[0001] This invention belongs to the technical field of linear processing parts production equipment, specifically relating to a flipping and conveying device and production line for linear processing parts. Background Technology

[0002] Currently, some linear processed parts require consistent orientation due to their structural processing requirements, such as unidirectional barbed sutures used in the medical field. Unidirectional barbed sutures have pairs of blunt-edged fishbone-like protrusions on both sides. Therefore, in the production of unidirectional barbed sutures, the suture needs to be crimped with a suture needle at one end and the tail welded at the other end, and the directions cannot be reversed.

[0003] In the existing processing technology for unidirectional barbed sutures, the sutures need to be crimped and welded after the barbs are cut. However, after the barbs are cut, the sutures often fall into the storage box in a messy manner. The current method of sorting the direction of the sutures is done manually, which greatly reduces the speed of crimping and welding. Summary of the Invention

Detailed Implementation

[0021] The invention will now be described in further detail with reference to the accompanying drawings.

[0022] It should be noted that the terms such as "upper", "lower", "left", "right", "front", and "back" used in the invention are only for clarity of description and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0023] Example 1 like Figure 1 As shown, a flipping and transporting device for linear processed parts includes a linear module 1, an angle guide sleeve 2, and a gripper mechanism 3; the angle guide sleeve 2 is detachably sleeved on the outside of the moving track of the linear module 1; the linear module 1 can be a common linear slide or a ball screw.

[0024] like Figure 1 and 2 As shown, the gripper mechanism 3 is connected to the moving part of the linear module 1. When the linear module 1 is a ball screw, the nut of the ball screw can rotate around the ball screw axis and translate axially when the ball screw rotates. The gripper mechanism 3 is mounted on the nut. Of course, in some other embodiments, if the nut of the ball screw can only move axially, the gripper mechanism 3 can also be rotatably connected to the nut. In some other embodiments, the linear module 1 is a linear slide, and the gripper mechanism 3 is rotatably connected to the moving part of the linear module 1, that is, the gripper mechanism 3 can translate and rotate along the linear module 1.

[0025] The circumferential surface of the angle guide sleeve 2 is provided with a threaded angle guide groove 21, or an angle guide groove 21 that combines threaded and straight shapes. When the angle guide groove 21 is projected onto the end face of the angle guide sleeve 2, the included angle between the two ends of the angle guide groove 21 is the set flip angle of the linear workpiece. The included angle between the two ends of the angle guide groove 21 can usually be set to 30°, 60°, 90°, 180° or 270°, etc. The number of thread turns at the two ends of the angle guide groove 21 can be set as needed. When the shape of the angle guide groove 21 is a combination of threaded and straight shapes, the order of the threaded and straight shapes and the number of them can be set according to production experience. That is, the path of the angle guide groove 21 is the movement path of the linear workpiece, and the shape of the angle guide groove 21 can be adjusted according to the needs of flipping and handling.

[0026] like Figure 3 As shown, the gripper mechanism 3 is connected to the moving part of the linear module 1 and can slide continuously or intermittently along the angle guide groove 21 to make the linear workpiece flip and move along the angle guide groove 21. By controlling the starting frequency of the linear module 1, the continuous or intermittent sliding of the gripper mechanism 3 is controlled, that is, the traveling speed of the linear module 1 is the same as the traveling speed of its adapted preceding processing step. That is, if the preceding processing step needs to move intermittently, the linear module 1 receives a pulse signal of a fixed number of steps. The present invention has a simple overall structure, high flipping and handling efficiency, and is suitable for the handling and flipping of large batches of products. The setting of the angle guide groove 21 can ensure that the linear workpiece flips during the movement. The angle guide groove 21 and the linear module 1 work together to ensure the moving and flipping speed and flipping path of the linear workpiece, thereby improving the adaptability with other devices in the production line and avoiding the breakage of the linear workpiece due to the mismatch between the flipping and moving speeds.

[0027] In some other embodiments, such as Figure 4As shown, there are multiple angle guide sleeves 2; when the angle guide groove 21 is projected onto the end face of the angle guide sleeve 2, the included angles at both ends of the angle guide groove 21 of each angle guide sleeve 2 are different; in the axial direction of the angle guide sleeve 2, the distances between the beginning and end ends of the angle guide groove 21 on multiple angle guide sleeves 2 of different specifications are the same; in use, one of the angle guide sleeves 2 is selected and installed outside the linear module 1, that is, the angle guide grooves 21 of multiple angle guide sleeves 2 are different, and the difference in the angle guide grooves 21 is to allow for selection according to different flipping requirements in actual use; in the axial distance of the angle guide sleeves 2, the angle guide grooves of different angle guide sleeves 2 are different. The distance between the two ends of the groove 21 is the same, thus adapting to different lengths of linear workpieces. When the linear workpiece moves to the tail of the angle guide sleeve 2, the linear module 1 stops operating. Specifically, a proximity switch can be set on the angle guide groove 21. When the linear workpiece reaches the tail of the angle guide groove 21, the power drive of the linear module 1 stops working. Of course, the action time of the linear module 1 can also be directly controlled, or a linear module 1 with a different shaft length can be replaced. The two ends of the angle guide groove 21 extend to or are close to the two ends of the angle guide sleeve 2. Multiple angle guide sleeves 2 with different travel paths can be set to meet the needs of multi-angle flipping and multi-distance handling of linear workpieces.

[0028] like Figure 5 and 6 As shown, the gripper mechanism 3 includes a gripper fixing member 31, a clamping plate 32, and a driving mechanism 33; the gripper fixing member 31 is provided with at least two straight sliding grooves 4; the heads of all sliding grooves 4 gradually approach each other, that is, all sliding grooves 4 form a tapered structure; there are also at least two clamping plates 32, which are correspondingly slidably connected in the sliding grooves 4 to clamp and release the linear workpiece; when there are two clamping plates 32, the two clamping plates 32 are arranged opposite each other. Of course, one clamping plate 32 can also be installed in multiple sliding grooves 4.

[0029] The drive mechanism 33 can simultaneously drive all clamping plates 32 to slide along the sliding groove 4; when the clamping plates 32 move to the first position of the sliding groove 4, all clamping plates 32 move closer to each other to clamp the linear workpiece; when the clamping plates 32 move in the opposite direction to the second position of the sliding groove 4, all clamping plates 32 move further away from each other to release the linear workpiece, that is, the first position of the sliding groove 4 is close to the head of the sliding groove 4.

[0030] like Figure 6As shown, the drive mechanism 33 includes a tapered threaded shaft 331 and a gripper drive motor 332. The large-diameter end of the tapered threaded shaft 331 is connected to the output shaft of the gripper drive motor 332 through a gripper motor coupling. A gripper motor fixing plate 333 is provided on the gripper fixing member 31, thereby connecting the gripper drive motor 332 to the gripper fixing member 31. The gripper fixing member 31 has a hollow structure, and the sliding groove 4 is provided on the inner wall of the gripper fixing member 31. The clamping plate 32 has a thread on the side opposite to the sliding groove 4, and the thread is located on the outside of the sliding groove 4. The tapered threaded shaft 331 meshes with the thread of the clamping plate 32. When the tapered threaded shaft 331 rotates about its own axis, it drives the clamping plate 32 to move along the sliding groove 4. That is, the area of ​​the front section of the tapered threaded shaft 331 that needs to be tapped is designed to have the same inclination as the sliding groove 4 to ensure normal thread engagement.

[0031] Alternatively, the gripper fixing member 31 is in the shape of a triangular truncated pyramid, and the clamping plates 32 are three in number and distributed one-to-one on the three sides of the gripper fixing member 31; the sliding groove 4 is parallel to the surface of the gripper fixing member 31.

[0032] Specifically, the clamping plate 32 includes a straight segment 321 and an oblique segment 322 connected end to end, and the straight segment 321 and the oblique segment 322 can be integrally formed; the oblique segment 322 is parallel to the bottom of the sliding groove 4, and the oblique segment 322 is slidably connected to the sliding groove 4 to ensure that when the clamping plate 32 grips an item, the clamping plate 32 is parallel or tangent to the contact surface and will not be inserted at an angle; the cross-section of the sliding groove 4 is T-shaped, and the cross-sectional shape of the oblique segment 322 is consistent with that of the sliding groove 4, thereby ensuring the stability of the connection between the clamping plate 32 and the sliding groove 4.

[0033] Furthermore, the gripper motor fixing plate 333 has three bosses 334 on the side facing the gripper fixing member 31. The gripper fixing member 31 is mounted on the bosses 334. The presence of the bosses 334 can extend the sliding distance of the clamping plate 32 and will not interfere with the gripper motor fixing plate 333 when the clamping plate 32 is opened. The gripper motor fixing plate 333 or the gripper fixing member 31 is mounted on the nut of the ball screw.

[0034] In some other embodiments, the gripper fixing member 31 can be a solid structure (not shown in the figure), the sliding groove 4 is located on the outside of the gripper fixing member 31, and the heads of the multiple sliding grooves 4 gradually approach each other. Correspondingly, the driving structure is a conical sleeve, and the inner wall of the conical sleeve is provided with threads. The conical sleeve engages with the threads of the clamping plate 32. When the conical sleeve rotates, it drives the clamping plate 32 to move along the sliding groove 4 located on the outside of the gripper fixing member 31.

[0035] like Figure 3As shown, further, the gripper motor fixing plate 333 or the gripper fixing component 31 is connected to the nut of the ball screw via the connecting shaft 102. That is, one end of the connecting shaft 102 is installed on the nut of the ball screw, and the other end is provided with a mounting hole. The gripper motor fixing plate 333 or the gripper fixing component 31 is installed in the mounting hole by common connecting parts such as screws or bolts. The axis of the connecting shaft 102 is perpendicular to the axis of the ball screw. The outer side of the connecting shaft 102 is coaxially sleeved with an anti-wear bearing 101. The outer ring of the anti-wear bearing 101 contacts the groove of the angle guide groove 21, thereby ensuring the smoothness of the connecting shaft 102 when sliding in the angle guide groove 21 and reducing the wear of the angle guide groove 21.

[0036] like Figure 2 and 7 As shown, specifically, the linear module 1 is mounted between the first support base 11 and the second support base 12; the first support base 11 is detachably connected to the linear module 1. Of course, the linear module 1 can also be detachably connected to both the first support base 11 and the second support base 12 to allow for the replacement of linear modules 1 with different configurations; a first connecting member 13 is provided on the opposing surfaces of the first support base 11 and the second support base 12, and a second connecting member 14 is provided on the angle guide sleeve 2 to cooperate with the first connecting member 13. The first connecting member 13 and the second connecting member 14 cooperate to achieve a detachable connection between the angle guide sleeve 2 and the first support base 11 and the second support base 12; the first connecting member 13 and the second connecting member 14 cooperate to ensure the correct flipping angle of the clamping plate 32 and prevent the angle guide sleeve 2 from rotating circumferentially.

[0037] The first connector 13 is a keyway, and the second connector 14 is a key block, or the first connector 13 is a key block and the second connector 14 is a keyway; there are multiple first connectors 13 and multiple second connectors 14; both the first support base 11 and the second support base 12 are provided with positioning rings 15 that protrude outward from their surfaces; the positioning rings 15 are located on the opposing surfaces of the first support base 11 and the second support base 12; the positioning rings 15 are adapted to the angle guide sleeve 2; when the angle guide sleeve 2 is installed, the inner ring of the angle guide sleeve 2 cooperates with the positioning rings 15 to prevent the angle guide sleeve 2 from collapsing inward during installation due to the slotting.

[0038] Working process: Based on the required flipping angle and length of the linear workpiece, select a suitable angle guide sleeve 2 and install it between the first support 11 and the second support 12; start the power of the tapered threaded shaft 331 to make it rotate forward. During the forward rotation, all clamping plates 32 move towards the small end of the gripper fixing member 31. When the clamping plates 32 move to the first position of the sliding groove 4, the straight sections 321 of all clamping plates 32 come together to clamp the linear workpiece; after clamping is completed, the tapered threaded shaft 331 stops rotating. The power motor of the linear module 1 drives the gripper mechanism 3 to move forward along the angle guide groove 21. When it moves to the tail of the angle guide groove 21, the power of the tapered thread shaft 331 is restarted to make it rotate in the opposite direction. During the reverse rotation, all the clamping plates 32 move towards the large end of the gripper fixing member 31, and the straight segments 321 of all the clamping plates 32 move away from each other to release the linear workpiece and complete the flipping and handling of the linear workpiece. After the flipping and handling, the gripper mechanism 3 returns to the initial position to wait for the next flipping and handling. This cycle is repeated to ensure that the direction of each linear workpiece is consistent.

The cutting device and the flipping and conveying device are distributed sequentially according to a set processing sequence, that is, the flipping and conveying device and the cutting device are distributed in front of and behind each other.
