In this embodiment, the at least one self-rotation driving group 20 includes one of the self-rotating driving groups 20, the self-rotating driving group 20 is arranged on the base 11 and has a predetermined distance from the rotating shaft, and the turntable 12 can rotate to make one of the The position of the grinding barrel 13 corresponds to the rotation driving group 20 and can be driven and rotated by the rotation driving group 20. In this way, the number of the rotation driving group 20 can be reduced, and the rotation driving group 20 does not need to rotate together with the turntable 12. The weight load of the turntable 12 can be reduced. In detail, the turntable 12 may include a base plate 121 and a driving mechanism 122 , a plurality of openings 1211 are formed on the surface of the base plate 121 around the rotating shaft, and the grinding barrels 13 are respectively disposed on the openings 1211 for shielding The openings 1211, the rotation driving group 20 can be combined with the grinding barrels 13 through the openings 1211, the driving mechanism 122 is connected with the base plate 121 to drive the base plate 121 to rotate around the shaft, for example, the The driving mechanism 122 may include a rotary motor 1221 and a transmission member 1222 connected to the rotary motor 1221 and driven by the rotary motor 1221 to rotate. A driven chain 1212 is provided at the bottom peripheral edge of the base plate 121, and the transmission member 1222 is engaged with the driven member 1222. In the chain 1212, when the rotating motor 1221 drives the transmission member 1222 to rotate, the driven chain 1212 drives the base plate 121 to rotate around the rotating shaft. However, the actual structure of the driving mechanism is not limited to this.

In addition, in order to position the turntable 12 to prevent it from rotating during processing, the present invention may further include at least one positioning element 30 , the at least one positioning element 30 is mounted on the base 11 so as to be movable up and down, and the turntable 12 is provided with at least one positioning element 30 . A positioning hole 1213, the at least one positioning element 30 is selectively raised to be inserted into the at least one positioning hole 1213 to prevent the turntable 12 from rotating. Preferably, the at least one positioning element 30 is connected to the rotation drive group 20. When After the at least one positioning element 30 is raised and inserted into the at least one positioning hole 1213, the side drives the autorotation driving group 20 to the driving position; when the autorotation driving group 20 drops to the initial position, the side drives the at least one positioning element 30 descend to disengage from the at least one positioning hole 1213 .

Regarding the actual structure of the first connection structure and the second connection structure, the first connection structure of each grinding barrel 13 may include at least one insert groove 1321 , and the second connection structure of the rotation driving group 20 may include at least one convex The inserting block 21, the at least one inserting groove 1321 and the at least one inserting block 21 are respectively a predetermined distance away from the rotation axis (in this embodiment, there are a plurality of the inserting grooves 1321 and a plurality of the inserting blocks 21, the The inserting grooves 1231 are arranged at intervals around the rotation axis, and the inserting blocks 21 are also arranged at intervals around the rotating axis). When the rotation driving group 20 is located at the driving position, the at least one inserting block 21 is inserted into the at least one inserting groove 1321 , so that the rotation drive group 20 is connected with the grinding barrel 13 in a non-rotatable manner, and can drive the grinding barrel 13 to rotate around the rotation axis; more specifically, each grinding barrel 13 includes a barrel 131 and a piece of 132 , the sheet body 132 is fixed on the bottom of the barrel body 131 . However, other connection structures can also be used. To be more extreme, for example, the first connection structure and the second connection structure can be made of materials with extremely high friction force, respectively, and the grinding barrel is driven to rotate by the huge surface friction force.

Regarding the first limiting structure and the second limiting structure, in this embodiment, the sheet body 132 has two side edges 1322 opposite to each other and parallel to each other, and the two side edges 1322 form the second limiting structure, Each of the first limiting structures includes two protruding strips 1214 that are spaced apart and arranged in parallel. A positioning space is enclosed between the two protruding strips 1214 . The distances correspond to each other, so that the sheet body 132 can be embedded in the positioning space with the two side edges 1322 corresponding to the two protruding strips 1214; The front baffle ridge 1215 is located between the two ridges 1214 and is perpendicular to the two ridges 1214 and is disposed on one side of the two ridges 1214 close to the center of the turntable 12, so that the positioning space is formed by the two ridges 1214 and the two ridges 1214. The sheet body 132 further includes a front edge 1323 surrounded by the front baffle ridge 1215, the front edge 1323 is perpendicular to the two side edges 1322 and located between the two side edges 1322, and the front edge 1323 is used to abut the front baffle ridge. 1215, thus, when the grinding barrel 13 is set in the positioning space and its front end abuts against the front baffle ridge 1215, it means that the grinding barrel 13 is positioned and oriented correctly, so as to facilitate the ascent and combination of the rotation drive group 20 .

Based on the above, since the first connection structure and the second connection structure may not be fully embedded before the rotation driving group 20 moves to the driving position, even if the connection is completed, the first limiting structure may not yet be connected with the second connection structure. The second limiting structure is staggered, so that the rotation driving group 20 cannot drive the grinding barrel 13 to rotate. Therefore, whether the position of the rotation driving group 20 is raised to a high enough position will be an important part of whether the automatic operation can be carried out smoothly. In this regard, the present invention uses the second detector 42 to detect the height detection portion 44 of the rotation driving group 20, and only when the second detector 42 detects the height detection portion 44, it means The self-rotation driving group 20 has been raised to a sufficient height to start to drive the grinding barrel 13 to rotate; on the contrary, if the turntable 12 is to be rotated to replace a different grinding barrel 13, it must be ensured that the self-rotating driving group 20 has been separated from the grinding Therefore, the present invention uses the first detector 41 to detect the height detection part 44 to confirm that the grinding barrel 13 has been separated from the rotation drive group 20 and the turntable 12 is rotated; To be correctly inserted into the inserting grooves 1321, the grinding barrel 13 also needs to be rotated to a specific angle. Therefore, before descending to the initial position, the rotation driving group 20 uses its angle detecting portion 45 for the third detector. 43 for detection (for example, the angle detection part 45 can be a groove 451 on one side of a detection sheet, when the groove 451 corresponds to the third detector 43, the third detector 43 detects the angle detection part 45), and rotates the rotation driving group 20 until the angle detection part 45 is aligned with the third detector 43 (preferably, when the rotation driving group 20 is at the driving position and the When the third detector 43 does not detect the angle detection part 45, the rotation driving group 20 cannot be lowered to the initial position to ensure smooth operation), so as to ensure that the angle of the grinding barrel 13 is correct. When the group 20 is lowered, the inserts 21 can be inserted into the insert grooves 1321 correctly, that is to say, the first limiting structure and the second limiting structure are also fitted in correspondence with each other, so that the grinding barrel 13 can is positioned on the turntable 12 .

Specifically, the self-rotation driving group 20 may include a main body 22 , a lifting shaft 23 and a self-rotating mechanism 24 , the main body 22 is disposed on the base 11 , the lifting shaft 23 can be raised and lowered through the main body 22 , the The rotation mechanism 24 is provided at the lower end of the lifting shaft 23 to drive the lifting shaft 23 to rotate around the rotation shaft; in this embodiment, a piston chamber 221 is formed inside the main body 22 , and a piston 231 is arranged outside the lifting shaft 23 . The piston 231 is slidably installed in the piston chamber 221 to divide the piston chamber 221 into an upper piston chamber and a lower piston chamber. The upper piston chamber and the lower piston chamber are respectively connected to a gas source or a liquid source. Or hydraulic drive makes the piston 231 slide up and down in the piston chamber 221 to drive the lift shaft 23 to rise and fall, which is beneficial to the control and arrangement of the automatic process; A rotating shaft 242, a transmission wheel 243, a transmission belt 244 and a driven pulley 245, the rotating shaft 242 is set on the rotating motor 241 and is driven to rotate by it, the transmission wheel 243 is set on the rotating shaft 242 and is synchronized with it Rotating, the driven wheel 245 is sleeved outside the lift shaft 23 and rotates synchronously with it, the transmission belt 244 is sleeved outside the transmission wheel 243 and the driven wheel 245, so that the driven wheel 245 is driven by the transmission wheel 243. Rotation, however, the structure is not limited to this.

In actual use, first of all, in the general situation that no operation is performed, as shown in FIG. 6 and FIG. 7 , the rotation driving group 20 is located at a lower initial position, and the first positioning structure and the second positioning structure are separated from each other. Do not interfere with each other. At this time, the grinding barrel 13 is not driven by the rotation drive group 20 to rotate, and due to the mutual interference between the first limiting structure and the second limiting structure, the grinding barrel 13 is limited to a certain angle between the turntable 12. At a specific position, at this time, the turntable 12 can be rotated to replace the grinding barrel 13 or the cleaning barrel required for the grinding operation, without being disturbed by the rotation drive group 20, wherein the height of the height detection part 44 is exactly corresponding to the first detection The detector 41 can be used by the system to know the position and state of the autorotation drive group to confirm whether the turntable can be rotated.

When the grinding operation is to be performed, as shown in FIG. 8 and FIG. 9 , the self-rotating driving group 20 can be driven to rise to the driving position. During this process, the first positioning structure and the second positioning structure are combined with each other to make the grinding barrel 13 is lifted by the rotation driving group 20, so that the first limiting structure and the second limiting structure are staggered and not interfered with each other. At this time, the rotation of the rotation driving group 20 can drive the grinding barrel 13 to rotate together to facilitate the grinding process. The height of the height detector 44 corresponds to the second detector 42 , and the system can know the position and state of the rotation driving group 20 to confirm whether the rotation driving group 20 can be started to rotate.

It should be noted that, since the first limiting structure and the second limiting structure are fitted with each other in a specific direction and angle, before lowering the grinding barrel 13, it is necessary to confirm the relative relationship between the grinding barrel 13 and the turntable 12. Whether the angle is correct, for this, the angle detection part 45 and the third detector 43 can be used to rotate the rotation drive group 20 until the angle detection part 45 is aligned with the third detector 43 for detection, namely It means that the direction and angle of the grinding barrel 13 are correct, so that the first limiting structure and the second limiting structure can be correctly combined with each other.

Among them, the first limiting structure of the present invention adopts the convex strip 1214, and the second limiting structure adopts the sheet body 132 with a rectangular outline, which is not only easy to manufacture and assemble, but also ensures that the grinding barrel can enter the positioning space horizontally, reducing the need for users to change The burden of barrel time.

Thereby, the barrel changing device and the lifting device of the automatic processing machine of the present invention can quickly replace the grinding barrel without manual handling, and only one set of the self-rotating drive group with the lifting clutch function needs to be set up, which greatly reduces the weight burden of the turntable and the machine. The volume of the table and the detection group are used to ensure that the height and direction of the grinding barrel are correct, which is very beneficial to the progress of the fully automated process, which is expected by the relevant processing industry. The scope of this patent shall be subject to the scope of the patent application described later.
