Detailed Implementation

[0027] 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.

[0028] Reference Figure 1-7 A heat dissipation structure and assembly / disassembly method for an optical module includes a main body unit 1. The main body unit 1 includes a base 4. A heat dissipation unit 2 is provided in the middle of the top of the base 4. Assembly / disassembly units 3 are provided on the top of the base 4 and on both sides of the heat dissipation unit 2. The heat dissipation unit 2 includes a heat dissipation frame 6 and a spring sheet 5. A plurality of heat-conducting plates 7 are provided on the top of the heat dissipation frame 6 and a heat-conducting plate 8 is provided on the bottom of the heat dissipation frame 6. The assembly / disassembly unit 3 includes two assembly / disassembly mechanisms. The two assembly / disassembly mechanisms are symmetrically arranged and a guide shaft 14 is provided between the two assembly / disassembly mechanisms.

[0029] The loading and unloading mechanism includes a guide rod 9 and a linear slide rail assembly 13. The linear slide rail assembly 13 includes a guide rail and a slide table. The guide rail of the linear slide rail assembly 13 is connected to the base 4 by screws, and the slide table of the linear slide rail assembly 13 is connected to the loading and unloading base 10 by screws.

[0030] Meanwhile, a guide surface 101 is provided on one side of the front end face of the loading and unloading base 10, and a stop pin 12 is fixedly connected to the front end of the loading and unloading base 10 on one side of the guide surface 101 by screws. A placement plate is fixedly installed on the front end of the loading and unloading base 10 on one side of the stop pin 12, and a second fixing column 106 is fixedly installed on the top of the placement plate.

[0031] Furthermore, one end of the stop pin 12 passes through the base 4, and a guide groove is provided on one side of the stop pin 12. Both sides of the guide shaft 14 pass through the guide grooves of the corresponding stop pin 12 and are connected with snap rings. The snap rings facilitate the locking and fixing of the guide shaft 14 and the guide groove of the stop pin 12. The base 4 is provided with a limit sliding groove at the corresponding stop pin 12.

[0032] Meanwhile, on both sides of the top of the base 4, a first fixing post 41 is fixedly installed in front of the corresponding second fixing post 106. A tension spring 11 is provided between the first fixing post 41 and the second fixing post 106. Both ends of the tension spring 11 are provided with hooks. One end of the tension spring 11 is connected to the first fixing post 41 of the base 4, and the other end of the tension spring 11 is connected to the second fixing post 106 of the loading and unloading base 10. Through the tension spring 11, the loading and unloading base 10 can reciprocate along the slide rail assembly 13 above the base 4.

[0033] Furthermore, a first groove 102 is provided on one side of the top surface of the loading and unloading base 10, a second groove 103 is provided on the side of the top surface of the loading and unloading base 10 in front of the first groove 102, a third groove 105 is provided on the side of the top surface of the loading and unloading base 10 in front of the second groove 103, and a V-shaped stop groove 104 is provided on the top surface of the loading and unloading base 10 between the second grooves 103.

[0034] The starting end of the second slide groove 103 is lower than the ending end of the first slide groove 102, while the ending end of the third slide groove 105 is higher than the ending end of the first slide groove 102. The starting end of the third slide groove 105 is flush with the ending end of the second slide groove 103 and the V-shaped stop groove 104. This makes it easier for the guide rod 9 to slide smoothly along the first slide groove 102, the second slide groove 103, the V-shaped stop groove 104 and the third slide groove 105. The guide rod 9 always rotates and slides in a clockwise direction.

[0035] Furthermore, one end of the guide rod 9 is rotatably mounted to the base 4 of the main body unit 1 via a rotating pin. The guide rod 9 is rotatably mounted to the base 4 via the rotating pin, which facilitates the guide rod 9 to rotate freely. The other end of the guide rod 9 is located in the first slide groove 102 of the loading and unloading base 10.

[0036] The bottom surface of the heat sink 6 is connected to the base 4 of the main body unit 1 by screws on all four sides, and the heat conduction plate 8 is connected to the heat sink 6 and the heat conduction plate 7 by screws. The spring piece 5 is connected to the base 4 of the main body unit 1 by screws. The spring piece 5 includes a fixed mounting plate. Multiple V-shaped spring pieces are provided at equal intervals on one side of the fixed mounting plate, and the base 4 has through holes at the multiple V-shaped spring pieces of the spring piece 5.

[0037] In this invention, the user inserts the heat-dissipating optical module into the heat sink 6. At this time, the bottom of the optical module contacts the spring 5. Then, the optical module is further inserted into the heat sink 6. At this time, the left and right sides of the optical module are opened to contact the guide surface 101 of the loading and unloading base 10 of the corresponding loading and unloading mechanism.

[0038] Then, the optical module is continued to be inserted into the heat sink 6. During the movement of the optical module, the corresponding mounting base 10 is moved to one side of the guide rod 9, which causes the guide rod 9 to rotate under the action of the rotating pin. At the same time, since one end of the guide rod 9 is located in the first slide groove 102 of the mounting base 10, the guide rod 9 moves along the first slide groove 102 of the mounting base 10.

[0039] As the optical module continues to be inserted into the heat sink 6, its guide rod 9 moves along the first slide groove 102 of the mounting base 10 and moves to the corresponding second slide groove 103 of the mounting base 10, thus stopping the movement of the optical module.

[0040] Next, as the stop-motion module stops moving, the loading and unloading base 10 moves away from the guide rod 9 under the action of the tension spring 11, thereby causing the guide rod 9 to move along the second slide groove 103 and finally stop in the V-shaped stop groove 104 of the second slide groove 103.

[0041] As the guide rod 9 slides from the first slide groove 102 to the second slide groove 103, the V-shaped spring of the spring 5 moves upward along the corresponding through hole of the base 4, thereby driving the corresponding optical module to move upward, so that the upper surface of the optical module is in contact with the heat-conducting plate 8 until it is completely in contact with the heat-conducting plate 8. When the optical module is completely in contact with the heat-conducting plate 8, the heat of the optical module is guided through the heat sink 6 to the heat sink 7 through the heat-conducting plate 8, and finally the heat is dissipated through the heat sink 7. Thus, the heat of the optical module is guided and dissipated through the heat-conducting plate 8 and the heat sink 7, thereby completing the heat dissipation of the optical module.

[0042] When the optical module needs to be removed, it is inserted further into one side of the heat sink 6. At this time, the optical module drives the corresponding mounting base 10 to move further towards the guide rod 9, thereby causing the guide rod 9 to slide from the second slide groove 103 to the third slide groove 105. When the guide rod 9 moves to the third slide groove 105, it stops moving. At this time, the mounting base 10 moves away from the guide rod 9 under the action of the tension spring 11, thereby causing the guide rod 9 to move along the third slide groove 105 and finally move back to the first slide groove 102. At the same time, the optical module is removed from the heat sink 6 under the action of the guide surface 101 of the mounting base 10, thus making it convenient and quick to remove the optical module from the heat sink 6.

[0043] Meanwhile, during the movement of the loading and unloading base 10, the stop pin 12 corresponding to the loading and unloading base 10 always slides within the limiting sliding groove of the corresponding base 4.

[0045] In this invention, the user dissipates heat from the optical module through the heat dissipation unit 2. When the optical module dissipates heat, the heat dissipation surface of the optical module is in close contact with the heat conduction plate 8 of the heat dissipation unit 2, which facilitates the guiding and dissipation of heat from the optical module and its uniform dissipation. Furthermore, the loading and unloading unit 3 enables the optical module to be loaded and unloaded quickly and accurately, and the operation process is convenient and fast.
