Description

Technical Field

[0001] This utility model relates to the field of mobile communication technology, specifically to a high-efficiency and stable circuit board coupling welding equipment. Background Technology

[0002] With the development of mobile communication technology, the requirements for the stability of base station filters have become higher and the demand has increased significantly. Consequently, the requirements for the stability of related components and the assembly efficiency have also increased to meet production needs.

[0003] In existing technologies, vertically soldering a coupled inductor onto a circuit board requires highly skilled soldering personnel. Furthermore, manual soldering results in deviations in the height and angle of the coupled inductor, leading to extremely low efficiency and an inability to maintain consistency. This reduces product debugging efficiency, and significant deviations can cause rework due to the product failing to meet debugging specifications, resulting in a waste of human and material resources. Utility Model Content

[0004] To address the problems in the background technology, this utility model proposes a highly efficient and stable circuit board coupling welding equipment. This utility model is simple to operate and reduces the skill requirements for welding personnel. It has a high degree of consistency and solves the problems of instability and low efficiency in tooling-less welding.

[0005] To solve the above problems, this utility model adopts the following technical solution: a high-efficiency and stable circuit board coupling welding equipment, including a fixture body, a metal pressure plate and a fixing clamp. The top surface of the fixture body is provided with a square groove for accommodating the PCB board. The bottom surface of the square groove is provided with a groove along its length. Multiple magnets are evenly spaced and embedded in the bottom surface of the groove. Multiple coupling inductors are spaced apart in the groove. The middle part of the multiple coupling inductors is concave and the two ends extend upward to connect with the bottom of the PCB board. The metal pressure plate is pressed into the groove in the middle part of the multiple coupling inductors, and the metal pressure plate is magnetically attracted to the multiple magnets. The fixing clamp is provided on the outside of the square groove on the top surface of the fixture body and is used to fix the PCB board in the square groove.

[0006] Furthermore, the number of fixing clips is at least two, and the at least two fixing clips are arranged on both sides of the top surface of the tooling body, spaced apart from the square groove.

[0007] Furthermore, at least two of the fixing clamps each include a spring rod, a compression spring, and a pressure plate. The spring rod is disposed on the top surface of the fixture body. One end of the pressure plate has a through hole for the spring rod to pass through. The other end of the pressure plate is used to press against the top surface of the PCB board. The compression spring is elastically supported between the upper end of the spring rod and the top surface of the pressure plate.

[0008] Furthermore, the bottom surface of the square groove is provided with positioning pins for mounting and positioning with the PCB board.

[0009] The beneficial effects of this invention are as follows: This invention places multiple coupled inductors to be soldered onto a PCB board into a groove. By placing a metal pressure plate in the groove, the magnetic attraction of multiple magnets on the metal pressure plate presses the middle parts of the multiple coupled inductors firmly into the groove. Simultaneously, the two ends of the multiple coupled inductors extend upwards, allowing the PCB board to be placed into a square slot and fixed with a clamp. The two ends of the multiple coupled inductors extend into the solder joints of the PCB board, achieving stable soldering. Compared to traditional manual soldering, which is prone to height and angle deviations and low efficiency, this invention is simple to operate, has high processing efficiency, and exhibits excellent consistency, thus improving production efficiency and yield.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] This invention places multiple coupled inductors 7, which need to be soldered onto a PCB board, into a groove 5. A metal pressure plate 2 is placed within the groove 5. Due to the magnetic attraction of multiple magnets 6 to the metal pressure plate 2, the middle portions of the multiple coupled inductors 7 are pressed firmly into the groove 5. Simultaneously, the two ends of the multiple coupled inductors 7 extend upwards. The PCB board is placed into a square slot 4 and fixed by a fixing clip 3. The two ends of the multiple coupled inductors 7 extend into the solder joints of the PCB board, achieving stable soldering. Compared to traditional manual soldering, which is prone to height and angle deviations and low efficiency, this invention is simple to operate, has high processing efficiency, and exhibits excellent consistency, thus improving production efficiency and yield.

[0016] Specifically, such as Figure 1 and Figure 2 As shown, a high-efficiency and stable circuit board coupling and soldering equipment includes a fixture body 1, a metal pressure plate 2, and a fixing clamp 3. The top surface of the fixture body 1 has a square groove 4 for accommodating the PCB board. The bottom surface of the square groove 4 has a groove 5 along its length. A plurality of magnets 6 are evenly spaced on the bottom surface of the groove 5. A plurality of coupling inductors 7 are spaced apart in the groove 5. The middle of the plurality of coupling inductors 7 is concave and the two ends extend upward to connect with the bottom of the PCB board. The metal pressure plate 2 is pressed into the groove 5 in the middle of the plurality of coupling inductors 7, and the metal pressure plate 2 is magnetically attracted to the plurality of magnets 6. The fixing clamp 3 is located on the outside of the square groove 4 on the top surface of the fixture body 1 and is used to fix the PCB board in the square groove 4.

[0017] Furthermore, the number of fixing clips 3 is at least two, and at least two fixing clips 3 are arranged on both sides of the top surface of the tooling body 1, spaced apart from the square groove 4.

[0018] Furthermore, at least two of the fixing clamps 3 each include a spring vertical rod 8, a compression spring, and a pressure plate 9. The spring vertical rod 8 is disposed on the top surface of the tooling body 1. One end of the pressure plate 9 has a through hole for the spring vertical rod 8 to pass through, and the other end of the pressure plate 9 is used to press against the top surface of the PCB board. The compression spring is elastically supported between the upper end of the spring vertical rod 8 and the top surface of the pressure plate 9.

[0019] Furthermore, the bottom surface of the square groove 4 is provided with a positioning pin 10 for mounting and positioning with the PCB board.

[0020] In use, this invention involves placing multiple coupled inductors 7, which need to be soldered onto the PCB board, into the groove 5. A metal pressure plate 2 is placed within the groove 5. Due to the magnetic attraction of multiple magnets 6 on the metal pressure plate 2, the middle portions of the multiple coupled inductors 7 are pressed firmly into the groove 5. Simultaneously, the two ends of the multiple coupled inductors 7 extend upwards. The PCB board is then placed into the square groove 4 and fixed using a fixing clip 3. The two ends of the multiple coupled inductors 7 extend into the solder joints of the PCB board for stable soldering. After soldering, the fixing clip 3 is released from the PCB board, and the metal pressure plate 2 is pulled out along the length of the groove 5, allowing the PCB board with the soldered multiple coupled inductors 7 to be easily removed. Compared to traditional manual soldering, which is prone to height and angle deviations and low efficiency, this invention is simple to operate, has high processing efficiency, and exhibits excellent consistency, improving production efficiency and yield.
