Description

Technical Field

[0001] The invention belongs to the technical field of glass production and relates to loading and unloading equipment of a hot bending machine. Background Art

[0002] Glass is an amorphous inorganic non-metallic material. It is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials are added. Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate complex salt, which is an amorphous solid with irregular structure. It is widely used in buildings to block wind and transmit light, and is a mixture. There are also colored glass that is mixed with certain metal oxides or salts to show color, and tempered glass made by physical or chemical methods. Sometimes some transparent plastics (such as polymethyl methacrylate) are also called organic glass.

[0003] Most of the glass is flat, but some is curved, such as car windshields, mobile phone screens, etc. Some curved glass is produced using flat glass, such as through a heat bending machine. The flat glass is placed between the upper mold and the lower mold, and the mass of the upper mold is supported by the glass (the upper mold will not break the rear glass).

[0094] The present invention provides a loading and unloading device for a hot bending machine. When hot bending the glass, the glass is first placed (either manually by a worker or automatically by a combination of a robot and a suction cup) in a forming groove 4, and then a second driving mechanism drives a negative pressure plate 9 (which is hollow and has multiple holes on the top, and an exhaust pipe is connected to the bottom or side to form a negative pressure in the negative pressure plate 9 and tightly adsorb the lower template 3) to move, and the negative pressure plate 9 moves the lower template 3 to the bottom of the upper template 5; then the upper template 5 moves downward or the lower template 3 moves upward until the forming protrusion 6 touches the top of the glass (at the same time, the inner wall of the upper mold cylinder 7 is attached to the outer wall of the lower mold body 2); then the suction mechanism stops adsorbing the upper template 5, and the clamping mechanism clamps the bottom of the lower template 3 (the clamping mechanism and The negative pressure plate 9 does not contact the lower template 3), and then the negative pressure plate 9 is separated from the lower template 3, and the clamping mechanism moves the entire upper mold, the lower mold and the glass to the loading place of the hot press under the action of the first driving mechanism (preferably, the width of the loading place of the hot press is smaller than the width of the lower template 3, so that when the lower template 3 is placed on the loading place, the lower template 3 can be directly placed on the loading place, such as a metal conveyor belt or chain, to prevent the lower template 3 from impacting the loading place and even damaging the glass); then the loading place of the heat bending machine 8 automatically sends the upper mold and the lower mold into the heat bending machine 8; a higher temperature is generated inside the heat bending machine 8, and at the same time, the upper mold applies a certain pressure to the glass, so that the glass is deformed under the action of high temperature and pressure, and finally the top of the glass is attached to the lower side of the molding protrusion 6, and the bottom is attached to the inner wall of the molding groove 4.

[0095] After the glass is formed, it is automatically sent to the unloading place by the hot bending machine 8. Then the clamping mechanism at the unloading place clamps the bottom of the lower template 3, and under the driving action of the first driving mechanism, the lower mold and the upper mold are transferred to the upstream end of the conveyor belt (the width of the conveyor belt 1 is smaller than the width of the lower template 3, so that the lower template 3 can be directly placed on the conveyor belt 1).

[0096] Driven by the motor, the conveyor belt 1 transfers the upper mold, the lower mold and the glass to the downstream end of the conveyor belt 1; then the clamping mechanism at the downstream end clamps the lower mold and moves it to the set position; then the suction mechanism sucks the upper mold plate 5, and the negative pressure plate 9 sucks the bottom of the lower mold plate 3, and then the clamping mechanism is released, the negative pressure plate 9 moves downward and / or the suction mechanism moves upward, so that the upper mold and the lower mold are separated, and the glass is now in the molding groove 4. Then the negative pressure plate 9 moves to the specified position, the bent glass at this position is taken away, and it is also the position where new glass is placed.

[0097] In the actual processing process, when the lower mold and the upper mold with the bent glass move to the end of the second conveying part 1b, they stop moving; then the first electric push rod 29 lowers the height of the lifting plate 30 (the lifting plate 30 is buckled on the lifting rail, and its position stability is guaranteed), and also lowers the height of the clamping plate 10, until all the negative pressure suction cups 17 are attached to the top of the upper mold plate 5, and the lifting plate 30 and the clamping plate 10 stop descending;

[0098] Then the first cylinder 13 drives the two clamping seats 12 to approach each other until the two clamping arms 14 are attached to the two ends of the lower mold (and also to the two ends of the upper mold cylinder 7), and the two clamping parts 15 are in contact with the bottom of the lower mold plate 3 (the two ends of the lower mold plate 3 are located at the outer ends of the second conveyor belt 1); then the first electric push rod 29 drives the lifting plate 30 and the clamping plate 10 to rise to a certain height;

[0099] Then, the motor on the horizontal frame 26 drives the screw rod to rotate, thereby driving the movable slide 27 to move along the length direction of the horizontal frame 26 until the upper mold and the lower mold move to the top of the first opening 37 and then stop moving; the first electric push rod 29 is started again to send the upper mold and the lower mold into the cleaning chamber 36 through the first opening 37;

[0100] At this time, the negative pressure plate 9 is raised under the drive of the third cylinder 33 until the negative pressure plate 9 is attached to the bottom of the lower mold plate 3, and negative pressure is formed in the negative pressure plate 9 to adsorb the bottom of the lower mold plate 3; then the first cylinder 13 drives the clamping arm 14 and the clamping part 15 to separate from the lower mold plate 3, and the negative pressure plate 9 moves downward under the drive of the third cylinder 33, and at the same time, the upper mold plate 5 is adsorbed by the negative pressure suction cup 17, so that the upper mold plate 5 remains motionless; in this way, the upper mold and the lower mold are separated, and the bent glass is located in the lower mold;

[0101] After the lower mold is separated from the upper mold, the second cylinder 20 drives the integrated plate 19 to descend to a certain height, and at the same time, the integrated plate 19, the guide rod 18 and the negative pressure suction cup 17 are all lowered, and the height of the upper mold plate 5 is also lowered; then the first cylinder 13 drives the clamping arm 14 and the clamping part 15 to approach each other, until the clamping part 15 enters the support groove 24, and makes the clamping part 15 contact the top of the inner wall of the support groove 24, so that the upper mold is supported by the negative pressure suction cup 17 and the clamping part 15 at the same time, ensuring that its position is fully stable; at this time, the position of the upper mold is maintained, waiting to be cleaned;

[0102] The third cylinder 33 drives the lower mold to move out of the cleaning chamber 36 through the second opening 38, and the second electric push rod drives the reciprocating seat 32 to move, so as to move the negative pressure plate 9 to a designated position; the bent glass at the designated position is removed (either manually by a worker or by a robot and a suction cup); then the second electric push rod and the third cylinder 33 deliver the empty lower mold through the second opening 38 into the cleaning chamber 36 to wait for cleaning;

[0103] After the upper mold and the lower mold have reached the specified position, the third electric push rod 40 drives the yield seat 41 to move toward the upper mold and the lower mold (when the upper mold and the lower mold are separated, the support plate 43 and the like are located on the sides of the upper mold and the lower mold, and do not affect the separation and combination of the upper mold and the lower mold), until the two cleaning heads 53 are located between the upper mold and the lower mold; then, compressed air is injected into the bottom of the upper cleaning head 53 by the pipeline, and compressed air is injected into the top of the lower cleaning head 53 by the pipeline, and the upper cleaning head 53 blows upward to form the protrusion 6, and the lower cleaning head 53 blows downward to form the groove 4; at the same time, the motor drives the first wheel body 49 to rotate, and the first wheel body 49 and the second wheel body 50 and the transmission belt 51 are both movable, and at the same time, the cleaning arm 46 is driven to move along the length direction of the cleaning column 42; at the same time, since the steering groove 44 guides the steering wheel 55, the steering wheel 55 can drive the steering arm 54 to swing, and at the same time, the steering rod 52 is driven to rotate, so that the cleaning head 53 not only moves horizontally, but also rotates at an angle, and the angle change of the cleaning head 53 is adapted to the shape of the molding protrusion 6 and the molding groove 4, that is, the cleaning head 53 moves horizontally while also swinging at an angle, so that the upper mold and the lower mold can be better cleaned.

[0104] After cleaning is completed, the clearance seat 41, cleaning ratio, cleaning head 53, etc. are all returned to their positions, waiting for the next use. At this time, the negative pressure plate 9 drives the lower mold downward, and then moves outward to the place where the lower glass is placed, where the new glass is placed; then the negative pressure plate 9 moves the lower mold into the cleaning cavity 36, and makes the bottom of the molding protrusion 6 touch the top of the glass; then the negative pressure of the negative pressure suction cup 17 disappears, and the second cylinder 20 raises the integrated plate 19, the suction plate 16 and the negative pressure suction cup 17 (the glass temporarily supports the upper mold); then the clamping part 15 moves outward and separates from the upper mold cylinder 7, and then the negative pressure plate 9 rises or the clamping plate 10 moves downward, and the clamping part After 15 is lower than the lower template 3, the clamping parts 15 approach each other and support the bottom of the lower template 3, then the negative pressure on the negative pressure plate 9 disappears, the lifting plate 30 rises, and the lower mold and the upper mold move from the first opening 37 to a height higher than the cleaning chamber 36; the movable slide 27 moves toward the loading position of the hot bending machine 8, and after moving to the top of the loading position, the lifting plate 30 descends and places the lower mold at the loading position, and then the clamping part 15 moves in the direction away from the lower mold and then rises, and then the upper mold and the lower mold are sent into the hot bending machine 8 for processing.

[0105] After the processed lower die and upper die are sent to the unloading place of the hot bending machine 8, the fourth cylinder 64 drives the transfer arm 63 to move toward the transfer rack 59. At this time, the pushing part 65 drives the pushing frame 66 to move, and the pushing frame 66 drives the lower die and the upper die to move from the unloading place to the transfer rack 59, wherein the transfer rack 59 is at the same height as the unloading place, and there is no gap or a small gap between the two.

[0106] The lower mold is driven to move to the transfer hole, and the push frame 66 is reset to wait for the next work; at this time, both sides of the lower mold plate 3 are in contact with the transfer frame 59, but both ends of the transfer hole are located on the outside of the lower mold plate 3; after the lifting plate 30 here descends, the bottom of the clamping arm 14 and the clamping part 15 pass through the transfer hole, and then the first cylinder 13 drives the clamping parts 15 to approach each other, and the two clamping parts 15 are in contact with the bottom of both ends of the lower mold plate 3; then the lifting plate 30 rises, directly moving the lower mold and the upper mold from the transfer frame 59 to the upstream end of the first conveying part 1a, and placing the lower mold at the upstream end of the first conveying part 1a. The upstream end of the first conveying part 1a is not limited by the first limit part 56, and the width of the first conveying part 1a is smaller than the width of the lower mold plate 3, so that the clamping plate 10 does not interact with the first conveying part 1a when descending.

[0107] The first conveying part 1a conveys the lower mold and the upper mold toward the second conveying part 1b. When passing through the transition roller 58, the powder on the upper mold and the lower mold will fall naturally, reducing the difficulty of subsequent cleaning. When the upper mold and the lower mold move to the downstream end of the second conveying part 1b, they wait for the clamping mechanism there to clamp them.

[0108] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
