Unless otherwise stated, "a plurality of" means two or more.

[0049] The battery cover operating device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0050] like Figure 1 As shown in the illustration, this application discloses a battery cover operating device for detaching a cap plate 920 with multiple battery covers from multiple battery cylinders. Specifically, the cap plate 920 has multiple battery covers, each corresponding to a battery cylinder body. Therefore, by controlling the cap plate 920 to move away from the battery cylinder bodies, multiple battery covers can be detached from the battery cylinder bodies in one operation, thus improving efficiency. The battery cover operating device includes:

[0051] The rack 100 has a first station 101 for placing a plurality of battery cells. For example, the plurality of battery cells can be placed directly at the first station 101; or, the plurality of battery cells can be placed on a tray 910 and then placed at the first station 101 via the tray 910.

[0052] A pickup device 300 is provided for picking up cap plates 920 disposed on a plurality of battery tubes at a first workstation 101. The pickup device 300 is movable relative to the frame 100 to move closer to or further away from the first workstation 101. For example, the pickup device 300 may be a gripping device, a magnetic suction device, a suspension device, etc., and this application does not limit the specific structure of the pickup device 300.

[0053] The force-applying device 200 applies force to multiple battery cylinders placed at the first station 101 to restrict their upward movement relative to the frame 100 under the action of the pickup device 300. Specifically, due to the large negative pressure between the battery cylinder and the battery cover, when the pickup device 300 moves the cover plate 920 away from the first station 101, it indirectly applies an upward force to the battery cylinder through the battery cover. The force-applying device 200 can resist the upward force indirectly applied to the battery cylinder by the pickup device 300.

[0054] For example, the force-applying device 200 here can be an adsorption device, a clamping device, etc. The adsorption device can be a negative pressure adsorption device or a magnetic adsorption device, which can apply a downward or horizontal force to multiple battery cylinders, thereby fixing the multiple battery cylinders relative to the frame 100. For example, placing the adsorption device below the first station 101 applies a downward force to the battery cylinders, while placing the adsorption device to the side of the first station 101 applies a horizontal force to the battery cylinders. The clamping device here can clamp and fix multiple battery cylinders, fixing the battery cylinders relative to the frame 100. For example, the clamping device can include multiple clamping components, each clamping component clamping each battery cylinder.

[0055] A drive unit 400 is connected to and capable of driving the pickup unit 300 to move so that the cap plate 920 is detached from the multiple battery tubes.

[0056] In this application, the force-applying device 200 can apply force to multiple battery cylinder bodies to restrict the upward movement of the battery cylinder bodies relative to the frame 100 under the action of the picking device 300. The picking device 300 can pick up the cap plate 920. After the force-applying device 200 applies force to the battery cylinder body and the picking device 300 picks up the cap plate 920, the picking device 300 is driven by the driving device 400 to move away from the first station 101, so that the cap plate 920 can be removed from the multiple battery cylinder bodies. As can be seen, in this embodiment, the battery cover is removed from the battery casing by the driving device 400, the force application device 200, and the picking device 300, instead of being removed manually. This can shorten the removal time of the battery cover and improve the removal efficiency. Furthermore, after the force application device 200 applies force to the battery casing, it can prevent the battery casing from being lifted up by the cap plate 920 and thus detached from the first station 101 during the process of the picking device 300 moving away from the first station 101 to remove the cap plate 920, so as to facilitate the subsequent process of the cap plate 920.

[0057] In one alternative embodiment, please refer to Figure 1The frame 100 also has a second station 102 for placing the cap plate 920, and the second station 102 is spaced apart from the first station 101. For example, the first station 101 and the second station 102 can be spaced apart in the vertical direction or in the horizontal direction, and this application does not limit this.

[0058] The drive device 400 can drive the pickup device 300 to move between the first station 101 and the second station 102. In other words, the drive device 400 can drive the cap plate 920 to move between the first station 101 and the second station 102 through the pickup device 300.

[0059] In this embodiment, the driving device 400 can drive the picking device 300 to move between the first station 101 and the second station 102. That is, the driving device 400 can drive the picking device 300 to move in a direction away from the force application device 200, thereby separating the cap plate 920 from the multiple battery packs. Furthermore, the driving device 400 can also drive the disassembled cap plate 920 to move to the second station 102, thereby temporarily storing the cap plate 920 at the second station 102 to facilitate subsequent processes of the cap plate 920, such as cleaning processes. Of course, the frame 100 may only have the first station 101 and no other stations, and this application does not limit this.

[0060] Because the battery compartment is under negative pressure, there is a significant negative pressure between the battery compartment and the battery cover. When this negative pressure exceeds a preset value, the battery compartment cannot be separated from the cover plate 920, which affects subsequent processes of the cover plate 920, such as the cleaning process. Therefore, in an optional embodiment, please refer to... Figure 1 and Figure 4 The battery cover operating device also includes a detection device 500, which is used to detect whether a battery body is connected to the disassembled cover plate 920.

[0061] In this embodiment, the detection device 500 can detect whether a battery body is connected to the disassembled cover plate 920. When the detection device 500 detects that a battery body is connected to the disassembled cover plate 920, the detection device 500 can sound an alarm through the alarm actuator to remind the staff. After receiving the reminder, the staff can manually detach the battery body from the cover plate 920. It should be noted that the alarm actuator here can be a user-configured component or a component built into the battery cover operating device of this application. The above-mentioned alarm function can be achieved by electrically connecting the detection device 500 of this application to the alarm actuator.

[0062] In some embodiments, the detection device 500 is an image acquisition device located to the side of the first station 101 or the second station 102. Since the visible range of the image acquisition device is limited, the image acquisition device can only acquire images of items within a preset height range. That is, the cap plate 920 needs to be within the preset height range to be captured by the image acquisition device. However, the cap plate 920 stays within the preset height range for a short time, which may cause the image acquisition device to fail to capture a clear image of the cap plate 920. This is not conducive to determining whether a battery pack is connected to the cap plate 920.

[0063] In one alternative embodiment, please refer to Figure 4 The detection device 500 is located below the second station 102. The detection device 500 is an image acquisition device with an upward-facing light inlet. For example, the image acquisition device can be a CCD camera, or it can also include an X-ray emitter and a signal detector, i.e., the image acquisition device can also be a security inspection imaging device.

[0064] In this embodiment, the image acquisition device is located below the second station 102, and the light inlet of the image acquisition device faces upward. The cap plate 920 can be detected as long as it is above the second station 102. During the process of the driving device 400 driving the picking device 300, which picks up the cap plate 920, to move to the second station 102, the cap plate 920 will inevitably be above the second station 102, and will inevitably move downward from above the second station 102 to the second station 102. The time required for this process is relatively long, so the image acquisition device can more easily capture a clear image of the cap plate 920, which is helpful in determining whether a battery body is connected to the cap plate 920 and reducing the false judgment rate.

[0065] In other embodiments, the detection device 500 may also be a position sensor, which detects whether the battery body is connected to the cap plate 920.

[0066] Since the battery casing contains electrolyte, the battery cover, located behind the battery casing, may also become contaminated with electrolyte. Electrolyte is corrosive. To prevent electrolyte dripping onto the light inlet of the image acquisition device and thus corroding the lens, in one optional embodiment, please refer to [further details omitted]. Figure 4 The battery cover operating device also includes a light-transmitting sheet 610, which is located above the light inlet.

[0067] In this embodiment, the light-transmitting sheet 610 is located above the light inlet. In this way, even if the electrolyte on the battery cover drips downwards, the electrolyte can only drip onto the light-transmitting sheet 610. That is to say, the light-transmitting sheet 610 can prevent the electrolyte from dripping directly onto the light inlet, thereby preventing the lens of the image acquisition device from being corroded by the electrolyte.

[0068] Because the electrolyte is relatively viscous, electrolyte droplets falling onto the light-transmitting sheet 610 will reduce the quality of the image of the cover plate 920 acquired by the image acquisition device, such as blurry images. In an optional embodiment, the battery cover operating device also includes an airflow control device, which can form a negative pressure airflow or a positive pressure airflow above the light-transmitting sheet 610.

[0069] The airflow control device of this embodiment can form a negative pressure airflow or a positive pressure airflow above the light-transmitting sheet 610. The positive pressure airflow or the negative pressure airflow can be continuous or intermittent. When the positive pressure airflow or the negative pressure airflow is continuous, the positive pressure airflow and the negative pressure airflow can apply a lateral force to the dripping electrolyte (i.e., the electrolyte that has not yet dripped onto the light-transmitting sheet 610), thereby causing the dripping trajectory of the electrolyte to deviate from the light-transmitting sheet 610, so as to prevent the electrolyte from falling onto the light-transmitting sheet 610, thereby ensuring the quality of the image of the cover plate 920 acquired by the image acquisition device.

[0070] When the positive or negative airflow is intermittent, the positive or negative airflow can exert a lateral force on the electrolyte dripping onto the light-transmitting sheet 610, thereby causing the electrolyte to detach from the light-transmitting sheet 610, thus ensuring the quality of the image acquired by the image acquisition device.

[0071] In an alternative embodiment, the force-applying device 200 is capable of applying a downward force to a plurality of battery cylinders placed at the first station 101.

[0072] Because there is a large negative pressure between the battery body and the battery cover, when the pickup device 300 moves the cap plate 920 away from the first station 101, the pickup device 300 will indirectly exert an upward force on the battery body through the battery cover. Therefore, the downward force applied by the force application device 200 to the battery body can better balance the upward force indirectly applied by the pickup device 300 to the battery body, so as to better limit the upward movement of the battery body relative to the frame 100 under the action of the pickup device 300.

[0073] The operation of removing the battery cover is as follows: the pick-up device 300 picks up the cover plate 920 and the force application device 200 applies a downward force to the multiple battery tubes. Then, the drive device 400 drives the pick-up device 300 to move away from the first station 101, so that the pick-up device 300 and the force application device 200 are relatively far apart, thereby removing the cover plate 920 from the battery tube.

[0074] In one alternative embodiment, please refer to Figure 2 and Figure 3 The force-applying device 200 includes a magnetic component located below the first station 101. For example, the magnetic component may include multiple spaced electromagnetic coils 210, each corresponding to a battery cell body. By passing current through the electromagnetic coils 210, an attractive force is generated. This embodiment uses a magnetic component to apply attractive or repulsive forces to multiple battery cells, resulting in a simple structure, convenient control, and a highly sensitive magnetic component response.

[0075] In one alternative embodiment, please refer to Figure 2 and Figure 3 The battery cover operating device also includes a mounting plate 640 and a second driving member 710. A magnetic component is disposed on the mounting plate 640, and a first positioning member 720 is provided on the mounting plate 640. The second driving member 710 is connected to the mounting plate 640 and can drive the mounting plate 640 to move up and down between a first position and a second position. For example, the mounting plate 640 has a plurality of mounting holes, and each battery coil is disposed in each mounting hole; furthermore, the mounting plate 640 may also have a plurality of through holes 641, which are spaced apart from the mounting holes, thereby reducing the weight of the mounting plate 640.

[0076] When the mounting plate 640 is in the first position, the first positioning member 720 is located below the first station 101; when the mounting plate 640 is in the second position, the first positioning member 720 is located inside the first station 101 to be positioned and cooperate with the tray 910 that carries multiple battery cylinders.

[0077] The specific operation process is as follows: After placing the tray 910 carrying multiple battery cells in the first station 101, the second driving component 710 can be used to drive the mounting plate 640 to move upward from the first position. This allows the first positioning component 720 on the mounting plate 640 to gradually enter the first station 101 to cooperate with the tray 910 in positioning, thereby correcting the position of the tray 910 and making the tray 910 accurately located in the first station 101, so that the picking device 300 can pick up the cap plate 920; and it also facilitates the force application device 200 to fix each battery cell on the frame 100.

[0078] In an alternative embodiment, the mounting plate 640 has a bearing surface for supporting the tray 910, and the second drive member 710 is also capable of driving the mounting plate 640 to a third position, which is located between the first position and the third position. When the mounting plate 640 is in the third position, the bearing surface is located within or above the first station 101 to apply an upward force to the tray 910.

[0079] In addition to disassembling the cover plate 920, the battery cover operating device of this application can also close the cover plate 920. That is, the battery cover operating device can also close the cover plate 920 onto multiple battery cells. The operation of closing the battery cover is as follows: the pick-up device 300 picks up the cover plate 920, and the drive device 400 drives the pick-up device 300 to move towards the first station 101 so that the cover plate 920 is located above the multiple battery cells. The drive device 400 continues to move the pick-up device 300 in a direction close to the first station 101, so that the pick-up device 300 applies a downward force to the cover plate 920, thereby connecting the battery cover to the battery cell.

[0080] In this embodiment, the second driving member 710 can also drive the mounting plate 640 to move to the third position. When the mounting plate 640 is in the third position, the bearing surface is located within or above the first station 101, thereby applying an upward force to the tray 910 located in the first station 101. Therefore, during the process of closing the cap plate 920, when the picking device 300 applies a downward force to the cap plate 920, the second driving member 710 can also drive the mounting plate 640 to move to the third position, applying an upward force to the battery body. Under the combined action of the upward and downward forces, the connection between the battery cap and the battery body can be made tighter, preventing the electrolyte inside the battery body from evaporating.

[0081] In one alternative embodiment, please refer to Figure 5 and Figure 6 The pickup device 300 includes a first driving member 310 and a pickup rod 320. The pickup rod 320 has a hook-on portion 321 protruding from its outer peripheral surface. The first driving member 310 is connected to the pickup rod 320 and can drive the pickup rod 320 to move horizontally. Here, the first driving member 310 can be a cylinder, electric cylinder, or other device. The driving device 400 is connected to the pickup device 300 and can drive the pickup device 300 to move vertically. It should be noted that this embodiment is adapted to a cap plate 920 with a limiting hole 922. Please refer to [link to relevant documentation]. Figure 8 and Figure 9 The limiting hole 922 is gourd-shaped and may include a clearance section 923 and a limiting section 924. The cross-sectional area of ​​the clearance section 923 is larger than that of the limiting section 924.

[0082] The process of removing the cap plate 920 from the multiple battery packs in this embodiment is as follows: The drive device 400 drives the pickup device 300 to move downward, so that the hook part 321 of the pickup rod 320 passes through the clearance section 923. Then, the first drive member 310 drives the pickup rod 320 to move horizontally, so that the hook part 321 is opposite to the limiting section 924. Then, the drive device 400 can drive the pickup device 300 to move upward. During this process, the hook part 321 will make limiting contact with the lower hole edge of the limiting section 924, thereby lifting the cap plate 920 upward and separating it from the multiple battery packs.

[0083] In this embodiment, the working process of placing the cap plate 920 on multiple battery cells is as follows: The cap plate 920 is suspended by the hook part 321, so that the cap plate 920 is above the first work station 101. The driving device 400 drives the picking device 300 to move downward. When the battery cover on the cap plate 920 contacts the battery cell, the picking device 300 is further driven to move downward. During this process, the picking rod 320 will disengage from the cap plate 920 and extend further below the cap plate 920, but the part of the picking device 300 above the cap plate 920 will contact the cap plate 920, thereby pressing the cap plate 920 downward and connecting the battery cover on the cap plate 920 to the battery cell.

[0084] To detect whether the pickup rod 320 contacts the cap plate 920 during the pickup process, in an optional embodiment, please refer to... Figure 6 The pickup device 300 also includes a sliding seat 330, a driving device 400 connected to the sliding seat 330 or a first driving member 310, the first driving member 310 connected to the sliding seat 330, a pickup rod 320 slidingly engaging with the sliding seat 330 in the vertical direction, a hook-on part 321 located below the sliding seat 330, and a position sensor 620 connected to the sliding seat 330 or the first driving member 310, the position sensor 620 located above the sliding seat 330, and the position sensor 620 used to detect whether the pickup rod 320 moves upward relative to the position sensor 620.

[0085] The specific detection process in this embodiment is as follows: During the process of the driving device 400 driving the sliding seat 330 or the first driving member 310 to move downward, the pickup rod 320 and the position sensor 620 will also move downward. If the pickup rod 320 of the pickup device 300 is misaligned with the limiting hole 922 and is opposite to the solid part of the cap plate 920, the pickup rod 320 of the pickup device 300 will contact the solid part of the cap plate 920. After the pickup rod 320 contacts the solid part of the cap plate 920, if the driving device 400 further drives the sliding seat 330 or the first driving member 310 to move downward, the position sensor 620 will further follow and continue to move downward, while the pickup rod 320 will not follow and continue to move downward. Therefore, the pickup rod 320 will slide upward relative to the sliding seat 330 and the position sensor 620, and thus be detected by the position sensor 620. As can be seen, this embodiment can determine whether the pickup rod 320 has accidentally touched the cap plate 920 by detecting whether the pickup rod 320 moves upward relative to the position sensor 620. In this way, the alarm actuator can be used to remind the staff to resolve the fault, thereby improving the accuracy of picking up the cap plate 920.

[0086] In a further embodiment, the pickup rod 320 is provided with a stop portion 322 protruding from its outer peripheral surface. The stop portion 322 is located above the hook portion 321. The stop portion 322 is in upper limit contact with the sliding seat 330 in the vertically downward direction. That is to say, the pickup rod 320 is hooked onto the sliding seat 330 through the stop portion 322.

[0087] In one alternative embodiment, please refer to Figure 7 The frame 100 also has a second station 102 for placing the cap plate 920. The second station 102 is horizontally spaced from the first station 101. The driving device 400 can also drive the picking device 300 along the arrangement direction of the first station 101 and the second station 102. Figure 7 Move in the direction indicated by the y-arrow line.

[0088] Furthermore, the drive unit 400 can also drive the pickup unit 300 along the first direction ( Figure 7 The pickup device 300 moves in the direction indicated by the arrow in the middle. The first direction is perpendicular to the above-mentioned arrangement direction and the vertical direction, respectively, so as to adjust the position of the pickup device 300 in the first direction, thereby ensuring that the pickup device 300 can pick up the cap plate 920.

[0089] For example, the driving device 400 includes a first driving mechanism and a second driving mechanism. The first driving mechanism is connected to the first driving member 310 and can drive the first driving member 310 in the vertical direction. Figure 7The movement is in the direction indicated by the arrow in the middle (z). For example, the first drive mechanism can be a cylinder, an electric cylinder, etc.

[0090] The first drive mechanism and the frame 100 are arranged in the first station 101 and the second station 102. Figure 7 The second drive mechanism slides along the direction indicated by the y-arrow line in the diagram, and is connected to the first drive mechanism, enabling the first drive mechanism to move along the aforementioned arrangement direction. For example, the second drive mechanism may include a motor and sprocket chain mechanism, or a motor and lead screw and nut mechanism, or it may be a traveling mechanism, etc.

[0091] Furthermore, the drive unit 400 also includes a connecting beam and a third drive mechanism. The third drive mechanism may include a motor and a lead screw and nut mechanism, or a motor and a sprocket and chain mechanism. The first drive mechanism and the connecting beam are in a first direction ( Figure 7 The connecting beam and the frame 100 slide in the direction indicated by the arrow in the middle. The second drive mechanism is connected to the first drive mechanism through the connecting beam. The second drive mechanism can drive the connecting beam to move in the direction indicated by the arrow. The third drive mechanism is located on the connecting beam and connected to the first drive mechanism to drive the first drive mechanism to move in the first direction.

[0092] In one alternative embodiment, please refer to Figure 10 The first station 101 is used to place a tray 910 that carries multiple battery tubes. The tray 910 is provided with a snap-fit ​​seat 911, and the snap-fit ​​seat 911 is provided with a snap-fit ​​part 912. The snap-fit ​​seat 911 and the tray 910 slide in the vertical direction. The cap plate 920 is provided with a snap-fit ​​mating part 921, and the snap-fit ​​part 912 snaps into the snap-fit ​​mating part 921. For example, one of the snap-fit ​​part 912 and the snap-fit ​​mating part 921 can be a spring ball, and the other can be a slot. The snap-fit ​​seat 911 can be provided on the tray 910 by an elastic element, and the snap-fit ​​seat 911 can be reset by the elastic element after being pressed down by the telescopic member 630.

[0093] The snap-fit ​​between the cap plate 920 and the tray 910 allows the cap plate 920 to be more stably connected to multiple battery cells, and also allows the battery cells to be stably placed on the tray 910, preventing the battery cells from shaking and falling off the tray 910 during transportation.

[0094] The battery cover operating device also includes a telescopic member 630, which is connected to the pickup device 300. The telescopic member 630 can extend to allow the locking seat 911 to slide downward, thereby disengaging the locking part 912 from the locking engagement part 921. In other words, after the pickup device 300 picks up the cover plate 920, the telescopic member 630 and the locking seat 911 are arranged opposite each other in the vertical direction.

[0095] The specific working process of this embodiment is as follows: After the picking device 300 picks up the cap plate 920 and before the driving device 400 lifts the cap plate 920 upward, the cap plate 920 and the tray 910 are locked by the locking part 912 and the locking engagement part 921. If the cap plate 920 is lifted upward at this time, the tray 910 and the battery body located therein will also move upward, which will cause the cap plate 920 to be unable to separate from the battery body. Therefore, it is necessary to use the telescopic member 630 of this embodiment to disengage the locking part 912 and the locking engagement part 921 from the locking state. That is, control the telescopic member 630 to extend to press the locking seat 911, so that the locking seat 911 slides downward. At this time, the locking part 912 on the locking seat 911 will disengage from the locking engagement part 921 on the cap plate 920. In this way, lifting the cap plate 920 upward can separate the cap plate 920 from the battery body.

[0096] In some embodiments, please refer to Figure 5 and Figure 6 The battery cover operating device also includes a base plate 650, a telescopic member 630, and a pickup device 300, all disposed on the base plate 650. The hook portion 321 of the pickup rod 320 is located below the base plate 650. The first driving member 310 can be disposed on the upper surface of the base plate 650. The driving device 400 is connected to the base plate 650 and can drive the base plate 650 to move vertically. It should be noted that when the battery cover is closed using the battery cover operating device, the portion of the pickup device 300 above the cap plate 920 can press the cap plate 920 through the base plate 650, thereby connecting the cap plate 920 to the battery body.

[0097] In a further embodiment, the battery cover operating device also includes a collision sensor 660, which is connected to the substrate 650 and located on the periphery of the substrate 650. The collision sensor 660 can detect whether the substrate 650 collides with other devices and adjust the movement direction of the battery cover operating device in a timely manner.

[0098] In one alternative embodiment, please refer to Figure 1 and Figure 2 The frame 100 includes a frame body 110 and a first conveying device 120. For example, the first conveying device 120 can be a belt conveyor, roller conveyor, chain conveyor, etc. The first conveying device 120 is connected to the frame body 110, and the conveying direction of the first conveying device 120 is (…). Figure 2The direction indicated by the arrow m in the middle extends horizontally. The first station 101 is located above the first conveying device 120. The first conveying device 120 is used to carry the tray 910 containing multiple battery boxes and can convey the tray 910 towards the first station 101. Specifically, in this embodiment, the first conveying device 120 can be connected to an external conveyor line. That is, the tray 910 conveyed by the external conveyor line can be conveyed to the first conveying device 120 and then conveyed to the first station 101 by the first conveying device 120.

[0099] Please see Figure 2 and Figure 3 The battery cover operating device also includes a first positioning device 700, which includes the second driving member 710 and the first positioning member 720 described above. The second driving member 710 is connected to the first positioning member 720, which is located outside the first station 101. The second driving member 710 can drive the first positioning member 720 to move towards the first station 101, so that the first positioning member 720 is positioned and engaged with the tray 910 provided on the first conveying device 120, and the tray 910 is positioned at the first station 101. Exemplarily, the first positioning member 720 and the second driving member 710 may be located below, to the side or above the first station 101, and this application does not limit this.

[0100] In this embodiment, the first positioning member 720 is located outside the first station 101. This prevents the pallet 910 from interfering with the first positioning member 720 during the conveying process of the first conveying device 120. After the first conveying device 120 conveys the pallet 910 to a position close to the first station 101, the second driving member 710 can drive the first positioning member 720 to move towards the first station 101, so that the first positioning member 720 and the pallet 910 are positioned and engaged, thereby correcting the position of the pallet 910 so that it is accurately located at the first station 101, so that the picking device 300 can pick up the cap plate 920; and it is also beneficial for the force application device 200 to fix each battery body on the frame 100.

[0101] In some embodiments, the first positioning member 720 includes a first push block 721 and a positioning pin 722. The first push block 721 is located on one side of the first station 101 along the conveying direction of the first conveying device 120. The first push block 721 has a first guide surface. The first guide surface is inclined toward the edge of the first station 101 along the conveying direction of the first conveying device 120. The first guide surface is located between the positioning pin 722 and the first station 101.

[0102] When the travel of the first conveying device 120 is too large, causing the pallet 910 to exceed the first station 101, the first pusher 721 will contact the part of the pallet 910 that exceeds the first station 101 during the process of moving towards the first station 101. This will cause the pallet 910 to move in the opposite direction of the conveying direction of the first conveying device 120, so that the pallet 910 is positioned in the conveying direction of the first conveying device 120. When the second drive member 710 continues to drive the first positioning member 720 closer to the first station 101, the positioning pin 722 will engage with the pallet 910 to position it, so that the pallet 910 is accurately positioned at the first station 101.

[0103] Furthermore, the first positioning member 720 also includes a second push block, the first station 101 is located on one side of the second push block along the conveying direction of the first conveying device 120, the second push block has a second guide surface, the second guide surface is inclined toward the first edge of the first station 101 in the opposite direction of the conveying direction of the first conveying device 120.

[0104] When the travel of the first conveying device 120 is too small, causing the pallet 910 to not fully enter the first station 101, the first guide surface will contact the part of the pallet 910 that has not yet entered the first station 101, thereby causing the pallet 910 to move along the conveying direction of the first conveying device 120, so that the pallet 910 is positioned in the conveying direction of the first conveying device 120.

[0105] In some embodiments, a stop block 140 is provided on the frame 100. The stop block 140 is located on one side of the first station 101 along the conveying direction of the first conveying device 120. The stop block 140 can stop and limit the pallet 910 to prevent the pallet 910 from falling off the first conveying device 120.

[0106] In one alternative embodiment, please refer to Figure 4 The frame 100 also includes a second conveying device 130, which is horizontally spaced from the first conveying device 120. The second conveying device 130 is connected to the frame 110, and the conveying direction of the second conveying device 130 is ( Figure 4 The direction indicated by the arrow (k) extends horizontally. The second station 102 is located above the second conveying device 130, which carries the pallet 910 containing the cap plate 920 and can convey the pallet 910 towards the second station 102. For example, the conveying direction of the second conveying device 130 can be perpendicular to the conveying direction of the first conveying device 120, thereby shortening the length of the production line and facilitating factory layout; of course, the conveying direction of the second conveying device 130 can also be parallel to the conveying direction of the first conveying device 120, and this application does not limit this.

[0107] Please continue reading.Figure 4 The battery cover operating device also includes a second positioning device 800, which includes a third driving member 810 and a second positioning member 820. The third driving member 810 is connected to the second positioning member 820, which is located outside the second station 102. The third driving member 810 can drive the second positioning member 820 to move towards the second station 102, so that the second positioning member 820 is positioned and engaged with the tray 910 provided on the second conveying device 130, and the tray 910 is positioned at the second station 102, thereby enabling the picking device 300 to accurately pick up the cover plate 920. It should be noted that the structure of the second positioning member 820 can be the same as that of the first positioning member 720, and this application will not elaborate on this further.

[0112] The cap plate 920 of this application is provided with multiple battery covers, and the multiple battery covers on the cap plate 920 are connected to multiple battery bodies one by one. Therefore, by controlling the cap plate 920 to move away from the battery bodies, multiple battery covers can be removed from multiple battery bodies at once, thus achieving the purpose of improving efficiency.

[0113] In an optional embodiment, the cap removal step further includes:

[0117] S620 After removing the battery body, transfer the cap plate 920 to the cleaning station to prevent the battery body from being taken to the cleaning station.

[0118] In an optional embodiment, the battery cover operation method further includes a cover-fastening step, which includes:
