Among them, the BOX device has a laser chip, TEC semiconductor refrigeration, etc., which need to be connected to the circuit by gold wire bonding. When performing gold wire bonding, an automatic wire bonding machine is required, such as shown in the patent document of publication number CN115084343A. The machine usually includes a workbench, a lower support block, a material strip, a pressure plate, a wire bonding device, and a material strip conveying mechanism. This method is conducive to mass production.

[0003] However, it is not suitable for the development and trial production stage of a small amount. When the object to be wired is a new solution, it is necessary not only to design a new material strip, but also to consider whether the old lower support block and the old pressure plate are compatible with the new material strip. If they are not compatible, a new pressure block or lower support block needs to be designed. Moreover, even if only a new material strip is designed, the technical operator often needs to re-adjust the machine to be compatible with the new material strip design. The adjustment process is usually very cumbersome and not suitable for rapid verification of multiple solutions.

[0004] Therefore, a new fixture is needed to address this scenario, saving technical operators’ time, improving verification speed, and accelerating development. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications 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.

[0030] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. 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 utility model.

[0031] The utility model proposes a feasible fixture for gold wire bonding of optical module BOX devices. The utility model combines the lower support block, material strip and pressing block in the prior art into one. The user only needs to put the device to be wired into the fixture, and then lock the BOX device, so that the BOX device and the fixture remain relatively still, and then put the entire fixture together with the BOX device into an automatic wire bonding machine.

[0032] Next, you only need to simply adjust the height of the automatic wire bonding machine base so that the wire bonding head of the machine can touch the BOX device and then you can focus on setting the automatic wire bonding path. The fixture has four slots and can hold four BOX devices at a time. Each slot has an independent fixing mechanism that can fix a single BOX device, which is convenient for debugging and testing during the product development stage.

[0033] Please refer to Figures 1 to 6 A preferred embodiment of the fixture for gold wire bonding of optical module BOX devices of the utility model comprises a base 1, at least two strip-shaped protrusions 2 are arranged in parallel on the front side of the base 1, at least one fixing position for fixing the BOX device 3 to be fixed is arranged between the two strip-shaped protrusions 2, and an adjustable fixing mechanism for fixing the BOX device 3 to be fixed at the fixing position is arranged on the strip-shaped protrusion 2.

[0034] This embodiment fixes the BOX device 3 to be fixed by a corresponding adjustable fixing mechanism, adopts a separate fixing strategy, and supports the fixing of a minimum single BOX device 3 to be fixed. The operation is flexible and suitable for verification or debugging operations.

[0035] As an implementation scheme, in this embodiment, the number of the strip-shaped protrusions 2 is three, and two fixing positions for fixing the BOX device 3 to be fixed are arranged between two adjacent strip-shaped protrusions 2. That is to say, in this embodiment, four fixing positions for fixing the BOX device 3 to be fixed are arranged on the base 1, and four BOX devices 3 can be installed at one time, and each fixing position has an independent adjustable fixing mechanism.

[0036] Furthermore, in this embodiment, the adjustable fixing mechanism includes a slider 4 and a fixed block 5, a slide groove 6 for installing the slider 4 is provided on the strip protrusion 2, the fixed block 5 is fixedly arranged at the top of the slide groove 6, and the fixed block 5 and the slider 4 are adjustably connected by a hexagon socket hand screw 7.

[0037] The sliding groove 6 and the slider 4 have a large aspect ratio, which significantly inhibits the rotational freedom. It is not easy for the rotation of the hexagon socket thumb screw 7 to act on the slider 4 through friction, causing the slider 4 to rotate, thereby causing the bottom of the BOX device 3 to be fixed to be unable to fit tightly against the clamp, causing the BOX device 3 to deviate from the designed fixed position.

[0038] Among them, a protrusion block 8 is arranged at one end of the hexagon socket hand screw 7, and a groove 9 matching the protrusion block 8 is arranged at the top of the sliding block 4.

[0039] In this embodiment, the fixing block 5 is fixed to the top of the strip-shaped protrusion 2 by means of a hexagon socket M2 screw 11. The fixing block 5 is a rectangular parallelepiped, and a threaded through hole is provided in the middle.

[0040] In this embodiment, the base 1 is square and is made of 420F stainless steel.

[0041] The bottom of the base 1 has inclined surfaces on both sides, which are used for the automatic wire bonding machine to fix the clamp on the machine.

[0042] A threaded through hole 10 is provided near the edge of the base 1 for inserting a threaded rod so as to lift the clamp or place the clamp on a machine.

[0043] The structure and working principle of a preferred embodiment of the clamp for gold wire bonding of an optical module BOX device of the present invention are further described below.

[0044] In this embodiment, the main body of the base 1 is a rectangular structure made of 420F stainless steel. There are inclined surfaces on both sides of the bottom of the base 1, which are used for the automatic wire bonding machine to fix the clamp on the machine. There is a 3mm threaded through hole 10 near the edge of the base 1, which is used to insert a threaded rod to lift the clamp or place the clamp on the machine. There are four slide grooves 6 on the base 1, and the slider 4 is placed in the slide groove 6, so that the slider 4 can theoretically only have one degree of freedom and slide forward and backward in the specified direction. There are 8 M2 threaded blind holes on the side of the base 1.

[0045] The slider 4 is irregular in shape, with a deep groove 9 inside, which can be connected to the raised block 8 of the customized hexagon socket thumb screw 7. After connection, assuming that the hexagon socket thumb screw 7 is fixed, the slider 4 has one rotational degree of freedom and one displacement degree of freedom. When the slider 4 is inserted into the slide groove 6, continuing to assume that the hexagon socket thumb screw 7 is fixed, the slider 4 is also fixed under ideal conditions and has no degree of freedom. At this time, the slider 4 and the hexagon socket thumb screw 7 can be regarded as a whole, and the sliding distance of the slider 4 can be controlled by manipulating the screwing depth of the hexagon socket thumb screw 7. When the slider 4 is still tightened after contacting the BOX device 3 to be fixed, the BOX device 3 can be fixed by friction, thereby achieving the purpose of locking the BOX device 3.

[0046] The fixing block 5 is a rectangular parallelepiped with a threaded through hole in the center for threaded connection with the hexagon socket hand screw 7. The fixing block 5 is fixed to the base 1 by the M2 hexagon socket screw and has no degree of freedom.

[0047] A total of eight hexagon socket M2 screws 11 are used to connect the fixing block 5 and the base 1 and completely fix them together.

[0048] The hexagon socket hand screw 7 is a custom screw, which is screwed into the threaded hole in the center of the fixing block 5 to limit it to two degrees of freedom, one rotational degree of freedom and one horizontal degree of freedom. The head of the hexagon socket hand screw 7 has a protrusion 8, which can be placed in the groove 9 in the slider 4. Since the slider 4 has only displacement freedom, the slider 4 has and only moves in the depth direction relative to the slide groove 6 on the base 1. The end of the hexagon socket hand screw 7 is designed with a hexagon socket hole that can be used for tightening with a hexagonal wrench.

[0049] The assembly process of this embodiment is as follows:

[0050] First, put the slider 4 into the slide groove 6 of the base 1, then screw the hexagon socket hand screw 7 into the fixed block 5, and then connect the hexagon socket hand screw 7 with the slider 4, and finally fix the fixed block 5 and the base 1 with the hexagon socket M2 screw 11.

[0051] When in use, the BOX device 3 to be fixed is placed into one of the four grooves 9 of the fixture, and the hexagon socket hand screw 7 corresponding to the groove is tightened until it can no longer be turned. At this time, the BOX device 3 to be fixed is fixed by friction.
