Description

Technical Field

[0001] The invention relates to the technical field of flexible circuit board processing, and in particular to an automatic connection mechanism for a flexible circuit board. Background Art

[0002] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical properties, can meet the design needs of smaller and higher density installations, and also help reduce assembly processes and enhance reliability. Flexible circuit boards can be bent, wound, and folded freely, can withstand millions of dynamic bends without damaging the wires, can be arranged arbitrarily according to spatial layout requirements, and can be moved and stretched arbitrarily in three-dimensional space, thereby achieving the integration of component assembly and wire connection.

[0003] When the flexible circuit board coil is being rolled, since the existing flexible circuit board processing line does not have the function of automatic connection, workers need to wait for a long time for the processed flexible circuit board coil to be rolled up, and then manually connect the unprocessed flexible circuit board coil to the processed coil. This operation is not only time-consuming and labor-intensive, seriously affecting the processing efficiency of the flexible circuit board, but also the manual connection operation easily leads to difficulty in aligning the front and rear batches of coils, and the connection accuracy of the flexible circuit board coil is not high, which seriously affects the quality of the final product. Summary of the invention

[0004] The present invention discloses an automatic connection mechanism for flexible circuit boards, which solves the problem that in the traditional processing of flexible circuit boards, the connection operation is not only time-consuming and labor-intensive, seriously affecting the processing efficiency of the flexible circuit boards, but also easily leads to difficulty in aligning the front and rear batches of coils, and the connection accuracy of the flexible circuit board coils is not high, which seriously affects the quality of the final product.

[0005] In order to solve the above technical problems, the present invention specifically adopts the following technical solutions:

[0006] A flexible circuit board automatic connection mechanism comprises a frame assembly, on which a material preparation mechanism, a material clamping mechanism and a cutting mechanism are arranged in sequence in the horizontal direction; the material preparation mechanism comprises a material preparation mechanism for fixing an unprocessed flexible circuit board coil and waiting for connection, and a material preparation driving mechanism for driving the material preparation mechanism to approach or move away from the cutting mechanism; the material clamping mechanism comprises a material clamping mechanism for clamping and fixing the tail of the processed flexible circuit board coil, and a material clamping driving mechanism for driving the material clamping mechanism to move, so that the material clamping mechanism will not hinder the material preparation after its own work is completed The clamping mechanism is provided with a photoelectric detection mechanism located below the clamping assembly and used to detect the rolling state of the processed flexible circuit board coil; the cutting mechanism includes a cutting assembly used to cut and fix the tail of the processed flexible circuit board coil and align it with the unprocessed flexible circuit board coil, and a cutting drive assembly used to drive the cutting assembly to move in the vertical and horizontal directions; the cutting mechanism is provided with a pressing mechanism located above the cutting assembly and used to press and fix the joints of the front and rear batches of flexible circuit board coils.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] The flexible circuit board coil is transported by an external conveying device and the processed coil is passed through the cutting component, the clamping component and the photoelectric detection mechanism from high to low in sequence. During the transportation process, the staff fixes the unprocessed coil on the preparation component in advance and sticks tape on the surface of the unprocessed coil to complete the preparation work before the connection. When the photoelectric detection mechanism detects that the processed coil is finished, since the photoelectric detection mechanism is arranged under the clamping component, the clamping component can be used to clamp and fix the tail of the processed coil. At this time, the external conveying device also suspends the transportation of the processed coil; the cutting drive component is used to adjust the height of the cutting component and make it aligned with the preparation component After alignment, the cutting drive assembly is used to drive the cutting assembly to move in the horizontal direction and make it fit with the tail of the processed coil, and then the cutting assembly is used to cut and fix the tail of the processed coil, at which time the clamping assembly fails to fix the tail of the processed coil; then the clamping drive assembly is used to drive the clamping assembly to move so that it will not interfere with the work of the material preparation mechanism and the cutting mechanism, and then the material preparation drive assembly is used to drive the material preparation assembly close to the cutting mechanism, so that the connection operation of the front and rear batches of flexible circuit board coils can be automatically completed. In addition, the pressing mechanism can be used to further press and fix the connection, which effectively improves the connection quality. The present invention has a high degree of automation. By setting a photoelectric detection mechanism, a material preparation mechanism, a clamping mechanism and a cutting mechanism, the preparation, clamping, cutting, alignment and connection operations of the front and rear batches of flexible circuit board coils can be automatically completed, which greatly improves the connection accuracy and the processing efficiency of the flexible circuit board. In addition, a pressing mechanism is also provided to further press and fix the connection, which effectively improves the connection quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1 and Figure 2As shown, the material preparation assembly includes a material preparation base plate 21 which is fixed on the frame assembly 1 and is horizontal. A horizontal slide 23 is movably provided above the material preparation base plate 21. One end of the slide 23 close to the cutting mechanism 4 is rotatably connected to a material preparation suction cup seat 26. The side of the material preparation suction cup seat 26 facing away from the slide 23 is arc-shaped, and the arc-shaped concave surface is arranged toward the slide 23. The top surface of the material preparation suction cup seat 26 is connected to a straight material preparation suction cup 27, and also includes a rotating cylinder 28 for driving the material preparation suction cup seat 26 to rotate. The rotating cylinder 28 enables the material preparation suction cup 27 to rotate ninety degrees from the top surface of the material preparation suction cup seat 26 to the side of the material preparation suction cup seat 26 close to the cutting mechanism 4, and the arc surface of the material preparation suction cup seat 26 rotates to the bottom surface of the material preparation suction cup seat 26 accordingly. Specifically, side panels 241 are fixed at both ends of the side of the material preparation fixing plate 24 facing away from the slide seat 23, and a horizontal rotating shaft 25 is rotatably connected between the two side plates 241. The material preparation suction cup seat 26 is located between the two side plates 241 and the material preparation suction cup seat 26 is connected to the rotating shaft 25. One end of the rotating shaft 25 passes through one of the side plates 241 and extends to the outside of the side plate 241. The end of the rotating shaft 25 located outside the side plate 241 is connected to the vacuum head 271, and the output end of the rotating cylinder 28 is fixedly connected to the end of the rotating shaft 25 located outside the side plate 241. During the conveying process of the processed flexible circuit board coil, the head of the unprocessed flexible circuit board coil is unfolded and made to fit with the arc-shaped surface of the preparation suction cup seat 26 in the rolling direction, and at the same time, the head of the unprocessed coil is aligned with the preparation suction cup 27 on the top surface of the preparation suction cup seat 26, and the preparation suction cup 27 is used to absorb and fix the unprocessed coil through the vacuum head 271, and the top surface of the unprocessed coil head is pasted with tape to complete the preparation work before the connection. At this time, the head of the unprocessed coil is kept horizontal. state; until the processed flexible circuit board coil is finished being rolled out and the connection operation is to be carried out, the rotating cylinder 28 is started, and the output end of the rotating cylinder 28 drives the rotating shaft 25 to rotate around its own axis, which can drive the material preparation suction cup 27 on the material preparation suction cup seat 26 to rotate, thereby driving the head of the unprocessed coil to rotate ninety degrees and be in a vertical state, and then the material preparation drive assembly is used to drive the material preparation assembly close to the cutting mechanism 4, which can drive the head of the unprocessed coil to fit with the processed coil, thereby automatically completing the connection operation.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, the material preparation drive assembly includes a material preparation linear slide 22 fixed to the top surface of the material preparation bottom plate 21 and in a horizontal state, a slide rail 221 parallel to the material preparation linear slide 22 is fixed to the top surface of the material preparation bottom plate 21, and a slider 222 fixed to the bottom surface of the slide seat 23 is sleeved on the slide rail 221. When the docking operation is to be performed, the material preparation linear slide 22 is started to control the horizontal movement of the slide seat 23, thereby controlling the horizontal movement of the unprocessed flexible circuit board coil adsorbed on the material preparation suction cup 27 to complete the docking operation; the setting of the slide rail 221 and the slider 222 can play a good role in limiting and guiding the horizontal movement of the slide seat 23.

[0028] Furthermore, if Figure 1 , Figure 2 and Figure 3 As shown, a plurality of vertical support rods 211 are fixed to the top surface of the material preparation base plate 21, a shield 29 whose inner wall is fixed to the support rods 211 is fixed to the material preparation base plate 21, and a side fixing seat 212 fixed to the frame assembly 1 is fixed to the side of the material preparation base plate 21. By providing the shield 29, the material preparation linear slide 22, the slide seat 23, the slide rail 221 and the slider 222 in the shield 29 can be better protected, and the service life of each component can be extended; the side fixing seat 212 can fix and support the entire material preparation mechanism 2.

[0029] like Figure 1 and Figure 4As shown, the clamping assembly includes a clamping fixing seat 31 fixed on the frame assembly 1, a vertical support plate 33 is movably provided on the clamping fixing seat 31, a horizontal and U-shaped clamping fixing plate 34 is provided below the support plate 33, two symmetrical clamping cylinders 35 are horizontally fixed on the top surface of the clamping fixing plate 34, and the output ends of the two clamping cylinders 35 are respectively fixed with vertical clamping plates 36 located above the U-shaped channel of the clamping fixing plate 34, and the processed flexible circuit board coil passes between the two clamping plates 36. When the tail of the processed coil needs to be fixed, the two clamping cylinders 35 simultaneously drive the corresponding clamping plates 36 to move relative to each other to achieve clamping. Specifically, a plurality of horizontal cross plates 331 are fixed at the bottom end of the support plate 33, and a plurality of vertical connecting rods 332 are fixed between the plurality of cross plates 331 and the clamping fixing plate 34. By using external conveying equipment, the processed flexible circuit board coil passes through the U-shaped channel of the clamping fixing plate 34 during the conveying process. At this time, the processed coil is conveyed between the two clamping plates 36. When the photoelectric detection mechanism detects that the processed coil is finished, the two clamping cylinders 35 are started at the same time. The two clamping cylinders 35 respectively drive the corresponding clamping plates 36 to move, thereby realizing the fixing operation of the tail of the processed coil to facilitate the subsequent cutting, alignment and connection operations; the setting of the cross plate 331 and the connecting rod 332 can not only fix and support the clamping fixing plate 34, but also make way for the clamping cylinders 35 and the clamping plates 36, and will not interfere with the conveying and clamping operations of the coil.

[0030] like Figure 1 and Figure 4 As shown, a limit bracket for limiting and guiding the processed flexible circuit board coil is movably provided above the U-shaped channel of the clamping fixing plate 34, and a limit cylinder 37 for driving the limit bracket to move horizontally is horizontally fixed on the support plate 33. Specifically, the limit bracket includes a limit plate 38 vertically fixed to the output end of the limit cylinder 37, and limit blocks 39 are respectively fixed at both ends of the side of the limit plate 38 away from the limit cylinder 37. When the flexible circuit board coil is conveyed, the flexible circuit board coil is located in the area between the limit plate 38 and the two limit blocks 39. The limit cylinder 37 controls the movement of the limit plate 38 and the two limit blocks 39 in the horizontal direction, which can limit and guide the flexible circuit board coil, and prevent the flexible circuit board coil from being offset during the conveying process and affecting the alignment accuracy during the subsequent connection.

[0031] like Figure 1 and Figure 4As shown, the material clamping drive assembly includes a material clamping linear slide 32 fixed on a material clamping fixed seat 31 and in a horizontal state, a guide rail 321 parallel to the material clamping linear slide 32 is fixed on the material clamping fixed seat 31, and a guide block 322 fixed to the support plate 33 is sleeved on the guide rail 321. When the cutting mechanism 4 completes the cutting and aligning operation of the tail of the processed flexible circuit board coil, the fixed clamping operation of the material clamping assembly on the tail of the processed coil is converted into the fixing of the tail by the cutting mechanism 4. After that, the connection operation of the front and rear batches of materials needs to be completed by the material preparation mechanism 2 and the cutting mechanism 4. The material clamping linear slide 32 drives the support plate 33 to move in the horizontal direction, so that the material clamping assembly moves out of the space between the material preparation mechanism 2 and the cutting mechanism 4 to prevent it from affecting the subsequent connection operation; the setting of the guide rail 321 and the guide block 322 can play a good role in limiting and guiding the movement of the support plate 33 in the horizontal direction.

[0032] like Figure 4 and Figure 5 As shown, the photoelectric detection mechanism includes a U-shaped photoelectric fixing plate 341 arranged parallel to the bottom of the clamping fixing plate 34. Two symmetrical photoelectric detection devices 61 are arranged under the U-shaped channel of the photoelectric fixing plate 341. The photoelectric detection device 61 is composed of an optical signal transmitter and a photosensitive sensor.

Specifically, two symmetrical photoelectric fixing seats 6 for fixing the photoelectric detection devices 61 are fixed on the bottom surface of the photoelectric fixing plate 341; a number of vertical flanges 342 are fixed between the photoelectric fixing plate 341 and the clamping fixing plate 34, the top ends of the several flanges 342 all penetrate the clamping fixing plate 34 and are fixedly connected to the bottom ends of the corresponding connecting rods 332, and the bottom surfaces of the several flanges 342 are fixed with vibration-damping blocks 343 fixed to the top surface of the photoelectric fixing plate 341; the optical signal transmitter can be a laser transmitter. An external conveying device is used to allow the processed flexible circuit board coil to pass through the U-shaped channel of the photoelectric fixing plate 341 during the conveying process. At this time, the processed coil is conveyed between the two photoelectric detection devices 61, so that the conveying status of the processed coil can be monitored by the two photoelectric detection devices 61; the setting of the vibration damping block 343 can effectively absorb and disperse the vibration generated by the clamping drive assembly in the process of driving the clamping assembly and the photoelectric detection mechanism to move, thereby extending the service life of the photoelectric detection device 61.

Specifically, the other side of the cutting suction cup seat 42 is connected to the suction head 431; a connecting block 48 is fixed to the output end of the pressure plate cylinder 47, and two cutting pressure plates 49 are respectively fixedly connected to the side of the connecting block 48 facing away from the pressure plate cylinder 47; the pressure plate cylinder 47 can be fixedly installed on the support plate 33 and is preferably arranged between the limiting cylinder 37 and the clamping cylinder 35 and the three are arranged in parallel to achieve the perfect connection between the clamping operation and the cutting and fixing operation. The height of the pressure plate cylinder 47 and the preparation suction cup seat 26 in the vertical direction is preferably set to the same height, so that the front and rear batches of coils can fit perfectly during the docking operation.After the clamping assembly has completed the operation of clamping and fixing the tail of the processed coil, the cutting drive assembly is used to adjust the height of the cutting assembly, and the opening on the cutting suction cup seat 42 and the gap between the two cutting pressure plates 49 are located at the same vertical height. The cutting drive assembly is used to drive the cutting assembly to move in the horizontal direction, and at the same time, the pressure plate cylinder 47 is started to drive the two cutting pressure plates 49 to move horizontally, so that the processed coil can be fixed between the cutting suction cup 43 and the two cutting pressure plates 49, and then the cutting linear slide 44 is used to drive the blade fixing seat 45 to move horizontally, thereby driving the cutting blade 46 to move horizontally in the opening, so as to complete the cutting and alignment operation of the processed tail of the coil, so as to ensure the alignment of the front and rear batches of coils. Alignment accuracy during docking; thereafter, the cutting suction cup 43 is used to absorb and fix the tail of the processed coil through the suction head 431, and the cutting pressure plate 49 is used to cancel the fixation of the tail, and then the clamping linear slide 32 is used to drive the support plate 33 to move out of the space between the material preparation mechanism 2 and the cutting mechanism 4, and the subsequent docking operation can be carried out; the cutting blade 46 and the blade pressure plate 461 are connected by detachable bolts, which is convenient for the staff to replace the cutting blade 46; the setting of the blade protection cover 421 can not only protect the cutting blade 46 outside the cutting suction cup seat 42, but also effectively prevent the cutting blade 46 from accidentally scratching the flexible circuit board coil when the cutting operation is not performed.

[0034] like Figure 1 , Figure 6 and Figure 7 As shown, the cutting drive assembly includes a first cutting cylinder 7 vertically fixed on the frame assembly 1, a horizontal lifting plate 71 is fixed to the output end of the first cutting cylinder 7, and a horizontal second cutting cylinder 72 is fixed to both sides of the top surface of the lifting plate 71, and a cutting fixing seat 73 fixed to the bottom surface of the cutting fixing plate 41 is fixed to the output end of the second cutting cylinder 72. When the first cutting cylinder 7 is started, the output end of the first cutting cylinder 7 can drive the lifting plate 71 to move up and down, thereby realizing the control of the height of the cutting assembly in the vertical direction; when the second cutting cylinder 72 is started, the output end of the second cutting cylinder 72 can drive the cutting fixing seat 73 to move left and right, thereby realizing the control of the position of the cutting assembly in the horizontal direction; further, a hydraulic buffer can be set on the first cutting cylinder 7, so that the first cutting cylinder 7 can be lifted and lowered smoothly, and in addition, a protective cover can be set outside the first cutting cylinder 7 and the hydraulic buffer to extend the service life of the first cutting cylinder 7.

[0035] like Figure 1 , Figure 6 and Figure 7As shown, the pressing mechanism 5 includes a pressing cylinder 51 which is horizontally fixed to the top surface of the blade fixing seat 45 and is arranged away from the cutting blade 46. The output end of the pressing cylinder 51 is fixed with a pressing fixing seat 52 located above the blade fixing seat 45. The pressing fixing seat 52 is rotatably connected to a vertical film pressing wheel 55 at one end close to the material preparation mechanism 2. Specifically, a vertical pressing connecting plate 53 is fixed to one end of the pressing fixing seat 52 close to the material preparation mechanism 2. The top and bottom ends of the pressing connecting plate 53 are respectively fixed with horizontal pressing support plates 54. The film pressing wheel 55 is rotatably arranged between the two pressing support plates 54. After the material preparation drive assembly drives the material preparation assembly close to the cutting assembly to achieve the connection between the front and rear batches of coils, the material preparation suction cup 27 maintains the adsorption and fixing function on the coil connection point and the cutting suction cup 43 is separated from the coil through the suction head 431, and the first cutting cylinder 7 is used to control the cutting assembly to move downward, and the film pressing wheel 55 and the material preparation suction cup 27 are located at the same height, and the pressing cylinder 51 is started to make the film pressing wheel 55 fit with the coil connection point.

[0036] Furthermore, if Figure 1 As shown, the frame assembly 1 includes a vertical fixed frame 11 and a fixed side plate 12 fixed to the side of the fixed frame 11 and vertical, the material preparation mechanism 2 and the material clamping mechanism 3 are fixedly mounted on the fixed side plate 12 respectively, and the cutting mechanism 4 is fixedly mounted on the fixed frame 11 and the fixed side plate 12, and a channel 13 for the cutting assembly to move is opened on the fixed side plate 12. By setting the fixed frame 11 and the fixed side plate 12, it is convenient for the staff to sequentially fix the material preparation mechanism 2, the material clamping mechanism 3 and the cutting mechanism 4 on the frame assembly 1 to ensure the smoothness of the entire connection process; in addition, it is preferred to fix an external conveying device such as a roller conveyor on the top of the fixed frame 11, and fix an external conveying device such as an unwinder on the fixed side plate 12, and the unwinder is arranged directly below the material clamping assembly (not shown in the figure), so that the flexible circuit board coil can maintain a vertical conveying state between the photoelectric detection mechanism, the material clamping assembly, and the cutting assembly, so that the entire connection process can be carried out more smoothly.

[0037] Furthermore, if Figure 2 , Figure 4 and Figure 6 As shown, the support frame 8 can be fixedly installed on the side plate 241, the support plate 33 and the cutting fixed plate 41 respectively, and at the same time, a drag chain 81 is respectively arranged between the material preparation base plate 21, the material clamping fixed seat 31 and the blade fixed seat 45 and the corresponding support frame 8.

[0039] When in use, the flexible circuit board coil is transported by an external conveying device and the processed coil is passed through the cutting assembly, the clamping assembly and the photoelectric detection mechanism from high to low in sequence. In the process of conveying the processed coil, the head of the unprocessed flexible circuit board coil is unfolded and made to fit with the arc surface of the preparation suction cup seat 26 in the rolling direction, and at the same time, the head of the unprocessed coil is aligned with the preparation suction cup 27 on the top surface of the preparation suction cup seat 26, and the preparation suction cup 27 absorbs and fixes the unprocessed coil through the air extraction head 271, and the top surface of the unprocessed coil head is pasted with tape to complete the preparation work before connection. At this time, the head of the unprocessed coil is kept in a horizontal state;

[0040] When the two photoelectric detection devices 61 detect that the processed coils are finished, the two clamping cylinders 35 are started at the same time, and the two clamping cylinders 35 respectively drive the corresponding clamping plates 36 to move, thereby realizing the fixing operation of the tail of the processed coils, and at this time, the external conveying device also stops conveying the processed coils;

[0041] Next, the height of the cutting assembly is adjusted by using the first cutting cylinder 7, and the opening on the cutting suction cup seat 42 and the gap between the two cutting pressure plates 49 are located at the same vertical height. The second cutting cylinder 72 is used to drive the cutting assembly to move in the horizontal direction, and the pressure plate cylinder 47 is started to drive the two cutting pressure plates 49 to move horizontally, so that the processed coil can be fixed between the cutting suction cup 43 and the two cutting pressure plates 49, and then the cutting linear slide 44 is used to drive the blade fixing seat 45 to move horizontally, thereby driving the cutting blade 46 to move horizontally in the opening, so as to complete the cutting and alignment operation of the processed coil tail material, so as to ensure the alignment accuracy when the front and rear batches of coil materials are connected;

[0042] After that, the cutting suction cup 43 is used to absorb and fix the tail of the processed coil through the suction head 431, and the cutting plate 49 is used to cancel the fixation of the tail by the cutting plate 49, and then the material clamping linear slide 32 is used to drive the support plate 33 to move out of the space between the material preparation mechanism 2 and the cutting mechanism 4, and the subsequent docking operation can be carried out;

[0043] When the docking operation is to be performed, the rotating cylinder 28 is started, and the output end of the rotating cylinder 28 drives the rotating shaft 25 to rotate around its own axis, which can drive the material preparation suction cup 27 on the material preparation suction cup seat 26 to rotate, thereby driving the head of the unprocessed coil to rotate at an angle of 90 degrees and to be in a vertical state, and then the material preparation linear slide 22 is used to drive the material preparation component close to the cutting component, which can drive the head of the unprocessed coil to fit with the processed coil, thereby automatically completing the docking operation;

[0044] After the connection between the front and rear batches of coils is completed, the adsorption and fixing function of the preparation suction cup 27 on the coil connection is maintained and the cutting suction cup 43 is separated from the coil through the suction head 431, and the first cutting cylinder 7 is used to control the cutting assembly to move downward, and the film pressing wheel 55 and the preparation suction cup 27 are located at the same height, and the pressing cylinder 51 is started to make the film pressing wheel 55 fit with the coil connection. At the same time, the cutting linear slide 44 is used to make the film pressing wheel 55 roll back and forth horizontally at the coil connection, so that the front and rear batches of coils can be more closely attached, effectively improving the connection quality.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
