Detailed Description
The utility model is described in further detail below with reference to the figures and specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
As shown in fig. 1 to 6, a display circuit board soldering positioning apparatus of the present invention comprises a circuit board positioning frame 1 having two positioning areas and a cam knob 2 disposed outside each positioning area to press a display circuit board 3 placed in the positioning area on one side.
The outer side of each positioning area is provided with a corresponding raised positioning block, and the cam knob is positioned between two adjacent positioning blocks.
Specifically, the positioning area includes a first positioning area 11 and a second positioning area 12, the first positioning area is used for the operation of the step 1, the second positioning area is used for the operation of the step 2, the first positioning area has a first positioning block 20, a second positioning block 21, a third positioning block 23 and a fourth positioning block 24, a positioning area of the circuit board is formed among the four positioning blocks, and the positioning area extends to the outside.
The second positioning area 12 has a fifth positioning block 16, a sixth positioning block 17, a seventh positioning block 18 and an eighth positioning block 19, and a positioning area of the circuit board is formed among the four positioning blocks, and the positioning area extends outward to the outside.
The two positioning areas are separated by a protrusion 15, one side of the protrusion forms a plane structure, the other side of the protrusion is connected with a first positioning block 20, and a second positioning block 21 is connected to form a rectangular groove-shaped structure.
One side of each positioning area is provided with a low position area so as to avoid a power line of the display circuit board. Specifically, the first positioning area has a first low position area 10, the second positioning area has a second low position area 13, and particularly, a protruding area 14 higher than the second positioning area 12 is formed on one side of the second positioning area, and the protruding area 14 is connected with the second positioning area through a step positioning surface 22 to support the other side of the display circuit board, so that the protruding component on the other side of the display circuit board can be positioned in the second positioning area and can be supported by the protruding area 14 on the other side surface.
The cam knob 2 of the first positioning area is positioned on the lower area surface 9 lower than the first positioning area, and the cam knob 2 of the second positioning area is positioned on one side of the surface of the second positioning area.
The cam knob 2 is rotatably installed in a hole, the bottom of the cam knob is connected with a screw 14, the screw is installed in a stepped hole 15, a compression spring 13 is installed in a large-diameter hole in the bottom of the stepped hole, and the screw penetrates through the compression spring and is in threaded connection with the bottom of the cam knob.
Firstly assembling a circuit board positioning device, inserting the cam knob 2 into a corresponding hole of the circuit board positioning frame 1, and locking the pressure spring 13 into an installation hole position at the bottom of the cam knob 2 by using a combined screw 14; the pre-pressure of the pressure spring 13 can be adjusted by adjusting the depth of the combined screw 14, so that the screwing force of the cam knob 2 can be controlled, and when the circuit board 3 is placed on the device, the accurate pre-locking force of the circuit board 3 can be controlled.
