Specifically, when the device is used, the servo motor 111 is started to synchronously drive the driving wheel 1121, the transmission belt 1122 and the driven wheel 1123, so that the cam divider 113 can drive the rotating disc 12 to rotate according to a set angle each time; for example, in the present invention, eight magazine blocks 121 are provided on the rotary table 12, and the rotation angle of the rotary table 12 is 45 °.
It should be noted that the cam divider 113 is also called a cam indexer or an intermittent divider in engineering, and is a high-precision rotating device, and it belongs to the prior art, so the detailed description of the specific structure of the present invention is omitted.
Referring to fig. 2 to 6, considering that the workpieces P in the cassette block 121 corresponding to the carrier plate 22 are reduced along with the transfer of the conveying mechanism 3, the overall height of the stacked workpieces P is gradually reduced, so as to change the downward moving range of the conveying mechanism 3, so that the material taking position of the conveying mechanism 3 is changed each time, and further the moving stroke of the conveying mechanism 3 is increased, thereby requiring a long time to transfer the materials in the corresponding cassette block 121; in order to solve the problem, the present invention further comprises a lifting mechanism 4, wherein a plurality of box blocks 121 are respectively provided with a storage groove 1210 for stacking the workpieces P, and the top side of the box blocks 121 is provided with a material taking port 1211 communicated with the storage groove 1210 and the outside; the rotary disk 12 is further provided with a plurality of top holes 122, and the top holes 122 are communicated with the storage slots 1210 in the plurality of box blocks 121 in a one-to-one correspondence manner; the lifting mechanism 4 is disposed below the turntable 12, and when the supporting board 22 corresponds to any one of the box blocks 121 on the turntable 12, the output end of the lifting mechanism 4 can penetrate through the top hole 122 corresponding to the box block 121, and drive the workpiece P stacked in the storage slot 1210 of the box block 121 to move upward.
Specifically, when the workpiece P is stacked in the magazine block 121, the workpiece P located at the topmost side of the stack of workpieces P is placed in the material taking port 1211, and the workpiece P placed in the material taking port 1211 can be directly taken away by the conveying mechanism 3 and transferred to the positioning component 21 on the bearing plate 22;
when in use, the first driving part 11 drives the rotating disc 12 to rotate, so that the first box block 121 corresponds to the supporting plate 22, and the top hole 122 corresponding to the first box block 121 is aligned with the lifting mechanism 4; at this time, after the conveying mechanism 3 transfers the workpiece P located in the material taking port 1211 of the first box block 121, the lifting mechanism 4 is started, the output end of the lifting mechanism 4 penetrates through the aligned top hole 122 and extends into the material placing groove 1210 of the first box block 121 to abut against and drive the stack of the workpiece P to move upward by the height of one workpiece P, so that the workpiece P located at the topmost side of the stack of the workpiece P enters the material taking port 1211 at present, and the conveying mechanism 3 can directly transfer the workpiece P again;
after the workpieces P in the first cassette block 121 are taken out, the output end of the lifting mechanism 4 is controlled to be separated from the top hole 122 corresponding to the first cassette block 121, and then the rotary disc 12 is driven to rotate by the first driving part 11, so that the top hole 122 corresponding to the second cassette block 121 is aligned with the lifting mechanism 4, and the conveying mechanism 3 transfers the workpieces P in the second cassette block 121 on the premise that the material taking position is not changed; while the conveying mechanism 3 is operating, the worker can stack the workpieces P with the empty first cassette block 121;

Referring to fig. 2 to 6, the lifting mechanism 4 has various structures, and for easy understanding, in the present invention, the lifting mechanism 4 includes a fixing plate 41, a lead screw motor 42, a sliding seat 43 and a supporting rod 44; the fixed plate 41 is vertically arranged below the turntable 12, and the sliding seat 43 is slidably arranged on the fixed plate 41; the support rod 44 is arranged on the sliding seat 43 and serves as an output end of the lifting mechanism 4; the screw rod motor 42 is arranged on the fixing plate 41 and is in driving connection with the sliding seat 43 so as to drive the sliding seat 43 to move up and down; when the supporting board 22 corresponds to any one of the cassette blocks 121 on the turntable 12, the lead screw motor 42 drives the supporting rod 44 to penetrate through the top hole 122 corresponding to the cassette block 121, and drives the workpiece P stacked in the storage slot 1210 of the cassette block 121 to move upward.
Specifically, when the first cassette block 121 corresponds to the carrier plate 22, the conveying mechanism 3 is used to transfer the workpiece P located in the material taking port 1211 of the first cassette block 121, and then the lead screw motor 42 is started to drive the sliding base 43 and the supporting rod 44 to move upward by the height of one workpiece P, so that one end of the supporting rod 44 penetrates through the corresponding top hole 122 to the material placing groove 1210 of the first cassette block 121 and abuts against the workpiece P stack to move upward by the height of one workpiece P, thereby ensuring that the workpiece P located at the topmost side of the workpiece P stack is taken out of the material taking port 1211;
when the conveying mechanism 3 transfers the workpiece P in the material fetching port 1211 again, the screw rod motor 42 drives the slide carriage 43 to move up by the height of the workpiece P again; in this way, until all the workpieces P in the storage slot 1210 of the first box block 121 are taken out, the slide 43 is driven by the lead screw motor 42 to move downward and return to the original position, the turntable 12 is driven by the first driving part 11 to rotate, so that the second box block 121 corresponds to the bearing plate 22, and then the above operations are repeated.

Referring to fig. 2 to 6, based on the above description, the user can preset the lead screw motor 42 in advance by a program to ensure that the lead screw motor 42 drives the slide carriage 43 to move up a specific distance within a specific interval time, and the lead screw motor 42 can control the timing of the support rod 44 entering and leaving the storage slot 1210 by setting a sensor in addition to the preset program; for example, in the present invention, the lifting mechanism 4 further includes a first sensor 45, the first sensor 45 is installed on the support rod 44 and electrically connected to the lead screw motor 42, and the sensing end of the first sensor 45 is vertically upward designed to monitor whether there is a workpiece P in the corresponding object placing groove 1210 one by one.
Specifically, under the conventional condition, the supporting rod 44 is far away from the top hole 122, and when the first driving portion 11 drives the rotating disc 12 to rotate, so that the first cassette block 121 corresponds to the bearing plate 22, the first sensor 45 detects whether the workpiece P exists in the object placing groove 1210 of the first cassette block 121; if the sensing light of the first sensor 45 is not blocked, it is proved that no workpiece P exists in the storage tank 1210, the first sensor 45 will send out a warning to remind the user to supplement the material; generally, the first sensor 45 is connected to an external sound unit to send out an alarm;
if the sensing light of the first sensor 45 is shielded, it is proved that the workpiece P exists in the storage groove 1210, the first sensor 45 sends a signal to the lead screw motor 42 to control the lead screw motor 42 to operate and drive the support rod 44 to enter the storage groove 1210 and abut against the workpiece P; when the workpieces P in the first cassette block 121 are completely transferred, the sensing light of the first sensor 45 is not blocked, and then the first sensor 45 sends a signal to the lead screw motor 42 to control the lead screw motor 42 to operate and drive the support rod 44 to move down to be separated from the object placing slot 1210 and the top hole 122, so as to ensure that the turntable 12 can smoothly rotate. In summary, the design of the first sensor 45 can improve the automation degree of the feeding mechanism 1, and precisely control the time when the supporting rod 44 of the supporting rod 44 enters and leaves the storage tank 1210.
