Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-3 , an embodiment provided by the utility model:
[0019] A wax bonding mechanism for contact lens processing comprises a base 1, an extension column 9 and a contact lens buckle 10, the top of the base 1 is fixedly connected to a limit box 2, the interior of the limit box 2 is fixedly connected to a motor 3, the top of the output shaft of the motor 3 is fixedly connected to a threaded rod 4, the external thread of the threaded rod 4 is connected to a lifting block 5, the bottom of the lifting block 5 is fixedly connected to a first pneumatic clamping seat 7, and the top of the base 1 is fixedly connected to a second pneumatic clamping seat 8.
[0020] Furthermore, the output shaft of the motor 3 is fixedly connected to the threaded rod 4, so that after the motor 3 is started, it can drive the threaded rod 4 to rotate. The threaded rod 4 is threadedly connected to the lifting block 5, and the lifting block 5 is slidably connected to the limit box 2 through the limit groove 201, so that when the threaded rod 4 rotates, it can drive the lifting block 5 to move up and down. The limit rod 6 penetrates the lifting block 5 and is slidably connected to the lifting block 5 to maintain the stability of the lifting block 5 during the up and down movement.
[0021] Furthermore, the lifting block 5 is fixedly connected to the first pneumatic clamping seat 7, so that when the lifting block 5 moves, it can drive the first pneumatic clamping seat 7 to move synchronously. The first pneumatic clamping seat 7 and the second pneumatic clamping seat 8 can clamp the extension column 9 and the contact lens buckle 10 respectively.
[0022] Furthermore, the pneumatic guide rail 11 drives the movable plate 12 to move left and right. The movable plate 12 is fixedly connected to the support block 13, so that when the movable plate 12 moves, it can drive the support block 13 to move synchronously. The support block 13 is fixedly connected to the pumping wax coating machine 14, so that when the support block 13 moves, it can drive the pumping wax coating machine 14 to move synchronously.
[0023] Furthermore, the wax pumping machine 14 is used to apply wax to the contact lens buckle material 10 on the second pneumatic clamping seat 8, the delivery hose 15 is used to deliver liquid wax, and the wax liquid storage tank 16 is used to store liquid wax.
[0024] Working principle: Place the extension column 9 and the contact lens buckle 10 on the first pneumatic clamping seat 7 and the second pneumatic clamping seat 8 respectively, start the first pneumatic clamping seat 7 and the second pneumatic clamping seat 8, clamp the extension column 9 and the contact lens buckle 10 respectively, start the pneumatic guide rail 11 to move the movable plate 12, the support block 13 and the pumping wax coating machine 14 to the right, so that the pumping wax coating machine 14 corresponds to the extension column 9 on the second pneumatic clamping seat 8, start the pumping wax coating machine 14, and the pumping wax coating machine 14 will apply the liquid wax in the storage tank 16 to the contact lens buckle 10 of the second pneumatic clamping seat 8, the motor 3 drives the threaded rod 4 to rotate, and the threaded rod 4 drives the lifting The block 5 and the first pneumatic clamping seat 7 move downward, so that the extension column 9 contacts the liquid wax on the contact lens buckle 10. After the liquid wax cools and solidifies, the extension column 9 and the contact lens buckle 10 are bonded together, and the first pneumatic clamping seat 7 and the second pneumatic clamping seat 8 are closed. The motor 3 drives the threaded rod 4 to reverse, so that the lifting block 5 and the first pneumatic clamping seat 7 move upward, and the extension column 9 and the contact lens buckle 10 bonded to each other are taken out from the second pneumatic clamping seat 8. The bonding of the extension column 9 and the contact lens buckle 10 can increase the length of the contact lens buckle 10 in a variable manner, so that the contact lens buckle 10 is clamped by the extension column 9 during the subsequent cutting process.
