Description

Technical Field

[0001] The utility model belongs to the technical field of lithium electrode sheet detection, and particularly relates to a detection device for wavy edges of lithium electrode sheets. Background Art

[0002] During the production process of lithium electrode sheets, fluctuations in the relative positions of the electrode sheet foil and the coating die head result in curved wavy edges at the coating edges and also at the slitting edges. Such wavy edges directly affect the subsequent cell casing during production and even impact the safety of the entire battery. Therefore, the control of the wavy edges of the electrode sheets is of crucial importance.

[0003] During the production process, for the detection of wavy edges, the current method adopted is off-line manual inspection: using a straight ruler to define the longitudinal reference edge, using a film ruler to measure the deviation between the actual edge and the reference edge, and statistically forming a wavy edge curve. The conventional manual inspection method is difficult to operate, has low detection accuracy, and measurement deviations may also be caused by operator differences. Summary of the Utility Model

[0004] In order to solve the technical problems of the inconvenience caused by manual inspection of the wavy edges of lithium electrode sheets in the background art, the purpose of the utility model is to provide a detection device for wavy edges of lithium electrode sheets, which can solve the above problems.

[0005] The technical solution for achieving the purpose of the utility model is: a detection device for wavy edges of lithium electrode sheets, including a detection table and a moving measurement head installed on one side of the detection table. One end of the tabletop of the detection table is provided with a first clamping mechanism for clamping a sample sheet, and the other end of the tabletop of the detection table is provided with an adjusting mechanism for adjusting the tension of the sample sheet. One end of the sample sheet is clamped by the first clamping mechanism, and the other end of the sample sheet is adjusted for tension by the adjusting mechanism.

[0006] In the detection device of this solution, the detection table is used as a support device, and the detection and measurement of the sample sheet are both carried out on the tabletop of the detection table. Therefore, a moving measurement head for movable measurement is arranged on one side of the detection table. In addition, a first clamping mechanism for fixing one end of the sample sheet is arranged at one end of the tabletop of the detection table, and the other end of the sample sheet is adjusted for tension by the adjusting mechanism, so as to facilitate the better laying of the sample sheet on the tabletop of the detection table for accurate detection. The structure of the first clamping mechanism can be various as long as it can clamp the sample sheet, such as a common clip; the adjusting mechanism can be in various forms, such as an adjusting roller and other structures. The structure of this device is simple. With the automatic detection of the moving measurement head, automatic and accurate measurement is realized, solving the problems of inaccurate measurement, low accuracy and inconvenient operation caused by manual labor. Using this device can greatly improve the accuracy and measurement efficiency.

[0007] Furthermore, the adjusting mechanism includes a plurality of adjusting rollers vertically arranged with respect to the tabletop of the detection table, and the sample piece spirally passes through the gaps between the plurality of adjusting rollers in sequence. For example, if there are three adjusting rollers, the sample piece passes through the gap between the first adjusting roller and the second adjusting roller, and then passes through the gap between the second adjusting roller and the third adjusting roller. Therefore, adjusting the position of the second adjusting roller in the horizontal direction will affect the tension of the sample piece, thus constituting an adjusting roller structure for adjusting the tension of the sample piece.

[0008] Furthermore, the plurality of adjusting rollers are, from top to bottom, a first guiding roller, a tension adjusting roller, a second guiding roller, and a second clamping mechanism in sequence. The first guiding roller is flush with the tabletop of the detection table, and the end of the other end of the sample piece is clamped in the second clamping mechanism. That is to say, the sample piece first passes through the gap between the first guiding roller and the tension adjusting roller, then passes through the gap between the tension adjusting roller and the second guiding roller, and finally is clamped and fixed on the second clamping mechanism. Since the first guiding roller, the tension adjusting roller, and the second guiding roller are vertically arranged in sequence and are position-corresponding, adjusting the position of the tension adjusting roller in the horizontal direction will adjust the tension of the sample piece, thereby achieving the purpose of the adjusting mechanism.

[0009] Furthermore, a movable groove parallel to the tabletop of the detection table is provided on the detection table, and the tension adjusting roller is movably installed in the movable groove, that is, the position of the tension adjusting roller can move horizontally in the movable groove, thereby adjusting the tension degree of the sample piece.

[0010] Furthermore, a tension detection roller is also installed between the tension adjusting roller and the second guiding roller, which is used to detect the magnitude of the tension of the sample piece. The signal of the detected tension degree can be transmitted to the control system, and then the position of the tension adjusting roller can be adaptively adjusted.

[0011] Furthermore, both the first clamping mechanism and the second clamping mechanism are clips, which are simple and practical and have a stable fixing effect.

[0012] Furthermore, a positioning pin is also provided on the inner side of the tabletop of the detection table for positioning the position of the sample piece on the tabletop. When the sample piece is placed on the tabletop of the detection table, it only needs to abut against the positioning pin on the inner side to complete the positioning and placement of the sample piece, which is convenient for the moving measuring head to perform measurements according to the preset path. At the same time, the tabletop material of the detection table can be made of marble material, which has a smooth structure, improving the flat placement of the sample piece and the measurement accuracy.

[0013] Further, a servo motion module for driving the moving measurement head is installed on one side of the inspection table, and the moving measurement head reciprocates on the servo motion module; the moving measurement head is a CCD vision inspection camera. The servo motion module is electrically controlled automatically to achieve a high degree of automation of the equipment, and the CCD vision inspection camera is an industrial professional camera with high measurement accuracy and high intelligence level.

[0014] Further, it further includes a frame. The inspection table is installed inside the frame to protect the inspection table and related components from being damaged by other components in the production space and affecting the accuracy of the measurement results. A safety grating is also provided on the frame for monitoring. When the operator approaches the moving mechanism during the inspection process, it will stop immediately to prevent personnel from being injured.

[0015] Further, it further includes an electric control cabinet. An industrial control computer and PLC electrical components are installed inside the electric control cabinet, and an operation platform is installed on the top of the electric control cabinet. Electrical components such as PLC realize the power supply and control of the measurement frame; the industrial control computer is embedded in the cabinet body and measurement software is installed to realize data acquisition, processing and storage; the top of the electric control cabinet is an operation platform for placing a keyboard, mouse and display for the operator to monitor and operate in real time, and signal lights are installed in the corner to feedback the equipment status in real time.

In the detection device of this solution, the detection table 1 is used as the support device, and the detection and measurement of the sample piece 18 are both carried out on the tabletop 3 of the detection table. Therefore, a moving measuring head 2 for movable measurement is arranged on one side of the detection table 1. In addition, a first clamping mechanism 4 for fixing one end of the sample piece 18 is arranged at one end of the tabletop 3 of the detection table, and the other end of the sample piece 18 is adjusted for tension by the adjustment mechanism 5, so as to facilitate the better laying of the sample piece 18 on the tabletop 3 of the detection table for accurate detection. The structure of the first clamping mechanism 4 can be various, as long as it can clamp the sample piece 18, such as a common clip; the adjustment mechanism 5 can be in various forms, such as a structure like an adjustment roller. The structure of this device is simple. With the automatic detection of the moving measuring head 2, it realizes automated and precise measurement, solves the problems of inaccurate measurement, low precision and inconvenient operation caused by manual operation, and can greatly improve the accuracy and measurement efficiency by using this device.

[0029] Preferably, both the first clamping mechanism 4 and the second clamping mechanism 9 are clips, which are simple and practical and have a stable fixing effect.

[0030] Preferably, a positioning pin 12 is further provided inside the tabletop 3 of the inspection table for positioning the sample piece 18 on the tabletop. When the sample piece 18 is placed on the tabletop 3 of the inspection table, it only needs to be abutted against the positioning pin 12 on the inner side to complete the positioning and placement of the sample piece 18, facilitating the movement of the measuring head 2 to perform measurements according to a preset path. At the same time, the tabletop 3 of the inspection table can be made of marble material, having a smooth structure, improving the flat placement of the sample piece 18 and the measurement accuracy.

[0033] As Figure 3As shown, the adjusting mechanism 5 includes a plurality of adjusting rollers vertically arranged with respect to the tabletop 3 of the inspection table. The sample piece 18 spirally passes through between the plurality of adjusting rollers in sequence. If there are three adjusting rollers, the sample piece 18 passes through the gap between the first adjusting roller and the second adjusting roller, and then passes through the gap between the second adjusting roller and the third adjusting roller. Therefore, adjusting the position of the second adjusting roller in the horizontal direction will affect the tension of the sample piece 18, thus constituting an adjusting roller structure for adjusting the tension of the sample piece 18. The plurality of adjusting rollers are, from top to bottom, the first guiding roller 6, the tension adjusting roller 7, the second guiding roller 8, and the second clamping mechanism 9 in sequence. The first guiding roller 6 is flush with the tabletop 3 of the inspection table, and the end of the other end of the sample piece 18 is clamped within the second clamping mechanism 9.

Since the first guiding roller 6, the tension adjusting roller 7, and the second guiding roller 8 are vertically arranged in sequence and their positions correspond to each other, adjusting the position of the tension adjusting roller 7 in the horizontal direction will adjust the tension of the sample piece 18, thereby achieving the purpose of the adjusting mechanism 5. An activity groove 10 parallel to the tabletop 3 of the inspection table is provided on the inspection table 1. The tension adjusting roller 7 is movably installed within the activity groove 10, that is, the position of the tension adjusting roller 7 can move within the activity groove 10 in the horizontal direction, thereby adjusting the tension degree of the sample piece 18. A tension detection roller 11 is further installed between the tension adjusting roller 7 and the second guiding roller 8, which is used to detect the magnitude of the tension of the sample piece 18. The signal of the tension degree collected can be transmitted into the control system, and then the position of the tension adjusting roller 7 is adaptively adjusted.

[0035] Working principle: First, place the sample piece 18 on the tabletop 3 of the detection table and align it with the positioning pins 12 on the inner side. Then, one end of the sample piece 18 is fixed by the first clamping mechanism 4, and the other end sequentially passes through the first guide roller 6, the tension adjusting roller 7, the tension detecting roller 11, and the second guide roller 8 in a spiral manner, and finally is fixed by the second clamping mechanism 9.
