Description

Technical Field

[0001] This invention belongs to the field of cable processing technology, and more specifically, relates to an automated production line for processing three-core wires. Background Technology

[0002] The cable needs to undergo a series of processes before the terminals can be crimped. Specifically, the outer sheath of the cable needs to be removed first, then the insulation paper needs to be removed to expose the inner core. Next, the spiral inner core needs to be straightened, then the outer sheath of the inner core needs to be removed to expose the copper wire. Finally, the terminals can be crimped onto the copper wire.

[0003] Three-core cables have three inner cores, making their processing more complicated. The three inner cores need to be separated and their positions adjusted to ensure they fit with the terminals. As a result, few existing cable manufacturers have production lines that can automate the processing of three-core cables. Summary of the Invention

[0075] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0076] The following disclosure provides many different implementations or examples for different ways of implementing the present invention.

[0077] Reference Figures 1 to 22As shown, in one embodiment of the present invention, a three-core wire automated processing production line includes a frame 1, a conveyor line 2 on the frame 1, and a plurality of clamps 21 on the conveyor line 2. The clamps 21 move along a first direction under the conveying of the conveyor line 2, and two adjacent clamps 21 respectively clamp the male end and the female end of the cable.

[0078] The frame 1 is arranged sequentially along the first direction, including a feeding station 3, two processing units, a male terminal crimping unit 11, and a female terminal crimping unit 12.

[0079] The feeding station 3 is used to place the male and female ends of the cable into the corresponding clamps 21 respectively; one processing unit strips and separates the male ends in the clamps 21, and another processing unit strips and separates the female ends in the clamps 21; the male end crimping unit 11 crimps the male ends in the clamps 21; the female end crimping unit 12 crimps the female ends in the clamps 21.

[0080] The processing unit includes a peeling station 4, a paper removal station 5, a wire sorting station 6, a camera recognition station 7, a three-core separation station 8, a three-core shaping station 9, and an inner core peeling station 10 arranged sequentially along the first direction.

[0081] The male and female ends of the three-core wire are clamped in two adjacent clamps 21. As the conveyor line 2 transports the wires, the male end is sequentially connected to each station of one of the processing units to complete the stripping and splitting of the male end of the three-core wire. Then, the male end crimping unit 11 is used to crimp the male end onto the male end of the three-core wire. The female end is sequentially connected to each station of another processing unit to complete the stripping and splitting of the female end of the three-core wire. Then, the female end crimping unit 12 is used to crimp the female end onto the female end of the three-core wire. In this way, a series of processes such as stripping, splitting, and crimping of the three-core wire can be completed automatically, improving processing efficiency.

[0082] In this embodiment, the direction perpendicular to both the first direction and the vertical direction is the second direction;

[0083] Reference Figures 2 to 3 As shown, the clamp 21 includes a fixed seat 211 fixed on the conveyor line 2, and the fixed seat 211 is provided with a through groove 212 extending in the second direction;

[0084] It also includes a cover 213, which is rotatably connected to a fixed base 211 via a rotating shaft 214. The axis of the rotating shaft 214 is parallel to the second direction. A coil spring 215 is provided on the rotating shaft 214. The cooperation between the cover 213 and the fixed base 211 is similar to a clamp structure. Half of the cover 213 can cover the through groove 212, and the other half of the cover 213 is suspended. By pressing the suspended position of the cover 213, the cover 213 can be rotated, thereby opening the through groove 212. When the cover 213 is not pressed, the coil spring 215 causes the cover 213 to return to its original position, and the cover 213 will cover the through groove 212. The cover 213 and the through groove 212 cooperate to clamp the cable.

[0085] Preferably, serrations can be arranged in the through groove 212 to increase the friction of the through groove 212, making it more stable when clamping the cable and preventing the cable from slipping.

[0086] More preferably, serrations can also be arranged at the position where the cover 213 mates with the through groove 212, making the cable clamping more secure.

[0087] In this embodiment, the conveyor line 2 is a chain plate conveyor belt, and the fixing seat 211 is fixed on the chain plate of the chain plate conveyor belt, so the clamp 21 can be recycled.

[0088] Reference Figures 4 to 5 As shown, the unloading station 3 includes two first pressure columns 31 arranged at intervals along the first direction. The two first pressure columns 31 correspond to two adjacent clamps 21. The first pressure columns 31 are raised and lowered under the drive of the first cylinder 32. When the first pressure column 31 presses the cover 213 of the corresponding clamp 21, the corresponding clamp 21 can be opened. The worker or robot can put the male end and female end of the cable into the through slot 212 of the corresponding clamp 21 respectively.

[0089] It also includes a first base 33, on which a second cylinder 34 is provided, and a cylinder plate 35 is fixed to the output end of the second cylinder 34; a positioning plate 36 is fixed to the cylinder plate 35, and two positioning sleeves 37 are arranged at intervals along the first direction on the positioning plate 36. A first gap 38 is provided between the positioning sleeves 37 and the cylinder plate 35. The cable passes through the positioning sleeves 37 and abuts against the cylinder plate 35. A sensor 39 is provided on the first base 33 for detecting whether there is a cable in the first gap 38.

[0090] The second cylinder 34 first drives the cylinder plate 35 to gradually approach the clamp 21, so that the positioning sleeve 37 is placed on the end of the cable. The end of the cable will press against the cylinder plate 35. As the cylinder plate 35 continues to move, it can slightly push the cable to move until the first gap 38 aligns with the sensor 39. The sensor 39 detects that there is a cable in the first gap 38, confirms that there is a cable in the clamp 21 and the length of the cable protruding from the clamp 21 meets the requirements. The first pressure column 31 rises and releases the cover 213, so that the clamp 21 can hold the cable. The cylinder plate 35 then moves away from the clamp 21, driving the positioning sleeve 37 to reset. The positioning sleeve 37 leaves the end of the cable to avoid affecting the movement of the cable. At this time, the sensor 39 will not align with the first gap 38 and will not perform detection.

[0091] In this embodiment, the clamp 21 holding the male end will be aligned with the corresponding processing unit, allowing the male end to be connected to each workstation in sequence; then the clamp 21 holding the female end will be aligned with the corresponding processing unit, allowing the female end to be connected to each workstation in sequence.

[0092] Reference Figure 6 As shown, the peeling station 4 includes a second base 41, on which a first slide 42 is slidably fitted. The first slide 42 moves along a second direction under the drive of a third cylinder 43.

[0093] The first slide 42 is provided with a vacuum suction tube 44 extending in the second direction. The end of the vacuum suction tube 44 near the clamp 21 is provided with a first cutting module 45. The side of the first cutting module 45 near the clamp 21 is provided with a clamping module 46.

[0094] The clamping module 46 includes a limiting block and a pressing block. The pressing block is raised and lowered under the drive of the clamping cylinder. Two positioning teeth are arranged at intervals along the first direction at the lower end of the pressing block. The limiting block is provided with tooth grooves that cooperate with the positioning teeth. When the clamp 21 is aligned with the stripping station 4, the cable will be located between the two tooth grooves. Then the clamping cylinder drives the pressing block to descend, allowing the positioning teeth to insert into the tooth grooves, clamping the cable and positioning it between the two positioning teeth to prevent the cable from deviating.

[0095] Next, the third cylinder 43 actuates, driving the first slide 42 to approach the clamp 21, so that the vacuum suction tube 44 is fitted onto the end of the cable, and the end of the cable is located in the vacuum suction tube 44.

[0096] Next, the first cutting module 45 is activated. The first cutting module 45 includes two first blades arranged vertically and a blade driving cylinder that drives the two first blades to move in opposite directions. The first blades are provided with V-shaped grooves. The V-shaped grooves on the two first blades are arranged opposite to each other. The two first blades move closer to each other so that the V-shaped grooves cut into the outer sheath of the cable.

[0097] Then, the third cylinder 43 is activated, driving the first slide 42 away from the clamp 21. At this time, the first blade moves along with it, stripping the outer sheath of the cable. The vacuum suction tube 44 is connected to the vacuum generator and has negative pressure adsorption capability, which sucks away the stripped outer sheath in time. The two first blades move away from each other and return to their initial positions. At this time, neither the vacuum suction tube 44 nor the first blade will interfere with the movement of the cable. The conveyor line 2 can move to the next station with the clamp 21.

[0098] Reference Figures 7 to 8 As shown, the dewaxing station 5 includes a third base 51, on which a second slide 52 is slidably fitted. The second slide 52 moves along a second direction under the drive of a fourth cylinder 53.

[0099] The second slide 52 is provided with a first rotating plate 54, which is rotatably mounted. The first rotating plate 54 rotates under the drive of the first motor 55, and the rotation axis of the first rotating plate 54 is parallel to the second direction.

[0100] The first rotating plate 54 is provided with a fifth cylinder 56 and two brush wheel modules 57. The fifth cylinder 56 drives the two brush wheel modules 57 to move in opposite directions in a direction perpendicular to the second direction. The brush wheel module 57 is provided with a clamping module 46 on the side near the clamp 21.

[0101] As described above, when the clamp 21 is aligned with the paper removal station 5, the clamping module 46 first clamps and positions the cable. Then, the fourth cylinder 53 actuates, driving the second slide 52 to approach the clamp 21, so that the part of the cable with the outer sheath removed is located between the two brush wheel modules 57. The brush wheel module 57 includes brush wheels and a brush wheel drive motor. The fifth cylinder 56 drives the two brush wheel modules 57 to approach each other, so that the brush wheels touch the paper sheath of the cable. As the brush wheels rotate, they can scratch the paper sheath. Then, the first motor 55 drives the first rotating plate 54 to rotate, thereby driving the brush wheel module 57 to rotate. The two brush wheels can rotate on their own axis and revolve around the central axis, scraping off the paper sheath.

[0102] Reference Figure 9 As shown, the cable management station 6 includes a fourth base 61, on which a third slide 62 is slidably fitted. The third slide 62 moves along a second direction under the drive of a second motor 63.

[0103] The third slide 62 is equipped with a three-jaw cylinder 64 and a third motor 65. The third motor 65 drives the three-jaw cylinder 64 to rotate. The side of the three-jaw cylinder 64 near the clamp 21 is equipped with a clamping module 46 for clamping the cable.

[0104] As described above, after the clamping module 46 is aligned with the cable handling station 6, the clamping module 46 first clamps and positions the cable. Then, the second motor 63 moves, bringing the third slide 62 closer to the clamping module 21, so that the part of the cable with the cardboard removed is positioned between the three jaws of the three-jaw cylinder 64. Subsequently, the three-jaw cylinder 64 operates, retracting the three jaws. The three jaws work together to gather the three inner cores of the cable, bringing the three inner cores together. Then, the third motor 65 operates, driving the three-jaw cylinder 64 to rotate, thereby rotating the gathered three inner cores, so that the section of the inner core with the outer sheath removed changes from a spiral state to a straight state, facilitating subsequent recognition by the camera recognition station 7.

[0105] Reference Figure 10 As shown, the camera recognition station 7 includes a second pressure column 71 and a fifth base 72. The second pressure column 71 is raised and lowered under the drive of the sixth cylinder 73 to open the clamp 21.

[0106] A second rotating plate 74 is rotatably mounted on the fifth base 72. The second rotating plate 74 rotates under the drive of the fourth motor 75, and the rotation axis of the second rotating plate 74 is parallel to the second direction.

[0107] The second rotating plate 74 is provided with a clamping module 76 for clamping the cable, and the fifth base 72 is provided with a camera recognition module 77 for recognizing the inner core of the cable.

[0108] When the clamp 21 aligns with the camera recognition station 7, the clamping module 76 activates first. The clamping module 76 includes two V-shaped blocks. Driven by the clamping cylinder, the two V-shaped blocks move in opposite directions and approach each other, clamping the cable. At this time, the part of the cable with its inner core exposed is located at the clamped position away from the clamp 21. Then, the second pressure column 71 descends, presses the cover 213, and opens the clamp 21. Simultaneously, the camera recognition module 77 takes a picture of the part of the cable with its inner core exposed to determine the position of each inner core. Next, the fourth motor 75 drives the second rotating plate 74 to rotate, which in turn rotates the clamping module 76, thereby rotating the cable so that the distribution of the inner cores matches the expected setting.

[0109] Reference Figures 11 to 13 As shown, the three-core separation station 8 includes a sixth base 81, on which a fourth slide table 82 is slidably fitted. The fourth slide table 82 moves along the second direction under the drive of the fifth motor 83.

[0110] The fourth slide 82 is provided with a first gripper 84, a second gripper 85 and a third gripper 86; the first gripper 84 can be raised and lowered under the drive of the seventh cylinder 87, and the seventh cylinder 87 can move along the first direction under the drive of the eighth cylinder 88; the second gripper 85 and the third gripper 86 move in opposite directions in the lower first direction under the drive of the ninth cylinder 89.

[0111] The first gripper 84 is provided with a clamping module 46 for clamping the cable at one end near the clamp 21;

[0112] As described above, after the clamp 21 is aligned with the three-core separation station 8, the clamping module 46 first clamps and positions the cable. Then, the fifth motor 83 drives the fourth slide 82 to move, and the fourth slide 82 gradually approaches the clamp 21, positioning the inner core between the two fingers of the first gripper 84. Then, the first gripper 84 moves first. The fingers of the first gripper 84 are provided with three arc-shaped notches that match the inner core. The three arc-shaped notches are arranged sequentially along the first direction. Therefore, after the first gripper 84 clamps the three inner cores, it can flatten the three inner cores, allowing them to be arranged side by side along the first direction. At this time, there is a gap between the position where the cable is clamped by the first gripper 84 and the position where it is clamped by the clamping module 46. With a certain gap, the second gripper 85 and the third gripper 86 use this gap to clamp the inner cores located on both sides respectively; then the first gripper 84 releases the inner core, and the ninth cylinder 89 actuates, causing the second gripper 85 and the third gripper 86 to move away from each other, allowing the inner cores on both sides to spread out; then the first gripper 84 clamps the inner core again, but since the inner cores on both sides have been spread out, the first gripper 84 can only clamp the middle inner core at this time, the seventh cylinder 87 actuates, pulling the first gripper 84 up and down to adjust the height of the middle inner core, and then the eighth cylinder 88 moves the seventh cylinder 87 along the first direction, thereby adjusting the position of the middle inner core in the first direction; based on this, the three inner cores are initially spread out.

[0113] Of course, in practice, the three-core separation station 8 can be adjusted according to the actual structure of the terminal. For example, the second gripper 85 and the third gripper 86 can also be raised and lowered to adjust the height of the other two inner cores.

[0114] Reference Figures 14 to 15 As shown, the three-core shaping station 9 includes a seventh base 91, on which a fifth slide 92 is slidably fitted. The fifth slide 92 moves along the second direction under the drive of the sixth motor 93.

[0115] The fifth slide 92 is provided with a lower shaping seat 94 and an upper shaping seat 95. The lower shaping seat 94 is raised and lowered under the drive of the tenth cylinder 96, and the upper shaping seat 95 is raised and lowered under the drive of the eleventh cylinder 97.

[0116] The lower shaping base 94 is provided with a clamping module 46 for clamping the cable on the side near the clamp 21;

[0117] As described above, after the clamping module 46 is aligned with the three-core shaping station 9 by the fixture 21, the clamping module 46 first clamps and positions the cable; then the sixth motor 93 drives the fifth slide 92 to move, and the fifth slide 92 gradually approaches the fixture 21, so that the inner core is located between the lower shaping seat 94 and the upper shaping seat 95. Then the tenth cylinder 96 and the eleventh cylinder 97 are activated, so that the lower shaping seat 94 and the upper shaping seat 95 move closer to each other. The top of the lower shaping seat 94 is provided with two protrusions, and the two protrusions are along the first The upper shaping seat 95 is arranged in a directional interval, dividing the top of the lower shaping seat 94 into three positioning areas. The upper shaping seat 95 is provided with a recess that matches the protrusion. The bottom surface of the upper shaping seat 95 is also provided with a positioning notch corresponding to the three positioning areas. When the lower shaping seat 94 and the upper shaping seat 95 are engaged, the protrusion will be inserted into the recess, and the positioning notch will press the inner core tightly onto the positioning area, further adjusting the position of the inner core and spreading the inner core so that the relative spacing of the inner core matches the terminal, which is convenient for subsequent engagement with the terminal.

[0118] Reference Figures 16 to 17 As shown, the core-peeling station 10 includes an eighth base 101, on which a sixth slide 102 is slidably fitted. The sixth slide 102 moves along the second direction under the drive of the seventh motor 103.

[0119] The sixth slide table 102 is provided with a second cutting module 104 for cutting the inner core skin, and a clamping module 46 for clamping the cable is provided on the side of the second cutting module 104 near the clamp 21.

[0120] As described above, after the clamp 21 is positioned at the inner core stripping station 10, the clamping module 46 first clamps and positions the cable. The second cutting module 104 includes two second cutters, each with three slots corresponding to the three inner cores. The two second cutters can move in opposite directions under the drive of the bidirectional screw assembly. The seventh motor 103 drives the sixth slide 102 to move, gradually bringing the sixth slide 102 closer to the clamp 21, so that the inner core is located between the two second cutters. Then, the bidirectional screw assembly moves, bringing the two second cutters closer to each other, and the three inner cores enter the corresponding slots. The two second cutters work together to cut the outer skin of the inner core. Subsequently, the sixth slide 102 gradually moves away from the clamp 21, and the second cutters move accordingly, removing the cut outer skin to expose the copper wires inside, which facilitates the subsequent terminal crimping process.

[0121] Preferably, an inner core pressing module can be provided between the pressing module 46 and the second cutting module 104. The pressing module 46 is generally pressed on the outer sheath of the cable, so it presses the entire cable and does not directly press the inner core. In order to facilitate the stripping of the inner core sheath, an additional module for pressing the inner core can be provided to press each inner core individually.

[0122] Reference Figures 18 to 21As shown, the frame 1 is provided with two copper wire winding stations 13. One copper wire winding station 13 winds copper wire at the male end of the fixture 21, and the other copper wire winding station 13 winds copper wire at the female end of the fixture 21.

[0123] The location of the copper wire winding station 13 can be arranged according to the actual situation, and it only needs to be arranged after the corresponding processing unit;

[0124] The copper wire winding station 13 includes a ninth base 131, on which a seventh slide 132 is slidably fitted. The seventh slide 132 moves along the second direction under the drive of the twelfth cylinder 133.

[0125] A vertical plate 134 is provided on the ninth base 131. Three clamps 135, corresponding to the three inner cores, are rotatably mounted on the vertical plate 134. The clamps 135 rotate under the drive of the eighth motor 136. A first clamping block 1351 and a second clamping block 1352 are hinged to one end of each clamp near the clamp 21. The first clamping block 1351 and the second clamping block 1352 are in an open position under the action of an elastic element. A thirteenth cylinder 1341 and a fourteenth cylinder 1342 are provided on the vertical plate 134. The thirteenth cylinder 1341... The output end of 41 is provided with an upper clamping plate 1343, which is located above the chuck 135. The upper clamping plate 1343 can be raised and lowered under the drive of the thirteenth cylinder 1341. The output end of the fourteenth cylinder 1342 is provided with a lower clamping plate 1344, which is located below the chuck 135. The lower clamping plate 1344 can be raised and lowered under the drive of the fourteenth cylinder 1342. The upper clamping plate 1343 and the lower clamping plate 1344 cooperate to allow the first clamping block 1351 and the second clamping block 1352 to be in a closed position.

[0126] A clamping module 46 for clamping cables is provided on the side of the chuck 135 near the clamp 21;

[0127] As described above, after the clamp 21 is aligned with the copper wire winding station 13, the clamping module 46 first clamps and positions the cable. At this time, the first clamping block 1351 and the second clamping block 1352 are in an open position. The twelfth cylinder 133 drives the seventh slide 132 to move, so that the seventh slide 132 gradually approaches the clamp 21, allowing the copper wire to enter between the corresponding first clamping block 1351 and the second clamping block 1352. Then, the thirteenth cylinder 1341 and the fourteenth cylinder 1342 are activated, and the upper closing plate 1343 and the lower closing plate 1344 cooperate to close the first clamping block 1351 and the second clamping block 1352, so that the first clamping block 1351 and the second clamping block 1352 are in a closed position, clamping and wrapping the copper wire. Then, the eighth motor 136 drives the chuck 135 to rotate, twisting the copper wire, so that the copper wire is wound into a spiral shape, and the copper wire will not burst open. When pressing the terminal later, the copper wire will not be exposed from the terminal.

[0128] Gears can be fixed on all three chucks 135, and the gears mesh with each other. A gear is also set at the output end of the eighth motor 136. Through gear transmission, the three chucks 135 can rotate synchronously.

[0129] Additionally, an inner core pressing module can be set between the clamp 135 and the pressing module 46. The pressing module 46 is generally pressed on the outer sheath of the cable, so it presses the entire cable and does not directly press the inner core. An additional module for pressing the inner core is set up to press each inner core individually, which makes it easier to rotate the corresponding copper wire.

[0130] Reference Figure 22 As shown, the male terminal crimping unit 11 and the female terminal crimping unit 12 are quite similar. The male terminal crimping unit 11 includes a riveting mechanism, a wire feeding mechanism, and a third crimping column. An external terminal feeding device delivers the terminal to the riveting mechanism. When the clamp 21 is aligned with the male terminal crimping unit 11, the third crimping column opens the clamp 21, and the wire feeding mechanism clamps the cable in the clamp 21 and moves the cable, allowing the copper wire to enter the riveting mechanism to cooperate with the terminal. Then, the riveting mechanism rivets the copper wire and the terminal together to complete the terminal crimping process. The female terminal crimping unit 12 is basically the same as the male terminal crimping unit 11. The difference is that, due to the different terminals, the mold used for riveting in the riveting mechanism is different.

[0131] After both the male and female ends of the cable are crimped, the cable will be transported to the unloading station by the conveyor line 2. The unloading station is equipped with a clamping column, which can open the two adjacent clamps 21, and the cable can be taken away by a person or a robot, thus completing the fully automated processing of the three-core cable.

[0132] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
