Description
Technical Field
[0001] This application relates to the field of automotive glass production technology, and more specifically, to a glass surface dust collection device and an automotive glass production system. Background Technology
[0002] As a crucial component of vehicles, automotive glass typically undergoes multiple processing steps before being put into use, including cutting, edging, drilling, tempering, coating, screen printing, and lamination. During production, dust, glass shards, or tiny particles inevitably adhere to the glass surface. If these impurities are not removed promptly, they can easily create defects in screen printing and coating processes, affecting appearance quality and mechanical properties. To ensure the optical performance and surface cleanliness of the finished product, dust, particles, and some oil stains are washed away using a water spray method, followed by drying to complete the cleaning process. While water spraying effectively removes contaminants, it consumes a significant amount of water in actual production, especially during long-term continuous production, where water consumption increases substantially.
[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0033] In related technologies, dust, glass shards, or tiny particles inevitably adhere to the surface of automotive glass. If these impurities are not removed in time, they can easily cause defects in processes such as screen printing and coating, affecting the appearance quality and mechanical properties. To ensure the optical performance and surface cleanliness of the finished product, dust, particles, and some oil stains are washed away from the glass surface through spray water washing, followed by drying to complete the cleaning process. Although spray water washing can effectively remove contaminants, it has the problem of large water consumption in actual production, especially during long-term continuous production, where the consumption of cleaning water increases significantly.
[0034] Therefore, this application provides a glass surface dust collection device and an automotive glass production system to solve the problems in the related technology.
[0035] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0036] Combination Figure 1 and Figure 2 As shown in the figure, this application provides an automotive glass production system, including: a glass surface dust collection device 100 and a conveyor 200. The glass surface dust collection device 100 is used to collect dust from the automotive glass conveyed on the conveyor 200. The glass surface dust collection device 100 is located upstream of the glass surface cleaning device of the automotive glass production system, so that the surface of the automotive glass can be pre-dry dusted by the glass surface dust collection device 100, thereby helping to reduce the dust on the glass surface; and then the surface of the automotive glass is cleaned by the downstream glass surface cleaning device.
[0037] Combination Figure 1 and Figure 2 As shown, the glass surface dust collection device 100 provided in this application embodiment includes: a dust collection component 101, a negative pressure generating device 102, and a dust collection component 103; the dust collection component 101 is used to be installed on the conveyor 200 of the automotive glass production system to collect dust from the automotive glass conveyed on the conveyor 200; the negative pressure generating device 102 is connected to the dust collection component 101 and is used to drive the dust collection component 101 to collect dust through negative pressure; the dust collection component 103 is connected to the negative pressure generating device 102 and is used to collect the dust collected by the dust collection component 101; wherein, the dust collection component 103 includes a fixed base 105 and a first dust collection bag 104, the first dust collection bag 104 is fixedly connected to the fixed base 105, the fixed base 105 has a first dust inlet hole, and the dust collected by the dust collection component 101 enters the first dust collection bag 104 through the first dust inlet hole.
[0038] The glass surface dust collection device 100 provided in this application embodiment has a dust collection component 101 mounted on a conveyor 200, making it compatible with the continuous conveying process of an automotive glass production system. A negative pressure generating device 102 generates negative pressure, which drives the dust collection component 101 to directly remove dust and fine particles from the glass surface. A dust collection component 103 collects the collected dust, ensuring the continuity and stability of the dust collection process. Furthermore, the dust collection component 103 helps reduce dust emissions and improve air quality in the production workshop. Because dust and fine particles are pre-removed from the glass surface, reliance on spray washing can be avoided or reduced in subsequent production processes, thereby reducing water consumption during the cleaning process.
[0039] In some embodiments, the dust collection assembly 101 may be disposed above the conveyor 200; for example, the dust collection assembly 101 may be mounted on the conveyor 200 by means of a mounting bracket (not shown) or other structure, and the dust collection assembly 101 may be fixed to the frame of the conveyor 200 by screws or welding, thereby enabling the dust collection assembly 101 to perform dust collection operation on the upper surface of the car glass.
[0040] It should be noted that in some other possible embodiments, the glass surface vacuuming device 100 may also include a lifting frame, on which the vacuuming component 101 is mounted. The lifting frame is mounted on the frame of the conveyor 200, or on the ground. In this way, the lifting frame drives the vacuuming component 101 to rise and fall, thereby adjusting the distance between the vacuuming component 101 and the automotive glass on the conveyor 200. The lifting frame may include a lifting cylinder or an electric cylinder to achieve the raising and lowering of the vacuuming component 101. Alternatively, the vacuuming component 101 may be positioned below the conveyor 200, allowing the vacuuming component 101 to also vacuum the lower surface of the automotive glass.
[0041] See Figure 3 As shown, in some embodiments, the vacuuming assembly 101 includes a vacuum hood 106, which is connected to the suction port of the negative pressure generating device 102. The suction port of the vacuum hood 106 may be elongated and is a slit structure 114. The length direction of the suction port is parallel to the width direction of the conveyor 200, which is the conveying direction of the automotive glass. For example, the width of the slit structure is 5mm-20mm, and the width of the slit structure can be 5mm, 10mm, 15mm, or 20mm.
[0042] See Figure 3As shown, in some embodiments, the vacuuming assembly 101 further includes an isolation cover 107, with the vacuum hood 106 fixed inside the isolation cover 107; this design can create a relatively sealed vacuuming environment during the vacuuming process. The isolation cover 107 can isolate the vacuuming area from the external environment, reducing the interference of external airflow on the negative pressure vacuuming effect, thereby improving the collection efficiency of the vacuum hood 106 for dust and particles on the glass surface. For example, the isolation cover 107 can be rectangular, an inverted box-shaped structure, with the vacuum hood 106 located inside the box-shaped structure. The suction inlet of the negative pressure generating device 102 is connected to the vacuum hood 106 via a pipe, and the discharge outlet of the negative pressure generating device 102 is connected to the first dust inlet of the dust collection assembly 103 via a pipe. The negative pressure generating device 102 can be fixed to the ground using anchor bolts or expansion bolts.
[0043] See Figures 4 to 7 As shown, in some embodiments, the glass surface dust collection device 100 further includes a cyclone separator 108. A negative pressure generating device 102 is connected to the dust collection assembly 101 via the cyclone separator 108. The air inlet of the cyclone separator 108 is connected to the dust collection assembly 101, and the air outlet of the cyclone separator 108 is connected to the negative pressure generating device 102. The cyclone separator 108 can also be called a cyclone separator. During dust collection, the dust-laden airflow drawn in by the dust collection assembly 101 enters the cyclone separator 108. Through the centrifugal force of the cyclone separator 108, larger dust particles are separated and settle at the settling port of the cyclone separator 108, while the cleaner airflow is discharged through the air outlet. This improves dust collection efficiency, reduces the amount of fine dust directly entering the first dust collection bag 104, extends the service life of the dust collection bag, and reduces the frequency of replacement or cleaning. Furthermore, the addition of the cyclone separator 108 reduces the burden on the negative pressure generating device 102 to directly handle the dust-laden airflow by pre-separating larger dust particles, thereby extending the service life of the negative pressure generating device 102. For example, the air inlet of the cyclone separator 108 is connected to the dust collection hood 106 via a pipe, the air outlet of the cyclone separator 108 is connected to the suction inlet of the negative pressure generating device 102 via a pipe, and the discharge outlet of the negative pressure generating device 102 is connected to the first dust inlet of the dust collection assembly 103 via a pipe. The cyclone separator 108 can be mounted on a second bracket 112, which includes multiple legs 111, which can be fixed to the ground using anchor bolts or expansion bolts.
[0044] See Figure 5As shown, in some embodiments, the glass surface dust collection device 100 further includes a discharge valve 109, which is installed at the settling port of the cyclone separator 108. The discharge valve 109 is a rotary valve or a flap valve. The discharge valve 109 is a closed discharge device, which allows airflow to enter from the air inlet and exit from the air outlet without interfering with the negative pressure effect of the negative pressure generating device 102, avoiding pressure loss and maintaining the high-efficiency dust collection capability of the dust collection component 101.
[0045] In some embodiments, the negative pressure generating device 102 is a vacuum pump or a fan; for example, the fan can be a centrifugal fan, and the vacuum pump can be a single-stage vacuum pump or a multi-stage vacuum pump.
[0046] In some embodiments, the number of dust collection components 103 is one or more; combined with Figure 1 and Figure 4 As shown, the dust collection assembly 103 is a single unit. See also... Figure 7 As shown, there are multiple dust collection components 103. When there are multiple dust collection components 103, each of the multiple dust collection components 103 is connected to the negative pressure generating device 102. That is, after the multiple dust collection components 103 are connected in parallel, they are then connected to the negative pressure generating device 102. In this way, multiple first dust collection bags 104 can be used for dust collection.
[0047] See Figure 6 As shown, in some embodiments, the glass surface dust collection device 100 further includes a first bracket 110, which is fixedly connected to the fixed base 105. Exemplarily, the first bracket 110 includes a plurality of legs 111 distributed circumferentially along the fixed base 105. One end of each leg 111 is fixedly connected to the fixed base 105; the other end of each leg 111 can be fixed to the ground using anchor bolts or expansion bolts. The fixed base 105 can be a cylindrical structure with openings at both ends, allowing the first dust collection bag 104 to be detachably fixed to each of the two axial ends of the fixed base 105. The cylindrical structure has a groove (not shown) in the circumference. The dust collection assembly 103 also includes an annular clamp 113. The annular clamp 113 can allow the first dust collection bag 104 to be sleeved on one end of the fixed base 105 and fix the first dust collection bag 104 to the fixed base 105 by the annular clamp 113. After the annular clamp 113 is locked, at least a part of the structure of the annular clamp 113 is located in the groove, which can prevent the annular clamp 113 from falling off the fixed base 105.
