Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of ceramic green sheet testing equipment, specifically relating to a quality testing device for ceramic green sheets. Background Technology
[0002] When manufacturing ceramic capacitor dielectric chips, ceramic capacitor dielectric material is first obtained by spray granulation. Then, larger particles and iron impurities are removed by screening. The material is then pressed into green sheets by a pressing machine and sintered to obtain ceramic blanks. After sintering, the green sheets need to be inspected for appearance quality to prevent them from breaking or containing impurities.
[0003] Existing patent CN222267932U discloses a detection device for ceramic green sheets. Its description states that "the control module controls the motor 34 to start based on image data. The motor 34 drives the lead screw 33 to rotate, causing the slider 32 to slide the horizontal plate 35 on the support frame 31 above the green sheet. At this time, the control module controls the vacuum pump 38 to start, causing the suction nozzle 37 to pick up the green sheet, moving it away from the light-transmitting element 4. Then, the control module controls the motor 34 to rotate in one direction, causing the lead screw 33 to rotate in the opposite direction, causing the slider 32 to slide the horizontal plate 35 on the support frame 31 above the defective product box 6. The control module then controls the corresponding solenoid valve 36 to close. At this time, the corresponding suction nozzle 37 has no suction force, and the defective green sheets naturally fall into the defective product box 6, while the good green sheets naturally fall into the good product box 7, and so on. Through the above steps, the effect of automatically screening defective and good green sheets during detection is achieved." This method requires a significant amount of time to detect one set of green sheets, and the detection continuity is low, failing to meet the needs of modern production.
[0004] Therefore, in order to solve the above problems, it is necessary to design a quality inspection device for ceramic green sheets. Utility Model Content

[0010] Furthermore, a cylinder is provided on the base plate; The cylinder is electrically connected to the main control module; The main control module is adapted to extend the cylinder extension end when it is determined that the current green sheet is unqualified, so as to lift one end of the transparent plate and make the transparent plate rotate upward so that the unqualified green sheet slides off the transparent plate.
[0011] Furthermore, a connecting plate is connected to the telescopic end of the cylinder; The other end of the connecting plate is connected to a top rod; wherein The top rod is adapted to contact the transparent plate.
