Detailed Implementation

[0012] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] Reference Figures 1 to 5 As shown, this utility model provides a battery top cover feeding device for a lithium battery explosion-proof sheet welding machine. In one embodiment, it includes a feeding and conveying mechanism 1, a first visual inspection mechanism 2 and a second visual inspection mechanism 3 arranged on one side of the feeding and conveying mechanism 1, and a laser marking mechanism 4 and a defective product transfer mechanism 5 arranged on the other side of the feeding and conveying mechanism 1. The laser marking mechanism 4 is located between the first visual inspection mechanism 2 and the second visual inspection mechanism 3, and a feeding lifting mechanism 6 is also arranged below the feeding and conveying mechanism 1 at a position corresponding to the laser marking mechanism 4. The defective product transfer mechanism 5 is located near the feeding and conveying mechanism 1. The feeding conveying mechanism 1 is arranged at one end, and a feeding tilting mechanism 7 is also arranged at one end. The feeding tilting mechanism 7 includes two feeding uprights 71, which are arranged opposite to each other. A tilting lifting cylinder 72 is installed on one side of each feeding upright 71. Each tilting lifting cylinder 72 drives and connects to a tilting vertical plate 73, and a tilting rod 74 is rotatably connected between the two tilting vertical plates 73. A tilting transfer plate 75 is connected to the tilting rod 74, and a tilting suction cup 76 is also installed on the tilting transfer plate 75. A tilting drive mechanism connected to the tilting rod 74 is also installed on one of the tilting vertical plates 73.

[0014] In this embodiment, the first vision inspection mechanism 2 includes two industrial cameras, respectively arranged above and below the loading and conveying mechanism 1, for detecting whether the battery top cover is placed backwards; the second vision inspection mechanism 3 includes an inspection camera arranged above the loading and conveying mechanism 1, for re-inspecting the battery top cover after the laser marking mechanism 4 marks it; during operation, an external robotic arm first transfers the battery top cover to the loading and conveying mechanism 1, which then transports it to the first vision inspection mechanism 2, where it checks whether the top cover is placed backwards. Subsequently, the loading and conveying mechanism 1 continues to transport it to the laser marking mechanism 4, where the loading lifting mechanism 6 lifts the battery top cover, and the laser marking mechanism 4 marks it (using an existing laser marking machine). After marking, the loading lifting mechanism 6 returns the battery top cover to the loading and conveying mechanism 1, which then transports the battery top cover to the second vision inspection mechanism 3. At mechanism 3, the second visual inspection mechanism 3 re-inspects the battery cover. After the re-inspection is completed, the feeding and conveying mechanism 1 conveys the battery cover to its end. If the re-inspection by the second visual inspection mechanism 3 fails, the defective product transfer mechanism 5 transfers the defective cover to the defective product hopper 8. If the battery cover is placed upside down, the flipping drive mechanism flips it (the flipping drive mechanism can drive the flipping rod 74 to rotate, and then the flipping suction cup 76 flips the battery cover 180°) and places it on the next conveying line. The qualified battery cover can be directly conveyed to the next conveying line. At the same time, a lifting mechanism is arranged below one end of the feeding and conveying mechanism 1. The lifting mechanism can lift the battery cover so that the defective product transfer mechanism 5 can transfer the defective product, and it also facilitates the feeding and flipping mechanism 7 to flip the cover. The structure of the lifting mechanism is similar to that of the feeding and lifting mechanism 6. Its working principle can be referred to the following discussion on the feeding and lifting mechanism 6, which will not be repeated here.

[0015] Preferably, in this embodiment, a first through hole is provided on each of the top two sides of the flipping transfer plate 75; the feeding and flipping mechanism 7 further includes a suction cup fixing block 77; the bottom of the suction cup fixing block 77 also extends downward with a first extension block, and the first extension block is inserted into the first through hole; the flipping suction cup 76 is installed on the suction cup fixing block 77, and the lower part of the flipping suction cup 76 passes through the first through hole. The position of the suction cup fixing block 77 can be adaptively adjusted according to the actual product size and type, which is highly versatile. At the same time, the flipping drive mechanism includes a flipping motor 731 installed on the flipping vertical plate 73, a first driving wheel 732 connected to the output shaft of the flipping motor 731, a first driven wheel 733 installed on the flipping rod 74, and a first synchronous belt 734 wound between the first driving wheel 732 and the first driven wheel 733.

The defective product translation mechanism can drive the defective product translation plate 51 to move along the length of the vertical feeding and conveying mechanism 1, moving the defective product translation plate 51 above the feeding and conveying mechanism 1; then the defective product lifting cylinder 52 drives the defective product lifting plate 53 to descend, so that the discharge transfer nozzle 54 contacts the defective battery top cover and adsorbs it; then, the defective battery top cover is transferred into the defective product hopper 8.

[0017] Preferably, the defective product hopper 8 includes a hopper fixing frame 81, a hopper sliding frame 82 slidably connected to the hopper fixing frame 81, a hopper panel 83 connected to one end of the hopper sliding frame 82, and a first handle connected to one side of the hopper panel 83; each of the top ends of the hopper sliding frame 82 is provided with a positioning guide rod 84; a positioning insertion hole is opened at the top end of the hopper sliding frame 82 away from the hopper panel 83, and a positioning lifting cylinder 85 is installed on the hopper fixing frame 81 at the position corresponding to the positioning insertion hole; the positioning lifting cylinder 85 is also driven by a positioning rod 86. The defective product hopper 8 adopts a drawer-type structure, which makes it easy to remove the battery top cover. At the same time, it is equipped with a positioning guide rod 84. The battery top cover has a positioning hole. When placing the battery top cover, the positioning guide rod 84 passes through the positioning hole, which makes it easy to stack the battery top covers. In addition, it is also equipped with a positioning lifting cylinder 85. After the hopper sliding frame 82 is pushed to the predetermined position, the positioning lifting cylinder 85 can drive the positioning insert rod 86 to be inserted into the positioning insert hole to limit and fix it.

The two first sliding plates 651 are respectively connected to one side of a synchronous belt, and the two second sliding plates 661 are respectively connected to one side of another synchronous belt.
