Description

Technical Field

[0001] The present application relates to the technical field of laminating equipment, and in particular to a protective layer vacuum laminating equipment. Background Art

[0002] At present, in the production of display screens, a light-emitting layer must first be formed on a substrate, and then a protective layer must be adhered to the surface of the light-emitting layer using OCA glue (optical glue). The protective layer can be glass or a soft film to protect the light-emitting layer and ensure the normal operation of the screen.

[0003] In the related art, when the protective layer is bonded to the substrate, hard-to-hard pressing is usually adopted, that is, the protective layer is pressed onto the substrate on the platform using a pressing plate, and the protective layer is ensured to be tightly bonded to the substrate by applying force in a plane.

[0004] However, when the protective layer is a soft film, hard-to-hard flat pressing is adopted.

DETAILED DESCRIPTION

[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0054] The embodiment of the present application provides a protective layer vacuum laminating device, which utilizes the deformation of an arc-shaped elastic plate to gradually laminate the protective layer from the middle to the edge to the substrate, so that bubbles are not easily generated when the substrate and the protective layer are laminated. The present application solves the technical problem in the related art that after laminating the protective layer, bubbles are easily generated between the protective layer and the substrate, which affects the laminating quality of the protective layer.

[0055] Reference Figure 1 and Figure 2A protective layer vacuum laminating device includes a machine base 1 and a support module 2, a pressing module 3 and a transposition module 4 arranged on the machine base 1. The support module 2 is used for placing a substrate, the pressing module 3 is used for carrying a protective layer, and the transposition module 4 is drivingly connected to the support module 2 to drive the support module 2 to switch between a pressing station and a loading station. When the support module 2 is at the pressing station, the support module 2 and the pressing module 3 press and fix the substrate and the protective layer.

[0056] Reference Figure 2 and Figure 3 , wherein the support module 2 includes a support table 21 and a lifting assembly 22. The support table 21 is used for placing the substrate. It should be noted that the surface of the substrate has been coated with OCA glue. The lifting assembly 22 is connected to the support table 21 to drive the support table 21 to rise and fall. The lifting assembly 22 drives the support table 21 to rise so that the substrate is close to and fits the protective layer. In this embodiment, the lifting assembly 22 includes a cylinder, a screw mechanism or a linear motor.

[0057] Reference Figure 1 and Figure 2 The transposition module 4 is mounted on the machine base 1, and the driving end of the transposition module 4 is connected to the jacking assembly 22, so as to drive the support platform 21 to move together by driving the jacking assembly 22. In this embodiment, the driving direction of the transposition module 4 is a horizontal direction, and the transposition module 4 includes a screw mechanism or a linear motor.

[0058] Reference Figure 2 and Figure 3 Specifically, the support platform 21 includes a base 211 and a support adsorption platform 212. The support adsorption platform 212 is connected to the surface of the base 211 and is used to support and adsorb the substrate. The lifting component 22 is connected to the base 211 to drive the base 211 and the support adsorption platform 212 to rise and fall together.

[0059] Reference Figure 2 and Figure 3 , wherein the surface of the support adsorption platform 212 is provided with a plurality of adsorption holes, and the plurality of adsorption holes are all connected to the external negative pressure device, so as to fix the substrate on the surface of the support adsorption platform 212 by negative pressure adsorption. The substrate is fixed on the support adsorption platform 212 by adsorption to fix the position of the substrate. When the substrate is transferred, the position of the substrate is not easy to change, which facilitates the subsequent alignment of the substrate and the protective layer. In addition, when the substrate and the protective layer are pressed together, the substrate is not easy to move due to force, and the substrate and the protective layer are not easy to be misaligned, which facilitates the protective layer to be accurately attached to the substrate.

[0060] Reference Figure 2-Figure 4Furthermore, the support platform 21 also includes a positioning component 213, and the positioning component 213 is connected to the support adsorption platform 212. The positioning component 213 includes two positioning surfaces 213a, and the two positioning surfaces 213a are respectively used for the adjacent two side surfaces of the substrate to abut against. When the substrate is placed on the support adsorption platform 212, the adjacent two side surfaces of the substrate are respectively abutted against the two positioning surfaces 213a to preliminarily locate the placement position of the substrate, so as to facilitate the alignment of the substrate with the protective layer during the subsequent lamination process.

[0061] Reference Figure 3 and Figure 4 Specifically, the positioning assembly 213 includes two positioning blocks, both of which are fixed to the support adsorption platform 212 by bolts, and one side of the positioning block is the positioning surface 213a. In other embodiments, the positioning assembly 213 may include an L-shaped block, and the two positioning surfaces 213a are respectively two side surfaces of the L-shaped block.

[0062] Reference Figure 1 , Figure 2 and Figure 5 The pressing module 3 includes a frame 31 and a pressing plate group 32. The frame 31 is fixed on the base 1, and the pressing plate group 32 is connected to the frame 31. The pressing plate group 32 is used to absorb the protective layer. When the supporting module 2 is located at the pressing station, the pressing plate group 32 is located directly above the supporting module 2.

[0063] Reference Figure 1 , Figure 2 and Figure 5 The pressing plate group 32 includes an adsorption platform 321, an arc-shaped elastic plate 322 and multiple groups of elastic members 323. The bottom surface of the adsorption platform 321 is the adsorption surface, and a plurality of adsorption holes are provided on the bottom surface of the adsorption platform 321, and the plurality of adsorption holes are connected to the external negative pressure device. The arc-shaped elastic plate 322 is connected to the bottom surface of the adsorption platform 321 through multiple elastic members 323. The bottom surface of the arc-shaped elastic plate 322 is low in the middle and high at both ends. The arc-shaped elastic plate 322 is provided with multiple adsorption holes. The negative pressure device generates negative pressure below the adsorption platform 321, so that the bottom surface of the arc-shaped elastic plate 322 has negative pressure, and the arc-shaped elastic plate 322 can adsorb and fix the protective layer on the bottom surface of the arc-shaped elastic plate 322 through the adsorption platform 321.

[0064] In this embodiment, the protection layer is a flexible film, and the protection layer can fit the curved surface of the arc-shaped elastic plate 322 and be attached to the bottom surface of the arc-shaped elastic plate 322 .

[0065] In this way, when the protective layer and the substrate are pressed together, the lifting assembly 22 drives the support platform 21 and the substrate to rise, first contacting the middle of the protective layer, and as the substrate further rises, it squeezes the arc-shaped elastic plate 322, and the arc-shaped elastic plate 322 gradually deforms into a flat plate (refer to Figure 7), and the protective layer gradually contacts the substrate from the middle to the edge. Finally, since the arc-shaped elastic plate 322 is flat against the adsorption platform 321, the arc-shaped elastic plate 322 is flat and evenly presses the substrate and the protective layer to achieve the bonding of the substrate and the protective layer. Therefore, the protective layer gradually bonds to the substrate from the middle to the edge, and bubbles are not easily generated between the substrate and the protective layer, thereby improving the bonding quality of the protective layer and the substrate.

[0066] The bottom surface of the adsorption platform 321 is provided with a plurality of receiving holes for accommodating the elastic member 323, and the elastic member 323 can be retracted into the receiving holes. When the arc-shaped elastic plate 322 is deformed to a flat state, the elastic member 323 is retracted into the receiving hole. At this time, the top surface of the arc-shaped elastic plate 322 can be completely attached to the bottom surface of the adsorption platform 321, and the protective layer is evenly pressed as a whole, thereby improving the bonding quality of the protective layer and the substrate. In this embodiment, the elastic member 323 includes a spring, an elastic block or an elastic strip.

[0067] Reference Figure 6 Further, the pressing plate group 32 further includes a plurality of height adjusting members 324, and the number of the height adjusting members 324 is set corresponding to the number of the elastic members 323. The elastic members 323 are connected to the adsorption platform 321 through the height adjusting members 324. Specifically, one end of the elastic member 323 is fixed to the arc-shaped elastic plate 322, and the other end of the elastic member 323 is connected to the adsorption platform 321 through the height adjusting member 324. The plurality of height adjusting members 324 are suitable for changing the heights of the plurality of elastic members 323 respectively.

[0068] Reference Figure 6 and Figure 8 The height adjustment member 324 is disposed in the receiving hole. By changing the height of the elastic member 323 through the height adjustment member 324, the curvature of the arc-shaped elastic plate 322 can be changed. It should be noted that when the height of the elastic member 323 is changed to push the arc-shaped elastic plate 322 so that the arc-shaped elastic plate 322 is deformed, the elastic member 323 does not deform, that is, the elastic modulus of the elastic member 323 is greater than the elastic modulus of the arc-shaped elastic plate 322.

[0069] In this embodiment, the height adjustment member 324 includes a bolt, which is threadedly connected to the receiving hole, and the height of the elastic member 323 can be fine-tuned by rotating the height adjustment member 324. It should be noted that the arc shape of the arc-shaped elastic plate 322 changes slightly.

[0070] In this arrangement, since the curvature of the arc-shaped elastic plate 322 is adjustable, when the protective layer and the substrate are attached, the curvature of the arc-shaped elastic plate 322 can be adjusted to control the speed at which the middle to the edge of the protective layer gradually attaches to the substrate. The larger the curvature of the arc-shaped elastic plate 322, the smaller the area of ​​the protective layer attached to the substrate per unit time. The curvature of the arc-shaped elastic plate 322 can be adjusted accordingly according to the specific material of the protective layer and the specific softness of the protective layer to ensure that bubbles are not easily generated when the protective layer is attached to the substrate.

[0071] In some embodiments, multiple sets of elastic members 323 can be detachably connected to the adsorption platform 321. Optionally, the elastic members 323 are connected to the adsorption platform 321 in the form of threaded connection. That is, by removing the elastic members 323 from the adsorption platform 321, the arc-shaped elastic plate 322 can be removed at the same time.

[0072] In this configuration, the arc-shaped elastic plate 322 can be removed and replaced with an arc-shaped elastic plate 322 of different curvature, thereby expanding the adaptability to the laminating process of protective layers of different softness types. In addition, the arc-shaped elastic plate 322 can be removed, and the protective layer can be directly adsorbed by the adsorption platform 321, and the substrate and the protective layer can be pressed together by using the adsorption platform 321 and the support adsorption platform 212 to meet the laminating process requirements of the hard protective layer, which can include glass.

[0073] Reference Figure 1 and Figure 2 In some embodiments, further, the protective layer vacuum laminating device also includes a vacuum sealing component 5, and the vacuum sealing component 5 includes a first box body 51, a second box body 52, a lifting drive member 53 and a vacuum pumping component.

[0074] The first box body 51 is slidably arranged on the frame 31 up and down, and the pressing plate group 32 is connected to the first box body 51. The first box body 51 is provided with an opening at the bottom. The second box body 52 is slidably arranged on the base 1, the transposition module 4 is drivingly connected to the second box body 52 to drive the second box body 52 to slide on the base 1, the support module 2 is connected to the second box body 52 to slide with the second box body 52, and the support platform 21 is located in the second box body 52, and the second box body 52 is provided with an opening at the top. The lifting drive member 53 is installed on the frame 31, and the lifting drive member 53 is drivingly connected to the first box body 51 to drive the first box body 51 to move up and down. In this embodiment, the lifting drive member 53 includes a screw mechanism, a cylinder or a linear motor.

[0075] With this arrangement, when the substrate and the protective layer are pressed together, the lifting drive 53 first drives the first box 51 to descend, so that the first box 51 is buckled into the second box 52. At this time, the protective layer and the substrate are both located in the enclosed space formed by the first box 51 and the second box 52. Then, the lifting assembly 22 drives the support platform 21 to rise to achieve the lamination of the substrate and the protective layer. Since the lamination process of the substrate and the protective layer is carried out in a sealed space, it is not easily disturbed by the external environment, and dust and other debris in the external environment are not easy to fall between the protective layer and the substrate, thereby ensuring the lamination quality of the protective layer and the substrate.

[0076] Furthermore, the vacuum end of the vacuum assembly is connected to the first box body 51 or the second box body 52. ​​In this embodiment, the vacuum end of the vacuum assembly is connected to the second box body 52. ​​After the first box body 51 and the second box body 52 are buckled, the vacuum assembly is used to process the sealed space formed by the first box body 51 and the second box body 52 into a vacuum state. The protective layer and the substrate are attached in a vacuum state, and bubbles are not easily generated, thereby improving the attachment quality of the protective layer and the substrate. In this embodiment, the vacuum assembly includes a vacuum pump.

[0077] Reference Figure 1 and Figure 2 In this embodiment, the pressing module 3 further includes a deflection correction component 33 , and the deflection correction component 33 includes a rotary deflection correction driving component 331 and a horizontal deflection correction driving component 332 .

[0078] Reference Figure 1 and Figure 2 The driving end of the rotational deviation correction driving member 331 is connected to the pressing plate group 32. Specifically, the driving end of the rotational deviation correction driving member 331 is connected to the adsorption platform 321 to drive the pressing plate group 32 to rotate in a horizontal plane. In this embodiment, the rotational deviation correction driving member 331 includes a DD motor or a servo motor.

[0079] Reference Figure 1 and Figure 2 The horizontal deflection correction driving member 332 is installed on the frame 31, and the horizontal deflection correction driving member 332 is installed on the frame 31, and the rotary deflection correction driving member 331 is installed on the driving end of the horizontal deflection correction driving member 332. The rotary deflection correction driving member 331 and the pressing plate group 32 are driven by the horizontal deflection correction driving member 332 to move in a horizontal direction, and the driving direction of the horizontal deflection correction driving member 332 is perpendicular to the driving direction of the transposition module 4. In this embodiment, the horizontal deflection correction driving member 332 includes a linear motor or a screw mechanism.

[0080] In this arrangement, the pressing plate group 32 is driven to rotate on the horizontal plane by the rotation correction driving member 331, and the pressing plate group 32 is driven to move in the horizontal direction by the horizontal correction driving member 332, and at the same time, the position change module 4 can also adjust the position of the support module 2. Therefore, when the support module 2 is in the pressing position, the position of the pressing plate group 32 can be adjusted to ensure that the protective layer and the substrate are arranged vertically opposite to each other, and when the protective layer and the substrate are attached, the substrate and the protective layer are not easily misaligned, thereby ensuring the attachment quality.

[0081] Reference Figure 1 and Fig. 9 Furthermore, the protective layer vacuum bonding device also includes a visual detection component 6, which includes a mounting frame 61, an upward imaging module 62, a downward imaging module 63, a visual driving component 64 and a visual slide rail 65.

[0082] Reference Fig. 9 , the visual slide rail 65 is fixed on the machine base 1, and the mounting frame 61 is slidably arranged on the visual slide rail 65. The upward imaging module 62 and the downward imaging module 63 are both mounted on the mounting frame 61 to slide on the visual slide rail 65 along with the mounting frame 61. The visual driving component 64 is mounted on the visual slide rail 65, and the visual driving component 64 is drivingly connected to the mounting frame 61 to drive the mounting frame 61, the upward imaging module 62 and the downward imaging module 63 to slide on the visual slide rail 65. In this embodiment, the visual driving component 64 includes a screw mechanism or a linear motor.

[0083] Reference Figure 1 and Fig. 9 , the visual drive component 64 drives the mounting frame 61 to switch between the detection station and the avoidance station. Before the lamination operation, and after the support module 2 moves to the lamination station, the mounting frame 61, the upward imaging module 62 and the downward imaging module 63 move to the detection station. At this time, the mounting frame 61, the upward imaging module 62 and the downward imaging module 63 are located between the lamination plate group 32 and the support module 2. At this time, the upward imaging module 62 detects the position of the protective layer in the form of imaging, and it can know the position of the protective layer by identifying the corners of the protective layer or the marking points on the protective layer. The downward imaging module 63 detects the position of the substrate in the form of imaging, and it can know the position of the substrate by identifying the corners of the substrate or the marking points on the substrate.

[0084] After determining the positions of the substrate and the protective layer, the deviation correction component 33 is used to fine-tune the positions of the pressing plate group 32 and the protective layer, and the position change module 4 is used to fine-tune the positions of the support module 2 and the substrate to ensure that the substrate and the protective layer are aligned vertically, thereby improving the bonding quality of the protective layer and the substrate.

[0085] The positions of the substrate and the protective layer are automatically detected through imaging, so that during the bonding process of the protective layer and the substrate, the positions of the substrate and the protective layer can be determined more accurately and quickly, and the positions of the substrate and the protective layer can be fine-tuned more accurately.

[0086] In this embodiment, the upward-view imaging module 62 includes a plurality of cameras, and the downward-view imaging module 63 includes a plurality of cameras.

[0087] After the positions of the substrate and the protective layer are determined by the upward imaging module 62 and the downward imaging module 63, and the positions of the substrate and the protective layer are finely adjusted, the visual driver 64 drives the mounting frame 61 to move to the avoidance position, that is, the mounting frame 61, the upward imaging module 62 and the downward imaging module 63 are moved away from the pressing plate group 32 and the supporting module 2. At this time, the mounting frame 61, the upward imaging module 62 and the downward imaging module 63 do not interfere with the lifting movement of the substrate, and the bonding process of the substrate and the protective layer can be completed.

[0088] Reference Figure 1 and Fig. 9 Furthermore, in this embodiment, the driving direction of the visual driving member 64 is consistent with the driving direction of the transposition module 4, that is, the movement direction of the mounting frame 61 is consistent with that of the supporting module 2.

[0089] With this arrangement, the space occupied by the mounting frame 61 is the space above the supporting module 2, the space utilization of the entire bonding device is more reasonable, and the overall volume of the bonding device is smaller.

[0090] Reference Figure 1 and Figure 2 In this embodiment, the protective layer vacuum laminating device further includes a vacuum sealing component 5, and the vacuum sealing component 5 includes: a first box body 51, a second box body 52, a lifting drive member 53 and a vacuum pumping component.

[0091] Reference Figure 1 and Figure 2 The lifting drive member 53 is slidably mounted on the frame 31, and the lifting drive member 53 is connected to the driving end of the horizontal deviation correction drive member 332, and the lifting drive member 53 is driven by the horizontal deviation correction drive member 332 to move in the horizontal direction. The first box body 51 is mounted on the driving end of the lifting drive member 53, and the pressing plate group 32 is rotatably connected in the first box body 51, and the lower part of the first box body 51 is provided with an opening. In this embodiment, the lifting drive member 53 includes a screw mechanism, a cylinder or a linear motor.

[0092] Reference Figure 1 and Figure 2 The rotational deviation-correcting driving member 331 is installed on the driving end of the lifting driving member 53 , and the driving end of the rotational deviation-correcting driving member 331 extends into the first box body 51 and is drivingly connected to the pressing plate group 32 .

[0093] Reference Figure 1 and Figure 2 , the second box body 52 is slidably disposed on the base 1, the transposition module 4 is drivingly connected to the second box body 52 to drive the second box body 52 to slide on the base 1, the support module 2 is connected to the second box body 52 to slide with the second box body 52, and the support platform 21 is located in the second box body 52, and the second box body 52 is opened above. In this embodiment, the jacking assembly 22 is installed on the bottom surface of the second box body 52, and its driving end extends into the second box body 52 and is connected to the support platform 21. By placing the jacking assembly 22 outside the second box body 52, it is convenient to design the internal space of the second box body 52 to be smaller.

[0094] With this arrangement, when the substrate and the protective layer are pressed together, the lifting drive 53 first drives the first box 51 to descend, so that the first box 51 is buckled into the second box 52. At this time, the protective layer and the substrate are both located in the enclosed space formed by the first box 51 and the second box 52. Then, the lifting assembly 22 drives the support platform 21 to rise to achieve the lamination of the substrate and the protective layer. Since the lamination process of the substrate and the protective layer is carried out in a sealed space, it is not easily disturbed by the external environment, and dust and other debris in the external environment are not easy to fall between the protective layer and the substrate, thereby ensuring the lamination quality of the protective layer and the substrate.

[0095] In addition, after the support module 2 and the second box body 52 are moved to the pressing station, the positions of the substrate and the protective layer are corrected by the correction component 33. Since both the first box body 51 and the second box body 52 have thick walls, the first box body 51 and the second box body 52 can still be sealed and buckled.

[0096] Furthermore, the vacuum end of the vacuum assembly is connected to the first box body 51 or the second box body 52. ​​In this embodiment, the vacuum end of the vacuum assembly is connected to the second box body 52. ​​After the first box body 51 and the second box body 52 are buckled, the vacuum assembly is used to process the sealed space formed by the first box body 51 and the second box body 52 into a vacuum state. The protective layer and the substrate are attached in a vacuum state, and bubbles are not easily generated, thereby improving the attachment quality of the protective layer and the substrate. In this embodiment, the vacuum assembly includes a vacuum pump.

[0097] In this embodiment, the lamination process of the protective layer and the substrate is as follows:

[0098] The support module 2 is located at the loading station, and the substrate is loaded onto the support table 21, and the protective layer is loaded under the pressing plate group 32. The loading of the protective layer and the substrate can be achieved by a manipulator. The transposition module 4 transfers the support module 2 to the pressing station. Subsequently, the visual driver 64 drives the mounting frame 61, the upward imaging module 62 and the downward imaging module 63 to move to the detection station. After determining the position of the substrate and the protective layer, the correction component 33 and the transposition module 4 are used to change the position of the protective layer and the substrate so that the protective layer and the substrate are facing each other up and down. The visual driver 64 then transfers the mounting frame 61, the upward imaging module 62 and the downward imaging module 63 to the avoidance station. Subsequently, the lifting driver 53 drives the first box 51, the pressing plate group 32 and the protective layer to descend, so that the first box 51 and the second box 52 are buckled, and the vacuum assembly is started to make the first box 51 and the second box 52 in a vacuum state. The lifting assembly 22 drives the support platform 21 and the substrate to rise to achieve the bonding of the substrate and the protective layer. After the bonding of the substrate and the protective layer is completed, the adsorption platform 321 of the pressing plate group 32 stops working and releases the adsorption of the protective layer. Subsequently, the first box 51 and the pressing plate group 32 are lifted up, and the second box 52 and the support module 2 as well as the bonded substrate and the protective layer are moved to the loading station to take away the bonded finished product, and then the next round of bonding processing can be carried out.

[0099] The embodiment of the present application provides a protective layer vacuum bonding device. When the bonding device is working, the support module 2 is first in the loading station, and the substrate is placed on the support table 21, and the protective layer can be loaded to the bottom surface of the arc-shaped elastic plate 322 at the same time, and the protective layer is adsorbed and fixed. Then the transposition module 4 drives the support module 2 to move to the pressing station, at which time the protective layer and the substrate are arranged vertically opposite each other. The lifting assembly 22 drives the support table 21 and the substrate to rise, first contacting the middle part of the protective layer, and as the substrate further rises, the arc-shaped elastic plate 322 is squeezed, and the arc-shaped elastic plate 322 gradually deforms into a flat plate, and the protective layer gradually contacts the substrate from the middle to the edge. Finally, since the arc-shaped elastic plate 322 is flat on the adsorption platform 321, the arc-shaped elastic plate 322 is in a flat shape, which uniformly presses the substrate and the protective layer to achieve bonding between the substrate and the protective layer. Due to the arrangement of the arc-shaped elastic plate 322, the protective layer gradually adheres to the substrate from the middle to the edge. During the bonding process of the protective layer and the substrate, bubbles are less likely to be generated between the protective layer and the substrate, thereby improving the bonding quality of the protective layer and the substrate.
