Description

Technical Field

[0001] This invention relates to the field of assembly equipment technology, and in particular to a cable connector assembly machine. Background Technology

[0002] With the rapid development of medical technology, medical devices have placed extremely stringent requirements on the performance, safety, reliability, and compliance of electrical interconnection systems, far exceeding those in the industrial and consumer electronics fields. As the core hub for signal and power transmission in medical devices, medical interconnection systems are crucial components for ensuring diagnostic accuracy, patient electrical safety, and equipment operational stability. Consequently, new medical connection elements have emerged. These new connection elements have evolved from traditional "mechanical conductive structures" into modular electronic circuit units that integrate electrical interconnection, impedance matching, signal conditioning, EMC protection, sensing and detection, and even edge control functions. Their manufacturing process now fully covers the entire process of precision electronic circuit manufacturing. The core technological goal is to achieve precise controllability of the electrical performance of the interconnection system, high integration of functions, and miniaturization of the physical structure. This is the core link that determines the upper limit performance of the interconnection system. Connector and cable assembly is an essential step in achieving signal and power transmission in the interconnection system. It involves terminating prefabricated connectors and corresponding cables to achieve electrical and mechanical connections.

[0003] Existing equipment with a split layout has separate equipment for stripping, pipe installation, and terminal connection processes. The transfer and secondary loading and positioning of cables need to be completed manually, which not only increases labor costs but also lengthens the production cycle and significantly reduces assembly efficiency. At the same time, it increases the probability that the metal segments of the cables will be deformed due to factors such as touching, making it impossible to proceed to the next step. Summary of the Invention

[0004] To address the above problems, the present invention provides a cable connector assembly machine.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a cable connector assembly machine, comprising a chain plate type conveyor, wherein the conveyor frame is provided with a stripping mechanism for stripping the cable to be assembled, an installation mechanism for installing a connector tube on the insulation sidewall of the stripped cable, and a mating mechanism for connecting the conductive terminals of the connector to the connector tube. The connector tube is made of zinc alloy material to improve the corrosion resistance of the cable connector and protect the internal conductive components from corrosion. The chain plate of the conveyor is provided with a positioning mechanism, which is used to automatically clamp or release the cable when the positioning mechanism moves with the chain plate.

[0006] By adopting the above technical solution, during operation, the cable to be assembled is clamped and fixed at the loading station by the positioning mechanism in one go, and is synchronously conveyed with the chain plate, maintaining a stable positioning state throughout the process, and completing the entire process in sequence: first, the stripping mechanism strips the cable ends, then the installation mechanism assembles the connector to the cable insulation sidewall, and finally the docking mechanism completes the connection between the connector conductive terminals and the connector; when the finished cable runs to the unloading station, the positioning mechanism automatically releases to complete the unloading, eliminating the cumbersome operation of the existing technology that requires workers to carry the stripped cable to the docking and installation station for reloading, simplifying the steps of the existing technology and improving work efficiency.

[0007] Furthermore, the positioning mechanism includes a positioning component, which includes a positioning shell fixed to the conveyor chain plate and having an internal hollow structure. The top of the positioning shell is provided with two sliding through holes communicating with the inside of the positioning shell. The positioning component also includes clamping blocks slidably disposed in the sliding through holes and crossbars fixed in the sliding through holes and slidingly engaged with the clamping blocks. The number of clamping blocks, the number of crossbars, and the number of sliding through holes are all equal and their positions correspond one-to-one. The side walls of the two clamping blocks that are close to each other are provided with arc surfaces adapted to the cable insulation surface. One end of the positioning shell is provided with a placement groove with an arc structure for placing the cable. The positioning mechanism also includes a distance adjustment component for adjusting the distance between the two clamping blocks.

[0008] By adopting the above technical solution, during operation, the pitch adjustment component first drives the two clamping blocks to slide in the opposite direction along the crossbar in the corresponding sliding through hole, opening the clamping space. The mechanism then moves to the loading station with the chain plate. After the cable to be assembled is inserted into the arc-shaped placement groove at the end of the positioning shell to complete the radial pre-positioning, the pitch adjustment component drives the two clamping blocks to slide towards each other along the crossbar. The arc-shaped surfaces on the clamping blocks that are adapted to the cable insulation surface fit and clamp the outer wall of the cable, completing the locking and positioning. The clamping state is maintained throughout the conveying process with the chain plate. When the finished cable moves to the unloading station, the pitch adjustment component drives the two clamping blocks to slide in the opposite direction to release the clamping, completing the unloading. The unloaded mechanism then enters the next round of operation cycle with the chain plate.

[0009] Furthermore, the adjusting assembly includes an adjusting plate slidably disposed within the positioning housing, an adjusting column rotatably mounted on the bottom of the clamping block, a vertical block fixed to the bottom of the adjusting plate, and a limiting rod fixed within the positioning housing and slidably engaged with the vertical block. Each clamping block is provided with two adjusting columns. The top of the adjusting plate is provided with an adjusting through hole that slidably engages with the adjusting column. Two adjacent adjusting through holes form an "eight" shape. The positioning mechanism also includes a displacement assembly for driving the adjusting plate to move.

[0010] By adopting the above technical solution, during operation, the adjusting plate is slidably assembled in the inner cavity of the positioning shell, and the vertical block at its bottom slides in cooperation with the limiting rod fixed in the positioning shell, constraining the adjusting plate to only make linear reciprocating movements along the axis of the limiting rod, thus preventing movement sway. The two adjusting columns at the bottom of each clamping block are inserted into the adjusting through holes arranged in a figure-eight pattern on the adjusting plate, forming a sliding transmission cooperation. When the displacement component drives the adjusting plate to move forward, the hole wall of the adjusting through hole synchronously pushes the two sets of adjusting columns, causing the two clamping blocks to slide synchronously in the opposite direction along the crossbar, expanding the clamping distance and completing the release action, which is suitable for cable loading and finished product unloading. When the displacement component drives the adjusting plate to move in the reverse reset direction, the adjusting through hole drives the two clamping blocks to slide synchronously towards each other along the crossbar in the opposite direction, reducing the distance. The cable is clamped by the arc surface on the clamping block that is compatible with the cable, completing the centering and locking, and maintaining stable clamping throughout the entire conveying process with the chain plate.

[0011] Furthermore, the displacement assembly includes a spring fixed between the vertical block and the inner wall of the positioning shell, a slide rod that passes through the side wall of the positioning shell and slides in cooperation with the positioning shell, a ball bearing movably mounted on the end of the slide rod away from the positioning shell, and an adjusting block fixed to the conveyor frame. The end of the slide rod near the inside of the positioning shell is fixedly connected to the vertical block. The adjusting block is an isosceles trapezoid, and the distance between the two inclined sides of the adjusting block gradually increases from the slide rod to the ball bearing.

[0012] By adopting the above technical solution, this component uses an isosceles trapezoidal adjusting block fixed on the conveyor frame as the fixed trigger end, and a slide rod and spring that move synchronously with the chain plate as the moving end. When the positioning mechanism runs with the chain plate in the processing area, the ball first moves from one inclined side of the adjusting block to the plane of the adjusting block. During this process, the inclined side squeezes the ball, causing the slide rod to slide into the inner cavity of the positioning shell, and simultaneously compresses the spring. The spring causes the vertical block and the adjusting plate fixed to the vertical block to move, thereby automatically completing the clamping action. Then the ball moves from the plane of the adjusting block to the other inclined side of the adjusting block and disengages from the other inclined side of the adjusting block. During this process, the spring gradually returns to its original position and causes the vertical block and the adjusting plate fixed to the vertical block to move in the opposite direction, thereby automatically completing the releasing action.

[0013] Furthermore, the stripping mechanism includes a stripping assembly, which includes a first frame fixed to the conveyor frame, a first gripper slidably disposed on the first frame, and two mounting shells respectively fixed to the two grippers of the first gripper and having an internal hollow structure. The first gripper can automatically slide along the length of the cable. The mounting shell has an arc-shaped through hole coaxially disposed with the cable in the clamped state on the side wall away from the first gripper. Both ends of the arc-shaped through hole extend to the side wall of the mounting shell near the middle of the first gripper. The stripping assembly also includes a stripping knife slidably disposed in the arc-shaped through hole. The number of mounting shells, the number of stripping knives, and the number of arc-shaped through holes are all equal and their positions correspond one-to-one. The stripping mechanism also includes a rotating component for driving the stripping knife to rotate along the axis of the arc-shaped through hole.

[0014] By adopting the above technical solution, when the positioning mechanism holding the cable to be processed moves to the stripping station and locks with the chain plate, the first gripper feeds to the cable end station and performs clamping. The two mounting shells close towards each other, and the semi-circular arc through holes on them form a complete circumferential guide channel coaxial with the cable, surrounding the area of ​​the cable to be stripped. At the same time, the blade of the stripping knife accurately penetrates into the cable insulation layer and adheres to the surface of the metal layer. Then the rotating component starts, driving the stripping knife to slide circumferentially along the axis of the arc through hole (i.e., the central axis of the cable), completely circumferentially cutting the insulation layer along the circumference of the cable, accurately cutting through the insulation layer without damaging the internal wire core. After the circumferential cutting is completed, the first gripper drives the closed mounting shell and the stripping knife to move axially backward, completely peeling the circumferentially cut insulation layer from the cable end. After the peeling is completed, the first gripper opens and resets, and the stripped cable is still held by the positioning mechanism throughout the process and is directly transported to the next process with the chain plate.

[0015] Furthermore, the number of rotating components is equal to the number of mounting shells, and their positions correspond one-to-one. Each rotating component includes an arc rack slidably disposed within the mounting shell, a drive rod that passes through the side wall of the mounting shell and is rotatably connected to the mounting shell, a rotating gear fixedly sleeved on the drive rod and located within the mounting shell, a rotary motor fixed to the first gripper and driving the drive rod to rotate, and a first cylinder fixed to the first frame and driving the first gripper to move. The peeling knife is fixed to the arc rack, and both ends of the arc rack pass through the side wall of the first gripper near the middle of the mounting shell and slide in cooperation with the mounting shell. The rotating gear meshes with the arc rack.

[0016] By adopting the above technical solution, the rotary motor starts, and drives the rotary gear to rotate through the drive rod. Through the meshing transmission between the rotary gear and the arc rack, the arc rack is driven to slide along the arc guide path inside the mounting housing, simultaneously driving the stripping blade fixed on the arc rack to smoothly feed along the circumferential path coaxial with the cable, completing the precise circumferential cutting of the cable insulation layer. After the circumferential cutting is completed, the first cylinder drives the first gripper to move axially backward, driving the stripping blade to completely peel off the cut insulation layer from the end of the cable. After the operation is completed, the rotary motor reverses to reset the arc rack and stripping blade, and the first cylinder drives the first gripper to return to its position, waiting for the next round of operation. The rotational power is converted into the coaxial circumferential feeding motion of the stripping blade, and the drive of the first gripper feeding and stripping action is integrated to realize the precise circumferential cutting and automatic stripping of the cable insulation layer.

[0017] Furthermore, the installation mechanism includes an installation assembly, which includes a second frame fixed to the conveyor frame and having an L-shaped structure, and a second cylinder fixed to the second frame. The piston rod of the second cylinder passes through the vertical section of the second frame and slides in cooperation with the second frame. The installation assembly also includes an installation sleeve fixed to the end of the piston rod of the second cylinder. The inner wall of the installation sleeve is inserted into the connecting pipe. The inner wall of the connecting pipe is provided with a fusion layer. The installation mechanism also includes a thermoforming assembly for melting and fixing the connecting pipe to the cable surface.

[0018] By adopting the above technical solution, before operation, the connector with a molten layer on its inner wall is pre-inserted and positioned on the inner wall of the installation sleeve. When the stripped cable moves to this station with the chain plate, the positioning mechanism still maintains a stable clamping of the cable, ensuring that the cable and the installation sleeve are coaxially and precisely aligned. Then, the second cylinder is activated, and the piston rod extends to drive the installation sleeve to feed precisely along the cable axis, smoothly fitting the connector into the preset position on the insulation side wall of the stripped cable. After it is in place, the hot melt assembly is activated to heat the molten layer on the inner wall of the connector. After the molten layer melts, it fully wets the surface of the cable insulation. After cooling and solidification, a firm bond is achieved between the connector and the cable. After fixing, the piston rod of the second cylinder retracts, causing the installation sleeve to detach from the connector and reset, waiting for the next round of operation, thus realizing the automated assembly and firm fixing of the connector.

[0019] Furthermore, the hot-melt assembly includes a limiting plate fixed to the vertical section of the second frame, an annular block fixed inside the mounting sleeve and coaxially arranged with the mounting sleeve, and a hot-melt plate fixed to the inner wall of the mounting sleeve and coaxially arranged with the mounting sleeve. The hot-melt plate is connected to a power source. The connecting pipe passes through the hot-melt plate and is inserted into it. The top of the limiting plate is provided with an arc groove. The outer wall of the mounting sleeve and the outer wall of the large end of the connecting pipe are in contact with the surface of the arc groove.

[0020] By adopting the above technical solution, the connecting pipe is pre-inserted into the installation sleeve, and the front end is abutted against the coaxial annular block to complete the axial pre-installation positioning. The pipe body is coaxially embedded in the hot melt plate that is ready to be triggered by power. When the second cylinder drives the installation sleeve to feed, and precisely installs the connecting pipe into the preset position on the side wall of the cable insulation, the outer wall of the installation sleeve and the outer wall of the large end of the connecting pipe are simultaneously attached to the arc groove of the limiting plate, completing the radial support and axial limit of the feed to the position, and eliminating overtravel and coaxiality deviation. Then, the hot melt plate is powered on and starts to heat the connecting pipe evenly in 360°. The heat is quickly transferred to the molten layer on the inner wall of the connecting pipe to melt it evenly and fully wet the outer wall of the cable insulation. After heating is completed, the hot melt plate is powered off, and the molten layer cools and solidifies naturally, realizing a firm coaxial bond between the connecting pipe and the cable. Finally, the second cylinder drives the installation sleeve to retract and reset, and smoothly detaches from the fixed connecting pipe, completing the whole process and waiting for the next cycle. The double limiting structure ensures the coaxial accuracy and positional accuracy of the assembly and hot melt.

[0021] Furthermore, the docking mechanism includes a docking assembly, which includes a third frame fixed to the conveyor frame and having an L-shaped structure, and a third cylinder fixed to the third frame. The piston rod of the third cylinder passes through the vertical section of the third frame and slides in cooperation with the third frame. The docking assembly also includes a circular plate fixed to the end of the piston rod of the third cylinder and a docking block rotatably mounted on the end of the circular plate away from the third cylinder. The end of the docking block away from the circular plate has a driving groove with a regular hexagonal structure. The driving groove is inserted into the hexagonal segment of the connector's conductive terminal. The docking mechanism also includes a rotating assembly for driving the docking block to rotate and keeping the docking tube in a stationary state.

[0022] By adopting the above technical solution, during operation, the cable with pre-installed connector is moved to the workstation along the chain plate and clamped and fixed by the positioning mechanism throughout the process, keeping the connector stationary. The hexagonal segment of the connector's conductive terminal is pre-inserted into the regular hexagonal drive groove at the end of the mating block to achieve circumferential limiting and synchronous torque transmission. Then, the third cylinder is activated, and the piston rod extends to drive the circular plate and the mating block to be precisely fed along the cable axis, so that the conductive terminal and the mating end of the connector are precisely fitted. Then, the rotating component is activated, driving the mating block to rotate around the axis, and driving the conductive terminal to rotate synchronously through the drive groove, forming a relative rotation with the stationary connector, completing the threaded fastening connection between the two. After the docking is completed, the rotating component stops rotating, and the third cylinder drives the mating block to retract and reset, disengaging from the conductive terminal, completing the entire docking operation. The cable enters the unloading stage along the chain plate, realizing the automated and precise fastening connection between the connector's conductive terminal and the cable pre-installed connector.

[0023] Furthermore, the rotating assembly includes a mounting bracket fixed to the circular plate, a gear ring fixedly sleeved on the docking block, a rotating motor fixed to the mounting bracket, a rotating gear fixedly sleeved on the output end of the rotating motor, and a second gripper fixed to the mounting bracket. The two grippers of the second gripper are used to clamp the large end of the docking tube to be docked.

[0024] By adopting the above technical solution, the third cylinder drives the circular plate to feed into position, so that the conductive terminal and the connector are precisely fitted together. At the same time, the second gripper starts synchronously, clamping the large end of the connector to form a double lock, completely restricting the circumferential rotation of the connector and ensuring that it remains stationary throughout the process. Then, the rotating motor starts, driving the rotating gear at the output end to rotate. Through the meshing transmission between the rotating gear and the fixed gear ring on the mating block, the mating block is driven to rotate smoothly. The hexagonal drive groove at the end of the mating block drives the conductive terminal of the connector to rotate synchronously, forming a stable relative rotation with the stationary connector, completing the precise fastening and docking of the two. After tightening, the rotating motor stops, the second gripper releases its lock, and the third cylinder drives the overall structure to retract and reset, waiting for the next round of operation. With the gripper locking to ensure that the connector remains stationary, the automated tightening and docking of the terminal and the connector is precisely completed.

[0025] In summary, the present invention has the following beneficial effects: By improving the existing structure, this application eliminates the cumbersome operation of having workers transport the stripped cable to the docking and installation station for reloading, simplifying the steps and improving work efficiency. Simultaneously, it avoids situations where the cable's metal segments deform due to contact or other factors during operation, preventing further processing. Attached Figure Description

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-13As shown in the illustration, this application discloses a cable connector assembly machine, including a conveyor 1, a stripping mechanism 2, an installation mechanism 3, a docking mechanism 4, and a positioning mechanism 5. The stripping mechanism 2 is used to strip the insulation of the cable to be assembled. The installation mechanism 3 is used to install the connector onto the insulation sidewall of the stripped cable. The docking mechanism 4 is used to connect the conductive terminals of the connector to the connector. The positioning mechanism 5 automatically clamps or releases the cable as it moves with the chain plate. During operation, the cable to be assembled is clamped and fixed at the loading station by the positioning mechanism 5 in one go, and is synchronously conveyed with the chain plate, maintaining a stable positioning state throughout the process, completing the entire process sequentially: first, the stripping mechanism 2 strips the cable ends, then the installation mechanism 3 assembles the connector onto the insulation sidewall of the cable, and finally the docking mechanism 4 connects the conductive terminals of the connector to the connector. When the finished cable reaches the unloading station, the positioning mechanism 5 automatically releases to complete the unloading, eliminating the cumbersome operation of having workers carry the stripped cable to the docking and installation station for reloading, simplifying the steps of the prior art, and improving work efficiency.

[0030] The positioning mechanism 5 is mounted on the chain plate of conveyor 1. The positioning mechanism 5 includes a positioning component 51, a pitch adjustment component 52, and a displacement component 53. The positioning shell 511 is fixed to the chain plate of conveyor 1 and has an internal hollow structure. The top of the positioning shell 511 has two sliding through holes 6 that communicate with the inside of the positioning shell 511. One end of the positioning shell 511 has a placement groove 7 with an arc-shaped structure for placing cables. The clamping block 512 is slidably disposed in the sliding through hole 6. The crossbar 513 is fixed in the sliding through hole 6 and slides in cooperation with the clamping block 512. The number of clamping blocks 512, the number of crossbars 513, and the number of sliding through holes 6 are all equal and their positions correspond one-to-one. The side walls of the two clamping blocks 512 that are close to each other are provided with arc-shaped surfaces that are adapted to the surface of the cable insulation. During operation, the pitch adjustment component 52 first drives the two clamping blocks 512 to slide in the opposite direction along the crossbar 513 in the corresponding sliding through hole 6, opening the clamping space. The mechanism then moves to the loading station with the chain plate. After the assembled cable is inserted into the arc-shaped placement groove 7 at the end of the positioning shell 511 to complete the radial pre-positioning, the pitch adjustment component 52 drives the two clamping blocks 512 to slide towards each other along the crossbar 513. The arc-shaped surfaces on the clamping blocks 512 that are adapted to the cable insulation surface fit together and clamp the outer wall of the cable, completing the locking and positioning. The clamping state is maintained throughout the conveying process with the chain plate. When the finished cable moves to the unloading station, the pitch adjustment component 52 drives the two clamping blocks 512 to slide in the opposite direction to release the clamping, completing the unloading. The unloaded mechanism then enters the next round of operation with the chain plate.

[0031] The distance adjustment assembly 52 is used to adjust the distance between the two clamping blocks 512. The distance adjustment assembly 52 includes an adjustment plate 521, an adjustment column 522, a vertical block 523, and a limiting rod 524. The adjustment plate 521 is slidably disposed within the positioning shell 511. The top of the adjustment plate 521 has an adjustment through hole 8 that slides with the adjustment column 522. Two adjacent adjustment through holes 8 form an "eight" shape. The adjustment column 522 is rotatably mounted on the bottom of the clamping block 512. Each clamping block 512 has two adjustment columns 522. The vertical block 523 is fixed to the bottom of the adjustment plate 521. The limiting rod 524 is fixed within the positioning shell 511 and slides with the vertical block 523. During operation, the adjusting plate 521 is slidably assembled in the inner cavity of the positioning shell 511. The vertical block 523 at its bottom slides in cooperation with the limiting rod 524 fixed in the positioning shell 511, which restricts the adjusting plate 521 to only make linear reciprocating motion along the axis of the limiting rod 524, thus preventing the movement from deflecting. The two adjusting columns 522 at the bottom of each clamping block 512 are inserted into the adjusting through holes 8 arranged in a figure-eight pattern on the adjusting plate 521, forming a sliding transmission cooperation. When the displacement component 53 drives the adjustment plate 521 to move forward, the wall of the adjustment through hole 8 synchronously pushes the two sets of adjustment columns 522, causing the two clamping blocks 512 to slide synchronously in the opposite direction along the crossbar 513, expanding the clamping distance and completing the release action, which is suitable for cable loading and finished product unloading; when the displacement component 53 drives the adjustment plate 521 to move in the reverse reset direction, the adjustment through hole 8 drives the two clamping blocks 512 to slide synchronously towards each other along the crossbar 513 in the opposite direction, reducing the distance, and clamping the cable by fitting the arc surface on the clamping block 512 that is compatible with the cable, completing the centering and locking, and maintaining stable clamping throughout the entire conveying process with the chain plate.

[0032] The displacement assembly 53 is used to drive the adjusting plate 521 to move. The displacement assembly 53 includes a spring 531, a slide rod 532, a ball bearing 533, and an adjusting block 534. The spring 531 is fixed between the vertical block 523 and the inner wall of the positioning shell 511. The end of the slide rod 532 near the inside of the positioning shell 511 is fixedly connected to the vertical block 523, and the slide rod 532 passes through the side wall of the positioning shell 511 and slides in cooperation with the positioning shell 511. The ball bearing 533 is movably installed at the end of the slide rod 532 away from the positioning shell 511. The adjusting block 534 is fixed to the frame of the conveyor 1. The adjusting block 534 is an isosceles trapezoid, and the distance between the two inclined sides of the adjusting block 534 gradually increases from the slide rod 532 to the ball bearing 533. This component uses an isosceles trapezoidal adjusting block 534 fixed on the conveyor frame 1 as the fixed trigger end, and a slide rod 532 and a spring 531 that move synchronously with the chain plate as the moving ends. When the positioning mechanism 5 runs with the chain plate in the processing area, the ball 533 first moves from one inclined side of the adjusting block 534 to the plane of the adjusting block 534. During this process, the inclined side squeezes the ball 533, causing the slide rod 532 to slide into the inner cavity of the positioning shell 511, and simultaneously compresses the spring 531. The spring 531 drives the vertical block 523 and the adjusting plate 521 fixed to the vertical block 523 to move, thereby automatically completing the clamping action. Then, the ball 533 moves from the plane of the adjusting block 534 to the other inclined side of the adjusting block 534 and disengages from the other inclined side of the adjusting block 534. During this process, the spring 531 gradually returns to its original position and drives the vertical block 523 and the adjusting plate 521 fixed to the vertical block 523 to move in the opposite direction, thereby automatically completing the releasing action.

[0033] The stripping mechanism 2 is mounted on the frame of conveyor 1. The stripping mechanism 2 includes a stripping component 21 and a rotating component 22. The stripping component 21 includes a first frame 211, a first gripper 212, a mounting shell 213, and a stripping blade 214. The first frame 211 is fixed to the frame of conveyor 1, and the first gripper 212 is slidably mounted on the first frame 211. The first gripper 212 is an electric gripper. There are two mounting shells 213, which are respectively fixed to the two grippers of the first gripper 212 and have a hollow internal structure. An arc-shaped through hole 9 is provided through the side wall of the mounting shell 213 away from the first gripper 212, which is coaxial with the cable when it is clamped. Both ends of the arc-shaped through hole 9 extend to the side wall of the mounting shell 213 near the middle of the first gripper 212. The peeling knife 214 is slidably disposed in the arc-shaped through hole 9. The number of mounting shells 213, the number of peeling knives 214, and the number of arc-shaped through holes 9 are all equal and their positions correspond one-to-one. When the positioning mechanism 5 holding the cable to be processed moves to the stripping station and locks with the chain plate, the first gripper 212 feeds to the cable end station and performs clamping. The two mounting shells 213 close towards each other, and the semi-circular through holes 9 on them form a complete circumferential guide channel coaxial with the cable, surrounding the area of ​​the cable to be stripped. At the same time, the blade of the stripping knife 214 accurately penetrates into the cable insulation layer and adheres to the surface of the metal layer. Then the rotating component 22 starts, driving the stripping knife 214 to slide circumferentially along the axis of the arc through hole 9 (i.e., the central axis of the cable), completely circumferentially cutting the insulation layer along the circumference of the cable, accurately cutting through the insulation layer without damaging the internal wire core. After the circumferential cutting is completed, the first gripper 212 drives the closed mounting shell 213 and the stripping knife 214 to move axially backward, completely peeling the circumferentially cut insulation layer from the cable end. After the peeling is completed, the first gripper 212 opens and resets. The stripped cable is still held by the positioning mechanism 5 throughout the process and is directly transported to the next process with the chain plate.

[0034] The rotating assembly 22 drives the peeling knife 214 to rotate along the axis of the arc-shaped through hole 9. The number of rotating assemblies 22 is equal to the number of mounting shells 213, and their positions correspond one-to-one. The rotating assembly 22 includes an arc-shaped rack 221, a drive rod 222, a rotating gear 223, a rotary motor 224, and a first cylinder 225. The peeling knife 214 is fixed on the arc-shaped rack 221. Both ends of the arc-shaped rack 221 pass through the side wall of the first gripper 212 near the middle of the mounting shell 213 and slide in engagement with the mounting shell 213. The arc-shaped rack 221 is slidably disposed within the mounting shell 213. The drive rod 222 passes through the side wall of the mounting shell 213 and is rotatably connected to the mounting shell 213. The rotating gear 223 is fixedly sleeved on the drive rod 222 and located within the mounting shell 213. Rotary gear 223 meshes with arc rack 221. Rotary motor 224 is fixed to the first gripper 212 and drives drive rod 222 to rotate. First cylinder 225 is fixed to the first frame 211 and drives the first gripper 212 to move. The piston rod of the first cylinder 225 passes through the side wall of the first frame 211 and slides in cooperation with the first frame 211. The end of the piston rod of the first cylinder 225 is fixedly connected to the first gripper 212. The rotary motor 224 starts, driving the rotary gear 223 to rotate via the drive rod 222. Through the meshing transmission between the rotary gear 223 and the arc rack 221, the arc rack 221 is driven to slide along the arc guide path inside the mounting housing 213, simultaneously driving the stripping blade 214 fixed on the arc rack 221 to smoothly feed along a circumferential path coaxial with the cable, completing a precise circumferential cut of the cable insulation layer. After the circumferential cut is completed, the first cylinder 225 drives the first gripper 212 to move axially backward, driving the stripping blade 214 to completely peel off the cut insulation layer from the cable end. After the operation is completed, the rotary motor 224 reverses to reset the arc rack 221 and the stripping blade 214, and the first cylinder 225 drives the first gripper 212 to return to its original position, waiting for the next round of operation. The rotational power is converted into the coaxial circumferential feed motion of the stripping blade 214, and the drive of the feed and stripping action of the first gripper 212 is integrated to realize the precise circumferential cut and automatic stripping of the cable insulation layer.

[0035] The mounting mechanism 3 is mounted on the frame of conveyor 1. The mounting mechanism 3 includes a mounting component 31 and a hot-melt component 32. The mounting component 31 includes a second frame 311, a second cylinder 312, and a mounting sleeve 313. The second frame 311 is fixed to the frame of conveyor 1 and has an L-shaped structure. The second cylinder 312 is fixed to the second frame 311. The piston rod of the second cylinder 312 passes through the vertical section of the second frame 311 and slides within it. The mounting sleeve 313 is fixed to the end of the piston rod of the second cylinder 312. The inner wall of the mounting sleeve 313 is inserted into a connecting pipe, the inner wall of which has a molten layer. Before operation, the connector with a molten layer on its inner wall is pre-inserted and positioned on the inner wall of the mounting sleeve 313. When the stripped cable moves to this station with the chain plate, the positioning mechanism 5 maintains a stable clamp on the cable, ensuring that the cable and the mounting sleeve 313 are coaxially and precisely aligned. Then, the second cylinder 312 is activated, and the piston rod extends to drive the mounting sleeve 313 to feed precisely along the cable axis, smoothly fitting the connector into the preset position on the insulation side wall of the stripped cable. After it is in place, the hot melt assembly 32 is activated to heat the molten layer on the inner wall of the connector. After the molten layer melts, it fully wets the surface of the cable insulation. After cooling and solidification, a firm bond is achieved between the connector and the cable. After the fixing is completed, the piston rod of the second cylinder 312 retracts, causing the mounting sleeve 313 to disengage from the connector and reset, waiting for the next round of operation, thus realizing the automated assembly and firm fixing of the connector.

[0036] The hot-melt assembly 32 is used to fuse and fix the connector to the cable surface. The hot-melt assembly 32 includes a limiting plate 321, an annular block 322, and a hot-melt plate 323. The limiting plate 321 is fixed to the vertical section of the second frame 311. The top of the limiting plate 321 has an arc groove 10. The outer wall of the mounting sleeve 313 and the outer wall of the large end of the connector are in contact with the surface of the arc groove 10. The annular block 322 is fixed inside the mounting sleeve 313 and is coaxially arranged with the mounting sleeve 313. The hot-melt plate 323 is fixed to the inner wall of the mounting sleeve 313 and is coaxially arranged with the mounting sleeve 313. The hot-melt plate 323 is connected to a power source. The connector passes through the hot-melt plate 323 and is inserted into it. The connecting pipe is pre-inserted into the installation sleeve 313, with its front end abutting against the coaxial annular block 322 for axial pre-positioning. The pipe body is coaxially embedded into the heat-fusion plate 323, ready for power-on triggering. When the second cylinder 312 drives the installation sleeve 313 to feed, precisely fitting the connecting pipe to the preset position on the cable insulation sidewall, the outer wall of the installation sleeve 313 and the outer wall of the large end of the connecting pipe simultaneously fit into the arc groove 10 of the limiting plate 321, completing the radial support and axial limit of the feed, preventing overtravel and coaxiality deviation. Then, the heat-fusion plate 323... Upon power-on, the connector is heated evenly in a 360° surround motion. The heat is rapidly transferred to the molten layer on the inner wall of the connector, causing it to melt evenly and fully saturate the outer wall of the cable insulation. After heating is complete, the hot melt plate 323 is de-energized, and the molten layer cools and solidifies naturally, achieving a firm coaxial bond between the connector and the cable. Finally, the second cylinder 312 drives the installation sleeve 313 to retract and reset, smoothly disengaging from the fixed connector, completing the entire process and awaiting the next cycle. The double-limiting structure ensures the coaxial precision and positional accuracy of the assembly and hot melt.

The docking component 41 includes a third frame 411, a third cylinder 412, a circular plate 413, and a docking block 414. The third frame 411 is fixed to the frame of conveyor 1 and has an L-shaped structure. The third cylinder 412 is fixed to the third frame 411. The piston rod of the third cylinder 412 passes through the vertical section of the third frame 411 and slides in cooperation with the third frame 411. The circular plate 413 is fixed to the end of the piston rod of the third cylinder 412. The docking block 414 is rotatably mounted on the end of the circular plate 413 away from the third cylinder 412. The end of the docking block 414 away from the circular plate 413 has a hexagonal drive groove 11, which is inserted into the hexagonal segment of the connector's conductive terminal. During operation, the cable with pre-installed connector is moved to the workstation by the chain plate and clamped and fixed by the positioning mechanism 5 throughout the process, keeping the connector stationary. The hexagonal segment of the connector's conductive terminal is pre-inserted into the regular hexagonal drive groove 11 at the end of the mating block 414 to achieve circumferential limiting and synchronous torque transmission. Then, the third cylinder 412 is activated, and the piston rod extends to drive the circular plate 413 and the mating block 414 to be precisely fed along the cable axis, so that the conductive terminal and the mating end of the connector are precisely fitted. Then, the rotating component 42 is activated, driving the mating block 414 to rotate around the axis, and driving the conductive terminal to rotate synchronously through the drive groove 11, forming a relative rotation with the stationary connector, completing the threaded fastening connection between the two. After the docking is completed, the rotating component 42 stops rotating, and the third cylinder 412 drives the mating block 414 to retract and reset, disengaging from the conductive terminal, completing the entire docking operation. The cable enters the unloading stage with the chain plate, realizing the automated and precise fastening docking of the connector's conductive terminal and the cable pre-installed connector.

[0038] The rotating assembly 42 drives the docking block 414 to rotate and keeps the docking tube stationary. The rotating assembly 42 includes a mounting bracket 421, a gear ring 422, a rotating motor 423, a rotating gear 424, and a second gripper 425.

The rotating motor 423 is fixed to the mounting bracket 421, and the rotating gear 424 is fixedly sleeved on the output end of the rotating motor 423. The second gripper 425 is fixed to the mounting bracket 421, and its two grippers are used to clamp the large end of the docking tube to be docked. The second gripper 425 is an electric gripper. The third cylinder 412 drives the circular plate 413 to feed into position, ensuring precise contact between the conductive terminal and the connector. Simultaneously, the second gripper 425 starts, clamping the large end of the connector to form a double lock, completely restricting the circumferential rotation of the connector and ensuring it remains stationary throughout the process. Subsequently, the rotating motor 423 starts, driving the rotating gear 424 at the output end to rotate. Through the meshing transmission between the rotating gear 424 and the fixed gear ring 422 on the docking block 414, the docking block 414 is driven to rotate smoothly. The hexagonal drive groove 11 at the end of the docking block 414 drives the connector's conductive terminal to rotate synchronously, forming a stable relative rotation with the stationary connector, completing the precise fastening connection between the two. After tightening, the rotating motor 423 stops, the second gripper 425 releases its lock, and the third cylinder 412 drives the entire structure to retract and reset, awaiting the next round of operation. The gripper lock ensures the connector remains stationary, precisely completing the automated tightening connection between the terminal and the connector.
