[0039] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0040] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0041] Reference below Figures 1 to 6 A bending device according to an embodiment of the first aspect of the present invention is described in detail.

[0042] refer to Figures 1 to 3 A bending device according to an embodiment of the present invention includes a first bending module 100, a conveying module 200 and a second bending module 300. The first bending module 100 includes a first bending mechanism 110 and a first loading platform 120. The first bending mechanism 110 is used to bend the workpiece on the first loading platform 120 to form a preset crease; the conveying module 200 is arranged on one side of the first bending module 100; the second bending module 300 is arranged on one side of the first bending module 100, and includes a second bending mechanism 310 and a second loading platform 320. The conveying module 200 is used to move the bent workpiece on the first loading platform 120 to the second loading platform 320, and the second bending mechanism 310 is used to repeatedly bend the workpiece on the second loading platform 320 along the preset crease.

[0043] During the operation of the bending device of the present embodiment, the workpiece is first placed on the first carrier 120 in the first bending module 100, and then the workpiece on the first carrier 120 is bent by the first bending mechanism 110 to form a preset crease on the workpiece, and then the bent workpiece is moved from the first carrier 120 to the second carrier 320 of the second bending module 300 by the transport module 200, and then the workpiece on the second carrier 320 is repeatedly bent along the preset crease by the second bending mechanism 310. It can be seen from the above operation process that the bending device of the present application can realize automatic bending of the workpiece through the first bending module 100, and then repeatedly bend the workpiece through the second bending module 300 to test the toughness of the workpiece, thereby completing the automatic bending and bending test of the workpiece, reducing manual intervention, and avoiding the problems of inadequate bending and missed folding caused by manual bending.

[0044] refer to Figure 2 and Figure 4 In some embodiments of the present invention, the second bending mechanism 310 includes a motor 311, an eccentric transmission structure 312 and a clamping structure 313. The output end of the motor 311 is connected to the clamping structure 313 through the eccentric transmission structure 312. The clamping structure 313 is used to clamp one end of the workpiece. The motor 311 can drive the clamping structure 313 to swing back and forth around the swing axis through the eccentric transmission structure 312. When the clamping structure 313 clamps the workpiece, the swing axis is collinear with the preset fold on the workpiece. It can be understood that the clamping structure 313 can clamp the workpiece on the second carrier 320. When the clamping structure 313 clamps the workpiece and the swing axis of the clamping structure 313 is collinear with the preset fold on the workpiece, the eccentric transmission structure 312 is driven to rotate by the motor 311, so that the clamping structure 313 swings back and forth around the swing axis, so that the workpiece clamped by the clamping structure 313 can swing back and forth around the swing axis, and the workpiece can be repeatedly bent along the preset fold.

[0045] Specifically, the eccentric transmission structure 312 is a turntable, the clamping structure 313 is a pneumatic clamp, the motor 311 is used to drive the turntable to rotate forward and reverse around the rotation axis, the clamping structure 313 is eccentrically arranged relative to the turntable, and the swing axis of the clamping structure 313 is colinear with the rotation axis.

[0046] like Figure 2 and Figure 4As shown, in one embodiment, the second bending module 300 further includes a first position adjustment mechanism 330, the first position adjustment mechanism 330 is drivingly connected to the second bending mechanism 310, the clamping structure 313 has a clamping area for clamping the workpiece, and the first position adjustment mechanism 330 can drive the clamping structure 313 to move so that the workpiece portion on the second carrier 320 is located in the clamping area. It can be understood that since the first position adjustment mechanism 330 is drivingly connected to the second bending mechanism 310, the second bending mechanism 310 is driven to move by the first position adjustment mechanism 330, so that the swing axis of the clamping structure 313 is collinear with the preset fold of the workpiece, and the workpiece portion on the second carrier 320 is located in the clamping area of ​​the clamping structure 313. It can be understood that the first position adjustment mechanism 330 can drive the clamping structure 313 to move to avoid the workpiece, so that the workpiece can be smoothly placed on the second carrier 320 or detached from the second carrier 320.

[0047] In a specific embodiment of the present invention, the first position adjustment mechanism 330 includes a first horizontal adjustment structure 331, a second horizontal adjustment structure 332 and a vertical adjustment structure 333. The vertical adjustment structure 333 is connected to the clamping structure 313 and can drive the clamping structure 313 to move in the vertical direction; the first horizontal adjustment structure 331 is connected to the vertical adjustment structure 333 and can drive the vertical adjustment structure 333 to move in the first horizontal direction to drive the clamping structure 313 to move in the first horizontal direction; the second horizontal adjustment structure 332 is connected to the first horizontal adjustment structure 331 and can drive the first horizontal adjustment structure 331 to move in the second horizontal direction to drive the clamping structure 313 to move in the second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction.

[0048] In a further embodiment of the present invention, the second bending module 300 includes two second bending mechanisms 310 and two first position adjustment mechanisms 330. One second bending mechanism 310 is connected to one first position adjustment mechanism 330, and they perform repeated bending on different positions of the same workpiece.

[0049] It should be understood that the specific number of the second bending mechanism 310 and the first position adjustment mechanism 330 can be adjusted according to the actual number of bending positions, and is not limited to two in the above embodiment.

[0050] refer to Figure 3 and Figure 5In some embodiments of the present invention, the first bending mechanism 110 includes a pressing structure 111 and a bending structure 112. The bending structure 112 is arranged at the lower side of the pressing structure 111. The pressing structure 111 is used to press and fix the workpiece on the first carrier 120. The first carrier 120 is provided with an avoidance through hole 120a. The bending structure 112 can pass through the avoidance through hole 120a to push the workpiece upward and complete the bending of the workpiece. It can be understood that after the workpiece is placed on the first carrier 120, and the preset bending position of the workpiece is aligned with the avoidance through hole 120a, the workpiece is pressed and fixed on the first carrier 120 by the pressing structure 111, and then the bending structure 112 passes through the avoidance through hole 120a and lifts the workpiece, so that the workpiece is bent at the preset bending position. Finally, the bending structure 112 is reset and the pressing structure 111 is released.

[0051] It can be understood that after the bending structure 112 passes through the avoidance hole 120a, the bending structure 112 can push the workpiece to bend toward the downward pressing structure 111, and the bending structure 112 is close to the downward pressing structure 111, so that the bending angle of the workpiece is larger, and the part of the workpiece located between the bending structure 112 and the downward pressing structure 111 forms a preset crease.

[0052] In a specific embodiment of the present invention, the pressing structure 111 includes a pressing cylinder 111a and a pressing block 111b. The pressing cylinder 111a is used to drive the pressing block 111b to move downward in a vertical direction so that the pressing block 111b can abut against the workpiece on the first supporting platform 120. The bending structure 112 includes a bending cylinder 112a and a top block 112b. The bending cylinder 112a is used to drive the top block 112b to move upward in a vertical direction so that the top block 112b can pass through the avoidance hole 120a and bend the workpiece upward.

[0053] In a further embodiment of the present invention, the first bending module 100 also includes a second position adjustment mechanism 130, which is connected to the first bending mechanism 110 and is used to drive the first bending mechanism 110 to move so that the workpiece is located between the pressing structure 111 and the bending structure 112, and the top block 112b can be aligned with the preset bending position of the workpiece.

[0054] It is understandable that the second position adjustment mechanism 130 can drive the first bending mechanism 110 to move to avoid the workpiece, so that the workpiece can be smoothly placed on the first loading platform 120 or detached from the first loading platform 120.

[0055] Specifically, the second position adjustment mechanism 130 can drive the first bending mechanism 110 to move along the second horizontal direction to adjust the position of the first bending mechanism 110 in the second horizontal direction.

[0056] In a further embodiment of the present invention, the first bending module 100 includes two first bending mechanisms 110 and two second position adjustment mechanisms 130. One first bending mechanism 110 is respectively connected to one second position adjustment mechanism 130, and respectively bends different positions of the same workpiece.

[0057] It should be understood that the specific number of the first bending mechanism 110 and the second position adjustment mechanism 130 can be adjusted according to the actual number of bending positions, and is not limited to two in the above embodiment.

[0058] like Figure 3 and Figure 5 As shown, in some embodiments, the first carrier platform 120 includes a mounting frame 121, a driving structure 122, a first carrier plate 123 and a second carrier plate 124, the first carrier plate 123 and the second carrier plate 124 are both used to carry workpieces, the mounting frame 121 is provided with a temporary storage position and a bending position, the driving structure 122 is respectively connected to the first carrier plate 123 and the second carrier plate 124, and is used to drive the first carrier plate 123 and the second carrier plate 124 to move between the temporary storage position and the bending position, the first bending mechanism 110 is arranged on one side of the bending position, and is used to bend the workpiece on the bending position, and the transport module 200 can transport the workpiece on the temporary storage position to the second carrier platform 320.

[0059] It can be understood that when the first carrier plate 123 is located in the bending position, the workpiece is placed on the first carrier plate 123, and the first bending mechanism 110 bends the workpiece located on the first carrier plate 123 to form a preset crease, and then the first carrier plate 123 is driven to move to the temporary storage position through the driving structure 122, and the second carrier plate 124 located in the temporary storage position is moved to the bending position. At this time, the conveying module 200 can convey the bent workpiece in the temporary storage position to the second carrier platform 320. At the same time, the first bending mechanism 110 can bend the workpiece on the second carrier plate 124 located in the bending position, thereby improving the bending efficiency of the first bending module 100.

[0060] Specifically, the driving structure 122 is a conveyor belt.

[0061] refer to Figure 3 and Figure 5 In some embodiments of the present invention, the temporary storage position and the bending position are distributed along a preset horizontal direction, the first supporting plate 123 is slidably arranged on the mounting frame 121 along the preset horizontal direction, the first supporting platform 120 also includes a lifting structure 125, the lifting structure 125 is slidably arranged on the mounting frame 121 along the preset horizontal direction, the second supporting plate 124 is connected to the lifting structure 125, and the lifting structure 125 can drive the second supporting plate 124 to perform lifting movement so that the second supporting plate 124 can avoid the first supporting plate 123 in the vertical direction.

[0062] It can be understood that when the first carrier plate 123 and the second carrier plate 124 approach each other along a preset horizontal direction under the drive of the driving structure 122, the second carrier plate 124 can be lifted and lowered in the vertical direction through the lifting structure 125, so that the second carrier plate 124 and the first carrier plate 123 are in different horizontal planes, so that when the first carrier plate 123 moves from the temporary storage position to the bending position, the second carrier plate 124 can smoothly move from the bending position to the temporary storage position.

[0063] like Figure 3 and Figure 5 As shown, in one embodiment, the mounting frame 121 is provided with a slide groove 126 extending along a preset horizontal direction, the slide groove 126 includes a first section 126a, a second section 126b and a third section 126c which are connected in sequence, the horizontal height of the second section 126b is lower than the horizontal height of the first section 126a and the horizontal height of the third section 126c, the lifting structure 125 includes a slide seat 125a and a slide rail 125b, the slide rail 125b extends in the vertical direction and is slidably arranged on the mounting frame 121 along the preset horizontal direction, the slide seat 125a is slidably arranged on the slide rail 125b in the vertical direction, and is connected to the second bearing plate 124, the slide seat 125a is provided with a guide portion 125c, and the guide portion 125c is penetrated into the slide groove 126.

[0064] It can be understood that when the slide rail 125b slides on the mounting frame 121 along the preset horizontal direction, the guide portion 125c of the slide seat 125a slides in the slide groove 126. When the guide portion 125c is located in the first section 126a of the slide groove 126, the second supporting plate 124 and the first supporting plate 123 are distributed along the preset horizontal direction. When the guide portion 125c slides to the second section 126b of the slide groove 126, the slide seat 125a moves downward in the vertical direction under the action of gravity, and the second supporting plate 124 drops accordingly to avoid the first supporting plate 123. Then the second supporting plate 124 continues to move under the action of the driving structure 122, so that the guide portion 125c slides toward the third section 126c of the slide groove 126, and the guide portion 125c of the slide seat 125a moves upward under the support of the groove wall of the slide groove 126, and the second supporting plate 124 rises accordingly.

[0065] Specifically, the first section 126a and the third section 126c are respectively arranged at the bending position and the temporary storage position of the mounting frame 121, and the first section 126a and the third section 126c have the same horizontal height. When the guide portion 125c is located in the first section 126a, the horizontal height of the second supporting plate 124 is the same as the horizontal height of the first supporting plate 123.

[0066] refer to Figure 2In some embodiments of the present invention, the second bending module 300 further includes a pressing mechanism 340, which includes a driver 341 and a pressing block 342. The driver 341 is connected to the pressing block 342 and is used to drive the pressing block 342 to approach or move away from the second carrier 320 to press or release the workpiece on the second carrier 320. It can be understood that when the bent workpiece moves to the second carrier 320, the driver 341 drives the pressing block 342 to approach the second carrier 320 and press the workpiece on the second carrier 320, and then the second bending mechanism 310 repeatedly bends the workpiece along the preset fold. Pressing the workpiece on the second carrier 320 by the pressing block 342 can reduce the possibility of the position of the workpiece being offset during repeated bending, thereby affecting the bending effect of the workpiece.

[0067] like Figure 2 As shown, in one embodiment, the driver 341 includes a rotary downward pressure cylinder. It is understandable that, by connecting the output end of the rotary downward pressure cylinder with the pressing block 342, when the workpiece is placed on the second carrier 320, the rotary downward pressure cylinder can drive the pressing block 342 to rotate forward and move downward toward the workpiece until the workpiece is pressed tightly against the second carrier 320. After the repeated bending of the workpiece is completed, the rotary downward pressure cylinder can drive the pressing block 342 to rotate upward and in the opposite direction away from the workpiece. At this time, the workpiece can be smoothly detached from the second carrier 320. By providing the rotary downward pressure cylinder, the workpiece does not need to avoid the pressing block 342 when being transported to or detached from the second carrier 320.

[0068] refer to Figure 6 In some embodiments of the present invention, the transport module 200 includes an adsorption mechanism 210, a horizontal drive mechanism 220, a vertical drive mechanism 230 and a rotation adjustment mechanism 240. The adsorption mechanism 210 is used to adsorb the workpiece. The horizontal drive mechanism 220 is connected to the vertical drive mechanism 230. The vertical drive mechanism 230 is connected to the rotation adjustment mechanism 240. The rotation adjustment mechanism 240 is connected to the adsorption mechanism 210. The horizontal drive mechanism 220 is used to drive the adsorption mechanism 210 to move horizontally between the first carrier platform 120 and the second carrier platform 320. The vertical drive mechanism 230 is used to drive the adsorption mechanism 210 to approach or move away from the first carrier platform 120 or the second carrier platform 320 in the vertical direction. The rotation adjustment mechanism 240 is used to adjust the horizontal posture of the adsorption mechanism 210 so that the workpiece can be aligned with the second carrier platform 320.

[0069] In some embodiments of the present invention, the die-cutting system also includes a silo 400, a conveyor line 500, a loading module 600 and a unloading module 700. The loading module 600 is used to move the workpiece from the silo 400 to the first supporting platform 120, and the unloading module 700 is used to move the workpiece after repeated bending on the second supporting platform 320 to the conveyor line 500. The specific structure of the loading module 600 and the unloading module 700 refers to the specific structure of the transport module 200.

[0070] In a further embodiment of the present invention, the bending device includes two second bending modules 300. By providing two second bending modules 300, the bending efficiency of repeated bending is improved, thereby improving the production efficiency of the entire bending device.

[0071] In some embodiments of the present invention, the first carrier 120 can fully support the edge of the workpiece, and the second carrier 320 can only support part of the edge of the workpiece. It can be understood that, since the preset bending position of the workpiece is located in the middle area of ​​the workpiece, the first carrier 120 is provided with an avoidance through hole 120a so that the bending structure 112 can bend the preset bending position of the workpiece, and the edge of the workpiece can be supported by the workpiece; when the workpiece is bent, the bending area of ​​the workpiece is tilted upward, and only part of the support structure is provided on the second carrier 320 to support the bending area of ​​the workpiece, which not only facilitates the clamping structure 313 to clamp the workpiece, but also, since the bending area of ​​the workpiece is only partially supported by the second carrier 320, the bending area of ​​the workpiece is more horizontal under the action of force.

[0072] The working method of a bending device according to the second aspect of the present invention is described in detail below.

[0073] A working method of a bending device according to an embodiment of the second aspect of the present invention comprises the following steps:

[0074] Placing the workpiece on the first loading platform 120;

[0075] Bending the workpiece on the first carrying platform 120 to form a preset crease;

[0076] The bent workpiece is transported from the first loading platform 120 to the second loading platform 320;
