[0047] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of some applications, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0048] like Figure 1 As shown, the flip mechanism includes a bearing assembly 100 and a transfer film assembly 200. The bearing assembly 100 is used to support the product. One of the surfaces of the product is provided with a first adhesive film. When the bearing assembly 100 supports the product, the first adhesive film contacts the bearing assembly 100, and the first adhesive film can be fixed on the bearing assembly 100. The transfer film assembly 200 is used to contact and bond another surface of the product away from the first adhesive film, so that the product can be separated from the first adhesive film, thereby exposing the surface of the product bonded to the first contact film, and realizing the flipping of the bonding surface of the product.

[0049] In some embodiments, the product may be a wafer, and the first adhesive film may be a UV film. When the first adhesive film is a UV film, the first adhesive film may be fixed around a support ring, and the bearing assembly 100 may simultaneously support the support ring.

[0050] Furthermore, the carrying component 100 can move along the first direction, that is, the carrying component 100 can drive the product to move in the first direction, and the transfer film component 200 is arranged on one side of the carrying component 100, and the transfer film component 200 is provided with an adhesive layer. When the carrying component 100 moves along the first direction and approaches the transfer film component 200, the adhesive layer of the transfer film component 200 can adhere to the product on the carrying component 100. Therefore, after the transfer film component 200 adheres to the product on the carrying component 100, when the carrying component 100 moves along the first direction and away from the transfer film component 200, the product can be detached from the first adhesive film fixed by the carrying component 100 and transferred to the transfer film component.

[0051] The first adhesive film may be fixed to the carrier assembly 100 in the following ways: the carrier assembly 100 compresses the first adhesive film by a compressing structure, or adsorbs the first adhesive film by an adsorption structure, or clamps the first adhesive film by a clamping structure, etc. In this way, when the carrier assembly 100 moves to the initial position, the product can be separated from the first adhesive film.

[0052] Alternatively, the carrier assembly 100 can reduce the adhesiveness of the first adhesive film, so that the first adhesive film can be separated from the product, and the first adhesive film is fixed on the carrier assembly 100 .

[0053] It can be seen that in the present application, a carrier component 100 that can move along a first direction is provided, and a transfer film component 200 is provided on one side of the carrier component 100, and the transfer film component 200 is provided with an adhesive layer. Therefore, when the carrier component 100 moves along the first direction, the adhesive layer can bond the product on the carrier component 100, and since the first adhesive film on the product can be fixed on the carrier component 100, and as the carrier component 100 returns to its initial position, the product can be separated from the first adhesive film and transferred to the transfer film component 200, so that the side of the product bonded to the first adhesive film is exposed, thereby realizing the transfer and flipping of the product.

[0054] That is to say, the flipping mechanism of the present application can flip the product so that the side of the product bonded with the first adhesive film can be exposed.

[0055] Furthermore, in some embodiments, the adhesion between the first adhesive film and the product is smaller than the adhesion between the adhesive layer and the product, so that it is convenient for the product to be separated from the first adhesive film and transferred to the adhesive layer.

[0056] For example, in some embodiments, see Figure 2 , the bearing assembly 100 may include a support platform 110, a heating structure (not shown in the figure) and a bearing drive structure 120. Among them, the support platform 110 is used to support the product. It can be understood that the support platform 110 can contact the first adhesive film to which the product is bonded, and in some embodiments, the first adhesive film can also be fixed. The heating structure is connected to the support platform 110 and is used to make the support platform 110 heat up. After the support platform 110 is heated, it can heat the first adhesive film to reduce the adhesion of the first adhesive film, which is conducive to the separation of the product from the first adhesive film. In this way, in some embodiments, when the support platform 110 moves, the product can be separated from the first adhesive film, so that the first adhesive film is fixed on the support platform 110. The bearing drive structure 120 is connected to the support platform 110 so that the support platform 110 can move along the first direction, wherein the bearing drive structure 120 can be a screw drive structure.

[0057] For example, in some embodiments, a plurality of heating structures such as heating rods may be disposed inside the support platform 110 to enable the support platform 110 to generate heat. In other embodiments, the heating structure may also be a heating plate, and the support platform 110 may be disposed on the heating plate.

[0058] See also Figure 2 The bearing assembly 100 may further include a position adjustment driving structure 130, which is drivingly connected to the support platform 110 so that the support platform 110 can move in the second direction and the third direction respectively, and the first direction, the second direction and the third direction are perpendicular to each other. The position adjustment driving structure 130 can adjust the position of the product on the support platform 110 by moving the support platform 110 in the second direction and the third direction, so that the product can be accurately flipped onto the transfer membrane assembly 200.

[0059] Furthermore, in some embodiments, the position adjustment driving structure 130 can also drive the support platform 110 to rotate around its central axis, so that the angular position of the product can be adjusted when the support platform 110 rotates.

[0060] Specifically, the position adjustment driving structure 130 may include a first position adjustment driving member 131 and a second position adjustment driving member 132. The first position adjustment driving member 131 may drive the support platform 110 to move along the second direction, and the second position adjustment driving member 132 may drive the support platform 110 to move along the third direction. In some embodiments, the first position adjustment driving member 131 may drive the second position adjustment driving member 132 to move along the second direction, thereby driving the support platform 110 to move along the second direction. The first position adjustment driving member 131 and the second position adjustment driving member 132 may drive the support platform 110 to move by moving the conveyor belt linearly.

[0061] The position adjustment driving structure 130 may further include a third position adjustment driving member 133, which may drive the support platform 110 to rotate around its central axis. The third position adjustment driving member 133 may use a conveyor belt to drive the support platform 110 to rotate, so that the support platform 110 can rotate around its central axis.

[0062] See also Figure 2 In some embodiments, the first adhesive film is connected by a support ring, which supports the first adhesive film and facilitates the transfer of the first adhesive film and the product on the first adhesive film. For example, the first adhesive film can be fixed around by the support ring, which is a ring-shaped structure with a hollow part. The first adhesive film located in the hollow part is used to support the product, so that it can prevent damage to the product and also support the product.

[0063] In addition, when the support table 110 supports the product, the support table 110 can also support the support ring at the same time.

[0064] Furthermore, the bearing assembly 100 may also include a plurality of positioning structures 140, which are arranged along the circumferential direction of the support platform 110 and can be moved toward the direction close to the support platform 110, and are used to cooperate with the clamping support ring to achieve the positioning and fixation of the support ring. When the support ring is fixed, the first adhesive film is also fixed, which is conducive to the separation of the product and the first adhesive film.

[0065] In addition, a plurality of positioning structures 140 disposed along the circumferential direction of the support platform 110 can move toward a direction close to the central axis of the support platform 110 to cooperate with the centering and clamping support ring.

[0066] See also Figure 2 and Figure 3 The flipping mechanism may also include a stopper assembly 300, which is disposed on one side of the supporting assembly 100, and the transfer membrane assembly 200 is disposed between the stopper assembly 300 and the supporting assembly 100. When the supporting assembly 100 moves along the first direction, the stopper assembly 300 stops the transfer membrane assembly 200, which can facilitate the central axis membrane assembly to bond the product. At the same time, when the central axis membrane assembly is bonded to the product, the transfer membrane assembly 200 will not be deformed.

[0067] Furthermore, a first air avoidance hole 310 is provided on the stop assembly 300 corresponding to the position where the carrying assembly 100 carries the product, and a first rolling assembly 400 is provided on the side of the stop assembly 300 away from the transfer membrane assembly 200. The first rolling assembly 400 can act on the transfer membrane assembly 200 through the first air avoidance hole 310 and can roll on the transfer membrane assembly 200 to apply pressure between the transfer membrane assembly 200 and the product to increase the adhesion between the transfer membrane assembly 200 and the product.

[0068] Specifically, the first rolling assembly 400 can move in the first direction, and the first rolling assembly 400 can move in the second direction and / or the third direction. When the first rolling assembly 400 moves in the first direction, it can act on the transfer film assembly 200 through the first air-avoiding hole 310 to apply pressure to the transfer mold assembly and the product, and then the first rolling assembly 400 can move in the second direction and / or the third direction, so that the entire product can fully contact the transfer film assembly 200. In addition, when the product is a wafer, the wafer may include a plurality of diced grains, and the rolling of the first rolling assembly 400 can ensure that each grain can contact and be bonded to the transfer film assembly 200.

[0069] For example, the first rolling assembly 400 may include a first roller 410, a first roller driving member 420 and a second roller driving member 430, wherein the first roller driving member 420 is drivingly connected to the first roller 410 for driving the first roller 410 to move in a first direction, the second roller driving member 430 is drivingly connected to the first roller 410 for driving the first roller 410 to move in a second direction, or the second roller driving member 430 is drivingly connected to the first roller 410 for driving the first roller 410 to move in a third direction.

[0070] See also Figure 3 In some embodiments, a first limiting groove 320 may be further provided on a side of the stop assembly 300 close to the bearing assembly 100. When the bearing assembly 100 moves along the first direction, the first limiting groove 320 limits the bearing assembly 100 to achieve positioning of the bearing assembly 100.

[0071] Specifically, when the support platform 110 in the bearing assembly 100 drives the product to move along the first direction, the first limiting groove 320 limits the support platform 110 to ensure that the product on the support platform 110 can contact the transfer membrane assembly 200 through the first avoidance hole.

[0072] See also Figure 1 and Figure 6 The present application also provides a film laminating device, including a receiving assembly 500 and the flipping mechanism in the above embodiment. The transfer film assembly 200 can move along the second direction, and the receiving assembly 500 can be arranged on one side of the carrying assembly 100 and correspond to the moving path of the transfer film assembly 200. For example, the receiving assembly 500 can be arranged on one side of the carrying assembly 100 in the second direction. When the transfer film assembly 200 moves along the second direction, it can drive the product to move to one side of the receiving assembly 500, so as to transfer the product to the receiving assembly 500.

[0073] Furthermore, a second adhesive film is supported on the receiving component 500 , and the receiving component 500 can move along the first direction, so that the second adhesive film on the receiving component 500 can adhere to the product on the transfer film component 200 .

[0074] In some embodiments, the second adhesive film on the receiving component 500 can be loaded onto the receiving component 500 by a die-cutting mechanism, for example, the second adhesive film can be clamped onto the receiving component 500 by a clamping jaw, and then the second adhesive film on the receiving component 500 is separated from the second adhesive film on the unwinding structure 220 by a cutter. In other embodiments, the second adhesive film can be loaded onto the receiving component 500 by manual loading.

[0075] Specifically, after the transfer film 210 in the transfer film assembly 200 is bonded with the product, it moves along the second direction to one side of the receiving assembly 500. At this time, the receiving assembly 500 can move along the first direction, so that the second adhesive film on the receiving assembly 500 can be bonded to the product on the transfer film 210, thereby achieving the second adhesive film being re-bonded to the side of the product that is bonded to the first adhesive film.

[0076] In some embodiments, see Figure 5 The transfer film assembly 200 may include a transfer film 210, a reeling structure 220 and a reeling structure 230, and the transfer film 210 can move along the second direction under the action of the reeling structure 220 and the reeling structure 230, wherein the transfer film 210 may be a UV film, and the surface of the transfer film 210 close to the side of the supporting assembly 100 has adhesiveness.

[0077] In some embodiments, the transfer film assembly 200 may further include a stabilizing structure 240, which is disposed between the unwinding structure 220 and the winding structure 230, and the stabilizing structure 240 can move toward the direction close to the transfer film 210, and can act on the transfer film 210 to fix the transfer film 210, and ensure the stability of the transfer film 210 during the bonding process between the transfer film 210 and the product, wherein the stabilizing structure 240 can be a suction cup that can move along the first direction.

[0078] In addition, the receiving assembly 500 may include an adsorption platform 510 and a receiving driving member 520 . The adsorption platform 510 may adsorb the second adhesive film. The receiving driving member 520 is drivingly connected to the adsorption platform 510 , so that the adsorption platform 510 can move along the first direction.

[0079] Further, see Figure 1 In some embodiments, the film laminating device may further include a light assembly 600, which is disposed on a side of the transfer film assembly 200 away from the receiving assembly 500, and is used to reduce the adhesiveness of the transfer film assembly 200 so that the product can be separated from the transfer film assembly 200. When the transfer film 210 is a UV film, the light assembly 600 may be a UV curing lamp. Of course, in other embodiments, when the adhesiveness of the second adhesive film is greater than that of the transfer film 210, the product may also be transferred from the transfer film 210 to the second adhesive film.

[0080] See also Figure 1 and Figure 6 The film laminating equipment may further include a supporting assembly 700, which is disposed between the receiving assembly 500 and the transfer film assembly 200. The supporting assembly 700 can move along a first direction, and a second air avoidance hole 710 (not shown in the figure) is disposed on the supporting assembly 700. The second air avoidance hole 710 is used to enable the product to be transferred from the transfer film assembly 200 to the second adhesive film.

[0081] Furthermore, the film laminating device may further include a second rolling assembly 800, which is disposed on a side of the transfer film assembly 200 away from the support assembly 700, and the second rolling assembly 800 may act on the transfer film assembly 200 through the second air-avoiding hole 710, and may roll on the transfer film assembly 200. The structure of the second rolling assembly 800 may be the same as that of the first rolling assembly 400, and will not be described in detail herein.

[0082] Specifically, the support assembly 700 moves along the first direction to support the transfer membrane assembly 200, and the second rolling assembly 800 can act on the transfer membrane assembly 200 through the second air avoidance hole 710 and can roll on the transfer membrane assembly 200, which helps the product on the transfer membrane assembly 200 to fall off the transfer membrane assembly 200.

[0083] Optionally, a second limiting groove may be provided on the side of the supporting component 700 close to the supporting component 700. When the receiving component 500 moves along the first direction, the second limiting groove limits the receiving component 500 so that the second adhesive film on the receiving component 500 can be accurately bonded to the product through the second air avoidance hole 710.

[0084] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of some applications should be included in the protection scope of some applications.
