Description

Technical Field

[0002] The headphone case's magnetic sensors are made of a soft material. During assembly, the magnetic sensors on both sides need to be bent to accommodate the product. After bending, the magnetic sensors need to be repeatedly bent to remove those with poor toughness. In related technologies, the magnetic sensors need to be bent manually by workers, and their toughness needs to be tested. Consequently, because the magnetic sensors require manual bending, there is a risk of incomplete bending and missed bends, leading to defects. Utility Model Content

[0032] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, left, right, front, and back, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] The following is for reference. Figures 1 to 6 A bending device according to an embodiment of the present utility model will be described in detail.

[0036] refer to Figures 1 to 3 A bending device according to an embodiment of the present invention includes a first bending module 100, a transport module 200, and a second bending module 300. The first bending module 100 includes a first bending mechanism 110 and a first support platform 120. The first bending mechanism 110 is used to bend a workpiece on the first support platform 120 to form a preset crease. The transport module 200 is disposed on one side of the first bending module 100. The second bending module 300 is disposed on one side of the first bending module 100 and includes a second bending mechanism 310 and a second support platform 320. The transport module 200 is used to move the bent workpiece on the first support platform 120 to the second support platform 320. The second bending mechanism 310 is used to repeatedly bend the workpiece on the second support platform 320 along the preset crease.

[0037] In the operation of the bending device in this embodiment, the workpiece is first placed on the first support platform 120 in the first bending module 100. Then, the first bending mechanism 110 bends the workpiece on the first support platform 120 to form a preset crease. Next, the conveying module 200 moves the bent workpiece from the first support platform 120 to the second support platform 320 of the second bending module 300. Then, the second bending mechanism 310 repeatedly bends the workpiece on the second support platform 320 along the preset crease. From the above operation, it can be seen that the bending device of this application can automatically bend the workpiece through the first bending module 100, and then repeatedly bend the workpiece through the second bending module 300 to test the workpiece's toughness, thereby completing the automatic bending and bending test of the workpiece, reducing manual intervention and avoiding problems such as incomplete bending and missed bends caused by manual bending.

[0038] refer to Figure 2 and Figure 4In some embodiments of this utility model, 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 driven to connect 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 crease on the workpiece. It can be understood that the clamping structure 313 can clamp the workpiece on the second support platform 320. When the clamping structure 313 clamps the workpiece, and the swing axis of the clamping structure 313 is collinear with the preset crease on the workpiece, the eccentric transmission structure 312 is driven to rotate by the motor 311, thereby causing the clamping structure 313 to swing 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 bend repeatedly along the preset crease.

[0039] Specifically, the eccentric transmission structure 312 is a turntable, the clamping structure 313 is a pneumatic gripper, the motor 311 is used to drive the turntable to rotate forward and backward around the rotation axis, the clamping structure 313 is eccentrically set relative to the turntable, and the swing axis of the clamping structure 313 is collinear with the rotation axis.

[0040] like Figure 2 and Figure 4 As shown, in one embodiment, the second bending module 300 further includes a first position adjustment mechanism 330, which is drivenly connected to the second bending mechanism 310. The clamping structure 313 has a clamping area for clamping a workpiece. The first position adjustment mechanism 330 can drive the clamping structure 313 to move, so that a portion of the workpiece on the second support platform 320 is located within the clamping area. It is understood that, since the first position adjustment mechanism 330 is drivenly connected to the second bending mechanism 310, by driving the second bending mechanism 310 to move, the swing axis of the clamping structure 313 is collinear with the preset crease of the workpiece, and the portion of the workpiece on the second support platform 320 is located within the clamping area of ​​the clamping structure 313. It is understood that the first position adjustment mechanism 330 can drive the clamping structure 313 to move to avoid the workpiece, allowing the workpiece to be smoothly placed on or removed from the second support platform 320.

[0041] In a specific embodiment of this utility model, 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, thereby driving 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, thereby driving the clamping structure 313 to move in the second horizontal direction. The first horizontal direction and the second horizontal direction are perpendicular to each other.

[0042] 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 repeatedly bend the same workpiece at different positions.

[0043] 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 required, and is not limited to the two in the above embodiment.

[0044] refer to Figure 3 and Figure 5 In some embodiments of this utility model, the first bending mechanism 110 includes a pressing structure 111 and a bending structure 112. The bending structure 112 is disposed below the pressing structure 111. The pressing structure 111 is used to press and fix the workpiece on the first support platform 120. The first support platform 120 is provided with a clearance through hole 120a. The bending structure 112 can pass through the clearance 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 support platform 120 and the preset bending position of the workpiece is aligned with the clearance through hole 120a, the pressing structure 111 presses and fixes the workpiece on the first support platform 120. Then, the bending structure 112 passes through the clearance through hole 120a and pushes up the workpiece, causing the workpiece to bend at the preset bending position. Finally, the bending structure 112 resets and the pressing structure 111 is released.

[0045] It is understandable that after the bending structure 112 passes through the clearance through hole 120a, the bending structure 112 can push the workpiece to bend towards the pressing structure 111, and the bending structure 112 and the pressing structure 111 are close to each other, so that the bending angle of the workpiece is large, and the part of the workpiece located between the bending structure 112 and the pressing structure 111 forms a preset crease.

[0046] In a specific embodiment of this utility model, 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 the vertical direction so that the pressing block 111b can abut against the workpiece on the first support 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 the vertical direction so that the top block 112b can pass through the clearance through hole 120a and bend the workpiece upward.

[0047] In a further embodiment of the present invention, the first bending module 100 further includes a second position adjustment mechanism 130. The second position adjustment mechanism 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 so that the top block 112b can be aligned with the preset bending position of the workpiece.

[0048] Understandably, 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 support platform 120 or removed from the first support platform 120.

[0049] 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.

[0050] 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. Each first bending mechanism 110 is connected to a second position adjustment mechanism 130 and performs bending on different positions of the same workpiece.

[0051] 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 the two in the above embodiment.

[0052] like Figure 3 and Figure 5As shown, in some embodiments, the first support platform 120 includes a mounting frame 121, a drive structure 122, a first support plate 123, and a second support plate 124. Both the first support plate 123 and the second support plate 124 are used to support workpieces. The mounting frame 121 is provided with a temporary storage position and a bending position. The drive structure 122 is connected to the first support plate 123 and the second support plate 124 respectively, and is used to drive the first support plate 123 and the second support plate 124 to move between the temporary storage position and the bending position. The first bending mechanism 110 is provided on one side of the bending position and is used to bend the workpiece at the bending position. The transport module 200 can transport the workpiece at the temporary storage position to the second support platform 320.

[0053] Understandably, when the first support plate 123 is in the bending position, the workpiece is placed on the first support plate 123, and the first bending mechanism 110 bends the workpiece on the first support plate 123 to form a preset crease. Then, the first support plate 123 is driven to move to the temporary storage position through the drive structure 122, and the second support plate 124 in the temporary storage position is moved to the bending position. At this time, the transport module 200 can transport the bent workpiece in the temporary storage position to the second support platform 320. At the same time, the first bending mechanism 110 can bend the workpiece on the second support plate 124 in the bending position, thereby improving the bending efficiency of the first bending module 100.

[0054] Specifically, the drive structure 122 is a conveyor belt.

[0055] refer to Figure 3 and Figure 5 In some embodiments of this utility model, the temporary storage position and the bending position are distributed along a preset horizontal direction. The first bearing plate 123 is slidably disposed on the mounting frame 121 along the preset horizontal direction. The first bearing platform 120 also includes a lifting structure 125, which is slidably disposed on the mounting frame 121 along the preset horizontal direction. The second bearing plate 124 is connected to the lifting structure 125. The lifting structure 125 can drive the second bearing plate 124 to perform lifting and lowering movements so that the second bearing plate 124 can avoid the first bearing plate 123 in the vertical direction.

[0056] It is understandable that when the first support plate 123 and the second support plate 124 approach each other in a preset horizontal direction under the drive of the drive structure 122, the lifting structure 125 can make the second support plate 124 rise and fall in the vertical direction so that the second support plate 124 and the first support plate 123 are on different horizontal planes. Thus, while the first support plate 123 moves from the temporary position to the bending position, the second support plate 124 can smoothly move from the bending position to the temporary position.

[0057] like Figure 3 and Figure 5As 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 connected in sequence. The horizontal height of the second section 126b is lower than the horizontal height of the first section 126a and the third section 126c. The lifting structure 125 includes a slide block 125a and a slide rail 125b. The slide rail 125b extends vertically and is slidably disposed on the mounting frame 121 along a preset horizontal direction. The slide block 125a is slidably disposed on the slide rail 125b along a vertical direction and is connected to the second bearing plate 124. The slide block 125a is provided with a guide portion 125c, which passes through the slide groove 126.

[0058] Understandably, when the slide rail 125b slides on the mounting bracket 121 along a preset horizontal direction, the guide portion 125c of the slide block 125a slides within the slide groove 126. When the guide portion 125c is located in the first section 126a of the slide groove 126, the second support plate 124 and the first support plate 123 are distributed along a preset horizontal direction. When the guide portion 125c slides to the second section 126b of the slide groove 126, the slide block 125a moves downward in the vertical direction under the action of gravity, and the second support plate 124 descends accordingly to avoid the first support plate 123. Then, the second support plate 124 continues to move under the action of the drive structure 122, so that the guide portion 125c slides towards the third section 126c of the slide groove 126. The guide portion 125c of the slide block 125a moves upward under the support of the groove wall of the slide groove 126, and the second support plate 124 rises accordingly.

[0059] Specifically, the first segment 126a and the third segment 126c are respectively located at the bending position and the temporary storage position of the mounting bracket 121, and the first segment 126a and the third segment 126c have the same horizontal height. When the guide part 125c is located in the first segment 126a, the horizontal height of the second bearing plate 124 is the same as the horizontal height of the first bearing plate 123.

[0060] refer to Figure 2In some embodiments of this utility model, the second bending module 300 further includes a pressing mechanism 340. The pressing mechanism 340 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 closer to or further away from the second support platform 320 to press or release the workpiece on the second support platform 320. It can be understood that when the bent workpiece moves to the second support platform 320, the driver 341 drives the pressing block 342 closer to the second support platform 320 and presses the workpiece on the second support platform 320. Then, the second bending mechanism 310 repeatedly bends the workpiece along the preset crease. By pressing the workpiece on the second support platform 320 with the pressing block 342, the possibility of the workpiece's position shifting during repeated bending can be reduced, thereby affecting the bending effect of the workpiece.

[0061] like Figure 2 As shown, in one embodiment, the actuator 341 includes a rotary pressing cylinder. It is understood that, through the output end of the rotary pressing cylinder connected to the pressing block 342, when the workpiece is placed on the second support platform 320, the rotary pressing cylinder can drive the pressing block 342 to rotate forward and move downward toward the workpiece until the workpiece is pressed firmly onto the second support platform 320. After repeated bending of the workpiece is completed, the rotary pressing cylinder can drive the pressing block 342 upward and rotate in the opposite direction away from the workpiece, at which point the workpiece can be smoothly detached from the second support platform 320. By setting the rotary pressing cylinder, the workpiece does not need to avoid the pressing block 342 when being moved to or from the second support platform 320.

[0062] refer to Figure 6 In some embodiments of this utility model, the handling 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 support platform 120 and the second support platform 320. The vertical drive mechanism 230 is used to drive the adsorption mechanism 210 to move closer to or further away from the first support platform 120 or the second support 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 support platform 320.

[0063] In some embodiments of this utility model, the die-cutting system further includes a hopper 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 hopper 400 to the first support platform 120, and the unloading module 700 is used to move the repeatedly bent workpiece from the second support platform 320 to the conveyor line 500. The specific structures of the loading module 600 and the unloading module 700 refer to the specific structure of the handling module 200.

[0064] In a further embodiment of this utility model, 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 increasing the overall production efficiency of the bending device.

[0065] In some embodiments of this utility model, the first support platform 120 can fully support the edge portion of the workpiece, while the second support platform 320 can only support a portion of the edge of the workpiece. It is understood that since the preset bending position of the workpiece is located in the middle region of the workpiece, the first support platform 120 has a clearance through hole 120a so that the bending structure 112 can bend the workpiece at the preset bending position, while the edge portion of the workpiece can be supported by the workpiece. When the workpiece is bent, the bending area of ​​the workpiece tilts upwards, and the second support platform 320 only has a partial support structure to support the bending area of ​​the workpiece. This facilitates the clamping structure 313's clamping of the workpiece, and since the bending area of ​​the workpiece is only partially supported by the second support platform 320, the bending area of ​​the workpiece tends to be more horizontal under the action of force.

[0066] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
