Description

A fully automated laser engraving device for charger casings Technical Field

[0001] This invention relates to the field of laser engraving technology, and in particular to a fully automatic laser engraving device for charger housings. Background Technology

[0002] Laser engraving, also known as laser carving, is a process that uses a laser beam to carve patterns and text onto various materials. This technology typically uses ultraviolet lasers, which have a short wavelength and can generate a high-energy laser beam. This generates enough heat on the material surface to cause the atoms on the surface to evaporate or melt instantly, thus forming the desired pattern or text.

[0003] After production, charger casings require marking to indicate various parameters and the manufacturer's logo. Currently, most marking of charger casings is done using laser engraving. Existing laser engraving equipment is divided into fixed laser marking machines and visual laser marking machines. Fixed laser marking machines require manual fixing of the charger casing before operation, and after marking, the casing must be manually removed and a new one fixed, resulting in high reliance on manual labor and low efficiency. Visual laser marking machines, on the other hand, transport the charger casing via a conveyor belt. After the casing passes through the marking module, it is automatically captured and marked. While this improves marking efficiency, the side of the casing that is in contact with the conveyor belt cannot be marked, requiring manual flipping and repositioning for secondary marking, making the overall efficiency still relatively low. Summary of the Invention

[0004] To address the technical problems existing in the prior art, a fully automatic laser engraving device for charger housings that can automatically flip over is provided.

[0005] The technical implementation of this invention is as follows: a fully automatic laser engraving device for charger housings, comprising a base, a feeding mechanism, and a longitudinal laser module; a worktable is provided at the front of the top of the base to provide a platform for laser engraving of the charger housing; a square hole is cut out on the worktable; a mounting bracket is provided on the base to adjust the height of the longitudinal laser module; the longitudinal laser module is used to mark the charger housing; the feeding mechanism can transport the charger housing to the longitudinal laser module for marking and can also flip the charger housing, including: an intermittent conveying component for transporting the charger housing to the worktable; a clamping component for gripping the charger housing transported by the intermittent conveying component; a rotating component for switching the charger housing by rotation; and a flipping component for flipping the charger housing so that the side away from the laser beam emission port of the longitudinal laser module can also be marked.

[0006] Furthermore, the intermittent conveying assembly includes: a suction cup base disposed on the left side of the base and with its top flush with the height of the worktable surface; a conveyor belt mounted on the top of the suction cup base for placing and conveying the charger housing; a four-slotted wheel disposed on the left-hand rotating shaft of the conveyor belt; a servo motor capable of providing power for the operation of the conveyor belt; and a cylindrical pin mounted on the output shaft of the servo motor, capable of rotating synchronously with the output shaft of the servo motor, and capable of engaging in a special groove of the four-slotted wheel and driving it to rotate.

[0007] Furthermore, the rotating assembly includes: a transverse perforated plate installed on the bottom of the worktable surface and spanning the square hole; an electric push rod I installed on the bottom of the transverse perforated plate and having its movable rod protruding through the hole in the transverse perforated plate; a slotted cylinder rotatably installed on the top of the movable rod of the electric push rod I; a fixing block fixedly disposed on the top of the transverse perforated plate; a drive rod that slides out of the fixing block and has its end engaged in the slotted hole on the slotted cylinder, and is capable of driving the slotted cylinder to rotate; and a buffer spring disposed between the drive rod and the fixing block, capable of buffering and protecting the drive rod and the slotted cylinder.

[0008] Furthermore, the clamping assembly includes: a bearing seat embedded in the groove and capable of rotating synchronously with the groove; a four-way guide sleeve disposed on the top of the bearing seat; four mating blocks rotatably disposed in the four guide openings of the four-way guide sleeve; a torsion spring disposed between the mating blocks and the four-way guide sleeve to assist the mating blocks in resetting; a U-shaped frame fixedly connected to the mating blocks; a clamping member disposed within the U-shaped frame for clamping the charger housing; and a pressure spring disposed between the clamping member and the U-shaped frame to increase the clamping force of the clamping member.

[0009] Furthermore, the flipping assembly includes: a full gear disposed near the end of the U-shaped frame and the docking block, capable of rotating synchronously with the U-shaped frame; a longitudinal perforated plate mounted on the bottom of the worktable; an electric push rod II mounted on the bottom of the longitudinal perforated plate, with its movable rod passing through the hole in the longitudinal perforated plate and simultaneously passing through the square hole; and a rack disposed at the top of the movable rod of the electric push rod II, meshing with the full gear, and capable of driving the full gear to rotate during lifting and lowering.

[0010] Furthermore, the U-shaped frame is provided with a spreading component that allows the clamping member to open and remove the charger housing it is holding. The spreading component includes: a folding rod mounted on the worktable; a wedge block disposed on one end of the folding rod near the clamping member; an N-shaped frame disposed on the top of the U-shaped frame; an expansion member slidably disposed on the N-shaped frame and capable of spreading the clamping member open with the cooperation of the wedge block; and a return spring disposed between the N-shaped frame and the expansion member for resetting the expansion member.

[0011] Furthermore, the expansion member is divided into upper and lower parts. The upper part is set as an inclined surface that matches the wedge block, and when it comes into contact with the wedge block, it will be pressed down and moved downward. The lower part is set as a triangular plate with the tip pointing downward, which can open the clamping member when it moves downward, so that the charger shell can fall down.

[0012] Furthermore, the workbench is also provided with a guide plate that can guide the charger housing falling from the clamping member. The guide plate is installed in a position corresponding to the folding rod and is inclined to the lower right. A material frame for storing the charger housing is provided at the right end of the base. The height of the material frame is lower than the lowest point of the guide plate, which can collect the charger housing that slides off the guide plate.

[0013] Furthermore, a horizontal laser module is also provided at the rear top of the base. The horizontal laser module can mark the side of the charger shell with conductive pillars, which can further improve the marking efficiency of the charger shell.

[0014] Furthermore, the top of the base is also provided with a dust collection component capable of handling the debris generated during marking. The dust collection component includes: a dust collection trough frame disposed on the top of the base, directly below the marking position, for collecting the debris; and a vacuum cleaner installed on the base, connected to the dust collection trough frame through a pipe, and for sucking up the debris therein.

[0015] The present invention has the following advantages: 1. The present invention uses a feeding mechanism to transport the charger shell by a conveyor belt and clamps it with a clamping component at the corresponding position. The electric push rod I is activated to raise the slot cylinder, and the drive rod slides in the groove inside the slot cylinder, forcing the slot cylinder to rotate the bearing seat. The clamping component holding the charger shell is rotated to the longitudinal laser module for marking. After marking is completed, the rack can be raised by activating the electric push rod II, which drives the full gear at the corresponding position to rotate. The full gear then drives the docking block and U-shaped frame to rotate, flipping the charger shell over, thus achieving marking on its bottom surface.

[0016] 2. By setting up the expansion component, when the grooved cylinder drives the bearing seat to rotate, the inclined part at the top of the expansion component will contact the wedge block. Under the pressure of the wedge block, the expansion component will slide downward, thereby opening the clamping component. There is no need to manually remove the charger shell from the clamping component, reducing the device's dependence on manpower.

[0017] 3. By setting up a guide plate and a material box, the charger casing can be guided by the guide plate and collected by the material box when it falls from the clamp, which further improves the intelligence of the device;

[0018] 4. By setting up a dust collection component, the dust collection trough frame collects the debris generated during marking and then sucks it up with a vacuum cleaner, ensuring the cleanliness of the production workshop. Attached Figure Description

Detailed Implementation

[0029] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0030] Before describing the embodiments in detail, it should be understood that the embodiments are not limited to specific embodiments and can be implemented or carried out in various ways.

[0031] First embodiment: A fully automatic laser engraving device for charger housings, as shown in Figures 1-7, includes a base 1, a feeding mechanism, and a longitudinal laser module 6; a worktable 101 providing a platform for laser engraving of the charger housing is provided at the front of the top of the base 1; a square hole 102 is cut out in the worktable 101; a mounting bracket 5 is provided on the base 1 to adjust the height of the longitudinal laser module 6; the longitudinal laser module 6 is used to mark the charger housing; the feeding mechanism can transport the charger housing to the longitudinal laser module 6 for marking and can also flip the charger housing, including:

[0032] Intermittent conveying assembly 2, which can convey the charger shell to be marked onto the workbench 101, includes: a suction cup base 21, which is located on the left side of the base 1, closely attached to the left side of the base 1, and its height is flush with the workbench 101 on top of the base 1; a conveyor belt 22, which is installed on top of the suction cup base 21, allowing the worker to input the charger shell from its left side and convey it to the right; and a four-slotted wheel 23, which has symmetrical special slots and is located at the front end of the shaft on the left side of the conveyor belt 22. The four-slotted wheel 23 rotates 90° each time, driving the conveyor belt 22 to operate. Servo motor 24 is mounted on suction cup base 21 and provides power for the rotation of quarter-grooved wheel 23. Cylindrical pin 25 is fixed on the output shaft of servo motor 24 and its shape matches the special slot on quarter-grooved wheel 23. Starting servo motor 24 can drive cylindrical pin 25 to rotate. Cylindrical pin 25 is inserted into the special slot on quarter-grooved wheel 23 and drives quarter-grooved wheel 23 to rotate through differential principle. For every rotation of cylindrical pin 25, quarter-grooved wheel 23 rotates a quarter rotation, thereby making conveyor belt 22 operate intermittently to control the conveying speed of charger housing.

[0033] The rotating assembly 3, capable of rotating to switch the charger housing to be marked, includes: a horizontal perforated plate 31, which is bolted to the bottom of the workbench 101, spanning the square hole 102, with its openings aligned with the square hole 102; an electric push rod I 32, mounted at the bottom of the horizontal perforated plate 31, with its movable rod passing through both the holes in the horizontal perforated plate 31 and the square hole 102; a slotted cylinder 33, rotatably connected to the movable rod of the electric push rod I 32, with four equally spaced, interconnected human-shaped slots on its outer wall, the human-shaped slots being divided into inclined and vertical sections; a fixing block 34, welded to the top right position of the horizontal perforated plate 31; and a drive rod 35, which slides through the fixing block 34. The left end is spherical and fits into the slot on the grooved cylinder 33. When the movable rod of the electric push rod I 32 extends, it pushes the grooved cylinder 33 to rise. At the same time as the grooved cylinder 33 rises, the drive rod 35 slides along the inclined groove of the human-shaped groove on the grooved cylinder 33 and presses the grooved cylinder 33 to rotate 90° clockwise. When the movable rod of the electric push rod I 32 shortens and returns to its original position, the grooved cylinder 33 descends, and the drive rod 35 slides along the vertical groove of the human-shaped groove on the grooved cylinder 33 without driving it. The buffer spring 36 is set between the drive rod 35 and the grooved cylinder 33. It has a high stiffness coefficient and can provide sufficient support for the drive rod 35 when the grooved cylinder 33 rises and contacts the drive rod 35. At the same time, it provides space for the drive rod 35 to retreat when the pressure between the grooved cylinder 33 and the drive rod 35 is too large, thus providing buffer protection.

[0034] The clamping assembly 4, capable of gripping the charger housing transported to the right end of the conveyor belt 22, includes: a bearing seat 41, which is fixedly connected to the groove cylinder 33 in an embedded manner and can rotate synchronously with the groove cylinder 33; a four-way guide sleeve 42, which is fixedly connected to the top center of the bearing seat 41, and the four guide holes on the four-way guide sleeve 42 are perpendicular to each other; four docking blocks 43, which are rotatably disposed in the four guide holes of the four-way guide sleeve 42; and a torsion spring 44, which is disposed between the docking blocks 43 and the four-way guide sleeve 42. Between 2, after the docking block 43 rotates, it can assist in its reset; U-shaped frame 45, U-shaped frame 45 is fixedly set at the outer end of docking block 43; clamping member 46, clamping member 46 is installed inside U-shaped frame 45, its clamping part is slightly expanded outward, which can guide the charger shell on conveyor belt 22 to slide into its clamping part to complete the clamping; pressure spring 47, pressure spring 47 is set between clamping member 46 and U-shaped frame 45, which can apply pressure to clamping member 46 after clamping charger shell, so that its clamping force is greater and the clamping of charger shell is more stable.

[0035] The flipping assembly 8, after marking the upper surface of the charger housing, can flip it over so that the lower surface can also be marked. It includes: a full gear 81, positioned between the U-shaped frame 45 and the mating block 43, capable of rotating synchronously with both; a longitudinal perforated plate 82, bolted to the bottom of the worktable 101, with its holes aligned with the square hole 102; and an electric push rod II 83, mounted at the bottom of the longitudinal perforated plate 82, its movable rod passing through both the holes in the longitudinal perforated plate 82 and the square hole 102; and a gear... The rack 84 is located at the top of the movable rod of the electric push rod II 83. When the movable rod of the electric push rod II 83 extends, the rack 84 moves upward and contacts the gear 81, driving it to rotate. This causes the U-shaped frame 45 and the docking block 43 to rotate synchronously. The torsion spring 44 stores force accordingly, and the clamping member 46 also rotates at the same time, so that the bottom of the charger housing with the marking side faces upward. After marking is completed, the movable rod of the electric push rod II 83 retracts and resets, and under the meshing action, the U-shaped frame 45 and the docking block 43 rotate back to their original positions. The torsion spring 44 can also play an auxiliary role in this process.

[0036] When using this device to mark the charger casing, the worker simply places the charger casing on the left end of the conveyor belt 22. The servo motor 24 drives the cylindrical pin 25 to rotate. The cooperation between the cylindrical pin 25 and the quarter-grooved wheel 23 causes the conveyor belt 22 to operate intermittently, ensuring the conveying speed of the charger casing matches the subsequent turning speed. When the charger casing reaches the right end of the conveyor belt 22, it is gripped by the clamping member 46. Then, the electric push rod I 32 is activated to raise the grooved cylinder 33, and under the action of the drive rod 35, the grooved cylinder 33 rotates clockwise. Rotating 90° causes the bearing seat 41 to rotate 90° as well, causing the clamping member 46 holding the charger housing to rotate directly below the vertical laser module 6. The vertical laser module 6 is pre-set and can directly mark the upper surface of the charger housing. After marking the upper surface, the electric push rod II 83 is activated to push the rack 84 upward, driving the corresponding full gear 81 to rotate. The docking block 43 and the U-shaped frame 45 then rotate 180°, so that the lower surface of the charger housing faces upward, and the vertical laser module 6 marks it again.

[0037] Second embodiment: Based on the first embodiment, as shown in Figures 1 and 8, a spreading component 9 is provided on the U-shaped frame 45 to allow the clamping member 46 to open and remove the charger shell it is clamping. The spreading component 9 includes: a folding rod 91, which is fixedly installed on the right side of the workbench 101; a wedge block 92, which is located at the left end of the folding rod 91 and has a bottom surface that slopes forward and downward; an N-shaped frame 93, which is welded to the top of the U-shaped frame 45; and an expansion member 94, which is slidably disposed in the middle of the N-shaped frame 93 and is divided into upper and lower parts. The upper part is designed as an upward and backward inclined surface. When it rotates to contact the wedge block 92, it will be pressed downward along the inclined surface of the wedge block 92. The lower part is designed as a triangular plate with the tip pointing downward, and the tip is inserted into the clamping member 46. When it is pressed downward by the wedge block 92, it can open the clamping member 46, so that the clamping member 46 is separated from the charger shell and falls down. The return spring 95 is set between the N-shaped frame 93 and the expansion member 94. After the expansion member 94 is separated from the wedge block 92, it will rise to its original position under the action of the return spring 95.

[0038] As shown in Figure 1, a guide plate 10 is also provided on the workbench 101. The guide plate 10 is installed on the right side of the workbench 101, directly below the wedge block 92, and angled downwards to the right. After the charger shell is disengaged from the clamping member 46, it will fall onto the guide plate 10 and slide to the right along the angle. A material frame 11 is provided at the right end of the base 1. The height of the material frame 11 is lower than that of the guide plate 10 and is located directly below the right end of the guide plate 10. The charger shell will slide into the material frame 11 through the guide plate 10 for unified collection. A horizontal laser module 7 is also provided at the rear top of the base 1. The horizontal laser module 7 can mark the rear side of the charger shell, thereby further improving the marking efficiency of the charger shell.

[0039] As shown in Figures 1 and 9, a dust collection component 12 is also provided on the top of the base 1 to handle the debris generated during marking. The dust collection component 12 includes: a dust collection frame 122, which is located in the middle of the top of the base 1, directly below the marking position, and can collect the debris generated during the marking process; and a vacuum cleaner 121, which is installed on the base 1 and connected to the dust collection frame 122 through a pipe. When the vacuum cleaner 121 is activated, it can suck up the debris in the dust collection frame 122, and the suction action makes it easier for the debris to enter the dust collection frame 122.
