Description

Technical Field

[0001] This utility model relates to the field of liquid crystal screen manufacturing technology, and specifically to an automatic liquid crystal screen IC film application machine. Background Technology

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

[0003] like Figure 1 As shown, the protective film adopts a "double upper film and same lower film" material supply method, that is, two protective films a are attached side by side to the same lower film b, and each protective film a is covered with an independent upper film c, wherein the upper film c is longer than the protective film a but shorter than the lower film b; when applying the film, film b needs to be peeled off first, then the protective films a are applied separately, and finally the upper film c is peeled off.

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

[0005] 1. Manual film application requires multiple film peeling / alignment, which is labor-intensive, time-consuming, and inefficient. Furthermore, manual visual alignment can easily lead to misalignment between the protective film and the IC, resulting in low precision. In addition, manual operation can easily cause contamination of the IC surface.

[0006] 2. Although there are film application machines on the market, they only support single-film independent application and cannot adapt to the structure of "double upper film and same lower film". The film still needs to be pre-peeled manually, resulting in low automation. Utility Model Content

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

[0053] Appendix Figure 2-12The automatic LCD screen IC film applicator of this utility model includes a machine base 1, a turntable unit 2, a film supply unit 3, a film supply robot 4, a calibration unit 5, a film applicator robot 6, a film peeling unit 7, a detection unit 8, and a pressing unit 9, all respectively arranged on the machine base 1.

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

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

[0056] The film supply robot 4 is used to pick up protective films one by one from the hopper 31 and place them on the calibration 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 robotic arm 61 and a suction component 62 disposed at the drive end of the robotic arm 61. The suction component 62 has two elongated suction cups 621 that can be lifted and lowered independently, which are used to pick up two upper films c on the same lower film b. The robotic arm 61 drives the suction component 62 to first pick up the corrected protective film from the correction unit 5 and send it to the film-tearing unit 7 to tear off the film b, then send it to the detection unit 8 for detection, and finally install it onto the product IC at the film-applying station 23 in two stages, 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 gripper cylinder 71 mounted on the bracket; the gripper cylinder 71 and the film-applying robot 6 work together to tear off the lower film b.

[0060] The detection unit 8 is located at the film application station 23 and includes an upper vision component 81 that is vertically downward for detecting the position of the product IC in the film application station 23 and a lower vision component 82 that is vertically upward for detecting the position of the protective film a at the drive end of the film application robot 6.

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

[0062] During operation: The upstream production line automatically places product 10 on the loading station 22 and fixes it with fixture 26; then the intermittent divider drives the turntable 21 to rotate 90 degrees, sending product 10 to the film application station 23 to apply protective film a; then the intermittent divider drives the turntable 21 to rotate 90 degrees again, sending the film-applied product 10 to the pressing station 24, where the pressing unit 9 flattens the protective film a; finally, the intermittent divider drives the turntable 21 to rotate 90 degrees again, sending it to the unloading station 25, where fixture 26 releases product 10, and the downstream production line automatically picks up the material from the unloading station 25 for subsequent production.

[0063] The specific film application process is as follows: the film supply robot 4 picks up the protective film piece by piece from the material bin 31 and places it in the calibration unit 5 for position calibration, so that the protective film picked up by the film application robot 6 each time is in the same position;

[0064] Then, the film-applying robot 6 drives the suction component 62 through the robotic arm 61 to first pick up the corrected protective film from the correction unit 5. At this time, the two long strip suction cups 621 respectively pick up the upper film c on the surface of the two protective films a on the same lower film b.

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

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

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

[0068] Furthermore, such as Figure 5 As shown, each of the elongated suction cups 621 is divided into two separate areas: an overlapping area 6211 that adsorbs the overlapping portion of the upper film c and the protective film a, and a single area 6212 that only adsorbs the portion of the upper film c extending beyond the protective film a. This design is specifically adapted to the "double upper film c and common lower film b" feeding format, solving the problem of simultaneous film tearing. When tearing off the film, the overlapping area 6211 and the single area 6212 can be adsorbed simultaneously, achieving 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, avoiding displacement of the protective film a, thereby realizing step-by-step film tearing.

[0069] Furthermore, such as Figure 4As shown, the suction assembly 62 includes a suction cup frame 622 and two staggered cylinders 623 vertically arranged inside the suction cup frame 622; the top of each of the two elongated suction cups 621 has a mounting part 624; the two mounting parts 624 are located between the two staggered cylinders 623, and are not only placed at intervals, but are also connected to the driving end of the two staggered cylinders 623 respectively.

[0070] During the process of picking up the protective film from the calibration unit 5 and peeling off the film b, both staggered cylinders 623 are in the retracted state; when the film needs to be applied, one of the staggered cylinders 623 extends and drives the elongated suction cup 621 to descend, so that the two elongated suction cups 621 are not on the same plane, making it easier to apply the protective film a to the product IC.

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

[0072] Furthermore, such as Figure 8 As shown, the calibration unit 5 includes a calibration seat 51, a calibration platform 52 horizontally arranged above the calibration seat 51, multiple vertically placed columns 53 for connecting the calibration seat 51 and the calibration platform 52, a positioning groove on the top of the calibration platform 52 for placing the protective film, notches 54 respectively arranged on the calibration platform 52 and located on the side and end of the positioning groove, an end positioning component arranged on the calibration seat 51 for positioning the protective film in the positioning groove in the length direction, and a side positioning component arranged on the calibration seat 51 for positioning the protective film in the positioning groove in the width direction.

[0073] The calibration seat 51 has two notches 54 on its side and only one notch 54 at its end;

[0074] The side positioning assembly includes a side positioning cylinder 55 disposed on the calibration seat 51 and placed along the width direction of the protective film, a side positioning seat 56 disposed at the drive end of the side positioning cylinder 55, and a side positioning post 57 disposed on the side positioning seat 56 and located in the side notch 54 of the calibration seat 51.

[0075] The end positioning assembly includes an end positioning cylinder 58 disposed on the calibration seat 51 and placed along the length of the protective film, and an end positioning post 59 disposed at the drive end of the end positioning cylinder 58 and located in the end notch 54 of the calibration seat 51.

[0076] During calibration: the side positioning component and the end positioning component operate simultaneously, and calibration and positioning are 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 pins 57 to abut against the side of the lower film b respectively, while the end positioning cylinder 58 directly drives the end positioning pin 59 to abut against the end of the lower film b, thereby achieving the positioning of the protective film.

[0077] Furthermore, such as Figure 7 As shown, there are two hoppers 31. When one hopper 31 is supplying material, the other hopper 31 can be replenished, so as to achieve non-stop operation.

[0078] Furthermore, such as Figure 9 As shown, the material bin 31 is provided with U-shaped grooves 32 placed on opposite sides, which makes it easier to move the material bin 31 away from the film supply robot 4 for replenishment, making it safer.

[0079] Furthermore, such as Figure 9 As shown, the two material bins 31 are respectively mounted on the slide rail assembly 33, which facilitates moving the material bins 31 away from the film supply robot 4 for replenishment.

[0080] Furthermore, such as Figure 9 As shown, a handle 34 is provided on the outer side of the hopper 31 to facilitate moving the hopper 31 by means of the handle 34.

[0081] Furthermore, such as Figure 7 As shown, the film supply robot 4 includes a frame 41, an X-axis linear module 42 horizontally arranged on the frame 41, a Z-axis linear module 43 vertically arranged at the drive end of the X-axis linear module 42, a mounting base 44 arranged at the drive end of the Z-axis linear module 43, and two vacuum suction tubes 45 arranged vertically and side by side on the mounting base 44.

[0083] The length of the vacuum suction tube 45 is greater than the depth of the hopper 31;

[0084] During operation: With the joint cooperation of the X-axis linear module 42 and the Z-axis linear module 43, the drive mounting base 44 drives the two vacuum suction tubes 45 to pick up the protective film from one of the hoppers 31 and place it into the positioning groove of the calibration unit 5.

[0085] Furthermore, such as Figure 10As shown, the upper vision component 81 includes a gantry frame 811, an aluminum profile 812 horizontally mounted on the gantry frame 811, a connecting seat 813 mounted on the aluminum profile 812, a Z-axis adjustment platform 814 vertically mounted on the connecting seat 813, and an upper detection camera 815 vertically mounted on the drive end of the Z-axis adjustment platform 814; the gantry frame 811 is provided with multiple sets of elongated holes 816 placed perpendicular to the aluminum profile 812; the detection end of the upper detection camera 815 is placed downwards;

[0086] During installation: By tightening or loosening the bolts in the elongated hole 816, the position of the aluminum profile 812 in the width direction (X-axis direction) can be adjusted; by tightening or loosening the bolts connecting the aluminum profile 812 and the connecting seat 813, the position of the connecting seat 813 in the length direction (Y-axis direction) of the aluminum profile 812 can be adjusted; and the height can be adjusted by adjusting the Z-axis adjustment platform 814, thereby realizing the adjustment of the upper detection camera 815 in the XYZ three-axis directions.

[0087] Furthermore, such as Figure 10 As shown, in this embodiment, two detection cameras 815 are provided, both of which are used to detect the position of the product IC in the film application station 23, thereby improving the detection accuracy.

[0088] Furthermore, such as Figure 11 As shown, the lower vision component 82 includes a lower vision detection bracket 821, two lower detection cameras 822 vertically and side by side arranged on the lower vision detection bracket 821, and at least one light source 823 arranged on the lower vision detection bracket 821 and located next to the lower detection cameras 822; the detection end of the lower detection camera 822 and the light source 823 are both placed facing upwards.

[0089] During operation: Two lower detection cameras 822 are used to detect the position of the protective film a on the two elongated suction cups 621 respectively; since the lower detection camera 822 detects the position of the protective film a at the bottom of the elongated suction cup 621 from bottom to top, an additional light source 823 is provided to make the lower detection camera 822 take clearer pictures.

[0090] Furthermore, such as Figure 11 As shown, in this embodiment, there are two light sources 823, located on both sides of the two lower detection cameras 822, which makes the brightness more uniform.

[0091] Furthermore, such as Figure 12 As shown, the pressing unit 9 includes a pressing frame 91 mounted on the machine base 1, a Z-axis linear slide 92 vertically mounted on the pressing frame 91, a pressing cylinder 93 vertically mounted on the driving end of the Z-axis linear slide 92, and a pressing head 94 mounted on the driving end of the pressing cylinder 93.

[0092] During operation, the pressing head 94 is driven by the pressing cylinder 93 to flatten the protective film a attached to the IC position of the product; the Z-axis linear slide 92 can adjust the height of the pressing cylinder 93 to adapt to products 10 of different thicknesses.

[0093] Furthermore, such as Figure 12 As shown, the top of the fixture 26 is provided with a contour groove corresponding to the shape of the product 10, and the four sides are provided with drive push blocks 28 to fix the product 10 in the contour groove from four directions. When the upstream production line automatically places the product 10 into the contour groove of the loading station 22, the four side push cylinders 27 extend at the same time, and the four push blocks 28 fix the product 10 in the contour groove from four directions respectively.
