Description

Technical Field

[0001] This invention relates to the technical field of high-frequency transformer assembly and testing, specifically to a high-frequency transformer assembly and testing production line. Background Technology

[0002] A high-frequency transformer is an electronic component based on the principle of electromagnetic induction. It uses high-frequency alternating current to create a rapidly changing magnetic field in the magnetic core, which in turn induces a voltage in the secondary coil. High-frequency transformers can not only realize voltage and current transformation and energy transmission, but also ensure the safe operation of the circuit through electrical isolation.

[0003] During the production and assembly process of high-frequency transformers, in order to ensure that they meet the design performance requirements and are safe to use, a series of inspection and testing processes, such as withstand voltage testing, inductance measurement, and resistance measurement, are required using professional testing equipment.

[0004] A search of the invention patent with authorization announcement number CN116559610B reveals a high-frequency transformer withstand voltage testing device. Through a specially designed placement platform assembly structure, it can adapt to the size of the high-frequency transformer, ensuring its stability during testing. A cylinder is fixedly installed on the top surface of the insulating plate, and slide rails are fixedly connected to both sides of the top surface of the insulating plate. A test plate is sleeved on the surface of the slide rails, and test terminals are embedded in the surface of the test plate. The test terminals are connected to an external withstand voltage testing machine, effectively completing the withstand voltage test of the high-frequency transformer.

[0005] Based on the aforementioned patents and existing solutions, as well as practical production and processing, the current high-frequency transformer assembly and testing production line still has some problems, such as:

[0006] In the aforementioned patent, during the testing of a high-frequency transformer, after the high-frequency transformer is placed, the cylinder is activated to drive the test board to slide, so that the test terminals are connected to the pins of the high-frequency transformer. This testing method of directly connecting to the pins of the high-frequency transformer is the same as the existing high-frequency transformer testing method. Both methods directly connect the test equipment's wiring terminals to the pins of the high-frequency transformer. However, direct connection may result in inaccurate connection due to angular deviation. Applying pressure may cause deformation and bending of the high-frequency transformer pins, affecting the test results and directly damaging the high-frequency transformer.

[0007] Therefore, we propose a high-frequency transformer assembly and testing production line to address the problems mentioned above. Summary of the Invention

[0008] The purpose of this invention is to provide a high-frequency transformer assembly and testing production line to solve the problems mentioned in the background art, such as the inability to accurately connect the terminals of the testing equipment to the pins of the high-frequency transformer due to angular deviation, and the deformation and bending of the high-frequency transformer pins after applying pressure, which affect the test results.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a high-frequency transformer assembly and testing production line, comprising:

[0010] The support frame has a servo motor assembly fixedly connected therein, which drives a rotating disk that can rotate intermittently. The support frame has a test mechanism for high-frequency transformer inspection.

[0011] Also includes:

[0012] A feeding conveyor belt is installed on the left side of the support frame, and an unloading conveyor belt is installed on the right side of the support frame. The feeding conveyor belt and the unloading conveyor belt are respectively equipped with a feeding and unloading mechanism for automatically feeding high-frequency transformers and an automatic picking and placing feeding and unloading mechanism.

[0013] The housing is arranged in a ring array on the rotating disk and is used for the mounting of the high-frequency transformer. The housing is provided with a communication mechanism for protective indirect connection between the pins of the high-frequency transformer and the testing mechanism.

[0014] Preferably, the testing mechanism includes a first cylinder fixed to a bracket in the support frame and a test terminal fixed to the output end of the first cylinder. The test terminal forms a lifting structure on the bracket in the support frame by being driven by the first cylinder. The test terminal is electrically connected to the test chassis placed on the bracket in the support frame via a data cable.

[0015] Preferably, the feeding mechanism in the feeding conveyor belt includes a "U"-shaped frame that is movably connected to the high-frequency transformer and a blocking frame for positioning the high-frequency transformer. The "U"-shaped frame is driven by a second cylinder fixed to the connecting frame in the feeding conveyor belt to form a lifting structure on the feeding conveyor belt. The blocking frame is fixed to the end of the feeding conveyor belt.

[0016] The placement of the feeding mechanism in the feeding conveyor belt is the same as that in the unloading conveyor belt.

[0017] Preferably, the front and rear sides of the blocking frame are provided with baffles for limiting the high-frequency transformer during transmission. The baffles form a flipping structure on the blocking frame, and a first torsion spring is installed at the flipping connection between the two. The baffles are connected to the "U"-shaped frame by pushing.

[0018] Preferably, the connecting mechanism is arranged at equal intervals on the housing component. The connecting mechanism includes an outer shell fixed to a transverse seat in the housing component, two clamping plates symmetrically arranged about the vertical central axis of the outer shell, and a linkage frame for synchronous driving of the two clamping plates. An integrated connecting column is provided at the center of the upper end of the outer shell, and the connecting column is connected to the test terminal by plugging. The clamping plates form a sliding structure inside the outer shell, and a reset spring is installed at the sliding connection between the two. The sliding directions of the two clamping plates in the outer shell are arranged in opposite directions.

[0019] Among them, the two clamping plates in the outer shell, together with conductive metal sheets, clamp and fix the pins of the high-frequency transformer, and the conductive metal sheets in the clamping plates are electrically connected to the conductive metal post in the connecting post through wires;

[0020] In the linkage frame, the plate body portion forms a sliding structure within the plate cavity of the clamping plate. Both plate bodies in the linkage frame are provided with inclined groove portions, and the inclined groove portions on the two plate bodies in the linkage frame are arranged in opposite directions. The inclined groove portions are slidably connected to the pin in the clamping plate.

[0021] Preferably, the multiple connecting mechanisms in the housing are synchronously driven by the adjusting frame. The adjusting frame forms a sliding structure on the transverse seat in the housing. The frame wall of the adjusting frame is fixedly connected to the sleeve part in the linkage frame. The two form a synchronous movement structure. A first spring is installed at the sliding connection between the sleeve part in the linkage frame and the connecting column.

[0022] The adjusting frame is movably inserted into the annular cavity of the annular cover fixed to the bracket in the support frame. Both the inner and outer annular cavity walls of the annular cover are provided with annular groove groups, and the annular groove groups are slidably connected to the pins fixed to the adjusting frame.

[0023] Preferably, the annular groove assembly includes a lower annular groove located behind the annular cover, an upper annular groove located in front of the annular cover, and an inclined connecting groove for communication between the lower annular groove and the upper annular groove. The misalignment distance between the lower annular groove and the upper annular groove is equal to the maximum sliding distance of the adjusting frame.

[0024] Preferably, each of the two longitudinal seats of the housing is connected to a fixed claw by flipping, and a second torsion spring is installed at the flipping connection between the two. The pushing section of the fixed claw is connected to the upper side of the high-frequency transformer by pushing, and the clamping section of the fixed claw is connected to the side of the high-frequency transformer by pressing. The flipping directions of the two fixed claws in the housing are arranged in opposite directions, so that the high-frequency transformer stuck in the housing is automatically clamped and locked by the two fixed claws.

[0025] Preferably, an unlocking block is telescopically slidably connected to the middle position of the transverse seat in the housing component, and a second spring is installed at the sliding connection between the two. The unlocking block is connected to the push rod assembly fixed to the bracket in the support frame by a pressing manner.

[0026] The two longitudinal blocks in the unlocking block are each provided with a locking block that can slide within the housing. The two locking blocks in the unlocking block slide in opposite directions, and a third spring is installed between the two locking blocks. The locking blocks are connected to the arc-shaped end of the pushing section claw in the fixed claw by a snap-fit ​​method.

[0027] The lower end of the longitudinal block in the unlocking block is provided with an inclined sidewall, and the inclined sidewall of the longitudinal block in the unlocking block is slidably attached to and connected with the inclined groove wall provided in the through groove of the locking block.

[0028] Compared with the prior art, the beneficial effects of the present invention are: the high-frequency transformer assembly and testing production line allows the high-frequency transformer pins to be easily and unobstructed when inserted, without the phenomenon of deformation or bending caused by pin angle deviation. Furthermore, the protective indirect connection avoids damage to the pins during testing, ensuring the accuracy of the test results. In addition, the automatic feeding or automatic pick-up and drop-off operation improves the efficiency of production testing.

[0029] 1. After the high-frequency transformer plug is placed inside the housing, each pin of the high-frequency transformer is inserted into each connecting mechanism on the housing in a corresponding manner. A large gap is reserved between the two clamping plates in the connecting mechanism to ensure that the pins of the high-frequency transformer can be easily and unobstructedly inserted. The large gap setting prevents the pins of the high-frequency transformer from being obstructed or deformed and bent due to pin angle deviation when inserted, thus providing good protection for the pins of the high-frequency transformer.

[0030] Furthermore, by using two opposing sliding clamping plates in the connecting mechanism, the pins of the high-frequency transformer are clamped and fixed, so that the conductive metal sheet in the clamping plate is in contact with the pins of the high-frequency transformer to form an electrical connection. The conductive metal sheet in the clamping plate is electrically connected to the conductive metal post in the connecting post through a wire. After the test terminal is connected to the connecting post, the high-frequency transformer can be tested. The clamping and fixing method can effectively protect the pins of the high-frequency transformer. In addition, the protective indirect connection can prevent the pins from being damaged during testing, ensuring the accuracy of the test results and reducing the scrap rate of the high-frequency transformer during testing.

[0031] Furthermore, when the pin slides from the upper half of the annular groove to the lower half of the annular groove, it drives the adjusting frame to move downward. Through the sliding fit between the pin and the inclined groove in the clamping plate, the two clamping plates slide in opposite directions, automatically clamping and fixing the high-frequency transformer pin to form an electrical connection. When the pin slides back from the lower half of the annular groove to the upper half of the annular groove, it drives the adjusting frame to move upward. Through the sliding fit between the pin and the inclined groove in the clamping plate, and through the elastic deformation of the reset spring, the two clamping plates slide in opposite directions, automatically releasing the clamping and fixing of the high-frequency transformer pin and disconnecting the electrical connection, ensuring convenient operation.

[0032] 2. When the feeding conveyor belt delivers the high-frequency transformer, the U-shaped frame is driven to move upward, automatically engaging and picking up the high-frequency transformer. This causes the high-frequency transformer to move upward synchronously and dock with the housing, thus achieving automatic feeding. When the unloading conveyor belt picks up and places the high-frequency transformer, the U-shaped frame is driven to move downward, causing the high-frequency transformer to move downward synchronously. This allows the high-frequency transformer to fall onto the unloading conveyor belt and automatically disengage, thus achieving automatic picking and placing. Through the automation settings, the continuity of testing work is ensured, and the efficiency of production testing is improved.

[0033] 3. When the high-frequency transformer is docked with the housing, the upper part of the high-frequency transformer pushes the arc-shaped end of the pressing section of the fixing claw, causing the fixing claw to flip inside the housing. After the two fixing claws flip and close in opposite directions, they automatically clamp and lock the high-frequency transformer after installation, ensuring the stability of the high-frequency transformer after installation. This allows the high-frequency transformer to be tested in a stable and locked state, ensuring the accuracy of the test results. Attached Figure Description

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Example 1:

[0054] This invention provides a technical solution: a high-frequency transformer assembly and testing production line. This addresses the problem that during production testing, the terminals of the testing equipment directly connect to the pins of the high-frequency transformer, failing to protect the pins and causing inaccurate connection due to angular deviations. Furthermore, applying pressure can lead to deformation and bending of the transformer pins, affecting testing results. The feeding conveyor belt 5 automatically feeds the high-frequency transformer into the housing 8 via its feeding mechanism 7. The high-frequency transformer is then secured within the housing 8, and its pins are inserted into the corresponding connecting mechanism 9. The housing 8, along with the filled high-frequency transformer, rotates intermittently with the rotating disc 3. During this rotation... The sliding engagement between the ring groove assembly 25 and the pin 2201 causes the adjustment frame 22 to operate the connecting mechanism 9, clamping and fixing the high-frequency transformer pins to form an electrical connection. The connecting mechanism 9 is used for protective indirect docking between the high-frequency transformer pins and the testing mechanism 4. Then, the housing 8, along with the filled high-frequency transformer, rotates to directly below the testing mechanism 4. Through the docking of the testing mechanism 4 and the connecting mechanism 9, the high-frequency transformer is tested. Finally, the housing 8, along with the tested high-frequency transformer, intermittently rotates to directly above the unloading conveyor belt 6. The feeding and picking mechanism 7 on the unloading conveyor belt 6 automatically picks up and places the high-frequency transformer onto the unloading conveyor belt 6 for outward transport.

[0055] This technical solution: Please refer to Figures 1-13 A high-frequency transformer assembly and testing production line includes a support frame 1. After the support frame 1 is installed, it is fixedly mounted on the cabinet of the assembly and testing production line by bolts. The upper end of the support frame 1 is driven by a servo motor assembly 2 fixed inside it to drive a rotating disk 3 that can rotate intermittently. A testing mechanism 4 for high-frequency transformer inspection is provided on the bracket of the support frame 1.

[0056] It also includes a feeding conveyor belt 5 and a housing 8. The feeding conveyor belt 5 is located to the left of the support frame 1, and the unloading conveyor belt 6 is located to the right of the support frame 1. The feeding conveyor belt 5 and the unloading conveyor belt 6 are respectively positioned horizontally at the lower left and lower right of the transfer disc 3. The feeding conveyor belt 5 and the unloading conveyor belt 6 are respectively equipped with a feeding and unloading mechanism 7 for automatically feeding the high-frequency transformer and an automatic pick-up and drop-off feeding and unloading mechanism 7. The housing 8 is arranged in a ring array on the transfer disc 3 and is used for the locking and placement of the high-frequency transformer. The housing 8 is equipped with a communication mechanism 9 for protective indirect connection between the high-frequency transformer pins and the testing mechanism 4.

[0057] Specifically, in this technical solution, the high-frequency transformer is automatically fed into the housing component 8 via the feeding mechanism 7 on the feeding conveyor belt 5. Figure 1 , Figure 4 and Figure 6 As shown, the feeding conveyor belt 5 is located to the left of the support frame 1. The feeding conveyor belt 5 is composed of two parts: a frame and a conveyor belt. The front and rear sides of the frame are vertically fixed with limit guide plates by bolts, and the right end of the frame is fixed to the left side wall of the support frame 1 by bolts. Since the front and rear limit guide plates of the feeding conveyor belt 5 are combined with the frame to form a guide cavity that is compatible with the high-frequency transformer, the high-frequency transformer is movably locked in the guide cavity formed by the limit guide plates and the frame of the feeding conveyor belt 5. The lower part of the high-frequency transformer is attached to the conveyor belt of the feeding conveyor belt 5. When the feeding conveyor belt 5 is started, the high-frequency transformer is driven by the conveyor belt to slide in the guide cavity formed by the limit guide plates and the frame, so that the high-frequency transformer is conveyed to the transfer disc 3.

[0058] Since the feeding mechanism 7 includes a "U"-shaped frame 13 and a blocking frame 14, the "U"-shaped frame 13 is divided into a horizontal frame and two longitudinal frames located on the front and rear sides of the horizontal frame. The blocking frame 14 is used for positioning the high-frequency transformer. After the blocking frame 14 is installed in the feeding conveyor belt 5, it is vertically fixed to the right end of the frame of the feeding conveyor belt 5 by bolts. Since the upper end of the longitudinal frame of the "U"-shaped frame 13 is flush with the conveyor belt of the feeding conveyor belt 5 in the initial state, it does not affect the conveying of the high-frequency transformer. When the high-frequency transformer is conveyed to the changing plate 3 on the feeding conveyor belt 5, the blocking frame 14 blocks the high-frequency transformer in the conveying process, so that the high-frequency transformer is positioned at the "U"-shaped frame 13.

[0059] Because the feeding conveyor belt 5 is equipped with a feeding and taking mechanism 7 for automatic feeding of high frequency transformers, and the lower side of the frame of the feeding conveyor belt 5 is equipped with an integrated connecting frame, and because the "U" shaped frame 13 in the feeding conveyor belt 5 is vertically positioned on the feeding conveyor belt 5 after being installed, and the front and rear longitudinal frames of the "U" shaped frame 13 are respectively movably locked on the front and rear sides of the frame of the feeding conveyor belt 5, so that the "U" shaped frame 13 is positioned in a movable state on the feeding conveyor belt 5, and because the second cylinder 15 in the feeding conveyor belt 5 is fixedly installed on the connecting frame of the feeding conveyor belt 5 by bolts, and the output end is inserted into and fixedly connected to the transverse frame of the "U" shaped frame 13 by bolts, the second cylinder 15 is started to extend and operate, so that the "U" shaped frame 13 is driven to rise on the feeding conveyor belt 5;

[0060] Since the upper end of the longitudinal frame of the "U"-shaped frame 13 has a groove that is compatible with the high-frequency transformer, when the "U"-shaped frame 13 moves upward and docks with the high-frequency transformer, the front and rear sides of the lower end of the high-frequency transformer respectively move and engage in the grooves of the front and rear longitudinal frames of the "U"-shaped frame 13, so that the high-frequency transformer and the "U"-shaped frame 13 are moved and engaged together. When the "U"-shaped frame 13 continues to move upward, it drives the high-frequency transformer on it to move upward synchronously.

[0061] Since the four empty slots on the front, back, left, and right sides of the rotating disc 3 are all equipped with housing components 8, the feeding mechanism 7 in the feeding conveyor belt 5 is positioned directly below the empty slot on the left side of the rotating disc 3, that is, it is on the same vertical central axis as the housing component 8 in the empty slot on the left side of the rotating disc 3. Since the housing component 8 is arranged in a "U" shape, it is divided into a horizontal seat and two vertical seats. The vertical seats in the housing component 8 have grooves that are compatible with the high-frequency transformer, and the size of the grooves is the same as the size of the grooves on the vertical frame in the "U" shaped frame 13. After the "U" shaped frame 13 drives the high-frequency transformer to move upward continuously, the upper end of the vertical frame in the "U" shaped frame 13 is connected and attached to the lower end of the housing component 8. The housing component 8 is connected to the high-frequency transformer, so that the front and back sides of the high-frequency transformer are respectively inserted into the grooves of the front and back vertical seats in the housing component 8, completing the automatic feeding operation of the high-frequency transformer and completing the insertion and placement of the high-frequency transformer in the housing component 8.

[0062] In summary, after the automatic feeding operation of the high-frequency transformer is completed, the second cylinder 15 of the feeding conveyor belt 5 is started to retract and operate, driving the "U"-shaped frame 13 to descend and lose contact with the high-frequency transformer, and return to the initial state, so as to accurately feed the next high-frequency transformer automatically.

[0063] Meanwhile, in the above technical solutions, according to Figure 4 , Figure 6 and Figure 7As shown, baffles 16 for limiting the transmission of high-frequency transformers are provided on both the front and rear sides of the blocking frame 14. Since the front and rear sides of the blocking frame 14 are provided with integrated shaft columns, the ends of which are sleeved and fixed with bolts to a ring sleeve, and since the lower end of the baffle 16 is movably sleeved on the shaft column of the blocking frame 14 after installation, the baffle 16 forms a rotating structure on the shaft column of the blocking frame 14. By limiting the movement of the ring sleeve on the shaft column of the blocking frame 14, the baffle 16 is positioned in a movable state on the blocking frame 14.

[0064] Since the side wall of the baffle 16 is flush with the side wall of the limiting guide plate in the feeding conveyor belt 5, and since a first torsion spring 17 is installed at the flip connection between the baffle 16 and the blocking frame 14, the first torsion spring 17 is symmetrically arranged about the horizontal central axis of the blocking frame 14. The two first torsion springs 17 are respectively applied to the two baffles 16. After the first torsion spring 17 is installed, it is movably sleeved on the central column of the blocking frame 14. One end of it is clamped on the baffle 16, and the other end of it is clamped on the blocking frame 14. When the baffle 16 is flipped and closed, it is in the initial state. Its upper end overlaps and adheres to the limiting guide plate in the feeding conveyor belt 5. It is used to fill the gap after the "U" shaped frame 13 slides down, that is, to limit the high frequency transformer in the conveying process, so that the high frequency transformer can be accurately conveyed to the "U" shaped frame 13.

[0065] In summary, when the U-shaped frame 13 is driven to move upward, the U-shaped frame 13 and the baffle 16 are connected by pushing, causing the baffle 16 to be pushed onto the blocking frame 14 and unfold. This causes the first torsion spring 17 to be compressed and undergo elastic deformation. After the baffle 16 unfolds, it does not affect the upward sliding of the U-shaped frame 13. When the U-shaped frame 13 is driven to move downward, the U-shaped frame 13 loses its pushing effect on the baffle 16. The elastic deformation of the first torsion spring 17 is used to reset the baffle 16, causing the baffle 16 to flip and close on the blocking frame 14 to return to its initial state and fill the gap.

[0066] Specifically, in this technical solution, the rotating disk 3 drives the housing component 8 to perform intermittent rotation operation, according to... Figure 1 and Figure 2As shown, the lower side wall of the rotating disk 3 is provided with a shaft tube section co-centered therewith, and a bearing is fixedly snapped onto the shaft tube section. After the rotating disk 3 is placed, it is set horizontally on the support frame 1. The shaft tube section, along with the bearing, is inserted into the upper side wall of the support frame 1. Since the support frame 1 has a hollow structure with a frame, the servo motor assembly 2 is fixedly installed on the upper side frame cavity wall of the frame in the support frame 1 by bolts. Since the core of the shaft tube section of the rotating disk 3 is provided with an integrated shaft column, the shaft column is fixedly sleeved on the output end of the servo motor assembly 2 after the rotating disk 3 is placed. When the servo motor assembly 2 is started, it operates and the rotating disk 3 is operated to rotate intermittently. The rotation angle of the rotating disk 3 during intermittent rotation is ninety degrees each time.

[0067] Since the rotating disk 3 has four empty slots arranged in a circular array with the center of the rotating disk 3 as the center, and the four empty slots are respectively located in the center of the front, back, left and right sides of the rotating disk 3, and since there are four housing parts 8 arranged in a circular array on the rotating disk 3, each housing part 8 corresponds to each empty slot in the rotating disk 3. After the housing parts 8 are installed, they are inserted vertically through the empty slots in the rotating disk 3 and extend downwards. They are fixed to the rotating disk 3 by bolts. When the rotating disk 3 rotates intermittently, the positions of the four housing parts 8 are rotated once with each rotation.

[0068] Specifically, in this technical solution, after the high-frequency transformer clip is placed inside the housing 8, the connecting mechanism 9 clamps and fixes the high-frequency transformer pins to form an electrical connection. Figure 3 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, the housing 8 is provided with a connecting mechanism 9 for protective indirect connection between the high-frequency transformer pins and the test mechanism 4, and the electrical connection between the high-frequency transformer pins and the test mechanism 4 is made through the connecting mechanism 9. Since the connecting mechanisms 9 are arranged at equal intervals on the transverse seat of the housing 8, each connecting mechanism 9 corresponds to each pin in the high-frequency transformer. Since the connecting mechanism 9 includes a housing 18 with its lower end open, two clamping plates 19 symmetrically arranged about the vertical central axis of the housing 18, and a linkage frame 20 for synchronous driving of the two clamping plates 19, after the high-frequency transformer is inserted into the housing 8, the pins of the high-frequency transformer are inserted into the cavity of the housing 18 through the lower opening of the housing 18, and the pins of the high-frequency transformer are inserted into the gap between the two clamping plates 19, thus completing the corresponding insertion between the high-frequency transformer pins and the connecting mechanism 9.

[0069] Since the rear side wall of the support frame 1 is provided with an integrated bracket structure, the annular cover 24 is fixedly connected to the bracket in the support frame 1 by bolts after it is installed, corresponding to the top of the rotating disk 3 and set in a parallel state with the rotating disk 3. Furthermore, since the left, right and rear sides of the annular cover 24 are provided with slots, the left slot, rear slot and right slot are respectively provided with corresponding slots in the rotating disk 3, that is, the annular cover 24 will not obstruct the housing 8 in the rotating disk 3.

[0070] Since the central position of the transverse seat in the housing 8 is provided with an integrated protrusion, the adjusting frame 22 is movably sleeved on the protrusion of the transverse seat in the housing 8 after it is installed. Since the adjusting frame 22 is movably inserted into the annular cavity of the annular cover 24, the center of the annular cover 24 coincides with the rotation center of the rotating disk 3. When the rotating disk 3 drives the housing 8 to rotate intermittently, the adjusting frame 22 can slide in the annular cavity of the annular cover 24.

[0071] Since the two side walls of the adjusting frame 22 extend outward horizontally, the pin 2201 is threadedly fixed in the middle of the outwardly extending frame wall of the adjusting frame 22 in a vertical state, and is symmetrical about the central axis of the adjusting frame 22. Since the inner and outer annular cavity walls of the annular cover 24 are provided with annular groove groups 25, the center of the annular groove group 25 coincides with the center of the annular cover 24. The annular groove group 25 on the inner annular cavity wall and the annular groove group 25 on the outer annular cavity wall of the annular cover 24 correspond to two pins 2201 respectively. Since the pin 2201 is movably inserted into the annular groove group 25 after installation, when the adjusting frame 22 slides in the annular cavity of the annular cover 24, the pin 2201 slides along the annular groove group 25.

[0072] Since the annular groove assembly 25 includes a lower half-annular groove 2501 located behind the annular cover 24, an upper half-annular groove 2502 located in front of the annular cover 24, and an inclined connecting groove 2503 for communication between the lower half-annular groove 2501 and the upper half-annular groove 2502, and inclined connecting grooves 2503 are provided at both the left and right connecting points of the lower half-annular groove 2501 and the upper half-annular groove 2502, and since the upper half-annular groove 2502 and the lower half-annular groove 2501 are staggered vertically... In position setting, the misalignment distance between the lower half annular groove 2501 and the upper half annular groove 2502 is equal to the maximum sliding distance of the adjusting frame 22. When the pin 2201 slides along the annular groove group 25, the middle pin 2201 slides from the upper half annular groove 2502 into the lower half annular groove 2501 through the inclined connecting groove 2503. The position of the pin 2201 drops, causing the adjusting frame 22 to slide downward on the transverse seat in the housing 8.

[0073] Since the linkage frame 20 is composed of a sleeve part and two plate parts symmetrically arranged about the central axis of the sleeve part, the frame wall extending outward in the adjusting frame 22 is inserted through the sleeve part in the linkage frame 20 and fixed together with bolts. Multiple connecting mechanisms 9 in the housing 8 are synchronously driven by the adjusting frame 22. That is, the adjusting frame 22 and multiple linkage frames 20 are fixed together, and it and multiple linkage frames 20 form a synchronous movement structure. Since the sleeve part of the linkage frame 20 is movably sleeved outside the connecting column 1801 after the linkage frame 20 is installed, after the adjusting frame 22 is driven to move down, the sleeve part in the linkage frame 20 slides down on the connecting column 1801.

[0074] Since a first spring 23 is installed at the sliding connection between the sleeve part of the linkage frame 20 and the connecting column 1801, the first spring 23 is movably sleeved outside the connecting column 1801 after being installed. One end of the first spring 23 presses against the sleeve part of the linkage frame 20, and the other end presses against the upper shell wall of the outer shell 18. After the sleeve part of the linkage frame 20 slides down on the connecting column 1801, the first spring 23 is compressed and undergoes elastic deformation.

[0075] Because the clamping plate 19 is hollow and has a through-hole, and because after the linkage frame 20 is installed, two of its plate parts can move through the upper side wall of the outer shell 18 and extend into the seat cavity of the outer shell 18, and two of its plate parts are respectively moved and inserted into the plate cavities of the two clamping plates 19, the linkage frame 20 is positioned on the outer shell 18 in a movable state. After the sleeve part of the linkage frame 20 slides down on the connecting column 1801, the plate parts of the linkage frame 20 slide down synchronously in the plate cavities of the clamping plate 19.

[0076] Since the two plates in the linkage frame 20 are provided with through grooves 2001, and the upper and lower ends of the plates are also provided with grooves 2001, and the grooves 2001 on the two plates in the linkage frame 20 are arranged in opposite directions, and since the upper and lower ends of the clamping plate 19 are connected with pins by bolts, and the two pins correspond to the two grooves 2001 respectively, after the linkage frame 20 and the clamping plate 19 are connected, the pins in the clamping plate 19 move through the grooves 2001. When the plates in the linkage frame 20 slide down in the plate cavity of the clamping plate 19, the pins in the clamping plate 19 slide along the grooves 2001. Through the sliding cooperation between the pins in the clamping plate 19 and the grooves 2001, the two clamping plates 19 are driven to move in opposite directions.

[0077] After the outer shell 18 is installed, it is locked and fixed to the transverse seat in the housing 8 by bolts. One half of its housing cavity has integrated protrusions on both sides of its cavity wall, and the other half of its housing cavity also has integrated protrusions on both sides of its cavity wall. Furthermore, since the clamping plate 19 has grooves on both sides of its cavity wall that match the protrusions in the first cylinder 10, one clamping plate 19 in the outer shell 18 is movably locked within one half of the housing cavity of the outer shell 18 after installation, and the protrusions on both sides are... The clamping plates 19 are movable and are located in the sliding grooves on both sides of the middle clamping plate 19, so that one clamping plate 19 is movable and positioned in one half of the shell cavity of the outer shell 18. The other clamping plate 19 in the outer shell 18 is arranged in the same way as the one clamping plate 19 in the outer shell 18, so that the other clamping plate 19 is movable and positioned in the other half of the shell cavity of the outer shell 18. When driven, the clamping plate 19 forms a sliding structure in the outer shell 18, and the sliding directions of the two clamping plates 19 are opposite.

[0078] Since a reset spring 21 is installed at the sliding connection between the clamping plate 19 and the outer shell 18, the reset spring 21 is symmetrically arranged about the central axis of the clamping plate 19 and is arranged in a "V" shape. After the reset spring 21 is installed, it is placed in the sliding groove of the clamping plate 19. Its middle part is fixedly connected to the sliding groove wall of the clamping plate 19 by bolts, and both ends slide against the protrusion in the outer shell 18. After the clamping plate 19 is driven to slide, the reset spring 21 is squeezed and undergoes elastic deformation.

[0079] Because a conductive metal sheet is fixedly snapped onto the side of the clamping plate 19 near the high-frequency transformer pin, the conductive metal sheet is adapted to the high-frequency transformer pin in a semi-circular arc structure. Because the connecting post 1801 is an integrated structure set in the center of the upper end of the outer shell 18, in a vertically upward state, a conductive metal post is fixedly connected inside the connecting post 1801, and the upper end of the conductive metal post extends outward through the upper end of the connecting post 1801, and the lower end of the conductive metal post extends into the shell cavity of the outer shell 18 through the lower end of the connecting post 1801. Because the conductive metal sheet in the clamping plate 19 is electrically connected to the conductive metal post in the connecting post 1801 through a wire, the wire between the clamping plate 19 and the connecting post 1801 is bent, which does not affect the sliding movement of the clamping plate 19. After the two clamping plates 19 slide in opposite directions, the two clamping plates 19 and the conductive metal sheet clamp and fix the high-frequency transformer pin, completing the electrical connection operation between the conductive metal sheet in the clamping plate 19 and the pin.

[0080] In summary, when the rotating disc 3 drives the housing 8 to rotate intermittently, the adjusting frame 22 continuously slides within the annular cavity of the annular cover 24, causing the pin 2201 to slide from the lower half of the annular groove 2501 through the inclined connecting groove 2503 to the upper half of the annular groove 2502. The position of the pin 2201 then moves upward again, causing the adjusting frame 22 to slide upward on the transverse seat in the housing 8. With the elastic deformation and reset of the first spring 23, the sleeve part in the linkage frame 20 slides upward on the connecting column 1801, and the plate part of the linkage frame 20 slides upward synchronously within the plate cavity of the clamping plate 19. Through the sliding engagement between the pin and the inclined groove 2001 in the clamping plate 19, and through the elastic deformation and reset of the reset spring 21, the two clamping plates 19 reset and slide in opposite directions, automatically releasing the clamping and fixing operation on the high-frequency transformer pin, that is, disconnecting the electrical connection between the connecting mechanism 9 and the high-frequency transformer pin.

[0081] Meanwhile, in the above technical solutions, according to Figure 1 , Figure 3 , Figure 8 and Figure 13 As shown, the test mechanism 4 is positioned directly above the rear empty slot in the rotating disk 3. Since the lower half-ring slot 2501 is located behind the annular cover 24, it is positioned below the test mechanism 4. The rotating disk 3 drives the housing 8 to rotate intermittently to the test mechanism 4. The connecting mechanism 9 can clamp and fix the high-frequency transformer pins to form an electrical connection. When the rotating disk 3 drives the housing 8 to rotate intermittently away from the test mechanism 4, the connecting mechanism 9 automatically releases the clamp and fixation of the high-frequency transformer pins and disconnects the electrical connection.

[0082] Because the arc dimension of the lower half-ring groove 2501 is smaller than that of the upper half-ring groove 2502, the left connection between the lower half-ring groove 2501 and the upper half-ring groove 2502 does not correspond to the feeding conveyor belt 5. That is, when the high-frequency transformer is being fed, the connecting mechanism 9 does not clamp and fix the pins therein. The right connection between the lower half-ring groove 2501 and the upper half-ring groove 2502 does not correspond to the unloading conveyor belt 6. That is, before the high-frequency transformer is unloaded, the connecting mechanism 9 releases the clamp and fixation of the pins therein in advance.

[0083] Meanwhile, in the above technical solutions, according to Figure 3 and Figure 10 As shown, the outwardly protruding end of the conductive metal post in the connecting post 1801 is adapted to the specifications and dimensions of the connecting post 1801 and is set in a hemispherical structure. The hemispherical end of the conductive metal post in the connecting post 1801 makes it easy for the connecting post 1801 to be accurately inserted into the test terminal 11. Furthermore, the lower end of the conductive metal sheet in the clamping plate 19 is set with a rounded chamfer, which makes it easy for the high-frequency transformer pin to be inserted between the two clamping plates 19.

[0084] Specifically, in this technical solution, the high-frequency transformer is tested using testing mechanism 4, according to... Figure 1 , Figure 3 and Figure 10 As shown, a test mechanism 4 for checking high-frequency transformers is provided on the bracket of the support frame 1. The test mechanism 4 includes a first cylinder 10 and a test terminal 11. The rotating disc 3 drives the housing 8 to rotate intermittently, so that the housing 8 above the feeding conveyor belt 5, along with the filled high-frequency transformer, rotates to directly below the test mechanism 4.

[0085] Because the upper section of the bracket in the support frame 1 is bent and positioned directly above the rotating disc 3, the first cylinder 10 is installed vertically and fixedly to the bent section of the bracket in the support frame 1 with bolts. Its output end extends downwards through the bracket in the support frame 1. The test terminal 11 is fitted onto and fixedly connected to the output end of the first cylinder 10 with bolts. The test housing 12 is fixedly installed on the bent section of the bracket in the support frame 1 with bolts. The test terminal 11 is electrically connected to the test housing 12 via a data cable. The test housing 12 and the test... The data line between the test terminals 11 is bent, which does not affect the lifting and lowering movement of the test terminals 11. The first cylinder 10 is activated to extend and operate. Driven by the first cylinder 10, the test terminals 11 move downward on the bracket in the support frame 1. After the test terminals 11 descend, they are connected to the connecting post 1801 by plugging in. The test terminals 11 and the conductive metal post in the connecting post 1801 are connected to form an electrical connection, completing the electrical connection between the high-frequency transformer, the connecting mechanism 9 and the test mechanism 4. The high-frequency transformer is then tested through the test chassis 12.

[0086] Specifically, in this technical solution, the high-frequency transformer is automatically picked up and placed from the housing 8 onto the unloading conveyor belt 6 by the feeding and picking mechanism 7 on the unloading conveyor belt 6. Based on the above, according to... Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the unloading conveyor belt 6 is located on the right side of the support frame 1. The overall structure of the unloading conveyor belt 6 is the same as that of the feeding conveyor belt 5, and the installation method of the unloading conveyor belt 6 is the same as that of the feeding conveyor belt 5. The difference is that the left end of the frame part of the unloading conveyor belt 6 is fixedly connected to the right side wall of the support frame 1 by bolts.

[0087] Because the unloading conveyor belt 6 is equipped with a feeding mechanism 7 for automatic loading and unloading of high-frequency transformers, the feeding mechanism 7 in the feeding conveyor belt 5 is arranged in the same way as the feeding mechanism 7 in the unloading conveyor belt 6. After the feeding mechanism 7 in the unloading conveyor belt 6 is installed, it corresponds to the area directly below the empty slot on the right side of the rotating disc 3. The rotating disc 3 drives the housing 8 to rotate intermittently, so that the housing 8 below the testing mechanism 4, along with the high-frequency transformer that has been tested, rotates to the top of the unloading conveyor belt 6. The second cylinder 15 is then activated to extend and operate. The "U"-shaped frame 13 is driven to rise on the unloading conveyor belt 6. The upper end of the longitudinal frame of the "U"-shaped frame 13 is aligned with the lower end of the housing 8. Once the tested high-frequency transformer is engaged, it is inserted into the "U"-shaped frame 13. The second cylinder 15 is then activated to retract and operate. The "U"-shaped frame 13 lowers the tested high-frequency transformer onto the unloading conveyor belt 6. After the "U"-shaped frame 13 is driven to slide downwards, the upper end of its longitudinal frame is flush with the conveyor belt of the unloading conveyor belt 6. The lower side of the tested high-frequency transformer is attached to the conveyor belt of the unloading conveyor belt 6. The unloading conveyor belt 6 is then activated, and the tested high-frequency transformer slides within the guide cavity formed by the combination of the limit guide plate and the frame through the conveyor belt. This completes the automatic loading and unloading of the tested high-frequency transformer and outputs the operation results.

[0088] Example 2:

[0089] Based on Embodiment 1, please refer to the following: Figures 14-17 The technical solution shown addresses the problem that the high-frequency transformer cannot be automatically locked after installation, thus failing to guarantee stability during testing. After the high-frequency transformer is inserted into the housing 8, the high-frequency transformer pushes the claw body in the pressing section of the fixing claw 26, causing the two fixing claws 26 to flip in opposite directions, thereby automatically clamping and locking the high-frequency transformer.

[0090] Specifically, in this technical solution, the high-frequency transformer is clamped and locked using the fixing claw 26, according to... Figure 14 , Figure 15 and Figure 16As shown, an integrated shaft column is provided at the upper end of the seat cavity of the longitudinal seat in the housing 8. Fixed claws 26 are provided in both longitudinal seats of the housing 8. Since the fixed claws 26 are arranged in a "V" shape, they are divided into two claw sections. One claw section is a clamping section and the other claw section is a pushing section. The end of the clamping section claw is fixedly engaged with the anti-slip rubber pad, and the end of the pushing section claw is arranged in an arc shape. After the fixed claws 26 are installed, their corners are movably sleeved on the shaft column of the longitudinal seat in the housing 8. The clamping section claw is movably inserted into the seat cavity of the longitudinal seat in the housing 8, and the end of the clamping section claw, together with the anti-slip rubber pad, extends outward. The pushing section claw is movably inserted into the seat cavity of the transverse seat in the housing 8, and the arc-shaped end of the pushing section claw extends outward. This makes the fixed claws 26 movable and positioned in the housing 8, and the fixed claws 26 form a rotating structure on the shaft column of the longitudinal seat in the housing 8.

[0091] Because a second torsion spring 27 is installed at the flip connection between the longitudinal seat body and the fixed claw 26 in the housing 8, the second torsion spring 27 is symmetrically arranged about the vertical central axis of the housing 8. The two second torsion springs 27 are respectively applied to the two fixed claws 26. After the second torsion spring 27 is installed, it is movably sleeved on the shaft column of the longitudinal seat body in the housing 8. One end of it is clamped on the fixed claw 26, and the other end is clamped on the seat cavity wall of the longitudinal seat body in the housing 8. When the high frequency transformer is automatically fed into the housing 8 by the feeding mechanism 7 in the feeding conveyor belt 5, the high frequency transformer is inserted into the housing 8, so that the upper side of the high frequency transformer is connected to the arc end of the pushing section claw body in the fixed claw 26 by pushing. The arc center of the arc end of the pushing section claw body in the fixed claw 26 coincides with the flip center of the fixed claw 26. After the fixed claw 26 is pushed, the fixed claw 26 flips and closes in the longitudinal seat body of the housing 8, and the second torsion spring 27 is compressed and undergoes elastic deformation.

[0092] Since the two fixing claws 26 in the housing 8 are set in opposite directions, after the fixing claws 26 are flipped and closed, the clamping section of the claw body, along with the anti-slip rubber pad, is connected to the side of the high-frequency transformer by pressing. The two fixing claws 26 automatically clamp and lock the high-frequency transformer stuck in the housing 8. In addition, by setting the anti-slip rubber pad on the clamping section of the fixing claw 26, the stability of the fixing claws 26 clamping the high-frequency transformer is ensured.

[0093] Because the unlocking block 28 is arranged in a "U" shape, consisting of a horizontal block and two vertical blocks, each of the two vertical blocks has a locking block 31 at its lower end. The locking block 31 has a through groove in its middle, and after installation, it is movably fitted onto the lower end of the vertical block in the unlocking block 28, and is movably locked within the cavity of the horizontal seat in the housing 8. The two locking blocks 31 correspond to two fixing claws 26. Furthermore, a third spring 32 is installed between the two locking blocks 31. The third spring 32 is symmetrically arranged about the central axis of the locking blocks 31, with one end fixedly connected to one locking block 31, and the other end... One end is fixedly connected to another locking block 31. After the fixing claw 26 is driven to flip and close, the pressing section of the fixing claw 26 slides in the seat cavity of the transverse seat in the housing 8. The elastic deformation of the third spring 32 resets the locking block 31, which slides in the seat cavity of the transverse seat in the housing 8. The sliding directions of the two locking blocks 31 are opposite. After the two locking blocks 31 slide, they are respectively connected to the arc-shaped ends of the pressing section of the two fixing claws 26 by a snap-fit ​​method to lock the flipped and closed fixing claw 26 and ensure the locking state of the fixing claw 26 for the high frequency transformer.

[0094] Specifically, in this technical solution, when unlocking the fixing claw 26, according to... Figure 15 , Figure 16 and Figure 17 As shown, the push rod assembly 30 is composed of two parts: a telescopic cylinder and a pressure head. After the push rod assembly 30 is installed, the telescopic cylinder is vertically fixed to the bent section of the bracket in the support frame 1 by bolts, and its output end extends downward through the bracket in the support frame 1. The pressure head is sleeved and fixedly connected to the output end of the telescopic cylinder by bolts. Since the unlocking block 28 is set in a "U" shape, it has a horizontal block and two vertical blocks. After the unlocking block 28 is installed, it is movably inserted in the middle position of the horizontal seat in the housing 8. Its upper horizontal block extends outward through the horizontal seat in the housing 8. The unlocking block 28 is connected to the push rod assembly 30 by pressing. When the telescopic cylinder in the push rod assembly 30 is started to extend and operate, the pressure head moves downward on the bracket in the support frame 1 by the telescopic cylinder. The pressure head presses and pushes the unlocking block 28, causing the unlocking block 28 to retract and slide in the middle position of the horizontal seat in the housing 8.

[0095] Because a second spring 29 is installed at the sliding connection between the transverse seat body and the unlocking block 28 in the housing 8, the second spring 29 is symmetrically arranged about the central axis of the unlocking block 28. After the second spring 29 is installed, one end is fixedly connected to the transverse block body of the unlocking block 28, and the other end is fixedly connected to the seat cavity wall of the transverse seat body in the housing 8, so that the unlocking block 28 is positioned on the housing 8 in a movable state. After the unlocking block 28 retracts and slides, the second spring 29 is compressed and undergoes elastic deformation. In addition, when the push rod assembly 30 loses its pressure on the unlocking block 28, the elastic deformation of the second spring 29 is used to reset, so that the unlocking block 28 resets and extends and slides.

[0096] Because the lower end of the longitudinal block in the unlocking block 28 is provided with an inclined sidewall, and the inclined sidewalls on the two longitudinal blocks are arranged in opposite directions, and because the through groove in the locking block 31 is provided with an inclined groove wall, and the inclined groove walls in the two locking blocks 31 are arranged in opposite directions, the inclined sidewall of the longitudinal block in the unlocking block 28 and the inclined groove wall in the through groove of the locking block 31 are slidably attached together. After the unlocking block 28 is driven to retract and slide, the sliding cooperation between the inclined sidewall of the unlocking block 28 and the inclined groove wall of the locking block 31 causes the locking block 31 to reset and slide in the seat cavity of the transverse seat in the housing 8, and the third spring 32 is compressed and undergoes elastic deformation. After the two locking blocks 31 reset and slide in opposite directions, they respectively unlock the two fixing claws 26. The elastic deformation of the second torsion spring 27 resets and drives the fixing claws 26 to reset, flip and unfold in the longitudinal seat in the housing 8. After the two fixing claws 26 flip and unfold, they release the lock on the high-frequency transformer.
