That is, the loading tray 1011 and the unloading tray 1021 adopt the existing drawer structure; a support rail is provided in the heat bending box 1, and the loading tray 1011 and the unloading tray 1021 are inserted into the heat bending box 1 from the storage port and placed on the support rail. Figure 5-6 As shown, the loading tray 1011 and the unloading tray 1021 are provided with a groove 2 with a depth of 5 mm, a mold carrier 3 is placed in the groove 2, and a mold 4 is placed in the mold carrier 3; after the pull-out loading tray 1011 and the unloading tray 1021 are pulled out of the hot bending box 1, the mold carrier 3 and the mold 4 are placed.

[0029] like Figure 2 and 5 As shown, the hot bending forming unit includes six heating chambers 103 from top to bottom, and the heating chambers 103 correspond to the loading tray 1011 and the unloading tray 1021 one by one. A heating mechanism is provided in the heating chamber 103, and the heating mechanism includes a high-frequency induction heating coil 1031 laid in the heating chamber 103, and the high-frequency induction heating coil 1031 is connected to a high-frequency induction heating machine 1032, and the high-frequency induction heating machine 1032 is electrically connected to the control system. The high-frequency induction heating machine 1032 heats the mold carrier 3 and the mold 4 placed in the heating chamber 103 through the high-frequency induction heating coil 1031.

[0030] like Figure 2-4 As shown, a moving unit is also provided in the hot bending box 1, and the moving unit includes a lateral moving mechanism and a longitudinal moving mechanism. The moving unit is connected to a grabbing mechanism, and the grabbing and transfer of the mold carrier 3 between the loading unit 101 and the hot bending forming unit and between the hot bending forming unit and the unloading unit 102 are realized through the grabbing mechanism and the moving unit.

[0031] Among them, Figure 3-4As shown, the grabbing mechanism includes a back plate 501, and six mounting plates 502 are arranged on the back plate 501 from top to bottom, and the mounting plates 502 correspond to the heating chambers 103 one by one; a gripper is installed on the mounting plate 502, and the mold carrier 3 is grabbed by the gripper. Specifically, the gripper includes a first motor 503 installed on the mounting plate 502, and the first motor 503 is electrically connected to the control system; a worm 504 is connected to the output shaft of the first motor 503, and worm wheels 505 are respectively connected to the two sides of the worm 504, and the two worm wheels 505 are respectively meshed with a left moving plate 506 and a right moving plate 507, and the left moving plate 506 and the right moving plate 507 are respectively horizontally connected with a support plate 508, and the support plate 508 is at an angle of 90° with the left moving plate 506 and the right moving plate 507; the left and right sides of the mold carrier 3 are respectively provided with supporting edges 301, and the support plate 508 lifts the supporting edge 301 of the mold carrier 3 to grab the mold carrier 3. Preferably, a protrusion 5081 is provided on the upper surface of the support plate 508, and a notch 3011 is provided in the middle of the supporting edge 301 of the mold carrier 3. When the support plate 508 extends into the bottom of the supporting edge 301 to lift the supporting edge 301, the protrusion 5081 passes through the notch 3011, plays a limiting role, and prevents the mold carrier 3 from sliding out of the front end of the support plate 508. Further, a slide rail 5021 is provided on the mounting plate 502, and a slide groove is provided on the left movable plate 506 and the right movable plate 507 and is slidably arranged on the slide rail 5021 through the slide groove. The first motor 503 drives the worm 504 to rotate, driving the worm gears 505 on the left and right sides to rotate in the opposite direction, and then drives the left movable plate 506 and the right movable plate 507 meshed with the worm gear 505 to move in opposite directions along the slide rail 5021, so that the distance between the two side support plates 508 changes, and finally the mold carrier 3 is taken and placed.

[0032] like Figure 2-4 As shown, the lateral movement mechanism includes a second motor 601 installed in the heat bending box 1, and the second motor 601 is electrically connected to the control system; the second motor 601 is installed on two oppositely arranged vertical rods 605 and two horizontally arranged guide rods 604 are arranged from top to bottom between the two vertical rods 605, and the vertical rods 605 and the guide rods 604 constitute a support frame, and the support frame is fixed on the inner wall of the heat bending box 1. The output shaft of the second motor 601 is horizontally connected to the first screw rod 602, and the first screw rod 602 is connected to the movable plate 603. A dovetail-shaped guide groove 6031 is vertically arranged on the side surface of the movable plate 603 facing the heating chamber 103, and a guide block 5011 is arranged on the back plate 501. The guide block 5011 is inserted into the guide groove 6031, so that the back plate 501 can slide up and down on the movable plate 603; two upper and lower rings are arranged on the side surface of the movable plate 603 facing away from the heating chamber 103, and the rings are mounted on the guide rod 604 so that the movable plate 603 can move left and right along the guide rod 604.

[0033] like Figure 2-4As shown, the longitudinal moving mechanism includes a third motor 701, which is fixed on the moving plate 603 and electrically connected to the control system; the output shaft of the third motor 701 is vertically connected to the second screw rod 702, and the second screw rod 702 is connected to the back plate 501, so that the back plate 501 can move up and down on the second screw rod 702.

[0034] Working principle:

[0035] The mold 4 to be bent is placed in the mold carrier 3, and the loading tray 1011 is sequentially pulled out from the loading unit 101 of the bending box 1, and the mold carrier 3 with the mold 4 is placed on the loading tray 1011, and then the loading tray 1011 is sequentially placed in the bending box 1. A first proximity switch is set at the position corresponding to each loading tray 1011 in the bending box 1. When all the first proximity switches detect that the mold carrier 3 is placed in the bending box 1, a signal is fed back to the control system, and the control system controls the second motor 601 of the lateral moving mechanism to start, drive the first screw rod 602 to rotate, and move the moving plate 603 to the loading unit 101. Then the control system controls the first motor 503 to start, and drives the left moving plate 506 to move to the left and the right moving plate 507 to move to the right through the worm gear 504, so that the distance between the left and right support plates 508 on each mounting plate 502 becomes larger (greater than the distance between the left and right supporting edges 301 of the mold carrier 3). Next, the control system controls the third motor 701 of the longitudinal moving mechanism to start, driving the second screw rod 702 to rotate, so that the back plate 501 moves downward on the moving plate 603 along the guide groove 6031 until the support plate 508 moves to the bottom of the supporting edge 301. The control system then controls the first motor 503 to rotate in the opposite direction, and drives the left moving plate 506 to move rightward and the right moving plate 507 to move leftward through the worm gear 504, so that the distance between the left and right support plates 508 on each mounting plate 502 becomes smaller (less than the distance between the supporting edges 301 on the left and right sides of the mold carrier 3). At this time, the control system controls the third motor 701 of the longitudinal moving mechanism to rotate in the opposite direction, driving the second screw rod 702 to rotate in the opposite direction, so that the back plate 501 moves upward on the moving plate 603 along the guide groove 6031, until the support plate 508 supports the supporting edge 301 so that the mold carrier 3 is lifted upward, and the mold carrier 3 is grasped.

[0036] After the gripper grabs the mold carrier 3, the control system controls the second motor 601 of the lateral moving mechanism to start, driving the first screw 602 to rotate, so that the movable plate 603 moves to the heating chamber 103 of the hot bending forming unit. Then the control system controls the third motor 701 of the longitudinal moving mechanism to start, driving the second screw 702 to rotate, so that the back plate 501 moves downward along the guide groove 6031 on the movable plate 603 until the mold carrier 3 is placed in the heating chamber 103. The control system then controls the first motor 503 to start, and drives the left movable plate 506 to move to the left and the right movable plate 507 to move to the right through the worm gear 504, so that the distance between the left and right support plates 508 on each mounting plate 502 becomes larger (greater than the distance between the left and right supporting edges 301 of the mold carrier 3). Next, the control system controls the third motor 701 of the longitudinal moving mechanism to start, driving the second screw 702 to rotate, so that the back plate 501 moves upward on the moving plate 603 along the guide groove 6031, so that the mounting plate 502 rises to the original height, and the transfer of the mold 4 from the loading unit 101 to the hot bending unit is completed. The high-frequency induction heating coil 1031 heats the mold carrier 3 and the mold 4 placed in the heating chamber 103 through the high-frequency induction heating machine 1032, and the upper mold weight of the mold 4 is used to complete the hot bending of the glass.

[0037] After the hot bending process is completed, the mold carrier 3 needs to be transferred from the hot bending molding unit to the unloading unit 102, and finally the mold carrier 3 needs to be taken out from the unloading unit 102. This operation process is the same as the transfer process of the mold carrier 3 from the loading unit 101 to the hot bending molding unit, and will not be repeated here. A second proximity switch is set at the position corresponding to each unloading tray 1021 in the hot bending box 1. When all the second proximity switches detect that the mold carrier 3 is transferred to the unloading tray 1021, a signal is fed back to the control system, and the staff pulls out the unloading tray 1021 from the storage port of the hot bending box 1, takes out the mold carrier 3 and the mold 4, and then puts the unloading tray 1021 back.

[0038] The hot bending processing equipment of this embodiment can perform hot bending processing on multiple glass products at one time, and by laying the high-frequency induction heating coil 1031 in the heating chamber 103, uniform heating of the hot-bent glass can be achieved. It has the advantages of simple equipment, low manufacturing cost, simple operation, and high production efficiency.
