Handler comprising an acceleration device for testing electronic components
View Patent ↗The technology herein relates to a handler for testing electronic components, said handler comprising an acceleration device provided with a tappet which is linearly guided by means of at least one flat spring comprising two groups of spring arms, one group being fixed to the tappet and the other group to a frame which is stationary in relation to a housing of the movement generation device. Handler comprising an acceleration device for testing electronic components.
1. A handler for testing electronic components comprising a nest to receive the components and an acceleration device, by which components held in the nest are subjected to acceleration tests, wherein the acceleration device has a tappet, to which the nest can be fixed, as well as a movement generation device for accelerating the tappet in the axial direction, wherein the tappet is linearly guided by means of at least one flat spring, comprising two groups of spring arms, one group being fixed to the tappet and the other group to a frame which is stationary in relation to a housing of the movement generation device.
2. The handler as claimed in claim 1 , wherein each group comprises two to six, in particular three to five, spring arms.
3. The handler as claimed in claim 1 , wherein the spring arms extend at least substantially radially inwards from a circular closed peripheral area.
4. The handler as claimed in claim 3 , wherein the peripheral area is of annular form.
5. The handler as claimed in claim 1 , wherein the spring arms are arranged evenly distributed in the circumferential direction of the flat spring.
6. The handler as claimed in claim 1 , wherein the spring arms are formed in a straight-line.
7. The handler as claimed in claim 1 , wherein the spring arms are formed in a curve.
8. The handler as claimed in claim 7 , wherein the spring arms have an S-shaped curved section.
9. The handler as claimed in claim 8 , wherein the S-shaped curved sections of all spring arms are arranged in parallel.
10. The handler as claimed in claim 8 , wherein the S-shaped curved sections of one part of the spring arms, preferably half of all spring arms, are aligned running counter to the S-shaped curved sections of the other part of the spring arms.
11. The handler as claimed in claim 1 , wherein the spring arms are connected to the tappet and the frame at fixing places, which lie on a common circle.
12. The handler as claimed in claim 1 , wherein the tappet is linearly guided by means of at least two axially spaced flat springs.
13. The handler as claimed in claim 12 , wherein at least one first flat spring is arranged adjacent to the nest and at least one further flat spring adjacent to the movement generation device either on the same side as the first flat spring or beyond the movement generation device.
