The adhesive tape sticking system comprises a first station, a second station, a third station and a fourth station, the fixture 100 is arranged on the turntable 300, and the fixture 100 clamps the battery cell 400 in the rotation process of the turntable 300 and can sequentially pass through the first station, the second station, the third station and the fourth station.

Referring to fig. 2 and 3, the clamping apparatus includes a rotating plate 11 and a clamping assembly.

The rotating plate 11 is rotatably connected to the turntable 300 around a rotating axis parallel to the plane of the turntable 300, the rotating plate 11 rotates between a first limit position and a second limit position during the rotation around the rotating axis, and when the rotating plate 11 is located at the first limit position or the second limit position, the rotating plate 11 and the turntable 300 can be relatively fixed.

The centre gripping subassembly includes first splint 12 and second splint 13, first splint 12 fixed connection in rotor plate 11, second splint 13 and the corresponding setting of first splint 12 and rotor plate 11 to form the centre gripping position that is used for centre gripping electricity core 400 between first splint 12 and second splint 13, second splint 13 can be close to or keep away from relative first splint 12 under the exogenic action, thereby can be with electric core 400 centre gripping in fixed position when being close to.

Through setting up foretell anchor clamps on the carousel, rotate rotor plate 11 to second extreme position, then place electric core 400 in the centre gripping position, and be close to first splint 12 with second splint 13 in order to grasp electric core 400, next rotate rotor plate 11 to first extreme position, only need to guarantee that rotor plate 11 rotates the turned angle of first extreme position from second extreme position for 90, just can revolute the axis of rotation with electric core 400 of centre gripping at the centre gripping position and rotate 90. Can transport electric core 400 on the anchor clamps to each station and carry out the rubberizing when carousel 300 rotates, compare in current transport and the upset of carrying out electric core 400 through the cantilever beam structure, the utility model provides an anchor clamps can realize electric core 400's upset on carousel 300, and the cantilever beam structure can only be used for electric core 400's transport and need not overturn to electric core, therefore the cantilever beam need not set up tilting mechanism structurally to not receive the influence of tilting mechanism's weight, also guaranteed the reliability of cantilever beam structure transport, thereby improved transport speed effectively, improved the packaging efficiency of lithium cell.

It will be understood that fig. 2 is a schematic view of the adhesive application system with the pivotal plate in the first extreme position.

Further, the plane of the first clamping plate 12 is parallel to the rotation axis; the second clamp 13 is parallel to and opposite the first clamp 12, such that the plane of the second clamp 13 is also parallel to the axis of rotation.

It should be noted that, for the turntable 300, the rotation axis is parallel to the plane of the turntable 300, that is, if the turntable 300 is placed horizontally, the rotation axis is a horizontal axis; for two parallel clamping plates, the plane of the clamping plate is the clamping plane of the finger clamping plate clamping the battery cell 400.

Meanwhile, the battery cells 400 in other embodiments are all battery cells 400 formed by stacking two small-sized battery cells. The battery cell 400 has a substantially rectangular parallelepiped structure. And taping the battery cell 400 means taping the battery cell 400 at the bottom and side surfaces thereof. The reason why the cell 400 needs to be turned over is that the cell 400 needs to be kept in a certain state in the previous processing process to facilitate the processing, but the state of the cell 400 needs to be changed when the tape is to be attached, and therefore the cell 400 needs to be turned over. In short, the conventional flipping method flips the stacked battery cells 400 while transporting them by a transport mechanism of a cantilever link structure.

Because the place plane of first splint 12 and second splint 13 all is parallel with the axis of rotation, consequently the centre gripping plane in opposite directions of two splint can directly respectively the butt in the surface of the relative both sides of electricity core 400, so, it is the example to use rotor plate 11 to be in the side level of second extreme position and electricity core 400 by the centre gripping, splint place plane and axis of rotation are the horizontally this moment, can be through the side surface that centre gripping electricity core 400 corresponds, ensure that electricity core 400 is after rotating 90 along with rotor plate 11, the bottom surface level of electricity core 400 is placed, and the side becomes vertical the placing, the angle of electricity core 400 upset is corresponding with the angle of rotor plate 11 upset, convenient processing.

It should be further explained that the above-mentioned clamp is provided for facilitating the lithium battery processing and improving the efficiency, and mainly by simplifying the carrying mechanism, the carrying speed is improved to improve the efficiency, and if other processing steps of the lithium battery need to be kept as unchanged as possible, and if the plane of the clamping plate is not parallel to the rotation axis, the subsequent processing equipment needs to be adjusted, which is inconvenient for the lithium battery processing, and therefore, is not preferable.

It can be understood that the preset direction is variable and changes along with the rotation of the rotating plate 11, and the preset direction is changed synchronously while the rotating plate 11 changes, so that the preset direction can be always perpendicular to the plane of the rotating plate 11.

In some embodiments, the first clamping plate 12 includes a first connecting portion and a first clamping portion, the first connecting portion is fixedly connected to one side of the rotating plate 11, the other end of the first connecting portion extends from one end of the rotating plate 11 away from the turntable 300, and the first clamping portion is located on one side of the first connecting portion and located at one end of the first connecting portion extending out of the rotating plate 11.

Meanwhile, the plane of the first connecting portion, the plane of the second connecting portion, and the surfaces of the two clamping portions for clamping the battery cell 400 are parallel to each other.

Referring to fig. 2, in some embodiments, the clamping apparatus further includes a fixing block 16 and a wire rail 17, the fixing block 16 is fixedly connected to the rotating plate 11, the wire rail 17 is movably disposed on the fixing block 16, and the second clamping plate 13 is fixedly connected to one side of the wire rail 17 so as to be close to or far from the first clamping plate 12 during moving along with the wire rail 17.

Further, the wire track 17 is located the one side that carousel 300 was kept away from to rotor plate 11, and second splint 13 fixed connection deviates from one side of rotor plate 11 in wire track 17, and the first clamping part on the first splint 12 is connected in the one end that first connecting portion stretches out rotor plate 11 to guarantee that the second clamping part of second splint 13 corresponds at the first clamping part of presetting orientation with first splint 12, make things convenient for centre gripping electricity core 400.

In some embodiments, the clamp further includes a first connecting plate 18 and a mounting seat 19, the mounting seat 19 is fixedly connected to one end of the wire rail 17, and the second clamping plate 13 is fixedly connected to one side of the mounting seat 19 facing the first clamping plate 12, so that the second clamping plate 13 corresponds to the first clamping plate 12; the first connecting plate 18 is fixedly connected to a side of the rotating plate 11 facing away from the first connecting portion, and the fixing block 16 is fixedly connected to the first connecting plate 18.

In some embodiments, the clamp further comprises a guide block 20, the guide block 20 is fixedly connected to the other side of the wire rail 17 facing away from the second clamping plate 13, the guide block 20 can move closer to or away from the rotating plate 11 along with the movement of the wire rail 17, and both the guide block 20 and the second clamping plate 13 are connected with the wire rail 17, so that the movement of the second clamping plate 13 can be adjusted by adjusting the movement of the guide block 20.

Further, the clamp further includes a first elastic member 21, and the first elastic member 21 is connected between the rotating plate 11 and the guide block 20, and is used for providing a pre-tightening force for enabling the second clamping plate 13 to have a moving tendency towards the approaching direction of the first clamping plate 12, that is, the first elastic member 21 indirectly provides an external force for enabling the second clamping plate 13 to approach the first clamping plate 12 and clamp the battery cell 400 by connecting with the guide block 20.

In some embodiments, the wire rail 17 is disposed lengthwise along a predetermined direction and movably disposed on the fixing block 16 along the predetermined direction, opposite ends of the wire rail 17 are respectively located at opposite sides of the rotating plate 11 in the predetermined direction, and the second clamping plate 13 and the guide block 20 respectively connected to the opposite sides of the wire rail 17 are also respectively located at opposite ends of the wire rail 17 along the predetermined direction.

In this way, the guide block 20 and the second clamping plate 13 are respectively located at two opposite sides of the rotating plate 11, and the guide block 20 and the second clamping plate 13 are linked by the linear rail 17, when the guide block 20 is close to the rotating plate 11, the second clamping plate 13 is far away from the rotating plate 11, so when the first elastic member 21 is connected between the rotating plate 11 and the guide block 20, the first elastic member 21 provides a pushing force to the guide block 20, that is, the guide block 20 is pushed outwards relative to the rotating plate 11, thereby indirectly providing an external force to the second clamping plate 13 moving towards the first clamping plate 12.

In other embodiments, the guide block 20 may be located on the same side of the rotating plate 11 as the second clamping plate 13, and the guide block 20 and the second clamping plate 13 are simultaneously close to and far from the rotating plate 11, so that after the first elastic member 21 is connected between the guide block 20 and the rotating plate 11, the first elastic member 21 provides a pulling force to the guide block 20, thereby indirectly providing an external force for moving the second clamping plate 13 toward the first clamping plate 12.

Of course, it is preferable to dispose the guide blocks 20 and the second clamping plates 13 on opposite sides of the pivotal plate 11 for convenience of arrangement, and the subsequent embodiment is designed based on the guide blocks 20 and the second clamping plates 13 on opposite sides of the pivotal plate 11.

In some embodiments, the fixture further includes a first guide rod 22, one end of the first guide rod 22 is fixedly connected to one side of the rotating plate 11, to which the first connecting portion is connected, and the other end of the first guide rod 22 penetrates through the guide block 20 to guide the movement of the guide block 20.

Further, the first guide rod 22 extends along a predetermined direction, and a limiting portion is disposed at an end of the first guide rod 22 away from the rotating plate 11 to prevent the guide block 20 from being separated from the first guide rod 22.

It should be explained that, as shown in fig. 4, the first guide rods 22 include two first limiting parts, each of the first limiting parts is a rod-shaped structure connected between the two first guide rods 22, and opposite ends of the first limiting part are respectively connected to ends of the two first guide rods 22, so as to prevent the guide block 20 from being separated from the first guide rods 22.

Meanwhile, for the wire rail 17 and the first elastic member 21, the number of the first elastic members 21 of the wire rail 17 is also two, the guide block 20 can be a whole block, the guide block 20 is connected with the two wire rails 17 at the same time, and the two first guide rods 22 are all arranged in the guide block 20 in a penetrating manner. The two first guide rods 22 and the two first elastic members 21 are provided mainly for ensuring the reliability of the jig.

Specifically, the first elastic element 21 is a spring, the spring is sleeved on the first guide rod 22, and two ends of the spring respectively abut against the rotating plate 11 and the guide block 20, so as to provide a pre-tightening force that is a tendency of the guide block 20 moving toward the first limiting portion of the first guide rod 22.

In some embodiments, the fixture further includes a first limiting member 23 and a second limiting member 24, the first limiting member 23 is fixedly connected to a side of the first clamping plate 12 facing the mounting base 19, the second limiting member 24 is movably disposed on a side of the mounting base 19 facing the first clamping plate 12, and the second limiting member 24 and the first limiting member 23 are correspondingly disposed to form a fixing position for fixing the battery cell 400 located at the clamping position between the first limiting member 23 and the second limiting member 24.

Further, the fixture further includes a second elastic member 25, one end of the second elastic member 25 is connected to one side of the mounting seat 19 facing the first clamping plate 12, the other end of the second elastic member 25 extends toward the first clamping plate 12, and the second limiting member 24 is fixedly connected to the other end of the second elastic member 25 away from the mounting seat 19, and the second limiting member 24 can be close to or away from the first limiting member 23 along with the mounting seat 19, so as to fix the battery cell 400 located at the clamping position when being close to the first limiting member 23.

It can be understood that the clamping and releasing of the battery cell 400 are both realized by the movement of the mounting seat 19, and the mounting seat 19 moves towards the first clamping plate 12, so that the second clamping plate 13 and the second limiting member 24 clamp and fix the battery cell 400, thereby clamping the battery cell 400; when the mounting seat 19 is far away from the first clamping plate 12, both the second clamping plate 13 and the second limiting member 24 can be separated from the battery cell 400, so that the battery cell 400 can be released.

It should be explained that, when the battery cell 400 is clamped at the clamping position, one side of the connection piece at the head end of the battery cell 400 is clamped in the first locating part 23, the second locating part 24 moves along with the mounting seat 19 and is close to the first locating part 23, and the second locating part 24 can be abutted against the other side of the connection piece, which is far away from the first locating part 23, so that the connection piece of the battery cell 400 is clamped by being matched with the first locating part 23, and the connection piece can be fixed and the battery cell 400 can be prevented from being separated from the clamping position to a certain extent.

The second elastic element 25 is used to provide a pressure for pressing the second limiting element 24 against the connecting sheet, that is, the fixing position for fixing the battery cell 400 formed by the first limiting element 23 and the second limiting element 24 is the fixing position for connecting the connecting sheet of the battery cell 400. Meanwhile, the first elastic member 21 also serves to protect the connection pieces of the battery cell 400 to some extent.

If the second locating part 24 is also fixedly connected to the mounting base 19, the mounting base 19 is actually driven by the first elastic part 21, when the mounting base 19 drives the second clamping plate 13 and the second locating part 24 to move towards the first clamping plate 12 and the second clamping plate 13 abuts against and presses the battery cell 400, the pressure of the second clamping plate 13 on the battery cell 400 is the elastic force of the first elastic part 21, and the two clamping plates are clamped on the two opposite sides of the battery cell 400, so that the contact area is large, and the first elastic part 21 can adopt a spring with a large elastic coefficient. At this time, the second limiting member 24 is fixedly connected to the mounting base 19, so that the second limiting member 24 directly abuts against the connecting piece, the pressure is the elastic force of the first elastic member 21, and the pressure is large, which may damage the connecting piece.

After the second elastic member 25 is adopted, the second elastic member 25 may adopt a spring having a smaller elastic coefficient than the first elastic member 21, and when the second limiting member 24 abuts against the connecting piece at this time, the pressure of the second limiting member 24 on the connecting piece is the elastic force of the second elastic member 25, and the pressure is small, so that the connecting piece can be protected.

In some embodiments, the clamping apparatus further includes a second guiding rod 26, one end of the second guiding rod 26 is fixedly connected to the mounting seat 19, the other end of the second guiding rod 26 extends toward the first clamping plate 12, the second elastic member 25 is sleeved on the second guiding rod 26, and the second limiting member 24 is slidably disposed on the second guiding rod 26.

In practical application, the second limiting part 24 includes a third connecting portion slidably connected to the second guide bar 26 and a second limiting portion fixedly connected to the third connecting portion, the second limiting portion is used for cooperating with the first limiting part 23 to fix the connecting piece of the battery cell 400, the second limiting part 24 is divided into two parts according to the effect, and the second limiting part 24 can cooperate with the first limiting part 23 to fix the connecting piece of the battery cell 400 more conveniently.

In other embodiments, the second limiting member 24 is slidably disposed on the second guiding rod 26, and the sliding distance of the second limiting member 24 does not need to be long, so a blind hole may also be formed on the second limiting member 24, one end of the second guiding rod 26 far away from the mounting seat 19 is shot into the blind hole, and the second limiting member 24 does not separate from the second guiding rod 26 during the working process, and one end of the second guiding rod 26 far away from the mounting seat 19 does not abut against the bottom of the blind hole, so as to ensure that the pressure is not too large when the second limiting member 24 abuts against the connecting piece.

In other words, under the condition that the second guide rod 26 is vertical, the second elastic element 25 only receives the gravity of the second limiting element 24, and it is necessary to ensure that the second guide rod 26 does not disengage from the blind hole at this time; and when the second clamping plate 13 abuts against the battery cell 400, the second limiting member 24 abuts against the connecting sheet, and the second elastic member 25 is compressed, at this time, there is still a safety gap between the end of the second guide rod 26 far away from the mounting seat 19 and the bottom of the blind hole.

Of course, it is preferable that the second limiting member 24 includes a third connecting portion and a second limiting portion, and in this way, a blind hole does not need to be provided, and the length of the second guide rod 26 and the depth of the blind hole do not need to be considered according to the sliding distance, which is convenient for processing.

In still other embodiments, a guide hole is formed on a side of the mounting seat 19 facing the first clamping plate 12, the guide rod 26 is fixedly connected with the second limiting member 24, the other end of the guide rod 26 is movably limited in the guide hole, and the second elastic member 25 is connected between the second limiting member 24 and the mounting seat 19.

Thus, the guide rod 26 moves in the guide hole and is fixedly connected with the second limiting member 24, so that the second limiting member 24 can be guided to move, and meanwhile, the guide rod 26 is limited in the guide hole, so that the second limiting member 24 can be prevented from falling off. When the second elastic member 25 is a spring, the spring may be directly fitted to the guide bar 26, and both ends of the spring may be in contact with the mounting base 19 and the second stopper 24, respectively.

It should be explained that, the end of the guiding rod 26 away from the second limiting member 24 is limited in the guiding hole, which may be implemented by that the guiding rod 26 includes a rod body and a protruding portion protruding from one end of the rod body, the protruding portion is movable in the guiding hole and is limited in the guiding hole, and the rod body can extend out of the guiding hole during moving along with the protruding portion.

In the above three embodiments, the arrangement form of the second guide rod 26 is described, and the second guide rod 26 functions to guide the movement of the second stopper 24, and the arrangement form is not limited.

In some embodiments, a side of the first limiting member 23 facing the second limiting member 24 is provided with a limiting protrusion engaged with the connecting sheet of the battery cell 400, and a side of the second limiting member 24 facing the first limiting member 23 is provided with a limiting groove engaged with the connecting sheet of the battery cell 400, when the connecting sheet of the battery cell 400 is engaged with the limiting protrusion, the head of the battery cell 400 faces the turntable 300, the limiting protrusion prevents the battery cell 400 from moving in a direction away from the turntable 300, and the limiting groove limits the movement of the battery cell 400 in a direction away from or close to the turntable 300.

In some embodiments, the number of the first limiting members 23, the second limiting members 24, the second guide rods 26, and the second elastic members 25 also includes two, so as to ensure that the fixing of the battery cell 400 by the first limiting members 23 and the second limiting members 24 is more reliable, and prevent the battery cell 400 from moving at the clamping position.

In some embodiments, the fixture further includes a first limiting rod 28 and a second limiting rod 29, and both the first limiting rod 28 and the second limiting rod 29 are fixedly connected to the rotating plate 11.

When the rotating plate 11 rotates around the rotating axis to the first limit position along the first rotating direction, the first limiting rod 28 is limited on the rotating disc 300 to limit the rotating angle of the rotating plate 11 around the rotating axis relative to the rotating disc 300 along the first rotating direction.
