[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: Please refer to Figure 1 - Figure 6 , a combined electrical appliance automatic assembly device shown in the figure, including two mounting plates 1. A vision device 2 and an optical sensor 3 are mounted on one of the mounting plates 1, an optical dot matrix group 4 and an optical receiver 5 are mounted on the other mounting plate 1, and a docking plate 6 and an adjusting plate 7 fixed to one of the mounting plates 1. An adjusting rod 8 is inserted into the adjusting plate 7 in a threaded manner, a steering rod 9 is slidably inserted into the docking plate 6, a rotating frame 10 is arranged outside the mounting plate 1, the adjusting rod 8 and the steering rod 9 are docked with the rotating frame 10, a transverse adjusting part 11 docked with the adjusting rod 8 and the steering rod 9 is mounted on the rotating frame 10, and a telescopic rod 12 fixed to the bottom of the rotating frame 10. A longitudinal adjusting part 13 for driving the rotating frame 10 to rotate is arranged at the bottom of the rotating frame 10;

[0030] In this solution, the designed transverse adjusting part 11 performs corresponding telescoping and rotation on the adjusting rod 8 and the steering rod 9, so as to realize the steering and movement adjustment of the mounting plate 1. At the same time, by using the longitudinal adjusting part 13, the rotating frame 10 can be correspondingly rotated and lifted to realize the longitudinal movement and steering adjustment, so that when the relative position deviation between the male and female connectors is large, it can be quickly positioned and adjusted to reduce the relative position deviation.

[0031] Further, refer to Figure 1 、 Figure 3 - Figure 5 , the transverse adjusting part 11 includes two adjusting sleeves 14 rotatably mounted at both ends of the rotating frame 10. The two adjusting sleeves 14 are respectively slidably sleeved on the steering rod 9 and the adjusting rod 8. A large gear 15 is fixed to the outer end of the adjusting sleeve 14 sleeved on the steering rod 9. A steering motor 16 is fixed to the rotating frame 10 through a motor bracket. A small gear 17 is fixed to the output end of the steering motor 16. The large gear 15 and the small gear 17 are meshed with each other. An adjusting member 18 is mounted on the outer side of the adjusting sleeve 14 inserted into the adjusting rod 8;

[0032] Among them, the adjusting member 18 includes a fixing plate 19 fixed to the outer end of the adjusting sleeve 14. An adjusting motor 20 is fixed to the fixing plate 19. A small gear 21 is fixed to the output end of the adjusting motor 20. A large gear 22 meshed with the small gear 21 is fixed to the outer end of the adjusting rod 8;

[0033] In this solution, the steering motor 16 drives the first pinion 17 to rotate, so that the first large gear 15 rotates slowly. Then, it drives the corresponding rotation of the steering rod 9 and the docking plate 6, and further drives the corresponding rotation of the mounting plate 1. After that, when performing the movement adjustment, the adjustment motor 20 drives the second pinion 21 to rotate, so that the second large gear 22 and the adjustment rod 8 rotate correspondingly. As a result, the adjustment plate 7 threadedly connected to the adjustment rod 8 moves along the axial direction of the adjustment rod 8, realizing the movement adjustment of the mounting plate 1;

[0034] It should be noted that the gears of the second large gear 22 and the second pinion 21 have a certain width. During fine adjustment, the moving distance of the mounting plate 1 is less than the width of the two gears.

[0035] It should also be noted that the steering rod 9 is a rhombic rod, which can stably drive the docking plate 6 to rotate when rotating.

[0036] Specifically, refer to Figure 1 、 Figure 3 - Figure 5 The longitudinal adjustment part 13 includes a threaded barrel 23 fixed to the bottom of the rotating frame 10. A lead screw 24 is slidably inserted into the threaded barrel 23. The bottom of the lead screw 24 and the telescopic rod 12 are provided with a connecting plate 25 and are rotatably connected to the connecting plate 25. There are two telescopic rods 12, symmetrically distributed outside the lead screw 24. A driving component 26 for driving the lead screw 24 to rotate and revolve is installed on the connecting plate 25;

[0037] Among them, refer to Figure 3 - Figure 6 The driving component 26 includes a toothed ring 27 and two driving motors 28 fixed to the connecting plate 25 through a motor bracket. The bottom of the two telescopic rods 12 is fixed with a rotating gear 29, and the bottom of the lead screw 24 is fixed with a rotating gear 30. The output ends of the two driving motors 28 are fixed with driving gears 31. One of the driving gears 31 meshes with the rotating gear 29, and the other driving gear 31 meshes with the rotating gear 30;

[0038] In this solution, the principle of longitudinally adjusting the mounting plate 1: First, when longitudinal lifting is required, one of the driving motors 28 rotates, so that the bottom driving gear 31 rotates. The driving gear 31 drives the rotating gear 30 to rotate, so that the lead screw 24 rotates. The rotation of the lead screw 24 will drive the threaded barrel 23 to lift, so as to drive the rotating frame 10 to lift, thus realizing the lifting adjustment;

[0039] When performing longitudinal steering, the other driving motor 28 rotates to drive the driving gear 31 to mesh with the rotating gear 29, and the rotating gear 29 meshes with the toothed ring 27, so as to drive the connecting plate 25 to rotate along the toothed ring 27, realizing longitudinal steering.

[0040] It should be noted that the radius of the rotating gear 29 is greater than the radius of the driving gear 31, so that when the driving gear 31 rotates, the rotation of the rotating gear 29 can be slowly adjusted, making the lifting adjustment accuracy higher. Similarly, the diameter of the rotating gear 29 is much smaller than the inner diameter of the tooth ring 27, which also makes the steering adjustment accuracy higher.

[0041] In this solution, an assembly method of a combined electrical apparatus automatic assembly device includes the following steps;

[0042] S1, Install the male and female heads of the lotus head;

[0043] S2, Collect the visual images of the male and female heads through the vision device 2, and compare with the optical auxiliary dot matrix board to analyze and obtain the relative position deviation of the male and female heads in real time;

[0044] S3, Adjust the deviation through the lateral adjustment part 11 and the longitudinal adjustment part 13 until the accuracy reaches 0.01 mm to meet the assembly process requirements;

[0045] S4, Perform auxiliary manual assembly.

[0046] Embodiment 2: Please refer to Figure 5 and Figure 6 , This embodiment further describes Embodiment 1. The difference is that the structure of the connecting plate 25 is improved, making the butt joint with the tooth ring 27 smoother and the adjustment more stable.

[0047] Specifically, the connecting plate 25 is slidably butted with the top of the tooth ring 27. Side plates 32 that fit the outer side of the tooth ring 27 are fixed at both ends of the connecting plate 25, and balls 33 that fit the outer wall of the tooth ring 27 are installed inside the side plates 32.

[0048] In this solution, the side plates 32 are used to make the butt joint between the connecting plate 25 and the tooth ring 27 stable. At the same time, the balls 33 are used to reduce the friction force, making the steering smoother.

[0049] Embodiment 3: Please refer to Figure 3 - Figure 6 , This embodiment further describes other embodiments. The difference is that new structures are added to the mounting plate 1 and the arc plate 34, making the adjustment smoother and more stable, and the stability is better after the adjustment.

[0050] Specifically, referring to the figure, an arc plate 34 is fixed at the bottom of the mounting plate 1, an arc seat 35 adapted to the arc plate 34 is fixed at the bottom of the rotating frame 10, docking blocks 36 are fixed at both ends of the rotating frame 10, and arc rods 37 are slidably inserted into the docking blocks 36;

[0051] Meanwhile, referring to the figure, a dual-axis motor 38 is fixed inside the rotating frame 10. Both ends of the dual-axis motor 38 are fixed with threaded rods 39 through couplings. One end of the threaded rod 39 is threadedly sleeved with a trapezoidal block 40 adapted to the arc-shaped seat 35, and the other end is threadedly inserted with a pressing plate 41 that is slidably inserted into the side wall of the rotating frame 10. A pressing opening 42 is formed on the docking block 36. The pressing plate 41 extends into the pressing opening 42 and abuts against the arc-shaped rod 37. The threading directions of the two threaded rods 39 are opposite, so that when the dual-axis motor 38 is driven, the pressing plate 41 and the trapezoidal block 40 move synchronously in opposite directions.

[0052] In this solution, by using the designed arc-shaped rod 37, arc-shaped seat 35 and arc-shaped plate 34, the mounting plate 1 and the rotating frame 10 are more stable and smooth during the corresponding horizontal and vertical adjustments. At the same time, with the rotation of the dual-axis motor 38, the trapezoidal block 40 is driven to move. The trapezoidal block 40 will abut against the arc-shaped plate 34, thus playing a limiting role, enabling horizontal positioning and locking after the adjustment is completed. At the same time, by using the pressing plate 41 to abut against the arc-shaped rod 37, vertical locking can also be achieved.

[0053] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0054] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
