[0023] As Figure 1-8 shown, the embodiments of the present invention include:

[0024] A multi-curved surface battery bracket tape bonding device, including a machine table 1, an operation station 2, a two-axis synchronous handling mechanism 3, a feeding air gripper 4, a turning-over mechanism 5, a discharging air gripper 6, a first tape sticking device 7, and a second tape sticking device 8.

[0025] Among them, a battery bracket positive mold base 2201, a bracket front positioning mold cavity 2202, a positioning air gripper 2203, and a C-shaped extension arm 2204 are arranged on the positive-curved surface tape sticking platform 22. A bracket front positioning mold cavity 2202 is formed on the surface of the battery bracket positive mold base 2201.

The swing table 2302 is movably mounted on the swing base 2301. A reverse die holder for battery bracket 2303 is arranged at the center of the swing table 2302.

The reference position photoelectric sensor 23105 is connected to the servo motor 23101.

[0028] Further, the two-axis synchronous handling mechanism 3 is composed of an x-axis linear module 301, a back plate 302, a z-axis lifting cylinder 303, and an L-shaped lifting arm 304. The x-axis linear module 301 horizontally spans above all the working stations 2. The x-axis linear module 301 is equidistantly mounted with three groups of z-axis lifting cylinders 303 through the back plate 302. The z-axis lifting cylinders 303 are externally hung with L-shaped lifting arms 304. Each L-shaped lifting arm 304 is respectively connected to the feeding gripper 4, the turning mechanism 5, and the discharging gripper 6.

[0029] Further, the turning mechanism 5 is composed of an auxiliary material-gripping air claw 501, a first support 502, a second support 503, a rotary cylinder 504, a battery support positioning seat 505, a bearing seat 506, and a driven turntable 507.

[0030] Further, the first adhesive pasting device 7 is composed of a feeding linear module 701, a z-axis pneumatic slide 702, a secondary adhesive pasting cylinder 703, and a first curved surface negative pressure suction head 704. The z-axis pneumatic slide 702 is mounted on the feeding linear module 701. The secondary adhesive pasting cylinder 703 is vertically arranged on the z-axis pneumatic slide 702. The first curved surface negative pressure suction head 704 is suspended under the secondary adhesive pasting cylinder 703.

[0031] Further, the second adhesive pasting device 8 is composed of a manipulator 801, an electric gripper 802, and a second curved surface negative pressure suction head 803. The electric gripper 802 is assembled on the manipulator 801. The second curved surface negative pressure suction head 803 is arranged on the electric gripper 802.

[0032] As Figure 1 shown, the feeding conveyor line 21 is an equidistant conveyor line with battery support limiting tooling integrated at fixed points. Each battery support limiting tooling contains a battery support workpiece to be processed. As Figure 5 shown, there are two non-upward-facing arc surfaces on both sides of the reverse side of the battery support. As Figure 3 shown, there is a forward-facing ultrasonic arc surface in the center of the front side of the battery support. The arc surfaces with two different postures on both the front and back sides are used for installing the battery. In order to construct a battery pack, a special double-sided adhesive film needs to be pasted on the surface of the arc surface. This device has the function of automatically realizing the adhesive pasting process for non-uniform curved surfaces.

[0033] When the battery support workpiece flows through the two-axis synchronous handling mechanism 3 from the feeding conveyor line 21, it is carried by the feeding air claw 4 to the positive curved surface pasting platform 22. The first adhesive pasting device 7 sucks the adhesive film piece by negative pressure and transports it to the position directly above the battery support and presses it down to complete the pasting; As Figure 4 、 5As shown, before the second gluing device 8 performs the gluing action, it is necessary to use the directional swing device 2310 to tilt the swing table 2302 to make the arc surface of the battery holder face upwards. After the alignment, the manipulator 801 can implement the positive downward pressure gluing. In order to meet the requirements of the alignment and gluing of more than two arc surfaces with different sounds, the manipulator 801 synchronously completes the material picking action and the translation action of switching the pasting position during the process of adjusting the posture of the swing table 2302. The combination of the two can improve the gluing efficiency. Since the positive arc surface and the different arc surface are distributed on both sides of the battery holder, a flipping mechanism 5 is also set on the two-axis synchronous transport mechanism 3 to realize the coaxial flipping of the holder. The flipping mechanism 5 has a simple structure. Through the cooperation of the coaxial bearing 23103 and the rotating cylinder 504, the precise flipping action is synchronously realized under the cooperation of the upper-level clamp. The first gluing device 7 and the second gluing device 8 take materials from an independent double-sided adhesive tape feeder 900, and the double-sided adhesive tape feeder 900 can realize the actions of separating the release paper tape and clamping the release paper tape at a fixed length.

[0034] In summary, the present invention provides a multi-curved surface battery bracket tape bonding equipment, which executes the curved surface gluing process by stepping through a synchronous conveying mechanism. It can not only perform efficient gluing operations on the positive curved surface, but also solve the gluing problem of the eccentric curved surface through yaw adjustment, and has excellent execution efficiency and gluing accuracy.
