[0023] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] like Figure 1-4 As shown, an inductor sheet withstand voltage testing device includes a testing platform 1 and a testing unit 2 disposed on the testing platform 1. The top of the testing platform 1 is provided with a mounting groove 11, and a lead screw 13 driven by a motor 12 is disposed in the mounting groove 11. A slider 14 is also adaptedly disposed in the mounting groove 11. The lead screw 13 passes through the slider 14 and is threadedly connected to the slider 14. The top of the testing platform 1 is also provided with a feeding unit 3 and a push plate 4. The top of the slider 14 is connected to the bottom of the push plate 4. The feeding unit 3 is provided with a plurality of inductor sheets 5 stacked vertically. The push plate 4 is used to push the inductor sheets 5 toward the testing unit 2. The testing unit 2 is used to perform withstand voltage testing on the inductor sheets 5.

[0025] The feeding unit 3 lowers the guide plate 5 to be tested onto the top of the testing table 1. Then, the motor 12 drives the lead screw 13 to rotate. Since the lead screw 13 and the slider 14 are connected by threads, and the outer wall of the square slider 14 fits against the inner wall of the mounting groove 11, the rotation of the lead screw 13 can drive the slider 14 to slide in the mounting groove 11, thereby driving the push plate 4 to move along the extension direction of the mounting groove 11. In this way, the push plate 4 can push the guide plate 5 towards the testing unit 2. After the guide plate 5 moves to the bottom of the testing unit 2, the testing unit 2 can perform a pressure resistance test on the guide plate 5. After the test is completed, the push plate 4 can push the guide plate 5 away from the testing unit 2 to achieve post-test discharge. Only manual discharge of the guide plate 5 into the feeding unit 3 is required, and the remaining steps do not require manual intervention, greatly improving the testing efficiency.

[0026] The detection unit 2 includes a vertical plate 21, a movable plate 22, and a detection head 23. The vertical plate 21 is located outside the mounting groove 11. The movable plate 22 is placed horizontally and is attached to one side of the vertical plate 21. The detection head 23 is located at the bottom of the movable plate 22 and above the mounting groove 11. The vertical plate 21 has a vertically extending groove 211. A connecting rod 212 is provided in the groove 211. One end of the connecting rod 212 is connected to the movable plate 22, and the other end of the connecting rod 212 passes through the groove 211 and extends to the other side of the vertical plate 21. A hydraulic cylinder 213 is provided on the other side of the vertical plate 21. The push rod of the hydraulic cylinder 213 is connected to the other end of the connecting rod 212. The hydraulic cylinder 213 is used to drive the connecting rod 212 and the movable plate 22 to reciprocate vertically.

[0027] When the guide plate 5 to be tested is moved below the movable plate 22, the hydraulic cylinder 213 drives the connecting rod 212 and the movable plate 22 to move downward, so that the detection head 23 contacts the guide plate 5, thereby completing the detection operation. After the detection is completed, the hydraulic cylinder 213 drives the movable plate 22 and the detection head 23 to reset, which facilitates the discharge of the detected guide plate 5 and the introduction of a new guide plate 5 to be tested.

[0028] Each end of the mounting groove 11 is provided with a bearing seat 15, and the two ends of the lead screw 13 are respectively and correspondingly inserted into the two bearing seats 15; the outer side of the testing table 1 is provided with a mounting platform 16, and the motor 12 is fixed on the mounting platform 16. The output shaft of the motor 12 is connected to the lead screw 13. In this way, the motor 12 can be in a reliable working state. At the same time, under the action of the two bearing seats 15, the motor 12 can reliably drive the lead screw 13 to rotate.

[0029] The top of the inspection table 1 is equipped with two inspection units 2, which are respectively located on both sides of the unloading unit 3. The unloading unit 3 and the two inspection units 2 are arranged at intervals along the same straight line. When the push plate 4 pushes a guide plate 5 to a position below one inspection unit 2, while the inspection unit 2 is inspecting the guide plate 5, the push plate 4 moves in the opposite direction, thereby pushing another guide plate 5 to a position below another inspection unit 2, shortening the waiting time of the push plate 4 and further improving the inspection efficiency.

[0030] The feeding unit 3 includes a feeding tube 31 with a notch 310 at its lower part. Several guide plates 5 are stacked vertically inside the feeding tube 31. The guide plates 5 can slide out of the feeding tube 31 through the notch 310 along the extension direction of the mounting groove 11. The outer wall of the guide plate 5 fits against the inner wall of the feeding tube 31. The height of the notch 310 is greater than the thickness of a single guide plate 5 but less than the sum of the thicknesses of two guide plates 5. The height of the push plate 4 is less than the thickness of a single guide plate 5. Because the feeding tube 31 has a notch 310 at its bottom, when the guide plate 5 is placed inside the feeding tube 31, the bottommost guide plate 5 will contact the top of the detection table 1. Furthermore, because the height of the notch 310 is between 1 and 2 times the thickness of the guide plate 5, the push plate 4 can push only one guide plate 5 out of the feeding tube 31 at a time, ensuring that several guide plates 5 can be pushed sequentially by the push plate 4 to the bottom of the two detection units 2. The notch 310 extends through the feed pipe 31 along the length of the mounting groove 11. In this way, when the push plate 4 moves in the forward direction and pushes a guide plate 5 to a detection unit 2, the push plate 4 can move in the reverse direction to push another guide plate 5 to another detection unit 2. The overall process is smooth and the detection effect is improved.

[0031] The top of the testing station 1 is also equipped with two first discharge troughs 17 and two second discharge troughs 18. The two first discharge troughs 17 are located at both ends of the mounting groove 11, and are used to discharge the guide pieces 5 that have passed the test. The two second discharge troughs 18 are located at both ends of the mounting groove 11, and are used to discharge the guide pieces 5 that have failed the test. The first discharge troughs 17 and the second discharge troughs 18 located at the same end of the mounting groove 11 are located on both sides of the mounting groove 11. That is to say, each testing unit 2 has a first discharge trough 17 and a second discharge trough 18 on its outer side. The guide pieces 5 can be pushed into the first discharge troughs 17 and the second discharge troughs 18 according to the test results, which facilitates the classification and collection of the guide pieces 5.

[0032] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
