Abstract
Description
Technical Field
[0001] This utility model relates to the field of encoder technology, specifically to an encoder optical detection component. Background Technology
[0002] An encoder is a sensor device that converts physical signals (such as rotation angle, linear displacement, etc.) into electrical signals (such as pulses, codes, etc.). It is widely used in robotics, CNC machine tools, and motor control. An encoder is basically composed of mechanical parts, light-emitting and receiving parts, and circuit parts. The mechanical parts consist of components such as the spindle, body, and bearings, while the light-emitting and receiving parts consist of light-emitting, receiving, and grating components.
[0003] When the encoder is working, the spindle and other components can easily generate heat inside the housing. If the heat accumulates inside the housing and is not dissipated in time, it can easily cause the components to overheat, leading to performance degradation or malfunction, and affecting the normal operation of the encoder.

[0021] 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.
[0022] This utility model provides a technical solution: such as Figures 1 to 5 As shown, in this embodiment, an encoder optical detection component includes an encoder housing 1. The encoder housing 1 has multiple heat dissipation grooves 2 evenly distributed circumferentially inside. The encoder housing 1 has multiple slots 3 evenly distributed circumferentially on its surface. The number and position of the slots 3 correspond to those of the heat dissipation grooves 2. A heat-conducting plate 4 is embedded inside the slot 3. The heat-conducting plate 4 is made of copper. A heat dissipation fin 5 is fixedly connected to the side of the heat-conducting plate 4 away from the slot 3. Four plug-in blocks 6 are evenly distributed circumferentially on one side of the heat dissipation fin 5. A fixing screw 7 is provided inside the plug-in block 6.
[0023] The encoder housing 1 has four locating grooves 8 evenly distributed around its surface. The locating grooves 8 are compatible with the plug-in block 6. The locating grooves 8 have threaded grooves 9 inside, and the fixing screws 7 are threaded into the threaded grooves 9.
[0024] Align the positions of the plug block 6 and the positioning groove 8, slide the heat-conducting plate 4 inside the slot 3, and move the plug block 6 completely into the positioning groove 8. Then, use the fixing screw 7 to fix the plug block 6 to the encoder housing 1, thereby completing the installation of the heat dissipation fins 5. When the encoder is in use, the heat generated by the internal components moves along the heat dissipation groove 2. Since the heat-conducting plate 4 corresponds to the heat dissipation groove 2 and the heat-conducting plate 4 is made of copper, the heat accumulated near the heat dissipation groove 2 can be conducted out and dissipated to the outside through the heat dissipation fins 5, thereby achieving heat dissipation of the encoder to ensure its normal operation.
[0025] The encoder housing 1 has four positioning grooves 10 at the end away from the heat sink 5, and the positioning grooves 10 have through holes 11 inside.
[0026] An end cap 12 is provided at the end of the encoder housing 1 away from the heat sink fin 5. A positioning plate 13 is fixedly connected to the side of the end cap 12 near the encoder housing 1. Four protrusions are provided on the surface of the positioning plate 13. The protrusions are fitted into the inside of the positioning groove 10. Four fixing screws 14 are provided on the surface of the encoder housing 1. The fixing screws 14 pass through the through hole 11 and are threadedly connected to the protrusions.
[0027] Insert the positioning plate 13 into the encoder housing 1. At this time, the protrusion on the positioning plate 13 moves into the positioning groove 10 and realizes the quick correspondence between the through hole 11 and the screw groove on the end cover 12. Insert the fixing screw 14 into the through hole 11 and rotate the fixing screw 14 to fix the end cover 12 and the encoder housing 1, thereby improving the ease of installation.
[0028] The end cover 12 is rotatably connected to a main shaft 15, and a bearing 16 is provided between the main shaft 15 and the end cover 12.
[0029] The end cap 12 has two symmetrical threaded grooves 17 on the side opposite to the positioning plate 13. A connecting plate 18 is provided on the side of the end cap 12 opposite to the positioning plate 13. A fixing screw 20 is threadedly connected between the connecting plate 18 and the threaded groove 17. An arc groove 19 is provided inside the connecting plate 18.
[0030] The encoder housing 1 has a connecting line 21 inside. A fixing sleeve 22 is fixedly connected to the side of the encoder housing 1 away from the end cover 12. A rubber pad 23 is provided inside the fixing sleeve 22. The rubber pad 23 and the fixing sleeve 22 are located outside the connecting line 21.
[0031] The fixing sleeve 22 is fitted onto the surface of the connecting wire 21, and the fixing sleeve 22 is installed on the encoder housing 1 using screws. Thus, when the encoder is in use, the fixing sleeve 22 fixes the connection between the connecting wire 21 and the encoder housing 1, preventing friction between the connecting wire 21 and the encoder housing 1 that could cause wear to the connecting wire 21. In addition, a rubber pad 23 is provided inside the fixing sleeve 22. The connecting wire 21 and the fixing sleeve 22 compress the rubber pad 23, thereby ensuring the sealing of the connection.
[0032] This utility model provides an encoder optical detection component, the specific working principle of which is as follows:
[0033] In use, the positioning plate 13 is inserted into the encoder housing 1. At this time, the protrusion on the positioning plate 13 corresponds to the positioning groove 10. The fixing screw 14 is inserted into the through hole 11 and rotated to fix the position of the end cover 12 and the encoder housing 1. The position of the plug block 6 corresponds to the positioning groove 8. The heat conduction plate 4 slides inside the slot 3. The plug block 6 is completely moved into the positioning groove 8 and fixed to the encoder housing 1 with the fixing screw 7. This completes the installation of the heat dissipation fins 5. When the encoder is working, the heat generated by the component is discharged through the heat dissipation groove 2 and the heat conduction plate 4, and the heat is dissipated to the outside through the heat dissipation fins 5, thereby realizing the heat dissipation of the encoder and ensuring its normal operation.
