[0017] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0018] like Figures 1 to 4 As shown in the figure, this application embodiment provides a battery cell alignment device, including an alignment base 1 and an upper alignment mechanism 2. The alignment base 1 is equipped with an alignment clamp 3, which has an alignment position. The upper alignment mechanism 2 includes an alignment lifting assembly 21, an upper alignment horizontal movement assembly 22, an upper alignment assembly 23, and an upper blowing assembly 24. The upper blowing assembly 24 is connected to the upper alignment assembly 23, the upper alignment assembly 23 is slidably connected to the alignment lifting assembly 21, and the alignment lifting assembly 21 is slidably connected to the upper alignment horizontal movement assembly 22. The upper alignment assembly 23 is provided with an upper alignment gripper 231, and the upper blowing assembly 24 is provided with an upper air outlet 241. The upper alignment gripper 231 and the upper air outlet 241 are located above the alignment position.

[0019] The cell alignment device of this application includes an alignment base 1 and an upper alignment mechanism 2. When aligning the cells, the stacked cell assembly 7 is first placed vertically in the alignment position. Then, the upper alignment transverse component 22 moves the upper alignment component 23 and the upper blowing component 24 to directly above the cell assembly 7. Next, air is blown onto the cell assembly 7 from the upper air outlet 241 of the upper blowing component 24, loosening the cells and reducing friction between adjacent cells. Then, the alignment lifting component 21 moves the upper alignment gripper 231 downwards, pressing the cell assembly 7 and using gravity to achieve vertical alignment of the cells. The cell alignment device of this application can automatically loosen the stacked cells and achieve alignment without manual correction, improving work efficiency.

[0020] like Figure 4 As shown, to facilitate the placement of the battery cell assembly 7 on the alignment fixture 3, the alignment base 1 includes an alignment platform 11. The alignment fixture 3 includes two opposing fixture fixing plates 32, which are movably connected to the alignment platform 11. An alignment position is formed between the two fixture fixing plates 32, allowing the battery cell assembly 7 to be directly placed in this position, with the battery cell assembly 7 positioned vertically.

[0021] In order to achieve the movable connection between the fixture fixing plate 32 and the straightening platform 11, the straightening fixture 3 also includes two fixture moving plates 33. The two fixture fixing plates 32 are respectively connected to the two fixture moving plates 33 by screws, and the two fixture moving plates 33 are respectively movably connected to the straightening platform 11.

[0022] To achieve the movable connection between the fixture moving plate 33 and the alignment platform 11, an adjustment groove 331 is provided on the fixture moving plate 33 along its width direction. Multiple adjustment holes are provided on the alignment platform 11 along its width direction. Bolts can be installed in the adjustment grooves 331. After the fixture moving plate 33 moves to the predetermined position, the bolts are inserted into the corresponding adjustment holes and then secured with nuts. Removing the bolts from the adjustment holes allows for position adjustment of the fixture moving plate 33.

[0023] This application allows for the adjustment of the width of the alignment position by movably connecting the fixture moving plate 33 and the alignment platform 11, thus making it suitable for use with battery cell assemblies 7 of different thicknesses and having a wide range of applications.

[0024] like Figure 4As shown, after the battery cell assembly 7 is placed in the aligning position, to prevent the battery cells from tipping over, the clamp fixing plate 32 of this application has two upwardly protruding clamp support portions 321 at each end. The clamp support portions 321 and the clamp fixing plate 32 can be integrally formed. After the battery cell assembly 7 is placed in the aligning position, the clamp support portions 321 can support the battery cell assembly 7 and prevent the battery cells from tipping over.

[0025] During transportation, the solar cell assembly 7 may experience cell breakage, resulting in cell fragments. To prevent these fragments from affecting the overall alignment accuracy of the solar cell assembly 7, multiple perforated slots are formed on the alignment platform 11 along its length. After the solar cell assembly 7 is loosened by the upper air blower 24, the cell fragments can fall through the perforated slots to the lower platform or the lower conveyor line, etc.

[0026] In one embodiment, both the corrective lifting component 21 and the upper corrective lateral movement component 22 can be existing linear modules. Specifically, they can be commercially available ball screw linear modules.

[0027] As shown in Figure 3, the upper alignment component 23 includes an upper fixed bracket 232, which is slidably connected to the alignment lifting component 21. There are three upper alignment grippers 231, all fixed to the upper fixed bracket 232 and spaced apart. An upper alignment sponge pad 233 is fixed to each upper alignment gripper 231, and can be attached by adhesive. When aligning the battery cell assembly 7, the upper alignment sponge pad 233 contacts the battery cell assembly 7, flexibly compressing it to align it in the correct position.

[0028] To disperse the battery cells, the upper air blowing assembly 24 includes upper air blades 242, which are fixed to the upper fixed bracket 232. An upper air outlet 241 is disposed on the upper air blades 242. There are three upper air blades 242, each fixed to the upper fixed bracket 232 by screws. Three upper straightening grippers 231 are connected to the three upper air blades 242 by screws. The upper air blades 242 are connected to an external air source. Compressed air enters the upper air blades 242 and is blown out at high speed from the upper air outlet 241 as a thin sheet of air with a thickness of only 0.05 mm, thereby loosening the battery cell assembly 7.

[0029] After the solar cell assembly 7 is aligned by the upper alignment mechanism 2, the left and right sides of the solar cell assembly 7 also need to be aligned. Therefore, as Figure 1As shown, the cell alignment device also includes a left alignment mechanism 4 and a right alignment mechanism 5. The left alignment mechanism 4 is located on the left side of the alignment fixture 3, and the right alignment mechanism 5 is located on the right side of the alignment fixture 3. The left alignment mechanism 4 aligns the left side of the cell assembly 7, and the right alignment mechanism 5 aligns the right side of the cell assembly 7.

[0030] Specifically, such as Figure 1 , Figure 2 As shown, the left alignment mechanism 4 includes a left lateral movement component 41, a left longitudinal movement component 42, and a left alignment component 43. The left longitudinal movement component 42 is slidably connected to the left lateral movement component 41, and the left alignment component 43 is slidably connected to the left longitudinal movement component 42. The left alignment component 43 is provided with a left alignment gripper 431.

[0031] Preferably, the left lateral movement component 41 is an existing linear module. For example... Figure 2 As shown, the left longitudinal movement assembly 42 includes a left longitudinal fixed bracket 421 and a left longitudinal cylinder 422. The left longitudinal fixed bracket 421 is slidably connected to the left lateral movement assembly 41, and the left longitudinal cylinder 422 is fixed to the left longitudinal fixed bracket 421 by screws. The left alignment assembly 43 also includes a left alignment bracket 432, which is connected to the output end of the left longitudinal cylinder 422 by screws or the like. The left lateral movement assembly 41 drives the left longitudinal fixed bracket 421 to move in the lateral direction, and the left longitudinal cylinder 422 drives the left alignment bracket 432 to move in the longitudinal direction.

[0032] There are three left-aligning grippers 431, which are fixed to the left-aligning bracket 432 by screws, and the three left-aligning grippers 431 are spaced apart. Left-aligning sponge pads 433 can also be fixed to the left-aligning grippers 431 by means of adhesive or other methods.

[0033] In one embodiment, such as Figure 1 , Figure 2 As shown, the left alignment mechanism 4 also includes a left air blowing assembly 44, which includes a left air blade 441. The left air blade 441 is fixed to the left alignment bracket 432 by screws, and the left air blade 441 has multiple left air blowing ports 442. Preferably, the number of left air blades 441 is also three.

[0034] The right alignment mechanism 5 includes a right lateral movement component 51, a right longitudinal movement component 52, and a right alignment component 53. The right longitudinal movement component 52 is slidably connected to the right lateral movement component 51, and the right alignment component 53 is slidably connected to the right longitudinal movement component 52. The right alignment component 53 is provided with a right alignment gripper 531.

[0035] Preferably, the right lateral movement component 51 can be a linear module currently used in the market. The right longitudinal movement component 52 includes a right longitudinal fixing bracket 521 and a right longitudinal cylinder 522. The right longitudinal fixing bracket 521 is slidably connected to the right lateral movement component 51, and the right longitudinal cylinder 522 is fixed to the right longitudinal fixing bracket 521 by screws.

[0036] like Figure 2 As shown, the right alignment component 53 includes a right alignment bracket 532, which is connected to the output end of the right longitudinal cylinder 522 by screws. There are three right alignment grippers 531, all of which are fixed to the right alignment bracket 532 by screws. The three right alignment grippers 531 are spaced apart, and right alignment sponge pads 533 can be attached to each right alignment gripper 531 by adhesive. The right lateral movement component 51 moves the right alignment grippers 531 laterally, and the right longitudinal cylinder 522 moves the right alignment grippers 531 longitudinally.

[0037] In one embodiment, the right alignment mechanism 5 further includes a right air blowing assembly 54, which includes a right air blade 541. The right air blade 541 can be fixed to the right alignment bracket 532 by screws, and the right air blade 541 has multiple right air blowing ports 542. Preferably, the number of right air blades 541 is also three.

[0038] Because of the presence of an upper air blade 242, a left air blade 441, and a right air blade 541, air can be blown from the top, left, and right sides of the battery cell assembly 7, thereby loosening the battery cell assembly 7. In one embodiment, to achieve better results, a lower air outlet can also be provided on the alignment platform 11, and the lower air outlet and the upper air outlet 241 are staggered.

[0039] Specifically, a lower air blade can be installed on the alignment platform 11 by screws, with the lower air outlet located on the lower air blade. To avoid affecting the placement of the battery cell assembly 7 on the alignment platform 11, the lower air outlet of the lower air blade can be located inside a slot. Preferably, there can be two lower air blades.

[0040] In one embodiment, a sensor 6 may also be installed on the alignment platform 11. The sensor 6 may be a photoelectric sensor or a fiber optic sensor, and the front and back of the battery cell are determined by the detection of the sensor 6.

[0041] In use, the cell alignment device of this application first places the cell assembly 7, composed of multiple stacked cells, in the alignment position. At this time, the bottom of the cell assembly 7 is located on the alignment platform 11, which provides a horizontal reference plane. Then, the upper alignment horizontal movement component 22 moves the upper air blade 242 above the cell assembly 7, the left vertical movement component 42 moves the left air blade 441 to the left side of the cell assembly 7, and the right vertical movement component 52 moves the right air blade 541 to the right side of the cell assembly 7. The upper air blade 242, lower air blade, left air blade 441, and right air blade 541 loosen the cell assembly 7, and the cell fragments fall through the slots. Then, the upper alignment gripper 231 aligns the cell assembly 7, and the left and right sides of the cell assembly 7 are aligned by the left alignment gripper 431 and right alignment gripper 531, thereby completing the alignment of the cell assembly 7.

[0042] The alignment device for the solar cells in this application aligns the solar cell assembly 7 by gently squeezing the solar cells with a sponge pad during alignment. A sponge pad of suitable hardness can be selected based on needs or limited experimental requirements. The left air outlet 442 and the right air outlet 542 can also be arranged alternately. The upper air knife 242, lower air knife, left air knife 441, and right air knife can all be commercially available air knives, which can supply compressed air to the air knives, thus blowing the air out.
