Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal screen manufacturing, in particular to an automatic film laminating machine for liquid crystal screen ICs. Background Art

[0002] As liquid crystal display devices become thinner and lighter, mounting IC chips directly on glass substrates has become the mainstream process. To prevent the IC from being scratched by hard objects during production and transportation, a protective film must be applied to the surface.

[0003] like Figure 1 As shown, the protective film adopts the "double upper film with the same lower film" structure, that is, two protective films a are attached side by side on the same lower film b, and each protective film a is covered with an independent upper film c. The upper film c is longer than the protective film a but shorter than the lower film b. When applying the film, you need to tear off the film b first, then apply the protective film a separately, and finally tear off the film c.

[0004] For this type of protective film with a "double upper film and lower film" structure, the following problems currently exist in film application:

[0005] 1. Manual film lamination requires multiple film tearing / alignment, which is labor-intensive, time-consuming and labor-intensive, and has low operating efficiency. In addition, manual visual alignment can easily cause the position of the protective film and the IC to shift, resulting in low precision, and manual operation can easily cause IC surface contamination.

[0006] 2. Although there are film-laminating equipment on the market, they only support the independent attachment of a single film and cannot adapt to the structure of "double upper film and lower film".

[0052] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] Attachment Figure 2-12 The automatic film laminating machine for LCD screen IC of the present invention comprises a machine platform 1, a turntable unit 2, a film supply unit 3, a film supply robot 4, a correction unit 5, a film laminating robot 6, a film tearing unit 7, a detection unit 8 and a pressing unit 9 respectively arranged on the machine platform 1;

[0054] The turntable unit 2 includes a turntable 21 horizontally arranged on the machine 1 and driven by an intermittent divider, a loading station 22, a film laminating station 23, a pressing station 24 and a unloading station 25 respectively arranged at the edge of the turntable 21, and a fixture 26 respectively arranged at each station for fixing the product 10;

[0055] The film supply unit 3 includes at least one silo 31 for stacking protective films;

[0056] The film supply robot 4 is used to suck the protective films piece by piece from the silo 31 and place them on the correction unit 5;

[0057] The correction unit 5 is used to correct the position of the protective film;

[0058] The film-applying robot 6 includes a robot arm 61 and a material suction assembly 62 provided at the driving end of the robot arm 61; the material suction assembly 62 has two independently liftable long strip suction cups 621, each for sucking two upper films c on the same lower film b; the robot arm 61 drives the material suction assembly 62 to first suck the calibrated protective film from the calibration unit 5 and send it to the film tearing unit 7 to tear off the film b, then send it to the inspection unit 8 for inspection, and finally install it on the product IC of the film-applying station 23 in two steps, and tear off the upper film c from the protective film a after each film application;

[0059] The film tearing unit 7 includes a bracket and a clamping cylinder 71 provided on the bracket; the clamping cylinder 71 cooperates with the film sticking robot 6 to tear off the lower film b;

[0060] The detection unit 8 is located at the film laminating station 23 and includes an upper visual component 81 facing vertically downward for detecting the position of the product IC in the film laminating station 23 and a lower visual component 82 facing vertically upward for detecting the position of the protective film a at the driving end of the film laminating robot 6;

[0061] The pressing unit 9 is located at the pressing station 24 and is used to flatten the protective film a attached to the product IC position.

[0062] During operation: the upstream production line automatically places the product 10 on the loading station 22 and fixes it with a jig 26; then the intermittent divider drives the turntable 21 to rotate 90 degrees, and sends the product 10 to the film-applying station 23 to apply the protective film a; then the intermittent divider drives the turntable 21 to rotate 90 degrees again, and sends the product 10 with the film applied to the pressing station 24, and the protective film a is flattened by the pressing unit 9; finally, the intermittent divider drives the turntable 21 to rotate 90 degrees again, and sends it to the unloading station 25, the jig 26 releases the product 10, and the downstream production line automatically takes the material from the unloading station 25 for subsequent production.

[0063] The specific film laminating process is as follows: the film supply robot 4 picks up the protective films piece by piece from the hopper 31 and places them in the calibration unit 5 for position calibration, so that the protective films grabbed by the film laminating robot 6 are located at the same position each time;

[0064] Then the film-applying robot 6 drives the suction assembly 62 through the robot arm 61 to first suck the calibrated protective film from the calibration unit 5. At this time, the two long suction cups 621 respectively suck the upper film c on the surface of the two protective films a on the same lower film b;

[0065] Then the robot arm 61 drives the suction assembly 62 to the film tearing unit 7 to tear off the film b. Specifically, the gripper cylinder 71 clamps the extended part of the lower film b (taking advantage of the fact that the upper film c is shorter than the lower film b) and cooperates with the film-applying robot 6 to complete the film tearing. At this time, the two long suction cups 621 still respectively suck the two pieces of upper film c;

[0066] Then the robot arm 61 drives the suction component 62 to send it to the detection unit 8 for inspection. Specifically, the lower visual component 82 detects the position of the protective film a at the driving end of the film-applying robot 6, while the upper visual component 81 detects the position of the product IC in the film-applying station 23, so as to facilitate accurate alignment during film-applying and improve film-applying accuracy.

[0067] Finally, the protective film a is applied to the product IC at the film application station 23 twice, and the upper film c is torn off from the protective film a after each application.

[0068] Further, if Figure 5 As shown, each of the long strip suction cups 621 is divided into two separate areas, namely the overlapping area 6211 for adsorbing the overlapping part of the upper film c and the protective film a, and the single area 6212 for adsorbing only the part of the upper film c extending out of the protective film a. This design is specially adapted to the incoming material form of "double upper films c and a common lower film b", solving the problem of synchronous film tearing; when tearing off the film, the overlapping area 6211 and the single area 6212 can be adsorbed at the same time, so as to achieve the effect of accurately tearing off the lower film b without damaging the protective film a; when tearing off the upper film c, only the single area 6212 is adsorbed to avoid displacement of the protective film a, thereby realizing step-by-step film tearing.

[0069] Further, if Figure 4 As shown, the suction assembly 62 includes a suction cup frame 622 and two staggered cylinders 623 vertically arranged in the suction cup frame 622; the tops of the two elongated suction cups 621 are each provided with a mounting portion 624; the two mounting portions 624 are located between the two staggered cylinders 623, not only spaced apart but also connected to the driving ends of the two staggered cylinders 623 respectively;

[0070] During the process of sucking the protective film from the correction unit 5 and tearing off the film b, the two staggered cylinders 623 are in a retracted state; when the film needs to be applied, one of the staggered cylinders 623 extends to drive the long strip suction cup 621 to descend, so that the two long strip suction cups 621 are not in the same plane, which facilitates the application of the protective film a to the product IC.

[0071] Further, if Figure 7 As shown, the film tearing unit 7 also includes a waste vacuum collector located in the machine 1; the collection port 72 of the waste vacuum collector is located below the clamping cylinder 71; when the clamping cylinder 71 releases the lower film b, the waste can be directly collected through the waste vacuum collector; at the same time, the upper film c torn off by the film-sticking robot 6 is also sent to the waste vacuum collector for waste collection.

[0072] Further, if Figure 8 As shown, the correction unit 5 includes a correction seat 51, a correction platform 52 horizontally arranged above the correction seat 51, a plurality of vertically placed columns 53 for connecting the correction seat 51 and the correction platform 52, a positioning groove provided on the top of the correction platform 52 for placing a protective film, notches 54 respectively provided on the correction platform 52 and located on the sides and ends of the positioning groove, an end positioning component provided on the correction seat 51 for positioning the protective film in the positioning groove in the length direction, and a side positioning component provided on the correction seat 51 for positioning the protective film in the positioning groove in the width direction;

[0073] The correction seat 51 has two notches 54 on the side and only one notch 54 on the end.

[0076] During correction: the side positioning assembly and the end positioning assembly act simultaneously, and the correction positioning is achieved through the other two right-angled sides of the positioning groove; specifically: since the two protective films are located on the same lower mold, the side positioning cylinder 55 drives the side positioning seat 56 to drive the two side positioning columns 57 to press against the side surfaces of the lower film b respectively, and the end positioning cylinder 58 directly drives the end positioning column 59 to press against the end of the lower film b to achieve the positioning of the protective film.
