Description

Technical Field

[0001] This invention relates to the field of thermal pad production and processing technology, and in particular to a thermal pad picking device for new energy vehicle manufacturing. Background Technology

[0002] Thermally conductive silicon wafer installation refers to the technical process of installing or laying thermally conductive silicon wafers on or inside electronic components that require heat dissipation, in order to create an efficient heat conduction path and improve overall heat dissipation capacity. In high-heat-generating fields such as new energy vehicle manufacturing, electronics, and power, this process plays a crucial role in ensuring stable operation, performance, and extended lifespan of devices. For example, thermally conductive pads are commonly used as important thermal management materials in the battery modules and electronic control systems of new energy vehicles.

[0003] Currently, traditional manual or semi-automatic processes still face numerous challenges in actual installation operations. For example, when bonding thermal pads to the surfaces of devices with different shapes, there are common problems such as low handling accuracy, poor material loading efficiency, and difficulty in flexibly adjusting positioning strategies according to curved surfaces or complex structures. These factors not only increase the process complexity of thermal management components in new energy vehicle manufacturing, but also limit the heat dissipation efficiency of materials such as thermal pads in core heat-generating components, ultimately affecting the automation level and thermal reliability of the entire vehicle production.

[0004] The prior art patent document CN222348142U discloses a novel thermally conductive silicon wafer laying device. This device, through the coordinated action of a suction mechanism, a second motor, a limiting rod, a feeding platform, and a storage bin, works by placing the workpiece to be laid with the thermally conductive silicon wafer on the feeding platform. A hydraulic rod pushes the air box downwards, allowing the suction cup to enter the storage bin and contact the thermally conductive silicon wafer. An air pump extracts gas from the air box, creating a negative pressure inside, allowing the suction cup to adsorb the thermally conductive silicon wafer. Subsequently, the hydraulic rod drives the inner rod to reset, facilitating loading. The output of the second motor drives the lead screw to rotate, thereby moving the lead screw slider. The limiting rod limits the movement of the lead screw slider, which in turn moves all its components. This allows for adjustment of the front and rear positions according to laying requirements, thus improving the efficiency of subsequent laying.

[0005] However, this device, which only uses a single suction cup, has the following drawbacks: First, the fixed structure of the single suction cup makes it impossible to flexibly adjust the suction layout and range, making it difficult to stably grip thermal pads of different sizes or shapes. Especially in the manufacturing of new energy vehicles, when dealing with diverse battery modules and electronic control unit heat dissipation pads, it is necessary to frequently change the suction head or reposition it, which seriously affects the production cycle and flexibility. Second, single-point adsorption is prone to stress concentration on soft and easily deformable thermal pads, causing tensile deformation or even tearing. This not only affects the structural integrity of the material, but also leads to air bubbles or poor contact at the interface after application, thereby reducing heat conduction efficiency.

The number and position of the rotating rods 53 and the movable plates 54 correspond to each other, and the corresponding rotating rods 53 and movable plates 54 are rotatably connected.

[0030] The working principle and usage of the present invention are explained in detail below: When the heat-conducting pad inside the storage box 16 is taken to the upper end of the feeding platform 15; Start the first drive motor 14, and drive the threaded rod 13 to rotate through its output shaft. Under the restriction of the movement direction of the movable frame 2 by the bracket 11, the rotating threaded rod 13 can drive the movable frame 2 to move above the storage box 16. According to the size of the heat-conducting pad, the second drive motor 26 is started, and the rotating disk 24 is driven to rotate through its output shaft and gear set. Under the restriction of the movement direction of the movable seat 21 by the telescopic sleeve 22 of the movable frame 2, the rotating disk 24 can drive each movable seat 21 to retract inward or expand outward through the sliding connection between the sliding shaft 23 and the sliding groove 25, so that the position of each suction cup 27 can be adjusted so that the suction cup 27 matches the size of the heat-conducting pad. During the movement of the movable seat 21, the driven wheel 42 will move with it. During this process, through the elastic potential energy of the spring 434, through the rotating shaft 432 and the rotating plate 433, a continuous elastic force can be applied to the tension wheel 43, forcing the tension wheel 43 to automatically adjust its spatial position, thereby compensating in real time for the length change or slack tendency of the transmission belt 4 caused by the displacement of the driven wheel 42, so that the transmission belt 4 is always connected to the outer periphery of the driving wheel 41, the driven wheel 42, and the tension wheel 43. When the heat-conducting pad is picked up, the third drive motor 44 is started. Through its output shaft and the meshing connection between the external gear ring 46 and each internal gear 45, each drive wheel 41 can be driven to rotate. In conjunction with the transmission belt 4, the driven wheel 42 and the external threaded sleeve 33 can be driven to rotate. Under the restriction of the movement direction of the internal threaded sleeve 32 by the insertion connection between the limiting sleeve 31 and the internal threaded sleeve 32, the rotating external threaded sleeve 33 can drive the internal threaded sleeve 32 to move downward through the threaded connection between the external threaded sleeve 33 and the internal threaded sleeve 32, so that the suction cup 27 contacts the heat-conducting pad. During the movement of the movable frame 2, the movable frame 2 can drive each of the rotating sleeves 52 to move through the rotational connection between adjacent rotating sleeves 52 and between the rotating sleeve 52 and the connecting sleeve 51, the rotational connection between the rotating rod 53 and the movable plate 54, and the sliding connection between the movable plate 54 and the bracket 11. Thus, through the rotating sleeves 52, the outer pipe 5 and the air guide cavity 3 can be connected to each other, and the outer pipe 5 can be connected to external air pumps and other equipment. When the external air pump is started, the air at the contact point between the suction cup 27 and the heat-conducting pad can be extracted outward through the limiting sleeve 31 and the internal threaded sleeve 32, thereby achieving the effect of picking up the heat-conducting pad. Finally, starting the third drive motor 44 and rotating its output shaft in reverse will lift the suction cup 27 and the heat-conducting pad. Starting the first drive motor 14 and rotating its output shaft in reverse will move the movable frame 2 and move the heat-conducting pad above the feeding platform 15. Starting the third drive motor 44 and rotating its output shaft in the forward direction will place the heat-conducting pad on the upper end of the feeding platform 15. Finally, starting the external air pump will lower the heat-conducting pad from the suction cup 27, thus completing the heat-conducting pad removal operation.
