[0024] Example
[0025] like Figure 1 As shown, this embodiment provides an adhesive adsorption device suitable for thin glass sheets. Although this embodiment only describes the bonding of the first thin glass sheet 100 and the second thin glass sheet 200, if it is necessary to bond more layers of thin glass sheets, the same method can be used (adding more thin glass sheet adhesive substrates). The adhesive adsorption device includes: a first thin glass sheet adhesive substrate 1, the panel of the first thin glass sheet adhesive substrate 1 is provided with a first adsorption area 11 adapted to the shape of the first thin glass sheet 100, the first adsorption area 11 is provided with a first pore 12, and the first thin glass sheet adhesive substrate 1 is provided with a first airflow channel communicating with the first pore 12 and the outside, the other end of the first airflow channel is opened on the side wall or bottom wall of the first thin glass sheet adhesive substrate 1; a first vacuum adsorption component, which is connected to the first airflow channel and is used to provide negative pressure for the first adsorption area 11; a second The second sheet adhesive substrate 2 has a second adsorption area on its panel that is adapted to the shape of the second sheet glass 200. The second adsorption area has a second pore. The second sheet adhesive substrate 2 has a second airflow channel that connects the second pore to the outside. The other end of the second airflow channel is opened on the side wall or bottom wall of the second sheet adhesive substrate 2. The second vacuum adsorption component is connected to the second airflow channel and is used to provide negative pressure for the second adsorption area. The first sheet adhesive substrate 1 is adapted to the second sheet adhesive substrate 2.
[0026] If the shapes of the first thin glass sheet 100 and the second thin glass sheet 200 are different, then the corresponding first adsorption area 11 and second adsorption area will also be different. The first thin glass sheet bonding substrate 1 and the second thin glass sheet bonding substrate 2 preferably adopt the same size structure (mainly referring to length and width) to facilitate the fitting and alignment of the first thin glass sheet bonding substrate 1 and the second thin glass sheet bonding substrate 2, and to determine the positions of the first adsorption area 11 and the second adsorption area. Specifically, in the actual adsorption process of the thin glass sheet, it was found that if the pores are only uniformly arranged, the thin glass sheet is prone to edge curling; if a negative pressure is added within the adsorption area, the thin glass sheet is prone to deformation. Therefore, in this embodiment, the first pores 12 distributed on the bottom edge side of the first adsorption area 11 are more densely packed than the first pores 12 in the middle (e.g., ...). Figure 2 (As shown in the figure); the second pores distributed on the bottom edge side of the second adsorption zone are more densely packed than the second pores in the middle.
[0027] Specifically, the method of using the adhesive adsorption device provided in this embodiment is as follows: The first thin glass sheet 100 and the second thin glass sheet 200 are respectively adsorbed onto the first adsorption area 11 and the second adsorption area. Then, the second thin adhesive substrate 2 is flipped and fastened onto the first thin adhesive substrate 1 at a preset position (e.g., ...). Figure 3 As shown), this allows the second thin glass 200 to be bonded to the target position of the first thin glass 100.
[0028] Furthermore, to accurately determine the positions of the first adsorption area 11 and the second adsorption area, the adhesive adsorption device further includes a first gauge block 3 and a second gauge block 4. Multiple first gauge blocks 3 are disposed on two adjacent edge sides of the first adsorption area 11, and the first gauge blocks 3 are detachably connected to the first thin-film adhesive substrate 1. Multiple second gauge blocks 4 are disposed on two adjacent edge sides of the second adsorption area, and the second gauge blocks 4 are detachably connected to the second thin-film adhesive substrate 2. The gauge blocks measure the distance between the edge of the first (second) adsorption area and the side edge of the first (second) thin-film adhesive substrate. Based on the aforementioned first gauge blocks 3 and second gauge blocks 4, the accuracy of the positions of the first adsorption area 11 and the second adsorption area can be ensured, guaranteeing the accuracy of the bonding of the first thin-film glass 100 and the second thin-film glass 200. In addition, based on the first gauge block 3 and the second gauge block 4 mentioned above, the convenience of placing the first thin glass 100 or the second thin glass 200 can be improved. For example, when placing the first thin glass 100 into the first adsorption area 11, the user first makes the two adjacent sides of the first thin glass 100 abut against the corresponding first gauge block 3, and then puts it in vertically, so that the first thin glass 100 can be aligned with the first adsorption area 11.
[0029] Furthermore, such as Figure 1 and Figure 2As shown, the above-mentioned adhesive adsorption device also includes side abutment blocks 5. The first thin sheet adhesive substrate 1 is placed horizontally, with the opening of the first air hole 12 facing upwards. There are multiple side abutment blocks 5, and each of the multiple side abutment blocks 5 abuts against two adjacent side walls of the first thin sheet adhesive substrate 1. The side abutment blocks 5 can help align the second thin sheet adhesive substrate 2 with the first thin sheet adhesive substrate 1. Similar to the process of placing the thin sheet glass, when flipping the second thin sheet adhesive substrate 2 onto the first thin sheet adhesive substrate 1, the two adjacent side edges of the second thin sheet adhesive substrate 2 abut against the corresponding side abutment blocks 5, so that the first thin sheet adhesive substrate 1 and the second thin sheet adhesive substrate 2 are aligned.
[0030] Furthermore, the adhesive adsorption device also includes multiple abutment blocks 6, which are distributed on the other two sidewalls of the first thin-film adhesive substrate 1 (excluding the side abutment block 5). Each abutment block 6 abuts against the sidewall of the first thin-film adhesive substrate 1. The abutment block 6 can cooperate with the side abutment block 5 to fix the first thin-film adhesive substrate 1, preventing displacement of the first thin-film adhesive substrate 1 during the placement of the first thin-film glass 100 and the fastening of the second thin-film adhesive substrate 2, thus affecting the bonding accuracy and efficiency. Furthermore, the height of the abutment block 6 is lower than that of the first adhesive substrate, reducing the vertical space occupation, so as to facilitate the fastening of the second thin-film adhesive substrate 2 onto the first thin-film adhesive substrate 1. The height of the side abutment block 5 is higher than that of the first adhesive substrate, so that the second thin-film adhesive substrate 2 abuts against the side abutment block 5, playing an auxiliary positioning role.
[0031] The above structure can only control the bonding position of the first thin glass sheet 100 and the second thin glass sheet 200 on the horizontal plane. In this embodiment, a height control block 7 is also provided to control the bonding gap (i.e., the thickness of the adhesive) between the first thin glass sheet 100 and the second thin glass sheet 200. Specifically, the bonding adsorption device also includes multiple height control blocks 7, which are evenly distributed and fixed to the first wall of the first thin glass sheet bonding substrate 1. The first wall is the wall where the first adsorption area 11 is located.
[0032] Preferably, in this embodiment, the bonding and adsorption device further includes a metal pipe connector 8 connected to the other end outlet of the first or second airflow channel. The metal pipe connector 8 connects to the first or second vacuum adsorption assembly, ensuring stable negative pressure delivery. The first or second vacuum adsorption assembly includes: an adjustable vacuum pump (with adjustable negative pressure to accommodate thin glass sheets of different thicknesses), a vacuum pipe connecting the adjustable vacuum pump and the metal pipe connector 8, and a vacuum valve on the vacuum pipe for controlling its opening and closing. Furthermore, since the second adsorption area needs to remain in an adsorption state during the flipping and moving of the second thin-sheet bonding substrate 2, the pipe used to deliver negative pressure is preferably expandable and contractible in all directions. Preferably, the vacuum pipe is a corrugated metal pipe, which ensures stable negative pressure delivery and prevents pipe deformation during the operation of the adjustable vacuum pump.
[0033] Specifically, the method of using the adhesive adsorption device provided in this embodiment is as follows: the first thin glass 100 and the second thin glass 200 are respectively embedded in the first adsorption area 11 and the second adsorption area, then the first gauge block 3 and the second gauge block 4 are removed, the second thin adhesive substrate 2 is flipped over and positioned by the side abutment block 5, and it is fastened to the first thin adhesive substrate 1, so that the second thin glass 200 can be bonded to the target position of the first thin glass 100.
[0034] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0035] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
