[0041] The guiding component 3 includes a guide rail 31, a support frame 32 and a guiding rod 33; the guide rail 31 extends along the X-axis direction, and a plurality of the guide rails 31 are arranged at intervals along the Y-axis direction on one side of the installation groove 10;

[0042] One end of the guiding rod 33 is fixed to the support frame 32, and the other end of the guiding rod 33 extends towards the fixing frame 2 along the X direction; the other end of the guiding rod 33 is used to extend into and pass through the corresponding winding turn 42, and is used to abut against the end face of the built-in magnetic core 43 to be installed.

[0043] Such as Figures 1-3 is a schematic structural diagram of the product carrier for the transformer of the present utility model. Figure 4 is a schematic structural diagram of the assembled transformer 4.

[0044] On the production line for assembling the transformer, first place the bobbin 41 with winding turns 42 placed inside in the placement groove 210, and then use the pushing device to push the plurality of guiding rods 33 to move towards the corresponding winding turns 42 along the guidance of the guide rail 31, and make the other end of the guiding rod 33 extend into and pass through the corresponding winding turn 42. At the same time, use the manipulator to grasp the built-in magnetic core 4, and move the built-in magnetic core 43 close to the side of the corresponding winding turn 42 away from the guiding rod 33 through the movement of the manipulator, so that one end face of the built-in magnetic core 43 abuts against the other end of the guiding rod 33. Then, drive the plurality of guiding rods 33 to retract along the guide rail 31 through the pushing device, so that the built-in magnetic core 43 follows the guiding rod 33 into the corresponding winding turn 42 until both ends of the built-in magnetic core 43 are exposed outside the corresponding winding turn 42, that is, the assembly of the winding turn 42 and the built-in magnetic core 43 is completed.

[0045] In addition, the bottom of the placement groove 210 penetrates through the plate surface of the bottom plate 21, so that the lead end of the winding turn 42 can be exposed downward outside the bottom of the bobbin 41, thereby improving the operation convenience of the electrical performance detection of the transformer 4.

[0046] Further, the support frame 32 includes a horizontal section 321 and a vertical section 322. The horizontal section 321 is slidably installed on the guide rail 31, and the vertical section 322 is erected upward; one end of the guiding rod 33 is fixed to the surface of the vertical section 322 facing the installation groove 1;

[0047] The shape of the cross-section of the guiding rod 33 perpendicular to the X-axis direction is the same as the shape of the cross-section of the inner wall surface of the corresponding winding turn 42 perpendicular to the X-axis direction, and the area of the cross-section of the guiding rod 33 perpendicular to the X-axis direction is smaller than the area of the cross-section of the inner wall surface of the corresponding winding turn 42 perpendicular to the X-axis direction.

[0048] Using the L-shaped support 32 to fix the guiding rod 33 can prevent the guiding rod 33 from tilting upward, thereby improving the stability of the guiding rod 33 during the movement process.

[0049] The outer shape of the outer peripheral surface of the guiding rod 33 arranged in this way is similar to the shape of the inner space formed by the inner wall surface of the corresponding winding turn 42, having a profiling effect. The outer peripheral surface of the guiding rod 33 can be in clearance fit with the inner wall surface of the winding turn 42, which can improve the smoothness of the guiding rod 33 extending into the corresponding winding turn 42 and avoid hard contact between the outer peripheral surface of the guiding rod 33 and the inner wall surface of the winding turn 42, further improving the assembly efficiency and assembly quality of the winding turn 42 and the built-in magnetic core 43.

[0050] Preferably, the outer surface of the guiding rod 33 is a smooth surface, and the periphery of the end surface at the other end of the guiding rod 33 is a chamfered round edge 331.

[0051] Setting the outer surface of the guiding rod 33 as a smooth surface can prevent the guiding rod 33 from scratching the insulating paint on the surface of the winding turn 42 during the movement process.

[0052] As Figure 3 shown, when more than two winding turns 42 need to be sleeved on the outer periphery of a built-in magnetic core 43 during assembly, even if there is a slight misalignment between two adjacent winding turns 42 placed in the same winding turn slot in the skeleton 41, using the guiding rod 33 with a chamfered round edge 331 at the periphery of the end surface can reduce the blockage of the misaligned part to the guiding rod 33, thereby reducing the failure probability of the guiding rod 33.

[0053] Furthermore, the groove wall of the placement groove 210 is provided with a plurality of inwardly protruding inner convex blocks 2101, and the inner convex blocks 2101 are used to support the bottom of the skeleton 41.

[0054] As Figure 2 shown, through the support of a plurality of inwardly protruding inner convex blocks 2101, the installation stability of the skeleton 41 in the placement groove 210 can be improved.

[0055] Furthermore, the fixing frame 2 further includes a plurality of clamping plate assemblies 22;

One side of the clamping plate 221 is fixed to one end of the screw rod 222, and the other side of the clamping plate 221 faces the placement groove 210. The wing nut 224 is sleeved on the other end of the screw rod 222.

[0060] As Figure 2 shown, when assembling the transformer 4, by rotating the wing nut 224, the two groups of screw rod fixing plates 223 are brought closer, and the two strip-shaped magnetic cores 44 are clamped from both sides, so that the end faces of both ends of the multiple built-in magnetic cores 43 are abutted against the side surfaces of the strip-shaped magnetic cores 44.

[0061] Furthermore, the clamping plate 221 includes an elastic soft pad 2212 and a mounting plate 2211;

[0062] One side of the mounting plate 2211 is fixed to one end of the screw rod 222, the elastic soft pad 2212 is pasted on the other side of the mounting plate 2211, and the elastic soft pad 2212 faces the placement groove 210.

[0063] As Figure 2 shown, using the elastic soft pad 2212 can prevent the clamping plate 221 from scratching the strip-shaped magnetic core 44.

[0068] Preferably, the multiple screw rods 222 located on the two groups of screw rod fixing plates 223 are arranged in a staggered manner.

[0069] When stacking the assembled transformer 4 together with the fixing frame 2, the multiple screw rods 222 are arranged in a mutually staggered manner, so that two adjacent fixing frames 2 can be placed close to each other, thereby improving the space utilization rate and turnover efficiency of stacking the fixing frames 2.

[0070] Preferably, any one of the screw rod fixing plates 223 in a group of the screw rod fixing plates 223 close to the guiding assembly 3 is located between the two guiding rods 33.

[0071] As Figure 1 shown, this can avoid the screw rod fixing plate 223 from blocking the operation of the guiding rod 33, and make the corresponding wing nut 224 located between the two guiding rods 33, and also improve the operation convenience of screwing the wing nut 224.

[0073] The plate surface of the screw rod fixing plate 223 extends along the Y-axis direction and is used to block the corresponding side surface of the skeleton 41.

[0074] As Figure 1 shown, when synchronously installing multiple built-in magnetic cores 43, the plate surface of the above-mentioned screw rod fixing plate 223 that blocks the corresponding side surface of the skeleton 41 can be closely attached to the end surface of the multiple built-in magnetic cores 43 far from the guiding rod 33, so that the above-mentioned screw rod fixing plate 223 can cooperate with the multiple guiding rods 33 and respectively clamp the two end surfaces of the multiple built-in magnetic cores 43. Then, by pushing the above-mentioned screw rod fixing plate 223 along the X direction and synchronously retracting the multiple guiding rods 33 along the X direction, the whole of the multiple built-in magnetic cores 43 can smoothly enter the corresponding winding turns 42, thereby further improving the installation efficiency of the built-in magnetic cores 43.
