The words "example" or "for example" are intended to present a relative concept in a clear manner.

[0043] The embodiments of the present application provide an assembling jig and an assembling method of a backlight module, so as to facilitate the assembling of a reflective sheet and a lamp plate.

[0044] Please refer to Figure 1 and Figure 2 The backlight module 200 includes a lamp plate 21 and a reflective sheet 22 which are bonded to each other.

[0045] The assembling jig 100 includes a jig body 11, a first positioning component 12, and a second positioning component 13. The jig body 11 is used to carry the reflective sheet 22. The first positioning component 12 is arranged on the jig body 11, and is used to position the reflective sheet 22. The second positioning component 13 is arranged on the jig body 11, and is used to position the lamp plate 21 when the lamp plate 21 is bonded to the reflective sheet 22 carried by the jig body 11.

[0046] In the embodiment of the present application, the reflective sheet 22 can be positioned by the first positioning component 12 to be placed on the jig body 11, and then the lamp plate 21 can be positioned by the second positioning component 13 and pasted to the reflective sheet 22 carried by the jig body 11, so that the reflective sheet 22 and the lamp plate 21 can be accurately pasted, and the display effect of the display device can be improved.

[0047] In addition, since the jig body 11 carries the reflective sheet 22 and the first positioning component 12 positions the reflective sheet 22, the reflective sheet 22 can be placed flat on the jig body 11, so that the reflective sheet 22 can be prevented from being wrinkled on the surface of the lamp plate 21 when the reflective sheet 22 is manually pasted to the lamp plate 21, and the pasting of the reflective sheet 22 not only has the advantages of easy operation and high operation efficiency, but also can improve the pasting quality of the reflective sheet 22 to improve the display effect of the display device.

[0048] The above is the overall introduction of the technical solution of the embodiment of the present application, and the technical solution of the embodiment of the present application will be further introduced in combination with the first positioning component 12.

[0049] Please continue to refer to Figure 3 and Figure 4 In some embodiments, the first positioning component 12 includes a positioning pin, and the positioning pin is used to pass through the first positioning hole on the reflective sheet 22 to position the reflective sheet 22.

[0050] In addition, after the positioning pin passes through the first positioning hole of the reflective sheet 22, the positioning of the reflective sheet 22 can be achieved, and the reflective sheet 22 carried on the jig body 11 can not be lifted by the first positioning component 12 to have a local protrusion, so that the reflective sheet 22 can be more flatly pasted to the lamp plate 21.

[0051] In some embodiments, the positioning pin includes an elastic telescopic member, and the elastic telescopic member is telescopically arranged on the jig body 11. In addition, the elastic telescopic member can be deformed adaptively during the assembly of the backlight module 200 to avoid damage of the reflective sheet 22 and / or the lamp plate 21 of the backlight module 200 after colliding with the positioning pin.

[0052] It should be noted that in the embodiment of the present application, the association relationship of the associated objects is described by "and / or", which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone. In addition, the character " / ", if not specially stated, generally represents an "or" relationship between the front and rear associated objects.

[0053] That is, the elastic stretchable member can be deformed adaptively in the process of assembling the backlight module 200, so as to avoid damage of the reflective sheet 22 after colliding with the elastic stretchable member, or avoid damage of the reflective sheet 22 after colliding with the lamp plate 21, or avoid damage of the reflective sheet 22 and the lamp plate 21 of the backlight module 200 after colliding with the elastic stretchable member. The embodiments of the present application do not limit this.

[0054] In some embodiments, the jig body 11 comprises a bearing surface 111 for bearing the reflective sheet 22. The elastic stretchable member is elastically stretchable and protrudes from the bearing surface 111.

[0055] Then, in the process of placing the reflective sheet 22 on the bearing surface 111, when the first positioning hole of the reflective sheet 22 is not aligned with the elastic stretchable member, the elastic stretchable member can be pressed by the reflective sheet 22 and be retracted into the jig body 11. When the first positioning hole of the reflective sheet 22 is aligned with the elastic stretchable member, the elastic stretchable member is restored and passes through the corresponding first positioning hole on the reflective sheet 22.

[0056] In some embodiments, the height of the elastic stretchable member protruding from the bearing surface 111 in the relaxed state is greater than the thickness of the reflective sheet 22. Alternatively, it can also be understood that the height of the elastic stretchable member protruding from the bearing surface 111 in the absence of external force is greater than the thickness of the reflective sheet 22.

[0057] Thus, the end of the elastic stretchable member away from the jig body 11 can pass through the first positioning hole on the reflective sheet 22, so as to improve the fixing effect of the elastic stretchable member on the reflective sheet 22.

[0058] In some embodiments, the lamp plate 21 can be provided with a second positioning hole corresponding to the elastic stretchable member, so that the elastic stretchable member can also be reused for positioning the lamp plate 21.

[0059] In some other embodiments, the lamp plate 21 can also not be provided with a second positioning hole corresponding to the elastic stretchable member. Then, in the process of pasting the lamp plate 21 to the reflective sheet 22 borne by the jig body 11, the end of the elastic stretchable member passing through the reflective sheet 22 can be pressed by the lamp plate 21 and be retracted into the jig body 11 to avoid position, so as to avoid damage of the lamp plate 21 after colliding with the elastic stretchable member.

[0060] The number of the first positioning components 12 can be one; the number of the first positioning components 12 can also be multiple, for example, two, three, four, five or even ten, and the embodiments of the present application do not limit this.

[0061] Then, when the number of the first positioning components 12 is multiple, multiple positions of the reflective sheet 22 can be positioned by the multiple first positioning components 12, so as to improve the position accuracy of the reflective sheet 22 placed on the jig body 11.

[0062] In some embodiments, the number of the first positioning components 12 is at least four, so that each corner of the outer periphery of the reflective sheet 22 can be positioned by at least one first positioning component 12.

[0063] For example, the reflective sheet 22 can be a rectangular sheet structure, and then the first positioning holes can be arranged at the four corners of the reflective sheet 22 respectively to match and position the different first positioning components 12, so that the whole reflective sheet 22 can be accurately carried on the jig body 11 in the appropriate position in the way that the four corners of the reflective sheet 22 are all positioned accurately, and then the subsequent lamp panel 21 can be conveniently and accurately bonded and fixed to the reflective sheet 22.

[0064] In some embodiments, the number of the first positioning components 12 is at least four, and all the first positioning components 12 are arranged at different corners of the jig body 11 respectively.

[0065] Then, compared with the middle part of the jig body 11, the first positioning components 12 are also arranged at the middle part of the jig body 11, which can not only ensure the accurate positioning of the reflective sheet 22, but also reduce the required first positioning components 12.

[0066] It can be understood that when the number of the first positioning components 12 is reduced, on the one hand, the manufacturing cost of the assembly jig 100 can be reduced, on the other hand, the reflective sheet 22 can be avoided to be difficult to place on the jig body 11 due to too many first positioning components 12, and on the other hand, the reflective sheet 22 does not need to be provided with too many first positioning holes, so that the reflective sheet 22 can cover a larger area of the light emitting side of the lamp panel 21 to improve the light output of the backlight module 200.

[0067] In some embodiments, the elastic telescopic member can include a glass bead screw. The jig body 11 is provided with a mounting hole 113 with an opening on the carrying surface 111, and the glass bead screw is screwed into the mounting hole 113, so that one end of the glass bead screw protrudes from the carrying surface 111.

[0068] The above is some introduction to the first positioning component 12 in the embodiments of the present application, and the technical solutions of the embodiments of the present application will be introduced below in combination with the second positioning component 13.

[0069] Please continue to refer to Figure 5 In some embodiments, the second positioning component 13 is arranged along the outer periphery of the jig body 11, and the second positioning component 13 protrudes from the side surface of the jig body 11 for carrying the reflective sheet 22 (i.e. the above-mentioned carrying surface 111) to cooperate with the outer peripheral side surface of the lamp panel 21 for positioning.

[0070] Thus, after the reflective sheet 22 is carried on the jig body 11, the second positioning component 13 abuts against the outer circumferential edge of the lamp plate 21 to realize positioning of the lamp plate 21 in the process of bonding the lamp plate 21 to the reflective sheet 22.

[0071] For example, the second positioning component 13 is arranged along the outer periphery of the jig body 11 to define a fitting space for accommodating at least part of the reflective sheet 22 and at least part of the lamp plate 21.

[0072] Correspondingly, the first positioning component 12 can be located at least partially in the fitting space.

[0073] The number of the second positioning component 13 can be one; the number of the second positioning component 13 can also be multiple, for example, two, three, four, five or even ten, and the embodiments of the present application do not limit this.

[0074] In some embodiments, the number of the second positioning component 13 is multiple, and the multiple second positioning components 13 are arranged at intervals along the outer periphery of the jig body 11.

[0075] It can be understood that if the second positioning component 13 is a closed ring structure surrounding the jig body 11, on the one hand, it will cause the manufacturing cost of the assembly jig 100 to rise, and on the other hand, it will also cause the problem of over-positioning due to the excessive positioning contact area between the second positioning component 13 and the lamp plate 21, ultimately leading to the difficulty of putting the lamp plate 21 into the inner circumferential side of the second positioning component 13, and when there is a certain manufacturing tolerance in the circumferential edge of the lamp plate 21, it is easy to be unable to put into the inner circumferential side of the second positioning component 13.

[0076] In some embodiments, the number of the second positioning component 13 is multiple, and the second positioning component 13 is arranged at the corner of the outer periphery of the jig body 11.

[0077] For example, the jig body 11 can be a rectangular plate structure, and then one second positioning component 13 can be arranged at each of the four corners of the jig body 11, so as to realize positioning of the four corners of the lamp plate 21, to ensure that the lamp plate 21 is accurately bonded and fixed to the reflective sheet 22.

[0078] The second positioning component and the jig body 11 can be integrally formed or separately formed, and the embodiments of the present application do not limit this.

[0079] Of course, in some other embodiments, the second positioning component 13 can also include a positioning column for penetrating the lamp plate 21 to position the lamp plate 21, and the embodiments of the present application do not limit this.

[0080] The above is some introduction to the first positioning component 12 in the embodiments of the present application. The technical solutions of the embodiments of the present application will be introduced below in combination with the jig body 11.

[0081] The jig body 11 can include a bearing surface 111 for bearing the reflective sheet 22. The jig body 11 further includes an avoiding hole 112, the aperture of which is formed on the bearing surface 111, and the avoiding hole 112 is used for accommodating the diffusion plate support 23 of the backlight module 200. Thus, after the reflective sheet 22 is borne on the bearing surface 111 of the jig body 11, one end of the diffusion plate support 23 can be first threaded through the reflective sheet 22 and accommodated in the avoiding hole 112, so as to realize the assembly of the diffusion plate support 23 and the reflective sheet 22.

[0082] It can be understood that the diffusion plate support 23 can be pre-welded and fixed to the lamp plate 21. Then, in the process of attaching the lamp plate 21 to the reflective sheet 22, the lamp plate 21 can drive the diffusion plate support 23 to be threaded through the reflective sheet 22.

[0083] Alternatively, the diffusion plate support 23 can be first threaded through the reflective sheet 22, and then the lamp plate 21 is attached to the reflective sheet 22, so that one end of the diffusion plate support 23 is clamped between the reflective sheet 22 and the lamp plate 21 to realize the fixation. The embodiments of the present application do not limit this.

[0084] Please continue to refer to Figure 6 In some embodiments, the assembly jig 100 further includes a light source assembly 14, which is arranged on the jig body 11 and is used to generate light rays directed to the avoiding hole 112 for indicating the position of the avoiding hole 112.

[0085] Then, it can be understood that a plurality of hole positions are usually formed on the reflective sheet 22 for the diffusion plate support 23 and the lamp beads of the lamp plate 21 to thread through. Therefore, when the reflective sheet 22 is borne on the jig body 11, it is usually difficult for the operator to determine from which position of the reflective sheet 22 the diffusion plate support 23 should be threaded through the reflective sheet 22 for installation. In the embodiments of the present application, the position of the avoiding hole 112 is indicated by the light source assembly 14, which can facilitate the operator to quickly install the diffusion plate support 23 to the correct position, thereby improving the assembly efficiency of the diffusion plate support 23.

[0086] In some embodiments, the light source assembly 14 can include a plurality of light emitting units, and each avoiding hole 112 is arranged in correspondence with at least one light emitting unit.

[0087] For example, the avoiding hole 112 can be a through hole penetrating through the jig body 11, and the light emitting unit can be arranged on the side of the jig body 11 away from the bearing surface 111.

[0088] In some embodiments, the jig body 11 comprises a resilient buffer 15 for carrying the reflecting sheet 22.

[0089] It can be understood that, after the reflecting sheet 22 is carried by the jig body 11, the lamp panel 21 can be pressed during the process of bonding the lamp panel 21 to the reflecting sheet 22 so that the lamp panel 21 is more firmly bonded to the reflecting sheet 22. During the process of pressing the lamp panel 21, the resilient buffer 15 can be deformed adaptively to avoid the lamp panel 21 and / or the reflecting sheet 22 from being damaged by pressing.

[0090] The resilient buffer 15 can comprise foam, elastic rubber, etc., which are not limited in the embodiments of the present application.

[0091] The above is some introduction to the assembly jig 100 of the embodiments of the present application.

[0092] Please continue to refer to Figure 7 The embodiments of the present application also provide an assembly method, which is applied to the above-mentioned assembly jig 100. The assembly method comprises:

[0093] 101. The reflecting sheet 22 is positioned by the first positioning component 12 to be placed on the jig body 11.

[0094] 102. The lamp panel 21 is positioned by the second positioning component 13 and pasted to the reflecting sheet 22 carried by the jig body 11.

[0095] Therefore, the embodiments of the present application can accurately paste the reflecting sheet 22 and the lamp panel 21, thereby improving the display effect of the display device.

[0096] Moreover, since the reflecting sheet 22 is carried by the jig body 11 and positioned by the first positioning component 12, the reflecting sheet 22 can be placed flat on the jig body 11, thereby avoiding the situation that the reflecting sheet 22 is wrinkled on the surface of the lamp panel 21 when the reflecting sheet 22 is manually pasted to the lamp panel 21, and further making the pasting of the reflecting sheet 22 not only have the advantages of easy operation and high operation efficiency, but also improve the pasting quality of the reflecting sheet 22 to improve the display effect of the display device.

[0097] Please continue to refer to Figure 8 According to the method described in the foregoing embodiments, the following will be further described in detail by way of example. The assembly method can comprise:

[0098] 201. The reflecting sheet 22 is positioned by the first positioning component 12 to be placed on the jig body 11.

[0099] In some embodiments, the reflective sheet 22 has an adhesive surface for bonding with the lamp panel 21, and the reflective sheet 22 is positioned by the first positioning component 12 to be placed to the jig body 11, comprising:

[0100] The reflective sheet 22 is obtained, the reflective sheet 22 comprises the reflective sheet 22 and the release paper bonded to the adhesive surface; the reflective sheet 22 is positioned by the first positioning component 12 to be placed to the jig body 11, so that the side surface of the reflective sheet 22 away from the release paper is carried on the jig body 11; the release paper of the reflective sheet 22 carried by the jig body 11 is peeled off from the adhesive surface.

[0101] 202, the diffusion plate support 23 is passed through the reflective sheet 22 carried by the jig body 11.

[0102] 203, the lamp panel 21 is positioned by the second positioning component 13 and pasted to the reflective sheet 22 carried by the jig body 11, so that one end of the diffusion plate support 23 is clamped and fixed between the reflective sheet 22 and the lamp panel 21.

[0103] It can be understood that in the embodiments of the present application, the diffusion plate support 23 can be not pre-welded and fixed on the lamp panel 21, so that the welding step of welding the diffusion plate support 23 on the lamp panel 21 and the corresponding welding cost can be reduced, and the backlight module 200 is more suitable for batch production.

[0104] In the description of the present application, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
