[0034] The utility model discloses an assembly fixture for a light guide cover, which can keep the relative positions of a plurality of light guide plates unchanged during the assembly process, has high bonding accuracy, high assembly precision of the light guide cover, and better light guide homogenization effect.

[0035] Please also read Figure 1 to Figure 2 , is a structural schematic diagram of an assembly fixture 100 of a light guide cover provided by an embodiment of the utility model, the assembly fixture 100 includes a base 10 and a plurality of positioning members 11, each positioning member 11 includes a connecting portion 111 and a supporting portion 112, the connecting portion 111 is arranged on the base 10, the supporting portion 112 is arranged on the connecting portion 111, the supporting portion 112 is arranged at an angle to the base 10, and the supporting portions 112 of the plurality of positioning members 11 are arranged at intervals around a first straight line β perpendicular to the base 10, and each supporting portion 112 is used to support the light guide plate a (such as Figure 3 as shown).

[0036] In this embodiment, the base 10 is used to set the connecting parts 111 of the plurality of positioning members 11, and the supporting parts 112 of the positioning members 11 are arranged at an angle with the base 10, and each supporting part 112 can be used to support the light guide plate a. At the same time, the supporting parts 112 of the plurality of positioning members 11 surround the first straight line β perpendicular to the base 10, so that when the plurality of light guide plates a are supported on the supporting parts 112 of the plurality of positioning members 11 respectively, the plurality of light guide plates a can be in an enclosed shape for easy bonding. Based on this, the supporting parts 112 of the plurality of positioning members 11 are used to support the light guide plate a, and the supporting parts 112 are used to position the light guide plate a, so that the plurality of light guide plates a can maintain the relative positions of the enclosure unchanged during the assembly process, the bonding accuracy is high, the assembly accuracy of the light guide cover is high, and the light guide homogenization effect is better.

[0037] Specifically, when assembling the light guide cover, multiple light guide plates a are respectively supported on the supporting parts 112 of multiple positioning members 11, and multiple light guide plates a are in a state of enclosing the first straight line β, and the adjacent edges of two adjacent light guide plates a are in contact with each other, and then glue is applied to the adjacent edges of two adjacent light guide plates a so that the two adjacent light guide plates a are bonded and fixed. Among them, UV (Ultraviolet) glue can be used to fix the two ends of the adjacent edges of the two adjacent light guide plates a, and cured by UV lamp, and silicone glue can be used to fix the middle of the adjacent edges of the two adjacent light guide plates a, and cured by baking (for example, baking in an oven or baking lamp).

[0038] In this embodiment, if Figure 2 As shown, the base 10 is provided with a through slot 10a that passes through two opposite sides of the base 10, the connecting portion 111 is provided at one side of the base 10, and the supporting portion 112 extends from the connecting portion 111 and passes through the through slot 10a, and protrudes to the side of the base 10 away from the connecting portion 111, and is inclined to the first straight line β. In this way, on the one hand, by providing the connecting portion 111 at one side of the base 10, the supporting portion 112 extends from the connecting portion 111 and protrudes to the side of the base 10 away from the connecting portion 111, a larger surface area can be formed for supporting the light guide plate a, thereby improving the stability of positioning, and the supporting portion 112 is inclined to the first straight line β so that the supporting portion 112 and the base 10 can be arranged at an angle. On the other hand, by using the through groove 10a to guide the supporting part 112 for installation, the installation accuracy of the positioning member 11 and the base 10 can be improved, and the accuracy of the angle α between the supporting part 112 and the base 10 can be ensured, thereby improving the assembly accuracy of the light guide hood assembled by the assembly fixture 100, and the yield rate of the light guide hood is relatively high.

[0039] In some other embodiments, the connection portion 111 is disposed on one side of the base 10, and the supporting portion 112 extends from the connection portion 111 in a direction away from the base 10 and is inclined to the first straight line β. In this way, by disposing the connection portion 111 on the base 10, the supporting portion 112 extends in a direction away from the base 10 to form a larger surface area for supporting the light guide plate a, thereby improving the positioning stability, and the supporting portion 112 is inclined to the first straight line β so that the supporting portion 112 and the base 10 can be arranged at an angle.

[0040] In some embodiments, such as Figure 4 and Figure 5 As shown, the base 10 is provided with a plurality of overflow glue grooves 10d, each overflow glue groove 10d is provided through two opposite sides of the base 10, and each overflow glue groove 10d is distributed between two adjacent supporting parts 112. In this way, by providing a plurality of overflow glue grooves 10d, when two adjacent light guide plates a are bonded, excess glue flows toward the base 10 along the adjacent edges of the two light guide plates a. At this time, the overflow glue groove 10d can receive the excess glue and overflow to the side of the base 10 away from the light guide plate a.

[0041] Exemplarily, the length of the cross section of the overflow glue groove 10d is L, the width is t, 4mm≤L≤10mm, 4mm≤t≤10mm. Taking the length L of the cross section of the overflow glue groove 10d as an example, if the length L is less than 4mm, the dimension of the cross section in the length direction is small, the overall area of ​​the cross section is small, the speed at which the excess glue overflows from the overflow glue groove 10d is slow, and the overflow effect of the overflow glue groove 10d is poor. If the length L is greater than 10mm, the dimension of the cross section in the length direction is large, the overall area of ​​the cross section is large, and when the overflow speed of the glue is met, the hollow volume of the base 10 at the overflow glue groove 10d is large, and the overall strength of the base 10 is low. Therefore, the length L of the cross section of the overflow glue groove 10d can be 4mm≤L≤10mm, the cross-sectional area of ​​the overflow glue groove 10d is moderate, the excess glue can overflow from the overflow glue groove 10d in time, and the overall strength of the base 10 is high. Furthermore, the length L of the cross section of the glue overflow groove 10d may be 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc., which is not specifically limited in this embodiment.

[0042] Similarly, the width t of the cross section of the overflow glue groove 10d can be 4mm≤t≤10mm, the cross section area of ​​the overflow glue groove 10d is moderate, the excess glue can overflow through the overflow glue groove 10d in time, and the overall strength of the base 10 is high. In addition, the width t of the cross section of the overflow glue groove 10d can be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc., which is not specifically limited in this embodiment.

[0043] In some embodiments, the base 10 is provided with a plurality of positioning grooves 10e, and the plurality of positioning grooves 10e are arranged around the first straight line β, and each positioning groove 10e is used to abut against the light guide plate a supported on the supporting portion 112. In this way, by providing a plurality of positioning grooves 10e on the base 10, when the light guide plate a is supported on the supporting portion 112, the light guide plate a can abut against the positioning grooves 10e, so that the positioning grooves 10e and the supporting portion 112 are used to perform dual positioning on the light guide plate a, thereby improving the position stability of the light guide plate a on the assembly jig 100, so that the plurality of light guide plates a can maintain the relative positions of the enclosure unchanged during the assembly process, the bonding accuracy is high, the assembly accuracy of the light guide cover is high, and the light guide homogenization effect is better.

[0044] Exemplarily, both ends of each positioning groove 10e extend to the edge of the base 10, and multiple positioning grooves 10e are arranged crosswise in pairs. In this way, by extending both ends of the positioning groove 10e to the edge of the base 10, the extension length of the positioning groove 10e is large, which can match light guide plates a of different sizes, and make the adjacent edges of two adjacent light guide plates a butt against each other at the intersection of the two adjacent positioning grooves 10e, so as to facilitate bonding of the adjacent edges of the two adjacent light guide plates a.

[0045] Optionally, a glue overflow groove 10d is provided at the intersection of two adjacent positioning grooves 10e. In this way, by making the adjacent edges of two adjacent light guide plates a butt against each other at the intersection of two adjacent positioning grooves 10e, when the adjacent edges of the two adjacent light guide plates a are bonded, when the excess glue flows along the adjacent edges of the two light guide plates a toward the base 10, the excess glue can just flow to the glue overflow groove 10d located at the intersection of the two adjacent positioning grooves 10e, thereby preventing the excess glue from spreading to other positions of the base 10.

[0046] Alternatively, if Figure 6 As shown, the angle between the supporting portion 112 and the base 10 is α, 30°≤α≤90°. In this way, different angles α are selected according to the different inclination angles of the light guide plate a of the light guide hood to be assembled by the assembly jig 100 relative to the central axis of the light guide hood, so that the assembly jig 100 can be applied to the assembly of light guide hoods of different specifications, and has a wide range of applications. In addition, the angle α between the supporting portion 112 and the base 10 can be 30°, 45°, 60°, 75°, 90°, etc., and this embodiment does not make specific limitations on this.

[0047] In some embodiments, the base 10 is provided with a receiving groove 10c, and the connecting portion 111 is provided in the receiving groove 10c. In this way, by accommodating the connecting portion 111 in the receiving groove 10c, the space occupied by the connecting portion 111 can be reduced, thereby reducing the overall volume of the assembly jig 100, which is conducive to the miniaturized design of the assembly jig 100 and is suitable for the mass production of light guide covers.

[0048] As an optional embodiment, the base 10 is provided with a plurality of receiving grooves 10c, and the plurality of receiving grooves 10c are arranged at intervals around the first straight line β, and the connecting portions 111 of the plurality of positioning members 11 are respectively arranged in the plurality of receiving grooves 10c. In this way, the space occupied by the connecting portions 111 can be reduced by accommodating the plurality of connecting portions 111 one by one through the plurality of receiving grooves 10c, and the plurality of receiving grooves 10c are arranged at intervals around the first straight line β, so that the plurality of supporting portions 112 can be arranged at intervals around the first straight line β.

[0049] As another optional embodiment, the receiving groove 10c is extended around the first straight line β, and the connecting portions 111 of the plurality of positioning members 11 are arranged at intervals in the receiving groove 10c. In this way, the space occupied by the connecting portions 111 can be reduced by accommodating the plurality of connecting portions 111 in the receiving groove 10c, and the receiving groove 10c is extended around the first straight line β, and the connecting portions 111 of the plurality of positioning members 11 are arranged at intervals in the receiving groove 10c, so that the plurality of supporting portions 112 can be arranged at intervals around the first straight line β.

[0050] In some embodiments, such as Figure 2 and Figure 7 As shown, the connecting portion 111 is detachably arranged on the base 10. In this way, the connecting portion 111 and the base 10 are detachably arranged, so that the positioning member 11 and the base 10 can be disassembled and assembled, so that different specifications of the positioning members 11 can be replaced according to different assembly requirements to assemble different specifications of light guide covers.

[0051] Exemplarily, the connecting portion 111 is provided with a through hole 111a, the base 10 is provided with a connecting hole 10b, and the assembly jig 100 further includes a fastener 12, which passes through the through hole 111a and is detachably connected to the connecting hole 10b, so as to press the connecting portion 111 against the base 10. In this way, by passing the fastener 12 through the through hole 111a and being detachably connected to the connecting hole 10b, the connecting portion 111 can be pressed against the base 10, thereby achieving the fixation of the connecting portion 111 and the base 10. When the fastener 12 is detached from the connecting hole 10b, the connecting portion 111 and the base 10 can be separated, thereby achieving the disassembly of the connecting portion 111 and the base 10.

[0052] Optionally, the fastener 12 may be a bolt, a screw, etc., which is not specifically limited in this embodiment.

[0053] In some other embodiments, the detachable connection method between the connecting portion 111 and the base 10 includes but is not limited to a bayonet connection, a magnetic connection, a button connection, etc., which is not specifically limited in this embodiment.

[0054] The embodiment of the utility model provides an assembly jig 100 for a light guide cover, in which a plurality of connecting parts 111 of positioning members 11 are provided through a base 10, and a supporting part 112 of the positioning members 11 is arranged at an angle with the base 10, and each supporting part 112 can be used to support a light guide plate a.
