[0032] See also Figures 1 to 4 The frame assembly 90 includes a supporting frame 93 having an overlapping section 92 and a guide slide 91 passing through the overlapping section 92 and arranged horizontally; it can be understood that the horizontal extension or movement of the guide slide 91 in the overlapping section 92 is not restricted, while the vertical extension or movement of the guide slide 91 in the overlapping section 92 is restricted.

[0033] See also Figures 1 to 4The stacking assembly 94 includes a lower press platform 811 that is slidably arranged in the stacking interval 92 along the vertical direction, an upper press platform 943 that is slidably arranged on the guide slide 91 along the horizontal direction, and an upper press driving mechanism 942 that is located below the lower press platform 811 and is used to drive the upper press platform 943 to rise and fall; it can be understood that the material is placed on the upper press platform 943, and the upper press platform 943 can slide in the vertical direction and detach from the guide slide 91 under the action of external force, and the upper press platform 943 is reset to the guide slide 91 after the external force is removed.

[0034] See also Figures 1 to 4 , wherein the upper press platform 943 has a first position state and a second position state. When the upper press platform 943 is in the first position state, the upper press platform 943 is located in the overlapping section 92, and the upper pressure driving mechanism 942 drives the upper press platform 943 to move upward and close the lower press platform 811.

[0035] It can be understood that the upper pressing platform 943 can be connected to the guide slide 91 through the guide slide 941, the guide slide 941 is horizontally slidably connected to the guide slide 91, and the guide slide 941 is also used to guide the upper pressing platform 943 to move in the vertical direction.

[0036] Optionally, a heating tube is arranged on the upper pressing platform 943, and the material can be heated by the heating tube to achieve full pressing of the material.

[0038] Optionally, the first gravity plate 934 and the second gravity plate 932 are both relatively thick, for example, the thickness may be 20 cm, 30 cm or 50 cm, so that the first gravity plate 934 and the second gravity plate 932 can both withstand relatively large pulling force to achieve sufficient lamination of the materials.

[0039] See also Figures 1 to 4 Optionally, four columns 931 are provided, and the four columns 931 are respectively located at four right angles of the first gravity plate 934 and the second gravity plate 932, and the upper pressing drive mechanism 942 is located directly below the lower pressing platform 811. When the upper pressing platform 943 is located in the overlapping interval 92, the upper pressing drive mechanism 942 pushes the upper pressing platform 943 upward.

[0040] In some embodiments, the guide slide 91 is connected to the first gravity plate 934 .

[0041] Optionally, the guide slide 91 may be detachably connected to the first gravity plate 934 by screws or bolts.

[0042] See also Figures 1 to 4 In some embodiments, an avoidance hole is opened at the position of the first gravity plate 934 corresponding to the upper pressure driving mechanism 942, and the upper pressure driving mechanism 942 includes an upper pressure driver 9421, a pushing column connected to the upper pressure driver 9421, and a pushing plate 9422 located above the first gravity plate 934, and the upper end of the pushing column passes through the avoidance hole and is connected to the pushing plate 9422.

[0043] Optionally, the upper pressure driver 9421 is a hydraulic cylinder, which is a device that converts liquid pressure into mechanical motion or force, and can generate relatively large pressure to fully laminate the material.

[0044] See also Figures 1 to 4 Optionally, the push plate 9422 abuts against the upper pressing platform 943 upward to drive the upper pressing platform 943 to move in the vertical direction to abut against the lower pressing platform 811. When the lower pressing platform 811 moves upward to the extreme position, the upper pressing platform 943 and the lower pressing platform 811 press the material together.

[0045] See also Figures 1 to 4 In some embodiments, the guide slide 91 includes two slide rails 911 arranged in parallel, each of the slide rails 911 passes through the overlapping section 92, and the two ends of the upper pressing platform 943 are slidably connected to the two slide rails 911 respectively.

[0046] See also Figures 1 to 4 Optionally, the length direction of the slide rails 911 is arranged in the horizontal direction, and any slide rail 911 is connected to the first gravity plate 934. The upper pressing platform 943 slides back and forth along the two slide rails 911 to switch between the first position state and the second position state.

[0047] See also Figures 1 to 4In some embodiments, the lower pressing platform 811 includes an adsorption plate 8111, a heating element 8114 and an insulation plate 8115, and the adsorption plate 8111, the heating element 8114 and the insulation plate 8115 are arranged in sequence from bottom to top along the vertical direction.

[0048] See also Figures 1 to 4 It can be understood that the adsorption plate 8111 is used to adsorb the white film unit or the dielectric layer unit from the external peeling structure, and stack the white film unit or the dielectric layer unit on the upper pressing platform 943. The material of the heat insulation plate 8115 is a heat insulation material, such as asbestos. The heat insulation plate 8115 can block the heat from being conducted upward, and prevent other structural parts from overheating or heat loss.

[0049] In some embodiments, a plurality of vacuum adsorption holes 803 are provided on the lower surface of the adsorption plate 8111 , and the vacuum adsorption holes 803 are arranged at intervals.

[0050] Optionally, each vacuum adsorption hole 803 is connected to a vacuum pump, so that the white film unit or the medium layer unit can be adsorbed by the negative pressure principle.

[0051] See also Figures 1 to 4 In some embodiments, the lower surface of the adsorption plate 8111 has a first adsorption area 801 and a second adsorption area 802 , and the aperture of the vacuum adsorption hole 803 located in the first adsorption area 801 is larger than the aperture of the vacuum adsorption hole 803 located in the second adsorption area 802 .

[0052] It is understandable that the vacuum adsorption holes 803 with small apertures have small suction force, while the vacuum adsorption holes 803 with large apertures have large suction force. When adsorbing the dielectric film unit, some areas of the dielectric film unit are printed with patterns. In order to prevent the pattern from being stretched and deformed due to excessive adsorption force, the vacuum adsorption holes 803 of the second adsorption area 802 adsorb the pattern position of the dielectric film unit, while the first adsorption area 801 adsorbs other positions of the corresponding dielectric film unit to ensure sufficient adsorption force to absorb the dielectric layer unit.

[0053] Optionally, the vacuum adsorption holes 803 of the second adsorption area 802 are denser than the vacuum adsorption holes 803 of the first adsorption area 801 , thereby ensuring sufficient adsorption force.

[0054] See also Figures 1 to 4 In some embodiments, the heating element 8114 includes a first heating plate 8113 having a heating hole, a heating rod arranged in the heating hole, and a second heating plate 8112 detachably connected to the first heating plate 8113, and the adsorption plate 8111 is connected to the second heating plate 8112.

[0055] It can be understood that by separating the first heating plate 8113 and the second heating plate 8112 , the adsorption plate 8111 can be separated, thereby facilitating cleaning and maintenance of the adsorption plate 8111 .

[0056] See also Figures 1 to 4 In some embodiments, a first connecting ear 8117 is provided on the side surface of the first heating plate 8113, a second connecting ear 8118 is provided on the side surface of the second heating plate 8112, and the pressing platform 811 also includes a pressing screw 81 and a locking plate 82, one end of the pressing screw 81 passes through the first connecting ear 8117 and the second connecting ear 8118 and is screwed to the locking plate 82.

[0057] See also Figures 1 to 4 Optionally, a first through slot 83 and a second through slot 84 connected to the first through slot 83 are respectively provided on the first connecting ear 8117 and the second connecting ear 8118, a plurality of first through slots 83 are arranged at intervals, and a plurality of second through slots 84 are arranged at intervals, each first through slot 83 corresponds to a second through slot 84, and a plurality of pressing screws 81 are provided, and each pressing screw 81 passes through a first through slot 83 and a second through slot 84 and is screwed to the locking plate 82.

[0058] The first connecting ears 8117 are disposed at two opposite ends of the first heating plate 8113 , and the second connecting ears 8118 are disposed at two opposite ends of the second heating plate 8112 .

[0059] See also Figures 1 to 4 It can be understood that by realizing a detachable connection between the first heating plate 8113 and the second heating plate 8112 on the side, the convenience of disassembling or installing the first heating plate 8113 and the second heating plate 8112 can be improved, avoiding drilling holes in the insulation plate 8115 to connect the adsorption plate 8111.
