[0044] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] The utility model embodiment provides a fitting tool, see Figure 1 to Figure 2 , Figure 1 : is a structural schematic diagram of a laminating tool, the laminating tool is used for laminating a flexible board 5 with a curved cover plate 6, and the curved cover plate 6 has curved portions on both sides;

[0046] The extrusion mechanism is arranged on the lifting mechanism 1, and the lifting mechanism is used to drive the extrusion mechanism to rise and fall;

[0047] The support member 4 is arranged on the top of the extrusion mechanism and is used to support the flexible board 5;

[0048] The fixing assembly is arranged above the support member 4 and is used to fix the curved cover plate 6;

[0049] The extrusion mechanism is used to drive the support member 4 to fit the two sides of the flexible plate 5 with the curved parts of the two sides of the curved cover plate 6 .

[0050] It should be noted that since the curved cover plate 6 has curved portions on both sides, the present application sets up an extrusion mechanism, and then after the lifting mechanism 1 drives the support member 4 to rise until the flexible plate 5 and the curved cover plate 6 are in contact, the extrusion mechanism can be used to squeeze the two sides of the flexible plate 5 to fit the curved portions on both sides of the curved cover plate 6.

[0051] It is worth noting that before bonding the flexible board 5 and the curved cover plate 6, it is necessary to first fix the curved cover plate 6 through a fixing assembly, and then place the flexible board 5 on the support 4, and align the marked position of the flexible board 5 with the marked position on the curved cover plate 6, and then bond the curved cover plate 6 and the flexible board 5 through the bonding tool provided in this application.

[0052] In the embodiment of the utility model, the extrusion mechanism is arranged on the lifting mechanism 1, and the lifting mechanism is used to drive the extrusion mechanism to lift and lower, and the support member 4 for supporting the flexible board 5 is arranged on the top of the extrusion mechanism, and the fixing member 2 for fixing the curved cover plate 6 is arranged above the support member 4, and the support member 4 is driven by the extrusion mechanism to fit the two sides of the flexible board 5 with the curved parts on both sides of the curved cover plate 6. Through the above-disclosed bonding tool, since the lifting mechanism 1 can drive the support member 4 to fit the middle part of the flexible board 5 with the middle part of the curved cover plate 6, and after the middle part of the flexible board 5 is fit with the middle part of the curved cover plate 6, the support member 4 can be driven by the extrusion mechanism to fit the two sides of the flexible board 5 with the curved parts on both sides of the curved cover plate 6, not only the bonding difficulty is effectively reduced, but also the bonding steps can be reduced. Therefore, through the bonding tool provided by the present application, the bonding efficiency and yield rate of the curved cover plate 6 and the flexible board 5 can be effectively improved.

[0053] Specifically, the support member 4 is made of soft material;

[0054] The top of the support member 4 is an arc-shaped structure with a high middle portion and low sides.

[0055] It should be noted that the top of the support member 4 is an arc-shaped structure with a high middle part and low two sides. After the flexible board 5 is placed on the support member 4, the two sides of the flexible board 5 will droop downward due to their own weight, thereby forming an arc-shaped structure for the flexible board 5. When the lifting mechanism 1 drives the support member 4 to rise to the top of the flexible board 5 and contacts the curved cover plate 6, only the middle part of the flexible board 5 is in contact, that is, only line contact. At this time, the lifting mechanism 1 continues to drive the support member 4 to rise. As the support member 4 rises, the flexible board 5 and the curved cover plate 6 gradually change from line contact to surface contact. Since the flexible board 5 and the curved cover plate 6 are gradually contacted and bonded from the middle to the two sides, it can effectively avoid the generation of bubbles, pockmarks, white lines and other problems when the flexible board 5 and the curved cover plate 6 are bonded, thereby improving the bonding yield of the curved cover plate 6 and the flexible board 5.

[0056] Specifically, the support member 4 is made of a soft material with elastic deformation.

[0057] It should be noted that the support member 4 is made of a soft material with elastic deformation. After the flexible plate 5 and the curved cover plate 6 are bonded together, the lifting mechanism 1 drives the support member 4 to descend, and the support member 4 can be restored to the arc structure under the action of its own elastic restoring force, thereby achieving reuse and reducing the bonding cost of the flexible plate 5 and the curved cover plate 6.

[0058] Specifically, the soft material is silicone.

[0059] It should be noted that the flexible material can be silicone or other materials that can deform when squeezed and can return to the original state under the action of its own elastic restoring force when the external force is removed. Technical personnel in this field can choose according to needs.

[0060] Further, the support member 4 includes: a first support body 41 and a second support body 42, wherein the sum of the width of the first support body 41 and the width of the second support body 42 is smaller than the distance between the two side bending parts of the curved cover plate 6;

[0065] The second support rod 33 is vertically arranged on the second moving mechanism 35;

[0066] The second support body 42 is disposed on the top of the second support rod 33;

[0067] The first moving mechanism and the second moving mechanism 35 are used to respectively drive the first support rod 32 and the second support rod 33 to move in opposite directions, so as to separate the first support body 41 from or bring the second support body 42 closer to each other.

[0068] It should be noted that the support member 4 is provided with a first support body 41 and a second support body 42, and the sum of the width of the first support body 41 and the width of the second support body 42 is smaller than the distance between the curved portions on both sides of the curved cover plate 6, and the extrusion mechanism is provided as a support plate 31, a first support rod 32, a second support rod 33, a first moving mechanism and a second moving mechanism 35, and the first moving mechanism and the second moving mechanism 35 are movably provided on the support plate 31; the first support rod 32 is vertically provided on the first moving mechanism, the first support body 41 is provided on the top of the first support rod 32, the second support rod 33 is vertically provided on the second moving mechanism 35, and the second support body 42 is provided on the top of the second support rod 33, thereby driving the support member 4 in the lifting mechanism 1 After the middle part of the upper flexible plate 5 is bonded with the middle part of the curved cover plate 6, the first moving mechanism and the second moving mechanism 35 respectively drive the first support rod 32 and the second support rod 33 to move in opposite directions, that is, move toward the curved parts on both sides of the curved cover plate 6 respectively, so that the first support body 41 can be separated from the second support body 42, and the two sides of the flexible plate 5 can be bonded with the curved parts on both sides of the curved cover plate 6 respectively. Finally, the first moving mechanism and the second moving mechanism 35 respectively drive the first support rod 32 and the second support rod 33 to be close, and the lifting mechanism 1 drives the first support body 41 and the second support body 42 to descend and reset, so that the bonded screen can be removed from the fixing member 2, and preparations for bonding the next curved cover plate 6 with the flexible plate 5 can be made.
