Description

Technical Field

[0001] This invention relates to the technical field of pen holder processing, and specifically to a marking device for a pen holder. Background Technology

[0002] Laser marking is an indispensable process in pen holder manufacturing, primarily used to mark key information such as product model, logo, and production date on the pen holder surface. The marking accuracy and efficiency directly impact product quality and production efficiency. Currently, most commercially available laser marking devices for pen holders only possess basic clamping and marking functions, exhibiting significant shortcomings in the impurity cleaning process before marking, becoming a key bottleneck restricting marking quality and production efficiency.

[0003] The main problems with existing pen holder marking devices are concentrated in the following aspects: First, during the production, storage and transportation of pen holders, dust, metal burrs, debris and other impurities easily adhere to their outer walls. Existing devices are not easy to adjust according to the size of the pen holder, making it difficult to remove impurities from the surface of the pen holder. These residual impurities will block the laser beam, resulting in blurry markings and unclear edges, affecting marking accuracy and product appearance consistency. Second, during long-term use, impurities easily accumulate on the cleaning mechanism and clamping components of existing devices, thus affecting the subsequent cleaning effect. Summary of the Invention

[0004] The purpose of this invention is to provide a marking device for a pen holder to overcome the above-mentioned defects in the prior art.

[0005] A marking device for a pen holder includes a laser marking machine connected to the side of a frame on a workbench via a lifting assembly. The workbench is provided with a pad, and a fixed frame connected to the workbench is provided across the pad. The pad is provided with a movable clamping mechanism for fixing the pen holder and driving its movement. The mounting bracket is equipped with a cleaning mechanism for cleaning impurities on the outside of the pen holder.

[0006] Preferably, the movable clamping mechanism includes a first drive screw, a right-angle motor, a movable frame, a drive motor, and a three-jaw chuck. The two ends of the first drive screw are rotatably connected to the two ends of the mounting groove on the pad. The right-angle motor is mounted on the outside of the pad and its output shaft is connected to one end of the first drive screw. The movable frame is slidably connected to the slide rail on the pad via a slider. The movable frame is screw-connected to the first drive screw via a screw nut. The drive motor is mounted on the side of the movable frame and its output shaft is provided with a three-jaw chuck. Each jaw of the three-jaw chuck is provided with an extension plate, and each extension plate has a stop block on its side.

[0007] Preferably, the cleaning mechanism includes a fixed cylinder, a driving plate, a cleaning brush and a tension spring. The fixed cylinder is coaxially arranged with the three-jaw chuck. Both sides of the fixed cylinder are respectively connected to both sides of the fixed frame through connecting plates. Two driving plates are provided and symmetrically arranged in the fixed frame and are hinged to the support plates on the inner wall of the fixed frame through pin shafts. The cleaning brush is connected to one end of the driving plate. A driving inclined surface is provided at the bent end of the driving plate. One end of the tension spring is connected to the inner wall of the fixed cylinder, and the other end of the tension spring is connected to the driving plate.

[0008] Preferably, the lifting component includes a driving screw rod II, a lifting seat and a fastening screw. Both ends of the driving screw rod II are respectively rotatably connected to the upper and lower ends of the machine frame. The lifting seat is helically connected to the driving screw rod II through a screw nut and its both sides are respectively slidably connected to the sliding grooves on the machine frame. The laser marking machine is arranged on the lifting seat. The fastening screw is threadedly connected to the machine frame and is used to abut the driving screw rod II against the machine frame.

[0009] Preferably, the overall shape of the cleaning brush is an arc structure. [[ID=۸]]

[0010] [[ID=۹]]Preferably, a discharge hole is provided at the lower end of the fixed cylinder.

[0011] Preferably, the fixed frame is of a "U" - shaped structure.

[0012] Preferably, two sliding rails are provided and symmetrically arranged on both sides of the backing plate.

[0013] Preferably, a hand wheel is provided at the upper end of the driving screw rod II.

[0014] The beneficial effects achieved by the present invention are as follows: 1. In this application, through the provision of a dedicated cleaning mechanism, the automatic and thorough cleaning of the impurities on the outer side of the pen barrel is realized, greatly improving the clarity and quality of laser marking. A cleaning mechanism composed of a fixed cylinder, a driving plate, a cleaning brush and a tension spring is arranged on the fixed frame. The cleaning brush adopts an arc structure adapted to the pen barrel and can closely fit the outer wall of the pen barrel. When the clamping mechanism moves the pen barrel towards the cleaning mechanism, the end of the pen barrel presses the driving inclined surface of the driving plate, forcing the driving plate to带动 the cleaning brush to approach and fit the pen barrel.配合 the driving motor to带动 the pen barrel to rotate uniformly, the cleaning brush generates friction with the surface of the pen barrel, which can efficiently remove the impurities on the outer wall of the pen barrel and avoid problems such as blurred marking and poor adhesion caused by impurities blocking the laser beam. At the same time, a discharge hole is provided at the lower end of the fixed cylinder, and the impurities generated during the cleaning process can directly fall into the fixed cylinder and be discharged through the discharge hole, avoiding the accumulation of impurities on the cleaning mechanism or the surface of the pen barrel and further ensuring the cleaning effect.

[0015] 2. The cleaning mechanism of this application is linked with the moving clamping mechanism to achieve synchronous cleaning of impurities in the gap between the extended plates. The three-jaw chuck is equipped with an extended plate and a stop on the jaws. When the pen holder moves to the end of the cleaning mechanism, the stop contacts the driving inclined surface of the drive plate, which drives the cleaning brush to move closer to the extended plate. This can simultaneously clean the impurities accumulated in the gap between the extended plates. In addition, after cleaning is completed, when the moving frame is reset, the drive plate is reset under the action of the tension spring, and the cleaning brush shakes and detaches the impurities attached to it, preparing for the next cleaning.

[0025] As Figures 1-5 shown, the present invention provides a marking device for a pen holder, including a laser marking machine 3 connected to the side of a frame 2 on a workbench 1 through a lifting component 6. A backing plate 4 is provided on the workbench 1, and a "U"-shaped fixing frame 5 connected to the workbench 1 spans across the backing plate 4; In addition, the lifting component 6 includes a driving screw rod two 61, a lifting seat 63, and a tightening screw 64. The two ends of the driving screw rod two 61 are respectively rotatably connected to the upper and lower ends of the frame 2. A handwheel 62 is provided at the upper end of the driving screw rod two 61 to facilitate an operator to manually adjust the height of the laser marking machine 3. The lifting seat 63 is helically connected to the driving screw rod two 61 through a screw nut and its two sides are respectively slidably connected to sliding grooves 21 on the frame 2. The laser marking machine 3 is provided on the lifting seat 63. The tightening screw 64 is threadedly connected to the frame 2 and is used to abut the driving screw rod two 61 against the frame 2 to achieve height adjustment of the laser marking machine 3; Furthermore, a moving clamping mechanism 7 for fixing and driving the pen holder to move is provided on the backing plate 4. The moving clamping mechanism 7 includes a driving screw rod one 71, a right-angle motor 72, a moving frame 73, a driving motor 75, and a three-jaw chuck 76. The two ends of the driving screw rod one 71 are respectively rotatably connected to both ends of an installation groove on the backing plate 4; Among them, the right-angle motor 72 is installed outside the backing plate 4 and its output shaft is connected to one end of the driving screw rod one 71. The moving frame 73 is slidably connected to sliding rails 74 on both sides of the backing plate 4 through sliders. The moving frame 73 is helically connected to the driving screw rod one 71 through a screw nut. The driving motor 75 is installed on the side of the moving frame 73 and a three-jaw chuck 76 is provided on its output shaft. An extension plate 77 is provided on each jaw of the three-jaw chuck 76, and a stop block 771 is provided on the side of each extension plate 77; The extension plate 77 and the stop block 771 further prevent the pen holder from shifting or falling off during rotation, improve clamping stability and marking accuracy, and drive the drive plate 83 to rotate through the stop block 771, so that the cleaning brush 85 cleans the gap of the extension plate 77. In addition, the fixing frame 5 is provided with a cleaning mechanism 8 for cleaning impurities on the outside of the pen holder. The cleaning mechanism 8 includes a fixing cylinder 81, a drive plate 83, a cleaning brush 85 and a tension spring 86. The fixing cylinder 81 is coaxially arranged with the three-jaw chuck 76. The lower end of the fixing cylinder 81 is provided with a discharge hole 811 to prevent impurities from accumulating in the fixing cylinder 81 and affecting the cleaning effect. The two sides of the fixing cylinder 81 are respectively connected to the two sides of the fixing frame 5 through connecting plates 82. In addition, the drive plate 83 has two symmetrically arranged in the fixed frame 5 and is hinged to the support plate 84 on the inner wall of the fixed frame 5 by a pin. The cleaning brush 85 has an arc-shaped structure and is connected to one end of the drive plate 83. The bent end of the drive plate 83 is provided with a drive inclined surface 831. One end of the tension spring 86 is connected to the inner wall of the fixed cylinder 81, and the other end of the tension spring 86 is connected to the drive plate 83.

[0026] Detailed implementation methods and principles: During operation, the height of the laser marking machine 3 is first adjusted by lifting component 6, that is, by loosening the top screw 64 and then turning the handwheel 62 at the upper end of the drive screw 61, which drives the drive screw 61 to rotate at both ends of the frame 2. The lifting seat 63 slides up and down along the slide groove 21 on the frame 2. After the height of the laser marking machine 3 is adjusted to the appropriate position, the top screw 64 on the frame 2 is tightened to complete the height positioning of the laser marking machine 3. Next, the pen holder to be processed is placed on the extension plate 77 of the three-jaw chuck 76, and the pen holder is moved so that its end contacts the stop block 771 on the extension plate 77. Then the three-jaw chuck 76 controls the jaws on it to move outward, driving the extension plate 77 to clamp and fix the pen holder. After the pen holder is clamped and fixed, the right-angle motor 72 is started. The output shaft of the right-angle motor 72 drives the drive screw 71 to rotate. The moving frame 73 moves along the slide rail 74 towards the cleaning mechanism 8, causing the clamped pen holder to move closer to the fixed cylinder 81. As the pen holder continues to move, the end of the pen holder gradually contacts the drive inclined surface 831 of the bent end of the drive plate 83 in the cleaning mechanism 8, generating a squeezing force on the drive inclined surface 831. This forces the two symmetrically arranged drive plates 83 to rotate around the pin on the inner wall support plate 84 of the fixed frame 5. The drive plates 83 drive the cleaning brush 85 connected at one end to move towards the outside of the pen holder. When the pen holder is completely inserted into the cleaning brush 85, it moves towards the outside of the pen holder. After holding the area, the drive motor 75 is then started. The drive motor 75 drives the three-jaw chuck 76 and the pen holder to rotate at a constant speed. The rotating pen holder rubs against the cleaning brush 85, cleaning the dust and other impurities on the outer wall of the pen holder. The impurities generated during the cleaning process fall into the fixed cylinder 81 and are finally discharged through the discharge hole 811 at the lower end of the fixed cylinder 81 to prevent impurities from affecting the clarity of subsequent laser marking. When the drive inclined surface 831 on the drive plate 83 finally contacts the stop block 771 on the extension plate 77, it drives the cleaning brush 85 to get closer to the extension plate 77 and cleans the impurities on the extension plate 77. After the impurities are cleaned, the output shaft of the right-angle motor 72 drives the pen holder until it moves into the marking range of the laser marking machine 3. The right-angle motor 72 stops running, and the laser marking machine 3 is started to mark the outer wall of the pen holder. The outer wall of the pen holder, which is rotating at a constant speed, is precisely marked with a laser. During the marking process, the three-jaw chuck 76 of the moving clamping mechanism 7 always maintains a stable clamping of the pen holder to prevent the pen holder from shifting or shaking, thus ensuring the marking accuracy.

[0027] After laser marking is completed, the laser marking machine 3 and drive motor 75 are turned off, and the pen holder rotation is stopped. Then, the three-jaw chuck 76 is released, releasing the clamping and fixing of the pen holder. The operator removes the marked pen holder from the three-jaw chuck 76 to complete the unloading. After unloading, the right-angle motor 72 is started, driving the moving frame 73 to move in the opposite direction along the slide rail 74 to the initial position. During the movement of the moving frame 73, the pressure of the pen holder on the driving inclined surface 831 of the drive plate 83 disappears. The drive plate 83 is reset under the tension of the tension spring 86, which drives the cleaning brush 85 to restore the initial distance between it and the fixed cylinder 81. During the rotation, the cleaning brush 85 shakes off the impurities on it.
