Description

Technical Field

[0001] This invention relates to the field of backlight module manufacturing technology, and in particular to a backplate adhesive application assembly and adhesive application machine. Background Technology

[0002] Backlight modules are widely used in LCD screens. With the current trend of narrow bezels and large screens, in addition to making the LCD bezels narrower, the bezels of the backlight modules also need to be narrower. This requires the use of adhesive to attach the display panel, touch panel, or protective cover. The adhesive serves to fix and block light.

[0003] In existing automated production technologies, when applying adhesive to the backplate of a backlight module, the backplate is typically transferred to the bonding station via a conveyor line, and then positioned using CCD vision inspection to determine the bonding location. However, since the thin backplate is machine-processed, it is difficult to guarantee that there is no warping or deformation upon arrival. During the adhesive bonding pressing process, the backplate may be flattened, disrupting its original positioning and affecting the bonding quality. Therefore, an additional leveling process is required before adhesive bonding, increasing equipment complexity and cost, and impacting overall processing efficiency. Summary of the Invention

[0004] In view of the above problems, one object of the present invention is to provide a backplate adhesive assembly that enables the backplate to be shaped during the process of moving to the adhesive application station, thereby ensuring positioning accuracy and improving the adhesive application effect.

[0005] Another object of the present invention is to provide an adhesive applicator employing the above-described backplate adhesive applicator assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A backsheet adhesive application assembly includes an application platform located on one side of a backsheet conveyor line and a lifting mechanism that travels back and forth between the application platform and the backsheet conveyor line. The application platform includes two symmetrically arranged support frames. A light-transmitting glass plate is provided on the upper surface of each support frame. Vacuum suction cups for fixing the edges and corners of the backsheet are provided on the light-transmitting glass plate. The lifting mechanism includes a support plate with a plurality of vacuum suction nozzles for adsorbing the backsheet. The support plate moves up and down between the two support frames. When the sides of the backsheet are supported by the light-transmitting glass plates on both sides, the support plate adsorbing the backsheet continues to descend, thereby shaping the backsheet and placing it flat on the application platform.

[0008] In particular, there are four translucent glass panels, corresponding to the four corners of the back panel, and they are interchangeable to fit back panel products of different sizes.

[0009] Specifically, a backlight is provided below the translucent glass plate to assist the CCD visual inspection above the attachment platform.

[0010] Specifically, the support plate has two vacuum nozzles at one end and one vacuum nozzle at the other end, thus providing three-point support for the back panel product.

[0011] In particular, the vacuum nozzle is shaped like a drum with pleats to achieve a shrinkage and cushioning function.

[0012] Specifically, the lifting mechanism also includes a slide rail extending from the back plate conveyor line to the attachment platform. A base plate is mounted on the slide rail via a slider, a vertical plate is mounted on the base plate, and an upward-output lifting cylinder is mounted on the vertical plate. A support plate is fixed to the output end of the lifting cylinder to realize the lifting action.

[0013] Specifically, limit plates are erected on the lower surface of the support plate and on both sides of the lifting cylinder. The limit plates are provided with a first buffer facing downward and a second buffer facing upward. A stop block is provided on the vertical plate and above the second buffer. When the first buffer touches the bottom plate, the support plate moves to the lower stroke limit; when the second buffer touches the stop block, the support plate moves to the upper stroke limit.

[0014] Specifically, the back plate conveyor line is designed with a segmented roller structure for easy docking with the lifting mechanism, so that the support plate can pick up or put down materials on the back plate conveyor line.

[0015] On the other hand, the present invention adopts the following technical solution:

[0016] An adhesive applicator that uses the aforementioned backplate adhesive applicator assembly.

[0017] In summary, the beneficial effects of the present invention are that the back panel adhesive assembly and adhesive applicator are designed with a specially structured adhesive platform and lifting mechanism, which allows for shaping actions to be performed simultaneously when the back panel is transported to the adhesive platform, ensuring that the back panel is placed flat, thereby improving positioning accuracy, ensuring adhesive application effect, eliminating additional shaping processes, reducing costs, and improving overall processing efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] In the description of this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Please see Figure 1 As shown, this preferred embodiment provides a backsheet adhesive application assembly, including an application platform 1 located on one side of the backsheet conveyor line 3 and a lifting mechanism 2 that travels back and forth between the application platform 1 and the backsheet conveyor line 3. The lifting mechanism 2 mainly operates by lifting, lowering, and translating; therefore, when connecting the application platform 1 and the backsheet conveyor line 3, both the application platform 1 and the backsheet conveyor line 3 must be adapted to each other.

[0026] The back panel conveyor line 3 is configured with a segmented roller structure to facilitate docking with the lifting mechanism 2, so that the support plate 21 can pick up and place the back panel product 4 on the back panel conveyor line 3.

[0027] The attachment platform 1 is designed as a two-sided split structure, as detailed below. Figure 2As shown, it includes two symmetrically arranged support frames 11. The upper surface of each support frame 11 is provided with a light-transmitting glass plate 12. Vacuum suction cups 13 are provided on the light-transmitting glass plate 12 to fix the edges and corners of the back panel. Each vacuum suction cup 13 can independently control the adsorption and release of the back panel product 4.

[0028] Preferably, four light-transmitting glass panels 12 are provided, corresponding to the four corners of the back panel, and the design is replaceable to adapt to back panel products 4 of different sizes.

[0029] Furthermore, a backlight 14 is provided below the light-transmitting glass plate 12 to assist the CCD visual inspection above the attachment platform 1.

[0030] like Figure 3 As shown, the lifting mechanism 2 includes a support plate 21 and a slide rail 22 extending from the back plate conveyor line 3 to the attachment platform 1. A base plate 23 is mounted on the slide rail 22 via a slider. A vertical plate 24 is mounted on the base plate 23. A lifting cylinder 25 that outputs upwards is mounted on the vertical plate 24. The support plate 21 is fixed to the output end of the lifting cylinder 25 to realize the lifting action.

[0031] The support plate 21 is provided with a number of vacuum nozzles 26 for adsorbing the back panel. Preferably, one end of the support plate 21 is provided with two vacuum nozzles 26 and the other end is provided with one vacuum nozzle 26, so as to form a three-point support for the back panel product 4, simplifying the structure as much as possible and reducing the complexity of the structure.

[0032] It is worth mentioning that the vacuum nozzle 26 here is drum-shaped and pleated, which realizes the shrinkage buffer function, improves the flexibility of the equipment, and avoids damage to the back panel product 4.

[0033] Therefore, the support plate 21 moves up and down between the two support frames 11. When the sides of the back panel are supported by the light-transmitting glass plates 12 on both sides, the support plate 21 adsorbing the back panel product 4 continues to descend, applying a downward pulling force to flatten it, thereby shaping the back panel and placing it flat on the attachment platform 1. Of course, this descent is relatively small, and during the shaping process, the vacuum suction cup 13 does not immediately adhere to the back panel product 4, but only adsorbs and positions it the instant the shaping is completed.

[0034] In addition, limit plates 27 are erected on the lower surface of the support plate 21 and on both sides of the lifting cylinder 25. The limit plates 27 are provided with a first buffer 28 facing downward and a second buffer 29 facing upward. A stop is provided on the upright plate 24 above the second buffer 29. When the first buffer 28 touches the base plate 23, the support plate 21 moves to the lower stroke limit; when the second buffer 29 touches the stop, the support plate 21 moves to the upper stroke limit, thereby ensuring the stable and reliable operation of the mechanism.

[0035] In summary, the aforementioned backplate adhesive application assembly features a specially designed application platform and lifting mechanism. This allows for shaping during the transfer of the backplate to the application platform, ensuring the backplate is placed flat. This improves positioning accuracy, guarantees the adhesive application effect, eliminates the need for additional shaping processes, and reduces costs. Integrating this backplate adhesive application assembly into an adhesive application machine can significantly improve overall processing efficiency.

[0036] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above examples. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
