Description

Technical Field

[0001] This utility model belongs to the field of surface mount transformer processing technology, and more specifically, it relates to a surface mount transformer pin correction device. Background Technology

[0002] Surface mount transformers are a common type of electrical equipment. The function of a transformer is to transform current into voltage. The pins of surface mount transformers are made of relatively soft material, which makes them prone to bending during the production process due to factors such as transportation, processing, or assembly.

[0003] When calibrating the pins of a surface mount transformer, workers typically use plug gauges and homemade tools to calibrate each pin individually. This method is not only inefficient and labor-intensive, but also unsuitable for large-scale production. Furthermore, the calibration accuracy relies entirely on the worker's experience, easily leading to inadequate or over-calibration that could damage the pins. Therefore, this paper researches and improves upon existing structures and shortcomings to provide a surface mount transformer pin calibration device, aiming to achieve greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a surface mount transformer pin calibration device, which is achieved by the following specific technical means:

[0005] A surface mount transformer pin alignment device includes a workbench for placing the surface mount transformer. A support platform is located at the center of the top of the workbench, and a mounting base corresponding to the surface mount transformer is installed at the top of the support platform. A clamping mechanism for pressing the surface mount transformer is installed on one side of the workbench. Side plates are provided on both sides of the support platform, and each side plate has a sliding groove. A lower fixing frame is symmetrically installed at the top of the workbench, and the bottom sides of the lower fixing frame are slidably installed within the sliding grooves. A U-shaped frame is connected to the outer side of the lower fixing frame. Two sets of electric push cylinders are vertically installed at the bottom of the horizontal section of the U-shaped frame. The output ends of the electric push cylinders are connected to an upper fixing frame. An upper clamp is installed at the bottom of the upper fixing frame, and a lower clamp is installed at the top of the lower fixing frame. An arc-shaped groove matching the number of pins is provided on the opposite side of both the upper and lower clamps.

[0006] As a preferred embodiment of this utility model, a protective pad is fitted inside the arc-shaped groove.

[0007] As a preferred technical solution of this utility model, two sets of guide rails are installed on one side of the C-shaped frame, and a connecting block is provided at the bottom end of each set of guide rails. One side of each set of connecting blocks is fixedly connected to one side of the lower fixed frame. A guide block corresponding to and matching the guide rail is installed on one side of the upper fixed frame, and the guide block is slidably connected to the outside of the guide rail.

[0008] As a preferred technical solution of this utility model, it also includes a drive mechanism, which includes two sets of bidirectional screws respectively installed inside the slide groove. Each bidirectional screw has a slider symmetrically connected to its outer side, and the slider is fixedly connected to the bottom end of the lower fixed frame. A protective cover is connected to one side of both sets of side plates. One end of each set of bidirectional screws extends into the interior of the protective cover and is equipped with a synchronous pulley. The two sets of synchronous pulleys are connected by a synchronous belt. A reduction motor is connected to one side of the protective cover, and the reduction motor is driven by one of the sets of synchronous pulleys.

[0009] As a preferred embodiment of this utility model, the upper and lower fixed frames are provided with limit grooves on both sides, and the upper and lower clamps are provided with limit blocks that are inserted into the limit grooves on both sides.

[0010] As a preferred technical solution of this utility model, an installation groove is provided inside the upper fixed frame and the lower fixed frame and between the two sets of corresponding limiting grooves. A magnetic suction plate is installed inside the installation groove and is magnetically connected to the upper clamp and the lower clamp respectively. An installation groove is provided at the top of the support platform. A magnetic suction plate is installed inside the installation groove and is magnetically connected to the fixed seat.

[0011] As a preferred technical solution of this utility model, the clamping mechanism includes a connecting frame fixedly installed on one side of the workbench. An electric push cylinder is installed at the top of the horizontal section of the connecting frame. The output end of the electric push cylinder extends through to the bottom end of the connecting frame and is fixedly installed with a clamping plate. A rubber pad is provided at the bottom end of the clamping plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention, through the configuration of a lower fixed frame, a U-shaped frame, an electric push cylinder, an upper fixed frame, an upper clamp, and a lower clamp, along with a drive mechanism, enables simultaneous correction of multiple sets of pins on both sides of a surface mount transformer. This significantly improves correction efficiency and accuracy, avoids the tediousness and errors of manual correction, reduces human intervention, enhances operational convenience and consistency, and lowers labor intensity. The inclusion of a fixed base, limiting groove, and limiting block, along with magnetic plates one and two, makes the installation and replacement of the fixed base, upper clamp, and lower clamp more convenient, improving the device's versatility and adapting to the placement requirements of different types of surface mount transformers. The clamping mechanism securely presses the surface mount transformer onto the fixed base, and with the addition of rubber pads, prevents displacement or shaking of the transformer during pin correction, ensuring accurate correction position and avoiding indentations or damage to the transformer surface.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a pin alignment device for a surface mount transformer (SMT) transformer, comprising a workbench 1 for placing the SMT transformer 2, a support platform 4 at the center of the top of the workbench 1, a fixing seat 5 corresponding to the SMT transformer 2 mounted on the top of the support platform 4, and a clamping mechanism for clamping the SMT transformer 2 mounted on one side of the workbench 1; side plates 6 are provided on both sides of the support platform 4 on the workbench 1, and each side plate 6 has a sliding groove inside; and lower fixing frames are symmetrically mounted on the top of the workbench 1. 7. The bottom sides of the lower fixed frame 7 are slidably installed in the slide grooves respectively; the outer side of the lower fixed frame 7 is connected to the C-shaped frame 8, and the bottom of the horizontal section of the C-shaped frame 8 is vertically installed with two sets of electric push cylinders 9. The output ends of the electric push cylinders 9 are connected to the upper fixed frame 10. The bottom end of the upper fixed frame 10 is equipped with an upper clamp 11, and the top end of the lower fixed frame 7 is equipped with a lower clamp 12. The upper clamp 11 and the lower clamp 12 are respectively provided with arc-shaped grooves on their opposite sides that match the number of PINs 3.

[0028] The arc-shaped groove is slightly larger than the pin 3, and a protective pad is attached to the inside of the arc-shaped groove. The arc-shaped groove is slightly larger than the pin 3, which provides adequate space for the pin 3 to move during calibration and avoids excessive compression of the pin 3 during calibration. The protective pad attached inside has a buffering effect, which can reduce the friction and collision between the pin 3 and the arc-shaped groove during calibration, effectively preventing the pin 3 from being scratched, bent or broken, and ensuring the integrity of the pin 3.

[0029] Two sets of guide rails 13 are installed on one side of the C-shaped frame 8. Each set of guide rails 13 has a connecting block at its bottom end. One side of each set of connecting blocks is fixedly connected to one side of the lower fixed frame 7. A guide block 14 corresponding to the guide rails 13 is installed on one side of the upper fixed frame 10. The guide block 14 is slidably connected to the outside of the guide rails 13, which strictly limits the movement trajectory of the upper fixed frame 10, ensuring that the upper clamp 11 and the lower clamp 12 can be accurately aligned. This ensures that each set of pins 3 can be accurately corrected, while also increasing the stability of the upper fixed frame 10 during the lifting process, reducing shaking, and making the correction force of the upper clamp 11 on the pins 3 more stable.

[0030] The system also includes a drive mechanism, which comprises two sets of bidirectional screws 15 respectively installed inside the slide groove. Slider 16s are symmetrically connected to the outer sides of each bidirectional screw 15, and the sliders 16 are fixedly connected to the bottom end of the lower fixed frame 7. A protective cover 17 is connected to one side of each of the two sets of side plates 6. One end of each set of bidirectional screws 15 extends into the protective cover 17 and is equipped with a synchronous pulley. The two sets of synchronous pulleys are connected by a synchronous belt 18. A reduction motor 19 is connected to one side of the protective cover 17, and the reduction motor 19 is connected to one of the synchronous pulleys. This adjustment method offers high precision, enabling automated adjustment of the lower fixed frame 7 position. It also allows for rapid adjustment of the lower clamp 12 to the position corresponding to the PIN 3, thus adapting to different product specifications and reducing errors and time associated with manual adjustment.

[0031] The upper fixing frame 10 and the lower fixing frame 7 are provided with limiting grooves on both sides of their interior. The upper clamp 11 and the lower clamp 12 are respectively provided with limiting blocks 20 that are inserted into the limiting grooves on both sides. This can quickly position the installation position of the upper clamp 11 and the lower clamp 12, ensuring their precise alignment. At the same time, it can also limit the lateral movement of the upper clamp 11 and the lower clamp 12 during the calibration process, making their connection more secure and preventing the upper clamp 11 and the lower clamp 12 from loosening during calibration and affecting the calibration effect.

[0032] The upper fixing frame 10 and the lower fixing frame 7 each have an installation slot 1 inside, located between the two sets of corresponding limiting slots. Each installation slot 1 has a magnetic suction plate 21 that is magnetically connected to the upper clamp 11 and the lower clamp 12. The top of the support platform 4 has an installation slot 2. The installation slot 2 has a magnetic suction plate 22 that is magnetically connected to the fixing seat 5. This allows the installation and replacement of the upper clamp 11, the lower clamp 12 and the fixing seat 5 to be fixed by magnetic force without the need for tools. The installation and replacement can be done simply by placing them on the ground. This makes the operation convenient and can quickly adapt to the calibration requirements of different models of surface mount transformers 2 and pins 3. At the same time, the magnetic connection has a certain clamping force, which can ensure that the upper clamp 11, the lower clamp 12 and the fixing seat 5 will not easily shift during the calibration process, thus improving the flexibility and versatility of the device.

[0033] The clamping mechanism includes a connecting frame 23 fixedly installed on one side of the workbench 1. An electric push cylinder 24 is installed at the top of the horizontal section of the connecting frame 23. The output end of the electric push cylinder 24 extends to the bottom of the connecting frame 23 and is fixedly installed with a clamping plate 25. A rubber pad is provided at the bottom of the clamping plate 25, and the rubber pad is in contact with the top of the chip transformer 2. It can generate sufficient pressure to firmly fix the chip transformer 2 on the fixing base 5, preventing the chip transformer 2 from shifting due to force during calibration and ensuring calibration accuracy. At the same time, the rubber pad is soft and elastic, and will not cause indentations or scratches on the surface of the chip transformer 2 during the clamping process. It can achieve reliable fixation and protect the appearance quality of the product, meeting the appearance requirements of product production.

[0034] The working principle of this embodiment:

[0035] When using the calibration device, first select a suitable fixing base 5 and fix it on the support platform 4 with the cooperation of magnetic suction plate 22. Then place the chip transformer 2 inside the fixing base 5 and start the electric push cylinder 24. The electric push cylinder 24 drives the pressure plate 25 to move downward, so that the rubber pad at the bottom of the pressure plate 25 is tightly attached to the top of the chip transformer 2, thereby firmly pressing the chip transformer 2 on the fixing base 5 to prevent displacement during the calibration process.

[0036] Next, select appropriate upper clamp 11 and lower clamp 12 according to the positions of the pins 3 on both sides of the surface mount transformer 2, and use magnetic suction plate 21 to fix them inside the upper fixing frame 10 and lower fixing frame 7 respectively. Then, start electric push cylinder 9 to push the upper fixing frame 10 downward. At the same time, the guide block 14 on one side of the upper fixing frame 10 slides along the guide rail 13 on one side of the C-shaped frame 8. When the upper clamp 11 and lower clamp 12 are closed, the arc grooves on the upper clamp 11 and lower clamp 12 respectively wrap around the pins 3 from the upper and lower sides. Then, start the geared motor 19. With the cooperation of the synchronous pulley and synchronous belt 18, the two sets of bidirectional screws 15 and the slider 16 connected to the bidirectional screws 15 slide in the groove. The internal synchronous movement allows the upper clamp 11 and lower clamp 12 to correct the deformed pin 3 under the constraint of the arc groove, thereby restoring the pin 3 to a regular state. After correction, the shaped frame 8 returns to its initial position, the electric push cylinder 1 9 retracts, driving the upper fixed frame 10 and upper clamp 11 to move upward and separate from the lower clamp 12. The electric push cylinder 24 retracts, driving the pressure plate 25 to move upward and release the pressure on the chip transformer 2. The corrected chip transformer 2 can then be removed from the fixed seat 5, completing the entire pin 3 correction process. For chip transformers 2 or pins 3 of different specifications, only the corresponding fixed seat 5, upper clamp 11 and lower clamp 12 need to be replaced.

[0037] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
