Referring to fig. 1 and 2, fig. 1 and 2 are schematic structural views of an ink stability detecting apparatus 100 according to the present embodiment.

The present embodiment provides an ink stability detecting apparatus 100, which includes a can 110, a cover 120, and a testing assembly 130. The can 110 has an insulated test chamber 111 inside, and the test chamber 111 has an opening 113 for delivering ink. The lid 120 is configured to cover the opening 113 so that the test chamber 111 is an insulated sealed chamber. The test assembly 130 is used to test the ink.

The present application performs electrical performance testing on conductive paste, so the test chamber 111 needs to be an insulating chamber. The properties of the test chamber 111 itself are prevented from adversely affecting the detection. In the present embodiment, the can 110 is made of an insulating material, and the test chamber 111 is insulating. The test chamber 111 is used to contain a conductive paste, such as ink, to be tested. The size and structure of the test chamber 111 may meet the test requirements, and the application is not limited thereto. In this embodiment, the test chamber 111 is a cylinder.

The test chamber 111 has an opening 113 for transferring ink, and conductive paste such as ink is added to or poured out of the test chamber 111 through the opening 113. Since centrifugation or other operations may be required during the testing process, the opening 113 is covered with a cover 120 matching with the opening 113 for normal testing, so that the testing chamber 111 is an insulated closed chamber. In this application, the connection manner between the cover 120 and the opening 113 may be a threaded connection, a snap connection, or the like, which is not limited in this application.

A first electrode 140 and a second electrode 150 are disposed in the testing chamber 111 and parallel to each other, and the first electrode 140 and the second electrode 150 are disposed at two opposite ends of the testing chamber 111 respectively. The stability of the ink is detected by detecting the resistivity of the ink between the opposite parallel electrodes. The electrodes in the embodiments of the present application are all general components in the technical field, and the present application does not limit the same.

Referring to fig. 1, as an implementation manner, the testing chamber 111 has a top end 115 and a bottom end 117, the opening 113 is disposed at the top end 115, the bottom end 117 is disposed with a first electrode 140, and the bottom of the cover 120 is disposed with a second electrode 150. It should be noted that the top end 115 and the bottom end 117 in this embodiment are relative to the placing direction of the can 110 during the detection, that is, the top end 115 and the bottom end 117 are relative to the horizontal plane. The stability of the slurry is essentially the degree of change over time in the state of dispersion in which the substances in the slurry are dispersed by the action of gravity. Therefore, when the resistivity of the conductive paste is detected, the resistivity of the paste in the direction of sedimentation is detected.

The first electrode 140 and the second electrode 150 have the same size to ensure the accuracy of the detection result, and further, the cover 120 has the same size as the bottom wall of the test chamber 111 to ensure the detection range and the accuracy of the detection result, which can sufficiently test the conductive ink at various positions in the test chamber 111.

In order to ensure that the second electrode 150 on the cover 120 can be in close contact with the ink in the test chamber 111 and the detection can be performed normally, the bottom of the cover 120 has a protrusion 121, the size of the protrusion 121 matches with the opening 113, when the cover 120 is covered on the can 110, the protrusion 121 extends into the opening 113 and is disposed in the test chamber 111 to close the opening 113, and the second electrode 150 is disposed on the protrusion 121. The structure reduces the distance between the second electrode 150 and the first electrode 140, so that the second electrode 150 is immersed into the upper surface of the ink in the test chamber 111 to a certain depth, and good contact between the second electrode 150 and the ink is ensured.

In one possible implementation, the protrusion 121 is made of an elastic material, and the size of the protrusion 121 is not smaller than the size of the opening 113. The convex part 121 of the elastic material extends into the test cavity 111 and can be fully contacted with the side wall of the test cavity 111, so that a gap is prevented from being reserved between the convex part 121 and the side wall, and the sealing performance is ensured. In other embodiments of the present application, the material of the protrusion 121 and the cover 120 may be other materials having the same function, and the present application is not limited thereto.

In the above solution, in order to further ensure sufficient contact between the second electrode 150 and the ink, the inner wall of the test chamber 111 is provided with a scale mark 119, and the distance between the scale mark 119 and the opening 113 is not greater than the height of the protrusion 121. When ink is filled into the test chamber 111, the volume of the ink is controlled according to the position of the graduation mark 119, so that the second electrode 150 can be sufficiently contacted with the ink when the cover 120 is covered on the test chamber 111.

Referring to fig. 3, fig. 3 is another structural schematic diagram of the testing chamber 111.

As another implementation, the testing chamber 111 has a top end 115 and a bottom end 117, the first electrode 140 is disposed at the bottom end 117, the second electrode 150 is disposed at the top end 115, and the opening 113 is disposed at a sidewall of the testing chamber 111. The first electrode 140 and the second electrode 150 in the test chamber 111 are fixedly connected to the inner wall of the test chamber 111. In the actual test, the amount of ink added is ensured so that it fills the entire test chamber 111.

Since the wall of the can body 110 has a certain thickness, the bottom of the cover 120 has a protrusion 121, the protrusion 121 is matched with the opening 113 in size, and when the cover 120 is covered on the can body 110, the protrusion 121 extends into the opening 113 and closes the opening 113. Further, the length of the protrusion 121 is equal to the thickness of the wall of the can body 110. The structure ensures the integrity of the shape of the test chamber 111 and avoids the influence of the convex part 121 on the detection on the inner wall of the test chamber 111.

In a possible implementation manner, the opening 113 is disposed at the top of the sidewall of the test cavity 111, which reduces the acting force of the ink in the test cavity 111 on the cover 120, and prevents the cover 120 from separating from the test cavity 111 to cause ink leakage.

Referring to fig. 4, the testing assembly 130 includes an ac testing module 131, a dc testing module 132, a signal collector 133 and a signal emitting device 134, the ac testing module 131 is electrically connected to the first electrode 140 and the second electrode 150, the ac testing module 131 is electrically connected to the dc testing module 132 and the signal collector 133, and the signal emitting device 134 is electrically connected to the signal collector 133. It should be noted that the electrical connection in this application is a general technology in the field, that is, communication between electrical appliances is realized, for example, by using the wire 160. The specific connection manner of the wire 160 is a general technique in the field, and the application is not limited thereto.

In this embodiment, the dc module 132 is a battery box, and a battery is disposed therein. The dc module 132 provides power to the ac testing module 131, and the ac testing module 131 converts the dc power into ac power with different frequencies and different voltage values and provides power to the first electrode 140 and the second electrode 150. Because the direct current power supply can cause ions to generate a polarization effect, and the polarization of the ions has a large influence on the test result, the alternating current test module 131 provides the alternating current power supply, the voltage of the alternating current test module 131 is less than 5V, and the power frequency is 10Hz to 100000 Hz. Optionally, the power voltage is less than 500mV, the power frequency is 50Hz to 10000Hz, further, the power voltage is less than 200mV, and the power frequency is 200Hz to 1000 Hz. The voltage and power frequency of the condition are short, the electrode response time is short, and stable numerical values are achieved in a short time, so that the reading is accurate, the data reading time is short, the efficiency is high, and the result is accurate.

After the first electrode 140 and the second electrode 150 are powered on, the detected data are transmitted to the signal collector 133 through the ac testing module 131, and then transmitted to the signal receiving and data displaying module 170 through the signal transmitting device 134. It should be noted that the ac testing module 131, the dc testing module 132, the signal collector 133 and the signal transmitting device 134 in this application are all general devices in this technical field, and the specific working principle and operation mode thereof are also general technologies in this technical field, which are not limited in this application.

the present embodiment further provides an ink stability detecting system (not shown) based on the ink stability detecting apparatus 100, which includes a centrifuge (not shown) and the ink stability detecting apparatus 100. The centrifuge is used to centrifuge the ink in the ink stability detection apparatus 100. Since the natural settling of a slurry such as ink is slow, it takes a long time to test the stability of the ink. Therefore, the process of simulating natural sedimentation is accelerated by adopting a centrifugal method, stability test is carried out on the printing ink, and the change of the detection value reflects the change of the printing ink and is used for judging the stability of the printing ink. The volume resistivity of the ink after several months or one year can be obtained through different centrifugal force and centrifugal time, and the test period is shortened. The detection method of the system is fast and does not need to wait for a long time.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
