Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a length detection device for a solid-state battery. Background Art

[0002] The production of solid-state batteries, especially power batteries used to drive new energy vehicles, has increased sharply. For larger automotive power batteries, an important inspection item before leaving the factory is to detect their length. Length detection is not only related to the safety of the power battery pack, but also involves the overall assembly quality of the power battery pack. Manual length detection is not only time-consuming and labor-intensive but also prone to errors. Based on this, it is necessary to design a device to detect the length of solid-state batteries. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a length detection device for solid-state batteries in view of the deficiencies of the above-mentioned prior art. The device has a scientific and reasonable structural design, simple operation, accurate detection, high detection efficiency, low labor cost, and can be promoted for use.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a length detection device for solid-state batteries, characterized in that it includes a workbench, a conveyor belt and a distance sensor, the conveyor belt is installed on the workbench, side baffles are installed on the workbench at positions on both sides of the conveyor belt, a plurality of plug-in slots are equidistantly provided on the conveyor belt, and limit plates are movably plugged in the plug-in slots, and a fixed area for fixing the solid-state battery is formed between adjacent limit plates. The distance between the two limit plates in the fixed area is equal to the width of the solid-state battery, and a pair of distance sensors are correspondingly arranged on the side baffles, the plug-in slots are perpendicular to the sides of the conveyor belt, and adjacent plug-in slots are arranged in parallel to ensure that the limit plates are parallel to each other, and to ensure that the solid-state battery clamped therein is always in a state perpendicular to the side baffles, and the solid-state battery clamped between the limit plates keeps its long side perpendicular to the side baffles.

[0005] Preferably, the distance sensor is a photoelectric distance sensor. The distance between a pair of distance sensors arranged opposite to each other is simultaneously measured by the terminal computer, and the distance between the distance sensor and the solid-state battery is obtained by subtracting the values ​​measured by the two distance sensors from the fixed-size side baffle spacing to obtain the accurate length of the solid-state battery. The value measured by the distance sensor used is the minimum value obtained.

[0006] Preferably, the conveyor belt is driven by a conveyor motor.

[0007] Compared with the prior art, the utility model has the following advantages:

[0008] 1. The utility model detects the distance from the sensor to the side of the solid-state battery through the photoelectric distance sensor, thereby obtaining the length dimension of the solid-state battery from the fixed dimension. The detection method is reasonable and reliable, and the detection accuracy error is small.

[0009] 2. The utility model can set the spacing of the plug-in slots according to the common solid-state battery sizes. When detecting solid-state batteries of different sizes, a suitable plug-in method can be selected to provide a fixing area of ​​a suitable size. The utility model is flexible and can be promoted for use.

[0017] like Figure 1 and Figure 2 As shown, the utility model includes a workbench 1, a conveyor belt 3 and a distance sensor 6. The conveyor belt 3 is installed on the workbench 1. Side baffles 2 are installed on the workbench 1 at positions on both sides of the conveyor belt 3. A plurality of plug-in slots 8 are equidistantly provided on the conveyor belt 3. Limiting plates 4 are movably plugged into the plug-in slots 8. A fixing area 5 for fixing a solid-state battery 7 is formed between adjacent limiting plates 4. The distance between the two limiting plates 4 in the fixing area 5 is equal to the width of the solid-state battery 7. A pair of distance sensors 6 are correspondingly arranged on the side baffles 2. The plug-in slots 8 are perpendicular to the sides of the conveyor belt. Adjacent plug-in slots 8 are arranged in parallel to ensure that the limiting plates 4 are parallel to each other, and that the solid-state battery 7 clamped therein is always in a state perpendicular to the side baffles 2. The solid-state battery 7 clamped in the limiting plates 4 keeps its long side perpendicular to the side baffles 2.

[0018] In this embodiment, the distance sensor 6 is a photoelectric distance sensor, and the distance sensor 6 is connected to the computer terminal. The distance between the distance sensor 6 and the solid-state battery 7 is simultaneously measured by a pair of distance sensors 6 arranged opposite to each other. The terminal computer obtains the accurate length of the solid-state battery 7 by subtracting the value measured by the two distance sensors 6 from the spacing between the side baffles 2 of a fixed size. The value measured by the distance sensor 6 used is the minimum value obtained.

[0019] In this embodiment, the conveyor belt 3 is driven by a conveyor motor.

[0020] When in use, the solid-state batteries 7 to be tested are placed at intervals in the fixed area 5, and the long sides of the solid-state batteries 7 are clamped by the limit plates 4. When the conveyor belt 3 is running, it drives the solid-state batteries 7 to pass between the distance sensors 6 in sequence. The two distance sensors 6 respectively measure multiple distances from the side edges of the solid-state battery 7, and the maximum values ​​measured by the two distance sensors 6 are taken. The terminal computer calculates the distance between the two side baffles 2 minus the two maximum values. The final reading is the length value of the solid-state battery 7. Multiple values ​​can be measured on a solid-state battery 7 and their average value can be taken.

[0021] The above are only preferred embodiments of the present invention, and do not limit the present invention in any way. Any simple modification, change and equivalent changes made to the above embodiments based on the technical essence of the present invention are still within the protection scope of the technical solution of the present invention.
