Abstract
Description
Technical Field
[0001] This utility model relates to the field of measuring tooling technology, and in particular to a tooling for measuring the parallelism between rollers in a lithium battery coating equipment. Background Technology
[0002] The battery electrode rolling mill is a key piece of equipment in the production of battery electrodes. When the battery electrode rolling mill is working, two rollers rotate synchronously on the electrode, applying a large force to ensure that the electrode reaches the required thickness and density after rolling, and that the electrode surface is smooth, flat and free of any defects. The parallelism between the rollers of the soft-pack lithium battery coating equipment directly affects the electrode yield, so it is necessary to adjust the parallelism between the rollers. During the adjustment process, the parallelism between the rollers of the lithium battery coating equipment needs to be measured using a roller parallelism measuring fixture.
[0003] The existing fixture for measuring the parallelism between rollers in lithium battery coating equipment requires manual adjustment of the fixture height to align the dial indicator with the roller. The roller is then adjusted according to the distance difference between the two ends. This process is repeated until the distance difference between the two ends of the roller reaches the required level. After manual adjustment to the required height, the position cannot be completely fixed, requiring the debugging personnel to hold it by hand throughout the process. Due to the influence of the debugging personnel, there is significant shaking, making it difficult to read the values. This process is time-consuming and has a high error rate. Utility Model Content

Detailed Implementation
[0030] The parallelism measuring fixture between rollers in a soft-pack lithium battery coating equipment provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are listed as best and preferred embodiments, and other alternative methods may be used by those skilled in the art; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0031] like Figure 1 and Figure 2As shown, an embodiment of this utility model provides a parallelism measuring fixture between rollers in a lithium battery coating equipment. This fixture can be specifically applied to soft-pack batteries. The fixture includes a guide rod assembly 1, which is composed of a first guide rod 11 and a second guide rod 12. The end of the first guide rod 11 is provided with a mounting groove 14, and the front end of the second guide rod 12 is provided with a mounting pin 13. The outer wall of the guide rod assembly 1 can slide. A slider 2 is connected, and a slide rail 3 is detachably connected to the side wall of the slider 2. A slide groove 5 is provided on the slide rail 3. A ranging unit is installed on the inner side of the slide rail 3. The guide rod assembly 1 is used to bridge between two guide rollers 10 to be measured. In the specific implementation process, one side of the two guide rollers 10 is higher than the other side. The slider 2, support block 6, and adjusting block 7 are all provided with threaded holes for locking. By tightening the bolts in the threaded holes, they can be fixed to the surface of the guide rod assembly 1. Loosening the bolts allows them to slide on the surface of the guide rod assembly 1.
[0032] like Figure 1 and Figure 3 As shown, a support block 6 is slidably connected to the outer wall of the guide rod assembly 1, and the support block 6 is configured to be located on the top of the guide roller 10 to support the guide rod assembly 1. The stability of the guide rod assembly 1 is ensured by the support block 6 contacting the top of the guide roller 10.
[0033] In some specific embodiments, the support block 6 includes a fixed base and a support plate vertically disposed on the fixed base; the support plate is provided with a through support hole, and the guide rod assembly 1 passes through the support hole and is fixed therein.
[0034] like Figure 1 and Figure 4 As shown, an adjusting block 7 is slidably connected to the outer wall of the guide rod assembly 1. The adjusting block 7 moves on the guide rod assembly 1 to bring it closer to the guide roller 10.
[0035] like Figure 1 and Figure 4 As shown, the side wall of the adjusting block 7 is detachably connected to the moving block 8.
[0036] like Figure 1 and Figure 3 As shown, a limiting rod 9 is provided on the moving block 8. The limiting rod 9 is configured to move in a direction perpendicular to the guide rod assembly 1 and restrict the guide rod assembly 1 to the position to be measured.
[0037] In some specific implementations, such as Figure 1 and Figure 4 As shown, the adjusting block 7 is an adjusting plate, and an adjusting hole is provided through it on the adjusting plate. The guide rod assembly 1 passes through the adjusting hole and is fixed.
[0038] The movable block 8 is a movable plate, which is perpendicular to the adjusting plate, and a movable hole is provided through it on the movable plate. The limiting rod 9 passes through the movable hole and is fixed.
[0039] like Figure 3 and Figure 4 As shown, a support block 6 is slidably connected to the outer wall of the guide rod assembly 1, and the moving block 8 is disposed between the support block 6 and the adjusting block 7. This arrangement achieves two advantages: firstly, it optimizes the spatial layout of the various components; secondly, the moving block 8 can be fixed by the support block 6 and the adjusting block 7, improving its stability.
[0040] In some specific implementations, such as Figure 1 and Figure 3 As shown, the ranging unit is a dial indicator 4. The dial indicator 4 is detachably connected to the slide rail 3 by bolts passing through the slide groove 5. By loosening the bolts, the position of the dial indicator 4 on the slide groove 5 can be finely adjusted.
[0041] In some specific implementations, such as Figure 1 and Figure 4 As shown, the sidewall of the slider 2 is detachably connected to the slide rail 3 by bolts;
[0042] The movable block 8 and the limiting rod 9 are connected by threads.
[0043] The technical solution provided by this utility model involves selecting guide rod assemblies 1 of different lengths and splicing them to the effective length according to the distance between the two guide rollers 10 to be adjusted. Utilizing the height difference between the guide rollers 10, the limiting rod 9 is placed behind the higher guide roller 10 near the edge, so that the dial indicator 4 is placed in the middle of the guide roller 10. By adjusting the position of the dial indicator 4, it is brought into slight contact with the lower guide roller 10. The dial indicator 4 is then moved to swing left and right until it reaches its maximum value. The reading is then taken and recorded. After recording, the distance on the other side of the guide roller 10 is measured. After the measurement is completed, the fixture remains stationary, and the data is compared with the first measurement. During the adjustment process, the dial indicator 4 can display the measured distance in real time. The adjustment is stopped when the data is the same as the first measurement, and the debugging is completed.
