Description

Technical Field

[0001] The 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 take pictures of relevant parts of the glass and compare the pictures with the target pictures to determine whether the quality of the current glass is qualified. If unqualified glass is identified, in the prior art, it is usually necessary to temporarily shut down the conveyor line to stop the defective glass from moving forward, and then use a robot to remove the defective glass from the production line and put it on the reflow conveyor line to return 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 in parallel horizontally will seriously occupy the floor space in the workshop; if the return conveyor line and the production conveyor line are arranged in parallel vertically, a space for the robot to transfer the glass pieces needs to be reserved on one side of the production line, which will also occupy a lot of space in the workshop.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figure 1 - Figure 7 and Fig. 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 conveying rollers 102 arranged at uniform intervals; 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 reflow rollers 202 arranged at uniform intervals; under normal use, the glass sheet is 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, the material taking mechanism 300 is arranged between the conveying mechanism 100 and the reflux mechanism 200, and the material taking mechanism 300 is used to transfer the glass sheet on the conveying mechanism 100 to the reflux mechanism 200; in addition, there is a material taking gap between the plurality of conveying rollers 102, and the material taking gap is located directly above the material taking mechanism 300, and a plurality of material taking rollers 400 are arranged in the material taking gap, and the plurality of material taking rollers 400 and the plurality of conveying rollers 102 are arranged in a uniformly spaced arrangement, and the length of the material taking rollers 400 can be extended to allow the glass sheet to pass through the material taking gap. Specifically, the conveying mechanism 100 also includes a driving assembly (not shown in the figure), and the driving assembly is used to drive the conveying roller 102 and the material taking roller 400 to rotate together, and the material taking roller 400 and the conveying roller 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 feeding plate 302 is provided on the top of the feeding frame 301. The feeding plate 302 is an internal hollow structure. A plurality of suction cups 303 are provided on the top surface of the feeding plate 302. The suction cups 303 are communicated with the inside of the feeding plate 302. An air extraction pipe 304 is also provided on the side wall of the feeding plate 302. The air extraction pipe 304 is connected to an external air source through a hose. The external air source can be a vacuum pump. When the suction cups 303 are attached to the glass sheet and the external air source draws the inside of the feeding plate 302 into a negative pressure state, the suction cups 303 can absorb the glass sheet.

[0041] Furthermore, both ends of the material taking plate 302 are provided with rotating shafts, and the two rotating shafts are respectively rotatably connected to the two side walls of the material taking frame 301, and a servo motor 305 is provided on one side wall of the outer side of the material taking frame 301, and the output shaft of the servo motor 305 is fixedly connected to one of the rotating shafts. That is, the servo motor 305 can directly control the rotation of the material taking 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 respectively located at the front and rear sides of the material taking frame 301, and the two support frames 306 are fixedly connected to the conveying frame 101 and the return frame 201. The facing surfaces of the two support frames 306 are provided with slide cylinders 307, and the movable ends of the two slide cylinders 307 are respectively fixedly connected to the front and rear side walls of the material taking frame 301. The support frames 306 pass between two adjacent return rollers 202, and the slide cylinders 307 are distributed vertically to directly control the lifting and lowering of the material taking 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 surface of the conveying frame 101 and located at the material taking gap. Figure 7As shown, a driving motor 104 is provided on the stabilizing frame 103, and a stabilizing rod 105 is coaxially connected to the output shaft of the driving motor 104. A universal ball 106 is provided on the bottom surface of the free end of the stabilizing rod 105; when the stabilizing rod 105 rotates to be parallel to the conveying roller 102, the universal ball 106 is used to abut against the upper surface of the glass sheet. In the initial state, the stabilizing rod 105 and the conveying roller 102 remain perpendicular, and the glass sheet is located between the two stabilizing frames 103, so the stabilizing rod 105 will not affect the normal passage of the glass sheet; when the defective glass sheet is transported between the two stabilizing frames 103, the conveying roller 102 and the material-taking roller 400 temporarily stop rotating, and the driving motor 104 drives the stabilizing rod 105 to rotate 90 degrees, so that the universal ball 106 abuts against 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 material taking roller 400 includes two outer sleeves 401, which are rotatably connected to the front and rear side walls of the conveying frame 101 respectively, and the two outer sleeves 401 are arranged with the same central axis, an inner sleeve 402 is inserted into the inner part of the outer sleeve 401, and the inner sleeve 402 and the outer sleeve 401 are axially slidably matched, a plug 403 is provided at the inner end of the inner sleeve 402, and a blocking ring 404 is provided at the open end of the outer sleeve 401 to prevent the plug 403 from falling off, and a push spring 405 is connected between the plug 403 and the inner end of the outer sleeve 401; in a natural state, the push spring 405 is in a compressed state, and there is a small gap between the two inner sleeves 402. The inner diameter of the blocking ring 404 is smaller than the diameter of the plug 403, so the blocking ring 404 can prevent 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 axial direction, 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 that can be attracted by the electromagnet 406 is provided at the inner end surface of the plug 403; when the electromagnet 406 is energized, the electromagnet 406 and the iron block 407 fit each other, and the outer end of the inner sleeve 402 is retracted into the outer sleeve 401. That is, the adsorption force of the electromagnet 406 on the iron block 407 is greater than the thrust of the push spring 405, and when the electromagnet 406 is energized, the electromagnetic force can overcome the elastic force to attract the inner sleeve 402 to slide toward the electromagnet 406.

[0047] In addition, there are four feeding rollers 400, two of which are arranged on the left and right sides of the feeding mechanism 300, a power supply 308 is arranged on the feeding frame 301, and two conductive rods 309 are arranged on one side of the feeding frame 301, and the two conductive rods 309 are respectively connected to the positive and negative electrodes of the power supply 308; two first conductive contact sheets 310 are arranged on the top of one of the support frames 306, and two second conductive contact sheets 311 are arranged 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 side 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, the first conductive contacts 310 and the second conductive contacts 311 are all made of copper.

[0048] In summary, the material picking mechanism 300 is located in the middle of the four material picking rollers 400. In the initial state, the material picking frame 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 material picking gap position, the conveying roller 102 and the material picking roller 400 temporarily stop rotating, and the driving motor 104 drives the stabilizing rod 105 to rotate to be parallel to the material picking roller 400 to press the glass sheet, and the slide cylinder 307 will control the material picking frame 301 to rise, and 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 taking rack 301, the conductive rod 309 first contacts the second conductive contact sheet 311, then contacts the first conductive contact sheet 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 feeding rollers 400 on the right side of the feeding mechanism 300 are powered on, so that the inner sleeve 402 is retracted into the outer sleeve 401, and the right side of the glass sheet is suspended. Then, the servo motor 305 controls the feeding plate 302 to rotate 90° clockwise, so that the glass sheet is in a vertical state.

[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 sheet 311, and the slide cylinder 307 temporarily stops moving. At this time, the electromagnets 406 in the two material picking rollers 400 on the left side of the material picking mechanism 300 are powered on, and the inner sleeve 402 is retracted into the outer sleeve 401. However, the servo motor 305 controls the glass sheet to rotate 90° counterclockwise to restore the horizontal state. Figure 3 Status shown.

[0051] Finally, the slide cylinder 307 controls the material taking frame 301 to continue to descend until the glass sheet contacts the reflow roller 202, and then the suction cup 303 releases the glass sheet, allowing the glass sheet 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 spacing between the two outer sleeves 401, and the glass sheet is always located in the middle of the conveying roller 102. When the glass sheet is conveyed to the material taking roller 400, the glass sheet is just located on the two inner sleeves 402; in addition, the spacing between the conveying roller 102 and the reflow roller 202 in the vertical direction is slightly greater than half of the length of the glass sheet, which helps to reduce the space occupied by the device.

[0052] Example 2: Please refer to Figure 1 - Fig.10 The embodiment of the present application provides a glass sheet reflow device on 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 provided with a plurality of annular grooves 408 arranged at intervals, and a plurality of guide posts 409 are provided in the annular grooves 408. The guide posts 409 are movable and penetrate the annular grooves 408. The guide posts 409 are distributed along the radial direction of the inner sleeve 402. The outer ends of the guide posts 409 are provided with arc pieces 410, and the outer parts of the plurality of arc pieces 410 are collectively sleeved with an elastic sleeve 411. It should be noted that the plurality of arc pieces 410 together form a circular shape with multiple gaps, and the elastic sleeve 411 is made of silicone material, which is elastic and has a large surface friction coefficient. The inner surface of the elastic sleeve 411 always fits the outer surface of the arc piece 410. The function of the elastic sleeve 411 is to avoid rigid collision between the glass sheet and the inner sleeve 402, and at the same time, it is used to drive the glass sheet to move and prevent slipping. When the plurality of arc pieces 410 move synchronously along the radial direction of the inner sleeve 402, the diameter of the elastic sleeve 411 can be adjusted to make the elastic sleeve 411 extend out or retract into the annular groove 408.

[0054] The inner sleeve 402 is provided with a shaft 412 distributed along its axial direction, and the inner end of the guide column 409 is hinged with a diagonal support rod 413, and the end of the diagonal support rod 413 away from the guide column 409 is hinged with the shaft 412. In this embodiment, when the shaft 412 moves toward the plug 403, the guide column 409 extends outward, thereby expanding the diameter of the elastic sleeve 411; conversely, when the shaft 412 moves toward the side away from the plug 403, the diameter of the elastic sleeve 411 will be reduced.

[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 a 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 reset 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, and causing a plurality of 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 reset 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 into the outer sleeve 401, since the elastic sleeve 411 is retracted into the annular groove 408, the elastic sleeve 411 will not generate friction with the bottom surface of the glass sheet, and it is also avoided to leave marks on the bottom surface of the glass sheet.

[0058] It should be noted that, in this article, the terms "include", "comprises" or any other variations 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 includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0059] 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.
