DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The utility model provides a lens blank separation device, the structure of which is as follows: Figure 1 and Figure 2As shown, it includes a conveying pipe 100, a material dividing mechanism 200 and a self-locking mechanism 300. The conveying pipe 100 is used to convey lens blanks side by side from top to bottom; the material dividing mechanism 200 includes an upper material stopper 210 and a lower material stopper 220, and the upper material stopper 210 and the lower material stopper 220 are both arranged in the conveying pipe 100, and the lens blank can push the upper material stopper 210 and the lower material stopper 220 to move out of the conveying pipe 100; the self-locking mechanism 300 is connected to the lower material stopper 220, and is also used to engage with the upper material stopper 210, so that the upper material stopper 210 located in the conveying pipe 100 is in a locked state, and when the lower material stopper 220 moves out of the conveying pipe 100, the self-locking mechanism 300 is separated from the upper material stopper 210.

[0026] When in use, the upper end of the conveying pipe 100 is connected to the outlet end of the conveying line of the upstream processing step, and the lower end of the conveying pipe 100 is connected to the inlet end of the conveying line of the downstream processing step. The lens blanks enter the conveying pipe 100 in sequence and are transported downward from top to bottom in the conveying pipe 100 in parallel. When it is necessary to separate the lens blanks, the lower material stopper 220 is quickly removed from the conveying pipe 100. When the upper stopper 210 is in the material conveying tube 100, the self-locking mechanism 300 is separated from the upper stopper 210, and the upper stopper 210 is in a free state. At this time, the lens blank located at the bottom layer above the upper stopper 210 moves downward under its own gravity and pushes the upper stopper 210 to quickly move out of the material conveying tube 100 until it passes over the upper stopper 210. Then, the upper stopper 210 is located in the material conveying tube 100 again, and the self-locking mechanism 300 is closed. The upper stopper 210 is engaged with the upper stopper 210 again, and the upper stopper 210 is in a locked state again until the lens blank that has passed the upper stopper 210 reaches the lower stopper 220 and pushes the lower stopper 220 to quickly move out of the material conveying pipe 100, and the self-locking mechanism 300 is separated from the upper stopper 210 again, and the upper stopper 210 is in a free state again, and the material is discharged again, and this cycle is repeated to achieve the separation of the lens blank. In this separation device, the separated lens blank acts as an unlocking key, so that the self-locking mechanism 300 releases the lock of the upper stopper 210, and the lens blank located at the bottom layer above the upper stopper 210 moves downward under the action of its own gravity, pushing the upper stopper 210 to quickly move out of the material conveying pipe 100 and pass over the upper stopper 210, thereby realizing the material separation process. The separation of the lens blank can be completed without relying on electric drive, thereby reducing production costs.

The lower opening 120 is located directly below the upper opening 110, so that one end of the upper material blocking member 210 can extend into the feed pipe 100 along the upper opening 110, and one end of the lower material blocking member 220 can extend into the feed pipe 100 along the lower opening 120.

[0028] As a preferred embodiment, please refer to Figure 2 and Figure 3 The upper material blocking member 210 includes a mounting shaft 211, a plurality of first blocking rods 212 and a chuck 213. The mounting shaft 211 is horizontally rotatably arranged outside the material delivery pipe 100 and close to the upper through port 110. Each of the first blocking rods 212 is circumferentially arranged on the side of the mounting shaft 211. One end of each of the first blocking rods 212 is fixedly connected to one end of the mounting shaft 211. A material distribution groove 2121 is formed between adjacent first blocking rods 212. During the rotation of the mounting shaft 211, each of the first blocking rods 212 The other end of the chuck 213 can enter the feed pipe 100 in sequence along the upper opening 110, and the chuck 213 is coaxially fixedly sleeved on the other end of the installation shaft 211. The chuck 213 is circumferentially provided with a plurality of slots 2131. The installation rod 310 exerts a downward force on the block 320 under the action of its own gravity, so that the block 320 presses against the chuck 213. When the block 320 corresponds to the slot 2131, it is inserted into the slot 2131. At this time, the chuck 213 is in a locked state.

One end of the second blocking rod 221 extends into the material delivery pipe 100 along the lower opening 120. During the downward rotation of one end of the second blocking rod 221, it can be moved out of the material delivery pipe 100. When the lens blank reaches the second blocking rod 221, it will push one end of the second blocking rod 221 to rotate downward, so that one end of the second blocking rod 221 moves out of the material delivery pipe 100.

The block 320 is arranged between the mounting rod 310 and the chuck 213. The upper end of the block 320 is fixedly connected to the middle of the mounting rod 310. The lower end of the block 320 is pressed against the chuck 213 and is used to be inserted into the card slot 2131. The upper end of the connecting rod 330 is hinged to the other end of the installation rod 310, and the lower end of the connecting rod 330 is hinged to the other end of the second blocking rod 221. The installation rod 310 exerts a downward force on the block 320 under its own gravity, so that the block 320 presses against the chuck 213. When the block 320 corresponds to the slot 2131, it is stuck in the slot 2131. At this time, the chuck 213 is in a locked state, and the first blocking rod 212 can block the chuck 213. The lens blank above it falls down, and when the lens blank reaches the second blocking rod 221, the lens blank moves downward under the action of its own gravity and abuts against one end of the second blocking rod 221, so that one end of the second blocking rod 221 rotates downward until one end of the second blocking rod 221 moves out of the feeding pipe 100. At this time, the other end of the second blocking rod 221 rotates upward and pushes the connecting rod 330 to move upward. The connecting rod 330 pushes the other end of the mounting rod 310 to rotate upward, so that the blocking block 320 moves out of the clamping groove 2131, and the chuck 213 is in a free state. The lens blank at the bottom layer above the first blocking rod 212 moves downward under the action of its own gravity and pushes the first blocking rod 212 to rotate downward until the lens blank passes over the first blocking rod 212. At this time, the latter clamping groove 2131 corresponds to the blocking block 320, and the blocking block 320 is clamped into the latter clamping groove 2131, and the chuck 213 is in a locked state again.

[0034] As a preferred embodiment, please refer to Figure 2 The lower end of the card block 320 is a pointed structure, which facilitates the lower end of the card block 320 to move out of the card slot 2131 to avoid interference.

[0035] As a preferred embodiment, please refer to Figure 2The feed pipe 100 includes an upper pipe section 130, a lower pipe section 140, a curved pipe section 150 and a feeding pipe section 160.

The upper opening 110 is opened on the upper pipe section 130, the lower opening 120 is opened on the lower pipe section 140, the curved pipe section 150 is arranged between the upper pipe section 130 and the lower pipe section 140, and the two ends of the curved pipe section 150 are respectively connected to the upper pipe section 130 and the lower pipe section 140. 0 is connected with the upper end of the lower tube section 140, the feeding tube section 160 is arranged above the curved tube section 150, and the lower end of the feeding tube section 160 is connected with the curved tube section 150, so that the lens blanks in the dividing trough 2121 can enter the lower tube section 140 along the curved tube section 150. For the activation of the self-locking mechanism 300, it is necessary to put a lens blank into the feeding tube section 160 as a trigger to avoid manual rotation of the second baffle 221.

[0036] In order to better understand the present invention, the following Figure 1 - Figure 5 The working principle of the technical solution of the utility model is described in detail:

The lens blanks enter the upper tube section 130 in sequence and are conveyed downward from top to bottom in the upper tube section 130 in parallel. Because the mounting rod 310 exerts a downward force on the block 320 under the action of its own gravity, the block 320 presses against the chuck 213. When the block 320 corresponds to the slot 2131, it is inserted into the slot 2131. At this time, the chuck 213 is in a locked state, and the first blocking rod 212 can prevent the lens blank above it from falling. When it is needed When the lens blanks are to be separated, a lens blank is put into the feeding pipe section 160 as a trigger. The put-in lens blank enters the lower pipe section 140 along the curved pipe section 150 and reaches the second baffle rod 221. The lens blank moves downward under the action of its own gravity and abuts against one end of the second baffle rod 221, so that one end of the second baffle rod 221 rotates downward until one end of the second baffle rod 221 moves out of the feeding pipe 100. At this time, the other end of the second baffle rod 221 rotates upward and pushes the connecting rod 330 to move upward.
