Description

Technical Field

[0001] The present invention relates to the technical field of battery production equipment, and in particular to an automatic battery protection sheet placing device. Background Art

[0002] At present, most battery manufacturers will place a protection sheet in most areas of the center of a single battery during the battery assembly process. This protection sheet can prevent the damage of the battery separator during the acid pumping process and the damage of the battery caused by foreign objects falling into the battery during use. Most of the currently used protection sheets are soft plastics with holes, which are processed into the required shape and placed between the battery case and the middle cover, and the electrolyte can be injected or sucked out through the holes. The most commonly used method for placing the protection sheet is to cut the purchased roll-shaped protection sheet into the required size with simple tools and then manually place it into the battery case. This method has a large labor intensity and low efficiency. Patent No. CN211578894U discloses an automatic protection sheet placing device before battery capping. By setting a strip cutting mechanism and a slicing mechanism on the frame, the protection sheet is cut into strips and slices by the strip cutting mechanism and the slicing mechanism, and then the protection sheet is transported to the placing hole by the transporting mechanism, and the protection sheet is pushed into the hole by the ejecting assembly, so as to complete the cutting and placing of the protection sheet.

[0003] During the production process, because the protection sheet is light in weight, it is easy to be deformed and warped during the assembly process, etc., resulting in the loss of the protection function of the protection sheet during the use of the battery. The existing protection sheet assembly mechanism lacks a protection sheet shaping mechanism and requires subsequent manual adjustment, thus affecting the production efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic battery protection sheet placing device. By setting a protection sheet cutting mechanism to cut the protection sheet, the cut protection sheet falls onto the blanking plate, the blanking mechanism jacks up the battery to the lower side of the blanking plate, and the pressing and flattening mechanism presses the protection sheet into the battery for assembly and shaping, solving the problem that the protection sheet is easy to warp after being installed in the background art.

[0005] The present invention provides an automatic battery protection sheet placing device, including a conveying table, a frame is arranged above the conveying table, and a protection sheet cutting mechanism is arranged on the frame; the right end of the frame is connected with a blanking plate, a blanking mechanism is arranged on the conveying table under the blanking plate, a top plate is arranged above the blanking plate, and a pressing and flattening mechanism is arranged under the top plate.

[0006] Further improvement lies in that: the protection sheet cutting mechanism includes a material feeding roller, a cutting roller, a cutting cylinder, and a cutting knife; the material feeding roller is arranged at the left end of the frame, the cutting roller is arranged in the middle of the frame, blades are installed on the surface of the cutting roller, the cutting cylinder is arranged above the connection between the frame and the blanking plate, and the cutting knife is connected to the lower output end of the cutting cylinder.

[0007] A further improvement lies in that: a plurality of blanking grooves are equidistantly arranged on the surface of the blanking plate, and the blanking grooves are separated by partition plates.

[0008] A further improvement lies in that: convex blocks are arranged on the inner side of the blanking grooves, and the convex blocks are telescopic structures.

[0009] A further improvement lies in that: the ejecting mechanism includes an ejecting plate and an ejecting cylinder; the ejecting plate is arranged on the conveying table, the ejecting cylinder is arranged on the lower side of the conveying table, and the output end of the ejecting cylinder is connected to the ejecting plate.

[0010] A further improvement lies in that: positioning plates are movably arranged on both sides of the ejecting plate.

[0011] A further improvement lies in that: the pressing and leveling mechanism includes a pressing cylinder and a pressing frame; the pressing cylinder is installed on the lower side of the top plate, and the pressing frame is installed on the lower end output end of the pressing cylinder.

[0012] A further improvement lies in that: an installation plate is installed in the pressing frame through a spring rod, a leveling frame is slidably arranged on the lower side of the installation plate through a slide rail, a leveling roller is arranged in the leveling frame, a leveling cylinder is arranged on one side of the pressing frame, and the output end of the leveling cylinder passes through the pressing frame and is connected to one side of the leveling frame.

[0013] The beneficial effects of the present invention are as follows: 1. By arranging a blanking plate and an ejecting mechanism under the blanking plate, the storage battery is lifted by the ejecting mechanism and attached to the lower side of the blanking plate. A pressing and leveling mechanism is arranged on the upper side of the blanking plate. The protective sheet is pressed from the blanking plate into the storage battery by the pressing and leveling mechanism, and the pressed protective sheet is shaped, so that the protective sheet is more fittingly installed in the storage battery, reducing the subsequent shaping work of the protective sheet in the storage battery, reducing the warping of the protective sheet, greatly improving the convenience of installing the protective sheet, and improving the production efficiency.

[0014] 2. By arranging a blanking plate, blanking grooves are arranged on the blanking plate, and the blanking grooves are separated by partition plates. Through the partitioning effect of the partition plates, the cut protective sheets are respectively placed on the blanking grooves, and convex blocks are arranged in the blanking grooves. The convex blocks support the protective sheets from the lower side, so that the protective sheets are stably placed. Moreover, the convex blocks adopt a telescopic structure and contract when the pressing and leveling mechanism presses down the protective sheets, so that the protective sheets are quickly and stably pressed into the storage battery, improving the convenience of pressing the protective sheets.

[0015] 3. By arranging a pressing frame, the protective sheet is pressed into the storage battery by the action of the pressing cylinder, so that the four sides of the protective sheet are attached to the inside of the storage battery; in the middle, the leveling frame is driven to move by the leveling cylinder, so that the leveling roller rolls on the surface of the protective sheet, so that the protective sheet is flatly attached to the inside of the storage battery, reducing the generation of warping of the protective sheet and improving the flatness of installing the protective sheet.
