Description

Technical Field

[0001] The invention relates to the technical field of modular integrated house frame skin assembly, and in particular to an edge binding device and edge binding equipment. Background Art

[0002] In recent years, the state and local governments have successively issued a series of policies to promote prefabricated buildings, clearly requiring the assembly rate of new buildings. Various companies have successively carried out research on prefabricated buildings and completed some preliminary research and engineering cases of prefabricated buildings. Modular integrated houses are a form of building with a high degree of prefabrication that conforms to the form of prefabricated buildings. This type of building is a building structure that uses a single room as a prefabricated component unit, which is prefabricated in the factory and then transported to the construction site for installation. The development history of integrated houses in my country is relatively short and the development speed is relatively slow. A large number of processes in prefabricated production factories are carried out manually, with a low degree of automation and uneven product quality.

[0003] At present, the finished frame products used in some modular integrated houses include an upper frame and a skin covering the upper frame. The frame is 6m long and 3m wide. The skin edging is done manually. It takes 3 to 4 people to complete the skin edging of a single frame. The completion speed is 8 to 9 minutes or even longer, which is inefficient and has high labor costs. The edging is done manually by pushing, smashing and warping with a shovel-type tool. The skin precision is low and the flange lengths are uneven, so the skin effect is not good. Summary of the invention

[0051] In order to illustrate the technical solution of the present invention, the following is a description with reference to specific drawings and embodiments.

[0052] The present application provides an edge wrapping device and an edge wrapping equipment having the edge wrapping device, which are used for wrapping a skin on a frame, wherein the frame can be an upper frame of a modular integrated house.

[0053] Please refer to Figures 1 to 3 The skin 3 is used to cover at least one edge to be covered of the frame 2. In this embodiment, the frame 2 is rectangular, and the inner edge of the frame 2 is provided with an edge to be covered, and the edge to be covered includes two long straight edges 201, two short straight edges 202 and four corner edges 203. The long straight edges 201 and the short straight edges 202 are perpendicular to each other, and each corner edge 203 is obliquely connected between the long straight edges 201 and the short straight edges 202. Optionally, the ends of the edges to be covered are suspended and extend downward at a preset angle to the horizontal plane. In this embodiment, the preset angle between the ends of the edges to be covered and the horizontal plane is 15°.

[0054] In other embodiments, the structure of the frame 2 is not limited thereto. For example, the lengths of the four straight sides are equal, or the inner edge of the frame 2 is only provided with four straight sides without the corner edges 203 .

[0055] Please refer to Figures 1 to 5 Before the hemming, the skin 3 is in a flat plate shape. Optionally, the skin 3 is a 0.3 mm thick galvanized steel plate. After the hemming, the skin 3 is wrapped around the two long straight edges 201, the two short straight edges 202 and the four corner edges 203, and fits with the corresponding edges.

[0056] Please refer to Figures 1 to 8 The hemming equipment 1 provided in the embodiment of the present application includes a mounting frame 200 and an hemming device 100 arranged on the mounting frame 200 , and the hemming device 100 is used to cover the skin 3 on the frame 2 .

[0057] Optionally, there are multiple edge wrapping devices 1, and multiple edge wrapping devices 100 are sequentially arranged along the side of the mounting frame 200, and the long straight side 201, the short straight side 202 and the corner side 203 of the frame 2 each correspond to at least one edge wrapping device 100. It can be understood that the number of edge wrapping devices 1 can also be one, in which case the edge wrapping device 100 can move along the mounting frame 200, and can also bend the entire edge of the skin 3.

[0058] Optionally, the mounting frame 200 can be placed on a fixed plane and placed horizontally; the hemming device 1 further includes a mobile assembly platform 300, which is used to move the skin 3 and the frame 2 to the installation position corresponding to the mounting frame 200, wherein the skin 3 is placed above the frame 2. Optionally, the mobile assembly platform 300 is an RGV platform, but is not limited thereto.

[0059] Please refer to Figure 7 and Figure 8 The edge binding device 100 proposed in one embodiment of the present application includes a lifting mechanism 10, an edge finding mechanism 20 and a flip edge binding mechanism 30.

[0060] The lifting mechanism 10 includes a lifting drive 11 disposed on the mounting frame 200 and a pressing bottom plate 12 connected to the lifting drive 11. The lifting drive 11 is used to drive the pressing bottom plate 12 to move up and down relative to the mounting frame 200, that is, the lifting drive 11 is used to drive the pressing bottom plate 12 to move toward or away from the skin 3. The pressing bottom plate 12 is used to press the skin 3. The pressing bottom plate 12 can be in the shape of a flat plate, so that the pressing bottom plate 12 can be closely attached to the skin 3.

[0061] The edge-finding mechanism 20 is disposed on the pressing bottom plate 12 and can be raised and lowered together with the pressing bottom plate 12 .

[0062] The flipping and edge wrapping mechanism 30 includes a flipping driving assembly 31 and a bending plate 32. One end of the flipping driving assembly 31 is connected to the edge finding mechanism 20, and the other end is connected to the bending plate 32. The edge finding mechanism 20 is used to drive the flipping and edge wrapping mechanism 30 to move relative to the pressing bottom plate 12 so that the bending plate 32 fits the edge of the skin 3. The flipping driving assembly 31 is used to drive the bending plate 32 to rotate so as to bend the edge of the skin 3 and wrap it on the frame 2.

[0063] The use process of the above-mentioned edge wrapping device 100 is as follows. First, place the skin 3 on the frame 2, and place the skin 3 and the frame 2 under the mounting frame 200. The lifting mechanism 10 drives the pressing base plate 12 to move in the direction close to the skin 3, so that the pressing base plate 12 presses the skin 3 to prevent the skin 3 from moving or bulging during the bending process; the edge-finding mechanism 20 drives the flipping edge wrapping mechanism 30 to move relative to the pressing base plate 12, so that the bending plate 32 fits the edge of the skin 3, and the bending plate 32 performs a preliminary bend on the edge of the skin 3 during the movement; then, the flipping drive assembly 31 drives the bending plate 32 to rotate, and the bending plate 32 further bends the skin 3 and wraps it on the frame 2.

[0064] In one embodiment, the bending plate 32 is spaced apart from the clamping base plate 12, and in an initial state, the bending surface of the bending plate 32 is inclined relative to the vertical direction. Therefore, when the edge-finding mechanism 20 drives the bending plate 32 to move, the bending plate 32 can perform a preliminary bend on the edge of the skin 3; it can be understood that if the bending surface of the bending plate 32 is horizontally arranged in the initial state, the bending plate 32 can rotate and bend the skin 3 under the drive of the flipping drive assembly 31, without the need for a preliminary bend during the edge-finding process.

[0065] It can be understood that the angle at which the bending plate 32 bends the skin 3 can be set as needed. For example, the bending plate 32 bends the edge of the skin 3 by 60°, 90°, 120°, 180°, etc.

[0066] The above-mentioned edging device 100 includes a lifting mechanism 10, an edge-finding mechanism 20 and a flipping edging mechanism 30. The lifting mechanism 10 includes a lifting drive 11 and a clamping base plate 12 arranged on the mounting frame 200. The lifting drive 11 is used to drive the clamping base plate 12 and the edge-finding mechanism 20 and the flipping edging mechanism 30 arranged on the clamping base plate 12 to lift and lower, so that the clamping base plate 12 presses the skin 3; the edge-finding mechanism 20 is used to drive the flipping edging mechanism 30 to move on the clamping base plate 12, so that the bending plate 32 moves toward the direction close to the skin 3; the flipping drive assembly 31 in the flipping edging mechanism 30 can drive the bending plate 32 to rotate, so that the edge of the skin 3 is bent and wrapped on the frame 2. Therefore, the above-mentioned edging device 100 can automatically bend the skin 3 and cover the skin 3 on the frame 2, with a high degree of automation, replacing the manual edging operation, improving the efficiency of edging and reducing labor costs; the skin 3 can be flanged into place through the edge-finding mechanism 20 and the flipping edging mechanism 30, solving the problem of uneven flange lengths and improving the effect of the skin 3.

[0067] In one embodiment, the edge-finding mechanism 20 includes a horizontal edge-finding driving member 21 and an edge-finding bottom plate 22 connected to each other, one end of the flip driving assembly 31 is connected to the edge-finding bottom plate 22, and the horizontal edge-finding driving member 21 is fixed to the pressing bottom plate 12 and is used to drive the edge-finding bottom plate 22 and the flip edge-binding mechanism 30 to move horizontally. The horizontal edge-finding driving member 21 can be a cylinder, but is not limited thereto. For example, the horizontal edge-finding driving member 21 can also be a driving member such as an oil cylinder or a ball screw. The horizontal edge-finding driving member 21 can drive the edge-finding bottom plate 22 and the flip edge-binding mechanism 30 disposed on the edge-finding bottom plate 22 to move horizontally, so that the bending plate 32 gradually approaches until it abuts against the edge of the skin 3. In the process of horizontal edge-finding, the bending plate 32 can perform a preliminary bend on the edge of the skin 3. In other embodiments, the edge-finding bottom plate 22 can be omitted, and the horizontal edge-finding driving member 21 can be directly connected to the flip edge-binding mechanism 30 to drive the flip edge-binding mechanism 30 to move.

[0068] In one embodiment, the edge-finding mechanism 20 also includes a connecting corner block 23 and an inclined edge-finding driving member 24; the connecting corner block 23 is movably arranged on the clamping base plate 12 and is connected to the driving end of the horizontal edge-finding driving member 21, and the surface of the connecting corner block 23 away from the clamping base plate 12 is an inclined surface inclined to the clamping base plate 12; the inclined edge-finding driving member 24 is arranged on the inclined surface and connected to the edge-finding base plate 22, and the inclined edge-finding driving member 24 is used to drive the edge-finding base plate 22 and the flipping edge wrapping mechanism 30 to move along a direction parallel to the inclined surface.

[0069] Optionally, the surface of the clamping base plate 12 is horizontally arranged, and the angle between the inclined surface and the clamping base plate 12 is 15°, that is, the angle between the inclined surface and the clamping base plate 12 is equal to the angle between the end of the edge to be covered of the frame 2 and the horizontal plane.

[0070] The tilting edge-finding driving member 24 may be a cylinder, but is not limited thereto. For example, the horizontal edge-finding driving member 21 may also be a driving member such as an oil cylinder or a ball screw.

[0071] In this embodiment, since the edge-finding mechanism 20 includes a horizontal edge-finding driving member 21, a connecting corner block 23, an inclined edge-finding driving member 24 and an edge-finding bottom plate 22, the horizontal edge-finding driving member 21 can drive the edge-finding bottom plate 22 to move horizontally, and the inclined edge-finding driving member 24 can drive the edge-finding bottom plate 22 to move obliquely, so that the bending plate 32 can move horizontally and obliquely, and can preliminarily bend the edge of the skin 3 during the edge-finding process. By simultaneously providing the horizontal edge-finding driving member 21 and the inclined edge-finding driving member 24, the automatic edge-finding of the bending plate 32 in the extension and retraction directions of the two cylinders is realized, and there is a certain adaptability to the size error and positioning error of the frame 2.

[0072] In one embodiment, the flip drive assembly 31 includes a first bending drive member 311 and a connecting bottom plate 312. The edge-finding bottom plate 22, the first bending drive member 311 and the connecting bottom plate 312 form a triangular structure, that is, the edge-finding bottom plate 22 and the first bending drive member 311, the first bending drive member 311 and the connecting bottom plate 312, and the edge-finding bottom plate 22 and the connecting bottom plate 312 are all connected at a certain angle. A hinge 221 is provided at the end of the edge-finding bottom plate 22, the connecting bottom plate 312 includes a first end 3121 and a second end 3122 that are arranged opposite to each other, and the bending plate 32 is arranged at the second end 3122.

[0073] One end of the first bending drive member 311 is connected to the edge-finding base plate 22, and the other end is hinged to the first end 3121 of the connecting base plate 312; the second end 3122 of the connecting base plate 312 is rotatably connected to the hinge part 221, and the first bending drive member 311 can move telescopically to drive the connecting base plate 312 to rotate around the hinge part 221, thereby driving the bending plate 32 on the connecting base plate 312 to rotate.

[0074] By adopting the above technical solution, the first bending drive member 311 can move with the edge-finding base plate 22 to find the edge, and can drive the connecting base plate 312 and the bending plate 32 to rotate. During the rotation of the bending plate 32, the edge of the skin 3 can be bent to cover the skin 3 on the frame 2.

[0075] Furthermore, in one embodiment, the flip driving assembly 31 further includes a second bending driving member 313 disposed on the connecting bottom plate 312, one end of the bending plate 32 is hinged to the driving end of the second bending driving member 313, and the other end is hinged to the second end 3122 of the connecting bottom plate 312; the driving end of the second bending driving member 313 can perform telescopic movement along a direction parallel to the connecting bottom plate 312 to drive the bending plate 32 to rotate relative to the second end 3122 of the connecting bottom plate 312. The bending plate 32, the second bending driving member 313 and the connecting bottom plate 312 form a triangular structure through the hinge.

[0076] Optionally, the first bending driving member 311 and the second bending driving member 313 are both cylinders, the first bending driving member 311 serves as a primary cylinder, and the second bending driving member 313 serves as a secondary cylinder, which can respectively drive the bending plate 32 to rotate.

[0077] By adopting the above technical solution, the above-mentioned flipping and hemming mechanism 30 can rotate the bending plate 32 twice, avoiding the problem of small torque caused by a single driving component, and has a simple structure and a stable driving effect.

[0078] It can be understood that the first bending driving member 311 and the second bending driving member 313 can also be other driving members such as a cylinder and a ball screw.

[0079] In other embodiments, the second bending driving member 313 may also be replaced by a connecting rod, so that the bending plate 32 is fixedly connected to the connecting base plate 312 via the connecting rod.

[0080] In one embodiment, the bending plate 32 includes a first strip plate 321 and a second strip plate 322 obliquely connected to the middle of the first strip plate 321. The first strip plate 321 is used to fit and bend the skin 3. The length of the first strip plate 321 is the length of the skin 3 that can be bent in each action.

[0081] A first pivot portion is provided on the side of the first strip plate 321 away from the first strip plate 321, and the bending plate 32 is hinged to the hinge portion 221 of the edge-finding bottom plate 22 through the first pivot portion; a second pivot portion is provided on the side of the second strip plate 322 away from the first strip plate 321, and the bending plate 32 is hinged to the driving end of the second bending driving member 313 through the second pivot portion.

[0082] By adopting the above technical solution, the two ends of the bending plate 32 can be rotatably connected to the edge-finding bottom plate 22 and the second bending driving member 313 respectively, and the surface of the first strip plate 321 can be set to a plane to facilitate bending the skin 3.

[0083] In this embodiment, the second end 3122 of the connecting base plate 312 and the first pivot portion are both rotatably connected to the hinge portion 221 at the end of the edge-seeking base plate 22. For example, the hinge portion 221 includes a hinge seat with a hinge hole and a hinge shaft passing through the hinge hole, and the hinge shaft is simultaneously passed through the second end 3122 of the connecting base plate 312 and the first pivot portion.

[0084] In one embodiment, the edge-finding bottom plate 22 includes a vertically connected connecting plate 222 and a mounting plate 223. The connecting plate 222 is arranged on the side of the inclined edge-finding driving member 24 away from the flip edge-binding mechanism 30, and the mounting plate 223 is arranged obliquely relative to the pressing bottom plate 12. One end of the pressing bottom plate 12 is provided with an avoidance opening, and one end of the mounting plate 223 facing the bending plate 32 is movably inserted into the avoidance opening. By adopting the above technical solution, when the pressing bottom plate 12 presses the middle part of the skin 3, the end of the mounting plate 223 can pass through the avoidance opening and press the edge of the skin 3 to prevent the skin 3 from moving or bulging.

[0085] like Figure 8 As shown, the connecting plate 222 is located on the side of the inclined edge-finding driving member 24 away from the flipping edge-binding mechanism 30 . It can be understood that the connecting plate 222 can also be arranged on the side of the inclined edge-finding driving member 24 facing the flipping edge-binding mechanism 30 .

[0086] In one embodiment, the lifting mechanism 10 further includes a lifting bracket 13, the two ends of which are respectively connected to the driving end of the lifting drive member 11 and the end of the pressing bottom plate 12, and the flip driving assembly 31 is partially inserted into the lifting bracket 13. By adopting the above technical solution, the lifting bracket 13 plays the role of connecting the lifting drive member 11 and the pressing bottom plate 12, and the lifting bracket 13 is a hollow bracket, which is convenient for inserting the first bending drive member 311. In other embodiments, the lifting bracket 13 can also be replaced by a connecting structure such as a connecting rod.

[0087] In one embodiment, the edging equipment 1 provided in the present application includes a mounting frame 200 and an edging device 100 of any of the above-mentioned embodiments. The edging device 100 is arranged on the mounting frame 200 and is used to perform edging operations on the skin 3 and the frame 2 below the mounting frame 200.

[0088] Optionally, there are multiple edge wrapping devices 100, and the multiple edge wrapping devices 100 are sequentially arranged along the side of the mounting frame 200, that is, each of the long straight side 201, the short straight side 202 and the corner side 203 of the frame 2 is correspondingly provided with at least one edge wrapping device 100. In this way, the multiple edge wrapping devices 100 can bend the skin 3 at the same time.

[0089] Optionally, the mounting frame 200 is a rectangular hollow frame 2, and the edging device 100 is arranged on the inner side of the mounting frame 200. Adjacent bending plates 32 may have a small gap or be in contact with each other. In this way, multiple edging devices 100 can operate simultaneously to bend the entire side edge of the skin 3, and the skin 3 is not easily torn.

[0090] In order to adapt to the lengths of the long straight edge 201, the short straight edge 202 and the corner edge 203, the lengths of the bending plates 32 used in the flipping and hemming mechanisms 30 corresponding to the long straight edge 201, the short straight edge 202 and the corner edge 203 are different, so that the number of flipping and hemming mechanisms 30 corresponding to the long straight edge 201, the short straight edge 202 and the corner edge 203 is an integer. In this embodiment, the length of the bending plate 32 in the flipping and hemming mechanism 30 corresponding to the long straight edge 201 is greater than the length of the flipping and hemming mechanism 30 corresponding to the short straight edge 202. Optionally, the length of the flipping and hemming mechanism 30 corresponding to the short straight edge 202 is greater than the length of the flipping and hemming mechanism 30 corresponding to the corner edge 203.

[0091] The following is an example to illustrate the use principle of the hemming device 1 .

[0092] In this embodiment, the hemming device 1 includes a mounting frame 200, and a plurality of hemming devices 100 are respectively provided on the long sides and short sides of the mounting frame 200, and a hemming device 100 is respectively provided on the corner sides 203 of the frame 2 of the mounting frame 200. Each hemming device 100 includes a lifting mechanism 10, an edge finding mechanism 20, and a flip hemming mechanism 30.

[0093] The lifting mechanism 10 includes a lifting drive 11 disposed on the mounting frame 200, a lifting bracket 13 connected to the lifting drive 11, and a pressing base plate 12 vertically connected to the lifting bracket 13. The lifting drive 11 is used to drive the pressing base plate 12 to rise and fall relative to the mounting frame 200, that is, to move in the vertical direction. The edge-finding mechanism 20 is disposed on the pressing base plate 12, and includes a horizontal edge-finding drive 21 disposed on the pressing base plate 12, a connecting angle block 23 connected to the horizontal drive, an inclined edge-finding drive 24 disposed on the connecting angle block 23, and an edge-finding base plate 22. The flip edge-wrapping mechanism 30 includes a first bending drive 311, a connecting base plate 312, a second bending drive 313, and a bending plate 32.

[0094] The method of using the hemming device 1 includes the following steps.

[0095] Please refer to Figures 1 to 10 First, the frame 2 and the skin 3 are positioned on the mobile assembly platform 300 , and the mobile assembly platform 300 moves and positions the skin 3 and the frame 2 under the mounting frame 200 .

[0096] Next, the lifting drive members 11 of all the flipping and hemming mechanisms 30 arrayed along the long straight edges 201 and the short straight edges 202 extend out, driving all the corresponding flipping and hemming mechanisms 30 to press down, pressing the bottom plate 12 and the skin 3, so that it will not move or bulge when folding.

[0097] Then, the horizontal edge-finding driving member 21 retracts, driving the inclined edge-finding driving member 24 and other components thereon to move horizontally. At this time, the edge-finding bottom plate 22 presses the skin 3 corresponding to the long straight edge 201 and the short straight edge 202 onto the inner edge of the frame 2 inclined at 15°, and the bending plate 32 is pulled horizontally, contacts the edges of the skin 3 corresponding to the long straight edge 201 and the short straight edge 202 and slides on the edges of the skin 3; after the horizontal edge-finding driving member 21 stops retracting, the inclined edge-finding driving member 24 extends out, driving the components connected thereto to move in a direction of 15° to the horizontal. At this time, the bending plate 32 continues to be pulled and slides on the edges of the skin 3 corresponding to the long straight edge 201 and the short straight edge 202. The edges of the skin 3 are deformed and bent downward after being pressed by the bending plate 32, as shown in FIG. Fig. 9 and Fig.10 As shown, the edge-wrapping device 1 is in the first state at this time.

[0098] Next, please refer to Fig.11 and Fig.12 The first bending drive member 311 extends out to drive the connecting bottom plate 312 together with the second bending drive member 313 and the bending plate 32 thereon to make the first rotation. During the rotation process, the inclined edge-finding drive member 24 is appropriately retracted and adjusted under the action of force, so that the bending plate 32 is always close to the skin 3 and the hemming edge of the frame 2 corresponding to the long straight edge 201 and the short straight edge 202. At the same time, it can ensure that the bending plate 32 can rotate normally. After rotating to a certain angle, the first bending drive member 311 has not yet reached the maximum extension stroke. Affected by the structure of the bending plate 32, the hinged portion 221 is pressed tightly on the skin 3. Fig.12 As shown, at this time, the edge-wrapping device 1 is in the second state.

[0099] Then, please refer to Fig.13 and Fig.14 The inclined edge-finding driving member 24 retracts and drives the components connected thereto to move downward along an inclination of 15°. The bending plate 32 releases the skin 3. The first bending driving member 311 reaches the maximum extension stroke, and the bending plate 32 continues to rotate a certain angle. At this time, the edge-binding equipment 1 is in the third state.

[0100] Next, please refer to Fig.15 and Fig.16The second bending drive member 313 extends out to drive the bending plate 32 to continue rotating. The bending plate 32 continues to contact the edge of the skin 3 bent at a certain angle and continues to slide on it. The edge of the skin 3 continues to be folded and deformed under the support of the inner edge of the frame 2. Finally, the bending plate 32 is pressed tightly under the inner edge of the skin 3 and the frame 2. At this time, the hemming device 1 is in the fourth state.

[0101] Under the condition that the bending plates 32 of the flip edge wrapping mechanism 30 corresponding to the long straight edge 201 and the short straight edge 202 continue to be pressed, the lifting driving members 11 of the flip edge wrapping mechanism 30 corresponding to the four corner edges 203 extend, driving the four pressing bottom plates 12 to press down, and then the horizontal edge-finding driving members 21 of the flip edge wrapping mechanism 30 of the four corner edges 203 retract, and the inclined edge-finding driving members 24 extend, driving the bending plate 32 to bend the skin 3 corresponding to the diagonal edge 203 once, and then the first bending driving member 311 extends to drive the bending plate 32 The skin 3 corresponding to the rotating diagonal edge 203 is bent twice. At this time, the skin 3 corresponding to the corner edge 203 and the double-layer structure formed by folding the straight edges at both ends have formed a fold at a certain angle. Then the first bending drive member 311 of the flipping and hemming mechanism 30 of the corner edge 203 retracts, and the bending plate 32 corresponding to the corner edge 203 loosens the skin 3. The first bending drive member 311 and the second bending drive member 313 of all the flipping and hemming mechanisms 30 of the long straight edge 201 and the short straight edge 202 retract, and the horizontal edge-finding drive member extends.

[0102] Next, the flipping and hemming mechanisms 30 corresponding to all the corner edges 203 continue to complete the folding of the skins 3 of the four corner edges 203 (i.e., extending from the first bending drive member 311 to the second bending drive member 313) according to the previous hemming action of the flipping and hemming mechanisms 30 corresponding to the long straight edges 201 and the short straight edges 202. After the skins 3 corresponding to the corner edges 203 are folded and formed, the first bending drive members 311 and the second bending drive members 313 of the flipping and hemming mechanisms 30 corresponding to the four corner edges 203 retract, and the horizontal edge-finding drive member 21 extends. Finally, the lifting and lowering drives 11 of all the flipping and hemming mechanisms 30 retract, and the edge-finding mechanism 20 and the flipping and hemming mechanism 30 are lifted.

[0103] At this point, a working cycle of the entire hemming device 1 is completed, and the mobile assembly platform 300 transfers the upper frame 2 (finished product) with completed skin hemming to the next production station.

[0104] In the above embodiment, since the hemming device 100 bends the skin 3 at three angles, it is convenient to adjust the sizes of the three angles to make the hemming operation more refined. It can be understood that the flip hemming mechanism 30 can also be a structure of a robot tool head to bend the skin 3 in sections multiple times at multiple angles.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
