Detailed implementation manners

[0033] Hereinafter, embodiments of the technical solutions of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solutions of the present application more clearly, and thus are only examples and should not be used to limit the protection scope of the present application.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present application; the terms "including" and "having" and any variations thereof in the specification and the above drawings of the present application are intended to cover non-exclusive inclusion.

[0035] In the description of the embodiments of the present application, technical terms such as "first" and "second" are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity, specific order or primary-secondary relationship of the indicated technical features. In the description of the embodiments of the present application, "a plurality of" means more than two unless otherwise specifically defined.

[0036] Referring to "embodiments" herein means that specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0037] In the description of the embodiments of the present application, the orientation or positional relationship indicated by technical terms such as "width", "thickness", "upper", "lower", "inner", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the embodiments of the present application.

[0038] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "connection" and "fixation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can also be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0039] With the rapid progress of technology, modern electronic devices are constantly developing towards the direction of high efficiency, compactness, and integration. However, this also brings a problem: the accumulation of heat inside the electronic device. If the heat inside the electronic device cannot be effectively dissipated, it will not only seriously affect the performance of the electronic device, but also may cause damage to the electronic device and even pose safety problems.

[0040] As a new type of thermal conductive material, the carbon fiber thermal conductive gasket has excellent thermal conductivity, mechanical strength, and chemical stability, making it the key to solving the above problems. It can quickly disperse and conduct the heat generated inside the electronic device to the radiator or the external environment, effectively reducing the working temperature of the electronic device and improving the stability and reliability of the electronic device.

[0041] However, during the production process of the carbon fiber thermal conductive gasket, due to the cutting process of the carbon fiber thermal conductive gasket, the surface of the carbon fiber thermal conductive gasket often has unevenness, which not only affects the appearance quality of the carbon fiber thermal conductive gasket, but also affects the fitting degree between the carbon fiber thermal conductive gasket and the contact interface, and further has an adverse effect on the thermal conductivity. Therefore, polishing the surface of the carbon fiber thermal conductive gasket to improve its surface flatness is a key link to improve the product quality and performance of the carbon fiber thermal conductive gasket.

[0042] Currently, most of the polishing operations on carbon fiber heat-conducting gaskets use hand-held polishing machines. Among them, there are many influencing factors for hand-held polishing machines. For example, the polishing effect is affected by the polishing force and human factors. Moreover, during the process of the hand-held polishing machine polishing the carbon fiber heat-conducting gasket, since the hand-held polishing machine will exert a force on the carbon fiber heat-conducting gasket, it is easy to cause the carbon fiber heat-conducting gasket to deviate, resulting in uneven or incomplete polishing of the surface of the carbon fiber heat-conducting gasket, and the polishing effect is not ideal.

[0043] To solve the above problems, this embodiment provides a polishing device. Figure 1 It is a schematic structural diagram of the polishing device provided by the embodiment of the present application. Figure 2 It is a partial structural schematic diagram of the polishing device provided by the embodiment of the present application from the first perspective. Figure 3 It is a partial structural schematic diagram of the polishing device provided by the embodiment of the present application from the second perspective. Please refer to Figures 1 to 3 , the polishing device includes a conveying component 100, a negative pressure component 200, and a polishing component 300.

Please refer to Figures 1 to 4 , the conveying component 100 includes at least two rotating rollers 110 and a conveyor belt 120 sleeved outside at least two rotating rollers 110 at the same time.

In addition, there are a plurality of through holes (not shown in the figure) penetrating the thickness direction of the conveyor belt 120 on the conveyor belt 120.

[0045] Figure 5 It is a schematic structural diagram of the negative pressure component 200 in the polishing device provided by the embodiment of the present application. Please refer to Figures 1 to 5 , the negative pressure component 200 is used to generate negative pressure at the through holes on the conveyor belt 120, so that the carbon fiber heat-conducting gasket waiting for polishing part 400 is adsorbed on the conveyor belt 120.

[0046] Figure 6 It is a schematic structural diagram of the polishing component 300 in the polishing device provided by the embodiment of the present application from the first perspective. Figure 7 It is a schematic structural diagram of the polishing component 300 in the polishing device provided by the embodiment of the present application from the second perspective.

This application does not limit the specific material of the workpiece 400 to be polished.

[0048] It should be noted that this application does not limit the number of rotating rollers 110 in the conveying assembly 100. Exemplarily, the number of rotating rollers 110 can be 2, 3 or more, as long as the rotating rollers 110 in the conveying assembly 100 can jointly drive the conveyor belt 120 to rotate.

In addition, since the conveying assembly 100 and the polishing assembly 300 are both provided in the polishing equipment, the operation of conveying and polishing the workpiece 400 to be polished can be realized simultaneously. The polishing operation efficiency is high, and the output end of the conveying assembly 100 after polishing can convey the workpiece 400 to be polished out, which is also convenient for continuous production.

[0051] Furthermore, in some alternative embodiments of this application, the blower 210 is arranged below the conveying assembly 100.

With the above arrangement, powder debris generated after polishing can be intercepted on the end face of the air suction hood 230 away from the air extraction pipe 220, which helps to avoid the situation where the fan 210 is blocked and unable to work. In addition, the air suction hood 230 being detachably connected to the port of the air extraction pipe 220 away from the fan 210 also facilitates timely disassembly and cleaning of the air suction hood 230, the air extraction pipe 220, etc.
