Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automatic adhesive pressing device for the underbody protection plate of a new energy vehicle. Background Technology

[0002] As the core power source, the battery of a new energy vehicle is often protected by a bottom plate when the vehicle is driving on complex road conditions, such as bumpy roads, gravel roads, or potholes.

[0003] In the production of the bottom cover plate for new energy vehicle batteries, attaching insulating film is a crucial step in ensuring its protective performance. However, currently, this process involves manually rolling the film repeatedly with rollers to achieve adhesion between the film and the bottom cover plate surface. This manual rolling is prone to uneven application, resulting in a loose bond between the insulating film and the bottom cover plate, which in turn reduces the protective effect of the bottom cover plate. Utility Model Content

[0004] The main purpose of this utility model is to propose an automatic adhesive pressing device for the underbody protection plate of new energy vehicles, which aims to solve the technical problem that the underbody protection plate and the insulating adhesive are easily not tightly bonded when manually rolled by rollers in the existing technology.

[0005] To achieve the above objectives, this utility model proposes an automatic adhesive pressing device for the underbody protection plate of new energy vehicles, comprising: The frame is equipped with a conveying mechanism. One end of the conveying mechanism is a loading and unloading station, and the other end is a pressure holding station.

[0021] Please refer to Figure 1 and Figure 2 This utility model provides an automatic adhesive pressing device for the underbody protection plate of a new energy vehicle, comprising: The frame 100 is equipped with a conveying mechanism 200. One end of the conveying mechanism 200 is a loading and unloading station 210, and the other end of the conveying mechanism 200 is a pressure holding station 220. The loading and unloading station 210 is equipped with a material carrier 300 that is movably connected to the conveying mechanism 200. The material carrier 300 is used to support the bottom guard plate. The pressure holding mechanism 400 is located at the pressure holding station 220. The pressure holding mechanism 400 includes a pressure holding plate 410 located above the conveying mechanism 200 and a lifting assembly 420 connected to the pressure holding plate 410.

[0022] The frame 100 serves as the basic support component of the entire device, providing a stable mounting platform for other mechanisms and ensuring that none of the components will shift or sway due to stress during operation. The frame 100 can be made of aluminum alloy or steel, as long as it possesses sufficient strength and rigidity to withstand the mechanical loads during movement; this invention does not impose any limitations on its material.

[0023] The main function of the conveying mechanism 200 is to convey the bottom guard plate to the pressure holding mechanism 400. One end of the conveying mechanism 200 is equipped with a material carrier 300 for manual or robotic loading. The conveying mechanism 200 can be a slider with a guide rail, a servo motor with a lead screw, or a servo motor with a belt, etc. As long as the conveying mechanism 200 can drive the material carrier 300 to perform linear repetitive motion, this invention is not limited to any particular type.

[0024] The function of the material carrier 300 is to support the bottom guard plate, which is conveyed by the conveying mechanism 200 to the pressure holding mechanism 400 for pressing. Its shape can be rectangular, and its size is larger than that of the bottom guard plate. This is to ensure that the entire bottom guard plate is placed completely on the material carrier 300. When the pressure holding mechanism 400 presses the bottom guard plate, the bottom guard plate can be evenly stressed, avoiding bending due to lack of support at the edges, which would reduce the product yield.

[0025] The main function of the pressure-holding mechanism 400 is to further press the insulating film pre-adhered to the surface of the bottom protective plate, ensuring that the insulating film can be firmly adhered to the bottom protective plate for long-term protection when subsequently applied to the battery. In this embodiment, the pressure-holding mechanism 400 is located at one end of the conveying mechanism 200, that is, one end of the conveying mechanism 200 is the loading / unloading station 210, and the other end is the pressure-holding station 220, with the pressure-holding mechanism 400 located at the pressure-holding station 220. Furthermore, the pressure-holding mechanism 400 includes a pressure-holding plate 410 disposed above the conveying mechanism 200 and a lifting assembly 420. The shape of the pressure-holding plate 410 can be rectangular, elliptical, etc., and this invention does not impose any limitations.

[0026] The main function of the lifting assembly 420 is to drive the pressure plate 410 to move up and down, so as to move the pressure plate 410 closer to or away from the bottom guard plate on the material carrier 300. The lifting assembly 420 can be in the form of a cylinder or a motor and belt, as long as it can realize the linear repetitive movement of the pressure plate 410. This utility model does not impose any restrictions here.

[0027] After the bottom cover plate is manually loaded onto the material carrier 300, it is conveyed by the conveyor mechanism 200 to the pressure holding station 220 at the other end. The pressure holding plate 410 is driven by the lifting component 420 to begin descending until it contacts the entire bottom cover plate for pressure holding. After the pressure holding time is preset, the pressure holding plate 410 is driven by the lifting component 420 to rise back to the initial position. The conveyor mechanism 200 drives the material carrier 300 back to the loading and unloading station 210, where it is manually unloaded. Then, a new bottom cover plate is loaded, and a new round of adhesive bonding process is performed.

[0028] This invention features a conveying mechanism 200 and a pressure-holding mechanism 400 on a frame 100. The bottom protective plate is placed on a material carrier 300 and automatically conveyed from the loading / unloading station 210 to the pressure-holding station 220 by the conveying mechanism 200. The pressure-holding plate 410 is driven down by the lifting assembly 420 to contact the entire bottom protective plate, ensuring that the insulating film on the entire surface of the bottom protective plate is evenly pressed, improving the adhesion between the insulating film and the bottom protective plate, and enhancing the protective performance of the bottom protective plate.

[0029] Please refer to Figure 3 and Figure 4 The conveying mechanism 200 includes: Two guide rails 230 are spaced apart on the frame 100, and a conveying drive component 240 connected to the material carrier 300 is provided between the two guide rails 230. The bottom of the material carrier 300 is provided with at least two sliders 250 that are slidably connected to the two guide rails 230, and the at least two sliders 250 are respectively located on both sides of the bottom of the material carrier 300.

[0030] Two guide rails 230 are spaced apart on the frame 100, serving as the movement tracks for the material carrier 300. They can be made of high-strength steel to ensure good straightness and wear resistance, providing a stable guiding foundation for the sliding of the material carrier 300. A conveying drive component 240, located between the two guide rails 230 and connected to the material carrier 300, can be a servo motor-driven chain, synchronous belt, or ball screw structure. As long as it can control the moving speed and position of the material carrier 300 and achieve linear movement, this utility model does not impose any limitations.

[0031] At least two sliders 250 are located on both sides of the bottom of the material carrier 300, and are slidably connected to two guide rails 230. Each slider 250 has a groove that engages with the guide rail 230 for sliding. The number of sliders 250 can be 2, 4, or 6. For example, two sliders 250 can be provided, one on each side of the bottom of the material carrier 300. Alternatively, six sliders 250 can be provided, three on each side of the bottom of the material carrier 300, which further enhances the pressure resistance of the sliders 250 on the material carrier 300, preventing damage to the sliders 250 under prolonged pressure and thus affecting the automated conveying of the bottom guard plate.

[0032] Once the bottom guard plate is placed on the material carrier 300, the material carrier 300 begins to move. The two guide rails 230 provide strict constraints on the slider 250, ensuring that the material carrier 300 always moves along a preset straight trajectory without lateral deviation. When the material carrier 300 needs to stop directly below the pressure holding mechanism 400, the conveyor drive 240 brakes precisely according to preset position parameters, accurately positioning the material carrier 300 and preparing it for the subsequent pressing operation of the pressure holding mechanism 400. After pressing is completed, the conveyor drive 240 restarts, driving the material carrier 300 back along the guide rails 230 to the unloading / loading station 210 to load new bottom guard plates.

[0033] In some embodiments, the conveying drive 240 is a conveying cylinder; please refer to... Figure 3 The conveying cylinder is horizontally positioned between the two guide rails 230. The cylinder body of the conveying cylinder is fixedly connected to the frame 100. The piston rod of the conveying cylinder passes through the bottom of the material carrier 300 and is connected to the side of the material carrier 300.

[0034] The conveying cylinder is horizontally positioned between the two guide rails 230. The cylinder body can be fixed to the frame 100 by bolts or other fasteners. This fixing method ensures that the cylinder will not be displaced due to the extension and retraction of the piston rod during operation, providing a stable foundation for power output and facilitating future maintenance and replacement.

[0035] In this embodiment, the piston rod moves in the space below the material carrier 300. When the material carrier 300 moves to the pressure holding position 220, the cylinder body of the conveying cylinder is also located below the material carrier 300, which can make full use of the idle space of the device and improve the compactness of the device.

[0036] This invention employs a conveying cylinder powered by compressed air. Its rapid extension and retraction action quickly starts and stops the material carrier 300. Compared to chain or ball screw drives, this reduces mechanical transmission lag, improves the response speed of the material carrier 300, and thus enhances the overall efficiency of the device. Furthermore, the conveying cylinder provides stable and controllable power output. By adjusting the compressed air pressure, the force with which the piston rod pushes the material carrier 300 can be precisely controlled, preventing excessive power from causing severe impacts during startup or shutdown. This protects components such as the material carrier 300, guide rail 230, and slider 250, extending their service life. It also ensures the stability of the bottom guard plate during conveying, guaranteeing the accuracy of subsequent adhesive bonding operations.

[0037] Please refer to Figure 2 and Figure 5 The pressure holding mechanism 400 also includes: Mounting bracket 430 is located above conveying mechanism 200. Pressure plate 410 is detachably connected to the side of mounting bracket 430 facing conveying mechanism 200. Lifting component 420 is connected to the side of mounting bracket 430 facing away from conveying mechanism 200.

[0038] The main function of the mounting bracket 430 is to mount the pressure holding plate 410. It can be made of welded square steel or assembled from aluminum alloy profiles to ensure that it will not deform when subjected to the driving force of the lifting component 420 and the reaction force during the pressure holding process. The detachable connection between the pressure holding plate 410 and the mounting bracket 430 can be a bolt connection, a snap-fit ​​connection, etc., and this utility model does not impose any restrictions on this.

[0039] Once the material carrier 300, carrying the bottom protective plate, reaches below the pressure holding mechanism 400, the lifting assembly 420 is activated, driving the mounting frame 430 and the pressure holding plate 410 fixed on the mounting frame 430 to move downwards synchronously. Driven by the mounting frame 430, the pressure holding plate 410 gradually approaches the insulating film on the surface of the bottom protective plate until it makes full contact with the insulating film and applies a preset pressure. During the preset pressure holding time, the mounting frame 430 provides stable support for the pressure holding plate 410, ensuring that the pressure is continuously and evenly transmitted to the insulating film. After the pressure holding is completed, the lifting assembly 420 reverses its direction, driving the mounting frame 430 and the pressure holding plate 410 to return to their original positions, awaiting the next pressure holding cycle.

[0040] Because the pressure plate 410 and the mounting bracket 430 are detachably connected, when it is necessary to replace the pressure plate 410 with a corresponding specification for different models and sizes of bottom guard plates, the operator does not need to make large-scale adjustments to the entire pressure holding mechanism 400. They only need to remove the old pressure plate 410 and install the new one, which greatly shortens the changeover time of the device, improves the response speed of the device to different production needs, and enhances the versatility of the equipment.

[0041] Please continue to refer to this. Figure 2 and Figure 5 The pressure holding mechanism 400 also includes: The fixing bracket 440 is located above the mounting bracket 430. Both the fixing bracket 440 and the mounting bracket 430 are rectangular structures, and a guide hole is provided at each of the four corners of the mounting bracket 430. Guide posts 450, four guide posts 450 are provided, one end of any guide post 450 passes through the guide hole and is connected to the frame 100, and the other end of the guide post 450 is connected to the side of the fixed frame 440 facing the mounting frame 430; There are four guide sleeves 460, which are respectively located at the four corners of the mounting bracket 430 on the side opposite the fixed bracket 440. The guide sleeves 460 are slidably connected to the guide posts 450.

[0042] Four guide posts 450 correspond to the four corners of the mounting bracket 430. One end passes through the guide hole of the mounting bracket 430 and is fixedly connected to the frame 100, while the other end is connected to the side of the fixed bracket 440 opposite to the mounting bracket 430, forming a vertical support structure from the frame 100 to the fixed bracket 440. Four guide sleeves 460 correspond one-to-one with the guide posts 450 and are installed at the four corners of the mounting bracket 430 opposite to the fixed bracket 440. Their inner diameter is slightly larger than the diameter of the guide posts 450 to ensure that the guide sleeves 460 can slide flexibly along the guide posts 450. The guide sleeves 460 and the mounting bracket 430 can be connected by bolts, which ensures the stability of the connection between the two and facilitates disassembly and replacement.

[0043] When the lifting assembly 420 drives the mounting frame 430 to move up and down, the guide sleeves 460 at the four corners of the mounting frame 430 slide synchronously along the corresponding guide posts 450. Since the guide posts 450 are fixed at both ends to the frame 100 and the fixed frame 440 respectively, their positions remain unchanged, forming a stable vertical guide path. During the descent of the mounting frame 430, the guide sleeves 460 move downwards along the guide posts 450, restricting the mounting frame 430 to move only in the vertical direction, preventing horizontal offset or rotation due to uneven force or external interference. When the mounting frame 430 rises and resets, the guide sleeves 460 also slide upwards along the guide posts 450, continuing to play a guiding role and ensuring that the mounting frame 430 always maintains a stable movement trajectory. The fixed frame 440, through its connection to the top of the guide posts 450, provides top support for the guide posts 450, enhancing the overall rigidity of the guide posts 450 and preventing bending or swaying of the guide posts 450 during the movement of the mounting frame 430, further improving the stability of the guide.

[0044] In some embodiments, the lifting assembly 420 includes: Multiple lifting cylinders are provided, with the cylinder bodies of the multiple lifting cylinders located on the side of the fixed frame 440 facing away from the mounting frame 430. The fixed frame 440 is provided with clearance holes for the lifting cylinders, and the piston rods of the lifting cylinders pass through the clearance holes and are connected to the mounting frame 430.

[0045] In this embodiment, five lifting cylinders are evenly distributed on the fixed frame 440. The driving force applied to the mounting frame 430 by the piston rod is transmitted to the mounting frame 430 from multiple points, making the thrust on each part of the mounting frame 430 more balanced. Compared with single-cylinder drive, this multi-point drive method can effectively avoid deformation of the mounting frame 430 due to concentrated force, and ensure that the pressure applied by the pressure plate 410 to the insulating film is evenly distributed across the entire contact surface, further improving the bonding quality of the insulating film.

[0046] The mounting bracket 440 has a clearance hole corresponding to the position of each lifting cylinder. The diameter of the clearance hole is slightly larger than the diameter of the piston rod of the lifting cylinder. This provides a channel for the extension and retraction of the piston rod and also plays a certain guiding role for the piston rod, preventing excessive deviation of the piston rod during movement.

[0047] Please refer to Figure 3 and Figure 4 The bottom of the material rack 300 is provided with a number of first support blocks 310 at intervals, and the side of the frame 100 near the pressure holding mechanism 400 is provided with a corresponding number of second support blocks 110.

[0048] Multiple first support blocks 310 at the bottom of the material carrier 300 are spaced apart. Their material can be high-strength alloy or hard engineering plastic, possessing good compressive strength and wear resistance, and capable of withstanding the pressure during the pressure-holding process. The first support blocks 310 are fixed to the bottom of the material carrier 300 by bolts or welding, forming a stable whole with the material carrier 300. Each first support block 310 has the same height to avoid uneven stress on the material carrier 300 due to differences in the height of the first support blocks 310.

[0049] The frame 100 has a corresponding number of second support blocks 110 at the pressure holding station 220. These blocks can be made of high-strength alloy or hard engineering plastic, possessing good pressure resistance and wear resistance, and can withstand the pressure during the pressure holding process. When the material carrier 300 moves to the pressure holding station 220, the positions of the second support blocks 110 correspond one-to-one with the positions of the first support blocks 310, and the two can precisely abut against each other to support the material carrier 300.

[0050] When the conveyor drive 240 moves the material carrier 300 along the guide rail 230 to the pressure holding station 220 below the pressure holding mechanism 400, the first support block 310 at the bottom of the material carrier 300 will align and abut against the second support block 110 on the frame 100. At this time, the material carrier 300 forms double support in the vertical direction, relying on the contact between the bottom slider 250 and the guide rail 230, and also obtaining additional support through the abutment between the first support block 310 and the second support block 110. During the pressure holding process, it can effectively counteract the downward pressure applied by the pressure holding plate 410, avoid deformation of the material carrier 300 due to force concentration, and thus prevent the bottom cover plate from bending due to the deformation of the material carrier 300, ensuring that the bottom cover plate is always in a flat state, ensuring that there are no wrinkles or gaps between the insulating film and the bottom cover plate, improving the reliability of the bonding, and enhancing the insulation and protective performance of the bottom cover plate.

[0051] Please refer to Figure 2 and Figure 3 In the conveying direction of the conveying mechanism 200, limit components 120 are respectively provided on both sides of the frame 100. The limit components 120 are located between the two guide columns 450. The mounting frame 430 can abut against the limit components 120 under the drive of the lifting component 420.

[0052] In this embodiment, the limiting component 120 includes two limiting posts. Two limiting posts are respectively provided on both sides of the frame 100 in the conveying direction of the conveying mechanism 200. These posts can be made of high-strength metal, possessing good compressive strength and wear resistance. When the mounting frame 430 descends to the preset pressure-bonding position under the drive of the lifting component 420, the bottom edge of the mounting frame 430 can precisely abut against the top of the limiting posts. Simultaneously, the limiting posts on both sides are symmetrically distributed, ensuring uniform abutment force on both sides when the mounting frame 430 descends, preventing the mounting frame 430 from tilting.

[0053] The limiting post prevents the mounting frame 430 from colliding with the material carrier 300 due to excessive descent caused by unforeseen circumstances. Once the mounting frame 430 descends to the position of the limiting post, it can no longer move down, avoiding workpiece scrap caused by excessive compression between the pressure plate 410 and the bottom guard plate, thus providing safety assurance for the production process.

[0054] Please refer to Figure 1 The frame 100 is also equipped with a protective cover 500. A passage 510 is constructed on one side of the protective cover 500. The loading and unloading station 210 is located outside the protective cover 500, and the pressure holding station 220 is located inside the protective cover 500. The material carrier 300 can move repeatedly toward the passage 510 to approach or move away from the pressure holding station 220.

[0055] The protective cover 500 on the frame 100 can be made of metal sheet or high-strength plastic, possessing a certain rigidity and protective strength, and can effectively prevent external debris from intruding. A passage 510 is specially constructed on one side, the size of which is adapted to the width and height of the material rack 300, ensuring that the material rack 300 can pass through smoothly.

[0056] The loading / unloading station 210 is located outside the protective cover 500, facilitating material handling by operators. The pressure-holding station 220, on the other hand, is located inside the protective cover 500, ensuring the pressure-holding process takes place in a relatively enclosed space, minimizing interference and improving adhesive bonding efficiency. Driven by the conveying mechanism 200, the material carrier 300 moves repeatedly along the guide rail 230 towards the opening 510, thus entering the protective cover 500 to reach the pressure-holding station 220, and exiting the protective cover 500 to reach the loading / unloading station 210.

[0057] When a pressure-holding operation is required on the bottom protective plate, the conveyor drive 240 will drive the material carrier 300 from the loading / unloading station 210 outside the protective cover 500, move along the guide rail 230 towards the opening 510, enter the interior of the protective cover 500 through the opening 510, and gradually approach the pressure-holding station 220. After the material carrier 300 is precisely moved below the pressure-holding station 220, the pressure-holding mechanism 400 located inside the protective cover 500 will start working to press the insulating film on the bottom protective plate.

[0058] During the pressure holding process, the protective cover 500 isolates the pressure holding station 220 from the outside, forming a relatively enclosed space to prevent external personnel or objects from contacting the internally working components. After the pressure holding is completed, the conveyor drive 240 drives the material carrier 300 to move in the opposite direction, exiting the protective cover 500 through the port 510 and returning to the external loading and unloading station 210. At this time, the operator can remove the bottom protective plate that has been glued and place the new bottom protective plate to be processed on the material carrier 300, waiting for the next pressure holding operation.

[0059] The protective cover 500 of this utility model effectively isolates the pressure holding station 220 from the loading / unloading station 210. When operators are working at the loading / unloading station 210, they will not come into contact with the pressure holding mechanism 400 working inside the protective cover 500, thus avoiding mechanical injury caused by accidental contact with moving parts. At the same time, debris such as insulating film fragments that may be generated during the pressure holding process are confined inside the protective cover 500 and will not splash into the loading / unloading station 210, protecting the safety of operators and greatly improving production safety.

[0060] In some embodiments, the top of the protective cover 500 is provided with a second clearance hole corresponding to the number of lifting cylinders. The lifting cylinder in this embodiment is a dual-axis double-stroke adjustable cylinder. One end of the piston rod is connected to the mounting bracket 430, and the other end extends to the outside through the second clearance hole.
