Problems solved by technology

However, there is a tolerance between the outer diameter of the pressure rod and the inner diameter of the lens barrel in the existing assembly jig, so it is impossible to ensure that the axis of the pressure rod is strictly aligned with the axis of the lens barrel, resulting in a force applied to the optical component when the pressure rod is pressed down Unevenness, causing the position of the optical components to tilt, affecting the imaging quality of the lens module

Embodiment Construction

[0011] Such as figure 1 As shown, the assembly jig 1 provided by the embodiment of the present invention includes a load plate 12 , a guide plate 14 , a pressure plate 16 , a plurality of guide posts 18 and a spring 19 . The guide plate 14 is disposed on the carrying plate 12 . The pressure plate 16 is parallel to the guide plate 14 and the bearing plate 12 and is connected through a guide column 18 covered with a spring 19 .

[0012] The carrying plate 12 is a rectangular flat plate, and the carrying plate 12 is provided with a plurality of accommodating grooves 120 for placing lens barrels (not shown in the figure). In this embodiment, the accommodating grooves 120 are arranged in a matrix on the carrier board 12 .

[0013] Please also refer to figure 2 , the guide plate 14 is a rectangular flat plate, and the guide plate 14 includes a top surface 140 and a bottom surface 142 parallel to and opposite to the top surface 140 . The bottom surface 142 defines a groove 144 c...

Abstract

The invention provides an assembling fixture. The assembling fixture comprises a bearing plate, a guide plate, a pressing plate, a guide post and a spring, wherein the bearing plate is provided with a plurality of holding grooves; the guide plate is arranged on the bearing plate and provided with a plurality of guide through holes corresponding to the holding grooves; the guide through holes are coaxial with the corresponding holding grooves; the pressing plate and the guide plate are opposite to each other in parallel and are connected through the guide post on which the spring is sleeved; the pressing plate comprises a pressing rod and a guide sleeve; the pressing rod is arranged on the pressing plate and corresponds to the holding groove; one end of the pressing rod is fixed on the pressing plate and the other end of the pressing rod is protruded out of the pressing plate and is opposite to the guide plate; the guide sleeve is sleeved on the pressing rod; the guide sleeve and the guide through holes are provided with matched guide conical surfaces respectively; and when the pressing plate presses down along the guide post, the guide conical surface on the guide sleeve is in tight fit with the guide conical surface of the guide through hole, so that the axis of the pressing rod is aligned with that of the holding groove.

Description

technical field [0001] The invention relates to an assembly fixture, in particular to an assembly fixture for assembling a lens module. Background technique [0002] During the assembly process of the lens module, usually a single pressing bar is used to press down the optical components in the lens barrel so that the optical components are placed flat. However, there is a tolerance between the outer diameter of the pressure rod and the inner diameter of the lens barrel in the existing assembly jig, so it is impossible to ensure that the axis of the pressure rod is strictly aligned with the axis of the lens barrel, resulting in a force applied to the optical component when the pressure rod is pressed down Unevenness causes the position of the optical components to tilt, which affects the imaging quality of the lens module. Contents of the invention [0003] In view of this, it is necessary to provide an assembly jig that can precisely align the axis of the pressing rod an...
