Description

Technical Field

[0001] This invention relates to the field of laser measurement technology, specifically to a laser measurement device for connector testing. Background Technology

[0002] Laser measuring devices for connector inspection are specialized tools for high-precision testing of electronic connectors. They emit a high-precision laser beam to measure the dimensions, position, and geometric features of various connector components. Equipped with a high-resolution optical system, the device focuses the laser beam onto the connector and acquires measurement data using reflected or scattered light. A detector precisely captures the reflected light signal, calculating the connector's actual dimensions and shape to ensure compliance with design specifications and quality standards. This type of device is widely used in electronics manufacturing and quality control to ensure the high precision and reliability of connectors.

This invention's laser measuring device, knowing the distance L from the rotation axis of a precision part to the laser rangefinder, and measuring the distance D between the laser rangefinder and the precision part, establishes a coordinate system with the distance moved by the lifting drive mechanism as the vertical axis and the value of L as the horizontal axis, obtaining a two-dimensional point cloud map of the sidewall profile of the precision part facing the laser rangefinder.

After testing, motor B is activated, causing the upper clamping assembly to release the tested connector. Simultaneously, the lower clamping assembly moves towards the center to clamp the connector to be tested below. Then, motor A is activated, driving the fixing stage to rotate. One end of the fixing stage contacts a rubber protrusion and a telescopic pressure plate, causing the sleeve D and movable rod B to rotate. Under the connection of the fixing frame, fixing ring, and metal strip, the movable rod A rotates, causing the insertion plate to rotate upwards. This allows the insertion plate inserted into the bottom groove A to lift from the bottom of the tested connector. The connecting stage, in conjunction with the pushing short plate, pushes the connector on one side, ensuring stable unloading of the tested connector. Simultaneously, the connector to be tested is moved upwards by the rotation, waiting for the fixing stage to move horizontally before being tested again. This achieves rapid unloading of tested connectors and loading of untested connectors, improving testing efficiency. Attached Figure Description

Then, motor A341 is turned on to drive the fixed platform 35 to rotate. When the fixed platform 35 rotates, one end of the fixed platform 35 contacts the rubber protrusion 471 and the telescopic pressure plate 47, causing sleeve D45 and movable rod B44 to rotate. Through the connection action of fixed frame 451, fixed ring 452, and metal strip 46, The rotating rod A41 rotates, causing the insertion plate 43 to rotate upwards. After the insertion plate 43 is inserted into the bottom groove A351, it rotates and lifts the inspected connector from the bottom. The connecting table 353, together with the pushing plate 354, pushes the connector on one side to ensure that the inspected connector is stably unloaded. The connector to be inspected is sent to the top under the action of rotation and waits for the fixed table 35 to move horizontally for inspection. The telescopic pressure plate 47 is telescopic to ensure that the tilt angle of rotation during connection is sufficient for the connector to slide down.

When the connector is transported upward by the lifting platform 5, the partition plate 111 separates the connectors. At the same time, the infrared detector 6 is used to detect whether there is a connector to be tested. Each time the lower clamping assembly 368 removes the connector to be tested, if the infrared detector 6 detects that there is no object at the current position, the lower connector is transported upward by the lifting platform 5.

[0041] A side frame 2 is fixedly connected to the upper surface of the testing table 1. A connecting horizontal plate 21 is fixedly connected to the inner wall of the side frame 2.

[0042] A controller B is located on the outer side of side frame 2. The controller includes a laser emitting module for controlling the laser switch.

The image processing module is connected to a data processing module for evaluating connector dimensional compliance and surface defects. The data processing module is connected to an automatic control module for highlighting abnormal data areas. The automatic control module is connected to a user operation module for setting parameters, viewing test results, and accessing the system control interface. The laser is emitted by the laser emitting module, received by the optical receiving module, and the image processing module converts the received signal into... Figure 9 The system uses a two-dimensional coordinate graph, a data processing module to determine the difference between the detected image and the standard image, an automatic control module to mark abnormal areas with different color blocks, and finally a user operation module to feed back the detection results to the operator to complete the detection operation.

[0043] Specifically, when fixing the connector, motor B355 is turned on. Motor B355 drives the rotating rod A361 and the driving gear 362 to rotate. The driving gear 362 drives one set of movable gears 366 and driven gear 364 to rotate. The driven gear 364 drives the other set of movable gears 366 to rotate. Through the counter-rotation of the two sets of movable gears 366, the upper clamping assembly 367 is driven to clamp towards the center to fix the connector, while the lower clamping assembly 368 moves to both sides to open, thereby fixing the upper connector. Then, motor 31 is turned on, driving the rotating shaft 32 and lead screw 33 to rotate. The connecting shell 34 moves along the direction of lead screw 33, causing the connector to move and complete the testing. After the connector testing is completed, motor B355 is turned on, rotating the drive gear 362, driven gear 364, and movable gear 366. This causes the upper clamping assembly 367 to release the tested connector, and the lower clamping assembly 368 to move towards the center, clamping the connector to be tested below. Then, motor A341 is turned on, driving the fixed stage 35 to rotate. During rotation, one end of the fixed platform 35 contacts the rubber protrusion 471 and the telescopic pressure plate 47, driving the sleeve D45 and the movable rod B44 to rotate. Through the connection of the fixed frame 451, the fixed ring 452 and the metal strip 46, the movable rod A41 is driven to rotate, causing the insertion plate 43 to rotate upward. The insertion plate 43 inserted into the bottom groove A351 rotates, lifting the inspected connector from the bottom. The connecting platform 353, together with the pushing short plate 354, pushes on one side of the connector to ensure the stable feeding of the inspected connector. At the same time, the connector to be inspected is sent to the top under the action of rotation, waiting for the fixed platform 35 to move horizontally for inspection. The infrared detector 6 in the loading port 11 is used to detect whether there is a connector to be inspected. Each time the clamping assembly 368 takes away the connector to be inspected, the infrared detector 6 detects that there is no object at the current position, and then the lifting platform 5 transports the connector below upward to replenish the connector. After that, the fixed platform 35 moves back and forth and rotates to quickly feed the inspected connector and feed the uninspected connector, thereby improving the inspection efficiency.
