[0043] As described in the background section, during circuit board manufacturing, electronic components or assemblies need to be fixed onto the circuit board using soldering technology to achieve electrical connections. During the soldering operation, tooling is required to hold the circuit board in place. However, existing tooling provides poor fixation for circuit boards, resulting in low soldering accuracy and efficiency. Furthermore, due to the different specifications of circuit boards, multiple toolings are required for adaptation, which also leads to low soldering efficiency and increased production costs.
[0044] Based on this, please refer to Figures 1-4 The present invention provides a circuit board welding and fixing fixture 100, which can effectively improve the technical problems mentioned above. That is, it can improve the welding and fixing effect of the circuit board 200, and can be adapted to circuit boards 200 of various specifications, thereby improving welding efficiency and accuracy and reducing production costs.
[0045] It should be noted that the first direction mentioned below refers to... Figure 1 and Figure 2 The X direction is shown in the figure, and the second direction is... Figure 1 and Figure 2 The Y direction shown in the figure, the third direction is Figure 1 and Figure 2 The Z direction is shown in the figure. The following will provide a detailed description of the circuit board soldering fixture 100.
[0046] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the circuit board welding and fixing fixture 100 provided in this embodiment. Figure 2 This is an assembly diagram of the circuit board soldering fixture 100 and the circuit board 200 provided in this embodiment, in conjunction with... Figure 1 and Figure 2The circuit board welding fixture 100 includes a fixture plate 10, a fixing component 20, a clamping component 30, and an adjusting component 40. The fixing component 20 is disposed on the fixture plate 10. The clamping component 30 includes a first clamping block 31, a second clamping block 32, and a third clamping block 33. The first clamping block 31 and the second clamping block 32 are spaced apart along a first direction and are slidably disposed on the fixing component 20 along the first direction. The third clamping block 33 is spaced apart from the first clamping block 31 and the second clamping block 32 along a second direction and is slidably disposed on the fixing component 20 along the second direction. 0; The adjusting component 40 is slidably disposed on the fixing component 20 along the second direction and is located on the side of the third clamping block 33 away from the first clamping block 31 and the second clamping block 32; wherein the first clamping block 31 and the second clamping block 32 are both used to clamp one side of the circuit board 200, the third clamping block 33 is used to clamp the opposite side of the circuit board 200, and the adjusting component 40 is used to abut against the third clamping block 33 so that the third clamping block 33 cooperates with the first clamping block 31 and the second clamping block 32 to clamp and fix the circuit board 200; the first direction and the second direction form an angle.
[0047] By sliding the first clamping block 31 and the second clamping block 32 back and forth on the fixing component 20, circuit boards 200 of different lengths or widths can be adapted to clamp one side of them; and by sliding the third clamping block 33 back and forth on the fixing component 20, circuit boards 200 of different widths or lengths can be adapted to clamp the opposite side of them, thereby achieving adaptive clamping and fixing of circuit boards 200 of various specifications. At the same time, the third clamping block 33 is abutted by the adjusting component 40 and cooperates with the first clamping block 31 and the second clamping block 32, so that the three form a triangular structure, thereby achieving a stable clamping of the circuit board 200. In other words, the circuit board welding fixing fixture 100 has strong versatility and good welding fixing effect, eliminating the need to use multiple fixtures to fix circuit boards 200 of different specifications separately, reducing production costs, and improving welding efficiency and accuracy.
[0048] Specifically, the fixing component 20 includes a first fixing block 21, a second fixing block 22, a first slide rod 23, a second slide rod 24, and a third slide rod 25. The first fixing block 21 and the second fixing block 22 are spaced apart on the tooling plate 10 along a second direction. The first slide rod 23 and the second slide rod 24 are respectively disposed on both sides of the first fixing block 21 along a first direction. The first clamping block 31 is slidably disposed on the first slide rod 23, and the second clamping block 32 is slidably disposed on the second slide rod 24. The two ends of the third slide rod 25 are respectively connected to the first fixing block 21 and the second fixing block 22. The third clamping block 33 and the adjusting component 40 are slidably disposed on the third slide rod 25, and the adjusting component 40 is located between the third clamping block 33 and the second fixing block 22.
[0049] Combination Figure 1As is easily understood, the first clamping block 31 slides back and forth on the first slide bar 23, and the second clamping block 32 slides back and forth on the second slide bar 24, allowing the first clamping block 31 and the second clamping block 32 to move closer to or further away from each other; while the third clamping block 33 slides back and forth on the third slide bar 25, allowing it to move closer to or further away from the first clamping block 31 and the second clamping block 32. Thus, when the first clamping block 31 and the second clamping block 32 are used to clamp circuit boards 200 of different lengths, the corresponding third clamping block 33 is used to clamp circuit boards 200 of different widths; conversely, when the first clamping block 31 and the second clamping block 32 are used to clamp circuit boards 200 of different widths, the corresponding third clamping block 33 is used to clamp circuit boards 200 of different lengths.
[0050] It should be noted that, in this embodiment, the first clamping block 31 is specifically sleeved on the first slide rod 23, the second clamping block 32 is specifically sleeved on the second slide rod 24, and the third clamping block 33 is specifically sleeved on the third slide rod 25. This sleeved arrangement improves sliding stability and clamping stability of the circuit board 200. Of course, in other embodiments, the clamping blocks and slide rods can also achieve sliding cooperation through grooves and rails.
[0051] In addition, it should be noted that the first slide bar 23, the second slide bar 24, and the third slide bar 25 are all spaced apart from the tooling plate 10 along a third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other. This spaced arrangement can prevent the first clamping block 31, the second clamping block 32, and the third clamping block 33 from interfering with the tooling plate 10 during the sliding process, thereby improving the smoothness of the sliding.
[0052] Please continue to combine Figure 1 and Figure 2 Specifically, the adjustment assembly 40 includes a slider 41, an elastic element 42, and an adjustment element 43. The slider 41 is slidably disposed on the third slide rod 25, the elastic element 42 is disposed on the third slide rod 25 and located between the slider 41 and the third clamping block 33, and the adjustment element 43 is used to connect and fix the slider 41 and the third slide rod 25.
[0053] As is easily understood, during the clamping and assembly of the circuit board 200, the third clamping block 33 slides on the third slide bar 25, compressing the elastic element 42. Then, through the elastic force of the elastic element 42, the third clamping block 33 can better abut against the circuit board 200, cooperating with the first clamping block 31 and the second clamping block 32 to achieve a stable clamping. Simultaneously, the tightness of the elastic element 42 can be adjusted through the cooperation of the adjusting element 43 and the slider 41 to better adapt to circuit boards 200 of different specifications, and also to prevent excessive pressure from the third clamping block 33 on the circuit board 200, which could damage the circuit board 200.
[0054] Please refer to Figure 3 , Figure 3 This is a structural schematic diagram of the third slide bar 25 provided in this embodiment, combined with... Figures 1-3 It should be noted that in this embodiment, the adjusting member 43 is specifically an adjusting bolt. The third slide rod 25 has multiple threaded holes 251. The adjusting bolt passes through the slider 41 and engages with one of the threaded holes 251. In other words, by rotating the adjusting bolt to engage with the threaded hole 251, the slider 41 and the third slide rod 25 are connected and fixed. Furthermore, by engaging with threaded holes 251 at different positions, it can adapt to circuit boards 200 of different specifications, or adjust the elastic force of the elastic member 42 to apply a suitable clamping force to the circuit board 200.
[0055] Of course, in other embodiments, the adjusting member 43 can also be a pin, and multiple pin holes can be opened on the third slide rod 25. By cooperating with one of the pin holes, the position adjustment of the third clamping block 33 and the elastic force adjustment of the elastic member 42 can also be realized.
[0056] Additionally, it should be noted that in this embodiment, the elastic element 42 is specifically a spring, which is sleeved on the third slide rod 25. Of course, in other embodiments, the elastic element 42 can also be a sheet or a rubber sleeve or other elastic structure.
[0057] Please continue to combine Figure 1 In order to prevent the first clamping block 31 from sliding too far and falling off the first slide bar 23, in this embodiment, the fixing component 20 further includes a first limiting block 26, which is disposed at the end of the first slide bar 23 away from the first fixing block 21.
[0058] Similarly, in order to prevent the second clamping block 32 from sliding too far and falling off the second slide bar 24, in this embodiment, the fixing component 20 also includes a second limiting block 27, which is disposed at the end of the second slide bar 24 away from the first fixing block 21.
[0059] Furthermore, in this embodiment, the end of the first slide rod 23 near the first fixing block 21 is connected to the end of the second slide rod 24 near the first fixing block 21, and the first slide rod 23 and the second slide rod 24 are integrally formed. That is to say, the first slide rod 23 and the second slide rod 24 can be the same slide rod. During assembly, the slide rod directly passes through the first fixing block 21 and extends along the first direction. This integral forming design can save manufacturing costs and improve the efficiency of assembly tooling.
[0060] To further improve the clamping stability of the circuit board 200, the number of first clamping blocks 31 can be set to multiple, and multiple first clamping blocks 31 can be slidably disposed on the first slide bar 23; similarly, the number of second clamping blocks 32 can also be set to multiple, and multiple second clamping blocks 32 can be slidably disposed on the second slide bar 24. That is to say, in this embodiment, the number of first clamping blocks 31 and second clamping blocks 32 is one. Of course, in other embodiments, the number of first clamping blocks 31 and second clamping blocks 32 can also be two, three, or four, etc., and the specific number needs to be determined according to the actual specifications of the circuit board 200.
[0061] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the clamping assembly 30 provided in this embodiment, combined with... Figure 1 and Figure 4 The first clamping block 31 has a first clamping groove 311 on the side near the third clamping block 33, the second clamping block 32 has a second clamping groove 321 on the side near the third clamping block 33, and the third clamping block 33 has a third clamping groove 331 on the side near either the first clamping block 31 or the second clamping block 32. By providing the first clamping groove 311, the second clamping groove 321, and the third clamping groove 331, the opposite sides of the circuit board 200 can be engaged and fitted, achieving a stable installation of the circuit board 200.
[0062] It should be noted that in this embodiment, the first clamping groove 311 is specifically V-shaped, the second clamping groove 321 is specifically V-shaped, and the third clamping groove 331 is also specifically V-shaped. By setting such V-shaped clamping grooves, that is, the distance between the opposite side walls of the clamping groove gradually decreases and the opening is larger, the side of the circuit board 200 can be easily inserted into the clamping groove and then better abutted and fixed with the side walls of the clamping groove, thereby improving assembly efficiency and clamping stability.
[0063] Of course, in other embodiments, the shapes of the first clamping groove 311, the second clamping groove 321, and the third clamping groove 331 can also be C-shaped, U-shaped, Y-shaped, or other shapes.
[0064] In summary, the embodiments of this utility model provide a circuit board welding and fixing fixture 100, which includes a fixture plate 10, a fixing component 20, a clamping component 30, and an adjusting component 40. The fixing component 20 is disposed on the fixture plate 10; the clamping component 30 includes a first clamping block 31, a second clamping block 32, and a third clamping block 33.

By sliding the first clamping block 31 and the second clamping block 32 back and forth on the fixing component 20, circuit boards 200 of different lengths or widths can be adapted to clamp one side of them; while by sliding the third clamping block 33 back and forth on the fixing component 20, circuit boards 200 of different widths or lengths can be adapted to clamp the opposite side of them, thereby achieving the adaptation, clamping and fixing of circuit boards 200 of various specifications; at the same time, the third clamping block 33 is abutted by the adjusting component 40 and cooperates with the first clamping block 31 and the second clamping block 32, so that the three form a triangular structure, thereby achieving a stable clamping of the circuit board 200.
