In this way, a suitable support base can be replaced according to the outer contour of the backlight module to better fix the backlight module.

[0008] In one embodiment, the adsorption seat is magnetically connected to the base. Since the adsorption seat is magnetically connected to the base, it is convenient to adjust the position of the adsorption seat on the base as needed, thereby better adsorbing and fixing the backlight module on the top of the base, which is convenient for subsequent bonding operations on the backlight module.

[0011] In one embodiment, the base is provided with a plurality of spacing parts corresponding to the plurality of positioning parts; two adjacent positioning parts are separated by the corresponding spacing parts.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0023] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0025] During the production process of LCD screens, the backlight module needs to be fixed so that it can be assembled with other components (such as LCD screen modules). However, the traditional backlight module positioning fixture is usually suitable for the bonding of backlight modules of a single size. If backlight modules of different sizes are required, the corresponding positioning fixture needs to be replaced, which increases the cost of the fixture and requires the disassembly and assembly of the fixture, which increases the time and difficulty of machine adjustment. Therefore, the traditional backlight module positioning fixture has poor versatility.

[0026] In order to solve the problem of poor versatility of traditional backlight module positioning jigs, the present application provides a backlight module positioning jig that can be used to position backlight modules of different sizes and meet the fitting requirements of backlight modules of different sizes. It can reduce the cost of the jig to a certain extent, reduce the time and difficulty of adjustment, and improve the versatility of the positioning jig.

[0027] Figure 1 FIG. 1 shows a schematic structural diagram of a backlight module positioning fixture in an embodiment of the present application. Figure 2 FIG. 1 shows a top view of a backlight module positioning fixture in an embodiment of the present application. Figure 3 A side view of a backlight module positioning fixture in an embodiment of the present application is shown.

[0028] See also Figure 1-Figure 3 An embodiment of the present application provides a backlight module positioning fixture 10 , including a base 100 , a plurality of supporting seats 200 and a plurality of adsorption seats 310 .

[0029] The supporting seat 200 is movably disposed on the top of the base 100, and multiple supporting seats 200 are used to support the backlight module. The position of the supporting seat 200 can be moved according to the size of the backlight module, so that the multiple supporting seats 200 can well support the backlight module.

[0030] The adsorption seat 310 and the supporting seat 200 are arranged at a distance on the top of the base 100 , and the adsorption seat 310 is movably arranged on the top of the base 100 . The adsorption seat 310 is used to adsorb the backlight module on the supporting seat 200 .

[0031] In this way, when the backlight module positioning jig 10 is used, the backlight module is placed on multiple supporting seats 200, and the multiple supporting seats 200 are used to jointly support the backlight module, and the position of the adsorption seat 310 is moved, so that the multiple adsorption seats 310 can be used to jointly adsorb the backlight modules on the multiple supporting seats 200, so that the backlight module can be positioned on the backlight module positioning jig 10, and the position of the supporting seat 200 can be adjusted according to the size of the backlight module. Therefore, the backlight module positioning jig 10 can be used to position backlight modules of different sizes and meet the bonding operation requirements of backlight modules of different sizes. To a certain extent, it can reduce the cost of the jig, reduce the time and difficulty of adjustment, and improve the versatility of the positioning jig.

[0032] In some embodiments, the support base 200 is magnetically connected to the base 100 .

[0033] The base 100 may include a magnetic material and the support base 200 may include a metal material; or the base 100 may include a metal material and the support base 200 may include a magnetic material. In this way, it is convenient to adjust the position of the support base 200 on the base 100 as needed, and to move the support base 200 to a desired position according to the size of the backlight module, thereby better utilizing multiple support bases 200 to support the backlight module.

[0034] In some embodiments, the support base 200 includes a magnetic base body 210 and a support base body 220 for supporting the backlight module. The magnetic base body 210 is magnetically connected to the base 100, and the support base body 220 is detachably connected to the side of the magnetic base body 210 away from the base 100.

[0035] Optionally, the magnetic base 210 is made of magnetic material, and the base 100 is made of metal material.

[0036] Optionally, the bearing seat body 220 is detachably connected to a side of the magnetic seat body 210 facing away from the base 100 by bolts.

[0037] In this way, a suitable supporting base 220 can be replaced according to the outer contour of the backlight module to better fix the backlight module.

[0038] Specifically, the support base 220 is provided with a limiting groove C for limiting the movement of the backlight module on the support base 220 along the first direction F1 and / or the second direction F2. The first direction F1 and the second direction F2 are perpendicular to each other and parallel to the bottom surface of the base 100.

[0039] Optionally, the supporting seat 220 includes a supporting bottom wall 221 for supporting the backlight module, and at least one limiting side wall 222, the supporting bottom wall 221 and at least one limiting side wall 222 define a limiting groove C, and the limiting side wall 222 is used to limit the movement of the backlight module on the supporting seat 220 along the first direction F1 and / or the second direction F2.

[0040] For example, the limiting groove C is L-shaped, for example, one limiting side wall 222 is provided, and the bearing bottom wall 221 and the limiting side wall 222 are vertically arranged to form an L-shaped limiting groove C; for another example, one limiting side wall 222 is provided with two limiting side walls, and the bearing bottom wall 221 and the two limiting side walls 222 are perpendicular to each other to form an L-shaped limiting groove C. For distinguishing explanation, the plurality of bearing seats 220 include a first bearing seat 220a and a second bearing seat 220b, the first bearing seat 220a includes a bearing bottom wall 221 and two limiting side walls 222, and the two limiting side walls 222 are used to limit the movement of the backlight module on the bearing seat 220 along the first direction F1 and the second direction F2 respectively. The second bearing seat 220b includes a bearing bottom wall 221 and a limiting side wall 222.

[0041] In this way, two first bearing seats 220a can be arranged at two diagonal points of the backlight module, and then the bearing bottom walls 221 of the two first bearing seats 220a can be used to support the two diagonal points of the backlight module, and the two limiting side walls 222 of each first bearing seat 220a can respectively limit the movement of the backlight module along the first direction F1 and the second direction F2, and the two second bearing seats 220b can also be arranged oppositely and spaced apart along the first direction F1 or the second direction F2, so that the backlight module can be limited between the two second bearing seats 220b. For example, four second bearing seats 220b are provided, and the four second bearing seats 220b are divided into two groups, each group is provided with two second bearing seats 220b arranged oppositely and spaced apart along the second direction F2. In this way, the backlight module can be well fixed above the base 100, so as to facilitate the subsequent bonding operation of the backlight module.

[0042] In some embodiments, the adsorption seat 310 is magnetically connected to the base 100 .

[0043] It can be that the adsorption seat 310 includes a suction cup seat (not shown in the figure) that can be magnetically connected to the base 100, and a suction cup (not shown in the figure) arranged on the suction cup seat, and the adsorption cup is connected to the vacuum adsorption device. In this way, the vacuum adsorption device can be used to form a negative pressure on the adsorption cup, thereby adsorbing the backlight module.

[0044] Of course, in other embodiments, the adsorption seat 310 may be an integral body, and a adsorption hole for adsorbing the backlight module may be provided on the adsorption seat 310. A suction tube 320 connected to the adsorption hole may be provided on the side wall of the adsorption seat 310, and one end of the suction tube 320 away from the adsorption hole is connected to the vacuum adsorption device. In this way, the vacuum adsorption device may be used to form a negative pressure on the adsorption hole on the adsorption seat 310, thereby adsorbing the backlight module.

[0045] Specifically, the ends of the suction tubes 320 on the multiple adsorption seats 310 away from the adsorption holes are connected to a connecting head 330, so that the suction tubes 320 on the multiple adsorption seats 310 are connected to the vacuum adsorption device through the connecting head 330, which facilitates the formation of negative pressure on the adsorption holes of the multiple adsorption seats 310 through the vacuum adsorption device, thereby facilitating the adsorption of the backlight module.

[0046] Since the adsorption seat 310 is magnetically connected to the base 100, it is convenient to adjust the position of the adsorption seat 310 on the base 100 as needed, so as to better adsorb and fix the backlight module on the top of the base 100, which is convenient for subsequent bonding operations on the backlight module.

[0047] In some embodiments, a plurality of positioning portions 110 are disposed on the base 100 . The positioning portions 110 correspond to the supporting seats 200 one by one. The supporting seats 200 are detachably disposed on the tops of the corresponding positioning portions 110 .

[0048] Alternatively, the support base 200 may be magnetically connected to the corresponding positioning portion 110 .

[0049] Of course, in other embodiments, the support base 200 may also be engaged with the corresponding positioning portion 110 to move the support base 200. For example, the positioning portion 110 is configured as a slot, and the bottom of the support base 200 is engaged in the slot.

[0050] Since the supporting seat 200 is detachably arranged on the top of the corresponding positioning portion 110, it is convenient to move the supporting seat 200 according to the size of the backlight module. The supporting seat 200 can be moved from the top of one positioning portion 110 to the top of another positioning portion 110, so that multiple supporting seats 200 can be arbitrarily combined to be suitable for supporting backlight modules of corresponding sizes.

[0051] In some embodiments, the positioning portion 110 has a positioning surface 111 , and the positioning surface 111 has the same shape as the bottom surface of the corresponding supporting seat 200 .

[0052] It can be understood that the positioning surface 111 and the bottom surface of the corresponding supporting seat 200 have substantially the same shape, and can be circular, square or other shapes.

[0053] In this way, it is convenient to align the bottom surface of the supporting seat 200 with the center of the positioning surface 111 of the corresponding positioning portion 110, so as to more accurately position the supporting seat 200 on the corresponding positioning portion 110, thereby facilitating the adjustment of the position of the supporting seat 200 according to the size of the backlight module, thereby improving the positioning accuracy of the backlight module.

[0054] In the present embodiment, the positioning surface 111 is configured as a square.

[0055] In this way, the supporting base 200 can be more accurately aligned with the corresponding positioning portion 110 , thereby improving the positioning accuracy of the backlight module.

[0056] In this embodiment, a plurality of spacing portions 120 corresponding to the plurality of positioning portions 110 are disposed on the base 100 , and adjacent positioning portions 110 are spaced apart by the corresponding spacing portions 120 .

[0057] Specifically, the plurality of spacers 120 are connected in a mesh shape, which is beneficial to reducing the number of the spacers 120 and further reducing the occupied size of the base 100 .

[0058] Since adjacent positioning portions 110 are separated by corresponding spacing portions 120 , it is convenient to clearly distinguish different positioning portions 110 , and to place the support base 200 on the top of the corresponding positioning portion 110 , thereby improving the positioning accuracy of the backlight module.

[0059] In some embodiments, coordinate information 130 is provided on the plurality of positioning portions 110 .

[0060] In this way, it is convenient to quickly confirm the size of the backlight module according to the coordinate information 130 , and then quickly move the support base 200 to the top of a suitable positioning portion 110 , which is beneficial to improving the positioning accuracy of the backlight module.

[0061] In this embodiment, the plurality of positioning portions 110 are arranged in rows and columns, and the plurality of positioning portions 110 are numbered sequentially to form coordinate information 130 .

[0062] Specifically, the plurality of positioning portions 110 are arranged in a checkerboard design, so that the coordinate information 130 can be easily obtained based on the plurality of positioning portions 110 .

[0063] In this way, a coordinate system can be constructed according to the continuous numbers on the plurality of positioning parts 110 to obtain the coordinate information 130 , which facilitates the quick confirmation of the size of the backlight module according to the coordinate information 130 and the quick movement of the supporting seat 200 to the top of a suitable positioning part 110 .

[0064] In some embodiments, the number of the supporting bases 200 is an even number.

[0065] For example, the number of the supporting seats 200 may be 4, 6, or 8, etc. In this embodiment, the number of the supporting seats 200 is 6.

[0066] In this way, it is convenient to distribute an even number of supporting seats 200 in a roughly symmetrical manner (which can be combined with Figure 2 To understand), an even number of supporting seats 200 can be used to roughly evenly distribute the gravity of the backlight module, thereby better utilizing an even number of supporting seats 200 to support the backlight module.

[0067] In some embodiments, the number of adsorption seats 310 is an even number.

[0068] For example, the number of adsorption seats 310 may be 2, 4, 6, or 8, etc. In this embodiment, the number of adsorption seats 310 is 2.

[0069] In this way, it is convenient to distribute the even number of adsorption seats 310 roughly symmetrically (which can be combined with Figure 2 To understand), the adsorption force applied by an even number of adsorption seats 310 to the backlight module is evenly distributed, and the even number of adsorption seats 310 can be used to better adsorb the backlight module.

[0070] When the backlight module positioning jig 10 of the present application is used, the coordinate information 130 can be used to quickly confirm the size of the backlight module, and then the support seat 200 can be quickly moved to the top of the appropriate positioning portion 110, and then multiple adsorption seats 310 are used to jointly adsorb the backlight modules on multiple support seats 200, so that the backlight module can be positioned on the backlight module positioning jig 10, so that the backlight module on the backlight module positioning jig 10 and the liquid crystal screen module (FOG for short) can be bonded together. In this way, the backlight module positioning jig 10 can be used to accurately position backlight modules of different sizes, meet the bonding operation requirements of backlight modules of different sizes, reduce the cost of the jig to a certain extent, reduce the time and difficulty of adjusting the machine, and improve the versatility of the positioning jig.

[0071] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
