Description

Technical Field

[0001] This invention belongs to the technical field of optical communication module clamping equipment, and specifically relates to a multi-type, multi-product loading carrier for optical communication modules. Background Technology

[0002] In the production, processing, and transportation of optical communication modules, loading carriers are core auxiliary tooling that ensures the stability of module production and improves operational standardization. Currently, the overall dimensions of mainstream optical communication module models with different specifications such as 1.25G, 10G, 25G, and 100G vary significantly. Traditional loading carriers are mostly custom-designed structures for a single model, with fixed structural dimensions that cannot be adaptively adjusted. Different models of optical communication modules cannot share the same set of carriers.

[0003] For optical communication module products of different specifications, manufacturers need to create separate molds and customize dedicated carriers for each model. For multi-model mass production lines, multiple sets of carriers of different specifications need to be stocked, which not only significantly increases the costs of carrier mold creation, manufacturing, procurement, and warehousing management, resulting in serious resource waste and economic losses, but also increases the difficulty of on-site management due to the classification and management of multiple types of carriers, making it easy for carriers to be mixed or misused, affecting production efficiency. At the same time, traditional dedicated carriers have a simple structure and simple clamping and positioning structure, which can only achieve simple placement and support, and have poor limiting and fixing effect on optical communication module units. They cannot effectively constrain the module substrate and individual modules in three-dimensional space, and are prone to module displacement and loosening during transportation and processing, resulting in poor stability.

[0004] Therefore, in order to solve the technical drawbacks of existing optical communication module carriers, such as poor versatility, low adaptability, high production costs, and insufficient fixation stability, it is urgent to design a universal loading carrier that can be adapted to multiple types, has adjustable size, and is fixed stably for multiple products. This would enable the use of optical communication modules across all models, effectively reduce production and supporting costs, and improve the overall efficiency and stability of optical communication module production and transportation operations. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a multi-type, multi-product loading carrier for optical communication modules, in order to solve the problem that the current optical communication module carriers have low adaptability and cannot meet the requirements for clamping and loading optical communication modules of different sizes.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A multi-type, multi-product loading carrier for optical communication modules includes a carrier body for mounting optical communication module units and a first movable block and a second movable block movably mounted on its surface. The surface of the carrier body has an operation window extending through its thickness, and the surface of the carrier body also has a placement groove surrounding the operation window. The first movable block and the second movable block are slidably disposed on one side surface of the carrier body and pass through the operation window. Limiting members are provided between the first movable block, the second movable block and the carrier body. The first movable block and the second movable block are parallel to each other. A first protrusion located inside the operation window is vertically fixed on one side surface of each of the first movable blocks. A second protrusion passing through the operation window is vertically fixed on one side surface of each of the second movable blocks. The surface of the second protrusion is flush with the adjacent surface of the carrier body. A positioning groove is formed on the surface of the second protrusion, and the surfaces of the positioning groove and the first protrusion are flush with the surface of the placement groove.

[0007] Furthermore, the first and second movable blocks are provided in multiple parts and arranged parallel to each other, and the first and second movable blocks are staggered in the same direction; a first limiting block is fixed to the surface of the carrier body near the placement slot, and there is a gap between the first limiting block and the surface of the placement slot; a second limiting block is fixed vertically to the surface of each second boss, and the vertical cross section of the second limiting block is "T" shaped; each second movable block has two positioning slots, and the two positioning slots are symmetrically arranged about the axis of the second limiting block; there is also a gap between the two side wings of the second limiting block and the surface of the second boss, and the second limiting block and the first limiting block are parallel to each other, and the optical communication module unit is clamped and fixed together through the gap.

[0008] Furthermore, each of the first movable blocks has multiple third movable blocks that move along its length direction slidably connected to its outer surface. Each of the third movable blocks has four positioning blocks vertically fixed to its surface, and the four positioning blocks are arranged symmetrically about the axis of the length direction of the first boss, with the free ends of each positioning block passing through the optical communication module unit and cooperating with the first boss to restrict and fix the optical communication module unit. Each of the third movable blocks has a limit rod threadedly connected to its surface away from the carrier body, and one end of the limit rod passes through the third movable block and abuts against the surface of the first movable block.

[0009] Furthermore, each of the third movable blocks is detachably connected to a clamping plate assembly corresponding to the optical communication module unit. The clamping plate assembly is located on the back of the first movable block and includes a clamping plate and multiple locking blocks and fixing posts vertically arranged on one side surface of the clamping plate. One end of each locking block is elastically hinged to the clamping plate, and the other end passes through the optical communication module unit and is locked to its surface. One end of each fixing post is fixedly connected to the surface of the clamping plate, and the other end abuts against the surface of the optical communication module unit. Each surface of the first movable block is provided with a through hole for the corresponding locking block to pass through.

[0010] Furthermore, each of the third movable blocks has two guide posts vertically fixedly connected to its surface away from the first movable block. The surface of the clamping plate is provided with guide blocks that cooperate with each guide post, and the surfaces of each guide block and the third movable block are inherently magnetic materials that attract each other.

[0011] Furthermore, the limiting component includes two elongated limiting holes and multiple fixing bolts on the surface of the vehicle body. The two limiting holes are located on both sides of the operating window, and the length direction of the two limiting holes is perpendicular to the movement direction of each first movable block and second movable block. Each end of the length direction of each first movable block and second movable block is provided with threaded holes corresponding to the adjacent limiting holes, and each fixing bolt is engaged with the threaded holes.

[0012] Furthermore, the vehicle body, the first movable block, the second movable block, the third movable block, the first boss, the second boss, the first limiting block, and the second limiting block are all made of stainless steel.

[0013] The beneficial effects of this invention are as follows: 1. This invention is adaptable to optical communication module units of different sizes, with strong versatility and flexibility. It can simultaneously load multiple module units with a large loading capacity. Relying on movable blocks, limiting blocks, positioning structures, and gap fits, it achieves multi-level clamping and positioning, which can limit the three-dimensional displacement of the module and greatly improve the stability during transportation. The detachable clamping plate assembly further strengthens the overall structure. Relying on the locking blocks and fixing columns to form fulcrums, it can not only ensure the independence of individual module disassembly and avoid the displacement and loosening of adjacent modules, but also simplify the disassembly operation and improve the efficiency of picking up parts. At the same time, the guide columns and magnetic structure complete the quick pre-positioning and fixing of the clamping plate. With the help of bolt-type limiting parts, the overall operation is simple and the manufacturing cost is low. The main components are made of stainless steel, and the clamping plate is made of transparent plastic, which takes into account both structural strength and service life.

Detailed Implementation

[0016] like Figures 1-9 As shown, A multi-type, multi-product loading carrier for optical communication modules includes a carrier body 2 for mounting optical communication module units 1, and a first movable block 3 and a second movable block 4 movably mounted on its surface. The carrier body 2 has a rectangular operating window extending through its thickness on its surface. A placement groove 5 is also formed around the operating window on the surface of the carrier body 2, recessed into the surface of the carrier body 2, with the height of the recess being the same as the thickness of the optical communication module unit 1. The first movable block 3 and the second movable block 4 are both slidably disposed on one side of the carrier body 2 and pass through the operating window. 3. Limiting components are provided between the second movable block 4 and the carrier body 2, which are used to limit the position between the first movable block 3, the second movable block 4 and the carrier body 2. The first movable block 3 and the second movable block 4 are parallel to each other. A first protrusion 6 is integrally formed on one side surface of the first movable block 3 and is vertically fixed in the operation window. A second protrusion 7 is integrally formed on one side surface of the second movable block 4 and is vertically fixed and passes through the operation window. The surface of the second protrusion 7 is flush with the adjacent surface of the carrier body 2. A positioning groove 8 is provided on the surface of the second protrusion 7. The surfaces of the positioning groove 8 and the first protrusion 6 are flush with the surface of the placement groove 5. The optical communication module unit 1 includes a substrate 101 and ten optical communication modules 102 fixed at intervals on the substrate 101. The substrate 101 is in the shape of an "I" in the horizontal plane. Each optical communication module 102 is symmetrically arranged about the axis of the substrate 101. A connecting block 103 is fixed between each optical communication module 102 and between the optical communication module 102 and the substrate 101. Multiple arrays of small holes are opened at the connection points between each connecting block 103 and the optical communication module 102, and between the connecting block 103 and the substrate 101, so as to facilitate the removal of the optical communication module 102. Multiple first through holes are also opened on the surface of the substrate 101, and each first through hole is arranged in an array along the vertical axis of the substrate 101.

[0017] As shown in the figure, when it is necessary to load the optical communication module unit 1, first move the first movable block 3 and the second movable block 4 to the appropriate positions. Then, move the optical communication module unit 1 onto the placement slot 5 on the surface of the carrier body 2, with one corner of the optical communication module unit 1 corresponding to one corner of the placement slot 5. Next, move the first movable block 3 to a position close to the center of the optical communication module unit 1. At this point, the surface of the first protrusion 6 on the surface of the first movable block 3 abuts against and forms the optical communication module unit 1. The first movable block 3 is then fixed in its current position by the limiting member. Then, continue moving the second movable block 4 to one end of the optical communication module unit 1 until the positioning slot 8 on the surface of the second protrusion 7 abuts against the surface of the optical communication module unit 1. Subsequently, the second movable block 4 is fixed in its current position by the limiting component; the optical communication module unit 1 is clamped and fixed on the surface of the carrier body 2 by the right angle surfaces on both sides of the placement groove 5 and the surface of the positioning groove 8, thereby realizing the loading and fixing of the optical communication module unit 1. Similarly, when multiple optical communication module units 1 need to be clamped, the optical communication module units 1 only need to be placed sequentially at intervals along the length direction of the first movable block 3, and the optical communication module unit 1 is formed by the first protrusion 6. The clamping and fixing of each optical communication module unit 1 is achieved by the joint action of the placement groove 5 and the positioning groove 8, which can effectively realize the loading effect of multiple optical communication module units 1. Of course, the position of the first movable block 3 and the second movable block 4 on the carrier body 2 can be adjusted by moving them, so as to be suitable for clamping and fixing optical communication module units 1 of different sizes, effectively improving the applicability and flexibility of the present invention.

[0018] In this embodiment, multiple first movable blocks 3 and second movable blocks 4 are provided and arranged parallel to each other, and each first movable block 3 and second movable block 4 is staggered along the same direction (only two first movable blocks 3 and two movable blocks 4 are shown in the figure); a first limiting block 9 close to the placement groove 5 is welded and fixed to the surface of the carrier body 2, and there is a gap between the first limiting block 9 and the surface of the placement groove 5, which is the same as the thickness of the optical communication module unit 1; a second limiting block 10 coaxial with it is welded and fixed to the surface of each second protrusion 7, and the vertical cross section of the second limiting block 10 is "T" shaped; two positioning grooves 8 are provided on each second movable block 4, and the two positioning grooves 8 are symmetrically arranged about the axis of the second limiting block 10; there is also a gap between the two side wings of the second limiting block 10 and the surface of the positioning groove 8 of the second protrusion 7, which is the same as the thickness of the optical communication module unit 1, and the second limiting block 10 and the first limiting block 9 are parallel to each other, and together clamp and fix the optical communication module unit 1 through the gap.

[0019] As shown in the figure, when it is necessary to load the optical communication module unit 1, one end of the optical communication module unit 1 is first placed in the gap between the first limiting block 9 and the placement groove 5. Then, the first movable block 3 is moved so that the first protrusion 6 abuts against and supports the optical communication module unit 1. Then, the second movable block 4 is moved towards the optical communication module unit 1 so that the other end of the optical communication module unit 1 is located in the gap between the surface of the second protrusion 7 and the positioning groove 8. At this time, the upper and lower ends of the optical communication module unit 1 are abutted by the first limiting block 9 and the second limiting block 10 respectively, which effectively restricts the longitudinal degree of freedom of the optical communication module unit 1 on the horizontal plane, realizes the further clamping and fixing of the optical communication module unit 1 by the carrier body 2, and effectively improves the stability of the carrier body 2 in the process of transporting the optical communication module unit 1.

[0020] In this embodiment, each of the first movable blocks 3 has multiple third movable blocks 11 that move along its length direction slidably connected to its outer surface. Each of the third movable blocks 11 has four positioning blocks 12 vertically welded to its surface. The four positioning blocks 12 are arranged symmetrically about the axis of the length direction of the first boss 6, with the free end of each positioning block 12 passing through the substrate 101 on the optical communication module unit 1 and cooperating with the first boss 6 to simultaneously restrict and fix the optical communication module unit 1. Each of the third movable blocks 11 has a limit rod 13 threadedly connected to its surface away from the carrier body 2. The limit rod 13 is perpendicular to the surface of the third movable block 11, with one end of the limit rod 13 passing through the third movable block 11 and abutting against the surface of the adjacent first movable block 3, and the other end located outside the third movable block 11.

[0021] As shown in the figure, when mounting the optical communication module unit 1 onto the surface of the carrier body 2, firstly, move the corresponding first movable block 3 and third movable block 11 to a suitable position, with both first movable block 3 and third movable block 11 close to the center of the optical communication module unit 1. Then, place the optical communication module unit 1 at the intersection of the first movable block 3 and third movable block 11, ensuring that the surface of the substrate 101 near the center is simultaneously located between the four positioning blocks 12. Subsequently, move the substrate 101, third movable block 11, and first movable block 3 simultaneously, so that the upper and lower ends of the substrate 101 are respectively located at the first... The inner sides of the limiting block 9 and the second limiting block 10 abut against each other. At this time, the limiting rod 13 can be rotated and moved towards the first movable block 3 until one end of the limiting rod 13 abuts against the surface of the first movable block 3, thereby fixing the third movable block 11. The base plate 101 is fixed to the surface of the carrier body 2 under the combined action of the third movable block 11, the first movable block 3, the first limiting block 9 and the second limiting block 10, which effectively restricts the movement of the base plate 101 in the three-dimensional direction, further improving the connection tightness of the carrier body 2 and making it more stable during transportation.

[0022] In this embodiment, each of the third movable blocks 11 is detachably connected to a clamping plate assembly 14 corresponding to the optical communication module unit 1. The clamping plate assembly 14 is disposed on the back of the first movable block 3, and includes a clamping plate 1401 and multiple locking blocks 1402 and fixing posts 1403 vertically disposed on one side surface of the clamping plate 1401. The number and position of each locking block 1402 correspond one-to-one with the connecting block 103, and the number and position of each fixing post 1403 correspond one-to-one with the optical communication module 102. One end of each locking block 1402 springs against the clamping plate 1401. The two ends of each fixed post 1402 are hinged and pass through the connecting block 103 on the optical communication module unit 1 and are engaged with each other. One end of each fixed post 1403 is fixedly connected to the surface of the clamping plate 1401, and the other end abuts against the surface of the optical communication module 102 near the center. When each locking block 1402 and the connecting block 103 are engaged with each other and the fixed post 1403 abuts against the surface of the optical communication module 102, the surface of the clamping plate 1401 just abuts against the surface of the first movable block 3. Each surface of the first movable block 3 is provided with a through hole for the corresponding locking block 1402 to pass through. The clamping plate 1401, the locking block 1402, and the fixing post are all made of transparent plastic. The surface of the clamping plate 1401 is provided with grooves that correspond one-to-one with the number and position of the locking blocks 1402. One end of each locking block 1402 is located in the groove and is elastically hinged to the locking block 1402 (the specific connection method is common knowledge to those skilled in the art, and will not be elaborated here).

[0023] As shown in the figure, when the optical communication module unit 1 is fixed in the corresponding position of the carrier body 2 under the combined action of the first movable block 3, the second movable block 4, and the third movable block 11, the clamping plate assembly 14 is moved from the back of the carrier body 2 toward the corresponding optical communication module unit 1. During installation, first ensure that the center of the clamping plate 1401 and the base plate 101 are on the same straight line. Then, align each of the locking blocks 1402 on the base plate 101 with the corresponding gap position between each optical communication module 102 and the clamping plate 1401, and move it toward the base plate 101 until each is fixed. The free ends of the posts 1403 abut against the surfaces of the corresponding optical communication modules 102, and the surfaces of the clamping plates 1401 abut against the surfaces of the first movable blocks 3. At this time, each locking block 1402 also engages with the corresponding connecting blocks 103. The clamping plates 1401 secure the substrate 101 to the surface of the carrier body 2. One end of each fixing post 1403 can provide effective support to the corresponding optical communication modules 102. In conjunction with the first movable block 3, the second movable block 4, and the third movable block 11, the effective clamping and fixing of each optical communication module unit 1 by the carrier body 2 is further improved. Furthermore, when it is necessary to remove one of the optical communication modules 102, the operator can pinch one end of the gold fingers of the optical communication module 102 and then rotate it away from the clamp 1401 (in conjunction with...). Figure 9As shown, this disconnects the connection with each connecting block 103. Since one end of each fixing post 1403 abuts against the center of the optical communication module 102, the optical communication module 102 rotates around the end face of the fixing post 1403 as a fulcrum during rotation until it is removed. Since each locking block 1402 engages with the corresponding connecting block 103, when rotating the optical communication module 102, its rotation direction is opposite to the direction of restriction of the connecting block 103 by each locking block 1402. Furthermore, when rotating one of the optical communication modules 102 and disconnecting it from the corresponding connecting block 103, each locking block 1402 also effectively prevents the adjacent optical communication modules 102 from being displaced or unstable under the action of the connecting block 103. This effectively ensures the independence of each optical communication module 102 when it is removed from the substrate 101, and also improves the efficiency of removing each optical communication module 102.

[0024] In this embodiment, each of the third movable blocks 11 has two guide posts 15 vertically fixedly connected to the surface away from the first movable block 3. The two guide posts 15 are symmetrically arranged about the vertical axis of the third movable block 11. The surface of the clamping plate 1401 is provided with guide blocks 16 that cooperate with each guide post 15. The surfaces of each guide block 16 and the third movable block 11 adjacent to each other are inherently magnetic materials that attract each other (such as magnets and other known materials, which are not shown in the figure).

[0025] As shown in the figure, when the clamping plate 1401 is engaged with the substrate 101, the guide block 16 on the clamping plate 1401 can be aligned with the two guide posts 15 to pre-position the clamping plate 1401. Then, the clamping plate 1401 can be moved toward the substrate 101 until each locking block 1402 is engaged with the corresponding connecting block 103 and one end of each fixing post is in contact with the optical communication module 102. At this time, each guide block 16 and the third movable block 11 are attracted to each other by magnetic material, effectively fixing the clamping plate 1401.

[0026] In this embodiment, the limiting component includes two elongated limiting holes 17 and multiple fixing bolts 18 on the surface of the carrier body 2. The two limiting holes 17 are located on both sides of the operating window, and the length direction of the two limiting holes 17 is perpendicular to the movement direction of each first movable block 3 and second movable block 4. Both ends of the length direction of each first movable block 3 and second movable block 4 are provided with threaded holes corresponding to the adjacent limiting holes 17, and each fixing bolt 18 is respectively engaged with the threaded holes.

[0027] As shown in the figure, by rotating the fixing bolt 18, it abuts against the surface of the carrier body 2 around the limiting hole 17, thereby moving or fixing the first movable block 3 and the second movable block 4. The operation is simple and convenient, and the production cost is low.

[0028] In this embodiment, the carrier body 2, the first movable block 3, the second movable block 4, the third movable block 11, the first boss 6, the second boss 7, the first limiting block 9, and the second limiting block 10 are all made of stainless steel, which effectively improves the service life of the present invention.

[0029] The above description of the embodiments is provided to enable those skilled in the art to understand and apply the present invention. It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the embodiments described herein, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the invention should be within the protection scope of the present invention.
