Technical Field

[0001] The utility model relates to the field of electronic manufacturing, and particularly relates to a universal fixture for SMT chip mounting. Background Art

[0002] SMT, surface mount technology, is a technology widely used in the field of electronic manufacturing, which is used to directly mount electronic components on the surface of a printed circuit board. Compared with the traditional through-hole insertion technology, SMT technology has the advantages of higher density, better electrical performance and lower cost. The universal fixture for SMT chip mounting is a tool used to support and position a printed circuit board, mainly used in the SMT production line, especially for positioning and fixing the printed circuit board before SMT chip mounting and soldering.

[0003] In the existing SMT chip mounting, usually the printed circuit board is placed on the universal fixture for positioning and then SMT chip mounting and soldering are carried out. However, in the actual operation process of SMT chip mounting processing, the printed circuit board is prone to displacement, which easily leads to position deviation of component soldering, thus affecting the quality and efficiency of chip mounting processing.

[0004] Therefore, it is necessary to design a universal fixture for SMT chip mounting that can position and install FPC boards of different sizes and types, improve the flexibility of use, and can fix the FPC board to prevent displacement during processing, thereby improving the quality and efficiency of processing.

[0009] More preferably, a plurality of positioning holes are opened on the carrier.

[0010] More preferably, the clamping assembly includes a connecting seat, a moving plate and a screw rod. Connecting seats are connected to the sliders, and the connecting seats are all slidably connected to the carrier. Screw rods are threadedly connected to the connecting seats, the lower parts of the screw rods are rotatably connected to the moving plates, the moving plates are in contact and cooperation with the adjacent connecting seats, and the moving plates are in contact with the FPC board.

[0011] More preferably, handles are provided on the screw rods.

[0012] The beneficial effects of the present utility model are as follows: 1. By pulling the other connecting seats to move, the other connecting seats are made to contact the FPC board, and then by reversely rotating the screw rod with the handle, the moving plate moves reversely to fix the FPC board, so that FPC boards of different sizes and types can be positioned and installed, improving the flexibility of use, and the FPC board can be fixed to prevent displacement during the processing, improving the processing quality and efficiency.

[0018] The present utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which the presently preferred embodiments of the present utility model are shown. However, the present utility model can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the present utility model to those skilled in the art.

[0019] An SMT patch general fixture, as Figures 1 - 3As shown in the figure, it includes a base 1, a carrier 3, a slider 6, a connecting seat 7, a moving plate 8 and a screw 9. Four sliding grooves 2 are opened on the base 1 for easy movement. The carrier 3 is snap-connected to the upper side of the base 1. A scale 4 is provided on the upper side of the right part of the carrier 3 for easy positioning. Four positioning holes 5 are opened on the carrier 3 for easy fixation. Four sliders 6 are slidably connected to the base 1. Connecting seats 7 are connected to the sliders 6. The connecting seats 7 are all slidably connected to the carrier 3. Screws 9 are threadedly connected to the connecting seats 7. The lower parts of the screws 9 are rotatably connected to the moving plates 8. The moving plates 8 are all in contact and cooperation with the adjacent connecting seats 7. Handles are provided on the screws 9 for easy hand-held rotation of the screws 9. An FPC board 10 is placed on the carrier 3. The moving plates 8 are all in contact with the FPC board 10.

[0020] When SMT patching is required, this device can be used. Take this device to the place where SMT patching is processed and place this device on the desktop or workbench so that the base 1 contacts the desktop or workbench. Then make the base 1 snap-connected to the positioning holes 5 on the carrier 3 to fix the carrier 3. Then rotate the screw 9 through the handle. Under the action of the thread, the screw 9 moves, driving the moving plate 8 to move. Then place the FPC board 10 on the carrier 3 so that the FPC board 10 contacts one of the connecting seats 7. Then pull the other connecting seats 7 to move by hand, so that the sliders 6 move along the sliding grooves 2 on the base 1. Move to the appropriate position according to the scale 4 so that the other connecting seats 7 contact the FPC board 10. Then rotate the screw 9 in the reverse direction through the handle. Under the action of the thread, the screw 9 moves in the reverse direction, driving the moving plate 8 to move in the reverse direction and contact the FPC board 10 to fix the FPC board 10. Thus, the positioning and installation of FPC boards 10 of different sizes and types can be carried out, improving the flexibility of use, and the FPC board 10 can be fixed to prevent displacement during the processing, improving the processing quality and efficiency. After positioning, SMT patching and soldering are carried out.
