[0017] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-4 As shown, a chip transfer device includes a mounting seat 1; a storage portion, which is arranged on the mounting seat 1 and is used to store chips 2; a silk screen device 3, which is arranged on one side of the mounting seat 1; a transfer portion, which is used to transfer the chips 2 to the silk screen device 3; a material transfer portion, which is used to pick up the chips 2 in the storage portion and transfer the picked-up chips 2 to the transfer portion, and at the same time transfer the silk screen-printed chips 2 on the transfer portion; and a power portion, which is used to drive the transfer portion and the material transfer portion to move.

[0019] Furthermore, the storage portion includes a base plate 4, on which two fixed arc plates 5 are symmetrically arranged, and also includes an arc baffle 6 that is simultaneously assembled with the two arc plates 5. Two guide rods 7 are provided on the base plate 4, and the guide rods 7 are slidably connected to the arc baffle 6. A handle 8 is provided on one side of the arc baffle 6. When placing the chip 2, the arc baffle 6 is first controlled by the handle 8 to move upward along the guide rod 7 so that the side of the arc plate 5 is exposed, and then the same number of chips 2 are placed on the sides of the two arc plates 5, and the chips 2 are neatly stacked, and then the arc baffle 6 is controlled by the handle 8 to move downward, and the movement of the chip 2 is limited by the arc plate 5 and the arc baffle 6, thereby completing the placement of the chip 2.

[0020] Furthermore, the transfer part includes a main shaft 9, which is rotatably connected to the mounting base 1, and a support plate 10 is provided at the upper end of the main shaft 9. Two placing tables 11 are symmetrically provided on the supporting plate 10, and two placing grooves 12 are provided on the placing table 11. The mounting base 1 is provided with an annular support part 13, and the support part 13 is located below the supporting plate 10. The two placing grooves 12 on the placing table 11 are used to place chips 2 respectively, and each placing groove 12 only places one chip 2 at a time. After the placement of the chip 2 is completed by the material moving part, the main shaft 9 is controlled to rotate by the power part, and then the supporting plate 10 is driven to rotate, and the supporting plate 10 drives the placing table 11 to rotate, and then the chip 2 placed on the placing table 11 is moved to the bottom of the silk screen printing equipment 3, and the chips 2 in the two placing grooves 12 are silk-screened by the silk-screen printing equipment 3. During the silk-screen printing process, the chips 2 in the two placing grooves 12 on the other placing table 11 that have completed silk-screening can be taken out through the material moving part, and the new chip 2 is placed in the placing groove 12.

[0021] The screen printing device 3 is prior art and will not be described in detail here.

[0022] Furthermore, the material moving part includes a secondary shaft 14, which is rotatably connected to the mounting base 1, and a shell 15 is provided at the upper end of the secondary shaft 14. A cylinder 16 is provided inside the shell 15, and the output end of the cylinder 16 passes through the shell 15 and extends to the outside of the shell 15. A cross-shaped top plate 17 is provided on the top of the output end of the cylinder 16, and side plates 18 are provided at the four ends of the top plate 17 respectively. A vertical rod 19 is provided on the lower surface of the side plate 18, and a stopper 20 is provided at the bottom end of the vertical rod 19. It also includes a vacuum suction cup 21, and a fixed seat 22 slidably connected to the vertical rod 19 is provided on one side of the vacuum suction cup 21. A spring 23 is provided on the vertical rod 19, and the spring 23 is located between the fixed seat 22 and the side plate 18.

[0023] When the chip 2 in the storage portion is transferred to the placement groove 12 through the material transfer portion, the output end of the cylinder 16 is first controlled to extend, and the top plate 17 is pushed upward by the output end of the cylinder 16 until the suction cup assembly is completely moved to the upper end of the curved plate 5, and then the secondary shaft 14 is controlled to rotate by the power unit, and the secondary shaft 14 drives the shell 15 and the cylinder 16 in the shell 15 to rotate. When the cylinder 16 rotates, it drives the top plate 17 to rotate, and drives the suction cup assembly to rotate through the top plate 17. When the suction cup assembly is directly above the storage portion, the power unit stops moving, and then controls the output end of the cylinder 16 to retract, driving the top plate 17 to move downward, and driving the suction cup assembly downward through the vertical rod 19, spring 23, fixed seat 22 and stopper 20. When the suction cup assembly contacts the chip 2 on the storage portion, the suction cup assembly is started to adsorb the contacted chip 2. At the same time, the suction cup assembly located directly above the placement groove 12 is also in contact with the chip 2 in the placement groove 12. At this time, the suction cup assembly can also adsorb the chip 2 in the placement groove 12 The suction cup assembly is then lifted by the cylinder 16 to facilitate the movement of the chip 2 that has not been screen printed on the placement table 11 to the screen printing equipment 3 for screen printing.

[0024] Furthermore, the power unit includes a main gear 24 and a slave gear 25. The main gear 24 and the slave gear 25 are both located inside the mounting base 1. The number of teeth of the main gear 24 is half of the number of teeth of the slave gear 25. The main gear 24 is fixedly connected to the main shaft 9, and the slave gear 25 is fixedly connected to the secondary shaft 14. A motor 26 for driving the main shaft 9 to rotate is provided at the bottom of the mounting base. When the motor 26 is started, the motor 26 drives the main shaft 9 to rotate, and drives the main gear 24 on the main shaft 9 to rotate. Through the external engagement between the main gear 24 and the slave gear 25, the secondary shaft 14 is driven to rotate. The gear ratio of the main gear 24 to the slave gear 25 is one to two. Therefore, for every 180° rotation of the support disk 10, the top plate 17 only rotates 90°.

[0025] Furthermore, a conveyor belt 27 is provided on the upper surface of the mounting seat, and the suction cup assembly moves the chip 2 that has completed silk screen printing to the top of the conveyor belt 27. When the suction cup assembly is controlled to move downward by the cylinder 16, the chip 2 can be moved onto the conveyor belt 27, and then the suction cup assembly stops adsorbing the chip 2. When the cylinder 16 pushes the suction cup assembly to lift, the conveyor belt 27 can transfer the chip 2 placed above it out.

[0026] When the device is in use, the movement, lifting and rotation of the suction cup assembly can be controlled to simultaneously transfer the chips 2 at different positions, thereby effectively improving the silk screen printing efficiency and achieving good use effects.

[0027] In the description of this utility model, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
