Description

Technical Field

[0001] The invention relates to the technical field of liquid crystal screen laminating devices, and in particular to a laminating machine. Background Art

[0002] Liquid crystal display, also known as LCD in English, is a type of flat panel display used for screen display of televisions and computers. The advantages of this display are low power consumption, small size and low radiation. In the field of liquid crystal display preparation, the glass substrate (also known as glass panel) is a basic component of the liquid crystal display device.

[0003] However, the current LCD screen has the following problems during the lamination process (i.e. the process of laminating the polarizer film on the panel):

[0004] 1. Manual lamination has the problems of low efficiency and high cost;

[0005] 2. Use traditional mechanized laminating equipment for laminating process:

[0006] When using traditional laminating equipment, the laminating alignment is prone to be inaccurate during the laminating process, which affects the quality of LCD screen laminating.

[0007] When using traditional laminating equipment, the polarizer film and the glass substrate (also known as glass panel) are often not pressed tightly during the lamination process, resulting in the opening and closing of the attachment surface, affecting the lamination quality; especially if the edge of the polarizer film is not pressed in place, the peripheral end surface of the polarizer film and the glass substrate are often not pressed tightly, affecting the quality of the lamination. Summary of the invention

[0008] To solve the problem mentioned in the above background technology: the existing laminating equipment often does not tightly press the polarizer film and the glass substrate (also known as the glass panel) during the laminating process, resulting in the opening and closing of the attachment surface, which affects the laminating quality;

The clamping member is slidably connected to the mounting frame and is connected to the output end of the second driving mechanism, so that the second driving mechanism drives the clamping member to move vertically on the mounting frame. The bottom surface height of the pulling wheel is lower than that of the clamping member, so that the writing paper is led out from the first clamping mechanism, passes above the positioning wheel, below the pressing wheel, below the pulling wheel in sequence, and is connected to the clamping member.

[0015] In one embodiment, the loading stage assembly includes a first loading stage. Above the first loading stage, a panel alignment camera assembly and a film - covering assembly are arranged in sequence along the transmission direction of the first loading stage. The panel alignment camera assembly is used to collect the image of the panel when it is on the first loading stage to detect the position of the panel.

[0016] In one embodiment, a fixture for placing the panel is arranged on the first loading stage.

[0017] In one embodiment, the panel alignment camera assembly includes a first alignment camera and a first multi - directional movement mechanism. The first multi - directional movement mechanism is connected to the first alignment camera and is used to drive the first alignment camera to move in multiple directions.

[0018] In one embodiment, the first multi - directional movement mechanism includes a first X - axis movement component and a first Y - axis movement component. The first alignment camera is arranged on the first X - axis movement component, so that the first X - axis movement component drives the first alignment camera to move horizontally. The first X - axis movement component is connected to the first Y - axis movement component, so that the first Y - axis movement component drives the first alignment camera to move vertically.

[0019] In one embodiment, a polarizer film alignment component is arranged below the film - covering assembly, and is used to collect the image when the polarizer film is attached to the writing paper to detect the position of the polarizer film.

[0020] In one embodiment, the polarizer film alignment component includes a second alignment camera and a second multi - directional movement mechanism. The second multi - directional movement mechanism is connected to the second alignment camera and is used to drive the second alignment camera to move in multiple directions.

[0021] In one embodiment, the second multi-directional movement mechanism includes a second X-axis movement component and a second Y-axis movement component; the second alignment camera is installed on the second X-axis movement component so that the second X-axis movement component drives the second alignment camera to move horizontally, and the second X-axis movement component is connected to the second Y-axis movement component so that the second Y-axis movement component drives the second alignment camera to move vertically.

[0050] For the purposes of making the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention; the technical features designed in different implementation manners of the present invention described below can be combined with each other as long as they do not conflict with each other; all other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0051] In the description of the present invention, it should be noted that all terms (including technical terms and scientific terms) used in the present invention have the same meanings as those generally understood by those of ordinary skill in the art to which the present invention pertains, and should not be construed as limiting the present invention; it should be further understood that the terms used in the present invention should be understood as having meanings consistent with their meanings in the context of this specification and the relevant art, and should not be understood in an idealized or overly formal sense, unless clearly defined as such in the present invention.

[0052] The present invention provides a film laminating machine as shown in Figure 1-11 Figure 19, which includes a machine table 100, a loading stage assembly 200 installed on the machine table 100 for carrying a panel 700, and a film laminating assembly 300; the film laminating assembly 300 includes:

[0053] A bracket 310 and a flipping mechanism 320, the flipping mechanism 320 is in transmission connection with the bracket 310 for driving the bracket 310 to flip;

[0054] A writing paper tensioning mechanism 330, which is installed on the bracket 310 and includes a first clamping mechanism 331 and a second clamping mechanism 332 respectively for clamping both ends of a writing paper 600;

[0055] The film laminating wheel assembly 340 is slidably connected to the bracket 310 so that it can move horizontally along the bracket 310. It includes a positioning wheel 341 and a pressing wheel 342. The bottom surface height of the positioning wheel 341 is higher than that of the pressing wheel 342, so that the writing paper 600 is led out from the first clamping mechanism 331, passes above the positioning wheel 341 and below the pressing wheel 342 in sequence and is connected to the second clamping mechanism 332. Among them, through the height settings of the first clamping mechanism 331 and the positioning wheel 341, the section of the writing paper 600 led out from the first clamping mechanism 331 and passing above the positioning wheel 341 is horizontally arranged.

[0056] Specifically, as Figure 1-11 shown, the working process of the film laminating machine is as follows:

[0057] The first clamping mechanism 331 and the second clamping mechanism 332 of the writing paper tensioning mechanism 330 first clamp and tension the writing paper 600. At this time, the writing paper 600 is led out from the first clamping mechanism 331, passes above the positioning wheel 341 and below the pressing wheel 342 in sequence and is connected to the second clamping mechanism 332;

[0058] The flipping mechanism 320 drives the bracket 310 to flip downward, thereby driving the entire film laminating assembly 300 to flip. The writing paper tensioning mechanism 330 rolls and adheres the polarizer film placed below it onto the writing paper 600;

[0059] The flipping mechanism 320 drives the bracket 310 to flip upward, driving the entire film laminating assembly 300 with the adhered polarizer film to flip. After the panel 700 is moved to below the film laminating assembly 300 through the loading platform assembly 200, the flipping mechanism 320 drives the bracket 310 to flip downward again, pressing and laminating the polarizer film adhered to the writing paper 600 onto the panel 700;

[0060] The film laminating wheel assembly 340 moves horizontally. Since the writing paper 600 is led out from the first clamping mechanism 331, passes above the positioning wheel 341 and below the pressing wheel 342 in sequence and is connected to the second clamping mechanism 332, as the film laminating wheel assembly 340 moves, the positioning wheel 341 and the pressing wheel 342 press the polarizer film again, making the polarizer film tightly pressed and adhered to the panel 700;

[0061] After the pressing is completed, the flipping mechanism 320 drives the bracket 310 to flip upward, that is, the overall film laminating process is completed.

[0062] The laminating assembly 300 of the present invention is provided with a flipping mechanism 320, a writing paper tensioning mechanism 330, and a laminating wheel assembly 340. Through the cooperation of the flipping mechanism 320, the laminating wheel assembly 340, and the writing paper tensioning mechanism 330, the polarizing film rolled on the writing paper 600 can be quickly pasted and pressed onto the panel 700. At the same time, through the laminating wheel assembly 340, the polarizing film pasted on the surface of the panel 700 can be pressed a second time, and the polarizing film and the panel 700 are tightly pressed together, effectively avoiding the problem that the attachment surface opens and closes due to the loose pressing of the polarizing film, which affects the laminating quality.

[0063] It should be noted that:

[0064] The writing paper 600 is a conventional material. According to the above design concept, those skilled in the art can make an adaptive selection in the market;

[0065] In this embodiment, the lengths of the clamping members 3324 of the first clamping mechanism 331 and the second clamping mechanism 332 are both equal to or greater than the width of the writing paper 600, and the lengths of the positioning wheel 341 and the pressing wheel 342 are also equal to or greater than the width of the writing paper 600. When in use, the width of the selected writing paper 600 is greater than or equal to the width of the polarizing film. Such a setting is beneficial for the writing paper 600 to be completely clamped by the writing paper tensioning mechanism 330, and is beneficial for the complete pressing of the polarizing film, and its peripheral end faces can also be well compacted, improving the laminating quality. According to the above design concept, the lengths of the clamping members 3324 in the first clamping mechanism 331 and the second clamping mechanism 332, the length of the positioning wheel 341, and the length of the pressing wheel 342 can all be adaptively adjusted according to the actual width of the panel 700 and the width of the polarizing film.

[0066] Preferably, the second clamping mechanism 332 includes a mounting frame 3321, a pulling wheel 3322, a second driving mechanism 3323, and a clamping member 3324 mounted on the mounting frame 3321; the clamping member 3324 is slidably connected to the mounting frame 3321 and is connected to the output end of the second driving mechanism 3323, so that the second driving mechanism 3323 drives the clamping member 3324 to move vertically (i.e., Z-axis movement) on the mounting frame 3321; the height of the bottom surface of the pulling wheel 3322 is lower than the height of the clamping member 3324, so that the writing paper 600 is led out from the first clamping mechanism 331, passes above the positioning wheel 341, below the pressing wheel 342, and below the pulling wheel 3322 in sequence and is connected to the clamping member 3324.

[0067] As Figure 1-11 shown, during the working process of the laminating assembly 300, the first clamping mechanism 331 and the second clamping mechanism 332 of the writing paper tensioning mechanism 330 tighten the writing paper 600, so as to roll the polarizing film on the writing paper 600 and paste the polarizing film adhered to the writing paper 600 onto the panel 700;

[0068] The second clamping mechanism 332 is provided with a pulling wheel 3322, a second driving mechanism 3323 and a clamping member 3324. During use, the clamping member 3324 and the first clamping mechanism 331 cooperate to clamp both ends of the writing paper 600. Since the writing paper 600 is led out from the first clamping mechanism 331, it passes above the positioning wheel 341, below the pressing wheel 342, below the pulling wheel 3322 in sequence and is connected to the clamping member 3324. Specifically, as Figure 8-9 shown, the second driving mechanism 3323 drives the clamping member 3324 to move up and down, so that the relative height between the pulling wheel 3322 and the clamping member 3324 changes, making the writing paper 600 tightened, which is convenient for the processes of rolling and sticking the polarizing film on the writing paper 600 and pasting the polarizing film adhered to the writing paper 600 onto the panel 700. Moreover, the tightening adjustment process of the writing paper tightening mechanism 330 is automated, improving the production efficiency.

[0069] It should be noted that:

[0070] The second driving mechanism 3323 in this embodiment is a driving mechanism that drives the clamping member 3324 to perform a reciprocating linear motion in the vertical direction; according to the above design concept, an existing reciprocating linear motion mechanism can be adopted, such as a pneumatic / hydraulic cylinder, etc. Those skilled in the art can adaptively select a suitable type or model, including but not limited to the above solutions.

[0071] Preferably, the flipping mechanism 320 includes a first driving mechanism 321, and the output end of the first driving mechanism 321 is rotatably connected to the bracket 310, so that the first driving mechanism 321 drives the bracket 310 to flip.

[0072] It should be noted that:

[0073] The first driving mechanism 321 in this embodiment adopts a linear motion electric cylinder. By rotatably connecting the output end of the first driving mechanism 321 to the bracket 310 (such as hinged connection), the linear reciprocating motion of the linear motion electric cylinder drives the bracket 310 to flip; according to the above design concept, an existing reciprocating linear motion mechanism can be adopted, such as a crank-slider mechanism, a gear-rack mechanism, a pneumatic / hydraulic cylinder, etc. Those skilled in the art can adaptively select a suitable type, including but not limited to the above solutions.

[0074] According to the above design concept, the flipping mechanism 320 can also adopt other structures and configurations capable of flipping the bracket 310, including but not limited to the solution of this embodiment.

[0075] Preferably, the first clamping mechanism 331 is detachably connected to the bracket 310, and the second clamping mechanism 332 is detachably connected to the bracket 310.

[0076] During use, the size of the polarizer film usually needs to be adjusted according to the size of the panel 700, so the size specification of the writing paper 600 needs to be adjusted; this setting facilitates the replacement of the first clamping mechanism 331 and the second clamping mechanism 332, so that the user can replace the suitable first clamping mechanism 331 and the second clamping mechanism 332 according to the actual size specification of the writing paper 600; at the same time, it also facilitates the maintenance and repair of the first clamping mechanism 331 and the second clamping mechanism 332.

[0077] Preferably, a slide rail is provided on the bracket 310, the film laminating wheel assembly 340 is slidably connected to the slide rail, and the film laminating wheel assembly 340 is driven to move along the slide rail by a fifth driving mechanism, which can be driven by an existing reciprocating linear motion mechanism. According to the above design concept, those skilled in the art can adaptively select a suitable type and model.

[0078] Preferably, the first carrier 210 is slidably connected to the machine table 100, and a third driving mechanism 230 is provided on the first carrier 210 to drive the first carrier 210 to move horizontally (i.e., move along the X-axis). Further preferably, a registration platform is provided below the first carrier 210. The first carrier 210 can not only move along the X-axis, but also a third Y-axis moving component 260 and a rotating component 270 are provided on its bottom surface to drive the first carrier 210 to perform multi-directional movement (that is, the first carrier 210 can move left and right, move forward and backward or rotate).

[0079] As Figure 1-11 shown, the first carrier 210 is driven by the third driving mechanism 230 to move horizontally along the machine table 100, so that the first carrier 210 moves back and forth below the panel alignment camera assembly 400 and below the film laminating assembly 300. This setting has a high degree of equipment automation and is convenient to use.

[0080] Preferably, the loading carrier assembly 200 includes a first carrier 210; above the first carrier 210, a panel alignment camera assembly 400 and a film laminating assembly 300 are sequentially provided along the transmission direction of the first carrier 210. The panel alignment camera assembly 400 is used to collect an image of the panel 700 when it is on the first carrier 210 to detect the position of the panel 700.

[0081] As Figure 1-11As shown in the figure, a panel alignment camera assembly 400 and a film laminating assembly 300 are sequentially arranged above the first carrier table 210. When the film laminating machine is in use, the first carrier table 210 is located below the panel alignment camera assembly 400. At this time, the operator performs the feeding operation of the panel 700, places the panel 700 on the station of the first carrier table 210 (i.e., on the fixture 220). The panel alignment camera assembly 400 is set to be able to collect the image of the panel 700 when it is on the first carrier table 210 to detect the position of the panel 700, so that the feeding position of the panel 700 can be accurately detected through the panel alignment camera assembly 400; if the position of the panel 700 is inaccurate, the first carrier table 210 can adjust its orientation according to the information fed back by the alignment camera assembly 400 to correct the panel 700 product (the first carrier table 210 performs X-axis movement, Y-axis movement or rotation) to make the placement position of the panel 700 accurate; then it moves to below the film laminating assembly 300 for film laminating, so as to ensure the accuracy of the film laminating position when the panel 700 is subsequently transferred to below the film laminating assembly 300 for the film laminating process, thereby ensuring the film laminating quality.

[0082] Preferably, a fixture 220 for placing the panel 700 is installed on the first carrier table 210.

[0083] The fixture 220 is set to place the panel 700, making the positioning of the panel 700 more accurate and the placement more stable. When in use, the fixture 220 moves horizontally with the first carrier table 210, so that the fixture 220 carries the panel 700 and moves back and forth below the panel alignment camera assembly 400 and below the film laminating assembly 300.

[0084] It should be noted that in the technical field, the relatively conventional and common shape of the panel 700 is rectangular. In this embodiment, the fixture 220 with a rectangular structure groove is adopted to match the rectangular panel 700; according to the above design concept, those skilled in the art can adjust the shape and structure of the fixture 220 according to the actual situation of the panel 700 to make it adapt to the shape of the panel 700, including but not limited to the embodiment scheme.

[0085] Preferably, a second carrier table 240 for carrying the polarizing film is provided on the machine table 100. The second carrier table 240 is slidably connected to the machine table 100, and a fourth driving mechanism 250 is provided on the second carrier table 240 to drive the second carrier table 240 to move longitudinally below the film laminating assembly 300.

[0086] As Figure 1-11As shown in the figure, the fourth driving mechanism 250 drives the second carrier table 240 to move longitudinally along the machine table 100 (i.e., move along the Y-axis), so that the second carrier table 240 moves back and forth directly below the film laminating assembly 300 and below the rear side of the film laminating assembly 300. During the process of the film laminating wheel assembly 340 rolling and sticking the polarizing film, a polarizing film is placed on the second carrier table 240 and moved directly below the film laminating assembly 300. The film laminating wheel assembly 340 rolls and sticks the polarizing film onto the writing paper 600, and then the second carrier table 240 is driven by the fourth driving mechanism 250 to move below the rear side of the film laminating assembly 300.

[0087] With such a setting, the fourth driving mechanism 250 drives the second carrier table 240 to move longitudinally along the machine table 100, and the automation degree of the equipment is high, which is convenient to use.

[0088] It should be noted that the third driving mechanism 230 and the fourth driving mechanism 250 are existing reciprocating linear motion mechanisms. According to the above design concept, those skilled in the art can adaptively select appropriate types, including but not limited to the above solutions.

[0089] Preferably, the panel alignment camera assembly 400 includes a first alignment camera 410 and a first multi-directional motion mechanism 420; the first multi-directional motion mechanism 420 is connected to the first alignment camera 410 to drive the first alignment camera 410 to move in multiple directions.

[0090] Preferably, the first multi-directional motion mechanism 420 includes a first X-axis moving component 421 and a first Y-axis moving component 422; the first alignment camera 410 is installed on the first X-axis moving component 421, so that the first X-axis moving component 421 drives the first alignment camera 410 to move horizontally, and the first X-axis moving component 421 is connected to the first Y-axis moving component 422, so that the first Y-axis moving component 422 drives the first alignment camera 410 to move longitudinally.

[0091] With such a setting, the first alignment camera 410 can adjust its position in multiple directions, can be accurately positioned at the required position, has good flexibility and strong applicability; at the same time, the transfer automation of the first alignment camera 410 can significantly improve production efficiency.

[0092] Preferably, a polarizing film alignment component 500 is provided below the film laminating assembly 300 to collect an image when the polarizing film is attached to the writing paper 600 to detect the position of the polarizing film.

[0093] Such as Figure 1-11As shown in the figure, before the laminating assembly 300 performs the laminating process, the polarizer film rolling and sticking process is first carried out by the laminating wheel assembly 340. The laminating wheel assembly 340 rolls and sticks the polarizer film onto the writing paper 600. The polarizer film alignment assembly 500 located below the laminating assembly 300 can collect the image of the polarizer film when it is attached to the writing paper 600 to detect the position of the polarizer film, so as to accurately judge whether the adhesion position of the polarizer film is aligned. After judging that its position is accurate, the laminating process is carried out, so as to ensure the accuracy of the laminating position and thus guarantee the laminating quality.

[0094] Preferably, the polarizer film alignment assembly 500 includes a second alignment camera 510 and a second multi-directional movement mechanism 520; the second multi-directional movement mechanism 520 is connected to the second alignment camera 510 for driving the second alignment camera 510 to move in multiple directions.
