Abstract
Description
Technical Field
[0001] The invention relates to the field of functional film production and processing, and in particular to a production device for a mobile phone camera lens functional film. Background Art
[0002] Functional film is a multifunctional smart film material with multiple functions such as heat insulation, UV protection, explosion protection, light adjustment, conductivity and decoration. It is widely used in many fields such as architectural glass, automotive glass, electronic displays and mobile phone camera lenses. For example, dimming film is also a kind of functional film. It is a special functional film material that can adjust the light transmittance. It is widely used in smart windows, automotive glass, electronic equipment screens and other fields. Its unique optical properties can be dynamically adjusted by changes in external voltage or ambient light. In recent years, as the requirements for optical performance of smartphone cameras have increased, functional films have been introduced into mobile phone camera lenses to achieve better light control and image quality optimization.
[0003] In the traditional functional film production process, the following main steps are usually included: First, the functional film needs to be cut according to the specific needs of the product. After cutting, the cut functional film is removed for subsequent processing, including applying silver paste on the surface of the film to achieve the conductive function. After the coating is completed, the film coated with silver paste needs to be baked to remove the moisture in the silver paste and solidify it. Finally, electrodes need to be made on the functional film to meet the electrical connection requirements. These processes need to be carried out in multiple steps, and each step needs to be precisely controlled.
[0004] However, in the production of functional films for mobile phone cameras, due to the small size of the camera, the volume of the functional film itself is very small, which brings significant challenges to the production process. Especially in the silver paste application process, due to the limited area of the film, manual application is difficult, which is not only inefficient, but also easily leads to uneven distribution of silver paste. In addition, during the manual application process, the functional film is small and difficult to handle, which further increases the complexity and inconvenience of the operation.
[0005] At the same time, because the traditional process requires cutting, silver paste coating, baking and electrode production to be completed step by step, the entire production process is lengthy, with many steps and significant inefficiency. This complex operation process not only increases production costs, but also reduces the yield rate, making it difficult to effectively meet the needs of large-scale production.
[0006] Therefore, in view of the problems existing in the traditional functional film production process such as low efficiency, uneven silver paste coating, and complicated operation, there is an urgent need for an efficient and integrated functional film production device that can realize the integration of cutting, silver paste coating, drying and material collection, especially for the optimized design of the tiny-sized functional films for mobile phone camera lenses, so as to improve production efficiency and product quality and meet the needs of modern electronic devices for high-performance functional films.

[0023] As a preferred technical solution, the material receiving and heating mechanism includes a double-headed cylinder, which is fixedly installed in the middle of the bottom surface of the installation cavity of the driving cylinder, and the driving rods on both sides of the double-headed cylinder are connected to a hinged bracket;
[0024] It also includes two material receiving boxes, which are located on both sides of the double-headed cylinder.

[0042] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.
[0043] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
[0044] like Figure 1-Figure 3 As shown, a production device for a functional film of a mobile phone camera lens of the present invention is described below with the functional film being a dimming film: comprising a driving cylinder 5, the driving cylinder 5 having a mounting cavity therein, a driving manipulator being mounted outside the driving cylinder 5, the driving manipulator driving the driving cylinder 5 to move horizontally along a working direction, the movement process of the driving manipulator being a linear horizontal movement, in order to install the driving manipulator, a fixing ring 7 is fixedly mounted outside the driving cylinder 5, a connecting bracket 8 is arranged on the fixing ring 7, so that the external driving manipulator can be connected to the connecting bracket 8, and the manipulator is used to drive the horizontal linear movement of the driving cylinder 5;
[0045] It also includes two processing wheels 9, which are rotatably mounted on both sides of the driving cylinder 5. When the driving cylinder 5 moves horizontally in the horizontal direction, the processing wheels 9 roll relative to the processing film 1 to be cut. A bearing can be installed between the processing wheels 9 and the driving cylinder 5, so that the processing wheels 9 can achieve better circumferential rotation relative to the driving cylinder 5 to reduce friction;
[0046] During processing, the processing film 1 to be cut is spread flat on two support tables, and there is a hollow area between the two support tables. The processing wheel 9 is in contact with the corresponding processing film. In this way, when the robot drives the driving cylinder 5 to move along the length direction of the processing film 1 to be cut, the processing wheel 9 can cut along the processing film 1 to be cut, and move forward in a rolling manner, which greatly improves efficiency and is very convenient to operate.
[0047] It also includes a central shaft 16, which is installed in the driving cylinder 5. The inner sides of the two processing wheels 9 are fixedly connected on both sides of the central cylinder. The two processing wheels 9 are connected by the central shaft 16 to achieve linkage. When driving, the driving cylinder 5 is in a horizontal state and does not rotate, and the processing wheels 9 roll forward along the processing film 1 to be cut.
[0048] The outer circumferential surface of each processing wheel 9 is provided with a plurality of processing contact surfaces 2 around the processing wheel 9, and each processing contact surface 2 is provided with a processing hole 3. A silicone contact layer can be provided on the processing contact surface 2 to increase the contact softness with the processing film 1 to be cut. Since a horizontal processing contact surface 2 is provided, each time the processing wheel 9 rotates, it can stop at the position of the processing contact surface 2 to complete the cutting positioning. A sensor, such as a pressure sensor, can be embedded in the processing contact surface 2 to generate a feedback signal when the processing contact surface 2 is in pressure contact with the processing film 1 to be cut.
[0049] Among them, a cutting mechanism is installed in each processing hole 3, and a silver paste feeding mechanism 4 is provided in each processing hole 3 located at the inner side end of the cutting mechanism. The lens film is cut out by the rolling movement of the processing wheel 9 on the processing film to be cut. When the processing wheel 9 rolls, the processing contact surface 2 contacts the processing film 1 to be cut, and the pressure sensor detects the pressure value and gives a feedback signal. At this time, the feedback signal can be transmitted to the control host. In this embodiment, the control host is installed at any position outside the driving cylinder 5, and the control host is used to drive the cutting mechanism at the bottom to perform the cutting action;
[0050] It also includes a plurality of telescopic adsorption mechanisms 6, one end of each telescopic adsorption mechanism 6 is fixedly mounted on the central axis 16, and each telescopic adsorption mechanism 6 is arranged corresponding to each of the processing holes 3; when the processing wheel 9 continuously rotates relative to the processing film 1 to be cut, the telescopic adsorption mechanism 6 at the bottom will extend downward by gravity until it contacts the processing film 1 to be cut, and then negative pressure adsorption is used to realize the retraction control of the telescopic adsorption mechanism 6, thereby sucking the cut functional film 100 into the processing wheel 9.
[0051] The processing film 1 to be cut is cut into a circular lens film by the cutting mechanism, the lens film is adsorbed by the telescopic adsorption mechanism 6, and the lens film is pulled into the processing wheel 9 in an arched state. During the pulling-in process of the lens film, the lens film is in an arched state and contacts the feeding surface 41 of the silver paste feeding mechanism 4 to realize the feeding of the silver paste on the lens film. After the feeding is completed, the lens film contacts the silver paste uniform material drying mechanism at the inner end and is dried and uniformly materialed once, such as Figure 7 As shown, since the lens film passes through a space smaller than its outer diameter during the suction process, it can maintain an arched state, so that it can better contact with the loading surface 41, thereby realizing a circle of silver paste loading on the lens film. After entering the processing wheel 9, it can contact with the silver paste uniform material drying mechanism to achieve the purpose of uniform material and preliminary drying.
[0052] like Figure 3 As shown, the silver paste uniform material drying mechanism is arranged at the outer end of the central axis 16. When the lens film is sucked into the processing wheel 9, the silver paste loading surface 41 of the lens film contacts the silver paste uniform material drying mechanism to achieve uniform material distribution and drying. The silver paste uniform material drying mechanism includes a fixed cylinder 18, which is installed on the outside of the central axis 16. The fixed cylinder 18 has openings corresponding to the positions of each of the telescopic adsorption mechanisms 6 and is provided with a uniform material drying cover 17. The uniform material drying cover 17 contacts the lens film to form a uniform material drying surface. A first heating component is embedded in the uniform material drying surface. The first heating component can be an electric heating wire embedded in the uniform material drying surface. A Teflon layer (polytetrafluoroethylene) can be provided on the surface of the uniform material drying cover 17 to reduce the adhesion of the silver paste, so that the functional film can be evenly contacted and separated from the uniform material drying cover 17 after the silver paste is applied, thereby effectively preventing adhesion. The silver paste that has been loaded can be flattened after contacting the uniform material drying surface, and the first heating component is used to achieve preliminary drying.
[0053] like Figure 3 and Figure 4As shown, the telescopic adsorption mechanism 6 is composed of more than one telescopic sleeves of different diameters, which are sealed and sleeved with each other. One end of the telescopic sleeve with the largest diameter is embedded in the central axis 16, and an adsorption head 62 is installed on the bottom end face of the telescopic sleeve with the smallest diameter. Each adsorption head 62 is provided with a negative pressure adsorption hole 61, and the negative pressure adsorption hole 61 is communicated with the inside of each telescopic sleeve. In order to ensure the sealing performance, a sealing piston can be provided on the pulling and stretching surface of each telescopic sleeve. When the negative pressure pump 12 is evacuated, each telescopic sleeve can be folded, the gas is extracted, and the adsorption head 62 can enter the processing wheel 9 with the functional film. Since the adsorption head 62 of the telescopic adsorption mechanism 6 at the bottom is in contact with the cut lens film, the negative pressure adsorption hole 61 is sealed by the functional film. At this time, the negative pressure pump 12 can adsorb the functional film by evacuating the air, and the telescopic adsorption mechanism 6 can be contracted and extended into the processing wheel 9 until the functional film contacts the material drying surface of the material drying cover 17.
[0054] Among them, Figure 3 As shown, the central axis 16 has a central cavity 14, and more than one suction pipe 15 is arranged in the central cavity 14, one end of each suction pipe 15 is connected to one end of the telescopic adsorption mechanism 6, and the other end of each suction pipe 15 is connected to a multi-way joint, and a negative pressure pump 12 is installed at the outer end of the multi-way joint. When the adsorption head 62 adsorbs the lens film, the negative pressure pump 12 generates negative pressure to adsorb the lens film and make each telescopic sleeve contract. The suction pipe 15 is equipped with a solenoid valve 26, and the adsorption head 62 is a metal counterweight block. A rubber contact layer is provided on one side of the negative pressure adsorption hole 61 of the adsorption head 62. When the processing contact surface 2 at the bottom contacts the functional film to be cut, the pressure feedback signal output by the pressure sensor is fed back to the control host. The control host controls each solenoid valve 26 to close, and the solenoid valve 26 at the bottom position is opened. At this time, the negative pressure pump 12 pumps air, and the gas in the bottom telescopic adsorption mechanism 6 can be pumped out through the bottom solenoid valve 26, so that the telescopic adsorption mechanism 6 and the functional film are retracted into the processing wheel 9. Since the adsorption head 62 is a metal block, the telescopic adsorption mechanism 6 at the bottom is stretched and descended under the action of gravity. Figure 2 and Figure 3 As shown, until the adsorption head 62 contacts the surface of the functional film to be cut, pressure induction is generated after contact to suck air to adsorb the functional film. Since the other solenoid valves 26 are closed, the telescopic adsorption mechanisms 6 at other positions will not be affected by the air extraction.
[0055] like Figure 4As shown, the silver paste feeding mechanism 4 includes a storage cavity 21 opened on the outer circumferential surface of each processing hole 3, and a counterweight ring 20 is arranged in the storage cavity 21. The inner circumferential surface of the processing hole 3 corresponds to the position of the storage cavity 21 to form a feeding surface 41, and one or more discharge holes 42 are arranged around the feeding surface 41. The silver paste is squeezed by the counterweight ring 20 and discharged from the discharge holes 42. When the counterweight ring 20 applies pressure to the silver paste due to the rotation of the processing wheel 9, the silver paste can be discharged from the discharge holes 42. The time spent on each step of the entire processing process of the present invention is fixed, that is, the time interval between each cutting, silver paste feeding, retracting and equalizing, and collecting is the same, and the time interval for each rolling angle of the processing wheel 9 for disassembly and cutting is also the same. Therefore, when the cut lens film passes through the feeding surface 41, the feeding amount of silver paste is guaranteed to be uniform as much as possible. Of course, slight differences do not affect it.
[0056] In order to allow the cut lens film to enter the loading surface 41 in an arched state for loading, in this embodiment, a conical guide surface 19 is formed in the processing hole 3 located at the outer end of the loading surface 41, and the cut functional film 100 enters the loading surface 41 through the conical guide surface 19. The cutting mechanism is located at the outer end of the conical guide surface 19, and the lens film forms an arched state after passing through the conical guide surface 19. Figure 7 As shown, when passing through the loading surface 41, the silver paste on the loading surface 41 can be loaded onto the lens film in a ring shape.
[0057] like Figure 4 As shown, the cutting mechanism includes an annular cutting knife, a circular cutting blade 25 is arranged at the bottom of the cutting knife, the cutting knife is installed in the tool installation cavity 23 opened in the processing wheel 9, and a mounting groove is arranged in the processing wheel 9 at the outer end of the tool installation cavity 23, and a telescopic motor 24 is installed in the mounting groove, and the driving end of the telescopic motor 24 is connected to the cutting knife, and the cutting knife and the circular cutting blade 25 are driven by the telescopic motor 24 to perform up and down lifting and cutting actions. When the cutting mechanism at the bottom is actuated, the cutting knife is driven down by the telescopic motor 24, and then the circular cutting blade 25 is used to perform circular cutting on the functional film to be cut, so as to obtain the required circular lens film, and each telescopic motor 24 is controlled by the control host, and when the pressure sensor gives a pressure feedback signal, the telescopic motor 24 at the corresponding position can be actuated.
[0058] like Figure 5 and Figure 6As shown, it also includes a material receiving and heating mechanism, which is installed at the bottom surface of the installation cavity of the driving cylinder 5, and is used to receive and perform secondary drying on the functional film after primary drying. The material receiving and heating mechanism includes a double-headed cylinder 32, which is fixedly installed at the middle position of the bottom surface of the installation cavity of the driving cylinder 5, and the driving rods on both sides of the double-headed cylinder 32 are connected to a hinged bracket 31;
[0059] It also includes two material receiving boxes 28, which are located on both sides of the double-headed cylinder 32. A hinged fixing plate 33 is provided on the material receiving box 28 on one side of the hinged bracket 31. The hinged bracket 31 is hinged to the hinged fixing plate 33 through a hinge shaft. A material collecting barrel 11 is provided at the bottom of the material receiving box 28, and a material collecting cavity 30 is provided in the material collecting barrel 11. A guide drying channel 29 is provided in each material receiving box 28, and one end of the guide drying channel 29 is communicated with the material collecting cavity 30. A threaded end cover 10 is provided at the bottom of the material collecting barrel 11, and a guide opening window 13 is provided on the bottom surface of the driving cylinder 5 corresponding to the material collecting barrel 11. The material collecting barrel 11 passes through the guide opening window 13 and extends to the outside of the driving cylinder 5.
[0060] When the functional film sucked into the processing wheel 9 is evenly distributed and dried once, the entire processing wheel 9 does not move in the circumferential direction. At this time, after 3-10 seconds, the cylinder can push out the receiving box 28, so that the receiving box 28 is pushed out and moved to the bottom of the functional film. At this time, the negative pressure pump 12 stops working, and the negative pressure disappears. The functional film after preliminary drying and even distribution can fall into the receiving box 28, and finally fall into the collecting chamber 30 after passing through the guide drying channel 29 for stacking and collection. When the receiving box 28 is pushed out and moves, the collecting barrel 11 will also move with it, that is, it can be guided in the guide switch window.
[0061] After the material receiving box 28 is reset, the driving cylinder 5 will move again, driving the processing wheel 9 to roll to the next station again, and repeat the above steps.
[0062] Among them, the receiving box 28 is provided with a feeding opening 27 on one side of the processing wheel 9, and the functional film falls into the feeding opening 27 after being separated from the telescopic adsorption mechanism 6, and the lens film can fall into the feeding opening 27 after picking up the negative pressure suction force, and the collection is completed;
[0063] In order to allow the lens film to slide into the collecting cavity 30 better along the inclined surface during the recycling process of the receiving box 28, in this embodiment, a support roller 34 is installed on the bottom of the receiving box 28 away from the double-headed cylinder 32. The support roller 34 is provided with a circle of concave and convex grooves. The bottom of the receiving box 28 rolls with the support roller 34. The supporting ball makes the receiving box 28 inclined. Under the influence of the support roller 34, the receiving box 28 vibrates when it retracts, thereby completing better material collection and providing a support to keep the receiving box 28 in an inclined state.
[0064] Among them, a second heating component is embedded in the diversion and drying channel 29 inside the material receiving box 28. The functional film flowing through the diversion and drying channel 29 is dried twice by the second heating component and then enters the collecting barrel 11. The second heating component and the first heating component can adopt the same structure. After passing through the diversion and drying channel 29, the lens film will be dried again to remove excess moisture.
[0065] The present invention uses the rolling forward mode of the processing wheel 9 to efficiently cut the lens film, which greatly improves the continuity and automation of the production operation. After the cutting is completed, the cut lens film is quickly adsorbed by the telescopic adsorption mechanism 6, and the lens film is arched through mechanical control to ensure that it is in full contact with the feeding surface 41 of the silver paste feeding mechanism 4;
[0066] The silver paste is precisely squeezed out through the discharge holes 42 on the feeding surface 41 and evenly adheres to the surface of the lens film. Subsequently, the lens film contacts the drying surface of the inner side and is pressed under force, and the silver paste coating is evenly coated and preliminarily dried during the contact process.
[0067] After the silver paste is evenly distributed and initially dried, the lens film is automatically transferred to the receiving and heating mechanism, and is subjected to secondary drying treatment by the automatic receiving device to completely remove residual moisture and volatiles. At the same time, the lens film is centrally collected, and the efficient drying and stable collection of the functional film is achieved through the double-headed cylinder 32 and the guide drying channel 29 in the receiving box 28.
[0068] The entire production process is integrated into one device, and multiple processes such as cutting, silver paste coating, drying, and material collection are completed in an integrated manner, which significantly improves production efficiency and avoids instability in manual operation. In particular, the functional film 100 after cutting is scraped when it is in an arch shape, and the coating is more uniform. It is also heated and dried by contact with the uniform material drying surface to ensure the consistency of silver paste distribution and adhesion quality. The device effectively solves the problems of complex operation, low efficiency, and uneven manual coating in traditional production processes, greatly improves the level of production automation, and is suitable for large-scale production of smartphone camera lens films.
[0069] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
