When the first driving motor 504 drives the first conveying belt 501 to convey the battery 6 to be covered to the vicinity of the positioning plate 502, the servo motor drives the linear slide block 804 to move to the position of the battery 6 to be covered along the slide rail 805, at this time, the front and back action cylinders 803 move to the position, the front and back action cylinders 803 drive the first clamping cylinders 802 to stretch, the first clamping cylinders 802 drive the clamping plates 801 to clamp the battery 6 to be covered from two sides, then the servo motor drives the linear slide block 804 to further drive the front and back action cylinders 803 and the first clamping cylinders 802 to move to the position under the safety valve positioning die 402, the first clamping cylinders 802 place the battery 6 to be covered on the positioning plate 502 positioned under the safety valve positioning die 402, at this time, the safety valve positioning through holes 405 are just aligned with the positions of the battery 6 to be covered, after the pressing cylinders 403 drive the pressing rods 404 to press the safety valves 7 positioned in the safety valve positioning through holes 405 downwards, the safety valves 7 can be smoothly pressed to the acid injection holes of the battery 6 to be covered, then the pressing cylinders 403 drive the pressing rods 404 to move up, the servo motor drives the linear slide block 803 to further drive the first clamping cylinders 802 to move to the second conveying belt 503 to move to the second conveying belt so that the first conveying belt is driven to move to the first conveying belt to move to the position well.
It can be seen that, in this embodiment, before the battery 6 to be covered is transported to the safety valve positioning mold 402, the battery feeding and positioning device 8 can quickly move the battery 6 to be covered below the safety valve positioning mold 402 in advance to perform positioning and cover pressing, so that the safety valve cover pressing device 4 can install the safety valve 7 of the previous battery 6 to be covered before the next battery 6 to be covered reaches below, and quickly move the installed battery to the next process; therefore, the installation of the safety valve 7 can be completed under the condition that the conveying mechanism does not stop conveying, and the production efficiency is effectively improved; in addition, in this embodiment, the linear slide 804 is driven by the servo motor, so that the front-back actuating cylinder 803 and the first clamping cylinder 802 are driven to move back and forth along the sliding rail 805, and the servo motor can control the moving position of the linear slide 804 on the sliding rail 805 relatively accurately according to a program, so that the first clamping cylinder 802 can place the battery 6 to be pressed at a corresponding position on the positioning plate 502, so as to ensure that each acid injection hole on the battery 6 to be pressed is aligned with each safety valve positioning through hole 405 on the safety valve positioning mold 402 above the battery 6 to be pressed, and improve positioning accuracy.
Otherwise, this embodiment is identical to embodiment 2, and a detailed description thereof will be omitted.
Embodiment 4:
this embodiment is a further improvement of embodiment 3, and the main improvement is that: in embodiment 3, when the distance between the to-be-covered batteries 6 on the first conveyor 501 is small, the battery feeding and positioning device 8 cannot smoothly remove the to-be-covered battery 6 arranged at the first position (forefront), at this time, the to-be-covered battery 6 arranged at the second position can be pressed by the second clamping cylinder 9 arranged at one side of the first conveyor 501, as shown in fig. 11, so that the to-be-covered battery 6 is temporarily stopped to separate from the to-be-covered battery 6 at the first position, and after the batteries at the first position and the second position are separated, the battery feeding and positioning device 8 can smoothly remove the to-be-covered battery 6 at the first position to be positioned on the positioning plate 502.
Otherwise, this embodiment is identical to embodiment 3, and a detailed description thereof will be omitted.
The foregoing embodiments are merely illustrative of the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the present invention and to implement the same, not to limit the scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
