DETAILED DESCRIPTION

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0038] The present invention will be further described below with reference to the embodiments.

[0039] Example 1

[0040] A sodium ion battery assembly device, such as Figures 1 to 11 As shown, it includes a gluing workbench 1, a gluing component 2 and an assembly component 3. The gluing workbench 1 is located at the upper side of the assembly component 3. The gluing component 2 includes a linear motor 201 and a moving seat 202 fixedly installed at the bottom of the moving end of the linear motor 201. The bottom of the moving seat 202 is fixedly connected to a moving frame 203 through an electric hydraulic push rod. The top of the gluing workbench 1 is fixedly connected to a guide plate 207 and a plurality of dividing plates 223. The dividing plate 223 is embedded with a battery gluing nozzle 224.

[0041] A fixed clamping plate 204 is fixedly installed on the bottom edge of the mobile frame 203, and a movable clamping plate 205 corresponding to the fixed clamping plate 204 is rotatably connected to the mobile frame 203. After the movable clamping plate 205 rotates, it works together with the fixed clamping plate 204 to complete the left and right clamping work. A clamping plate push rod 208 is fixedly connected to one side of the mobile frame 203, and the output end of the clamping plate push rod 208 is fixedly connected to a clamping plate 209. The clamping plate 209 works together with the side plate of the mobile frame 203 to complete the front and back clamping of the battery;

[0042] The assembly component 3 includes an assembly table 301, two side panel accommodating boxes 307 for accommodating side panels, two end panel accommodating boxes 302 for accommodating end panels, and a bottom panel accommodating box 312 for accommodating the bottom panel. The movable rack 203 holding the battery moves to the top of the assembly table 301 and then moves downward, and the battery is placed on the assembly table 301 to complete the assembly of the side panels, end panels and bottom panel.

[0043] A guide plate 2231 with an inclined surface is distributed on one side of the dividing plate 223 to guide the battery to move obliquely. The guide plate 207 is located at the far end of the dividing plate 223 and is distributed obliquely, corresponding to the guide plate 2231 of the dividing plate 223. After the battery passes through the dividing plate 223 and the guide plate 207, glue is applied between the batteries and on the outside of the battery cells on both sides of the battery pack.

[0044] Taking the gluing workbench 1 or the gluing assembly 2 in the figure as the viewing angle reference, the battery cells or battery cores need to be neatly pushed from the left side to between the clamping plate 209 and the movable rack 203, and then the linear motor 201 is started to move the movable rack 203 toward the assembly component 3. In this process, the side plates of the movable rack 203 push the battery cells or battery cores and contact with multiple dividing plates 223. The battery cells or battery cores are gradually dispersed between the various dividing plates 223 from a closely attached state. In this process, the dividing plates 223 and the battery gluing nozzles 224 on the guide plates 207 perform the gluing work and apply glue to the sides of the battery cells or battery cores. After the gluing work is completed, the movable splint 205 is rotated by the motor, pushing the left side of the battery cell or battery core coated with glue and clamping it together, then starting the splint push rod 208 to align the battery cell or battery core in the front and rear directions, so that the battery cell or battery core is tightly and regularly arranged under the movable rack 203. After the battery cell or battery core is moved to the assembly component 3, it is connected to the side plate, end plate and bottom plate to complete the subsequent assembly of the battery pack. In this way, the glue does not need to be applied in sequence. After the application is completed, the battery cell or battery core can be quickly aligned, and the glue can be cured in the aligned state.

[0045] A plurality of groups of dial plates 211 are slidably inserted on the gluing workbench 1. In each group of dial plates 211, the number of dial plates 211 is two, and the bottom ends of the two dial plates 211 in the same group are rotatably connected to the connecting seat 210. A spring is fixedly connected between the two dial plates 211. A plurality of mounting brackets 212 are fixedly installed on the bottom of the gluing workbench 1. A dial push rod 213 is fixedly connected to the mounting bracket 212. The bottom of the gluing workbench 1 is rotatably connected to an extrusion plate 214 through a rotating rod. The extrusion plate 214 is located below the connecting seat 210. The dial push rods 213 are respectively distributed at both ends of the extrusion plate 214, and the dial push rods 213 need to be started in sequence.

[0046] When the battery cell or battery core is ready to pass through between the dividing plate 223 and the guide plate 207, the dividing push rod 213 needs to be started in sequence. Since the battery cell or battery core will be pushed onto the side wall of the fixed splint 204 when placed, the dividing push rod 213 close to the fixed splint 204 needs to be started first. In the process of the output end of the dividing push rod 213 gradually rising upward, one end of the extrusion plate 214 is gradually squeezed upward. At this time, the closer the dividing plate 211 is to the fixed splint 204, the higher the rising height is, that is, the battery cell or battery core closer to the extrusion plate 214 will be inserted into the dividing plate 211 sooner. During the process, the battery cells or battery cells will gradually spread out due to the squeezing of the distribution plate 211, and the spreading distance will be increased under the elastic support of the spring between the distribution plates 211. Then another distribution push rod 213 is started to gradually raise the other end of the squeezing plate 214. The squeezing of the connecting seat 210 by the squeezing plate 214 allows the remaining connecting seats 210 to be inserted between the battery cells or battery cells in turn, so that the battery cells or battery cells are in a dispersed state when passing through the distribution plate 223, avoiding direct contact between the battery cells or battery cells and the distribution plate 223, causing damage to the battery cells or battery cells.

[0047] The bottom of the gluing workbench 1 is fixedly connected to an insulating plate accommodating box 215 for accommodating insulating plates. Slots for the insulating plates to pass through are provided at both side ends of the inner wall of the insulating plate accommodating box 215. Two slots for the insulating plates to pass through are provided at the positions corresponding to the dividing plate 223 and the end of the gluing workbench 1. After the battery passes through the dividing plate 223 and the guide plate 207, it is located between the two slots of the gluing workbench 1. A lifting push rod 216 is fixedly connected to the mounting frame 212. The output end of the lifting push rod 216 is fixedly connected to the lifting plate 217. The lifting plate 217 is slidably installed in the slot of the insulating plate accommodating box 215. Two support plates 218 are slidably connected in the insulating plate accommodating box 215. A spring is fixedly connected between the two support plates 218. A rotating door 219 is hinged on one side of the insulating plate accommodating box 215. After the hinged rotating door 219 is opened, the insulating plate is filled into the insulating plate accommodating box 215.

[0048] In the process of the battery cell or battery cell passing through the dividing plate 223 and the guide plate 207, the ejecting push rod 216 under the insulating plate accommodating box 215 is started, and the insulating plate in the insulating plate accommodating box 215 is ejected from the slot by pushing the ejecting plate 217 upward, and is placed above the gluing workbench 1. After the battery cell or battery cell to be glued is moved between the two slots of the gluing workbench 1, the movable splint 205 is rotated by the drive of the motor to clamp the insulating plate and the battery cell or battery cell together. Due to the setting of the guide plate 207, glue is applied to both ends of the battery cell or battery cell at this time, so the insulating plate can be glued to the battery cell or battery cell without glue. With the cooperation of the movable splint 205 and the fixed splint 204, the insulating plate and the battery cell or battery cell can be tightly clamped together, and the next step can be entered after the glue is dried.

[0049] The top of the gluing workbench 1 is fixedly connected with two fixed rubber strips 220 and two fixed plates 221, and the fixed rubber strips 220 and the fixed plates 221 are distributed near the two ends of the slot of the gluing workbench 1. The bottom end of the fixed plate 221 is rotatably connected with a movable rubber strip 222, and a spring is fixedly connected between the movable rubber strip 222 and the fixed plate 221.

[0050] During the rising process of the insulating plate, the edge of the insulating plate will contact the fixed rubber strip 220 and the movable rubber strip 222 in an inclined state. Under the elastic support of the spring between the movable rubber strip 222 and the fixed plate 221, the insulating plate is clamped between the movable rubber strip 222 and the movable rubber strip 222, completing a simple fixing effect. After the movable clamping plate 205 rotates, the insulating plate is clamped on both sides of the battery cell or battery core.

[0051] Example 2, based on Example 1, Figures 11 to 16 As shown,

[0052] The end plate accommodating box 302 is above the bottom plate accommodating box 312. The top of the end plate accommodating box 302 is fixedly connected to the insulating plate glue coating nozzle 303 for coating the insulating plate. The fixed splint 204 and the movable splint 205 are both provided with slots corresponding to the end plates, and a sliding groove for the insulating plate glue coating nozzle 303 to pass through is provided in the middle of the slot. Both sides of the end plate accommodating box 302 are rotatably connected to the rotating plate 304 through a torsion spring. The rotating plate 304 is fixedly connected to the movable plate 305 by bolts. The end of the movable plate 305 is fixedly connected to the limiting plate 306. The end plate accommodating box 302 is vertically slidably connected to a push plate, and the push plate The end plate 302 is fixedly connected with a spring, and the limit plate 306 cooperates with the push plate to clamp the end plate in the end plate accommodating box 302, and under the pushing force of the spring on the limit plate 306, the end plate is outside the end plate accommodating box 302. When the fixed splint 204 and the movable splint 205 move downward, they are inserted between the two end plates so that the end plate is in the end plate accommodating groove 206 of the fixed splint 204 and the movable splint 205, and as the fixed splint 204 and the movable splint 205 move downward, the rotating plate 304 and the movable plate 305 gradually rotate downward and lose the clamping effect on the end plate in the end plate accommodating box 302.

[0053] After the glue is dried, the linear motor 201 is started, and the movable seat 202 is moved to the top of the assembly component 3. An end plate receiving groove 206 for accommodating the end plate position is opened on the fixed splint 204. Under the action of the push plate in the end plate receiving box 302, the end plate slides outward and is clamped between the push plate and the limit plate 306. The electric hydraulic push rod on the movable seat 202 is started, and the movable frame 203 and the battery cells or cells below the movable frame 203 after the glue is dried are lowered together. In this process, the fixed splint 204 and the movable splint 205 will be inserted between the end plates, so that the end plates are kept in the ejection push rod 216. At the same time, during the downward movement, the insulating plate glue coating nozzle 303 on the top of the end plate accommodating box 302 will pass through the slide groove in the end plate accommodating groove 206 to apply glue to the insulating plates at both ends of the battery cell or battery core, and as the end plate gradually overlaps with the insulating plate, the end plate and the insulating plate are bonded together. At the same time, during the downward movement of the fixed clamping plate 204 and the movable clamping plate 205, the rotating plate 304 and the movable plate 305 gradually rotate downward, and the limit plate 306 loses its grip on the end plate. After the rotating plate 304 and the movable plate 305 are completely flipped over, the installation of the end plate is completed, and the end plate can be quickly installed on the insulating plate.

[0054] The bottom plate accommodating box 312 is fixedly connected with a bottom plate push rod 313, the output end of the bottom plate push rod 313 is fixedly connected with a discharge plate 314, the side plate accommodating box 307 is slidably connected with a push plate 318, the top of the side plate accommodating box 307 is fixedly connected with two bases 309, one end of the base 309 is rotatably connected to an angle limiting plate 310 through a torsion spring, the top of the base 309 is fixedly connected with an elastic sheet 311, the top of the assembly table 301 is fixedly connected with two accommodating box push rods 308, the output ends of the two accommodating box push rods 308 are respectively fixedly connected to the side walls of the two side plate accommodating boxes 307, the bottom of the side plate accommodating box 307 is provided with a slot for the battery pack bottom plate to pass through, and the bottom of the outer walls on both sides of the side plate accommodating box 307 are rotatably connected with a retaining plate 317 through a torsion spring.

[0055] Before the battery cells or battery cells are lowered with the mobile rack 203, the bottom plate push rod 313 in the bottom plate accommodating box 312 is needed to push out the battery pack bottom plate in the bottom plate accommodating box 312. The battery pack side plates in the side plate accommodating box 307 will extend outward under the action of the pushing plate 318 and its spring, and the battery pack side plates are restricted by the retaining plate 317. In the process of the battery pack bottom plate gradually moving outward, the short side plates on both sides of the U-shaped battery pack bottom plate will be inserted between the battery pack side plates, and then the output end of the accommodating box push rod 308 will retract, allowing the two side plate accommodating boxes 307 to move away from each other. At this time, the battery pack side plates will rotate under the restriction of the side plates of the battery pack bottom plate, and will be pressed against the battery pack by the torsion spring on the retaining plate 317. On the bottom plate, as the electric hydraulic push rod on the movable seat 202 continues to move downward, the battery cells or battery cells will contact the two inclined battery pack side panels. Since the battery pack side panels are between the battery cells or battery cells and the side panels of the battery pack bottom plate, the battery pack side panels are forced to be in a vertical state through squeezing. As the battery pack side panels gradually become vertical, the battery pack side panels will exceed the restriction of the angle limiting plate 310, causing the elastic sheet 311 to deform. In this process, the angle limiting plate 310 increases the contact with the battery pack side panels and provides additional pressure. Combined with the elasticity of the torsion spring on the retaining plate 317, the battery pack side panels remain tilted and will not hinder the descent of the battery cells or battery cells. As a result, the installation of the bottom plate and side panels of the battery pack can be completed quickly, thereby improving work efficiency.

[0056] Example 3, based on Example 1 or 2, Figure 11 As shown,

[0057] Both sides of the assembly platform 301 are fixedly connected with driving push rods 316 , and welding guns 315 are installed on the output ends of the driving push rods 316 .

[0058] After the battery pack bottom plate and side plates are installed, the driving push rod 316 can be started to allow the welding gun 315 to weld the gap between the end plate and the battery pack side plate. Alternatively, a more intelligent robotic arm can be used to drive the welding gun 315 to complete the welding, which can further help improve work efficiency.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
