Description

Technical Field

[0001] This invention relates to the field of adhesive application equipment technology, specifically an automatically controlled integrated cold bending adhesive application production line. Background Technology

[0002] In the manufacturing of building components such as door and window frames, cold bending production lines are often used to continuously process steel coils into rectangular ring-shaped steel plates with specific cross-sectional shapes. To meet the requirements for sealing, shock absorption, and protection, black sealing strips are usually applied to specific edges of the workpiece. Therefore, an adhesive application device is integrated into the final stage of the cold bending production line, forming an integrated production line. The function of the adhesive application device is to continuously, accurately, and tightly adhere the rolled adhesive strips to the edges of the moving workpiece.

[0003] Existing adhesive application devices suffer from unstable tension control of the adhesive strip during application. The strip is often unwound passively, with tension roughly adjusted through friction. Due to constantly changing roll diameter and fluctuating mechanical resistance, the strip tension is highly susceptible to inconsistencies. Excessive tension stretches the strip, narrowing it or even causing it to break; insufficient tension results in loose strips, wrinkles, or misalignment during application, severely impacting application quality. Furthermore, when workpiece width or length specifications change, the symmetrically arranged application mechanism must be re-aligned. Current equipment often relies on manual loosening of fasteners and repeated cranking of the screw with a wrench to adjust the spacing on both sides. This adjustment method is time-consuming, inefficient, and highly dependent on operator experience, making it difficult to ensure consistent strip adhesion. Cold-bent workpieces exhibit slight warping, uneven thickness, and deviation during transport. Fixed application heads cannot move in real-time, easily leading to strip misalignment and incomplete application, resulting in defective products. Moreover, existing adhesive applications generally use mechanical adhesive strips containing chemical components, which can cause significant damage to the hands and lungs of long-term operators. Summary of the Invention

[0004] The purpose of this invention is to provide an automatically controlled integrated cold bending and adhesive application production line to solve the problems of unstable adhesive strip tension control and the inability to adjust the adhesive application distance according to the workpiece size in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatically controlled integrated cold bending and adhesive application production line, comprising a conveying mechanism, on which several sets of adhesive application mechanisms are symmetrically arranged; The adhesive application mechanism includes a moving component, a distance adjustment component, a sensing component, an unwinding component, and an adhesive strip. The moving component is equipped with a distance adjustment component. One end of the distance adjustment component is equipped with an unwinding component and a sensing component in sequence along the processing direction. The unwinding component is equipped with an adhesive strip. One end of the adhesive strip is sleeved on the unwinding component, and the other end of the adhesive strip is tightly attached to the workpiece being processed. The sensing component includes a pressure roller, a rotating frame, and a camera. The pressure roller is fitted around the outer ring of the rotating frame, and the pressure roller and the rotating frame are rotatably connected. The camera is positioned above the pressure roller. The moving components are placed on both sides of the conveying mechanism, the rotating frame and the adjusting component are hinged together, and a camera is provided on one side of the adjusting component.

[0006] After molding, the workpiece is moved to the adhesive application mechanism via a conveying mechanism. The adhesive application mechanism applies adhesive strips to the workpiece surface. The distance adjustment component can adjust the application distance between two symmetrical sets of adhesive strips according to the width of the workpiece. The sensing component is used to monitor the tension of the adhesive strip during the application process. The adhesive strip is unwound by the unwinding component. After unwinding, the foremost adhesive strip is located below the pressure roller and is applied to the workpiece by the pressure of the pressure roller. During operation, the tension of the adhesive strip will drive the rotating frame to rotate around the hinge point, causing the pressure roller to produce a corresponding displacement. The camera detects the position change of the pressure roller and can then provide feedback on the tension level. This controls the moving component to slide and adjust the position of the entire unwinding component. When the tension is too high, the moving component moves the unwinding component towards the adhesive application position, reducing the distance between the adhesive application position and the unwinding component, thereby loosening the adhesive strip and preventing damage or breakage due to excessive tension. When the tension is too low, the unwinding component moves away from the adhesive application position, increasing the distance between the adhesive application position and the unwinding component, thereby tightening the adhesive strip and achieving real-time tension adjustment.

[0007] Furthermore, the moving component includes a motor, a slide rail, and a slider. The motor is located on one side of the slide rail, and a lead screw is located at the output end of the motor. The slide rail and the lead screw are rotatably connected, the slide rail and the slider are slidably connected, the slider and the lead screw are threadedly connected, and the slider is provided with a protrusion. The unwinding assembly includes an unwinding drum, a rotating roller, and a guide plate. The unwinding drum, the rotating roller, and the guide plate are arranged sequentially along the processing direction, and the rotating roller is provided in several groups. The conveying mechanism is equipped with a slide rail, and a pitch adjustment component is fitted on the raised outer ring. The unwinding drum, rotating roller and guide plate are all placed on one side of the pitch adjustment component. The guide plate and the pitch adjustment component are hinged. The rubber strip is conveyed around the outer ring of several rotating rollers, and the guide plate is placed below the rubber strip.

[0008] After the workpiece passes through the adjusting assembly, the rubber strip is drawn out from the unwinding drum and sequentially passes through multiple sets of alternately arranged rotating rollers. After being stably guided, it is led out through the guide plate to ensure a smooth conveying path for the rubber strip. The pressure roller presses the rubber strip and adheres it to the workpiece surface. The camera detects the position change of the pressure roller and provides feedback on the tension. The moving assembly controls the entire unwinding assembly to slide and adjust its position. The drive motor drives the lead screw to rotate, which in turn drives the slider to move back and forth along the slide rail. Thus, the slider drives the entire adjusting assembly and the unwinding assembly to move synchronously, thereby achieving position adjustment during the tension adjustment process.

[0009] Furthermore, the adhesive applicator also includes a guiding assembly and a pressing assembly, with the pressing assembly and the spacing adjustment assembly arranged sequentially along the conveying direction; The adjustable distance assembly includes a telescopic cylinder, and the rod end of the telescopic cylinder is provided with a support plate; The guiding assembly includes a guide frame, on which a shaped plate is provided. The shaped plate is provided with a guide ramp and a guide plane in sequence along the processing direction. The clamping assembly includes a clamping bracket and a clamping roller, which are rotatably connected. The clamping assembly is fixed to the conveying mechanism, the cylinder end of the telescopic cylinder is located on the slider protrusion, and a guide frame is provided on one side of the support plate.

[0010] Before applying the adhesive, the workpiece first passes under the clamping assembly. As it passes, the workpiece lifts the clamping roller around the clamping bracket, and the clamping roller continues to press on the workpiece, keeping it stable in the vertical direction. Then, the workpiece reaches the position of the adjusting assembly. The adjusting assembly moves the support plate through the telescopic cylinder, which can drive the unwinding assembly to adjust its position. In conjunction with the guide slope of the irregular plate on the guide assembly, when the workpiece width changes, the workpiece slides along the guide slope, compressing the telescopic cylinders on both sides until the guide planes on both sides press the workpiece, automatically adapting to the workpiece width and keeping the workpiece stable in the horizontal direction, ensuring accurate adhesive application and eliminating the need for manual adjustment.

[0011] Furthermore, the adhesive applicator also includes a cutting component; The cutting assembly includes a connecting frame, a telescopic component below the connecting frame, and a cutting blade below the telescopic component; A connecting bracket is provided on one side of the support plate, the cutter is placed above the end of the rubber strip, and a camera is provided on one side of the cutter.

[0012] Once the adhesive strip is applied to the workpiece and reaches the end of the workpiece, the camera recognizes that the adhesive application is complete. It then drives the telescopic component under the connecting frame to extend downwards, causing the cutter to move down and cut the adhesive strip, thus completing a single adhesive application operation. This eliminates the need for manual cutting and further enhances the automation level of the processing.

[0013] Furthermore, the conveying mechanism includes a longitudinal roller conveyor and a transverse roller conveyor, with the conveying directions of the longitudinal roller conveyor and the transverse roller conveyor arranged perpendicularly, and the inlet end of the transverse roller conveyor located at the outlet end of the longitudinal roller conveyor.

[0014] The longitudinal roller conveyor is used to move the workpiece along the processing direction to complete the adhesive application on both long sides of the workpiece. When the workpiece reaches the end of the longitudinal roller conveyor, it automatically enters the transverse roller conveyor. The transverse roller conveyor changes the conveying direction of the workpiece and sends it to the adhesive application mechanism to complete the adhesive application on the other two short sides, realizing automatic and continuous adhesive application around the ring-shaped workpiece. Two sets of adhesive application mechanisms are symmetrically arranged on both sides of the longitudinal roller conveyor, and two other sets of adhesive application mechanisms are symmetrically arranged on both sides of the transverse roller conveyor, corresponding to the adhesive application requirements of the long and short sides of the workpiece, respectively.

[0015] Furthermore, the outlet end of the transverse roller conveyor is provided with a feeding mechanism, which includes a feeding robotic arm and a collection frame. The feeding robotic arm is located on one side of the transverse roller conveyor, and the collection frame is located on one side of the feeding robotic arm.

[0016] After the processed ring-shaped workpiece is conveyed out of the transverse roller conveyor, the unloading robotic arm grabs the workpiece and neatly places the glued workpiece into the collection box, completing the entire processing flow, further improving the automation level of the production line and reducing the amount of manual unloading work.

[0017] Furthermore, the integrated cold bending and adhesive application production line also includes a feeding mechanism and a forming mechanism, which are arranged sequentially according to the processing direction.

[0018] The steel coil raw material is output by the feeding mechanism and gradually fed into the forming mechanism. After the workpiece is formed, it is then transported to the adhesive application mechanism by the conveying mechanism for adhesive application, realizing the integrated processing of the entire process from raw material to finished product.

[0019] Furthermore, the feeding mechanism includes a steel coil unloading machine, a leveling device, and a butt welding machine, which are arranged sequentially according to the processing direction.

[0020] The coil unloading machine releases the raw steel coils, the leveling device levels and shapes the coils, relieving bending stress, and the welding machine connects the end of the previous coil to the beginning of the next coil, ensuring continuous production. The coils are then conveyed to the forming mechanism to complete the next process.

[0021] Furthermore, the forming mechanism includes a punching machine, a cold bending forming machine, and a shearing machine, which are arranged sequentially according to the processing direction.

[0022] After the steel coil enters the forming mechanism, the punching machine first punches out the corresponding mounting holes, then the cold bending forming machine gradually bends it into the required cross-sectional shape, and finally the shearing machine cuts it to the set length to obtain the workpiece blank to be glued, which is ready for the subsequent glue application process.

[0023] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention uses a hinged pressure roller to convert the tension of the rubber strip into a displacement, performs non-contact precise measurement through a camera, and drives the entire unwinding assembly to actively relax or tighten, forming a real-time closed-loop tension adjustment system, reducing relaxation or breakage, and ensuring smooth bonding and accurate positioning of the rubber strip; 2. This invention can adapt to the width between the adhesive strips. Under the action of the telescopic cylinder, its guide plane always adheres to the edge of the workpiece with constant pressure. When the width of the workpiece changes, it is automatically squeezed apart. Whether the long side is glued or the short side is glued after a corner, the device can follow instantly, eliminating the step of manually adjusting the width. The efficiency and convenience of production changeover are improved, the harm caused by the adhesive strips to workers is reduced, and safety is increased. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example: Figures 1-9 As shown, the present invention provides a technical solution: an automatically controlled integrated production line for cold bending and adhesive application.

[0028] like Figures 1-4 As shown, an automatically controlled cold bending and adhesive application integrated production line includes a conveying mechanism 1, on which several sets of adhesive application mechanisms 2 are symmetrically arranged. The adhesive application mechanism 2 includes a moving component 21, an adjusting component 22, a sensing component 23, an unwinding component 24, and an adhesive strip 25. The moving component 21 is provided with the adjusting component 22. One end of the adjusting component 22 is provided with the unwinding component 24 and the sensing component 23 in sequence along the processing direction. The unwinding component 24 is provided with an adhesive strip 25. One end of the adhesive strip 25 is sleeved on the unwinding component 24, and the other end of the adhesive strip 25 is tightly attached to the workpiece being processed. The sensing component 23 includes a pressure roller 231, a rotating frame 232 and a camera 233. The pressure roller 231 is sleeved on the outer ring of the rotating frame 232, and the pressure roller 231 and the rotating frame 232 are rotatably connected. The camera 233 is placed above the pressure roller 231. The moving component 21 is placed on both sides of the conveying mechanism 1, the rotating frame 232 and the adjusting component 22 are hinged, and a camera 233 is provided on one side of the adjusting component 22.

[0029] After molding, the workpiece is moved to the adhesive application mechanism 2 via the conveying mechanism 1. The adhesive application mechanism 2 applies the adhesive strip 25 to the surface of the workpiece. The distance adjustment component 22 can adjust the application distance between the two symmetrical sets of adhesive strips 25 according to the width of the workpiece. The sensing component 23 is used to monitor the tension of the adhesive strip 25 during the application process. The adhesive strip 25 is unwound by the unwinding component 24. After unwinding, the foremost adhesive strip 25 is located below the pressure roller 231 and is applied to the workpiece by the pressure of the pressure roller 231. During operation, the tension of the adhesive strip 25 will drive the rotating frame 232 to rotate around the hinge point, causing the pressure roller 231 to generate... Corresponding to the displacement, the camera 233 detects the position change of the pressure roller 231 and can then provide feedback on the tension. It controls the moving component 21 to drive the entire unwinding component 24 to slide and adjust its position. When the tension is too high, the moving component 21 drives the unwinding component 24 to move towards the adhesive application position, reducing the distance between the adhesive application position and the unwinding component 24, thereby loosening the adhesive strip 25 and preventing the adhesive strip 25 from being damaged or broken due to excessive tension. When the tension is too low, the unwinding component 24 is driven away from the adhesive application position, increasing the distance between the adhesive application position and the unwinding component 24, thereby tightening the adhesive strip 25 and achieving real-time tension adjustment.

[0030] like Figures 5-6 As shown, the moving component 21 includes a motor 211, a slide rail 212 and a slider 213. The motor 211 is provided on one side of the slide rail 212, and a lead screw is provided at the output end of the motor 211. The slide rail 212 and the lead screw are rotatably connected. The slide rail 212 and the slider 213 are slidably connected. The slider 213 and the lead screw are threadedly connected. The slider 213 is provided with a protrusion. The unwinding assembly 24 includes an unwinding drum 241, a rotating roller 242, and a guide plate 243. The unwinding drum 241, the rotating roller 242, and the guide plate 243 are arranged sequentially along the processing direction. The rotating roller 242 is provided with several groups. The conveying mechanism 1 is equipped with a slide rail 212, and a pitch adjustment component 22 is fitted on the raised outer ring. The unwinding drum 241, the rotating roller 242 and the guide plate 243 are all placed on one side of the pitch adjustment component 22. The guide plate 243 and the pitch adjustment component 22 are hinged. The rubber strip 25 is conveyed around the outer ring of several rotating rollers 242, and the guide plate 243 is placed below the rubber strip 25.

[0031] After the workpiece passes through the adjusting assembly 22, the rubber strip 25 is drawn out from the unwinding drum 241 and passes through multiple sets of alternately arranged rotating rollers 242 in sequence. After being stably guided, it is led out through the guide plate 243 to ensure a smooth conveying path for the rubber strip 25. The pressure roller 231 presses the rubber strip 25 and attaches it to the workpiece surface. The camera 233 detects the position change of the pressure roller 231 and provides feedback on the tension. The moving assembly 21 is controlled to drive the entire unwinding assembly 24 to slide and adjust its position. The drive motor 211 drives the lead screw to rotate, which can drive the slider 213 to move back and forth along the slide rail 212. Thus, the slider 213 drives the entire adjusting assembly 22 and the unwinding assembly 24 to move synchronously, thereby realizing the position adjustment during the tension adjustment process.

[0032] like Figures 5-7 As shown, the adhesive applicator 2 also includes a guide assembly 26 and a pressing assembly 28, with the pressing assembly 28 and the spacing adjustment assembly 22 arranged sequentially along the conveying direction; The adjustable distance assembly 22 includes a telescopic cylinder 221, and the rod end of the telescopic cylinder 221 is provided with a support plate 222; The guide assembly 26 includes a guide frame 261, on which a shaped plate 262 is provided. The shaped plate 262 is provided with a guide slope 2621 and a guide plane 2622 in sequence along the processing direction. The clamping assembly 28 includes a clamping bracket 281 and a clamping roller 282, which are rotatably connected. The clamping assembly 28 is fixed on the conveying mechanism 1, the cylinder end of the telescopic cylinder 221 is located on the protrusion of the slider 213, and a guide frame 261 is provided on one side of the support plate 222.

[0033] Before applying the adhesive, the workpiece first passes under the clamping assembly 28. As it passes, the workpiece lifts the clamping roller 282 around the clamping bracket 281. The clamping roller 282 continues to press on the workpiece, keeping it stable in the vertical direction. Then, the workpiece reaches the position of the adjusting assembly 22. The adjusting assembly 22 moves the support plate 222 through the telescopic cylinder 221, which can drive the unwinding assembly 24 to adjust its position. In conjunction with the guide slope 2621 of the irregular plate 262 on the guide assembly 26, when the workpiece width changes, the workpiece slides along the guide slope 2621, compressing the telescopic cylinders 221 on both sides until the guide planes 2622 on both sides press the workpiece, automatically adapting to the workpiece width and keeping the workpiece stable in the horizontal direction, ensuring accurate adhesive application position and eliminating the need for manual adjustment.

[0034] like Figures 4-5 As shown, the adhesive applicator 2 also includes a cutting component 27; The cutting assembly 27 includes a connecting frame 271, a telescopic member 272 is provided below the connecting frame 271, and a cutter 273 is provided below the telescopic member 272. A connecting bracket 271 is provided on one side of the support plate 222, and a cutter 273 is placed above the end of the adhesive strip 25. A camera 233 is provided on one side of the cutter 273.

[0035] Once the adhesive is applied to the workpiece, the adhesive strip 25 reaches the end of the workpiece. The camera 233 recognizes that the adhesive application is complete and drives the telescopic component 272 under the connecting frame 271 to extend downward, which in turn moves the cutter 273 downward to cut the adhesive strip 25, completing a single adhesive application operation without the need for manual cutting, further improving the degree of automation in the processing.

[0036] like Figure 8As shown, the conveying mechanism 1 includes a longitudinal roller conveyor 11 and a transverse roller conveyor 12. The conveying directions of the longitudinal roller conveyor 11 and the transverse roller conveyor 12 are arranged perpendicularly, and the inlet end of the transverse roller conveyor 12 is located at the outlet end of the longitudinal roller conveyor 11.

[0037] The longitudinal roller conveyor 11 is used to move the workpiece along the processing direction to complete the adhesive application on both long sides of the workpiece. When the workpiece moves to the end of the longitudinal roller conveyor 11, it automatically enters the transverse roller conveyor 12. The transverse roller conveyor 12 changes the conveying direction of the workpiece and sends it into the adhesive application mechanism 2 to complete the adhesive application on the other two short sides, realizing automatic and continuous adhesive application around the annular workpiece. Two sets of adhesive application mechanisms 2 are symmetrically arranged on both sides of the longitudinal roller conveyor 11, and two other sets of adhesive application mechanisms 2 are symmetrically arranged on both sides of the transverse roller conveyor 12, respectively corresponding to the adhesive application requirements of the long and short sides of the workpiece.

[0038] like Figure 8 As shown, the outlet end of the transverse roller conveyor 12 is provided with a feeding mechanism 3. The feeding mechanism 3 includes a feeding robotic arm 31 and a collection frame 32. The feeding robotic arm 31 is placed on one side of the transverse roller conveyor 12, and the collection frame 32 is placed on one side of the feeding robotic arm 31.

[0039] After the processed annular workpiece is conveyed out of the transverse roller conveyor 12, the unloading robot arm 31 grabs the workpiece and neatly places the glued workpiece into the collection box 32, completing the entire processing flow, further improving the automation level of the production line and reducing the workload of manual unloading.

[0040] like Figure 9 As shown, the cold bending and adhesive bonding integrated production line also includes a feeding mechanism 4 and a forming mechanism 5. The feeding mechanism 4, forming mechanism 5, conveying mechanism 1 and unloading mechanism 3 are arranged in sequence according to the processing direction.

[0041] The steel coil raw material is output by the feeding mechanism 4 and gradually fed into the forming mechanism 5. After the workpiece is formed, it is then transported to the adhesive application mechanism 2 by the conveying mechanism 1 for adhesive application, realizing the integrated processing of the entire process from raw material to finished product.

[0042] like Figure 9 As shown, the feeding mechanism 4 includes a steel coil unloading machine 41, a leveling device 42, and a butt welding machine 43, which are arranged in sequence according to the processing direction.

[0043] The steel coil unloading machine 41 is used to unload the raw steel coil, the leveling device 42 levels and shapes the steel coil to remove bending stress, and the welding machine 43 is used to connect the end of the previous steel coil to the beginning of the next steel coil to ensure continuous production. After that, the steel coil is conveyed to the forming mechanism 5 to complete the next process.

[0044] like Figure 9 As shown, the forming mechanism 5 includes a punching machine 51, a cold bending forming machine 52, and a shearing machine 53, which are arranged sequentially according to the processing direction.

[0045] After the steel coil enters the forming mechanism 5, the punching machine 51 first punches out the corresponding mounting holes, then the cold bending forming machine 52 gradually bends it into the required cross-sectional shape, and finally the shearing machine 53 cuts it according to the set length to obtain the workpiece blank to be glued, which is ready for the subsequent glue application process.

[0046] Working principle of the invention: This production line starts processing raw steel coils. First, the raw material is released by the steel coil unloading machine 41. The steel coil is then leveled by the leveling device 42 to remove coiling stress. Then, the first and last steel coils are connected by the welding machine 43 to ensure continuous production. After that, the coils are conveyed to the forming mechanism 5. The coils are punched by the punching machine 51, cold-bent forming machine 52, and sheared to a fixed length by the shearing machine 53 to obtain the formed workpiece. The workpiece is then sent to the conveying mechanism 1. First, it enters the longitudinal roller conveyor 11 and is conveyed along the length direction. During the movement of the workpiece, the two adhesive application mechanisms 2 work together to complete the adhesive application on the two long sides. Then, the workpiece is transferred to the transverse roller conveyor 12. After the conveying direction is changed, the other two sets of adhesive application mechanisms 2 complete the adhesive application on the two short sides, realizing the automatic adhesive application around the entire circumference of the annular workpiece. After the adhesive application is completed, the unloading robot arm 31 grabs the workpiece and puts it into the collection frame 32, completing the entire process.

[0047] During the adhesive application process, the pressure roller 231 keeps the adhesive strip 25 pressed against the workpiece surface. When the tension of the adhesive strip 25 changes, it drives the hinged rotating frame 232 to rotate, causing the pressure roller 231 to move accordingly. After the camera 233 detects the change in displacement, it feeds back the tension and controls the motor 211 of the moving component 21 to drive the slider 213 to move as a whole, which drives the unwinding component 24 to move back and forth synchronously, adjusting the distance between the unwinding position and the adhesive application position, thereby achieving real-time tension adjustment and preventing the adhesive strip 25 from being pulled apart or loosened and misaligned. When the workpiece width changes, the front end of the workpiece will push open the guide slope 2621, driving the guide components 26 on both sides to adaptively compress the telescopic cylinder 221 until the guide planes 2622 on both sides adhere to the edge of the workpiece with constant pressure, automatically adapting to the workpiece width without manual adjustment, greatly improving the convenience of production changeover. After the adhesive application is completed, the telescopic component 272 extends and drives the cutter 273 to move down, automatically cutting the adhesive strip 25, waiting for the next workpiece to enter the adhesive application process.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
