Description

Technical Field

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

[0002] Nowadays, after products are processed, such as tablets and mobile phones, a protective film is usually applied around the product using a film application device.

[0003] When applying film to products, the laminating equipment first uses a laser component to create pre-set holes in the protective film to correspond to the product's raised structures, such as volume buttons, power buttons, and LEDs. The protective film is then applied to the base film, which is then wound onto the film supply unit. Next, the film supply unit feeds the film onto the drive mechanism, separating the base film and protective film, and winding the base film onto the take-up unit. Finally, the protective film is applied to the side wall of the workpiece on the carrier assembly. The carrier assembly then rotates under the drive of the rotating component to apply the protective film to the periphery of the workpiece. The operator then uses a cutter to cut the protective film, completing the laminating process. However, this laminating device is complex to operate, reducing efficiency. Furthermore, the base film needs to be used in conjunction with the protective film, and a take-up unit is required to collect discarded base film. The laminating equipment also occupies a large space, resulting in high operating costs. Utility Model Content

[0004] In view of the above situation, it is necessary to provide a film application device to improve film application efficiency at a low cost.

[0005] Some embodiments of this application provide a film-applying device, including a machine base, a film supply assembly, a clamping assembly, a processing assembly, a carrying assembly, and a film-applying assembly. The machine base has a main shaft. The film supply assembly includes a support member and two limiting members. The support member is configured to wind the film body. The two limiting members are located on both sides of the support member and connected to it respectively. Each limiting member has a through hole, and a limiting groove is formed between the two limiting members and the support member, the limiting groove being configured to limit the film body. The clamping assembly is located on the machine base and inserted into the through hole. The clamping assembly is configured to drive the film supply assembly to rotate the film body. The processing assembly is connected to the main shaft and is used to process the film body wound onto the support member. The carrying assembly is located on the machine base and positioned on one side of the clamping assembly. The carrying assembly is configured to carry a workpiece and drive the workpiece to rotate. The film-applying assembly is located on the machine base and positioned close to the carrying assembly. The film-applying assembly is used to attach the film body to the side wall of the workpiece, so that the workpiece drives the film body to rotate, thereby adhering the film body to the periphery of the workpiece.

[0006] In operation, the aforementioned film-applying device first winds the film onto the support member. The limiting groove formed between the two limiting members and the support member limits the film and prevents misalignment between the film and the support member. Then, after the film is wound, the clamping component is inserted into the through hole and clamps with the two limiting members respectively. The clamping component drives the support member to rotate the film, so that the processing component connected to the spindle processes the film, creating multiple preset holes on the film. Finally, the film-applying component adsorbs the end of the film and moves the film to the workpiece carried by the bearing component. The end of the film is then attached to the side wall of the workpiece. Next, the bearing component drives the workpiece to rotate synchronously with the end of the film, so that the remaining film is completely wrapped around the periphery of the workpiece. At the same time, the preset holes on the film avoid the preset areas on the workpiece. The spindle then drives the processing component to cut the film attached to the workpiece. The film-applying device integrates the film supply assembly, clamping assembly, processing assembly, carrying assembly, and film-applying assembly onto the machine base. This prevents the film-applying equipment from occupying excessive space and avoids the need for a base film to support the film. Simultaneously, the machine base's spindle is connected to the processing assembly, driving its movement for processing and film-cutting operations. This eliminates the need for additional drive mechanisms, reducing operating costs. By centralizing film processing and film-applying operations within the machine base, the film-applying process is simplified, improving efficiency while maintaining low cost. Furthermore, by using processing components (such as milling cutters) instead of traditional laser punching technology, multiple layers of perforation on a single roll of film can be completed sequentially, improving perforation efficiency. Moreover, the film does not require a base film for reinforcement, reducing waste and saving costs.

[0007] In some embodiments, the limiting member includes a linkage body, a limiting body, and a plurality of connecting bodies. The linkage body has a through hole and is used to engage with a holding assembly. The limiting body is sleeved on the linkage body and connected to a support member, and is configured as a limiting membrane. The plurality of connecting bodies are spaced apart circumferentially along the linkage body, and each connecting body has its two ends connected to the linkage body and the limiting body, respectively.

The other end of the locking part abuts against the side of the limiting part away from the support member.

[0010] In some embodiments, the support member has a plurality of clearance holes, which are spaced apart circumferentially along the support member, and the clearance holes are configured as clearance processing components.

[0011] In some embodiments, the support member is provided with a plurality of anti-slip grooves, which are equally spaced along the circumference of the support member on the side wall of the support member.

[0012] In some embodiments, the bearing assembly includes a rotary drive, a bearing member, and a clamping member. The rotary drive is located on one side of the clamping assembly and connected to the machine base. The bearing member is connected to the rotary drive and has a bearing position configured to bear a workpiece. The bearing member is used to drive the workpiece to rotate under the drive of the rotary drive. The clamping member is located near the bearing position and connected to the bearing member. The clamping member is configured to clamp the workpiece.

[0013] In some embodiments, the clamping member includes a clamping body and an elastic body. The clamping body is slidably disposed on one side of the bearing position, and the two ends of the elastic body elastically abut against the clamping body and the bearing member, respectively. The elastic body is configured to push the clamping body to clamp the workpiece.

[0014] In some embodiments, the carrier assembly further includes a positioning element, which is disposed at the carrier position and connected to the carrier assembly. The positioning element is used to be inserted into the workpiece to position the workpiece.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features.

[0022] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection or a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above term in this application according to the specific circumstances.

[0023] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0024] Please see Figure 1 This application provides a film-applying device 100, which includes a film supply assembly 10, a holding assembly 20, a processing assembly 30, a carrying assembly 40, a film-applying assembly 50, and a machine base 60. The film-applying device 100 is used to apply a film to the periphery of a workpiece. The workpiece can be a mobile phone, tablet computer, etc., and the film can be any film that can be applied to the periphery of the workpiece, such as a release film.

[0025] Please see Figure 1 and Figure 2The machine base 60 has a main shaft 61. The film supply assembly 10 includes a support member 11 and two limiting members 12. The support member 11 is annular and configured to wind the film body. The two limiting members 12 are located on both sides of the support member 11 and connected to it respectively. Each limiting member 12 has a through hole 121. A limiting groove 13 is formed between the two limiting members 12 and the support member 11, and the limiting groove 13 is configured to limit the film body. A clamping assembly 20 is located on the machine base 60 and inserted into the through hole 121. The clamping assembly 20 is configured to drive the film supply assembly 10 to rotate the film body. A processing assembly 30 is connected to the main shaft 61 of the machine base 60 and is used to process the film body wound on the support member 11. A carrying assembly 40 is located on the machine base 60 and is located on one side of the clamping assembly 20. The carrying assembly 40 is configured to carry the workpiece and drive the workpiece to rotate. The film-applying assembly 50 is mounted on the machine base 60 and positioned close to the support assembly 40. The film-applying assembly 50 is used to attach the film to the side wall of the workpiece, causing the workpiece to rotate and thus adhere the film to the periphery of the workpiece. Exemplarily, the clamping assembly 20 can be any clamping member, clamping part, or similar clamping body capable of clamping the support member 11 and causing it to rotate, such as a three-jaw chuck connected to a rotary cylinder. The processing assembly 30 can be any processing part, processing section, or similar processing body capable of processing the film, such as a milling cutter connected to the spindle 61. The machine base 60 can be a CNC machine base (Computer Numerical Control).

[0026] In operation, the film-applying device 100 first wraps the film around the support member 11. The limiting groove 13 formed between the two limiting members 12 and the support member 11 limits the film and prevents misalignment between the film and the support member 11. Then, after the film is wrapped, the clamping component 20 is inserted into the through hole 121 and clamps the two limiting members 12 respectively. The clamping component 20 drives the support member 11 to rotate the film so that the processing component 30 connected to the spindle 61 processes the film, so that multiple preset holes are opened on the film. Finally, the film-applying component 50 adsorbs the end of the film and moves the film to the workpiece carried by the bearing component 40. Then, the end of the film is attached to the side wall of the workpiece. Then, the bearing component 40 drives the workpiece to rotate synchronously with the end of the film so that the rest of the film is completely wrapped around the periphery of the workpiece. At the same time, the preset holes on the film avoid the preset area on the workpiece. The spindle 61 then drives the processing component 30 to cut the film attached to the workpiece. The film-applying device 100, by integrating the film supply assembly 10, holding assembly 20, processing assembly 30, carrying assembly 40, and film-applying assembly 50 onto the machine base 60, prevents the film-applying equipment from occupying excessive space and avoids the need for a base film to support the film. Simultaneously, the main shaft 61 of the machine base 60 is connected to the processing assembly 30, driving the processing assembly 30 to perform processing and film-cutting operations. This eliminates the need for other drive mechanisms, reducing operating costs. By concentrating film processing and film-applying operations within the machine base 60, the film-applying process is simplified, achieving improved efficiency at a lower cost. Furthermore, by using the processing assembly 30 (such as a milling cutter) instead of traditional laser punching technology, multiple layers of perforation on a roll of film can be completed sequentially, improving perforation efficiency. Moreover, the film does not require a base film for reinforcement, reducing waste of the base film itself and saving costs.

[0027] It should be noted that the aforementioned preset holes can be of the same type or different types.

[0028] Please see Figure 1 and Figure 2 In some embodiments, the limiting member 12 includes a linkage body 122, a limiting body 123, and a plurality of connecting bodies 124. The linkage body 122 has a through hole 121 and is used to hold the linking assembly 20. The limiting body 123 is sleeved on the linkage body 122 and connected to the support member 11, and the limiting body 123 is configured as a limiting membrane. The plurality of connecting bodies 124 are arranged at intervals along the circumference of the linkage body 122, and the two ends of each connecting body 124 are connected to the linkage body 122 and the limiting body 123, respectively.

[0029] By setting multiple connectors 124 spaced circumferentially along the linkage 122, with each connector 124 connected to the linkage 122 and the limiting body 123 at both ends, the structure of the limiting member 12 can be optimized. While ensuring the structural strength of the limiting member 12, the weight of the limiting member 12 can be reduced, thereby significantly reducing the overall weight of the film supply assembly 10. This is beneficial for the clamping assembly 20 to stably drive the limiting member 12 to drive the support member 11 and the membrane to rotate.

[0030] Please see Figure 2 In some embodiments, the wall of the through hole 121 is provided with a receiving groove 125, and the limiting member 12 also includes a supporting body 126. The supporting body 126 is inserted into the receiving groove 125 and abuts against the holding component 20. The supporting body 126 is configured to limit the linkage body 122.

[0031] By holding the abutment 126 with the clamping component 20 and the linkage 122 respectively, the linkage 122 is restricted from rotating relative to the clamping component 20, preventing the linkage 122 and the clamping component 20 from slipping against each other, ensuring that the clamping component 20 stably drives the limiting component 12 to rotate, thereby improving the stability of film supply.

[0032] Please see Figure 2 In some embodiments, the limiting body 123 includes a limiting portion 1231 and a locking portion 1232. The limiting portion 1231 is disposed on one side of the support member 11 and is respectively connected to a plurality of connecting bodies 124. One end of the locking portion 1232 is movably inserted through the limiting portion 1231 and threadedly connected to the support member 11, while the other end of the locking portion 1232 abuts against the side of the limiting portion 1231 opposite to the support member 11. Exemplarily, the locking portion 1232 can be a bolt.

[0033] By setting one end of the locking part 1232 to be movably inserted through the limiting part 1231 and threadedly connected to the support member 11, a split structure can be formed between the limiting member 12 and the support member 11, which makes it easy to adjust the distance between the two limiting bodies 123 according to the usage requirements, so as to adapt to membranes of different widths and improve adaptability.

[0034] Please see Figure 2 In some embodiments, the support member 11 has a plurality of clearance holes 111, which are spaced apart along the circumference of the support member 11, and the clearance holes 111 are configured as clearance processing components 30.

[0035] The processing component 30 can be bypassed by the clearance hole 111, so that the processing component 30 can directly process the membrane wound on the support member 11 under the drive of the spindle 61, without having to remove the membrane or set up a separate processing position, thereby reducing the cost of use and improving the processing efficiency of the membrane.

[0036] Please see Figure 2In some embodiments, the support member 11 is provided with a plurality of anti-slip grooves 112, which are equally spaced along the circumference of the support member 11 on the side wall of the support member 11.

[0037] The anti-slip groove 112 can increase the friction between the membrane and the support member 11, preventing the membrane from slipping or stacking when the support member 11 rotates, ensuring constant membrane tension, avoiding membrane deviation, and thus ensuring the processing accuracy and application accuracy of the membrane.

[0038] Please see Figure 1 and Figure 3 In some embodiments, the supporting assembly 40 includes a rotary drive 41, a supporting member 42, and a clamping member 43. The rotary drive 41 is disposed on one side of the clamping assembly 20 and connected to the machine base 60. The supporting member 42 is connected to the rotary drive 41 and has a supporting position 421, which is configured to support a workpiece. The supporting member 42 is used to drive the workpiece to rotate under the drive of the rotary drive 41. The clamping member 43 is disposed near the supporting position 421 and connected to the supporting member 42. The clamping member 43 is configured to clamp the workpiece. Exemplarily, the rotary drive 41 can be a rotary cylinder, a motor, etc.

[0039] After the workpiece is placed on the bearing position 421, the clamping member 43 clamps and fixes the workpiece located on the bearing position 421 to prevent the workpiece from shaking or falling during rotation, so that the rotation drive member 41 can stably drive the bearing member 42 to rotate the workpiece, thereby improving the stability of film application.

[0040] Please see Figure 3 In some embodiments, the clamping member 43 includes a clamping body 431 and an elastic body 432. The clamping body 431 is slidably disposed on one side of the bearing position 421, and the two ends of the elastic body 432 elastically abut against the clamping body 431 and the bearing member 42, respectively. The elastic body 432 is configured to push the clamping body 431 to clamp the workpiece. Exemplarily, the elastic body 432 may be a spring.

[0041] The elastomer 432 can push the clamping body 431 to flexibly clamp the workpiece, avoiding damage to the workpiece and thus ensuring the product quality and aesthetics of the workpiece.

[0042] Please see Figure 3 In some embodiments, the support assembly 40 further includes a positioning member 44, which is disposed at the support position 421 and connected to the support member 42. The positioning member 44 is used to be inserted into the workpiece to position the workpiece.

[0043] The positioning element 44 is inserted into the workpiece to position the workpiece so that the workpiece maintains a preset orientation and position on the bearing position 421, avoiding workpiece displacement, thereby ensuring that the film is accurately attached to the periphery of the workpiece, thus improving the film application accuracy.

[0044] Please see Figure 1 In some embodiments, the film application assembly 50 includes a transfer member 51 and a film suction member 52. The transfer member 51 is disposed on the machine base 60 and located near the support assembly 40. The film suction member 52 is connected to the transfer member 51 and is configured to suction the film, moving between the film supply assembly 10 and the support assembly 40 under the drive of the transfer member 51. Exemplarily, the transfer member 51 may be a robotic arm, a four-axis linkage mechanism, etc., and the film suction member 52 may be any film suction body, film suction section, or similar suction head capable of suctioning the film.

[0045] The film is adsorbed by the suction member 52 and moves between the film supply assembly 10 and the carrier assembly 40 under the drive of the transfer member 51 to complete the film application operation. This eliminates the need for the operator to attach the end of the film to the side wall of the workpiece, thereby improving the film application efficiency.

[0046] The working process of the above-mentioned film application device 100 is roughly as follows: First, the membrane is wound onto the support member 11. The distance between the two limiting members 12 is adjusted according to the width of the membrane. Then, the two limiting members 12 are respectively locked to both sides of the support member 11, so that the limiting groove 13 formed between the two limiting members 12 and the support member 11 limits the membrane and prevents misalignment between the membrane and the support member 11. Then, after the membrane is wound, the clamping component 20 is inserted into the through hole 121 and engaged with the two limiting members 12 respectively. The clamping component 20 drives the support member 11 to rotate the membrane, so that the processing component 30 connected to the spindle 61 processes the membrane, thereby opening multiple preset holes on the membrane. By using the processing component 30 (such as a milling cutter) to replace the traditional laser punching hole-opening technology, multiple layers of holes on a roll of membrane can be opened sequentially, improving hole-opening efficiency. Moreover, the membrane does not need to use a bottom film reinforcement, reducing the waste of the bottom film itself and saving costs. Finally, the film-applying assembly 50 attaches the end of the film to the side wall of the workpiece, and the carrying assembly 40 drives the workpiece to rotate so that the film is completely wrapped around the periphery of the workpiece. At the same time, the preset holes on the film avoid the preset areas on the workpiece. The processing assembly 30 then cuts the film attached to the workpiece. The film-applying device 100, by setting the film supply assembly 10, the clamping assembly 20, the processing assembly 30, the carrying assembly 40, and the film-applying assembly 50 on the machine base 60, prevents the film-applying equipment from occupying too much space and avoids the use of a base film to support the film. At the same time, the main shaft 61 of the machine base 60 is connected to the processing assembly 30 and drives the processing assembly 30 to move to perform processing and film cutting operations. No other driving mechanism is needed, which reduces the cost of use. The film processing and film-applying operations are concentrated in the machine base 60, simplifying the film-applying process and improving film-applying efficiency at a low cost.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
