Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of light guide plate production equipment, more particularly to a light guide plate side edge reflector pasting device. BACKGROUND

[0002] The four side edges of the light guide plate are usually provided with reflectors, which are used to re-emit the light from the inside of the light guide plate to the large side of the light guide plate, thereby improving the utilization rate of light and avoiding the leakage of light from the side of the light guide plate, which affects the overall lighting effect.

[0003] In the past, the attachment of reflectors was mostly done manually, but the efficiency was low and the attachment quality was not consistent. Therefore, some manufacturers designed auxiliary tools for attachment, such as the patent with publication number CN205103428U, which disclosed a device for attaching reflectors to the edge of the end face of a light guide plate. The device can vertically clamp multiple light guide plates together at one time, and then use a release paper with multiple reflective strips to align and attach the side edges. This can attach multiple reflectors to multiple corresponding light guide plates at one time, achieving batch attachment operation and improving efficiency and attachment quality.

[0004] However, the attachment process still requires manual operation to align the reflective strips, and the attachment error cannot be guaranteed. Once an error occurs, the clamped light guide plates need to be completely reworked, which will greatly affect the efficiency. UTILITY MODEL CONTENT

[0012] Furthermore, the positioning plate is provided with a groove, the upper side of which extends to the top surface of the positioning plate, forming a boss on the top surface of the positioning plate with an edge smaller than the edge of the positioning plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the light guide plate is placed on the positioning plate in the first positioning groove, and the side of the light guide plate is in contact with the inner wall of the first positioning groove.

[0021] Reference Figures 1 to 4 The present invention will be further described below.

[0022] A device for attaching a side reflector to a light guide plate includes a base 1. The base 1 has a first positioning groove 2, which is used to place a light guide plate 3. A liftable positioning plate 4 is disposed in the first positioning groove 2. Attachment blocks 5 are disposed around the perimeter of the positioning plate 4. A second positioning groove 6 is disposed on the attachment block 5, which is used to place a reflector 7. The second positioning groove 6 is rotatably and slidably connected to the base 1. A lifting drive mechanism is disposed on the positioning plate 4. A translation mechanism is disposed between the attachment block 5 and the base 1. A rotation mechanism is disposed between the attachment block 5 and the translation mechanism.

[0023] like Figures 1 to 4 As shown, the attachment process is as follows:

[0024] The positioning plate 4 is lowered by the lifting drive mechanism, exposing the first positioning groove 2. The light guide plate 3 is placed into the first positioning groove 2, and the side of the light guide plate 3 is in contact with the inner wall of the first positioning groove 2. The second positioning groove 6 on the attachment block 5 is vertically upward. The reflector 7 is placed into the second positioning groove 6. The adhesive release paper on the reflector 7 is peeled off or glue is applied to the reflector 7 to complete the preparation work.

[0025] The positioning plate 4 rises under the drive of the lifting mechanism, so that the light guide plate 3 extends completely out of the first positioning groove 2. Then the attachment block 5 rotates 90 degrees so that the adhesive surface of the reflective sheet 7 faces the light guide plate 3. The translation mechanism then immediately drives the attachment block 5 to move towards the light guide plate 3, attaching the reflective sheet 7 to the side of the light guide plate 3, thus completing the attachment of the reflective sheet 7. The attachment is automated, efficient, and the light guide plate 3 and reflective sheet 7 are accurately positioned, resulting in good attachment quality.

[0026] Specifically, during the attachment process, two opposing attachment blocks 5 are attached simultaneously, then the attachment blocks 5 are reset, and then the other two opposing attachment blocks 5 are attached, so that the light guide plate 3 is not pushed during the attachment process.

[0027] like Figure 1 and Figure 3 As shown in the preferred embodiment, the lifting drive mechanism includes a lifting bracket 8, a screw nut 9 fixed on the lifting bracket 8, a screw rod 10 rotatably connected to the base 1, the screw nut 9 and the screw rod 10 being threadedly connected, the positioning plate 4 being connected to the lifting bracket 8, and a drive motor 11 being connected to the screw rod 10.

[0028] Specifically, when the drive motor 11 drives the lead screw 10 to rotate, it can drive the lifting bracket 8 to rise and fall through the lead screw nut 9, and thus drive the positioning plate 4 to rise and fall.

[0029] like Figure 1 As shown in this embodiment, preferably, the base 1 is provided with a guide rod 12, which passes through the lifting bracket 8. The lifting bracket 8 is slidably connected to the guide rod 12 to improve the lifting stability of the lifting bracket 8.

[0030] like Figure 1 As shown in this embodiment, preferably, a guide rail 13 is provided on the inner wall of the first positioning groove 2, and a guide groove corresponding to the guide rail 13 is provided on the positioning plate 4 to improve the lifting stability of the positioning plate 4.

[0031] like Figure 1 As shown in the preferred embodiment, the translation mechanism includes a translation block 14 slidably connected to the base 1, the rotation mechanism is located on the translation block 14, and the first cylinder 15 is connected to the translation block 14.

[0032] Specifically, the piston rod of the first cylinder 15 extends, which drives the translation block 14 to move on the base 1, and drives the attachment block 5 to move toward the guide light plate 3.

[0033] like Figure 1 and Figure 4 As shown in the preferred embodiment, the rotating mechanism includes a support block 16, the attachment block 5 is rotatably connected to the support block 16, the attachment block 5 is provided with a hinged drive rod 17, the drive rod 17 is connected to a second cylinder 18, and the piston rod of the second cylinder 18 is hinged to the drive rod 17.

[0034] Specifically, when the piston rod of the second cylinder 18 extends or retracts, the attachment block 5 rotates on the support block 16 through the linkage of the drive rod 17. That is, when the piston rod of the second cylinder 18 extends, the attachment block 5 is horizontal and the second positioning groove 6 faces the guide light plate 3. When the piston rod of the second cylinder 18 retracts, the attachment block 5 is vertical and the second positioning groove 6 faces upward.

[0035] like Figure 4 As shown, in this preferred embodiment, the positioning plate 4 is provided with a groove 19, the upper side of the groove 19 extends to the top surface of the positioning plate 4, and a boss 20 with an edge smaller than the edge of the positioning plate 4 is formed on the top surface of the positioning plate 4.

[0036] When the attaching block 5 moves to attach the reflective sheet 7 to the light guide plate 3, the attaching block 5 can apply a certain amount of pressure to the reflective sheet 7, so that the adhesive surface on the reflective sheet 7 can be more effectively attached to the light guide plate 3.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
