Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and in particular to a circuit board processing production line and a use method thereof. Background Art

[0002] Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards can be called printed circuit boards or printed circuit boards. FPC circuit boards are also called flexible circuit boards. Flexible circuit boards are made of polyimide or polyester film as a substrate. They are highly reliable and extremely flexible printed circuit boards. They have the characteristics of high wiring density, light weight, thin thickness, and good bendability.

[0003] During the processing and shearing process of existing flexible circuit boards, the flexible circuit boards need to be placed horizontally on a shearing platform, and the flexible circuit boards are mostly operated by manually clamping and pulling, which causes the flexible circuit boards to fold. During shearing, the flexible circuit boards are not cut neatly, resulting in bending at the shearing point, affecting the subsequent processing of the flexible circuit boards; and when the flexible circuit boards are sheared by a shear blade, the shear blade is severely pressed down and cut and is easily damaged; and when the shear blade shears the circuit board, the conveying work of the flexible circuit board needs to be stopped, affecting the production efficiency of the circuit board. Summary of the invention

[0012] Preferably, a second screw hole is formed on the first elastic telescopic rod, and a plurality of first screw holes matching with the second screw hole are formed on the sleeve along its axial direction, and bolts are threadedly connected to the first screw hole and the second screw hole.

[0013] Preferably, the abutment plate is rotatably connected to the end of the first elastic telescopic rod via a pin shaft, and a torsion spring for driving the abutment plate to return and rotate is sleeved on the pin shaft.

[0014] Preferably, the cutting assembly includes a support plate fixed on the first elastic telescopic rod, and a second elastic telescopic rod is fixed on the support plate, wherein the telescopic end of the second elastic telescopic rod of one rotating part is connected to a cutting seat, and the telescopic end of the second elastic telescopic rod of the other rotating part is connected to a cutting knife seat.

[0015] Preferably, a side plate is fixedly provided on the support plate, and a rotating shaft is rotatably connected to the side plate, a driven gear and a winding reel are provided on the rotating shaft, the telescopic end of the first elastic telescopic rod is connected to a rack plate meshing with the driven gear, and tooth groups are evenly distributed on the rack plate, a pull rope is wound around the winding reel, and the end of the pull rope away from the winding reel is connected to the cutting knife seat.

[0016] Preferably, the cutting knife seat includes a movable plate fixedly connected to the second elastic telescopic rod, the movable plate is slidably connected to the support plate, a sliding groove is provided on the movable plate, a sliding seat is slidably connected in the sliding groove, a knife body connected to a pull rope is provided on the sliding seat, and an elastic element is provided between the sliding seat and the movable plate.

[0017] Preferably, the limit seat comprises a fixing plate fixed on the workbench, the fixing plate is threadedly connected with a screw, one end of the screw is connected to a limit plate slidably connected to the workbench, and the limit plate and the flexible coil are movably opposed to each other.

[0018] Preferably, the tensioning seat includes a connecting plate fixed on the frame, an elastic telescopic plate is fixed on the connecting plate, an end of the elastic telescopic plate away from the connecting plate is connected to a connecting rod, and a tensioning roller that is movably abutted against the flexible coil is sleeved on the connecting rod.

[0019] The present invention also discloses a method for using a circuit board processing production line, comprising the following steps:

[0020] S1: The rolled flexible coil is sleeved on the reel, and the staff pulls one end of the flexible coil to move it along the limit seat until one end of the flexible coil is placed on the lower side of the tensioning seat;

[0021] S2: The staff controls the two driving motors of the rotating part to operate, and the two driving motors drive the rotating rods to rotate. The two rotating rods rotate relative to each other. When the rotating rods rotate, the abutment plates are driven to rotate through the sleeve and the first elastic telescopic rod. The two abutment plates approach each other until they abut against the two sides of the flexible coil. The two abutment plates pull the flexible coil down and transport it as the rotating rods rotate. During the pulling down of the flexible coil, a force is applied to the tensioning roller, so that the flexible coil between the abutment plate in contact with the flexible coil and the tensioning seat is tensioned;

[0022] S3: As the rotating rod continues to rotate, the first elastic telescopic rod connected to the abutting plate is squeezed, and the cutter seat and the cutting seat at the end of the second elastic telescopic rod begin to contact the flexible coil. As the rotating rod rotates, the second elastic telescopic rod is compressed and applies an elastic thrust to the cutting seat and the cutter seat, and the cutter seat cooperates with the cutting seat to initially punch and cut the flexible coil.

[0023] When the first elastic telescopic rod is compressed, the rack plate connected to the telescopic end of the first elastic telescopic rod moves, and the tooth group on the rack plate intermittently meshes with the driven gear. When the rack plate meshes with the driven gear, the rotating shaft drives the winding drum to reel in the pull rope, so that the pull rope pulls the knife body, and the knife body drives the slide seat to slide in the slide groove. When the rack plate is not meshed with the driven gear, the winding drum no longer reels the pull rope, and the slide seat drives the knife body to reset under the elastic force of the elastic element, so that the knife body slides back and forth on the movable plate to achieve cutting of the flexible coiled material.

[0024] S4: There are several abutment plates arranged in a circle on the rotating rod. While one set of abutment plates on the left and right sides is pulling down and cutting the flexible coil, another set of matching abutment plates abuts, clamps and pulls down the flexible coil being pulled down, thereby realizing continuous cutting processing of the flexible coil. The cut flexible coil falls onto the material guide table and enters the next processing step.

[0025] Compared with the prior art, the present invention provides a circuit board processing production line and a method of using the same, which have the following beneficial effects:

[0026] 1. The circuit board processing production line and its use method, by setting up a conveying and cutting mechanism, can automatically tension and cut the flexible coil during conveying, and the cutting component moves synchronously with the moving flexible coil, avoiding the dangerous problems caused by manual pulling and the problem of stopping the conveying of the flexible coil during cutting, thereby ensuring the circuit board cutting processing effect and processing efficiency.

[0027] 2. The circuit board processing production line and the method of using the same, by elastically rotatably connecting the abutment plate to the end of the first elastic telescopic rod, enables the abutment plates on the left and right sides to contact the flexible coil, so that when the abutment plates on the left and right sides contact the flexible coil, one side of the abutment plate always contacts the flexible coil, thereby increasing the contact area with the flexible coil and preventing the abutment plate from contacting the flexible coil only through a part of the end line as the rotating rod rotates, thereby improving the stability of the downward pull-down conveying of the flexible coil.

[0028] 3. The circuit board processing production line and the use method thereof are as follows: when the first elastic telescopic rod is compressed, the rack plate connected to the telescopic end of the first elastic telescopic rod moves, and the tooth group on the rack plate intermittently meshes with the driven gear. When the rack plate meshes with the driven gear, the rotating shaft drives the winding drum to reel in the draw rope, so that the draw rope pulls the cutter body, and the cutter body drives the slide seat to slide in the slide groove. When the rack plate is not meshed with the driven gear, the winding drum no longer reels in the draw rope, and the slide seat drives the cutter body to reset under the push of the elastic force of the elastic element, so that the cutter body slides back and forth on the movable plate, thereby realizing the cutting of the flexible coil, and solving the problem that the existing shear blade is easily damaged due to excessive collision when punching the flexible coil by downward pressure punching.

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] Example 1: Reference Figure 1 , Figure 3 and Figure 5 A circuit board processing production line includes a frame 1, a workbench 2 and a material guide table 101 for guiding materials are fixedly arranged on the frame 1, and further includes:

[0044] A reel 3, which is arranged on the workbench 2 through a bracket, and a flexible coil 4 for producing circuit boards is sleeved on the reel 3;

[0045] Limiting seats 5, which are arranged on both sides of the workbench 2 and are used to limit the range of movement of the flexible coil 4; and

[0046] The conveying and cutting mechanism comprises a rotating conveying assembly for conveying the flexible coil 4 and a cutting assembly for cutting the flexible coil 4, wherein the cutting assembly is arranged on the rotating conveying assembly;

[0047] The frame 1 is also provided with a tensioning seat 6 for tensioning the flexible coil 4, and the tensioning seat 6 is placed on the upper side of the conveying and cutting mechanism.

[0048] Specifically, the rolled flexible coil 4 is sleeved on the reel 3, and the staff pulls one end of the flexible coil 4 to make it move along the limit seat 5 until one end of the flexible coil 4 is placed on the lower side of the tensioning seat 6, and controls the conveying and cutting mechanism to work, and automatically tensions and cuts the flexible coil 4 during transportation, and the cutting component moves synchronously with the moving flexible coil 4, avoiding dangerous problems caused by manual pulling and the need to stop conveying the flexible coil 4 during cutting, thereby ensuring the circuit board cutting processing effect and processing efficiency.

[0049] Example 2: Reference Figure 1-6 , a circuit board processing production line, based on Example 1, further, the rotating conveying assembly includes two rotating parts that rotate relatively, the rotating part includes a rotating rod 7 rotatably connected to the frame 1, and a plurality of sleeves 701 are circumferentially connected to the rotating rod 7, and a first elastic telescopic rod 702 is arranged on the sleeve 701, and an abutment plate 703 that movably abuts against the flexible coil 4 is arranged at one end of the first elastic telescopic rod 702 away from the sleeve 701, and a driving motor 704 for driving the rotating rod 7 to rotate is fixedly provided on the frame 1.

[0050] Furthermore, the tensioning seat 6 includes a connecting plate 601 fixed on the frame 1, on which an elastic telescopic plate 602 is fixed, and one end of the elastic telescopic plate 602 away from the connecting plate 601 is connected to a connecting rod 603, on which a tensioning roller 604 is sleeved and movably abuts against the flexible coil 4.

[0051] Specifically, the staff controls the two driving motors 704 of the rotating part to operate, and the two driving motors 704 drive the rotating rod 7 to rotate, and the two rotating rods 7 rotate relative to each other. When the rotating rod 7 rotates, the abutment plate 703 is driven to rotate through the sleeve 701 and the first elastic telescopic rod 702, and the two abutment plates 703 approach each other until they abut against the two sides of the flexible coil 4. The two abutment plates 703 pull the flexible coil 4 down and transport it as the rotating rod 7 rotates. During the period when the flexible coil 4 is pulled down, a force is applied to the tensioning roller 604, so that the abutment plates 703 in contact with the flexible coil 4 are pulled to the tensioning roller 604. The flexible coil 4 between the tight seats 6 is tensioned to avoid uneven cutting due to the relaxation of the flexible coil 4, thereby ensuring the cutting quality of the flexible coil 4; a plurality of abutment plates 703 are arranged in a circle on the rotating rod 7. While one group of abutment plates 703 on the left and right sides are pulling down the flexible coil 4 for cutting, another group of matching abutment plates 703 abuts, clamps and pulls down the flexible coil 4 being pulled down, thereby realizing continuous cutting processing of the flexible coil 4. The cut flexible coil 4 falls onto the material guide table 101 and enters the next processing step, thereby improving the production and processing efficiency of the circuit board.

[0052] Example 3: Reference Figure 6 , Figure 8 and Fig.10 A circuit board processing production line, based on Example 2, further, a second screw hole 7021 is opened on the first elastic telescopic rod 702, and a plurality of first screw holes 7011 matching with the second screw holes 7021 are opened along the axial direction of the sleeve 701, and the first screw hole 7011 and the second screw hole 7021 are threadedly connected with bolts 11.

[0053] Specifically, the bolt 11 is used to insert and lock the second screw hole 7021 with the first screw hole 7011 at different positions in the sleeve 701, thereby adjusting the overall distance between the first elastic telescopic rod 702 and the sleeve 701, thereby adjusting the clamping distance of the flexible coil 4 by the abutment plate 703 when the first elastic telescopic rod 702 rotates with the rotating rod 7, thereby adjusting the cutting size of the flexible coil 4.

[0054] Example 4: Reference Figure 6 , Figure 7 and Figure 8 , a circuit board processing production line, based on Example 3, further, the abutment plate 703 is rotatably connected to the end of the first elastic telescopic rod 702 through a pin shaft, and a torsion spring for driving the abutment plate 703 to reset and rotate is sleeved on the pin shaft.

[0055] Specifically, the abutment plate 703 is elastically rotatably connected to the end of the first elastic telescopic rod 702, so that when the abutment plates 703 on the left and right sides contact the flexible coil 4, one side of the abutment plate 703 is always in contact with the flexible coil 4, thereby increasing the contact area and friction with the flexible coil 4, and avoiding the abutment plate 703 contacting the flexible coil 4 only through a partial end line as the rotating rod 7 rotates, thereby improving the stability of the downward pull-down conveying of the flexible coil 4.

[0056] Example 5: Reference Figure 1-9 , a circuit board processing production line, based on Example 4, further, the cutting component includes a support plate 8 fixedly mounted on the first elastic telescopic rod 702, and a second elastic telescopic rod 801 is fixedly mounted on the support plate 8, wherein the telescopic end of the second elastic telescopic rod 801 of one rotating part is connected to a cutting seat 802, and the telescopic end of the second elastic telescopic rod 801 of the other rotating part is connected to a cutting seat 803.

[0057] Specifically, as the rotating rod 7 continues to rotate, the first elastic telescopic rod 702 connected to the abutment plate 703 is squeezed, and the cutter seat 803 and the cutting seat 802 at the end of the second elastic telescopic rod 801 begin to contact the flexible coil 4. As the rotating rod 7 rotates, the second elastic telescopic rod 801 is compressed and applies an elastic thrust to the cutting seat 802 and the cutter seat 803. The cutter seat 803 cooperates with the cutting seat 802 to punch the flexible coil 4, which solves the problem that the existing shear blade is easily damaged due to excessive collision when punching the flexible coil 4 through the rigid punching method of pressing down.

[0058] Example 6: Reference Figure 1-9 , a circuit board processing production line, based on Example 5, further, a side plate 9 is fixedly provided on the support plate 8, and a rotating shaft 901 is rotatably connected to the side plate 9, and a driven gear 902 and a winding drum 903 are provided on the rotating shaft 901, and the telescopic end of the first elastic telescopic rod 702 is connected to a rack plate 10 meshing with the driven gear 902, and tooth groups 1001 are equidistantly distributed on the rack plate 10, and a pull rope 9031 is wound around the winding drum 903, and the end of the pull rope 9031 away from the winding drum 903 is connected to the cutter seat 803.

[0059] Furthermore, the cutting seat 803 includes a movable plate 8031 ​​fixedly connected to the second elastic telescopic rod 801, the movable plate 8031 ​​is slidably connected to the support plate 8, a sliding groove 8032 is provided on the movable plate 8031, a sliding seat 8033 is slidably connected in the sliding groove 8032, a knife body 8034 connected to the pull rope 9031 is provided on the sliding seat 8033, and an elastic element 8035 is provided between the sliding seat 8033 and the movable plate 8031.

[0060] Specifically, as the rotating rod 7 continues to rotate, the first elastic telescopic rod 702 connected to the abutment plate 703 is squeezed, and the cutter seat 803 and the cutting seat 802 at the end of the second elastic telescopic rod 801 begin to contact the flexible coil 4. As the rotating rod 7 rotates, the second elastic telescopic rod 801 is compressed and applies an elastic thrust to the cutting seat 802 and the cutter seat 803. The cutter seat 803 cooperates with the cutting seat 802 to perform a preliminary punching of the flexible coil 4. When the first elastic telescopic rod 702 is compressed, the rack plate 10 connected to the telescopic end of the first elastic telescopic rod 702 moves, and the tooth group 1001 on the rack plate 10 is intermittently meshed with the driven gear 902. When the wheel 902 is engaged, the rotating shaft 901 drives the winding drum 903 to reel in the pull rope 9031, so that the pull rope 9031 pulls the knife body 8034, and the knife body 8034 drives the slide 8033 to slide in the slide groove 8032. When the rack plate 10 is not engaged with the driven gear 902, the winding drum 903 no longer reels the pull rope 9031, and the slide 8033 drives the knife body 8034 to reset under the elastic force of the elastic element 8035. The elastic element 8035 is set as a spring, so that the knife body 8034 slides back and forth on the movable plate 8031, thereby realizing the cutting of the flexible coil 4, ensuring the cutting quality of the flexible coil 4, and then ensuring the production and processing quality of the circuit board.

[0061] Example 7: Reference Figure 1 , Figure 3 and Fig.11 , a circuit board processing production line, based on Example 6, further, the limit seat 5 includes a fixed plate 501 fixed on the workbench 2, the fixed plate 501 is threadedly connected with a screw 502, one end of the screw 502 is connected to a limit plate 503 slidably connected to the workbench 2, and the limit plate 503 is movably opposed to the flexible coil 4.

[0062] Specifically, the staff rotates the screw 502 according to the size of the flexible coil 4, so that the screw 502 drives the limit plate 503 to move relative to the fixed plate 501, adjusts the distance between the limit plates 503 on both sides of the workbench 2, and limits the two sides of the flexible coil 4 to prevent the flexible coil 4 from shifting during the downward conveying and cutting process, thereby ensuring the cutting effect of the flexible coil 4 and improving the processing quality of the circuit board.

[0063] The present invention also discloses a method for using a circuit board processing production line, comprising the following steps:

[0064] S1: The rolled flexible coil 4 is sleeved on the reel 3, and the staff pulls one end of the flexible coil 4 to move it along the limit seat 5 until one end of the flexible coil 4 is placed on the lower side of the tensioning seat 6;

[0065] S2: The staff controls the two driving motors 704 of the rotating part to operate, and the two driving motors 704 drive the rotating rod 7 to rotate. The two rotating rods 7 rotate relatively. When the rotating rod 7 rotates, the abutment plate 703 is driven to rotate through the sleeve 701 and the first elastic telescopic rod 702. The two abutment plates 703 approach each other until they abut against the two sides of the flexible coil 4. The two abutment plates 703 pull the flexible coil 4 down and transport it as the rotating rod 7 rotates. During the period when the flexible coil 4 is pulled down, a force is applied to the tensioning roller 604, so that the flexible coil 4 between the abutment plate 703 in contact with the flexible coil 4 and the tensioning seat 6 is tensioned;

[0066] S3: As the rotating rod 7 continues to rotate, the first elastic telescopic rod 702 connected to the abutting plate 703 is squeezed, and the cutter seat 803 and the cutting seat 802 at the end of the second elastic telescopic rod 801 begin to contact the flexible coil 4. As the rotating rod 7 rotates, the second elastic telescopic rod 801 is compressed and applies an elastic thrust to the cutting seat 802 and the cutter seat 803, and the cutter seat 803 cooperates with the cutting seat 802 to initially punch the flexible coil 4.

[0067] When the first elastic telescopic rod 702 is compressed, the rack plate 10 connected to the telescopic end of the first elastic telescopic rod 702 moves, and the tooth group 1001 on the rack plate 10 is intermittently meshed with the driven gear 902. When the rack plate 10 is meshed with the driven gear 902, the rotating shaft 901 drives the winding drum 903 to reel in the drawstring 9031, so that the drawstring 9031 pulls the knife body 8034, and the knife body 8034 drives the slide seat 8033 to slide in the slide groove 8032. When the rack plate 10 is not meshed with the driven gear 902, the winding drum 903 no longer reels the drawstring 9031, and the slide seat 8033 drives the knife body 8034 to reset under the elastic force of the elastic element 8035, so that the knife body 8034 slides back and forth on the movable plate 8031, thereby realizing the cutting of the flexible coil 4.

[0068] S4: There are a plurality of abutment plates 703 arranged in a circle on the rotating rod 7. While one group of abutment plates 703 on the left and right sides is pulling down and cutting the flexible coil 4, another group of matching abutment plates 703 abuts, clamps and pulls down the flexible coil 4 being pulled down, thereby realizing continuous cutting processing of the flexible coil 4. The cut flexible coil 4 falls onto the material guide table 101 and enters the next processing step.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

8. A circuit board processing production line according to claim 7, characterized in that: The tensioning seat (6) comprises a connecting plate (601) fixedly mounted on the frame (1), an elastic telescopic plate (602) being fixedly mounted on the connecting plate (601), an end of the elastic telescopic plate (602) away from the connecting plate (601) being connected to a connecting rod (603), and a tensioning roller (604) being sleeved on the connecting rod (603) and movably abutting against the flexible coil (4).

9. A method for using the circuit board processing production line according to claim 8, characterized in that: The following steps are involved: S1: The rolled flexible coil (4) is sleeved on the reel (3), and a worker pulls one end of the flexible coil (4) to move it along the limit seat (5) until one end of the flexible coil (4) is placed on the lower side of the tensioning seat (6); S2: The staff controls the two driving motors (704) of the rotating part to operate, and the two driving motors (704) drive the rotating rod (7) to rotate. The two rotating rods (7) rotate relative to each other. When the rotating rod (7) rotates, the abutment plate (703) is driven to rotate through the sleeve (701) and the first elastic telescopic rod (702). The two abutment plates (703) approach each other until they abut against two sides of the flexible coil (4). The two abutment plates (703) pull the flexible coil (4) downward for transportation as the rotating rod (7) rotates. During the period when the flexible coil (4) is pulled downward, a force is applied to the tensioning roller (604), so that the flexible coil (4) between the abutment plate (703) in contact with the flexible coil (4) and the tensioning seat (6) is tensioned. S3: As the rotating rod (7) continues to rotate, the first elastic telescopic rod (702) connected to the abutment plate (703) is squeezed, and the cutter seat (803) and the cutting seat (802) at the end of the second elastic telescopic rod (801) begin to contact the flexible coiled material (4). As the rotating rod (7) rotates, the second elastic telescopic rod (801) is compressed and applies an elastic thrust to the cutting seat (802) and the cutter seat (803), and the cutter seat (803) cooperates with the cutting seat (802) to perform preliminary punching of the flexible coiled material (4); When the first elastic telescopic rod (702) is compressed, the rack plate (10) connected to the telescopic end of the first elastic telescopic rod (702) moves, and the tooth set (1001) on the rack plate (10) intermittently meshes with the driven gear (902). When the rack plate (10) and the driven gear (902) are meshed, the rotating shaft (901) drives the winding drum (903) to reel in the pull rope (9031), so that the pull rope (9031) pulls the knife body (8034), and the knife body (8034) drives the slide seat (8033) to slide in the slide groove (8032). When the rack plate (10) is not meshed with the driven gear (902), the winding drum (903) no longer reels the pull rope (9031). The slide seat (8033) drives the knife body (8034) to reset under the elastic force of the elastic element (8035), so that the knife body (8034) slides back and forth on the movable plate (8031), thereby realizing the cutting of the flexible coil (4). S4: A plurality of abutment plates (703) are arranged in a circle on the rotating rod (7). While one group of abutment plates (703) on the left and right sides is pulling down and cutting the flexible coil (4), another group of matching abutment plates (703) abuts, clamps and pulls down the flexible coil (4) being pulled down, thereby realizing continuous cutting processing of the flexible coil (4). After cutting, the flexible coil (4) falls onto the material guide table (101) and enters the next processing step.
