Description

Technical Field

[0001] This utility model relates to the field of liquid crystal screen manufacturing technology, and specifically to a liquid crystal screen IC film application robot. 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 1 are attached side by side to the same lower film 2, and each protective film surface is covered with an independent upper film 3, wherein the upper film 3 is longer than the protective film 1 but shorter than the lower film 2; when applying the film, it is necessary to first peel off the film 2, then apply the protective films 1 separately, and finally peel off the upper film 3.

[0004] For protective films with a "double upper film and same lower film" structure, existing IC film application robots only support independent application of a single film and cannot adapt to the "double upper film and same lower film" structure. The film still needs to be pre-peeled manually, resulting in low automation. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a robotic arm for applying liquid crystal screen IC films.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a liquid crystal screen IC film application robot, comprising a mounting base, a robotic arm mounted on the mounting base, and a material suction component mounted on the drive end of the robotic arm;

[0007] The suction assembly has two elongated suction cups that can be raised and lowered independently, used to pick up two upper films on the same lower film for tearing and applying films respectively;

[0008] Each of the elongated suction cups is divided into two separate areas: an overlapping area where the upper film and the protective film overlap, and a single area where only the portion of the upper film extending beyond the protective film is adsorbed. When the film is peeled off, the overlapping area and the single area can be adsorbed simultaneously; when the upper film is peeled off, only the single area is adsorbed.

[0009] Preferably, the two elongated suction cups are placed symmetrically in a T-shape; each elongated suction cup has a main air channel placed along its length in both the overlapping area and the single area, and multiple vertically placed adsorption holes connected to the main air channel are provided at the bottom; each elongated suction cup has two suction holes connected to the main air channel on its side.

[0010] Preferably, the two main air passages of each of the elongated suction cups are connected to both ends and sealed by a sealing element.

[0011] Preferably, the suction assembly includes a suction cup frame and two staggered cylinders arranged vertically and parallel within the suction cup frame; each of the two elongated suction cups has a mounting portion at its top; the two mounting portions are located between the two staggered cylinders, not only spaced apart, but also connected to the drive ends of the two staggered cylinders respectively.

[0012] Preferably, the suction cup frame includes a connecting plate and upright plates respectively vertically arranged at both ends of the bottom of the connecting plate; the two staggered cylinders are respectively vertically installed on the inner side of the upright plates.

[0013] Preferably, the suction cup holder further includes a reinforcing rod for connecting the lower ends of the two upright plates.

[0014] Preferably, there are two reinforcing rods, located on both sides of the connecting plate.

[0015] Preferably, the length of the mounting part is less than the length of the elongated suction cup; the mounting part is located between the two reinforcing rods, while the elongated suction cup is located below the reinforcing rods.

[0016] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0017] This invention employs two independently liftable elongated suction cups, each divided into overlapping and single areas, specifically adapted to the "double upper film and common lower film" material feeding method, solving the problem of film tearing and reducing manual intervention.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] Appendix Figure 2 The liquid crystal screen IC film application robot of this utility model includes a mounting base 4, a robotic arm 5 disposed on the mounting base 4, and a suction component 6 disposed at the drive end of the robotic arm 5.

[0029] like Figure 5 As shown, the suction assembly 6 has two elongated suction cups 61 that can be raised and lowered independently, which are used to pick up the upper film 3 on the surface of the two protective films 1 on the same lower film 2 for tearing and applying the film respectively.

[0030] like Figure 3 As shown, each of the elongated suction cups 61 is divided into two separate regions: an overlapping region 611 that adsorbs the overlapping portion of the upper film 3 and the protective film 1, and a single region 612 that only adsorbs the portion of the upper film 3 that extends out of the protective film 1; when the film 2 is peeled off, the overlapping region 611 and the single region 612 can be adsorbed simultaneously; when the upper film 3 is peeled off, only the single region 612 is adsorbed.

[0031] At work: such as Figure 7 As shown, a robotic arm for applying LCD screen ICs is installed on an automatic LCD screen IC applying machine. The automatic LCD screen IC applying machine includes a film supply unit 7, a film peeling unit 8, and an applying station 9. The robotic arm 5 drives the suction component 6 to first pick up the protective film 1 from the film supply unit 7 and send it to the film peeling unit 8 to peel off the film 2. Then, it is installed on the product IC at the applying station 9 in two stages, and the upper film 3 is peeled off from the protective film 1 after each application.

[0032] The specific film application process is as follows: the robotic arm 5 drives the suction component 6 to first pick up the protective film 1 from the film supply unit 7. At this time, the two long strip suction cups 61 respectively pick up the upper film 3 on the surface of the two protective films 1 on the same lower film 2.

[0033] Next, the robotic arm 5 drives the suction assembly 6 to deliver the film tearing unit 8 to tear off the film 2. Specifically, the gripper cylinder clamps the extension part of the lower film 2 (taking advantage of the fact that the upper film 3 is shorter than the lower film 2), and works with the film-applying robot to complete the film tearing. At this time, the two long strip suction cups 61 still hold the two pieces of upper film 3 respectively.

[0034] Finally, the protective film 1 is applied to the product IC at the film application station 9 in two stages, and the upper film 3 is peeled off from the protective film 1 after each application.

[0035] Furthermore, such as Figure 4 As shown, the two elongated suction cups 61 are placed symmetrically in a T-shape; each elongated suction cup 61 has a main air channel 613 placed along its length in the overlapping area 611 and the single area 612, and multiple vertically placed suction holes 614 connected to the main air channel 613 are provided at the bottom; each elongated suction cup 61 has two suction holes 615 connected to the main air channel 613 on its side.

[0036] During operation: The two air extraction ports 615 are connected to the vacuum pump via air pipes. When the membrane 2 is torn off, the vacuum pump simultaneously extracts air from the air extraction ports 615 of the overlapping area 611 and the single area 612, creating negative pressure in the main air passages 613 of the overlapping area 611 and the single area 612. This negative pressure is then applied through the adsorption holes 614 to simultaneously adsorb the overlapping portion of the upper membrane 3 and the protective membrane 1, as well as the portion of the upper membrane 3 extending beyond the protective membrane 1, achieving precise tearing of the lower membrane 2 without damaging the protective membrane 1. When the upper membrane 3 is torn off, the vacuum pump only extracts air from the air extraction ports 615 of the single area 612, creating negative pressure in the main air passage 613 of the single area 612. This negative pressure is then applied through the adsorption holes 614 to adsorb the portion of the upper membrane 3 extending beyond the protective membrane 1, preventing the protective membrane 1 from shifting, thus achieving step-by-step membrane tearing.

[0037] Furthermore, such as Figure 5 As shown, each of the elongated suction cups 61 has two main air passages 613 connected to both ends and sealed by a sealing element 616; this structural design facilitates the processing of two main air passages 613 at both ends of the elongated suction cup 61, reducing production costs.

[0038] Furthermore, such as Figure 5 As shown, the suction assembly 6 includes a suction cup frame 62 and two vertically and parallelly arranged staggered cylinders 63 within the suction cup frame 62; each of the two elongated suction cups 61 has a mounting part 617 at its top; the two mounting parts 617 are located between the two staggered cylinders 63, not only placed at intervals, but also connected to the driving ends of the two staggered cylinders 63 respectively.

[0039] During the process of taking material from the film supply unit 7 and peeling off the film 2, both staggered cylinders 63 are in the retracted state; when the film needs to be applied, one of the staggered cylinders 63 extends and drives the elongated suction cup 61 to descend, so that the two elongated suction cups 61 are not on the same plane, which makes it easier to apply the protective film 1 to the product IC.

[0040] Furthermore, such as Figure 5 As shown, the suction cup holder 62 includes a connecting plate 621 and upright plates 622 respectively vertically arranged at both ends of the bottom of the connecting plate 621; the two staggered cylinders 63 are respectively vertically installed on the inner side of the upright plates 622; during installation: first, the mounting parts 617 of the two elongated suction cups 61 are respectively installed on the driving ends of the two staggered cylinders 63, then the two staggered cylinders 63 are respectively vertically installed on the two upright plates 622, and finally the two upright plates 622 are respectively installed on both ends of the bottom of the connecting plate 621, so that the two elongated suction cups 61 are opposite each other, but with a gap.

[0041] Furthermore, such as Figure 5 As shown, the suction cup holder 62 also includes a reinforcing rod 623 for connecting the lower ends of the two upright plates 622; this design makes the overall structure more robust, the lower end is less likely to wobble, and avoids collision between the two long suction cups 61.

[0042] Furthermore, such as Figure 5 As shown, there are two reinforcing rods 623, located on both sides of the connecting plate 621 respectively; this design makes the force on both ends of the upright plate 622 more even, ensuring that the two long strip suction cups 61 are placed in parallel.

[0043] Furthermore, such as Figure 5 As shown, the length of the upright plate 622 is slightly greater than the width of the staggered cylinder 63; the length of the mounting part 617 is not greater than the width of the staggered cylinder 63, but less than the length of the elongated suction cup 61; the mounting part 617 is located between the two reinforcing rods 623, while the elongated suction cup 61 is located below the reinforcing rods 623; this design makes the overall structure more compact.

[0044] Furthermore, the robotic arm 5 can be one of four-axis, five-axis, or six-axis, and can be selected according to requirements.

[0045] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
