Description

Technical Field

[0001] This utility model relates to the field of automatic film application, and in particular to a rotating film application mechanism and device. Background Technology

[0002] A rotary film applicator is an automatic film applicator that uses a fixture to rotate the product relative to a protective film strip in order to wrap and adhere the protective film strip to the surface of the product.

[0003] Existing rotary film applicators, after cutting the protective film strip with a film cutter after applying film to the previous product, require manual application of the end of the protective film strip to the next product. This results in poor continuity of film application, low efficiency, and safety hazards. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a rotating film application mechanism and device, which has high film application efficiency and safety.

[0005] The technical problem to be solved by this utility model is achieved through the following technical solution: A rotating film application mechanism includes a fixture module, a rotation drive module, a cutter module, and a movement drive module. The fixture module and the cutter module are arranged opposite to each other. The rotation drive module drives the fixture module to rotate, and the movement drive module drives the cutter module to move relative to the fixture module. The fixture module includes a rotating disk and two positioning structures. The two positioning structures are symmetrically arranged at 180° on the periphery of the rotating disk. The rotating disk switches the two positioning structures between the first film-applying station and the second film-applying station by rotating. The cutting module includes a film-applying pressure head and a film-cutting blade. The film-cutting blade is disposed on the side of the film-applying pressure head near the fixture module and aligned with the middle of the two positioning structures. The film-applying pressure head has two pressing surfaces on the side near the fixture module. The two pressing surfaces are respectively located on both sides of the film-cutting blade and correspond to the two positioning structures respectively.

[0006] Furthermore, the rotating disk is provided with a cutting groove, which is located between the two positioning structures and aligned with the film cutting blade; when the film cutting blade moves onto the rotating disk, its bottom is located within the cutting groove.

[0007] A rotary film applicator includes a worktable, a feeding mechanism, and at least one film applicator arrangement unit. The film applicator arrangement units are arranged side-by-side on the worktable, and the feeding mechanism is located above each film applicator arrangement unit. Each film applicator arrangement unit includes a rotary film applicator, a product arrangement mechanism, and a film supply mechanism. The rotary film applicator is the aforementioned rotary film applicator. The feeding mechanism includes at least one transfer gripper and a feeding drive module. One transfer gripper corresponds to one film applicator arrangement unit. The feeding drive module drives each transfer gripper to move between the rotary film applicator arrangement unit and the product arrangement mechanism of the corresponding film applicator arrangement unit. When each transfer gripper moves to the corresponding rotary film applicator arrangement unit, it aligns with a positioning structure located at the first film applicator station.

[0008] Furthermore, the worktable surface within the product arrangement mechanism is provided with a transfer area, an arrangement area, and a unloading area. The transfer area and the arrangement area are arranged opposite each other along a first direction, and the arrangement area and the unloading area are arranged opposite each other along a second direction. Each transfer gripper aligns with the transfer area when it moves to the corresponding product arrangement mechanism. The product arrangement mechanism includes a first pushing module and a second pushing module. The first pushing module includes a first pushing plate and a first pushing driver. The first pushing plate is located on the side of the transfer area away from the arrangement area. The first pushing driver is connected to drive the first pushing plate to move between the transfer area and the arrangement area along the first direction. The second pushing module includes a second pushing plate and a second pushing driver. The second pushing plate is located on the side of the arrangement area away from the unloading area. The second pushing driver drives the second pushing plate to move between the arrangement area and the unloading area along the second direction.

[0009] Furthermore, the first direction and the second direction are perpendicular to each other or form an acute angle.

[0010] Furthermore, the second pusher plate is provided with a baffle plate on the side of the arrangement area away from the transfer area. The baffle plate and the first pusher plate are arranged opposite to each other to block the film-coated products pushed by the first pusher plate, so as to prevent the first pusher plate from pushing the film-coated products outside the arrangement area.

[0011] Furthermore, the rotary film application mechanism also includes a roll shaft and multiple guide shafts, which are distributed between the roll shaft and the rotary film application mechanism of the same film application unit according to the required material conveying path.

[0012] Furthermore, the rotary film applicator also includes a feeding mechanism located on the side of the rotary film applicator away from the product arrangement mechanism; the feeding mechanism has at least one feeding channel, and one feeding channel corresponds to one film arrangement unit; the feeding mechanism also includes at least one feeding gripper and a feeding drive module, one feeding gripper corresponds to one film arrangement unit, and the feeding drive module drives each feeding gripper to move between the feeding channel corresponding to the same film arrangement unit and the rotary film applicator; when each feeding gripper moves to the corresponding rotary film applicator, it corresponds to the positioning structure located on the first film applicator station.

[0013] Furthermore, when each feeding gripper moves to the corresponding feeding channel, each transfer gripper moves synchronously to the corresponding rotary film applicator. When each feeding gripper moves to the corresponding rotary film applicator, each transfer gripper moves synchronously to the corresponding product arrangement mechanism.

[0014] Furthermore, the rotating film applicator also includes a feeding mechanism, which is located on the side of the product arrangement mechanism away from the rotating film applicator. The feeding mechanism includes at least one feeding gripper and a feeding drive module. One feeding gripper corresponds to one film arrangement unit. The feeding drive module drives each feeding gripper to move between the product arrangement mechanism of the corresponding film arrangement unit and a preset feeding position. When each feeding gripper moves to the corresponding product arrangement mechanism, it corresponds to the arrangement area.

[0015] The present invention has the following beneficial effects: The rotary film-applying mechanism of the present invention provides a film-applying pressure head with two pressing surfaces in the cutting module, and places the film-cutting blade between the two pressing surfaces of the film-applying pressure head. When the moving drive module drives the cutting module to move closer to the fixture module, after the film-cutting blade cuts the protective film strip from the middle of the two products to be applied, the two pressing surfaces can press and adhere the tail of the separated part and the head of the main part to the surfaces of the two products to be applied, respectively, thereby reducing manual intervention and improving the continuity, efficiency and safety of film application.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," "fixing," and "setting," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Example 1 like Figure 1 As shown, a rotating film applicator includes a fixture module 41, a rotation drive module 42, a cutter module 43, and a movement drive module 44. The fixture module 41 and the cutter module 43 are arranged opposite to each other. The rotation drive module 42 drives the fixture module 41 to rotate, and the movement drive module 44 drives the cutter module 43 to move relative to the fixture module 41. The fixture module 41 includes a rotating disk 411 and two positioning structures 412. The two positioning structures 412 are symmetrically arranged at 180° on the periphery of the rotating disk 411. The rotating disk 411 switches the two positioning structures 412 between the first film application station and the second film application station by rotating. The cutting module 43 includes a film-applying pressure head 431 and a film-cutting blade 432. The film-cutting blade 432 is disposed on the side of the film-applying pressure head 431 near the fixture module 41 and aligned with the middle of the two positioning structures 412. The film-applying pressure head 431 has two pressing surfaces 433 on the side near the fixture module 41. The two pressing surfaces 433 are respectively located on both sides of the film-cutting blade 432 and respectively correspond to the two positioning structures 412.

[0028] When applying the screen protector, such as Figure 2As shown, two products b1 to be coated with film are placed on the two positioning structures 412 respectively. Then, the head of the protective film strip c is manually attached to the surface of the product b1 to be coated with film near the cutter module 43 located at the second coating station. After the equipment is started, the rotary drive module 42 first drives the fixture module 41 to rotate 180°. At this time, the product b1 to be coated with film originally located at the second coating station is switched to the first coating station. The protective film strip c is wrapped around the surface of the product b1 to be coated with film 180° and attached to the other surface of the product b1 to be coated with film. The product b1 to be coated with film originally located at the first coating station is switched to the second coating station. The protective film strip c is attached to the surface of the product b1 to be coated with film near the cutter module 43. The moving drive module 44 then drives the cutter module 43 to move closer to the fixture module. In block 41, during the movement, the cutting blade 432 first contacts the protective film strip c and cuts the protective film strip c from the middle of the two products b1 to be coated, so that the protective film strip c forms a separate part c1 and a main part c2. The two pressing surfaces 433 of the coating head 431 then contact the tail of the separate part c1 and the head of the main part c2 respectively, so as to press the tail of the separate part c1 and the head of the main part c2 tightly onto the surfaces of the two products b1 to be coated. Thus, except for the first product which requires manual pre-coating, the coating of other products does not require manual intervention.

[0029] The rotary film-applying mechanism of this utility model has a film-applying pressure head 431 with two pressing surfaces 433 in the cutting module 43, and the film-cutting blade 432 is placed between the two pressing surfaces 433 of the film-applying pressure head 431. When the moving drive module 44 drives the cutting module 43 to move closer to the fixture module 41, after the film-cutting blade 432 cuts the protective film strip c from the middle of the two products b1 to be applied, the two pressing surfaces 433 can press and adhere the tail of the separated part c1 and the head of the main part c2 to the surface of the two products b1 to be applied, respectively. This reduces manual intervention and improves the continuity, efficiency and safety of film application.

[0030] In this embodiment, the rotary drive module 42 is a motor module and the motion drive module 44 is a cylinder module. Of course, the rotary drive module 42 and the motion drive module 44 can also be other conventional drive source modules, and should not be limited thereto.

[0031] Preferably, the shape of the positioning structure 412 is adapted to the inner surface shape of the product b1 to be coated, and the shape of the pressing surface 433 is adapted to the outer surface shape of the product b1 to be coated.

[0032] The rotating disk 411 is provided with a cutting groove 413, which is located between the two positioning structures 412 and aligned with the film cutting blade 432. When the film cutting blade 432 moves onto the rotating disk 411, its bottom is located in the cutting groove 413 to increase the length of the film cutting blade 432, avoid missing the bottom edge of the protective film strip c, and prevent the bottom of the film cutting blade 432 from contacting and rubbing against the surface of the rotating disk 411.

[0033] Example 2 like Figure 3 and 4 As shown, a rotary film applicator includes a worktable 20, a feeding mechanism 30, and at least one film applicator arrangement unit A. Each film applicator arrangement unit A is arranged side-by-side on the worktable 20, and the feeding mechanism 30 is located above each film applicator arrangement unit A. Each film applicator arrangement unit A includes a rotary film applicator 40, a product arrangement mechanism 50, and a film supply mechanism 60. The rotary film applicator 40 is the rotary film applicator 40 described in Embodiment 1. The feeding mechanism 30 includes at least one transfer gripper 31 and a feeding drive module 33. One transfer gripper 31 corresponds to one film applicator arrangement unit A. The feeding drive module 33 drives each transfer gripper 31 to move between the rotary film applicator 40 and the product arrangement mechanism 50 of the corresponding film applicator arrangement unit A. When each transfer gripper 31 moves to the corresponding rotary film applicator 40, it corresponds to the positioning structure 412 located at the first film applicator station.

[0034] During operation, the film supply mechanism 60 provides the protective film strip c to the rotating film application mechanism 40 of the same film application unit A. The feeding mechanism 30 transfers the film-applied products b2 from each rotating film application mechanism 40 to the product arrangement mechanism 50 of the same film application unit A. The product arrangement mechanism 50 arranges the film-applied products b2 delivered by the feeding mechanism 30 neatly to facilitate batch unloading.

[0035] In this embodiment, the transfer gripper 31 can be a negative pressure suction cup with lifting function, a robotic gripper or other conventional gripper.

[0036] The feeding drive module 33 is a two-axis movement module or a three-axis movement module.

[0037] like Figure 5 and 6As shown, the worktable 20 is provided with a transfer area 21, an arrangement area 22 and a feeding area 23 in the product arrangement mechanism 50. The transfer area 21 and the arrangement area 22 are arranged opposite to each other along a first direction, and the arrangement area 22 and the feeding area 23 are arranged opposite to each other along a second direction. Each transfer gripper 31 corresponds to the transfer area 21 when it moves to the corresponding product arrangement mechanism 50.

[0038] The product arrangement mechanism 50 includes a first pushing module 51 and a second pushing module 52. The first pusher module 51 includes a first pusher plate 511 and a first pusher driver 512. The first pusher plate 511 is located on the side of the transfer area 21 away from the arrangement area 22. The first pusher driver 512 drives the first pusher plate 511 to move between the transfer area 21 and the arrangement area 22 along the first direction. The second pushing module 52 includes a second pushing plate 521 and a second pushing driver 522. The second pushing plate 521 is located on the side of the arrangement area 22 away from the unloading area 23. The second pushing driver 522 drives the second pushing plate 521 to move between the arrangement area 22 and the unloading area 23 along the second direction.

[0039] During operation, the first pushing module 51 is used to push the film-coated product b2 in the transfer area 21 into the arrangement area 22 for neat arrangement, and the second pushing module 52 is used to push the film-coated product b2 neatly arranged in the arrangement area 22 into the unloading area 23 to wait for unloading.

[0040] The transfer gripper 31 of the feeding mechanism 30 first removes the film-coated product b2 from the rotating film-coating mechanism 40 into the transfer area 21. Then, the first pusher driver 512 drives the first pusher plate 511 to move along the first direction towards the arrangement area 22, so as to push the film-coated product b2 located in the transfer area 21 into the arrangement area 22. Next, the first pusher driver 512 drives the first pusher plate 511 to move along the first direction away from the arrangement area 22, so that the first pusher plate 511 returns to the transfer area 21 away from the arrangement area 22. On one side; repeat the above process, when the number of film-coated products b2 in the arrangement area 22 reaches a preset number, the second pusher driver 522 drives the second pusher plate 521 to move along the second direction and approach the unloading area 23, so as to push the neatly arranged film-coated products b2 into the unloading area 23 to wait for unloading, and then the second pusher driver 522 drives the second pusher plate 521 to move along the second direction away from the unloading area 23, so that the second pusher plate 521 is reset to the side of the arrangement area 22 away from the unloading area 23.

[0041] The first direction and the second direction are perpendicular to each other or form an acute angle.

[0042] In this embodiment, both the first pusher driver 512 and the second pusher driver 522 are drive cylinders. Of course, the first pusher driver 512 and the second pusher driver 522 can also use other conventional drive sources, and should not be limited thereto.

[0043] Preferably, the second pusher plate 521 is provided with a baffle plate 523 on the side of the arrangement area 22 away from the transfer area 21. The baffle plate 523 and the first pusher plate 511 are arranged opposite to each other to block the film-coated product b2 pushed by the first pusher plate 511, so as to prevent the first pusher plate 511 from pushing the film-coated product b2 outside the arrangement area 22.

[0044] The rotary film applicator 40 also includes a roll 61 and multiple guide shafts 62, which are distributed between the roll 61 and the rotary film applicator 40 in the same film applicator unit A according to the required material conveying path.

[0045] like Figure 3 , 4As shown in Figure 7, the rotary film applicator further includes a feeding mechanism 10, which is located on the side of the rotary film applicator 40 away from the product arrangement mechanism 50. The feeding mechanism 10 is provided with at least one feeding channel 11, and one feeding channel 11 corresponds to one film arrangement unit A. The feeding mechanism 30 further includes at least one feeding gripper 32, and one feeding gripper 32 corresponds to one film arrangement unit A. The feeding drive module 33 drives each feeding gripper 32 to move between the feeding channel 11 corresponding to the same film arrangement unit A and the rotary film applicator 40. When each feeding gripper 32 moves to the corresponding rotary film applicator 40, it corresponds to the positioning structure 412 located on the first film applicator station.

[0046] Preferably, the movement between each feeding gripper 32 and each transfer gripper 31 is synchronized. That is, when each feeding gripper 32 moves to the corresponding feeding channel 11, each transfer gripper 31 moves synchronously to the corresponding rotating film applicator 40. When each feeding gripper 32 moves to the corresponding rotating film applicator 40, each transfer gripper 31 moves synchronously to the corresponding product arrangement mechanism 50.

[0047] In this embodiment, the feeding gripper 32 can be a negative pressure suction cup, a robotic gripper, or other conventional grippers. The feeding mechanism 10 can be a conveyor belt mechanism, and the conveyor belt mechanism is provided with limiting structures 12 for forming each feeding channel 11.

[0048] like Figure 3 As shown, the rotating film applicator further includes a feeding mechanism 70, which is located on the side of the product arrangement mechanism 50 away from the rotating film applicator 40. The feeding mechanism 70 includes at least one feeding gripper 71 and a feeding drive module 72. One feeding gripper 71 corresponds to one film arrangement unit A. The feeding drive module 72 drives each feeding gripper 71 to move between the product arrangement mechanism 50 corresponding to the film arrangement unit A and a preset feeding position. When each feeding gripper 71 moves to the corresponding product arrangement mechanism 50, it corresponds to the arrangement area 22.

[0049] In this embodiment, the feeding gripper 71 can be composed of multiple negative pressure suction cups with lifting function, multiple robotic grippers or multiple other conventional grippers, with one negative pressure suction cup, robotic gripper or conventional gripper corresponding to one film-coated product b2.

[0050] The feeding drive module 72 is a two-axis movement module or a three-axis movement module.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present utility model, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the present utility model.
