Description

Technical Field

[0001] This utility model relates to the technical field of membrane processing equipment, specifically to a device suitable for membrane preforming and lamination. Background Technology

[0002] Currently, there are various existing technical solutions in the field of membrane preforming and lamination technology.

[0003] In the existing technology, Solution 1 is a contact bonding method, which relies on direct contact bonding between the product platform and the membrane platform, and controls the bonding pressure by controlling the pressure of the membrane platform. This solution has extremely high requirements for the processing precision of the platform, and it is difficult to achieve a completely tight bonding for complex curved shapes. It is prone to defects such as wrinkles and bubbles. There is a high risk of stress concentration during the bonding process, which can easily damage the membrane material and the fixture. In addition, the fixture wears out quickly and has high maintenance costs.

[0004] Option 2 utilizes roll lamination, which involves controlling the rolling pressure and speed to bond the film material. This includes both roll lamination and vacuum lamination. Neither of these methods is suitable for laminating products with large curvature surfaces. Roll lamination requires high material hardness and compatibility; materials that are too soft or too hard will not achieve sufficient bonding strength. The process is complex, demands high levels of operator skill and experience, is difficult to control in terms of quality, and results in poor consistency. It is unsuitable for laminating complex shapes and large-sized products.

[0005] Option 3 is differential pressure bonding, which uses the stamping pressure of the sealed cavity to control the bonding pressure. However, the existing differential pressure bonding technology has limitations in application areas and cannot meet diverse production needs.

[0006] Therefore, it is necessary to design a device suitable for membrane preforming and lamination to solve the above-mentioned technical problems. Utility Model Content

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0044] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0045] Example 1: The specific structure of this utility model is as follows:

[0046] Please refer to the appendix. Figure 1-9 The present invention provides a device for preforming and bonding film materials, including a frame and a dual-station preforming and bonding mechanism disposed on the frame. The dual-station preforming and bonding mechanism includes a preforming lower cavity module 1 and a bonding lower cavity module 2, a first XY axis drive mechanism and a second XY axis drive mechanism that do not interfere with each other, a first upper cavity module 3, and a second upper cavity module 4.

[0047] The pre-formed lower cavity module 1 and the fitted lower cavity module 2 are arranged side by side. The pre-formed lower cavity module 1 has a lower cavity body, a manifold installed on the side of the lower cavity body and connected to the two ends of the lower cavity body through pipes, a vacuum controller 5 installed on the manifold and capable of controlling the pressure inside the lower cavity body, a positive pressure controller 6 installed on the manifold and capable of controlling the positive pressure of the lower cavity body, a vacuum gauge 7 installed on the manifold and capable of testing the vacuum inside the lower cavity body, a positive pressure gauge 8 installed on the side of the lower cavity body and capable of detecting the pressure inside the lower cavity body, and a membrane heating assembly 10 located inside the lower cavity body. The positive pressure controller 6 is connected to a positive pressure tank 21 through a pipe. The vacuum controller 5 is connected to a vacuum pump 20 through a pipe.

[0048] The membrane material is manually placed onto the top cover of the lower cavity body. The top cover of the lower cavity body is equipped with a heating tube 14 and a second thermocouple 13 for heat preservation. The membrane material heating assembly 10 is a ceramic heater. A vacuum ball valve module 9 is also connected to the side of the lower cavity body. The top of the lower cavity body has a second membrane material negative pressure hole, which is opposite to the first membrane material negative pressure hole. At least one mechanical positioning point 12 is located near the membrane material negative pressure hole, and multiple vacuum suction cups 11 arranged in a ring around the membrane material negative pressure hole. The mechanical positioning point 12 and the vacuum suction cups 11 ensure the installation accuracy and stability of the membrane material, preventing it from shifting as the lower cavity body moves. The temperature of the cavity cover surface is controlled by the heating tube 14 and the second thermocouple 13, maintaining a constant temperature for the cavity cover.

[0049] The membrane heating component 10 employs efficient infrared heating technology, enabling rapid and uniform heating of the membrane material to reach a suitable pre-forming temperature. Heating is conducted in a vacuum environment, further reducing environmental influences and improving the temperature uniformity of the entire membrane. The membrane heating component 10 uses closed-loop control; as it approaches the set temperature, it gradually reduces power to reach the set value, automatically maintaining a constant temperature upon reaching the set value, and automatically cutting off power if the temperature exceeds the set limit. The temperature of the membrane heating component 10 can be precisely adjusted according to the characteristics of different membrane materials, ensuring that the membrane is pre-formed at the set temperature.

[0050] Differential pressure control in vacuum and positive pressure control systems:

[0051] Vacuum: By adopting PID control technology combined with vacuum pump 20, vacuum controller 5, and vacuum gauge 7 to form a control closed loop, precise control of vacuum level can be achieved;

[0052] Positive pressure: By using PID control technology in combination with positive pressure tank 21, flow meter, and positive pressure gauge 8 to form a control closed loop, precise control of positive pressure can be achieved.

[0053] Example 2:

[0054] The lower cavity module 2 has a cavity body and a fixture assembly mounted on the cavity body. The fixture assembly includes a drive device 15 mounted on the cavity body and a fixture that is driven and connected to the drive device 15 and faces upward. The drive device 15 drives the fixture to move up and down. The cavity body is equipped with a vacuum and positive pressure control system, which is connected to a vacuum pump 20 via a pipeline.

[0055] Fixture Components: The design includes interchangeable fixtures of various shapes to meet the pre-forming requirements of different product shapes and sizes. The fixture surface undergoes fine polishing and anti-stick treatment to reduce friction between the product and the fixture, thereby reducing the risk of the film material being difficult to peel off from the fixture surface after lamination.

[0056] Drive unit 15: Driven by a high-precision servo motor combined with a high-reduction ratio reducer, it can precisely control the lifting height of the fixture and withstand bonding pressure exceeding several tons. During the bonding process, the lifting position can be freely set according to the thickness of the product and the fixture, so that the film material can accurately fit the shape of the product and achieve a high-quality bonding effect.

[0057] Differential pressure control in vacuum and positive pressure control systems:

[0058] Vacuum: By adopting PID control technology combined with vacuum pump 20, flow meter and vacuum gauge to form a control closed loop, the vacuum level can be precisely controlled.

[0059] Example 3:

[0060] The first upper cavity module 3 is mounted on the first XY axis drive mechanism, which can drive the first upper cavity module 3 to reach above the preformed lower cavity module 1.

[0061] The second upper cavity module 4 is mounted on the second XY axis drive mechanism, which can drive the second upper cavity module 4 to reach above the fitting lower cavity module 2;

[0062] The first upper cavity module 3 and the second upper cavity module 4 have the same structure, each having an upper cavity body, a first lifting device driven and connected to the upper cavity body, a mold head assembly disposed in the upper cavity body, and a mold head driving device 16 installed in the upper cavity body and driving the mold head assembly to perform lifting and lowering actions. The upper and lower plates of the upper cavity body each have through holes arranged coaxially, wherein the lower through hole is a first membrane material negative pressure hole, and the trajectory of the mold head assembly passes through the through hole. The mold head assembly is provided with a heater 17 composed of a heating tube group and a first thermocouple. The upper cavity body is also provided with a vacuum and positive pressure control system, which is connected to a vacuum pump 20 through a pipeline.

[0063] Die assembly: Designed with interchangeable molds of various shapes to meet the preforming needs of different product shapes and sizes. The molds are made of alloy materials, which have good thermal conductivity and wear resistance. The mold surface undergoes fine polishing to reduce friction between the film material and the mold, thereby reducing the risk of damage to the film material during the preforming process.

[0064] The mold head 26 is heated and controlled by heating tube assembly, thermocouple, and temperature controller, and the temperature difference can be controlled within ±1℃.

[0065] Water bath heating of the mold head (can be switched freely): The water temperature is precisely controlled by a mold temperature controller, which can quickly heat up and cool down the mold head 26. The temperature uniformity after stabilization is very high, which is suitable for solutions where the temperature uniformity requirements during the heating process are not high.

[0066] The die head drive device 16, driven by a high-precision servo motor combined with a high-reduction ratio reducer, can precisely control the lifting height of the die head 26 and withstand bonding pressure exceeding several tons. During the bonding process, the lifting position can be freely set according to the thickness of the die head, allowing the film material to accurately conform to the product shape and achieve a high-quality bonding effect.

[0067] Differential pressure control in vacuum and positive pressure control systems:

[0068] Vacuum: By using PID control technology combined with a vacuum pump, flow meter, and vacuum gauge to form a control closed loop, precise control of the vacuum level can be achieved;

[0069] Positive pressure: By using PID control technology combined with a positive pressure tank, flow meter, and positive pressure gauge to form a control closed loop, precise control of positive pressure can be achieved.

[0070] Example 4:

[0071] The frame is also equipped with two sets of XY axis motion mechanisms and CCD camera modules 18 that are driven one-to-one with the two sets of XY axis motion mechanisms. The movement trajectory of one set of CCD camera modules 18 can reach the film placement area of ​​the preformed lower cavity module 1, and the movement trajectory of the other set of CCD camera modules 18 can reach the fixture above the CCD camera module 18.

[0072] The CCD camera module 18 includes:

[0073] CCD camera 24 is mounted on the XY axis motion mechanism via a bracket;

[0074] Lens tube 23 connected to the lens end of the CCD camera 24;

[0075] Light source 22 connected to the bracket.

[0076] The CCD camera 24 uses an industrial CCD camera, which, together with the lens barrel 23 and the light source 22, ensures clear and reliable photography. Combined with preset MARK points and the vision system, it fine-tunes the pre-forming and bonding accuracy in the XY plane, ensuring accurate and reliable product pre-forming and bonding, and improving the product yield.

[0077] The frame is also equipped with a cleaning module 19. The cleaning module 19 uses both Plasma (plasma cleaning) and USC (dry ultrasonic cleaning) for dual cleaning, ensuring that the product surface is clean and dust-free, improving the quality of the product after membrane forming, and ensuring a high yield rate.

[0078] This invention also includes an electrical control system, which employs a programmable logic controller (PLC) for centralized control. The electrical control system collects parameters such as temperature, pressure, and position during equipment operation in real time through various sensors and transmits these parameters to the PLC for analysis and processing. Based on preset programs and parameters, the PLC automatically controls the actions of each actuator, achieving automated operation of the equipment. Operators can perform parameter settings, equipment monitoring, and fault diagnosis through the equipment's human-machine interface (HMI). The HMI interface features an intuitive and user-friendly design, making operation simple and convenient.

[0079] Example 5:

[0080] The following is the workflow of this utility model equipment: manual loading of material into the pre-forming lower cavity module 1; initial temperature setting and heat preservation of the cavity cover; fixation of the film material by mechanical positioning and vacuum suction cup holes of the cavity cover; CCD imaging and alignment confirmation and adjustment of the two upper cavity stations; movement of the upper cavity and the pre-forming lower cavity together to the pre-forming cavity closing position; simultaneous vacuuming of the upper and lower cavities; reaching the specified vacuum, infrared heating of the lower cavity is activated to heat the film material; heating to the specified temperature, the die head descends along the Z-axis (setting the initial heat preservation temperature); after descending to the surface of the film material, the lower cavity is filled with positive pressure; after reaching the specified positive pressure, pressure is maintained for a period of time; pressure holding ends, the lower cavity is depressurized, and the upper cavity remains vacuumed.

[0081] The aforementioned "alignment and adjustment of CCD imaging at two upper cavity workstations" refers to the installation of upper cavity CCD modules 25 at both upper cavity workstations. Figure 8 As shown, Figure 8 This diagram illustrates the installation positions of the two upper cavity CCD modules of this invention. One upper cavity CCD module 25 is used to photograph the #1 upper cavity mold head (MARK), and the other upper cavity CCD module 25 is used to photograph the #2 upper cavity mold head (MARK). They are paired with the two sets of CCD camera modules 18 in the lower cavity for fine-tuning of the structure. The upper cavity CCD module 25 relies on the X-axis movement of the upper cavity to fix the MARK point for photographing; CCD alignment adjustment ensures the pass rate and fitting accuracy of the cavity pre-forming.

[0082] Manual loading of material into the lower lamination fixture — CCD imaging for alignment and adjustment — USC and Plasma cleaning — Upper and lower lamination cavities moved to the mating position — Vacuuming of both cavities — Reaching the specified vacuum, the mold head 26 begins heating the membrane material — Heating to the specified temperature, the mold head drive device rises away from the membrane material — Fixture drive device lifts to the membrane material surface — After lifting into position, the upper cavity is filled with positive pressure — After reaching the specified pressure, pressure is maintained for a period of time — Pressure maintenance ends, the upper cavity is depressurized, and the lower cavity is de-vacuumed.

[0083] In summary, the equipment for membrane preforming and lamination of this invention enables high-precision pressure control. Vacuum control accuracy can reach ±1 Pa; the positive pressure control accuracy can reach ±0.1 kPa by combining a positive pressure gauge, flow meter, and positive pressure tank with a PID control system. This high-precision pressure control provides a precise and stable pressure environment for membrane preforming and lamination, avoiding poor lamination caused by unstable pressure, such as air bubbles and wrinkles, thus fundamentally ensuring lamination quality.

[0084] This invention relates to a device for preforming and laminating film materials, enabling highly efficient production. The device employs a dual-station design, allowing the preforming lower chamber and laminating lower chamber to operate simultaneously and independently without interference, thus shortening the production cycle. Furthermore, it can laminate multiple products in a single operation, significantly improving production efficiency compared to traditional single-station equipment. In large-scale production fields such as electronics and packaging, it can substantially increase production capacity and reduce production costs.

[0085] The equipment for membrane preforming and lamination of this invention can operate stably, which not only ensures the service life of the equipment itself, but also ensures the tightness and reliability of the membrane and product lamination under high pressure conditions.

[0086] This utility model is a device for preforming and bonding membrane materials. It can be used for bonding various curved and irregularly shaped products. By changing the fixture for the corresponding product, it can adapt to the needs of products with different shapes and sizes.

[0087] This invention relates to a device for preforming and laminating membrane materials, featuring a flexible heating system. The heating system comprises two sets: one is a heating tube assembly, ensuring high uniformity during the heating process and suitable for membrane materials requiring strict temperature uniformity; the other is a water bath heating system, offering rapid heating and high end-point uniformity, suitable for production scenarios where rapid heating is critical. The system can be quickly switched according to the characteristics of different membrane materials and production needs, ensuring that the membrane material reaches optimal temperature conditions during both preforming and lamination processes, further improving product quality and production efficiency.

[0088] This invention relates to a highly automated equipment for membrane preforming and lamination: once the process parameters are determined, the equipment can operate automatically. The electrical control system uses a programmable logic controller (PLC) for centralized control, collecting parameters such as temperature, pressure, and position in real time and automatically controlling the actions of each actuator. This not only reduces errors from manual operation, ensuring product consistency and improving product quality stability, but also reduces reliance on operator skills and experience, making operation simpler and more convenient, and lowering the company's human resource training costs and production management difficulties.
