Description

Technical Field

[0001] This utility model relates to the field of sutures, and more specifically, to a drive device for a suture and a suture. Background Technology

[0002] Currently, most sewing machines use a suspension method where the sewing device is suspended from the light-guided beam track using an optical axis or other guiding structure. This method often has the following drawbacks: 1. Inconvenient operation: Because the suspension point is relatively high, grabbing and placing the sewing device is difficult, requiring a large range of arm movements; 2. Laborious operation, prone to sparse stitches. To avoid the rotating template, the suspension device is usually not suspended at the center of the drum, resulting in lateral forces generated by the balancer rope during sewing, making operation laborious and causing the sewing device to be unstable, easily leading to sparse stitches. Alternatively, some machines use a method where the sewing device is grabbed manually without a suspension device. This method also suffers from inconvenience and is time-consuming and laborious. The sewing device is usually placed on the machine housing at a distance, making it very inconvenient to retrieve and laborious to operate. A single sewing device weighs around 10KG, and without a suspension device, it is extremely strenuous to use, significantly affecting the sewing quality. Utility Model Content

[0003] The main objective of this invention is to provide a driving device and a stitcher for a stitcher, so as to solve the problem of time-consuming and labor-intensive operation of stitchers in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a driving device for a suture device is provided, comprising a first driving member, a sliding frame connected to a suspension device of the suture device, and a stop block. The first driving member has an output portion that can move laterally. The sliding frame is laterally movable. The stop block is movably connected to the sliding frame and has a driving position extending into the moving path of the output portion and a clearance position exiting the moving path of the output portion. When the stop block is in the driving position, the output portion is driven to engage with the sliding frame, and the output portion drives the sliding frame to move by pushing the stop block. When the stop block is in the clearance position, the output portion is driven to separate from the sliding frame, and the sliding frame can move bidirectionally relative to the output portion.

[0005] Furthermore, the stop includes a first stop and a second stop. Along the moving direction of the output section, the first stop and the second stop are located on both sides of the output section. The direction in which the first stop and the second stop are arranged sequentially is the first direction. When the sewing machine is sewing, the first stop is in the avoidance position, and the sliding frame moves along the first direction. After the sewing machine finishes sewing, the second stop is in the transmission position, and the output section drives the sliding frame to move along the first direction through the second stop.

[0006] Furthermore, the drive device also includes a second drive member and a third drive member. The second drive member is driven connected to the first stop and drives the first stop to move up and down. The third drive member is driven connected to the second stop and drives the second stop to move up and down.

[0007] Furthermore, the sliding frame has a mounting hole facing the output section, and the stop block is movably inserted into the mounting hole. The axial direction of the mounting hole forms an angle with the moving direction of the output section.

[0008] Furthermore, the output section has a connecting recess facing the stop block, and the stop block has a connecting protrusion facing the output section. When the stop block is in the driving position, the connecting recess and the connecting protrusion abut against each other; when the stop block is in the avoidance position, the connecting protrusion retracts from the connecting recess.

[0009] Furthermore, there are multiple stops, and the output part has multiple notches on the side facing the stops. The notches form connecting recesses. The arrangement direction of the stops and the arrangement direction of the notches are both along the moving direction of the output part, so that the notches on both sides of the output part cooperate with the stops on both sides respectively.

[0010] Furthermore, along the moving direction of the sliding frame, the length of the segment of the output section located between the stops is less than or equal to the distance between the stops.

[0011] According to another aspect of the present invention, a suture device is provided, including a frame and the aforementioned drive device for the suture device, wherein a first drive member of the drive device is disposed on the frame, and a sliding frame of the drive device is movably disposed on the frame.

[0012] Furthermore, the frame has a guide shaft that passes through a sliding frame of the drive unit, and the sliding frame moves along the extension direction of the guide shaft.

[0013] Furthermore, the drive unit also includes a ranging device, which is connected to the output of the drive unit or the sliding frame, and measures the moving distance of the sliding frame relative to the frame.

[0014] By applying the technical solution of this utility model, and through the movable connection between the stop block and the sliding frame, the sliding frame and the first driving component can flexibly switch between driving engagement and driving disengagement. This allows the first driving component to intermittently drive the sliding frame, enabling the first driving component to both drive the sliding frame synchronously and to drive it independently, allowing the sliding frame to move bidirectionally. This reduces the labor intensity of the operator and improves work efficiency. Simultaneously, the sliding frame can be moved under the drive of the first driving component to a position to avoid collisions with other moving parts, thus preventing collisions between the sewing machine and other moving parts and providing operating space for other components. Specifically, the sewing machine operates... When the first drive component moves the sliding frame to a predetermined position, the sliding frame can then be driven to separate from the first drive component. With the operator's assistance, the sliding frame can continue to move in the direction of movement of the first drive component, or it can move in the opposite direction of the direction of movement of the first drive component. Thus, regardless of whether the suturing direction is in the direction of movement of the first drive component or opposite to the direction of movement of the first drive component, the sliding frame can move independently of the first drive component in the suturing direction. This reduces the operator's workload and ensures the flexibility of the sliding frame's movement, thereby avoiding the operator from directly grasping and placing the suturing equipment and reducing the operator's arm movement range, thus reducing the operator's labor intensity.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0021] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0022] To address the problem of time-consuming and labor-intensive operation of existing suture devices, this invention provides a driving device and a suture device.

[0023] like Figure 1 The illustrated drive device for a suture includes a first drive member 10, a sliding frame 20 connected to the suspension device of the suture, and a stop block 30. The first drive member 10 has an output section 11 that can move laterally. The sliding frame 20 is laterally movable. The stop block 30 is movably connected to the sliding frame 20 and has a drive position that extends into the movement path of the output section 11 and a clearance position that exits the movement path of the output section 11. When the stop block 30 is in the drive position, the output section 11 is driven to engage with the sliding frame 20, and the output section 11 drives the sliding frame 20 to move by pushing the stop block 30. When the stop block 30 is in the clearance position, the output section 11 is driven to separate from the sliding frame 20, and the sliding frame 20 can move bidirectionally relative to the output section 11.

[0024] This embodiment, by setting a stop 30 and a movable connection between the sliding frame 20 and the first driving member 10, allows the sliding frame 20 and the first driving member 10 to flexibly switch between driving engagement and driving disengagement. This enables the first driving member 10 to intermittently drive the sliding frame 20, allowing the first driving member 10 to both drive the sliding frame 20 synchronously and drive it separately, enabling the sliding frame 20 to move independently of the first driving member 10 in both directions. This reduces the labor intensity of the operator and improves work efficiency. Simultaneously, the sliding frame 20 can also be moved under the drive of the first driving member 10 to a position to avoid collisions with other moving parts, thus preventing the suture machine from colliding with other moving parts and providing operating space for other components. Specifically, when the suture machine is working, the first... The driving component 10 drives the sliding frame 20 to a predetermined position. Then, the sliding frame 20 can be driven to separate from the first driving component 10. With the operation of the operator, the sliding frame 20 can continue to move in the direction of movement of the first driving component 10, or it can move in the opposite direction of movement of the first driving component 10. Thus, regardless of whether the suturing direction is in the direction of movement of the first driving component 10 or opposite to the direction of movement of the first driving component 10, the sliding frame 20 can move independently of the first driving component 10 in the suturing direction. This reduces the operator's workload and ensures the flexibility of the sliding frame 20's movement. It also avoids the operator from directly grabbing and placing the suturing equipment and reduces the operator's arm movement range, thereby reducing the operator's labor intensity.

[0025] It should be noted that this embodiment uses the driving device for sewing the curtain fabric by the sewing machine as an example. Depending on the actual situation, the driving device in this embodiment can also be used in other scenarios that require intermittent driving and bidirectional movement.

[0026] In this embodiment, the stop 30 includes a first stop 31 and a second stop 32. Along the moving direction of the output part 11, the first stop 31 and the second stop 32 are located on both sides of the output part 11. The direction in which the first stop 31 and the second stop 32 are arranged sequentially is the first direction. When the sewing machine is sewing, the first stop 31 is in the avoidance position, and the sliding frame 20 moves along the first direction. After the sewing machine finishes sewing, the second stop 32 is in the transmission position, and the output part 11 drives the sliding frame 20 to move along the first direction through the second stop 32. This allows the operator to freely operate the sliding frame 20 during the sewing process, and after the sewing is completed, the operator can drive the sliding frame 20 to move again by the first driving member 10. This reduces the difficulty of the operator's work and saves time and effort.

[0027] Specifically, such as Figure 1 As shown, in this embodiment, the stop 30 is located above the output section 11, in the first direction, that is... Figure 1From left to right, the first stop 31 and the second stop 32 are respectively located on the left and right sides of the output unit 11. When the first stop 31 descends to the transmission position and the second stop 32 rises to the clearance position, the output unit 11 can drive the sliding frame 20 to move to the left, and the sliding frame 20 can also move to the right independently of the first driving member 10; when the first stop 31 descends to the transmission position and the second stop 32 descends to the transmission position, the output unit 11 can drive the sliding frame 20 to move to the left or right; when the first stop 31 rises to the clearance position and the second stop 32 rises to the clearance position, the output unit 11 can drive the sliding frame 20 to move to the left or right. When block 32 rises to the clearance position, the sliding frame 20 can move independently to the left or right from the first drive member 10; when the first stop block 31 rises to the clearance position and the second stop block 32 falls to the transmission position, the first drive member 10 can drive the sliding member to move to the right, and the sliding frame 20 can also move independently to the left from the first drive member 10. In this way, through the setting of the first stop block 31 and the second stop block 32, the output unit 11 and the sliding frame 20 have four different working states, which can be flexibly adjusted, reducing the workload while meeting various driving requirements.

[0028] The driving device in this embodiment is applied to a suture machine. Through the cooperation of the stop 30 and the output part 11, the output part 11 can both drive the sliding part to move to a predetermined position along the first direction and drive the sliding frame 20 to move to the required position in the opposite direction of the first direction. Simultaneously, with the cooperation of the first stop 31 and the second stop 32, the sliding frame 20 can move independently of the first driving member 10 along the first direction to achieve suturing in the first direction, and it can also move independently of the first driving member 10 in the opposite direction to achieve suturing in the opposite direction. Thus, the driving device in this embodiment can meet the needs of both right-handed and left-handed operators, reducing labor intensity while improving the flexibility and adaptability of the driving device. It should be noted that the positions of the first stop 31 and the second stop 32 in this embodiment can be interchanged, still meeting the usage requirements of the sliding frame 20.

[0029] In this embodiment, the drive device further includes a second drive member and a third drive member. The second drive member is driven to the first stop 31 and drives the first stop 31 to move up and down. The third drive member is driven to the second stop 32 and drives the second stop 32 to move up and down, thereby realizing the automatic switching between the first stop 31 and the second stop 32 in the transmission position and the avoidance position, thus reducing the workload of the operator. In this embodiment, the second drive member only drives the first stop 31 to move up and down, and the third drive member only drives the second stop 32 to move up and down, thereby avoiding the need for the operator to manually switch the state of the stop 30, thus improving the safety of the drive device and improving work efficiency. Of course, the second drive member and the third drive member can also be linked, so that when the first stop 31 switches to the transmission position, the second stop 32 can switch to the avoidance position, and when the first stop 31 switches to the avoidance position, the second stop 32 can switch to the transmission position, which can meet the usage requirements and further improve the level of automation. Optionally, the second and third driving components can be cylinders. Of course, the second and third driving components can also adopt other driving structures, such as electric cylinders, servo motors, frequency converters, etc., as long as they meet the requirements.

[0030] In this embodiment, the sliding frame 20 has a mounting hole facing the output part 11, and the stop block 30 is movably inserted into the mounting hole. The axial direction of the mounting hole forms an angle with the moving direction of the output part 11, so that when the stop block 30 is in the transmission position, the sliding frame 20 and the output part 11 can be driven, and when the stop block 30 is in the avoidance position, it can avoid the movement path of the output part 11 to avoid interference with the output part 11 and damage. Specifically, in this embodiment, the sliding frame 20 is configured as a rectangular plate and is placed vertically. The sliding frame 20 has a mounting part that extends horizontally for mounting a stop block 30. The mounting part is provided with a mounting hole, and the stop block 30 is movably mounted in the mounting hole. Both the mounting part and the stop block 30 are positioned above the output part 11. Thus, when the output part 11 needs to drive the sliding frame 20 to move, the stop block 30 descends and abuts against the output part 11. When the output part 11 does not need to drive the sliding frame 20 to move, the stop block 30 rises to separate from the output part 11, thereby achieving flexible cooperation between the output part 11 and the sliding frame 20, thereby improving the flexibility of the drive device. In this embodiment, the mounting hole is axially aligned with the vertical direction, while the output part 11 moves horizontally. This achieves the cooperation between the stop block 30 and the output part 11 while avoiding interference between the output part 11 and the stop block 30. Of course, the axial direction of the mounting hole and the moving direction of the output part 11 do not necessarily have to be perpendicular. Depending on actual needs or space limitations, the axial direction of the mounting hole and the moving direction of the output part 11 can also form an acute angle, an obtuse angle, etc., as long as the stop block 30 can avoid the movement path of the output part 11 when it is in the avoidance position.

[0031] In this embodiment, the output part 11 has a connecting recess 111 facing the stop block 30, and the stop block 30 has a connecting protrusion 311 facing the output part 11. When the stop block 30 is in the driving position, the connecting recess 111 and the connecting protrusion 311 abut against each other; when the stop block 30 is in the avoidance position, the connecting protrusion 311 retracts from the connecting recess 111, thereby realizing the drive docking and drive separation between the output part 11 and the stop block 30. Specifically, in this embodiment, the stop block 30 is a columnar structure that is vertically placed in the mounting hole of the sliding frame 20. The connecting recess 111 is located at the top of the output part 11 and below the mounting hole, with the opening of the connecting recess 111 facing upward to facilitate cooperation with the connecting protrusion 311. The stop block 30 is configured with a first segment and a second segment. The first segment is a square column located within a square mounting hole to prevent rotation of the stop block 30 within the mounting hole, thereby improving the safety of the drive device. The second segment of the stop block 30 is closer to the output section 11 than the first segment. The second segment is a circular column to facilitate engagement with the connecting recess 111 of the output section 11. The first segment is a hollow square column, and the second segment is movably connected to the first segment as a connecting protrusion 311. The second segment is coaxial with the first segment, and the outer diameter of the second segment is smaller than the side length of the cross-section of the first segment. When the second segment rises, it can retract into the first segment, allowing the stop block 30 to be in a clearance position and exit the connecting recess 111. The second segment can also descend relative to the first segment to the transmission position, thereby abutting the connecting recess 111. Of course, the structure of the stop block 30 is not limited to this and can be adjusted according to actual needs to flexibly achieve drive separation and drive docking between the output section 11 and the stop block 30.

[0032] In this embodiment, there are multiple stop blocks 30, and the output part 11 has multiple notches on its side facing the stop blocks 30. The notches form connecting recesses 111. The arrangement direction of the stop blocks 30 and the arrangement direction of the notches are both along the moving direction of the output part 11, so that the notches on both sides of the output part 11 respectively cooperate with the stop blocks 30 on both sides. Specifically, in this embodiment, the side of the output part 11 facing the stop blocks 30, which is the upper surface of the output part 11, has a notch on each of its left and right edges. The mounting holes of the sliding frame 20 above the output part 11 are also set to two, and a stop block 30 is set in each mounting hole. The notch is aligned with the mounting hole along the height direction, so that when the stop block 30 located inside the mounting hole descends, it can extend into the notch, thereby realizing the driving docking of the output part 11 and the sliding frame 20. When the stop block 30 rises, the second segment near the output part 11 retracts to the first segment, thus being higher than the upper surface of the output part 11, so that the output part 11 can move horizontally without interfering with the stop block 30.

[0033] In this embodiment, along the moving direction of the sliding frame 20, the length of the segment of the output part 11 located between the stops 30 is less than or equal to the distance between the stops 30, so that when the stops 30 are lowered to the transmission position, the output part 11 can move to abut against the stops 30, thereby driving the sliding frame 20 to move. Specifically, in this embodiment, the segment of the output section 11 located between the stops 30, that is, the distance between the two notches of the output section 11 along the first direction, is less than or equal to the distance between the stops 30. This ensures that when the first stop 31 located on the left descends to the transmission position, it can be located at the left notch or to the left of the left notch, but not to the right of the left notch. This ensures that when the output section 11 moves to the left, the connecting protrusion 311 of the first stop 31 and the connecting recess 111 on the left side of the output section 11 can abut. Even if the first stop 31 fails to abut the connecting recess 111 when it descends, it can still abut the connecting recess 111 as the output section 11 moves to the left. This allows the output section 11 to drive the sliding frame 20 to move synchronously. Similarly, when the second stop 32 located on the right descends to the transmission position, it will not be located to the left of the right notch. This ensures that when the output section 11 moves to the right, it can drive the sliding frame 20 to move synchronously to the right, thus ensuring the reliability of the synchronous movement of the output section 11 and the sliding frame 20. In this embodiment, the segment of the output section 11 between the stops 30 is equal to the distance between the stops 30. Thus, when the output section 11 and the sliding frame 20 are aligned in the height direction, the first stop 31 can descend to the left notch when it descends, and the second stop 32 can descend to the right notch when it descends.

[0034] This embodiment also provides a suture device, including a frame 40 and the aforementioned drive device for the suture device. A first drive member 10 of the drive device is mounted on the frame 40, and a sliding frame 20 of the drive device is movably mounted on the frame 40. In this embodiment, the first drive member 10 is a rodless cylinder. The first drive member 10 is positioned along a first direction, with its two ends fixed to the frame 40. The output section 11 can reciprocate along the first direction. The sliding frame 20 is located above the first drive member 10, facilitating the engagement of the stop block 30 with the output section 11 during lifting and lowering. Alternatively, the sliding frame 20 can be positioned below the output section 11, allowing the stop block 30 to extend upwards to engage with the output section 11 and retract downwards to separate from it. The first drive member 10 can also employ other drive structures such as a servo motor or a variable frequency motor, enabling the output section 11 to reciprocate along the first direction.

[0035] In this embodiment, the frame 40 has a guide shaft 41, which passes through the sliding frame 20 of the drive device. The sliding frame 20 moves along the extending direction of the guide shaft 41, thereby providing guidance for the movement of the sliding frame 20. In this embodiment, the guide shaft 41 is cylindrical and extends along a first direction. The sliding frame 20 has a guide hole extending along the first direction, and the guide shaft 41 passes through the guide hole to guide the sliding frame 20, thereby improving the stability and accuracy of the movement of the sliding frame 20, thus improving the stability and accuracy of the suture device, and thus improving the suture quality. Optionally, the guide shaft 41 can be a light shaft, a guide rail, or a pulley, as long as it can achieve the guiding function.

[0036] In this embodiment, the driving device also includes a ranging device, which is connected to the output part 11 of the driving device or the sliding frame 20, and measures the moving distance of the sliding frame 20 relative to the frame 40, so that the sliding frame 20 can move to a predetermined position and stop, so as to facilitate the sewing operation of the sewing machine, thereby achieving accurate judgment of the sewing position and improving the sewing quality.

[0037] The movement process of the drive device for the suture in this embodiment is as follows: 1. The initial positions of the sliding frame 20 and the first drive member 10 are both located at... Figure 1 1. The right end of the middle frame 40 is positioned to avoid other components; 2. The first stop 31 is lowered to the transmission position, and the second stop 32 is raised to the avoidance position. Then, the first drive unit 10 is activated, and the output part 11 of the first drive unit 10 drives the sliding frame 20 to move from right to left through the first stop 31. 3. The sliding frame 20 follows the first drive unit 10 to the leftmost waiting position of the frame 40. The movement speed can be controlled by the pressure of the rodless cylinder. 4. When the operator performs the sewing operation, the second stop 32 is driven to fall to the transmission position, and the first stop 31 is raised to the avoidance position. The output part 11 pushes the sliding frame 20 to the right through the second stop 32. When it reaches the position suitable for the operator to pick up, the sliding frame 20 begins to move independently of the first drive unit 10 from left to right, while the output part 11 stops moving and waits in place for the operator to pick it up. The stopping position of the output part 11 is measured by a distance measuring device. 5. After stitching is completed, the output unit 11 moves to the right, pushing the sliding frame 20 to its initial position on the right side of the frame 40, awaiting the next cycle. Of course, the above only describes the movement process of the drive device when stitching from left to right; the movement process of each component of the drive device when stitching from right to left can be mirrored.

[0038] It should be noted that "multiple" in the above embodiments refers to at least two.

[0039] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0040] 1. It solves the problem of time-consuming and labor-intensive operation of existing suture devices;

[0041] 2. By setting a stop block and a movable connection between the sliding frame and the first drive component, the sliding frame and the first drive component can be flexibly switched between drive docking and drive separation. This enables the first drive component to intermittently drive the sliding frame, allowing the first drive component to both drive the sliding frame synchronously and drive it separately, enabling the sliding frame to move independently of the first drive component in both directions. This reduces the labor intensity of the operator and improves work efficiency.

[0042] 3. The sliding frame can also move to a position to avoid other moving parts under the drive of the first drive component, thereby avoiding collisions between the sewing machine and other moving parts and leaving operating space for other parts.
