[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0022] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0023] refer to Figures 1 to 5 The embodiment of the present application discloses a folding device for folding a foldable object. The foldable object may be a whole plate, or at least two plates connected by rotation, or a rod, etc. The foldable object may be folded into a desired shape by the folding device. The disclosed folding device includes a bracket 10 and a bending mechanism 20.

[0024] The bracket 10 is a basic component, and the bracket 10 can carry the folded piece. In some embodiments, the bracket 10 has a first support portion and a second support portion, and the first support portion and the second support portion are spaced apart in the first direction. The first support portion is used to support one end of the folded piece, and the second support portion is used to support the other end of the folded piece. In this way, the bracket 10 can achieve stable support for the folded piece. In addition, the bracket 10 can also provide an installation and bearing foundation for the bending mechanism 20.

[0025] The bending mechanism 20 is used to apply a folding force to the folded member so that the folded member can be bent and deformed to form a preset shape. Figure 2 As shown, the bending mechanism 20 includes a first driving component 21 and a force-applying component 22, wherein the force-applying component 22 is used to apply a force to the area between the two ends of the folded piece, and the first driving component 21 is connected to the force-applying component 22, and is used to apply a force to the area between the two ends of the folded piece through the force-applying component 22, so as to bend and deform the folded piece. Optionally, the force-applying component 22 can apply a clamping force, a snap-fitting force, a squeezing force, etc. to the area between the two ends of the folded piece, as long as it can apply a force that can bend and deform the folded piece, and the specific form is not limited.

[0026] It should be noted that the two ends of the foldable member are supported by the first support portion and the second support portion respectively, so that the foldable member can be regarded as a lever, and when the area between the two ends is subjected to a force, the foldable member will bend and deform. For example, the foldable member can be a plate, and the two ends of the plate are supported, and when the middle area is subjected to a force, the plate will bend.

[0027] Compared with the manual method of bending the foldable parts, the embodiment of the present application uses a folding device to replace the manual method, which can greatly reduce the labor required for manual bending and improve the bending efficiency; in addition, since the staff will get tired after working for a long time, the manual method cannot continuously output the same force for a long time, which easily leads to different degrees of bending of different foldable parts, so that a batch of products formed after bending have different specifications, which leads to low bending accuracy of the foldable parts. The folding device in the embodiment of the present application will not feel tired due to long-term work like the staff, so it can continuously output the same folding force for a long time, so that the bending specifications of the foldable parts are the same (that is, the specifications of the products formed after bending are the same), thereby ensuring the bending accuracy of the products.

[0028] refer to Figure 2 and Figure 3 In some embodiments, the first driving assembly 21 may include a first driving member 211, and the first driving member 211 is connected to the force-applying assembly 22, and is used to drive the force-applying assembly 22 to move in the second direction. Based on this configuration, under the driving force of the first driving member 211, the force-applying assembly 22 can drive the folded member to move in the second direction, and because the two ends of the folded member are supported by the first support portion and the second support portion respectively, the area between the two ends of the folded member can be bent and deformed, so that the folded member forms a preset shape.

[0029] Optionally, the first driving member 211 may be a linear driving module, such as a cylinder, a hydraulic cylinder, an electric cylinder, a screw and a slider, etc. Of course, it may also be in other forms, which are not specifically limited here.

[0030] In addition, the first direction and the second direction may be perpendicular to each other, and of course, may be at other angles, as long as the bending requirements can be met, and the specific angles are not limited. For example, the first direction may be a horizontal direction, and the second direction may be a vertical direction.

[0031] In the embodiment of the present application, the first driving assembly 21 may further include a moving seat 212, such as Figure 3 As shown, the moving seat 212 is connected to the driving end of the first driving member 211, and the force-applying assembly 22 is disposed on the moving seat 212. Based on this, the first driving member 211 can drive the force-applying assembly 22 to move in the second direction through the moving seat 212.

[0032] Continue to refer Figure 2In some embodiments, the force applying assembly 22 may include a second driving member 221, a first clamping member 222, and a second clamping member 223. The second driving member 221 is connected to the first clamping member 222 and the second clamping member 223, respectively, and is used to drive the first clamping member 222 and the second clamping member 223 to move relatively closer or farther away in a third direction. The third direction may be perpendicular to the first direction.

[0033] Based on the above arrangement, when it is necessary to apply a force to the piece to be folded, the first clamping member 222 and the second clamping member 223 can first be located on both sides of the piece to be folded in the third direction, and then the first clamping member 222 and the second clamping member 223 can be driven relatively close to each other by the second driving member 221, so that the area between the two ends of the piece to be folded can be clamped from both sides by the first clamping member 222 and the second clamping member 223.

[0034] Subsequently, the first driving component 21 can drive the force-applying component 22 and the area between the two ends of the clamped piece to be folded to move in the second direction. Since the two ends of the piece to be folded are respectively supported by the first supporting part and the second supporting part, the area between the two ends of the piece to be folded can be bent and deformed.

[0035] Optionally, the force-applying assembly 22 can be a clamping cylinder assembly, and accordingly, the second driving member 221 is a cylinder, and the first clamping member 222 and the second clamping member 223 are respectively clamping members; of course, the first driving member 211 can also include a motor and a screw, and the screw has a coaxially arranged forward thread and reverse thread, the first clamping member 222 is transmission-connected to the forward thread, and the second clamping member 223 is transmission-connected to the reverse thread, so that the screw is driven to rotate by the motor, and drives the first clamping member 222 and the second clamping member 223 to be relatively close or relatively far away.

[0036] In order to improve the position accuracy of the folded piece, the folding device may further include a positioning mechanism 30, such as Figure 1 As shown, the positioning mechanism 30 can position the to-be-folded pieces placed on the first support portion and the second support portion. The positioning mechanism 30 can drive the to-be-folded pieces to move in the first direction to adjust the position of the to-be-folded pieces in the first direction.

[0037] refer to Figure 2 and Figure 4In some embodiments, the positioning mechanism 30 may include a third driving member 31, a first positioning member 32, and a second positioning member 33. The first positioning member 32 is disposed on the first supporting portion to realize the bearing and installation of the first positioning member 32 through the first supporting portion; the second positioning member 33 is disposed on the second supporting portion to realize the bearing and installation of the second positioning member 33 through the second supporting portion; the third driving member 31 is connected to at least one of the first positioning member 32 and the second positioning member 33, so that the first positioning member 32 and the second positioning member 33 are relatively close to or relatively far away from each other in the first direction.

[0038] Based on the above arrangement, when the piece to be folded is placed on the first support portion and the second support portion, under the driving action of the third driving member 31, the first positioning member 32 and the second positioning member 33 are relatively close to each other and squeeze the piece to be folded from both sides in the first direction, so that the piece to be folded can be moved in the first direction, thereby realizing the position adjustment of the folding piece in the first direction and ensuring the position accuracy of the piece to be folded in the first direction.

[0039] In some embodiments, the first positioning member 32 can be fixed to the first support portion, and the second positioning member 33 can be slidably disposed on the second support portion. In this case, the third driving member 31 is connected to the second positioning member 33 to drive the second positioning member 33 to move toward or away from the first positioning member 32.

[0040] In other embodiments, the first positioning member 32 can be slidably disposed on the first support portion, and the second positioning member 33 can be fixed to the second support portion. In this case, the third driving member 31 is connected to the first positioning member 32 to drive the first positioning member 32 to move toward or away from the second positioning member 33.

[0041] In some other embodiments, the first positioning member 32 can be slidably set on the first support portion, and the second positioning member 33 can be slidably set on the second support portion. In this case, the third driving member 31 is respectively connected to the first positioning member 32 and the second positioning member 33 to drive the first positioning member 32 and the second positioning member 33 to move toward or away from each other.

[0042] The third driving member 31 may be a linear module, such as a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, etc. Of course, it may also be in other forms, which are not specifically limited here.

[0043] In some more specific embodiments, the third driving member 31 may include a motor and a screw, and the screw has a coaxially arranged forward-spinning thread and a reverse-spinning thread, the first positioning member 32 is transmission-connected to the forward-spinning thread, and the second positioning member 33 is transmission-connected to the reverse-spinning thread. In this way, the screw is driven to rotate by the motor, and the first positioning member 32 and the second positioning member 33 are driven to move toward or away from each other.

[0044] Taking into account that convex arc surfaces are provided at both ends of the piece to be folded, correspondingly, the end surfaces of the first positioning member 32 and the second positioning member 33 that contact the piece to be folded can be provided with concave arc surfaces respectively. In this way, through the cooperation of the convex arc surface and the concave arc surface, the contact area can be increased, thereby improving the contact stability and preventing the positioning accuracy from being affected by poor contact.

[0045] refer to Figure 2 and Figure 4 In some embodiments, the bracket 10 may include a first support platform 11 and a second support platform 12 spaced apart in a first direction, the first positioning member 32 may be disposed on the first support platform 11, and the second positioning member 33 may be disposed on the second support platform 12; in addition, both ends of the member to be folded may be overlapped on the first support platform 11 and the second support platform 12, respectively.

[0046] Furthermore, the first support platform 11 can be provided with a first groove 111, and the bottom of the first groove 111 is the first support portion. The second support platform 12 can be provided with a second groove 121, and the bottom of the second groove 121 is the second support portion. In this way, the two ends of the folded part can be supported respectively by the bottom of the first groove 111 and the bottom of the second groove 121.

[0047] In addition, the first positioning member 32 is disposed in the first groove 111, the second positioning member 33 is disposed in the second groove 121, and at least one of the first positioning member 32 and the second positioning member 33 is movable in the first direction. Based on this, the first positioning member 32 can be limited by the side wall of the first groove 111 to prevent the first positioning member 32 from moving at will, and the second positioning member 33 can be limited by the side wall of the second groove 121 to prevent the second positioning member 33 from moving at will.

[0048] In addition, when the first positioning member 32 is movable, the first groove 111 can guide the first positioning member 32 ; when the second positioning member 33 is movable, the second groove 121 can guide the second positioning member 33 .

[0049] refer to Figure 4 In some embodiments, the folding device may further include a first buffer member 51, which is disposed on at least one of the first positioning member 32 and the second positioning member 33, and is used to contact the bracket 10 when at least one of the first positioning member 32 and the second positioning member 33 moves in the first direction, thereby playing a certain buffering role; of course, when the first buffer member 51 buffers to the extreme buffering position, it can also limit at least one of the first positioning member 32 and the second positioning member 33 to prevent at least one of them from moving excessively.

[0050] Correspondingly, the bracket 10 may be provided with a first blocking portion 112 , and the first blocking portion 112 may block the first buffer member 51 , so that the first buffer member 51 performs buffering and limiting functions when it touches the first blocking portion 112 .

[0051] For example, the first buffer member 51 can be a gas spring, a hydraulic spring, etc., and of course, it can also be in other forms, which are not specifically limited here. In addition, the first blocking portion 112 can be a convex structure, and of course, it can also be in other structures.

[0052] After the folded piece is bent, in order to further deform the folded piece to obtain a final shape, the folding device may further include a forming mechanism 40, such as Figure 1 As shown, the forming mechanism 40 can form the to-be-folded piece that has been bent and deformed by the cooperation between the first driving component 21 and the force-applying component 22 , so that the to-be-folded piece is formed into a desired final shape.

[0053] refer to Figure 2 and Figure 4 In some embodiments, the molding mechanism 40 may include a first molding component 41 and a second molding component 42 spaced apart in a first direction. The first molding component 41 has a first extrusion portion, and the second molding component 42 has a second extrusion portion, and the first extrusion portion and the second extrusion portion are respectively used to extrude the two sides of the to-be-folded piece that is bent and deformed after the force is applied by the force-applying component 22 in the first direction, so as to mold the to-be-folded piece.

[0054] Based on the above arrangement, the first molding component 41 and the second molding component 42 can cooperate with each other to further mold the part to be folded, so that the part to be folded can be formed into a desired final shape.

[0055] Among them, Figure 4 As shown, the first forming assembly 41 may include a fourth driving member 411 and a first extrusion block 412, wherein the fourth driving member 411 is disposed on the bracket 10 and connected to the first extrusion block 412; similarly, the second forming assembly 42 may include a fifth driving member 421 and a second extrusion block 422, wherein the fifth driving member 421 is disposed on the bracket 10 and connected to the second extrusion block 422, and the first extrusion block 412 and the second extrusion block 422 are spaced apart in the first direction. Based on this, the first extrusion block 412 may be driven to move in the first direction by the fourth driving member 411, and the second extrusion block 422 may be driven to move in the first direction by the fifth driving member 421, so that the first extrusion block 412 and the second extrusion block 422 may be respectively extruded from both sides of the to-be-folded member, so that the bent to-be-folded member is further deformed to form a final shape.

[0056] The surface of the first extrusion block 412 facing the second extrusion block 422 is the first extrusion portion, and the surface of the second extrusion block 422 facing the first extrusion block 412 is the second extrusion portion.

[0057] Continue to refer Figure 2 and Figure 4 In some embodiments, the folding device may further include a second buffer 52, which is disposed on the first extrusion block 412 and is used to contact the bracket 10 when the first extrusion block 412 moves in the first direction, thereby playing a certain buffering role; of course, when the second buffer 52 buffers to the extreme buffering position, it can also limit the first extrusion block 412 to prevent the first extrusion block 412 from moving excessively.

[0058] Correspondingly, the bracket 10 can be provided with a second blocking portion 113, and the second blocking portion 113 is located on the same side as the first supporting portion in the first direction. The second blocking portion 113 can serve as a blocking element for the second buffer component 52, so that the second buffer component 52 can perform a buffering and limiting effect when it touches the second blocking portion 113.

[0059] Exemplarily, the second buffer member 52 can be a gas spring, a hydraulic spring, etc., and of course, can also be in other forms, which are not specifically limited here. In addition, the second blocking portion 113 can be a convex structure, and of course, can also be in other structures.

[0060] Continue to refer Figure 2 and Figure 4 In some embodiments, the folding device may further include a third buffer 53, which is disposed on the second extrusion block 422 and is used to contact the bracket 10 when the second extrusion block 422 moves in the first direction, thereby playing a certain buffering role; of course, when the third buffer 53 buffers to the extreme buffering position, it can also limit the second extrusion block 422 to prevent the second extrusion block 422 from moving excessively.

[0061] Correspondingly, the bracket 10 can be provided with a third blocking portion 122, and the third blocking portion 122 is located on the same side as the second supporting portion in the first direction. The third blocking portion 122 can play a blocking role on the third buffer component 53, so that the third buffer component 53 can perform buffering and limiting functions when it touches the third blocking portion 122.

[0062] For example, the third buffer member 53 can be a gas spring, a hydraulic spring, etc., and of course, it can also be in other forms, which are not specifically limited here. In addition, the third blocking portion 122 can be a convex structure, and of course, it can also be in other structures.

[0064] Based on the above arrangement, when the foldable piece is subjected to a force and is bent and deformed, the first rolling body 13 and the second rolling body 14 can be driven to rotate respectively. Compared with the method in which the two ends of the foldable piece slide relative to the first support part and the second support part respectively, the friction resistance of the foldable piece can be greatly reduced by rolling, so that a smaller force can be applied to bend and deform the foldable piece, and the problem of wear of components caused by sliding friction between the foldable piece and the first support part and the second support part respectively can be effectively alleviated.

[0065] In some more specific embodiments, the first rolling body 13 may be disposed at the bottom of the first groove 111 , and the second rolling body 14 may be disposed at the bottom of the second groove 121 .

[0066] In some embodiments, the folding device may further include a translation mechanism (not shown in the figure), which is connected to the bracket 10 to drive the bracket 10 to translate. The translation direction may be a first direction or other directions.

[0067] Optionally, the translation mechanism may include a linear module, which may be a cylinder, a hydraulic cylinder, an electric cylinder, a screw slider, etc. Exemplarily, the linear module may be a rodless cylinder.

[0068] like Figure 5 As shown, the process of using the folding device to bend the folded piece in the embodiment of the present application is as follows:

[0069] Place the piece to be folded on the bracket 10, and support one end of the piece to be folded by the first support part, and support the other end of the piece to be folded by the second support part; wherein a robot arm may be used to transfer the piece to be folded;

[0070] The positioning mechanism 30 is started, and the first positioning member 32 and the second positioning member 33 are driven to be relatively close to each other through the third driving member 31, so as to position the folded member to ensure the position accuracy of the folded member;

[0071] The first driving assembly 21 is started, and the force applying assembly 22 is driven by the first driving member 211 to move toward the to-be-folded member in the second direction, and the first clamping member 222 and the second clamping member 223 of the force applying assembly 22 are respectively located on both sides of the to-be-folded member;

[0072] The force applying component 22 is started, and the first clamping member 222 and the second clamping member 223 are driven to approach each other in the third direction through the second driving member 221, and the area between the two ends of the to-be-folded member is clamped from both sides;

[0073] The first driving component 21 is started again, and the force applying component 22 and the area between the two ends of the clamped piece to be folded are driven to move in the second direction through the first driving member 211, so that the piece to be folded is bent and deformed;

[0074] The forming mechanism 40 is started, the fourth driving member 411 drives the first extruding block 412 to extrude the bent and deformed part to be folded on one side in the first direction, and the fifth driving member 421 drives the second pressing block to extrude the bent and deformed part to be folded on the other side in the first direction, so that the part to be folded is further bent and deformed, so that the part to be folded forms the final shape. At this point, the folding operation of the part to be folded is completed.

[0076] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
