Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor laser coating, and in particular to a fixture, an assembly tool and an assembly method for clamping a laser bar. Background Art

[0002] Semiconductor lasers (LDs) have the advantages of small size, light weight, high conversion efficiency, and long service life. They are widely used in solid-state laser pumping, industrial processing, laser medical treatment, and military fields, and have very broad application prospects and market value. In the process of semiconductor laser chip production, end-face coating of laser bars is one of the most important process steps. A good coating effect can optimize the laser threshold current and emission efficiency, and ultimately achieve the maximum laser power output on a single side.

[0003] There are many types of existing bar-shaped semiconductor laser end face coating fixtures, which are used in the coating process. The main purpose is to clamp a certain number of chip carriers arranged in parallel. There are many problems with the existing fixtures, as follows:

[0004] 1. The fixture structure is not designed reasonably. When the fixture is installed on the coating furnace bracket, it is easy to fall off due to improper operation. At the same time, during the coating process, the active end of the fixture is clamped by the fixed end of the coating furnace bracket and cannot be effectively clamped, causing the workpiece to fall.

[0005] 2. It is difficult to assemble the product into the fixture. The movable end of the fixture needs to be pressed manually during operation, which requires high skills of personnel. As a result, the work efficiency is low, the success rate of strip installation is not high, and it is easy to cause product loss.

[0006] 3. The width or thickness of the clamping end of the product is fixed, and it cannot be adjusted accordingly for products of different widths or thicknesses. Especially for the thickness of the bar, if the width of the bar is smaller than the thickness of the clamping end, the product will be blocked by the clamping end during the coating process, resulting in uneven thickness of the coated film; on the contrary, if the width of the bar is much thicker than the thickness of the clamping end, it is easy to cause product warping, increase the gap between the products, and cause the coating film material to penetrate.

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0055] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0056] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0057] like Figures 1 to 5 As shown, it is a clamp of an embodiment of the present invention, which is used to clamp the laser bar 3. The laser bar 3 is relatively small, usually with a length of 5-10.8mm, a width of 1-3mm, and a thickness of 0.25-1mm. The clamping opening of the clamp is a V-shaped clamping opening 21, so the contact between the clamp and the end face of the laser bar 3 is a line contact, which can fully coat the laser bar 3, so that the laser bar 3 has a uniform coating thickness, and the thickness of the clamp is greater than the thickness of the laser bar 3, so the phenomenon of warping of the laser bar 3 can be avoided.

[0058] See also Figure 1-Figure 5The clamp of the embodiment of the present invention includes a fixed frame 10, a clamping plate 20 detachably connected to the fixed frame 10, and a fastener 30 for connecting the fixed frame 10 and the clamping plate 20. The fixed frame 10 is hollowed out in the middle. The fixed frame 10 includes a first fixed edge 11 and a second fixed edge 12. The first fixed edge 11 and the second fixed edge 12 are both provided with a slide groove 121. One end of the clamping plate 20 is installed on the first fixed edge 11, and the other end is installed on the second fixed edge 12. The fastener 30 passes through the slide groove 121 and is connected to the clamping plate 20, and the fastener 30 can slide along the slide groove 121, so that the clamping plate 20 can be fixed at different positions of the fixed frame 10. At least two clamping plates 20 are provided, and two adjacent clamping plates 20 are used to clamp the laser bar 3, and each clamping plate 20 is provided with a V-shaped clamping opening 21 on the side facing the other clamping plate 20, and the laser bar 3 is clamped in the V-shaped clamping opening 21 of the two adjacent clamping plates 20.

[0059] It can be understood that the slide groove 121 of the first fixed side 11 can be set as a long slide groove 121, or it can be composed of a plurality of short slide grooves 121. In order to facilitate the adjustment of the position of the clamping plate 20 and to limit the position of the clamping plate 20, the slide groove 121 of the embodiment of the present invention is composed of a plurality of short slide grooves 121. The length of each short slide groove 121 can be different, and it can be suitable for one clamping plate 20 or two clamping plates 20. It can also load the laser bar 3 to the maximum extent according to the laser bars 3 of different sizes. The slide groove 121 of the second fixed side 12 is set corresponding to the slide groove 121 of the first fixed side 11.

[0060] Optionally, threaded holes 22 are provided at both ends of the clamping plate 20, and the fasteners 30 are screws, which are adapted to the threaded holes 22. The clamping plate 20 and the fixed frame 10 are connected by screws, and the connection method is simple and reliable, and the adjustment is convenient.

The upper and lower surfaces of the laser bar 3 are suspended, and the V-shaped clamping opening 21 of the clamping plate 20 is in line contact with the laser bar 3, which does not affect the coating effect. In addition, clamping the laser bar 3 by the clamping plate 20 is safe and reliable, and can prevent the material source from being contaminated after falling off.

[0064] Furthermore, the fixing frame 10 can be flipped relative to the coating machine, so that double-sided coating of the laser bar 3 can be achieved.

[0065] The clamp of the embodiment of the present invention has the following advantages:

[0066] First, the hollowed-out area in the middle of the fixed frame 10 is used to place the clamp 20 with the laser bar 3, so that the laser bar 3 is unobstructed on both sides. Therefore, the clamp is suitable for any type of coating machine, and can achieve double-sided coating in one installation, thereby reducing secondary damage to the product.

[0067] Second, the clamping opening of the clamping plate 20 is a V-shaped clamping opening 21, so the contact between the clamp and the end surface of the laser bar 3 is a line contact, which can fully coat the laser bar 3, so that the laser bar 3 has a uniform coating thickness.

[0068] Thirdly, the clamping opening of the clamping plate 20 is a V-shaped clamping opening 21 , so the thickness of the clamping plate 20 is greater than the thickness of the laser bar 3 , thereby preventing the laser bar 3 from warping.

[0069] Fourthly, the clamping opening of the clamping plate 20 is a V-shaped clamping opening 21 , so the clamping plate 20 can be suitable for laser bars 3 with different end face thicknesses.
