[0027] This embodiment provides a flipping device, as Figures 1 - 4 shown, which includes a rotation driving mechanism 100 and a mounting base 200. The mounting base 200 includes a central portion 210 and an annular portion 220 surrounding the central portion 210. The annular portion 220 is circumferentially divided into a plurality of mounting segments 221. Each mounting segment 221 includes a mounting area 221a and a flipping area 221b in a direction away from the central portion 210; a flipping driving mechanism 300 is installed in each mounting area 221a, and a plurality of carrier seats 400 are rotatably connected in each flipping area 221b. The driving end of the flipping driving mechanism 300 is connected to the corresponding plurality of carrier seats 400 to drive the plurality of carrier seats 400 to flip synchronously; the end of the rotation driving mechanism 100 is connected to the central portion 210 to drive the mounting base 200 to rotate.

[0028] The flipping device provided in this embodiment is radially divided into two regions. Among them, the region at the central position serves as the central portion 210, and the other regions surrounding the central portion 210 serve as the annular portion 220. The annular portion 220 is further radially divided into an inner ring region including a plurality of mounting areas 221a and an outer ring region including a plurality of flipping areas 221b; the mounting area 221a and the flipping area 221b corresponding to each other radially form a mounting segment 221. Each mounting segment 221, the flipping driving mechanism 300 installed in the mounting area 221a of this mounting segment 221, and the plurality of carrier seats 400 installed in the flipping area 221b of this mounting segment 221 correspondingly serve as a flipping unit. Then, the flipping device includes a plurality of flipping units along the circumference of the mounting base 200, and the rotation driving mechanism 100 can drive the plurality of flipping units to rotate along the circumference of the mounting base 200.

[0029] In use, each carrier 400 carries a jig 10, and the jig 10 is equipped with a workpiece to be processed. The rotary drive mechanism 100 drives the mounting base 200 to rotate, so that one of the flipping units is rotated to the processing station as the target unit. In this target unit, the flipping drive mechanism 300 can drive a plurality of carriers 400 to carry the jig 10 and the workpiece to be processed to perform synchronous flipping to cooperate with the processing operation of the processing station for the workpiece to be processed, thereby realizing the synchronous processing operation of a plurality of workpieces to be processed in the target unit. After the processing of the workpiece to be processed in the target unit is completed, the rotary drive mechanism 100 can drive the mounting base 200 to rotate by a certain angle, so that the adjacent flipping unit is rotated to the processing station as the new target unit, thereby performing the synchronous processing operation on a plurality of workpieces to be processed in the new target unit. In this way, until the processing operations of all the workpieces to be processed carried by the flipping units are completed.

[0030] In the flipping device provided in this embodiment, on the one hand, in each flipping unit, the flipping drive mechanism 300 can drive a plurality of carriers 400 to carry the jig 10 and the workpiece to be processed to perform synchronous flipping, so as to realize the synchronous processing operation of a plurality of workpieces to be processed. At the same time, a plurality of flipping units are arranged along the circumferential direction of the mounting base 200, and the rotary drive mechanism 100 drives the plurality of flipping units to rotate to the processing station in sequence for processing operations, thereby further improving the processing efficiency of the workpiece to be processed and the functionality of the flipping device.

[0031] On the other hand, the mounting base 200 is radially divided into a central portion 210 and an annular portion 220, and the annular portion 220 is further radially divided into an inner ring area including a plurality of installation areas 221a and an outer ring area including a plurality of flipping areas 221b. Among them, the rotary drive mechanism 100 as the rotation power source is arranged in the central portion 210; a plurality of flipping drive mechanisms 300 as the flipping power source are arranged in the inner ring area and are circumferentially distributed in each installation area 221a; a plurality of carriers 400 as the flipping carriers are arranged in the outer ring area and are circumferentially distributed in each flipping area 221b. Thereby, the radial area and circumferential area of the mounting base 200 are reasonably distributed, the arrangement compactness of each mechanism and the carrier 400 is improved, the number of carriers 400 carried by the flipping device is increased, and the volume of the entire flipping device is reduced, correspondingly improving the use flexibility and adaptability of the flipping device. At the same time, a plurality of carriers 400 are located in the outermost outer ring area of the mounting base 200, the operation during processing is more convenient and less affected by interference, making the use flexibility and adaptability of the flipping device higher. In addition, the flipping drive mechanism 300 and the rotary drive mechanism 100 are located in the inner ring area and central area closer to the inside of the mounting base 200, and the probability of being damaged by interference and collision during processing is smaller, which can ensure the normal use of the flipping device.

[0032] Optionally, in this embodiment, as Figure 1 and Figure 3As shown, both the rotation drive mechanism 100 and the flipping drive mechanism 300 are located on the back side of the mounting base 200. An opening 222 is provided in the area of the flipping area 221b corresponding to the carrier 400. The opposite sides of the mounting base 200 are respectively the operation side and the back side. Among them, the bearing surface of the carrier 400 is located on the operation side; during use, when the flipping unit rotates to the processing station, the operation side of the mounting base 200 faces the processing device, and the processing device can perform processing operations on the workpiece to be processed on the operation side; in this embodiment, both the rotation drive mechanism 100 and the flipping drive mechanism 300 are arranged on the back side of the mounting base 200, and the carrier 400 can be exposed to the operation side of the mounting base 200 through the opening 222. Specifically, the workpiece to be processed can be directly located on the operation side of the mounting base 200, or although the workpiece to be processed is located on the back side of the mounting base 200 but can be exposed through the opening 222. Correspondingly, during use, the processing device can perform processing operations on the workpiece to be processed extending out of the operation side, or perform processing operations on the workpiece to be processed located on the back side through the opening 222; at the same time, the rotation drive mechanism 100 and the flipping drive mechanism 300 are shielded by the mounting base 200 on its back side, and during the processing operation, it will not interfere with the operation of the processing device, and at the same time, it can also reduce the occurrence of being damaged by collision, thereby improving the use flexibility and adaptability of the flipping device and ensuring the service life of the flipping device.

[0033] In this embodiment, as Figure 1 、 Figure 2 and Figure 4As shown in the figure, a plurality of pivot seats 310 are provided in the flipping area 221b. Each group of pivot seats 310 includes a first seat body 311, a second seat body 312, and a rotating shaft 320 rotatably connected between the two. The rotating shaft 320 extends in the direction towards the central part 210, and the extending end is fixedly connected to the driving end of the flipping driving mechanism 300; correspondingly, a plurality of carrier seats 400 are fixedly connected to the plurality of rotating shafts 320 one by one. The installation area 221a, the flipping area 221b, the flipping driving mechanism 300 provided in the installation area 221a, and the plurality of carrier seats 400 provided in the flipping area 221b belonging to the same flipping unit correspond to each other. In each flipping area 221b, the plurality of rotating shafts 320 all extend along the radial direction of the mounting seat 200 and are arranged at intervals along the circumferential direction of the mounting seat 200. Both ends of the rotating shaft 320 in the length direction are respectively supported by the first seat body 311 and the second seat body 312, and one end of the rotating shaft 320 facing the central part 210 extends out of the first seat body 311 and is connected to the driving end of the flipping driving mechanism 300; during use, the flipping driving mechanism 300 can drive the plurality of rotating shafts 320 to rotate synchronously, and the plurality of rotating shafts 320 drive the respective connected carrier seats 400 to rotate synchronously, so as to realize the synchronous flipping drive of the plurality of carrier seats 400; wherein, during the flipping process, both ends of the rotating shaft 320 are respectively supported by the first seat body 311 and the second seat body 312, and the rotational stability is relatively high, which can ensure the stability of driving the carrier seat 400 to flip, and at the same time reduce the load of the flipping driving mechanism 300 for carrying the carrier seat 400.

[0034] Specifically, in this embodiment, as Figure 1 and Figure 2 shown, the flipping driving mechanism 300 includes a linear driving member 330 provided in the installation area 221a. A rack 340 is fixedly connected to the end of the linear driving member 330 for driving the rack to reciprocate along its length direction; correspondingly, gears 350 are fixedly connected to the extending ends of the plurality of rotating shafts 320, and the plurality of gears 350 are all meshed with the rack 340. During use, the linear driving member 330 drives the rack 340 to move along its length direction, thereby driving the plurality of gears 350 meshed with it to rotate synchronously, and correspondingly driving the plurality of rotating shafts 320 and their connected carrier seats 400 to flip synchronously.

[0035] Preferably, a guide rail consistent with the length direction of the rack 340 is provided in the installation area 221a. A slider 341 is fixedly connected to the rack 340, and the slider 341 is slidably clamped on the guide rail. During the process of the linear driving member 330 driving the rack 340 to move, the guide rail can play a role of linear guiding for the movement of the slider 341 and the rack 340, thereby improving the movement accuracy of the rack 340, and correspondingly ensuring the meshing of the rack 340 with the plurality of gears 350 and the synchronous driving of the plurality of gears 350.

[0036] Specifically, the linear driving member 330 can be selected from a push rod motor, a cylinder, a hydraulic cylinder, etc.

[0037] In this embodiment, as Figure 4 shown, a first limiting member 360 and a second limiting member 370 for abutting and limiting against the rack 340 can be arranged in the installation area 221a. The carrier 400 has a first flipping position corresponding to the first limiting member 360 and a second flipping position corresponding to the second limiting member 370. The movement stroke of the rack 340 along its length direction determines the rotation angle of the gear 350, and correspondingly determines the flipping angle of the carrier 400. According to the first flipping position and the second flipping position required by the carrier 400, the positions of the first limiting member 360 and the second limiting member 370 relative to the rack 340 are determined. Then, during the process that the rack 340 moves along its length direction towards the first limiting member 360, the rotating shaft 320 drives the carrier 400 to flip in the first direction. When the rack 340 abuts against the first limiting member 360, the rack 340 cannot move further. At this time, the carrier 400 flips to the first flipping position; similarly, during the process that the rack 340 moves along its length direction away from the first limiting member 360 and towards the second limiting member 370, the rotating shaft 320 drives the carrier 400 to flip in the second direction opposite to the first direction. When the rack 340 abuts against the second limiting member 370, the rack 340 cannot move further. At this time, the carrier 400 flips to the second flipping position, thereby realizing the limiting of the flipping of the carrier 400, improving the flipping accuracy of the flipping driving mechanism 300 for the carrier 400, and reducing the requirement for the driving accuracy of the linear driving member 330.

[0038] In this embodiment, as Figure 1 , Figure 3 and Figure 4 shown, a limiting frame 380 is arranged in the flipping area 221b. The limiting frame 380 is fixedly provided with a third limiting member 381 and a fourth limiting member 382 for abutting and limiting against the carrier 400. Among them, when the carrier 400 abuts against the third limiting member 381, it is in the first flipping position, and when it abuts against the fourth limiting member 382, it is in the second flipping position. The linear driving member 330 drives the rack 340 to move, thereby driving the gear 350, the rotating shaft 320 and the carrier 400 to rotate synchronously in the first direction. When the carrier 400 abuts against the third limiting member 381, it cannot flip further, thereby stopping at the first flipping position; similarly, when the carrier 400 rotates in the second direction and abuts against the fourth limiting member 382 for limiting, it cannot flip further, thereby stopping at the second flipping position; then the third limiting member 381 can directly abut and limit the carrier 400, and cooperate with the first limiting member 360 to double-limit the first flipping position of the carrier 400; similarly, the fourth limiting member 382 can directly abut and limit the carrier 400, and cooperate with the second limiting member 370 to double-limit the second flipping position of the carrier 400, thereby further ensuring the position accuracy of the carrier 400 flipping to the first flipping position and the second flipping position.

[0039] Specifically, in this embodiment, as Figure 4 shown, the first limiting member 360 includes a fixed seat 361 fixedly arranged in the installation area 221a. The fixed seat 361 is located on one side of the rack 340 in the length direction and is provided with an elastic buffer member 362 and a limiting post 363 extending towards the rack 340. Moreover, the extending length of the elastic buffer member 362 towards the rack 340 is greater than that of the limiting post 363. The elastic buffer member 362 and the limiting post 363 are both extended along the length direction of the rack 340 at the part between the fixed seat 361 and the end of the rack 340, and the extending length of the elastic buffer member 362 is greater than that of the limiting post 363, so the distance between one end of the elastic buffer member 362 towards the rack 340 and the rack 340 is smaller; wherein, the limiting post 363 is a rigid member, and the elastic buffer member 362 can elastically deform along its length direction.

[0040] When the rack 340 moves towards the first limiting member 360 under the drive of the linear driving member 330, the end of the rack 340 first contacts the elastic buffer member 362 and exerts a squeezing effect on it. The elastic buffer member 362 is compressed and deformed by the squeezing, playing a role in buffering and decelerating the movement of the rack 340 until the rack 340 abuts against the limiting post 363 and the rack 340 stops moving, thereby realizing the limitation of the rack 340 and reducing the damage caused by the rigid collision between the rack 340 and the first limiting member 360 during the limiting process.

[0041] Similarly, the second limiting member 370, the third limiting member 381 and the fourth limiting member 382 can also adopt the structure of the above-mentioned first limiting member 360. Among them, the fixed seats 361 of the second limiting member 370 and the first limiting member 360 are located on both sides of the rack 340 in the length direction; the fixed seats 361 of the third limiting member 381 and the fourth limiting member 382 are both fixedly connected to the limiting frame 380, and the elastic buffer members 362 and the limiting posts 363 connected to different fixed seats 361 face the carrier 400 at different angles.

[0042] Specifically, when the carrier 400 rotates to be parallel to the mounting seat 200, it can be used as the first flipping position, and when the carrier 400 rotates to be perpendicular to the mounting seat 200, it can be used as the second flipping position.

[0043] In addition to adopting the above-mentioned cooperation form of the rack 340 and the gear 350, in some other embodiments, the flipping drive mechanism 300 can also adopt the cooperation form of a synchronous belt and a plurality of belt pulleys.

[0044] In this embodiment, as Figure 1 and Figure 3As shown in the figure, the rotary drive mechanism 100 may specifically adopt the following form: It includes a rotary drive member 110. A guide cylinder 113 is provided on the housing portion 111 of the rotary drive member 110, and the guide cylinder 113 surrounds the drive shaft 112 of the rotary drive member 110. The central portion 210 is provided with a guide hole 211 and multiple support arms 130 surrounding the guide hole 211. The guide hole 211 is rotatably sleeved on the guide cylinder 113. The end of the drive shaft 112 is fixedly connected with a connection frame 120, and the connection frame 120 is fixedly connected to one end of the multiple support arms 130 away from the central portion 210. During use, the rotary drive member 110 is fixed to the base or fixedly connected to the robotic arm, and the guide cylinder 113, the drive shaft 112, and the guide hole 211 are coaxially arranged. When it is necessary to rotate the mounting seat 200, the rotary drive member 110 drives the connection frame 120 to rotate through its drive shaft 112, and the connection frame 120 then drives the mounting seat 200 to rotate synchronously with it through the support arms 130. During the rotation process, the guide cylinder 113 guides and limits the guide hole 211, thereby improving the coaxiality between the mounting seat 200 during the rotation process and the drive shaft 112, correspondingly ensuring the rotation stability and position accuracy of the mounting seat 200, ensuring the precise cooperation between each flipping unit and the processing station, and reducing the large load on the drive shaft 112 directly connected to the mounting seat 200 to bear the mounting seat 200 and the easy bending deformation of the drive shaft 112 under the torque applied by the mounting seat 200, resulting in the situation that the mounting seat 200 shakes during the rotation process and cannot cooperate with the processing station.

[0045] Optionally, in this embodiment, a suction channel is provided inside the rotating shaft 320. The suction channel extends along the length direction of the rotating shaft 320 and penetrates through one end of the rotating shaft 320 away from the central portion 210 to form a communication port 321. A suction nozzle 510 is provided on the loading side of the carrier 400. The carrier 400 is provided with a communication channel, and the communication channel communicates between the suction nozzle 510 and the suction channel. The fixture 10 is provided with a through hole corresponding to the suction nozzle 510. When the fixture 10 is installed on the carrier 400, the suction nozzle 510 can adsorb and fix the workpiece to be processed carried on the fixture 10 through the through hole, thereby improving the stability of the fixture 10 carrying the workpiece to be processed. Specifically, during use, the communication port 321 is connected to the suction assembly through a communication pipeline. By providing a suction channel inside the rotating shaft 320 and a communication channel inside the carrier 400, the suction assembly can form a negative pressure at the suction nozzle 510 through the suction channel and the communication channel, thereby performing vacuum adsorption on the workpiece to be processed. Among them, during the synchronous flipping process of the carrier 400 and the rotating shaft 320, the communication channel and the suction channel provided inside the two flip synchronously with them, while the communication port 321 located at the outer end of the rotating shaft 320 only rotates circumferentially around its axis and does not displace, thereby ensuring the airtightness of the connection between the communication port 321 and the suction channel and reducing the occurrence of winding and breaking of the communication pipeline during the flipping process.

[0046] Specifically, as Figure 3As shown, the suction assembly may select the vacuum generating mechanism 520. There are multiple groups of the vacuum generating mechanism 520, and the multiple groups of the vacuum generating mechanism 520 are arranged at the central part 210 and correspond to the multiple flipping areas 221b one by one. Each group of the vacuum generating mechanism 520 includes multiple vacuum generators 521 stacked on top of each other. The multiple vacuum generators 521 in the same group are connected to the corresponding multiple communication ports 321 one by one; a cover is provided at the central part 210, and the multiple groups of the vacuum generating mechanism 520 are all covered inside the cover. By stacking multiple small-sized vacuum generators 521 at the central part 210 to form the vacuum generating mechanism 520, and connecting it to the communication ports 321 of the multiple rotating shafts 320 of a single flipping unit, the vacuum pumping operation of the suction nozzles 510 of each carrier 400 in the flipping unit can be realized. The structure is compact, and the vacuum generating mechanism 520 rotates synchronously with the mounting base 200, which can effectively reduce the occurrence of winding and breaking of the connecting pipelines during the rotation process.

[0047] Specifically, the housing part 111 of the rotation driving member 110 is located on the back side of the mounting base 200, and the driving shaft 112, the support arm 130, the connecting frame 120 and the vacuum generating mechanism 520 of the rotation driving member 110 are all located on the operation side of the mounting base 200. The cover is located on the operation side and covers the driving shaft 112, the support arm 130, the connecting frame 120 and the vacuum generating mechanism 520 inside it, so as to shield and protect them and reduce the occurrence of collision damage during the processing operation.
