Description

Technical Field

[0001] This utility model relates to the technical field of piezoelectric ceramic processing equipment, and in particular to a piezoelectric ceramic polarization feeding and discharging device. Background Technology

[0002] Piezoelectric ceramics only exhibit the piezoelectric effect after undergoing a polarization process. Polarization involves applying a strong DC electric field to the piezoelectric ceramic, causing the domains within the ceramic to align oriented along the direction of the field. Only under the influence of a polarization electric field can the domains within the piezoelectric ceramic align oriented along the field direction; and the higher the polarization electric field, the greater the effect of domain directional alignment, resulting in more complete polarization. The polarization process is a crucial step in the production of piezoelectric ceramics. Currently, the polarization of piezoelectric ceramics is primarily done manually, involving placing and removing single or multiple piezoelectric ceramics into a polarization tank. This operation is inconvenient, requires significant physical exertion from operators, and is laborious, resulting in low polarization efficiency. Improvements are necessary. Utility Model Content

[0029] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of this utility model clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention.

[0031] Reference Figure 1 As shown, a piezoelectric ceramic polarization loading and unloading device includes a polarization tank 1, a loading and unloading platform 2, a conveying mechanism 3, and a support plate 4 assembled together. The support plate 4 is used to clamp the piezoelectric ceramic parts to be polarized, and the conveying mechanism 3 is used to realize the transfer of the support plate 4 between the polarization tank 1 and the loading and unloading platform 2, thereby achieving the purpose of piezoelectric ceramic polarization loading and unloading.

[0032] Combination Figures 2-4 As shown, the polarization tank 1 is composed of multiple polarization tank units arranged side by side. Each polarization tank unit has a polarization chamber for placing the support plate 4 containing the piezoelectric ceramic. The loading and unloading platform 2 is located away from the polarization tank 1 and is used to load and unload the piezoelectric ceramic in the support plate 4. The conveying mechanism 3 includes a support frame 3-1, a crossbeam 3-2 spanning the support frame 3-1, and a lifting mechanism 3-3 mounted on the crossbeam 3-2. The crossbeam 3-2 is slidably mounted on the support frame 3-1, and the lifting mechanism 3-3 is slidably mounted along the axial direction of the crossbeam 3-2. In this way, the lifting mechanism 3-3's own lifting function enables back-and-forth movement along the X, Y, and Z axes, thereby achieving precise conveying of the support plate 4.

[0033] Combination Figure 5 As shown, the support frame 3-1 includes a square walking frame 3-1-1, a column 3-1-2, a fixing accessory 3-1-3, and a first rack 3-1-4. The walking frame 3-1-1 is installed on the column 3-1-2 to form a suspended structure. The fixing accessory 3-1-3 is used to fix the square frame 3-1-1 to the wall 5, thereby better stabilizing the square frame 3-1-1. The first rack 3-1-4 is installed on the walking frame 3-1-1. The crossbeam 3-2 is arranged across the walking frame 3-1-1 and cooperates with the first rack 3-1-4.

[0034] In this embodiment, the column 3-1-2 is preferably a triangular column, positioned at the four corners of the walking frame 3-1-1. Each triangular column includes three supports, connected to the vertex of the corresponding corner and the adjacent two sides, respectively. The supports are connected by short rods to form a triangular structure, thus providing high support strength for the entire column structure and effectively supporting the walking frame 3-1-1 and the devices on it. Furthermore, it is preferable to also connect a Y-shaped support 3-1-5 to the walking frame 3-1-1 for better stability.

[0035] Combination Figure 6 As shown, a beam drive mechanism is provided on the beam 3-2. The beam drive mechanism includes a first drive motor 3-4-1, a first reduction mechanism 3-4-2, a transmission rod 3-4-3, and a travel gear 3-4-4. The first drive motor 3-4-1 is connected to the inner ends of the two transmission rods 3-4-3 through the first reduction mechanism 3-4-2, so that the two transmission rods 3-4-3 rotate synchronously. The outer ends of the two transmission rods 3-4-3 are respectively connected to the travel gear 3-4-4, and the travel gear 3-4-4 meshes with the first rack 3-1-4.

[0036] During operation, the first drive motor 3-4-1 drives the two walking gears 3-4-4 to rotate synchronously. The two walking gears 3-4-4 have the same specifications, thereby enabling the crossbeam 3-2 to move back and forth on the support frame 3-1.

[0037] Combination Figure 6 , Figure 7 As shown, the lifting mechanism 3-3 includes a traveling frame 3-3-1 and a lifting frame 3-3-2. The traveling frame 3-3-1 is slidably installed back and forth along the axial direction of the crossbeam 3-2, and the lifting frame 3-3-2 and the traveling frame 3-3-1 form a lifting connection.

[0038] A second drive motor 3-5-1, a second reduction mechanism 3-5-2, and a drive gear 3-5-3 are provided on the walking frame 3-3-1, and a second rack 3-4-5 is axially arranged on the crossbeam 4-2. When the lifting mechanism 3-3 is assembled onto the crossbeam 3-2, the drive gear 3-5-3 meshes with the second rack 3-4-5. During operation, the second drive motor 3-5-1 drives the drive gear 3-5-3 to rotate in both directions, thereby enabling the lifting mechanism 3-3 to move back and forth along the axial direction of the crossbeam 3-2.

[0039] A third drive motor 3-6-1 and a synchronous transmission rod 3-6-2 are provided on the walking frame 3-3-1. The synchronous transmission rod 3-6-2 connects the third drive motor 3-6-1 and the lifting frame 3-3-2. During operation, the lifting frame 3-3-2 is raised and lowered by the forward and reverse rotation of the third drive motor 3-6-1.

[0040] The lifting frame 3-3-2 is a cubic frame made of several hollow tubes. At the top of the cubic frame, there are two connecting plates 3-3-3 that are connected to the two synchronous transmission rods 3-6-2. Side sealing plates 3-3-4 are provided on the two opposite sides of the cubic frame. Each side sealing plate 3-3-4 is provided with a downwardly extending hanging plate 3-3-5. Hooks 3-3-6 are provided on the hanging plates 3-3-5 for hanging the bearing plate 4.

[0041] In this embodiment, by configuring the lifting mechanism 3-3 as a frame structure including the walking frame 3-3-1 and the lifting frame 3-3-2, the weight of the lifting mechanism 3-3 is effectively reduced while ensuring structural strength, thus lowering the operating power requirements of the entire material handling device. Simultaneously, by providing the connecting plate 3-3-3, side sealing plate 3-3-4, and hanging plate 3-3-5, the lifting frame 3-3-2 of the frame structure is easily connected to the walking frame 3-3-1 and the bearing plate 4, and the connection is stable and reliable, meeting the material handling requirements of the bearing plate 4, which is loaded with multiple piezoelectric ceramics (of considerable weight).

[0042] Combination Figure 8 As shown, the supporting plate 4 includes a square plate body 4-1 and hanging ears 4-2 disposed at the four corners of the plate body 4-1. Obviously, the specific shape of the plate body 4-1 and the specific position of the hanging ears can be appropriately adjusted according to different actual needs, and are not limited to this embodiment.

[0043] This embodiment provides a piezoelectric ceramic polarization loading and unloading device, the working principle of which is as follows: a) Several piezoelectric ceramics are placed on the support plate 4 according to process requirements. b) The first drive motor 3-4-1 is activated to drive the support plate 4 to move along the Y-axis to above the polarization tank 1. c) The second drive motor 3-5-1 is activated to drive the support plate 4 to move along the X-axis to directly above the polarization tank 1. d) The third drive motor 3-6-1 is activated to drive the support plate 4 to move downward along the Z-axis to an appropriate position inside the polarization tank 11. e) After the piezoelectric ceramics are polarized, the third drive motor 3-6-1 is activated to drive the support plate 4 to move upward along the Z-axis to directly above the polarization tank 11. f) The second drive motor 3-5-1 is activated to drive the support plate 4 to move along the X-axis to above the polarization tank 1. g) The first drive motor 3-4-1 is activated to drive the support plate 4 to move along the Y-axis away from above the polarization tank 1 to the loading / unloading platform 2, where the operator removes the polarized piezoelectric ceramics.

[0045] It should be noted that, depending on the actual needs, those skilled in the art may use other existing or future known power mechanisms to replace the drive motor, as long as they can provide power to drive the corresponding device to move back and forth.
