Description

Technical Field

[0001] This invention relates to the field of mattress processing, and in particular to a fully automatic cotton applicator. Background Technology

[0002] During the manufacturing process of spring mattresses, one or more layers of flexible fabric, such as foam, latex, wool felt, or cloth, are glued to the outer surface of the spring core to achieve comfort and moisture resistance. Because flexible fabrics are difficult to grip, most existing bonding equipment uses manual feeding. The bonding process suffers from problems such as inaccurate material positioning, wrinkle formation, and the need to trim excess material later. Some of these steps cannot be completed by automated equipment and require manual labor, resulting in low production efficiency.

[0003] In related technologies, flexible fabric is fixed above the structure to be coated with cotton using a roller. The structure is moved by a conveyor belt, and the flexible fabric is rotated by the roller. The roller and the conveyor belt work together to bond the flexible fabric to different positions on the structure. After the cotton is coated on a single end face, it is still necessary to manually flip it over and coat the other end face. The automation level is low. At the same time, the feeding of the flexible fabric requires manual operation, which further exacerbates the disadvantage of low automation level. Summary of the Invention

[0004] To solve at least one of the above-mentioned technical problems, the present invention provides a fully automatic cotton applicator, the technical solution of which is as follows:

[0005] This invention provides a fully automatic fabric bonding machine, comprising a flexible fabric flattening and bonding structure and an adhesive application mechanism. The flexible fabric flattening and bonding structure includes a sorting mechanism, a movable tray, and a bonding platform. The sorting mechanism is located above the flexible fabric flattening and bonding structure and is used to flatten and grip the flexible fabric. The movable tray can switch horizontally between a feeding position and a working position to transport the flexible fabric from the feeding position to the working position. The working position is located below the sorting mechanism. The bonding platform is located below the flexible fabric flattening and bonding structure and is used to place and transport the mattress core or other base material that needs to be bonded. The adhesive application mechanism is used to apply an adhesive layer to the mattress core and is located upstream or downstream of the flexible fabric flattening and bonding structure.

[0006] The embodiments of the present invention have at least the following beneficial effects: In the present invention, the clamp moves along the first track to above the material tray. Under the action of the first and second connecting rods, the clamp descends and clamps the flexible fabric. The clamp transfers the flexible fabric to the movable pallet. At the same time, the bed core passes through the gluing mechanism under the action of the first and second conveying platforms, and an adhesive layer is set on the top of the bed core. The movable pallet then further conveys the flexible fabric to the bottom of the finishing mechanism, and the bed core is also further conveyed to the bottom of the working position. The finishing mechanism descends to flatten the flexible fabric and grabs it, raising the height of the flexible fabric in the flattened state. The movable pallet returns to its initial position. The height of the bed core is raised, and the relative position of the bed core and the flexible fabric is adjusted. The finishing mechanism drives the flexible fabric to descend, and the flexible fabric is bonded to the bed core. The bonded bed core descends again and is conveyed between the first and second conveying platforms. The first and second conveying platforms clamp the bed core and rotate it, causing the bed core to flip over. The flipped bed core repeats the bonding process to form a finished product with flexible fabric bonded on both sides, reducing manual intervention, saving costs, and achieving a high degree of automation.

[0007] In some embodiments of the present invention, the finishing mechanism includes an outer frame, on which a plurality of finishing components are disposed, each finishing component being spaced apart around the center of the outer frame. Each finishing component includes a moving part and a gripping component, the gripping component being disposed on the moving part for gripping a portion of the material on the fabric and moving to spread the fabric out.

[0008] In some embodiments of the present invention, the flexible fabric flattening and bonding structure includes a first lifting mechanism connected to the finishing mechanism for adjusting the height of the finishing mechanism and making the finishing mechanism have a starting position, a gripping position and a bonding position in the vertical direction. At the gripping position, the finishing mechanism flattens and grips the fabric on the movable pallet. At the bonding position, the finishing mechanism bonds the fabric to the bed core or bottom material located on the bonding platform.

[0009] In some embodiments of the present invention, the flexible fabric flattening and bonding structure includes a rotating mechanism, which drives the finishing mechanism to rotate horizontally so that after the finishing mechanism grasps the fabric, it can rotate the fabric at a suitable angle and then adhere it to the bed core or the bottom material.

[0010] In some embodiments of the present invention, the flexible fabric flattening and bonding structure further includes a centering mechanism located above the bonding platform for positioning the bed core or bottom material.

[0011] In some embodiments of the present invention, the centering mechanism includes two first centering components and two second centering components, the first centering components and / or the second centering components being able to move closer to or further away from each other, the first centering components being perpendicular to the second centering components, and the two first centering components and the two second centering components forming a centering area.

[0012] In some embodiments of the present invention, a visual inspection device and a controller are provided above the movable tray. The visual inspection device and the controller are electrically connected to the finishing mechanism. The visual inspection device monitors the shape and position of the flexible fabric and sends a signal to the controller. The controller controls the movable tray and the finishing mechanism so that the position of the finishing mechanism corresponds to the position of the flexible fabric.

[0013] In some embodiments of the present invention, the bonding platform includes a first conveyor belt and a second lifting mechanism, the second lifting mechanism being used to drive the first conveyor belt to move up and down, so that the first conveyor belt has a receiving station and a bonding station; the gluing mechanism includes a second conveyor belt, the first conveyor belt is connected to the second conveyor belt at the receiving station, and the first conveyor belt completes the bonding of the bed core or bottom material to the soft fabric at the bonding station.

[0014] In some embodiments of the present invention, the movable tray is provided with a plurality of fixing structures, each of which is used to fix the flexible fabric to the movable tray.

[0015] In some embodiments of the present invention, the fully automatic cotton applicator further includes a flipping mechanism, which is arranged adjacent to the adhesive applicator and is used to press and flip the bed core or bottom material of the fabric to be applied.

[0016] In some embodiments of the present invention, the flipping mechanism includes a flipping main frame, a flipping sub-frame, a first conveying platform, and a second conveying platform. The first conveying platform and the second conveying platform are parallel to each other and are spaced apart on the flipping sub-frame, being close to or far from each other. The first conveying platform, the second conveying platform, and the flipping sub-frame together are located within the range of the flipping main frame, and the flipping sub-frame is rotatably connected to the flipping main frame.

[0017] In some embodiments of the present invention, the fully automatic cotton applicator further includes a material picking device, which includes a clamp, a third lifting mechanism, and a traversing mechanism. The clamp moves up and down under the drive of the third lifting mechanism, and the traversing mechanism drives the clamp and the third lifting mechanism to move horizontally, and switches the clamp between a material picking station and a material dispensing station. The clamp picks up the fabric at the material picking station, and the material dispensing station corresponds to the feeding position of the movable pallet. At the material dispensing station, the clamp places the fabric onto the movable pallet by lifting.

[0045] This section will combine Figures 1 to 16 Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0046] In the description of this invention, it should be understood that the terms "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Features defined with "first" and "second" are used to distinguish feature names and do not have special meanings. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] This invention provides a fully automatic cotton applicator, which includes a flexible fabric flattening and bonding structure 200 and an adhesive applicator.

[0049] like Figure 1 , Figure 2 , Figure 3 As shown, the fully automatic cotton applicator includes a material picking device 100, which includes a clamp 102, a third lifting mechanism, and a traversing mechanism. The clamp 102 moves up and down under the drive of the third lifting mechanism. Furthermore, the third lifting mechanism employs a linkage assembly 103. The clamp 102 picks up a single piece of flexible fabric from the material pile and places it on the flexible fabric flattening and bonding structure 200, thereby bonding the flexible fabric with the bed core. To facilitate the design of the clamp 102's movements and reduce manual intervention costs, the material picking frame 101 is positioned on the ground. The clamp 102 is connected to the material picking frame 101 via the linkage assembly 103. The linkage assembly 103 can move horizontally on the material picking frame 101 via the traversing mechanism, allowing the clamp 102 to switch between a material picking station and a material dispensing station. The material dispensing station corresponds to the feeding position of the movable pallet 300. Meanwhile, the flexible fabric can be fixed on the clamp 102, so that the flexible fabric will move along with the linkage assembly 103 as it moves.

[0050] Specifically, the linkage assembly 103 includes a first link and a second link, which are hinged together. The first link is hinged to the clamp 102, and the second link is connected to the material handling frame 101. It can be understood that the first and second links change the distance between the clamp 102 and the material handling frame 101 by rotation, i.e., changing the height of the clamp 102. When the clamp 102 is in a high position, the angle between the first and second links decreases by rotation; when the clamp 102 is in a low position, the angle between the first and second links increases by rotation.

[0051] The second connecting rod is hinged with a sliding part, and a first track 104 is provided on the material handling frame 101. The sliding part is slidably connected to the first track 104. When the sliding part moves, the horizontal position of the clamp 102 changes. The clamp 102 can accurately place the flexible fabric on the flexible fabric flattening and bonding structure 200 through multi-degree-of-freedom movement.

[0052] like Figure 7 , Figure 8 As shown, the flexible fabric flattening and bonding structure 200 includes a sorting mechanism, a movable tray 300, and a bonding platform 500. The sorting mechanism is located on top of the flexible fabric flattening and bonding structure 200 and is used to flatten and grip the flexible fabric. The movable tray 300 receives the flexible fabric fixed on the clamp 102, and the flexible fabric is further transferred to the sorting mechanism via the movable tray 300. To realize the transfer function of the movable tray 300, a rack 214 and a gear 215 are provided, with the gear 215 meshing with the rack 214. When the gear 215 rotates, the rack 214 converts the rotation of the gear 215 into the movement of the movable tray 300, which moves along the direction of the rack 214.

[0053] The initial position of the movable pallet 300 is the feeding position. The clamp 102 places the flexible fabric on the movable pallet 300. The extreme position of the movable pallet 300 is the working position. The working position is below the sorting mechanism. When the flexible fabric is in the working position, the sorting mechanism can flatten the flexible fabric and grasp the flexible fabric.

[0054] Specifically, the movable tray 300 is provided with several fixing structures for fixing the flexible fabric to the movable tray 300. Specifically, the fixing structures are in the form of spikes, which embed into the flexible fabric to prevent relative movement between the flexible fabric and the movable tray 300. Alternatively, the fixing structures can be configured as pressure plate structures or suction cup structures.

[0055] The bonding platform 500 is located below the flexible fabric flattening and bonding structure 200 and is used to place and transport the bed core or other base material that needs to be bonded with fabric.

[0056] like Figure 4 , Figure 5 , Figure 6 As shown, the flexible fabric flattening and bonding structure 200 also includes a bonding frame 201. A finishing mechanism is mounted on the bonding frame 201. Due to its physical properties, the flexible fabric is prone to wrinkles. Understandably, wrinkled flexible fabric adhering to the mattress core has a significant impact on product quality. When a user lies on the mattress, the wrinkled flexible fabric can cause a foreign body sensation in the torso. The finishing mechanism can flatten the wrinkles on the flexible fabric and, on the other hand, grasp the flexible fabric after it has been flattened, temporarily separating it from the mattress core. Once the mattress core's position is adjusted, the flexible fabric is then bonded, facilitating mutual positioning between the flexible fabric and the mattress core. This ensures the flexible fabric completely covers the end face of the mattress core, further improving product quality.

[0057] Furthermore, the finishing mechanism includes an outer frame 202 and an inner frame 203, with the inner frame 203 connected to the outer frame 202 to form a whole. Several finishing components 206 are mounted on the outer frame 202, and the finishing mechanism performs both flattening and gripping functions through these components. Understandably, because the flexible fabric covers a large area, a single finishing component 206 cannot complete the flattening and gripping work over a large area. Therefore, multiple finishing components 206 are spaced apart around the center of the outer frame 202. To ensure uniform force distribution on the flexible fabric, each finishing component 206 is symmetrically positioned at the edge of the flexible fabric.

[0058] The finishing component 206 includes a moving part and a gripping component. The gripping component is mounted on the moving part and can move horizontally on the finishing mechanism. The gripping component changes position with the moving part to adapt to flexible fabrics of different sizes, improving the versatility of the finishing mechanism. The gripping component is used to grip a portion of the material on the fabric and simultaneously spread the material out in a moving manner. The gripping component can be configured as a pin structure, a suction cup structure, or a robotic gripper, etc.

[0059] Furthermore, when the gripping component is configured as a pin structure, it includes several first pins 204 and several second pins 205. Based on the physical properties of the flexible fabric, the first pins 204 and second pins 205 can insert into the flexible fabric and even pass through it as they move towards it, thus temporarily fixing the flexible fabric to the gripping component and achieving the gripping function. Each contact point between each first pin 204 and each second pin 205 and the flexible fabric can apply a lifting force, thereby ensuring that the force points on the flexible fabric are distributed and avoiding damage to the fabric's structure.

[0060] Specifically, the first pins 204 are parallel to each other, and the second pins 205 are parallel to each other. At the same time, in order to further improve the gripping ability of the gripping component, the first pins 204 and the second pins 205 are at an angle and are staggered. When the flexible fabric is inserted into the first pins 204 and the second pins 205, the first pins 204 and the second pins 205 hold the flexible fabric in place to prevent it from falling off.

[0061] The inner frame 203 is designed to facilitate the movement of the entire finishing mechanism, allowing for changes in the height difference between the flexible fabric and the bed core, and enabling the finishing mechanism to rotate. The inner frame 203 is equipped with a first lifting mechanism and a rotating mechanism. The first lifting mechanism adjusts the height of the finishing mechanism, while the rotating mechanism, connected to the frame, drives the finishing mechanism to rotate horizontally relative to the bonding frame 201.

[0062] In some examples, the moving part includes a first lead screw 207 and a first nut structure 208. The first lead screw 207 and the first nut structure 208 are engaged. When the first lead screw 207 rotates, the first nut structure 208 can move along the direction of the first lead screw 207. The gripping component is disposed on the first nut structure 208. When the first nut structure 208 moves, the gripping component moves together, so that the gripping component is adjusted to the edge of the flexible fabric to adapt to the size of the flexible fabric.

[0063] In some examples, the gripping component also includes two pin cylinders, which are connected to each first pin 204 and each second pin 205 respectively. The two cylinders drive each first pin 204 and each second pin 205 to perform linear motion. During the motion, the first pin 204 and the second pin 205 move closer to each other or further away from each other, thereby inserting into or detaching from the flexible fabric.

[0064] In some examples, a pressure block 209 is provided on the moving part, and an anti-slip structure is provided on the surface of the pressure block 209. Specifically, the anti-slip structure is a plurality of parallel spikes 210. When the pressure block 209 abuts against the surface of the flexible fabric, the spikes 210 are embedded in the flexible fabric, increasing the contact area between the pressure block 209 and the flexible fabric and ensuring the stability of the position of the flexible fabric.

[0065] In some examples, the pressure block 209 is provided with a mounting plate 211 and a clamping plate 213. The clamping plate 213 is hinged to the pressure block 209. The clamping plate 213 includes a first straight portion and a second straight portion, and the first straight portion and the second straight portion are at an angle. The first straight portion is hinged to the pressure block 209, and the second straight portion extends from the first straight portion toward the pressure block 209. During the rotation of the clamping plate 213, the second straight portion can move closer to or further away from the pressure block 209. Specifically, the mounting plate 211 is provided with a telescopic rod 212. The first end of the telescopic rod 212 is hinged to the mounting plate 211, and the second end of the telescopic rod 212 is hinged to the clamping plate 213. Understandably, the length of the telescopic rod 212 can change. When the length of the telescopic rod 212 decreases, the second straight section of the driving clamp 213 gradually moves away from the pressure block 209 and also away from the flexible fabric. When the length of the telescopic rod 212 increases, the second straight section of the driving clamp 213 gradually moves closer to the pressure block 209 and also closer to the flexible fabric. At this time, the second straight section of the clamp 213 and the pressure block 209 clamp the edge of the flexible fabric and move away from the center of the fabric with the moving part to smooth out the wrinkles on the fabric.

[0066] In some examples, the first lifting mechanism includes a second lead screw 216 and a second nut structure 217. The second lead screw 216 is vertically arranged, and the second nut structure 217 meshes with the second lead screw 216. When the second lead screw 216 rotates, the second nut structure 217 moves along the direction of the second lead screw 216. Alternatively, the rotation of the second nut structure 217 drives the second lead screw 216 to move. The second nut structure 217 is mounted on the inner frame 203, and the second lead screw 216 is fixedly mounted on the outer frame 202. When the second nut structure 217 rotates, the outer frame 202 adjusts its height along with the second lead screw 216, thereby raising the height of the lifting mechanism.

[0067] In some examples, since the inner frame 203 has a certain width and length, multiple first lifting mechanisms are provided to ensure stable lifting at various positions of the inner frame 203. These first lifting mechanisms are distributed around the center of the inner frame 203 and connected by a synchronous belt 218. Furthermore, the synchronous belt 218 is positioned to bypass each second nut structure 217. When the synchronous belt 218 rotates, each second nut structure 217 rotates simultaneously with the same amplitude, ensuring that all parts of the inner frame 203 are lifted to the same height, keeping the lifting mechanism always in a horizontal state.

[0068] In some examples, the rotating assembly includes a motor 219 and a reducer 220. The output end of the motor 219 is connected to the input end of the reducer 220. The fixed part of the reducer 220 is connected to the bonding frame 201, and the rotating part of the reducer 220 is connected to the inner frame 203. When the motor 219 is working, the finishing mechanism rotates relative to the bonding frame 201, thereby adjusting the horizontal position of the flexible fabric.

[0069] In some examples, the flexible fabric flattening and bonding structure 200 also includes a centering mechanism 400, which is located below the finishing mechanism, i.e., at the working position, and above the bonding platform 500. Further, the centering mechanism 400 is mounted on the bonding frame 201 or on the bonding platform 500. The centering mechanism 400 includes a first centering component 401 and a second centering component 402, both of which are capable of horizontal movement. The first centering component 401 and the second centering component 402 gradually push the bed core to the center of the working position.

[0070] In some examples, two first centering components 401 and two second centering components 402 are provided. To adapt the first and second centering components 401 and 402 to the shape of the bed core, the first and second centering components 401 and 402 are perpendicular to each other, with a gap between the two first centering components 401 and a gap between the two second centering components 402, forming a rectangular centering region 403. Initially, the bed core is at the bottom of the centering region 403, and the area of ​​the centering region 403 is larger than the end face area of ​​the bed core. As the bed core gradually moves upward into the centering region 403, it may not be in the center of the working position. The first and second centering components 401 and 402 gradually move towards the center of the working position, contacting the edge of the bed core and pushing it during this process.

[0071] Specifically, to enable the first centering component 401 and the second centering component 402 to change their horizontal position, a synchronous belt 218 is provided. The first centering component 401 and the second centering component 402 are connected to the synchronous belt 218, and the movement of the synchronous belt 218 pulls the first centering component 401 and the second centering component 402 to move. Alternatively, a lead screw and nut or similar method can be used to drive the first centering component 401 and the second centering component 402 to move.

[0072] In some examples, the bonding platform 500 is used to place and transport the bed core or fabric. When the height of the bonding platform 500 changes, the height of the bed core changes accordingly. It can be understood that the bonding platform 500 is in the working position to ensure that the flexible fabric fits the bed core.

[0073] Furthermore, the bonding platform 500 includes a first conveyor belt 501 and a second lifting structure. The second lifting structure includes a first drive rod 502 and a second drive rod 503. The bed core is positioned on the first conveyor belt 501, and the first drive rod 502 and the second drive rod 503 drive the height of the first conveyor belt 501 to change. Specifically, the first drive rod 502 and the second drive rod 503 are arranged crosswise and are hinged. When the first drive rod 502 and the second drive rod 503 rotate relative to each other, the height of the first conveyor belt 501 changes. When the first drive rod 502 and the second drive rod 503 rotate relative to each other, the distance between the ends of the first drive rod 502 and the second drive rod 503 will change accordingly. The first end of the first drive rod 502 is hinged to the first conveyor belt 501, and the second end of the first drive rod 502 is movably connected to the bonding frame 201. The first end of the second drive rod 503 is hinged to the bonding frame 201, and the second end of the second drive rod 503 is movably connected to the first conveyor belt 501. Alternatively, the first conveyor belt 501 can also be driven by a synchronous belt 218 or a gear 215 and rack 214, etc.

[0074] In some examples, both the bonding frame 201 and the first conveyor belt 501 are provided with slide rails 504, the second end of the first drive rod 502 is slidably connected to the corresponding slide rail 504, and the second end of the second drive rod 503 is also slidably connected to the corresponding slide rail 504.

[0075] The gluing mechanism is used to apply an adhesive layer to the upper surface of the bed core. The adhesive layer is applied by spraying or applying glue to ensure a firm bond between the bed core and the flexible fabric. The gluing mechanism is located adjacent to the flexible fabric flattening and bonding structure 200, and includes a second conveyor belt. The first conveyor belt 501 connects to the second conveyor belt at the receiving station. The gluing mechanism is located upstream or downstream of the flexible fabric flattening and bonding structure 200; that is, when multiple layers of fabric need to be bonded to the upper and lower surfaces of the bed core, repeated gluing is required. Specifically, the gluing mechanism operates by spraying, brushing, or rolling glue.

[0076] like Figure 9As shown, the fully automatic applicator also includes a flipping mechanism 600, which is arranged adjacent to the gluing mechanism. The flipping mechanism 600 is used to press and flip the bed core or backing material of the applicator. The flipping mechanism 600 includes a flipping main frame 601, a first conveyor platform 602, and a second conveyor platform 603. The flipping main frame 601 can be set on the ground, and both the first conveyor platform 602 and the second conveyor platform 603 can rotate on the flipping mechanism 600. Furthermore, the first conveyor platform 602 and the second conveyor platform 603 are parallel and there is a certain distance between them. The bed core is located between the first conveyor platform 602 and the second conveyor platform 603. During the rotation of the first conveyor platform 602 and the second conveyor platform 603, the bed core can be guided into or out of the flipping mechanism 600. Since the gluing mechanism sets an adhesive layer on one side of the bed core, and both sides of the bed core need to be bonded with flexible fabric, in order to improve the level of automation and save labor costs, the first conveyor platform 602 and the second conveyor platform 603 can rotate relative to the flipping host frame 601. It can be understood that the bed core rotates together, thereby flipping the bed core.

[0077] In some examples, the flipping mechanism 600 also includes a flipping sub-frame 604, on which the first conveying platform 602 and the second conveying platform 603 are disposed. The first conveying platform 602, the second conveying platform 603, and the flipping sub-frame 604 form an integral part within the range of the flipping main frame 601. The flipping sub-frame 604 is rotatably connected to the flipping main frame 601 to facilitate the flipping of the bed core.

[0078] In some examples, the distance between the first conveyor platform 602 and the second conveyor platform 603 can be adjusted to accommodate the thickness of the bed core and prevent the bed core from falling off during the rotation of the flipping subframe 604.

[0079] Furthermore, both the first conveying platform 602 and the second conveying platform 603 are equipped with a third drive rod 605 and a fourth drive rod 606, which are arranged intersectingly and hinged together. Similar to the structure of the bonding platform 500, on the first conveying platform 602, the first end of the third drive rod 605 is hinged to the first conveying platform 602, and the second end of the third drive rod 605 is slidably connected to the tilting sub-frame 604; the first end of the fourth drive rod 606 is hinged to the tilting sub-frame 604, and the second end of the fourth drive rod 606 is slidably connected to the first conveying platform 602. Simultaneously, on the second conveying platform 603, the first end of the third drive rod 605 is hinged to the second conveying platform 603, and the second end of the third drive rod 605 is slidably connected to the tilting sub-frame 604; the first end of the fourth drive rod 606 is hinged to the tilting sub-frame 604, and the second end of the fourth drive rod 606 is slidably connected to the second conveying platform 603.

[0080] In some examples, the fully automatic applicator also includes a feeding mechanism 700, which conveys the stack of flexible fabric to the picking device 100 for clamping by the fixture 102. The feeding mechanism 700 includes two parallel second tracks 701 and a tray 702. The flexible fabric is placed on the tray 702, and the tray 702 moves on the second tracks 701 to transfer the flexible fabric. Meanwhile, the fixture 102 is equipped with several grippers that can hold the flexible fabric on the tray 702.

[0081] In some examples, a vision detection device 801 and a controller are installed above the movable pallet 300. The vision detection device 801 and the controller are electrically connected to the sorting mechanism. When the flexible fabric is transported to the working position, the vision detection device 801 can monitor the position and shape of the flexible fabric and generate a specific electrical signal based on the current position and shape of the flexible fabric, which is then sent to the controller. The controller then issues action commands to the movable pallet 300 and the sorting mechanism to adapt to the position of the flexible fabric and ensure that the sorting mechanism is accurately positioned.

[0082] When using, such as Figure 10 As shown, in step one, the clamp 102 picks up the flexible fabric from the tray 702 and places it on the movable pallet 300. The bed core is located between the first conveying platform 602 and the second conveying platform 603, and is conveyed to the flexible fabric flattening and bonding structure 200. During the conveying process, an adhesive layer is applied by the gluing mechanism. Figure 11 As shown, in step two, under the monitoring of the vision inspection device 801, the movable pallet 300 transports the flexible fabric to the working position, placing the flexible fabric above the bonding platform 500. Simultaneously, the bed core is transported to the bonding platform 500. Figure 12 As shown, in step three, the finishing mechanism descends, flattening the flexible fabric; as Figure 13 As shown, in step four, the sorting mechanism grasps the flexible fabric, and the movable pallet 300 returns to the loading position, providing sufficient space for the bed core to rise; as Figure 14 As shown, in step five, the bonding platform 500 rises, and under the push of the first centering component 401 and the second centering component 402, the bed core is centered. The finishing mechanism rotates at a certain angle so that the flexible fabric corresponds to the position of the bed core. Further, the finishing mechanism descends, and the flexible fabric is bonded to the bed core; as shown... Figure 15 As shown, in step six, the height of the sorting mechanism is raised, the height of the fitting platform 500 is lowered, and the bed core is reintroduced into the flipping mechanism 600; as Figure 16 As shown, in step seven, the first conveying platform 602 and the second conveying platform 603 clamp the bed core and flip the bed core. The flipped bed core repeats the above steps so that the flexible fabric is bonded to both ends of the bed core.
