DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Depend on Figure 1-9The present invention relates to a cutting device for glass crafts, comprising a conveying frame 1, a conveying mechanism for conveying glass crafts is arranged in the middle of the conveying frame 1, side pushing mechanisms for correcting glass crafts are arranged on both sides of the conveying frame 1, a mounting frame 2 is fixedly arranged on the top of the conveying frame 1, a lifting electric push rod 3 is fixedly arranged on the mounting frame 2, and a cutting mechanism is fixedly arranged on the output end of the lifting electric push rod 3; the conveying mechanism comprises a conveying motor 4, two conveying rollers 5, two conveying belts 6 and two supporting platforms 7, wherein the conveying motor 4 is fixedly arranged on the conveying frame 1 and is used to drive one of the conveying rollers 5 to rotate, the two conveying rollers 5 are both rotatably arranged on the conveying frame 1, the two conveying rollers 5 are connected by two conveying belts 6, there is a reserved gap between the two conveying belts 6, and the two supporting platforms 7 are respectively fixedly arranged on the conveying frame 1 and are respectively located on the inner sides of the two conveying belts 6;

[0033] With such a design, when in use, the plate-shaped glass crafts are conveyed by the conveying mechanism, specifically, the plate-shaped glass crafts are placed above the conveyor belt 6, and the conveying motor 4 drives the conveyor belt 6 to move through the conveyor roller 5, and the plate-shaped glass crafts are conveyed by the conveyor belt 6; in the process of conveying, firstly, the edges of the plate-shaped glass crafts are pushed sideways from both sides of the conveying frame 1 by two side pushing mechanisms to achieve position correction of the plate-shaped glass crafts, when the plate-shaped glass crafts pass through the cutting mechanism, the cutting mechanism is driven to descend by the lifting electric push rod 3, the plate-shaped glass crafts are cut by the cutting mechanism, and the plate-shaped glass crafts are fixed on the conveyor belt 6 by vacuum adsorption to improve the stability during transportation.

[0034] In order to solve the problem that the existing thick plate-shaped glass crafts have poor stability during the transportation process during the cutting process, and because the transportation of the glass crafts needs to be stopped during cutting, which increases the time used for the glass crafts cutting operation, the support table 7 is a hollow structure, and a vacuum pump 8 and a box body 9 are fixedly arranged inside the support table 7. A connecting port 10 is provided at the top of the support table 7, and a plurality of exhaust channels 11, a plurality of connecting holes 12, a plurality of annular grooves 13 and a plurality of exhaust holes 14 are provided on the conveyor belt 6. The air outlet end of the vacuum pump 8 is connected to the outside, and the air inlet end of the vacuum pump 8 is connected to the box body 9. The interior of the box body 9 is connected to the exhaust hole 14 through the connecting port 10, the exhaust channel 11, the connecting hole 12, and the annular groove 13 in turn, and a one-way air permeable valve is fixedly arranged inside each exhaust channel 11;

[0035] With such a design, during the transportation process, negative pressure suction is generated inside the box body 9 through the vacuum pump 8, and the negative pressure suction is transmitted to the suction hole 14 through the connecting port 10, the exhaust channel 11, the connecting hole 12, and the annular groove 13 in sequence, and the plate-shaped glass crafts are negatively adsorbed through the exhaust hole 14, so that the plate-shaped glass crafts maintain good stability during the transportation process, and because of the good stability, the plate-shaped glass crafts can be cut by the cutting mechanism during the transportation process, thereby reducing the time required for the cutting process.

[0036] A plurality of air extraction channels 11 are distributed along the circumference of the conveyor belt 6 and are located on the inner surface of the conveyor belt 6, and some of the air extraction channels 11 are connected to the connection port 10. The connection holes 12 are located inside the conveyor belt 6 and are connected to the air extraction channels 11 in a one-to-one correspondence. A plurality of annular grooves 13 are distributed along the width direction of the conveyor belt 6, and adjacent annular grooves 13 are connected through the connection holes 12. A plurality of air extraction holes 14 are distributed on the outer surface of the conveyor belt 6 and are connected to the corresponding annular grooves 13.

[0037] With this design, even if the conveyor belt 6 is constantly moving and the connecting port 10 is in a fixed position, since the exhaust channel 11 on the conveyor belt 6 is always partially connected to the connecting port 10, the normal transmission of the negative pressure suction force can be guaranteed; and when the exhaust channel 11 is separated from the area of ​​the connecting port 10, the one-way air valve can prevent the outside air from entering the exhaust channel 11 to ensure the vacuum pumping.

[0038] The inner surface of the conveyor belt 6 is connected with a plurality of integrated annular sliders 37, the cross-sectional shape of the annular slider 37 is T-shaped, and the top and bottom ends of the support platform 7 are provided with track grooves 38 that slide with the annular slider 37, wherein the bottom end of the air extraction channel 11 is located on the annular slider 37, and the connection port 10 is located inside the track groove 38;

[0039] Such a design, through the sliding sealing cooperation between the annular slider 37 and the track groove 38, can improve the stability of the conveyor belt 6 during movement on the one hand, and improve the sealing between the connecting port 10 and the corresponding exhaust channel 11 on the other hand.

[0040] The cutting mechanism includes a motor frame 15, a cutting motor 16 and a cutting knife 17, wherein the motor frame 15 is fixedly arranged on the output end of the lifting electric push rod 3, the cutting motor 16 is fixedly arranged on the motor frame 15, and the cutting knife 17 is fixedly arranged on the output shaft of the cutting motor 16;

[0041] With this design, the cutting motor 16 drives the cutting knife 17 to rotate, and the lifting and lowering of the lifting electric push rod 3 are coordinated to enable the cutting knife 17 to perform cutting operations.

[0042] In the process of correcting the plate-shaped glass craftwork, in order to further improve the correction effect, the side push mechanism includes two side push members, a side push frame 19, two belt rollers 20 and a side belt body 21, wherein the two side push members are fixedly arranged on the conveying frame 1, the side push frame 19 is arranged between the two side push members, the two belt rollers 20 are rotatably arranged on the side push frame 19, and the two belt rollers 20 are connected by the side belt body 21;

[0043] In this design, the side push member drives the side push frame 19 to move, and the side push frame 19 drives the side belt body 21 thereon to approach and abut against the edge of the glass craft. Since the side belt body 21 can rotate along the belt roller 20, the position of the glass craft can be adjusted by the side belt body 21 even when the conveyor belt 6 is moving.

[0044] The side push member includes a side electric push rod 22 and a side bracket 23. The side electric push rod 22 is fixedly arranged on the conveying frame 1. The side bracket 23 is fixedly arranged on the output end of the side electric push rod 22. A T-shaped rod 24 is relatively slidably arranged in the rod hole on the side bracket 23. A support spring 25 surrounds the T-shaped rod 24. The support spring 25 is located above the side bracket 23, and the T-shaped rod 24 is fixedly arranged with the side push frame 19.

[0045] In this design, since the T-shaped rod 24 can move in the vertical direction, when the glass craft needs to move in the vertical direction during adjustment, the position adjustment operation of the glass craft can still be continued.

[0046] In order to reduce the friction between the glass craft and the conveyor belt 6 when the position is corrected, so as to facilitate the small-range movement of the glass craft, the air extraction hole 14 is T-shaped, and a support is movably provided inside the air extraction hole 14. A telescopic spring 26 and a magnetic block 27 are provided on one end of the annular groove 13 of the support, and an electromagnet 28 is fixedly provided at one end of the support platform 7, and the electromagnet 28 and the magnetic block 27 are arranged to repel each other magnetically;

[0047] With this design, when it is needed to correct the position of the glass craft on the conveyor belt 6, the electromagnet 28 generates magnetism through its operation. Under the action of the magnetic force, the magnetic block 27 drives the support member to move upward in the air extraction hole 14, so that the support member partially extends out of the air extraction hole 14 to support the glass craft, thereby reducing the resistance encountered by the glass craft during adjustment by reducing the contact area. When the position of the glass craft is corrected, the long strip electromagnet 28 no longer works. At this time, under the action of the weight of the glass craft, it falls to the surface of the conveyor belt 6. Because of the fixation of the telescopic spring 26 and the side belt body 21, the glass craft will fall to the surface of the conveyor belt 6 relatively smoothly and with the adjusted position unchanged, thereby ensuring the accuracy of the position correction of the glass craft.

[0048] In order to further improve the stability of the glass crafts during the conveying and cutting processes, the support member is a support rod 29, the shape of the support rod 29 is an I-shaped, and the interior of the support rod 29 is provided with a mounting groove 30, a sliding groove 31 and a side connecting groove 32 from top to bottom, the mounting groove 30 is connected with the side connecting groove 32 through the sliding groove 31, wherein a suction cup 33 is arranged in the mounting groove 30, a sliding tube 34 is fixedly arranged on the suction cup 33, and the sliding tube 34 is slidably matched with the sliding groove 31, a through groove 35 is also arranged at the top of the support rod 29, and a receiving groove 36 is arranged inside the exhaust hole 14, and the receiving groove 36 is fixed to the suction cup 33 through the connecting spring 18, and the connecting spring 18 and the through groove 35 are relatively penetrated;

[0049] With this design, when the support rod 29 supports the glass craft under the action of magnetic force, the suction cup 33 is stored in the installation groove 30 and does not contact the glass craft, thereby reducing the obstruction of the glass craft when adjusting. When the magnetic force disappears and the support rod 29 moves down and is stored in the exhaust hole 14, the support rod 29 abuts against the glass craft under the action of the telescopic spring 26, and the suction cup 33 also abuts against the glass craft under the action of the connecting spring 18. At the same time, the side groove 32 moves down and communicates with the annular groove 13. Subsequently, the suction force in the annular groove 13 can be transmitted to the inside of the suction cup 33 through the side groove 32, the sliding groove 31, and the sliding tube 34 in sequence by vacuum adsorption, thereby further improving the stability of the glass craft transportation.

[0050] Specifically, the sliding tube 34 is T-shaped, and the middle radius of the sliding groove 31 is larger than the top and bottom radii thereof; such a design can prevent the sliding tube 34 from being separated from the inside of the sliding groove 31 .

[0051] Working principle:

[0052] S1, firstly, the glass craft is placed at one end of the conveyor frame 1, and the electromagnet 28 is energized to generate magnetic force, and the magnetic repulsion of the magnetic block 27 is coordinated to make the support rod 29 located above the electromagnet 28 on the conveyor belt 6 move upward, and the glass craft is lifted upward by the support rod 29 to reduce the effective contact area of ​​the glass craft, so that the resistance of the glass craft is smaller when fine-tuning; if it is necessary to explain, the glass craft can be placed when the conveyor belt 6 is stopped or conveyed, and it can be set according to the actual situation;

[0053] S2, then push the edge of the glass craft from both sides through two side push mechanisms to correct the position of the glass craft so that its edge is parallel to the edge of the conveyor frame 1. The specific process is as follows:

[0054] The side push frame 19 at the end thereof is driven to move by the lateral electric push rod 22, so that the side belt body 21 on the side push frame 19 abuts against the edge of the glass craft, and the position of the glass craft is finely adjusted by the side belt body 21 in the two side push mechanisms. Since the side belt body 21 can be driven by the friction force of the glass craft, the position of the glass craft can be corrected during the conveying process of the conveyor belt 6;

[0055] S3, after the position correction is completed, the electromagnet 28 is powered off to eliminate the magnetic force. Since the side push frame 19 can slide in the vertical direction, the support rod 29 is compressed under the weight of the glass craft and slides downward in the air extraction hole 14 to squeeze the telescopic spring 26, so that the side connection groove 32 on the support rod 29 enters the annular groove 13 and is connected. Under the action of the telescopic spring 26 and the connecting spring 18, the top of the support rod 29 and the suction cup 33 therein are in contact with the glass craft.

[0056] S4, then the vacuum pump 8 generates negative pressure suction inside the box body 9, and the negative pressure suction is transmitted to the annular groove 13 through the connecting port 10, the exhaust channel 11, and the connecting hole 12 in sequence, and then transmitted to the inside of the suction cup 33 through the annular groove 13, the side groove 32, the sliding groove 31, and the sliding tube 34, so that the suction cup 33 fixes the glass craft by vacuum adsorption, and then the glass craft can be transported with good stability through the conveyor belt 6;

[0057] S5, when the glass craft passes under the mounting frame 2 and reaches the area to be cut, the cutting mechanism is driven to move by the lifting electric push rod 3, so that the cutting knife 17 in the cutting mechanism rotates to cut the glass craft;

[0058] S6, after the cutting is completed, when the glass craft leaves the cutting area, the vacuum pump 8 is turned off. At this time, due to the disappearance of power, the suction cup 33 no longer plays the role of adsorbing and fixing the glass craft. The staff can take the cut glass craft off from the other end of the conveying frame 1, or convey the cut glass craft to the conveying equipment of the next process through the conveyor belt 6, thereby completing the cutting operation.

[0059] It should be noted that, in the area of ​​the conveyor belt 6 that does not contact the glass craftwork, under the action of the telescopic spring 26, the support rod 29 extends out of the exhaust hole 14, so that the side groove 32 moves into the exhaust hole 14 and is no longer connected to the annular groove 13, so as to ensure vacuuming.

[0060] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
