Description

Technical Field

[0001] The present application relates to the technical field of battery production equipment, and in particular to a flipping device. Background Art

[0002] During the manufacturing process of some products, a flipping device is required to flip the product to facilitate subsequent operations on the product. For example, if the product is a battery cell, the flipping device is required to flip the battery cell so that the battery cell can be matched with the other cells.

[0003] To ensure stable flipping, conventional flipping devices can only flip one or two groups of cells, resulting in low efficiency. Increasing the number of cells flipped can lead to unstable flipping. Therefore, a flipping device that can both increase the number of cells flipped and improve flipping stability has become an urgent issue. Utility Model Content

[0004] Based on this, it is necessary to provide a flipping device that can increase the number of flips and improve the stability of flipping to address the above problems.

[0010] Wherein, the preset direction intersects with the lifting direction of the flip mechanism.

[0011] In some of these embodiments, the clamping mechanism includes a first clamping assembly and a second clamping assembly. The first clamping assembly and the second clamping assembly are distributed on opposite sides of the clamping station along a direction that intersects both the preset direction and the lifting direction of the flipping mechanism. The first clamping assembly and the second clamping assembly cooperate and are used to clamp or release the workpiece to be flipped at each clamping station along the lifting direction of the flipping mechanism and / or along a direction that intersects both the preset direction and the lifting direction of the flipping mechanism.

The first clamping units are installed on the first fixing bracket and correspond to the clamping stations one by one.

[0013] The second clamping assembly includes a second driving member, a second fixing bracket, and a plurality of second clamping units. The second driving member is installed on the flipping component and is in transmission connection with the second fixing bracket. The second clamping units are installed on the second fixing bracket and correspond to the clamping stations one by one.

[0014] The first fixing bracket and the second fixing bracket open or close under the combined action of the first driving member and the second driving member. When the first fixing bracket and the second fixing bracket close, the first clamping units and the second clamping units clamp the workpiece to be flipped at the corresponding clamping stations along a direction that intersects both the preset direction and the lifting direction of the flipping mechanism.

[0015] In some of these embodiments, the first clamping unit includes a third driving member and a first clamping member. The third driving member is installed on the first fixing bracket and is used to drive the first clamping member to clamp or release the workpiece to be flipped along the lifting direction of the flipping mechanism; and / or

[0016] The second clamping unit includes a fourth driving member and a second clamping member. The fourth driving member is installed on the second fixing bracket and is used to drive the second clamping member to clamp or release the workpiece to be flipped along the lifting direction of the flipping mechanism.

[0017] In some of these embodiments, a wire routing hole is formed in the flipping component.

[0018] The first driving member, the second driving member, the third driving member, and the fourth driving member are all air cylinders or electric cylinders. The air pipes of the first driving member, the second driving member, the third driving member, and the fourth driving member or the wires electrically connected to an external power source are threaded through the wire routing hole and led out from the wire routing hole.

[0019] In some of these embodiments, the rack is further connected with a corrugated beam tube, and the corrugated beam tube is used to tighten the air pipes or wires of the first driving member, the second driving member, the third driving member and the fourth driving member.

[0020] In some of these embodiments, a limit and buffer mechanism is further included. The limit and buffer mechanism is arranged on the flipping member and includes a first limit and buffer component and a second limit and buffer component.

[0025] For the above-mentioned flipping device, the flipping member is rotatably installed between the first mounting frame and the second mounting frame, and the first lifting mechanism is in transmission connection with the first mounting frame, and the second lifting mechanism is in transmission connection with the second mounting frame. In this way, during the actual working process, the first lifting mechanism and the second lifting mechanism can be located at both ends of the flipping member to support and drive the flipping member, so that the flipping stability of the flipping member is better. In this case, even if a plurality of clamping stations, such as four clamping stations, are designed on the flipping member along a preset direction, the flipping mechanism can also stably drive the clamping mechanism and the workpieces to be flipped at all clamping stations to flip. While the number of flips can be increased, the flipping stability can also be improved, and the flipping efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0046] Please refer to Figure 1 、 Figure 2 and Figure 3 together. The present application provides a flipping device 1 for flipping a workpiece to be flipped. The workpiece to be flipped can be a battery cell 2, a battery tray or other components, which are not specifically limited herein.

[0047] The flipping device 1 includes a frame 10, a flipping mechanism 20, a first lifting mechanism 30, a second lifting mechanism 40 and a clamping mechanism 50. The frame 10 is used to mount the first lifting mechanism 30 and the second lifting mechanism 40. The flipping mechanism 20 is mounted on both the first lifting mechanism 30 and the second lifting mechanism 40 at the same time. The clamping mechanism 50 is mounted on the flipping mechanism 20. The first lifting mechanism 30 and the second lifting mechanism 40 synchronously drive the flipping mechanism 20 to lift, and the flipping mechanism 20 drives the clamping mechanism 50 to flip. The clamping mechanism 50 is used to clamp the workpiece to be flipped.

[0048] Among them, the frame 10 can be made of materials with better mechanical strength such as stainless steel and sheet metal. The frame 10 can be in the shape of a "door" or a "cross" or other shapes, which are not specifically limited herein.

[0049] The flipping mechanism 2 includes a first mounting bracket 21, a second mounting bracket 22 and a flipping assembly 23. The first mounting bracket 21 and the second mounting bracket 22 are arranged at intervals along a preset direction X. The flipping assembly 23 includes a flipping member 231. The flipping member 231 is rotatably mounted between the first mounting bracket 21 and the second mounting bracket 22, and a plurality of clamping stations 237 are arranged at intervals along the preset direction X on the flipping member 231. The clamping mechanism 50 is arranged on the flipping member 231 and is used to clamp the workpiece to be flipped located at each clamping station 237.

[0050] Exemplarily, the outer contours of the first mounting bracket 21 and the second mounting bracket 22 are substantially the same to facilitate the machining of the first mounting bracket 21 and the second mounting bracket 22. For example, both the first mounting bracket 21 and the second mounting bracket 22 are plate-shaped or cantilever-shaped.

[0051] Exemplarily, the flipping member 231 may be a shaft structure and only include a shaft portion 231a; alternatively, the flipping member 231 may also include a shaft portion 231a and a mounting portion 231b, and the shaft portion 231a is disposed at opposite ends of the mounting portion 231b along a preset direction X; alternatively, the flipping member 231 may also include a shaft portion 231a and a mounting portion 231b, and the mounting portion 231b is disposed on the top side of the shaft portion 231a; the shaft portion 231a is controlled to drive the mounting portion 231b to flip, and the mounting portion 231b is used for mounting the clamping mechanism 50.

[0052] In some alternative embodiments, the flipping assembly 23 further includes a flipping driving member 232, a flipping driving wheel 233, a flipping driven wheel 234, and a flipping synchronous belt 235. The flipping driving member 232 is mounted on the first mounting bracket 21 and is in transmission connection with the flipping driving wheel 233. The flipping driven wheel 234 is sleeved on the flipping member 231. Taking the flipping member 231 having a shaft portion 231a and a mounting portion 231b as an example, the flipping driven wheel 234 is sleeved and fixed on the shaft portion 231a, and the flipping synchronous belt 235 is sleeved outside the flipping driving wheel 233 and the flipping driven wheel 234.

[0053] The power of the flipping driving member 232 is sequentially transmitted to the flipping member 231 through the flipping driving wheel 233, the flipping synchronous belt 235, and the flipping driven wheel 234. This power transmission method has stable power transmission and is beneficial to improving the stability and reliability of flipping.

[0054] Exemplarily, the flipping driving member 232 may be a motor, a servo motor, or the like.

[0055] In some alternative embodiments, the flipping driving member 232 is located on the side of the second mounting bracket 22 facing the first mounting bracket 21, and the flipping driving wheel 233, the flipping driven wheel 234, and the flipping synchronous belt 235 are located on the side of the second mounting bracket 22 facing away from the first mounting bracket 21. Generally, the flipping driving member 232 occupies a relatively large space. When the flipping driving member 232 is disposed on the side of the second mounting bracket 22 facing the first mounting bracket 21, that is, the flipping driving member 232 is located between the first mounting bracket 21 and the second mounting bracket 22. In this way, in the preset direction X, the flipping driving member 232 and the flipping member 231 share the space, which is beneficial to reducing the space occupied by the flipping device 1 in the preset direction X.

[0056] In some alternative embodiments, the flipping mechanism 20 further includes a tensioning wheel 236. The tensioning wheel 236 is rotatably disposed on the first mounting bracket 21 and is used for tensioning the flipping synchronous belt 235. By providing the tensioning wheel 236, the flipping synchronous belt 235 can maintain a certain tension during movement, so as to ensure that the flipping synchronous belt 235 drives the flipping driven wheel 234 to rotate, and ultimately achieve the purpose of driving the clamping mechanism 50 to flip by the flipping member 231.

[0057] Of course, in some other alternative embodiments, the structure of the flipping component 23 is not limited to the above-mentioned one, and it can also be in other forms. For example, the flipping component 23 only includes a flipping driving member 232 and a flipping member 231, and the flipping driving member 232 drives the flipping member 231 to flip.

[0058] The first lifting mechanism 30 and the second lifting mechanism 40 are both installed on the frame 10. The first lifting mechanism 30 is in transmission connection with the first mounting bracket 21, and the second lifting mechanism 40 is in transmission connection with the second mounting bracket 22. The first lifting mechanism 30 and the second lifting mechanism 40 cooperate and synchronously drive the flipping mechanism 20 to lift.

[0059] Among them, the preset direction X intersects with the lifting direction Y of the flipping mechanism 20. Taking Figure 1 the state of the flipping device 1 as an example, the preset direction X is the horizontal direction set left and right, and the lifting direction is the vertical direction.

[0060] Exemplarily, the first lifting mechanism 30 includes a first lifting driving member 31 and a first guide rail 32. The first mounting bracket 21 is slidably mounted on the first guide rail 32, and the first lifting driving member 31 is connected to the first mounting bracket 21; the second lifting mechanism 40 includes a second lifting driving member 41 and a second guide rail 42. The second mounting bracket 22 is slidably mounted on the second guide rail 42, and the second lifting driving member 41 is connected to the second mounting bracket 22. Among them, the first lifting driving member 31 and the second lifting driving member 41 can be cylinders or electric cylinders, etc., and are not specifically limited here.

[0061] In the present application, the flipping member 231 is rotatably mounted between the first mounting bracket 21 and the second mounting bracket 22, and the first lifting mechanism 30 is in transmission connection with the first mounting bracket 21, and the second lifting mechanism 40 is in transmission connection with the second mounting bracket 22. In this way, during the actual working process, the first lifting mechanism 30 and the second lifting mechanism 40 can be located at both ends of the flipping member 231 to support and drive the flipping member 231, so that the stability of the flipping of the flipping member 231 is better. In this case, even if a plurality of clamping stations 237 are designed on the flipping member 231 along the preset direction X, such as four clamping stations 237, the flipping mechanism 231 can also stably drive the clamping mechanism 50 and the workpieces to be flipped at all the clamping stations 237 to flip. While the number of flips can be increased, the stability of flipping can also be improved, and the flipping efficiency is high.

[0062] The clamping mechanism 50 is disposed on the flipping member 231 and includes a first clamping assembly 51 and a second clamping assembly 52. The first clamping assembly 51 and the second clamping assembly 52 are distributed on opposite sides of the clamping station 237 along a direction Z that intersects both the preset direction X and the lifting direction Y of the flipping mechanism 20. The first clamping assembly 51 and the second clamping assembly 52 cooperate and are used to clamp or release the workpiece to be flipped at each clamping station 237 along the lifting direction Y of the flipping mechanism 20 and / or along the direction Z that intersects both the preset direction X and the lifting direction Y of the flipping mechanism 20.

[0063] Taking Figure 2 the state of the flipping device 1 as an example, the direction Z that intersects both the preset direction X and the lifting direction Y of the flipping mechanism 20 is the vertical direction, and the preset direction X is the horizontal direction set left and right. Taking the workpiece to be flipped as the battery cell 2 as an example, the lifting direction Y of the flipping mechanism 20 is the thickness direction of the battery cell 2, and the direction Z that intersects both the preset direction X and the lifting direction Y of the flipping mechanism 20 is the width direction of the battery cell 2.

[0064] By providing the first clamping assembly 51 and the second clamping assembly 52, the clamping mechanism 50 can clamp or release the workpiece to be flipped along at least one direction, enabling relative fixation or separation between the clamping mechanism 50 and the workpiece to be flipped. When the clamping mechanism 50 and the workpiece to be flipped are relatively fixed, the clamping mechanism 50 can drive the workpiece to be flipped under the drive of the flipping member 231. When the clamping mechanism 50 and the workpiece to be flipped are relatively separated, the workpiece to be flipped can be conveyed to the next process.

[0065] In some alternative embodiments, the first clamping assembly 51 includes a first driving member 511, a first fixing frame 512, and a plurality of first clamping units 513. The first driving member 511 is installed on the flipping member 231 and is in transmission connection with the first fixing frame 512. The first clamping units 513 are installed on the first fixing frame 512 and correspond to the clamping stations 237 one by one;

[0066] The second clamping assembly 52 includes a second driving member 521, a second fixing frame 522, and a plurality of second clamping units 523. The second driving member 521 is installed on the flipping member 231 and is in transmission connection with the second fixing frame 522. The second clamping units 523 are installed on the second fixing frame 522 and correspond to the clamping stations 237 one by one;

[0067] The first fixing frame 512 and the second fixing frame 522 open or close under the combined action of the first driving member 511 and the second driving member 521. The first clamping units 513 and the second clamping units 523 clamp the workpiece to be flipped at the corresponding clamping stations 237 along the direction Z that intersects both the preset direction X and the lifting direction Y of the flipping mechanism 20 when the first fixing frame 512 and the second fixing frame 522 close.

[0068] The power of the first driving member 511 is transmitted to each first clamping unit 513 through the first fixing bracket 512, and the power of the second driving member 521 is transmitted to each second clamping unit 523 through the second fixing bracket 522. The first clamping units 513 and the second clamping units 523 are set in a set, and the first clamping units 513 and the second clamping units 523 in the set correspond to the same clamping station 237.

[0069] When the first driving member 511 and the second driving member 521 cooperate and drive the first fixing bracket 512 and the second fixing bracket 522 to close, the first clamping units 513 and the second clamping units 523 in the set clamp the workpiece to be flipped at the corresponding clamping station 237. When the first driving member 511 and the second driving member 521 cooperate and drive the first fixing bracket 512 and the second fixing bracket 522 to open, the distance between the first clamping units 513 and the second clamping units 523 in the set increases. On the one hand, the first clamping units 513 and the second clamping units 523 can be separated from the workpiece to be flipped to facilitate the workpiece to be flipped to enter the subsequent manufacturing process. On the other hand, there is a large distance between the first clamping units 513 and the second clamping units 523 to facilitate the first clamping units 513 and the second clamping units 523 to adapt to workpieces to be flipped with different sizes next time.

[0070] In summary, by providing that the first clamping assembly 51 includes a first driving member 511, a first fixing bracket 512 and a plurality of first clamping units 513, and the second clamping assembly 52 includes a second driving member 521, a second fixing bracket 522 and a plurality of second clamping units 523, the workpiece to be flipped can be clamped from both sides, and the clamping effect is good.

[0071] In some alternative embodiments, the first clamping unit 513 includes a third driving member 513a and a first clamping member 513b. The third driving member 513a is installed on the first fixing bracket 512 and is used to drive the first clamping member 513b to clamp or release the workpiece to be flipped along the lifting direction Y of the flipping mechanism 20; and / or, the second clamping unit 523 includes a fourth driving member 523a and a second clamping member 523b. The fourth driving member 523a is installed on the second fixing bracket 522 and is used to drive the second clamping member 523b to clamp or release the workpiece to be flipped along the lifting direction Y of the flipping mechanism 20.

[0072] Taking the workpiece to be flipped as the battery cell 2 as an example, the thickness direction of the battery cell 2 overlaps with the lifting direction Y of the flipping mechanism 20. The first clamping member 513b and the second clamping member 523b corresponding to the same clamping station 237 cooperate to be able to clamp or release the battery cell 2 in the width direction and the thickness direction of the battery cell 2.

[0073] Exemplarily, the first driving member 511, the second driving member 521, the third driving member 513a, and the fourth driving member 523a can all be cylinders, electric cylinders, etc., and can be specifically set according to requirements.

[0074] Exemplarily, the first clamping member 513b includes two first clamping plates oppositely arranged along the lifting direction Y of the flipping mechanism 20. One of the first clamping plates is fixed to the first fixing frame 512, and the third driving member 513a is connected to the other first clamping plate. When the third driving member 513a drives the other first clamping plate to approach one of the first clamping plates, the two first clamping plates cooperate and can clamp the workpiece to be flipped. When the third driving member 513a drives the other first clamping plate to move away from one of the first clamping plates, the two first clamping plates release the workpiece to be flipped.

[0075] Exemplarily, the second clamping member 523b includes two second clamping plates oppositely arranged along the lifting direction Y of the flipping mechanism 20. One of the second clamping plates is fixed to the second fixing frame 522, and the fourth driving member 523a is connected to the other second clamping plate. When the fourth driving member 523a drives the other second clamping plate to approach one of the second clamping plates, the two second clamping plates cooperate and can clamp the workpiece to be flipped. When the fourth driving member 523a drives the other second clamping plate to move away from one of the second clamping plates, the two second clamping plates release the workpiece to be flipped. By providing the first clamping unit 513 with the third driving member 513a and the first clamping member 513b, and the second clamping unit 523 including the fourth driving member 523a and the second clamping member 523b, when the first driving member 511, the second driving member 521, the third driving member 513a, and the fourth driving member 523a work simultaneously, the clamping mechanism 50 can clamp the workpiece to be flipped from two directions of the workpiece to be flipped, and has a good clamping effect.

[0076] Of course, the structures of the first clamping unit 513 and the second clamping unit 523 are not limited to the above one. In some other embodiments, for example, the first clamping unit 513 can further include two third driving members 513a. The two third driving members 513a correspond to the two first clamping plates one by one. Each third driving member 513a is connected to the corresponding first clamping plate. When the two third driving members 513a work, the two first clamping plates clamp or release the workpiece to be flipped along the lifting direction Y of the flipping mechanism 20; the second clamping unit 523 can further include two fourth driving members 523a. The two fourth driving members 523a correspond to the two second clamping plates one by one. Each fourth driving member 523a is connected to the corresponding second clamping plate. When the two fourth driving members 523a work, the two second clamping plates clamp or release the workpiece to be flipped along the lifting direction Y of the flipping mechanism 20.

[0077] Please refer to again Figure 1 and Figure 2, in some alternative embodiments, a wire routing hole 231c is formed on the flipping member 231; specifically, the wire routing hole 231c is provided on the mounting portion 231b of the flipping member 231. The first driving member 511, the second driving member 521, the third driving member 513a, and the fourth driving member 523a are all air cylinders or electric cylinders, and the air pipes or wires electrically connected to an external power source of the first driving member 511, the second driving member 521, the third driving member 513a, and the fourth driving member 523a are threaded through the wire routing hole 231c and led out from the wire routing hole 231c.

[0078] With the design of the wire routing hole 231c, the wire routing hole 231c can regularize and restrain the air pipes or wires electrically connected to an external power source of the first driving member 511, the second driving member 521, the third driving member 513a, and the fourth driving member 523a, so as to prevent various air pipes or wires from being entangled or scattered and affecting the normal operation of the flipping device 1.

[0079] Exemplarily, the wire routing hole 231c is provided at one end of the flipping member 231 away from the flipping driving member 232 in a preset direction X.

[0080] It is worth mentioning that the wire electrically connected to an external power source of the flipping driving member 232 can be selectively passed through the wire routing hole 231c.

[0081] Furthermore, in some alternative embodiments, the frame 10 is further connected with a corrugated tube for bundling the air pipes or wires of the first driving member 511, the second driving member 521, the third driving member 513a, and the fourth driving member 523a.

[0082] With the design of the corrugated tube, it can further regularize and restrain the air pipes or wires electrically connected to an external power source of the first driving member 511, the second driving member 521, the third driving member 513a, and the fourth driving member 523a.

[0083] Among them, the corrugated tube is installed on the frame 10 at one end away from the flipping driving member 232 in the preset direction X through a rod member 12.

[0084] It is worth mentioning that the air pipes or wires electrically connected to an external power source of the first lifting driving member 31 and the second lifting driving member 41 can be selectively passed through or not passed through the corrugated tube.

[0085] Please refer to again Figure 1 , Figure 2 and Figure 3 , and refer to simultaneously Figure 4 and Figure 5, in some alternative embodiments, the flipping device 1 further includes a limit buffering mechanism 60. The limit buffering mechanism 60 is disposed on the flipping member 231 and includes a first limit buffering component 61 and a second limit buffering component 62. The first limit buffering component 61 is located on the side of the first fixing bracket 512 facing away from the second fixing bracket 522, and the second limit buffering component 62 is located on the side of the second fixing bracket 522 facing away from the first fixing bracket 512; the first limit buffering component 61 and the second limit buffering component 62 cooperate to limit the opening amplitude of the first fixing bracket 512 and the second fixing bracket 522.

[0086] Wherein, both the first limit buffering component 61 and the second limit buffering component 62 can be one or multiple, and all the first limit buffering components 61 and all the second limit buffering components 62 are arranged at intervals along the preset direction X.

[0087] By providing the first limit buffering component 61 and the second limit buffering component 62, when the first fixing bracket 512 and the second fixing bracket 522 are opened to a certain amplitude, the first fixing bracket 512 abuts against the first limit buffering component 61, and the second fixing bracket 522 abuts against the second limit buffering component 62 to prevent the first fixing bracket 512 and the second fixing bracket 522 from continuing to move, thereby ensuring that the opening amplitude of the first fixing bracket 512 and the second fixing bracket 522 is within a suitable range. It can be understood that if the opening amplitude of the first fixing bracket 512 and the second fixing bracket 522 is too large, the distance that the first fixing bracket 512 and the second fixing bracket 522 need to move when they close next time is also large, and the time is long, which is likely to cause a reduction in the working efficiency of the flipping device 1. When the opening amplitude of the first fixing bracket 512 and the second fixing bracket 522 is within a suitable range, the first fixing bracket 512 and the second fixing bracket 522 can close quickly, so that the next batch of workpieces to be flipped can be quickly clamped, and the working efficiency is improved.

[0088] As an example, both the first limit buffering component 61 and the second limit buffering component 62 can be limit buffering rods that are telescopic along the direction in which the first clamping component 51 and the second clamping component 52 clamp the workpiece to be flipped. Of course, the first limit buffering component 61 and the second limit buffering component 62 can also be other limit forms, which are not specifically limited here.

[0089] Next, taking the workpiece to be flipped as the battery cell 2 and the flipping device 1 being used to flip the battery cell 2 as an example for illustration.

[0090] The battery cell 2 is transferred to the flipping station (the station where the flipping device 1 in this application is located) through the logistics pull belt (not shown in the figure), and the battery cell 2 is positioned by the positioning fixture on the logistics pull belt (not shown in the figure). Then, the first lifting mechanism 30 and the second lifting mechanism 40 synchronously drive the flipping mechanism 20 and the clamping mechanism 50 to descend to the position where the battery cell 2 is located, and clamp the battery cell 2. In order to improve the flipping efficiency, each clamping station 237 needs to clamp a battery cell 2. After the clamping is completed, the first lifting mechanism 30 and the second lifting mechanism 40 drive the flipping mechanism 20, the clamping mechanism 50 and the battery cell 2 to rise to a height where flipping is possible. Then, the flipping mechanism 20 drives the clamping mechanism 50 to clamp the battery cell 2 to complete the flipping action. After that, the first lifting mechanism 30 and the second lifting mechanism 40 drive the flipping mechanism 20, the clamping mechanism 50 and the battery cell 2 to descend to the position where the battery cell 2 was before clamping. The clamping mechanism 50 releases the battery cell 2 and places the battery cell 2 on the logistics pull belt.

[0091] In the above-mentioned flipping device 1, the flipping component 231 is rotatably mounted between the first mounting frame 21 and the second mounting frame 22, and the first lifting mechanism 30 is transmission-connected to the first mounting frame 21, and the second lifting mechanism 40 is transmission-connected to the second mounting frame 22. In this way, during actual operation, the first lifting mechanism 30 and the second lifting mechanism 40 can be located at both ends of the flipping component 231 and support and drive the flipping component 231, so that the flipping stability of the flipping component 231 is improved. In this case, even if multiple clamping stations 237, such as four clamping stations 237, are designed along the preset direction X on the flipping component 231, the flipping mechanism 231 can stably drive the clamping mechanism 50 and the parts to be flipped at all the clamping stations 237 to flip, thereby increasing the number of flips while also improving the stability of the flips and achieving high flipping efficiency.

[0092] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0093] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
