:

[0047] Please see Figure 3As shown, the monitoring component 5 includes a housing 51, a guide wheel 52, and a speed sensor 53. The guide wheel 52 is movably mounted in the housing 51 via a wheel axle. The speed sensor 53 is fixed inside the guide wheel 52, and the end of the speed sensor 53 is in contact with the wheel axle. The wheel axle is fixedly connected to the housing 51, and the guide wheel 52 is movably connected to the wheel axle. The wire passes through the guide wheel 52 and the housing 51 and is fed into the crimping component 4. When the crimping component 4 retracts the wire, the wire moves, which drives the guide wheel 52 to rotate. The guide wheel 52 drives the speed sensor 53 inside to rotate. The speed sensor 53 sends an electrical signal to the controller 2. After processing the electrical signal, the controller 2 sends a command to the motor 33, so that the rotation speed of the motor 33 is the same as the rotation speed of the guide wheel 52. In this way, the rotation speed of the winding wheel 32 and the guide wheel 52 can be the same, thereby achieving the purpose of the wire feeding speed of the wire feeding component 3 being the same as the wire taking-up speed of the crimping component 4.

[0048] Furthermore, to ensure that the wire and guide wheel 52 remain in contact, an auxiliary wheel 54 is provided on one side of the guide wheel 52, and the guide wheel 52 and the auxiliary wheel 54 are in contact. A bracket 55 is movably provided on the outer side of both the guide wheel 52 and the auxiliary wheel 54. The bracket 55 is slidably connected to the housing 51 through a support rod 57. A second spring 56 is sleeved on the outer side of the support rod 57, and the second spring 56 abuts against the bracket 55. When the wire is inserted into the gap between the guide wheel 52 and the auxiliary wheel 54, the second spring 56 pushes the guide wheel 52 and the auxiliary wheel 54 to abut against the wire. This keeps the wire in contact with the guide wheel 52, and the clamping of the guide wheel 52 and the auxiliary wheel 54 makes the curved wire flat, which is convenient for subsequent processing of the wire.
