DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] like Figure 1-Figure 7As shown, a common mode inductor decoupling mechanism comprises a distribution station 1 and a common mode inductor body 2, two symmetrically installed wire clamping and air shearing mechanisms 3 are fixedly installed on the left and right sides of the upper surface of the distribution station 1, and a fixing mechanism 4 is fixedly installed in the middle of the upper surface of the distribution station 1, and the middle position of the fixing mechanism 4 is movably installed with the common mode inductor body 2;

[0032] First, the common-mode inductor body 2 is placed on the fixing mechanism 4, and the upper and lower ends of the common-mode inductor body 2 are fixed under the action of the fixing mechanism 4. Then, the wire end pins on the common-mode inductor body 2 can be clamped, pulled and sheared under the action of the mobile clamping and cutting of the wire clamping and air shearing mechanism 3, so that the length and number of turns of the wire end pins on the common-mode inductor body 2 can be limited. Then, under the action of the fixing mechanism 4, the fixed common-mode inductor body 2 can be loosened, and the common-mode inductor body 2 can be removed from the fixing mechanism 4.

[0033] The wire clamping gas shear mechanism 3 includes a first mounting frame 31, the bottom of the first mounting frame 31 is fixedly mounted on the left and right sides of the upper surface of the distribution station 1, a motor 32 is fixedly mounted on the side of the first mounting frame 31 away from the common mode inductor body 2, a screw rod 33 is fixedly mounted on the output end of the motor 32 through a coupling, a mounting slide 35 is threadedly connected to the outer surface of the screw rod 33, a mounting plate 36 is fixedly mounted on the top of the mounting slide 35, and a wire clamping gas shear 37 is fixedly mounted on the top of the mounting plate 36;

[0034] The motor 32 drives the screw rod 33 to rotate, so that the threaded mounting slide 35 can be moved, thereby controlling the position of the wire clamping gas shear 37 installed on the mounting plate 36;

[0035] The wire clamping gas shear 37 is a pneumatic clamping wire shear; the working principle of the pneumatic clamping shear is: the cylinder piston moves upward, driving the scissors to clamp and cut the work material. After the work material is clamped or cut, it is disengaged from the stroke valve. The stroke valve core is reset under the spring and the outlet is blocked. The reversing valve core moves upward, and the cylinder piston moves downward, returning to the state before cutting.

[0036] The fixing mechanism 4 includes a second mounting frame 41, the bottom of the second mounting frame 41 is fixedly installed on the middle of the upper surface of the distribution station 1, a first cylinder 42 is fixedly installed on the back of the second mounting frame 41, the output end of the first cylinder 42 passes through the rear of the second mounting frame 41 and is fixedly installed with a positioning seat 43, the upper surface of the positioning seat 43 is movably installed with the bottom of the common-mode inductor body 2, two sliders 45 are fixedly installed on the left and right sides of the bottom of the positioning seat 43, the bottoms of the two sliders 45 are slidably connected with slide rails 44, the bottoms of the two slide rails 44 are fixedly installed on the left and right sides of the upper surface of the bottom of the second mounting frame 41, a second cylinder 49 is fixedly installed on the top of the second mounting frame 41, the output end of the second cylinder 49 passes through the top of the second mounting frame 41 and is fixedly installed with a sleeve 410, and the bottom of the inner cavity of the sleeve 410 is movably installed in cooperation with the top of the common-mode inductor body 2.

[0037] The common-mode inductor body 2 is placed in the inner cavity of the positioning seat 43, and the sleeve 410 can be pushed downward under the action of the second cylinder 49, so that the bottom of the inner wall of the sleeve 410 is plugged into the top of the common-mode inductor body 2, and the common-mode inductor body 2 can be fixed;

[0038] By utilizing the sliding connection between the slide rail 44 and the slider 45 , the positioning seat 43 can be moved forward and backward under the action of the first cylinder 42 , so as to push the common mode inductor body 2 out from directly below the sleeve 410 , thereby facilitating material unloading.

[0039] like Figure 2 and Figure 3 As shown, a limiting slide rail 34 is fixedly mounted on the upper surface of the first mounting bracket 31 close to the common mode inductor body 2 , and the outer wall of the limiting slide rail 34 is slidably connected to the bottom of the mounting slide bracket 35 .

[0040] The sliding connection between the limiting slide rail 34 and the mounting slide 35 is used to guide the movement of the wire clamping gas shear 37 so that the wire clamping gas shear 37 can be easily moved left and right.

[0041] like Figure 2 and Figure 3 As shown, the limiting slide rail 34 is in a T-shape.

[0042] The limiting slide rail 34 is T-shaped, which is convenient for guiding the movement of the installation slide 35 and has a movement limiting function to avoid separation between the screw rod 33 and the installation slide 35.

[0043] like Figure 6 As shown, springs 411 are fixedly connected to the left and right sides of the top of the inner cavity of the sleeve 410 , and push blocks 412 are fixedly installed at the bottom of the two springs 411 , and the outer wall of the push block 412 is slidably connected to the inner wall of the sleeve 410 .

[0044] The spring 411 can be used to push the push block 412 downward, so that when the sleeve 410 moves upward, the spring 411 pushes the push block 412 to push the common-mode inductor body 2 out of the inner cavity of the sleeve 410, so that the sleeve 410 and the common-mode inductor body 2 are separated.

[0045] like Figure 7 As shown, tension springs 48 are fixedly installed at relative positions on the upper surfaces of the two sliders 45 , and an inclined push block 47 is fixedly installed on the top of the tension spring 48 . The outer wall of the inclined push block 47 is slidably connected to the inner wall of the positioning seat 43 .

[0046] The inclined push block 47 is pulled downward by the action of the tension spring 48 so as to exert a downward pulling force on the inclined push block 47 .

[0047] like Figure 4 and Figure 5 As shown, an inclined block 46 is fixedly installed in the middle of the front side of the upper surface of the bottom of the second mounting frame 41, and the inclined surface of the inclined block 46 is slidably connected with the inclined surface of the bottom of the inclined push block 47.

[0048] When the positioning seat 43 moves to the position of the inclined block 46, the inclined push block 47 can be pushed upward under the action of the sliding connection between the inclined block 46 and the inclined push block 47, so that the common-mode inductor body 2 in the inner cavity of the positioning seat 43 can be pushed out from the inner cavity of the positioning seat 43, so as to remove the common-mode inductor body 2.

[0049] The working principle of the utility model is as follows: first, the common-mode inductor body 2 is placed on the positioning seat 43, and then, under the action of the first cylinder 42, the positioning seat 43 is pulled successively to move the common-mode inductor body 2 to the bottom of the sleeve seat 410, and then, under the action of the second cylinder 49, the sleeve seat 410 is pushed downward to make the bottom of the inner wall of the sleeve seat 410 plug into the top of the common-mode inductor body 2, so that the common-mode inductor body 2 can be fixed, and then, through the action of the motor 32, the lead screw 33 is driven to rotate, so that the threaded mounting slide 35 can be moved, so as to control the position of the wire clamping gas shear 37 installed on the mounting plate 36, so as to clamp, pull and shear the wire end pins on the common-mode inductor body 2, so as to fix the wire end pins on the common-mode inductor body 2. The length and number of turns on the foot are limited, and then the sleeve 410 is driven to move upward under the action of the second cylinder 49, and the push block 412 can be pushed under the action of the spring 411 to push the common-mode inductor body 2 out of the inner cavity of the sleeve 410, so that the sleeve 410 and the common-mode inductor body 2 are separated, and then the positioning seat 43 is pushed under the action of the first cylinder 42, and the positioning seat 43 is moved forward under the guidance of the slide rail 44 on the slider 45. When the positioning seat 43 moves to the position of the inclined block 46, the inclined push block 47 can be pushed upward under the action of the sliding connection between the inclined block 46 and the inclined push block 47, so that the common-mode inductor body 2 in the inner cavity of the positioning seat 43 is pushed out from the inner cavity of the positioning seat 43, so that the common-mode inductor body 2 can be removed.

[0050] The wire clamping air shear 37 can also be replaced by a large-bore finger cylinder;

[0051] The motor 32 , the lead screw 33 , the limiting slide rail 34 and the mounting slide 35 may be replaced by a single-axis robot.

[0052] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
