Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing technology, specifically relating to an auxiliary support for welding the front and back sides of a PCB board. Background Technology

[0002] A PCB, or Printed Circuit Board, is a support structure for electronic components and a carrier for their electrical interconnection. During PCB processing or repair, it is often necessary to solder different electronic components onto the PCB. Some PCBs have circuitry on both sides, requiring soldering on both sides. Current soldering processes typically use clamps to hold the PCB, removing it after soldering on one side, clamping it with the other side facing up, and then continuing the soldering process. This process of removing and re-clamping is cumbersome and inefficient. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a PCB board front and back welding auxiliary bracket that can fix the PCB board and quickly flip the PCB board.

[0004] Technical solution: To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A PCB board front and back welding auxiliary bracket includes a base plate, a hinge seat connected to the base plate, a support block connected to the hinge seat, a support shaft connected to the support block, a displacement seat connected to the support shaft, a first fixing plate disposed on the support block, and a second fixing plate disposed on the displacement seat. A first clamping plate is rotatably connected to the first fixing plate, and a second clamping plate is rotatably connected to the second fixing plate.

[0006] Furthermore, both the first clamping plate and the second clamping plate are provided with a first limiting groove, and the two first limiting grooves are symmetrically arranged.

[0007] Furthermore, an anti-slip pad is provided inside the first limiting groove.

[0008] Furthermore, the first or second fixing plate is provided with a top plate, and a first locking bolt is threadedly connected to the top plate. The first locking bolt is used to abut against the first or second clamping plate.

[0009] Furthermore, the support shaft is provided with intermittent external threads and a rectangular surface, and the rectangular surface is provided with a sliding groove.

[0010] Furthermore, the displacement seat includes two symmetrically arranged first sliding plates, a first adjusting nut disposed between the two first sliding plates, and a seat plate connected to the two first sliding plates. The first sliding plate is provided with a first through hole corresponding to the support shaft, and the first sliding plate is provided with a slider corresponding to the slide groove. The internal thread of the first adjusting nut corresponds to the intermittent external thread.

[0011] Furthermore, there are two rectangular surfaces, which are arranged symmetrically.

[0012] Furthermore, the hinge seat includes a U-shaped frame, an intermediate plate corresponding to the U-shaped frame, a hinge shaft passing through the U-shaped frame and the intermediate plate, and a locking nut threadedly connected to the hinge shaft.

[0013] Furthermore, the base plate has one or more second through holes.

[0014] Furthermore, a magnet block is provided on the lower end face of the base plate.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0016] 1. By setting two fixed plates and two clamping plates, the clamping plates can rotate relative to the fixed plates. After one side of the PCB board is soldered, it can be rotated directly to perform soldering work on the other side, which is convenient and quick.

[0017] 2. By setting the first locking bolt, the clamp can be fixed at a predetermined angle, so that the PCB board is kept at a predetermined front-to-back tilt angle. By setting the hinge seat, the fixing plate and clamp can be adjusted left and right, so that the PCB board is kept at a predetermined left-to-right tilt angle. The PCB board faces different angles, which facilitates the soldering operation and improves the work efficiency.

[0018] 3. Set up a support shaft and a displacement seat. The displacement seat drives the second clamping plate to move left and right. The first adjusting nut can quickly clamp the two clamping plates onto the PCB board. It is suitable for PCB boards of different lengths. Attached Figure Description

[0027] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0028] like Figure 1 and Figure 2 As shown, a PCB board front and back welding auxiliary bracket includes a base plate 1, a hinge seat 2, a support block 3, a support shaft 4, a displacement seat 5, a first fixing plate 61, and a second fixing plate 62. The base plate 1 is a rectangular plate used to place on a workbench. The hinge seat 2 is connected to the right side of the upper surface of the base plate 1. The hinge seat 2 includes a U-shaped frame 21, an intermediate plate 22, a hinge shaft 23, and a locking nut 24. The lower end of the intermediate plate 22 is connected to the base plate 1. The U-shaped frame 21 is upside down on the intermediate plate 22. The U-shaped frame 21 and the intermediate plate 22 are provided with center holes corresponding to the hinge shaft 23. The hinge shaft 23 passes through the center holes and passes through the U-shaped frame 21 and the intermediate plate 22. The hinge shaft 23 is provided with threads. The locking nut 24 is threadedly connected to the hinge shaft 23. The locking nut 24 is an existing wing nut. Tightening the locking nut 24 can press the U-shaped frame 21 and the intermediate plate 22 to fix the relative position of the U-shaped frame 21 and the intermediate plate 22. After loosening the locking nut 24, the U-shaped frame 21 can rotate relative to the intermediate plate 22, thereby adjusting the position.

[0029] like Figure 1 and Figure 2 As shown, the lower end of the support block 3 is connected to the hinge seat 2, and the support shaft 4 is connected to one side of the support block 3. The support shaft 4 is located in the upper area of ​​the base plate 1 and is parallel to the base plate 1. The support shaft 4 is provided with an intermittent external thread 41 and a rectangular surface 42. There are two rectangular surfaces 42. The support shaft 4 is a whole stud with external threads. Both sides are cut off along its axial direction. The remaining external threads after the cut-off form the intermittent external thread 41. The intermittent external thread 41 includes upper and lower threads. The planes formed on both sides of the stud after the cut-off are rectangular surfaces 42. The two rectangular surfaces 42 are symmetrical. A groove 421 is provided in the middle of the rectangular surface. The groove 421 is a rectangular groove and extends along the axial direction of the support shaft 4.

[0030] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the displacement seat 5 is movably connected to the support shaft 4. The displacement seat 5 includes two first slide plates 51, a first adjusting nut 52, and a seat plate 53. The two first slide plates 51 are symmetrically arranged, and the first adjusting nut 52 is located between the two first slide plates 51. The seat plate 53 is parallel to the base plate 1 and connected to the top of the two first slide plates 51. The first slide plate 51 is provided with a first through hole 501 corresponding to the support shaft 4. The support shaft 4 passes through the two first through holes 501. The first slide plate 51 is provided with a slider 511 corresponding to the slide groove 421. There are two sliders 511. The sliders 511 are rectangular blocks. When the two first slide plates 51 are fitted onto the support shaft 4, the sliders 511 move left and right on the slide groove 421 to guide and restrict the rotation of the two first slide plates 51, so that the two first slide plates... 51 can only move left and right but cannot rotate. The internal thread of the first adjusting nut 52 corresponds to the intermittent external thread 41, so it can be threaded onto the support shaft 4. In use, the first adjusting nut 52 is placed between the two first slide plates 51. The outer end of the support shaft 4 is then passed through one of the first slide plates 51. The first adjusting nut 52 is then threaded onto the support shaft 4. The first adjusting nut 52 is continuously turned. The support shaft 4 passes through the first adjusting nut 52 and then through the other first slide plate 51. At this time, when the first adjusting nut 52 is turned, its position can be moved left and right. The first adjusting nut 52 pushes the left or right first slide plate 51, which can drive the entire displacement seat 5 to move left or right. When the displacement seat 5 moves to the right, it moves closer to the support block 3. When the displacement seat 5 moves to the left, it moves away from the support block 3.

[0031] like Figure 1 , Figure 3 and Figure 8As shown, the first fixing plate 61 is mounted on the support block 3, and the second fixing plate 62 is mounted on the seat plate 53 of the displacement seat 5. The first fixing plate 61 is connected to the first clamping plate 71, and the second fixing plate 62 is connected to the second clamping plate 72. Both the first clamping plate 71 and the second clamping plate 72 are circular plates. A central shaft 74 is connected to the center of the first clamping plate 71 and the second clamping plate 72. Bearings 75 are provided on the first fixing plate 61 and the second fixing plate 62 at positions corresponding to the central shaft 74. The central shaft 74 is connected to the bearings 75. The two clamping plates are rotatably connected to the two fixing plates through the central shaft 74. The first clamping plate 71 and the second clamping plate 72 are arranged opposite each other and at the same height. The inner surfaces of the first clamping plate 71 and the second clamping plate 72 are provided with first limiting grooves 701. The first limiting grooves 701 are strip-shaped grooves. The two first limiting grooves 701 are symmetrically arranged and are used to place the PCB board 9. After placing one side of the PCB board 9 on the first limiting groove 701 of the first clamping plate 71, tightening the first adjusting nut 52 causes the displacement seat 5 to move to the right. The displacement seat 5 causes the second fixing plate 62 and the second clamping plate 72 to move to the right as a whole until the other side of the PCB board 9 enters the first limiting groove 701 of the second clamping plate 72. After tightening the first adjusting nut 52, the first clamping plate 71 and the second clamping plate 72 clamp the PCB board 9. In order to protect the PCB board 9, the first limiting groove 701 is provided with an anti-slip pad 73. The anti-slip pad 73 is made of rubber material and can play an anti-slip role while protecting the PCB board 9. Since the first clamping plate 71 is rotatably connected to the first fixing plate 61, and the second clamping plate 72 is rotatably connected to the second fixing plate 62, rotating one clamping plate can drive the PCB board 9 to rotate. The second fixing plate 62 is provided with a top plate 63 (the top plate 63 can also be set on the first fixing plate 61 as needed). The top plate 63 is threaded with a first locking bolt 631. The position of the first locking bolt 631 corresponds to the position of the second clamping plate 72. The first locking bolt 631 passes through the top plate 63. When the first locking bolt 631 is tightened, the top end of the first locking bolt 631 moves downward and abuts against the outer circumferential side wall of the second clamping plate 72, thereby restricting the rotation of the second clamping plate 72. After one side of the PCB board 9 is soldered, the first locking bolt 631 is loosened, and the first clamping plate 71 or the second clamping plate 72 is rotated to drive the PCB board 9 to flip so that the other side of the PCB board 9 faces upward. The first locking bolt 631 is then tightened to perform the soldering work on the other side.

[0032] like Figure 1 , Figure 7 and Figure 8 As shown, in this embodiment, when using the auxiliary bracket, rotating the first adjusting nut 52 can adjust the position of the displacement seat 5 and the second clamping plate 72, thereby clamping different types of PCB boards 9. When different left and right tilt angles are required, the U-shaped frame 21 can be rotated and the locking nut 24 tightened, so that the PCB board 9 can be in different left and right tilt angles, such as... Figure 8 As shown, after rotating the U-shaped bracket 21, the PCB board 9 is perpendicular to the base plate 1, which facilitates soldering work at different angles and improves soldering efficiency. The base plate 1 can be placed directly to form a support. The base plate 1 has two second through holes 11, which can be used to fix the base plate 1 with bolts or other means. The lower end face of the base plate 1 has a magnet 12, which can be used to fix the position of the base plate 1. If the PCB board 9 is rotated at a large angle and the center of gravity of the bracket is unstable, it can be fixed through the second through holes 11 or magnetically, or a heavy object can be placed on the base plate 1 to press it down.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
