Description

Technical Field

[0001] The invention relates to an edge folding device for automatically folding an insulation board, in particular to an automatic edge folding device. Background Art

[0002] Vacuum insulation panel is a kind of vacuum insulation material, which can effectively avoid heat transfer caused by air convection and greatly reduce the thermal conductivity. The structure of vacuum insulation panel usually includes core material and barrier film wrapped on the outside of the core material. The core material is plate-shaped and usually composed of one or more materials with low thermal conductivity, such as glass fiber, polyester fiber and other materials with very low thermal conductivity. The barrier film is usually made of prefabricated bag-shaped barrier bag on the core material and a getter is placed in the bag to ensure the stability of the interior after vacuuming. Then the bagged core material is vacuumed. After vacuuming, the vacuum insulation panel is completed.

[0003] After the core material is covered with a barrier bag and vacuumed, the barrier bag will be flattened around the core material due to the effect of external atmospheric pressure, thus forming soft pages around the core material, generally with two opposite soft pages and soft pages connected in a ring around the core material. In order to prevent the soft pages from affecting the transportation and installation of the vacuum insulation board, and to prevent the soft pages from being damaged and affecting the sealing, it is usually necessary to manually fold the soft pages and then glue them tightly to the insulation board, but manual folding is labor-intensive and has low production efficiency.

[0004] Therefore, there is a fully automatic forming equipment for vacuum insulation panels, such as the one disclosed in Chinese patent CN202410725676, which can realize the automatic folding and edge sealing of the long side leaves (soft leaves) and short side leaves (soft leaves) of the insulation board core material. In this scheme, the four corners of the core material are pre-pinched and indented by the corner pinching mechanism, so that the long side leaves are pre-retracted into the range of the short side leaves, and the folds and indentations are used to limit the subsequent movement direction of the long side leaves, so that when the subsequent short side leaves are folded together with the long side leaves and attached to the core material, the long side leaves will not be exposed from under the cover of the short side leaves. However, in this scheme, the long side leaves are retracted into the short side leaves and then folded, and the mutual superposition of multiple soft leaves will cause the corners of the insulation board core material to have protruding sharp corners, and the stress is concentrated at the sharp corners, which are easy to bump and cause deflation or defect, resulting in unqualified products and affecting the use of subsequent products.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] like Figure 1 and Figure 2As shown, an automatic folding device of this embodiment includes an equipment bracket 100, a lifting device 200, a corner picking device 300 and a flattening device 400.

[0021] The jacking device 200 is arranged on the front side of the equipment support 100; the corner device 300 is arranged above the jacking device 200, and the insulation board 600 is placed between the corner device 300 and the jacking device 200. The flattening device 400 is connected to the equipment support 100 and has a flattening movable block 410 that can move between the corner device 300 and the jacking device 200.

[0022] The corner picking device 300 is used to press down and pick the corners of the soft page 610 of the insulation board 600; the lifting device 200 is used to lift up, fold and shape the soft page 610; the flattening device 400 is used to press and fix the lifted and folded soft page 610 to the surface of the insulation board 600; in this way, the automatic folding, pressing and fixing of the soft page 610 is achieved through the coordinated cooperation of multiple devices and multiple actions.

[0023] In order to prevent sharp corners from appearing on the soft page 610 after being pressed, the present embodiment provides a corner lifting device 300 to lift the soft page 610, first forming a small angle 620 and then folding it, thereby avoiding the generation of sharp corners, preventing the barrier film from being damaged, and improving product reliability.

[0024] The angle shaping device 300 includes an angle shaping plate 310, an angle shaping X-axis module 320 and an angle shaping Z-axis module 330; the angle shaping plate 310 moves left and right under the drive of the angle shaping X-axis module 320, and moves up and down under the drive of the angle shaping Z-axis module 330; at least one side of the angle shaping plate 310 has a shaping angle 311.

[0025] In this embodiment, the number of the angle shaping plates 310 of the angle shaping device 300 is two. The two angle shaping plates 310 are arranged at intervals on the left and right, and are driven by the angle X-axis module 320 to move away from or close to each other. The two angle shaping plates 310 have shaping angles 311 on the opposite sides thereof.

[0026] In this embodiment, the shaping angle 311 of the angle shaping plate 310 includes an upper edge 312 and a side edge 313, and the outer end of the upper edge 312 and the upper end of the side edge 313 are connected to form the shaping angle 311; the inner end of the upper edge 312 is offset upward, and the lower end of the side edge 313 is retracted, so the shaping angle 311 formed between the upper edge 312 and the side plate 313 is a convex shape.

[0027] By this, when using the automatic folding equipment, refer to Figures 11 to 15 , taking a rectangular insulation board 600 with four right-angled sides as an example, the following steps can be used to automatically fold the insulation board 600: Step S1, using other automated equipment to fold the two long side soft pages 611 of the insulation board 600 upward and inward and press them on the top of the insulation board 600 (such as Fig.11 ), and then use a feeding device such as a robot or a conveyor belt to transport the insulation board 600 after the long side soft page 611 is folded to between the lifting device 200 and the corner pick device 300 in the automatic folding device, and keep the short side soft page 612 of the insulation board 600 to be folded extended in front of the lifting device 200 and the corner pick device 300 (such as Fig.12 ), since the two long-side soft pages 611 have been pre-folded, the long-side soft pages 611 on the left and right sides of the short-side soft pages 612 will form two "C"-shaped parts 613 with openings facing each other.

[0028] Step S2, the Z-axis module 330 drives the two left and right spaced corner shaping plates 310 to synchronously descend to press down the short edge soft pages 612 and the two "C"-shaped parts 613 extending forward (such as Fig.12 ), so that it can be turned downward 90° and supported by the front side wall of the lifting device 200 below, thereby preventing the soft page 610 from being deformed.

[0029] Step S3, the two angle shaping plates 310 are driven to move left and right apart from each other by the angle shaping X-axis module 320, so that the two angle shaping plates 310 can be respectively inserted into the openings of the "C"-shaped portion 613, and the two angle shaping plates 310 are driven to rise by the angle shaping Z-axis module 330, so that the "C"-shaped portion 613 is shaped and pushed open by the convex shaping angle 311, so that the top of the "C"-shaped portion 613 forms a convex small angle 620 (such as Fig.13 ), and then use the X-axis module 320 and the Z-axis module 330 to drive the corner shaping plate 310 to leave the "C"-shaped portion 613 and the short-side soft page 612 area.

[0030] Step S4, using the lifting device 200 to flip and lift the short-side soft page 612 located at the front side of the lifting device 200, which is pressed down and has a small angle 620 after the angle shaping (such as Fig.14 ), so that the short-side soft page 612 after the corner shaping can be turned upward by 180 degrees and located in front of the insulation board 600.

[0031] Step S5, using the flattening device 400 to press the lifted and folded short-side soft page 612 toward the rear side (such as Fig.15 ), the flattening movable block 410 can be used to push the short-side soft page 612 from the front to the back, so that it can be flipped backwards 90 degrees to fit the top of the insulation board 600, and the flattening movable block 410 can be moved backward and pressed downward at the same time to fix the short-side soft page 612 to the surface of the insulation board 600. The top surface of the insulation board 600 can be pre-coated with glue such as hot melt adhesive to achieve the pressing and fixing of the short-side soft page 612.

[0032] The insulation board 600 produced by automatic folding using the above-mentioned method and steps can form small angles 620 on both sides of the position between the short-side soft page 612 and the end of the insulation board 600 due to the corner shaping performed by the corner picking device 300, so that the overlapping area between the short-side soft page 612 and the two "C"-shaped parts 613 and the end of the insulation board 600 will not form a protruding sharp corner, which can avoid damage and leakage caused by bumps, and can improve the yield and reliability of the insulation boards 600 produced by this equipment to meet customer needs.

[0033] In this embodiment, by setting two angle shaping plates 310, the above method can be used to synchronously angle the "C"-shaped parts 613 on both sides. Of course, only one angle shaping plate 310 can be set, and then shaping angles 311 are set on both sides of the single angle shaping plate 310, and then by reciprocating left and right movement and rising, the purpose of shaping the angles of the "C"-shaped parts 613 on both sides can be achieved. Of course, only one angle shaping plate 310 and one shaping angle 311 can be set, and then the angles of the "C"-shaped parts 613 on both sides can be respectively raised by flipping the angle shaping plate 310. In combination with the above, it can be known that the number of the angle shaping plates 310 and the shaping angles 311 is not limited to two in this embodiment. On the basis of knowing the concept of the present invention and the above examples, those skilled in the art can combine a variety of conventional methods to achieve angle shaping.

[0034] The shaping angle 311 in this embodiment takes the convex shape as an example, and the above-mentioned method can be used to quickly realize shaping and corner picking; of course, the shaping angle 311 can also be a right angle. For example, the upper side 312 of the shaping angle 311 is set horizontally, and the side 313 of the shaping angle 311 is set vertically. In this case, the shaping angle 311 is a right angle. When the right-angle shaping angle 311 is used for corner picking shaping, it is necessary to cooperate with the corner picking X-axis module 320 and the corner picking Z-axis module 330 to control the corner picking shaping plate 310 to move left and right while picking up, so as to facilitate the forming of the small angle 620.

[0035] Alternatively, when the inner end of the upper side 312 of the shaping angle 311 is offset upward and the side 313 is vertically set, the corresponding small angle 620 can be formed by adjusting the movement trajectory of the angle shaping plate 310; similarly, the upper side 312 of the shaping angle 311 can be set horizontally, and the lower end of the side 313 can be retracted.

[0036] Specific as Fig.14 The angle A1 of the inner end of the upper edge 312 that deviates upward may be 20 to 25 degrees, and the angle A2 of the lower end of the side edge 313 that is retracted may be 5 to 15 degrees.

[0037] like Figure 3As shown, the angle-raising device 300 of this embodiment also includes an angle-raising mounting plate 340; the angle-raising X-axis module 320 includes two angle-raising X-axis driving sub-modules 321 installed on the angle-raising mounting plate 340, and the two angle-raising X-axis driving sub-modules 321 are respectively connected to and independently drive the two angle-raising shaping plates 310 to move left and right; since the left and right angle-raising shaping plates 310 are both independently powered, this embodiment can not only automatically fold the rectangular insulation board 600 with right-angled sides, but also automatically fold the insulation board 600 with beveled sides. The angle-raising Z-axis module 330 drives the angle-raising mounting plate 340 to move up and down, so as to drive the two angle-raising shaping plates 310 to move up and down.

[0038] The corner X-axis driving sub-module 321 can adopt a synchronous belt type linear module; the corner X-axis driving sub-module 321 includes a corner X-axis guide rail 322, a corner X-axis slider 323 and a synchronous belt assembly 324; specifically, a corner X-axis guide rail 322 extending left and right along the X-axis direction can be provided on the corner mounting plate 340, and the two corner X-axis driving sub-modules 321 of this embodiment can share one X-axis guide rail 322, and the two corner shaping plates 310 can be respectively installed on two spaced corner X-axis sliders 323 slidingly connected on the corner X-axis guide rail 322; and the two corner X-axis sliders 323 can be respectively connected to the synchronous belts of the two synchronous belt assemblies 324, so as to drive the corner X-axis slider 323 and the corner shaping plate 310 to move left and right along the X-axis direction through the rotation of the synchronous belt of the corner X-axis driving sub-module 321.

[0039] See also Figure 2 and Figure 4 The equipment support 100 may include a lower support 110 , an upper movable support 120 , an upper connecting support 130 and a top support 140 .

[0040] The left and right sides of the lower bracket 110 are respectively provided with two upwardly extending connecting pillars 111 connected to the top bracket 140, and the upper movable bracket 120 and the upper connecting bracket 130 are both located between the two connecting pillars 111; the upper movable bracket 120 can be moved up and down and slidably connected to the upper connecting bracket 130 on the upper part of the equipment bracket 100, and the upper connecting bracket 130 can be moved forward and backward and slidably connected to the top bracket 140 on the top of the equipment bracket 100, so that it can be moved and adjusted when the position of the soft page pick angle changes.

[0041] The lifting device 200 is arranged on the front side of the lower bracket 110, and the corner lifting device 300 is arranged on the front side of the upper movable bracket 120; that is, the corner lifting mounting plate 340 of the corner lifting device 300 can be moved up and down and slidably connected to the front side of the upper movable bracket 120 on the upper side of the equipment bracket 100.

[0042] Specifically, the angle Z-axis module 330 can be a screw-type linear module; the angle Z-axis module 330 includes an angle Z-axis slider 331, an angle Z-axis guide rail 332, an angle Z-axis screw 333 and an angle Z-axis screw motor 334; the left and right ends of the angle mounting plate 340 are respectively connected to the angle Z-axis guide rails 332 set on the left and right sides of the front side of the upper movable bracket 120 by setting the angle Z-axis slider 331, and can slide up and down under the control of the angle Z-axis screw 333 and the angle Z-axis screw motor 334. The angle Z-axis screw motor 334 can be installed on the upper end of the upper movable bracket 120, and drive the angle Z-axis screw 333 to rotate through the synchronous connection belt (not shown) and two synchronous gears 335 to control the up and down movement of the angle mounting plate 340.

[0043] Further, if Figure 2 In this embodiment, the upper end of the angle shaping plate 310 can be connected to the angle X-axis driving sub-module 321 through the angle Y-axis driving mechanism 350, and the angle Y-axis driving mechanism 350 drives the angle shaping plate 310 to reciprocate along the front-rear direction of the Y-axis.

[0044] Specifically, the angle-lifting Y-axis driving mechanism 350 can be an angle-lifting Y-axis driving cylinder 351 and an angle-lifting Y-axis sliding seat 352. The angle-lifting Y-axis sliding seat 352 is fixedly connected to the angle-lifting X-axis slider 323. The angle-lifting Y-axis driving cylinder 351 is connected to the angle-lifting Y-axis sliding seat 352. The power end of the angle-lifting Y-axis driving cylinder 351 is connected to the upper end of the angle-lifting shaping plate 310. The angle-lifting Y-axis driving cylinder 351 can drive the angle-lifting shaping plate 310 to move forward and backward.

[0045] With this structure, at the end of step S3 of the above method, a step of fixing the small corner 620 can be added. When the Z-axis module 330 drives the two corner shaping plates 310 to rise and leave the short-side soft page 612 area, when the height of the corner shaping plates 310 is the same as that of the small corner 620, the X-axis module 320 can also drive the two corner shaping plates 310 to move left and right respectively to be located in front of the two small corners 620, and then the Y-axis driving cylinder 351 is used to drive the two corner shaping plates 310 to press the small corner 620 backwards, so as to press the small corner 620 against the end surface of the insulation board 600 for fixing, and then step S4 is performed to ensure that the small corner 620 is always formed and will not be deformed when the short-side soft page 612 is lifted by the lifting device 200, and when step S5 is to be performed, the corner lifting device 300 is completely separated from the short-side soft page 612.

[0046] like Figures 5 to 7As shown, the lifting device 200 of this embodiment includes a lifting plate 210 and a lifting mounting frame 220. The lifting plate 210 can be lifted up and down and installed on the front side of the lifting plate mounting frame 220, and the lifting plate mounting frame 220 can be moved forward and backward and installed on the front side of the lower bracket 110 of the equipment bracket 100.

[0047] Thus, the lifting plate 210 can be driven to move forward and backward by the lifting plate mounting frame 220, and the lifting plate 210 can be moved up and down to realize the flipping operation of the short-side soft page 612 after the corner shaping in step S3.

[0048] The left and right ends of the lifting plate 210 can be respectively provided with a lifting plate Z-axis module 230, and specifically, the lifting plate Z-axis module 230 can be a screw-type linear module. The lifting plate Z-axis module 230 includes a lifting plate slider 231, a lifting plate guide rail 232, and a lifting plate linear screw assembly 233; the two ends of the lifting plate 210 can be respectively slidably connected to the lifting plate guide rails 232 at the left and right ends of the lifting plate mounting frame 220 through the lifting plate slider 231, and driven by the lifting plate linear screw assembly 233 provided on the lifting plate mounting frame 220 to rise and fall.

[0049] The lifting plate mounting frame 220 can realize forward and backward movement relative to the equipment support 100 through the lifting plate mounting frame Y-axis module 240; the lifting plate mounting frame Y-axis module 240 includes a lifting plate mounting frame guide rail 241, a lifting plate mounting frame slider 242 and a lifting plate mounting frame linear screw assembly 243; the lifting plate mounting frame 220 can be provided with a lifting plate mounting frame guide rail 241 at the bottom of the left and right ends respectively, and the equipment support 100 can be provided with a lifting plate mounting frame slider 242 at the left and right ends to slide with the corresponding lifting plate mounting frame guide rail 241, and at the same time, the lifting plate mounting frame 220 can be driven by the lifting plate mounting frame linear screw assembly 243 installed in the middle of the lower support 110 of the equipment support 100 to move forward and backward.

[0050] like Figure 8 As shown, the automatic folding device further includes an auxiliary shaping mechanism 500; the auxiliary shaping mechanism 500 is arranged in front of the lifting device 200, and is used to shape the soft leaf 610 located in front of the lifting device 200 pressed down by the angle-lifting device 300. In combination with step S3 of the above method, the short-side soft leaf 612 can be pressed against during the angle-lifting shaping process to produce a corresponding indentation, so as to keep the shaped short-side soft leaf 612 from being easily deformed during the subsequent flipping process.

[0051] See also Fig. 9The auxiliary shaping mechanism 500 includes a shaping slide 510, two shaping pressure plates 520 and two shaping pressure plate seats 530; the two shaping pressure plate seats 530 are slidably connected to the front side of the shaping slide 510 at left and right intervals, and can slide left and right along the shaping slide 510; the shaping pressure plate 520 is arranged on the shaping pressure plate seat 530, and can drive the shaping pressure plate 520 to move forward and backward.

[0052] Thus, in step S3, when the two corner shaping plates 310 are respectively inserted into the openings of the "C"-shaped portion 613 and lifted upward, the shaping pressure plate seat 530 can drive the shaping pressure plate 520 to press against the lifted "C"-shaped portion 613 and the corner shaping plate 310 inside the "C"-shaped portion 613, and then make the two shaping pressure plate seats 530 and the shaping pressure plate 520 move relatively close to each other along the shaping slide 510 to press and fix the shape of the "C"-shaped portion 613 after shaping and lifting, and press out an indentation.

[0053] Specifically, the front side of the shaping slide 510 is provided with a rack 511 extending left and right and a shaping slide guide rail 512; the shaping plate seat 530 is provided with a shaping plate seat slider 531 slidably connected to the shaping slide guide rail 512, and the shaping plate seat 530 can also be installed with a shaping slide motor 532, the power end of the shaping slide motor 532 is connected to a gear 533 installed on the rear side of the shaping plate seat 530, and the gear 533 is meshed with the rack 511, and the shaping slide is driven by the shaping slide.

[0054] Furthermore, the auxiliary shaping mechanism 500 also includes two small-angle shaping components 540; the small-angle shaping components 540 are respectively installed and connected to the two shaping pressure plates 520; the small-angle shaping components 540 include a small-angle shaping bracket 541, a small-angle shaping cylinder 542 and a small-angle shaping block 543; the small-angle shaping bracket 541 is installed on the front side of the shaping pressure plate 520 so as to be able to slide up and down, the small-angle shaping cylinder 542 is installed on the top of the small-angle shaping bracket 541, and the small-angle shaping block 543 is installed at the rear end power output end of the small-angle shaping cylinder 542, which is used to drive the small-angle shaping block 543 to move back and forth on the top of the shaping pressure plate 520.

[0055] Thus, in step S3, after the two corner shaping plates 310 leave the "C"-shaped portion 613 and the short-side soft page 612 area, the aforementioned shaping plate 520 is pressed close to the "C"-shaped portion 613, and the small-angle shaping block 543 located on the top of the shaping plate 520 can be driven by the small-angle shaping cylinder 542 to press against the root of the small angle 620 to press out corresponding indentations to facilitate subsequent folding and forming.

[0056] Specifically, the small angle shaping bracket 541 can be slidably connected to the shaping platen guide rail 545 arranged on the rear side of the shaping platen 520 through a number of small angle shaping sliders 544, and can be driven by the vertically arranged small angle shaping lifting cylinder 546 to move up and down. The main body and the power end of the small angle shaping lifting cylinder 546 are respectively connected to the small angle shaping bracket 541 and the shaping platen 520.

[0059] Thus, by utilizing the movable flattening block 410 that can move forward and backward, the flipped up, angle-shaped short-side soft leaf 612 can be pressed against the top surface of the insulation board 600 for fixation.

[0060] In addition, the present embodiment is provided with a flattening retaining wall 440, and a slit 450 is formed between the flattening retaining wall 440 and the lifting device 200. When the flattening movable block 410 pushes the flipped up short side soft leaf 612 from front to back, the short side soft leaf 612 needs to pass through the slit 450 to be attached to the top of the insulation board 600 (such as Fig.15As shown), when the flattening movable block 410 pushes the short side soft pages 612 from front to back, the short side soft pages 612 below the flattening movable block 410 will be pressed against the surface of the insulation board 600, while the short side soft pages 612 above the flattening movable block 410 will be blocked by the bottom of the flattening retaining wall 440, thereby increasing the friction, that is, they will be subjected to a certain pulling force, so that the short side soft pages 612 below the flattening movable block 410 are always taut, so that they can fit more smoothly to the surface of the insulation board 600 when pressed, so that the core material of the product is wrapped more tightly, the surface is smoother, and the quality and appearance of the insulation board 600 produced are better.

[0061] In this embodiment, the movable block lifting mechanism 430 may be a screw-type linear module.

[0062] The movable block forward and backward moving mechanism 420 can also be a screw-type linear module. Specifically, the movable block forward and backward moving mechanism 420 can include two movable block front and rear slide plates 421 arranged on the left and right and a movable mechanism connecting horizontal plate 422 connected to the rear ends of the two movable block front and rear slide plates 421.

The overall equipment is small in size and space saving is achieved through reasonable layout.

[0065] The present invention is provided with a corner lifting device 300 with a corner lifting shaping plate 310, which can pull out a small corner 620 in advance before the short side soft page 612 is folded, avoiding the sharp corner that may be generated after direct folding, and improving the product yield. The short side soft page 612 and the long side soft page 611 of this embodiment are relative, and are not limited to this in specific implementation.

[0066] The present invention also provides an auxiliary shaping mechanism 500 to assist in pressing the small corner 620 lifted by the corner picking device 300, pressing out a corresponding indentation, and facilitating the flipping of the shaped short-side soft page 612 by the lifting device 200.
