The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Fig. 1 shows a schematic structural view of some embodiments of the thermally conductive sheet production apparatus of the present disclosure. As shown in fig. 1, the heat conductive sheet production apparatus may include an operation table 11, a work table 12, a robot arm 13, and a winding mechanism 14. Wherein winding mechanism 14 may include a first winding assembly 141 and a second winding assembly 142. Here, the operation table 11 may be used to place a plurality of heat conductive sheets. A base film is placed on the table 12. And the robot 13 is located between the operation table 11 and the work table 12. Thus, the robot 13 can attach the heat conductive sheet on the operation 11 to the under film on the table 12. As can be seen from fig. 1, the first winding assembly 141 and the second winding assembly 142 may be disposed at both sides of the table 12, respectively. Wherein the first winding assembly 141 is used to deliver the base film to the work table 12; the second winding assembly 142 is used to package the base film to which the heat conductive sheet is attached into a roll. Therefore, manual operation can be replaced, batch production of the heat-conducting fins is realized, and production efficiency is improved.

It will be appreciated that thermally conductive sheets (also commonly referred to as heat sinks) are generally tacky and relatively soft and easily deformable. And therefore requires special attention in grasping. For example, the robot may grasp the heat conductive sheet by suction. The manner of adsorption is not limited herein.

In some embodiments, as shown in fig. 2A, the front end of the robot 13 may be mounted with at least one suction cup for grasping the heat conductive sheet. Wherein, the size of at least one sucker is usually smaller than that of the heat conducting fin to be grabbed. It should be noted that, this grasping manner does not generally produce marks on the heat conducting sheet, which would affect it.

Further, the front end of the robot 13 may be provided with a plurality of stoppers. The stops may be located around at least one suction cup. These stoppers are movable in a direction toward or away from the front end of the robot arm 13, that is, movable up and down. As can be seen from fig. 2A, the robot arm 13 (suction cup) is in the home position during the process of grasping the heat conductive sheet. As can be seen from fig. 2B, in the process of attaching the grabbed heat conducting sheet to the bottom mold by the manipulator 13, the stoppers located around the suction cup may move downward to press the heat conducting sheet, so that the heat conducting sheet is separated from the suction cup. After the attachment operation is completed, the stoppers may be moved upward to be reset.

As an example, as shown in fig. 3, the heat conductive sheets may be attached to the base film in a sequential arrangement. The distance L1 between the heat-conducting sheet and the left side of the bottom film may be 5 mm. And the spacing distance D between two adjacent heat-conducting sheets can also be 5 mm. Therefore, parameters can be simplified, and the positioning complexity is reduced, so that the working efficiency of the manipulator can be improved.

Optionally, in order to enable the manipulator 13 to implement the above operation procedure, the front end of the manipulator 13 may be further mounted with a visual inspection assembly. Here, the structure of the visual inspection unit is not limited, and the positioning and recognition functions of the robot may be realized. For example, the visual inspection Device may be formed by a Charge-coupled Device (CCD) or a Complementary Metal Oxide Semiconductor (CMOS). In addition, a light source may be installed below the table. And the base film may be made of a transparent material. Thus, the visual detection assembly is facilitated to detect, and the accuracy of the attaching position of the heat conducting sheet is improved.

In some embodiments, as shown in FIG. 1, winding mechanism 14 may further include a third winding assembly 143. The third winding assembly 143 is located between the work table 12 and the second winding assembly 142, and is used for conveying the protective film. Wherein, the protection film is used for covering the heat conduction sheet. Namely, the heat-conducting sheet is positioned between the protective film and the base film. Thus, the heat conducting sheet can be protected and prevented from dust.

In general, the size (diameter) of a raw material (e.g., a base film) is relatively large when the raw material is supplied. While the table 12 is not normally too high. Therefore, in order to ensure that the base film can be well attached to the table 12, the base film on the first winding assembly 141 may be transferred to the table 12 through the lower portion of the first winding assembly 141. Below here generally refers to the direction towards the ground. Meanwhile, the first winding assembly 141 and the second winding assembly 142 may have the same rotational direction. That is, the base film to which the heat conductive sheet is attached is wound into a roll through the lower portion of the second winding assembly 142. This maintains the carrier film under tension. Of course, in some application scenarios, if the height of the working platform is sufficient, or the bottom film is split (each roll has a smaller diameter), the bottom film on the first winding assembly 141 may also be conveyed to the working platform 12 through the top of the first winding assembly 141.

Further, the heat conductive sheet production apparatus may further include an adjustment mechanism for adjusting the height of the first winding member 141. Wherein the first winding assembly 141 is mounted on the apparatus main body through an adjusting mechanism. For example, the adjustment mechanism may adjust the height between the lower side of the first winding assembly 141 and the apparatus main body according to the rotation speed and the production time period of the first winding assembly 141. For another example, a weight detecting unit may be further provided on the apparatus main body to detect the weight of the base film on the first winding member 141. At this time, the adjusting mechanism may adjust the height between the lower side of the first winding assembly 141 and the apparatus main body according to the detection result of the weight detecting assembly.

It will be appreciated that the lighter the detected weight, as production proceeds, indicates that the smaller the diameter of the carrier film wound on the first winding member 141. I.e. the distance between the carrier film and the table top of the table 12 becomes larger. That is, as the detected weight decreases, the adjustment mechanism may lower the height of first winding assembly 141.

Optionally, the heat conductive sheet production apparatus further includes a detection assembly located below the first winding assembly 141 for detecting the height of the first winding assembly 141. As an example, the detection component may be a distance sensor. Here, the distance sensor may be classified into an optical distance sensor, an infrared distance sensor, an ultrasonic distance sensor, and the like according to an operation principle.

It should be noted that the diameter of the base film wound on the first winding member 141 is smaller as the production is progressed. I.e. the distance between the lower side of the first winding member 141 and the sensing assembly becomes larger. At this time, the adjusting mechanism may lower the height of the first winding assembly 141.

In some embodiments, to further improve the production efficiency, a plurality of heat-conducting sheets may be placed on the operation table 11 through a tray. And a fixing component for fixing the tray can be arranged on the operating platform 11. The fixing means of the fixing assembly is not limited here, and for example, mechanical fixing, magnetic fixing, etc. may be used. That is, the securing assembly may include a mechanical securing component or a magnetic securing component. For example, the tray may be made of a metal material. In this case, a plurality of magnetic blocks may be embedded in the surface of the operation table 11. The tray can be fixed by magnetic force, so that the manipulator 13 can smoothly take the heat-conducting fins away from the tray. For another example, the tray may be made of plastic (e.g., a hard plastic film). This approach is advantageous for reducing manufacturing costs. At this time, as shown in fig. 4, fixing blocks may be disposed on upper and lower (or left and right) sides of the console 11. The fixed block is movably connected with the operating platform 11. When the tray needs to be replaced, the fixing block can be manually (or mechanically) adjusted to generate a gap with the operating platform 11, so that the tray can be taken out. When the tray filled with the heat-conducting fins is placed, the fixing blocks can be manually (or mechanically) adjusted again, so that the tray is fixed.

In some embodiments, a protective cover (not shown in fig. 1) may be further installed outside the heat conductive sheet production apparatus, so as to help ensure the cleanliness of the production environment inside the apparatus. In addition, the protective cover can be provided with a window. Meanwhile, a conveying guide rail penetrating through the upper window of the protective cover is further arranged on the equipment main body. The console 11 may be mounted on a conveyor rail to enable movement of the console 11 between inside and outside the protective enclosure.

It is to be understood that, in order to further improve the production efficiency, the heat conductive sheet production apparatus in the present embodiment may alternatively include two of the above-described operation tables 11, which are respectively located on both sides of the robot 13. Here, the specific structure of the winding mechanism is not limited. As an example, the (first, second, third) take-up assembly may include a spool, a reel spool, and a support bracket. Wherein the reel is used for supporting the whole roll of articles. The reel is detachably connected with the reel, and the reel is fixedly connected with the equipment main body through the support frame. The reel here may be an inflatable reel, as an example. The reel can realize the fixed connection with the reel in the inflation state. And the reel can be disassembled when the reel is in an uninflated state. Also for example, the spool may be provided with locating features (e.g., threaded holes and threaded fasteners) for securing the spool.

The winding mechanism may further comprise a drive assembly for driving the winding assembly (spool) in rotation. It will be appreciated that if the three winding

assemblies

141, 142, 143 are rotated in the same direction, the drive assembly may be coupled to the second winding assembly 142 to drive rotation thereof. At this time, the second winding assembly 142 may rotate the first winding member 141 through the base film. And the second winding assembly 142 may rotate the third winding assembly 143 via the protective film. Therefore, the structure of the equipment can be simplified, and the synchronous rotation of the three winding assemblies can be realized.

The foregoing description is only exemplary of the preferred embodiments of the disclosure and is illustrative of the principles of the technology employed. It will be understood by those skilled in the art that the scope of the invention in the embodiments of the present disclosure is not limited to the specific combinations of the above-mentioned features, but also covers other embodiments formed by any combination of the above-mentioned features or their equivalents without departing from the spirit of the present disclosure.
