Description

Technical Field

[0001] The utility model belongs to the technical field of semiconductor device production equipment, and in particular relates to a universal optical fiber bracket clamping tool. Background Art

[0002] In the production process of butterfly-shaped semiconductor devices, after the optical fiber and the chip are coupled, the positions of the two need to be fixed by laser spot welding. The spot welding diagram is as follows Figure 1 .

[0003] Before spot welding, first pick up the fiber holder with tweezers and place it freely on the heat sink surface of the device. The optical fiber is located in the notch of the fiber holder. First, fix the fiber holder and the device heat sink by laser spot welding, and then fix the optical fiber and the fiber holder by laser spot welding. After spot welding, the position of the optical fiber and the chip is fixed.

[0004] The above spot welding process is also required in the production of semiconductor optoelectronic device distributed feedback laser (DFB), but an optical component used in DFB device - isolator (such as Figure 2 The optical fiber bracket itself is magnetic and will attract the optical fiber bracket, so that the optical fiber bracket cannot be freely placed in the required position. Figure 2 The placement of the optical fiber holder in the DFB manufacturing process is impossible because the optical fiber holder is adsorbed by the isolator and will flip and move, and it is impossible to fix it by spot welding.

[0005] At present, when DFB is manufactured, the bracket is clamped by manual hand-held tweezers and placed on the heat sink. However, the hand-held tweezers are unstable and prone to shaking and slipping, which affects the spot welding and even damages the optical fiber end face. The efficiency is low and the effect is very unsatisfactory. Therefore, a tool is needed to prevent the optical fiber bracket from being attracted by the isolator and to place it at the required position, which is the purpose of the utility model.

[0026] A universal optical fiber bracket clamping tool, such as Figure 3 As shown, it includes: a magnetic universal support 1 and a clamping claw component 2.

[0027] In one embodiment, Figure 4As shown, the magnetic universal support 1 comprises a magnetic base 1.1, a first connecting rod 1.2, a second connecting rod 1.3, a third connecting rod 1.4 and a handle 1.5; the magnetic base 1.1 and the first connecting rod 1.2 are connected by a ball hinge, the first connecting rod 1.2, the second connecting rod 1.3 and the third connecting rod 1.4 are connected by a ball hinge, and the handle 1.5 is installed at the connection between the first connecting rod 1.2 and the second connecting rod 1.3;

[0028] In one embodiment, Figure 5 As shown, the clamping jaw 2.3 component 2 includes a mounting plate 2.1, a handle 2.2, a clamping jaw 2.3, a positioning screw 2.4 and a compression spring 2.5; the clamping jaw 2.3 and the handle 2.2 are provided with two groups, and the clamping jaw 2.3 and the handle 2.2 in each group are connected with the handle 2.2 by a screw 2.4, and the positioning screw 2.4 passes through the holes on the two handles 2.2 and is connected with the mounting plate 2.1, and the compression spring 2.5 is placed in the holes of the two handles 2.2.

[0029] In one embodiment, Figure 5 As shown, the two handles 2.2 are axially rotated by means of positioning screws 2.4.

[0030] In one embodiment, Figure 5 As shown, the compression spring 2.5 presses against the handles 2.2 at both ends so that the two clamping jaws 2.3 are in a closed state.

[0031] In one embodiment, Figure 4 As shown, the clamping jaw 2.3 component 2 and the magnetic universal support 1 are clamped by a notch and are locked by a hand-tightening screw 2.4.

[0032] In one embodiment, Figure 4 As shown, the handle 1.5 adjusts the tightness of the ball hinge at the connection between the first connecting rod 1.2 and the second connecting rod 1.3 to adjust the universal support to achieve a suitable moving feel.

[0033] In one embodiment, Figure 4 As shown, a slider is provided on the mounting plate 2.1, a slide groove is provided at the end of the third connecting rod 1.4, and the mounting plate 2.1 is connected with the slide groove of the third connecting rod 1.4 through the slider.

[0034] Working principle: Figure 6As shown, when working, the magnetic base 1.1 can be fixed on the work surface by magnetic adsorption, and the tail of the handle 2.2 can be gently pressed by hand to open the clamping claw 2.3. The third connecting rod 1.4 can be moved by hand to move the end of the clamping claw 2.3 to a suitable position for clamping the optical fiber holder. After that, the handle 2.2 is released, and the clamping claw 2.3 is driven by the force of the compression spring 2.5 to clamp the optical fiber holder. The first connecting rod 1.2 connected to the magnetic universal support 1 is controlled by hand to move, and the optical fiber holder is placed on the device heat sink (such as Figure 6 ), the optical fiber is located in the groove of the optical fiber holder. Due to the fixing effect of the clamping claw 2.3, the optical fiber holder will no longer be adsorbed by the isolator and move, and the next step of spot welding can be carried out.

[0035] First laser spot weld point A (such as Figure 6 ), use your fingers to gently press the tails of the two handles 2.2 to open the two clamps 2.3, move the first connecting rod 1.2 on the magnetic base 1.1 to withdraw the clamps 2.3, at this time, since the optical fiber bracket has been spot-welded to the heat sink at point A, it will not move due to the adsorption of the isolator, and you can continue to spot-weld subsequent points.

[0036] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
