Description

Technical Field

[0001] The utility model belongs to the technical field of piezoelectric ceramic sheet processing equipment, and particularly relates to a vacuum suction disc with a self-protection cover. Background Technique

[0002] The green cutting of piezoelectric ceramic sheets refers to a key step in the preparation process of piezoelectric ceramic materials. The mixed piezoelectric ceramic powder is made into blanks or green bodies through forming processes (such as injection molding, pressing, etc.). Green cutting is the process of cutting the formed large ceramic material into small pieces of predetermined size and shape. This step usually uses precision cutting equipment, such as a drill press, wire cutting machine or laser cutting machine. During the cutting process of piezoelectric ceramic sheet green bodies, a vacuum suction disc is needed to move the piezoelectric ceramic sheet green bodies to facilitate subsequent processing.

[0003] At present, during the movement of piezoelectric ceramic sheet green bodies using a vacuum suction disc, since most vacuum suction cups are made of rubber material, they will be worn to a certain extent after long-term use, resulting in a decrease in airtightness. Ceramic dust easily enters the conveying pipeline. After long-term use, it will adhere to the inner wall of the pipeline, causing blockage and affecting the normal use of the equipment.

[0004] Therefore, we provide a vacuum suction disc with a self-protection cover to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a vacuum suction disc with a self-protection cover. Through the cooperation of a protection component and a reset component, it solves the problem that in the prior art, ceramic dust of the vacuum suction disc for piezoelectric ceramic sheet green bodies easily enters the conveying pipeline, and after long-term use, it will adhere to the inner wall of the pipeline, causing blockage and affecting the normal use of the equipment.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present utility model will be described in conjunction with the drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Specific embodiment one

[0030] Please refer to Figure 1-6 , the present utility model is a vacuum suction disc with a self-protective cover, including a vacuum tube 1. The bottom of the vacuum tube 1 is communicated with a suction disc 2, and a hydraulic rod 3 is installed at the top of the vacuum tube 1; a protection assembly is arranged on the surface of the vacuum tube 1. The protection assembly includes a support tube 4, and the support tube 4 is fixedly connected to the surface of the vacuum tube 1. Support seats 5 are fixedly connected to both sides of the support tube 4. A support shaft 6 is movably connected inside the support seat 5. An adjusting rod 7 is fixedly connected to the surface of the support shaft 6. A protection plate 8 is fixedly connected to one side of the adjusting rod 7. Baffles 9 are arranged on the front side and the rear side of the adjusting rod 7; a reset assembly is arranged on the surface of the support tube 4. The reset assembly includes a traction rope 10, and the traction rope 10 is fixedly connected to one side of the baffle 9. A guide ring 11 is sleeved on the surface of the traction rope 10.

[0031] Specifically: The suction cup 2 is made of rubber or silica gel and has good sealing performance. When the suction cup 2 contacts and adheres to the green body of the piezoelectric ceramic sheet, it is connected to an external negative pressure pump through the air pipe 17, and air is pumped out from the suction cup 2. The pumped-out air will form a low-pressure area on the surface where the suction cup 2 contacts the green body of the piezoelectric ceramic sheet. Under the action of atmospheric pressure, the external air will push the object towards the surface of the suction cup, increasing the contact area and further improving the adsorption force. The number of protection plates 8 is two groups. When the two groups of protection plates 8 move relatively and adhere to each other, they can form a sealed circular plate to improve the anti-detachment effect. The number of baffles 9 is four and is divided into two groups. When the two baffles 9 in the same group rotate relatively, they can form a semi-circular plate to play a role in shielding the green body of the piezoelectric ceramic sheet. Specific Embodiment 2

[0033] Please refer to Figure 1-6 , on the basis of Specific Embodiment 1, the reset assembly further includes an electric push rod 12. The electric push rod 12 is fixedly connected to one side of the support tube 4. A moving ring 13 is sleeved on the surface of the support tube 4. The output end of the electric push rod 12 is fixedly connected to the moving ring 13. The other end of the traction rope 10 is fixedly connected to the moving ring 13. A first spring 14 is sleeved on the surface of the traction rope 10. Both ends of the first spring 14 are fixedly connected to the guide ring 11 and the baffle 9 respectively. A second spring 15 is sleeved on the surface of the support shaft 6. Both ends of the second spring 15 are fixedly connected to the adjusting rod 7 and the support 5 respectively. A rotating rod 16 is fixedly connected inside the adjusting rod 7. One side of the baffle 9 is fixedly connected to the rotating rod 16. One side of the guide ring 11 is fixedly connected to the adjusting rod 7. The baffle 9 is arc-shaped. The rear side of the vacuum tube 1 is communicated with an air pipe 17, and a pneumatic valve 18 is sleeved on the surface of the air pipe 17.

[0034] Specifically: The traction rope 10 is made of steel cable, which can improve the pulling force. One end of the traction rope 10 is fixedly connected to the moving ring 13, and the other end of the traction rope 10 is divided into two, and the two separated ends are respectively fixed to the two baffles 9. The number of guide rings 11 is two, and both are fixedly connected to the adjusting rod 7, which can drive the two baffles 9 to rotate simultaneously when the traction rope 10 is pulled. The second spring 15 is a torsion spring, which can play an elastic reset role for the support shaft 6. The elastic force of the second spring 15 is twice that of the first spring 14, which can drive the adjusting rod 7 to rotate preferentially when the traction rope 10 is released.

[0035] The working principle of the present utility model is as follows: The staff starts the hydraulic rod 3 through an external controller. The hydraulic rod 3 drives the suction cup 2 to contact the green body of the piezoelectric ceramic sheet, and starts the external negative pressure pump to adsorb and fix the green body of the piezoelectric ceramic sheet through the suction cup 2;

[0036] When it is necessary to move the green body of the piezoelectric ceramic sheet over a long distance, the electric push rod 12 can be activated. The electric push rod 12 drives the moving ring 13 to move downward, releasing the traction rope 10. At this time, since the elastic force of the second spring 15 is twice that of the first spring 14, when the traction rope 10 is released, the adjusting rod 7 can be preferentially driven to rotate. The adjusting rod 7 cooperates to drive the protection plate 8 to rotate around the support shaft 6, and the two protection plates 8 are brought into contact to shield the bottom of the green body of the piezoelectric ceramic sheet and prevent ceramic dust from entering the vacuum pipeline.

[0037] After that, the traction rope 10 is continuously released. When the two protection plates 8 are in contact, the first spring 14 will reset the baffle plate 9, and the baffle plate 9 will rotate around the rotating rod 16. When the two protection plates 8 rotate relative to each other, they can form a circular plate, as Figure 6 shown, which can shield the two sides of the green body of the piezoelectric ceramic sheet and improve the dust-proof protection effect.

The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.
