Description

Technical Field

[0001] The invention belongs to the technical field of terminal crimping machines, and in particular relates to a double-port terminal crimping machine. Background Art

[0002] The terminal crimping machine is a combination of equipment used to crimp terminals and insert plastic shells into wires. It includes multiple processes such as wire feeding, wire cutting, stripping, tinning, crimping terminals, and inserting plastic shells. Among them, the stripping process is a key link before crimping terminals. The rubber at the end of the wire needs to be accurately cut and peeled off to expose the fiber core, laying the foundation for subsequent tinning, terminal crimping and other processes.

[0003] Currently, the stripping process of traditional terminal crimping machines generally adopts a single-wire processing mode, that is, the insulation layer of only one wire can be stripped at a time. From the perspective of process connection, single-wire stripping needs to be matched one by one with the wire feeding, wire cutting and other links. Each time the stripping of a wire is completed, it is necessary to wait for the material delivery of the previous process and the preparation of the subsequent process. For example, in the production of electronic wire harnesses, after the equipment completes the stripping of a wire, the wire feeding mechanism needs to be restarted to deliver the next wire, and the wire cutting mechanism also needs to adjust the parameters again for cutting. The idling waiting time of the equipment in the entire process accounts for a significant proportion, which seriously reduces the effective output per unit time and greatly reduces the processing efficiency. Summary of the Invention

[0004] The object of the present invention is to provide a double-port terminal crimping machine to solve the problems raised in the above background technology.

[0031] The present invention provides Figure 1-7 A double-port terminal crimping machine is shown, comprising:

[0032] A machine base 1, with a processing table 2 connected to the top of the machine base 1;

[0033] The wire stripping mechanism is provided with several groups and all of them are provided on the processing table 2, and are used for stripping the wires to be processed. The wire stripping mechanism includes a mounting frame 3, the mounting frame 3 is connected to the machine base 1 and the mounting frame is slidably connected to the Y-axis movable frame 4, the Y-axis movable frame 4 is connected to the vertical plate 5 and the top end of the vertical plate 5 passes through the top of the processing table 2, and two groups of protective clamping shells 6 are rotatably connected to the top end of the vertical plate 5 and a conical push rod 7 is provided between the two groups of protective clamping shells 6, the top of the conical push rod 7 is provided with a cutter 8 and the cutter 8 is provided with two groups of V-shaped blade grooves 9, and the conical push rod 7 is pushed toward the cutter 8 so that the conical push rod 7 cooperates with the blade groove 9 to shear the wire.

[0034] A toothed belt 10 is connected to the Y-axis moving frame 4 , a first servo motor 11 is provided on the mounting frame 3 , and a gear 12 is connected to the output shaft of the first servo motor 11 , and the gear 12 is meshed with the toothed belt 10 .

[0035] A cylinder 13 is provided on the vertical plate 5 , and a piston rod of the cylinder 13 is connected to the tapered push rod 7 .

[0036] The processing table 2 is connected to a plurality of fixing frames 14 , and a plurality of cutters 8 are respectively connected to the fixing frames 14 . The processing table 2 is also connected to a bracket 15 , and one end of the bracket 15 is connected to a control box 16 .

[0037] A wire feeder 17 is connected to one side of the processing table 2, and a number of guide rollers 18 are connected to the wire feeder 17 through a rotating shaft. The guide rollers 18 can rotate flexibly around the rotating shaft. When the wires are transported, the guide rollers 18 will rotate synchronously with the movement of the wires, converting the sliding friction between the wires and the wire feeder 17 into rolling friction between the rollers and the wires. For wire stripping mechanisms at different positions, the wire feeder 17 can be set according to needs, and the wire feeder 17 and the machine base 1 are detachably connected, such as fixed by bolts. When it is necessary to adjust the position of the wire feeder 17 or increase the wire feeder 17 to adapt to different groups of wire stripping mechanisms, the wire feeder 17 can be installed on the machine base 1 by bolts.

[0038] A cabinet 21 is hingedly connected to the machine base 1 , and a front cover 28 is connected to the top of the processing table 2 .

[0039] The bottom of the machine base 1 is connected to a number of foot supports 19. In some places with uneven ground, the height of each foot support 19 can be adjusted individually to keep the equipment stable and avoid unstable operation of the equipment due to tilted ground. The bottom of the machine base 1 is also rotatably connected to a number of universal wheels 20. The universal wheels 20 can make the equipment more convenient to change position when it needs to be changed. There is no need for large lifting equipment, and the operator can easily push the equipment to move.

[0040] Two sets of terminal machines 26 are provided on the top of the processing table 2 , and the terminals are pressed onto the conductors of the wires through the pressing heads of the terminal machines 26 .

[0041] A tube heating machine 27 for heating the heat shrink tube at the joint between the wire and the terminal is provided at one end of the top of the processing table 2 , and a heating controller 30 is provided on one side of the tube heating machine 27 .

[0042] A protective shell 29 is provided on the top of the processing table 2 and at one end of the wire feeding frame 17, and an X-axis servo screw linear module 25 is provided in the protective shell 29, and the X-axis movable slide of the X-axis servo screw linear module 25 is connected with a movable seat, and a mounting plate 22 is provided on one side of the protective shell 29, and a plurality of rollers 24 for conveying wires are rotatably connected on the mounting plate 22, and a second servo motor 23 is provided on one side of the mounting plate 22, and the output shaft of the second servo motor 23 is connected to the plurality of rollers 24 for transmission. When the wire to be processed enters the wire feeding frame 17, it will first move toward As the wire is transported to the stripping station, the protective housing 29 at one end of the wire feeding frame 17 comes into play first, and the wire is guided to the roller 24 through the movable seat on the X-axis servo screw linear module 25, preparing for the subsequent wire stripping process. After the second servo motor 23 on the protective housing 29 is started, its output shaft transmits power to all rollers 24 through transmission structures such as sprockets and chains, so that the rollers rotate synchronously. The rotating rollers use the friction between the wires to drive the wires forward, and transport the wires to the stripping station, providing reliable pre-protection for the subsequent wire stripping process.

[0043] After the double-port terminal crimping machine is powered on, the control box 16 enters the standby state, and the operator completes the preset processing parameters through the control interface. The wire coil to be processed is placed on one side of the wire conveyor 17, and the wire end is introduced between the guide rollers 18 on the wire conveyor 17. The guide rollers 18 rotate themselves under the drive of the external drive device, and at the same time, with the help of the friction with the surface of the wire, the wire is smoothly conveyed toward the processing table 2. When the front end of the wire approaches the processing table 2, the first servo motor 11 receives the control signal and starts, and the output shaft of the first servo motor 11 drives the gear 12 to start rotating. Since the gear 12 is tightly meshed with the toothed belt 10 on the inner side of the Y-axis moving frame 4, the rotational force of the gear 12 is converted into the linear motion of the toothed belt 10, thereby driving the Y-axis moving frame 4 to slide along the slide rail on the mounting frame 3. A wear-resistant slider is provided at the bottom of the Y-axis moving frame 4 where it contacts the slide rail, which not only ensures smooth movement but also reduces wear after long-term use. As the Y-axis moving frame 4 moves, the vertical plate 5 connected thereto and the wire stripping mechanism on the vertical plate 5 move synchronously until the center of the wire stripping mechanism and the axis of the wire to be processed are in the same horizontal plane, and the opening of the protective clamping shell 6 is facing the wire conveying path.

[0044] Then the piston rod of the cylinder 13 on the vertical plate 5 extends out, pushing the tapered push rod 7 to move upward. The front end of the tapered push rod 7 is conical, and its axis is aligned with the center line of the blade groove 9 of the cutter 8. As the push rod is pushed forward, the wire is pushed into the V-shaped blade groove 9 in the cutter 8. The blades on both sides of the blade groove 9 are symmetrically distributed, which can form a shear force when contacting the outer skin of the wire. When the tapered push rod 7 pushes the wire into the blade groove 9 to a certain depth, the blade contacts the outer skin of the wire and gradually cuts in. Due to the V-shaped design of the blade groove 9, the blade has a strong impact on the wire during the cutting process. The force acting on the outer skin gradually increases until the outer skin is cut off. After the outer skin is cut off, the piston rod of the cylinder 13 drives the conical push rod 7 to retract. At this time, the guide roller 18 of the wire conveying frame 17 is started again to convey the stripped wire forward for a distance, so that the unprocessed part enters the processing area, and the stripped part is sent to the entrance of the next process. The Y-axis moving frame 4 returns to its initial position under the drive of the servo motor 11, waiting for the next wire to be delivered to its place, and repeats the above clamping and stripping process to form a continuous processing cycle.

[0045] The stripped wires will be transported forward manually, and the terminal machine 26 will transport the terminals to the designated position below the pressing head through a preset feeding mechanism. Under the coordination of the controller, the central axis of the terminal is consistent with the axis of the fiber core of the wire after stripping, preparing for subsequent pressing. When the fiber core of the wire is fully aligned with the terminal, the pressing head of the terminal machine 26 moves downward under the action of a driving device (such as a cylinder or a servo motor). The pressing head will apply a preset pressure to tightly press the terminal onto the fiber core of the stripped wire. During the pressing process, it is ensured that the terminal is firmly connected to the fiber core. After completing a set of terminal pressing, the operator will transport the pressed wires into the tube baking machine 27. The operator can pre-sleeve the heat shrink tubing near the pressing point between the wire and the terminal. When the wire with the terminal is manually transported to the entrance of the tube baking machine 27 The operator can preset the heating temperature and heating time through the heating controller 30. Different specifications of heat shrink tubing correspond to different heating parameters. After the tube baking machine 27 is started, heat will be generated by the built-in heating element (such as a hot air device or an infrared heater). The heat acts evenly on the heat shrink tubing, causing it to shrink. During the heating process, the heating controller 30 will monitor the temperature in real time. Once it reaches the preset value, it will remain stable to avoid damage to the wire core or terminal due to excessively high temperature, or insufficient temperature affecting the shrinkage effect of the heat shrink tubing. After the heat shrink tubing is completed, the wire will be manually conveyed forward and leave the heating area of ​​the tube baking machine 27. After natural cooling, the heat shrink tubing will be tightly wrapped around the connection between the terminal and the wire to form insulation and protection. Subsequently, the processed wire will be conveyed to the equipment outlet, completing the entire processing flow.
