Description

Technical Field

[0001] The present invention relates to the technical field of laser processing, and specifically, to a laser processing device for rotary PDC cylindrical workpieces. Background Art

[0002] PDC is the English abbreviation of polycrystalline diamond compact. It is widely used in drilling tools in the oil extraction and geological drilling industries. One end of the cylindrical workpiece used in this type of drill bit is made of diamond material and has extremely high hardness, and the other end is made of metal material, which enables the workpiece to be welded. During the processing and feeding process of this workpiece, the commonly used feeding method is to use an independent manipulator to achieve automatic feeding. Using this method, first, the manipulator and the processing platform are two independent devices, and very high mechanical manufacturing accuracy and control accuracy are required to adjust the cooperation relationship between the manipulator and the processing platform to ensure meeting the processing accuracy. If the specifications of the processed parts change, a large amount of time is also required for adjustment. Setting up a manipulator operation platform beside the processing platform has a relatively high cost and will occupy a large amount of production space, thereby leading to a significant increase in the production time cost and equipment cost. Moreover, the manipulator operation platform needs to be specifically equipped with a storage tray for the manipulator to pick up and feed materials. In order to reduce the usage cost and reduce the space occupancy rate, a platform capable of automatic feeding is needed to solve this problem. Summary of the Invention

[0055] S2.

[0060] The working principle and beneficial effects of the present invention are as follows:

[0061] In the present invention, to solve the problems in the related art that in the laser processing of PDC cylindrical workpieces, a manipulator is required for automatic loading, resulting in high production costs and high space occupancy rates, a laser processing device for rotary PDC cylindrical workpieces is designed. Specifically, first, the cylindrical workpiece is placed in the feeding cavity. The storage channel in the feeding cavity can be arranged in an S-shaped spiral path to increase the internal capacity, and the S-shaped spiral path is a downward slope. The cylindrical workpiece can roll along the storage channel by its own gravity and roll into the feeding channel. The feeding channel also has a downward slope and rolls onto the receiving table surface of the second guiding slider. The receiving table surface of the second guiding slider is lower than the normal material outlet in the initial state, which can enable the cylindrical workpiece to stably enter the guiding gap. Subsequently, the first linear driving member drives the first guiding slider and the second guiding slider to approach each other. After the cylindrical workpiece is centered and they approach each other, the receiving table surface of the second guiding slider can be higher than the normal material outlet, so as to block the subsequent cylindrical workpieces. Then, the cylindrical workpiece is pushed into the clamping assembly by the push rod to realize the automatic loading of the cylindrical workpiece. Both the first guiding slider and the second guiding slider have V-shaped guiding grooves in the middle. The V-shaped guiding grooves can effectively receive the cylindrical workpiece and can adapt to the size of the cylindrical workpiece, enabling cylindrical workpieces of different specifications to be centered, which is convenient for the centering of the cylindrical workpiece. When the clamping assembly clamps the cylindrical workpiece, the PDC is processed by the laser processing device. After the processing is completed, the cylindrical workpiece is pushed out by the clamping device to continue processing the next workpiece.

[0062] Through this solution, the automatic loading function of the cylindrical workpiece can be realized without using a manipulator, and the cylindrical workpiece can be accurately positioned, ensuring the processing accuracy while reducing the equipment cost and the occupied space of the equipment.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0076] Embodiment 1

[0077] As Figures 1 to 10 shown, this embodiment proposes

[0078] a laser processing device for a rotary PDC cylindrical workpiece 7, including a frame 1 and a laser processing device 2 provided on the frame 1, and further including:

[0079] a mounting seat 3, the mounting seat 3 having a feeding channel 4,

[0080] a raceway type bin 5, provided on the frame 1, the raceway type bin 5 having a discharging cavity 6, the discharging cavity 6 communicating with the feeding channel 4, and the discharging cavity 6 being used for storing the cylindrical workpiece 7;

[0081] a clamping and guiding assembly 8, provided on the mounting seat 3, the clamping and guiding assembly 8 including:

[0082] a first linear driving member 9, provided on the mounting seat 3;

[0083] a first guiding slider 10 and a second guiding slider 11, both provided on the driving end of the first linear driving member 9, a guiding gap being formed between the two, the first linear driving member 9 being used for driving the first guiding slider 10 and the second guiding slider 11 to approach or move away from each other, and after the two move away from each other, the receiving table surface of the first guiding slider 10 is lower than the normal material outlet 12 of the feeding channel 4;

[0084] It further includes:

[0085] a clamping and positioning assembly 13, provided on the frame 1, the clamping and positioning assembly 13 including:

[0086] a clamping assembly 14, slidably provided on the frame 1, the clamping assembly 14 having a clamping end, and the guiding gap facing the clamping end;

[0087] a pusher assembly 15, provided on the mounting seat 3, having a push rod movably arranged in the guiding gap, and the push rod being used for pushing the cylindrical workpiece 7 into the clamping assembly 14.

[0088] In this embodiment, to solve the problems in the related art that a manipulator is required for automatic feeding during the laser processing of the PDC cylindrical workpiece 7, resulting in high production costs and high space occupancy, a laser processing device for the rotary PDC cylindrical workpiece 7 is designed. Specifically, first, the cylindrical workpiece 7 is placed into the feeding cavity 6. The storage channels in the feeding cavity 6 can be arranged in an S-shaped spiral path to increase the internal capacity. Moreover, the S-shaped spiral paths are all downward slopes. The cylindrical workpiece 7 can roll along the storage channels by its own gravity and roll into the feeding channel 4. The feeding channel 4 also has a downward slope and rolls onto the receiving table surface of the second guiding slider 11. The receiving table surface of the second guiding slider 11 is initially lower than the normal material outlet 12, which can enable the cylindrical workpiece 7 to stably enter the guiding gap. Subsequently, the first linear driving member 9 drives the first guiding slider 10 and the second guiding slider 11 to approach each other. After the cylindrical workpiece 7 is centered and they approach each other, the receiving table surface of the second guiding slider 11 can be higher than the normal material outlet 12, so as to block the subsequent cylindrical workpieces 7. Then, the cylindrical workpiece 7 is pushed into the clamping assembly 14 by a push rod to realize the automatic feeding of the cylindrical workpiece 7. Both the first guiding slider 10 and the second guiding slider 11 have V-shaped guiding grooves in the middle. The V-shaped guiding grooves can effectively receive the cylindrical workpiece 7 and can adapt to the size of the cylindrical workpiece 7, enabling cylindrical workpieces 7 of different specifications to be centered, which is convenient for the centering of the cylindrical workpiece 7. After the clamping assembly 14 clamps the cylindrical workpiece 7, the PDC is processed by the laser processing device 2. After the processing is completed, the cylindrical workpiece 7 is pushed out by the clamping device to continue processing the next workpiece.

[0089] Through this solution, the automatic feeding function of the cylindrical workpiece 7 can be realized without using a manipulator, and the cylindrical workpiece 7 can be accurately positioned, ensuring the processing accuracy while reducing the equipment cost and the occupied space of the equipment.

[0090] Furthermore, the feeding channel 4 has an inlet 16, and the roller-type storage bin 5 includes:

[0091] A feeding bin 17, the feeding cavity 6 is located on the feeding bin 17, the feeding bin 17 is slidably arranged on the frame 1, and there is a height difference between the discharge port 18 of the feeding bin 17 and the inlet 16;

[0092] A plugging member 19, which is slidably arranged on the roller-type storage bin 5. The plugging member 19 has a communication groove 20. After the plugging member 19 slides, the communication groove 20 communicates with the feeding channel 4 or the feeding bin 17;

[0093] A second linear driving member 21, which is arranged on the frame 1, and the second linear driving member 21 is used to drive the plugging member 19 to slide.

[0094] Furthermore, the raceway bin 5 is provided with a guiding groove 22 arranged in the vertical direction, and the plugging member 19 is slidably arranged in the guiding groove 22. The raceway bin 5 further includes:

[0095] A first elastic member 23, with one end arranged on the inner wall of the guiding groove 22 and the other end arranged on the plugging member 19, for providing a force for the plugging member 19 to slide in the guiding groove 22.

[0096] In this embodiment, in order to achieve intermittent feeding, avoid the accumulation of workpieces, and avoid affecting the subsequent positive and negative detection processes, a structure is provided. First, due to the height difference between the discharge port 18 and the inlet 16 of the discharge bin 17, the transition function of the plugging member 19 is realized. When the cylindrical workpiece 7 rolls into the communication groove 20 by its own gravity, the second linear driving member 21 drives the plugging member 19 to lift, so that the communication groove 20 communicates with the feeding channel 4, and the cylindrical workpiece 7 in the communication groove 20 enters the communication groove 20. Subsequently, the second linear driving member 21 drives the cylindrical workpiece 7 to descend again, so that the communication groove 20 communicates with the discharge port 18 of the discharge cavity 6, and the next cylindrical workpiece 7 enters the communication groove 20, preparing for lifting and feeding again, realizing the intermittent feeding of the cylindrical workpiece 7;

[0097] The telescopic end of the second linear driving device can be in contact with the bottom of the plugging member 19. For the convenience of replacing the plugging member 19, the second linear driving device only provides an upward acting force on the plugging member 19. When the second linear driving device contracts downward, the plugging member 19 falls downward due to gravity, and the first elastic member 23 can stretch to provide a partial upward acting force when the plugging member 19 moves downward, so that the plugging member 19 will not act too much on the second linear driving device and cause damage. When moving upward, it can also buffer the force of the top of the plugging member 19 acting on the inner wall of the guiding groove 22. At the same time, the first elastic member 23 can also increase the reset efficiency of the plugging member 19.

[0098] Furthermore, the middle part of the feeding channel 4 has a reverse material outlet 24 facing downward, and further includes a positive and negative screening assembly 25 arranged on the mounting seat 3. The positive and negative screening assembly 25 includes:

[0099] A detection assembly 26, arranged on the mounting seat 3, for detecting the positive and negative of the cylindrical workpiece 7;

[0100] A swinging member 27, swingably arranged on the mounting seat 3, for swinging to open or close the reverse material outlet 24.

[0101] In this embodiment, since one end of the cylindrical workpiece 7 is made of a metal material and the other end is a polycrystalline diamond composite sheet, and during laser processing, different powers have different processing effects on the metal material or the polycrystalline diamond composite sheet. If the power used for processing the polycrystalline diamond composite sheet is used to process the metal material, it will cause metal particles to splash and eventually damage the laser processing device 2. To avoid this situation, it is necessary to distinguish the front and back of the cylindrical workpiece 7. When the raw material is placed in the feeding bin 17, it is operated by an operator, and the front and back are distinguished at this moment. However, the operator may make a mistake and place the front and back wrongly, leading to an accident. In this solution, the detection component 26 detects the front and back of the cylindrical workpiece 7. After the detection, by judging the front and back, when it is positive, it directly enters the positive material outlet 12 through the swinging member 27. If it is negative, the swinging member 27 swings under the action of the rotation driving member, opens the reverse material outlet 24, and discharges the reverse cylindrical workpiece 7 through the reverse material outlet 24. After the discharge, the swinging member 27 resets to achieve positive and negative screening.

[0102] Further, the detection component 26 includes:

[0103] A stopper 28, slidably arranged on the mounting seat 3. After the stopper 28 slides, it extends into the feeding channel 4, and the stopper 28 is used to block the cylindrical workpiece 7;

[0104] A third linear driving member 29, arranged on the mounting seat 3, for driving the stopper 28 to slide;

[0105] A fourth linear driving member 30, arranged on the mounting seat 3;

[0106] A detection end 31, arranged on the driving end of the fourth linear driving member 30. The fourth linear driving member 30 drives the detection end 31 to move. After the detection end 31 moves, it approaches or moves away from the workpiece to be measured, and the detection end 31 is used to detect the magnetism of the cylindrical workpiece 7.

[0107] In this embodiment, a structure for positive and negative screening is specifically refined. Specifically, first, the third linear driving member 29 drives the stopper 28 to slide, so that the stopper 28 abuts on the channel where the cylindrical workpiece 7 rolls to block the cylindrical workpiece 7. Subsequently, the fourth linear driving member 30 drives the detection end 31 to move, so that the detection end 31 approaches the cylindrical workpiece 7. The detection end 31 is provided with a sensor for detecting magnetism. By judging the magnitude of the magnetism, the front and back are judged. After the detection, the swinging member 27 makes corresponding actions to realize the detection of the front and back. When the detection is completed, the third linear driving member 29 drives the stopper 28 to retract, so that the cylindrical workpiece 7 continues to roll and enters the positive material outlet 12 or the reverse material outlet 24 to complete the screening.

[0108] Further, the clamping component 14 includes:

[0109] A sliding seat 32, slidably arranged on the frame 1;

[0110] The clamping member 33 is rotatably arranged on the sliding seat 32. The clamping member 33 is used to connect with the driving motor 34. The clamping end is located on the clamping member 33. The clamping end has a clamping space 35 for clamping the cylindrical workpiece 7.

[0111] The first adjusting member 36 is arranged in the clamping space 35 with adjustable position.

[0112] The first sliding sleeve 37 has a sliding cavity. The first sliding sleeve 37 is slidably arranged on the first adjusting member 36 through the sliding cavity. The first sliding sleeve 37 is located in the clamping space 35. One end of the first sliding sleeve 37 is used to abut against the cylindrical workpiece 7.

[0113] The second elastic member 38 has one end arranged on the first adjusting member 36 and the other end arranged on the first sliding sleeve 37, and is used to provide a force for the first sliding sleeve 37 to push the cylindrical workpiece 7 away from the clamping space 35.

[0114] In this embodiment, in order to increase the position accuracy when clamping the cylindrical workpiece 7, a structure is designed. Specifically, first, the first adjusting member 36 is arranged in the clamping member 33. The first adjusting member 36 has a part with adjustable position. When the first sliding sleeve 37 slides on the first adjusting member 36 through the sliding cavity, it will be restricted by the first adjusting member 36. That is, when the first sliding sleeve 37 slides a certain distance on the first adjusting member 36 by an external force, the first adjusting member 36 will limit the first slideway. The sliding stroke of the first sliding sleeve 37 can be adjusted by adjusting the part on the first adjusting member 36 that limits the first slideway, and finally the purpose of controlling the processing position of the workpiece to be processed is achieved. When loading the workpiece by a manipulator or manually, by pushing the workpiece to be processed into the clamping space 35 and applying a force to push the workpiece to be processed, the workpiece to be processed slides into the clamping space 35. First, the workpiece to be processed abuts against the first sliding sleeve 37 and pushes the first sliding sleeve 37 to slide. When the first sliding sleeve 37 slides to the limit position, the clamping member 33 clamps the workpiece to be processed. The clamping member 33 can be a pneumatic chuck or a mechanical chuck for clamping. After clamping the workpiece to be processed, the driving motor 34 drives the clamping member 33 to rotate. When the processing is completed, the clamping member 33 releases the clamping of the workpiece to be processed. The second elastic member 38 located on the first sliding sleeve 37 and the first adjusting member 36 acts on the first sliding sleeve 37, causing the first sliding sleeve 37 to slide and pushing the workpiece to be processed out of the clamping space 35, completing one processing. By repeating the above steps, according to the present solution, the position of the limiting end on the first adjusting member 36 can be adjusted according to different specifications of the workpiece to be processed, so as to control the adjustment of the placement position of the workpiece to be processed, ensure the processing accuracy, and can realize the function of automatic unloading through the cooperation of the first sliding sleeve 37 and the first adjusting member 36.

[0115] Furthermore, the first adjusting member 36 includes:

[0116] The adjusting seat 39 is located within the clamping space 35 and has an adjusting space 40;

[0117] The first adjusting rod 41 is threadedly connected to the adjusting seat 39. After the first adjusting rod 41 rotates, it moves along the adjusting space 40. The first sliding sleeve 37 is slidably disposed on the first adjusting rod 41.

[0118] In this embodiment, the first adjusting member 36 is refined. Specifically, first, the first adjusting rod 41 is threadedly connected to the adjusting seat 39. After the first adjusting rod 41 rotates, the position of the first adjusting rod 41 can be adjusted, thereby adjusting the sliding position of the first sliding sleeve 37, and finally adjusting the placement position of the workpiece to achieve the purpose of adjustment.

[0119] Furthermore, the pusher assembly 15 includes:

[0120] The seventh linear driving member 59 is disposed on the mounting seat 3. The push rod is disposed on the seventh linear driving member 59. The push rod includes:

[0121] The second adjusting member 42 is disposed on the driving end of the seventh linear driving member 59 and has the same structure as the first adjusting member 36;

[0122] The second sliding sleeve 43 has the same structure as the first sliding sleeve 37 and is slidably disposed on the second adjusting member 42. One end of the second sliding sleeve 43 is used to abut against the cylindrical workpiece 7. After the seventh linear driving member 59 is driven, the second sliding sleeve 43 is used to push the cylindrical workpiece 7 towards the clamping member 33;

[0123] The third elastic member 44 has one end disposed on the second adjusting member 42 and the other end disposed on the second sliding sleeve 43, and is used to provide a force for the second sliding sleeve 43 to push the workpiece close to the clamping member 33.

[0124] In this embodiment, when machining the cylindrical workpiece 7, sometimes it is necessary to position based on the bottom of the workpiece, and sometimes it is necessary to position based on the machining end of the workpiece. Therefore, the pusher assembly 15 is designed to be able to assist in pushing the workpiece into the clamping space 35, and can clamp the workpiece at a suitable position after it enters the clamping space 35 by adjusting the second adjusting member 42, further ensuring the adaptability of the structure to adapt to different machining conditions.

[0125] Furthermore, the frame 1 has a slideway, and further includes a dust suction device 45. The dust suction device 45 includes:

[0126] The dust suction hood 46 is slidably disposed in the slideway and has a dust suction cavity. One end of the dust suction cavity has a dust removal port 47 for communicating with the dust suction machine, and the other end has an avoidance port 48 for semi-wrapping the cylindrical workpiece 7.

[0127] The lifting member 49 is arranged on the frame 1, and the dust suction hood 46 is arranged on the lifting member 49.

[0128] In this embodiment, during the laser processing of the laser processing equipment, dust and cracked particles will be generated. The dust will block the laser propagation and the cracked particles are likely to damage the protective lens. For this reason, a dust suction device 45 is designed. Specifically, an avoidance opening 48 is arranged at the top end of the dust suction hood 46. During the processing, the lifting member 49 drives the dust suction hood 46 to move up and down along the slideway. After rising, the clamping end and the raw material on the device are wrapped through the avoidance opening 48 on the dust suction hood 46, and the laser is used to process the raw material through the avoidance opening 48 to ensure the processing quality. The dust suction hood 46 can be composed of a top plate with a first avoidance opening, a side plate with a second avoidance opening, and a bottom plate with a bottom dust outlet. The top plate can be separated and replaced with the side plate and the bottom plate. The first avoidance opening and the second avoidance opening communicate with each other to jointly form the avoidance opening 48. Through this device, the raw material can be processed in the dust suction cavity. When dust is generated during the processing, the dust suction machine sucks air from the avoidance opening 48, so that the dust enters the dust suction machine from both sides of the dust suction hood 46 along with the wind force at the avoidance opening 48. The size of the avoidance opening 48 can be set so that the avoidance opening 48 is adapted to the size of the raw material fixture and the raw material, so that the wind force can better cover the raw material, thereby increasing the dust suction effect. At the same time, since the dust suction hood 46 wraps the raw material and only the avoidance opening 48 for laser processing is exposed, only a small part of the cracked particles generated during the laser processing shoot towards the protective lens from the direction of the avoidance opening 48, and other particles fall into the dust suction machine through the protection of the dust suction hood 46, avoiding the risk of the cracked particles colliding with the protective lens after bouncing around the protective lens, and increasing the service life of the protective lens.

[0129] Furthermore, it further includes a discharging mechanism 50. The discharging mechanism 50 includes:

[0130] The fifth linear driving member 51 is arranged on the mounting seat 3;

[0131] The discharging hopper 52 is arranged on the fifth linear driving member 51. The discharging hopper 52 has a discharging channel. The fifth linear driving member 51 is used to drive the inlet 53 of the discharging channel to approach or move away from the clamping end. The discharging direction of the discharging channel forms an angle with the vertical direction;

[0132] The finished product collection box 54 is arranged on the frame 1 and is located at the outlet of the discharging channel;

[0133] The pushing member 55 is slidably arranged on the mounting seat 3 and is located at the outlet of the discharging channel and has a guiding inclined surface 56;

[0134] The flexible buffer member 57 is arranged on the mounting seat 3 and is located at the outlet of the discharging channel. It encloses a buffer area with the guiding inclined surface 56. The buffer area is used to support the cylindrical workpiece 7;

[0135] The sixth linear driving member 58 is arranged on the mounting base 3 and is used to drive the pushing member 55 to slide. After sliding, it is used to unload the cylindrical workpiece 7 located in the buffer area.

[0136] In this embodiment, the cylindrical workpiece 7 is processed by laser. After the processing is completed, the clamping end releases the workpiece, allowing the workpiece to be sent out through the discharge channel. There is a processed cylindrical workpiece 7 at the discharge port 18. Since the material of the cylindrical workpiece 7 is hard, after the processing is completed, when it is discharged from the clamping end and falls, it has gravitational potential energy, resulting in a relatively fast falling speed. The relatively fast speed causes the just-fallen cylindrical workpiece 7 to collide with the already-fallen cylindrical workpiece 7. When two high-hardness workpieces collide, it is extremely easy to cause damage, resulting in workpiece damage and reducing product quality. To avoid this situation, a structure that can consume its kinetic energy is needed after it falls. First, it falls on the buffer area, and through the blocking of the flexible buffer member 57, its kinetic energy is consumed. After it is static, the sixth linear driving member 58 drives the pushing member 55, so that the cylindrical workpiece 7 crosses the flexible buffer member 57 and then enters the finished product collection box 54 through the guide inclined surface 56. Through this method, the workpiece defects caused by the collision between the cylindrical workpieces 7 can be effectively alleviated.

[0137] Furthermore, its processing method is as follows:

[0138] S1. Loading: The cylindrical workpieces 7 are sequentially loaded into the material placing cavity 6, and the cylindrical workpieces 7 roll down one by one due to their own gravity.

[0139] S2. Intermittent feeding: The cylindrical workpiece 7 rolls into the communication groove 20, and the second linear driving member 21 drives the blocking member 19 to rise. The communication groove 20 is communicated with the feeding channel 4, and the cylindrical workpiece 7 enters the feeding channel 4; at the same time, the second linear driving member 21 drives the blocking member 19 to descend, the communication groove 20 is communicated with the material placing bin 17, and the next cylindrical workpiece 7 enters the communication groove 20.

[0140] S3. Positive and negative detection: The third linear drive member 29 drives the blocking member 28 to move, blocking the rolling of the cylindrical workpiece 7 along the feeding channel 4. The fourth linear drive member 30 drives the detection end 31 to approach the blocked cylindrical workpiece 7. The magnetic detection member located on the detection end 31 detects the magnetic force on the end face of the cylindrical workpiece 7. By judging the strength of the magnetic force, the positive and negative are judged. When it is judged as positive, the swinging member 27 closes the reverse material outlet 24. The third linear drive member 29 drives the blocking member 28 to move, canceling the block of the cylindrical workpiece 7. The fourth linear drive member 30 drives the detection end 31 away from the cylindrical workpiece 7, and the cylindrical workpiece 7 continues to roll along the feeding channel 4. When it is judged as negative, the swinging member 27 opens the reverse material outlet 24. The third linear drive member 29 drives the blocking member 28 to move, canceling the block of the cylindrical workpiece 7. The fourth linear drive member 30 drives the detection end 31 away from the cylindrical workpiece 7, and the cylindrical workpiece 7 continues to roll along the feeding channel 4 and rolls into the reverse material outlet 24 and then enters the collection bin;

[0141] S4. Loading and clamping for processing: The cylindrical workpiece 7 rolls onto the receiving table surface of the first guiding slider 10. The first linear drive member 9 drives the first guiding slider 10 and the second guiding slider 11 to slide, centering the cylindrical workpiece 7 and blocking the subsequent cylindrical workpieces 7. The seventh linear drive member 59 drives the push rod to push the cylindrical workpiece 7 along the guiding gap towards the clamping end. At the same time, the sliding seat 32 drives the clamping member 33 to slide towards the guiding gap to receive the cylindrical workpiece 7. After the cylindrical workpiece 7 enters the clamping end, the clamping end clamps the cylindrical workpiece 7. After the sliding seat 32 adjusts its position, the laser processing device 2 is ready to process the cylindrical workpiece 7;

[0142] S5. Dust prevention during processing: After the cylindrical workpiece 7 is in place, the lifting member 49 drives the dust suction cover 46 to rise, and the dust suction cover 46 covers the cylindrical workpiece 7. The laser processing device 2 processes the cylindrical workpiece 7;

[0143] S6. Discharging: The lifting member 49 drives the dust suction cover 46 to descend. The fifth linear drive member 51 drives the discharging hopper 52 to approach the clamping end. The first sliding sleeve 37 pushes the cylindrical workpiece 7 out of the clamping space 35. The cylindrical workpiece 7 falls at the inlet 53 of the discharging hopper 52, enters the discharging channel, and rolls out from the outlet onto the guiding inclined plane 56. After the flexible buffer member 57 removes the impact force of the cylindrical workpiece 7, the sixth linear drive member 58 drives the pushing member 55 to drive the cylindrical workpiece 7 to slide over the flexible buffer member 57, and the cylindrical workpiece 7 rolls along the guiding inclined plane and falls into the finished product collection box 54.

[0144] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
