period we make the block of holding and pushing the cork base We decide to use the air cylinder and cam structure to push the cork base We also use the limiting pressure valve and throttle valve to adjust the velocity of the cylinder -Phase two: After successful in making the pushing block, we continue to phase two We assembly the shaft with the disk and four clot of holding the cork base We also stick the ratchet and the second disk of malt structure with the disk And one motor is connected with the malt structure to rotate the disk -Phase three: We continue doing the milling part and inserting leather part Two part is separate but they operate synchronous, so we use one motor and two direct gear to drive that two sections at the same time For the milling part, when the machine is operating, this part will move out (in) to the holding cork to milling the cork base so we decide to use the crosshead and slider After that we making the fix stay and stick to the motor • For the inserting part, we use the cylinder to clamp the leather The cylinder is stick to the fix stay In this part we have adjust clamping structure many time to avoid the clamping hurt the leather One optical sensor is stick below the clamping The ratchet is connect to the slider to shift the cork an angle 22.5 degree • - Phase four: We design the control circuit We using the proteus software to draw the schematic circuit and Code vision software to program for the AT Mega controller After completely the control circuit, we try to run the motor And then we use the motor to adjust all mechanical part Finally, we connect all mechanical part to control circuit and test the holding process of machine Below is some picture about our product after finishing 60 61 Figure 5.1: Some picture about final product 62 CHAPTER VI: CONCLUSION 5.1 Result The thesis accomplish most of the proposed problems: • • • • • • Understanding the power transmission of some mechanism system like bevel gear, malt structure, Cam mechanism Calculate and choose the stepping motor for each drive mechanism Calculate and design the pneumatic cylinder Successful in build the Badminton Equipment feather planting machine for manufacturing Badminton shuttlecock Build the control system of machine using Atmega Know how to solve the difficult mechanical problems encountering 5.2 Limitation This is the first time we design the real product so we have a lack of experience Besides some part of this machine we made by ourselves so there are some mistakes during making process The limitation can be summary as follow: Because we use the stepping motor so when the machine is operating it generates some noise and the stepping motor has high energy consuming The inserting leather part are made by ourselves so it’s quite unstable leading to the slow operating of machine and therefore the productivity is slightly lower than expected 5.3 Conclusion When received this thesis, we have determined it is important to assess the full knowledge that we had learned, with main purpose: Design and make the Badminton Equipment feather planting machine for manufacturing Badminton shuttlecock This subject is very suitable for Mechatronics student because it requires us to utilize all knowledge about mechanic, electronics as well as programming After months of study and research reference material with a sense of personal effort, special thanks the instruction of Ph.D Truong Hoanh Son, Dr Nguyen Trong Thanh and from our friends we have completed the work assigned up to date During the process of working, because of lacking of professional knowledge, practical experience and time constraints of the project so we cannot avoid mistakes In near future we will complete some aspect we encountered and try to make some innovation in Badminton shuttlecock 63 manufacturing machine … After doing this project, we see the powerful of Badminton manufacturing machine and the useful application of microprocessor It plays a importance role to control automatically the holding process of making the badminton shuttlecock The microprocessor brings high performance in space, time, economic value and very convenient for using to suit to the development of society In addition the microprocessor can be programmed for many other industrial automation process control REFERRENCES 64 [1] Nguyễn Trọng
