Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor laser chip packaging, in particular to a TO tube socket anti-pinching device for an automatic eutectic machine for semiconductor laser chips. Background Art

[0002] Semiconductor laser chips are core components of optical communications and various intelligent devices. Generally speaking, semiconductor laser chips must be packaged before they can be used, and TO packaging is a common method. TO packaging, also known as coaxial packaging, usually has a metal shell and has excellent performance of high speed and high thermal conductivity.

[0003] The automatic eutectic machine is a key equipment for TO packaging. During the SMD packaging of semiconductor laser chips, the automatic eutectic machine needs to use a fixture to clamp and fix the TO socket. When the specification of the TO socket is a pure gold-plated shell, such as a 0.07mm gold-plated layer, due to the soft hardness of gold material, if the fixture of the automatic eutectic machine is too tight, it is easy to clamp the gold-plated shell of the TO socket, and if it is too loose, it will not meet the positioning accuracy requirements.

[0004] The clamping solutions for automatic eutectic machines on the market have various specifications such as blade-shaped, semicircular, and circular, which have certain defects. The advantages of the blade-shaped clamp are simple structure, high positioning accuracy, and good dynamic characteristics. The disadvantage is that it is easy to leave two clamping marks on the gold-plated shell of the TO tube socket. The advantages of semicircular and circular clamps are that they are in contact with the TO tube socket surface, and the gold-plated shell of the TO tube socket is balanced and not easily clamped. However, the disadvantages are that they have high requirements for concentricity, it is difficult to ensure positioning accuracy, and the dynamic characteristics are poor.

[0005] The utility model with the publication number CN211428137U and the name of a TO tube socket positioning device is a compromise solution. In its technical solution, the positioning fixture and the tube socket have four contact points, which can not only ignore the concentricity, improve the positioning accuracy, but also increase the contact area, and better guarantee the dynamic characteristics. However, it does not improve the pinching problem of the gold-plated shell of the TO tube socket, and the two pinching marks of the blade-shaped clamp become four pinching marks. Taking the above utility model patent as an example, although it discloses a clamp device for optimizing the TO tube socket, it does not have the purpose of preventing pinching.

[0010] The first clamp arm and the second clamp arm have the same structure and are symmetrically installed in the same horizontal direction, and the first clamp arm and the second clamp arm clamp the TO tube socket;

[0012] As an improvement, the clamping base is driven by an electromechanical control device of the automatic eutectic machine.

[0013] As an improvement, the left clamping part and the right clamping part are rotatably connected to the clamping base via clamping part fixing rivets.

[0014] As an improvement, the left clamping portion and the right clamping portion of the first clamping arm and the second clamping arm can be in contact with the TO tube socket.

[0017] 3. Beneficial Effects

[0018] The advantages of the utility model compared with the prior art are:

[0019] 1. The contact surface is in contact with the gold-plated shell of the TO tube holder, and the contact area is large. Even if there is a certain degree of extrusion, no obvious pinch marks will be left;

[0020] 2.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 2 As shown, the prior art structure includes: a first blade-shaped clamp arm 300 and a second blade-shaped clamp arm 301. When clamping the TO tube holder 100, the contact surface with its gold-plated shell 101 is two lines. The technical problem caused is that if the clamping force is too large, two clamping marks will be left on the surface of the gold-plated shell 101. If the clamping force is too small, the clamping positioning accuracy will be reduced, affecting the subsequent operation accuracy of the eutectic machine.
