Description

Technical Field

[0001] This utility model relates to the field of high-frequency transformer technology, and in particular to a CDD testing station for high-frequency transformers. Background Technology

[0002] High-frequency transformers are power transformers that operate at frequencies exceeding intermediate frequencies (10kHz). They are primarily used in high-frequency switching power supplies, and also in high-frequency inverter power supplies and high-frequency inverter welding machines. High-frequency transformers integrate multiple functions such as protection, monitoring, control, and communication, making them ideal electrical units for constructing intelligent high-frequency transformers.

[0003] In the manufacturing process of high-frequency transformers, after the finished product is wound and soldered, it needs to be identified and inspected to determine whether there are any defects in the assembly process. However, the existing detection method that uses a CDD camera to take pictures and combine with image recognition algorithms has high requirements for ambient light. Images taken in dark or weak light conditions are prone to causing a decrease in the accuracy of subsequent finished product measurements. Therefore, we propose a CDD testing station for high-frequency transformers to solve the above problems. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies. This invention proposes a CDD (Continuous Digital Detection) testing station for high-frequency transformers. It enables image detection of small high-frequency transformers and simultaneously overcomes the existing problem of large detection errors caused by weak ambient light.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a CDD testing station for high-frequency transformers, comprising: a mounting frame and a lifting component and a CDD testing camera fixed on the front of the mounting frame. The lifting component is used to drive the CDD testing camera to move up and down. The CDD testing camera is placed vertically and has a corresponding illumination component at the bottom. The illumination component is arranged in multiple levels and includes a central supplementary optical disc and a focusing supplementary light block from top to bottom. The inner wall of the central supplementary optical disc is provided with a first LED. The focusing supplementary light block has an opening on one side and a second LED is placed in the opening. The central supplementary optical disc and the focusing supplementary light block are each electrically connected to a power supply block to supply power to the first LED and the second LED. The mounting frame is also movably fixed with an auxiliary support at the interval between the CDD testing camera and the central supplementary optical disc. An auxiliary supplementary optical disc coaxially arranged with the lens of the CDD testing camera is also fixed on the auxiliary support. The inner wall of the auxiliary supplementary optical disc is provided with a third LED.

[0006] Furthermore, the lifting component includes a servo motor, a vertical slide rail, a lead screw, a nut seat, and a camera mounting plate. The vertical slide rail is fixed to the front of the mounting frame, and its upper and lower ends are rotatably connected to the lead screw. The servo motor is fixed to the top of the vertical slide rail, and its output end is coaxially fixed to the lead screw. The nut seat is threaded onto the lead screw, and its top is fixed integrally with the camera mounting plate. The top of the camera is bolted to the camera mounting plate.

[0007] Furthermore, the CDD inspection camera includes at least two sets, and the bottom of each set is located on the central supplementary optical disc. The auxiliary supplementary optical disc corresponds to the bottom of at least one set of the CDD inspection camera.

[0008] Furthermore, the first LED bead comprises multiple layers, each layer being circumferentially distributed around the center line of the CDD detection camera lens, and the multiple layers of the first LED bead are tilted downwards and all point towards the center line of the CDD detection camera lens.

[0009] Furthermore, the third LED bead is distributed and fixed in the same way as the first LED bead.

[0010] Furthermore, the focusing fill light block includes two sets, both of which are strip-shaped structures. The two focusing fill light blocks are inclinedly arranged at the bottom of the central fill light disc and are symmetrical about the center of the central fill light disc. The second lamp bead is set to point towards the center line of the CDD detection camera lens.

[0011] Furthermore, the mounting frame is also provided with a position sensor on the side corresponding to the vertical slide rail, and the camera fixing plate is also fixed with a contact sensing piece and the position sensor on the side corresponding to the position sensor. The position sensor is electrically connected to the servo motor.

[0012] Furthermore, the mounting frame is provided with a connecting rod and a connecting plate at the bottom of the corresponding lifting component on the front side. The connecting plate is used to hollowly fix the central filler disc, and the connecting rod is used to fix the focusing filler block and the auxiliary filler disc through the auxiliary bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model include: the servo motor drives the lead screw to rotate and position within the vertical slide rail, and the nut group can move up and down along the lead screw axis under the action of the corresponding thread, thereby driving the camera fixing plate to rise and fall together, which facilitates the focusing operation of the subsequent CDD inspection camera, and simultaneously coordinates with the illumination of the center supplementary optical disc, the focusing supplementary light block and the auxiliary supplementary optical disc to ensure the clarity of the subsequent captured images under sufficient lighting conditions.

[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0020] According to one embodiment of the present invention, in conjunction with Figures 1-3 As shown.

[0021] like Figure 1 and Figure 3As shown, in this embodiment, the CDD testing station for high-frequency transformers includes: a mounting frame 1, a lifting component 2 and a CDD testing camera 3 fixed to the front of the mounting frame 1. The lifting component 2 is used to drive the CDD testing camera 3 to move up and down. The CDD testing camera 3 is placed vertically and has a corresponding illumination component 4 at the bottom. The illumination component 4 is arranged in multiple levels and includes a central fill light disc 5 and a focusing fill light block 6 from top to bottom. The inner wall of the central fill light disc 5 is provided with a first LED 7. The focusing fill light block 6 has an opening on one side and a second LED 8 is laid in the opening. The central fill light disc 5 and the focusing fill light block 6 are both electrically connected to a power supply block 9 to supply power to the first LED 7 and the second LED 8. The mounting frame 1 is also movably fixed with an auxiliary support 10 at the interval between the CDD testing camera 3 and the central fill light disc 5. An auxiliary fill light disc 11 is also fixed on the auxiliary support 10 and is coaxially arranged with the lens of the CDD testing camera 3. The inner wall of the auxiliary fill light disc 11 is provided with a third LED 12.

[0022] The lifting process can be driven by various structures, such as common ball screws 15, linear cylinders, etc. In this embodiment, for example... Figure 2 and Figure 3 As shown, the lifting component 2 includes a servo motor 13, a vertical slide rail 14, a lead screw 15, a nut seat 16, and a camera mounting plate 17. The vertical slide rail 14 is fixed to the front of the mounting frame 1, and its upper and lower ends are rotatably connected to the lead screw 15. The servo motor 13 is fixed to the top of the vertical slide rail 14, and its output end is coaxially fixed to the lead screw 15. The nut seat 16 is threaded to the lead screw 15, and its top is fixed to the camera mounting plate 17 as a whole. The top of the camera is bolted to the camera mounting plate 17.

[0023] More specifically, in the actual structure of this testing station, the CDD testing camera 3 includes at least two sets, and the bottom of each set is located on the central supplementary optical disc. The auxiliary supplementary optical disc 11 corresponds to the bottom of at least one set of the CDD testing camera 3. Correspondingly, for the enhancement of the light, in order to further improve the illumination effect and uniformity, in this embodiment, the first LED bead 7 includes multiple layers, each layer being circumferentially distributed around the center line of the lens of the CDD testing camera 3. The multiple layers of the first LED bead 7 are tilted downwards and all point towards the center line of the lens of the CDD testing camera 3. The third LED bead 12 is distributed and fixed in the same way as the first LED bead 7. The focusing supplementary light block 6 includes two sets, both of which are strip structures. The two focusing supplementary light blocks 6 are tilted and arranged at the bottom of the central supplementary optical disc 5, and are symmetrical about the center of the central supplementary optical disc 5. The second LED bead 8 is positioned pointing towards the center line of the lens of the CDD testing camera 3.

[0024] Specifically, for the connection between each supplementary lighting structure and the mounting frame 1, the front of the mounting frame 1 is also provided with a connecting rod 20 and a connecting plate 21 at the bottom of the corresponding lifting component 2. The connecting plate 21 is used to hollowly fix the central supplementary lighting disc 5, and the connecting rod 20 is used to fix the focusing supplementary lighting block 6 and the auxiliary supplementary lighting disc 11 through the auxiliary bracket 10.

[0025] This three-layer reinforcement light structure design can greatly overcome the impact of insufficient or chaotic ambient light on the accuracy of CDD image detection. All three layers of light are directed towards the center line of the CDD detection camera's three lenses. This ensures sufficient illumination at the bottom of the lens axis, allowing for clear capture of every detail of the high-frequency transformer during subsequent image acquisition and recognition, thus avoiding errors in the subsequent judgment of the finished product.

[0026] Similarly, the present invention also provides a position sensor 18 on the side of the mounting frame 1 corresponding to the vertical slide rail 14, and a contact sensing piece 19 and the position sensor 18 are fixed on the side of the camera fixing plate 17 corresponding to the position sensor 18. The position sensor 18 is electrically connected to the servo motor 13.

[0027] After the servo motor 13 drives the output, it can drive the lead screw 15 to rotate and position within the vertical slide rail 14. Under the action of the synchronous thread, the nut seat 16 can move up and down along the axis of the lead screw 15, and then drive the camera fixing plate 17 to rise and fall together. The purpose of raising and lowering is twofold: first, to facilitate the focusing operation of the CDD detection camera 3; and second, to assist in the illumination of the center supplementary optical disc 5, the focusing supplementary light block 6, and the auxiliary supplementary optical disc 11, so as to ensure the clarity of the subsequent captured images under sufficient lighting conditions. The overall structure is reasonably designed, practical and reliable.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
