Description

Technical Field

[0001] This application relates to the field of bonding equipment technology, and in particular to a bonding module and bonding method. Background Technology

[0002] During the production of some membrane materials, protective films need to be attached to both sides. In related technologies, protective films of the same size are directly attached to both sides of the material strip to form a composite film. If the size of the protective film is the same as that of the material strip, the protective film cannot cover the sides of the material strip, and the protective film in the composite film is easy to peel off from the sides of the composite film. If the size of the protective film is larger than that of the material strip, although the two protective films can be directly attached to their ends to cover the material strip, it will increase the overall width of the composite film and affect its use. Summary of the Invention

[0024] Reference Figures 1 to 2 The film application module according to the first aspect of this application includes: A first guide roller 100, with a soft layer 110 formed on its periphery; The second guide roller 200 is shorter than the width of the first guide roller 100, causing both ends of the first guide roller 100 to protrude from the second guide roller 200. The second guide roller 200 and the first guide roller 100 are used for the passage of the first protective film 710, the material belt 720, and the second protective film 730. The widths of the first protective film 710, the material belt 720, and the second protective film 730 decrease sequentially. The width of the first protective film 710 is shorter than the width of the first guide roller 100 and longer than the width of the second guide roller 200. The widths of the material belt 720 and the second protective film 730 are shorter than the width of the second guide roller 200. The first guide roller 100 and the second guide roller 200 press together the first protective film 710, the material strip 720 and the second protective film 730 to form a composite film; and the second guide roller 200 and the soft layer 110 of the first guide roller 100 are pressed together to make the two ends of the first protective film 710 bend. A bending mechanism 300 is disposed behind the first guide roller 100 and the second guide roller 200. The bending mechanism 300 is used to pass through the composite film and to bend both ends of the first protective film 710 to below the second protective film 730. Rolling mechanism 400 is located behind bending mechanism 300 and is used to roll the composite film that has passed through bending mechanism 300 so that the two ends of the first protective film 710 are attached to the lower end of the second protective film 730, and the first protective film 710 and the second protective film 730 wrap the material strip 720.

[0025] It is understood that the first protective film 710, the material strip 720, and the second protective film 730 enter between the first guide roller 100 and the second guide roller 200, and the first protective film 710, the material strip 720, and the second protective film 730 are stacked sequentially along the height direction to form a composite film. The second guide roller 200 is pressed into the soft layer 110 of the first guide roller 100, so that the composite film is pressed into the soft layer 110. Since the width of the material strip 720 and the second protective film 730 is shorter than the width of the second guide roller 200, and the width of the first protective film 710 is shorter than the width of the first guide roller 100 and longer than the width of the second guide roller 200, the middle part of the first protective film 710, the material strip 720, and the second protective film 730 are pressed into the soft layer 110 by the second guide roller 200. The two ends of the first protective film 710 do not contact the second guide roller 200, but the pressing between the second guide roller 200 and the soft layer 110 of the first guide roller 100 will form a depression on the soft layer 110. Since the middle part of the first protective film 710 is pressed into the depression, the two ends of the first protective film 710 are also brought into the depression and bend relative to the middle part of the first protective film 710.

[0026] Then, the composite film will pass through the bending mechanism 300, which will further bend the first protective film 710. Specifically, the bending mechanism 300 will bend the bent portions at both ends of the first protective film 710 and bend the two ends of the first protective film 710 to below the second protective film 730.

[0027] Next, the composite film is rolled by the rolling mechanism 400. Since the two ends of the first protective film 710 have been bent to the bottom of the second protective film 730, after the composite film is rolled, the two ends of the first protective film 710 will be attached to the bottom of the second protective film 730. The first protective film 710 and the second protective film 730 will wrap the material strip 720.

[0028] In summary, the composite film formed by the film application module of this application can wrap the material strip 720 with the first protective film 710 and the second protective film 730. The two ends of the first protective film 710 are bent to fit with the lower end of the second protective film 730, so that the first protective film 710 is not easy to peel off and does not affect the width of the composite film.

[0029] Reference Figure 3 and Figure 4 According to some embodiments of this application, the bending mechanism 300 includes two first guide wheels 310, and a first guide groove 311 is formed on the periphery of the first guide wheels 310. The first guide wheels 310 are used to pass through the composite film. The distance between the walls of the first guide grooves 311 of the two first guide wheels 310 is less than the width of the first protective film 710 and greater than the width of the material strip 720, so that the first protective film 710 passing between the first guide wheels 310 can be bent along the wall of the first guide groove 311.

[0030] Understandably, the composite film passes between the two first guide wheels 310. Since the distance between the walls of the two first guide grooves 311 is less than the width of the first protective film 710 and greater than the width of the material strip 720, the material strip 720 and the second protective film 730 are not affected by the first guide grooves 311. The two ends of the first protective film 710 will contact the wall of the first guide groove 311. The two ends of the first protective film 710 are bent along the first guide groove 311, so that the two ends of the first protective film 710 are bent to the bottom of the second protective film 730.

[0031] Reference Figure 3 and Figure 4 According to some embodiments of this application, the wall of the first guide groove 311 has a first wall surface 311a and a second wall surface 311b. The first wall surface 311a and the second wall surface 311b are intersecting. The first wall surface 311a is horizontally arranged, and the second wall surface 311b is inclined from top to bottom toward the direction of approaching another first guide wheel 310. The first protective film 710 between the first guide wheels 310 can be bent along the second wall surface 311b.

[0032] It is understood that the first guide groove 311 has a horizontally arranged first wall surface 311a and an inclined second wall surface 311b. The horizontally arranged first wall surface 311a ensures that the middle part of the first protective film 710, the material belt 720, and the second protective film 730 are flush, and ensures that the two ends of the first protective film 710 do not flip up. It also allows the two ends of the first protective film 710 to bend downward and inward along the second wall surface 311b that is connected to the first wall surface 311a, so that the two ends of the first protective film 710 bend towards each other, so that the two ends of the first protective film 710 bend below the second protective film 730.

[0033] In other embodiments, the wall surface of the first guide groove 311 can be set as an arc surface, so that the two ends of the first protective film 710 are bent along the arc surface.

[0034] Reference Figure 3 According to some embodiments of this application, the bending mechanism 300 further includes a first mounting frame 320, a first slide rail 330, and two first slide blocks 340. The first slide rail 330 is disposed on the first mounting frame 320 along the width direction of the first mounting frame 320. Each first guide wheel 310 is rotatably disposed on a first slide block 340, and the first slide block 340 is slidably disposed on the first slide rail 330.

[0035] Understandably, the first slide rail 330 extends along the width direction of the first mounting bracket 320 and is disposed on the first mounting bracket 320 along the width direction. The first slide block 340 can slide along the first slide rail 330 so that the first slide block 340 can slide along the width direction of the first mounting bracket 320, thereby driving the first guide wheel 310 to slide, so as to adjust the distance between the two first guide wheels 310, thereby adapting to the first protective film 710 of different widths, or to adjust the degree of bending at both ends of the first protective film 710, for example, making the first guide wheels 310 closer together, so that the two ends of the first protective film 710 bend more and the degree of bending is greater.

[0036] It should be understood that the width direction of the first mounting bracket 320 is the width direction of the composite film.

[0037] Reference Figure 1 According to some embodiments of this application, a position adjustment mechanism 600 is also included, which drives the first guide roller 100 and / or the second guide roller 200 to adjust the distance between the first guide roller 100 and the second guide roller 200.

[0038] Understandably, the position adjustment mechanism 600 can bring the first guide roller 100 and the second guide roller 200 closer together or further apart, thereby adjusting the degree of compression of the soft layer 110 of the first guide roller 100 by the second guide roller 200. This causes the indentation created by the second guide roller 200 within the soft layer 110 to increase or decrease, thereby adjusting the curvature of both ends of the first protective film 710. Alternatively, the first guide roller 100 and the second guide roller 200 can be completely separated to facilitate the placement of the material belt 720, the first protective film 710, and the second protective film 730 between the first guide roller 100 and the second guide roller 200.

[0039] Specifically, the position adjustment mechanism 600 is driven to connect to the second guide roller 200, which is used to raise and lower the second guide roller 200. In other embodiments, the position adjustment mechanism 600 may also be driven to connect to the first guide roller 100, or simultaneously drive the first guide roller 100 and the second guide roller 200.

[0040] According to some embodiments of this application, a heating mechanism (not shown in the figures) is also included for heating the composite film.

[0041] Understandably, the heating mechanism allows the first protective film 710 and the second protective film 730 to adhere better to the material strip 720.

[0042] According to some embodiments of this application, the heating mechanism includes a heating tube disposed within the first guide roller 100 and / or the second guide roller 200, for heating the first guide roller 100 and / or the second guide roller 200.

[0043] It is understood that the composite film is heated when the first guide roller 100 and / or the second guide roller 200 presses the material by means of heating tubes provided in the first guide roller 100 and / or the second guide roller 200.

[0044] Reference Figure 1 and Figure 5 According to some embodiments of this application, a guiding mechanism 500 is also included, which is disposed in front of the first guide roller 100 and the second guide roller 200 for guiding the material belt 720.

[0045] Understandably, the guiding mechanism 500 can guide and correct the material belt 720, so that the material belt 720 can enter between the first guide roller 100 and the second guide roller 200 in the correct direction.

[0046] Reference Figure 5 According to some embodiments of this application, the guiding mechanism 500 includes a second mounting frame 520, a second slide rail 530, two second slide blocks 540, and two second guide wheels 510. A second guide groove 511 is formed on the periphery of the second guide wheel 510. The two second guide wheels 510 are used to pass through the material belt 720. The groove wall of the second guide groove 511 limits the two ends of the material belt 720. The second slide rail 530 is disposed on the second mounting frame 520 along the width direction of the second mounting frame 520. Each second guide wheel 510 is rotatably disposed on a second slide block 540. The second slide block 540 is slidably disposed on the second slide rail 530.

[0047] Understandably, the material strip 720 passes between the two second guide wheels 510. The groove wall of the second guide groove 511 limits both sides of the material strip 720 and guides the material strip 720 so that it exits the second guide groove 511 in the correct direction. The second slide rail 530 extends along the width direction of the second mounting frame 520 and is disposed on the second mounting frame 520 along the width direction. The second slide block 540 can slide along the second slide rail 530 so that the second slide block 540 can slide along the width direction of the second mounting frame 520, thereby driving the second guide wheel 510 to slide, thereby adjusting the distance between the two second guide wheels 510 and thus adapting to material strips 720 of different widths.

[0048] It should be understood that the width direction of the second mounting bracket 520 is the same as the width direction of the strip 720.

[0049] The film application method according to the second aspect of this application includes the following steps: A composite film is formed by sequentially laminating a first protective film 710, a material strip 720, and a second protective film 730; wherein the width of the first protective film 710, the width of the material strip 720, and the width of the second protective film 730 decrease sequentially. The two ends of the first protective film 710 are bent; The first protective film 710 on the composite film is bent so that both ends of the first protective film 710 are bent below the second protective film 730; Roll-pressed composite film, such that both ends of the first protective film 710 are attached to the lower end of the second protective film 730, and the first protective film 710 and the second protective film 730 wrap the material strip 720.

[0050] The bonding method according to the second aspect of this application has at least the following beneficial effects: including all the beneficial effects of the bonding module of the first aspect of the embodiment described above, which will not be repeated here.

[0051] Understandably, the first protective film 710, the material strip 720, and the second protective film 730 are combined to form a composite film. Then, the two ends of the longer first protective film 710 are initially bent, and then the two ends of the first protective film 710 are bent to the bottom of the second protective film 730. Next, the composite film is rolled to make the two ends of the first protective film 710 adhere to the bottom of the second protective film 730. The first protective film 710 and the second protective film 730 wrap the material strip 720.

[0052] Since the portions of the first protective film 710 that are longer than the material strip 720 at both ends will be bent, folded and attached to the lower end of the second protective film 730, the width of the composite film will not be affected. Furthermore, since the portions of the first protective film 710 are bent and attached to the lower end of the second protective film 730, the first protective film 710 and the second protective film 730 wrap around the material strip 720, making the first protective film 710 and the second protective film 730 difficult to peel off.

[0053] Specifically, the film application method of the second aspect of this application is implemented by the film application module of the first aspect of the application described above.

[0054] Specifically, a composite film is formed by combining the first protective film 710, the material strip 720, and the second protective film 730 in one pass using the first guide roller 100 and the second guide roller 200. The second guide roller 200 presses the soft layer 110 of the first guide roller 100, causing the two ends of the first protective film 710 to bend relative to its center. Then, the bending mechanism 300 further bends the two ends of the first protective film 710, causing them to bend below the second protective film 730. Through roll pressing, the two ends of the first protective film 710 adhere to the lower end of the second protective film 730, and the first and second protective films 710 and 730 wrap around the material strip 720.

[0055] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
