Description

Technical Field

[0001] The invention relates to the technical field of terminal pressing, and in particular to an automatic pressing device for double-headed terminals. Background Art

[0002] Double-ended terminals refer to an electrical connector that is usually used to connect the two ends of a wire or conductor so that it can be connected to an electronic device, electrical equipment, or circuit. Because double-ended terminals can be customized in size and shape, they are suitable for a variety of indoor and outdoor environments, including industrial equipment, consumer electronics, automotive electronics, and other fields.

[0003] In short, as a common form of electrical connector, the design and use of double-headed terminals make them an indispensable part of electronic and electrical engineering, which can effectively connect and transmit electrical signals and power.

[0004] Terminal crimping refers to an electrical connection technology, a process used to fix wires or conductors to electrical connectors or terminals. This technology establishes an electrical connection by pressing (or crimping) the contact between the wire and the terminal, ensuring a reliable and stable connection.

[0005] Terminal crimping is widely used in various electrical equipment and industries, such as automobile manufacturing, electronic equipment manufacturing, power systems, etc. It is one of the key steps to ensure the quality and stability of electrical connections.

[0006] The advantage of terminal crimping technology is that it can achieve efficient mass production while ensuring the stability and safety of the connection. Correct crimping operation can reduce connection impedance, electrical failures and maintenance costs, thereby improving the overall electrical system performance and reliability.

[0007] Before crimping the terminal on the wire harness, after stripping one end of the wire harness, the exposed conductors may be arranged unevenly or crossed. Since traditional terminal crimping equipment usually cannot ensure the neatness and arrangement order of each conductor in the wire harness, the terminal may not be able to correctly connect each conductor during crimping, thus affecting the stability and reliability of the connection.

[0008] In summary, the prior art lacks a technology for arranging the conductors of the wire harness before crimping the terminals. Summary of the invention

[0009] The purpose of the present invention is to solve the shortcomings of the background technology and to propose an automatic double-head terminal pressing device.

At the same time, after the crimping is completed, automatic unloading is achieved, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Then, when the wire harness 5 is located directly above, the electric push rod 701 is used to drive the adjustment seat 7 to approach the wire harness 5, and then the motor B802 is used to drive the roller 801 to rotate. At this time, the roller 801 will drive the transmission wire-laying belt 8 to rotate, and then the upper and lower transmission wire-laying belts 8 will drive the wire-laying comb 803 to comb the exposed and messy conductors at the end of the wire harness 5;

[0044] Then, under the action of the spring 904, the two leveling coating strips 901 can be pressed on the conductor exposed at the end of the wiring harness 5, and the conductor is flattened when moving. At the same time, under the action of the rack 702, the L-shaped rod 909 connected to the transmission wheel 911 is rotated, so that the L-shaped rod 909 drives the pull rod 910, and the pull rod 910 drives the piston rod 908 to move back and forth, so that the piston rod 908 extracts the solder paste in the solder paste seat 804, and then injects it into the leveling coating strip 901 through the guide tube 905, and then the solder paste is evenly coated on the conductor exposed at the end of the wiring harness 5 through the sponge strip 906;

[0045] Then, when the wire feeding wheel 4 continues to rotate, it will drive the sorted wire harness 5 to rotate to the terminal crimping machine 2, and the terminal and the wire harness 5 will be crimped by the terminal crimping machine 2. When the wire harness 5 with the crimped terminal rotates to the lower side, the two wire clamping frames 1003 will separate, so that the wire harness 5 falls into the material receiving seat 102 for collection.
