Description

Technical Field

[0001] This invention relates to the field of battery manufacturing equipment technology, and in particular to a flipping device. Background Technology

[0002] During battery production, especially in cylindrical battery production, current collectors need to be welded to both ends of the cell. These two current collectors are the positive current collector and the negative current collector, respectively. After the current collector is welded to one end of the cell, the cell needs to be rotated 180° using a flipping device to facilitate the welding of the current collector to the other end.

[0003] However, traditional flipping devices consist of a linear conveyor line and various actuating mechanisms arranged sequentially along this line. The battery cell is positioned on a tray, which is conveyed along the linear conveyor line. These mechanisms typically include an ejection mechanism to push the battery cell out of the tray, a flipping mechanism to flip the ejected battery cell, and a pressing mechanism to press the flipped battery cell back into the tray. In other words, various workstations are arranged at intervals along the linear conveyor line, with each workstation corresponding to one of the aforementioned mechanisms. The battery cell passes through these workstations sequentially along the linear conveyor line, completing its corresponding actions at each workstation, ultimately achieving the flipping of the battery cell. Because there are many steps involved in flipping the battery cell, there are many workstations arranged along the linear conveyor line, resulting in traditional flipping devices having a complex structure and requiring a large amount of space. Summary of the Invention

[0004] Therefore, it is necessary to provide a flipping device that improves upon the aforementioned shortcomings, addressing the issues of complex structure and large space requirements of existing flipping devices.

[0010] A pressing component is disposed on the mounting bracket and located on the side of the flipping component opposite to the supporting component, and is movable relative to the mounting bracket along the first direction;

[0011] As the lifting assembly moves toward the carrying assembly along the first direction, it can push the component inside the carrier toward the flipping assembly to the flipped position; the flipping assembly is used to clamp and flip the component located at the flipped position; as the pressing assembly moves toward the carrying assembly along the first direction, it can push the component located at the flipped position into the carrier on the carrying assembly.

[0012] In one embodiment, the support component is movable relative to the mounting frame along the first direction;

[0013] The flipping mechanism also includes a stop assembly disposed on the mounting frame, the stop assembly being located between the carrying assembly and the flipping assembly; during the process of the lifting assembly pushing against the components inside the vehicle toward the flipping assembly, the stop assembly is capable of stopping the vehicle.

[0014] In one embodiment, the stop assembly is movable relative to the mounting bracket along the first direction and can stop at a stop position; when the stop assembly moves to the stop position, it can engage with the stop of the passing vehicle.

[0015] In one embodiment, the flipping mechanism further includes a first elastic element connected between the support component and the stop component, wherein as the support component moves away from the flipping component along the first direction, the first elastic element drives the stop component to leave the stop position.

[0016] In one embodiment, the flipping device further includes a turntable and a drive mechanism. The turntable is rotatably disposed about a rotation axis parallel to the first direction, and the mounting bracket is mounted on the turntable. The drive mechanism has a first guide channel extending around the rotation axis, and a first guide wheel that rolls with the first guide channel is mounted on the lifting assembly.

[0017] During the rotation of the mounting bracket around the rotation axis driven by the turntable, the first guide wheel, guided by the first guide channel, drives the lifting assembly to move along the first direction.

[0018] In one embodiment, the drive mechanism has a second guide channel extending around the rotation axis, and a second guide wheel that rolls into the second guide channel is mounted on the bearing assembly;

[0019] During the rotation of the mounting bracket around the rotation axis driven by the turntable, the second guide wheel, guided by the second guide channel, drives the bearing assembly to move along the first direction.

[0020] In one embodiment, the drive mechanism has a third guide channel extending around the rotation axis, and a third guide wheel that rolls with the third guide channel is mounted on the pressing assembly;

[0021] During the rotation of the mounting bracket around the rotation axis driven by the turntable, the third guide wheel, guided by the third guide channel, drives the pressing assembly to move along the first direction.

[0022] In one embodiment, the flipping assembly includes a mounting plate, a first clamping seat, and a second clamping seat;

[0023] The mounting plate is rotatably connected to the mounting bracket about a rotation axis perpendicular to the first direction; the first clamping seat and the second clamping seat are disposed opposite to each other on the mounting plate and can be controlled to move closer or further away from each other to clamp or release the element located in the flipped position.

[0024] In one embodiment, the flipping assembly further includes a gear shaft and a rack, the gear shaft being rotatably connected to the mounting bracket and fixedly connected to the mounting plate; the rack being controllably movable and connected to the mounting bracket, and meshing with a gear on the gear shaft.

[0025] In one embodiment, the flipping assembly further includes a pin movably connected to the mounting bracket along a second direction perpendicular to the first direction;

[0026] The ejector pin has a wedge-shaped end extending between the first clamping seat and the second clamping seat. The wedge-shaped end has a first wedge-shaped surface on the side facing the first clamping seat and a second wedge-shaped surface on the side facing the second clamping seat. The distance between the first wedge-shaped surface and the second wedge-shaped surface gradually increases or decreases in the second direction.

[0027] The flipping assembly further includes a second elastic element connected between the first clamp and the second clamp to provide a preload force that causes the first clamp and the second clamp to move closer to each other.

[0028] In one embodiment, the flipping assembly further includes a first roller mounted on the first clamping seat and a second roller mounted on the second clamping seat;

[0029] The first roller rolls in contact with the first wedge surface, and the second roller rolls in contact with the second wedge surface.

[0031] The first clamping seat is equipped with a first limiting roller, and the second clamping seat is equipped with a second limiting roller, and both the first limiting roller and the second limiting roller are rolled in the limiting groove.

[0032] In actual operation, the aforementioned flipping device first loads the carrier containing the component onto the carrier assembly. Then, the lifting assembly is controlled to move towards the carrier assembly along a first direction, pushing the component from the carrier onto the flipping assembly until it separates from the carrier and reaches the flipping position, where it is then clamped by the flipping assembly. Next, the lifting assembly is controlled to move away from the carrier assembly along the first direction. The flipping assembly rotates the clamped component 180°. After the component is in position, the flipping assembly releases its clamp, and simultaneously, the pressing assembly is controlled to move towards the flipping assembly along the first direction, pressing the component at the flipped position into the carrier assembly's carrier. Finally, the pressing assembly is controlled to move away from the flipping assembly along the first direction back to its initial position and unloads the carrier onto the carrier assembly to facilitate subsequent processes.

[0033] Thus, the flipping device of the present invention integrates three processes: ejecting the component from the carrier, flipping the component, and pressing the component back into the carrier, that is, completing all three processes in one station. Compared with the prior art, which completes the ejection, flipping, and pressing processes separately at three stations arranged along a straight conveyor line, the structure of the device is greatly simplified and the required space is saved.

[0043] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element B referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0046] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components B or the interaction between two components B, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0048] It should be noted that when component B is referred to as "fixed to" or "set on" another component B, it can be directly on the other component B or there may be an intermediate component B. When a component B is considered to be "connected to" another component B, it can be directly connected to the other component B or there may be an intermediate component B present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0049] Please see Figure 1 As shown, one embodiment of the present invention provides a flipping device for flipping a component B carried within a carrier A. It should be noted that the component B can be a battery cell, and in other embodiments it can be other products; this is not limited here.

[0050] Please see Figure 3 and Figure 4As shown, the flipping device includes a flipping mechanism 1, which comprises a mounting frame 10, a support assembly 20, a lifting assembly 30, a flipping assembly 40, and a pressing assembly 50. The support assembly 20 is mounted on the mounting frame 10 and is used to support the carrier A. The lifting assembly 30 is mounted on the mounting frame 10 and is controllably movable relative to the mounting frame 10 along a first direction X. The flipping assembly 40 is mounted on the mounting frame 10 and is located on opposite sides of the support assembly 20 along the first direction X, respectively, as is the lifting assembly 30. The pressing assembly 50 is mounted on the mounting frame 10 and is located on the side of the flipping assembly 40 opposite to the support assembly 20; the pressing assembly 50 is controllably movable relative to the mounting frame 10 along the first direction X. In other words, the lifting component 30, the bearing component 20, the flipping component 40, and the pressing component 50 are arranged sequentially on the mounting frame 10 along the first direction X, and the lifting component 30 can be controlled to move closer to or away from the bearing component 20 along the first direction X, and the pressing component 50 can also be controlled to move closer to or away from the flipping component 40 along the first direction X.

[0051] During the movement of the lifting assembly 30 toward the support assembly 20 along the first direction X, it can push the component B inside the carrier A toward the flipping assembly 40 to the flipping position a. The flipping assembly 40 is used to clamp and flip the component B that has reached the flipping position a. During the movement of the pressing assembly 50 toward the support assembly 20 along the first direction X, it can push the component B at the flipping position a into the carrier A on the support assembly 20.

[0052] In actual operation, the aforementioned flipping device first loads carrier A, carrying component B, onto carrier assembly 20. Then, the lifting assembly 30 is controlled to move along the first direction X toward carrier assembly 20, causing it to push component B from carrier A onto flipping assembly 40 until it separates from carrier A and reaches flipping position a, where it is then clamped by flipping assembly 40. Next, the lifting assembly 30 is controlled to move away from carrier assembly 20 along the first direction X. Flipping assembly 40 then flips the clamped component B 180°. Once component B is in position, flipping assembly 40 releases its clamp on component B, and simultaneously, pressing assembly 50 is controlled to move along the first direction X toward flipping assembly 40, causing it to press component B at flipping position a into carrier A within carrier assembly 20. Finally, pressing assembly 50 is controlled to move along the first direction X away from flipping assembly 40 back to its initial position, and carrier A on carrier assembly 20 is unloaded to facilitate subsequent processes.

[0053] Thus, the flipping device of the present invention integrates three processes: ejecting component B from carrier A, flipping component B, and pressing component B back into carrier A, that is, completing all three processes in one station. Compared with the prior art, which completes the ejection, flipping, and pressing processes separately at three stations arranged along a straight conveyor line, the structure of the device is greatly simplified and the required space is saved.

[0054] In embodiments of the present invention, the carrying component 20 is controllably movable relative to the mounting frame 10 along a first direction X. The flipping mechanism 1 further includes a stop component 60 disposed on the mounting frame 10, the stop component 60 being located between the carrying component 20 and the flipping component 40, so that the stop component 60 can stop the carrier A during the process of the lifting component 30 pushing the element B inside the carrier A toward the flipping component 40.

[0055] Thus, when it is necessary to push component B out of carrier A, firstly, the lifting assembly 30 is controlled to move along the first direction X toward the bearing assembly 20 (i.e., Figure 3 and Figure 4 (as shown in the diagram, moving upwards), while simultaneously controlling the support component 20 to move along the first direction X toward the flipping component 40 (i.e., moving upwards). Figure 3 and Figure 4 (As shown in the diagram, moving upwards). When the carrying assembly 20 reaches the stop assembly 60, the carrier A on the carrying assembly 20 contacts the stop assembly 60 and moves the stop assembly 60 together toward the tilting assembly 40 until the stop assembly 60 reaches the stop position. The stop assembly 60 reaches the stop position and stops moving, thereby stopping the carrier A, causing the carrying assembly 20 and the carrier A to stop moving as well. As the lifting assembly 30 continues to move toward the carrying assembly 20 along the first direction X (i.e., upward movement), Figure 3 and Figure 4 The upward movement shown in the figure causes the lifting assembly 30 to push the element B inside the carrier A toward the flipping assembly 40 (at this time, due to the stop assembly 60, the carrier assembly 20 and the carrier A on the carrier assembly 20 stop moving) until the element B reaches the flipping position a (see Figure 5) and is clamped and fixed by the flipping assembly 40.

[0056] It should be noted that component B, even after reaching the flipping position a, can still remain partially inside the carrier A to prevent it from falling or shifting position before being completely separated from the carrier A and clamped and secured by the flipping assembly 40. After component B is clamped and secured by the flipping assembly 40, the lifting assembly 30 and the carrying assembly 20 are controlled to return along the first direction X (i.e., Figure 3 and Figure 4 (as shown in the downward movement), so that the element B, which is held and fixed by the flipping component 40, is completely separated from the carrier A on the carrying component 20.

[0057] Specifically, in this embodiment, the stop assembly 60 is movable relative to the mounting bracket 10 along the first direction X and can stop at the stop position during its movement toward the flipping assembly 40. When the stop assembly 60 moves to the stop position, it can cooperate with the stop of the carrier A on the passing support assembly 20, thereby preventing the support assembly 20 and the carrier A from continuing to move toward the flipping assembly 40, so that the element B in the carrier A can be pushed out to the flipping position a by the lifting assembly 30. After the element B in the carrier A is pushed out to the flipping position a and clamped and fixed by the flipping assembly 40, the lifting assembly 30, the support assembly 20 and the stop assembly 60 are controlled to move away from the flipping assembly 40 along the first direction X. On the one hand, this completely separates the element B from the carrier A on the support assembly 20, and on the other hand, it avoids the flipping action of the flipping assembly 40, thereby preventing the lifting assembly 30, the support assembly 20 and the stop assembly 60 from interfering with the flipping action of the flipping assembly 40 in flipping the element B.

[0058] Furthermore, the flipping mechanism 1 also includes a first elastic element 70 connected between the supporting component 20 and the stop component 60. As the supporting component 20 moves away from the flipping component 40 along the first direction X, the supporting component 20, through the first elastic element 70, drives the stop component 60 away from the stop position, thereby preventing the flipping action of the flipping component 40 from being obstructed. Optionally, the first elastic element 70 can be a spring.

[0059] In a specific embodiment, the lifting assembly 30 includes a lifting seat 31 and a push rod 32. The lifting seat 31 is controllably movably connected to the mounting frame 10 along a first direction X. One end of the push rod 32 is fixedly connected to the lifting seat 31, and the other end of the push rod 32 extends toward the bearing assembly 20 to push against the component B in the carrier A on the bearing assembly 20.

[0060] Furthermore, the mounting frame 10 is provided with a first slide rail 11 extending longitudinally along the first direction X, and the lifting seat 31 is provided with a first slider 34 that slides and engages with the first slide rail 11, thereby guiding the movement of the lifting seat 31 relative to the mounting frame 10 by the movement of the first slider 34 along the first slide rail 11.

[0061] In a specific embodiment, the support assembly 20 includes a support base 21 for supporting the carrier A, which is controllably movably connected to the mounting frame 10 along a first direction X. The support base 21 has a through hole (not shown) through which a top rod 32 passes, inserts into the carrier A through the through hole, and lifts the component B inside the carrier A.

[0062] Furthermore, the support 21 is provided with a second slider 23 that slides in cooperation with the first slide rail 11, thereby using the sliding of the second slider 23 along the first slide rail 11 to guide the movement of the support 21 relative to the mounting frame 10 in the first direction X.

[0063] Specifically, in this embodiment, the stop assembly 60 includes a mounting block 61 and a stop block 62 fixedly connected to the mounting block 61. The mounting block 61 is movably connected to the mounting frame 10 along a first direction X, so as to drive the stop block 62 to move along the first direction X to or away from the stop position. When the stop block 62 reaches the stop position, the stop block 62 is used to cooperate with the stop of the vehicle A on the passing carrier 21.

[0064] Furthermore, the mounting block 61 is provided with a third slider that slides in cooperation with the first slide rail 11, thereby using the sliding of the third slider along the first slide rail 11 to guide the movement of the mounting base relative to the mounting frame 10 in the first direction X.

[0065] It should be noted that when the mounting block 61 moves to the stop position, it can stop moving by abutting against the flipping assembly 40, thus stopping the mounting block 61 at the stop position. Of course, in other embodiments, a blocking component can also be provided on the first slide rail or mounting bracket to block the mounting block 61 from moving to the stop position, so that the mounting block 61 can stay at the stop position and not continue to move towards the flipping assembly 40.

[0066] In a specific embodiment, the pressing assembly 50 includes a pressing base 51 and a pressing rod 52. The pressing base 51 is movably connected to the mounting bracket 10 along a first direction X. One end of the pressing rod 52 is connected to the pressing base 51, so that the pressing base 51 drives the pressing rod 52 to move together along the first direction X. The other end of the pressing rod 52 extends toward the flipping assembly 40 and is used to abut against element B at the flipping position a.

[0067] Furthermore, the mounting bracket 10 is provided with a second slide rail 12 extending longitudinally along the first direction X, and the lower pressure seat 51 is provided with a fourth slider 54 that slides in cooperation with the second slide rail 12. In this way, the movement of the lower pressure seat 51 relative to the mounting bracket 10 is guided by the sliding of the fourth slider 54 along the second slide rail 12.

[0068] Please see Figures 6 to 9As shown, in an embodiment of the present invention, the flipping assembly 40 includes a mounting plate 41, a first clamping seat 42a, and a second clamping seat 42b. The mounting plate 41 is rotatably connected to the mounting frame 10 about a rotation axis perpendicular to a first direction X. The first clamping seat 42a and the second clamping seat 42b are disposed opposite to each other on the mounting plate 41 and can be controlled to move closer or further away from each other to clamp or release the element B when it reaches the flipping position a. Thus, when the element B is lifted to the flipping position a, the first clamping seat 42a and the second clamping seat 42b are controlled to move closer to each other until the element B is clamped. Then, the mounting plate 41 is controlled to rotate, thereby causing the element B to flip 180°. After flipping to the correct position, the first clamping seat 42a and the second clamping seat 42b are controlled to move further away from each other, thereby releasing the element B so that the element B can be pressed into the carrier A on the bearing assembly 20 by the pressing assembly 50.

[0069] In a specific embodiment, the flipping assembly 40 further includes a gear shaft 43 and a rack 44. The gear shaft 43 is rotatably connected to the mounting bracket 10 and fixedly connected to the mounting plate 41, thereby driving the mounting plate 41 to rotate about a rotation axis. The rack 44 is controllably movably connected to the mounting bracket 10 and meshes with the gear on the gear shaft 43, so that when the rack 44 is moved relative to the mounting bracket 10, it can drive the gear shaft 43 to rotate, and then the gear shaft 43 drives the mounting plate 41 to rotate. Thus, by utilizing the meshing of the gear on the rack 44 and the gear on the gear shaft 43, the linear motion of the rack 44 is converted into the rotational motion of the gear shaft 43. It can be understood that the aforementioned rotation axis is the axis of the gear shaft 43.

[0070] In some embodiments, the flipping assembly 40 further includes a pin 45 controllably movably connected to the mounting bracket 10 along a second direction Y, perpendicular to the first direction X. The pin 45 has a wedge-shaped end 451 extending between a first clamping seat 42a and a second clamping seat 42b. The wedge-shaped end 451 has a first wedge-shaped surface 4511 on the side facing the first clamping seat 42a and a second wedge-shaped surface on the side facing the second clamping seat 42b. The distance between the first wedge-shaped surface 4511 and the second wedge-shaped surface gradually increases or decreases in the second direction Y, such that when the pin 45 moves along the second direction Y, it can use the first wedge-shaped surface 4511 and the second wedge-shaped surface to open up the first clamping seat 42a and the second clamping seat 42b, thereby releasing element B.

[0071] The flipping assembly 40 also includes a second elastic element 425 connected between the first clamping seat 42a and the second clamping seat 42b to provide a preload force that causes the first clamping seat 42a and the second clamping seat 42b to move closer to each other. Thus, when the ejector pin 45 moves out of the space between the first clamping seat 42a and the second clamping seat 42b along the second direction Y, i.e., the wedge end 451 exits the position between the first clamping seat 42a and the second clamping seat 42b, the first clamping seat 42a and the second clamping seat 42b move closer to each other under the action of the second elastic element 425, thereby clamping element B. When the ejector pin 45 moves along the second direction Y between the first clamping seat 42a and the second clamping seat 42b, that is, when the wedge end 451 enters between the first clamping seat 42a and the second clamping seat 42b, the first wedge surface 4511 and the second wedge surface spread apart the first clamping seat 42a and the second clamping seat 42b (at this time, the second elastic member 425 is further stretched), so that the first clamping seat 42a and the second clamping seat 42b move away from each other, thereby releasing element B. Optionally, the second elastic member 425 can be a spring.

[0072] It should be noted that by using the wedge-shaped end 451 of the ejector pin 45 to enter or exit between the first clamping seat 42a and the second clamping seat 42b, the first clamping seat 42a and the second clamping seat 42b can switch from the state of clamping element a to the state of releasing element a. The state switching is fast and flexible, and the structure is simple.

[0073] Furthermore, the flipping assembly 40 also includes a first roller 421 and a second roller 422. The first roller 421 is mounted on the first clamping seat 42a and rolls in engagement with the first wedge surface 4511. The second roller 422 is mounted on the second clamping seat 42b and rolls in engagement with the second wedge surface. Thus, during the process of the wedge-shaped end 451 of the ejector pin 45 entering or exiting between the first clamping seat 42a and the second clamping seat 42b along the second direction Y, the first clamping seat 42a abuts against the first wedge-shaped surface 4511 via the first roller 421, and the second clamping seat 42b abuts against the second wedge-shaped surface via the second roller 422. On the one hand, the sliding friction between the first clamping seat 42a and the first wedge-shaped surface 4511 is converted into rolling friction, and the sliding friction between the second clamping seat 42b and the second wedge-shaped surface is converted into rolling friction, which greatly reduces the wear of the first wedge-shaped surface 4511 and the second wedge-shaped surface and improves the service life. On the other hand, the rolling of the first roller 421 along the first wedge-shaped surface 4511 and the rolling of the second roller 422 along the second wedge-shaped surface are used to drive the first clamping seat 42a and the second clamping seat 42b to move closer or further away from each other, making the clamping and releasing actions of the first clamping seat 42a and the second clamping seat 42b smoother.

[0074] Specifically, in this embodiment, the flipping assembly 40 further includes a limiting block 49 rotatably connected to the mounting plate 41, the limiting block 49 having a limiting groove 491. A first limiting roller 423 is mounted on the first clamping seat 42a, and a second limiting roller 424 is mounted on the second clamping seat 42b, both the first limiting roller 423 and the second limiting roller 424 rollingly engaging within the limiting groove 491. Thus, by using the limiting groove 491 to limit the first limiting roller 423 and the second limiting roller 424, the first clamping seat 42a and the second clamping seat 42b are limited in both the clamped and released states, thereby ensuring that the first clamping seat 42a and the second clamping seat 42b move synchronously during clamping or releasing, i.e., their center positions remain constant, thereby ensuring the concentricity of the component B and the carrier A, and ensuring that the pressing assembly 50 can press the component B back into the carrier A. It should be noted that the rotation axis of the limiting block 49 is parallel to the second direction Y.

[0075] In a specific embodiment, the gear shaft 43 is a hollow shaft, and the ejector pin 45 passes through the gear shaft 43 and is movable along the axial direction (i.e., the second direction Y) of the gear shaft 43. The wedge-shaped end 451 of the ejector pin 45 protrudes from the gear shaft 43 and extends to a position between the first clamping seat 42a and the second clamping seat 42b, so as to facilitate rolling engagement with the first roller 421 and the second roller 422.

[0076] Please see Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the flipping device further includes a turntable and a drive mechanism 2. The turntable is rotatably disposed about a rotation axis parallel to a first direction X. A mounting bracket 10 is mounted on the turntable, such that the mounting bracket 10 rotates together with the turntable. The drive mechanism 2 has a first guide channel b1, a second guide channel b2, and a third guide channel b3, all extending about the rotation axis.

[0077] The lifting assembly 30 has a lifting seat 31 equipped with a first guide wheel 33 that rolls in cooperation with the first guide channel b1. As the turntable drives the mounting frame 10 to rotate around the rotation axis, the first guide wheel 33 rolls along the first guide channel b1. Under the guidance of the first guide channel b1, the first guide wheel 33 drives the lifting assembly 30 to move upward in the first direction X, so that the lifting assembly 30 can complete the action of lifting the component B in the carrier A to the flipping position a.

[0078] Furthermore, a second guide wheel 22 is installed on the support seat 21 of the support assembly 20, which rolls in cooperation with the second guide channel b2. During the rotation of the turntable-driven mounting frame 10 around the rotation axis, the second guide wheel 22 rolls along the second guide channel b2, thereby driving the support assembly 20 to move in the first direction X under the guidance of the second guide channel b2, so as to cooperate with the lifting assembly 30 and the stop assembly 60 to push the component B out of the carrier A to the flipping position a.

[0079] Furthermore, a third guide wheel 53 is mounted on the pressing seat 51 of the pressing assembly 50, which rolls in cooperation with the third guide channel b3. As the turntable drives the mounting bracket 10 to rotate around the rotation axis, the third guide wheel 53 rolls along the third guide channel b3, thereby driving the pressing assembly 50 to move along the first direction X under the guidance of the third guide channel b3, so as to press the element B at the flipped position a back into the carrier A.

[0080] In a specific embodiment, the drive mechanism 2 also has a fourth guide channel b4 extending around the rotation axis. A fourth guide wheel 46 (see [reference needed]) is mounted on the rack 44 and rolls into the fourth guide channel b4. Figure 4 During the rotation of the rotating mounting bracket 10 driven by the turntable around the rotation axis, the fourth guide wheel 46 rolls along the fourth guide channel b4. Under the guidance of the fourth guide channel b4, the fourth guide wheel 46 drives the rack 44 to move along the first direction X, thereby driving the gear shaft 43 and the mounting plate 41 on the gear shaft 43 to rotate, so as to realize the flipping of the component B clamped between the first clamping seat 42a and the second clamping seat 42b.

[0081] In a specific embodiment, the drive mechanism 2 also has a fifth guide channel b5 extending around the rotation axis. A fifth guide wheel 47 (see [reference]) is mounted on the end of the ejector pin 45 opposite to the wedge end 451. Figure 4 The fifth guide wheel 47 rolls in conjunction with the fifth guide channel b5. As the turntable drives the mounting bracket 10 to rotate around the rotation axis, the fifth guide wheel 47 rolls along the fifth guide channel b5. Under the guidance of the fifth guide channel b5, the fifth guide wheel 47 drives the fixed needle to move along the second direction Y. Consequently, the wedge-shaped end 451 of the ejector pin 45 drives the first clamping seat 42a and the second clamping seat 42b to switch between the state of clamping element B and the state of releasing element B.

[0082] Please see Figures 5 to 6 As shown, the mounting bracket 10 is further provided with a third slide rail 13 extending along the second direction Y, and the ejector pin 45 is provided with a fifth slider 481 that slides with the third slide rail 13, thereby using the sliding of the fifth slider 481 along the third slide rail 13 to guide the movement of the ejector pin 45 relative to the mounting bracket 10 along the second direction Y.

[0083] Furthermore, the flipping assembly 40 also includes a third elastic element 48, which is connected to the mounting bracket 10 and the ejector pin 45 to provide a preload force that keeps the fifth guide wheel 47 on the ejector pin 45 abutting against the outer wall of the fifth guide channel b5, thereby preventing the ejector pin 45 from shaking. This allows the first clamping seat 42a and the second clamping seat 42b to clamp and release the element B quickly and to clamp the element B more securely.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
