Description

Technical Field

[0001] The present application relates to the technical field of FPC board processing, and in particular to an FPC punching machine. Background Art

[0002] FPC is a highly reliable and flexible printed circuit board made of polyimide or polyester film as the base material. It has the characteristics of high wiring density, light weight, thin thickness and good bendability.

[0003] During the production process, when defective FPC products appear, they need to be punched and marked to prevent them from being mixed into good products during the process. Therefore, a punching machine is used for punching mark identification. Due to the high density of circuit wiring on the FPC board, the punching position requires high precision. However, when punching and marking, it is easily affected by various external factors, such as light, which makes the mark position unclear and easily leads to mark position errors. Summary of the invention

[0004] In order to improve the above problems, the present application provides an FPC punching machine.

[0005] The FPC punching machine provided in this application adopts the following technical solution:

[0006] An FPC punching machine comprises a punching component, a carrying plate, a camera component and a display component; the carrying plate provides a support for an FPC board; the punching component is installed on the carrying plate; the camera component is connected to the punching end of the punching component, the camera component is provided with a shooting end for providing image shooting, and the shooting point of the shooting end and the punching point of the punching end are intersection points; the display component is connected to one end of the punching component, and the camera component is electrically connected to the display component, and the display component displays the image on the FPC board shot by the shooting end.

[0007] By adopting the above technical solution, the FPC board is placed on the carrier plate, and the image of the FPC board is recorded and transmitted to the display unit by the shooting end of the camera, and the punching position of the FPC board is magnified and imaged by the display unit. Then, the position of the FPC board is adjusted along the carrier plate to perform position positioning. When a defective product is found, the FPC board is stopped from moving to freeze the image at the required punching position. The punching end of the punching unit is inserted into the FPC board to mark the holes to prevent them from being mixed into the good product area during the process, thereby improving the accuracy of positioning and punching.

[0008] Optionally, the camera element is provided with a fill light unit, and a fill light point of the fill light unit intersects with a shooting point of the shooting end.

[0009] By adopting the above technical solution, the light irradiation direction of the fill light part is consistent with the shooting direction, so that the fill light part provides a fill light effect for the shooting end, thereby improving the accuracy of light source focusing and ensuring that the shooting pattern of the shooting end is clear.

[0010] Optionally, a shading member is provided at one end of the punching member away from the display member.

[0011] By adopting the above technical solution, the shading element can block the light except the light from the fill light part at the shooting end, thereby reducing the interference of other light on the shooting end, further ensuring the clarity of the pattern photographed by the shooting end, and indirectly improving the accuracy effect.

[0012] Optionally, the shading member includes an annular shading portion, and the shooting end is located above the annular shading portion.

[0013] By adopting the above technical solution, the annular shading part blocks the light around the shooting end, and utilizes its annular characteristics to block all the illumination light around the shooting end except the fill light part that interferes with the shooting accuracy, thereby further ensuring the clarity of the pattern shot by the shooting end.

[0014] Optionally, the annular shading portion is slidably connected to the punching piece, and the shading piece also includes an elastic portion; the punching end is located above the annular shading portion, and the punching end is provided with a first wedge-shaped surface; the annular shading portion and the punching end are provided with a second wedge-shaped surface in a direction opposite to the punching end, and the first wedge-shaped surface is in contact with the second wedge-shaped surface; one end of the elastic portion is connected to the annular shading portion, and the other end is connected to the punching piece.

[0015] By adopting the above technical solution and utilizing the pushing characteristics of the first wedge surface and the second wedge surface, the punching end will not be affected by the annular shading portion and the punching path will not be blocked, while the shading effect of the annular shading portion is ensured. At the same time, the reset action of the elastic portion can be used to reset the pushed annular shading portion, thereby ensuring stable shading of the annular shading portion.

[0016] Optionally, a hidden groove is provided on the punching member, and the elastic part is located in the hidden groove.

[0017] By adopting the above technical solution, the elastic part can be limited by the hidden groove to prevent the elastic part from bending when being compressed and affecting the reset effect.

[0018] Optionally, the annular shading portion is slidably connected to the punching member, and the shading member further includes a driving portion; the driving portion is installed on the punching member away from the punching end and is electrically connected to the punching member, and the driving end is connected to the annular shading portion.

[0019] By adopting the above technical solution, the punching part and the driving end can operate synchronously, providing movement of the punching end and the annular shading part, so that the movement positions of the punching end and the annular shading part are staggered. This method has a more automated effect and does not require the punching end to contact the annular shading part, making the punching position accuracy of the punching end more precise and reducing the occurrence of errors.

[0020] Optionally, an anti-sticking portion is provided at one end of the annular shading portion close to the supporting plate.

[0021] By adopting the above technical solution, the punching end will rise after punching, which may easily cause the FPC board to stick to the punching end and rise synchronously, affecting the subsequent defective product detection. The anti-sticking column can be used to get close to the FPC board, so that the FPC board cannot rise with the punching end, thereby ensuring the stability of the FPC board's punching.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The FPC board is placed on the carrier board, and the image of the FPC board is recorded and transmitted to the display unit by the shooting end of the camera. The punching position of the FPC board is magnified by the display unit, and then the position of the FPC board along the carrier board is adjusted to locate the position. When a defective product is found, the FPC board is stopped from moving, and the image is fixed at the position where the hole is required. The punching end of the punching unit is inserted into the FPC board for punching marks to prevent it from being mixed into the good product area during the process, thereby improving the accuracy of positioning and punching.

[0024] 2. The light irradiation direction of the fill light unit is consistent with the shooting direction, so that the fill light unit provides fill light effect for the shooting end, thereby improving the accuracy of light source focus and ensuring clear shooting patterns at the shooting end;

[0025] 3. The light shielding piece can shield the light except the light from the fill light part, thereby reducing the interference of other light on the shooting end, further ensuring the clarity of the pattern shot by the shooting end, and indirectly improving the accuracy effect;

[0026] 4. By utilizing the pushing characteristics of the first wedge-shaped surface and the second wedge-shaped surface, the punching end will not be affected by the annular shading part and the punching path will not be blocked, while the shading effect of the annular shading part is guaranteed. At the same time, the reset effect of the elastic part can be used to reset the pushed annular shading part to ensure stable shading of the annular shading part. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is a detailed description of the embodiments of the present application with reference to the accompanying drawings so that those skilled in the art can easily implement the present application. The present application can be embodied in a variety of different forms and is not limited to the embodiments described herein.

[0035] In the representations of the present application, the representations with reference to the terms "one embodiment", "some embodiments", "examples", "specific examples", or "some examples" etc. mean that the specific features, structures, materials or characteristics represented in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

In addition, those skilled in the art may combine and combine the different embodiments or examples represented in the present application and the features of the different embodiments or examples, unless they contradict each other.

[0036] In addition, the terms "first" and "second" are only used to indicate the target, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the representation of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] Throughout the specification, when a device is said to be "connected" to another device, this includes not only the case of "direct connection" but also the case of "indirect connection" by placing other elements therebetween. In addition, when a device is said to "include" a certain component, unless otherwise stated, it does not exclude other components, but means that other components may be included.

[0038] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0039] The embodiment of the present application discloses an FPC punching machine.

[0040] A FPC punching machine, reference Figure 1 As shown, it includes a camera component 3, a display component 4, a carrier plate 2 and a punching component 1; the carrier plate 2 provides support for the FPC board, and a plurality of extension holes are opened on the surface of the carrier plate 2 to provide a penetration effect when the punching component 1 punches holes, thereby ensuring the accuracy of the punching.

[0041] The punching member 1 is installed on the top surface of the supporting plate 2. The punching member 1 may include a driving source and a punching needle. The driving source may be a telescopic cylinder or an air cylinder. The punching needle is connected to the telescopic end of the telescopic cylinder or the air cylinder, so that the punching needle can punch the FPC board on the supporting plate 2 by the driving effect of the driving source. Therefore, the punching end 11 can be a punching needle.

[0042] The camera element 3 is connected to the punching end 11 of the punching element 1. The camera element 3 is provided with a shooting end for providing image shooting, and the shooting point of the shooting end and the punching point of the punching end 11 are the same intersection point. The camera element 3 adopts a camera or a camera, and the shooting end of the camera element 3 can record the pattern of the shooting direction.

[0043] The display component 4 is connected to one end of the punching component 1, and the camera component 3 is electrically connected to the display component 4. The display component 4 displays the image on the FPC board captured by the camera component 3. The display component 4 can be a display screen, which can receive the image pattern captured by the camera component 3 and enlarge it to the display screen.

[0044] Specifically, the FPC board is placed on the carrier plate 2, and the image of the FPC board is recorded and transmitted to the display part 4 by the shooting end of the camera 3. The punching position of the FPC board is magnified and imaged by the display part 4. Then, the position of the FPC board is adjusted along the carrier plate 2 to perform position positioning. When a defective product is found, the movement of the FPC board is stopped to freeze the image at the required punching position. The punching end 11 of the punching part 1 is inserted into the FPC board for punching marking to prevent it from being mixed into the good product area during the process, thereby improving the accuracy of positioning and punching.

[0045] The shooting end is tilted so that the shooting direction can be aligned with the punching position and staggered with the punching end 11 to avoid interference with the punching end 11 during punching.

[0046] In some embodiments, reference Figure 2 As shown, a shading member 5 is provided at one end of the punching member 1 away from the display member 4, and the shading member 5 blocks other light rays. The shading member 5 can be a shading plate, and the shading plate can block other light rays at the shooting end, thereby reducing the interference of other light rays on the shooting end, further ensuring the clarity of the pattern shot by the shooting end, and indirectly improving the accuracy effect.

[0047] Furthermore, the shading member 5 includes an annular shading portion 51, and the shooting end is located above the annular shading portion 51 to block the illumination path of other light. The annular shading portion 51 can adopt an annular shading frame, that is, a rectangular frame structure, which is hollow inside. The shooting direction of the shooting end passes through the hollow portion of the annular shading portion 51, so that the punching position of the punching end 11 can be photographed. At the same time, since the shooting end is located above the annular shading portion 51, the annular shading portion 51 can block the light around the shooting end, that is, using its annular characteristics, all illumination light around the shooting end except the fill light portion 31 that interferes with the shooting accuracy is blocked, thereby further ensuring the clarity of the pattern shot by the shooting end.

[0048] Further, refer to Figure 3 and Figure 4 As shown, the annular shading portion 51 is slidably connected to the punching member 1, so that the annular shading portion 51 can slide along the surface of the punching member 1 without falling off, the shading member 5 also includes an elastic portion 52, the elastic portion 52 can be a spring, the spring can be made of metal or plastic material, the punching end 11 is located above the annular shading portion 51, and the punching end 11 is provided with a first wedge-shaped surface 111, that is, a side surface of the punching end 11 close to the annular shading portion 51 is the first wedge-shaped surface 111.

[0049] A second wedge-shaped surface 511 is provided on the annular shading portion 51 in a direction opposite to the punching end 11. When the punching end 11 descends to punch a hole in the FPC board, the first wedge-shaped surface 111 contacts the second wedge-shaped surface 511. At the same time, as the punching end 11 continues to descend, the first wedge-shaped surface 111 presses down the second wedge-shaped surface 511, so that after the second wedge-shaped surface 511 is pressed, the entire annular shading portion 51 slides along the punching member 1 to the side away from the punching end 11.

[0050] At the same time, one end of the elastic part 52 is connected to the annular shading part 51, and the other end is connected to the punching member 1, so that when the annular shading part 51 slides along the punching member 1 toward the side away from the punching end 11, it can squeeze the elastic part 52, and the elastic part 52 is squeezed to generate elastic force to reset the annular shading part 51.

[0051] Specifically, when the punching end 11 punches a hole in the FPC board, the punching end 11 moves toward the FPC board, and at the same time, the first wedge surface 111 contacts the second wedge surface 511 and pushes the annular shading portion 51. The annular shading portion 51 slides along the punching member 1 and squeezes the elastic portion 52. When the punching end 11 completes the punching, the punching end 11 rises and detaches from the FPC board, so that the first wedge surface 111 and the second wedge surface 511 are separated. After the second wedge surface 511 loses the pressing effect of the first wedge surface 111, it is reset by the elastic force of the elastic portion 52 and restored to the position below the punching end 11. By utilizing the pushing characteristics of the first wedge surface 111 and the second wedge surface 511, the punching end 11 will not be affected by the annular shading portion 51 and the punching path will not be blocked, thereby ensuring the shading effect of the annular shading portion 51. At the same time, the reset effect of the elastic portion 52 can be used to reset the pushed annular shading portion 51 to ensure stable shading of the annular shading portion 51.

[0052] Among them, reference Figure 3 As shown, a hidden groove 12 is provided on the punching member 1, and the elastic part 52 is located in the hidden groove 12. The inner diameter of the hidden groove 12 matches the outer diameter of the elastic part 52, so that the elastic part 52 is stably located in the hidden groove 12. When the elastic part 52 adopts a spring, the spring is easily bent to both sides under pressure, affecting the elastic effect of reset. Therefore, the elastic part 52 can use the hidden groove 12 to limit the elastic part 52 to avoid bending of the elastic part 52 when it is compressed and affecting the reset effect.

[0053] Among them, a telescopic rod is provided on the annular shading portion 51, the telescopic rod is plugged into the hidden groove 12, and a protrusion is provided on the telescopic rod. The telescopic rod is inserted into the elastic portion 52, and the protrusion is used to abut against the elastic portion 52 to press the elastic portion 52, so that when the annular shading portion 51 moves along the punching member 1, the telescopic rod moves along the hidden groove 12, which will not limit the sliding of the annular shading portion 51, and at the same time stably squeeze the elastic portion 52.

[0054] In some embodiments, reference Figure 4 As shown, the camera 3 is provided with a fill light part 31, and the fill light direction of the fill light part 31 is consistent with the shooting direction of the shooting end. The fill light part 31 can use a fill light lamp, which can be specifically an LED fill light lamp. The light irradiation direction of the fill light part 31 is consistent with the shooting direction, and the fill light point of the fill light part 31 intersects with the shooting point of the shooting end, so that the fill light part 31 provides a fill light effect for the shooting end, thereby improving the accuracy of the light source focus, ensuring that the shooting pattern of the shooting end is clear, and making the punching position more accurate.

[0055] In another embodiment, reference Figure 5 As shown, the annular shading portion 51 is slidably connected to the punching member 1, and the shading member 5 also includes a driving portion 53, which is installed on the punching member 1 away from the punching end 11. The driving portion 53 can adopt a driving element with a telescopic effect such as a telescopic cylinder or a cylinder, and the driving portion 53 is electrically connected to the punching member 1.

[0056] The driving end of the driving part 53 is the telescopic end, and the driving end is connected to the annular light shielding part 51 , so that the annular light shielding part 51 can slide along the surface of the punching member 1 under the driving end of the driving part 53 .

[0057] Specifically, when the punching end 11 descends to the FPC board to punch a hole, the punching member 1 sends an electrical signal to the driving portion 53, and the driving end of the driving portion 53 synchronously drives the annular shading portion 51 to slide along the surface of the punching member 1, thereby staggering the punching path of the punching end 11. When the punching end 11 completes punching and rises, an electrical signal is sent to the driving portion 53, and the driving end synchronously drives the annular shading portion 51 to slide along the punching member 1 and return to the bottom of the punching end 11. This method can synchronously provide movement of the punching end 11 and the annular shading portion 51. Compared with the method of using the elastic portion 52, this method has a more automated effect, and there is no need for the punching end 11 to contact the annular shading portion 51, so that the punching position accuracy of the punching end 11 is finer, reducing the occurrence of errors.

[0058] In some embodiments, reference Figure 5 As shown, the annular shading portion 51 is provided with an anti-sticking portion 54 near one end of the carrier plate 2. The anti-sticking portion 54 can be an anti-sticking column. The anti-sticking column is located at the bottom of the annular shading portion 51, that is, near one end of the carrier plate 2. The main function of the anti-sticking column is that when the punching end 11 descends to punch the FPC board, the punching end 11 will rise after punching, which can easily make the FPC board stick to the punching end 11 and rise synchronously, affecting the subsequent defective product detection. Therefore, the anti-sticking column can be used to get close to the FPC board, so that the FPC board cannot rise with the punching end 11, thereby ensuring the stability of the punching of the FPC board.

[0059] Among them, the anti-sticking part 54 can also be provided with a rebound compression spring, and a telescopic opening is opened on the annular shading part 51. The anti-sticking part 54 can move along the telescopic opening toward the carrier plate 2 or toward the punching end 11, and the rebound compression spring is connected to the end of the anti-sticking part 54 close to the punching end 11, and provides a rebound elastic force, so that when the FPC board contacts the anti-sticking part 54, the anti-sticking part 54 is affected by the FPC part to squeeze the rebound compression spring, and the rebound compression spring generates an elastic force to push the anti-sticking part 54 toward the carrier plate 2, so that the FPC board is quickly pushed back onto the carrier plate 2 by the anti-sticking part 54. The rebound compression spring can reduce the rigid contact between the anti-sticking part 54 and the FPC board, provide a certain buffering effect, and avoid the anti-sticking part 54 directly and rigidly contacting the FPC board, resulting in scratches on the FPC board.

[0060] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
