Description

Technical Field

[0001] This invention relates to the field of film application equipment technology, and more particularly to an inverted film application device. Background Technology

[0002] In the production process of electronic products such as mobile phones, watches, and tablets, protective films need to be pasted on the surface of the electronic products to avoid surface damage. In order to mark and assemble the products, auxiliary materials (foam, blue film, double-sided tape, etc.) need to be applied to them. Hereinafter, the above-mentioned protective films and auxiliary materials are collectively referred to as coatings.

[0003] In related technologies, there are generally two methods for lamination: First, a positioning fixture is used to position the product / film, followed by manual application. This method is inefficient, labor-intensive, and produces inconsistent quality. Second, an automated lamination device is used. Specifically, existing lamination devices typically include a product conveying mechanism and a lamination mechanism. The general lamination process is as follows: the product is carried on the product conveying mechanism, which transports the product to the underside of the lamination mechanism. The lamination mechanism then picks up the film and presses it onto the upper surface of the product. However, when lamination is needed on the lower surface of the product (i.e., the surface supported by the conveying mechanism), a robotic arm or other flipping mechanism is required to first flip the product so that the lower surface to be laminated faces upwards. Then, the lamination mechanism applies the film, and often the product needs to be flipped back after lamination. This method is complex, has a slow production cycle, and is inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide an inverted film application device that can apply film to the lower surface of a product without flipping it over. The device is simple to operate, has a fast production cycle, and high production efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution: The inverted film application device includes: The feeder module is capable of conveying a material belt and peeling the end of the coating on the material belt from the material belt; The inverted module can grip the product and position the surface of the product to be coated with the film facing downwards. The lateral movement module can drive the inverted module to move along the first horizontal direction to above the feeder feeding module; The pressing module, installed on the feeder module, is capable of outputting vertical movement to press the peeled end of the film against the surface of the film to be applied from bottom to top; The transverse module can drive the product with the film pressed against it to move along the first horizontal direction, while the feeder module drives the conveyor belt to attach the film to the surface of the film to be applied.

[0006] As an optional solution, the pressing module includes a lifting drive assembly, a first mounting component, a pressing component, and an elastic element. The lifting drive assembly is mounted on the feeder module. The first mounting component is connected to the output end of the lifting drive assembly. The pressing component is slidably engaged with the first mounting component in the vertical direction. The elastic element is connected between the first mounting component and the pressing component. The lifting drive assembly can drive the pressing component to move up and down, so that the pressing component can press the end of the material strip against the surface of the film to be applied. The elastic element is configured to buffer the pressing action of the pressing component.

[0007] As an alternative, the pressing assembly includes a bracket and a pressing roller, the bracket being slidably engaged with the first mounting member along the vertical direction, and the pressing roller being rotatably mounted on the bracket.

[0008] As an optional solution, the inverted film application device further includes a pressure detection component, which is fixedly connected to the inverted module. The test surface of the pressure detection component is set downwards. The lateral movement module can drive the pressure detection component to move above the pressure-receiving module. The pressure-receiving module can output an upward movement and press against the test surface of the pressure detection component.

[0009] As an optional solution, the inverted module includes a mounting plate and a gripping mechanism. The mounting plate is connected to the output end of the transverse module, and the gripping mechanism is mounted on the mounting plate and used to grip the product. The position of the gripping mechanism relative to the mounting plate in the vertical direction is adjustable.

[0010] As an optional solution, the upside-down module further includes a locking component, and: The mounting structure is disposed on the mounting plate, and one end of the locking component is connected to the gripping mechanism, while the other end can be selectively connected to different positions of the mounting structure. A marking structure is disposed on the mounting plate, and the marking structure is used to mark the position of the locking component.

[0011] As an optional solution, the grasping mechanism includes: A support assembly that slides with the mounting plate along the vertical direction; A plurality of suction cups are disposed on the underside of the support assembly. The suction cups are connected to an external negative pressure mechanism and are configured to adsorb and fix the upper surface of the product.

[0012] As an optional solution, the support assembly includes a connecting plate and an adjusting plate assembly. The connecting plate is slidably engaged with the mounting plate along the vertical direction, and the adjusting plate assembly is slidably engaged with the connecting plate along a second horizontal direction. The suction cup is mounted on the adjusting plate assembly, and the second horizontal direction is perpendicular to the first horizontal direction. The gripping mechanism further includes a micrometer adjustment assembly, which connects the connecting plate and the adjustment plate group. The micrometer adjustment assembly is configured to adjust the position of the adjustment plate group relative to the connecting plate along the second horizontal direction.

[0013] As an optional solution, the lower side of the support component is provided with: A vertical positioning boss is configured to abut against the upper surface of the product, and the suction cup is embedded within the vertical positioning boss; and / or A first positioning part is configured to position the product along the first horizontal direction; and / or The second positioning part is configured to position the product along a second horizontal direction, which is perpendicular to the first horizontal direction.

[0014] As an alternative, the stroke output of the pressure module is adjustable, so that the pressure exerted by the pressure module on the coating is adjustable.

[0015] The beneficial effects of this invention are: The inverted film-applying device of the present invention includes a feeder module, an inverted film-applying module, a traverse module, and a pressing module. When applying film to the lower surface (i.e., the surface to be filmed) of a product conveyed by an upstream conveyor, the traverse module first drives the inverted film-applying module to move above the product conveyed by the upstream conveyor. Then, the inverted film-applying module directly grasps the product, keeping the surface to be filmed facing downwards. Next, the traverse module drives the inverted film-applying module and the product it grasps together to move above the pressing module. During this process, the feeder module conveys a material belt and peels off the end of the film on the material belt through its own blade assembly. Then, the pressing module outputs a vertical upward movement, thereby pressing the peeled portion of the film against the lower side of the surface to be filmed on the product. Then, the traverse module drives the product with the film pressed against to move along a first horizontal direction, while the feeder module drives the conveyor belt to completely peel the film off the material belt and completely apply it to the surface to be filmed on the product under the limiting position of the pressing module. In other words, the inverted film-applying device of the present invention keeps the product's posture unchanged (i.e., the lower surface is facing down) when applying film to the lower surface of the product. With the coordinated action of the feeder module, the traverse module, and the pressing module, automatic film application is completed. Compared with manual film application, the film application quality is more stable. The product does not need to be flipped before or after film application. The entire film application process is simple, has a fast production cycle, and high production efficiency. The film-applying device does not require a flipping module, resulting in low cost.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention and not the entire structure.

[0019] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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; 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 invention based on the specific circumstances.

[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0021] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0022] This embodiment provides an upside-down film application device that can apply film to the lower surface (i.e., the surface to be filmed) of a product without flipping it over. Typically, the film 62 is stored in the form of a film roll. Figure 1 This is a schematic diagram of the unfolded laminated roll, as shown below. Figure 1 As shown, the laminating roll includes a strip 61 and a laminating film 62. The strip 61 can be a strip-shaped release film, and the laminating film 62 is arranged at intervals along the length of the strip 61. The following describes the specific structural details of the inverted laminating device, taking the example of adhering the laminating film 62 to the lower surface of the product.

[0023] like Figure 2As shown, the inverted film application device includes a feeder module 10, an inverted application module 20, a lateral movement module 30, and a pressing module 40. The feeder module 10 conveys a material belt 61 and peels the end of the film 62 from the belt 61. The inverted application module 20 grips the product and positions it with the surface to be filmed facing downwards. The lateral movement module 30 drives the inverted application module 20 to move along a first horizontal direction above the feeder module 10. The pressing module 40, mounted on the feeder module 10, outputs vertical movement to press the peeled end of the film 62 against the surface to be filmed from bottom to top. The lateral movement module 30 drives the product with the film 62 pressed against it to move along the first horizontal direction, while the feeder module 10 simultaneously drives the conveyor belt 61 to adhere the film 62 to the surface to be filmed.

[0024] When applying film to the lower surface (i.e., the surface to be filmed) of a product conveyed by an upstream conveyor using the inverted film applicator of this embodiment, the lateral movement module 30 first drives the inverted film applicator 20 to move above the product conveyed by the upstream conveyor. Then, the inverted film applicator 20 grips the product, keeping the surface to be filmed facing downwards. Next, the lateral movement module 30 drives the inverted film applicator 20 and the product it grips together to move above the pressing module 40. During this process, the feeder module 10 conveys material. The conveyor belt 61 peels off the end of the film 62 on the conveyor belt 61 through its own blade assembly 12 structure; then, the pressing module 40 outputs a vertical upward movement, thereby pressing the peeled part of the film 62 against the lower surface of the product; then, the traverse module 30 drives the product with the film 62 pressed against it to move in the first horizontal direction, while the feeder module 10 drives the conveyor belt 61 to completely peel the film 62 off the conveyor belt 61 and completely adhere it to the surface of the product to be covered under the limit of the pressing module 40. In other words, the inverted film-applying device in this embodiment keeps the product's posture unchanged (i.e., the lower surface is still facing down) when applying film to the lower surface of the product. With the coordinated action of the feeder module 10, the transverse module 30, and the pressing module 40, automatic film application is completed. Compared with manual film application, the film application quality is more stable. The product does not need to be flipped before or after film application. The entire film application process is simple, has a fast production cycle, and high production efficiency. The film application device also does not need to be equipped with a flipping module, resulting in a simple structure and low manufacturing cost.

[0025] In this embodiment, the transverse module 30 can be an existing linear module formed by a motor and a lead screw and nut, or a linear motor module, etc., without specific limitations. Specifically, the way the inverted module 20 contacts the product on the upstream conveyor can be by configuring a lifting module, which drives the transverse module 30 and the inverted module 20 to move up and down synchronously. Alternatively, the upstream conveyor itself can lift the product, allowing it to contact and be grasped by the inverted module 20, without further limitations.

[0026] like Figure 2 As shown, the feeder module 10 includes a support plate 11, an unwinding roller 13, a take-up roller 14, and a cutter assembly 12. The unwinding roller 13, the take-up roller 14, and the cutter assembly 12 are all mounted on the support plate 11. The coated roll is mounted on the unwinding roller 13, and the waste roll is mounted on the take-up roller 14. The material strip 61 extends from the unwinding roller 13 and passes through the cutter assembly 12, finally winding around the waste roll. The unwinding roller 13 and the take-up roller 14 cooperate to realize the conveying of the material strip 61. Figure 2 The dashed arrows in the diagram represent the movement path of the material strip 61 on the feeder module 10. Because the cutter assembly 12 creates a sharp corner on the conveying path of the material strip 61, the end of the film 62 will peel off from the material strip 61 when it passes this corner. It should be noted that after the pressing assembly 43 presses the film 62 against the lower surface of the product, the cutter assembly 12 will retract under the corresponding drive structure, thereby avoiding subsequent film application. It is understood that the feeder module 10 is a mature existing module. Without departing from the inventive concept of this application, the specific driving methods of the unwinding roller 13 and the take-up roller 14, the direction control and tension adjustment of the material strip 61, and the specific structure and drive of the cutter assembly 12 can be any of the existing technologies.

[0027] like Figure 2 and Figure 3 As shown, the pressing module 40 includes a lifting drive assembly 41, a first mounting member 42, a pressing component 43, and an elastic element (not shown). The lifting drive assembly 41 is mounted on the feeder module 10. The first mounting member 42 is connected to the output end of the lifting drive assembly 41. The pressing component 43 is slidably engaged with the first mounting member 42 in the vertical direction. The elastic element is connected between the first mounting member 42 and the pressing component 43. The lifting drive assembly 41 can drive the pressing component 43 to move up and down, so that the pressing component 43 can press the end of the material strip 61 against the surface of the product to be coated. The elastic element is configured to buffer the pressing action of the pressing component 43. By setting the sliding engagement between the pressing component 43 and the first mounting member 42, and setting the elastic element between them, rigid collisions between the pressing component 43 and the product can be avoided, thereby preventing damage to the product during the coating process. In this embodiment, the elastic element can be a spring. The lifting drive assembly 41 can be a slide cylinder.

[0028] like Figure 3As shown, the pressing module 40 also includes a second mounting member 45, and the lifting drive assembly 41 is fixed to the support plate 11 of the feeder feeding module 10 through the second mounting member 45. The pressing module 40 also includes a first guide assembly 46, and the pressing assembly 43 is slidably engaged with the first mounting member 42 through the first guide assembly 46. The first guide assembly 46 can limit the movement direction of the pressing assembly 43 relative to the first mounting member 42, preventing the pressing assembly 43 from being misaligned under the action of the elastic member, and ensuring that the pressing assembly 43 can accurately press the end of the film 62 against the appropriate position of the product. Optionally, the first guide assembly 46 includes a first guide rail and a first slider. The first guide rail extends vertically and is fixed to the first mounting member 42. The first slider is fixedly connected to the pressing assembly 43 and slidably engaged with the first guide rail. Of course, in other embodiments, the mounting positions of the first guide rail and the first slider can also be interchanged.

[0029] like Figure 3 As shown, the pressing assembly 43 includes a bracket 431 and a pressing roller 432. The bracket 431 is slidably engaged with the first mounting member 42 in the vertical direction, and the pressing roller 432 is rotatably mounted on the bracket 431. During the movement of the inverted bonding module 20 carrying the product along the first horizontal direction, the entire pressing module 40 is fixed in position along the first horizontal direction. By setting the pressing roller 432 to rotate relative to the bracket 431, the friction between the pressing assembly 43 and the film 62 can be reduced, ensuring smooth movement of the product and the film 62, and also preventing frictional damage to the film 62 and the pressing assembly 43. In this embodiment, the axial direction of the pressing roller 432 extends along the second horizontal direction.

[0030] like Figure 2 and Figure 3As shown, the inverted film application device also includes a pressure detection component 50, which is fixedly connected to the inverted module 20. The test surface of the pressure detection component 50 is set downwards. The transverse module 30 can drive the pressure detection component 50 to move above the pressure-receiving module 40, and the pressure-receiving module 40 can output an upward movement to press against the test surface of the pressure detection component 50. In other words, by setting the pressure detection component 50 and setting its test surface downwards, the pressure detection component 50 can simulate the lower surface of the product, thereby testing the pressure of the pressure-receiving component 43, ensuring that the pressure of the pressure-receiving component 43 on the film 62 and the product is appropriate, thus ensuring the reliability of the film 62 and avoiding damage to the product. Specifically, if the test result is within the preset pressure range, it means that the current pressure-receiving component 43 can provide a suitable pressure; if the test result is less than the preset pressure range, it means that the pressure is insufficient, which may cause the film 62 to be not firmly applied, and the pressure needs to be increased; if the test result is greater than the preset pressure range, it means that the pressure is too large, which may cause product damage, and the pressure needs to be decreased. It should also be noted that the pressure detection component 50 can be an existing pressure sensor.

[0031] In some embodiments, the stroke output of the pressing module 40 is adjustable to adjust the pressing force of the pressing component 43 on the product, so that the pressing force of the pressing module 40 on the film coating 62 is adjustable. Specifically, the output stroke of the lifting drive component 41 is adjustable, thereby enabling convenient and direct adjustment of the pressing force provided by the pressing component 43. Taking the lifting drive component 41 as a slide cylinder as an example, the stroke of the slide cylinder can be adjusted by adjusting its own stroke adjustment screw.

[0032] In some embodiments, in order to adjust the pressure exerted by the pressure-retaining component 43 on the product, such as Figure 3 and Figure 4 As shown, the inverted film applicator 20 includes a mounting plate 21 and a gripping mechanism 22. The mounting plate 21 is connected to the output end of the transverse module 30. The gripping mechanism 22 is mounted on the mounting plate 21 and is used to grip the product. The position of the gripping mechanism 22 relative to the mounting plate 21 in the vertical direction is adjustable. By adjusting the position of the gripping mechanism 22 in the vertical direction, the distance between the gripped product and the pressure-reducing component 43 can be adjusted. Thus, under the premise that the stroke output by the pressure-reducing module 40 is constant, the pressure applied by the pressure-reducing component 43 to the product can be adjusted. In addition, it should be noted that adjusting the position of the gripping mechanism 22 in the vertical direction also allows the inverted film applicator to be applicable to products of different thicknesses.

[0033] Specifically, such as Figure 4As shown, the inverted module 20 also includes a locking component 24 and a mounting structure 211. The mounting structure 211 is mounted on the mounting plate 21. One end of the locking component 24 is connected to the gripping mechanism 22, and the other end can be selectively connected to different positions on the mounting structure 211, thereby realizing vertical position adjustment between the gripping mechanism 22 and the mounting plate 21. In this embodiment, the mounting structure 211 includes multiple threaded holes spaced apart vertically. The locking component 24 is provided with a slotted hole 241. After the bolt passes through the slotted hole 241, it is threadedly connected to different threaded holes, which can flexibly adjust the position of the gripping mechanism 22 relative to the mounting plate 21 in the vertical direction. The structure is simple and the adjustment is convenient. In this embodiment, the inverted module 20 also includes a marking structure 212. The marking structure 212 is mounted on the mounting plate 21 and is used to mark the position of the locking component 24. By setting the marking structure 212, it can serve as a reference when the operator adjusts the gripping mechanism 22, thereby improving the convenience of adjusting the position of the gripping mechanism 22. Specifically, the marking structure 212 can be a scale line.

[0034] like Figure 4 As shown, the inverted module 20 also includes a second guide component 23. The gripping mechanism 22 is slidably engaged with the mounting plate 21 via the second guide component 23. The second guide component 23 can limit the movement direction of the gripping mechanism 22 relative to the mounting plate 21, ensuring more convenient and reliable adjustment of the vertical position of the gripping mechanism 22. Optionally, the second guide component 23 includes a second guide rail and a second slider. The second guide rail extends vertically and is fixed to the mounting plate 21. The second slider is fixedly connected to the gripping mechanism 22 and slidably engaged with the second guide rail.

[0035] like Figure 4 and Figure 5 As shown, the gripping mechanism 22 includes a support component 221 and several suction cups 222. The support component 221 slides vertically with the mounting plate 21. The suction cups 222 are all located on the lower side of the support component 221 and are connected to an external negative pressure mechanism. The suction cups 222 are configured to adsorb and fix the upper surface of the product. The vacuum adsorption of the suction cups 222 enables the gripping and fixing of the product, making it convenient to pick up and put down without easily damaging the product. It is understood that by adjusting the negative pressure value, the reliability of the product gripping can be ensured, preventing the product from loosening and falling off during the film application process. In this embodiment, four suction cups 222 are provided. In other embodiments, the specific number of suction cups 222 can be flexibly set according to needs. Furthermore, a channel can be provided inside the support component 221, with one end of the channel communicating with the suction cups 222 and the other end extending to the side of the support component 221 to facilitate connection with the external negative pressure mechanism.

[0036] like Figure 4 and Figure 5As shown, the support assembly 221 includes a connecting plate 2211 and an adjusting plate assembly 2212. The connecting plate 2211 is slidably engaged with the mounting plate 21 in the vertical direction. The adjusting plate assembly 2212 is slidably engaged with the connecting plate 2211 in a second horizontal direction, and a suction cup 222 is mounted on the adjusting plate assembly 2212. The gripping mechanism 22 also includes a micrometer adjusting assembly 2213, which connects the adjusting plate assembly 2212 and the connecting plate 2211. The micrometer adjusting assembly 2213 is configured to adjust the position of the adjusting plate assembly 2212 relative to the connecting plate 2211 in the second horizontal direction. In this embodiment, the positions of the connecting plate 2211 and the adjusting plate group 2212 along the second horizontal direction are adjustable. Combined with the adjustable position of the entire gripping mechanism 22 relative to the mounting plate 21 in the vertical direction, and the ability of the transverse module 30 to drive the entire inverted film application module 20 to be adjusted in the first horizontal direction, the position of the product gripped by the inverted film application module 20 relative to the feeder feeding module 10 can be flexibly adjusted, thereby enabling the inverted film application device to apply film to products of different sizes and models.

[0037] In this embodiment, as Figure 4 As shown, the connecting plate 2211 and the adjusting plate assembly 2212 are slidably engaged by a third guide component 223, which can specifically be a guide rail slider structure. It should also be noted that the micrometer adjusting component 2213 is an existing structure capable of fine-tuning the relative position of the two components; its specific structural details will not be elaborated upon here.

[0038] like Figure 5 As shown, a vertical positioning boss 2214 is provided on the lower side of the support component 221. The vertical positioning boss 2214 is configured to abut against the upper surface of the product, and the suction cup 222 is embedded in the vertical positioning boss 2214. On the one hand, the vertical positioning boss 2214 can correct the posture of the product, ensuring that the lower surface of the product is in a horizontal state, so as to facilitate smooth subsequent film application. On the other hand, the structure of the boss can reduce the area of ​​the surface that needs to be finely processed for positioning the product, thereby reducing the manufacturing cost of the support component 221. Furthermore, the suction cup 222 is embedded in the positioning boss, which can ensure that the suction cup 222 can reliably contact the upper surface of the product and achieve adsorption of the product.

[0039] like Figure 5As shown, a first positioning part 2215 and a second positioning part 2216 are also provided on the lower side of the support component 221. The first positioning part 2215 is configured to position the product along a first horizontal direction; the second positioning part 2216 is configured to position the product along a second horizontal direction. Through the first positioning part 2215 and the second positioning part 2216, the product's position in the horizontal plane can be positioned, thereby further ensuring the accuracy of the film 62's application position. In this embodiment, the first positioning part 2215 is constructed as a boss located at one end of the lower side of the adjustment plate assembly 2212 along the first horizontal direction, and the second positioning part 2216 is constructed as a boss located at the first end of the lower side of the adjustment plate assembly 2212 along the second horizontal direction.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, based on the concept of the present invention, there will be changes in specific implementation methods and application scope. The content of this specification should not be construed as a limitation of the present invention.
