Description

Technical Field

[0001] The utility model relates to the technical field of automatic production of flexible printed circuit boards, and particularly relates to a high-precision automatic blanking device for flexible printed circuit boards applied to the SMT industry. Background Art

[0002] The FPC flexible printed circuit board, whose full name is Flexible Printed Circuit and is abbreviated as FPC, is a circuit board made of a flexible substrate. It can be freely bent, wound, and folded, can meet the design requirements of smaller size and higher density installation, and also helps to reduce the assembly process and enhance reliability.

[0003] During the production process of flexible printed circuit boards, it is necessary to ensure that the state of the flexible printed circuit board products is in a stable state, and its blanking accuracy has a decisive impact on product quality and production efficiency.

[0004] When the FPC is blanked, the first problem to be solved is the positioning problem. Due to factors such as mechanical wear and thermal expansion, the traditional mechanical positioning method is difficult to ensure long-term stable high precision.

[0005] Secondly, how to ensure that the FPC does not displace or deform during the blanking process is another key problem. Since the flexible printed circuit board is a flexible product and its state is uncertain, when using a conventional clamping head, suction cup, or adsorption head to pick up the flexible printed circuit board, the force is directly applied to the surface of the FPC at the adsorbed or grabbed part, which is more likely to deform and damage the surface of the FPC, thus also deteriorating the positioning accuracy.

[0006] In view of this, how to solve the problem of insufficient positioning accuracy existing in the existing equipment during the FPC blanking process has become the subject to be studied and solved by the utility model. Summary of the Utility Model

[0007] The utility model provides a high-precision automatic blanking device for flexible printed circuit boards, and its purpose is to solve the problem of insufficient positioning accuracy existing in the existing equipment during the FPC blanking process.

[0008] To achieve the above purpose, the utility model proposes a high-precision automatic blanking device for flexible printed circuit boards, which is used to transfer the flexible printed circuit board in the carrier to the tray. Its innovation lies in:

[0009] The automatic blanking device includes a frame and a carrier transmission mechanism, a handling motion mechanism, an upper vision module, a picking and placing handling mechanism, and a tray mechanism installed on the frame.

[0010] The carrier transmission mechanism includes a streamline and a positioning module on the streamline for positioning the carrier.

[0011] The tray mechanism is arranged on one side of the streamline, and a tray placement area is arranged on the tray mechanism.

[0012] The handling motion mechanism straddles the transmission path of the carrier on the streamline and the tray placement area. The handling motion mechanism includes a first motion module, a second motion module, a third motion module, and a fourth motion module.

[0013] The upper vision module is positioned and connected to the second motion module, and the pick-and-place handling mechanism is positioned and connected to the fourth motion module. The second motion module is driven by the first motion module to reciprocate in the first direction, the third motion module and the upper vision module are driven by the second motion module to reciprocate in the second direction, the fourth motion module is driven by the third motion module to reciprocate in the third direction, and the pick-and-place handling mechanism is driven by the fourth motion module to rotate around the axis of the third direction.

[0014] The pick-and-place handling mechanism includes at least one steel sheet suction module and at least one product suction module. The steel sheet suction module includes a suction cup at the bottom. The product suction module includes a profiling suction head. The profiling suction head is equipped with a plurality of air nozzles arranged to match the shape of the flexible circuit board and a plurality of pads. The plurality of pads are spaced apart, and air nozzles are selectively arranged in the gap spaces between the pads.

[0016] 1. In the above technical solution of the present utility model, aiming at the problems that the traditional mechanical positioning method is difficult to ensure long-term stable high precision and the conventional material taking method is more likely to deform the surface of the FPC, which will also make the positioning accuracy worse, the high-precision automatic blanking equipment for flexible circuit boards of the present utility model is innovatively designed. A carrier transmission mechanism, a handling motion mechanism, an upper vision module, a picking and placing handling mechanism, and a tray mechanism are arranged on the frame of the high-precision automatic blanking equipment for flexible circuit boards. Among them, the handling motion mechanism drives the upper vision module to move on the transmission path of the carrier on the production line.

The second motion module drives the third motion module and the upper vision module to reciprocate in the Y direction.

The upper vision module and the third motion module are respectively installed on both sides of the connection bracket. The upper vision module includes a camera and a light source.

With the lining block of this structure, better support can be provided when adsorbing the flexible circuit board, reducing the deformation of the flexible circuit board. The design of providing chamfers on the four sides of the bottom of the lining block allows the flexible circuit board to better separate from the lower surface of the lining block when being placed (removing negative pressure) by the product suction module.

[0024] 9. In the above technical solution, the tray mechanism includes a tray roller track, a tray suction and handling module, and a tray lifting module arranged on the tray placement area.

[0064] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0065] The present utility model aims at the problems that the traditional mechanical positioning method is difficult to ensure long-term stable high precision and the conventional material taking method is more likely to deform the surface of the FPC, thereby also deteriorating the positioning accuracy. Therefore, the flexible printed circuit board high-precision automatic blanking device of the present utility model is innovatively designed to complete the high-precision automatic blanking operation of the flexible printed circuit board 9.

[0066] As shown in the attached Figure 1 to the attached Figure 12 As shown, an embodiment of the present utility model provides a flexible printed circuit board high-precision automatic blanking device for transferring the flexible printed circuit board 9 in the carrier 8 to the tray. The automatic blanking device includes a frame 1 and a carrier transmission mechanism 2, a handling motion mechanism 3, an upper vision module 4, a pick-and-place handling mechanism 5, and a tray mechanism 6 installed on the frame 1.

[0067] The carrier transmission mechanism 2 includes a streamline 21 and a positioning module 22 on the streamline 21 for positioning the carrier 8.

[0068] The tray mechanism 6 is arranged on one side of the streamline 21, and a tray placement area 601 is provided on the tray mechanism 6.

[0069] The handling and moving mechanism 3 is horizontally arranged across the transmission path of the vehicle 8 on the streamline 21 and the tray placement area 601. The handling and moving mechanism 3 includes a first moving module 31, a second moving module 32, a third moving module 33, and a fourth moving module 34.

[0070] The upper vision module 4 is positioned and connected to the second moving module 32, and the picking and placing handling mechanism 5 is positioned and connected to the fourth moving module 34. The first moving module 31 drives the second moving module 32 to reciprocate in the first direction, the second moving module 32 drives the third moving module 33 and the upper vision module 4 to reciprocate in the second direction, the third moving module 33 drives the fourth moving module 34 to reciprocate in the third direction, and the fourth moving module 34 drives the picking and placing handling mechanism 5 to rotate around the axis of the third direction.

[0071] The picking and placing handling mechanism 5 includes at least one steel sheet suction module 51 and at least one product suction module 52. The steel sheet suction module 51 includes a suction cup 511 at the bottom. The product suction module 52 includes a profiling suction head 520. The profiling suction head 520 is equipped with a plurality of air nozzles 522 arranged to match the shape of the flexible circuit board 9 and a plurality of lining blocks 521. The plurality of lining blocks 521 are arranged at intervals, and air nozzles 522 are selectively arranged in the gap spaces between the lining blocks 521. The air at the air nozzles 522 is sucked out through a vacuum pipeline to form a low-pressure area 523 located between the lining blocks 521 and at the air nozzles 522.

[0072] The working process of the embodiment of the present utility model can be referred to as follows:

[0073] 1. The vehicle 8 is transferred from the streamline 21 of the vehicle transfer mechanism 2 to the blanking station, and then is positioned and clamped by the positioning module 22.

[0074] 2. The upper vision module 4 moves above the vehicle 8 positioned on the streamline 21 to take a photo, and accurately identifies the position and direction of the flexible circuit board 9 through the image.

[0075] 3. The steel sheet suction module 51 transports the steel sheet 82 for fixing the flexible circuit board 9 on the vehicle 8 to the initial position 81 of the steel sheet on the vehicle 8.

[0076] 4. Then, the handling and moving mechanism 3 drives the product suction module 52 with the profiling suction head 520 to adsorb the flexible circuit board 9 according to the identified position and direction of the flexible circuit board 9, and transfers the flexible circuit board 9 to the tray in the tray placement area 601, thereby completing the high-precision automatic blanking operation of the flexible circuit board 9.

[0077] Through the implementation of the above embodiments of the present utility model, in this device, the upper vision module 4 takes pictures and accurately identifies the position and orientation of the flexible circuit board 9 through images, realizing the accurate identification and tracking of the positioning of the flexible circuit board 9, thereby improving the positioning accuracy. And the product suction module 52 with a profiling suction head 520 is used to cooperate with the adsorption and clamping of the flexible circuit board 9. By generating a local low pressure, the flexible circuit board 9 is stably clamped, avoiding damage to it and also avoiding over deformation resulting in inaccurate positioning during blanking. By using such a high-precision automatic blanking device and applying it to an automated production line, the handling, positioning, and blanking of the flexible circuit board 9 are completed by automated equipment, reducing human errors, improving the positioning accuracy, and improving the production efficiency.

[0078] As Figure 1 shown in the XYZ coordinate system, in another embodiment of the present utility model, the length extension direction of the streamline 21 is the Y direction. The first motion module 31 drives the second motion module 32 to reciprocate in the X direction. The second motion module 32 drives the third motion module 33 and the upper vision module 4 to reciprocate in the Y direction. The third motion module 33 drives the fourth motion module 34 to reciprocate in the Z direction. The fourth motion module 34 drives the picking and placing handling mechanism 5 to rotate around the Z axis. In this way, the movements of the respective carriers 8, the upper vision module 4, and the picking and placing handling mechanism 5 are more reasonable, making the structure of the device more compact, reducing the floor area, and facilitating the utilization, upgrading, and transformation of the factory building space. Reference can be made to Figure 12 the schematic diagram after the cover 7 is assembled as shown, with a compact overall structure and a small footprint.

[0079] In another embodiment of the present utility model, the movement trajectories of the upper vision module 4 and the picking and placing handling mechanism 5 at least cover part of the transmission path of the carrier 8 on the streamline 21 and part of the tray placement area 601. In this way, it can meet the requirements of taking pictures, image recognition, and transfer of the flexible circuit board 9, and has a wider application range.

[0080] In another embodiment of the present utility model, a connecting bracket 35 is provided at the driving end of the second motion module 32. The upper vision module 4 and the third motion module 33 are respectively installed on both sides of the connecting bracket 35. The upper vision module 4 includes a camera 41 and a light source 42. Thus, the purpose that the second motion module 32 can drive the upper vision module 4 and the picking and placing handling mechanism 5 to move together in the Y direction is achieved, and the device is also made more compact and the movement is more reasonable.

[0081] As Figure 11As shown, in another embodiment of the present utility model, the positioning module 22 includes a clamping drive unit 221, a clamping plate 222, and an induction unit 223. The induction unit 223 is arranged between the flow lines 21. When the flow lines 21 transfer the carrier 8 to the blanking position, the carrier 8 is sensed by the induction unit 223, and the clamping drive unit 221 drives the clamping plate 222 to position and clamp the carrier 8.

[0082] As Figures 5 to 7 shown, in another embodiment of the present utility model, the number of the steel sheet suction modules 51 and the product suction modules 52 is two each. The steel sheet suction modules 51 and the product suction modules 52 are both installed on the adjustment frame 53, and the adjustment frame 53 is fixedly connected to the bottom of the fourth motion module 34. In this way, the steel sheet suction modules 51 and the product suction modules 52 can be better connected and fixed to the fourth motion module 34, and the fourth motion module 34 drives the steel sheet suction modules 51 and the product suction modules 52 to rotate synchronously. Specifically, the two steel sheet suction modules 51 are arranged in the middle of the two product suction modules 52 to adapt to the carrier 8 loaded with two flexible circuit boards 9, and the initial positions 81 of the steel sheets of the carrier 8 are located at two middle positions of the carrier 8.

[0083] As Figure 8 shown, in another embodiment of the present utility model, the lining block 521 is a block structure with a trapezoidal cube at the bottom. Chamfers 5211 are provided on four sides of the bottom of the lining block 521. The lower surface of the lining block 521 serves as the support surface 5210 after adsorbing the flexible circuit board 9. Multiple lining blocks 521 are arranged in a shape matching the vertical projection of the flexible circuit board 9. The lower cross-sectional area of the trapezoidal cube is larger than the upper cross-sectional area. With the lining block 521 of this structure, it can better support the flexible circuit board 9 during adsorption and reduce the deformation of the flexible circuit board 9. The design of providing chamfers 5211 on four sides of the bottom of the lining block 521 enables the flexible circuit board 9 to better separate from the lower surface of the lining block 521 when being put down (removing negative pressure) by the product suction module 52.

[0084] In another embodiment of the present utility model, the tray mechanism 6 includes a tray roller track 61 arranged on the tray placement area 601, a tray adsorption and handling module 62, and a tray lifting module 63. The tray roller track 61 is provided with a full tray placement area and an empty tray placement area on the outer side of the frame 1, so as to better place and replace the trays for feeding and carrying the flexible circuit board 9, and multiple trays can be stacked in batches. Specifically, the tray adsorption and handling module 62 includes a fifth motion module 621, a sixth motion module 622, and a tray adsorption head 623. The fifth motion module 621 is horizontally arranged on the tray placement area 601, and drives the sixth motion module 622 to reciprocate along the Y direction, and the sixth motion module 622 drives the tray adsorption head 623 to reciprocate along the Z direction; as Figure 9 , Figure 10 shown, the tray lifting module 63 includes a lifting roller bracket 631 and a lifting drive unit 632, so as to make the transfer of the tray more reasonable and fast, and can adjust the tray position in cooperation with the stroke height and stroke distance of the picking and placing handling mechanism 5. More specifically, a defective product placement area 602 is also arranged on one side of the tray placement area 601 on the frame 1, so as to place defective products.

[0085] After adopting the above more specific implementation manner, the specific process can be referred to as follows:

[0086] 1. The carrier 8 is transferred from the streamline 21 of the carrier transmission mechanism 2 to the feeding station, and then is positioned and clamped by the positioning module 22.

[0087] 2. The upper vision module 4 moves above the carrier 8 positioned on the streamline 21 to take a photo, accurately identifies the position and direction of the flexible circuit board 9 through the image, and obtains the product detection information according to the interaction between the carrier 8 code on the carrier 8 and MES.

[0088] 3. The steel sheet suction module 51 transports the steel sheet 82 used to fix the flexible circuit board 9 on the carrier 8 to the initial position 81 of the steel sheet on the carrier 8.

[0089] 4. Then the handling motion mechanism 3 drives the product suction module 52 with the profiling suction head 520 to adsorb the flexible circuit board 9 according to the identified position and direction of the flexible circuit board 9.

[0090] 5. Classify according to the product detection information, put the OK products into the trays, and put the NG products into the defective product area.

[0091] 6. The positioning module 22 releases the carrier 8, and the carrier 8 flows out of the equipment.

[0092] It should also be noted that in the embodiments of the present invention, the control of each module and mechanism belongs to the prior art, and those skilled in the art are aware of their principles and structures. These technologies are not the focus of the present invention, so no further description will be given here.

[0093] In addition, in the present application, the mechanism or module or unit for linear motion, such as the first motion module 31, the second motion module 32, the third motion module 33, the fifth motion module 621, the sixth motion module 622, the clamping drive unit 221, etc., can adopt one of the following mechanisms:
