Method of manufacturing suspension support devices
A method of manufacturing suspension devices comprising the steps of: a) forming an integral elastic sheet, the elastic sheet having first and second suspension devices, each suspension device being provided with attachment parts configured to be fixed to a movable object, fixing parts configured to be fixed to a base, and elastic parts connected between the attachment parts and the fixing parts respectively and configured to bias the object relative to the base, the elastic parts of the suspension devices being alternately distributed; b) separating the first and second suspension devices from each other before being attached to the object.
1. A method of manufacturing suspension devices comprising the steps of:
a) forming an integral elastic sheet, the elastic sheet having first and second suspension devices, each suspension device being provided with attachment parts configured to be fixed to a movable object, fixing parts configured to be fixed to a base, and elastic parts connected between the attachment parts and the fixing parts respectively and configured to bias the object relative to the base, the elastic parts of the suspension devices being alternately distributed;
b) separating the first and second suspension devices from each other, the separated suspension devices each being a single item before being attached to the object.
2. The method of claim 1 , including etching a sheet of resilient material to form the elastic sheet.
3. The method of claim 1 , wherein the elastic sheet comprises a frame connected with the suspension devices, the method further includes separating the first suspension device from the frame before it is fixed to the object, and separating the second suspension device from the frame after it is fixed to the object.
4. The method of claim 3 , wherein during separating of the suspension devices, the attachment parts of said first suspension device are kept directly connected together, and the attachment parts of the second suspension device are separated from each other.
5. The method of claim 1 , wherein before the step of separating, the attachment parts of the suspension devices are connected together.
6. The method of claim 5 , wherein the attachment parts are distributed along a substantially circular path, each elastic part comprises a plurality of circumferential extending parts extending in a circumferential direction of the circle and radially spaced, corner parts connecting adjacent circumferential extending parts, and radially extending parts extending in a radial direction of the circle to connect the attachment part and the fixing part to the circumferential extending parts.
7. The method of claim 1 , wherein the first and second suspension device comprises a plurality of separate sections each comprising one of the attachment parts, one of the elastic parts and one of the fixing parts, the method including using a sub-frame to connect together the attachment parts of the first suspension device after it is separated from the elastic sheet, and removing the sub-frame after the first suspension device is attached to the object.
8. The method of claim 7 , including connecting the sub-frame to the attachment parts of the second suspension device in the elastic sheet and severing the connection between the sub-frame and the attachment parts of the second suspension device when separating the first suspension device from the elastic sheet.
9. The method of claim 3 , including connecting the frame with the suspension devices via necked connection points.
10. The method of claim 8 , including connecting the sub-frame with the suspension devices via necked connection points.
11. The method of claim 1 , wherein the object is a lens holder, and the method includes attaching the attachment parts of a first one of the suspension devices to a first end of the lens holder and attaching the attachment parts of a second one of the suspension devices to a second end of the lens holder.
