Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, specifically to a clamping device for optical module processing. Background Technology

[0002] As a key component in optical communication systems, optical modules have seen explosive growth in market demand. In particular, SFP series optical modules, due to their small size, hot-swappable features and standardized interfaces, have become one of the most widely used optical transceivers in network equipment. In the manufacturing process of optical modules, precision control, especially the tolerance management of external dimensions, is crucial. It directly affects whether the product can meet the MSA standard requirements, and thus affects interoperability and market access.

[0003] In the existing SFP optical module manufacturing process, the assembly of the small cover plate and the base generally presents technical challenges. Traditional processes typically use manual screw tightening to fix the small cover plate to the base. However, since the small cover plate is difficult to fully fit with the base in a free state, the following problems occur during the screw tightening process: when the small cover plate is tightened without pressure, it is easy for elastic deformation to occur after the screw is tightened, causing the overall height of the product to exceed the tolerance range allowed by the MSA standard, resulting in reduced product interchangeability, or even inability to insert into the standard interface. Manual operation relies on worker experience, and the pressure applied by different operators or the same operator at different times is inconsistent, resulting in large fluctuations in the size of batch products and a low yield rate. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a clamping device for optical module processing. This solves the technical problem that in the prior art, the assembly of the small cover plate on the optical module and the base is done manually by tightening screws, which results in low tightening efficiency and a low yield rate in subsequent processing.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, this utility model provides a clamping device for optical module processing, comprising:

[0007] The mounting base has a mounting groove on its surface, and a movable channel is provided at the lower end of the mounting groove;

[0008] A fixing plate is detachably connected to the mounting groove. The fixing plate is provided with multiple limiting ends, and the workpiece to be clamped is provided in the limiting ends.

[0009] The clamping end includes a fastener and a drive component, the drive component being mounted on the fixed base for pushing the fastener to move within the movable channel and clamping the workpiece located at the limiting end.

[0010] In some embodiments, a protrusion is provided in the mounting groove.

[0011] In some embodiments, the fixing plate has at least three strip-shaped holes at equal intervals, wherein the middle strip-shaped hole engages with the protrusion.

[0012] In some embodiments, the limiting end includes a plurality of upper grooves formed on the fixed plate, a side wall limiting block, a plurality of upper limiting blocks, and a plurality of lower limiting blocks, wherein the side wall limiting blocks are disposed on the left side of the surface of the fixed plate, and the plurality of upper limiting blocks are equidistantly arranged on the fixed plate and coaxial with the side wall limiting blocks, and the plurality of lower limiting blocks are disposed on the fixed plate and located between adjacent upper limiting blocks.

[0013] In some embodiments, a gap is maintained between adjacent upper limiting blocks, and a workpiece placement groove is formed between the upper groove and the upper groove body.

[0014] In some embodiments, a gap is maintained between adjacent lower limiting blocks, forming a movable groove for the fastener to move.

[0015] In some embodiments, the fastener includes a horizontal plate and a plurality of pressure plates. The horizontal plate is slidably connected to the movable channel, and the plurality of pressure plates are detachably connected to the horizontal plate and can slide left and right in the movable groove. One end of the horizontal plate facing away from the fixed plate is connected to the driving member.

[0016] In some embodiments, the driving component includes a connecting plate and a pushing cylinder. One end of the connecting plate is connected to the horizontal plate, and the other end is connected to the telescopic section of the pushing cylinder. The pushing cylinder is mounted on the fixed base.

[0017] In some embodiments, the connecting plate is an L-shaped plate.

[0018] Compared with existing technologies, the clamping device for optical module processing provided by this utility model uses the mounting slot and movable channel on the fixed base to uniformly clamp the workpiece by pushing the fastener with the driving component. Multiple limiting ends on the fixed plate can simultaneously position multiple workpieces to be processed, and the clamping ends apply stable pressure to all workpieces uniformly, eliminating product quality fluctuations caused by uneven pressure during manual operation, and significantly improving the consistency of products in mass production. The fixed plate is installed in the mounting slot of the fixed base in a detachable connection manner, facilitating quick replacement of matching fixed plates according to different optical module models, improving the versatility and adaptability of the equipment, while simplifying the process. The maintenance process has been streamlined. The drive unit automatically moves the fastener within the movable channel, achieving one-time overall clamping of the workpiece. Compared with the traditional manual pressing method, the single operation time is shortened and the operation steps are simplified, reducing the skill requirements for operators. The movable channel is located at the lower end of the mounting slot, so that the thrust applied by the drive unit acts vertically on the workpiece through the fastener, avoiding workpiece displacement or deformation caused by lateral force. This ensures the precise and stable position of the workpiece during clamping, providing a reliable prerequisite for the subsequent automatic screw fastening process. The stable clamping of the workpiece within the limit end by the fastener effectively controls the elastic deformation of the material during the screw fastening process. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a clamping device for optical module processing according to an embodiment of the present invention. The clamping device for optical module processing includes:

[0028] The fixed base 1 has a mounting groove 11 on its surface, and a movable channel 111 is provided at the lower end of the mounting groove 11.

[0029] The fixing plate 2 is detachably connected to the mounting groove 11. The fixing plate 2 is provided with multiple limiting ends 22, and the workpiece to be clamped is provided in the limiting ends 22.

[0030] The clamping end 3 includes a fastener 31 and a drive member 32. The drive member 32 is mounted on the fixed base 1 and is used to push the fastener 31 to move within the movable channel 111 and clamp the workpiece located at the limiting end 22.

[0031] In this embodiment, the mounting slot 11 on the fixed base 1 cooperates with the movable channel 111, and the driving component 32 pushes the fastener 31 to uniformly press the workpiece. The multiple limiting ends 22 on the fixed plate 2 can simultaneously position multiple workpieces to be processed. With the clamping end 3, a stable pressure is uniformly applied to all workpieces, eliminating product quality fluctuations caused by uneven pressure during manual operation, and greatly improving the consistency of products in mass production. The fixed plate 2 is installed in the mounting slot 11 of the fixed base 1 in a detachable connection manner, which facilitates quick replacement of matching fixed plates 2 according to different models of optical modules, improves the versatility and adaptability of the equipment, simplifies the maintenance process, and reduces equipment management costs. The drive unit 32 automatically pushes the fastener 31 to move within the movable channel 111, achieving one-time overall clamping of the workpiece. Compared with the traditional manual pressing method, the single operation time is shortened and the operation steps are simplified, reducing the skill requirements for operators. The movable channel 111 is located at the lower end of the mounting groove 11, so that the thrust applied by the drive unit 32 acts vertically on the workpiece through the fastener 31, avoiding workpiece displacement or deformation caused by lateral force, ensuring the precise and stable position of the workpiece during clamping, and providing a reliable prerequisite for the subsequent automatic screw fastening process. The stable clamping of the workpiece within the limiting end 22 by the fastener 31 effectively controls the elastic deformation of the material during the screw fastening process.

[0032] In one embodiment, please refer to Figure 1 - Figure 5 To improve the assembly efficiency of the fixing plate 2, a protrusion 12 is provided in the mounting groove 11, and at least three strip holes 21 are equally spaced on the fixing plate 2, wherein the middle strip hole 21 is engaged with the protrusion 12.

[0033] In this embodiment, the engaging structure between the protrusion 12 and the middle strip hole 21 not only ensures the precise position of the fixing plate 2 in the mounting groove 11, but also effectively prevents the operator from installing the fixing plate 2 in reverse. During the production of the optical module, the protrusion 12 only contacts the middle strip hole 21, which greatly reduces the contact area between the fixing plate 2 and the mounting groove 11 and reduces friction and wear. The opening of the strip hole 21 also facilitates the cleaning of metal shavings and dust generated during the screw tightening process, avoiding the accumulation of impurities in the positioning part that affects the accuracy. Maintenance personnel only need simple tools to complete the disassembly and cleaning of the fixing plate 2.

[0034] In one embodiment, please refer to Figure 5To improve the working efficiency of the fixed plate 2, the limiting end 22 includes several upper grooves 221 formed on the fixed plate 2, as well as side wall limiting blocks 222, several upper limiting blocks 223, and several lower limiting blocks 224. The side wall limiting blocks 222 are located on the left side of the surface of the fixed plate 2, and the several upper limiting blocks 223 are equidistantly arranged on the fixed plate 2 and coaxial with the side wall limiting blocks 222. The several lower limiting blocks 224 are located on the fixed plate 2 and between adjacent upper limiting blocks 223, maintaining a gap between adjacent upper limiting blocks 223 and forming a workpiece placement groove with the upper grooves 221. A gap is maintained between 4, forming a movable groove 225 for the fastener 31 to move. The fastener 31 includes a horizontal plate 311 and several pressure plates 312. The horizontal plate 311 is slidably connected to the movable channel 111, and the several pressure plates 312 are detachably connected to the horizontal plate 311 and can slide left and right in the movable groove 225. One end of the horizontal plate 311 facing away from the fixed plate 2 is connected to the driving member 32. The driving member 32 includes a connecting plate 321 and a pushing cylinder 322. One end of the connecting plate 321 is connected to the horizontal plate 311, and the other end is connected to the telescopic section of the pushing cylinder 322. The pushing cylinder 322 is installed on the fixed base 1. The connecting plate 321 is an L-shaped plate.

[0035] In this embodiment, the side wall limiting block 222 and the coaxial upper limiting block 223 constitute an X-axis positioning structure, and the upper groove 221 provides Z-axis height constraint. The resulting positioning space makes the SFP optical module positioning more accurate. This multi-dimensional limiting structure eliminates any degree of freedom of the workpiece during the clamping process, fundamentally solving the problem of the pressure plate 312 not fitting tightly with the workpiece. The equidistantly arranged upper limiting blocks 223 form 15 parallel workpiece placement slots. With the synchronous clamping mechanism, a single operation can complete the clamping of a batch of products. Compared with traditional single-station manual clamping, it is more efficient. The cooperation between the movable groove 225 and the pressure plate 312 allows the pressure plate 312 to automatically fine-tune its angle during sliding. To accommodate minor assembly errors, the detachable pressure plate 312, with its standardized interface, and the L-shaped connecting plate 321, efficiently convert the vertical force of the cylinder 322 into the horizontal movement of the horizontal plate 311. The movable groove 225 formed by the lower limiting block 224 precisely guides the movement of the pressure plate 312, avoiding the risk of interference between the clamping mechanism and the workpiece or the fixed plate 2. The pressure plate 312 has floating space within the movable groove 225, which can generate a small displacement when encountering abnormal resistance, avoiding workpiece damage caused by hard collisions. In view of the easy scratch characteristics of the optical module shell, the contact surface of the pressure plate 312 is made of polyurethane material with a Shore hardness of 60A, eliminating the shell indentation and surface damage problems caused by traditional metal clamps.

[0036] To better understand this utility model, the following is combined with... Figures 1 to 6The technical solution of this utility model is described in detail as follows: The operator selects the corresponding dedicated fixing plate 2 according to the model of the optical module to be processed, aligns the fixing plate 2 horizontally with the mounting groove 11 on the fixing base 1, ensuring that the central strip hole 21 is aligned with the protrusion 12 in the mounting groove 11, and presses the fixing plate 2 vertically down so that the protrusion 12 is completely inserted into the central strip hole 21. At this time, the two side strip holes 21 are naturally located at the edge of the mounting groove 11. The fixing plate 2 is locked in the mounting groove 11 using simple buckles or quick-release bolts, completing the installation. The operator then places the pre-assembled SFP optical module base and small cover plate according to the direction markings, vertically placing each pre-assembled unit from above into the workpiece placement groove formed by the adjacent upper limiting block 223 and the upper groove 221. The side wall limiting block 222 and the coaxial upper limiting block 223 automatically constrain the position of the workpiece in the X-axis direction. 221 restricts the displacement of the workpiece in the Z-axis direction to ensure that all workpieces are at the same height. The standard fixing plate 2 can load 15 optical modules at the same time. The operator visually checks and confirms that all stations are in place. The operator manually pulls the hand lever valve of the control cylinder, and the piston rod extends outward, driving the L-shaped connecting plate 321 to move horizontally. The horizontal arm of the connecting plate 321 pushes the horizontal plate 311 to move forward along the movable channel 111. The horizontal plate 311 drives all the pressure plates 312 to slide forward synchronously in the movable groove 225. The front end of the pressure plate 312 contacts the edge of the small cover plate of the optical module and continues to apply stable pressure. The pressure plate 312 uses a polyurethane contact surface with a Shore hardness of 60A to apply pressure evenly without damaging the surface of the workpiece. The multi-axis screwdriver of the automatic screw machine simultaneously performs screw-locking operations on all stations. The pressure plate 312 maintains constant pressure during the screw-locking process to ensure that the small cover plate and the base are completely in contact.

Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
