[0025] The terms used herein are for the purpose of describing various embodiments only and are not intended to be limiting. As used herein, the singular is intended to include the plural, unless the context clearly indicates otherwise. It will also be understood that the terms "comprising" and / or "having" when used in this specification specify the presence of a stated feature, number, step, operation, component, element, or combination thereof, and do not preclude the presence or addition of one or more other features, numbers, steps, operations, components, elements, or groups thereof.

[0026] Schematic PCB board soldering positioning device, reference Figures 2 to 4 According to a preferred embodiment of the present invention, a positioning device for PCB board soldering is provided. Figure 2 and Figure 3 As shown, the positioning device for PCB board repair soldering includes a clamping seat 10, and two clamping members 20 are provided on the clamping seat 10. One of the clamping members 20 is fixedly installed on the clamping seat 10, and the other clamping member 20 is slidably set on the clamping seat 10.

[0027] It should be noted that if Figure 3 As shown, each clamping member 20 has a recessed clamping slot 201. The two clamping members 20 are symmetrically arranged, and the width of the clamping slots 201 is equal to the width of the PCB to be clamped. By sliding each clamping member 20 on the clamping base 10, PCBs of varying lengths can be accommodated. It should also be noted that before a PCB is placed in the clamping slot 201 between the two clamping members 20, the distance between the bottom walls of the two clamping slots 201 is slightly greater than the length of the PCB to be clamped, making it easier for repair soldering personnel to place the PCB between the two clamping members 20.

[0028] However, since the distance between the bottom walls of the two clamping grooves 201 is slightly larger than the length of the PCB to be clamped, the PCB still shakes during the repair soldering process.

[0029] In view of this, in order to eliminate the small gap between the PCB board to be clamped and the clamping groove 201, as shown in FIG. Figure 3 As shown, an air bag 202 is provided on each of the two clamping members 20 facing each other, and each of the air bags 202 is connected to an external air source.

[0030] More specifically, the bottom wall of each clamping groove 201 has a recessed receiving groove (not shown in the figure), within which is located the inflatable bladder 202. Initially, the inflatable bladder 202 is deflated. Each inflatable bladder 202 has an air inlet and an air outlet (not shown in the figure). After the PCB to be clamped is placed between the two clamping members 20, an external air source is allowed to inflate the bladder 202 through the air inlet. The air-filled bladder 202 gradually expands and fills the tiny gap between the PCB to be clamped and the clamping groove 201, preventing the PCB from shaking. Clearly, compared to the prior art, the embodiments of the present application have the advantage of securing the PCB and preventing it from shaking during the soldering process.

[0031] Furthermore, due to the different distribution positions of solder joints on PCB boards of different lengths, in order to facilitate the repair workers to solder at a more comfortable angle, such as Figure 2 As shown, the positioning device for PCB board repair welding also includes an intermediate seat 30, and the clamping seat 10 is rotatably mounted on the intermediate seat 30 through a bearing.

[0032] Specifically, if Figure 2 As shown, the clamping seat 10 has an insert shaft 101 on one side close to the intermediate seat 30, and the insert shaft 101 is located at the center of the clamping seat 30. The intermediate seat 30 has a stepped hole 301 on one side close to the clamping seat 10, and a bearing is embedded in the end of the stepped hole 301 with a larger aperture. The insert shaft 101 cooperates with the bearing and extends into the stepped hole 301.

[0033] Furthermore, in order to realize that the clamping seat 10 can be fixed at a certain angle after rotating a predetermined angle, as shown in FIG. Figure 2 and Figure 4 As shown, the positioning device for PCB board repair soldering also includes a plurality of spring clips 40. The bottom of the clamping seat 10 has a ring-shaped card slot 102. Each of the spring clips 40 is located between the clamping seat 10 and the intermediate seat 30, and one end of each spring clip 40 is fixedly connected to the intermediate seat 30. The fixed connection method includes but is not limited to welding. The other end of the spring clip 40 extends into the corresponding card slot 102 and abuts against the slot wall of the card slot 102.

[0034] More specifically, each of the slots 102 is a triangular groove, and each of the spring pieces 40 has two symmetrically arranged inclined surfaces (not shown in the figure) at one end facing away from the middle seat 30 , and each of the inclined surfaces is in contact with the corresponding slot wall of the slot 102 .

[0035] It should be noted that when the clamping seat 10 is subjected to a circumferential force and rotates, each of the spring pieces 40 is deformed and disengaged from the corresponding slot 102. When the clamping seat 10 is rotated to a predetermined angle, each of the spring pieces 40 extends into the newly corresponding slot 102 and provides resistance to limit the circumferential rotation of the clamping seat 10.

[0036] Furthermore, since the heights of the repair welders are different, in order to help the repair welders find the most comfortable height, such as Figure 2 As shown, the positioning device for PCB board repair soldering also includes a base 50, the intermediate seat 30 is located between the clamping seat 10 and the base 50, the base 50 has a lifting cavity 501, and the intermediate seat 30 has an extension portion 302 on a side close to the base 50, and the extension portion 302 is arranged in the lifting cavity 501 in a liftable manner.

[0037] In order to fix the height position of the extending portion 302 in the lifting chamber 501, as shown in FIG. Figure 2 As shown, the PCB board repair positioning device also includes a first fastener 60, and a side wall of the lifting chamber 501 has a first threaded hole 5011. One end of the first fastener 60 is threadedly connected to the first threaded hole 5011 and abuts against or separates from the insertion portion 302.

[0038] Furthermore, a guide is provided for the rotation of the clamping seat 10 relative to the intermediate seat 30, such as Figure 2 As shown, the clamping seat 10 has a plurality of guide posts 103 on one side close to the intermediate seat 30 , and the intermediate seat 30 has an annular groove 303 on one side close to the clamping seat 10 , and each of the guide posts 103 extends into the annular groove 303 .

[0039] Furthermore, in order to realize that the clamping member 20 is slidably arranged on the clamping seat 10, as shown in FIG. Figure 3 As shown, the bottom of both sides of the clamping member 20 slidably arranged on the clamping seat 10 has a protrusion (not marked in the figure), and the side of the clamping seat 10 facing away from the intermediate seat 30 has two sliding grooves 104, and the two protrusions are slidably arranged in the corresponding sliding grooves 104.

[0040] In addition, if Figure 3 As shown, the positioning device for PCB board repair soldering also includes a second fastener 70, and one side of the clamping member 20 slidably set on the clamping seat 10 has a waist-shaped groove 203, and one end of the second fastener 70 passes through the waist-shaped groove 203 and is threadedly connected to the clamping seat 10.

[0041] In summary, the positioning device for PCB board repair soldering based on the embodiment of the present application is explained, which provides the positioning device for PCB board repair soldering with advantages such as fixing the PCB board and preventing the PCB board from shaking during the repair soldering process.

[0042] It is worth mentioning that in the embodiments of the present application, the PCB repair soldering positioning device has a simple structure, does not involve complex manufacturing processes and does not require expensive materials, and is highly economical. Furthermore, for manufacturers, the PCB repair soldering positioning device provided in this application is easy to produce and is low-cost, which is more conducive to controlling production costs and further promoting product promotion and use.
