[0043] To solve the problem that the battery cell may fall from the discharging end of the conveyor belt in the related art, which causes potential safety hazards, a battery cell anti-falling device is provided. Referring to Figure 1 and Figure 2 , an embodiment of the present application provides a battery cell anti-falling device, which is applicable to the conveyance during the processing of the battery cell 400. The battery cell anti-falling device includes a frame 100, a conveying assembly 200 and a sensing assembly 300. The conveying assembly 200 is disposed on the frame 100. The conveying assembly 200 is used to convey the battery cell 400 and define the movement of the battery cell 400 in the conveying direction of the battery cell 400. The sensing assembly 300 is disposed at the discharging end of the frame 100. The sensing assembly 300 is used to generate a detection signal when detecting that the battery cell 400 passes by. The conveying assembly 200 is configured to stop conveying the battery cell 400 according to the detection signal.

[0044] Specifically, in this embodiment, the conveying direction of the battery cell 400 is parallel to the length direction of the frame 100. The discharging end of the frame 100 is also the discharging end of the conveying assembly 200. The sensing assembly 300 is disposed at the discharging end of the conveying assembly 200. The setting of the discharging end of the frame 100 can be determined according to the actual processing requirements of the battery cell 400, that is, the discharging end of the frame 100 can be any one of the two ends in the length direction of the frame 100, so as to improve the overall adaptability of the device. Correspondingly, the position setting of the sensing assembly 300 changes with the change of the position of the discharging end of the frame 100. In addition, in other embodiments, sensing assemblies 300 can also be disposed at both ends of the frame 100. When the discharging end of the frame 100 is determined, the corresponding sensing assembly 300 can be activated.

[0045] During the process of conveying the battery cell 400 in this embodiment, when a manipulator operation error occurs and the processed battery cell 400 is not taken away from the conveying component 200 in time, the battery cell 400 will continue to move towards the discharging end of the conveying component 200 along with the conveying component 200 and gradually approach the sensing component 300. When the sensing component 300 detects the battery cell 400, it immediately sends a detection signal to the conveying component 200 to stop the conveying of the conveying component 200, thereby avoiding the situation that the battery cell 400 drops after reaching the discharging end of the conveying component 200, and further ensuring the safety and stability of the conveying process of the battery cell 400.

[0046] Referring to Figure 1 and Figure 2 , in some embodiments, the conveying component 200 includes two roller shafts 210, a conveyor belt 220, a plurality of loading fixtures 230, and a driving member 240. One of the roller shafts 210 is rotatably arranged at one end of the frame 100, and the other roller shaft 210 is rotatably arranged at the other end of the frame 100. The conveyor belt 220 is wound around the two roller shafts 210 along the length direction of the frame 100; a plurality of loading fixtures 230 are evenly distributed on the conveyor belt 220 along the length direction of the frame 100. The loading fixtures 230 are used to receive the battery cell 400 and limit the movement of the battery cell 400 in the conveying direction of the battery cell 400; the driving member 240 is used to drive the roller shaft 210 to rotate.

[0047] Wherein, the distance between two adjacent loading fixtures 230 is fixed, so that the manipulator adapted to this battery cell anti-drop device can stably and orderly grab the battery cell 400 on the loading fixture 230, thereby ensuring the stability of the processing process of the battery cell 400. The driving member 240 includes a driving motor, and the driving motor is fixedly connected to the outer side wall of the end of the frame 100, and the motor shaft of the driving motor is coaxially and fixedly connected to one end of the closer roller shaft 210.

[0048] Specifically, after the battery cell 400 is stably placed on the loading fixture 230, the driving motor is used to drive the roller shaft 210 to rotate, so that the roller shaft 210 drives the conveyor belt 220 to rotate, and the conveyor belt 220 drives the loading fixture 230 to move towards the end of the frame 100, thereby realizing the stable conveying of the battery cell 400.

[0049] In this embodiment, through the cooperation of the driving motor, the roller shaft 210, the conveyor belt 220, and the loading fixture 230, it is helpful to realize the stable conveying of the battery cell 400, and the structure is simple and easy to control.

[0050] Referring to Figure 2 and Figure 3, in some embodiments, the sensing component 300 includes a support sheet 310 and a sensor 320. The support sheet 310 is disposed on one side of the frame 100 in the conveying direction of the battery cell 400, and one end of the support sheet 310 is connected to the frame 100; the sensor 320 is disposed at the end of the support sheet 310 away from the frame 100, and the height of the sensor 320 is higher than the height of the carrying tooling 230.

[0051] Wherein, the support sheet 310 is bent, a kidney-shaped hole 312 is provided on the side wall of the bottom end of the support sheet 310, the side wall of the bottom end of the support sheet 310 abuts against the outer side wall of the frame 100, the top end of the support sheet 310 extends vertically upward, the bent part of the support sheet 310 abuts against the top wall of the frame 100, and the sensor 320 is detachably disposed at the top end of the support sheet 310 by means of cooperation such as bolts and nuts. The height of the sensor 320 is higher than the height of the carrying tooling 230, and the sensor 320 faces the battery cell 400 and the conveyor belt 220 to prevent the sensor 320 from misjudging the carrying tooling 230.

[0052] Specifically, the sensor 320 is a normally closed sensor 320 and is connected in series to the emergency stop circuit of the drive motor controller, so that the normally closed sensor 320 is disconnected when detecting that a battery cell 400 passes by, thereby disconnecting the emergency stop circuit of the drive motor controller to achieve the emergency stop of the drive motor, so as to timely avoid the falling of the battery cell 400. In addition, the distance between the installation position of the sensor 320 and the discharging end of the conveyor belt 220 is greater than or equal to one battery cell 400, so as to reserve a section of distance for the battery cell 400 running to the end of the conveyor belt 220 and avoid the risk of the battery cell 400 falling from the conveyor belt 220 due to untimely stop of the conveyor belt 220.

[0053] In this embodiment, the normally closed sensor 320 with a height sufficient to face the battery cell 400 is used to sense and monitor the position of the battery cell 400, which can avoid the occurrence of accidents of the battery cell 400 falling due to program loopholes or function shielding, thereby ensuring the reliability and stability of the battery cell anti-falling device during use.

[0054] Refer to Figure 2 and Figure 3 , in some embodiments, a plurality of installation positions 110 are provided on the side wall of the discharging end of the frame 100, and the support sheet 310 is detachably connected to the installation positions 110 to adjust the height of the sensor 320.

[0055] Wherein, the installation positions 110 are installation holes, and a plurality of installation holes are arranged on the side wall of the end of the frame 100 in the vertical direction.

[0056] Specifically, since the thickness of the battery cells 400 in different batches is inconsistent, when the battery cells 400 are placed flat on the loading tool 230, the heights of the battery cells 400 protruding from the loading tool are inconsistent. In order to ensure that the sensor 320 can face the battery cell 400 to accurately monitor the conveying position of the battery cell 400, a plurality of mounting holes with different heights are provided so that workers can adaptively adjust the height of the support piece 310 protruding from the top wall of the frame 100 according to the thickness of the battery cell 400, thereby realizing the adaptive adjustment of the height of the sensor 320. When adjusting the height of the support piece 310, workers can achieve the detachable connection between the support piece 310 and each mounting position 110 through the cooperation of bolts, nuts, the mounting position 110 and the kidney-shaped hole 312.

[0057] In this embodiment, through the cooperation of bolts, nuts, the mounting position 110 and the kidney-shaped hole 312, the detachable connection between the support piece 310 and each mounting position 110 can be realized, so as to realize the adjustable height of the support piece 310, and further enable the sensor 320 to adapt to the position monitoring of battery cells 400 with different thicknesses, which helps to improve the adaptability of the battery cell anti-falling device.

[0058] Refer to Figure 2 and Figure 3 In some embodiments, the loading tool 230 includes a receiving block 231 and an abutting member. The receiving block 231 is arranged on the conveyor belt 220, and the receiving block 231 is used for receiving the battery cell 400; the abutting member is arranged on the conveyor belt 220, and the abutting member is used for abutting against the battery cell 400 along the conveying direction of the battery cell 400.

[0059] Among them, the length direction of the receiving block 231 is perpendicular to the conveying direction of the conveyor belt 220, and the bottom wall of the receiving block 231 is fixedly connected to the conveyor belt 220. The abutting member is also fixedly connected to the conveyor belt 220.

[0060] Specifically, when conveying the battery cell 400, that is, when loading from the starting end of the conveyor belt 220, the larger side surface of the battery cell 400 is stably placed on the upper surface of the receiving block 231, and then the abutting member is used to abut against the battery cell 400, so that the battery cell 400 is limited in its own conveying direction, which helps to ensure the stability of the battery cell 400 during conveying; and it helps to avoid the possibility of relative sliding between the battery cell 400 and the conveyor belt 220 under the action of inertia after the sensor 320 controls the driving motor to stop working, thereby ensuring the stability of the battery cell 400 during conveying.

[0061] Refer to Figure 2 and Figure 3, in some embodiments, the abutting member includes two abutting blocks 234, an abutting plate 235, and a locking member. The two abutting blocks 234 are respectively arranged on both sides of the receiving block 231 along the conveying direction of the battery cell 400; the abutting plate 235 is slidably arranged on the abutting block 234, and the sliding direction of the abutting plate 235 is the same as the conveying direction of the battery cell 400; the locking member is used to limit the abutting plate 235 on the abutting block 234, so that the two abutting plates 235 abut against the battery cell 400 along the conveying direction of the battery cell 400.

[0062] Among them, the two abutting blocks 234 are symmetrically arranged on both sides of the receiving block 231 with respect to the receiving block 231. A limiting sliding groove 2340 is provided on the top wall of the abutting block 234, and the length direction of the limiting sliding groove 2340 is the same as the conveying direction of the battery cell 400. A plurality of limiting screw grooves 236 are provided on the bottom wall of the limiting sliding groove 2340 along its own length direction; the longitudinal section of the abutting plate 235 is T-shaped, the bottom end of the abutting plate 235 is slidably connected in the limiting sliding groove 2340, and a limiting block is fixedly connected to the side wall of the bottom end of the abutting plate 235; the locking member includes a locking bolt, and the locking end of the locking bolt penetrates through the top wall of the limiting block and is screwed tightly with the limiting screw groove 236.

[0063] Specifically, after the battery cell 400 is stably placed on the receiving block 231, slide the two abutting plates 235 to abut against the side wall of the battery cell 400, and realize the fixation of the abutting plate 235 through the cooperation of the locking bolt and the limiting screw groove 236; when the worker needs to adjust the position of the abutting plate 235 according to the width of the battery cell 400, that is, the width of one side of the battery cell 400 along the conveying direction, release the locking bolt and slide to adjust the position of the abutting plate 235 in the limiting sliding groove 2340.

[0064] In this embodiment, through the cooperation of the abutting block 234, the limiting sliding groove 2340 and the locking member, it is convenient for the worker to adaptively adjust the position of the abutting plate 235 according to the width of the battery cell 400, thereby helping to improve the adaptability of the battery cell anti-falling device.

[0065] Refer to Figure 2 and Figure 3 , in some embodiments, a clamping member for clamping the battery cell 400 is provided on the receiving block 231.

[0066] Specifically, although the battery cell 400 can be limited in the conveying direction of the battery cell 400 under the action of the abutting member, in order to further ensure the stable clamping effect of the carrying tooling 230 on the battery cell 400 in the horizontal direction, a clamping member is provided on the receiving block 231.

[0067] Refer to Figure 3, in some embodiments, the clamping member includes two clamping blocks 232 and a fixing member. The two clamping blocks 232 are both slidably arranged on the receiving block 231, and the sliding direction of the clamping blocks 232 is perpendicular to the conveying direction of the battery cell 400; the fixing member is used to limit the clamping blocks 232 on the receiving block 231 so that the two clamping blocks 232 abut against the battery cell 400 in a direction perpendicular to the conveying direction of the battery cell 400.

[0068] Among them, a guiding chute 2310 is provided on the upper surface of the receiving block 231 along its own length direction, that is, the length direction of the guiding chute 2310 is perpendicular to the conveying direction of the battery cell 400, and a plurality of locking screw grooves 233 are provided on the bottom wall of the guiding chute 2310 along its own length direction; the bottom end of the clamping block 232 is slidably connected in the guiding chute 2310, and a fixing block is fixedly connected to the side wall at the bottom end of the clamping block 232. The fixing member includes a limit bolt, and the locking end of the limit bolt is used to penetrate the top wall of the fixing block and be screwed tightly with the locking screw groove 233.

[0069] Specifically, after the battery cell 400 is placed on the receiving block 231, first slide the two clamping blocks 232 to abut against the two side walls of the battery cell 400 along its own conveying direction respectively, and then use the cooperation of the limit bolt and the locking screw groove 233 to fix the positions of the clamping blocks 232, so as to realize the stable limitation of the battery cell 400 in the horizontal direction in cooperation with the abutting member, thereby helping to ensure the stability of the battery cell 400 during the conveying process.

[0070] Refer to Figure 3 , in some embodiments, at least one auxiliary block 237 is further preset in the guiding chute 2310, and a notch 2311 communicating with the guiding chute 2310 is provided through the side wall of the receiving block 231.

[0071] Among them, the bottom end of the auxiliary block 237 is also slidably connected in the guiding chute 2310, a fixing block is also fixedly connected to the side wall at the bottom end of the auxiliary block 237, and the position of the auxiliary block 237 in the guiding chute 2310 can also be limited by the cooperation of the bolt and the locking screw groove 233.

[0072] Specifically, the positions of the auxiliary blocks 237 can be set in advance according to the specific sizes of several models of battery cells 400 produced by the manufacturer. When the size of the battery cell 400 to be conveyed changes, the positions of the auxiliary blocks 237 can be adjusted adaptively, and the redundant auxiliary blocks 237 can be slid out from the notch 2311 to place the battery cell 400 smoothly.

[0073] Refer to Figure 3 , in some embodiments, flexible abutting members 238 are provided on the opposite side walls of the two clamping blocks 232 and the opposite side walls of the two abutting blocks 234.

[0074] Specifically, the flexible pressing member 238 is a rubber pad or a silica gel pad. Bonding a rubber pad or a silica gel pad on the opposite side walls of the two clamping blocks 232 and the opposite side walls of the two abutting blocks 234 can avoid the possibility of damaging the surface of the battery cell 400 due to the extrusion force when the clamping block 232 or the abutting block 234 contacts the outer surface of the battery cell 400; and through the arrangement of the flexible pressing member 238, it is also convenient for the robotic arm arranged beside the frame 100 to grasp the battery cell 400 subsequently, so that the battery cell 400 can be separated from the carrying tooling 230 smoothly. In addition, the flexible pressing member 238 can also be bonded on the side wall of the auxiliary block 237 to ensure that when the battery cell 400 is clamped, the possibility of damaging the surface of the battery cell 400 due to external force can be reduced.

[0075] In the battery cell anti-drop device of the present application, when the battery cell 400 is being conveyed, if a situation occurs where the robotic arm operates incorrectly and fails to take away the processed battery cell 400 from the conveyor belt 220 in time, then the battery cell 400 will continue to move along with the conveyor belt 220 towards the discharging end of the conveyor belt 220 and gradually approach the sensor 320. When the sensor 320 detects the battery cell 400, it will immediately send a detection signal to the driving motor, so that the driving motor stops working, thereby stopping the conveyor belt 220, and further avoiding the situation where the battery cell 400 drops after reaching the discharging end of the conveyor belt 220, so as to ensure the safety and stability of the conveying process of the battery cell 400; in addition, through the cooperation of the abutting member and the clamping member, stable limiting of the battery cell 400 in the horizontal direction is achieved, and when the abutting block 234 and the clamping block 232 abut against the peripheral side wall of the battery cell 400, it is through the flexible pressing member 238 that abuts against the peripheral side wall of the battery cell 400, which helps to reduce the possibility of damaging the surface of the battery cell 400 and also helps the robotic arm to smoothly grasp the battery cell 400.
