Description

Technical Field

[0001] This utility model relates to the field of flipping equipment technology, and in particular to a flipping tooling. Background Technology

[0002] A flipping fixture is used to flip a component to meet its usage requirements. Taking the flipping fixture used for battery pack disassembly as an example, flipping the battery pack with the fixture allows either the upper or lower casing to face upwards, facilitating the removal of the upper and lower casings separately and the removal of the batteries from the battery pack.

[0003] Existing flipping fixtures typically use two clamping mechanisms to hold both ends of the battery pack, and then drive the clamping mechanisms to flip the battery pack at a preset angle. However, this type of flipping fixture requires adjusting the coaxiality and synchronization accuracy of the rotation centers of the clamping mechanisms at both ends, which is difficult to adjust and has low accuracy. This can easily lead to poor flipping stability and low flipping accuracy of the part to be flipped. Utility Model Content

[0004] In view of this, the present invention aims to provide a flipping fixture to improve the flipping effect of the workpiece.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A flipping fixture includes a base, and a rotating part and a first driving part disposed on the base;

[0007] The rotating part includes a mounting frame, and a support unit and a limiting unit disposed on the mounting frame. The support unit includes a plurality of support components arranged at intervals along a first direction, and two adjacent support components define a receiving cavity for accommodating the part to be flipped.

[0008] The limiting unit is used to limit the part to be flipped to a preset position in the receiving cavity. The first driving part is connected to the rotating part in a transmission, and the first driving part can drive the rotating part to rotate and flip the part to be flipped to a preset angle after being limited.

[0009] Furthermore, the flipping fixture also includes a tray assembly disposed within the receiving cavity; the supporting unit supports the part to be flipped through the tray assembly, and the tray assembly can be moved out of the receiving cavity along the second direction.

[0010] Furthermore, the pallet assembly includes a plurality of pallets spaced apart along the first direction, two adjacent pallets being detachably connected and forming a support space for supporting the item to be flipped; an adjustment block is detachably provided on the support surface of one of the pallets, the adjustment block being protruding relative to the support surface and used to support the item to be flipped.

[0011] Furthermore, the tray is provided with a support block forming the support surface, the support block is provided with a through hole and a locking hole, and the adjustment block is provided with a locking block; the locking block can enter the through hole and enter the locking hole through the through hole, and is locked on the support surface.

[0012] Furthermore, the supporting blocks are a plurality of blocks spaced apart on the tray along the second direction, and at least one of the supporting blocks is adjustable in position along the second direction.

[0013] Furthermore, the limiting unit includes a first limiting component that limits the part to be flipped in the first direction, a second limiting component that limits the part to be flipped in the second direction, and a third limiting component that limits the part to be flipped in a third direction.

[0014] Furthermore, the tray is provided with a positioning mechanism and a clamping mechanism. The positioning mechanism is used to position the part to be flipped on the support surface, and the clamping mechanism is used to clamp the part to be flipped after positioning.

[0015] Furthermore, the mounting frame includes two annular frames arranged opposite to each other, and a connecting beam disposed between the two annular frames; the base is provided with support wheels supporting the radial sides of the annular frames, and limiting wheels abutting against the inner side of the annular frames.

[0016] Furthermore, the first driving unit includes a driving motor mounted on the base; at least one of the annular frames is provided with a chain arranged circumferentially thereon, and the drive shaft of the driving motor is provided with a sprocket that is connected to the chain drive.

[0017] Furthermore, the support assembly includes a plurality of rollers spaced apart on the mounting frame; the mounting frame is provided with a second drive unit for driving the plurality of rollers to rotate synchronously.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] The flipping fixture of this utility model defines a receiving cavity for the part to be flipped by two adjacent supporting components, which helps to improve the supporting effect of the part to be flipped. The limiting unit limits the part to be flipped to a preset position in the receiving cavity, which helps to improve the stability of the part to be flipped during the flipping process. Furthermore, the first driving part drives the rotating part to rotate and flips the part to be flipped to a preset angle, which helps to meet the flipping requirements of the part to be flipped and has high flipping accuracy. Compared with the traditional flipping fixture that uses two clamping mechanisms, it also helps to reduce the debugging difficulty, thereby helping to speed up the production cycle.

[0020] Furthermore, supporting the workpiece to be flipped using the pallet assembly not only protects the workpiece but also facilitates its entry and exit from the receiving cavity and its transfer, thereby further improving the usability of the flipping fixture. The two pallets are detachably connected, facilitating the placement and removal of the workpiece within the pallet assembly and providing good operational convenience. The protruding adjustment blocks relative to the support surface allow for selection of whether to include them based on the structural characteristics of the workpiece, thus improving the support effect and operational flexibility. The locking blocks can enter through the through-hole and then into the locking hole, locking onto the support surface, improving the ease of removal of the adjustment blocks from the pallet. Multiple support blocks spaced apart along the second direction further enhance the support effect and allow for adjustment of their position in the second direction, enabling the determination of the support block's position according to the specifications of the workpiece, thereby further improving the operational flexibility of the support blocks.

[0021] Furthermore, by using a first limiting component to limit the component to be flipped in a first direction, a second limiting component to limit the component to be flipped in a second direction, and a third limiting component to limit the component in a third direction, the limiting effect of the component to be flipped within the receiving cavity is further improved, thereby enhancing the flipping accuracy of the component to be flipped. The positioning mechanism positions the component to be flipped on the supporting surface, and the clamping mechanism clamps the positioned component to be flipped, further improving the positioning effect and stability of the component to be flipped on the pallet.

[0022] Furthermore, the two annular frames and connecting beams in the mounting frame make the overall structure of the mounting frame more robust, better able to support the support unit, limiting unit, and other components, providing a stable support foundation for the placement, limiting, and flipping of the part to be flipped. The support wheels and limiting wheels also improve the accuracy and reliability of the flipping fixture during operation. The transmission between the chain and sprocket has high stability, ensuring the stability of the mounting frame's rotation and allowing the flipping angle of the part to be flipped to reach the preset requirements with greater precision, thus reducing flipping errors caused by transmission instability. The synchronous rotation of multiple rollers helps ensure the uniformity of force on the part to be flipped within the receiving cavity, avoiding uneven force on the part due to some rollers being stationary and others rotating, which could lead to instability such as tilting or offset. This enhances the stability and reliability of the support assembly in supporting and assisting the movement of the part to be flipped. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0057] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0058] This embodiment relates to a flipping fixture. In terms of overall structure, the flipping fixture includes a base 1, a rotating part and a first driving part 5 disposed on the base 1.

[0059] The rotating part includes a mounting frame 2, and a support unit and a limiting unit disposed on the mounting frame 2. The support unit includes a plurality of support components 3 arranged at intervals along a first direction, and two adjacent support components 3 define a receiving cavity 200 for accommodating the part to be flipped. The limiting unit is used to limit the part to be flipped to a preset position in the receiving cavity 200. The first driving part 5 is connected to the rotating part in a transmission manner, and the first driving part 5 can drive the rotating part to rotate and flip the part to be flipped to a preset angle after being limited.

[0060] The flipping fixture described in this embodiment defines a receiving cavity 200 for accommodating the part to be flipped by two adjacent supporting components 3, which improves the supporting effect on the part to be flipped. A limiting unit limits the part to be flipped to a preset position within the receiving cavity 200, improving the stability of the part during the flipping process. Furthermore, the first driving unit 5 drives the rotating unit to rotate, flipping the part to be flipped to a preset angle, thus meeting the flipping requirements and achieving high flipping accuracy. In addition, compared to traditional flipping fixtures using two clamping mechanisms, this design reduces debugging difficulty, thereby accelerating the production cycle.

[0061] Based on the above overview, an exemplary structure of the flipping fixture described in this embodiment is as follows: Figures 1 to 6 As shown in the diagram. To facilitate the explanation of the flipping fixture, a battery pack is used as an example. The preset angle can be 180°. After the battery pack is flipped by the flipping fixture, either the upper or lower housing can be facing upwards, which facilitates the disassembly of the upper or lower housing and other components.

[0062] In this embodiment, the base 1 serves as the mounting foundation for the entire flipping fixture. It can be frame-shaped and fixed to the ground or other mounting base by multiple fasteners. The base 1 is generally elongated, having both length and width directions. The mounting frame 2 is located on top of the base 1 and extends along the length of the base 1. As a preferred embodiment, the mounting frame 2 in this embodiment includes two oppositely arranged annular frames 201 and a connecting beam 202 located between the two annular frames 201. The base 1 is provided with support wheels 101 supporting the radial sides of the annular frames 201 and limiting wheels 102 abutting against the inner side of the annular frames 201.

[0063] Here, the connecting beam 202 is located between the two annular frames 201, which helps to enhance the overall structural strength of the mounting frame 2, enabling the mounting frame 2 to stably support components such as the support unit and the limiting unit. It also ensures that the mounting frame 2 will not easily deform due to stress when the battery pack is placed, limited, or flipped, thus ensuring the stability and reliability of the operation.

[0064] Specifically, such as Figure 6 As shown, the annular frame 201 is disposed opposite to both ends of the base 1, and the bottom of the mounting frame 2 is rotatably disposed on the base 1, specifically rotating about the axis of the annular frame 201. The connecting beam 202 includes a plurality of first beams 2021 arranged in a crisscross pattern within each annular frame 201, and a plurality of second beams 2022 arranged circumferentially around the annular frame 201 and connecting the first beams 2021 at both ends. In this embodiment, the crisscrossing arrangement of the first beams 2021 and the circumferential connection of the second beams 2022 are combined to improve the structural stability of the mounting frame 2.

[0065] like Figure 4 As shown, each end of the base 1 is provided with two support wheels 101 spaced apart along the width direction of the base 1, and two limiting wheels 102 disposed between the two support wheels 101. The outer peripheral wall of the annular frame 201 is provided with two annular protrusions 2011 spaced apart along the axial direction. The two support wheels 101 abut against the outer peripheral wall of the annular protrusions 2011 to support the annular frame 201, while the two limiting wheels 102 abut against the inner peripheral wall of the annular frame 201.

[0066] The annular frame 201 is specifically mounted on the base 1 in a space defined by the support wheels 101 and the limiting wheels 102 at each end. The support wheels 101 can restrict the outward movement of the annular frame 201, and the limiting wheels 102 can restrict the inward movement of the annular frame 201, thereby helping to ensure the stability of the annular frame 201 during rotation.

[0067] In practice, the diameter of the support wheel 101 is larger than that of the limiting wheel 102 to ensure its supporting effect on the annular frame 201. Of course, the specifications, position, and number of the support wheel 101 and the limiting wheel 102 can be adjusted according to usage requirements. When the mounting frame 2 rotates relative to the base 1, the support wheel 101 and the limiting wheel 102 also rotate synchronously with the annular frame 201 due to friction, thereby reducing the friction between the support wheel 101, the limiting wheel 102, and the annular frame 201.

[0068] In a preferred embodiment, the first drive unit 5 includes a drive motor mounted on the base 1, and at least one of its annular frames 201 is provided with a chain arranged circumferentially thereon. The drive shaft of the drive motor is provided with a sprocket connected to the chain drive. This chain and sprocket transmission method offers high stability and accuracy, ensuring the stability of the mounting frame 2's rotation during power transmission. This allows the battery pack's flipping angle to meet preset requirements, reducing flipping errors caused by transmission instability and improving the working accuracy of the flipping fixture. To distinguish it from the chain and sprocket described below, the chain mounted on the annular frame 201 is referred to as the first chain 203, and the sprocket connected to the first chain 203 is referred to as the first sprocket 106.

[0069] In terms of specific structure, such as Figure 4 As shown, each annular frame 201 is provided with a first chain 203. The first chain 203 is respectively disposed on the outer peripheral wall of the corresponding annular frame 201 and located between two annular protrusions 2011. The two ends of the first chain 203 are respectively fixed to the annular frame 201 by connecting blocks 409. Two first fixing seats 103 are respectively provided on the outer side of both ends of the base 1 at intervals. Each first sprocket 106 is rotatably disposed between the two first fixing seats 103. A drive shaft 501 is provided between the two first sprockets 106 to connect them together.

[0070] To improve the rotational stability of the drive shaft 501 and the first sprocket 106, a support seat 104 is provided in the middle of the base 1 for the drive shaft 501 to pass through. To enhance the protection of the sprocket, a protective cover 105 is provided on the base 1 to cover the first sprocket 106. In this embodiment, only one drive motor drives the entire mounting frame 2 to rotate, which facilitates implementation and reduces production costs. Of course, the number of drive motors can be increased adaptively according to usage requirements.

[0071] To transmit power from the drive motor to the transmission shaft 501, in this embodiment, a first gear is provided at the power output end of the drive motor, a second gear corresponding to the first gear is provided on the transmission shaft 501, and a second chain is provided between the first gear and the second gear. After the drive motor starts, the first gear rotates accordingly, and can drive the transmission shaft 501 to rotate through the second chain and the second gear, and drive the first chain 203 and the mounting bracket 2 to rotate through the first sprocket 106, thereby causing the battery pack inside the mounting bracket 2 to flip.

[0072] In this embodiment, the first direction specifically refers to the radial direction of the annular frame 201. As a preferred embodiment, the supporting assembly 3 includes a plurality of rollers 301 spaced apart on the mounting frame 2, and the mounting frame 2 is provided with a second drive unit 10 for driving the plurality of rollers 301 to rotate synchronously. Here, the spaced-apart rollers 301 facilitate the formation of the aforementioned receiving cavity 200 and facilitate the entry and exit of the part to be flipped from the receiving cavity 200. Furthermore, the rolling contact between the rollers 301 and the part to be flipped helps reduce the frictional force generated between the part to be flipped and the supporting assembly 3 during placement, movement, and subsequent flipping operations.

[0073] This embodiment uses a scheme where two support components 3 are set in the support unit as an example for explanation. Combined with... Figure 3 and Figure 4 As shown, in the lower support assembly 3, the rollers 301 are arranged in two rows side by side along the width direction of the base 1, and each row of rollers 301 consists of multiple rollers spaced apart along the axial direction of the mounting frame 2. In the upper support assembly 3, the rollers are arranged in one row. This arrangement helps to further improve the support effect of the support unit on the components to be flipped, and makes the space of the receiving cavity 200 larger, thus facilitating the flipping requirements of battery packs of different specifications and providing high flexibility in use.

[0074] In this embodiment, the principle by which the second drive unit 10 drives the roller 301 to rotate is the same as the principle of roller 301 rotation in the prior art roller 301 conveying mechanism. For example, each roller 301 has a second sprocket at both ends, and a third chain is provided outside each pair of adjacent second sprockets at the same end. The two third chains at the ends of each roller 301 are spaced apart along the axial direction of the roller 301. The second drive unit 10 also uses a drive motor, and the power output end of the drive motor is connected to the input gear at the end of one of the rollers 301. In this way, the second drive unit 10 drives the corresponding roller 301 to rotate through the input gear, and drives multiple rollers 301 in the same row to rotate synchronously through multiple third chains.

[0075] To facilitate the synchronous rotation of the two rows of rollers 301, a transmission rod 1001 extending along the width of the base 1 is provided on the base 1. Each end of the transmission rod 1001 has a third gear, and a fourth gear can be provided at the end of the corresponding roller 301 corresponding to the third gear. The third and fourth gears are connected by a fourth chain. This arrangement allows the multiple rollers 301 in the other row to rotate synchronously through the transmission of the transmission rod 1001, the third gear, the fourth gear, and the fourth chain.

[0076] In this embodiment, the part to be flipped can be fed into the receiving cavity 200 by driving multiple rollers 301 in the two supporting components 3 to rotate synchronously, and the part to be flipped can be moved out of the receiving cavity 200 by changing the rotation direction of the rollers 301. Of course, each supporting component 3 in this embodiment can also be provided with a row of rollers 301, as long as the usage requirements are met.

[0077] In a preferred embodiment, the flipping fixture described in this example further includes a tray assembly 4 disposed within the receiving cavity 200. The supporting unit supports the component to be flipped via the tray assembly 4, and the tray assembly 4 can be moved out of the receiving cavity 200 along a second direction. Here, supporting the component to be flipped via the tray assembly 4 not only facilitates the protection of the battery pack but also facilitates the component to be flipped entering and exiting the receiving cavity 200, thereby further improving the ease of use of the flipping fixture.

[0078] In this embodiment, the second direction specifically refers to the axial direction of the annular frame 201. In terms of specific structure, as... Figure 1 and Figure 7 As shown, the tray assembly 4 includes multiple trays spaced apart along a first direction. Adjacent trays are detachably connected and form a support space for supporting the component to be flipped. An adjustment block 403 is detachably provided on the support surface 400 of one tray. The adjustment block 403 protrudes relative to the support surface 400 and is used to support the component to be flipped. Here, the tray assembly 4 is detachably connected by two oppositely arranged trays, which not only facilitates the placement and removal of the battery pack in the tray assembly 4, but also helps reduce the maintenance cost and difficulty of the tray assembly 4, thereby extending its service life. Furthermore, the protrusion of the adjustment block 403 relative to the support surface 400 facilitates the installation and removal of the adjustment block 403 according to the structural characteristics of the battery pack, thereby improving the support effect on the battery pack.

[0079] Furthermore, in this embodiment, the tray is provided with a support block forming a support surface 400. The support block is provided with a through hole 4051 and a locking hole 4052 that are connected to each other. The adjusting block 403 is provided with a locking block 406. The locking block 406 can enter the through hole 4051 and then enter the locking hole 4052 from the through hole 4051, and is locked onto the support surface 400. This allows the locking block 406 to enter the through hole 4051 and then enter the locking hole 4052 from the through hole 4051, and be locked onto the support surface 400, which facilitates the removal and disassembly of the adjusting block 403 on the tray.

[0080] Taking the arrangement of two trays in tray assembly 4 as an example, as a feasible implementation method, such as... Figure 7 and Figure 8 As shown, the tray is a hollow frame. To facilitate the support of the battery pack, the support block in this embodiment extends along the width of the tray. The support block not only improves the support effect of the battery pack, but also improves the structural strength of the tray.

[0081] For ease of distinction and description, Figure 7 Based on the perspective shown, the lower tray is referred to as the lower tray 401, and the upper tray is referred to as the upper tray 402. Before the battery pack is flipped, the lower tray 401 is located at the bottom of the battery pack and supports it. After the flipping fixture flips the battery pack, the upper tray 402 is located at the bottom of the battery pack and supports it. In this embodiment, the tray assembly 4 not only facilitates the entry and exit of the battery pack from the receiving cavity 200, but also supports the battery pack before and after flipping, thereby ensuring the effective flipping and transfer of the battery pack.

[0082] The support block disposed on the lower tray 401 is referred to as the lower support block 405, and the support block disposed on the upper tray 402 is also referred to as the lower support block 405. Both the lower support surface 400 on the lower support block 405 and the upper support surface 400 on the upper support block 404 face the battery pack. In this embodiment, the adjustment block 403 is specifically disposed on the lower support block 405 to facilitate the lower tray 401 in supporting the disassembled battery pack at the bottom.

[0083] Specifically, after the lower casing and liquid cooling plate of the battery pack are removed, the edge of the bottom of the battery pack is lower than the removed portion. Therefore, the lower support surface 400 on the lower support block 405 is used to support the edge of the bottom of the battery pack, while the adjustment block 403 is used to support other parts of the bottom of the battery pack. It should be noted that in this embodiment, the adjustment block 403 only needs to be installed on the lower support block 405 after the bottom of the battery pack has been disassembled. In other cases, the adjustment block 403 does not need to be installed on the lower support block 405.

[0084] The lower support block 405 has a through hole extending along its length, which facilitates both meeting the usage requirements of the support block and reducing the weight of the flipping fixture. The snap-fit ​​block 406 includes a cylindrical portion and a snap-fit ​​portion located at one end of the cylindrical portion and protruding radially outward. The free end of the cylindrical portion is used to connect with the first support block, and the connection method can be screwed, which facilitates the detachable connection between the snap-fit ​​block 406 and the first support block. In addition, when the snap-fit ​​block 406 and the adjusting block 403 are connected, the snap-fit ​​portion and the adjusting block 403 are spaced apart, forming a snap-fit ​​space.

[0085] like Figure 14 As shown, in this embodiment, the through hole 4051 is circular, and the locking hole 4052 extends along the length of the lower support block 405, with one end of the locking hole 4052 connected to the through hole 4051. (Refer to...) Figures 11 to 14 As shown, after the snap-fit ​​portion of the snap-fit ​​block 406 is inserted into the through hole 4051, it slides into the snap hole 4052. When the column portion abuts against the end of the snap hole 4052, the top wall of the lower support block 405 can be snapped into the snap-fit ​​space, so that the adjusting block 403 cannot move relative to the lower support block 405 in the thickness direction of the lower support block 405, and the adjusting block 403 is installed on the lower support block 405.

[0086] To improve the installation stability of the adjusting block 403 on the lower support block 405, this embodiment provides two snap-fit ​​blocks 406 on the adjusting block 403, and provides through holes 4051 and snap holes 4052 on the lower support block 405 that correspond one-to-one with the snap-fit ​​blocks 406. This allows an adjusting block 403 to be snapped onto the lower support block 405 by the two snap-fit ​​blocks 406. Of course, the number of snap-fit ​​blocks 406 can be increased adaptively according to usage requirements.

[0087] Furthermore, after the adjusting block 403 is snapped into place, its two ends can be connected to the lower support block 405 by bolts, which helps to further ensure the installation firmness of the adjusting block 403 on the lower support block 405. It should be noted that the adjusting block 403 can be provided on the lower support block 405 of each lower tray 401, or it can be provided on only some of the support blocks, as long as the usage requirements are met. In this embodiment, protective pads 4053 are provided on the top surface of the lower support block 405 and the bottom surface of the upper support block 404, wherein the through hole 4051 and the snap hole 4052 of the lower support block 405 pass through the protective pads 4053.

[0088] In this embodiment, multiple support blocks are spaced apart on the tray along the second direction, and the position of at least one support block in the second direction is adjustable. The cooperation of multiple support blocks helps to improve the stability of supporting the battery pack, and the adjustable position of at least one support block in the second direction allows for further adjustment of the position of the support block according to the specifications of the battery pack, thus providing good flexibility in use.

[0089] Reference Figure 8 As shown, slide rails 407 extending along their length are provided on both sides of the tray width direction. Slider blocks 408 are provided at both ends of the support blocks, slidably mounted on the corresponding slide rails 407. The support blocks are adjusted in position through the sliding engagement of the sliders 408 and the slide rails 407. To position the moved support blocks, connecting blocks 409 extending outwards are provided at the ends of each support block. A first connecting hole is provided through the connecting block 409. Corresponding to the first connecting hole, multiple second connecting holes are spaced apart along the length of the tray. Connecting components, such as bolts, can pass through the first connecting hole and the overlapping second connecting holes and connect with a nut, thereby fixing the support block to the corresponding tray.

[0090] In this embodiment, the arrangement of the connecting block 409, the first connecting hole, the second connecting hole, and the connector facilitates a detachable connection between the connecting block 409 and the tray, thereby enabling adjustment of the support block's position and providing good operational flexibility. Of course, besides using connecting holes and connectors for fixation, other easy-to-disassemble connection methods can also be used, as long as the usage requirements are met.

[0091] In a preferred embodiment, the tray is equipped with a positioning mechanism and a clamping mechanism. The positioning mechanism is used to position the component to be flipped on the supporting surface 400, and the clamping mechanism is used to clamp the component after positioning. This improves the positioning effect of the battery pack on the supporting surface 400, thereby improving the stability of the battery pack during the flipping process. Considering that the positioning mechanism and clamping mechanism are the same on both trays, the following description focuses on the lower tray 401.

[0092] like Figure 8 and Figure 9 As shown, a positioning seat 410 is provided at the end of the lower tray 401. The positioning mechanism includes a positioning part 411 that is provided on the positioning seat 410 and protrudes upward. The positioning part 411 is provided with a first positioning hole and a positioning pin 412 inserted into the first positioning hole. By inserting the positioning pin 412 into the original hole on the battery pack, it is convenient to guide the battery pack to be placed on the support surface 400 on the lower tray 401.

[0093] Furthermore, the positioning mechanism also includes first positioning blocks 413 disposed on at least a portion of the sliders 408. By abutting against the battery pack through the first positioning blocks 413 located on both sides, the battery pack can be positioned on the support surface 400 in the width direction of the lower tray 401. To guide the battery pack into the support surface 400, inclined guide surfaces can also be provided on the top of each first positioning block 413. By abutting against the battery pack through the guide surfaces, the battery pack can be guided to be positioned on the support surface 400.

[0094] The positioning structure in this embodiment also includes second positioning blocks 417 disposed at both ends of the tray, which position the battery pack in a second direction by abutting against the ends of the battery pack. The second positioning block 417 also has an inclined guide surface. In specific implementation, both the first positioning block 413 and the second positioning block 417 are made of insulating material.

[0095] Considering the different positions of the origin hole on battery packs of different specifications, the position of the positioning pin 412 is adjustable in this embodiment to further improve the versatility of the positioning mechanism. For example... Figure 9 As shown, a movable seat 414 is provided on the lower tray 401, which is movable along its width direction, and a positioning seat 410 is movably disposed on the movable seat 414 in a second direction. This arrangement allows the position of the positioning pin 412 in the length and width directions of the lower tray 401 to be adjustable, thereby enabling the positioning pin 412 to be inserted into the origin hole at different positions. This allows for the positioning of battery packs of multiple specifications, thus providing good versatility.

[0096] The specific structure still refers to Figure 9 As shown, the movable seat 414 is slidably disposed on the lower tray 401 along the width direction of the lower tray 402. To drive the movable seat 414 to move, a first adjusting bolt 415 is provided on the lower tray 401, extending along the width direction of the lower tray 402. The first adjusting bolt 415 is rotatably disposed on the lower tray 401, and its output end is screwed to the movable seat 414. By driving the first adjusting bolt 415 to rotate, the screw length between the first adjusting bolt 415 and the movable seat 414 can be changed, thereby driving the movable seat 414 to move along the width direction of the lower tray 402, thus adjusting the position of the positioning pin 412 in the width direction of the lower tray 402.

[0097] A second adjusting bolt 416 is rotatably mounted on the movable base 414, extending along the length of the lower tray 401, and the output end of the second adjusting bolt 416 is screwed to the positioning base 410. By driving the second adjusting bolt 416 to rotate, the screw length between the second adjusting bolt 416 and the positioning base 410 can be changed, thereby driving the movable base 414 to move along the length of the lower tray 401, thus adjusting the position of the positioning pin 412 in the length direction of the lower tray 401. Of course, in addition to using the adjusting bolt, other methods can be used to adjust the position of the positioning pin 412, as long as the usage requirements are met. In addition, a scheme that only makes the position adjustable in the length direction of the lower tray 401 or the width direction of the lower tray 402 is also feasible.

[0098] In addition, to prevent interference between the positioning pins 412 on the upper tray 402 and the lower tray 401 when they are engaged, the positioning pins 412 on the lower tray 401 can be made detachable. When the lower tray 401 and the upper tray 402 are engaged, the positioning pins 412 can be pulled out, at which point the positioning pins 412 on the upper tray 402 can be inserted into the first positioning hole on the lower tray 401, and the upper tray 402 is positioned on the lower tray 401.

[0099] To improve the fit between the upper tray 402 and the lower tray 401, positioning components are provided at opposite corners of both, so that the two positioning devices are aligned. Specifically, as shown in the following structure... Figure 7 and Figure 8 As shown, the positioning assembly includes a second positioning hole 418 at one corner of one tray and a positioning post 419 at the other corner. A corresponding positioning post 419 and second positioning hole 418 are provided on the other tray. The insertion and engagement of the positioning post 419 into the corresponding second positioning hole 418 facilitates the positioning of the upper tray 402 and the lower tray 401 together.

[0100] like Figure 7 and Figure 8 As shown, the clamping mechanism in this embodiment includes adjustable latches 420 disposed at both ends of each tray. Its structure offers high flexibility, adapting to clamping battery packs of different sizes, and the clamping force can be adjusted according to the specifications of the battery pack. Furthermore, compared to some complex clamping mechanisms, the adjustable latches 420 save significant installation and disassembly time, thereby improving work efficiency. Additionally, the clamping mechanism in this embodiment also serves to quickly clamp and release the battery pack.

[0101] In this embodiment, the adjustable latches 420 at both ends of each tray clamp the battery pack, thereby achieving a detachable connection between the upper tray 402 and the lower tray 401. This eliminates the need for a separate connecting structure between the two, improving the structural utilization of the adjustable latches 420 and reducing the number of parts. Alternatively, bolts can be provided between the upper tray 402 and the lower tray 401 to connect them. Bolts have a simple structure, are easy to install and disassemble, and provide a good connection effect.

[0102] In a preferred embodiment, the limiting unit includes a first limiting component that limits the component to be flipped in a first direction, a second limiting component that limits the component to be flipped in a second direction, and a third limiting component that limits the component to be flipped in a third direction. The provision of the first, second, and third limiting components helps to further improve the placement stability of the battery pack on the mounting bracket 2, thereby improving the flipping effect of the battery pack.

[0103] by Figure 1 and Figure 16 Based on the perspective shown, in this embodiment, the first limiting component is correspondingly disposed on the outer side of the upper tray 402 and has two rows spaced apart along the width direction of the tray. Each row of the first limiting component includes multiple first limiting plates 6 spaced apart along the axial direction of the mounting frame 2, and each first limiting plate 6 is located between two adjacent second rollers 301. By driving the first limiting plate 6 to move closer to the battery pack, it can abut against the top of the battery pack, thereby limiting the upward displacement of the battery pack. At this time, the first roller 301 supports the lower tray 401 and limits the downward displacement of the battery pack through the lower tray 401.

[0104] In this embodiment, the first limiting component also includes two connecting plates 601 extending along the axial direction of the mounting frame 2. The two ends of each first limiting plate 6 are connected to the upper connecting plate 601 through connecting posts 602. By driving the connecting plate 601 to move up and down, the corresponding first limiting plate 6 can be moved up and down, so that the first limiting plate 6 can abut against the top of the battery pack or release the abutment against the top of the battery pack.

[0105] Corresponding to each connecting plate 601, a third drive unit 7 is also provided on the mounting bracket 2. The third drive unit 7 is used to output linear driving force and is connected to the connecting plate 601, so that the first limiting plate 6 can be moved up and down through the connecting plate 601 by means of the third drive unit 7. By setting the third drive unit 7, the automatic effect of the first limiting component in use is further improved. In specific arrangements, the third drive unit 7 can be a cylinder or the like.

[0106] The second limiting component in this embodiment includes a limiting frame 8 disposed at one end of the mounting frame 2, such as... Figure 4 As shown, the two ends of the limiting frame 8 are specifically connected to the first beam 2021. There are two limiting frames 8 spaced apart here. Relative to the limiting frame 8, the other end of the mounting frame 2 forms the inlet / outlet for the tray assembly 4 and the battery pack entering and exiting the receiving cavity 200. As the tray assembly 4 feeds the battery pack into the receiving cavity 200, the limiting frame 8 abuts against the corresponding end of the tray assembly 4, thus limiting the tray assembly 4. At this time, the first drive unit 5 is closed, and the tray assembly 4 moves into place.

[0107] In this embodiment, the third direction is the radial direction of the annular frame 201 and is orthogonal to the first direction. The third limiting component includes a plurality of second limiting plates 9 disposed on the left and right sides of the supporting component 3, and each second limiting plate 9 can move along the third direction, so that the top of the second limiting plate 9 can abut against the side of the upper tray 402 and the bottom of the second limiting plate 9 can abut against the side of the lower tray 401, thereby restricting the tray component 4 in the receiving cavity 200 in the third direction.

[0108] like Figure 1 , Figure 17 and Figure 18 As shown, to facilitate the movement of the second limiting plate 9, a second fixing seat 107 is provided on the mounting frame 2 corresponding to each second limiting plate 9. A first lead screw 11 extending in a third direction is threaded through the second fixing seat 107 and screwed to the second fixing seat 107. One end of the first lead screw 11 is provided with a first handwheel, and the other end is rotatably connected to the outer side of the second limiting plate 9. By holding the first handwheel to drive the first lead screw 11 to rotate, the first lead screw 11 can be moved in a third direction, and the mounting plate 901 can drive the second limiting plate 9 to rotate in a third direction.

[0109] To further improve the stability of the second limiting plate 9 during movement, a plurality of first guide posts 1071 extending towards the mounting plate 901 are provided on the second fixed base 107, and the mounting plate 901 passes through the plurality of first guide posts 1071. The mounting plate 901 is provided with clearance holes for avoiding the third lead screw. A plurality of second guide posts 902 extending outward are provided on the outer side of the second limiting plate 9, and the mounting plate 901 is provided with guide holes for each second guide post 902 to pass through. During the movement of the second limiting plate 9 driven by the third lead screw, the guiding cooperation of the first guide posts 1071, the second guide posts 902 and the mounting plate 901 helps to prevent the second limiting plate 9 from rotating relative to the mounting frame 2, thereby ensuring the limiting effect of the second limiting plate 9 on the pallet assembly 4.

[0110] like Figure 18As shown in the figure, the second limiting plate 9 in this embodiment is provided with buffer pads at both the top and bottom. The buffer pads can be made of elastic material to prevent the second limiting plate 9 from hitting the tray assembly 4 and to improve the protection effect on the tray assembly 4.

[0111] To further improve the limiting effect on the flipped parts, such as Figure 1 and Figure 19 As shown, in this embodiment, the third limiting component further includes a third fixing seat 108 disposed on one side of the mounting bracket 2, and a second lead screw 12 passing through and screwed to the third fixing seat 108. The second lead screw 12 extends in a third direction, and one end of the second lead screw 12 is provided with a second handwheel, and the other end is provided with a limiting block 1201. By driving the second lead screw 12 to rotate, the limiting block 1201 can be moved in a third direction and abut against the side of the battery pack, thereby abutting and limiting the battery pack in the tray assembly 4 in the receiving cavity 200. The limiting block 1201 here is also made of an elastic material to improve the protection effect on the battery pack.

[0112] Furthermore, in this embodiment, the position of the third fixing seat 108 in the first direction is adjustable, which helps to improve the flexibility and versatility of the limiting block 1201 in use. Specifically, in terms of structure, as... Figure 19 As shown, the mounting bracket 2 has a vertical plate 1081 extending along a first direction, and a guide rail 1082 extending along the first direction is provided on the vertical plate 1081. The third fixing seat 108 is slidably mounted on the guide rail 1082. To position the moved third fixing seat 108, multiple first teeth 1083 extending along the first direction are provided on both sides of the vertical plate 1081. Side plates located outside the vertical plate 1081 are provided on both sides of the third fixing seat 108. Through holes are provided on the side plates, and locking blocks 109 are slidably disposed in the through holes along the first direction. The locking blocks 109 are provided with second teeth that engage with the first teeth 1083.

[0113] To drive the locking block to move in the first direction, a U-shaped mounting block 1084 is provided on the outer side of the side plate. An adjusting screw 1091 is threaded through the mounting block 1084 and screwed to it. One end of the adjusting screw 1091 is rotatably connected to the locking block, and the other end is provided with an operating block. By driving the adjusting screw 1091 to rotate, the locking block can be moved in the first direction, thereby locking the second tooth onto the first tooth 1083, thus fixing the third fixing seat 108 on the upright plate 1081. Alternatively, the second tooth can be separated from the first tooth 1083, allowing the third fixing seat 108 to detach from the upright plate 1081, and thus enabling movement of the third fixing seat 108. It should be noted that, in addition to using the first tooth 1083 and the second tooth for locking, other methods can also be used to lock the third fixing seat 108, as long as the usage requirements are met.

[0114] In a preferred embodiment, the mounting bracket 2 of this embodiment is provided with a guide portion for guiding the tray assembly 4 to move onto the support unit. This arrangement facilitates the entry of the tray assembly 4 into the receiving cavity 200 within the support unit. Specifically, refer to... Figure 3 As shown, relative to the limiting frame 8, a plurality of guide cylinders 204 are provided at the other end of the mounting frame 2 at the inlet and outlet of the receiving cavity 200. Each guide cylinder 204 is rotatably mounted on the first beam 2021 of the mounting frame 2. Before the pallet assembly 4 is inserted into the receiving cavity 200, it is first abutted against the top and bottom of the pallet assembly 4 by the plurality of guide cylinders 204, thereby facilitating the guidance of the pallet assembly 4 into the receiving cavity 200.

[0115] In this embodiment, when the flipping fixture is used, the battery pack is first positioned on the lower tray 401 and fixed on the lower tray 401 by the adjustable buckle 420. Then, the upper tray 402 is installed on top of the battery pack and the battery pack is fixed on the upper tray 402 by the adjustable buckle 420, thereby completing the installation of the battery pack in the tray assembly 4.

[0116] The tray assembly 4 is moved into the receiving cavity 200 to transfer the battery pack. During this process, the guide cylinder 204 abuts against the upper tray 402 and the lower tray 401, guiding the tray assembly 4 into the receiving cavity 200. As the upper and lower rollers 301 rotate, the tray assembly 4 moves toward the limiting frame 8. When the end of the tray assembly 4 abuts against the limiting frame 8, it indicates that the tray assembly 4 has moved into place. At this time, the third drive unit 7 drives the first limiting plate 6 to move and abut against the tray assembly 4 to restrict the movement of the tray assembly 4 in the first direction. Then, by rotating the first lead screw 11, the second limiting plate 9 abuts against both sides of the battery pack to restrict the movement of the tray assembly 4 in the third direction. Furthermore, by rotating the second lead screw 12, the limiting block 1201 abuts against the battery pack to further restrict the movement of the battery pack in the third direction, thereby completing the fixation of the tray assembly 4 on the mounting frame 2.

[0117] Next, the first drive unit 5 drives the mounting bracket 2 to rotate 180°, thus completing the battery pack flipping. At this time, the upper tray 402 supports the battery pack, and the lower tray 401 is located on top of the battery pack. Then, the first limiting plate 6, the second limiting plate 9, and the limiting block 1201 release the limiting positions on the tray assembly 4 and the battery pack. Then, the roller 301 is rotated in the opposite direction to send the tray assembly 4 out of the receiving cavity 200. It should be noted that the preset flipping angle of the flipping fixture can be adjusted adaptively according to the usage requirements.

[0118] The flipping fixture described in this embodiment, through the cooperation of the support component 3 and the tray component 4 in the mounting frame 2, improves the support effect on the parts to be flipped, such as battery packs, and enhances the stability of the parts to be flipped during the flipping process. Furthermore, the entire mounting frame 2 operates smoothly and has high flipping efficiency, which helps to accelerate the production cycle. In addition, after removing the mounting frame 2, each tray can support the parts to be flipped, which also helps to meet the needs of transferring and other operations of the parts to be flipped, further enhancing the flexibility of the tray component 4. At the same time, the multiple rollers 301 cooperate to form a receiving cavity 200, which also helps to support parts to be flipped of different specifications, thereby improving the versatility of the flipping fixture in use. In addition, this flipping fixture also helps to ensure the safety of the battery pack and has good practicality.

[0119] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
