Description

Technical Field

[0001] This utility model belongs to the field of circuit board tooling technology, and particularly relates to a tooling structure for circuit boards. Background Technology

[0002] During the filter manufacturing process, the PCB board of the active part of the filter needs to be soldered to the pins and then assembled into the corresponding holes on the product. The pins and the corresponding openings on the product must correspond one-to-one. When the main pin in the first PCB assembly (the PCB with multiple pins) is soldered crookedly, it cannot be inserted into the corresponding product hole, affecting the assembly. Currently, the main pin is prone to crookedness when soldering the circuit board to the main pin, and during the soldering process on the front side of the circuit board, solder tends to flow to the area around the main pin on the back side of the circuit board. This can easily lead to short circuits when the circuit board and the pin assembly are assembled into the product. Utility Model Content

[0006] Furthermore, each set of elastic components includes: an elastic element, a positioning rod, and an adjusting nut; one end of the positioning rod passes through the insertion hole and is threadedly connected to the adjusting nut, and the other end of the positioning rod protrudes outward to form a boss that abuts against the end of the pin; the elastic element is disposed between the insertion hole and the boss to stabilize the height of the pin between the upper pressure plate and the retaining seat.

[0007] Furthermore, the inner diameter of each of the plug holes on the side closer to the support is larger than the inner diameter of the corresponding plug hole on the side farther from the support.

[0008] Furthermore, each of the said insertion holes is coaxial with the corresponding said insertion pin.

[0009] Furthermore, the upper pressure plate is provided with a first groove and a second groove on the side opposite to the limiting groove.

[0018] Figure 1This is a schematic diagram of a tooling structure for a circuit board according to an embodiment of the present utility model. Figure 2 This is an exploded structural diagram of a tooling structure for a circuit board according to an embodiment of the present invention.

[0019] Reference Figure 1 According to an embodiment of the present invention, a tooling structure for a circuit board 4 includes: an upper pressure plate 1, a supporting seat 2, a base 3, a circuit board 4, multiple magnetic components 5, multiple sets of elastic components 6, and multiple pins 7. The upper pressure plate 1 has a recessed surface forming a limiting groove 11, and the upper pressure plate 1 and the supporting seat 2 are magnetically connected to limit the entire circuit board 4 within the limiting groove 11. (See reference...) Figure 2 The surface of the support seat 2 has a raised protrusion forming a first positioning post 21 perpendicular to the surface of the support seat 2. Magnetic elements 5 are respectively installed on both sides of the support seat 2. Multiple pins 7 are vertically fixed on the surface of the circuit board 4, and the circuit board 4 is fixed above the support seat 2 by the first positioning post 21. The base 3 and the support seat 2 are connected by an insertion to stabilize the position of the support seat 2 between the upper pressure plate 1 and the base 3. The base 3 has multiple insertion holes 31 that match the elastic components 6, and each insertion hole 31 is fitted with a set of elastic components 6. The end of each set of elastic components 6 and the corresponding pin 7 are stabilized on the limiting post by the elastic force, thereby clamping and fixing the entire circuit board 4 between the upper pressure plate 1 and the support seat 2, so as to facilitate soldering and fixing of the circuit board 4.

[0020] Continue to refer to Figure 2 Specifically, each set of elastic components 6 includes: an elastic element 61, a positioning rod 62, and an adjusting nut 63. The elastic element 61 is housed within the insertion hole 31. One end of the positioning rod 62 extends through the insertion hole 31 and is threadedly connected to the adjusting nut 63. The other end of the positioning rod 62 protrudes outward, forming a boss 621. The elastic element 61 is positioned between the insertion hole 31 and the boss 621. The end face of the boss 621 abuts against the end face of the corresponding pin 7, thereby stabilizing the height of the pin 7 between the upper pressure plate 1 and the retaining seat 2.

[0021] Furthermore, the protrusions on the surface of the base 3 form multiple second limiting posts 32 for limiting the support seat 2. Each second limiting post 32 is distributed along the outer periphery of the base 3 and is perpendicular to the surface of the base 3. Each insertion hole 31 is located inside the area enclosed by each second limiting post 32. After each second limiting post 32 is inserted into the support seat 2, the support seat 2 and the base 3 form an integral structure. The support seat 2 is magnetically connected to the upper pressure plate 1, thereby forming a stable structure among the upper pressure plate 1, the support seat 2, and the base 3.

[0022] Furthermore, the diameter of the insertion hole 31 on the surface of the base 3 is larger on the side closer to the support seat 2 than on the side farther away from the support seat 2. When the elastic component 6 is placed, one end of the elastic element 61 abuts against the lower end of the boss 621, and the other end of the elastic element 61 abuts against the end of the insertion hole 31, thereby being confined within the insertion hole 31.

[0023] Furthermore, the surface of the upper pressure plate 1 is also provided with a first groove 12 and a second groove 13 opposite to the limiting groove 11. The first groove 12 and the limiting groove 11 are symmetrically arranged about the second groove 13. The first groove 12 is located on the outer periphery of the second groove 13, and the area of ​​the first groove 12 is larger than the area of ​​the second groove 13. The area of ​​the limiting groove 11 is equal to the area of ​​the first limiting groove 11. Preferably, the first groove 12 is connected to the limiting groove 11 through the second groove 13, and the groove depths of the first groove 12, the second groove 13, and the limiting groove 11 are all equal.

[0024] Figure 3 This is another exploded structural diagram of a tooling structure for a circuit board according to an embodiment of the present utility model.

[0025] Refer to together Figure 2 and Figure 3 Specifically, the surface of the retaining seat 2 is provided with multiple positioning holes 22 that match the pins 7. Each positioning hole 22 is coaxially arranged with one of the insertion holes 31, and the diameter of each positioning hole 22 is smaller than the diameter of the insertion hole 31. Magnetic suction holes 23 are provided on both sides of the retaining seat 2, and a corresponding magnetic element 5 is placed in each magnetic suction hole 23. The outer periphery of the array formed by the positioning holes 22 is also provided with mounting holes that match the second positioning post 32. In this embodiment, the magnetic element 5 is a magnet or magnetic bead, or other magnetic material. Furthermore, in this embodiment, the elastic element 61 is a spring of various types. When the pin 7 passes through the positioning hole 22, the end of the pin 7 abuts against the end face of the boss 621. After the adjusting nut 63 is installed at the end of the positioning rod 62, the elastic force generated by the compression of the elastic element 61 keeps the pin 7 in a stable position.

[0026] At this time, the first positioning post 21 passes through the circuit board 4 to position the circuit board 4, and the elastic component 6 stabilizes the position of the pin 7 so that the circuit board 4 can be soldered at the connection point with the pin 7 on the front side. In this embodiment, the second groove 13 serves as the inlet for the soldering equipment and the observation port during soldering.

[0027] In summary, this utility model enables the circuit board to be stably soldered during the main rod process through the magnetic connection between the upper pressure plate and the holding seat, thereby avoiding product failure caused by solder overflow due to the misalignment of the main rod.
