Description

Technical Field

[0001] This invention relates to the field of laminated glass production equipment, and particularly to a continuous laminated glass vacuum production apparatus. Background Technology

[0002] Laminated glass is a composite glass product made of two or more sheets of glass with one or more layers of organic polymer interlayer sandwiched between them. After a special high-temperature prefabrication (or vacuum) and high-temperature, high-pressure process, the glass and interlayer are permanently bonded together. Even if laminated glass breaks, the fragments will adhere to the interlayer film, and the broken glass surface remains clean and smooth. This effectively prevents injuries from glass shards and falls, ensuring personal safety.

This equipment has a built-in device for positioning lower glass plates of different thicknesses and sizes, accurately cutting the film according to the glass dimensions, and precisely pressing the upper glass plate onto the lower glass plate according to its position. The operation is simple, and the lamination position is accurate.

[0004] However, in actual use, when the above-mentioned patent is applied to cover the lower glass sheet and then the upper glass sheet is covered, it is still necessary to manually lift the glass. After the laminated glass is assembled, it is also necessary to lift the assembled laminated glass down for subsequent processing.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0034] Embodiment One

[0035] As shown in Figure 1 and Figure 2 , the embodiment discloses a continuous laminated glass vacuum production device, which comprises two parallel glass sheet conveying lines 1, a rack 2 is arranged above the two glass sheet conveying lines 1, two vertical grabbing devices 3 for grabbing glass sheets are symmetrically and fixedly installed at the upper end of the rack 2, a film mounting frame 4 is arranged at the middle of the upper end of the rack 2 and located between the two vertical grabbing devices 3, and an auxiliary conveying frame 5 for assisting in conveying laminated glass is fixedly installed between the two glass sheet conveying lines 1.

[0036] It should be noted that the glass sheet conveying line 1 in the embodiment can adopt a conventional design in the prior art, which aims to convey the glass sheets to be laminated to the lower side of the vertical grabbing device 3 for grabbing by the vertical grabbing device 3, so that the subsequent work can be normally carried out.

[0037] In addition, please refer to Figure 1 and Figure 2In the embodiment, the outer surface of the conveying belt in the glass sheet conveying line 1 is also equidistantly fixed with a plurality of positioning assemblies for limiting the position of the glass plate. Each of the positioning assemblies is composed of two mutually perpendicular limiting rubber strips 11, and the positioning assemblies on the two glass sheet conveying lines 1 are arranged in axial symmetry, so that the glass sheet grabbed by the vertical grabbing device 3 each time is in the same position and can be aligned when the glass sheets are combined.

[0038] Further, as shown in Figure 3 , the rack 2 comprises two side racks 21 fixedly installed on the two sides of the two glass sheet conveying lines 1 for supporting the entire rack 2. The upper ends of the two side racks 21 are jointly fixedly installed with a horizontal rack 22. The upper ends of the horizontal rack 22 are symmetrically fixedly installed with two fixed racks 23 on the two sides. The two fixed racks 23 are used for fixing the two vertical grabbing devices 3. The two fixed racks 23 are fixedly connected with the two vertical grabbing devices 3. The film mounting rack 4 comprises two mutually parallel vertical plates 41 fixedly installed on the upper middle part of the horizontal rack 22 and located between the two fixed racks 23. The upper parts of the two vertical plates 41 are jointly rotatably installed with a central shaft 42. The outer surface of the central shaft 42 is sleeved with a film roller 43, and the film roller 43 is located between the two vertical grabbing devices 3. In the embodiment, the film roller 43 is used for winding the film, and the vertical grabbing devices 3 on the two sides are used for grabbing the glass sheets and clamping the glass sheets on the two sides of the film, so as to facilitate subsequent combination of the glass sheets.

[0039] Further, as shown in Figure 4 , Figure 5 , Figure 6 , the vertical grabbing device 3 comprises a fixed wall 31 vertically installed on the upper end of the horizontal rack 22 through the fixed rack 23. The rear end of the fixed wall 31 is fixedly installed with a driving motor 32. The driving motor 32 can be a conventional stepping motor in the prior art. The front end of the fixed wall 31 is provided with a rotating rod 34 fixedly connected with the output end of the driving motor 32. The rotating rod 34 is provided with a sliding groove 33. The front end of the fixed wall 31 is fixedly installed with a profile rail 35 on the outer side. The profile rail 35 is slidably installed with a ring-shaped bearing 36. The side of the ring-shaped bearing 36 away from the fixed wall 31 is provided with a movable shaft 37. The front end of the fixed wall 31 is also rotatably installed with a fixed rotating shaft 30. The end of the fixed rotating shaft 30 away from the fixed wall 31 is fixedly installed with a limiting sliding block 301. The limiting sliding block 301 is slidably installed with a mounting arm 38. The end of the mounting arm 38 away from the fixed wall 31 is rotatably connected with the mounting arm 38 through the sliding groove 33. The end of the mounting arm 38 is fixedly installed with a suction disc rack 302. The end of the suction disc rack 302 away from the fixed wall 31 is arrayed with a plurality of pneumatic suction discs 303.

[0040] In this embodiment, the outer ring of the ring bearing 36 is slidably connected to the groove opened on the irregular rail 35, and the inner ring of the ring bearing 36 is fixedly connected to the outer surface of the movable shaft 37. At the same time, wear-resistant layers can be provided on the contact surfaces of the ring bearing 36 and the ring bearing 36. Of course, in this embodiment, wear-resistant layers can also be provided on the contact surfaces of the movable shaft 37 and the slide groove 33 to increase the service life of the entire device.

[0041] In addition, it should be noted that the irregular-shaped rail 35 is composed of an arc-shaped rail 351 and straight rail 1 352 and straight rail 2 353 located at both ends of the arc-shaped rail 351. The arc-shaped rail 351, straight rail 1 352 and straight rail 2 353 are integrally formed, with high overall connection strength. The connection between the arc-shaped rail 351 and straight rail 1 352 and between the arc-shaped rail 351 and straight rail 2 353 is provided with an arc-shaped transition. Straight rail 1 352 is perpendicular to straight rail 2 353, and the perpendicular foot of the straight line where straight rail 1 352 and straight rail 2 353 are located coincides with the axis of the fixed rotating shaft 30. The center of the circle where the arc-shaped rail 351 is located also coincides with the axis of the fixed rotating shaft 30.

[0042] Based on the above, the specific implementation scenario of this embodiment is as follows:

[0043] Now assume Figure 1 The working state shown is the initial state. At this time, the mounting arm 38 is in a horizontal state, and the annular bearing 36 is located in the straight rail 353. Before use, first pull the film wound on the film roller 43 downwards a certain distance. Then, when the drive motor 32 is working, control the drive motor 32 to press as shown. Figure 6 In the shown view, rotating counterclockwise 270 degrees, the movable shaft 37 first slides from the straight rail 2 353 to the arc rail 351. The mounting arm 38 first drives the suction cup frame 302 to move a distance away from the film mounting frame 4. Then the movable shaft 37 slides from the arc rail 351 to the straight rail 1 352. The mounting arm 38 then rotates counterclockwise 90 degrees, so that the suction cup frame 302 is in a horizontal state and the mounting arm 38 is in a vertical state. It will also move down a distance. At this time, multiple pneumatic suction cups 303 can contact the glass sheet on the glass sheet conveying line 1. When multiple pneumatic suction cups 303 work at the same time, they will pick up the glass sheet.

[0044] Figure 2 The state shown is the working state after the glass sheet is picked up by multiple pneumatic suction cups 303. Then, by controlling the drive motor 32 to rotate 270 degrees clockwise, the vertical gripping device 3 can return to the starting position through the same working principle described above. Figure 1 As shown, by having the vertical gripping devices 3 on both sides work simultaneously, the two glass sheets can be clamped at the downward-pulling film on the film roller 43 to complete the bonding. Then, the staff can cut the film and stop the multiple pneumatic suction cups 303 from working, so that the bonded glass can be removed.

[0045] It should be noted that, in the above process, because the movable shaft 37 can slide in the straight rail two 353 and the straight rail one 352, when the mounting arm 38 rotates, it will first move a distance in the horizontal direction, then turn 90 degrees, and then move a distance in the vertical direction. During the splicing process, it does not cause interference to the glass sheet during rotation, ensuring smooth splicing.

[0046] Embodiment Two

[0047] This embodiment is based on embodiment one, and further improves the auxiliary conveying frame 5. The purpose is to quickly and damage-free take out the completed spliced laminated glass after splicing, to ensure the overall work efficiency.

[0048] As shown in Figure 7 , the auxiliary conveying frame 5 includes a base plate 51, two slide rails 52 are symmetrically and fixedly installed at the upper end of the base plate 51, two clamping plates 53 are symmetrically provided at the upper end of the two center shafts 42, and the two clamping plates 53 are parallel to each other and the glass sheet conveying line 1, and the two clamping plates 53 are perpendicular to each other and the two slide rails 52, and the clamping plates 53 can slide relative to the slide rails 52. A buffer seat 54 is fixedly installed at the upper end of the base plate 51, and the buffer seat 54 is located between the two clamping plates 53. Two vertical plates 55 are fixedly installed at the upper end of the base plate 51 on both sides. The lower part of the end of the two clamping plates 53 away from each other is fixedly installed with a telescopic spring 56, and the end of the telescopic spring 56 away from the clamping plate 53 is fixedly connected with the vertical plate 55. The telescopic spring 56 provides elastic force, so that the clamping plate 53 can rebound. Specifically, the two telescopic springs 56 are in a compressed state, so that the two clamping plates 53 always have a tendency to approach each other.

[0049] Further, as shown in Figure 8 , the clamping plate 53 includes a fixed frame 531, an arc-shaped extension 533 is fixedly installed at the top of the fixed frame 531, and the arc-shaped extension 533 is integrally formed with the fixed frame 531. The arc-shaped extension 533 is inclined to the side close to the glass sheet conveying line 1, so that the gap between the two clamping plates 53 is trumpet-shaped at the upper part, so as to smoothly fall into the laminated glass after splicing between the two clamping plates 53. An installation cavity is provided in the middle of the fixed frame 531 and the arc-shaped extension 533, a plurality of straight rods 534 are fixedly installed in the installation cavity at equal intervals, a roller one 535 is rotatably installed on the outer surface of each straight rod 534 through a damping bearing, and two slide seats 532 used in cooperation with the slide rails 52 are symmetrically and fixedly installed at the bottom of the fixed frame 531.

[0050] As can be seen, since the plurality of rollers one 535 are connected with the straight rod 534 through the damping bearing, when the two clamping plates 53 clamp the laminated glass after splicing, the plurality of rollers one 535 directly contact the surface of the laminated glass, the surface of the rollers one 535 can be provided with an anti-skid rubber layer, further improving the friction between the rollers one 535 and the laminated glass, and the laminated glass can be slowly lowered for buffering through the friction between the rollers one 535 and the laminated glass and the gravity of the laminated glass, avoiding violent impact and causing damage to the glass.

[0051] In order to further protect the laminated glass and facilitate the laminated glass to be taken off, as shown in Figure 9 and Figure 10 The buffer seat 54 includes a support plate 541 and a bearing seat 543, the support plate 541 is fixedly installed at the upper middle part of the base plate 51, and the both sides of the support plate 541 are provided with notch grooves 542 for the sliding rails 52 to pass through, avoiding interference between the sliding rails 52 and the support plate 541, the bearing seat 543 is provided with a buffer cavity 544 at the lower end for cooperation with the support plate 541, the upper part of the support plate 541 is slidably installed in the buffer cavity 544, and a plurality of buffer springs 545 are fixedly arranged at equal distances between the top end of the support plate 541 and the top wall of the buffer cavity 544, the top end of the bearing seat 543 is provided with a mounting groove, and a plurality of rollers two 546 are fixedly arranged at equal distances in the mounting groove, in the embodiment, the surface of the rollers two 546 can also be covered with a rubber layer, which can have an anti-skid effect; the both ends of the support plate 541 are fixedly installed with limiting side plates 547, the size of the limiting side plates 547 is greater than that of the buffer cavity 544, and the two support plates 541 are tightly attached to the both ends of the bearing seat 543 for limiting, so that the bearing seat 543 always moves in the vertical direction.

[0052] In addition, the convex strip 536 is fixedly installed at the lower part of one end of the arc-shaped extension 533 close to the buffer seat 54, and the one end of the convex strip 536 close to the buffer seat 54 is provided with an inclined surface, the lower part of the bearing seat 543 is also provided with an inclined surface, and the inclined surfaces on the both sides of the bearing seat 543 have the same slope as the inclined surface on the convex strip 536, when the straight rod 534 moves downward, the two inclined surfaces can be matched to make the two clamping plates 53 move apart.

[0053] As can be seen from the above, the specific implementation scenario of the embodiment is:

[0054] After the splicing is completed, the staff cuts the film, and the laminated glass naturally falls into the two clamping plates 53 under its own gravity, and the arc-shaped extension 533 plays a protective role, ensuring that the laminated glass can smoothly enter the gap between the two clamping plates 53. In this process, the roller one 535 directly contacts the laminated glass, and the laminated glass slowly descends by using a damping bearing. When the laminated glass descends to the upper end of the buffer seat 54 and presses the roller two 546, the buffer spring 545 contracts, the bearing seat 543 descends, and the two clamping plates 53 are separated to the two sides through the inclined surface of the bearing seat 543 and the convex strip 536. The extension spring 56 further contracts. At this time, the two clamping plates 53 loosen the clamping of the laminated glass, and the staff can pull out the laminated glass more labor-saving and faster by cooperating with the roller two 546, which significantly improves the work efficiency.

[0055] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
