Abstract
Description
Technical Field
[0001] This application relates to the technical field of optical module testing, and in particular to a clamping structure for optical module testing. Background Technology
[0002] Optical modules are the core components of optical fiber communication systems, responsible for converting electrical signals to optical signals. Modules focus on photoelectric conversion, while modulators are used for signal encoding and amplifiers for signal enhancement. In short, they are the "bridge" of optical communication, achieving efficient signal conversion through precise optoelectronic devices to support modern high-speed data transmission networks. With technological iteration, they are evolving towards higher speeds and lower power consumption.
[0003] Currently, to ensure the factory pass rate of optical modules, testing equipment is required during the production process. Before testing, the optical modules need to be fixed on a clamping structure and then moved within a specific path by the clamping structure. This allows the testing equipment set up along that path to perform the testing operation on the optical modules.
[0004] In related technologies, since the optical module needs to be moved along a specific path after being clamped and fixed during the testing process, the traditional method uses a motor and lead screw to drive it. This results in the motor frequently driving the lead screw to rotate in both forward and reverse directions during the testing process. Frequent forward and reverse rotation can easily lead to motor overheating, mechanical wear and shortened lifespan. At the same time, frequent failures of the motor and lead screw require downtime for maintenance, increasing equipment operation and maintenance costs and restricting continuous operation in large-scale testing scenarios. Utility Model Content
[0005] To address the problem that frequent forward and reverse rotation of the motor is required when driving the device via an electric motor, which can easily damage the motor, this application provides a clamping structure for optical module detection.
[0006] The clamping structure for optical module testing provided in this application adopts the following technical solution:
[0007] A clamping structure for optical module detection, comprising:
[0008] A fixed base is provided on one side of the fixed base. A slider is slidably engaged in the sliding groove. A support tray is fixed on one side of the slider. A clamping plate is slidably connected in the support tray, and two are symmetrically arranged. An optical module is engaged between two adjacent clamping plates. A clamping spring is provided between the clamping plate and the support tray.
[0009] A driving mechanism is used to drive the optical module to move. The driving mechanism is mounted on a slider and includes a limiting cylinder, a support rod, a roller, a driving roller, and an adjusting disk. The limiting cylinder is rotatably connected to the slider and has a slot at its bottom. One end of the support rod is slidably engaged in the slot. The roller is rotatably connected to the other end of the support rod. The driving roller is rotatably connected to one side of the fixed base and located at the bottom of the sliding groove. The roller rolls against the driving roller. The adjusting disk is coaxially rotatably connected to the top of the limiting cylinder.
[0010] An adjustment mechanism is provided for adjusting the angle of the roller, and the adjustment mechanism is located on top of the slider.
[0011] By adopting the above technical solution, movement is achieved through friction transmission between the rollers and the drive roller in the drive mechanism. The direction of movement can be changed by adjusting the contact angle between the rollers and the drive roller using an adjustment mechanism. This eliminates the need for motor reversal, simplifies control logic, and reduces energy consumption. It avoids the overheating and mechanical wear problems caused by frequent forward and reverse rotation of the motor in traditional screw drives, significantly improving equipment lifespan. Furthermore, the roller assembly can be replaced individually after wear, resulting in lower maintenance costs compared to screw drive systems that require complete disassembly. The friction transmission response speed is also superior to screw drives, supporting rapid switching of detection points during optical module movement. This solution innovatively solves the reliability bottleneck of traditional drive methods through mechanical transmission, combining high efficiency, low power consumption, and easy maintenance, making it suitable for continuous detection requirements of optical modules.
[0012] Optionally, the driving mechanism further includes a first crossbar, a second crossbar, and a first return spring. The first crossbar is horizontally fixed to the outer wall of the limiting cylinder, the second crossbar is horizontally fixed to the outer wall of the adjusting disc, and the first return spring is connected between the first crossbar and the second crossbar.
[0013] By adopting the above technical solution, the elastic force of the first return spring is used to pull the first crossbar and the second crossbar, thereby realizing the synchronous adjustment of the angle of the limiting cylinder and the roller.
[0014] Optionally, the adjustment mechanism includes a positioning plate, an abutment plate, and a second reset spring. The top of the slider is provided with a rectangular slot. The positioning plate is slidably engaged in the rectangular slot. The abutment plate is fixed on the outer wall of the limiting cylinder and abuts against one side of the positioning plate. The second reset spring is disposed in the rectangular slot, and one end is fixed to the positioning plate.
[0015] By adopting the above technical solution, the elastic force of the second reset spring is used to push the positioning plate to limit the abutment plate, thereby achieving the limiting effect on the limiting cylinder.
[0016] Optionally, the adjustment mechanism further includes a first stop bar, which is fixed at the top four corners of the slider and is arranged symmetrically with four of them, two of which are located on both sides of the first crossbar and the other two are located on both sides of the second crossbar.
[0017] By adopting the above technical solution, the rotation angles of the first crossbar and the second crossbar are limited by the first stop bar.
[0018] Optionally, the adjustment mechanism further includes a second stop lever, which is disposed on the top of the fixed base, and at least two second stop levers are provided, with the second crossbar located between two adjacent second stop levers.
[0019] By adopting the above technical solution, when the second stop bar comes into contact with the second crossbar, it can deflect, and the first crossbar can simultaneously drive the limiting cylinder to deflect.
[0020] Optionally, the top of the fixing seat is provided with a screw hole, and several screw holes are provided at equal intervals. The bottom of the second stop is provided with a threaded rod, which is threaded into the screw hole.
[0021] By adopting the above technical solution, the position of the second stop on the fixed base can be adjusted to a certain extent according to the actual situation.
[0022] Optionally, a third return spring is provided at the top of the support rod, and one end of the third return spring abuts against the limiting cylinder.
[0023] By adopting the above technical solution, the elastic force of the third return spring is used to make the roller tightly abut against the drive roller.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] Movement is achieved through friction transmission between rollers and drive rollers in the drive mechanism. The direction of movement can be changed by adjusting the contact angle between the rollers and drive rollers using an adjustment mechanism. No motor reversal is required, simplifying the control logic and reducing energy consumption. This avoids the overheating and mechanical wear problems caused by frequent forward and reverse rotation of the motor in traditional screw drives, significantly extending the equipment's lifespan. Furthermore, the roller assembly can be replaced individually after wear, resulting in lower maintenance costs compared to screw drive systems that require complete disassembly. Friction transmission also offers a faster response speed than screw drives, supporting rapid switching of detection points during optical module movement. This solution innovatively solves the reliability bottleneck of traditional drive methods through mechanical transmission, combining high efficiency, low power consumption, and easy maintenance. It is suitable for continuous detection requirements of optical modules. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0034] This application discloses a clamping structure for optical module detection.

The fixed base 1 has a sliding groove 2 on one side, within which the slider 3 is slidably engaged. A support tray 4 is fixed to one side of the slider 3, and two clamping plates 5 are slidably connected within the support tray 4, arranged symmetrically. An optical module 6 is engaged between two adjacent clamping plates 5, and a clamping spring 7 is positioned between the clamping plate 5 and the support tray 4. The drive mechanism 8, used to move the optical module 6, is located on the slider 3. The adjustment mechanism 9 is located on the top of the slider 3, utilizing the friction between the roller 83 and the drive roller 84 in the drive mechanism 8. Friction drive enables movement, and the direction of movement can be changed by adjusting the contact angle between the roller 83 and the drive roller 84 using the adjustment mechanism 9. No motor reversal is required, simplifying the control logic and reducing energy consumption. It avoids the overheating and mechanical wear problems caused by frequent forward and reverse rotation of the motor in traditional screw drive, significantly improving the equipment life. At the same time, the roller assembly can be replaced separately after wear, and the maintenance cost is lower than that of the screw drive system which requires complete disassembly. Moreover, the friction drive has a faster response speed than the screw drive, and supports the rapid switching of detection points of the optical module during movement. This solution solves the reliability bottleneck of traditional drive methods through mechanical transmission innovation, and has the characteristics of high efficiency, low power consumption, and easy maintenance. It is suitable for the continuous detection needs of optical modules.
[0037] Specifically, the drive mechanism 8 includes a limiting cylinder 81, a support rod 82, a roller 83, a drive roller 84, and an adjusting plate 85. The limiting cylinder 81 is rotatably connected to the slider 3, and a slot is provided at the bottom of the limiting cylinder 81. One end of the support rod 82 is slidably engaged in the slot, and the roller 83 is rotatably connected to the other end of the support rod 82. The drive roller 84 is rotatably connected to one side of the fixed seat 1 and is located at the bottom of the sliding groove 2. The roller 83 rolls against the drive roller 84. The adjusting plate 85 is coaxially rotatably connected to the top of the limiting cylinder 81.
[0038] Reference Figure 3 In this embodiment of the application, the drive mechanism 8 further includes a first crossbar 86, a second crossbar 87, and a first return spring 88. The first crossbar 86 and the second crossbar 87 are pulled by the elastic force of the first return spring 88, thereby realizing the synchronous adjustment of the angle of the limiting cylinder 81 and the roller 83.
[0039] The first crossbar 86 is horizontally fixed on the outer wall of the limiting cylinder 81, the second crossbar 87 is horizontally fixed on the outer wall of the adjusting disc 85, and the first reset spring 88 is connected between the first crossbar 86 and the second crossbar 87.
[0040] In this embodiment, the adjustment mechanism 9 includes a positioning plate 91, an abutment plate 92, and a second return spring 93. The elastic force of the second return spring 93 is used to push the positioning plate 91 to limit the abutment plate 92, thereby achieving the limiting effect on the limiting cylinder 81.
[0041] The top of the slider 3 is provided with a rectangular slot, the positioning plate 91 is slidably engaged in the rectangular slot, the abutment plate 92 is fixed on the outer wall of the limiting cylinder 81 and abuts against one side of the positioning plate 91, and the second reset spring 93 is provided in the rectangular slot, with one end fixed to the positioning plate 91.
[0042] In this embodiment of the application, regarding the adjustment mechanism 9, the adjustment mechanism 9 further includes a first stop bar 94. The first stop bar 94 is fixed at the top four corners of the slider 3 and is arranged symmetrically. Two of the first stop bars 94 are located on both sides of the first crossbar 86, and the other two first stop bars 94 are located on both sides of the second crossbar 87. The first stop bars 94 are used to limit the rotation angle of the first crossbar 86 and the second crossbar 87 respectively.
[0043] Specifically, the adjustment mechanism 9 also includes a second stop lever 95, which is located on the top of the fixed base 1, and there are at least two second stop levers 95. The second crossbar 87 is located between two adjacent second stop levers 95.
[0044] In this embodiment, when the second stop 95 contacts the second crossbar 87, it can deflect, and the first crossbar 86 simultaneously drives the limiting cylinder 81 to deflect.
[0045] Reference Figure 4 The top of the fixed base 1 is provided with screw holes, and several screw holes are evenly spaced. The bottom of the second stop 95 is provided with a threaded rod, which is threaded into the screw holes. The position of the second stop 95 on the fixed base 1 can be adjusted to a certain extent according to the actual situation.
[0046] Reference Figure 5 In this embodiment of the application, a third return spring 10 is provided at the top of the support rod 82. One end of the third return spring 10 abuts against the limiting cylinder 81. The elastic force of the third return spring 10 enables the roller 83 to abut tightly against the drive roller 84.
[0047] The implementation principle of a clamping structure for optical module detection in this application embodiment is as follows: First, the external driving device is connected to the driving roller 84. At this time, the driving roller 84 rotates and drives the roller 83 to move in conjunction. Since there is an angle between the roller 83 and the driving roller 84, the roller 83 can drive the slider 3 to slide in the sliding groove 2. When the second crossbar 87 abuts against the second stop bar 95, the second crossbar 87 drives the adjusting plate 85 to deflect. At this time, under the action of the first reset spring 88, the first crossbar 86 is pulled and the limiting cylinder 81 is driven to rotate. Then, the roller 83 is driven to deflect through the support rod 82, so that the angle between the roller 83 and the driving roller 84 changes, thereby enabling the optical module 6 to move in the opposite direction.
[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
