Description

Technical Field

[0001] This invention relates to the field of terminal manufacturing, and more particularly to a casing device and method for terminal manufacturing and processing. Background Technology

[0002] Terminals are connected to the outside of the equipment and are used as connection channels for communication or power supply between equipment. The terminal processing adopts the method of inserting ribbon cables into the housing, which is called inserting the housing. During the process, the ribbon cable is pulled and clamped and inserted into the housing clamped and fixed on the frame. Then the ribbon cable is cut to form a wired terminal. The other end of the ribbon cable is used to connect to the internal circuit of the equipment. Some terminal ribbon cables are fixed to the guide plate by soldering before being inserted into the housing.

[0003] Patent number CN110474220B discloses a single-head, one-time insertion machine for terminal wire production. The entire terminal wire processing process is highly continuous, and the production time for one terminal wire is approximately five seconds. This improves the production progress of terminal wires, shortens the processing cycle, reduces production costs, enhances practicality, and features a scientifically sound and reasonable structure that is safe and convenient to use.

[0004] Patent application CN110148871B discloses a method for inserting a ribbon cable into a housing, comprising a dividing step and a housing insertion step. In the dividing step, a ribbon cable dividing device separates the distance between the wires with metal terminals pressed onto the front of the ribbon cable into a spacing equal to the hole spacing of the housing socket, with the metal terminals at the front end of the ribbon cable exposed in front of the dividing device. Before the dividing device releases the wires at the front of the ribbon cable, a housing clamp clamps the front end of the ribbon cable laterally. After the housing clamp clamps the front end of the ribbon cable, the dividing device releases the wires at the front of the ribbon cable. The housing is fixed directly in front of the ribbon cable, and the housing clamp moves forward along the axial direction of the ribbon cable, inserting the metal terminals at the front end of the ribbon cable into the corresponding sockets of the housing. The ribbon cable insertion method of this invention has fewer steps and actions, and a simpler equipment structure.

[0005] However, during the cable insertion process, the cable routing mechanism needs to be replaced for different models of terminal housings to align the cable with the socket on the terminal housing. Summary of the Invention

[0006] The purpose of this invention is to provide a casing device and method for terminal manufacturing and processing, which enables wires to be inserted into the insertion holes of the terminal casing without changing the wire structure.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a casing device for terminal production and processing, including a wire insertion mechanism, wherein the wire insertion mechanism includes a slide plate slidably connected to a frame, the slide plate is connected to a fixed plate fixed on the frame via a cylinder, a plurality of wire tubes linearly arrayed along the length of the slide plate are connected to the slide plate via a rotating ball, the wire tubes pass through the slide plate and are connected to a rotating mechanism fixed on the side of the slide plate, the rotating ball rotates within an open ball sleeve fixed on the slide plate, a wire cutting mechanism is fixed on the wire tubes, and a casing clamping and feeding mechanism is fixed on the frame at the same level as the wire insertion mechanism;

[0008] The sliding plate in the insertion mechanism moves the wire tube relative to the housing clamping mechanism, allowing the wire to be inserted into the housing. The wire tube and the sliding plate are connected by a rotating ball, which allows the wire tube to rotate at any angle within a certain range, enabling wire insertion connections for different types of terminal housings.

[0009] Preferably, the conduit is threadedly connected to the rotating ball, and the rotating mechanism includes a sliding sleeve that is slidably connected to the portion of the conduit located between the sliding plate and the fixed plate. The sliding sleeve is rotatably connected to the first telescopic rod through the second telescopic rod, and a rod sleeve that is rotatably connected to the second telescopic rod is fixed on the sliding sleeve.

[0010] The conduit is connected to the rotating ball thread. After the conduit is rotated, its length is insufficient to align with the port of the casing. By rotating the conduit and the rotating ball relative to each other, the conduit can be moved relative to the slide plate, so that the end of the conduit is aligned with the insertion hole of the casing, ensuring the insertion is aligned.

[0011] Preferably, the first telescopic rods connected to the plurality of the conduits are spaced in connection, and the second telescopic rods connected to the conduits are spaced in connection;

[0012] Preferably, the conduits are divided into two groups, with any two of any three consecutive conduits forming a group, and the conduits in the same group being connected by a first telescopic rod and a second telescopic rod that are interconnected.

[0013] The method of alternating the first telescopic rod and the second conduit is used for casings with multiple layers of insertion holes, allowing the spaced-apart first and second telescopic rods to control the rotation of the same group of conduits.

[0014] Preferably, the portion of the guide tube located between the slide plate and the housing clamping mechanism is provided with a through groove, and a one-way fixing mechanism is provided at the through groove;

[0015] The conduit is equipped with an empty slot and connected to a one-way fixing mechanism, so that the wire can only move in one direction within the conduit. This allows the slide plate to move the wire during its movement and allows the wire to slide within the conduit when it returns.

[0016] Preferably, the one-way fixing mechanism includes a one-way stop wheel that is rotatably connected to the side bracket of the guide tube. The one-way stop wheel is provided with an inclined groove, and a clamping plate rotatably connected to the guide tube in the inclined groove makes one-way contact.

[0017] Preferably, the one-way drag wheel is rotatably connected to the bearing fixed in the middle of the bracket, and the clamping plate is rotatably connected to the bearing at the end of the bracket via a rotating shaft;

[0018] By using a method where a slanted groove is set on the unidirectional resist wheel to abut against the clamping plate, the unidirectional resist wheel that is pressed against the wire can only rotate in one direction.

[0019] Preferably, a wire cutting mechanism is provided on the side of the wire conduit near the fixed plate, and slots are provided on the upper and lower sides of the wire conduit. A blade holder is slidably connected to the outer side of the slots on the upper and lower sides of the wire conduit, and the blade holder is slidably connected to the upper blade and the lower blade.

[0020] Preferably, the upper and lower blades are each provided with a cutting edge and a peeling edge, a clamping block is fixed on the blade holder, and a one-way fixing mechanism is provided on the right side of the wire cutting mechanism.

[0021] The wire is cut by clamping the upper and lower blades together, so that the continuous wire can be separated after the wire is plugged into the shell. At the same time, the cutting blade can cut the wire with the insulation layer, so that the front end of the wire is exposed, which is convenient for connecting to the socket of the shell.

[0022] A method for inserting a casing into a terminal manufacturing and processing device is characterized by: inserting a wire through a fixed plate into a wire tube; the sliding plate relative to the frame drives the wire to be inserted into the casing; the wire tube is rotatably connected to the sliding plate; the wire tube can be rotated relative to the sliding plate according to the casing model, so that the end of the wire tube is aligned with the wiring port on the casing; the method can be adjusted arbitrarily within a certain range for different casing models without changing the wire structure.

[0023] The beneficial effects of this invention are:

[0024] 1. The wire is conveyed by connecting a rotating wire tube on a sliding plate. The angle of the wire tube end can be adjusted according to the plug type of the casing to align the wire tube with the casing. There is no need to change the wire conveying mechanism, making it highly applicable.

[0025] 2. A one-way fixing mechanism is installed on the guide tube so that the guide tube can clamp the wire during the movement of the sliding plate opposite to the housing clamping mechanism. When moving in the opposite direction, the wire enters the inside of the guide tube to complete the replenishment.

[0026] 3. The cutting tool is designed to use both a cutting edge and a sheath-cutting edge to simultaneously cut the wire, so that the wire is cut off after being inserted into the casing, and the insulation layer at the end of the wire is cut off, exposing the wire and facilitating the conduction between the wire and the conductive plate inside the casing.

Detailed Implementation

[0033] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0034] Example 1

[0035] like Figure 1-3As shown, the winding drum 7 is used to hold the wound wire. The unwinding method can be a conventional method. The wire passes through the wire hole 51 on the fixing plate 5 and is inserted into the wire tube 3. To reduce the friction between the wire and the fixing plate 5, the edge of the wire hole 51 is rounded to make its surface smooth. A one-way fixing mechanism 32 is set on the wire tube 3. When the wire tube 3 and its connected sliding plate 2 move to the left relative to the frame 1, the wire is fixed relative to the wire tube 3 under the one-way fixing mechanism 32. At this time, the wire tube 3 drives the wire to move towards the casing clamping mechanism 6. The casing clamping mechanism 6 uses a shaft seat fixed to the lower conveyor belt 62 on the frame 1, and is connected to the shaft seat of the upper conveyor belt 61 through a lifting cylinder 63. The upper conveyor belt 61 can be raised and lowered relative to the lower conveyor belt 62 to adjust its height, suitable for clamping casings of different thicknesses. The conveyor belt feeding method enables continuous feeding. The wire tube 3 is connected to the rotating ball 31 and is set inside the ball sleeve 21, so that the rotating ball 31 can rotate in any direction within a certain range relative to the ball sleeve 21. When the rotating ball 31 rotates, the wire tube 3 connected to the rotating ball 31 rotates accordingly. According to the sleeve model, the end of the wire tube 3 is aligned with the insertion hole 51 of the sleeve. When the slide plate 2 drives the wire tube 3 to move horizontally, the wire in the wire tube 3 can be accurately inserted into the insertion hole of the sleeve. In order to keep the distance between the ends of each wire tube 3 and the sleeve clamping mechanism 6 the same after the wire tube 3 rotates a certain angle, the wire tube 3 and the rotating ball 31 are set to be threaded connection. After the wire tube 3 rotates, the wire tube 3 and the rotating ball 31 can be rotated relative to each other according to the actual situation to ensure the accuracy of the wire insertion into the corresponding insertion hole in the sleeve.

[0036] The frame 1 is formed by connecting two bottom-suspended sliding rods through a fixing plate 5. The sliding plate 2, which is slidably connected to the frame 1, is fixed to the fixing plate 5 by a cylinder 4. The cylinder 4 is used to drive the sliding plate 2 to slide relative to the frame 1. The ball sleeve 21 on the sliding plate 2 can be a split type. For example, the sliding plate 2 can be set up with upper and lower parts fixed by bolts with the center of the ball sleeve 21 as the dividing line, so that the rotating ball 31 can be placed inside the ball sleeve 21 and fit against the inner side of the ball sleeve 21. The rotating ball 31 is a through-type structure. A sphere with a through hole the size of the outer diameter of the conduit 3, and an internal thread in the through hole that is threaded to the threaded section in the middle of the conduit 3. During manufacturing, the thread in the middle of the conduit 3 is first made, and then the guide tube is set with slots at the positions where the one-way fixing mechanism 32 and the cutting mechanism 34 are respectively connected at both ends of the thread. This facilitates the connection of the rotating ball 31 to the conduit 3, the sliding sleeve connected to the rotating mechanism 33 is fitted on the conduit 3, and then the one-way fixing mechanism 32 and the cutting mechanism 34 are fixed at the corresponding positions of the conduit 3.

[0037] Example 2

[0038] like Figure 1-3As shown, the fixed rod sleeve on the sliding sleeve is rotatably connected to the rotating rod at the end of the second telescopic rod, and the other end of the second telescopic rod is rotatably connected to the first telescopic rod. The first telescopic rod is fixedly connected to the side of the sliding plate 2. When the length of the first telescopic rod changes, since the first telescopic rod is inclined relative to the conduit 3, the change in the length of the first telescopic rod generates a vertical force on the conduit 3, causing the vertical angle of the conduit 3 to change. When the length of the second telescopic rod changes, the horizontal angle of the conduit 3 can be changed, thus achieving the purpose of arbitrarily changing the angle of the conduit 3 within a certain range.

[0039] During assembly, first connect the second telescopic rod to the sleeve on the sliding sleeve via a rotating rod, then fix the first telescopic rod to the slide plate 2. At the same time, connect the first telescopic rod and the second telescopic rod at intervals. The connection method depends on the terminal model of the required insert shell. If the terminal socket is double-layered, then each interval of the first telescopic rod will form a group, so that multiple wire tubes 3 can be connected to form two groups. If the terminal socket is triple-layered, then each interval of the first telescopic rod will form a group, so that it can be divided into three groups to accommodate different terminals entering the socket shell.

[0040] Example 3

[0041] like Figure 1-4 As shown, a through groove is formed on the conduit 3 for connecting the one-way fixing mechanism 32. A one-way stop wheel 322 is connected above the through groove via a support rod 321. An inclined groove 3221 is formed on the one-way stop wheel 322 in a circular array with the axis of the one-way stop wheel 322 as the center. One side of the inclined groove 3221 is an inclined surface with an acute angle to the diameter of the one-way stop wheel 322, and the other side is the surface where the diameter of the one-way stop wheel 322 is located. A clamping plate 323 is rotatably connected to the support rod 321 via a rotating shaft 324. The end of the clamping plate 323 slides relative to the inclined surface of the inclined groove 3221 and is parallel to the inside of the inclined groove 3221. The one-way roller 322 is in contact with the diameter of the one-way roller. When the wire enters the wire tube 3, the one-way roller exerts a certain pressure on the wire. During the movement of the wire, friction is generated on the one-way roller, causing the one-way roller 322 to rotate clockwise. At this time, the clamping plate 323 slides relative to the one-way roller 322. When the wire tube 3 moves to the left and the guide tends to move to the right relative to the wire tube 3, the clamping plate 323 clamps the inclined groove 3221, fixing the one-way roller 322. At this time, due to the pressure of the one-way roller 322, the winding shaft can be unwound, and the guide located between the slide plate 2 and the fixed plate 5 moves to the left.

[0042] Example 4

[0043] A slot is provided on the part of the conduit 3 between the slide plate 2 and the fixed plate 5, and a wire cutting mechanism 34 is connected to it. The wire cutting mechanism 34 includes an upper blade 341 and a lower blade 342 connected to the conduit 3 via a knife holder. The upper blade 341 and the lower blade 342 are slidably connected to the knife holder. A cylinder 4 is provided on the knife holder to drive the upper blade 341 and the lower blade 342 to move. The upper blade 341 and the lower blade 342 are respectively provided with a cutting blade 3423, a sheathing blade 3421 and a pressure block 3422. After the end of the wire is inserted into the casing, the cutting blade 3423 cuts the wire, and at the same time, the sheathing blade 3421 cuts a certain length of insulation layer at the cut point of the wire. The pressure block 3422 is used to fix the wire. After the wire cutting is completed, the upper blade 341 and the lower blade 342 are reset under the drive of the cylinder 4. The conduit 3 moves with the slide plate 2 to the side of the fixed plate 5, so that the stripped wire extends out of the left end of the conduit 3, which is convenient for insertion into the guide plate in the casing.
