[0047] The spring contact finger 10 is a widely used and important component. It is a helical coil made of copper wire or alloy and is a crucial part of the electrical connection between conductors. Its overall shape is elliptical, allowing for stretching or compression in various directions. The spring contact finger 10 and the connecting conductor 20 (also called the conductive contact) together form the electrical connection assembly, enabling the transmission of high current within a relatively small space. A schematic diagram of the connecting conductor used in GIS (Gas Insulated Switchgear) is shown below. Figure 1 and Figure 2 As shown, the overall shape is a rotating body with a central hole, and two rectangular cross-section grooves are set inside to assemble the spring contact finger 10.

[0048] Schematic diagram of GIS spring contact finger 10 as shown below Figure 3 and Figure 4 As shown, the overall shape is a ring-shaped spiral. During assembly, press the spring contact finger 10 into the rectangular groove of the connecting conductor 20 and ensure that the outer contour of the spring is in full contact with the groove surface to complete the assembly.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] The assembly device provided in this embodiment of the invention is used to assemble the spring contact finger 10 and the connecting conductor 20 of a gas-insulated fully enclosed combined electrical appliance, such as... Figure 1 and Figure 4 As shown, the spring contact finger 10 and the connecting conductor 20 are part of a gas-insulated fully enclosed combined electrical appliance, and the assembly device includes:

[0051] like Figure 5 and Figure 6As shown, there is a support unit 30 and a positioning unit 40. The support unit 30 has a support surface 31, and the positioning unit 40 is disposed on the support surface 31 for positioning and fixing the connecting conductor 20.

[0052] like Figure 7 As shown, the pressing module unit 50 includes: a first linear lifting mechanism 51 and a pressing member 52. The first end of the first linear lifting mechanism 51 is disposed on the support surface 31, and the second end of the first linear lifting mechanism 51 is connected to and drives the pressing member 52 to press the spring contact finger 10 down to the first preset position 21 in the connecting conductor 20.

[0053] like Figure 8 As shown, the side-pressure module unit 60 includes: a second linear lifting mechanism 61, a horizontal linear motion mechanism 62, and a side-pressure member 63; the second linear lifting mechanism 61 is disposed on the support surface 31, the first end of the horizontal linear motion mechanism 62 is connected to the second linear lifting mechanism 61 and driven by it to perform vertical movement, and the second end of the horizontal linear motion mechanism 62 is connected to and drives the side-pressure member 63 to press the spring contact finger 10 to the second preset position 22 in the connecting conductor 20.

[0054] In the above technical solution, when it is necessary to assemble the spring contact finger 10 and the connecting conductor 20, the positioning unit 40 is used to fix the connecting conductor 20 to the support surface 31, and the spring contact finger 10 is placed inside the connecting conductor 20. Because the spring contact finger 10 is elastic, it will cause the spring contact finger 10 to be stuck on the inner circumferential surface of the connecting conductor 20. The first linear lifting mechanism 51 is activated, causing the first linear lifting mechanism 51 to drive the pressing member 52 to move vertically downward. During the vertical downward movement of the pressing member 52, the end of the pressing member 52 away from the first linear lifting mechanism 51 contacts the circumferential surface of the spring contact finger 10. The pressing member 52 applies downward pressure to the spring contact finger 10, causing the spring contact finger 10 to move downward along the axial direction of the connecting conductor 20. When the spring contact finger 10 moves to the first preset position 21 inside the connecting conductor 20 (the spring contact finger 10 is stuck in the second preset position 22 inside the connecting conductor 20 under the action of its elastic restoring force). Then the pressing member 52 stops applying downward pressure to the spring contact finger 10, and the first linear lifting mechanism 51 drives the pressing member 52 to move vertically upward, so that the pressing member 52 is no longer inside the connecting conductor 20. If the spring contact finger 10 is not engaged in the second preset position 22, the second linear lifting mechanism 61 is activated. The second linear lifting mechanism 61 drives the horizontal linear motion mechanism 62 to move vertically downward, causing the side pressure member 63 on the horizontal linear motion mechanism 62 to move downward and enter the connecting conductor 20. When the side of the side pressure member 63 and the circumference of the spring contact finger 10 are on the same horizontal plane, the second linear lifting mechanism 61 stops moving, and the horizontal linear motion mechanism 62 starts. The horizontal linear motion mechanism 62 drives the side pressure member 63 to move radially within the connecting conductor 20. During the radial movement, the side of the side pressure member 63 contacts the circumference of the spring contact finger 10 and presses the spring contact finger 10 into the second preset position 22 to complete the assembly of the spring contact finger 10 and the connecting conductor 20. After the spring contact finger 10 and the connecting conductor 20 are assembled, a first component is formed. The first component is removed from the positioning unit 40, and the assembly and fixing of the next spring contact finger 10 and the connecting conductor 20 can be carried out. In this technical solution, the assembly efficiency is improved and manpower and material resources are saved through the coordinated work of the support unit 30, positioning unit 40, pressing module unit 50 and side pressing module unit 60.

[0055] In one of the alternative technical solutions, such as Figure 7 As shown, the first linear lifting mechanism 51 includes: a first rotary motor 511, a first bracket 512, a first lead screw 513, a horizontal connecting rod 514, and a first base 515; the bottom of the first base 515 has a first lead screw nut;

[0056] The first rotary motor 511 is fixed to the upper surface of the support surface 31 via the first bracket 512. This can be understood as the part of the first rotary motor 511 facing the support surface 31 being fixed to the first end of the first bracket 512, and the second end of the first bracket 512 being fixed to the support surface 31. The output shaft of the first rotary motor 511 is connected to the first lead screw 513 via a coupling. The first lead screw 513 and the first bracket 512 are arranged in the same direction, which is vertical. A first lead screw nut is fitted on the first lead screw 513 to drive the first base 515 to move along the axial direction of the first lead screw 513. The first end of the horizontal connecting rod 514 is connected to the first base 515, and the second end of the horizontal connecting rod 514 is connected to the pressing member 52, so that the horizontal connecting rod 514 with the pressing member 52 moves vertically up and down with the first base 515.

[0057] In the above technical solution, when the first rotary motor 511 is started, due to the setting of the first lead screw 513 and the first lead screw nut, the rotational motion of the first rotary motor 511 is converted into linear motion. Therefore, the first base 515 moves vertically along the first lead screw 513, thereby driving the pressing member 52 to move vertically. When the pressing member 52 moves vertically downward, it applies a downward pressure to the spring contact finger 10 so that the spring contact finger 10 is pressed down to the first preset position 21.

[0058] Optimize the above technical solutions, such as Figure 7 As shown, the pressing member 52 is a pressing plate, the second end of the horizontal connecting rod 514 is provided with a threaded rod, the first end of the pressing plate is provided with a threaded hole connected to the threaded rod, and the end face of the second end of the pressing plate is used to press the spring contact finger 10 down to the first preset position inside the connecting conductor 20.

[0059] In the above technical solution, the end face area of ​​the second end of the pressure plate is larger, which increases the contact area between the second end of the pressure plate and the spring contact finger 10, thereby improving the accuracy of pressure application. At the same time, the threaded rod and threaded hole allow for adjustment of the relative position of the pressure component 52 as needed.

[0060] Further optimization of the above technical solutions, such as Figure 7 As shown, at least one side of the pressure plate is an arc-shaped surface that fits the inner circumferential surface of the connecting conductor 20. In this design, the arc-shaped surface and the inner circumferential surface of the connecting conductor 20 fit together during the pressing process, making the pressing process smoother. Preferably, all four sides of the pressure plate are arc-shaped surfaces that fit the inner circumferential surface of the connecting conductor 20.

[0061] In an alternative embodiment, such as Figure 8As shown, the second linear lifting mechanism 61 includes: a second rotary motor 611, a second bracket 612, a second lead screw 613, a vertical connecting rod 614, and a second base 615; the second base 615 has a second lead screw nut;

[0062] The second rotary motor 611 is fixed to the lower surface of the support surface 31 by the second bracket 612. It can be understood that one end of the second bracket 612 is connected to the second rotary motor 611, and the other end is connected to the lower surface of the support surface 31. The output shaft of the second rotary motor 611 is connected to the second lead screw 613 through a coupling. The second lead screw 613 and the second bracket 612 are arranged in the same direction. A second lead screw nut is sleeved on the second lead screw 613. The first end of the vertical connecting rod 614 is connected to the second base 615. The support surface 31 has a through hole along its thickness. The second end of the vertical connecting rod 614 passes through the through hole and is connected to the horizontal linear motion mechanism 62. The diameter of the vertical connecting rod 614 is smaller than the diameter of the through hole so that the vertical connecting rod 614 can slide relative to the through hole.

[0063] In the above technical solution, when the second rotary motor 611 is started, due to the setting of the second lead screw 613 and the second lead screw nut, the rotational motion of the second rotary motor 611 is converted into linear motion. Therefore, the second base 615 moves vertically along the second lead screw 613, and then drives the horizontal linear motion mechanism 62 to move vertically through the vertical connecting rod 614. At the same time, the side pressure member 63 set on the horizontal linear motion mechanism 62 moves vertically along with the horizontal linear motion mechanism 62.

[0064] Optimize the above technical solutions, such as Figure 8 As shown, the horizontal linear motion mechanism 62 includes: a linear motor 621 and a motor base 622;

[0065] The second end of the vertical connecting rod 614 is connected to the bottom surface of the motor base 622, and a linear motor 621 is provided on the top surface of the motor base 622; the driving end of the linear motor 621 is connected to the side pressure member 63 to drive the side pressure member 63 to make horizontal linear motion. Specifically, the linear motor 621 is arranged horizontally.

[0066] In the above technical solution, when the spring contact finger 10 needs to be pressed to the second preset position 22, after the second linear lifting mechanism 61 drives the side pressing member 63 into the connecting conductor 20, the linear motor 621 starts to drive, so that the side pressing member 63 moves radially in the connecting conductor 20. During the movement, the side wall of the side pressing member 63 will lock the spring contact finger 10 into the second preset position 22 in the connecting conductor 20.

[0067] In one of the alternative technical solutions, such as Figure 8As shown, the drive end of the linear motor 621 is connected to the drive-side pressure component 63 via a sliding module;

[0068] The sliding module includes a slide rail 623, a slider 624 that slides with the slide rail 623, and a connecting plate 625 connected to the slider 624. The driving end of the linear motor 621 is connected to the top of the connecting plate 625, and a side pressure member 63 is connected to the bottom of the connecting plate 625.

[0069] In the above technical solution, the arrangement of slide rail 623 and slider 624 enables the side pressure member 63 to move more smoothly in horizontal linear motion.

[0070] In the above technical solution, the side pressure member 63 is a side pressure rod. The first end of the side pressure rod is connected to the connecting plate 625, and the side of the second end of the side pressure rod is used to press the spring contact finger 10 to the second preset position 22 inside the connecting conductor 20.

[0071] In the above technical solution, the side pressure rod improves the assembly efficiency of the spring contact finger 10 and the connecting conductor 20. Preferably, the side of the second end of the side pressure rod has a groove, which is an arc shape that matches the outer circumference of the spring contact finger 10, so as to more quickly insert the spring contact finger 10 into the second preset position 22. In one embodiment, the groove of the side pressure rod can hook the spring contact finger 10 from the bottom of the connecting conductor 20, so that it is pressed into the rectangular groove of the connecting conductor 20 on one side (i.e., the second preset position 22), thus avoiding the spring contact finger 10 being pressed too much by the pressing member 52, causing the spring contact finger 10 to be pressed to the bottom of the connecting conductor 20.

[0072] In one of the alternative technical solutions, such as Figure 9 and Figure 10 As shown, the positioning unit 40 includes: a compression cylinder 41, a connecting rod 42, and a ball positioner 43;

[0073] The compression cylinder 41 includes a first compression cylinder and a second compression cylinder; the connecting rod 42 includes a first connecting rod 421 and a second connecting rod 422; and the ball positioner 43 includes a first ball positioner 431 and a second ball positioner 432.

[0074] A first compression cylinder is connected to the first end of a first connecting rod 421, and a second compression cylinder is connected to the first end of a second connecting rod 422. A first spherical positioner 431 is provided at the second end of the first connecting rod 421, and a second spherical positioner 432 is provided at the second end of the second connecting rod 422. A fixed space for fixing the connecting conductor 20 is formed between the first spherical positioner 431 and the second spherical positioner 432. Specifically, the compression cylinder 41 is disposed on the upper surface of the support surface 31, and the spherical positioner 432 is slidable relative to the upper surface of the support surface 31. In use, when it is necessary to clamp the connecting conductor 20 within the fixed space, the first compression cylinder drives the first connecting rod 421 (e.g., ...). Figure 10 The connecting rod on the left side moves to the right, causing the first ball positioner 431 to move to the right, and the second compression cylinder drives the second connecting rod 422 (as shown in the image). Figure 10 The connecting rod on the right side moves to the left, causing the second spherical locator 432 to move to the left, so as to clamp and fix the connecting conductor 20.

[0075] Optimize the above technical solutions, such as Figure 10 As shown, the positioning unit 40 further includes a slider 44 and a slide rail 45; wherein, the slider 44 includes a first slider 441 and a second slider 442, and the slide rail 45 includes a first slide rail 451 and a second slide rail 452. Specifically, the first slide rail 451 and the second slide rail 452 are both disposed on the support surface 31, and the first slider 441 and the first slide rail 451 cooperate, and the second slider 442 and the second slide rail 452 cooperate; the opposite ends of the first slider 441 are respectively provided with a first spherical positioner 431 and a fourth spherical positioner 434, and the opposite ends of the second slider 442 are respectively provided with a second spherical positioner 432 and a third spherical positioner 433. In use, the first compression cylinder can drive the first spherical positioner 431 and simultaneously drive the fourth spherical positioner 434 to move synchronously through the first slider 441, and the second compression cylinder can drive the second spherical positioner 432 and simultaneously drive the third spherical positioner 433 to move synchronously through the second slider 442.

[0076] In a specific usage process, such as Figure 9 and Figure 10 As shown, the spherical positioner 43 contacts the outer contour of the connecting conductor 20, generating a centripetal force to clamp the connecting conductor 20. Specifically, the connecting rod 42 is rigidly connected to the output shaft of the compression cylinder 41, and the connecting rod 42 is arranged in a mirror image, forming an inverted T-shape. When the compression cylinder 41 is activated, the connecting rod 42 drives the spherical positioner 43 to compress towards the center. The slider 44 and the slide rail 45 are in sliding engagement, and the connecting rod 42 drives the slider 44 to move along the slide rail 45 through the spherical positioner 43.

[0077] In an alternative embodiment, such as Figure 5As shown, the support unit 30 includes a support table 32, the tabletop of which is a support surface 31. The support table 32 is positioned at a certain height during the assembly process of the assembly device, making assembly more convenient.

[0078] In an alternative embodiment, such as Figure 11 , Figure 12 and Figure 13 As shown, in order to improve the assembly speed of the assembly device, the assembly device also includes a mechanical gripper 70. The mechanical gripper is used to place the spring contact finger 10 into the connecting conductor 20. After the mechanical gripper 70 places the spring contact finger 10 into the connecting conductor 20, the pressing module unit 50 and the side pressing module unit 60 are driven in sequence to press down and side press the spring contact finger 10.

[0079] Optimize the above technical solutions, such as Figure 11 As shown, the mechanical gripper 70 includes: a side gripper 71, a centering gripper 72, a transmission device 73, and a cylinder 74. The cylinder 74, through the transmission device 73, enables the side gripper 71 and the centering gripper 72 to work together to grip the spring finger 10. The spring finger gripper is generally laid out in a flat pattern. The front clamping part of the spring finger gripper consists of the side gripper 71 and the centering gripper 72. The side gripper has a rectangular cross-section concave structure, arranged mirror-image of the gripper's center line. The front end of the centering gripper 72 is designed with two semi-circular cross-section grooves, which fully contact the outer contour of the circular cross-section of the spring finger 10, clamping the spring finger. The side gripper 71 makes frictional contact with the tangent of the outer circle of the spring finger. The transmission device 73 is assembled with the cylinder 74, and the built-in transmission linkage is connected to the side gripper 74 and the centering gripper 72. While the centering gripper 72 clamps the spring contact finger, the side gripper 72 presses inward towards the center line, compressing the spring contact finger into an ellipse. In a specific embodiment, the mechanical gripper 70 can be a conventional mechanical gripper, which will not be described in detail here.

[0080] The technical features mentioned above, those to be mentioned below, and those shown individually in the accompanying drawings can be combined arbitrarily, provided that the combined technical features are not contradictory. All feasible combinations of features are the technical content explicitly described herein. Any one of the multiple sub-features contained in the same statement can be applied independently, without necessarily being applied together with other sub-features.

[0081] Advantages of this technical solution:

[0082] The assembly process is highly efficient, with full automation across the entire assembly stage, significantly improving efficiency compared to existing manual operations. Furthermore, the lateral spring pressing process simplifies the assembly flow and enhances efficiency. High positioning accuracy is achieved through the use of spherical positioning devices, grooved side pressing components, probes, and an electronic control system, resulting in higher assembly precision compared to other automation solutions. This provides a more significant advantage over manual operations, effectively preventing workflow disruptions and parts rework caused by assembly errors. The fully automated assembly method effectively avoids quality issues such as reversed spring contacts, omissions, and incorrect installations common in manual operations.
