[0002] VIP vacuum insulation board is a new type of insulation board that is widely used in building insulation and industrial insulation, especially in the fields of refrigerators and freezers. Due to its excellent heat insulation effect, it has a huge market.

[0003] During the production of VIP vacuum insulation panels, packaging equipment is needed to wrap the outer side of the panels in bags and fold the excess edge strips. Existing folding processes are mainly divided into manual processing and folding equipment processing. In the manual folding process, manual folding is inefficient and inconsistent, making it unsuitable for mass production. As for folding equipment, the current industry technology uses straight-line folding, but in actual production, due to its complex structure, it has a high failure rate and serious air leakage and defective products, so it still cannot replace manual processing.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 Please see Figures 1-15 The diagram shows a fully automatic folding and corner-folding device for VIP heat insulation panels, including a housing 101 for folding the corners of the outer packaging bag of the VIP heat insulation panels during the packaging process. The housing 101 is provided with an inlet 102 for feeding the VIP heat insulation panels and an outlet 103 for discharging the VIP heat insulation panels. An operating table 104 is fixed inside the housing 101. The device also includes: Automatic centering mechanism 2 is set on the operating table 104 for centering and positioning the VIP heat insulation plate after feeding; The folding mechanism 3 is set on the operating table 104 and is used to fold the packaging bag on the side of the VIP heat insulation board. The corner-folding mechanism 4 is set on the operating table 104 and is used to fold the packaging bag on the side of the VIP heat insulation board inward at an angle. In addition, a first robotic arm 5 and a second robotic arm 6 are installed on the operating table 104. The first robotic arm 5 is set between the automatic centering mechanism 2 and the folding mechanism 3 to assist in the handling of the VIP heat insulation board. The second robotic arm 6 is set between the folding mechanism 3 and the corner folding mechanism 4 to assist in the handling of the VIP heat insulation board. An adhesive application component is provided between the automatic centering mechanism 2 and the folding mechanism 3 and between the folding mechanism 3 and the corner folding mechanism 4 for adhesive application during the corner handling process. It should be noted that during the packaging process of VIP heat insulation panels, corner-folding equipment is used to fold the edges of the VIP heat insulation panels. In this process, robotic transfer is used, with fully automatic centering, fully automatic glue spraying, and fully automatic edge folding and corner folding. Clamping and positioning are used for precise and non-destructive edge folding, and a fitting push-pull mechanism is used for non-destructive edge pressing. For corner folding, an internal inclined pre-folding is used to prevent leakage caused by bulging corners when folding at the rear end. When folding at the rear end, a lifting clamping mechanism and a fitting push-pull mechanism are still used. Silicone is used as contact points at all joints with the surface, ensuring non-destructive operation while improving the tightness and flatness of the surface after folding. It is worth noting here that the motors and cylinders used in this application are conventional drive components, and their working principles and operation methods are well-known technologies, so they will not be described in detail here.

[0020] Preferably, the automatic centering mechanism 2 includes a first conveyor 701 for conveying the VIP heat insulation board, which is disposed on the operating table 104. A lifting platform 702 is disposed below the operating table 104. Multiple sets of first cylinders 703 for lifting and driving the lifting platform 702 are disposed inside the housing 101. Four sets of slide seats 704 are slidably connected above the lifting platform 702 and arranged symmetrically in pairs. Centering plates 705 for positioning against the side of the VIP heat insulation board are fixed on the slide seats 704. A drive assembly for driving the two sets of slide seats 704 arranged opposite each other is disposed on the lifting platform 702. It should be noted that: the lifting platform 702 and the four sets of centering plates 705 above the lifting platform 702 are driven to rise by the first cylinder 703. After the rise is completed, the driving component drives the two opposing sets of centering plates 705 to move closer to each other. During the movement, the four sets of centering plates 705 abut against the four sides of the VIP heat insulation plate. Through the abutment action, the VIP heat insulation plate is centered and positioned, which facilitates more accurate handling in the future. After the VIP heat insulation plate is centered, positioned and handled, the centering plates 705 are driven to fall and reset, so as to avoid interference with the subsequent conveying of the VIP heat insulation plate on the first conveyor 701.

[0021] Preferably, the drive assembly includes a gear 801 rotatably connected to the lifting platform 702, two sets of racks 802 slidably connected to the lifting platform 702 in an interleaved manner, one end of each set of racks 802 being fixed to two sets of slides 704, the gear 801 being located between the two sets of racks 802 and meshing with each other, and a motor 803 for driving the gear 801 being installed at the bottom of the lifting platform 702; It should be noted that: by installing motor 803, the gear 801 is driven to rotate. During the rotation of gear 801, the gear 801 and the two sets of racks 802 mesh with each other, driving the two sets of slides 704 to move closer or further apart. The movement of slides 704 drives the two sets of centering plates 705 to move synchronously.

[0022] Preferably, the folding mechanism 3 includes: The pushing edge assembly consists of two symmetrically arranged sets. These two sets of pushing edge assemblies are used to push the packaging bags on both sides of the VIP heat insulation board toward the upper center of the VIP heat insulation board. The flange assembly is provided in two sets. The two sets of flange assemblies are used to flatly support the packaging bags on both sides of the VIP heat insulation board towards the outside of the VIP heat insulation board. The pre-folding corner assembly is used to fold the corners of the packaging tape at the edges of the VIP insulation board after the edge is turned up. There are four sets of corner folding assemblies, and the four sets of corner folding assemblies are evenly distributed around the VIP insulation board after it is placed. The pushing assembly includes a first push plate 901 disposed above the operating table 104. Multiple sets of first push blocks 902 are fixedly arranged horizontally above the first push plate 901. A first mounting bracket 903 is fixed inside the chassis 101. A first movable plate 904 is disposed above the first mounting bracket 903. A second cylinder 905 for lifting and lowering the first movable plate 904 is mounted on the first mounting bracket 903. A third cylinder 906 for horizontally driving the first push plate 901 is mounted on the first movable plate 904. A first mounting frame 907 is provided above the first push plate 901. Multiple sets of first pressure blocks 908 are fixed in a horizontal arrangement on the first mounting frame 907. Each set of first pressure blocks 908 is staggered with each set of first push blocks 902. A second moving plate 909 is provided above the first mounting frame 903. A fourth cylinder 910 for raising and lowering the second moving plate 909 is provided on the first mounting frame 903. A fifth cylinder 911 for moving the first mounting frame 907 horizontally is installed on the second moving plate 909.

[0023] Preferably, the flanging assembly includes a flipping plate 1001 disposed above the operating table 104, two sets of symmetrically arranged L-shaped flanging rods 1002 mounted on the flipping plate 1001, a second mounting bracket 1003 fixed on the operating table 104, and a flipping motor 1004 for flipping the flipping plate 1001 mounted on the second mounting bracket 1003; the pre-angle bending assembly includes a third mounting bracket 1101 fixed on the operating table 104, a third moving plate 1102 disposed on the third mounting bracket 1101, a sixth cylinder 1103 for laterally moving the third moving plate 1102 mounted on the third mounting bracket 1101, an angle bending plate 1104 for assisting angle bending disposed on one side of the third moving plate 1102, and a seventh cylinder 1105 for lifting and lowering the angle bending plate 1104 mounted on the third moving plate 1102; It should be noted here that: the flipping motor 1004 flips the flipping plate 1001 from a vertical position to face the VIP heat insulation plate. During the flipping process, the L-shaped flange rod 1002 on the flipping plate 1001 flattens the edge strips on both sides of the VIP heat insulation plate outwards. After flattening, the sixth cylinder 1103 pushes the third moving plate 1102 towards the VIP heat insulation plate. During the pushing process, the corner plate 1104 abuts against the edge strips, and with the flat pressing action of the L-shaped flange rod 1002, the edge strips at the four corners of the VIP heat insulation plate are folded and shaped inwards into a slanted angle shape. Then, the seventh cylinder 1105 folds the corners. The downward pressure of plate 1104 causes the pre-folded edge strip to adhere to the adhesive, preparing for the next folding step. After the pre-folding process, the first mounting frame 907 and the first pressure blocks 908 on the first mounting frame 907 are pushed towards the inside of the VIP insulation board by the fifth cylinder 911. During the pushing process, the second moving plate 909 is driven to descend by the fourth cylinder 910, causing the first pressure blocks 908 to move and press down at the same time. Through the movement of the first pressure blocks 908, the edge strips on the sides of the VIP insulation board are turned towards the inside of the VIP insulation board and tightly adhered to the VIP body, completing the edge folding process of the edge strips on both sides of the VIP insulation board.

[0024] Preferably, the bending mechanism 4 includes: A support and fixing component is provided on the operating table 104 for supporting and fixing the VIP heat insulation board after transportation; A conveying assembly, mounted on the operating table 104, is used to convey the processed VIP insulation board toward the discharge port 103. The corner folding assembly consists of two sets, which are set on the operating table 104 for folding the corners of the packaging bags on the VIP heat insulation board. The angle-folding assembly includes a second push plate 1301 disposed above the operating table 104. Multiple sets of second push blocks 1302 are fixed horizontally at the upper end of the second push plate 1301. A fourth mounting bracket 1303 is fixed inside the chassis 101. A fourth movable plate 1304 is disposed on one side of the fourth mounting bracket 1303. An eighth cylinder 1305 is mounted on the fourth movable plate 1304 to assist in the horizontal movement of the second push plate 1301. An air cylinder 1305 is mounted on the fourth mounting bracket 1303 to lift the fourth movable plate 1304. The tenth cylinder 1306 is lowered. A second mounting frame 1307 is provided above the second push plate 1301. Multiple sets of second pressure blocks 1308 are fixed in a horizontal arrangement on the second mounting frame 1307. A fifth moving plate 1309 is provided above the fourth mounting frame 1303. An eleventh cylinder 1310 for assisting the lifting and lowering of the fifth moving plate 1309 is installed on the fourth mounting frame 1303. A twelfth cylinder 1311 for assisting the horizontal movement of the second mounting frame 1307 is installed on the fifth moving plate 1309. It should be noted that: through the cooperation of the tenth cylinder 1306 and the eighth cylinder 1305, the second push plate 1301 and the second push blocks 1302 on the second push plate 1301 are driven to lift and move towards the side of the VIP heat insulation board. Through the movement of the second push blocks 1302, the pre-supported flange is flipped up. After the flange is flipped up, through the cooperation of the eleventh cylinder 1310 and the twelfth cylinder 1311, the second mounting frame 1307 and the second pressing blocks 1308 on the second mounting frame 1307 are driven to push the flipped flange towards the VIP heat insulation board. Under the downward pressing action of the second pressing blocks 1308, the flange is pressed tightly against the adhesive and adheres. Since the VIP heat insulation board was pre-folded inward at an angle in the previous folding process, the effect at this folding station is ensured to be tight and without protruding corners.

[0025] Preferably, the support and fixing assembly includes a support platform 1201 fixed on the operating table 104 for supporting and placing the VIP heat insulation panel, and multiple sets of rotary clamping cylinders 1202 installed on the operating table 104 for fixing the VIP heat insulation panel after placement. It should be noted here that during the process of folding the VIP heat insulation board, the second robotic arm 6 places the folded VIP heat insulation board onto the support platform 1201. After placement, the VIP heat insulation board is pressed and fixed by each set of rotating pressing cylinders 1202. It is worth noting here that the rotary clamping cylinder 1202 is used as a conventional operating component in this application, and its working principle and operation method are well-known technologies, so they will not be described in detail here.

[0026] Preferably, the conveying assembly is disposed between the two sets of angled assemblies. The conveying assembly includes a second conveyor 1401, and multiple sets of lifting cylinders 1402 for assisting the lifting of the second conveyor 1401 are installed inside the housing 101. It should be noted here that after the corner of the VIP heat insulation board is bent, the support and fixation of the VIP heat insulation board are loosened. The second conveyor 1401 is driven to move upward by the lifting cylinder 1402 and come into contact with the VIP heat insulation board. At this time, the VIP heat insulation board is transported outward by the conveying action of the second conveyor 1401. It is worth noting here that the second conveyor 1401 is used as a conventional operating component in this application, and its working principle and operation method are well-known technologies, so they will not be described in detail here.

[0027] Preferably, the glue application assembly includes two sets of symmetrically arranged connecting frames 1501 fixed on the operating table 104, and a glue spray gun 1502 for assisting glue application is installed on the connecting frame 1501. It should be noted that: driven by the first robotic arm 5, the VIP heat insulation board is moved from the automatic centering mechanism 2 to the folding mechanism 3. During the moving process, adhesive is applied to both sides of the upper surface of the VIP heat insulation board through the glue application component between the automatic centering mechanism 2 and the folding mechanism 3. The second robotic arm 6 moves the VIP heat insulation board from the folding mechanism 3 to the corner folding mechanism 4 and fixes it through the support and fixing component. During the moving process, adhesive is applied to the other two sides of the upper surface of the VIP heat insulation board through the glue application component between the folding mechanism 3 and the corner folding mechanism 4. During the glue application process, the glue spray gun 1502 assists in the glue application operation. It is worth noting here that the first robotic arm 5, the second robotic arm 6, and the glue spray gun 1502 are conventional operating components in this application, and their working principles and operating methods are well-known technologies, so they will not be described in detail here.

[0028] In this solution: a fully automatic edge-folding and corner-folding device for VIP insulation panels includes the following steps: During the packaging process of VIP heat insulation panels, a folding device is used to fold the edges of the VIP heat insulation panels. During this process, the VIP heat insulation panels are fed into the first conveyor 701 inside the machine housing 101 through the inlet 102. The first conveyor 701 feeds and transports the VIP heat insulation panels to a designated position. After being positioned, the automatic centering mechanism 2 positions the fed VIP heat insulation panels. Following positioning, the first robotic arm 5 moves the VIP heat insulation panels from the automatic centering mechanism 2 to the folding mechanism 3. During this movement, adhesive is applied to both sides of the upper surface of the VIP heat insulation panels using the adhesive application component between the automatic centering mechanism 2 and the folding mechanism 3, facilitating subsequent folding and packaging. After the VIP heat insulation board is transported and placed, the edges of the VIP heat insulation board are folded by the folding mechanism 3. After the folding is completed, the second robot arm 6 transports the VIP heat insulation board from the folding mechanism 3 to the corner folding mechanism 4 and fixes it by the support and fixing components. During the transport process, the adhesive is applied to the other two sides of the upper part of the VIP heat insulation board by the glue application component between the folding mechanism 3 and the corner folding mechanism 4 to facilitate the adhesion and fixation of the packaging bag after the corner is folded. After the VIP heat insulation board is transported and placed, the edges of the VIP heat insulation board are folded by the corner folding mechanism 4. After the corner is folded, the VIP heat insulation board is transported to the outside of the machine box 101 through the discharge port 103 by the conveying component, thus completing the packaging corner folding of the VIP heat insulation board. During the automatic centering process of the VIP insulation panel, the first conveyor 701 transports the VIP insulation panel between four sets of centering plates 705. After the transport is completed, the first cylinder 703 drives the lifting platform 702 and the four sets of centering plates 705 above the lifting platform 702 to rise. After the rise is completed, the drive assembly drives the opposing sets of centering plates 705 to move closer to each other. During the movement, the four sets of centering plates 705 abut against the four sides of the VIP insulation panel. Through the abutment action, the VIP insulation panel is centered and positioned, which facilitates more accurate handling in the future. After the VIP insulation panel is centered, positioned and transported, each set of centering plates 705 is driven to descend and reset, so as to avoid interference with the subsequent transport of the VIP insulation panel on the first conveyor 701. During the edge-folding process of the VIP heat insulation panel, the first robotic arm 5 places the VIP heat insulation panel on the operating table 104. During placement, the VIP heat insulation panel is centered between the various push-edge components, flanging components, and pre-folding components. After placement, the second cylinder 905 drives the first moving plate 904 and the first push plate 901 to move upwards. During the upward movement of the first push plate 901, the first push blocks 902 lift the edge strips on both sides of the VIP heat insulation panel, causing it to fold upwards. After the first push plate 901 rises and moves, the third cylinder 90... Driven by cylinder 6, the first push plate 901 of each group abuts against the side of the VIP heat insulation plate. Through this abutment, the placed VIP heat insulation plate is clamped and fixed. At this time, the first robot arm 5 releases the VIP heat insulation plate and returns to the centering position. After clamping and fixing, the flipping motor 1004 flips the flipping plate 1001 from a vertical position by 90 degrees to face the VIP heat insulation plate. During the flipping process, the L-shaped flange rod 1002 on the flipping plate 1001 pulls the other two sides of the VIP heat insulation plate to the outside of the VIP heat insulation plate for horizontal support. After horizontal support is completed, the sixth cylinder... 1103 The third moving plate 1102 is pushed towards the VIP insulation board. During the pushing process, the corner plate 1104 abuts against the edge strip, and with the flat pressure of the L-shaped flange rod 1002, the edge strips at the four corners of the VIP insulation board are shaped into an inward angled shape. Then, the seventh cylinder 1105 pushes down the corner plate 1104 to make the pre-folded edge strip adhere to the adhesive, preparing for the next step of folding (this process is very critical, the core is to form an inward angled shape; if it is not shaped with an angle, the next fold will inevitably result in a convex angle). (Folding failure), after pre-folding treatment, the first mounting frame 907 and each set of first pressing blocks 908 on the first mounting frame 907 are pushed towards the inside of the VIP heat insulation board by the fifth cylinder 911. During the pushing process, the second moving plate 909 is driven to descend by the fourth cylinder 910, so that each set of first pressing blocks 908 moves while pressing down. Through the movement of each set of first pressing blocks 908, the edge strips on the side of the VIP heat insulation board are turned towards the inside of the VIP heat insulation board and tightly stuck to the VIP body, thus completing the edge folding treatment of the two side strips of the VIP heat insulation board. During the corner-folding process of the VIP heat insulation panel, the second robotic arm 6 places the folded VIP heat insulation panel onto the support platform 1201. After placement, the VIP heat insulation panel is pressed and fixed by each set of rotary pressing cylinders 1202. After fixing, the cooperation of the tenth cylinder 1306 and the eighth cylinder 1305 drives the second push plate 1301 and each set of second push blocks 1302 on the second push plate 1301 to lift and move towards the side of the VIP heat insulation panel. The pre-supported flange is flipped upwards. After flipping, the eleventh cylinder 1310 and the twelfth cylinder 1311 work together to drive the second mounting frame 1307 and the second pressure blocks 1308 on the second mounting frame 1307 to push the flipped flange toward the VIP heat insulation board. Under the downward pressing action of the second pressure blocks 1308, the flange adheres tightly to the adhesive and forms an adhesion. Since the VIP heat insulation board was pre-folded inwards at an angle during the previous folding process, the effect at this folding station is ensured to be tight and without protruding corners.
