Description

Technical Field

[0001] The utility model relates to the technical field of gel viscosity testing, in particular to a device for testing the viscosity of a gel for a battery negative electrode. Background Art

[0002] The negative electrode refers to the end with a lower potential (electromotive force) in a power source. In a primary battery, it refers to the electrode that undergoes oxidation and is written on the left side in the battery reaction. In an electrolytic cell, it refers to the electrode that undergoes reduction, which is different from a primary battery. From a physical perspective, it is the pole where electrons flow out in a circuit. A gel is required at the negative electrode of a battery. A gel refers to a thick liquid or semi-solid preparation in the form of a solution, suspension, or emulsion prepared from a drug and an adjuvant capable of forming a gel.

[0003] After the gel for the battery negative electrode is produced, it is necessary to test the adhesion of the gel. During the adhesion test, the gel is applied to two plates, and then the vertical lifting method is used to measure the lifting force. However, each time a test is performed, it is necessary to reinstall or replace the plates for testing, which wastes a lot of time. Therefore, a device for testing the viscosity of a gel for a battery negative electrode is proposed. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a device for testing the viscosity of a gel for a battery negative electrode to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A device for testing the viscosity of a gel for a battery negative electrode includes a test base, a test bracket is installed on the test base, a test cylinder is fixedly installed on the test bracket, the output end of the test cylinder is connected with a tensile force sensor, a bottom fixing seat and a top fixing seat are respectively fixedly installed on one side of the test base and the tensile force sensor, convex plug blocks are installed on both the bottom fixing seat and the top fixing seat through installation components, and a plurality of viscosity test plates are installed on the convex plug blocks through plugging and extracting components.

[0007] Preferably, the installation component includes a convex plugging groove opened on one side of the bottom fixing seat or the top fixing seat, and the convex plug block is plugged in the convex plugging groove.

[0008] Preferably, the plugging and extracting component includes side plugging grooves opened on both sides of the convex plug block, side connecting blocks are fixedly installed on both sides of the viscosity test plate, plugging blocks are fixedly installed on one side of each of the two side connecting blocks, and the plugging blocks are adapted to the side plugging grooves.

[0009] Preferably, pull slots are opened on both sides of the viscosity test plate, and the plugging blocks are adapted to the pull slots.

[0010] Preferably, a gel coating surface is provided on one side of the viscosity test plate away from the convex plug, and a plurality of viscosity test plates are arranged in a stacked manner in sequence.

[0011] Preferably, a side plate is fixedly installed on one side of the test bracket, an operation computer is installed on the top side of the side plate, and a transmission line is connected between the operation computer and the tension sensor.

[0012] Preferably, the number of viscosity test plates on the bottom fixing base is the same as that on the top fixing base.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: when the viscosity of the gel used for the negative electrode of the battery needs to be detected by this battery negative electrode gel viscosity testing device, the gel is applied on two mutually adjacent viscosity test plates. After they are mutually adjacent and engaged and wait for a period of time, the test cylinder operates to pull the two mutually adhered viscosity test plates. The provided tension sensor can always detect the pulling force and transmit the data to the operation computer through the transmission line for display on the display screen. By continuous pulling, the adhesion degree of the gel can be known.

[0014] To ensure the accuracy of the detection, multiple detections are required. After one detection is completed, directly pull out the two mutually adjacent viscosity test plates, and pull out the viscosity test plates with the gel adhered. It is relatively convenient to pull out. There are multiple viscosity test plates both above and below. After one test, directly pull out the two mutually adjacent viscosity test plates, avoiding the problem of spending a lot of time in removing the traditional test plates back and forth. The viscosity result of the gel used for the negative electrode of the battery can be obtained through multiple tests. BRIEF DESCRIPTION OF THE DRAWINGS
