Description

Technical Field

[0001] This utility model relates to the field of PCB board connector welding technology, specifically to a PCB board connector welding auxiliary positioning device. Background Technology

[0002] PCB connector soldering technology is a core process for achieving electrical connections in electronic manufacturing. It mainly includes reflow soldering, wave soldering, and selective soldering. Reflow soldering achieves high-precision soldering of surface mount components through solder paste printing and four-zone heating, and is suitable for high-density circuit boards. Wave soldering uses a dual-wave system to quickly solder through-hole components, and is suitable for mass production. Selective soldering, as a supplementary process, avoids thermal damage to adjacent components caused by traditional wave soldering through local flux spraying and precise dip soldering. It is especially suitable for mixed assembly scenarios. The soldering quality is significantly affected by the choice of soldering iron tip, temperature control, and flux type. For example, tapered soldering iron tips are suitable for precision components, while chisel-shaped tips are suitable for large-area soldering. Lead-free solder requires a high temperature of 260°C and needs to be designed in conjunction with high-temperature resistant components. Modern processes have also developed through-hole reflow soldering and laser soldering technologies. The former processes through-holes and surface mount components simultaneously, while the latter achieves micron-level precision through non-contact processing to meet the requirements of high-frequency communication equipment.

[0003] However, in the existing technology, when the pin size of the connector is smaller than the PCB hole diameter, the connector is very prone to tilting after being inserted into the PCB, resulting in poor soldering, unstable signal transmission, and affecting the overall performance of the product. Therefore, we need a PCB board connector soldering auxiliary positioning device. Utility Model Content

[0004] The purpose of this utility model is to provide a PCB board connector soldering auxiliary positioning device to solve the existing problems mentioned in the background art, which are that when the pin size of the connector is smaller than the PCB hole diameter, the connector is easily tilted after being inserted into the PCB, resulting in poor soldering, unstable signal transmission, and affecting the overall performance of the product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCB board connector welding auxiliary positioning device, comprising a synthetic stone, an auxiliary component disposed inside the synthetic stone, a positioning component installed inside the synthetic stone, a connector installed inside the auxiliary component, the auxiliary component including a bolt, and the bolt disposed inside the connector, a groove being formed at the bottom of the synthetic stone, and a locking screw being disposed inside the synthetic stone.

[0006] Preferably, the synthetic stone forms a locking structure with the connector through a groove, and the inner diameter of the groove matches the outer diameter of the connector, and the inner wall of the groove fits snugly against the outer wall of the connector.

[0007] Preferably, the synthetic stone has multiple locking screws, and the multiple locking screws are evenly spaced inside the synthetic stone.

[0008] Preferably, the positioning component includes a positioning block disposed inside the synthetic stone. A fixing rod is hinged to one side of the positioning block, and a first sliding sleeve is hinged inside the fixing rod. A positioning rod is hinged to one side of the positioning block, and a second sliding sleeve is hinged inside the positioning rod. A spring is fixedly connected to one side of the second sliding sleeve, and a fixing post is movably connected to the inner wall of the second sliding sleeve. A positioning groove is provided on one side of the connector.

[0009] Preferably, the first sliding sleeve and the second sliding sleeve form a fixed structure by means of a spring, and the spring is disposed between the first sliding sleeve and the second sliding sleeve.

[0010] Preferably, the first sliding sleeve forms a linkage structure with the positioning block through the fixing rod, and the inside of the fixing rod is hinged to the outer wall of the first sliding sleeve, and the inside of the fixing rod is hinged to one side of the positioning block.

[0011] Preferably, the positioning rod forms a sliding structure with the fixed column through the second sliding sleeve, and the inside of the positioning rod is hinged to the outer wall of the second sliding sleeve, and the inner diameter of the second sliding sleeve matches the outer diameter of the fixed column, and the inner wall of the second sliding sleeve is fitted to the outer wall of the fixed column.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In the scheme of this application: 1. To address the problem in existing technologies where connector pin sizes are smaller than PCB hole diameters, connectors are prone to tilting after insertion into the PCB, leading to weak soldering, unstable signal transmission, and impacting overall product performance, this application addresses this issue by implementing a bolt-fixing structure between a synthetic stone and the PCB. The finely milled surface of the synthetic stone serves as a reliable reference, ensuring the connector and PCB remain precisely perpendicular at 90 degrees, effectively preventing tilting. Simultaneously, rotating the locking screws allows for precise adjustment of the soldering surfaces of multiple connectors, ensuring they are on the same horizontal plane. This achieves a 90-degree angle between the connector and PCB, with the connector soldering surfaces on the same horizontal plane, guaranteeing high-quality reflow soldering. 2. To address the problems of inaccurate positioning, cumbersome operation, and connector misalignment during positioning in existing PCB connector welding auxiliary positioning devices, which lead to welding position deviations and affect welding quality, this application proposes a linkage positioning structure comprising a positioning block, a fixing rod, a positioning rod, a sliding sleeve, and a spring. When the connector is moved to engage with the groove on the synthetic stone, the connector presses against the positioning block, causing the fixing rod and positioning rod to move. This, in turn, pushes the sliding sleeve to slide on the outer wall of the fixing post and stretches the spring. When the connector reaches the positioning groove, the spring resets, causing all components to move in the opposite direction, ensuring precise engagement between the positioning block and the positioning groove. This achieves rapid and accurate positioning of the connector, guaranteeing welding quality. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a PCB board connector soldering auxiliary positioning device, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a synthetic stone 1 has an auxiliary component 2 and an internal mounting and positioning component 3. A connector 4 is installed inside the auxiliary component 2. The auxiliary component 2 includes bolts 201, which are located inside the connector 4. A groove 202 is provided on the bottom of the synthetic stone 1. A locking screw 203 is provided inside the synthetic stone 1. By rotating the two bolts 201, the synthetic stone 1 is fixed to the PCB board. The milled side of the synthetic stone 1 ensures that the connector 4 and the PCB board are at a 90-degree angle. Then, by rotating the locking screw 203, the welding surfaces of the three connectors 4 are kept on the same horizontal plane, thereby completing the auxiliary process of reflow soldering the connectors 4.

[0017] Further such as Figure 2 and Figure 3 As shown, the synthetic stone 1 and the connector 4 form a locking structure through the groove 202, and the inner diameter of the groove 202 matches the outer diameter of the connector 4. The inner wall of the groove 202 fits against the outer wall of the connector 4. Through the groove 202, the connector 4 can lock into the groove 202 on the synthetic stone 1, effectively preventing relative movement between the two, enhancing connection stability, ensuring reliable operation of the overall structure during use, reducing the risk of loosening and failure, and facilitating the welding of the connector 4.

[0018] Further such as Figure 1 and Figure 2 As shown, there are multiple locking screws 203 on the synthetic stone 1, and the multiple locking screws 203 are evenly spaced inside the synthetic stone 1. The locking screws 203 can rotate under the support of the synthetic stone 1. The locking screws 203 make the three connectors 4 on the same horizontal plane, ensuring that the position of each connector 4 is accurate and the force is even, improving the overall assembly quality and stability, ensuring the normal operation of the equipment, and facilitating the welding of the connectors 4.

[0019] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the positioning component 3 includes a positioning block 301, which is disposed inside the synthetic stone 1. A fixing rod 302 is hinged to one side of the positioning block 301, and a first sliding sleeve 303 is hinged inside the fixing rod 302. A positioning rod 304 is hinged to one side of the positioning block 301, and a second sliding sleeve 305 is hinged inside the positioning rod 304. A spring 306 is fixedly connected to one side of the second sliding sleeve 305, and a fixing post 307 is movably connected to the inner wall of the second sliding sleeve 305. A positioning groove 308 is provided on one side of the connector 4. By moving the connector 4, the connector 4 engages with the groove 202 on the synthetic stone 1. During the engagement process, the connector 4 presses the positioning block 301, causing the positioning block 301 to... The moving fixed rod 302 and positioning rod 304 move, causing the fixed rod 302 and positioning rod 304 to push the first sliding sleeve 303 and the second sliding sleeve 305 to slide on the outer wall of the fixed post 307. This causes the first sliding sleeve 303 and the second sliding sleeve 305 to stretch the spring 306. When the spring 306 reaches the positioning groove 308 on the connector 4, it resets and causes the spring 306 to drive the first sliding sleeve 303 and the second sliding sleeve 305 to move. This causes the first sliding sleeve 303 and the second sliding sleeve 305 to drive the fixed rod 302 and the positioning rod 304 to move. This causes the fixed rod 302 and the positioning rod 304 to drive the positioning block 301 to move, so that the positioning block 301 engages with the positioning groove 308, thereby completing the positioning of the connector 4.

[0020] Further such as Figure 4 As shown, the first sliding sleeve 303 and the second sliding sleeve 305 form a fixed structure through the spring 306, and the spring 306 is disposed between the first sliding sleeve 303 and the second sliding sleeve 305. Through the disposed spring 306, the spring 306 can be fixed to the second sliding sleeve 305 under the support of the first sliding sleeve 303, which facilitates the elastic deformation of the spring 306 under the action of the first sliding sleeve 303 and the second sliding sleeve 305, which is beneficial for positioning the connector 4.

[0021] Further such as Figure 4 As shown, the first sliding sleeve 303 forms a linkage structure with the positioning block 301 through the fixing rod 302. The inside of the fixing rod 302 is hinged to the outer wall of the first sliding sleeve 303, and the inside of the fixing rod 302 is hinged to one side of the positioning block 301. Through the setting of the fixing rod 302, the fixing rod 302 can push the first sliding sleeve 303 to move under the drive of the positioning block 301, realizing the linkage control between components. The position of the first sliding sleeve 303 can be adjusted as needed, thereby flexibly changing the relevant structural state to meet the needs of different working conditions, ensuring the accuracy and adaptability of equipment operation, and facilitating the positioning of the connector 4.

[0022] Further such as Figure 4As shown, the positioning rod 304 forms a sliding structure with the fixed post 307 via the second sliding sleeve 305. The inside of the positioning rod 304 is hinged to the outer wall of the second sliding sleeve 305, and the inner diameter of the second sliding sleeve 305 matches the outer diameter of the fixed post 307. The inner wall of the second sliding sleeve 305 is fitted against the outer wall of the fixed post 307. With the second sliding sleeve 305, the positioning rod 304 can push the second sliding sleeve 305, causing the second sliding sleeve 305 to slide on the outer wall of the fixed post 307. This achieves coordinated operation between mechanical components, ensures stable equipment operation, improves the overall accuracy and reliability of the work, and is beneficial for positioning the connector 4.

[0023] Working principle: In use, first mill the side of the synthetic stone 1 that contacts the PBC board flat. When it is necessary to position the connector 4, move the connector 4 so that it engages with the groove 202 on the synthetic stone 1. During engagement, the connector 4 presses against the positioning block 301, causing the positioning block 301 to move the fixing rod 302 and the positioning rod 304. This causes the fixing rod 302 and the positioning rod 304 to push the first sliding sleeve 303 and the second sliding sleeve 305 to slide on the outer wall of the fixing post 307. This causes the first sliding sleeve 303 and the second sliding sleeve 305 to stretch the spring 306. When they reach the positioning groove 308 on the connector 4, the spring 306 returns to its original position, causing the spring 306 to move the first sliding sleeve 303 and the second sliding sleeve 305 to engage the groove 202 on the synthetic stone 1. The second sliding sleeve 305 moves, causing the first sliding sleeve 303 and the second sliding sleeve 305 to move the fixing rod 302 and the positioning rod 304. This causes the fixing rod 302 and the positioning rod 304 to move the positioning block 301, which engages with the positioning groove 308, thus completing the positioning of the connector 4. When it is necessary to assist the connector 4 in reflow soldering, the synthetic stone 1 can be fixed to the PCB board by rotating the two bolts 201. The milled side of the synthetic stone 1 ensures that the connector 4 and the PCB board are at a 90-degree angle. Then, the locking screw 203 is rotated so that the locking screw 203 keeps the soldering surfaces of the three connectors 4 on the same horizontal plane, thus completing the assistance for reflow soldering the connector 4.
