Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning tooling technology, specifically a positioning tooling for mounting chips on a mobile phone PCB board. Background Technology
[0002] A PCB, or printed circuit board, is a provider of electrical connections for electronic components. Its development spans over a century, and its design primarily involves layout design. The main advantages of using PCBs are significantly reduced wiring and assembly errors, and improved automation and productivity.
[0003] During the surface mount technology (SMT) process of PCB boards, clamping and positioning are required. However, conventional positioning fixtures are cumbersome to operate and not easy to adjust according to the size of the PCB board. Since mobile phone PCB boards are often small, traditional positioning fixtures are inconvenient for operators to use, reducing the positioning stability of mobile phone PCB boards.
[0004] Therefore, it is necessary to design a positioning fixture for mobile phone PCB board mounting to address the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a positioning fixture for mobile phone PCB board patch assembly, so as to solve at least one technical problem existing in the above-mentioned background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A positioning fixture for mobile phone PCB board mounting includes:
[0008] A workbench, the surface of which is provided with an adjustment groove, a drive rod is provided in the adjustment groove, and an adjustment block is connected to the outside of the drive rod, the adjustment block also being located in the adjustment groove;
[0009] A top plate, on the surface of which a positioning frame is installed, a pressure plate is provided inside the positioning frame, and an adjusting rod and a limiting rod are respectively installed on the surface of the pressure plate, and the adjusting rod and the limiting rod are connected to the positioning frame.
[0010] A vertical plate is fixed to one end surface of the workbench, and a positioning frame is also installed on the vertical plate.
[0011] Preferably, the drive rod is rotatably connected to the worktable.
[0012] Preferably, the drive rod and the adjusting block are connected by a through thread, and the adjusting block is slidably connected to the worktable through an adjusting groove.
[0013] Preferably, the positioning frame is a horizontally placed "U"-shaped structure, and the openings of the positioning frame on the vertical plate and the positioning frame on the top plate face each other.
[0014] Preferably, the pressure plate is located inside the positioning frame, and both the pressure plate and the positioning frame have anti-slip pads on their opposite surfaces.
[0015] Preferably, the adjusting rod and the pressure plate are rotatably connected.
[0016] Preferably, the adjusting rod and the positioning frame are connected by a through thread.
[0017] Preferably, the limiting rods are symmetrically distributed at both ends of the pressure plate.
[0018] Preferably, the limiting rod and the positioning frame are connected by a through sliding connection.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] When the drive rod is rotated on the worktable, it pushes the adjusting block through the thread, causing the top plate to move closer to the vertical plate. This helps adjust the distance between the top and vertical plates, allowing the edge of the mobile phone PCB board to rest within two different positioning frames. Twisting the adjusting rod allows it to move along the positioning frame through the thread, which helps the adjusting rod push the pressure plate to cooperate with the positioning frame, stably clamping the edge of the mobile phone PCB board and facilitating stable positioning to accommodate the thickness of the PCB board.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-4 One embodiment provided by this utility model:
[0031] A positioning fixture for mobile phone PCB board mounting includes:
[0032] The worktable 1 has an adjustment groove 2 on its surface. A drive rod 3 is installed in the adjustment groove 2. The drive rod 3 is rotatably connected to the worktable 1, which facilitates the rotation of the drive rod 3 on the worktable 1. An adjustment block 4 is connected to the outside of the drive rod 3. The adjustment block 4 is also located in the adjustment groove 2. The drive rod 3 and the adjustment block 4 are connected by a through thread. The adjustment block 4 is slidably connected to the worktable 1 through the adjustment groove 2. When the drive rod 3 rotates, the drive rod 3 can push the adjustment block 4 to slide within the adjustment groove 2 through the thread.
[0033] Vertical plate 11 is fixed to one end surface of workbench 1, and positioning frame 6 is also installed on vertical plate 11.
[0034] In one embodiment, the positioning frame 6 is a horizontally placed "U"-shaped structure. The openings of the positioning frame 6 on the vertical plate 11 and the positioning frame 6 on the top plate 5 face each other, which is conducive to the cooperation between the positioning frame 6 on the vertical plate 11 and the positioning frame 6 on the top plate 5 to stably clamp the mobile phone PCB board.
[0035] In one preferred embodiment, the pressure plate 7 is located inside the positioning frame 6. Anti-slip pads 8 are provided on the opposing surfaces of the pressure plate 7 and the positioning frame 6. The pressure plate 7 can cooperate with the positioning frame 6 to clamp the edge of the mobile phone PCB board.
[0036] In one embodiment, the adjusting rod 9 is rotatably connected to the pressure plate 7, and the adjusting rod 9 is threadedly connected to the positioning frame 6. When the adjusting rod 9 is turned, the adjusting rod 9 can move on the positioning frame 6 through the thread, and at this time the displaced adjusting rod 9 can also push the pressure plate 7 to move.
[0037] In one preferred embodiment, the limiting rods 10 are symmetrically distributed at both ends of the pressure plate 7. The limiting rods 10 and the positioning frame 6 are connected by a through sliding connection. The limiting rods 10 slide up and down on the positioning frame 6. The two cooperate to prevent the pressure plate 7 from rotating synchronously with the adjusting rod 9, thereby improving the stability of the pressure plate 7 in adjusting its vertical displacement.
[0038] The working principle of this utility model is as follows: First, the mobile phone PCB board to be positioned is placed between the vertical plate 11 and the top plate 5. Then, when the drive rod 3 is rotated on the worktable 1, the drive rod 3 will push the adjusting block 4 through the thread to move the top plate 5 closer to the vertical plate 11, which is beneficial to adjust the distance between the top plate 5 and the vertical plate 11 until the positioning frame 6 on the top plate 5 and the vertical plate 11 contacts the edge of the mobile phone PCB board, so that the edge of the mobile phone PCB board rests in the two different positioning frames 6. Then, the adjusting rod 9 is turned, and the adjusting rod 9 can be moved on the positioning frame 6 through the thread. The moved adjusting rod 9 will push the pressure plate 7 to cooperate with the positioning frame 6, so that the two can stably clamp the edge of the mobile phone PCB board through the anti-slip pad 8, which is beneficial to adapt to the thickness of the mobile phone PCB board and stably position it.
