Description

Technical Field

[0001] This utility model relates to the field of optical module manufacturing technology, specifically to an optical module reciprocating insertion and removal mechanism. Background Technology

[0002] In the production and testing of optical communication equipment, the stability of the connection between the optical module and the equipment interface is crucial to communication quality. To ensure the reliability of the optical module under long-term use and frequent insertion / removal scenarios, it is necessary to simulate actual working conditions through reciprocating insertion / removal tests to verify its mechanical strength, electrical contact performance, and signal transmission stability. Since optical module interfaces often use precision pins or optical coupling structures, alignment accuracy must be strictly ensured during insertion and removal.

[0003] Existing optical module insertion and removal testing machines typically have the drive unit fixed to the worktable, providing power and stroke control for the insertion and removal actions. The main body of the testing machine and the optical module fixing components are located near the drive unit. To facilitate quick replacement and positioning of optical modules, the insertion and removal head needs to be equipped with a dedicated base, using slots, positioning pins, and other structures to achieve detachable fixing of the module.

[0004] However, this distributed installation structure, with the accumulation of assembly gaps between various components such as the drive unit, workbench, plug-in head base, and test machine body, will create a large overall error, increasing the difficulty of subsequent positional accuracy adjustment. Utility Model Content

[0005] The purpose of this utility model is to provide a reciprocating insertion and removal mechanism for optical modules. By setting a base that is compatible with the test port, the optical module is fixed by the insertion and removal component. The insertion and removal guide of the insertion and removal component is set as a guide groove and a guide block. The guide groove is directly opened in the middle of the base, so that the optical module test end can be aligned with the test port by pushing the insertion and removal component into the base. The external insertion and removal drive is not directly connected to the insertion and removal component, so there is no need to take the installation error of the external drive into account. This replaces the traditional method of fixing the insertion and removal component and the drive and then aligning it with the test port, which can reduce the difficulty of precision adjustment caused by the superposition of errors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reciprocating insertion and removal mechanism for an optical module, comprising a testing machine and a base fixed outside the testing port of the testing machine. One end of the base is provided with an extension plate that can extend into the testing port. The base is provided with a plug-in component for inserting into the testing port. The plug-in component is provided with a limiting structure for fixing the optical module. The upper surface of the base is provided with a groove of equal width for inserting the plug-in component. The groove of equal width is provided with a guide structure for guiding the insertion and removal of the plug-in component. A material ejection structure is installed below the testing machine to disengage the plug-in component from the testing port.

[0007] Preferably, the guiding structure includes a guide block, which is integrally formed on the bottom of the insert, and a guide groove for inserting the guide block is formed in the middle of the equal-width groove.

[0008] Preferably, the ejection structure includes an electric push rod, the telescopic end of which is fixed with a push block, the top of which is located in a guide groove, and the lower surface of the base is provided with an integrally formed thickened part that can restrict the horizontal movement of the push block.

[0009] Preferably, the limiting structure includes a slot on one side of the plug-in component, the optical module is inserted into the slot, the upper surface of one end of the plug-in component is provided with a through groove for exposing the test point of the optical module, the other end of the plug-in component is provided with an end cap that can restrict the optical module in the slot, and a snap-fit ​​structure is provided between the end cap and the plug-in component.

[0010] Preferably, the snap-fit ​​structure includes a protrusion, which is integrally formed in the inner cavity of the cap, and the upper and lower surfaces of the plug-in component are provided with slots, and the protrusion snaps into the slots.

[0011] Preferably, the optical module reciprocating insertion and removal mechanism further includes a pressing structure capable of limiting the insertion and removal component within the base;

[0012] The pressing structure includes a pressure plate and four sets of mounting seats fixed to the lower surface of the pressure plate. The mounting seats are equipped with ball bearings, and the four sets of ball bearings are arranged in a matrix.

[0013] Preferably, the pressing structure further includes a spring, and both sides of the base are fixed with fixing plates by screws. Both ends of the upper surface of the fixing plate are fixed with fixing rods. The fixing rods pass through the pressure plate and are slidably connected to the pressure plate. A limit block is welded to the top of the fixing rod. The spring is sleeved on the outer wall of the fixing rod. The top end of the spring is fixedly connected to the limit block, and the bottom end of the spring is fixedly connected to the pressure plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model fixes the base to the outside of the test port of the testing machine, and the base adopts an integrated molding design. The equal width groove and the guide groove are directly opened on the base. The plug-in component is guided by the cooperation of the guide block and the guide groove, so that the plug-in and plug-out action relies entirely on the inherent guide trajectory of the base. There is no need to consider the installation error of the external drive device, avoiding the error superposition problem caused by the fixed connection between the plug-in component and the drive device in the traditional structure, and reducing the difficulty of precision adjustment.

[0016] 2. The thickened part of the base of this utility model provides support and limit for the push block of the ejection structure, ensuring that the pushing force of the electric push rod can act on the insertion and removal parts. The pressing structure uses the elastic force of the spring to make the ball under the pressure plate closely contact the insertion and removal parts, ensuring the positional stability of the insertion and removal parts during the insertion and removal process. In the limiting structure, the optical module is inserted through the slot and fixed by the end cover and the snap-fit ​​structure, which is convenient for disassembly and assembly and facilitates the quick replacement of the optical module.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a reciprocating insertion and removal mechanism for an optical module, including a testing machine 1 and a base 2 fixed outside the testing port of the testing machine 1. One end of the base 2 is provided with an extension plate 3 that can extend into the testing port. The base 2 is provided with a plug-in component 4 for inserting into the testing port. The plug-in component 4 is provided with a limiting structure 5 for fixing the optical module. The upper surface of the base 2 is provided with a groove 6 of equal width for inserting the plug-in component 4. The groove 6 is provided with a guide structure 7 for guiding the insertion and removal of the plug-in component 4. The lower part of the testing machine 1 is provided with a material ejection structure 8 for disengaging the plug-in component 4 from the testing port.

[0030] The guide structure 7 includes a guide block 701, which is integrally formed on the bottom of the insert 4. The equal width groove 6 has a guide groove 702 in the middle for the guide block 701 to be inserted.

[0031] The plug-in component 4 with the optical module installed is placed into the equal-width slot 6 of the base 2. Since the width of the equal-width slot 6 is equal to the width of the plug-in component 4 and the test port, and the equal-width slot 6 is preset to be a through slot 502 aligned with the test end of the test machine 1, when the external drive device pushes the end cap 503 of the plug-in component 4, the guide block 701 at the bottom of the plug-in component 4 slides along the guide slot 702 in the equal-width slot 6, so that the plug-in component 4, carrying the optical module, is pushed into the test port and automatically aligned with the test end of the test machine 1.

[0032] The cooperation between the equal-width slot 6 and the guide slot 702 provides an inherent guide trajectory for the plug-in component 4, avoiding the error accumulation caused by the fixed connection between the plug-in component 4 and the external drive device in traditional structures. Alignment is achieved through the dimensional matching of the mechanical structure itself, reducing reliance on the installation accuracy of the external drive device and minimizing the difficulty of manual adjustment.

[0033] The ejection structure 8 includes an electric push rod 801, and a push block 802 is fixed to the telescopic end of the electric push rod 801. The top end of the push block 802 is located in the guide groove 702. The lower surface of the base 2 is provided with an integrally formed thickened part 803 that can restrict the horizontal movement of the push block 802.

[0034] When it is necessary to remove the plug-in component 4, the electric push rod 801 below the test machine 1 is activated. Its telescopic end drives the push block 802 to move along the guide groove 702. The top of the push block 802 contacts the guide block 701 at the bottom of the plug-in component 4 and applies a pushing force, causing the plug-in component 4 to slide in the opposite direction along the guide groove 702 and disengage from the test port. The thickened part 803 on the lower surface of the base 2 restricts the horizontal movement of the push block 802 to ensure that the pushing force is accurately applied to the guide block 701.

[0035] The limiting structure 5 includes a slot 501 opened on one side of the plug-in component 4, the optical module is inserted into the slot 501, the upper surface of one end of the plug-in component 4 is provided with a through groove 502 for exposing the test point of the optical module, and the other end of the plug-in component 4 is provided with an end cap 503 that can restrict the optical module in the slot 501, and a snap-fit ​​structure is provided between the end cap 503 and the plug-in component 4.

[0036] The snap-fit ​​structure includes a protrusion 504, which is integrally formed in the inner cavity of the cap. The upper and lower surfaces of the plug-in component 4 are provided with slots 505, and the protrusion 504 is snapped into the slots 505.

[0037] like Figure 5 , Figure 6 As shown, the optical module is inserted into the slot 501 on one side of the plug-in component 4, and the end cover 503 is placed on top. The protrusion 504 inside the end cover 503 engages with the slots 505 on the upper and lower surfaces of the plug-in component 4, thus confining the optical module within the slot 501. At the same time, the through slot 502 at one end of the plug-in component 4 exposes the test points of the optical module, ensuring that it can contact the test end of the testing machine 1 during testing. The engagement structure between the slot 501 and the end cover 503 enables quick replacement of the optical module.

[0038] The optical module reciprocating plug-in mechanism also includes a pressing structure 9 that can limit the plug-in component 4 within the base 2;

[0039] The pressing structure 9 includes a pressure plate 901 and four sets of mounting seats 902 fixed on the lower surface of the pressure plate 901. The mounting seats 902 are equipped with ball bearings 903, and the four sets of ball bearings 903 are arranged in a matrix.

[0040] The pressing structure 9 also includes a spring 904. Both sides of the base 2 are fixed with fixing plates 905 by screws. Both ends of the upper surface of the fixing plate 905 are fixed with fixing rods 906. The fixing rods 906 pass through the pressure plate 901 and are slidably connected with the pressure plate 901. The top of the fixing rod 906 is welded with a limit block 907. The spring 904 is sleeved on the outer wall of the fixing rod 906. The top end of the spring 904 is fixedly connected to the limit block 907, and the bottom end of the spring 904 is fixedly connected to the pressure plate 901.

[0041] The fixing plates 905 on both sides of the base 2 are connected to the pressure plate 901 via the fixing rod 906. The elastic force of the spring 904 causes the ball bearings 903 on the lower surface of the pressure plate 901 to make close contact with the upper surface of the insert / removable part 4, applying downward pressure to the insert / removable part 4 during the insertion / removal process. Through the elastic pressure of the spring 904 and the rolling friction of the ball bearings 903, the positional stability of the insert / removable part 4 within the equal-width groove 6 is ensured, preventing up-and-down wobbling from affecting the alignment accuracy. At the same time, the friction during insertion / removal is reduced, ensuring smooth insertion / removal.

[0042] In use, insert the optical module to be tested into the slot 501 on one side of the plug-in component 4, so that the test point of the optical module corresponds to the through slot 502 on the upper surface of one end of the plug-in component 4, ensuring that the test point is exposed. Then, fasten the end cap 503 onto the other end of the plug-in component 4. The end cap 503 is engaged with the slots 505 on the upper and lower surfaces of the plug-in component 4 through the protrusion 504 in the inner cavity of the end cap 503, so that the optical module is stably confined in the slot 501.

[0043] The plug-in component 4 with the optical module installed is placed into the equal-width slot 6 of the base 2, so that the guide block 701 at the bottom of the plug-in component 4 is inserted into the guide groove 702 in the middle of the equal-width slot 6. The external push drive device acts on the end cap 503 of the plug-in component 4, pushing the plug-in component 4 to move towards the test port along the trajectory of the equal-width slot 6 and the guide groove 702. Since the width of the equal-width slot 6 matches the width of the plug-in component 4 and the test port, and the equal-width slot 6 is preset to be a through slot 502 that aligns with the test end of the test machine 1, after the plug-in component 4 is pushed into the test port, the test point of the optical module will automatically align with the test end of the test machine 1, completing the insertion action.

[0044] When the test is completed and the plug-in part 4 needs to be removed, the electric push rod 801 below the test machine 1 is activated. Its telescopic end drives the push block 802 to move along the guide groove 702. The top of the push block 802 contacts the guide block 701 at the bottom of the plug-in part 4 and applies a pushing force, causing the plug-in part 4 to slide in the opposite direction along the guide groove 702 and disengage from the test port. At the same time, the elastic force of the spring 904 in the pressing structure 9 applies downward pressure to the plug-in part 4 through the ball bearing 903 below the pressure plate 901, ensuring that the plug-in part 4 always moves along the guide trajectory during the material removal process and preventing shaking.

[0045] An external drive device pushes the device toward the test port, while the electric push rod 801 pushes it in the opposite direction, alternating to achieve a reciprocating insertion and removal test.
