[0035] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Reference Figures 1 to 8 As shown, this embodiment provides a heat-conducting sheet bonding device for a vehicle power amplifier, including a frame 8 and a robotic arm assembly 1, a suction head assembly 2, a lifting mechanism 3, a vacuum source 4, a buffer mechanism 5, a first conveying mechanism 6, and a second conveying mechanism 7 mounted on the frame 8.

[0037] The car amplifier 100 is a component of the car audio system. Installed in the vehicle, it provides audio signals to the car speakers to drive them in electroacoustic conversion. For example... Figure 8 As shown, the vehicle amplifier 100 includes a housing 101 and a cover plate 102, which are fastened together by multiple screws. The circuit board 103 of the vehicle amplifier 100 is fixed between the housing 101 and the cover plate 102. The back of the cover plate 102 is provided with multiple heat dissipation fins to dissipate the heat generated on the circuit board. Electronic components, including power amplifiers, are mounted on the circuit board 103. These electronic components generate a significant amount of heat during operation. In this embodiment, a heat-conducting sheet is attached to the back of the circuit board 103 for rapid heat dissipation. The housing 101 has multiple protrusions 1011. Typically, thermal gel is applied to the protrusions 1011 to dissipate heat from the front of the circuit board 103. In other embodiments, the heat-conducting sheet of this embodiment can also be attached to the protrusions 1011 based on product requirements. Both the front and back of the circuit board 103 need to be cooled. In this embodiment, the front of the circuit board faces the protrusions coated with thermal gel, and the back is covered with a heat-conducting sheet. After the heat-conducting sheet is attached, the cover plate 102 is assembled.

[0038] Furthermore, referring to Figure 4As shown, the suction head assembly 2 is used to adsorb the heat-conducting sheet 51. The heat-conducting sheet 51 specifically refers to a silicone sheet, i.e., a thermally conductive silicone sheet, which has good adhesion, flexibility, good compressibility, and excellent thermal conductivity. Specifically, the suction head assembly 2 includes a pressing post 22, a suction head 21 providing negative pressure, and a driving cylinder 23. The bottom of the suction head 21 and the bottom of the pressing post 22 are flush. In other embodiments, the bottom of the suction head 21 may be higher than the bottom of the pressing post 22. The suction head 21 is disposed among multiple pressing posts 22 and is used to pick up the heat-conducting sheet 51. The driving cylinder 23 drives the suction head 21 to move in the vertical direction, combined with... Figure 4 As shown, the drive cylinder 23 is fixed on the mounting bracket 14. When the suction head 21 picks up the heat-conducting sheet 51, the pressing column 22 presses down on the adjacent heat-conducting sheets 51 to prevent them from sticking together.

[0039] The robotic arm assembly 1 is used to drive the suction head assembly 2 to rotate or swing in the horizontal direction. The suction head assembly 2 is movably mounted on the robotic arm assembly 1. Specifically, the robotic arm assembly 1 includes a base 13, a first robotic arm 11 rotatably mounted on the base 13, and a second robotic arm 12 rotatably mounted on the first robotic arm 11 at one end away from the base 13. The first robotic arm 11 and the second robotic arm 12 are rotatably connected around a vertically extending rotation axis to drive the suction head assembly 2 to the vehicle amplifier 100. The second robotic arm 12 is connected to a mounting bracket 14, which moves with the movement of the second robotic arm 12. The mounting bracket 14 is provided with a plurality of suction cups 141, which are used to adsorb the circuit board 103 of the vehicle amplifier 100.

[0040] The lifting mechanism 3 is connected to the suction head assembly 2 and is used to drive the suction head assembly 2 to move in the vertical direction. The lifting mechanism 3 is mounted on the robotic arm assembly 1, specifically on the second robotic arm 12. The lifting mechanism 3 includes a threaded rod 31, which passes through the second robotic arm 12 and is fixedly connected to the mounting bracket 14. The threaded rod 31 has an external thread, and the second robotic arm 12 has an internal thread. The external and internal threads cooperate to drive the suction head assembly 2 to move in the vertical direction. Specifically, the threaded rod 31 is controlled to rotate upward or downward by computer software. When the threaded rod 31 rotates upward or downward, the external and internal threads cooperate to drive the suction head assembly 2 to move in the vertical direction.

[0041] Combination Figure 3 As shown, vacuum source 4 is used to generate negative pressure suction. Vacuum source 4 and suction head assembly 2 are connected by an air pipe. Specifically, vacuum source 4 is a vacuum generator, which transmits the generated vacuum to drive cylinder 23 and suction head 21 through the air pipe. Through the action of vacuum generator, suction head 21 generates suction on the heat-conducting plate to smoothly remove the heat-conducting plate from the buffer mechanism 5.

[0042] The thermal conductive sheet application device also includes a buffer mechanism 5 for placing the thermal conductive sheet 51, which is located beside the first conveying mechanism 6. The buffer mechanism 5 includes a support 52, a buffer placement tray 53 mounted on the support 52, and a lifting cylinder. The buffer placement tray 53 is used to place the thermal conductive sheet 51, and its surface has multiple suction ports 531. The suction ports 531 are connected to a solenoid valve through an air pipe. By controlling the solenoid valve, the thermal conductive sheet 51 to be applied is held in place to prevent displacement. The lifting cylinder is located below and connected to the buffer placement tray 53. During operation, the operator first uses the handle 54 to pull the buffer placement tray 53 out through the guide rail 55, places the thermal conductive sheet 51 to be applied, and then pushes the buffer placement tray 53 into the lifting cylinder through the guide rail 54. The lifting cylinder raises and fixes the buffer placement tray 53 to prevent it from shaking and affecting the adhesion of the thermal conductive sheet 51.

[0043] The first conveying mechanism 6 is used to convey the housing 101 of the vehicle amplifier 100, and the suction head assembly 2 is located above the first conveying mechanism 6. The first conveying mechanism 6 passes under the base 13 to drive the housing 101 to be conveyed sequentially to the area below the suction head 21. Specifically, the first conveying mechanism 6 includes a carrier mounting base 61, which is disposed on the conveyor chain of the first conveying mechanism 6, and the product is transported through the conveyor chain. The housing 101 of the vehicle amplifier 100 is mounted on the carrier mounting base 61 via a carrier 62. The carrier 62 is detachably mounted on the carrier mounting base 61, for example, by means of positioning pins and positioning holes. When replacing the vehicle amplifier, only the carrier 71 needs to be replaced, achieving a quick replacement effect for multiple different models of products. Furthermore, the carrier 62 is provided with multiple positioning blocks 621 and positioning posts 622. The positioning blocks 621 are disposed around the housing 101, and the positioning posts 622 are inserted into the positioning holes of the housing 101. The heat-conducting sheet bonding device also includes a circuit board loading mechanism 9, a second conveying mechanism 7 passing through the loading mechanism and used to transport the circuit board 103 of the vehicle amplifier 100, and a mounting bracket 14 positioned above the second conveying mechanism 7. The mounting bracket 14 is equipped with multiple suction cups 141, which are used to adhere the circuit board 103. Both the first conveying mechanism 6 and the second conveying mechanism 7 include product conveying mechanisms, such as synchronous belt conveyors.

[0044] The thermal pad application device also includes a detection camera for detecting the installation position of the thermal pad and a negative pressure gauge set on the base 13. The detection camera is used to detect whether the installation of the thermal pad meets the requirements, and the negative pressure gauge is used to monitor whether the suction head picks up the silicone sheet, making the application more accurate.

[0045] In this embodiment, the robotic arm assembly 1 controls the suction head 21 to move horizontally, and the lifting mechanism 3 controls the suction head 21 to move vertically. The computer system automatically adjusts the position coordinates of the silicone sheet to be applied according to different product requirements, thereby controlling the application accuracy. When the bonding device is working, it first uses the suction cup 141 on the mounting bracket 14 to adsorb the circuit board 103 on the second conveying mechanism 7 under the coordinated action of the robotic arm assembly 1 and the lifting mechanism 3, and then places the circuit board 103 on the housing 101 of the first conveying mechanism 6. At this time, the front of the circuit board 103 faces the inside of the housing 101, and the back of the circuit board 103 faces the opening of the housing 101. Then, the robotic arm assembly 1 and the lifting mechanism 3 continue to move the suction head assembly 2 to the buffer placement tray 53 of the buffer mechanism 5. The driving cylinder 23 of the suction head assembly 2 drives the suction head 21 to move downward and adsorb the heat-conducting sheet 51. At the same time, the pressing columns 22 around the suction head 21 press the heat-conducting sheet 51 to prevent the surrounding heat-conducting sheets from sticking together with the heat-conducting sheet being adsorbed. Finally, the adsorbed heat-conducting sheet is bonded to the back of the circuit board, completing the entire bonding work. The whole process is automated and has high work efficiency.
