Description

Technical Field

[0001] This utility model belongs to the technical field of liquid crystal display manufacturing equipment, specifically relating to an automatic bonding device for explosion-proof film and glass cover plate. Background Technology

[0002] In the manufacturing process of LCD screens, to better protect the display products, an explosion-proof film is applied simultaneously during the bonding and assembly process, ensuring the product is protected before leaving the factory. In existing bonding and assembly processes, the explosion-proof film is first bonded to the first surface of a glass cover plate. Then, the second surface of the glass cover plate is bonded to the display panel using OCA optical adhesive to obtain the display module. Finally, the display module and backlight module are bonded and assembled to form the display product. Currently, the bonding process between the explosion-proof film and the glass cover plate is typically performed manually or semi-manually using auxiliary fixtures, resulting in lower production efficiency.

Examples of these preferred embodiments are illustrated in the drawings. The embodiments of this utility model shown in and described with reference to the drawings are merely exemplary, and this utility model is not limited to these embodiments.

[0039] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0040] This utility model embodiment provides an automatic bonding device for explosion-proof film and glass cover plate, such as... Figure 1 As shown, the automatic bonding device for the explosion-proof film and the glass cover mainly includes a frame platform 100 and a bonding unit 3, a first feeding unit 1, and a second feeding unit 2 connected to the frame platform 100. The bonding unit 3 is disposed at the first end of the frame platform 100. The first feeding unit 1 and the second feeding unit 2 are spaced apart from each other along a second direction (the width direction of the frame platform 100 in this embodiment) and extend from the second end of the frame platform 100 along a first direction (the length direction of the frame platform 100 in this embodiment) to the bonding unit 3.

[0041] The first feeding unit 1 supplies glass cover plates to the bonding unit 3 and cleans the glass cover plates. The second feeding unit 2 supplies explosion-proof film to the bonding unit 3 and cleans the explosion-proof film. The bonding unit 3 is used to peel off the received explosion-proof film, perform visual positioning, visually position the received glass cover plates, and precisely align the original explosion-proof film on the glass cover plates before bonding them together.

[0042] In this embodiment, see Figure 1 , Figure 2 , Figure 4 as well as Figures 6 to 10 The first feeding unit 1 includes a flipping platform 1a, a first transfer subunit 1b, a second transfer subunit 1c, and a third transfer subunit 1d, sequentially connected between the second end of the frame platform 100 and the bonding unit 3. It also includes a first cleaning subunit 1e located below the second transfer subunit 1c. The flipping platform 1a receives the glass cover plate and flips it before sending it to the first transfer subunit 1b. The first transfer subunit 1b sends the glass cover plate received from the flipping platform 1a to the second transfer subunit 1c. The second transfer subunit 1c picks up the glass cover plate from the first transfer subunit 1b and sends it to the third transfer subunit 1d. The third transfer subunit 1d sends the glass cover plate received from the second transfer subunit 1c to the bonding unit 3. During the process of transferring the glass cover plate, when the second transfer subunit 1c moves the glass cover plate above the first cleaning subunit 1e, the first cleaning subunit 1e performs dust removal and cleaning on the glass cover plate.

[0043] As described above, the first feeding unit 1 can automatically feed the glass cover plate to the bonding unit 3 by sequentially conveying it through the flipping platform 1a, the first transfer subunit 1b, the second transfer subunit 1c, and the third transfer subunit 1d. When the second transfer subunit 1c picks up the glass cover plate and moves it above the first cleaning subunit 1e, the first cleaning subunit 1e performs dust removal and cleaning on the bonding surface of the glass cover plate to ensure that the glass cover plate can be firmly bonded to the explosion-proof film in the subsequent bonding process.

[0044] In this embodiment, see Figure 9 and Figure 10 and combined Figure 1 and Figure 2 As shown, the first cleaning subunit 1e includes an unwinding mechanism 11, a winding mechanism 12, a roller assembly 13, a pressing assembly 14, and a cleaning cloth 15. The cleaning cloth 15 is arranged in a roll shape in the unwinding mechanism 11. The cleaning cloth 15 is released from the unwinding mechanism 11, tensioned and connected above the roller assembly 13, and then wound back into the winding mechanism 12. The pressing assembly 14 is vertically and vertically disposed below the roller assembly 13. The pressing assembly 14 is configured to press the cleaning cloth 15 upwards onto the glass cover plate to clean the glass cover plate. It should be noted that... Figure 9 The cleaning cloth 15 is not shown in the image.

[0045] As described above, the first cleaning subunit 1e can configure the winding mechanism 12 as an active rotating mechanism and the unwinding mechanism 11 as a driven rotating mechanism. During the cleaning process of the glass cover plate, the cleaning cloth 15 is gradually transferred from the unwinding mechanism 11 to the winding mechanism 12. Specifically, when the second transfer subunit 1c feeds the glass cover plate above the roller assembly 13, the pressing assembly 14 presses the cleaning cloth 15 upwards onto the lower surface of the glass cover plate. By controlling the lateral movement of the glass cover plate and the transmission of the cleaning cloth 15 from the unwinding mechanism 11 to the winding mechanism 12, the cleaning cloth 15 performs dust removal and cleaning treatment on the lower surface of the glass cover plate (the bonding surface of the subsequent bonding process) by wiping.

[0046] In the first cleaning subunit 1e, a first guide roller group 16 is arranged between the unwinding mechanism 11 and the idler roller assembly 13 along the transmission path of the cleaning cloth 15, and a second guide roller group 17 is arranged between the idler roller assembly 13 and the winding mechanism 12. The cleaning cloth 15 released from the unwinding mechanism 11 is connected to the idler roller assembly 13 through the first guide roller group 16, and then connected to the winding mechanism 13 through the second guide roller group 17.

[0047] In a preferred embodiment, the idler assembly 13 includes a first idler 131, a second idler 132, a third idler 133, and a fourth idler 134 arranged sequentially on a first horizontal plane, and also includes a tension roller 135 located below the first horizontal plane and between the second idler 132 and the third idler 133. The cleaning cloth 15, released from the unwinding mechanism 11, is sequentially connected to the upper sides of the first idler 131 and the second idler 132, the lower side of the tension roller 135, and the upper sides of the third idler 133 and the fourth idler 134, and then wound back into the winding mechanism 12. The tension roller 135 is used to adjust the tension of the cleaning cloth 15 so that the cleaning cloth 15 is tautly connected to the first idler 131, the second idler 132, the third idler 133, and the fourth idler 134.

[0048] Furthermore, below the first horizontal plane, a top-pressing assembly 14 is respectively provided between the first idler roller 131 and the second idler roller 132, and between the third idler roller 133 and the fourth idler roller 134. Thus, the first cleaning subunit 1e can perform two sequential cleaning processes on the lower surface of the glass cover, achieving a better cleaning effect.

[0049] The top-pressing assembly 14 includes a lifting drive module 141 and a top-pressing structural member 142. The top-pressing structural member 142 is vertically and vertically connected to the output end of the lifting drive module 141 on the side facing the cleaning cloth 15. The top-pressing structural member 142 is an elongated plate extending along the width direction of the cleaning cloth 15.

[0050] Furthermore, the first cleaning subunit 1e also includes a cleaning agent spraying mechanism 18 disposed below the idler roller assembly 13 and located on the side of the top pressing assembly 14. The cleaning agent spraying mechanism 18 is used to spray cleaning agent onto the cleaning cloth 15 to further improve the cleaning effect.

[0051] In this embodiment, see Figure 1 , Figure 3 , Figure 5 , Figure 11 and Figure 12 The second feeding unit 2 includes an explosion-proof film hopper 2a, a fourth transfer subunit 2b, and a fifth transfer subunit 2c, sequentially connected between the second end of the frame platform 100 and the bonding unit 3. It also includes a second cleaning subunit 2d located above the fifth transfer subunit 2c. The explosion-proof film hopper 2a is used for stacking and storing explosion-proof films. The fourth transfer subunit 2b is used to grab explosion-proof films from the explosion-proof film hopper 2a and feed them into the fifth transfer subunit 2c. The fifth transfer subunit 2c is used to feed the explosion-proof film received from the fourth transfer subunit 2b into the bonding unit 3. During the transfer of the explosion-proof film, when the fifth transfer subunit 2c moves the explosion-proof film below the second cleaning subunit 2d, the second cleaning subunit 2d performs dust removal and cleaning on the explosion-proof film.

[0052] It should be noted that a release liner is usually attached to the bonding surface of the explosion-proof film. This release liner needs to be removed in the bonding unit 3 to expose the bonding surface before it is bonded to the glass cover. The second cleaning subunit 2d, as described above, mainly performs dust removal and cleaning on the surface of the release liner to prevent dust from falling onto the bonding surface of the explosion-proof film during the subsequent removal of the release liner.

[0053] As described above, the second feeding unit 2, through the sequential conveying of the explosion-proof film hopper 2a and the fourth transfer subunit 2b and the fifth transfer subunit 2c, can automatically feed the explosion-proof film to the bonding unit 3. Furthermore, when the fifth transfer subunit 2c moves the explosion-proof film below the second cleaning subunit 2d, the second cleaning subunit 2d performs dust removal and cleaning treatment on the release protective film on the surface of the explosion-proof film, preventing dust from falling onto the bonding surface of the explosion-proof film during the subsequent film peeling process, and ensuring that the explosion-proof film can be firmly bonded to the glass cover in the subsequent bonding process.

[0054] In this embodiment, see Figure 11 and Figure 12 and combined Figure 1 and Figure 5 As shown, the second cleaning subunit 2d includes a dust-adhesive roller assembly 21, which is vertically and flexibly connected above the fifth transfer subunit 2c. When the fifth transfer subunit 2c moves the explosion-proof film below the dust-adhesive roller assembly 21, the dust-adhesive roller assembly 21 presses against the explosion-proof film and rolls on its surface, thereby adhering and removing dust from the surface of the explosion-proof film. Furthermore, the fifth transfer subunit 2c is also connected to a dust-adhesive film assembly 22. When the dust-adhesive film assembly 22 moves with the fifth transfer subunit 2c below the dust-adhesive roller assembly 21, the dust-adhesive roller assembly 21 presses against the dust-adhesive film assembly 22 and rolls on its surface, so that dust adhering to the dust-adhesive roller assembly 21 is transferred to the dust-adhesive film assembly 22.

[0055] Specifically, the fifth transfer subunit 2c includes a linear drive mechanism 23 and a support platform 24. The support platform 24 is movably connected to the linear drive mechanism 23. The adhesive film assembly 22 is fixedly connected to the support platform 24 and moves in conjunction with the support platform 24 on the linear drive mechanism 23. The adhesive roller assembly 21 is vertically mounted above the linear drive mechanism 23. The support platform 24 is used to load the explosion-proof film fed in from the fourth transfer subunit 2b, combined with... Figure 11 As shown, the support platform 24 first receives the explosion-proof film at the left end of the linear drive mechanism 23, and then moves the loaded explosion-proof film to the right. When it moves to below the adhesive roller assembly 21, the adhesive roller assembly 21 descends and presses against the surface of the explosion-proof film. As the explosion-proof film continues to be transported to the right, the adhesive roller assembly 21 rolls on the surface of the explosion-proof film, thereby adhering to the dust on the surface of the explosion-proof film. The support platform 24 moves to the right, causing the adhesive film material assembly 22 to move below the adhesive roller assembly 21. At this time, the adhesive roller assembly 21 is controlled to roll on the adhesive film material assembly 22. The adhesive force of the adhesive film material assembly 22 is set to be greater than the adhesive force of the adhesive roller assembly 21, thereby transferring the dust adhering to the adhesive roller assembly 21 to the adhesive film material assembly 22. That is, the adhesive film material assembly 22 can be understood as a functional module for cleaning the adhesive roller assembly 21.

[0056] In this embodiment, see Figure 1 , Figure 4 , Figure 5 as well as Figures 13 to 18The bonding unit 3 includes a lower bonding platform 31, an upper bonding platform 32, an explosion-proof film transfer mechanism 33, an explosion-proof film tearing assembly 34, a first visual alignment assembly 35, and a second visual alignment assembly 36. The upper bonding platform 32 is located at the first end of the bonding unit 3 and docks with the first feeding unit 1, specifically with the third transfer subunit 1d of the first feeding unit 1. The explosion-proof film transfer mechanism 33 is located at the second end of the bonding unit 3 and docks with the second feeding unit 2, specifically with the fifth transfer subunit 2c of the second feeding unit 2. The lower bonding platform 31 extends along a second direction and is configured to reciprocate between the upper bonding platform 32 and the explosion-proof film transfer mechanism 33. The first visual alignment component 35 is disposed at the first end of the bonding unit 3 and located below the bonding upper platform 32, while the explosion-proof film tearing component 34 and the second visual alignment component 36 are disposed in the middle of the bonding unit 3 and mounted above the bonding lower platform 31.

[0057] The explosion-proof film transfer mechanism 33 is used to pick up and transfer the explosion-proof film fed from the second feeding unit 2 to the lower lamination platform 31. The lower lamination platform 31 is used to load the explosion-proof film and transfer it below the upper lamination platform 32. The explosion-proof film tearing assembly 34 is used to tear the explosion-proof film loaded on the lower lamination platform 31, removing the release protective film from the lamination surface of the explosion-proof film. The second visual alignment assembly 36 is used to visually position the explosion-proof film loaded on the lower lamination platform 31. The upper lamination platform 32 is used to pick up a glass cover plate from the first feeding unit 1 and lamination the glass cover plate onto the explosion-proof film loaded on the lower lamination platform 31, and also to transfer the laminated product to the outside of the automatic lamination device. The first visual alignment assembly 35 is used to visually position the glass cover plate picked up on the upper lamination platform 32.

[0058] Specifically, the lower bonding platform 31 includes a first linear drive assembly 311, a UVW platform 312, and a bonding mesh box 313. The first linear drive assembly 311 extends along a second direction and connects between the upper bonding platform 32 and the explosion-proof film transfer mechanism 33. The UVW platform 312 is movably connected to the first linear drive assembly 311, and the bonding mesh box 313 is connected to the UVW platform 312. The explosion-proof film tearing assembly 34 and the second visual alignment assembly 36 are disposed in the middle of the bonding unit 3 and mounted above the first linear drive assembly 311.

[0059] In this embodiment, the bonding unit 3 is provided with two bonding lower platforms 31, which are arranged in parallel in a first direction and extend along a second direction respectively. The two bonding lower platforms 31 can operate synchronously to improve production efficiency. For example, when one bonding lower platform 31 moves to the underside of the bonding upper platform 32 to perform bonding operations, the other bonding lower platform 31 can receive the explosion-proof film from the explosion-proof film transfer mechanism 33 and sequentially transfer the explosion-proof film to the underside of the explosion-proof film tearing assembly 34 and the second vision alignment assembly 36 to perform the tearing and vision positioning operations in sequence, reducing equipment waiting time and improving efficiency.

[0060] Specifically, the bonding platform 32 includes a second linear drive assembly 321 and a first gripping assembly 322. The second linear drive assembly 321 is located at the first end of the bonding unit 3 and is mounted above the frame platform 100. The second linear drive assembly 321 extends along a first direction. The first gripping assembly 322 is movably connected to the second linear drive assembly 321 and is configured to grip and move the glass cover plate. The explosion-proof film transfer mechanism 33 includes a third linear drive assembly 331 and a second gripping assembly 332. The third linear drive assembly 331 is located at the second end of the bonding unit 3 and is connected to the frame platform 100. The third linear drive assembly 331 extends along a first direction. The second gripping assembly 332 is movably connected to the third linear drive assembly 331 and is configured to grip and move the explosion-proof film.

[0061] The bonding unit 3 described above operates by including the following steps:

[0062] (1) The explosion-proof film transfer mechanism 33 picks up the explosion-proof film from the second feeding unit 2 and places it on the bonding mesh box 313 of the bonding lower platform 31.

[0063] (2) The lower bonding platform 31 first moves the loaded explosion-proof film toward the upper bonding platform 32 to below the explosion-proof film tearing assembly 34, and the explosion-proof film tearing assembly 34 tears off the release protective film on the bonding surface of the explosion-proof film.

[0064] (3) The bonding platform 31 continues to move the explosion-proof film below the second vision alignment component 36, and the second vision alignment component 36 obtains the positioning information of the explosion-proof film loaded on the bonding net box 313.

[0065] (4) The bonding platform 32 picks up the glass cover plate from the first feeding unit 1 and moves the glass cover plate above the first vision alignment component 35, and the first vision alignment component 35 obtains the positioning information of the glass cover plate picked up on the bonding platform 32.

[0066] (5) The lower bonding platform 31 moves the explosion-proof film below the upper bonding platform 32, and the upper bonding platform 32 moves the glass cover above the lower bonding platform 31. Based on the positioning information obtained in steps (3) and (4), the explosion-proof film and the glass cover are precisely aligned through the initial adjustment of the first linear drive component 311 and the second linear drive component 321, and through the precise adjustment of the UVW platform 312.

[0067] (6) After precise alignment, the upper bonding platform 32 presses the glass cover down onto the explosion-proof film on the lower bonding platform 31. The bonding mesh box 313, used to hold the explosion-proof film, is equipped with a lifting and rolling mechanism (not shown in the attached drawings). When the upper bonding platform 32 presses down the glass cover, the lifting and rolling mechanism presses the explosion-proof film upwards and rolls it, ensuring a tight fit between the explosion-proof film and the glass cover.

[0068] (7) The bonding platform 32 picks up the bonding products (the explosion-proof film and glass cover after bonding) and transfers the bonding products to the outside of the automatic bonding device for the next operation.

[0069] In summary, the automatic bonding device for explosion-proof film and glass cover provided in this embodiment integrates a first feeding unit for supplying and cleaning the glass cover, a second feeding unit for supplying and cleaning the explosion-proof film, and a bonding unit for bonding the explosion-proof film and glass cover into a single automatic bonding device. From the feeding and cleaning of the glass cover, to the feeding, cleaning, and tearing of the explosion-proof film, to the visual alignment of the glass cover and the explosion-proof film, and finally the bonding and unloading of the explosion-proof film to the next process, all processes are automated. This improves the bonding efficiency of the explosion-proof film and glass cover, thereby increasing the production efficiency of the LCD screen.

[0070] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
