Description

Technical Field

[0001] The invention relates to the field of flexible printed circuit board (FPC) manufacturing equipment, in particular to a flexible FPC bearing platform with multiple strips and a strip suspended bearing shaping mechanism thereof. Background Art

[0002] Flexible circuit boards, also known as "FPC soft boards", are printed circuit boards made of flexible insulating substrates. FPC can provide excellent electrical performance, meet the needs of smaller and higher density installation designs, and also help reduce assembly processes and enhance reliability. Flexible circuit boards FPC soft boards can be bent, wound, and folded freely, and can withstand millions of dynamic bends without damaging the wires. They 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; and can greatly reduce the size and weight of electronic products, which is suitable for the development of electronic products towards high density, miniaturization, and high reliability.

[0003] Flexible FPC generally includes a main belt body and multiple branch belts connected to the main belt body. In the actual manufacturing process, the branch belts of the flexible FPC need to undergo multiple processing procedures, which requires the flexible FPC to be placed flat on the platform as a whole and maintain its surface flatness consistency. For the flexible FPC used in the main control platform of new energy vehicles, its length can reach 1-2m. When carrying the flexible FPC, its length affects the difficulty of controlling its flatness accuracy. For example, in order to ensure the position stability of the flexible FPC on the platform, multiple vacuum nozzles are usually used to fix the flexible FPC with negative pressure adsorption force. The defect is that due to the difference in adsorption force of different nozzles, the local deformation of the flexible FPC is different, thereby affecting its overall flatness, especially for the flexible FPC with multiple branch belts, the flatness change difference is greater. In addition, the branch belts of the flexible FPC need to undergo processing techniques such as bending in subsequent processes, requiring the branch belts to be suspended. For the suspended branch belts, due to the influence of their own gravity, they will bend and other situations, affecting the subsequent processing accuracy. Summary of the invention

[0018] The beneficial effects of the present invention are: In view of the defects and shortcomings of the prior art, the present invention independently developed and designed a flexible FPC bearing platform with built-in interconnected strip air grooves as the overall air supply structure, which ensures the consistency of suction of multiple nozzles and effectively reduces the surface flatness differences of the FPC belt body caused by local suction differences. At the same time, it has the functions of synchronous bearing and surface shaping of suspended branch belts, effectively ensuring the surface flatness and improving the positioning accuracy of the multi-branch flexible FPC bearing platform and its branch belt suspended bearing shaping mechanism.

[0019] The present invention aims to design an automatic carrying platform for a flexible FPC with multiple strips, which can horizontally carry the flexible FPC and drive it to automatically move between various processing stations during the actual production process, so as to facilitate different production and processing. The present invention also has highly uniform automatic adsorption and fixation and linkage clamping functions, and realizes the carrying and shaping of the strips in a suspended state, so as to greatly improve the surface flatness and ensure the position accuracy of the subsequent processing of the flexible FPC. Specifically, the present invention adopts a support seat and a base arranged at intervals in the upper and lower parts to form an integral seat body, and a plurality of air grooves are provided on the lower base according to the belt structure and number of the flexible FPC, and the plurality of air grooves are interconnected. In actual use, the air holes provided on the side walls of the air grooves and the air nozzles inserted in the air holes are connected to an external vacuum generator, and a vacuum negative pressure is generated in the plurality of air grooves by the vacuum generator. Since the plurality of air grooves are interconnected, the vacuum negative pressure inside the plurality of air grooves is the same under the premise of being connected to the same vacuum generator, and a plurality of suction nozzle grooves are provided on the tops of the plurality of air grooves respectively, and the plurality of suction nozzle grooves are arranged at intervals along the direction of the air grooves, and suction nozzles are correspondingly inserted in the suction nozzle grooves, and the suction nozzles pass through the support seat to generate a vacuum negative pressure on the surface of the support seat so as to downwardly adsorb and fix the flexible FPC thereon; through the above interconnected air groove structure, the consistency of the vacuum negative pressure adsorption force of the plurality of suction nozzles on the flexible FPC is effectively guaranteed, the deformation difference of the belt surface caused by the local suction force difference is reduced, and the surface flatness of the flexible FPC during the adsorption process is improved.

[0020] In addition, based on the process requirement that the flexible FPC needs to be suspended in the actual production process, the present invention horizontally supports the suspended second branch belt through a movable bearing and shaping mechanism, and realizes shaping the surface of the second branch belt during the movement toward the bottom of the second branch belt, effectively avoiding the local bending deformation caused by its own gravity, improving the surface flatness, and ensuring the position accuracy of the belt body during the subsequent processing. Specifically, the bearing and shaping mechanism of the present invention realizes the movable bearing of the suspended second branch belt, that is, when the second branch belt is before the subsequent processing procedure or when the following platform is transferred between different stations, it can be supported by the bearing and shaping mechanism. When the subsequent process needs to be processed, such as when the second branch belt needs to be fixed from the bottom and driven to rotate and bend during the bending action, the bearing and shaping mechanism is retracted from the bottom of the second branch belt in advance to leave the action space of the subsequent bending mechanism; at the same time, when the bearing and shaping mechanism moves toward the direction of the second branch belt and carries it, it also synchronously completes the shaping of its surface, effectively ensuring its surface flatness, which plays an important role in improving the position accuracy during the subsequent bending. Specifically, the bearing and shaping mechanism of the present invention uses a bearing U-seated seat with a push groove H on the side as a bearing execution structure. The bearing U-seated seat approaches or moves away from the second support belt under the horizontal thrust of the bearing cylinder. The top surface of the bearing U-seated seat is a bearing plane, on which suction holes are arranged, which are used to vacuum adsorb and fix the second support belt downward during the bearing process; during the movement of the bearing U-seated seat toward the second support belt, the transmission rod inserted in it is driven to move through the push groove, and the transmission rod drives the shaping block connected to the top thereof to move; in a natural state, the shaping block slidably arranged on the seat body is connected to the seat body through a spring, and the elastic force of the spring makes the shaping seat tend to move in the direction away from the second support belt, and at this time, the transmission rod is not close to the groove wall in the push groove; when the bearing U-seated seat moves toward the second support belt, the push groove The groove wall gradually comes close to the transmission rod. At this time, the bearing U seat moves to the bottom of the shaping block, and a shaping groove is formed between the two. The side of the shaping groove close to the second branch belt is an open structure, and a guiding inclined surface is provided at the opening, so that the opening is a trumpet-shaped structure, so as to better insert the second branch belt; when the bearing U seat continues to move toward the second branch belt, the shaping block is driven to move synchronously by the transmission rod, that is, the second branch belt is relatively gradually entered into the shaping groove while maintaining the shaping groove unchanged. In this process, the surface shaping of the second branch belt is completed through the upper and lower groove walls of the shaping groove; when subsequent processes need to be processed at the second branch belt, the bearing U seat moves away from the second branch belt, and the shaping block retreats using the spring force when the force of the bearing U seat is reduced to less than the spring force.

[0021] In addition, based on the process requirements that the platform drives the flexible FPC to move between various workstations or the platform needs to drive the flexible FPC to rotate as a whole later, in order to ensure the position stability of the flexible FPC on the platform, the present invention is also provided with a clamping mechanism for clamping the flexible FPC from above; the special feature is that the clamping mechanism of the present invention adopts a rotating clamping method above the flexible FPC belt body, which can effectively avoid motion interference in the process of taking and placing the flexible FPC, compared with the clamping method of lifting and lowering in the vertical direction, that is, in the process of taking and placing the flexible FPC, the clamping mechanism is flipped outward and upward to reserve the space above the platform. After C is taken and placed, it is flipped inwards and pressed from above; further, since the rotational pressing action of the pressing mechanism of the present invention only needs to be performed within a 90° angle range, the use of a cylinder instead of the traditional rotary power to provide a carrier motor can effectively reduce the driving cost, and the linear power output by the pressing cylinder in the vertical direction is connected through the meshing of the rack and the gear on the lifting rod, which converts the linear power into rotational power to realize the rotational drive of the gear. The gear drives the rotating rod and the pressure block to rotate to complete the pressing or loosening action. This tooth meshing connection method between the lifting rod and the gear can achieve precise control of the rotation angle by controlling the tooth pitch. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The present invention designs a structure that uses built-in interconnected strip air grooves as an overall air supply structure, which ensures the consistency of suction of multiple nozzles, effectively reduces the difference in surface flatness of the FPC belt body caused by local suction difference, and at the same time has the synchronous bearing and surface shaping of the suspended branch belt, effectively ensures its surface flatness, and improves the position accuracy of a flexible FPC bearing platform with multiple branches and its branch belt suspended bearing and shaping mechanism. The present invention aims to design an automatic bearing platform for a flexible FPC with multiple branches, which can horizontally bear the flexible FPC and drive it to automatically operate between various processing stations during the actual production process, so as to facilitate different production and processing; the present invention also has the functions of automatic adsorption and fixation with high uniformity and linkage clamping, and realizes the bearing and shaping of the branch belt in a suspended state, so as to greatly improve its surface flatness and ensure the position accuracy of subsequent processing of the flexible FPC.

In actual use, the air holes provided on the side walls of the air grooves and the air nozzles inserted in the air holes are connected to an external vacuum generator, and a vacuum negative pressure is generated in the plurality of air grooves by the vacuum generator. Since the plurality of air grooves are interconnected, the vacuum negative pressure inside the plurality of air grooves is the same under the premise of being connected to the same vacuum generator, and a plurality of suction nozzle grooves are provided on the tops of the plurality of air grooves respectively, and the plurality of suction nozzle grooves are arranged at intervals along the direction of the air grooves, and suction nozzles are correspondingly inserted in the suction nozzle grooves, and the suction nozzles pass through the support seat to generate a vacuum negative pressure on the surface of the support seat so as to downwardly adsorb and fix the flexible FPC thereon; through the above interconnected air groove structure, the consistency of the vacuum negative pressure adsorption force of the plurality of suction nozzles on the flexible FPC is effectively guaranteed, the deformation difference of the belt surface caused by the local suction force difference is reduced, and the surface flatness of the flexible FPC during the adsorption process is improved.

Example 2

[0053] like Figure 11 to Figure 12 As shown, as an embodiment of the present invention, this embodiment discloses another clamping mechanism 3. The clamping mechanism 3 of this embodiment is different from the clamping mechanism 3 of Example 1 in that the shape structure of the clamping block 39 is replaced to perform clamping on different local positions of the flexible FPC belt body. Example 3

[0054] like Figures 13 to 15As shown, as an embodiment of the present invention, this embodiment discloses a suspended bearing shaping mechanism of a flexible FPC bearing platform with multiple branches, including a bearing component and a shaping component, wherein the bearing component is arranged on the side of the seat body, and outputs linear motion along the side direction of the seat body; the shaping component is arranged on the seat body, and is slidably connected to the seat body through a slide rail arranged along the side direction of the seat body, and a shaping groove J is formed between the shaping component and the bearing component; one end of the shaping component extends into the bearing component, and follows the linear motion of the bearing component, so that the shaping groove J is inserted into the suspended second branch belt 03 from the upper and lower sides, and the surface of the second branch belt 03 is shaped during the linear motion of the shaping groove J.

[0055] The bearing assembly includes a mounting seat 41, a bearing cylinder 42 and a bearing U seat 43, wherein the mounting seat 41 is fixedly arranged on the seat body and forms a vertical supporting plane on the outer side of the seat body; the bearing cylinder 42 is arranged on the vertical supporting plane of the mounting seat 41, and the output end is arranged in a direction parallel to the side of the seat body; the bearing U seat 43 is connected to the output end of the bearing cylinder 42, and a push groove H is opened in the bearing U seat 43; the top and one side of the push groove H are open surfaces; the top surface of the bearing U seat 43 is a bearing plane, on which a suction hole 44 is arranged, and the suction hole 44 is connected to the air path set inside the bearing U seat 43; a second air hole 45 is provided on the side wall of the bearing U seat 43, the inner end of the second air hole 45 is connected to the air path, and the outer end is inserted with an air path connector for connecting an external vacuum generator to generate a vacuum negative pressure at the suction hole 44.

[0056] The shaping assembly includes a transmission rod 46 and a shaping block 47, wherein the shaping block 47 is slidably connected to the surface of the seat body and is connected to the protruding block arranged on the surface of the seat body through a horizontally arranged spring. In the natural state, the tension of the spring pulls the shaping block 47 to move in the opposite direction of the output power of the bearing cylinder 42; the bottom surface height of the shaping block 47 is higher than the top surface height of the bearing U seat 43; the transmission rod 46 is fixedly connected to the bottom of the shaping block 47 and extends vertically downward into the push groove H; the bearing U seat 43 moves toward the second support belt 03 until the inner wall of the push groove H abuts against the transmission rod 46, and a shaping groove J is formed between the shaping block 47 and the bearing U seat 43, and the bearing U seat 43 continues to move linearly toward the second support belt 03, and drives the shaping block 47 to overcome the elastic force of the spring through the transmission rod 46 to move synchronously until the shaping groove J is inserted into the second support belt 03, and completes the surface shaping of the second support belt 03 during the linear motion.

[0057] The bearing and shaping mechanism of the present invention realizes the movable bearing of the second branch belt 03 placed in the air, that is, the second branch belt 03 can be supported by the bearing and shaping mechanism before the subsequent processing steps or when following the platform to transfer between different workstations. When the subsequent processing steps need to be processed, such as when it is necessary to adsorb and fix the second branch belt 03 from the bottom and then drive the second branch belt 03 to rotate and bend during the bending action, the bearing and shaping mechanism 4 is retracted from the bottom of the second branch belt 03 in advance to leave room for the subsequent bending mechanism to move. At the same time, the bearing and shaping mechanism 4 moves toward the second branch belt 03, and in the process of bearing it, it also synchronously completes the shaping of its surface, effectively ensuring its surface flatness, which plays an important role in improving the position accuracy during subsequent bending. Specifically, the bearing and shaping mechanism of the present invention uses a bearing U seat 43 with a push groove H on the side as a bearing execution structure. The bearing U seat 43 approaches or moves away from the second support belt 03 under the horizontal thrust of the bearing cylinder 42. The top surface of the bearing U seat 43 is a bearing plane, on which suction holes are arranged, which are used to vacuum adsorb and fix the second support belt 03 downward during the bearing process; when the bearing U seat 43 moves toward the second support belt 03, the push groove H drives the transmission rod 46 inserted therein to move, and the transmission rod 46 drives the shaping block 47 connected to the top thereof to move; in a natural state, the shaping block 47 slidably arranged on the seat body is connected to the seat body through a spring, and the elastic force of the spring makes the shaping seat 47 tend to move in the direction away from the second support belt 03, and at this time the transmission rod 46 is not close to the groove wall in the push groove H; when the bearing U seat 43 moves toward the second support belt 03, the push groove H The groove wall gradually comes close to the transmission rod 46. At this time, the bearing U seat 43 moves to the bottom of the shaping block 47, and a shaping groove J is formed between the two. The side of the shaping groove J close to the second branch belt 03 is an open structure, and a guiding inclined surface K is provided at the opening, so that the opening is a trumpet-shaped structure, so as to better insert the second branch belt 03; when the bearing U seat 43 continues to move toward the second branch belt 03, the shaping block 47 is driven to move synchronously by the transmission rod 36, that is, the second branch belt 03 is relatively gradually entered into the shaping groove J while maintaining the shaping groove J unchanged. In this process, the surface shaping of the second branch belt 03 is completed by the upper and lower groove walls of the shaping groove J; when the subsequent process needs to be processed at the second branch belt 03, the bearing U seat 43 moves in the direction away from the second branch belt 03, and the shaping block 47 retreats by the spring force when the force acting on the bearing U seat 43 is reduced to less than the spring force.
