Abstract
Abstract The invention relates to an apparatus for surface mounting of components (201) on a support (106). The arrangement comprises a positioning device )102, 103, 104) for holding and moving the components to a mounting position relative to the support. A centering arrangement of two components (203, 204) movable towards and from each other and disposed to center the component from opposite sides concurrently with its movement to the mounting position is provided. The centering arrangement (203, 204) comprises two centering electrodes (300, 310) which are designed with recesses (301, 302, 305, 306) which are adapted to the form and the size of the different component types to be mounted. The centering electrodes moreover comprise electric contact members (307, 308, 706) which are intended to connect the component to an equipment for measuring its electrical properties.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
108 words
An apparatus for surface mounting of components on a support, comprising a positioning device for holding and moving the components to a mounting position in relation to the support, whereby centering means are movable towards and away from each other and are arranged to center the component from opposite sides concurrently with its movement to the mounting position, characterized in that the centering means comprises two centering electrodes which are provided with recesses, the recesses having dimensions corresponding to dimensions of the components to be mounted, and that the centering electrodes comprise electrical contact members to connect the components to an equipment for measurement of its electrical properties.
Claim 2
Independent Claim
108 words
An apparatus for surface mounting of components on a support, comprising a positioning device for holding and moving the components to a mounting position in relation to the support, whereby centering means are movable towards and away from each other and are arranged to center the component from opposite sides concurrently with its movement to the mounting position, characterized in that the centering means comprises two centering electrodes which are provided with recesses, the recesses having dimensions corresponding to dimensions of the components to be mounted, and that the centering electrodes comprise electrical contact members to connect the components to an equipment for measurement of its electrical properties.
Claim 3
Dependent Claim
56 words
An apparatus according to claim 1, characterized in that the dimensions of the recesses of the centering electrodes correspond to dimensions of a component body, said body being introduced into the recess at the centering operation, and lateral surfaces of the electrodes facing each other being brought into contact with external connecting leads of the component.
Claim 4
Dependent Claim
48 words
An apparatus according to claim 1, characterized in that the component has a plurality of poles, and the centering electrodes are provided with contact surfaces for making contact with the poles of the component and with holes for those poles which are not connected to the contact members.
Claim 5
Dependent Claim
41 words
An apparatus according to claim 1, characterized in that the centering means comprises connecting electrodes having a form of resilient contact elements against which connecting leads of the component are brought into contact for measuring the electrical properties of the component.
Claim 6
Dependent Claim
48 words
An apparatus according to claim 4, characterized in that the connecting electrodes are disposed in opposed pairs with different numbers of contact tongues and/or different mutual distances between the contact tongues for each pair of electrodes, whereby the electrode pairs are arranged on different levels above each other.
