Abstract
Description
Technical Field
[0001] The present application relates to the technical field of flexible circuit board processing, and in particular to an FPC picking device, a robotic arm, and a production line. Background Art
[0002] The QR code process for flexible printed circuit boards involves printing a white ink block on the FPC, then laser engraving the image onto the white ink using a QR code reader.

Otherwise, inconsistent stacking orientations can easily lead to equipment recognition errors and frequent alarms and shutdowns during sorting. In particular, if the white ink on the product is designed to be uniform and consistent horizontally and vertically, the front and back sides cannot be clearly distinguished, which can easily cause the QR code to be printed in reverse.

[0033] Reference Figure 1 The FPC picking device of the first embodiment of the present application is used for identifying and picking up flexible circuit boards (FPCs) of electronic products. The FPC picking device includes a driving component 100, a suction cup component 200, a CCD capture component 300 and a control device.
[0034] The driving component 100 is installed on the robotic arm; the suction cup component 200 is connected to the driving component 100, and the driving component 100 is used to drive the suction cup component 200 to move. The suction cup component 200 includes a lifting and rotating component 230, a tray component 210 and a suction cup body 220 arranged on the tray component 210, and the lifting and rotating component 230 is used to drive the tray component 210 to rotate and / or lift; the CCD capture component 300 is arranged on the tray component 210; the control device is configured to be able to receive information on the positioning and identification of the CCD capture component 300, and to be able to control the actions of the driving component 100 and the suction cup body 220 respectively.
[0035] As you can understand, the CCD capture component 300, which enables high-precision automatic identification, handling, and correction of FPCs, is mounted on the robot's tray assembly 210 and works in conjunction with the suction cup component 200 and drive component 100 already mounted on the robot. Products are placed centrally at the loading port. The robot first moves above the board removal position, where it uses the CCD to locate and capture the product's identification points. The robot then picks up the product, hovers over the unloading area, adjusts its orientation, and places it into the work area, thus achieving high-precision directional identification.
[0036] Reference Figure 1The FPC picking device of the first embodiment of the present application locates and identifies the FPC by adding a CCD capture component 300 to the FPC picking device, and controls the driving component 100 through the control device to cooperate with the CCD capture component 300 to locate the image, and finally uses the lifting and rotating component 230 to perform correction and regulation to unify the operation direction, thereby reducing the alarm shutdown caused by product inconsistency, replacing traditional manual adjustment or shutdown to handle such abnormal situations as much as possible, improving production efficiency and reducing the alarm probability, and avoiding as much as possible the reduction in efficiency or poor quality due to manual picking or neglect of the front and back of the product.
[0037] In some embodiments of the present application, a mounting position is hollowed out on the tray assembly 210, and the CCD capture component 300 includes an identification lens, which is embedded in the mounting position and installed on the tray assembly 210. It is understood that the tray assembly 210 of the factory robot is modified to increase the CCD mounting position, find the center point on the plate of the original tray assembly 210, drill a hole, install the CCD lens, and connect it to the device software for debugging or upgrading the software to be compatible with the robot arm operation package.
[0038] In some embodiments, after punching, products can be identified and locked using graphics or text on each product, or by capturing images of location points to automatically generate reference image points for identification. During operation, the robotic arm can grasp the product using a first-identification, then-operation method, then adjust the product's orientation in mid-air before loading it onto the work platform for product coding.
[0039] In some embodiments of the present application, multiple suction cup bodies 220 are provided and evenly spaced relative to the center of the tray assembly 210. It is understood that the even distribution of the suction cup bodies 220 ensures that the suction cup bodies 220 can securely grasp the material. In some embodiments, the suction cup bodies 220 are magnetically adjustable on the tray assembly 210. It is understood that the relative positions of the suction cup bodies 220 can be adaptively adjusted based on the different specifications of the product, thereby ensuring more stable material grasping and reducing accidents.
[0040] In some embodiments, the mounting location is set at a central position. It is understood that by installing it at a central position, it is convenient to debug or upgrade the device software, thereby improving compatibility. At the same time, the slot at the central position does not require excessive modification to the tray assembly 210 of the robot, thereby saving costs and achieving the effect of the robot automatically identifying and correcting the front and back of the same side of the product.
[0041] In some embodiments, the suction cup body 220 can also be installed on the tray assembly 210 through other common installation methods, and can be installed in a fixed or adjustable manner according to actual needs.
[0042] In some embodiments of the present application, the driving component 100 includes a rotating and telescopic component 120, which is used to drive the lifting and rotating component 230 to rotate and / or lift. It can be understood that the rotating and telescopic component 120 is connected to the robotic arm, and the rotating and telescopic component 120 is used to first drive the lifting and rotating component 230 to adjust its position, so that the lifting and rotating component 230, the suction cup component 200, and the CCD capture component 300 can reach a preset position, or so that the CCD capture component 300 can accurately locate and identify the various position points of the product for judgment. Then, the lifting and rotating component 230 is used to drive the suction cup component 200 to rotate and / or lift so that the suction cup component 200 can smoothly grab the material, and then the lifting and rotating component 230 is used to achieve the effect of correcting and adjusting the front and back sides to a unified operation direction.
[0043] In some embodiments, the rotating telescopic assembly 120 is connected to the X-axis drive assembly of the robotic arm, thereby enabling the suction cup component 200 and the material to achieve multi-degree-of-freedom movement.
[0044] In some embodiments of the present application, the rotary telescopic assembly 120 includes a lifting guide rod, a rotating bracket 121, a lifting drive, and a rotating drive. The lifting drive is used to drive the lifting guide rod to move upward and downward. The rotating drive and rotating bracket 121 are disposed on the lifting guide rod. The rotating drive is used to drive the rotating bracket 121 to rotate. The lifting and rotating assembly 230 is disposed on the rotating bracket 121. It will be understood that the provision of the lifting drive and rotating drive enables the suction cup component 200 and the CCD capture component 300 to adaptively move and achieve corresponding effects, thereby improving recognition accuracy, increasing production efficiency, and reducing the probability of alarms.
[0045] In some embodiments, the rotating bracket 121 includes at least one arm, each arm is provided with a lifting and rotating assembly 230 and a suction cup component 200, and each suction cup component 200 can move synchronously or separately to adapt to different picking requirements and improve production efficiency.
[0046] In some embodiments of the present application, a buffer pad is provided between the lifting and rotating assembly 230 and the suction cup component 200. It is understandable that the provision of the buffer pad can play a transition and anti-collision effect, and can also eliminate a certain installation gap and improve control accuracy.
[0047] Transition rubber pads are installed to ensure anti-collision clearance.
[0048] In some embodiments, the buffer pad may be a rubber pad or other flexible pad.
[0049] Reference Figure 1The robotic arm of the second aspect embodiment of the present application can be a robotic arm or a robotic arm such as a picking robotic arm for loading materials. The robotic arm includes the FPC picking device of the first aspect embodiment of the present application. Through the setting method of high-precision automatic recognition, picking and correction of FPC, the robotic arm with this FPC picking device has the function of automatically identifying the front and back of products on the same side.
[0050] Reference Figure 1 The production line of the third embodiment of the present application can be a production line for processing flexible circuit boards (FPCs). The production line includes the robotic arm of the second embodiment of the present application, and the robotic arm includes the FPC picking device of the first embodiment of the present application, and has the function of high-precision automatic recognition, picking and correction of FPCs. At the same time, the production line also includes fully automatic equipment and workshops such as fully automatic punching machines and fully automatic QR code machines. The loading robotic arm is modified and upgraded by placing a suction cup flat plate as the base point, and the center point of the flat plate is hollowed out and inlaid with a CCD automatic recognition lens. The arm suction cup can rotate 180° and cooperate with the set positioning image to correct and control the unified operation direction. This enables the FPC picking device to achieve the function of the robotic arm automatically identifying and correcting the front and back of the same side of the product to achieve automatic recognition, thereby improving the QR code operation efficiency by ≥50% and reducing the alarm shutdown caused by product inconsistency; replacing traditional manual adjustment or shutdown to handle such anomalies, improving production efficiency and reducing the probability of alarms. Avoid reduced efficiency or poor quality due to manual picking or negligence of the front and back of the product.
