Description

Technical Field

[0001] This invention relates to the field of laser processing technology, and in particular to a laser processing equipment for automotive parts. Background Technology

[0002] A large number of parts are used in automobile production and processing, such as box-shaped workpieces. When processing box-shaped workpieces, laser processing is required, such as laser drilling and laser cutting.

[0003] In existing technologies, when processing box-shaped workpieces, the workpiece is placed with its opening facing upwards and its outer side is fixed. This causes the structure fixing the outer side of the workpiece to affect the movement of the laser head when it is continuously processing the four sides and bottom of the workpiece. As a result, after the laser head has completed processing one or more sides of the workpiece, it is necessary to readjust the position of the workpiece before processing the remaining sides, leading to low efficiency. Furthermore, with the workpiece opening facing upwards, waste generated during laser processing can fall into the workpiece, potentially damaging it. Additionally, the waste needs to be removed from the workpiece. Summary of the Invention

[0004] To overcome the shortcomings mentioned above, this invention provides a laser processing equipment for automotive parts, comprising a laser cutting component, a fixing component, an XY-axis moving component, an extraction and collection component, and a linear actuator. The fixing component is disposed within the laser processing area of ​​the laser cutting component. A box-shaped workpiece is placed on the fixing component with its opening facing downwards, and the fixing component secures the box-shaped workpiece from the inside. An XY-axis moving component is mounted on the fixing component. A linear actuator is fixedly connected to the moving part of the XY-axis moving component. An extraction and collection component for extracting smoke and collecting waste from the inside of the box-shaped workpiece is mounted on the telescopic part of the linear actuator. The linear actuator drives the extraction and collection component to move up and down, and the XY-axis moving component drives the extraction and collection component to move forward, backward, left, and right.

[0005] Preferably, the fixing assembly includes a mounting plate and fixing rods; multiple fixing rods are fixedly connected to the mounting plate; expansion fixing components are provided on the fixing rods, and the box-shaped workpiece is placed on the fixing rods with its opening facing down, and the expansion fixing components expand to fix the inner side of the box-shaped workpiece.

[0006] Preferably, the XY axis moving assembly includes a first guide rail assembly and a second guide rail assembly; the first guide rail assembly is mounted on a mounting plate, and the second guide rail assembly is fixedly connected to the moving part of the first guide rail assembly; the linear actuator is mounted on the moving part of the second guide rail assembly.

[0007] Preferably, the suction collection assembly includes a suction housing, a suction pipe, a door opening / closing assembly, and a filter assembly. The suction housing is fixed to the telescopic part of the linear actuator. The bottom of the suction housing is connected to the suction pipe, which provides suction force to the suction collection assembly and draws out the smoke. Multiple suction holes are provided on the side of the suction housing. When laser processing a box-shaped workpiece, the suction housing is moved so that the suction holes are aligned with the laser head of the laser cutting assembly. A door opening / closing assembly is installed at each suction hole, and the suction holes of the suction housing are opened and closed by controlling the opening and closing of the door opening / closing assembly. A filter assembly is detachably connected to the bottom of the suction housing to collect waste generated during laser processing.

[0008] Preferably, the upper side of the suction housing is provided with an opening. When laser processing the bottom surface of the box-shaped workpiece, the suction housing uses the upper opening to draw in the generated fumes and collect the generated waste.

[0009] Preferably, the door opening and closing assembly includes a frame, a rotating door, and a driver; the frame is fixedly connected to a suction hole in the suction housing, and the rotating door is rotatably connected in the frame; the driver is connected to the rotating shaft of the rotating door, and the driver drives the rotating door to rotate actively, and the driver is mounted on the suction housing.

[0010] Preferably, the device also includes a protrusion, with the protrusion fixed to the side of the rotating door away from the center of the suction housing; the mounting position of the rotating door's pivot on the frame is close to the center of the suction housing; and the protrusion does not protrude outward from the frame when the rotating door is closed.

[0011] Preferably, the filter assembly is a filter screen with a hopper on the upper side and a collection section on the lower side; the flue gas can pass through the filter assembly and be sucked away by the suction pipe, while the waste is intercepted by the filter assembly, guided by the hopper and collected in the collection section.

[0012] Preferably, a vertical pressure bar is fixed to the bottom of the collecting section, with the upper side of the vertical pressure bar extending beyond the hopper; the upper side of the vertical pressure bar is connected to the upper side of the hopper via an elastic rope.

[0013] Preferably, a downward pressing ball is provided on the upper side of the vertical pressure rod. When the rotating door rotates and passes the downward pressing ball, the rotating door presses the downward pressing ball down, and the downward pressing ball squeezes the filter screen downward through the vertical pressure rod.

[0014] Compared with existing technologies, this invention has the following advantages: This invention achieves stable clamping from the inside of the inverted box-shaped workpiece using a fixing rod, ensuring no obstructions on the outside of the workpiece and eliminating interference from laser head movement. It allows for continuous laser processing of all four sides and the bottom surface in one operation without repeated adjustments to the workpiece's posture and clamping. The three-dimensional movement of the suction and collection assembly ensures the suction port always faces the laser processing position from the inside of the workpiece, opening only the suction hole facing the processing position, significantly improving the efficiency of flue gas extraction and waste collection. This invention innovatively adds a protrusion ejection structure. The protrusion of the protrusion during the rotation of the rotating door pushes large pieces of waste outwards; the rotating door presses against the vertical pressure rod, causing the filter screen to elastically deform, guiding waste to the collection section efficiently while preventing filter screen blockage due to waste accumulation.

Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] Example 1: As Figures 1-9 As shown, a laser processing equipment for automotive parts includes a laser cutting component 1, a fixing component 2, an XY axis moving component 3, an absorption collection component 4, and a linear actuator 5; the fixing component 2 is disposed within the laser processing area of ​​the laser cutting component 1.

[0027] The box-shaped workpiece 100 is placed on the fixing component 2 with its opening facing downwards. The fixing component 2 fixes the box-shaped workpiece 100 from the inside. An XY axis moving component 3 is installed on the fixing component 2. A linear actuator 5 is fixedly connected to the moving part of the XY axis moving component 3. A suction and collection component 4 for drawing smoke and collecting waste from the inside of the box-shaped workpiece 100 is installed on the telescopic part of the linear actuator 5. The linear actuator 5 drives the suction and collection component 4 to move up and down, and the XY axis moving component 3 drives the suction and collection component 4 to move forward, backward, left and right.

[0028] The fixing assembly 2 includes a mounting plate 21 and fixing rods 22; multiple fixing rods 22 are fixedly connected to the mounting plate 21; expansion fixing members 22a are provided on the fixing rods 22. The box-shaped workpiece 100 is placed on the fixing rods 22 with its opening facing down, and the box-shaped workpiece 100 is fixed to the inside by the expansion fixing members 22a. In this way, the fixing assembly 2 can be fixed from the inside of the box-shaped workpiece 100. There is no obstruction structure on the outside of the box-shaped workpiece 100, which facilitates the movement of the laser head in the laser cutting assembly 1. The laser head can perform continuous laser processing on the four sides and bottom of the box-shaped workpiece 100 without readjusting the box-shaped workpiece 100.

[0029] The XY axis moving assembly 3 includes a first guide rail assembly 31 and a second guide rail assembly 32; the first guide rail assembly 31 is mounted on the mounting plate 21, and the second guide rail assembly 32 is fixedly connected to the moving part of the first guide rail assembly 31; the linear actuator 5 is mounted on the moving part of the second guide rail assembly 32; the first guide rail assembly 31 and the second guide rail assembly 32 are arranged perpendicular to each other, and the first guide rail assembly 31 drives the suction and collection assembly 4 to move back and forth, and the second guide rail assembly 32 drives the suction and collection assembly 4 to move left and right.

[0030] The suction collection assembly 4 includes a suction housing 41, a suction pipe 42, a door opening and closing assembly 43, and a filter assembly 44. The suction housing 41 is fixed to the telescopic part of the linear actuator 5. The bottom of the suction housing 41 is connected to the suction pipe 42, which provides suction force to the suction collection assembly 4 and draws out the smoke. The suction housing 41 has multiple suction holes on its side (specifically 4 in this embodiment). When laser processing the box-shaped workpiece 100, the suction housing 41 is moved so that the suction holes face the laser head of the laser cutting assembly 1. In this way, the suction holes can draw away the generated smoke and the generated waste is also sucked into the suction housing 41. A door opening and closing assembly 43 is installed at each suction hole. By controlling the opening and closing of the door opening and closing assembly 43, each suction hole of the suction housing 41 can be opened and closed. In this way, only the suction hole facing the laser head can be opened. The filter assembly 44 is detachably connected to the bottom of the suction housing 41 to collect the waste generated by laser processing.

[0031] The suction housing 41 has an opening on its upper side, meaning the upper side of the suction housing 41 is not sealed. During laser processing of the bottom surface (upper side shown in the attached figure) of the box-shaped workpiece 100, the suction housing 41 uses the upper opening to draw in the generated fumes and collect the generated waste. Of course, a door assembly 43 can also be provided at the upper opening of the suction housing 41 to realize the active opening and closing of the opening.

[0032] The door opening and closing assembly 43 includes a frame 431, a rotating door 432, and a driver 433. The frame 431 is fixed to a suction hole in the suction housing 41, and the rotating door 432 is rotatably connected in the frame 431. The driver 433 is connected to the rotating shaft of the rotating door 432, and the driver 433 drives the rotating door 432 to rotate actively. The driver 433 is mounted on the suction housing 41.

[0033] A large number of parts are used in automobile production and processing, such as box-shaped workpieces. When processing box-shaped workpieces, laser processing is required, such as laser drilling and laser cutting.

[0034] In existing technologies, when processing box-shaped workpieces, the workpiece is placed with its opening facing upwards and its outer side is fixed. This causes the structure fixing the outer side of the workpiece to affect the movement of the laser head when it is continuously processing the four sides and bottom of the workpiece. As a result, after the laser head has completed processing one or more sides of the workpiece, it is necessary to readjust the position of the workpiece before processing the remaining sides, leading to low efficiency. Furthermore, with the workpiece opening facing upwards, waste generated during laser processing can fall into the workpiece, potentially damaging it. Additionally, the waste needs to be removed from the workpiece.

[0035] When using this invention, such as Figures 1-2 As shown, the box-shaped workpiece 100 is placed on the fixing component 2 with its opening facing down, that is, the box-shaped workpiece 100 is upside down on the fixing component 2. The fixing component 2 fixes the box-shaped workpiece 100 from the inside. In this way, the laser head of the laser cutting component 1 will not be blocked by the fixing component 2 when it moves, and the laser head can perform laser processing on the four sides and bottom of the box-shaped workpiece 100 without obstruction.

[0036] When the laser head performs laser processing on the box-shaped workpiece 100, the XY axis moving component 3 controls the suction and collection component 4 to move forward, backward, left, and right, and the linear actuator 5 controls the suction and collection component 4 to move up and down. This allows the side suction holes or top openings of the suction housing 41 to face the laser head directly from the inside of the box-shaped workpiece 100. Furthermore, it is possible to control only the door opening component 43 facing the laser head to open, while the other door opening components 43 are closed, in order to improve the suction force. Of course, if the door opening component 43 is not installed on the top opening of the suction housing 41, it will not affect the suction force of the side suction holes of the suction housing 41. When the laser head performs laser processing, it will also blow air outward, blowing the fumes into the suction housing 41. When the suction and collection component 4 is working, the generated fumes are sucked away through the suction pipe 42, and the waste is sucked into the inside of the suction housing 41. The waste is intercepted and collected by the filter component 44.

[0037] Furthermore, after the laser head completes the processing of one side of the box-shaped workpiece 100, the suction collection assembly 4 moves with the laser head from one side of the processed surface of the box-shaped workpiece 100 to the other side. At the same time, another suction hole of the suction housing 41 also moves close to the other processed surface of the box-shaped workpiece 100. Then, by changing the orientation and movement position of the laser head and only opening the switch door assembly 43 facing the processed surface, the present invention can realize the continuous laser processing of the box-shaped workpiece 100 by the laser head. In addition, when the bottom surface (the upper side shown in the figure) of the box-shaped workpiece 100 is laser processed, all the switch door assemblies 43 can be closed.

[0038] Furthermore, such as Figures 8-9 As shown, it also includes a protrusion 434. The protrusion 434 is fixedly connected to the side of the rotating door 432 away from the center of the suction housing 41. The mounting position of the rotating shaft of the rotating door 432 on the frame 431 is close to the center of the suction housing 41. When the rotating door 432 is closed, the protrusion 434 does not protrude outward from the frame 431.

[0039] When the laser head of this invention is used for laser cutting, and it is necessary to cut large pieces of waste material, such as... Figure 8 As shown, at this time, large pieces of waste need to be discharged to the outside to prevent them from falling into the inner side of the box-shaped workpiece 100. During cutting, the opening and closing door assembly 43 facing this direction is controlled to open only part of the rotating door 432. This ensures the smoke extraction effect while preventing large pieces of waste from being driven by the suction force. After the laser cutting is completed, the rotating door 432 is controlled to rotate outward, and the protruding protrusion 434 is used to contact the large pieces of waste, pushing them outward and onto the ground.

[0040] Furthermore, such as Figures 5-7 As shown, the filter assembly 44 is a filter screen with a hopper 44a on the upper side and a collection section 44b on the lower side. The flue gas can pass through the filter assembly 44 and be sucked away by the suction pipe 42, while the waste is intercepted by the filter assembly 44, guided by the hopper 44a and collected in the collection section 44b.

[0041] A vertical pressure rod 441 is fixed to the bottom of the collection section 44b, and the upper side of the vertical pressure rod 441 extends beyond the hopper section 44a; the upper side of the vertical pressure rod 441 is connected to the upper side of the hopper section 44a by an elastic rope 442. A downward pressure ball is provided on the upper side of the vertical pressure rod 441. When the rotating door 432 rotates past the downward pressure ball, the rotating door 432 presses the downward pressure ball down, and the downward pressure ball squeezes the filter screen downward through the vertical pressure rod 441, wherein the elastic filter screen can be a metal mesh.

[0042] When waste is drawn onto the filter assembly 44, it is guided by the hopper 44a to the collection section 44b, where it is collected. To prevent waste from accumulating on the hopper 44a and causing insufficient compaction in the collection section 44b, the present invention includes a vertical pressure rod 441 and an elastic rope 442. Each time the rotating door 432 rotates, the bottom of the rotating door 432 contacts and presses against the downward pressure ball. The downward pressure ball, using the vertical pressure rod 441, pushes the filter screen downward, causing elastic deformation. This allows the waste to be fully transferred and filled into the collection section 44b, enabling the collection section 44b to collect more waste while preventing waste from accumulating on the hopper 44a, which would affect the gas flow and suction effect.

[0043] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
