[0030] The utility model is further described below in conjunction with embodiments and drawings.

[0031] like Figure 1 As shown, an automatic tooling device for a high-voltage wire harness tail cover comprises a mechanical clamp 1 and a high-voltage wire harness clamping assembly A and a tail cover tooling assembly B arranged at the front end of the mechanical clamp 1, wherein the mechanical clamp 1 is used to clamp the tail cover part b, the high-voltage wire harness clamping assembly A and the tail cover tooling assembly B are arranged opposite to each other, the high-voltage wire harness clamping assembly A is used to clamp and fix the high-voltage wire harness a, and the tail cover tooling assembly B is used to tool the tail cover part b on the facing high-voltage wire harness a. The tail cover part b clamped by the mechanical clamp 1 can be placed on the tail cover tooling assembly B, and tooled on the high-voltage wire harness a clamped by the high-voltage wire harness clamping assembly A through the tail cover tooling assembly B. An automatic tray replacement assembly C is arranged on the side of the mechanical clamp 1, and the automatic tray replacement assembly C can automatically replace an empty tray and a full tray to ensure that the mechanical clamp 1 can always clamp the tail cover part b in the tray.

[0032] With such a design, the tail cover part b can be clamped by the mechanical gripper 1, and in combination with the high-voltage wire harness clamping component A and the tail cover tooling component B, the tail cover part b can be automatically tooled onto the high-voltage wire harness a, and then in combination with the automatic tray replacement component C, the empty tray can be replaced in time to ensure that the mechanical gripper 1 can grab the tail cover part b and place it on the tail cover tooling component B in time. The entire tooling process has a high degree of mechanization and high tooling efficiency, and the mechanized tooling also ensures product consistency.

[0033] In this embodiment, two groups of automatic tray replacement components C are provided on the left and right sides of the mechanical clamp 1, and each group of automatic tray replacement components C is correspondingly provided with a high-voltage wire harness clamping component A and a tail cover tooling component B, so that two different tail cover parts b can be tooled on the high-voltage wire harness a. In addition, only one set of mechanical clamps 1 can be used to tool the tail cover parts b of the high-voltage wire harness a of two production lines.

[0034] like Figure 2 As shown, a detection element 2 is also provided at the front end of the mechanical gripper 1. The tail cover part b gripped by the mechanical gripper 1 needs to be detected by the detection element 2 before being placed on the tail cover tooling assembly B. In this embodiment, the detection element 2 is selected to detect in real time through CCD visual detection whether the tail cover part b gripped by the mechanical gripper 1 is damaged, thereby ensuring the tooling quality of the tail cover tooling.

[0035] like Figure 3 As shown, the high-voltage wire harness clamping assembly A includes a mounting platform 3 and a clamping claw 4 slidably mounted at the bottom of the mounting platform 3. Specifically, a slide rail 3a is fixedly mounted on the mounting platform 3 by bolts, and a slider 3b is slidably matched on the slide rail 3a. The clamping claw 4 is fixedly mounted on the slider 3b. A first limit block 3c is also fixedly mounted at both ends of the slider 3a, which can ensure that the clamping claw 4 can clamp the high-voltage wire harness a and move it to a specified position to ensure the uniformity of the tooling position. In this embodiment, the sliding of the slider 3b is pneumatically controlled. Similarly, the clamping claw 4 is also pneumatically controlled, and two clamping claws 4 are installed at the lower end of the slider 3b to achieve the simultaneous tooling of the tail cover parts b of the two high-voltage wire harnesses a.

[0036] like Figure 4 and Fig.10 As shown, the tail cover tooling assembly B includes a tooling vertical plate 5 that is slidably arranged forward and backward relative to the high-voltage harness clamping assembly A and a driving assembly 6 that drives the tooling vertical plate 5 to slide. A clamping portion 7 is installed on the top of the tooling vertical plate 5. In this embodiment, the driving assembly 6 is driven by a driving motor. The clamping portion 7 is composed of two symmetrically arranged clamping blocks 7a. Cylinders are installed at the bottom of the two clamping blocks 7a, and the two clamping blocks 7a are fitted together by the cylinders, thereby ensuring that the tail cover part b is fixed, which is convenient for the tooling of the tail cover part b. The fitting surfaces of the two clamping blocks 7a are set to a semicircular concave structure, so as to ensure that a circular through hole can be formed when the two clamping blocks 7a are fitted together, which is convenient for the high-voltage harness a to pass through. A clamping groove 7a1 is also provided on the clamping block 7a, and the clamping groove 7a1 is used to place the tail cover part b, which is convenient for the tooling of the tail cover part b. In this embodiment, two clamping blocks 7 are provided on the top of the tooling vertical plate 5 corresponding to the clamping claws 4, so as to ensure that two high-voltage wire harnesses a can be tooled at the same time.

[0037] For example Figure 5As shown, the tray automatic sliding assembly C includes a conveying assembly 8, on which the first lifting platform 9, the second lifting platform 10 and the third lifting platform 11 are sequentially arranged. The tray can be moved to any lifting platform under the action of the conveying assembly 8, wherein an empty tray storage assembly 12 is arranged on the top of the first lifting platform 9, and the tray lifted by the first lifting platform 9 can be stored at the bottom of the empty tray storage assembly 12, a full tray storage assembly 13 is arranged on the top of the second lifting platform 10, and the tray lifted by the second lifting platform 10 can be stored at the bottom of the full tray storage assembly 13, and a support plate 14 is arranged on the top of the third lifting platform 11, and the tray lifted by the third lifting platform 11 can be against the bottom plate of the support plate 14. In actual use, the installation position of the third lifting platform 11 is closest to the mechanical gripper 1 compared to the first lifting platform 9 and the second lifting platform 10, and the mechanical gripper 1 directly clamps the tail cover part b in the tray lifted by the third lifting platform 11 for tooling.

[0038] For details, please refer to Figure 6 The transmission assembly 8 includes installation vertical plates 8a that are symmetrically distributed on the left and right sides. The top of the inner side of the two installation vertical plates 8a is equipped with a transmission crawler 8b. A synchronization rod 8c is connected between the two sets of transmission crawlers, and the synchronization rod 8c is used to rotate synchronously. A driving motor 8d is also fixedly installed between the two installation vertical plates 8a. The driving motor 8d is used to drive the synchronization rod 8c to rotate, thereby ensuring that the transmission assembly 8 can rotate. In this embodiment, an output wheel 8e is installed at the output end of the driving motor 8d, and a synchronization wheel 8f is mounted on the synchronization rod 8c. The output wheel 8e and the synchronization wheel 8f are synchronously connected through a synchronization belt 8g.

[0039] Please refer to Figure 7 The empty tray storage assembly 12 includes first pillars 12a symmetrically arranged on the top of two mounting plates 8a. Two first pillars 12a are fixedly installed on any mounting plate 8a by bolts. Four first pillars 12a are symmetrically arranged in pairs to form a rectangular frame. The rectangular frame is used to stack empty trays vertically. Each first pillar 12a is provided with a support block 12b on one side close to the conveyor crawler 8b. The empty tray lifted by the first lifting platform 9 can be supported by the support block 12b. For details, please refer to Fig. 9, each support block 12b is provided with a protrusion 12b1 on one side close to the conveyor track 8b, and the top of the protrusion 12b1 is used to support the empty tray. The empty tray lifted by the first lifting platform 9 can force each protrusion 12b1 to rotate toward the outside of the mounting plate 8a. A reset element 12b2 is connected between the support block 12b and the protrusion 12b1. The reset element 12b2 exerts a reset force to ensure that the protrusion 12b1 is in a protruding state, that is, when the first lifting platform 9 lifts the empty tray to exceed the upper end surface of the protrusion 12b1, the reset element 12b2 forces the protrusion 12b1 to rotate to a protruding state, so that the top of the protrusion 12b1 can be used to support the empty tray. With such a design, the entire empty tray storage assembly 12 is made more compact through the method of longitudinal stacking, and the rotating protrusion 12b1 also makes the entire support structure very compact. In order to facilitate the rotation of the protruding portion 12b1, a guiding inclined surface 12b3 is formed at the lower end of the protruding portion 12b1.

[0040] In this embodiment, the empty trays stacked at the empty tray storage assembly 12 are eventually moved manually. In order to prevent the empty tray storage assembly 12 from collapsing due to excessive empty trays stacked therein, a limiting photoelectric 12c is further provided at the upper end of the first pillar 12a.

[0041] Please refer to Figure 8 The full tray storage assembly 13 includes a clamping assembly 13a and a second support 13b symmetrically arranged on the outside of two mounting vertical plates 8a. Two second support pillars 13b are arranged on any mounting vertical plate 8a. Four second support pillars 13b are symmetrically arranged in pairs to form a rectangular frame. The rectangular frame is used to stack full trays. The clamping assembly 13a is used to clamp the stacked full trays. In this embodiment, the two second support pillars 13b on the same mounting vertical plate 8a are symmetrically arranged on the left and right sides of the clamping assembly 13a.

[0042] Specifically, the clamping assembly 13a includes a lifting cylinder 13a1 symmetrically arranged on the outside of the two mounting plates 8a and a clamping cylinder 13a2 fixedly installed on the top of the lifting cylinder 13a1, wherein the lifting cylinder 13a1 is directly used to lift the clamping cylinder 13a2 up and down, and the clamping cylinder 13a2 is used to clamp the full material tray.

[0043] Under normal conditions, the lifting cylinder 13a1 is in a retracted state and the clamping cylinder 13a2 is in a clamping state. When the full tray needs to be placed on the conveyor belt 8b, the second lifting platform 10 is lifted and ensures that the plane where the top of the second lifting platform 10 is located exceeds the upper end surface of the conveyor belt 8b; then the clamping cylinder 13a2 is released, and the stacked full trays fall to the top of the second lifting platform 10; then the lifting cylinder 13a1 drives the clamping cylinder 13a2 to lift to the position of the second layer of full trays and clamp to ensure that only one full tray is placed on the top of the second lifting platform 10; finally, the second lifting platform 10 descends so that the full tray is placed on the conveyor belt 8b.

[0044] like Figure 6 As shown, in this embodiment, second limit blocks 8h are provided at the ends of the two mounting vertical plates 8a, and the second limit blocks 8h can effectively prevent the material tray from moving excessively and causing the material tray to fall from the conveying crawler 8b.

[0045] In this embodiment, the first lifting platform 9, the second lifting platform 10 and the third lifting platform 11 are all cylinders, which not only ensures a stable lifting stroke but also saves production and processing costs.

[0046] According to the above structure, the working process of the automatic tooling device for the high-voltage wire harness tail cover is as follows:

[0047] Before the tail cover part b is tooled, the third lifting platform 11 descends, so that the empty tray on the third lifting platform 11 falls to the conveyor belt 8b, and is moved by the conveyor belt 8b to the empty tray storage assembly 12; then the first lifting platform 9 is lifted up, so that the empty tray is supported on the top of the support block 12b; then the second lifting platform 10 is lifted up, and the clamping assembly 13a ensures that only one full tray is placed on the second lifting platform 10; finally, the second lifting platform 10 descends, so that the full tray falls to the conveyor belt 8b, and is moved by the conveyor belt 8b to the third lifting platform 11, and the third lifting platform 11 is lifted up so that the empty tray rests on the bottom surface of the support plate 14, thereby completing the replacement of the entire full tray.

[0048] When starting to tool the tail cover part b, the clamping claw 4 clamps the high-voltage wire harness a and slides to the automatic tooling position through the slider 3b. The mechanical clamp 1 clamps the tail cover part b in the tray lifted by the third lifting platform 11, moves it to the position of the detection element 2 for detection, and then places it in 7a1. The tail cover part b is fixed by the action of the cylinder, and then the driving assembly 6 drives the entire clamping part 7 to slide toward the position of the clamping claw 4, thereby completing the tooling of the tail cover part b.

[0049] Such a design makes the tooling of the entire tail cover part b highly mechanized and the tooling speed of the tail cover part b fast. At the same time, the mechanized tooling also ensures the consistency of the product.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
