Description

Technical Field

[0001] This utility model belongs to the field of structural foam board processing technology, specifically relating to a structural foam irregular part assembly module processing and feeding device. Background Technology

[0002] Structural foam is a foamed material based on plastics and formed by a network of polymers such as aromatic amides. The main types of foams include PVC, PET, and HPE. This type of foam has the characteristics of low density, high strength, and micro-closed cell structure. It is mainly used in the structural core material of wind turbine blades and other fields.

[0003] The existing processing technology for irregularly shaped parts (combined modules) used in wind turbine blades involves lathe-based clamping. Before processing, the dimensions of the blank are measured, and the center of rotation of the blank is calculated based on the dimensions of the end face of the irregularly shaped part. The center point is then manually marked. Two people are needed to lift the blank onto the clamping plate for loading. The centers of both ends of the blank block of the structural foam irregularly shaped part to be processed are clamped and processed. This processing method has problems such as the measurement and calculation of the center of rotation of the blank and the manual marking of the center point, which are prone to deviation. This leads to problems such as the blank being eccentric during the rotation processing of the structural foam irregularly shaped part, insufficient pre-reserved processing allowance, and unqualified products.

[0004] Engraving machines are devices that use programmed code to achieve precise engraving. With the advancement of science and technology, current engraving machines can achieve automated engraving operations. However, existing engraving machines usually require manual placement of the materials to be processed, especially for foam boards. The materials are placed directly under the engraving device and accurately positioned before the engraving operation begins. Because the dimensions of structural foam irregular parts and modules vary, each piece of material needs to be raised and lowered for height positioning. This increases the operation time and cannot guarantee the height positioning accuracy of each board, thus greatly increasing the difficulty of manual material loading and positioning. Furthermore, the horizontality of height positioning cannot be guaranteed, affecting the processing quality of the product and resulting in low production efficiency. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a feeding device for processing irregularly shaped structural foam components into modules. It is equipped with a lifting drive mechanism to drive the lifting screw to move up and down, which can solve the problem of difficulty in positioning the height of the feeding of irregularly shaped structural foam components into modules, and effectively improve the product processing efficiency and quality.

[0006] The technical solution adopted by this utility model is as follows: a feeding device for processing structural foam irregular parts modules, including a support component, which is horizontally installed on the worktable of a carving machine. The top of the support component is used to support the structural foam irregular parts modules to be processed. The bottom of the support component is fixedly provided with sliders at intervals. The support component is installed on the slide rail of the carving machine worktable through the sliders. Lifting screws are vertically provided at both ends of the support component. Lifting drive mechanisms are fixedly provided at both ends of the lower part of the support component and on both sides of the carving machine worktable. The lifting drive mechanisms drive the lifting screws to move the upper part of the support component synchronously up and down through a servo motor and two worm gear reducers. The servo motor is controlled by a PLC automatic control device. The lifting screws on both sides of the support component are commanded to rise or fall simultaneously through the feedback signals from the sensors installed on the carving machine.

[0007] The support assembly includes two long strip support plates, each with a long strip base plate underneath. The two ends of the two base plates are fixedly connected by connecting plates. Slider blocks are fixedly installed at intervals on the bottom of the base plates. The support assembly is slidably connected to the slide rail of the worktable via the sliders at the bottom of the base plates.

[0008] The two support plates are parallel to each other and the upper surfaces of the support plates are on the same horizontal plane.

[0009] The top of the lifting screw is fixedly connected to the bottom of both sides of the support plate. The lifting screw is vertically downward and passes through the center of the worm gear of the first and second worm gear reducers of the lifting drive mechanism. The bottom of the lifting screw is a free end.

[0010] The output shaft of the servo motor is connected to the worm input shaft of the first worm gear reducer, and the worm output shaft of the first worm gear reducer is connected to the worm input shaft of the second worm gear reducer via a coupling.

[0011] Both the first and second worm gear reducers have a ball nut installed at the center of the worm wheel to cooperate with the lifting screw.

[0012] The servo motor and the worm gear reducer are directly connected. To ensure transmission accuracy, both the worm gear reducer and the worm gear reducer are high-precision reducers.

[0013] The support plate is made of hollow aluminum, and an air inlet is provided on the upper surface of the support plate.

[0014] Lifting drive mechanisms are fixedly installed at both ends of the lower part of the support assembly and on both sides of the engraving machine's worktable. The lifting drive mechanisms drive the lifting screws through servo motors and worm gear reducers one and two, causing the upper part of the support assembly to move up and down synchronously. The purpose of this arrangement is that the servo motor is connected to worm gear reducer one, and worm gear reducer one and worm gear reducer two are connected through a coupling. One servo motor drives worm gear reducer one and worm gear reducer two to form a linkage. The forward and reverse rotation of the servo motor is controlled by the PLC program, thereby realizing the lifting and positioning of the support assembly. This ensures that the four lifting screws of the support assembly move synchronously, keeping the upper surfaces of the two support plates on the upper part of the support assembly on the same horizontal plane. This ensures that the processing and loading of the structural foam irregular parts module is in place, effectively guaranteeing the product processing quality.

[0015] The beneficial effects of this utility model are: the feeding device is flexible and convenient to use, runs smoothly, has high precision, is safe and reliable, and has stable performance. It adopts a lifting drive mechanism that uses a servo motor and two worm gear reducers to drive the lifting screws, moving the upper part of the support assembly up and down. A PLC automatic control device controls the servo motor, and the sensors installed on the engraving machine provide feedback signals, instructing the lifting screws on both sides of the support assembly to rise or fall simultaneously. It can meet the lifting and positioning needs of modular feeding and processing of structural foam parts of different lengths and heights, enabling convenient and quick lifting, positioning, and clamping, effectively improving production efficiency and product quality.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-2As shown, a structural foam irregular part assembly module processing and feeding device includes a support component 1, which is horizontally installed on the worktable 31 of the engraving machine 3. The top of the support component 1 is used to support the structural foam irregular part assembly module to be processed. The bottom of the support component 1 is fixedly provided with sliders 14 at intervals. The support component 1 is installed on the slide rail 32 of the worktable 31 of the engraving machine 3 through the sliders 14. The two ends of the support component 1 are vertically provided with lifting screws 25. The two ends of the lower part of the support component 1, located on both sides of the worktable 31 of the engraving machine 3, are fixedly provided with lifting drive mechanisms 2. The lifting drive mechanisms 2 drive the lifting screws 25 to move the upper part of the support component 1 synchronously up and down through servo motors 21 and worm gear reducers 22 and 24. The servo motor 21 is controlled by a PLC automatic control device. The lifting screws 25 on both sides of the support component 1 are instructed to rise or fall simultaneously through the feedback signals from the sensors installed on the engraving machine 3.

[0021] The support assembly 1 includes two long strip support plates 11, each with a long strip base plate 12 below it. The two ends of the two base plates 12 are fixedly connected by connecting plates 12. Slider blocks 14 are fixedly provided at intervals at the bottom of the base plates 12. The support assembly 1 is slidably connected to the slide rail 32 of the worktable 31 through the sliders 14 at the bottom of the base plates 12. This allows the support assembly 1 to slide on the worktable 31 of the engraving machine 3, changing the relative distance between the support assembly 1 and the two end plates of the engraving machine 3 to adapt to the processing needs of structural foam irregular parts modules of different lengths.

[0022] The two support plates 11 are parallel to each other and the upper surfaces of the support plates 11 are on the same horizontal plane, which serves to support and position the foam irregular parts to be processed at the same height.

[0023] The top end of the lifting screw 25 is fixedly connected to the bottom of both sides of the support plate 11. The lifting screw 25 is vertically downward and passes through the center of the worm gear of the first worm gear reducer 22 and the second worm gear reducer 24 of the lifting drive mechanism 2. The bottom end of the lifting screw 25 is a free end.

[0024] The output shaft of the servo motor 21 is connected to the worm input shaft of the worm gear reducer 22, and the worm output shaft of the worm gear reducer 22 is connected to the worm input shaft of the worm gear reducer 24 via a coupling 23.

[0025] Both the first worm gear reducer 22 and the second worm gear reducer 24 have ball nuts installed at the center of the worm wheel to cooperate with the lifting screw 25.

[0026] The servo motor 21 and the worm gear reducer 22 are directly connected. In order to ensure transmission accuracy, both the worm gear reducer 22 and the worm gear reducer 24 are high-precision reducers.

[0027] The support plate 11 is made of hollow aluminum material. An air blowing port 15 is provided on the upper surface of the support plate 11. After the air pipe is connected to high-pressure air, the foam dust can be self-cleaned during the processing.

[0028] In use, the upper part of the worktable 31 of the engraving machine 3 is provided with a gantry frame 33, and the two ends of the worktable 31 of the engraving machine 3 are provided with end plates. Rotary clamps 35 are provided at intervals on the upper part of the end plates, one end of which is a movable end plate 34. The movable end plate 34 can move within the range of 450-1100mm along the slide rail 32 of the worktable 31. Based on the length and height dimensions of the foam composite module blank to be processed, the position of the support assembly 1 on the worktable 31 is adjusted. The foam composite module blank to be processed is placed on the two support plates 11 of the support assembly 1. The servo motor 21 is controlled to rotate forward and backward by the PLC program. The servo motor 21 drives the worm input shaft of the worm gear reducer 1 22 to rotate, and at the same time drives the worm input shaft of the worm gear reducer 24 to rotate. The worm and worm wheel cooperate to drive the worm wheel and the lifting screw 25 passing through it to rotate. The lifting screw 25 drives the two sets of support plates 11 installed on its top to rise or fall simultaneously to adjust the height positioning of the foam composite module blank to be processed. Through the feedback signal of the sensor installed on the engraving machine 3, the PLC automatic control device controls the servo motor 21 and instructs the lifting screw 25 to rise or fall synchronously. The lifting and positioning of the support assembly 1 is controlled to the height specified by the CNC engraving program. One end plate 34 of the engraving machine 3 moves into position along the slide rail 32. The rotating clamps 35, spaced apart on the upper part of both end plates, clamp the structural foam composite module blank to be processed. At this time, the servo motor 21, controlled by the PLC automatic control device, drives the lifting screw 25 and the support plate 11 to descend onto the worktable 31 without affecting the engraving of the structural foam composite module blank. According to the engraving control program, the rotating clamps 35 can rotate 360° around the structural foam composite module blank to be processed. The gantry frame 33 moves along both sides of the worktable 31. The top of the gantry frame 33 is equipped with an engraving tool 36, and the cutting process begins to obtain the structural foam irregular composite module, and the processing is completed. If the dimensions of the foam composite module blank to be processed change, the lifting height of the support component 1 can be adjusted through the PLC program, allowing for quick and stable switching. It is flexible and convenient to use, runs smoothly, has high precision, is safe and reliable, and has stable results. It can meet the lifting and positioning requirements for feeding and processing irregularly shaped foam composite modules of different lengths and heights, and can achieve convenient and quick lifting, positioning, and clamping, effectively improving production efficiency and product quality.
