Description

Technical Field

[0001] The utility model relates to the technical field of terminal machines, and specifically relates to a fully automatic ultra - silent terminal machine. Background Technique

[0002] The silent terminal machine used in wire processing is a machine that presses a metal head onto the wire end and then conducts electricity. The terminals produced by the silent terminal machine are usually for more convenient connection. Without welding, two wires can be stably connected together, and when disassembling, only need to unplug. The ultra - silent terminal machine adopts modern frequency converter control technology and is suitable for the crimping of various terminals and wires. Digital control, safety protection system, and simple operation achieve the precision, strength, and safety that machinery cannot reach; it enables the terminal machine to operate ultra - silently. The frequency converter itself can save 30% of electricity. Coupled with the fact that the ultra - silent terminal machine is powered on once for each operation, eliminating the unnecessary idling of the motor, it is more power - saving. Without noise, workers can work more attentively, greatly improving work efficiency. This is the preferred equipment for wire end processing.

[0003] For example, a Chinese invention with the publication number CN221126502U and the publication date of June 11, 2024 discloses an ultra - silent terminal machine, including a material placement plate. One side of the material placement plate is provided with a terminal machine base. One side on the terminal machine base is provided with a terminal machine body. One side of the top of the terminal machine body is provided with a lighting lamp, and the lighting lamp is fixed on the top of the terminal machine body through a universal rod. The other side of the top of the terminal machine body is installed with a servo motor. This application can stack the wire to be processed flat in the coil placement rack in the coil placement groove, which is convenient for taking, improving the efficiency of taking and processing. It is convenient to adjust the specific positions of the two sliders in the chute of the material placement plate, facilitating different production personnel to take the terminal wire. The distance between the two sliders can also be quickly adjusted by adjusting the limit bolt, so that the coil placement rack can place wire coils of different diameters. The operation is simple and the function is practical.

[0004] It can be seen from the above patents that currently, for the ultra - silent terminal machine, wire taking and placing still need to be done manually, with low operation efficiency and prone to safety accidents. Therefore, a fully automatic ultra - silent terminal machine is needed. Summary of the Invention

[0033] Referring to Figure 1 , a fully automatic ultra-quiet terminal machine disclosed by the present utility model includes a wire conveying system 1, a skin cutting mechanism 2, a peeling mechanism 3, a terminal pressing machine 4, a robotic arm 5, and a control system 6.

[0034] The wire conveying system 1 includes a wire coil 11, a wire hole 12, and a double-row roller wire feeding device 13. The wire conveying system 1 is used to convey wires to the skin cutting mechanism 2. The gap between the two rows of rollers of the double-row roller wire feeding device 13 is adjustable and is only the diameter size of a single wire, so that the wire can just pass through the gap between the two rows of rollers and the wire can be pressed into a straight strip; the wire hole 12 and the gap between the upper and lower rollers are on the same horizontal line to guide the wire to pass through the rollers in a straight line.

[0035] The skin cutting mechanism 2 includes a lower knife fixing seat 21, a lower cutting knife 22, an upper cutting knife 23, an upper knife fixing seat 24, and a press 25, and is used to cut off the insulating skin on the surface of the wire, that is, the outer skin, and cut the wire into individual wires; both the lower cutting knife 22 and the upper cutting knife 23 of the skin cutting mechanism 2 are double-edge structures. The front edge is a flat mouth cutting structure, and the upper and lower parts are in seamless contact, and are used to cut the wire into individual wires as a whole; the rear edge is a circular or square cutting structure corresponding to the shape of the wire, and the upper and lower gaps of the rear edge are the diameter of the wire core in the middle of the wire, and are used to cut off the insulating skin on the surface of the wire.

[0036] The peeling mechanism 3 is used to peel the wire after skin cutting; the lower cutting knife edge of the lower cutting knife assembly and the upper cutting knife edge of the upper cutting knife assembly correspond to each other, and the upper and lower gaps are the diameter of the wire core in the middle of the wire, so that after pressing down corresponding to the previous cutting position, only the insulating skin on the surface of the wire can be cut just right. The wire is clamped by the rotating assembly and rotated by 180° to ensure that the insulating skin on the surface of the wire is completely cut off.

[0037] The terminal pressing machine 4 is used to press the terminals onto the peeled wires; the terminal conveying chain is used to convey one terminal to the pressing die, and a circulating terminal conveying chain is formed after passing through the pressing die; the pressing mechanism is used to press the terminals onto the specified positions of the wires, and the collecting box is used to collect the wires with the terminals pressed, that is, the products.

[0038] The robot arm 5 is arranged and moves between the skin cutting mechanism 2, the stripping mechanism 3 and the terminal crimping machine 4, and is used to connect various process steps and fix the wires during the process steps; the control system 6 includes a control unit 61 and a display 62, and the control unit 61 is used to control the robot arm 5.

[0039] In an optional embodiment, if single-end stripping is required, each wire only needs to pass through the cutting mechanism 2, the stripping mechanism 3 and the terminal crimping machine 4 once respectively, so that each wire can be cut once, cut once, stripped once, and crimped once, that is, there is only one terminal on the wire containing the terminal after completion; if double-end stripping is required, each wire needs to pass through the cutting mechanism 2, the stripping mechanism 3 and the terminal crimping machine 4 twice respectively, so that each wire can be cut twice, cut twice, stripped twice, and crimped twice, that is, there are 2 terminals on the wire containing the terminal after completion.

[0040] The working process of this embodiment is as follows:

[0041] The wire coil 11 enters between the upper and lower double-row rollers of the double-row roller feeding device 13 in the horizontal direction through the wire hole 12, and is pressed into a straight wire strip, and is transported to the front end of the skin cutting mechanism 2. The straight wire strip is grabbed by the robot arm 5 and placed in the skin cutting mechanism 2. Under the action of the press 25, the double blades of the lower cutter 22 and the upper cutter 23 of the skin cutting mechanism 2 cut one end of the straight wire strip, and the other end is fixed in parallel by the robot arm. The front blade of the flat cutting structure cuts off the straight wire strip as a whole, while the rear blade of the circular cutting structure cuts off the insulating skin on the surface of the straight wire strip. Then, the robot arm 5 puts the skin-cut straight wire strip into the stripping mechanism 3, and the lower cutter assembly and the upper cutter assembly press the skin-cut straight wire strip tightly, and the lower cutter blade cuts the skin of the straight wire strip. The upper and lower gaps between the upper and lower cutting blades are the diameter of the center core of the conductor, so that when the front incision position is aligned and pressed down, only the insulating skin on the surface of the conductor is cut. The rotating assembly clamps the cut straight strip conductor and rotates 180° to ensure that the insulating skin on the surface of the conductor is completely cut off; the robot arm 5 then pulls the cut and stripped straight strip conductor out of the rotating assembly, and the insulating skin on the surface of the conductor remains in the rotating assembly and is subsequently ejected; the terminal conveying chain of the terminal crimping machine 4 places the terminal on the crimping mold, and the robot arm 5 places the cut and stripped straight strip conductor on the terminal in the crimping mold, and the crimping mechanism crimps the terminal on the cut and stripped straight strip conductor; the robot arm 5 then puts the wire after the terminal is crimped into the collection box.

[0042] Of course, the embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
