Description

Technical Field

[0001] This utility model relates to a laser projector illuminance testing device, belonging to the technical field of illuminance testing equipment. Background Technology

[0002] Laser projectors require illuminance testing during production to ensure product quality. Previously, the most common method was to manually point the laser projector at an illuminance meter in a darkroom, connect the power supply and heat sink manually, and then manually move the product to the testing position of the illuminance meter for testing.

[0003] This type of method relies entirely on manual operation, resulting in low efficiency. Furthermore, the manual connection of power and installation of heat sinks before and after testing leads to intermittent stops during continuous testing, disrupting the seamless integration of testing with subsequent processes. Additionally, manually moving the laser projector makes it impossible to accurately capture true illuminance; it also requires a large workforce. Therefore, a laser projector illuminance testing device is needed to address the problems of low efficiency, poor accuracy, and high workload associated with manual laser projector illuminance testing in existing technologies.

The lux meter moving assembly includes a moving frame 31, a guide rail 3, a moving motor 30, a radial motor 1, a mounting frame 32, and a projection screen 7.

One end of the connecting plate extends to the front side of the projection screen to form a mounting end. The lux meter 4 is fixedly installed on the mounting end. In addition, to ensure that the illuminance meter can slide accurately to the test station, position sensing blocks are respectively provided on the guide rail corresponding to the two test units in this embodiment, and position sensors are installed on the mounting bracket, with the position sensing blocks located within the movement trajectory of the position sensors.

[0031] The fasteners in this embodiment include positioning pins 18 and clamps 15. The mounting base is provided with a mounting groove that matches the shape of the laser projector. The laser projector is provided with four positioning holes. Four positioning pins are installed in the mounting groove of the mounting base. A shim block 14 is installed on the mounting base located outside the mounting groove. A clamp 15 is fixedly installed on the shim block. When the laser projector is installed on the mounting base, the positioning pins correspond one-to-one with the positioning holes, and the laser projector is fixed by the clamps. In addition, the number of heat sinks in this embodiment is two, and the heat sinks are installed in the test unit one-to-one. The heat sinks include an upper heat sink 22 and a lower heat sink 17. The lower heat sink is installed in the cavity formed between the base plate and the column, and its heat dissipation surface penetrates the upper plate to form a heat dissipation end. When the laser projector is installed on the mounting base, the heat dissipation end of the lower heat sink is in contact with the laser projector. The upper heat sink 17 is installed on the frame at the test station through a pressing assembly. The pressing assembly includes a fixed frame, a pressing cylinder 21 and a fixed plate. The fixed frame includes a fixed vertical plate 19 and a fixed horizontal plate 20. The fixed vertical plate is fixedly installed on the frame, and the fixed horizontal plate is fixedly installed on the top of the fixed vertical plate. The pressing cylinder is fixedly installed on the fixed horizontal plate, and its power end is connected to the fixed plate. The upper heat sink is fixedly installed on the fixed plate.

[0032] The laser projector illuminance testing equipment of this embodiment is equipped with a control component, which includes a controller and two barcode scanners. The controller has a data storage module, and the illuminance meter and the barcode scanners are electrically connected to the controller. The two barcode scanners are installed one-to-one on the rack on the side of the testing unit. Each barcode scanner includes a bracket and a barcode scanner 23. The bracket is installed on the rack on the side of the loading station, and the barcode scanner is fixedly installed on the top of the bracket. The scanning head of the barcode scanner faces the loading station controller and is equipped with a data transmission module, which is equipped with a wireless or / and wired transmission interface.

[0033] Working Principle: In this embodiment of the laser projector illuminance testing equipment, the tester simply needs to manually place the laser projector onto the mounting base. During placement, the positioning holes of the laser projector align with the positioning pins on the mounting base to ensure accurate installation. The power connection terminal of the laser projector automatically engages with the power probe to supply power. The heat dissipation end of the lower heat sink on the upper plate is then attached to the laser projector. The tester then manually operates the clamps to secure the laser projector to the mounting base, completing the product installation process.

[0034] Next, the tester starts the testing equipment. The controller controls the synchronous motor, which drives the synchronous belt to slide the mounting base of the test unit with the product installed towards the testing station. Simultaneously, it drives the mounting base of the test unit without the product installed towards the loading station. At the same time, the controller starts the moving motor, driving the mounting frame to slide to the testing station with the product-installed mounting base, so that the illuminance meter can perform illuminance testing on the laser projector. The tester then installs the product into the mounting base of the test unit without the product installed. After the test is completed, the synchronous motor resets the synchronous belt, allowing the mounting bases of the two test units to alternate positions. The tester removes the tested product and then assembles a new product, repeating the above steps to continuously perform illuminance testing on the products.

[0035] It is important to note that each time the tester completes product installation, the barcode scanner automatically scans the serial number (SN) of the installed laser projector to identify the information of the object under test. After the test is completed, the controller automatically records the test data based on the feedback data from the illuminance meter, binds the data with the information of the object under test, and then automatically stores it. After completing all tests, the tester can retrieve the data via wired or wireless means for data analysis.

[0036] The embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. For those skilled in the art, after learning the contents of the present invention, several equivalent changes and substitutions can be made without departing from the principle of the present invention. These equivalent changes and substitutions should also be considered to fall within the protection scope of the present invention.
