In the present embodiment, as shown in fig. 3, the circulation power source 31 includes a motor provided at the bottom upward, and the position of the motor is provided on one side of the first arc segment 323. The output of motor is provided with first carousel, and first carousel is the structure that forms first arc section 323, and the position department of second arc section 324 is provided with the second carousel, and the second carousel is the structure that forms second arc section 32. The annular track 32 is selected to be a chain structure that mates with the first and second disks, i.e., the circumferential outer walls of the first and second disks can engage the inside of the annular track 32 to effect torque transfer. As shown in fig. 3, the bottom of the die holder 33 main body is connected with the annular track 32, and the top of the die holder 33 main body is divided into four sub-die holders, and the sub-die holders are used for clamping the tray part. The rotational speed of the motor determines the speed of movement of the circular track 32 and thus the speed of movement of the tray portion 2 on the die holder 33 between different preset positions.

In fig. 3, three tray portions 2 are disposed on a first straight line 321, three tray portions 2 are disposed on a second straight line 322, and a first arc 323 and a second arc 324 are disposed on each of the tray portions 2.

When the tray portion 2 moves to the fourth preset position 004, only the jig plate 21 is clamped on the die holder 33 at this time, and dust and dirt are accumulated on the surface of the jig plate 21 along with the increase of the circulation times because the jig plate 21 does not need to perform dust removal operation every time in the processing process of the raw materials. Therefore, the fourth preset position 004 is set, so that the jig plate 21 can be detached from the fourth preset position 004 and replaced by a clean jig plate 21, if necessary, automatically or manually. The fourth preset position 004 is arranged at a position which is convenient to operate, and can ensure the normal operation of the feeding and discharging system, so that the efficiency reduction and the cost increase caused by shutdown are avoided.

When the tray portion 2 moves to the fifth preset position 005, the positioning manipulator 72 accurately stacks the raw materials on the positioning platform 71 on the jig plate 21, and the corresponding third preset position 003 may include two positions, and the fifth preset position 005 also includes two positions, which is not described in detail.

When the tray portion 2 moves to the sixth preset position 006, the second grabbing component 44 of the dust removing component 4 grabs the clean cover plate 22 after dust removal, stacks the clean cover plate 22 on the jig plate 21 containing raw materials, and recirculates the clean cover plate to the first preset position 001.

The arrangement of the first preset position 001 to the sixth preset position 006 can be effectively matched with the shape setting of the annular track 32 of the circulating assembly 3, and the setting is more reasonable, so that the circulating process is smoother.

The first driving assembly 6123 in fig. 9 acts to drive the eight feeding chucks 6122 to rearrange in a straight line parallel form, and adjusts the interval between two adjacent feeding chucks 6122, so that the eight feeding chucks 6122 on the whole feeding chuck assembly 612 are divided into two groups of four, and each group is distributed and arranged according to the second arrangement position. After the adjustment, the feeding mechanical arm 611 acts to distribute and stack the raw materials in the two groups of feeding suction cups 6122 distributed according to the second arrangement position on the feeding suction cup assembly 612 on the first positioning platform 711 and the second positioning platform 712.

From this, the radius of movement of the loading arm 611 covers the plurality of Tray disks 8 in the loading frame 621 in the loading section 62, and covers the first positioning platform 711 and the second positioning platform 712. Meanwhile, in the embodiment, the first driving component 6123 is preferably an air cylinder, the structural strength of the first driving component 6123 is high, the control is easy, and the adjustment of the switching between the first arrangement position distribution and the second arrangement position distribution of the feeding sucker component 612 is realized by controlling the extension and retraction of the air cylinder according to the different positions of the air cylinder.

Since four living things distributed according to the second arrangement position are accommodated on the first positioning platform 711 and the second positioning platform 712, and eight second accommodating grooves 211 are provided in the jig plate 21 on the circulation assembly 3, and eight second accommodating grooves 211 are distributed according to the third arrangement position, it is also necessary to perform position change again on the raw materials in the first positioning platform 711 and the second positioning platform 712 so as to stack in the jig plate 21.

Because the processing precision of the jig plate 21 is higher, the subsequent process also needs to interact with the internal raw materials to process the raw materials into a finished product, so that the positioning precision requirement of the raw materials in the jig plate 21 is higher, correspondingly, the Tray 8 is only used for bearing the raw materials or the finished product, the positioning precision is lower, and the positioning precision requirement of the jig plate 21 can be met only by readjusting the position precision of eight raw materials under the action of the positioning component 7. Therefore, the positioning component 7 has reasonable arrangement position and ingenious structure, and can better ensure the normal movement of the feeding and discharging system; meanwhile, the positioning assemblies 7 are divided into two groups, and each group is used for controlling the position adjustment of four raw materials, so that the efficiency is higher and the speed is higher.
