Description

Technical Field

[0001] The invention relates to the technical field of new energy wire harness terminal crimping, and in particular to a new energy wire harness multi-wire crimping terminal machine. Background Art

[0002] New energy wiring harness is a collection of wires and cables that connect various components of new energy vehicles. Before it is put into use, it is usually necessary to crimp and install terminals for connecting wiring harnesses and components on the new energy wiring harness through a terminal machine, and install and position multiple wiring harness terminals at the same time in a terminal shell used to protect the terminals, so as to facilitate the unified installation and connection of multiple new energy wiring harnesses with the corresponding components through the terminal shell.

[0003] In the prior art, when crimping new energy wiring harnesses and terminals through a terminal machine, multiple wiring harnesses are usually first synchronously loaded to a specific position through a loading device, and then the wiring harnesses are continuously adjusted and aligned through the loading device to cooperate with the terminal machine to crimp the terminals of each wiring harness in turn, and then the multiple groups of crimped wiring harness terminals are uniformly cut and unloaded, and finally the formed wiring harness terminals are picked up by manual or automatic grippers and plugged and installed in the corresponding terminal shells in turn.

[0004] However, the traditional terminal machine has the following problems in the way it crimps and processes new energy wiring harnesses and terminals: 1. Since the existing terminal machines are usually unable to crimp multiple groups of wiring harnesses and terminals simultaneously, and the feeding device needs to be constantly coordinated and adjusted when crimping in sequence, when crimping terminals on large quantities of wiring harnesses, the overall operation steps of the wiring harness crimping terminals will be more and the overall crimping efficiency will be lower. It will also lead to a higher overall usage frequency of the single crimping head on the terminal machine, resulting in a higher overall wear and replacement frequency of the crimping head; 2. Since the existing terminal machines are usually unable to directly plug and install the crimped wiring harness terminals with the corresponding terminal shells, it is necessary to add operating equipment and manual operations to plug and install the crimped wiring harness terminals into the terminal shells in sequence, resulting in a large number of equipment required for the overall processing and production of the wiring harness terminals, high space usage costs and equipment maintenance costs, and low overall efficiency of wiring harness terminal plugging. In addition, the operation process continuity between the wiring harness crimping installation terminals and the terminal shell plug-in installation wiring harness terminals is poor, and there are more operation steps, which leads to low efficiency in the overall processing and production of the wiring harness terminals.

[0043] Under the elastic action of spring rod four 333 and spring rod five 335 respectively, wedge block two 334 and wedge block three 336 can be respectively engaged with the rectangular grooves at the corresponding positions on terminal row 337, so that terminal row 337 can be limited by the cooperation of wedge block two 334 and wedge block three 336 to prevent terminal row 337 from retreating to the left or shifting forward and backward, and the terminal row 337 can be limited up and down by the cooperation of L-shaped pressure plate 324 with offset platform 322, loading platform 321 and positioning platform 326; when the metal row sheet on terminal row 337 moves to the right relative to wedge block two 334 or wedge block three 336, wedge block two 334 or wedge block three 336 will drive spring rod four 333 or spring rod five 335 to make way upwards under the pressure cooperation between the left inclined surface and the corresponding rectangular groove, so as to ensure that terminal row 337 can move stably to the right.

[0044] The spring rod four 333 and the wedge block two 334 can be driven by the electric slider two 332 to move from the left end of the guide rail two 331 to the right end, and the wedge block two 334 then cooperates with the rectangular groove at the corresponding position on the terminal row 337 through the right plane, thereby driving the terminal row 337 to move to the right synchronously for loading, and the wedge block three 336 then moves upward synchronously to make way under the pressure of the metal row and the rectangular groove until the terminals to be crimped are loaded between the two adjacent L-shaped pressure plates 324, that is, each positioning sleeve 231 and the front end of the wiring harness inside it are aligned with the terminals to be crimped, at this time, the wedge block three 336 can be engaged with the rectangular groove at the corresponding position under the action of the spring rod five 335, and then driven by the electric slider two 332 The wedge block 2 334 moves to the left to reset, and then moves upward to make way under the pressure of the metal sheet and the rectangular groove, and at this time the terminal row 337 cannot retreat to the left under the limitation of the wedge block three 336, until the wedge block 2 334 moves to the leftmost end of the guide rail 2 331 again, and under the action of the spring rod four 333, the wedge block 2 334 is just engaged with the rectangular groove at the corresponding position to ensure that the terminal row 337 can be continuously fed and limited. The above-mentioned operation method can realize the one-time synchronous feeding and positioning of multiple terminals to be crimped, so that the front end of each wiring harness in the positioning sleeve 231 is aligned with the terminal to be crimped, so as to ensure that multiple groups of wiring harnesses and terminals can be crimped and installed synchronously in the future.

[0045] See also Figure 2 and Figure 5 The crimping assembly 34 includes a plurality of docking pressure columns 341 that are evenly fixed on the lower side of the lifting platform 316 and press-fit with the L-shaped pressure plate 324 in a one-to-one manner.

Each group of crimping joints is composed of a wire core crimping head 342 and a wire harness crimping head 343 distributed front and back.

[0046] When multiple groups of wire harnesses and terminals are to be crimped and installed synchronously, the terminal row 337 is first loaded through the wedge block 234, so that each positioning sleeve 231 and the front end of the wire harness inside it are aligned with the terminal to be crimped, and then the electric slider 212 drives all the positioning sleeves 231 and the wire harness inside them to move forward a certain distance synchronously until the wire harness and the exposed metal wire at the front end move to the corresponding position on the corresponding terminal, and then the lifting platform 2 316 is driven to move downward continuously through the hydraulic cylinder 2 315, and the docking pressure column 341 and the crimping head move downward synchronously until the wire core pressure head 342 and the wire harness pressure head 343 cooperate with the corresponding support platform 325, so that the corresponding positions on the terminal are crimped and installed with the metal wire and the end of the wire harness respectively. At the same time, during the crimping process between the crimping head and the supporting platform 325, the docking pressure column 341 will synchronously press the corresponding L-shaped pressure plate 324 downward, so that the L-shaped pressure plate 324 and the offset platform 322 are moved downward by a certain distance relative to the supporting platform 325 through the spring rod three 323, until the connecting piece used to connect the terminal and the metal sheet is completely broken due to the dislocation, thereby separating the terminal from the metal sheet. The above-mentioned operation method can simultaneously crimp terminals of multiple new energy wiring harnesses, thereby not only greatly reducing the operating steps of the existing terminal machine and feeding device, improving the overall efficiency of wiring harness terminal crimping, but also greatly reducing the frequency of use of a single crimping head, thereby reducing the overall wear and replacement frequency of the crimping head, and at the same time reducing the overall production cost.

[0049] When multiple crimped wiring harness terminals are to be synchronously aligned and inserted into the corresponding terminal shells, the corresponding terminal shells are first loaded into the loading rack 525 through the loading equipment, and the jacks on the terminal shells are facing backwards. The hydraulic cylinder 311 is then used to drive the lifting platform 312 to move downward to make way, and the hydraulic cylinder 315 is used to drive the lifting platform 316 to move upward to reset. Then, the electric slider 212 is used to drive all the positioning sleeves 231 and the wiring harnesses with terminals crimped and installed inside to continue to move forward synchronously. The wedge block 236 then cooperates with the inclined surface of the rear end of the corresponding L-shaped limit plate 521 in the docking mechanism 5, thereby driving the corresponding positioning sleeve 231 to move a specific distance in the direction of the connecting column 224 until the front end of the wiring harness with the terminals crimped and installed is aligned with the front upper The sockets at corresponding positions on the terminal shell in the rack 525 are aligned, and with the continuous driving of the electric slider 212, the positioning sleeve 231 drives the terminal crimped and installed on the wiring harness to be inserted into the corresponding socket, and the tightening sleeve 232 then pushes the rear end of the corresponding terminal by tightening, thereby ensuring that the terminal can be completely and stably inserted and positioned in the corresponding socket. The above-mentioned operation method can realize that after the wiring harness terminal is crimped and formed, the formed multiple wiring harness terminals can be synchronously and stably inserted and installed in the terminal shell, thereby not only improving the overall efficiency of the insertion and installation of the wiring harness terminal and the terminal shell, but also reducing the number of equipment required for the overall processing and production of the wiring harness terminal, while improving the continuity of the operation process between the crimped installation terminal of the wiring harness and the plug-in installation of the formed wiring harness terminal of the terminal shell.

[0050] See also Figure 1 and Figure 2 The peeling mechanism 4 includes an electric push rod 41 fixedly arranged on the upper side of the fixed platform 314 and located at the rear side of the hydraulic cylinder 315. The telescopic end of the electric push rod 41 is provided with a driving component 42 that moves up and down, and the driving component 42 is provided with a peeling component 43.

[0051] See also Figure 2 and Figure 8 The driving assembly 42 includes a U-shaped connecting plate 421 fixedly arranged on the telescopic end of the electric push rod 41 and with its opening facing downward. A lifting frame 422 is fixedly arranged on the lower side of the U-shaped connecting plate 421. The lifting frame 422 is evenly provided with multiple straight grooves 423 that penetrate up and down, extend left and right, and correspond to the positioning sleeves 231 one by one. A hydraulic cylinder three 424 located on the left side of the straight groove 423 is fixedly arranged on the upper side of the lifting frame 422 through a support two.

[0052] See also Figure 2 and Figure 8The peeling assembly 43 includes multiple groups of peeling knife groups evenly arranged on the left and right sides of the lower side of the lifting frame 422 and corresponding to the linear grooves 423 one by one, each group of peeling knife groups consists of a cutting knife group and a ring cutting knife group arranged front and back, wherein the cutting knife group consists of a cutting blade 431 that is symmetrical on the left and right, and the ring cutting knife group consists of a ring cutting blade 432 that is symmetrical on the left and right, and a connecting plate 1 433 is fixedly arranged on the upper ends of the corresponding cutting blades 431 and the ring cutting blades 432 distributed front and back on the left side of each peeling knife group, and the upper ends of the connecting plate 1 433 are fixedly connected to the lifting frame 422 through a rod 1, and the upper ends of the corresponding cutting blades 431 and the ring cutting blades 432 distributed front and back on the right side are fixedly arranged with a connecting plate 2 434, and a sliding rod 435 that is slidably connected to the corresponding linear groove 423 is fixedly arranged on the upper side of the connecting plate 2 434, and a connecting plate 3 436 that moves left and right and is fixedly connected to the telescopic end of the hydraulic cylinder 3 424 is fixedly arranged on the upper ends of the sliding rods 435 evenly distributed on the left and right.

[0053] When all the wiring harness terminals in the positioning sleeve 231 are inserted and positioned in the terminal shell, the positioning sleeve 231 is first driven to move backward by the electric slider 212 until the locking sleeve 232 moves to the rear side of the corresponding stripping knife group. Since the terminal and the terminal shell are clamped and positioned together and cannot move backward, the positioning sleeve 231 and the pressing block 234 will move backward along the corresponding wiring harness for a specific distance synchronously. At this time, the lifting frame 422 is driven downward by the electric push rod 41 until each stripping knife group is respectively docked with the corresponding wiring harness, and then the hydraulic cylinder 424 drives the connecting plate 436 to the left, so that the connecting plate 436 drives the cutting blade 431 and the circular cutting blade 432 on the right side of each stripping knife group through the sliding rod 435 to move to the left along the straight groove 423 and cooperate with the cutting blade 431 and the circular cutting blade 432 on the left side, so that not only can the corresponding wiring harness be cut into two sections, front and back, by the cutting knife group, but also the rear section can be cut into two sections, The insulating rubber ring at the front end of the first segment of the wiring harness is cut off, and at this time, the positioning sleeve 231 is driven to move backward by the electric slider 1 212, and the pressure block 234 is then pressed by the spring rod 233 to press the corresponding rear segment of the wiring harness and drive it to move backward synchronously until the metal wire at the front end of the rear segment of the wiring harness is pulled out of the cut rubber ring and is exposed, so as to facilitate the crimping of the next group of terminals of the rear segment of the wiring harness. At the same time, the terminal shell with the wiring harness terminals installed in the loading rack 525 is driven forward by the electric slider 3 524 until the terminal shell is no longer limited by the right side baffle plate 522, so that the terminal shell can be pushed to the right through the opening on the right side of the loading rack 525 for unloading by the electric push rod 2 526. The above-mentioned operation method can not only realize the repeated crimping operation of multiple groups of wiring harnesses and terminals, but also can quickly unload the terminal shell after the multiple groups of crimped wiring harness terminals are installed in the terminal shell, thereby ensuring the overall processing and production efficiency of the wiring harness terminals.
