Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-6The present invention provides a technical solution: an automatic feeding and screw pressing device for an SMC composite material new energy upper cover, comprising a feeding component 1 and a pressing component 2, the feeding component 1 comprising a first base 3, and a feeder is respectively arranged on the two side areas on the top of the first base 3, namely a first feeder 4 and a second feeder 5, the first feeder 4 and the second feeder 5 are existing technical structures and are not described in detail here. The first feeder 4 is used to convey screws, and the second feeder 5 is used to convey nuts. A first conveying trough 6 is arranged at the output end of the first feeder 4, and a second conveying trough 7 is arranged at the output end of the second feeder 5. The first conveying trough 6 is higher than the second conveying trough 7, and the two positions are in a same row and superimposed structure, so that The screw is inserted into the nut to form a complete material, a first metal frame 8 is arranged above the feeding and conveying ends of the first conveying trough 6 and the second conveying trough 7, a first hydraulic press 9 is arranged on the first metal frame 8, the output end of the first hydraulic press 9 is downward and a first motor 10 is fixedly installed, the output end of the first motor 10 is downward and a first support rod 11 is fixedly installed, a pressure rod 12 is fixedly installed at the bottom end of the first support rod 11, and the bottom end of the pressure rod 12 is a circular edge with an inward chamfer. This structural setting facilitates the bottom end of the pressure rod 12 to contact the top of the screw and better limit the position of the screw. The top of the screw used in this embodiment is set to a hollow groove structure, and the hollow groove structure of the screw matches the circular edge of the inward chamfer at the bottom end of the pressure rod 12; The feeding and conveying ends of the first conveying trough 6 and the second conveying trough 7 are fixedly mounted on the first metal frame 8. Since the first conveying trough 6 is located at a relatively high position, a heightening plate 14 is provided at its bottom to limit the position; A U-shaped slot block 13 is arranged at the feeding and conveying end of the first conveying slot 6 and the second conveying slot 7, the groove opening of the U-shaped slot block 13 faces the first feeder 4, and the bottom of the U-shaped slot block 13 faces the extended metal plate fixed on the first metal frame 8, thereby completing the position limitation of the U-shaped slot block 13; A positioning card door assembly 15 is arranged in front of the feeding and conveying end of the first conveying trough 6 and the second conveying trough 7. The positioning card door assembly 15 includes a first driving member 16 fixedly mounted on the first metal frame 8. The first driving member 16 is connected to a lifting plate 17 arranged in front of the feeding and conveying end of the first conveying trough 6 and the second conveying trough 7. After a screw is inserted into a nut and the initial clamping action is completed, the lifting plate 17 is lowered by driving the first driving member 16, so that the material can be conveyed to the pressing assembly 2 through the long slot 18 arranged on the first metal frame 8; A second driving member 19 is arranged at the rear side of the U-shaped groove block 13 and in the same row as the lifting plate 17. The output end of the second driving member 19 faces the long groove 18 and is fixedly installed with a push rod 20. There is no blocking structure in the front movement area of ​​the push rod 20. The screw is placed in the first feeder 4, and the nut is placed in the second feeder 5. The first feeder 4 and the second feeder 5 are operated to insert the screw into the nut. After the screw is inserted into the nut, the first hydraulic press 9 is driven to operate and drive the first motor 10 to descend. The first motor 10 descends and drives the first support rod 11 to descend. The first support rod 11 descends and drives the pressure rod 12 to descend until the bottom end of the pressure rod 12 contacts the top of the screw. The first hydraulic press 9 is connected to the automation system, and the bottom end of the pressure rod 12 contacts the top of the screw. This is completed by the data preset in the automation system. After the operation of the first hydraulic press 9 is completed, the first hydraulic press 9 is driven to operate and drive the first motor 10 to descend. The first motor 10 descends and drives the first support rod 11 to descend. The first support rod 11 descends and drives the pressure rod 12 to descend until the bottom end of the pressure rod 12 contacts the top of the screw. The operation of a motor 10 drives the first support rod 11 to rotate, and the rotation of the first support rod 11 drives the pressure rod 12 to rotate. Since the structure of the pressure rod 12 matches the screw, the screw is screwed into the nut, so that the screw and the nut form a complete material. During the rotation of the first motor 10, the first hydraulic press 9 drives the first motor 10 to descend a small distance again. This small distance is a preset value set in the automation system, so that the screw can achieve the effect of being engaged with the nut. Through the coordinated work of the first feeder 4 and the second feeder 5, automatic feeding and assembly of screws and nuts are realized, which greatly improves production efficiency. A pressure sensor 21 is arranged at the feeding and conveying end of the first conveying trough 6 and the second conveying trough 7 and also below the U-shaped trough block 13. The function of the pressure sensor 21 is to detect. The first detection process is to detect whether nuts and screws are conveyed here. The mass of a single nut and a screw is a fixed value, which is pre-set in the automation system. If the pressure sensor 21 detects that the value is not within the preset range, a manual inspection is called. The second detection process is to detect whether the first motor 10 exerts pressure on the screw and the nut during the process of the first motor 10 screwing the screw into the nut. If there is no pressure value feedback, a manual inspection is called. The advanced positioning device and sensor technology are used to ensure that the screw can be accurately aligned with the nut, thereby improving the accuracy and consistency of fixation. The pressing assembly 2 includes a second base 22 arranged on one side of the first base 3, and first transverse rails 23 are symmetrically arranged on both sides of the second base 22. The first transverse rail 23 is slidably connected to a second metal frame 24, and the second metal frame 24 is connected to a third driving member 28 arranged in the second base 22.

The second motor 37 is driven to run and drive the second support rod 38 to rotate, and the rotation of the second support rod 38 drives the fill light source assembly 34 to rotate and then change its position, so as to achieve the purpose of actively performing fill light according to the operation time of the camera assembly 36. When the camera assembly 36 is not in operation, the fill light source assembly 34 is driven to rotate to a position that is not under the pressing rod 33 to avoid blocking the operation path of the pressing rod 33. A side plate 39 is fixedly installed on the side wall of the support plate 25 extending downward, and a calibration assembly 40 is fixedly installed on the side wall of the side plate 39. The calibration assembly 40 includes a calibration plate 41 fixedly installed on the side wall of the side plate 39. The calibration plate 41 is provided with upwardly curved baffles around it. The middle area of ​​the calibration plate 41 is a hollow space 42. First telescopic rods 43 are symmetrically installed on the concave areas in the middle of the two lateral side walls of the hollow space 42. Top plates 44 are fixedly installed on the ends of the first telescopic rods 43. Before the material is transported to the calibration plate 41, the first telescopic rod 43 is driven to extend, driving the two top plates 44 to move toward each other, thereby reducing the hollow area of ​​the middle concave area of ​​the hollow space 42 to prevent the material from escaping from the middle concave area of ​​the hollow space 42. A second telescopic rod 45 is symmetrically mounted on the transverse baffle of the alignment plate 41, and a first push plate 46 is fixedly mounted on the end of the second telescopic rod 45; a third telescopic rod 47 is symmetrically mounted on the longitudinal baffle of the alignment plate 41, and a second push plate 48 is fixedly mounted on the end of the third telescopic rod 47; Before the material enters the alignment plate 41, the hollow area of ​​the hollow space 42 is first reduced, and then the second telescopic rod 45 is driven to extend, and the extension of the second telescopic rod 45 drives the first push plate 46 to move, and then the materials transported to the alignment plate 41 are arranged neatly horizontally, and then the third telescopic rod 47 is driven to extend, and the extension of the third telescopic rod 47 drives the second push plate 48 to move, and then the materials that have been neatly arranged horizontally are pushed together. At this point, the positions of all materials on the alignment plate 41 are corrected correctly, and the camera assembly 36 is turned on to monitor the position of the materials below, and the fill light source assembly 34 is turned on at the same time to improve the monitoring accuracy. The purpose of the detection is to ensure that the screw position of each material is correctly inserted into the nut; After the camera assembly 36 has finished detecting, the second push plates 48 on both sides are driven to move in coordination, and the middle one of the materials arranged in a row is moved to the middle area of ​​the hollow space 42, and then the pressing rod 33 is driven to descend to drive the magnetic suction assembly 49 arranged at the bottom thereof to adsorb the top of the material, and then the top plate 44 is driven to shrink so that the middle hollow area of ​​the hollow space 42 is increased, so that the material is pressed into the upper cover. In the process of pressing the material, the second metal frame 24, the support block 29, and the second hydraulic press 32 are driven to move in coordination to move the pressing rod 33 to the vertical upper side of the area where the material needs to be pressed on the upper cover, and then the second hydraulic press 32 and the pressing rod 33 are driven to operate autonomously to press the material in, and the pressing of the material is completed. This process of pressing the material can adapt to materials of different specifications and types, as well as battery pack upper covers of different shapes and sizes, to meet diversified production needs; Two sets of top rails 35 are arranged on the top of the second base 22, and each set of top rails 35 is slidably connected to the bearing plate 26, and the upper cover and the structure to be connected to the upper cover are placed on the bearing plate 26. The pressing assembly 2 can press screws on the two upper covers at the same time, thereby reducing the operating interval time of the pressing assembly 2 and improving the pressing efficiency; The long slot 18 matches the position of the alignment plate 41, and the materials conveyed through the long slot 18 directly enter the alignment plate 41, and multiple materials can be conveyed into the alignment plate 41 at one time; If the camera assembly 36 detects that the material is unqualified, such as missing screws or nuts, the material is moved above the top plate 44 and the top plate 44 is retracted so that the material falls off the calibration plate 41 without manual inspection and sorting.
