Description

Technical Field

[0001] The utility model relates to the technical field of hot bending machines, in particular to a mold transmission transition device of double-station automatic loading and unloading equipment. 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.

[0005] When designing the automatic loading and unloading equipment, it is necessary to consider the path through which the mold coming out of the heat bending machine is transferred to the automatic loading and unloading equipment, and then transferred from the automatic loading and unloading equipment to the die inlet of the heat bending machine. In this process, the mold needs to adjust the angle. Summary of the invention

[0026] Usually, the mold transfer transition device 6 is directly installed between the die outlet and the die inlet of the heat bending machine.

[0027] The mold transfer transition device 6 includes a base plate 60 .

[0028] In this embodiment, the base plate 60 is used to connect the die outlet and the die inlet of the heat bending machine.

[0029] A mold shifting assembly 61 for translating the mold is disposed on one side of the base plate 60 ; a turntable assembly 62 for rotating the mold is disposed on the base plate 60 .

[0030] The mold shifting assembly 61 includes a mold shifting driving device disposed on the side of the substrate 60.

[0031] In this embodiment, the mold shifting drive device is a magnetically coupled rodless cylinder 610. The cylinder bodies at both ends of the magnetically coupled rodless cylinder 610 are connected to the substrate 60 through an L-shaped fixing block 611. The L-shaped fixing block 611 can not only be stably connected to the substrate 60, but also can be used to support the magnetically coupled rodless cylinder 610, making the structure more stable.

[0032] A first mounting plate 612 is provided on the slider of the magnetically coupled rodless cylinder 610, the middle part of the first mounting plate 612 is connected to the slider of the magnetically coupled rodless cylinder 610, a pusher claw lifting drive device is provided at each end of the first mounting plate 612, and a pusher claw 613 is provided on the driving rod of the pusher claw lifting drive device.

[0033] In this embodiment, the pusher claw lifting drive device is a three-axis cylinder 614; the pusher claw 613 has a mounting portion 6130, the cross section of the mounting portion 6130 matches the cross section of the baffle of the three-axis cylinder 614, and the mounting portion 6130 is connected to the baffle of the three-axis cylinder 614 by bolts. This arrangement can ensure that the pusher claw 613 is reliably connected to the three-axis cylinder 614.

[0034] A horizontal drag chain bracket 615 is provided between the two L-shaped fixing blocks 611, a vertical drag chain bracket 616 is provided on the first mounting plate 612, and a drag chain 617 for passing air pipes and wires is provided on the horizontal drag chain bracket 615, one end of the drag chain 617 is connected to the horizontal drag chain bracket 615, and the other end of the drag chain 617 is connected to the vertical drag chain bracket 616. With this arrangement, when the magnetically coupled rodless cylinder 610 drives the first mounting plate 612 to move, the air pipes and wires connected to the three-axis cylinder 614 will be bound in the drag chain 617, and move as a whole with the movement of the first mounting plate 612, so that the machine is regular.

[0035] A circular through hole 600 is provided on the base plate 60, and a second mounting plate 620 is provided at the bottom of the circular through hole 600. In this embodiment, the second mounting plate 620 is a long strip plate, and the second mounting plate 620 is arranged perpendicular to the length direction of the base plate 60. This arrangement can simplify the structure and the operating procedures. Of course, the second mounting plate 620 does not necessarily have to be a long strip plate, as long as it can be used to fix the rotary drive device.

[0036] A rotary drive device is provided at the bottom of the second mounting plate 620 , and a turntable 621 is provided on the rotating shaft of the rotary drive device.

The baffles 64 adopt a segmented structure, and are locked by bolts from the bottom of the base plate 60. The setting of the baffles 64 can further prevent the mold from falling from the base plate 60.

[0041] The base plate 60 is used to support the mold. During production, the magnetically coupled rodless cylinder 610 is started, and the mold is transported to the turntable 621 through the first mounting plate 612 and the pusher claw 613; the rotary cylinder 622 is started, and the turntable 621 and the mold are rotated 90 degrees.

The rotary cylinder 622 is started again, and the turntable 621 and the mold are rotated 90 degrees in the opposite direction, and then the mold is sent to the mold inlet of the heat bending machine through the first mounting plate 612 and the pusher claw 613. This solution solves the problem of connecting the heat bending machine with the double-station automatic loading and unloading equipment through the simple structure by setting the base plate 60, the mold transfer assembly 61 and the turntable assembly 62.
