Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. Based on the embodiments herein, a person of ordinary skill in the art would be able to obtain all other embodiments based on the disclosure herein, which are within the scope of the disclosure herein.
The performance parameters of the laminated battery and the method for detecting the laminated battery are briefly described.
A lithium ion battery is a secondary battery that operates by means of lithium ions moving between a positive electrode and a negative electrode. The laminated cell is a cell manufacturing process for forming a large cell by cutting an anode and a cathode into small pieces and overlapping the small cell with an isolating film to form small cell monomers and then overlapping and connecting the small cell monomers in parallel.
In the production of the laminated battery cell, positive plates, diaphragms and negative plates are sequentially stacked, the number of each plate is certain, the positive plates and the negative plates are required to be aligned and stacked respectively, capacity loss can be caused by the plates with poor alignment, and short circuit risk is increased.
In the projection image of the laminated battery, a positive plate and a negative plate can be displayed, wherein the longer electrode plate is a negative plate, the shorter electrode plate is a positive plate, and the part of the negative plate, which is more than the positive plate, is called a negative redundancy part, namely the distance between the adjacent positive plate and the negative plate. If the distance between the adjacent positive plate and the negative plate is too short, lithium dendrites which can puncture the diaphragm are easy to form, so that thermal runaway is caused, and short circuit is caused; if the distance between the adjacent positive electrode sheet and negative electrode sheet is excessively long, the decrease in battery capacity is liable to occur. Therefore, the distance between the adjacent positive electrode sheet and the negative electrode sheet needs to be within a reasonable range.
In the laminated battery, the length and width of the negative electrode plate must be greater than those of the adjacent positive electrode plate, if the positive electrode plate and the negative electrode plate are dislocated in the stacking process, a certain edge of the positive electrode plate exceeds the edge of the negative electrode plate, lithium precipitation may occur, so that the battery is not uniformly charged locally, and potential safety hazards are caused to the battery.
Therefore, in the production process of the laminated battery, the number of positive plates and the number of negative plates of the battery, the distance between adjacent positive plates and negative plates, the alignment degree and the rotation angle of the positive plates and the negative plates are important performance parameters of the battery. Therefore, in quality inspection of the laminated battery, it is necessary to inspect the above performance parameters.
At present, a linear detection system is adopted to detect the laminated battery, the relative positions of a ray source and a detector in the detection system are fixed, and the included angle between the incident direction of the ray source and the preset edge of the laminated battery is a preset angle. For example, as shown in FIG. 1, in detecting the first corner of the laminated cell, the cell entry may be performed according to (1)>(2) Battery rotation->(3) Angle correction and distance measurement>(4) And the battery moves linearly, and the step of collecting images is performed for detection. Specifically, in the laminated cell entering the detection range and moving to a 1 When the laminated battery is rotated to the angular point position of the first detection angular point, the angle between the incident direction of the ray source S and the preset edge of the laminated battery has a certain deviation from the preset angle (such as 45 degrees), and the angular point position needs to be adjusted. Then the laminated cell is controlled along a 2 To A 3 Is moved to A 3 When the method is used, edge detection and angle correction can be performed by using a visible light camera, so that an included angle between the incident direction of the ray source S and the preset edge of the first corner point of the laminated battery is a preset angle, and the vertical distance from the central point of the ray source S to the first corner point of the laminated battery is measured. Then control the lamination type battery along A 3 To A 2 The ray source S scans the laminated battery, the detector D acquires the projection image of the laminated battery until the laminated battery moves to A 2 . The image processing device can perform image processing on the plurality of projection images of the first corner point acquired by the detector D to obtain a battery image of the first corner point of the laminated battery, and further finish detection of the first corner point of the laminated battery, wherein a point O is an intersection point of a connecting line between the ray source S and the detector D and a moving route of the laminated battery.
Next, the second corner of the laminated cell is inspected, as shown in FIG. 2, and the cell can be rotated according to (5)>(6) Angle correction and distance measurement>(7) The battery moves linearly and acquires images->(8) The step of battery exit is detected. Specifically, after the laminated battery moves to A 2 Then, the control device controls the laminated battery to rotate 90 degrees, namely to rotate to the corner position of the second corner to detect the second corner, and controls the laminated battery to follow A first 2 To A 3 Is moved to A 3 And (3) performing edge detection and angle correction by using a visible light camera, so that an included angle between the incident direction of the ray source S and a second preset edge of the laminated battery is a preset angle (such as 45 degrees), and simultaneously measuring the vertical distance from the central point of the ray source S to the second corner point of the laminated battery. Then control the lamination type battery along A 3 To A 2 The ray source S scans the laminated battery, the detector D acquires the projection image of the laminated battery until the laminated battery moves to A 2 . The image processing device can perform image processing on the plurality of projection images of the second corner point acquired by the detector D to obtain a battery image of the second corner point of the laminated battery, and further finish detection of the second corner point of the laminated battery. After finishing the detection of two corner points of the laminated battery, the laminated battery can be manufactured from A 2 Move to A 1 From A 1 And (5) exiting the detection range to finish the detection of the laminated battery. The point O is the intersection point of the connecting line between the ray source S and the detector D and the moving route of the laminated battery.
In the above detection process, the position for adjusting the corner position of the laminated battery and the position for detecting the laminated battery are the same, and thus, the adjustment of the corner position of the laminated battery and the detection of the laminated battery cannot be performed simultaneously. For example, the detection system detects a plurality of laminated batteries (battery n, battery (n+1) … … battery (n+k)), and it is necessary to adjust the corner positions of the corner points to be detected of the laminated batteries first, and then detect the corner points to be detected.
As shown in fig. 3, the detecting station and the adjusting station are one, and according to the time sequence, the control device adjusts the position of the n-corner 1 of the battery, then detects the n-corner 1 of the battery, adjusts the position of the n-corner 2 of the battery, then detects the n-corner 2 of the battery, and then adjusts … … the position of the n-corner 1 of the battery (n+1) until the detection of the n-corner 2 of the battery (n+k) is completed. When carrying out the angular point position adjustment to the angular point of lamination formula battery like this, the removal of lamination formula battery, rotation, angular deviation correction all need certain time, and distance measurement or distance correction etc. also need certain time like this, lead to radiation source and detector work to pause, have influenced the detection speed of lamination formula battery, and then lead to lamination formula battery's detection efficiency low.
Therefore, in order to increase the detection speed of the laminated battery and further improve the detection efficiency of the laminated battery, the embodiments of the present application provide a detection method, a device, a detection system, a control device, a computer readable storage medium and a computer program product of the laminated battery. The following first describes a method for detecting a laminated battery according to an embodiment of the present application.

wherein the second detection bit is a next detection bit of the first detection bit in a first direction of movement of the first laminated battery.
It can be seen that, in the solution provided in the embodiment of the present application, after the first laminated battery reaches the first detection position and the first battery detection operation is completed, the control device may control the first laminated battery to move to the second detection position, and in the process of controlling the first laminated battery to move to the second detection position, control the second laminated battery to move to the first detection position at the same time, so as to perform the first battery detection operation on the second laminated battery at the first detection position, and/or, after the first laminated battery reaches the first detection position, the control device continuously controls the first laminated battery to move to the second detection position, and in the process of controlling the first laminated battery to move to the second detection position, control the second laminated battery to move to the first detection position at the same time, so as to trigger the start or end of the first battery detection operation for the second laminated battery after the second laminated battery reaches the first detection position. Therefore, when one laminated battery is controlled to move from one detection position to another detection position, the other laminated battery can be controlled to move to the first detection position to perform corresponding detection operation, detection of the next laminated battery of the laminated battery is not needed after detection of the laminated battery is completed, the moving time of the laminated battery is fully utilized, the detection speed of the laminated battery is accelerated, and the detection efficiency of the laminated battery is further improved.
In step S501, if there is a corresponding first battery detection operation on the first detection position, the control device may control the first laminated battery to move to the second detection position after the first laminated battery reaches the first detection position and the first battery detection operation is completed. The first battery detection operation may be an adjustment operation or an angular point image acquisition operation. The first detection bit may be used as an adjustment station if the first battery detection operation is an adjustment operation; if the first battery detection operation is a corner image acquisition operation, the first detection position can be used as a detection station, namely, a projection image of a corner to be detected of the laminated battery can be acquired at the detection position.
In step S502, in the process of controlling the first laminated battery to move to the second detection position by the control device, the second laminated battery may be simultaneously controlled to move to the first detection position to perform the first battery detection operation on the second laminated battery at the first detection position. The second laminated battery is the next laminated battery to be detected of the first laminated battery. The second detection bit is the next detection bit to the first detection bit in the first direction of movement of the first laminated battery. That is, the control device may control the movement of the second laminated battery while controlling the movement of the first laminated battery to complete the first battery detection operation when the second laminated battery moves to the first detection position. The step length in the movement process of the laminated battery can be set according to practical situations, and is not particularly limited herein.

And in the process that the control equipment controls the first laminated battery to move to the second detection station, simultaneously controlling the second laminated battery to move to the first detection station so as to acquire a plurality of projection images of the corner points to be detected of the second laminated battery, which are acquired by the detector.

And in the process that the control equipment controls the first laminated battery to move to the adjustment station, simultaneously controlling the second laminated battery to move to the detection station so as to finish the acquisition of a plurality of projection images of the corner points to be detected of the second laminated battery.
In step S601, if the first detection position is a position for triggering the start or end of the first battery detection operation, the control device may continue to control the first laminated battery to move to the second detection position after the first laminated battery reaches the first detection position.
The control device may simultaneously control the movement of the second laminated battery to the first detection position during the process of controlling the movement of the first laminated battery to the second detection position, so as to trigger the start or end of the first battery detection operation for the second laminated battery after the second laminated battery reaches the first detection position, that is, execute step S602. Wherein the second detection bit is a next detection bit along the first detection bit in the first direction of movement of the first laminated battery.
