Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a tooling for measuring the thickness of a sagger. Background Technology

[0002] Currently, the preparation process of battery cathode materials requires sintering the mixed raw materials to induce a solid-state reaction between the active material particles, thereby achieving crystallization, activation, and improved electrical performance. Sintering is the core process in cathode material preparation, and it requires the use of saggers to support the materials. Currently, the tools used to measure the thickness of the sagger bottom in the sintering process are steel rulers and vernier calipers. Multiple tools are required for measurement, and steel rulers are prone to inaccurate measurements due to human factors. This results in significant measurement errors during sagger incoming material inspection, increasing the rate of defective auxiliary materials and affecting normal production line operations. Another method is to break the sagger and measure the bottom thickness, which wastes the sagger and increases production costs. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figure 1-4 The present invention provides a tooling for measuring the thickness of a sagger, comprising a first fixing member 100, which has a first through hole 101 and a second through hole 102 spaced apart. The first scale 200 moves through the first through hole 101; The second scale 300 moves through the second through hole 102; The first scale 200 and the second scale 300 are set in parallel.

[0019] During the test, the first scale 200 is placed inside the sagger, with its end in contact with the bottom of the sagger. The second scale 300 is placed outside the sagger, with its end flush with the bottom surface of the sagger. The bottom thickness of the sagger can be measured at a single point by reading the values ​​on the first scale 200 and the second scale 300 and calculating the difference. After measuring at several other locations, the average of the measurement differences can be calculated to obtain the data on the bottom thickness of the sagger.

[0020] In one embodiment, the first fixing member 100 is provided with a first positioning member 400 for fixing the first scale 200 and the second scale 300, so as to realize the fixing and movement of the first scale 200 and the second scale 300.

[0021] In this embodiment, after the first scale 200 and the second scale 300 are moved to a designated position relative to the first fixing member 400, the first positioning member 400 fixes the first scale 200 and the second scale 300, thereby preventing the first scale 200 and the second scale 300 from easily moving during the measurement process and affecting the accuracy of the measurement data reading.

[0022] In one embodiment, the first positioning member 400 includes a first bolt 401 threadedly connected to the first fixing member 100. One end of the first bolt 401 extends into the first through hole 101 and the second through hole 102, and the first bolt 401 is fixed by the first nut 402.

[0023] In one embodiment, a second fixing member 500 is further provided parallel to and spaced apart from the first fixing member 100. The second fixing member 500 is provided with a third through hole 501 and a fourth through hole 502 that are spaced apart. A first scale 200 moves through the third through hole 501 and a second scale 300 moves through the fourth through hole 502.

[0024] In this embodiment, the second fixing member 500 is set up so that during measurement, the second fixing member 500 is abutted against the top of the sagger, and then the positions of the first scale 200 and the second scale 300 are adjusted. This allows for the simultaneous measurement of the sagger bottom thickness and the height of the outer and inner sides of the sagger, providing more measurement data.

[0025] In one embodiment, the second fixing member 500 is provided with a second positioning member 600 for fixing the first scale 200 and the second scale 300, so as to realize the fixing and movement of the first scale 200 and the second scale 300.

[0026] In this embodiment, after the first scale 200 and the second scale 300 are moved to a designated position relative to the second fixing member 600, the first positioning member 400 fixes the first scale 200 and the second scale 300, thereby preventing the first scale 200 and the second scale 300 from easily moving during the measurement process and affecting the accuracy of the measurement data reading.

[0027] In one embodiment, the second positioning member 600 includes a second bolt 601 threadedly connected to the second fixing member 500. One end of the second bolt 601 extends into the third through hole 501 and the fourth through hole 502, and the second bolt 601 is fixed by the second nut 602.

[0028] In one embodiment, the first scale 200 and the second scale 300 are of the same length, and both the first scale 200 and the second scale 300 have scale lines with opposite scale directions.

[0029] In this embodiment, when measuring the thickness of the sagger, the plane where the sagger is located is used as a reference. A first scale 200 is located inside the sagger, and a second scale 300 is located outside the sagger. The first scale 200 and the second scale 300 each have a top and a bottom. The bottom of the first scale 200 contacts the bottom surface inside the sagger, and the bottom of the second scale 300 contacts the plane where the sagger is located. The tops of both the first scale 200 and the second scale 300 are close to the first fixing member 100, which has a top and a bottom. The bottom side is closer to the sagger, and the top side is further away from the sagger. The second scale 300... The scale direction of 00 continuously increases along the plane of the sagger towards the first fixing member 100, and the scale direction of the first scale 200 continuously increases along the plane of the sagger towards the first fixing member 100. During measurement, by adjusting the upper edge of the first fixing member 100 to be flush with the top of the second scale 300, since the first scale 200 and the second scale 300 have the same length and opposite scale directions, the scale line defined on the upper edge of the first fixing member 100 is the thickness of the bottom of the sagger. The thickness of the sagger can be obtained directly through the first scale 200 without the need for two readings and difference calculations, making the test more convenient.

[0030] In one embodiment, both the first fixing member 100 and the second fixing member 500 are provided with scale lines. This configuration allows the wall thickness of the sagger to be read directly from the scale lines on the first fixing member 100 and the second fixing member 500 while measuring the bottom thickness of the sagger.

[0031] In one embodiment, both the first fixing member 100 and the second fixing member 500 include a first segment 1001 and a second segment 1002, which are connected by a telescopic member 1003. Specifically, the telescopic member 1005 may be a telescopic rod.

[0032] In this embodiment, the distance between the first scale 200 and the second scale 300 can be adjusted by the telescopic component 1003 according to the wall thickness of the sagger during measurement. This ensures that the first scale 200 and the second scale 300 are located on the inner and outer sides of the sagger during measurement, thus adapting to the measurement of saggers of different lengths and wall thicknesses.

[0033] In one embodiment, both the first segment 1001 and the second segment 1002 of the second fixing member 500 are provided with slidable limiting members 1004. Specifically, the limiting member 1004 may be a clamping block, and the sliding limiting member 1004 is fixed by bolts.

[0034] In this embodiment, the limiting member 1004 is configured to connect the first fixing member 100 and the second fixing member 500 to the sagger during measurement, thereby preventing the first scale 200 and the second scale 300 from moving arbitrarily during measurement and affecting data reading, thus improving measurement efficiency.

[0035] In one embodiment, the limiting member 1004 is a groove provided on the first segment 1001 and the second segment 1002 of the second fixing member 500. The thickness of the groove is greater than the wall thickness on the left and right sides of the sagger. The first segment 1001 and the second segment 1002 are respectively provided with a third through hole 501 and a fourth through hole 502. When the groove on the first segment 1001 is to the right of the third through hole 501, the groove provided on the second segment 1002 is to the left of the fourth through hole 502. When the groove on the first segment 1001 is to the left of the third through hole 501, the groove provided on the second segment 1002 is to the right of the fourth through hole 502.

[0036] In this embodiment, by setting grooves on the first segment 1001 and the second segment 1002, the second fixing member 500 can be fixed on the sagger by the grooves, making the measurement process more stable and the limiting structure simpler. By setting the position of the groove and the through hole, it is possible to ensure that one scale is set inside the sagger and one scale is set outside the sagger, so as to achieve high-efficiency testing of the thickness of the bottom of the sagger.

[0037] It should be noted that if the embodiments of this utility model involve directional indicators such as up, down, left, right, front, back, etc., the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicators will also change accordingly.

[0038] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
