Description

Technical Field

[0001] This invention relates to the technical field of drilling and cutting, and specifically to a drilling and cutting machine for door and window frames. Background Technology

[0002] The processing of door and window profiles typically involves drilling and cutting long strips of profiles sequentially, ultimately assembling them into the required frame structure. In actual production, the profile processing flow largely relies on manual operation: operators first move the profiles to the processing station, then manually stabilize the profiles for drilling; after drilling, the profiles are manually adjusted and cut; finally, the cut profiles are manually moved to the collection area.

[0003] However, this traditional processing method has many shortcomings: on the one hand, the whole process is highly dependent on manual labor, resulting in high labor costs and low production efficiency; on the other hand, during drilling and cutting, operators need to support the profiles at close range, which poses a significant safety hazard. Summary of the Invention

[0004] The present invention aims to provide a door and window frame drilling and cutting machine that can reduce manual operation in the production process, thereby reducing labor costs, improving production efficiency, and reducing safety hazards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: 1) A door and window frame drilling and cutting machine, comprising a frame, wherein the frame is sequentially provided with a first conveying and moving structure for clamping and conveying the profile to be processed, a processing structure for processing the profile and having the function of clamping and moving the profile, and a second conveying and moving structure for moving and conveying the processed profile, wherein the processing structure includes a drilling unit for drilling the profile and being movable, a first moving unit for clamping and moving the profile, and a cutting unit for cutting the drilled profile and being movable, which are sequentially arranged on the frame; The first moving unit includes a movable seat mounted on a frame, on which a support roller for supporting the profile is rotatably connected. The movable seat is provided with a first clamping group for clamping the profile. The first clamping group includes a fixed clamping column and a movable clamping column rotatably mounted on the movable seat. The movable clamping column can move toward or away from the fixed clamping column. The movable seat is rotatably provided with a lower pressure roller for limiting the top of the profile and which can move up and down. The lower pressure roller is located above the support roller.

[0006] In this invention, the profile to be processed is placed on a first conveying moving structure. The first conveying moving structure can clamp the profile to be processed and convey it to the support roller of the first moving unit. At this time, the profile is located between the fixed clamping column and the moving clamping column. The moving clamping column moves towards the profile. During the movement, the moving clamping column contacts the profile and pushes the profile towards the fixed clamping column until the side of the profile away from the moving clamping column contacts the fixed clamping column. At this time, the fixed clamping column and the moving clamping column clamp the profile together, thereby reducing the profile from moving to both sides. The lower pressure roller moves towards the profile until the lower pressure roller contacts the top of the profile. The lower pressure roller limits the profile in the height direction, further reducing the displacement of the profile, thereby improving the stability of the profile. In the subsequent drilling operation, the moving clamping column, the fixed clamping column and the lower pressure roller can respectively limit the movement of the profile to both sides and upwards, thereby improving the stability of the profile.

[0007] After the profile is limited, the first conveying moving structure continues to move the profile to be processed, while the moving seat moves synchronously with the profile to be processed in a direction away from the drilling unit; at the same time, the drilling unit moves until the hole to be processed on the profile corresponds to the drilling unit, and then the drilling operation begins.

[0008] After completing the drilling operation at the aforementioned drilling positions, the first conveying and moving structure continues to move the profile until the subsequent drilling positions correspond to the drilling unit, at which point the drilling unit begins the drilling operation. The cutting unit moves to the position on the profile that needs to be cut, and the cutting unit performs the cutting operation on the profile, thus completing the drilling and cutting of a section of the profile. The above operation is repeated to complete the subsequent drilling and cutting operations on the profile. During the movement of the profile, since the moving and fixed clamping columns are in contact with both sides of the profile, the moving and fixed clamping columns can rotate along with the profile, thereby reducing the friction between the moving and fixed clamping columns and the profile, and thus reducing wear on the profile.

[0009] During the above operation, the support roller, fixed clamping column, movable clamping column and lower pressure roller are all rotatably connected to the moving seat. During the process of the first conveying moving structure driving the profile to move, the support roller, fixed clamping column, movable clamping column and lower pressure roller can rotate with the movement of the profile, thereby reducing the friction between the profile and the support roller, fixed clamping column, movable clamping column and lower pressure roller, and thus reducing the scratches on the profile.

[0010] After the drilling and cutting operations are completed, the second conveying and moving structure moves the drilled and cut profiles and transports them to a unified collection location. This invention sequentially uses the first conveying and moving structure to transport the profiles to be processed between the fixed and movable clamping columns of the mounting base; the fixed and movable clamping columns and the lower pressure roller clamp the profiles; the drilling and cutting units perform drilling and cutting operations on the profiles; and the second conveying and moving structure moves the drilled and cut profiles to the collection location. This reduces manual operation during profile processing, thereby reducing labor costs and improving overall production efficiency. During the drilling and cutting operations, the profiles are clamped by the first conveying and moving structure and limited by the support rollers, fixed clamping columns, movable clamping columns, and lower pressure rollers, which improves the stability of the profiles and reduces the need for operators to closely support the profiles during drilling and cutting, thus improving safety during production.

[0011] According to 1), a door and window frame drilling and cutting machine is provided, wherein: A first linear motor is fixedly mounted on the frame. The sliding table of the first linear motor is fixedly connected to the moving base. The first linear motor is fixedly connected to the moving base. The fixed clamping column is rotatably connected to the moving base. The sliding table of the first linear motor is rotatably connected to the moving clamping column. Both the fixed clamping column and the moving clamping column are vertically arranged. A second linear motor is fixedly connected to one side of the moving base. The moving direction of the sliding table of the second linear motor is perpendicular to the moving direction of the sliding table of the first linear motor. A moving rod is fixedly connected to the sliding table of the second linear motor. A pressing cylinder is fixedly connected to the top of the moving rod. The output shaft of the pressing cylinder is rotatably connected to a pressing roller. The pressing roller is horizontally arranged.

[0012] In this invention, when the first conveying moving structure drives the profile to move towards the moving seat, both the punching unit and the moving seat move towards the first conveying moving structure. When the profile moves onto the support roller of the moving seat, the profile is located between the fixed clamping column and the moving clamping column. The first moving linear motor is started, driving the moving clamping column, which is rotatably connected to the moving slide of the first moving linear motor, to move towards the profile. During the movement, the moving clamping column contacts the profile and pushes the profile towards the fixed clamping column until the side of the profile away from the moving clamping column contacts the fixed clamping column. The first moving linear motor stops running, and the moving clamping column and the fixed clamping column together clamp the profile to limit its position.

[0013] The second linear motor is started, driving the moving rod to move closer to the profile until the lower pressure roller is above the profile, at which point the second linear motor stops. The lower pressure cylinder is then started, driving the lower pressure roller to move closer to the profile until the lower pressure roller contacts the top of the profile, at which point the lower pressure cylinder stops. The lower pressure roller then limits the profile in the height direction. After the profile is clamped and limited, its stability is improved. During subsequent drilling operations, the moving clamping column, the fixed clamping column, and the lower pressure roller can respectively limit the profile's movement to the sides and upwards, thereby improving the profile's stability.

[0014] After the support roller, fixed clamping column, moving clamping column, and lower pressure roller limit the profile, the first conveying moving structure continues to drive the profile to move. At the same time, the first linear motor starts, causing the moving seat to move synchronously with the profile away from the punching unit. Moving the punching unit moving seat in the above manner can shorten the distance that the profile needs to move to the support roller of the moving seat, thereby reducing the instability of the profile due to excessive moving distance. Meanwhile, the punching unit moves until the hole to be processed on the profile corresponds to the punching unit. The second linear motor stops running, the punching unit stops moving, and then the punching machine starts the punching operation.

[0015] During the movement of the profile, the moving clamping column and the fixed clamping column are in contact with the two sides of the profile, and the lower pressure roller is in contact with the top of the profile. Therefore, as the profile moves, the moving clamping column, the fixed clamping column and the lower pressure roller can be driven to rotate, thereby reducing the friction between the moving clamping column, the fixed clamping column and the lower pressure roller and the profile, and thus reducing the wear on the profile.

[0016] According to 1), a door and window frame drilling and cutting machine is provided, wherein: The first conveying and moving structure includes a first conveying unit for conveying the profile to be processed, a receiving and clamping unit for receiving and holding the profile to be processed, and a second moving unit for clamping and moving the profile to be processed. The first conveying unit includes a plurality of first synchronous conveyor belts fixedly mounted on the frame. All the first synchronous conveyor belts are parallel to each other and spaced apart. The receiving and clamping unit includes several first movable cylinders fixedly mounted on a frame. The output shaft of each first movable cylinder is fixedly connected to a first connecting block. The ends of all first connecting blocks away from the first movable cylinders are connected to a long strip-shaped first movable plate. Several first receiving rollers for receiving profiles conveyed by the first conveying unit are rotatably connected to one side of the first movable plate. The first receiving rollers are horizontally arranged. Several positioning rollers for limiting the profiles are rotatably connected to the top of the first movable plate. The positioning rollers are vertically arranged. The side of the first movable plate away from the first movable cylinders faces the end of the first synchronous conveyor belt. The first receiving rollers face the first synchronous conveyor belt, and each first receiving roller is located between adjacent first synchronous conveyor belts. The first movable plate is provided with a top clamping unit for pressing on the top of the profile and rotatable, and two side clamping units for clamping the sides of the profile and rotatable.

[0017] In this invention, the first moving cylinder is activated to drive the first connecting block to move upward. As the first connecting block moves, it can drive the first moving plate to move upward. As the first moving plate moves, it can drive a plurality of first receiving rollers on it to move upward.

[0018] Since each first receiving roller is located between adjacent first synchronous conveyor belts, as the first receiving roller moves upward, it will contact the bottom of the profile on the first synchronous conveyor belt, and the positioning roller will contact one side of the profile. The positioning roller can limit the profile. The first receiving roller continues to move upward to above the first synchronous conveyor belt, and the first receiving roller can push the profile to move to above the first synchronous conveyor belt. At this time, the profile is on the first receiving roller, and the first moving cylinder stops running.

[0019] After the profile is placed on the first receiving roller, the top clamping unit limits the top of the profile, and the two side clamping units clamp and position the two sides of the profile, which can reduce the movement of the profile, improve the stability of the profile, and facilitate the subsequent clamping of the profile by the second moving unit.

[0020] According to 3), a door and window frame drilling and cutting machine is provided, wherein: The second moving unit includes a second linear motor fixedly mounted on a frame. A clamping rod is fixedly connected to the moving slide of the second linear motor. An installation cylinder is fixedly connected to the end of the clamping rod. A clamping cylinder is fixedly installed inside the clamping cylinder. Two first connecting rods are hinged to the free end of the output shaft of the clamping cylinder. A second connecting rod is hinged to the end of the first connecting rod away from the clamping cylinder. The end of the second connecting rod away from the first connecting rod is rotatably connected to the wall of the installation cylinder. Clamping fingers are fixedly connected to the sides of the two second connecting rods that are far apart from each other.

[0021] In this invention, after the profile is positioned on the first receiving roller and the top clamping unit limits the top of the profile, and the two side clamping units clamp and position the sides of the profile, the second linear motor is started to drive the clamping rod to move towards the end of the profile until the end of the profile is between the two clamping fingers, at which point the second linear motor stops running. The clamping cylinder is then started, driving the ends of the two first connecting rods hinged to the output shaft of the clamping cylinder to move away from the clamping cylinder, causing the other ends of the two first connecting rods to move away from each other. This pushes the ends of the two second connecting rods hinged to the first connecting rods to move away from each other. Since the other ends of the second connecting rods are rotatably connected to the mounting cylinder, the ends of the two second connecting rods away from the first connecting rods will move towards each other, thereby driving the two clamping fingers to move closer together until the clamping fingers abut against the sides of the profile. At this point, the two clamping fingers jointly clamp the profile, and the clamping cylinder stops running. The second linear motor is then started to drive the clamping rod and the profile to move towards the processing structure until the profile is positioned on the supporting roller, at which point the second linear motor stops running.

[0022] After all the required cutting positions of the profile are completed, the clamping cylinder is activated, driving the ends of the two first connecting rods that are hinged to the output shaft of the clamping cylinder to move closer to the clamping cylinder. The other ends of the two first connecting rods move closer to each other, thereby causing the ends of the two second connecting rods that are hinged to the first connecting rods to move closer to each other. The ends of the two second connecting rods that are away from the first connecting rods will move away from each other, thereby causing the two clamping fingers to move away from each other until the two clamping fingers separate from the profile, and the clamping cylinder stops operating.

[0023] According to 3), a door and window frame drilling and cutting machine is provided, wherein: The top clamping unit includes several transverse linear motors spaced apart on the side of the first moving plate away from the first synchronous conveyor belt. One end of the fixed slide rail of the transverse linear motor is fixedly connected to the first moving plate. A vertical linear motor extending upward is fixedly connected to the moving slide of the transverse linear motor. A top clamping roller extending towards the first synchronous conveyor belt is rotatably connected to the moving slide of the vertical linear motor.

[0024] In this invention, when the profile is located on the first receiving roller, the horizontal linear motor is started, driving the vertical linear motor to move closer to the profile until the top clamping roller is above the profile, at which point the horizontal linear motor stops running; the vertical linear motor is then started, driving the top clamping roller to move downwards until the bottom of the top clamping roller contacts the top of the profile, at which point the vertical linear motor stops running. At this point, the top clamping roller limits the profile in the height direction, and then the clamping units on both sides clamp and limit the profile on both sides. The top clamping roller and the moving slide of the vertical linear motor are rotatably connected. During the movement of the profile, the top clamping roller can rotate accordingly, thereby reducing the friction between the profile and the top clamping roller during the movement of the profile, and thus reducing the wear of the profile by the top clamping roller.

[0025] After the support roller, fixed clamping column, moving clamping column, and lower pressure roller clamp and limit the profile, the vertical linear motor is started to drive the top clamping roller to move upward until it separates from the profile. The vertical linear motor then stops running. Subsequently, the horizontal linear motor is started to drive the vertical linear motor to move away from the profile. The clamping units on both sides release their clamping on the profile, which can avoid friction between the top clamping roller and the clamping units on the profile during subsequent profile movement.

[0026] According to 3), a door and window frame drilling and cutting machine is provided, wherein: The two-sided clamping unit includes several second clamping groups. Each second clamping group includes two movable clamping columns that can move relative to each other. The two movable clamping columns are located on both sides of the first movable plate and are arranged in a one-to-one correspondence. The first movable plate is provided with several side linear motors that correspond one-to-one with the movable clamping columns. The fixed slide rail of the side linear motor is fixedly connected to the first movable plate, and the movable slide of the side linear motor is rotatably connected to the bottom of the movable clamping column.

[0027] In this invention, after the top clamping roller contacts the top of the profile, the side linear motor is activated, driving the two movable clamping columns to move in a closer direction until the two movable clamping columns contact both sides of the profile. The side linear motor then stops. During subsequent drilling operations, the two movable clamping columns and the top clamping roller can respectively restrict the profile's movement to the sides and upwards, thereby improving the profile's stability. The second moving unit clamps the profile and moves it onto the support roller. Subsequently, the fixed clamping column, the movable clamping column, and the lower pressure roller clamp the profile. During the profile's movement, the movable clamping columns on both sides of the profile can limit its movement, thereby improving the profile's stability.

[0028] During the profile movement, since the two movable clamping columns are in contact with both sides of the profile, their movement causes them to rotate, reducing friction between the clamping columns and the profile, and thus minimizing wear. After the fixed clamping column, movable clamping column, and lower pressure roller clamp the profile, the side linear motor is activated to drive the movable clamping columns away from the profile, preventing further friction during subsequent profile movement.

[0029] According to 1), a door and window frame drilling and cutting machine is provided, wherein: The punching unit includes a first punching linear motor fixedly mounted on a frame, located below a first receiving roller. A punching bracket is fixedly connected to the moving slide of the first punching linear motor, and a sliding plate is slidably connected to the punching bracket. A servo motor is fixedly connected to the top of the sliding bracket, and a downwardly extending lead screw is fixedly connected to the output shaft of the servo motor. The lead screw is threadedly connected to the sliding plate. A second punching linear motor is fixedly connected to the sliding plate. The moving direction of the moving slide of the second punching linear motor is perpendicular to the moving direction of the moving slide of the first punching linear motor. A punching machine is fixedly connected to the moving slide of the second punching linear motor. The cutting unit includes a cutting linear motor fixedly mounted on a frame, a cutting bracket fixedly connected to the moving slide of the cutting linear motor, and a cutting machine fixedly connected to the cutting bracket.

[0030] In this invention, activating the first drilling linear motor drives the drilling bracket to move, which in turn moves the drilling machine along the profile axis. Activating the servo motor drives the lead screw to rotate, causing the sliding plate to move downwards along the lead screw, thus moving the drilling machine along the height direction. Activating the second drilling linear motor drives the drilling machine to move perpendicular to the profile axis. By using the first, servo, and second drilling linear motors to drive the drilling machine, it can be moved to the desired drilling position on the profile. Activating the first cutting linear motor drives the cutting bracket to move, which in turn moves the cutting machine along the profile axis, thus moving the cutting machine to the desired cutting position on the profile.

[0031] According to 1), a door and window frame drilling and cutting machine is provided, wherein: The second conveying and moving structure includes a third moving unit for clamping and moving the cut profile and a second conveying unit for receiving and conveying the cut profile. The third moving unit includes a third linear motor fixedly mounted on the frame, located above the second conveying unit. An inverted U-shaped mounting frame is fixedly connected to the moving slide of the third linear motor. A fixed plate is fixedly connected to the inner wall of the mounting frame. A sliding frame and a mounting plate are sequentially fixedly connected to the side of the mounting frame away from the fixed plate. A conveying cylinder is hinged to the mounting plate. A push rod is hinged to the output shaft of the conveying cylinder. The push rod is slidably connected to the sliding frame. A movable plate is hinged to the end of the push rod away from the conveying cylinder. The position of the movable plate corresponds to the position of the fixed plate. A channel for the profile to enter is formed between the movable plate and the fixed plate.

[0032] In this invention, when the cutting machine moves to a position corresponding to the location where the profile needs to be cut, the third linear motor is activated, driving the mounting frame to move above the profile and position the profile between the movable plate and the fixed plate. The third linear motor then stops running. Subsequently, the cutting machine performs the cutting operation on the profile. After the cutting operation is completed, the conveying cylinder is activated, driving the push rod and the movable plate to move closer to the profile until the movable plate abuts against the profile. The conveying cylinder then stops running, at which point the movable plate and the fixed plate together clamp the cut profile. After the movable plate and the fixed plate clamp the cut profile on both sides, the third linear motor is activated, driving the mounting frame and the profile to move onto the second conveying unit, which then moves it to a unified collection position.

[0033] According to 8), a door and window frame drilling and cutting machine is provided, wherein: The second conveying unit includes a second moving plate that can move up and down and is elongated in shape. The frame is provided with a plurality of second moving cylinders. The output shaft of the second moving cylinder is fixedly connected to a second connecting block. The end of the second connecting block away from the second moving cylinder is fixedly connected to one side of the second moving plate. The second moving plate is connected with a plurality of second receiving rollers that are spaced apart and used to receive profiles. The second conveying unit also includes a plurality of second synchronous conveyor belts that are parallel to each other and spaced apart. The second synchronous conveyor belts are fixedly connected to the frame. The second receiving rollers are arranged facing the second synchronous conveyor belts, and each second receiving roller is located between adjacent second synchronous conveyor belts.

[0034] In this invention, initially, the second receiving roller is located above the second synchronous conveyor belt. The third moving unit transports the cut profile to several second receiving rollers. The second moving cylinder is activated to drive the second connecting block to move downward. As the second connecting block moves, the second moving plate moves downward. As the second moving plate moves, the second receiving roller moves downward until it is below the surface of the second synchronous conveyor belt. The second moving cylinder then stops operating. At this point, the profile is located on several second synchronous conveyor belts and is transported by the second synchronous conveyor belts to a unified collection position.

[0035] Compared with the prior art, the present invention also has the following technical effects: This invention sequentially transports the profile to be processed between the fixed and movable clamping columns of the mounting base via a first conveying and moving structure; clamps the profile using the fixed and movable clamping columns and a lower pressure roller; performs drilling and cutting operations on the profile using a drilling unit and a cutting unit; and moves and transports the drilled and cut profile to a collection position via a second conveying and moving structure. Compared with existing technologies, this invention reduces manual operations in the profile processing, thereby reducing labor costs and improving overall production efficiency. During the drilling and cutting operations, the profile is clamped by the first conveying and moving structure and limited by the support roller, fixed clamping column, movable clamping column, and lower pressure roller, which improves the stability of the profile and reduces the need for operators to hold the profile closely during drilling and cutting, thus improving safety in the production process.

[0065] The conveying direction of the second synchronous conveyor belt 40 is parallel to the axis of the second receiving roller 39. The side of the second moving plate away from the second connecting block is opposite to the second synchronous conveyor belt 40. Each second receiving roller 39 is located between adjacent second synchronous conveyor belts 40.

[0066] Detailed implementation of this embodiment: The profile to be processed is placed on several first synchronous conveyor belts 5. The first synchronous conveyor belts 5 start running. When the profile moves above the first receiving roller 2 and one side of the profile abuts against the positioning roller 4, the first synchronous conveyor belt 5 stops running. The first moving cylinder 6 is activated, driving the first connecting block 7 to move upward. As the first connecting block 7 moves, it can drive the first moving plate 1 to move upward. As the first moving plate 1 moves, it can drive the first receiving roller 2 to move upward. During the upward movement of the first receiving roller 2, the first receiving roller 2 will contact the profile on the first synchronous conveyor belt. The first receiving roller 2 continues to move upward to above the first synchronous conveyor belt 5. The first receiving roller 2 can push the profile to move above the first synchronous conveyor belt 5. At this time, the profile is located on the first receiving roller 2, and the first moving cylinder 6 stops running.

[0067] Start the horizontal linear motor 9, driving the vertical linear motor 10 to move closer to the profile until the top clamping roller 11 is above the profile, at which point the horizontal linear motor 9 stops running; start the vertical linear motor 10, driving the top clamping roller 11 to move downwards until the bottom of the top clamping roller 11 contacts the top of the profile, at which point the vertical linear motor 10 stops running, and the top clamping roller 11 limits the profile in the height direction; start the side linear motor 13, driving the two moving clamping columns 12 to move closer to each other until the two moving clamping columns 12 contact the two sides of the profile respectively, at which point the side linear motor 13 stops running, and the two moving clamping columns 12 limit the profile.

[0068] The second linear motor 14 is started, driving the clamping rod 32 to move closer to the end of the profile until the end of the profile is between the two clamping fingers 37, at which point the second linear motor 14 stops running. The clamping cylinder 34 is started, driving the ends of the two first connecting rods 35 that are hinged to the output shaft of the clamping cylinder 34 to move away from the clamping cylinder 34, causing the other ends of the two first connecting rods 35 to move away from each other, thereby pushing the ends of the two second connecting rods 36 that are hinged to the first connecting rods 35 to move away from each other. Since the other end of the second connecting rod 36 is rotatably connected to the mounting cylinder 33, the ends of the two second connecting rods 36 that are away from the first connecting rod 35 will move towards each other, thereby driving the two clamping fingers 37 to move closer to each other until the clamping fingers 37 abut against the two sides of the profile. At this time, the two clamping fingers 37 clamp the profile together, and the clamping cylinder 34 stops running.

[0069] Start the first punching linear motor 41 to drive the punching machine 47 to move closer to the first receiving roller 2; start the first linear motor 31 to drive the moving seat 15 to move closer to the punching machine 47; until the punching machine 47 and the moving seat 15 are arranged sequentially along the same side of the first receiving roller 2 and are adjacent to each other.

[0070] Start the second linear motor 14 to drive the clamping rod 32 and the profile to move closer to the moving seat 15 until the profile is on the support roller 16. Then, the second linear motor 14 stops running. At this time, the profile is between the fixed clamping column 18 and the moving clamping column. Start the first moving linear motor 17 to drive the moving clamping column to move closer to the profile. During the movement, the moving clamping column will contact one side of the profile and push the profile closer to the fixed clamping column 18 until the side of the profile away from the moving clamping column contacts the fixed clamping column 18. Then, the first moving linear motor 17 stops running. The fixed clamping column 18 and the moving clamping column jointly clamp the profile. Start the second moving linear motor 19 to drive the moving rod 20 to move closer to the profile until the lower pressure roller 22 is above the profile. Then, the second moving linear motor 19 stops running. Start the lower pressure cylinder 21 to drive the lower pressure roller 22 to move closer to the profile until the lower pressure roller 22 contacts the top of the profile. Then, the lower pressure cylinder 21 stops running.

[0071] Start the vertical linear motor 10 to drive the top clamping roller 11 to move upward until the bottom of the top clamping roller 11 separates from the profile, and the vertical linear motor 10 stops running; start the horizontal linear motor 9 to drive the vertical linear motor 10 and the top clamping roller 11 to move away from the profile until the top clamping roller 11 is away from the profile, and the horizontal linear motor 9 stops running; start the side linear motor 13 to drive the two moving clamping columns 12 to move away from the profile until both moving clamping columns 12 are separated from the profile, and the side linear motor 13 stops running.

[0072] The second linear motor 14 is started to drive the profile to continue moving. At the same time, the first linear motor 31 is started to drive the moving seat 15 to move synchronously with the profile. Meanwhile, the first drilling linear motor 41 is started to drive the drilling machine 47 to move until the hole to be processed on the profile corresponds to the drilling machine 47. The first linear motor 31, the second linear motor 14, and the first drilling linear motor 41 all stop running, and the drilling machine 47 performs the drilling operation.

[0073] After completing the drilling operation at the above positions, the second linear motor 14 is started to drive the profile to continue moving until the position to be drilled corresponds to the position of the drilling machine 47. The second linear motor 14 then stops running, and the drilling machine 47 begins the drilling operation. The cutting linear motor is started to drive the cutting bracket and the cutting machine to the position to be cut. The cutting linear motor then stops running. When the cutting machine moves to the position to be cut on the profile, the third linear motor 23 is started to drive the mounting bracket 24 to move above the profile and position the profile between the movable plate 30 and the fixed plate 25. The third linear motor 23 then stops running, and the cutting machine begins the cutting operation, thus completing the drilling and cutting of a section of the profile. After the cutting operation is completed, the conveying cylinder 28 is started to drive the push rod 29 and the movable plate 30 to move towards the profile until the movable plate 30 abuts against the profile. The conveying cylinder then stops running. Step 28 stops operating. At this time, the movable plate 30 and the fixed plate 25 together clamp the cut profile. After the movable plate 30 and the fixed plate 25 clamp the cut profile on both sides, the third linear motor 23 is started to drive the mounting frame 24 and the profile to move onto the second receiving roller 39. The third linear motor 23 stops operating, and the second moving cylinder is started to drive the second connecting block to move downward. As the second connecting block moves, it can drive the second moving plate to move downward. As the second moving plate moves, it can drive the second receiving roller 39 to move downward until the second receiving roller 39 moves below the conveyor belt surface of the second synchronous conveyor belt 40. The second moving cylinder stops operating. At this time, the profile is located on several second synchronous conveyor belts 40 and is transported by the second synchronous conveyor belts 40 to a unified collection position. The above operation is repeated to complete the subsequent drilling and cutting operations of the profile.
