Therefore, the flatness and thickness of the square aluminum shell lithium battery are usually detected by a detection device. However, in the related art, the battery to be detected is usually manually carried to a detection station, which not only increases the labor burden of workers, but also leads to low detection efficiency.

[0039] Therefore, the present application provides a detection device, Figure 1 is a structural schematic diagram of the detection device provided by the embodiments of the present application, Figure 2 is Figure 1 is a structural schematic diagram of the detection device (first state) and the battery, Figure 3 isFigure 2 a front view schematic diagram of the detection device, Figure 4 is Figure 1 a structural schematic diagram of the detection device (second state) and the battery, Figure 5 is Figure 4 a top view schematic diagram of the detection device. The detection device provided by the utility model can automatically convey the battery to the detection station, thereby reducing the burden of the laborer and improving the detection efficiency. The detection device will be described in detail below in combination with the main drawings.

[0040] Referring to Figures 1 to 3 , the detection device 10 comprises a base 1, a bearing conveying part 2 and a detection assembly, the base 1 is provided with a detection station, the bearing conveying part 2 is used for bearing the battery 20 and is suitable for conveying the battery 20 to the detection station, the battery 20 is provided with two detection surfaces 201 arranged oppositely, the detection assembly is located at the detection station, and the detection assembly comprises two detection parts 31 arranged oppositely along a first direction, and the two detection parts 31 are used for detecting the flatness of the two detection surfaces 201 or the distance between the two detection surfaces 201.

[0041] In the embodiment of the utility model, the bearing conveying part 2 bears the battery 20, and the bearing conveying part 2 can automatically convey the battery 20 to the detection station, so that the trouble of manual carrying is reduced, thereby improving the detection efficiency. The detection assembly is located at the detection station, and the detection assembly comprises two detection parts 31 arranged oppositely along a first direction. The flatness of the two detection surfaces 201 arranged oppositely of the battery 20 or the distance between the two detection surfaces 201 can be detected by the two detection parts 31. The combination of the bearing conveying part 2 and the detection assembly realizes the automatic conveying and automatic detection of the battery 20 detection process, reduces the manual intervention, avoids the production delay or detection error caused by human factors, and improves the detection efficiency and detection accuracy.

[0042] Referring to Figure 2 and Figure 4 , in an embodiment, the bearing conveying part 2 comprises at least two pulleys 21 and a transmission belt 22, the at least two pulleys 21 are arranged at intervals along a second direction, and the second direction is arranged perpendicularly to the first direction. This layout makes the whole bearing conveying part 2 more compact in space, which is beneficial to saving space. The transmission belt 22 is arranged outside the at least two pulleys 21, so that the at least two pulleys 21 can drive the transmission belt to rotate, so that the straight line segment 221 of the transmission belt 22 arranged along the second direction can keep stable and translate along the second direction, and so that the battery 20 located at the straight line segment 221 can be accurately conveyed to the detection station. The structure of the transmission belt 22 and the pulley 21 is relatively simple, easy to maintain and replace, and when the transmission belt 22 is worn or damaged, only a new transmission belt 22 needs to be replaced, without the need to overhaul the whole bearing conveying part 2.

[0043] It should be noted that the bearing conveying part 2 composed of the belt wheel 21 and the transmission belt 22 is suitable for the conveying needs of various batteries 20, and can sequentially convey multiple batteries 20 to the detection station at a time, so that batch detection of multiple batteries 20 can be realized, which reduces the time and labor cost required for sequentially placing and detecting the multiple batteries 20 in the detection station, and significantly improves the detection efficiency. The continuous conveying characteristics of the transmission belt 22 enable the batteries 20 to enter the detection station uninterruptedly, avoiding waiting and delay in the production process, and further improving the detection efficiency.

[0044] In other embodiments, the bearing conveying part 2 can also include a chain conveying line or an AGV (Automatic Guided Vehicle) conveying system. The chain conveying line is composed of a chain and a chain wheel, and the battery 20 carrier is fixed on the chain. The battery 20 is placed on the carrier, and the conveying of the battery 20 is realized through the circulating movement of the chain. The AGV (Automatic Guided Vehicle) conveying system is composed of an AGV, a battery 20 carrier, a navigation system, etc. The AGV can automatically travel according to the preset route, and convey the battery 20 carrier from one station to another station. Specifically, the type of the bearing conveying part 2 can be selected as needed, and the present application does not limit it.

[0045] Referring to Figures 3 to 5 In an embodiment, the detection device 10 further comprises a limiting part 4, which is installed on the bearing conveying part 2. The limiting part 4 limits the vertical placement of the battery 20, avoiding detection errors caused by shaking or tilting of the battery 20. Two detection surfaces 201 are arranged in the thickness direction of the battery 20. Thus, since the area of the detection surface 201 arranged in the thickness direction of the battery 20 is usually larger than the area of the other side of the battery 20, the detection surface 201 will abut against the test platform when the battery is placed horizontally. When the detection surface 201 has a protrusion, the center of gravity of the horizontally placed battery 20 will be offset, causing part of the position to be raised, and the measured value of the battery 20 is prone to error. In the present application, the battery 20 is vertically placed. Since the bottom plane of the battery 20 is small, even if there is a protrusion at the bottom of the battery 20, the influence of the protrusion on the offset of the center of gravity of the battery 20 is small, reducing the measurement error caused by the protrusion, tilting or tilting of the battery 20. Vertical placement also helps to reduce the influence of gravity on the shape of the battery 20, making the measurement result more accurate.

[0046] Referring to Figure 5In an embodiment, the limiting part 4 comprises a limiting main body 41 and at least two limiting platforms 42. The limiting main body 41 is installed on the bearing conveying part 2. The limiting main body 41 is used to abut against the bottom of the battery 20, thereby providing stable bottom support for the battery 20, preventing the battery 20 from shaking or tilting during the conveying process. The at least two limiting platforms 42 are installed on the limiting main body 41. The at least two limiting platforms 42 are used to abut against the two opposite side walls of the battery 20, thereby further preventing the battery 20 from toppling over during the conveying process, thereby enhancing the stability of the battery 20 during the conveying process. Through the combined action of the limiting main body 41 and the limiting platforms 42, the battery 20 is stably in a vertical state, thereby facilitating subsequent detection of the two detection surfaces 201 of the battery 20.

[0047] In other embodiments, the at least two limiting platforms 42 can also be movably connected with the limiting main body 41, so that the distance between the at least two limiting platforms 42 is adjustable. Thus, the limiting part 4 is suitable for limiting different sizes of batteries 20, and ensures that the battery 20 of the corresponding size is stably in a vertical state. Thus, the detection device 10 can detect batteries 20 of different sizes, thereby improving the versatility of the detection device 10.

[0048] Referring to Figure 2 and Figure 4 In an embodiment, a positioning assembly is further arranged between the limiting part 4 and the bearing conveying part 2. The positioning assembly comprises a positioning part 51 and a cooperating part 52 matched with the positioning part 51. One of the positioning part 51 and the cooperating part 52 is arranged on the bearing conveying part 2, and the other is arranged on the limiting part 4. In this way, the positioning part 51 and the cooperating part 52 ensure accurate positioning between the limiting part 4 and the bearing conveying part 2. This accurate positioning method helps to reduce misalignment of the limiting part 4 relative to the bearing conveying part 2. Through the fixing action of the positioning assembly, the connection between the limiting part 4 and the bearing conveying part 2 is more stable, which helps to prevent loosening or displacement due to vibration or external force during the conveying of the battery 20, thereby improving the overall stability. Due to the accuracy and stability of the positioning assembly, excessive adjustment and calibration are not required during assembly. This reduces the time required for assembly and improves detection efficiency.

[0049] It should be noted that there are many types of positioning parts 51 and cooperating parts 52. For example, in an embodiment, one of the positioning part 51 and the cooperating part 52 can comprise a positioning protrusion, and the other can comprise a positioning groove. Of course, in other embodiments, the positioning part 51 and the cooperating part 52 can also comprise a magnetic part and a magnetic part cooperating part 52, and the magnetic part and the magnetic part cooperating part 52 are arranged to be different in magnetic properties. Specifically, the types of the positioning part 51 and the cooperating part 52 can be set as needed, and the present application does not limit them.

[0050] Referring to Figure 1 andFigure 2 In an embodiment, the detecting unit 31 comprises a mounting body 311 and a detecting body 312, the mounting body 311 is mounted on the base 1, the mounting body 311 has a mounting side for being arranged opposite to the detecting surface 201, the detecting body 312 comprises a movable piece 3121 and a sensor 3122, the movable piece 3121 is movably mounted on the mounting side along the first direction, the movable piece 3121 is used to abut against the detecting surface 201, the sensor 3122 is mounted on the movable piece 3121, the displacement of the movable piece 3121 is detected by the sensor 3122, and the flatness of the two detecting surfaces 201 or the distance between the two detecting surfaces 201 can be measured based on the displacement.

[0051] It should be noted that the sensor 3122 can comprise a laser ranging sensor 3122 or an inductive displacement sensor 3122. The type of the sensor 3122 can be selected as needed, which is not limited in the present application.

[0052] Referring to Figure 4 and Figure 5 In an embodiment, the sensor 3122 is mounted on one end of the movable piece 3121 away from the mounting body 311, and the movable piece 3121 abuts against the detecting surface 201 through the sensor 3122, so that the sensor 3122 can accurately perceive the slight change of the detecting surface 201, and this mounting manner reduces the transmission error between the sensor 3122 and the movable piece 3121, thereby improving the accuracy of the entire detection.

[0053] Referring to Figure 2 and Figure 3 In an embodiment, the detecting unit 31 further comprises a first driving assembly 313, the first driving assembly 313 comprises a first driving body 3131 and a first driving shaft 3132, the first driving body 3131 is mounted on the base 1, the first driving shaft 3132 has a movable stroke along the first direction relative to the first driving body 3131, and the first driving shaft 3132 is drivingly connected with the movable piece 3121, so that the first driving shaft 3132 can move accurately along the first direction, which makes the movable piece 3121 move along a predetermined trajectory, and helps to ensure the accuracy of the measurement. The first driving assembly 313 can quickly and accurately drive the movable piece 3121 to move, thereby shortening the detection time.

[0054] It should be noted that the detecting device 10 further comprises a controller, the controller is electrically connected with the sensor 3122 and the first driving assembly 313, when the sensor 3122 abuts against the detecting surface 201, the sensor 3122 will emit a signal to the controller, and the controller will stop the first driving assembly 313 from working based on the signal, so as to avoid the first driving assembly 313 from continuing to work, which causes the sensor 3122 to be damaged or the sensor 3122 to bruise the detecting surface 201.

[0055] The first driving assembly 313 can be of various types, for example, the first driving assembly 313 can include an electric push rod, a linear motor, a ball screw, etc. Specifically, in an embodiment, the first driving assembly 313 includes a driving cylinder, the cylinder body of the driving cylinder forms the driving body, and the piston rod of the driving cylinder forms the driving shaft. In this way, the structure of the driving cylinder itself is relatively compact, occupying less space, which helps to realize a more compact layout of the detection part 31. The direct connection of the cylinder body and the piston rod reduces the additional transmission mechanism, making the overall structure simpler. The linear driving force of the cylinder is stable and not easily disturbed by external factors, thereby improving the stability of the movement of the movable part 3121. The structure of the cylinder is relatively simple, easy to maintain and maintain. The cylinder has a low failure rate and is relatively easy to troubleshoot and repair, reducing maintenance costs. The cylinder can adapt to different working environments and conditions, such as high temperature, high pressure, humidity, etc. The stroke and driving force of the cylinder can be adjusted according to actual needs, with strong adaptability. The cylinder usually uses compressed air as a power source, with low energy consumption and emissions. The driving force of the cylinder is usually moderate and is not easy to cause damage to the detection surface 201.

[0056] It should be noted that the type of the first driving assembly 313 can be selected as needed. In addition, in the embodiments of the present application, the detection device 10 further includes an electrical control system, and the cylinder is combined with the electrical control system to realize automatic control. Through programming, the stroke, speed and acceleration of the cylinder can be accurately controlled to meet different detection needs.

[0057] Referring to Figure 2 and Figure 4 In an embodiment, a plurality of detection bodies 312 are arranged at intervals on the mounting side. In this way, by arranging a plurality of detection bodies 312, multi-point detection can be performed, which helps to improve the accuracy of measuring the flatness of the detection surface 201. The interval arrangement of the plurality of detection bodies 312 can reduce the detection blind area. The arrangement of the plurality of detection bodies 312 constitutes a redundant design, when one or more detection bodies 312 fail or have errors, other detection bodies 312 can still provide effective detection data, thereby ensuring the reliability of the overall detection. The plurality of detection bodies 312 can cross-verify the same detection surface 201, by comparing the data of different detection bodies 312, potential errors can be found and corrected, further improving the accuracy of detection.

In addition, the second driving assembly 314 provides additional driving force for the mounting body 311, so that the mounting body 311 can move more accurately and quickly along the first direction.

[0059] In addition, when the first driving assembly 313 fails to drive the movable piece 3121 to move to abut against the detection surface 201, the mounting body 311 is driven to move by the second driving assembly 314, so that the movable piece 3121 mounted on the mounting body 311 moves to abut against the detection surface 201, thereby ensuring that the detection unit 31 can normally detect the flatness of the two detection surfaces 201 or the distance between the two detection surfaces 201.

[0060] It should be noted that the second driving assembly 314 has various types, and in other embodiments, the second driving assembly 314 can also include an electric push rod, a linear motor or a ball screw, etc. Specifically, the type of the second driving assembly 314 can be selected as needed, and the present application does not limit it.

[0061] Referring to Figure 2 and Figure 4 In an embodiment, the detection unit 31 further comprises a guide structure, the guide structure comprises a sliding groove 3151 and a sliding table 3152 matched with the sliding groove 3151, one of the sliding groove 3151 and the sliding table 3152 is arranged on the mounting body 311, and the other is arranged on the base 1, so that the sliding groove 3151 and the sliding table 3152 play a good guiding role, ensuring that the mounting body 311 moves stably and accurately along the predetermined direction on the base 1, and this design reduces the error caused by unstable movement trajectory and improves the detection accuracy. The design of the sliding groove 3151 and the sliding table 3152 simplifies the mounting process of the mounting body 311. Only the sliding table 3152 needs to be inserted into the sliding groove 3151, and the mounting can be completed, which is simple to operate.

[0062] The steps of measuring the flatness of the two detection surfaces 201 of the battery 20 or the distance between the two detection surfaces 201 by the detection device 10 provided in the application are as follows:

[0063] First, the movable parts 3121 of the two detection parts 31 are driven to abut against the two detection surfaces 201 of the standard part of the battery 20, respectively, the two sensors 3122 detect the first displacement of the movable parts 3121 in the process, and the positions of the two movable parts 3121 are initialized and corrected.

[0067] The flatness of the second detection surface 201 = Max(B1…Bn)-Min(B1…Bn);

[0068] The free-state thickness of the N-point position = the thickness of the standard part + An+Bn.

[0069] It should be noted that in the above measurement method, the battery is suitable for various models of square aluminum shell lithium iron phosphate batteries, and the N-point value is adjusted according to specific needs, N=1, 3, 9, 16, etc.
