Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, and in particular to an automatic heat-sealing device for magnetically controlled soft covers and its process method. Background Technology

[0002] Among existing technologies, sun visors are becoming increasingly popular with consumers due to their advantages such as better applicability, driven by the electrification, intelligentization, and connectivity of new energy vehicles and the ever-evolving customer demands. Traditional sun visors have certain shortcomings in terms of function and practical application. For example, the vanity mirrors on sun visors are not large enough, and the lighting methods and scenarios are relatively limited, failing to adequately meet the needs of drivers and passengers.

[0003] To meet the aforementioned technical requirements, an innovative soft-cover makeup mirror sun visor has been designed and developed. During the manufacturing process of the mirror cover, the inner lining needs to be magnetically controlled. Therefore, the production process typically involves multiple steps, including material cutting, lamination, and heat sealing. However, existing magnetically controlled soft-cover production equipment often lacks flexibility; adjusting the production line for different specifications and designs requires significant time and resources. This limits production efficiency, increases production costs, and may lead to a decline in the product's market competitiveness. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a magnetically controlled soft-cover automatic heat-sealing device and its process method that significantly optimizes material handling and waiting time, and achieves seamless integration of production processes.

[0005] To achieve the above objectives, the present invention provides an automatic heat-sealing device for magnetically controlled soft caps, comprising: an inner liner body preparation device for automatically preparing an inner liner body with upper and lower transition layers; and a soft cap body forming device for hot-pressing the inner liner body with upper and lower fabrics to form a magnetically controlled soft cap body.

[0006] The inner liner body preparation device includes a rotating platform, a lower transition layer processing mechanism for cutting and supplying the lower transition layer raw material, an inner liner supply mechanism for supplying the inner liner substrate, an upper transition layer processing mechanism for cutting and supplying the upper transition layer raw material, and a liner forming mechanism for hot-pressing and bonding the lower transition layer raw material, the inner liner substrate, and the upper transition layer raw material to form the inner liner body.

[0007] The lower transition layer processing mechanism, the inner liner plate supply mechanism, the upper transition layer processing mechanism, and the liner plate forming mechanism are arranged in a ring around the circumference of the rotating platform. The rotating platform has a workstation corresponding to each mechanism. The surface of the workstation is provided with a positioning groove adapted to the inner liner plate substrate. The workstation is configured to sequentially circulate through the processing areas of the lower transition layer processing mechanism, the inner liner plate supply mechanism, the upper transition layer processing mechanism, and the liner plate forming mechanism under the drive of the rotating platform to prepare an inner liner plate body with upper and lower transition layers.

[0008] The soft cover body forming device includes a fabric processing mechanism, a hot-pressing and trimming mechanism, and a first transfer mechanism. The lining forming mechanism is connected to the hot-pressing and trimming mechanism through the first transfer mechanism. The first transfer mechanism is used to transfer the inner lining body formed by hot-pressing and bonding by the lining forming mechanism to the hot-pressing and trimming mechanism. The fabric processing mechanism is used to cut and shape the fabric raw material and supply it to the hot-pressing and trimming mechanism. The hot-pressing and trimming mechanism is used to hot-press and bond the fabric raw material with the inner lining body and trim the edges to form the magnetically controlled soft cover body.

[0009] To improve assembly accuracy, both the lower and upper transition layers are non-woven fabrics with adhesive backing, with the lower transition layer having a dark-colored non-woven fabric and the upper transition layer having a light-colored non-woven fabric. A soft-cover magnet is pre-attached to the inner lining substrate, with the dark-colored non-woven fabric of the lower transition layer corresponding to one polarity of the soft-cover magnet, and the light-colored non-woven fabric of the upper transition layer corresponding to the other polarity of the soft-cover magnet.

[0010] To ensure the continuity and stability of material supply, the lower transition layer processing mechanism includes a nonwoven fabric roll supply roller group, a material support platform, a laser cutting device, and a first suction cup assembly. The nonwoven fabric roll supply roller group continuously supplies adhesive-backed nonwoven fabric to the material support platform. The laser cutting device is fixedly mounted above the material support platform and configured to cut nonwoven fabric with the same shape as the inner lining plate under the drive of the X / Y axis drive mechanism. The first suction cup assembly is fixedly mounted on one side of the material support platform and configured to adsorb, position, and transfer the cut nonwoven fabric to the workstation located in the working area of ​​the lower transition layer processing mechanism under the drive of the X / Z axis drive mechanism. The structure of the upper transition layer processing mechanism is the same as that of the lower transition layer processing mechanism.

[0011] To achieve a simple and efficient supply of lining substrate, the lining substrate supply mechanism includes a material platform, a hopper, a pusher plate, and a second transfer mechanism. The hopper is located on the material platform for stacking several lining substrates, and the bottom of the hopper has a gap for the pusher plate to pass through. One end of the pusher plate extends into the gap, and the other end is configured to push the lining substrates in the hopper one by one to a predetermined position on the material platform under the drive of the X-axis drive mechanism. The second transfer mechanism is installed on one side of the material platform and is configured to transfer the lining substrates at the predetermined position to the workstation located within the working area of ​​the lining substrate supply mechanism under the drive of the X / Z-axis drive mechanism.

[0012] In order to ensure that the inner lining substrate can be accurately pushed to a predetermined position on the material platform, the free end of the push plate is provided with a hollow groove that matches the outer contour of the inner lining substrate, or the material platform is provided with a guide groove extending from the gap to the predetermined position.

[0013] To reduce the loss and deformation of the inner lining substrate during the transfer process, the second transfer mechanism includes a separation plate disposed on the power output end of the X / Z axis drive mechanism and a magnetically conductive block that is magnetically attracted to the soft cover magnet on the inner lining substrate. The separation plate is provided with a through hole for the magnetically conductive block to pass through. The magnetically conductive block is configured to move downward through the through hole and move to a predetermined position for adsorption under the drive of the X / Z axis drive mechanism. The structure of the first transfer mechanism is consistent with the structure of the second transfer mechanism.

[0014] To ensure the initial adhesion of the material, the liner forming mechanism includes a first frame and a first hot press upper die. A first cylinder is provided on the first frame. The first hot press upper die is installed at the power output end of the first cylinder and is configured to approach or move away from the work station located in the working area of ​​the lower liner forming mechanism under the drive of the first cylinder.

[0015] To further enhance the bonding strength between materials, a secondary hot pressing mechanism is provided between the liner forming mechanism and the lower transition layer processing mechanism. The secondary hot pressing mechanism includes a third transfer mechanism, a second frame, a second hot pressing upper mold, and a first hot pressing lower mold disposed opposite to the second hot pressing upper mold. A second cylinder is provided on the second frame, and the second hot pressing upper mold is installed at the power output end of the second cylinder and configured to approach or move away from the first hot pressing lower mold under the drive of the second cylinder. The first hot pressing lower mold is connected to the rotating platform through the third transfer mechanism, which is used to transfer the inner liner body pre-composite formed by the liner forming mechanism to the first hot pressing lower mold. The structure of the third transfer mechanism is consistent with the structure of the first transfer mechanism.

[0016] For a highly efficient fabric preparation process, the fabric handling mechanism includes a front fabric handling mechanism, a back fabric handling mechanism, a multi-axis robot, and a second suction cup assembly located at the free end of the multi-axis robot. The front fabric handling mechanism includes a fabric roll supply roller group, a cutting platform, a cutting blade, and a fabric clamp. The fabric roll supply roller group continuously supplies fabric raw material to the cutting platform. The fabric clamp is configured to flatten and fix the fabric raw material on the cutting platform under the drive of the X / Z axis drive mechanism. The cutting blade is located above the cutting platform and is configured to cut the fabric fixed by the fabric clamp under the drive of the Z axis drive mechanism. Raw materials; the structure of the back fabric processing mechanism is the same as that of the front fabric processing mechanism, and both are connected to the hot re-trimming mechanism through a multi-axis robot; the hot re-trimming mechanism includes a third frame, a hot-pressing punching upper die, and a second hot-pressing lower die arranged opposite to the hot-pressing punching upper die, and a third cylinder is provided on the third frame; the hot-pressing punching upper die is installed at the power output end of the third cylinder and is configured to approach or move away from the second hot-pressing lower die under the drive of the third cylinder; the surface of the second hot-pressing lower die is provided with a heat-sealing groove that matches the outline of the inner lining plate body, and the die surface of the hot-pressing punching upper die is provided with a cutting edge that matches the outline of the magnetic control soft cover body.

[0017] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is: to provide an automatic heat-sealing process for magnetically controlled soft caps, using the automatic heat-sealing device for magnetically controlled soft caps described in the above solution, and preparing the caps according to the following steps:

[0018] A) Preparation of the inner lining plate body, specifically including the following steps:

[0019] a) Start the rotating platform to drive the workstation to move in a circumferential direction;

[0020] b) The lower transition layer processing unit cuts the lower transition layer raw material and supplies the cut nonwoven fabric to the workstation.

[0021] c) The inner lining plate supply mechanism places the inner lining plate substrate into the positioning slot of the workstation;

[0022] d) The upper transition layer processing unit cuts the upper transition layer raw material and supplies the cut nonwoven fabric to the workstation.

[0023] e) Under hot pressing, the liner forming mechanism combines the lower transition layer, the inner liner substrate, and the upper transition layer to form the inner liner body;

[0024] B) Fabric processing and thermal bonding, specifically including the following steps: a) The first transfer mechanism transfers the prepared inner lining plate body from the rotating platform to the thermal bonding and edge cutting mechanism;

[0025] b) The fabric processing unit cuts the fabric raw material into the required shape and supplies it to the heat-re-trimming unit;

[0026] c) The hot-pressing and trimming mechanism combines the cut fabric material with the inner lining board body through hot pressing, and simultaneously completes the trimming of the fabric edges to form the final magnetic soft cover body.

[0027] The magnetic control soft cap automatic heat-sealing device and its process designed in this invention optimize material handling and waiting time through the use of a ring-shaped rotating platform and a multi-station structure, enabling seamless connection between various production stages and realizing a fully automated production process from raw material supply to finished product output. This effectively reduces production downtime and accelerates the production cycle. Simultaneously, precise laser cutting and an automated positioning system ensure accurate cutting and alignment of each piece of non-woven fabric and other materials, improving the consistency and appearance of the final product. Furthermore, the device features a specially designed double-layer hot-pressing process: the first hot-press is used for precise pre-pressing to ensure initial adhesion of the materials; the second hot-press is used to achieve a firm heat seal, guaranteeing the durability and functionality of the magnetic control soft cap. Moreover, the design of the device allows for rapid adaptation to the production of magnetic control soft caps of different specifications and design requirements through simple parameter adjustments and mold changes, greatly enhancing production flexibility and adaptability to market changes.

Detailed Implementation

[0043] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0044] Example 1.

[0045] like Figure 14As shown, in one embodiment of the present invention, the magnetically controlled soft cover is divided into an inner lining substrate 10, a soft cover magnet 20, a transition layer 30 composited on both sides of the inner lining substrate 10, and a fabric 40 integrally composited with the inner lining substrate 10 through the transition layer 30. The soft cover magnet 20 is pre-attached to the inner lining substrate 10 in several places, and the soft cover magnets 20 on the same surface of the inner lining substrate 10 have the same polarity.

[0046] like Figure 1-13 As shown, the magnetically controlled soft cover automatic heat sealing device described in this embodiment includes: an inner liner body preparation device 100, used to automatically prepare an inner liner body with upper and lower transition layers; and a soft cover body forming device 200, used to heat-press the inner liner body and upper and lower fabrics to form a magnetically controlled soft cover body.

[0047] The inner liner body preparation device 100 includes a rotating platform 1, a lower transition layer processing mechanism 2 for cutting and supplying the lower transition layer raw material, an inner liner supply mechanism 3 for supplying the inner liner substrate, an upper transition layer processing mechanism 4 for cutting and supplying the upper transition layer raw material, and a liner forming mechanism 5 for hot-pressing and bonding the lower transition layer raw material, the inner liner substrate, and the upper transition layer raw material to form the inner liner body.

[0048] The lower transition layer processing mechanism 2, the inner liner plate supply mechanism 3, the upper transition layer processing mechanism 4, and the liner plate forming mechanism 5 are arranged in a ring along the circumference of the rotating platform 1. The rotating platform 1 has a workstation 11 corresponding to each mechanism. The workstation 11 has a positioning groove 111 adapted to the inner liner plate substrate on its surface. The workstation 11 is configured to sequentially and cyclically pass through the processing areas of the lower transition layer processing mechanism 2, the inner liner plate supply mechanism 3, the upper transition layer processing mechanism 4, and the liner plate forming mechanism 5 under the drive of the rotating platform 1 to prepare an inner liner plate body with upper and lower transition layers.

[0049] The soft cover body forming device 200 includes a fabric processing mechanism 6, a hot-pressing and trimming mechanism 7, and a first transfer mechanism 8. The liner forming mechanism 5 is connected to the hot-pressing and trimming mechanism 7 through the first transfer mechanism 8. The first transfer mechanism 8 is used to transfer the inner liner body formed by hot-pressing and bonding by the liner forming mechanism 5 to the hot-pressing and trimming mechanism 7. The fabric processing mechanism 6 is used to cut and shape the fabric raw material and supply it to the hot-pressing and trimming mechanism 7. The hot-pressing and trimming mechanism 7 is used to hot-press and bond the fabric raw material with the inner liner body and trim the edges to form the magnetically controlled soft cover body.

[0050] In specific implementation, such as Figure 1 and Figure 2As shown, the rotating platform 1, as the driver of the entire preparation process, is driven by its circumferentially arranged workstations 11 to pass sequentially through the lower transition layer processing mechanism 2, the inner liner plate supply mechanism 3, the upper transition layer processing mechanism 4, and the liner plate forming mechanism 5. During this process, the lower transition layer processing mechanism 2 cuts the lower transition layer raw material into the required size and supplies it to the corresponding workstation 11. Subsequently, the inner liner plate supply mechanism 3 places the inner liner plate substrate in the positioning groove 111 on the workstation. Then, the upper transition layer processing mechanism 4 similarly cuts the upper transition layer raw material into the required size and supplies it to the corresponding workstation 11. Finally, under the action of the liner plate forming mechanism 5, the lower transition layer, the inner liner plate substrate, and the upper transition layer are combined under hot pressing to form a complete inner liner plate body.

[0051] like Figure 3 and Figure 9 As shown, after the liner forming mechanism 5 completes the preparation of the inner liner body, it is transferred to the hot lamination and trimming mechanism 7 through the first transfer mechanism 8. During this process, the fabric processing mechanism 6 cuts the fabric raw material to form a shape that matches the magnetic control soft cover design and supplies it to the hot lamination and trimming mechanism 7. The hot lamination and trimming mechanism 7 hot-presses the cut fabric raw material with the inner liner body and simultaneously completes the edge trimming process to form the final magnetic control soft cover body.

[0052] In this way, the workstation layout of the rotating platform 1 enables the lower transition layer processing mechanism 2, the inner liner plate supply mechanism 3, the upper transition layer processing mechanism 4, and the liner plate forming mechanism 5 to work synchronously and collaboratively, which greatly reduces manual operation links and shortens the production cycle. At the same time, the precise cutting and composite process reduces material waste, improves material utilization, and lowers production costs.

[0053] In some embodiments, to improve assembly accuracy, both the lower transition layer and the upper transition layer are non-woven fabrics with adhesive backing, and the non-woven fabric corresponding to the lower transition layer is dark-colored, while the non-woven fabric corresponding to the upper transition layer is light-colored; a soft cover magnet is pre-attached to the inner lining substrate, and the dark-colored non-woven fabric of the lower transition layer corresponds to one polarity of the soft cover magnet, while the light-colored non-woven fabric of the upper transition layer corresponds to the other polarity of the soft cover magnet.

[0054] In practice, the upper transition layer can use black non-woven fabric, and the lower transition layer can use white non-woven fabric. That is, the white non-woven fabric is pre-aligned with a certain magnetic pole (N / S) of the mirror cover magnet 20. When the inner lining substrate 10 and the transition layer 30 are hot-pressed together, the color of the non-woven fabric can be used to distinguish whether the magnetic pole direction of the mirror cover magnet 20 on the inner lining substrate 10 is incorrect (the N / S poles are marked on both sides of the magnet at the factory). This improves the accuracy of the production process. At the same time, the non-woven fabric with adhesive backing is heat-sealed to the inner lining substrate 10 through the adhesive side. During production, the orientation of the adhesive side of the non-woven fabric can be used as an auxiliary positioning method to prevent the upper and lower transition layers from being placed incorrectly and to ensure that the upper and lower transition layers can be firmly heat-sealed to the inner lining substrate 10. In addition, since the mirror cover magnet 20 is generally dark in color, using black non-woven fabric for the upper transition layer can also prevent the light-colored fabric of the mirror cover magnet 20 from showing the color of the magnet, thus maintaining the aesthetics and appearance consistency of the product. In addition, in this embodiment, since the inner lining substrate 10 is a smooth surface of resin composite glass fiber, the fabric 40 needs a high temperature to be firmly bonded to the inner lining substrate 10 through heat bonding. However, the high temperature will cause the fabric 40 to discolor. Therefore, the use of the transition layer 30 can avoid the problem of glue overflowing onto the surface of the fabric 40 and discoloration caused by excessively high heat bonding temperature. The product qualification rate is improved, the generation of waste products is reduced, the production cost is reduced, and the economic benefits are improved.

[0055] In some embodiments, such as Figure 2 and Figure 5 As shown, to ensure the continuity and stability of material supply, the lower transition layer processing mechanism 2 includes a nonwoven fabric roll supply roller group 21, a material support platform 22, a laser cutting device 23, and a first suction cup assembly 24. The nonwoven fabric roll supply roller group 21 continuously supplies adhesive-backed nonwoven fabric to the material support platform 22. The laser cutting device 23 is fixedly mounted above the material support platform 22 and is configured to cut nonwoven fabric with the same shape as the inner lining plate by laser under the drive of the X / Y axis drive mechanism (not shown in the figure). The first suction cup assembly 24 is fixedly mounted on one side of the material support platform 22 and is configured to adsorb, position, and transfer the cut nonwoven fabric to the workstation 11 located in the working area of ​​the lower transition layer processing mechanism 2 under the drive of the X / Z axis drive mechanism (not shown in the figure). The structure of the upper transition layer processing mechanism 4 is the same as that of the lower transition layer processing mechanism 2. In this embodiment, the nonwoven fabric roll is made by laminating a nonwoven fabric with a hot melt adhesive film, cutting the long roll into short rolls, and pre-treating it by baking at 80 degrees Celsius for 2 hours before punching and using it. This process removes moisture and stress from the nonwoven fabric, improves the dimensional and thermal stability of the material, and ensures that the material will not deform due to temperature changes during the subsequent hot pressing process.

[0056] In practice, the nonwoven fabric roll supply roller group 21 continuously supplies adhesive-backed nonwoven fabric from the nonwoven fabric roll to the material support platform 22. This step ensures the continuity of material supply and provides a stable material source for subsequent processing. Then, the laser cutting device 23, located above the material support platform 22, laser-cuts the nonwoven fabric according to the preset cutting pattern through the precise control of the X / Y axis drive mechanism, forming a nonwoven fabric sheet with the same shape as the inner lining plate. Then, the first suction cup assembly 24 is fixed to one side of the material support platform 22. Using the control of the X / Z axis drive mechanism, it adsorbs and positions the cut nonwoven fabric sheet, and then transfers it with the adhesive side facing up (the adhesive side is facing down when the upper transition layer processing mechanism 4 transfers the cut nonwoven fabric sheet) to the workstation 11 in the working area of ​​the lower transition layer processing mechanism 2, preparing for the next step of hot pressing lamination. In addition, the upper transition layer processing mechanism 4 adopts the same structural design as the lower transition layer processing mechanism 2. This symmetry not only improves the standardization of the equipment but also simplifies the maintenance and operation process.

[0057] In this way, the automated material supply, cutting and transfer process reduces direct human involvement, lowers operational complexity and workplace safety risks, and significantly improves production efficiency. At the same time, the laser cutting device 23 provides high-precision cutting capabilities, which reduces material waste, improves material utilization, and helps reduce raw material costs. Furthermore, since the upper and lower transition layer processing mechanisms have the same structure, maintenance and replacement of parts are simpler, which helps reduce potential equipment downtime and improves the stability of the production line.

[0058] In this embodiment, as Figure 6 As shown, the first suction cup assembly 24 consists of small suction cups 241 arranged on a plate surface. Additionally, in some possible embodiments, the X / Y axis drive mechanism has a programmable function according to the cutting contour to meet the production needs of magnetically controlled soft caps of different specifications.

[0059] In some embodiments, such as Figure 2 and Figure 7 As shown, in order to achieve simple and effective supply of inner lining substrate 10, the inner lining supply mechanism 3 includes a material platform 31, a material bin 32, a pusher plate 33, and a second transfer mechanism 34. The material bin 32 is provided on the material platform 31 for stacking several inner lining substrates, and the bottom of the material bin 32 is provided with a gap 35 for the pusher plate 33 to pass through. One end of the pusher plate 33 extends into the gap 35, and the other end is configured to push the inner lining substrates in the material bin 32 one by one to a predetermined position on the material platform 31 under the drive of the X-axis drive mechanism. The second transfer mechanism 34 is installed on one side of the material platform 31 and is configured to transfer the inner lining substrates at the predetermined position to the workstation 11 located in the working area of ​​the inner lining supply mechanism 3 under the drive of the X / Z axis drive mechanism.

[0060] In practice, the soft-cap magnet 20 is pre-attached and the inner lining substrate 10 is stacked in the hopper 32. The hopper 32 is located on the platform 31, providing a stable storage platform for the inner lining substrate. The design of the push plate 33 allows one end to extend into the gap 35 at the bottom of the hopper 32, and the other end, under the control of the X-axis drive mechanism, pushes the inner lining substrate from the hopper to the predetermined position on the platform 31 one by one. When the push plate 33 retracts and resets, the inner lining substrate 10 in the hopper 32 will automatically fall under its own weight. This process ensures the orderly supply of the inner lining substrate 10. The second transfer mechanism 34 is installed on one side of the platform 31 and is responsible for accurately transferring the inner lining substrate 10 located at the predetermined position to the workstation 11 under the drive of the X / Z axis drive mechanism, preparing for the subsequent hot pressing composite process.

[0061] Specifically, in the embodiments, such as Figure 7 As shown, the second transfer mechanism 34 includes a separation plate 341 disposed on the power output end of the X / Z axis drive mechanism and a magnetically conductive block 342 magnetically attracted to the soft cover magnet on the inner liner substrate. The separation plate 341 is provided with a through hole 343 for the magnetically conductive block 342 to pass through. The magnetically conductive block 342 is configured to move downward through the through hole 343 under the drive of the X / Z axis drive mechanism to a predetermined position for adsorption. The structure of the first transfer mechanism 8 is the same as the structure of the second transfer mechanism 34. Thus, after the inner liner substrate 10 is placed in the predetermined position on the material table 31, the magnetic block 342 of the second transfer mechanism 34 moves down through the through hole 343 on the separation plate 341 under the control of the X / Z axis drive mechanism, and moves to the predetermined position above the inner liner substrate 10. The magnetic block 342 uses its magnetism to attract the soft cover magnet 20 on the inner liner substrate 10, and firmly adsorbs the inner liner substrate 10. Then, the X / Z axis drive mechanism further drives the magnetic block 342 to transfer it together with the inner liner substrate to the workstation 11 of the next process. Then, the magnetic block 342 resets and retracts into the through hole 343, so that the inner liner substrate 10 is separated from the magnetic block 342 by the interference of the separation plate 341, and the transfer task is completed.

[0062] Additionally, in this embodiment, as Figure 2 and Figure 13 As shown, a magnetic pole sensor 36 is also provided at the bottom of the hopper 32. The position distribution of the magnetic pole sensor 36 is consistent with the position distribution of the soft cover magnet 20 placed on the inner liner substrate 10 in the hopper 32, so as to avoid incorrect placement of the inner liner substrate 10. As another design option, a magnetic pole sensor 36 can also be provided on the rotating platform 1 between the inner liner supply mechanism 3 and the upper transition layer processing mechanism 4. If the magnetic pole sensor 36 detects that the inner liner substrate 10 is placed in the wrong direction, the system will issue an alarm or automatically stop the rotation of the rotating platform 1 until the operator corrects the placement direction.

[0063] In some embodiments, such as Figure 7 and Figure 8 As shown, in order to ensure that the inner lining substrate 10 can be accurately pushed to a predetermined position on the material platform 11, the free end of the push plate 33 is provided with a hollow groove 331 that matches the outer contour of the inner lining substrate. Alternatively, the surface of the material platform 31 is provided with a guide groove extending from the gap 35 to the predetermined position. With this structural design, the hollow groove 331 allows the inner lining substrate 10 to be completely submerged in the hollow groove 331 when the push plate 33 pushes it, so that the second transfer mechanism 34 can transfer it to the workstation 11, ensuring stability and accuracy during the pushing process. Alternatively, the surface of the material platform 31 can also be provided with a guide groove extending from the gap 35 to the predetermined position. This guide groove provides a clear movement path for the inner lining substrate 10, allowing it to be accurately guided to the correct position along this path during the process of being pushed from the hopper 32 to the material platform 31, thereby ensuring the smooth progress of subsequent processes.

[0064] In some embodiments, such as Figure 2 and Figure 4 As shown, in order to ensure the initial adhesion of the material, the liner forming mechanism 5 includes a first frame 51 and a first hot press upper mold 52. A first cylinder 53 is provided on the first frame 51. The first hot press upper mold 52 is installed at the power output end of the first cylinder 53 and is configured to approach or move away from the work station 11 located in the working area of ​​the lower liner forming mechanism 5 under the drive of the first cylinder 53.

[0065] In specific implementation, the lower transition layer, the inner lining substrate 10, and the upper transition layer are sequentially stacked on the positioning groove 111 of the workstation 11 through the aforementioned process, and enter the working area of ​​the lining forming mechanism 5 under the drive of the rotating platform 1, ready for preliminary bonding. For example, the first hot pressing upper mold 52, driven by the power output end of the first cylinder 53, approaches and contacts the material on the workstation 11, applying pressure and heat to achieve preliminary bonding between the materials. In this embodiment, the hot pressing parameters of the lining forming mechanism 5 are configured as follows: temperature: 110-120℃, air pressure: 0.6-0.7MPa, hot pressing time: 3-5S. After the preset hot pressing time, the first cylinder 53 releases gas, reduces the thrust, and causes the first hot pressing upper mold 52 to leave the workstation 11, completing the preliminary bonding process.

[0066] In some embodiments, such as Figure 1 , Figure 2 and Figure 9As shown, in order to further enhance the bonding strength between materials, a secondary hot pressing mechanism 9 is provided between the liner forming mechanism 5 and the lower transition layer processing mechanism 2. The secondary hot pressing mechanism 9 includes a third transfer mechanism 91, a second frame 92, a second hot pressing upper mold 93, and a first hot pressing lower mold 94 disposed opposite to the second hot pressing upper mold 93. A second cylinder 95 is provided on the second frame 92. The second hot pressing upper mold 93 is installed at the power output end of the second cylinder 95 and is configured to approach or move away from the first hot pressing lower mold 94 under the drive of the second cylinder 95. The first hot pressing lower mold 94 is connected to the rotating platform 1 through the third transfer mechanism 91 for transferring the inner liner body pre-composite formed by the liner forming mechanism 5 to the first hot pressing lower mold 94. The structure of the third transfer mechanism 91 is consistent with the structure of the first transfer mechanism 8.

[0067] In specific implementation, the third transfer mechanism 91 has the same structure as the first transfer mechanism 8. That is, the third transfer mechanism 91 uses magnetic force to transfer the inner liner body, which is initially composited with the lower transition layer, the inner liner substrate 10, and the upper transition layer, from the rotating platform 1 to the first hot pressing lower mold 94. The second hot pressing upper mold 93 is installed at the power output end of the second cylinder 95. Driven by the second cylinder 95, the second hot pressing upper mold 93 descends and contacts the first hot pressing lower mold 94, applying greater pressure and heat to the inner liner body. In this embodiment, the hot pressing parameters of the secondary hot pressing mechanism 9 are configured as follows: temperature: 110-120℃, air pressure: 0.6-0.7MPa, hot pressing time: 6-10S. After the set hot pressing time, the second cylinder 95 releases gas, causing the second hot pressing upper mold 93 to rise, thereby completing the secondary hot pressing process. This step makes the structure of the inner liner body more stable, significantly reduces product quality problems caused by poor adhesion, and improves the performance and reliability of the final product.

[0068] Additionally, in this embodiment, as Figure 1 and Figure 2 As shown, an infrared material sensing sensor 60 is also provided between the secondary hot pressing mechanism 9 and the lower transition layer processing mechanism 2. The infrared material sensing sensor 60 is used to detect the workstation 11 that moves below it, to ensure that the prepared inner liner plate body 10 is sucked away by the third transfer mechanism 91 to prepare for the next preparation process cycle.

[0069] In some embodiments, such as Figure 6 and Figure 12As shown, for a highly efficient fabric preparation process, the fabric processing mechanism 6 includes a front fabric processing mechanism 61, a back fabric processing mechanism 62, a multi-axis robot 63, and a second suction cup assembly 64 disposed at the free end of the multi-axis robot 63. The front fabric processing mechanism 61 includes a fabric roll supply roller group 611, a cutting platform 612, a cutting blade 613, and a fabric clamp 614. The fabric roll supply roller group 611 is used to continuously supply fabric raw materials to the cutting platform 612. The fabric clamp 614 is configured to flatten and fix the fabric raw materials located on the cutting platform 612 under the drive of the X / Z axis drive mechanism. The cutting blade 613 is disposed above the cutting platform 612 and is configured to cut the fabric raw materials fixed by the fabric clamp 614 under the drive of the Z axis drive mechanism. The structure of the back fabric processing mechanism 62 is consistent with the structure of the front fabric processing mechanism 61, and both are connected to the heat-recovery trimming mechanism 7 through the multi-axis robot 63. In this embodiment, the fabric roll is made by laminating the fabric raw material with a hot melt adhesive film to reduce moisture and stress in the nonwoven fabric, thereby improving the dimensional and thermal stability of the material. This ensures that the material will not deform due to temperature changes during the subsequent hot pressing process, and also causes the fabric's raw edges to shrink, improving its appearance quality.

[0070] In practice, the fabric roll supply roller group 611 continuously supplies fabric raw materials from the fabric roll to the punching platform 612, ensuring stable fabric input. Under the control of the X / Z axis drive mechanism, the fabric clamp 614 flattens and fixes the fabric raw materials on the punching platform 612, preparing for punching. Then, the punching blade 613, driven by the Z axis drive mechanism, directly cuts the fabric raw materials fixed on the punching platform 612, completing the fabric punching work. The back fabric processing mechanism 62 has the same structure as the front fabric processing mechanism 61 and is used to perform the same punching process on the other side of the fabric to meet the needs of double-sided use. Finally, the multi-axis robot 63 and the second suction cup assembly 64 work together to automatically pick up and transfer the punched front and back fabrics from the punching platform 612 to the heat-recovery trimming mechanism 7, realizing seamless connection between fabric processing and subsequent processes. This compact mechanism design and automated process reduces the space occupied by the equipment, making the production line layout more compact and efficient. In this embodiment, the structure of the second suction cup assembly 64 is the same as that of the first suction cup assembly 24, and will not be described again here.

[0071] Additionally, in this embodiment, as Figure 12 As shown, a pressure block 615 is provided on the side of the punching platform 612 facing the fabric roll supply roller group 611. The pressure block 615 is connected to the punching platform 612 by a spring (not shown) to apply a clamping force to the fabric on the punching platform 612, so as to ensure that the clamping position of the fabric clamping device 614 can be reserved when the punching blade 613 cuts the fabric.

[0072] In some embodiments, such as Figure 10 and Figure 11 As shown, in order to improve the efficiency of the hot pressing and cutting process, the hot pressing and cutting mechanism 7 includes a third frame 71, a hot pressing and punching upper die 72, and a second hot pressing lower die 73 disposed opposite to the hot pressing and punching upper die 72. A third cylinder 74 is disposed on the third frame 71. The hot pressing and punching upper die 72 is mounted on the power output end of the third cylinder 74 and is configured to approach or move away from the second hot pressing lower die 73 under the drive of the third cylinder 74. The surface of the second hot pressing lower die 73 is provided with a heat sealing groove 75 that is consistent with the outer contour of the inner liner plate body. The die surface of the hot pressing and punching upper die 72 is provided with a cutting edge 76 that is consistent with the outer contour of the magnetic control soft cover body.

[0073] In practice, when the inner lining plate is placed on the second hot-pressing lower die 73, it is positioned by the heat-sealing groove 75. The hot-pressing punching upper die 72 is driven by the third cylinder 74 to descend and approach the second hot-pressing lower die 73. The hot-pressing action between the hot-pressing punching upper die 72 and the second hot-pressing lower die 73 causes the inner lining plate to be hot-pressed and bonded with the fabric material. At the same time, the cutting edge 76 precisely cuts the inner lining plate. In this embodiment, the equipment parameters of the hot-pressing edge trimming mechanism 7 are set as follows: temperature: 120-130℃, air pressure: 0.65-0.75MPa, hot-pressing time: 6-10S. After the hot-pressing and cutting are completed, the third cylinder 74 releases gas, and the hot-pressing punching upper die 72 rises and moves away from the second hot-pressing lower die 73, completing the hot-pressing edge trimming process. The automated design of this hot-pressing edge trimming mechanism 7 significantly improves the efficiency of the hot-pressing and cutting process, reduces manual intervention, and shortens the production cycle.

[0074] Additionally, in this embodiment, as Figure 9 As shown, a belt conveyor line 50 is also provided between the hot-pressing and trimming mechanism 7 and the secondary hot-pressing mechanism 9. The belt conveyor line 50 is connected to the first transfer mechanism 8 so that after the first transfer mechanism 8 transfers the inner liner plate body to the hot-pressing and trimming mechanism 7, it transfers the hot-pressed composite magnetic soft cover body to the belt conveyor line 50 during the resetting process. This reduces the downtime during the transfer process, speeds up the production cycle, and effectively utilizes the space of the production line, which helps to save space in the production area and makes the production line layout more reasonable.

[0075] The magnetic control soft cap automatic heat-sealing device designed in this invention optimizes material handling and waiting time through the use of a ring-shaped rotating platform and a multi-station structure, enabling seamless connection between various production stages and realizing a fully automated production process from raw material supply to finished product output. This effectively reduces production downtime and accelerates the production cycle. Simultaneously, precise laser cutting and an automated positioning system ensure accurate cutting and alignment of each piece of non-woven fabric and other materials, improving the consistency and appearance of the final product. Furthermore, the device features a specially designed double-layer hot-pressing process: the first hot press is used for precise pre-pressing to ensure initial adhesion of the materials; the second hot press achieves a firm heat seal, guaranteeing the durability and functionality of the magnetic control soft cap. Moreover, the design of this device allows for rapid adaptation to the production of magnetic control soft caps of different specifications and design requirements through simple parameter adjustments and mold changes, greatly enhancing production flexibility and adaptability to market changes.

[0076] To solve the above technical problems, such as Figure 1-13 As shown, this embodiment also provides a method for automatically heat-sealing a magnetically controlled soft cap, which uses the magnetically controlled soft cap automatic heat-sealing device described in the above scheme and is prepared according to the following steps:

[0085] c) The hot-pressing and trimming mechanism 7 heat-presses the cut fabric material with the inner lining board body and simultaneously trims the edges of the fabric to form the final magnetic soft cover body.
