[0033] When the device is used to coat the light module with heat dissipation paste, the light module is placed on the feeding tray 11 in turn, and then the device is started. The heat dissipation paste in the storage tank 15 is pumped out by the suction pump and is delivered to the spraying gun 21 through the delivery pipe 22. The light module is coated with heat dissipation paste by the spraying gun 21. During the coating process, the moving frame 13 can drive the spraying gun 21 to reciprocate on the support frame 12 under the action of the electric sliding rail. The feeding tray 11 can reciprocate on the main base 1. The spraying gun 21 can reciprocate on the moving frame 13, so that the light module can be coated with heat dissipation paste. When a group of light modules are coated, the coated light modules are taken out, and the light modules are placed in the feeding tray 11 again.

[0034] With reference to Figures 2-5 The heating structure includes a heating cover 3 fixed on the storage tank 15. The storage tank 15 is provided with a heating box 31 on the side. A flow guide pipe 32 is fixed on one side of the heating box 31. A heating coil pipe 33 is fixed on the end of the flow guide pipe 32 away from the heating box 31. The heating coil pipe 33 is a copper pipe. Copper has good thermal conductivity, so the heating effect of the heating coil pipe 33 on the storage tank 15 can be improved. The heating coil pipe 33 is sleeved on the storage tank and located in the heating cover 3. The end of the heating coil pipe 33 away from the flow guide pipe 32 extends out of the heating cover 3. A dust screen 34 is installed on the side of the heating box 31 away from the flow guide pipe 32. The heating box 31 is provided with a heating assembly inside. The storage tank 15 is provided with a heat equalizing assembly inside.

[0035] The heating assembly includes a driving motor 35 fixed on the lower end of the heating box 31. The driving motor 35 is electrically connected with the control panel 14. The output end of the driving motor 35 extends into the heating box 31 and is fixed with a driving rod 351. The driving rod 351 penetrates the heating box 31 and is rotatably connected with the heating box 31. The driving rod 351 is fixed with an impeller 352. The heating box 31 is provided with a heating element 353 inside. The heating element 353 is electrically connected with the control panel 14. The heating element 353 is a resistance heating wire.

[0036] In use of the device, the resistance heating wire and the driving motor 35 are turned on. When the resistance heating wire works, air is heated. When the driving motor 35 works, the driving rod 351 is driven to rotate, the driving rod 351 drives the impeller 352 to rotate, the air flow rate inside the heating box 31 can be accelerated, so that the heated air is slowly sent into the heating coil 33 through the flow guide pipe 32, the heat of the hot air is transmitted to the storage tank 15 through the heating coil 33, and the temperature of the heat dissipation paste inside the storage tank 15 gradually rises with the continuous delivery of the hot air. By heating the heat dissipation paste inside the storage tank 15, the flowability of the heat dissipation paste can be improved. By improving the flowability of the heat dissipation paste, the adhesion of the heat dissipation paste on the inner wall of the storage tank 15 can be reduced during the gradual reduction of the heat dissipation paste inside the storage tank 15, so that the problem of hardening of the adhered heat dissipation paste and the need for frequent cleaning of the storage tank 15 can be reduced, and the hardened heat dissipation paste can affect the subsequent coating of the heat dissipation paste, which is more conducive to the coating of the optical module by the coating device. Moreover, by heating the heat dissipation paste to improve the flowability, the delivery of the heat dissipation paste can be more conducive, thereby reducing the blockage problem of the delivery pipe 22 and improving the flowability of the heat dissipation paste coating.

[0037] With reference to Figure 2 and Figure 5 The heat equalizing assembly comprises a mounting shaft 36 rotatably connected inside the storage tank 15, and a heat equalizing blade 361 fixed on the mounting shaft 36. A transmission member is arranged between the mounting shaft 36 and the driving rod 351.

[0038] The transmission member comprises a first belt pulley 362 fixed on the upper end of the driving rod 351, and a second belt pulley 363 fixed on the upper end of the mounting shaft 36. The first belt pulley 362 and the second belt pulley 363 are drivingly connected through a transmission belt 364.

[0039] When the driving rod 351 drives the impeller 352 to rotate, the first belt pulley 362 at the end of the driving rod 351 rotates. When the first belt pulley 362 rotates, the second belt pulley 363 at the end of the mounting shaft 36 rotates under the action of the transmission belt 364, so that the mounting shaft 36 drives the heat equalizing blade 361 to rotate. When the heat equalizing blade 361 rotates, the heat dissipation paste inside the storage tank 15 can be stirred, so that the heat dissipation paste is in a stirred state and is uniformly heated, thereby making the flowability more uniform, further reducing the residue on the inner wall of the storage tank 15, and the more uniform flowability can be conducive to the delivery of the heat dissipation paste, without the problem of uneven spraying of the spray gun 21 due to uneven flowability, thereby improving the spraying uniformity.

[0040] With reference to Figure 2 and Figure 5The lower end of the mounting shaft 36 is fixed with a connecting rod 365, the end of the connecting rod 365 away from the mounting shaft 36 is fixed with a vertical rod 366, the end of the vertical rod 366 away from the connecting rod 365 is fixed with a scraping strip 367, and the scraping strip 367 is attached to the inner wall of the storage tank 15. The scraping strip 367 is an elastic rubber strip. The elastic rubber scraping strip 367 can ensure the scraping effect and will not scratch the inner wall of the storage tank 15.

[0041] When the mounting shaft 36 drives the uniform heating blade 361 to rotate, the connecting rod 365 rotates and drives the vertical rod 366 to rotate, so that the scraping strip 367 rotates inside the storage tank 15. The rotating scraping strip 367 attached to the inner wall of the storage tank 15 can continuously scrape the inner wall of the storage tank 15 to remove the attached heat dissipation paste. In combination with heating the heat dissipation paste, the attached heat dissipation paste on the inner wall of the storage tank 15 can be effectively reduced. By scraping the attached heat dissipation paste on the inner wall of the storage tank 15, the hindrance of the attached heat dissipation paste on the inner wall of the storage tank 15 to heat conduction is reduced, the heat transfer is more uniform, the heating uniformity is improved, and the uniformity of the flowability of the heat dissipation paste is improved.

[0042] Referring to Figure 2 The lower end of the cover plate 16 is fixed with a temperature sensor 37, and the temperature sensor 37 is electrically connected with the control panel 14.

[0043] During the heating of the heat dissipation paste, the temperature sensor 37 can monitor the temperature of the storage tank 15. When the temperature reaches the range of 40℃-50℃ (the temperature range value can be set according to the characteristics of the heat dissipation paste), a signal is sent to the control panel 14. After receiving the signal, the control panel 14 sends a control signal to the resistance heating wire to stop working. When the monitored temperature is lower than 35℃, the control panel 14 sends a control signal to the electric heating wire to work, and the storage tank 15 is heated again. Through the form of dynamic heating, the flowability of the heat dissipation paste can be met, and the problem of evaporation of water in the heat dissipation paste caused by continuous heating and affecting normal use can be avoided.

[0044] Working principle: when the device is used to coat the heat dissipation paste on the optical module, the optical module is placed on the feeding tray 11 in turn, and then the device is started. The heat dissipation paste in the storage tank 15 is pumped out by the suction pump and is delivered to the spraying gun 21 through the delivery pipe 22. The optical module is coated with the heat dissipation paste by the spraying gun 21. During the coating process, the moving frame 13 can drive the spraying gun 21 to move back and forth on the support frame 12 under the action of the electric sliding rail, the feeding tray 11 can move back and forth on the main base 1, and the spraying gun 21 can move back and forth on the moving frame 13, so that the optical module can be coated with the heat dissipation paste. When a group of optical modules are coated, the coated optical modules are taken out, and the optical modules are placed in the feeding tray 11 again.

[0045] In use of the device, the resistance heating wire and the driving motor 35 are turned on. When the resistance heating wire works, air is heated. When the driving motor 35 works, the driving rod 351 is driven to rotate, the driving rod 351 drives the impeller 352 to rotate, which can accelerate the air flow rate in the heating box 31, so that the heated air is slowly sent into the heating coil 33 through the flow guide pipe 32, and the heat of the hot air is transmitted to the storage tank 15 through the heating coil 33, so that the temperature of the heat dissipation paste in the storage tank 15 gradually rises. By heating the heat dissipation paste in the storage tank 15, the flowability of the heat dissipation paste can be improved. By improving the flowability of the heat dissipation paste, the adhesion of the heat dissipation paste on the inner wall of the storage tank 15 can be reduced during the gradual reduction of the heat dissipation paste in the storage tank 15, so that the problem of hardening of the adhered heat dissipation paste and the need for frequent cleaning of the storage tank 15 can be reduced, and the problem of the hardened heat dissipation paste affecting the subsequent coating of the heat dissipation paste can be reduced, which is more conducive to the coating of the optical module by the coating device; and by heating the heat dissipation paste to improve the flowability, the heat dissipation paste can be more easily transported, thereby reducing the blockage problem of the delivery pipe 22 and improving the flowability of the heat dissipation paste coating.

[0046] When the driving rod 351 drives the impeller 352 to rotate, the first belt pulley 362 at the end of the driving rod 351 rotates, and under the action of the transmission belt 364, the second belt pulley 363 at the end of the mounting shaft 36 rotates, thereby driving the mounting shaft 36 to rotate the heat blade 361. When the heat blade 361 rotates, it can agitate the heat dissipation paste in the storage tank 15, so that the heat dissipation paste is in an agitated state and is evenly heated, thereby making the flowability more uniform and further reducing the residue on the inner wall of the storage tank 15. The more uniform flowability can facilitate the transportation of the heat dissipation paste and prevent the problem of uneven spraying of the spray gun 21 due to uneven flowability, thereby improving the spraying uniformity.

[0047] Furthermore, when the mounting shaft 36 drives the heat blade 361 to rotate, it drives the connecting rod 365 and the vertical rod 366 to rotate, so that the scraping strip 367 rotates in the storage tank 15. The rotating state of the scraping strip 367 can continuously scrape the inner wall of the storage tank 15 to remove the adhered heat dissipation paste. In combination with the heating of the heat dissipation paste, the adhered heat dissipation paste on the inner wall of the storage tank 15 can be effectively reduced. Furthermore, by scraping the adhered heat dissipation paste on the inner wall of the storage tank 15, heat transmission can be more uniform, the heating uniformity can be improved, and the flowability uniformity of the heat dissipation paste can be improved.
