Description

Technical Field

[0001] The present invention relates to the technical field of glass production lines, in particular to a glass sheet reflow device on a glass production line. Background Art

[0002] During the production process, glass needs to go through multiple processes such as melting, forming, annealing, cutting, cleaning, inspection and packaging. Between different processes, it is generally transported through production conveyor lines to improve production efficiency and save human resources.

[0003] Glass production lines are usually equipped with inspection mechanisms to check the quality of glass from the previous process to prevent defective glass from flowing into the next process and causing waste of resources. Common inspection mechanisms include visual cameras, which capture images of relevant parts of the glass and compare them with target images to determine whether the current glass is of acceptable quality. If unqualified glass is identified, the existing technology usually requires temporarily shutting down the conveyor line to stop the defective glass from moving forward. The defective glass is then removed from the production line using a robotic arm and placed on the reflow conveyor line, returning it to the previous process so that the workers in the previous process can confirm and rework it.

[0004] However, arranging the return conveyor line and the production conveyor line horizontally side by side would significantly occupy the floor space within the workshop. If the return conveyor line and the production conveyor line are arranged vertically side by side, space would need to be reserved on one side of the production line for the robot to transfer the glass sheets, which would also occupy a large amount of workshop space. In view of this, we have proposed a glass sheet reflow device for glass production lines to effectively address the above drawbacks. Summary of the Invention

DETAILED DESCRIPTION

[0036] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figure 1 - Figure 7 and Figure 9 The embodiment of the present application provides a glass sheet reflow device on a glass production line, comprising a conveying mechanism 100, a reflow mechanism 200 and a material taking mechanism 300, wherein the conveying mechanism 100 comprises a conveying frame 101 and a plurality of evenly spaced conveying rollers 102; the reflow mechanism 200 is arranged directly below the conveying mechanism 100, and the reflow mechanism 200 comprises a reflow frame 201 and a plurality of evenly spaced reflow rollers 202; in normal use, the glass sheets are conveyed by the plurality of conveying rollers 102, and the reflow mechanism 200 is used to convey unqualified glass sheets back to the starting end position of the conveying mechanism 100, so the conveying directions of the conveying mechanism 100 and the reflow mechanism 200 are opposite.

[0038] In the embodiment of the present application, a pick-up mechanism 300 is disposed between the conveying mechanism 100 and the reflow mechanism 200. The pick-up mechanism 300 is used to transfer glass sheets from the conveying mechanism 100 to the reflow mechanism 200. In addition, a pick-up gap is defined between the plurality of conveying rollers 102. The pick-up gap is located directly above the pick-up mechanism 300. Within the pick-up gap are a plurality of pick-up rollers 400. The pick-up rollers 400 and the plurality of conveying rollers 102 are arranged in a uniformly spaced arrangement. The length of the pick-up rollers 400 is retractable to allow glass sheets to pass through the pick-up gap. Specifically, the conveying mechanism 100 further includes a drive assembly (not shown) that is used to drive the conveying rollers 102 and the pick-up rollers 400 to rotate together. Furthermore, the pick-up rollers 400 and the conveying rollers 102 are located on the same horizontal plane.

[0039] The structure of the material taking mechanism 300 is described in detail below:

[0040] The material taking mechanism 300 includes an I-shaped material taking frame 301, such as Figure 5 As shown, a retrieving plate 302 is provided on top of the retrieving rack 301. The retrieving plate 302 has a hollow interior and is provided with a plurality of suction cups 303 on its top surface. The suction cups 303 communicate with the interior of the retrieving plate 302. An air extraction pipe 304 is also provided on the side wall of the retrieving plate 302. The air extraction pipe 304 is connected to an external air source via a flexible tube. The external air source can be a vacuum pump. When the suction cups 303 are in contact with the glass sheet and the external air source creates a negative pressure inside the retrieving plate 302, the suction cups 303 can then absorb the glass sheet.

[0041] Furthermore, both ends of the reclaiming plate 302 are provided with rotating shafts, which are rotatably connected to the two side walls of the reclaiming frame 301. A servo motor 305 is provided on one side wall of the reclaiming frame 301, and the output shaft of the servo motor 305 is fixedly connected to one of the rotating shafts. In other words, the servo motor 305 can directly control the rotation of the reclaiming plate 302.

[0042] On the other hand, the material taking mechanism 300 further includes two support frames 306, such as Figure 5 As shown, two support frames 306 are located on the front and rear sides of the reclaiming frame 301, respectively. Both support frames 306 are fixedly connected to the conveying frame 101 and the return frame 201. Slide cylinders 307 are installed on the facing surfaces of the two support frames 306. The movable ends of the two slide cylinders 307 are fixedly connected to the front and rear side walls of the reclaiming frame 301. The support frames 306 pass between two adjacent return rollers 202. The slide cylinders 307 are distributed vertically and are used to directly control the raising and lowering of the reclaiming frame 301.

[0043] In the embodiment of the present application, a stabilizing frame 103 is provided on both the front and rear sides of the top of the conveying frame 101 and located at the material taking gap. Figure 7As shown, a drive motor 104 is mounted on the stabilizing frame 103. The output shaft of the drive motor 104 is coaxially connected to a stabilizing rod 105. A universal ball 106 is mounted on the bottom surface of the free end of the stabilizing rod 105. When the stabilizing rod 105 rotates parallel to the conveyor rollers 102, the universal ball 106 contacts the top surface of the glass sheet. In the initial state, the stabilizing rod 105 and the conveyor rollers 102 remain perpendicular, and the glass sheet is positioned between the two stabilizing frames 103. Therefore, the stabilizing rod 105 does not affect the normal passage of the glass sheet. When a defective glass sheet is transported between the two stabilizing frames 103, the conveyor rollers 102 and the pick-up roller 400 temporarily stop rotating, while the drive motor 104 drives the stabilizing rod 105 to rotate 90 degrees, causing the universal ball 106 to contact the top surface of the glass sheet, thereby maintaining the stability of the glass sheet.

[0044] The structure of the take-up roller is described in detail below:

[0045] The retrieving roller 400 includes two outer sleeves 401, which are rotatably connected to the front and rear side walls of the conveyor frame 101, respectively. The two outer sleeves 401 are arranged coaxially. An inner sleeve 402 is inserted into the outer sleeve 401, and the inner sleeve 402 and the outer sleeve 401 slide together along the axial direction. The inner end of the inner sleeve 402 is provided with a plug 403, and the open end of the outer sleeve 401 is provided with a sealing ring 404 to prevent the plug 403 from falling off. A push spring 405 is connected between the plug 403 and the inner end of the outer sleeve 401. In its natural state, the push spring 405 is compressed, and a small gap exists between the two inner sleeves 402. The inner diameter of the sealing ring 404 is smaller than the diameter of the plug 403, thereby preventing the plug 403 from falling off. In addition, the inner wall of the outer sleeve 401 is provided with a slide rail distributed along its own axis, and the plug 403 slides in cooperation with the slide rail. Under the pushing action of the push spring 405, when the plug 403 is not affected by external force of the system, the plug 403 is always located close to the side of the sealing ring 404.

[0046] Furthermore, an electromagnet 406 is provided at the inner end of the outer sleeve 401, and an iron block 407 is provided on the inner end surface of the plug 403, which is attracted by the electromagnet 406. When the electromagnet 406 is energized, the electromagnet 406 and the iron block 407 fit together, and the outer end of the inner sleeve 402 retracts into the outer sleeve 401. In other words, the attraction force of the electromagnet 406 on the iron block 407 is greater than the thrust of the spring 405. When the electromagnet 406 is energized, the electromagnetic force overcomes the spring force, causing the inner sleeve 402 to slide toward the electromagnet 406.

[0047] In addition, there are four feeding rollers 400, two of which are provided on the left and right sides of the feeding mechanism 300, a power supply 308 is provided on the feeding frame 301, and two conductive rods 309 are provided on one side of the feeding frame 301, and the two conductive rods 309 are respectively connected to the positive and negative poles of the power supply 308; two first conductive contact pieces 310 are provided on the top of one of the support frames 306, and two second conductive contact pieces 311 are provided in the middle of the support frame 306, which are located on the right side of the feeding mechanism 300. The two leads of the electromagnet 406 on the left side of the material picking mechanism 300 are respectively connected to the two first conductive contacts 310, and the two leads of the electromagnet 406 on the left side of the material picking mechanism 300 are respectively connected to the two second conductive contacts 311. When the two conductive rods 309 are respectively in contact with the two first conductive contacts 310, the top surface of the suction cup 303 is at the same height as the material picking roller 400; when the two conductive rods 309 are respectively in contact with the two second conductive contacts 311, the top surface of the suction cup 303 is lower than the material picking roller 400. It should be noted that the material picking frame 301 and the support frame 306 are both made of insulating materials, while the conductive rods 309 and the first and second conductive contacts 310, 311 are all made of copper.

[0048] In summary, the picking mechanism 300 is located in the middle of the four picking rollers 400. In the initial state, the picking rack 301 is located at the bottom side of the support frame 306. When the external inspection mechanism detects a defective glass sheet, when the defective glass sheet stays at the picking gap position, the conveying roller 102 and the picking roller 400 temporarily stop rotating, and the drive motor 104 drives the stabilizing rod 105 to rotate parallel to the picking roller 400 to press the glass sheet, and the slide cylinder 307 will control the picking rack 301 to rise. Synchronously, the external air source will also be started to form a negative pressure environment in the suction cup 303.

[0049] During the rising process of the material rack 301, the conductive rod 309 first contacts the second conductive contact piece 311, then contacts the first conductive contact piece 310 and then stops. At this time, the suction cup 303 is in contact with the bottom surface of the glass sheet. Figure 1 In the state shown, the electromagnets 406 in the two pick-up rollers 400 on the right side of the pick-up mechanism 300 are both energized, causing the inner sleeves 402 to retract into the outer sleeves 401, leaving the right side of the glass sheet suspended. The servo motor 305 then controls the pick-up plate 302 to rotate 90° clockwise, placing the glass sheet in a vertical position.

[0050] After the glass is rotated 90°, Figure 2In the state shown, the slide cylinder 307 continues to control the material picking rack 301 to move downward until the conductive rod 309 contacts the second conductive contact 311, at which point the slide cylinder 307 temporarily stops moving. At this point, the electromagnets 406 in the two material picking rollers 400 on the left side of the material picking mechanism 300 are both energized and activated, and the inner sleeve 402 is retracted into the outer sleeve 401. The servo motor 305 then controls the glass sheet to rotate 90° counterclockwise to restore it to a horizontal state. Figure 3 Status shown.

[0051] Finally, the slide cylinder 307 controls the pick-up rack 301 to continue descending until the glass sheet contacts the reflow roller 202. The suction cup 303 then releases the glass sheet, allowing it to reflow under the action of the reflow roller 202. It should be noted that in this embodiment, the width of the glass sheet is less than the distance between the two outer sleeves 401, and the glass sheet is always located in the middle of the conveyor rollers 102. When the glass sheet is conveyed to the pick-up roller 400, it is exactly located on the two inner sleeves 402. Furthermore, the vertical distance between the conveyor roller 102 and the reflow roller 202 can be slightly greater than half the length of the glass sheet, which helps to reduce the space occupied by the device.

[0052] Example 2: Please refer to Figure 1 - Figure 10 The present embodiment of the present application provides a glass sheet reflow device for a glass production line. The difference between this embodiment and the first embodiment is that:

[0053] The outer surface of the inner sleeve 402 is defined by a number of spaced annular grooves 408. Within these grooves are several guide posts 409, which flexibly extend through the grooves 408 and are distributed radially along the inner sleeve 402. Curved pieces 410 are located at their outer ends, and an elastic sleeve 411 is positioned over the outer surfaces of these curved pieces 410. It should be noted that these curved pieces 410 collectively form a circular shape with multiple gaps. The elastic sleeve 411 is made of elastic silicone, which offers a high coefficient of friction. The inner surface of the elastic sleeve 411 consistently conforms to the outer surface of the curved pieces 410. The elastic sleeve 411 prevents rigid collisions between the glass sheet and the inner sleeve 402 and also serves to drive the glass sheet's movement, preventing slippage. As the curved pieces 410 move synchronously along the radial direction of the inner sleeve 402, the diameter of the elastic sleeve 411 can be adjusted to allow it to extend or retract within the annular groove 408.

[0054] The inner sleeve 402 is provided with a shaft 412 extending along its axial direction. A diagonal support rod 413 is hingedly connected to the inner end of the guide post 409. The end of the diagonal support rod 413, which is away from the guide post 409, is hingedly connected to the shaft 412. In this embodiment, when the shaft 412 moves toward the plug 403, the guide post 409 extends outward, thereby expanding the diameter of the elastic sleeve 411. Conversely, when the shaft 412 moves away from the plug 403, the diameter of the elastic sleeve 411 decreases.

[0055] Furthermore, the interior of the plug 403 is a hollow structure, one end of the shaft 412 passes through the plug 403 and is provided with a movable pressure cover 414, a return spring 415 is connected between the side of the movable pressure cover 414 facing away from the shaft 412 and the inner wall of the plug 403, and the side of the movable pressure cover 414 facing the shaft 412 is also provided with a push column 416, the outer end of the push column 416 passes through the plug 403 and extends to the outside of the plug 403; in the natural state, the push column 416 abuts against the sealing ring 404, and the outer surface of the elastic sleeve 411 protrudes from the outer surface of the inner sleeve 402; when the push column 416 does not abut against the sealing ring 404, the elastic sleeve 411 retracts into the annular groove 408.

[0056] Specifically, the elastic force of the return spring 415 is smaller than the elastic force of the push spring 405. When the push spring 405 pushes the plug 403 close to the sealing ring 404, the sealing ring 404 can push the push column 416 into the inner side of the plug 403, thereby causing the shaft rod 412 to move toward the side of the outer sleeve 401, causing several guide columns 409 to extend outward, thereby expanding the diameter of the elastic sleeve 411; conversely, when the inner sleeve 402 retracts inward into the outer sleeve 401, due to the loss of the obstruction of the sealing ring 404, under the action of the return spring 415, the shaft rod 412 will move toward the side away from the outer sleeve 401, causing the elastic sleeve 411 to retract into the annular groove 408.

[0057] Therefore, in actual application of this embodiment, when the inner sleeve 402 is retracted inwardly into the outer sleeve 401, the elastic sleeve 411 will retract into the annular groove 408. Therefore, the elastic sleeve 411 will not generate friction with the bottom surface of the glass sheet, and will avoid leaving marks on the bottom surface of the glass sheet.

[0058] It should be noted that, in this document, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0059] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
