Description

Technical Field

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

[0002] At present, high-power resistors on the market need to add aluminum heat sinks to the finished products during design to improve the heat dissipation capacity of the products. However, after adding the heat sinks, there is a potential risk of breakdown between the chip and the heat sink in the product, so it is necessary to conduct a full inspection of the withstand voltage test on the product.

[0003] Since the points used for the withstand voltage test and the ordinary resistance value test are inconsistent, manual inspection is required for the existing performance full inspection, which reduces the inspection efficiency; although there are also devices in the prior art that can automatically detect resistance products, the existing detection devices cannot clean the connection parts between the resistance products and the instruments during detection, and the impurities at the connection parts of the resistance products will have an adverse impact on the subsequent detection results. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose a device for automatically testing withstand voltage and resistance value.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0006] A device for automatically testing withstand voltage and resistance value, including a plurality of product bodies and a device body. The plurality of product bodies are all placed in the slot positions opened inside the device body. One end of the device body is provided with a test box. A first driving mechanism for driving the plurality of product bodies to sequentially enter the test box for testing is installed on the outer wall of one side of the device body. A cleaning mechanism for cleaning the outer wall of the product body is installed inside the test box. Pins are installed at the bottom ends of the plurality of product bodies. An auxiliary correction mechanism for correcting the deformed pins is arranged inside the device body. A second driving mechanism for driving the auxiliary correction mechanism to move back and forth inside the device body is installed on the outer wall of the other side of the device body.

[0007] Optionally, the first driving mechanism includes a first sliding groove opened on the outer wall of one side of the device body. A first sliding block is installed inside the first sliding groove. One end of the first sliding block away from the first sliding groove is rotatably installed with a rotating block. The top end of the rotating block is rotatably installed with a movable push rod. One end of the movable push rod away from the rotating block is installed with a push rod head.

[0008] Optionally, two convex blocks are installed on the inner walls of both sides of the device body. A bottom plate is installed at the bottom end of the device body. Two second sliding grooves are opened on the top of the bottom plate. Two second sliding blocks that can move back and forth inside the second sliding grooves are installed at the bottom end of the test box.

[0009] Optionally, a fixing frame is installed on the outer wall of one side of the bottom plate close to the equipment body. Two electric push rods are installed on the outer wall of one side of the two fixing frames close to the bottom plate, and push blocks are installed at the telescopic ends of the two electric push rods.

[0010] Optionally, a test clamping position is opened at the bottom end of the test box, and a through groove for the insertion of the test end of an external withstand voltage tester is opened on the front surface of the test box.

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

[0012] Optionally, the auxiliary correction mechanism includes a moving plate arranged inside the equipment body. Two grooves are opened at the top of the moving plate. Two double-headed screws are rotatably installed inside the two grooves. Two moving blocks are symmetrically installed on the outer walls of the two double-headed screws, and clamping plates are installed at the top ends of the two moving blocks.

[0013] Optionally, the second driving mechanism includes a third sliding groove opened on the outer wall of the other side of the equipment body. A third sliding block is installed inside the third sliding groove. One end of the third sliding block away from the third sliding groove is installed with a mounting block. A driving lead screw and a sliding rod are rotatably installed at the bottom end of the mounting block. A sliding plate is installed on the outer wall of the moving plate close to the third sliding groove. The sliding rod is matched with the outer walls of the driving lead screw and the sliding rod.

[0014] Optionally, the cleaning mechanism includes two fourth sliding grooves opened on the inner wall of one side of the test box. Fourth sliding blocks are installed inside the two fourth sliding grooves. One end of the two fourth sliding blocks away from the fourth sliding grooves is jointly installed with a mounting plate.

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

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. In this invention, through this equipment, the product body can be directly placed into the test box during the transfer stage, the product body can be subjected to a full withstand voltage inspection and defective products can be distinguished, and a full resistance inspection can be realized on the same equipment, reducing the product inspection cost and increasing the product detection efficiency.

[0018] 2. In the invention, after the two clamps correct the shaping of the pins, the driving screw is controlled to drive the movable plate to move downward, so that the soft pads arranged on the outer wall of one side of the two clamps close to each other rub against the outer wall of the pin, and the debris attached to the outer wall of the pin is cleaned and removed, so as to facilitate the subsequent contact between the pin and the elastic metal sheet and reduce the short circuit during the pin testing process; in conjunction with the cleaning mechanism arranged inside the test box, the heat dissipation aluminum sheet arranged on the outer wall of the product body can be cleaned, so as to reduce the influence of debris on the contact test between the test end and the heat dissipation aluminum sheet.

[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.

After the push rod head 26 rotates to abut against one of the product bodies 1, the first slider 27 moves inside the first sliding groove 8 towards the direction of the test box 3, and then pushes multiple product bodies 1 to move inside the equipment body 2.

[0036] As a technical optimization solution of the present invention, two convex blocks 15 are installed on the inner walls of both sides of the equipment body 2. A bottom plate 9 is installed at the bottom end of the equipment body 2. Two second sliding grooves 10 are opened on the top of the bottom plate 9.

[0037] As a technical optimization solution of the present invention, a fixing frame 11 is installed on the outer wall of the bottom plate 9 close to the equipment body 2. Two electric push rods 5 are installed on the outer wall of the two fixing frames 11 close to the bottom plate 9. Push blocks 16 are installed at the telescopic ends of the two electric push rods 5.

An elastic metal sheet is preset inside the test slot 6. After connecting one of the test ends of the externally preset withstand voltage tester thereto, the other test end of the withstand voltage tester is passed through the through slot 7 and contacted with the heat dissipation aluminum sheet provided on the outer wall of the product body 1 for testing; if it is necessary to test the resistance of the product body 1, the test end of the externally preset resistance tester can be connected to the elastic metal sheet inside the test slot 6, and the test slot 6 can be used for resistance testing.

[0040] As a technical optimization solution of the present invention, the auxiliary correction mechanism includes a moving plate 21 provided inside the equipment body 2. Two grooves 23 are provided at the top of the moving plate 21. Two double-headed screws 24 are rotatably installed inside the two grooves 23. Two moving blocks are symmetrically installed on the outer walls of the two double-headed screws 24, and clamping plates 22 are installed at the top ends of the two moving blocks. 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 be connected to 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 toward or away from each other on the outer walls of the double-headed screws 24, and drive the two clamping plates 22 to move toward or away from each other accordingly; and soft pads are preset on the outer walls of the two clamping plates 22 on the side close to each other, which can be in flexible contact with the bottom pins 17 of the product body 1.

[0041] As a technical optimization solution of the present invention, the second driving mechanism includes a third sliding groove 13 opened on the outer wall of the other side of the equipment body 2. A third slider 18 is installed inside the third sliding groove 13. One end of the third slider 18 away from the third sliding groove 13 is installed with a mounting block 19. A driving lead screw 12 and a sliding rod 20 are rotatably installed at the bottom end of the mounting block 19. A sliding plate 25 is installed on the outer wall of the moving plate 21 close to the third sliding groove 13. The sliding rod is matched with the outer walls of the driving lead screw 12 and the sliding rod 20. A third linear motor is preset inside the third sliding groove 13, and the third linear motor can drive the third slider 18 to move back and forth inside the third sliding groove 13; a third driving motor is preset inside the mounting block 19, and the output end of the third driving motor is connected to the top end of the driving lead screw 12, so as to drive the driving lead screw 12 to rotate, and then drive the sliding plate 25 and the moving plate 21 to move up and down.

[0042] As a technical optimization solution of the present invention, the cleaning mechanism includes two fourth sliding grooves 31 opened on one inner wall of the test box 3. Fourth sliders 34 are installed inside the two fourth sliding grooves 31. One end of the two fourth sliders 34 away from the fourth sliding grooves 31 is jointly installed with a mounting plate 32. Fourth linear motors are preset inside the two fourth sliding grooves 31, and the fourth linear motors can drive the fourth sliders 34 to move up and down inside the fourth sliding grooves 31, and then 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 installed on the outer wall of the mounting plate 32 away from the two fourth sliders 34. A rotating plate 33 is installed at the telescopic end of the second electric telescopic rod 35. A cleaning pad is installed 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 central position inside the mounting plate 32, and the output end of the first driving motor is connected to the second electric telescopic rod 35, so as to drive the second electric telescopic rod 35 and the rotating plate 33 to rotate together.

[0044] In the present invention, when the user uses the device, a plurality of product bodies 1 are sequentially placed in the slots from the left end of the device body 2, and are pushed towards the right end by means of the first driving mechanism. The push rod head 26 moves inside the first chute 8 along with the first slider 27, pushing the plurality of product bodies 1 forward one by one so that they fall into the interior of the test box 3; the product bodies 1 that fall into the interior of the test box 3 can then fall downward into the test positions 6. An elastic metal sheet is preset inside the test positions 6. After connecting one of the test ends of a preset external withstand voltage tester thereto, the other test end of the withstand voltage tester is passed through the through slot 7 and contacted with the heat dissipation aluminum sheet provided 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 detection, one of the electric push rods 5 can be extended at its telescopic end to drive one of the push blocks 16 to push it out of the interior of the test box 3; if there is a problem with the product body 1 after detection, the test box 3 can be controlled to move forward to a position close to the other electric push rod 5, and the other electric push rod 5 is extended at its telescopic end to drive the other push block 16 to push it out of the interior of the test box 3, achieving the effect of separating and discharging qualified and unqualified products.

[0045] If it is necessary to test the resistance of the product body, the test end of a preset external resistance tester can be connected to the elastic metal sheet inside the test position 6, and the test position 6 can be used for resistance testing; through this device, the product body 1 can be directly placed into the test box 3 during the transfer stage, the product body 1 can be subjected to a full withstand voltage inspection and defective products can be distinguished, and a full resistance value inspection can be realized on the same device, reducing the product inspection cost and increasing the product detection efficiency.

[0046] When the product body 1 is sequentially placed into the interior of the device body 2 from the left end of the slot, at this time, the product body 1 falls onto the surface of the telescopic end of the third electric telescopic rod extending from the left end of the two bumps 15, and the pin 17 contacts the top of the moving plate 21. By controlling the two clamping plates 22 to move towards each other, auxiliary shaping treatment can be performed on the pin 17, 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, improving the accuracy of the subsequent fall of the pin 17 into the test position 6, and indirectly improving the test efficiency of the product body 1.

[0047] After the two clamping plates 22 correct the shaping of the pin 17, the driving screw rod 12 can be controlled to drive the moving plate 21 to move downward. During the synchronous downward movement of the two clamping plates 22, the soft pads provided on the outer walls of the two clamping plates 22 on the side close to each other rub the outer wall of the pin 17 to clean and remove the debris attached to the outer wall of the pin 17, facilitating the subsequent contact between the pin 17 and the elastic metal sheet and reducing the occurrence of short circuits during the testing of the pin 17.

[0048] If the deformation amplitude of the pin 17 at the bottom of the product body 1 is relatively large and it cannot be rectified by means of the two clamping plates 22, the third electric telescopic ends preset inside the two bumps 15 can be controlled to retract, driving the product body 1 to fall downward onto the top of the moving plate 21, so that it automatically discharges downward from the inside of the equipment body 2, thus facilitating the automatic rejection of the product body 1 with surface defects and avoiding affecting the detection efficiency of other product bodies 1.

[0049] When the product body 1 is pushed into the inside of the test box 3 from the inside of the equipment body 2 by means of the first driving mechanism, the product body 1 falls onto the top of the partition plate 29. The telescopic end of the second electric telescopic rod 35 is controlled to extend, driving the rotating plate 33 to move towards the product body 1, so that the cleaning pad arranged on the outer wall of one side of the rotating plate 33 contacts the heat dissipation aluminum sheet to be tested later on the product body 1. The rotating plate 33 is driven by the second electric telescopic rod 35 to rotate together, and the outer wall of the heat dissipation aluminum sheet is rotated and cleaned accordingly, facilitating the contact between the other test end of the subsequent withstand voltage tester and the heat dissipation aluminum sheet and reducing the influence of sundries on the contact test between the test end and the heat dissipation aluminum sheet.

[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 be continuously controlled to be in the extended state. By means of the rotating plate 33 abutting against the outer wall of the product body 1, the product body 1 is abutted and limited. The telescopic ends of the two first electric telescopic rods 14 are extended to drive the partition plate 29 to move out of the inside of the test box 3. At this time, the bottom end of the product body 1 loses support, and the two fourth sliders 34 can be used to slowly move downward inside the fourth chute 31, driving the rotating plate 33 and the product body 1 to move downward slowly together until the pin 17 enters the inside of the test position 6, which is convenient for the product body 1 to fall flexibly inside the test box 3 and avoid the problem that the product body 1 falls rapidly inside the test box 3, resulting in the impact between its outer shell and the pin 17 and the inner wall of the test box 3, which is easy to damage.

[0051] Since there is a third chute 13 on the outer wall of the other side of the equipment body 2, if the first driving mechanism fails during use and cannot push and convey the product body 1 inside the equipment body 2 into the inside of the test box 3 for detection, the two clamping plates 22 can be used to clamp and fix the pin 17 of the upper product body 1, and then the third slider 18 is used to move inside the third chute 13 towards the test box 3, and the product body 1 at the right end is pushed into the inside of the test box 3 for testing, reducing the adverse impact brought 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 embodiments described. Obviously, many modifications and variations can be made according to the content of this specification. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of the present invention, so that those skilled in the art can well understand and utilize the present invention.
