[0073] Example

[0074] See also Figure 1 , Figure 1 Shown is a schematic structural diagram of the automatic disk loading device 100 provided in this embodiment.

[0075] The automatic loading device 100 provided in this embodiment is used to automatically load multiple battery shells 10 loaded in the base 20 into the material tray 50, and specifically includes an installation bracket 140, a unloading mechanism and a loading mechanism. The unloading mechanism includes a base loading device 110, a battery shell transferring device 120, a turning device 130 and a recovery device 150; the loading mechanism includes a material tray loading device 160, a material tray transferring device 170, a fixing device 180, a tray loading and transferring device 190 and a stacking device 195.

[0076] The bottom support loading device 110, the recovery device 150, the turning device 130, the tray transferring device 170, the fixing device 180 and the tray loading device 160 are arranged in sequence below the mounting bracket 140 along the first direction, and the battery shell transferring device 120, the tray transferring device 190 and the stacking device 195 are movably arranged on the mounting bracket 140 in sequence along the first direction. The battery shell transferring device 120, the tray transferring device 190 and the stacking device 195 can all move in the first direction relative to the mounting bracket 140. Figure 1 The direction indicated by the X arrow is the first direction.

[0077] The bottom tray loading device 110 is used to transport the multiple battery shells 10 loaded in the bottom tray 20 to the first loading station; the battery shell transfer device 120 is used to transfer the multiple battery shells 10 at the first loading station to the flipping device 130; the recycling device 150 is used to recycle the paper tray laid in the bottom tray 20 for supporting the battery shells 10; the flipping device 130 is used to drive the multiple battery shells 10 to flip from the first state to the second state.

[0078] The tray loading device 160 is used to transport multiple trays 50 loaded in the fixture 40 to the second loading station; the tray transferring device 170 is used to move the multiple trays 50 at the second loading station away from the fixture 40; the tray loading device 160 is also used to transport the unloaded fixture 40 at the second loading station to the stacking station; the fixing device 180 is used to fix the multiple trays 50 on the tray transferring device 170 in sequence; the tray transfer device 190 is used to transfer the multiple battery shells 10 that have been flipped by the flipping device 130 to the tray 50 fixed by the fixing device 180; the stacking device 195 is used to transfer the tray 50 fixed by the fixing device 180 and loaded with battery shells 10 to the fixture 40 at the stacking station for stacking.

[0079] Please refer to Figure 2 , Figure 2 FIG. 1 is a schematic structural diagram of a bottom support loading device 110 .

[0080] The bottom support feeding device 110 is used to convey the multiple battery shells 10 loaded in the bottom support 20 to the first feeding station. In fact, the multiple battery shells 10 are arranged in sequence in the bottom support 20, and a separation paper 30 is provided between adjacent battery shells 10. The multiple battery shells 10 are all in an inverted state with the opening facing downward, and this inverted state is defined as the first state, and a paper support is provided between the opening of the battery shell 10 and the bottom support 20.

[0081] In this embodiment, the bottom support loading device 110 includes a first roller conveyor line 111, a limiting rail 112 and a first driving member 113. The limiting rail 112 extends along the transmission direction of the first roller conveyor line 111, and defines a channel for conveying product components above the first roller conveyor line 111. The first driving member 113 is transmission-connected to the limiting rail 112 for adjusting the width of the limiting rail 112 to accommodate bottom supports 20 of different sizes.

[0082] In fact, in this embodiment, the number of the limiting rails 112 is two, and the number of the corresponding first driving members 113 is also two, and the two first driving members 113 respectively adjust the width of the two limiting rails 112. It can be understood that in actual application, the bottom bracket 20 is loaded by one end of the limiting rail 112 corresponding to the input end of the first roller conveyor line 111, and enters the channel defined by the limiting rail 112. Under the conveying action of the first roller conveyor line 111, the bottom bracket 20 moves along the limiting rail 112 until it reaches the first loading station.

[0083] The limiting track 112 serves as a limiting guide for the product components. Considering that in actual applications, the sizes of the base tray 20 corresponding to battery shells 10 of different specifications are different, the width requirements for the limiting track 112 are also different. In order to adapt to base trays 20 of different sizes, the first drive member 113 adjusts the width of the limiting track 112. When the width of the base tray 20 to be loaded is larger, the first drive member 113 increases the width of the limiting track 112; when the width of the base tray 20 to be loaded is smaller, the first drive member 113 decreases the width of the limiting track 112.

[0084] It should be noted that in other embodiments, other conveying structures may be used to replace the first roller conveyor line 111, such as a conveyor belt, etc., and the same configuration of the width-adjustable limit rail 112 can adapt to different sizes of the bottom bracket 20. It is understandable that the size of the bottom bracket 20 is usually determined by the specification size of the battery shell 10.

[0085] In this embodiment, the bottom support loading device 110 also includes a first stop assembly 114, which is arranged on an end of the limiting track 112 corresponding to the end of the conveying direction of the first roller conveyor line 111, and the first stop assembly 114 is used to stop the bottom support 20 to limit the bottom support 20 at the first loading station.

[0086] It can be seen that the first loading station in this embodiment is the end of the conveying direction of the first roller conveyor line 111. When the first roller conveyor line 111 conveys the base 20 to the first loading station, the first stopper assembly 114 blocks the current base 20 and prevents the base 20 from leaving the first loading station, so that the battery shell transfer device 120 moves to the first loading station to pick up the battery shell 10.

[0087] The bottom support loading device 110 also includes a second stop assembly 115, which is arranged in the limiting track 112 and is upstream of the first stop assembly 114 in the transmission direction of the first roller conveyor line 111. The second stop assembly 115 is used to stop the bottom support 20 at the rear when the first stop assembly 114 stops the bottom support 20 in front.

[0088] In actual application, among two adjacent base trays 20, when the front base tray 20 reaches the first loading station and is stopped by the first stop assembly 114, the second stop assembly 115 extends out of the surface of the first roller conveyor line 111 to stop the rear base tray 20 to prevent the rear base tray 20 from continuing to move forward and hitting the front base tray 20.

[0089] In this embodiment, the first stopper assembly 114 and the second stopper assembly 115 are both arranged below the first roller conveyor line 111, and are both automatically retractable structures. When the corresponding base 20 needs to be stopped, they are extended to protrude from the surface of the first roller conveyor line 111, and when the stop needs to be released, they are retracted to below the surface of the first roller conveyor line 111.

[0090] Please refer to Figure 3 and Figure 4 , Figure 3 FIG. 1 is a schematic diagram showing the connection structure between the battery shell transfer device 120 and the mounting bracket 140. Figure 4 FIG. 1 is a schematic structural diagram of a battery shell transfer device 120 .

[0091] The battery shell transferring device 120 includes a first moving body 121 and a first transferring module 122. The first transferring module 122 is arranged on the first moving body 121. The first transferring module 122 is provided with multiple shell clamping assemblies and a second driving member 123. The shell clamping assembly is used to take or release the battery shell 10. The second driving member 123 is transmission-connected to the multiple shell clamping assemblies and is used to adjust the spacing between the multiple shell clamping assemblies. The first moving body 121 is used to drive the first transferring module 122 to move between the first loading station and the flipping device 130.

[0092] The mounting bracket 140 is provided with a first guide rail 141 extending in the first direction, the first moving body 121 is slidably matched with the first guide rail 141, and the first loading station and the flipping device 130 are located below the mounting bracket 140 and are spaced apart in the first direction.

[0093] In fact, the battery shell transferring device 120 also includes a third driving member 127, a fourth driving member 128 and a fifth driving member 129. The third driving member 127 is arranged on the first moving body 121, and is used to drive the first moving body 121 to slide along the first guide rail 141; the fourth driving member 128 is arranged on the first moving body 121 and is connected to the fifth driving member 129, and is used to drive the fifth driving member 129 to move in the second direction; the fifth driving member 129 is connected to the first transferring module 122, and is used to drive the first transferring module 122 to move in the third direction; the first direction, the second direction and the third direction are angled with each other.

[0094] The second direction is Figure 1 The direction indicated by the Y arrow is the third direction. Figure 1 In fact, the first direction and the second direction are two directions perpendicular to each other in the horizontal plane, and the third direction is the vertical direction, that is, the first direction, the second direction, and the third direction are perpendicular to each other.

[0095] The third driving member 127 drives the first moving body 121 to move in the first direction, driving the first transfer module 122 to move in the first direction, so as to transfer the multiple battery shells 10 of the first loading station to the flipping device 130; the fourth driving member 128 drives the fifth driving member 129 to move in the second direction, driving the first transfer module 122 to move in the second direction, so as to realize the first transfer module 122 selectively fixing the battery shells 10 in the two limiting rails 112; the fifth driving member 129 drives the first transfer module 122 to move in the third direction, so as to realize the height adjustment of the first transfer module 122.

[0096] In fact, a first rack 142 is also provided on the mounting bracket 140, and the extension direction of the first rack 142 is parallel to the first direction. A first gear 1211 is also provided on the first moving body 121, and the first gear 1211 is meshed with the first rack 142. The third driving member 127 is connected to the first gear 1211, and is used to drive the first gear 1211 to roll along the first rack 142.

[0097] It is understandable that, in actual application, the third driving member 127 can drive the first gear 1211 to rotate forward to roll toward one end of the first rack 142, thereby driving the first moving body 121 to move toward one end in the first direction. The third driving member 127 can also drive the first gear 1211 to rotate reversely to roll toward the other end of the first rack 142, thereby driving the first moving body 121 to move toward the other end in the first direction. It can be seen that through the forward and reverse rotation of the first gear 1211, the reciprocating motion of the first moving body 121 between the first loading station and the flipping device 130 can be achieved.

[0098] Please refer to Figure 5 and Figure 6 , Figure 5 FIG. 1 is a schematic diagram showing the structure of the first transfer module 122 in one viewing angle. Figure 6 It is a schematic diagram of the structure of the variable distance transfer device from another perspective.

[0099] The first transfer module 122 provided in this embodiment is also provided with multiple transmission components, and the multiple transmission components are respectively connected to the multiple shell clamp components. The multiple shell clamp components are arranged in sequence in the first direction. The second driving member 123 is connected to the multiple transmission components and is used to drive the multiple transmission components to move so as to adjust the spacing between the multiple clamp components in the first direction.

[0100] In actual applications, the second driving member 123 drives multiple transmission components to move, driving multiple jaw components to gather or disperse in the first direction, thereby adjusting the spacing of multiple jaw components, thereby meeting the synchronous transfer requirements of batch battery shells 10 with different spacings.

[0101] In this embodiment, multiple transmission components include a first transmission component 210 and a second transmission component 220. The first transmission component 210 includes a first positive-rotating screw rod 211 and a first screw rod seat 212 that cooperate with each other. The first positive-rotating screw rod 211 is parallel to the first direction. The first positive-rotating screw rod 211 is rotatably arranged on the first transfer module 122 and is transmission-connected to the second driving member 123. The first screw rod seat 212 is slidingly matched with the first transfer module 122.

[0102] The second transmission assembly 220 includes a first reverse-rotating screw 221 and a second screw seat 222 that cooperate with each other. The first reverse-rotating screw 221 is rotatably arranged on the first transfer module 122 and is coaxially connected to the first forward-rotating screw 211 through a coupling. The second screw seat 222 is slidably matched with the first transfer module 122. The plurality of clamping jaw assemblies include a first clamping jaw assembly 124 and a second clamping jaw assembly 230. The first clamping jaw assembly 124 is connected to the first screw seat 212, and the second clamping jaw assembly 230 is connected to the second screw seat 222.

[0103] It can be understood that the rotation direction of the first forward-rotating screw rod 211 is opposite to that of the first reverse-rotating screw rod 221. In this embodiment, the rotation direction of the first forward-rotating screw rod 211 is defined as forward, and the rotation direction of the first reverse-rotating screw rod 221 is defined as reverse. The first forward-rotating screw rod 211 is transmission-connected with the second driving member 123. When the second driving member 123 is in operation, the second driving member 123 drives the first forward-rotating screw rod 211 and the first reverse-rotating screw rod 221 to rotate relative to the first transfer module 122, so that the first forward-rotating screw rod 211 and the first reverse-rotating screw rod 221 respectively drive the first screw rod seat 212 and the second screw rod seat 222 to slide on the first transfer module 122. Since the first forward-rotating screw rod 211 and the first reverse-rotating screw rod 221 have opposite rotation directions, the sliding directions of the first screw rod seat 212 and the second screw rod seat 222 are opposite, and the two move toward or away from each other in the first direction.

[0104] The multiple transmission components also include a third transmission component 240 and a fourth transmission component 250. The third transmission component 240 includes a second positive-rotating screw rod 241 and a third screw rod seat 242 that cooperate with each other. The second positive-rotating screw rod 241 is rotatably arranged on the first transfer module 122 and is parallel to the first positive-rotating screw rod 211. The third screw rod seat 242 is slidably matched with the first transfer module 122.

[0105] The fourth transmission assembly 250 includes a second counter-rotating screw 251 and a fourth screw seat 252 that cooperate with each other. The second counter-rotating screw 251 is rotatably arranged on the first transfer module 122 and is coaxially connected to the second forward-rotating screw 241 through a coupling. The fourth screw seat 252 is slidably matched with the first transfer module 122.

[0106] A first transmission pulley 260 is also provided on the first transfer module 122, and the first anti-rotating screw 221 is connected to the second anti-rotating screw 251 through the first transmission pulley 260; the multiple jaw assemblies also include a third jaw assembly 125 and a fourth jaw assembly 270 arranged in sequence between the first jaw assembly 124 and the second jaw assembly 230, the third jaw assembly 125 is connected to the third screw seat 242, and the fourth jaw assembly 270 is connected to the fourth screw seat 252.

[0107] The second forward-rotating screw rod 241 and the second reverse-rotating screw rod 251 have opposite rotation directions, and the second forward-rotating screw rod 241 and the first forward-rotating screw rod 211 have the same rotation direction, both in the forward direction; the second reverse-rotating screw rod 251 and the first reverse-rotating screw rod 221 have the same rotation direction, both in the reverse direction. Since the first reverse-rotating screw rod 221 is connected to the second reverse-rotating screw rod 251 through the first transmission pulley 260, when the second driving member 123 drives the first forward-rotating screw rod 211 to drive the first reverse-rotating screw rod 221 to rotate, the first reverse-rotating screw rod 221 drives the second reverse-rotating screw rod 251 and the second forward-rotating screw rod 241 to rotate through the first transmission pulley 260.

[0108] Similarly, the second forward-rotating screw 241 and the second reverse-rotating screw 251 respectively drive the third screw seat 242 and the fourth screw seat 252 to slide on the first transfer module 122. Since the second forward-rotating screw 241 and the second reverse-rotating screw 251 rotate in opposite directions, the sliding directions of the third screw seat 242 and the fourth screw seat 252 are opposite, and the two move toward each other or away from each other in the first direction. Since the second forward-rotating screw 241 and the first forward-rotating screw 211 rotate in the same direction, and the second reverse-rotating screw 251 and the first reverse-rotating screw 221 rotate in the same direction, the sliding directions of the third screw seat 242 and the first screw seat 212 are the same, and the sliding directions of the fourth screw seat 252 and the second screw seat 222 are the same.

[0109] Since the first screw seat 212, the third screw seat 242, the fourth screw seat 252 and the second screw seat 222 are arranged in sequence in the first direction, when the second driving member 123 is running, the first forward-rotating screw 211, the first reverse-rotating screw 221, the second forward-rotating screw 241 and the second reverse-rotating screw 251 are linked to drive the first screw seat 212, the third screw seat 242, the fourth screw seat 252 and the second screw seat 222 to gather or disperse in the first direction, and drive the first clamping jaw assembly 124, the third clamping jaw assembly 125, the fourth clamping jaw assembly 270 and the second clamping jaw assembly 230 to gather or disperse in the first direction, thereby realizing the adjustment of the spacing between multiple clamping jaw assemblies.

[0110] Please refer to Figure 7 , Figure 7 FIG. 2 is a schematic structural diagram of the first transmission pulley 260 .

[0111] In this embodiment, the first transmission pulley 260 includes a first driving wheel 261, a first driven wheel 262 and a first conveyor belt 263 spanning between the first driving wheel 261 and the first driven wheel 262, the first anti-rotating screw rod 221 is coaxially connected to the first driving wheel 261, the second anti-rotating screw rod 251 is coaxially connected to the first driven wheel 262, and the radius of the first driving wheel 261 is smaller than the radius of the first driven wheel 262.

[0112] When the first reverse-rotating screw 221 rotates, the first driving wheel 261 rotates synchronously, and the first driven wheel 262 is driven to rotate through the first conveyor belt 263, thereby driving the second reverse-rotating screw 251 to rotate synchronously. Since the radius of the first driving wheel 261 is smaller than the radius of the first driven wheel 262, the rotation angular velocity of the first driving wheel 261 is greater than the rotation angular velocity of the first driven wheel 262. The first transmission pulley 260 is equivalent to a reducer, which realizes the high-speed rotation of the first sinusoidal screw and the first reverse-rotating screw 221, and the low-speed rotation of the second positive screw 241 and the second reverse-rotating screw 251. This ensures that the sliding speed of the first screw seat 212 and the second screw seat 222 at both ends of the arrangement queue is faster, and the sliding speed of the third screw seat 242 and the fourth screw seat 252 in the middle of the arrangement queue is slower, thereby ensuring that the spacing between any two adjacent jaw assemblies in the first direction is equal.

[0113] It is understandable that the widths of the threads on the first positive-rotating screw rod 211, the first reverse-rotating screw rod 221, the second positive-rotating screw rod 241 and the second reverse-rotating screw rod 251 in this embodiment are equal. In another embodiment, the first driving wheel 261 and the first driven wheel 262 of the first transmission pulley 260 can also be set to have the same radius, the thread widths of the first positive-rotating screw rod 211 and the first reverse-rotating screw rod 221 are larger, and the thread widths of the second positive-rotating screw rod 241 and the second reverse-rotating screw rod 251 are smaller, which can also make the first screw rod seat 212 and the second screw rod seat 222 at both ends of the arrangement queue slide faster, and the third screw rod seat 242 and the fourth screw rod seat 252 in the middle of the arrangement queue slide slower.

[0114] Regarding the sliding cooperation between each screw seat and the first transfer module 122, in this embodiment, a guide rail 1221 is provided on the first transfer module 122, and the guide rail 1221 is parallel to the first direction. The first screw seat 212, the second screw seat 222, the third screw seat 242 and the fourth screw seat 252 are slidingly cooperated with the guide rail 1221.

[0115] Please refer to Figure 8 and Fig. 9 , Figure 8 is a schematic diagram of the structure of the first clamping jaw assembly 124 in one viewing angle, Fig. 9It is a schematic structural diagram of the first clamping jaw assembly 124 from another perspective.

[0116] In this embodiment, the first clamping jaw assembly 124 includes a first body 1241 , a first compensation assembly 1242 and a first clamping jaw 1248 . The first body 1241 is connected to the first screw seat 212 , and the first clamping jaw 1248 is connected to the first body 1241 via the first compensation assembly 1242 .

[0117] Please refer to Fig.10 , Fig.10 Schematic diagram of the structure of the third clamping jaw assembly 125.

[0118] A third pushing member is provided on the third clamping jaw assembly 125, and the third pushing member is used to push the first compensation assembly 1242 to move relative to the first main body 1241 when the first clamping jaw assembly 124 and the third clamping jaw assembly 125 are separated by a first preset distance, so as to drive the first clamping jaw 1248 to move relative to the first main body 1241 close to the third clamping jaw assembly 125.

[0119] The first clamping jaw 1248 is used to take and place the battery shell 10. In actual application, when the first clamping jaw assembly 124 and the third clamping jaw assembly 125 are at a first preset distance, the third pusher pushes the first compensation assembly 1242 to move relative to the first body 1241, thereby driving the first clamping jaw 1248 to move relative to the first body 1241 close to the third clamping jaw assembly 125. It can be seen that through the coordinated action of the third pusher and the first compensation assembly 1242, the movement compensation of the third clamping jaw 1254 can be achieved, avoiding the restriction of the structural interference between the first body 1241 and the third clamping jaw assembly 125, resulting in the first direction The range of motion of the first clamping jaw 1248 is limited, thereby improving the adjustable range of the distance between the first clamping jaw 1248 and the third clamping jaw assembly 125.

[0120] Specifically, the first compensation component 1242 includes a first pulley 1243, a first supporting member 1244, a first slider 1245 and a first elastic member 1246. The first pulley 1243 and the first elastic member 1246 are both arranged on the first main body 1241, and the first supporting member 1244 and the first slider 1245 are respectively connected to the two sides of the first pulley 1243.

[0121] The extension direction of the first elastic member 1246 is parallel to the first direction. The two ends of the first elastic member 1246 respectively abut against the first main body 1241 and the first slider 1245. The first clamp 1248 is connected to the first slider 1245. The first abutting member 1244 is used to drive the first pulley 1243 to rotate under the push of the third pushing member, so as to drive the first slider 1245 to move toward the direction close to the third clamp assembly 125 and compress the first elastic member 1246.

[0122] When the third pushing member pushes the first supporting member 1244 to move in the direction away from the third clamping jaw assembly 125, the first supporting member 1244 drives the first pulley 1243 to rotate, thereby driving the first slider 1245 on the other side of the first pulley 1243 to move in the direction close to the third clamping jaw assembly 125 and compressing the first elastic member 1246, thereby driving the first clamping jaw 1248 to further move in the direction close to the third clamping jaw assembly 125.

[0123] The first elastic member 1246 has a reset function. During the process of the first clamping jaw assembly 124 and the third clamping jaw assembly 125 moving away from each other, the first elastic member 1246 releases elastic potential energy and gradually extends to ensure that the third pusher and the first abutting member 1244 always abut against each other before the third pusher and the first abutting member 1244 separate. When the first clamping jaw assembly 124 and the third clamping jaw assembly 125 move relative to each other until the distance exceeds the first preset distance, the third pusher and the first abutting member 1244 are out of contact, and at this time, the first clamping jaw 1248 completes the reset under the thrust of the first elastic member 1246.

[0124] In fact, the third clamping jaw assembly 125 includes a third main body 1252, a third compensation assembly 1253 and a third clamping jaw 1254. The third main body 1252 is connected to the third screw seat 242. The third pushing member is arranged on the third main body 1252. The third clamping jaw 1254 is connected to the third main body 1252 through the third compensation assembly 1253.

[0125] A first pushing member 1247 is provided on the first main body 1241. The first pushing member 1247 is used to push the third compensation assembly 1253 to move relative to the third main body 1252 when the first clamping jaw assembly 124 and the third clamping jaw assembly 125 are separated by a second preset distance, so as to drive the third clamping jaw 1254 to move relative to the third main body 1252 close to the fourth clamping jaw assembly 270.

[0126] The third clamping jaw 1254 is used to take and place the battery shell 10. In actual application, when the first clamping jaw assembly 124 and the third clamping jaw assembly 125 are close to each other to the second preset distance, the first pusher 1247 pushes the third compensation assembly 1253 to move relative to the third body 1252, so that the third compensation assembly 1253 drives the third clamping jaw 1254 to move relative to the third body 1252 close to the fourth clamping jaw assembly 270. It can be seen that through the coordinated action of the first pusher 1247 and the third compensation assembly 1253, the movement compensation of the third clamping jaw 1254 can be achieved, avoiding the structural interference restriction of the third body 1252 and the fourth clamping jaw assembly 270, resulting in the third clamping jaw 1254 The range of motion in the first direction is limited, thereby improving the adjustable range of the distance between the third clamping jaw 1254 and the fourth clamping jaw assembly 270.

[0127] Specifically, the third compensation assembly 1253 includes a third slider 1255 and a third elastic member 1256. The third slider 1255 is slidably matched with the third body 1252. The third elastic member 1256 is disposed on the third body 1252, and the extension direction of the third elastic member 1256 is parallel to the first direction. One end of the third elastic member 1256 away from the first clamping jaw assembly 124 abuts against the third body 1252, and one end of the third elastic member 1256 close to the first clamping jaw assembly 124 abuts against the third slider 1255. The third clamping jaw 1254 is connected to the third slider 1255. The third slider 1255 is used to move close to the fourth clamping jaw assembly 270 under the push of the first pusher 1247 and compress the third elastic member 1256.

[0128] Similarly, the third elastic member 1256 plays a role in resetting the third clamping jaw 1254. When the first clamping jaw assembly 124 and the third clamping jaw assembly 125 move away from each other, the third elastic member 1256 releases elastic potential energy and gradually stretches to ensure that the first pusher 1247 and the third slider 1255 always abut against each other before the first clamping jaw assembly 124 and the third clamping jaw assembly 125 are separated. When the first clamping jaw assembly 124 and the third clamping jaw assembly 125 move relative to each other until the distance exceeds the second preset distance, the first pusher 1247 and the third slider 1255 are out of contact, and the third clamping jaw 1254 is reset under the thrust of the third elastic member 1256.

[0129] Please refer to Fig.11 and Fig.12 , Fig.11 FIG. 2 is a schematic diagram showing the structure of the second clamping jaw assembly 230 in one viewing angle. Fig.12 FIG. 2 is a schematic structural diagram of the second clamping jaw assembly 230 from another viewing angle.

[0130] In fact, in this embodiment, the second clamping jaw assembly 230 has the same structure as the first clamping jaw assembly 124. The second clamping jaw assembly 230 includes a second body 231, a second compensation assembly 232 and a second clamping jaw 233. The second body 231 is connected to the second screw seat 222, and the second clamping jaw 233 is connected to the second body 231 through the second compensation assembly 232.

[0131] Please refer to Fig.13 , Fig.13 Shown is a schematic structural diagram of the fourth clamping jaw assembly 270.

[0132] A fourth pushing member 271 is provided on the fourth clamping jaw assembly 270. The fourth pushing member 271 is used to push the second compensation assembly 232 to move relative to the second body 231 when the second clamping jaw assembly 230 and the fourth clamping jaw assembly 270 are separated by a third preset distance, so as to drive the second clamping jaw 233 to move relative to the second body 231 close to the fourth clamping jaw assembly 270.

[0133] In this embodiment, the fourth clamping jaw assembly 270 has exactly the same structure as the third clamping jaw assembly 125, including a fourth main body 272, a fourth compensation assembly 273 and a fourth clamping jaw 274. The fourth main body 272 is connected to the fourth screw seat 252, and the fourth pushing member 271 is arranged on the fourth main body 272. The fourth clamping jaw 274 is connected to the fourth main body 272 through the fourth compensation assembly 273.

[0134] A second pushing member 234 is provided on the second main body 231. The second pushing member 234 is used to push the fourth compensation assembly 273 to move relative to the fourth main body 272 when the second clamping jaw assembly 230 and the fourth clamping jaw assembly 270 are separated by a fourth preset distance, so as to drive the fourth clamping jaw 274 to move relative to the fourth main body 272 close to the third clamping jaw assembly 125.

[0135] In this embodiment, the coordinated action of the first compensation component 1242 and the third pushing member realizes compensation for the movement of the first jaw 1248 in the first direction, and increases the adjustable range of the distance between the first jaw 1248 and the third jaw 1254 in the first direction; the coordinated action of the third compensation component 1253 and the first pushing member 1247 realizes compensation for the movement of the third jaw 1254 in the first direction, and increases the adjustable range of the distance between the third jaw 1254 and the fourth jaw 274 in the first direction.

[0136] The coordinated action of the second compensation component 232 and the fourth pushing member 271 realizes compensation for the movement of the second jaw 233 in the first direction, and increases the adjustable range of the distance between the second jaw 233 and the fourth jaw 274 in the first direction; the coordinated action of the fourth compensation component 273 and the second pushing member 234 realizes compensation for the movement of the fourth jaw 274 in the first direction, and further increases the adjustable range of the distance between the third jaw 1254 and the fourth jaw 274 in the first direction.

[0137] In this embodiment, a pressing assembly 126 is also provided on the first transfer module 122. The pressing assembly 126 is located at one end of the arrangement queue composed of multiple shell clamp assemblies. The pressing assembly 126 is used to press the remaining battery shells 10 in the bottom tray 20 when the multiple shell clamp assemblies take part of the battery shells 10 in the bottom tray 20.

[0138] In other words, the pressing assembly 126 is at one end of the arrangement queue composed of multiple shell clamp assemblies in the first direction. In actual applications, there are situations where the multiple shell clamp assemblies cannot move all the battery shells 10 in the base 20 at one time. At this time, if the battery shell 10 in the base 20 adjacent to the multiple battery shells 10 fixed in sequence by the multiple shell clamp assemblies is not fixed, its own state may be affected and it may be tripped or deflected.

[0139] In this embodiment, the pressing assembly 126 is used to press and fix the battery shell 10 adjacent to the multiple battery shells 10 that are sequentially fixed by the multiple shell jaw assemblies. After the multiple shell jaw assemblies take the corresponding multiple battery shells 10 away from the bottom bracket 20, the pressing assembly 126 releases the fixation of the battery shell 10, thereby preventing the state of the battery shell 10 from being affected. The pressing assembly 126 is actually a retractable mechanism, which can be a cylinder, etc., and the pressing and fixing and releasing of the battery shell 10 are achieved by the extension and retraction of the telescopic end in the vertical direction.

[0140] Please refer to Fig.14 , Fig.14 FIG. 1 is a schematic structural diagram of the flipping device 130 .

[0141] The flipping device 130 includes a flipping drive 131 and a plurality of flipping platforms 132. The flipping drive 131 is transmission-connected to the plurality of flipping platforms 132. The plurality of flipping platforms 132 are each provided with a fixing assembly 1321 for fixing the battery shell 10. The flipping drive 131 is used to drive the plurality of flipping platforms 132 to flip, so as to drive the plurality of battery shells 10 to flip from the first state to the second state.

[0142] In fact, the second state is a horizontal state, that is, the battery shell 10 is in a state where the opening is facing horizontally. In other words, to flip from the first state to the second state, the flipping platform 132 needs to flip 90°.

[0143] The automatic loading device 100 provided in this embodiment also includes a blowing device, which is arranged on the mounting bracket 140 and is located between the flipping device 130 and the bottom support loading device 110, and is used to blow off the isolation paper 30 attached to the battery shell 10 when the battery shell transferring device 120 loads the battery shell 10 from the first loading station to the flipping device 130.

[0144] When the battery shell transferring device 120 places the battery shell 10 in the first state on the flipping platform 132 and is fixed by the fixing component 1321, there may be some isolation paper 30 that has not been blown off and is still attached to the large surface of the battery shell 10. In this case, the flipping platform 132 drives the battery shell 10 to flip from the first state to the second state so that the remaining isolation paper 30 can fall freely.

[0145] It is understandable that, in the process of the flipping platform 132 driving the battery shell 10 to flip, the blowing device can still continue to blow air toward the battery shell 10 to further ensure that all the remaining isolation paper 30 falls off.

[0146] In this embodiment, the flipping device 130 also includes multiple second transmission pulleys 133, and multiple flipping platforms 132 are arranged in sequence. Any two adjacent flipping platforms 132 are connected by a second transmission pulley 133, and one or more second transmission pulleys 133 in the multiple flipping platforms 132 are connected to the flipping drive member 131.

[0147] Since the multiple flip platforms 132 form a linked overall structure through the multiple second transmission pulleys 133, when the flip driving member 131 drives the flip platform 132 or the second transmission pulley 133 to move, all the flip platforms 132 can be flipped synchronously, so that the multiple battery shells 10 can be flipped from the first state to the second state at one time.

[0148] In this embodiment, the flipping device 130 also includes a device body 134, on which two mounting beams 1341 are arranged in parallel and at intervals, a plurality of flipping platforms 132 are spanned between the two mounting beams 1341 and are arranged in sequence and at intervals in the length direction of the mounting beams 1341, and a plurality of second transmission pulleys 133 are alternately arranged on the two mounting beams 1341 in sequence.

[0149] The flipping platform 132 includes a rotating shaft 1322 and a platform body 1323 which are connected to each other. The fixing component 1321 is arranged on the platform body 1323. The platform body 1323 is located between two mounting beams 1341. One end of the rotating shaft 1322 is connected to a second transmission pulley 133, and the other end of the rotating shaft 1322 is connected to the flipping driving member 131 or another second transmission pulley 133.

[0150] In fact, in this embodiment, one of the multiple flip platforms 132 is located at the end of the arrangement queue, and one end of its rotating shaft 1322 is connected to a flip driving member 131, and the other end is connected to a second transmission pulley 133. The flip driving member 131 and the second transmission pulley 133 are respectively arranged on two mounting beams 1341, and the second transmission pulley 133 is connected to the rotating shaft 1322 of the adjacent flip platform 132.

[0151] In actual application, the flip driving member 131 drives the rotating shaft 1322 connected thereto to rotate, and the rotating shaft 1322 drives the correspondingly connected platform body 1323 to rotate, and the fixing assembly 1321 provided on the platform body 1323 drives the battery shell 10 to flip. The rotating shaft 1322 drives the second transmission pulley 133 connected to the other end thereof to move, and then drives the next rotating shaft 1322 to rotate, so that the multiple platform bodies 1323 corresponding to the multiple flipping platforms 132 are flipped synchronously, so that the multiple battery shells 10 are flipped synchronously from the first state to the second state.

[0152] Please refer to Fig.15 , Fig.15Shown is a schematic structural diagram of the recovery device 150.

[0153] In this embodiment, the recycling device 150 includes a recycling conveying member 151, a paper pulling support assembly 152 and a guide slide 153. The paper pulling support assembly 152 and the guide slide 153 are arranged above the recycling conveying member 151 at an interval. The paper pulling support assembly 152 is used to pull the empty paper support at the loading station onto the guide slide 153. The guide slide 153 is used to guide the paper support to slide onto the recycling conveying member 151. The recycling conveying member 151 is used to transport the paper support to the recycling station.

[0154] In actual application, when the battery shell transfer device 120 moves multiple battery shells 10 in the bottom tray 20 at the first loading station away from the bottom tray 20, multiple paper trays are left in the bottom tray 20. At this time, the paper tray pulling component 152 pulls the paper tray in the bottom tray 20 onto the guide slide 153. The guide slide 153 actually has a guide slope. After the paper tray reaches the guide slide 153, it slides down to the recovery conveyor 151 under the guide action of the guide slope. The recovery conveyor 151 then transports the paper tray to the recovery station. In this embodiment, the recovery conveyor 151 is a transmission belt.

[0155] Please refer to Fig.16 , Fig.16 Shown is a schematic structural diagram of a tray loading device 160 .

[0156] The tray loading device 160 includes a second roller conveyor line 161, a limiter 162 and a positioning assembly 163. The limiter 162 and the positioning assembly 163 are respectively arranged at the two ends of the second roller conveyor line 161 along its conveying direction. The limiter 162 is used to limit the fixture 40 loaded with the tray 50 at the second loading station, and the positioning assembly 163 is used to limit the unloaded fixture 40 at the stacking station.

[0157] It can be seen that the second loading station is at one end of the second roller conveyor line 161 close to the unloading mechanism in the first direction, and the stacking station is at one end of the roller conveyor line away from the unloading mechanism in the first direction. The second roller conveyor line 161 can reciprocate the clamp 40 between the second loading station and the stacking station.

[0158] In actual application, the fixture 40 fully loaded with the tray 50 is placed on the stacking station, and the second roller conveyor line 161 conveys the fixture 40 to the second loading station. At this time, the limiter 162 limits the fixture 40 loaded with the tray 50 at the second loading station. After the tray transfer device 170 removes multiple trays 50 from the fixture 40, the second roller conveyor line 161 rotates in the opposite direction to convey the empty fixture 40 back to the stacking station, and the positioning assembly 163 limits the empty fixture 40 at the stacking station, waiting for the stacking device 195 to stack the trays 50 fully loaded with battery shells 10 on the fixture 40 in sequence.

[0159] In this embodiment, the tray loading device 160 also includes a clamping assembly 164, which is arranged between the limit member 162 and the positioning assembly 163. The clamping assembly 164 is used to push the clamp 40 against the limit member 162 when the second roller conveyor line 161 conveys the clamp 40 loaded with the tray 50 to the second loading station.

[0160] In fact, the pressing assembly 164 is a retractable structure. When the clamp 40 reaches the second loading station and one end thereof abuts against the stopper 162, the pressing assembly 164 extends to abut against one end of the clamp 40 away from the stopper 162, thereby clamping and fixing the clamp 40 together with the stopper 162. After the tray transfer device 170 removes the plurality of trays 50 from the clamp 40, the pressing assembly 164 contracts to release the abutment on the clamp 40, and the second roller conveyor line 161 rotates in the opposite direction to convey the empty clamp 40 back to the stacking station.

In fact, the bottom of the fixture 40 is provided with a hollow structure to allow the lifting cantilever 171 of the material tray transfer device 170 to extend into the bottom of the stacking structure of the material tray 50.

[0164] When the tray loading device 160 delivers the fully loaded fixture 40 to the second loading station, the lifting arm 171 extends into the hollow structure at the bottom of the fixture 40, and then the lifting drive 172 drives the lifting arm 171 to move vertically upward along the fixed bracket 173, thereby lifting the multiple trays 50 upward. After all the trays 50 leave the top of the four columns of the fixture 40, the loading device delivers the empty fixture 40 back to the stacking station.

[0165] The fixing device 180 is located in the upper area of ​​the lifting cantilever 171, and the fixing device 180 includes a first clamping component 181 and a second clamping component 182.
