[0002] Piezoelectric ceramics are a special type of ceramic material that has the piezoelectric effect, that is, a material that can change size or generate an electric charge when an electric field is applied. This material is usually composed of lead magnesium titanate, etc., and its structure enables it to produce a piezoelectric effect. Piezoelectric ceramics have important applications in industry and scientific research, especially in acoustics, precision control and sensing technology. During the processing of piezoelectric ceramics, a transfer suction cup is needed to adjust the processing position of the piezoelectric ceramics.

[0003] The current piezoelectric ceramic transfer suction cups usually only have one set of suction cups during use, and the piezoelectric ceramic pieces usually have openings inside during the design process. When using a single set of suction cups to adsorb the piezoelectric ceramic pieces, unstable adsorption is prone to occur, and the size of the openings in the piezoelectric ceramic pieces cannot be adjusted for use.

[0026] Next, the technical solutions in the embodiments of the present invention will be described with reference to the attached drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Specific embodiment one

[0028] Please refer to Figures 1-5 , the present invention is an improved structure of a transfer suction cup for piezoelectric ceramic chips, including a moving shell 1. A suction disc 2 is arranged at the bottom of the moving shell 1. The top of the suction disc 2 is communicated with an air inlet pipe 3. The top of the air inlet pipe 3 penetrates through the outside of the moving shell 1 and is communicated with an air intake pipe 4; an adjusting component is arranged inside the moving shell 1. The adjusting component includes a driving motor 5. The output end of the driving motor 5 is fixedly connected with a rotating rod 6. The bottom of the rotating rod 6 penetrates through the inside of the moving shell 1 and is fixedly connected with a turntable 7. A rotating groove 8 is opened inside the turntable 7; a limiting component is arranged at the bottom of the moving shell 1. The limiting component includes a guide shell 9. The guide shell 9 is fixed to the bottom of the moving shell 1. The surface of the air inlet pipe 3 is fixedly connected with a slide block 10.

[0029] Specifically: The suction disc 2 is made of elastic rubber or silica gel material with good sealing performance. When the suction disc 2 adheres to the surface of the piezoelectric ceramic chip, at this time, it is communicated with an external negative pressure pump through the air intake pipe 4. When the negative pressure pump starts, the air inside the suction disc 2 is pumped out, causing the suction disc 2 to be tightly pressed against the flat surface, forming a vacuum-sealed state, achieving the function of adsorption and fixation. The rotating groove 8 is arc-shaped. When the turntable 7 rotates, the inner wall of the rotating groove 8 can push the air inlet pipe 3, so that the position of the air inlet pipe 3 approaches the rotating rod 6, achieving the adjustment function. Specific embodiment two

[0031] Please refer to Figures 1-5, on the basis of the first specific embodiment, the slider 10 is slidably connected to the inner wall of the guide housing 9, the surface of the turntable 7 is movably connected to the inner wall of the moving housing 1 through a first bearing, pneumatic valves 11 are sleeved on both sides of the surface of the air inlet pipe 4, guide grooves 12 are formed at the top and bottom of the moving housing 1, the surface of the rotating rod 6 is movably connected to the inner wall of the moving housing 1 through a second bearing, the air inlet pipe 3 is slidably connected to the inner wall of the rotating groove 8, a moving sleeve 13 is sleeved on the surface of the air inlet pipe 3, a fixing screw 14 is threadedly connected to the front side of the moving sleeve 13, brackets 15 are fixedly connected to the opposite sides of the moving sleeve 13, a clamping plate 16 is fixedly connected to the bottom of the brackets 15, a support 17 is fixedly connected to the top of the moving housing 1, and a hydraulic rod 18 is fixedly connected to the top of the support 17.

[0032] Specifically: The slider 10 is fixed to the surface of the air inlet pipe 3 and slides on the inner wall of the guide housing 9. When the turntable 7 pushes the air inlet pipe 3 to move, the movement of the air inlet pipe 3 can be limited by the slider 10, so that the air inlet pipe 3 can only move horizontally left and right. The pneumatic valves 11 can separately control the opening and closing of the two air inlet pipes 4. The clamping plate 16 is fixed to the surface of the air inlet pipe 3 through the fixing screw 14. While the piezoelectric ceramic sheet can be adsorbed and fixed by the suction cup 2, the fixing of the moving sleeve 13 can also be cancelled by reversely rotating the fixing screw 14, and the clamping plate 16 can be adjusted downward. Through the relative movement of the two air inlet pipes 4, the clamping plate 16 is driven to move to clamp the piezoelectric ceramic sheet, realizing multiple functions.

[0033] The working principle of the present utility model is as follows: The staff starts the hydraulic rod 18 through an external controller. The hydraulic rod 18 cooperates with the moving housing 1 to drive the suction cup 2 to move downward. When the inner hole of the piezoelectric ceramic sheet to be moved is relatively large, the driving motor 5 can be started through the external controller. The driving motor 5 cooperates with the rotating rod 6 to drive the turntable 7 to rotate. When the turntable 7 rotates, it pushes the air inlet pipe 3 to rotate through the rotating groove 8. The two air inlet pipes 3 drive the two suction cups 2 to move in opposite directions respectively, expanding the distance between the two suction cups 2, so that when the two suction cups 2 move downward, they can contact the surface of the piezoelectric ceramic sheet, improving the stability of adsorption and fixation;

[0034] Then start the external negative pressure pump. The external negative pressure pump extracts the air inside the suction cup 2 through the air inlet pipe 4 and the air inlet pipe 3. The suction cup 2 is tightly pressed against the surface of the piezoelectric ceramic sheet, forming a vacuum-sealed state, realizing the function of adsorption and fixation.

[0035] The standard parts used in the present utility model can all be purchased from the market, and can also be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, welding, etc. that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. The control method is automatically controlled through a control unit. The control circuit of the control unit can be realized by simple programming by those skilled in the art, which belongs to the common general knowledge in the art. Therefore, the control method and circuit connection will not be explained in detail in the present utility model.

[0036] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific embodiments described.
