Description

Technical Field

[0001] This utility model relates to the field of optocoupler technology, and in particular to an optocoupler alignment device. Background Technology

[0002] The English name for optocoupler is optical coupler, abbreviated as OC, also known as opto-isolator, or simply optical coupler. Optical coupler isolation uses an optical coupler for isolation. The structure of an optical coupler is equivalent to encapsulating a light-emitting diode (LED) and a phototransistor together. The LED converts the input electrical signal into an optical signal, which is then transmitted to the phototransistor for conversion into an electrical signal output. Because there is no direct electrical connection, this both couples and transmits the signal and isolates interference. When aligning the optocoupler, an optocoupler alignment device is required.

[0003] Current optocoupler alignment devices can basically meet people's needs, but some problems still exist, as detailed below:

[0004] 1. The problem of difficulty in adjusting the positioning position of the optocoupler alignment device: When aligning different optocouplers, it is necessary to adjust the position of different positioning plates so that the positioning plates can adapt to different situations.

[0005] 2. The optocoupler alignment device has difficulty in stably assembling and disassembling the laser chip. During use, the laser chip may fall off, and the fixation is not stable enough. Utility Model Content

[0006] The purpose of this invention is to provide a photoelectric coupling alignment device to solve the shortcomings of existing photoelectric coupling alignment devices, such as difficulty in adjusting the positioning position and difficulty in stably assembling and disassembling laser chips.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a photoelectric coupling alignment device, including a base plate;

[0008] A plate body is mounted on the top of the base plate, a positioning block is mounted on the top of the base plate, and a chip body is mounted on the top of the positioning block.

[0009] A laser chip is mounted on the top of the chip body, and a disassembly and assembly structure is mounted on both sides and both ends of the laser chip. A movable block is mounted on the top of the board body, and mounting plates are mounted on both sides of the movable block. A mounting screw passes through the middle of the mounting plate, and a positioning structure is mounted on the top of the movable block.

[0010] The positioning structure includes a fixed plate, a positioning plate, a scale, a threaded rod, and a guide rod, with the fixed plate installed at the top of the plate.

[0011] In use, the movable block can slide at the top of the plate. Moving the movable block adjusts the position of the fixed plate, which in turn adjusts the position of the positioning plate. The mounting plate and mounting screws form a threaded connection. Tightening the mounting screws fixes the movable block. The threaded rod and the fixed plate form a threaded connection. Tightening the threaded rod raises and lowers it, adjusting the height of the positioning plate to adapt to different situations and make alignment easier. The guide rod passes through the fixed plate to prevent it from shifting. The scale ensures stable and accurate positioning.

[0012] Furthermore, a heat dissipation structure is installed at the bottom of the plate, and the heat dissipation structure includes a connecting plate, a heat sink, and a heat dissipation groove. The connecting plate is installed at the bottom of the plate, and a heat sink is installed at the bottom of the connecting plate. The heat sink can dissipate heat quickly.

[0013] Furthermore, heat dissipation grooves are provided at both ends of the heat sink, and the heat sinks are arranged at equal intervals at the bottom of the connecting plate, thereby increasing the surface area of ​​the heat sinks.

[0014] Furthermore, a locking block is provided at the bottom of the laser chip, and a locking slot is provided at the top of the chip body. The laser chip and the chip body form a locking structure, which facilitates disassembly.

[0015] Furthermore, the disassembly and assembly structure includes a baffle, a rotating shaft, and a buckle. The baffle is installed on the top of the chip body, the rotating shaft is installed on the inner side of the baffle, and the buckle is installed on the top of the rotating shaft, which can fix the laser chip.

[0016] Furthermore, a threaded rod extends through the top of the fixing plate, and a positioning plate is installed at the bottom of the threaded rod. The bottom of the positioning plate is marked with a scale, and guide rods are installed on both sides of the top of the positioning plate. The lifting and lowering of the threaded rod can adjust the height of the positioning plate.

[0017] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the fixing plate is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the fixing plate are threadedly connected, and the rotation of the threaded rod can drive the positioning plate to rise and fall.

[0018] The advantages of the photoelectric coupling alignment device provided by this utility model are as follows: during use, the position of the positioning plate can be adjusted to make the positioning position easy to adjust when the photoelectric coupling is aligned. At the same time, the laser chip can be fixed by the buckle to prevent the laser chip from falling off.

[0019] A movable block is installed at the top of the plate, which can slide on the top of the plate. Moving the movable block can adjust the position of the fixed plate, and adjusting the position of the fixed plate can adjust the position of the positioning plate. The mounting plate and mounting screws form a threaded connection. Tightening the mounting screws can fix the movable block. The threaded rod and the fixed plate form a threaded connection. Tightening the threaded rod can drive the threaded rod to rise and fall. The rise and fall of the threaded rod can adjust the height of the positioning plate, allowing the positioning plate to adapt to different situations and making alignment easier. The guide rod passes through the fixed plate to prevent the fixed plate from shifting. The scale can make the positioning more stable and accurate, thereby achieving the purpose of the photoelectric coupling alignment device to facilitate the adjustment of the positioning position.

[0020] By installing a laser chip at the top of the chip body, the laser chip and the chip body form a locking structure. After the laser chip is inserted into the chip body, the rotating shaft on the inside of the baffle can rotate. The rotation of the rotating shaft can drive the buckle to rotate, and the buckle is locked on the top of the laser chip, which can fix the laser chip and prevent the laser chip from falling off during use. This achieves the purpose of the optocoupler alignment device to fix the laser chip. Attached Figure Description
