Specifically, the attaching device includes an attaching tool 1, as shown in fig. 1-6, the attaching tool 1 includes an operation table 10, a first substrate positioning element 20 and a supporting element 30, the operation table 10 has a supporting area 11 for placing a first substrate 2 (such as a display panel), and the operation table 10 is provided with a groove 12 on the outer side of the supporting area 11, as shown in fig. 2. The first substrate positioning element 20 is configured to be disposed in the groove 12, as shown in fig. 1, the height of the first substrate positioning element 20 is greater than the depth of the opening direction of the groove 12, and the first substrate positioning element 20 and the supporting area 11 form a first substrate accommodating space for accommodating the first substrate 2 and positioning the first substrate 2. The support 30 is used for supporting the second substrate 3, the support 30 is used for being disposed on the operation table 10, in a preferred embodiment, the support 30 is used for being disposed in the recess 12, and when the first substrate positioning element 20 and the support 30 are disposed in the recess 12, the support 30 is beyond or flush with the first substrate positioning element 20 along the opening direction of the recess 12. When the first substrate 2 is placed in the support region 11, the opening direction is preferably consistent with the thickness direction of the first substrate 2.
The attaching method for attaching the liquid crystal display screen by using the attaching tool 1 is shown in fig. 7, and comprises the following steps:

s5: and removing the protective film.
In the step S3, the second substrate 3 may be directly placed at the two ends of the support member 30 in a manner approximately parallel to the first substrate 2, at this time, the adhesive may be extruded to the periphery of the support region 11, and the air in the middle region may not be exhausted to form bubbles, which affects the display effect of the liquid crystal display screen.

s32: and gradually approaching the other end of the second substrate 3 to the first substrate 2 until the second substrate 3 and the adhesive layer are attached.
It is understood that step S5 is followed by the step of:
s6: and removing redundant bonding glue on the first base material 2 and the second base material 3 to complete the bonding of the whole liquid crystal display screen.
Specifically, the outer contour of the supporting region 11 coincides with the outer contour of the first substrate 2, if the first substrate 2 is a rectangular structure, the supporting region 11 is a rectangular region, and the projections of the two in the opening direction of the groove 12 coincide, and when the first substrate 2 is placed in the supporting region 11, the portion of the first substrate positioning element 20 extending out of the groove 12 is attached to the sidewall of the first substrate 2. By adopting the structure and the method, the laminating precision and the laminating efficiency of the liquid crystal display screen can be further improved.
The first substrate positioning element 20 may be a column structure, such as a quadrangular prism structure (not shown) or a straight structure (shown in fig. 3), and the quadrangular prism structure or the straight structure may be disposed at each side of the support area 11. In one embodiment, the first substrate positioning element 20 includes an L-shaped structure, as shown in fig. 4, that is, a part of the plurality of first substrate positioning elements 20 may be an L-shaped structure, that is, when the first substrate positioning element 20 is disposed in the groove 12, a projection of the L-shaped structure is an L-shaped structure along an opening direction of the groove 12. In the embodiment where the supporting region 11 is a rectangular region, the L-shaped structural member is disposed at the corner of the supporting region, so that the positioning accuracy of the first substrate 2 can be improved, and the time for installing the first substrate positioning element 20 can be shortened.
It should be noted that the first substrate positioning element 20 may include one or more of a quadrangular prism structure, a straight-line structure, and an L-shaped structure, and when the number of the first substrate positioning elements is multiple, the first substrate positioning element 20 placed in the groove 12 may be selected according to the structure of the attached first substrate 2.
Specifically, in the opening direction of the groove 12, the difference between the height of the first substrate positioning element 20 and the depth of the groove 12 is less than or equal to the total size of the first substrate 2 and the adhesive layer for attaching the first substrate 2 to the second substrate 3, that is, the length of the first substrate positioning element 20 extending out of the groove 12 is less than or equal to the total thickness of the first substrate 2 and the adhesive layer, and preferably, the length of the first substrate positioning element 20 extending out of the groove 12 is equal to the total thickness of the first substrate 2 and the adhesive layer, so as to ensure the positioning accuracy of the first substrate 2 and facilitate the flow of the redundant adhesive.
When the second substrate 3 is placed, the distance between the second substrate 3 and the first substrate 2 is mainly determined by the height of the supporting member 30, in the above opening direction, the difference between the height of the supporting member 30 and the depth of the groove 12 is equal to the total size of the first substrate 2 and the adhesive layer for attaching the first substrate 2 and the second substrate 3, that is, the length of the supporting member 30 extending out of the groove 12 is equal to the total thickness of the first substrate 2 and the adhesive layer, so that the thickness consistency of the adhesive layer at each place can be ensured, and the attaching quality of the display screen is further improved.
The first substrate positioning element 20 and the supporting element 30 may be different components, and in this case, the height of the first substrate positioning element 20 and the height of the supporting element 30 may be equal or unequal in the opening direction. In an embodiment, the first substrate positioning element 20 and the supporting element 30 are the same component, and at this time, in the opening direction, the length of the first substrate positioning element 20 extending out of the groove 12 is equal to the total thickness of the first substrate 2 and the adhesive layer, as shown in fig. 1, the supporting element 30 may be a structural element in any embodiment of the first substrate positioning element 20, that is, the supporting element 30 is used for both supporting the second substrate 3 and positioning the first substrate 2, so that the number of parts of the attaching tool 1 can be reduced, and the processing cost can be reduced.
No matter what structure is adopted by the first substrate positioning element 20 and the supporting element 30, there are a plurality of first substrate positioning elements 20 and a plurality of supporting elements 30, and there is a gap between any two first substrate positioning elements 20, between any two supporting elements 30, and between the first substrate positioning elements 20 and the supporting elements 30, so that when the second substrate 3 is attached to the first substrate 2, there is a gap between any two first substrate positioning elements 20, any two supporting elements 30, and any one first substrate positioning element 20 and any one supporting element 30, which is favorable for the flow of the excess adhesive.
In particular, the first substrate positioning element 20 and the support element 30 are both in positioning and inserting engagement with the recess 12, so that the support element 30, in particular the first substrate positioning element 20, is positioned by the recess 12, thereby ensuring the positioning accuracy of the first substrate 2.
In the embodiment, the first substrate positioning part 20 and the supporting part 30 are made of bakelite, so that the processing accuracy of the first substrate positioning part 20 and the supporting part 30 can be improved, the laminating quality of the liquid crystal display screen is improved, and short circuit or static electricity generation of components on the first substrate 2 or the second substrate 3 can be prevented as far as possible in the laminating process.
The groove 12 may be a continuous groove along the extending direction, or may include a plurality of grooves spaced along the periphery of the support region 11, in an embodiment, the groove 12 is a continuous groove, specifically, the groove 12 is an annular groove or a 3/4 annular groove, such as an annular groove enclosing a rectangle, or a 3/4 annular groove lacking a single edge, it should be noted that, here, the 3/4 annular groove means that two ends of the groove 12 are not connected, for example, when the support region 11 is a rectangular region, the groove 12 may be disposed only around two long sides and one short side of the rectangular region, or the groove 121 may be disposed only around two short sides and one long side of the rectangular region. The groove 12 adopts the continuous structure, so that the bonding glue flowing to each position in the groove 12 can flow mutually, and further the bonding glue can flow into the groove 12 after being extruded, and the flowing of the bonding glue is more controllable. It is worth noting that when the groove 12 is a 3/4 annular groove, the interval between the two ends of the groove 12 is defined as a closed side, and in the process that the second substrate 3 is attached to the first substrate 2 in an inclined attachment mode, the second substrate 3 is first attached to the first substrate 2 at the closed side, and then the other end of the second substrate is gradually close to the first substrate 2, so that the adhesive gradually flows to the part, opposite to the closed side, of the groove 12 after being extruded, and the flow guiding effect on the adhesive is better achieved.
The glass substrate may have a thickness of 15mm to 20mm, such as 15mm, 18mm, 20mm, etc., to improve the stability of the console 10. Accordingly, the maximum depth of the groove 12 may be 3mm to 7mm, such as 3mm, 5mm, 7mm, etc.
In addition, laminating frock 1 still includes second substrate setting element 40, and second substrate setting element 40 sets up in support area 11 outsidely to be connected with operation panel 10, be used for fixing a position second substrate 3, in order to guarantee second substrate 3 and first substrate 2's positioning accuracy, improve liquid crystal display's laminating quality.
Specifically, the second substrate positioning element 40 and the operation platform 10 are attracted by magnetic force, for example, the glass base is a magnetic glass base, and the second substrate positioning element 40 is an iron or magnetic element, which can attract each other.
The specific structure of the second substrate positioning element 40 may refer to the structure of the first substrate positioning element 20, such as an L-shaped structural element or a straight structural element. The positioning of the second substrate positioning element 40 and the operation table 10 can adopt a matching structure of the positioning of the first substrate positioning element 20 and the operation table 10, that is, the operation table 10 is further provided with a groove adapted to the second substrate positioning element 40, and the second substrate positioning element 40 can adopt any structural member of the first substrate positioning element 20; or directly by other positioning means.
