An apparatus for attaching LED chips, comprising:
- a worktable;
- a plurality of holders mounted on the worktable;
- a plurality of wires including a plurality of first wires and a plurality of second wires, a plurality of first wire segments of each of the first wires wind around each of the holders at a predetermined interval along a longitudinal direction of each of the holders, and a plurality of second wire segments of each of the second wires wind around each of the holders at the predetermined interval along the longitudinal direction of each of the holders;
- an image capturing device disposed above the worktable and configured to capture an image of the worktable;
- a plurality of LED chips attached across the first wire and the second wire on the corresponding holder, where a predetermined distance between the first wire and the second wire depends on sizes of the LED chips;
- an electronic device connected to the image capturing device and configured to provide for inputting the number of the LED chips to be attached across the first wire and the second wire on each of the holders, the electronic device is configured to display the image, and analyze, store and display coordinate positions of the two first wire segments of the first wire that are closest to either sides of each of the holders respectively and the two second wire segments of the second wire that are closest to the either sides of the holder respectively according to a position of capturing the image by the image capturing device, the electronic device is configured to analyze coordinate positions of the LED chips to be attached according to the coordinate positions, the predetermined interval, the predetermined distance and the number of the LED chips;
- and
- an attaching device connected to the electronic device and configured to attach the LED chips across the first wire and the second wire according to the coordinate positions.
A method for attaching LED chips, comprising the following steps:
- winding first wire segments of a first wire around each of holders at a predetermined interval along a longitudinal direction of each of the holders, and second wire segments of a second wire around each of the holders at the predetermined interval along the longitudinal direction of each of the holders, wherein a predetermined distance between each of the first wire segments and each of the adjacent second wire segments depends on a size of each of LED chips;
- mounting the holders on a worktable;
- using an image capturing device to capture an image of the worktable;
- storing and displaying the image of the holders, coordinate positions of the two first wire segments that are closest to either sides of each of the holders respectively, and coordinate positions of the two second wire segments that are closest to the either sides of each of the holders respectively by using an electronic device;
- inputting the number of the LED chips to be attached above a surface of each of the holders that faces an attaching device to the electronic device;
- using the electronic device to analyze coordinate positions of the LED chips to be attached across the first wire and the second wire on the holder, according to the coordinate positions of the two first wire segments and the two second wire segments that are closest to the either sides of the holder, the predetermined interval, the predetermined distance and the number of the LED chips;
- and
- using the attaching device to attach the LED chips across the first wire and the second wire according to the coordinate positions of the LED chips.
