Description

Technical Field

[0001] This utility model relates to the technical field of leather covering equipment, specifically a leather covering equipment for automobile airbag production. Background Technology

[0002] As a key component of a car's passive safety system, the performance and reliability of airbags directly affect the lives of drivers and passengers. During the production of airbags, the cover of the airbag needs to be covered with leather. The leather covering of the airbag cover is an important step in the production process, which not only affects the appearance and texture of the airbag, but also has a significant impact on its deployment performance and durability. The airbag leather covering equipment is generally composed of a lower mold, a lower pressing mold, a hot pressing component, and a cold pressing component. The lower pressing mold is used to install the airbag cover.

[0003] A search revealed that patent publication number CN221851190U discloses a hot press for leather covering of automotive interior parts, including a hot press assembly, a clamping assembly movably connected to the hot press assembly, and a support assembly at the lower end of the hot press assembly. The hot press assembly includes a base, a hot press template at the upper end of the base, a fixed column fixedly connected to the base, a lower pressure plate movably connected to the fixed column, a hot press plate at the lower end of the lower pressure plate, an electrically controlled hydraulic cylinder movably connected to the upper end of the lower pressure plate, a protective sleeve on the outside of the electrically controlled hydraulic cylinder, and a cover plate at the lower end of the protective sleeve. The clamping assembly includes a fixed block, a lead screw movably connected to the inner surface of the fixed block, a connecting block threadedly connected to the lead screw, and a clamping block fixedly connected to the connecting block. By setting up the clamping assembly, rotating the lead screw drives the two clamping blocks to move simultaneously, firmly fixing the hot press template on the base, thereby preventing the hot press template from shifting during operation.

[0004] Existing leather wrapping equipment for automotive airbag production suffers from dust accumulation during the heat-pressing process between the airbag cover and the leather. This dust is easily trapped between the leather and the airbag cover, affecting their adhesion and leading to defects such as bubbles and delamination. Furthermore, dust may become embedded in the leather during heat pressing, affecting its smoothness and aesthetics, significantly compromising the product's appearance. Therefore, a new leather wrapping equipment for automotive airbag production is designed. Utility Model Content

[0005] In view of the defects or deficiencies of existing leather covering equipment, the purpose of this utility model is to provide a leather covering equipment for automobile airbag production, which can clean the area of ​​the airbag cover that is hot-pressed and covered with leather, thus avoiding the situation where dust gets trapped between the leather and the airbag cover.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a leather covering equipment for automobile airbag production, including a leather covering machine body, and a leather hot pressing mechanism for hot pressing the leather placed on the lower mold.

[0008] The leather hot pressing mechanism is equipped with a safety airbag cover pressing mold adapted to the lower mold. The leather hot pressing mechanism is also equipped with a cleaning component for cleaning the safety airbag cover installed on the safety airbag cover pressing mold. The leather hot pressing mechanism is equipped with a piston assembly for inflating the cleaning component. The leather hot pressing mechanism is also equipped with a linear movement component for driving the safety airbag cover pressing mold to move linearly in the Y-axis direction and for driving the piston assembly to move in a piston-like motion.

[0009] Preferably, a first side plate and a second side plate are installed on the upper and lower sides of one side of the outer wall of the mounting bracket, respectively, and a support frame is provided at the top of the first side plate.

[0010] Preferably, the linear motion assembly is provided with a moving plate, and a threaded hole is opened at the center of the surface of the moving plate. A rotating shaft is installed in the threaded hole, and an external thread is provided on the outer wall of the rotating shaft. The external thread on the outer wall of the rotating shaft and the threaded hole on the moving plate are connected by a threaded engagement.

[0011] Preferably, one end of the rotating shaft is installed in a bearing on the surface of the second side plate, and the other end of the rotating shaft passes through a bearing on the surface of the first side plate and is connected to a geared motor via a coupling. The geared motor is installed at the top of the support frame, and the output shaft of the geared motor passes through the top of the support frame.

[0012] The movable plate has through holes at both the front and rear ends. Guide posts are installed in the through holes, and the outer wall of the guide post is in clearance fit with the hole wall. The top and bottom ends of the guide post are respectively installed on one side surface of the first side plate and the second side plate.

[0013] Preferably, an installation plate is installed on one outer wall of the movable plate, the airbag cover pressing mold is installed on the lower surface of the installation plate, and an L-shaped pressure plate is installed on the other outer wall of the movable plate, with the other end of the L-shaped pressure plate passing through a rectangular slot on the outer wall of the mounting frame.

[0014] Preferably, the piston assembly is provided with a piston rod, one end of which is mounted on the lower surface of the L-shaped pressure plate, and the other end of which is mounted with a rubber piston. The rubber piston is disposed inside the piston cylinder. An intake pipe and an exhaust pipe are respectively provided on both sides of the lower circumferential outer wall of the piston cylinder, and a one-way valve is provided on both the intake pipe and the exhaust pipe. The piston cylinder is disposed at the bottom end of the mounting bracket.

[0015] Preferably, the cleaning assembly is provided with a tank, the air inlet on the outer circumferential wall of the tank is connected to the exhaust pipe through a conveying pipe, the air outlet on the top of the tank is provided with a diverter pipe, and the diverter pipe is connected to the nozzle through a conveying pipe, the air outlet of the tank is provided with a pressure relief valve, the tank is located at the bottom of the mounting bracket, and the nozzle is located at the bottom of the mounting plate.

[0017] In this invention, through a series of coordinated structural arrangements, when the leather hot pressing mechanism on the leather covering machine body heats the leather placed on the lower mold, the reduction motor on the linear motion component starts, causing the moving plate to move linearly in the Y-axis direction. When the moving plate moves linearly in the Y-axis direction, it drives the L-shaped pressure plate and the airbag cover pressing mold to move linearly in the Y-axis direction. When the L-shaped pressure plate moves linearly in the Y-axis direction, it drives the piston rod on the piston assembly to move linearly in the Y-axis direction. When the piston rod moves linearly in the Y-axis direction, it causes the piston assembly to move like a piston. When the piston assembly moves like a piston, it inflates the tank on the cleaning component. When a certain amount of gas is filled into the tank, the pressure relief valve on the gas outlet of the tank will automatically open. The gas in the tank will be transported to the nozzle through the diverter pipe and the conveying pipe. The nozzle will spray the gas onto the surface of the airbag cover installed on the airbag cover pressing mold to remove dust from the area of ​​the leather covered by the airbag cover heat pressing.

[0018] Therefore, before hot pressing the leather placed on the lower mold, this utility model can clean the area of ​​the leather to be hot-pressed by the airbag cover, avoiding the situation where dust will be trapped between the leather and the airbag cover, improving the fit and adhesion between the leather and the airbag cover, and improving the quality and aesthetics of the leather covering the airbag cover.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0037] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0038] like Figure 1-8 As shown, a leather covering equipment for producing automobile airbags includes a leather covering machine body 100 and a leather hot pressing mechanism 200 provided on the leather covering machine body 100 for hot pressing the leather placed on the lower mold.

[0039] The leather hot pressing mechanism 200 is equipped with an airbag cover pressing mold 240 that is adapted to the lower mold. The leather hot pressing mechanism 200 is also equipped with a cleaning component 250 for cleaning the airbag cover installed on the airbag cover pressing mold 240. The leather hot pressing mechanism 200 is equipped with a piston assembly 220 for inflating the cleaning component 250. The leather hot pressing mechanism 200 is also equipped with a linear movement component 210 for driving the airbag cover pressing mold 240 to move linearly in the Y-axis direction and for driving the piston assembly 220 to move in a piston motion.

[0040] A first side plate 232 and a second side plate 233 are respectively installed on the upper and lower sides of one side outer wall of the mounting bracket 230, and a support bracket 231 is provided at the top of the first side plate 232.

[0041] The linear motion assembly 210 is provided with a moving plate 213. A threaded hole is opened at the center of the surface of the moving plate 213. A rotating shaft 214 is installed in the threaded hole. The outer wall of the rotating shaft 214 is provided with an external thread. The external thread on the outer wall of the rotating shaft 214 and the threaded hole on the moving plate 213 are connected by a threaded engagement.

[0042] One end of the rotating shaft 214 is installed in the bearing on the surface of the second side plate 233, and the other end of the rotating shaft 214 passes through the bearing on the surface of the first side plate 232 and is connected to the geared motor 211 through a coupling. The geared motor 211 is installed at the top of the support frame 231, and the output shaft of the geared motor 211 passes through the top of the support frame 231. When the geared motor 211 starts, it will drive the rotating shaft 214 to rotate forward or in reverse. Since the external thread on the outer wall of the rotating shaft 214 is threadedly connected to the threaded hole on the moving plate 213, the rotating shaft 214 will cause the moving plate 213 to move linearly in the Y-axis direction when it rotates forward or in reverse.

[0043] The front and rear ends of the movable plate 213 are provided with through holes, and guide posts 215 are installed in the through holes. The outer wall of the guide post 215 and the hole wall of the through hole are in clearance fit. The top and bottom ends of the guide post 215 are respectively installed on one side surface of the first side plate 232 and the second side plate 233. Because the outer wall of the guide post 215 and the hole wall of the through hole are in clearance fit, the movement of the movable plate 213 can be limited and guided.

[0044] An installation plate 212 is installed on one side of the outer wall of the movable plate 213. The airbag cover pressing mold 240 is installed on the lower surface of the installation plate 212. An L-shaped pressure plate 216 is installed on the other side of the outer wall of the movable plate 213, and the other end of the L-shaped pressure plate 216 passes through the rectangular slot on the outer wall of the mounting bracket 230.

[0045] A piston rod 221 is provided on the piston assembly 220. One end of the piston rod 221 is installed on the lower surface of the L-shaped pressure plate 216, and a rubber piston 222 is installed on the other end of the piston rod 221. The rubber piston 222 is located inside the piston cylinder 223. An intake pipe 224 and an exhaust pipe 225 are respectively provided on both sides of the lower outer wall of the piston cylinder 223. Both the intake pipe 224 and the exhaust pipe 225 are equipped with one-way valves. The one-way valve on the intake pipe 224 allows the intake pipe 224 to only perform intake, and the one-way valve on the exhaust pipe 225 allows the exhaust pipe 225 to only perform exhaust. The piston cylinder 223 is located at the bottom of the mounting bracket 230. When the moving plate 213 drives the L-shaped pressure plate 216 to move linearly upward or downward in the Y-axis direction, it will cause the piston rod 221 to move linearly upward or downward in the Y-axis direction. When the piston rod 221 moves linearly upward or downward in the Y-axis direction, it will cause the piston assembly 220 to perform piston movement.

[0046] The cleaning assembly 250 is equipped with a tank 253. The air inlet on the outer circumference of the tank 253 is connected to the exhaust pipe 225 through a conveying pipe. The air outlet on the top of the tank 253 is equipped with a diverter pipe 252, which is connected to the nozzle 251 through a conveying pipe. The air outlet of the tank 253 is equipped with a pressure relief valve. When the internal pressure of the tank 253 reaches a certain level, the pressure relief valve will automatically open, and the gas in the tank 253 will flow sequentially through the diverter pipe 252 and the conveying pipe to the nozzle 251. The tank 253 is located at the bottom of the mounting bracket 230, and the nozzle 251 is located at the bottom of the mounting plate 212.

[0047] Working principle: When in use, after connecting to an external power source, when the leather hot pressing mechanism 200 on the leather covering machine body 100 heats and presses the leather placed on the lower mold, the reduction motor 211 on the linear motion assembly 210 starts, causing the moving plate 213 to move linearly in the Y-axis direction. This linear movement of the moving plate 213 in the Y-axis direction drives the L-shaped pressure plate 216 and the airbag cover pressing mold 240 to move linearly in the Y-axis direction. The L-shaped pressure plate 216 moving linearly in the Y-axis direction drives the piston rod 221 on the piston assembly 220 to move linearly in the Y-axis direction. This linear movement of the piston rod 221 causes the piston assembly 220 to perform piston movement. This piston movement of the piston assembly 220 impacts the tank 2 on the cleaning assembly 250. Inflation is performed inside the canister 253. Once a certain amount of gas is filled into the canister 253, the pressure relief valve on the outlet end of the canister 253 will automatically open. The gas inside the canister 253 will be sequentially transported to the nozzle 251 through the diverter pipe 252 and the delivery pipe. The nozzle 251 will spray the gas onto the surface of the airbag cover installed on the lower mold 240 to remove dust from the area of ​​the leather covered by the airbag cover under heat pressing. Thus, before the leather placed on the lower mold is heat pressed, the area of ​​the leather covered by the airbag cover under heat pressing can be cleaned, avoiding the situation where dust is trapped between the leather and the airbag cover. This improves the fit and adhesion between the leather and the airbag cover, and enhances the quality and aesthetics of the leather covering the airbag cover.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
