DETAILED DESCRIPTION

[0034] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0035] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0036] Reference Figure 1 and Figure 2A battery cell labeling machine includes a label feeding mechanism 1, a label positioning mechanism 2, a label pasting mechanism 3, a battery cell positioning mechanism 4 and a machine body 5. Each mechanism is installed on the machine body 5. The label feeding mechanism 1 unwinds a material roll 6, removes labels 7 from the material roll 6 one by one, and then places the labels 7 in the label positioning mechanism 2 to position the labels 7. The label pasting mechanism 3 takes the positioned labels 7 from the label positioning mechanism 2, moves them to the battery cell positioning mechanism 4, and pastes the labels 7 on the positioned battery cells 8 to complete the labeling work of the battery cells 8.

[0037] Specifically, refer to Figure 3 and Figure 4 , the label feeding mechanism 1 includes a conveying roller group 11 and a label pick-and-place assembly 12; the conveying roller group 11 rotates each roller shaft member under the drive of the motor, and pulls out the material roll 6 wound around the conveying roller group 11, so that the label pick-and-place assembly 12 can absorb the label 7. The label pick-and-place assembly 12 includes a first suction nozzle 13 and a first driving member, and the first suction nozzle 13 is installed at the moving end of the first driving member. The first driving member can drive the first suction nozzle 13 to rise, fall and translate. The first suction nozzle 13 generates suction through vacuum negative pressure, and can absorb and take away the label 7 on the spread material roll 6. In this embodiment, the first driving member adopts a combination structure of a linear motor and a lifting cylinder to realize the lifting and translation of the first suction nozzle 13. In other embodiments, a manipulator can also be directly used to drive the first suction nozzle 13 to move.

[0038] In this embodiment, in each label feeding mechanism 1, two groups of conveying roller groups 11 and label picking and placing components 12 are provided, and the two groups of label picking and placing components 12 share a set of linear motors, which makes rational use of space and saves costs. In addition, four first suction nozzles 13 are arranged in parallel on each label picking and placing component 12, which can suck four labels 7 at a time, thereby improving work efficiency.

[0039] Reference Figure 5 The label positioning mechanism 2 includes a rotating disk 21, a positioning platform 22, a first label positioning member 23 and a second label positioning member 24. The bottom of the rotating disk 21 is driven by a motor to realize the rotation of the rotating disk 21. There are at least two groups of positioning platforms 22 radially opposite to each other along the rotating disk 21. In this embodiment, two groups of positioning platforms 22 are arranged, and each group of positioning platforms 22 is arranged with two, so that the first suction nozzles 13 on the two groups of label picking and placing components 12 can synchronously place the label 7 in the two positioning platforms 22 of one group. Each positioning platform 22 is configured with a first label positioning member 23 and a second label positioning member 24. The first label positioning member 23 can position the label 7 along the first direction, and the second label positioning member 24 can position the label 7 along the second direction. The first direction of the label 7 is defined as the length direction, and the second direction of the label 7 is defined as the width direction.

[0040] Further, refer to Figure 6 In this embodiment, each positioning platform 22 includes two parallel and spaced positioning grooves 221, and a label 7 can be placed in each positioning groove 221 to correspond to the two positions of the label 7 that need to be spaced and pasted on the battery cell 8 in one direction. The positioning groove 221 has two mutually perpendicular wide ribs 222 and long ribs 223. The first label positioning member 23 is used to push the label 7 against the wide ribs 222, and the second label positioning member 24 is used to push the label 7 against the long ribs 223. The first label positioning member 23 includes a first baffle 231 and a first driving part 232. The first driving part 232 drives the first baffle 231 to move along the length direction of the long rib 223 of the positioning groove 221, and the first baffle 231 can act on the two positioning grooves 221 at the same time, that is, the first baffle 231 can simultaneously push the labels 7 in the two positioning grooves 221 to the wide ribs 222 of the respective positioning grooves 221, thereby completing the positioning of the label 7 in the length direction. The second label positioning member 24 includes a second baffle 241 and a second driving part 242. The second driving part 242 drives the second baffle to move along the length direction of the wide baffle 222 of the positioning groove 221, so as to push the label 7 in the positioning groove 221 to the long baffle 223, and complete the positioning of the label 7 in the width direction. Among them, the positioning groove 221 is used to support the label 7. The bottom groove wall is provided with empty grooves at intervals along the length direction. Therefore, the long baffle 223 is provided with push blocks at intervals along its length direction, which can be inserted into the corresponding empty grooves on the positioning groove 221 to push the label 7. In this embodiment, two second label positioning members 24 are arranged corresponding to the two positioning grooves 221. The second driving part 242 of one of the second label positioning members 24 uses a cylinder to drive the second baffle 241; the second driving part 242 of the other second label positioning member 24 uses a motor to drive the pulley to reciprocate, and connects the second baffle 241 to the pulley, so as to realize the movement of the second baffle 241 along the length direction of the wide baffle 222 of the positioning groove 221. Such arrangement can reasonably utilize the space of the turntable. In other embodiments, the first driving part 232 and the second driving part 242 can be driven by cylinders or pulleys.

[0041] It should be noted that the support end surface in contact with the label 7 in the positioning groove 221 is provided with an anti-stick coating, and the anti-stick coating is made of nano-material coating, so that the label 7 will not adhere to the positioning groove 221, which is convenient for the label 7 to be sucked away later. After the label 7 is positioned, the turntable rotates 180°, so that the positioned label 7 is close to the label pasting mechanism 3, which is convenient for the label pasting mechanism 3 to suck the label 7 away. At the same time, the two groups of empty positioning tables 22 can continue to place labels 7 for the label feeding mechanism 1, and continue to position the label 7 through the first label positioning member 23 and the second label positioning member 24; such a cycle of work can effectively improve work efficiency.

[0042] Reference Figure 7The label pasting mechanism 3 includes a second suction nozzle 31 and a second driving member 32. The second driving member 32 drives the suction nozzle to rise, fall and translate. The second suction nozzle 31 is installed at the moving end of the second driving member 32. The second suction nozzle 31 generates suction through vacuum negative pressure, and can suck away the label 7 that has been positioned in the positioning groove 221. The second driving member 32 also drives the second suction nozzle 31 by a linear motor and a cylinder. Similarly, the second driving member 32 can also be replaced by a manipulator. The second driving member 32 drives the second suction nozzle 31 to move to the rotating disk 21, and drives the second suction nozzle 31 to descend, sucks away the label 7 that has been positioned in the positioning groove 221, and then moves to the battery positioning mechanism 4 to paste the label 7. Among them, the second driving member 32 is connected to two mounting parts 33, each mounting part 33 corresponds to a positioning platform 22, and the second suction nozzles 31 on each mounting part 33 are arranged in two groups at intervals, with two second suction nozzles 31 in each group, and the two second suction nozzles 31 in each group correspond to a positioning groove 221, so as to synchronously absorb the labels 7 placed in the two positioning grooves 221.

[0043] Reference Figure 8 and Fig. 9 The cell positioning mechanism 4 includes a fixed platform 41 and a plurality of cell positioning members 42, and the fixed platform 41 is fixed on the body 5. The cell 8 can be movably placed in the fixed platform 41, and the cell positioning member 42 is installed on the fixed platform 41. The cell positioning member 42 includes two first clamping plates 421, two second clamping plates 422, a third driving unit and a fourth driving unit. The third driving unit uses a cylinder to drive the two first clamping plates 421 to move closer or farther away, so as to position the length direction of the cell 8. The fourth driving unit also uses a cylinder to drive the two second clamping plates 422 to move closer or farther away, so as to position the width direction of the cell 8. The first clamping plate 421 and the second clamping plate 422 are both provided with a supporting part, which is lifted at the bottom of the cell 8 by the supporting part so that the cell 8 can be kept in a horizontal state; and the second suction nozzle 31 can press down the label 7, and when it is pasted on the cell 8, the cell 8 will not be offset in the height direction, so as to ensure that the position of the label 7 is accurately pasted. The supporting part can be a structure such as a convex block or a convex column fixedly connected to the corresponding clamping plate. In this embodiment, there are two areas on the fixed platform 41, and eight battery cell positioning members 42 are arranged in each area, divided into four rows, two in each row. Among them, in each row of two adjacent positioning members, the first clamping plates 421 are connected as a whole and share a third driving unit; for the middle two rows, along the direction of vertical arrangement, that is, along the direction of arrangement, in the two adjacent positioning members, the second clamping plates 422 are connected as a whole and share a fourth driving unit; in this way, costs can be saved.

[0044] Reference Figure 2 and Fig.10, a conveyor line 9 for conveying the battery cell 8 is provided at the bottom of the body 5. A material tray 91 for placing the battery cell 8 is transported on the conveyor line 9. A lifting tray 51 and a lifting member are also provided at the bottom of the body 5, and the lifting member can be a lifting cylinder. The lifting tray 51 is driven by the lifting cylinder to be lifted and lowered, and can lift the material tray 91 and separate it from the conveyor line 9. A clearance hole 411 is provided on the fixed platform 41 corresponding to the battery cell 8, so that after the material tray 91 is raised, the battery cell 8 can be raised from the clearance hole 411 to the fixed platform 41, so that the first clamping plate 421 and the second clamping plate 422 can position and clamp the battery cell 8. When the battery cell 8 is positioned, the two second suction nozzles 31 on the label pasting mechanism 3 move to the top of the battery cell 8, and the two second suction nozzles 31 descend, so that the label 7 on the second suction nozzle 31 can be directly pasted on the corresponding position of the battery cell 8 to complete the pasting. Subsequently, the second clamping plate 422 and the first clamping plate 421 return to their original positions, the battery cells 8 fall back into the tray 91 , and the lifting tray 51 drives the tray 91 to descend, so that the tray 91 returns to the conveyor line 9 and is transported to the next station.

[0045] Reference Figure 1 In this embodiment, the labeling machine for the battery cell 8 has two stations on the left and right. Each station has four groups of label feeding mechanisms 1, four groups of label positioning mechanisms 2, four groups of label pasting mechanisms 3 and battery cell positioning mechanisms 4. Among them, the left station is used to paste the labels 7 at both ends of the battery cell 8 in the width direction. After the left station completes the labeling of the battery cell 8, the battery cell 8 is moved to the right station through the conveyor line 9, and then the right station pastes the labels 7 at both ends of the length direction of the battery cell 8. In this embodiment, the four groups of label feeding mechanisms 1 are symmetrically arranged on both sides of the conveyor line 9 in pairs, and one group of label feeding mechanisms 1 is two; the four groups of label positioning mechanisms 2 are symmetrically arranged on both sides of the conveyor line 9 in pairs, and one group of label positioning mechanisms 2 is one; the four groups of label pasting mechanisms 3 are symmetrically arranged on both sides of the conveyor line 9, and one group of label pasting mechanisms 3 is one; the battery cell positioning mechanism 4 is arranged above the conveyor line 9. Such a setting can reasonably utilize the equipment space layout, make the equipment mechanism more compact, and can simultaneously perform labeling actions on multiple groups of battery cells 8, thereby improving work efficiency.
