Description

Technical Field

[0001] The utility model relates to a laser engraving device, in particular to a full-automatic laser engraving device for a glass panel. Background Art

[0002] Laser engraving on glass panels is a glass panel processing method that uses the light energy of a laser beam to cause chemical and physical changes in the surface material to leave marks, or uses light energy to burn away part of the material to reveal the desired etched graphics and text.

[0003] One of the most significant advantages of laser engraving glass panels is its precision. Laser engraving is highly accurate, allowing for incredibly detailed designs. Furthermore, laser engraving is fast and efficient, making it a cost-effective option for mass production. Laser engraving is also environmentally friendly, as it produces no harmful chemicals or waste. Common laser engraving equipment includes mechanical engravers and laser engraving machines.

[0004] Common mechanical engraving machines on the market often require manual feeding during laser engraving, and there will be a rough position correction step after the feeding is completed. However, the accuracy of the correction is very low, and laser engraving position errors often occur, resulting in a high defective rate. Summary of the Invention

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0044] See also Figures 1 to 8 As an embodiment of the present invention, the glass panel fully automatic laser engraving device includes a chassis 1 and a laser engraving device 2 provided on the chassis 1;

[0045] The chassis 1 is mounted with a mounting plate 102; a plurality of support rods 11 are slidably mounted on the mounting plate 102, and the support rods 11 are symmetrical in pairs; a clamping mechanism is provided on the support rods 11, and the clamping mechanism can clamp the glass panel;

[0046] The mounting plate 102 is provided with a transverse centering mechanism connected to the support rods 11, and the transverse centering mechanism can drive the mutually symmetrical support rods 11 to move closer to each other;

[0047] The chassis 1 is provided with two groups of longitudinal centering mechanisms, and the longitudinal centering mechanisms are connected to the contact plates 9 . The longitudinal centering mechanisms can drive the contact plates 9 to move closer to or away from each other.

[0048] In this embodiment, the operator first clamps the glass panel on the support rods 11 using the clamping mechanism. Under the action of the transverse centering mechanism, the mutually symmetrical support rods 11 will move closer to each other, so that the supported glass panel tends to be centered in the transverse direction.

[0049] Under the action of the longitudinal centering mechanism, the contact plates 9 will approach each other. In the process of approaching each other, the contact plates 9 will contact and squeeze the glass panel. In the process of contact between the two, the clamping mechanism releases the clamping of the glass panel. At this time, the glass panel will be displaced on the clamping mechanism under the joint action of the transverse centering mechanism and the longitudinal centering mechanism, so that the glass panel is aligned with the center of the mounting plate 102. Afterwards, the longitudinal centering mechanism will drive the contact plates 9 to move away from each other, so that the clamping mechanism will re-clamp the centered glass panel.

[0050] Finally, the operator will start the laser engraving device 2 to perform laser engraving on the center glass panel.

[0051] By cooperating with the clamping mechanism, the horizontal centering mechanism and the vertical centering mechanism, the glass panel is aligned with the center of the mounting plate 102, which can make the position of the laser engraving by the laser engraver 2 more accurate, thereby avoiding the increase of the defective rate of the processing by laser engraving without position correction.

[0052] As a further solution of the present invention, connecting rods 101 are installed on both sides of the chassis 1 in a lateral direction, a sliding frame 3 is slidably installed on the connecting rods 101 , and the laser engraving device 2 is slidably installed on the sliding frame 3 .

[0053] In this embodiment, the laser engraving device 2 can slide on the sliding frame 3, which in turn can slide on the connecting rod 101, allowing the laser engraving device 2 to laser engrave any position on the mounting plate 102. The laser engraving device 2 is initially aligned with the center of the mounting plate 102, that is, a processing coordinate system is established with the center of the mounting plate 102 as the origin. When laser engraving a glass panel, after inputting the coordinates of the position to be laser engraved into the laser engraving system, the laser engraving device 2 slides on the sliding frame 3 and the sliding frame 3 slides on the connecting rod 101 to complete the positioning.

[0054] As a further solution of the present invention, the clamping mechanism includes a lower clamping plate 12 installed on the support rod 11; a second sliding groove 1102 is opened on the support rod 11, and an upper clamping plate 13 is slidably engaged on the second sliding groove 1102; a first spring 14 is installed in the second sliding groove 1102.

[0055] In this embodiment, in an initial state, the upper clamping plate 13 is in contact with the lower clamping plate 12 under the action of the first spring 14 .

[0056] The operator applies an external force to the upper clamping plate 13 away from the lower clamping plate 12, so that the upper clamping plate 13 slides in the second slide groove 1102 away from the lower clamping plate 12. At this time, the first spring 14 will be compressed; then the operator places the glass panel on the lower clamping plate 12 and then removes the external force. Under the elastic force of the first spring 14, the upper clamping plate 13 will slide toward the lower clamping plate 12 in the second slide groove 1102. Finally, the glass panel will be clamped by the upper clamping plate 13 and the lower clamping plate 12. The first spring 14 provides sufficient clamping force to prevent the glass panel from moving.

[0057] As a further solution of the present invention, the horizontal centering mechanism includes a shift rod 10 installed on the mounting plate 102, and a telescopic sleeve 1001 is installed on the shift rod 10, and a telescopic column 1101 connected to the support rod 11 is slidably engaged in the telescopic sleeve 1001; a second spring 16 connected to the telescopic column 1101 is installed in the telescopic sleeve 1001; a first sliding groove 103 is opened on the mounting plate 102; and a second slider 15 connected to the support rod 11 is engaged in the sliding rod in the first sliding groove 103.

[0058] In this embodiment, the initial position of the second slider 15 is located at the end of the first slide groove 103 away from the gear lever 10. At this time, the distance between the two symmetrical second sliders 15 is much smaller than the horizontal length of the glass panel. After all the clamping mechanisms clamp the glass panel, the glass panel will squeeze the support rod 11, causing the two symmetrical support rods 11 to move away from each other.

[0059] As the two support rods 11 move away from each other, the telescopic column 1101 slides within the inner housing of the telescopic sleeve 1001, compressing the second spring 16. The second slider 15 also slides within the first slot 103 toward the shift rod 10. Once stabilized, the elastic force of the second spring 16 forces the support rods 11 toward each other. Because the elastic force provided by the second spring 16 is constant, the horizontal midpoint of the glass panel, once stabilized, is located at the exact center of the symmetrical support rods 11, i.e., the exact horizontal center of the mounting plate 102.

[0060] As a further solution of the present invention, the longitudinal centering includes a motor 4 installed on the chassis 1, a screw rod 5 is connected to the output end of the motor 4, and two internally threaded sleeves 6 are threadedly connected to the screw rod 5; a resistance plate 9 is installed on the internally threaded sleeve 6; a first slider 7 is installed on the resistance plate 9; and a guide rod 8 is installed on the chassis 1 that is slidably connected to the first slider 7.

[0061] In this embodiment, after the lateral centering mechanism completes its operation, the motor 4 is started; the rotating motor 4 drives the screw 5 to rotate, and because the threads at the two ends of the screw 5 have opposite directions, the internally threaded sleeves 6 at both ends approach each other on the screw 5, thereby driving the contact plates 9 to approach each other on the mounting plate 102. The approaching contact plates 9 contact the glass panel and apply two opposite and equal thrusts to the glass panel in the longitudinal direction. This thrust acts on the glass panel so that the longitudinal center of the glass panel is ultimately located at the exact center of the two contact plates 9, that is, at the longitudinal center of the mounting plate 102.

[0062] At the same time, when the contact plates 9 approach each other, the first slider 7 slides on the guide rod 8 to ensure that the contact plates 9 are always vertical to the mounting plate 102 during the movement, so as to prevent the tilted contact plates 9 from pushing the glass panel to the wrong position.

[0063] As a further solution of the present invention, the longitudinal centering mechanism also includes a third sliding groove 1501 opened on the second slider 15, and a sliding rod 1301 slidingly connected to the third sliding groove 1501 and the second sliding groove 1102 is installed on the upper clamping plate 13; a trigger plate 17 is connected between the first slider 7 and the internal threaded sleeve 6.

[0064] In this embodiment, before the contact plate 9 contacts the glass panel, the internal threaded sleeve 6 and the first slider 7 will drive the trigger plate 17 to slide toward the slide bar 1301. When the trigger plate 17 contacts the slide bar 1301, the inclined surface guard on the trigger plate 17 will interfere with the inclined surface at the bottom of the slide bar 1301, and push the slide bar 1301 to slide on the trigger plate 17, so that the slide bar 1301 will slide in the second slide groove 1102 and the third slide groove 1501 toward the upper clamping plate 13 (the second slide groove 1102 and the third slide groove 1501 are connected), thereby pushing the upper clamping plate 13 to slide away from the lower clamping plate 12, and the first spring 14 will be compressed, so that the clamping mechanism releases the clamping of the glass panel. After the end of the slide rod 1301 enters the flat surface of the trigger plate 17 from the inclined surface of the trigger plate 17, the slide rod 1301 will maintain the position of the compressed first spring 14 unchanged, so that after the contact plate 9 contacts the glass panel, there is no restrictive force on the glass panel, which facilitates the contact plate 9 and the support rod 11 to adjust the position of the glass panel, thereby further ensuring the center alignment of the central mounting plate 102 of the glass panel.

[0065] After the clamping mechanism is released, the support rod 11 will be tightly attached to both sides of the glass panel under the action of the second spring 16 to further ensure that the glass panel is aligned with the center of the mounting plate 102 in the horizontal direction.

[0066] When the glass panel is centered, the motor 4 drives the screw 5 to rotate in the opposite direction, so that the contact plates 9 move away from each other, so that the trigger plate 17 is out of contact with the slide bar 1301, and under the action of the first spring 14, the clamping mechanism will clamp the glass panel again.

[0067] The longitudinal centering mechanism can align the longitudinal center of the glass panel with the center of the mounting plate 102, and during the alignment process, the clamping mechanism will release the clamping mechanism to reduce the resistance encountered by the glass panel during position adjustment, thereby further ensuring that the adjusted center position of the glass panel is aligned with the center of the mounting plate 102, thereby reducing the defective rate of laser engraving.

[0068] As a further solution of the present invention, a heat dissipation slot is provided on the chassis 1 , and the heat dissipation slot can reduce the temperature of the chassis 1 .

[0069] In this embodiment, since laser engraving generates a relatively high temperature, the chassis 1 can dissipate heat through the heat dissipation slots to ensure the normal operation of the laser engraving device.

[0070] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
