Description

Technical Field

[0002] An optical module consists of optoelectronic devices, functional circuits, and optical interfaces. The optoelectronic devices include both transmitting and receiving parts. Simply put, the function of an optical module is to convert electrical signals into optical signals at the transmitting end, transmit them through optical fiber, and then convert the optical signals back into electrical signals at the receiving end. According to the packaging form, an optical module is an Ethernet transmission media conversion unit that interchanges short-distance twisted-pair electrical signals and long-distance optical signals. In many places, it is also called a photoelectric converter. During the manufacturing process of an optical module, its surface needs to be milled.

[0003] Chinese utility model CN222627344U proposes "a tooling fixture for optical modules". Although the device can also clamp optical modules, the clamping efficiency is low and it cannot clamp and process multiple products at the same time, resulting in poor dimensional consistency of batch products and easy burr residue. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide an internal support optical module clamping device to solve the technical problems of low clamping efficiency, inability to clamp multiple products simultaneously, poor dimensional consistency of subsequent processed products, and easy presence of burr residue in existing optical module processing clamping mechanisms.

[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 an internally supported optical module clamping device, comprising:

[0007] The base has several processing tables mounted on its top, and a limit post is set inside the processing table. The top of the processing table has multiple moving slots.

[0008] The clamping end includes a fixed plate and a movable plate corresponding to each of the plurality of movable slots. The fixed plate is mounted on the processing table and close to the movable slot. The movable plate is movably connected to the movable slot and its lower end is slidably connected to the limiting post. An inner support area is formed between one of the fixed plates and the movable plate.

[0009] The power mechanism includes a drive end and a connecting end. The drive end is located outside the processing table, and one end of the drive end extends into the processing table and is connected to the moving plate through the connecting end. It is used to adjust the distance between the moving plate and the fixed plate.

[0010] In some embodiments, the number of processing tables is at least two, and a slide rail is provided inside the processing table and on the base. A slider is slidably connected to the slide rail, and a connecting end is provided at the upper end of the slider.

[0011] In some embodiments, the lower end of the movable plate is connected to an extension plate, which is slidably connected to the limiting post.

[0012] In some embodiments, the number of the fixed plate and the movable plate is at least twelve.

[0013] In some embodiments, the number of drive ends is two, each drive end including a cylinder, the cylinder being mounted on the base, and the telescopic end of the cylinder extending into the processing table and connected to the connecting end.

[0014] In some embodiments, the connecting end includes a movable plate and a plurality of push blocks. The movable plate is disposed inside the processing table, and the slider is connected to its bottom. One end of the movable plate is connected to the telescopic end of the cylinder, and a plurality of push blocks that cooperate with the movable plate are arranged at equal intervals on the upper end of the movable plate.

[0015] In some embodiments, a metal plate is fixed to one end of the movable plate away from the cylinder, one end of the metal plate extends to the outside of the processing table, and a detection element that cooperates with the metal plate is also provided on the base.

[0016] In some embodiments, the detection element includes a mounting bracket and a metal detection sensor, the mounting bracket being mounted on the base, and the base being connected to a metal detection sensor that mates with the metal plate.

[0017] Compared with existing technologies, this utility model provides an internally supported optical module clamping device. By setting multiple processing tables and multiple fixed plates and movable plates on the processing tables, it can realize the synchronous clamping and processing of multiple optical modules, solving the problem of low efficiency caused by single-point clamping in existing technologies. The setting of the limiting post is coordinated with the internal structure of the processing table to provide precise guidance for the movable plate, ensuring the linear movement of the movable plate during clamping and avoiding the problem of uneven clamping caused by offset. An internal support area is formed between the fixed plate and the movable plate, avoiding the problem of stress concentration at the edge of the optical module caused by traditional external clamping, so that the clamping force is evenly distributed on the optical module. The surrounding area effectively prevents deformation or damage to the optical module during processing. The inner support area can automatically adjust according to the size of the optical module, and the spacing is precisely controlled by the power mechanism, allowing the device to adapt to various specifications of optical modules. The inner support clamping method avoids external force squeezing the edge of the optical module, resulting in a smoother edge after milling. This effectively solves the problem of burr residue that is easy to generate in traditional clamping methods, improving the product qualification rate. The drive end is located outside the processing table, which facilitates daily maintenance and troubleshooting. The connection end allows the drive end to precisely control the displacement of the moving plate, thereby accurately adjusting the distance between the fixed plate and the moving plate to meet the clamping requirements of different optical modules.

[0025] 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.

[0026] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an internal support type workpiece clamping device in one embodiment of the present utility model. An internal support type optical module clamping device includes a base 1, a plurality of processing tables 2 are installed on the top of the base 1, a limit post 13 is provided inside the processing table 2, and a plurality of moving slots 21 are opened on the top of the processing table 2.

[0027] The clamping end 3 includes a fixed plate 31 and a movable plate 32 corresponding to a plurality of movable slots 21. The fixed plate 31 is mounted on the processing table 2 and close to the movable slots 21. The movable plate 32 is movably connected in the movable slots 21 and its lower end is slidably connected to the limiting post 13. An inner support area is formed between one of the fixed plate 31 and the movable plate 32.

[0028] The power mechanism 4 includes a drive end 41 and a connecting end 42. The drive end 41 is located outside the processing table 2, and one end of the drive end 41 extends into the processing table 2 and is connected to the moving plate 32 through the connecting end 42. It is used to adjust the distance between the moving plate 32 and the fixed plate 31.

[0029] In this embodiment, by setting multiple processing tables 2, and on the processing tables 2, multiple fixed plates 31 and movable plates 32 are set, which enables the synchronous clamping and processing of multiple optical modules, solving the problem of low efficiency caused by single-point clamping in the prior art. The setting of the limiting post 13 is coordinated with the internal structure of the processing table 2 to provide precise guidance for the movable plate 32, ensuring the linear movement of the movable plate 32 during clamping, and avoiding the problem of uneven clamping caused by offset. An inner support area is formed between the fixed plate 31 and the movable plate 32, avoiding the problem of stress concentration at the edge of the optical module caused by traditional external clamping, so that the clamping force is evenly distributed around the optical module, effectively preventing the clamping force from being applied to the optical module. If the optical module deforms or is damaged during the process, the inner support area can be automatically adjusted according to the size of the optical module. The spacing is precisely controlled by the power mechanism 4, so that the device can be adapted to optical modules of various specifications. The inner support clamping method avoids the external force squeezing the edge of the optical module, making the edge smoother after milling. It effectively solves the problem of burr residue that is easy to be generated in traditional clamping methods, and improves the product qualification rate. The drive end 41 is set outside the processing table 2, which facilitates daily maintenance and troubleshooting. The connection end 42 enables the drive end 41 to precisely control the displacement of the moving plate 32, thereby precisely adjusting the distance between the fixed plate 31 and the moving plate 32 to meet the clamping requirements of different optical modules.

[0030] In one embodiment, please refer to Figure 1 - Figure 4 To improve the clamping efficiency of the moving plate 32 and the fixed plate 31 on the workpiece, the number of processing tables 2 is at least two. Inside any one of the processing tables 2, a slide rail 11 is provided on the base 1. A slider 12 is slidably connected to the slide rail 11, and a connecting end 42 is provided at the upper end of the slider 12. An extension plate 321 is connected to the lower end of the moving plate 32, and the extension plate 321 is slidably connected to the limiting post 13. The number of fixed plates 31 and moving plates 32 is at least twelve, and the number of driving ends 41 is... Two, the drive end 41 includes a cylinder 411, the cylinder 411 is mounted on the base 1, and the telescopic end of the cylinder 411 extends into the processing table 2 and is connected to a connecting end 42. The connecting end 42 includes a movable plate 421 and several push blocks 422. The movable plate 421 is set in the processing table 2, and a slider 12 is connected to its bottom. One end of the movable plate 421 is connected to the telescopic end of the cylinder 411. Several push blocks 422 that cooperate with the movable plate 32 are arranged at equal intervals on the upper end of the movable plate 421.

[0031] In this embodiment, two processing tables 2 are provided on the base 1, and each processing table 2 has a total of six moving slots 21. This allows the device to clamp twelve workpieces simultaneously. Each processing table 2 is equipped with an independent guide structure of slide rail 11 and slider 12, so that the movable plate 421 moves smoothly in a straight line under the drive of cylinder 411, effectively avoiding the problem of asynchronous movement of the movable plate 32 due to uneven load or friction. The movable plate 32 is not only subjected to force by the push block 422, but also by the extension plate 321 at the limiting post 1. The sliding mechanism 32 effectively suppresses wobbling, warping, or tilting of the moving plate 32 during clamping, maintaining high rigidity, especially during rapid movement of the cylinder 411, thus preventing clamping failure or damage to the optical module. The limiting post 13 acts as a rigid guide element in the vertical direction, ensuring that the extension plate 321 slides only axially, eliminating lateral displacement. This structure ensures that the moving plate 32 always moves parallel to the fixed plate 31, thereby guaranteeing a regular shape in the inner support area, applying uniform pressure to the inner wall of the optical module, and preventing localized stress concentration. Integrated into the lower end of the movable plate 32, it requires no additional installation space, saving structural volume and enhancing overall rigidity. It is particularly suitable for space-constrained automated production lines. This device can clamp 12 optical modules simultaneously. With the symmetrical drive of the dual cylinders 411, it can complete batch processing in one clamping, greatly improving output per unit time. The push blocks 422 are equidistantly arranged and correspond one-to-one with each movable plate 32, ensuring that the power output of the cylinders 411 is evenly distributed to each clamping unit. This avoids the problem of uneven clamping force caused by the difference in lever arm in traditional linkage mechanisms, so that all optical modules are subjected to the same clamping force, ensuring processing consistency. The movable plate 421, as an intermediate transmission component, directly converts the linear motion of the cylinders 411 into the synchronous translation of multiple push blocks 422, eliminating the need for complex gear, cam, or lever mechanisms and effectively reducing costs. There are seven push blocks 422, one more than the number of movable plates 32. This allows the movable plate 32 to move towards the fixed plate 31 when the cylinders 411 drive the movable plate 421 to retract.

[0032] In one embodiment, please refer to Figure 1 - Figure 5 To improve the accuracy of the moving position of the movable plate 421, a metal plate 423 is fixed to the end of the movable plate 421 away from the cylinder 411. One end of the metal plate 423 extends to the outside of the processing table 2. A detection element 5 that cooperates with the metal plate 423 is also provided on the base 1. The detection element 5 includes a mounting bracket 51 and a metal detection sensor 52. The mounting bracket 51 is mounted on the base 1, and the metal detection sensor 52 that cooperates with the metal plate 423 is connected to the base 1.

[0033] In this embodiment, the metal plate 423 is rigidly connected to the end of the movable plate 421 as a follow-up trigger element and moves synchronously with it. The metal detection sensor 52 is an inductive proximity switch and is fixed to the mounting bracket 51 on the base 1. It is used to sense whether the metal plate 423 has reached the preset position. When the metal plate 423 enters the sensor sensing area, the sensor outputs an electrical signal to indicate that the clamping action is completed or in place. If the metal plate 423 does not move in place, the machine tool self-checks and suspends processing until human intervention corrects it.

[0034] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail as follows: First, the optical module is placed in the inner support area composed of the fixed plate 31 and the movable plate 32. Then, the cylinder 411 is activated. The telescopic end of the cylinder 411 pushes the movable plate 421, causing the slider 12 at its lower end to move horizontally on the slide rail 11. This drives the push block 422 to push the extension plate 321 at the lower end of the movable plate 32 to be smoothly guided along the limiting post 13. At the same time, the movable plate 32 slides in the opposite direction along the moving groove 21 towards the fixed plate 31, thereby providing two opposite forces to the inner wall of the optical module, so that the optical module is in a clamping state. When the movable plate 421 moves to the position, the metal plate 423 at its end triggers the metal detection sensor 52 on the base 1. The external control terminal confirms that the clamping is completed and starts the external processing equipment to start the edge milling operation. After the processing is completed, the cylinder 411 retracts, the movable plate 32 resets, and the workpiece is released, thereby completing an efficient, safe, and automated clamping, processing, and reset cycle.

[0035] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. 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.
