[0042] 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.

[0043] Reference below Figures 1 to 7 A bending device according to an embodiment of the first aspect of the present invention is described in detail.

[0044] refer to Figures 1 to 3 According to a first embodiment of the present invention, a bending device comprises a positioning fixture 100, a driving module 200, a first bending module 300 and a second bending module 400. The positioning fixture 100 is provided with a positioning groove 110, and the positioning groove 110 is used to position the workpiece. The positioning fixture 100 is provided with a through hole 120 connected to the positioning groove 110; the driving module 200 is connected to the positioning fixture 100, and is used to drive the positioning fixture 100 to pass through the first bending position and the second bending position in sequence; the first bending The bending die set 300 is used to perform a first bend on the workpiece on the positioning fixture 100 located at the first bending position to form a first crease on the workpiece; the second bending die set 400 includes a second lifting mechanism 410 and a second bending mechanism 420. The second lifting mechanism 410 can penetrate the through hole 120 of the positioning fixture 100 located at the second bending position and lift the workpiece in the positioning groove 110. The second bending mechanism 420 is used to perform a second bend on the lifted workpiece to form a second crease on the workpiece.

[0045] During the operation of the bending device of the present application, the workpiece is first placed in the positioning groove 110 of the positioning jig 100 to position the workpiece, and then the positioning jig 100 is driven to move to the first bending position by the driving module 200, and the portion of the workpiece on the positioning jig 100 protruding from the positioning groove 110 is bent by the first bending module 300 to form a first crease on the workpiece, and then the positioning jig 100 is moved to the second bending position by the driving module 200. At this time, the second lifting mechanism 410 in the second bending module 400 is opposite to the through hole 120 in the positioning jig 100, the second lifting mechanism 410 passes through the through hole 120 upward, and lifts the workpiece in the positioning groove 110 upward for a distance, and then the portion of the workpiece protruding from the positioning groove 110 is bent by the second bending mechanism 420 to form a second crease. It can be seen from the above working process that the present application can form a first crease on the workpiece through the first bending module 300, and then lift the bent workpiece upward through the second lifting mechanism 410, so that the second bending module 400 can form a second crease on the workpiece, thereby realizing automatic two-stage bending of the workpiece, further improving production efficiency.

[0046] In a specific embodiment of the present invention, the first bending module 300 includes a first driving structure and a first bending member. The first bending member is provided with a first arc surface on one side close to the positioning fixture 100. The first arc surface is used to abut against the workpiece. The first driving structure is used to drive the first bending member downward to approach the workpiece located at the first bending position, so that the first arc surface pushes the workpiece to bend in the horizontal direction and forms a first fold on the workpiece. It can be understood that by setting the first arc surface, the horizontal bending of the workpiece can be completed in the process of the first driving structure driving the first bending member to move in the vertical direction, which reduces the space required for the first bending module 300 in the horizontal direction, making the overall structure of the bending device more compact. In addition, it should be noted that the workpiece is thin, and the workpiece is inserted into the positioning groove 110 in the vertical direction. The first bending member moves in the height direction and bends the workpiece through the first arc surface, which can reduce the risk of the workpiece being taken out of the positioning groove 110 during the bending process. For example, if the part of the workpiece protruding from the positioning groove 110 is pushed in the horizontal direction for bending, the workpiece may be taken away from the positioning groove 110.

[0047] like Figure 1 , Figure 3 and Figure 7As shown, in a specific embodiment of the present invention, the second lifting mechanism 410 includes a lifting block 411 and a lifting driver 412. The lifting driver 412 can drive the lifting block 411 to penetrate the through hole 120 of the positioning fixture 100 in the vertical direction, and lift the workpiece in the positioning groove 110 connected to the through hole 120 upward for a distance. After the workpiece is bent by the second bending mechanism 420, the lifting driver 412 can drive the lifting block 411 to disengage from the through hole 120 of the positioning fixture 100 in the vertical direction.

[0048] refer to Figure 1 and Figure 4 In some embodiments of the present invention, the bending device further includes a first loading module 500, a transfer module 600, and a second loading module 700. The first loading module 500 includes a vibration plate 510 and a manipulator 520. The transfer module 600 includes a positioning mechanism 610. The manipulator 520 is used to transfer the workpiece in the vibration plate 510 to the positioning mechanism 610 of the transfer module 600. The second loading module 700 is used to move the workpiece on the positioning mechanism 610 to the positioning groove 110. It can be understood that the workpiece is first placed in the vibration plate 510, and then the workpiece is moved from the vibration plate 510 to the transfer module 600 by the manipulator 520, and the workpiece is positioned by the positioning mechanism 610 in the transfer module 600, and then the workpiece on the positioning mechanism 610 is transferred to the positioning groove 110 of the positioning fixture 100 by the second loading module 700, so as to realize automatic loading of the workpiece.

[0049] In a further embodiment of the present invention, the bending device also includes a CCD detection module, which is arranged on the upper side of the vibration plate 510 and is used to detect the position of the workpiece in the vibration plate 510. The manipulator 520 is electrically connected to the CCD detection module and can accurately absorb the workpiece according to the detection structure of the CCD detection module.

[0050] like Figure 1 and Figure 6 As shown, in a specific embodiment of the present invention, the driving module 200 can drive the positioning fixture 100 to pass through the loading position and the first bending position in sequence. The second loading module 700 is arranged on one side of the loading position, and includes a clamping mechanism 710, a horizontal driving mechanism 720 and a vertical driving mechanism 730. The horizontal driving mechanism 720 is used to drive the clamping mechanism 710 to move between the material taking position and the loading position in a horizontal direction, and the vertical driving mechanism 730 is used to drive the clamping mechanism 710 to move in a vertical direction to approach or move away from the positioning mechanism 610 or the positioning fixture 100.

[0051] It should be noted that after the second loading module 700 transports the workpiece to the positioning groove 110 of the positioning fixture 100 located at the loading position, the workpiece may tilt when falling into the bottom of the positioning groove 110, causing the workpiece to be stuck in the middle of the positioning groove 110.

[0052] In order to avoid workpiece jamming, in some embodiments of the present invention, the bending device further includes a first lifting mechanism, which can penetrate the through hole 120 of the positioning fixture 100 located at the loading position and extend into the positioning groove 110 of the positioning fixture 100. The specific structure of the first lifting mechanism refers to the specific structure of the second lifting mechanism 410. It can be understood that by setting the first lifting mechanism, the first lifting mechanism can lift the workpiece to correct the posture of the workpiece so that the workpiece can smoothly fall into the bottom of the groove.

[0053] refer to Figure 4 In some embodiments, the transfer module 600 also includes a horizontal transfer mechanism 620, which is connected to the positioning mechanism 610 and is used to drive the positioning mechanism 610 to reciprocate between the temporary storage position and the material picking position. The manipulator 520 is used to transfer the workpiece in the vibration plate 510 to the positioning mechanism 610 located at the temporary storage position, and the second loading module 700 is used to move the workpiece on the positioning mechanism 610 located at the material picking position to the positioning groove 110.

[0054] It can be understood that in the bending device of the present application, the workpiece in the vibration plate 510 is transferred to the positioning mechanism 610 located at the temporary storage position by the manipulator 520, and then the positioning mechanism 610 is driven to move from the temporary storage position to the material fetching position by the horizontal transfer mechanism 620, and then the workpiece in the positioning mechanism 610 is moved to the positioning groove 110 of the positioning fixture 100 by the second loading module 700 to realize automatic loading of the workpiece. From the above, it can be known that the present application can reduce the possibility of interference between the second loading module 700 and the manipulator 520 during the working process by placing the workpiece in the positioning mechanism 610 at the temporary storage position and the second loading module 700 at the material fetching position.

[0055] Specifically, the horizontal transfer mechanism 620 includes a horizontal transfer rail, a horizontal transfer slide and a horizontal transfer driver. The horizontal transfer rail extends along a first direction. The horizontal transfer driver is used to drive the horizontal transfer slide to move along the horizontal transfer rail. The positioning mechanism 610 is arranged on the horizontal transfer slide.

[0056] It should be noted that the workpiece is in a horizontal position when in the vibration plate 510 , and is in a vertical position when in the positioning groove 110 in the positioning fixture 100 , so as to facilitate bending of the workpiece.

[0057] like Figure 4As shown, in some embodiments, the transfer module 600 also includes an angle adjustment mechanism 630, which is connected to the positioning mechanism 610 and is used to drive the positioning mechanism 610 to rotate around the horizontal axis so that the workpiece on the positioning mechanism 610 switches from a horizontal posture to a vertical posture. It can be understood that when the manipulator 520 moves the workpiece from the vibration plate 510 to the positioning mechanism 610, the workpiece is in a horizontal posture, and the positioning mechanism 610 is driven to rotate around the horizontal axis by the angle adjustment mechanism 630 so that the workpiece switches from a horizontal posture to a vertical posture. At this time, the second loading module 700 can move the workpiece in a vertical posture to the positioning groove 110 of the positioning fixture 100 to facilitate bending the workpiece.

[0058] Specifically, the angle adjustment mechanism 630 includes an angle adjustment motor and a transmission belt. The angle adjustment motor can drive the supporting seat 611 to rotate around the horizontal axis through the transmission belt.

[0059] like Figure 4 and Figure 5 As shown, in some embodiments, the positioning mechanism 610 includes a supporting seat 611 and a clamping structure 612, the supporting seat 611 is provided with a first limiting surface 611a, the clamping structure 612 includes a clamping block 612a and a first driver, the clamping block 612a and the first limiting surface 611a are distributed along a first direction, the first driver can drive the clamping block 612a to approach or move away from the first limiting surface 611a to clamp or release the workpiece, and a clamping area is formed between the first limiting surface 611a and the clamping block 612a. It can be understood that the workpiece in the vibration plate 510 is moved to the clamping area formed by the first limiting surface 611a and the clamping block 612a by the manipulator 520, and then the clamping block 612a is driven by the first driver to approach the first limiting surface 611a along the first direction to cooperate with the first limiting surface 611a to clamp the workpiece, and then the positioning mechanism 610 is driven to rotate around the horizontal axis by the angle adjustment mechanism 630. At this time, the workpiece can rotate around the horizontal axis, thereby realizing the switching of the spatial posture of the workpiece; the clamping block 612a is driven by the first driver to move away from the first limiting surface 611a along the first direction to release the workpiece, and at this time the second loading module 700 can smoothly drive the workpiece to separate from the supporting seat 611.

[0060] like Figure 4 and Figure 5As shown, in one embodiment, a second limiting surface 611b is provided on the bearing seat 611, and the second limiting surface 611b is distributed on one side of the clamping area in the second direction. The positioning mechanism 610 also includes a limiting structure 613, and the limiting structure 613 includes a limiting block 613a and a second driver 613b. The second driver 613b can drive the limiting block 613a to move to the other side of the clamping area in the second direction, so as to cooperate with the second limiting surface 611b to limit the workpiece in the clamping area in the second direction. It can be understood that when the workpiece is placed in the clamping area by the manipulator 520, the workpiece is carried on the second limiting surface 611b, and the second driver 613b can drive the limiting block 613a to move to the side of the workpiece away from the second limiting surface 611b, thereby realizing the limitation of the movement of the workpiece in the second direction, so as to reduce the possibility of the workpiece escaping from the clamping area.

[0061] Specifically, the first direction is a horizontal direction, and the second direction is a vertical direction.

[0062] In a further embodiment of the present invention, a plurality of placement positions are provided on the bearing seat 611, each placement position is defined by a first limiting surface 611a and a second limiting surface 611b, the clamping structure 612 includes a plurality of clamping blocks 612a, the clamping blocks 612a are arranged one by one with the placement positions, and the first driver can drive the plurality of clamping blocks 612a to approach or move away from the first limiting surface 611a of the corresponding placement position at the same time, so as to clamp the workpiece at each placement position; the limiting structure 613 includes a plurality of limiting blocks 613a, each placement position is at least provided with a limiting block 613a, and the second driver 613b can simultaneously drive the plurality of limiting blocks 613a to move to the side of the clamping area away from the second limiting surface 611b. It can be understood that by providing a plurality of placement positions on the bearing seat 611, and limiting the workpieces by the clamping structure 612 and the limiting structure 613 at the same time, so as to adjust the spatial posture of the plurality of workpieces, the loading efficiency of the workpieces can be further improved, thereby improving the production efficiency of the bending device.

[0063] In some embodiments of the present invention, the clamping mechanism 710 of the second loading module 700 includes a plurality of pneumatic clamps, which are arranged in a one-to-one correspondence with the placement positions, and the positioning fixture 100 is provided with a plurality of corresponding positioning grooves 110 and a plurality of through holes 120, and the positioning grooves 110 are arranged in a one-to-one correspondence with the pneumatic clamps. The second lifting mechanism 410 is provided with a plurality of lifting blocks 411, and the lifting blocks 411 are arranged in a one-to-one correspondence with the through holes 120, and each lifting block 411 is connected to the output end of the lifting driver 412.

[0064] refer to Figure 1In a further embodiment of the present invention, the bending device further includes two transfer modules 600 distributed along the second direction. It is understandable that when the placement positions on one of the transfer modules 600 are all placed with workpieces by the manipulator 520, the horizontal transfer mechanism 620 drives the transfer module 600 to move to the material taking position, waiting for the second loading module 700 to move the workpiece on the transfer module 600 to the positioning fixture 100. At this time, the manipulator 520 can continue to place the workpiece on the placement position of another transfer module 600 located in the temporary storage position until the placement positions of the transfer module 600 are all loaded with workpieces. It is understandable that by setting two transfer modules 600, the working efficiency of the manipulator 520 can be improved, thereby improving the production efficiency of the bending device.

[0065] refer to Figure 1 and Figure 2 In some embodiments of the present invention, the driving module 200 includes a rotating motor 210 and a turntable 220. The rotating motor 210 is used to drive the turntable 220 to rotate around its own axis. The positioning fixture 100 is arranged on the turntable 220. The rotating motor 210 can drive the positioning fixture 100 on the turntable 220 to pass through the first bending position and the second bending position in sequence. It can be understood that when the workpiece is placed in the positioning groove 110 of the positioning fixture 100, the turntable 220 is driven to rotate by the rotating motor 210, thereby driving the positioning fixture 100 on the turntable 220 to rotate, so that the positioning fixture 100 is rotated to the first bending position, and then the workpiece is bent for the first time by the first bending module 300, and then the rotating motor 210 continues to drive the turntable 220 to rotate, so that the positioning fixture 100 is rotated to the second bending position, and then the workpiece in the positioning groove 110 is lifted upward for a distance by the second lifting mechanism 410 of the second bending module 400, and then the workpiece is bent for the second time by the second bending mechanism 420 to complete the automatic two-stage bending of the workpiece.

[0066] It can be understood that the rotating motor 210 drives the turntable 220 to rotate to achieve the movement of the positioning fixture 100, so that the first bending module 300 and the second bending module 400 can be arranged around the turntable 220, thereby making the overall structure of the bending device more compact.

[0067] In a further embodiment of the present invention, a plurality of positioning jigs 100 are disposed on the turntable 220 at intervals in the circumferential direction around the rotation axis of the turntable 220 .

[0068] refer to Figure 1In some embodiments of the present invention, the bending device further includes a blanking module 800, and the driving module 200 can drive the positioning fixture 100 to pass through the second bending position and the blanking position in sequence, and the blanking module 800 is used to blank the workpiece on the positioning fixture 100 located at the blanking position. It can be understood that after the second bending mechanism 420 bends the workpiece for the second time, the second lifting mechanism 410 disengages from the through hole 120, and the driving module 200 drives the positioning fixture 100 to move to the blanking position, and the blanking module 800 can blank the workpiece that has been bent twice. The specific structure of the blanking module 800 is similar to the specific structure of the second loading module 700, and the specific structure of the blanking module 800 refers to the second loading module 700.

[0069] refer to Figure 1 , Figure 3 and Figure 7 In some embodiments of the present invention, the second bending mechanism 420 includes a second driving structure 421 and a second bending member 422. The second bending member 422 is provided with a second arc surface 422a on the side close to the positioning fixture 100. The second arc surface 422a is used to abut against the workpiece. The second driving structure 421 is used to drive the second bending member 422 downward to approach the workpiece located at the second bending position, so that the second arc surface 422a pushes the workpiece to bend in the horizontal direction and forms a second fold on the workpiece. It can be understood that by providing the second arc surface 422a, the horizontal bending of the workpiece can be completed in the process of the second driving structure 421 driving the second bending member 422 to move in the vertical direction, thereby reducing the space required for the second bending mechanism 420 in the horizontal direction, and making the overall structure of the bending device more compact.

[0070] Specifically, the second driving structure 421 includes a crank slider structure and a bending motor, and the output end of the bending motor is transmission-connected to the second bending member 422 via the crank slider assembly.

[0071] The working method of a bending device according to the second aspect of the present invention is described in detail below.

[0072] The working method of the bending device according to the second aspect of the present invention comprises the following steps:
