Description

Technical Field

[0001] This utility model relates to the field of sound insulation cotton cutting technology, specifically a positioning and cutting device for biomimetic honeycomb structure automotive sound insulation cotton. Background Technology

[0002] Bionic honeycomb structure automotive sound insulation cotton draws inspiration from the ingenious structure of a honeycomb to create a quiet space for drivers and passengers. It is composed of multiple layers of honeycomb material arranged in an orderly manner, with irregularly shaped, tightly connected honeycomb units. This unique structure effectively blocks external noise entering the vehicle, such as engine roar and road tire noise, through multiple reflections and absorptions. Compared to traditional sound insulation cotton, it offers superior sound insulation performance and is lighter in weight. Without increasing the vehicle's load, it significantly improves the quietness of the cabin, providing a more comfortable and pleasant driving and riding experience. This bionic honeycomb structure automotive sound insulation cotton requires specific cutting equipment during production; however, existing sound insulation cotton cutting equipment still has certain problems in its use.

[0003] For example, the cutting equipment for producing sound insulation cotton, as described in application number 202421482976.2, includes a support frame and a cutting die that is movably mounted at the top of the support frame via a lifting component. The lifting component is used to push the cutting die to slide up and down inside the support frame to cut the sound insulation cotton. A pressing mechanism is movably mounted at the bottom of the cutting die. Clamping plates are movably mounted on both sides of the bottom of the support frame. An adjustment mechanism is mounted at the bottom of the support frame to adjust the distance between the two clamping plates so that the sound insulation cotton is positioned directly below the cutting die. However, existing sound insulation cotton cutting equipment cannot accurately position the cutting path when dealing with the demand for sound insulation cotton with complex and irregular shapes such as bionic honeycomb structures. Although manual cutting has a certain degree of flexibility, it is extremely inefficient and the accuracy is difficult to guarantee. Cutting errors can easily lead to the sound insulation cotton not being perfectly matched with the irregular space inside the car, reducing the sound insulation effect, wasting materials, and increasing production costs.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was developed based on the existing sound insulation cotton cutting equipment. Summary of the Invention

[0006] The purpose of this invention is to provide a positioning and cutting device for biomimetic honeycomb structure automotive sound insulation cotton, so as to solve the problem mentioned in the background art that it is impossible to position and cut sound insulation cotton with irregular shapes.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A positioning and cutting device for biomimetic honeycomb structure automotive sound insulation cotton includes a work platform, a support frame fixedly mounted on the rear side of the work platform, an operating host fixedly mounted on the upper surface of the support frame, an operating display screen mounted on the front side of the operating host, an operating button mounted below the operating display screen, and a laser cutting blade connected to the operating host via a connecting cable. A cutting table is mounted above the work platform, with limit plates on both sides of the cutting table, and the cutting table has a left-right moving structure. A model frame is mounted at the bottom of the support frame, with limit blocks installed inside the model frame. A fixing plate is fixedly connected to the front side of the model frame, and the laser cutting blade is fixedly mounted on the front end of the fixing plate.

[0009] Preferably, a first servo motor is installed on the left side of the work platform, and a threaded rod is connected to the right output end of the first servo motor, with the right end of the threaded rod rotatably connected to the right side of the inside of the work platform.

[0010] Using the above technical solution, a first servo motor and its connected threaded rod are installed on the left side of the work platform. The first servo motor drives the threaded rod to rotate, which can accurately control the left and right movement of the cutting table, realize the precise positioning of the sound insulation cotton in the horizontal direction, improve the accuracy of cutting, and meet the position adjustment requirements of irregular shape cutting of bionic honeycomb structure sound insulation cotton.

[0011] Preferably, a movable block is fixedly installed at the bottom of the cutting table, and the movable block is threaded to the outside of the threaded rod. A slider is fixedly installed on the front and rear sides of the bottom of the cutting table, and a sliding groove is opened on the front and rear sides of the upper surface of the working platform, and the slider is slidably connected to the inside of the sliding groove.

[0012] By adopting the above technical solution, the moving block at the bottom of the cutting table is threadedly connected to the threaded rod, and the slider is slidably connected to the sliding groove on the working platform. This structural design makes the cutting table more stable during movement, avoiding shaking or deviation, and further ensuring the stability of the sound insulation cotton position during cutting, thereby improving cutting accuracy and reducing cutting errors.

[0013] Preferably, a second servo motor is fixedly installed on the top of the support frame, and the lower output end of the second servo motor is connected to the eccentric position of the limiting block, and the limiting block is circular.

[0014] Using the above technical solution, when the limiting block is circular, the second servo motor at the top of the support frame drives the circular limiting block to rotate eccentrically, which can regularly squeeze and push the sound insulation cotton in the model frame, so that it maintains a certain tension and positional fine adjustment during the cutting process, which helps to cut out a circular biomimetic honeycomb structure and improve the uniformity of cutting and product quality.

[0015] Preferably, a second servo motor is fixedly installed on the top of the support frame, and the lower output end of the second servo motor is connected to the eccentric position of the limiting block, and the limiting block is triangular arc-shaped.

[0016] Using the above technical solution, when the limiting block is triangular arc-shaped, the second servo motor drives the triangular arc-shaped limiting block to rotate eccentrically. Its unique shape can more flexibly adapt to the complex shape requirements of the bionic honeycomb structure sound insulation cotton, and achieve more precise positioning and adjustment of the sound insulation cotton during the cutting process. This helps to cut out a chamfered square bionic honeycomb structure, further improving the cutting accuracy and product adaptability.

[0017] Preferably, the model frame is assembled by splicing left and right sides, and the inner edge of the model frame is provided with a snap-fit ​​groove, and the limiting block is inside the snap-fit ​​groove.

[0018] Using the above technical solution, the model frame is assembled by splicing left and right sides, and the inner edge is opened with a snap-fit ​​groove for installing the limit block, which improves the versatility of the equipment. The snap-fit ​​groove ensures that the limit block is installed firmly and that it can play a normal positioning and adjustment role during operation.

[0019] Preferably, the fixing plate is slidably connected to the middle groove of the crossbar, and the crossbar is horizontally slidably connected to the inside of the support block, and the support block is fixedly installed on the left and right sides of the bottom of the support frame.

[0020] Using the above technical solution, the fixed plate is slidably connected to the crossbar, and the crossbar is horizontally slidably connected to the support block. This multi-layer sliding structure allows the laser cutting blade to have a larger range of movement and greater flexibility in the horizontal direction, enabling it to better follow the irregular contours of the biomimetic honeycomb sound insulation cotton for cutting and improving the equipment's adaptability to cutting complex shapes.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the positioning and cutting equipment for this biomimetic honeycomb structure automotive sound insulation cotton...

[0022] 1. High-precision cutting: The cutting table moves smoothly and precisely through the cooperation of the first servo motor, threaded rod, moving block, slider and sliding groove; at the same time, the second servo motor drives limit blocks of different shapes to position and adjust the sound insulation cotton, ensuring that the bionic honeycomb structure sound insulation cotton can be cut accurately according to the preset path when cutting, which greatly improves the cutting accuracy, reduces the cutting error, and makes the produced sound insulation cotton better fit the car interior space and improve the sound insulation effect.

[0023] 2. High adaptability and versatility: The modular design and snap-fit ​​structure of the model frame facilitate replacement and adjustment to accommodate different specifications of sound insulation cotton.

Example 1

[0031] Please see Figure 1-4 This utility model provides a technical solution:

[0032] A positioning and cutting device for biomimetic honeycomb structure automotive sound insulation cotton includes a working platform 1, a support frame 2 fixedly installed on the rear side of the working platform 1, an operating host 10 fixedly installed on the upper surface of the support frame 2, an operating display screen 11 installed on the front side of the operating host 10, an operating button 12 installed below the operating display screen 11, and a laser cutting blade 13 connected to the operating host 10 via a connecting cable. A cutting table 6 is installed above the working platform 1, and limit plates 9 are installed on the left and right sides of the cutting table 6, forming a left and right moving structure.

A fixing plate 18 is fixedly connected to the front side of the model frame 16, and the laser cutting blade 13 is fixedly installed at the front end of the fixing plate 18.

[0033] A first servo motor 4 is installed on the left side of the work platform 1, and a threaded rod 5 is connected to the right output end of the first servo motor 4. The right end of the threaded rod 5 is rotatably connected to the right side of the inside of the work platform 1. A moving block 7 is fixedly installed on the bottom of the cutting table 6, and the moving block 7 is threadedly connected to the outside of the threaded rod 5. A slider 8 is fixedly installed on the front and rear sides of the bottom of the cutting table 6, and a sliding groove 3 is opened on the front and rear sides of the upper surface of the work platform 1. The slider 8 is slidably connected inside the sliding groove 3. The first servo motor 4 on the left side of the work platform 1 is connected to the threaded rod 5 at the right output end. The first servo motor 4 is the moving support for the cutting table 6. Powered by the threaded rod 5, the rotational motion of the motor is converted into the linear motion of the cutting table 6, which can precisely control the position of the cutting table 6, meeting the positional accuracy requirements of the bionic honeycomb structure automotive sound insulation cotton during cutting and improving the cutting accuracy. The moving block 7 at the bottom of the cutting table 6 is threadedly connected to the threaded rod 5, and the slider 8 is slidably connected to the sliding groove 3 on the working base 1. This structure ensures the stability of the cutting table 6 during movement, avoiding shaking or offset during movement, and ensuring that the sound insulation cotton placed on the cutting table 6 remains stable during cutting, thereby improving the cutting accuracy and quality.

[0034] A second servo motor 14 is fixedly installed on the top of the support frame 2, and the output end of the second servo motor 14 is connected to the eccentric position of the limiting block 15. The limiting block 15 is circular. The model frame 16 is assembled by splicing left and right sides, and a snap-fit ​​groove 17 is opened on the inner edge of the model frame 16.

The support block 20 is fixedly installed on the left and right sides of the bottom of the support frame 2. When the limiting block 15 is circular, the second servo motor 14 at the top of the support frame 2 drives the circular limiting block 15 to rotate eccentrically, which can regularly squeeze and push the sound insulation cotton in the model frame 16, so that it maintains a certain tension and positional fine adjustment during the cutting process, which helps to cut out circular biomimetic honeycomb structures. The structure improves the uniformity of cutting and product quality. The model frame 16 is assembled by splicing left and right sides and has a snap-fit ​​groove 17 on the inside.

Example 2

[0035] Please see Figure 5 This utility model provides a technical solution:

[0036] A second servo motor 14 is fixedly installed on the top of the support frame 2, and the output end of the second servo motor 14 is connected to the eccentric position of the limiting block 15. The limiting block 15 is triangular arc-shaped. When the limiting block 15 is triangular arc-shaped, the second servo motor 14 drives the triangular arc-shaped limiting block 15 to rotate eccentrically. Its unique shape can more flexibly adapt to the complex shape requirements of the bionic honeycomb structure sound insulation cotton, and achieve more precise positioning and adjustment of the sound insulation cotton during the cutting process. This helps to cut out a chamfered square bionic honeycomb structure, further improving the cutting accuracy and product adaptability.

[0037] Working principle:

[0038] In use, the biomimetic honeycomb structure automotive sound insulation cotton is first placed in the model frame 16. The cutting parameters are set using the operation button 12 on the host 10, and the operation display screen 11 can display relevant information in real time. The first servo motor 4 is started, and its output end drives the threaded rod 5 to rotate. The moving block 7, which is threaded to the threaded rod 5, drives the cutting table 6 to move left and right in the sliding groove 3, adjusting the sound insulation cotton to a suitable cutting position. Then, the second servo motor 14 is started, which drives the limiting block 15 to rotate eccentrically. If the limiting block 15 is circular or triangular arc-shaped, it will exert different kinds of squeezing and pushing effects on the sound insulation cotton, so that the sound insulation cotton maintains a suitable tension and position during the cutting process. At the same time, the laser cutting blade 13 moves flexibly along the sliding structure composed of the crossbar 19 and the support block 20 under the drive of the fixed plate 18 according to the program set by the host 10, to precisely cut the sound insulation cotton. During the cutting process, the cutting table 6 can be adjusted again as needed to complete the cutting of the entire biomimetic honeycomb structure sound insulation cotton.
