Description

Technical Field

[0001] The present application relates to the technical field of cable processing, and in particular to an automated pre-processing device for cables. Background Art

[0002] The data cable usually refers to a data transmission cable, such as a USB data cable, which generally includes a cable and connectors at both ends of the cable. When producing the aforementioned data cable, it is generally necessary to cut the rolled cable into a rated length, then electrically connect the core wire in the cable to the corresponding terminal in the connector by welding, and then assemble the connector to the electrical connection to finally produce the aforementioned data cable.

[0003] At present, when producing data cables, it is necessary to pre-process the ends of the cables first. Figure 1 As shown, a common cable structure generally includes a plurality of core wires 13, and an aluminum foil layer 14 arranged on the periphery of the core wires 13. The aluminum foil layer 14 is used to prevent electromagnetic interference and improve transmission efficiency. The aluminum foil layer 14 is coated with a braided layer 15 on the periphery. The braided layer 15 is used to improve the toughness of the product and prevent the aluminum foil layer 14 from falling off. The braided layer 15 is coated with an insulating layer 16 on the periphery. When processing the data cable, in order to expose the core wire 13 contained in the data cable, the aluminum foil layer 14, the braided layer 15, and the insulating layer 16 on the periphery of the core wire 13 must be stripped off before the subsequent connection operation between the core wire 13 and the connector can be carried out. This operation of stripping the outer layer of the core wire 13 is called the pre-treatment process of the data cable in the industry.

[0004] The pre-processing equipment generally includes a workbench, a cutting station and a stripping station arranged along the length of the workbench; the outer layer of the core wire is stripped off the core wire by the cutting equipment preset on the cutting station, and the outer layer structure of the core wire after cutting is stripped off the core wire by the stripping equipment preset on the stripping station.

[0005] In order to reduce damage to the core wire during the pre-processing process, the end of the data cable is generally pre-fixed and clamped in a preset carrier, and then the carrier is manually placed in the aforementioned cutting station and stripping station in turn to perform pre-processing operations on the cable end. After the pre-processing is completed, the data cable is taken out of the workbench. That is, in the entire pre-processing process, the amount of manual operation is large. For the processing of batch data cables, the above pre-processing method will lead to low production efficiency, so it needs to be improved. Summary of the invention

[0006] In order to optimize the pre-processing effect on cables and improve the efficiency of pre-processing operations, the present application provides an automated pre-processing device for cables.

[0007] The present application provides a cable automated pre-processing device, which adopts the following technical solution: A cable automated pre-processing device comprises a workbench, and a pre-processing unit arranged on one side of the workbench, wherein the pre-processing unit is used to perform pre-processing operations on the cables, and a conveyor belt is provided on the workbench, wherein the conveying direction of the conveyor belt is parallel to the length of the workbench; a first buffer area is provided at one end of the workbench, and a second buffer area is provided at the other end, wherein the first buffer area and the second buffer area are both used to place carriers, and the carriers are used to fix and clamp the cables; and further comprises a loading and unloading mechanism, wherein the loading and unloading mechanism is used to take out the carriers from the first buffer area and place them on the conveyor belt, and also to take the carriers on the conveyor belt and place them in the second buffer area.

[0008] By adopting the above technical solution, the first buffer area and the second buffer area are set up to place the carrier holding the cable, and then the loading and unloading mechanism is used to realize the transportation of the carrier in the first buffer area and the second buffer area, so that the aforementioned carrier loaded with cables that have not been pre-processed can be taken and placed on the conveyor belt, and the aforementioned carrier loaded with cables that have completed pre-processing can be taken out from the conveyor belt. In this process, the start and stop of the conveyor belt can be used to transport the carrier to the pre-processing unit, so that the pre-processing unit can pre-process the cables on the carrier. In summary, by setting the aforementioned loading and unloading mechanism and conveyor belt to realize the automatic transportation and loading and unloading of cables, the amount of manual participation in the pre-processing process is reduced, thereby achieving the effect of improving the pre-processing efficiency and realizing automated pre-processing operations.

[0009] Preferably, the conveyor belt comprises a first conveyor belt, which is arranged on the workbench and has a length direction parallel to the length direction of the workbench; the first buffer area is provided with a receiving frame, and the carriers are stacked and placed in the receiving frame along the height direction of the receiving frame, the receiving frame is open at the bottom, and the carriers located at the bottom of the receiving frame are located on the surface of the workbench and above the first conveyor belt; the loading and unloading mechanism comprises a unloading assembly and a plurality of groups of fetching rods; The material picking rod is arranged on the first conveyor belt, and all groups of material picking rods are arranged along the length direction of the first conveyor belt; the side wall of the carrier is provided with a docking port for inserting the material picking rod, and the docking port of the carrier at the bottom of the receiving frame is located on the moving path of the material picking rod when it moves with the first conveyor belt; the unloading assembly is used to make the material picking rod detach from the carrier docking port, and transfer the carrier on the first conveyor belt that is detached from the material picking rod to the second buffer area.

[0010] By adopting the above technical scheme, when the material picking rod arranged on the first conveyor belt moves with the transmission of the first conveyor belt, since the docking port of the carrier at the bottom of the first buffer area is located on the moving path of the material picking rod, when any group of material picking rods moves to the first buffer area, the material picking rod will be inserted into the docking port of the carrier at the bottom of the first buffer area, and during the movement, the carrier at the bottom of the first buffer area will be taken away from the first buffer area, and will be transmitted to the pre-processing unit for pre-processing operation with the movement of the first conveyor belt, and since the carriers in the first buffer area are stacked in sequence along the height direction of the first buffer area, the carriers can be moved downward in the height direction of the first buffer area by the weight of the carriers themselves, so that the carriers in the first buffer area can be moved in sequence to the open bottom of the first buffer area to wait for connection with the material picking rod; after the pre-processing operation is completed, the material picking rod can be separated from the docking port connected thereto by the unloading piece, and the carrier that has completed the pre-processing operation can be transmitted to the second buffer area, thereby realizing the full process transmission of the carrier loaded with cables in the entire pre-processing operation.

[0011] Preferably, when the carrier is detached from the receiving frame and connected with the material picking rod, there is a gap between the carrier and the first conveyor belt, and the conveyor belt also includes a second conveyor belt, one end of the second conveyor belt is located in the gap, and the other end of the second conveyor belt is located on one side of the second buffer area; the second buffer area is open at the top, and the second conveyor belt is used to transfer the carrier on the second conveyor belt to the second buffer area; the second conveyor belt is located at one end of the first conveyor belt close to the second buffer area, and the material picking rod is located on both sides of the second conveyor belt.

[0012] By adopting the above technical solution, a gap is defined between the carrier and the first conveyor belt. During the movement of the carrier along the length direction of the first conveyor belt, the carrier is supported by the material picking rod. A support plate may also be pre-arranged in the above gap so that the support plate can be used to cooperate with the material picking rod to support the carrier. When the carrier moves above the second conveyor belt, it is assumed that the cables on the carrier have completed the pre-processing operation. At this time, since the second conveyor belt is located at the end of the first conveyor belt, the moving path of the material picking rod along the end of the first conveyor belt is arc-shaped, so the material picking rod will be separated from the docking port during the movement. Correspondingly, after the carrier moves onto the second conveyor belt, the second conveyor belt can transport the carrier to the second buffer area located at the other end of the second conveyor belt, thereby realizing the mutual separation of the carrier and the material picking rod.

[0013] Preferably, the unloading assembly includes a unloading plate symmetrically arranged at the end of the second conveyor belt, and a movable part for driving the two symmetrically arranged unloading plates to move toward or away from each other, when the two unloading plates move away from each other, a dropping opening for the carrier to fall is formed between the unloading plates; a baffle is provided at one end of the unloading plate away from the second conveyor belt.

[0014] By adopting the above technical solution, the unloading plate is used to receive the carrier transmitted to the second buffer area by the second conveyor belt, and can use the baffle at the end of the unloading plate to enable the carrier that has detached from the second conveyor belt to be stably moved to the two symmetrically arranged unloading plates, and then the moving parts are used to drive the two unloading plates to move backwards, thereby opening the drop port, so that the carrier can fall from the drop port into the second buffer area under the action of its own weight.

[0015] Preferably, the moving part is arranged in a one-to-one correspondence with the unloading plate, and the moving part includes a docking rod, a gear set, a linkage rod and a reset member. The docking rod and the linkage rod are both slidably connected to one end of the first conveyor belt, and the docking rod is located on the moving path of the material picking rod as the second conveyor belt moves. The docking rod is used to slide when it is resisted by the material picking rod, and the gear set is used to drive the linkage rod to slide and resist the unloading plate when the docking rod slides due to the resistance of the material picking rod. The unloading plate is used to move and open the blanking port when it is resisted by the linkage rod; the reset member is used to drive the unloading plates to move toward each other and close the blanking port, and is also used to drive the linkage rod and the docking rod to move and reset.

[0016] By adopting the above technical solution, the two unloading plates are driven to move backwards by the movement of the material picking rod along with the movement of the first conveyor belt, thereby opening the drop opening and realizing the drop of materials from the carrier above the drop opening. This structure can reduce the addition of power sources and optimize the energy-saving effect.

[0017] Preferably, a positioning rod is provided in the second buffer area, and each of the unloading plates corresponds to at least one positioning rod. A notch is penetrated through the side wall of the unloading plate for inserting the positioning rod, and a positioning hole is penetrated through the side wall of the carrier for inserting the positioning rod; a positioning member is also included, and the positioning member is used to drive the positioning rod to rise and fall, so that the positioning rod passes through the notch and the positioning hole of the carrier on the unloading plate when rising.

[0018] By adopting the above technical solution, before the unloading plate is driven to move backward by the movable part, the positioning rod is driven to rise by the positioning part, so that the positioning rod sequentially passes through the notch and the positioning hole of the carrier on the unloading plate to realize the positioning of the carrier on the unloading plate, and then the unloading plate is driven to move backward by the movable part, so that the carrier passes through the blanking opening under the limiting action of the positioning rod, so that the carriers that pass through the blanking opening sequentially can be stacked more regularly in the second buffer area.

[0019] Preferably, a threaded sleeve is provided with a linkage screw rod at one end of the positioning rod away from the unloading plate, and the linkage screw rod is rotatably connected to the second buffer area, and the notch and the positioning hole are anti-rotation holes, which are used to prevent the positioning rod from rotating on its own; The picking rod is provided with a linkage gear, and the moving path of the picking rod moving with the first conveyor belt includes a first linkage path, a second linkage path and a third linkage path; the second linkage path is located between the first linkage path and the third linkage path, and when the picking rod moves into the second linkage path, the picking rod conflicts with the docking rod; The conveying speed of the second conveyor belt is much faster than that of the first conveyor belt. The positioning member includes an ascending gear and a descending gear rotatably connected to the workbench, and also includes a transmission component; the ascending gear is used to mesh and rotate with the linkage gear when the material picking rod moves into the first linkage path, and the descending gear is used to mesh and rotate with the linkage gear when the material picking rod moves into the third linkage path, and the transmission component is used to drive the linkage screw to rotate when the ascending gear or the descending gear rotates.

[0020] By adopting the above technical scheme, before the discharge plate moves backward, that is, before the material picking rod enters the second linkage path, it will first enter the first linkage path, and use the rising gear and the transmission component to drive the positioning rod to move upward, so that the positioning rod passes through the positioning hole of the carrier above the discharge plate. It should be noted here that the present application stipulates that the conveying speed of the second conveyor belt is much faster than that of the first conveyor belt. Therefore, the present application assumes that after the material picking rod and the carrier are separated from each other and before the material picking rod moves to the first linkage path, the carrier has been brought to the top of the discharge plate by the second conveyor belt; thereby positioning is achieved by the rising of the positioning rod; then the material picking rod continues to move into the second linkage path to drive the two discharge plates to move backward so that the carrier passes through the drop port, and when the material picking rod is out of the second linkage path, the two discharge plates can be driven to move toward each other by the reset member, so that the upper end of the positioning rod is reinserted into the notch, and then when the material picking rod moves to the third linkage path, the descending gear and the transmission component are used to drive the top end of the positioning rod to move downward and completely retract into the notch, so as to facilitate the subsequent movement of the carrier to the discharge plate.

[0021] Preferably, a winding frame is provided at one end of the workbench close to the first buffer area, on which wire is wound, and a conveying platform is provided between the winding frame and the first buffer area. A loading mechanism and a shearing assembly are provided on one side of the conveying platform. The loading mechanism is used to fix a carrier on the wire at specified intervals, and the shearing assembly is used to cut the wire between adjacent carriers on the conveying platform to which the wire is fixed.

[0022] By adopting the above technical solution, the wire is released onto the conveyor table through the winding frame, and the empty carrier is fixed on the carrier by using the loading mechanism, so that a carrier is fixed on the wire at every specified distance, and then the wire between adjacent carriers is cut by the shearing assembly, so that the wire is cut into a specified length, and the loading mechanism is used to realize the connection between each specified length of wire and the carrier.

[0023] Preferably, the carrier comprises a base plate and clamps symmetrically arranged on the base plate; an insertion space for the wire is formed between all the clamps, and a slope is provided at one end of each clamp close to the base plate, and a slope groove is provided on the surface of the base plate for each clamp to be inserted, and the inner wall of the slope groove is used to fit with the slope, and when the base plate moves in a direction close to the bottom of the slope groove, the insertion space is reduced; the loading mechanism comprises a punching cylinder, and a locking rod is also provided on each of the carriers. The clamps on the conveying table can be moved to the moving path of the driving end of the punching cylinder, and a locking hole is provided on the side wall of the clamp for the locking rod to be inserted, and the locking rod is connected to the inner wall of the slope groove by a spring, and the locking rod is used to be inserted into the locking hole under the action of the spring force.

[0024] By adopting the above technical solution, the wire is passed through the insertion space, and the carrier is moved to the bottom of the punching cylinder. The punching cylinder is moved downward to drive the two clamps to move toward the bottom of the inclined groove. During the movement, the inclined surface and the inclined groove cooperate with each other to narrow the insertion space, thereby achieving the clamping of the wire by the clamp. When the lower end of the clamp is inserted into the bottom of the inclined groove, the locking rod is inserted into the locking hole under the action of the spring force, thereby fixing the sliding position of the clamp, that is, maintaining the fixation of the wire by the clamp.

[0025] Preferably, the shearing assembly includes a cutter slidably connected to the side wall of the conveying table, a return spring connected between the cutter and the conveying table, and a linkage frame connected to the driving end of the punching cylinder; the linkage frame is used to press the cutter when the driving end of the punching cylinder is extended, so that the cutter slides and the return spring is deformed, and at this time the wire on the conveying table is located on the sliding path of the cutter.

[0026] By adopting the above technical solution, when the punching cylinder moves downward, it will drive the cutter to slide. Since the wire on the conveyor table is located on the sliding path of the cutter, the wire can be sheared by the sliding of the cutter. That is, the punching cylinder is used as a power source to realize the loading and fixing of the carrier and the wire, and the cutting of the wire by the cutter.

[0027] In summary, this application includes the following beneficial technical effects: By setting up a first buffer area and a second buffer area to place carriers holding cables, and then using a loading and unloading mechanism to transport the carriers in the first buffer area and the second buffer area, the carriers loaded with cables that have not been pre-processed can be placed on the conveyor belt, and the carriers loaded with cables that have completed pre-processing can be taken out from the conveyor belt. In this process, the start and stop of the conveyor belt can be used to transport the carrier to the pre-processing unit so that the cables on the carrier can be pre-processed by the pre-processing unit. In summary, by setting up the aforementioned loading and unloading mechanism and conveyor belt to realize the automatic transportation and loading and unloading of cables, the amount of manual participation in the pre-processing process is reduced, thereby achieving the effect of improving the pre-processing efficiency and realizing automated pre-processing operations.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 2-9 This application is described in further detail.

[0039] The present application embodiment discloses a cable automated pre-processing device. Figure 2 and Figure 3The cable automatic pre-processing equipment includes a winding rack 3, a conveying platform 1 and a workbench 2. The winding rack 3 is wound with wires to be processed. The conveying platform 1 and the workbench 2 are used to convey the wires released from the winding rack 3, and the conveying platform 1 and the workbench 2 are arranged in sequence along the wire conveying direction. A loading mechanism 11 and a shearing mechanism 12 are arranged in sequence on the conveying platform 1 and in a direction parallel to the wire conveying direction. The loading mechanism 11 is used to fix an empty carrier 4 on the wire at a specified distance after the wire is released from the winding rack 3. The shearing mechanism 12 is used to cut the wires between adjacent carriers 4 on the conveying platform 1 that have been loaded with wires.

[0040] On one side of the workbench 2, a first buffer area 21, a pre-processing unit 5 and a second buffer area 22 are sequentially arranged along the wire conveying direction. The first buffer area 21 is located at one end of the workbench 2 close to the conveying platform 1, and the second buffer area 22 is located at one end of the workbench 2 away from the conveying platform 1. The first buffer area 21 is used to cache the carrier 4 of the cut wire on the conveying platform 1, and the pre-processing unit 5 is used to perform pre-processing operations on the wire loaded on the carrier 4 in the first buffer area 21. The second buffer area 22 is used for storing the carrier 4 that has completed the pre-processing operation and the wire loaded therein; it also includes a loading and unloading mechanism 6, which is used to take the carrier 4 in the first buffer area 21 to the pre-processing unit 5 for the pre-processing unit 5 to perform pre-processing operations, and is also used to take the carrier 4 at the pre-processing unit 5 and place it in the second buffer area 22.

[0041] Reference Figure 3 and Figure 4 The winding frame 3 is provided with a motor for driving the winding frame 3 to rotate, so as to release the wire wound on the winding frame 3. The conveyor 1 and the workbench 2 are both provided with a conveyor belt 23 arranged along the wire conveying direction. The loading mechanism 11 includes a punching cylinder 111 and a plurality of groups of limiting rollers 112 rotatably connected to the conveyor 1, and a gap is reserved between each group of limiting rollers 112 for a single bundle of wire to pass through.

[0042] Reference Figure 4 and Figure 5The carrier 4 includes a bottom plate 42 and two clamps 43 symmetrically arranged on the bottom plate 42. The two clamps 43 enclose an insertion space 431 for a single bundle of wires passing through the gap. Each clamp 43 is provided with an inclined surface at one end near the bottom plate 42. The surface of the bottom plate 42 is provided with an inclined groove 421 for the end of the clamp 43 with the inclined surface to be inserted. The inner wall of the inclined groove 421 is used to fit with the inclined surface. The side wall of the bottom plate 42 near the bottom of each inclined groove 421 is also provided with a locking rod 44. The locking rod 44 is connected to the inner wall of the inclined groove 421 by a spring sliding movement. When the end of the clamp 43 is inserted into the bottom of the inclined groove 421, the locking rod 44 will be inserted into the preset locking hole on the side wall of the clamp 43 under the action of the spring elastic force, so as to fix the insertion position of the clamp 43. The driving end of the punching cylinder 111 is provided with a pressing plate for pressing down the clamping plate 43. When the driving end of the punching cylinder 111 extends out and presses down the two clamping plates 43 on the carrier 4 below it, the clamping plate 43 moves downward and moves toward the direction close to the bottom of the inclined groove 421. During the movement, the clamping plate 43 first squeezes the locking rod 44 into the inner wall of the inclined groove 421. Under the adaptation and fit between the inner wall and the inclined surface of the inclined groove 421, the two clamping plates 43 move toward each other during the downward movement and reduce the insertion space 431 so that the clamping plate 43 can clamp the wiring harness in the insertion space 431. After the clamping plate 43 moves down to the bottom of the inclined groove 421, the locking hole just moves to the moving direction of the locking rod 44, so that the locking rod 44 is inserted into the locking hole under the action of the spring to fix the clamping of the wiring harness by the clamping plate 43, thereby completing the loading of the wiring harness and the carrier 4.

[0043] Reference Figure 3 and Figure 4 The shearing mechanism 12 includes a cutter 121, a return spring 122 and a linkage frame 123. The cutter 121 is connected to the conveying platform 1 by the return spring 122. The driving end of the punching cylinder 111 is connected to the linkage frame 123. The other end of the linkage frame 123 is located above the cutter 121. When the linkage frame 123 moves downward with the extension of the driving end of the punching cylinder 111, the linkage frame 123 will press the cutter 121 and make the cutter 121 move downward. At this time, the return spring 122 is compressed, and the wire on the conveying platform 1 is located on the downward movement path of the cutter 121. The wire cutting process is achieved by the support of the conveyor belt 23 and the downward movement of the cutter 121; when the driving end of the punching cylinder 111 retracts and drives the linkage frame 123 to move upward, the linkage frame 123 releases the pressure on the cutter 121. At this time, the cutter 121 will move up and reset under the elastic force of the return spring 122.

[0044] Reference Figure 3 and Figure 6A receiving frame 211 with open ends at both the upper and lower ends is provided at the first buffer area 21. The lower end of the receiving frame 211 is fixed on the workbench 2. The upper end of the receiving frame 211 is slidably connected to two symmetrical receiving plates 213. The receiving plates 213 are used to open and close the upper opening of the receiving frame 211 during the sliding process. A sliding member 212 is provided at the upper end of the receiving frame 211 for driving the receiving plate 213 to slide. The sliding member 212 includes a photoelectric switch, a sliding component and a controller. The photoelectric switch is electrically connected to the controller for detecting The controller is used to detect whether there is a carrier 4 between the two receiving plates 213, and to obtain the detection signal of the photoelectric switch, and to control the opening and closing of the sliding component based on the detection signal. The sliding component is used to drive the receiving plate to move backward when starting, so that the receiving plate 213 opens the upper opening of the receiving frame 211 when moving backward, so that the carrier 4 between the two receiving plates 213 falls into the receiving frame 211, and the carriers 4 that fall into the receiving frame 211 successively are stacked and distributed in sequence along the height direction of the receiving frame 211. Among them, the sliding component can be a combination structure of a motor 515 and a bidirectional screw rod.

All groups of material picking rods 61 are spaced apart along the length direction of the first conveyor belt 231. Each group of material picking rods 61 includes 2 material picking rods 61, and are fixedly connected to the surfaces on both sides of the first conveyor belt 231.

[0046] Each side wall of the carrier 4 is provided with a docking port 411 for inserting the material picking rod 61. The docking port 411 of the carrier 4 at the bottom of the receiving frame 211 is located on the moving path of the material picking rod 61 when it moves with the first conveyor belt 231, so that when any group of material picking rods 61 moves to the bottom of the receiving frame 211, it drives the carrier 4 located at the bottom of the receiving frame 211 to move out of the receiving frame 211 along the transmission direction of the first conveyor belt 231.

At this time, the limit spring 414 further contracts. At this time, the rotation of the docking ring 514 can drive the base plate 42 and the clamping plate 43 and the wire on the base plate 42 to rotate, and then the laser head 512 is driven downward by the lifting cylinder 513, so that the laser head 512 can cut the wire circumferentially during the rotation of the wire, thereby realizing the cutting of the single-layer structure of the outer periphery of the core wire 13.

When the wire material and its carrier 4 after cutting and stripping are moved to one side of the tinning assembly 53 under the conveyance of the first conveyor belt 231, the core wire 13 at the end of the wire material will move to the upper surface of the sponge strip 534. At this time, the upper pressing plate 532 can be driven downward by the third driving member 535 to squeeze the sponge strip 534, so that the solder liquid squeezed out of the sponge strip 534 is adhered to the core wire 13, completing the tinning operation.

[0052] Reference Figure 2 , Figure 7 and Figure 8 , the conveyor belt 23 on the workbench 2 also includes a second conveyor belt 232, which is located at one end of the workbench 2 near the second buffer area 22, and the conveying direction of the second conveyor belt 232 is parallel to the conveying direction of the first conveyor belt 231. In the embodiment of the present application, for the carrier 4 on the workbench 2 connected to the material-collecting rod 61, there is a gap between it and the first conveyor belt 231, and one end of the second conveyor belt 232 is inserted into the gap, and the second buffer area 22 is located at the other end of the second conveyor belt 232, and is located on the extension line of the conveying direction of the second conveyor belt 232.

[0053] The loading and unloading mechanism 6 also includes a discharge assembly 62, which is used to separate the carrier 4 on the first conveyor belt 231 from the material-collecting rod 61, and stack it on the receiving platform 221 through the transmission of the second conveyor belt 232. Specifically, the discharge assembly 62 includes two discharge plates 621 symmetrically arranged at the ends of the second conveyor belt 232, and a moving member 7 used to drive the two discharge plates 621 to move toward or away from each other; the discharge plate 621 has an L-shaped cross-section, and a baffle 223 is provided on the side of the discharge plate 621 away from the second conveying platform 1, and the baffle 223 is fixed to the frame of the second conveyor belt 232. When the two discharge plates 621 are attached to each other, the discharge plates 621 are located above the receiving platform 221, and when the two discharge plates 621 are away from each other, a drop opening 224 is formed between the two discharge plates 621 for the carrier 4 to fall.

[0054] Reference Figure 5 , Figure 7 and Figure 8A positioning rod 222 is also provided on the receiving platform 221. The positioning rod 222 is arranged in the vertical direction, and each unloading plate 621 corresponds to a positioning rod 222. The top of the positioning rod 222 is inserted into a preset notch 6211 on the side wall of the corresponding unloading plate 621. A positioning hole 415 is also opened on the side wall of each carrier 4 for the positioning rod 222 to pass through and insert. A positioning member 8 is also provided on the receiving platform 221. The positioning member 8 is used to drive the positioning rod 222 to rise and fall, so that the top of the positioning rod 222 moves up, passes through the notch 6211, and is inserted into the positioning hole 415 of the carrier 4 moved to the unloading plate 621.

[0055] When the carrier 4 moves to the second conveyor belt 232 under the conveyance of the first conveyor belt 231, the second conveyor belt 232 continues to transport the carrier 4. The present application assumes that the conveying speed of the second conveyor belt 232 is much greater than the conveying speed of the first conveyor belt 231, thereby realizing the separation of the carrier 4 from the material picking rod 61. After the carrier 4 moves to above the unloading plate 621 driven by the second conveyor belt 232, the positioning rod 222 is driven upward by the positioning member 8 until the top of the positioning rod 222 is inserted into the positioning hole 415 of the carrier 4, and then the two unloading plates 621 are driven to move backwards by the moving member 7, so that the carrier 4 passes through the drop port 224 under the limiting action of the positioning rod 222 and falls onto the receiving platform 221, thereby realizing the regular stacking of the carrier 4 and the wires loaded thereon.

[0056] Reference Figure 7 , Figure 8 and Fig. 9 Specifically, the moving path of the material picking rod 61 moving with the first conveyor belt 231 includes the first linkage path 91, the second linkage path 92 and the third linkage path 93 which are arranged sequentially along the moving direction of the material picking rod 61. When the material picking rod 61 enters the first linkage path 91, the positioning rod 222 will move upward and pass through the positioning hole 415 of the carrier 4. When the material picking rod 61 enters the second linkage path 92, the two unloading plates 621 will move backwards to open the drop port 224; when the material picking rod 61 enters the third linkage path 93, the top of the positioning rod 222 will move downward and completely retract into the notch 6211.

[0057] The lower end of the positioning rod 222 is threadedly sleeved with a linkage screw rod 2222, and the linkage screw rod 2222 is rotatably connected to the receiving platform 221. The notch 6211 and the positioning hole 415 are both anti-rotation holes, which are used to prevent the positioning rod 222 from rotating during the up and down movement. Specifically, the positioning hole 415 and the notch 6211 of this embodiment are both square holes or rectangular holes. The material picking rod 61 is provided with a linkage gear 611, and the number of the linkage gears 611 on the material picking rod 61 can be multiple. The positioning member 8 includes an ascending gear 81, a descending gear 82 and a transmission component 83 that are arranged in a one-to-one correspondence with the linkage gear 611.

[0058] Each linkage gear 611 corresponds to an ascending gear 81 and a descending gear 82, and the transmission component 83 includes a rotating rod 831 rotatably connected to the workbench 2, a transmission sprocket 832 sleeved on each rotating rod 831, and a transmission chain 833 for transmission connection to all the transmission sprockets 832 on all the transmission rods 831 on the same side of the workbench 2; a docking sprocket 2221 rotatably connected to the positioning rod 222 and transmission connected to the transmission chain 833, and the docking sprocket 2221 is sleeved on the light rod part at the lower end of the linkage screw rod 2222, so as to drive the linkage screw rod 2222 to rotate when the docking sprocket 2221 rotates, thereby driving the positioning rod 222 to move up or down.

[0059] The moving member 7 is arranged in one-to-one correspondence with the discharge plate 621 . The moving member 7 includes a docking rod 71 , a gear set 72 , a linkage rod 73 and a reset member 74 . The reset member 74 includes a first spring 741 , a second spring 742 and a third spring 743 . The docking rod 71 is connected to the second linkage path 92 of the material picking rod 61 by sliding in the vertical direction through the first spring 741. The gear set 72 includes two racks and gears that are meshed with the two gears at the same time. One rack is connected to the docking rod 71, and the other rack is connected to the linkage rod 73. The gears are rotatably connected to the frame of the second conveyor belt 232. The linkage rod 73 is slidably connected to the bottom of the frame of the second conveyor belt 232 through the second spring 742. The unloading plate 621 is slidably connected to the side wall of the baffle 223 through the third spring 743. When the third spring 743 is not deformed, the preset arc surface on the lower surface of the unloading plate 621 is located on the sliding path of the linkage rod 73. When the first spring 741 is not deformed, the docking rod 71 is located on the moving path of the material picking rod 61 moving with the first conveyor belt 231. Specifically, when the picking rod 61 moves to the second linkage path 92 with the movement of the first conveyor belt 231, the picking rod 61 presses down the docking rod 71 during the movement, so that the docking rod 71 and the rack connected thereto drive the gear to rotate during the downward movement, and then the other rack and the linkage rod 73 move toward the direction close to the discharge plate 621 and press against the inclined surface 6212 on the lower surface of the discharge plate 621, so that the discharge plate 621 moves to open the blanking port 224. At this time, the third spring 743 is deformed. When the picking rod 61 rotates to release the abutment against the docking rod 71, the first spring 741 drives the docking rod 71 to move up and reset. The linkage rod 73 is acted upon by the second spring 742 and moves in the direction away from the discharge plate 621 to reset and release the abutment against the discharge plate 621. The discharge plate 621 moves to close the blanking port 224 under the drive of the third spring 743.

[0060] The implementation principle of an automated cable pre-processing device according to an embodiment of the present application is as follows: an empty carrier 4 is placed in the second gap 1131 on the conveying table 1, and the wire is allowed to pass through the insertion space 431; when the empty carrier 4 moves to below the punching cylinder 111, the punching cylinder 111 is used to move downward to drive the two clamps 43 of the carrier 4 to clamp and fix the wire, thereby completing the loading operation of the wire and the carrier 4; during this process, the wire between adjacent carriers 4 that have previously completed the loading operation is cut by the downward movement of the cutter 121; then the carrier 4 is moved to the receiving frame 211 under the conveyance of the conveying table 1, and the carrier 4 falls into the receiving frame 211 under the drive of the sliding component.

[0061] Whenever any group of material picking rods 61 on the first conveyor belt 231 moves to the bottom of the receiving frame 211 as the first conveyor belt 231 moves, the material picking rods 61 are inserted into the docking port 411 on the carrier 4 at the bottom of the receiving frame 211, and the carrier 4 is taken away from the receiving frame 211, and moved along the length direction of the workbench 2 to the pre-processing unit 5, and the pre-processing unit 5 is used to strip the current end to expose the core wire 13, and then solder liquid is adhered to the surface of the core wire 13, thereby completing the pre-processing operation.

[0062] The carrier 4 that has completed the pre-processing operation continues to move and moves to the second conveyor belt 232 to separate the carrier 4 from the material picking rod 61, and the carrier 4 will be conveyed to the unloading plate 621 by the second conveyor belt 232, and then move to the first linkage path 91, the second linkage path 92 and the third linkage path 93 in sequence with the material picking rod 61. During this process, the positioning rod 222 moves up to pass through the carrier 4 on the unloading plate 621, and then the unloading plate 621 moves backward to open the blanking port 224, so that the carrier 4 passes through the blanking port 224 under the positioning action of the positioning rod 222 and moves down to the receiving platform 221, and then the unloading plate 621 closes the blanking port 224 under the drive of the reset member 74, and the positioning rod 222 moves down and resets, finally completing the use of the movement of the carrier 4 to realize the automated pre-processing of the wire, reducing human participation and improving the efficiency of the pre-processing operation.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
