Description
Technical Field
[0001] This invention relates to an integrated clamping fixture for inductor pins and substrates in PCBA board soldering assembly, specifically an integrated clamping fixture for inductor pins and substrates in PCBA board soldering assembly, belonging to the field of clamping fixture technology. Background Technology
[0002] PCBA boards are printed circuit boards that have already had their electronic components soldered and assembled. In the electronics manufacturing process, PCBA boards are core components, widely used in various electronic devices such as smartphones, computers, home appliances, and industrial control equipment. Inductors are one of the most common electronic components on PCBA boards, mainly used for filtering, energy storage, and signal processing. Inductors are typically connected to pads on the PCBA board via pins to achieve electrical connections in the circuit. Before PCBA board manufacturing, multiple inductors are assembled onto the substrate and soldered using pins. Therefore, clamping fixtures are needed to hold the substrate and inductors in place to facilitate the normal operation of the soldering process.
[0003] In the prior art, patent announcement number CN216700526U discloses a fixing mold for electronic components, used to fix a PCB board and a guide wire. The mold includes a base and a fixing unit, the fixing unit being detachably connected to the base. The fixing unit includes: a base plate detachably connected to the base and having a PCB groove and a guide wire groove. The PCB groove is used to place the PCB board and partially penetrates the base plate, and the guide wire groove is used for the guide wire to pass through and penetrate the base plate; and a fixing frame detachably connected to the base plate, including a pressing part for pressing the PCB board.
[0004] In the production of electronic products, the soldering and assembly of PCBA boards is a critical process. In traditional soldering processes, inductor components are usually fixed using a single clamping fixture. This fixture is specially designed and can only accommodate inductor components of a specific size and shape. When it is necessary to replace inductor components of different sizes or shapes, or to adjust the position of inductor components, a new, compatible clamping fixture must be manufactured (e.g., injection molding). This single, integrated clamping fixture cannot be flexibly adjusted to accommodate inductor components of different sizes and shapes. Each time a component is replaced, the fixture needs to be remanufactured, increasing production costs and time. Therefore, this reduces the practicality of integrated clamping fixtures for inductor pins and substrates used in PCBA board soldering and assembly. Summary of the Invention

[0021] This invention provides an integrated clamping fixture for inductor pins and substrate for PCBA board soldering assembly.
[0022] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The device includes a device body 1, which includes a substrate placement piece 2 and an inductor placement plate 3 that are rotatably connected to each other. A limiting groove 4 with a linear array distributed grid array is provided on the inner wall of the inductor placement plate 3. An inner groove is formed in the limiting groove 4, and a limiting rod 5 is slidably arranged in the limiting groove 4. A blocking block 6 is fixedly sleeved on the outside of the limiting rod 5, and a spring is slidably sleeved on the outside. Both the blocking block 6 and the spring are located inside the inner groove. Specifically, the end of the limiting rod 5 located on the substrate placement component 2 needs to be wrapped or fitted with a rubber pad. The rubber pad is made of high temperature resistant material to reduce the damage caused by the limiting rod 5 squeezing the inductor. The rubber pad can also deform according to the volume of the inductor, thereby increasing the adaptability of the limiting rod 5. The inner groove has a square cavity cross-section, and the block 6 has a square structure cross-section. The structural design of the block 6 can limit the movement angle of the limiting rod 5, so that the limiting rod 5 cannot rotate. The device body 1 is only used to simultaneously clamp the substrate and the inductor components, forming an integrated clamp, and facilitating subsequent soldering and assembly to form a PCBA board.
[0023] Example 2, please refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 The substrate placement component 2 includes a frame plate 21 and two clamping components 24 arranged in parallel to each other. The frame plate 21 has track grooves 22 on both sides. A bidirectional screw 23 is rotatably connected between the two end faces of the track grooves 22. Two mirror-symmetrical longitudinal sliders 25 are slidably sleeved on the outside of the bidirectional screw 23. The longitudinal sliders 25 are slidably disposed in the track grooves 22. The four longitudinal sliders 25 are respectively fixedly connected to the two ends of the clamping components 24.
[0024] Example 3, please refer to Figure 6 The frame plate 21 has an installation groove that passes through two track grooves 22. A connecting rod 7 is rotatably connected between the two end faces of the installation groove. A bevel gear 8 is fixedly connected to both ends of the connecting rod 7. A bevel gear 9 is fixedly connected to one end of each of the two bidirectional screws 23. The two bevel gears 29 are respectively meshed with the two bevel gears 8. Specifically, the outer side of the bidirectional screw 23 has two mirror-symmetrical external threads, and the two longitudinal sliders 25 of the same group are respectively threaded onto the two external threads of the bidirectional screw 23. To improve the dustproof effect of the bidirectional screw 23, three sets of telescopic corrugated dust covers can be slidably fitted on the outer side of the bidirectional screw 23. The three sets of telescopic corrugated dust covers are respectively set between the two longitudinal sliders 25 and at the opposite ends of the two longitudinal sliders 25. Since the telescopic corrugated dust cover is a publicly disclosed structure, its specific form, usage and installation method are all publicly disclosed technologies, and this application document will not elaborate on them. Among them, the two sets of bidirectional screws 23 need to be mirror-set. This arrangement ensures that the longitudinal sliders 25 of the same row or corresponding on the two sets of bidirectional screws 23 can move in the same direction by using the connecting rod 7. Among them, to improve the rotational synchronization of the two sets of bidirectional screws 23, synchronous bevel gears 9 and 8 can be used. The installation process requires calibration and regular maintenance.
[0025] Example 4, please refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 The clamping member 24 includes a clamping rod 241 and a bidirectional screw 242 arranged parallel to each other. The clamping rod 241 is fixedly connected between two corresponding longitudinal sliders 25, and the bidirectional screw 242 is rotatably connected between two corresponding longitudinal sliders 25. Two L-plates are symmetrically arranged and threaded on the outer side of the bidirectional screw 242. A through transverse groove is opened at the corresponding position of the L-plate relative to the clamping rod 241, and the clamping rod 241 is slidably disposed inside the transverse groove.
[0026] Example 5, please refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 The L-plate includes a dustproof tube 243, a transverse slider 244, a dustproof tube 245, and an L-clamp 246 that are fixedly connected to each other in sequence. The dustproof tube 243, the dustproof tube 245, and the L-clamp 246 are all slidably sleeved on the outside of the double-acting screw 242. The transverse slider 244 is threaded on the outside of the double-acting screw 242. The transverse groove is opened on one side of the L-clamp 246. Specifically, the bidirectional screw 242 includes three long rods and two mirror-symmetrically arranged screws. The two screws are fixedly connected between the three long rods and are offset from the three long rods. The outer diameter of the long rods is larger than the outer diameter of the screws. The transverse slider 244 is threaded onto the outside of the screws. The dustproof tube 1 243, the dustproof tube 245, and the L-clamp 246 are all slidably sleeved on the outside of the long rods. By using the cooperation of the dustproof tube 1 243 and the dustproof tube 245, the screws can be hidden, improving the dustproof effect of the screws.
[0027] Example 6, please refer to Figure 6 and Figure 7 A worm gear 10 is fixedly sleeved on the outer side of the two-way screw 242. A worm 11 is meshed and connected to one side of the worm gear 10. Fixed blocks are rotatably sleeved at both ends of the worm 11. The fixed blocks are fixedly connected to one side of the longitudinal slider 25. A through hexagonal groove is opened at one end of the worm 11. A hexagonal rod 12 is slidably arranged in the hexagonal groove. The hexagonal rod 12 is rotatably connected between the two end faces of the corresponding track groove 22. Specifically, a dust cover needs to be installed on the longitudinal slider 25 to cover the worm gear 11 and worm wheel 10, thereby improving the dustproof effect of the worm gear 11 and worm wheel 10. The dust cover is a publicly available structure, and its specific form, usage and installation method are all existing publicly available technologies, which will not be described in detail in this application. A shaft needs to be fixedly installed at one end of the hexagonal rod 12 and the double-acting screw 23, and a knob is fixedly connected to one end of the shaft. The knob is located on one side of the device body 1 to facilitate the rotation of the hexagonal rod 12 and the double-acting screw 23. A shaft groove needs to be opened at the corresponding position of the device body 1 relative to the shaft, and the shaft is rotatably connected in the shaft groove. In order to increase the stability of the hexagonal rod 12 and the double-acting screw 23, an arc-shaped elastic plate can be set on the inner wall of the shaft groove. The arc-shaped elastic plate squeezes the shaft, increasing the rotational friction and the required force of the shaft. The specific determination depends on the actual needs.
[0028] Example 7, please refer to Figure 1 and Figure 3 The top of the limiting rod 5 is provided with a threaded groove, and a threaded rod 13 is threadedly connected in the threaded groove. A limiting tube 14 is slidably sleeved on the outside of the limiting rod 5. The threaded rod 13 is fixedly connected to the top wall inside the limiting tube 14. The limiting tube 14 is located on the side of the inductor placement plate 3 away from the substrate placement member 2. Specifically, the limiting tube 14 can be rotated according to the position of the limiting rod 5 after the inductor element presses against it, thereby limiting the reset of the limiting rod 5 and facilitating the continued use of the same type of inductor element. A small gap needs to be left between the limiting tube 14 and the inductor placement plate 3 to avoid completely eliminating the restoring ability of the limiting rod 5, thus allowing the limiting rod 5 to press against and fix the inductor element. A nut can be fixedly fitted to the end of the limiting tube 14 away from the limiting rod 5, and a cross groove is opened on the nut to facilitate the rotation of the limiting tube 14 using tools such as a cross wrench. Of course, it can also be rotated manually. When using the device body 1, the position of the limiting tube 14 needs to be adjusted in advance to facilitate subsequent batches of use. The design of the limiting tube 14 will be more troublesome in the initial use because it needs to be adjusted one by one, but only the limiting tube 14 located in the inductor element area needs to be adjusted, thus reducing the workload. In subsequent batches of the same type of use, no adjustment is required. Of course, depending on the actual situation, the limiting rod 5 can be used directly without adjusting the limiting tube 14. The limiting tube 14 can conceal the threaded rod 13, improving the dustproof effect of the threaded rod 13.
[0029] Example 8, please refer to Figure 5 The substrate placement component 2 has two grooves at one corner of the inductor placement plate 3. A magnetic block 15 is installed in the groove 1. The inductor placement plate 3 has two grooves at one corner of the substrate placement component 2. A metal sheet is installed in the groove 2. Specifically, the magnetic block 15 is magnetic and can attract the metal sheet, thereby allowing the substrate placement 2 and the inductor placement plate 3 to be combined and fixed together.
[0030] Example 9, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 A pressing groove is provided on one side of the inductor placement plate 3. A buckle 16 is rotatably connected to the inner wall of the mounting groove. A spring is provided between one end of the buckle 16 and the inner wall of the pressing groove. A lock head is provided at the other end of the buckle 16. The lock head has a vertical triangular cross-section. A slot 17 is provided on one side of the base plate placement piece 2 and at the corresponding position of the lock head. The slot 17 and the lock head on the buckle 16 cooperate with each other. Specifically, the clip 16 can adopt an existing publicly available structure, depending on the actual situation, and is mainly used to quickly fix or lock the mating substrate placement piece 2 and inductor placement plate 3.
[0031] Working principle: First, the substrate is placed on the frame plate 21 of the substrate placement member 2. The four L-shaped clamping rods 246 of the clamping member 24 contact the four corners of the substrate respectively, thereby clamping and fixing the substrate or limiting the position of the substrate. During the adjustment process, the hexagonal rod 12 is manually rotated, which drives the two sets of worm gears 11 to rotate together. The worm gears 11 drive the bidirectional screw 242 to rotate through the worm wheel 10. The bidirectional screw 242 drives the two L-shaped clamping rods 246 of the same set to move closer or further apart, thereby adjusting the position according to the length of the substrate. By rotating one of the bidirectional screws 23, the bidirectional screw 23 drives the connecting rod 7 and the other set of bidirectional screws 23 to circulate together through the cooperation of bevel gear 8 and bevel gear 9. This drives the two sets of clamping members 24 to move closer or further apart, thereby adjusting the position according to the width of the substrate. Insert each inductor pin into the pre-drilled solder holes on the substrate. After placing it stably, rotate the inductor placement plate 3 and merge it with the substrate placement component 2. At this time, the inductor element is located inside the inductor placement plate 3. The corresponding limiting rod 5 is pressed according to the thickness and length of the inductor element, and the limiting rod 5 slides and retracts in the limiting groove 4. At the same time, the stop block 6 compresses the spring. At this time, the limiting tube 14 can be rotated and placed at one end of the inductor placement plate 3 close to the surface wall of the inductor placement plate 3, with a certain gap between them. This can limit the position of the limiting rod 5. The limiting rod 5 can be pressed and fixed by the spring while the position of the limiting rod 5 is limited. Of course, the inductor element can be installed first, and then the substrate can be installed. Then, the substrate placement component 2 can be rotated to merge the substrate placement component 2 and the inductor placement plate 3. The specific method depends on the actual needs. After the substrate and inductor are fixed, the inductor placement plate 3 is combined with the substrate placement piece 2 to align the inductor with the solder points on the substrate. Then, the entire device body 1 is flipped so that the side of the substrate away from the inductor faces upward, making it easier to perform manual or mechanical soldering operations from that side.
[0032] Welding operation: During the welding process, since the substrate and inductor components have been firmly fixed to the device body 1, that is, the tooling, the components will not be displaced during welding, thus ensuring the stability and quality of welding; after welding is completed, flip the tooling, release the clamping part 24 and the limiting rod 5, and the welded PCBA board can be taken out to complete the entire welding assembly process.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
