[0060] The battery cover operating device and the battery cover operating method provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0061] like Figure 1As shown, the embodiment of the present application discloses a battery cover manipulation device, which is used to remove a cap plate 920 provided with multiple battery covers from multiple battery barrels, that is, the cap plate 920 is provided with multiple battery covers, and the multiple battery covers on the cap plate 920 are connected to the multiple battery barrels in a one-to-one correspondence. Therefore, by controlling the cap plate 920 to be relatively away from the battery barrels, the multiple battery covers can be removed from the multiple battery barrels at one time, so that the purpose of improving efficiency can be achieved. The battery cover manipulation device includes:

[0062] The rack 100 has a first station 101 for placing a plurality of battery cylinders. Exemplarily, the plurality of battery cylinders can be directly placed in the first station 101; or, the plurality of battery cylinders can be placed on a tray 910 and then placed in the first station 101 through the tray 910.

[0063] The picking device 300 is used to pick up the cap plates 920 on the multiple battery barrels arranged at the first station 101. The picking device 300 can move relative to the frame 100 to approach or move away from the first station 101. Exemplarily, the picking device 300 can be a grasping device, a magnetic device, a suspension device, etc., and the present application does not limit the specific structure of the picking device 300.

[0064] The force-applying device 200 can apply force to the multiple battery barrels placed in the first station 101 to limit the upward movement of the battery barrels relative to the frame 100 under the action of the picking device 300. Specifically, since there is a large negative pressure between the battery barrel and the battery cover, when the picking device 300 drives the cap plate 920 away from the first station 101, the picking device 300 will indirectly apply an upward force to the battery barrel through the battery cover, and the force-applying device 200 here can resist the upward force indirectly applied by the picking device 300 to the battery barrel.

[0065] Exemplarily, 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, and the adsorption device can be used to apply a downward or horizontal force to multiple battery barrels, so that the multiple battery barrels are fixed relative to the rack 100. For example, if the adsorption device is set below the first station 101, a downward force is applied to the battery barrel, and if the adsorption device is set to the side of the first station 101, a horizontal force is applied to the battery barrel. The clamping device here can clamp and fix multiple battery barrels, so that the battery barrels are fixed relative to the rack 100. For example, the clamping device can include multiple clamping components, and each clamping component clamps each battery barrel respectively.

[0066] The driving device 400 is connected to the picking device 300 and can drive the picking device 300 to move so that the cap plate 920 can be removed from the plurality of battery barrels.

[0067] In the present application, the force-applying device 200 can apply a force to the multiple battery barrels to limit the upward movement of the battery barrels 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 a force to the battery barrel and the picking device 300 picks up the cap plate 920, the picking device 300 is driven by the driving device 400 to move in a direction away from the first workstation 101, so that the cap plate 920 can be removed from the multiple battery barrels. It can be seen that in this embodiment, the battery cover is removed from the battery body by the driving device 400, the force-applying device 200 and the picking device 300, rather than by manual removal, which can shorten the removal time of the battery cover and improve the removal efficiency; and, after the force-applying device 200 applies force to the battery body, it can prevent the picking device 300 from being lifted up by the cap plate 920 and thus separated from the first station 101 during the process of 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.

[0068] In an alternative embodiment, see Figure 1 The 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 the present application is not limited thereto.

[0069] 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 cap plate 920 to move between the first station 101 and the second station 102 through the picking device 300 .

[0070] 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-applying device 200, so that the cap plate 920 is separated from the plurality of battery barrels; and the driving device 400 can also drive the disassembled cap plate 920 to move to the second station 102, so that the cap plate 920 is temporarily stored in the second station 102, so as to facilitate the subsequent process of the cap plate 920, such as the cleaning process. Of course, the rack 100 may also only have the first station 101 without other stations, and this application is not limited to this.

[0071] Since the battery body is in a negative pressure environment, there is a large negative pressure between the battery body and the battery cover. When the negative pressure between the battery body and the battery cover exceeds a preset value, the battery body cannot be separated from the cap plate 920, which will affect the subsequent processes of the cap 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 further includes a detection device 500, which is used to detect whether the battery barrel is connected to the disassembled cap plate 920.

[0072] In this embodiment, the detection device 500 can detect whether the battery barrel is connected to the disassembled cap plate 920. When the detection device 500 detects that the battery barrel is connected to the disassembled cap plate 920, the detection device 500 can alarm through the alarm actuator to remind the staff, and the staff can manually separate the battery barrel from the cap plate 920 after receiving the reminder. It should be noted that the alarm actuator here can be a component configured by the user, or it can also be a component of the battery cover operating device of the present application. The above-mentioned alarm function can be realized by electrically connecting the detection device 500 of the present application with the alarm actuator.

[0073] In some embodiments, the detection device 500 is an image acquisition device, which is located on the side of the first workstation 101 or the second workstation 102. Since the visual range of the image acquisition device is limited, the image acquisition device can only acquire images of objects within a preset height range. In other words, the cap plate 920 needs to be within the preset height range to be captured by the image acquisition device, and the cap plate 920 stays within the preset height range for a short time, which may cause the image acquisition device to be unable to capture a clear image of the cap plate 920, which is not conducive to determining whether the battery barrel is connected to the cap plate 920.

[0074] In an alternative embodiment, see Figure 4 The detection device 500 is disposed below the second workstation 102. The detection device 500 is an image acquisition device having an upwardly disposed light inlet. Exemplarily, the image acquisition device may be a CCD camera, or the image acquisition device may also include an X-ray emitter and a signal detector, that is, the image acquisition device may also be a security inspection imaging device.

[0075] In this embodiment, the image acquisition device is located below the second station 102, and the light entrance of the image acquisition device faces upward, so the cap plate 920 can be detected as long as it is located above the second station 102. In the process of the driving device 400 driving the picking device 300 with the cap plate 920 to move to the second station 102, the cap plate 920 will inevitably be located above the second station 102, and will inevitably move downward from the second station 102 to the second station 102, and the time required for this process is relatively long, so the image acquisition device can easily capture a clear image of the cap plate 920, so as to facilitate the judgment of whether the battery barrel is connected to the cap plate 920, thereby reducing the misjudgment rate.

[0076] 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 through the position sensor.

[0077] Since the battery body contains electrolyte, the battery cover disposed behind the battery body may also be stained with electrolyte, and the electrolyte is corrosive. In order to prevent the electrolyte from dripping onto the light inlet of the image acquisition device and corroding the lens of the image acquisition device, in an optional embodiment, please continue to refer to Figure 4 The battery cover operating device further includes a light-transmitting sheet 610, which is disposed above the light entrance.

[0078] In this embodiment, the light-transmitting sheet 610 is disposed above the light entrance, so that even if the electrolyte on the battery cover drips downward, the electrolyte can only drip onto the light-transmitting sheet 610. In other words, the light-transmitting sheet 610 can prevent the electrolyte from dripping directly into the light entrance, thereby preventing the lens of the image acquisition device from being corroded by the electrolyte.

[0079] Since the electrolyte is relatively viscous, electrolyte dripping onto the light-transmitting sheet 610 will reduce the quality of the image of the cap plate 920 acquired by the image acquisition device, such as blurred image. In an optional embodiment, the battery cover manipulation 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.

[0080] 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 here 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 exert a lateral force on the dripping electrolyte (i.e., the electrolyte that has not yet dripped onto the light-transmitting sheet 610), so that the dripping trajectory of the electrolyte deviates from the light-transmitting sheet 610, so as to prevent the electrolyte from falling on the light-transmitting sheet 610, thereby ensuring the quality of the image of the cap plate 920 acquired by the image acquisition device.

[0081] When the positive pressure airflow or the negative pressure airflow is intermittent, the positive pressure airflow or the negative pressure airflow can exert a lateral force on the electrolyte dripping on the light-transmitting sheet 610, so that the electrolyte is separated from the light-transmitting sheet 610, thereby ensuring the quality of the image captured by the image acquisition device.

[0082] In an optional embodiment, the force applying device 200 can apply a downward force to the multiple battery cylinders placed in the first station 101 .

[0083] Since there is a large negative pressure between the battery body and the battery cover, when the picking device 300 drives the cap plate 920 away from the first workstation 101, the picking device 300 will indirectly apply an upward force to the battery body through the battery cover. Therefore, the downward force applied by the force-applying device 200 to the battery body can better balance the upward force indirectly applied by the picking 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 picking device 300.

[0084] The operation of removing the battery cover is as follows: use the picking device 300 to pick up the cap plate 920 and use the force-applying device 200 to apply a downward force to multiple battery barrels, and then use the driving device 400 to drive the picking device 300 to move in a direction away from the first workstation 101, so that the picking device 300 and the force-applying device 200 are relatively far away from each other, thereby removing the cap plate 920 from the battery barrel.

[0085] In an alternative embodiment, see Figure 2 and Figure 3 The force applying device 200 includes a magnetic component, which is arranged below the first station 101. For example, the magnetic component here may include a plurality of electromagnetic coils 210 distributed at intervals, each electromagnetic coil 210 corresponds to each battery barrel, and an attraction force is generated by passing current through the electromagnetic coil 210. In this embodiment, the magnetic component is used to apply an attraction force or a repulsion force to a plurality of battery barrels, and the structure is simple and the control is convenient, and the magnetic component is more sensitive.

[0086] In an alternative embodiment, see Figure 2 and Figure 3 The battery cover manipulation device further includes a mounting plate 640 and a second driving member 710. The magnetic assembly is disposed on the mounting plate 640. The mounting plate 640 is provided with a first positioning member 720. The second driving member 710 is connected to the mounting plate 640 and can drive the mounting plate 640 to rise and fall between the first position and the second position. Exemplarily, the mounting plate 640 is provided with a plurality of mounting holes, and each battery coil is respectively disposed in each mounting hole; further, the mounting plate 640 may also be provided with a plurality of through holes 641, and the through holes 641 are spaced apart from the mounting holes, which can reduce the weight of the mounting plate 640.

[0087] When the mounting plate 640 is located at the first position, the first positioning member 720 is located below the first station 101; when the mounting plate 640 is located at the second position, the first positioning member 720 is located within the first station 101 to be positioned and matched with the tray 910 carrying multiple battery cylinders.

[0088] The specific operation process is as follows: after placing the tray 910 carrying multiple battery cylinders on the first station 101, the second driving member 710 can be used to drive the mounting plate 640 to move upward from the first position, which allows the first positioning member 720 provided 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 at the first station 101, so as to facilitate the picking device 300 to pick up the cap plate 920; and facilitate the force-applying device 200 to fix each battery cylinder on the frame 100.

[0089] In an optional embodiment, the mounting plate 640 has a bearing surface for supporting the tray 910, and the second driving member 710 can also drive the mounting plate 640 to move to a third position, the second position is located between the first position and the third position, and when the mounting plate 640 is located at the third position, the bearing surface is located in the first workstation 101 or above the first workstation 101 to apply an upward force to the tray 910.

[0090] In addition to removing the cap plate 920, the battery cover manipulation device of the present application can also cover the cap plate 920, that is, the battery cover manipulation device can also cover the cap plate 920 on multiple battery barrels. The operation of covering the battery cover is as follows: the cap plate 920 is picked up by the picking device 300, and the driving device 400 drives the picking device 300 to move toward the first station 101 so that the cap plate 920 is located above the multiple battery barrels. The driving device 400 continues to move the picking device 300 in a direction close to the first station 101, so that the picking device 300 applies a downward force to the cap plate 920, thereby connecting the battery cover to the battery barrel.

[0091] The second driving member 710 of this embodiment can also drive the mounting plate 640 to move to the third position. When the mounting plate 640 is located at the third position, the bearing surface is located in the first station 101 or above the first station 101, thereby applying an upward force to the tray 910 located in the first station 101. Therefore, in the process of covering 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 be used to drive the mounting plate 640 to move to the third position, and apply an upward force to the battery barrel. Under the combined action of the upward and downward forces, the connection between the battery cover and the battery barrel can be made tighter to prevent the electrolyte in the battery barrel from volatilizing.

[0092] In an alternative embodiment, see Figure 5 and Figure 6 The pickup device 300 includes a first driving member 310 and a pickup rod 320. The pickup rod 320 is provided with a hanging portion 321 protruding from its outer circumference. The first driving member 310 is connected to the pickup rod 320 and can drive the pickup rod 320 to move in the horizontal direction. The first driving member 310 here can be a cylinder, an electric cylinder, etc. The driving device 400 is connected to the pickup device 300 and can drive the pickup device 300 to move in the vertical direction. It should be noted that this embodiment is adapted to a cap plate 920 with a limiting hole 922, please refer to Figure 8 and Fig. 9 The limiting hole 922 is in the shape of a gourd mouth, and the limiting hole 922 may include an avoidance section 923 and a limiting section 924 , and the cross-sectional area of ​​the avoidance section 923 is greater than the cross-sectional area of ​​the limiting section 924 .

[0093] The working process of removing the cap plate 920 from multiple battery barrels in this embodiment is as follows: the pick-up device 300 is driven to move downward by the driving device 400, so that the hanging portion 321 of the pick-up rod 320 passes through the avoidance section 923, and then the pick-up rod 320 is driven to move horizontally by the first driving member 310, so that the hanging portion 321 is opposite to the limiting section 924, and then the pick-up device 300 can be driven to move upward by the driving device 400. During this process, the hanging portion 321 will be in 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 barrels.

[0094] The working process of setting the cap plate 920 on multiple battery barrels in this embodiment is as follows: the cap plate 920 is hung by the hanging part 321, so that the cap plate 920 is located above the first workstation 101, and the driving device 400 drives the picking device 300 to move downward. When the battery cover on the cap plate 920 contacts the battery barrel, the picking device 300 is further driven to move downward. During this process, the picking rod 320 will be out of contact with the cap plate 920 and extend further to the bottom of the cap plate 920, but the part of the picking device 300 located above the cap plate 920 will contact the cap plate 920, thereby pressing the cap plate 920 downward, so that the battery cover on the cap plate 920 is connected to the battery barrel.

[0095] In order to detect whether the pick-up rod 320 touches the cap plate 920 during the process of the pick-up device 300 picking up the cap plate 920, in an optional embodiment, refer to Figure 6 The picking device 300 also includes a sliding seat 330, the driving device 400 is connected to the sliding seat 330 or the first driving member 310, the first driving member 310 is connected to the sliding seat 330, the picking rod 320 and the sliding seat 330 slide in cooperation in the vertical direction, the hanging portion 321 is located below the sliding seat 330, the picking device 300 also includes a position sensor 620, the position sensor 620 is connected to the sliding seat 330 or the first driving member 310, the position sensor 620 is located above the sliding seat 330, and the position sensor 620 is used to detect whether the picking rod 320 moves upward relative to the position sensor 620.

[0096] The specific detection process of this embodiment is as follows. In the process that the driving device 400 drives the sliding seat 330 or the first driving member 310 to move downward, the picking rod 320 and the position sensor 620 will also move downward. If the picking rod 320 of the picking device 300 is misaligned with the limiting hole 922 and is opposite to the solid part of the cap plate 920, the picking rod 320 of the picking device 300 will contact the solid part of the cap plate 920. After the picking 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 picking rod 320 will not follow and continue to move downward. Therefore, the picking rod 320 will slide upward relative to the sliding seat 330 and the position sensor 620, thereby being detected by the position sensor 620. It can be seen that this embodiment can determine whether the picking rod 320 accidentally touches the cap plate 920 by detecting whether the picking rod 320 moves upward relative to the position sensor 620. In this way, the alarm actuator can be used to remind the staff to solve the fault, thereby improving the accuracy of picking up the cap plate 920.

[0097] In a further embodiment, the picking rod 320 is provided with a stop portion 322 protruding from its outer circumferential surface, and the stop portion 322 is located above the hanging portion 321. The stop portion 322 contacts the upper limit position in the vertical downward direction of the sliding seat 330. That is, the picking rod 320 is hung on the sliding seat 330 through the stop portion 322.

[0098] In an alternative embodiment, please see Figure 7 The frame 100 also has a second station 102 for placing the cap plate 920, and the second station 102 is arranged horizontally with the first station 101, and the driving device 400 can also drive the picking device 300 to move 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 in the figure.

[0099] Furthermore, the driving device 400 can also drive the picking device 300 to move along the first direction ( Figure 7 The first direction is perpendicular to the arrangement direction and the vertical direction, respectively, to adjust the position of the picking device 300 in the first direction, thereby ensuring that the picking device 300 can pick up the cap plate 920.

[0100] Exemplarily, the driving device 400 includes a first driving mechanism and a second driving mechanism, wherein the first driving mechanism is connected to the first driving member 310 and can drive the first driving member 310 to move in a vertical direction ( Figure 7 The first driving mechanism moves in the direction indicated by the arrow line z in the figure. Exemplarily, the first driving mechanism can be a pneumatic cylinder, an electric cylinder, etc.

[0101] The first driving mechanism and the frame 100 are arranged in the first station 101 and the second station 102 ( Figure 7 The second drive mechanism is connected to the first drive mechanism and can drive the first drive mechanism to move along the arrangement direction. Exemplarily, the second drive mechanism may include a motor and a sprocket chain mechanism, or a motor and a screw nut mechanism, or may also be a traveling mechanism.

[0102] Furthermore, the driving device 400 further includes a connecting beam and a third driving mechanism, the third driving mechanism may include a motor and a screw nut mechanism, or a motor and a sprocket chain mechanism, the first driving mechanism and the connecting beam are in the first direction ( Figure 7 The connecting beam and the frame 100 slide in the above arrangement direction, and the second driving mechanism is connected to the first driving mechanism through the connecting beam, and the second driving mechanism can drive the connecting beam to move along the above arrangement direction; the third driving mechanism is arranged on the connecting beam and connected to the first driving mechanism to drive the first driving mechanism to move in the first direction.

[0103] In an alternative embodiment, see Fig.10 The first station 101 is used to place a tray 910 carrying multiple battery cylinders. The tray 910 is provided with a snap-in seat 911, and the snap-in seat 911 is provided with a snap-in portion 912. The snap-in seat 911 and the tray 910 are slidably matched in the vertical direction. The cap plate 920 is provided with a snap-in fitting portion 921, and the snap-in fitting portion 912 is snap-fitted with the snap-in fitting portion 921. Exemplarily, one of the snap-in fitting portion 912 and the snap-in fitting portion 921 here can be a spring ball, and the other can be a slot; the snap-in seat 911 can be provided on the tray 910 through an elastic member, and the snap-in seat 911 pressed by the telescopic member 630 can be reset by the elastic member.

[0104] Here, the cap plate 920 can be more stably connected to the multiple battery cylinders through the snap-fitting between the cap plate 920 and the tray 910, and the battery cylinders can be stably arranged on the tray 910 to prevent the battery cylinders from shaking during transportation and detaching from the tray 910.

[0105] The battery cover manipulation device also includes a telescopic member 630, which is connected to the picking device 300. The telescopic member 630 can be extended to allow the snap-in seat 911 to slide downward, thereby causing the snap-in portion 912 to disengage from the snap-in mating portion 921. That is to say, after the picking device 300 picks up the cap plate 920, the telescopic member 630 and the snap-in seat 911 are arranged relative to each other in the vertical direction.

[0106] 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, since the cap plate 920 and the tray 910 are locked by the clamping portion 912 and the clamping matching portion 921, if the cap plate 920 is directly lifted upward at this time, the tray 910 and the battery cylinder body located therein will also move upward, which will cause the cap plate 920 to be unable to be separated from the battery cylinder body. Therefore, it is necessary to use the telescopic member 630 of this embodiment to disengage the clamping portion 912 and the clamping matching portion 921 from the clamping state, that is, control the telescopic member 630 to extend to press the clamping seat 911, so that the clamping seat 911 slides downward, at this time, the clamping portion 912 on the clamping seat 911 will disengage the clamping matching portion 921 on the cap plate 920, so that the cap plate 920 can be separated from the battery cylinder body by lifting the cap plate 920 upward.

[0107] In some embodiments, see Figure 5 and Figure 6The battery cover manipulation device further includes a substrate 650, the telescopic member 630 and the picking device 300 are both disposed on the substrate 650, the hooking portion 321 of the picking rod 320 is located below the substrate 650, the first driving member 310 can be disposed on the upper surface of the substrate 650, and the driving device 400 is connected to the substrate 650 and can drive the substrate 650 to move in the vertical direction. It should be noted that when the battery cover manipulation device is used to cover the battery cover, the portion of the picking device 300 located above the cap plate 920 can be pressed against the cap plate 920 through the substrate 650 to achieve connection between the cap plate 920 and the battery barrel.

[0108] In a further embodiment, the battery cover operating device also includes a collision sensor 660, which is connected to the substrate 650 and is located on the peripheral side 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 time.

[0109] In an alternative embodiment, see 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, a roller conveyor, a chain conveyor, etc. The first conveying device 120 is connected to the frame body 110. The conveying direction of the first conveying device 120 ( Figure 2 The first station 101 is located above the first conveying device 120, which is used to carry the tray 910 on which multiple battery barrels are placed, and can convey the tray 910 toward the first station 101. Specifically, the first conveying device 120 of this embodiment can be connected to an external conveying line, that is, the tray 910 conveyed by the external conveying line can be conveyed to the first conveying device 120, and then conveyed to the first station 101 by the first conveying device 120.

[0110] See also Figure 2 and Figure 3 The battery cover manipulation device further 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, the first positioning member 720 is located outside the first station 101, and the second driving member 710 can drive the first positioning member 720 to move toward the first station 101, so that the first positioning member 720 is positioned and matched with the tray 910 provided on the first conveying device 120, and the tray 910 is located at the first station 101. Exemplarily, the first positioning member 720 and the second driving member 710 can be located below, to the side or above the first station 101, and this application is not limited thereto.

[0111] In this embodiment, the first positioning member 720 is located outside the first station 101, which can prevent the first conveying device 120 from interfering with the tray 910 during the process of conveying the tray 910. After the first conveying device 120 conveys the tray 910 to a position close to the first station 101, the second driving member 710 can drive the first positioning member 720 to move toward the first station 101, so that the first positioning member 720 is positioned and matched with the tray 910, thereby correcting the position of the tray 910 so that it is accurately located in the first station 101, so that the picking device 300 can pick up the cap plate 920; and it is beneficial for the force-applying device 200 to fix each battery cylinder on the frame 100.

[0112] 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 workstation 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 workstation 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 workstation 101.

[0113] When the conveying stroke of the first conveying device 120 is too large and causes the pallet 910 to exceed the first station 101, the first guide surface of the first push block 721 will contact the portion of the pallet 910 that exceeds the first station 101 during the movement of the first push block 721 toward the first station 101, thereby causing 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 driving member 710 continues to drive the first positioning member 720 to approach the first station 101, the positioning pin 722 will cooperate with the pallet 910 to position the pallet 910, so that the pallet 910 is accurately located in the first station 101.

[0114] Furthermore, the first positioning member 720 also includes a second push block, the first workstation 101 is located on one side of the second push block along the conveying direction of the first conveying device 120, and the second push block has a second guide surface, and the second guide surface is inclined toward the first edge of the first workstation 101 in the opposite direction of the conveying direction of the first conveying device 120.

[0115] When the conveying stroke of the first conveying device 120 is too small and the pallet 910 has not completely entered the first workstation 101, the first guide surface will contact the portion of the pallet 910 that has not entered the first workstation 101, thereby moving the pallet 910 along the conveying direction of the first conveying device 120 to position the pallet 910 in the conveying direction of the first conveying device 120.

[0116] In some embodiments, a stop block 140 is provided on the frame 100 , and the stop block 140 is located on one side of the first workstation 101 along the conveying direction of the first conveying device 120 .

[0117] In an alternative embodiment, see Figure 4 The frame 100 further includes a second conveying device 130 spaced apart from the first conveying device 120 in the horizontal direction. The second conveying device 130 is connected to the frame body 110. The conveying direction of the second conveying device 130 is ( Figure 4 The second workstation 102 is located above the second conveying device 130, which is used to carry the tray 910 on which the cap plate 920 is placed, and can convey the tray 910 toward the second workstation 102. Exemplarily, 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 workshop production line and facilitating the layout of the factory; 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 is not limited thereto.

[0118] Please continue reading Figure 4 The battery cover manipulation 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, and the second positioning member 820 is located outside the second station 102. The third driving member 810 can drive the second positioning member 820 to move toward the second station 102, so that the second positioning member 820 is positioned and matched with the tray 910 provided on the second conveying device 130, and the tray 910 is located at the second station 102, so that the picking device 300 can accurately grab the cap plate 920. It should be noted that the structure of the second positioning member 820 here can be the same as the structure of the first positioning member 720, and this application will not repeat it.
