Description

Technical Field

[0001] This application relates to the field of battery production technology, and in particular to a tray and battery production equipment using the tray. Background Technology

[0002] In the battery production process, battery units are usually loaded and positioned using trays so that they can be moved between different processes.

[0003] However, in the use of the trays in related technologies, different robotic arms and other modules are required to grasp and place the battery devices during different process flows, and the positions of these different robotic arms and other modules are inaccurate. At the same time, the assembly and positioning consistency of the tray itself also has errors. Therefore, to facilitate accurate placement of the battery devices into the tray by the robotic arms, a fixed clearance is usually reserved between the tray and the battery devices to accommodate these errors. However, the existence of this clearance can cause the battery devices to move during the flow, thus affecting the positioning of the battery devices on the tray. Utility Model Content

[0004] The main objective of this application is to provide a tray designed to improve the positioning of battery devices.

[0005] To achieve the above objectives, the tray proposed in this application includes:

[0006] The tray body is configured to hold the battery device;

[0007] Stop, the stop is provided on the pallet body; and

[0008] The limiting mechanism includes a limiting member, which is movably disposed on the pallet body. The limiting member includes a driving part and a clamping part, and the clamping part and the stop are arranged at a relative interval.

[0009] The driving part is configured to be driven by the battery device to drive the clamping part to approach the stop and cooperate with the stop to clamp the battery device.

[0010] The technical solution of this application makes the limiting member in the limiting mechanism movable, and includes a driving part that can be driven by the battery device and a clamping part that is spaced apart from the stop. This allows for a larger distance between the clamping part and the stop when the tray is not loaded with battery devices, accommodating positional errors of modules such as robotic arms that unload battery devices, as well as assembly and positioning errors of the tray itself. In other words, it increases the tolerance for various errors, facilitating the smooth and accurate placement of the battery device between the stop and the clamping part by robotic arms and other modules, reducing the possibility of collisions. When the battery device is unloaded by the robotic arm and other modules and comes into contact with the driving part, it can drive the driving part to move, causing the clamping part to move closer to the stop, achieving a gripping gripping of the battery device by the clamping part and the stop. At this time, the clamping part and the battery device can fit tightly without gaps, ensuring that the battery device is always gripped by the stop and clamping part during the flow of the tray, thus improving the positioning effect of the tray on the battery device.

[0011] In some embodiments, the driving part is rotatably disposed on the tray body, and the clamping part is connected to the driving part;

[0012] The driving part is configured to be driven to rotate by the battery device, so as to drive the clamping part to rotate and approach the stop.

[0013] Therefore, the clamping part can move synchronously and stably with the driving part, which helps to improve the accuracy and stability of the clamping part in clamping the battery device.

[0014] In some embodiments, the driving part is provided with a support surface, which is configured to abut against the supporting battery device;

[0015] The clamping part is provided with a clamping surface, and the clamping surface and the stop are arranged opposite to each other. The clamping surface is configured to cooperate with the stop to clamp the battery device, and the support surface is located between the stop and the clamping surface.

[0016] This allows the battery device to abut against the driving part through gravity during feeding, and since the gravity of the battery device is constant, it can stably abut against the driving part, thereby improving the stability of the clamping part in abutting and holding the battery device.

[0017] In some embodiments, the driving part extends along the arrangement direction of the stop and the clamping part, and the clamping part is connected to the end of the driving part away from the stop and extends along the side facing the support surface.

[0018] This design results in a simpler and more compact structure for the limiting component, improving the ease of installation and arrangement of the limiting component on the tray body. Furthermore, positioning the clamping part at the end of the driving part away from the stop component allows for a longer clamping part, enabling a larger area of ​​contact between the driving part and the battery device, thereby enhancing the limiting effect of the limiting component on the battery device.

[0019] In some embodiments, the end of the driving part near the clamping part is rotatably connected to the tray body.

[0020] Therefore, the structure of the rotating part of the driving unit can better avoid the battery device, so that the battery device can effectively resist and drive the driving unit to rotate.

[0021] In some embodiments, in the arrangement direction of the stop and the clamping part, the clamping part is disposed closer to the stop relative to the rotation axis of the driving part;

[0022] And / or, the driving part includes a first segment and a second segment connected to each other and arranged at an angle, one end of the first segment is rotatably disposed on the tray body, and the other end extends in the direction close to the stop member; part of the support surface is disposed on the first segment and the other part is disposed on the second segment, and the clamping part is connected to the end of the first segment away from the second segment.

[0023] Therefore, by placing the clamping part on the side of the rotating axis of the driving part close to the stop member, the structural clearance effect of the rotating part of the driving part on the battery device can be further improved, so that the battery device can effectively abut against the driving part to rotate. At the same time, the fitting and abutting effect of the angle between the driving part and the clamping part on the battery device can be enhanced, thereby improving the limiting effect of the limiting member on the battery device. Furthermore, by setting the driving part to include a first segment and a second segment at an angle, the contact area between the driving part and the battery device can be maximized while maintaining a relatively compact structure, thereby improving the stability of the abutment between the two and, consequently, improving the stability of the clamping part's abutment and clamping of the battery device.

[0024] In some embodiments, the support surface is a plane;

[0025] And / or, the clamping surface is a plane;

[0026] And / or, the clamping part protrudes from the support surface;

[0027] And / or, the clamping part and the driving part are integrated into one structure;

[0028] And / or, the limiting mechanism further includes a first buffer pad, at least a portion of which is disposed on the support surface;

[0029] And / or, the limiting mechanism further includes a second buffer pad, at least a portion of which is disposed on the clamping surface.

[0030] Therefore, setting the support surface as a plane increases the contact area with the battery device, which in turn helps to further improve the stability of the contact between the driving part and the battery device; setting the clamping surface as a plane increases the contact area with the battery device, which in turn helps to further improve the stability of the clamping part in contacting and clamping the battery device; making the clamping part directly protrude from the support surface helps to improve the compactness of the overall structure of the limiting member and reduces the possibility of interference and collision with modules such as the robot arm; making the clamping part and the driving part into one piece can improve the overall strength of the limiting member; the setting of the first buffer pad and the second buffer pad can reduce the possibility of the limiting member damaging the surface of the battery device.

[0031] In some embodiments, the limiting mechanism further includes an elastic element disposed between the driving part and the tray body, the elastic element being configured to drive the driving part to rotate and reset when the driving part and the battery device are separated.

[0032] Therefore, by setting up an elastic element, the drive unit can be automatically reset so that the pallet can be used for the next feeding.

[0033] In some embodiments, the limiting mechanism further includes a mounting member disposed on the pallet body, a driving part rotatably disposed on the mounting member, and an elastic member disposed between the driving part and the mounting member.

[0034] This improves the ease of installation and arrangement of the drive unit and elastic components.

[0035] In some embodiments, the driving part has a support surface and a back surface, the support surface is configured to abut against the support battery device, and the back surface is disposed away from the support surface.

[0036] The mounting component is located on the side of the drive unit facing away from the back, and the elastic component is located between the back-side and the mounting component.

[0037] This reduces the overall size of the limiting mechanism, further improving the structural compactness. Simultaneously, the distributed drive and mounting components allow for easier placement of elastic elements between them.

[0038] In some embodiments, the mounting member has a first receiving groove on the side facing away from the opposite side, and the end of the elastic member away from the opposite side is received in the first receiving groove.

[0039] And / or, a second receiving groove is provided on the opposite side, and one end of the elastic member near the opposite side is received in the second receiving groove;

[0040] And / or, the elastic element is a spring.

[0041] Therefore, by placing one end of the elastic element in the first receiving groove and the other end in the second receiving groove, the elastic element can be limited, so that the elastic element can be stably installed between the driving part and the mounting part. Moreover, the structure of the first receiving groove and the second receiving groove is relatively simple, which is conducive to improving the convenience of limiting the installation of the elastic element between the mounting part and the driving part respectively. Setting the elastic element as a spring can improve the reset effect of the driving part, and at the same time improve the convenience of its installation arrangement.

[0042] In some embodiments, the limiting mechanism further includes a mounting member disposed on the pallet body, and the driving part is rotatably connected to the mounting member.

[0043] This improves the ease of installing and arranging the limiting components.

[0044] In some embodiments, the driving part is provided with a support surface, which is configured to abut against the supporting battery device, and the mounting member is located on the side of the driving part opposite to the support surface;

[0045] And / or, the mounting component is provided with a mounting groove, which extends along the arrangement direction of the stop and the clamping part and passes through the opposite sides of the mounting component, so that the driving part is rotated and installed in the mounting groove.

[0046] This improves the overall compactness of the limiting mechanism, while the installation groove enhances the stability of the limiting component's rotation.

[0047] In some embodiments, the mounting member is movably disposed on the pallet body along the arrangement direction of the stop member and the clamping part, and can be fixed relative to the pallet body, and the driving part is rotated and mounted on the mounting member.

[0048] This allows the position of the limiting element installed on the mounting piece to be moved and adjusted so that the tray can be adapted to different types and sizes of battery devices.

[0049] In some embodiments, the limiting mechanism further includes a drive member disposed on the tray body and configured to drive the mounting member to move.

[0050] Therefore, the mounting components can be moved and adjusted without disassembling them, which improves the convenience of adjusting the position of the mounting components.

[0051] In some embodiments, the drive element includes a lead screw rotatably disposed on the tray body and extending along the movement direction of the mounting element;

[0052] The mounting component is fitted onto the lead screw and threadedly connected to it. The lead screw is configured to move the mounting component when rotated.

[0053] This allows for stepless position adjustment of the mounting components by rotating the lead screw, enriching the position adjustment of the mounting components and further improving the applicability of the tray to battery devices of different types and sizes.

[0054] In some embodiments, the limiting mechanism further includes a locking ring, which is sleeved on the lead screw and threadedly connected to the lead screw, and the locking ring is located on the side of the mounting member away from the stop member;

[0055] And / or, the drive unit also includes a motor, which is located on the tray body and connected to a lead screw.

[0056] Therefore, the stop component is used for further limiting, which further improves the stability of the mounting component and the limiting component after they are moved and adjusted to the correct position; the motor can realize the automatic drive of the lead screw, thereby improving work efficiency.

[0057] In some embodiments, the limiting mechanism further includes a fixing member, which is disposed on the tray body, and the lead screw is rotatably mounted on the fixing member.

[0058] This improves the convenience of screw installation and layout.

[0059] In some embodiments, the fastener is provided with a limiting hole and a partition groove, the lead screw passes through the limiting hole, and the partition groove connects the inner side and the outer side of the limiting hole, so that the fastener can deform to clamp or release the lead screw.

[0060] The limiting mechanism also includes a first locking screw, which connects the two parts of the fixing member separated by the partition groove.

[0061] Therefore, after the installation component is moved into place by rotating the lead screw, the lead screw can be locked and limited by the first locking screw to reduce the rotation of the lead screw and thus reduce the stability of the installation component after it is adjusted into place.

[0062] In some embodiments, the fastener includes:

[0063] The first part is connected to the tray body and has a rotating hole through which the lead screw passes.

[0064] The second part, which is arranged along the extension direction of the lead screw and separate from the first part, is provided with a limiting hole and a partition groove, with the limiting hole and the rotating hole being arranged opposite to each other; and

[0065] Part Three connects Part One and Part Two.

[0066] This reduces the possibility of interference between the connection structure between the fastener and the tray body and the first locking screw, improving the convenience of their respective arrangements.

[0067] In some embodiments, the tray body is provided with scale markings along the movement direction of the mounting component.

[0068] This allows for the illustration of the moving position of the mounting components, thereby improving the accuracy of adjusting their position.

[0069] In some embodiments, the mounting element is provided with a scale indicator that is configured to align with a scale mark.

[0070] Therefore, the scale indication can provide more precise indication of the scale markings on the tray body, thereby further improving the accuracy of adjusting the position of the mounting components.

[0071] In some embodiments, the number of limiting mechanisms is two, and the two limiting mechanisms are arranged side by side with a gap between them.

[0072] This will help to further improve the stability of the battery device when mounted on the tray.

[0073] This application also proposes a battery production apparatus, including the aforementioned tray. Attached Figure Description

[0083] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0084] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0085] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0086] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0087] Currently, batteries are being used more and more widely in daily life and industry. They are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. As the application areas of batteries continue to expand, the market demand for them is also constantly increasing.

[0088] During battery production, battery units are typically loaded and positioned using pallets to facilitate their movement through different processes. These pallets usually have fixed retaining devices to limit the movement of the battery units.

[0089] However, in the use of the trays in related technologies, different robotic arms and other modules are required to grasp and place the battery devices during different process flows, and the positions of these different robotic arms and other modules are inaccurate. At the same time, there are also errors in the assembly and positioning consistency of the tray itself. Therefore, in order to facilitate the accurate placement of the battery devices into the tray by the robotic arms, a fixed clearance is usually reserved between the tray's limiting components and the battery devices to accommodate the corresponding errors. However, the existence of this clearance can cause the battery devices to move during the flow, thus affecting the positioning effect of the battery devices on the tray.

[0090] Therefore, based on the above considerations, in order to solve the problem of poor positioning effect of trays for battery devices in related technologies, this application proposes a novel tray. This tray innovatively sets the limiting member as movable and includes a driving part and a clamping part. The battery module abuts against the driving part, driving the clamping part to approach the stop member. This allows the clamping part to maintain a large distance from the stop member when no battery module is placed on the tray, thus tolerating errors such as positional errors of modules like robotic arms and assembly and positioning errors of the tray itself. This facilitates smooth and accurate loading of battery devices and prevents collisions. After the battery module is placed on the tray, the clamping part can be driven to approach and abut against the battery module, allowing the battery module loaded on the tray to be abutted and limited by the limiting member. This reduces the possibility of movement of the battery device during subsequent handling and improves the positioning effect of the tray on the battery device.

[0091] Furthermore, it should be noted that the tray proposed in this application can be used for loading and positioning battery devices. The battery device can be a single battery cell, which may include a housing and an electrode assembly disposed within the housing. The electrode assembly may include a positive electrode, a negative electrode, and a separator disposed between the positive and negative electrodes. Alternatively, the battery device can be a battery module, which may include at least two battery cells stacked in one direction. Or, the battery device may be a battery pack. Additionally, the tray proposed in this application can also be used for loading and positioning other products.

[0092] The structure of the tray proposed in this application will be explained and illustrated below:

[0093] Please refer to the reference. Figures 1 to 3 In one embodiment of this application, the tray 100 proposed in this application includes a tray body 10, a stop 30, and a limiting mechanism 50; the tray body 10 is configured to hold a battery device 300; the stop 30 is disposed on the tray body 10; the limiting mechanism 50 includes a limiting member 51, which is movably disposed on the tray body 10. The limiting member 51 includes a driving part 511 and a clamping part 513, which are disposed at a distance from the stop 30; the driving part 511 is configured to be driven by the battery device 300 to drive the clamping part 513 to approach the stop 30 and cooperate with the stop 30 to clamp the battery device 300.

[0094] The tray body 10 provides a placement space for the battery device 300. The tray body 10 can be a plate structure. Furthermore, when the tray 100 is in use, the tray body 10 can support the battery device 300 via its upper surface. In addition, the shape of the tray body 10 on the horizontal projection plane can be rectangular, square, or circular, etc.; this application does not limit the shape of the tray body 10.

[0095] The stop member 30 can be used to abut against one end of the battery device 300 to limit the movement of that end. Specifically, when the support direction (i.e., the vertical direction) of the tray body 10 on the battery device 300 is defined as the first direction, and the arrangement direction of the stop member 30 and the clamping part 513 is defined as a second direction intersecting the first direction, the stop member 30 can extend along a third direction, which intersects the first and second directions. In this case, the stop member 30 can be a plate structure, a column structure, or a single-piece structure; this application does not limit the structural type of the stop member 30. Alternatively, the stop member 30 can include at least two sub-segments, which can be spaced apart along a third direction. In this case, the sub-segments can be a plate structure, a column structure, or a single-piece structure; this application also does not limit the structural type of the sub-segments. Furthermore, the stop member 30 and the tray body 10 can be an integral structure to improve the overall strength of the tray 100. It should be noted that the integrated structure proposed in this application refers to the direct manufacturing of two parts into a single unit through an integral molding method, such as injection molding or casting. Of course, the stop 30 and the tray body 10 can also be separate components, which can then be connected by any connection method such as screws, snap-fit ​​connections, or welding.

[0096] The limiting mechanism 50 can be driven by the driving part 511 in the limiting member 51, which is abutted by the battery device 300, thereby driving the clamping part 513 to move towards the stop member 30. This allows the clamping part 513 to abut against the end of the battery device 300 away from the stop member 30, thus cooperating with the stop member 30 to clamp and limit the battery device 300 placed on the tray body 10. Figure 3As shown, the solid line indicates that the limiting member 51 is in a free state, that is, not clamped to the battery device 300; the dashed line indicates that the limiting member 51 is in a working state, that is, clamped to the battery device 300. The driving part 511 and the clamping part 513 can be directly connected as described below, and the driving part 511 is rotatable so that the battery device 300 abuts against and drives the driving part 511 to rotate, thereby causing the clamping part 513 to rotate and approach the stop member 30. For example, the battery device 300 can drive the driving part 511 to rotate around an axis parallel to a third direction, thereby driving the clamping part 513 to rotate synchronously and approach the battery device 300; or, the battery device 300 can drive the driving part 511 to rotate around an axis parallel to a first direction, thereby driving the clamping part 513 to rotate synchronously and approach the battery device 300. Of course, the driving part 511 and the clamping part 513 can also be configured to cooperate via inclined surfaces, and the driving part 511 can be slidably configured so that the battery device 300 abuts against and drives the driving part 511 to slide. Then, the inclined surface cooperation between the driving part 511 and the clamping part 513 further compresses and drives the clamping part 513 to slide closer to the stop member 30. For example, the battery device 300 can drive the driving part 511 to slide down in a first direction, and during the downward movement, the driving part 511 compresses the clamping part 513 via the inclined surface cooperation to slide closer to the battery device 300 in a second direction; or, the battery device 300 can drive the driving part 511 to slide in a third direction away from the battery device 300, and during the sliding movement, the driving part 511 compresses the clamping part 513 via the inclined surface cooperation to slide closer to the battery device 300 in a second direction. Therefore, the driving part 511 can be moved by the downward-facing wall of the battery device 300 under the weight of the battery device 300, or it can be moved by the side wall of the battery device 300. Furthermore, the driving part 511 can be a plate structure, a column structure, or a single-piece structure, etc., and this application does not limit the structural type of the driving part 511. Similarly, the clamping part 513 can be a plate structure, a column structure, or a single-piece structure, etc., and this application also does not limit the structural type of the clamping part 513.

[0097] The technical solution of this application makes the limiting member 51 in the limiting mechanism 50 movable, and includes a driving part 511 that can be driven by the battery device 300 and a clamping part 513 that is spaced apart from the stop member 30. When the tray 100 is not loaded with the battery device 300, there can be a large distance between the clamping part 513 and the stop member 30 to accommodate the positional error of the robot or other module that unloads the battery device 300 and the assembly and positioning error of the tray 100 itself. In other words, the fault tolerance space is increased for various errors, so that the robot or other module can smoothly and accurately place the battery device 300 between the stop member 30 and the clamping part 513, reducing the possibility of collision. When the battery device 300 is unloaded by a robot or other module and comes into contact with the driving part 511, it abuts against and drives the driving part 511 to move, thereby driving the clamping part 513 to move in a direction close to the stop member 30. This allows the clamping part 513 and the stop member 30 to cooperate in clamping the battery device 300. At this time, the clamping part 513 and the battery device 300 can fit tightly without forming gaps. This ensures that during the circulation of the tray 100 containing the battery device 300, the battery device 300 can always be clamped by the stop member 30 and the clamping part 513 without moving, thereby improving the positioning effect of the tray 100 on the battery device 300.

[0098] Please refer to the reference. Figures 1 to 3 In one embodiment of this application, the driving part 511 is rotatably disposed on the tray body 10, and the clamping part 513 is connected to the driving part 511; the driving part 511 is configured to be driven to rotate by the battery device 300 so as to drive the clamping part 513 to rotate and approach the stop member 30.

[0099] The rotation axis of the driving part 511 can be parallel to a third direction as described above, allowing the battery device 300 to abut against the driving part 511 via a downward-facing wall surface. Alternatively, the rotation axis of the driving part 511 can be parallel to a first direction as described above, allowing the battery device 300 to abut against the driving part 511 via a side wall surface facing a third direction. Furthermore, it should be noted that the driving part 511 can be directly rotatably mounted to the tray body 10, or it can be rotatably mounted to the mounting member 55 as described below, achieving indirect mounting to the tray body 10. Rotational mounting can be achieved by passing a connecting shaft through both; alternatively, one of the two components can have a insertion shaft, and the other a insertion hole, with the insertion shaft inserted into the insertion hole to achieve rotational mounting. This application does not limit the rotational mounting method of the driving part 511.

[0100] In this embodiment, the driving part 511 is configured to be rotatable, so that the clamping part 513 and the driving part 511 are connected. At this time, when the driving part 511 is abutted and driven by the battery device 300, the clamping part 513 can move synchronously and stably, which helps to improve the accuracy and stability of the clamping part 513 in clamping the battery device 300.

[0101] Please refer to the reference. Figure 1 , Figure 2 as well as Figure 4 In one embodiment of this application, the driving part 511 is provided with a support surface 5111, which is configured to abut against the battery device 300; the clamping part 513 is provided with a clamping surface 5131, which is disposed opposite to the stop member 30, and the clamping surface 5131 is configured to cooperate with the stop member 30 to clamp the battery device 300, and the support surface 5111 is located between the stop member 30 and the clamping surface 5131.

[0102] The support surface 5111 can be upward-facing to abut against the downward-facing wall surface of the protrusion 301 on the third-direction side wall of the battery device 300; alternatively, it can abut against the bottom surface of the tray body 10, ensuring that when the battery device 300 is placed on the tray body 10, it can gradually abut against the driving part 511 by its own weight. The support surface 5111 can be partially or entirely used to abut against the battery device 300. The clamping surface 5131, when the tray body 10 is not occupied by the battery device 300, can be inclined upwards towards the side where the stop member 30 is located. When the battery device 300 is fully placed on the tray body 10, the clamping surface 5131 can rotate to the side wall facing away from the stop member 30, cooperating with the stop member 30 to clamp the battery device 300. The supporting surface 5111 can be a plane or a curved surface. Similarly, the clamping surface 5131 can be a plane or a curved surface.

[0103] In this embodiment, the driving part 511 is provided with a support surface 5111 located between the stop member 30 and the clamping surface 5131, so that the battery device 300 can abut against the driving part 511 by gravity when the battery device 300 is unloaded. The gravity of the battery device 300 is constant, so it can abut against the driving part 511 stably, which helps to improve the stability of the clamping part 513 in abutting and clamping the battery device 300.

[0104] Please refer to the reference. Figure 1 , Figure 2 as well as Figure 4In one embodiment of this application, the driving part 511 extends along the arrangement direction of the stop member 30 and the clamping part 513, and the clamping part 513 is connected to the end of the driving part 511 away from the stop member 30 and extends along the side facing the support surface 5111.

[0105] On a projection plane perpendicular to a third direction, the projections of the driving part 511 and the clamping part 513 can form an L-shape. At this time, the clamping part 513 can be protruding on the support surface 5111 as described below, or it can be provided on the surface adjacent to the driving part 511 and the support surface 5111, ensuring that a portion protrudes from the support surface 5111.

[0106] In this embodiment, the driving part 511 and the clamping part 513 are configured as an L-shaped structure, which makes the structure of the limiting member 51 simpler and more compact, improving the convenience of installing the limiting member 51 on the tray body 10. Simultaneously, by positioning the clamping part 513 at the end of the driving part 511 away from the stop member 30, the clamping part 513 can have a longer dimension in the second direction, allowing for a larger area of ​​contact between the driving part 511 and the battery device 300, thereby improving the limiting effect of the limiting member 51 on the battery device 300. Of course, this application is not limited to this; in other embodiments, the driving part 511 can also be configured as an arc shape or other shapes.

[0107] Please refer to the reference. Figure 2 and Figure 4 In one embodiment of this application, the end of the driving part 511 near the clamping part 513 is rotatably connected to the tray body 10.

[0108] In this embodiment, the end of the driving part 511 with the clamping part 513 is rotatably connected, which allows the structure of the rotating part of the driving part 511 (i.e., the combination of the connecting shaft or the insertion shaft and the insertion hole as described above) to better avoid the battery device 300, so that the battery device 300 can effectively abut against and drive the driving part 511 to rotate.

[0109] Please refer to the reference. Figure 1 , Figure 2 as well as Figure 4 In one embodiment of this application, in the arrangement direction of the stop member 30 and the clamping part 513, the clamping part 513 is disposed closer to the stop member 30 than the rotation axis of the driving part 511.

[0110] In this embodiment, the clamping part 513 is positioned on the side of the rotation axis of the driving part 511 close to the stop member 30. This can further improve the avoidance effect of the structure at the rotation point of the driving part 511 on the battery device 300, so that the battery device 300 can effectively abut against and drive the driving part 511 to rotate. At the same time, it enhances the fit and abutment effect of the angle between the driving part 511 and the clamping part 513 on the battery device 300, thereby improving the limiting effect of the limiting member 51 on the battery device 300.

[0111] Please refer to Figure 2 In one embodiment of this application, the driving part 511 includes a first segment 5115 and a second segment 5116 connected to each other and arranged at an angle. One end of the first segment 5115 is rotatably disposed on the tray body 10, and the other end extends in a direction close to the stop member 30. A portion of the support surface 5111 is disposed on the first segment 5115, and another portion is disposed on the second segment 5116. The clamping part 513 is connected to the end of the first segment 5115 away from the second segment 5116.

[0112] The first segment 5115 can be extended along a second direction. The second segment 5116 can be extended along a third direction.

[0113] In this embodiment, the driving part 511 is configured to include a first segment 5115 and a second segment 5116 at an angle. This allows the driving part 511 to have a relatively compact structure while maximizing the contact area with the battery device 300, improving the stability of their contact, and consequently enhancing the stability of the clamping part 513 in clamping the battery device 300. Of course, in other embodiments, the driving part 511 may only include the first segment 5115.

[0114] Please refer to Figure 4 In one embodiment of this application, the support surface 5111 is a plane.

[0115] In this embodiment, the support surface 5111 is set as a plane, which can increase the contact area with the battery device 300, thereby further improving the stability of the contact between the driving part 511 and the battery device 300.

[0116] Please refer to Figure 4 In one embodiment of this application, the clamping surface 5131 is a plane.

[0117] In this embodiment, the clamping surface 5131 is set as a plane, which can increase the contact area with the battery device 300, thereby further improving the stability of the clamping part 513 in abutting and clamping the battery device 300.

[0118] Please refer to Figure 4In one embodiment of this application, the clamping part 513 protrudes from the support surface 5111.

[0119] In this embodiment, the clamping part 513 is directly protruded on the support surface 5111, which helps to improve the overall compactness of the limiting part 51 and reduce the possibility of interference and collision with modules such as robotic arms.

[0120] Please refer to Figure 4 In one embodiment of this application, the clamping part 513 and the driving part 511 are an integral structure.

[0121] In this embodiment, the clamping part 513 and the driving part 511 are integrated, which can improve the overall strength of the limiting member 51.

[0122] Please refer to Figure 4 In one embodiment of this application, the limiting mechanism 50 further includes a first buffer pad 52, at least a portion of which is disposed on the support surface 5111.

[0123] The first buffer pad 52 can be used to cushion the contact with the battery device 300. The first buffer pad 52 can be made of an elastic material such as silicone or rubber. Furthermore, the first buffer pad 52 can be provided only on the support surface 5111 of the driving part 511, or it can be further provided on other surfaces of the driving part 511. Moreover, to improve the compactness of the limiting mechanism 50, a step 5112 can be provided on the support surface 5111, and the first buffer pad 52 can be installed on this step 5112. In addition, the first buffer pad 52 and the driving part 511 can be connected by adhesive or screws for easy maintenance and replacement.

[0124] In this embodiment, the buffering effect of the first buffer pad 52 can reduce the possibility of the driving part 511 damaging the surface of the battery device 300.

[0125] Please refer to Figure 4 In one embodiment of this application, the limiting mechanism 50 further includes a second buffer pad 53, at least a portion of which is disposed on the clamping surface 5131.

[0126] The second buffer pad 53 is used to cushion the contact with the battery device 300. The second buffer pad 53 can be made of an elastic material such as silicone or rubber. Furthermore, the second buffer pad 53 can be provided only on the clamping surface 5131 of the clamping part 513, or it can be further provided on other surfaces of the clamping part 513. In addition, the second buffer pad 53 and the clamping part 513 can be connected by adhesive or screws for easy maintenance and replacement.

[0127] In this embodiment, the buffering effect of the second buffer pad 53 can reduce the possibility of the clamping part 513 damaging the surface of the battery device 300.

[0128] Please refer to Figure 4 In one embodiment of this application, the limiting mechanism 50 further includes an elastic element 54, which is disposed between the driving part 511 and the tray body 10. The elastic element 54 is configured to drive the driving part 511 to rotate and reset when the driving part 511 and the battery device 300 are separated.

[0129] The elastic element 54 can be compressed and deformed when the driving part 511 is abutted and driven by the battery device 300. After the battery device 300 is removed from the tray 100, this deformation force can drive the driving part 511 to move and return to its original position. The elastic element 54 can be a spring or a sheet spring; this application does not limit the type of elastic element 54. Furthermore, when the driving part 511 is directly rotatably mounted on the tray body 10, the elastic element 54 can be disposed between the driving part 511 and the tray body 10. When the driving part 511 is rotatably mounted on the mounting member 55, the elastic element 54 can be disposed between the driving part 511 and the mounting member 55, or between the driving part 511 and the tray body 10.

[0130] In this embodiment, the automatic reset of the drive unit 511 can be achieved by setting the elastic element 54 so that the pallet 100 can be used for the next feeding.

[0131] Please refer to the reference. Figure 2 and Figure 4 In one embodiment of this application, the limiting mechanism 50 further includes a mounting member 55, which is disposed on the tray body 10. The driving part 511 is rotatably disposed on the mounting member 55, and the elastic member 54 is disposed between the driving part 511 and the mounting member 55.

[0132] The mounting member 55 can be used to provide a mounting position for mounting the driving part 511 and the elastic member 54. The mounting member 55 can be a column structure, a base structure, or a block structure, etc. This application does not limit the structural type and shape of the mounting member 55. Furthermore, the mounting member 55 can be movably mounted on the pallet body 10 as described below, or it can be fixedly mounted to the pallet body 10.

[0133] In this embodiment, a mounting member 55 is further provided. The structure of the mounting member 55 is simpler than that of the tray body 10, and its volume is relatively small, which helps to improve the convenience of installing and arranging the driving part 511 and the elastic member 54.

[0134] Please refer to the reference. Figure 2 and Figure 4 In one embodiment of this application, the driving part 511 is provided with a back face 5113, which is disposed away from the support surface 5111; the mounting member 55 is located on the side of the driving part 511 facing the back face 5113, and the elastic member 54 is disposed between the back face 5113 and the mounting member 55.

[0135] In this embodiment, the mounting member 55 is disposed on the side of the driving part 511 facing away from the opposite side 5113, which can reduce the overall volume of the limiting mechanism 50 and further improve the compactness of the structure. At the same time, the driving part 511 and the mounting member 55 are distributed in this way, and the elastic member 54 can be arranged between them more conveniently, and the arranged elastic member 54 can also apply a strong elastic force to the driving part 511.

[0136] Please refer to Figure 4 In one embodiment of this application, the mounting member 55 is provided with a first receiving groove 551 on the side facing away from the opposite side 5113, and the end of the elastic member 54 away from the opposite side 5113 is received in the first receiving groove 551.

[0137] In this embodiment, one end of the elastic member 54 is housed in the first receiving groove 551, which can limit the elastic member 54 so that the elastic member 54 can be stably installed between the driving part 511 and the mounting part 55. Moreover, the structure of the first receiving groove 551 is relatively simple, which helps to improve the convenience of limiting the installation between the elastic member 54 and the mounting part 55.

[0138] Please refer to Figure 4 In one embodiment of this application, a second receiving groove 5114 is provided on the opposite side 5113, and one end of the elastic member 54 near the opposite side 5113 is received in the second receiving groove 5114.

[0139] In this embodiment, placing the other end of the elastic member 54 within the second receiving groove 5114 can also limit the elastic member 54, allowing it to be stably installed between the driving part 511 and the mounting part 55. Furthermore, the structure of the second receiving groove 5114 is relatively simple, which further improves the convenience of limiting the installation between the elastic member 54 and the driving part 511.

[0140] Please refer to Figure 4 In one embodiment of this application, the elastic element 54 is a spring.

[0141] In this embodiment, the elastic element 54 is set as a spring, which has the advantage of good elasticity and can improve the reset effect of the driving part 511. At the same time, the spring also has the advantage of compact structure, which also helps to improve the convenience of its installation and arrangement.

[0142] Please refer to the reference. Figure 1 , Figure 2 as well as Figure 4 In one embodiment of this application, the mounting member 55 is disposed on the tray body 10, and the driving part 511 is rotatably connected to the mounting member 55.

[0143] In this embodiment, the driving part 511 is indirectly mounted on the pallet body 10 by setting the mounting part 55. The structure of the mounting part 55 is simpler and smaller than that of the pallet body 10, which improves the convenience of installing and arranging the driving part 511. The mounting part 55 can be set on the side of the driving part 511 facing away from the opposite side 5113 as described above, or it can be directly set on the side of the driving part 511 away from the stop member 30.

[0144] Please refer to the reference. Figure 2 and Figure 4 In one embodiment of this application, the mounting member 55 is provided with a mounting groove 553. The mounting groove 553 extends along the arrangement direction of the stop member 30 and the clamping part 513 and passes through the opposite sides of the mounting member 55, so that the driving part 511 is rotated and installed in the mounting groove 553.

[0145] The mounting groove 553 can be set upwards and extends along a second direction, penetrating the side of the mounting member 55 near the stop member 30 and the side away from the stop member 30. At this time, the driving part 511 can rotate the two groove walls of the mounting groove 553 that are mounted on each other in a third direction and facing upwards.

[0146] In this embodiment, the driving part 511 is rotatably installed in the mounting groove 553. The rotation of the driving part 511 can be limited by the two opposite groove walls of the mounting groove 553, which helps to improve the stability of the rotation of the limiting part 51 so as to accurately contact the battery device 300.

[0147] Please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, the mounting member 55 is movably disposed on the tray body 10 along the arrangement direction of the stop member 30 and the clamping part 513, and can be fixed relative to the tray body 10, and the driving part 511 is rotated and mounted on the mounting member 55.

[0148] The mounting component 55 can slide along the second direction and can be fixed after sliding to any position to maintain its position after being moved into place. Alternatively, the mounting component 55 can be fixed after sliding to a preset position. Furthermore, the mounting component 55 can be moved and adjusted via the driving component 56 described below. Alternatively, a groove can be provided on the tray 100, and the mounting component 55 can be slidably mounted within the groove, in which case the mounting component 55 can be directly driven for movement and adjustment.

[0149] In this embodiment, the mounting member 55 is made movable, so that the position of the limiting member 51 mounted on the mounting member 55 can be moved and adjusted, so that the tray 100 can be adapted to battery devices 300 of different types and sizes for use.

[0150] Please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, the limiting mechanism 50 further includes a driving member 56, which is disposed on the tray body 10 and configured to drive the mounting member 55 to move.

[0151] The drive component 56 can be used to drive the installation component 55 to move and adjust. The drive component 56 can be, as described below, a lead screw 561, or a cylinder. This application does not limit the type of drive component 56.

[0152] In this embodiment, by providing a driving component 56, the mounting component 55 can be moved and adjusted without disassembling it, thereby improving the convenience of adjusting the position of the mounting component 55.

[0153] Please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, the drive member 56 includes a lead screw 561, which is rotatably disposed on the tray body 10 and extends along the moving direction of the mounting member 55; the mounting member 55 is sleeved on the lead screw 561 and threadedly connected to the lead screw 561, and the lead screw 561 is configured to drive the mounting member 55 to move when rotated.

[0154] In this embodiment, the driving component 56 includes a lead screw 561, allowing the mounting component 55 to be continuously adjusted by rotating the lead screw 561. This enriches the position adjustment of the mounting component 55 and further improves the applicability of the tray 100 to battery devices 300 of different types and sizes. Furthermore, the lead screw 561 has a self-locking function, which helps improve the stability of the mounting component 55 and the limiting component 51 after they have been adjusted to their positions. The rotation of the lead screw 561 can be manually driven, or the driving component 56 can also include a motor, which is located on the tray body 10 and connected to the lead screw 561. In this case, the motor can automatically drive the lead screw 561, further improving work efficiency.

[0155] Please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, the limiting mechanism 50 further includes a locking ring 57, which is sleeved on the lead screw 561 and threadedly connected to the lead screw 561. The locking ring 57 is located on the side of the mounting member 55 away from the stop member 30.

[0156] In this embodiment, a locking ring 57 is further provided on the side of the mounting member 55 away from the stop member 30, so that after the mounting member 55 is adjusted to the position, in addition to being limited by the self-locking function of the lead screw 561, it can also be further limited by the stop member 30, so as to further improve the stability of the mounting member 55 and the limiting member 51 after the movement is adjusted to the position.

[0157] Please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, the limiting mechanism 50 further includes a fixing member 58, which is disposed on the tray body 10, and the lead screw 561 is rotatably mounted on the fixing member 58.

[0158] The fixing member 58 provides a mounting position for the lead screw 561. The fixing member 58 can be a base structure, a column structure, or a plate structure, etc., and this application does not limit the structural type and shape of the fixing member 58. Furthermore, to improve installation stability, there can be two fixing members 58, so that the opposite ends of the lead screw 561 can be respectively mounted on two fixing members 58.

[0159] In this embodiment, the structure of the fastener 58 is simpler and its volume is relatively smaller than that of the tray body 10, which helps to improve the convenience of installing and arranging the lead screw 561.

[0160] Please refer to the reference. Figure 2 , Figure 4 as well as Figure 5 In one embodiment of this application, the fixing member 58 is provided with a limiting hole 5821 and a dividing groove 5823. The lead screw 561 passes through the limiting hole 5821, and the dividing groove 5823 connects the inner side and the outer side of the limiting hole 5821 so that the fixing member 58 can deform to clamp or release the lead screw 561. The limiting mechanism 50 also includes a first locking screw 59, which connects the two parts of the fixing member 58 separated by the dividing groove 5823.

[0161] The limiting hole 5821 can be an unclosed hole, and the dividing groove 5823 can be correspondingly set at the unclosed position of the limiting hole 5821. At this time, the dividing groove 5823 can form a deformation space, allowing the two parts of the fixing member 58 separated by the dividing groove 5823 to move closer and further apart. The first locking screw 59 can be used to connect the two parts of the fixing member 58 separated by the dividing groove 5823, and during the tightening process, it can drive the two parts of the fixing member 58 separated by the dividing groove 5823 to move closer to each other and clamp the limiting screw 561; during the loosening process, the two parts of the fixing member 58 separated by the dividing groove 5823 can return to their original position and release the screw 561.

[0162] In this embodiment, a limiting hole 5821 and a partition groove 5823 are provided on the fixing member 58, and a first locking screw 59 is provided in conjunction with it, so that after the installation member 55 is adjusted to move by rotating the lead screw 561, the lead screw 561 can be locked and limited by the first locking screw 59, so as to reduce the impact of the rotation of the lead screw 561 on the stability of the installation member 55 after it is adjusted to the position.

[0163] Please refer to the reference. Figure 2 , Figure 4 as well as Figure 5 In one embodiment of this application, the fastener 58 includes a first part 581, a second part 582, and a third part 583. The first part 581 is connected to the tray body 10 and has a rotating hole 5811 through which the lead screw 561 passes. The second part 582 and the first part 581 are arranged along the extension direction of the lead screw 561 and are separate from the first part 581. The second part 582 has a limiting hole 5821 and a partition groove 5823, and the limiting hole 5821 and the rotating hole 5811 are arranged opposite to each other. The third part 583 connects the first part 581 and the second part 582.

[0164] In this embodiment, the first part 581 is connected to the tray body 10 to realize the installation of the fastener 58 on the tray body 10; at the same time, the second part 582 is used to clamp and limit the lead screw 561, so that corresponding structures can be set on different parts of the fastener 58 to achieve different functions, reducing the possibility of interference between the connection structure between the fastener 58 and the tray body 10 and the first locking screw 59, and improving the convenience of their respective arrangements.

[0165] Please refer to Figure 5 In one embodiment of this application, in order to improve the convenience of installing the fastener 58 on the tray body 10, the limiting mechanism 50 may further include a second locking screw 60, which can be used to connect the first part 581 and the tray body 10.

[0166] Please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, the tray body 10 is provided with scale markings 11 along the moving direction of the mounting member 55.

[0167] In this embodiment, a scale mark 11 is provided on the tray body 10 to indicate the moving position of the mounting component 55, thereby improving the accuracy of adjusting the position of the mounting component 55. The scale mark 11 can be a numerical mark or a graphic mark.

[0168] Please refer to Figure 2In one embodiment of this application, the mounting member 55 is provided with a scale indicator 555, which is configured to point and cooperate with the scale mark 11.

[0169] In this embodiment, the scale indicator 555 can provide more precise indication of the scale markings 11 on the tray body 10, thereby further improving the accuracy of positional adjustment of the mounting component 55. The scale indicator 555 can be a triangular marking structure, an arrow marking structure, or a pointer marking structure; this application does not limit the structural type of the scale indicator 555.
