[0059] The following further illustrates the embodiments of the present application with reference to the accompanying drawings.

[0060] Please refer to Figure 1 , an embodiment of the present application provides a variable pitch and flipping device 100 for changing the pitch between workpieces 200. The workpieces 200 can be in the form of plates, strips, blocks, etc., such as various structural parts that need to be reprocessed, such as aluminum plates, batteries, etc. The variable pitch and flipping device 100 includes a base body 10, a variable pitch mechanism 20, at least two sets of material loading mechanisms 30, and a flipping mechanism 40.

[0061] Specifically, please refer to Figure 1 and Figure 2 , the base body 10 may include a connected support plate 11 and a bracket 12. The support plate 11 may be in the form of a plate structure to provide a stable supporting effect. The bracket 12 may be composed of a plurality of plate structures to provide an activity space for other mechanisms such as the variable pitch mechanism 20 while providing a supporting effect.

[0062] Please refer to Figure 1 、 Figure 2 and Figure 3 , the pitch-changing mechanism 20 includes a first driving member 21 and a rotating member 22 drivingly connected to the first driving member 21. The rotating member 22 is rotatably connected to the seat body 10. A plurality of pitch-changing spiral grooves 221 are provided on the peripheral wall of the rotating member 22 at intervals along the axial direction of the rotating member 22. The two ends of the pitch-changing spiral groove 221 are arranged staggeredly along the axial direction of the rotating member 22. The first driving member 21 can be a cylinder, a stepping motor, etc. The rotating member 22 can be a columnar structure. The number of pitch-changing spiral grooves 221 on the rotating member 22 can be two, three, four, five, etc.

[0063] Please also refer to Figure 4 , each set of loading mechanisms 30 includes a sliding seat 31, a guide post 32 and a positioning assembly 33. The sliding seat 31 is slidably arranged on the seat body 10. The guide post 32 is connected to the side of the sliding seat 31 facing the rotating member 22. The guide post 32 is slidably arranged in the corresponding pitch-changing spiral groove 221. The positioning assembly 33 is rotatably connected to the sliding seat 31 and is used to carry the workpiece 200. The part of the sliding seat 31 slidably connected to the seat body 10 can be arranged as a plate-like structure to improve the stability of the sliding connection between the sliding seat 31 and the seat body 10. The part of the sliding seat 31 connected to the positioning assembly 33 can be provided with two legs to support the positioning assembly 33. The guide post 32 can be a cylindrical structure. In this embodiment, each guide post 32 is arranged in the middle of the side of the sliding seat 31 facing the seat body 10 to improve the stability when the guide post 32 pulls the sliding seat 31 to move. The positioning assembly 33 is used to carry and position the workpiece 200. Therefore, the positioning assembly 33 can be a positioning jig adapted to the workpiece 200 and can fix the workpiece 200. The specific structure is not limited here. The number of loading mechanisms 30 can be two groups, three groups, four groups, five groups, etc. The specific number is subject to actual requirements and is not limited here. It can be understood that the number of loading mechanisms 30 is the same as the number of pitch-changing spiral grooves 221, and the guide post 32 in each loading mechanism 30 is correspondingly arranged in a pitch-changing spiral groove 221.

[0064] It can be understood that the first driving member 21 drives the rotating member 22 to rotate around the axis of the rotating member 22. The pitch-changing spiral groove 221 rotates with the rotating member 22, thereby pulling the guide post 32 to move. The guide post 32 drives the sliding seat 31 to slide along the seat body 10, and the sliding seat 31 further drives the positioning assembly 33 and the workpiece 200 to move with variable pitch.

[0065] Please also refer to Figure 5 and Figure 6, the flipping mechanism 40 includes a second driving member 41 and a transmission assembly 42 drivingly connected to the second driving member 41. The transmission assembly 42 is connected to the positioning assembly 33, and the second driving member 41 is configured to drive the positioning assembly 33 to rotate about its own axis through the transmission assembly 42. The second driving member 41 can be a cylinder or the like. The second driving member 41 drives the transmission assembly 42 to move, and the transmission assembly 42 drives a plurality of positioning assemblies 33 to rotate about their own axes, thereby flipping the workpiece 200.

[0066] In the variable pitch flipping device 100 provided by the embodiment of the present application, the positioning assemblies 33 in at least two sets of loading mechanisms 30 can carry and position a plurality of workpieces 200. By driving the rotating member 22 to rotate through the first driving member 21 in the variable pitch mechanism 20, the guide posts 32 in each loading mechanism 30 can slide along the corresponding variable pitch spiral grooves 221 in the rotating member 22. The variable pitch spiral grooves 221 guide the movement of the guide posts 32, and further pull the sliding seats 31 and the positioning assemblies 33 to slide along the seat body 10, thereby changing the distance between a plurality of workpieces 200. By the second driving member 41 in the flipping mechanism 40, the transmission assembly 42 can be driven to move, and the transmission assembly 42 then drives the positioning assembly 33 to rotate about its own axis, and further drives the workpiece 200 on the positioning assembly 33 to flip, so as to facilitate the processing of the workpiece 200.

[0067] In some embodiments, please refer to Figure 1 and Figure 4 , the positioning assembly 33 includes a rotating shaft 331, a positioning seat 332, a rotating arm 333 and a rotating handle 334.

[0068] The rotating shaft 331 is rotatably connected to the sliding seat 31. The rotating shaft 331 can be a columnar structure, such as a cylinder, etc. It can be understood that in order to facilitate the rotational connection between the rotating shaft 331 and the sliding seat 31, a bearing can be sleeved on the rotating shaft 331. In order to improve the connection stability between the rotating shaft 331 and the sliding seat 31, both ends of the rotating shaft 331 are rotatably connected to the sliding seat 31.

[0069] The positioning seat 332 is connected to the rotating shaft 331 and is used for carrying and positioning the workpiece 200. The positioning seat 332 can be a positioning jig adapted to the workpiece 200, and it is only necessary to be able to fix the workpiece 200. The specific structure is not limited herein.

[0070] The rotating arm 333 is connected to one end of the rotating shaft 331 close to the transmission assembly 42. The rotating arm 333 can be a strip-shaped structure or the like.

[0071] The rotating handle 334 is connected to one end of the rotating arm 333 away from the rotating shaft 331 and is connected to the transmission assembly 42. The rotating arm 333 is eccentrically arranged with respect to the rotating handle 334. The rotating handle 334 can be of a cylindrical structure. It can be understood that after the second driving member 41 drives the transmission assembly 42 to move, the transmission assembly 42 can drive the rotating handle 334 to perform an arc-shaped movement, and the rotating handle 334 then drives the rotating arm 333 to rotate around the axis of the rotating shaft 331, so that the rotating shaft 331 drives the positioning seat 332 and the workpiece 200 to flip.

[0072] In some embodiments, please refer to Figure 1 , Figure 5 and Figure 6 , the transmission assembly 42 includes a transmission member 421 and at least two traction members 422.

[0073] The transmission member 421 is connected to the second driving member 41 and is slidably connected to the seat body 10. The transmission member 421 can be of a plate-like structure. The second driving member 41 is used to drive the transmission member 421 to slide relative to the seat body 10.

[0074] At least two traction members 422 are all connected to the transmission member 421 and are arranged corresponding to the positioning assembly 33 one by one. The traction member 422 is provided with a guiding groove 423. The guiding groove 423 includes a connected first slideway 4231 and a second slideway 4232. The extending direction of the first slideway 4231 is consistent with the axial direction of the rotating member 22. The included angle between the extending direction of the second slideway 4232 and the first slideway 4231 is an obtuse angle, and the second slideway 4232 gradually moves away from the first slideway 4231 and the seat body 10. The number of the traction members 422 can be two, three, four, five, etc. The traction member 422 can be of a plate-like structure. The guiding groove 423 is a strip-shaped groove. Each traction member 422 corresponds to a loading mechanism 30. The rotating handle 334 in each loading mechanism 30 is movably arranged in the guiding groove 423 of the corresponding traction member 422.

[0075] The second driving member 41 is connected to the seat body 10 and is spaced from the rotating member 22 in a direction perpendicular to the axial direction of the rotating member 22.

[0076] Before the pitch change, the rotating handles 334 of the multiple positioning assemblies 33 are all located in the first slideway 4231. After the pitch change, the rotating handles 334 of the multiple positioning assemblies 33 are all located at the connection of the first slideway 4231 and the second slideway 4232. The second driving member 41 drives the transmission member 421 to move. The transmission member 421 drives the rotating handle 334 to rotate around the axis of the rotating shaft 331 through the second slideway 4232. The rotating handle 334 drives the rotating shaft 331 and the positioning seat 332 to rotate through the rotating arm 333, so as to rotate the workpiece 200.

[0077] Please refer to Figure 1It can be understood that when the pitch-changing mechanism 20 drives the multiple loading mechanisms 3020 to change pitch, each loading mechanism 30 moves a different distance. Therefore, before the pitch is changed, the rotating handles 334 in the multiple positioning assemblies 33 are inserted into the first slide 4231 at different positions. In this embodiment, the rotating handle 334 in the positioning assembly 33 farthest from the first driving member 21 is located at the connection between the first slide 4231 and the second slide 4232. The rotating handle 334 in the positioning assembly 33 closest to the first driving member 21 is located at the end of the first slide 4231 away from the second slide 4232. The rotating handles 334 in the other positioning assemblies 33 are located at different positions in the middle of the first slide 4231. Figure 5 When the pitch-changing mechanism 20 drives the multiple loading mechanisms 30 to move and completes the pitch change, the multiple loading mechanisms 30 move away from each other. At this time, the rotating handle 334 in each positioning assembly 33 is located at the connection between the first slide 4231 and the second slide 4232. The second driving member 41 drives the multiple traction members 422 to move via the transmission member 421. The traction members 422 push the rotating handle 334 along the second slide 4232. Because the rotating handle 334 is connected to the rotating arm 333, and the rotating arm 333 is connected to the rotating shaft 331, the position of the rotating shaft 331 remains unchanged. Therefore, when the rotating handle 334 slides along the second slide 4232, it moves in an arc around the axis of the rotating shaft 331231. The rotating arm 333 then drives the rotating shaft 331 to rotate, thereby driving the positioning seat 332 to rotate, thereby achieving the purpose of flipping the workpiece 200 on the positioning seat 332.

[0078] In some embodiments, see Figure 2 、 Figure 3 and Figure 4 Each variable-pitch spiral groove 221 includes an opposing first end 2211 and a second end 2212. The first ends 2211 and second ends 2212 of the variable-pitch spiral grooves 221 are located on the same straight line, and the spacing between two adjacent first ends 2211 is smaller than the spacing between two adjacent second ends 2212. In this way, when the rotating member 22 rotates, the multiple variable-pitch spiral grooves 221 can drive the multiple guide posts 32 to move synchronously, thereby causing the variable pitch mechanism 20 to move synchronously. The spacing between two adjacent first ends 2211 is smaller than the spacing between two adjacent second ends 2212. This ensures that the spacing between two adjacent loading mechanisms 30 when each guide post 32 is located at the first end 2211 of the corresponding variable-pitch spiral groove 221 is smaller than the spacing between two adjacent loading mechanisms 30 when each guide post 32 is located at the second end 2212 of the corresponding variable-pitch spiral groove 221.

[0079] In some embodiments, see Figure 2 、 Figure 3 and Figure 4, the rotating member 22 is further provided with an annular groove 222. The annular groove 222 is arranged at one end of the rotating member 22 away from the first driving member 21, and the annular groove 222 corresponds to a set of material loading mechanisms 30 away from the first driving member 21. In this way, when the rotating member 22 rotates, the position of the material loading mechanism 30 on the end of the rotating member 22 away from the first driving member 21 relative to the first driving member 21 can be kept unchanged. It can be understood that the purpose of the variable pitch mechanism 20 driving the plurality of material loading mechanisms 30 to move away from or close to each other is to change the distance between two adjacent material loading mechanisms 30. Therefore, it is only necessary to keep the position of the material loading mechanism 30 on the end of the rotating member 22 away from the first driving member 21 relative to the first driving member 21 unchanged.

[0080] In some embodiments, please refer to Figure 5 and Figure 6 , the guiding groove 423 further includes a third slideway 4233. The third slideway 4233 is connected to one end of the second slideway 4232 away from the first slideway 4231, and the third slideway 4233 is arranged along the axial direction of the rotating member 22. It can be understood that when the flipping mechanism 40 drives the positioning assembly 33 to complete rotation, the rotating handle 334 of the positioning assembly 33 is located at one end of the second slideway 4232 away from the first slideway 4231. If the workpiece 200 is processed at this time, there is a risk of rotation of the positioning assembly 33, that is, the rotating handle 334 is likely to move along the second slideway 4232 towards the first slideway 4231 at this time, which will cause poor processing. By providing the third slideway 4233, after the rotating handle 334 moves to one end of the second slideway 4232 away from the first slideway 4231, the second driving member 41 drives the plurality of traction members 422 to continue to move, so that the rotating handle 334 enters the third slideway 4233. The groove wall of the third slideway 4233 can hold the rotating handle 334, avoiding the rotation of the positioning assembly 33 when processing the workpiece 200 and improving the production yield.

[0081] In some embodiments, please refer to Figure 4 , Figure 5 and Figure 6 , the material loading mechanism 30 further includes a first limiting member 35. The first limiting member 35 is connected to one end of the sliding seat 31 close to the transmission member 421 and is arranged on the side of the sliding seat 31 facing the first driving member 21. The first limiting member 35 is arranged at a horizontal interval from the rotating arm 333. The first limiting member 35 is used to abut against the rotating arm 333 when the rotating handle 334 moves to the first slideway 4231 to limit the rotating arm 333. In this way, when the flipping mechanism 40 drives the rotating handle 334 to move to the first slideway 4231, the first limiting member 35 can limit the rotating arm 333 by abutting against the rotating arm 333, avoiding excessive rotation of the rotating arm 333 and improving the position accuracy of the rotating shaft 331 and the positioning seat 332 after rotation.

[0082] In some embodiments, please refer toFigure 4 、 Figure 5 and Figure 6 The loading mechanism 30 further includes a second stopper 36 connected to one end of the sliding seat 31 near the transmission member 421 and disposed on a side of the sliding seat 31 facing away from the seat body 10. The second stopper 36 is vertically spaced from the rotating arm 333 and is configured to abut against the rotating arm 333 when the rotating handle 334 moves to the third slideway 4233, thereby limiting the position of the rotating arm 333. Thus, when the flip mechanism 40 drives the rotating handle 334 to move to the third slideway 4233, the second stopper 36 abuts against the rotating arm 333 to limit the position of the rotating arm 333, preventing the rotating arm 333 from excessively rotating and improving the positional accuracy of the rotating shaft 331 and the positioning seat 332 after rotation.

[0083] In some embodiments, see Figure 1 and Figure 2 The base 10 further includes a first slide rail 13 and a second slide rail 14. The first slide rail 13 is disposed on a side of the base 10 near the sliding seat 31, and the sliding seat 31 is slidably connected to the base 10 via the first slide rail 13. The second slide rail 14 is disposed on a side of the base 10 near the second driving member 41, and the transmission member 421 is slidably connected to the base 10 via the second slide rail 14. The provision of the first slide rail 13 can improve the stability of the movement of the loading mechanism 30 on the base 10, and the provision of the second slide rail 14 can improve the stability of the movement of the transmission member 421 on the base 10.

[0084] In some embodiments, see Figure 1 、 Figure 2 and Figure 4 The loading mechanism 30 further includes a plurality of rotating bearings 34. The plurality of rotating bearings 34 are disposed on the side of the sliding seat 31 facing the seat body 10 and are disposed one-to-one with the plurality of guide posts 32. Each guide post 32 is rotatably connected to the sliding seat 31 via a corresponding rotating bearing 34. It is understood that when the rotating member 22 rotates, the groove wall of the variable-pitch spiral groove 221 pushes against the guide post 32 to move. At this time, friction occurs between the groove wall of the variable-pitch spiral groove 221 and the guide post 32. By providing the rotating bearings 34, the guide post 32 itself can rotate when the variable-pitch spiral groove 221 pushes against the guide post 32 to move, thereby reducing friction between the guide post 32 and the variable-pitch spiral groove 221 and improving its service life.

[0085] The working process of the variable pitch flipping device 100 provided in the embodiment of the present application is roughly as follows:

[0086] See Figure 1, before installing the workpiece 200 into the positioning seat 332, the guiding columns 32 in each loading mechanism 30 are located at the first end 2211 of the corresponding variable pitch spiral groove 221, and the rotating handles 334 in each loading mechanism 30 are located at the first slideway 4231 of the guiding groove 423. At this time, the rotating arms 333 are all abutted against the first limiting member 35.

[0087] Then, install the workpiece 200 into the positioning seat 332. After the installation of the workpiece 200 is completed, please refer to Figure 5 , the first driving member 21 drives the rotating member 22 to rotate. The guiding columns 32 in each loading mechanism 30 slide along the variable pitch spiral groove 221 until they slide to the second end 2212 of the corresponding variable pitch spiral groove 221. At this time, the multiple loading mechanisms 30 move away from each other, completing the variable pitch of the workpiece 200, and the rotating handles 334 in each loading mechanism 30 are all located at the connection of the first slideway 4231 and the second slideway 4232.

[0088] Please refer to Figure 6 , when it is necessary to rotate the workpiece 200, the second driving member 41 in the flipping mechanism 40 drives a plurality of traction members 422 to move through the transmission member 421. The traction members 422 push the rotating handle 334 to move. Since the rotating handle 334 is connected to the rotating arm 333, and the rotating arm 333 is connected to the rotating shaft 331, and the position of the rotating shaft 331 remains unchanged. Therefore, the rotating handle 334 slides along the second slideway 4232 during the movement, that is, makes an arc movement around the axis of the rotating shaft 331. Furthermore, the rotating shaft 331 is driven to rotate through the rotating arm 333 to drive the positioning seat 332 to rotate, thereby flipping the workpiece 200. After the rotating handle 334 moves to the end of the second slideway 4232 far from the first slideway 4231, the rotating arm 333 abuts against the second limiting member 36, and the traction member 422 continues to move, so that the third slideway 4233 clamps the rotating handle 334, thereby limiting the rotating handle 334 and improving the stability of the position of the workpiece 200.
