Description

Technical Field

[0001] This utility model relates to a lithium-ion battery electrode size measuring device, belonging to the field of lithium battery testing technology. Background Technology

[0002] Currently, with the rapid development of the electronics and battery industries, the production process of lithium batteries demands increasingly higher precision in quality inspection, especially in the dimensional inspection of lithium battery electrodes. Most existing inspection methods rely on online measurement, but offline inspection is still necessary in certain situations. However, in practical applications, existing technologies have the following problems: First, the ruler's position is not fixed, making precise position control difficult; second, the magnifying glass's position is also not fixed, making it difficult to ensure an accurate observation angle.

[0003] After searching the existing technology, it was found that Chinese patent CN204286293U discloses a quality inspection ruler for lithium battery electrode production. The patent uses a ruler, electrode clamp and magnifying glass to measure the battery electrode. However, it was found that the position of the magnifying glass can only be moved in the horizontal direction, which cannot provide enough adjustment space for lithium battery electrodes of different sizes, which brings inconvenience to the measurement and reduces the efficiency of operation. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a lithium-ion battery electrode size measuring device that can measure lithium battery electrodes, adapt to the measurement needs of lithium battery electrodes of different specifications, and improve the efficiency and accuracy of detection.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a lithium-ion battery electrode size measuring device, comprising:

[0006] A measurement platform, the measurement platform being adapted to hold the lithium-ion battery electrode to be measured;

[0007] At least one longitudinally movable support is slidably mounted on the measuring platform along the longitudinal direction;

[0008] A length measuring component mounting bracket, wherein the length of the length measuring component mounting bracket is mounted laterally on the longitudinal movable bracket;

[0009] A length measuring component, detachably mounted on a length measuring component mounting bracket, the length measuring component having scale markings extending along the length direction;

[0010] At least one measuring sliding component is slidably disposed on the length measuring component mounting bracket, and the measuring sliding component is adapted to move along the length direction of the length measuring component;

[0011] At least one magnifying lens assembly is mounted on the measuring sliding assembly, and the central axis of the magnifying lens assembly is located on the scale markings of the length measuring assembly;

[0012] The measuring sliding component is adapted to move the magnifying lens component so as to determine the size of the lithium-ion battery electrode on the measuring platform by means of the scale markings on the length measuring component.

[0013] Furthermore, a specific type of length measuring component is provided, wherein the length measuring component is a film ruler.

[0014] Furthermore, the length measuring component mounting bracket includes:

[0015] A length measuring component support frame is mounted on the longitudinal moving bracket. The length measuring component support frame has a C-shaped structure and a long groove extending along the length direction on its side. Support grooves are formed at both ends of the long groove, and a limiting groove is formed in the middle section.

[0016] Furthermore, the lithium-ion battery electrode size measuring device also includes at least one length measuring component elastic fixing clip. The length measuring component elastic fixing clip is an elastic clamping member, which is disposed in the support groove of the length measuring component support frame. One end of the length measuring component elastic fixing clip is fixed in the support groove, and the other end forms a guide opening suitable for inserting the length measuring component. The middle section abuts against the bottom surface of the support groove.

[0017] Furthermore, the upper surface of the measuring platform is provided with a grid scale.

[0018] Furthermore, both the longitudinal moving bracket and the length measuring component mounting bracket are made of transparent acrylic sheets.

[0019] Furthermore, the measuring sliding assembly and the magnifying lens assembly are each provided in two sets.

[0020] Furthermore, each of the magnifying lens assemblies includes a first convex lens and a second convex lens arranged axially.

[0021] By adopting the above technical solution, this utility model has the following beneficial effects:

[0022] In this invention, during the measurement process, the operator places the lithium-ion battery electrode flat on the measurement platform and adjusts the position of the longitudinal moving bracket to align the length measuring component with the measurement direction of the lithium-ion battery electrode. By manually sliding the two measuring sliding components, the magnifying lens component is moved to the corresponding positions at both ends of the lithium-ion battery electrode. The operator observes the scale markings on the length measuring component through the magnifying lens component, reads the scale values ​​at the two measurement points, and calculates the difference to obtain the length of the lithium-ion battery electrode.

[0023] In addition, the elastic clamp of the length measuring component ensures the stability of the film ruler during the measurement process by elastic clamping, avoiding measurement errors caused by the movement of the film ruler; the upper surface of the measuring platform is equipped with a grid scale to provide a reference benchmark for the placement and positioning of lithium-ion battery electrodes; both the longitudinal moving bracket and the length measuring component mounting bracket are made of transparent acrylic sheet, providing good light transmission for easy observation of the measurement process.

[0024] In summary, this invention enables offline measurement of lithium-ion battery electrode dimensions, avoiding the technical problems of difficult readings and poor consistency of measurement results in traditional film ruler measurement, and providing a reliable measurement method for quality control in the lithium-ion battery manufacturing process.

[0028] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0029] Example 1

[0030] like Figure 1-3 As shown, a lithium-ion battery electrode size measuring device includes:

[0031] Measurement platform 1, which is suitable for placing the lithium-ion battery electrode to be measured;

[0032] A pair of longitudinally movable supports 2 are slidably mounted on the measuring platform 1 along the longitudinal direction;

[0033] The length measuring component mounting bracket 3 is mounted laterally on the longitudinal movable bracket 2 in the length direction of the length measuring component mounting bracket 3.

[0034] The length measuring component 4 is detachably mounted on the length measuring component mounting bracket 3 and has scale markings extending along the length direction.

[0035] A pair of measuring sliding components 5 are slidably disposed on the length measuring component mounting bracket 3, and the measuring sliding components 5 are adapted to move along the length direction of the length measuring component 4;

[0036] A pair of magnifying lens assemblies 6 are mounted on the measuring sliding assembly 5, and the central axis of the magnifying lens assembly 6 is located on the scale marking of the length measuring assembly 4;

[0037] The measuring sliding component 5 is adapted to move the magnifying lens component 6 so as to determine the size of the lithium-ion battery electrode located on the measuring platform 1 by means of the scale markings on the length measuring component 4.

[0038] In this embodiment, as Figure 1-2 As shown, during the measurement process, the operator places the lithium-ion battery electrode flat on the measurement platform 1 and adjusts the position of the longitudinal moving bracket 2 to align the length measuring component 4 with the measurement direction of the lithium-ion battery electrode. By manually sliding the two measuring sliding components 5, the magnifying lens component 6 is moved to the electrode coating area of ​​the lithium-ion battery electrode. The operator observes the scale markings on the length measuring component 4 through the magnifying lens component 6, reads the scale values ​​at the two measurement points, and calculates the difference to obtain the size of the lithium-ion battery electrode.

[0039] In addition, in this embodiment, four lithium-ion battery electrode fixing elastic clips are provided on the measuring platform 1. When placing the lithium-ion battery electrode, the electrode is unfolded and laid flat, and then inserted into the lithium-ion battery electrode fixing elastic clips.

[0040] When taking a reading from the length measuring component 4, the line of sight should be perpendicular to the reading scale to avoid errors in the reading.

[0041] Specifically, such as Figure 1 As shown, the length measuring component 4 is a film ruler.

[0042] In this embodiment, the accuracy of the film ruler is 0.1 mm.

[0043] Specifically, such as Figure 1 As shown, the length measuring component mounting bracket 3 includes:

[0044] The length measuring component support frame is installed on the longitudinal moving bracket 2. The length measuring component support frame has a C-shaped structure and a long groove extending along the length direction on its side. Support grooves are formed at both ends of the long groove and a limiting groove is formed in the middle section.

[0045] Specifically, the lithium-ion battery electrode size measuring device also includes a length measuring component elastic fixing clip (not shown in the figure). The length measuring component elastic fixing clip is an elastic clamping component, which is set in the support groove of the length measuring component support frame. One end of the length measuring component elastic fixing clip is fixed in the support groove, and the other end forms a guide opening suitable for inserting the length measuring component 4. The middle section abuts against the bottom surface of the support groove.

[0046] In this embodiment, as Figure 1 As shown, the opening height of the guide opening of the elastic fixing clamp of the length measuring component is slightly greater than the thickness of the length measuring component 4. When the length measuring component 4 is inserted, the elastic fixing clamp of the length measuring component undergoes elastic deformation, and the middle section of the elastic fixing clamp of the length measuring component contacts the length measuring component 4 to form a clamp.

[0047] The length measuring component has two elastic fixing clamps, which are located in the support grooves of the length measuring component support frame.

[0048] Specifically, such as Figure 1 As shown, the upper surface of the measuring platform 1 is provided with a grid scale.

[0049] In this embodiment, as Figure 1 As shown, the grid scale consists of mutually perpendicular graduation lines, forming a square grid network. The grid scale provides a reference for positioning the lithium-ion battery electrodes. Operators can place the lithium-ion battery electrodes in the designated positions according to the grid scale, ensuring that the electrodes are parallel and aligned with the graduation marks on the length measuring component 4.

[0050] Specifically, such as Figure 1 As shown, both the longitudinal moving bracket 2 and the length measuring component mounting bracket 3 are made of transparent acrylic sheets.

[0051] In this embodiment, as Figure 1-2 As shown, the transparent acrylic sheet material has good light transmittance and will not obstruct the observation of the lithium-ion battery electrode on the measurement platform 1.

[0052] Specifically, such as Figure 2 As shown, the measuring sliding component 5 and the magnifying lens component 6 are each provided in two sets.

[0053] Specifically, such as Figure 2 As shown, each magnifying lens assembly 6 includes a first convex lens and a second convex lens arranged axially.

[0054] In this embodiment, as Figure 1-2 As shown, two sets of measuring sliding components 5 are respectively mounted on the length measuring component mounting bracket 3, and can slide independently to different positions on the length measuring component 4. Each set of measuring sliding components 5 carries a set of magnifying lens components 6, enabling simultaneous measurement of two positions of the lithium-ion battery electrode.

[0055] In addition, the measuring sliding assembly 5 is equipped with a magnifying glass mounting cylinder. This cylinder is a hollow cylindrical structure with a limiting ring step on its inner side. Its inner diameter matches the outer diameter of the first and second convex lenses. The first and second convex lenses are slidably mounted inside the magnifying glass mounting cylinder and can be moved along the cylinder's axial direction to adjust their relative distance. A first hinge rod and a second hinge rod are provided between the first and second convex lenses. One end of the first hinge rod is hinged to the outer wall of the first convex lens, and the other end is connected to one end of the second hinge rod via a connecting bolt. The other end of the second hinge rod is also hinged to the second convex lens. When the operator tightens the hinge bolt, the relative rotation of the first and second hinge rods is restricted, thereby limiting the axial movement of the first and second convex lenses along the magnifying glass mounting cylinder.

[0056] Example 2

[0057] Specifically, such as Figure 1 and Figure 3 As shown, this embodiment is basically the same as Embodiment 1, except that it also includes a height adjustment mechanism. The height adjustment mechanism includes a height gauge 71 and a guide slider. The guide slider is slidably mounted on the longitudinal moving bracket 2 and can slide along the vertical direction of the longitudinal moving bracket 2. The length measuring component mounting bracket 3 is fixedly mounted on the guide slider and moves up and down with it. The height gauge 71 is vertically positioned next to the longitudinal moving bracket 2, maintaining a parallel relationship with it. The height gauge 71 has a first scale distributed along the vertical direction, and the guide slider has an indicator mark as a second scale, which corresponds to the first scale on the height gauge 71. By observing the position of the second scale on the height gauge 71, the operator can accurately read the height value of the length measuring component mounting bracket 3, achieving precise measurement and positioning of lithium-ion battery electrodes of different thicknesses.

[0058] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
