Description

Technical Field

[0001] This invention relates to the field of optical communication technology, and in particular to a multi-fiber ferrule and lens bonding and curing clamping device and its usage method. Background Technology

[0002] Optical modules used in optical communication are evolving towards higher speeds, miniaturization, higher density, and lower power consumption. Especially in miniaturized optical modules, higher demands are placed on the structural performance of optical devices and modules. Ensuring the stability of lens and ferrule connections, as well as improving the environmental adaptability and mechanical reliability of optical devices, are important technical performance indicators, provided that the optical devices function normally within the optical module.

[0003] Based on the current structural and technological characteristics, the connection between the lens and the multi-fiber termination (MT) ferrule is mainly achieved by adhesive bonding. During the bonding process, there will be adhesive displacement between the optical device lens and the MT ferrule, which will result in poor stability of the optical port during subsequent operation. This will lead to the risk of power drop, reduced responsiveness and sensitivity of the optical module during use. In particular, the bonding of dual miniMT ferrules with parallel dual lenses requires two curing processes: one light curing (room temperature curing) and one structural adhesive curing. The structural adhesive curing environment requires a stable temperature of 110℃ for 1 hour to complete the curing process in order to ensure its mechanical reliability and stability.

[0004] During the curing process of structural adhesive, as the adhesive gradually becomes more viscous, the components require precise positioning and proper fixation. Otherwise, the components may shift due to changes in adhesive viscosity. To prevent this, clamps or fixing devices must be used to secure the components, ensuring that they remain accurately positioned during adhesive curing. At the same time, appropriate pressure must be maintained to ensure good adhesion between the components and the adhesive, preventing displacement caused by changes in adhesive viscosity and thus guaranteeing the quality and stability of the bond.

[0005] In existing technologies, such as Figure 1 As shown, most of them adopt a double-row pin spring fixing structure, including a first pin spring assembly 1' and a second pin spring assembly 2'. The first pin spring assembly 1' elastically abuts against one of the MT inserts 3', and the second pin spring assembly 2' elastically abuts against the other MT insert 3'. The first pin spring assembly 1' and the second pin spring assembly 2' need to fix the MT inserts 3' in sequence. Moreover, the first pin spring assembly 1' and the second pin spring assembly 2' are relatively large in size. In actual operation, there are problems such as cumbersome operation, visual obstruction, light curing obstruction, and low operation efficiency.

[0006] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

During the sliding process of the adapter base 22, the elastic structure between the adapter base 22 and the positioning base 1 is compressed.

[0052] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0053] Example 1:

[0054] Embodiment 1 of the present invention provides a multi-fiber ferrule and lens bonding and curing clamping device, such as Figure 2 As shown, it includes: a positioning base 1 and a pressure plate assembly 2; the pressure plate assembly 2 includes a pressure plate body 20 and a transition base 22, the pressure plate body 20 being able to rotate relative to the transition base 22 about a fixed axis; the transition base 22 is slidably connected to the positioning base 1, and the transition base 22 elastically abuts against the positioning base 1. A circuit board 3 is placed on the positioning base 1, and a first lens 31 and a second lens 32 are arranged side-by-side on the circuit board 3. The first lens 31 and the second lens 32 are fixedly connected to the circuit board 3. A first MT ferrule 33 is inserted into the coupling end face of the first lens 31, and a second MT ferrule 34 is inserted into the coupling end face of the second lens 32; wherein the first lens 31 and the second lens 32 are bonded to the circuit board 3 by adhesive bonding. The pressure plate body 20 includes a first abutting arm 200 and a second abutting arm 201. The first abutting arm 200 is used to abut against the tail of the first MT insert 33, and the second abutting arm 201 is used to abut against the tail of the second MT insert 34.

[0055] In this embodiment of the invention, when fixing the first MT insert 33 and the second MT insert 34, the pressure plate body 20 is flipped downwards and pressed down until it is horizontal. The pressure plate body 20 is then released and locked. The first abutment arm 200 abuts against the tail of the first MT insert 33, and the second abutment arm 201 abuts against the tail of the second MT insert 34. This allows for the simultaneous fixing of the first MT insert 33 and the second MT insert 34, simplifying the operation and effectively improving work efficiency. Compared with existing structures, the clamping device provided by this invention is smaller in size, has fewer visual obstacles during operation, and effectively reduces light curing obstruction.

[0056] In the aforementioned scheme, the pressure plate body 20 rotates around a fixed axis, as shown below. Figure 3 As shown, specifically, a rotating shaft connector 202 is provided on the lower surface of the pressure plate body 20. The rotating shaft connector 202 is fixedly connected to the pressure plate body 20, and the adapter base 22 is rotatably connected to the rotating shaft connector 202, thereby enabling the pressure plate body 20 to rotate around the rotation center. The rotatable connection can be a hinge connection. Specifically, the rotating shaft connector 202 is provided with a rotating shaft (not shown in the figure), and the adapter base 22 is provided with a rotating hole (not shown in the figure), forming a rotatable connection between the rotating shaft and the rotating hole.

[0057] As mentioned in the aforementioned scheme, the pressure plate assembly 2 is slidably connected to the positioning base 1, such as... Figure 3 and Figure 4 As shown, specifically, a first mounting plate 220 is machined and provided on one side of the adapter base 22, and a slider 23 is provided on the side of the first mounting plate 220; wherein, the first mounting plate 220 can be formed by bending the bottom plane of the adapter base 22 upward, or the first mounting plate 220 can be fixedly connected to the bottom plane of the adapter base 22 by bolts or adhesive. Figure 3 and Figure 5 As shown, the positioning base 1 is provided with a first mounting position 10, and the first mounting position 10 is provided with a coupling rail 100; the upper and lower sides of the coupling rail 100 are provided with a ball array 101 and a ball mounting plate 102, the ball array 101 is limited by the ball mounting plate 102 and is rotatably connected to the ball mounting plate 102; the upper and lower surfaces of the coupling rail 100 are respectively provided with a first arc-shaped slide rail 103, and the upper and lower surfaces of the slider 23 are respectively provided with a second arc-shaped slide rail 230. The ball array 101 and the ball mounting plate 102 are located between the first arc-shaped slide rail 103 and the second arc-shaped slide rail 230. The ball array 101 is used to enable the coupling rail 100 and the slider 23 to move relatively smoothly within a short distance.

[0058] In the aforementioned scheme, the pressure plate assembly 2 and the positioning base 1 are elastically abutted together, such as... Figure 4 and Figure 5 As shown, specifically, the adapter base 22 is provided with an abutment baffle 221, which is located on the opposite side of the first mounting plate 220. The abutment baffle 221 can be integrally formed with the body of the adapter base 22, or connected to the bottom surface of the adapter base 22 by welding. The positioning base 1 is provided with a second mounting position 11, and a first through hole 110 is provided on the side wall of the second mounting position 11. The first through hole 110 is opposite to the abutment baffle 221, and a spring 111 is provided inside the first through hole 110. The outer end of the first through hole 110 is closed by a set screw 112. (See reference...) Figure 6 As shown, one end of the spring 111 abuts against the set screw 112, and the other end abuts against the abutment baffle 221. When pressure is applied to the pressure plate body 20 in the direction of the spring 111, the spring 111 is compressed, and the pressure plate body 20 is flipped downwards to abut against the positioning base 1. When the pressure plate body 20 is released, the spring 111 applies a pushing force to the abutment baffle 221, so that the first abutment arm 200 abuts against the tail of the first MT insert 33, and the second abutment arm 201 abuts against the tail of the second MT insert 34.

[0059] In a preferred embodiment, the first abutment arm 200 is elastic. For example... Figure 7 As shown, an elastic pressure plate 21 is provided at one end of the pressure plate body 20. The elastic pressure plate 21 extends inward to form the first abutment arm 200. The end of the elastic pressure plate 21 extends inward to form the suspended first abutment arm 200.

[0060] A spring sheet 210 is machined and provided at the location of the first abutment arm 200. One end of the spring sheet 210 is fixedly connected to the body of the elastic pressure plate 21. A gap 212 with a preset distance is provided between the spring sheet 210 and the body of the elastic pressure plate 21. The end of the spring sheet 210 connected to the elastic pressure plate 21 is a rectangular wave structure 2101, which is used to make the spring sheet 210 play a buffering role.

[0061] The pressure exerted by the first abutment arm 200 on the first MT ferrule 33 and the pressure exerted by the second abutment arm 201 on the second MT ferrule 34 depend on the design structure of the spring 111 and the spring piece 210. Experimental verification shows that the first MT ferrule 33 and the second MT ferrule 34 will not be damaged.

[0062] To ensure the flatness of the bottom surfaces of the pressure plate body 20 and the elastic pressure sheet 21, such as Figure 8As shown, the end of the pressure plate body 20 that couples with the elastic pressure plate 21 is provided with a first coupling step 206, and the elastic pressure plate 21 is provided with a second coupling step 211. The first coupling step 206 and the second coupling step 211 are coupled and fixed to each other, thereby ensuring that the bottom surfaces of the pressure plate body 20 and the elastic pressure plate 21 are flat. Alternatively, the elastic plate 210 can be directly formed on the pressure plate body 20 by cutting.

[0063] Specifically, the operating environment temperature of the clamping device is from room temperature to above 100 degrees Celsius. Therefore, the spring sheet 210 needs to be able to perform compression and reset functions within the above temperature range. To meet the aforementioned requirements, the elastic pressure plate 21 is made of metal material, and the metal material used can ensure that the spring sheet 210 resets after compression in a high-temperature environment.

[0064] In this embodiment, the connection between the spring piece 210 and the elastic pressure plate 21 is designed as a rectangular wave structure 2101 because a pre-set gap 212 is provided between the spring piece 210 and the body of the elastic pressure plate 21. This gap 212 compensates for any excess distance between the spring piece 210 and the first MT insert 33, ensuring a tight contact between them. The rectangular wave design at the connection avoids deformation or damage caused by stress concentration at the connection point after the spring piece 210 is pushed, thus extending the service life of the elastic pressure plate 21. Figure 9 As can be seen, the open end of the spring piece 210 abuts against the tail of the first MT insert 33. Therefore, the spring piece 210 fixes the first MT insert 33 using the lever principle, ensuring the clamping force required. Secondly, in order to ensure that the force applied by the spring 111 to the pressure plate body 20 can make the spring piece 210 and the first MT insert 33 fit tightly together, the elastic force of the spring 111 needs to be greater than twice the elastic force of a single spring piece 210, which meets the pressure required for bonding and curing (about 2N).

[0065] When the spring 210 and the first MT insert 33 are in close contact, the open end of the pressure plate body 20 may lift up due to the pressure. In order to ensure the bonding accuracy between the first MT insert 33 and the first lens 31, and between the second MT insert 34 and the second lens 32, the lower surface of the pressure plate body 20 needs to be in close contact with the upper surface of the positioning base 1, so as to avoid displacement between the first MT insert 33 and the first lens 31 and between the second MT insert 34 and the second lens 32 during the adhesive curing process. Based on this, if Figure 9 and Figure 10As shown, the pressure plate assembly 2 further includes a foolproof locking pin 24, which is fixedly connected to the pressure plate body 20. One end of the foolproof locking pin 24 is provided with a positioning pin 240, which is fixedly connected to the foolproof locking pin 24. The foolproof locking pin 24 and the pressure plate body 20 can be fixedly connected by bolts or adhesive. The upper surface of the positioning base 1 is provided with a first receiving groove 12, and a locking limiting block 120 is provided within the first receiving groove 12. The locking limiting block 120 is fixedly connected to the bottom of the first receiving groove 12, and one end face of the locking limiting block 120 is provided with a first circular groove 121, into which the positioning pin 240 is inserted. The locking limiting block 120 and the first receiving groove 12 can be fixedly connected by bolts or adhesive.

[0066] For the pressure plate body 20, since pressure needs to be applied to the pressure plate body 20 to make it move, in order to facilitate manual operation of the pressure plate body 20 to apply pressure, the pressure plate body 20 is provided with a lever handle 205 on both sides, and the lever handle 205 is integrally formed with the pressure plate body 20.

[0067] To avoid photocuring obstruction in the structure of the pressure plate body 20, such as Figure 11 As shown, the pressure plate body 20 is provided with a first skylight 203 and a second skylight 204. The second abutting arm 201 is located on the inner wall of the first skylight 203 and is disposed close to the second skylight 204. The first skylight 203 is used to accommodate the second MT insert 34 and its corresponding second lens 32. The second skylight 204 is used to accommodate the MT plastic seat 35. The MT plastic seat 35 is connected to the first MT insert 33 and the second MT insert 34.

[0068] When placing circuit board 3 on positioning base 1, in order to facilitate the positioning and fixing of circuit board 3, such as... Figure 11 and Figure 12 As shown, a third mounting position 13 is provided on the positioning base 1, and the circuit board 3 is placed in the third mounting position 13; a pressure block 14 is provided at one end of the upper surface of the positioning base 1, the pressure block 14 is fixedly connected to the positioning base 1, and covers the upper surface of the circuit board 3. The pressure block 14 is used to fix the circuit board 3 in the third mounting position 13.

[0069] The pressure block 14 is used to fix the circuit board 3 on the third mounting position 13 after the circuit board 3 is placed on the third mounting position 13. In practical applications, in order to facilitate the placement and removal of the circuit board 3 and to ensure that the third mounting position 13 provides sufficient support for the circuit board 3, the third mounting position 13 is cross-shaped. The cross-shaped third mounting position 13 includes a retrieval slot 130 and a placement slot 131 that are perpendicular to each other. The two ends of the placement slot 131 are provided with a first support platform 132 and a second support platform 133, which are used to support the two ends of the circuit board 3, respectively. The middle of the placement slot 131 is also provided with a support protrusion 134, which is provided on both sides of the placement slot 131 to support the middle of the circuit board 3.

[0070] In practical applications, the connection between the pressure block 14 and the positioning base 1 can also be a rotational connection or a sliding connection. Compared with using bolts to fix the pressure block 14, rotational and sliding connections are more convenient. The specific structural details of rotational and sliding connections can be achieved by existing conventional technologies and will not be shown here.

[0071] In conjunction with the structure provided in the above-described solution, this embodiment of the invention also provides a method for using the multi-fiber ferrule and lens bonding and curing clamping device, applicable to the multi-fiber ferrule and lens bonding and curing clamping device described in the above-described solution, such as... Figure 13 As shown, it includes:

[0072] In step S1, the pressure plate body 20 is pushed toward the end where the fixed axis is located, causing the adapter base 22 to slide backward relative to the positioning base 1 (see...). Figure 14 (The arrow indicates backwards, the same below) until the locking between the pressure plate body 20 and the positioning base 1 is released, continue to press the pressure plate body 20 and flip the pressure plate body 20 upwards.

[0073] Specifically, push the lever 205 on the pressure plate body 20 to move the pressure plate body 20 backward until the positioning pin 240 is completely removed from the locking limit block 120, thus releasing the lock. Then, press and hold the lever 205 and flip the pressure plate body 20 upward to open it.

[0074] In step S2, the circuit board 3 is placed at a preset position on the positioning base 1.

[0075] Specifically, the preset position refers to the third mounting position 13 on the positioning base 1. After the circuit board 3 is placed in the placement groove 131 of the third mounting position 13, the pressure block 14 is used to fix the circuit board 3.

[0076] See Figure 14 As shown, the circuit board 3 is placed on the positioning base 1, and the pressure plate body 20 is open.

[0077] In step S3, the pressure plate body 20 is flipped downwards, and the pressure plate body 20 is pressed to move downwards continuously, causing the adapter base 22 to slide backwards relative to the positioning base 1 until the pressure plate body 20 is in a horizontal state. During the sliding process of the adapter base 22, the elastic structure between the adapter base 22 and the positioning base 1 is compressed.

[0078] Among them, the elastic structure refers to the aforementioned Figure 4 Spring 111 in the middle. During the sliding process of the adapter base 22, it abuts against the baffle 221 to compress spring 111.

[0079] In step S4, the pressure plate body 20 is released, and the elastic structure recovers its deformation, causing the pressure plate body 20 to move forward until the pressure plate body 20 locks with the positioning base 1, so that the first abutting arm 200 abuts with the tail of the first MT insert 33, and the second abutting arm 201 abuts with the tail of the second MT insert 34.

[0080] Specifically, during the process of flipping the pressure plate body 20 downward, the positioning pin 240 is blocked by the locking limit block 120. At this time, press the lever 205 on the pressure plate body 20 and push the pressure plate body 20 backward until the positioning pin 240 is aligned with the first circular groove 121. Release the lever 205 to allow the positioning pin 240 to be inserted into the first circular groove 121, thus completing the locking of the pressure plate body 20.

[0081] After the first MT insert 33 and the second MT insert 34 are brought into contact, the stability between the MT insert and the corresponding lens can be ensured during the bonding process, avoiding displacement caused by changes in the adhesive viscosity, thus ensuring the quality and stability of the bonding.

[0082] Among them, see Figure 14 As shown, the bottom of the pressure plate body 20 is provided with a clearance groove 207, which is used to avoid electronic components on the circuit board 3.

[0083] The multi-fiber ferrule and lens bonding and curing clamping device provided in this embodiment of the invention, compared with the prior art, simplifies the structural design and fully utilizes the elastic reset function of spring 111 and elastic pressure plate 21, reducing operational complexity, making the device easier to process, and increasing production efficiency. It is applicable to different application scenarios, such as bonding, clamping, and curing of the same type of optical modules at different speeds, improving the versatility of the structure. Furthermore, its simple structure and low manufacturing cost make it worthy of widespread application and further meet the needs of selecting a clamping method for MT ferrules under general operating conditions.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
