[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0047] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

In addition, if "and / or", "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0048] In the related art, when the battery is transported, the material conveyor belt is adjusted to be larger than the width of the battery to avoid the phenomenon of jamming during transportation. However, in the process of the battery being transported on the material conveyor belt, due to the wider width of the material conveyor belt, the battery may have a position deviation of left and right deflection or rotation. When the manipulator grabs the battery from the material conveyor belt to the test fixture, the position deviation of the battery will cause the manipulator to be unable to correctly place the battery on the test fixture. Therefore, how to correct the position of the battery has become a problem that needs to be solved urgently.

[0049] Reference below Figures 1 to 5 To describe the battery position correction device of the embodiment of the utility model.

[0050] Please refer to Figure 1The battery position correction device of the utility model includes a storage platform 100, a position fixing component 200, a first propulsion component 300, and a second propulsion component 400. The position fixing component 200 is arranged at the edge of the storage platform 100, and the first propulsion component 300 and the second propulsion component 400 are both arranged on the storage platform 100, and the first propulsion component 300 and the second propulsion component 400 are placed perpendicular to each other on the storage platform 100. The first direction X is a vertical direction, and the first propulsion component 300 moves along the vertical direction to make the target battery group be pushed onto the position fixing component 200 along the vertical direction. As the first propulsion component 300 is pushed in the vertical direction, the horizontal edge of the target battery group contacts the horizontal edge of the position fixing component 200, and as the first propulsion component 300 is continuously pushed, the horizontal edge of the target battery group is completely in contact with the horizontal edge of the position fixing component 200, thereby completing the correction of the position of the target battery group. The second direction Y is the horizontal direction, and the second propulsion assembly 400 moves along the horizontal direction to propel the target battery pack onto the position fixing assembly 200 along the vertical horizontal direction. As the second propulsion assembly 400 propels in the horizontal direction, the vertical edge of the target battery pack contacts the position fixing assembly 200, and as the second propulsion assembly 400 continues to propel, the vertical edge of the target battery pack completely fits with the vertical edge of the position fixing assembly 200. After the first propulsion assembly 300 and the second propulsion assembly 400 complete the propulsion, the target battery pack fits on the position fixing assembly 200, completing the position correction of the target battery pack, thereby reducing the failures caused by position deviation during the target battery pack test process and improving the test efficiency.

[0051] It should be noted that the working order of the first propulsion assembly 300 and the second propulsion assembly 400 in the embodiment of the present application is that the first propulsion assembly 300 propels forward and then the second propulsion assembly 400 propels forward. In other embodiments, the working order of the first propulsion assembly 300 and the second propulsion assembly 400 can be set according to actual needs, and this application does not make any specific restrictions.

[0052] Please refer to Figures 1 to 3In some embodiments, the first propulsion assembly 300 includes a first driving assembly (not shown in the figure), a first propulsion plate 310, a second propulsion plate 320, a first connecting rod 330, a second connecting rod 340 and a first limiting rod 350; the first connecting rod 330 is arranged between the first propulsion plate 310 and the second propulsion plate 320; the second connecting rod 340 is arranged between the first propulsion plate 310 and the second propulsion plate 320; it can be understood that the first connecting rod 330 and the second connecting rod 340 have the same length and are fixedly connected between the first propulsion plate 310 and the second propulsion plate 320. When the second propulsion plate 320 moves, the second propulsion plate 320 drives the first propulsion plate 310 to move through the first connecting rod 330 and the second connecting rod 340. One end of the first limiting rod 350 is connected to the second pushing plate 320, and the other end extends in the opposite direction of the first direction X. The first limiting rod 350 connects the first driving assembly and the second pushing plate 320. When the first driving assembly drives the second pushing plate 320 to move in the first direction X, the second pushing plate 320 pushes the first pushing plate 310 to move in the first direction X through the first connecting rod 330 and the second connecting rod 340, so that the target battery group moves along the first direction X until the horizontal edge of the target battery group is completely in contact with the horizontal edge of the position fixing assembly 200.

[0053] Please refer to Figures 1 to 3 In some embodiments, the second propulsion assembly 400 includes a second drive assembly (not shown in the figure), a third propulsion plate 410, a fourth propulsion plate 420, a third connecting rod 430, a fourth connecting rod 440 and a second limit rod 450; the third connecting rod 430 is arranged between the third propulsion plate 410 and the fourth propulsion plate 420; the fourth connecting rod 440 is arranged between the third propulsion plate 410 and the fourth feed plate; it can be understood that the third connecting rod 430 and the fourth connecting rod 440 have the same length and are fixedly connected between the third propulsion plate 410 and the fourth propulsion plate 420. When the fourth propulsion plate 420 moves, the third propulsion plate 410 drives the first propulsion plate 310 to move through the third connecting rod 430 and the fourth connecting rod 440. One end of the second limiting rod 450 is connected to the third thrust plate 410, and the other end extends along the second direction Y. The second limiting rod 450 connects the first driving assembly and the fourth thrust plate 420. When the first driving assembly drives the fourth thrust plate 420 to move along the second direction Y, the fourth thrust plate 420 pushes the third thrust plate 410 to move in the second direction Y through the third connecting rod 430 and the fourth connecting rod 440, so that the target battery moves along the second direction Y until the vertical edge of the target battery group is completely in contact with the horizontal edge of the position fixing assembly 200.

[0054] Please refer to Figures 1 to 3In some embodiments, the storage platform 100 is provided with a first sliding slot 110 and a second sliding slot 120, the first driving assembly passes through the first sliding slot 110 and is connected to the first limiting rod 350, and the first driving assembly passes through the second sliding slot 120 and is connected to the second limiting hole. It can be understood that the cross-section of the connection portion between the first driving assembly and the first limiting rod 350 is smaller than the first sliding slot 110, the first driving assembly is arranged on a side of the storage platform 100 away from the first limiting rod 350, and the connection portion between the first driving assembly and the first limiting rod 350 passes through the first sliding slot 110 and is connected to the first limiting rod 350. When the first driving assembly is driven, the connection portion of the first limiting rod 350 drives the first limiting rod 350 to move, so that the first propulsion assembly 300 is driven along the first direction X, so that the target battery pack moves along the first direction X to the position fixing assembly 200.

[0055] It should be noted that the driving process of the first driving component driving the second propulsion component 400 is consistent with the driving process of the first driving component driving the first driving component, which will not be repeated here.

[0056] Please also read Figure 1 and Figure 3 In some embodiments, a first buffer protection block (not shown in the figure) is provided on the first propulsion plate 310, and a second buffer protection block (not shown in the figure) is provided on the third propulsion plate 410. Both the first buffer protection block and the second buffer protection block are used to protect the target battery pack. The materials of the first buffer block and the second buffer block can be rubber, foam plastic, silicone or cork, which is not specifically limited in this application. When the first buffer block or the second buffer block contacts the target battery pack, a buffering effect is generated on the contact of the first propulsion assembly 300 or the second propulsion assembly 400 with the target battery, thereby avoiding deformation or damage of the target battery pack caused by the collision caused by the contact between the first propulsion assembly 300 and the target battery pack.

[0057] Please also read Figures 1 to 4In some embodiments, the first driving assembly includes a first cylinder 510 and a first driving part 520, and the first cylinder 510 drives the first driving part 520 to move along the first direction X, wherein the first driving part 520 includes a first driving plate 521 and a first elastic member 522, one end of the first elastic member 522 abuts against the first driving plate 521, and the other end abuts against the second propulsion plate 320, the first elastic member 522 is sleeved on the first limiting rod 350, the first driving plate 521 is provided with a first limiting hole, and the first limiting rod 350 is passed through the first limiting hole; it can be understood that the first driving plate 521 passes through the first sliding groove 110 to connect the first limiting rod 350 and the first cylinder 510. When the first cylinder 510 drives the first driving plate 521 to move along the first direction X, the first driving plate 521 drives the first limiting rod 350 and the first elastic member 522, so that the second pushing plate 320 pushes the first pushing plate 310 through the first connecting rod 330 and the second connecting rod 340, so that the target battery pack moves along the first direction X to fit with the position fixing assembly 200. It can be understood that the elastic member can be a spring or a spring sheet. When the elastic member is a spring, the spring is sleeved on the first limiting rod 350. The cylinder drives the first driving plate 521 to move along the first direction X. Since the two ends of the spring respectively abut the first driving plate 521 and the second pushing plate 320, when the compression amount of the spring reaches a certain degree, the spring pushes the second pushing plate 320 to move along the first direction X. At this time, the first pushing plate 310 moves along the first direction X with the second pushing plate 320, pushing the target battery pack to the position fixing assembly 200. After the target battery pack is pushed to the position fixing assembly 200, if the first driving assembly drives the first propulsion plate 310 to continue to move along the first direction X, the spring is subjected to a force from the second propulsion plate 320 in the opposite direction of the first direction X, and the spring is compressed, thereby playing a buffering role to protect the target battery pack and prevent the target battery pack from being damaged.

[0058] The first driving assembly includes a second cylinder 610 and a second driving part 620, and the second cylinder 610 drives the second driving part 620 to move along the second direction Y, wherein the second driving part 620 includes a second driving plate 621 and a second elastic member 622, one end of the second elastic member 622 abuts against the first driving plate 521, and the other end abuts against the fourth propulsion plate 420, the second elastic member 622 is sleeved on the second limiting rod 450, the second driving plate 621 is provided with a second limiting hole, and the second limiting rod 450 is passed through the second limiting hole; it can be understood that the second driving plate 621 passes through the second sliding groove 120 to connect the second limiting rod 450 and the second cylinder 610. When the second cylinder 610 drives the second driving plate 621 to move along the second direction Y, the second driving plate 621 drives the second limiting rod 450 and the second elastic member 622, so that the fourth pushing plate 420 pushes the third pushing plate 410 through the third connecting rod 430 and the fourth connecting rod 440, so that the target battery group moves along the second direction Y to fit with the position fixing assembly 200.

[0059] It should be noted that the driving process of the second elastic member 622 is the same as that of the first elastic member 522, which will not be described again.

[0060] Please also read Figure 1 and Figure 2 In some embodiments, the first propulsion plate 310 is provided with a first positioning hole (not shown in the figure) and a second positioning hole (not shown in the figure), and the second propulsion plate 320 is provided with a third positioning hole and a fourth positioning hole, the first positioning hole and the third positioning hole correspond to each other, the second positioning hole and the fourth positioning hole correspond to each other, the first connecting rod 330 is detachably connected between the first positioning hole and the second positioning hole, and the second connecting rod 340 is detachably connected between the second positioning hole and the fourth positioning hole. It can be understood that the first propulsion rod and the second propulsion rod have the same length, and the first propulsion rod can be connected between the first positioning hole and the second positioning hole by a screw or a buckle, which is not limited in this application. When the first propulsion rod needs to be replaced, the first propulsion rod can be disassembled and another propulsion rod can be installed to adapt to different target battery packs, thereby controlling the propulsion force of the target battery pack to protect the target battery pack.

[0061] Please also read Figure 1 , Figure 2 and Figure 5 In some embodiments, the position fixing assembly 200 includes a first fixing plate 210 and a second fixing plate 220, wherein the first fixing plate 210 is disposed at the edge of the storage platform 100 along the first direction X, and the second fixing plate 220 is disposed at the edge of the storage platform 100 along the second direction Y; the first fixing plate 210 and the second fixing plate 220 are used to prevent the battery pack from falling off the storage platform 100. It can be understood that when the first propulsion assembly 300 pushes the target battery pack to the first fixing plate 210, the edge of the target battery pack is attached to the first fixing plate 210, the placement position of the target battery pack is corrected, and the target battery pack is prevented from falling off the storage platform 100, so as to protect the target battery pack.

[0062] See also Figure 1 , Figure 2 and Figure 5In some embodiments, the first fixing plate 210 further includes a first position sensor (not shown in the figure), and the second fixing plate 220 further includes a second position sensor (not shown in the figure). When the first position sensor and the second position sensor detect that the target battery pack is placed within the preset placement position range, the first propulsion assembly 300 propels the target battery pack to the first fixing plate 210, and the second propulsion assembly 400 propels the target battery pack to the second fixing plate 220. When the first position sensor and the second position sensor do not detect that the target battery pack is placed within the preset prevention position range, the first propulsion assembly 300 and the second propulsion assembly 400 are in a standby state, waiting for the target battery pack to be placed on the storage table 100.

[0063] The embodiment of the second aspect of the utility model proposes a battery testing system, including a battery position correction device, a battery testing device and a manipulator device as described in the first aspect, wherein the battery position correction device is arranged within the telescopic range of the manipulator device, and is used to correct the placement position of the target battery pack; the battery testing device is arranged within the telescopic range of the manipulator device, and is used to test the battery quality of the target battery pack; the manipulator device is arranged above the battery position correction device and the battery testing device, and is used to clamp the target battery pack from the battery position correction device to the battery testing device for quality inspection. It can be understood that the manipulator device is used to place the target battery pack in the battery position correction device for position correction, and the target battery pack after position correction is placed in the battery testing device, so that the target battery pack can be correctly placed in the battery testing device, thereby reducing the faults caused by the position deviation of the target battery pack during the battery testing process and improving the testing efficiency.
