Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail;

Fig. 1 is the overall top view of the utility model;

Fig. 2 is a partial front view of the utility model.

Detailed ways

As shown in Fig. 1 or Fig. 2, the utility model comprises at least one grinding machine platform 1, and there is a clamp for fixing the lens on the grinding machine platform 1; The described grinding device also includes a material transfer mechanism, and the material transfer mechanism includes a station Table 2 and gripper placement frame 3. The station table 2 is equipped with a SCARA robot 4, a raw material loading frame 5 and a finished product discharging frame 6. The raw material feeding frame 5 is used to place lenses to be polished, and the finished product discharging frame 6 It is used to place polished lenses; the bottom of the output rod of the SCARA robot 4 is fixed with a rotating gripper 7, one end of the rotating gripper 7 is provided with a feeding suction cup 8, and the other end of the rotating gripper 7 is provided with a discharge suction cup 9. The middle part of the rotating gripper 7 is provided with an industrial vision system 10 for identifying the position of the lens, and the industrial vision system 10 is electrically connected with the SCARA robot 4; A plurality of suction cups 12 for taking paper are arranged at intervals in sequence around the hand 11 .

The work table 2 is respectively provided with positioning frames 12 for nesting and fixing the raw material feeding frame 5 and the finished product discharging frame 6, and one side of the positioning frame 12 is open.

The middle part of the paper separator grip 11 is fitted with the grip placement frame 3 through a pin hole.

The raw material feeding frame 5 and the finished product discharging frame 6 are respectively arranged on both sides of the SCARA robot 4 .

In this embodiment, there are two grinding machines 1, and the SCARA robot 4 alternately realizes loading and unloading for the two grinding machines 1, which greatly improves the production efficiency. In addition, the SCARA robot is Zhongweixing AR7520 robot.

The working principle of the utility model (take the loading and unloading of one of the grinding machine 1 as an example): the SCARA robot 4 drives the rotating gripper 7 to move above the raw material feeding frame 5, and the industrial vision system 10 recognizes the raw material feeding frame 5 The position of the middle lens, after identifying the position of the lens, the SCARA robot 4 drives the rotating gripper 7 to move to the designated position and then descends, the feeding suction cup 8 grabs the lens, and then the SCARA robot 4 drives the rotating gripper 7 to move to the side of the grinding machine 1, The rotating gripper 7 descends after rotating in the direction of rotation, and the discharge suction cup 9 takes out the ground lens, then rotates the gripper 7 in the direction of rotation and then descends, and the feeding suction cup 8 puts the lens to be polished on it into the fixture of the grinding machine 1 In the middle, the fixture automatically clamps the lens and starts grinding work; finally, the SCARA robot 4 drives the rotating gripper 7 to move to the top of the finished product discharge frame 6, and the discharge suction cup 9 transfers the ground lens to the finished product discharge frame 6, repeating the above steps work process;

Whenever a layer of lenses in the raw material feeding frame 5 is taken, the SCARA robot 4 drives the rotating gripper 7 to grab the paper separator gripper 11 on the gripper placement frame 3 (through the feeding suction cup 8 and the discharging suction cup 9 Simultaneously suck the separator paper gripper 11), the SCARA robot 4 drives the separator paper gripper 11 to grab the interlayer paper and protective tissue paper in the raw material feeding frame 5 and transfer them to the finished product discharge frame 6; the interlayer paper and protective tissue paper After the tissue paper transfer is completed, the SCARA robot 4 puts the paper separator gripper 11 back on the gripper placement frame 3 .
