Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing equipment technology, specifically to a flexible material edge sealing equipment. Background Technology
[0002] To prevent thermal runaway in the power batteries of new energy vehicles caused by continuous and repeated charging and discharging of the cells, thermal insulation pads are usually placed between the cells to isolate heat conduction and simultaneously provide buffering and sealing functions. However, existing thermal insulation pad materials cannot simultaneously meet the performance requirements of heat insulation, flame retardancy, buffering, and sealing. Therefore, in actual manufacturing, flame-retardant adhesive is usually sprayed around the edges of the thermal insulation pad material to reinforce its function. In existing technologies, the edge sealing equipment for thermal insulation pad composite materials mainly relies on manual adjustment. This is complex and cumbersome, and it is difficult to adapt to the high-precision edge sealing of materials with different thicknesses and sizes. Furthermore, manual adjustment is inevitably subject to errors caused by human factors, further resulting in low edge sealing accuracy.
[0003] Furthermore, existing adhesive application processes mostly use rollers or scrapers, which easily lead to uneven adhesive layer thickness and adhesive overflow at the edges. Moreover, the cooling and curing process of existing adhesive application equipment is time-consuming and inefficient, requiring a long waiting period before subsequent processing can begin. Additionally, the edge finishing of existing adhesive application equipment largely relies on manual trimming, which is time-consuming, labor-intensive, and has low trimming accuracy. In short, existing adhesive application processes and sealing equipment suffer from problems such as low adhesive layer thickness accuracy, long cooling times for product sealing and appearance quality, irregular edge finishing (easily leading to seal failure and appearance defects), and low production efficiency. Utility Model Content
[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a flexible material edge sealing device. This device can use thermal insulation pad composite materials of different thicknesses and sizes, and can precisely control the thickness and uniformity of the sealing layer, thereby improving the sealing performance and appearance quality of the thermal insulation pad. In addition, this device can effectively accelerate the cooling and curing process, shorten the production cycle, and improve sealing efficiency.
[0005] The objective of this utility model is achieved through the following technical solution: An edge sealing device for flexible materials includes a feeding and positioning component, a clamp conveying component, an adhesive application component, a cooling component, and an edge treatment component. The feeding and positioning component includes a feeding platform, a limiting plate, and an infrared sensor. The feeding platform is an electric lifting platform with a limiting plate at its rear and an infrared sensor on one side. The clamp conveying component includes a pneumatic clamp, a linear guide rail, and a servo drive module. The pneumatic clamp is slidably mounted on the linear guide rail and is located directly above the feeding platform. The servo drive module is mounted on the linear guide rail and is used to drive the pneumatic clamp to translate along the linear guide rail. The adhesive application component, cooling component, and edge treatment component are arranged sequentially along the linear guide rail away from the limiting plate.
[0006] Based on further optimization of the above scheme, the pneumatic clamp includes a positioning plate, two elastic grippers, and a drive cylinder. The two elastic grippers are slidably disposed on the surface of the positioning plate (the two elastic grippers can move towards or away from each other on the surface of the positioning plate). The bottom surface of the positioning plate is located directly above the end face of the loading platform, and the side of the positioning plate away from the infrared sensor is slidably disposed on a linear guide rail. The drive cylinder is disposed corresponding to the elastic grippers and is connected to the elastic grippers. The drive cylinder controls the elastic grippers to slide towards or away from each other on the end face of the positioning plate.
[0007] Based on further optimization of the above scheme, a silicone layer is provided on the side where the elastic grippers are close to each other.
[0008] Based on further optimization of the above scheme, the glue application assembly includes a mounting block, a translation mechanism, a first lifting mechanism, and a glue gun. A mounting beam is provided on the upper side of the linear guide rail, the mounting block is provided on the mounting beam, the translation mechanism is provided on the side of the mounting block away from the mounting beam, and the first lifting mechanism is provided at the end of the translation mechanism away from the mounting block. The glue gun is provided at the bottom end of the first lifting mechanism.
[0009] Based on further optimization of the above scheme, the cooling component includes two cooling plates and a limiting baffle. The two cooling plates are symmetrically arranged on the lower side of the mounting beam, and the two cooling plates are driven by cylinders to clamp the upper edge of the heat insulation pad. The limiting baffle is raised and lowered by a second lifting mechanism installed on the mounting beam to flatten the adhesive layer.
[0010] Based on further optimization of the above scheme, the corner processing component includes a third lifting mechanism, a positioning template and two corner-pinching molds. The third lifting mechanism is set on the installation beam and the positioning template is set at the lower end of the third lifting mechanism. Two corner-pinching molds are symmetrically set on the positioning template and the shape of the bottom of the corner-pinching molds that are close to each other matches the corner of the heat insulation pad material.
[0011] The following are the technical effects of this utility model: This application utilizes a feeding and positioning assembly consisting of a feeding platform, a limiting plate, and an infrared sensor. This assembly not only initially limits the heat insulation pad material through the translation of the limiting plate but also feeds the material through the lifting and lowering of the feeding platform. Subsequently, a clamping and conveying assembly, composed of a pneumatic clamp, a linear guide rail, and a servo drive module, triggers the pneumatic clamp to clamp the material when the infrared sensor detects material during its ascent. The linear guide rail and servo drive module then drive the pneumatic clamp holding the heat insulation pad material sequentially towards the adhesive application assembly, cooling assembly, and edge treatment assembly for adhesive application, cooling, and edge treatment. This not only ensures the adhesive thickness and prevents overlapping or discontinuous adhesive lines during application, ensuring the consistency and uniformity of the adhesive layer, but also accelerates adhesive curing and prevents deformation through the synergistic clamping and cooling process. This achieves the goal of single-positioning and continuous multi-station processing, reducing errors caused by repeated positioning and impacting sealing accuracy, thereby effectively improving sealing efficiency and reducing sealing time.

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Example 1: A flexible material edge sealing device includes a feeding and positioning assembly, a clamp conveying assembly, an adhesive application assembly, a cooling assembly, and an edge treatment assembly. The feeding and positioning assembly includes a feeding platform 11, a limiting plate 12, and an infrared sensor 13. The feeding platform 11 is an electric lifting platform (a conventional electric lifting platform in this field is acceptable), and the rear side of the feeding platform 11 (i.e., Figure 1 The upper left side shown Figure 2 A limiting plate 12 is provided on the lower left side (as shown). (The limiting plate 12 can be moved along the linear guide rail 22 to ensure that the limiting plate 12 effectively abuts against the heat insulation pad material 80). An infrared sensor 13 is provided on one side of the loading platform 11 (multiple infrared sensors 13 can be provided, such as...). Figure 1 or Figure 2 As shown, in this embodiment, four infrared sensors are used, and any conventional model in the field can be employed.
[0018] The clamping and conveying assembly includes a pneumatic clamp, a linear guide rail 22, and a servo drive module 23. The pneumatic clamp includes a positioning plate 211, two elastic grippers 212, and a drive cylinder. The two elastic grippers 212 are slidably disposed on the surface of the positioning plate 211 (the two elastic grippers 212 can move towards or away from each other on the surface of the positioning plate 211). The bottom surface of the positioning plate 211 is located directly above the end face of the loading platform 11 (a through groove is opened in the middle of the bottom surface of the positioning plate 211 corresponding to the thickness of the heat insulation pad material 80, so that the heat insulation pad material 80 can pass through), and the side of the positioning plate 211 away from the infrared sensor 13 is slidably disposed on the linear guide rail 22. The drive cylinder is disposed corresponding to the elastic grippers 212 and is connected to the elastic grippers 212. The drive cylinder controls the elastic grippers 212 to move towards each other on the end face of the positioning plate 211. Or, slide away (ensuring the clamping force is adjustable between 50 and 200 N to adapt to the heat insulation pad material 80 with a thickness of 0.5 to 5 mm); the servo drive module 23 is set on the linear guide rail 22 and is used to drive the pneumatic clamp to translate along the linear guide rail 22 (that is, the servo drive module 23 drives the positioning plate 211 set on the linear guide rail 22 to realize the translation of the pneumatic clamp. The servo drive module 23 can adopt a conventional structure combination in the art, such as: a combination of servo motor and lead screw. In this embodiment, no further limitations are made. The translation speed of the pneumatic clamp driven by the servo drive module 23 is 0.5 to 2 m / min); a silicone layer is set on the side of the elastic grippers 212 that are close to each other (a conventional silicone material in the art can be used to avoid damage to the heat insulation pad material 80 during the clamping process of the elastic grippers 212).
[0019] The glue application assembly, cooling assembly, and edge treatment assembly are arranged sequentially along the linear guide rail away from the limiting plate. The glue application assembly includes a mounting block 31, a translation mechanism 32, a first lifting mechanism 33, and a glue gun 34. A mounting beam 70 is provided on the upper side of the linear guide rail 22. The mounting block 31 is mounted on the mounting beam 70. The translation mechanism 32 is provided on the side of the mounting block 31 away from the mounting beam 70, and the first lifting mechanism 33 is provided at the end of the translation mechanism 32 away from the mounting block 31 (both the translation mechanism 32 and the first lifting mechanism 33 can be mechanically driven by servo motors, which are used to drive the first lifting mechanism 33 with the glue gun 34 to translate away from the mounting block 31 and to move the glue gun 34 downward, so that the bottom end of the glue gun 34 is directly above the end face of the heat insulation pad material 80). The glue gun 34 is provided at the bottom end of the first lifting mechanism 33. The cooling assembly includes two cooling plates 41 and a limiting baffle 42. The two cooling plates 41 are symmetrically arranged on the lower side of the mounting beam 70, and the two cooling plates 41 are driven by cylinders to clamp the upper edge of the heat insulation pad (the cooling plates 41 have built-in semiconductor cooling chips, and the temperature can be set between 5 and 30°C), and are controlled by a closed loop temperature sensor. The limiting baffle 42 is raised and lowered by a second lifting mechanism 420 installed on the mounting beam 70 (the second lifting mechanism 420 can be a conventional pneumatic lifting mechanism), thereby flattening the adhesive layer. The corner treatment assembly includes a third lifting mechanism 51, a positioning template 52, and two corner-pinching molds 53. The third lifting mechanism 51 is mounted on the mounting beam 70, and the positioning template 52 is located at the lower end of the third lifting mechanism 51. Two corner-pinching molds 53 are symmetrically arranged on the positioning template 52 (the spacing between the two corner-pinching molds 53 can be adjusted on the positioning module 52 to accommodate heat insulation pad materials 80 of different thicknesses). The shape of the bottom side of the corner-pinching molds 52 that is close to each other matches the corner of the heat insulation pad material 80 (e.g., ...). Figure 1 or Figure 2 (As shown).
[0020] Operating procedures: First, the composite material of the double-sided PET / PE encapsulation film (i.e., the heat insulation pad material 80) is placed on the loading platform 11, with the left side of the material adhering to the initial limiting position. The operator inputs the material length L, width W, and thickness H. Simultaneously, the operator controls the limiting plate 12 to move to the target positioning position (W - reserved margin) to complete the X-axis positioning. The loading platform 11 rises to the trigger height of the infrared sensor 13, confirming that the material is in position in the Y-axis, stops the rise of the loading platform 11, and triggers the pneumatic clamp preparation signal. At this time, the elastic gripper 211 is located in the lower middle part of the heat insulation pad material 80. The elastic gripper 211 moves towards the side that is closer to each other to complete the clamping of the heat insulation pad material 80. The clamping force is automatically adjusted according to the material thickness (F=H×50N / mm). The loading platform 11 descends and resets, and the pneumatic clamp moves along the linear guide rail 22 to transport the material to the adhesive coating station at a preset speed (0.5~2m / min). After the material enters the adhesive application area, the position of the glue gun 34 is adjusted by controlling the translation mechanism 32 and the first lifting mechanism 33 to position it directly above the material end face (simultaneously, the thickness h of the material edge can be scanned by a laser thickness sensor to obtain the adhesive application width, for example: spray width = h + 0.2 mm, spray pressure = h × 0.1 MPa, spray speed = conveying speed × 0.8), and the spray path is parallel to the material boundary; after the adhesive application is completed, the material continues to be conveyed to the next cooling station. When the material reaches the cooling station, the two cooling plates 41 are driven by cylinders to clamp the material edge (clamping force = h × 0.2 MPa); the limiting baffle 42 moves down to 0.1 mm above the material + adhesive layer surface to flatten the adhesive layer; the cooling system of the cooling plate 41 is activated to keep its temperature closed-loop controlled at a preset value (5~30℃), and cooling is maintained for 10~15 seconds until the temperature control feedback adhesive layer temperature drops to ≤30℃ (which can be monitored in real time by an external temperature sensor), at which point curing is determined to be complete. While the material is cooling and solidifying, it enters the corner-pinching station. The corner-pinching position (5mm from both ends) is calculated according to the set length L. Two corner-pinching molds 53 are simultaneously pressed down pneumatically. The mold pressure is controlled at 0.5MPa and the action time is 1s. The sharp edge is used for mechanical corner-pinching. After corner-pinching is completed, the mold automatically resets, completing the complete process of "material loading-adhesive application-cooling-corner-pinching".
[0021] Example 2: As another preferred embodiment, based on the above embodiment 1, in order to facilitate the support of the heat insulation pad material 80 during the cooling and corner-pinching process, the end of the linear guide 22 away from the feeding and positioning component is provided with a support component 60, which is mainly a support groove (e.g., Figure 1 or Figure 2 As shown), the support groove is located at the top center and is slidably mounted on the linear guide rail 22. The end of the support groove near the feeding and positioning component is configured as an opening structure with a gradually decreasing width (as shown). Figure 1 (As shown).
[0022] Example 3: As another preferred embodiment, based on the above-described embodiment 1, in order to facilitate the handling and storage of the entire sealing equipment and avoid the influence of the external environment, such as... Figure 3 As shown: The sealing equipment is equipped with a protective shell on the outside, and an operation window is set at the top center of the protective shell. Two double cabinet doors are set on the protective shell below the operation window.
