Description

Technical Field

[0001] This invention belongs to the field of hot stamping technology for adhesive strips, and particularly relates to a hot stamping process for adhesive strips and a hot stamping apparatus thereof. Background Technology

[0002] Racquets are core equipment for ball sports such as badminton, tennis, and table tennis. To meet diverse needs such as anti-counterfeiting, nighttime visibility, aesthetic appeal, and brand recognition, most rackets currently integrate various marking structures on the outside of the frame's rubber strip. The industry standard design currently involves directly setting fluorescent strips, anti-counterfeiting marks, and decorative patterns on the outer surface of the racket's rubber strip. Fluorescent strips enable racket visibility and location in low-light or nighttime conditions, preventing equipment loss or damage from collisions; anti-counterfeiting marks distinguish genuine products from counterfeit ones, protecting brand and consumer rights; and aesthetically pleasing patterns enhance the overall visual appeal of the racket, enriching its appearance and meeting the aesthetic needs of different users.

[0003] However, the existing technical solutions have revealed obvious drawbacks in actual long-term use. During the process of hitting the ball, bumping, storing, and daily handling, the surface of the rubber strip will gradually wear down. Since the existing fluorescent strips, anti-counterfeiting marks, and aesthetic patterns are all directly attached to the outermost surface of the rubber strip, with the continuous wear of the rubber strip, these markings are very prone to problems such as wear and blurring, partial detachment, and complete peeling.

[0004] To address this, some improvements have attempted to add an additional protective layer. For example, patent CN204996086U discloses a fluorescent ping-pong paddle that glows in the dark, comprising a paddle blade and a handle connected to the blade. The paddle blade includes a base plate, sponge, and rubber. Its distinguishing feature is that a fluorescent edge strip is provided around the perimeter of the paddle blade, covering the sides of the base plate, sponge, and rubber; a fluorescent layer is provided on the smooth side of the rubber, and a protective film is placed outside this fluorescent layer. This invention, by adding the fluorescent edge strip and fluorescent layer, prevents the ping-pong paddle from becoming unusable due to wear and tear during use. Furthermore, the fluorescent layer makes the ping-pong paddle easily identifiable.

[0005] Through product use, it was found that adding a protective film can extend the lifespan of the markings to some extent. However, in practical applications, new technical problems arise. After long-term impacts, repeated friction, and daily use, the protective film may peel, crack, or detach. Dust and sweat can then seep into the gaps between the protective film and the adhesive strip, making it difficult to clean. Summary of the Invention

[0030] like Figure 1-5As shown, a hot stamping method for rubber strip 700 is disclosed, aiming to solve the technical defects caused by the external placement of markings on traditional racket rubber strip 700. Traditionally, fluorescent markings, anti-counterfeiting marks, decorative patterns, and other markings on the rubber strip 700 are directly attached to its outer surface. During long-term racket use, including hitting, gripping, and storage, these markings are easily worn, blurred, partially detached, or even completely peeled off. Even with a protective film, problems such as edge lifting, cracking, and delamination can occur. Dust and sweat can easily seep into the gaps between the film and the rubber strip 700, making cleaning difficult and severely affecting the integrity, aesthetics, and lifespan of the markings on the racket rubber strip 700. This method embeds the markings into the bottom of the rubber cavity 710 of the rubber strip 700 and then adheres it to the racket, achieving the purpose of displaying the markings and avoiding a series of problems such as easy wear and tear on external markings, contamination from the protective film, and edge lifting.

[0031] like Figure 2 and 3 As shown, during the hot stamping process of the adhesive strip 700, the first step is to clamp and position the adhesive strip 700. The transparent adhesive strip 700 is held with its opening facing upwards and inserted into the fixing groove 350 of the fixing base 300. The fixing groove 350 is hollow at both ends and positioned within the fixing base 300. Simultaneously, the two opening plates 330 on the fixing base 300 extend into the adhesive cavity 710 of the adhesive strip 700. This assembly method achieves initial positioning and fixation of the adhesive strip 700. Relying on the limiting constraint of the fixing groove 350, it effectively prevents the adhesive strip 700 from shifting or shaking during subsequent unfolding, hot stamping, and relocation processes. Furthermore, the design of the opening plates 330 extending into the adhesive cavity 710 in advance provides support for the uniform unfolding and shaping of the adhesive cavity 710.

[0032] like Figure 2 and 3 As shown, the fixed base 300 further includes a base plate 310 structure. First guide rails 320 are symmetrically mounted on both sides of the base plate 310. Two sliding plates are slidably mounted on the two sets of first guide rails 320 via sliders 384. The two sliding plates are fixedly connected to the two opening plates 330 one-to-one, thereby realizing the sliding adjustment function of the opening plates 330. A fixed plate 340 is fixedly mounted in the middle of the base plate 310. A through-cavity 341 is formed inside the fixed plate 340. The cross-section of the cavity 341 is square or rectangular. Parts of the structures of the two opening plates 330 are accommodated inside the cavity 341, and the outer wall of the opening plate 330 cooperates with the inner wall of the cavity 341 to form a fixing groove 350 for placing the adhesive strip 700. The split sliding structure design of the fixed base 300, relying on the guiding and limiting function of the first guide rail 320, can ensure the stability and coaxiality of the sliding process of the opening plate 330, and avoid uneven force on the expansion of the glue cavity 710 due to unilateral displacement.

[0033] Furthermore, such as Figure 2 and 3 As shown, each opening plate 330 consists of a horizontal plate 331 and a vertical plate 332. The horizontal plate 331 serves as a connecting and positioning structure, fixedly engaging with the sliding plate. The vertical plate 332 extends vertically and into the cavity 341 of the fixing plate 340, causing the fixing groove 350 to form a U-shaped cross-section structure. The transparent adhesive strip 700 is stably inserted into the U-shaped fixing groove 350, and the two vertical plates 332 precisely extend into the adhesive cavity 710 of the adhesive strip 700. The horizontal plate 331 and the vertical plate 332 can be integrally formed or separately fixedly connected. The integrally formed structure has high strength and is not easily deformed. At the same time, the U-shaped fixing groove 350 can fully wrap and limit the adhesive strip 700, preventing the adhesive strip 700 from locally lifting or misaligning, making the subsequent opening of the adhesive cavity 710 more uniform and regular.

[0034] like Figure 2-4 As shown, the opening plate 330 has two stable operating states to adapt to different processing procedures, such as... Figure 3 As shown, in the initial clamping state, the two opening plates 330 are in close contact with each other. At this time, a standard moving distance is reserved between the vertical plate 332 of the opening plate 330 and the inner wall of the cavity 341 of the fixed plate 340. This distance provides displacement space for the subsequent opening operation of the glue cavity 710; Figure 4 As shown, in the second state of expansion and forming, the two opening plates 330 separate outwards simultaneously, forming an opening groove 370 connecting the glue cavity 710 between them. The outer wall of the vertical plate 332 abuts against the inner wall of the cavity 341 of the fixed plate 340. The maximum opening amplitude of the opening plate 330 is precisely limited by the limiting effect of the cavity 341 wall, ensuring that the glue cavity 710 is expanded to a consistent degree during each processing. This effectively avoids problems such as hot stamping position deviation and incomplete hot stamping caused by expansion size deviation, ensuring the consistency of batch product processing.

[0035] like Figure 3 and 4 As shown, after the adhesive strip 700 is clamped and positioned, the two opening plates 330 are driven to expand outward simultaneously. With the support of the vertical plate 332, the adhesive cavity 710 of the adhesive strip 700 is evenly spread open, so that the upper surface of the fixing seat 300 forms an opening groove 370 that is completely connected to the adhesive cavity 710. The formation of the opening groove 370 can completely expose the bottom inner wall of the adhesive cavity 710, providing sufficient operating space for the subsequent placement, bonding and hot pressing of the hot stamping film 431, and avoiding the problem that the hot stamping operation space is limited and the hot stamping head 210 cannot penetrate deeply due to the opening of the adhesive strip 700 closing.

[0036] Furthermore, such as Figure 2As shown, the expansion and resetting actions of the opening plate 330 are completed by two sets of independent and synchronously linked first drive components 360. Each set of first drive components 360 includes a first motor 361, a gear 362, and a rack 363. The gear 362 is fixedly sleeved on the output shaft of the first motor 361, and the rack 363 is correspondingly fixedly assembled at the bottom position of the corresponding opening plate 330. The gear 362 and rack 363 mesh precisely for transmission. The meshing transmission method of gear 362 and rack 363 provides high transmission accuracy and fast response speed, enabling synchronous start and stop and equidistant expansion of the two opening plates 330, reducing displacement deviation. The first motor 361 can be a servo motor.

[0037] like Figure 1 , 3 As shown in Figure 4, after the glue cavity 710 is expanded and shaped, the fixing seat 300 supporting the glue strip 700 is moved to the working position directly below the hot stamping head 210. The pre-prepared hot stamping film 431 with the logo is placed inside the glue cavity 710 through the opening slot 370, so that the hot stamping film 431 is flat and adhered to the bottom wall of the glue cavity 710. Compared with the traditional external hot stamping method, this step places the logo hot stamping substrate at the bottom of the internal cavity 341 of the glue strip 700, realizing the embedded setting of the logo from a structural point of view. During the subsequent use of the racket, the outer substrate of the glue strip 700 can form a natural protection for the internal logo, isolating it from external friction, bumps, sweat and dust corrosion, and completely solving the core problem of easy wear and fall-off of traditional external logos.

[0038] After the hot stamping film 431 is positioned, the hot stamping head 210 at the top is driven to move vertically downward and penetrate into the adhesive cavity 710 of the adhesive strip 700 through the opening groove 370. The hot stamping film 431, which is attached to the bottom wall of the adhesive cavity 710, is subjected to constant temperature hot pressing treatment. The fluorescent markings, anti-counterfeiting patterns, decorative patterns and other markings on the hot stamping film 431 are accurately transferred to the bottom inner wall of the adhesive cavity 710 using the hot pressing transfer principle. The hot-pressing method of the hot-pressing head 210, which penetrates deep into the cavity 341, enables high-strength fusion and adhesion between the label and the inner wall of the adhesive cavity 710. The transfer adhesion is stronger, and it is less likely to cause local peeling or afterimage problems. Moreover, the embedded transfer-formed label is hidden inside the adhesive strip 700 and will not directly contact the external friction medium. There is no need to apply an additional protective film, which completely avoids the derivative problems of traditional protective films such as edge lifting, cracking, dust and sweat seepage, and difficulty in cleaning. This greatly extends the service life of the label, while ensuring that the outer surface of the adhesive strip 700 is smooth and intact, preserving the comfortable grip and overall aesthetics of the racket.

[0039] like Figure 1As shown, after the hot press transfer operation is completed, the hot stamping head 210 is first driven to vertically upward and reset, disengaging from the glue cavity 710. This prevents the residual heat of the hot stamping head 210 from continuously contacting the glue strip 700, which could cause deformation of the glue strip 700 or smudged markings, thus ensuring product molding quality. Then, the fixed seat 300 supporting the glue strip 700 is driven to move back to its initial feeding position, simultaneously controlling the two opening plates 330 to retract inward and reset, restoring the initial bonding state and releasing the stretching and shaping effect on the glue cavity 710 of the glue strip 700. Finally, the processed glue strip 700 is removed from the fixing groove 350, yielding the finished glue strip 700 with the embedded markings at the bottom of the glue cavity 710. This step-by-step reset process effectively avoids scratching and squeezing between the various structures and the finished glue strip 700 during the reset process, preventing damage to the newly formed markings and deformation of the glue strip 700, ensuring a high product qualification rate. Furthermore, after reset, the equipment can quickly enter the next processing cycle, adapting to the needs of mass production on an assembly line.

[0040] like Figure 1-5 As shown, this patent discloses a hot stamping device adapted to the hot stamping processing method of the adhesive strip 700 described above. The device includes a base 100 and a top plate 200, which are fixedly connected by multiple connecting columns 110. A fixing seat 300 for supporting the adhesive strip 700 is slidably mounted on the base 100. The fixing seat 300 is provided with a fixing groove 350 and a slidable and openable opening plate 330 structure, which can stably complete the clamping of the adhesive strip 700 and the opening and shaping of the adhesive cavity 710. The unwinding assembly 400 and the rewinding assembly 500 are respectively mounted on both sides of the base 100, which are used for automatic feeding of the hot stamping film roll 430 and waste film rewinding, respectively, replacing the traditional manual film laying and rewinding operation, realizing continuous feeding of the hot stamping film 431, and greatly improving the degree of automation and production efficiency. Two sets of pressing components 600 are symmetrically arranged on the base 100, which can vertically press down and limit the hot stamping film 431 that has been laid in place, completely eliminating the problems of loosening, displacement, and wrinkling of the hot stamping film 431, and ensuring that the hot stamping film 431 is tightly attached to the bottom wall of the adhesive cavity 710. The top plate 200 is equipped with a hot stamping head 210 that can be raised and lowered to complete the hot press transfer operation deep into the adhesive cavity 710. The entire device has a reasonable structural layout and strong linkage, and can automatically complete the entire process of positioning the adhesive strip 700, opening the adhesive cavity 710, laying the film, hot press transfer, and unloading the finished product, which greatly improves production efficiency.

[0041] like Figure 1As shown, the unwinding assembly 400 in the device specifically includes an unwinding roller 410 and multiple first guide rollers 420. The hot stamping film roll 430 is sleeved and assembled on the unwinding roller 410 and can automatically rotate and unwind as the operation progresses. The winding assembly 500 includes a winding roller 510 and a second guide roller 520. After being guided and limited by the multiple first guide rollers 420 and second guide rollers 520, the hot stamping film 431 is finally connected to the winding roller 510. The step-by-step guiding structure of multiple sets of guide rollers can accurately limit the conveying path of the hot stamping film 431, avoiding deviation, twisting, and stretching deformation during film conveying, ensuring uniform film conveying tension and flat laying. At the same time, the coordinated linkage between the unwinding roller 410 and the winding roller 510 can realize continuous, uniform, and stable conveying of the hot stamping film 431, eliminating the need for frequent manual material changes and film handling, effectively reducing manual intervention costs, and adapting to long-term continuous batch processing.

[0042] like Figure 1 and 5 As shown, two sets of pressing components 600 are symmetrically arranged on the left and right sides of the fixed base 300. Each pressing component 600 consists of a pressing cylinder 610 and a guide frame 620. The hot stamping film 431 is movably inserted inside the guide frame 620. The guide frame 620 can be vertically raised and lowered by the extension and retraction drive of the pressing cylinder 610. During operation, the guide frame 620 moves down to press down the hot stamping film 431, precisely limiting and fixing both ends of the film. The double-sided synchronous pressing structure design can tighten and flatten the hot stamping film 431 from both ends, completely eliminating the hidden dangers of film looseness, hollowness, and wrinkles. It ensures that the hot stamping film 431 is always flat and adheres to the bottom wall of the adhesive cavity 710, providing a guarantee for high-precision hot stamping transfer and avoiding defects such as incomplete, misaligned, and blurry markings caused by uneven film, thus greatly improving the finished product processing qualification rate.

[0043] like Figure 2 As shown, the fixed seat 300 achieves precise sliding displacement on the base 100 through the second drive assembly 380. The second drive assembly 380 includes a lead screw 381 and a second motor 382 that drives the lead screw 381. The second motor 382 can be a servo motor. Two sets of second guide rails 383 are mounted in parallel on the base 100. The bottom of the fixed seat 300 is connected to the lead screw 381 and the second guide rails 383 through multiple sliders 384. The drive structure using lead screw 381 transmission combined with double guide rail guidance provides high displacement accuracy and small positioning error, accurately conveying the fixed seat 300 to the hot stamping station and the reset station. At the same time, the self-locking performance of the lead screw 381 transmission ensures that the fixed seat 300 remains stationary during the hot stamping operation, preventing positional displacement caused by hot pressure vibration and ensuring the stability and accuracy of the hot stamping operation.

[0044] like Figure 1As shown, a third driving assembly (not shown) is also provided between the hot stamping head 210 and the top plate 200. The third driving assembly can drive the hot stamping head 210 to move horizontally. The structure of the third driving assembly can be similar to that of the second driving assembly 380, and is driven by a motor and a lead screw 381. The liftable hot stamping head 210 is specifically composed of a base 211, a telescopic cylinder 212, and a hot stamping pressure head 213. The two ends of the telescopic cylinder 212 are fixedly connected to the base 211 and the hot stamping pressure head 213, respectively. The hot stamping pressure head 213 has a heating assembly (not shown) integrated inside. By utilizing the telescopic stroke of the telescopic cylinder 212, the downward depth and reset height of the hot stamping head 213 can be precisely controlled, ensuring that the head can accurately penetrate into the adhesive cavity 710 and completely adhere to the film to complete the hot stamping. The hot stamping head 213 can be either square or roller-shaped. When used in a square configuration, it is lifted after hot stamping one area to hot stamp another. When used in a roller-shaped configuration, after hot stamping, the third drive component drives the hot stamping head 210 to move horizontally and roll. Both of these methods are within the scope of this invention. The heating component can achieve constant temperature control, ensuring stable and uniform hot stamping temperature, avoiding problems such as excessively high temperatures burning the adhesive strip 700 and the hot stamping film 431, and excessively low temperatures leading to insufficient adhesion of the label transfer, effectively improving the transfer quality and label adhesion stability.

[0045] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention and should not be construed as limiting the specific implementation of the invention to these descriptions. For those skilled in the art, the architectural form of this invention can be flexibly varied without departing from its conceptual framework, leading to the derivation of a series of products. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
