Description

Technical Field

[0001] The present invention belongs to the technical field of gyroscope manufacturing, and more specifically, relates to a lead trimming device for active devices and a method for using the same. Background Art

[0002] In the prior art, gyroscopes are becoming more and more miniaturized, but the lead lengths of active devices such as waveguide devices with pins, 6-pin light source devices, 8-pin light source devices, 14-pin pump lasers, etc. still remain at the standard lengths at the time of factory shipment without length change; it should be noted that an active device includes an active device body, and optical fibers with a preset length are respectively provided on both sides in the length direction of the active device body, and pins for connecting to a circuit board are respectively provided on both sides of the short side of the active device body. However, if the lead lengths of the active devices need to adapt to the spatial diversity and miniaturization trend of the gyroscope, lead trimming must be performed.

[0003] The connection between the root of the lead of the active device and the housing is sealed with a glass insulator, which undertakes the functions of airtightness and insulation; the inner end of the light source lead of the active device is connected to each component inside the housing with a metal wire or a semiconductor ball.

[0004] Currently, the leads of active devices are trimmed by the method of trimming while suspended. During the trimming process, shear stress is easily introduced at the root of the leads of the active device, and the stress is conducted into the leads; although partial lead trimming uses pin crimping and cutting, it is found through simulation that stress still conducts into the leads during the stress conduction path; there is a risk of peeling and fragmentation between the glass insulator and the leads and the housing during the stress conduction process.

[0005] The current technical situation of lead trimming for active devices: in different application scenarios, there are requirements for lead length changes of active devices. First, length markings need to be made on the leads, and then the excess leads are cut off at the marked points with a flat-nose pliers; this operation has defects: the lead length needs to be measured and marked once, and the flat-nose pliers are used for cutting. During the lead trimming process, shear stress is easily introduced at the root of the leads, and the stress is conducted into the leads; there is a risk of peeling and fragmentation between the glass insulator and the leads and the housing during the stress conduction process.

[0037] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0038] A lead trimming device for an active device according to an embodiment of the present application, as Figures 1 - 6 shown, which includes: a bottom plate 1 for support;

[0039] A first tooling unit 2 detachably connected to the bottom plate 1;

[0040] A second tooling unit 3 detachably connected to the first tooling unit 2. The second tooling unit 3 is used for fixing the active device 4 to facilitate the trimming of the pins of the active device 4. It should be noted that the active device 4 is a device such as a waveguide device with pins, a 6-pin light source device, an 8-pin light source device, or a 14-pin pump source laser, etc., which is prior art and will not be elaborated here;

[0041] A shearing unit 5 movably connected to the bottom plate 1, which trims the pins of the active device 4 fixed on the second tooling unit 3 to a preset length.

[0042] In one embodiment, the first tooling unit 2 includes a first tooling base 21. On both sides of the first tooling base 21, a first carrying platform 22 and a second carrying platform 23 are respectively formed. The upper surfaces of the first carrying platform 22 and the second carrying platform 23 are respectively flush with the upper surface of the first tooling base 21. A first installation groove 24 is formed between the first carrying platform 22 and the first tooling base 21, and a second installation groove 25 is formed between the second carrying platform 23 and the first tooling base 21. Installation holes 26 are respectively formed in the first installation groove 24 and the second installation groove 25. The installation holes 26 are strip-shaped. The installation holes 26 of the first tooling base 21 are detachably connected to the bottom plate 1 through first fasteners 27. The first installation groove 24 and the second installation groove 25 are symmetrically arranged with the center of the first tooling base 21 as the center. The first carrying platform 22 and the second carrying platform 23 are used for carrying the second tooling unit 3.

[0043] In one embodiment, as Figures 1 - 2 shown, it further includes a baffle 28. The baffle 28 is detachably connected to the side of the first tooling unit 2. The baffle 28 blocks the optical fiber of the active device 4 to prevent misoperation.

[0044] In one embodiment, as Figures 3 - 6As shown, the second tooling unit 3 includes a second tooling base 31 and a second tooling upper cover 32 that cooperates with the second tooling base 31. A first connection groove 311 for cooperating and connecting with the active device 4 is formed on the second tooling base 31, and a second connection groove 321 for cooperating and connecting with the active device 4 is formed on the second tooling upper cover 32. When the second tooling upper cover 32 cooperates with the second tooling base 31, the second connection groove 321 cooperates with the first connection groove 311 to fix the active device 4; both the first connection groove 311 and the second connection groove 321 are through-groove-shaped to facilitate the passing of the optical fiber of the active device 4; a plurality of first pin slots 312 are provided on the long side of the second tooling base 31, and a plurality of second pin slots 322 that cooperate with the first pin slots 312 are provided on the long side of the second tooling upper cover 32. When the second tooling upper cover 32 cooperates with the second tooling base 31, the second pin slots 322 cooperate with the corresponding first pin slots 312 to form fixing holes for fixing the corresponding pins of the active device 4, and the corresponding pins of the active device 4 are exposed outside the second tooling unit 3.

[0045] In one embodiment, as Figures 3 - 6 shown, one end of the second tooling base 31 forms a first fiber coiling area 34, and / or the other end of the second tooling base 31 forms a second fiber coiling area 35. The structure of the second fiber coiling area 35 is symmetrical to the structure of the first fiber coiling area 34; a coil groove 221 for placing the corresponding optical fiber of the active device 4 is formed on the first fiber coiling area 34, and an entrance coil table 222 for facilitating the corresponding optical fiber of the active device 4 to enter the coil groove 221 is formed on the first fiber coiling area 34. The entrance coil table 222 is higher than the bottom of the entrance coil groove 221 and lower than the surface of the first fiber coiling area 34. In this way, it is convenient for the corresponding optical fiber of the active device 4 to be temporarily stored in the corresponding fiber coiling area; the joints between the entrance coil table 222 and the coil groove 221, between the entrance coil table 222 and the first fiber coiling area 34, and between the coil groove 221 and the first fiber coiling area 34 are all chamfered with 0.5 mm to prevent damage to the optical fiber.

[0046] As an example, according to the type of the active device 4, the number of fiber coiling areas is different. As Figure 3 and Figure 4 shown, the active device 4 is a waveguide device with pins, and the left and right ends of the second tooling base 31 are respectively provided with a first fiber coiling area 34 and a second fiber coiling area 35; as Figure 5 and Figure 6 shown, the active device 4 is a light source device, and one end of the second tooling base 31 is provided with a first fiber coiling area 34; such layouts are common design means in the art and will not be elaborated.

[0047] In this embodiment, there are multiple specifications for the length of the pin slots formed between the second pin slots 322 and the corresponding first pin slots 312, corresponding to the pins of active devices of different models, such as 2.5 mm, 3 mm, and 3.5 mm, which are suitable for the small space requirements on existing gyroscopes and eliminate the need for pin length measurement.

[0048] In one embodiment, as Figure 3 and Figure 5 shown, the upper cover 32 of the second tooling is detachably connected to the base 31 of the second tooling through the second fastener 33. When installing the active device 4, the upper cover 32 of the second tooling and the base 31 of the second tooling are in a separated state. First, the lower part of the housing of the active device 4 is fitted with the first connection groove 311, and the optical fiber of the active device 4 is wound around the corresponding fiber coiling area. Then, the upper cover 32 of the second tooling is connected to the base 31 of the second tooling and is fitted with the upper part of the housing of the active device 4 through the second connection groove 321, so that the active device 4 is fixed by the upper cover 32 of the second tooling and the base 31 of the second tooling. Then, the upper cover 32 of the second tooling and the base 31 of the second tooling are locked through the second fastener 33 to ensure that the active device 4 is fixed on the second tooling unit 3. At this time, the pins of the active device 4 are in the preset pin slots.

[0049] In one embodiment, as Figure 2 、 Figure 4 and Figure 6 shown, in order to make the connection between the first tooling unit 2 and the second tooling unit 3 more convenient, a limiting protrusion 211 is formed on the first tooling base 21 of the first tooling unit 2, and the limiting protrusion 211 is strip-shaped; one or more limiting grooves 313 that cooperate with the limiting protrusion 211 are provided at the bottom of the second tooling base 31 of the second tooling unit 3. When the second tooling unit 3 is connected to the first tooling unit 2, the corresponding limiting grooves 313 cooperate with the limiting protrusion 211, which is convenient; there are multiple limiting grooves 313, and different positions of the limiting grooves 313 represent different positions of the pin slots, which facilitates the pin slots at different positions to be under the shearing unit 5, resulting in a better shearing effect.

[0050] In one embodiment, as Figures 1 - 2As shown, the pins of the active device 4 after leaving the factory are generally 10 mm in length. However, during installation, the pins of the active device 4 generally only need to be 2.5 mm, 3 mm or 3.5 mm. Therefore, the pins of the active device 4 after leaving the factory need to be sheared. The shearing unit 5 includes a support 51 connected to the bottom plate 1. The upper part of the support 51 is movably connected with a downward pressing connection block 52. One end of the downward pressing connection block 52 is movably connected to the upper part of the support 51 through a rotating shaft, and the downward pressing connection block 52 can swing downward relative to the support 51. For the convenience of operation, an operation handle 53 is detachably connected to the other end of the downward pressing connection block 52. A downward pressing convex part 54 is formed on the downward pressing connection block 52, and the downward pressing convex part 54 faces the bottom plate 1, and the downward pressing convex part 54 increases the downward pressing stroke.

[0051] The shearing unit 5 further includes a cutter 55. The cutter 55 is movably connected to the bottom plate 1. The cutter 55 is located below the downward pressing connection block 52, and the cutter 55 is located on the side of the second tooling unit 3. During operation, the downward pressing connection block 52 presses down on the cutter 55, and the cutter 55 shears the pins of the active device 4 on the second tooling unit 3. As an example, the downward pressing convex part 54 performs a downward pressing action on the cutter 55.

[0052] In one embodiment, as Figures 1 - 2 shown, an elastic unit 6 is further included. The cutter 55 is connected to the bottom plate 1 through the elastic unit 6. The elastic unit 6 includes guide posts 61 connected to the bottom plate 1. There are two groups of guide posts 61, and the two groups of guide posts 61 are arranged at intervals. A first elastic member 62 is sleeved on the guide post 61. As an example, the first elastic member 62 is a spring. A connection block 63 is movably connected to the guide post 61. The two ends of the connection block 63 are respectively movably connected to the corresponding guide posts 61. The first elastic member 62 is located between the bottom plate 1 and the connection block 63, and the connection block 63 squeezes the first elastic member 62. The cutter 55 is connected to the connection block 63. During the shearing process, the downward pressing connection block 52 overcomes the elastic force of the first elastic member 62.

[0053] In one embodiment, as Figures 1 - 2 shown, a pressing foot 64 is further included. The pressing foot 64 is connected to the connection block 63 through a second elastic member. The pressing foot 64 presses on the second tooling unit 3 to make the second tooling unit 3 more stable during the shearing process. During operation, when the shearing unit 5 presses down, the pressing foot 64 first presses on the second tooling unit 3, and the cutter 55 continues to press down for the shearing action.

[0054] In one embodiment, as Figure 1 shown, a blanking through hole 11 is provided on the bottom plate 1. The blanking through hole 11 is located directly below the cutter 55 and is used for the sheared material to fall into the recycling bin.

[0055] The usage method of a pin-cutting device for an active device according to an embodiment of the present application is as follows:

[0056] Step S1, fixing the active device: Place the active device 4 in the second tooling unit 3 according to the required pin length.

[0057] Step S2, positioning: Connect the second tooling unit 3 fixed in Step S1 to the first tooling unit 2, and coil the pigtail of the active device 4 into a 5-cm small loop and place it in the corresponding fiber coiling area.

[0058] Step S3, pin cutting: After the second tooling unit 3 is fixed in place, press down the cutting unit 5, and the cutter of the cutting unit 5 cuts the pins downward along the side wall of the second tooling unit 3.

[0059] Step S4, post-treatment: After cutting, release the cutting unit 5, and the cutting unit 5 automatically bounces up under the action of the elastic unit 6 and leaves the second tooling unit 3; Take out the cut active device from the second tooling unit 3.

[0060] In this embodiment, the active device is placed on the second tooling unit. There are various specifications for the pin length formed between the second pin slot and the corresponding first pin slot on the second tooling unit, corresponding to the pins of different models of active devices, such as 2.5 mm, 3 mm, and 3.5 mm, which are suitable for the small space requirements on existing gyroscopes, and there is no need to measure the pin length anymore; The second tooling unit fastens the pins through the pin slots and further compresses them through the pressing feet, so that the pins of the active device are fixed firmly and stably. During the pin cutting process, the stress cannot be transmitted to the root of the pins, avoiding stress damage to the glass insulators at the root of the pins.
