Detailed Embodiments
[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Please refer toFigures 1 to 4 , the present utility model proposes a temperature calibration module 10, which is used to be installed on the temperature calibration tooling of the battery component capacitance equipment.
[0031] The temperature calibration module 10 includes a heat preservation housing 100 and a heat conduction component. A heat preservation cavity 110 is formed inside the heat preservation housing 100; the heat conduction component is arranged in the heat preservation cavity 110, and the heat conduction component has a first temperature collection groove 220 and a second temperature collection groove 320 arranged oppositely. The bottom surface of the first temperature collection groove 220 can be in thermal conduction contact with the needle bed probe, and the bottom surface of the second temperature collection groove 320 can be in thermal conduction contact with the tooling probe 500; a heating sheet 400 is clamped inside the heat conduction component, and the heating sheet 400 is used to heat the heat conduction component, and the heating sheet 400 is located between the bottom surface of the first temperature collection groove 220 and the bottom surface of the second temperature collection groove 320.
[0032] Specifically, the heat preservation housing 100 can be made of heat preservation materials, with good heat insulation inside to reduce the influence of the environment on the temperature of the heat conduction component. The needle bed probe can be inserted into the first temperature collection groove 220 until the needle bed probe contacts the bottom surface of the first temperature collection groove 220 for heat conduction. The tooling probe 500 can be inserted into the second temperature collection groove 320 until the tooling probe 500 contacts the bottom surface of the second temperature collection groove 320 for heat conduction. When the heating sheet 400 generates heat, it can conduct the heat to the heat conduction component, so that the temperature of the heat conduction component rises to a preset temperature, and the heat conduction component transfers the heat to the needle bed probe and the tooling probe 500 arranged oppositely up and down, realizing the temperature calibration of the needle bed probe. In the temperature calibration module 10 of the present utility model, since the heating sheet 400 is located between the bottom surface of the first temperature collection groove 220 and the bottom surface of the second temperature collection groove 320, and the needle bed probe and the tooling probe 500 are arranged oppositely up and down with respect to the heating sheet 400. Compared with the traditional temperature calibration module 10, in the temperature calibration module 10 of the present utility model, the distance between the heating sheet 400 and the tooling probe 500 and the needle bed probe is closer, so that the heat diffusion of the heating sheet 400 is fast, the tooling probe 500 and the needle bed probe are heated more evenly and concentratedly, reducing the errors of the needle bed probe and the tooling probe 500 and improving the calibration accuracy.
[0033] Please refer to Figure 1 , Figure 3 and Figure 4, Further, the bottom surface of the first temperature collection groove 220 and the bottom surface of the second temperature collection groove 320 are symmetric about the heating sheet 400. In this way, the distance between the heating sheet 400 and the tooling probe 500 is equal to the distance between the heating sheet 400 and the bed of needles probe, and the heat transfer distance of the heating sheet 400 is the same, so that the temperature collection environments of the tooling probe 500 and the bed of needles probe are consistent. At the same time, in order to improve the calibration accuracy, the distances between the heating sheet 400 and the tooling probe 500 and the bed of needles probe can be set as small as possible, so that the distance between the heating element and the tooling probe 500 or the bed of needles probe is closer, the heat is more concentrated, and the possibility of temperature error generated when the heating sheet 400 transfers heat through the heat conduction component is reduced, thereby improving the calibration accuracy.
[0034] Further, the heat conduction component includes a first heat conduction block 200 and a second heat conduction block 300. The first heat conduction block 200 and the second heat conduction block 300 are both arranged in the heat preservation cavity 110. The first heat conduction block 200 has a first temperature collection groove 220, and the second heat conduction block 300 has a second temperature collection groove 320; a first side groove 210 is arranged on the first heat conduction block 200, and a second side groove 310 is arranged on the second heat conduction block 300. The first side groove 210 and the second side groove 310 can be spliced to form a receiving groove 301, and the heating sheet 400 is arranged in the receiving groove 301. Specifically, during assembly, the first heat conduction block 200 and the second heat conduction block 300 are spliced to clamp the heating sheet 400 in the first side groove 210 and the second side groove 310. The first heat conduction block 200 and the second heat conduction block 300 can be connected and fixed by bolts or other connecting parts. At this time, when the heating sheet 400 generates heat, it can conduct the heat to the first heat conduction block 200 and the second heat conduction block 300, so that the temperatures of the first heat conduction block 200 and the second heat conduction block 300 rise to a preset temperature. The first heat conduction block 200 and the second heat conduction block 300 respectively transfer the heat to the bed of needles probe and the tooling probe 500, realizing the temperature calibration of the bed of needles probe. In this way, the assembly process of the temperature calibration module 10 is simple, the structure is simple, and it is easy to implement.
[0035] Further, the materials of the first heat conduction block 200 and the second heat conduction block 300 are copper blocks. By using the characteristic that copper has good heat conduction performance, the heat generated by the heating sheet 400 is transferred into the first heat conduction block 200 and the second heat conduction block 300, realizing the temperature collection of the tooling probe 500 and the bed of needles probe.
[0036] Please refer to Figure 3 and Figure 4 , Further, the shapes of the first side groove 210 and the second side groove 310 are the same. It is convenient to set the distances between the heating sheet 400 and the bed of needles probe and the tooling probe 500 to be closer to contact the first heat conduction block 200 and the second heat conduction block 300 respectively, thereby improving the calibration accuracy.
[0037] Please refer to Figure 1 , Figure 3 andFigure 4 , Further, the shape of the heating sheet 400 is rectangular. The heating sheet 400 should be an axisymmetric figure to ensure that the heating sheet 400 can evenly heat the first heat conduction block 200 and the second heat conduction block 300, and ensure that the temperature measurement environment of the bed of needles probe and the tooling probe 500 is consistent.
[0038] Please refer to Figure 3 and Figure 4 , Further, the heating sheet 400 is connected with an electric wire 410, and the electric wire 410 is used to connect to an external power supply. The heating sheet 400 is heated through the electric wire 410, and the heating sheet 400 generates heat to heat the first heat conduction block 200 and the second heat conduction block 300.
[0039] Please refer to Figure 1 , Figure 3 and Figure 4 , Further, the heat preservation housing 100 includes a heat preservation film 120 and a heat preservation block 130. The heat preservation film 120 is arranged around the outer periphery of the heat preservation block 130, and a heat preservation cavity 110 is formed inside the heat preservation block 130. In this way, the heat preservation film 120 and the heat preservation block 130 can keep the temperature inside the heat preservation cavity 110 stable. The heat of the heat preservation block 130 is separated by the heat preservation film 120, so that the heat of the first heat conduction block 200 and the second heat conduction block 300 cannot be conducted to the external environment, reducing the influence of the external environment on the temperature inside the heat preservation cavity 110 and maintaining a stable temperature measurement environment.
[0040] Please refer to Figure 1 , Figure 3 and Figure 4Furthermore, the thermal insulation shell 100 also includes an upper sealing piece 140, an upper sealing plate 150 and a lower sealing plate 160. The thermal insulation film 120 has an upper opening and a lower opening that pass through the upper and lower parts. The upper sealing piece 140 covers the upper opening, and the lower sealing plate 160 covers the lower opening. The upper sealing plate 150 covers the upper sealing piece 140. A needle bed probe gap 141 is provided on the upper sealing piece 140, and a needle bed probe hole 151 is provided on the upper sealing plate 150. The needle bed probe hole 151, the needle bed probe gap 141, and the first temperature sampling groove 220 are connected to each other. The lower sealing plate 160 is provided with a tooling probe hole 161 that is connected to the second temperature sampling groove 320. In this way, the upper sealing sheet 140, the upper sealing plate 150, the lower sealing plate 160, the insulation film 120 and the insulation block 130 enclose a temperature-stable insulation chamber 110. The needle bed probe slit 141 is set to a slit shape to reduce heat loss and avoid as much as possible the inconsistent temperature sampling environment of the needle bed probe and the tooling probe 500. The needle bed probe hole 151, the needle bed probe slit 141, the first temperature sampling groove 220, the tooling probe hole 161, and the second temperature sampling groove 320 can have the same central axis. The needle bed probe sequentially passes through the needle bed probe hole 151, the needle bed probe slit 141, and the first temperature sampling groove 220 to contact the upper surface of the first heat conductive block 200 for temperature measurement, and the tooling probe 500 sequentially passes through the tooling probe hole 161 and the second temperature sampling groove 320 to contact the lower surface of the second heat conductive block 300 for temperature measurement.
