Description

Technical Field

[0001] The utility model relates to the technical field of hot bending machines, in particular to double-station automatic loading and unloading equipment for hot bending machines. Background Art

[0002] In the past, the hot bending machines used to process glass needed to be loaded and unloaded manually, which resulted in low production efficiency. Later, someone invented an automated robot for loading and unloading, but it could only perform simple material picking and feeding, which improved efficiency. However, it was easy to cause defects in the workpiece to be processed and a high scrap rate. For this reason, someone invented a fully automatic hot bending machine loading and unloading equipment to solve these problems.

[0003] In the patent document with the authorization announcement number CN218370508U and the authorization announcement date 2023.01.24, an automatic loading and unloading device for a hot bending machine is disclosed, which includes a frame, a manipulator, an upper bin assembly, a lower bin assembly, a secondary positioning assembly, an XZ axis handling module and a mold cleaning assembly. The manipulator is arranged on the frame; the upper bin assembly and the lower bin assembly are respectively arranged on both sides of the manipulator, and the fine positioning device is arranged on the side of the manipulator close to the mold cleaning device. A mold shifting bottom plate is provided on the frame, and the mold cleaning assembly includes a lower mold cleaning and positioning assembly and an upper mold cleaning assembly; in this structure, the mold positioning flip plate can be made at any angle Rotational motion: when the mold positioning flip plate rotates 180 degrees and the cavity of the lower mold faces completely downward, the first brush is started at this time, and all the dust and other foreign matter brushed off can fall down, achieving the best cleaning effect. A dust collecting hopper can be set up to collect fallen foreign matter to prevent environmental pollution. After negative pressure is connected to the outlet of the dust collecting hopper, suction can be generated on dust and other foreign matter, and the effect of collecting foreign matter will be better. With the above setting of the manipulator, before the manipulator takes the processed workpiece, the rotating grasping mechanism can first carry a workpiece to be processed. The manipulator can realize the loading and unloading of the workpiece in one reciprocating motion, which can greatly improve the working efficiency of the manipulator.

[0004] However, one such automatic loading and unloading device can only be used with one hot bending machine. Usually, the device is arranged on the side of one end of the hot bending machine, so that the hot bending machine and the automatic loading and unloading device form an L-shaped layout. When there are many hot bending machine production lines in the workshop, this layout will take up a lot of space, resulting in high production costs. Therefore, it is necessary to design an automatic loading and unloading device that can reasonably layout the workshop and effectively utilize the factory area to reduce the manufacturing cost of the machine and the production cost of the workpiece. Summary of the invention

[0005] In order to solve the problems existing in the prior art, the utility model provides a double-station automatic loading and unloading equipment for a hot bending machine. Through a new structural design, the problems of unreasonable layout, large floor space and high production cost caused by the combination of automatic loading and unloading equipment and hot bending machines in the prior art are solved.

When starting work, the mold is provided to the mold cache and conveying mechanism in advance or manually, and the XZ-axis handling module 5 picks up the mold from the mold cache and conveying mechanism 3 and transports it to the mold cleaning component 4. The XZ-axis handling module 5 further picks up the upper mold, and the mold cleaning component 4 performs the mold cleaning action. The manipulator 2 picks up the workpiece to be processed and puts it into the lower mold after precise positioning. The XZ-axis handling module 5 closes the upper mold on the lower mold, and the XZ-axis handling module 5 then puts the mold filled with the workpiece The mold is transported to the mold transmission transition device 6, the mold transmission transition device 6 rotates and transports the mold, and transports the mold to the hot bending machine. After processing by the hot bending machine, the mold is output from the mold outlet of the hot bending machine and returned to the mold transmission transition device 6, and the XZ-axis transport module 5 transports the mold from the XZ-axis transport module 5 to the mold cleaning component 4, and performs the same mold opening action. The manipulator 2 takes out the processed workpiece, and the mold is cleaned. The manipulator 2 puts the workpiece to be processed into the lower mold. After the mold closing action, the XZ-axis transport module 5 transports the mold filled with the workpiece to the mold transmission transition device 6 again to form a cycle. After all processing is completed, the mold with the workpiece taken out will be transported to the mold cache and conveying mechanism 3 by the XZ-axis transport module 5 to store the mold.

[0094] This solution solves the problems of unreasonable layout, large floor space and high production cost caused by the combination of automatic loading and unloading equipment and hot bending machines in the prior art through a new structural design.
