Description

Technical Field

[0001] The present application relates to the field of battery manufacturing technology, and in particular to a nickel-hydrogen battery full-tab positive electrode collector plate welding device. Background Art

[0002] Currently, nickel-metal hydride batteries require a current collector plate installed at each end to facilitate welding and electrical conductivity to the battery electrode assembly. Before assembly, the collector plate is a flat metal sheet consisting of a circular surface and a rectangular strip positioned on one side of the circular surface. The rectangular strip is bent, and the circular surface is welded to the positive end of the electrode assembly.

[0003] The traditional production process for battery collector plates involves welding first, followed by manual bending. During the bending process, uneven force applied each time results in varying bending angles for each finished conductive sheet. Furthermore, the difficulty in manual control can easily lead to welded conductive sheets becoming detached.

[0004] To address the above issues, automated equipment is currently available for automatic welding and bending of collector plates. However, when the collector plates and pole groups are aligned and connected, the current equipment has an unstable connection state, resulting in a high welding defect rate, which is not conducive to reducing production costs.

DETAILED DESCRIPTION

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0051] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0052] Please refer to Figure 1 、 Figure 2 and Figure 3The present embodiment provides a nickel-metal hydride battery full-tab positive electrode collector plate welding device 100, comprising a workbench 110, and a first turntable 120, an electrode group feeding assembly 130, an electrode group transporting and shaping assembly 140, a collector plate feeding assembly 150, a collector plate cutting assembly 160, a collector plate transporting assembly 170, an electrode group clamping assembly 122, a welding assembly 124, and a collector plate bending assembly 126 arranged on the workbench 110; the first turntable 120 comprises a first turntable 121 rotatably connected to the workbench 110, a plurality of limit sleeves 1212 are arranged in a circumferential array on the first turntable 121, and the electrode group feeding assembly 130 is used to hold the electrode group It is transferred to the pole group transfer and shaping component 140, and the pole group transfer and shaping component 140 transfers the pole group to the limiting sleeve 1212 and shapes the pole group; the collecting plate feeding component 150 is used to transfer the entire collecting plate to the collecting plate cutting component 160, and the collecting plate cutting component 160 is used to cut the entire collecting plate into individual collecting plates, and the collecting plate transfer component 170 transfers the individual collecting plates to the pole group and welds them through the welding component 124, wherein the welding component 124 is arranged in a one-to-one correspondence with the pole group clamping component 122 to clamp the pole group during welding, and the collecting plate bending component 126 is used to bend the welded collecting plate at a preset position.

[0053] Specifically, by arranging a plurality of limiting sleeves 1212 in a circular array on the first turntable 121, after the pole group is transferred to the limiting sleeves 1212, as the first turntable 121 rotates, the limiting sleeves 1212 on the first turntable 121 can respectively correspond to the collecting plate feeding assembly 150, the collecting plate cutting assembly 160, the collecting plate transfer assembly 170, the pole group clamping assembly 122, the welding assembly 124 and the collecting plate bending assembly 126, thereby realizing the gradual processing of the pole group.

[0054] During the process of welding the current collecting plate to the pole group, the pole group is shaped by the pole group transfer and shaping assembly 140. When the shaped pole group is moved to the work station where the current collecting plate transfer assembly 170 is located, the current collecting plate can better fit and align with the pole group. At this time, using the welding assembly 124 for welding is conducive to ensuring the stability of the welding.

[0055] The nickel-metal hydride battery full-ear positive collector plate welding equipment 100 provided in the embodiment of the present application is provided by a first turntable 120 provided on a workbench 110, a first turntable 121 of the first turntable 120 is rotatably connected to the workbench 110, and a limiting sleeve 1212 provided in a circumferential array on the first turntable 121 is used to load the pole group. In the process of driving the pole group to rotate, the pole group is made to correspond to different workstations to realize the processing of the pole group. The use of the rotation form can make the mutual arrangement more compact and reduce the occupied area compared with the long strip transmission form. During the processing, the pole group is first transferred to the pole group transfer and shaping component 140 by the pole group feeding component 130, and the pole group transfer and shaping component 140 transfers the pole group to the limiting sleeve 1212 and shapes the pole group. The shaped pole group is transferred to the next workstation under the drive of the first turntable 121. At the same time, the collecting disc feeding assembly 150 is also working, and the collecting disc cutting assembly 160 and the collecting disc transfer assembly 170 are used to cut the entire collecting disc into individual collecting discs and transfer them to the shaped pole group, so as to better match the shaped pole group. After the pole group and the collecting disc are aligned and fitted, the welding assembly 124 welds the two together, and then the welding collecting disc is bent by the collecting disc bending assembly 126 to facilitate the subsequent steel shell installation process. Using the above method, when the collecting disc is welded to the pole group, the pole group is shaped, which is conducive to ensuring the stability of the fitting, and can improve the yield rate of automatic welding, thereby reducing production costs.

[0056] like Figure 1 、 Figure 2 and Figure 4 As shown, the workbench 110 is also provided with a second turntable 180, a steel shell feeding assembly 190, a steel shell transfer assembly 183, a pressing assembly 184 and a steel shell discharging assembly 186; the second turntable 180 includes a second turntable 181 rotatably connected to the workbench 110, and a plurality of positioning supports 1812 are arranged in a circular array on the second turntable 181. The workbench 110 is also provided with a transfer robot 112 for transferring the pole group in the limiting sleeve 1212 to the positioning support 1812; the steel shell feeding assembly 190 is used to transfer the steel shell to the steel shell transfer assembly 183, the steel shell transfer assembly 183 is used to transfer the steel shell to the positioning support 1812, the pressing assembly 184 is used to press the pole group transferred to the positioning support 1812 into the steel shell, and the steel shell discharging assembly 186 is used to transport the steel shell after being pressed into the pole group.

[0057] Specifically, after the electrode assembly and the current collecting disc are welded together and the portion of the current collecting disc extending beyond the electrode assembly is bent, the electrode assembly is transferred to the second turntable 181 of the second turntable 180 by a transfer robot 112, where it engages with positioning brackets 1812 arranged in a circular array on the second turntable 181. The transfer robot 112 can be a PPU robot, which can replace traditional pneumatic or electric modules. Driven by a servo or stepper motor, the object can move along a predetermined trajectory, making the entire gripping process faster and improving production efficiency.

[0058] During the process of transferring the electrode assembly to the positioning tray 1812, the steel shell feeding assembly 190 simultaneously transfers the steel shell to the steel shell transfer assembly 183. The steel shell transfer assembly 183 then transfers the steel shell to the positioning tray 1812. The electrode assembly is aligned with the positioning tray 1812 with the steel shell inside. The pressing assembly 184 presses the electrode assembly into the steel shell. The steel shell, after being pressed into the electrode assembly, is then transferred to the next process. The entire process is completed by the coordination of the various components and does not require any human intervention.

[0059] like Figure 3 As shown, the first turntable 120 also includes a first support 123 arranged on the workbench 110, and a first cam divider 1232 and a first driver 1234 arranged on the first support 123. The first driver 1234 is transmission-connected to the first cam divider 1232, and the output end of the first cam divider 1232 is connected to the first turntable 121.

[0060] Specifically, the first turntable 120 is connected to the workbench 110 via the first support 123. This allows the first turntable 120 to be assembled first and then assembled with the workbench 110, which improves assembly efficiency. Furthermore, the provision of a first cam divider 1232 on the first support 123 enables high-precision rotation, ensuring precise alignment between the stop sleeve 1212 on the first turntable 121 and each component.

[0061] like Figure 5 and Figure 6 As shown, the pole group feeding assembly 130 includes a first bracket 132 arranged on the workbench 110 or the first bracket 123, and a first conveyor belt assembly 134 arranged on the first bracket 132; the pole group transfer and shaping assembly 140 includes a first support plate 142 arranged on the first bracket 123, and a pushing assembly 144, a pressing assembly 146 and a first shaping assembly 148 arranged on the first support plate 142. The pushing assembly 144 is docked with the first transmission belt assembly to push the pole group to the top of the limit sleeve 1212, the pressing assembly 146 is used to press the pole group into the limit sleeve 1212, and the first shaping assembly 148 is used for the initial shaping of the pole group.

[0062] Specifically, a first conveyor belt assembly 134 is provided on the first bracket 132 to facilitate the sequential forward conveyance of the electrode assembly. It is understood that, during the conveyance process, to prevent the electrode assembly from accidentally falling, a protective plate can be installed at the corresponding position of the first conveyor belt assembly 134. After the electrode assembly is transferred to the electrode assembly transfer and shaping assembly 140, a pusher assembly 144 provided on the first support plate 142 pushes the electrode assembly above the limiting sleeve 1212. The pushing direction of the pusher assembly 144 and the conveying direction of the first conveyor belt assembly 134 form a preset angle, thereby facilitating the rational layout of the various components within the limited space and improving their relative compactness. After the electrode assembly is pushed above the limiting sleeve 1212, to ensure a stable relative position between the electrode assembly and the limiting sleeve 1212, a pressing assembly 146 is used to press the electrode assembly into the limiting sleeve 1212. At this point, the first shaping assembly 148 performs the initial shaping of the electrode assembly, thereby making the outer circle of the electrode assembly and the end surface corresponding to the current collecting disk more regular.

[0063] like Figure 6 As shown, a guide assembly 145 is also provided on the first support plate 142, and the guide assembly 145 includes a first lifting cylinder 1452 provided on the support plate, and a guide sleeve 1454 connected to the first lifting cylinder 1452, and the guide sleeve 1454 can pass through the first support plate 142 and correspond to the limit sleeve 1212; the pushing assembly 144 includes a first propulsion cylinder 1442 provided on the first support plate 142, and a first push block 1444 connected to the first propulsion cylinder 1442, and a notch 1454a is provided on the side of the guide sleeve 1454 so that the first push block 1444 pushes the pole group into the guide sleeve 1454; the pressing assembly 146 includes a second lifting cylinder 1462 provided on the first support plate 142, and a first pressure head 1464 connected to the second lifting cylinder 1462.

[0064] Specifically, due to a certain height difference between the plane on which the electrode assembly is conveyed and the limiting sleeve 1212, to ensure that the electrode assembly can smoothly enter the limiting sleeve 1212, a guide sleeve 1454 is provided on the first support plate 142 corresponding to the limiting sleeve 1212. When the electrode assembly is pushed by the first push block 1444, the electrode assembly enters the guide sleeve 1454 through the notch 1454a. Under the downward pressure of the first pressing head 1464, the electrode assembly slides along the guide sleeve 1454 into the limiting sleeve 1212. After the electrode assembly is loaded into place, to prevent the guide sleeve 1454 from affecting the normal rotation of the first turntable 121, the guide sleeve 1454 can be lifted by the first lifting cylinder 1452 by a preset distance.

[0065] like Figure 6As shown, the first shaping assembly 148 includes a first clamping cylinder 1482 and a third lifting cylinder 1484 arranged on the first support plate 142. The first clamping cylinder 1482 is connected to a first clamping block 1486 for clamping the circumferential side wall of the pole group. The third lifting cylinder 1484 is connected to a first shaping head 1488. The first shaping head 1488 includes a pressure plate 1488a and an annular retaining wall 1488b arranged on the pressure plate 1488a.

[0066] Specifically, by providing a first clamping cylinder 1482 on the first support plate 142 and connecting a first clamping block 1486 to the first clamping cylinder 1482, when shaping the electrode group, the outer ring of the electrode group that is exposed from the limiting sleeve 1212 can be first clamped by the first clamping block 1486. Then, when the electrode group is shaped by the first shaping head 1488, the stability of the shaping process is ensured and damage to the electrode group can be avoided. The pressure plate 1488a of the first shaping head 1488 is used to shape the top surface of the electrode group, while the annular retaining wall 1488b is used to shape the outer circle of the electrode group.

[0067] like Figure 7 As shown, the nickel-hydrogen battery full-pole tab positive collector plate welding equipment 100 also includes a second shaping component 149, and the second shaping component 149 includes a second clamping cylinder 1492 and a fourth lifting cylinder 1494 arranged on the first support 123. The second clamping cylinder 1492 is connected to a second clamping block 1496 for clamping the circumferential side wall of the pole group, and the fourth lifting cylinder 1494 is connected to a second shaping head 1498 for secondary shaping of the pole group.

[0068] Specifically, by providing a second clamping cylinder 1492 on the first support 123 and connecting a second clamping block 1496 to the second clamping cylinder 1492, when shaping the electrode assembly, the outer ring of the electrode assembly exposed from the limiting sleeve 1212 can first be clamped by the second clamping block. Subsequently, when the electrode assembly is shaped by the second shaping head 1498, the stability of the shaping process is ensured and damage to the electrode assembly is avoided. The second shaping head 1498 is primarily used for secondary shaping of the top surface of the electrode assembly, in preparation for subsequent mating with the collecting plate, to ensure the reliability of the mating.

[0069] like Figure 8 and Figure 9As shown, the collecting tray feeding assembly 150 includes a collecting tray loading assembly 152 and a collecting tray conveying assembly 154 respectively arranged on the workbench 110; the collecting tray loading assembly 152 includes a first bracket 1522 arranged on the workbench 110, and a second driver 1524 and a first arc-shaped guide plate 1526 arranged on the first bracket 1522, a discharge tray 1527 is connected to the second driver 1524, and a limit frame 1528 is provided on the convex side of the first arc-shaped guide plate 1526; the collecting tray conveying assembly 154 includes a second bracket 1542 arranged on the workbench 110, and the second bracket 1542 is provided with a slide rail 1543, a first feeding support plate 1544 and a second arc-shaped guide plate Plate 1545, the second arc-shaped guide plate 1545 corresponds to the first arc-shaped guide plate 1526, and is docked with the first feeding support plate 1544. The slide rail 1543 is slidably connected with a first sliding seat 1546, and the first sliding seat 1546 is provided with a first lifting cylinder 1547, and the first lifting cylinder 1547 is connected with a thimble, which is used to pass through the through hole on the collecting plate. The second bracket 1542 is also provided with a second propulsion cylinder 1548 connected with the first sliding seat 1546, and a limiting cylinder 1549 corresponding to the second arc-shaped guide plate 1545, and the limiting cylinder 1549 is connected with a second pressure head 1549a, and the second pressure head 1549a can move toward or away from the second arc-shaped guide plate.

[0070] Specifically, by providing a second driver 1524 on the first bracket 1522 and providing a discharge tray 1527 connected to the second driver 1524 on the first support, when a rolled current collecting tray is loaded into the discharge tray 1527, the second driver 1524 can drive the discharge tray 1527 to rotate to ensure smooth discharge. In addition, by providing a first curved guide plate 1526 on the first bracket 1522, the entire current collecting tray can be guided to facilitate normal feeding. At the same time, by providing a limit frame 1528 on the convex side of the first curved guide plate 1526, the current collecting tray can be limited when it passes through the limit frame 1528, thereby ensuring the stability of the relative position relationship between the current collecting tray and the first curved guide plate 1526.

[0071] To ensure smooth docking between the collecting tray loading assembly 152 and the collecting tray conveying assembly 154, a second curved guide plate 1545 is provided on the second bracket 1542, corresponding to the first curved guide plate 1526. The second curved guide plate 1545 docks with the first feeding pallet 1544, facilitating the transfer of the collecting tray to the first feeding pallet 1544. To move the collecting tray forward, the first lifting cylinder 1547 is activated, allowing the ejector pin to pass through the through-hole in the collecting tray and engage the collecting tray. The second propulsion cylinder 1548 is then activated, driving the first lifting cylinder 1547 forward as a whole, simultaneously moving the collecting tray. In addition, by arranging a limiting cylinder 1549 on the second bracket 1542 and connecting a second pressure head 1549a to the limiting cylinder 1549, the collecting plate can be pressed onto the second arc-shaped guide plate 1545 when cutting the collecting plate, which can avoid vibration and deviation during the cutting process of the collecting plate, and is conducive to ensuring the stability of subsequent transmission.

[0072] like Figure 10 and Figure 11 As shown, the collecting plate cutting assembly 160 includes a support 162 and a second lifting cylinder 164 arranged on the workbench 110, a guide column 165 is slidably connected to the support 162, and a connecting seat 166 is arranged on the guide column 165, a pressure block 167 and an upper cutter 168 are arranged on the connecting seat 166, and the second lifting cylinder 164 is connected to the guide column 165 to drive the connecting seat 166 to move up and down; the support 162 is also provided with a second feeding support plate 169 corresponding to the first feeding support plate 1544 and the pressure block 167 respectively, and a lower cutter 163 corresponding to the upper cutter 168, and the support 162 is also provided with a support block 1622, which is used to receive the cut collecting plate.

[0073] Specifically, as the collector plate passes through the second feed tray 169, the second lifting cylinder 164 forces the connecting base 166 toward the second feed tray 169, driving the pressing block 167 and the cutter blades to move synchronously. While the pressing block 167 presses the collector plate against the second feed tray 169, the upper cutter 168 and lower cutter 163 cut the collector plate into individual pieces. Furthermore, a support block 1622, mounted on the support 162, receives the cut collector plate, facilitating its transport via the collector plate transfer assembly 170.

[0074] like Figure 12As shown, the collecting plate transfer assembly 170 includes a mounting base 171 arranged on the workbench 110, a first drive motor 172 arranged on the mounting base 171, and a support arm 173 arranged on the connecting base 166, the support arm 173 is provided with a first bearing seat 174, and the mounting base 171 is also provided with a second bearing seat 175 corresponding to the first bearing seat 174, a rotating shaft 176 is rotatably connected between the first bearing seat 174 and the second bearing seat 175, the rotating shaft 176 is transmission-connected to the first drive motor 172, a swing arm 177 is provided on the rotating shaft 176, and a magnetic suction part 178 is provided at the end of the swing arm 177 to transfer the cut collecting plate to the pole group; the rotating shaft 176 is connected to the second bearing seat 175 through a shaft sleeve, and the rotating shaft 176 and the shaft sleeve are slidingly connected.

[0075] Specifically, when transporting the cut-off current collecting disc, the first drive motor 172 drives the swing arm 177 to rotate within a preset angle so that the current collecting disc is transported from the support block 1622 to the pole group. In addition, by connecting the support arm 173 to the connecting seat 166, the support arm 173 will be driven to rise and fall synchronously during the lifting and lowering process of the connecting seat 166. At this time, the swing arm 177 will also rise and fall synchronously. In the process of cutting off the current collecting disc, the magnetic part 178 provided on the swing arm 177 follows the connecting seat 166 to be pressed down, and is attracted by the magnetic part 178 at the moment the current collecting disc is cut off. After the current collecting disc is cut off, the swing arm 177 rises with the connecting seat 166, and under the action of the first drive motor 172, the current collecting disc is transported to the pole group, and is welded and fixed by the welding assembly 124.

[0076] Among them, the second bearing seat 175 arranged on the mounting seat 171 is fixed relative to the mounting seat 171. When the rotating shaft 176 and the second bearing seat 175 slide relative to each other, in order to ensure the stability of the connection, the rotating shaft 176 can be connected to the second bearing seat 175 through a shaft sleeve, and a sliding groove is provided on the inner side of the shaft sleeve, and a sliding key is provided on the rotating shaft 176 to achieve the required relative sliding.

[0077] like Figure 13 and Figure 14As shown, the pole group clamping assembly 122 includes a first base 1222 arranged on the first turntable 121 or on the first support 123, and a third propulsion cylinder 1224 arranged on the first base 1222. A limiting seat 1225 is also provided on the first base 1222, and a first rack 1226 and a second rack 1227 are slidably connected in the limiting seat 1225, and a gear rotatably connected to the limiting seat 1225, the gear is located between the first rack 1226 and the second rack 1227, and is respectively engaged with the first rack 1226 and the second rack 1227, a first clamping block 1228 is provided on the first rack 1226, and a second clamping block 1229 corresponding to the first clamping block 1228 is provided on the second rack 1227, the first rack 1226 or the second rack 1227 is connected to the third propulsion cylinder 1224 so that the first clamping block 1228 and the second clamping block 1229 are relatively close to or far away from each other.

[0078] Specifically, the third propulsion cylinder 1224 provided on the first base 1222 is used as an example to illustrate the third propulsion cylinder 1224 and the first rack 1226. When the third cylinder is actuated, the first rack 1226 is driven to actuate synchronously. Since the first rack 1226 and the second rack 1227 are connected by a gear, when the first rack 1226 slides relative to the limit seat 1225, the second rack 1227 slides in the opposite direction relative to the limit seat 1225. This allows the first clamping block 1228 and the second clamping block 1229 to move closer to or further away from each other, thereby clamping or releasing the electrode assembly.

[0079] It can be understood that when the first rack 1226 and the second rack 1227 are respectively engaged with the gears, the length of the first rack 1226 or the second rack 1227 extended is different depending on the initial engagement position. The initial engagement position can be adjusted according to actual needs so that the pole group can be better fitted when clamping to ensure stable subsequent welding.

[0080] like Figure 15 and Figure 16 As shown, the welding assembly 124 includes a top plate 1242 arranged on the first support 123, and a second base 1244 arranged on the top plate 1242, the second base 1244 is provided with a welding cylinder 1245, and a second sliding seat 1246 slidably connected to the second base 1244, and the welding cylinder 1245 is connected to the second sliding seat 1246 to drive the second sliding seat 1246 to slide relative to the second base 1244, the second sliding seat 1246 is connected to a clamp 1247, and the clamp 1247 is connected to a welding needle 1248.

[0081] Specifically, the top plate 1242 disposed on the first support 123 facilitates positioning of the second base 1244, thereby facilitating better alignment of the welding needle 1248 with the electrode assembly. When welding the current collecting plate, the welding cylinder 1245 drives the second slide to slide along the second base 1244, and the welding needle 1248 moves synchronously with the second slide until the welding needle 1248 contacts the current collecting plate, thereby completing the welding process.

[0082] It should be noted that the welding assemblies 124 are provided in multiple groups, one of which corresponds to the current collecting tray transfer assembly 170. When the current collecting tray is transferred to the top of the electrode group, it is initially welded and fixed. The other welding assemblies 124 correspond to different positions of the current collecting tray through welding needles 1248, thereby realizing batch welding at different positions of the current collecting tray.

[0083] like Figure 17 As shown, the collecting plate bending assembly 126 includes a paddle assembly and a shaping assembly, the paddle assembly is used to bend the protruding end of the collecting plate upward, and the shaping assembly includes a third base 1262 arranged on the first support 123 or the workbench 110, and a first cylinder 1263 and a second cylinder 1264 arranged on the third base 1262, the pushing directions of the first cylinder 1263 and the second cylinder 1264 are perpendicular to each other, the first cylinder 1263 is connected to a first push head 1265, and the second cylinder 1264 is connected to a second push head 1266, the first push head 1265 is provided with a first guide slope, and the second push head 1266 is provided with a second guide slope corresponding to the first guide slope.

[0084] Specifically, the paddle assembly can use a motor to drive a cam, and a lever is provided at the edge of the cam to bend the extended end of the collecting plate upward. Then, the first cylinder 1263 and the second cylinder 1264 of the shaping assembly are operated to clamp the bent position between the first guide bevel and the second guide bevel, thereby achieving the desired bending angle.

[0085] like Figure 4 and Figure 18 As shown, the second turntable 180 also includes a second support 182 arranged on the workbench 110, and a second cam divider 1822 and a third driver 1824 arranged on the second support 182. The third driver 1824 is transmission-connected to the second cam divider 1822, and the output end of the second cam divider 1822 is connected to the second turntable 181.

[0086] Specifically, the second turntable 180 is connected to the workbench 110 via the second support 182. This allows the second turntable 180 to be assembled first and then assembled with the workbench 110, which improves assembly efficiency. Furthermore, the second cam divider 1822 provided on the second support 182 enables high-precision rotation, ensuring precise alignment between the stop sleeve 1212 on the second turntable 181 and each component.

[0087] like Figure 18 、 Figure 19 and Figure 20 As shown, the steel shell feeding assembly 190 includes a second bracket 192 arranged on the workbench 110, and a second conveyor belt assembly 194 arranged on the second bracket 192; the steel shell transfer assembly 183 includes a first pushing cylinder 1832 and a first slide 1834 arranged on the second bracket 182, the first slide 1834 corresponds to the second conveyor belt assembly 194 and the positioning support 1812 respectively, and the first pushing cylinder 1832 is connected to the second pushing block 1836 so that the steel shell transferred to the first slide 1834 slides to the positioning support 1812 under the pushing action of the second pushing block 1836.

[0088] Specifically, by installing a second conveyor belt assembly 194 on the second bracket 192, the steel shells are conveniently conveyed forward in sequence. It is understood that during the conveying process, in order to prevent the steel shells from accidentally falling, a protective plate can be installed at the corresponding position of the second conveyor belt assembly 194. After the steel shells are conveyed to the steel shell transfer assembly 183, the first pushing cylinder 1832 pushes the steel shells forward in sequence along the first slide 1834, and finally pushes the steel shells to the positioning support 1812.

[0089] like Figure 21 As shown, the pressing assembly 184 includes a pressing cylinder 1842 disposed on the second support platform 182 , and a third pressing head 1844 connected to the pressing cylinder 1842 , and the third pressing head 1844 corresponds to the positioning support 1812 .

[0090] In this way, after the steel shell is inside the positioning tray 1812, the transfer robot 112 transfers the electrode assembly to the top of the positioning tray 1812. Under the action of the pressing cylinder 1842, the third pressing head 1844 applies pressure to the electrode assembly to press the electrode assembly into the steel shell.

[0091] like Figure 22As shown, the steel shell discharging assembly 186 includes a second slide 1862, a second pushing cylinder 1864 and a third pushing cylinder 1866 arranged on the second support platform 182, wherein the second slide 1862 is provided with an opening 1862a corresponding to the positioning support 1812, the second pushing cylinder 1864 is connected to a magnetic head 1865 to allow the steel shell to be adsorbed into the second slide 1862, and the third pushing cylinder 1866 is connected to a third pushing block 1867 for pushing the steel shell in the second slide 1862 forward.

[0092] Specifically, after the pole assembly is pressed into the steel shell, second push cylinder 1864 pushes forward, driving magnetic head 1865 to move to positioning support 1812 and absorb the steel shell. As second push cylinder 1864 resets, magnetic head 1865 drives the steel shell through opening 1862a toward second slide 1862. Once there, it is stopped by the sidewalls of second slide 1862, allowing the steel shell to fall into the second slide 1862. At this point, third push cylinder 1866, via third push block 1867, pushes the steel shell forward, enabling discharge of the steel shell.

[0093] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
