Description

Technical Field

[0001] This utility model relates to the field of optoelectronics, specifically to the field of lasers. Background Technology

[0002] After the TO (laser emitter) completes the chip mounting and wire bonding process, each TO needs to be inspected and photographed for record-keeping. The traditional method is to inspect and photograph each one separately, which is inefficient. Some manufacturers have invented a strip that can hold multiple TOs, but when using it, the strip needs to be laid flat to photograph the code on the side of the TO cap. At this time, the TO will fall off the strip, affecting the inspection efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a fixture for TO testing that is non-dropping, highly efficient and accurate.

[0004] To achieve the above objectives, this utility model provides a TO inspection and photographing fixture, comprising a strip capable of holding multiple TOs. The fixture further includes a strip fixing seat for securing the strip, the strip fixing seat having a accommodating cavity equal to the number of TOs placed on the strip, the upper part of which is a TO pin insertion cavity, and a magnet at the lower part of the accommodating cavity; multiple TO insertion holes are provided along the longitudinal direction of the strip, each insertion hole having a cap gripping groove along the transverse direction of the strip, and the side wall of the cap gripping groove having a protrusion that engages with the recess of the TO cap.

[0005] The material bar fixing seat has blocks on all four sides and inserts for inserting material bars at both ends.

[0006] After adopting the above solution, the TO is stuck in the fixing hole on the strip, the tube cap gripping groove exposes the code on the tube cap for easy photography, the protrusion on the side wall of the tube cap gripping groove positions the tube cap recess so that the tube cap will not rotate, and the magnet in the strip fixing seat attracts the metal tube foot so that the TO will not fall off, thus improving inspection efficiency.

[0009] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0010] Please see Figure 1 as well as Figure 2 , 3 This utility model discloses a TO inspection and photographing fixture, comprising a strip 2, a strip fixing base 1, a magnet 3, and a baffle 4. The strip 2 is inserted into the inserts 15 and 16 at both ends of the strip fixing base 1 through insertion holes 21 and 22 at both ends. Blocks 11, 12, 13, and 14 on all four sides of the strip fixing base 1 surround and fix the strip 2. The receiving cavity on the strip fixing base 1 communicates with the TO insertion hole 23 on the strip 2. The upper part of the receiving cavity of the strip fixing base 1 is a TO pin insertion cavity, and the lower part of the receiving cavity is provided with a magnet 3 for attracting the TO pins. Figure 2 As shown, the TO insertion hole 23 on the material bar 2 has a tube cap gripping groove 231 opened horizontally along the material bar to facilitate the gripping of the tube cap. The protrusion on the side wall of the tube cap gripping groove 231 positions the tube cap recess so that the tube cap will not rotate. At the same time, the opening of the tube cap gripping groove 231 exposes the tube cap coding area 52 for easy photography.

[0011] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent shape or structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
