Description

Technical Field

[0001] This invention mainly relates to the technical field of skeleton splicing, specifically a multi-material splicing structure for skeletons and its splicing method. Background Technology

[0002] Multi-material splicing of the skeleton is used to create a skeleton structure made of multiple different materials. It can select the most suitable material combination according to specific needs and application scenarios. While maintaining the lightweight of the skeleton, it can make full use of the advantages of various raw materials to improve the strength, stiffness and impact resistance of the skeleton, thereby achieving performance indicators such as lightweight, high strength and high stiffness.

[0003] Multi-material splicing of a skeleton involves connecting two or more materials together to form a sturdy structure while retaining the unique properties of each material. The splicing of thermosetting plastics involves the interaction between molecules, which generates a certain degree of internal friction between them. This friction allows them to be tightly bonded together.

[0004] When positioning the skeleton before splicing, conventional fixing equipment is difficult to meet the usage requirements. Displacement is prone to occur during the splicing process, causing the skeleton to shift during the thermosetting process. Since the angle adjustment remains unchanged, it is difficult to guarantee the efficiency and quality of splicing multiple materials of the skeleton, and it is difficult to meet the usage requirements.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of the present invention will now be described. Example

[0020] Please see the appendix Figure 1-6 As shown, a multi-material splicing structure for a skeleton includes a main skeleton, a splicing platform, a multi-material splicing feeding device located on the splicing platform, and a fixing device for splicing and fixing the main skeleton. The multi-material splicing feeding device includes multiple feeding barrels, each feeding barrel is equipped with a feeding and unblocking component, and each feeding barrel's outlet is connected to a splicing pressing device. The splicing pressure of the splicing pressing device is matched with the properties of the materials inside it.

[0021] It should be noted that this application is easy to operate, ensuring the efficiency of multi-material splicing of the skeleton. By setting up a feeding and unblocking component, it reduces downtime caused by material jamming and ensures the integrity of the splicing. Furthermore, by setting up multiple feeding and pressing equipment, it is no longer necessary to adjust the heating and pressing pressure back and forth according to the material, and different materials can be spliced ​​in a streamlined operation, thereby improving the efficiency of multi-material splicing of the skeleton. Furthermore, the main frame is equipped with a fixing device to facilitate the fixing of the frame to be spliced. The fixing device has multiple fixing methods and can be fixed according to the frame structure. After fixing, the position and angle of the main frame can be adjusted according to the structure and position of the mold to be pressed, so that the position of the main frame to be spliced ​​corresponds to the position of the material splicing mold, thereby improving the splicing efficiency.

[0022] Please see the appendix Figure 2 , 3As shown in Figures 5 and 6, the fixing equipment is located on one side of each splicing molding equipment. The fixing equipment includes a fixing platform 1. The top of both sides of the fixing platform 1 is symmetrically provided with first grooves 11. The fixing platform 1 is provided with moving components 41 near the two shorter sides. The moving components 41 are provided with multi-angle adjustment components 42. The multi-angle adjustment components 42 are provided with placement limiting components 43 for placing the main frame. Each moving component 41 includes a moving screw 411, a limiting slide rail 412, a fixing plate 413 and a drive motor 415. The moving screw 411 is located inside the first groove 11. Fixed bearing seats 414 are embedded in the two ends of the first groove 11. 1. Both ends are connected to the fixed bearing seat 414. The limiting slide rail 412 is located near the top of the two longer edges of the fixed platform 1. A sliding block 416 is connected through the moving screw 411. The top of the sliding block 416 is fixed to the bottom of the fixed plate 413. Sliding blocks 417 are connected to the bottom of both sides of the fixed plate 413. The sliding blocks 417 are slidably connected to the limiting slide rail 412. The drive motor 415 is located at the end of the fixed platform 1. One end of the moving screw 411 passes through the fixed bearing seat 414 and is connected to the output end of the drive motor 415 through a coupling. Sliding grooves 4131 are symmetrically and parallelly arranged on the fixed plate 413. The multi-angle adjustment component 42 is located on the fixed plate 413.

[0023] It should be noted that in this embodiment, the movable component 41 facilitates the front-back and left-right adjustment of the position between the main frame and the molding equipment, making operation convenient. When left-right adjustment is required, the drive motor 415 is started, and the drive motor 415 drives the movable lead screw 411 to rotate. While the movable lead screw 411 rotates, it drives the sliding block 416 to move. The top of the sliding block 416 is fixed to the fixed plate 413, and the two sides of the fixed plate 413 slide with the limiting slide rail 412 through the sliding block 417, so that the fixed plate 413 can be adjusted left and right, making adjustment convenient. When it is necessary to adjust the position between the main frame and the molding equipment, push the sliding plate 421. The bottom of the sliding plate 421 slides inside the sliding groove 4131 on the top of the fixed plate 413. The operation is simple and makes the position of the main frame to be spliced ​​correspond to the position of the material splicing molding, thus improving the splicing efficiency.

[0024] Please see the appendix Figure 3 and 4As shown, the multi-angle adjustment assembly 42 includes a sliding plate 421 and a position adjustment plate 422. The sliding plate 421 is parallel to the fixed plate 413. The bottom of the sliding plate 421 slides inside the sliding groove 4131. The position adjustment plate 422 is located on the sliding plate 421. The bottom of the position adjustment plate 422 is rotatably connected to the top of the sliding plate 421 via a rotating shaft. Multiple position adjustment limit screws 4222 are provided through the top of the position adjustment plate 422. A placement groove 4221 is provided on the top of the position adjustment plate 422 to place the limit assembly. The component 43 is located inside the placement groove 4221, which has an internally concave arc-shaped structure. The placement limiting component 43 includes a limiting airbag 431 located inside the placement groove 4221 near both ends and a limiting block 432 located on both sides of the middle of the placement groove 4221. The limiting airbag 431 is connected to an external air supply device through a high-pressure air pipe. The limiting block 432 slides on the inner wall of both sides of the middle of the placement groove 4221. A limiting spring 433 is provided on the side of the limiting block 432 away from the placement groove 4221.

[0025] It should be noted that in this embodiment, the main frame is equipped with a fixing device to facilitate the fixing of the frame to be spliced. The fixing device has multiple fixing methods and can be fixed according to the frame structure. After fixing, the position and angle of the main frame are adjusted according to the structure and position of the mold to be pressed, so that the position of the main frame to be spliced ​​corresponds to the position of the material splicing mold, thereby improving the splicing efficiency. Place the main frame into the placement slot 4221 on the position adjustment plate 422. Determine whether the main frame is placed in the middle or at the end of the placement slot 4221 based on its structure. Press the main frame down, and the main frame will move the limiting block 432 to both sides, compressing the limiting spring 433. The main frame will then engage in the placement slot 4221. The elastic pressure of the limiting spring 433 will compress the limiting block 432 to limit and fix the main frame. Activate the limiting airbag 431 and inflate it. The expanding airbag will limit and compress the main frame on both sides. With multiple fixing methods using the limiting block 432 and the limiting airbag 431, the system is flexible and can be fixed according to the structure of the main frame.

[0026] The feeding and unblocking assembly includes a telescopic rod, an unblocking rod, an electromagnet, a squeezing block, and a lifting airbag. The unblocking rod has an I-shaped structure that tapers towards the bottom. The lifting airbag is fitted onto the outer circumferential wall of the middle part of the unblocking rod. The electromagnet is fixedly located on the outer wall of the unblocking rod at the top of the lifting airbag. A limit block is provided on the outer wall of the unblocking rod below the lifting airbag, and the limit block is fixedly connected to the unblocking rod. The squeezing block is slidably fitted onto the outer wall of the unblocking rod between the lifting airbag and the limit block. The top of the unblocking rod is fixed to the bottom of the output end of the telescopic rod, and the telescopic rod is fixed to the top of the feeding hopper. The top of the lifting airbag is connected to an external air supply device through a high-pressure air pipe that runs through the inside of the unblocking rod.

[0027] It should be noted that in this embodiment, by setting up a material feeding and unblocking component, the downtime caused by material jamming is reduced, the integrity of the splicing is ensured, and the problem of insufficient material in the splicing is prevented due to material jamming. When feeding and conveying materials, the telescopic rod is activated, which drives the unblocking rod to move up and down. When the telescopic rod extends and drives the unblocking rod downward, the airbag is de-energized, the electromagnet is de-energized, and the squeezing block is reset, thus unblocking the material downward. During the downward unblocking process, the unblocking rod squeezes the material, and the squeezing force of the unblocking rod itself may cause material to get stuck. When the telescopic rod moves the unblocking rod upward, the lifting airbag inflates, the electromagnet is energized, and the electromagnet attracts the extrusion block. The extrusion block compresses the lifting airbag, causing it to deform upward. As the telescopic rod moves the unblocking rod upward, it also causes the material to move downward. At this time, the area where the unblocking rod moves has space, and the material is released through this space, reducing downtime caused by material jamming, ensuring the integrity of the splice, and preventing material shortages in the splice due to jamming.

[0028] Please see Figure 1-6 As shown in the above embodiments, a method for splicing a multi-material splicing structure of a skeleton will also be provided, including the following steps: Step 1: Splicing and Fixing. Place the main frame to be spliced ​​on the fixing device and adjust and fix the angle. Place the main frame in the placement slot 4221 on the position adjustment plate 422. Determine whether the main frame is placed in the middle or at the end of the placement slot 4221 according to its structure. Press down on the main frame. The main frame squeezes the limiting block 432 to move to both sides and compresses the limiting spring 433. The main frame is locked in the placement slot 4221. The elastic pressure of the limiting spring 433 squeezes the limiting block 432 to limit and fix the main frame. Activate the limiting airbag 431 and inflate it. The limiting airbag 431 expands and limits and compresses the main frame on both sides. Step 2, splicing angle adjustment: Adjust the position angle of the main frame according to the position to be spliced. When adjusting, rotate the position adjustment plate 422 so that the position to be spliced ​​of the main frame corresponds to the position of the material splicing mold. After the adjustment is completed, fix the position adjustment plate 422 by the position adjustment limit screw 4222 and start the moving component 41 so that the position to be spliced ​​of the main frame is placed at the material splicing mold. Step 3: Assemble the mold. Start the molding equipment to assemble the molds. After completion, repeat the next process. Example

[0029] Multi-material splicing of the skeleton involves connecting two or more materials together to form a sturdy structure while retaining the unique properties of each material. The splicing of thermosetting plastics involves the interaction between molecules, which generates a certain degree of internal friction between them. This friction allows them to be tightly bonded together. Before splicing, the main frame to be spliced ​​is placed on the fixing equipment and the angle is adjusted and fixed. The main frame is placed in the placement groove 4221 on the position adjustment plate 422. According to the structure of the main frame, it is determined whether the main frame is placed in the middle or end of the placement groove 4221. The main frame is pressed down, and the main frame squeezes the limiting block 432 to move to both sides to compress the limiting spring 433. The main frame is locked in the placement groove 4221. The elastic pressure of the limiting spring 433 squeezes the limiting block 432 to limit and fix the main frame. The limiting airbag 431 is activated and inflated. The limiting airbag 431 expands to limit and compress and fix the main frame on both sides. The splicing angle is adjusted according to the position of the main frame to be spliced. During adjustment, the position adjustment plate 422 is rotated so that the position of the main frame to be spliced ​​corresponds to the position of the material splicing mold. After adjustment, the position adjustment plate 422 is fixed by the position adjustment limit screw 4222. The moving component 41 is started so that the position of the main frame to be spliced ​​is placed in the material splicing mold. Before the formal splicing, the thermosetting plastic sheet is pre-treated. The pre-treated thermosetting material is placed in the heating press, and an appropriate heating time and temperature are set. After the set temperature is reached, a certain pressure is applied to make it tightly bonded. Thermosetting splicing of the frame has many advantages, such as high strength, good rigidity, wear resistance, high temperature resistance, and not easy to age.

[0030] The working principle of this invention is as follows: Start the preheating equipment for splicing molding. Place the main frame to be spliced ​​on the fixing equipment and adjust and fix its angle. Place the main frame in the placement groove 4221 on the position adjustment plate 422. Determine whether the main frame is placed in the middle or at the end of the placement groove 4221 based on its structure. Press down on the main frame. The main frame compression limiting block 432 moves to both sides, compressing the limiting spring 433. The main frame engages in the placement groove 4221. The elastic pressure of the limiting spring 433 compresses the limiting block 432 to limit and fix the main frame. Activate the limiting airbag 431 and inflate it. The expanding airbag 431 limits and compresses the sides of the main frame. Adjust the position and angle of the main frame according to the splicing position. During adjustment, rotate the position adjustment plate 422 to align the splicing position of the main frame with the position of the material splicing molding. After adjustment, fix the position adjustment plate 422 with the position adjustment limiting screw 4222. Activate the moving component 41. The drive motor 415 is started, which drives the moving screw 411 to rotate. As the moving screw 411 rotates, it drives the sliding block 416 to move. The top of the sliding block 416 is fixed to the fixed plate 413. The two sides of the fixed plate 413 slide with the limiting slide rail 412 through the sliding block 417, so that the fixed plate 413 can be adjusted left and right. When it is necessary to adjust the position between the main frame and the molding equipment, the sliding plate 421 is pushed. The bottom of the sliding plate 421 slides inside the sliding groove 4131 at the top of the fixed plate 413. The operation is simple. The position of the main frame to be spliced ​​corresponds to the position of the material splicing molding. The position is adjusted back and forth so that the position of the main frame to be spliced ​​is placed at the material splicing molding. Before the formal splicing, the thermosetting plastic sheet is pre-treated. The pre-treated thermosetting material is placed in the heating press, and an appropriate heating time and temperature are set. After the set temperature is reached, a certain pressure is applied to make it tightly bonded. The molding equipment is started to perform molding splicing. After completion, the next process is repeated.
