Description

Technical Field

[0001] This application relates to the field of laser microfabrication, and more particularly to a five-axis laser cutting machine for automatic loading and unloading of surgical instruments. Background Art

[0002] In the medical field, when an ultrasonic scalpel is processed, a laser cutting machine is usually used. Since such pipe fittings have a fixed length and processes such as mechanical flaring are performed at one end, the processing method of inserting the fixed-length pipe from one side of the rotating shaft and extending from the other side is damaged, resulting in the inability of traditional automatic loading machines to perform automatic loading and unloading of such pipe fittings, and manual loading and unloading is used for laser engraving processing.

[0003] In addition, since the pipe fitting is a rigid body, if the method of inserting by a manipulator is used, due to the problem of fitting tolerance, it is difficult for the manipulator to achieve high-precision fitting.

[0004] In view of this, those skilled in the art need to improve the loading system of the laser cutting machine for the above technical problems. Summary of the Utility Model

[0005] The main purpose of this application is to provide a five-axis laser cutting machine for automatic loading and unloading of surgical instruments, which realizes automatic loading of fixed-length pipes and has a high degree of automation.

[0006] To achieve the above object, in a first aspect, this application provides a five-axis laser cutting machine for automatic loading and unloading of surgical instruments, including a frame, a sorting bin arranged on the frame, a cutting head arranged on the frame, a pushing assembly for pushing a workpiece into the cutting head, and a transfer robotic arm assembly for transferring the workpiece from the sorting bin to the pushing module;

[0007] The pushing module includes a material-passing bracket assembly and a pushing assembly. The material-passing bracket assembly includes a left bracket and a right bracket that are relatively horizontally slidably arranged, a driving mechanism for driving the sliding of both the left bracket and the right bracket, and limiting grooves are provided on both the left bracket and the right bracket. When the left bracket and the right bracket are closed, the limiting grooves of the two form a limiting slideway that matches the workpiece.

[0008] Further improved, the pushing assembly includes a pushing frame fixedly arranged on the frame, a slide rail arranged on the pushing frame, a pushing plate slidably arranged on the slide rail, and a pushing cylinder for driving the sliding of the pushing plate.

[0009] Further improved, the driving mechanism is a double-acting cylinder.

[0010] Further improved, a conveyor belt is inclinedly arranged in the sorting bin. A push plate is slidably arranged at the lowest end of the conveyor belt. The push plate is driven to slide by a cylinder. The cross-sectional dimension of the push plate is larger than the dimension of one workpiece and smaller than the dimension of two workpieces. The pulley of the conveyor belt is driven to rotate by a motor. The sliding direction of the push plate is perpendicular to the conveying direction of the conveyor belt.

[0011] Further improved, it further includes a temporary storage rack with workpiece positioning grooves. A flipping conveying assembly for transferring the workpiece on the push plate to the temporary storage rack is arranged between the sorting bin and the temporary storage rack.

[0012] Further improved, the flipping conveying assembly includes a rotating shaft rotatably arranged on the frame and a first finger cylinder fixedly arranged on the rotating shaft. The rotating shaft is driven to rotate by a flipping driving mechanism.

[0013] Further improved, the flipping driving mechanism includes a pulley fixedly arranged on the rotating shaft, a driving motor, a driving wheel fixedly arranged on the motor shaft of the driving motor, and a driving belt arranged between the pulley and the driving wheel.

[0014] Further improved, the transfer robotic arm assembly includes a multi-axis robot and a second finger cylinder arranged on the multi-axis robot.

[0015] Compared with the prior art, the automatic loading and unloading five-axis laser cutting machine for surgical instruments provided by the present utility model has the beneficial effects that the transfer robotic arm assembly conveys the workpiece from the sorting bin to the threading bracket assembly, and the limiting slideway plays a guiding role for the workpiece. Moreover, the limiting slideway is coaxially arranged with the bushing and the chuck on the cutting machine. Then, the workpiece is pushed into the cutting machine along the limiting slideway by the pushing component, eliminating the need for manual loading and solving the problem of fitting tolerance caused by directly loading with a robotic arm, realizing automatic and precise loading.

[0029] Embodiment 1:

[0030] As Figure 1 - Figure 2 、 Figure 4 shown, an automatic loading and unloading five-axis laser cutting machine for surgical instruments includes a frame 1, a sorting bin 2 provided on the frame 1, a cutting head provided on the frame 1, a pushing assembly for pushing a workpiece into the cutting head, and a transfer robotic arm assembly for transferring the workpiece from the sorting bin 2 to the pushing module; the structure of the workpiece is as Figure 5 shown.

[0031] The pushing module includes a material-passing bracket assembly and a material-pushing assembly. The material-passing bracket assembly includes a left bracket 10 and a right bracket 11 that are relatively horizontally slidably arranged, and a driving mechanism 12 for driving the sliding of both the left bracket 10 and the right bracket 11. The driving mechanism 12 is a double-acting cylinder. Limiting grooves 13 are provided on both the left bracket 10 and the right bracket 11. When the left bracket 10 and the right bracket 11 are closed, the limiting grooves 13 of the two form a limiting slideway that cooperates with the workpiece.

[0032] The material-pushing assembly includes a material-pushing frame 14 fixedly provided on the frame 1, a slide rail 15 provided on the material-pushing frame 14, a material-pushing plate 16 slidably arranged on the slide rail 15, and a material-pushing cylinder for driving the sliding of the material-pushing plate 16.

[0033] Preferably, a conveyor belt 3 is inclinedly arranged in the sorting bin 2. A push plate 4 is slidably arranged at the lowest end of the conveyor belt 3. The push plate 4 is driven to slide by a cylinder. The cross-sectional dimension of the push plate 4 is larger than the size of one workpiece and smaller than the size of two workpieces. The pulley of the conveyor belt 3 is driven to rotate by a motor. The sliding direction of the push plate 4 is perpendicular to the conveying direction of the conveyor belt 3.

[0034] Working principle: The workpieces to be cut in batches are placed in the sorting bin 2. The inclined conveyor belt 3 of the sorting bin 2 drives the workpieces to roll continuously towards the inner side, ensuring that the workpieces can always be concentrated at the innermost side of the bin. At this time, the push plate 4 perpendicular to the conveyor belt 3 in the sorting bin 2 pushes upwards, only pushing out one workpiece. Then the manipulator moves to this position to clamp and transport the workpiece to the material-passing bracket assembly. The bracket closes to form a limiting slideway along the axis. The material-pushing assembly starts to push the material into the bushing and chuck with a coaxial relationship on the cutting machine (the reason for not directly using the manipulator to insert is that the pipe fitting is a rigid body. Based on the principle that two points form a straight line, so a flexible transmission method is adopted at this time. Because of the precision fit tolerance, it is difficult for the manipulator to achieve this precision, so this flexible pushing method is used to complete). At this time, the feeding is completed, and the cutting machine starts the automatic cutting process. After cutting is completed, another finished product gripper on the manipulator takes out the finished product and puts it into the finished product bin, and then repeats the above feeding process.

[0035] Embodiment 2: As Figure 3 shown, the difference from Embodiment 1 is that it further includes a temporary storage rack 7 with workpiece positioning grooves. A flipping conveyor assembly for transferring the workpiece on the push plate 4 to the temporary storage rack 7 is arranged between the sorting bin 2 and the temporary storage rack 7. The flipping conveyor assembly includes a rotating shaft 5 rotatably arranged on the frame 1, and a first finger cylinder 6 fixedly arranged on the rotating shaft 5. The rotating shaft 5 is driven to rotate by a flipping driving mechanism 12. The flipping driving mechanism 12 includes a pulley fixedly arranged on the rotating shaft 5, a driving motor, a driving wheel fixedly arranged on the motor shaft of the driving motor, and a driving belt arranged between the pulley and the driving wheel. The transfer manipulator assembly includes a multi-axis manipulator 8 and a second finger cylinder 9 arranged on the multi-axis manipulator 8.

[0036] Compared with Embodiment 1, in this embodiment, there are an additional temporary storage rack 7 and a flipping conveyor assembly. Therefore, the transfer manipulator assembly does not directly clamp the workpiece from the push plate 4, but clamps the workpiece on the temporary storage rack 7, and the flipping conveyor assembly is used to transport the workpiece on the push plate 4 to the temporary storage rack 7. Since the specifications of the workpieces are different during processing, especially the lengths are different, for the material-pushing assembly at this time, the control of its material-pushing cylinder is rather cumbersome. By setting the temporary storage rack 7, detection sensors can be arranged on it to detect the workpieces, thereby achieving the purpose of synchronously controlling the material-pushing assembly and simplifying the control logic of the material-pushing assembly.

[0037] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
