Problems solved by technology

[0003] Existing optical positioning points generally adopt a circular appearance, and the size of the circle is determined by the size of the solder resist ink. In this design, there will be a problem of solder mask offset, which will lead to inaccurate positioning of the equipment, thereby af

Example Embodiment

[0022] Example 1:

[0023] See figure 1 , 2 , A fixture for attaching multiple laser chips, the surface of the substrate 1 is provided with a through hole 2, and an optical positioning point a3 is provided on the upper right side of the top surface of the substrate 1. The optical positioning point a3 is fixed on the substrate 1 by screws. 1 There is an optical positioning point b4 on the lower right side of the top surface. The optical positioning point b4 is fixed on the substrate 1 by screws. The optical positioning point a3 and the optical positioning point b4 are both "L"-shaped structures and are positioned through the "L"-shaped optical The point a3 and the optical positioning point b4 effectively prevent the reference position of the optical positioning point from shifting due to the ink offset, thereby effectively improving the accuracy and quality of the placement.

Example Embodiment

[0024] Example 2:

[0025] See image 3 , 4 , 5, a fixture for multiple laser chip placement, the upper left side of the through hole 2 is provided with a limit block a5, the limit block a5 is fixed on the substrate 1 by screws, and the bottom end of the limit block a5 is provided with a rubber layer 9. The rubber layer 9 is made of antistatic rubber. The right side of the rubber layer 9 is provided with a chamfer 8. The rubber layer 9 is fixed on the limit block a5 by glue, and the right side of the limit block a5 is provided with a limit block b6. b6 is fixed on the base plate 1 by screws, a spring block 7 is provided in the middle of the bottom end of the through hole 2, and the spring block 7 is fixed on the base plate 1 by screws. The limit block a5, the limit block b6 and the spring block 7 are all fixed on the base plate 1 The back of the spring block 7 is provided with a convex block 10 above the inside of the spring block 7. The convex block 10 is fixed in the spring blo...

Abstract

The invention discloses a clamp for mounting a plurality of laser chips. The clamp comprises a substrate and a spring block, a through hole is formed in the surface of the substrate, and an optical positioning point a is arranged above the right side of the top surface of the substrate. An optical positioning point b is arranged below the right side of the top surface of the substrate, and the optical positioning point a and the optical positioning point b are both L-shaped structures. A limiting block a is arranged above the left side of the through hole, a rubber layer is arranged at the bottom end of the limiting block a, and the rubber layer is made of anti-static rubber. A chamfer is arranged at the right side of the rubber layer, and through the chamfer, the surface of the chip can be prevented from being abraded during the chip clamping process. A limiting block b is arranged at the right side of the limiting block a, a spring block is arranged in the middle at the bottom end ofthe through hole, and the limiting block a, the limiting block b and the spring block are all fixed to the back of the substrate. A protruding block is arranged above the interior of the spring blockand can move up and down in the spring block, and a spring is arranged at the bottom end of the protruding block. The clamp has the advantages of being capable of clamping a plurality of chips, and being accurate in positioning and firm in clamping.

Description

technical field [0001] The invention relates to the technical field of chip mounting fixtures, in particular to a fixture for mounting multiple laser chip chips. Background technique [0002] With the progress of society and the development of economy, semiconductor lasers are more and more widely used in medical and military fields due to their small size, light weight, and high electro-optical conversion efficiency. With the rapid development of the electronics industry, electronic products are miniaturized The trend is becoming more and more obvious, and it is widely used in various electronic products and large-scale equipment and devices. In order to meet the needs of automatic production and processing, it is necessary to add optical positioning points on the surface and bottom of the mounting board; [0003] Existing optical positioning points generally adopt a circular appearance, and the size of the circle is determined by the size of the solder resist ink. In this ...
