Description

Technical Field

[0001] This application relates to the field of mechanical jigs, specifically to a disassembly device. Background Technology

[0002] With the continuous development of the optical communication industry, especially as 5G gradually enters the large-scale deployment stage, the development of optical modules has also been driven. Since optical modules and optical devices account for an increasingly large proportion of the cost of communication networks, constraining the overall network cost, reducing the cost of optical modules and optical devices is a crucial goal for the optical communication industry. In the optical communication industry, reducing the production cost of optical devices is particularly important, starting with reducing material costs. Among material costs, material waste is particularly prominent, and controlling material waste has a profound impact on reducing the cost of optical devices.

[0003] After a certain period of use, optocouplers may experience partial damage, such as damage to the substrate or the transmitter, affecting the overall function of the optocoupler. Alternatively, during the manufacturing process, the precision requirements between the substrate and the transmitter during welding may not meet the corresponding quality standards. Generally, optocouplers with this problem are difficult to disassemble because the substrate and transmitter are fixed by welding. Summary of the Invention

[0004] This application provides a disassembly apparatus to improve the above-mentioned technical problems.

[0005] This application provides a disassembly device suitable for disassembling an optical coupling assembly. The optical coupling assembly includes a connected substrate and a transmitter, comprising: a positioning block, which has a groove and a fixing hole for fixing the substrate, wherein the extension direction of the groove is perpendicular to the axial direction of the fixing hole, and the fixing hole communicates with the groove; and a shearing plate, which is slidably disposed in the groove and has a shearing part for cutting the transmitter from the substrate.

[0006] In some embodiments, the positioning block includes a first inner wall located within a groove, a second inner wall and a connecting wall, the first inner wall and the second inner wall being disposed opposite to each other, the connecting wall being connected between the first inner wall and the second inner wall, and a fixing hole penetrating the connecting wall.

[0025] like Figure 1The optical coupling component 1 shown includes a connected substrate 10 and multiple transmitters 20. Each transmitter 20 typically includes an optical fiber, and the substrate 10 is generally an integrated lens or other structure. The transmitters 20 and substrate 10 are typically connected by welding on a welding plane 30. After a certain period of use, the optical coupling component 1 may experience partial damage, such as damage to the substrate 10 or a transmitter 20, affecting the overall function of the optical coupling component 1. Alternatively, during the manufacturing process, the precision requirements between the substrate 10 and transmitters 20 during welding may not meet the corresponding quality standards. Generally, for optical coupling components 1 with this problem, because the substrate 10 and transmitters 20 are fixed by welding and are inconvenient to separate, they are usually replaced as a whole or otherwise treated. This results in higher costs for the optical coupling component 1 during use or production.

[0026] Therefore, this application proposes a disassembly device 2 to improve the above-mentioned problems.

[0027] Please see Figure 2 This application proposes a disassembly device 2, including a positioning block 21 and a shearing plate 22. The positioning block 21 and the shearing plate 22 cooperate to separate the substrate 10 and the transmitter 20 by shearing.

[0028] The positioning block 21 is used to fix the optical coupling component 1 and plays a positioning role during the disassembly of the optical coupling component 1. The positioning block 21 can be made of a single piece of metal or it can be composed of multiple parts; no limitation is made here. For examples, please refer to [the relevant documentation]. Figure 3 A fixing hole 211 is provided on the positioning block 21. The transmitter 20 that needs to be disassembled on the optical coupling component 1 passes through the fixing hole 211 to fix the optical coupling component 1.

[0029] The welding plane 30 between the substrate 10 and the transmitter 20 may interfere with the shape of the substrate 10 itself, or with other transmitters 20 on the substrate 10 that do not need to be disassembled (such as...). Figure 1As shown, during the shearing process of the transmitter 20 along the welding plane 30 using shearing or other methods, the base 10 or other transmitters 20 may be damaged. Therefore, in some embodiments, the fixing hole 211 may include a first hole portion 2111 and a second hole portion 2112 that are connected. The shape of the first hole portion 2111 may be the same as the contour of part of the base 10, which is suitable for passing through the base 10 during use. The second hole portion 2112 is used to pass through the transmitter 20 that needs to be disassembled. After the transmitter 20 that needs to be disassembled passes through the second hole portion 2112, the part that passes through is sheared by the shearing plate 22. In other embodiments, the welding plane 30 between the base 10 and the transmitter 20 may not interfere with the shape of the base 10, so the fixing hole 211 may only include the first hole portion 2111, and the shearing of the welding plane 30 can be achieved even if only the transmitter 20 passes through the first hole portion 2111.

[0030] Positioning the transmitter 20 solely through the fixing hole 211 may cause it to slide along the fixing hole 211. Therefore, in some embodiments, the disassembly device 2 further includes a boss 23. The boss 23 can be fitted into the second hole 2112. In this embodiment, please refer again to... Figure 3 The substrate 10 also has a protruding portion near the optical coupling assembly 1. When the transmitter 20 is inserted into the second hole 2112 and positioned appropriately, the substrate 10 can abut against the boss 23. After the substrate 10 abuts against the boss 23, the transmitter 20 can no longer be inserted, thus positioning the optical coupling assembly 1 so that the shearing position of the shearing plate 22 can be accurately located on the welding plane 30. In some embodiments, the positioning block 21 is also provided with a positioning hole 217, which is located on the side of the first hole 2111 away from the second hole 2112, so that the transmitter 20, which does not need to be disassembled, can pass through the positioning hole 217 and also serve to position the optical coupling assembly 1.

[0031] Please refer to it again. Figure 2 The positioning block 21 cooperates with the shearing plate 22 to separate the transmitter 20 from the substrate 10 from the welding plane 30 by shearing. In this embodiment, the positioning block 21 is provided with a groove 212, the extension direction of which is perpendicular to the axial direction of the fixing hole 211. The shearing plate 22 is slidably disposed in the groove 212. During the sliding process of the shearing plate 22 in the groove 212, it cuts the optical coupling component 1.

[0032] For example, as one implementation, the positioning block 21 can be integrally formed from a single piece of metal, with a groove 212 formed on its surface. In other implementations, the positioning block 21 can also be assembled from multiple components, which is not limited here. The fixing hole 211 connects to the groove 212. When the reflective end passes through the fixing hole 211, it interferes with the sliding trajectory of the shear plate 22. Please refer to [link / reference]. Figure 5 As the shear plate 22 slides relative to the positioning block 21, the shear plate 22 abuts against the launching end 20 and provides a pushing force F1 to the launching end 20. Since the base 10 is located in the fixing hole 211, it cannot move along the direction of movement of the shear plate 22 under the push of F1. According to Newton's third law, the positioning block 21 provides a force F2 to the base 10 at this time. Since F1 and F2 are in opposite directions and are located on both sides of the welding plane 30, the launching end 20 and the base 10 separate along the weakest welding plane 30 under the action of F1 and F2.

[0033] For details, please refer to the following document again. Figure 2 The positioning block 21 may include a first inner wall 213, a second inner wall 214, and a connecting wall 215 located within the groove 212. The first inner wall 213 and the second inner wall 214 are disposed opposite to each other, and the connecting wall 215 connects the first inner wall 213 and the second inner wall 214. A fixing hole 211 penetrates the connecting wall 215. The first inner wall 213, the second inner wall 214, and the connecting wall 215 together form the groove 212. In one embodiment, the fixing hole 211 may penetrate the connecting wall 215, and during the shearing process, the welding plane 30 on the optical coupling assembly 1 is approximately parallel to the surface of the connecting wall 215. In other embodiments, the fixing hole 211 may also penetrate the first connecting wall 215 or the second connecting wall 215 to accommodate optical coupling assemblies 1 of different shapes.

[0034] In this embodiment, to prevent the shear plate 22 from deviating in the sliding direction during the sliding process, guide grooves 2131 can be provided on the first inner wall 213 and the second inner wall 214. Specifically, the extending direction of the guide grooves 2131 is parallel to the movement direction of the shear plate 22, and the two ends of the shear plate 22 that are far apart from each other are respectively embedded in the guide grooves 2131 on the first inner wall 213 and the second inner wall 214, and slide along the guide grooves 2131, thereby guiding the movement of the shear plate 22.

[0035] The shear plate 22 can be made of a metal material with high hardness, such as chromium-molybdenum steel or high-speed steel, which can increase the service life of the shear plate 22. The shear plate 22 is provided with a shearing part 221, which is used to cut the transmitter 20 from the base 10.

[0036] As an example, the shearing portion 221 is formed with a cutting edge. Specifically, the cutting edge is located at the edge of the shearing portion 221, and the thickness of the shearing plate 22 is thinner closer to the edge, with the cutting edge formed at the outermost edge. When the shearing plate 22 slides along the groove 212, the cutting edge slides against the connecting wall 215 until it abuts against the optical coupling assembly 1. The cutting edge applies pressure to the optical coupling assembly 1 to separate the emitting end 20 from the substrate 10.

[0037] In some embodiments, to prevent the cutting edge from cutting into unwanted areas of the optocoupler 1, a clearance groove 2211 is provided on the cutting edge. The specific shape of the clearance groove 2211 is related to the shape of the optocoupler 1 being cut. The clearance groove 2211 can protect parts of the optocoupler 1 from being cut by the cutting edge during the sliding of the shearing plate 22.

[0038] To drive the relative movement between the shearing plate 22 and the positioning block 21, in one embodiment, the disassembly device 2 may further include an upper mounting plate 23 and a lower mounting plate 24. The upper mounting plate 23 and the lower mounting plate 24 may be disposed between a driving device, such as a hydraulic device or other driving device, which is used to drive the relative movement between the shearing plate 22 and the positioning block 21. For example, the upper mounting plate 23 may be disposed at the end of the shearing plate 22 away from the positioning block 21, and the lower mounting plate 24 may be disposed at the end of the positioning block 21 away from the shearing plate 22. The relative movement between the upper and lower mounting plates 24 can drive the relative sliding between the shearing plate 22 and the positioning block 21.

[0039] In some embodiments, fixing bolts 231 are also provided on the upper mounting plate 23 and the lower mounting plate 24. The fixing bolts 231 are used to connect to the drive device. The fixing bolts 231 may be welded to the upper mounting plate 23 and the lower mounting plate 24, or they may be threaded onto the upper mounting plate 23 or the lower mounting plate 24, which is not limited here.

[0040] In some cases, simply providing the guide groove 2131 is insufficient to completely guide the sliding of the shearing plate 22 during disassembly. Therefore, in some embodiments, the relative movement between the shearing plate 22 and the positioning block 21 can also be guided by providing the guide hole 216 and the guide post 231. For example, the positioning block 21 has a guide hole 216, the axis of which extends parallel to the extension direction of the groove 212. The positioning post is mounted on the upper mounting plate 23. Specifically, one end of the positioning post is connected to the upper mounting plate 23, and the other end slides into the guide hole 216. Since the upper mounting plate 23 is fixedly mounted on the shearing plate 22, the sliding of the positioning post in the guide hole 216 can guide the sliding between the shearing plate 22 and the positioning block 21. The accuracy of the guidance is determined by the fitting accuracy between the positioning post and the guide hole 216. In this embodiment, a clearance fit can be used between the positioning post and the guide hole 216 to achieve a high fitting accuracy between the guide hole 216 and the guide post 231. The specific fitting accuracy between the guide hole 216 and the guide post 231 is not limited here.

[0041] In this embodiment, to further improve the sliding accuracy between the shear plate 22 and the positioning block 21, the number of guide holes 216 and guide posts 231 can be greater than one. In this embodiment, two guide holes and two guide posts 231 are provided. The two guide holes are located on both sides of the slide groove 212 and are close to the first inner wall 213 and the second inner wall 214, respectively.

[0042] To ensure the efficiency of the disassembly device 2 during the disassembly process, after disassembling one optocoupler component 1, the shearing plate 22 needs to move in the opposite direction to the direction of cutting the optocoupler component 1 to reset. Therefore, in this embodiment, an elastic element (not shown) can be provided to push the shearing plate 22 and the positioning block 21 to reset. As one implementation, the disassembly device 2 may also include an elastic element, which is sleeved on the positioning post, and its two ends abut against the upper mounting plate 23 and the positioning block 21, respectively. When the shearing plate 22 and the positioning block 21 slide along the shearing direction, the elastic element is compressed. After the disassembly process of one optocoupler component 1 is completed, the elastic element, due to the restoring force, pushes the upper mounting plate 23 and the positioning block 21 away from each other, so that the shearing plate 22 and the positioning block 21 are reset. In some other embodiments, the elastic element may also be provided in the guide hole 216. For example, the diameter of the elastic element may be smaller than the diameter of the guide hole 216. The elastic element passes through the guide hole 216, and its two ends abut against the positioning block 21 and the positioning post, respectively. Specifically, when the shearing plate 22 and the positioning block 21 slide along the shearing direction, the elastic element is compressed. After the disassembly process of an optical coupling component 1 is completed, the elastic element, due to the restoring force, pushes the upper mounting plate 23 and the positioning block 21 away from each other, so that the shearing plate 22 and the positioning block 21 are reset.

[0043] The disassembly device 2 proposed in this application has the following operating principle:

[0044] The disassembly device 2 proposed in this application provides shearing force to the optocoupler 1 to be disassembled through the relative movement between the shearing plate 22 and the positioning block 21, so that the substrate 10 and the transmitter 20 are separated along the welding plane 30 located on the optocoupler 1. Simultaneously, by providing guide holes 216 and guide posts 231, during the relative movement between the shearing plate 22 and the slider, the guide posts slide along the guide holes 216 to ensure that the shearing plate 22 can slide along the positioning block 21 with high precision and without deviation. The disassembly device 2 provided in this application can disassemble optocouplers 1 of specific shapes through the relative movement between the shearing plate 22 and the positioning block 21. During the disassembly process, the substrate 10 and other transmitters 20 on the optocoupler 1 that do not need to be disassembled are not damaged, allowing materials to be reused and avoiding waste.

[0045] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
