[0035] The following combines the attached drawings and preferred embodiments to detail the specific implementation manners of the present utility model.

[0036] As shown in Figure 1 - Figure 2 the figure, an automatic pad printing device for polymer soft-pack batteries includes a frame 1, and a four-axis robot loading mechanism 2, a four-axis robot unloading mechanism 3, a pad printing mechanism 4, a battery transfer mechanism 5, and a CCD photographing mechanism 6 installed on the frame; cabinet doors 11 are installed around the frame.

[0037] The pad printing mechanism is located in the middle of the frame and is used for pad printing the batteries.

[0038] The battery transfer mechanism is located on one side of the pad printing mechanism and is used for transferring the batteries to one side of the pad printing mechanism.

[0039] The four-axis robot loading mechanism and the four-axis robot unloading mechanism are respectively arranged on both sides of the pad printing mechanism. The four-axis robot loading mechanism is used for placing the batteries on the battery transfer mechanism, and the four-axis robot unloading mechanism is used for taking the pad-printed batteries from the battery transfer mechanism and placing them in an empty tray.

[0040] The CCD photographing mechanism is used for photographing the batteries. After the photographing data is completed, the pad printing mechanism performs pad printing according to the coordinates fed back by the PLC.

[0041] As shown in Figure 3 the figure, the four-axis robot loading mechanism 2 includes a four-axis robot 21, a tray transfer mechanism 22, a tray lifting mechanism 23, and a tray limiting mechanism 24. The four-axis robot can accurately place the batteries on the transfer mechanism, with a repeatability accuracy of (±0.02 mm). The tray transfer mechanism is located on one side of the four-axis robot and can carry the empty trays. The tray lifting mechanism can lift the trays, and the tray limiting mechanism limits the trays.

[0042] Specifically, as shown in Figure 4 the figure, the four-axis robot includes a robot base 211, a four-axis manipulator 212, a suction cup holder 213, and suction cups 214. The four-axis manipulator is fixed to the frame through the robot base. The suction cup holder is installed at the moving end of the four-axis manipulator, and the suction cups are fixed to the suction cup holder. The four-axis manipulator drives the suction cup holder and the suction cups to move, and the suction cups can adsorb the trays.

[0043] As shown in Figure 5As shown, there are two tray limiting mechanisms 24, which are arranged in parallel. The tray limiting mechanism includes a left limiting plate 241, a right limiting plate 242, and a back plate 243. The left limiting plate and the right limiting plate are connected to one side of the back plate through an adjustment slide rail 244. The tray lifting mechanism is arranged in the middle of one side of the back plate, and the tray transfer mechanism is fixed between the two tray limiting mechanisms. The distance between the left limiting plate and the right limiting plate is adjusted according to the width of the tray to ensure that the tray can enter smoothly.

[0044] The four-axis robot blanking mechanism has the same structure as the four-axis robot loading mechanism.

[0045] As Figure 5 shown, the tray transfer mechanism 22 includes a tray transfer module 221, a tray lifting cylinder 222, a lifting plate 223, and a lifting suction cup 224. The tray transfer module is horizontally arranged between the two back plates. The tray lifting cylinder is installed at the movable end 225 of the tray transfer module. The lifting plate is fixed on the piston rod of the tray lifting cylinder, and the lifting suction cup is fixed at the end of the lifting plate. As Figure 5 shown, assuming Figure 5 is the loading station. At this time, the worker first places the tray filled with batteries on the tray lifting mechanism inside the left limiting mechanism. After the four-axis robot takes away the batteries in the topmost tray, the lifting suction cup adsorbs the topmost empty tray under the drive of the tray lifting cylinder. Then, the tray transfer module moves the empty tray to the right limiting mechanism, and the tray lifting mechanism in the right limiting mechanism descends by the distance of one tray, and so on. If Figure 5 is the blanking station, then first place empty trays in the left limiting mechanism. First, the tray transfer mechanism takes out an empty tray and places it in the right limiting mechanism. After the four-axis manipulator fills the empty tray with batteries, the tray lifting mechanism descends by the distance of one tray, and then takes another empty tray and places it on the top of the right limiting mechanism, and stacks them up in turn.

[0046] As Figure 6 shown, the tray lifting mechanism 23 includes a lifting module 231 and a tray 232. The lifting module is vertically fixed inside the back plate, and the tray is fixed at the movable end of the lifting module. The lifting module drives the tray to rise or fall by the distance of one tray.

[0047] As Figure 7 shown, the pad printing mechanism 4 includes a pad printing platform 41 and a three-axis module mechanism 42. The pad printing platform can adjust its position, and the three-axis module mechanism drives the printing head to move to print on the surface of the battery.

[0048] As Figure 8As shown, the pad printing platform includes a pad printing base 411, a pad printing motor 412, and a movable printing table 413. The movable printing table is slidably engaged with the pad printing base, and the pad printing motor drives the movable printing table to move. The pad printing motor adjusts the position of the movable printing table through a lead screw pair.

[0049] As Figure 9 shown, the three-axis module mechanism 42 includes an X-axis movement module 421, a Y-axis movement module 422, and a Z-axis movement module 423. The X-axis movement module is installed on a moving frame 424. One end of the moving frame is slidably connected to the upper part of the left support frame 425 through a slide rail. The other end of the moving frame is connected to the movable end of the Y-axis movement module. The Z-axis movement module is movably connected to the X-axis movement module, and a rubber head 426 is installed at the movable end of the Z-axis movement module. The Z-axis movement module adjusts the position of the rubber head up and down. In a plane, the rubber head first picks up ink on the printing table and then moves to the battery transfer mechanism to print on the surface of the battery.

[0050] As Figure 10 shown, the battery transfer mechanism 5 includes a conveyor belt 51 and a conveyor belt support 52. The conveyor belt is installed on the machine frame through the conveyor belt support. The conveyor belt drives the battery to move.

[0051] As Figure 11 shown, the CCD photographing mechanism 6 includes a camera support 61 and a CCD camera 62. The CCD camera is fixed on the camera support, and the camera support is located on one side of the battery transfer mechanism. In order to ensure that the pad printing position meets the process requirements, the battery is photographed by the CCD alignment mechanism. After the photographing data is completed, the three-axis robotic arm performs pad printing according to the coordinates fed back by the PLC.

[0052] As Figure 12 shown, a sticker recycling mechanism 7 is provided on one side of the pad printing mechanism. The sticker recycling mechanism includes a peeling plate 71, a recycling roller 72, pinch rollers 73, a recycling motor 74, and a recycling support 75. The recycling motor is installed on the recycling support. The pinch rollers are installed at the output end of the recycling motor. The peeling plate is fixed on the recycling support. The recycling roller is installed below the peeling plate. A pressure roller 76 is provided on the upper part of the peeling plate. The rubber head 426 first stamps the pattern on the printing table 413, and then the rubber head 426 transfers the stamped pattern to the battery body. After the pad printing is completed, the rubber head 426 goes to the sticker to clear the stamped information, then returns to the printing table 413, and finally the sticker is recycled by the sticker recycling mechanism.

[0053] It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
