[0030] like Figure 1 and Figure 2 As shown, the battery tail film device of this utility model embodiment includes a feeding mechanism 1, a film application mechanism 2, and a positioning mechanism 3. The feeding mechanism 1 is used to transport the battery 100 to the film application position 11 along a first direction (the first direction is the X direction shown in the figure). The battery 100 has a first side surface 101 arranged along the first direction. A protective film 102 is provided on the outside of the battery 100, and the protective film 102 has a tail film portion 103 protruding from the first side surface 101. The film application mechanism 2 includes a frame 21, a first driving member 22, and a roller 23. The first driving member 22 is mounted on the frame 21. On one side of the film application position 11 along the vertical direction (vertical direction is the Z direction in the figure), the roller 23 is rotatably mounted on the driving end of the first driving member 22. The rotation axis of the roller 23 extends along the second direction (the second direction is the Y direction in the figure). The first driving member 22 can drive the roller 23 to move along the vertical direction to apply the tail film 103 to the first side 101.

[0032] In the embodiment, the battery 100 has pasted the lower tail film, so only the upper tail film needs to be pasted, that is, the battery 100 of the present scheme only has the tail film part 103 adjacent to the top surface of the battery 100, so the film pasting mechanism 2 is arranged above the battery 100 at the film pasting position 11, and the first driving member 22 drives the roller 23 to move downward, so as to gradually roll and paste the tail film part 103 protruding from the first side surface 101 to the first side surface 101. Of course, in other embodiments, when the battery 100 pastes the upper tail film and needs to paste the lower tail film, the film pasting mechanism 2 is arranged below the battery 100 at the film pasting position 11; or when the first side surface 101 of the battery 100 has upper and lower tail films arranged at intervals along the vertical direction, the film pasting mechanism 2 is arranged on both sides of the battery 100 at the film pasting position 11, which will not be specifically exemplified here.

[0033] Further, as shown in Figure 1 and Figure 2 The feeding mechanism 1 includes a second driving member and a first clamping assembly 12, at least one side of the battery 100 along the second direction is provided with the first clamping assembly 12, the first clamping assembly 12 is arranged at the driving end of the second driving member, the first clamping assembly 12 includes a third driving member 121 and a first clamping block 122, the driving end of the third driving member 121 is arranged at intervals along the vertical direction Two first clamping blocks 122, two first clamping blocks 122 are arranged at intervals to form a first clamping groove for clamping the battery 100. The second driving member drives the first clamping assembly 12 to move to the feeding position 13 of the feeding mechanism 1, the third driving member 121 drives the two first clamping blocks 122 to open, the external feeding structure places the battery 100 in the first clamping groove, the third driving member 121 drives the two first clamping blocks 122 to clamp the battery 100 and keep the clamping state, and the second driving member drives the first clamping assembly 12 and the battery 100 to move to the feeding position 13.

[0034] Further, as shown in Figure 2 , the battery 100 is provided with the first clamping assembly 12 on both sides along the second direction, and the two first clamping assemblies 12 are arranged at the driving end of the second driving member along the second direction, in other words, the driving end of the second driving member is provided with a mounting seat 14, and the mounting seat 14 is provided with the two first clamping assemblies 12 along the second direction, and the two first clamping assemblies 12 clamp the upper and lower sides of the two ends of the battery 100 along the second direction, which can improve the clamping stability of the feeding mechanism 1 to the battery 100, and avoid the situation that one end of the battery 100 is clamped and the other end is inclined due to its own gravity.

[0035] In addition, in addition to clamping the upper and lower sides of the battery 100 for feeding, in other embodiments, the first clamping assembly 12 can also clamp the two sides of the battery 100 along the second direction for feeding. The feeding mechanism 1 comprises a second driving member and a first clamping assembly 12, the first clamping assembly 12 comprises a third driving member 121 and two first clamping blocks 122 arranged along the second direction, the two first clamping blocks 122 are arranged to form a first clamping groove for clamping the battery 100, and at least one first clamping block 122 is a movable clamping block, and the third driving member 121 is used to drive the movable clamping block to move to selectively clamp or release the battery 100. Taking the example that two third driving members 121 are provided and one movable clamping block is arranged on each third driving member 121, the third driving member 121 drives the movable clamping blocks to move away from each other along the second direction, so that the battery 100 can be placed in the first clamping groove, and the third driving member 121 drives the movable clamping blocks to move close to each other along the second direction to clamp the battery 100, and in combination with the driving of the second driving member to achieve the clamping feeding of the battery 100.

[0036] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 3 , the positioning mechanism 3 comprises a first positioning assembly 31 and a second positioning assembly 32 arranged on both sides of the film pasting position 11 along the first direction, and the battery 100 has a second side 104 arranged along the first direction and opposite to the first side 101, the first positioning assembly 31 can abut against the first side 101, and the second positioning assembly 32 can abut against the second side 104. The positions of the two sides of the battery 100 along the first direction are corrected by clamping the abutment of the first side 101 by the first positioning assembly 31 and the abutment of the second side 104 by the second positioning assembly 32, so as to improve the position accuracy of the battery 100 pasting film.

[0037] Further, as shown in Figure 3As shown, the first positioning assembly 31 is adjacent to the feeding position 13 of the feeding mechanism 1, and the first positioning assembly 31 comprises a fourth driving member 311, a fifth driving member 312 and a first positioning block 313. The fourth driving member 311 is arranged on the rack 21, and the fifth driving member 312 is in driving connection with the first positioning block 313 to drive the first positioning block 313 to move along the first direction to abut against the first side surface 101. The fifth driving member 312 is arranged on the driving end of the fourth driving member 311, and the fourth driving member 311 can drive the fifth driving member 312 and the first positioning block 313 to move along the vertical direction. When the feeding mechanism 1 feeds the battery 100, the fourth driving member 311 drives the fifth driving member 312 and the first positioning block 313 to move upward along the vertical direction, so as to avoid the interference between the feeding mechanism 1 and the first positioning assembly 31 when the feeding mechanism 1 feeds the battery 100 to the film pasting position 11. After the feeding of the battery 100 is completed, the fourth driving member 311 drives the fifth driving member 312 and the first positioning block 313 to move downward along the vertical direction, so that the first positioning block 313 is opposite to the first side surface 101, and the fifth driving member 312 drives the first positioning block 313 to move along the first direction towards the battery 100 to abut against the first side surface 101.

[0038] Further, as shown in Figure 1 and Figure 4 , the second positioning assembly 32 comprises a sixth driving member and a second positioning block 321. The sixth driving member is in driving connection with the second positioning block 321 to drive the second positioning block 321 to move along the first direction to abut against the second side surface 104. That is, after the feeding mechanism 1 feeds the battery 100 to the film pasting position 11, the sixth driving member drives the second positioning block 321 to move towards the second side surface 104 of the battery 100 and abut against the second side surface 104.

[0039] Optionally, as shown in Figure 1 , the second driving member and the sixth driving member are a double-mover linear motor module 4. The double-mover linear motor module 4 comprises a first mover 41 and a second mover 42. The first clamping assembly 12 is arranged on the first mover 41, and the second positioning block 321 is arranged on the second mover 42. For example, the motor drives the first clamping assembly 12 to feed the battery 100 along the first direction to the film pasting position 11. At this time, the first mover 41 remains stationary, and the motor drives the second mover 42 to drive the second positioning block 321 to move along the first direction towards the battery 100. By adopting the structure of the double-mover linear motor module 4, the number of driving structures can be reduced, so as to reduce the occupied space of the driving mechanism. In addition, the consistency of the moving direction of the first clamping assembly 12 and the second positioning block 321 along the first direction can be improved.

[0040] Preferably, as shown in Figure 4 and Figure 5As shown, the second positioning assembly 32 further comprises a supporting member 323, which is arranged at one side of the second positioning block 321 adjacent to the battery 100 along the first direction, and comprises an eighth driving member 3231 and a supporting block 3232. The eighth driving member 3231 is arranged at the driving end of the sixth driving member, and is in transmission connection with the supporting block 3232 to drive the supporting block 3232 to abut against the bottom surface of the battery 100 along the vertical direction. After the battery 100 is transported to the film pasting position 11 by the feeding mechanism 1, the supporting block 3232 is driven by the eighth driving member 3231 to support the bottom surface of the battery 100. At this time, the first clamping assembly 12 is used to open the first clamping groove to release the battery 100, so that the battery 100 is supported by the supporting plate, thereby facilitating the adjustment of the battery 100 along the two sides of the first direction by the first positioning assembly 31 and the second positioning assembly 32. In addition, without the supporting member 323, the first clamping assembly 12 can also be used to open the first clamping groove to support the battery 100 on the first clamping block for adjustment. Of course, the supporting plate is provided with a sensor 3233 for sensing the abutment between the supporting plate and the battery 100, so as to avoid over-driving of the eighth driving member 3231.

[0041] Further, as shown in Figure 1 and Figure 4 , the second positioning assembly 32 further comprises at least one second clamping assembly 322, which is arranged at one side of the second positioning block 321 along the second direction. The second clamping assembly 322 comprises a seventh driving member 3221 and a second clamping block 3222. The seventh driving member 3221 is arranged at the driving end of the sixth driving member, and the driving end of the seventh driving member 3221 is arranged with two second clamping blocks 3222 along the vertical direction. The two second clamping blocks 3222 are arranged to form a second clamping groove for clamping the battery 100. After the battery 100 is positionally adjusted by the first positioning assembly 31 and the second positioning assembly 32, the seventh driving member 3221 drives the second clamping block 3222 to clamp the battery 100, so as to fix the battery 100, thereby facilitating the film pasting of the film portion 103 by the film pasting mechanism 2. At this time, the second driving member can drive the first clamping assembly 12 to return to the feeding position 13 to clamp and feed the next battery 100 to be pasted with film, so as to reduce the standby time between the feeding process and the film pasting process, improve the continuity of the film pasting of the battery 100, and effectively shorten the production time of the battery 100.

[0042] In the embodiment, as shown in Figure 4As shown, the driving end of the sixth driving member is provided with a fixing seat 15, the ninth driving member 5 is arranged on the fixing seat 15, and the second clamping assembly 322 and the second positioning member are arranged at the driving end of the ninth driving member 5, so that after the tail film part 103 of the battery 100 is pasted, in the state that the battery 100 is supported by the supporting member 323, the second clamping assembly 322 releases the clamping of the battery 100 and is retreated through the ninth driving member 5, so that the second clamping assembly 322 is spaced apart from the battery 100 along the first direction, so as to facilitate the discharge of the battery 100 after pasting.

[0043] In addition, by clamping one side of the battery 100 by the second clamping assembly 322 and supporting the bottom of the battery 100 by the supporting member 323, the structural stability of the battery 100 during pasting can be effectively ensured, and the downward tilting of the battery 100 can be avoided. In the embodiment, the second clamping assembly 322 is arranged on both sides of the second positioning block 321 along the second direction, so as to ensure the clamping stability of the battery 100.

[0044] As shown, Figures 1 to 5 The working principle of the battery tail film pasting device is as follows: the second driving member drives the first clamping assembly 12 to feed the battery 100 to the pasting position 11, at this time, the second clamping assembly 322 is in an open state, the sixth driving member drives the supporting member 323 to be located below the battery 100, the eighth driving member 3231 drives the supporting block 3232 to move upward to support the battery 100, the first clamping assembly 12 releases the clamping of the battery 100, then the fourth driving member 311 drives the fifth driving member 312 and the first positioning block 313 to move downward along the vertical direction so that the first positioning block 313 is opposite to the first side surface 101, the fifth driving member 312 drives the first positioning block 313 to move along the first direction and abut against the first side surface 101, at the same time, the sixth driving member drives the second positioning block 321 to move along the first direction and abut against the second side surface 104, so as to adjust the battery 100 to be tangent to the roller 23 along the vertical direction, then the seventh driving member 3221 drives the second clamping block 3222 to clamp the battery 100, at this time, the second driving member can drive the second clamping assembly 322 to return to the feeding position 13 to clamp the next battery 100 to be pasted, then the first driving member 22 drives the roller 23 to move downward to paste the tail film part 103 to the first side surface 101, so as to complete the pasting of the tail film part 103 of the battery 100, then the first driving member 22 drives the roller 23 to move upward, the second clamping assembly 322 releases the battery 100, and the battery 100 after pasting is discharged, so as to realize the pasting of the tail film part 103 of each battery 100 in turn.
