Description

Technical Field

[0001] The present application relates to the field of tooling technology, and in particular to a PCB board positioning fixture. Background Art

[0002] A printed circuit board (PCB) is an electronic device with specific functions, consisting of a printed circuit board (PCB) as its base carrier and various electronic components. Depending on the application scenario, PCB boards can be categorized as network cards, graphics cards, sound cards, and TV (Television) boards. TV boards are primarily used in televisions, primarily implementing signal processing, image display, and audio playback, which are unique to televisions.

[0003] After PCB manufacturing is complete, they need to be packaged and shipped. In related art, PCBs are transported to the corresponding processing equipment via a conveyor chain. A pushing mechanism then pushes the PCBs off the conveyor chain. A suction cup then removes the PCBs and places them in a packing box, where they are secured within the box using bolts and other components. To improve the stability of the pushing mechanism when pushing the PCBs, a PCB positioning jig is provided. When the pushing mechanism pushes, the positioning posts on the jig pass through the positioning holes on the PCB, securing the PCB to the pushing end of the mechanism and preventing horizontal movement relative to the mechanism. Because the layout of electronic components on PCBs varies between product models, the positions of the positioning holes on the PCBs also vary. Therefore, different PCB jigs are required for PCBs with different positioning holes. This not only increases the manufacturing cost of the PCBs, but also takes a long time to adjust the installation position of the new PCB jig, resulting in low PCB production efficiency.

[0035] See also Figure 1 and Figure 2 , Figure 1 This is a structural diagram of a PCB board positioning fixture 1 provided in an embodiment of the application. Figure 2It is a structural schematic diagram of another view of the PCB board positioning jig 1 provided in the embodiment of the application. The embodiment of the present application provides a PCB board positioning jig 1. The PCB board positioning jig 1 includes a base plate 2, an adjustment structure 3 and a positioning column 4. The base plate 2 has a mounting surface 21. The adjustment structure 3 includes a first adjustment member 6 and a second adjustment member 7. The first adjustment member 6 is slidably disposed on the mounting surface 21 along a first direction. The second adjustment member 7 is located on one side of the mounting surface 21 and is slidably disposed on the first adjustment member 6 along a second direction. The second adjustment member 7 can be detachably fixed relative to the first adjustment member 6. The positioning column 4 is fixed to the side of the second adjustment member 7 facing away from the mounting surface 21. The first direction and the second direction are perpendicular to each other and are both parallel to the mounting surface 21.

[0036] It can be understood that the first adjusting member 6 is detachably fixed to the base plate 2, so that the first adjusting member 6 can be both slidably disposed on the mounting surface 21 and fixed relative to the mounting surface 21. The second adjusting member 7 is detachably fixed to the first adjusting member 6, so that the second adjusting member 7 can both be slidably disposed on the first adjusting member 6 and fixed relative to the first adjusting member 6.

[0037] By sliding along the first direction, the first adjusting member 6 can move closer to or away from the stop block 9 .

[0038] Exemplarily, the first adjusting member 6 can be slidably disposed on the base plate 2 and fixed by bolt locking or an elastic supporting mechanism.

[0039] Exemplarily, the second adjusting member 7 can be slidably disposed on the base plate 2 and fixed by bolt locking or an elastic supporting mechanism.

[0040] When in use, first slide the first adjusting member 6 along the first direction according to the position of the positioning hole on the PCB board currently to be processed. When it slides to the desired position, fix the first adjusting member 6 relative to the base plate 2; then slide the second adjusting member 7 along the second direction. When it slides to the desired position, fix the second adjusting member 7 relative to the first adjusting member 6.

[0041] Then, after the transport chain transports the PCB board to the top of the pushing mechanism, the pushing end of the pushing mechanism drives the PCB board positioning jig 1 to move upward, so that the end of the positioning column 4 away from the base plate 2 passes through the positioning hole, and the PCB board contacts the PCB board positioning jig 1, and one side edge of the PCB board contacts the side of the stop block 9 facing the mounting surface 21.

[0042] Then, the pushing end of the pushing mechanism continues to move upward until the pushing mechanism pushes the PCB board to the adsorption position of the suction cup. The suction cup moves and adsorbs the PCB board, so that the PCB board can be removed from the positioning column 4.

[0043] In this embodiment, by providing the first adjusting member 6 and the second adjusting member 7, the positioning column 4 can be adjusted relative to the base plate 2 to match the positioning holes on PCB boards of different models, thereby improving the applicability of the PCB board and further reducing the manufacturing cost of the PCB board.

[0044] In addition, by adjusting the position of the positioning column 4 to match the positioning holes on different types of PCB boards, there is no need to debug repeatedly to determine the specific position of the PCB board positioning fixture 1 relative to the pushing mechanism, thereby improving the production efficiency of the PCB board.

[0045] See also Figure 3 , Figure 3 yes Figure 1 Enlarged view of point A in the middle. In some embodiments, the positioning column 4 includes a base 41 and a rod 42. The base 41 is connected to the second adjustment member 7. One end of the rod 42 is connected to the side of the base 41 facing away from the second adjustment member 7. The side of the base 41 facing away from the second adjustment member 7 is configured to support the PCB. This makes the positioning column 4 simple in structure and easy to manufacture. It also supports the PCB, thereby improving the positional stability of the PCB on the PCB positioning jig 1.

[0046] It can be understood that the PCB card sleeve is disposed on the rod portion 42 and contacts the side of the base 41 facing away from the second adjusting member 7 .

[0047] See also Figure 3 In some embodiments, the other end of the rod 42 is formed into a hemispherical structure 43. This not only allows the spherical surface of the hemispherical structure 43 to guide the rod 42 and the positioning hole of the PCB, but also avoids sharp corners at the contact point between the rod 42 and the PCB, thereby preventing damage to the PCB.

[0048] See also Figure 3 In some embodiments, an elastic rubber pad 44 is provided on the side of the base 41 facing away from the second adjusting member 7. This not only ensures soft contact between the base 41 and the PCB, but also increases friction between the PCB and the base 41, preventing the PCB from shaking when pushed by the pushing mechanism, thereby improving the fixation of the PCB relative to the PCB positioning jig 1.

[0049] See also Figure 1 and Figure 2In some embodiments, the first adjusting member 6 includes a first adjusting block 61 and a first bolt 62. The first adjusting block 61 is provided with a first through slot 63. The extension direction of the first through slot 63 is parallel to the first direction. One side of the base plate 2 is inserted into the first through slot 63. The first bolt 62 is located on the side of the base plate 2 facing away from the mounting surface 21. The first bolt 62 is threadedly connected to the first adjusting block 61. The end of the rod 42 of the first bolt 62 abuts against the surface of the base plate 2 facing away from the mounting surface 21. The side of the first adjusting block 61 away from the first bolt 62 is connected to the second adjusting member 7.

[0050] To adjust the position of the positioning column 4, first slide the first adjustment block 61 along the first direction. When it slides to the desired position, tighten the first bolt 62 so that the end of the rod 42 of the first bolt 62 abuts against the surface of the base plate 2 facing away from the mounting surface 21, thereby fixing the first adjustment block 61 relative to the base plate 2. In this way, the position adjustment of the first adjustment member 6 is completed.

[0051] In this embodiment, by adopting the first adjusting member 6 of the above structure, not only the structure of the first adjusting member 6 is simple and easy to manufacture, but also the position adjustment and fixing operations are simple, thereby improving the adjustment efficiency of the PCB board positioning fixture 1.

[0052] See also Figure 4 and Figure 5 , Figure 4 A top view of the PCB board positioning fixture 1 provided in the embodiment of the application, Figure 5 yes Figure 4 Cross-sectional view of BB in the figure. In some embodiments, the second adjusting member 7 includes a slide rail 71, a second adjusting block 72, and a second bolt 73. The slide rail 71 is arranged on the first adjusting member 6. The second adjusting block 72 is provided with a second through slot 74. The extension direction of the second through slot 74 is parallel to the second direction. The slide rail 71 is inserted into the second through slot 74. The second bolt 73 is threadedly connected to the second adjusting block 72. The end of the rod 42 of the second bolt 73 abuts against the slide rail 71. The positioning column 4 is fixed to the side of the second adjusting block 72 facing away from the mounting surface 21.

[0053] To adjust the position of the positioning column 4, slide the second adjustment block 72 along the second direction. When it slides to the desired position, tighten the second bolt 73 so that the end of the rod 42 of the second bolt 73 abuts against the slide rail 71, thereby fixing the second adjustment block 72 relative to the slide. In this way, the position adjustment of the second adjustment member 7 is completed.

[0054] In this embodiment, by adopting the second adjusting member 7 of the above structure, not only the structure of the second adjusting member 7 is simple and easy to manufacture, but also the position adjustment and fixing operations are simple, thereby improving the adjustment efficiency of the PCB board positioning fixture 1.

[0055] See also Figure 5 In some embodiments, a first contact post 75 is provided on the side of the second adjustment block 72 facing the first adjustment member 6. The axis of the first contact post 75 is parallel to the slide rail 71. The first contact post 75 is semi-cylindrical. The flat side of the first contact post 75 is connected to the second adjustment block 72, and its cylindrical surface contacts the first adjustment member 6. In this way, the first contact post 75 can increase the contact surface between the second adjustment block 72 and the first adjustment member 6, thereby improving the positional stability of the second adjustment block 72.

[0056] See also Figure 1 In some embodiments, the PCB board positioning fixture 1 further includes a plurality of support blocks 8. The plurality of support blocks 8 are fixed to the mounting surface 21. The sides of the plurality of support blocks 8 facing away from the mounting surface 21 are coplanar. The sides of the plurality of support blocks 8 facing away from the mounting surface 21 are configured to support the PCB board.

[0057] Specifically, a side of the plurality of support blocks 8 facing away from the mounting surface 21 is coplanar with a side of the elastic rubber pad 44 facing away from the mounting surface 21 .

[0058] Exemplarily, there are three support blocks 8 , which are spaced apart on the mounting surface 21 .

[0059] In this embodiment, by providing the support block 8, the contact surface between the PCB board positioning jig 1 and the PCB board can be increased, thereby improving the support reliability of the PCB board positioning jig 1 on the PCB board.

[0060] See also Figure 1 In some embodiments, the PCB board positioning fixture 1 further includes a stopper 9. The stopper 9 is disposed on a side edge of the base plate 2 and protrudes from the mounting surface 21. A plurality of second contact pins 91 are disposed on the side of the stopper 9 facing the mounting surface 21. The axes of the second contact pins 91 are perpendicular to the mounting surface 21. The side of the second contact pins 91 facing the mounting surface 21 is convex and cylindrical.

[0061] In this embodiment, by providing the stopper 9 , the PCB board on the PCB board positioning jig 1 can be assisted in positioning, thereby improving the position stability of the PCB board on the PCB board positioning jig 1 .

[0062] In addition, the stopper 9 contacts the PCB through the plurality of second contact pins 91, so that the PCB positioning fixture 1 is in line-surface contact with the PCB at the stopper 9. This reduces the difficulty of manufacturing the PCB positioning fixture 1 compared to surface-surface contact.

[0063] See also Figure 1 In some embodiments, there are two adjustment structures 3 and two positioning posts 4. The two adjustment structures 3 are respectively disposed at both ends of the base plate 2. The two positioning posts 4 are disposed correspondingly to the two adjustment structures 3.

[0064] In this embodiment, by providing two adjustment structures 3 and positioning posts 4, the PCB board positioning jig 1 has multiple positions for cooperating with the PCB board, thereby improving the position stability of the PCB board on the PCB board positioning jig 1.

[0065] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0066] The embodiments, implementation methods and related technical features of the present application can be combined and replaced with each other without conflict.
