[0046] On the one hand, the utility model provides a kind of inductance coil test (voltage withstand test or inductance test) mechanism, as shown in Figure 1, including fixed base plate 80, fixed base plate 80 is equipped with test seat fixed support 810, test seat fixed support 810 is equipped with the test seat 84 for placing the inductance coil 17 to be tested and being cross-shaped; Figures 2-6

[0047] The length direction two sides of test seat 84 are equipped with clamping device, and clamping device includes finger air cylinder 81 arranged on fixed base plate 80, and parallel clamping jaw of finger air cylinder 81 is equipped with positioning clamping piece fixed support 82 and positioning clamping piece 83 for clamping inductance coil base plate 171 to be tested located at the end of positioning clamping piece fixed support 82;

[0048] ​The width direction of the test seat 84 is provided with a test device, which comprises an open cylinder 811 arranged on the fixed bottom plate 80, a probe switching fixed support 89 arranged at the two end output ends of the open cylinder 811, and a probe fixing device arranged at the end of the probe switching fixed support 89, wherein the probe fixing device is provided with a retractable probe 85, and the probe 85 is connected to a voltage resistance / inductance tester (not shown) through a wire.

[0049] In use, first, the inductance coil 17 to be tested is placed on the cross-shaped test seat 84, the finger cylinder 81 is closed, the positioning clamping piece 83 clamps and positions the inductance coil base / plate 171 to be tested, then the open cylinder 811 is closed, the probe 85 contacts the PIN pin of the inductance coil 17 to be tested, the voltage resistance / inductance value of the inductance coil 17 to be tested is tested (at this time, the probe 85 is connected to the voltage resistance / inductance tester according to requirements), after the test is completed, the open cylinder 811 is opened, the probe 85 leaves the PIN pin of the inductance coil, finally, the finger cylinder 81 is opened, the positioning clamping piece 83 releases the inductance coil base / plate, and the inductance coil is taken away, and the above process can be repeated to complete the production.

[0050] The inductance coil testing mechanism has the test seat fixed support provided with the cross-shaped test seat for placing the inductance coil to be tested, the test seat is cross-shaped and can provide better support force for the base / plate of the inductance coil to be tested; the clamping device comprises the finger cylinder arranged on the fixed bottom plate, the parallel clamping jaws of the finger cylinder are provided with the positioning clamping piece fixed support and the positioning clamping piece arranged at the end of the positioning clamping piece fixed support and used for clamping the base / plate of the inductance coil to be tested, the clamping device directly clamps the base / plate of the inductance coil to be tested, has the simple structure and is convenient to use, can stably clamp and position the inductance coil to be tested, can quickly complete the voltage resistance / inductance test of the inductance coil to be tested, improves the test precision, and improves the production efficiency.

[0051] As shown in Figure 3 The positioning clamping piece fixed support 82 can be Z-shaped, the positioning clamping piece 83 can be driven to clamp and release without affecting other accessories, and the space utilization of the inductance coil testing mechanism is improved.

[0052] The positioning clamping piece 83 can be provided with a long strip fixed hole 831 extending along the length direction of the test seat 84, the long strip fixed hole 831 is provided with a fixed screw 832 for fixing the positioning clamping piece 83 to the positioning clamping piece fixed support 82, in this way, the long strip fixed hole 831 and the fixed screw 832 cooperate to determine the position of the positioning clamping piece 83 according to the size of the base / plate 171 of the inductance coil to be tested of different models, thereby improving the production efficiency.

[0053] The connecting end of the positioning clamping piece fixing support 82 and the finger cylinder clamping jaw can be provided with a vertically extending long strip fixing hole 821, and the long strip fixing hole 821 is provided with a fixing screw 822 for fixing the positioning clamping piece fixing support 82 to the finger cylinder clamping jaw. In this way, the long strip fixing hole 821 cooperates with the fixing screw 822 to adjust the height of the positioning clamping piece 83 according to the height of the inductance coil base / plate 171 of different models to be detected, thereby improving production efficiency.

[0054] As shown in Figure 2 and Figure 4 The probe fixing device can include, from bottom to top, a probe adapter plate 88, a probe fixing block 87, and a probe pressing block 86 connected in sequence. The upper surface of the probe fixing block 87 is provided with a probe fixing hole (not shown). When installing the probe 85, the probe 85 is placed on the probe fixing hole reserved on the probe fixing block 87, and the probe 85 can be adjusted to the appropriate position in the reserved hole. Then, the probe pressing block 86 is connected with the probe fixing block 87, so as to press and fix the probe 85.

[0055] The probe fixing block 87 can be provided with a long strip fixing hole 871 extending along the width direction of the test seat 84, and the long strip fixing hole 871 is provided with a fixing screw 872 for fixing the probe fixing block 87 to the probe adapter plate 88.

[0056] The probe adapter plate 88 can be provided with a vertically extending long strip fixing hole 881, and the long strip fixing hole 881 is provided with a fixing screw 882 for fixing the probe adapter plate 88 to the probe adapter fixing support 89.

[0057] The cooperation of the long strip fixing hole 871 and the fixing screw 872 can adjust the distance between the probe head and the PIN pin according to the inductance coil 17 to be detected of different models; the cooperation of the long strip fixing hole 881 and the fixing screw 882 can adjust the probe height to align with the PIN pin according to the inductance coil 17 to be detected of different models. Through the adjustment of the above two groups of long strip fixing holes and fixing screws, the probe can be aligned with the PIN pin of the inductance coil to be tested of any model, which is convenient to use.

[0058] As shown in Figure 5As shown, the probe 85 can sequentially include a probe head 851, a front connecting rod 852 and a rear connecting rod 853 from front to back, a spring (not shown) is arranged between the front connecting rod 852 and the rear connecting rod 853, a connecting pipe 854 is sleeved at the joint of the front connecting rod 852 and the rear connecting rod 853, and the front surface of the probe head 851 is serrated. The spring is arranged between the front connecting rod 852 and the rear connecting rod 853, so that the probe head 851 has a certain range of elasticity. When the probe 85 contacts the PIN pin, the probe head 851 will shrink due to pressure. When the test is completed, the probe 85 returns to the original position, and the probe head 851 will return to the original length. The interaction force between the probe 85 and the PIN pin is not enough to cause the PIN pin to deform. In this way, not only can it ensure that each pin of the inductor to be tested is in good contact with the needle of a different probe, but also it will not affect the subsequent use of the inductor to be tested. The surface of the probe head 851 in contact with the pin of the inductor is serrated, which can replace the original planar point contact with surface contact, thereby increasing the contact area with the pin.

[0059] As shown in Figure 6 , the test seat fixing support 810 can be a pair of opposite arrangements, and the test seat 84 can be detachably connected to the test seat fixing support 810. The test seat 84 serves to support the inductor to be tested 17 from the bottom. The detachable design facilitates the replacement of test seats 84 of different sizes according to the size of the base / plate 171 of the inductor to be tested of different models, and is convenient to use.

[0060] In order to facilitate the replacement of the test seat 84, the test seat 84 can be fixed on the test seat fixing support 810 by screws. At this time, the length direction of the test seat 84 can be provided with screw avoiding grooves 841 at both ends. An electromagnetic coil (not shown) for adsorbing the inductor to be tested 17 can be embedded in the test seat 84. In use, the electromagnetic coil can be started first to adsorb the inductor to be tested 17 on the test seat 84. After the finger cylinder 81 drives the positioning clamp 83, the electromagnetic coil is turned off. In this way, the placing firmness and stability of the inductor to be tested 17 can be enhanced. The width of the test seat 84 can be slightly smaller than the distance between the PIN pins of the inductor to be tested, so as to facilitate the placement of the inductor to be tested 17.

[0061] As shown in Figure 2 , the probe pressing block 86 can be provided with a photoelectric sensor 812 for detecting whether the inductor to be tested 17 exists on the test seat 84. In use, the photoelectric sensor 812 can be used to detect whether the inductor to be tested 17 exists on the test seat 84. After detecting that there is no inductor to be tested 17, the inductor to be tested 17 is placed on the test seat 84, and the finger cylinder 81 drives the positioning clamp 83 to clamp and position the inductor to be tested 17. In this way, the production efficiency can be improved and the failure rate can be reduced.

[0062] It is conceivable that when other models of the inductance coil 17 to be tested are replaced, the positions of the new probe pressing block 86 and the probe fixing block 87 need to be determined according to the PIN distance of the inductance coil 17 to be tested, and if the appearance of the inductance coil 17 to be tested is greatly different, the corresponding test seat 84 also needs to be replaced.
