[0041] The present invention is further described in detail below in conjunction with the accompanying drawings. The automatic container battery packing system is set on one side of the container to transport the batteries from the initial delivery line and load them into the container. Figure 1 As shown, the automatic container battery packing system includes an elevator 1, a batching warehouse 2 and an installation station 3; the delivery line transports the batteries piece by piece to the elevator 1; the elevator 1 receives two consecutive batteries from the delivery line to form a battery pack, and transports the battery pack to the batching warehouse 2; the batching warehouse 2 includes two layers of batching conveying devices 22, each layer of batching conveying devices 22 receives and transports the battery pack from the elevator 1, and then sends the batteries in the battery pack to the installation station 3 piece by piece; the installation station 3 receives a single battery from the batching warehouse 2 and sends the battery into the container. In order to cooperate with the above-mentioned packing system and improve the packing efficiency, the layer where the delivery line is located needs to be higher than the layer where the packing system and the container are located, so as to achieve an efficient battery transportation.

[0042] The above automatic packing system corresponds to an automatic packing method, comprising the following steps:

[0043] S1. The delivery line delivers the batteries one by one to elevator 1;

[0044] S2. The elevator 1 receives two consecutive batteries from the material delivery line to form a battery pack, and transports the battery pack to the batching warehouse 2;

[0045] S3. The two layers of batching conveying devices 22 in the batching warehouse 2 receive and convey the battery packs from the elevator 1, and then deliver the batteries in the battery packs to the installation station 3 one by one; when one layer of batching conveying device 22 receives the battery pack from the elevator 1, the other layer of batching conveying device 22 delivers the battery pack to the installation station 3;

[0046] S4. When the installation station 3 receives batteries from the batching warehouse 2, it receives only one battery at a time and delivers the battery into the container.

[0047] Through the above structure and method, the delivery line, elevator 1 and batching warehouse 2 in the present invention can leave beat space for the subsequent process, reduce the waiting time of the subsequent process, avoid the ineffective action of the installation station 3, so that the installation station 3 can operate efficiently and the battery filling efficiency can be greatly improved. The specific structure of the three parts of the elevator 1, batching warehouse 2 and installation station 3 is as follows.

[0048] like Figure 2 As shown, the lift 1 includes a lifting frame 11, a lifting drive device 12 and a lifting conveying frame 13. The lifting drive device 12 and the lifting conveying frame 13 are both arranged on the lifting frame 11. The lifting drive device 12 drives the lifting conveying frame 13 to move up and down. The lifting frame 11 includes a lifting top frame 111 and two lifting side frames 112 arranged at both ends of the lifting top frame 111. The two lifting side frames 112 are parallel to each other and perpendicular to the lifting top frame 111 and the ground; the lifting conveying frame 13 is arranged inside the frame of the lifting frame 11, and the side edges thereof are slidably matched with the lifting side frames 112.

[0049] The lifting drive device 12 includes a lifting motor 121, a lifting reducer 122 and a lifting sprocket 123. The output end of the lifting motor 121 is fixedly connected to the input end of the lifting reducer 122. The lifting reducer 122 is fixed to the middle of the lifting top frame 111. There are two groups of lifting sprockets 123, which are respectively arranged along the two lifting side frames 112. It is more stable to use bilateral drive during the lifting process, so the lifting reducer 122 extends two output shafts to connect the two groups of lifting sprockets 123 respectively, and drives the two groups of lifting sprockets 123 synchronously. The lifting conveying frame 13 is extended with a connecting plate 132. The lifting conveying frame 13 is fixedly arranged on the chain of the lifting sprocket 123 through the connecting plate 132, and the connecting plate 132 has a mechanical anti-falling structure. The opposite sides of the two lifting side frames 112 are both provided with lifting rails 113, and the lifting rails 113 are rectangular rails; the lifting conveying frame 13 is provided with a lifting guide wheel 131 that cooperates with the lifting rail 113, and the lifting guide wheel 131 is a cam follower. Compared with the linear guide rail, the cooperation between the rectangular rail and the cam follower can better accommodate installation errors and improve service life while ensuring the guiding accuracy. At the same time, in conjunction with the above-mentioned lifting drive device 12, a bilateral driving structure is realized, so that the lifting conveyor frame 13 can be lifted and lowered smoothly.

[0050] Two parallel layers of battery racks 4 are arranged inside the frame of the lifting and conveying rack 13. Each layer of battery racks 4 receives batteries delivered from the material delivery line in turn at a high place. After receiving the batteries, two batteries form a battery pack. The lifting and driving device 12 delivers the battery pack. After reaching the position, each layer of battery racks 4 synchronously delivers the batteries to the batching warehouse 2. That is, when the elevator 1 receives batteries from the material delivery line, it can receive two batteries continuously and transport two batteries to the batching warehouse 2 at one time, thereby improving the delivery efficiency.

[0051] like Figure 3 The batching warehouse 2 shown also includes a batching frame 21, and the batching conveying devices 22 are parallel to each other and are both arranged on the batching frame 21. The batching conveying device 22 includes a batching conveying frame 23 and a batching driving device 24, and the batching driving device 24 drives the batching conveying frame 23 to move horizontally.

[0052] On the two opposite sides of the batching conveying frame 23, one side is provided with a batching driving device 24, and the other side is slidably matched with the batching frame body 21. The batching driving device 24 includes a batching motor, a batching reducer and a batching gear arranged on the batching conveying frame 23, and a batching rack 241 arranged on the batching frame body 21, and the batching rack 241 is arranged along the movement direction of the batching conveying frame 23. The batching motor, the batching reducer and the batching gear are not shown in the figure, and the output end of the batching motor is fixedly connected to the input end of the batching reducer, and the output shaft of the batching reducer is fixedly connected to the batching gear, and the batching gear and the batching rack 241 cooperate with each other. Figure 4 The figure shows a batching driving device 24, on which a batching slider 231 and a batching slide rail 211 cooperating with the batching slider 231 are also provided. The batching slider 231 is fixed to the batching conveying frame 23, and the batching slide rail 211 is provided on the batching frame 21 and is parallel to the batching rack 241. Figure 5 As shown, a batching guide wheel 232 and a batching track 212 matching the batching guide wheel 232 are provided on the side opposite to the batching driving device 24. The batching guide wheel 232 is a cam follower, which is provided on one side of the batching conveying frame 23. The batching track 212 is a rectangular track, which is provided on one side of the batching frame 21. The batching track 212 is parallel to the batching rack 241. Compared with the linear guide rail, the mutual cooperation of the rectangular track and the cam follower can better accommodate the installation error and improve the service life while ensuring the guiding accuracy. Therefore, in conjunction with the sliding structure on both sides, the batching conveying device 22 can realize the bilateral synchronous drive and smooth transportation of the batching conveying frame 23, and prevent the tilting during the horizontal movement, which causes the battery to deflect when feeding and discharging.

[0053] Two layers of parallel battery racks 4 are arranged inside the frame of the batching conveyor rack 23. The two layers of battery racks 4 synchronously receive the batteries in the battery pack from the elevator 1, and after receiving, they are conveyed by the batching driving device 24. After reaching the position, the two layers of battery racks 4 sequentially deliver their respective batteries to the installation station 3. In this way, the batching warehouse 2 can store four batteries at the same time, and when the batching conveyor device 22 of one layer receives the battery pack from the elevator 1, the other layer can deliver its own battery pack and deliver it to the installation station 3 piece by piece, which greatly saves the conveying time and reduces the unnecessary waiting time during the conveying process.

[0054] The elevator 1 and the batching warehouse 2 use the same battery rack 4, which can transport batteries without damaging them. After the batteries enter the battery rack 4, there are protective measures all around to prevent the batteries from deflecting or sliding out of the battery rack 4 when the battery rack 4 is transported. Figure 6 As shown, the structure of the battery rack 4 is specifically described using the structure of the battery rack 4 in the elevator 1: the battery rack 4 includes a first frame body 41 and a first transmission group 43 arranged on the first frame body 41, and the first frame body 41 of the battery rack 4 is fixed to the lifting conveyor frame 13; in the batching warehouse 2, the first frame body 41 of the battery rack 4 is fixed to the batching conveyor frame 23.

[0055] Two first attached plate chains 42 are respectively arranged on the left and right opposite sides of the first frame 41. The first transmission group 43 synchronously drives the two first attached plate chains 42. The first attached plate chains 42 are rubber attached plate chains, which directly contact the bottom surface of the battery and transport the battery. A rubber-coated roller group 45 is arranged on the outer side of each first attached plate chain 42, and the rubber-coated roller group 45 guides and protects the battery.

[0056] The first transmission group 43 is fixed on the first frame 41, and includes a first motor 431, a first reducer 432, a first transmission sprocket 433 and a first transmission shaft 434. The output end of the first motor 431 is fixedly connected to the input end of the first reducer 432. The output shaft of the first reducer 432 transmits power to the first transmission shaft 434 through the first transmission sprocket 433. The two ends of the first transmission shaft 434 are respectively fixedly connected to the power wheels that can drive the first attached plate chain 42 to move, so that the first transmission group 43 drives the first attached plate chain 42 to move. In this way, the transmission error can be further reduced, and the battery rack 4 adopts bilateral synchronous driving of the first attached plate chain 42, which can prevent the battery rack 4 from deflecting when the battery is fed in and out.

[0057] The first limiting device 44 is provided on both the front and rear opposite sides of the first frame 41. The first limiting device 44 includes a first limiting cylinder 441, a first limiting shaft 442 and a first limiting block 443. The first limiting block 443 takes the first limiting shaft 442 as the rotation center and is connected to the first limiting shaft 442 through a reset device. The first limiting block 443 has a first blocking portion 443a and a first force-bearing portion 443b. A rubber block is provided on the side of the first blocking portion 443a facing the battery. The first force-bearing portion 443b is controlled by the first limiting cylinder 441 to rotate the first limiting block 443 to open and close the first blocking portion 443a. This can prevent the battery on the battery rack 4 from sliding out of the first attached plate chain 42 when the system fails or the transportation is unexpected.

[0058] like Figure 7 or Figure 8 As shown, the installation station 3 includes an X-axis conveyor 31, a Z-axis conveyor 32 and a Y-axis conveyor 33. The X-axis conveyor 31 drives the battery to move in the X-axis direction, the Z-axis conveyor 32 drives the battery to move in the Z-axis direction, and the Y-axis conveyor 33 drives the battery to move in the Y-axis direction. A plurality of battery racks are arranged inside the container, and the Y-axis conveyor 33 receives one battery at a time from the batching warehouse 2 and delivers the battery to the battery rack. The installation station 3 uses three-axis linkage to convey batteries, which can accurately locate and deliver batteries into the rack. Its specific structure is as follows:

[0059] like Fig. 9 As shown, the X-axis conveying device 31 includes an X-axis base 311, an X-axis slide 312 and an X-axis driving device 313. The X-axis slide 312 and the X-axis driving device 313 are both arranged on the X-axis base 311. The X-axis base 311 is arranged along the length direction of the container body. The X-axis driving device 313 includes an X-axis motor 3131, an X-axis reducer 3132, an X-axis gear 3133 and an X-axis rack 3134. The output end of the X-axis motor 3131 is fixedly connected to the input end of the X-axis reducer 3132, and the output shaft of the X-axis reducer 3132 is fixedly connected to the X-axis gear 3133. The X-axis gear 3133 is a helical gear. The X-axis rack 3134 is arranged on one side of the X-axis base 311, and is also arranged along the length direction of the container body, and can be meshed with the X-axis gear 3133. At the same time, this group of helical gear racks has a backlash elimination mechanism and automatic lubrication. Thereby, the X-axis driving device 313 drives the X-axis slide 312 to move along the X-axis rack 3134, that is, the X-axis conveying device 31 can realize the horizontal movement of the X-axis slide 312 along the X-axis base 311 through the above structure, that is, the battery is conveyed in the X-axis direction.

[0060] The X-axis slide 312 is provided with a Z-axis conveying device 32, such as Fig.10As shown, the Z-axis conveying device 32 includes a Z-axis main frame 321, a Z-axis support frame 322 and a Z-axis driving device 323. The Z-axis main frame 321 is fixed to the X-axis slide 312, and the Z-axis support frame 322 and the Z-axis driving device 323 are both arranged on the Z-axis main frame 321. The Z-axis main frame 321 includes a Z-axis top frame 3211 and two Z-axis side frames 3212 arranged at both ends of the Z-axis top frame 3211. The two Z-axis side frames 3212 are parallel to each other, arranged along the height direction of the container body and perpendicular to the Z-axis top frame 3211, and the Z-axis support frame 322 is arranged inside the frame of the Z-axis main frame 321. Two groups of symmetrical Z-axis driving devices 323 are arranged on the Z-axis main frame 321, and each Z-axis side frame 3212 is arranged with a group of Z-axis driving devices 323. The Z-axis driving device 323 drives the Z-axis support frame 322 to move up and down. The Z-axis driving device 323 includes a Z-axis motor 3231 disposed on the top of the Z-axis side frame 3212, a Z-axis screw rod 3232 fixedly connected to the output end of the Z-axis motor 3231, and a Z-axis slider 3233 threadedly connected to the Z-axis screw rod 3232. The Z-axis screw rod 3232 is disposed along the Z-axis side frame 3212. The Z-axis motor 3231 drives the Z-axis slider 3233 to move up and down through the Z-axis screw rod 3232. The Z-axis slider 3233 is slidably matched with the Z-axis side frame 3212. The opposite sides of the two Z-axis sliders 3233 are respectively provided with a first connecting seat 3234 and a second connecting seat 3235. Fig.11 As shown, combined with Figure 8 , the first connecting seat 3234 and one side of the Z-axis support frame 322 are directly hinged; Fig.12 As shown, combined with Figure 8 , the second connecting seat 3235 and the other side of the Z-axis support frame 322 are connected by a connecting rod 3236, and the two ends of the connecting rod 3236 are respectively hinged to the Z-axis drive device 323 and the Z-axis support frame 322. In the initial state, the Z-axis support frame 322 is in a horizontal position. The above structure specifically realizes the transportation of batteries in the Z-axis direction, and at the same time realizes the angle compensation mechanism: through the Z-axis drive device 323 on both sides that can be asynchronous, the Z-axis support frame 322 is tilted in the Z-axis direction, which makes up for the defect that the container is tilted during transportation and cannot be properly packed.

[0061] The Z-axis support frame 322 is fixed with a Y-axis conveying device 33, such as Fig.13As shown, the Y-axis conveying device 33 includes a second frame 331 and a second transmission group 333 arranged on the second frame 331. Two second attached plate chains 332 are respectively arranged on the left and right opposite sides of the second frame 331. The second transmission group 333 synchronously drives the two second attached plate chains 332. The second attached plate chains 332 are rubber attached plate chains, which are in direct contact with the bottom surface of the battery and convey the battery. A side guide roller 336 is arranged on the outer side of each second attached plate chain 332. The surface of the side guide roller 336 is made of polyurethane or nylon material, so as to guide and protect the battery.

[0062] like Fig.14 As shown, combined with Fig.13 The second transmission group 333 is fixed on the second frame 331, and includes a second motor 3331, a second reducer 3332, a second transmission sprocket 3333 and a second transmission shaft 3334. The output end of the second motor 3331 is fixedly connected to the input end of the second reducer 3332. The output shaft of the second reducer 3332 transmits power to the second transmission shaft 3334 through the second transmission sprocket 3333. The two ends of the second transmission shaft 3334 are respectively fixedly connected to the power wheels that can drive the second attached plate chain 332 to move, so that the second transmission group 333 drives the second attached plate chain 332 to move. In this way, the transmission error can be further reduced, and the Y-axis conveying device 33 adopts bilateral synchronous driving of the second attached plate chain 332 to prevent the battery from deflecting when feeding and discharging.

[0063] The second frame 331 is further provided with second limiting devices 334 on the front and rear opposite sides. Fig.15 As shown, combined with Fig.13 The second limiting device 334 includes a second limiting cylinder 3341, a second limiting shaft 3342 and a second limiting block 3343. The second limiting block 3343 takes the second limiting shaft 3342 as the rotation center and is connected to the second limiting shaft 3342 through a reset device; the second limiting block 3343 has a second blocking portion 3343a and a second force-bearing portion 3343b. The second blocking portion 3343a is provided with a rubber block on the side facing the battery. The second force-bearing portion 3343b is controlled by the second limiting cylinder 3341, so that the second limiting block 3343 rotates to realize the opening and closing of the second blocking portion 3343a. In this way, the battery can be prevented from sliding out of the second attached plate chain 332 when the system fails or the conveying is unexpected. In this way, the Y-axis conveying device 33 can convey the battery without damaging the battery, and after the battery enters the Y-axis conveying device 33, there are protective measures all around to prevent the battery from deflecting or sliding out of the Y-axis conveying device 33 when conveying the Y-axis conveying device 33.

[0064] The Y-axis conveying device 33 also includes a correction mechanism, which includes two cameras 337 arranged on the second frame 331 and two detection holes arranged on the battery placement rack. The cameras 337 are located at the conveying end. Before the Y-axis conveying device 33 is conveyed, the two cameras 337 shoot the detection holes of the current corresponding battery placement rack, and the visual processing module analyzes the positions of the two detection holes to obtain the angle value, which is then compared with the reference value pre-set in the processing module. The reference value is the data when the two detection holes are in a horizontal position. When the two are inconsistent, the difference data between the two is transmitted back to the controller, and the controller issues a command to control the X-axis drive device 313 and the Z-axis drive device 323, so as to adjust the horizontal height, vertical height and tilt angle of the Y-axis conveying device 33. Through the above structure, the tilt angle of the container can be detected, and the correction mechanism and the Z-axis conveying device 32 can achieve fine-tuning accuracy and avoid creeping.

[0065] The Y-axis conveying device 33 further includes two sets of pushing mechanisms 338 disposed on the second frame 331, such as Fig.16 As shown, combined with Fig.13 , two groups of pushing mechanisms 338 are respectively arranged on the same side of the second attached plate chain 332, and the pushing mechanism 338 includes a pushing drive device and a pushing execution device; the pushing drive device includes a pushing motor 3381 arranged on the second frame 331, a pushing screw rod 3382 fixedly connected to the output end of the pushing motor 3381, and a pushing slider 3383 threadedly connected to the pushing screw rod 3382; the pushing execution device includes a pushing base 3384, a pushing rod 3385 and a pushing cylinder 3386, the head of the pushing rod 3385 is fixedly connected with a pushing head 3387 of soft material, and the tail is hinged to the pushing base 3384, the output end of the pushing cylinder 3386 is connected to the pushing rod 3385, and the connection is close to the tail of the pushing rod 3385; the pushing base 3384 is fixedly connected to the pushing slider 3383 through a pressure sensor 3388. The pushing mechanism 338 adopts the bilateral symmetrical layout as above, which can realize position and torque control. At the same time, the pressure sensor 3388 is used for thrust protection and determines whether it is in place. The pressure sensor 3388 is parallel to the thrust axis to ensure the service life. After the Y-axis conveying device 33 is conveyed for a distance via the second attached plate chain 332, the battery cannot be completely delivered to the battery rack due to friction and other reasons. At this time, the pushing mechanism 338 is required to push the battery further into the battery rack. The pushing mechanism 338 can be set with a maximum pushing force. When the maximum pushing force is reached, the system stops pushing and alarms to remind the operator to check the installation of the battery.

[0066] The batteries transported by the above-mentioned automatic packing system are generally divided into long batteries and short batteries. The sizes of the two batteries are different. In order to reasonably load the two batteries into the container, the above-mentioned system can adopt two different sizes, corresponding to long batteries and short batteries respectively, and at the same time ensure that the packing system of long batteries must be compatible with short batteries, that is, it is necessary to ensure that short batteries can be normally transported in the packing system of long batteries.

[0067] In actual application, an automatic packing system for long batteries and an automatic packing system for short batteries are respectively provided on opposite sides of the container. When loading long batteries, since the size of the long batteries just matches the size of the battery placement box, in order to prevent loading errors, they are usually loaded from only one side of the container, that is, the automatic packing system for long batteries is used. When loading short batteries, since the length of the short batteries is exactly half the length of the battery placement box, in order to improve loading efficiency, they are usually loaded from both sides of the container at the same time, that is, the automatic packing system for long batteries and the automatic packing system for short batteries are put into use at the same time; the two systems do not affect each other, not only can the efficiency be doubled on the original basis, but also when one of the systems fails, the other can continue to work and complete all the short battery loading.

[0068] In summary, the present invention, from the material delivery line, the elevator 1 to the batching warehouse 2, all parts leave beat space for the subsequent process, reduce the waiting time of the subsequent process, avoid the ineffective action of the installation station 3, so that the installation station 3 can operate efficiently, and the battery filling efficiency can be greatly improved. In addition, a variety of battery protection devices and different driving modes are set in the system to adapt to the functions required to be realized by each device, making the system more flexible and safe.

[0069] The above is only one embodiment of the present invention. It should be pointed out that a person skilled in the art can make several similar modifications and improvements without departing from the creative concept of the present invention, and these should also be regarded as within the scope of protection of the present invention.
