Embodiment 1
[0036] Such as figure 1 As shown, an automatic deviation correction method for battery pole piece protective glue comprises the following steps:
[0037] Step 1: According to the battery process requirements, set the collection items and corresponding standard parameters;
[0038] Step 2: Before the pole piece is coiled, image acquisition is performed on the pole piece to be inspected;
[0039] Step 3: According to the image of the pole piece to be inspected, collect and analyze the position parameters of the protective glue, and then judge whether the protective glue has shifted according to the analysis results. Make adjustments.
[0040] It should also be explained that in the deviation correction method of the present invention, in step 1, since there are many types of batteries, different types of batteries adopt different ways of pasting protective glue, resulting in changes in the collection items and corresponding standard parameters. The user needs to set the colle...
Embodiment 2
[0053] Such as figure 1 As shown, a device for realizing the automatic deviation correction method of the above-mentioned battery pole piece protective glue, including:
[0054] The image sensor is used for image acquisition of the pole piece to be inspected and the position parameters of the protective glue;
[0055] The micro-control module is used to receive position parameters, analyze the position parameters, determine whether the protective glue is offset, and adjust the position of the protective glue to be attached to the pole piece.
[0056] Preferably, the image sensor is arranged above the film making machine. It is installed above the film making machine to facilitate the image collection of the battery pole piece in the transmission direction. At the same time, it is fixed at the same position, which can reduce the error of image collection and improve the accuracy of collection.
[0057] Preferably, the image sensor is in communication connection with the micro...
Embodiment 3
[0061] The difference from Example 1 is that the model of the battery in this example is 396074 battery. According to the technical requirements of the battery, such as: set the collection items as the size of the protective glue exposed in the width direction of the pole piece, the protective glue to the edge of the pole piece coating area The corresponding standard parameters are 0.8mm and 24mm;
[0062] It is found that the protective glue is exposed at the left end of the pole piece by 1.0mm, and the protective glue is exposed at the right end of the pole piece by 0.6mm. Since the standard parameter is 0.8mm, just move the protective glue to the right end by 0.2mm to meet the requirement;
[0063] Now collect a set of distances from the protective glue to the edge of the pole piece coating area for analysis, such as
[0064] 24.14 24.13 24.13 24.07 24.12
[0065] 24.19 24.13 24.16 24.20 24.14
[0066] The calculated average value is 24.14, the standard parameter is 24mm...
