Description

Technical Field

[0001] This utility model relates to the field of soldering equipment technology, specifically a soldering equipment for transformer coils. Background Technology

[0002] High-frequency transformers are power transformers with operating frequencies exceeding intermediate frequencies. Their working principle is that when an alternating current flows through the primary coil, an alternating magnetic flux is generated in the iron core or magnetic core, inducing a voltage or current in the secondary coil. In the production process of high-frequency transformers, the soldering process of the leads is essential. Currently, most lead soldering is done with a simple soldering head and solder wire, which is very simple to operate and can basically meet the current production needs.

[0003] Patent CN210334663U proposes a pin soldering device for high-frequency transformers. It is controlled by a threaded rod and an electric telescopic rod, avoiding hand-held control and making the control more stable. It also has multiple soldering heads, which can solder multiple soldering points at the same time. The distance between each soldering head is also adjustable, making it more widely applicable.

[0004] The shortcomings of the above solution are: existing coils generally have multiple pins that need to be soldered to multiple connecting wires of electronic devices. During this process, the pins and connecting wires are prone to misalignment, leading to soldering failure. Fixing the pins during the soldering process will affect the overall efficiency of the soldering. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a soldering device for transformer coils to solve the problems mentioned in the background. This invention features a novel structure. It clamps and fixes the coil and electronic components through an installation assembly. With the cooperation of a wire harness frame and a buckle plate, the coil leads and connecting wires are pulled and straightened, allowing for accurate docking. Furthermore, it prevents misalignment during the soldering process, ensuring soldering accuracy. The turntable processing method effectively improves soldering efficiency.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a soldering device for transformer coils, comprising a base, a drive motor fixed to the top of the base, and a turntable fixed to the output end of the drive motor. The top of the turntable is provided with four sets of mounting components, each mounting component including a base plate. Two first clamping blocks are symmetrically arranged at one end of the base plate near the center of the turntable, and two second clamping blocks are symmetrically arranged at the other end of the base plate. A coil assembly is clamped and fixed between the two first clamping blocks, and an electronic component is clamped and fixed between the two second clamping blocks. The pins of the coil assembly and the connecting wires of the electronic components are connected to the top of the base plate. A wire harness frame is provided at the bottom of the base plate corresponding to the pins of the coil assembly and the connecting wires of the electronic components, and the pins of the coil assembly and the connecting wires of the electronic components pass through the wire harness frame. An electric push rod is fixed to one side of the base, and a top plate is fixed to the top of the electric push rod. A soldering component is fixed to the end of the top plate near the connector of the pins of the coil assembly and the connecting wires of the electronic components.

[0007] Furthermore, the mounting assembly also includes a first sliding groove, the top of the base plate having a first sliding groove corresponding to the position of the first clamping block, and the bottom of the first clamping block sliding along the first sliding groove; the top of the base plate having two second sliding grooves corresponding to the position of the bottom of the second clamping block, and the bottom of the second clamping block sliding along the second sliding grooves.

[0008] Furthermore, a connecting plate is fixed to the outer side of the second clamping block, and a bolt is threaded into one end of the connecting plate. A screw hole is opened on the outer side of the first clamping block, and the bolt is threaded into the outer surface of the first clamping block.

[0009] Furthermore, a first bidirectional screw is rotatably mounted inside the first groove via a bearing, and the bottom of the first clamping block is threaded onto the surface of the first bidirectional screw.

[0010] Furthermore, a vertical plate is fixed to the bottom of the wire harness frame, and hollow slots are provided on both sides of the vertical plate. A vertical frame is slidably connected to both sides of the vertical plate. A spring is built into the hollow slot and connected to the vertical frame. A buckle plate is fixed to the top of the vertical frame, and the buckle plate is pressed and covered on the top of the pin and the connecting wire.

[0011] Furthermore, a third sliding groove is provided on the surface of the base plate corresponding to the two vertical plates, and the vertical plates slide along the inside of the third sliding groove. A second bidirectional screw is rotatably installed in the third sliding groove through a bearing, and the bottom of the vertical plate is threaded onto the surface of the second bidirectional screw.

[0012] Furthermore, one end of the second bidirectional screw extends through the base plate and is fixed with a shaft, and a transmission belt is mounted on the surface of the shaft. The pulley at the other end of the transmission belt is connected to the first bidirectional screw of another set of mounting components.

[0013] Furthermore, inclined plates are fixed on both sides of the bottom of the base plate corresponding to the bottom of the vertical plate, and rollers are rotatably installed on the bottom of the vertical frame along the inclined surface of the inclined plates, and the rollers slide along the inclined surface of the inclined plates.

[0014] The beneficial effects of this utility model are:

[0015] When the second bidirectional screw rotates, the wire harness frame moves horizontally along the third slide groove with the vertical plate. During this process, as the inclined plate descends and the spring force in the hollow grooves on both sides of the vertical plate increases, the vertical frame moves downward and the buckle plate gradually presses against the top of the wire harness frame. In this process, the pins of the coil assembly and the connecting wires of the electronic components are straightened and clamped and fixed after docking to maintain the stability after docking.

[0016] This invention uses a shaft to drive a transmission belt, causing the first bidirectional screw of the next set to rotate. The first and second clamping blocks of the next set of mounting components clamp and fix the coil assembly and electronic components respectively, thereby improving the efficiency of subsequent soldering.

[0017] This invention adjusts the initial distance between the first clamping block and the second clamping block using bolts, and locks the first clamping block and the second clamping block together using a connecting plate. Thus, the two clamping blocks can clamp the coil assembly and the electronic component respectively under the drive of the first bidirectional screw. Furthermore, the initial position of the bolts can be adjusted according to the size of the coil or the size difference between the coil assembly and the electronic component, so that the first clamping block and the second clamping block can clamp the two components simultaneously.

[0018] Compared with the prior art, this utility model clamps and fixes the coil and electronic components through the installation components. With the cooperation of the wire harness frame and the buckle plate, the coil pins and connecting wires are pulled and straightened so that the two can be accurately connected and will not be misaligned during the welding process, thus ensuring the accuracy of welding. The turntable processing method can effectively improve the efficiency of soldering. Attached Figure Description

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Please see Figures 1 to 7This utility model provides a technical solution: a soldering device for transformer coils, including a base 1, a drive motor 12 fixed to the top of the base 1, and a turntable 11 fixed to the output end of the drive motor 12. The top of the turntable 11 is provided with four sets of mounting components 3. Each mounting component 3 includes a base plate 31. Two first clamping blocks 35 are symmetrically arranged at one end of the base plate 31 near the center of the turntable 11, and two second clamping blocks 39 are symmetrically arranged at the other end of the base plate 31. A coil assembly 36 is clamped and fixed between the two first clamping blocks 35, and an electronic component 311 is clamped and fixed between the two second clamping blocks 39. The pins of the coil assembly 36 and the connecting wires of the electronic component 311 are connected to the top of the base plate 31. A wire harness frame 312 is provided at the bottom of the base plate 31 corresponding to the connecting wires of the coil assembly 36 and the electronic component 311. The connecting wire of component 311 passes through the wire harness frame 312. An electric push rod 2 is fixed on one side of the base 1, and a top plate 21 is fixed on the top of the electric push rod 2. A soldering assembly 22 is fixed on one end of the top plate 21 near the pin of the coil assembly 36 and the connector of the connecting wire of electronic component 311. When using the device, the coil assembly 36 and electronic component 311 are placed on the base plate 31 respectively and clamped and fixed by the first clamping block 35 and the second clamping block 39. Then, the drive motor 12 drives the turntable 11 to rotate, rotating the coil assembly 36 and electronic component 311 to the bottom of the soldering assembly 22. The mounting assembly 3 pulls and straightens the pin of the coil assembly 36 and the connecting wire of the electronic component 311 to connect. Then, the electric push rod 2 drives the soldering assembly 22 to move vertically and solder near the connection position of the two. After the soldering is completed, the turntable 11 rotates to continue the soldering process of the next group.

[0029] In this embodiment, the mounting assembly 3 further includes a first sliding groove 34. The top of the base plate 31 has a first sliding groove 34 corresponding to the position of the first clamping block 35, and the bottom of the first clamping block 35 slides along the first sliding groove 34. The top of the base plate 31 has two second sliding grooves 310 corresponding to the position of the bottom of the second clamping block 39, and the bottom of the second clamping block 39 slides along the second sliding grooves 310. A connecting plate 37 is fixed to the outer side of the second clamping block 39, and a bolt 38 is threaded into one end of the connecting plate 37. A screw hole is provided on the outer side of the first clamping block 35, and the screw... Bolt 38 is threaded into the outer surface of the first clamping block 35. The initial distance between the first clamping block 35 and the second clamping block 39 is adjusted by bolt 38, and the first clamping block 35 and the second clamping block 39 are locked together by connecting plate 37. Thus, the two can clamp the coil assembly 36 and the electronic component 311 respectively under the drive of the first bidirectional screw 32. The initial position of bolt 38 can be adjusted according to the size of the coil or the size difference between the coil assembly 36 and the electronic component 311, so that the first clamping block 35 and the second clamping block 39 can clamp the two components at the same time.

[0030] In this embodiment, a vertical plate 317 is fixed to the bottom of the wire harness frame 312, and hollow slots are provided on both sides of the vertical plate 317. A vertical frame 318 is slidably connected to both sides of the vertical plate 317. A spring is built into the hollow slot and connected to the vertical frame 318. A buckle plate 313 is fixed to the top of the vertical frame 318. The buckle plate 313 presses and covers the top of the pins and connecting wires. A third sliding groove 315 is provided on the surface of the bottom plate 31 corresponding to the two vertical plates 317, and the vertical plate 317 slides along the inside of the third sliding groove 315. A second bidirectional screw is rotatably installed in the third sliding groove 315 through a bearing. A rod 316 is attached, and the bottom of the vertical plate 317 is threaded onto the surface of the second bidirectional screw 316. An inclined plate 314 is fixed to both sides of the bottom of the vertical plate 317 on the base plate 31. A roller 319 is rotatably mounted on the bottom of the vertical frame 318 along the inclined surface of the inclined plate 314. The roller 319 slides along the inclined surface of the inclined plate 314. A first bidirectional screw 32 is rotatably mounted inside the first groove 34 via a bearing. The bottom of the first clamping block 35 is threaded onto the surface of the first bidirectional screw 32. One end of the second bidirectional screw 316 extends out of the base plate 31 and is fixed to a shaft 33. A transmission belt 320 is mounted on the surface of the 33. The pulley at the other end of the transmission belt 320 is connected to the first bidirectional screw 32 of another set of mounting components 3. A small motor is built into the base plate 31 at the position corresponding to the other end of the second bidirectional screw 316, which can drive the second bidirectional screw 316 to rotate. It is only activated when the base plate 31 rotates to the bottom of the soldering component 22 to provide power to the transmission belt 320. The function is that when the second bidirectional screw 316 rotates, the wire harness frame 312 moves horizontally along the third slide groove 315 with the vertical plate 317. During this process, the inclined plate 314 moves downward. The spring force in the slots on both sides of the vertical plate 317 causes the vertical frame 318 to move downward, and the buckle plate 313 gradually presses against the top of the wire harness frame 312. During this process, the pins of the coil assembly 36 and the connecting wires of the electronic component 311 are straightened and clamped and fixed after docking to maintain stability after docking. At the same time, the shaft 33 drives the transmission belt 320 to rotate, so that the first bidirectional screw 32 of the next set rotates. The first clamping block 35 and the second clamping block 39 of the next set of mounting components 3 clamp and fix the coil assembly 36 and the electronic component 311 respectively, thereby improving the efficiency of subsequent soldering.

[0031] When using the device, the coil assembly 36 and electronic component 311 are placed on the base plate 31 and clamped and fixed by the first clamp 35 and the second clamp 39. Then, the drive motor 12 drives the turntable 11 to rotate, rotating the coil assembly 36 and electronic component 311 to the bottom of the soldering assembly 22. A small motor is built into the base plate 31 at the other end of the second bidirectional screw 316, which can drive the second bidirectional screw 316 to rotate. It is only activated when the base plate 31 rotates to the bottom of the soldering assembly 22 to provide power to the transmission belt 320. The function of this is that when the second bidirectional screw 316 rotates, the wire harness frame 312 moves along the third slide along the vertical plate 317. As slot 315 moves horizontally, the vertical frame 318 moves downward due to the descent of the inclined plate 314 and the spring force in the hollowed-out slots on both sides of the vertical plate 317. The buckle plate 313 gradually presses against the top of the wire harness frame 312. During this process, the pins of the coil assembly 36 and the connecting wires of the electronic component 311 are straightened and clamped and fixed after docking to maintain stability after docking. At the same time, the shaft 33 drives the transmission belt 320 to rotate, causing the first bidirectional screw 32 of the next group to rotate. The first clamping block 35 and the second clamping block 39 of the next group of mounting components 3 clamp and fix the coil assembly 36 and the electronic component 311 respectively, thereby improving the efficiency of subsequent soldering.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
