[0023] The embodiments of this application will be further described below with reference to the accompanying drawings. To facilitate understanding and explanation of the embodiments of this application, a coordinate system is established in some of the drawings, with the Y-axis as the first direction, the X-axis as the second direction, and the Z-axis as the third direction. The X-axis, Y-axis, and Z-axis are mutually perpendicular.

[0024] Please see Figure 1 , Figure 2 and Figure 3 This application provides a flipping and positioning device 100. The flipping and positioning device 100 is used to flip and position a workpiece 200, which can be a strip-shaped or sheet-shaped structural component. The flipping and positioning device 100 includes a flipping mechanism 10, a transfer and pitch-changing mechanism 20, and a positioning mechanism 30.

[0025] Specifically, the flipping mechanism 10 includes a flipping component 11 and a stop component 12. The flipping component 11 includes a flipping drive 111 and a flipping component 112 connected to the flipping drive 111. The flipping component 112 is provided with a plurality of loading slots 1121 for accommodating the workpiece 200. The stop component 12 is connected to the flipping component 112 and is used to stop or release the workpiece 200 located in the loading slot 1121. The flipping drive 111 is configured to drive the flipping component 112 to rotate around a first direction to flip the workpiece 200.

[0026] The flipping drive 111 can be a rotary cylinder, rotary motor, etc., and the flipping component 112 can be a plate-like structure. The structure of the material loading groove 1121 is adapted to the structure of the workpiece 200. The number of material loading grooves 1121 can be two, three, four, etc., depending on actual needs and is not limited here. It can be understood that when the flipping assembly 11 receives the workpiece 200, the flipping drive 111 drives the flipping component 112 to rotate so that the material loading groove 1121 faces upwards. The workpiece 200 is then placed in the material loading groove 1121 by an external feeding device (not shown), such as a robotic arm. Before flipping, the baffle assembly 12 operates to stop the workpiece 200 in the material loading groove 1121, preventing the workpiece 200 from slipping during the flipping process. The flipping drive 111 drives the flipping component 112 to rotate 180° around the first direction, completing the flipping of the workpiece 200.

[0027] The transfer and pitch-changing mechanism 20 includes a transfer component 21 and a pitch-changing component 22 connected to the transfer component 21. The transfer component 21 is arranged adjacent to the flipping mechanism 10 along the second direction. The transfer component 21 is used to drive the pitch-changing component 22 to move along the second direction. The pitch-changing component 22 includes a pitch-changing drive member 221 connected to the transfer component 21 and a plurality of positioning seats 222 connected to the pitch-changing drive member 221. The plurality of positioning seats 222 are arranged along the first direction. The pitch-changing drive member 221 is configured to drive the plurality of positioning seats 222 to move closer to or further away from each other along the first direction.

[0028] The transfer component 21 can be a linear module or other driving device, and the pitch-changing drive component 221 can be a telescopic cylinder, telescopic motor, or other driving device. The positioning seat 222 is adapted to the structure of the workpiece 200 and is used to support the workpiece 200. The number of positioning seats 222 is the same as the number of material loading slots 1121, and can be two, three, four, etc. The specific number depends on actual needs and is not limited here. It can be understood that before flipping the workpiece 200, the transfer component 21 drives the pitch-changing component 22 to move towards the flipping component 11, so that the multiple positioning seats 222 correspond to the flipped component 112. At this time, the pitch-changing drive component 221 drives the multiple positioning seats 222 to change pitch, so that the multiple positioning seats 222 correspond one-to-one with the multiple material loading slots 1121. Then, the blocking component 12 releases the workpiece 200, and the workpiece 200 falls from the material loading slot 1121 onto the corresponding positioning seat 222. It can be understood that the pitch-changing component 22 can increase or decrease the distance between the multiple workpieces 200, which can be set according to actual operational needs. In this embodiment, the pitch-changing component 22 is used to increase the spacing between the multiple workpieces 200. Of course, this is not a limitation of the embodiments of this application.

[0029] The positioning mechanism 30 includes a lifting drive 31, a first positioning component 32, and a second positioning component 33. The lifting drive 31 is arranged adjacent to the transfer pitch mechanism 20 along a first direction. The first positioning component 32 and the second positioning component 33 are both connected to the lifting drive 31. The lifting drive 31 drives the first positioning component 32 and the second positioning component 33 to move along a third direction to move closer to or away from the positioning seat 222. The first positioning component 32 is configured to position the workpiece 200 along the first direction, and the second positioning component 33 is configured to position the workpiece 200 along a second direction.

[0030] The lifting drive component 31 can be a lifting cylinder, etc. It is understood that the first positioning component 32 and the second positioning component 33 are mounted above the end of the transfer component 21 away from the flipping component 11. After the pitch-changing component 22 receives the workpiece 200, the transfer component 21 drives the pitch-changing component 22 to move below the first positioning component 32 and the second positioning component 33. Simultaneously, the pitch-changing drive component 221 drives multiple positioning seats 222 to move away from each other, increasing the distance between the multiple workpieces 200. Then, the lifting drive component 31 drives the first positioning component 32 and the second positioning component 33 to move towards the positioning seat 222. The first positioning component 32 positions the workpiece 200 along a first direction, and the second positioning component 33 positions the workpiece 200 along a second direction, thus completing the precise positioning of the workpiece 200. It is understood that after positioning, the first positioning component 32 and the second positioning component 33 release the workpiece 200, and the lifting drive component 31 drives the first positioning component 32 and the second positioning component 33 away from the positioning seat 222 along a third direction, so that an external material handling device (not shown) can pick up the material.

[0031] The flipping and positioning device 100 provided in this application embodiment, by setting a flipping mechanism 10, wherein the flipping member 112 can carry multiple workpieces 200, the stop assembly 12 can stop or release the workpieces 200, and the flipping drive member 111 drives the flipping member 112 to rotate around a first direction, thereby realizing the automatic flipping of the workpieces 200. By releasing the workpieces 200 through the stop assembly 12, the workpieces 200 can fall smoothly into the positioning seats 222 of the transfer and pitch-changing mechanism 20. The transfer component 21 of the transfer and pitch-changing mechanism 20 can drive the pitch-changing component 22 to move along a second direction to below the positioning mechanism 30, and at the same time, the pitch-changing drive member 221 can drive multiple positioning seats 222 to move closer or further away from each other along the first direction, thereby adjusting the spacing between the workpieces 200. The lifting drive member 31 of the positioning mechanism 30 drives the first positioning component 32 and the second positioning component 33 to move along a third direction. By positioning the workpieces 200 along the first direction through the first positioning component 32 and the second positioning component 33 along the second direction, the precise positioning of the workpieces 200 is achieved. The flipping and positioning device 100 provided in this application embodiment can automatically flip the workpiece 200, adjust the spacing between the workpieces 200, and accurately position the workpiece 200, effectively reducing labor intensity, improving work efficiency, and reducing the risk of collision damage to the workpiece 200.

[0032] In some embodiments, see Figure 1 and Figure 2 The material blocking assembly 12 includes a material blocking drive 121 and a material blocking member 122 connected to the material blocking drive 121. The material blocking drive 121 is connected to the flipping member 112. The material blocking member 122 is disposed on the side of the flipping member 112 where the material loading groove 1121 is opened. The material blocking member 122 is provided with a plurality of material blocking protrusions 1221 corresponding to the material loading groove 1121. The material blocking drive 121 is used to drive the material blocking member 122 to move along a first direction so that the material blocking protrusions 1221 move away from or close to the corresponding material loading groove 1121.

[0033] The material stop drive component 121 can be a telescopic cylinder, etc., the material stop component 122 can be a plate-like structure, and the material stop protrusion 1221 can be a sheet-like structure. The number of material stop protrusions 1221 can be the same as the number of material loading grooves 1121, such as two, three, four, etc., in which case the material stop protrusions 1221 correspond one-to-one with the material loading grooves 1121; the number of material stop protrusions 1221 can also be twice the number of material loading grooves 1121, such as four, six, eight, etc., in which case every two material stop protrusions 1221 correspond to one material loading groove 1121, so that two material stop protrusions 1221 can stop both ends of the workpiece 200. When it is necessary to place the workpiece 200 into the loading groove 1121, the blocking drive 121 drives the blocking member 122 to move along the first direction, so that the blocking protrusion 1221 is misaligned with the corresponding loading groove 1121, which facilitates the release of the workpiece. After the workpiece is released, the blocking drive 121 drives the blocking member 122 to move to the corresponding loading groove 1121, thereby stopping the workpiece 200 and preventing the workpiece 200 from slipping during the flipping process. When it is necessary to move the workpiece 200 to the positioning seat 222, the blocking drive 121 drives the blocking member 122 to move, thereby making the blocking protrusion 1221 misaligned with the corresponding loading groove 1121, and the workpiece 200 falls from the loading groove 1121 onto the positioning seat 222.

[0034] In some embodiments, see Figure 1 and Figure 2 The flipping assembly 11 also includes multiple sensors 113, each connected to the flipping member 112 and corresponding to one of the multiple material loading slots 1121. The sensors 113 are used to sense the workpiece 200 in the material loading slots 1121. The sensors 113 can be proximity switches, infrared sensors, etc., and are used to detect whether a workpiece 200 is placed in the material loading slot 1121. The number of sensors 113 is consistent with the number of material loading slots 1121; there can be two, three, four, etc., depending on actual needs, and this is not limited here. The sensors 113 can be directly installed on the side wall of the material loading slot 1121, or multiple through holes communicating with the material loading slots 1121 can be opened on the flipping member 112, with the sensors 113 installed on the side of the flipping plate away from the material loading slots 1121 and corresponding to the through holes.

[0035] In some embodiments, see Figure 1 and Figure 2The flipping assembly 11 also includes two stops 114, which are disposed on both sides of the flipping drive 111 along the second direction and corresponding to the flipping component 112. The stops 114 are used to stop and buffer the flipping component 112. By providing stops 114 on both sides of the flipping drive 111, damage to the flipping component 112 due to excessive movement can be prevented. The stopping function of the stops 114 can provide protection when the flipping component 112 moves abnormally, avoiding operational accidents caused by accidental impacts and improving safety. In this embodiment, the stops 114 can be buffers, with elastic structures such as springs inside, which can buffer when in contact with the flipping component 112, effectively absorbing the impact force of the flipping component 112 during movement, reducing equipment vibration, and improving operational stability.

[0036] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The transfer assembly 21 includes a transfer drive 211 and a transfer seat 212 connected to the transfer drive 211. The transfer drive 211 is disposed between the flipping assembly 11 and the positioning mechanism 30. The transfer seat 212 is configured to carry the pitch-changing drive 221 and multiple positioning seats 222. The transfer drive 211 drives the transfer seat 212 to move along a second direction, so that the transfer seat 212 moves the multiple positioning seats 222 closer to the flipping assembly 11 or below the first positioning assembly 32 and the second positioning assembly 33. The transfer drive 211 can be a linear module, etc., and the transfer seat 212 can be a plate-like structure. Through the cooperation of the transfer drive 211 and the transfer seat 212, the transfer assembly 21 can precisely control the movement of the pitch-changing assembly 22, ensuring the positional accuracy of the workpiece 200 during the transfer process.

[0037] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The pitch-changing assembly 22 also includes a slide rail 223, multiple sliders 224 and multiple connecting rods 225. The slide rail 223 is disposed on the transfer seat 212 and extends along the first direction. The multiple sliders 224 are all connected to the slide rail 223 and are correspondingly connected to the multiple positioning seats 222. The multiple connecting rods 225 are movably connected to two adjacent sliders 224 respectively. Each connecting rod 225 has a stop part 2251 at both ends.

[0038] The variable pitch drive 221 is fixedly connected to one of the multiple positioning seats 222 located at one edge. The slider 224 connected to the positioning seat 222 located at the other edge is fixedly connected to the slide rail 223. The remaining sliders 224 are slidably connected to the slide rail 223. The variable pitch drive 221 drives the connected positioning seats 222 to move closer to or further away from the adjacent positioning seats 222 to reduce or increase the distance between the multiple positioning seats 222. When the variable pitch drive 221 drives the positioning seats 222 to move away from each other, the stop part 2251 of the connecting rod 225 stops the slider 224 to limit the distance between two adjacent sliders 224.

[0039] In this embodiment, two slide rails 223 can be provided, respectively located at both ends of the positioning seat 222 along the second direction. The number of sliders 224 is twice the number of positioning seats 222, and can be four, six, eight, etc. Both ends of the positioning seat 222 along the second direction are connected to the slide rails 223 through sliders 224. The number of connecting rods 225 can be two, four, six, etc., and adjacent slide rails 223 are connected through connecting rods 225. The two ends of the connecting rods 225 are respectively inserted into the two adjacent sliders 224. When the two adjacent sliders 224 approach each other, the connecting rods 225 are inserted into the two sliders 224. When the two adjacent sliders 224 move away from each other, the stop portions 2251 at both ends of the connecting rods 225 stop the two sliders 224, thereby limiting the distance between the sliders 224 and thus limiting the distance between the two adjacent positioning seats 222 and the workpiece 200 on the positioning seats 222. Through the cooperation of slide rail 223, slider 224 and connecting rod 225, the pitch variable assembly 22 can realize the precise movement of multiple positioning seats 222 along the first direction, thereby accurately adjusting the distance between workpieces 200.

[0040] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The positioning seat 222 is provided with a positioning groove 2221, the structure of which is adapted to the structure of the workpiece 200, and the side wall of the positioning groove 2221 is provided with multiple clearance openings 2222. The positioning groove 2221, adapted to the structure of the workpiece 200, improves the stability of the positioning seat 222's support for the workpiece 200 during the movement of the transfer assembly 21 and the pitch-changing assembly 22, and also facilitates the precise positioning of the workpiece 200 in the positioning groove 2221 by the first positioning assembly 32 and the second positioning assembly 33. The multiple clearance openings 2222 on the side wall of the positioning groove 2221, while not affecting the support and positioning of the workpiece 200 by the positioning groove 2221, also avoid excessive constraint on the workpiece 200, reducing the risk of damage to the workpiece 200 during the positioning process.

[0041] In some embodiments, see Figure 1 , Figure 2 and Figure 4 The first positioning component 32 includes a pushing drive 321 and a pushing member 322. The pushing drive 321 is connected to the lifting drive 31, and the pushing member 322 is connected to the pushing drive 321 and mounted above the transfer component 21. The pushing member 322 has multiple pushing parts 3221 on the side facing the transfer component 21. The multiple pushing parts 3221 are corresponding to multiple positioning seats 222 one by one, and each pushing part 3221 is corresponding to the clearance opening 2222 of the corresponding positioning seat 222. The pushing drive 321 is used to drive the pushing member 322 to move in a first direction so that the pushing part 3221 pushes the workpiece 200 to the side wall of the positioning seat 222, thereby positioning the workpiece 200 in the first direction.

[0042] The pushing drive 321 can be a telescopic cylinder, a pen-shaped cylinder, etc., and the pushing part 3221 can be an L-shaped structure, both connected to the main body of the pushing member 322. The number of pushing parts 3221 can be two, four, six, etc., consistent with the number of positioning seats 222. It can be understood that the pushing part 3221 corresponds to the side of the workpiece 200 on the positioning seat 222 along the first direction. When positioning the workpiece 200, the pushing drive 321 drives the pushing part 322 to move along the first direction, so that the pushing part 3221 moves towards the corresponding workpiece 200, thereby pushing the workpiece 200 against the side wall of the positioning groove 2221, thus positioning the workpiece 200 in the first direction. In this embodiment, two first positioning components 32 can be provided, with the pushing parts 322 in the two first positioning components 32 corresponding to the two ends of the workpiece 200 respectively. The two first positioning components 32 move synchronously and simultaneously push the two ends of the workpiece 200, thereby improving the accuracy of positioning the workpiece 200.

[0043] In some embodiments, see Figure 1 , Figure 2 and Figure 4 The second positioning component 33 includes a clamping drive 331 and two clamping members 332. The clamping drive 331 is connected to the lifting drive 31. The two clamping members 332 are both connected to the clamping drive 331 and mounted above the transfer component 21. Each clamping member 332 has multiple clamping parts 3321 on the side facing the transfer component 21. The multiple clamping parts 3321 are corresponding to multiple positioning seats 222. The clamping parts 3321 on the two clamping members 332 correspond to the two ends of the positioning seats 222 along the second direction. The clamping drive 331 is used to drive the two clamping members 332 to move closer or further away from each other to clamp or release the workpiece 200, and to position the workpiece 200 in the second direction when clamping the workpiece 200.

[0044] The clamping drive 331 can center a cylinder, etc., and the clamping part 3321 can be a plate-like structure. The number of clamping parts 3321 on each clamping member 332 corresponds to the number of positioning seats 222, and their positions correspond to the positions of the positioning seats 222 after the pitch change. When the second positioning assembly 33 positions the workpiece 200, the clamping drive 331 drives the two clamping members 332 to move closer to each other, and the clamping parts 3321 on the two clamping members 332 simultaneously push against the workpiece 200, thereby centering the workpiece 200 in the second direction.

[0045] In some embodiments, see Figure 1 , Figure 2 and Figure 4 The clamping member 332 has multiple support portions 3322, each corresponding to a plurality of pushing portions 3221. The pushing portions 3221 are slidably disposed on the upper side of their respective support portions 3322, so that the support portions 3322 support the pushing portions 3221. The cooperation between the support portions 3322 and the pushing portions 3221 on the clamping member 332 enables the first positioning component 32 and the second positioning component 33 to work together, further optimizing the positioning accuracy and stability of the workpiece 200. The design of the support portions 3322 supporting the pushing portions 3221 reduces the need for additional support structures and lowers manufacturing costs.

[0046] The working process of the flipping positioning device 100 provided in this embodiment is roughly as follows:

[0047] First, the workpiece 200 is placed in the loading groove 1121 of the flipping component 112. The blocking component 122 of the blocking assembly 12, under the action of the blocking drive component 121, stops the workpiece 200 within the loading groove 1121, ensuring that the workpiece 200 is in a stable state before flipping. The flipping drive component 111 drives the flipping component 112 to rotate around a first direction, realizing the flipping of the workpiece 200. During the flipping process, the stopper 114 provides buffer protection to prevent damage to the flipping component 112 due to excessive movement.

[0048] After the flipping is completed, the stop assembly 12 releases the workpiece 200, and the workpiece 200 falls into the positioning seat 222 of the transfer and pitch-changing mechanism 20. The transfer drive 211 of the transfer assembly 21 drives the transfer seat 212 to move along the second direction, transferring the workpiece 200 below the positioning mechanism 30. At the same time, the pitch-changing drive 221 drives the multiple positioning seats 222 to move away from each other, so as to adjust the spacing between the workpieces 200.

[0049] The lifting drive 31 of the positioning mechanism 30 drives the first positioning component 32 and the second positioning component 33 to approach the workpiece 200 along a third direction. Under the action of the pushing drive 321, the pushing member 322 of the first positioning component 32 pushes the workpiece 200 along the first direction to the side wall of the positioning seat 222 through the pushing part 3221, thereby achieving the positioning of the workpiece 200 in the first direction. Under the action of the clamping drive 331, the clamping member 332 of the second positioning component 33 clamps and fixes the workpiece 200 along the second direction through the clamping part 3321, thereby completing the positioning of the workpiece 200 in the second direction.

[0050] After positioning is completed, the pushing drive 321 drives the pushing component 322 away from the workpiece 200, the clamping drive 331 drives the two clamping components 332 away from the workpiece 200, and the lifting drive 31 drives the first positioning component 32 and the second positioning component 33 away from the workpiece 200, so as to facilitate material handling by the external material handling device.
