DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0021] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0022] The production line processing table 1 includes two hydraulic push rods 2 symmetrically installed on the production line processing table 1, and the output ends of the two hydraulic push rods 2 are fixedly connected to the unloading push plate 3, a conveying frame 4 is installed at the bottom of the front side of the production line processing table 1, and a conveying track 5 is installed inside the conveying frame 4. A first weight sensor 7 is fixedly installed on the side of the inner wall of the conveying frame 4 close to the production line processing table 1, and a guide plate 8 is installed on the top of the first weight sensor 7. A baffle plate 9 is arranged on the top of the guide plate 8, and a receiving box 16 is arranged on the front of the guide plate 8, and a receiving plate is placed inside the receiving box 16 17, a second weight sensor 18 is installed at the bottom end of the receiving plate 17, a controller is provided on the outer wall of the conveying frame 4, the first weight sensor 7 and the second weight sensor 18 are electrically connected to the controller, the second weight sensor 18 is electrically connected to the two electromagnets 15 through the controller, the setting of the unloading push plate 3 plays a role in pushing the corresponding battery to unload, the setting of the first weight sensor 7 plays a role in weighing the battery unloaded to the guide plate 8, and the setting of the second weight sensor 18 plays a role in weighing the battery unloaded to the receiving plate 17.

[0023] In this embodiment, mounting frames 10 are fixedly installed on both sides of the top of the conveying frame 4, and top plates are fixedly installed on the tops of the two mounting frames 10. A hydraulic cylinder 11 is fixedly installed in the middle of the top of the top plate. The output end of the hydraulic cylinder 11 passes through the top plate and is fixedly connected to the middle of the top of the baffle 9. The baffle 9 is set to block and limit the battery, and the hydraulic cylinder 11 is set to drive the baffle 9 to rise and fall, so that the battery unloaded onto the guide plate 8 can be controlled for re-unloading.

[0024] In this embodiment, a sleeve 12 is fixedly passed through the front side of the top of the top plate, and a movable rod 13 is slidably connected to the bottom of the inner wall of the sleeve 12. A rack 19 is fixedly installed on the side adjacent to the output end of the movable rod 13 and the hydraulic cylinder 11, and a gear 20 is provided on the side adjacent to the two racks 19. The outer walls of the gear 20 are meshed with the outer walls of the two racks 19. When the gear 20 is meshed with the two racks 19, when the gear 20 rotates, it can drive the movable rod 13 and the output end of the hydraulic cylinder 11 to rotate in the opposite direction, thereby realizing the effect of the baffle 9 rising to the receiving box 16 descending, so that the batteries on the guide plate 8 can be just diverted to the inside of the receiving box 16, and connecting rods 21 are fixedly connected to both ends of the gear 20, and one end of the two connecting rods 21 is rotatably connected to the adjacent mounting frames 10. The setting of the connecting rod 21 serves to assist the installation and rotation of the gear 20.

[0025] In this embodiment, the bottom end of the movable rod 13 is fixedly connected to a connecting frame 14, and electromagnets 15 are embedded on both sides of the bottom end of the connecting frame 14. The two electromagnets 15 are magnetically connected to the top of the receiving box 16, and the bottom end of the receiving box 16 is placed on the conveying track 5. The setting of the electromagnet 15 plays a role in magnetically adsorbing the receiving box 16, thereby playing a role in limiting the receiving box 16.

[0026] In this embodiment, a collection box 6 is placed on the other side of the front of the production line processing table 1, and the bottom ends of the two unloading push plates 3 are slidably connected to the top of the production line processing table 1. The setting of the collection box 6 serves to receive unqualified batteries.

[0027] Working principle: When in use, qualified batteries are pushed onto the guide plate 8 by the operation of one of the hydraulic push rods 2 to drive the unloading push plate 3. After the first weight sensor 7 recognizes that the number has reached the set threshold, it drives the hydraulic cylinder 11 to operate the baffle 9 to rise and expand the space between the baffle 9 and the guide plate 8. At this time, the output end of the hydraulic cylinder 11 rises, driving one of the racks 19 to rise vertically, and driving the other rack 19 to descend vertically under the meshing rotation of the gear 20, thereby driving the movable rod 13 to slide vertically and descend in the sleeve 12, and further driving the receiving box 16 to descend under the connection of the connecting frame 14. At this time, the distance between the baffle 9 and the guide plate 8 is enlarged, so that the battery slides through the guide plate 8 and just falls into the receiving box 16. When the receiving box 16 receives batteries of the same weight, the second weight sensor 18 receives the weight signal and transmits the signal to the two electromagnets 15, triggering the electromagnet 15 to cut off the power, so that after the connecting frame 14 is separated from the receiving box 16, the conveying track 5 runs to convey a sufficient amount of batteries, thereby achieving the effect of quantitative unloading.
