[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 Figure 1 , Figure 2 As shown in the figure, this application embodiment provides a battery cell unpacking module, including a gantry frame 1, a straightening mechanism 2, and two robots 3. A conveyor line 4 for transporting packaging boxes 5 passes through the inside of the gantry frame 1. The straightening mechanism 2 includes two straightening components 21, both of which are fixed to the gantry frame 1 and are arranged opposite each other on both sides of the conveyor line 4. The packaging boxes 5 are straightened by the two straightening components 21. Both robots 3 are connected to the gantry frame 1, arranged opposite each other, and each robot 3 is equipped with a cutter 6.

[0019] The battery cell unpacking module of this embodiment includes a gantry frame 1, a straightening mechanism 2, and two robots 3, each equipped with a cutter 6. In use, the packaging box 5 is first conveyed to a predetermined position by a conveyor line 4. Then, the two straightening components 21 straighten the packaging box 5. Finally, the two robots 3 move the cutter 6 to cut the sealing tape on the packaging box 5. This battery cell unpacking module can automatically open the packaging box 5, achieving a high degree of automation, saving labor costs, and improving work efficiency.

[0020] In one embodiment, the conveyor line 4 can be an existing ordinary conveyor line. The conveyor line 4 can be driven by a motor to move the conveyor belt and place the packaging box 5 on the conveyor belt, thereby realizing the conveying of the packaging box 5 on the conveyor belt.

[0021] like Figure 4 , Figure 5 As shown, after the packaging box 5 is conveyed to the predetermined position via the conveyor line 4, it is first aligned by two alignment components 21 to ensure it is in the correct position. To achieve alignment of the packaging box 5, the alignment component 21 includes an alignment drive 211, an alignment screw 212, and an alignment plate 213. Specifically, the alignment component 21 also includes an alignment fixing plate 214 and an alignment connecting plate 215. The alignment fixing plate 214 is fixed to the gantry frame 1 with screws. The alignment drive 211 is a servo motor, which is fixed to one end of the alignment fixing plate 214 with screws. The drive shaft of the servo motor is connected to the alignment screw 212, which can be an existing ball screw. The ball screw can be rotatably connected to the alignment fixing plate 214 via bearings or other components. The alignment connecting plate 215 is connected to the screw nut of the ball screw, and the alignment plate 213 is connected to the alignment connecting plate 215 with screws. When the servo motor drives the ball screw to rotate, the ball screw can drive the alignment connecting plate 215 and the alignment plate 213 to move closer to or further away from the conveyor line 4 through the screw nut.

[0022] In one embodiment, a slide rail 216 is also fixed on the straightening fixing plate 214. The slide rail 216 and the straightening fixing plate 214 can also be fixed with screws. The straightening connecting plate 215 is slidably connected to the slide rail 216 by a slider.

[0023] After the conveyor line 4 transports the packaging box 5 to the predetermined position, the conveyor line 4 stops transporting. Then, the correction drive 211 of the two correction components 21 is activated. The correction drive 211 drives the correction screw 212 to rotate. During the rotation, the correction screw 212 drives the correction plate 213 to move closer to the packaging box 5. The two correction plates 213 correct the packaging box 5. In this embodiment of the application, the packaging box 5 located on the conveyor line 4 can be corrected and positioned by setting the correction components 21.

[0024] In one embodiment, such as Figure 2 As shown, the correction mechanism 2 further includes two blocking components 22, both of which are fixed to the gantry frame 1 and are arranged opposite to each other on both sides of the conveyor line 4. Furthermore, the blocking components 22 and the correction component 21 are arranged sequentially along the conveying direction of the conveyor line 4.

[0025] like Figure 4 , Figure 5As shown, the blocking assembly 22 includes a blocking cylinder 221 and a baffle 222. The blocking cylinder 221 is fixed to the gantry frame 1 by bolts. The piston rod of the blocking cylinder 221 is connected to the baffle 222, and the blocking cylinder 221 drives the baffle 222 to move closer to or further away from the conveyor line 4. The baffle 222 and the piston rod of the blocking cylinder 221 can also be fixed together by bolts. When the packaging box 5 moves to the predetermined position, the blocking cylinder 221 first drives the baffle 222 to move, so that the baffle 222 touches the packaging box 5.

[0026] The correction mechanism 2 also includes two sensor assemblies, which are respectively disposed on the two blocking assemblies 22. Further, each sensor assembly includes a transmitter 23 and a receiver 24. The transmitter 23 can be bolted to the blocking cylinder 221, and the receiver 24 can be bolted to the baffle 222. The receiver 24 is capable of receiving the signal emitted by the transmitter 23 and reflected by the packaging box 5.

[0027] Specifically, the aforementioned sensor assembly can be an existing reflective photoelectric sensor. The transmitter 23 emits a beam of light (infrared light). When this beam of light shines on the packaging box 5, it is reflected by the packaging box 5, and the reflected light is received by the receiver 24, thereby triggering a signal. When the trigger signal is received, the correction drive 211 is activated, driving the correction plate 213 to move and correct the packaging box 5.

[0028] To ensure the reliability of the sensor, a sensor component with appropriate sensitivity can be selected according to the packaging box 5 used, thereby ensuring the reflection and reception of the light beam.

[0029] In one embodiment, the correction mechanism 2 includes a sensor assembly comprising a transmitter 23 and a receiver 24, which are respectively fixed to two baffles 222. When the receiver 24 fails to receive a signal from the transmitter 23, it triggers the start of the correction drive 211. The sensor assembly is a photoelectric sensor.

[0030] The packaging box 5 can be an existing paper or plastic packaging box used for packaging battery cells. After the battery cells are packaged, the packaging box 5 is sealed with tape (transparent tape or sealing tape). In this embodiment, two robots 3 drive a cutter 6 to cut the tape, thereby opening the packaging box 5.

[0031] Specifically, both robots 3 are existing six-axis robots, enabling them to drive the cutter 6 to move flexibly in three-dimensional space. Both robots 3 can be fixed to the gantry 1 with bolts. In other embodiments, the robots 3 can also be fixed to the gantry 1 in other ways, as long as fixing is possible, the specific fixing method is not limited.

[0032] The aforementioned cutter 6 can be a standard blade used for cutting tape. To achieve the connection and fixation between the cutter 6 and the robot 3, as follows: Figure 3 As shown, a connecting plate 10 is connected to the robot 3, and the cutter 6 is fixed to one end of the connecting plate 10. The connecting plate 10 and the robot 3 can be connected by screws.

[0033] In order to connect the cutter 6 and the connecting plate 10, a cutter fixing component 7 is fixed to one end of the connecting plate 10, and the cutter 6 is fixed to the cutter fixing component 7.

[0034] Specifically, such as Figure 2 , Figure 3 As shown, the cutter fixing assembly 7 includes a cutter fixing plate 71 and a cutter fixing block 72. The cutter fixing plate 71 is fixed to one end of the connecting plate 10 by screws, and the cutter fixing block 72 is connected to the cutter fixing plate 71 by bolts. The cutter 6 is fixed to the cutter fixing block 72. Specifically, the cutter 6 can be fixed to the cutter fixing block 72 by screws. In other embodiments, a fixing groove can be provided on the cutter 6, and a fixing protrusion matching the fixing groove can be provided on the cutter fixing block 72. The cutter 6 is fixed to the cutter fixing block 72 through the fixing groove and the fixing protrusion. The cutter 6 can not only cut the tape on the packaging box 5, but also cut the plastic film bag inside the packaging box 5.

[0035] In one embodiment, to enable the opening of the packaging box 5, the battery cell opening module further includes two vacuum suction cups 8, which are respectively connected to two robots 3. Specifically, the vacuum suction cups 8 and the cutter 6 are respectively fixed to opposite ends of the connecting plate 10. The other end of the connecting plate 10 is connected to a suction cup connecting plate 9 by screws, and the vacuum suction cups 8 and the suction cup connecting plate 9 can be connected by threads and fixed by nuts. The vacuum suction cups 8 achieve adsorption through the principle of vacuum adsorption.

[0036] The working principle of the unpacking module for the battery cells in this embodiment is as follows: First, the conveyor line 4 transports the packaging box 5 to a predetermined position. Then, the blocking cylinder 221 moves the baffle 222, causing it to contact the packaging box 5. The transmitter 23 of the sensor assembly emits a light beam, which is reflected by the packaging box 5 and received by the receiver 24, triggering a signal. Next, the correction drive 211 drives the correction screw 212 to rotate, which in turn moves the correction plate 213, thereby correcting the packaging box 5.

[0037] Then, the two robots 3 drive the cutter 6 to move, cutting the tape on the packaging box 5 (the tape pasted at both ends of the packaging box 5, and the tape pasted along the length of the packaging box 5). At this point, all the tape used to attach the four lids on the packaging box 5 is cut off (the four lids refer to the two lids at the front and rear ends, and the two lids on the left and right sides). Next, the two robots 3 drive the two vacuum suction cups 8 to move, first lifting and pressing down the two lids on the left and right ends, and then lifting and pressing down the two lids at the front and rear ends. Finally, the two robots 3 drive the two cutters 6 to move along the four edges of the plastic film bag to cut the plastic film bag. After the operation is completed, the alignment component 21 returns to its original position, and the conveyor line 4 moves the packaging box 5 to the next process.

[0038] The battery cell unpacking module of this application embodiment can automatically open the packaging box 5 and cut the plastic film bag without human intervention, reducing labor costs and improving work efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0040] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this application, and these should all be included within the scope of protection of this application.
