Description

Technical Field

[0001] This utility model relates to the field of bending technology, and in particular to an automatic bending device for FPC with a vibration motor. Background Technology

[0002] Flexible printed circuit boards (FPCs) are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. They are characterized by high wiring density, light weight, and thinness.

[0003] In the manufacturing of vibration motors, FPC boards require special bending processes. Because bending is difficult to achieve, the current approach is to avoid bending FPC boards as much as possible. When bending is necessary, it is done manually. However, manual bending introduces the unstable factor of human labor, resulting in inconsistent bending quality and accuracy. Manually folded FPC boards are prone to springback, leading to poor bending results and compromising the yield rate after assembly into the phone. Furthermore, manual bending operations result in low production efficiency.

[0004] Later, a bending machine appeared on the market that automates the bending of FPC boards. Compared with manual bending, it ensures bending quality and accuracy. However, this bending machine is not equipped with a device for shaping after bending, which means that the bent FPC needs to be shaped by another shaping machine. This results in the intermediate products needing to be transferred between different machines, which consumes a lot of manpower and resources, and the operation and control are troublesome. For the shaping process, the bent FPC needs to be placed on the shaping machine for operation. The series of actions of loading and unloading takes a lot of time, resulting in a long process time and limiting the improvement of production efficiency.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

Through the design of the limiting block 253 and the second positioning block 244, under the drive of the seventh driving device 252 and the ninth driving device 243 respectively, the limiting block 253 is controlled to abut against one side of the bending point of the first section of the FPC, and the second positioning block 244 is controlled to be tightly attached to the other side of the bending point of the first section of the FPC, thereby forming a double positioning of the first bending section, so as to improve the bending accuracy of the second bending mechanism 20A when bending the second section of the FPC, and ensure the yield of the product.

[0108] Preferably, the second FPC bending module 20 further includes a fourth driving device 28 and a fifth driving device 29; the fourth driving device 28 is arranged obliquely, and the fifth driving device 29 is connected to the fourth driving device 28 through a second adapter plate 202A; the second bending mechanism 20A is connected to the fifth driving device 29 through a second connecting plate 201A; the fourth driving device 28 controls the second adapter plate 202A to move obliquely back and forth; the fifth driving device 29 controls the second connecting plate 201A to move back and forth along the extension direction of the second adapter plate 202A; the third pressing and shaping mechanism 27 is disposed at one end of the second clamping fixture 211 and located beside the second bending mechanism 20A;

[0109] The second bending mechanism 20A includes a rotary drive device 203A and a second bending block 204A. The output end of the rotary drive device 203A is connected to the second bending block 204A via a synchronous belt drive unit 205A to control the second bending block 204A to push one end of the second segment of the FPC toward the second positioning block 244 for bending. The bending angle of the second segment is set to 30 degrees. When the third positioning block 263, the limiting block 253, and the second positioning block 244 are positioned and limited, the second bending block 204A pushes one end of the second segment of the FPC toward the second positioning block 244 for bending. Figure 10 As shown, the angle between the second segment 42 and the first segment is 37 degrees. In this embodiment, the bending angle of the first segment and the bending angle of the second segment can be selected according to the actual situation.

[0110] The third pressing and shaping mechanism 27 includes a third Y-axis translation mechanism 271, a sixth support frame 272, a tenth drive device 273, and a third shaping block 274. The sixth support frame 272 is mounted on the third Y-axis translation mechanism 271, which controls the sixth support frame 272 to move back and forth along the Y-axis. The tenth drive device 273 is mounted on the sixth support frame 272 and connected to the third shaping block 274. The third shaping block 274 is positioned above the second clamping fixture 211, and the tenth drive device 273 controls the third shaping block 274 to move obliquely back and forth, causing the third shaping block 274 to abut against the bending point of the second segment of the FPC. The third shaping block 274 has a clearance notch. After the second segment of the FPC is bent, it is pressed and shaped by the third pressing and shaping mechanism 27 to ensure the accuracy of the bent second segment of the FPC and avoid springback.

[0111] The general working process of this embodiment is described in detail below:

[0112] First, a vibration motor with an FPC is mounted on the first clamping fixture 13. Then, the first Z-axis translation mechanism 15 controls the first positioning mechanism 16 and the first pressing mechanism to press downwards toward the first clamping fixture 13. Subsequently, the position of the first Z-axis translation mechanism 15 in the Y-axis direction is adjusted by the first Y-axis translation mechanism 14, so that the first positioning block 162 of the first positioning mechanism 16 is tightly attached to one end of the first section of the FPC on the vibration motor. The first pressing head abuts against the housing of the vibration motor for pressing and limiting. Then...

[0113] The first driving device 112 drives the first bending block 113 to move upward, so that the first bending block 113 contacts the first section of the vibration motor FPC. Then, the first X-axis translation mechanism 17 controls the second Y-axis translation mechanism 18 to move along the X-axis direction, thereby linking the first bending block 113 to push the other end of the first section of the vibration motor FPC towards the first positioning block 162.

[0114] After the first section is bent, the second drive device 102A controls the first shaping block 101A to move along the X direction, so that the first shaping block 101A abuts against the bending point of the first section of the FPC. At this time, the first shaping block 101A applies a pushing force to the bending point of the first section. Under the action of the first positioning block 162, the first bending point will not deform; then

[0115] The third drive device 102B controls the second shaping block 101B to move along the Y direction, so that the second shaping block 101B abuts against the bending point of the first segment of the FPC;

[0116] After the first section of the FPC is bent and pressed into shape, the semi-finished product on the first clamping fixture 13 is transferred to the second clamping fixture 211 of the second FPC bending module 20 via the bending and transport module 30. Then, the sixth drive device 262 controls the third positioning block 263 to move upward, and then the third X-axis translation mechanism 22 adjusts the position of the third positioning mechanism 26 to be close to one side of the first bending point of the FPC. Then, the seventh drive device 252 drives the limiting block 253 to move upward, so that the limiting block 253 abuts against the other side of the first bending point of the FPC. Then, the ninth drive device 243 drives the second positioning block 244 to move upward, and then the ninth drive device 243 controls the second positioning block 244 to move toward the FPC. Then, the eighth drive device 241 adjusts the position of the second positioning block 244. When the third positioning block 263 and the limiting block 253 are in contact with each other, the second positioning block 263 moves upward. After the positioning and limiting of the second positioning block 244 is completed, the fifth driving device 29 drives the second bending mechanism 20A to move downward. Then, the fourth driving device 28 adjusts the position of the second bending mechanism 20A so that it is close to the second bending segment. Then, the output end of the rotary driving device 203A is connected to the second bending block 204A through the synchronous belt drive unit 205A to control the second bending block 204A to push one end of the second segment of FPC toward the second positioning block 244 to bend. After the second segment is bent, the third pressing and shaping mechanism 27 is driven to move by the third Y-axis translation mechanism 271 so that the third pressing and shaping mechanism 27 pre-positions the second segment of FPC that needs to be pressed and shaped. Then, the tenth driving device 273 controls the third shaping block 274 to move obliquely so that the third shaping head abuts above the bending point of the second segment of FPC for pressing and shaping.

[0117] The key design feature of this invention lies in its structural design of a first-section FPC bending module and a second-section FPC bending module. The first-section FPC bending module includes a first bending mechanism and a first-section pressing and shaping mechanism; the second-section FPC bending module includes a second bending mechanism and a second-section pressing and shaping mechanism. Thus, after the first and second sections of the FPC board are bent, the first and second pressing and shaping mechanisms respectively press and shape the first and second bends, ensuring that the bending angle is fixed and does not rebound, resulting in high bending efficiency. This achieves integrated bending and pressing and shaping of both sections of the FPC board, reducing manual labor, improving production efficiency, and lowering production costs.

[0118] Secondly, the design of the bending and handling module is ingenious. It creates displacement of the product to be processed in the X and Z directions, resulting in high working stability. Compared with the material handling method of a robotic arm, it has a simple structure and occupies less space.

[0119] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
