Description

Technical Field

[0001] The present invention relates to a transformer performance testing device, in particular to a high-safety high-frequency transformer performance testing device applied in the technical field of transformer testing. Background Art

[0002] A high-frequency transformer is a device used to transfer electrical energy from one circuit to another. The production process of high-frequency transformer semi-finished products requires a series of process steps, such as cutting the core, winding the coil, and insulation treatment. These steps usually require professional equipment and technology to complete. When the semi-finished transformer is supplied to the manufacturer, the transformer performance needs to be tested.

[0003] The specification of Chinese invention patent CN202410149694.9 discloses "A performance test equipment and process for high-frequency transformer semi-finished products". The magnetic element correction unit is used to quickly correct the position of the magnetic elements transported on the conveyor belt, ensuring that the length direction of each magnetic element on the conveyor belt can be kept parallel to the length direction of the conveyor belt, providing convenience for the subsequent rapid contact between the magnetic element and the detection plug. And through the cooperation between the conveying equipment and the detection plug, the performance test of high-frequency transformer semi-finished products is realized in batches, greatly improving the detection efficiency of high-frequency transformer semi-finished products.

[0004] When the transformer is undergoing performance testing on a conveyor belt, the test device has poor contact with the transformer's power terminals, which can easily cause unstable power supply to the transformer and leakage accidents during the test process, affecting the safety of the transformer performance test. At the same time, the power connection unit on the transformer is easily bumped and deformed during the test transmission process, affecting the product quality of the transformer. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the power supply between the test device and the transformer is not stable enough, which may easily cause leakage accidents during the test process and affect the safety of the transformer performance test. At the same time, the power connection unit on the transformer is easily bumped and deformed during the test transmission process, affecting the product quality of the transformer.

[0006] In order to solve the above problems, the present invention provides a high-safety high-frequency transformer performance test device, comprising a test transmission bed, the interior of the test transmission bed is rotatably connected to a conveyor belt, a transformer to be tested is placed on the top of the conveyor belt, a test body is fixedly connected to the top of the test transmission bed, and a test frame is lifted and connected to the middle of the test body, and test modules are fixedly connected to both ends of the test frame;

[0007] The test module includes a fixed rail groove, which is fixedly installed at the bottom of the test frame, and the fixed rail groove is slidably connected to a plurality of power-on unit tubes on the outside, and a power-on rod is sleeved inside the power-on unit tube. Both ends of the top of the transformer to be tested are fixedly connected to power-on poles, and one end of the power-on rod is hinged with a connection piece, which is correspondingly engaged with the root of the power-on pole. A pressure calibration module is fixedly connected to the upper surface of the hinged end of the power-on pole, and a monitoring feeler is fixedly connected to the top of the hinged end of the connection piece, and the monitoring feeler is in contact with the sensing end of the pressure calibration module.

[0008] In the above-mentioned high-safety high-frequency transformer performance testing equipment, the test modules on the test frame are used to test the transmitted transformers to be tested in turn, which effectively improves the test efficiency, and the power-on rod in each power-on unit tube performs a separate power-on test on each power-on post on the transformer to be tested, which effectively improves the accuracy of the performance test. Subsequently, the power-on piece is used to pull up from the root of the power-on post to correct and straighten the power-on post, and the deformation of the power-on post is judged according to the pressure data obtained by the pressure verification module, which effectively improves the product quality of the transformer.

[0009] As a further improvement of the present application, a sensing block is fixedly connected to the middle part of the sensing end of the pressure calibration module, the lower surface of the sensing block is abutted against the top of the monitoring antenna, and a pressure sensor is fixedly connected to the top of the sensing block. The pressure sensor is indirectly subjected to pressure by utilizing the monitoring antenna to abut against the sensing block, thereby effectively improving the protection effect of the pressure sensor.

[0010] As a further improvement of the present application, a marking pen is sleeved inside one end of the pressure calibration module close to the connection piece, the sensing block is in contact with the tail end of the marking pen, and the mutually contacting ends of the sensing block and the marking pen are both arranged in an inclined surface. When the sensing block rises under pressure, the sensing block pushes the tail end of the marking pen through the inclined surface, thereby pushing the tip of the marking pen toward the connection piece, applying a line mark to the surface of the straightened connection pole in the connection piece, so as to facilitate subsequent staff to re-inspect the tested transformer.

[0011] As a further improvement of the present application, the connection piece is bent in a U shape and is made of elastic brass material. A groove is provided in the middle of the connection piece. The tip of the marking pen vertically corresponds to the groove. The U-shaped connection piece effectively improves the power connection effect with the power pole. After the tip of the marking pen marks the power pole, the groove is used to prevent the connection piece from rising and scratching the contact mark.

[0012] As another improvement of the present application, the facing ends of the two fixed rail grooves are telescopically connected in parallel with a lining plate, the open end of the connecting piece is in contact with the lining plate, and the opposite ends of the two fixed rail grooves are telescopically connected in parallel with a wiring push plate, the other end of the power-carrying rod is in contact with the wiring push plate, and the lining plate is used to support the back of the connecting pole, so that the connecting piece can press the power-carrying rod against the surface of the lining plate, effectively improving the correction and straightening effect of the power-carrying rod, and the wiring push plate can facilitate the unified pushing and extension of the power-carrying rod.

[0013] As another improvement supplement of the present application, a connecting groove is opened in the middle of the wiring push plate, and a connecting piece is fixedly connected to the end of the power-carrying rod away from the transformer to be tested. The connecting piece and the connecting groove slide in correspondence with each other. Through the sliding connection between the connecting piece and the connecting groove, the wiring push plate can easily pull and retract the power-carrying rod in a uniform manner.

[0014] As another improvement of the present application, the bottom of the test frame is fixedly connected to a ring rail, the outside of the ring rail is slidably connected to a rotating table, both ends of the rotating table are slidably connected to telescopic plates, the end of the telescopic plate close to the test frame is hinged with a flip clamp, the flip clamp corresponds to the front and back of the transformer to be tested, and a flip cylinder is hinged between the other end of the telescopic plate and the middle part of the flip clamp, the flip clamp clamps the front and back positions of the transformer to be tested, and calibrates the front and back positions of the transformer to be tested. The rotating table rotates on the ring rail to flip the transformer to be tested clamped by the flip clamp upward and take it out, thereby quickly eliminating the transformer to be tested that does not meet the performance requirements and further improving the testing efficiency of the transformer to be tested.

[0015] As another improvement supplement of the present application, a slot is provided on the surface of the flip clamp, and a thickening pad is inserted into the inside of the slot. The thickening pad increases the overall thickness of the flip clamp, thereby facilitating the flip clamp to clamp transformers to be tested with different front and rear lengths.

[0016] As another improvement supplement to the present application, the thickening pad is provided with various specifications according to the thickness. The thickening pad is made of rubber material. The thickening pads of various specifications are suitable for different transformers to be tested. The thickening pad made of rubber material has good deformation ability, which effectively improves the clamping stability of the flip clamp on the transformer to be tested.

[0017] In summary, the present invention transmits the transformer to be tested on a conveyor belt, and then uses the test module on the test frame to test the transmitted transformer to be tested in turn, thereby effectively improving the test efficiency. When the transformer to be tested is transmitted to the bottom of the test frame, the power-on rod in each power-on unit tube performs a separate power-on test on each power-on post on the transformer to be tested, thereby effectively improving the accuracy of the performance test. The power-on post is clamped by a connection piece, thereby effectively improving the power-on stability of the transformer to be tested, thereby effectively improving the safety effect of the test equipment. Subsequently, the connection piece is used to pull up from the root of the power-on post to correct and straighten the power-on post, and the deformation of the power-on post is judged according to the pressure data obtained by the pressure verification module, thereby effectively improving the product quality of the transformer.

[0032] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-2 A high-safety high-frequency transformer performance test device is shown, comprising a test transmission bed 1, a conveyor belt 101 is rotatably connected inside the test transmission bed 1, a transformer 2 to be tested is placed on the top of the conveyor belt 101, a test body 102 is fixedly connected to the top of the test transmission bed 1, a test frame 103 is lifted and connected to the middle of the test body 102, and test modules 3 are fixedly connected to both ends of the test frame 103;

[0035] When performing a performance test on a transformer, the transformer 2 to be tested is placed on the conveyor belt 101 on the test transmission bed 1 for transportation, and the test module 3 sequentially powers on the transformer 2 to test, thereby effectively improving the performance test efficiency of the transformer 2 to be tested.

[0036] Figure 2-5 As shown, the test module 3 includes a fixed rail groove 301, which is fixedly installed at the bottom of the test frame 103, and a plurality of power-on unit cylinders 302 are slidably connected to the outside of the fixed rail groove 301, and a power-on rod 303 is sleeved inside the power-on unit cylinder 302. Both ends of the top of the transformer 2 to be tested are fixedly connected to the power-on posts 201, and one end of the power-on rod 303 is hinged with a connection piece 304, which is corresponding to the root of the power-on post 201;

[0037] After the transformer 2 to be tested is at the bottom of the test frame 103, the power-on rod 303 in each power-on unit tube 302 performs a separate power-on test on each power-on post 201 on the transformer 2 to be tested, thereby effectively improving the accuracy of the performance test, and utilizing the connection piece 304 to clamp the power-on post 201 to effectively improve the power-on stability of the transformer 2 to be tested, thereby effectively improving the safety effect of the test equipment, and subsequently utilizing the connection piece 304 to pull up from the root of the power-on post 201 to correct and straighten the power-on post 201, and based on the pressure data obtained by the pressure verification module 305, determine the deformation of the power-on post 201, thereby effectively improving the product quality of the transformer.

[0038] Figure 6-8 It is shown that a pressure calibration module 305 is fixedly connected to the upper surface of the hinged end of the power pole 201, a monitoring feeler 306 is fixedly connected to the top of the hinged end of the connection piece 304, the monitoring feeler 306 is in contact with the sensing end of the pressure calibration module 305, the connection piece 304 is bent in a U shape, and the connection piece 304 is made of elastic brass material. The U-shaped connection piece 304 effectively improves the power connection effect with the power pole 201, and a sensing block 307 is fixedly connected to the middle of the sensing end of the pressure calibration module 305, the lower surface of the sensing block 307 is in contact with the top of the monitoring feeler 306, and the top of the sensing block 307 is fixedly connected with a pressure sensor 308. The monitoring feeler 306 is in contact with the sensing block 307, so that the pressure sensor 308 is indirectly subjected to pressure, which effectively improves the protection effect of the pressure sensor 308.

[0039] When the connection piece 304 is pulled upward from the root of the power pole 201, if the power pole 201 is in a bent state at this time, the rising connection piece 304 corrects and straightens the bent power pole 201. During the straightening process, the connection piece 304 is subjected to the reaction pressure and flips downward, so that the monitoring antenna 306 at the hinged end of the connection piece 304 upwardly resists the pressure verification module 305, specifically, upward pressure is applied to the sensing block 307, and pressure detection is performed using the pressure sensor 308, so as to judge the difficulty of straightening the power pole 201 from bending to vertical through the obtained pressure data, and judge whether the over-bent power pole 201 is worth continuing to straighten, and avoid damage to the transformer caused by straightening the over-bent power pole 201.

[0040] Figure 4-5As shown, a marking pen 309 is sleeved inside one end of the pressure calibration module 305 close to the connection piece 304, the sensing block 307 is in contact with the tail end of the marking pen 309, and the mutually contacting ends of the sensing block 307 and the marking pen 309 are both arranged in an inclined surface. When the sensing block 307 is pressurized and rises, the sensing block 307 pushes the tail end of the marking pen 309 through the inclined surface, thereby pushing the tip of the marking pen 309 to extend toward the connection piece 304, and applying a line mark to the surface of the straightened connection column 201 in the connection piece 304, so as to facilitate the subsequent staff to re-inspect the tested transformer. A groove 310 is provided in the middle of the connection piece 304, and the tip of the marking pen 309 is vertically corresponding to the groove 310. After the tip of the marking pen 309 marks the connection column 201, the groove 310 is used to prevent the connection piece 304 from rising and scratching the contact mark.

[0041] When the connection piece 304 straightens the connection post 201, the sensing block 307 rises due to the pressure from the monitoring antenna 306. The sensing block 307 pushes the tail end of the marking pen 309 through the inclined surface, thereby pushing the tip of the marking pen 309 toward the connection piece 304, so that the marking pen 309 draws a marking line on the surface of the connection post 201. The staff can judge from the marking line that the connection post 201 has been corrected during the test, which is convenient for the staff to re-inspect the connection post 201, thereby effectively improving the product quality of the transformer.

[0042] The second implementation method:

[0043] Compared with the first embodiment, the ring rail 4 and the flip clamp 403 are mainly added. The specific added structure is as follows. The rest of the structure is the same as the first embodiment.

[0044] Figure 9-11 As shown, the bottom of the test frame 103 is fixedly connected to a ring rail 4, the outside of the ring rail 4 is slidably connected to a rotating table 401, both ends of the rotating table 401 are slidably connected to telescopic plates 402, one end of the telescopic plate 402 close to the test frame 103 is hinged to a flip clamp 403, the flip clamp 403 corresponds to the front and back sides of the transformer 2 to be tested, and a flip cylinder 404 is hinged between the other end of the telescopic plate 402 and the middle of the flip clamp 403;

[0045] After the transformer 2 to be tested moves to the bottom of the test frame 103, the test frame 103 descends to the top of the transformer 2 to be tested, and the flip cylinder 404 pushes the flip clamp 403 to flip downward. The flip clamp 403 clamps the front and rear positions of the transformer 2 to be tested, and pushes the transformer 2 to be tested directly below the test frame 103. The telescopic plate 402 slides on the rotating table 401 to shrink the spacing between the two flip clamps 403, thereby adapting to the transformer 2 to be tested with different front and rear widths. Compared with the existing test equipment that only performs left and right calibration on the transformer 2 to be tested, the position calibration accuracy of the transformer 2 to be tested is effectively improved, and the test module 3 is effectively improved to accurately connect the transformer 2 to be tested, thereby effectively avoiding safety accidents caused by wiring misalignment, and effectively improving the safety of transformer testing. When the transformer 2 to be tested does not meet the performance test requirements, the rotating table 401 rotates on the ring track 4 to flip the transformer 2 to be tested clamped by the flip clamp 403 upward and take it out, thereby quickly eliminating the transformer 2 to be tested that does not meet the performance requirements, and further improving the test efficiency of the transformer 2 to be tested.

[0046] Fig.12 As shown, a slot 405 is provided on the surface of the flip clamp 403, and a thickening pad 406 is inserted inside the slot 405. The thickening pad 406 increases the overall thickness of the flip clamp 403, so that it is convenient for the flip clamp 403 to clamp the transformer 2 to be tested with different front and rear lengths. The thickening pad 406 has various specifications according to the thickness. The thickening pad 406 is made of rubber material. The thickening pad 406 of various specifications is suitable for different transformers to be tested. The thickening pad 406 made of rubber material has good deformation ability, which effectively improves the clamping stability of the flip clamp on the transformer to be tested.

[0047] According to the specification type of the transformer 2 to be tested, a thickening pad 406 of suitable thickness is selected, and the thickening pad 406 is used to change the clamping method of the flip clamp 403 on the transformer to be tested 2 to adapt to different transformers to be tested 2. When the flip clamp 403 flips downward to contact the transformer 2 to be tested, the elastic force of the thickening pad 406 is used for clamping and buffering, thereby effectively improving the clamping stability of the flip clamp 403 on the transformer to be tested 2.

[0048] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
