[0003] Among them, during manual typesetting, employees use handheld vacuum pens to grab the spacers one by one. Some models of spacers need to use magnifying glasses and microscopes to distinguish and adjust product features and front and back. 1. The efficiency is low. Employees can only place about 12,000 pieces using vacuum suction for 12 hours; 2. The product is special (diameter 2.0-12.0mm, thickness about 0.02mm), the product is light and thin, and it is necessary to distinguish the direction or front and back, which is not easy to pick and place, making manual placement difficult; 3. Manual placement may result in errors such as incorrect angles or wrong front and back placement, which requires rework.

[0005] (1) Since the position and orientation of the spacers on the material plate are fixed, each time the corresponding spacers are taken out (such as the spacers facing up), the number of corresponding spacers will be reduced until they are all taken out, and the remaining spacers that do not meet the position conditions cannot be taken out.

[0006] (2) After the spacers are grabbed, they are placed in the tray. In the next process, the spacers need to be taken out from the tray again, which adds an extra Summary of the Invention

DETAILED DESCRIPTION

[0048] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0049] like Figure 1 and 2As shown, the present invention includes a feeding mechanism 100, a turning mechanism 200, a first visual unit 300, a pick-up and discharge mechanism 400, and a transfer mechanism 500. The feeding mechanism 100 is a vibrating plate, which vibrates to transport the separator to the working surface of the turning mechanism 200; the turning mechanism 200 is a flexible vibrating plate, which vibrates to turn the separator on the working surface; the first visual unit 300 is a CCD camera, which can capture the separator image on the working surface and control the pick-up and discharge mechanism 400 to grab the separator and the feeding mechanism 100 to feed the separator based on the separator information analyzed in the separator image. Specifically, the pick-up and discharge mechanism 400 can grab the separator according to the separator coordinates set in the separator image facing upward. When the separator displayed in the separator image is lower than the set value, the feeding mechanism 100 transports the separator to the working platform of the turning mechanism 200. The specific separator image recognition and related intelligent control are existing mature technologies and will not be described in detail here.

[0050] like Figure 4 and Figure 5 As shown, the material taking and unloading mechanism 400 includes a fixed base 401, a first horizontal sliding device 402, a second horizontal sliding device 403, a lifting device 404 and a gripping device 405. The lifting device 404 is mounted on the fixed base 401, and the gripping device 405 is mounted at the bottom of the lifting device 404. The lifting device 404 here usually adopts a cylinder or a hydraulic cylinder, while the gripping device 405 usually adopts a vacuum suction cup; the fixed base 401 is slidably mounted on the first horizontal sliding device 402 and can move horizontally along the length direction of the first horizontal sliding device 402. The first horizontal sliding device 402 is slidably mounted on the second horizontal sliding device 403 as a whole and can move horizontally along the length direction of the second horizontal sliding device 403. The first horizontal sliding device 402 and the second horizontal sliding device 403 are both composed of a fixed bracket, a sliding rail and a sliding block. The sliding block is driven by a cylinder or a linear motor to move linearly.

[0051] like Figure 3As shown, the transfer mechanism 500 of the present invention includes a first transfer table 501, a first conveying track 502, a second conveying track 503, and a second transfer table 504. The first conveying track 502 and the second conveying track 503 are arranged in parallel, and the first transfer table 501 and the second transfer table 504 are respectively arranged on the first conveying track 502 and the second conveying track 503. The transfer mechanism 500 is provided with a first waiting station and a second waiting station. When the first transfer table 501 or the second transfer table 504 is located at the first waiting station, the material taking and placing mechanism 400 moves to the first waiting station and places the separator on the first waiting station. When the first transfer table 501 or the second transfer table 504 is located at the first waiting station, the material taking and placing mechanism 400 moves to the first waiting station and places the separator on the first waiting station. When the first transfer table 501 is at the second waiting position, the material taking device in the next process takes the upper separator from the first transfer table 501 or the second transfer table 504. When the first transfer table 501 is along the first conveying track 502, the first conveying track 502 has two travel points. At these two travel points, the areas of the first transfer table 501 for placing separators are respectively located at the first waiting position and the second waiting position (the first waiting position and the second waiting position can be set to coincide with the first conveying track 502 at these two travel points, or can be set to coincide with the first conveying track 502 at these two travel points). The second transfer platform 504 is provided with a second transfer seat 505 and a second material loading plate 506. The second transfer seat 505 is driven by a second driving device (cylinder or linear motor) to move along the second conveying track 503. When the second transfer seat 505 moves to a position flush with the first waiting station or the second waiting station, the third driving device (the third driving device is usually a cylinder) drives the second material loading plate 506 to move in a vertical direction along the second conveying track 503, thereby making the second material loading plate 506 Located at the first waiting station or the second waiting station, the first transfer table 501 and the second transfer table 504 here alternately move at the first waiting station and the second waiting station in turn (that is, when the first transfer table 501 is located at the first waiting station, the second loading plate 506 on the second transfer table 504 is located at the second waiting station; conversely, when the second loading plate 506 on the second transfer table 504 is located at the first waiting station, the first transfer table 501 is located at the second waiting station). In this way, there is no need to stop the machine, and the production efficiency is doubled.

[0052] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and are not to be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will readily conceive of other specific embodiments of the present invention without inventive effort, and such embodiments will fall within the scope of protection of the present invention.
