Small-sized hand vibration preventing image sensing module

Abstract

The invention relates to a small-sized hand vibration preventing image sensing module, which comprises a fixed seat, a movable platform arranged on the fixed seat and moving relative to the fixed seat along the first direction and the second direction, an image sensing unit arranged on the movable platform, and a driving unit. The driving unit comprises a first magnet and a second magnet arrangedon the fixed seat and a circuit board arranged on the movable platform, wherein the circuit board is printed with a first precise pattern coil and a second precise pattern coil, and the first and second precise pattern coils and the first and second magnets on the fixed seat produce relative motion by means of voltage signals input to the circuit board so as to inhibit or compensate the fuzzy image. Because the design for printing the coils on the circuit board is adopted, the integral thickness is effectively reduced.

Description

technical field [0001] The invention relates to an image sensing module, in particular to a miniaturized anti-hand shake image sensing module. Background technique [0002] General anti-shake digital cameras use sensing components to detect the movement of the floating image capture unit, and send voltage signals to make the image capture unit move at high speed in two dimensions on a plane perpendicular to the optical axis to suppress or correct In the process of shooting, blurred images due to vibration can achieve the effect of anti-shake. [0003] refer to figure 1 , an existing anti-hand vibration device 1 includes a fixed base 11, a horizontal moving platform 12 mounted on the fixed base 11 and displaced horizontally relative to the fixed base 11, mounted on the horizontal moving platform 12 and relatively A vertical moving platform 13 for vertical displacement, an image sensing unit 14 installed on the vertical moving platform 13 , and a driving unit 15 .

Problems solved by technology

However, since the positioning unit 16 utilizes the transmission cam 161 to connect the motor and the positioning platen 162, the volume occupied by the positioning unit 16 as a whole is difficult to reduce, and the volume of the camera equipped with the anti-shake device 1 increases.

[0008] In addition, since the pair of vertical and horizontal driving coils 153 and 154 have many stacked layers and use a large amount of copper, heat will easily accumulate and cause a temperature difference effect of copper materials, that is, the difference in resistance value will be increased, so that the pair of vertical and horizontal driving coils 153, 154 154 cannot effectively dissipate heat at high temperatures, which in turn affects the relative displacement between the vertical and horizontal moving platforms 13, 12 and the fixed seat 11

[0009] As can be seen from the above, since the pair of vertical and horizontal drive coils 153, 154 are wound with traditional copper wires, they occupy a certain thickness. In addition, the positioning unit 16 uses the transmission cam 161, which increases the difficulty of thinning the camera. Therefore, manufacturing a small and thin anti-hand vibration device 1 has always been the research and development focus of related companies.
