Description

Technical Field

[0001] This utility model relates to the field of card production technology, specifically a laminating device for paper printed cards. Background Technology

[0002] As described in the published patent CN209454166U, "A Paper Product Card Surface Coating Device", paper product cards have a wide range of applications, such as business cards, hang tags, or playing cards. Cards are usually cut from a whole piece of paper to the required size. Since paper product cards are not waterproof and wear-resistant, they often need to be covered with a thin film before being cut into cards to enhance their waterproof and wear-resistant properties.

[0003] In summary, in the existing paper card production process, a transparent plastic film or metal perforated film needs to be coated on the surface of the card to improve its abrasion resistance and waterproof performance, and extend its service life. However, in the existing coating process, due to insufficient positioning accuracy of the film or card, and the possibility of slight displacement deviation during the conveying process, the relative positioning between the film and the card may be misaligned, resulting in an unsatisfactory coating effect.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 A laminating device for paper printed cards includes a base 101, on which a film feeding assembly 102 for feeding film, a card feeding assembly 103 for feeding cards, and a positioning assembly 104 for positioning the film and cards relative to each other are provided.

[0028] The diaphragm supply assembly 102 includes a diaphragm feeding assembly 105 for feeding diaphragms and a diaphragm feeding assembly 106 for feeding diaphragms at fixed points.

[0029] The card supply component 103 includes a card feeding component 107 for feeding cards and a card feeding component 108 for feeding cards at fixed points.

[0030] The positioning component 104 is disposed between the film feeding component 106 and the card feeding component 108 for positioning the card and attaching the film.

[0031] This utility model's laminating device solves the problem of poor adhesion between the film and the card in the prior art due to insufficient positioning accuracy and displacement deviation during the conveying process by setting up an independent and cooperative film supply component 102 (including a film feeding component 105 for stable film supply and a film fixed-point feeding component for precise and step-by-step film displacement) and a card supply component 103 (including a card feeding component 107 for orderly card supply and a card fixed-point feeding component for precise and step-by-step card displacement). A dedicated positioning component 104 is set at the key intersection of the two conveying paths.

[0032] Driven by their respective fixed-point feeding components, the film and the card can be precisely and stepwise transported to the predetermined workstation. Then, the positioning component 104 performs final, high-precision relative position calibration and fixation to ensure that the two achieve the required alignment accuracy during bonding. This collaborative mechanism of dual independent fixed-point conveying plus precise end-point positioning greatly suppresses the cumulative error and random offset during the conveying process, significantly reducing defects such as misalignment and curling caused by film or card position deviations. This directly and significantly improves the flatness, bonding firmness, and appearance quality of the card lamination. Thanks to the reliable improvement in lamination quality, the device effectively ensures the excellent abrasion resistance, waterproof performance, and service life of the laminated cards, while improving production yield, reducing scrap loss, and ensuring the continuous, efficient, stable, and reliable lamination process.

[0033] This novel laminating device, by setting up a film supply component 102 (including film feeding and fixed-point feeding) and a card supply component 103 (including card feeding and fixed-point feeding), combined with a positioning component 104 located between the two, achieves precise relative positioning and bonding of the film and the card. This effectively solves the problem of poor laminating effect caused by insufficient positioning accuracy or transmission displacement deviation in the prior art, significantly improves the card's abrasion resistance, water resistance, and service life, and ensures that the laminating process is efficient and reliable.

[0034] In this embodiment of the utility model, the positioning component 104 includes a positioning slide rail 109 fixed on the base 101, a positioning adjustment screw 110 rotatably mounted on the base 101, and a positioning adjustment motor 111 fixed on the base 101. A positioning plate 112 is slidably mounted on the positioning slide rail 109. A positioning frame 113 is snapped onto and limited on the positioning plate 112. The positioning plate 112 is screwed to the positioning adjustment screw 110. The positioning adjustment motor 111 is used to drive the positioning adjustment screw 110 to rotate forward and backward.

[0035] The positioning component 104 of the laminating device of this utility model provides high-rigidity linear guidance through the positioning slide rail 109, and works in conjunction with the high-precision positioning adjustment screw 110 driven by the positioning adjustment motor 111 to achieve gapless, micron-level precise displacement of the positioning plate 112 and the positioning frame 113. This design reduces the backlash error and positioning drift problems caused by gear backlash or connecting rod hinges in traditional positioning mechanisms. At the same time, the detachable snap-fit ​​limiting structure of the positioning frame 113 not only ensures the rigid constraint of card positioning, but also facilitates quick replacement of positioning molds adapted to different card sizes. The electromechanical cooperative positioning system dynamically maintains high alignment accuracy between the film and the card during the laminating process, fundamentally eliminating misalignment caused by vibration or inertia, and significantly improving the laminating qualification rate.

[0036] In this embodiment of the utility model, a plurality of limiting blocks 114 are fixedly arranged in a rectangular shape on the positioning plate 112, and the positioning frame 113 is snapped and fixed between the plurality of limiting blocks 114. The positioning frame 113 has a positioning inclined surface 115 on its four sides.

[0037] This invention's coating device achieves rigid locking and fixing of the positioning frame 113 through multiple rectangularly arranged limiting blocks 114 on the positioning plate 112. Combined with the inclined guide surface design of the inner walls of the positioning frame 113, the card can automatically slide into the precise alignment area along the inclined surface when placed. This structure not only ensures the absolute stability of the positioning frame 113 during operation (eliminating the risk of vibration displacement), but also significantly reduces the operation accuracy requirements for manual or robotic card placement through the self-correcting inclined surface guidance mechanism, ensuring accurate card positioning. At the same time, the modular locking design allows the positioning frame 113 to be quickly replaced for different sized cards (different positioning frames 113 can be replaced by adjusting the position of the limiting blocks 114), greatly improving the flexibility and overall efficiency of the production line.

[0038] In this embodiment of the present invention, the diaphragm feeding assembly 105 includes a lifting adjustment module 116 fixed on the base 101. An extension plate 118 is fixed on the slider of the lifting adjustment module 116. A plurality of support columns 119 arranged in a rectangular row are fixed on the extension plate 118. The support columns 119 are used for lifting the card.

[0039] The coating device of this utility model drives the slider and the extension plate 118 to make precise vertical displacement through the lifting adjustment module 116. With the help of multiple support columns 119 arranged in a rectangular array, the card is uniformly supported all over the area. The group of support columns 119 can accurately match the force distribution of cards of different sizes, and completely eliminate the problems of card bending, stress damage or coating wrinkling caused by traditional single-point lifting.

[0040] The lifting adjustment module 116 allows the support height to be finely adjusted as needed, seamlessly adapting to various cards and composite film materials with different thicknesses;

[0041] During the lifting process, the card only contacts the top of the support column 119 to avoid edge indentations or contamination caused by the mechanical grippers and ensure that the covered area is intact and undamaged;

[0042] It should be noted that during the actual feeding process, multiple films are placed in the feeding frame to form a stack, and then the feeding frame is lifted by the support column 119.

[0043] In this embodiment of the present invention, the diaphragm feeding assembly 106 includes a diaphragm linear module 120 fixed on the base 101. The diaphragm linear module 120 is used to transfer the diaphragm on the support column 119 to the positioning frame 113. The diaphragm linear module 120 and the positioning slide rail 109 are perpendicularly matched in space. A diaphragm lifting module 121 is fixed on the slider of the diaphragm linear module 120. An installation frame 122 is fixed on the slider of the diaphragm lifting module 121. A plurality of pneumatic suction nozzles 123 are arranged in a rectangular array on the installation frame 122.

[0044] The spatial vertical arrangement of the membrane linear module 120 and the positioning slide rail 109 in the coating device of this utility model achieves precise decoupling between the membrane conveying path and the card positioning direction. Combined with the rectangular array of pneumatic suction nozzles 123, it generates adaptive negative pressure adsorption over the entire membrane area. The pneumatic suction nozzle array 123 intelligently distributes the adsorption force points according to the membrane size, and the uniform adsorption force over the entire area completely eliminates the membrane stretching deformation or local wrinkles caused by traditional grippers.

[0045] The linear module drive, combined with the vertical orthogonal path design, enables the diaphragm to reach the card with high positioning accuracy. The diaphragm lifting module 121Z precisely and slowly descends to gradually eliminate the gap between the diaphragm and the card, preventing the formation of air bubbles.

[0046] The nozzle array maintains an adjustable negative pressure during the conveying process, effectively suppressing diaphragm displacement caused by airflow disturbance, and especially ensuring the morphological stability of the ultra-thin film during high-speed conveying.

[0047] In this embodiment of the utility model, the card feeding component 107 includes a conveyor belt component 124 fixed on the base 101. The conveyor belt component 124 includes a left conveyor belt 125 and a right conveyor belt 126 respectively disposed on the left and right sides of the positioning plate 112.

[0048] The coating device of this utility model has independently driven conveyor belt assemblies 124 symmetrically arranged on the left and right sides of the positioning plate 112. The left conveyor belt 125 continuously transports the cards to be processed to the positioning area, while the right conveyor belt 126 simultaneously moves out the coated finished products, eliminating the idle waiting time of traditional single-channel equipment and improving cycle efficiency.

[0049] The dual-sided conveyor belts support asynchronous start-stop control. When the positioning component 104 is fine-tuned, the upstream card can be buffered at the end of the left conveyor belt 125 to ensure continuous operation of the production line without interruption.

[0050] The gap between the conveyor belt and the positioning plate 112 is precisely controlled within the tolerance range, which not only allows the card to slide into the positioning frame 113 without resistance, but also prevents the vibration of the conveyor belt from interfering with the positioning accuracy.

[0051] In this embodiment of the utility model, the card feeding assembly 108 includes a card linear module 127 fixed on the base 101. The card linear module 127 and the diaphragm linear module 120 are arranged parallel to each other in space. A positioning clamping rod 128 is fixed on the slider of the card linear module 127. A first clamping cylinder 129 and a second clamping cylinder 130 are fixed on the positioning clamping rod 128. The first clamping cylinder 129 and the second clamping cylinder 130 are respectively aligned and cooperated with the front and rear sides of the mounting frame 122.

[0052] In this invention's coating device, the card linear module 127 and the film linear module 120 are arranged in parallel space. Combined with the first and second clamping cylinders 130 symmetrically arranged on the positioning clamping rod 128, they achieve precise and coordinated clamping of the front and rear sides of the mounting frame 122. Under the drive of the linear module, the two cylinders apply axial balanced clamping force to the film and the mounting frame 122, completely eliminating the film deflection or torsion caused by single-point force application.

[0053] The card linear module 127 and the diaphragm linear module 120 adopt a coaxial servo drive system to reduce the timing error of diaphragm delivery and card positioning, and ensure absolute synchronization of the bonding action.

[0054] In this embodiment of the present invention, a diaphragm calibration assembly 131 is further provided on the base. The diaphragm calibration assembly 131 includes a diaphragm calibration guide rail 132 fixed on the base 101. The diaphragm calibration guide rail 132 is perpendicularly matched with the diaphragm linear module 120 in spatial position. A calibration sampling camera 133 is fixed on the slider of the diaphragm calibration guide rail 132.

[0055] This invention's laminating device establishes a high-precision coordinate reference through the spatial vertical arrangement of the diaphragm alignment guide rail 132 and the diaphragm linear module 120, and, in conjunction with the alignment sampling camera 133, performs real-time visual positioning and detection of the diaphragm during transport.

[0056] Before the membrane arrives at the positioning area, defects such as hole misalignment, edge defects, or foreign matter attachment can be identified in advance, thus intercepting defective products from entering the lamination station at the source.

[0057] Working Principle: This coating device first feeds cards to a predetermined position via the left conveyor belt 125. Then, the card linear module 127 drives the first clamping cylinder 129 and the second clamping cylinder 130 to clamp the cards (the cards are equipped with warped clamping pieces; that is, an upwardly curved positioning patch is attached to each side of the lower end face of the card, and the first clamping cylinder 129 and the second clamping cylinder 130 clamp these positioning patches, thereby achieving precise positioning and clamping of the cards. If the card position is too far off, it will not be clamped). The first clamping cylinder 129 and the second clamping cylinder 130 place the clamped card into the positioning frame 113. The positioning adjustment motor 111 drives the positioning adjustment screw 110 to adjust the displacement of the positioning plate 112. The positioning frame 113 carrying the cards is brought closer to the diaphragm linear module 120. After the multiple pneumatic nozzles 123 on the diaphragm linear module 120 pick up the diaphragm from the support column 119, the diaphragm is moved onto the positioning frame 113. Then, the diaphragm lifting module 121 places the diaphragm into the positioning frame 113 and achieves adhesion. Then, the positioning adjustment motor 111 drives the positioning adjustment screw 110 to adjust the displacement of the positioning plate 112, so that the positioning frame 113 carrying the coated cards moves closer to the card linear module 127. Then, the card linear module 127 drives the first clamping cylinder 129 and the second clamping cylinder 130 to put the positioning frame 113 carrying the coated cards into the right conveyor belt 126 for the next step of degassing (achieved through a negative pressure chamber) and curing.

[0058] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
