[0035] The detection base 9 includes base plate 91 and multiple wiring clamps 92;

[0036] The base plate 91 is arranged in the corresponding detection station 11;The clamping mechanism 6 is movably arranged in the side of the corresponding base plate 91;

[0037] The bottom of multiple wiring clamps 92 is respectively inserted into the top surface of the base plate 91, the clamping port of the wiring clamp 92 is arranged upwards, and the bottom of the wiring clamp 92 is electrically connected with the corresponding detection instrument 5;Multiple wiring clamps 92 are used to clamp multiple lead ends on the bottom of the transformer to be detected 4 one by one;

[0038] The clamping mechanism 6 is used to clamp the transformer to be detected 4 from the conveying line 2, and is used to place the transformer to be detected 4 above the corresponding base plate 91, and is used to apply pressure to the transformer to be detected 4 downwards, so that the clamping port of each wiring clamp 92 is inserted and conducted by the corresponding lead end.

[0039] Figure 1 It is the structural schematic diagram of one embodiment of the electrical performance detection device for transformer of the utility model, and the conveying line 2 running along X direction is arranged above the rack 1 in the drawing, multiple product carriers 3 are placed on the conveying line 2, the fixed frame 8 is placed on the product carrier 3, the transformer 4 being clamped is placed in the fixed frame 8, and the rack 1 is provided with multiple detection stations 11 for detecting different items of transformer.

[0040] Figure 2 It is the installation structural schematic diagram of clamping mechanism 6 and detection base 9, Figure 3 It is the structural schematic diagram of wiring clamp 92.

[0041] As Figure 1In the illustrated embodiment, when the product carrier plate 3 carrying the transformer 4 to be tested is delivered to any testing station 11 via the conveyor line 2 above the frame 1, the clamping mechanism 6 clamps the fixing frame 8 from the product carrier plate 3 at the testing station 11. The fixing frame 8 contains the clamped transformer 4 to be tested. The clamping mechanism 6 moves along the Y direction to above the corresponding base plate 91 and applies downward pressure when placing the fixing frame 8 above the base plate 91, so that the multiple lead ends located at the bottom of the transformer 4 to be tested are respectively inserted into the clamping openings of the corresponding terminal clamps 92. Then, the corresponding tester 5 transmits an electrical signal to the transformer 4 to be tested through the terminal clamps 92, thereby detecting the corresponding electrical performance items of the transformer 4 to be tested.

[0042] The detector in the prior art uses a spring probe as a tool for electrically connecting to the lead end. Since the contact area between the spring probe and the lead end is small, the spring probe may be displaced due to the vibration of the transmission equipment of the production line, resulting in invalid contact between the spring probe and the lead end, and thus inaccurate detection results. Therefore, compared with the prior art, the electrical performance detection device for the transformer using the wiring clamp 92 of the present invention has the advantages of high electrical connection stability and high detection result accuracy.

[0043] If all the electrical performance tests of the transformer 4 to be tested on the corresponding base plate 91 are qualified, the clamping mechanism 6 will clamp the transformer 4 to be tested and put it back into the conveyor line 2, so that the conveyor line 2 will convey the transformer 4 to be tested to the next testing station 11 to complete other electrical performance tests.

[0044] The conventional electrical performance test items of transformer 4 include power, resistance, withstand voltage and comprehensive performance.

[0047] The top surface of the defective product collecting rack 7 is used for placing transformers 4 that fail the inspection.

[0048] like Figure 1 As shown, if any item of the electrical performance test completed on the corresponding base plate 91 of the transformer to be tested 4 fails, the clamping mechanism 6 clamps the transformer to be tested 4 and places it on one end of the corresponding defective product collection rack 7, and then outputs it to the outside through the defective product collection rack 7 so that the maintenance station can pick it up for inspection and determine the cause of the defect.

[0049] Furthermore, the clamping mechanism 6 includes a gantry 60, a linear module 61, a suspension plate 62 and two clamping claws 63;

[0050] The gantry 60 extends along the Y direction; one end of the gantry 60 crosses an inspection station 11 and is disposed near the edge of the frame 1; the other end of the gantry 60 passes over the corresponding inspection base 9 and is disposed near one end of the corresponding defective product collection rack 7;

[0051] The linear module 61 includes a linear slide 611 and a moving cylinder 612;

[0052] The linear slide 611 is mounted on the top of the gantry 60. A guide rail pair 6111 is provided on the side of the linear slide 611 facing the corresponding detection base 9. The guide rail pair 6111 extends along the Y direction. The movable cylinder 612 is arranged upright, and the side of the movable cylinder 612 is slidably mounted on the guide rail pair 6111. The output end of the movable cylinder 612 extends downward.

[0053] The plate surface of the suspension plate 62 is set horizontally, and the suspension plate 62 extends along the Y direction. The top surface of the suspension plate 62 is connected to the output end of the moving cylinder 612; the two clamps 63 are respectively installed at the Y-direction ends of the bottom surface of the suspension plate 62.

[0054] like Figure 2 As shown, the moving cylinder 612 can drive the hanging plate 62 and the two clamps 63 to move along the Y direction between the conveyor line 2, the inspection base 9 and the defective product collection rack 7 located at the same inspection station 11, and can drive the hanging plate 62 to rise and fall at any position so that the two clamps 63 can clamp or remove the transformer 4. When the transformer 4 to be inspected is placed on the inspection base 9, the clamps 63 can apply downward pressure to the transformer 4 to be inspected by descending.

[0055] Furthermore, the wiring clamp 92 includes a base 921 , two clips 922 , two springs 924 and a plurality of hook bolts 923 ;

[0056] Both sides of the top of the base 921 are provided with hinge shafts 9211; the bottom of the base 921 is respectively inserted into the top surface of the base plate 91;

[0060] like Figure 3 As shown, when the transformer 4 to be tested is pressed downward, any lead end is located between the corresponding two inclined surfaces 9222. When the movable cylinder 612 descends and applies pressure through the two clamping jaws 63, the lead end is squeezed between the two clips 922 under the action of the downward force, so that the lead end is clamped between the corresponding two clips 922 and conducts.

[0061] The cooperation between the spring 924 and the hook bolt 923 enables the two clips 922 to open and close elastically, which can be applied to lead ends of different wire diameters and improve the stability of the lead ends clamped by the wiring clip 92.

[0062] Furthermore, the top of the clip 922 is provided with a plurality of tooth grooves 9221;

[0063] The tooth grooves 9221 extend in the horizontal direction, and multiple tooth grooves 9221 are arranged adjacent to each other up and down. Multiple tooth grooves 9221 are located on the inner side of one clip 922 facing the other clip 922, and the tooth groove 9221 located at the top is close to the bottom edge of the corresponding inclined surface 9222.

[0064] like Figure 3 As shown, a plurality of tooth grooves 9221 are provided on the top of the clip 922, which can increase the clamping force of the two clips 922 on the lead end and improve the stability of the electrical connection between the clip 922 and the lead end, thereby improving the accuracy of the detection result.

[0065] In summary, if Figures 1-3 In the embodiment of the utility model shown, the electrical performance testing device for the transformer, through the clamping mechanism 6 and the one-to-one correspondence between the terminal clamp 92 and the lead end, can complete the online testing of the transformer following the automatic production line for assembling the transformer, thereby avoiding a decrease in production efficiency, an increase in the online inventory of the products to be tested, and an increase in manufacturing costs.
