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 two-core wires. Background Technology

[0002] Currently, power strips mainly consist of cables and junction boxes. During processing, the cables need to be stripped to remove the outer sheath at the cable ends. Then, terminals are pressed into the stripped areas, and the terminals are inserted into the junction box. The junction box generally consists of a lower box and an upper box. The lower box has a mounting slot and a first connecting post, into which the terminals are inserted. The upper box has a second connecting post that mates with the first connecting post. When the upper and lower boxes are closed, the first and second connecting posts are inserted together, completing the initial fixation. Both the lower and upper boxes have cable passages. The two cable passages are combined to allow the cables to pass through. The upper and lower boxes are then further fixed together using screws or ultrasonic welding.

[0003] Most existing manufacturers separate cable processing and boxing. The ends of the two core wires are separated manually, and the wires are stripped and crimped with terminals using equipment. The two core wires with crimped terminals are then collected and manually packed into boxes. The upper and lower boxes are then fixed together using equipment to complete the entire cable processing.

[0004] Due to the numerous processing steps, including those involving manual intervention, highly automated production lines are not yet available on the market. Summary of the Invention

[0106] 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.

[0107] Reference Figures 1 to 3 As shown, the processing of two-core wire a includes wire splitting, wire stripping, crimping terminals, terminal splitting, terminal conversion, and box assembly. Wire splitting involves separating the ends of the two cores of two-core wire a. Wire stripping involves removing the outer sheath of the separated core ends. Crimping terminals involves crimping terminals b onto the removed parts of the cores. Since the crimping is done as a whole, the two crimped terminals b are still stuck together. Terminal splitting involves separating the two terminals b. Terminal conversion involves adjusting the orientation of the terminals b to facilitate subsequent placement into the wire box.

[0108] The junction box includes a lower box body c and an upper box body d. The lower box body c has a mounting groove e, and terminal b is fixed in the mounting groove e. The lower box body c has a first connecting post, and the upper box body d has a second connecting post that mates with the first connecting post. When the upper box body d is closed to the lower box body c, the first and second connecting posts are inserted together, completing the initial fixation. Simultaneously, both the upper box body d and the lower box body c have wire passages f, which cooperate to allow two core wires a to pass through, ensuring that the two core wires a can be connected to terminal b. Furthermore, the lower box body c has a socket g corresponding to terminal b, which is sealed by a cover plate h. The lower box body c has a first ring, and the cover plate h has a second ring. The upper box body d has a pin, which is inserted into the first ring, and the second ring is fitted onto the pin, allowing the cover plate h to hang on the junction box. Then, the cover plate h is bent, allowing the plug i on the cover plate h to be inserted into the socket g, completing the sealing of the socket g.

[0109] Reference Figures 4 to 37 As shown, an automated two-core wire processing production line includes a frame 1, a first conveyor line 2 and a second conveyor line 3 on the frame 1, a clamp 4 for holding two core wires a on the first conveyor line 2, and a fixture 5 for assembling wire boxes on the second conveyor line 3.

[0110] The frame 1 is provided with a feeding unit 6, a wire separating unit 7, a wire stripping unit 8, a terminal crimping unit 9, a terminal separating unit 10, a terminal conversion unit 11, a lower box feeding unit 12, a terminal feeding unit 13, a cover feeding unit 14, a terminal crimping unit 15, an upper box feeding unit 16, an ultrasonic welding unit 17, and a unloading unit 18 arranged at intervals along the first direction.

[0111] The clamp 4 moves along the first direction under the conveying of the first conveyor line 2 and will sequentially connect to the feeding unit 6, the wire separating unit 7, the wire stripping unit 8, the terminal crimping unit 9 and the terminal separating unit 10 to complete the wire separating, wire stripping, terminal crimping and terminal separating processes of the two core wires a. The terminal transfer unit 11 will take over the two core wires a with the separated terminals b and complete the terminal transfer process.

[0112] The fixture 5 moves along the first direction under the conveying of the second conveyor line 3, and will sequentially connect to the lower box feeding unit 12, the terminal feeding unit 13, the cover feeding unit 14, the terminal clamping unit 15, the upper box feeding unit 16, the ultrasonic welding unit 17, and the unloading unit 18, so as to gradually assemble the wire box. During the assembly process, the two core wires a with the terminal b are put into the wire box using the terminal feeding unit 13, so that the terminal b is fixed in the wire box. In this way, the cable can be processed automatically, with a high degree of automation and improved production efficiency.

[0113] In this embodiment, the direction that is perpendicular to and horizontal to the first direction is the second direction.

[0114] Reference Figures 5 to 6 As shown, the clamp 4 includes a base 41 fixed on the first conveyor line 2. The base 41 is provided with a through groove 42 extending in the second direction. The two cores of the two core wires a can be arranged side by side in the through groove 42 in the first direction. The length direction of the two core wires a is exactly the second direction.

[0115] It also includes a cover 43, which is rotatably connected to the base 41 via a pivot 44. The axis of the pivot 44 is in the second direction, and a coil spring 45 is provided on the pivot 44 so that the cover 43 and the through groove 42 cooperate to clamp the two core wires a.

[0116] Specifically, the fit between the cover 43 and the base 41 is similar to a clamp structure. The middle part of the cover 43 is rotatably connected to the base 41. When there is no external force, only part of the cover 43 covers the through slot 42, and the other part of the cover 43 is suspended. At this time, if an external force presses on the suspended part of the cover 43, the cover 43 can be rotated to open the through slot 42 so that the two core wires a can be taken out.

[0117] In this embodiment, the first conveyor line 2 is a chain conveyor belt, which facilitates the installation of the base 41 on it.

[0118] Reference Figure 7As shown, the feeding unit 6 includes a first base 61, on which a first driving device 62 is provided. The output end of the first driving device 62 is provided with a first pressure column 63. The first pressure column 63 rises and falls under the drive of the first driving device 62. The feeding unit 6 is equivalent to a feeding station. After the fixture 4 is aligned with the feeding unit 6, the two core wires a need to be placed into the fixture 4. Therefore, the first pressure column 63 will descend and press down on the cover 43 to open the through slot 42. The two core wires a are placed into the through slot 42 by manual or robotic arm. At this time, the fixture 4 mainly clamps the middle position of the two core wires a, allowing the ends of the two core wires a to be exposed, which is convenient for subsequent processes.

[0119] The first base 61 is provided with a second driving device 64. The output end of the second driving device 64 is provided with a loading positioning plate 65. The second driving device 64 drives the loading positioning plate 65 to move along the second direction. Before placing the two core wires a into the fixture 4, the second driving device 64 first drives the loading positioning plate 65 away from the fixture 4, so that the distance between the fixture 4 and the loading positioning plate 65 is large. After placing the two core wires a into the fixture 4, the ends of the two core wires a will approach the loading positioning plate 65. The second driving device 64 then drives the loading positioning plate 65 to approach the fixture 4. During the movement of the loading positioning plate 65, it will touch and push the two core wires a to move. When the loading positioning plate 65 moves into place, the end position of the two core wires a is also positioned, ensuring that the splitting unit 7 described later can accurately process the ends of the two core wires a.

[0120] In this embodiment, the first driving device 62 is a telescopic cylinder, and the first pressing column 63 is connected to the output end of the telescopic cylinder. The end of the first pressing column 63 can be an arc-shaped end, which is convenient for pressing the cover 43 and can adapt to the tilt of the cover 43.

[0121] The second drive device 64 is also a telescopic cylinder, and the loading positioning plate 65 is fixed at the output end of the telescopic cylinder.

[0122] Reference Figures 8 to 9 As shown, the branching unit 7 includes a second base 71, a fixing block 72 is provided on the second base 71, and a sliding groove 721 is provided on the fixing block 72. The sliding groove 721 extends along the first direction and passes through the top and bottom.

[0123] Two locking blocks 73 are arranged sequentially in the slide 721 along the first direction. The locking blocks 73 move along the first direction under the drive of the third driving device 74. The upper end of the side of the locking block 73 near the other locking block 73 is provided with a receiving notch 731 that can accommodate the wire core.

[0124] The second base 71 is provided with a fourth drive device 75. The output end of the fourth drive device 75 is provided with a cutter 76. The cutter 76 is located above the slide 721 and between two locking blocks 73. The cutter 76 can be raised and lowered under the drive of the fourth drive device 75.

[0125] The second base 71 is provided with a fifth drive device 77, the output end of which is connected to the third drive device 74 to drive the block 73 to rise and fall.

[0126] During operation, before the fixture 4 aligns with the dividing unit 7, the fourth drive device 75 drives the cutter 76 to rise, placing the cutter 76 in a high position. The fifth drive device 77 drives the locking block 73 to descend, concealing the locking block 73 within the slide groove 721, ensuring that the upper end of the locking block 73 does not protrude from the slide groove 721. As the first conveyor line 2 transports the material, the fixture 4 aligns with the dividing unit 7, and the ends of the two core wires a move above the slide groove 721. At this point, the third drive device 74 drives the locking block 73 to move, bringing the two locking blocks 73 closer together until they reach a preset position. The two receiving notches 731 form a contour groove, and the fifth drive device 77 then drives the two locking blocks 73 to rise together. The ends of the two-core wire a are positioned in the contour groove. Then, the fourth drive device 75 drives the cutter 76 to descend. The cutter 76 aligns with the connection point of the two cores of the two-core wire a and separates the two cores. During this process, the third drive device 74 drives the locking block 73 to move, so that the two locking blocks 73 move away from each other. Therefore, the locking block 73 can both support the cores and cooperate with the separation of the cores. When the two cores are separated, the fourth drive device 75 drives the cutter 76 to rise, and the fifth drive device 77 drives the locking block 73 to descend. When the first conveyor line 2 sends away the clamp 4, the two-core wire a can be removed from the fixed block 72. Neither the cutter 76 nor the locking block 73 will interfere with the cores.

[0127] In this embodiment, the third drive device 74, the fourth drive device 75, and the fifth drive device 77 are all telescopic cylinders.

[0128] Preferably, two positioning claws 78 are provided above the fixing block 72. The two positioning claws 78 move under the drive of the sixth driving device 79, which is a cylinder. The positioning claws 78 and the cylinder can form a pneumatic claw structure so that the two positioning claws 78 move closer or further away from each other. The lower end of the positioning claw 78 near the clamp 4 is provided with a positioning notch 781. When the two positioning claws 78 move closer to each other, the two positioning notches 781 can form a positioning groove to press the two core wires a onto the fixing block 72 and position the two core wires a on the fixing block 72. This makes it easier for the cores of the two core wires a to cooperate with the receiving notch 731 on the clamping block 73. At the same time, both positioning claws 78 are provided with a clearance notch to avoid the cutter 76, ensuring that the cutter 76 can cut the two core wires a. When the cutter 76 separates the cores, the positioning cylinder 38 will drive the two positioning claws 78 to move away from each other, avoiding interference between the positioning claws 78 and the clamping block 73.

[0129] Reference Figure 10 and Figure 11As shown, the wire stripping unit 8 includes a third base 81, a seventh driving device 82 is provided on the third base 81, and a sliding plate 83 is provided at the output end of the seventh driving device 82 to drive the sliding plate 83 to move along the second direction.

[0130] Two blades 84 are arranged vertically above the sliding plate 83. An eighth driving device 85 is provided on the sliding plate 83. The two blades 84 move in opposite directions in the vertical direction under the drive of the eighth driving device 85. Two cutting grooves are provided at the end of the blade 84 closest to the other blade 84. The cutting grooves on the two blades 84 are used to cut the outer sheath of the wire core.

[0131] During operation, before the clamp 4 is aligned with the stripping unit 8, the seventh drive device 82 first drives the sliding plate 83 to move, so that the blade 84 is in a position close to the first conveyor line 2. The eighth drive device 85 drives the two blades 84 to move away from each other, so that the two blades 84 are open. When the clamp 4 is aligned with the stripping unit 8, the ends of the two core wires a will reach between the two blades 84. Then, the eighth drive device 85 drives the two blades 84 to move closer to each other. The cutting grooves of the blades 84 correspond one-to-one with the two core wires. The cutting grooves on the two blades 84 cooperate with each other to cut the outer sheath of the core wire. Then, the seventh drive device 82 drives the sliding plate 83 to move away from the first conveyor line 2, so that the blades 84 are away from the first conveyor line 2, and the cut outer sheath is peeled off, completing the stripping process.

[0132] A material trough can be installed on the third base 81 to receive the fallen skin, thereby collecting the skin and helping to keep the machine clean.

[0133] Preferably, the third base 81 is also provided with a limiting block 86, which is located between the blade 84 and the first conveyor line 2. A pressing block 87 is provided above the limiting block 86. The pressing block 87 is raised and lowered under the drive of the ninth driving device 88. Two positioning teeth 871 are arranged at intervals along the first direction at the lower end of the pressing block 87. The limiting block 86 is provided with a tooth groove 861 that cooperates with the positioning teeth 871. When the clamp 4 is attached to the stripping unit 8, the two core wires a will be located between the two tooth grooves 861. The ninth driving device 88 will drive the pressing block 87 to descend, so that the positioning teeth 871 are inserted into the tooth grooves 861, thereby positioning the two core wires a between the two positioning teeth 871 and preventing the two core wires a from deviating.

[0134] In this embodiment, the seventh driving device 82 is a ball screw assembly, which uses a motor to drive the screw to rotate, thereby driving the nut to move in the second direction. The sliding plate 83 is connected to the nut, thereby realizing the movement of the sliding plate 83.

[0135] The eighth drive device 85 is a bidirectional ball screw assembly, which drives the two blades 84 to move in opposite directions;

[0136] The ninth drive device 88 is a telescopic cylinder.

[0137] Reference Figures 12 to 15 As shown, the terminal pressing unit 9 includes a fourth base 91, on which a material placement block 92 that can be elastically lifted and lowered is provided. One end of the material placement block 92 along the first direction is connected to a terminal conveying module 93. The terminal conveying module 93 includes a material roll for winding the terminal chain and a pneumatic feeding device for pushing the terminal chain to move. The specific structure of the pneumatic feeding device can refer to the pneumatic feeding device in patent CN206379609U. The pneumatic feeding device moves intermittently, pushing two terminals b onto the material placement block 92 at a time.

[0138] The material placement block 92 is provided with a support tooth 94 on the side near the first conveyor line 2. The support tooth 94 is fixed on the fourth base 91. When the terminal b is located on the material placement block 92, the riveted part of the terminal b is suspended and aligned with the support tooth 94.

[0139] A stamping block 95 is provided above the material placement block 92, and a riveting block 96 is provided above the support tooth 94. The riveting block 96 is provided with a riveting groove 961 that is adapted to the support tooth 94. The stamping block 95 and the riveting block 96 are driven to rise and fall synchronously under the drive of the tenth drive device 97.

[0140] A clamping assembly 98 for clamping two core wires a is provided between the support tooth 94 and the first conveyor line 2. A slide table 981 is provided below the clamping assembly 98. The clamping assembly 98 is connected to the slide table 981. The slide table 981 moves along the second direction under the drive of the eleventh drive device 982. Furthermore, the clamping assembly 98 can be elastically raised and lowered on the slide table 981.

[0141] The fourth base 91 is provided with a twelfth drive device 99, and the output end of the twelfth drive device 99 is provided with a second pressure column 991. The second pressure column 991 rises and falls under the drive of the twelfth drive device 99.

[0142] During operation, when the clamp 4 presses the terminal unit 9, the twelfth drive device 99 drives the second pressure column 991 to descend and press down on the cover 43, opening the through slot 42. At the same time, the clamping assembly 98 clamps the two core wires a. The eleventh drive device 982 drives the slide table 981 to move away from the first conveyor line 2, moving the two core wires a so that the stripped part of the wire core moves into the riveting part of the terminal b. Then, the tenth drive device 97 drives the stamping block 95 and the riveting... As block 96 descends, pressing block 95 descends and presses onto material placement block 92, causing material placement block 92 to descend and knock terminal b off the terminal chain. The riveting part of terminal b is located in riveting groove 961. As riveting block 96 descends, riveting groove 961 engages with support tooth 94 to rivet the riveting part to the part of the wire core that has been stripped of its outer sheath. Since the two core wires a also descend during the stamping process, clamping assembly 98 can be raised and lowered flexibly, and can rise and fall together with the two core wires a to avoid pulling the wire core.

[0143] The output end of the tenth drive device 97 is equipped with a slider, which slides up and down on the fourth base 91. The stamping block 95 and the riveting block 96 are both fixed on the slider and move up and down with the slider. In addition, a pressing block 971 is also provided on the slider. The pressing block 971 slides up and down on the slider and uses an elastic element to allow the pressing block 971 to move up and down elastically. Therefore, when the slider descends and the stamping block 95 punches down the terminal b, the pressing block 971 will press down on the adjacent terminal b and use elastic force to press the terminal b. When the terminal b is punched down, the terminal chain will not be driven. When the stamping block 95 rises, the pressing block 971 will also rise, so that the terminal chain can continue to be fed to the placing block 92.

[0144] In this embodiment, the tenth driving device 97 is an eccentric wheel connecting rod slider mechanism. The eccentric wheel is driven to rotate by a motor, and the eccentric wheel then drives the connecting rod to move, and the connecting rod drives the slider to rise and fall.

[0145] The clamping assembly 98 includes two clamping blocks with slots on them. The two clamping blocks are driven to move by a pneumatic gripper. When the two clamping blocks move close to each other and into position, the two slots cooperate to form a clamping channel extending in the second direction, and the two core wires a are fixed in the clamping channel.

[0146] The eleventh drive device 982 is a telescopic cylinder, which is used to push the slide table 981 to move. The clamping assembly 98 is connected to the slide table 981 by a guide post, so that the clamping assembly 98 can be raised and lowered. A compression spring is sleeved on the guide post, and the compression spring is located between the slide table 981 and the clamping assembly 98 to realize the elastic raising and lowering of the clamping assembly 98.

[0147] The twelfth drive device 99 is a telescopic cylinder, which pushes the second pressure column 991 to rise and fall. The structure of the second pressure column 991 is the same as that of the first pressure column 63.

[0148] Reference Figure 16 As shown, the frame 1 is also equipped with a terminal unit 10. The clamp 4 that docks with the overpressed terminal unit 9 will dock with the terminal unit 10 under the conveying of the first conveyor line 2. Since two terminals b will be pressed onto the two core wires a at one time, the punching block 95 also punches off the terminals b in groups of two terminals b when punching off the terminals b. Therefore, the terminals b are also fixed in groups at the ends of the two core wires a. The terminals b on the two core wires a are still stuck together. The pressed terminals b must be separated before they can be used.

[0149] The terminal unit 10 includes a fifth base 101, on which a lower mold 102 is provided, and an upper mold 103 is provided above the lower mold 102. The upper mold 103 is raised and lowered under the drive of the thirteenth drive device 104. The upper mold 103 and the lower mold 102 are adapted to each other and can be used to place the terminals b. The upper mold 103 is provided with a dividing part that aligns the bonding points of the two terminals b. The lower mold 102 cooperates with the upper mold 103. Using the dividing part, the two terminals b riveted to the ends of the two core wires a are separated.

[0150] Meanwhile, the five base 101 is also provided with a fourteenth drive device 105. The output end of the fourteenth drive device 105 is provided with a third pressure column 106. The third pressure column 106 is raised and lowered under the drive of the fourteenth drive device 105. The third pressure column 106 can press down on the cover 43, so that the cover 43 opens the through slot 42, and releases the two core wires a, so that the subsequent terminal conversion unit 11 can take away the two core wires a with the terminal b separated.

[0151] In this embodiment, the thirteenth drive device 104 is similar to the tenth drive device 97, both being eccentric wheel connecting rod slider mechanisms, thereby driving the upper mold 103 to rise and fall.

[0152] The fourteenth drive device 105 is a telescopic cylinder, which is fixed on the fifth base 101, and the third pressure column 106 is located at the output end of the telescopic cylinder.

[0153] Reference Figures 17 to 20 As shown, the frame 1 is also provided with a terminal conversion unit 11. The terminal conversion unit 11 includes a sixth base 111. A first material transfer module 112 is provided between the sixth base 111 and the first conveyor line 2. The first material transfer module 112 moves the two core wires a of the separated terminal b in the terminal separation unit 10 to the terminal conversion unit 11. The sixth base 111 is provided with a sleeve mold 113 corresponding to the terminal b. The sixth base 111 moves along the second direction under the drive of the fifteenth drive device 114 so that the sleeve mold 113 is fitted onto the terminal b. The sleeve mold 113 can rotate under the drive of the sixteenth drive device 115.

[0154] Specifically, the sleeve mold 113 is rotatably mounted on the sixth base 111, and the outer wall of the sleeve mold 113 is provided with a sector gear 116. The sixteenth drive device 115 is fixed on the sixth base 111. The output end of the sixteenth drive device 115 is provided with a rectangular frame 117. The rectangular frame 117 is provided with racks 1171 on both sides along the first direction. The racks 1171 cooperate with the sector gear 116. The sixteenth drive device 115 drives the rectangular frame 117 to rise and fall, thereby rotating the sector gear 116 and driving the sleeve mold 113 to rotate.

[0155] The first material transfer module 112 includes a first transverse cylinder 1121. The output end of the first transverse cylinder 1121 is equipped with a first lifting cylinder 1122. The output end of the first lifting cylinder 1122 is equipped with a first material transfer plate 1123. A double-acting cylinder 1124 is mounted on the first material transfer plate 1123. The output end of the double-acting cylinder 1124 is equipped with a first pneumatic gripper 1125. The double-acting cylinder 1124 drives the two first pneumatic grippers 1125 to move closer or further apart. In use, the first lifting cylinder 1122 first drives the first material transfer plate 1123 to a low position, and the double-acting cylinder 1124 drives the two first pneumatic grippers 1125 to a position away from each other, allowing the two first pneumatic grippers to move further apart. The spacing of the grippers 1125 is sufficient to accommodate two core wires a. Then, the first transverse cylinder 1121 moves the first transfer plate 1123 into the terminal unit 10. The first lifting cylinder 1122 then drives the first transfer plate 1123 to rise to a high position, so that the first transfer plate 1123 is located between the fixture 4 and the lower mold 102. The bifurcation of the ends of the two core wires a is located between the two first pneumatic grippers 1125. Then, the double-acting cylinder 1124 drives the two first pneumatic grippers 1125 to move closer to each other, so that the first pneumatic grippers 1125 hold the core wires at the bifurcation of the ends of the two core wires a. Then, the first transverse cylinder 1121 resets and brings the two core wires a to the position opposite to the rectangular frame 117.

[0156] Then, the first lifting cylinder 1122 lowers the first transfer plate 1123, aligning terminal b with the sleeve mold 113. The sleeve mold 113 is custom-made and has a flat groove that fits the terminal b. The fifteenth drive device 114 drives the sixth base 111 to move, so that the sleeve mold 113 fits onto the terminal b. Then, the sixteenth drive device 115 drives the sleeve mold 113 to rotate, changing the posture of the terminal b.

[0157] In this embodiment, both the fifteenth drive device 114 and the sixteenth drive device 115 are telescopic cylinders.

[0158] It should be noted that since the wire core is held by the first pneumatic gripper 1125, the wire core is also twisted when the terminal b is rotated. If the sleeve mold 113 is removed at this time, the terminal b may return to its original position and cannot maintain the rotated posture, which is not conducive to the subsequent clamping of the terminal b by the terminal feeding unit 13.

[0159] Therefore, a second lifting cylinder 118 is provided between the first transfer plate 1123 and the rectangular frame 117. The output end of the second lifting cylinder 118 is provided with a wire core positioning plate 1181 and a second pneumatic gripper 1182. The top of the wire core positioning plate 1181 is provided with wire core receiving grooves 53 at both ends along the first direction. Each of the two fingers of the second pneumatic gripper 1182 is provided with a sealing plate 1183. When the two sealing plates 1183 approach each other, they will cooperate with the wire core positioning plate 1181 to close the wire core receiving grooves 53. When the sleeve mold 113 rotates the terminal b, the first pneumatic gripper 1182 is released. 125 and make the two first pneumatic grippers 1125 move away from each other. The second lifting cylinder 118 drives the wire core positioning plate 1181 and the second pneumatic gripper 1182 to rise. The wire cores at the bifurcation of the two wire cores a are just located in the two wire core receiving grooves 53. Then the second pneumatic gripper 1182 drives the two blocking plates 1183 to move closer to each other, so that the blocking plates 1183 close the wire core receiving grooves 53 and press the wire cores into the wire core receiving grooves 53. At this time, let the sleeve mold 113 leave the terminal b. The terminal b will not return to its original position, which is convenient for the subsequent terminal feeding unit 13 to clamp the terminal b.

[0160] Reference Figures 21 to 23 As shown, the fixture 5 includes a base plate 51 and a pressing module 52 disposed on the base plate 51. A receiving groove 53 is disposed on the base plate 51. The receiving groove 53 generally extends along the second direction. The lower box body c is placed into the receiving groove 53. When the two core wires a with terminals b are inserted, the length direction of the two core wires a is also the second direction. The two core wires a passing through the lower box body c are located at one end of the receiving groove 53 along the second direction. The other end of the receiving groove 53 along the second direction is provided with a contoured groove for placing the cover plate h.

[0161] The pressing module 52 is mainly used to press the two core wires a and the cover plate h that pass through the lower box body c, so as to prevent the two core wires a and the cover plate h from shifting when the fixture 5 moves, which would affect the subsequent assembly process. The pressing module 52 includes two pressing blocks 521, which are located at both ends of the receiving groove 53 along the second direction. The pressing blocks 521 are divided into a pressing section and a clamping section along the first direction. The connection between the pressing section and the clamping section is hinged to the base plate 51. A compression spring is provided between the pressing section and the base plate 51. The compression spring is used to press the clamping section to press the two core wires a or the cover plate h. The two pressing sections are connected together by a connecting plate 522. Pressing the connecting plate 522 can press the two pressing blocks 521 simultaneously.

[0162] Reference Figures 24 to 26As shown, the second conveyor line 3 includes a first conveyor trough 31 extending along a first direction. Rollers are provided on both sides of the first conveyor trough 31 along the first direction. The substrate 51 is placed on the rollers, so that the fixture 5 can slide along the first conveyor trough 31. A first hook cylinder 32 is provided in the first conveyor trough 31. A hook 33 is provided at the output end of the first hook cylinder 32. The substrate 51 is hooked by the hook 33. Under the drive of the first hook cylinder 32, the substrate 51 is moved one station along the first direction. The reciprocating movement of the hook 33 pushes the fixture 5 to gradually move along the first direction.

[0163] A second conveying trough 34 is provided below the first conveying trough 31. The second conveying trough 34 has the same structure as the first conveying trough 31. The two ends of the first conveying trough 31 are the input station and the output station, respectively. A first lifting cylinder 35 is provided below the input station, and a second lifting cylinder 36 is provided below the output station.

[0164] The first lifting cylinder 35 first connects to the second conveying trough 34. The first conveying trough 31 pushes the fixture 5 onto the first lifting cylinder 35, and then lifts the fixture 5 to connect with the first conveying trough 31. The first hooking cylinder 32 drives the hook 33 to move in the opposite direction of the first direction and pass under the fixture 5. The hook 33 is connected to the output end of the first hooking cylinder 32 through an elastic element, so that the hook 33 can rotate elastically. When the hook 33 passes under the fixture 5, after the hook 33 touches the bottom of the substrate 51, it will press down elastically to ensure smooth passage. After the hook 33 passes out from under the fixture 5, it resets under the action of the elastic element, so that the hook 33 can hook the side of the substrate 51 away from the first conveying trough 31. The first hooking cylinder 32 is activated to pull the fixture 5 onto the first conveying trough 31.

[0165] The second lifting cylinder 36 first connects to the first conveying trough 31. The first conveying trough 31 pushes the fixture 5 onto the second lifting cylinder 36. The second lifting cylinder 36 descends and connects to the second conveying trough 34. The second conveying trough 34 is equipped with a second hooking cylinder 37. The output end of the second hooking cylinder 37 is also equipped with a hook 33. Similarly, the second hooking cylinder 37 drives the hook 33 to pull the fixture 5 on the second lifting cylinder 36 onto the second conveying trough 34.

[0166] This enables the cyclical use of fixture 5. During the operation of the equipment, each unit is connected to fixture 5 on the first conveying groove 31. The base plate 51 is also provided with a positioning opening 511. The first conveying groove 31 is also provided with a positioning cylinder 38 corresponding to each unit. The output end of the positioning cylinder 38 is provided with a wedge. When fixture 5 is connected to the unit, the corresponding positioning cylinder 38 is activated, and the wedge is inserted into the positioning opening 511 of the corresponding fixture 5 to position the fixture 5 and ensure accurate material feeding position.

[0167] Reference Figures 27 to 28As shown, the lower box feeding unit 12 includes a lower box discharge vibratory feeder 121 and a first feeding trough 122 that connects to the outlet of the lower box discharge vibratory feeder 121. The output end of the first feeding trough 122 is provided with a first picking station. The lower box discharge vibratory feeder 121 transports the lower box c into the first feeding trough 122. The lower box c will be arranged along the first feeding trough 122 and gradually move to the first picking station. At this time, the posture of the lower box c in the first feeding trough 122 does not correspond to the receiving groove 53 of the fixture 5.

[0168] The first material handling station is provided with a first pushing module 123 at one end along the first direction and a first reversing disk 124 at the other end along the first direction. The first pushing module 123 includes a first pushing block and a first pushing cylinder that drives the first pushing block to move. The first pushing block moves along the first direction under the drive of the first pushing cylinder to push the lower box c of the first material handling station into the first reversing disk 124. The first reversing disk 124 can rotate under the drive of the first rotary cylinder 125 to change the orientation of the lower box c in the first reversing disk 124 so that the posture of the lower box c corresponds to the receiving groove 53 of the fixture 5.

[0169] Above the first reversing plate 124, a second material transfer module 126 is provided. The second material transfer module 126 includes a second transverse cylinder 1261 and a third lifting cylinder 1262 disposed at the output end of the second transverse cylinder 1261. The output end of the third lifting cylinder 1262 is provided with a third pneumatic gripper 1263 for gripping the lower box c. The second transverse cylinder 1261 drives the third lifting cylinder 1262 to move horizontally, so that the third pneumatic gripper 1263 reaches above the first reversing plate 124. 2. Drive the third pneumatic gripper 1263 to descend, so that the third pneumatic gripper 1263 can grab the lower box c in the first reversing plate 124. Then, the third lifting cylinder 1262 resets, and the second lateral movement cylinder 1261 drives the third lifting cylinder 1262 to move, so that the third pneumatic gripper 1263 reaches above the receiving groove 53 of the corresponding fixture 5. The third lifting cylinder 1262 lowers the third pneumatic gripper 1263, and the third pneumatic gripper 1263 releases the lower box c into the receiving groove 53; thus realizing the feeding of the lower box c.

[0170] Reference Figures 29 to 30 As shown, the terminal feeding unit 13 includes a seventeenth driving device 131 and an eighteenth driving device 132 disposed at the output end of the seventeenth driving device 131. The seventeenth driving device 131 drives the eighteenth driving device 132 to move horizontally. The output end of the eighteenth driving device 132 is provided with a material picking component 133. The eighteenth driving device 132 drives the material picking component 133 to move up and down.

[0171] The material handling assembly 133 includes a first mounting plate 1331, which is connected to the output end of the eighteenth drive device 132. The first mounting plate 1331 is provided with a first top pressing column 1332, a first clamping module 1333, a second clamping module 1334, and a wire pressing module 1335. When the first mounting plate 1331 is lowered, the first top pressing column 1332 can open the pressing module 52 of the fixture 5. The first clamping module 1333 is used to clamp two core wires a, the second clamping module 1334 is used to clamp two terminals b of the two core wires a, and the wire pressing module 1335 presses the two core wires a into the wire passage f of the lower box c.

[0172] The seventeenth drive device 131 drives the eighteenth drive device 132 to move horizontally, thereby driving the first mounting plate 1331 to move horizontally. The eighteenth drive device 132 drives the material handling assembly 133 to lift up and down, thereby driving the first mounting plate 1331 to lift up and down.

[0173] In use, the first mounting plate 1331 moves down above the wire core positioning plate 1181, then the first mounting plate 1331 descends, allowing the first clamping module 1333 to clamp the two core wires a, and the second clamping module 1334 to clamp the two terminals b of the two core wires a; then the first mounting plate 1331 rises and moves above the corresponding fixture 5, and then descends again, causing the first pressing column 1332 to contact the connecting plate 522 on the fixture 5 first, opening the pressing module 5. 2. Then, the first clamping module 1333 and the second clamping module 1334 release the two core wires a and the terminal b. The terminal b is initially placed on the mounting slot e, and the two core wires a are not yet fully inserted into the wire passage f of the lower box c. Next, the wire pressing module 1335 is activated to press the two core wires a into the wire passage f of the lower box c. Finally, the first mounting plate 1331 rises, the first top pressing column 1332 leaves the connecting plate 522, and the pressing module 52 closes, allowing the pressing block to press the two core wires a.

[0174] In this embodiment, the seventeenth drive device 131 is a telescopic cylinder, and the eighteenth drive device 132 is a linear module.

[0175] In this embodiment, the first pressing column 1332 is elastically extendable and retractable, and the force of its elastic extension and retraction must be greater than the elastic force of the compression spring of the pressing module 52. Therefore, after the first pressing column 1332 is pressed down, the pressing module 52 can be opened first until the connecting plate 522 abuts against the base plate 51. At this time, the first pressing column 1332 can extend and retract, and the first mounting plate 1331 will continue to move down, allowing the first clamping module 1333 and the second clamping module 1334 to continue to move down.

[0176] In this embodiment, the first clamping module 1333 is generally a pneumatic gripper or a gripper driven by a cylinder; the second clamping module 1334 can also be a pneumatic gripper, and in order to clamp two terminals b at the same time, a fixing plate can be set between two fingers, and the two fingers press the terminal b onto the fixing plate respectively, so that the two terminals b can be clamped at the same time.

[0177] Reference Figure 31 As shown, the cover sheet feeding unit 14 includes a cover sheet discharge vibratory plate 141 and a second feeding trough 142 that connects to the outlet of the cover sheet discharge vibratory plate 141. The output end of the second feeding trough 142 is provided with a second picking station. The cover sheet discharge vibratory plate 141 gradually outputs cover sheets h, so that the cover sheets h are arranged side by side in the second feeding trough 142. The cover sheets h will move one by one to the second picking station.

[0178] It also includes a third material transfer module 143, which includes a swing arm 1431. The swing arm 1431 can be driven to rotate by a rotary cylinder or a telescopic cylinder. The swing arm 1431 is provided with a fourth lifting cylinder 1432. The output end of the fourth lifting cylinder 1432 is provided with a third mounting plate 1433. The third mounting plate 1433 is provided with a second top pressure column 1434 and a suction cup 1435. The swing arm 1431 mainly moves the position of the third mounting plate 1433 so that the third mounting plate 1433 reaches above the second material picking station or above the corresponding fixture 5. The suction cup 1435 is used to adsorb the cover plate h. When the fourth lifting cylinder 1432 drives the third mounting plate 1433 to descend, the second top pressure column 1434 first opens the pressing module 52, and then the suction cup 1435 releases the cover plate h, so that the cover plate h is placed in the contour groove of the substrate 51, and the second ring is located above the first ring.

[0179] In this embodiment, the second top pressure column 1434 has the same structure as the first top pressure column 1332.

[0180] Reference Figures 32 to 33 As shown, the terminal clamping unit 15 includes a second mounting plate 151 and a nineteenth driving device 152 for driving the second mounting plate 151 to rise and fall; the second mounting plate 151 is provided with two clamping mechanisms 153 corresponding to the terminals b in the lower box c.

[0181] The clamping mechanism 153 includes a paddle 1531 hinged to the second mounting plate 151 and a pressure plate 1532 that slides up and down on the second mounting plate 151. One end of the paddle 1531 is located above the pressure plate 1532. A spring 1533 is connected between the paddle 1531 and the second mounting plate 151. The spring 1533 is generally a tension spring.

[0182] Spring 1533 supports the lever 1531 between it and the base, keeping the lever 1531 in a preset position. One end of the lever 1531 rests on the top of the pressure plate 1532, preventing the pressure plate 1532 from rising. In use, the second mounting plate 151 descends, causing the pressure plate 1532 to descend as well. The pressure plate 1532 presses down on the terminal b. Due to the obstruction of the lever 1531, the pressure plate 1532 can press the terminal b down until it is fixed in the mounting groove e. Once in place, the terminal b cannot move down further, and the pressure plate 1532 rises under the action of the reaction force, pushing the lever 1531 to rotate, which will pull the spring 1533 away. After the second mounting plate 151 and the pressure plate 1532 no longer contact the terminal b, the spring 1533 returns to its original position.

[0183] In this embodiment, the nineteenth drive device 152 is a telescopic cylinder or a linear module.

[0184] Reference Figures 34 to 35 As shown, the upper box feeding unit 16 includes an upper box discharge vibratory feeder 161 and a third feeding trough 162 that connects to the outlet of the upper box discharge vibratory feeder 161. The output end of the third feeding trough 162 is provided with a third picking station. The upper box discharge vibratory feeder 161 gradually outputs upper boxes d, so that the upper boxes d are arranged side by side in the third feeding trough 162. The upper boxes d will move one by one to the third picking station. At this time, the posture of the upper boxes d in the third feeding trough 162 does not match the posture of the lower box c in the corresponding fixture 5.

[0185] The third material handling station is provided with a second pushing module 163 at one end along the first direction and a second reversing disk 164 at the other end along the first direction. The second pushing module 163 includes a second pushing block and a second pushing cylinder that drives the second pushing block to move. The second pushing block moves along the first direction under the drive of the second pushing cylinder, pushing the upper box d of the third material handling station into the second reversing disk 164. The second reversing disk 164 rotates under the drive of the second rotary cylinder 165 to change the orientation of the upper box d in the second reversing disk 164, so that the posture of the upper box d is adapted to the posture of the lower box c in the corresponding fixture 5.

[0186] Above the second reversing disk 164 is a fourth material transfer module 166. The fourth material transfer module 166 includes a fourth transverse cylinder 1661 and a fifth lifting cylinder 1662 located at the output end of the fourth transverse cylinder 1661. The output end of the fifth lifting cylinder 1662 is provided with an adsorption component 1663 for absorbing the upper box d. The fourth transverse cylinder 1661 drives the fifth lifting cylinder 1662 to move horizontally, thereby driving the adsorption component 1663 to move horizontally. Under the drive of the fourth transverse cylinder 1661, the adsorption component 1663 can reach above the second reversing disk 164 or above the corresponding fixture 5. Then, the fifth lifting cylinder 1662 is used to drive the adsorption component 1663 to adsorb or release the upper box d, thereby covering the upper box d with the lower box c in the corresponding fixture 5. The pin of the upper box d will pass through the second ring and the first ring in sequence.

[0187] In this embodiment, after passing through the upper box feeding unit 16, the upper box d and lower box c on the fixture 5 are initially fixed. Then, it will pass through the ultrasonic welding unit 17, which includes ultrasonic welding equipment. When the fixture 5 passes through, the ultrasonic welding equipment will weld the upper box d and lower box c on the fixture 5 together, completing the assembly of the wire box. Since the upper box d and lower box c are fixed, the second ring will also be put on the pin, so that the cover plate h will be suspended on the wire box.

[0188] Reference Figures 36 to 37 As shown, the unloading unit 18 includes a transverse linear module 181 and a sixth lifting cylinder 182 disposed at the output end of the transverse linear module 181. The output end of the sixth lifting cylinder 182 is provided with a fourth pneumatic gripper 183 for gripping the wire box.

[0189] Generally, the output end of the sixth lifting cylinder 182 is provided with a fourth mounting plate 184, and the fourth pneumatic gripper 183 is provided on the fourth mounting plate 184. The fourth mounting plate 184 is provided with a third top pressure column 185. The transverse linear module 181 drives the fourth pneumatic gripper 183 to reach above the corresponding fixture 5. The sixth lifting cylinder 182 then drives the fourth mounting plate 184 to descend, so that the third top pressure column 185 opens the pressing module 52 and uses the fourth pneumatic gripper 183 to grab the wire box. The transverse linear module 181 moves the wire box to a preset position.

[0190] In this embodiment, the fourth mounting plate 184 is provided with a flip cover module. The flip cover module includes a flip plate 186 and a gear and rack mechanism 187 that drives the flip plate 186 to rotate. When the fourth mounting plate 184 is above the corresponding fixture 5, the flip plate 186 will be above the cover plate h. Driven by the gear and rack mechanism 187, the flip plate 186 will rotate in the second direction to the lower part of the fourth pneumatic gripper 183. Therefore, when the fourth pneumatic gripper 183 picks up the wire box, the flip plate 186 will rotate, causing the cover plate h to bend and the plug i on the cover plate h to be inserted into the insertion hole g of the lower box body c.
