[0089] Due to the presence of the alarm cylinder 10, the piston rod controlling the alarm cylinder 10 remains stationary, which can keep the upper track groove mounting seat 401 stationary, ensuring that roller 1 904 and roller 2 can move normally in track groove 1 4011 and track groove 2 4012; when roller 1 904 and / or roller 2 are stuck in track groove 1 4011 and / or track groove 2 4012 and cannot move further, the upper turntable 402 rotates, and the outer rod 903 and inner rod can push the upper track groove mounting seat 401 to rotate accordingly, thereby driving the alarm cylinder 10 to extend or shorten. When the alarm cylinder 10 extends or shortens, it indicates that roller 1 904 and / or roller 2 are stuck in track groove 1 4011 and track groove 2 4012, which serves as a fault alarm.

[0090] The connection point between the alarm cylinder 10 and the upper track groove mounting seat 401 needs to be far away from the center of the upper track groove mounting seat 401 to ensure that the alarm cylinder 10 can be extended and retracted when the upper track groove mounting seat 401 rotates.

[0091] Furthermore, a sealing mold 901 is provided at the lower end of the outer rod 903, and a sealing hole 9011 is provided at the bottom of the sealing mold 901, and the sealing hole 9011 is a blind hole with an opening at the bottom; a sealing chamfer 9012 is provided at the bottom opening of the sealing hole 9011; the sealing chamfer 9012 is used to press the top edge of the battery casing so that the top edge of the battery casing is bent inward; the lower end of the inner rod passes through the sealing hole 9011 and can move up and down in the sealing hole 9011.

[0092] Since the sealing chamfer 9012 is an inclined surface, when the sealing mold 901 is pressed down, the inclined surface contacts the top edge of the battery shell, which can guide the top edge of the battery shell to bend inward, thereby wrapping the rubber ring.

[0093] Furthermore, the pressing rod 908 includes a rod body 9081 and a rod head 9082; the upper end of the rod body 9081 is inserted into the pressing rod mounting hole 902 and connected to the lower end of the buffer spring 907, and the lower end of the rod body 9081 is connected to the upper end of the rod head 9082; the diameter of the lower end of the rod head 9082 is smaller than the inner diameter of the rubber ring, and the diameter of the upper end of the rod head 9082 is larger than the inner diameter of the rubber ring; Figure 5 As shown, the rod head 9082 is a conical shape with a larger top and smaller bottom. When the push rod 908 moves downward, the lower end of the rod head 9082 inserts into the rubber ring, causing the rubber ring to fit over the rod head 9082 and onto the inclined surface of the conical shape. Because the upper end of the rod head 9082 is larger, the upper end of the rod head 9082 can push the rubber ring into the battery housing. Optimally, the rubber ring fits over the lower end of the rod head 9082, with the bottom surface of the rubber ring flush with the bottom surface of the rod head 9082.

[0094] The axis of the inner rod coincides with the axis of the sealing hole 9011, so as to ensure that the rubber ring and the battery shell are concentric, and that each edge of the top of the battery shell bends inward to the same size when pressed.

[0095] In specific implementation, the diameter of the sealing hole 9011 is smaller than the diameter of the battery shell, so as to ensure that the sealing chamfer 9012 can be pressed on the top edge of the battery shell without causing the top edge of the battery shell to enter the sealing hole 9011; the sealing hole 9011 is larger than the outer diameter of the rubber ring, so as to prevent the front end of the sealing mold 901 from touching the rubber ring and crushing the rubber ring.

[0096] Furthermore, a positive electrode accommodating hole 9013 is provided at the bottom of the rod head 9082, and the positive electrode accommodating hole 9013 is a blind hole with an opening at the bottom; the depth of the positive electrode accommodating hole 9013 is greater than the height of the positive electrode, and the diameter of the positive electrode accommodating hole 9013 is greater than the diameter of the positive electrode.

[0097] Due to the existence of the positive head accommodating hole 9013, the positive head of the battery enters the positive head accommodating hole 9013, which can prevent the positive head on the positive cap from contacting the inner rod, prevent the positive head from being crushed, and prevent the positive head from being conductive after contacting the inner rod; at the same time, when the rubber ring is sleeved on the lower end of the rod head 9082, the bottom surface of the rubber ring is flush with the bottom surface of the rod head 9082, and the positive head enters the positive head accommodating hole 9013, the rubber ring can just be located on the surface of the positive cap, so that it is convenient for the top edge of the battery shell to wrap it.

[0098] Furthermore, a return spring 905 is provided in the outer rod 903, the upper end of the return spring 905 is connected to the top of the outer rod 903, and the lower end of the return spring 905 is connected to the upper end of the driving rod 906. The return spring 905 is used to drive the inner rod to move upward and reset.

[0099] Furthermore, an insulating head is provided on the top of the lifting rod 8 to avoid conduction when the lifting rod 8 contacts the bottom of the battery.

[0100] Further, such as Figure 6 As shown, in the toss 7, the axes of the battery mounting hole 701 and the lifting hole 702 coincide with each other, and the diameter of the battery mounting hole 701 is larger than the diameter of the lifting hole 702.

[0101] In this embodiment, the battery loading device 1, the rubber ring loading device 2 and the unloading device 3 have the same structure, and all include a material tray, an arc-shaped baffle and a bottom plate;

[0102] Among them, such as Figure 7As shown, the battery loading device 1 includes a material tray 101, a curved baffle 102 and a bottom plate 1; the material tray 101 is horizontally arranged and can rotate in the horizontal direction; a number of battery fixing grooves 103 arranged at equal intervals are provided on the side wall of the material tray 101; the battery fixing grooves 103 are vertically arranged and cover the entire circle of the material tray 101; the curved baffle 102 is located on the outside of the material tray 101, and there is a gap between the curved baffle 102 and the material tray 101, and the gap forms a battery feeding channel between the curved baffle 102 and the material tray 101; the bottom plate 1 is located below the battery feeding channel; the outlet of the battery feeding channel is located between the sealing rod 9 and the support 7.

[0103] During operation, batteries enter the battery feed channel from the entrance and are positioned in battery holding slots 103. The feed tray 101 then rotates, moving the batteries through the battery feed channel and delivering them to the outlet. Because the battery holding slots 103 are evenly spaced, they can separate the batteries by a certain amount, ensuring sufficient operating time between adjacent batteries, facilitating the operation of each battery at the subsequent station.

[0104] Among them, the rubber ring loading device 2 includes a second material tray, a second arc-shaped baffle and a second bottom plate; the second material tray is horizontally arranged and can rotate in the horizontal direction; a number of rubber ring fixing grooves arranged at equal intervals are provided on the side wall of the second material tray; the rubber ring fixing grooves are vertically arranged and cover the entire circle of the second material tray; the second arc-shaped baffle is located on the outside of the second material tray, and there is a gap between the second arc-shaped baffle and the second material tray, and the gap forms a rubber ring feeding channel between the second arc-shaped baffle and the second material tray; the second bottom plate is located below the rubber ring feeding channel; the outlet of the rubber ring feeding channel is located between the sealing rod 9 and the support 7.

[0105] During operation, the rubber ring enters the rubber ring feeding channel from the entrance and is located in the rubber ring fixing groove 1. Then, the feed tray 2 rotates, driving the rubber ring to move within the rubber ring feeding channel and to the outlet of the rubber ring feeding channel. Because the rubber ring fixing grooves are arranged at equal intervals, the rubber rings can be separated by a certain gap, ensuring sufficient operating time between adjacent rubber rings, facilitating the operation of each rubber ring at the subsequent workstation.

[0106] Among them, such as Figure 7As shown, the unloading device 3 includes a material tray 301, an arc-shaped baffle 302 and a bottom plate 3; the material tray 301 is horizontally arranged and can rotate in the horizontal direction; a number of battery fixing grooves 2 303 are arranged at equal intervals on the side wall of the material tray 301; the battery fixing grooves 2 303 are vertically arranged and cover the entire circle of the material tray 301; the arc-shaped baffle 302 is located on the outside of the material tray 301, and there is a gap between the arc-shaped baffle 302 and the material tray 301, and the gap forms a battery discharge channel between the arc-shaped baffle 302 and the material tray 301; the bottom plate 3 is located below the battery discharge channel; the entrance of the battery discharge channel is located between the sealing rod 9 and the support 7.

[0107] During operation, the processed batteries are lifted and placed into the battery discharge channel through the entrance, where they are positioned in the second battery holding slot 303. The third material tray 301 then rotates, moving the batteries through the battery discharge channel and delivering them to the outlet. Because the second battery holding slots 303 are evenly spaced, they can separate the batteries by a certain amount, ensuring sufficient operating time between adjacent batteries, facilitating the operation of each battery at subsequent workstations.
