[0029] Please refer to Figures 1 to 3 The present embodiment provides a pressing carrier, which includes a base 10 and a cover plate 20. The base 10 is provided with a first receiving groove 13 and a second receiving groove 111 which are connected to each other. The first receiving groove 13 and the second receiving groove 111 are arranged along a first direction a, and the first direction a is the arrangement direction of the cover plate 20 and the base 10. The first receiving groove 13 is used to place the substrate to be pressed, and the cover plate 20 is received in the second receiving groove 111. The cover plate 20 is used to cooperate with the base 10 to press the substrate to be pressed in the first receiving groove 13. The pressing carrier can perform double-sided pressing, thereby improving the working efficiency.

[0030] The lamination carrier provided by the present application includes a base 10 and a cover plate 20. The base 10 is provided with a space for placing the substrate to be laminated (i.e., the first accommodating groove 13) and a space for accommodating the cover plate 20 (i.e., the second accommodating groove 111). In this way, the substrate to be laminated can be placed in the first accommodating groove 13, and then the cover plate 20 is covered in the second accommodating groove 111, so that the substrate to be laminated can be laminated on both sides through the cooperation of the cover plate 20 and the base 10. This setting method of the present application, on the one hand, can realize the double-sided lamination of the substrate to be laminated, which can improve the working efficiency; on the other hand, the double-sided lamination method can improve the problem of warping of the substrate to be laminated.

[0031] It should be noted that when the cover plate 20 is installed in the second receiving groove 111 , a surface of the cover plate 20 close to the base 10 can act on the substrate to be pressed, thereby cooperating with the base 10 to press and fix the substrate to be pressed.

[0032] In addition, it should be noted that the pressing carrier of the present application is not only suitable for double-sided packaging substrates that require double-sided pressing (that is, when the substrate to be pressed is a double-sided packaging substrate), but can also be used for other substrates that require double-sided pressing. The present application does not limit the specific application scenarios of the pressing carrier.

[0033] Please refer to Figure 1 and Figure 2 The base 10 includes a first accommodating groove 13 and a second accommodating groove 111. The first accommodating groove 13 and the second accommodating groove 111 are arranged along a first direction a on the base 10. That is, corresponding to Figure 1 In the orientation shown, the first accommodating groove 13 and the second accommodating groove 111 are arranged vertically.

[0034] The first receiving groove 13 is used to place the substrate to be pressed, and the second receiving groove 111 is used to place the cover plate 20. Specifically, the present application does not limit the specific structure of the cover plate 20 and the base 10, as long as the arrangement of the cover plate 20 and the base 10 can realize the pressing and fixing of the substrate to be pressed. Of course, optionally, corresponding heat dissipation holes can also be set on the base 10 and the cover plate 20 to reduce the rapid heat dissipation and cooling of the device on the substrate to be pressed when it is subjected to heat shock, so as to avoid excessive heat causing the substrate to be pressed to warp.

[0035] In summary, the pressing carrier provided by the present application includes a base 10 and a cover plate 20, and the base 10 is respectively provided with a first receiving groove 13 and a second receiving groove 111 which are interconnected; the first receiving groove 13 and the second receiving groove 111 are arranged along a first direction a, and the first direction a is the arrangement direction of the cover plate 20 and the base 10, the first receiving groove 13 is used to place the substrate to be pressed, and the cover plate 20 is received in the second receiving groove 111, and the cover plate 20 is used to cooperate with the base 10 to press the substrate to be pressed located in the first receiving groove 13. By providing the base 10 and the cover plate 20, the present application can perform double-sided pressing of the substrate to be pressed. In this way, when the substrate to be pressed is a double-sided encapsulation substrate, the pressing carrier can perform double-sided pressing of the double-sided encapsulation substrate by the cooperation of the base 10 and the cover plate 20. In this way, on the one hand, the double-sided pressing method can improve the problem of warping of the substrate to be pressed; on the other hand, it can improve the operation efficiency of the double-sided encapsulation substrate.

[0036] Please refer to Figure 2 Optionally, the base 10 includes a first annular body 11 and a first connecting rib 12, the first connecting rib 12 is arranged in the first annular body 11 and connected to the inner wall of the first annular body 11; the first connecting rib 12 and the inner wall surface of the first annular body 11 enclose a first accommodating groove 13; the second accommodating groove 111 is recessed on the first annular body 11, and is located on the side of the first accommodating groove 13 away from the first connecting rib 12.

[0037] The first connecting rib 12 is located on a side of the first annular body 11 away from the cover plate 20 , so that the first connecting rib 12 and the inner wall surface of the first annular body 11 can be combined to form a first receiving groove 13 for receiving the substrate to be pressed.

[0038] The first connecting rib 12 can be provided to press the side of the substrate to be pressed away from the cover plate 20. The shape of the first connecting rib 12 is not specifically limited in this application, as long as it can play a pressing role and does not cause damage to the substrate to be pressed.

[0039] In addition, the first annular body 11 is also recessed with the above-mentioned second accommodating groove 111, so that the cover plate 20 can be at least partially or completely accommodated in the second accommodating groove 111, and the second accommodating groove 111 can also radially limit the cover plate 20, thereby improving the stability of the cover plate 20 during the pressing process.

[0040] Optionally, the first connecting ribs 12 include at least two, and the at least two first connecting ribs 12 are arranged to intersect and cooperate with the inner wall surface of the first annular body 11 to form a plurality of first hollow portions 14 .

[0041] For example, if the first connecting ribs 12 include two, the two first connecting ribs 12 may be cross-arranged to form four first hollow portions 14 with the inner wall surface of the first annular body 11, such as Figure 2 As shown; for another example, two first connecting ribs 12 may also be arranged to intersect in a V shape to form three first hollow portions 14 with the inner wall surface of the first annular body 11. Of course, when the number of the first connecting ribs 12 is three or more, a suitable crossing method can be selected according to the number and position of the required first hollow portions 14, and this application does not limit it.

[0042] In order to reduce the thermal shock of the device on the substrate to be pressed, the device on the substrate to be pressed is quickly cooled to avoid the substrate to be pressed from being warped due to excessive heat, optionally, a plurality of first through holes 121 are provided on the first connecting rib 12, and the axial direction of the first through hole 121 is parallel to the first direction a, such as Figure 1 and Figure 2 shown.

[0043] The plurality of first through holes 121 may be evenly distributed on the first connecting rib 12 .

[0044] In addition, in order to further improve the heat dissipation effect, optionally, a plurality of second through holes 112 may be further provided on the first annular body 11 , and the axial direction of the second through holes 112 is perpendicular to the first direction a.

[0045] It should be noted that the axial direction of the second through hole 112 is perpendicular to the first direction a, so that the axial direction of the second through hole 112 is also perpendicular to the axial direction of the first through hole 121. By setting as above, the present application can dissipate heat from the bottom of the substrate to be pressed through the first through hole 121, and dissipate heat from the side wall of the substrate to be pressed through the second through hole 112, which can improve the heat dissipation uniformity of the substrate to be pressed. Of course, the vertical arrangement of the first through hole 121 and the second through hole 112 is only an example. In other embodiments, the first through hole 121 and the second through hole 112 can also be arranged in parallel according to other needs.

[0046] In this embodiment, the plurality of second through holes 112 may also be evenly distributed on the first annular body 11. Figure 2 shown.

[0047] Please refer to Figure 1 and Figure 3 Optionally, the cover plate 20 includes a second annular body 21 and a second connecting rib 22 , the second connecting rib 22 is disposed in the second annular body 21 and connected to the inner wall of the second annular body 21 ; the second annular body 21 is accommodated in the second accommodating groove 111 .

[0048] The second connecting rib 22 provided on the cover plate 20 can press one side of the substrate to be pressed similarly to the first connecting rib 12. In this embodiment, the second connecting rib 22 is used to press one side of the substrate to be pressed, and the first connecting rib 12 is used to press the other side of the substrate to be pressed.

[0049] The second annular body 21 is received in the second receiving groove 111 , which can improve the stability of the cover plate 20 when pressed.

[0050] Optionally, the second connecting ribs 22 include at least two, and the at least two second connecting ribs 22 are arranged to intersect and cooperate with the inner wall surface of the second annular body 21 to form a plurality of second hollow portions 23 .

[0051] The arrangement of the at least two second connecting ribs 22 may be the same as the arrangement of the at least two first connecting ribs 12 , and reference may be made to the arrangement of the at least two first connecting ribs 12 in the foregoing text, which will not be repeated here.

[0052] In this embodiment, in order to improve the pressing effect, the number of the second connecting ribs 22 can be the same as the number of the first connecting ribs 12, and the second connecting ribs 22 are arranged at positions corresponding to the first connecting ribs 12. For example, if two second connecting ribs 22 are arranged in a cross-shaped arrangement, then two first connecting ribs 12 are also arranged in a cross-shaped arrangement, such as Figure 1 As shown. In this way, the forces on the two opposite sides of the substrate to be pressed are more uniform.

[0053] Optionally, the second connecting rib 22 may be provided with a plurality of third through holes 221, and the axial direction of the third through holes 221 is parallel to the first direction a. Figure 3 In this way, the third through hole 221 can dissipate heat to the side of the substrate to be pressed away from the base 10 .

[0054] To allow temperature convection and reduce thermal shock, optionally, the plurality of third through holes 221 correspond to the plurality of first through holes 121 one by one, see Figure 1 shown.

[0055] Also, optionally, in this embodiment, the side of the second annular body 21 facing away from the base 10 is flush with the side of the first annular body 11 facing away from the first connecting rib 12. Of course, the flush setting is only an example, and in other embodiments, the side of the cover plate 20 facing away from the base 10 (that is, the side of the second annular body 21 facing away from the base 10) may be protruding from the side of the first annular body 11 facing away from the first connecting rib 12.

[0056] The above description is only an optional embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
