Description

Technical Field

[0001] The present invention relates to the technical field of automobile wiring harness terminals, and in particular to a wiring harness terminal correction device for new energy vehicles. Background Art

[0002] The driving power and control system inside the new energy vehicle transmits power and electrical signals through wires. In order to facilitate modular assembly and later disassembly and maintenance, the wiring harness terminal is connected to the end of the wire. The wiring harness terminal can be quickly connected and disconnected by plugging and unplugging, realizing modular assembly and convenient disassembly and maintenance in the later stage. The wiring harness terminal generally consists of a shell and a pin. The shell is provided with a snap-fit ​​structure to realize the snap-fit ​​fixation of the male and female shells. The same is true for the pin, which is divided into male and female heads. The end of the male head is inserted into the end of the female head to realize electrical connection.

[0048] In this embodiment, the first industrial camera 28 and the second industrial camera 31 are both Hangzhou Weitu Vieworks industrial cameras VC-25MX2-M150 in the prior art.

[0049] In the present invention, when the user uses the device, he manually takes the wiring harness so that one of the terminals with multiple pins inside the wiring harness is located between the two first clamps 6, and the wiring harness terminal is clamped and fixed by the two first clamps 6. At this time, the rotating plate 24 is controlled to rotate upward, driving the two first industrial cameras 28 to rotate to the bottom, so that it can automatically identify and detect the wiring harness terminal below. If the surface of the wiring harness terminal is severely damaged or the multiple pins inside are greatly deformed, the two first clamps 6 can be directly controlled to move in opposite directions. After the wiring harness terminal loses the clamping and fixation of the two first clamps 6, it can fall downward and be discharged, and the subsequent wiring harness terminals to be corrected can continue to be detected.

[0050] If the wiring harness terminal passes the inspection of the two first industrial cameras 28 and is qualified, that is, the wiring harness terminal shell is not damaged and only a small number of pins inside are greatly deformed, the third slider 19 can be controlled to move together with the multiple components below inside the third slide groove 15, and the rotating plate 24 can be controlled to drive the two clamping plates 8 to rotate downward and be in an inclined state. With the help of the telescopic end of the first electric telescopic rod 22 to extend downward, the two clamping plates 8 are driven to extend into the interior of the wiring harness terminal and clamp the pins with larger deformation. With the help of the first moving block 21 to move back and forth inside the first groove 20, the pins with larger deformation are driven to be straightened, so that the pins with larger deformation are located inside the wiring harness terminal and are corrected upward to a smaller deformation state through the cooperation of the two clamping plates 8, so as to facilitate the subsequent second correction mechanism to correct multiple pins inside the wiring harness terminal at the same time, and avoid the problem that the pins are greatly deformed and cannot be automatically corrected by directly using the second correction mechanism.

[0051] If some wiring harness terminals that have been welded to the automobile wiring harness need to be corrected, the pins with larger deformation inside the wiring harness terminal can be pre-corrected as mentioned above. At this time, the first electric telescopic rod 22 can be controlled to move upward from the inside of the wiring harness terminal, and the two clamping plates 8 can be driven to move to the maximum distance in the direction away from each other by means of the first double-headed screw 27. At this time, the telescopic end of the first electric telescopic rod 22 is controlled to extend downward again, driving the two clamping plates 8 to be located at the two ends of the wiring harness terminal respectively, and the two clamping plates 8 are controlled to move in the direction of approaching each other, so that the two clamping plates 8 can directly clamp and fix the wiring harness terminal, and then the two first clamping blocks 6 are controlled to release the clamping effect on the wiring harness terminal. The two first sliders 16 are controlled to move downward inside the corresponding first slide grooves 4, driving the two first clamping blocks 6 to move downward together to a position close to the other terminal of the wiring harness. After the other terminal of the wiring harness is clamped and fixed by the two first clamping blocks 6, the telescopic end of the first electric telescopic rod 22 can be controlled to retract upward, and the wiring harness as a whole can be pulled and tested, so that the strength of the automobile wiring harness that needs to be corrected can be automatically tested, avoiding the automobile wiring harness with quality problems from taking a long time to correct its terminals, resulting in a waste of time, which can indirectly help the correction efficiency of the wiring harness terminals and the subsequent qualified rate of the wiring harness terminals.

[0052] If there is a problem with the wiring harness after the quality test, the two clamps 8 and the two first clamps 6 can be controlled at the same time to loosen the clamping of the two terminals, so that they can automatically fall down; if there is no problem with the wiring harness after the quality test, the two first clamps 6 can be controlled to reset upward, and the two clamps 8 can be controlled to move downward and reset, so that the two first clamps 6 can clamp and fix the wiring harness terminals again, and then the rotating plate 24 is controlled to rotate upward, and the dust collector head 25 is driven to rotate to the bottom end, and the telescopic end of the first electric telescopic rod 22 is used to drive the dust collector head 25 to tightly abut against the top of the wiring harness terminal. At this time, the dust collector head 25 can automatically remove a small amount of impurities attached to the inside of the wiring harness terminal, which is convenient for the subsequent correction of multiple pins inside the wiring harness terminal and the automatic detection of the corrected pins; the above-mentioned dust removal treatment of the terminals that have been welded to the end of the automobile wiring harness is also applicable to the dust removal of terminals that have not been welded to the automobile wiring harness.

[0053] After cleaning the impurities inside the wiring harness terminal, the wiring harness terminal can be clamped and fixed again with the help of the two clamping plates 8, and as the third slider 19 moves in the third slide groove 15 toward the second clamping mechanism, it is necessary to control the adaptive extension of the telescopic end of the first electric telescopic rod 22 to ensure that the wiring harness terminal can move downward inside the two guide plates 3. After the third slider 19 moves to the bottom of the two guide plates 3, the two clamping plates 8 are controlled to release the clamping limit of the wiring harness terminal, so that the wiring harness terminal moves to the inside of the second clamping mechanism, and the wiring harness terminal is clamped with the help of the two second clamping blocks 29 of the second clamping mechanism. The terminal is clamped and fixed, and then the telescopic end of the third electric telescopic rod 9 is controlled to extend downward, driving the sleeve plate 12 to be sleeved on the surface of the wiring harness terminal, so that the three groups of correction plates 36 are respectively moved to the two sides of the multiple pins inside the wiring harness terminal, and the three groups of second double-headed screws 39 are controlled to rotate, driving the three groups of correction plates 36 to move in a direction close to each other, and clamping and correcting the multiple metal plates at the corresponding positions of the wiring harness terminal are processed, and the metal plates with smaller deformation and those corrected by the first correction mechanism are processed for the second time together. The entire correction of the wiring harness terminal has a high degree of automation, and does not require manual operation that takes a lot of time.

[0054] Since heating blocks are preset inside the multiple groups of correction plates 36, the surfaces of the multiple groups of correction plates 36 have a relatively high temperature, and detachable cleaning pads are preset at the bottom ends of the multiple groups of correction plates 36. When it is found that a small amount of impurities such as oil and dirt are attached to the surface of the pins and are difficult to be automatically sucked away by the vacuum cleaner 25, the multiple groups of correction plates 36 can correct the pins while also introducing the high temperature of the correction plates 36 themselves into the inside of the pins, so that the oil and dirt or other impurities attached to the surface are affected by the high temperature and melt and flow downward to the inner bottom surface of the wiring harness terminal. At this time, the cleaning pad at the bottom end of the correction plate 36 can contact the inner bottom surface of the wiring harness terminal while adsorbing and removing such impurities, and as the telescopic end of the third electric telescopic rod 9 contracts upward, the impurities remaining on the surface of the pins are wiped off, thereby improving the cleanliness of the inside of the wiring harness terminal and facilitating the subsequent use of the wiring harness terminal.

[0055] Moreover, since the strength of the pins inside the wiring harness terminal will be affected to a certain extent after the correction treatment, after the correction work of the metal plates by multiple sets of correction plates 36 is completed, the telescopic end of the third electric telescopic rod 9 can be controlled to retract upward, driving the multiple sets of correction plates 36 to move upward to a position corresponding to the top of the pins. At this time, the multiple sets of correction plates 36 move in a direction close to each other, and the multiple pins inside the wiring harness terminal can be clamped and fixed, and the second clamping mechanism is used to clamp and fix the wiring harness terminal shell. The telescopic end of the third electric telescopic rod 9 continues to retract upward, and multiple pins can be pulled upward at the same time, so that the quality of the corrected pins can be automatically tested, which is convenient for selecting wiring harness terminals that meet quality requirements from the corrected wiring harness terminals, thereby improving the utilization rate of the corrected wiring harness terminals.

[0056] Since the plastic shells of a small number of wiring harness terminals have slight deformations, the high temperature generated by the multiple correction plates 36 themselves can simultaneously heat and soften the plastic shells of the wiring harness terminals after entering the interior of the wiring harness terminals, and after the sleeve plate 12 is sleeved on the surface of the plastic shell of the wiring harness terminals, it has a limiting effect on the wiring harness terminals. Multiple sets of correction plates 36 can be driven to move back and forth inside the wiring harness terminals with the help of the corresponding two second double-headed screws 39 to shape the softened plastic shell of the wiring harness terminals, so that the second correction mechanism can also have a correction effect on the plastic shell of the wiring harness terminal at the same time, further improving the applicability of the device.

[0057] After the wiring harness terminal correction work is completed, the two third moving blocks 34 can be controlled to drive the sleeve plate 12 to move in a direction away from the multiple through slots 33, so that the multiple through slots 33 are located directly above the wiring harness terminal. With the help of the telescopic end of the third electric telescopic rod 9 extending downward, the second rectangular plate 11 is driven to move downward until it abuts against the top of the wiring harness terminal. At this time, the multiple second industrial cameras 31 can detect and identify whether the positions of the multiple pins inside the wiring harness terminal correspond to the multiple through slots 33, so that the correction quality of the multiple pins inside the wiring harness terminal and the plastic shell can be automatically detected without manual detection, thereby further improving the degree of automation of the entire wiring harness terminal correction work.

[0058] After the wiring harness terminals are inspected with the help of multiple second industrial cameras 31, the sleeve plate 12 can be controlled to move and reset, and the telescopic end of the third electric telescopic rod 9 can be extended downward so that the sleeve plate 12 can be again sleeved on the surface of the wiring harness terminals. At this time, after the limit plate 14 is controlled to rotate to a position in the same line with one of the guide plates 3, as the sleeve plate 12 moves under the second rectangular plate 11, the corrected wiring harness terminals are pushed downward from between the two guide plates 3 to achieve the effect of automatic unloading.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification.
