Description

Technical Field

[0001] The present invention relates to the technical field of offline crimping machines, and specifically to a fully automatic offline crimping machine. Background Art

[0002] A crimping machine is a necessary tool for wire connection crimping in the power industry during line infrastructure construction and line maintenance; it is mainly used to fix terminals to the ends of wires by crimping.

[0003] With the improvement of the automation level, offline crimping machines are becoming more and more automated. First, the incoming wire component controls one end of the wire to move directly below the first crimping component. After the first stripping component strips one end of the wire, the first crimping component crimps the first terminal onto one end of the wire. Subsequently, the incoming wire component controls the wire to drive the crimped first terminal to continue moving until the wire length is appropriate. Then, the first traction component pulls the other end of the wire cut by the cutting component to below the second crimping component. After the second stripping component strips the other end of the wire, the second crimping component crimps the second terminal onto the other end of the wire. Subsequently, the second traction component places the crimped wire on the tabletop.

[0004] In order to reduce the floor area of the offline crimping machine, the tabletop of the offline crimping machine is generally limited. Therefore, when the wire is relatively long, the other end of the wire will rest on the tabletop, and one end of the wire will hang down at the edge of the tabletop. As the number of wires placed on the tabletop increases, one end of the wire will have a certain pulling force on the other end of the wire under its own gravity, resulting in the wire being pulled off and falling from the edge of the tabletop. The fallen wires will scatter, which is not convenient for the staff to organize. At the same time, the wires and terminals that fall on the ground may even be damaged.

[0005] In view of this, in order to overcome the above technical problems, the present invention proposes a fully automatic offline crimping machine, which solves the above technical problems. Summary of the Invention

Detailed implementation manners

[0039] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0040] As Figures 1 to 9 shown, a fully automatic lower wire crimping machine described in the present invention includes:

[0041] Machine body 1; the machine body 1 is placed on the ground through the support feet 11;

[0042] Table top 2; the table top 2 is arranged at the upper end of the machine body 1;

[0043] The offline crimping body 3; the offline crimping body 3 is located at the side rear of the tabletop 2 and is used to crimp the terminal to the end of the wire; the offline crimping body 3 includes an incoming wire component, a first crimping component, a first wire stripping component, a cutting component, a first traction component, a second crimping component, a second wire stripping component and a second traction component. The connection relationship and positional relationship of each component of the offline crimping body 3 belong to the prior art and will not be elaborated here again;

[0044] The controller; the controller is used to control the automatic operation of the full-automatic offline wire crimping machine;

[0045] The full-automatic offline wire crimping machine further includes:

[0046] The clamping strip 4; the clamping strip 4 is horizontally located on the tabletop 2;

[0047] The card slot 41; the card slots 41 are evenly arranged at the upper end of the clamping strip 4; the width of the card slot 41 matches the diameter of the wire; the card slot 41 runs through the clamping strip 4 from front to back;

[0048] The motor 5; the motor 5 is fixedly connected to the tabletop 2; the motor 5 is located on one side of the clamping strip 4;

[0049] The pressing rope 51; the pressing rope 51 is fixedly connected to the output shaft of the motor 5; the pressing rope 51 can beat and press down the wire under the drive of the motor 5;

[0050] During operation, the tabletop 2 of the offline wire crimping machine is generally limited. Therefore, when the wire is relatively long, the other end of the wire will rest on the tabletop 2, and one end of the wire will hang down at the edge of the tabletop 2. As the number of wires placed on the tabletop 2 increases, one end of the wire will have a certain pulling force on the other end of the wire under its own gravity, so that the wire is pulled off and falls from the edge of the tabletop 2. The fallen multiple wires will be scattered, which is not convenient for the staff to organize. At the same time, the wires and terminals that fall on the ground may even be damaged;

[0051] Therefore, after the staff of the present invention check that the offline press is fault-free, the controller is started, and the offline press body 3 is controlled to work through the controller. The wire inlet assembly will control one end of the wire to be conveyed directly below the first crimping assembly. After the first wire stripping assembly strips one end of the wire, the first terminal is crimped to one end of the wire through the first crimping assembly. Subsequently, the wire inlet assembly controls the wire to drive the crimped first terminal to continue moving. After the wire length is appropriate, the first traction assembly pulls the other end of the wire cut by the cutting assembly to below the second crimping assembly. After the second wire stripping assembly strips the other end of the wire, the second terminal is crimped to the other end of the wire through the second crimping assembly. Subsequently, the second traction assembly places the crimped wire on the table 2. Subsequently, the crimped wire will fall on the upper end of the card strip 4. During the movement of the second traction assembly, the motor 5 will drive the pressing rope 51 to rotate. After the pressing rope 51 rotates, it will slap the wire falling on the card strip 4. The wire will have a downward force after being slapped, so that the wire will be snapped into the card slot 41 after being slapped. The diameter of the card slot 41 is equal to that of the wire, and the end of the wire has a terminal, so that even if the wire is pulled, the terminal of the wire will give the wire a limiting force, so that the wire can be stably stuck on the card strip 4. And the card slot 41 also has an inspection function, that is, in the case where the crimping strength of some terminals crimped at the end of the wire is insufficient, the terminal and the end of the wire are prone to looseness and detachment, and the wire will directly slide to the ground under the action of gravity, causing the separation of the terminal and the end of the wire. At the same time, when the terminal is not crimped at the end of the wire, the wire will directly slide to the ground under the action of gravity pulling, thus achieving the purpose of automatic inspection; after the card slot 41 is full of wires, the staff then hold the wire tightly and move it upward so that the wire is removed from the card slot 41. In order to avoid interference with the insertion of other wires into the card slot 41 during the process of the wire being removed from the card slot 41, the rotation of the motor 5 driving the pressing rope 51 can be selected to stop. After the wire is removed from the card slot 41, the motor 5 is started again to drive the pressing rope 51 to rotate again, and so on;

[0052] In the present invention, the motor 5 drives the pressing rope 51 to slap the crimped wire into the card slot 41 to achieve positioning and fixing, thereby avoiding the situation of the wire slipping off the table, and at the same time, it can also screen the unqualified crimped wires and automatically find out the defective products.

[0053] As an implementation manner of the present invention, a guiding strip 6 is provided at the upper end of the card strip 4; the guiding strip 6 is obliquely fixedly connected to the end of the card strip 4; the two guiding strips 6 are distributed in an inverted V shape;

[0054] During operation, after the crimped wire is pulled and dropped above the clamping strip 4, the wire falls between the two guiding strips 6 under the action of gravity. The guiding strips 6 will guide the wire, causing the wire to slide into the clamping strip 4 under the action of gravity. Subsequently, during the process of the pressing rope 51 patting the wire, the wire is discharged into the card slot 41. Even if the wire is not patted into the card slot 41 for the first time, the guiding strips 6 will intercept the wire, causing the wire to still be located between the two guiding strips 6. And after multiple pats, the wire is stably clamped into the card slot 41.

[0055] As an implementation manner of the present invention, a circular groove 42 is transversely arranged inside the clamping strip 4; the circular groove 42 is located below the card slot 41; a piston 43 is slidably and sealingly connected inside the circular groove 42; one end face of the piston 43 is rotatably connected to a screw rod 44; the screw rod 44 passes through the clamping strip 4 and extends to the outside; the screw rod 44 is threadedly connected to the clamping strip 4; strip-shaped grooves 45 are arranged on the opposite groove walls of the card slot 41; a strip block 46 is slidably and sealingly connected inside the strip-shaped groove 45; the inside of the strip-shaped groove 45 and the circular groove 42 are communicated through an air hole 47; the bottom of the strip-shaped groove 45 and the strip block 46 are connected by a tension spring 48; the circular groove 42 is filled with a medium, such as hydraulic oil; the screw rod 44 is arranged close to the motor 5;

[0056] During operation, before the offline press starts, first rotate the screw rod 44 forward. The screw rod 44 is threadedly connected to the clamping strip 4. During the rotation of the screw rod 44, the piston 43 will be driven to slide in the circular groove 42, causing the piston 43 to move in the direction close to the motor 5 under the control of the screw rod 44. Thus, the liquid pressure in the circular groove 42 is reduced. Subsequently, under the action of hydraulic transmission and in cooperation with the pulling action of the tension spring 48 on the strip block 46, the strip block 46 slides along the strip-shaped groove 45 close to the bottom of the strip-shaped groove 45, so that two corresponding strip blocks 46 move away from each other. Subsequently, the staff places the wire in the card slot 41, that is, the wire is located between the two strip blocks 46. Then rotate the screw rod 44 reversely. During the rotation of the screw rod 44, the piston 43 will be driven to move along the circular groove 42 away from the motor 5 direction, so that the liquid pressure in the circular groove 42 increases. Subsequently, under the action of hydraulic transmission, the strip block 46 is pushed to move against the tension of the tension spring 48, causing the strip block 46 to move along the strip-shaped groove 45 away from the bottom of the strip-shaped groove 45, so that two corresponding strip blocks 46 move closer to each other, and two corresponding strip blocks 46 are in contact with the wire. While ensuring that the wire can move smoothly in the card slot 41, the end of the wire can also be clamped and limited. This embodiment can be applicable to wires with different diameters and has a wide application range; the threaded gap between the screw rod 44 and the clamping strip 4 allows gas to flow through, ensuring that the piston 43 can move.

[0057] As an embodiment of the present invention, a slide groove 21 is provided at the upper end of the table 2; the slide groove 21 extends into the interior of the machine body 1; a guide rod 22 is inserted through and slidably connected to the bottom of the slide groove 21; the guide rod 22 is fixedly connected to the bottom of the clamping strip 4; a spring 23 is sleeved on the guide rod 22; the spring 23 is located between the bottom of the slide groove 21 and the clamping strip 4; the slide groove 21 covers the clamping strip 4 in a top view, so the downward movement of the clamping strip 4 will not cause interference;

[0058] During operation, when it is necessary to take the wire out of the slot 41, the clamping strip 4 is pressed. The clamping strip 4 is fixedly connected to the guide rod 22. Therefore, in the process of pressing the clamping strip 4, the guide rod 22 will be driven to penetrate and slide at the bottom of the slide slot 21, so that the clamping strip 4 moves downward and overcomes the elastic force of the spring 23, so that the clamping strip 4 drives the wire to move downward synchronously, and the wire is piled up under the obstruction of the table 2, and as the wire and the clamping strip 4 move relative to each other, the wire is moved out of the clamping slot 41, so the staff directly collects the wire moved out of the clamping slot 41 and takes it away. After the wire is taken away, the spring 23 gives the clamping strip 4 an upward force, so that the clamping strip 4 moves up and extends out of the table 2 under the push of the spring 23, and continues to clamp other crimped wires, and the clamping strip 4 moves downward to cooperate with the slide slot 21, so that it is convenient to move the wire out of the slot 41, which is convenient to use and saves the time of collecting the wire.

[0059] As an embodiment of the present invention, a rectangular groove 12 is provided on the front side of the body 1; the rectangular groove 12 is connected to the slide groove 21; a slide plate 13 is slidably connected in the rectangular groove 12; one end of the slide plate 13 extends out of the front side of the body 1, and the other end of the slide plate 13 is connected to the bottom of the clamping strip 4 through a connecting rod 14;

[0060] During operation, after a certain number of wires are gathered in the slot 41, the staff member steps on the slide plate 13 with his foot. After the slide plate 13 is stepped on, it will be subjected to a downward squeezing force, so that the slide plate 13 will slide along the rectangular slot 12. During the downward movement of the slide plate 13, the connecting rod 14 will be driven to move downward synchronously. After being driven, the connecting rod 14 will pull the card strip 4 downward. During the downward movement of the card strip 4, the spring 23 will be squeezed. The downward movement of the card strip 4 will cause the wire to detach from the slot 41. After the staff member takes away the wire that has detached from the slot 41, he releases the slide plate 13, so that the slide plate 13 does not have a downward squeezing force. Therefore, the spring 23 will push the card strip 4, the connecting rod 14, and the slide plate 13 to move upward synchronously, so that the card strip 4 returns to its original position. Through the arrangement of the slide plate 13 in this embodiment, the staff member does not need to press the card strip 4 with one hand and take away the wire with the other hand. Instead, the staff member only needs to step on the card strip 41 with his foot to achieve the wire detachment from the slot 41, which is more convenient for the staff member to use.

[0061] As an embodiment of the present invention, a first limiting groove 15 and a second limiting groove 16 are provided on the same groove wall of the rectangular groove 12; the first limiting groove 15 is located directly above the second limiting groove 16; the sliding plate 13 and the connecting rod 14 are connected by a torsion spring 17;

[0062] During operation, the torsion spring 17 will always give the sliding plate 13 a deflecting force. Therefore, when the staff steps on the sliding plate 13 and makes the sliding plate 13 move downward along the rectangular groove 12, the sliding plate 13 and the second limiting groove 16 are at the same horizontal position. Therefore, the sliding plate 13 will deflect under the action of the torsion spring 17 and snap into the second limiting groove 16. The staff releases the foot stepping on the sliding plate 13, so that the staff does not need to step on the sliding plate 13 all the time, and enables the staff to stay longer when holding the wire detached from the card slot 41, or even hide and stop using the card strip 4. When it is necessary to collect the wire by the card slot 41 in the card strip 4, just push the sliding plate 13 in the second limiting groove 16 away from the second limiting groove 16. The spring 23 will drive the card strip 4, the connecting rod 14 and the sliding plate 13 to return to their original positions. At this time, the sliding plate 13 and the first limiting groove 15 are at the same horizontal position. Therefore, the sliding plate 13 will deflect under the action of the torsion spring 17 and snap into the first limiting groove 15, thereby realizing the locking of the card strip 4, so that the card strip 4 will not shake or even move downward under the action of the impact force. If the card strip 4 is to be moved downward again, just push the sliding plate 13 out of the first limiting groove 15 with the foot and step down; this embodiment is more convenient to use.

[0063] As an embodiment of the present invention, inclined grooves 24 are provided on two opposite groove walls of the sliding groove 21; the inclined grooves 24 are inclined; the distance between the inclined grooves 24 and the card strip 4 increases as the card strip 4 moves downward; the two inclined grooves 24 jointly slidably connect a sliding rod 25; an L-shaped rod 26 is fixedly connected to the outer wall of the sliding rod 25; a slider 27 is slidably and sealingly connected in the circular groove 42; the side of the slider 27 away from the piston 43 is fixedly connected to one end of the L-shaped rod 26; the L-shaped rod 26 penetrates through the card strip 4 and is slidably connected to the card strip 4;

[0064] During operation, the downward movement of the card strip 4 will drive the slider 27, the L-shaped rod 26 and the slide bar 25 to move downward synchronously. The downward movement of the slide bar 25 will move away from the card strip 4 under the limiting action of the inclined groove 24. The slide bar 25 away from the card strip 4 will drive the L-shaped rod 26 to move away from the piston 43. The movement of the L-shaped rod 26 away from the piston 43 will drive the slider 27 to move along the circular groove 42, thereby increasing the distance between the slider 27 and the piston 43, reducing the liquid pressure between the piston 43 and the slider 27, and then under the action of hydraulic transmission and the pulling action of the tension spring 48 on the strip block 46, the strip block 46 slides along the strip groove 45 close to the bottom of the strip groove 45, thereby making the two corresponding strip blocks 46 move away from each other, making the wire more relaxed in the slot 41, thereby facilitating the wire to detach from the slot 41, reducing the friction between the wire and the slot 41, and avoiding damage to the wire surface due to friction and affecting the use; subsequently, during the downward movement of the card strip 4, the slider 27, the L-shaped rod 26 and the slide bar 25 will be driven to move upward synchronously, and the slide bar 25 will move closer to the card strip 4 under the limiting action of the inclined groove 24, and the slide bar 25 close to the card strip 4 will drive the L-shaped rod 26 and the slider 27 to move closer to the piston 43, so that the liquid pressure in the circular groove 42 returns to its original state when the distance between the piston 43 and the slide bar 27 becomes smaller; the sliding gap between the L-shaped rod 26 and the card strip 4 is for gas circulation.

[0065] As an embodiment of the present invention, the outer surface of the pressing and pulling rope 51 is provided with protrusions 52; the density of the protrusions 52 increases as they are away from the output shaft of the motor 5;

[0066] During operation, when the output shaft of the motor 5 drives the pressing rope 51 to rotate, the pressing rope 51 drives the protrusion 52 on the surface to move synchronously, and the friction between the pressing rope 51 and the surface of the wire is increased by the protrusion 52. The pressing rope 51 will first hit the wire, and will move relative to the wire as the motor 5 rotates, and the wire away from the motor 5 moves toward the motor 5 under the action of friction, so that the wire between the two guide bars 6 is spread out under the action of the pressing rope 51, thereby preventing the wire from being in the same slot 41. At the same time, in order to make the wires spread out more evenly, the wires close to the motor 5 are moved smaller, and the wires far away from the motor 5 are moved more, so that the wires are stuck in the slots 41 during the spreading process. In this embodiment, the wires are vibrated by knocking on the wires, and the connection strength between the terminals and the ends of the wires is further verified, so that the terminals with weak connection strength are detached from the ends of the wires under the action of vibration, and are screened in time to ensure the yield rate of the wires after crimping.

[0067] The specific workflow is as follows:

[0068] After the staff checks that the offline press is fault-free, the controller is started, and the offline press body 3 is controlled to work through the controller. The incoming line assembly will control one end of the wire to be conveyed directly below the first crimping assembly. After the first stripping assembly strips one end of the wire, the first terminal is crimped to one end of the wire through the first crimping assembly. Subsequently, the incoming line assembly controls the wire to drive the crimped first terminal to continue moving until the wire length is appropriate. Then, the first traction assembly pulls the other end of the wire cut by the cutting assembly to below the second crimping assembly. After the second stripping assembly strips the other end of the wire, the second terminal is crimped to the other end of the wire through the second crimping assembly. Subsequently, the second traction assembly places the crimped wire on the table 2. Then, the crimped wire will fall on the upper end of the card strip 4. During the movement of the second traction assembly, the motor 5 will drive the pressing rope 51 to rotate. After the pressing rope 51 rotates, it will slap the wire falling on the card strip 4. The wire will have a downward force after being slapped, so that the wire will be snapped into the card slot 41 after being slapped. The diameter of the card slot 41 is equal to that of the wire, and the end of the wire has a terminal, so that even if the wire is pulled, the terminal of the wire will give the wire a limiting force, so that the wire can be stably stuck on the card strip 4. Moreover, the card slot 41 also has an inspection function, that is, in the case where the crimping strength of some terminals crimped to the end of the wire is insufficient, the terminal and the end of the wire are likely to loosen and fall off, and the wire will directly slide to the ground under the action of gravity, causing the separation of the terminal and the end of the wire. At the same time, in the case where the terminal is not crimped to the end of the wire, the wire will directly slide to the ground under the action of gravity pulling, thereby achieving the purpose of automatic inspection; after the card slot 41 is full of wires, the staff then holds the wire tightly and moves it upward to make the wire move out of the card slot 41. In order to avoid interference with the insertion of other wires into the card slot 41 during the process of the wire moving out of the card slot 41, the motor 5 can be selected to stop driving the pressing rope 51 to rotate. After the wire moves out of the card slot 41, the motor 5 is started again to drive the pressing rope 51 to rotate again, and so on;

[0069] Among them, after the crimped wire is pulled and dropped above the clamping strip 4, the wire falls between the two guiding strips 6 under the action of gravity. The guiding strips 6 will guide the wire, so that the wire slides into the clamping strip 4 under the action of gravity. Subsequently, during the process of the pressing rope 51 patting the wire, the wire is discharged into the card slot 41. Even if it is not patted into the card slot 41 for the first time, the guiding strip 6 will intercept the wire, so that the wire still remains between the two guiding strips 6. And after multiple pats, the wire is stably clamped into the card slot 41. Before the offline press starts, first rotate the screw rod 44 in the positive direction. The screw rod 44 is threadedly connected to the clamping strip 4. During the rotation of the screw rod 44, the piston 43 will be driven to slide in the circular groove 42, so that the piston 43 moves close to the motor 5 under the control of the screw rod 44, thereby reducing the liquid pressure in the circular groove 42. Subsequently, under the action of hydraulic transmission and in cooperation with the pulling action of the tension spring 48 on the strip 46, the strip 46 slides along the strip-shaped groove 45 close to the bottom of the strip-shaped groove 45, so that the two corresponding strips 46 move away from each other. Subsequently, the staff places the wire in the card slot 41, that is, the wire is located between the two strips 46. Then rotate the screw rod 44 in the reverse direction. During the rotation of the screw rod 44, the piston 43 will be driven to move along the circular groove 42 away from the motor 5, thereby increasing the liquid pressure in the circular groove 42. Subsequently, under the action of hydraulic transmission, the strip 46 is pushed to move against the tension of the tension spring 48, so that the strip 46 moves along the strip-shaped groove 45 away from the bottom of the strip-shaped groove 45, and the two corresponding strips 46 move closer to each other, so that the two corresponding strips 46 are in contact with the wire. While ensuring that the wire can move smoothly in the card slot 41, the end of the wire can also be clamped and limited. During the process of removing the wire from the card slot 41, press the clamping strip 4. The clamping strip 4 is fixedly connected to the guide rod 22. Therefore, during the process of pressing the clamping strip 4, the guide rod 22 will be driven to penetrate and slide at the bottom of the sliding groove 21, so that the clamping strip 4 moves downward while overcoming the elastic force of the spring 23. Thus, the clamping strip 4 drives the wire to move downward synchronously. And due to the blocking effect of the table 2, the wire forms a pile. And as the wire and the clamping strip 4 move relative to each other, the wire moves out of the card slot 41. Therefore, the staff directly gathers and takes away the wire that has moved out of the card slot 41. After the wire is taken away, the spring 23 gives the clamping strip 4 an upward force, so that the clamping strip 4 moves upward under the push of the spring 23 and extends out of the table 2, and realizes the continuous clamping of other crimped wires.After a certain number of wires have accumulated in the card slot 41, the staff steps on the skateboard 13 with their foot. After being stepped on, the skateboard 13 will receive a downward extrusion force, causing the skateboard 13 to slide along the rectangular slot 12. During the downward movement of the skateboard 13, the connecting rod 14 will be driven to move downward synchronously. After being driven, the connecting rod 14 will pull the clamping strip 4 downward. During the downward movement of the clamping strip 4, the spring 23 will be compressed. The downward movement of the clamping strip 4 will cause the wires to disengage from the card slot 41. After the staff takes away the wires that have disengaged from the card slot 41, the skateboard 13 is released, so that the skateboard 13 no longer has a downward extrusion force. Therefore, the spring 23 will push the clamping strip 4, the connecting rod 14, and the skateboard 13 to move upward synchronously, thus causing the clamping strip 4 to return to its original position; the torsion spring 17 will always apply a deflecting force to the skateboard 13. Therefore, after the staff steps on the skateboard 13, causing the skateboard 13 to move downward along the rectangular slot 12, the skateboard 13 and the second limiting slot 16 are at the same horizontal position. Therefore, the skateboard 13 will deflect under the action of the torsion spring 17 and snap into the second limiting slot 16. The staff releases the foot stepping on the skateboard 13, so that the staff does not need to keep stepping on the skateboard 13, and enables the staff to have more time to take away the wires that have disengaged from the card slot 41, or even hide and stop using the clamping strip 4; when it is necessary to use the card slot 41 in the clamping strip 4 to collect wires, just push the skateboard 13 in the second limiting slot 16 away from the second limiting slot 16. The spring 23 will drive the clamping strip 4, the connecting rod 14, and the skateboard 13 to return to their original positions. At this time, the skateboard 13 and the first limiting slot 15 are at the same horizontal position. Therefore, the skateboard 13 will deflect under the action of the torsion spring 17 and snap into the first limiting slot 15, thus realizing the locking of the clamping strip 4, so that the clamping strip 4 will not shake or even move downward under the action of impact force. If the clamping strip 4 is to be moved downward again, just push the skateboard 13 out of the first limiting slot 15 with the foot and step down; during the downward movement of the clamping strip 4, the slider 27, the L-shaped rod 26, and the sliding rod 25 will be driven to move downward synchronously. The downward movement of the sliding rod 25 will move away from the clamping strip 4 under the limiting action of the inclined slot 24. The sliding rod 25 moving away from the clamping strip 4 will drive the L-shaped rod 26 to move away from the piston 43. During the movement of the L-shaped rod 26 away from the piston 43, the slider 27 will be driven to move along the circular slot 42, so that the distance between the slider 27 and the piston 43 becomes larger, causing the liquid pressure between the piston 43 and the slider 27 to decrease. Subsequently, under the action of hydraulic transmission and in cooperation with the pulling action of the tension spring 48 on the strip 46, the strip 46 will slide along the strip-shaped slot 45 close to the bottom of the strip-shaped slot 45, so that the two corresponding strips 46 move away from each other, making the wires looser in the card slot 41, thus facilitating the wires to disengage from the card slot 41, reducing the friction between the wires and the card slot 41, and avoiding damage to the wire surface due to friction, which may affect the use;Subsequently, during the downward movement of the clamping strip 4, the slider 27, the L-shaped rod 26, and the sliding rod 25 will be driven to move upward synchronously. The upward movement of the sliding rod 25 will cause it to approach the clamping strip 4 under the limiting action of the inclined groove 24. The sliding rod 25 approaching the clamping strip 4 will drive the L-shaped rod 26 and the slider 27 to move in the direction of the piston 43, causing the liquid pressure in the circular groove 42 to return to its original state when the distance between the piston 43 and the slider 27 becomes smaller; during the rotation of the output shaft of the motor 5 to drive the pressing rope 51, the pressing rope 51 will drive the protrusions 52 on its surface to move synchronously. The friction between the pressing rope 51 and the surface of the wire is increased by the protrusions 52. The pressing rope 51 will first strike the wire and will move relative to the wire as the motor 5 rotates, causing the wire away from the motor 5 to move in the direction of the motor 5 under the action of the friction force. As a result, the wire between the two guiding strips 6 is spread out under the action of the pressing rope 51, and the wire will be pressed again and snapped into the card slot 41.
