Description

Technical Field

[0001] This utility model relates to the field of lamination equipment technology, and in particular to a multi-layer laminator with multiple independent structures. Background Technology

[0002] Laminators are indispensable key equipment in modern industrial production, especially in the fields of photovoltaics, electronic circuits and composite material manufacturing, where they are used to press multiple layers of materials together under heating, pressure and vacuum conditions.

[0003] As products evolve towards higher density, higher integration, and greater multifunctionality, the demand for multilayer lamination processes is increasing. Unlike single-layer lamination, multilayer structures place more stringent requirements on the process window, demanding not only high-precision material alignment but also precise control over the vacuum environment and temperature uniformity of different layers or regions.

[0004] Existing multilayer laminators often employ integrated or non-independent control systems in their structural design. For example, their material conveying mechanisms have poor synchronization, which can easily lead to positional deviations when stacking multiple layers of material. At the same time, their vacuum and heating systems typically handle the entire lamination chamber uniformly, lacking independent control capabilities.

[0005] This "non-independent" structural design results in poor flexibility of the equipment when handling complex lamination tasks. It is unable to achieve differentiated and precise control for different material layers or different process areas, which ultimately leads to defects such as bubbles, delamination, or misalignment in laminated products, making it difficult to meet the production requirements of high-quality multilayer products.

[0006] Therefore, this utility model proposes a multi-independent structure multi-layer laminator to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems existing in the multi-independent structure multi-layer laminator, such as poor synchronization of material conveying mechanism leading to positioning deviation, and lack of independent control capability of vacuum system and heating system leading to imprecise process control, this utility model aims to provide a multi-independent structure multi-layer laminator with improved structure that can effectively solve the above problems.

[0008] This utility model provides a multi-independent structure multi-layer laminator, including: a support frame, and a transmission mechanism, a vacuum mechanism and a lamination heating mechanism installed on the support frame.

[0009] The lamination heating mechanism is located in the middle of the support frame, the transmission mechanism spans above the lamination heating mechanism, and the vacuum mechanism is integrated into the lamination heating mechanism.

[0010] The transmission mechanism includes a drive assembly, a drive gear, a driven gear, a first rotating column, and a second rotating column. The output end of the drive assembly is fixedly connected to a drive shaft, which drives the drive gear to rotate. The drive gear meshes with the driven gear. The drive gear is fixedly connected to one end of the first rotating column, and the driven gear is fixedly connected to one end of the second rotating column.

[0011] The vacuum mechanism includes an upper vacuum unit, a lower vacuum unit, an upper butterfly valve, a lower butterfly valve, a vacuum port, and a vacuum tube. The upper vacuum unit is connected to the vacuum tube via an upper butterfly valve installed on the pipeline, and the lower vacuum unit is connected to the vacuum tube via a lower butterfly valve installed on the pipeline.

[0012] The lamination heating mechanism includes a heating base plate, a temperature control plate, and heat-conducting columns. Vacuum holes are opened on the upper surface of the heating base plate and are connected to vacuum tubes. Heat-conducting columns are inserted into the heating base plate. The temperature control plate is electrically connected to the heating base plate to control the temperature.

[0013] Preferably, the drive assembly includes a servo motor, the output shaft of which is fixedly connected to the drive shaft. The servo motor is fixedly mounted on the side wall of the support frame, and the servo motor provides high-precision rotation control for the drive shaft.

[0014] Preferably, rotating column one and rotating column two extend along the material conveying direction and are arranged parallel to each other, jointly defining the material conveying channel. The conveying channel is located directly above the heating base plate. This parallel synchronous rotating column structure ensures that the material is subjected to uniform force and has a stable path during the conveying process.

[0015] Preferably, the vacuum tube includes a main pipe and multiple isolated branch pipes branching off from the main pipe. Each branch pipe is connected to a vacuum hole in the corresponding laminated area. This structural design is the physical basis for achieving independent control of multi-layer vacuum.

[0016] Preferably, the heating base plate has multiple arrayed heat-conducting holes and multiple heat-conducting columns, which are installed in close fit within the heat-conducting holes. The arrayed heat-conducting columns enable rapid and uniform diffusion of heat from the heat source to the working surface of the heating base plate.

[0017] Preferably, the temperature control plate integrates a temperature sensing module. The probe of the temperature sensing module is placed on the surface of the heating base plate to detect the actual temperature of the working area of ​​the heating base plate in real time and feed it back to the temperature control plate to form a closed-loop temperature control.

[0018] Preferably, it also includes an iron plate and a welding block, wherein the iron plate serves as the supporting substrate of the lamination heating mechanism, providing a flat and highly rigid mounting base for the heating base plate.

[0019] Preferably, there are multiple welding blocks, which are spaced apart and welded to the support frame. The iron plate is fixed to the support frame by welding the welding blocks. This welding method provides a strong connection and strong structural support.

[0020] This utility model has the following beneficial effects: 1. This utility model solves the problems of material slippage, inaccurate positioning, or inconsistent speeds on both sides during material conveying in the prior art by setting a drive shaft driven by a servo motor, which drives the active gear to rotate and the active gear meshes with the driven gear. The active gear and the driven gear are respectively fixedly connected to rotating column one and rotating column two. This achieves the technical effect of accurately controlling the start and stop of material conveying, ensuring the stability of material conveying and the accuracy of positioning.

[0021] 2. This utility model solves the problem of uneven surface temperature distribution and large local temperature difference caused by uneven heat conduction path in the existing technology of large-area heating base plates by opening multiple heat conduction holes and inserting heat conduction columns into the heat conduction holes. The heat is evenly conducted inside the heating base plate through the heat conduction columns. This achieves the technical effect of fast heat transfer and uniform heating, thereby significantly improving the quality and consistency of multi-layer material lamination.

[0022] 3. This utility model solves the problem in the prior art that the vacuum system of the laminator is uniformly controlled and cannot independently and precisely regulate the vacuum environment of multi-layer structures or different areas by setting up an upper vacuum device and a lower vacuum device, and controlling the independent vacuum pipeline connected to the vacuum hole through the upper butterfly valve and the lower butterfly valve respectively. It achieves the technical effect of being able to independently evacuate different lamination areas and flexibly control the vacuum sequence and vacuum degree, thereby improving the flexibility of the process and the adaptability to complex products.

[0023] 4. This utility model solves the problem of structural deformation or vibration that may occur in the equipment under high-temperature working environment due to an unstable foundation by setting welding blocks to weld and fix the iron plate to the support frame, and uses the iron plate as the load-bearing base plate of the lamination heating mechanism. It achieves the technical effect of enhancing the rigidity of the whole machine structure, improving the load-bearing capacity and operational stability of the equipment. Attached Figure Description

[0026] Example: Reference Figures 1 to 4 This utility model provides a multi-independent structure multi-layer laminator, which aims to solve the problems of insufficient material conveying and positioning, insufficient independent vacuum environment control in each lamination area, and unstable lamination quality caused by uneven temperature distribution of heating plates in the existing multi-layer laminator.

[0027] like Figure 1 As shown, the multi-layer laminator with independent structure includes a support frame 1, and a transmission mechanism 2, a vacuum mechanism 3, and a lamination heating mechanism 4 mounted on the support frame 1. The lamination heating mechanism 4 is located in the middle of the support frame 1, serving as the core working area of ​​the entire equipment. The transmission mechanism 2 spans above the lamination heating mechanism 4 for material feeding and conveying. The vacuum mechanism 3 is integrated into the lamination heating mechanism 4 to create a vacuum environment during the lamination process. The lamination heating mechanism 4 specifically includes a heating base plate 41, a temperature control plate 42, and heat-conducting columns 43. The temperature control plate 41... 2 is electrically connected to the heating base plate 41 for precise temperature control of the heating base plate 41. The heat-conducting column 43 is inserted into the heating base plate 41 to achieve uniform heat conduction. The vacuum hole 35 of the vacuum mechanism 3 is opened on the upper surface of the heating base plate 41, so that the vacuum environment can directly act on the lamination working area. The rotating column 1 24 and rotating column 25 of the transmission mechanism 2 are arranged parallel to each other directly above the heating base plate 41. The two together define the material conveying channel to ensure that the material can be accurately conveyed to the lamination position above the heating base plate 41.

[0028] Reference Figure 2 and Figure 3The drive assembly 21 of the transmission mechanism 2 includes a servo motor 211 and a drive shaft 212. The servo motor 211 is fixedly mounted on the side wall of the support frame 1, and its output shaft is fixedly connected to the drive shaft 212. The output end of the drive shaft 212 is fixedly connected to the drive gear 22, thereby accurately transmitting the rotational power of the servo motor 211 to the drive gear 22. The drive gear 22 and the driven gear 23 are connected by meshing. The drive gear 22 is fixedly connected to one end of the rotating column 24 by a key or by integral forming. 23 is also fixedly connected to one end of the rotating column 25. Due to the characteristics of gear meshing transmission, the rotation of the driving gear 22 will drive the driven gear 23 to rotate synchronously in the opposite direction, thereby enabling the rotating column 24 and the rotating column 25 to rotate synchronously. The rotating column 24 and the rotating column 25 extend along the material conveying direction and are set parallel to each other, jointly defining the material conveying channel. This transmission structure, which is precisely driven by the servo motor 211 and synchronized by the gear set, ensures the stability and positioning accuracy of the material during the conveying process.

[0029] Reference Figure 4 The vacuum tube 36 of the vacuum mechanism 3 includes a main pipe and multiple isolated branch pipes branching off from the main pipe. Each branch pipe is connected to the vacuum hole 35 of the corresponding lamination area. The upper butterfly valve 33 and the lower butterfly valve 34 control the opening and closing of different branch pipes, thereby realizing the function of partitioning or layering vacuuming. The heating base plate 41 has multiple arrayed heat conduction holes to improve the temperature uniformity and heat transfer efficiency of the heating base plate 41. There are multiple heat conduction columns 43, and the heat conduction columns 43 and the corresponding heat conduction holes are installed in a tight fit. The high thermal conductivity of the heat conduction columns 43 allows heat to be quickly and evenly diffused to the entire working surface of the heating base plate 41. The temperature control plate 42 integrates a temperature sensing module. The probe of the temperature sensing module is placed on the surface of the heating base plate 41 to collect the surface temperature data of the heating base plate 41 in real time and feed it back to the temperature control plate 42 for processing, so as to realize precise closed-loop control of the lamination temperature. It also includes an iron plate 5 and welding blocks 6. The iron plate 5 serves as the supporting substrate of the lamination heating mechanism 4. There are multiple welding blocks 6. These welding blocks 6 are distributed at intervals and are first fixedly connected to the support frame 1 by welding. Then, the iron plate 5 is fixedly connected to the top surface of these welding blocks 6 by welding, which enhances the structural stability and load-bearing capacity of the entire device.

[0030] The working principle is as follows: When lamination is required, the servo motor 211 in the drive assembly 21 starts, and its rotational motion is transmitted to the drive gear 22 through the drive shaft 212. The drive gear 22 meshes with the driven gear 23, which drives the driven gear 23 to rotate synchronously. This drives the rotating column 24 and rotating column 25, which are fixedly connected to the gear, to rotate synchronously, accurately conveying the material to be laminated to the working area above the heating base plate 41 of the lamination heating mechanism 4.

[0031] After the materials are in place, the vacuum mechanism 3 starts working. The upper vacuum device 31 and the lower vacuum device 32 start evacuating air, and the upper butterfly valve 33 and the lower butterfly valve 34 open. Air is extracted through the vacuum hole 35 opened on the heating base plate 41 and flows into the main pipe through the branch pipe of the vacuum pipe 36, forming the required vacuum environment in the lamination area. At the same time, the lamination heating mechanism 4 starts, and the heating base plate 41 generates heat. The heat is quickly and evenly conducted to the entire surface of the heating base plate 41 through the tightly fitted array of heat-conducting columns 43 inside. The temperature control plate 42 monitors and precisely maintains the lamination temperature in real time through its temperature sensing module.

[0032] Under precise vacuum environment and uniform and stable high temperature, the material completes the lamination process. During this process, the basic frame composed of support frame 1, welding block 6 and iron plate 5 ensures the overall rigidity and stability of the equipment. After lamination is completed, vacuum mechanism 3 stops working, lamination heating mechanism 4 stops heating, and then transmission mechanism 2 starts again to send the finished product out of the working area, completing the entire automated lamination cycle.
