Description

Technical Field

[0001] The present invention relates to the field of UAV production and processing, and in particular to a device and method for integrally forming a UAV shell. Background Art

[0002] In the production and processing of the drone shell, the injection molding method is generally used. The current process of injection molding the drone shell requires the use of a drone shell mold. After the mold is closed and injection molded, the drone shell can be produced after the injection liquid is formed and demolded.

[0003] However, at present, in the process of injection molding of the drone shell, only the main structural part of the drone shell can be injection molded. The main structural parts of these drone shells are large in volume, so the injection molding path is smooth; but in some small structural parts and complex structural parts of the drone shell, that is, the complex structural parts of the drone shell, in the injection molding path design of the drone shell, such complex structural parts have the disadvantages of being difficult to design the injection molding path, the injection molding path is not smooth, and the injection molding path is narrow. If the main part and the complex structural parts of the drone shell are injection molded at the same stage, it is easy to cause the local structure of the drone shell to be missing after molding, resulting in an increase in the scrap rate.

[0004] At present, in the process of assembling and molding the complex structural parts of the drone shell, the main part and the complex structural part of the drone shell are independently injection molded, and then the complex structural parts are assembled on the main part of the drone shell by gluing, ultrasonic welding and fastener connection methods. However, the current methods have many disadvantages. The gluing and fastener connection methods will lead to an increase in the mass of the drone shell, and the ultrasonic welding method is easy to damage the drone shell. In addition, there are the disadvantages of difficult to control assembly accuracy and complicated assembly operations, and the assembly strength is also insufficient, which can easily lead to frequent failures of the drone shell at this structural part.

[0005] Therefore, it is necessary to develop an integrated molding device and method for a UAV shell to solve the above problems. Summary of the Invention

[0043] like Figure 16-17As shown, it also includes a positioning mechanism 12, which includes an electric push rod 121, a third electric slide rail 122, a scanning camera 123, a sliding sleeve 124 and a stabilizing component 13. The positioning mechanism 12 is located at the upper side of the support frame 2. The positioning mechanism 12 is used to detect the position of the structural parts assembled in the assembly set 114 by visual intelligent recognition, so that the structural parts assembled in the assembly set 114 can be accurately located between the upper mold 73 and the lower mold 51. The electric push rod 121 is fixedly connected to the right side of the upper side of the support frame 2. The electric push rod 121 is a servo drive.

When the electric push rod 121 is controlled to drive the third When the electric slide rail 122 runs to the left, the third electric slide rail 122 first runs stably on the fixed rail 131 through the sleeve 124 until the sleeve 124 cooperates with the fixed rail 131 and the stabilizing rail 132 at the same time. At this time, the scanning camera 123 begins to be located below the upper mold 73. The electric push rod 121 continues to be controlled to run, and the sleeve 124 will be disengaged from the fixed rail 131. At this time, the sleeve 124 will cooperate with the stabilizing rail 132, so that the sleeve 124 can make the scanning camera 123 move stably through cooperation with the stabilizing rail 132.

[0045] Example 2, as Figures 1-17 As shown, the design and processing method of the drone shell and the model and injection molding path of the drone shell integrated molding device of the drone shell is as follows: when designing the drone shell, the main part of the drone shell, that is, the part with a smooth injection molding path, is designed; the structural parts in the drone shell that are difficult to design injection molding paths due to their complex structures, the injection molding paths are not smooth, or the injection molding paths are narrow are separately designed and produced, and the production method of such complex structural parts can be 3D printing; when designing and producing the complex structural parts of the drone shell, combined with the main part of the drone shell and the assembly position of the structural parts, an embedded assembly method is adopted to design a structure in which the structural parts are embedded and assembled in the embedded part of the main part of the drone shell. In addition, a loading structure for the structural part to be assembled at the keyway mounting hole structure of the assembly sleeve 114 is designed. The loading structure between the structural part and the assembly sleeve 114 is designed to be cuttable, so that the loading structure part of the structural part can be cut and removed after the injection molding of the drone shell is completed and hardened. The position of the structural part assembled in the main part of the drone shell, the positional relationship between the structure of the structural part itself and the assembly sleeve 114, and the positional relationship between the structural part and the left end of the mold tube 112 are analyzed and designed. At the same time, a suitable assembly sleeve 114 is selected so that when the mold tube 112 is in the mold hole between the upper mold 73 and the lower mold 51, the part composed of the assembly sleeve 114, the mold tube 112 and the structural part will not affect the injection molding path of the drone shell during injection molding.

[0046] The design method of the upper mold 73 and the lower mold 51 of the drone shell integrated molding device: when designing and producing the mold used for the drone shell integrated molding device, that is, when designing the upper mold 73 and the lower mold 51, the main part and the injection molding path part of the drone shell can be designed first, and the assembly position of the complex structural parts that are difficult to be synchronously injection molded and need to be assembled at a certain place of the drone shell is designed at the drone shell, and the injection molding path is designed in a way that the structural parts are embedded in a shell of the drone, so that when the main part of the drone shell is injected with injection molding liquid, the injection molding liquid can directly cover the embedded part of the structural parts, and wait for the drone to be molded. After the main part of the shell hardens, the embedded part of the structural part will be completely integrated with the main part of the drone shell, achieving the purpose of integrated molding of the drone shell and its structural parts. In addition, the drone shell and its structural parts do not require traditional gluing, ultrasonic welding or fastener connections during the integrated molding process. After the complex structural parts of the drone shell are assembled on the drone shell, the connection strength and accuracy between the structural parts and the main part of the drone shell can be improved, and there is no need for subsequent gluing and fastener connections, which can further control the weight of the drone shell and does not require ultrasonic welding, thereby reducing damage to the main part of the drone shell.

[0047] The assembly process of the integrated molding device for the drone shell is as follows: ① Install the lower mold 51 suitable for injection molding the drone shell on the upper side of the mounting seat 5, and install the upper mold 73 suitable for injection molding the drone shell on the lower side of the fixing seat 72, and adjust the position; ② Install the external injection molding machine and its injection molding pipe on the upper mold 73 and the lower mold 51; ③ Assemble the structural parts suitable for the main part of the drone shell at the assembly sleeve 114, and then install the assembly sleeve 114 on the threaded structure of the mold tube 112 in a threaded fastening manner through the threaded sleeve 113, and then insert the mold tube 112 into the locking ring 101 through the assembly sleeve 114 for positioning, and then start the electrically controlled magnetic suction function of the magnetic clamp 102, so that the magnetic clamp 102 fixes the position of the assembly sleeve 114 and the mold tube 112.

[0048] The injection molding process of the integrated molding device for the UAV shell is as follows: ① Control the first electric slide 81 to drive the connecting frame 82 to move downward, so that the connecting frame 82 drives the mold inlet tube 112, the assembly sleeve 114 and the assembled structural parts to move downward, and at the same time control the second electric slide 83 to drive the mold inlet tube 112 and the assembly sleeve 114 to move to the left, so that the mold inlet tube 112 enters the mold inlet hole structure of the lower mold 51, so that the assembly sleeve 114 and the assembled structural parts are located in the cavity of the injection mold between the upper mold 73 and the lower mold 51; ② Control the second electric slide 83 and the drive motor 94 to make the assembly sleeve 114 move left and right and rotate, so that the position of the structural parts assembled at the assembly sleeve 114 is at the designed position of the structural parts; ③ 4. The external injection molding machine is started to input the injection molding liquid into the injection molding hole structure of the upper mold 73 and the lower mold 51, so that the injection molding liquid is injected into the injection molding hole structure of the upper mold 73 and the lower mold 51, and the injection molding liquid is injected into the injection molding path designed for injection molding. When the main part of the drone shell is input with the injection molding liquid, the injection molding liquid can directly cover the embedded part of the structural part. After the main part of the drone shell is hardened, the embedded part of the structural part It will be completely integrated with the main part of the drone shell to achieve the purpose of embedded assembly structural parts when the drone shell is injection molded. After the injection molding is completed, the external injection molding machine is turned off and the injection molding liquid in the injection molding passage between the upper mold 73 and the lower mold 51 is hardened; ⑤ After the injection molding liquid in the injection molding passage between the upper mold 73 and the lower mold 51 is hardened, the magnetic clamp 102 is controlled to be closed so that the magnetic clamp 102 releases the magnetic fixation of the assembly tube 111, and then the second electric slide rail 83 is controlled to operate so that the second electric slide rail 83 drives the displacement frame 84 to move to the right, and the displacement frame 84 drives the locking ring 101 to move to the right, so that the locking ring 101 is separated from the assembly tube 111; ⑥ The cylinder 71 is controlled to slowly reset and operate so that the upper mold 73 moves upward Slowly separate from the lower mold 51. At this time, the UAV shell formed between the upper mold 73 and the lower mold 51 can be properly straightened to keep the UAV shell in a certain position without large position deviation and collision. The UAV shell formed after demoulding carries the assembly tube 111, the mold tube 112 and the assembly sleeve 114 that are separated from the locking ring 101; ⑦ Operate on the part of the UAV shell assembled with structural parts after molding, cut and remove the cuttable loading structure designed and processed in the structural parts, and then take out the assembly sleeve 114 and the loading structure of the remaining structural parts through the mold tube 112; ⑧ Finally, the UAV shell with complex structural parts assembled in an embedded manner is sent to the next process of deburring and removing the injection molding structure.

[0049] Example 3, as Figures 1-17As shown, a method for integrally forming a UAV shell includes the following steps: S1. Assemble the complex structural parts of the drone shell on the assembly mechanism 11, then install the assembly mechanism 11 on the locking mechanism 10, and control the locking mechanism 10 to fix the position of the assembly mechanism 11; S2. Adjust the position of the structural parts assembled at the assembly mechanism 11 by the pushing mechanism 8 and the reversing mechanism 9, and then position the assembly mechanism 11 on the lower mold 51 by the pushing mechanism 8; S3, controlling the mold clamping mechanism 7 to clamp the upper mold 73 and the lower mold 51, so that the assembly mechanism 11 is sealed and positioned between the upper mold 73 and the lower mold 51; S4. Injection molding is performed in the upper mold 73 and the lower mold 51 to complete the injection molding of the drone shell between the upper mold 73 and the lower mold 51. During the injection molding process of the drone shell, the input injection molding liquid will embed and integrally mold the structural parts assembled at the assembly mechanism 11; S5. Control the locking mechanism 10 to release the position fixation of the assembly mechanism 11, and then use the propulsion mechanism 8 to separate the locking mechanism 10 from the assembly mechanism 11. Then control the mold clamping mechanism 7 to demold the upper mold 73 and the lower mold 51, and finally take out the molded UAV shell.
