[0002] With the advancement of science and technology, the integrated circuit industry has sprung up like mushrooms after rain. Automated production lines manufacture integrated circuit products. During the operation, Fig.10 As shown in FIG. 1 , a schematic diagram of the entire integrated circuit is shown, and a single product 20 needs to be removed from the frame 19. Therefore, as Fig.11 As shown, the product needs to be removed from the frame 19 by the first suction nozzle 21, and the product needs to be placed on the opening and closing platform 23, and then the product needs to be placed on the tray 24 by the second suction nozzle 22 for the next processing. However, the spacing between the products 20 on the frame 19 is different from the spacing of the tray 24. The spacing between each product 20 on the frame 19 is 1.1mm, but the product spacing on the tray 24 is 2.2mm, and the spacing between the suction nozzles is inconvenient to adjust. Therefore, two sets of suction nozzles need to be set, and at the same time, they need to be converted through the opening and closing platform 23 that can adjust the spacing to meet the needs of product loading. Moreover, the current opening and closing platform is a combination of a cylinder and a spring. The cylinder is used for closing and the spring is used for opening. With such a structure, when closing, it is necessary to adjust the cylinder flow rate to control the closing speed, and when opening, the spring is directly opened. It is easy to cause uneven opening and closing speeds, causing product jumping and causing product warping. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0026] Example 1

[0027] See also Figure 1-9 A stable controllable position opening and closing platform comprises a carrying plate 1, a servo motor 2 is arranged under the carrying plate 1, two limit plates 3 are connected to the top surface of the carrying plate 1, an opening and closing control plate 4 is arranged between the two limit plates 3, a swing rod 5 is connected to the transmission shaft of the servo motor 2, an end of the swing rod 5 away from the servo motor is connected to a shaft rod 6, a circular hole 15 is opened on the carrying plate 1 between the two limit plates, the swing rod 5 is movably arranged in the circular hole 15, and the shaft rod 6 is connected to the opening and closing control plate 4. When the servo motor 2 works, it drives the swing rod 5 to rotate, which can drive the opening and closing control plate 4 to swing.

[0028] The top surface of the opening and closing control plate 4 is provided with two rows of waist-shaped grooves 7, and the spacing between the waist-shaped grooves 7 in each row is equal. The two rows of waist-shaped grooves 7 are aligned one by one, wherein the waist-shaped groove 7 in the middle is arranged vertically, and the waist-shaped grooves 7 on both sides are inclined away from the waist-shaped groove in the middle, and the inclination angles are the same; the two limit plates 3 are provided with opposite notches 8, and the notches 8 correspond to the waist-shaped grooves 7 one by one, and the width of the notches 8 gradually increases from the middle to the two sides, and the opening and closing plates 9 are arranged on the two opposite notches 8, and the end of the middle opening and closing plate 9 is tightly attached to the corresponding notch 8, so that the middle opening and closing plate 9 can be opened. The closing plate 9 remains fixed, and the ends of the other opening and closing plates 9 are movably arranged in the corresponding notches 8. Slide rods 10 are connected to the two sides of the bottom surface of the opening and closing plates 9. Rotary bearings are rotatably connected to the slide rods 10. The two slide rods 10 are respectively slidably arranged in the corresponding two waist-shaped grooves 7 through the rotary bearings. When the opening and closing control plate 4 swings, the waist-shaped grooves 7 and the slide rods 10 cooperate to drive the opening and closing plates 9 to close or separate, and the slide rods 10 contact with the waist-shaped grooves 7 through the rotary bearings to avoid wear of the structural parts when the opening and closing control plate 4 reciprocates.

[0029] In this embodiment, two fixing blocks 11 are connected between the two limit plates 3, two guide rods 12 are connected to the two fixing blocks 11, and all the opening and closing plates 9 are slidably connected to the guide rods 12. The opening and closing plates 9 slide along the guide rods 12 to prevent the opening and closing plates from shifting during the opening and closing process.

[0030] In this embodiment, a positioning portion for positioning the product is provided on the top surface of the opening and closing plate 9, and the positioning portion includes a rectangular frame 13 connected to the opening and closing plate 9 and a plurality of rectangularly arranged protrusions 14 provided on the periphery of the rectangular frame. When the product is separated from the frame, the product is placed in the rectangular frame 13 through the suction nozzle to position the product and prevent the product from shifting.

[0031] In this embodiment, the servo motor 2 is connected to a mounting block 16, and mounting holes are provided on the mounting block 16 and the carrier plate 1. The servo motor 2 can be fixed at a desired position through the mounting holes on the mounting block 16, and the carrier plate 1 can be fixed at a desired position through the mounting holes on the carrier plate 1.

[0032] The working principle of this embodiment is as follows: the product on the frame 19 is adsorbed by the first suction nozzle 21, and then placed in the positioning part of the opening and closing plate 9, and then the servo motor 2 is controlled to work to drive the swing rod 5 to rotate. Since the two ends of the middle opening and closing plate 9 are restricted in the corresponding notches 8, the middle opening and closing plate 9 will not move, and except for the middle waist-shaped groove 7 which is in a vertical state, the other waist-shaped grooves 7 are in an inclined state, and except for the middle opening and closing plate, the two ends of the other opening and closing plates 9 maintain a gap with their respective notches 8, and the gap of the notch 8 gradually increases from the inside to the outside. Therefore, during the rotation of the swing rod 5, the opening and closing control plate 4 will be driven to swing left and right, and through the left and right swinging of the opening and closing control plate 4, the opening and closing plate 9 can be driven to close or separate through the cooperation of the slide rod 10 and the waist-shaped groove 7, so that the product interval on the opening and closing platform 23 is adapted to the swing material interval of the tray plate 24, so that the product can be accurately placed on the tray plate 24 through the second suction nozzle 22.

[0033] Among them, Figure 6 As shown in FIG. 1 , when the slide bar 10 reaches the upper end of the waist-shaped groove, the distance between the central axes of the adjacent opening and closing plates is a. Figure 7 As shown in the figure, when the slide bar 10 reaches the lower end of the waist-shaped groove, the distance between the central axes of the adjacent opening and closing plates is b. Since the length of a is greater than the length of b, when the slide bar reaches the upper end of the waist-shaped groove, the opening and closing plates are in an open state, and when the slide bar reaches the lower end of the waist-shaped groove, the opening and closing plates are in a closed state.

[0034] The suction nozzle described in this embodiment is a part of the vacuum adsorption device, and the vacuum adsorption device is a prior art and will not be described in detail in this embodiment.

[0035] Example 2

[0036] The difference between this embodiment and the first embodiment is that the two fixing blocks 11 are provided with relative infrared transmitters 17 and infrared receivers 18. The infrared transmitter 17 transmits infrared rays, and the infrared receiver 18 receives infrared rays. As long as the product is higher, the infrared rays can be blocked, which is mainly used to confirm whether any product has escaped from the closing platform.
