Description

Technical Field

[0001] The invention relates to the field of wire and cable branching, in particular to a three-station automatic machine for branching, cutting, tinning and terminal crimping. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts; one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] However, when conducting three-station branching of wires and cables, there is often a disadvantage that the plastic sheath and metal debris cannot be quickly cleaned, which not only causes the table to be dirty, but also has many negative effects on the production environment and personnel. From a psychological perspective, a messy working environment can easily make operators irritable, reduce their work enthusiasm and concentration, and thus increase the probability of operational errors. From a production safety perspective, scattered metal debris may enter the transmission parts or electrical systems of the equipment, causing equipment failure or even safety accidents such as short circuits. Excessive accumulation of plastic sheaths can easily block the waste transmission channel and affect the normal operation of the equipment. In addition, waste that is not cleaned for a long time may breed bacteria, attract pests, and destroy the sanitary environment of the production workshop, which does not meet the cleanliness and safety requirements of modern industrial production. Therefore, technical personnel in this field provide a three-station branching cutting, tinning and terminal crimping special automatic machine to solve the problems raised in the above background technology. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In view of the shortcomings of the existing technology, the present invention provides a three-station automatic machine for wire cutting, tinning and terminal crimping, which solves the problem of inconvenience in quickly cleaning impurities on the table.

[0006] (2) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A three-station automatic machine for wire cutting, tinning, and terminal crimping, comprising a table, an orientation adjustment mechanism, a wire holder, a wire crimping mechanism, a fixing seat, a cutting mechanism, a tinning mechanism, a feeding mechanism, a wire pulling mechanism, and a cleaning mechanism. The cleaning mechanism comprises a plate rack fixedly connected to the top of the table, a third L-shaped plate fixedly connected to the side of the plate rack, two third L-shaped plates, the tops of the two third L-shaped plates fixedly connected to a cover body, the side of the cover body fixedly connected to a pipe, the pipe having multiple air outlets, all located in areas prone to impurities;

[0009] The top of the plate frame is overlapped with a bellows, and the plate frame and both sides of the bellows are fixedly connected with mounting blocks, and there are four mounting blocks, and screws are threadedly connected to the inside of the two groups of mounting blocks, and the side of the bellows is fixedly installed with a driving motor through a mounting plate, and the side of the bellows is fixedly connected with a third bearing, and the inside of the third bearing is rotatably connected to a third rotating shaft, one end of the third rotating shaft is fixedly connected to the output shaft of the driving motor, and the surface of the third rotating shaft is fixedly connected with fan blades, and there are six fan blades. A mesh cover is provided inside the bellows, and the top of the table is fixedly connected with a fixing seat, and a terminal punching device body is fixedly installed on the side of the fixing seat, and a wire feeding device body is fixedly installed on the top of the table;

[0010] Through the above technical solution, by setting up a cleaning mechanism, the driving motor can drive the fan blades to rotate, generating airflow in the bellows, and transporting it to various impurity generating areas (such as line dividing and cutting stations) through the pipe. The wind force blown out of the air outlet is used to blow impurities such as plastic skins and metal debris into the waste trough. At the same time, the cleaning mechanism uses a combination of the plate frame, the third L-shaped plate, the cover body and the pipe to accurately set the pipe air outlet in the area where impurities are easily generated, such as near the line dividing and cutting stations. This directional cleaning design can blow plastic skins, metal debris, etc. away from the working area in time at the source of waste generation, prevent waste accumulation from affecting equipment operation and product quality, and ensure the cleanliness of the processing environment. The bellows and the plate frame are connected by mounting blocks and screws to form a modular structure. When the driving motor, fan blades or mesh cover inside the bellows need to be maintained, During maintenance and cleaning, the operator can easily remove the screws, separate the bellows and the plate frame, and conveniently carry out internal inspection and component replacement, which reduces the maintenance difficulty and maintenance cost of the equipment and improves the maintainability of the equipment. By setting the azimuth adjustment mechanism, the stepper motor can drive the threaded rod to realize the lateral movement of the wire seat, and with the three wire troughs, multiple cables can be processed at the same time. By setting the wire pressing mechanism, the first hydraulic cylinder can drive the wire pressing plate to ensure that the cable is fixed and stable during the processing. By setting the cutting mechanism, the dual electric push rods can synchronously drive the cutting knife to improve the cutting accuracy. By setting the tinning mechanism, the servo motor can control the rotation angle, and multiple electric push rods can cooperate to realize the wire clamping and tinning operations. By setting the feeding mechanism and the wire pulling mechanism, the hydraulic system can be used to realize the terminal feeding and cable pulling functions respectively.

[0011] Furthermore, the azimuth adjustment mechanism includes a support base fixedly connected to the top of the table, the side of the support base is fixedly installed with a stepping motor through a mounting bracket, both sides of the support base are fixedly connected to a first bearing, the interiors of the two first bearings are rotatably connected to a first rotating shaft, one end of one of the first rotating shafts is fixedly connected to the output shaft of the stepping motor, one end of the two first rotating shafts is fixedly connected to a threaded rod, the surface of the threaded rod is threadedly connected to a first fixed block, support rods are fixedly connected to both sides of the inner wall of the support base, there are two support rods, the surfaces of the two support rods are slidably connected to a second fixed block, the two second fixed blocks are fixedly connected to a wire seat with the top of the first fixed block, and the top of the wire seat is provided with a wire groove, and there are three wire grooves;

[0012] Through the above technical solution, the azimuth adjustment mechanism adopts a design in which a stepper motor drives the threaded rod to rotate synchronously, which is connected to the first rotating shaft on one side through a coupling. The first rotating shaft then drives the threaded rod on the other side to rotate synchronously through a synchronous transmission structure. The threaded rod design makes the wire seat evenly stressed during movement, avoiding the offset problem caused by unilateral force, and improving the straightness and stability of the wire seat movement. At the same time, the double support rods on both sides of the inner wall of the support seat and the second fixed block constitute a linear guide system. When the stepper motor drives the threaded rod to rotate, the first fixed block moves along the axial direction of the threaded rod, and the second fixed block slides on the support rod. This dual-guide rail design effectively constrains the movement trajectory of the wire seat, prevents it from lateral offset or shaking, ensures that the wire seat moves linearly in the horizontal direction, and improves the accuracy of azimuth adjustment.

[0013] Furthermore, the wire pressing mechanism includes a fixing frame fixedly connected to the top of the wire seat, a first hydraulic cylinder is fixedly installed on the top of the fixing frame, a first hydraulic rod is fixedly installed inside the first hydraulic cylinder, and a wire pressing plate is fixedly connected to the bottom end of the first hydraulic rod;

[0014] Through the above technical solution, the design of the first hydraulic cylinder driving the first hydraulic rod is adopted, and the incompressible characteristics of the liquid are used to achieve precise force transmission. The hydraulic system can provide a large clamping force, usually up to 500-2000N, and the pressure output is stable, ensuring that the wire will not loosen due to external vibration or impact during the wire processing process, effectively ensuring the processing quality.

[0015] Furthermore, the cutting mechanism includes a fixed plate fixedly connected to the side of the fixed seat, a first electric push rod is fixedly installed on the top of the fixed plate, there are two first electric push rods, the bottom ends of the two first electric push rods are fixedly connected to a cutting knife, and the top of the table is fixedly connected to a cutting table;

[0016] Through the above technical solution, two first electric push rods are used to synchronously drive the cutting knife to ensure that the knife is evenly stressed during the cutting process, avoiding cutting deviations caused by unilateral force. The synchronous control accuracy of the dual push rods can reach ±0.03mm, so that the cutting knife always remains in a horizontal state, effectively improving the flatness and verticality of the cut surface. At the same time, the two electric push rods can be controlled independently or work together. In actual applications, the synchronous action of the dual push rods is achieved through the PLC control system, and the stroke and thrust of the push rods can be adjusted according to the material and diameter of the wire. For example, for harder wires, the thrust of the push rod can be increased, and for thin-diameter wires, the stroke can be reduced to avoid excessive cutting.

[0017] Furthermore, the tinning mechanism includes a servo motor fixedly mounted on the side of the fixing seat by a mounting frame, second bearings are fixedly connected to both sides of the fixing seat, a second rotating shaft is rotatably connected inside the two second bearings, one end of the second rotating shaft is fixedly connected to the output shaft of the servo motor, the other end of the second rotating shaft is fixedly connected to a first L-shaped plate, a second electric push rod is fixedly mounted on the side of the first L-shaped plate, one end of the second electric push rod is fixedly connected to a support plate, a square plate is fixedly connected to the side of the support plate, a support block is fixedly connected to the side of the square plate, there are two support blocks, a third electric push rod is fixedly mounted inside the two support blocks, and one end of the two third electric push rods is fixedly connected to a wire clamping plate;

[0018] Through the above technical solution, the servo motor drives the second rotating shaft to realize rotational motion through the second bearing. The rotation angle range can reach 0-360°, and the positioning accuracy is ±0.05°. This design enables the mechanism to accurately deliver the end of the wire into the tin storage box, and can adjust the tinning angle according to process requirements to adapt to wires of different specifications and shapes. At the same time, the servo motor and the electric push rod are coordinated through the PLC control system to execute the preset tinning trajectory program. For example, during the tinning process, the servo motor drives the wire to rotate 180°, and the second electric push rod performs reciprocating motion to make the tinning layer more uniform, and the thickness deviation is controlled within ±0.01mm.

[0019] Furthermore, the feeding mechanism includes a second hydraulic cylinder fixedly mounted on the top of the fixed seat, a second hydraulic rod fixedly mounted inside the second hydraulic cylinder, one end of the second hydraulic rod fixedly connected to a second L-shaped plate, a side of the second L-shaped plate fixedly connected to a connecting plate, a fourth electric push rod fixedly mounted on the top of the connecting plate, and a bottom end of the fourth electric push rod fixedly connected to the movable plate;

[0020] Through the above technical solution, the second hydraulic cylinder is used to drive the second hydraulic rod, which is suitable for continuous high-speed feeding operations. The maximum feeding speed can reach 100 times / minute. The fourth electric push rod drives the movable plate to move up and down to complete the clamping operation of the wires.

[0021] Furthermore, the wire pulling mechanism includes a flat plate fixedly connected to the top of the table, a third hydraulic cylinder is fixedly installed on the side of the flat plate, a third hydraulic rod is fixedly installed inside the third hydraulic cylinder, one end of the third hydraulic rod is fixedly connected to a concave plate, a fifth electric push rod is fixedly installed on the top of the concave plate, and there are two fifth electric push rods, and the bottom ends of the two fifth electric push rods are fixedly connected to the wire pulling plate;

[0022] Through the above technical solution, the third hydraulic cylinder is used to drive the third hydraulic rod as the main power source, which can easily meet the pulling needs of wires and cables of different specifications and materials. Whether it is a thinner electronic wire or a larger diameter and harder power cable, the mechanism can pull stably to meet the requirements of high-speed and continuous production operations. The maximum pulling speed can reach 80 meters per minute. The two fifth electric push rods control the movement of the wire pulling plate to achieve precise clamping and fine-tuning of the wires and cables.

[0023] Furthermore, the bottom of the table is fixedly connected to a supporting leg, and there are four supporting legs. The bottom ends of the four supporting legs are fixedly connected to rubber blocks, and the surfaces of the four supporting legs are fixedly connected to reinforcement rods. The tops of two of the reinforcement rods are overlapped with waste boxes, and handles are fixedly connected to both sides of the waste box. A wire storage cavity and a waste trough are opened on the top of the table, and a tin storage box is placed on the top of the table;

[0024] Through the above technical solution, the four supporting legs are distributed in a rectangular shape and fixed at the bottom of the table to form a stable supporting structure, which effectively disperses the pressure generated by the equipment during operation and ensures that the equipment remains balanced under high-speed operation or heavy-duty operation. The rubber blocks at the bottom of the supporting legs have good shock-absorbing properties, which can absorb the vibrations generated when the equipment is running, reduce the impact of vibrations on the accuracy of the equipment, and reduce noise to create a quieter working environment. The anti-slip design of the rubber blocks can increase the friction between the equipment and the ground, prevent the equipment from shifting during operation, and ensure the safety and stability of the equipment operation. The reinforcement rods fixedly connected to the surface of the supporting legs connect the four supporting legs to each other to form a stable frame structure. This design greatly enhances the overall rigidity of the support system and improves the deformation resistance of the equipment. Even when subjected to large lateral forces or uneven loads, the levelness and stability of the table can be maintained, providing support for various functional modules of the equipment. The waste bin is designed to be separated from the table so that the waste collection process does not affect the normal operation of the equipment. When the waste bin is full, it can be quickly removed and replaced without stopping the machine, thus ensuring the continuity of production. At the same time, this design also facilitates the classification and management of waste. Replacing different waste bins according to the type of waste (such as plastic sheaths, metal debris, etc.) is beneficial to the subsequent recycling and treatment of waste. The wire storage cavity on the top of the table provides a temporary storage space for wires and cables, which is convenient for operators to organize and access cables, avoid confusion caused by random placement of cables on the workbench, and improve work efficiency. The tin storage box is placed directly on the top of the table, close to the tinning mechanism, which is convenient for operators to add tin and reduce the time wasted due to frequent removal and placement of tin.

One end of a first rotating shaft 204 is fixedly connected to the output shaft of the stepper motor 202, and one end of the two first rotating shafts 204 is fixedly connected to a threaded rod 205. The surface of the threaded rod 205 is threadedly connected to a first fixing block 207.

The synchronous control accuracy of the double push rods can reach ±0.03mm, so that the cutting knife 703 always remains in a horizontal state, effectively improving the cutting section. Flatness and verticality, while the two electric push rods can be controlled independently or work together. In actual application, the synchronous action of the double push rods is realized through the PLC control system. At the same time, the stroke and thrust of the push rods can be adjusted according to the material and diameter of the wire. For example, for harder wires, the thrust of the push rod can be increased, and for thin-diameter wires, the stroke can be reduced to avoid over-cutting. The tinning mechanism 8 includes a servo motor 801 fixedly mounted on the side of the fixed base 5 through a mounting bracket.

The second hydraulic cylinder 901 is used to drive the second hydraulic rod 902, which is suitable for continuous high-speed feeding operations with a maximum feeding speed of 100 times / minute. The fourth electric push rod 905 drives the movable plate 906 to move up and down to complete the clamping operation of the wire. The wire pulling mechanism 10 includes a fixed connection On the flat plate 1001 on the top of the table 1, a third hydraulic cylinder 1002 is fixedly installed on the side of the flat plate 1001, and a third hydraulic rod 1003 is fixedly installed inside the third hydraulic cylinder 1002. One end of the third hydraulic rod 1003 is fixedly connected to a concave plate 1004, and a fifth electric push rod 1005 is fixedly installed on the top of the concave plate 1004. There are two fifth electric push rods 1005, and the bottom ends of the two fifth electric push rods 1005 are fixedly connected to a wire pulling plate 1006. The third hydraulic cylinder 1002 drives the third hydraulic rod 1003 as the main power source, which can easily meet the traction needs of wires and cables of different specifications and materials. No matter whether it is a thinner electronic wire or a power cable with a larger diameter and a harder texture, this mechanism can pull stably and meet the needs. To meet the requirements of high-speed and continuous production operations, the maximum wire pulling speed can reach 80 meters per minute. The two fifth electric push rods 1005 control the movement of the wire pulling plate 1006 to achieve precise clamping and fine-tuning of wires and cables. The bottom of the table 1 is fixedly connected with a support leg 12. There are four support legs 12. The bottom ends of the four support legs 12 are fixedly connected with rubber blocks 13. The surfaces of the four support legs 12 are fixedly connected with reinforcement rods 14. The tops of the two reinforcement rods 14 are overlapped with waste boxes 15. Both sides of the waste box 15 are fixedly connected with handles 16. A wire storage cavity 17 and a waste trough 19 are provided on the top of the table 1. A tin storage box 18 is placed on the top of the table 1. The four support legs 12 are distributed in a rectangular shape and fixed to the bottom of the table 1 to form a stable support structure, which effectively distributes The pressure generated by the equipment during operation is dispersed to ensure that the equipment maintains balance under high-speed operation or heavy-duty operation. The rubber block 13 at the bottom of the support leg 12 has good shock-absorbing performance, which can absorb the vibration generated by the equipment during operation, reduce the impact of vibration on the accuracy of the equipment, and reduce noise to create a quieter working environment. The anti-slip design of the rubber block 13 can increase the friction between the equipment and the ground, prevent the equipment from shifting during operation, and ensure the safety and stability of the equipment operation. The reinforcement rod 14 fixedly connected to the surface of the support leg 12 connects the four support legs 12 to each other to form a stable frame structure. This design greatly enhances the overall rigidity of the support system and improves the deformation resistance of the equipment, even when subjected to large lateral forces or uneven loads.It can also maintain the levelness and stability of the table 1, providing a solid foundation for the precise operation of each functional module of the equipment. The waste trough 19 opened on the top of the table 1 is located corresponding to the waste generation area of the equipment, so that the waste can fall smoothly into the trough through gravity or the action of the cleaning mechanism 11. The separate design of the waste box 15 and the table 1 ensures that the waste collection process does not affect the normal operation of the equipment. When the waste box 15 is full, it can be quickly removed and replaced without stopping the machine, ensuring the continuity of production. At the same time, this design also facilitates the classification and management of waste. Replacing different waste boxes 15 according to the type of waste (such as plastic outer shells, metal debris, etc.) is beneficial to the subsequent waste recycling and processing. The wire storage cavity 17 on the top of the table 1 provides a temporary storage space for wires and cables, which is convenient for operators to organize and access cables, avoid the confusion caused by the random placement of cables on the workbench, and improve work efficiency. The tin storage box 18 is placed directly on the top of the table 1, close to the tinning mechanism 8, which is convenient for operators to add tin and reduce the time wasted due to frequent tin removal.

[0048] Working principle: First, the PLC programmable controller starts the wire feeding device body 21 to convey the wires and cables to the wire groove 20 on the wire seat 3, then the PLC programmable controller starts the first hydraulic cylinder 402, and then the first hydraulic rod 403 drives the wire pressing plate 404 to fix the wires and cables, and then the PLC programmable controller starts the stepper motor 202, and then drives the first rotating shaft 204 and the threaded rod 205 to rotate, so that the first fixed block 207 and the second fixed block 208 drive the wire seat 3 to move to the terminal area, and then the PLC programmable controller starts the terminal body 6 to perform terminal treatment on the wires and cables. Terminal operation, after the terminal is completed, reverse the operation of the stepper motor 202 to return the wire seat 3 to its original position, then the PLC programmable controller starts the third hydraulic cylinder 1002, thereby moving the third hydraulic rod 1003 to the position of the wire and cable, and then the PLC programmable controller starts the fifth electric push rod 1005, thereby causing the wire pulling plate 1006 to clamp the wire and cable, and then reverse the operation of the third hydraulic cylinder 1002, causing the third hydraulic rod 1003 to pull the wire and cable to a suitable position, and then the PLC programmable controller controls the third electric push rod 809, thereby causing the wire clamping plate 8010 to clamp the wire and cable, Then, the PLC programmable controller starts the first electric push rod 702, which in turn causes the cutting knife 703 to cut the wires and cables on the cutting table 704. After the cutting is completed, the PLC programmable controller starts the servo motor 801, which in turn drives the second rotating shaft 803 to rotate, and moves the wire clamping plate 8010 to the tinning position. The third electric push rod 809 drives the wire clamping plate 8010 to clamp the end of the wire, and the second electric push rod 805 immerses the wire end into the tin storage box 18 for tinning. After the tinning is completed, the servo motor 801 drives the wire clamping plate 8010 to return to the initial position. After that, the PLC programmable controller starts the fourth electric push rod 905, thereby causing the movable plate 906 to clamp the wires and cables, and then the PLC programmable controller starts the second hydraulic cylinder 901, thereby causing the second hydraulic rod 902 to place the wires and cables into the wire storage cavity 17, and then the PLC programmable controller starts the drive motor 1108, thereby causing the third rotating shaft 1110 to drive the fan blades 1111 to rotate, generating airflow that is transported through the cover body 1103 and the pipe 1104 to the area where impurities are easily generated, and blows the debris and other impurities generated during the processing into the waste trough 19 and falls into the waste box 15. After the waste box 15 is full, the personnel can hold the handle 16 to replace the waste box 15;
