Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 to fig. 3 are a schematic diagram of a flexible circuit board processing apparatus, a schematic diagram of a flexible circuit board, and a schematic diagram of a protective film according to an embodiment of the present application. As shown, the flexible circuit board processing apparatus 1 is used to process a workpiece 2. More specifically, the workpiece 2 is a flexible circuit board. The workpiece 2 is composed of a substrate 20 and a wiring 21. Wherein, one end of the line 21 is a portion to be bent 210. In the processing process, the portion to be bent 210 is bent toward the substrate 20 with the bending line 211 as an axis and is attached to the substrate 20. Further, in order to prevent the bent portion to be bent 210 from being damaged, the protective film 3 is also attached to the bent portion to be bent 210.

The flexible circuit board processing device 1 includes a base frame 10, a stage 11, a fixing assembly 12, and a flipping assembly 13. A stage 11 is provided on the top surface of the base frame 10, the stage 11 being configured to place the workpiece 2. The fixing assembly 12 is disposed on one side of the base frame 10, and the fixing assembly 12 is configured to fix the workpiece 2. The flip assembly 13 is pivotally connected to one side of the base frame 10, and the flip assembly 13 includes a cover plate 130 and a flip member 133. The cover plate 130 has a receiving groove 131 and a positioning pin 132, the receiving groove 131 is configured to receive the portion to be bent 210 of the workpiece 2, and the positioning pin 132 is configured to position the protective film 3. The flip member 133 is fixedly coupled to the cover plate 130.

When the flip member 133 drives the cover plate 130 to flip toward the stage 11, the portion to be bent 210 of the workpiece 2 is bent toward the workpiece 2, and the protective film 3 covers the workpiece 2. Thus, the flexible circuit board processing device 1 of the present application can realize automatic processing with high accuracy. In order to make the technical features and technical ergonomics of the present application more apparent, each of the above-described elements will be explained in detail hereinafter.

The base frame 10 is used to carry the associated components thereon. In some embodiments, the base frame 10 may be composed of a substrate 100 and a supporting base 101. The substrate 100 is disposed on a support base 101. The supporting base 101 may have a shock-proof structure, such as a pneumatic shock-proof structure, to prevent shock from external environment. However, the present application is not limited thereto. In other embodiments, the base frame 10 may be an integrally formed shockproof table, which may improve the precision of product assembly through shockproof structures.

The stage 11 is provided on the base frame 10, and is configured to place the workpiece 2. The carrier 11 may have a size and shape corresponding to the workpiece 2. In this way, the workpiece 2 can be aligned more accurately with the stage 11. Therefore, in some embodiments, the stage 11 may be configured in plurality. Each carrier 11 has a different size and shape and is removably mounted to the base 10. For example, the carrier 11 may be fixed to the base by locking, engaging, or other methods known to those skilled in the art. In this case, by replacing the stage 11 corresponding to a different workpiece 2, the workpiece 2 can be more easily and accurately placed on the flexible circuit board processing apparatus 1.

Please refer to fig. 4 and fig. 5, which are a schematic diagram and an exploded view of a fixing assembly according to an embodiment of the present application, respectively. As shown, the fixing assembly 12 may include a fixing base 120, a hub 121, and a rotating member 122.

The fixing base 120 is disposed on the base frame 10. For example, the fixing base 120 may be disposed on the base frame 10 by locking, adhering, or engaging, but is not limited thereto. The fixed base 120 is used for carrying the axle element 121 and the rotating element 122 thereon, and a slot 1222 is formed through the top side of the rotating element 122.

The axle element 121 is fixedly disposed on the fixing base 120. One end of the shaft member 121 is movably fixed on the fixing base 120, the shaft member 121 can be, but not limited to, fixed on the fixing base 120 by a screw or a snap, and the other end of the shaft member 121 has an abutting head 1210. The abutment head 1210 has a diameter larger than the inner diameter of the rotary member 122 to prevent the rotary member 122 from being detached from the other end of the hub 121.

The slot 1222 of the rotating element 122 is configured to be assembled to the hub 121. In addition, one end of the rotary member 122 has an abutting portion 1220. The rotary member 122 is configured to bring the abutting portion 1220 against one side of the workpiece 2. More specifically, the rotating member 122 rotates on the fixing base 120 along a horizontal direction with the axial member 121 as an axis. When the rotating member 122 rotates by a specific angle, the abutting portion 1220 of the rotating member 122 changes from being oriented in the first direction DR1 to being oriented in the second direction DR 2. The abutting portion 1220 facing the second direction DR2 is located above the workpiece 2 and abuts against one side of the workpiece 2. In this way, the abutting portion 1220 abuts against the workpiece 2, so that the workpiece 2 is not displaced in the subsequent bending process and the film attaching process, thereby preventing processing failure.

In some embodiments, the securing assembly 12 may further include a resilient member 123. The elastic element 123 is sleeved on the axial element 121, and two ends of the elastic element 123 respectively abut against the rotating element 122 and one end of the axial element 121. More specifically, two ends of the elastic element 123 respectively abut against the inner wall of the slot in the rotating element 122 and the abutting head 1210 of the axial element 121. The distance between the rotating element 122 and the abutting head 1210 is smaller than the length of the elastic element 123 in the relaxed state, so that the elastic element 123 is in the compressed state. The elastic member 123 in the compressed state can and continuously press against the rotating member 122 and the abutting head 1210. In this way, the abutting portion 1220 of the rotating member 122 can maintain a certain downward pressure to more firmly press against the workpiece 2.

In some embodiments, the fixing base 120 has a first position-limiting portion 1200, the rotating member 122 has a second position-limiting portion 1221, and the first position-limiting portion 1200 and the second position-limiting portion 1221 are abutted to each other to limit the rotation range of the rotating member 122. In the present embodiment, the first position-limiting portion 1200 is a protrusion protruding from the rotating element 122, and the second position-limiting portion 1221 is a groove in the fixing base 120. The rotation member 122 can be moved in a certain angular range by restricting the moving range of the convex portion by the groove. For example, the angle may be between 0 ° and 90 °, or the angle may be between 0 ° and 60 °, depending on the actual usage.

Please refer back to fig. 1. As shown, the turning assembly 13 is pivotally connected to one side of the base frame 10, and the turning assembly 13 includes a cover plate 130 and a turning member 133. The flip member 133 is fixedly connected to the cover plate 130 and is used for driving the cover plate 130 to flip around the first direction DR1 to get close to or far away from the carrier 11. For example, the turning member 133 may be a dc motor that turns the cover 130 by converting electric power into mechanical energy, or turns the cover 130 by hand or other external devices. However, the present application is not limited thereto, and in other embodiments, the reversing element 133 may also be an ac motor or a pulse motor, etc. having the same or similar driving effect, so as to achieve the same effect.

The cover plate 130 is pivotally connected to one side of the base frame 10 by a flip member 133, and the cover plate 130 has a receiving groove 131 and a positioning pin 132. The receiving groove 131 is configured to receive the portion to be bent 210 of the workpiece 2, that is, the shape of the receiving groove 131 and the portion to be bent 210 correspond to each other. The positioning pins 132 are configured to position the protective film 3. More specifically, the positioning pin 132 can penetrate through the positioning through hole 30 (shown in fig. 3) of the protection film 3 to position the protection film 3 and move the protection film 3.

Please refer to fig. 6 and fig. 7, which are a schematic view and an exploded view of a positioning pin according to an embodiment of the present application. As shown, in some embodiments, the positioning pin 132 may include a positioning member 1320 and a retaining seat 1324.

The positioning member 1320 has an engaging portion 1321, and a positioning end 1322 and a connecting end 1323 located at both ends of the engaging portion 1321. Through holes 1301 (shown in fig. 1) are formed in the cover plate 130 at positions corresponding to the positioning pins 132, and the positioning ends 1322 correspondingly penetrate through the through holes 1301 and protrude out of the surface of the cover plate 130. The positioning end 1322 is used to pass through the positioning penetration hole 30 of the protective film 3, and thus, the positioning end 1322 may have a size and shape corresponding to the positioning penetration hole 30. The engaging portion 1321 and the connecting end 1323 are inserted into the cover plate 130. The engaging portion 1321 is used to engage with the cover plate 130 to prevent the positioning element 1320 from disengaging from the cover plate 130. The connecting end 1323 is used for connecting the fixing seat 1324.

The fixing seat 1324 is disposed on a surface of the cover plate 130 away from the positioning end 1322, and is sleeved on the connecting end 1323. The fixing seat 1324 is used to position the positioning member 1320 on the cover plate 130.

In some embodiments, the positioning pin 132 may further include an elastic member 1325, and the elastic member 1325 is sleeved on the connection end 1323. One end of the elastic element 1325 abuts against the accommodation slot 13240 in the fixing seat 1324, and the other end abuts against the engaging portion 1321. When the positioning element 1320 is driven by the cover plate 130 to approach the workpiece 2, the elastic element 1325 can provide a space for the positioning element 1320 to extend (i.e., the positioning element 1320 presses the elastic element 1325 in a direction toward the fixing seat 1324) so as to prevent the positioning element 1320 from pressing the workpiece 2.

Please refer to fig. 8 and fig. 9, which are another schematic diagram of a flexible circuit board processing apparatus according to an embodiment of the present application and an enlarged schematic diagram of a region a in fig. 8, respectively. As shown, in some embodiments, the flexible circuit board processing apparatus 1 may further include a suction assembly 14, and the suction assembly 14 is disposed on the cover plate 130 and configured to suck the protective film 3. Therefore, the suction assembly 14 may be disposed around the positioning pins 132 and assist the positioning pins 132 in positioning the protective film 3.

In some embodiments, the extraction assembly 14 includes a base 140 and an air extraction member 141. The base 140 is disposed on two sides of the positioning pin 132, and a plurality of air suction holes 1400 are disposed on the base 140 at intervals. The air exhausting member 141 is disposed on the cover plate 130. More specifically, the pumping member 141 is disposed on the rear surface (i.e., the side away from the pumping hole 1400) of the cover plate 130. The air suction member 141 is communicated with the air suction hole 1400, and adsorbs the protective film 3 through the air suction hole 1400. The air suction member 141 may be, for example, an electric suction pump, and sucks air by a pressure difference. However, the present application is not limited thereto, and the pumping member 141 may be a micro air pump, a small electric air pump, a high pressure air pump, or any air pump recognized by those skilled in the art. By means of the suction assembly 14, the positioning of the protective film 3 can be made more stable.

Referring to fig. 1, and also referring to fig. 10 and fig. 11, there are shown another schematic diagram of a flexible circuit board processing apparatus according to an embodiment of the present application and an enlarged schematic diagram of a region B in fig. 10. As shown, in some embodiments, the pedestal 10 may also have support posts 15 on the top surface. The supporting posts 15 are used for supporting the post cover 130 to prevent the cover 130 from over-rotating and damaging the workpiece 2. That is, the height of the support column 15 in the vertical direction may be slightly greater than or equal to the thickness of the workpiece 2 (including the portion to be bent 210). In some embodiments, the number of the support columns 15 may be one or more, and may be disposed on the top surface of the base frame 10 as the case may be.

As shown in fig. 1, in some embodiments, the base frame 10 may further have positioning posts 16 on the top surface thereof. The positioning post 16 is used for positioning the workpiece 2. In other words, the positioning posts 16 may be multiple in number and arranged at intervals around the carrier 11. However, the present application is not limited thereto, and in other embodiments, the positioning posts 16 may be disposed only at four corners of the stage 11 to provide a wider working space.

Hereinafter, a bending process and a film attaching process of the flexible circuit board will be described by taking a state diagram of the flexible circuit board processing apparatus as an example. Please refer to fig. 12-15, which are schematic views illustrating processing states according to an embodiment of the present application. As shown in fig. 12, the workpiece 2 is placed on the carrier 11 on the base frame 10, and the portion to be bent 210 of the workpiece 2 is located in the receiving groove 131 of the cover plate 130. As shown in fig. 13, the cover 130 is rotated by the flipper 133 by about 45 ° toward the workpiece 2 (which may be defined as a range of ± 10% of the value). In this way, the portion 210 to be bent of the workpiece 2 is bent by about 45 ° about the bending line 211. As shown in fig. 14, after the cover plate 130 is returned by the reversing member 133, the protective film 3 is disposed on the positioning pins 132. More specifically, the positioning pin 132 passes through the positioning penetration hole 30 of the protective film 3. In addition to this, it is also possible to more firmly position the protective film 3 by the suction assembly 14. As shown in fig. 15, the cover 130 is rotated by the flipper 133 by approximately 90 ° toward the workpiece 2. In this way, the portion 210 to be bent of the workpiece 2 is bent by about 90 ° about the bending line 211 and is attached to the substrate 20. In addition, the protective film 3 is also stuck to the bent portion to be bent 210. Please refer to fig. 16, which is a schematic diagram of a flexible circuit board after being processed according to an embodiment of the present application. After the processing of fig. 12-15, a product as shown in fig. 16 can be obtained.

In conclusion, the belt bending part of the workpiece can be bent through the accommodating groove in the turnover assembly, or the protective film can be adhered to the workpiece through the positioning pin on the turnover assembly. Further, the securing assembly may prevent the workpiece from shifting during machining. Therefore, the flexible circuit board processing device is automatic and high in precision, and the problems of high cost and low quality caused by manual assembly in the prior art are solved.
