Embodiment Construction

[0036] The drawing shows a schematic representation of the seven steps 100 to 700 of the method according to the invention in cross-section for producing the joint assembly 800 according to the invention. The pin 1 is the location of the first part 1 a, eg the optical part to be positioned most precisely relative to the light source of the lighting device of the motor vehicle, and the second part 2 a has a cavity 2 for accommodating the pin 1 . In the example shown, the pin 1 is formed by a cone with a flat end 10 and the cavity 2 has a cylindrical volume, wherein matched pin-cavity combinations of different shapes are also suitable for the invention.

[0037] figure 1 The pin 1 is shown in the target position, the pin extending partially into the cavity 2 spaced a distance D between the bottom surface 20 of the cavity 2 and the facing end 10 of the pin 1 . Positioning 100 the pin 1 to this target position is the first step of the method according to the invention. In a cen...

Abstract

The invention relates to a method for partially joining a pin (1) of a first component (1a) to a second component (2a) having a cavity (2) by means of an adhesive (3) in order to fix the pin (1) in a target position which extends at least partially into the cavity (2) and is spaced apart by a distance (D) between a bottom surface (20) of the cavity (2) and a facing end (10) of the pin (1), the method comprises at least the following steps: positioning (100) the pin (1) to a target position; determining (200) a distance (D) between the bottom surface (20) of the cavity (2) and the facing end (10) of the pin (1) in the target position; removing (300) the pin (1) from the cavity (2); applying (400) a rigid spacer (4) on the bottom surface (20) of the cavity (2), the thickness (40) of said rigid spacer (4) being equal to the distance (D) between the bottom surface (20) of the cavity (2) and the facing end (10) of the pin (1) in the target position; filling (500) an adhesive (3) into the cavity (2) onto the rigid spacer (4); repositioning (600) the pin (1) to a target position; the adhesive (3) is cured (700) and a joint is obtained between the pin (1) and the second component (2a).

Description

technical field [0001] The present invention relates to a method of joining, by adhesive, a pin region of a first part to a second part having a cavity in order to secure the pin at least partially extending into the cavity and at the bottom surface of the cavity with the The facing ends of the pins are spaced apart by a distance in the target position. The invention also relates to a corresponding engagement assembly. Background technique [0002] The precise adjustment of light sources and optical components (eg lenses, reflectors or optical waveguides) relative to each other is a key challenge when assembling lighting devices for motor vehicles. During the mounting of the light source group and / or associated optics on a carrier (eg a platform or holder) of the lighting device, their relative positions are changed by the manipulator while the light source is operated and the resulting lighting effect is monitored. Then, the target position of the part is finally defined ...
