Description

Technical Field

[0001] This invention relates to the field of insulating glass production, and in particular to a horizontal laser descaling and sandblasting machine for insulating glass production. Background Technology

[0002] Glass coating removal aims to precisely remove various thin film layers formed on the glass surface due to coating processes, such as the metallic film layer on low-emissivity coated glass. This operation can restore the original optical and physical properties of the glass, providing a good foundation for subsequent processing such as cutting, edging, and tempering, avoiding processing defects caused by the coating layer, and meeting the glass purity requirements of different scenarios. Sandblasting, on the other hand, uses high-speed jets of sand particles to impact the glass surface, giving the glass a unique frosted texture and soft light transmission. It not only enhances the anti-slip and anti-glare effects of the glass, improving safety and visual comfort, but also effectively protects privacy. It is widely used in architectural decoration, furniture design, and other fields, adding aesthetics and practicality to glass products.

Currently, the industry generally uses chemical cleaning or mechanical polishing. However, chemical cleaning presents environmental pollution and waste liquid treatment problems, while mechanical polishing is prone to causing scratches on the glass surface, poor consistency, and low processing efficiency. Although laser technology has been gradually applied to the glass processing field in recent years, existing vertical laser equipment has problems such as large footprint, insufficient glass positioning accuracy, and difficulty in dust collection, making it difficult to meet the stringent requirements of modern production lines for high efficiency, high precision, and clean production.

[0013] In summary, the present invention provides a horizontal laser film removal and sandblasting machine for insulating glass production, which has the following beneficial effects: 1. This horizontal laser decoction and sandblasting machine for insulating glass production uses a high-precision three-axis motion system composed of gears, racks, electric slide rails, and a lifting mechanism to drive the laser head to quickly and accurately position itself in three-dimensional space, meeting the processing requirements of complex paths.

Detailed Implementation

[0018] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Example

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a horizontal laser film removal and sandblasting machine for insulating glass production includes a frame 1, a controller 2 and a glass placement rack 3. A dust collection mechanism 4 is provided on the inner side of the frame 1, and a laser generating mechanism 5 is provided on the top of the frame 1. The vacuuming mechanism 4 includes a vacuum bridge 401, a vacuum hood 402 slidably connected to the top of the vacuum bridge 401, a first connecting rod 403 fixedly connected to the outside of the vacuum hood 402, a second connecting rod 404 fixedly connected to the side of the first connecting rod 403 away from the vacuum hood 402, a corrugated pipe 405 fixedly connected to the front of the vacuum hood 402, a dust collection box 406 fixedly connected to the inside of the frame 1, a vacuum fan 407 fixedly connected inside the dust collection box 406, and an electrostatic adsorption plate 408 inserted inside the dust collection box 406.

[0020] like Figure 1 and Figure 2 As shown, the controller 2 is fixedly connected to the outside of the frame 1. Fixing the controller 2 to the outside of the frame 1 makes it easy for operators to access and operate, improving operational safety and maintenance convenience. The glass placement rack 3 is fixedly connected to the inside of the frame 1, ensuring that the glass placement rack 3 and the frame 1 form a rigid structure, providing a stable and reliable support reference surface for the glass. There are two glass placement racks 3, which are evenly distributed. Using two evenly distributed glass placement racks 3 can provide balanced and sufficient support for glass panels of different sizes, preventing the glass from deforming or breaking due to suspension or insufficient support.

[0021] like Figure 1, Figure 3 and Figure 4 As shown, the suction bridge 401 is located inside the frame 1 and below the glass shelf 3. Positioning the suction bridge 401 directly below the dust source provides the optimal structural position for efficient dust collection, conforming to the natural law of dust falling under gravity. The bottom of the suction hood 402 is fixedly connected to a positioning block, and the top of the suction bridge 401 is provided with a positioning groove that matches the movement trajectory of the positioning block. Through the sliding pair design of the positioning block and the positioning groove, the suction hood 402 can move flexibly and smoothly along the suction bridge 401, ensuring the accuracy of the dust collection position.

[0022] like Figure 3 and Figure 4 As shown, there are two first connecting rods 403, symmetrically distributed on the left and right sides of the dust cover 402. The symmetrical arrangement of the first connecting rods 403 on both sides can pull and fix the dust cover 402 in a balanced manner from both sides, avoiding the torsion or jamming that may occur with single-point connection, making the movement more stable. The first connecting rods 403 are made of flexible material, which has a certain bending and buffering capacity, can adapt to small position deviations and vibrations, effectively absorb the impact of movement, and prevent damage or movement interference that may be caused by rigid connection of the mechanism. There are two second connecting rods 404, which are fixedly connected to the opposite sides of the two first connecting rods 403 respectively. The second connecting rods 404 connect the first connecting rods 403 on the left and right sides into an integral frame, which enhances the rigidity and stability of the entire dust cover 402 connection and ensures the accuracy of its synchronous movement with the drive component above.

[0023] like Figure 3 As shown, the suction fan 407 is fixedly connected to the inner bottom wall of the dust collection box 406. Fixing the suction fan 407 to the bottom of the dust collection box 406 allows the dust to be sucked in and directly enter the collection area downwards. The airflow path is reasonable, which helps to prevent the dust from being re-entrained in the box. The right side wall of the dust collection box 406 has no fewer than three air inlets that are distributed vertically. Setting multiple vertically distributed air inlets increases the cross-sectional area for airflow entry, which can effectively reduce wind resistance and improve suction efficiency.

[0024] like Figure 3 and Figure 5As shown, there are two electrostatic adsorption plates 408 arranged vertically. The use of double-layer electrostatic adsorption plates 408 constitutes a two-stage filtration system, which greatly improves the capture efficiency of fine dust particles, especially light floating particles, ensuring that the discharged air is clean. The outer side of the electrostatic adsorption plate 408 is fixedly connected to a handle extending to the outside of the dust collection box 406. The external handle design allows the operator to easily pull out the electrostatic adsorption plate 408 for cleaning or replacement without opening the box or touching the internal dirt, making maintenance very convenient. The top air inlet is located below the bottom electrostatic adsorption plate 408, ensuring that all dust-laden airflow must pass through the bottom electrostatic adsorption plate 408 for filtration before flowing upward, achieving effective treatment of all inhaled dust, avoiding airflow short-circuiting, and ensuring filtration effect.

[0025] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the laser generating mechanism 5 includes a rack plate 501, a mounting base 502 slidably connected to the top of the frame 1, a servo motor 503 fixedly connected to the top of the mounting base 502, a gear 504 fixedly connected to the output shaft of the servo motor 503, an electric slide rail 505 fixedly connected to the top of the mounting base 502, an electric slider 506 slidably connected to the outside of the electric slide rail 505, a lifting mechanism 507 fixedly connected to the outside of the electric slider 506, and a laser head 508 detachably connected to the outside of the lifting mechanism 507. This mechanism integrates the gear 504, rack plate 501, electric slide rail 505, and lifting mechanism 507, which together constitute a high-precision three-axis motion system, enabling the laser head 508 to be quickly and accurately positioned at any position in three-dimensional space, meeting the needs of complex processing paths.

[0026] like Figure 1 , Figure 2 and Figure 6 As shown, rack plates 501 are fixedly connected to the top of the frame 1. There are two rack plates 501, which are symmetrically distributed from left to right. There are two mounting seats 502, which are located above the two rack plates 501 respectively. Gears 504 mesh with rack plates 501. The double-sided symmetrical gear 504 and rack plate 501 drive system provides double-sided balanced driving force for mounting seats 502, completely avoiding the torsion and asynchrony problems that may be caused by single-sided drive, and ensuring the extremely high rigidity and smooth movement of the gantry structure during high-speed and long-stroke movement.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, the laser head 508 is located above the glass mounting bracket 3, clearly defining the top-down processing method of the laser head 508 to achieve a standard layout for precise alignment and stable energy transmission. The vacuum bridge 401 is fixedly connected to the bottom of the electric slide rail 505 via two symmetrically distributed vertical rods. The two vertical rods are located on opposite sides of the two glass mounting brackets 3, setting the support points of the vacuum bridge 401 on the outside of all glass mounting brackets 3. This ensures that the support structure of the vacuum bridge 401 and its vacuum hood 402 will not collide with the fixed glass mounting brackets 3 when they move back and forth. The two second connecting rods 404 are respectively connected to the electric slide rail 505. The left and right sides of block 506 are fixedly connected, directly binding the left and right movement of the dust hood 402 to the electric slider 506. At the same time, the forward and backward movement is transmitted through the flexible first connecting rod 403, thus cleverly realizing the complete synchronous movement of the dust hood 402 and the laser head 508 in the left and right and forward and backward directions. The controller 2 is connected to the servo motor 503, electric slide rail 505, electric slider 506 and lifting platform 507 respectively. The controller 2 coordinates the actions of all moving parts in a unified manner, realizing the automation and intelligence of the whole machine processing. It can accurately execute complex processing programs and ensure the coordination between laser processing and dust collection.

[0028] In operation, the operator first places the insulating glass plate to be processed stably on two glass placement racks 3 fixed at equal intervals to the inside of the frame 1. Then, the operator starts the equipment and selects the processing program via the controller 2 fixed to the outside of the frame 1. The servo motor 503 fixed to the top of the mounting base 502 starts, driving the gear 504 on its output shaft to mesh with the rack plates 501 symmetrically distributed on the top of the frame 1, thereby moving the entire mounting base 502 and its components in the left-right direction. At the same time, the electric slide rail 505 on the top of the mounting base 502 drives the electric slider 506 on its outside to move in the front-back direction. The lifting mechanism 507 fixed to the outside of the electric slider 506 is responsible for precise positioning in the up-down direction, and finally moves the laser head 508, which is detachably connected to its outside, to the processing starting point above the glass. The laser head 508 emits laser according to the preset path to remove the film or sandblast the glass surface. During this process, the suction fan 407 fixed to the bottom wall of the dust collection box 406 works to generate negative pressure, and the dust is drawn out by the suction. The vacuum hood 402, which is close to the bottom surface of the glass, is captured. Two second connecting rods 404 are directly fixed to the left and right sides of the electric slider 506 that drives the laser head 508 to move back and forth, thereby transmitting the back and forth motion to the vacuum hood 402. The entire vacuum bridge 401 is fixedly connected to the bottom of the electric slide rail 505 that drives the laser head 508 to move left and right through two symmetrical vertical rods located on the opposite side of the glass mounting bracket 3. This achieves completely synchronized movement of the vacuum hood 402 and the laser head 508 in the left and right and back and forth directions. To ensure that the suction port is always aligned with the processing point, the suction hood 402 slides in a positioning groove on the top of the suction bridge 401, which is fixed inside the frame 1 and located below the glass placement rack 3, through its bottom positioning block, ensuring that its movement trajectory is accurate. The airflow carrying dust is sucked into the dust collection box 406 through the corrugated pipe 405 fixedly connected to the front of the suction hood 402. The airflow passes through a two-stage filtration system consisting of two electrostatic adsorption plates 408 distributed vertically, in which tiny dust particles are efficiently captured, and the purified air is finally discharged.

[0029] It should be noted that although the horizontal laser film removal and sandblasting machine described in this application is illustrated using the insulated glass production industry as an example, its technical solution is not limited to the insulated glass industry. Its high-precision laser processing capability, synchronous and efficient dust collection system, and stable horizontal structural design make it equally applicable to other fields requiring film removal or sandblasting treatment of flat glass surfaces, such as the electrical glass processing industry.
