Description

Technical Field

[0001] This utility model relates to the field of battery electrolyte filling and settling, specifically to a differential pressure settling device. Background Technology

[0002] In the lithium battery production process, a differential pressure injection machine is typically used to inject electrolyte into the battery. To ensure that the electrolyte can penetrate the interior of the battery cell, the battery usually needs to be left to stand.

[0003] Currently, the settling equipment used for battery settling is usually a turntable structure. The settling modules of this turntable structure are usually arranged in a star shape. This structure makes the production workshop wider and the battery clamps take longer to move between adjacent settling modules, resulting in a longer overall settling time and reduced production efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a differential pressure settling device, which can reduce the width of the production workshop and reduce the overall settling time, thereby improving production efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A differential pressure settling device includes a first settling line, a second settling line, and a conveying device. The first and second settling lines are arranged parallel to each other. The first settling line includes a first lifting module, a first starting settling module, an intermediate settling module, and an ending settling module connected sequentially from left to right. The first lifting module is used to convey battery clamps conveyed from the first conveyor line to the first starting settling module. The first starting settling module, the intermediate settling module, and the ending settling module are used sequentially to perform a first settling process, a second settling process, and a third settling process on a plurality of batteries in the battery clamps conveyed by the first lifting module. The second settling line includes a second lifting module and a second starting point settling module connected sequentially from left to right. The transport device is located at the right end of the end point settling module and the second starting point settling module. The transport device is used to transport the battery clamp to the second starting point settling module after the battery clamp has undergone a third settling process at the end point settling module. The second starting point settling module is used to perform a fourth settling process on the battery clamp that has been transported by the transport device. The second lifting module is used to transport the battery clamp to the second conveyor line after the battery clamp has undergone a fourth settling process at the second starting point settling module.

[0007] The beneficial effects of this utility model are as follows: By setting a first stationary line and a second stationary line, which are arranged in parallel front to back, the first lifting module, the first starting stationary module, the middle stationary module and the ending stationary module of the first stationary line are connected sequentially from left to right, and the second lifting module and the second starting stationary module of the second stationary line are connected sequentially from left to right. The linear structure can reduce the width of the production workshop and reduce the flow of battery clamps between adjacent stationary modules, thereby reducing the overall stationary time and improving production efficiency.

[0029] Please refer to Figure 1 and Figure 2 An embodiment of this utility model provides a differential pressure settling device, which includes a first settling line, a second settling line, and a conveying device 50.

[0030] The first and second stationary lines are arranged parallel to each other. The first stationary line includes a first lifting module 10, a first starting stationary module 20, an intermediate stationary module 30, and an ending stationary module 40 connected sequentially from left to right. The first lifting module 10 is used to transport the battery clamp 200 conveyed from the first conveyor line to the first starting stationary module 20. The first starting stationary module 20, the intermediate stationary module 30, and the ending stationary module 40 are used sequentially to perform a first stationary treatment, a second stationary treatment, and a third stationary treatment on a number of batteries in the battery clamp 200 transported by the first lifting module 10. The second stationary line includes a second starting stationary module 60 and a second lifting module 90. A transport device 50 is located at the right end of the ending stationary module 40 and the second starting stationary module 60. The transport device 50 is used to transport the battery clamp 200 to the second starting stationary module 60 after the battery in the battery clamp 200 has undergone a third stationary treatment at the ending stationary module 40. The second starting point settling module 60 is used to perform a fourth settling process on several batteries in the battery clamp 200 that have been transported by the transport device 50. The second lifting module 90 is connected to the left end of the second starting point settling module 60, and is used to transport the battery clamp 200 to the second conveyor line after the battery clamp 200 has undergone the fourth settling process in the second starting point settling module 60.

[0031] Combination Figure 3 and Figure 4As shown, the battery clamp 200 has several mounting cavities, and several batteries after being filled with liquid are placed in several mounting cavities respectively. The top of the battery clamp 200 is provided with several one-way valves 201, each one-way valve 201 corresponding to a mounting cavity. The bottom of the battery clamp 200 is provided with two positioning holes 202 arranged in a front-to-back manner.

[0032] Combination Figures 5 to 12 As shown, the first lifting module 10 includes a lifting frame 11, a lifting mechanism, an active roller mechanism 13, a lifting and pulling mechanism 15, and a jacking mechanism 16. The bottom end of the lifting frame 11 is provided with support legs 111 and casters 112. The support legs 111 are used to place the lifting frame 11 on the ground to support it, and the casters 112 can move on the ground, thus facilitating the movement of the lifting frame 11 and consequently the first lifting module 10. The number of support legs 111 and casters 112 can be set according to actual conditions.

[0033] like Figures 5 to 8 As shown, the lifting mechanism includes a lifting platform 12 and a lifting drive assembly 14. The lifting platform 12 is a frame structure located within the lifting frame 11. The front and rear sides of the lifting platform 12 are slidably connected to the front and rear inner walls of the lifting frame 11, respectively. The lifting platform 12 can slide up and down relative to the lifting frame 11. Specifically, the front and rear inner walls of the lifting frame 11 are respectively provided with a front slide rail 1221 and a rear slide rail 1222. The length direction of the front slide rail 1221 and the rear slide rail 1222 is the same as the height direction of the lifting frame 11. The front and rear sides of the lifting platform 12 are respectively provided with a front slider 1223 and a rear slider 1224. The front slider 1223 slides in conjunction with the front slide rail 1221, and the rear slider 1224 slides in conjunction with the rear slide rail 1222. The number of front slide rails 1221, rear slide rails 1222, front sliders 1223, and rear sliders 1224 can be set according to actual conditions. The top of the lifting platform 12 is provided with a lifting mounting plate 121.

[0034] The lifting drive component 14 is mounted on the lifting frame 11. The lifting drive component 14 drives the lifting platform 12 to slide up and down relative to the lifting frame 11, thereby causing the lifting mounting plate 121 to move up and down. In this embodiment, as shown... Figure 6As shown, the lifting drive assembly 14 includes a lifting motor 141, a lifting reducer 142, two lifting drive shafts 143, and two lifting timing belt modules. The lifting reducer 142 is located at the top of the lifting frame 11. The lifting motor 141 is mounted on the lifting reducer 142, and the output shaft of the lifting motor 141 is connected to the input shaft of the lifting reducer 142. The two lifting drive shafts 143 are arranged in a front-to-back configuration. The adjacent ends of the two lifting drive shafts 143 are respectively connected to the two output shafts of the lifting reducer 142, and the distant ends of the two lifting drive shafts 143 are rotatably mounted at the top of the lifting frame 11 via bearing seats. The lifting timing belt modules include a lifting drive pulley 144, a lifting driven pulley 145, and a lifting timing belt 146 sleeved around the outer periphery of the lifting drive pulley 144 and the lifting driven pulley 145. The lifting drive pulleys 144 of the two lifting timing belt modules are respectively sleeved around the distant ends of the two lifting drive shafts 143. Two driven pulleys 145 of the two lifting synchronous belt modules are rotatably mounted on the front and rear sides of the lifting frame 11, respectively. The driven pulleys 145 are located below the driving pulleys 144 and close to the bottom of the lifting frame 11. Two platform connectors 124 are provided on the front and rear sides of the lifting platform 12, respectively. A platform mounting part 1241 is provided at the end of the platform connector 124 away from the lifting platform 12. The platform mounting parts 1241 of the two platform connectors 124 are located between the driving pulleys 144 and the driven pulleys 145 of the two lifting synchronous belt modules, and correspond to the lifting synchronous belts 146 of the two lifting synchronous belt modules, respectively. The platform mounting parts 1241 are sleeved on the outer periphery of one side of the corresponding lifting synchronous belt 146. The lifting motor 141 drives two lifting transmission shafts 143 to rotate via the lifting reducer 142, thereby driving the lifting drive wheel 144 of the two lifting synchronous belt modules to rotate, which in turn drives the corresponding lifting driven wheel 145 and lifting synchronous belt 146 to rotate. The rotation of the lifting synchronous belt 146 can drive the corresponding platform mounting part 1241 to move up and down, thereby driving the lifting platform 12 to slide up and down relative to the lifting frame 11 via the platform connector 124.

[0035] like Figure 5As shown, the top of the lifting frame 11 is provided with a top protective cover 1411. The lifting motor 141, lifting reducer 142, two lifting drive shafts 143, and lifting drive pulleys 144 of the two lifting synchronous belt modules are all located inside the top protective cover 1411. The top protective cover 1411 protects the lifting motor 141, lifting reducer 142, two lifting drive shafts 143, and lifting drive pulleys 144 of the two lifting synchronous belt modules. The front and rear sides of the lifting frame 11 are respectively provided with two side protective covers 1412. The lifting synchronous belts 146 and lifting driven pulleys 145 of the two lifting synchronous belt modules are located inside the two side protective covers 1412, respectively. The two side protective covers 1412 protect the lifting synchronous belts 146 and lifting driven pulleys 145 of the two lifting synchronous belt modules.

[0036] like Figure 5 , Figure 7 and Figure 9 As shown, the active roller mechanism 13 is disposed at the top of the lifting mounting plate 121. The up-and-down movement of the lifting mounting plate 121 drives the active roller mechanism 13 to move up and down. The active roller mechanism 13 includes two active roller assemblies and an active roller drive assembly. The two active roller assemblies are arranged in a front-to-back facing arrangement. Each active roller assembly includes an active roller mounting base 135 and multiple active rollers 136. The active roller mounting bases 135 of the two active roller assemblies are respectively disposed on the front and rear sides of the top of the lifting mounting plate 121 via an active roller support, and the active roller mounting bases 135 of the two active roller assemblies are arranged in a front-to-back facing arrangement. The multiple active rollers 136 are arranged sequentially from left to right at intervals within the active roller mounting bases 135. The top of the active roller mounting bases 135 is provided with multiple clearance holes 1351 corresponding to the multiple active rollers 136, and portions of the multiple active rollers 136 extend out from the corresponding clearance holes 1351. The number of active rollers 136 can be set according to actual conditions.

[0037] The active roller drive assembly is located on the left side of the top of the lifting mounting plate 121. This assembly drives the active rollers 136 of the two active roller assemblies to rotate. Specifically, the active roller drive assembly includes an active roller reduction motor 131 and an active roller drive shaft 134. The active roller reduction motor 131 is located on the left side of the top of the lifting mounting plate 121. Both ends of the active roller drive shaft 134 are rotatably mounted on the left side of the top of the lifting mounting plate 121 via bearing seats, and are located to the left of the active roller reduction motor 131. Both ends of the active roller drive shaft 134 correspond to the active roller mounting seats 135 of the two active roller assemblies. The end of the output shaft of the active roller reduction motor 131 is connected to the active roller drive shaft 134 via a first chain drive module. Of the multiple active rollers 136 in each active roller assembly, the active roller 136 closest to the active roller drive shaft 134, i.e., the first active roller 136, is connected to the active roller drive shaft 134 via a second chain drive module. Adjacent active rollers 136 are connected via a third chain drive module. The active roller reduction motor 131 drives the active roller drive shaft 134 to rotate via the first chain drive module, thereby driving the multiple active rollers 136 to rotate via the second and third chain drive modules.

[0038] The first chain drive module includes a first sprocket 132, a second sprocket 133, and a first chain (not shown in the figure) sleeved around the outer periphery of the first sprocket 132 and the second sprocket 133. The first sprocket 132 is sleeved around the outer periphery of the end of the output shaft of the drive roller reduction motor 131. The second sprocket 133 is sleeved around the outer periphery of the drive roller drive shaft 134. The drive roller reduction motor 131 drives the first sprocket 132 to rotate, thereby driving the drive roller drive shaft 134 to rotate via the first chain and the second sprocket 133. The second chain drive module includes a third sprocket 137, a fourth sprocket, and a second chain 138 sleeved around the outer periphery of the third sprocket 137 and the fourth sprocket. The third sprocket 137 is sleeved around the outer periphery of the drive roller drive shaft 134. The fourth sprocket is sleeved around the outer periphery of the axle of the first drive roller 136. The rotation of the drive roller drive shaft 134 drives the third sprocket 137 to rotate, which in turn drives the first drive roller 136 to rotate via the second chain 138 and the fourth sprocket. The third chain drive module includes a fifth sprocket, a sixth sprocket, and a third chain 139 fitted around the outer circumference of the fifth and sixth sprockets. In two adjacent drive rollers 136, the fifth sprocket is fitted around the outer circumference of the axle of one drive roller 136, and the sixth sprocket is fitted around the outer circumference of the axle of the other drive roller 136. Two adjacent drive rollers 136 rotate synchronously via a fifth sprocket, a sixth sprocket, and a third chain 139. That is, the first drive roller 136 drives the second drive roller 136 to rotate via the fifth sprocket, the sixth sprocket, and the third chain 139 of the corresponding third chain drive module. The second drive roller 136 drives the third drive roller 136 to rotate via the fifth sprocket, the sixth sprocket, and the third chain 139 of the corresponding third chain drive module. This process is repeated to achieve the rotation of multiple drive rollers 136. In practical applications, the first conveyor line is connected to the left end of the first lifting module 10 and corresponds to the two active roller assemblies. During the process of the first conveyor line conveying the battery clamp 200, when the battery clamp 200 is located on the first active roller 136 of the two active roller assemblies, the active roller reduction motor 131 drives the active roller transmission shaft 134 to rotate through the first chain transmission module. Thus, through the second chain transmission module and the third chain transmission module, the multiple active rollers 136 of the two active roller assemblies can be driven to rotate. Through the rotation of the multiple active rollers 136, the battery clamp 200 can be moved to the right.

[0039] like Figure 5 , Figure 7 , Figure 10 and Figure 11As shown, the lifting and pulling mechanism 15 is located at the top of the lifting mounting plate 121. The up-and-down movement of the lifting mounting plate 121 can drive the lifting and pulling mechanism 15 to move up and down. The lifting and pulling mechanism 15 includes a lifting and pulling drive assembly and two lifting positioning pin assemblies. The two lifting positioning pin assemblies are arranged in a front-to-back facing arrangement. The lifting and pulling drive assembly is used to drive the two lifting positioning pin assemblies to move left and right. The lifting and pulling drive assembly includes a lifting and pulling base plate 151, a first lifting and pulling cylinder 152, a lifting and pulling top plate 153, and a second lifting and pulling cylinder 154.

[0040] The lifting base plate 151 is slidably connected to the top of the lifting mounting plate 121. The lifting base plate 151 is located between the active roller mounting seats 135 of the two active roller assemblies and to the right of the active roller reduction motor 131 of the active roller drive assembly. Part of the lifting base plate 151 protrudes from the right side of the lifting frame 11. Specifically, two base plate mounting seats 1511 are respectively provided on the front and rear sides of the top of the lifting mounting plate 121. A first material pulling slider 1513 is provided at the top of the base plate mounting seat 1511. Two first material pulling slide rails 1512 are provided on the front and rear sides of the bottom of the lifting base plate 151. The length direction of the first material pulling slide rails 1512 is the same as the length direction of the lifting base plate 151. The two first material pulling slide rails 1512 are slidably engaged with the first material pulling sliders 1513 of the two base plate mounting seats 1511. The number of first material pulling sliders 1513 can be set according to actual conditions. The first lifting and pulling cylinder 152 is mounted on the top of the lifting mounting plate 121 via a cylinder seat. The first lifting and pulling cylinder 152 is located below the lifting and pulling base plate 151 and between two base plate mounting seats 1511. The end of the output shaft of the first lifting and pulling cylinder 152 is connected to the bottom end of the lifting and pulling base plate 151 via a pulling connecting block 1521. The first lifting and pulling cylinder 152 is used to drive the lifting and pulling base plate 151 to slide left and right relative to the lifting mounting plate 121. Two lifting and pulling connecting plates 1532 are respectively provided on the front and rear sides of the bottom end of the lifting and pulling top plate 153. The two lifting and pulling connecting plates 1532 are slidably connected to the top of the lifting and pulling base plate 151, and portions of the two lifting and pulling connecting plates 1532 protrude from the front and rear sides of the lifting and pulling base plate 151, respectively. Specifically, two second material-pulling slide rails 1533 are respectively provided on the front and rear sides of the top of the lifting and pulling base plate 151. The length direction of the second material-pulling slide rails 1533 is the same as the length direction of the lifting and pulling base plate 151. A second material-pulling slider 1534 is provided at the bottom of the lifting and pulling connecting plate 1532. The second material-pulling sliders 1534 of the two lifting and pulling connecting plates 1532 are slidably engaged with the two second material-pulling slide rails 1533 respectively. The second lifting and pulling cylinder 154 is set at the top of the lifting and pulling base plate 151 through a cylinder seat. The lifting and pulling top plate 153 is sleeved on the outer periphery of the end of the output shaft of the second lifting and pulling cylinder 154 through a material-pulling mounting block 1531. The second lifting and pulling cylinder 154 is used to drive the lifting and pulling top plate 153 to move left and right relative to the lifting and pulling base plate 151 through the material-pulling mounting block 1531, thereby driving the two lifting and pulling connecting plates 1532 to slide left and right relative to the lifting and pulling base plate 151 respectively.

[0041] The lifting base plate 151 is located between two lifting positioning pin assemblies. Each lifting positioning pin assembly includes a lifting positioning pin 157 and a lifting positioning cylinder 156. The lifting positioning cylinder 156 is positioned at the top of a lifting cylinder seat 155, and the lifting cylinder seats 155 of the two lifting positioning pin assemblies are respectively connected to the right ends of the two lifting material pulling connecting plates 1532. The lifting positioning cylinder 156 and the lifting positioning pin 157 are arranged side-by-side. The output shaft of the lifting positioning cylinder 156 and the lifting positioning pin 157 respectively pass through two through holes in the lifting cylinder seat 155. The bottom end of the lifting positioning pin 157 is connected to the end of the output shaft of the lifting positioning cylinder 156 via a positioning pin connecting block 158. The top end of the lifting positioning pin 157 is provided with a pin shaft 1571, and the pin shafts 1571 of the two lifting positioning pin assemblies are respectively used to cooperate with the two positioning holes 202 of the battery clamp 200. The lifting positioning cylinder 156 drives the lifting positioning pin 157 to move up and down via the positioning pin connecting block 158, thereby driving the pin shaft 1571 to move up and down. Through the up and down movement of the pin shafts 1571 of the two lifting positioning pin assemblies, they can engage or disengage with the two positioning holes 202 of the battery clamp 200. When the lifting pulling base plate 151 slides left and right, it drives the lifting pulling top plate 153, the second lifting pulling cylinder 154, and the two lifting pulling connecting plates 1532 to move left and right, thereby driving the two lifting positioning pin assemblies to move left and right. When the two lifting pulling connecting plates 1532 slide left and right, they can each drive the two lifting positioning pin assemblies to move left and right respectively.

[0042] like Figure 5 , Figure 7 , Figure 8 and Figure 12 As shown, the lifting mechanism 16 is mounted on the lifting mounting plate 121. The up-and-down movement of the lifting mounting plate 121 drives the lifting mechanism 16 to move up and down. The lifting mechanism 16 includes a lifting drive assembly and two passive roller assemblies. The two passive roller assemblies are arranged in a front-to-back facing arrangement. The lifting drive assembly is used to drive the two passive roller assemblies to move up and down. The lifting drive assembly includes a lifting base plate 164, a lifting top plate 165, and a lifting cylinder 166.

[0043] The lifting top plate 165 and the lifting bottom plate 164 are located sequentially below the lifting platform 12. A lifting guide rod 167 is provided at the top of the lifting bottom plate 164. The top of the lifting guide rod 167 passes through the through hole of the lifting top plate 164 and the through hole of the lifting platform 12, and connects to the bottom end of the lifting mounting plate 121. A lifting linear bearing 168 is provided in the through hole of the lifting top plate 165. The lifting linear bearing 168 is sleeved on the outer periphery of the lifting guide rod 167 to provide support for the vertical movement of the lifting guide rod 167. In this embodiment, there are four lifting guide rods 167, which are respectively located at the four corners of the top of the lifting bottom plate 164. The lifting top plate 164 also has two through holes and two lifting linear bearings 168. The lifting cylinder 166 is located at the top of the lifting base plate 164. The end of the output shaft of the lifting cylinder 166 is connected to the bottom end of the lifting top plate 165. The lifting cylinder 166 is used to drive the lifting top plate 165 to move up and down.

[0044] The passive roller assembly includes a passive roller mounting base 163, a passive roller mounting frame 161, and multiple passive rollers 162. The passive roller mounting frame 161 is located at the top of the passive roller mounting base 163, and the bottom end of the passive roller mounting base 163 passes through the through hole 1211 of the lifting mounting plate 121 and the through hole of the lifting platform 12, connecting to the top of the lifting top plate 165. The passive roller mounting frames 161 of the two passive roller assemblies are located between the active roller mounting bases 135 of the two active roller assemblies, and the lifting and pulling mechanism 15 is located between the passive roller mounting frames 161 of the two passive roller assemblies. Multiple passive rollers 162 are arranged sequentially from left to right within the passive roller mounting frame 161, with portions of each passive roller 162 protruding from the top of the passive roller mounting frame 161. The multiple passive rollers 162 are used to support the battery clamp 200. When the lifting plate 165 moves up and down, it can drive the passive roller mounting seats 163 of the two passive roller assemblies to move up and down, thereby driving the corresponding passive roller mounting brackets 161 and multiple passive rollers 162 to move up and down. In practical applications, when the battery clamp 200 is transported to the right to the predetermined position by the active roller mechanism 13, the lifting cylinder 166 drives the multiple passive rollers 162 of the two passive roller assemblies to move upward, thereby supporting the battery clamp 200. Then, the lifting positioning cylinders 156 of the two lifting positioning pin assemblies drive the corresponding pin shafts 1571 to move upward, so that the pin shafts 1571 of the two lifting positioning pin assemblies can cooperate with the two positioning holes 202 of the battery clamp 200.

[0045] The structure of the second lifting module 90 is the same as that of the first lifting module 10, and will not be described again here. In practical applications, the second conveyor line is connected to the left end of the second lifting module 90, and the second conveyor line corresponds to the two active roller assemblies of the second lifting module 90.

[0046] Combination Figures 13 to 19 As shown, the first starting point stationary module 20 includes a stationary frame 21 and two stationary units. The stationary frame 21 is connected to the lifting frame 11. The bottom of the stationary frame 21 is provided with legs 211 and casters 212. The legs 211 are used to support the stationary frame 21 on the ground, and the casters 212 can move on the ground, thus facilitating the movement of the stationary frame 21 and consequently the first starting point stationary module 20. The number of legs 211 and casters 212 can be set according to actual conditions. The two stationary units are an upper stationary unit and a lower stationary unit.

The stationary linear bearing 22251 is sleeved on the outer periphery of the stationary guide rod 2225 to provide support for the vertical movement of the stationary guide rod 2225. In this embodiment, there are two stationary guide rods 2225, respectively located on the front and rear sides of the top of the stationary base plate 2221. The stationary linear bearing 22251 and the through hole in the stationary top plate 2222 are also two in number. The top of the stationary mounting plate 2223 is provided with two stationary positioning pins 2224, which are arranged in a front-to-back manner and are used to cooperate with the two positioning holes 202 of the battery clamp 200.

[0052] In the four stationary positioning pin assemblies 222, the stationary tops 2222 of two adjacent stationary positioning pin assemblies 222 are connected by two first stationary connectors 2231, which are arranged in a front-to-back orientation. In the four stationary positioning pin assemblies 222, along the direction from left to right, the bottom end of the stationary top plate 2222 of the second stationary positioning pin assembly 222 is provided with a stationary connecting bracket 2215, and a stationary connecting seat 2214 is sleeved on the outer periphery of the stationary nut 2213, which is located at the bottom end of the stationary connecting bracket 2215. The left and right movement of the stationary nut 2213 can drive the stationary connecting seat 2214 to move left and right. Thus, the stationary connecting seat 2215 can drive the stationary top plate 2222 of the second stationary positioning pin assembly 222 to slide left and right relative to the stationary frame 21. The left and right sliding of the stationary top plate 2222 of the second stationary positioning pin assembly 222 can drive the stationary top plates 2222 of the other three stationary positioning pin assemblies 222 to slide left and right relative to the stationary frame 21. The left and right sliding of the stationary top plate 2222 can drive the stationary bottom plate 2221, the stationary mounting plate 2223, the stationary connecting plate 2226, the spherical bearing 2227, and the stationary mounting block 2228 to move left and right. In this way, the stationary material pulling drive assembly can drive the four stationary positioning pin assemblies 222 to move left and right.

[0053] The stationary cylinder 224 is disposed between the third stationary positioning pin assembly 222 and the fourth stationary positioning pin assembly 222. The top ends of the two first stationary connecting members 2231 between the third and fourth stationary positioning pin assemblies 222 are provided with two second stationary connecting members 22321 arranged opposite each other. The stationary cylinder 224 is disposed at the bottom ends of the two second stationary connecting members 22321.

The stationary cylinder 2224 is used to drive the stationary connecting plate 2226 of the third stationary positioning pin assembly 222 to slide left and right relative to the stationary top plate 2222. The stationary connecting plates 2226 of two adjacent stationary positioning pin assemblies 222 are connected by a stationary connecting rod 2241. Under the drive of the stationary connecting rod 2241, the left and right sliding of the stationary connecting plate 2226 of the third stationary positioning pin assembly 222 can drive the stationary connecting plates 2226 of the other stationary positioning pin assemblies 222 to slide left and right relative to the corresponding stationary top plate 2222. During the process of the stationary connecting plate 2226 sliding left and right relative to the stationary top plate 2222, under the restriction of the stationary top plate 2222, the stationary connecting plate 2226 can drive the joint bearing 2227 to rotate left and right. Under the action of the stationary guide rod 2225 and the stationary mounting block 2228, the rotation of the joint bearing 2226 can drive the stationary mounting plate 2223 to move up and down, which in turn can drive the two stationary positioning pins 2224 to move up and down. Through the up and down movement of the two stationary positioning pins 2224, they can be engaged or separated from the two positioning holes 202 of the battery clamp 200.

[0055] like Figure 18 and Figure 19As shown, the breathing mechanism 23 includes a breathing mounting plate 231, a breathing drive assembly, and a breathing assembly 235. In this embodiment, there are four breathing assemblies 235, which are arranged alternately from left to right. Each breathing assembly 235 corresponds to a stationary positioning pin assembly 222. It can be understood that the number of breathing assemblies 235 can be set according to the actual situation.

[0056] The breathing mounting plate 231 of the upper static unit is set on the top inner wall of the static frame 21, and the breathing mounting plate 231 of the lower static unit is set at the bottom of the upper mounting frame 213.

[0057] The breathing drive assembly is located at the bottom end of the breathing mounting plate 231. Specifically, the breathing drive assembly includes a breathing motor 2321, a breathing lead screw 2322, and a breathing nut 2323. The breathing motor 2321 is mounted at the bottom end of the breathing mounting plate 231 via a motor mount. One end of the breathing lead screw 2322 is connected to the end of the output shaft of the breathing motor 2321, and the other end of the breathing lead screw 2322 is rotatably mounted at the bottom end of the breathing mounting plate 231 via a bearing seat. The breathing nut 2323 is threadedly engaged with the breathing lead screw 2322. The breathing motor 2321 drives the breathing lead screw 2322 to rotate, thereby causing the breathing nut 2323 to move left and right.

[0058] The breathing assembly 235 includes a nozzle plate 2351. A plurality of positioning posts 2352 are evenly distributed at the bottom end of the nozzle plate 2351. The number of positioning posts 2352 can be set according to actual conditions. Each positioning post 2352 is used to abut against the top of a plurality of one-way valves 201 of the battery clamp 200. The interiors of each positioning post 2352 are used to communicate with the inlets at the top of the one-way valves 201. The interiors of each positioning post 2352 are also used to communicate with the air passages inside the nozzle plate 2351. The nozzle plate 2351 is provided with a connector that communicates with the air passages. The connector is connected to a solenoid valve 2353. The solenoid valve 2353 is mounted on the top of the breathing mounting plate 231 via a valve seat 2354. The solenoid valve 2353 is used to connect to a vacuum device. The position and number of connectors and the number of solenoid valves 2353 can be set according to actual conditions. The top of the nozzle plate 2351 is provided with a breathing guide rod 2355. The top of the breathing guide rod 2355 passes through the through hole of the breathing mounting plate 231 and is located above the breathing mounting plate 231. A breathing linear bearing 2356 is provided in the through hole of the breathing mounting plate 231. The breathing linear bearing 2356 is sleeved on the outer periphery of the breathing guide rod 2355 to provide support for the up and down movement of the breathing guide rod 2355. In this embodiment, there are two breathing guide rods 2355, which are respectively arranged on the front and rear sides of the top of the nozzle plate 2351. There are also two through holes in the breathing mounting plate 231 and two breathing linear bearings 2356. The nozzle plates 2351 of the four breathing components 235 are all located at the bottom end of the breathing connecting plate 234. A breathing moving plate is slidably connected to the bottom end of the breathing mounting plate 231. The breathing moving plate is located above the breathing connecting plate 234 and is connected to the breathing nut 2323. The left and right movement of the breathing nut 2323 can drive the breathing moving plate to slide left and right relative to the breathing mounting plate 231, thereby enabling the breathing drive component to drive the breathing moving plate to slide left and right relative to the breathing mounting plate 231. The bottom end of the breathing moving plate is provided with a downward-extending breathing connecting block 2334. The breathing connecting block 2334 is provided with an inclined groove 23341, which is inclined downward. The breathing connecting plate 234 is provided with a cam follower 2341, which cooperates with the inclined groove 23341.The left and right sliding of the breathing moving plate can drive the breathing connecting block 2334 to move left and right. Under the action of the cam follower 2341 and the inclined groove 23341, the left and right movement of the breathing connecting block 2334 can drive the breathing connecting plate 234 to move up and down, thereby driving the nozzle plates 2351 of the four breathing components 235 to move up and down, which in turn can drive the corresponding positioning pins 2352 to move up and down. Through the up and down movement of the positioning pins 2352, they can abut or separate from the tops of the one-way valves 202. When the tops of valves 202 abut against each other, the interiors of several positioning pins 2352 can be connected to the inlet of the top of the corresponding one-way valve 202, and the one-way valve 202 is opened under the pressure of the corresponding positioning pins 2352. At this time, through the vacuum equipment, the several mounting cavities of the battery clamp 200 can be vacuumed, vacuumed, or air introduced through the solenoid valve 2353, the connector, the air passage of the air nozzle plate 2351, the interiors of several positioning pins 2352, and several one-way valves 202, thereby realizing the breathing action of several batteries and allowing the electrolyte to completely wet the interior of the battery cell.

[0059] In this embodiment, the breathing movable plate includes three sub-moving plates 233 arranged sequentially from left to right at intervals. The sub-moving plates 233 are slidably connected to the bottom end of the breathing mounting plate 231.

Specifically, the top of each sub-moving plate 233 is provided with a breathing slider 2333, and the bottom of the breathing mounting plate 231 is provided with a breathing slide rail 2332.

The breathing sliders 2333 of the three sub-moving plates 233 slide in cooperation with the breathing slide rails 2332. The number of breathing sliders 2333 and breathing slide rails 2332 can be set according to actual conditions. Among the three sub-moving plates 233, the middle sub-moving plate 233 is connected to a breathing nut 2323 via a nut mounting seat. The left and right movement of the breathing nut 2323 can drive the middle sub-moving plate 233 to move left and right, thereby driving the other two sub-moving plates 233 to move left and right. Each sub-moving plate 233 is provided with the above-mentioned breathing connection block 2334 at its bottom end, that is, there are three breathing connection blocks 2334, and correspondingly, there are also three cam followers 2341 of the breathing connection plate 234.

[0060] The structures of the endpoint stationary module 40 and the second starting point stationary module 60 are the same as those of the first starting point stationary module 20. The structure of the intermediate stationary module 30 is also the same as that of the first starting point stationary module 20, the only difference being that the length of the intermediate stationary module 30 is less than that of the first starting point stationary module 20. The structures of the intermediate stationary module 30, the endpoint stationary module 40, and the second starting point stationary module 60 will not be described in detail here.

[0062] The transport base frame 51 is set at the right end of the stationary frame 21 of the endpoint stationary module 40 and the stationary frame 21 of the second starting point stationary module 60. For example... Figure 20 As shown, the bottom end of the transport base frame 51 is provided with support legs 511 and casters 512. The support legs 511 are used to place on the ground to support the transport base frame 51, and the casters 512 can move on the ground, thereby facilitating the movement of the transport base frame 51 and, consequently, the movement of the transport device 50. The number of support legs 511 and casters 512 can be set according to actual needs. A transport drive unit is disposed on the transport base frame 51 and the transport unit 52. The transport unit 52 is slidably connected to the top of the transport base frame 51, and the transport drive unit is used to drive the transport unit 52 to slide back and forth relative to the transport base frame 51.

[0063] Specifically, such as Figure 20 , Figures 22 to 26 As shown, the handling unit 52 includes a handling frame 521, a handling up-and-down moving mechanism, a handling roller mechanism, and a handling pulling mechanism 526.

[0064] The transport frame 521 is slidably connected to the top of the transport base frame 51. Specifically, as shown...

The first gear 533 is sleeved on the outer circumference of the end of the output shaft of the transport reducer, and the second gear 532 is rotatably mounted on the bottom end of the reducer base 5312 and meshes with the first gear 533. A gear protective cover is provided on the rear side of the transport frame 521, and both the first gear 533 and the second gear 532 are located within the gear protective cover, which protects both the first gear 533 and the second gear 532. A rack 516 is positioned at the top of the transport base frame 51, with its length direction parallel to the width direction of the transport base frame 51. A first gear 533 meshes with the rack 516. A rack protective cover 5161 is provided at the top of the transport base frame 51, with the rack 516 located inside the rack protective cover 5161. A transport motor drives the first gear 533 to rotate via a transport reducer. Under the action of the meshing of the first gear 533 and the rack 516, the first gear 533 can move back and forth along the rack 516. This, in turn, via the transport reducer and reducer base 5312, drives the transport frame 521 to slide back and forth relative to the transport base frame 51. The rotation of the first gear 533 drives the second gear 532 to rotate, and the second gear 532 provides rotational support for the first gear 533.

The front slider 5223 is slidably engaged with the front slide rail 5222, and the rear slider 5225 is slidably engaged with the rear slide rail 5224. The number of front slide rail 5222, rear slide rail 5224, front slider 5223, and rear slider 5225 can be set according to actual needs. The top of the transport platform 522 is equipped with a transport mounting plate 5221.

[0067] A vertical drive assembly is mounted on the transport frame 521. This assembly drives the transport platform 522 to slide vertically relative to the transport frame 521, thereby moving the transport mounting plate 5221 vertically. In this embodiment, as shown... Figure 23As shown, the conveying up-and-down drive assembly includes an up-and-down motor 5251, an up-and-down reducer 5252, two up-and-down drive shafts 5253, and two up-and-down synchronous belt modules.

The platform mounting parts 527 are sleeved on the outer periphery of one side of the corresponding upper and lower synchronous belts 5256. The upper and lower motors 5251 are used to drive the two upper and lower transmission shafts 5253 to rotate through the upper and lower reducers 5252, thereby driving the upper and lower drive wheels 5254 of the two upper and lower synchronous belt modules to rotate, which in turn drives the corresponding upper and lower driven wheels 5255 and the upper and lower synchronous belts 5256 to rotate. The rotation of the upper and lower synchronous belts 5256 can drive the corresponding platform mounting parts 5227 to move up and down, thereby driving the transport platform 522 to slide up and down relative to the transport frame 521 through the platform connector 5226.

The multiple transport rollers 524 are arranged sequentially and spaced apart from left to right on the top of the transport roller mounting bases 523.

[0070] The material handling and pulling mechanism 526 is located at the top of the material handling mounting plate 5221. The up-and-down movement of the material handling mounting plate 5221 drives the material handling and pulling mechanism 526 to move up and down. The material handling and pulling mechanism 526 is located between the material handling roller mounting seats 523 of the two material handling roller assemblies. The material handling and pulling mechanism 526 includes a material handling and pulling drive assembly and two material handling positioning pin assemblies. The two material handling positioning assemblies are arranged in a front-to-back facing manner. The material handling and pulling drive assembly is used to drive the two material handling positioning pin assemblies to move left and right. The material handling and pulling drive assembly includes a material handling and pulling base plate 5261, a first material handling and pulling cylinder 5262, a material handling and pulling top plate 5263, and a second material handling and pulling cylinder 5264.

[0071] like Figures 24 to 26As shown, the material handling base plate 5261 is slidably connected to the top of the material handling mounting plate 5221 and located between the material handling roller mounting seats 523 of the two material handling roller assemblies. Part of the material handling base plate 5261 protrudes from the left side of the material handling frame 521. Specifically, two base plate mounting seats 52613 are respectively provided on the front and rear sides of the top of the top of the material handling mounting plate 5221. A first material handling slider 52612 is provided at the top of the base plate mounting seat 52613. Two first material handling slide rails 52611 are provided on the front and rear sides of the bottom of the material handling base plate 5261. The length direction of the first material handling slide rails 52611 is the same as the length direction of the material handling base plate 5261. The two first material handling slide rails 52611 are slidably engaged with the first material handling sliders 52612 of the two base plate mounting seats 52613. The number of first material handling sliders 52612 can be set according to actual conditions. A first material handling cylinder 5262 is mounted on the top of the material handling mounting plate 5221 via a cylinder seat. The first material handling cylinder 5262 is located below the material handling base plate 5261 and between the two base plate mounting seats 52613. The end of the output shaft of the first material handling cylinder 5262 is connected to the bottom end of the material handling base plate 5261 via a material handling connecting block 52621. The first material handling cylinder 5262 is used to drive the material handling base plate 5261 to slide left and right relative to the material handling mounting plate 5221 via the material handling connecting block 52621. Two material handling connecting plates 5265 are respectively provided on the front and rear sides of the bottom end of the material handling top plate 5263, and the two material handling connecting plates 5265 are slidably connected to the top of the material handling base plate 5261. Specifically, two second material-pulling slide rails 52651 are respectively provided on the front and rear sides of the top of the material-pulling base plate 5261. The length direction of the second material-pulling slide rails 52651 is the same as the length direction of the material-pulling base plate 5261. A second material-pulling slider 52652 is provided at the bottom of the material-pulling connecting plate 5265. The second material-pulling sliders 52652 of the two material-pulling connecting plates 5265 are slidably engaged with the two second material-pulling slide rails 52651 respectively. The second material-pulling cylinder 5264 is set at the top of the material-pulling base plate 5261 through a cylinder seat. The material-pulling top plate 5263 is sleeved on the outer periphery of the end of the output shaft of the second material-pulling cylinder 5264 through a material-pulling mounting block 52631. The second material handling cylinder 5264 is used to drive the material handling top plate 5263 to move left and right relative to the material handling bottom plate 5261 via the material handling mounting block 52631, thereby driving the two material handling connecting plates 5265 to slide left and right relative to the material handling bottom plate 5261 respectively.

[0072] The material handling base plate 5261 is located between two material handling positioning pin assemblies. Each material handling positioning pin assembly includes a material handling positioning pin 5268 and a material handling positioning cylinder 5267. The material handling positioning cylinder 5267 is located at the top of the material handling cylinder seat 5266, and the material handling positioning pin 5268 and the material handling positioning cylinder 5267 are arranged side-by-side. The material handling cylinder seats 5266 of the two material handling positioning pin assemblies are respectively connected to the left ends of the two material handling connecting plates 5265. The output shaft of the material handling positioning cylinder 5267 and the material handling positioning pin 5268 are respectively arranged through two through holes in the material handling cylinder seat 5266. The bottom end of the material handling positioning pin 5268 is connected to the end of the output shaft of the material handling positioning cylinder 5267 via a positioning pin connecting block 5269. The top end of the material handling positioning pin 5268 is provided with a material handling pin shaft 52681. The material handling pin shafts 52681 of the two material handling positioning pin assemblies are respectively used to cooperate with the two positioning holes 202 of the battery clamp 200. The transport positioning cylinder 5267 drives the transport positioning pin 5268 to move up and down, thereby driving the transport pin shaft 52681 to move up and down. Through the up and down movement of the transport pin shaft 52681 of the two transport positioning pin assemblies, they can engage or disengage with the two positioning holes 202 of the battery clamp 200. When the transport pulling base plate 5261 slides left and right, it can drive the transport pulling top plate 5263, the second transport pulling cylinder 5264, and the two transport pulling connecting plates 5265 to move left and right, thereby driving the two transport positioning pin assemblies to move left and right. When the two transport pulling connecting plates 5265 slide left and right, they can each drive the two transport positioning pin assemblies to move left and right respectively.

[0073] With the above structure, in practical application, in the initial state, the lifting platform 12 of the first lifting module 10 corresponds to the lower stationary unit of the first starting stationary module 20. The transport unit 52 of the transport device 50 is located to the right of the ending stationary module 40. The two transport roller assemblies of the transport unit 52 correspond to the two unpowered roller mechanisms of the lower stationary unit of the ending stationary module 40. The lifting platform 12 of the second lifting module 90 corresponds to the lower stationary unit of the second starting stationary module 60, and the two passive roller assemblies of the second lifting module 90 correspond to the two unpowered roller mechanisms of the lower stationary unit of the second starting stationary module 60. The battery clamp 200 is transported via the first conveyor line.

[0074] The first lifting module 10 first transports the first four battery clamps 200 conveyed by the first conveyor line to the lower stationary unit of the first starting stationary module 20 in sequence. For example, the active roller drive assembly first drives the multiple active rollers 136 of the two active roller assemblies to rotate. When the first battery clamp 200 is located on the first active roller 136 of the two active roller assemblies, the rotation of the multiple active rollers 136 of the two active roller assemblies can drive the first battery clamp 200 to move to the right to a predetermined position. Then, the lifting cylinder 166 drives the two passive roller assemblies to move upward to a predetermined position, thereby driving the first battery clamp 200 to move upward to the predetermined position. At this time, the first battery clamp 200 is located on the two passive roller assemblies and separated from the multiple active rollers 136 of the two active roller assemblies. Thus, the multiple passive rollers 162 of the two passive roller assemblies can support the first battery clamp 200. At this time, the pins 1571 of the two lifting positioning pin assemblies are located below the two positioning holes 202 of the first battery clamp 200. Then, the lifting positioning cylinders 156 of the two lifting positioning pin assemblies drive the corresponding pin shafts 1571 upward, so that the pin shafts 1571 of the two lifting positioning pin assemblies respectively engage with the two positioning holes 202 of the first battery clamp 200. Then, the first lifting pulling cylinder 152 drives the lifting pulling base plate 151 to move to the right, so that part of the lifting pulling base plate 151 extends into the lower mounting position 2141 of the first starting stationary module 20. Then, the second lifting pulling cylinder 154 drives the two lifting positioning pin assemblies to move to the right, thereby driving the first battery clamp 200 to move to the right to the predetermined position. At this time, the first battery clamp 200 is located on the two passive roller assemblies and the two unpowered roller mechanisms of the lower stationary unit of the first starting stationary module 20. Then, the lifting positioning cylinders 156 of the two lifting positioning pin assemblies drive the corresponding pin shafts 1571 downward to the initial position, so that the pin shafts 1571 of the two lifting positioning pin assemblies separate from the two positioning holes 202 of the first battery clamp 200. Then, the second lifting and pulling cylinder 154 drives the two lifting positioning pin assemblies to move to the left to the initial position, while the first lifting and pulling cylinder 152 drives the lifting and pulling base plate 151 to move to the left to the initial position. After the stationary pulling mechanism of the lower stationary unit of the first starting stationary module 20 moves the first battery clamp 200 to below the first breathing assembly 235 of the lower stationary unit of the first starting stationary module 20, the lifting cylinder 166 drives the two passive roller assemblies to move downward to the initial position.

[0075] When the second battery clamp 200 is positioned on the first active roller 136 of the two active roller assemblies, the rotation of the multiple active rollers 136 of the two active roller assemblies can move the second battery clamp 200 to the right to a predetermined position. Then, following the above steps, the second battery clamp 200 can be moved to the right to a predetermined position. At this time, the second battery clamp 200 is positioned on the two passive roller assemblies and the two unpowered roller mechanisms of the lower stationary unit of the first starting stationary module 20. In this manner, the third battery clamp 200 and the fourth battery clamp 200 can be moved to the right to predetermined positions in sequence, so that the third battery clamp 200 and the fourth battery clamp 200 are positioned on the two passive roller assemblies and the two unpowered roller mechanisms of the lower stationary unit of the first starting stationary module 20. In this way, the first lifting module 10 can realize the sequential transport of the four battery clamps 200 to the lower stationary unit of the first starting stationary module 20.

[0076] Then, the first lifting module 10 sequentially transports the last four battery clamps 200 conveyed by the first conveyor line to the upper stationary unit of the first starting stationary module 20. This step is the same as the previous step, except that after the two lifting positioning pins 1571 are engaged with the two positioning holes 202 of the first battery clamp 200, the lifting drive assembly 14 drives the lifting platform 12 to move upward, so that the two active roller assemblies correspond to the two unpowered roller mechanisms of the upper stationary unit. Then, the previous steps are repeated. In this way, the first lifting module 10 can sequentially transport the last four battery clamps 200 to the upper stationary unit of the first starting stationary module 20.

[0077] The first stationary module 20 performs the first stationary treatment on several batteries within the battery clamp 200. The lower stationary unit then operates as follows: For example, when the first battery clamp 200 is positioned on two passive roller assemblies and two unpowered roller mechanisms, the stationary pulling drive assembly first drives four stationary positioning pin assemblies 222 to move to the left to a predetermined position. At this time, the two stationary positioning pins 2224 of the first stationary positioning pin assembly 222 are located below the two positioning holes 202 of the first battery clamp 200. Then, the stationary cylinder 224 drives the two stationary positioning pins 2224 of the four stationary positioning pin assemblies 222 to move upward, so that the two stationary positioning pins 2224 of the first stationary positioning pin assembly 222 engage with the two positioning holes 202 of the first battery clamp 200. Then, the stationary pulling drive assembly drives the four stationary positioning pin assemblies 222 to move to the right, thereby moving the first battery clamp 200 to the right to a predetermined position. At this time, the first battery clamp 200 is located below the first breathing assembly 235. Then, the stationary cylinder 224 drives the two stationary positioning pins 2224 of the four stationary positioning pin assemblies 222 to move downward, so that the two stationary positioning pins 2224 of the first stationary positioning pin assembly 222 separate from the two positioning holes 202 of the first battery clamp 200.

[0078] When the second battery clamp 200 is positioned on the two passive roller assemblies and the two unpowered roller mechanisms, the four stationary positioning pin assemblies 222 are first moved to the left to a predetermined position by the stationary pulling drive assembly. At this time, the two stationary positioning pins 2224 of the first stationary positioning pin assembly 222 are located below the two positioning holes 202 of the second battery clamp 200, and the two stationary positioning pins 2224 of the second stationary positioning pin assembly 222 are located below the two positioning holes 202 of the first battery clamp 200. Then, the two stationary positioning pins 2224 of the four stationary positioning pin assemblies 222 are moved upward by the stationary cylinder 224, so that the two stationary positioning pins 2224 of the first stationary positioning pin assembly 222 engage with the two positioning holes 202 of the second battery clamp 200, and the two stationary positioning pins 2224 of the second stationary positioning pin assembly 222 engage with the two positioning holes 202 of the first battery clamp 200. Then, the stationary feeding drive assembly drives the four stationary positioning pin assemblies 222 to move to the right, thereby moving the first battery clamp 200 and the second battery clamp 200 to the right until the second battery clamp 200 is below the first breathing assembly 235 and the first battery clamp 200 is below the second breathing assembly 235. Then, the stationary cylinder 224 drives the two stationary positioning pins 2224 of the four stationary positioning pin assemblies 222 to move downward, so that the two stationary positioning pins 224 of the first stationary positioning pin assembly 222 separate from the two positioning holes 202 of the second battery clamp 200, and the two stationary positioning pins 224 of the second stationary positioning pin assembly 222 separate from the two positioning holes 202 of the first battery clamp 200.

[0079] When the third battery clamp 200 is positioned on the two passive roller assemblies and the two unpowered roller mechanisms, the four stationary positioning pin assemblies 222 are first driven to move to the left to a predetermined position by the stationary pulling drive assembly. At this time, the two stationary positioning pins 2224 of the first stationary positioning pin assembly 222 are located below the two positioning holes 202 of the third battery clamp 200, the two stationary positioning pins 2224 of the second stationary positioning pin assembly 222 are located below the two positioning holes 202 of the second battery clamp 200, and the two stationary positioning pins 2224 of the third stationary positioning pin assembly 222 are located below the two positioning holes 202 of the first battery clamp 200. Then, the stationary cylinder 224 drives two stationary positioning pins 2224 of the four stationary positioning pin assemblies 222 to move upward, so that the two stationary positioning pins 2224 of the first stationary positioning pin assembly 222 engage with the two positioning holes 202 of the third battery clamp 200, the two stationary positioning pins 2224 of the second stationary positioning pin assembly 222 engage with the two positioning holes 202 of the second battery clamp 200, and the two stationary positioning pins 2224 of the third stationary positioning pin assembly 222 engage with the two positioning holes 202 of the first battery clamp 200. Then, the stationary pulling drive assembly drives the four stationary positioning pin assemblies 222 to move to the right, thereby driving the first battery clamp 200, the second battery clamp 200, and the third battery clamp 200 to move to the right until the third battery clamp 200 is below the first breathing assembly 235, the second battery clamp 200 is below the second breathing assembly 235, and the first battery clamp 200 is below the third breathing assembly 235. Then, the stationary cylinder 224 drives the two stationary positioning pins 2224 of the four stationary positioning pin assemblies 222 to move downward, so that the two stationary positioning pins 2224 of the first stationary positioning pin assembly 222 separate from the two positioning holes 202 of the third battery clamp 200, the two stationary positioning pins 2224 of the second stationary positioning pin assembly 222 separate from the two positioning holes 202 of the second battery clamp 200, and the two stationary positioning pins 2224 of the third stationary positioning pin assembly 222 separate from the two positioning holes 202 of the first battery clamp 200.

[0080] When the fourth battery clamp 200 is positioned on the two passive roller assemblies and the two unpowered roller mechanisms, the four stationary positioning pin assemblies 222 are first driven to move to the left to a predetermined position by the stationary pulling drive assembly. At this time, the two stationary positioning pins 2224 of the first stationary positioning pin assembly 222 are located below the two positioning holes 202 of the fourth battery clamp 200, the two stationary positioning pins 2224 of the second stationary positioning pin assembly 222 are located below the two positioning holes 202 of the third battery clamp 200, the two stationary positioning pins 2224 of the third stationary positioning pin assembly 222 are located below the two positioning holes 202 of the second battery clamp 200, and the two stationary positioning pins 2224 of the fourth stationary positioning pin assembly 222 are located below the two positioning holes 202 of the first battery clamp 200. Then, the stationary cylinder 224 drives two stationary positioning pins 2224 of the four stationary positioning pin assemblies 222 to move upward, so that the two stationary positioning pins 2224 of the first stationary positioning pin assembly 222 engage with the two positioning holes 202 of the fourth battery clamp 200, the two stationary positioning pins 2224 of the second stationary positioning pin assembly 222 engage with the two positioning holes 202 of the third battery clamp 200, the two stationary positioning pins 2224 of the third stationary positioning pin assembly 222 engage with the two positioning holes 202 of the second battery clamp 200, and the two stationary positioning pins 2224 of the fourth stationary positioning pin assembly 222 engage with the two positioning holes 202 of the first battery clamp 200. Then, the stationary pulling drive assembly drives the four stationary positioning pin assemblies 222 to move to the right, thereby driving the four battery clamps 200 to move to the right until the fourth battery clamp 200 is located below the four breathing assemblies 235. Then, the stationary cylinder 224 drives the two stationary positioning pins 2224 of the four stationary positioning pin assemblies 222 to move downward, so that the two stationary positioning pins 2224 of the four stationary positioning pin assemblies 222 separate from the two positioning holes 202 of the four battery clamps 200 respectively.

[0081] Then, the breathing drive assembly drives the positioning pins 2352 of the four breathing components 235 to move downward, so that the positioning pins 2352 of the four breathing components 235 respectively abut against the top of the one-way valves 201 of the four battery clamps 200, so that the one-way valves 201 open. At this time, the interior of the positioning pins 2352 is connected to the inlet of the top of the corresponding one-way valve 201. Then, a vacuum device is used to evacuate the mounting cavities of the corresponding battery clamps 200 through several positioning columns 2352, creating a negative pressure state within the mounting cavities. After a predetermined time, the vacuum device is used to break the vacuum in the mounting cavities of the corresponding battery clamps 200 through several positioning columns 2352, changing the negative pressure state to a normal pressure state. After a predetermined time, air is introduced into the mounting cavities of the corresponding battery clamps 200 through several positioning columns 2352, changing the normal pressure state to a positive pressure state. After a predetermined time, the vacuum evacuation, vacuum breaking, and air introduction operations are repeated in the mounting cavities. This cycle is repeated to achieve the negative pressure, normal pressure, and positive pressure breathing action of the batteries in the four battery clamps 200, allowing the electrolyte to completely soak into the interior of the battery cells. This completes the first settling treatment of the batteries in the battery clamps 200.

[0082] After the batteries in the four battery clamps 200 have finished breathing, the breathing drive assembly drives the positioning pins 2352 of the four breathing components 235 to move upward, causing the positioning pins 2352 of the four breathing components 235 to separate from the one-way valves 201 of the four battery clamps 200. Then, the stationary cylinder 224 drives the two stationary positioning pins 2224 of the four stationary positioning pin assemblies 222 to move upward, so that the two stationary positioning pins 2224 of the four stationary positioning pin assemblies 222 respectively engage with the two positioning holes 202 of the four battery clamps 200. Then, the stationary material pulling drive assembly drives the four stationary positioning pin assemblies 222 to move to the right to a predetermined position, thereby driving the four battery clamps 200 to move to the right to a predetermined position, so that the fourth battery clamp 200 is located on the two unpowered roller mechanisms of the lower stationary unit of the first starting stationary module 20 and the two unpowered roller mechanisms of the lower stationary unit of the intermediate stationary module 30. Then, the stationary cylinder 224 drives the two stationary positioning pins 2224 of the four stationary positioning pin assemblies 222 to move downward, thereby separating the two stationary positioning pins 2224 of the four stationary positioning pin assemblies 222 from the two positioning holes 202 of the four battery clamps 200 respectively. After the fourth battery clamp 200 is moved to the right by the stationary pulling mechanism of the lower stationary unit of the intermediate stationary module 30 and placed below the first breathing component 235 of the lower stationary unit of the intermediate stationary module 30, the four stationary positioning pin assemblies 222 are moved to the left to a predetermined position by the stationary pulling drive assembly, so that the two stationary positioning pins 2224 of the fourth stationary positioning pin assembly 222 are located below the two positioning holes 202 of the third battery clamp 200. Then, the two stationary positioning pins 2224 of the four stationary positioning pin assemblies 222 are moved upward by the stationary cylinder 224, so that the two stationary positioning pins 2224 of the fourth stationary positioning pin assembly 222 and the third stationary positioning pin assembly 222 are... The two stationary positioning pins 2224 of component 222 and the two stationary positioning pin assemblies 222 of the second stationary positioning pin assembly 222 respectively engage with the two positioning holes 202 of the third battery clamp 200, the two positioning holes 202 of the second battery clamp 200, and the two positioning holes 202 of the first battery clamp 200. Then, the stationary material pulling drive assembly drives the four stationary positioning pin assemblies 222 to move to the right to a predetermined position, thereby driving the four battery clamps 200 to move to the right to the predetermined position, so that the third battery clamp 200 is located on the two unpowered roller mechanisms of the lower stationary unit of the first starting stationary module 20 and the two unpowered roller mechanisms of the lower stationary unit of the intermediate stationary module 30. Then, the aforementioned steps are performed, thereby sequentially driving the second battery clamp 200 and the first battery clamp to move onto the two unpowered roller mechanisms of the lower stationary unit of the first starting stationary module 20 and the two unpowered roller mechanisms of the lower stationary unit of the intermediate stationary module 30.

[0083] The operation of the upper stationary unit of the first starting stationary module 20 is the same as that of the lower stationary unit, and will not be described again here. The stationary pulling mechanism of the upper stationary unit can drive the four battery clamps 200 to move sequentially to the two unpowered roller mechanisms of the upper stationary unit of the first starting stationary module 20 and the two unpowered roller mechanisms of the upper stationary unit of the intermediate stationary module 30.

[0084] The intermediate stationary module 30 performs a second stationary treatment on several batteries in the battery clamp 200. The operation of the lower stationary unit of the intermediate stationary module 30 is the same as that of the lower stationary unit of the first starting stationary module 20, and the operation of the upper stationary unit of the intermediate stationary module 30 is the same as that of the upper stationary unit of the first starting stationary module 20. The stationary pulling mechanism of the lower stationary unit of the intermediate stationary module 30 can drive the first four battery clamps 200 to move sequentially to the two unpowered roller mechanisms of the lower stationary unit of the intermediate stationary module 30 and the two unpowered roller mechanisms of the lower stationary unit of the end stationary module 40. The stationary pulling mechanism of the upper stationary unit of the intermediate stationary module 30 can drive the last four battery clamps 200 to move sequentially to the two unpowered roller mechanisms of the upper stationary unit of the intermediate stationary module 30 and the two unpowered roller mechanisms of the upper stationary unit of the end stationary module 40.

[0085] The battery clamps 200 are subjected to a third settling process by the end-point settling module 40: the operation of the lower settling unit of the end-point settling module 40 is the same as that of the lower settling unit of the first starting settling module 20. The settling pulling mechanism of the lower settling unit of the end-point settling module 40 can move the first four battery clamps 200 sequentially onto the two unpowered roller mechanisms of the lower settling unit of the end-point settling module 40 and the two transport roller assemblies of the transport unit 52. The operation of the upper settling unit of the end-point settling module 40 is the same as that of the upper settling unit of the first starting settling module 20. The settling pulling mechanism of the upper settling unit of the end-point settling module 40 can move the last four battery clamps 200 sequentially onto the two unpowered roller mechanisms of the upper settling unit of the end-point settling module 40 and the two transport roller assemblies of the transport unit 52.

[0086] The battery clamp 200 is transported to the second starting point stationary module 60 by the transport device 50. For example, when the fourth battery clamp 200 is located on the two unpowered roller mechanisms of the lower stationary unit of the endpoint stationary module 40 and the two transport roller assemblies of the transport unit 52, the first transport pulling cylinder 5262 drives the transport pulling base plate 5261 to slide to the left, thereby driving the two transport positioning pin assemblies to move to the left. Then, the second transport pulling cylinder 5264 drives the two transport positioning pin assemblies to move to the left, so that the transport pin shafts 52681 of the two transport positioning pin assemblies are located below the two positioning holes 202 of the fourth battery clamp 200. Then, the transport positioning cylinders 5267 of the two transport positioning pin assemblies drive the corresponding transport pin shafts 52681 to move upward, so that the transport pin shafts 52681 of the two transport positioning pin assemblies engage with the two positioning holes 202 of the fourth battery clamp 200. Then, the second conveying and pulling cylinder 5264 drives the two conveying positioning pin assemblies to move to the right to the initial position. Then, the first conveying and pulling cylinder 5262 drives the conveying and pulling base plate 5261 to slide to the right, thereby moving the two conveying positioning pin assemblies to the right to the initial position. At this time, the fourth battery clamp 200 is located within the conveying frame 521. Then, the conveying drive unit drives the conveying unit 52 to slide backward to a predetermined position, thereby moving the fourth battery clamp 200 backward. At this time, the conveying unit 52 is located to the right of the second starting point stationary module 60. Then, the first conveying and pulling cylinder 5262 drives the conveying and pulling base plate 5261 to slide to the left, thereby moving the two conveying positioning pin assemblies to the left. Then, the second conveying and pulling cylinder 5264 drives the two conveying positioning pin assemblies to move to the left, thereby moving the fourth battery clamp 200 to the left to the predetermined position. At this time, the fourth battery clamp 200 is located on the two unpowered roller mechanisms of the two conveying roller assemblies and the lower stationary unit of the second starting point stationary module 60. Then, the corresponding transport pins 52681 are driven downward by the transport positioning cylinders 5267 of the two transport positioning pin assemblies, so that the transport pins 52681 of the two transport positioning pin assemblies are separated from the two positioning holes 202 of the fourth battery clamp 200. Then, the two transport positioning pin assemblies are driven to move to the right to the initial position by the second transport pulling cylinder 5264, and then the transport pulling base plate 5261 is driven to slide to the right by the first transport pulling cylinder 5262, thereby driving the two transport positioning pin assemblies to move to the right to the initial position. After the fourth battery clamp 200 is moved to the bottom of the first breathing component 235 of the lower stationary unit of the second starting stationary module 60 by the stationary pulling mechanism of the lower stationary unit of the second starting stationary module 60, the transport driving unit drives the transport unit 52 to move forward to the initial position. In this way, the transport device 50 transports the fourth battery clamp 200 to the lower stationary unit of the second starting stationary module 60.When the third battery clamp 200 is located on the two unpowered roller mechanisms of the lower stationary unit of the endpoint stationary module 40 and the two transport roller assemblies of the transport unit 52, the aforementioned steps are performed, thereby enabling the third battery clamp 200 to be transported to the lower stationary unit of the second starting stationary module 60. In this way, the second battery clamp 200 and the first battery clamp 200 can be transported to the lower stationary unit of the second starting stationary module 60 in sequence.

[0087] Subsequently, the transport platform 521 is driven upward by the transport up and down drive components, which in turn drives the two transport roller assemblies and the transport pulling mechanism 526 to move upward, so that the two transport roller assemblies correspond to the two unpowered roller mechanisms of the upper stationary unit of the endpoint stationary module 40. In this way, the stationary pulling mechanism of the upper stationary unit of the endpoint stationary module 40 can move the last four battery clamps 200 sequentially onto the two unpowered roller mechanisms of the upper stationary unit of the endpoint stationary module 40 and the two transport roller assemblies of the transport unit 52. Then, the transport device 50 performs the aforementioned steps to sequentially transport the last four battery clamps 200 to the upper stationary unit of the second starting stationary module 60.

[0088] The second starting point stationary module 60 performs a fourth stationary treatment on several batteries within the battery clamp 200. The actions of the lower stationary unit and the upper stationary unit of the second starting point stationary module 60 are the same as those of the lower stationary unit and the upper stationary unit of the first starting point stationary module 20, respectively. The only difference is that the stationary pulling mechanism of the second starting point stationary module 60 drives the battery clamp 200 to move in the opposite direction, i.e., to the left. Thus, the stationary pulling mechanism of the lower stationary unit of the second starting point stationary module 60 can drive the first four battery clamps 200 to move sequentially to the two unpowered roller mechanisms of the lower stationary unit of the second starting point stationary module 60 and the two passive roller assemblies of the second lifting module 90. Similarly, the stationary pulling mechanism of the upper stationary unit of the second starting point stationary module 60 can drive the last four battery clamps 200 to move sequentially to the two unpowered roller mechanisms of the upper stationary unit of the second starting point stationary module 60 and the two passive roller assemblies of the second lifting module 90.

[0089] The second lifting module 90 first transports the first four battery clamps 200 sequentially to the second conveyor line. For example, when the fourth battery clamp 200 is located on the two unpowered roller mechanisms of the lower stationary unit of the second starting stationary module 60 and the two passive roller assemblies of the second lifting module 90, the first lifting and pulling cylinder 152 drives the lifting and pulling base plate 151 to move to the right, so that part of the lifting and pulling base plate 151 extends into the lower mounting position 2141 of the second starting stationary module 60. Then, the second lifting and pulling cylinder 154 drives the two lifting positioning pin assemblies to move to the right to a predetermined position, so that the pin shafts 1571 of the two lifting positioning pin assemblies are below the two positioning holes 202 of the fourth battery clamp 200. Then, the lifting and positioning cylinders 156 of the two lifting positioning pin assemblies drive the corresponding pin shafts 1571 to move upward, so that the pin shafts 1571 of the two lifting positioning pin assemblies respectively engage with the two positioning holes 202 of the fourth battery clamp 200. Then, the first lifting and pulling cylinder 152 drives the lifting and pulling base plate 151 to move to the left to the initial position, thereby driving the two lifting positioning pin assemblies to move to the left to the initial position. Then, the second lifting and pulling cylinder 154 drives the two lifting positioning pin assemblies to move to the left to the initial position. At this time, the fourth battery clamp 200 is located inside the lifting frame 11. Then, the lifting positioning cylinders 156 of the two lifting positioning pin assemblies drive the corresponding pin shafts 1571 to move downward to the initial position, so that the pin shafts 1571 of the two lifting positioning pin assemblies are separated from the two positioning holes 202 of the fourth battery clamp 200. Then, the lifting cylinder 166 drives the two passive roller assemblies to move downward to a predetermined position, so that the fourth battery clamp 200 is located on the multiple active rollers 136 of the two active roller assemblies. Then, the active roller drive assembly drives the multiple active rollers 136 of the two active roller assemblies to rotate. In this way, the rotation of the multiple active rollers 136 of the two active roller assemblies can drive the fourth battery clamp 200 to move to the left to the second conveyor line for conveying the fourth battery clamp 200 through the second conveyor line.

[0090] When the third battery clamp 200 is positioned on the two unpowered roller mechanisms of the lower stationary unit of the second starting stationary module 60 and the two passive roller assemblies of the second lifting module 90, the above steps are then performed, thereby enabling the third battery clamp 200 to move to the left onto the second conveyor line for conveying the fourth battery clamp 200 via the second conveyor line. This process is repeated, thereby sequentially moving the second battery clamp 200 and the first battery clamp 200 to the left onto the second conveyor line.

[0091] The second lifting module 90 sequentially transports the last four battery clamps 200 to the second conveyor line. This step is the same as the previous step, except that before this step, the lifting platform 12 is driven upward by the lifting drive component 14, so that the two passive roller components correspond to the two unpowered roller mechanisms of the upper stationary unit of the second starting stationary module 60. In this way, the stationary pulling mechanism of the upper stationary unit of the second starting stationary module 60 can drive the battery clamps 200 to move onto the two unpowered roller mechanisms and two passive roller components of the upper stationary unit of the second starting stationary module 60. After the battery clamps 200 are located on the multiple active rollers 136 of the two active roller components, the lifting platform 12 is driven downward by the lifting drive component 14, so that the two active roller components correspond to the second conveyor line. Then, the active roller drive component drives the multiple active rollers 136 of the two active roller components to rotate. In this way, the multiple active rollers 136 of the two active roller components can drive the battery clamps 200 to move to the left onto the second conveyor line. Thus, the second lifting module 90 can sequentially transport the last four battery clamps 200 to the second conveyor line for sequential transport.

[0092] This invention utilizes a first settling line and a second settling line. The first settling line includes a first starting settling module 20, an intermediate settling module 30, and an end settling module 40. The second settling line includes a second starting settling module 60. Through the first starting settling module 20, the intermediate settling module 30, the end settling module 40, and the second starting settling module 60, a number of batteries within the battery clamp 200 can undergo a first settling treatment, a second settling treatment, a third settling treatment, and a fourth settling treatment, respectively. This ensures that the electrolyte completely wets the battery. The internal structure of the core ensures battery quality. The first and second stationary lines are arranged in parallel front to back. The first lifting module 10, the first starting stationary module 20, the middle stationary module 30, and the ending stationary module 40 of the first stationary line are connected sequentially from left to right. The second lifting module 10 and the second starting stationary module 60 of the second stationary line are connected sequentially from left to right. The linear structure reduces the width of the production workshop and reduces the flow of the battery clamp 200 between adjacent stationary modules, thereby reducing the overall stationary time and improving production efficiency. The first starting stationary module 20, the intermediate stationary module 30, the end stationary module 40, and the second starting stationary module 60 all include a stationary material pulling mechanism and a breathing mechanism. The stationary material pulling mechanism uses a motor and lead screw drive and a positioning pin that cooperates with the positioning hole 202 of the battery clamp 200 to move the battery clamp 200 to below the breathing component 235. This is low-cost. The breathing mechanism uses a motor and lead screw drive to move several positioning pins 2352 downward to abut against the top of several one-way valves 201 of the battery clamp 200. This is also low-cost. The breathing component 235 can realize the negative pressure, normal pressure, and positive pressure breathing action of the battery, which can ensure that the electrolyte completely wets the inside of the battery cell.

[0093] In other embodiments, the second stationary line further includes a reserved stationary module 70 and a replacement stationary module 80, which are connected from right to left between the second starting stationary module 60 and the second lifting module 90. The structures of the reserved stationary module 70 and the replacement stationary module 80 are the same as those of the second starting stationary module 60, except that the reserved stationary module 70 and the replacement stationary module 80 have removed the breathing mechanism. The stationary frame 21 of the reserved stationary module 70 is connected to the stationary frame 21 of the second starting stationary module 60 and the stationary frame 21 of the replacement stationary module 80, respectively. The lifting frame 11 of the second lifting module 90 is connected to the stationary frame 21 of the replacement stationary module 80. The working principle of the stationary material pulling mechanism of the reserved stationary module 70 and the replacement stationary module 80 is the same as that of the stationary material pulling mechanism of the second starting stationary module 60. The reserved stationary module 70 and the supplementary stationary module 80 are used to store the battery clamp 200. Understandably, the reserved stationary module 70 and the supplementary stationary module 80 can also be equipped with a breathing mechanism according to actual needs.

[0094] In this embodiment, there is one intermediate settling module 30. Understandably, in other embodiments, there can be multiple intermediate settling modules 30, such as two or three. When there are multiple intermediate settling modules 30, they are connected sequentially from left to right between the first starting settling module 20 and the ending settling module 40. Specifically, the settling frames 21 of the multiple intermediate settling modules 30 are sequentially connected between the settling frames 21 of the first starting settling module 20 and the settling frames 21 of the ending settling module 40. Having multiple intermediate settling modules 30 increases the number of battery settling processes, thereby further ensuring that the electrolyte completely wets the interior of the battery cell, further improving battery quality.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
