Description

Technical Field

[0001] The present invention relates to the technical field of glass sheet transmission, and in particular to a high-precision and high-efficiency glass sheet transfer device. Background Art

[0002] On a glass sheet production line, after the glass sheets complete a designated process, they need to be collectively transferred to the next process, such as collectively transferring the glass sheets to a material rack.

[0003] The material rack is a commonly used tool for storing glass pieces. When the glass pieces are placed in the material rack, they can be isolated from each other by a certain distance, making them less likely to be scratched. The glass pieces in the material rack can also be easily taken out by the robot.

[0004] In the prior art, the transfer of glass sheets from the assembly line platform to the material rack mechanism is often done manually, which is slow and inefficient.

[0005] An automatic rack inserting machine and rack inserting system are disclosed in the patent document with Chinese patent application number 201821594423.0. The automatic rack inserting machine includes a manipulator, a positioning mechanism, a transfer mechanism and a frame; the manipulator, the positioning mechanism and the transfer mechanism are all connected to the frame; the manipulator can grab the glass pieces on the assembly line platform and send them into the positioning mechanism; the transfer mechanism can grab the glass pieces on the positioning mechanism and send them into the rack inserting mechanism. The rack inserting system includes the automatic rack inserting machine. This utility model provides an automatic rack inserting machine and a rack inserting system to solve the technical problems in the prior art of slow speed and low efficiency in transferring glass pieces from the assembly line platform to the rack inserting mechanism.

[0006] However, the positioning mechanism of the utility model realizes positioning through a positioning column in one direction and a push rod in the other direction. However, the push rod is fixed on the positioning platform. Therefore, when the push rod pushes the glass sheet to move, it is easy for the glass sheet to be unable to be pushed in the gap between the push rod and the positioning platform. This easily causes the vertical distance of the glass sheet to be offset during positioning, and when the push rod pushes the glass sheet, the glass sheet is easily squeezed and damaged.

[0007] At the same time, this structure only positions the glass sheet before it is placed in the rack mechanism. However, since the glass sheet is easily moved when inserted into the rack mechanism, the positioning of the entire transfer device may be inaccurate. Summary of the Invention

A second material rack positioning baffle 238 is provided on the rotary table 222 at the other end of the material rack 223. Therefore, the glass pieces after being positioned by the positioning device are transferred to the material rack on the material rack table by the manipulator. When the material rack is full and replaced with a new one, the new material rack is pushed for positioning by the first material rack positioning cylinder and the second material rack positioning cylinder. This ensures that the manipulator device will not cause the glass pieces to be misplaced due to the movement of the material rack during transportation, thereby further improving the high precision and high efficiency of the equipment.

[0049] The equipment of the above structure, when conveying, places the material plate filled with glass pieces on the feeding device, and the feeding device can convey the material plates to the positioning mechanism one by one. When the material plate is conveyed to the positioning mechanism, the positioning conveying mechanism grabs two or more glass pieces and conveys them to the positioning mechanism. When the positioning conveying mechanism places the glass pieces into the positioning grooves of the positioning mechanism, the empty material plates are conveyed to the recycling device through the conveying device for recycling. The X-axis positioning assembly and the Y-axis positioning assembly are started at the same time to push the glass pieces toward the X-axis positioning baffle and the Y-axis positioning baffle. The glass pieces contact the X-axis positioning baffle. After the X-axis positioning is completed, the Y-axis positioning can be completed when the glass piece contacts the positioning partition and the Y-axis positioning baffle. The positioning process is fast and accurate, and the setting of the positioning baffle and the positioning partition makes it possible to adapt to glass pieces of different specifications. After the positioning is completed, the glass piece can be transferred to the loading table by the robot device, thereby completing the entire transfer operation with high transmission efficiency. At the same time, since the loading table is provided with a second positioning mechanism for positioning the material rack, the glass piece located on the positioning mechanism is transferred to the loading table and then the material rack is positioned for the second time, thereby further improving the positioning accuracy.
