[0023] The utility model provides a cooling device for heat conduction silica gel sheet production, including belt conveyor 1, fixed mounting support frame 2 on belt conveyor 1 and install fan no.

[0024] Wherein infrared sensor 6 belongs to the infrared sensor equipment of opposite emission, is formed with infrared emission device and infrared receiving device, two respectively install in the both sides of U-shaped frame 4, and its working principle is when heat conduction silica gel sheet moves to the below of U-shaped frame 4 along with belt conveyor 1, will cause the obstruction of infrared emission device emission infrared, and infrared receiving device cannot receive infrared, at this moment, infrared sensor 6 will produce signal change.

[0025] In the embodiment, belt conveyor 1 is used to convey heat conduction silica gel sheet, so that it can pass through cooling area in turn, two fan no. 3 provide the wind power of air cooling, and heat conduction silica gel sheet is preliminarily cooled in movement, and U-shaped frame 4 provides the installation position for electric telescopic rod 5, infrared sensor 6 and other components, and infrared sensor 6 is used to detect the position of heat conduction silica gel sheet, provides trigger signal for subsequent overturning operation, and electric telescopic rod 5 can drive overturning assembly 7 to lift, realizes the fixing and overturning action of heat conduction silica gel sheet, and then creates conditions for realizing double-sided cooling, and the protruding block is equidistantly arranged on the belt of belt conveyor 1, which can increase the friction between the protruding block and heat conduction silica gel sheet, and is beneficial to rapid overturning.

[0026] Specifically, overturning assembly 7 includes the rotating shaft 72 that fixedly connected in the output of electric telescopic rod 5, the outer surface rotationally connected with movable seat 71 of rotating shaft 72, the inside of movable seat 71 is provided with sealed groove 73, and the inside of sealed groove 73 is fixedly installed with fan no. 74, the inside bottom of movable seat 71 is fixedly installed with two suction cups 75, the inside of movable seat 71 is fixedly installed with the communication pipe 76, the inside of suction cup 75 is communicated with the inside of sealed groove 73 through the communication pipe 76, and the inside top of movable seat 71 is fixedly installed with normally open microswitch 77, and normally open microswitch 77 controls the opening and closing of fan no. 74.

[0027] In the embodiment, the rotating connection design of the rotating shaft 72 and the movable seat 71 enables the movable seat 71 to rotate flexibly, and the overturning action of the heat-conducting silica gel sheet is realized by the friction force of the belt conveyor 1 cooperating with the electric telescopic rod 5. The sealing groove 73 is used for installing the fan two 74 and ensuring that the working environment of the fan two 74 is relatively sealed, thereby improving the efficiency of the fan two 74 generating negative pressure. After the fan two 74 is started, negative pressure is formed in the sealing groove 73, which is conducted to the suction cup 75 through the communication pipe 76, so that the suction cup 75 generates suction force to firmly fix the heat-conducting silica gel sheet, and ensure that the heat-conducting silica gel sheet does not fall off during overturning. The normally open micro switch 77 controls the opening and closing of the fan two 74 according to the pressure condition, starts the fan two 74 when it is necessary to fix the heat-conducting silica gel sheet, and closes the fan two 74 after completing the overturning and separating from the heat-conducting silica gel sheet, thereby realizing automatic control and improving the stability and reliability of the device operation.

[0028] Specifically, the input end of the normally open micro switch 77 extends to the top of the movable seat 71, and the inside of the movable seat 71 is provided with a rotating groove. The output end surface of the electric telescopic rod 5 extends into the rotating groove.

[0029] In the embodiment, the input end of the normally open micro switch 77 extends to the top of the movable seat 71, which is convenient for contacting with the U-shaped frame 4. When the movable seat 71 rises to a certain position, it can be pressed in time to close the fan two 74, thereby accurately controlling the working state of the fan two 74. The inside of the movable seat 71 is provided with a rotating groove, and the output end surface of the electric telescopic rod 5 extends into the rotating groove, which not only ensures the stability of the connection between the electric telescopic rod 5 and the movable seat 71, but also does not hinder the rotation of the movable seat 71 around the rotating shaft 72, thereby ensuring the smoothness and reliability of the overturning assembly 7 during the lifting and overturning actions.

[0030] Specifically, the rotating shaft 72 is inserted into the inside of the movable seat 71, and the movable seat 71 is rotatably connected to the outside of the output end of the electric telescopic rod 5 through the rotating shaft 72.

[0031] In the embodiment, the rotating shaft 72 is inserted into the inside of the movable seat 71, thereby providing stable support and a rotating shaft for the rotation of the movable seat 71, so that the movable seat 71 can rotate flexibly around the rotating shaft 72. The movable seat 71 is rotatably connected to the outside of the output end of the electric telescopic rod 5 through the rotating shaft 72, which not only enables the movable seat 71 to rotate, but also enables the electric telescopic rod 5 to smoothly drive the movable seat 71 to rise and fall, thereby realizing a series of coherent actions such as grabbing, overturning and releasing the heat-conducting silica gel sheet, and is a key connection structure for realizing the double-sided cooling operation.

[0032] Specifically, the output end of the fan two 74 faces the outside of the movable seat 71, and the outer surface of the fan two 74 is sealingly attached to the inner wall of the sealing groove 73.

[0033] In the embodiment, the output end of the second fan 74 is directed outward from the movable seat 71, and can discharge air during operation to form a negative pressure inside the sealing groove 73, thereby causing the suction cup 75 to generate suction force to fix the heat-conducting silica gel sheet. The outer surface of the second fan 74 is sealed and attached to the inner wall of the sealing groove 73, which ensures the sealing property of the sealing groove 73, reduces air leakage, improves the efficiency of the second fan 74 in generating negative pressure, and enables the suction cup 75 to more stably and firmly adsorb the heat-conducting silica gel sheet, thereby ensuring the stability of the heat-conducting silica gel sheet during the turning process and avoiding problems such as falling due to insufficient suction force.

[0034] Specifically, the infrared sensor 6 controls the opening and closing of the electric telescopic rod 5 through the controller, and the output end of the first fan 3 is directed toward the belt of the belt conveyor 1.

[0035] In the embodiment, the infrared sensor 6 controls the opening and closing of the electric telescopic rod 5 through the controller, which realizes the automatic operation of the entire device. When the infrared sensor 6 detects that the heat-conducting silica gel sheet enters below the U-shaped frame 4, it can send a signal to the controller in a timely manner, and the controller controls the electric telescopic rod 5 to act, thereby driving the turning assembly 7 to descend and grab the heat-conducting silica gel sheet, which improves the accuracy and efficiency of the operation of the device. The output end of the first fan 3 is directed toward the belt of the belt conveyor 1, so that the blown air can directly act on the heat-conducting silica gel sheet placed on the belt to continuously cool the heat-conducting silica gel sheet. Whether before or after the heat-conducting silica gel sheet is turned, the continuity of cooling can be ensured, the cooling effect is improved, and the product quality is improved.

[0037] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms, and any skilled person in the art can change or modify the equivalent embodiment with the disclosed technical content. However, any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the utility model still belongs to the protection scope of the technical scheme of the utility model.
