[0025] Specifically refers to a kind of spraying device for silicon-carbon rod terminal conductive coating, including shell 1, the front and rear two side surfaces of shell 1 are all provided with access hole 2 communicated with its interior, a plurality of front and rear parallel guide wheels 3 are rotatably connected on the left side inner wall of shell 1, a plurality of drive motors are arranged on the left side of shell 1 to drive the rotation of guide wheel 3, a pressing shell 4 is arranged on the left side inner wall of shell 1, the front and rear two side surfaces of pressing shell 4 are all provided with through hole 5 communicated with its interior, a pressing mechanism is arranged in pressing shell 4 to press and drive the rotation of silicon-carbon rod, shell 1 is provided with a spraying mechanism for spraying the terminal of silicon-carbon rod, the upper surface of guide wheel 3, through hole 5 and access hole 2 are all at the same horizontal position, in use, the terminal of silicon-carbon rod is inserted into shell 1 through rear access hole 2, and finally reaches the upper surface of guide wheel 3, at this time, the drive motor drives the rotation of guide wheel 3, so that the silicon-carbon rod can be transported to through hole 5, and the terminal of silicon-carbon rod passes through pressing shell 4, at this time, the spraying mechanism can spray conductive coating on the surface of terminal of silicon-carbon rod, when the terminal of silicon-carbon rod is sprayed, the drive motor drives the rotation of guide wheel 3 again, so that the terminal of silicon-carbon rod can be stretched out through front access hole 2, therefore, the staff or mechanical hand can take out the silicon-carbon rod after spraying, so as not to affect the subsequent insertion of silicon-carbon rod, the above-mentioned way does not need to use clamp to clamp silicon-carbon rod, simplifies the operation steps when spraying the terminal of silicon-carbon rod, can continuously spray silicon-carbon rod, guarantees the efficiency and speed when spraying coating on the terminal of silicon-carbon rod.

[0026] The spraying mechanism includes a paint storage tank 6, which is arranged outside the shell 1. A pump 7 is arranged on the paint storage tank 6 to extract the paint inside. The output port of the pump 7 is connected to a delivery hose 8. The other end of the delivery hose 8 is slidably inserted into the shell 1 through the upper surface of the shell 1. One end of the delivery hose 8 inside the shell 1 is provided with a spray head 10. In use, the paint in the paint storage tank 6 is extracted by the pump 7. The paint is delivered to the spray head 10 through the delivery hose 8 and finally sprayed onto the outer surface of the terminal of the silicon-carbon rod by the spray head 10.

[0027] An electric push rod 9 is arranged on the upper surface of the shell 1. The lower end of the telescopic rod of the electric push rod 9 is slidably inserted into the shell 1. A connecting plate 11 is arranged on the lower end of the telescopic rod of the electric push rod 9. The other side of the connecting plate 11 is sleeved on the outer surface of the spray head 10. Therefore, when the electric push rod 9 is started, the telescopic rod of the electric push rod 9 can control the downward displacement of the spray head 10, so that the paint sprayed by the spray head 10 can better adhere to the surface of the terminal of the silicon-carbon rod.

[0028] The clamping mechanism includes a square rod 51, the upper end of the square rod 51 is rotatably connected to the top wall of the clamping shell 4, and the upper surface of the clamping shell 4 is provided with a motor 52 for controlling the rotation of the square rod 51. The outer surface of the square rod 51 is slidably sleeved with a sleeve 53. When the motor 52 drives the square rod 51 to rotate, since the square rod 51 is square, the sleeve 53 will rotate synchronously with the square rod 51, and the sleeve 53 can slide on the square rod 51.

[0029] The outer surface of the sleeve 53 is rotatably sleeved with a mounting shell 54, and the outer surface of the sleeve 53 located in the mounting shell 54 is sleeved with a first bevel gear 55, and the lower side of the first bevel gear 55 is meshedly connected with a second bevel gear 56, and the front side surface of the second bevel gear 56 is provided with a transmission shaft 57 whose front end rotates and passes through the outer surface of the mounting shell 54, and the front end of the transmission shaft 57 is provided with a pressing wheel 58 for pressing the silicon carbon rod, and the lower surface of the connecting plate 11 is provided with a push rod 59 at the lower end which slides into the pressing shell 4, and the lower end of the push rod 59 is connected to the upper surface of the mounting shell 54. When the electric push rod 9 telescopic rod pushes the nozzle 10 to move downward, the push rod 59 synchronously pushes the mounting shell 54 to move downward, and the sleeve The cylinder 53 slides on the surface of the square rod 51. When the nozzle 10 moves to the specified position, the pinch wheel 58 is squeezed against the surface of the silicon carbide rod, thereby achieving the effect of restricting the silicon carbide rod, avoiding the problem of the silicon carbide rod terminal being loose during spraying, and ensuring the spraying effect of the silicon carbide rod terminal. At the same time, the motor 52 is started, so that the sleeve 53 drives the first bevel gear 55 to rotate, and the second bevel gear 56 rotates synchronously under the meshing transmission of the first bevel gear 55, thereby rotating the pinch wheel 58. In this way, the pinch wheel 58 can drive the silicon carbide rod to rotate, so that the surface of the silicon carbide rod terminal can be coated more comprehensively, avoiding leaving more coating dead corners, and further ensuring the spraying effect on the surface of the silicon carbide rod terminal.

[0030] The outer surface of the pressing wheel 58 is sleeved with a friction ring for increasing friction, so that the pressing wheel 58 can better drive the silicon carbon rod to rotate.

[0031] The working principle of the spraying device for the conductive coating of the silicon carbon rod terminal provided by the utility model is as follows: the terminal of the silicon carbon rod is inserted into the shell 1 through the rear side access hole 2 and finally contacts the upper surface of the guide wheel 3. At this time, the driving motor drives the guide wheel 3 to rotate, so that the silicon carbon rod can be transported to the through hole 5, and the terminal of the silicon carbon rod passes through the clamping shell 4. At this time, the spraying mechanism can spray the conductive coating on the surface of the terminal of the silicon carbon rod. After the spraying of the terminal of the silicon carbon rod is completed, the driving motor drives the guide wheel 3 to rotate again, so that the terminal of the silicon carbon rod extends through the front side access hole 2.
