Description

Technical Field

[0001] This utility model relates to the technical field of tape application mechanisms, and in particular to a tape application mechanism for back contact battery cells. Background Technology

[0002] BC solar cells, short for back-contact solar cells, are based on the principle of transferring all the electrode grid lines from the front of the cell to the back. The PN junction and metal contacts are located on the back of the cell and arranged in an interdigitated pattern. This structure ensures that the front surface of the cell is free of any grid lines obstructing the light, maximizing the utilization of incident light, reducing optical losses, and resulting in a larger effective power generation area. The exposed solder ribbons at the cell connections are vulnerable to damage during production and use, and also negatively impact the overall aesthetics of the cell. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to solve the problem that the welding strip at the connection of the existing battery cell is exposed, which will be contacted during the production process or use, causing damage to the welding strip, and the exposed welding strip affects the overall aesthetics of the battery cell. A back contact battery cell adhesive tape applicator is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a back contact battery cell adhesive tape applicator, comprising:

[0005] A rotating module on which battery cells can be placed and fixed, the rotating module being used to switch the battery cells between a feeding station, an adhesive application station and a discharging station;

[0006] The adhesive applicator is located on one side of the rotating module and is used to apply adhesive tape to the battery cells at the adhesive application station. The adhesive applicator includes a frame, on which a front clamping mechanism and a rear clamping mechanism are slidably disposed. The front clamping mechanism is used to clamp the front end of the adhesive tape, and the rear clamping mechanism is used to clamp the rear end of the adhesive tape. The rear clamping mechanism is provided with a cutting mechanism for cutting the adhesive tape. The frame is provided with a control mechanism for controlling the front clamping mechanism to move closer to or away from the rear clamping mechanism. The frame is provided with a locking mechanism for locking the rear clamping mechanism to the frame. The frame is provided with a first drive mechanism for controlling the front clamping mechanism to move closer to or away from the battery cells, and a second drive mechanism for controlling the rear clamping mechanism to move closer to or away from the battery cells. Compared to existing technologies, this solution uses a rotating module to process battery cells, switching between the loading station, the adhesive application station, and the unloading station. When the battery cell is displacing and applying adhesive, the adhesive application mechanism works in coordination with the front clamping mechanism, the rear clamping mechanism, the cutting mechanism, the control mechanism, the first drive mechanism, and the second drive mechanism to clamp, apply, and cut the adhesive tape, thus achieving adhesive application to the solder ribbon on the battery cell. This ensures that the solder ribbon is not exposed, preventing damage caused by accidental contact with the solder ribbon and maintaining the overall aesthetics of the battery cell.

[0007] To implement the front clamping mechanism, in some preferred embodiments, the front clamping mechanism includes two opposing front grippers, and a third drive mechanism is disposed between the two front grippers for driving the two front grippers closer or further apart. The third drive mechanism controls the two opposing front grippers to move closer or further apart, thereby achieving clamping or releasing of the front grippers.

[0008] To implement the rear clamping mechanism, in some preferred embodiments, the rear clamping mechanism includes two opposing rear grippers, and a fourth drive mechanism is disposed between the two rear grippers to drive the two rear grippers closer or further apart. The fourth drive mechanism controls the two opposing rear grippers to move closer or further apart, thereby achieving clamping or releasing of the rear grippers.

[0009] To implement the cutting mechanism, in some preferred embodiments, the cutting mechanism includes a cutter, and a fifth driving mechanism is provided on the rear clamping mechanism. The fifth driving mechanism is used to drive the cutter to cut the tape. The fifth driving mechanism drives the cutter to approach the tape and cut the tape.

[0010] To implement the control mechanism, in some preferred embodiments, the control mechanism includes a sixth drive mechanism fixedly mounted on the frame, and the sixth drive mechanism and the front clamping mechanism are mutually connected through a synchronous belt pulley mechanism.

[0011] In order to enable the front clamping mechanism and the rear clamping mechanism to slide on the frame, in some preferred embodiments, the frame is provided with a linear guide rail, the front clamping mechanism is provided with a first slider, and the rear clamping mechanism is provided with a second slider. The first slider and the second slider are both matched with the linear guide rail, and the first slider and the second slider are slidably mounted on the linear guide rail.

[0012] In order to realize the rotating module, in some preferred embodiments, the rotating module includes a rotating platform and a seventh driving mechanism for driving the rotating platform to rotate, wherein at least three negative pressure adsorption platforms for placing battery cells are evenly distributed along the circumferential direction on the rotating platform.

[0013] In order to unwind the tape, some preferred embodiments further include an unwinding mechanism disposed on the frame and used for actively unwinding the tape.

[0014] In some preferred embodiments, the unwinding mechanism includes an unwinding wheel rotatably mounted on a frame for storing the tape, an unwinding drive mechanism for driving the unwinding wheel to rotate on the frame, a plurality of guide wheels for winding and guiding the tape on the frame, and a tensioning wheel for tensioning the tape slidably mounted on the frame, the tensioning wheel being located between the plurality of guide wheels.

[0015] In some preferred embodiments, the unwinding drive mechanism includes an unwinding motor, which is fixedly mounted on the frame, and the unwinding motor and the unwinding wheel are connected to each other via a belt pulley mechanism.

[0016] The beneficial effects of this utility model are as follows: When using the back contact battery cell adhesive tape application mechanism of this utility model, the battery cell is processed by rotating the module and switching between the feeding station, adhesive application station, and discharge station. When the battery cell is displacing and applying adhesive tape, the adhesive application mechanism completes the clamping, application, and cutting of the adhesive tape through the cooperation of the front clamping mechanism, the rear clamping mechanism, the cutting mechanism, the control mechanism, the first driving mechanism, and the second driving mechanism. This achieves the application of adhesive tape to the solder ribbon on the battery cell, ensuring that the solder ribbon is not exposed. This prevents damage caused by accidental contact with the solder ribbon and ensures the overall aesthetics of the battery cell. It avoids the problem that the solder ribbon at the connection point of the existing battery cell is exposed, which on the one hand, will come into contact with it during production or use, causing damage to the solder ribbon, and on the other hand, the exposed solder ribbon affects the overall aesthetics of the battery cell.

[0032] like Figure 1-8 As shown, a back contact battery cell tape application mechanism includes:

[0033] Rotating module 1, on which battery cells can be placed and fixed, is used to switch the battery cells between the feeding station, the adhesive application station and the unloading station.

The rear clamping mechanism 203 is provided with a cutting mechanism 204 for cutting the adhesive tape. The frame 201 is provided with a control mechanism for the front clamping mechanism.

[0035] The front clamping mechanism 202 includes two opposing front grippers 2021, with a third drive mechanism 2022 positioned between them for driving the two grippers 2021 to move closer or further apart. The rear clamping mechanism 203 includes two opposing rear grippers 2031, with a fourth drive mechanism 2032 positioned between them for driving the two rear grippers 2031 to move closer or further apart. The cutting mechanism 204 includes a cutter 2041. The rear clamping mechanism 203 is equipped with... A fifth drive mechanism 2042 is provided, which is used to drive the cutter 2041 to cut the tape. The control mechanism 205 includes a sixth drive mechanism fixedly installed on the frame 201. The sixth drive mechanism and the front clamping mechanism 202 are connected to each other through a synchronous belt pulley mechanism. The rotating module 1 includes a rotating platform 101 and a seventh drive mechanism 102 for driving the rotating platform 101 to rotate. Four negative pressure adsorption platforms 103 for placing battery cells are evenly distributed along the circumferential direction on the rotating platform 101.

[0036] In this embodiment, the first drive mechanism 206, the second drive mechanism 207, the third drive mechanism 2022, the fourth drive mechanism 2032, and the fifth drive mechanism 2042 are all cylinders, the sixth drive mechanism and the seventh drive mechanism 102 are both servo motors, and the locking mechanism is a guide rail lock.

[0037] A linear guide rail is provided on the frame 201, a first slider is provided on the front clamping mechanism 202, and a second slider is provided on the rear clamping mechanism 203. Both the first slider and the second slider are matched with the linear guide rail and are slidably mounted on the linear guide rail, so that both the front clamping mechanism 202 and the rear clamping mechanism 203 can slide on the frame 201.

[0038] It also includes an unwinding mechanism 208 mounted on the frame 201 for actively unwinding the tape. The unwinding mechanism 208 includes an unwinding wheel 2081 rotatably mounted on the frame 201 for storing the tape. The frame 201 is provided with an unwinding drive mechanism 2082 for driving the unwinding wheel 2081 to rotate. The frame 201 is provided with two guide wheels 2083 for winding and guiding the tape. The frame 201 is slidably provided with a tensioning wheel 2084 for tensioning the tape. The frame 201 is also provided with a second linear guide rail. The tensioning wheel 2084 is provided with a slider that matches the second linear guide rail. The slider slides on the second linear guide rail. The tensioning wheel 2084 is located between the two guide wheels 2083. The unwinding drive mechanism 2082 includes an unwinding motor, which is fixedly mounted on the frame 201. The unwinding motor and the unwinding wheel 2081 are connected to each other through a belt pulley mechanism.

[0039] When using the aforementioned back-contact battery cell tape application mechanism, the BC battery cells to be tapered are first loaded onto the loading station of the rotating module 1. The BC battery cells are placed on the negative pressure adsorption table 103 and fixed by negative pressure adsorption. Then, the servo motor at the seventh drive mechanism 102 drives the rotating table to rotate, and the loading station can continue to load until the BC battery cells are brought to the tape application station. At this time, the rotating module 1 stops running, and the tape application mechanism 2 is started. The unwinding wheel 2081 of the unwinding mechanism 208 has tape on it, and the tape passes around the first guide in sequence. The tape passes through the pulley 2083, tension pulley 2084, and second guide pulley 2083, then through the two rear grippers 2031 of the rear gripping assembly. The servo motor at the sixth drive mechanism of the control mechanism 205 drives the synchronous pulley to rotate forward, causing the front gripping assembly to slide on the frame 201 and gradually move closer to the rear gripping assembly. The cylinder at the third drive mechanism 2022 then drives the two front grippers 2021 to clamp the front end of the tape. Finally, the cylinder at the fourth drive mechanism 2032 controls the two rear grippers 2031 to loosen the tape. The tape is detached, and then the servo motor at the sixth drive mechanism of control mechanism 205 drives the synchronous pulley to reverse, causing the front clamping component to slide on the frame 201 and gradually move away from the rear clamping component until the front clamping component is moved to the desired position. Then, the cylinder at the fourth drive mechanism 2032 controls the two rear grippers 2031 to clamp the tape. The cylinders at the first drive mechanism 206 and the second drive mechanism 207 simultaneously drive the front clamping mechanism 202 and the rear clamping mechanism 203 to move downward, causing the tape to adhere to the BC battery cell. On the side of the welding strip, the fifth drive mechanism 2042 at the cutting mechanism 204 is controlled. The cylinder at the fifth drive mechanism 2042 drives the cutter 2041 to descend and cut the tape. After the tape is cut, the front clamping assembly is controlled to release the front end of the tape, and the various parts of the adhesive applicator 2 are restored to their initial positions to complete the adhesive applicator work of the BC battery cell. The rotating module 1 rotates the adhesive applicator BC battery cell to the unloading station, and at the same time, the next BC battery cell is moved to the adhesive applicator station. The adhesive applicator process is repeated according to the above steps.

[0040] The above description, based on the preferred embodiments of this utility model, provides inspiration. Those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification but must be determined according to the claims.
