Description

Technical Field

[0001] The present application relates to the field of batteries, and in particular to a battery gripping device and a battery production system. Background Art

[0002] During the battery assembly process, the batteries need to be transferred to a set station. The transfer equipment is usually equipped with multiple grippers, which can simultaneously grip and transfer multiple batteries. However, when the number of batteries changes, the battery gripper cannot adapt quickly, which affects production capacity. Utility Model Content

[0003] In view of the above problems, the present application provides a battery gripping device and a battery production system to improve production capacity.

[0004] The present application provides a battery gripping device, comprising a first frame, two clamping jaw assemblies and a limiting member. The two clamping jaw assemblies are connected to the first frame and are arranged opposite to each other in a first direction. Each clamping jaw assembly comprises a plurality of clamping jaws arranged at intervals in a second direction. The two clamping jaws arranged opposite to each other of the two clamping jaw assemblies are used to clamp the battery. Each of the plurality of clamping jaws is slidably arranged in the second direction relative to the first frame. The limiting member is detachably arranged on the first frame and the limiting member has a connected state and a separated state. In the connected state, the limiting member is connected to the first frame to limit the position of each clamping jaw in the second direction. In the separated state, the limiting member is separated from the first frame, and at least part of the plurality of clamping jaws is configured to be slidable relative to the first frame and leave the first frame to adjust the number of clamping jaws installed on the first frame.

[0005] In the technical solution of the embodiment of the present application, at least part of the jaws of the jaw assembly of the battery gripping device can slide relative to the first frame, so that after the limiting member is separated from the first frame, the number of jaws installed on the first frame can be reduced by sliding part of the jaws away from the first frame, or the number of jaws installed on the first frame can be increased by sliding part of the jaws to be installed on the first frame. Therefore, the battery gripping device of the embodiment of the present application can simply and efficiently set the number of jaws installed on the first frame according to needs, and after adjusting the number of jaws, the multiple jaws are limited by the limiting member so that the number of jaws corresponds to the number of batteries to be grasped. There is no need to disassemble all the multiple jaws and then adjust the installation number of each jaw according to the number of batteries, which shortens the time spent on replacing the jaws, improves the replacement efficiency, and thus increases production capacity.

[0006] In some embodiments, the battery gripping device further comprises two slide rails disposed on the first frame and corresponding to the two clamping jaw assemblies, each slide rail extending along the second direction, and each clamping jaw being configured to slide with the slide rail. The use of the slide rails can realize rapid replacement and position adjustment of the clamping jaws at a relatively low cost.

[0007] In some embodiments, the position limiting member includes a main body and a plurality of separation grooves, the plurality of separation grooves are arranged at intervals along the second direction on the main body, and in the connected state, the plurality of clamps are correspondingly located in the plurality of separation grooves to limit the position of each clamp. The position limiting member can separate and limit the plurality of clamps on the slide rail, so that the position of each clamp relative to the first frame on the slide rail is fixed, thereby improving the stability of the battery grabbing device after grabbing the battery.

[0008] In some embodiments, the battery gripping device includes a plurality of limit members, and the number of separation grooves of each of the plurality of limit members is different to match the number of jaws installed on the first frame. The battery gripping device of the embodiment of the present application is provided with a plurality of limit members, and the plurality of limit members can be selectively connected to the first frame, so that after the number of jaws installed on the first frame is adjusted by sliding some of the jaws relative to the first frame, the limit members corresponding to the number of separation grooves and the number of jaws can be connected to the first frame, thereby achieving the function of limiting the plurality of jaws of the jaw assembly, and further improving the replacement efficiency of the battery gripping device. Moreover, such a setting eliminates the need to prepare different mounting plates for different numbers of jaws, thereby reducing costs.

[0009] In some embodiments, the spacing between adjacent separation grooves of each of the plurality of limiting members is different. When the batteries to be grasped are arranged at different spacings, the arrangement of the plurality of clamps in the battery grasping device can be well adapted to the batteries through different limiting members, thereby reliably grasping the plurality of batteries, thereby improving the adaptability of the battery grasping device.

[0010] In some embodiments, the plurality of separation grooves of the position-limiting member are distributed at equal intervals. In this way, the plurality of jaws of the clamping jaw assembly are arranged corresponding to the positions of the plurality of batteries arranged at equal intervals. Moreover, the plurality of separation grooves of the position-limiting member are distributed at equal intervals so that after the clamping jaw assembly grabs the plurality of batteries, the intervals between the plurality of batteries are equalized, thereby improving the force uniformity of the first frame and reducing the vibration and dislocation caused by the unbalanced force.

[0011] In some embodiments, the clamp includes a clamp mounting plate and a clamping portion disposed on the clamp mounting plate, the clamp mounting plate is slidably connected to the first frame, and the clamping portion is used to clamp the battery. The structure is simple, the manufacturing cost is low, and the clamp mounting plate is easy to be removed from the slide rail, thereby improving the convenience of disassembly of the clamp.

[0012] In some embodiments, the battery gripping device further includes a second frame, the second frame is detachably connected to the first frame, and the second frame is used to connect to the robotic arm so that the robotic arm drives the battery gripping device to move.

[0013] In some embodiments, the second frame has a flange joint, and the flange joint is used to connect the mechanical arm, so as to improve the stability of the connection.

[0014] In some embodiments, the second rack is connected to the first rack via a quick-change mechanism, which can increase the speed of assembly and disassembly of the first rack and the second rack, shorten assembly time, and thus increase production capacity.

[0015] In some embodiments, the battery gripping device further includes a visual camera disposed on the second rack, the visual camera being used to obtain the position of the first rack during the process of docking and installing the second rack with the first rack. The visual camera can improve the accuracy of disassembly and assembly between the first rack and the second rack.

[0016] The second aspect of the present application provides a battery production system, including the battery gripping device as described above. Based on the battery production system provided by the present application, the transportation efficiency of the battery transportation link can be improved, thereby increasing the battery output.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0036] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0037] During the research process, the applicant of this application discovered that in the prior art, multiple jaws are fixed on a mounting plate by bolts. When the number of batteries to be transported changes, since the number of jaws does not match the number of batteries, all the jaws need to be disassembled, and the mounting plate matching the number of batteries needs to be replaced, and the spacing between the jaws needs to be adjusted. This process is rather cumbersome and inefficient, which seriously affects the production capacity of the equipment.

[0038] Based on the above technical problems, the applicant has found that during the production process, when the number of batteries changes, if the number of jaws can be adjusted without replacing the mounting plate, the time spent on the jaw replacement process will be significantly shortened, thereby increasing the equipment's production capacity.

[0039] refer to Figure 1 and 2An embodiment of the present application provides a battery gripping device, comprising a first frame 01, two clamping jaw assemblies 02 and a limiting member 04. The two clamping jaw assemblies 02 are connected to the first frame 01 and are arranged opposite to each other in a first direction Y. Each clamping jaw assembly includes a plurality of clamping jaws arranged at intervals in a second direction X. The two clamping jaws arranged opposite to each other of the two clamping jaw assemblies 02 are used to clamp the battery. Each of the plurality of clamping jaws is slidably arranged in the second direction X relative to the first frame 01. The limiting member 04 is detachably arranged on the first frame 01 and the limiting member 04 has a connected state and a separated state. In the connected state, the limiting member 04 is connected to the first frame 01 to limit the position of each clamping jaw in the second direction X. In the separated state, the limiting member 04 is separated from the first frame 01, and at least part of the plurality of clamping jaws is configured to be slidable relative to the first frame 01 and leave the first frame 01 to adjust the number of clamping jaws installed on the first frame 01.

[0040] Specifically, when the limiting member 04 is in the separated state, since the multiple jaws in the jaw assembly 02 are not limited in the second direction X, they are all in an active state that can slide relative to the first frame 01 in the second direction X under the action of an external force. In other words, in this state, by applying a force in the second direction X to some of the multiple jaws, the jaws can slide to the end of the first frame 01 along the second direction X and detach from the first frame 01, thereby removing the jaws from the first frame 01, and then adjusting the number of jaws installed on the first frame 01. After adjusting the number of jaws, the limiting member 04 is reinstalled so that the limiting member 04 limits the remaining jaws, and the adjustment of the number of jaws of the battery gripping device is completed.

[0041] In some embodiments, the battery includes a battery cell. The battery cell includes a housing, an end cap, and an electrode assembly disposed in the housing. The end cap covers the opening of the housing to isolate the internal environment of the battery cell from the external environment. The electrode assembly is a component in the battery cell where an electrochemical reaction occurs. In some embodiments, the battery may also include a battery module. The battery module includes a plurality of battery cells.

[0042] Therefore, in the technical solution of the embodiment of the present application, at least part of the jaws of the jaw assembly 02 of the battery gripping device can slide relative to the first frame 01, so that after the limit member 04 is separated from the first frame 01, the number of jaws installed on the first frame 01 can be reduced by sliding part of the jaws away from the first frame 01, or the number of jaws installed on the first frame 01 can be increased by sliding part of the jaws to be installed on the first frame 01. Therefore, the battery gripping device of the embodiment of the present application can simply and efficiently adjust the number of jaws installed on the first frame 01 according to needs. After adjusting the number of jaws, the plurality of jaws are limited by the limit member 04 so that the number of jaws corresponds to the number of batteries to be gripped. There is no need to disassemble all the plurality of jaws and then adjust the installation number of each jaw according to the number of batteries. This shortens the time spent on replacing the jaws, improves the replacement efficiency, and thus increases production capacity.

[0043] In some embodiments, the battery gripping device further includes two slide rails 03 disposed on the first frame 01 and corresponding to the two clamping jaw assemblies 02 . Each slide rail 03 extends along the second direction X. Each clamping jaw is configured to slide with the slide rail 03 .

[0044] Specifically, no blocking structure is set at both ends of the slide rail 03 in the second direction X. Therefore, when the limit member 04 is in a separated state, the clamp can slide smoothly through the slide rail 03 under the drive of external force, so that the clamp can slide to the end of the slide rail 03 and detach from the slide rail 03.

[0045] The use of the slide rail 03 can realize the rapid replacement and position adjustment of the clamping jaws at a relatively low cost. Specifically, when the number of clamping jaws needs to be reduced, the clamping jaws can be slid along the slide rail 03 and pulled out from the end of the slide rail 03. When the number of clamping jaws needs to be increased, the clamping jaws can be assembled from the end of the slide rail 03 in the same way. The disassembly and installation process of the clamping jaws are simple and convenient.

[0046] refer to Figure 4 In some embodiments, the position limiting member 04 includes a main body 41 and a plurality of separation grooves 42. The plurality of separation grooves 42 are arranged on the main body 41 at intervals along the second direction X. In the connected state, the plurality of clamps are correspondingly located in the plurality of separation grooves 42 to limit the position of each clamp.

[0047] Specifically, when the battery grasping device grasps the battery, the limit member 04 is in a connected state. At this time, the limit member 04 can separate and limit the multiple claws on the slide rail 03, so that the position of each claw on the slide rail 03 is fixed relative to the first frame 01, thereby improving the stability of the battery grasping device after grasping the battery.

[0048] It is understandable that, since the battery gripping device has two relatively arranged jaw assemblies 02, when the battery gripping device grips the battery, the number of the limiting members 04 is also two, and the two limiting members 04 limit the two jaw assemblies 02 respectively. The limiting members 04 are respectively connected to the two sides of the first frame 01 to act on each jaw in the two jaw assemblies 02 respectively. Usually, the number of jaws in the two jaw assemblies is the same, that is, the number of separation grooves 42 of the two limiting members 04 is also the same. Since a single jaw assembly 02 is limited by a single limiting member 04, in some cases, the number of jaws in the jaw assembly 02 on one side can also be adjusted separately according to demand. At this time, the number of separation grooves 42 of the limiting members 04 on both sides is different, thereby increasing the flexibility of adjusting the number of jaws.

[0049] In some embodiments, the battery gripping device includes a plurality of stoppers 04. The number of separation slots 42 of each of the plurality of stoppers 04 is different to match the number of clamping claws 03 installed on the first frame 01.

[0050] The battery gripping device of the embodiment of the present application is provided with a plurality of limiters, which can be selectively connected to the first frame 01. In this way, after the number of jaws installed on the first frame is adjusted by sliding some of the jaws relative to the first frame 01, the limiters corresponding to the number of separation slots 42 and the number of jaws can be connected to the first frame 01, thereby achieving the function of limiting the multiple jaws of the jaw assembly 02, and further improving the replacement efficiency of the battery gripping device. Moreover, such a setting does not require the preparation of different mounting plates for different numbers of jaws, thereby reducing costs. For example, when the number of batteries to be gripped decreases, the limiter 04 is first removed, and then some of the jaws are pulled away from the slide rail 03, and then the limiter with the number of separation slots 42 matching the current number of jaws is selected from the plurality of limiters 04, and the limiter is installed on the first frame 01. After installation, the limiter 04 separates and limits each jaw.

[0051] In some embodiments, the plurality of separation grooves 42 of the limiting member 4 are distributed at equal intervals.

[0052] Such arrangement enables the multiple jaws of the jaw assembly to be arranged corresponding to the positions of the multiple batteries arranged at equal intervals. Moreover, the multiple dividing grooves of the limiting member are evenly spaced, so that after the jaw assembly grabs multiple batteries, the intervals between the multiple batteries can be equalized, thereby improving the force uniformity of the first frame 01 and reducing the vibration and misalignment caused by unbalanced force. When the number of batteries to be grabbed decreases, some of the jaws are disassembled and the corresponding limiting member 04 is installed. At this time, since the dividing grooves 42 are evenly spaced, the spacing between the jaws will increase under the action of the dividing grooves 42, because a smaller number of jaws are evenly distributed on the slide rail 03, and then after grabbing multiple batteries, the spacing between the batteries will also increase accordingly.

[0053] In some embodiments, the spacing between adjacent dividing grooves 42 of each of the plurality of limiting members is different.

[0054] For example, when the number of batteries to be grasped decreases, some of the clamps are disassembled and the corresponding limiters 04 are installed. At this time, since the partition grooves 42 are evenly spaced, the spacing between the clamps will increase under the action of the partition grooves 42, because a smaller number of clamps are evenly distributed on the slide rail 03, and after grasping multiple batteries, the spacing between the batteries will also increase accordingly. In this way, when the batteries to be grasped are arranged at different intervals, different limiters can be used to make the arrangement of multiple clamps in the battery grasping device better adapt to the batteries, so that multiple batteries can be grasped reliably, thereby improving the adaptability of the battery grasping device.

[0055] refer to Figure 4 and 5 In some embodiments, the clamp includes a clamp mounting plate 21 and a clamping portion 23 disposed on the clamp mounting plate 21. The clamp mounting plate 21 is slidably connected to the frame 01. The clamping portion 23 is used to clamp the battery.

[0056] Such an arrangement makes the clamp structure simple, the manufacturing cost is low, and it is easy to remove the clamp mounting plate 21 from the slide rail 03, thereby improving the convenience of disassembly of the clamp.

[0057] The size of the separation groove 42 and the clamping jaw mounting plate 21 in the second direction X is substantially the same, so that the separation groove 42 limits the clamping jaw mounting plate 21. The clamping jaw includes a slider 22 disposed on the clamping jaw mounting plate 21, and the clamping jaw mounting plate 21 forms a sliding fit with the slider 03 through the slider 22, thereby improving the smoothness of the movement of the clamping jaw on the slide rail 03.

[0058] Further, refer to Figure 5, each of the two slide rails 03 may include a first sub-slide rail 3a and a second sub-slide rail 3b that are spaced apart and arranged in parallel in the first direction Y. The first sub-slide rail 3a is farther away from the central axis of the first frame 01 along the height direction Z than the second sub-slide rail 3b. Correspondingly, the slider 22 includes a first sub-slide rail 22a and a second sub-slide rail 22b that are spaced apart and arranged in parallel in the first direction Y. The first sub-slide rail 22a is farther away from the central axis of the first frame 01 along the height direction Z than the second sub-slide rail 22b. The first sub-slide rail 3a and the first sub-slide rail 22a correspond in position. The second sub-slide rail 3b and the second sub-slide rail 22b correspond in position. In this way, the stability of the clamp during movement can be improved.

[0059] In some embodiments, the battery gripping device further comprises two cam plates relatively arranged on the first frame 01. The two cam plates are arranged to move toward each other under the action of a driving element (e.g., a cylinder). The two clamping jaw assemblies are respectively arranged on the two cam plates. By controlling the two cam plates to move toward each other, the two clamping jaw assemblies can be moved toward each other, thereby shortening the distance between the clamping jaws in the two clamping jaw assemblies, thereby achieving the gripping of the battery.

[0060] In order to improve the stability of the gripper to grasp the battery, refer to Figure 5 In some embodiments, the clamp includes a bending plate. The bending plate includes a first extension section extending along a first direction Y and a second extension section extending along a height direction Z. The first extension section is used to connect with the clamp mounting plate 21. The second extension section is used to clamp the battery. Such a configuration can increase the contact area between the clamp and the battery, increase the friction force, and improve the stability of the grip.

[0061] refer to Figure 2 In some embodiments, the battery gripping device further includes a second frame 05. The second frame 05 is detachably connected to the first frame 01, and the second frame 05 is used to connect to the robot arm so that the robot arm drives the battery gripping device to move.

[0062] The first rack 01 and the second rack 05 are detachably arranged to improve the flexibility of the battery gripping device, and facilitate the separate replacement or repair of the first rack 01 or the second rack 05. It is also convenient to separately expand and transform the first rack 01 or the second rack 05, thereby improving the expansibility of the battery gripping device.

[0063] In some embodiments, the second frame 05 has a flange joint A. The flange joint A is used to connect the robot arm, so as to improve the stability of the connection.

[0064] In some embodiments, the second rack 05 is connected to the first rack 01 via a quick-change mechanism. The quick-change mechanism can increase the speed of disassembly and assembly of the first rack 01 and the second rack 05, shorten the assembly time, and thus increase production capacity. The quick-change mechanism includes a quick-change disk, wherein the quick-change disk includes a male disk 91 and a female disk 92, and the male disk 91 and the female disk 92 are respectively arranged on the first rack 01 and the second rack 05.

[0065] refer to Figure 3 In some embodiments, the battery grasping device further includes a visual camera B disposed on the second rack. The visual camera B is used to obtain the position of the first rack 01 during the process of docking and installing the second rack with the first rack 01.

[0066] The visual camera B can improve the accuracy of assembly and disassembly between the first rack 01 and the second rack 05. For example, when assembling the first rack 01 and the second rack 05, usually, the second rack 05 is in a fixed connection with the robot arm, and the first rack 01 is transported by the transportation mechanism. Specifically, during the installation process, the transportation mechanism first transfers the first rack 01 to the designated area. At this time, the visual camera B identifies the specific position of the first rack 01 and feeds back to the controller. The controller controls the robot arm to drive the second rack 05 to move to the position of the first rack 01 according to the recognition result of the visual camera B, and then completes the connection through the quick-change disk. At this point, the assembly of the first rack 01 and the second rack 05 is achieved accurately and quickly.

[0067] Similarly, when splitting the first rack 01 and the second rack 05, the transport mechanism is first controlled to move to the designated area, and then the visual camera B identifies the specific position of the transport mechanism and feeds it back to the controller. The controller controls the robotic arm to drive the battery grabbing device to move to the position of the transport mechanism based on the recognition result of the visual camera B, and then splits the first rack 01 and the second rack 05 through the quick-change disk, and the transport mechanism takes over the first rack 01. At this point, the splitting of the first rack 01 and the second rack 05 is achieved accurately and quickly.

[0068] In some embodiments, the transport mechanism includes a work cart.

[0069] In order to improve the functionality of the battery gripping device, in some embodiments, the battery gripping device further includes a solenoid valve row 06. The solenoid valve row 06 is disposed on the second frame 05. The solenoid valve row 06 is integrated with a plurality of solenoid valves for controlling pneumatic components, such as cylinders.

[0070] In order to improve the safety of the battery gripping device, refer to Figure 1 and 2In some embodiments, the battery gripping device further includes a bottom-covering mechanism 07. The bottom-covering mechanism 07 is detachably connected to the second frame 05 and is disposed around the circumference of the second frame 05. The bottom-covering mechanism 07 is used to abut the battery from the lower side of the battery after the clamping claw assembly grabs the battery, thereby reducing the risk of the battery falling off the clamping claw.

[0071] refer to Figure 3 In order to further improve the functionality of the battery gripping device, in some embodiments, the battery gripping device further includes a communication module 08. The communication module 08 is disposed on the second rack 05. The communication module is connected to a plurality of external devices (for example, including various sensors and actuators, etc.) by signals, and is used to output signals to the plurality of external devices, or to receive signals from the plurality of external devices.

[0072] The embodiment of the present application also provides a battery production system, including the battery gripping device as described above. Based on the battery production system provided by the present application, the transportation efficiency of the battery transportation link can be improved, thereby increasing the battery output.

[0073] In some embodiments, the battery grasping device includes a first frame 01, a second frame 05, two clamping jaw assemblies 02, two slide rails 03, a plurality of limit members 04, a solenoid valve row 06, a bottom-covering mechanism 07, a communication module 08, and a visual camera B. The first frame 01 and the second frame 05 are connected by a quick-change disk. A flange joint A is provided on the second frame 05, and the second frame 05 is connected to a robotic arm through the flange joint A, and the robotic arm is used to drive the battery grasping device to move. Two slide rails 03 are arranged oppositely on the first frame 01 and extend along the second direction X, and two clamping jaw assemblies 02 are connected to the first frame 01 through two slide rails 03 respectively, and the two clamping jaw assemblies 02 are arranged oppositely in the first direction Y. Each clamping jaw assembly includes a plurality of clamping jaws arranged at intervals in the second direction X. The two clamping jaws of the two clamping jaw assemblies 02 are used to clamp the battery. Each of the plurality of clamping jaws includes a mounting plate 21, a slider 22, and a clamping portion 23. The slider 22 and the clamping part 23 are both arranged on the clamping jaw mounting plate 21. The slider 22 is used to slide with the slider 03 to move the clamping jaw mounting plate 21 relative to the first frame 01. The limiter 04 includes a main body 41 and a plurality of partition grooves 42. Different limiters 04 have different numbers of partition grooves 42, and the spacing between adjacent partition grooves 42 is also different. The partition grooves 42 are used to limit the clamping jaw mounting plate 21. The solenoid valve row 06, the bottom support mechanism 07, the communication module 08 and the visual camera B are all arranged on the second frame 05.

[0074] When the number of jaws needs to be reduced, the original limiting members 04 for limiting the multiple jaws in the two jaw assemblies 02 are removed from the first frame 01, and then the number of jaws in the two jaw assemblies 02 is adjusted through the two slide rails 03. Next, the limiting members 04 matching the current number of jaws are selected and installed on the first frame 01, so as to separate and limit the existing jaws, and the rapid adjustment of the number of jaws is completed.

[0075] When the first rack 01 and the second rack 02 are separated, the tooling trolley can be controlled to move to the designated area, and the second rack 05 and the first rack 01 can be driven by the robot arm to move to the position corresponding to the tooling trolley, and the first rack 01 and the second rack 05 can be separated by the quick-change plate, and the tooling trolley can carry the first rack 01. During this process, the visual camera B can detect the position of the tooling trolley and feed back the detection results to the controller, and the controller controls the displacement accuracy of the robot arm according to the feedback results. The assembly process of the first rack 01 and the second rack 05 is similar to the disassembly process, which will not be repeated here.

[0076] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
