Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, and particularly relates to a cartridge splitting detection device. Background Art

[0002] Lithium-ion batteries are currently the most widely used power source. During the production process, the battery cells need to be sorted by grade from 256 trays and stored in 160 cartridges, which has the advantages of accuracy, high efficiency, and convenient transportation. Before storage, the cartridges need to be split one by one and switched to the storage station for stacking the battery cells. During the splitting process, due to defects in the cartridges themselves or equipment abnormalities, etc., the cartridges may not be completely split. Since the existing equipment has no detection device, the equipment will continue to operate, which may cause phenomena such as the collision of the equipment servo system or damage to the battery cells, increasing the equipment repair man-hours by about 40%. Since manual loading of cartridges cannot be cancelled, we propose a cartridge splitting detection device. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a cartridge splitting detection device that detects the cartridges during the cartridge unstacking process to ensure the stable operation of the equipment when the cartridges are completely split.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a cartridge splitting detection device, including an unstacking mechanism and a detection mechanism. The unstacking mechanism includes two symmetrically arranged unstacking members. The area between the two unstacking members is set as the cartridge area, and the cartridge area includes a stacking area above and a separation area below. The unstacking member includes a vertical guide member, an unstacking telescopic member, and a clamping member. The unstacking telescopic member is arranged on the vertical guide member and moves up and down between the stacking area and the separation area along the vertical guide member. The telescopic part of the unstacking telescopic member is provided with a clamping member, and the clamping members of the two unstacking members cooperate to clamp the cartridges in the cartridge area. The detection mechanism includes an upper detection member and a lower detection member. The lower detection member is arranged in the separation area and detects the in-place state of the cartridges. The upper detection member is arranged above the lower detection member and is also in the separation area and detects the separation state of the cartridges. The vertical distance between the upper detection member and the lower detection member is less than the height of the cartridges. During the process of the unstacking mechanism unstacking the cartridges in the cartridge area, the detection mechanism detects the cartridges to ensure that the bottom cartridges are split one by one and there is no adhesion.

[0005] As a preferred solution, the unstacking member includes at least two vertical guide members. Linear bearings are arranged on each vertical guide member, and a slide is arranged on the unstacking telescopic member. The slide is connected to each linear bearing.

[0006] As a preferred solution, the unstacking member further includes a vertical driving member. The moving part of the vertical driving member is connected to the slide, and the vertical driving member drives the slide to move up and down along the vertical guide member.

[0007] As a preferred solution, the clamping member includes a mounting end plate and a top support plate. The mounting end plate is connected to the telescopic portion of the unstacking telescopic member. The top support plate is arranged on the mounting end plate, and a cartridge limiting groove is arranged on the top support plate.

[0008] As a preferred solution, a cartridge cushion layer is arranged on the mounting end plate above the top support plate.

[0009] As a preferred solution, transverse guides are arranged on the sliding table, and the mounting end plate is connected to each transverse guide.

The controller receives the detection signals of the upper detection member and the lower detection member, and is connected to an alarm or a display device, etc., so that the operator can timely understand the detection information.

[0011] As a preferred solution, both the upper detection member and the lower detection member are photoelectric switches. The emitting end and the receiving end of each photoelectric switch are respectively arranged on both sides of the cartridge area.

[0012] As a preferred solution, the controller is connected to each vertical driving member and each clamping telescopic member, and the controller is also connected to an alarm.

[0013] As a preferred solution, cartridge stacking guide plates are arranged in the cartridge area. Each cartridge stacking guide plate cooperates to prevent the cartridges stacked in the cartridge area from tipping over.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0022] A cartridge splitting detection device, as Figures 1-4 shown, includes a unstacking mechanism and a detection mechanism. The unstacking mechanism includes two unstacking members, which are symmetrically arranged. The area between the two unstacking members is set as the cartridge area, and the cartridges are stacked in the cartridge area. The cartridge area includes an upper stacking area and a lower separation area. With the cooperation of the two stacking members, the cartridge 9 is stacked in the stacking area and split in the separation area.

[0023] In some embodiments, in order to ensure that the cartridges 9 can be neatly stacked, a cartridge stacking guide plate 8 is provided in the cartridge area. The cartridge stacking guide plate 8 is a vertically arranged L-shaped plate. When the cartridges are stacked in the cartridge area, the corners of the cartridges are at the inner end face position of the cartridge stacking guide plate 8, and the cartridge stacking guide plate 8 can prevent multiple cartridges stacked layer by layer from tipping over. Further, the cartridge stacking guide plate 8 is provided with two, three or four. When the cartridges are stacked in the cartridge area, each cartridge stacking guide plate 8 is respectively at the corners of the cartridges.

[0024] The unstacking member includes a vertical guide member 1, an unstacking telescopic member 2, and a clamping member 3. The vertical guide member 1 is a guiding structure such as a vertically arranged guiding rod or guiding rail. The unstacking telescopic member 2 is installed on the vertical guide member 1 and can move up and down along the vertical guide member 1. The unstacking telescopic member 2 moves between the stacking area and the separation area. A clamping member 3 is provided at the telescopic part of the unstacking telescopic member 2. The unstacking telescopic member 2 drives the clamping member 3 to move between the clamping position and the standby position. When the clamping members 3 of the two unstacking members are both in the clamping position, the two clamping members 3 are in a position close to each other. The two clamping members 3 cooperate to clamp the cartridge between them, and the two clamping members 3 cooperate to lift the cartridges stacked in the cartridge area. When the clamping members 3 of the two unstacking members are both in the standby position, the two clamping members 3 are in a position far from each other, and the two clamping members 3 are both separated from the cartridges in the cartridge area.

[0025] When using the unstacking mechanism to unstack the cartridges 9 in the cartridge area, first, the two unstacking members cooperate to clamp and lift the cartridges 9 in the cartridge area. The two unstacking telescopic members 2 move to the separation area at the same time. At this time, the lowermost cartridge 9 is in the separation area, the lower part of the second-lowermost cartridge 9 is in the separation area while the upper part is in the stacking area, and the cartridges above are all in the stacking area. Then, the two unstacking members both move from the clamping position to the standby position. The two unstacking telescopic members 2 are lifted along the corresponding vertical guide members 1 to the position of the second-lowermost cartridge. Then, the two unstacking members both move from the standby position to the clamping position. At this time, the two unstacking members cooperate to clamp the second-lowermost cartridge. The two unstacking telescopic members 2 are lifted to the stacking area and lift all the cartridges except the lowermost cartridge to the stacking area. At this time, the lowermost cartridge is split and left in the separation area. After taking it away from the separation area, repeating the above steps can gradually realize the unstacking of multiple cartridges.

[0026] The unstacking member includes at least two vertical guide members 1. The vertical guide members 1 are vertically arranged guiding rods, and linear bearings are provided on each vertical guide member 1. The unstacking telescopic member 2 is preferably a cylinder. The unstacking telescopic member 2 is horizontally arranged and its telescopic part faces the location of the other unstacking member. A slide table 4 is provided on the unstacking telescopic member 2. The slide table 4 is connected to each linear bearing. The slide table 4 is connected to at least two linear bearings to prevent the unstacking telescopic member 2 from rotating and affecting the clamping effect on the cartridge.

[0027] In some embodiments, the unstacking member further includes a vertical driving member. The action part of the vertical driving member is connected to the slide table 4. The vertical driving member drives the slide table 4 to move up and down along the vertical guide member 1, thereby driving the unstacking telescopic member 2 and the clamping member 3 at the telescopic part of the unstacking telescopic member 2 to move up and down. As a specific example, the vertical guide member 1 is arranged on the frame body. The vertical driving member includes a driving motor. The driving motor is installed on the frame body and a synchronous pulley is provided on the rotating shaft of the driving motor. A synchronous pulley is also provided on the frame body. The two synchronous pulleys are connected by a synchronous belt. The slide table 4 is connected to the synchronous belt. The driving motor drives the synchronous belt to rotate, thereby driving the slide table 4 to move up and down along the vertical guide member 1.

[0028] As a specific example of the clamping member 3, the clamping member 3 includes a mounting end plate and a top supporting end plate. The mounting end plate is connected to the telescopic portion of the unstacking telescopic member 2. The plate surface of the mounting end plate is vertical, and the top supporting plate is vertically arranged on the mounting end plate. The top supporting plate and the mounting end plate form an L-shaped plate. When the two clamping members 3 cooperate to clamp the cartridge, the top supporting plate is located below the outer edge of the cartridge, and the cartridge and the cartridge above it are both supported on the two top supporting plates.

[0029] The top supporting plate is provided with cartridge limiting grooves corresponding to the limiting edges of the cartridge. The cartridge limiting grooves cooperate with the limiting edges of the cartridge to improve the clamping effect on the cartridge.

[0030] In some embodiments, a cartridge cushion layer is provided on the mounting end plate above the top supporting plate. When the two clamping members 3 cooperate to clamp the cartridge, the side of the cartridge abuts against the cartridge cushion layer to prevent the clamping member 3 from damaging the cartridge.

[0031] In some embodiments, a transverse guide member 5 is provided on the sliding table 4. The transverse guide member 5 is connected and cooperates with the mounting end plate. When the unstacking telescopic member 2 drives the clamping member 3 to move, the mounting end plate of the clamping member 3 moves along the transverse guide member 5. Specifically, the transverse guide member 5 is a guide rod, and a sliding bushing is provided on the sliding table 4. The guide rod passes through the sliding bushing and is connected to the mounting end plate.

[0032] The detection mechanism includes an upper detection member 6 and a lower detection member 7. The upper detection member 6 and the lower detection member 7 are both arranged in the separation area. The upper detection member 6 is above the lower detection member 7. The lower detection member 7 is used to detect the in-place state of the cartridge in the separation area, and the upper detection member 6 is used to detect the separation state of the cartridge in the separation area. The vertical distance between the upper detection member 6 and the lower detection member 7 is less than the height of the cartridge. The upper detection member 6 and the lower detection member 7 form an interlock, and the two cooperate to detect the splitting state of the cartridge.

[0033] When the unstacking mechanism completely separates the lowermost cartridge from the upper cartridges, the lower detection member 7 detects the lowermost cartridge and the upper detection member 6 does not detect the cartridge. When the lower detection member 7 detects the lowermost cartridge and the upper detection member 6 also detects the cartridge, it means that the lowermost cartridge has not been completely separated from the upper cartridges, and the machine needs to be stopped for adjustment.

[0034] The detection mechanism further includes a controller, preferably a PLC. The upper detection member 6 and the lower detection member 7 are both connected to the controller and transmit the detected information to the controller. The controller is connected to each vertical driving member and each clamping telescopic member. The controller can control each vertical driving member and each clamping telescopic member according to the detection results of the upper detection member 6 and the lower detection member 7.

[0035] In some embodiments, the controller is further connected to an alarm. When the upper detection member 6 and the lower detection member 7 detect abnormalities, the controller can also control the alarm to emit an alarm signal.

[0036] As a specific example of the upper detection member 6 and the lower detection member 7, the upper detection member 6 and the lower detection member 7 are optoelectronic switches. The emitting end and the receiving end of each optoelectronic switch are respectively arranged on both sides of the cartridge area and form a through-beam. Positive and negative connection positions are provided at the emitting end and the receiving end of each optoelectronic switch. A signal line is also provided at the emitting end of each optoelectronic switch. The optoelectronic switch is connected to the controller through the signal line.

[0037] With the cartridge splitting detection device of the present utility model, during the cartridge unstacking process, the splitting state of the cartridge is detected by the detection mechanism. When the detection mechanism detects that the equipment has an abnormality or the cartridge is not completely split, in order to prevent the equipment from continuing to operate abnormally during the cartridge splitting, resulting in phenomena such as the collision of the equipment servo system and the damage of the battery cells, the controller controls the alarm to emit an alarm signal and controls the unstacking mechanism to stop.

[0038] In the description of this specification, the description with reference to terms such as "one embodiment", "example", "specific example", etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0039] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
