Description

Technical Field

[0001] This utility model relates to the field of automatic laminating machines, specifically an automatic laminating machine for high-transparency tempered glass laminated sheets. Background Technology

[0002] Traditional laminating machines primarily remove dust from the workpiece surface using a suction dust removal mechanism. This technical solution solves the problems of paper shifting and large dust particles on the workpiece surface.

[0003] However, when it comes to the automated application of high-transmittance tempered glass protective films that require extremely high cleanliness, the key challenge faced by existing technologies is the secondary contamination and control of micro-dust. Static electricity residue and workpiece contamination: Tempered glass laminates are prone to generating static electricity during transport and positioning, attracting a large amount of fine dust. Traditional suction dust removal methods are insufficient to completely remove the dust attracted by static electricity. Therefore, it is necessary to introduce contact-type static eliminator brushes to completely neutralize static electricity and remove dust. The key issue is that after the static eliminator brush contacts the workpiece, a large amount of dust and lint adheres to its bristles. Traditional laminating machines, whether using fixed or linked brushes, lack effective control over this "source of contamination."

[0004] Current technologies generally lack mechanisms for the immediate and efficient cleaning of static electricity elimination tools themselves. This disregard for contamination of the core tool can render all previous dust removal efforts futile, severely limiting the yield rate of high-transmittance films.

[0005] Therefore, there is an urgent need in this field for a technology that can integrate static elimination with efficient, sealed bristle self-cleaning functionality. This integrated solution is a key technology for ensuring that secondary contamination pathways caused by micro-dust are completely eliminated in the production environment of high-transparency tempered glass laminates, fundamentally guaranteeing product bonding quality and high yield. Utility Model Content

[0006] The main purpose of this utility model is to provide an automatic laminating machine for high-transparency tempered glass films, which aims to solve the technical problem mentioned in the background art that cleaning brushes can easily become a source of pollution, leading to secondary pollution from micro-dust and thus affecting the product yield.

[0007] To achieve the above objectives, this utility model provides the following technical solution: An automatic laminating machine for high-transparency tempered glass films includes a working platform on which a laminating roller is rotatably mounted. The machine is characterized by a positioning device on the working platform, comprising a fixed frame and a driving block. The driving block is slidably mounted and has an extension on one side. A first centering block is hinged to the driving block, and this first centering block has a zigzag-shaped sliding groove. The fixed frame has a limiting protrusion that is movably positioned within the sliding groove.

[0008] A second centering block is hinged to the mounting frame, and the first and second centering blocks are positioned opposite each other. The film is placed between the first and second centering blocks for positioning. Crucially, a cleaning brush that acts on the film is also fixedly connected to the first centering block.

[0009] With the above design, when the drive block slides, the cooperation between the limiting protrusion and the zigzag sliding groove drives the first centering block to move towards the center of the film while simultaneously generating an additional cleaning action. Furthermore, by setting a dust-collecting component around the cleaning brush, this invention achieves real-time self-cleaning of the cleaning tool, thereby eliminating secondary pollution sources.

[0010] As a preferred embodiment of the present invention, the positioning device further includes a vacuuming component that acts on the cleaning brush, the vacuuming component including a plurality of vacuuming fans arranged in an array.

[0011] As a preferred embodiment of this utility model, a return spring is provided between the fixing frame and the second centering block to ensure that the second centering block can automatically return to its original position after positioning.

[0012] As a preferred embodiment of this utility model, the second centering block is provided with a first adjustment part and a second adjustment part. The first adjustment part is used to abut against the film to achieve precise positioning; the second adjustment part abuts against the extension of the driving block and receives the driving force from the driving block.

[0013] As a preferred embodiment of this utility model, a drive cylinder is fixed on the fixing frame, and the movable end of the drive cylinder (such as the piston rod) is fixedly connected to the drive block, providing a stable and reliable power source for the entire positioning and cleaning operation.

[0014] Compared with the prior art, the present invention has the following significant advantages: 1. Integrated design to prevent secondary pollution: The design highly integrates the positioning of the coating sheet, surface cleaning, and the self-cleaning function of the cleaning tool. Through the collaborative work of the innovative vacuuming component and the cleaning brush, the brush is self-cleaned in real time while cleaning the coating sheet, thus solving the problem of secondary pollution caused by dust on the brush at the source.

[0015] 2. Precise positioning and efficient movement: Through the ingenious combination of the drive block, the zigzag sliding groove and the limiting protrusion, the precise centering and positioning of the coated sheet is achieved, and the movement is stable and reliable.

[0016] 3. High degree of automation and improved production efficiency: The entire positioning, cleaning and self-cleaning process is driven by a drive cylinder, which can be seamlessly integrated into the automated production line, reducing manual intervention and significantly improving production efficiency and product consistency.

[0020] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0021] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1 like Figure 1-2As shown, the present invention provides an automatic laminating machine for high-transparency tempered glass laminated sheets, mainly comprising a working platform 1, on which a laminating roller 2 for performing laminating operations is provided. The core improvement of this invention lies in the innovative installation of a positioning device 3 on the working platform 1.

[0023] The positioning device 3 includes a fixed frame 31 fixed on the working platform 1. A drive block 32 can slide along the guide rail (not shown) of the fixed frame 31. In order to drive the drive block 32, a drive cylinder is fixedly mounted on the fixed frame 31, and the piston rod of the drive cylinder is fixedly connected to the drive block 32.

[0024] One side of the drive block 32 has an integrally formed or fixedly connected extension 321. A first centering block 33 is hinged to the main body of the drive block 32 via a pin. An L-shaped, zigzag sliding groove 331 is carefully formed on the first centering block 33. Correspondingly, a fixed limiting protrusion 311 is provided on the fixing frame 31, which is precisely located within the sliding groove 331. This design is key to achieving compound motion.

[0025] A second centering block 34 is also hinged to the mounting bracket 31 via another pin. The first centering block 33 and the second centering block 34 are arranged opposite each other, and the space between them is used to place and position the coating sheet 4 to be processed. In order to enable the second centering block 34 to automatically reset, a return spring 35 is connected between it and the mounting bracket 31.

[0026] The second centering block 34 is provided with two functional parts: a first adjustment part 341 that directly contacts the edge of the film sheet 4, and a second adjustment part 342 that abuts against the extension part 321 of the drive block 32.

[0027] Crucially, a cleaning brush 332 is fixedly installed on the side of the first central block 33 facing the film sheet 4. This cleaning brush 332 is preferably made of high-density, anti-static material.

[0028] To address the core issues mentioned in the background art, this embodiment also integrates a dust collection assembly 5 into the positioning device 3. The dust collection assembly 5 includes multiple small, high-efficiency dust collection fans 51, whose air intakes are directly facing the bristles of the cleaning brush 332.

[0029] The workflow of this utility model is as follows: Feeding and initial positioning: The coated sheet 4 is conveyed to a position approximately between the first centering block 33 and the second centering block 34.

[0030] Drive and workpiece cleaning: The drive cylinder is started, and its piston rod extends upward, pushing the drive block 32 to slide in the vertical direction.

[0031] As the drive block 32 slides, its extension 321 pushes the second centering block 34 to rotate, causing it to swing away from the film sheet 4.

[0032] Subsequently, the drive block 32 moves downward, and the second centering block 34 swings towards the film sheet 4 under the force of gravity and the elastic force of the return spring 35; the drive block 32 also drives the first centering block 33 to move. Under the guidance of the limiting protrusion 311 and the zigzag sliding groove 331, the first centering block 33 drives the cleaning brush 332 on it to sweep across the surface of the film sheet 4, cleaning the surface dust and collecting it on the brush bristles.

[0033] Finally, the first centering block 33 and the second centering block 34 clamp the film sheet 4 firmly from both sides, completing the precise centering positioning and cleaning the surface of the film sheet.

[0034] Lamination: With the laminating sheet 4 precisely positioned and cleaned, it enters the working area of ​​the laminating roller 2 under the drive of the conveyor belt to perform the lamination action.

[0035] Reset and self-cleaning of the brush: After the coating is completed, the system enters the reset and self-cleaning stage. The piston rod of the drive cylinder retracts, causing the drive block 32 to slide in the opposite direction.

[0036] As the drive block 32 moves backward, the first centering block 33, guided by the limiting protrusion 311 and the sliding groove 331, will quickly lift and retract, causing the cleaning brush 332 fixed on it to vibrate mechanically.

[0037] At the instant the vibration occurs, multiple vacuum fans 51 of the vacuum assembly 5 start simultaneously, generating a strong negative pressure airflow field, which powerfully sucks away all the dust and impurities that have loosened from the bristles due to the vibration, thus completing the self-cleaning of the cleaning brush.

[0038] At the same time, the second centering block 34 also returns to its initial position under the pulling force of the return spring 35.

[0039] This completes one work cycle. The positioning device is fully reset, and the cleaning brush 332 is now clean and ready to perform contamination-free cleaning and positioning of the next film sheet.

[0040] Through the above embodiments, this utility model successfully integrates the positioning of the coated sheet, surface cleaning, and the self-cleaning function of the cleaning tool into a continuous automated process, effectively solving the industry pain point of secondary pollution from micro-dust and providing a reliable technical guarantee for the production of high-quality, high-transparency tempered coated sheets.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
