[0039] refer to Figures 1 to 8 Describes a thermal grease supply mechanism according to an embodiment of the present invention.
[0040] like Figures 1 to 8 As shown, the automatic conductive sheet thermal grease applicator according to an embodiment of the present invention includes: a frame 100; a conductive sheet feeding mechanism 200, which is located at the right end of the frame 100, and has a conductive sheet material strip 800 wound on it. The conductive sheet material strip 800 includes an upper film, a carrier film, and a lower film stacked sequentially, and a conductive sheet 840 is disposed on the carrier film. The upper and lower films are used to protect the conductive sheet 840; a first conveying mechanism 300, which is arranged in a left-right direction and is used to transport the conductive sheet material strip 800 from left to right. The first conveying mechanism 300 has a right end connected to the conductive sheet feeding mechanism 200; the conductive sheet feeding mechanism 200 feeds material to the first conveying mechanism 300; and a thermal grease feeding mechanism 400, which is located at the rear end of the frame 100, and has thermal grease 91 wound on it. 0. A raw material strip, on which thermal grease 910 is placed; a thermal grease attaching mechanism 500, which is mounted on the first conveying mechanism 300, is used to remove the thermal grease 910 from the thermal grease 910 raw material strip from the thermal grease feeding mechanism 400 and attach the thermal grease to the conductive sheet 840 of the first conveying mechanism 300; a receiving mechanism 600, which is provided with... The receiving mechanism 600 is placed on the frame 100 and connected to the left end of the first conveying mechanism 300. The receiving mechanism 600 removes the conductive sheet 840 with thermal grease 910 attached from the carrier film. The packaging mechanism 700 is located at the left end of the frame 100 and is connected to the receiving mechanism 600. The receiving mechanism 600 sends the conductive sheet 840 with thermal grease 910 attached from the carrier film into the packaging mechanism 700 for packaging.
[0041] like Figure 1 As shown, the conductive sheet feeding mechanism 200 is located at the right end of the first conveying mechanism 300, the receiving mechanism 600 is located at the left end of the first conveying mechanism 300, and the thermal grease feeding mechanism 400 is located behind the first conveying mechanism 300. The conductive sheet feeding mechanism 200 and the thermal grease feeding mechanism 400 feed thermal grease to the first conveying mechanism 300 and the thermal grease applying mechanism 500, respectively. The thermal grease applying mechanism 500 efficiently and accurately applies thermal grease 910 to the conductive sheet 840. Then, the receiving mechanism 600 collects the conductive sheets 840 one by one and checks the application of thermal grease 910. Finally, the packaging mechanism 700 packages the qualified finished conductive sheets 840. Thus, this automatic thermal grease applying device can automatically and efficiently apply thermal grease 910 to the conductive sheet 840, improving the processing efficiency of the conductive sheet 840.
[0042] like Figures 1 to 3 As shown, the conductive sheet material strip 800 is wound onto the conductive sheet feeding mechanism 200 on the right side of the frame 100. The upper film winding mechanism 210 winds up the upper film of the conductive sheet material strip 800. After the upper film is removed, the conductive sheet material strip 800 enters the first conveying mechanism 300 to the left. The first conveying mechanism 300 transports the conductive sheet material strip 800 from right to left. A plurality of thermal grease feeding mechanisms 400 are arranged behind the first conveying mechanism. The thermal grease feeding mechanism 400 winds up the thermal grease 910 material strip. A thermal grease attaching mechanism 500 is arranged between the thermal grease feeding mechanism 400 and the first conveying mechanism 300. The thermal grease feeding mechanism 400 feeds material forward. After the thermal grease attaching mechanism 500 takes material from the thermal grease feeding mechanism 400, it attaches the thermal grease 910 to the conductive sheet 840.
[0043] like Figure 4 and Figure 5 As shown, the thermal grease application mechanism 500 includes a robotic arm and a second vision inspection mechanism. The second vision inspection mechanism is electrically connected to the robotic arm. Based on the inspection results of the vision inspection mechanism, the robotic arm removes thermal grease 910 from the thermal grease supply mechanism 400 and accurately applies the thermal grease 910 to the conductive sheet 840. The robotic arm is movably disposed between the first conveying mechanism 300 and the thermal grease supply mechanism 400. The second vision inspection mechanism is electrically connected to the robotic arm and includes a first vision inspection element 521, a second vision inspection element 522, and a third vision inspection element 523. The first vision inspection element 521 faces the feed port of the thermal grease supply mechanism 400, the second vision inspection element 522 faces the robotic arm, and the third vision inspection element 523 faces the conductive sheet 840 on the first conveying mechanism 300. The robotic arm also includes a rotating mechanism 515, which is disposed between the up-and-down moving mechanism 511 and the thermal grease suction cup 514.
[0044] The first visual inspection element 521 is vertically downwards and detects the position of the thermal grease 910 at the feed port of the thermal grease feeding mechanism 400, so that the robot arm can grasp the thermal grease 910 according to its actual position. The second visual inspection element 522 is vertically upwards and detects whether the robot arm's grease suction cup 514 has correctly grasped the thermal grease 910, confirming the relative position of the thermal grease 910 and the grease suction cup 514. The third visual inspection component 523 is vertically positioned above the first conveying mechanism 300. The third visual inspection component 523 is used to observe the position of the conductive sheet 840 on the first conveying mechanism 300. Combined with the observation results of the second visual inspection component 522 and the third visual inspection component 523, the robot arm's up-down movement mechanism 511, left-right movement mechanism 512, forward-backward movement mechanism 513 and rotation mechanism 515 operate, driving the silicone grease chuck 514 to move and rotate, adjusting the orientation of the thermal grease 910 on the silicone grease chuck 514, and accurately attaching the thermal grease 910 to the conductive sheet 840. The actual position and orientation of the thermal grease 910 and the conductive sheet 840 are observed by the first visual inspection component 521, the second visual inspection component 522 and the third visual inspection component 523. The robot arm is driven to complete the action of grasping the thermal grease 910 and accurately attaching the thermal grease 910 to the conductive sheet 840. The attachment process is highly automated and there is no human error, which ensures the accuracy of the thermal grease 910 attachment, improves the quality of the finished conductive sheet 840 and reduces the defect rate.
[0045] like Figure 6 and Figure 7As shown, the conductive sheet 840 with the thermal grease 910 applied is transported to the left by the first conveying mechanism 300 to the receiving mechanism 600. The receiving mechanism 600 includes a carrier film winding mechanism 610 and a lower film winding mechanism 620, both located to the left of the thermal grease application mechanism 500. The carrier film winding mechanism 610 is located above the first conveying mechanism 300, and the lower film winding mechanism 620 is located below the first conveying mechanism 300. The receiving mechanism 600 also includes a gripping mechanism for gripping the conductive sheet 840 with the thermal grease 910 applied to the carrier film. The gripping mechanism includes a turntable 631, with a rotating motor 632 connected to its rear end. Two gripping suction cups 633 are located at the front end of the turntable 631, facing away from each other. The rotating motor 632 drives the turntable 631 to rotate, causing the two gripping suction cups 633 to alternately grip the conductive sheet 840 below the turntable 631. The gripped conductive sheet 840 flips along with the gripping suction cups 633 as the turntable 631 rotates. The receiving mechanism 600 also includes a second conveying mechanism 640, which is arranged in a left-right direction. The right end of the second conveying mechanism 640 is above the gripping mechanism, and the left end is above the packaging mechanism 700. A conveying suction cup is located at the lower end of the second conveying mechanism 640. The conveying suction cup removes the conductive sheet 840 flipped by the gripping suction cup 633 and transports it to the packaging mechanism 700. The receiving mechanism 600 also includes a rejection mechanism, which is positioned facing the second conveying mechanism 640. The rejection mechanism is used to detect the adhesion of thermal grease 910 on the conductive sheet 840 and reject defective products. The rejection mechanism includes a first visual inspection mechanism 651 and a recycling box 652. Both the first visual inspection mechanism 651 and the recycling box 652 are located below the second conveying mechanism 640. The first visual inspection mechanism 651 faces upwards and is used to detect the conductive sheet 840 gripped by the conveying suction cup. The recycling box 652 is located to the left of the first visual inspection mechanism 651.
[0046] The carrier film winding mechanism 610 peels the carrier film from the conductive sheet material strip 800 upwards and winds it up. The lower film winding mechanism 620 peels the lower film from the conductive sheet material strip 800 downwards and winds it up. The gripping suction cup 633 grips the conductive sheet 840 with thermal grease 910 already applied on it. The rotating motor 632 drives the turntable 631 to rotate, which in turn causes the gripping suction cup 633 to rotate 180°. The conductive sheet 840 rotates accordingly, with its bottom surface facing upwards. At this time, the second conveyor... The conveying suction cup in mechanism 640 picks up the conductive sheet 840 and transports the conductive sheet 840 to the left along the second conveying mechanism 640. During the transport, the first visual inspection mechanism 651, which is set vertically upward, checks the adhesion of the thermal grease 910 on the conductive sheet 840. When a defective product is detected, the conveying suction cup releases the conductive sheet 840 when it moves above the recycling box 652, so that the defective product falls into the recycling box 652. The conductive sheet 840 that passes the inspection by the first visual inspection mechanism 651 continues to be transported to the left to the packaging mechanism 700.
[0047] like Figure 8 As shown, the packaging mechanism 700 includes a sealing mechanism 710, which is used to seal and preserve the processed conductive sheet 840. The second conveying mechanism 640 transports the qualified conductive sheet 840 to the packaging mechanism 700, where the sealing mechanism 710 seals and packages the conductive sheet 840.
[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
