Description

Technical Field

[0001] This utility model relates to the field of high-frequency transformer welding technology, and in particular to a welding point device for the rear shielding wire of a high-frequency transformer. Background Technology

[0002] A high-frequency transformer is a small, high-efficiency power converter that uses a special magnetic core and coil to rapidly "oscillate" and transmit electrical energy, thereby changing voltage or isolating circuits. Because of its high operating frequency, it is much smaller than a regular transformer, but more efficient, and is a core component of modern switching power supplies, chargers and other electronic devices.

[0003] Because the solder joints of the transformer's shielding wire and pins are higher than the PCB board after being wrapped, they need to be pressed together by high-temperature heating to achieve the required height. Currently, this is usually done manually using a high-temperature soldering iron to apply tin. After the tin melts, the wire is pressed to control the height of the shielding wire to prevent the solder joint from floating. This method is inefficient and requires a lot of manual labor. Therefore, a device for pressing the solder joints of the high-frequency transformer's rear shielding wire is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a welding point device for the post-shielding wire of a high-frequency transformer, which solves the problems of low efficiency and high difficulty in the current shielding wire welding method.

[0005] To achieve this objective, the present invention adopts the following technical solution: A bonding device for the post-shielding wire of a high-frequency transformer, comprising: Base; A positioning plate, which is movable vertically on the base, has a product body mounted on it. Pins of the product body pass through the positioning plate, and the bottom of the pins extends to the bottom of the positioning plate. The welding assembly is disposed on the base and located below the positioning plate.

[0006] Furthermore, the base is configured as a box-shaped structure, and a mounting bracket is detachably connected to the base, the mounting bracket being configured as a gantry structure.

[0007] Furthermore, the welding assembly includes a heat-conducting block mounted on the top of the inner wall of the base and a wire-pressing pin disposed on the heat-conducting block, the top of the wire-pressing pin passing through the base and extending to the bottom of the positioning plate.

[0008] Furthermore, the welding assembly also includes a temperature controller installed inside the base and a heating wire installed at the bottom of the heat-conducting block, wherein the temperature controller and the heating wire are electrically connected.

[0009] Furthermore, a driving component is installed at the bottom of the mounting bracket cross arm, and a pressure block is installed at the output end of the driving component. The pressure block is located above the positioning plate and moves vertically up and down.

[0010] Furthermore, the pressure block is configured as a flexible structure, and the bottom of the pressure block is configured as a conical structure.

[0011] Furthermore, a time relay is installed inside the base, and the time relay is electrically connected to the drive component.

[0012] Furthermore, a buffer hole is provided at the top of the base, located at the position of the positioning plate, and a buffer rod is movable up and down inside the buffer hole, with the top of the buffer rod abutting against the positioning plate.

[0013] Furthermore, a pressing plate is fixed to the outside of the buffer rod, and a spring is also sleeved on the outside of the buffer rod, with the two ends of the spring abutting against the pressing plate and the base, respectively.

[0014] Furthermore, the bottom of the positioning plate has an opening at the position of the buffer rod, and the buffer rod is inserted into the opening.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The positioning plate on the base, in conjunction with the welding assembly, allows the product body to move up and down. During this movement, the product body's pins come into contact with the welding assembly. Simultaneously, the worker places solder bars in the same positions on the pins. After the solder bars melt, they wrap around the pins. The wire-pressing pins in the welding assembly then press and shape the pins, ensuring that the pin length of the product body reaches the appropriate length and that the shielding wire reaches the controlled height for wrapping. This satisfies the requirement that the subsequent solder joints do not float, eliminating the need for manual high-temperature soldering. Furthermore, the positioning plate can be changed and replaced according to different specifications of the product body model, facilitating the processing of different product body models.

[0016] 2. By using the buffer rod, the pressing plate on the buffer rod, and the spring, after the positioning plate is pressed down to make the product body contact the welding component and the processing is completed, the positioning plate is released. Under the action of the spring, the positioning plate will automatically move upward, driving the product body to move and causing the pins of the product body to detach from the welding component.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model embodiment provides a bonding device for the post-shielding wire of a high-frequency transformer. Please refer to [link / reference]. Figures 1-3 The product includes: a base 1, a positioning plate 4 and a welding assembly. The positioning plate 4 moves up and down on the base 1. The product body 5 is provided on the positioning plate 4. The pins of the product body 5 pass through the positioning plate 4 and the bottom of the pins extends to the bottom of the positioning plate 4. The welding assembly is located on the base 1 and below the positioning plate 4.

[0025] like Figures 1-3 As shown, the base 1 serves as the supporting foundation for the entire pressure welding equipment, providing space for the installation and fixing of other components. The stable base 1 ensures that the welding accuracy will not be affected by shaking or displacement during the operation of the equipment.

[0026] The positioning plate 4 can adjust the position of the product body 5 by moving up and down, so that its pins can accurately contact the welding components below, realizing flexible welding operations. This allows the equipment to adapt to welding product bodies 5 with different height requirements, and can also weld product bodies 5 at different heights, improving the versatility and flexibility of the equipment.

[0027] The product body 5 is movably mounted on the positioning plate 4, and extends to the bottom through the positioning plate 4 via pins, enabling the pins to accurately mate with the welding components, preparing for welding and ensuring the stability of the product body 5 during the welding process. At the same time, the accurate extension of the pins ensures the precision of the welding position, which is beneficial to improving the welding quality.

[0028] The welding assembly is located below the positioning plate 4. When the positioning plate 4 moves the product body 5 down, the pins can contact the welding assembly to realize the welding operation. That is, the contact timing between the pins and the welding assembly is controlled by the up and down movement of the positioning plate 4, which improves the automation level and ease of operation of the welding.

[0029] Specific process: Place the high-frequency transformer product body 5 to be soldered on the positioning plate 4, ensuring that the pins of the product body 5 accurately pass through the positioning plate 4 and extend to the bottom. At this time, the positioning plate 4 is in an initial high position, and the soldering assembly is located below the positioning plate 4 waiting. The positioning plate 4 is controlled to move downward by the driving device (driving component 3), and the positioning plate 4 drives the product body 5 to descend together. As the positioning plate 4 descends, the pins of the product body 5 gradually approach the soldering assembly. When the positioning plate 4 descends to the appropriate position, the pins of the product body 5 contact the soldering assembly. At this time, the operator places the solder bar between the pins and the soldering assembly. At the same contact point, the wire guide pin 7 transfers heat to the pin and solder bar, melting the solder bar. The molten solder bar wraps around the pin, achieving initial soldering. After the pin is tinned, the wire guide pin 7 in the soldering assembly performs a wire crimping operation on the pin, ensuring that the pin length of the product body 5 reaches the appropriate length. This ensures that the shielding wire reaches the control height for wrapping the pin, meeting the requirement that the subsequent solder joints do not float. After completing the soldering and wire crimping, the drive device controls the positioning plate 4 to move upward, driving the product body 5 back to the initial position. The operator can then remove the soldered product body 5 to proceed with the soldering operation of the next product.

[0030] Please see Figure 1 and Figure 2 The base 1 is designed as a box-shaped structure, and the mounting bracket 2 is detachably connected to the base 1. The mounting bracket 2 is designed as a gantry structure.

[0031] like Figure 1 and Figure 2 As shown, the box-shaped structure has a large internal space, which can be used to install and accommodate various electrical components, wiring and other auxiliary parts of the equipment, making the equipment structure more compact and orderly.

[0032] Mounting bracket 2 provides mounting positions for other key components of the equipment (such as drive unit 3, pressure block 301, etc.), enabling these components to be accurately positioned and fixed, ensuring the relative positional accuracy between various parts of the equipment. The detachable design allows mounting bracket 2 to be flexibly replaced or adjusted according to different production needs, equipment upgrades or maintenance situations, improving the adaptability and flexibility of the equipment.

[0033] The gantry structure has high strength and stability, and can withstand large pressure and load. It ensures that the mounting frame 2 will not deform or be damaged when the driving component 3 drives the pressure block 301 to apply pressure downward. It also ensures that the pressure block 301 can move vertically up and down accurately and apply stable pressure to the product body 5 on the positioning plate 4.

[0034] Please see Figure 1 and Figure 3The welding assembly includes a heat-conducting block 6 installed on the top of the inner wall of the base 1 and a wire guide pin 7 provided on the heat-conducting block 6. The top of the wire guide pin 7 passes through the base 1 and extends to the bottom of the positioning plate 4. The welding assembly also includes a temperature controller 8 installed inside the base 1 and a heating wire 801 installed at the bottom of the heat-conducting block 6. The temperature controller 8 and the heating wire 801 are electrically connected.

[0035] like Figure 1 and Figure 3 As shown, the heat-conducting block 6, as a medium for heat conduction and storage, is fixed to the top of the inner wall of the base 1, providing a stable heat base for the wire pressing needle 7. It can receive the heat generated by the heating wire 801 and evenly transfer the heat to the wire pressing needle 7, ensuring that the wire pressing needle 7 has a continuous and uniform heat supply during the welding and wire pressing process.

[0036] The wire crimping pin 7 integrates heating, soldering, and wire crimping functions. Its design extending below the positioning plate 4 ensures that the wire crimping pin 7 can accurately contact the pins of the product body 5 when the positioning plate 4 lowers the product body 5. During the soldering stage, the wire crimping pin 7 heats the pins through the heat transfer block 6, melting the solder and wrapping it around the pins. During the wire crimping stage, the wire crimping pin 7 applies pressure to the soldered pins, pressing them into a suitable length and shape to meet the height control requirements of the shielding wire wrapping. Specifically, the wire crimping pin 7 has an opening inside, into which the pins are inserted. After the solder melts inside the wire crimping pin 7, the opening structure facilitates the molten solder wrapping around the pins. After wrapping, the wire crimping pin 7 presses the pins into shape. The wire crimping pin 7 is made of tungsten rod with 99% pure tungsten to ensure that it leaves no solder residue, is malleable, can be heated to 400°C without deformation, reacts quickly with solder without adhesion, and is wear-resistant.

[0037] The temperature controller 8 is the core component for controlling the welding temperature. It is installed inside the base 1 for easy connection and integration with other electrical components. It can monitor the temperature change of the wire crimping needle 7 in real time and accurately control the working state of the heating wire 801 according to the set temperature value, so as to ensure that the temperature of the wire crimping needle 7 is always kept within a suitable range during the welding and crimping process. The structure of the temperature controller 8 is well known to those skilled in the art. The key point is to use the temperature controller 8 to control the temperature of the heating wire 801 so that the wire crimping needle 7 can be heated at a suitable temperature. It will not be described in detail in this embodiment.

[0038] The heating wire 801 is the source of heat generation. Installed at the bottom of the heat-conducting block 6, it can directly transfer heat to the heat-conducting block 6, and then the heat-conducting block 6 efficiently conducts the heat to the wire guide pin 7. The temperature controller 8 can obtain the working status information of the heating wire 801 in real time, and precisely control the power supply of the heating wire 801 according to the set temperature parameters. When the temperature of the wire guide pin 7 is lower than the set value, the temperature controller 8 controls the heating wire 801 to be powered on and heated; when the temperature reaches the set value, the temperature controller 8 controls the heating wire 801 to be powered off and stop heating, thereby realizing automatic temperature regulation.

[0039] Please see Figures 1-3 The bottom of the cross arm of the mounting bracket 2 is equipped with a drive component 3. The output end of the drive component 3 is equipped with a pressure block 301. The pressure block 301 is located above the positioning plate 4 and moves vertically up and down. The pressure block 301 is set as a flexible structure. The bottom of the pressure block 301 is set as a conical structure. The base 1 is equipped with a time relay 9. The time relay 9 is electrically connected to the drive component 3.

[0040] like Figures 1-3 As shown, the drive component 3 is the power source for the automated operation of the entire equipment. It is installed at the bottom of the cross arm of the mounting frame 2, in a reasonable and stable position, which can provide sufficient and stable power for the subsequent movement of the pressing block 301, ensuring that the pressing block 301 can move according to the set requirements. The use of drive component 3 realizes the automated operation of the equipment, which greatly improves production efficiency and reduces the intensity of manual labor and human error compared with manual operation. At the same time, the stable power output ensures the accuracy and consistency of the pressing block 301's movement, which is conducive to improving product quality.

[0041] The pressure block 301 is a component that directly acts on the positioning plate 4. It transmits the power generated by the driving component 3 to the positioning plate 4 or the product body 5, so that the positioning plate 4 or the product body 5 can move up and down as required, thereby driving the product body 5 to descend, so that the pins of the product body 5 can contact the welding components to complete the subsequent welding and wire pressing operations.

[0042] When the flexible pressure block 301 contacts the positioning plate 4, it can play a certain buffering role. When the driving component 3 drives the pressure block 301 to move downward and contact the positioning plate 4, the flexible structure can absorb part of the impact force, avoid damage to the positioning plate 4 and the product body 5 due to rigid contact, and also reduce the noise generated during equipment operation.

[0043] The bottom of the cone-shaped pressure block 301 can concentrate the pressure on a small area when it comes into contact with the positioning plate 4, thereby increasing the pressure. This can more effectively transfer the pressure to the positioning plate 4, allowing the positioning plate 4 to descend more quickly and accurately. At the same time, it can also ensure the uniformity of pressure transmission and avoid excessive or insufficient local force on the positioning plate 4 due to uneven pressure distribution.

[0044] The time relay 9 is a key component for controlling the working time of the drive component 3. It can precisely control the start and stop time of the drive component 3 according to preset time parameters, thereby controlling the up and down movement time of the pressure block 301 and the descent time of the positioning plate 4, ensuring that the entire welding and pressing process is completed within the specified time. That is, through electrical connection, the time relay 9 can send control signals to the drive component 3 in real time, and control the start, stop and running time of the drive component 3 according to the preset time program. This connection method ensures the precise control of the drive component 3 by the time relay 9, so that the drive component 3 can drive the pressure block 301 and the positioning plate 4 to move according to the set time requirements. The structure of the time relay 9 is well known to those skilled in the art. The key point is to use the time relay 9 to control the drive component 3 to move at an appropriate time. It will not be described in detail in this embodiment.

[0045] Please see Figure 1 and Figure 3 A buffer hole 10 is provided at the top of the base 1, which is located at the position of the positioning plate 4. A buffer rod 11 moves up and down inside the buffer hole 10. The top of the buffer rod 11 abuts against the positioning plate 4. A pressing plate 12 is fixed to the outside of the buffer rod 11. A spring 13 is also sleeved on the outside of the buffer rod 11. The two ends of the spring 13 abut against the pressing plate 12 and the base 1, respectively. An insertion port is provided at the bottom of the positioning plate 4, which is located at the position of the buffer rod 11. The buffer rod 11 is inserted into the insertion port.

[0046] like Figure 1 and Figure 3 As shown, the buffer hole 10 provides a specific space and track for the vertical movement of the positioning plate 4. It limits the range of motion of the positioning plate 4 in the vertical direction, ensuring that the positioning plate 4 can only move up and down along the axis of the buffer hole 10, preventing the positioning plate 4 from deviating or shaking during the movement, and ensuring the straightness and accuracy of its movement.

[0047] The buffer rod 11 serves as a guide and support component for the up-and-down movement of the positioning plate 4. It plays a guiding and stabilizing role during the movement of the positioning plate 4. It can slide smoothly up and down within the buffer hole 10, providing a precise path for the movement of the positioning plate 4. At the same time, it shares part of the weight and external force of the positioning plate 4, reducing friction and resistance during the movement of the positioning plate 4.

[0048] The top of the buffer rod 11 is in direct contact with the positioning plate 4, providing a stable support point for the positioning plate 4. When the positioning plate 4 is subjected to an upward force, the buffer rod 11 can withstand and transmit this force, preventing the positioning plate 4 from moving upward excessively; when the positioning plate 4 is subjected to a downward force, the buffer rod 11 can also play a certain role in buffering and supporting, preventing the positioning plate 4 from falling rapidly and causing impact.

[0049] The pressing plate 12 provides a fixed mounting position and point of application for the subsequent installation of the spring 13. It can be tightly connected to one end of the spring 13, ensuring that the spring 13 can accurately apply force to the buffer rod 11 during compression and extension. At the same time, the pressing plate 12 can also increase the contact area with the spring 13, improving the stability and reliability of the connection. The spring 13 is a key component for realizing the elastic movement of the positioning plate 4. When the positioning plate 4 is subjected to an external force and moves downward, the spring 13 is compressed and stores elastic potential energy. When the external force disappears or decreases, the spring 13 releases the elastic potential energy, pushing the positioning plate 4 upward, so that the positioning plate 4 can automatically return to the initial position or remain in a suitable position. The elastic characteristics of the spring 13 can also play a role in buffering and shock absorption, reducing the impact on the equipment during the movement of the positioning plate 4.

[0050] One end of the spring 13 abuts against the pressing plate 12, and the other end abuts against the base 1, forming a stable mechanical structure. This allows the spring 13 to be compressed and extended evenly when subjected to pressure, accurately exerting its elastic effect. At the same time, this connection method can also prevent the spring 13 from shifting or falling off during operation, ensuring the normal operation of the equipment.

[0051] The socket provides a precise positioning and connection point for the connection between the buffer rod 11 and the positioning plate 4. It ensures that the buffer rod 11 is accurately inserted into the bottom of the positioning plate 4, forming a stable connection structure between the buffer rod 11 and the positioning plate 4. This ensures that the buffer rod 11 can effectively guide and support the up-and-down movement of the positioning plate 4. By inserting the buffer rod 11 into the socket, a mechanical connection is achieved between the buffer rod 11 and the positioning plate 4, enabling them to work together. When the positioning plate 4 is subjected to external force, the buffer rod 11 can accurately transmit the force to the positioning plate 4 through the socket. At the same time, the movement of the positioning plate 4 can also drive the buffer rod 11 to move up and down within the buffer hole 10, jointly completing the up-and-down movement function of the positioning plate 4. Furthermore, when it is necessary to replace different positioning plates 4, they can be directly disassembled and replaced.

[0052] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
