Description

Technical Field

[0001] The utility model belongs to the technical field of screen processing of electrode paste, and particularly relates to a combined adjusting device for a screen printing frame of a piezoelectric ceramic sheet electrode paste. Background Technique

[0002] The adjusting device for the screen printing frame of the piezoelectric ceramic sheet electrode paste is a device used to control and adjust the contact pressure between the screen printing frame and the piezoelectric ceramic sheet. It usually includes a mechanical component capable of applying pressure (for example, a pressure roller or a pressure rod), and an electric or manual adjusting device for precisely adjusting the magnitude of the pressure and the application time. The purpose of this device is to ensure that the electrode paste can be printed evenly and precisely on the surface of the piezoelectric ceramic sheet to meet the requirements of product design and manufacturing.

[0003] In the existing combined adjusting device for the screen printing frame of the piezoelectric ceramic sheet electrode paste, when adjusting the lateral position of the printing frame, it is not convenient to adjust the pressure applied to the printing frame at the same time. Most of them require two adjusting devices to work separately, but the synchronism of the two driving forces is poor, and it is easy to cause pressure changes due to lateral adjustment, which cannot ensure the uniformity and thickness consistency of the printed paste, affecting the adjustment efficiency.

[0004] Therefore, we provide a combined adjusting device for a screen printing frame of a piezoelectric ceramic sheet electrode paste to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a combined adjusting device for a screen printing frame of a piezoelectric ceramic sheet electrode paste, which solves the problem that the existing combined adjusting device for the screen printing frame of the piezoelectric ceramic sheet electrode paste is not convenient to adjust the lateral position and pressure of the printing frame at the same time through the cooperation of an adjusting component and a pressure component.

[0036] The working principle of the present utility model is as follows: When it is necessary to perform combined adjustment on the piezoelectric ceramic sheet electrode paste screen printing frame, first install the bottom plate 1 at the required installation and processing location through the installation holes, then place the printing frame on the top of the bottom plate 1, and then start the biaxial motor 14. The biaxial motor 14 drives the second screw rod 15 to rotate when working. The second screw rod 15 causes the two threaded sleeves 16 to move relatively. The threaded sleeves 16 drive the two right-angle plates 2 to move relatively. The right-angle plates 2 enable the clamping plates 7 to contact the front and back surfaces of the printing frame;

[0037] At this time, the driving motor 9 can be turned on. The driving motor 9 drives the first screw rod 10 to rotate. The first screw rod 10 drives the slider 11 to move and the driving bevel gear 17 to rotate. The slider 11 drives the spring rod 12 to move, and the spring rod 12 drives the pressure plate 13 to move, so that the bottom of the pressure plate 13 contacts one side of the top of the printing frame to generate pressure. At the same time, the driving bevel gear 17 drives the driven bevel gear 8 to rotate, the driven bevel gear 8 drives the bidirectional lead screw 5 to rotate, the bidirectional lead screw 5 drives the two sliding sleeves 6 to move relatively, and the two sliding sleeves 6 drive the two clamping plates 7 to move relatively, so as to adjust and limit the front and rear ends of the printing frame. The moving range of the pressure plate 13 is small. When the pressure plate 13 contacts one side of the top of the printing frame to generate pressure and the clamping plate 7 does not contact the printing frame, the driving motor 9 continues to work to squeeze the spring rod 12 by the pressure plate 13, so that the clamping plate 7 has enough moving distance to adjust and limit the printing frame.
