In one embodiment, before the front-side gluing step and the back-side gluing step, an activation treatment step is included: the surface of the upper cover plate 1 is subjected to activation treatment, oil stains and rust stains on the surface of the upper cover plate 1 are removed, the bonding force of the foaming adhesive and the upper cover plate 1 is improved, and the coated foaming adhesive is more uniform and attractive.
In one embodiment, during the front gluing step, the upper cover plate 1 is controlled by the movement device to move relative to the fixed gluing gun for gluing. In the concrete scheme, the moving device centre gripping is in the 1 back of upper cover plate, and drive upper cover plate 1 removes for fixed glue gun along the rubber coating route, and fixed glue gun is fixed to be set up in the workstation, accomplishes the positive rubber coating to upper cover plate 1, and the foaming glue in this step finally can solidify and form second adhesive tape 103, is located the outside of battery case, contacts with other parts in the car, plays the effect of buffering.
Before the front side gluing, in order to ensure the smoothness of the whole processing system, the upper cover plate 1 is firstly placed on a transfer table, in the traditional technology, the upper cover plate 1 is firstly moved from the transfer table to a gluing clamp 5 to carry out the front side gluing, after the front side gluing is finished, the upper cover plate 1 is turned over, and then the back side gluing can be carried out; however, the process increases the turnover procedure, and is more complex and lower in production efficiency.
The process that upper cover plate 1 moved, the glue gun was fixed is adopted to this embodiment, can shift to the in-process of rubber coating anchor clamps 5 at the revolving stage, accomplishes the front rubber coating, then places in rubber coating anchor clamps 5 according to 1 mode up in the back of upper cover plate, can directly get into the back rubber coating step, has saved the process of 1 turn-ups of upper cover plate, is showing and has improved production efficiency.
In one embodiment, in the step of back gluing, the upper cover plate 1 is fixed to a gluing jig 5, and the upper cover plate 1 is glued by a movable glue gun. The physical property requirement of upper cover plate 1 to the joint strip 101 at the back is high, consequently, in order to improve the rubber coating quality, prevent upper cover plate 1 with fixed rubber coating anchor clamps 5 on, prevent that upper cover plate 1 from producing the shake etc. to carry out accurate location through rubber coating anchor clamps 5, can improve upper cover plate 1's yields, promote upper cover plate 1's sealing performance.
In one embodiment, the baking temperature in the baking step is 80-100 degrees, most preferably 90 degrees, and the baking time is 8-10 min, so as to ensure the foaming adhesive to be cured completely and improve the physical properties.
In the further scheme, baking device 3 adopts double-deck baking oven, improves the quantity that toasts upper cover plate 1 simultaneously, improves machining efficiency.
