Background
At present, the soft package battery is widely applied to electric automobiles and various electronic products, and the battery pack is manufactured by utilizing the soft package battery, so that the battery pack with proper capacity can be conveniently obtained, and the soft package battery is conveniently applied to different products. The plastic-aluminum membrane has good ductility, so wide application in making laminate polymer battery, but the plastic-aluminum membrane texture is softer, is easily by the fish tail, leads to laminate polymer battery to reveal, influences product quality and safe in utilization. In placing the stereoplasm casing with laminate polymer battery, if the aluminum hull, make into the battery module, be favorable to playing the guard action to laminate polymer battery, assemble and operate in the production process of being convenient for to quantity through adjusting laminate polymer battery can conveniently adjust the capacity of single battery module, and according to the product that will use, come to make up a plurality of battery modules.
When the preparation battery module, need pack the battery into the casing with soft package, during this process of shell is gone into to electric core, very strict to the position required precision of the equipment of electric core and casing, can often make the problem that electric core card shell appears in the actual production process because of the skew of electric core and shell position, light messenger produces the line and shuts down the maintenance, then probably hits the electric core and goes into shell equipment and make whole battery produce the line and stop the pendulum.
The method of soft-package battery cell income aluminum hull among the prior art is directly put the aluminum hull in the appointed tool, adsorbs the soft package of supplied materials again, utilizes the manipulator to transport established position, then pushes down soft-package battery cell and reaches the effect of going into the aluminum hull. Electric core does not have the position of accurate detection shell before going into the shell, and just the position of having relied on the tool determines the position of shell, in case the supplied materials position of electric core changes, perhaps the blowing position of aluminum hull changes, will lead to electric core to go into can not inside the aluminum hull, error when the equipment appears, for example the blank pressing, crush the aluminum hull when will leading to soft-package electric core to push down, lead to soft-package electric core to go into the unusual condition of aluminum hull, damage the product, influence the assembly precision of electric core and shell, the yields and the production efficiency of battery are reduced.
In order to improve the assembly precision of the battery cell and the shell, a shell entering device and a shell entering method of the battery cell and the shell are disclosed in the patent application document with the prior art publication number of CN110854421A, wherein the shell entering device comprises a jig, a fixing groove is arranged on the jig, and the shell entering device further comprises a battery cell detection platform, a battery cell position visual detection device, a shell position visual detection device, a transfer adjustment mechanical arm and an electric control cabinet; the cell position visual detection device is arranged above a cell detection station of the cell detection platform; the shell position visual detection device is arranged above a shell detection station of the fixed groove, and a light supplement device for supplementing light to the shell is arranged on the periphery of the shell detection station; the transferring and adjusting manipulator is arranged between the battery cell detection station and the shell detection station; the input end of the electric control cabinet is electrically connected with the cell position visual detection device and the shell position visual detection device, the output end of the electric control cabinet is electrically connected with the transfer adjustment manipulator, the shell entering method uses the shell entering device, visual detection comparison is carried out on the positions of the cell and the shell in the shell entering process, then the cell is accurately placed into the shell according to the comparison result by using the transfer adjustment manipulator, and therefore the assembly precision of the cell and the shell is improved.
According to the technical scheme, when the positions of the shell and the battery cell are visually detected, reference points are respectively selected from the shell and the battery cell to determine the positions of the shell and the battery cell, then the position of the battery cell is adjusted to enable the coordinate of the reference point of the battery cell to coincide with the coordinate of the reference point of the shell, the battery cell is placed into the shell, and the preferred reference points are respectively the central points of the shell and the battery cell. According to the technical scheme, when the shell is formed by the battery cell, the position of the shell and the position of the battery cell are started, and then the position of the battery cell is adjusted according to the position of the shell, so that the shell is formed. However, in the actual detection process, because the main bodies of the casing and the battery cell are both in a square structure, the center position of the battery cell coincides with the center position of the casing, but the angle between the battery cell and the casing has a deviation. Therefore, the technical solution still has a limited effect on improving the assembly accuracy of the battery cell and the housing.
Therefore, it is urgently needed to develop a visual inspection method for increasing the success rate of the soft package battery cell entering the case, so as to further improve the assembly precision of the battery cell and the case, reduce the production cost and improve the yield and the production efficiency of the battery production.
