1-3, in the power battery gluing method provided by the embodiment of the present application, a gluing route is designed corresponding to a gluing area of a battery to be glued, and the gluing route can be designed along the length direction of the module when the gluing route is designed; therefore, in the early stage of project development, the coating effect of the gluing track and glue and related performance tests, such as parameters of gluing distance, track, height and the like, are verified through the power battery gluing method, the corresponding power battery gluing device is designed, the gluing guns are used for gluing one by one along the separation columns of the power battery gluing device, the size heights are engraved on the separation columns, and the size heights on the separation columns can be adjusted by referring to the size heights on the separation columns during gluing.
In some implementation scenarios, the power battery gluing method provided by the embodiment of the application can be used for performing gluing quantity calculation, track method and corresponding tool development in the early stage of power battery design and development, including gluing track route, gluing sectional area calculation, gluing interval, gluing number, press-fitting force, surface dryness, discharge rate and corresponding gluing tool; optionally, the specific flow steps of the power battery gluing method are as follows:
step 1, determining a gluing track route of a battery to be glued, wherein the gluing track route can be along the length direction of a module/an electric core;
step 2, calculating gluing intervals and gluing number:
if the gluing area is 758x304mm, setting the gluing section to be a semicircle with the diameter of 8mm according to the pipe diameter of the front end rubber pipe of the gluing gun and the control of the ejection time, calculating the number of the rubber strips to be 21 and the distance between the rubber strips to be 6mm, wherein the distance between the most peripheral edges of the rubber strips is 5 mm. The theoretical glue spraying height is 1.2mm according to the design of the product;
step 3, calculating the required glue beating amount:
and calculating the required capacity and volume according to the cross section and the height of the adhesive tape. The required weight of the glue is then initially assessed for purchase based on the glue density supplied by the supplier, e.g. 2g/cm 3. The current period of the general item is purchased according to a certain percentage (such as 25%) of the calculated glue weight, because the actual glue is distinguished according to the actual flatness of the product;
step 4, checking the press fitting force:
the glue is actually measured to be pressed to a pressure of 1mm at a certain thickness, for example, the torque of a module mounting bolt is compared to convert the pressure, and the feasibility of press mounting is judged by comparing the size of the glue with the size of the glue; by checking the press-fitting force, whether the viscosity of the glue is too high or not can be recognized in advance, and whether the press-fitting is successful or not can be recognized;
step 5, actually measuring the flatness between the water-cooling plate and the cell module:
the actual flatness is calculated by using the plasticine with the original thickness of 2.5mm, placing the plasticine on each place on the water cooling plate, using the module for normal installation and assembly, taking out the module, and testing the thickness of the plasticine. Then, the glue coating thickness is adjusted;
step 6, gluing and keeping watch dry time in mind:
once the glue is dried, the glue is not adhered, the surface drying time of the general heat conduction structural glue at normal temperature is more than 25 minutes, and the time for gluing the glue for staff operation is generally controlled to be less than 20 minutes, so that the glue is relatively safe. The ejection rate of the glue gun is limited, for example, the ejection rate is 80g/s, the time required for the weight of the needed glue to be completely beaten is needed to be calculated in the early stage, and if the time exceeds the surface drying time, a plurality of glue guns are needed to be simultaneously carried out;
by calculating the discharge rate and the surface drying time in advance, the insufficient number of the glue guns can be identified, the glue guns can be purchased in advance, and the occurrence of glue coating failure caused by glue coating surface drying is avoided;
step 7, test verification:
after the glue is applied, the overflow condition of the periphery of the module is attended to, the module is taken out for a period of time to check the coating condition, and the gluing process and parameters are adjusted if necessary.
By way of example, the embodiment of the application designs a set of feasible gluing method by calculating various parameters of the power battery gluing, such as a gluing route, a track, a gluing amount, a press fitting force and the like, and designs and makes a gluing tool according to the parameter method so as to coat the heat-conducting structural glue between the power battery water cooling plate and the module/electric core, shorten the project development period and improve the gluing efficiency, and provide the prior parameter input and glue model selection and verification for automatic gluing of a machine in a mass production stage.
