Description

Technical Field

[0001] The present invention is applied to the technical field of testing equipment, and particularly relates to a fully automatic light spot testing machine. Background Art

[0002] With the rapid development and application of new optical components, the demand for optical component testing tools and equipment has also increased significantly. With the increasing requirements for the performance of light-emitting components, the importance of light beam analysis, light intensity, and beam size testing has become increasingly important. The light intensity and beam size of a light source can be measured based on a hotspot image of the light source's spot. Existing spot hotspot testing equipment has a complex structure and a low level of automation. It is generally suitable for manual or semi-automatic testing and cannot meet the conditions for large-scale testing, resulting in low test efficiency.

[0003] For spot testing of light-emitting components, a test fixture is typically used to secure the product under test and a camera in place. The product is then powered on and illuminated, and the camera captures the light spot emitted by the product. The captured light spot is then analyzed to derive the relevant optical parameters of the product under test. Different test items have different requirements for the distance between the light source and the camera, as well as the angle of incidence. Therefore, ensuring the relevant accuracy is key to ideal testing. Currently, most methods employ mechanical clamping to secure the light source and camera for testing. The adjustability and accuracy of these mechanisms are relatively low. Even if an adjustable structure is implemented, there is a lack of appropriate detection methods to ensure the required accuracy, making it difficult to achieve a relatively ideal testing environment. For example, Chinese Patent Publication No. 207300547U discloses a fully automatic spot hotspot testing machine. However, its camera position cannot be adjusted, making it unable to meet the testing requirements of existing optical products. Furthermore, it cannot meet the power-on requirements of small products.

[0004] In addition, the product to be tested is relatively small and can only be powered by a dedicated power supply board. It is not easy to power it using conventional methods. The traditional power-on method is to connect the probe assembly to the power supply, set the product on a fixed fixture, and control the power supply by turning the power on and off. However, this method cannot be applied to the power supply of products clamped on a movable carrier. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a fully automatic spot testing machine that can adjust the state of the camera module, has high precision and work efficiency, and can power on small-sized products.

[0006] The technical solution adopted by the present invention is: the present invention includes a machine base, a lifting mechanism, a rotating carrier module, a camera module and a carrier, the machine base is provided with a support frame, the support frame is provided with a limit opening, the rotating carrier module is provided with a placement groove that cooperates with the carrier, the lifting mechanism is used to lift the carrier and connect the power supply so that the carrier is limitedly matched with the limit opening, the camera module includes an angle adjustment block, a three-axis adjustment assembly and an industrial camera, the angle adjustment block is fixed on the support frame, the industrial camera is connected to the inclined surface of the angle adjustment block through the three-axis adjustment assembly, and the industrial camera is located above the limit opening.

[0007] As can be seen from the above scheme, the machine base provides overall support, and the rotating carrier module is used to drive the carrier to switch between the test station and the loading and unloading station. The carrier is driven to rise from the rotating carrier module by the lifting mechanism, so that the carrier cooperates with the limit port to keep the light spot position fixed, thereby ensuring the position accuracy of the product components and improving the detection accuracy. At the same time, by setting different angle adjustment blocks for connection, the angle adjustment of the industrial camera is achieved, and the verticality of the camera and the incident light of the product is changed. The position of the industrial camera is adjusted by the three-axis adjustment assembly, and then the position of the industrial camera relative to the light spot is adjusted. The product is clamped by a separate carrier, which facilitates the transportation of the product between different equipment and improves automation.

[0008] A preferred solution is that the support frame is provided with a cover plate that cooperates with the limiting opening, and the cover plate is provided with a light hole that cooperates with the carrier.

[0009] As can be seen from the above solution, by setting the cover plate to limit the upper end surface of the carrier, the state of the carrier in the test position is further restricted, thereby improving the detection accuracy. The light hole is used for projecting light spots on the product.

[0010] A preferred solution is that the three-axis adjustment assembly includes a first micrometer fine-tuning platform, a second micrometer fine-tuning platform, a fixed frame and a high-precision slide, the first micrometer fine-tuning platform is fixed on the inclined surface of the angle adjustment block, the second micrometer fine-tuning platform is fixed on the movable end of the first micrometer fine-tuning platform, the fixed frame is fixed on the movable end of the second micrometer fine-tuning platform, the high-precision slide is fixed on the fixed frame, the industrial camera is fixed on the movable end of the high-precision slide, and the movement direction of the first micrometer fine-tuning platform, the movement direction of the second micrometer fine-tuning platform and the movement direction of the high-precision slide are perpendicular to each other.

[0011] It can be seen from the above scheme that a high-precision three-axis adjustment mechanism is formed by setting two micrometer fine-tuning platforms and high-precision slides perpendicular to each other, which can accurately and reliably adjust the position of the industrial camera. At the same time, the adjustment data can be easily obtained through the micrometer, which is convenient for recording the spot data.

[0012] A preferred solution is that the carrier includes a base, a flip cover, a conductive plate, a soft cable and a guide needle assembly, the flip cover is hingedly fitted on the base, the guide needle assembly includes a movable block slidingly fitted on the base and a guide needle block arranged on the movable block, the conductive plate is electrically connected to the guide needle block through the soft cable, the base is provided with a product limit block that cooperates with the guide needle block, the flip cover is provided with a pressing block that cooperates with the product limit block, and the conductive plate cooperates with the power supply structure on the lifting mechanism.

[0013] As can be seen from the above scheme, the connection between the conduction plate and the guide needle block is achieved through a flexible flat cable, ensuring that small products can be powered on and off, while the guide needle block can also be turned on and off. The conduction plate is generally used to connect to the power supply structure to achieve power transmission. By adopting a design in which the movable block is slidably arranged on the base, the guide needle block can move closer to or further away from the product's power supply board, achieving power-on and power-off control, and the movable block is controlled by an external drive structure. The flip cover is used to press the product.

[0014] A further preferred solution is that the lifting mechanism includes a lifting cylinder, a lifting seat, a guide plate, a power connector and a vacuum suction cup, the vacuum suction cup and the power connector are both fixed on the guide plate, the guide plate is connected to the lifting seat through a first floating structure, the lifting cylinder is fixed on the machine base, the lifting seat is fixed on the movable end of the lifting cylinder, the vacuum suction cup is connected to an external vacuum generator, the power connector is connected to an external power supply, and the power connector is adapted to the conduction plate.

[0015] As can be seen from the above solution, the floating connection reduces the impact force between the carrier and the guide plate during docking, thereby reducing the impact of the impact on the product. The vacuum suction cup is used to firmly hold the carrier, ensuring that it does not deviate significantly during lifting. The power connector is used to dock with the conductive plate to achieve power transmission. The guide plate is used to support the carrier.

[0016] A further preferred solution is that a plurality of guide posts are provided on the guide plate, and a plurality of guide sleeves corresponding one-to-one with the plurality of guide posts are provided on the bottom surface of the base.

[0017] It can be seen from the above solution that by providing the guide column and the guide sleeve, the carrier is prevented from being offset during the process of the lifting mechanism lifting the carrier, the movement accuracy of the carrier is improved, and the final product is ensured to accurately reach the test position.

[0018] A further preferred solution is that an electric mechanism is provided on the support frame, and the electric mechanism includes an upper electric cylinder and a push block. The upper electric cylinder is fixed on one side of the limit opening, and the push block is fixedly connected to the movable end of the upper electric cylinder. The push block slides and fits on the support, and a slide groove adapted to the push block is provided on one side of the limit opening, and the end of the push block away from the upper electric cylinder cooperates with the movable block.

[0019] It can be seen from the above solution that the movable block is pushed by the power-on mechanism so that the movable block is close to the product, thereby causing the guide needle block to dock with the power supply board of the product.

[0020] A further preferred solution is that the guide needle block is connected to the movable block via a second floating structure.

[0021] As can be seen from the above solution, the second floating structure is provided to absorb the impact when the guide needle block is docked with the product power supply board, thereby protecting the product and the micro probe on the guide needle block.

[0022] A preferred solution is that the rotating carrier module includes a rotating cylinder and a movable plate, the rotating cylinder is fixed on the machine base, the center of the movable plate is fixedly connected to the movable end of the rotating cylinder, both ends of the movable plate are provided with the placement groove, the placement groove is square, and the four corners of the placement groove are provided with support blocks that cooperate with the carrier.

[0023] As can be seen from the above scheme, by providing two placement slots at the same time, the loading and unloading operations of the carrier can be carried out simultaneously with the detection, thereby improving production efficiency. By providing four support blocks to support the carrier, it is ensured that the lifting mechanism can lift the carrier while the carrier can be stably placed in the placement slot.

[0038] In this embodiment, the support frame 6 is provided with an electrification mechanism, which includes an upper electric cylinder 604 and a push block 605. The upper electric cylinder 604 is fixed to one side of the limiting opening 601, and the push block 605 is fixedly connected to the movable end of the upper electric cylinder 604.

[0040] In this embodiment, the rotating carrier module 3 includes a rotating cylinder 302 and a movable plate 303. The rotating cylinder 302 is fixed on the machine base 1.

[0041] Working principle of the present invention:

[0042] The angle adjustment block 401 is installed at a corresponding angle according to the test requirements. In this embodiment, the angle of the angle adjustment block 401 is 45 degrees. The position of the industrial camera 402 is adjusted by the three-axis adjustment assembly.

[0043] The product is placed on the product limiting block 507 , and the flip cover 502 is fastened so that the pressing block 508 cooperates with the product limiting block 507 to clamp the product.

[0044] The carrier 5 is placed on the placement slot 301 by an external transport device, and the rotating cylinder 302 is activated to drive the movable plate 303 to rotate 180 degrees, so that the current carrier 5 moves to the top of the lifting mechanism 2.

[0046] After the product is powered on, it emits light, and the industrial camera 402 takes a picture of the projected light spot for detection, which is then analyzed by the host computer.
