DETAILED DESCRIPTION

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0019] Figure 1 It is a structural schematic diagram of the present invention, Figure 2is a structural schematic diagram of the film edge bending mechanism of the present invention, Figure 3 It is a structural schematic diagram of the battery turning mechanism of the present invention.

[0020] As attached Figure 1 As shown, an efficient battery film pasting device includes a machine platform 1, a film roll feeder 2, a film transporting mechanism 3, a conveyor 4, a film edge bending mechanism 5, a battery flipping mechanism 6, a finished battery discharging mechanism 7 and an empty jig discharging mechanism 8. The conveyor 4, two film roll feeders 2, two film transporting mechanisms 3, a film edge bending mechanism 5, a battery flipping mechanism 6, a finished battery discharging mechanism 7, and an empty jig discharging mechanism 8 are all installed on the machine platform 1, and the conveyor 4 is located below the film edge bending mechanism 5.

[0021] The film handling mechanism 3 is composed of a multi-axis robot and a suction plate. The multi-axis robot is equipped with a suction plate, and a plurality of suction holes are distributed on the plane of the suction plate. The suction holes are connected to a vacuum generator to generate negative pressure suction.

[0022] The film roll feeder 2 is composed of an active roller, a passive roller, a motor, a roll shaft, a frame and a CCD camera. The active roller, the passive roller and the roll shaft are all rotatably connected to the frame, the motor and the CCD camera are fixed on the frame, and the output shaft of the motor is fixed to one end of the active roller. The roll shaft is loaded with a Mylar film roll, and the Mylar film passes between the active roller and the passive roller and is clamped by the active roller and the passive roller. The motor drives the active roller to rotate, and the active roller drives the passive roller to rotate by friction. The continuous rotation of the active roller and the passive roller can pull the Mylar film forward. The CCD camera can transmit the specific position of the Mylar film sheet to be taken on the Mylar film roll to the control machine. The control machine controls the multi-axis robot of the film handling mechanism 3 to move to the accurate position according to the specific position information of the Mylar film sheet, and removes the Mylar film sheet from the flat part of the Mylar film roll.

[0023] The conveyor 4 is a double-belt belt conveyor, and a plurality of blocking cylinders are fixed on the conveyor 4 .

[0024] As attached Figure 2 As shown, the film edge bending mechanism 5 is composed of a flat plate 51, an L-shaped push plate 52, a horizontal pushing cylinder 53 and a lifting cylinder 54. The flat plate 51 is located above the conveyor 4. Several horizontal pushing cylinders 53 are fixed on the upper plane of the flat plate 51. The L-shaped push plate 52 is fixed on the piston rod of the horizontal pushing cylinder 53. A hole groove matching the shape of the battery is provided on the lower plane of the flat plate 51. The lifting cylinder 54 is located directly below the flat plate 51.

[0025] The film edge bending mechanism 5 works as follows: when the jig is moved to the top of the lifting cylinder 54, the lifting cylinder 54 pushes the jig upward, and the jig is separated from the belt of the conveyor 4 and moves upward. When the battery on the jig moves up to the hole slot inserted into the bottom of the flat plate 51, the portion of the Mylar film attached to the battery that exceeds the battery will be bent by the hole slot of the flat plate 51, and the bent portion of the Mylar film will be attached to the side of the battery. At this time, the bent portion of the Mylar film is longer than the side of the battery. Finally, the piston rods of several horizontal push cylinders 53 drive the L-shaped push plate 52 to move horizontally, and the L-shaped push plate 52 will bend the portion of the Mylar film that has been bent that exceeds the side of the battery again, so that the Mylar film that exceeds the side of the battery can be attached to the bottom surface of the battery, thereby completing the edge wrapping of the battery.

[0026] As attached Figure 3 As shown, the battery flipping mechanism 6 is composed of a lifting plate 61, a vertical bracket 62, a slider 63, a waist-shaped plate 64, a vertical plate 65 and a lifting plate driving cylinder 66. The vertical bracket 62 is fixed on the machine platform 1, the slider 63 is slidably connected to the vertical bracket 62, the waist-shaped plate 64 is rotatably connected to the slider 63, a torsion spring is connected between the waist-shaped plate 64 and the slider 63, the waist-shaped plate 64 is fixed to the lifting plate 61 through a rotating rod, a number of suction cups are distributed on the lifting plate 61, the vertical plate 65 is fixed on the vertical bracket 62, a notch is provided on one side of the vertical plate 65 for rotating the waist-shaped plate 64, and the slider 63 is fixed on the piston rod of the lifting plate driving cylinder 66.

[0027] The working mode of the battery flipping mechanism 6 is that the lifting plate driving cylinder 66 can drive the slider 63 to slide up and down along the vertical bracket 62, and the slider 63 will drive the waist plate 64 and the lifting plate 61 to move up and down synchronously. The waist plate 64 is located on one side of the vertical plate 65. When the slider 63 is located at the bottom, the vertical plate 65 restricts the waist plate 64, and the torsion spring on the waist plate 64 is in a tensioned state. When the waist plate 64 moves up to the notch of the vertical plate 65, the waist plate 64 rotates to a horizontal state driven by the rebound of the torsion spring. Then the waist plate 64 continues to move upward. When the waist plate 64 is out of contact with the notch of the vertical plate 65, the waist plate 64 has rotated 180 degrees. In this way, the waist plate 64 can drive the lifting plate 61 to rotate 180 degrees during the rising process. The suction cup on the lifting plate 61 is connected to the vacuum generator and generates negative pressure suction. After the battery moves to the bottom of the lifting plate 61, the lifting plate 61 moves down and sucks the battery. Then the lifting plate 61 rises with the battery, and when it reaches the top, it flips 180 degrees, so that the bottom of the battery faces upward, and finally the film can be attached to the bottom of the battery.

[0028] The finished battery discharging mechanism 7 and the empty fixture discharging mechanism 8 are both composed of a rodless cylinder, a lifting cylinder and a suction nozzle. The cylinder body of the rodless cylinder is fixed on the machine platform 1, the lifting cylinder is fixed on the slide seat of the rodless cylinder, and several suction nozzles are fixed on the piston rod of the lifting cylinder. The rodless cylinder can drive the lifting cylinder to move horizontally and linearly, and the lifting cylinder can drive the suction nozzle to move vertically and linearly. The suction nozzle is connected to the vacuum generator and generates negative pressure suction.

[0029] The working mode of the film laminating equipment is that the battery to be film-laminated is first placed on the jig, and then the jigs loaded with batteries are placed one by one on the conveyor 4. When the first jig moves to the processing station, the piston rod of the blocking cylinder behind the first jig extends to block other jigs following behind.

[0030] After the first jig moves to the front film laminating station, the piston rod of the blocking cylinder in front of the jig extends out and blocks the jig, and then the film conveying mechanism 3 of the front film laminating grabs a piece of Mylar film from the first roll film feeder 2 and laminates it to the front of the battery. Then the jig carrying the battery moves horizontally to the bottom of the flat plate 51 of the film edge bending mechanism 5, where the blocking cylinder also blocks the jig's way. Then the film edge bending mechanism 5 wraps the battery side with the Mylar film.

[0031] After the hemming is completed, the lifting cylinder 54 lowers the jig to the belt of the conveyor 4 again, and then moves the jig horizontally toward the battery flipping mechanism 6. The battery flipping mechanism 6 flips the battery upward. At this time, the film conveying mechanism 3 for the back film grabs a piece of Mylar film from the second film roll feeder 2 and attaches it to the back of the battery. After the back film is attached, the battery flipping mechanism 6 puts the battery back into the jig.

[0032] Then the jig moves to the finished battery discharging mechanism 7, which takes away the battery with the film on the jig. Finally, the emptied jig continues to move forward to the empty jig discharging mechanism 8, which takes the empty jig from the conveyor 4.

[0033] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
