[0013] In some embodiments, a first cartridge blocking mechanism and a second cartridge blocking mechanism are respectively provided at both ends of the first cartridge stacking rack, and the first cartridge blocking mechanism and the second cartridge blocking mechanism are configured to block or release the cartridge located at the bottom of the first cartridge stacking rack from both ends.

[0014] By arranging the material box blocking mechanisms at both ends of the first material box stacking rack, the material boxes in the first material box stacking rack are blocked and released.

[0015] In some embodiments, two material box blocking devices are further provided between the feeding end and the unloading end of the material box transfer part. The two material box blocking devices are used to prevent the material box located at the feeding end of the material box transfer part from moving when there is a material box at the unloading end of the material box transfer part.

[0016] By arranging a material box blocking device between the feeding end and the unloading end of the material box transfer part, the material box on the feeding end of the material box transfer part is blocked, ensuring that there is only one material box at the unloading end of the material box transfer part.

[0017] In some embodiments, the empty material box stacking mechanism includes a first stacking rack lifting part, a second material box stacking rack and a first stacking conveying part, wherein: the second material box stacking rack is connected to the driving end of the first stacking rack lifting part, and a plurality of first material box receiving slots are arranged in the second material box stacking rack along the vertical direction.

[0022] Through the cooperation of the second box-taking part and the material box carrying plate, the empty material boxes on the conveying mechanism are automatically transferred to the material receiving mechanism to complete the collection of unqualified battery strings or qualified battery strings after repair, and the full material boxes filled with qualified battery strings are automatically transferred from the material receiving mechanism to the conveying mechanism; the material box carrying plates are arranged layer by layer in the rack, and by controlling the material box carrying plates to extend to receive the materials and retract after receiving the materials, the reception of different battery strings does not interfere with each other, and different battery strings can be received into the rack, effectively saving the space occupied by the equipment.

[0023] In some embodiments, the second box-taking part includes two material box lifting assemblies, which are respectively arranged at the front and rear tracks of the conveying mechanism, and the frame is arranged on the side of the conveying mechanism. The material box lifting assembly is used to lift the empty material box on the conveying mechanism upward, and lower the empty material box onto the material box supporting plate when the material box supporting plate is extended; the material box lifting assembly is also used to lift the full material box filled with qualified battery strings on the material box supporting plate when the material box supporting plate is extended, and lower the full material box filled with qualified battery strings onto the conveying mechanism when the material box supporting plate is retracted.

[0024] A second box taking part with a simple structure is provided, which realizes the transfer of the material box between the conveying mechanism and the material receiving mechanism through the cooperation of two material box lifting components.

[0025] In some embodiments, at least two translation mechanisms are also installed on the frame. The translation mechanisms are arranged in a one-to-one correspondence with the material box supporting plates. The material box supporting plates are connected to the movable parts of the translation mechanisms.

[0051] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] The existing battery string repair system cannot achieve automatic circulation of the material box, so manual loading and unloading of the material box is required frequently, which affects the repair rhythm and efficiency of the battery string.

[0053] In view of this, the present invention provides a battery string material box circulation device, which realizes the automatic circulation and circulation of material boxes between various workstations, greatly improving the battery string rework efficiency.

[0054] like Figures 1 to 2 As shown, the battery string box circulation device provided by the present invention includes a battery string feeding mechanism 1, an empty box stacking mechanism 2, a battery string receiving mechanism 3 and a full box stacking mechanism 4, wherein:

[0055] The battery string loading mechanism 1 is used to supply magazines containing battery strings to be repaired and to transport empty magazines to the empty magazine stacking mechanism 2. The empty magazine stacking mechanism 2 is also used to transport empty magazines to the battery string receiving mechanism 3. The battery string receiving mechanism 3 can accommodate at least two empty magazines. After repair, unqualified and qualified battery strings are collected into different empty magazines located on the battery string receiving mechanism. The battery string receiving mechanism 3 is also used to transport full magazines filled with qualified battery strings to the full magazine stacking mechanism 4.

[0056] The working process of the battery string box circulation device provided by the present invention is as follows:

[0057] The battery string loading mechanism 1 transports the material box containing the battery string to be repaired to the battery string to be repaired material taking station located thereon.

[0058] When all the battery strings to be repaired in the material box at the battery string to be repaired material taking station are taken out, the battery string loading mechanism 1 then transports the emptied empty material box backward to the empty material box stacking mechanism 2 for stacking and storage.

[0059] The empty material box stacking mechanism 2 conveys at least two empty material boxes to the battery string receiving mechanism 3 .

[0060] After repair, the unqualified and qualified battery strings are collected into different empty boxes on the battery string collecting mechanism 3. The full boxes filled with unqualified battery strings are directly removed from the battery string collecting mechanism 3, while the full boxes filled with qualified battery strings are transported by the battery string collecting mechanism 3 and stacked into the full box stacking mechanism 4.

[0061] It can be seen that the battery string box circulation device provided by the present invention realizes the automatic circulation and circulation of the box between each workstation. During the repair process, it is only necessary to regularly remove the boxes filled with unqualified battery strings and qualified battery strings from the battery string receiving mechanism 3 and the full box stacking mechanism 4, and regularly replenish the boxes filled with battery strings to be repaired to the battery string loading mechanism 1, without the need for manual frequent loading and unloading of the boxes. The present invention greatly improves the efficiency of battery string repair.

[0062] Optional, such as Figures 3 to 5As shown, the battery string loading mechanism 1 includes a first material box stacking rack 11, a first box taking section 12, a material box transfer section 13, and a lifting and conveying section 14, wherein: the feeding end of the material box transfer section 13 is located below the first material box stacking rack 11, and the unloading end of the material box transfer section 13 is located above the lifting and conveying section 14. The material boxes containing the battery strings to be repaired are stacked in the first material box stacking rack 11. The first box taking section 12 is used to pick up the material box located at the bottom of the first material box stacking rack 11 and place the picked up material box on the material box transfer section 13. The material box transfer section 13 is used to transfer the material boxes at the feeding end of the material box transfer section 13 to the unloading end of the material box transfer section 13. The battery strings to be repaired in the material boxes are emptied at the unloading end of the material box transfer section. The lifting and conveying section 14 is used to lift the empty material boxes located at the unloading end of the material box transfer section 13 upwards and convey the empty material boxes to the empty material box stacking mechanism 2.

[0063] It can be seen that through the cooperation of the first material box stacking rack 11, the first box taking part 12, the material box transfer part 13 and the lifting and conveying part 14, the battery string loading mechanism 1 realizes the automatic loading of the material box containing the battery string to be repaired, and after completing the emptying of the material box, the empty material box is provided to the empty material box stacking mechanism.

[0064] Optionally, a first cartridge blocking mechanism 15 and a second cartridge blocking mechanism are respectively provided at both ends of the first cartridge stacking rack 11. In the initial state, the first cartridge blocking mechanism 15 and the second cartridge blocking mechanism block the cartridge located at the bottom of the first cartridge stacking rack 11 from both ends. In this way, the cartridges stacked in the first cartridge stacking rack 11 are blocked and positioned in the first cartridge stacking rack 11.

[0065] When it is necessary to take out a material box, the first material box blocking mechanism 15 and the second material box blocking mechanism release the material box located at the bottom of the first material box stacking rack 11, and the material box falls from the bottom opening of the first material box stacking rack 11 under the action of its own gravity and falls onto the first box taking part 12. The first box taking part 12 places the material box on the feeding end of the material box transfer part 13. At the same time, the first material box blocking mechanism 15 and the second material box blocking mechanism reset and block the material box currently located at the bottom of the first material box stacking rack 11 from both ends, thereby ensuring that the first box taking part 12 can take out one material box from the first material box stacking rack 11 each time.

[0066] Optionally, the first material box blocking mechanism 15 and the second material box blocking mechanism have the same structure. Taking the first material box blocking mechanism 15 as an example, it includes a material box blocking plate and a blocking plate driving device. The blocking plate driving device is installed on the first material box stacking rack 11, and the material box blocking plate is connected to the driving end of the baffle driving device. The blocking plate driving device is used to drive the material box blocking plate to move toward or away from the material box.

[0067] When the blocking plate driving device drives the magazine blocking plate to move toward the magazine to the first predetermined position, the magazine blocking plate supports the bottom surface of the magazine at the bottom of the first magazine stacking rack 11, thereby blocking the magazine at the bottom of the first magazine stacking rack 11.

[0068] When the blocking plate driving device drives the magazine blocking plate to move away from the magazine to the second predetermined position, the magazine blocking plate is separated from the bottom surface of the magazine located at the bottom of the first magazine stacking rack 11, thereby releasing the magazine located at the bottom of the first magazine stacking rack 11.

[0069] Optionally, two material box blocking devices 16 are further provided between the feeding end and the unloading end of the material box transfer section 13. The two material box blocking devices 16 are used to prevent the material box located at the feeding end of the material box transfer section 13 from moving when there is a material box at the unloading end of the material box transfer section 13. In the initial state, the movable portion of the material box blocking device 16 is located below the material box transfer section 13, and the material box transfer section 13 can smoothly transfer the material box at the feeding end of the material box transfer section 13 to the unloading end of the material box transfer section 13. When there is already a material box at the unloading end of the material box transfer section 13, the movable portion of the material box blocking device 16 extends upward from the material box transfer section 13, thereby preventing another material box located at the feeding end of the material box transfer section 13 from moving to the unloading end of the material box transfer section 13, causing a material box collision.

[0070] Optionally, the cartridge blocking device 16 may use a pneumatic cylinder.

[0071] Optionally, a photoelectric sensor is also provided in the first material box stacking rack 11. When the number of material boxes in the first material box stacking rack 11 is less than a predetermined number, the photoelectric sensor generates an induction signal to prompt manual replenishment of the material box containing the battery string to be repaired onto the battery string loading mechanism 1.

[0072] Optional, such as Figures 6 and 7 As shown, the empty box stacking mechanism 2 includes a first stacking rack lifting unit 21, a second box stacking rack 22, and a first stacking conveyor unit 23, wherein the second box stacking rack 22 is connected to the driving end of the first stacking rack lifting unit 21, and a plurality of first box receiving slots 24 are vertically arranged in the second box stacking rack 22. The first stacking rack lifting unit 21 is used to drive the second box stacking rack 22 to rise and fall, so that each first box receiving slot 24 is sequentially docked with the battery string feeding mechanism 1. The first stacking conveyor unit 23 is located in the second box stacking rack 22. The first stacking conveyor unit 23 is used to sequentially convey the empty boxes output by the battery string feeding mechanism 1 to each first box receiving slot 24, and to sequentially convey the empty boxes located in each first box receiving slot 24 to the battery string receiving mechanism 3.

[0073] Through the cooperation of the first stacking rack lifting part 21 and the first stacking conveying part 23 , the empty boxes are automatically stacked into the second box stacking rack 22 , and the empty boxes in the second box stacking rack 22 are conveyed to the battery string receiving mechanism 3 .

[0074] When the second material box stacking rack 22 is full, the system prompts manual material removal. After the manual material box is removed, the first stacking rack lifting unit 21 drives the second material box stacking rack 22 to return to its original position to receive new material boxes.

[0075] When the manual material box is not fully taken away, optional, such as Figures 6 and 7 As shown, the empty material box stacking mechanism 2 also includes a photoelectric sensor 25 arranged on the side of the second material box stacking rack 22. The photoelectric sensor 25 is used to detect whether there is an empty material box in each first material box receiving slot 24 layer by layer when the material box is manually taken away and the first stacking rack lifting part 21 drives the second material box stacking rack 22 to return to its position, and controls the first stacking rack lifting part 21 to stop driving when an empty material box is detected, so that the first material box receiving slot 24 adjacent to the first material box receiving slot 24 where the detected empty material box is located and where no empty material box exists is docked with the battery string loading mechanism 1 for subsequent empty material box reception.

[0076] Taking the second magazine stacking rack 22 receiving an empty magazine during its ascent as an example, Figure 6 The five layers of first material box receiving slots 24 on the second material box stacking rack 22 are named as the 1st layer, the 2nd layer, the 3rd layer, the 4th layer and the 5th layer from top to bottom. After the first stacking rack lifting part 21 drives the second material box stacking rack 22 to rise 5 times, the system prompts that the second material box stacking rack 22 is full. The empty material boxes are manually taken away from the 5th layer. Taking the removal of 3 empty material boxes as an example, after taking them away, the first stacking rack lifting part 21 drives the second material box stacking rack 22 to descend layer by layer. Each time it descends, the photoelectric sensor 25 detects whether there is an empty material box on that layer. If there is no empty material box, it continues to descend until the 2nd layer is detected. If an empty material box is detected, the second material box stacking rack 22 stops descending. At this time, the 3rd layer is docked with the battery string loading mechanism 1, and the battery string loading mechanism 1 can transport the empty material box into the 3rd layer stack. Then the first stacking rack lifting part 21 drives the second material box stacking rack 22 to rise, and the 4th layer is ready to receive the empty material box. When the battery string receiving mechanism 3 needs an empty box, the second box stacking rack 22 moves down one level to deliver the empty box on the third level. At this time, the third level is ready to receive the empty box delivered by the battery string feeding mechanism 1 .

[0077] Optional, such as Figures 8 and 9As shown, the battery string receiving mechanism 3 includes a conveying mechanism 31 and a receiving mechanism 32 arranged on the side of the conveying mechanism 31, wherein: the two ends of the conveying mechanism 31 are respectively connected to the empty box stacking mechanism 2 and the full box stacking mechanism 4, and the conveying mechanism 31 is used to receive the empty boxes conveyed by the empty box stacking mechanism 2. The receiving mechanism 32 is used to obtain empty boxes from the conveying mechanism 31. The unqualified battery strings and qualified battery strings after repair are respectively received into different empty boxes located on the receiving mechanism 32. The receiving mechanism 32 is also used to place the full boxes filled with qualified battery strings back onto the conveying mechanism 31. The conveying mechanism 31 is also used to convey the full boxes filled with qualified battery strings to the full box stacking mechanism 4.

[0078] The receiving process of the battery string receiving mechanism 3 is as follows:

[0079] The conveying mechanism 31 receives the empty material boxes output by the empty material box stacking mechanism 2 .

[0080] The material receiving mechanism 32 obtains at least two empty material boxes from the conveying mechanism 31 .

[0081] After repair, the unqualified and qualified battery strings are collected into different empty boxes on the receiving mechanism 32. The full boxes filled with unqualified battery strings are directly removed from the receiving mechanism 32, while the full boxes filled with qualified battery strings are returned to the conveying mechanism 31 by the receiving mechanism 32.

[0082] The conveying mechanism 31 conveys and stacks the full boxes filled with qualified battery strings into the full box stacking mechanism 4 .

[0083] It can be seen that through the cooperation of the conveying mechanism 31 and the receiving mechanism 32, the battery string receiving mechanism automatically receives the empty material boxes output by the empty material box stacking mechanism, and can automatically convey the full material boxes filled with qualified battery strings to the full material box stacking mechanism, thereby greatly improving the receiving efficiency of the repaired battery strings.

[0084] Optional, such as Figures 10 to 15 As shown, the receiving mechanism 32 includes a second box-taking section, a frame 321, and at least two box-carrying plates 322 arranged layer by layer on the frame 321. Each box-carrying plate 322 can extend independently from the frame 321 to receive empty boxes removed from the conveying mechanism 31 by the second box-taking section, as well as to receive defective or qualified battery strings after repair. After receiving an empty box, defective or qualified battery string after repair, the plate is returned to the frame 321. The second box-taking section is also used to remove a full box filled with qualified battery strings from the corresponding box-carrying plate 322 and place it back on the conveying mechanism 31.

[0085] Figures 10 to 15In the embodiment, three material box carrying plates 322 are correspondingly provided on the frame 321 of the material receiving mechanism 32. Optionally, the material receiving process of the material receiving mechanism 32 is as follows:

[0086] Before receiving the material, the three material box carrying plates 322 extend out of the frame 321 in sequence to receive the empty material boxes supplied by the second box taking part. After obtaining the empty material boxes, the material box carrying plates 322 return to the frame 321.

[0087] Start the material receiving process, specifically:

[0088] The transport device transports the repaired battery strings one by one from the repair platform to the top of the receiving mechanism 32 .

[0089] According to the type of the currently arriving battery string, the corresponding material box carrying plate 322 is controlled to extend out of the frame 321 to implement the collection of the current battery string.

[0090] After completing the collection of the current battery string, make the following choices based on the current status of the material box:

[0091] Case 1: The material box is full of battery strings. The following steps are performed according to the type of battery strings:

[0092] If the battery string is unqualified, the full box is removed directly from the box carrier plate 322 to complete the unqualified battery string unloading. The second box removal unit replenishes the empty box onto the box carrier plate 322, and the box carrier plate 322 then returns to the rack 321 to wait for the next battery string of the corresponding type.

[0093] If the battery string is qualified, the second box-taking unit transfers the full box to the conveying mechanism 31, which then stacks the full box into the full box stacking mechanism 4. The second box-taking unit replenishes the empty box onto the box carrier 322, which then returns to the rack 321 to wait for the next battery string of the corresponding type.

[0094] Case 2: If the material box is not yet full of battery strings, the material box carrying plate 322 is controlled to return to the rack 321 to wait for the next battery string of the corresponding type to be received.

[0095] Of course, the material box carrier plate can also return to the rack after receiving the battery string, and then judge the current status of the material box.

[0096] Optionally, the qualified battery strings after repair are subdivided into the first category qualified battery strings and the second category qualified battery strings according to predetermined standards. At this time, the material boxes carried on the three material box carrier plates 322 respectively implement the collection of the first category qualified battery strings, the second category qualified battery strings and the unqualified battery strings.

[0097] Optionally, the empty material boxes for collecting unqualified battery strings are placed on the material box carrying plate 322 on the top layer, so that it is more convenient to take away the full material boxes filled with unqualified battery strings thereon.

[0098] In other embodiments, two, four, or other numbers of material box carrier plates 322 may be provided to implement classified collection of repaired battery strings.

[0099] Optionally, at least two translation mechanisms are installed on the frame 321, and the translation mechanisms are arranged in a one-to-one correspondence with the material box supporting plates 322. The material box supporting plates 322 are connected to the movable parts of the translation mechanisms. The translation mechanisms are used to drive the material box supporting plates 322 to extend or retract into the frame 321.
