Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical fiber equipment, in particular to an optical component mounting jig and an optical component mounting method. BACKGROUND

[0002] In optical fiber communication, there are many factors affecting the production efficiency of optical modules, the most prominent of which is the assembly of isolators. Isolators are an indispensable component in optical modules, and isolators have magnets. In the production process, isolators need to be placed into metal components manually by using tweezers. The metal components have slight magnetism, so during the placement process, the isolators will be displaced or turned over due to the magnetism of the metal components, resulting in low installation precision and reduced production efficiency in the subsequent adjustment process. SUMMARY

[0003] The present application provides an optical component mounting jig and an optical component mounting method to solve the above problems.

[0004] In a first aspect, the present application provides an optical component mounting jig, the optical component comprising a base and an isolator with magnetism, the base being provided with a mounting hole, and the isolator being assembled in the mounting hole, characterized in that the optical component mounting jig comprises: a mounting seat for fixing the base; and a magnetic member provided on the mounting seat and configured to provide a driving force to the isolator to drive the isolator to enter the mounting hole in a predetermined assembly direction.

[0005] In some embodiments, the mounting hole penetrates through the base and has opposite first and second openings, and an inner wall surrounding the mounting hole is formed with a clamping portion close to the second opening. When the isolator enters the mounting hole from the first opening, the magnetic member is configured to provide a driving force to the isolator to move the isolator to abut against the clamping portion.

[0006] In some embodiments, when the base is fixed to the mounting seat, the magnetic member is located on a side of the base close to the second opening.

[0007] In some embodiments, the optical component mounting jig further comprises a mounting arm, and the magnetic member is provided on the mounting arm. The mounting arm drives the magnetic member to move in the axial direction of the mounting hole to push the isolator by repulsion between magnetic poles with the same polarity.

[0008] In some embodiments, the spacer has first and second magnetic faces with opposite polarities, the magnetic member has first and second magnetic ends with opposite polarities, and the magnetic member is proximate to one end of the spacer and opposite in polarity to one face of the spacer.

[0009] In some embodiments, the optical assembly mounting jig further comprises a mounting arm having a first end and a second end, the first end is disposed on the mounting seat, and the magnetic member is disposed on the second end, the mounting arm is used to be inserted into the mounting hole from the first opening so that the magnetic member is proximate to the spacer.

[0010] In some embodiments, the optical assembly mounting jig further comprises a clamp disposed on the mounting seat and used to be detachably connected with the base.

[0011] In some embodiments, the clamping portion comprises a boss formed on the edge of the second opening.

[0012] In a second aspect, the present application provides an optical assembly mounting method, which is applied to the optical assembly mounting jig as described above, and comprises the following steps: fixing the base on the mounting seat; placing the magnetic member on the mounting seat, and setting the magnetic pole direction along the axis direction of the mounting hole; and placing the spacer adjacent to or in the mounting hole so that the spacer is driven by the magnetic member to move along the axis direction of the mounting hole to the assembly position.

[0013] In some embodiments, the step of placing the spacer adjacent to or in the mounting hole so that the spacer is driven by the magnetic member to move along the axis direction of the mounting hole to the assembly position comprises: adjusting the magnetic pole direction of the spacer to be opposite to the magnetic pole direction of the magnetic member, and placing the spacer adjacent to or in the mounting hole.

[0014] The optical assembly mounting jig provided by the present application fixes the base of the optical assembly on the mounting seat. In the assembly process of the optical assembly, the spacer in the optical assembly is placed into the mounting hole on the base. The optical assembly mounting jig further comprises a magnetic member. Since the spacer itself has magnetism, the magnetic member and the spacer are driven by the interaction force between them to move in the mounting hole and finally reach the assembly position. The optical assembly mounting jig provided by the present application drives the spacer to move by the interaction force between the magnetic member and the spacer. Since the magnetic interaction force between the magnetic member and the spacer is larger than the magnetic interaction force between the spacer and the base, the installation precision of the spacer is not affected by the magnetic interaction force between the spacer and the base. Meanwhile, the installation process of the spacer is more efficient. BRIEF DESCRIPTION OF DRAWINGS

[0024] Embodiment one

[0025] Please refer to Figure 1 In the related art, the optical assembly 10 includes a base 20 and a spacer 30. The base 20 can be made of metal, and has a receiving cavity arranged therein for receiving an accessory such as a lens. The base 20 further has a mounting hole 40 formed therein, and the mounting hole 40 is in communication with the receiving cavity. The mounting hole 40 can have a certain length and be in communication with the receiving cavity. The mounting hole 40 extends through the base 20 and has a first opening 41 and a second opening 42, and the first opening 41 and the second opening 42 are located at opposite ends of the mounting hole 40. The first opening 41 can be located in the receiving cavity, and the second opening 42 can be located on the surface of the base 20.

[0026] When the spacer 30 is received in the mounting hole 40, the spacer 30 can not be fixed in the mounting hole 40. Therefore, in the optical assembly 10 described in the embodiment, a clamping portion 50 is formed on the inner wall of the mounting hole 40, and the clamping portion 50 is used to fix the spacer 30 in the mounting hole 40. The clamping portion 50 is located at the edge of the second opening 42 and abuts against the spacer 30 received in the mounting hole 40, so that the spacer 30 can be fixed in the mounting hole 40.

[0027] It can be understood that the clamping portion 50 can be a boss formed at the edge of the second opening 42, and the boss extends from the side wall of the mounting hole 40 towards the central axis of the mounting hole 40. The diameter of the mounting hole 40 at the position where the boss is formed is smaller than the diameter of the mounting hole 40 at other positions. Therefore, when the spacer 30 with a diameter matching the diameter of the mounting hole 40 at the position where the boss is not formed is placed in the mounting hole 40 at the first opening 41 of the mounting hole 40, the spacer 30 moves from the first opening 41 towards the second opening 42 until it stops moving after abutting against the boss. The clamping portion 50 can also be another structure for limiting the position, such as a protrusion on the inner wall of the mounting hole 40, and the like, which is not limited herein.

[0028] Since the isolation piece 30 needs to have a function such as electromagnetic isolation, the isolation piece 30 itself has a certain magnetic property. During the installation of the isolation piece 30 and the base body 20, the magnetic property of the isolation piece 30 can interact with the metal part on the base body 20, causing the installation position to deviate. Based on this, the optical assembly installation jig 100 is proposed to improve the above problem.

[0029] Please refer to Figure 2 , the optical assembly installation jig 100 proposed in the present application includes a mounting seat 90 and a magnetic piece 80.

[0030] The mounting seat 90 is used to fix the base body 20, so as to facilitate the assembly of the isolation piece 30 in the mounting hole 40. For example, in the embodiment, please continue to refer to Figure 2 , the mounting seat 90 is also provided with a clamp 70, and the clamp 70 and the base body 20 can be connected in a detachable manner. Specifically, the clamp 70 can include oppositely arranged first and second clamping heads 71 and 72, and a clamping space is formed between the first and second clamping heads 71 and 72. It can be understood that the first and second clamping heads 71 and 72 can move relative to each other to expand or shrink the clamping space. When the clamping space shrinks, the base body 20 can be clamped to fix the base body 20. The first and second clamping heads 71 and 72 can be connected by a spring, or can be connected by other means such as an extension rod, and the specific connection mode is not limited.

[0031] In some other embodiments, since different base bodies 20 have different shapes, in some embodiments, the clamp 70 can also be a structure that is adapted to the shape of the base body 20. For example, the base body 20 can be a cuboid-shaped base body 20, and the clamp 70 is provided with a fixing groove, the shape of the fixing groove is adapted to the cuboid-shaped base body 20, and by placing the base body 20 in the fixing groove, the function of fixing the base body 20 can also be achieved.

[0032] As Figure 3 indicated, the magnetic piece 80 is used to drive the isolation piece 30 to enter the mounting hole 40 in a predetermined assembly direction. As an embodiment, when the base body 20 is connected with the mounting seat 90, the magnetic piece 80 drives the isolation piece 30 by using the attractive force between the magnetic poles with different polarities.

[0033] Specifically, the magnetic member 80 includes a first side 81 and a second side 82, the first side 81 and the second side 82 are opposite in polarity. The isolation member 30 can also include a first face 31 and a second face 32 opposite in polarity. It can be understood that the isolation member 30 in the embodiment can be substantially cylindrical, and the cylindrical isolation member 30 is convenient to cooperate with the mounting hole 40 to ensure the installation accuracy of the isolation member 30 in the mounting hole 40. The first face 31 and the second face 32 can be two end faces of the cylindrical isolation member 30, respectively. In assembly, the magnetic pole direction of the isolation member 30 is arranged along the axial direction of the mounting hole 40, that is, when the isolation member 30 is located in the mounting hole 40, the second face 32 is arranged towards the side of the base 20 provided with the opening.

[0034] As shown in the example, Figure 3 the polarity of the first side 81 can be N pole, and the polarity of the second side 82 can be S pole. The polarity of the first face 31 of the isolation member 30 can be N pole, and the polarity of the second face 32 can be S pole. In the embodiment, the magnetic member 80 is arranged on the side of the mounting hole 40 close to the second opening 42, and the first side 81 of the magnetic member 80 is close to the first opening. In assembly, the second face 32 of the isolation member 30 is first inserted into the mounting hole 40 from the first opening 41, at this time, the second face 32 is opposite to the first side 81 of the magnetic member 80. It can be understood that since the polarity of the second face 32 is S pole and the polarity of the first side 81 is N pole, the S pole and the N pole attract each other, the magnetic member 80 slides from the first opening 41 towards the second opening 42 under the action of the magnetic force F, until it is located in the mounting position and abuts against the clamping portion 50.

[0035] In some other embodiments, the isolation member 30 can also be moved by repulsion between the same magnetic poles. Please refer to Figure 4 , the optical component mounting jig 100 can also include a mounting arm 110, the magnetic member is arranged on the mounting arm, and the mounting arm drives the magnetic member to move in the axial direction of the mounting hole to push the isolation member by repulsion between the same polarity magnetic poles.

[0036] Specifically, as an embodiment, the mounting arm 110 can include a connecting end 111 and a mounting end 112, the connecting end 111 is in sliding connection with the mounting seat 90, and the sliding direction is parallel to the axial direction of the mounting hole 40 when the base 30 is fixed on the mounting seat 90. The mounting end 112 is used to arrange the magnetic member 80. In the embodiment, the connecting end 111 is connected with the mounting end 112. As shown in the example, Figure 4 the mounting end 112 can be connected to one side of the connecting end 111 and extend towards the direction where the clamp 70 is located. The magnetic member 80 is arranged on the side of the mounting end 112 towards the clamp 70, and when the base 20 is fixed on the mounting seat 90, the magnetic member is located on the axis of the mounting hole 40.

[0037] It can be understood that in the embodiment, the second side 82 of the magnetic member 80 can be S-pole. When the base 20 is assembled on the jig 70, the position of the magnetic member 80 corresponds to the first opening 41 of the mounting hole 40. During the assembly, the magnetic member 80 can be moved away from the first opening 41 through the sliding between the connecting end and the mounting seat, at this time the isolation member 30 can be put into the mounting hole 40 from the first opening 41, and the side of the isolation member 30 facing the second side 82 of the magnetic member 80 is also S-pole. Then, the magnetic member 80 is moved towards the first opening 41 by sliding the mounting arm. Due to the principle of repulsion between the same magnetic poles, the isolation member 30 is pushed by the magnetic member 80 and slides from the first opening 41 towards the second opening 42 until it is located in the mounting position and abuts against the clamping part 50.

[0038] The optical assembly mounting jig 100 provided in the embodiment fixes the base 20 of the optical assembly 10 through the mounting seat 90. During the assembly of the optical assembly 10, the isolation member 30 in the optical assembly 10 is put into the mounting hole 40 on the base 20, and the optical assembly mounting jig 100 further comprises the magnetic member 80. Since the isolation member 30 itself has magnetism, the acting force between the magnetic member 80 and the isolation member 30 drives the isolation member 30 to move in the mounting hole 40 and finally be located in the mounting position. The optical assembly mounting jig 100 provided in the application drives the isolation member 30 to move through the acting force between the magnetic member 80 and the isolation member 30. Since the magnetic acting force between the magnetic member 80 and the isolation member 30 is larger than the magnetic acting force between the isolation member 30 and the base 20, the installation precision of the isolation member 30 is not affected by the magnetic acting force between the isolation member 30 and the base 20, and the installation process of the isolation member 30 is relatively simple.

[0039] Embodiment two

[0040] Please refer to Figure 5 The application further provides an optical assembly mounting method, which is applicable to the optical assembly mounting jig provided in embodiment one and comprises steps S101-S103.

[0041] S101: fixing the base on the mounting seat.

[0042] Please refer to Figure 1The base 20 can be made of metal material, and has a receiving cavity for receiving an accessory such as a lens. The base 20 further has a mounting hole 40 which communicates with the receiving cavity. The mounting hole 40 can have a certain length and communicate with the receiving cavity. The mounting hole 40 can pass through the base 20 and have a first opening 41 and a second opening 42 which are located at opposite ends of the mounting hole 40. The first opening 41 can be located in the receiving cavity, and the second opening 42 can be located on the surface of the base 20. The inner wall of the mounting hole 40 forms a clamping portion 50 which is used to fix the spacer 30 in the mounting hole 40. The clamping portion 50 is located at the edge of the second opening 42 and abuts against the spacer 30 in the mounting hole 40, so that the spacer 30 can be fixed in the mounting hole 40.

[0043] The clamping portion 50 can be a boss formed at the edge of the second opening 42, and the boss extends from the side wall of the mounting hole 40 towards the central axis of the mounting hole 40. The diameter of the mounting hole 40 at the boss is smaller than that of the mounting hole 40 at other positions. Therefore, when the spacer 30 which is matched with the diameter of the mounting hole 40 at other positions is placed in the mounting hole 40 at the first opening 41 of the mounting hole 40, the spacer 30 moves from the first opening 41 towards the second opening 42 until it stops moving after abutting against the boss.

[0044] S102: Place the magnetic member in the mounting seat, and set the magnetic pole direction along the axis direction of the mounting hole.

[0045] The magnetic member 80 can be a part of the optical component mounting jig 100. The optical component mounting jig 100 further includes a mounting seat 90 which is used to fix the base 20 and facilitate the assembly of the spacer 30 in the mounting hole 40. The magnetic member 80 is used to drive the spacer 30 to enter the mounting hole 40 in a predetermined assembly direction. When the base 20 is connected with the mounting seat, the magnetic member 80 drives the spacer 30 by using the attractive force between the magnetic poles with different polarities.

[0046] The magnetic member 80 comprises a first side 81 and a second side 82, the polarities of the first side 81 and the second side 82 are opposite. The isolation member 30 can also comprise a first face 31 and a second face 32, the polarities of the first face 31 and the second face 32 are also opposite. It can be understood that the isolation member 30 in the embodiment can be substantially cylindrical, and the cylindrical isolation member 30 is convenient to cooperate with the mounting hole 40. The first face 31 and the second face 32 can be two end faces of the cylindrical isolation member 30 respectively. When the isolation member 30 is located in the mounting hole 40, the second face 32 is arranged towards the side of the base 20 provided with the opening. Since the force between the magnetic member 80 and the isolation member 30 is a single direction force, in order to ensure that the force of the magnetic member 80 can push the isolation member 30 to move to the greatest extent, the direction of the force of the magnetic member 80 and the isolation member 30 coincides with the movement direction of the isolation member 30, that is, the magnetic member 80 is arranged on the axis of the mounting hole 40.

[0047] S103: Place the isolation member adjacent to the mounting hole or in the mounting hole, so that the isolation member is driven by the magnetic member to move along the axis direction of the mounting hole to the assembly position.

[0048] The polarity of the first side 81 can be N-pole, and the polarity of the second side 82 can be S-pole. The polarity of the first face 31 of the isolation member 30 is N-pole, and the polarity of the second face 82 is S-pole. The magnetic member 80 is arranged on the side of the mounting hole 40 close to the second opening 42, and the first side 81 of the magnetic member 80 is close to the first opening. When assembled, the second face 32 of the isolation member 30 first extends into the mounting hole 40 from the first opening 41, and at this time the second face 32 is opposite to the first side 81 of the magnetic member 80. It can be understood that since the polarity of the second face 32 is S-pole and the polarity of the first side 81 is N-pole, the S-pole and the N-pole attract each other, and the magnetic member 80 slides from the first opening 41 towards the second opening 42 under the action of the magnetic force, until it is located in the assembly position and abuts against the clamping portion 50.

[0049] Before the isolation member 30 is placed in the mounting hole 40, there can be a problem that the magnetic pole direction of the isolation member 30 cannot be distinguished. Therefore, the isolation member is placed adjacent to the mounting hole or in the mounting hole, so that the isolation member is driven by the magnetic member to move along the axis direction of the mounting hole to the assembly position, comprising the step S201:

[0050] S201: Adjust the magnetic pole direction of the isolation member to be opposite to the magnetic pole direction of the magnetic member, and place the isolation member adjacent to the mounting hole or in the mounting hole.

[0051] It can be understood that the process of placing the spacer 30 can be operated by the installer, such as using a clamp 70 such as tweezers to clamp. In order to ensure that the second surface 32 of the spacer 30 can be aligned with the first side 81 of the magnetic pole when the spacer 30 is placed in the mounting hole 40, the spacer 30 can be stopped near the first opening 41 before being placed in the mounting hole 40. Under the action of the magnetic member 80, the spacer 30 will rotate so that the second surface 32 of the spacer 30 faces the first side 81 of the magnetic pole.

[0052] The optical assembly mounting method provided by the embodiment first provides the base body 20 and the spacer 30 with magnetism, the base body 20 has the mounting hole 40, then provides the magnetic member 80, the magnetic member 80 is arranged on the axis of the mounting hole 40, and finally the spacer 30 is assembled in the mounting hole 40, and the spacer 30 is driven by the magnetic member 80 to move along the mounting hole 40 to the assembly position. The optical assembly mounting method provided by the application drives the spacer 30 to move through the magnetic force between the magnetic member 80 and the spacer 30. Since the magnetic force between the magnetic member 80 and the spacer 30 is larger than the magnetic force between the spacer 30 and the base body 20, the installation precision of the spacer 30 is not affected by the magnetic force between the spacer 30 and the base body 20, and the installation process of the spacer 30 is relatively simple.

[0053] The above embodiments are only used to illustrate the technical solutions of the application, rather than limit them; although the application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the application, and should be included in the protection scope of the application.
