Description

Technical Field

[0001] The present invention belongs to the technical field of film laminating machines, and in particular, relates to a 3D curved glass film laminating machine. Background Art

[0002] Mobile phone products are constantly being updated, and the display screen has evolved from the previous single flat shape to the current 2.5D and 3D mobile phone screens. With the expansion of the application range of curved glass, the production efficiency of products needs to be continuously improved to meet the needs of the market. In the past, the mobile phone screen glass cover was flat, and only one station of rolling and pressing could be used to implement the film application. When 3D mobile phone covers appeared, it became a difficult problem to implement the film application at one station, or to implement the film application at one station more efficiently.

[0003] If we want to improve efficiency and film quality, we need to develop new film laminating equipment to meet the film laminating needs of new products. Existing film laminating machines are mainly used for flat surfaces. The use of contoured roller laminating can achieve product laminating when the two curves are less than 90°. However, due to the special structure of the new products with two curves greater than 90°, there is currently no equipment that can meet the requirements of automated production. The main difficulty is that the two curves greater than 90° are inward-buckled and have a small inner radius. Traditional roller film laminating cannot achieve small curvature inner laminating. Even if the curvature can meet the roller laminating requirements, multiple stations are required to complete the front film laminating and the effect is not ideal.

[0004] At present, manual processing and installation are mostly used to complete the film pasting work. The manual method has the disadvantages of being time-consuming and labor-intensive, high investment cost and unstable film pasting quality. Summary of the invention

[0072] Example 1

[0073] In this embodiment, a 3D curved glass laminating machine is specifically provided, which aims to optimize the structure of the laminating machine so as to perform good laminating on products with two curves greater than 90°, and at the same time, improve the efficiency of the entire laminating process.

[0074] like Figure 1 , Figure 2 As shown, the laminating machine of this embodiment mainly includes a convex laminating mechanism, a concave laminating mechanism and a flipping mechanism, which together constitute the main body of the laminating machine. When the laminating machine designed in this embodiment is working, it first performs convex laminating, and then transfers and flips by the flipping mechanism, and then performs concave laminating. The specific design is as follows:

[0075] (1) Convex film laminating mechanism

[0076] like Figure 3-Figure 8As shown, the convex film-laminating mechanism includes a convex bearing portion 36, convex side pressure portions located on both sides of the convex bearing portion 36, and a convex flat pressing portion located above the convex bearing portion 36. The convex flat pressing portion is provided with a driving member A 4 for driving its lifting movement, and the convex flat pressing portion is linked to the convex side pressure portion to make corresponding movements, and the convex film-laminating on the workpiece 21 is achieved through the joint linkage movement of the convex flat pressing portion and the convex side pressure portion, so as to perfectly solve the problem of film-laminating on the convex side surface of the product with two curves greater than 90°.

[0077] Design for convex bearing part 36

[0078] The convex surface bearing part 36 includes a convex surface film-sticking table 23, the lower part of which is mounted on the machine tool body 1 through a bracket 12. A convex surface fixture matching the workpiece 21 is provided on the convex surface film-sticking table 23 to achieve adsorption and fixation of the workpiece 21 to prevent displacement of the workpiece 21 during the film-sticking process.

[0079] Specifically, the convex jig includes: a convex jig main body and convex jig side bodies 20 slidably arranged on both sides of the convex jig main body, the convex jig main body matches the convex plane of the workpiece 21, and a plurality of adsorption pores are arranged on the convex jig main body, and the workpiece 21 is strongly adsorbed and fixed by the negative pressure formed by each adsorption pore; the convex jig side bodies 20 match the inner curved surface of the workpiece 21, and the convex jig side bodies 20 are provided with limiting members for limiting the position thereof, and since the convex jig side bodies 20 can slide relative to the convex jig main body, the convex jig can adapt to workpieces 21 of different sizes, and the convex jig side bodies 20 on both sides only need to be slid to the appropriate position, and the convex jig side bodies 20 are limited by the limiting members to meet the requirements of carrying workpieces 21 of different sizes. Among them, in actual application, the limiter includes a limit seat arranged below the convex film-sticking table 23 and a slide rod slidably arranged on the limit seat, the slide rod is connected to the convex jig side body 20 and is located in the sliding direction of the convex jig side body 20, and the slide rod is connected to the A cylinder 13 that drives it to move. Under the action of the A cylinder 13, the convex jig side bodies 20 on both sides are driven to move relative to or away from each other, so as to adapt to workpieces 21 of different sizes, and cooperate with the convex jig body to stably adsorb and fix the workpiece 21, so as to ensure the smooth progress of the subsequent convex film-sticking process.

[0080] Of course, the use of a cylinder to drive the convex jig side bodies 20 on both sides is only a preferred solution of this embodiment. In order to save costs, a manual method can also be used. A locking screw is connected to the convex jig side body 20. When a film is applied to a certain workpiece 21, the convex jig side body 20 is adjusted to an appropriate position and then locked by the locking screw.

[0081] Design of convex side pressure part

[0082] Convex side pressure parts are provided on both sides of the convex fixture. In actual application, the convex side pressure parts include linkage side pressure blocks 16 slidably arranged on both sides of the convex film-sticking table 23. The linkage side pressure blocks 16 are equipped with reset members 17 for driving them to reset. Preferably, a spring is used as the reset member 17. Under the action of the reset member 17, when the linkage side pressure blocks 16 are displaced to apply film to the convex side surface of the workpiece 21, they can be reset to their original positions.

[0083] Design of convex flat part

[0084] The convex flattening part includes a convex flattening body 19 and a convex side pressure body 14 sleeved on the outside of the convex flattening body 19. The convex side pressure body 14 is set in a "concave" frame shape. The convex side pressure body 14 is connected to the A driving member 4. Under the action of the A driving member 4, it is driven to move up and down. The side arms of the convex side pressure body 14 are provided with active side pressure blocks 15 and convex side pressure blocks 18. The convex side pressure blocks 18 are slidably arranged on the side of the convex side pressure body 14 and are provided with convex pressure ports that match the outer curved surface of the workpiece 21. The sliding direction of the convex side pressure block 18 is parallel to the direction of the plane of the workpiece 21. In actual application, its movement process is as follows:

[0085] Under the action of the A driving member 4, the convex side pressure body 14 is driven to perform a downward pressing movement. During the downward pressing movement, the active side pressure block 15 contacts the linkage side pressure block 16, and the linkage side pressure block 16 is driven to slide by the downward movement of the active side pressure block 15. As the linkage side pressure block 16 moves, it will gradually abut against the convex side pressure block 18, and then the sliding of the linkage side pressure block 16 pushes the convex side pressure block 18 to slide. The side of the convex side pressure block 18 is provided with a convex pressure opening that matches the outer curved surface of the workpiece 21. Under the action of the convex pressure opening, the film material can be tightly attached to the surface of the workpiece 21. In actual application, in order to ensure the mutual movement between the active side pressure block 15, the linkage side pressure block 16 and the convex side pressure block 18, the active side pressure block 15 and the linkage side pressure block 16, and the linkage side pressure block 16 and the convex side pressure block 18 are all set as inclined matching surfaces, so as to drive the linkage movement under the action of the inclined matching surfaces.

[0086] In actual application, for the design of A driving component 4, a three-axis manipulator is adopted as A driving component 4. Under the action of the three-axis manipulator, in addition to satisfying the driving of the downward pressing action, the entire convex flat pressing part can also be driven to move to the corresponding position of the film tearing table in the feeding mechanism, thereby completing the film tearing action of the film material.

[0087] (2) Concave film sticking mechanism

[0088] like Figure 9-13As shown, the concave film-laminating mechanism includes a concave bearing portion 38 and a concave flat pressing portion located above the concave bearing portion 38. The concave flat pressing portion is equipped with a B driving member 5 for driving it to perform lifting motion and a C driving member for performing outward expansion motion. The concave film is laminating on the workpiece 21 through the lifting motion and outward expansion motion of the concave flat pressing portion, so as to perfectly solve the problem of film laminating on the concave side surface of the product with two curves greater than 90°.

[0089] Design of the concave bearing portion 38

[0090] The concave bearing portion 38 includes a concave film-sticking table 24, which is installed on the machine tool through a bracket 12. The concave film-sticking table 24 is provided with a concave fixture matching the workpiece 21. The concave fixture also realizes the adsorption and fixation of the workpiece 21 to prevent the workpiece 21 from displacement during the film-sticking process.

[0091] Specifically, the concave jig includes: a concave jig main body and a concave jig side body 28 which is slidably arranged on the concave jig main body and symmetrically arranged, wherein the concave jig main body is arranged on the concave film sticking table 24, and at the same time, the concave jig side body 28 is slidably arranged on the concave jig main body and is symmetrically and synchronously slidably arranged, and the concave jig side body 28 matches the outer curved surface of the workpiece 21, and a plurality of adsorption air holes are provided on each of the concave jig side bodies 28, and negative pressure is formed through each adsorption air hole to stabilize the workpiece 21 on the concave jig. The concave jig side body 28 is provided with a limiting piece for limiting its position. Since the concave jig side body 28 can slide relative to the concave jig main body, the concave jig can adapt to workpieces 21 of different sizes. It only needs to slide the concave jig side bodies 28 on both sides to the appropriate position and limit the concave jig side bodies 28 by the limiting piece to meet the requirements of carrying workpieces 21 of different sizes. In actual application, the limit member includes a limit seat provided on the concave film-sticking platform 24 and a slide rod slidably provided on the limit seat, the slide rod is connected to the concave jig side body 28 and is located in the sliding direction of the concave jig side body 28, and the slide rod is connected to a B cylinder 25 for driving its movement, and under the action of the B cylinder 25, the concave jig side bodies 28 on both sides are driven to move relative to or away from each other, so as to adapt to workpieces 21 of different sizes, and cooperate with a plurality of adsorption holes provided on the concave jig side body 28 to stably adsorb and fix the workpiece 21 to ensure the smooth progress of the subsequent concave film-sticking process. Of course, the use of a cylinder to drive the concave jig side bodies 28 on both sides is only the preferred solution of this embodiment. In order to save costs, a manual method can also be used. A locking screw is connected to the concave jig side body 28. When a film is applied to a certain workpiece 21, the concave jig side body 28 is adjusted to an appropriate position and then locked by the locking screw.

[0092] Design of concave flat pressing part

[0093] The concave surface pressing part comprises: a concave surface pressing body, which is connected to the B driving member 5 , and the concave surface pressing body is pressed downward under the action of the B driving member 5 .

[0094] Two concave side pressing blocks 26 are slidably arranged on the concave flat pressing body, and the two concave side pressing blocks 26 are symmetrically arranged, so that the concave side pressing blocks 26 on both sides can move synchronously relative to or synchronously opposite to each other to adapt to different sizes of workpieces 21 and can press and adhere the inner concave side of the workpiece 21.

[0095] Each of the concave side pressure blocks 26 is connected to a C driving member that drives it to slide. Under the action of the C driving member, the concave side pressure blocks 26 on both sides can be driven to expand outward, and each of the concave side pressure blocks 26 matches the inner concave surface of the workpiece 21 to complete the smooth film application on the inner concave side of the workpiece 21. In actual application, the C driving member adopts a C cylinder 27, and the piston rod of the C cylinder 27 pushes the concave side pressure blocks 26 to expand outward through a push rod.

[0096] (3) Flipping mechanism

[0097] like Figure 14-16 As shown, the flipping mechanism serves as a transfer component between the convex film laminating station 9 and the concave film laminating station 11. In this embodiment, the workpiece 21 is transferred from the convex film laminating station to the concave film laminating station through the flipping mechanism (or according to the design of the convex film laminating station 9 and the concave film laminating station 22, it is transferred from the concave film laminating station to the convex film laminating station through the flipping mechanism), and the workpiece 21 in the current state is flipped 180° during the transfer, thereby ensuring the smooth completion of the entire film laminating process of the workpiece 21.

[0098] The flipping mechanism includes: a transfer bearing part 37, a transport part and a material moving part arranged between the convex bearing part 36 and the concave bearing part 38; the convex bearing part 36, the transfer bearing part 37 and the concave bearing part 38 are arranged in sequence on the machine tool body 1 along the same straight line direction, and the workpiece 21 is transferred and flipped between the convex bearing part 36 and the transfer bearing part 37 or between the concave bearing part 38 and the transfer bearing part 37 through the transport part; the workpiece 21 is transferred between the convex bearing part 36 and the transfer bearing part 37 or between the concave bearing part 38 and the transfer bearing part 37 through the material moving part.

[0099] In actual application, a D driving member 29 is provided on the machine tool body 1, and the D driving member 29 drives the transfer part and the material transfer part to perform synchronous displacement movement. Preferably, the D driving member 29 includes a drive seat 30 and a screw nut pair that drives the drive seat 30 to move, and the screw nut pair is equipped with a motor that drives it to rotate, and the transfer part and the material transfer part are both installed on the drive seat 30, and it is ensured that the transfer part and the material transfer part correspond to the convex bearing part 36 and the transfer bearing part 37 respectively. At the same time, when the drive seat 30 moves, the transfer part and the material transfer part can correspond to the transfer bearing part 37 and the concave bearing part 38 respectively.

[0100] For the design of the transfer part, the transfer part includes: a transfer bracket 31 arranged on the D driving member 29 and a lifting cylinder arranged on the transfer bracket 31, a rotating part 35 is installed on the lifting cylinder, the rotating part 35 is connected to the transfer arm 33 and the transfer arm 33 is provided with an adsorption air nozzle, preferably, the rotating part 35 can adopt a pneumatic rotary pump. During operation, the lifting cylinder drives the rotating part 35 and the transfer arm 33 to descend or rise, adsorb the workpiece 21 under the action of the adsorption air nozzle, and realizes 180° flipping of the workpiece 21 under the action of the rotating part 35, and finally transfers the workpiece 21 from the current station to the next station under the action of the D driving member 29. At the same time, in order to ensure that the transfer arm 33 will not be interfered by the transfer bearing part 37 when rotating, a notch is provided on the transfer bearing part 37 to realize the state of the workpiece 21 to be flipped 180° after the transfer arm 33 is rotated.

[0101] As for the design of the material transfer part, the material transfer part includes: a material transfer bracket 32 ​​provided on the D driving member 29 and a lifting cylinder provided on the material transfer bracket 32, wherein a material transfer arm 34 is mounted on the lifting cylinder, and a suction nozzle is provided on the material transfer arm 34. During operation, the lifting cylinder realizes the rise or fall of the material transfer arm 34, and at the same time, with the cooperation of the suction nozzle on the material transfer arm 34, the workpiece 21 can be adsorbed, and finally, with the cooperation of the D driving member 29, the workpiece 21 is transferred from the current station to the next station.

[0102] Based on the above, when the flip mechanism is in operation, its working principle is as follows:

[0103] When the convex film laminating station 9 completes the film laminating on the workpiece 21, the transfer unit moves to the convex film laminating station 9, and moves the workpiece 21 on which the convex film laminating station 9 has been completed to the transfer carrying portion 37, and the transfer unit flips the workpiece 21 and places it on the transfer carrying portion 37; at the same time, when the transfer unit moves to the convex film laminating station 9, the material transfer unit just corresponds to the transfer carrying portion 37, and the material transfer unit absorbs the workpiece 21 that has been flipped in the previous process, and after the transfer unit moves to the transfer carrying portion 37, the material transfer unit also synchronously runs to the concave film laminating station 11, and the material transfer unit places the workpiece 21 on the concave film laminating station 11, thereby completing the entire film laminating process for the workpiece 21 in a cycle.

[0104] (4) Film feeding mechanism

[0105] In order to ensure the smooth completion of convex film laminating and concave film laminating, when the film laminating machine is working, film feeding mechanisms corresponding to the convex film laminating mechanism and the concave film laminating mechanism need to be provided, and the film 22 is supplied to the convex film laminating mechanism and the concave film laminating mechanism respectively through the film feeding mechanisms. The design of the film feeding mechanism is as follows:

[0106] The film feeding mechanism includes: a loading tray 6, a receiving tray 7, a plurality of feeding rods 8 arranged between the loading tray 6 and the receiving tray 7, and a film tearing table for carrying the film material strip. The loading tray 6 and the receiving tray 7 are rotatably arranged on the machine tool body respectively. At the same time, the receiving tray 7 is equipped with a power source for driving its rotation. The power source can be driven by a motor + belt to realize the rotation of the receiving tray 7.

[0107] During operation, a film tape is wound on the loading tray 6, and each of the feeding rods 8 is in tension with the film tape, so that the film tape is finally wound on the receiving tray 7. When the receiving tray 7 rotates, it can drive the movement of the entire film tape, thereby realizing the feeding of the film tape. During the feeding process of the film tape, it will pass through the film tearing table, and the convex flat pressing part or the concave flat pressing part will tear the film by pressing down the film tape on the film tearing table. For the design of the film tape, a more conventional method can be adopted. The film tape is pre-divided into the film sticker 22 to be used according to the size of the workpiece 21. When the convex flat pressing part or the concave flat pressing part is pressed down and tightly attached to the film sticker 22, since the convex flat pressing part and the concave flat pressing part are both provided with a plurality of adsorption pores, the film sticker 22 is tightly adsorbed. When the convex flat pressing part or the concave flat pressing part is lifted, the film sticker 22 can be separated from the film tape, thereby completing the entire film tearing action.

[0108] The film laminating machine provided in this embodiment has the following operation process when the whole machine is working:

[0109] First, the film material raw material is loaded into the tray loading station, and the film material is discharged from the feeding station to the receiving station to complete the film material loading action; then the material tray 2 is placed on the assembly line, and the material tray 2 is loaded with the product (glass cover); then the X / Y / Z axis manipulator grabs the workpiece 21 product of the material tray 2 on the assembly line to the convex film laminating station 9;

[0110] The loading station and the receiving station work together to complete the movement of the film material; at the film tearing station 3, the used film material is adsorbed to the film tearing section station by vacuum adsorption, and then transferred to the top of the convex film sticking station by the action of the A driving member 4, and then pressed down to complete the film sticking; after the convex film section sticks the film, it is moved to the concave film section sticking station by the action of the flip mechanism; the concave film station also transfers the film material through the film tearing section station, and the film pressing is realized by the joint action mechanism of the B driving member 5 and the C driving member;

[0111] After the film is applied, the film-applied product is transferred to the material tray 2 on the assembly line by the X / Y / Z axis robot.

[0112] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
