Description

Technical Field

[0001] The present invention relates to the technical field of automotive interior trim covering, and specifically to an automotive interior trim covering device and a covering process. Background Art

[0002] The rapid development of the automotive industry has led to a year-on-year increase in the production volume of automotive interior trim products. New technologies, new materials, and new processes have emerged continuously and been widely applied in the automotive field, significantly enhancing the power performance, economy, safety, and comfort of automobiles. To meet the users' demands for automotive interior comfort, the automotive manufacturing industry often adopts the method of covering veneer materials such as leather or fabric on the interior trim panels.

[0003] When using an automotive interior trim covering device, first turn on the power of the device and preheat it to the set temperature. At the same time, install and debug the mold, prepare the interior trim and the covering material, and if necessary, preheat the material; then fix the interior trim on the workbench or the corresponding fixture, place the covering material on the interior trim and align the edges, and start the device. The device will automatically press the covering material onto the interior trim to complete the covering.

[0004] Existing automotive interior trim covering devices use manual loading and unloading, resulting in low and unstable production efficiency, making it difficult to meet the requirements of large-scale production. Moreover, the position alignment depends on manual operation, with insufficient accuracy, and problems such as poor adhesion between the covering material and the interior trim, wrinkles, and bubbles are likely to occur, affecting the appearance and performance.

[0005] Therefore, we make improvements in this regard and propose an automotive interior trim covering device and a covering process. Summary of the Invention

[0013] A number of fixed bases are fixedly connected to the surface of the load-bearing rod, the number of fixed bases are arranged in a linear array on the load-bearing rod, and vacuum suckers are provided on the surface of the fixed bases;

[0014] A protective net is fixedly connected to a position on the surface of the support frame parallel to the toothed belt, and a top cover is fixedly connected to the bottom of the support frame;

[0015] Further included is a covering structure, the covering structure including a bearing plate slidably connected to the support frame, a guiding groove opened on the surface of the bearing plate, sliders fixedly connected to the four corners of the bearing plate, a power control element with one end fixedly connected to the slider and the other end fixedly connected to the top cover, and a film covering assembly fixedly connected to the bearing plate.

[0016] Among them, the transmission assembly includes a second driving roller respectively fixedly connected to the surface of the second runner, a transmission belt in frictional connection with the surface of the second driving roller, the transmission belt passing through the support frame and extending to the side away from the second driving roller, and fixing frames with one end fixedly connected to the outer peripheral plate are movably connected to both ends of the second driving roller.

[0017] Among them, one end of the transmission belt away from the second driving roller is in frictional connection with a second driven roller, inner support plates and outer support plates are respectively fixedly connected to both ends of the second driven roller, and the ends of the inner support plates and the outer support plates away from the second driven roller are respectively fixedly connected to the outer peripheral plate.

[0018] Among them, the film covering assembly includes two lifting members I fixedly connected to the carrier plate and located at symmetrical positions, a film covering roller rotatably connected between the two lifting members I, two lifting members II fixedly connected to the side of the guiding groove, and a guiding roller rotatably connected between the two lifting members II;

[0019] The surface of the peripheral plate is fixedly connected with a vacuum base, and the surface of the vacuum base is provided with suction heads.

[0020] Among them, two lifting members III are fixedly connected to the carrier plate at symmetrical positions with the lifting members II, a collecting roller is rotatably connected between the two lifting members III, and a second motor is arranged at one end of the collecting roller;

[0021] The surface of the carrier plate is fixedly connected with a slide rail, the surface of the slide rail is slidably connected with a heating plate, and a calibration camera is arranged on the surface of the carrier plate between the slide rails.

[0022] The covering process of the automotive interior part covering equipment includes the following steps:

[0023] Step 1: Start the first motor to drive the first driving roller and the toothed belt to rotate, the positioning assembly moves, and at the same time, drive the second driving roller to rotate through the first runner, the belt and the second runner. The interior part is conveyed. After the balance block and the load-bearing column on the positioning assembly pass through the sensing head, a signal is transmitted to the induction base;

[0024] Step 2: The induction base controls the telescopic rod in the hydraulic column to rise, the fixed base and the vacuum suction cup lift the interior part. After the gravity sensing device in the fixed base senses, the vacuum suction cup adsorbs the interior part for positioning. After the calibration camera observes that the interior part enters the planned space, the first motor stops working;

[0025] Step 3: The film covering assembly works. The film is installed on the film covering roller and one end passes through the guiding groove and the guiding roller and is installed on the collecting roller. After the interior part stops in the planned area, the heating plate slides between the carrier plate and the film to heat the film. The power control element controls the carrier plate to slide to wrap the film on the interior part. At the same time, the suction heads on the vacuum base work to make the film wrap the interior part;

[0026] Step 4: The film on the surface of the interior part after covering is cut. At this time, the positioning assembly is higher than the conveyor belt. After cutting, the first motor works again. When the balance block and the load-bearing column pass through the sensing head on the side of the second driven roller, the hydraulic column controls the telescopic rod to descend, the vacuum suction cup releases, and the wrapped interior part is placed on the conveyor belt and waits to be collected and processed.

[0027] Advantages of the present invention: Through the cooperation of the transmission structure and the positioning component, the interior trim can be automatically transported and positioned without manual intervention. The first motor drives the first driving roller and the toothed belt to rotate, driving the positioning component to move. At the same time, the first runner, the belt, and the second runner drive the second driving roller to rotate, enabling the interior trim to be stably transported on the conveyor belt, realizing automatic loading and unloading, effectively improving production efficiency, and reducing labor costs. When the balance block and the load-bearing column on the positioning component pass through the induction head on the sensing base, the data control module receives the signal and transmits it to the sensing base, thereby controlling the telescopic rod in the hydraulic column to perform precise upward telescopic actions, using the fixed base and the vacuum suction cup to lift and preliminarily position the interior trim. Subsequently, the calibration camera further observes the position of the interior trim to ensure its accurate entry into the planned space, causing the first motor to stop working and completing high-precision positioning. This positioning method where the sensing and hydraulic systems work together effectively avoids position deviations caused by manual positioning and improves the wrapping accuracy. During the wrapping process, the heating plate slides in the slide rail between the bearing plate and the peritoneal film to heat the peritoneal film, making the peritoneal film softer and having better adhesion, facilitating its close adhesion to the surface of the interior trim. The power control element precisely controls the sliding of the bearing plate on the support frame to ensure that the film can be evenly and tightly wrapped around the interior trim, reducing the generation of wrinkles and bubbles and effectively improving the wrapping quality.

[0040] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings of the specification.

[0041] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0042] Second, the "one embodiment" or "embodiment" referred to herein means a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they embodiments that are mutually exclusive of other embodiments individually or selectively.

[0043] Third, the present invention is described in detail in conjunction with schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be locally enlarged out of the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, the actual production should include three-dimensional spatial dimensions of length, width, and depth.

[0044] Embodiment 1, referring to Figures 1 - 7 , which is the first embodiment of the present invention, provides an automotive interior trim covering device. This device includes a support frame 100, and an outer peripheral plate 101 is fixedly connected to the bottom of the support frame 100;

[0045] A fixing structure, the fixing structure includes an outer guard plate 200 fixedly connected to the outer peripheral plate 101, an inner guard plate 201 fixedly connected to the outer peripheral plate 101 and in a symmetric position with the outer guard plate 200, a first motor 202 is provided at one end of the outer guard plate 200 and the inner guard plate 201, a first driving roller 203 fixedly connected to the end of the first motor 202 close to the inner guard plate 201, a toothed belt 204 frictionally connected to the surface of the first driving roller 203, a sensing base 205 fixedly connected to the inner guard plate 201 and located on the side of the toothed belt 204, a sensing head 208 fixedly connected to the sensing base 205, and a positioning assembly 206 fixedly connected to the toothed belt 204 and arranged in a linear array on the toothed belt 204;

[0046] The support frame 100 serves as the basis for the entire device, providing a platform for installing and supporting other components, ensuring the stability and integrity of the device. The setting of the outer peripheral plate 101 can increase the rigidity of the support frame 100, prevent vibration or deformation during operation, and thus ensure the smooth operation of the device.

[0047] The symmetrical design of both the outer guard plate 200 and the inner guard plate 201 helps to balance the force on the equipment and improve the structural stability. The motor 202 set at one end provides the power source for the operation of the equipment. The connection between the driving roller 203 and the motor 202 ensures the efficient transmission of power, enabling the toothed belt 204 to rotate stably. The friction connection method of the toothed belt 204 can effectively prevent slipping and ensure the accuracy of transmission. The setting of the sensing base 205 and the sensing head 208 can monitor the position and operating state of the toothed belt 204 in real time, providing data support for the automatic control of the equipment. The positioning component 206 can move precisely in the support frame 100 driven by the toothed belt 204 to achieve accurate positioning of the interior trim parts. When the two motors 202 work, the rotation frequencies of the inner shafts are the same, and then drive the two driving rollers 203 to rotate at the same frequency.

[0048] The transmission structure includes a runner 300 fixedly connected to the side of the motor 202 close to the toothed belt 204, a belt 301 rotatably connected to the surface of the runner 300, a runner 302 rotatably connected to the belt 301, and a transmission component 303 fixedly connected to the runner.

[0049] The power of the motor 202 can be transmitted to the driving roller 304, and then drive the operation of the conveyor belt 305. The driving roller 304 and the conveyor belt 305 in the transmission component 303 constitute the transmission channel of the interior trim parts, enabling the interior trim parts to move stably in the equipment. The setting of the driven roller 309 provides support for the conveyor belt 305 and ensures the tension and smoothness of the conveyor belt 305.

[0050] Among them, the positioning component 206 includes a connecting plate 209 fixedly connected to the toothed belt 204, two induction bases 210 fixedly connected to the connecting plate 209 and symmetrically located on the surface of the connecting plate 209, two hydraulic columns 212 arranged on the surface of any one of the two induction bases 210, a telescopic rod 213 telescopically connected to the surface of the hydraulic column 212, and a balance block 214 fixedly connected to the end of the telescopic rod 213 away from the hydraulic column 212. The two balance blocks 214 are fixedly connected by a bridging plate 211.

[0051] Among them, a spring 215 is arranged on the surface of the telescopic rod 213 between the balance block 214 and the hydraulic column 212. A load-bearing column 216 is fixedly connected to the surface of the balance block 214 away from the telescopic rod 213. One end of the load-bearing column 216 is fixedly connected to a support base 217. Load-bearing rods 218 are respectively fixedly connected to both sides of the support base 217. One end of the toothed belt 204 away from the driving roller 203 is frictionally connected to a driven roller 207.

[0052] The positioning component 206 includes a connecting plate 209, an induction base 210, a hydraulic column 212, a telescopic rod 213, a balance weight 214, etc. These components work together to achieve precise lifting and positioning of the interior trim. The setting of the spring 215 can absorb a certain impact force, making the movement of the balance weight 214 smoother. The structures of the load-bearing column 216, the support base 217, and the load-bearing rod 218 provide a stable support platform for the interior trim. The combination of the fixed base 219 and the vacuum suction cup 220 can firmly adsorb the interior trim, ensuring its accurate position during the covering process.

[0053] Among them, a plurality of fixed bases 219 are fixedly connected to the surface of the load-bearing rod 218, and the plurality of fixed bases 219 are arranged in a linear array on the load-bearing rod 218. A vacuum suction cup 220 is arranged on the surface of the fixed base 219; a protective net 103 is fixedly connected to a position parallel to the toothed belt 204 on the surface of the support frame 100, and a top cover 102 is fixedly connected to the bottom of the support frame 100. After the gravity sensing device in the fixed base 219 senses the gravity of the interior trim, it controls the vacuum suction cup 220 to adsorb and position the interior trim, further ensuring the position accuracy of the interior trim during the covering process. This double-guarantee positioning method can effectively prevent the interior trim from shifting during the covering process and improve the stability of the covering quality.

[0054] The protective net 103 at a position parallel to the toothed belt 204 on the surface of the support frame 100 can effectively prevent foreign objects from entering the equipment and protect the safety of operators at the same time. The setting of the top cover 102 helps to enclose the equipment and reduce the influence of dust and other pollutants on the internal components.

[0055] Among them, the transmission component 303 includes a second driving roller 304 fixedly connected to the surface of the second runner 302 respectively. A transmission belt 305 is frictionally connected to the surface of the second driving roller 304. The transmission belt 305 penetrates through the support frame 100 and extends to the side away from the second driving roller 304. Both ends of the second driving roller 304 are movably connected to a fixing frame 306 with one end fixedly connected to the peripheral plate 101. One end of the transmission belt 305 away from the second driving roller 304 is frictionally connected to a second driven roller 309. Both ends of the second driven roller 309 are respectively fixedly connected to an inner support plate 307 and an outer support plate 308. One ends of the inner support plate 307 and the outer support plate 308 away from the second driven roller 309 are respectively fixedly connected to the peripheral plate 101. When an object is placed on the transmission belt 305, the vacuum suction cup 220 will firmly adsorb the object. As the toothed belt 204 moves, the hydraulic cylinder 212 and the telescopic rod 213 in the positioning component 206 will be adjusted according to the size and shape of the object to ensure the precise positioning of the object. At the same time, the cooperation of the belt 301 and the second runner 302 continuously transports the object to the designated position. During the transmission process, the protective net 103 and the top cover 102 provide additional protection to ensure the safety and reliability of the operation. Finally, the object is accurately transported to the target position to complete the entire work process.

[0056] During use, when the first motor 202 starts and is stably supported by the outer protection plate 200 and the inner protection plate 201, the two motors cooperate to drive the first driving roller 203 to rotate. With the assistance of the first driven roller 207, the toothed belt 204 starts to rotate smoothly, thereby driving the positioning component 206 to move smoothly within the support frame 100. At the same time, the rotational energy of the first motor 202 is transmitted through the first runner 300, the belt 301, and the second runner 302 to further drive the second driving roller 304 to rotate. With the support of the second driven roller 309, the two transmission belts 305 start to stably convey the interior trim parts, realizing the continuous and smooth movement of the interior trim parts on the transmission belt 305.

[0057] When the balance weight 214 and the load-bearing column 216 in the positioning component 206 pass by the sensing head 208 of the sensing base 205, the data control module will immediately capture this signal and transmit it to the induction base 210. Subsequently, the induction base 210 will instruct the telescopic rod 213 in the hydraulic cylinder 212 to perform a precise upward telescopic action, using the fixed base 219 and the vacuum suction cup 220 to firmly lift the interior trim parts on the transmission belt 305. Once the gravity sensing device of the fixed base 219 senses the gravity of the interior trim parts, the vacuum suction cup 220 will be quickly activated to firmly adsorb and position the interior trim parts.

[0058] During this process, the calibration camera 413 continuously monitors the movement of the interior trim part to ensure its precise entry into the preset planned space. Once the interior trim part completely enters the planned space, the first motor 202 will receive a stop command, thus ending the entire transmission and positioning process. It not only realizes the automatic transmission and precise positioning of the interior trim part, but also ensures the smoothness and continuity of the interior trim part during transmission through the stable conveyor belt 305 system. More importantly, it realizes the automatic loading and unloading of the interior trim part, greatly improving the production efficiency and significantly reducing the labor cost.

[0059] Example 2, referring to Figures 1 - 10 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that it further includes a covering structure. The covering structure includes a bearing plate 400 slidably connected to the support frame 100, a guide groove 401 opened on the surface of the bearing plate 400, sliders 4001 fixedly connected to the four corners of the bearing plate 400, a power control element 402 with one end fixedly connected to the slider 4001 and the other end fixedly connected to the top cover 102, and a film covering assembly 403 fixedly connected to the bearing plate 400.

[0060] Through the slidably connected bearing plate 400 and the power control element 402, the position of the film covering assembly 403 can be flexibly adjusted to adapt to interior trim parts of different sizes or shapes. At the same time, the settings of the guide groove 401 and the sliders 4001 ensure the smoothness and accuracy of the movement of the bearing plate 400.

[0061] Compared with Embodiment 1, further, the film covering assembly 403 includes two lifting members one 404 fixedly connected to the bearing plate 400 and in symmetric positions, a film covering roller 405 rotatably connected between the two lifting members one 404, two lifting members two 406 fixedly connected to the side of the guide groove 401, and a guide roller 407 rotatably connected between the two lifting members two 406; the cooperation of the film covering roller 405 and the guide roller 407 can achieve uniform film covering of the interior trim part, improving the quality and efficiency of film covering. At the same time, the settings of the lifting members one 404 and the lifting members two 406 ensure the stability and position accuracy of the interior trim part during the film covering process.

[0062] The surface of the peripheral plate 101 is fixedly connected with a vacuum base 500, and a suction head 501 is arranged on the surface of the vacuum base 500. It is convenient to firmly cover the film on the interior trim part.

[0063] Further, two lifting members three 408 are fixedly connected to the bearing plate 400 and in symmetric positions with the lifting members two 406, a collecting roller 409 is rotatably connected between the two lifting members three 408, and a second motor 410 is arranged at one end of the collecting roller 409;

[0064] The surface of the carrier plate 400 is fixedly connected with a slide rail 411. The surface of the slide rail 411 is slidably connected with a heating plate 412. A calibration camera 413 is arranged on the surface of the carrier plate 400 between the slide rails 411. The cooperation of the slide rail 411 and the heating plate 412 can realize the heat treatment of the interior trim parts, enhancing the adhesion between the film covering material and the interior trim parts. At the same time, the introduction of the calibration camera 413 can monitor the position and film covering situation of the interior trim parts in real time, ensuring the accuracy and reliability of the film covering process.

[0065] During the use process, before the film covering operation starts, the film covering material needs to be properly installed on the film covering roller 405 first, and ensure that the other end of it smoothly passes through the guiding groove 401 and the guiding roller 407, and is finally fixed on the collecting roller 409. Subsequently, when the interior trim part accurately stops at the preset area space, the two heating plates 412, under the guidance of the slide rail 411, smoothly move to between the carrier plate 400 and the film covering, and preheat the film covering area to be wrapped. At this time, the power control element 402 precisely controls the carrier plate 400 to slide along the support frame 100, tightly attaching the film covering to the surface of the interior trim part. Meanwhile, the suction heads 501 on the vacuum base 500 are immediately activated, and with their strong adsorption force, ensure that the film covering can be tightly and firmly wrapped on the interior trim part.

[0066] After the film covering operation is completed, the cutter on the equipment will precisely cut the film covering on the surface of the interior trim part. It should be noted that the entire positioning component 206 is designed to be higher than the height of the conveyor belt 305 during design to ensure the smooth progress of the cutting operation. After the cutting is completed, the first motor 202 restarts. As the balance weight 214 and the load-bearing column 216 slowly pass by the sensing head 208 on the support frame 100 on one side of the driven roller two 309, the hydraulic column 212 immediately instructs the telescopic rod 213 to descend. At the same time, the vacuum suction cup 220 releases its adsorption force in a timely manner, and places the perfectly wrapped interior trim part smoothly and safely on the conveyor belt 305, waiting for subsequent collection and processing.

[0067] It not only significantly improves the automation degree of the film covering of the interior trim parts, but also ensures the quality and aesthetics of the film covering through preheating treatment and precise cutting. At the same time, by the perfect combination of vacuum adsorption and hydraulic control, the smoothness and safety of the interior trim parts during the transmission process are realized, greatly reducing the difficulty and risk of manual operation, effectively improving the production efficiency, and saving valuable labor costs for the enterprise.

[0068] The remaining structures are the same as those of Embodiment 1.

[0069] The covering process of the automotive interior trim part covering equipment includes the following steps:

[0070] Step 1: Power on the first motor 202. Supported by the outer guard plate 200 and the inner guard plate 201, the first motor 202 starts to work. The first motor 202 drives the first driving roller 203 to rotate. Supported by the first driven roller 207, the toothed belt 204 rotates. The toothed belt 204 drives the entire positioning assembly 206 to move in the support frame 100. At the same time, the rotation of the first motor 202 drives the second driving roller 304 to rotate through the first runner 300, the belt 301 and the second runner 302. Supported by the second driven roller 309, the interior parts on the two conveyor belts 305 are conveyed. When the balance weight 214 and the load-bearing column 216 on the positioning assembly 206 pass by the sensor head 208 on the sensor base 205, the data control module of the entire device will transmit the sensed signal to the induction base 210;

[0071] Step 2: The induction base 210 controls the telescopic rod 213 in the hydraulic column 212 to extend upward. The fixed base 219 and the vacuum suction cup 220 are used to lift the interior parts on the conveyor belt 305. After the gravity sensing device in the fixed base 219 senses the gravity, it controls the vacuum suction cup 220 to adsorb and position the interior parts. When the calibration camera 413 observes that the entire interior part enters the planned space, the first motor 202 stops working;

[0072] Step 3: The film covering assembly 403 starts to work. First, before working, the film is installed on the film covering roller 405, and the other end passes through the guide groove 401 and the guide roller 407 and is installed on the collecting roller 409. When the interior part stops in the planned area space, the two heating plates 412 slide in the slide rail 411 and slide between the bearing plate 400 and the film, heating the film in the working area. The power control element 402 controls the bearing plate 400 to slide on the support frame 100 to cover the film on the interior part. At the same time, the suction head 501 on the vacuum base 500 will work to facilitate firmly covering the film on the interior part;

[0073] Step 4: After the film on the surface of the covered interior part is cut by the cutter on the device, the height of the entire positioning assembly 206 should be higher than the height of the conveyor belt 305. After cutting, the first motor 202 starts to work. When the balance weight 214 and the load-bearing column 216 pass by the sensor head 208 on the support frame 100 near the second driven roller 309, while the hydraulic column 212 controls the telescopic rod 213 to descend, the vacuum suction cup 220 starts to release, and the wrapped interior part is smoothly placed on the conveyor belt 305, waiting for subsequent collection and processing.
