Description

Technical Field

[0001] The present application relates to the field of automated processing, and in particular to an aluminum tube film laminating machine. Background Art

[0002] In current technical practice, especially in battery heat dissipation management systems, the film lamination process on the surface of heat dissipation components such as aluminum tubes faces many problems. These problems stem from the complexity of the film lamination process and the high requirements for precision.

[0003] In traditional methods, this process mostly relies on complicated and delicate manual operations. The specific process is as follows:

[0004] Overall heating treatment: The staff first needs to manually put the aluminum tube into the heating furnace for overall heating. This step requires strict temperature control, usually the temperature needs to reach about 160°C. Temperature control not only affects the quality of the film, but also involves the difficulty of subsequent operations.

[0005] Precise cutting and positioning: The heated aluminum tube is placed on a special jig. Then, the staff needs to cut the appropriate length of PET composite film from the roll film. This step requires extremely high precision because the length, width and thickness of the film (for example, 78mm wide x 0.07mm thick, cutting length 2450mm) must strictly meet the specification requirements.

[0006] Complex film laminating process: The staff then manually aligns one end of the film with the side of the aluminum tube, and uses rollers to gradually fit and compact it. This process involves multiple steps, such as repeated heating, turning the aluminum tube, precise lamination, and uniform compaction of the film. These steps are not only cumbersome and time-consuming, but also very easy to cause quality problems such as bubbles or wrinkles due to improper operation.

[0007] High requirements for operator skills: Considering the size of the heat sink (such as the aluminum tube length 3000mm x width 30mm x thickness 1.6mm) and the strict standards of film pasting (such as no bubbles, no wrinkles), these operations place high demands on the proficiency and skills of the staff.

[0008] Therefore, in view of these problems, it is of great significance to develop an aluminum tube film laminating machine that can realize automatic operation. Utility Model Content

[0009] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide an automatic aluminum tube film laminating machine that can automate the processes of heating aluminum tubes, feeding films, folding films, and laminating films.

[0011] In order to realize the controllable feeding and cutting of the film, the film feeding and cutting assembly includes a reel for storing the film roll, a film output wheel for driving the film output, a film feeding wheel group composed of a plurality of guide wheels opposite to the reel, and a film cutting mechanism installed between the film output wheel and the film feeding wheel group and used for realizing the film cutting; the film roll is sleeved on the reel and driven by the film output wheel to output and the film feeding wheel group, and the film of a preset length is cut by the film cutting mechanism;

[0012] Furthermore, a magnetic powder brake controlled by a controller is installed on the reel.

[0013] Furthermore, the film cutting mechanism has a power source and two blades driven by the power source to open and close, and the two blades cut the film when they are closed. The power source is controlled by a controller to achieve controllable film cutting.

[0014] Furthermore, the film feeding and cutting assembly also includes a sensor for sensing the film, and the sensor is connected to the controller to send sensing data to the controller.

[0015] Furthermore, the film feeding wheel group is composed of an upper guide wheel and a lower guide wheel which are arranged opposite to each other, and at least one guide wheel is used as a power wheel to drive the film to run in the guide wheel group.

[0016] Furthermore, the upper guide wheel or the lower guide wheel in the film feeding wheel assembly is a floating guide wheel structure.

[0017] In order to realize the feeding and heating of the aluminum tube, the aluminum tube feeding and heating assembly includes a feeding guide wheel group, a feeding mechanism, and a heating unit. The aluminum tube is guided into the feeding mechanism by the feeding guide wheel group, and then the feeding mechanism drives the aluminum strip to pass through the heating unit to realize the feeding and heating of the aluminum tube. The feeding guide wheel group cooperates with the aluminum tube feeding and heating assembly.

[0018] Furthermore, the heating unit is a high frequency welding machine having a heating channel for the aluminum tube to pass through and heat the aluminum tube.

[0019] Furthermore, the feeding mechanism can be controlled to move in the vertical direction, thereby adjusting and stabilizing the matching position of the aluminum tube and the heating unit.

[0020] Furthermore, the feeding mechanism is composed of two sets of relatively matched conveyor belts, and a clamping gap that matches the aluminum tube is formed between the two conveyor belts. The aluminum tube is clamped and driven to move through the clamping gap.

[0021] To achieve the laminating work, the film laminating assembly includes a film folding wheel group composed of multiple film folding wheels with different film folding angles, a hot air gun for heating the aluminum tube, a plasma cleaning machine for cleaning the surface of the aluminum tube and the film and removing static electricity, a pressing wheel and a pressing mechanism.

[0022] Furthermore, there are two groups of pressing mechanisms, which are used to press the aluminum tube coated with the film to improve the firmness of the combination between the film and the aluminum tube.

[0023] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0030] 6. Reduce material waste: Through precise film cutting mechanism and efficient heating unit, material waste is reduced and material utilization rate is improved.

[0044] Reference Figure 1-3 The present embodiment discloses an aluminum tube film laminating machine, comprising a film feeding and cutting component 1, an aluminum tube feeding and heating component 2, a film laminating component 3, and a controller (not shown in the figure) for controlling the operation of each component, wherein the film feeding and cutting component 1 and the aluminum tube feeding and heating component 2 respectively feed film and aluminum tube into the film laminating component 3, and laminat the film on the outer surface of the aluminum tube in the film laminating component 3.

[0045] Specifically, in the film feeding and cutting assembly 1, there is a reel 4, on which a film roll 5 is placed, and the reel 4 is used to store and release the film. The design of the reel 4 ensures that the film can be smoothly unrolled to prevent wrinkles or entanglements during the film feeding process. In order to more accurately control the tension and output speed of the film, a magnetic powder brake is installed on the reel 4 (installed on the back of the reel, not shown in the figure). This brake can adjust the braking force according to the instructions of the controller, thereby controlling the release speed and tension of the film.

[0046] In the film feeding and cutting assembly 1, there is a film output wheel 6 that cooperates with the reel 4. The film is guided from the reel 4 to the film output wheel 6. The main function of this output wheel is to pull the film out from the reel 4 at a constant speed and tension to ensure the flatness and tension consistency of the film.

[0047] In the film feeding and cutting assembly 1, there is a film feeding wheel group 7, and the film output wheel 6 feeds the film to the film feeding wheel group 7 composed of multiple guide wheels. These guide wheels accurately control the path and tension of the film to ensure the stability and flatness of the film during the entire feeding process. The guide wheels in the film feeding wheel group 7 are designed as upper guide wheels and lower guide wheels, and at least one guide wheel is used as a power wheel. These guide wheels ensure the smooth operation of the film during the feeding process. In addition, the upper guide wheel or the lower guide wheel adopts a floating structure, which can be automatically adjusted according to the tension and position of the film, thereby further improving the accuracy and reliability of film feeding.

[0048] In the film feeding and cutting assembly 1, there is a film cutting mechanism 8, which is located between the film feeding wheel group 7 and the film output wheel 6. The mechanism includes two blades, and the opening and closing actions of the two blades are driven by a power source. When the two blades are closed, the film can be accurately cut to ensure that the length of each cut meets the preset standard. The power of the entire film feeding and cutting assembly 8 comes from a special power source, which is controlled by a controller. The controller controls the power source according to preset parameters to ensure that the film feeding and cutting process meet the required accuracy and speed. In most cases, the power source is a motor controlled by the controller.

[0049] In this embodiment, in order to further improve the accuracy and reliability, a sensor is also included in the film feeding and cutting assembly 1. This sensor can detect whether there is a film at the location, such as after the film roll is used up, through the controller to prevent erroneous operation.

[0050] In this embodiment, the aluminum tube feeding and heating assembly 2 is an important component of the automatic aluminum tube film laminating machine, and its design and function ensure that the aluminum tube can be accurately conveyed and heated for the subsequent film laminating process.

[0051] Specifically, the aluminum tube feeding and heating assembly 2 includes a feed guide wheel group 9, a feeding mechanism 10 and a heating unit 11. The aluminum tube first enters the machine through the feed guide wheel group 9. The main function of this guide wheel group is to ensure that the aluminum tube can smoothly and correctly enter the next step of the feeding mechanism 10. The design of the feed guide wheel group takes into account the size and shape of the aluminum tube to ensure that the aluminum tube will not be twisted or damaged during the transportation process.

[0052] Following the feed guide wheel group 9 is the feeding mechanism 10, which is responsible for guiding the aluminum tube from the feed guide wheel group 9 and smoothly conveying it to the heating unit 11. The mechanism is usually composed of two sets of relatively matched conveying belts, which clamp the aluminum tube on the upper and lower sides and provide sufficient force to push the aluminum tube forward. This design allows the aluminum tube to be in a stable position during the conveying process and avoids deviation or rotation. In order to accommodate aluminum tubes of different sizes and shapes, the feeding mechanism 10 is designed to be movable in the vertical direction. This adjustability allows the machine operator or the control system to adjust the position of the feeding mechanism 10 according to the specific size or position change of the aluminum tube, ensuring that the aluminum tube can smoothly pass through the heating unit while maintaining a stable position relationship between the aluminum tube and the heating element 11.

[0053] It should be understood that in the feeding mechanism 10, a clamping gap is formed between the two conveyor belts to match the aluminum tube. This gap can be appropriately adjusted according to the diameter of the aluminum tube to ensure that the aluminum tube is firmly clamped. In this way, the feeding mechanism 10 can effectively control the conveying of the aluminum tube while avoiding deformation or damage to the aluminum tube.

[0054] In this embodiment, after passing through the feeding mechanism 10, the aluminum tube will be introduced into the heating unit 11. This unit is usually designed with a high-frequency welding machine, which is provided with a heating channel for the aluminum tube to pass through. This heating channel can heat the aluminum tube evenly and quickly to reach the temperature required for film lamination. The use of the high-frequency welding machine ensures high efficiency and consistency of the heating process.

[0055] It is understandable that the design of the aluminum tube feeding and heating assembly 2 takes into account accurate conveying control, efficient heating treatment, and adaptability to aluminum tubes of different sizes. These features ensure that the aluminum tube can reach a good state during the entire preparation stage before film pasting, and better ensure the quality and consistency of film pasting.

[0056] In this embodiment, the film-applying assembly 3 includes a film-folding wheel set 12, which is composed of a plurality of film-folding wheels with different film-folding angles. These film-folding wheels are carefully designed to adapt to the physical properties of the film and the required bonding curvature. By adjusting the angle of the film-folding wheel, the film can be closely attached to the surface and contour of the aluminum tube without generating bubbles and wrinkles.

[0057] In this embodiment, the film laminating assembly 2 further includes a pressing wheel 13. After the film is laminarized on the aluminum tube by the film folding wheel assembly, the pressing wheel 13 is used to apply pressure to the aluminum tube covered with the film. This process not only completes one of the film laminating actions, but also helps to ensure that there is no air gap between the film and the aluminum tube, and further eliminates any bubbles or wrinkles that may exist.

[0058] In this embodiment, the film laminating assembly 2 further includes a plasma cleaning machine 14 and a hot air gun 15, wherein, before laminating by the pressing wheel 13, in order to ensure the cleanliness of the aluminum tube surface and the adhesion of the film, the plasma cleaning machine is used to clean and pre-treat the aluminum tube and the film surface. Plasma cleaning can effectively remove surface pollutants, grease and static electricity, thereby improving the bonding quality of the film.

[0059] In this embodiment, the heat gun 15 is used to locally heat the aluminum tube during the film application process, which helps soften the film so that it can be more easily applied and shaped to the surface of the aluminum tube. The heating also helps activate the adhesive on the back of the film to ensure a strong bond between the film and the aluminum tube.

[0060] Finally, the film laminating assembly 2 includes a special pressing mechanism 16, which has two groups and is dedicated to applying additional pressure to the aluminum tube and the film in the final stage of the film laminating process. Its structure and function are consistent with the pressing wheel 13. This step not only ensures the close contact between the film and the aluminum tube, but also improves the bonding firmness of the film, ensuring stability and durability in long-term use.

[0061] Through the coordinated work of the above-mentioned components, the film laminating component 2 of the automatic aluminum tube film laminating machine can achieve high-efficiency and high-quality film laminating work, ensuring that the film coverage on the surface of the aluminum tube is uniform, smooth and flawless, meeting the strict requirements on film laminating quality in applications such as battery heat sinks.

[0062] As a further description of the present embodiment, more specifically, in the present embodiment, there are 9 groups of film removing wheels, and each group of film folding wheels consists of two symmetrically arranged film folding wheels. When the film passes through the first group of film folding wheels, the first group of film folding wheels folds the unattached films on both sides to 150°, the left wheel in the second group of film folding wheels is adjusted to 110°, and the right wheel is adjusted to 130°, the left side of the third group of film folding wheels is -70°, and the right side is -110°, and the left film is folded inward, the left side of the fourth group of film folding wheels is -30°, and the right side is -110°, and the left side of the film is folded inward, the left side of the fifth group of film folding wheels is -10°, and the right side is -90°. At this time, the left side of the film is close to the upper surface of the aluminum tube, and the film passes through the pressing wheel 13 to pre-press the left side of the film onto the aluminum tube. The hot air gun 15 continues to heat the aluminum tube during the feeding process, and the first layer of pressing wheels presses the left side of the film to complete the first layer of pressing process. After the first layer of film is pressed, the aluminum tube and the film pass through a plasma cleaning machine 14 to remove surface static electricity, activate the film surface, and increase adhesion performance. The sixth set of film folding wheels has a left angle of -10° and a right angle of -90°. The seventh set of film folding wheels has a left angle of -10° and a right angle of -70°. The eighth set of film folding wheels has a left angle of -10° and a right angle of -50°. The ninth set of film folding wheels has a left angle of -10° and a right angle of -30°. The ninth set of film folding wheels has a left angle of -10° and a right angle of -10°. The right film is pressed against the aluminum tube and overlapped with the first layer of film. The first set of pressing mechanisms 16 presses the right film to complete the second layer pressing process. Finally, the second set of pressing mechanisms 16 modules press the entire film to complete the film folding and film pasting processes. After the material is discharged, it is manually sorted into boxes.

Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims.
