Description

Technical Field

[0001] The invention relates to the technical field of resistance product testing, and in particular to a device for automatically testing withstand voltage and resistance. Background Art

[0002] At present, high-power resistors on the market need to add aluminum heat sinks to the finished product during design to improve the product's heat dissipation capacity. However, after adding the heat sink, the product is prone to breakdown between the chip and the heat sink, so the product needs to be fully inspected by a withstand voltage test.

[0003] Since the points used in the withstand voltage test are different from those used in the ordinary resistance test, the existing full performance inspection requires manual inspection, which reduces the inspection efficiency. Although there are devices in the prior art that can automatically inspect resistor products, the existing inspection equipment cannot clean the connection between the resistor product and the instrument during inspection. Impurities in the connection between the resistor product will have an adverse effect on the subsequent inspection results. Summary of the invention

[0010] Optionally, a test position is provided at the bottom of the test box, and a through slot is provided at the front of the test box for facilitating insertion of a test end of an external withstand voltage tester.

[0011] Optionally, a partition is installed inside the test box, and two first electric telescopic rods are installed on one outer wall of the test box, and the telescopic ends of the two first electric telescopic rods are connected to one end of the partition located outside the test box.

[0012] Optionally, the auxiliary correction mechanism includes a movable plate arranged inside the equipment body, with two grooves formed on the top of the movable plate, double-headed screws rotatably installed inside the two grooves, two movable blocks symmetrically installed on the outer walls of the two double-headed screws, and splints installed on the tops of the two movable blocks.

[0014] Optionally, the cleaning mechanism includes two fourth slide grooves opened on the inner wall of one side of the test box, fourth sliders are installed inside the two fourth slide grooves, and a mounting plate is commonly installed at one end of the two fourth sliders away from the fourth slide grooves.

[0015] Optionally, a second electric telescopic rod is rotatably mounted on an outer wall of one side of the mounting plate away from the two fourth sliding blocks, a rotating plate is mounted at the telescopic end of the second electric telescopic rod, and a cleaning pad is mounted on an outer wall of the rotating plate away from the second electric telescopic rod.

[0017] 1. In the invention, the device can be directly placed in the test box during the transfer stage of the product body, and the product body can be fully inspected for voltage resistance and defective products can be distinguished. In addition, the resistance value can be fully inspected on the same device, reducing product inspection costs and increasing product inspection efficiency.

[0019] 3. In the invention, after cleaning the heat dissipation aluminum sheet on the outer wall of the product body, the telescopic end of the second electric telescopic rod continues to be controlled to be in an extended state, and is abutted against the outer wall of the product body by means of the rotating plate. In the process of the product body moving downward, the two fourth sliders are used to slowly move downward, thereby driving the rotating plate and the product body to move slowly downward together, so as to facilitate the flexible falling of the product body inside the test box and avoid the problem that the product body falls quickly inside the test box, causing its external shell and pins to collide with the inner wall of the test box, which is easy to be damaged.

[0020] 4. In the present invention, since a third slide groove is provided on the outer wall on the other side of the equipment body, if the first driving mechanism fails during use, after the pins of the upper product body are clamped and fixed by means of two clamps, the third slider is moved inside the third slide groove toward the direction close to the test box, and the product body at the right end is pushed into the test box for testing, thereby reducing the adverse effects caused by the failure of the first driving mechanism and avoiding affecting the test progress and test results of the product body.

Two second drive motors are preset inside the moving plate 21, and the output ends of the two second drive motors are respectively used to connect with one end of the two double-headed screws 24, so as to drive the two double-headed screws 24 to rotate inside the corresponding grooves 23, so that the two corresponding moving blocks can move towards or away from the outer wall of the double-headed screw 24, and drive the two clamping plates 22 to move towards or away from each other; and a soft pad is preset on the outer wall of the side where the two clamping plates 22 are close to each other, which can flexibly contact with the bottom pin 17 of the product body 1.

[0042] As a technical optimization solution of the present invention, the cleaning mechanism includes two fourth chutes 31 opened on the inner wall of one side of the test box 3, and the fourth sliders 34 are installed inside the two fourth chutes 31, and the mounting plate 32 is installed together at one end of the two fourth sliders 34 away from the fourth chutes 31. A fourth linear motor is preset inside the two fourth chutes 31, and the fourth linear motor can drive the fourth slider 34 to move up and down inside the fourth chutes 31, and drive the mounting plate 32 to move up and down inside the test box 3.

[0043] As a technical optimization solution of the present invention, a second electric telescopic rod 35 is rotatably mounted on the outer wall of the mounting plate 32 away from the two fourth sliders 34, a rotating plate 33 is mounted on the telescopic end of the second electric telescopic rod 35, and a cleaning pad is mounted on the outer wall of the rotating plate 33 away from the second electric telescopic rod 35. A fourth driving motor is preset at the center of the mounting plate 32, and the output end of the first driving motor is connected to the second electric telescopic rod 35, so that the second electric telescopic rod 35 and the rotating plate 33 can be driven to rotate together.

[0044] In the present invention, when the user uses the device, the multiple product bodies 1 are placed in the slot from the left end of the device body 2 in sequence, and are pushed toward the right end by means of the first driving mechanism. The push rod head 26 moves along with the first slider 27 inside the first slide groove 8, and the multiple product bodies 1 are pushed forward one by one to fall into the inside of the test box 3; the product bodies 1 that fall into the inside of the test box 3 can fall downward into the test card position 6, and an elastic metal sheet is preset inside the test card position 6. After one of the test ends of the externally preset withstand voltage tester is connected to it, the other test end of the withstand voltage tester is connected to the test card position 6. The end passes through the through slot 7 and contacts the heat dissipation aluminum sheet arranged on the outer wall of the product body 1 for testing; if there is no problem with the product body 1 inside the test box 3 after the inspection, one of the telescopic ends of the electric push rods 5 can be extended to drive one of the push blocks 16 to push it out from the inside of the test box 3; if there is a problem with the product body 1 after the inspection, the test box 3 can be controlled to move forward to a position close to the other electric push rod 5, and the telescopic end of the other electric push rod 5 can be extended to drive the other push block 16 to push it out from the inside of the test box 3, so as to achieve the effect of separating qualified and unqualified products.

[0045] If it is necessary to test the resistance of the product body, the test end of the external preset resistance tester can be connected to the elastic metal sheet inside the test card position 6, and the test card position 6 can be used for resistance testing; through this equipment, the product body 1 can be directly placed in the test box 3 during the transportation stage, and the product body 1 can be fully inspected for withstand voltage and defective products can be distinguished, and full resistance inspection can be achieved on the same device, reducing product inspection costs and increasing product inspection efficiency.

[0046] When the product body 1 is placed from the left end of the slot to the inside of the device body 2 in sequence, the product body 1 at this time falls on the telescopic end surface of the third electric telescopic rod extending from the left end of the two protrusions 15, and the pin 17 contacts the top of the movable plate 21. The two clamping plates 22 can be controlled to move in a direction close to each other to perform auxiliary shaping processing on the pin 17, thereby avoiding the problem that the subsequent pin 17 cannot accurately fall into the test position 6 for detection due to the deformation of the bottom pin 17 of the product body 1 before detection. The accuracy of the pin 17 falling into the test position 6 is improved, and the test efficiency of the product body 1 can also be indirectly improved.

[0047] After the two clamps 22 have shaped and corrected the pin 17, the driving screw 12 can be controlled to drive the movable plate 21 to move downward, and the two clamps 22 can be driven to move downward synchronously, so that the soft pads set on the outer walls of one side of the two clamps 22 can rub the outer wall of the pin 17, so that the debris attached to the outer wall of the pin 17 can be cleaned and removed, which facilitates the subsequent contact between the pin 17 and the elastic metal sheet, thereby reducing the short circuit during the testing of the pin 17.

[0048] If the pin 17 at the bottom of the product body 1 is deformed to a large extent and cannot be reshaped and corrected with the help of the two clamps 22, the third electric telescopic end preset inside the two protrusions 15 can be controlled to retract, thereby driving the product body 1 to fall downward to the top of the movable plate 21, so that it is automatically discharged downward from the inside of the equipment body 2, thereby facilitating the automatic removal of product bodies 1 with surface defects and avoiding affecting the inspection efficiency of other product bodies 1.

[0049] When the product body 1 is pushed from the inside of the equipment body 2 into the inside of the test box 3 with the help of the first driving mechanism, the product body 1 falls on the top of the partition 29, controlling the extension of the telescopic end of the second electric telescopic rod 35, driving the rotating plate 33 to move in the direction close to the product body 1, so that the cleaning pad set on the outer wall of one side of the rotating plate 33 contacts the heat dissipation aluminum fin to be tested later on the product body 1, and the rotating plate 33 is driven to rotate together with the help of the second electric telescopic rod 35, so as to rotate and clean the outer wall of the heat dissipation aluminum fin, so as to facilitate the subsequent contact between the other test end of the withstand voltage tester and the heat dissipation aluminum fin, thereby reducing the influence of debris on the contact test between the test end and the heat dissipation aluminum fin.

[0050] After cleaning the heat dissipation aluminum sheet on the outer wall of the product body 1, the telescopic end of the second electric telescopic rod 35 can continue to be controlled to be in an extended state, and the rotating plate 33 can be used to abut against the outer wall of the product body 1 to limit the abutment of the product body 1. The telescopic ends of the two first electric telescopic rods 14 are extended to drive the partition 29 to move out from the inside of the test box 3. At this time, the bottom end of the product body 1 loses support and can be used to slowly move downward inside the fourth slide groove 31 with the help of two fourth sliders 34, thereby driving the rotating plate 33 and the product body 1 to move slowly downward together until the pin 17 enters the inside of the test position 6, so that the product body 1 can fall flexibly inside the test box 3, avoiding the problem that the product body 1 falls quickly inside the test box 3, causing its external shell and pin 17 to collide with the inner wall of the test box 3, and it is easy to be damaged.

[0051] Since a third slide groove 13 is provided on the outer wall on the other side of the device body 2, if the first driving mechanism fails during use and the product body 1 inside the device body 2 cannot be pushed and transported to the inside of the test box 3 for testing, the pins 17 of the upper product body 1 can be clamped and fixed by means of two clamping plates 22, and then the third slider 18 can be used to move inside the third slide groove 13 toward the direction close to the test box 3, so as to push the product body 1 at the right end into the inside of the test box 3 for testing, thereby reducing the adverse effects caused by the failure of the first driving mechanism and avoiding affecting the test progress and test results of the product body 1.

[0052] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
