[0036] Reference Figures 1 to 8 As shown, an embodiment of the present invention provides a loading and unloading device for a hot bending machine, including a frame 1, a manipulator 2, a precision positioning device 3, a transport module and a cleaning device 5. The frame 1 is provided with a manipulator 2, and both sides of the manipulator 2 are respectively provided with a semi-finished material rack 11 and a finished product material rack 12. The manipulator 2 is provided with a precision positioning device 3 on the side close to the cleaning device 5. The transport module includes an XY-axis slide module 41 and a module clamp 42. The XY-axis slide module 41 is arranged on the frame 1, and the XY-axis slide module 41 is provided with a module clamp 42. A cleaning device 5 is provided below the module clamp 42. The cleaning device 5 includes a frame 51, a flipping mechanism and a brush assembly. The frame 51 is arranged on the frame 1, and a brush assembly is provided on the frame 51. A flipping mechanism is provided on one side of the frame 51.

[0037] The flipping mechanism includes a rotating fixed seat 521, a rotating shaft 522, a movable block 523, a bottom plate 524 and a first driving source 525. The rotating fixed seat 521 is arranged on one side of the frame 51 of the frame 1. The rotating fixed seat 521 is provided with a rotating shaft 522. The movable block 523, the bottom plate 524 and the first driving source 525 constitute a flipping structure rotating around the rotating shaft 522. Specifically, the rotating shaft 522 is provided with a movable block 523, the movable block 523 is connected to one side of the bottom plate 524, and the bottom plate 524 is provided with a plurality of side positioning blocks for positioning the mold on the side facing the frame 51 after flipping. The other side of the bottom plate 524 is connected to the first driving source 525. Preferably, the first driving source 525 is preferably a cylinder. In actual operation, the cylinder can drive the bottom plate 524 to flip around the rotating shaft 522 through the movable block 523. The flip mechanism also includes a side positioning part 526, and the bottom plate 524 is provided with a side positioning part 526 on the other side of the relative rotation fixing seat 521, and the side positioning part 526 is configured to fix or loosen the bottom plate 524. Preferably, the side positioning part 526 includes a side block, a third driving source 321 and a push rod, and the third driving source 321 is provided on the side block. The driving end of the third driving source 321 is connected to the push rod, and the push rod penetrates the side wall of the side block. The push rod is driven by the third driving source 321 to move closer to or away from the bottom plate 524, thereby achieving the fixing or loosening of the bottom plate 524 by the side positioning part 526. For example, the third driving source 321 is a cylinder. Of course, the present invention can also be a side positioning part 526 of other structures, and the present invention is not limited thereto.

[0038] Considering the problem that the glass is easy to adhere when the module clamp 42 grabs the upper mold. The flip mechanism of the present invention also includes a purge assembly 527, and the purge assembly 527 is symmetrically provided on the other two sides of the bottom plate 524. Preferably, the purge assembly 527 includes a nozzle, an air pipe, a connecting block 324 and a fourth driving source 321. The fourth driving source 321 is fixed on the frame 1. The driving end of the fourth driving source 321 is connected to the connecting block 324. The connecting block 324 is provided with a nozzle, and a plurality of air injection holes are provided on the air outlet side of the nozzle. The nozzle is connected to the air pipe, and the air pipe is connected to the air source. Preferably, the fourth driving source 321 is a cylinder. In the process of the module clamp 42 grabbing the upper mold, the nozzle blows air to the glass all the time to prevent the glass from adhering to the upper mold, and the distance between the nozzle and the bottom plate 524 can be adjusted by the cylinder according to actual needs, which is convenient and practical.

[0039] During the process of opening and closing the mold, dust or dirt will adhere to the mold cavity. If the semi-finished product to be processed is placed directly after the finished product is taken out, it is easy to cause the surface of the finished product to be uneven due to the large amount of dirt in the mold cavity. Therefore, the brush assembly of the present invention includes a first brush 531, a second brush 532, a connecting rod 533 and a second driving source 534. The second driving source 534 is provided on the other side of the frame 51 away from the flip mechanism. The second driving source 534 is connected to the connecting rod 533 in transmission. The first brush 531 is provided at one end of the connecting rod 533, and the other end of the connecting rod 533 passes through the frame plate of the frame 51, and the second brush 532 is provided at the port. The frame plate of the frame 51 facing the second brush 532 is provided with an opening slightly larger than the bottom plate 524. After the finished product in the mold is taken out, the present invention needs to clean the mold before loading the semi-finished product to be processed. The mold cleaning process is as follows: the first driving source 525 is actuated to drive the bottom plate 524 to flip around the rotating shaft 522 through the movable block 523 until the lower mold on the bottom plate 524 contacts the second brush 532 through the opening on the frame plate. In the step of opening the upper mold, the upper mold has been moved to the position of the first brush 531 by the mold group clamp 42. Therefore, the second driving source 534 (preferably a cylinder here) drives the connecting rod 533 to perform reciprocating linear motion, and the inner surfaces of the upper mold and the lower mold are cleaned respectively by the first brush 531 and the second brush 532.

[0040] In order to ensure the accuracy of finished product unloading and semi-finished product loading, the present invention requires the robot 2 to perform precision positioning operation on the finished product and the semi-finished product through the precision positioning device 3 before the finished product unloading and the semi-finished product loading. Figure 2As shown, the precision positioning device 3 of the present invention includes a calibration platform 31 and a calibration component. The calibration platform 31 is arranged on the frame 1, and the calibration component is arranged on the calibration platform 31. The calibration component includes a calibration part and a limit stopper 33. The adjacent side of the calibration platform 31 is provided with the calibration part, and the other adjacent side of the calibration platform 31 is provided with a limit stopper 33. Specifically, a single calibration part includes a cylinder, a connecting plate 322, a guide sleeve 327, a positioning rod 323, a connecting block 324, a positioning column 325 and a roller 326. A cylinder is arranged at the bottom of the calibration platform 31, and the driving end of the cylinder is connected to the connecting plate 322 in a transmission manner. The positioning rod 323 passes through the connecting plate 322 through the guide sleeve 327. A connecting block 324 is arranged at one end of the positioning rod 323, and a positioning column 325 is arranged on the connecting block 324. A roller 326 is rotatably arranged on the positioning column 325. In addition, the calibration component also includes a cushion block 34. A plurality of cushion blocks 34 are arranged on the calibration platform 31, and the other end of the cushion block 34 relative to the calibration platform 31 is a hemispherical structure. When in action, the robot 2 places the semi-finished product to be processed on the calibration table 31. When there is a deviation in the position of the semi-finished product, the cylinder is activated to drive the positioning rod 323 through the connecting plate 322 to push the semi-finished product to adjust the position of the semi-finished product. The two calibration parts are used for adjustment in two directions respectively, and each calibration part fixes the semi-finished product through the roller 326. The roller 326 will not interfere with the movement of the semi-finished product while fixing the semi-finished product.

[0041] The semi-finished product to be processed needs to be surface cleaned before loading. Therefore, the present invention also includes an ion wind cleaning station, and the frame 1 is provided with an ion wind cleaning station on the other side of the precision positioning seat relative to the manipulator 2. The ion wind cleaning station is a prior art that has been disclosed and widely used in the mechanical field, so the invention will not be described in detail here.

[0042] A method for loading and unloading a hot bending machine of the present invention is as follows:

[0043] During operation, first, the XY-axis slide module 41 moves the mold loaded with the finished product to the bottom plate 524 of the flipping mechanism, and the module clamp 42 lifts the upper mold of the mold and moves it to the position of the first brush 531. At the same time, the purge component 527 keeps blowing on the mold to prevent the finished product (here refers to glass) from adhering to the upper mold; then the robot 2 grabs the finished product on the mold, places the finished product on the precision positioning plate, and then the robot 2 grabs the finished product on the precision positioning plate and moves the finished product to the finished product rack 12; then the first driving source 525 (here refers to the cylinder) is actuated to drive the bottom plate 524 to flip around the rotating shaft 522 until the lower mold on the bottom plate 524 contacts the second brush 532 through the opening on the frame plate, and after the upper mold and the lower mold are in contact with the first brush 531 and the second brush 532 respectively, the second driving source 534 The robot 2 grabs the semi-finished product on the semi-finished product rack 11 and moves the semi-finished product to the ion wind cleaning station for cleaning. After cleaning, the robot 2 moves the semi-finished product to the precision positioning plate. Then, the robot 2 grabs the semi-finished product on the precision positioning plate and moves the semi-finished product to the cleaned lower mold. Then, the module clamp 42 grabs the cleaned upper mold and covers the upper mold on the lower mold through the XY-axis slide module 41. Finally, the module clamp 42 grabs the mold loaded with the semi-finished product and moves it to the hot bending machine for processing through the XY-axis slide module 41. In this way, the loading and unloading cycle of the hot bending machine is realized.

[0044] The present invention takes the finished product discharged by the hot bending machine out of the mold and places it on the finished product rack 12, then cleans the semi-finished product to be processed and the mold respectively, and then places the cleaned semi-finished product in the mold and transports it to the hot bending machine for loading, thus realizing the loading and unloading cycle operation of the hot bending machine, greatly improving the work efficiency, and significantly reducing the problem of raised surface of the finished product caused by dirt on the surface of the product or mold, thereby greatly reducing the scrap rate.
