Abstract
Description
Technical Field
[0001] This application relates to the technical field of transformer testing components, and in particular to a comprehensive transformer testing device. Background Technology
[0002] Transformers are widely used components in the electronics industry. Transformer testing is an important step in ensuring the normal operation and performance evaluation of transformers. However, transformers need to undergo multiple testing procedures before and after their manufacture.
[0003] The existing announcement number CN220568842U, entitled "A Circuit Board Testing Fixture," relates to the field of testing fixture technology. It includes a base and a base plate fixedly mounted on one side of the top of the base. A fixing seat is fixedly mounted on the front of the base plate, and an electric push rod is fixedly mounted on the fixing seat. An inverted T-shaped movable plate is fixedly mounted on the output end of the electric push rod. A testing module is mounted on one side of the bottom of the movable plate, and a testing platform is mounted on the base directly below the testing module. This utility model has a reasonable design structure. When a circuit board needs to be tested, the circuit board is placed in the placement slot. Then, two screw blocks are turned half a turn. The rotation of the screw blocks drives the eccentric wheel to rotate. When the eccentric wheel rotates, it exerts a pushing force on the clamping plate, causing the clamping plate to move under force. Thus, the two clamping plates can limit and fix the circuit board in the placement slot, thereby improving the accuracy of the placement position during the circuit board testing process and reducing the possibility of inaccurate data due to circuit board position deviation.
[0004] Regarding the aforementioned technologies, the inventors discovered that the fixed size and structure of the testing fixture allows for the testing of transformer circuit boards of a single size only. When it is necessary to test circuit boards of different sizes later, the fixture needs to be disassembled and replaced with a fixture of a suitable size. This process requires frequent disassembly and replacement of various tools, resulting in low transformer testing efficiency and a decrease in production efficiency. Utility Model Content
[0005] To overcome the problem that existing single-size transformer testing fixtures require disassembling the fixture and replacing it with a fixture of a suitable size when testing circuit boards of different sizes, which involves frequent disassembly and replacement of various tools such as fixtures, resulting in low transformer testing efficiency and reduced production efficiency, this application provides a comprehensive transformer testing device.
[0006] The transformer comprehensive testing device provided in this application adopts the following technical solution:
[0007] A transformer integrated testing device includes a frame, a feeding conveyor, a discharging conveyor, a clamping component, and fixtures. A lower storage box is fixed to the bottom of the frame, and various testing devices are installed in the lower storage box. An upper storage box is fixed to the top of the frame, and a clamping component is installed on the rear end face of the frame. A feeding conveyor is horizontally installed on one side of the frame, and a discharging conveyor is horizontally installed on the other side of the frame. Multiple partitions are horizontally and vertically fixed on the frame, and two fixtures are symmetrically arranged between the partitions on the top surface of the frame. Multiple pin holes of various specifications are opened through the top surface of the fixtures, and the fixtures are hollow inside. A sliding plate is horizontally slidably assembled in the hollow cavity of the fixtures, and multiple pin clamping holes of various specifications are opened through the top surface of the sliding plate. Multiple testing pins are fixed through the lower storage box on the bottom surface of the fixtures, and the testing pins are electrically connected to the testing devices in the lower storage box. The bottom surface of the sliding plate is electrically connected to the multiple testing pins through wires.
[0008] By adopting the above technical solution, the finished transformer to be tested is transported towards the frame via a feeding conveyor on one side of the frame. The transformer circuit board to be tested is then clamped and transported onto the fixture on the frame. The pins of the transformer circuit board penetrate the matching pin holes on the top surface of the fixture and are inserted into the hollow cavity of the fixture. Then, the pins of the transformer circuit board are inserted into the pin clamping holes of the sliding plate. The sliding plate is then moved laterally within the hollow cavity of the fixture, causing the pin clamping holes to press against the pins of the transformer circuit board to ensure electrical connection. Finally, the testing equipment in the lower storage box is used... The test pins on the bottom of the fixture are electrically connected to test the transformer circuit board. If the transformer circuit board passes the test, it is clamped onto the discharge conveyor using a clamping device. If it fails, it is clamped onto the non-conforming station using the clamping device. The multiple specifications of pin clamping holes and pin top holes on the fixture and slide plate are adapted to the pin testing requirements of different specifications of transformer circuit boards. It is not necessary to disassemble the fixture and replace it with a fixture of appropriate size. This avoids the need to frequently disassemble and change fixtures and other tools during the production process, thereby improving the efficiency of transformer testing and ensuring production efficiency.
[0009] Optionally, multiple elastic frames are vertically fixed to one end face of the skateboard, and the other vertical end face of the multiple elastic frames is fixed to the inner wall of the hollow cavity of the fixture.
[0010] By adopting the above technical solution, multiple elastic frames are fixed on one end face of the slide plate. The vertical end faces of the multiple elastic frames press against the inner wall of the hollow cavity of the fixture. The deformation force generated by the multiple elastic frames pushes the slide plate to slide in the inner wall of the hollow cavity of the fixture, which facilitates the later recovery of the slide plate in the inner wall of the hollow cavity of the fixture. This is used to press and hold the transformer circuit board pins to keep them stable in the fixture.
[0011] Optionally, a top block is horizontally fixed on the other end face of the slide plate, and the top block is set through one end face of the fixture.
[0012] By adopting the above technical solution, a top block that is horizontally fixed through the side end face of the slide plate is used to press the slide plate laterally in the hollow cavity of the fixture, thereby driving the pin clamp hole to press against the pins of the transformer circuit board to ensure electrical connection.
[0013] Optionally, pneumatic cylinders are horizontally fixed at one end of the fixture on the frame, and the output end of the pneumatic cylinders presses against the top block of the slide plate.
[0014] By adopting the above technical solution, the top block at the output end of the pneumatic cylinder is activated to press against the end of the sliding plate, pushing the pressing sliding plate to move laterally in the hollow cavity of the fixture.
[0015] Optionally, the clamping component includes a first slide frame, which is horizontally fixed to the rear end face of the frame, and a first slide block is horizontally slidably assembled in the first slide frame, and a second slide frame is vertically fixed on the top surface of the first slide block.
[0016] By adopting the above technical solution, the first slide block slides horizontally in the first slide frame, and laterally switches the horizontal position of the clamping and testing transformer circuit board.
[0017] Optionally, a second slide block is vertically slidably assembled in the second slide frame, and a pneumatic gripper is vertically fixed on the bottom surface of the second slide block.
[0018] By adopting the above technical solution, the second slide block moves horizontally in the second slide frame and vertically switches the horizontal position of the transformer circuit board to be clamped, and the transformer circuit board is clamped by pneumatic grippers.
[0019] Optionally, a first screw is horizontally rotatably connected inside the first slide frame, and the first screw thread passes through the bottom surface of the first slide block. A first servo motor is horizontally fixed on one end face of the first slide frame, and the output end of the first servo motor is fixed to the end of the first screw.
[0020] By adopting the above technical solution, the first servo motor is started to drive the first screw to rotate. The rotation of the first screw drives the first slide block to move horizontally in the first slide frame, and the horizontal position of the clamping and detection transformer circuit board is switched laterally.
[0021] Optionally, a second screw is vertically rotatably connected inside the second slide frame, and the second screw is threaded through and assembled on the second slide block. A second servo motor is vertically fixed on the top surface of the second slide frame, and the output end of the second servo motor is fixed to the side of the second screw.
[0022] By adopting the above technical solution, the second servo motor is started to drive the second screw to rotate. The rotation of the second screw drives the second slide block to move vertically and horizontally in the second slide frame, and the horizontal position of the clamping and detection transformer circuit board is switched laterally.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] During operation, the finished transformer to be tested is transported towards the frame via a feeding conveyor on one side of the frame. The transformer circuit board to be tested is then clamped and transported onto the fixture on the frame using clamping components. The pins of the transformer circuit board pass through the matching pin top holes on the top surface of the fixture and are inserted into the hollow cavity of the fixture. The pins are then inserted into the pin clamping holes of the slide plate. The slide plate is then moved laterally within the hollow cavity of the fixture, causing the pin clamping holes to press against the pins of the transformer circuit board to ensure electrical connection. The testing equipment in the lower storage box is then electrically connected to the testing pins on the bottom surface of the fixture to test the transformer circuit board. If the transformer circuit board passes the test, it is clamped onto the discharge conveyor using clamping components. If it fails, it is clamped to the non-conforming station using clamping components. The multiple specifications of pin clamping holes and pin top holes on the fixture and slide plate accommodate the pin testing needs of different specifications of transformer circuit boards, eliminating the need to disassemble the fixture and replace it with a suitable size fixture. This avoids frequent changes of fixtures and other tools during production, thereby improving transformer testing efficiency and ensuring production efficiency. Attached Figure Description

Detailed Implementation
[0031] The present application will be further described in detail below with reference to the accompanying drawings.
[0032] This application discloses a comprehensive transformer testing device. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A transformer integrated testing device includes a frame 1, a feeding conveyor 2, a discharging conveyor 3, a clamping member 4, and a fixture 5. A lower storage box 14 is fixed to the bottom of the frame 1, and various testing devices are installed in the lower storage box 14. An upper storage box 13 is fixed to the top of the frame 1, and the clamping member 4 is installed on the rear end face of the frame 1. The feeding conveyor 2 is horizontally installed on one side of the frame 1, and the discharging conveyor 3 is horizontally installed on the other side of the frame 1. Multiple partitions 11 are horizontally and vertically fixed on the frame 1, and the top surface of the frame 1 is covered by multiple partitions. Two fixtures 5 are symmetrically arranged between each of the 11 fixtures. The top surface of each fixture 5 has multiple pin holes 51 of various specifications. The interior of each fixture 5 is hollow. A slide plate 52 is horizontally slidably assembled in the hollow cavity of the fixture 5. The top surface of the slide plate 52 has multiple pin clamping holes 54 of various specifications. The bottom surface of each fixture 5 has a lower storage box 14 through which multiple detection pins 56 are fixed. The detection pins 56 are electrically connected to the detection equipment in the lower storage box 14. The bottom surface of the slide plate 52 is electrically connected to the multiple detection pins 56 through wires.
[0033] By adopting the above technical solution, the finished transformer to be tested is transported towards the frame 1 via the feeding conveyor 2 on one side of the frame 1. Then, the transformer circuit board to be tested is clamped and transported onto the fixture of the frame 1 by the clamping member 4. The pins of the transformer circuit board pass through the matching pin top holes 51 on the top surface of the fixture and are inserted into the hollow cavity of the fixture 5. Then, the pins of the transformer circuit board are inserted into the pin clamping holes 54 of the slide plate 52. The slide plate 52 is activated to move laterally in the hollow cavity of the fixture 5, causing the pin clamping holes 54 to press against the pins of the transformer circuit board to ensure electrical connection. Then, the testing equipment in the lower storage box 14 is used. The equipment is electrically connected to the test pins 56 on the bottom surface of the fixture 5 to test the transformer circuit board. If the transformer circuit board passes the test, it is clamped onto the discharge conveyor 3 using the clamping part 4. If it fails, it is clamped onto the unqualified station using the clamping part 4. Thus, the multiple specifications of pin clamping holes 54 and pin top holes 51 opened on the fixture 5 and the slide plate 52 are adapted to the pin testing requirements of different specifications of transformer circuit boards. It is not necessary to disassemble the fixture and replace it with a fixture of appropriate size. This avoids the need to frequently disassemble and replace fixtures and other tools during the production process, thereby improving the transformer testing efficiency and ensuring production efficiency.
[0034] Reference Figure 4Multiple elastic frames 53 are vertically fixed to one end face of the slide plate 52, and the other vertical end face of the multiple elastic frames 53 is fixed to the inner wall of the hollow cavity of the fixture 5. The multiple elastic frames 53 fixed to one end face of the slide plate 52 press against the inner wall of the hollow cavity of the fixture 5. The deformation force generated by the multiple elastic frames 53 pushes the slide plate 52 to slide within the inner wall of the hollow cavity of the fixture 5, which facilitates the later recovery of the slide plate 52 within the inner wall of the hollow cavity of the fixture 5. It is used to press and hold the transformer circuit board pins to maintain stability within the fixture 5. A top block 55 is horizontally fixed to the other end face of the slide plate 52, and the top block 55 is set through one end face of the fixture 5. The top block 55, which is horizontally fixed through the side end face of the slide plate 52, is used to press the slide plate 52 laterally within the hollow cavity of the fixture 5, causing the pin clamping hole 54 to press against the transformer circuit board pins to ensure electrical connection. Pneumatic cylinders 12 are horizontally fixed on one end of the fixture 5 on the frame 1, and the output end of the pneumatic cylinder 12 presses against the top block 55 of the slide plate 52. When the output end of the pneumatic cylinder 12 is activated to press against the top block 55 at the end of the slide plate 52, the slide plate 52 is pushed to move laterally in the hollow cavity of the fixture 5.
[0035] Reference Figure 5 The clamping component 4 includes a first sliding frame 41, which is horizontally fixed to the rear end face of the frame 1. A first slide block 44 is horizontally slidably assembled in the first sliding frame 41, and a second sliding frame 45 is vertically fixed to the top surface of the first slide block 44. The first slide block 44 slides horizontally in the first sliding frame 41, switching the horizontal position of the transformer circuit board being clamped. A second slide block 48 is vertically slidably assembled in the second sliding frame 45, and a pneumatic gripper 49 is vertically fixed to the bottom surface of the second slide block 48. The second slide block 48 moves horizontally in the second sliding frame 45, switching the horizontal position of the transformer circuit board being clamped vertically, using the pneumatic gripper 49 to clamp the transformer circuit board. A first screw 43 is horizontally rotatably connected inside the first sliding frame 41, and the first screw 43 is threaded through and assembled to the bottom surface of the first slide block 44. A first servo motor 42 is horizontally fixed to one end face of the first sliding frame 41, and the output end of the first servo motor 42 is fixed to the side of the first screw 43. The first servo motor 42 is activated, driving the first screw 43 to rotate. The rotation of the first screw 43 drives the first slide block 44 to move horizontally within the first slide frame 41, switching the horizontal position of the clamping and testing transformer circuit board. A second screw 46 is vertically rotatably connected inside the second slide frame 45, and the second screw 46 is threaded through and assembled onto the second slide block 48. A second servo motor 47 is vertically fixed to the top surface of the second slide frame 45, and the output end of the second servo motor 47 is fixed to the end of the second screw 46. Activating the second servo motor 47 drives the second screw 46 to rotate. The rotation of the second screw 46 drives the second slide block 48 to move vertically and horizontally within the second slide frame 45, switching the horizontal position of the clamping and testing transformer circuit board.
[0036] The implementation principle of the transformer comprehensive testing device in this application embodiment is as follows: During use, the transformer circuit board to be tested is transported towards the frame 1 via the feeding conveyor 2 on one side of the frame 1. Then, the transformer circuit board to be tested is clamped and transported onto the fixture of the frame 1 by the clamping member 4. The pins of the transformer circuit board pass through the matching pin top holes 51 on the top surface of the fixture and are inserted into the hollow cavity of the fixture 5. Then, the pins of the transformer circuit board are inserted into the pin clamping holes 54 of the slide plate 52. The output end of the pneumatic cylinder 12 is activated to press against the top block 55 at the end of the slide plate 52, pushing the slide plate 52 to move laterally in the hollow cavity of the fixture 5. The movement of the slide plate 52 in the hollow cavity of the fixture 5 causes the pin clamping holes 54 to press against the pins of the transformer circuit board to ensure electrical connection. Then, the device is activated by the downward movement of the pneumatic cylinder 12 to ensure electrical connection. The testing equipment in the container 14 is electrically connected to the testing pins 56 on the bottom surface of the fixture 5 to test the transformer circuit board. If the transformer circuit board passes the test, it is clamped onto the discharge conveyor 3 using the clamping member 4. If it fails, it is clamped onto the unqualified station using the clamping member 4. The first servo motor 42 is started to drive the first screw 43 to rotate. The rotation of the first screw 43 drives the first slide block 44 to move horizontally in the first slide frame 41, switching the horizontal position of the transformer circuit board to be clamped and tested. The second servo motor 47 is started to drive the second screw 46 to rotate. The rotation of the second screw 46 drives the second slide block 48 to move horizontally in the second slide frame 45, switching the horizontal position of the transformer circuit board to be clamped and tested. The transformer circuit board is clamped using the pneumatic gripper 49.
[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
