Technical Field

[0001] This utility model relates to the field of PCB positioning technology, specifically to a PCB board fixing fixture for rapid positioning. Background Technology

[0002] During PCB manufacturing, it is necessary to position and fix the board, which requires the use of fixing fixtures.

[0003] According to CN211930984U, a PCB board positioning fixture with a foolproof structure is disclosed. It includes a base plate with multiple positioning slots arranged in an array. Each positioning slot is used to place the PCB board. At least one positioning post is provided in the positioning slot. The PCB board is provided with positioning holes that match the positioning posts. The positioning posts are sleeved in the positioning holes. Several fixing slots are opened on the side of each positioning slot. Each fixing slot is provided with a clamping component.

[0004] When using the aforementioned prior art, the PCB board is placed inside the positioning groove, and one side of the PCB board is pressed by springs and pressure plates. First, due to the limitation of the size of the positioning groove, this invention can only clamp and position PCB boards of a single size, and its application range is relatively limited. In addition, since the thickness of PCB boards is generally thin, after processing, the PCB board needs to be removed from the positioning groove, which is inconvenient when taking it out.

[0005] Based on this, this utility model designs a PCB board fixing fixture for rapid positioning to solve the above problems. Utility Model Content

[0015] Furthermore, an electric slide rail is fixedly installed inside the mounting base, and a positioning base plate is slidably connected to the mounting base, with the positioning base plate fixedly installed at the sliding end of the electric slide rail.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Example 1: Please refer to the accompanying drawings in the instruction manual. Figure 1 - Figure 3A quick-positioning PCB board fixing fixture includes a mounting base 1; a positioning base plate 2 disposed inside the mounting base 1, with PCB board bodies disposed on the upper side wall and right side of the positioning base plate 2, and a semi-hole formed on the upper side wall of the PCB board; a distance adjustment mechanism 3 disposed on the mounting base 1; a positioning mechanism 4 disposed on the positioning base plate 2; and a positioning mechanism 5 disposed on the positioning mechanism 4. The distance adjustment mechanism 3 includes two sets of movable push plates 31 slidably connected to the top of the mounting base 1, and a mounting groove 32 formed on the top of the mounting base 1; and a fixture fixedly installed at the bottom of the two sets of movable push plates 31 and slidably connected to the mounting groove 32. The connecting slider 34 is rotatably installed inside the mounting slot 32 and its outer wall extends to the right side of the mounting base 1. The outer wall of the bidirectional threaded rod 33 has forward and reverse threaded grooves, which are threaded to the two sets of connecting sliders 34 respectively. An auxiliary knob 35 is fixedly installed on the right outer wall of the bidirectional threaded rod 33. The positioning mechanism 4 includes positioning clamps 41 respectively set on the wall surfaces close to the two sets of movable push plates 31. Both sets of positioning clamps 41 are L-shaped. The wall surfaces close to the vertical ends of the two sets of positioning clamps 41 are fixedly installed with buffer pads. The vertical ends of the two sets of positioning clamps 41 clamp and position the PCB board.

[0031] In practical use, after the PCB board is processed, manually rotate the auxiliary knob 35 in the forward direction. The bidirectional threaded rod 33 rotates in the forward direction. Under the limit of the mounting slot 32, the two sets of connecting sliders 34 move away from each other, and the two sets of moving push plates 31 move away from each other along with the two sets of positioning clamps 41, thereby releasing the PCB board. Conversely, rotate the auxiliary knob 35 in the reverse direction, and the two sets of positioning clamps 41 move closer to clamp the PCB board. The operation is simple and convenient, and it is easy to clamp and release the product. In addition, by rotating the bidirectional threaded rod 33, the distance between the two sets of moving push plates 31 and the distance between the two sets of positioning clamps 41 can be changed, so that PCB boards of various widths can be clamped, which improves the applicability and clamping range.

[0032] Example 2: Based on Example 1, please refer to the accompanying drawings in the specification. Figure 1 - Figure 6The positioning mechanism 4 also includes rollers 42 rotatably mounted on the opposite sides of the two sets of positioning clamping plates 41; pressing blocks 43 fixedly mounted on the opposite sides of the two sets of movable push plates 31; the rollers 42 rollingly contacting the parallel ends of the pressing blocks 43 on the same side; limiting sliders 44 fixedly mounted on the bottom walls of the two sets of positioning clamping plates 41; the top wall of the positioning base plate 2 having a mounting groove 45; the limiting sliders 44 slidingly connected to the mounting groove 45; a limiting rod 46 fixedly mounted inside the mounting groove 45; and a spring 47 fixedly mounted on the opposite sides of the two sets of limiting sliders 44; the spring 47 slidingly connected to the limiting rod 46; and the spring 47 being in a compressed state.

[0033] The positioning mechanism 25 includes a connecting slide rod 51 slidably connected to the horizontal ends of the two sets of positioning clamping plates 41; a fixing plate 52 fixedly installed on the top of the two sets of connecting slide rods 51; a spring 2 53 fixedly installed on the wall surface of the two sets of fixing plates 52 and the same set of positioning clamping plates 41, the two sets of springs 2 53 being slidably connected to the connecting slide rods 51 on the same side, the springs 2 53 being in a compressed state; a mounting plate 54 fixedly installed on the outer wall of the two sets of connecting slide rods 51; an elastic pad 55 and a positioning post 56 fixedly installed at the bottom of the two sets of mounting plates 54, the two sets of positioning posts 56 being slidably connected to the elastic pads 55 on the same side, the outer walls of the two sets of positioning posts 56 being slidably inserted into the corresponding half-holes of the PCB board; a roller 2 57 rotatably installed on the top of the two sets of fixing plates 52; and a pressing block 2 58 fixedly installed on the horizontal ends of the two sets of moving push plates 31, the two sets of rollers 2 57 being in rolling contact with the parallel ends of the pressing block 2 58 on the same side.

[0034] Two sets of connecting slide rods 51 and two sets of springs 53 are provided, and the two connecting slide rods 51 and springs 53 in the same set correspond one-to-one.

[0035] An electric slide rail 6 is fixedly installed inside the mounting base 1. The positioning base plate 2 is slidably connected to the mounting base 1 and is fixedly installed on the sliding end of the electric slide rail 6.

[0036] In practical use, after the PCB board is processed, the positioning base plate 2 moves forward via the electric slide rail 6. Roller 2 57 moves along the parallel end of extrusion block 2 58. Roller 2 57 passes the inclined end of extrusion block 2 58 and finally separates from it. During this process, spring 2 53 extends, causing the fixing plate 52 to move upward. The connecting slide rod 51 carries the mounting plate 54 upward, and the elastic pad 55 moves upward, separating from the top wall of the PCB. Simultaneously, the positioning post 56 moves upward, separating from the half-hole of the PCB board. Furthermore, when roller 2 57 moves away from extrusion block 2 58, roller 1 42 moves from the parallel end of extrusion block 1 43 to the inclined surface of extrusion block 1 43. As the positioning base plate 2 continues to move forward, roller 1 42 passes the extrusion block 1 43. The inclined surface of 3 is away from the extrusion block 43. During this process, the spring 47 will extend along the outer wall of the limiting slide bar 46, the two sets of limiting sliders 44 will move away from each other, and the two sets of positioning clamps 41 will move away from each other and separate from the left and right sides of the PCB board, realizing the operation of releasing the PCB board. By limiting the half hole, clamping the left and right sides, and pressing the top of the PCB board, the stability of PCB board processing can be improved. At the same time, by moving the positioning base plate 2, multiple operations can be realized, which facilitates the use of the device. In addition, during the process of the two sets of positioning clamps 41 approaching the PCB board and the mounting plate 54 approaching the PCB board, the elastic pad 55 and the buffer pad can buffer the instantaneous force generated by the positioning clamps 41 and the mounting plate 54 on the PCB board, and play a protective role.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
