Description
Technical Field

[0002] After the initial assembly of the common mode coil is completed, it is necessary to test it and cut off the unnecessary length of the lead wires before subsequent packaging and leaving the factory. Currently, through manual operation, one person determines the quantity of the coils to be tested according to the size of the product, uses copper wires to string twenty or thirty coils into a string for positioning, and then hands it over to the next process. Another tester presses the two sets of lead wires onto the test blades respectively, so that the blade cuts through the insulation layer of the lead wire and contacts the copper wire inside, and uses a test instrument to test whether it works properly. The qualified products are handed over to the lead trimming operator. After straightening the lead wires, one or two lead wires are trimmed. Each product needs to be trimmed two to four times.
[0003] This production method by manual operation has high manual labor intensity, high labor cost, and it is difficult to ensure the stability of the manual operation level. For example, insufficient pressure when connecting the lead wire to the tester is likely to cause poor contact, the test results are likely to deviate, and manual lead trimming is likely to cause inconsistent lead wire lengths, resulting in adverse effects on the electrical performance of the end customer's use and low production efficiency.

[0033] The test component 2 can be implemented by the prior art. One end of the conduction wire 110 is electrically connected to the conduction clip through the connection hole 130, and when the two sets of first conduction test pieces 210 are in alignment, they clamp and electrically connect the other end of the conduction wire 110.
[0034] In some embodiments, the second conduction test piece 220 is in a blade structure, which can be a large-sized 60° craft knife, and 6 to 7 pieces can be taken each time on each blade; corresponding to the setting of the common-mode coil lead wire, when the two sets of second conduction test pieces 220 are in alignment, they not only cut through the insulation layer of the coil lead wire of the mold, but also make electrical connection with the coil lead wire of the mold. The first conduction test piece 210 and the second conduction test piece 220 installed at the power output of the same first driving device 230 are arranged in a staggered manner. By sharing the same first driving device 230 for each group of the first conduction test piece 210 and the second conduction test piece 220, the cost is saved more, and the space occupied by the device is less.
[0035] The lead trimming component 3, the lead trimming component 3 is arranged between the starting position of the material holding platform 1 and the test component 2; the lead trimming component 3 includes two sets of symmetrically arranged second driving devices 310 and lead trimming cutters 320; a backing plate 330 is arranged between the two sets of symmetrically arranged second driving devices 310 and lead trimming cutters 320; the lead trimming cutter 320 is arranged at the power output end of the second driving device 310; the two sets of second driving devices 310 are used to drive the two sets of lead trimming cutters 320 to be in alignment or move away from the end face of the backing plate 330;
[0036] The conveying mechanism 4, the power output end of the conveying mechanism 4 is connected to the material holding platform 1 and the backing plate 330, and is used to drive the material holding platform 1 to move between the starting position of the material holding platform, the test station of the test component, and the lead trimming station of the lead trimming component.
[0037] In some embodiments, the starting position of the material holding platform and the lead trimming station of the lead trimming component are the same position. In this way, the conveying mechanism 4 can drive the material holding platform 1 to move to the starting position of the material holding platform or the corresponding test station of the test component 1, and the efficiency is higher with one forward and backward stroke.
[0038] Please refer to Figure 2 - Figure 4The pad 330 includes a pad frame 331 and a sliding block 332. The pad frame 331 is provided with a sliding groove 3311 for accommodating and limiting the sliding block 332; the sliding block 332 is slidably connected to the pad frame 331 through the sliding groove 3311, and an elastic member 333 is provided between the pad frame 331 and the sliding block 332 to keep the sliding block 332 extending out of the sliding groove 3311; the end of the sliding block 332 elastically abuts against the material holding platform 1; the two foot lines of the common mode coil foot line are respectively located on the two end surface sides of the sliding block 332.
[0039] The backing plate 330 further includes a cover plate 340 , which is connected to the backing plate frame 331 , so that the sliding block 332 is accommodated and limited in the sliding groove 3311 .
[0040] Please refer to Figure 4 and Figure 6 , including two groups of wire pulling protrusions 5, the two wire pulling protrusions 5 are respectively connected to the two power output ends of the second driving device 310, and are staggered with the shearing foot tool 320; the sliding block 332 is provided with a positioning groove 3321 corresponding to the wire pulling protrusion 5; the end of the sliding block 332 is provided with a sliding inclined surface 3322 corresponding to the inclined surface of the shearing foot tool 320.
[0041] Through the concave-convex matching of the wire drawing protrusion 5 and the alignment groove 3321, effective friction force can be provided to fully clamp the foot line of the mold coil. When the two foot cutting tools 320 are aligned, their inclined surfaces push the sliding inclined surface 3322, so that the sliding block 332 moves away from the material holding platform 1. At the same time, the wire drawing protrusion 5 and the alignment groove 3321 that have been matched with each other clamp the foot line straight. The two foot cutting tools 320 are further aligned, and the foot line can be cut accurately and with high quality. Then the foot line margin length size of the standard common mode coil foot meets the requirements. More standardization and unification can avoid the unstable quality of manual cutting, large errors, and easy bending and unstraightening of the foot line during operation.
[0042] Please refer to Figure 3 The material holding platform 1 is provided with a plurality of connection holes 130 , and the arrangement direction of the plurality of connection holes 130 is parallel to the moving direction of the material holding platform 1 ; the conductive wire 110 is connected to the material holding platform 1 through the connection holes 130 .

[0045] Please refer to Figure 3 , including a running bottom plate 8, and the material holding platform 1 is slidably connected to the running bottom plate 8.
[0046] The running bottom plate 8 plays a role of sliding guidance and provides sliding guidance for the movement of the material holding platform 1. The two are of a sliding connection structure of a slide rail and a slide groove.
[0047] Please refer to Figure 2 , including a control switch 6 that cooperates with the first driving device 230. When the conveying mechanism 4 drives the material holding platform 1 to move to the test station of the test component, the conveying mechanism 4 abuts against the control switch 6, and the control switch 6 controls the two first driving devices 230 to drive the two groups of symmetrically arranged first conduction test pieces 210 and second conduction test pieces 220 to be aligned.
[0048] In some embodiments, the control switch 6 is a touch switch, and the conveying mechanism 4 is provided with a matching structure corresponding to the touch switch.
[0049] Please refer to Figure 2 , the first driving device 230, the second driving device 310, and the conveying mechanism 4 are all air cylinders.
[0050] Please refer to Figure 2 , when the two second driving devices 310 drive the two trimming cutters 320 to be aligned with the end face of the backing plate 330, the end face of the trimming cutter 320 is in contact with the end face of the material holding platform 1 where the outlet of the wire outlet groove 120 is located.
[0051] Preferably, it includes a time relay (not shown) that cooperates with the first driving device 230.
[0052] Both groups of the first conduction test pieces 210 and the second conduction test pieces 220 include corresponding test triggers 7.
[0053] When the first driving device 230 drives the two symmetrically arranged first conduction test pieces 210 and second conduction test pieces 220 to be engaged, during the engagement period, manually or by an automated device, operate the two test triggers 7 to test the two wire-pulling feet one by one. In order to save the program and reduce the step process, when the conveying mechanism 4 abuts against the control switch 6, the time relay starts timing when the two first driving devices 230 drive the two first conduction test pieces 210 and second conduction test pieces 220 to be engaged or before the engagement starts, leaving the operation control time for the test trigger 7, and then controlling the first driving device 230 to drive the two first conduction test pieces 210 and second conduction test pieces 220 to separate.
[0054] Working principle of the common mode coil testing and wire-cutting integrated machine of the present invention:
[0055] 1 Load the common mode coil to be tested onto the conduction wire 110. Specifically, the inner ring of the common mode coil passes through the conduction wire 110, and the two wire-pulling feet are placed neatly corresponding to the wire outlet grooves 120; press the operation switch of the conveying mechanism 4.
[0056] 2 The conveying mechanism 4 carries the material holding platform 1 and the backing plate 330 together, and moves the material holding platform 1 from the starting position of the material holding platform to the test station of the test component. After arriving, the conveying mechanism 4 automatically stops, and at the same time, the conveying mechanism 4 abuts against the control switch 6.
[0057] 3 When the conveying mechanism 4 touches the touch switch, the two first driving devices 230 on both sides simultaneously push the first conduction test piece 210 and the second conduction test piece 220 to connect the wire feet, and the blade structure of the second conduction test piece 220 cuts through the insulation layer of the wire feet for testing:
[0058] 4 Since the power output ends of the two first driving devices 230 are relatively far away from each other, control them according to the time relay to prevent the power output ends of the two first driving devices 230 from retracting before the test is completed.
[0059] 5 When the blade structure of the second conduction test piece 220 clamps the product wire feet, one side of the two wire-pulling feet has been tested. At the same time, it is necessary to observe the test value or sound of the tester. If it is qualified, it is necessary to operate the test trigger 7 on the other side in time to test the conduction switch and complete the test of the two winding parts on the other side:
[0060] 6 In some embodiments, through the test trigger 7, the test of the common mode coil only needs to press the test trigger 7 once to complete the test.
[0061] 7 The time of the test action needs to be less than the time when the power output ends of the two first driving devices 230 are relatively far away and retract, so as to prevent the product from not being tested on one side and causing defective products to flow out.
[0062] After the test is completed, the conveying mechanism 4 pushes the material holding platform 1 to the starting position. After stopping, the second driving device 310 of the lead trimming assembly 3 is controlled to trim the leads of the common mode coil.
[0063] 9 A wire pulling bump 5 is provided at the power output end of each of the two groups of second driving devices 310, corresponding to the alignment groove 3321 of the sliding block 332, which can straighten the lead wires before lead trimming.
[0064] 10 After the lead trimming is completed, the power output ends of the second driving devices 310 move relatively away from each other. At this time, the material holding platform 1 is at the starting position, and the tested and lead-trimmed common mode coil finished products can be directly taken out. If the material holding platform 1 is at the lead trimming station, then the conveying mechanism 4 can drive the material holding platform 1 to move back to the starting position of the material holding platform. Finally, the common mode coil to be tested and lead-trimmed is loaded onto the material holding platform 1, and the test and lead trimming are continuously performed in a reciprocating cycle.
[0065] In summary, for this integrated common mode coil testing and lead trimming machine, one operator can operate one machine to complete the testing and lead trimming operations of three processes on the integrated machine platform; in terms of labor costs, the operators for two processes can be saved; the wire threading process is eliminated, avoiding the need to pick up and move the product and pull the lead wires for each process; it can achieve a result of 320 - 400 pcs / hour, which is more than twice the working efficiency of the traditional three processes with three operators.
