Embodiment 1

[0032] Figure 1a It is a schematic structural diagram of a chip etching jig clamping a mother-son ring provided in Embodiment 1 of the present invention. Figure 1b for Figure 1a A cross-sectional view of the chip etch fixture along A1-A2 provided in . The chip corrosion fixture includes: a handle 1 and a clamping part 2 connected to the handle 1; the clamping part 2 includes an arc-shaped slot 21 and at least one fixing piece 22 located on the arc-shaped slot 21, the arc-shaped slot 21 cooperates with the fixing member 22 to fix the sub-ring 4 holding the chip 3 .

[0033] The shape of fixture 22 has multiple, for example, as Figure 1b As shown, the fixing piece 22 includes a first blocking piece 221 and a second blocking piece 222, and the first blocking piece 221 and the second blocking piece 222 are fixedly connected at a preset angle; Fitting, the second blocking piece 222 bears against the mother and child ring 4, which can effectively limit the movement of the moth...

Embodiment 2

[0040] Figure 2a It is a schematic structural diagram of a state in which a chip etching jig clamps a mother-child ring provided by Embodiment 2 of the present invention, Figure 2b It is a schematic structural diagram of a chip etching jig releasing a mother and son ring state provided by Embodiment 2 of the present invention, Figure 2c for Figure 2aA cross-sectional view of the chip etch fixture along B1-B2 provided in . Compared with the chip etching jig provided in Embodiment 1, the chip etching jig provided in this embodiment further includes an elastic element and a connecting rod in the clamping part, so that the worker can quickly clamp or release the female ring. Specifically, combined with Figure 2a , Figure 2b with Figure 2c As shown, the chip corrosion fixture includes: a handle 1 and a clamping part 2 connected to the handle 1; the clamping part 2 includes an arc-shaped slot 21 and at least one fixing piece 22 located on the arc-shaped slot 21, the arc ...

Embodiment 3

[0046] image 3 It is a schematic structural diagram of a chip etching jig clamping a sub-ring provided by Embodiment 3 of the present invention. Different from the chip etching jig provided in the second embodiment, the clamping part in the chip etching jig provided in this embodiment further includes a pick piece fixed on the connecting rod. Such as image 3 As shown, the chip corrosion fixture includes a handle 1 and a clamping part 2 connected to the handle 1; the clamping part 2 includes an arc-shaped slot 21 and at least one fixing piece 22 located on the side of the arc-shaped slot 21, and the arc-shaped slot The slot 21 cooperates with the fixing part 22 to fix the ring 4 with the chip 3 . The clamping part 2 further includes an elastic element 23 and a connecting rod 24 ; the elastic element 23 is connected to the arc-shaped slot 21 ; one end of the connecting rod 24 is connected to the elastic element 23 , and the other end is connected to the fixing member 22 . I...

Abstract

The embodiment of the invention discloses a chip corrosion clamp. The chip corrosion clamp comprises a handle and a clamping component connected with the handle; the clamping component comprises an arc-shaped clamping groove and at least one fixing part located on the arc-shaped clamping groove; and the arc-shaped clamping groove and the fixing parts cooperate to fix a child-mother ring. The chip corrosion clamp provided in the embodiment of the invention can help staff members to firmly hold a chip during the corrosion process of the chip, thereby preventing the chip from falling off and protecting the chip not to be scratched.

Description

technical field [0001] The invention relates to a light-emitting diode manufacturing technology, in particular to a chip etching jig. Background technique [0002] With the continuous development of light-emitting diode chip manufacturing industry, light-emitting diodes have been widely used in remote control, alarm and wireless communication. [0003] In the process of LED production, after the LED chip is diced, the side of the chip is ground very smooth by the blade of the dicing machine, so that the light emitted by the LED will continue to reflect inside it, causing most of the light to be lost The light output rate of the light-emitting diode (that is, the light efficiency of the light-emitting diode) is not high. In order to improve the light extraction rate of the light-emitting diode, it is necessary to corrode the sidewall of the light-emitting diode chip after dicing to make it rough. [0004] In the prior art, when corroding the side wall of the light-emitting ...
