Description

Technical Field

[0001] The invention relates to the technical field of cable terminal connection, in particular to an automatic cable assembly insertion device. Background Art

[0002] Cable terminals are a common component used to connect cables to electrical equipment or systems. They are usually made of metal materials with good electrical conductivity. Cable terminals can ensure the reliability and safety of electrical connections. The quality of the connection between the cable and the terminal is crucial and directly related to the normal use of the electrical system. The common method of connecting cables and terminals is to insert the connection. This method is simple and convenient. In the process of connecting the terminal and the cable, it is necessary to cut the cable to a suitable length and strip the insulation layer at the end of the cable to expose the wire harness conductor inside it. Then, insert the exposed wire harness conductor into the terminal slot to complete the stable connection between the cable terminal and the cable.

[0003] However, the following problems still exist in the process of inserting the wire harness conductor into the cable terminal: (1) The stripping length and cutting depth of the cable sheath are difficult to control. If the stripping length is too long, the wire harness conductor will remain outside the terminal, affecting normal use and safety. If the stripping length is insufficient, the connectivity and stability between the cable and the terminal will be poor. If the cutting depth is too deep, the wire harness conductor may be damaged, thereby affecting the quality of the wire harness conductor. If the cutting depth is insufficient, the cable sheath will be adhered to each other, making it more difficult to strip the cable sheath.

[0004] (2) After stripping, the conductor part of the wire harness is prone to change from a tight state before stripping to a slightly scattered state. The slightly scattered state is not conducive to the neat and quick insertion of the wire harness conductor into the terminal slot, which increases the difficulty of installation and is also prone to bending and deformation of the wire harness conductor.

[0005] (3) The wiring harness conductor is not inserted into the terminal to a sufficient degree, and the connection between the two needs to be improved in terms of adequacy and tightness, which in turn reduces the reliability of the overall connection quality. Summary of the invention

[0035] During operation: first, the terminal required for connection can be placed horizontally on the upper end of the fixed plate 212 with the opening facing right, and the connecting hole on the left end of the terminal can be passed through the positioning column.

After the pushing column 316 slides through the annular sleeve 311, a baffle 317 is installed. The outer side of the pushing column 316 is provided with a connecting spring located between the corresponding baffle 317 and the outer ring surface of the annular sleeve 311. The front and rear ends of the connecting plate are hinged with connecting rods 319 that are hinged with the corresponding baffles 317 located on the front and rear sides of the annular sleeve 311. The sides of the front and rear arc-shaped push plates 314 that are close to each other are rotatably installed with evenly arranged rollers 320.

[0037] See also Figure 1 , Figure 6 , Figure 7 , Figure 8 and Fig. 9A control component for controlling the stripping length and stripping depth is arranged on the left side of the vertical plate 31. The control component includes a mounting plate installed at the lower end of the outer ring surface of the annular sleeve 311 and opposite to the stripping knife 313. A threaded telescopic rod 322 is installed on the left end of the mounting plate. A limit plate 323 is rotatably installed on the telescopic end of the threaded telescopic rod 322. A guide telescopic rod 324 is connected between the limit plate 323 and the annular surface at the left end of the annular sleeve 311. An adjustment plate 325 located on the left side of the electric push rod 312 is installed on the upper end of the outer ring surface of the annular sleeve 311. The right end of the adjustment plate 325 is provided with The control panel 326 and the adjustment panel 325 are provided with sockets 327 evenly arranged up and down. The control panel 326 is plugged into the corresponding sockets 327 through an insertion rod. A rotating assembly for driving the peeling assembly to rotate is provided on the right side of the vertical plate 31. The rotating assembly includes a gear ring 328. The right end of the annular sleeve 311 passes through the vertical plate 31 and is installed with the gear ring 328. The upper end of the gear ring 328 is meshed with a rotating gear 329 rotatably connected to the vertical plate 31. The right end of the rotating gear 329 is connected to the output shaft of the motor 330. The motor 330 is installed on the right end of the vertical plate 31 through a support.

[0038] During operation: before placing the cable, first adjust the length of subsequent cable stripping according to the depth of the slot inside the terminal. Specifically: rotate the threaded telescopic rod 322 to move the limit plate 323 to the left and stretch the guide telescopic rod 324, and ensure that the distance between the right end face of the limit plate 323 and the left end face of the mounting plate is the same as the depth of the slot, and the mounting plate and the stripping knife 313 are relative to each other, so that the stripping knife 313 is in an accurate and appropriate cutting position. Controlling the length of cable stripping by the limit plate 323 is conducive to the subsequent exposed wire harness conductor being fully inserted into the slot inside the terminal, avoiding the wire harness conductor being too long and remaining outside the terminal, affecting normal use and safety, and also preventing the wire harness conductor inserted into the terminal from having connectivity due to insufficient length. The problems of poor quality and low stability can be solved; the cutting depth of the subsequent stripping knife 313 can be adjusted according to the thickness of the cable skin. Specifically, the control plate 326 can be moved up and down along the adjustment plate 325, and it can be ensured that the distance between the connecting plate and the control plate 326 is the same as the thickness of the cable skin. After the control plate 326 is adjusted to a suitable position, the control plate 326 can be fixed on the adjustment plate 325 by the cooperation between the plug rod and the socket 327. The control plate 326 is used to limit the distance that the connecting plate moves toward the cable, and then the depth of the stripping knife 313 cutting the cable skin can be controlled, which can ensure that the cable skin is fully and effectively cut, facilitating the smooth removal of the subsequent cable skin, and can also avoid excessive cutting of the stripping knife 313 and damage to the wire harness conductor, thereby ensuring the quality of the wire harness conductor.

[0039] In the process of placing the cable, the left end of the cable can be pulled from right to left through the vertical plate 31 and the annular sleeve 311 until the left end of the cable conflicts with the limiting plate 323. At this time, the length of the cable between the stripping knife 313 and the limiting plate 323 is just the required stripping length. In the process of the cable passing through the annular sleeve 311, the cable can also be passed between the upper and lower arc-shaped pressing plates 315 and between the front and rear arc-shaped pushing plates 314 in sequence. The upper and lower arc-shaped pressing plates 315 and the front and rear arc-shaped pushing plates 314 can all pass through the corresponding pushing columns The cooperation between 316 and the connecting spring and the baffle 317 elastically presses the cable, and the upper and lower arc-shaped pressure plates 315 press against the right side of the cable skin cutting position, and the front and rear arc-shaped push plates 314 press against the left side of the cable skin cutting position. The cooperation between the arc-shaped pressure plate 315 and the arc-shaped push plate 314 can press and limit the cable in a circumferential direction, which can not only increase the fulcrum of the cable, further improve the stability of the cable, and ensure the smooth stripping operation, but also ensure the neatness and straightness of the conductor of the harness during the cable skin cutting process.

[0040] After the cable is fixed, the electric push rod 312 can drive the stripping knife 313 to move downward along the annular sleeve 311 through the connecting plate and gradually cut into the cable skin until the connecting plate contacts the control plate 326. At this time, the stripping knife 313 just fully cuts into the cable skin and does not contact the wire harness conductor. Then, the motor 330 can drive the rotating gear 329 to rotate. The rotating gear 329 drives the annular sleeve 311, the stripping assembly and the control assembly to rotate synchronously around the cable for one circle through the gear ring 328. During this process, the stripping knife 313 can perform circumferential cutting on the cable skin so that the cable skin to be stripped is completely cut off. The arc pressure plate 315 and the arc push plate 314 both rotate synchronously with the annular sleeve 311 around the cable and continue to perform circumferential pressure and support on the cable. Then the electric The movable push rod 312 can push the stripping knife 313 upward and reset through the connecting plate until the stripping knife 313 is away from the cable, and then the electric push rod 312 can continue to push the connecting plate and the stripping knife 313 upward, and the connecting plate drives the corresponding baffle 317 and the pushing column 316 to move synchronously in the direction of the axis of the annular sleeve 311 through the connecting rods 319 on its front and rear sides, and the pushing column 316 drives the corresponding arc-shaped push plate 314 to further press against the cable skin to be stripped by compressing the connecting spring, and the arc-shaped push plate 314 presses against the cable through the evenly arranged rollers 320. The evenly arranged rollers 320 not only help the arc-shaped push plate 314 to rotate circumferentially to press the cable, but also increase the axial friction between the arc-shaped push plate 314 and the cable skin, ensuring that the cable skin can be smoothly separated from the wiring harness conductor later.

[0042] See also Figure 1 , Figure 2 , Figure 6 , Fig. 9 and Fig.10The movable plate 32 is provided with a driving assembly for driving the peeling assembly to move up and down, and the driving assembly includes a top plate 351 installed on the upper end of the vertical plate 31 and located above the clamping assembly. The upper end of the movable plate 32 is provided with two vertical guide rails 352 located on the right side of the vertical plate 31 and arranged front and back and connected to the top plate 351 for sliding up and down. An electric slider fixedly connected to the top plate 351 is slidably installed on the vertical guide rails 352. Side panels are installed on the front and back sides of the top plate 351. Support rods 354 connected to the side panels for sliding up and down are installed at the positions corresponding to the side panels on the upper end of the processing table 1 for sliding left and right. The support rods 354 are connected to the vertical guide rails 352. A sealing plate located above the top plate 351 is connected between the upper ends of the processing table 1, and a linkage assembly for driving the movable frame 22, the peeling assembly and the tightening assembly to move left and right is arranged on the upper end of the processing table 1, and the linkage assembly includes a transverse guide rail 355 installed on the upper end of the processing table 1, and an electric slide plate 356 fixedly connected to the movable plate 32 is slidably installed on the transverse guide rail 355, and an automatic push rod 357 located on the front side of the movable frame 22 and fixedly connected to the movable frame 22 at the pushing end is installed on the upper end of the processing table 1, guide blocks are installed on the front and rear sides of the arc frame 21, and a guide column 358 slidably connected to the corresponding guide block left and right is installed on the left end of the movable frame 22.

[0043] During operation: after the front and rear arc-shaped push plates 314 are pressed against the cable segment on the left side of the incision, the electric slide plate 356 can drive the movable plate 32, the clamping assembly, the driving assembly and the stripping assembly to move to the left as a whole along the transverse guide rail 355. At the same time, the stripping assembly can also be controlled to rotate by the rotating assembly. The front and rear arc-shaped push plates 314 can drive the cable skin on the left side of the incision to move to the left while rotating through the evenly arranged rollers 320 until the cable skin is completely rotated out of the wire harness conductor, exposing the wire harness conductor. Then the stripped cable skin can be manually removed from the stripping assembly, and the electric slide plate 356 continues to drive the stripping assembly and the clamping assembly to the left along the transverse guide rail 355. The stripping assembly moves until it moves away from the left end of the cable, and then the front and rear electric sliders can simultaneously drive the top plate 351 to move upward along the corresponding vertical guide rails 352 until the top plate 351 drives the vertical plate 31 and the stripping assembly to move away from the cable as a whole. When the stripping assembly moves to the left, the top plate 351 can drive the support rod 354 to move synchronously along the processing table 1 through the side plates on its front and rear sides. When the stripping assembly moves upward, the top plate 351 can move synchronously upward along the corresponding support rod 354 through the side plates on its front and rear sides. The cooperation between the support rod 354 and the side plates can support and guide the movement of the stripping assembly to ensure the stability of the stripping assembly during stripping and movement.

[0044] During the left movement of the peeling assembly, the moving plate 32 can drive the vertical plate 335, the vertical rod, the clamping assembly and the moving assembly to move synchronously as a whole through the inner plate 341, and the moving gear 338 gradually meshes with the fixed rack 339 on the moving frame 22. Since the moving frame 22 is in a stationary state at this time, the moving gear 338 can drive the connecting gear 337 to rotate counterclockwise synchronously, and the connecting gear 337 can drive the vertical racks 336 on the left and right sides thereof to move synchronously in the opposite direction along the vertical plate 335. The upper rectangular plate 334 and the arc-shaped matching plate 331 move downward along the vertical rod, and the lower rectangular plate 334 and the arc-shaped matching plate 331 move downward along the vertical rod. The mating plate 331 moves upward along the vertical rod until the upper and lower arc-shaped mating plates 331 are snap-fitted, and the snap-fitting of the upper and lower arc-shaped mating plates 331 is carried out simultaneously with the stripping of the cable skin. When the stripping assembly moves away from the left end of the cable, the upper and lower arc-shaped mating plates 331 can just compress the auxiliary spring to enable the arc-shaped auxiliary plate 346 to limit and tighten the wiring harness conductor from the upper and lower sides, which can effectively prevent the wiring harness conductor from opening outward after stripping, and ensure that the wiring harness conductor can be smoothly and efficiently inserted into the terminal, and the arc-shaped mating plate 331 is a distance away from the left and right ends of the exposed wiring harness conductor.

[0045] Then, the moving plate 32 and the clamping assembly can continue to be driven to move to the left by the electric slide plate 356. At the same time, the moving frame 22, the clamping member 2 and the cable in the fixed state can be driven to move to the left synchronously by the automatic push rod 357. The guide columns 358 on the front and rear sides of the moving frame 22 can move to the left along the corresponding guide blocks to guide the left movement of the moving frame 22 and the cable. In this process, the left end of the wire harness conductor in the clamping state is gradually inserted into the right end of the terminal, the arc-shaped matching plate 331 gradually contacts the right end of the terminal, and the alignment rods 332 at the left ends of the upper and lower arc-shaped matching plates 331 are gradually inserted into the corresponding alignment holes 333 at the right ends of the front and rear arc-shaped clamping plates 214. The left movement of the clamping assembly and the wire harness conductor can be guided by the cooperation between the alignment rods 332 and the alignment holes 333. , ensuring that the wiring harness conductor is accurately inserted into the slot at the right end of the terminal. In addition, the side rod 344 on the front side of the vertical plate 335 gradually contacts the fixed column 345 at the right end of the arc frame 21, and the side rod 344 is pressed to push the vertical plate 335 to move. The vertical plate 335 drives the inner plate 341 to compress the spring rod 342 along the installation groove, and the clamping assembly and the moving assembly as a whole move to the right synchronously with the inner plate 341. The moving frame 22 drives the cable to move to the left relative to the clamping assembly through the second clamping member, and the cable at the right end of the exposed wiring harness conductor can enter the arc-shaped moving groove on the right side of the arc-shaped matching plate 331. At this time, the moving frame 22 and the fixed rack 339 move to the left, and the moving gear 338 in the moving assembly moves to the right, so the moving gear 338 remains in meshing with the fixed rack 339 and rotates clockwise.

[0046] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 A rotating assembly for controlling the rotation of the arc plate 211 is provided at the upper end of the processing table 1, and the rotating assembly includes an arc rack 111 installed on the inner side of the arc plate 211, and an adjusting gear 112 is meshed on the upper end of the arc rack 111. A circular through groove is opened at the center of the adjusting gear 112, and a spiral groove 113 is opened on the inner wall of the circular through groove. A rotating cylinder rotatably connected to the processing table 1 is installed on the left end of the adjusting gear 112, and a support plate 114 slidably connected to the processing table 1 left and right is provided on the right side of the arc frame 21, and a telescopic spring 115 is connected between the support plate 114 and the arc frame 21, and a moving rod 116 matching with the circular through groove is installed on the left end of the arc frame 21, and a matching column matching with the spiral groove 113 is installed on the left end of the moving rod 116, and L-shaped push plates 117 corresponding to the ends of the support plate 114 are installed on the front and rear sides of the moving frame 22.

[0047] See also Figure 1-Figure 10 , when working: under the action of the moving component, the upper and lower arc-shaped matching plates 331 gradually move synchronously in the opposite direction to move away from the harness conductor, but the arc-shaped auxiliary plate 346 always maintains the elastic limit of the harness conductor. At this time, there is still a small section of the harness conductor that has not been fully inserted into the slot at the right end of the terminal. Then the moving frame 22 and the cable can continue to move left, and the moving frame 22 drives the L-shaped push plates 117 on the front and rear sides to press the support plate 114 to the left. The support plate 114 compresses the telescopic spring 115 and drives the moving rod 116 to move to the left along the processing table 1. When the moving rod 116 moves to the left, the matching column gradually matches with the spiral groove 113 on the adjusting gear 112. Under the cooperation of the moving rod 116, the matching column and the spiral groove 113, the adjusting gear 112 gradually drives the rotating The movable cylinder rotates, and the arc rack 111 drives the arc plate 211 to rotate synchronously along the arc frame 21 with the adjusting gear 112. The arc plate 211 drives the clamping part 1 to rotate synchronously with the terminal in the fixed state through the fixed plate 212. The terminal rotates while the cable moves to the left until the wiring harness conductor is fully and completely screwed into the terminal. Then, the arc clamping plates 214 on the front and rear sides can be controlled by a two-way electric telescopic rod 1 215 to continue to move synchronously towards each other, and the arc clamping plates 214 on the rear side of the clamping plate 217 move forward synchronously and gradually press the rotating plate 218, so that the rotating plate 218 rotates forward around the torsion spring axis. At this time, the arc clamping plates 214 on the front and rear sides can press the terminals with the wiring harness conductors inserted to ensure a tighter and more stable connection between the wiring harness conductors and the terminals.

[0048] After completing the connection between the cable and the terminal, the clamping and fixing of the terminal and the cable by the clamping parts 1 and 2 can be released in the opposite manner as described above. The terminal is still located at the upper end of the fixed plate 212 under the action of the positioning column, and the cable is always located at the upper end of the movable frame 22. Then, the movable frame 22 can be pushed to the right by the automatic push rod 357, and the support plate 114 drives the movable rod 116 and the matching column to move right synchronously and make the fixed plate 212, the clamping part 1 and the terminal rotate and reset to a horizontal state. While the movable frame 22 moves to the right, the clamping assembly can be moved to the right. With the cooperation of the fixed rack 339 and the moving gear 338, the upper and lower arc-shaped matching plates 331 gradually move in the opposite direction to the reset state. Then the connected cable and terminal can be removed, and then the stripping assembly can be moved down to reset. Finally, the clamping assembly, the stripping assembly and the movable frame 22 can be moved right as a whole to reset.
