Abstract
Description
Technical Field
[0001] This invention belongs to the field of automatic clamping technology, and in particular relates to a fast and high-precision automatic clamping device and method for optoelectronic products. Background Technology
[0002] As a key component at the projectile's tip, a certain type of optoelectronic product's core function is to receive the laser echo signal scattered by the target. This, combined with an internal position calibration system (including a gyroscope and optical receiver) and electronic components, enables target tracking and ultimately guides the projectile to accurately attack the target. To verify the product's performance, two types of tests are required: static and dynamic. In static testing, the product's gyroscope is locked and does not rotate; the testing equipment moves the product at a set angle. In dynamic testing, the gyroscope is unlocked, and the internal spring steel band is released instantaneously, causing the gyroscope to rotate at high speed. Simultaneously, the testing equipment must move at high speed to simulate the product's actual working scenario. Both types of tests require a stable and reliable connection between the product and the testing equipment; otherwise, test data deviations will occur, making it impossible to accurately determine product performance. Therefore, a dedicated clamping device is urgently needed to ensure effective connection between the product and the testing equipment.
[0003] However, existing testing scenarios face multiple technical limitations, posing challenges to the design of clamping devices: on the one hand, the mechanical structure of the testing equipment has been fixed for a long time, the space available for clamping is very limited, and there are strict requirements for the energy of the product's light source, which cannot be affected by the clamping structure blocking or interfering with the energy. On the other hand, the high-speed rotation of the product's gyroscope in dynamic testing will generate vibration, and the relative displacement between the two must be avoided when the equipment moves the product. This places high demands on the stability, buffering and adaptability of the clamping device. Existing clamping devices cannot simultaneously meet the testing requirements of small space adaptation, no light source interference, and stable connection between dual testing modes. Summary of the Invention
[0004] The purpose of this invention is to address the above-mentioned problems by providing a fast and high-precision automatic clamping device and method for optoelectronic products.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fast and high-precision automatic clamping device for optoelectronic products, comprising a transition component and a fixing component, wherein one end of the transition component is used to install the optoelectronic product, and the other end of the transition component is assembled and docked with the fixing component, and the transition component is installed at the test end of the test equipment through the fixing component; The transition assembly includes a fixed sleeve, an inner sleeve, a fixed rod, and a connecting block. The inner sleeve is coaxially disposed inside the fixed sleeve and is fixedly connected to the fixed sleeve by screws. The connecting block is fixed to the outer wall of the fixed sleeve, and the fixed rod is slidably connected to the connecting block and the side wall of the fixed sleeve. The fixing assembly includes a connecting ring, a first fastening block, a second fastening block, and a guide block. The first fastening block is fixed to the outer ring wall of the connecting ring, the guide block is fixed to the outside of the first fastening block, and the second fastening block is fixed to the side wall of the first fastening block away from the connecting ring.
[0006] Preferably, the transition assembly further includes a flexible connector, which is arranged axially along the fixed rod and fixed to the side wall of the fixed sleeve. The flexible connector is slidably connected to the end of the fixed rod near the fixed sleeve, and the fixed rod moves telescopically through the flexible connector.
[0007] Preferably, the sidewall of the fixing sleeve is provided with multiple hollow holes, and the hollow holes are evenly distributed along the annular sidewall of the fixing sleeve.

[0011] Preferably, the inner wall of the connecting ring is provided with an internal thread groove, and the connecting ring is connected to the test end of the test equipment through the internal thread groove.
[0012] A rapid and high-precision automatic clamping method for optoelectronic products, which utilizes the aforementioned rapid and high-precision automatic clamping device for optoelectronic products, includes the following steps: Step 1: The product is removed from the lineside warehouse. The composite AGV transports the product to the roller line of the product testing equipment. The robot starts and takes pictures of the installation position of the testing equipment and the position of the product in the bin. Step 2: Send the product photo information to the product transfer equipment, and the transfer equipment will rotate to make way; Step 3: The robot uses its gripping tool to pick up the product from the bin and install it into the transition component at the product transfer equipment, then rotates back to the initial position. Step 4: The robot changes its gripper, picks up the transition component with the product installed from the transfer device, and connects the transition component to the fixed component at the testing device; Step 5: The robot moves to a safe position and completes product clamping; Step 6: Start the testing equipment and test.

Detailed Implementation
[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0019] like Figures 1-8 As shown, a fast and high-precision automatic clamping device for optoelectronic products includes a transition component 1 and a fixing component 2. One end of the transition component 1 is used to install the optoelectronic product, and the other end of the transition component 1 is assembled and docked with the fixing component 2. The transition component 1 is installed at the test end of the test equipment through the fixing component 2.
[0020] The transition component 1 includes a fixed sleeve 101, an inner sleeve 102, a fixed rod 103, and a connecting block 104. The inner sleeve 102 is coaxially disposed inside the fixed sleeve 101 and is fixedly connected to the fixed sleeve 101 by screws. The connecting block 104 is fixed to the outer wall of the fixed sleeve 101, and the fixed rod 103 is slidably connected to the connecting block 104 and the side wall of the fixed sleeve 101. The end face of the inner sleeve 102 is provided with a plurality of annularly distributed spring holes 105, and a support spring 106 is provided inside the spring holes 105. Among them, the diameter of the end of the fixing rod 103 away from the fixing sleeve 101 is 18 mm. During the automatic product clamping process, the robot's clamping device needs to have a certain force to dock the product. The robot needs clamping tools during the clamping process. After the product is assembled, the clamping tools make contact with the surface with a diameter of 18 mm to ensure that the product is reliably fixed when it is not clamped. The inner ring diameter of the fixing sleeve 101 is 146 mm. The side wall of the fixing sleeve 101 is provided with multiple hollow holes 3, and the hollow holes 3 are evenly distributed along the annular side wall of the fixing sleeve 101. This can reduce the weight of the product clamping device and ensure that the product speed meets the technical specifications during product testing. The transition component 1 also includes a flexible connector 107 (the flexible connector 107 is a spring). The flexible connector 107 is arranged axially along the fixed rod 103 and fixed to the side wall of the fixed sleeve 101. The flexible connector 107 is slidably connected to the end of the fixed rod 103 near the fixed sleeve 101. The fixed rod 103 moves telescopically through the flexible connector 107, which facilitates the telescopic movement of the fixed rod 103, makes it easier to fix the product, and facilitates the snap-fit fixation of the transition component 1 and the fixed component 2.
[0021] The fixing component 2 includes a connecting ring 201, a first fastening block 202, a second fastening block 203, and a guide block 204. The first fastening block 202 is fixed to the outer ring wall of the connecting ring 201. The guide block 204 is fixed to the outside of the first fastening block 202. The second fastening block 203 is fixed to the side wall of the first fastening block 202 away from the connecting ring 201. The first fastening block 202 is provided with a mating hole 4, which is coaxial with the fixing rod 103. The rod wall of the fixing rod 103 is sleeved with a positioning post 5. The outer diameter of the positioning post 5 is adapted to the diameter of the mating hole 4. After the transition component 1 and the fixing component 2 are mated, the positioning post 5 can be engaged with the mating hole 4 to ensure a stable connection between the transition component 1 and the fixing component 2. The connecting ring 201 has a maximum end diameter of 150 mm and an inner ring diameter of 146 mm. The inner ring is designed with 6 threaded holes for installing hexagon socket head cap screws. Two of the holes have a diameter of 4.2 mm and are completely through the screws. The inner surface M5-6H is completely through both ends. The distance between the two holes is 24 mm. The device width is 16 mm, which can reliably connect to product testing equipment. The first buckle 202 has a hole with a diameter of 10 mm. This size can meet the product's own weight and speed requirements during high-speed rotation to achieve the product testing technical specifications, ensure the stability of product rotation, and prevent the product clamping device from slipping off the track. The second fastener 203 is 36 mm long and 14.5 mm wide, containing three through holes. Two symmetrical through holes with a diameter of 5.5 mm are completely through, with a distance of 24 mm between them. The middle hole has a diameter of 10 mm, with an upper tolerance of +0.05 mm and a lower tolerance of +0.03 mm. It is in a through state. At the bottom, there is a threaded hole with a diameter of 2.5 mm and a depth of 8.5 mm. Its nominal diameter is 3 mm, the thread machining grade is 6, the basic deviation of the thread is H, and the thread depth is 6 mm. The guide block 204 is provided with two guide parts 6, which are respectively located on both sides of the first buckle block 202. The sidewalls of the two guide parts 6 facing each other are provided with inclined guide ramps. During the docking process between the transition component 1 and the fixing component 2, the guide ramps of the guide parts 6 can correct the deviation of the transition component 1 and ensure accurate docking. The angle of the guide ramp is 15°, the distance between the two guide parts 6 is 36 mm, the upper tolerance is +0.05 mm, the lower tolerance is 0.02 mm, the height is 20 mm, and the chamfer size is 10 mm. The sidewalls of the guide block 204 are provided with three holes with a diameter of 5 mm to facilitate the connection and fixation with the first buckle block 202. The inner wall of the connecting ring 201 is provided with an internal thread groove 7, and the connecting ring 201 is connected to the test end of the test equipment through the internal thread groove 7, which facilitates the connection between the connecting ring 201 and the test end of the test equipment.
[0022] The operating principle of the present invention is explained as follows: The product is removed from the lineside warehouse, and the composite AGV transports the product to the roller line of the product testing equipment. The robot starts, takes pictures of the installation position of the testing equipment, takes pictures of the position of the product in the bin, and then transmits the product photo information to the product transfer equipment. The transfer equipment rotates to make way. The robot then uses a gripping tool to pick up the product from the hopper and install it into the transition component 1 at the product transfer equipment (the lower outer wall of the product has a ring-shaped protrusion with a width of about 10mm, which ensures stable contact between the product and the transition component 1). It then rotates back to its initial position. Next, the robot changes its gripper and picks up the transition component 1 with the product installed from the transfer equipment, bringing it close to the fixed component 2 at the testing equipment. The transition component 1 and fixed component 2 are coaxial; this position is the approach point. The robot then controls the transition component 1 to approach the fixed component 2 at a speed of 0.01m / s. The internal support spring 106 of component 1 is compressed by the compressive force, and the distance between the transition component 1 and the fixed component 2 is maintained at 1 mm to 2 mm. This is the alignment point. Then, the transition component 1 is controlled to continue moving at a speed of 0.01 m / s. During the guidance process, if the transition component deviates slightly, the position of the transition component can be corrected by the guide ramps at the two guide parts of the guide block, ensuring the precise docking of the transition component and the fixed component. When the fixed rod 103 moves to the position of the first buckle block, under the action of the flexible connector 107, the fixed rod pops out from the docking hole 4 of the first buckle block 202, completing the connection between the transition component 1 and the fixed component 2. The robot then moves to a safe position, completes the product clamping, starts the testing equipment, and performs product testing. After the test is completed, a signal is sent to the robot, which then moves to disassemble the product according to the reverse process of clamping. The disassembled transition component 1 is placed on the product testing transfer equipment. The robot then changes its gripping tool, picks up the product, and places it in the product material box according to the system-set position. The robot then moves to a safe point. The above tests are divided into static product tests and dynamic tests: During static testing of a product, the product itself is a rigid body with all components fixed together. This mainly refers to the product position calibration system, where all components are in a coaxial state. The rotation and angle of the product are achieved primarily through the rotation and angular offset of the product testing equipment. The robot does not move. During dynamic testing of the product, the product itself is no longer a rigid body, but is in a flexible connection state. This mainly refers to the product position calibration system. The components are no longer in a coaxial state, and the optical system can rotate freely, meaning the product is in an unlocked state. At this time, the product can receive a fixed laser code, thereby achieving target capture and tracking. After the robot clamps the product into place, it is necessary to change the unlocking tool and strike a fixed button on the product testing equipment to unlock the product gyroscope.
[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
