Description

Technical Field

[0001] The invention belongs to the technical field of vacuum insulation panels, and in particular relates to an automatic corner and edge folding device and method for vacuum insulation panels. Background Art

[0002] Vacuum insulation board is a kind of insulation material with excellent insulation effect. Compared with other insulation materials, vacuum insulation board has lower thermal conductivity and better insulation effect under the same thickness conditions. Therefore, it is widely used in industrial insulation and building insulation industry. Folding corners and folding edges is a key step in the production process of vacuum insulation board. For the outer protective bag of vacuum insulation board, aluminum foil bag is often used, which is similar to the packaging bag of compressed biscuits. The four sides of the aluminum foil bag are sealed and the seal has a certain width. The bag as a whole should be larger than the size of the core material. The specific process of folding corners and folding edges is to first fold the short sides of the aluminum foil bag on both sides so that the short sides fit the core material. During the folding process, the four corners will protrude. Fold the other two long sides of the aluminum foil bag to tidy up the protruding corners, and then fold the long sides to fit the core material, so that the aluminum foil bag is the same size as the core material. The existing corner and edge folding of vacuum insulation panels is mostly done manually, which is complicated, time-consuming and labor-intensive, and has extremely low production efficiency. It is difficult to ensure the quality of the products after manual corner and edge folding. Problems such as uneven edges and protruding corners of vacuum insulation panels often occur. In severe cases, the vacuum insulation panels leak and the products become scrapped.

[0003] How to realize automatic corner and edge folding of vacuum insulation panels, reduce labor costs and improve production efficiency is an urgent problem to be solved. Summary of the invention

[0015] The gluing device is used to apply glue to the four edges of the vacuum insulation panel. The glue is a hot-melt colloid, which is ultimately used for bonding and fixing after folding the corners and edges.

[0024] Among them, the corner finishing mechanism adopts a small cylinder, and the head of the cylinder rod is designed with a corner finishing structure to achieve the finishing of the four corners of the vacuum insulation panel, ensure the flatness of the four sides after the folded corners and avoid protruding corners.

[0025] Wherein, the fixing mechanism is installed on both sides of the lifting output device to fix the vacuum insulation panel from both sides after the short side folding is completed.

[0026] There are four corner folding robots, which are installed at the four corners of the long side folding area, corresponding to the four corners of the vacuum insulation panel. There are four corner folding auxiliary mechanisms, which are installed at the inner side of the four corner folding robots, corresponding to the four corner roots of the vacuum insulation panel.

[0028] Wherein, the vertical folding mechanism is installed on the head of the lifting cylinder, and the cylinder controls the vertical folding mechanism to move up and down by telescoping.

[0029] Wherein, the transverse folding mechanism is installed on the head of the transverse folding cylinder, and the cylinder controls the transverse reciprocating movement of the transverse folding mechanism by telescoping.

[0030] The tail of the vertical folding mechanism and the horizontal folding mechanism are quadrilateral, the head is a triangle with an inclination, and the edge has an arc to prevent damage to the vacuum insulation panel. The head of the vertical folding mechanism and the head of the horizontal folding mechanism are used in a cross-coordinated manner to fold the long side.

[0031] There are four corner finishing mechanisms, which are installed on both sides of the transverse folding mechanism, corresponding to the roots of the four corners of the vacuum insulation panel.

[0032] Among them, the lower ends of the linear guide rail and the lifting cylinder are installed on the base, the upper ends of the linear guide rail and the lifting cylinder are connected to the lifting platform, the transmission belt and the transmission motor are installed on the lifting platform, the transmission motor controls the operation of the transmission belt, and the lifting cylinder controls the axial movement of the lifting platform along the linear guide rail through telescopic control, thereby controlling the rise and fall of the transmission belt, thereby realizing the function of the lifting output device to output the vacuum insulation panel to the next process.

[0033] According to another aspect of the present invention, the present invention further provides a method for automatically folding corners and edges of vacuum insulation panels, and the method for automatically folding corners and edges of vacuum insulation panels is implemented by the automatic folding corner and edge folding device for vacuum insulation panels as described above.

[0037] 2. The present invention provides a method of folding the short side first and then the long side. The two orders cannot be reversed. Since the short side of the vacuum insulation panel is very short, it is impossible to fold the corner, and the corner can only be folded on the long side. Moreover, folding the corner after folding the short side can eliminate the problem of protruding corners after folding the short side;

[0038] 3. The present invention can realize accurate positioning of vacuum insulation panels, automatic detection and removal of leaking panels, automatic gluing, and automatic corner and edge folding. It has a high degree of automation and solves the problem that most of the current corner and edge folding of vacuum insulation panels are done manually, greatly reduces manual labor intensity, improves production efficiency, effectively avoids the problem of protruding corners, and ensures product quality.

[0053] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0054] The embodiment of the present invention provides an automatic corner folding and edge folding device and method for vacuum insulation panels, which are applied to the production of vacuum insulation panels. The automatic corner folding and edge folding device can realize fully automated corner folding and edge folding functions, replace manual operations, reduce labor intensity, reduce labor costs, greatly improve production efficiency and ensure product quality after corner folding and edge folding, and solve the problems of uneven edge folding of vacuum insulation panels, protruding corners and even air leakage of vacuum insulation panels that often occur when manual operations are performed.

[0055] The following will refer to Figure 1 to Figure 4 The present invention is described in detail with reference to embodiments.

[0056] Embodiment 1: A vacuum insulation panel automatic corner and edge folding device

[0057] like Figure 1 The figure shows a schematic diagram of an automatic corner folding and hemming device for a vacuum insulation panel of the present invention, which includes a workbench 7 and a positioning device 1, a glue application device 2, a material transporting robot device 3, a short side folding device 4, a long side corner folding and hemming device 5, and a lifting output device 6 arranged on the workbench 7. The glue application device 2, the positioning device 1, and the short side folding device 4 are located on one side of the material transporting robot device 3, and the long side corner folding and hemming device 5 and the lifting output device 6 are located on the other side of the material transporting robot device 3.

[0058] Furthermore, if Figure 1 and Figure 2 As shown, the positioning device 1 includes a conveyor belt mechanism 11 and a positioning link mechanism 12. The positioning link mechanism 12 includes a base 121, a linear guide rail 122, a lifting cylinder 123, a positioning baffle 124, a positioning rotating column 125, a connecting rod cylinder 126, a connecting rod 127 and a connecting rod mechanism fixing plate 128. The base 121 is fixed on the ground, the positioning baffles 124 are four pieces, which are arranged on the four sides of the connecting rod mechanism fixing plate 128, the connecting rod cylinder 126 is two pieces, which are fixed on the connecting rod mechanism fixing plate 128 and are respectively connected to a group of positioning baffles 124 on the opposite side, a central axis is set on the connecting rod mechanism fixing plate 128, the connecting rod 127 is a structure including four single arms, one end of the four single arms is respectively fixedly connected to the central block 129, and the central block 129 is rotatably connected to the central axis on the connecting rod mechanism fixing plate 128 through a bearing structure; the other ends of the four single arms of the connecting rod 127 are respectively hinged to the four positioning baffles 124; as an improved structure, each single arm includes two connecting arms, and the two connecting arms are connected by bolts. After adjusting according to the position of the positioning baffle 124, the bolts between the connecting arms are tightened, or fixed in other ways, so as to fix the shape of the single arm.

[0059] The connecting rod mechanism fixing plate 128 is located below the workbench 7, the cylinder of the lifting cylinder 123 is fixed on the base 121, and the telescopic rod is connected to the lower surface of the connecting rod mechanism fixing plate 128. The lifting cylinder 123 is extended and retracted to drive the connecting rod mechanism fixing plate 128 and the components located on the connecting rod mechanism fixing plate 128 to rise and fall; a notch is set on the workbench 7 at the positioning baffle 124 for the positioning baffle 124 to rise and fall. After the vacuum hot plate insulation board is transported to the conveyor belt mechanism 11, the linear guide 122 and the lifting cylinder 123 control the connecting rod mechanism fixing plate 128 and the connecting rod cylinder 126, the connecting rod 127, and the positioning baffle 124 located thereon to move upward to realize the positioning of the vacuum insulation board.

[0060] The conveyor belt mechanism 11 is divided into two groups and is arranged between a group of positioning baffles 124 located on opposite sides.

[0061] The positioning rotating column 125 is installed on the top of the positioning baffle 124. Before positioning, the position of the vacuum insulation panel between the positioning rotating columns 125 on the surrounding positioning baffles 124 is relatively random, so the next step of positioning is required. During positioning, the connecting rod cylinder 126 controls the positioning baffle 124 to shrink toward the center to position the vacuum insulation panel. During the positioning process, the positioning rotating column 125 will squeeze and push the vacuum insulation panel, and there will be movement between the two, so friction will be generated. The positioning rotating column 125 is designed to be rotatable, and the sliding friction is changed to rolling friction during positioning, which greatly reduces the friction. As a feasible solution, the positioning rotating column 125 adopts a shaft sleeve structure.

[0062] In this embodiment, the two pairs of positioning baffles 124 are respectively connected to the connecting rod 127, and the connecting rod cylinder 126 is fixedly connected to one of the pairs of positioning baffles 124. The connecting rod cylinder 126 controls one pair of positioning baffles 124 to move toward or away from the center through telescopic control, and further controls the movement of the other pair of positioning baffles 124 to achieve the positioning of the vacuum insulation panel.

[0063] The glue applying device 2 includes two sets of glue applying mechanisms, wherein the short side glue applying mechanism 21 applies glue to the short side of the vacuum insulation panel, and the long side glue applying mechanism 22 applies glue to the long side of the vacuum insulation panel, and is finally used for bonding and fixing after folding the corners and edges. The glue applying device 2 adopts a more conventional hot melt glue applying device on the market. Figure 1 As shown, the glue applying device 2 is used to apply glue to the four edges of the vacuum insulation panel, and the glue is a hot-melt colloid.

[0064] The material transport robot device 3 includes a manipulator 31 and a suction cup mechanism 32 .

[0065] The material transport robot device 3 can detect and remove leaks on the vacuum insulation panel of the positioning device 1, and transport the positioned and qualified vacuum insulation panel to the short side folding device 4 for short side folding, and then transport the vacuum insulation panel that has completed short side folding to the long side corner folding device 5 for long side corner folding.

[0066] like Figure 1 and Figure 3 As shown, the suction cup mechanism 32 is designed with leakage detection devices at different positions, and determines whether the vacuum insulation panel is leaking by detecting the thickness at different positions. If a difference in thickness is detected, the leakage is determined as an unqualified product and is removed. Specifically, the suction cup mechanism 32 includes a frame 321, a suction cup 322 arranged on the frame 321, and a leakage detection device 323. The leakage detection device 323 is composed of two thickness detection probes installed on both sides of the middle suction cup and a thickness detection probe installed on the edge of the frame. The three probes simultaneously detect the thickness of the vacuum insulation panel. If the thickness detection value deviation exceeds the set value, the vacuum insulation panel is judged to be a leaking unqualified product, and then it is removed.

[0067] like Figure 4 As shown in (a) and (b), when the vacuum insulation panel is not leaking, the entire surface is very flat and the overall thickness is basically constant; if the vacuum insulation panel is leaking, air enters the aluminum foil bag, and the surface of the aluminum foil bag will bulge, forming a situation where the edges are thin and the middle is thick. By detecting the thickness of the middle and edges, it can be determined whether the vacuum insulation panel is leaking.

[0068] The short side folding device 4 comprises a short side vertical folding mechanism 41 and a short side horizontal folding mechanism 42 .

[0069] like Figure 1 and Figure 5 As shown, the short side vertical folding mechanism 41 is vertically arranged, the tail of the short side vertical folding mechanism 41 is a vertical quadrilateral, the head is a triangle with an inclination, and the edge has an arc to prevent damage to the vacuum insulation panel. It includes a vertical folding head and a vertical cylinder connected to the vertical folding head, and the vertical cylinder controls the vertical folding head to rise and fall to achieve vertical folding.

[0070] Furthermore, the short side transverse folding mechanism 42 includes a transverse folding head and a cylinder connected thereto, and is moved by the extension and contraction of the cylinder. The height of the short side transverse folding mechanism 42 is adjusted and matched according to the thickness of the vacuum insulation panel. The transverse folding head of the short side transverse folding mechanism 42 and the vertical folding head of the short side vertical folding mechanism 41 intersect with each other to fold the short side; the tail of the short side transverse folding mechanism 42 is a transverse quadrilateral, the head is a triangle with an inclination, and the side edges are curved to prevent damage to the vacuum insulation panel.

[0071] The short side vertical folding mechanism 41 and the short side horizontal folding mechanism 42 are respectively arranged in two sets opposite to each other, the inclined edges of the vertical folding heads of the two short side vertical folding mechanisms are located on the inner side, and the inclined edges of the heads of the two short side horizontal folding mechanisms are located on the lower surface. The distance between the two sets of short side folding devices 4 is adjusted and matched according to the size of the empty insulation board.

[0072] The long side corner folding device 5 includes a plate fixing mechanism 51 , a corner folding robot 52 , a corner folding auxiliary mechanism 53 , a long side corner folding mechanism 54 , and a corner arranging mechanism 55 .

[0073] like Figure 1 As shown, the plate fixing mechanism 51 is installed on both sides of the lifting output device 6 to fix the vacuum insulation panel from both sides after the short side folding is completed. There are four corner folding robots 52, which are installed at the four corners of the long side folding area, corresponding to the four corners of the vacuum insulation panel. There are four corner folding auxiliary mechanisms 53, which are installed on the inner side of the four corner folding robots 52, corresponding to the roots of the four corners of the vacuum insulation panel. The long side folding mechanism 54 is installed in the middle of the four corner folding robots 52, corresponding to the two long sides of the vacuum insulation panel.

[0074] like Figure 1 As shown, the plate fixing mechanism 51 adopts a rotary cylinder, which can rotate and move up and down to fix the vacuum insulation panel. The corner folding robot 52 clamps the four corners of the vacuum insulation panel through a manipulator and turns the corner. The corner folding auxiliary mechanism 53 adopts a clamping cylinder, which clamps and tidies the root of each corner before folding the corner to ensure that the root is flat, so that the corner folding robot 52 can clamp and fold the corner.

[0075] Furthermore, if Figure 6 As shown, the long side folding mechanism 54 includes a long side vertical folding mechanism 542 and a long side vertical lifting cylinder 541 connected to the long side vertical folding mechanism 542, a long side horizontal folding mechanism 543 and a long side horizontal folding cylinder 544 connected to the long side horizontal folding mechanism 543. The corner finishing mechanism 55 adopts a small cylinder, and the cylinder rod head is designed with a corner finishing structure to achieve the finishing of the four corners of the vacuum insulation panel, ensure the flatness of the four sides after the corner folding, and avoid corner protrusion.

[0076] The long side vertical folding mechanism 542 is installed at the head of the long side lifting cylinder 541, and the cylinder controls the vertical movement of the long side vertical folding mechanism 542 by telescoping. The long side transverse folding mechanism 543 is installed at the head of the long side transverse folding cylinder 544, and the cylinder controls the transverse reciprocating movement of the long side transverse folding mechanism 543 by telescoping.

[0077] Furthermore, the tails of the long side vertical folding mechanism 542 and the long side horizontal folding mechanism 543 are quadrilateral, the heads are triangular with an inclination, and the side edges are curved to prevent damage to the vacuum insulation panel.

[0078] Furthermore, the head of the long side vertical folding mechanism 542 and the head of the horizontal folding mechanism 543 are used in a cross-coordinated manner to perform long side folding.

[0079] Furthermore, the number of corner finishing mechanisms 55 is four and they are installed on both sides of the transverse folding mechanism 543, corresponding to the roots of the four corners of the vacuum insulation panel. Figure 7 As shown, the angle adjustment mechanism 55 includes a corner adjustment mold 551 and a corner adjustment cylinder 552, which are installed on both sides of the long side transverse folding mechanism 543, corresponding to the positions of the four corners of the vacuum insulation panel. When the vacuum insulation panel is folded, the four corners of the vacuum insulation panel will bulge due to the overlap of bags due to the folding. The function of the corner adjustment structure is to squeeze and adjust the bulging corners to make the corners smoother.

[0080] like Figure 8 As shown, the lifting output device 6 includes a lifting base 61, a lifting linear guide 62, a lifting cylinder 63, a lifting platform 64, a lifting conveyor belt 65, and a lifting transmission motor 66. The lower ends of the lifting linear guide 62 and the lifting cylinder 63 are installed on the lifting base 61, the upper ends of the lifting linear guide 62 and the lifting cylinder 63 are connected to the lifting platform 64, and the lifting conveyor belt 65 and the lifting transmission motor 66 are installed on the lifting platform 64. The lifting transmission motor 66 controls the operation of the lifting conveyor belt 65. The lifting cylinder 63 controls the lifting platform 64 to move axially along the lifting linear guide 62 by telescopic control, and then controls the rise and fall of the lifting conveyor belt 65, so as to realize the function of the lifting output device 6 to output the vacuum insulation panel to the next process. A through hole is set on the workbench 7 for the lifting output device 6 to pass through.

[0081] like Fig. 9 As shown, the long-side corner folding device 5 also includes a long-side corner folding operation platform 56, which includes a plurality of support frames whose upper surfaces are located at the same horizontal plane, and the support frames are arranged between the lifting and conveying belts 65. When the corner folding is performed, the lifting and output device 6 is below the long-side corner folding operation platform 56. After the corner folding is completed, the lifting and output device 6 is lifted higher than the long-side corner folding operation platform 56, so that the lifting and output device can lift the vacuum insulation panel and transport it.

[0082] In the present invention, the positioning device realizes the positioning of a single vacuum insulation panel. The role of positioning is: because the running trajectory of the material transport robot device 3 is set, it can only run along the set route. Only after the vacuum insulation panel is positioned by the positioning device 1 first, can the material transport robot device 3 ensure that it grabs the correct position of the vacuum tube insulation panel. Only when the positioning starting point is accurate, can the material transport robot device 3 ensure that the subsequent running trajectory is correct. The subsequent gluing device 2 and the short edge folding device 3 are both fixed positions. Only when the running trajectory is correct can it be ensured that the colloid is sprayed on the correct position of the vacuum insulation panel during the gluing process, and can it be ensured that the vacuum insulation panel is accurately placed in the short edge folding device 3.

[0085] Embodiment 2: A method for automatically folding corners and edges of a vacuum insulation panel

[0086] The folding and hemming provided by the present invention is for the outer protective bag of the vacuum insulation panel, and an aluminum foil bag is commonly used. The four sides of the aluminum foil bag are sealed, and the seal has a certain width, and the bag as a whole must be larger than the size of the core material. The specific process of folding and hemming is to first fold the short sides of the aluminum foil bag on both sides to make the short sides fit the core material. In the process of folding the short sides, the four corners will protrude. The long sides of the other two sides of the aluminum foil bag are folded to tidy up the protruding corners, and then the long sides are folded to fit the core material, so that the aluminum foil bag is the same size as the core material. The material transport robot device 3 grabs the vacuum insulation panel from the positioning device 1 and sends it to the short side folding device 4. It will pass through the gluing device 2. At the same time, the gluing device applies glue to both sides of the vacuum insulation panel. Therefore, the vacuum insulation panel is moving during gluing, instead of being placed on a certain structure and fixed before gluing. This reduces the movement of the material transport robot device and improves production efficiency.

[0087] When folding the short side, the vacuum insulation panel is placed on the integrated operating platform workbench 7. When folding the corners and folding the long side, the vacuum insulation panel is placed on the long side corner folding and edge folding operating platform 56. In the process of folding the corners and edges of the device, it is not necessary to turn the insulation panel over, and all the folded edges, corners, etc. are placed on the upper surface of the vacuum insulation panel.

[0088] Specifically, the method for automatically folding corners and edges of a vacuum insulation panel is as follows:

[0089] S1, the vacuum insulation panel enters the positioning device through the input conveyor mechanism for positioning;

[0090] S2, the material transport robot performs air leakage detection on the positioned vacuum insulation panels and removes unqualified panels, and places qualified panels on the short-side folding device;

[0091] S3, the gluing device applies glue to the two short sides of the vacuum insulation panel during the placement process for bonding and fixing after folding; the short folding device folds and fixes the short sides;

[0092] S4, the material transport robot places the vacuum insulation panel with the short side folded on the long side corner folding and edge folding device; the gluing device applies glue to the two long sides of the vacuum insulation panel during the placement process for bonding and fixing after folding; the long side corner folding and edge folding device first folds the long side and then folds the edge, so as to achieve the corner folding and edge folding of the vacuum insulation panel;

[0093] S5, the lifting output device outputs the vacuum insulation panel with the corner and edge folding completed to the automatic corner and edge folding equipment.

[0094] The above contents can be implemented individually or in combination in various ways, and these variations are all within the protection scope of the present invention.

[0095] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
