Description

Technical Field

[0001] The utility model relates to the technical field of cell detection, in particular to a cell module detection device. Background Art

[0002] The EOL detection station of the cell module refers to the final detection and verification work on the assembled cell module at the end of the cell module production process. At this station, various detection devices and instruments are usually equipped to detect various parameters and performance indicators of the cell module to ensure that it meets the specified quality standards. At the EOL detection station, the detection device contacts the cell module, and internal data of the cell module is obtained through devices such as sensors or probes. These data may include parameters such as the voltage, current, and temperature of the cell, as well as information such as the connection status and packaging integrity of the cell module. The detection device analyzes and compares the obtained data to determine whether the cell module meets the requirements.

[0003] Currently, the detection of cell modules adopts an overall design structure, which detects the selected cell modules. However, for different models of cell modules, it is often inapplicable, and the positions where different models of cells need to contact the probes are also different, and it cannot be compatible with cell modules of different specifications and sizes, resulting in poor versatility and compatibility. If different cell module products are replaced later, it is often necessary to replace the cell detection device again. Content of the Utility Model

[0004] To solve the above technical problems, the utility model utilizes the adjustment of the position of the probe holder on the mounting plate and combines the relative movement of the adjustment block and the probe holder. The specific technical solutions are as follows:

[0005] A cell module detection device includes a mounting plate with detection components. A number of detection components are slidably mounted on the mounting plate along a first direction. The detection component includes a probe holder slidably connected along a second direction, an adjustment block slidably mounted at one end of the probe holder, and a probe mounted on the adjustment block and the probe holder. The first direction and the second direction are perpendicular to each other, and the plane formed by the two is parallel to the mounting plate.

[0006] In the above solution, the plane formed by the first direction and the second direction is parallel to the mounting plate, ensuring that the position adjustment of the probe holder is horizontal with the mounting plate, so as to avoid the probes being disordered or tilted after installation, which affects the detection effect of the probes on the cell. The probe holder and the mounting plate move along the first direction, and the adjustment block moves relatively along the second direction, so that the position of the adjustment probe can be arbitrarily adjusted on the horizontal plane where the cell detection component is located, and corresponding adjustments can be made for different specifications and sizes of cells. The overall adjustment method is simple and the applicable range is wider.

[0007] Preferably, the detecting member further includes a slider fixedly installed on the opposite side of the probe base relative to the probe. The mounting plate is connected with at least one slide rail along the first direction, and the outside of the slide rail slides relative to several sliders. The number of sliders on the slide rail can be selected, removed or increased by oneself to ensure the number of battery cells detected each time and improve the detection efficiency of the battery cells.

[0008] Preferably, a locking hole communicating with the slider is formed in the probe base, and the probe base and the slider can be fixed through a setscrew in the locking hole. It is convenient to disassemble the probe base and the slider from each other. When subsequent probe maintenance or replacement is needed, only the probe base needs to be disassembled from the slider, and there is no need to pull the slider out from the end of the entire slide rail, which improves the convenience of maintenance.

[0009] Preferably, the probe fixed by the probe base is located at one end far from the adjusting block and is fixed to the probe. The fixed probe can locate the detection point at one end of the battery cell, and the battery cell of the adjusting block can be aligned with the detection point of the battery cell, which is convenient for adjustment according to the detection point of the battery cell.

[0010] Preferably, a groove for the adjusting block to slide is formed at one end of the probe base. It ensures that the moving direction of the adjusting block is along the length direction of the probe base, and at the same time avoids the probe from shifting due to the movement of the adjusting block.

[0011] Preferably, a mounting seat arranged along the second direction is installed on the same side of the detecting member as the mounting plate, and the side of the mounting seat facing away from the mounting plate is slidably connected with the slide rail. The top end of the mounting seat is slidably connected with the slide rail, and the distance between the two slide rails can be adjusted, specifically according to the placement position of the battery cells between different columns.

[0012] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects:

[0013] By adjusting the position of the probe base on the mounting plate, the present utility model can adjust the probe to be located at the detection ports of different battery cell modules. At the same time, in combination with the relative movement of the adjusting block and the probe base, the probes at both ends of the probe base move relatively. Since the detection points of different specifications of battery cells are different, the probe can make corresponding adjustments according to the distance between the detection points, increasing the compatibility with different battery cells and improving the applicable range of detecting different specifications of battery cells.

[0018] The following combines the accompanying drawings and specific embodiments to elaborate on the present utility model in detail. Before elaborating on the technical solutions of each embodiment of the present utility model, the nouns and terms involved are explained. In this specification, components with the same name or the same reference numeral represent similar or identical structures, and are for illustrative purposes only.

[0019] As Figure 1 and Figure 2 shown, a cell module detection device includes a mounting plate 1 with a detecting member 5. A plurality of detecting members 5 are slidably mounted on the mounting plate 1 along a first direction. The detecting member 5 includes a probe seat 50 slidably connected along a second direction, an adjusting block 53 slidably mounted at one end of the probe seat 50, and a probe 54 mounted on the adjusting block 53 and the probe seat 50. The first direction and the second direction are perpendicular to each other, and the plane formed by the two is parallel to the mounting plate 1. Among them, the probe seat 50 moves along the first direction relative to the mounting plate 1, and the staff can adjust the positional relationship between multiple probe seats 50, specifically set according to the placement position of the cell. After the position adjustment of the probe seat 50 is completed, the probe seat 50 is positioned. The adjusting block 53 can slide relative to the probe seat 50, and its position can be limited by tightening with a setscrew. The movement of the adjusting block 53 can drive the probe 54 mounted thereon to move, so as to adjust the relative position between the probe 54 on the adjusting block 53 and the probe seat 50, and corresponding adjustments can be made for cells of different specifications and sizes. The overall adjustment method is simple and the applicable range is wider.

[0020] The first direction and the second direction are perpendicular to each other, and the plane formed by the two is parallel to the mounting plate 1, which ensures that the position adjustment of the probe seat 50 is horizontal with respect to the mounting plate 1, so as to prevent the probes 54 from being disordered or tilted after installation, which may affect the detection effect of the probes 54 on the cell.

[0021] As Figure 1 shown, the detecting member 5 further includes a slider 51 fixedly mounted on the side of the probe seat 50 opposite to the probe 54. The mounting plate 1 is connected with at least one slide rail 4 along the first direction, and the outside of the slide rail 4 slides relative to several sliders 51. Among them, the number of slide rails 4 can be set to multiple, and the number is set according to the number of cells. It is preferably two slide rails 4. The number of sliders 51 on each slide rail 4 can be selected by itself, and it can be detachable or increased, and the number is selected according to the number of cells to ensure the number of cells detected each time and improve the detection efficiency of the cells.

[0022] As Figure 2As shown, a locking hole 52 communicating with the slider 51 is formed in the probe base 50. The probe base 50 and the slider 51 can be fixed through a setscrew in the locking hole 52. Among them, the locking hole 52 facilitates the fixation of the probe base 50 and the slider 51, and facilitates the mutual disassembly of the probe base 50 and the slider 51. When subsequent maintenance or replacement of the probe 54 is required, only the probe base 50 needs to be disassembled from the slider 51, and there is no need to pull the slider 51 out from the end of the entire slide rail 4, improving the convenience of maintenance.

[0023] The probe 54 fixed to the probe base 50 is located at one end far from the adjusting block 53 and is fixed to the probe 54. The distance between the probe 54 at one end of the probe base 50 and the probe 54 on the adjusting block 53 is the distance between the two endpoints required for the detection of the battery cell. When detecting different models of battery cells, the probe 54 installed on the probe base 50 can be aligned and positioned with one end of the battery cell. Secondly, by adjusting the adjusting block 53, the battery cell of the adjusting block 53 can be aligned with the detection point of the battery cell, and then the adjusting block 53 can be locked with a setscrew.

[0024] As Figure 2 shown, a groove for the sliding of the adjusting block 53 is formed at one end of the probe base 50. The groove facilitates the limitation of the adjusting block 53, ensures that the moving direction of the adjusting block 53 is along the length direction of the probe base 50, and at the same time avoids the deviation of the probe 54 of the adjusting block 53 due to its movement, affecting the detection of the battery cell.

[0025] As Figure 1 shown, an installation seat 3 arranged along the second direction is installed on the same side of the installation plate 1 as the detection member 5. The side of the installation seat 3 facing away from the installation plate 1 is slidably connected to the slide rail 4. Among them, the top end of the installation seat 3 is slidably connected to the slide rail 4, and the distance between the two slide rails 4 can be adjusted, specifically set according to the placement positions of the battery cells between different columns.

[0026] As Figure 1 and Figure 3 shown, a handle 2 is arranged at one end of the installation plate 1. The handle 2 helps the staff to grab and drive the entire device to contact the detection point of the battery cell after grabbing.

[0027] A scale is installed on the side wall of the slide rail 4. The setting of the scale can provide the moving position for the slider 51 to achieve compatible detection of different modules.

[0028] A wire groove 6 is arranged on one side of the slide rail 4. The wire groove 6 can be made of PVC material, and equidistantly arranged holes are formed on it. The holes can place the cables of the probe 54, avoiding the interference between the probe wires 54 and the mechanism and improving the use safety.

[0029] When the utility model is in use, the whole device is placed on the vertical guide rail, and the mounting plate 1 slides on the guide rail. After the battery cell module is placed neatly, it is located directly below the device. Secondly, the staff holds the handle 2 and drives the mounting plate 1 to move downwards. The mounting plate 1 drives the detecting member 5 to move downwards, so that the probe 54 contacts the detection point of the corresponding battery cell, realizing the detection of the parameter information of the whole battery cell at one time. When different specifications of battery cells are used in combination, only the adjusting block 53 corresponding to the battery cell needs to be adjusted according to the placement position of different battery cells to ensure that the two probes 54 can contact the detecting member 5 of the battery cell, and the detection of different specifications of battery cells can be realized, with a wide range of applications.

[0030] The above-described embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
