Description

Technical Field

[0001] This utility model relates to the field of optical module testing equipment technology, and in particular to an optical module height testing mechanism. Background Technology

[0002] Currently, optical module housings are manufactured using die casting. However, this die casting process results in inconsistent housing dimensions, necessitating dimensional inspection at different locations to ensure compliance with design standards. Conventional methods utilize calipers and micrometers, which are insufficient for accurately measuring the complex structural features of the housing. Furthermore, contact-based measurements can damage tools, reducing accuracy. In addition, manual inspection is inefficient, relies heavily on personal experience, and is insufficient to meet the dimensional inspection requirements of optical modules. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to propose an optical module height detection mechanism that can perform dimensional detection at different positions of the optical module and can achieve continuous dimensional detection of the optical module in a non-contact manner, reducing manual intervention, improving detection efficiency and accuracy, effectively meeting the dimensional detection requirements of optical modules, and demonstrating strong practicality.

[0004] The technical solution of this utility model is implemented as follows: an optical module height detection mechanism, including a turntable, a rotary driver, and a height detection device;

[0005] The turntable has several placement areas for placing optical modules;

[0006] Each placement area on the turntable is equipped with a pressing component; the pressing component is used to press the optical module onto the turntable.

[0007] The rotary driver is used to drive the turntable to rotate around its own central axis, so as to drive the sequential passage of the placement area through the detection station;

[0008] The height detection device is arranged corresponding to the detection station and includes a base and a detection unit;

[0009] The base is positioned above the turntable;

[0010] Several sets of the detection units are spaced apart on the base; each detection unit includes a first adjusting block, a second adjusting block, a micrometer screw gauge, and a distance measuring sensor.

[0011] The first adjusting block is slidably disposed on the base in a first direction on the horizontal plane; the second adjusting block is slidably disposed on the first adjusting block in a second direction on the horizontal plane; the micrometer is disposed on the first adjusting block and has a measuring head that moves in the second direction and abuts against the second adjusting block;

[0012] The ranging sensor is mounted on the second adjusting block and has a measuring end facing the turntable.

[0013] Furthermore, the optical module height detection mechanism also includes a displacement drive mechanism for driving the seat to move up and down.

[0014] Furthermore, the second direction is defined as the length direction of the placement area when in the detection station; the displacement driving mechanism is also used to drive the seat to move along the second direction.

[0015] Furthermore, the detection units are arranged at intervals in the vertical and horizontal directions.

[0016] Furthermore, the turntable has a square structure; the placement areas are distributed at the four corners of the turntable; there are two inspection stations; and a height detection device is arranged for each inspection station.

[0017] Furthermore, the two sets of height detection devices share the same base.

[0018] Furthermore, the pressing component includes a pressing driver and a contact head; the contact head is disposed above the placement area and has a pressing state with a vertical distance between it and the placement area and a clearance state away from the placement area;

[0019] The pressure driver is connected to the contact head and is used to drive the contact head to switch between a pressure state and a clearance state, and to drive the contact head to move up and down toward or away from the placement area in the pressure state.

[0020] Furthermore, the pressure driver is a rotary pressure cylinder; the contact head is disposed on the drive end of the rotary pressure cylinder.

[0021] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0022] 1. This utility model, through the use of a pressing component, can press the optical module down onto the placement area to fix it in place. Through the use of a turntable, the optical module can be continuously transported to the inspection station for testing. Through the use of a detection device, a distance sensor can be used to detect the height of the optical module on the placement area. Specifically, by using a first adjusting block to slide along a first direction and a second adjusting block to slide along a second direction, the position of the distance sensor can be coarsely adjusted. And through the use of a micrometer screw gauge, the position of the distance sensor in the second direction can be finely adjusted. The combination of these methods enables dimensional detection at different positions of the optical module, and allows for continuous dimensional detection of the optical module in a non-contact manner, reducing manual intervention, increasing detection efficiency and accuracy, effectively meeting the dimensional detection requirements of optical modules, and demonstrating strong practicality.

[0023] 2. This utility model, through the use of a pressing component, enables the automatic pressing and fixing of the optical module in the placement area. The contact head can switch between a pressing state and an avoidance state. When the contact head is in the avoidance state, it is offset from the placement area, so as not to interfere with the process of loading and unloading the optical module into and out of the placement area, effectively meeting the loading requirements of the optical module and demonstrating strong practicality.

[0033] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0034] like Figure 1-7 The diagram illustrates a height detection mechanism for optical modules according to this embodiment. This mechanism is used to detect the housing of optical modules. The height detection mechanism includes a base, a turntable 1, a rotary driver 12, and a height detection device. The central axis of the turntable 1 is mounted on the base via bearings, allowing the turntable 1 to rotate around its own central axis. The central axis of the turntable 1 extends vertically. Several placement areas 11 for placing optical modules are arranged on the turntable 1. Detection stations are arranged beside the turntable 1. The rotary driver 12 is connected to the central axis of the turntable 1 and drives the turntable 1 to rotate around its own central axis, causing the placement areas 11 to sequentially pass through the detection stations. The rotary driver 12 is a conventional component of the prior art, preferably a stepper motor.

[0035] A pressing assembly 2 is installed on the turntable 1 corresponding to each placement area 11. This pressing assembly 2 is used to press the optical module onto the turntable 1 to fix the optical module. Specifically, the pressing assembly 2 includes a pressing driver 22 and a contact head 21. The contact head 21 is made of rubber. The contact head 21 is movably arranged above the placement area 11, having a pressing state with a vertical distance between it and the placement area 11, and a clearance state away from the placement area 11. In the pressing state, the contact head 21 moves vertically to have a pressing position and a releasing position in the vertical direction. In the pressing position, the contact head 21 is close to the placement area 11, allowing the optical module to be clamped between the contact head 21 and the turntable 1, thus fixing the optical module. When the contact head 21 is in the aforementioned release position, the contact head 21 moves away from the placement area 11 to release the optical module. When the aforementioned contact head 21 is in the avoidance state, the contact head 21 is deviated from the placement area 11, and an unobstructed space is formed above the placement area 11 to facilitate the loading and unloading of optical modules.

[0036] The aforementioned pressure actuator 22 is connected to the contact head 21 to drive the contact head 21 to switch between a pressure state and a clearance state, and to drive the contact head 21 up and down towards or away from the placement area 11 in the pressure state, thereby switching between the aforementioned pressing position and releasing position. In a specific structural design, the pressure actuator 22 drives the contact head 21 to rotate around a central axis to switch between the pressure state and the clearance state. This central axis extends vertically so that the contact head 21 can rotate in a horizontal plane, thereby switching between the pressure state and the clearance state. The pressure actuator 22 is preferably a conventional rotary pressure cylinder. The contact head 21 is mounted and fixed on the drive end of the pressure actuator 22. The rotary pressure cylinder performs rotational and lifting actions, thereby performing corresponding actions on the contact head 21.

[0037] In this embodiment, the aforementioned height detection device is arranged at the corresponding detection station, including a base 3 and a detection unit 4. The base 3 is positioned above the turntable 1. Several sets of detection units 4 are spaced apart on the base 3. The detection unit 4 includes a first adjusting block 41, a second adjusting block 42, a micrometer 44, and a distance sensor 43. The first adjusting block 41 is slidably arranged on the base 3 along a first direction on a horizontal plane via a slide rail. In this embodiment, the first adjusting block 41 is tightly fitted with the slide rail to provide a certain degree of damping when sliding on the slide rail. The aforementioned second adjusting block 42 is slidably arranged on the first adjusting block 41 along a second direction on a horizontal plane via a slide rail, and the second adjusting block 42 is tightly fitted with the slide rail to provide a certain degree of damping when sliding on the slide rail. The aforementioned micrometer 44 is fixedly installed on the first adjusting block 41, and has a measuring head that moves along the second direction and abuts against the second adjusting block 42. By adjusting the position of the micrometer head, the position of the second adjusting block 42 in the second direction can be precisely adjusted. The second direction is defined as the length direction of the placement area 11 (i.e., the length direction of the optical module) when it is in the detection station. The first direction is defined as the width direction of the placement area 11 (i.e., the width direction of the optical module) when it is in the detection station. The aforementioned distance sensor 43 is a prior art laser distance sensor. This distance sensor 43 is fixed to the second adjustment block 42 via a connecting plate 45 and has a measuring end facing the turntable 1. When the placement area 11 moves to the detection station, the measuring end of the distance sensor 43 is arranged facing the placement area 11 to measure the distance from the housing of the optical module to the measuring end. This distance value is converted into the height value of the housing through calculation. Through the above structural design, when the positions of the first adjustment block 41 and the second adjustment block 42 are adjusted, the position of the distance sensor 43 in the first direction and the second direction can be adjusted within a certain range. And the position of the distance sensor 43 in the second direction can be precisely adjusted by using a micrometer screw gauge 44.

[0038] In this embodiment, eight sets of the aforementioned detection units 4 are arranged for each detection station. These eight sets of detection units 4 are arranged at intervals in the vertical and horizontal directions to save assembly space and to detect different positions on the housing of the optical module.

[0039] In this embodiment, the turntable 1 has a square structure. The placement areas 11 are distributed at the four corners of the turntable 1. When the turntable 1 rotates 180° in a single rotation, it can move the two placement areas 11 to the testing station. There are two testing stations, each equipped with a height detection device to simultaneously detect the optical modules on the two placement areas 11 on the turntable 1. The two sets of height detection devices share the same base 3 to save manufacturing costs.

[0040] A displacement drive mechanism 5 is installed on the base. This displacement drive mechanism 5 is used to drive the seat 3 to move up and down, and to drive the seat 3 to move along a second direction. The displacement drive mechanism 5 is a conventional device of the prior art, which includes a horizontal drive mechanism capable of moving along the second direction and a vertical up-and-down movement mechanism. The vertical movement mechanism is arranged on the horizontal drive mechanism. The seat 3 is connected to the vertical movement mechanism. Through the cooperation of the vertical movement mechanism and the horizontal drive mechanism, the seat 3 can be driven to move, thereby driving the height detection device to move.

[0041] In practical use, the optical module is loaded onto the placement area 11 on the turntable 1. The pressure driver 22 switches the contact head 21 from a clearance state to a pressing state, then drives the contact head 21 downwards to contact and press against the optical module, thus fixing the optical module onto the turntable 1. The turntable 1 rotates to move the optical module to the inspection station. A distance sensor 43 is used to detect the height of different positions of the optical module's housing on the placement area 11. Specifically, the position of the distance sensor 43 can be coarsely adjusted by pushing the first adjusting block 41 along the first direction and the second adjusting block 42 along the second direction. The position of the distance sensor 43 can be finely adjusted in the second direction by turning the micrometer screw gauge 44, thus achieving precise positioning of the distance sensor 43. This combination of methods enables dimensional detection of different positions of the optical module and allows for continuous dimensional detection of the optical module in a non-contact manner, reducing manual intervention, increasing detection efficiency and accuracy, effectively meeting the dimensional detection requirements of optical modules, and demonstrating strong practicality.
