Description

Technical Field

[0001] The utility model relates to the technical field of film material attachment and alignment, and more specifically, to a film material magnetic attraction alignment attachment structure. Background Art

[0002] In the touch and display industry, film attachment is a crucial process step, widely used in the production and manufacturing of various display screens. There are many types of such films, including PET (polyethylene terephthalate), TAC (cellulose triacetate), and SRF (a special functional film). Each has unique physical and chemical properties and plays a different role in the construction of the display screen. To meet the high-precision attachment requirements, CCD marking is often used in existing technologies for alignment. This method captures and analyzes image information on the film to determine its precise position, thereby achieving precise attachment.

[0003] However, CCD grabbing technology has exposed some problems in practical applications: because image information needs to be analyzed and processed, position calculation time is relatively long, which to some extent affects production efficiency. Secondly, CCD grabbing technology requires high consistency between the film material background and the shooting environment. When there are slight differences in the film material state, it can lead to inaccurate positioning and even trigger frequent alarms, causing unnecessary trouble in production. In addition to CCD grabbing, another common attachment method is snap-on attachment. This method uses a preset snap-on device to fix the position of the film material, thereby achieving attachment. However, the accuracy of snap-on attachment often fails to meet the requirements of high-precision attachment. Especially when processing films of special shapes or sizes, the design and manufacturing difficulty of the snap-on device are greatly increased. Therefore, we have improved this and proposed a magnetic suction alignment attachment structure for film materials. Utility Model Content

[0011] As an improved approach of the present invention, a plurality of alignment lines are connected end to end to form a pattern having the same shape as the main body of the film material.

[0012] As an improvement of the present invention, a detection component is provided on the film-sticking table, and the detection component is used to detect the alignment of the film material body.

[0013] As an improvement of the present invention, the detection member includes a plurality of sensors, and the plurality of sensors are embedded on the film-laminating platen.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this utility model belongs; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model. Reference to "embodiments" herein means that the specific features, structures or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the utility model. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] As described in the background technology, the existing technology often uses a CCD grabbing method for alignment. This method determines the precise position of the film material by capturing and analyzing the image information on the film material, thereby achieving precise attachment. However, CCD grabbing technology has exposed some problems in actual applications: since the image information needs to be analyzed and processed, the position calculation time is relatively long, which affects the production efficiency to a certain extent. Secondly, CCD grabbing technology has very high requirements for the consistency of the film material background and the shooting environment. When there are slight differences in the state of the film material, it may lead to inaccurate alignment and even trigger frequent alarms, bringing unnecessary troubles to production. In addition to the CCD grabbing method, another common attachment method is positioning attachment. This method uses a preset positioning device to fix the position of the film material to achieve attachment. However, the accuracy of positioning attachment is often difficult to meet the requirements of high-precision attachment. Especially when dealing with some film materials of special shapes or sizes, the design and manufacturing difficulty of the positioning device will be greatly increased.

[0025] In order to solve this technical problem, the utility model provides a film material magnetic alignment attachment structure.

[0026] Specifically, please refer to Figure 1 The membrane material magnetic alignment attachment structure specifically includes:

[0027] The film material body 1 and the film laminating plate 2 are provided. The film material body 1 is coated with magnetic powder 4. The film laminating plate 2 is embedded with a magnet bar 3. The magnet bar 3 and the magnetic powder 4 are adsorbed to achieve alignment of the film material body 1.

[0028] The utility model provides a magnetic alignment and attachment structure for film materials. This application achieves rapid and stable alignment of the film material body 1 by coating a magnet strip 3 on the surface of the film material body 1 and embedding a corresponding magnet strip 3 of the same size on the film attachment plate 2. The magnetic alignment method does not require a complex image analysis and processing process, which greatly shortens the position calculation time and thus improves production efficiency. The magnetic adsorption has strong stability and reliability, and can effectively reduce the influence of material edge differences on alignment accuracy, thereby ensuring attachment quality. Compared with CCD grabbing, the magnetic alignment method has lower requirements for environmental consistency, and can maintain a stable alignment effect even if there are slight differences in the film material state.

[0029] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0032] Example 1 of the magnetic attraction alignment attachment structure of the utility model

[0033] Please refer to Figure 1 The utility model discloses a magnetic alignment and attachment structure for film materials, comprising: a film material body 1 and a film sticking plate 2, wherein the film material body 1 is coated with magnetic powder 4, and the film sticking plate 2 is embedded with a magnet strip 3, and the magnet strip 3 is attracted to the magnetic powder 4 to realize the alignment of the film material body 1; the application realizes the rapid and stable alignment of the film material body 1 by coating the magnet strip 3 on the surface of the film material body 1 and embedding the corresponding magnet strip 3 of the same size on the film sticking plate 2, and utilizes the principle of magnetic adsorption; the magnetic alignment method does not require a complicated image analysis and processing process, greatly shortens the position calculation time, and thus improves production efficiency; magnetic adsorption has strong stability and reliability, and can effectively reduce the influence of material edge difference on alignment accuracy, thereby ensuring the attachment quality; compared with CCD grabbing, the magnetic alignment method has lower requirements on environmental consistency, and can maintain a stable alignment effect even if there are slight differences in the film material state;

[0034] In modern industrial production, time is cost. Complex image analysis and processing not only requires high-performance equipment support, but also consumes a lot of time. The magnetic alignment method directly utilizes magnetic force, eliminating multiple links such as image acquisition, analysis and calculation. It can complete the alignment of the membrane material body 1 in a very short time, speeding up the product flow on the production line and completing more attachment work per unit time, thereby greatly improving production efficiency, reducing production costs for enterprises and enhancing market competitiveness.

[0035] The side of the membrane body 1 away from the magnetic powder 4 is attached to the product, and the magnetic powder 4 can be dissolved or decomposed by a chemical solvent to achieve the purpose of cleaning. This method usually has a good cleaning effect and is not likely to leave scratches on the surface of the membrane body 1;

[0036] After the film material body 1 is used, it needs to be cleaned for reuse or subsequent processing. The method of using chemical solvents to dissolve or decompose the magnetic powder 4 can effectively remove the residual magnetic powder 4 on the surface of the film material body 1 and achieve thorough cleaning. Compared with some physical cleaning methods, chemical solvent cleaning will not cause mechanical damage to the surface of the film material body 1, such as scratches, wear, etc., thereby ensuring the integrity and surface smoothness of the film material. This is especially important for some film material application scenarios with high requirements on surface quality, such as optical films, electronic display screen films, etc., and can ensure that the film material can still maintain good performance and appearance after multiple uses.

[0037] Further, such as Figure 1-Figure 2 As shown, the number of magnetic powders 4 is the same as the number of magnet bars 3 , and the positions of the magnetic powders 4 correspond to the positions of the magnet bars 3 .

[0038] Further, such as Figure 3 As shown, a plurality of mounting holes 201 are provided on the film laminating plate 2 , and the mounting holes 201 are used for installing the film laminating plate 2 .

[0039] Furthermore, the corners of the film-applying table 2 are arc-shaped, which reduces the possibility of the film-applying table 2 scratching products or workers during use.

[0040] Example 2 of the utility model of the magnetic attraction alignment attachment structure of the membrane material

[0041] The utility model further improves the film material magnetic attraction and alignment attachment structure, such as Figure 3As shown, a number of alignment lines 6 are provided on the film laminating platen 2, and the alignment lines 6 are used to detect the alignment of the film material body 1 to ensure the quality of the alignment of the film material body 1; the alignment quality is visually detected. During the production process, the operator needs to quickly and accurately judge the alignment of the film material body 1. By setting the alignment lines 6 on the film laminating platen 2, an intuitive reference standard is provided for the operator. When the film material body 1 is placed on the film laminating platen 2, it is only necessary to observe the relative position relationship between the film material body 1 and the alignment lines 6 to immediately determine whether the alignment is accurate. This intuitive detection method does not require the aid of complex detection equipment, greatly improves the efficiency and convenience of detection, can timely discover alignment problems and make adjustments, ensures the alignment quality of each attachment operation, reduces the generation of waste due to inaccurate alignment, and improves the production qualification rate and economic benefits.

[0042] Further, such as Figure 3 As shown, several alignment lines 6 are connected end to end to form a pattern with the same appearance as the film material body 1. The alignment lines 6 are designed to be a pattern with the same appearance as the film material body 1, so that the alignment detection is more accurate. After the magnet strip 3 and the magnetic powder 4 are attached, by observing the positional relationship between the edges and corners of the film material body 1 and the alignment lines 6, it is possible to comprehensively and carefully judge whether the film material body 1 is offset and the degree and direction of the offset. This accurate judgment helps the operator to take targeted adjustment measures in a timely manner to ensure that the film material body 1 is accurately aligned, thereby improving the accuracy and quality of the attachment. The alignment lines 6 with matching appearance can more accurately reflect the actual alignment of the film material body 1, reduce the possibility of misjudgment, and further improve the controllability of the production process and the stability of product quality.

[0043] Example 3 of the utility model of the magnetic attraction alignment attachment structure of the membrane material

[0044] The utility model further improves the film material magnetic attraction and alignment attachment structure, such as Figure 3 As shown, a detection part is provided on the film-sticking table 2, and the detection part is used to detect the alignment of the film material body 1 to ensure the alignment quality of the film material body 1; in modern automated production, improving the degree of automation of detection is of great significance to improving production efficiency and quality stability. By setting up the detection part, the alignment of the film material body 1 can be automatically detected without frequent manual observation and judgment. The detection part can monitor the position status of the film material body 1 in real time. Once an abnormal alignment is found, it can send a signal in time to provide a basis for subsequent adjustment and processing. This automatic detection method not only improves the efficiency and accuracy of detection, but also reduces the negligence and errors that may be caused by manual detection, and ensures that the alignment quality of each product can be strictly monitored and guaranteed, further improving the automation level of the entire production process and the consistency of product quality.

[0045] Further, such as Figure 3 As shown, the detection part includes a plurality of sensors 5, which are embedded in the film laminating plate 2. After the magnet strip 3 and the magnetic powder 4 are attached, the sensors 5 are used for detection. If the sensors 5 detect the film material body 1, it means that the film material body 1 is deviated.

[0046] The sensor 5 has high-precision detection capabilities and can accurately sense the position information of the film material body 1. After the magnet strip 3 and the magnetic powder 4 are attached, the sensor 5 can monitor the deviation of the film material body 1 from the preset position in real time. If the sensor 5 detects the film material body 1, it means that the film material body 1 has deviated from the correct alignment position. This accurate judgment provides a reliable basis for timely adjustment of the alignment. Compared with traditional manual detection or rough detection methods, the sensor 5 detection can detect the deviation problem more quickly and accurately, avoiding subsequent attachment errors caused by failure to detect the deviation in time, and improving the accuracy of production and the reliability of product quality.

[0047] Further, such as Figure 3 As shown, the position of the sensor 5 corresponds to the side of the membrane material body 1; to ensure that no false alarm is triggered when the alignment is correct, the position of the sensor 5 corresponds to the side of the membrane material body 1. This is a carefully designed layout. When the membrane material body 1 is correctly aligned, the sensor 5 is outside the normal detection range and will not detect the existence of the membrane material body 1, thereby avoiding false detection and false alarm caused by the sensitivity of the sensor 5 itself or other factors. This design ensures the accuracy and reliability of the detection system. The alarm will only be triggered when a misalignment occurs, reducing unnecessary production interruptions and adjustments, improving production efficiency and stability, and at the same time, reducing the operating personnel's processing costs and psychological burden on false alarm information, so that they can focus more on other key links in the production process.

[0048] Furthermore, several sensors 5 are connected to a controller, and the controller is connected to an alarm. On the production line, timely discovery and handling of problems is the key to ensuring smooth production. When the sensor 5 detects that the membrane material body 1 is misaligned, the alarm is triggered by the controller to sound an alarm, which can immediately attract the attention of the staff. The staff can take corresponding measures in time, such as adjusting the position of the membrane material body 1, checking the operating status of the equipment, etc., to correct the misalignment problem and avoid further expansion of the problem, thereby ensuring the continuity of production and the stability of product quality. This timely reminder mechanism effectively reduces the generation of waste and production delays caused by the failure to timely discover and handle the misalignment problem, improves production efficiency and product quality, and also reduces production costs and production risks.
