Description

Technical Field

[0001] This utility model relates to the field of optical sheets, and in particular to a jig for side-mounting multiple-piece optical sheets. Background Technology

[0002] Optical sheets such as light guide plates and diffuser plates are key technology products in the field of optics. The former achieves uniform light distribution through dot matrix design, while the latter softens light and eliminates glare using special optical formulas, and is widely used in backlight modules and other fields. In narrow bezel and splicing screen designs, to prevent light leakage from the sides and resulting in uneven display, reflective strips are usually attached to one or three sides of the light guide plate and four sides of the diffuser plate. However, existing side-attaching fixtures are inefficient, only able to attach one side at a time, severely limiting production efficiency.

[0003] Therefore, existing technologies urgently need to be addressed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a multi-piece side-mounting fixture for optical sheets. Based on the aforementioned problems, this invention provides a multi-piece side-mounting fixture for optical sheets that significantly increases production capacity and reduces production costs by simultaneously attaching multiple side-mounted light guide plates to the sides.

[0005] The technical solution of this utility model is implemented as follows: A jig for side-mounting multiple optical sheets includes a frame, an air-bearing platform, a transverse baffle for restricting the long-side displacement of multiple optical sheets, and a longitudinal baffle for restricting the wide-side displacement of multiple optical sheets. The transverse direction is defined as extending along the length direction of the frame, and the longitudinal direction is defined as extending along the width direction of the frame. The air-bearing platform is disposed above the frame, the transverse baffle is disposed on the outer side of the frame in the transverse direction, and the longitudinal baffle is disposed on the outer side of the frame in the longitudinal direction.

[0006] As described above, in the multi-piece mounting fixture for side-mounting optical sheets, the transverse baffle is fixedly disposed in the transverse direction outside the frame.

[0007] As described above, in the multi-piece mounting fixture for side-mounting optical sheets, the longitudinal baffle is vertically and flexibly positioned in the longitudinal direction outside the frame.

[0008] The multi-piece mounting fixture for side-mounting optical sheets described above also includes a pneumatic valve switch, which is electrically connected to a longitudinal baffle and can control the longitudinal baffle to rise or fall.

[0009] The multi-piece mounting fixture for side-mounting optical sheets as described above also includes an air-blowing switch, which enables the optical sheets to be suspended or adsorbed onto the air-floating platform.

[0010] The multi-piece mounting fixture for side-mounting optical sheets as described above further includes a U-shaped groove (7) for accommodating the side-mounting, the U-shaped groove being located opposite the transverse baffle and disposed below the frame, or / and the U-shaped groove being located opposite the longitudinal baffle and disposed below the frame.

[0011] As described above, the multi-piece mounting fixture for side-mounting optical sheets consists of at least two side-mounting strips forming a group.

[0012] The optical sheet is a light guide plate or a diffuser plate, as described above, for side-mounting multi-piece mounting fixtures for optical sheets.

[0013] The multi-piece mounting fixture for side-mounting optical sheets, as described above, also includes casters located at the four lower corners of the frame.

[0014] As described above, in the multi-piece mounting fixture for side-mounting optical sheets, the longitudinal baffle is located at one-third of the left side of the frame.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. This utility model provides a multi-piece mounting fixture for side-mounting optical sheets. Through horizontal and vertical baffles, it achieves precise positioning of the optical sheets and alignment of their long and wide sides. The air-floating platform uses airflow to suspend the optical sheets, facilitating fine-tuning alignment and frictionless movement. Combined with the mechanical limiting of the horizontal and vertical baffles, it ensures that multiple optical sheets simultaneously achieve a high degree of positional consistency, laying the foundation for high-quality subsequent side-mounting.

[0016] 2. This utility model provides a multi-sided mounting fixture for side-mounting optical sheets, which can perform multi-sided mounting of multiple optical sheets at one time, completely changing the inefficient mode of traditional single-sheet single-sided mounting. Through batch operation, production efficiency is improved. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 As shown, a multi-piece mounting fixture for side-mounting optical sheets includes a frame 1, an air-floating platform 4, a transverse baffle 2 restricting the long-side displacement of multiple optical sheets 8, and a longitudinal baffle 3 restricting the wide-side displacement of the multiple optical sheets 8. The transverse direction is defined as extending along the length of the frame 1, and the longitudinal direction is defined as extending along the width of the frame 1. The air-floating platform 4 is positioned above the frame 1, the transverse baffle 2 is positioned on the outer side of the frame 1 in the transverse direction, and the longitudinal baffle 3 is positioned on the outer side of the frame 1 in the longitudinal direction. Preferably, the multiple optical sheets 8 in this application are at least two optical sheets 8. Optionally, the multiple optical sheets 8 are two sheets; optionally, the multiple optical sheets 8 are five sheets; optionally, the multiple optical sheets 8 are fifteen sheets. Most preferably, the multiple optical sheets 8 are ten sheets. The number of optical sheets 8 is the same as the number of side-mounting 9.

[0023] Preferably, the transverse baffle 2 is fixedly disposed in the transverse direction on the outside of the frame 1. Preferably, there are two transverse baffles 2. The transverse baffles 2 effectively restrict the sliding of the long side of the optical sheet 8, and at the same time provide an alignment reference for the transverse long side of the optical sheet 8, ensuring that the optical sheet 8 is accurately placed.

[0024] Preferably, the longitudinal baffle 3 is vertically and flexibly positioned in the longitudinal direction outside the frame 1. The longitudinal baffle 3 works in conjunction with the transverse baffle 2 to restrict the sliding of the wide edge of the optical sheet 8, while simultaneously providing an alignment reference for the longitudinal wide edge of the optical sheet 8, achieving precise positioning. The longitudinal baffle 3 is configured to be vertically adjustable; when the optical sheet 8 is placed beyond the transverse and longitudinal range of the air-bearing platform 4, the longitudinal baffle 3 can be lowered to ensure a more stable attachment operation.

[0025] Preferably, the system also includes a pneumatic valve switch 5, which is electrically connected to the longitudinal baffle 3. The pneumatic valve switch 5 can control the longitudinal baffle 3 to rise or fall. The pneumatic valve switch 5 includes an up button 501 and a down button 502. Pressing the up button 501 controls the longitudinal baffle 3 to rise, and pressing the down button 502 controls the longitudinal baffle 3 to fall. The air-floating platform 4 controls the airflow through the pneumatic valve switch 5, enabling the platform to obtain buoyancy, reducing the friction between the optical sheet 8 and the platform, facilitating rapid adjustment of the position of the optical sheet 8, and thus improving operating efficiency.

[0026] like Figure 1 and Figure 2 As shown, preferably, it also includes an air-blowing switch 6. The air-float platform 4 includes air-float beads 401 and an air cushion generator (not shown in the figure). The air-float beads 401 are uniformly embedded on the platform surface of the air-float platform 4. The air cushion generator (not shown in the figure) blows compressed air onto the platform surface of the air-float platform 4, causing the air-float beads 401 to guide the airflow and distribute the airflow evenly, forming a stable air cushion layer, so that the optical sheet 8 can be suspended or adsorbed on the air-float platform 4, thereby achieving frictionless movement. The air-blowing switch 6 includes an air-blowing button 601, an air-inhalation button 602, and a shut-off button 603. Pressing the air-blowing button 601 causes the air-float platform 4 to spray airflow through the gaps around the air-float beads 401, allowing the optical sheet 8 to suspend on the air-float platform 4. Pressing the air-inhalation button 602 causes the air cushion generator (not shown in the figure) of the air-float platform 4 to draw in air, and the air-float beads 401 guide the gas to distribute the gas evenly, causing the optical sheet 8 to adhere tightly to the air-float platform 4. Of course, the air-float platform 4 conventionally used in the prior art can also be used.

[0027] Preferably, it further includes a U-shaped groove 7 for accommodating the side sticker 9, wherein the U-shaped groove 7 is located opposite the transverse baffle 2 and below the frame 1, or / and the U-shaped groove 7 is located opposite the longitudinal baffle 3 and below the frame 1. Preferably, the U-shaped groove 7 is located opposite the transverse baffle 2 and below the frame 1 to accommodate the side sticker 9 in the transverse direction; the U-shaped groove 7 is located opposite the longitudinal baffle 3 and below the frame 1 to accommodate the side sticker 9 in the longitudinal direction. This arrangement achieves convenient storage and retrieval of the side sticker 9.

[0028] Preferably, at least two side adhesive strips 9 are grouped together. Optionally, two side adhesive strips 9 are grouped together; optionally, five side adhesive strips 9 are grouped together; optionally, fifteen side adhesive strips 9 are grouped together. Figure 3 and 4 As shown, the most preferred arrangement is that the side stickers are grouped into sets of ten, which improves efficiency, facilitates counting, and enhances operational feasibility.

[0029] Preferably, the optical sheet 8 is a light guide plate or a diffuser plate.

[0030] Preferably, the device also includes casters 10, which are located at the four lower corners of the frame 1 for easy movement of the equipment. Additionally, fixed support feet 11 at the bottom of the frame 1 provide stable support.

[0031] Preferably, the longitudinal baffle 3 is located at one-third of the left side of the frame 1, close to the transverse baffle 2, which facilitates the operation of the side sticker 9 and provides a more spacious and unobstructed operating space.

[0032] In use, taking the optical sheet 8 as an example of a light guide plate, precisely cut the required length and width of the side stickers 9 according to the product size, shape, and reserved gaps, with ten stickers forming a group. Apply adhesive to the back of the side stickers 9, attach them to the release paper, apply a transparent PE film without adhesive residue to the front, and place them in the corresponding U-shaped groove 7. Clean the optical sheet 8, with ten sheets forming a group. Hold the bottom of the optical sheet 8 with both hands and place it neatly on the air flotation platform 4. Press the rise button 501 of the pneumatic valve switch 5 to raise the longitudinal baffle 3. Activate the air blowing button 601 of the air blowing switch 6, blowing air through the air cushion generator (not shown in the figure) of the air flotation platform 4. The air float 401 guides the gas, evenly distributing the blown gas, so that the optical sheet 8 is suspended under the action of gravity. Push the optical sheet 8 to the upper left corner, position it through the horizontal baffle 2 and the longitudinal baffle 3, and use a rubber mallet to tap the four edges of the L-shaped side of the optical sheet 8 to align it. Press the descent button 502 on the pneumatic valve switch 5 to lower the longitudinal baffle 3. Move the optical sheet 8 along the horizontal and vertical sides of the air-float platform 4 towards the edge until both the horizontal and vertical edges of the optical sheet extend 50mm beyond the air-float platform. Press the suction button 602 to allow the air cushion generator (not shown in the figure) of the air-float platform 4 to draw in air. The air float 401 guides the gas, evenly distributing the gas and fixing the optical sheet 8 in place. First, wipe the sides of the optical sheet 8 from left to right with a lint-free cloth. Then, take out the side sticker 9 from the U-shaped groove 7, ensuring it is attached from left to right, with the head of the side sticker 9 precisely aligned with the left edge of the optical sheet 8 and aligned with the top and bottom edges of the optical sheet 8. Control the direction and position of the side sticker 9 with your right hand, and then press it firmly against the side sticker 9 with your left hand. After attachment, carefully visually inspect the side sticker 9 to ensure there are no bubbles, wrinkles, and it is firmly adhered. Finally, press the off button 603 to shut off the air intake of the air flotation platform 4, completing the application of ten side adhesive strips 9 in one go. Then, transfer the optical sheet 8 from the air flotation platform 4 to the trolley awaiting the next process. The image shows the optical sheet 8 with the side adhesive strips 9 applied. Figure 3 As shown.

[0033] This utility model provides a multi-piece mounting fixture for side-mounting optical sheets, which enables efficient batch processing of side-mounting 9 of optical sheets 8, improves production efficiency, and reduces labor intensity.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
