[0002] Chinese patent application number CN209699273U discloses a fully automatic stamping and taping machine. By innovatively integrating a feeding mechanism, a punching and shaping mechanism, a cutting mechanism, and a waste material cutting mechanism into the stamping die, and providing a carrier tape slot for conveying the carrier tape, the machine achieves the goal of organically combining the stamping and forming of SMD components with the tape taping process. This allows SMD components to be automatically loaded as raw materials for automatic stamping, forming, cutting, and packaging. This also allows for the cutting and unloading of waste materials, significantly improving the efficiency of SMD component production and packaging, meeting the needs of high-speed automated production on SMT production lines. Compared to systems where SMD components are first stamped into tape, production efficiency is further improved.

[0003] In the braiding machine disclosed in the above-mentioned document, the raw material strip after punching out the shape is bent at a set angle by a bending lower die block and a bending upper die block at a bending mechanism, and the bent raw material strip is cut by a cutting blade and a cutting punch at a cutting mechanism.

[0004] However, in the above-mentioned bending method using the lower and upper die inserts, if the set angle needs to be changed during bending, the corresponding lower and upper die inserts need to be replaced. Therefore, it is necessary to produce multiple sets of lower and upper die inserts with different bending angles to meet the needs of bending the raw material strip at different angles. However, the production cost of the template is relatively high, and the production cost of producing multiple sets of lower and upper die inserts with different bending angles is relatively high. Therefore, how to bend the raw material strip at different angles without replacing the bending template is a technical problem that needs to be solved. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1, a double-track braiding machine for cutting and folding materials, such as Figure 1 As shown, it includes a frame, on which are provided two sets of position-adjustable storage carriers 1, and below which are provided a bending mechanism and a cutting mechanism, and the bending angle of the bending mechanism is adjustable; the bending mechanism includes a circumferential rotating unit, and the circumferential rotating unit is connected to a clamping unit, and when the clamping unit clamps the bending part of the component, the circumferential rotating unit drives the clamping unit to rotate to achieve bending of the component, and the rotation angle of the circumferential rotating unit is adjustable. After the clamping unit clamps the bending part of the component, the circumferential rotation unit drives the clamping unit to rotate to achieve the bending of the component. When the bending angle needs to be adjusted, the rotation angle of the circumferential rotation unit on the bending mechanism is adjusted, and the rotation angle of the circumferential rotation unit is controlled to achieve the adjustment of the bending angle, thereby achieving the unreplaceable bending lower die block and bending upper die block, and the raw material strip can be bent at different angles without the need to replace the bending template. The production cost is effectively reduced, and the technical problem of high production cost caused by the need to replace the bending lower die block and bending upper die block corresponding to the bending angle when the raw material strip is bent at different angles of the existing bending mechanism is solved.

[0024] The frame is also provided with a winding mechanism for the storage carrier tape 1 and a forming mechanism for forming the raw materials into components. The winding mechanism reels and conveys the storage carrier tape 1. The winding mechanism is, for example, a carrier tape reel assembly. The winding mechanism can also utilize the winding device disclosed in the public document in the background technology of this application specification. The winding device is a common existing structure that can realize the winding and conveying functions. The forming mechanism used in the preparation of this application is a purchased existing mechanism. This application does not limit the structure of the forming mechanism. Common existing forming mechanisms that can form corresponding components are all within the scope of consideration of this application.

[0025] Example 2, based on Example 1, a double-track braiding machine that is convenient for cutting and folding materials, such as Figure 1 As shown, the bending mechanism includes two sets of circumferential rotation units, each connected to the two ends of the clamping unit. The two sets of circumferential rotation units simultaneously and in the same direction drive the clamping unit to bend the component. The presence of two sets of circumferential rotation units helps ensure structural stability.

[0026] Example 3, based on Example 2, a double-track braiding machine that is convenient for cutting and folding materials, such as Figure 1 and Figure 2 As shown, the circumferential rotation unit includes a support frame 2, on which a connecting shaft 3 is rotatably mounted. A gear 4 is connected to one end of the connecting shaft 3. A support plate 5 is connected to the support frame 2, and a rack 6 is slidably mounted on the support plate 5. The rack 6 meshes with the gear 4. A bending cylinder 7 is mounted on the frame, and its piston is connected to the rack 6. The piston's extension and retraction direction is parallel to the direction of movement of the rack 6 on the support plate 5. The clamping unit is mounted on the connecting shaft 3. When the bending cylinder 7 extends, it moves the rack 6, which in turn rotates the gear 4 clockwise, which in turn rotates the connecting shaft 3 clockwise, causing the clamping unit to rotate clockwise along with the connecting shaft 3. The meshing of the rack 6 and the gear 4 converts the linear motion of the bending cylinder 7 into circumferential rotation of the connecting shaft 3. The linear movement of the bending cylinder 7 determines the angle of circumferential rotation of the connecting shaft 3, which in turn determines the bending angle of the component, thereby enabling controllable adjustment of the component bending angle. The support frame 2 and the connecting shaft 3 are rotatably connected via bearings, and the connecting shaft 3 and the gear 4 are fixedly connected via screws.

[0027] Example 4, based on Example 3, a double-track braiding machine that is convenient for cutting and folding materials, such as Figure 1 、 Figure 2 and Figure 3 As shown, the clamping unit includes a groove 8 provided on the connecting shaft 3. A scissor-type structure is provided within the groove 8. Two clamping blocks 9 are located on top of the scissor-type structure. The scissor-type structure allows for adjustable spacing between the two clamping blocks 9. The scissor-type structure allows for adjustable spacing between the two clamping blocks 9. When the clamping unit is required to clamp a component, the spacing between the two clamping blocks 9 is controlled to decrease, thereby clamping the component. This facilitates bending the component as the clamping unit rotates clockwise with the connecting shaft 3. Once the component is bent, the spacing between the two clamping blocks 9 is controlled to increase, allowing the clamping unit to release the component.

[0028] Example 5, based on Example 4, a double-track braiding machine that is convenient for cutting and folding materials, such as Figure 1 、 Figure 2 and Figure 3As shown, the scissor-type structure includes a first connecting rod 10 and a second connecting rod 11. The middle parts of the first connecting rod 10 and the second connecting rod 11 are hinged. Two clamping blocks 9 are respectively arranged at the top of the first connecting rod 10 and the top of the second connecting rod 11. The bottom of the first connecting rod 10 is hinged to the connecting shaft 3. A movable seat 12 is slidingly provided in the groove 8. The bottom of the second connecting rod 11 is hinged to the movable seat 12. By lateral movement of the movable seat 12, the bottoms of the first connecting rod 10 and the second connecting rod 11 are brought closer or farther away, so that the tops of the first connecting rod 10 and the second connecting rod 11 are brought closer or farther away, and the two clamping blocks 9 at the tops of the first connecting rod 10 and the second connecting rod 11 are brought closer or farther away, thereby achieving adjustable control of the spacing between the two clamping blocks 9. The lateral movement of the movable seat 12 is converted into adjustment of the lateral spacing between the two clamping blocks 9 and adjustment of the longitudinal height. That is, when the movable seat 12 moves lateraly to bring the bottoms of the first connecting rod 10 and the second connecting rod 11 closer together, the first connecting rod 10 and the second connecting rod 11 are brought closer or farther away. 10 and the top of the second connecting rod 11 are brought closer, and at the same time, the height of the top of the first connecting rod 10 and the second connecting rod 11 is increased, so that the two clamping blocks 9 are raised to the position corresponding to the clamping components, and the distance between the two clamping blocks 9 is reduced to clamp the components; when the movable seat 12 moves laterally, the bottom of the first connecting rod 10 and the second connecting rod 11 are moved away, so that the top of the first connecting rod 10 and the second connecting rod 11 are moved away, and at the same time, the height of the top of the first connecting rod 10 and the second connecting rod 11 is reduced, so that the distance between the two clamping blocks 9 is increased to release the components and the height of the two clamping blocks 9 is reduced, away from the components.

[0029] Example 6, based on Example 5, a double-track braiding machine that is convenient for cutting and folding materials, such as Figure 1 、 Figure 2 and Figure 3 As shown, a clamping cylinder 13 is provided in the groove 8, and the piston of the clamping cylinder 13 is connected to the movable seat 12. The clamping cylinder 13 is provided to control the position of the movable seat 12. The position of the movable seat 12 is controlled by extending or retracting the clamping cylinder 13, thereby achieving the purpose of raising the two clamping blocks 9 and clamping the components through the lateral movement of the clamping cylinder 13.

[0030] Example 7, based on Example 6, a double-track braiding machine that is convenient for cutting and folding materials, such as Figure 1As shown, the cutting mechanism includes a cutting cylinder 14 and a supporting cylinder 15, which are arranged on opposite sides of the storage carrier 1. The cutting cylinder 14 is provided with a cutter 16 at one end near the storage carrier 1, and the supporting cylinder 15 is provided with a cutting pad 17 at the other end near the storage carrier 1. The cutting cylinder 14 drives the cutter 16 to extend to cut the components, and the supporting cylinder 15 can drive the cutting pad 17 to extend to support the components. The provision of the cutting pad 17 facilitates the cutting of the components by the cutter 16, which is conducive to achieving smooth cutting of the components.

[0031] Example 8, based on Example 7, a double-track braiding machine that is convenient for cutting and folding materials, such as Figure 1 As shown, the cutting cylinder 14 is located between the two groups of the storage carrier tapes 1. Pistons are provided at opposite ends of the cutting cylinder 14, and the two pistons are respectively connected to the cutters 16. That is, the cutting cylinder 14 is located between the two groups of the storage carrier tapes 1. When the cutting cylinder 14 is in operation, the two pistons are simultaneously extended, and the two pistons respectively extend the cutters 16. The two cutters 16 synchronously cut the components on the two storage carrier tapes 1, greatly improving the efficiency of the cutting work.

[0032] Example 9, based on any one of Examples 1 to 8, a double-track braiding machine that is convenient for cutting and folding materials, such as Figure 1 、 Figure 2 and Figure 3 As shown, the frame is provided with a moving motor 18, the output end of which is connected to a moving gear 19. The storage carrier 1 includes a body 20, which is provided with a cavity 21 for placing components. A moving rack 22 is connected to the side of the body 20, and the moving gear 19 meshes with the moving rack 22. The moving motor 18 drives the moving gear 19 to rotate, and when the moving gear 19 meshes with the moving rack 22, the storage carrier 1 is ultimately driven to move.

[0033] When the embodiment 9 is implemented, first, after the components are formed by the forming mechanism, they are placed in the cavity hole 21 of the storage carrier 1, and the moving motor 18 is started. The moving motor 18 drives the moving gear 19 to rotate. When the moving gear 19 is engaged with the moving rack 22, the storage carrier 1 is finally driven to move. When the components in the cavity hole 21 pass through the bending mechanism and the cutting mechanism in sequence, when the components reach the bending mechanism, the moving motor 18 is turned off, and the clamping cylinder 13 is started. The clamping cylinder 13 extends and drives the moving seat 12 to move horizontally, so that the first connecting rod 10 and the second The bottom of the connecting rod 11 approaches, so that the top of the first connecting rod 10 and the second connecting rod 11 approaches, and at the same time, the top height of the first connecting rod 10 and the second connecting rod 11 rises, so that the two clamping blocks 9 rise to the position corresponding to the clamping components, and the distance between the two clamping blocks 9 is reduced to clamp the components, and then the bending cylinder 7 is started, and the bending cylinder 7 extends to drive the rack 6 to move, and then drives the gear 4 to rotate clockwise, and then drives the connecting shaft 3 to rotate clockwise. The clamping unit rotates clockwise with the connecting shaft 3 to achieve the bending of the components, and then the clamping cylinder 13 is closed, and the clamping The tightening cylinder 13 drives the movable seat 12 to move laterally, so that the bottom of the first connecting rod 10 and the second connecting rod 11 are separated, and the top of the first connecting rod 10 and the second connecting rod 11 are separated. At the same time, the height of the top of the first connecting rod 10 and the second connecting rod 11 is reduced, so that the distance between the two clamping blocks 9 is increased, the components are released, and the height of the two clamping blocks 9 is reduced, away from the components, and then the bending cylinder 7 is closed. When the bending cylinder 7 retracts, it drives the rack 6 to move, and then drives the gear 4 to rotate counterclockwise, and then drives the connecting shaft 3 to rotate counterclockwise, and the clamping unit rotates along with the connecting shaft 3. Rotate counterclockwise to the initial position, then start the moving motor 18 to continue to drive the roll carrier 1 to move. When the bent component moves to the cutting mechanism, start the support cylinder 15 and the cutting cylinder 14 in sequence. After the cutting pad 17 extends and supports the component, the cutter 16 extends to cut the bent component. After cutting is completed, turn off the support cylinder 15 and the cutting cylinder 14. The cutting pad 17 and the cutter 16 retract to the initial position, and then continue to start the moving motor 18 to continue to drive the roll carrier 1 to move, and control the cut components to the next step. When the bending angle needs to be changed, the corresponding bending angle can be obtained based on the calculated length of the bending cylinder 7. Then, the corresponding bending angle can be achieved by adjusting the length of the bending cylinder 7.

[0034] Example 10, based on Example 9, a double-track braiding machine that is convenient for cutting and folding materials, such as Figure 1As shown, the frame is equipped with a PLC control system, and the bending cylinder 7, clamping cylinder 13, cutting cylinder 14, supporting cylinder 15, and mobile motor 18 are all connected to the PLC control system. The PLC control system is set up to control the automated operation of the entire braiding machine. When the bending cylinder 7, clamping cylinder 13, cutting cylinder 14, supporting cylinder 15, and mobile motor 18 are all connected to the PLC control system, the startup and shutdown of the bending cylinder 7, clamping cylinder 13, cutting cylinder 14, supporting cylinder 15, and mobile motor 18, as well as the timing of startup, are effectively controlled, ensuring the orderly automated operation of the entire braiding machine. When the bending angle needs to be changed, the corresponding bending angle can be obtained based on the calculated length of the bending cylinder 7 extension. The specific value of the bending cylinder 7 extension length is then changed in the PLC control system.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
