Description

Technical Field

[0001] The present invention relates to the technical field of terminal wire processing equipment, and particularly relates to a production device for male and female terminal wires with insulation protection. Background Art

[0002] A terminal wire is an electronic connection structure that connects a wire to a terminal. It can arbitrarily select the number of wires and the spacing, making the connection more convenient, greatly reducing the volume of electronic products, reducing production costs, and improving production efficiency. The electronic wire is widely used in the connection between various printer print heads and motherboards, signal transmission and board-to-board connection of plotters, scanners, copiers, audio systems, liquid crystal appliances, fax machines, various DVD players, etc. In modern electrical equipment, it is almost everywhere. When processing terminal wires, one end of the wire needs to be peeled, and then the exposed metal wire is pressed together with the metal terminal. Then, a plastic sleeve is sleeved at the connection position and the plastic sleeve is heat-shrunk and deformed by heat-sealing to tightly sleeve the connection position, thereby realizing the processing work of the terminal wire in sequence. And the method of heat-shrinking the plastic sleeve can also play a role in insulating and protecting the terminal wire. During this processing process, due to the need to provide insulation protection for the terminal wire, a large number of plastic sleeves are required. And the plastic sleeve is processed by cutting a plastic pipe. Therefore, it is also necessary to equip the plastic sleeve with many devices such as wire feeding equipment, cutting equipment, sleeving equipment, heating equipment, etc. The number of devices is large, which requires a large space, and its cost investment is large, and the terminal wire processing technology is relatively cumbersome.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0034] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. This embodiment is written in a progressive manner.

[0035] As Figures 1 to 5 shown, a production device for male and female terminal wires with insulation protection according to the present invention includes a slitting mechanism for slitting the epidermis at the end of a wire, a shaping mechanism for shaping the wire and the metal terminal, and a hot pressing mechanism for hot pressing and bonding the slit epidermis;

[0036] The shaping mechanism includes two arc-shaped buckles 1 distributed left and right. The two arc-shaped buckles 1 are on the same circle, and there is a processing gap between the side walls of the two arc-shaped buckles 1. The processing gap can provide space for the slitting mechanism and the hot pressing mechanism to process the wire epidermis. A plurality of pressing edges 2 are provided on the inner wall of the arc-shaped buckle 1, and the wire and the metal terminal can be press-fitted through the pressing edges 2;

[0037] The slitting mechanism includes two groups of cutter sets distributed up and down. Each group of cutter sets is composed of two slitting knives 3, and the cutting edges of the two slitting knives 3 are mutually attached. The cutter set is located at the position of the processing gap;

[0038] The hot pressing mechanism includes two electric heating plates 4 distributed up and down.

[0039] Specifically, the slitting mechanism can make two incisions on the upper and lower sides of the end of the wire, and the incisions are along the direction of the guiding axis, so that the skin at the end of the wire is slit into left and right pieces, and the two pieces of skin are separated. At this time, the metal wire inside the wire is exposed. The metal terminal is sleeved on the outside of the metal wire, the separated skin is released, and the shaping mechanism squeezes the two pieces of skin to approach and fit each other. At this time, the connection position of the metal terminal is inside the skin. The shaping mechanism squeezes and deforms the metal terminal through the skin, so that the metal terminal is tightly connected to the metal wire, and the skin protects the metal terminal and the metal wire inside it. Then, the heat pressing mechanism heats and softens the slit position of the two pieces of skin and makes them stick to each other, so that the slit skin is re-stuck into a whole. At this time, the connection position of the metal terminal and the metal wire is protected inside the skin, thus completing the processing of the terminal wire. Compared with the traditional processing method, this method not only saves the use of plastic sleeves, but also saves various equipment required for processing plastic sleeves, saves cost investment and the space occupied by equipment, and greatly simplifies the process steps.

[0040] During use, the two arc-shaped buckles 1 approach each other and are on the same circle. The cutter group and the electric heating plate 4 are both located outside the processing gap between the two arc-shaped buckles 1. The wire is inserted between the two arc-shaped buckles 1, and the skin of the wire to be processed is exposed in the processing gap. Since the metal terminal has not been inserted inside the skin at this time, the outer wall of the wire only maintains a contact and extrusion state with the pressing edge 2, and the deformation of the wire is small. At this time, the arc-shaped buckles 1 and the pressing edge 2 only serve to fasten the wire. When the inserted length of the wire reaches the specified value, the cutter group is used to slit the skin of the wire through the processing gap, and the two cutter groups work simultaneously, pushing the cutter group to slit the skin along the guiding length direction. After the skin is slit, the two slitting knives 3 in the cutter group separate from each other. At this time, the two slitting knives 3 push the slit skin to separate from the metal wire, so that the metal wire is exposed. At this time, the arc-shaped buckles 1 move synchronously with the slitting knives 3, the metal terminal is sleeved on the outside of the metal wire, the slitting knives 3 are pushed to separate from the skin, and the skin gradually returns to its initial state due to its own elasticity, pushing the two arc-shaped buckles 1 to approach each other and squeezing the skin, the connection position of the metal terminal inside the skin, and the metal wire inside the metal terminal through the pressing edge 2 inside the arc-shaped buckles 1, so that the metal terminal deforms and is tightly connected to the metal wire. At this time, the slit skins are butted against each other, and the two arc-shaped buckles 1 return to their initial positions, so that the electric heating plate 4 contacts the butting position of the skin through the processing gap between the two arc-shaped buckles 1, and the electric heating plate 4 performs heat sealing on the skin, so that the skin at the butting position is softened and stuck to each other. At this time, the skin is reconnected and the metal terminal is wrapped inside it, thus completing the processing of the terminal wire.

[0041] Since the cutting edges of the two slitting knives 3 in each cutting knife group fit together, the two slitting knives 3 can jointly cut a slit on the conductor skin. In actual production, in order to prevent the slitting knives 3 from cutting into the metal wire in the conductor, a small reserve amount is required for the slitting work of the conductor skin, so that the slitting knife 3 can be used to push the conductor skin to separate and directly tear the reserved skin, thereby achieving the separation of the conductor skin.

[0042] Preferably, Figure 6 As shown, the cutting edge of the slitting knife 3 is composed of an oblique cutting edge and a flat cutting edge. When the oblique cutting edge cuts the conductor skin, the flat cutting edge is still within the cut of the skin, so that the slitting knife 3 is offset and carries the skin away from the metal wire in the conductor.

[0043] Specifically, when the slitting knife 3 cuts the conductor skin, the beveled edge and the flat edge of the slitting knife 3 cut into the conductor. When the slitting knife 3 moves, the conductor skin can be cut with the help of the beveled edge. After the conductor skin is cut, the beveled edge moves outside the conductor, while the flat edge is still in the skin cut. At this time, the two slitting knives 3 in the slitting knife group are separated from each other, so that the slitting knife 3 moves the skin to be separated, so that the metal wire in the conductor is exposed, thereby achieving the purpose of the slitting knife 3 both cutting the conductor skin and peeling the conductor skin.

[0044] When the slitting knife 3 cuts into the conductor skin, the conductor needs to be cut with the help of the flat blade.

[0045] Preferably, Figure 6 As shown, the slitting mechanism also includes two side plates 5 distributed on the left and right sides, and the side walls of the side plates 5 facing the arc-shaped gusset plate 1 are provided with guide grooves 6 on the upper and lower sides, and the guide grooves 6 are U-shaped, and their openings face the direction away from the arc-shaped gusset plate 1, and both ends of the guide grooves 6 are inclined, and the inclination directions are opposite, and the slitting knife 3 can move along the direction of the guide grooves 6, thereby the slitting knife 3 can cut into or move out of the conductor skin by means of the inclined parts at both ends of the guide grooves 6;

[0046] A slide post 7 is slidably disposed in the guide groove 6 , and the slide post 7 is connected to the slitting knife 3 . The side plate 5 and the arc-shaped gusset plate 1 are fixedly connected via two connecting plates 8 .

[0047] Specifically, when the sliding column 7 moves within the inclined portion at one end of the guiding groove 6, its moving trajectory is also inclined. At this time, the sliding column 7 can drive the slitting knife 3 to gradually approach the wire skin and cut into the skin. When the sliding column 7 moves within the horizontal portion in the middle of the guiding groove 6, the slitting knife 3 normally cuts the wire skin. When the sliding column 7 approaches the inclined portion at the other end of the guiding groove 6, the slitting knife 3 completes the cutting of the wire skin. At this time, the flat blade portion of the slitting knife 3 is still within the cut of the wire skin. Push the two side plates 5 away from each other, and the side plates 5 drive the slitting knife 3 and the arc-shaped buckle 1 to move synchronously. The two slitting knives 3 within the cutter group are separated from each other, so as to strip the wire skin through the slitting knife 3 and expose the metal wires inside the wire.

[0048] When it is necessary to extrude and fasten the wire skin and the metal terminal, the sliding column 7 continues to move within the guiding groove 6 and moves into the inclined portion at the other end of the guiding groove 6. At this time, the slitting knife 3 is separated from the wire skin, and the slitting knife 3 is far away from the electric heating plate 4, so as to avoid the slitting knife 3 hindering the electric heating plate 4 from entering the processing gap.

[0049] Preferably, as Figure 6 shown, the slitting mechanism further includes a first threaded rod 9, a first motor 10, a first threaded sleeve 11, a long plate 12 and a sliding sleeve 13 that can provide power for the movement of the slitting knife 3. The first threaded rod 9 is rotatably installed between two connecting plates 8 on the side plate 5. The first motor 10 is installed on one connecting plate 8, and the first motor 10 is in transmission connection with the first threaded rod 9. The first threaded sleeve 11 is screwed on the first threaded rod 9 and can push the first threaded sleeve 11 to move by means of the rotation of the first threaded rod 9. Long plates 12 are fixed on both the upper and lower sides of the first threaded sleeve 11. A sliding sleeve 13 is slidably sleeved on the long plate 12. One side wall of the sliding sleeve 13 is fixedly connected to the sliding column 7, and the other side wall of the sliding sleeve 13 is fixedly connected to the slitting knife 3.

[0050] Specifically, the first motor 10 can push the first threaded sleeve 11 to move through the first threaded rod 9, so that the first threaded sleeve 11 pushes the slitting knife 3 and the sliding column 7 to move through the long plate 12 and the sliding sleeve 13. The slitting knife 3 can move along the trajectory of the guiding groove 6. Since the slitting knife 3 generates a position in the vertical direction when moving, the slitting knife 3 can carry the sliding sleeve 13 to slide on the sliding sleeve 13.

[0051] When the long plate 12 moves, the two sliding columns 7 on the side plate 5 can play a guiding and supporting role for the two long plates 12 and a first threaded sleeve 11.

[0052] Preferably, as Figure 5As shown, one end of the arc-shaped buckle plate 1 is set as the wire insertion end, and the other end of the arc-shaped buckle plate 1 is set as the positioning end. An arc-shaped positioning plate 14 for positioning the wire is provided on the inner wall of the positioning end of the arc-shaped buckle plate 1, and a closing edge is provided on the inner wall of the arc-shaped positioning plate 14.

[0053] Specifically, when the wire is inserted into the arc-shaped buckle plate 1 through the wire insertion end of the arc-shaped buckle plate 1, the end of the wire can contact the side wall of the arc-shaped positioning plate 14. At this time, the arc-shaped positioning plate 14 can position the position of the wire, so as to facilitate positioning the connection position of the wire and the cutting position of the wire skin. When the two arc-shaped buckle plates 1 approach each other again and squeeze and fasten the wire and the metal terminal, the arc-shaped positioning plate 14 can also contact the metal terminal and perform extrusion deformation treatment on it. With the closing edges in the two arc-shaped positioning plates 14, the metal terminal at the end of the wire can be shrunk and deformed, so as to realize the closing work of the metal terminal, and further strengthen the connection strength between the metal terminal and the wire.

[0054] Preferably, as Figure 3 shown, it further includes a clamping structure for fastening the wire during processing. The clamping structure includes two arc-shaped pressing plates 15 distributed left and right. The arc-shaped pressing plates 15 are located on one side of the wire insertion end of the arc-shaped buckle plate 1. The two arc-shaped pressing plates 15 can form a complete circle. A moving table 16 is fixed on the outer wall of the arc-shaped pressing plate 15. The moving table 16 is located outside the connecting plate 8. A plurality of guide rods 17 are slidably inserted through the moving table 16. The end of the guide rod 17 is fixedly connected to the outer wall of the side plate 5. Thus, the guide rod 17 can play a guiding role for the side plate 5, and a first cylinder 18 is arranged between the side plate 5 and the moving table 16 to provide a pushing and pulling force for the side plate 5 through the first cylinder 18.

[0055] Specifically, the two arc-shaped pressing plates 15 can fasten the wire, so as to facilitate fixing the guiding position during wire processing and prevent it from moving randomly. When the wire needs to be inserted, the two moving tables 16 are separated from each other, so as to drive the arc-shaped pressing plates 15 and the arc-shaped buckle plate 1 to separate synchronously, and it is convenient to insert the wire into the arc-shaped pressing plates 15 and the arc-shaped buckle plate 1.

[0056] When the two cutting knives 3 in the cutter group need to be separated from each other, the first cylinder 18 contracts, which directly drives the side plate 5 to move. The side plate 5 can drive the arc-shaped buckle plate 1 and the cutting knife 3 to move synchronously, and the guide rod 17 is for guiding the side plate 5.

[0057] Preferably, as Figure 4 shown, the hot pressing mechanism further includes a column 19 installed on the outer wall of each arc-shaped pressing plate 15. A crank arm 20 is rotatably provided at the end of the column 19 away from the arc-shaped pressing plate 15. The crank arm 20 is inclined in a curved shape, and the crank arm 20 is fixedly connected to the electric heating plate 4.

[0058] Specifically, the electric heating plate 4 can be supported by the upright post 19 and the curved arm 20. When it is necessary to thermally press the wire skin with the electric heating plate 4, only need to rotate the curved arm 20 to make the electric heating plate 4 contact with the wire skin through the processing gap between the two arc-shaped fasteners 1. Since the upright post 19 is fixed on the arc-shaped pressing plate 15 and the electric heating plate 4 is located outside the processing gap, it is necessary to connect the upright post 19 and the electric heating plate 4 by means of the curved-shaped curved arm 20.

[0059] Preferably, as Figure 7 shown, it further includes a transition mechanism. The transition mechanism is used to provide a pushing and pulling force for the curved arm 20 while meeting the movement requirement of the arc-shaped pressing plate 15. The transition mechanism includes two moving plates 21 distributed left and right. A long sleeve 22 is provided on the moving plate 21, and the positions of the two long sleeves 22 are opposite in the vertical direction. The long sleeve 22 on the moving plate 21 passes through the moving plate 21 and slides relatively. A long rod 23 is slidably arranged in the long sleeve 22. The end of the long rod 23 extends outside the long sleeve 22 and is fixedly connected to the other moving plate 21. A push-pull rod 24 is rotatably arranged obliquely on the outer wall of the long sleeve 22, and the push-pull rod 24 is rotatably connected to the curved arm 20.

[0060] Specifically, since the arc-shaped pressing plate 15 needs to move in the horizontal direction during wire threading, and the pushing and pulling force provided for the curved arm 20 is perpendicular to the moving direction of the arc-shaped pressing plate 15, it is necessary to set up a transition mechanism. When the arc-shaped pressing plate 15 moves horizontally, the arc-shaped pressing plate 15 can drive the long sleeve 22 to slide on the moving plate 21 through the upright post 19, the curved arm 20 and the push-pull rod 24. The long rod 23 slides relatively with the long sleeve 22. At this time, the position of the moving plate 21 is fixed. When it is necessary to adjust the position of the electric heating plate 4, the moving plate 21 can be directly pushed to move. The moving plate 21 can push the curved arm 20 to rotate on the upright post 19 through the long sleeve 22 and the push-pull rod 24, so as to push the electric heating plate 4 to flip and achieve the purpose of adjusting the position of the electric heating plate 4.

[0061] By arranging the long rod 23 on each long sleeve 22, the connection strength between the two moving plates 21 can be improved.

[0062] Preferably, as Figure 8 shown, it further includes an outer frame 25. The outer frame 25 is located outside the two moving platforms 16. A material conveying port 26 for the wire to pass through is opened in the middle of the outer frame 25. Two second cylinders 27 are provided on the outer frame 25, and the extending ends of the two second cylinders 27 are respectively fixedly connected to the two moving plates 21, thereby providing power for the moving plates 21 through the second cylinders 27;

[0063] The end of the guide rod 17 passes through the outer frame 25 and slides relatively. Power mechanisms are arranged on the upper and lower sides inside the outer frame 25. The power mechanisms are used to provide power for the horizontal movement of the two arc-shaped pressing plates 15.

[0064] Specifically, the outer frame 25 can support the moving platform 16 through the guide rod 17, so as to support the arc-shaped buckle plate 1 and the arc-shaped pressing plate 15. The second air cylinder 27 can provide a pushing and pulling force for the moving plate 21, so as to adjust the position of the electric heating plate 4, and the power mechanism is to provide power for the lateral movement of the two arc-shaped pressing plates 15.

[0065] Preferably, as Figure 8 shown, the power mechanism includes a second motor 28 fixed on the outer wall of the outer frame 25 and a transmission shaft 29 rotatably installed inside the outer frame 25. The second motor 28 is in transmission connection with the transmission shaft 29. The cross-section of the transmission shaft 29 is polygonal. Second threaded rods 30 are arranged on both the left and right sides of the transmission shaft 29. The transmission shaft 29 passes through the second threaded rods 30 and slides relative to them. A second threaded sleeve 31 is sleeved on the middle of the transmission shaft 29. The second threaded rods 30 are inserted into the second threaded sleeve 31 and are threadedly connected to each other. The thread directions on the left and right sides of the inner wall of the second threaded sleeve 31 are opposite. The second threaded sleeve 31 is fixedly connected to the outer frame 25 through a second fixing plate 33;

[0066] A first fixing plate 32 is arranged on the second threaded rod 30. The bottom of the first fixing plate 32 is fixed on the moving platform 16, and the second threaded rod 30 is rotatably connected to the first fixing plate 32.

[0067] Specifically, when the second motor 28 operates, it can drive the transmission shaft 29 to rotate. The transmission shaft 29 drives the two second threaded rods 30 to rotate synchronously. Since the second threaded rods 30 are threadedly connected to the second threaded sleeve 31, and the second threaded sleeve 31 is fixed on the outer frame 25 through the second fixing plate 33, the second threaded rods 30 can move on the second threaded sleeve 31, that is, the second threaded rods 30 can slide on the transmission shaft 29. And because the thread directions on the left and right sides of the inner wall of the second threaded sleeve 31 are opposite, the two second threaded rods 30 move synchronously and in opposite directions. The second threaded rods 30 can drive the moving platform 16 to move through the first fixing plate 32, so as to synchronously control the two arc-shaped pressing plates 15 to approach or move away from each other.

[0068] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
