[0049] In the above embodiment, specifically please refer to Figure 1The intermediate transport device comprises a vacant station, a feeding station, a decal station and a discharging station. The feeding station of the intermediate transport device is provided with a feeding conveyor 6, and the discharging station is provided with a discharging conveyor 7. The feeding conveyor 6 and the discharging conveyor 7 are used for conveying the enamel cups.

The arc-shaped lifting plate 2 can lift the vessel clamping mechanism 405 at the feeding station, so that the set of vessel clamping mechanisms 405 actively approaches the linkage frame 502, and then the clamp is “opened” to facilitate the subsequent clamping of the enamel cup. The vessel clamping mechanism 405 at the discharging station needs to be stable in position before discharging, so when the rotary material conveying mechanism 4 descends in height together with the lifting plate 104, the vessel clamping mechanism 405 at the discharging station is pressed by the right-angle lifting plate 3, the clamp is “opened”, and the enamel cup falls onto the discharging conveyor 7.

The gear set can be a speed reduction gear set, so that the half gear 111 can better drive the first gear 107 and the second gear 110 to rotate.

[0052] In the above embodiment, specifically referring to Figure 9 , the third driving device 4052 and the movable frame 4053 are connected through a transmission assembly 4054. The transmission assembly 4054 comprises a transmission gear and a belt pulley assembly. The third driving device 4052 and the movable frame 4053 are connected through the transmission assembly 4054, so that the angle of the movable frame 4053 can be accurately adjusted, and the staff can perform decal on the enamel cup in a more comfortable posture.

[0053] In the above embodiment, specifically referring to Figure 8The side of the multi-group linkage frame 502 is provided with a guide slope, which can guide and extrude the two groups of linkage blocks 4058 of the vessel clamping mechanism 405, and by setting the side of the linkage frame 502 as a guide slope, the linkage frame 502 can extrude the linkage blocks 4058, so that the two groups of clamping blocks 4057 of the vessel clamping mechanism 405 can be close to or away from each other, thereby realizing the closing / opening of the clamp.

[0054] In the above embodiment, please refer to Figure 7 The flexible material is additionally arranged between the abutting surface between the second guide column 403 and the movable arm 4051, which is used for buffering the movable arm 4051 when the height of the movable arm 4051 changes, and the flexible material such as a rubber sleeve is additionally arranged between the abutting surface between the second guide column 403 and the movable arm 4051, which can buffer the movable arm 4051 when the height of the movable arm 4051 changes, so as to prevent the vessel clamping mechanism 405 from being impacted by too large force and the enamel cup from falling.

[0055] In the above embodiment, please refer to Figure 6 When the vessel clamping mechanism 405 is operated to the decal position, the third driving device 4052 works to drive the movable frame 4053 to rotate and tilt through the transmission assembly 4054, so as to make the enamel cup tilt towards the operator, and by adjusting the vessel clamping mechanism 405 at the decal position, the enamel cup can tilt towards the operator, so that the operator can more conveniently perform the decal work.

[0056] In the specific work, from the overall operation process of the device, the feeding conveying device 6 transports multiple enamel cups in order to the feeding position through the PCL program control combined with an industrial camera and a sensor positioning, and the device main body is divided into an empty position, a feeding position, a decal position and a discharging position.

[0057] The vessel clamping mechanism 405 at the empty position is gradually rotated to the discharging position and described as follows:

[0058] The first step is to rotate the rotating conveying mechanism 4 as a whole by the second driving device 402 to alternate the flow between different workstations. The rotating conveying mechanism 4 will also drive the linkage pressing plate 5 to rotate synchronously. The linkage pressing plate 5 is connected with the first threaded rod 108 through the connecting rod 503, so the rotation of the connecting rod 503 will interfere with the first threaded rod 108. When the idle workstation vessel clamping mechanism 405 rotates into the feeding workstation, the guide wheels 4059 at the bottom of the vessel clamping mechanism 405 are guided by the arc-shaped lifting plate 2, so that the vessel clamping mechanism 405 slides along the second guide column 403 to compress the first spring 404 and rise as a whole. After the vessel clamping mechanism 405 rises, the two groups of linkage blocks 4058 are pressed by the linkage frame 502 of the linkage pressing plate 5, and then the two groups of clamping blocks 4057 of the vessel clamping mechanism 405 are compressed to open the clamps, that is, the vessel clamping mechanism 405 in the feeding workstation rotates and rises at the same time to open the clamps. At this time, the vessel clamping mechanism 405 and the linkage frame 502 keep a contraction distance, and the vessel clamping mechanism 405 moves to the top of the feeding conveying device 6 to clamp the porcelain cup.

[0059] The corresponding vessel clamping mechanism 405 in the decal workstation does not have structures such as the arc-shaped lifting plate 2, so the height of the vessel clamping mechanism 405 does not change, that is, the vessel clamping mechanism 405 and the linkage frame 502 keep an initial distance, the linkage frame 502 does not act on the vessel clamping mechanism 405, and then the vessel clamping mechanism 405 is in a state of clamping the porcelain cup. The third driving device 4052 works through the transmission assembly 4054 to drive the movable frame 4053 to rotate by about 210°, so that the porcelain cup clamped by the vessel clamping mechanism 405 is inclined towards the worker, and the worker can manually decal the porcelain cup.

[0060] The corresponding vessel clamping mechanism 405 in the discharging workstation has the guide wheels 4059 at the bottom flush with the height of the right-angle lifting plate 3, so that the height of the vessel clamping mechanism 405 does not change, that is, the vessel clamping mechanism 405 and the linkage frame 502 keep an initial distance, the linkage frame 502 does not act on the vessel clamping mechanism 405, and the vessel clamping mechanism 405 is also in a state of clamping the porcelain cup.

[0061] The second step is to start the first driving device 112, the first driving device 112 drives the half gear 111 to rotate, the half gear 111 is first engaged with a group of speed reducer gear sets to drive the second gear 110 to rotate, and then the second gear 110 and the lifting plate 104 are threadedly engaged, so that the height of the lifting plate 104 is lowered, and then all structures on the top of the lifting plate 104, such as the arc-shaped lifting plate 2, the rotary material conveying mechanism 4 and the linkage pressing plate 5, are synchronously lowered, wherein the lowering of the lifting plate 104 drives the first threaded rod 108 and the connecting rod 503 of the linkage pressing plate 5 to synchronously lower, so that the first threaded rod 108 slides along the outer wall of the square rod 106, the overall height of the rotary material conveying mechanism 4 is lowered, that is, the height of the vessel clamping mechanism 405 of the feeding station is lowered, and since the linkage frame 502 of the linkage pressing plate 5 and the arc-shaped lifting plate 2 are synchronously lowered with the vessel clamping mechanism 405 at this time, the relative position between the vessel clamping mechanism 405 and the linkage frame 502 still maintains the “shrinkage distance”, that is, the clamp of the vessel clamping mechanism 405 is still in the “open” state, and the lowering of the vessel clamping mechanism 405 will make it fit the bottom of the top porcelain cup of the feeding conveying device 6;

[0062] Correspondingly, the porcelain cup of the decal station has completed the decal work by manual work, and the vessel clamping mechanism 405 will also change in height, and the third driving device 4052 of the decal station can adjust the angle of the porcelain cup so that the cup mouth faces directly downward, so as to facilitate the entry into the discharging station in the following step;

[0063] Correspondingly, in the discharging station, the overall height of the rotary material conveying mechanism 4 will drive the vessel clamping mechanism 405 of the discharging station to also lower in height, and the right-angle lifting plate 3 located at the top of the mounting table 102 does not change in height, so that the vessel clamping mechanism 405 of the discharging station does not change in height under the extrusion of the right-angle lifting plate 3, but the overall height of the rotary material conveying mechanism 4 will also drive the linkage frame 502 of the linkage pressing plate 5 to lower in height, and then the linkage frame 502 extrudes the vessel clamping mechanism 405 of the discharging station, so that the vessel clamping mechanism 405 and the linkage frame 502 maintain the “shrinkage distance”, and the clamp changes from the natural “closed” state to the “open” state, that is, the porcelain cup after the decal is completed will fall to the top of the discharging conveying device 7 and be transported to the designated area.

[0064] Third step - the first drive device 112 continues to drive the half gear 111 to rotate, the half gear 111 engages with another group of speed reducer gear set to drive the first gear 107 to rotate, the first gear 107 drives the square rod 106 to rotate, and then the square rod 106 drives the first threaded rod 108 to rotate, so that the first threaded rod 108 is higher than the lifting plate 104, the first threaded rod 108 is raised to push the connecting rod 503 to rise, and then the whole linkage pressing plate 5 is raised, so that the distance between the vessel clamping mechanism 405 of the feeding station and the linkage frame 502 changes from “shrinkage distance” to “initial distance”, and then the linkage frame 502 is separated from the vessel clamping mechanism 405, and the two groups of clamping blocks 4057 of the vessel clamping mechanism 405 are clamped under the reset action of the second spring 4056, that is, the clamp naturally “closes” to fix the porcelain cup.

[0065] Next, continue to rotate the whole rotating feeding mechanism 4 by the second drive device 402 to carry out the alternate circulation of the station. When the station is preliminarily rotated and circulated, the vessel clamping mechanism 405 of the feeding station is separated from the arc-shaped lifting plate 2 and is lowered to the lowest point under the reset action of the first spring 404, further away from the linkage frame 502, at this time, the first drive device 112 needs to be started in reverse to reset the height of the linkage pressing plate 5 and the height of the lifting plate 104, so as to continue to repeat the above steps after the station is alternated.

[0066] Although the embodiments of the present application have been shown and described, the specific embodiments are only an explanation of the present application, and are not a limitation of the application.
