Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] One embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, a conveying assembly is provided on the top of the frame. In this embodiment, the conveying assembly adopts a conveying roller structure, wherein the roller spacing in the middle section of the conveying roller structure is greater than the roller spacing on both sides, which facilitates the auxiliary roller group located below to pass through the conveying roller and the smoothing roller group above to perform clamping and smoothing actions on the glass. The vertical position changes of the smoothing roller group and the auxiliary roller group are controlled by the actuator module. According to the glass thickness, warpage, and conveying speed, the vertical spacing and contact pressure of the two wheels are automatically adjusted. The actuator module controlling the smoothing roller group is not shown in this application. Guide roller groups are provided on both sides of the conveying roller assembly to constrain the lateral displacement of the glass. A collision baffle with a concave cross-section is provided at the end of the conveying roller. Through the upper and lower aligned smoothing roller group and auxiliary roller group, the glass is effectively prevented from impacting the equipment due to concavity during the conveying process, smoothing the ripples on the glass surface, improving the accuracy of subsequent processing, and is suitable for glass of various thicknesses and sizes. It has strong compatibility, reduces the breakage rate, and improves the yield of the production line.
[0026] like Figure 4 As shown, the surface of the smoothing wheel assembly 3 is made of soft rubber 31, and a spring buffer structure 32 is provided inside. When it comes into contact with the glass surface, it automatically adapts to its curvature to achieve smoothing.
[0027] like Figure 3 As shown, the auxiliary wheel set 4 and the smoothing wheel set 3 are aligned vertically and are driven to lift by a servo motor. The surface of the auxiliary wheel set 4 is covered with a silicone layer, and the wheel axle is connected to the frame by a spring. The wheel spacing is electrically adjustable and is used to lift the glass from below to prevent it from denting. A lifting mechanism is installed at the bottom of the auxiliary wheel set and is driven by a servo motor at the corresponding position.
[0028] like Figure 6 As shown, the outer layer of the groove of the anti-collision baffle 6 is a polyurethane elastic layer 61, and the air pressure damping cavity 62 is embedded in the inner side of the polyurethane elastic layer 61. The side wall of the air pressure damping cavity 62 is provided with airflow holes 621. When the glass is impacted, it sinks into the groove, the elastic layer absorbs the kinetic energy, and the damping cavity slowly releases the pressure through the airflow holes to achieve "soft stop". Through the multiple buffer structure, the impact kinetic energy is absorbed and the impact force is attenuated.
[0029] The sensor module 7 includes a laser rangefinder sensor mounted on the frame above the conveyor assembly 2 and a pressure sensor 33 mounted inside the smoothing wheel assembly. The laser rangefinder sensor detects the glass thickness, and the pressure sensor detects the contact pressure. The glass status parameters are collected in real time. An encoder is installed at the drive motor of the conveyor assembly 2. The sensor module 7 and the encoder are controlled by a control module composed of a PLC.
[0030] The actuator module 8 consists of two servo motors that drive the smoothing wheel set 3 and the auxiliary wheel set 4 to lift and lower, respectively, to achieve rapid response to control commands. The overall communication module adopts CAN bus to ensure low latency synchronization of <10ms.
[0031] like Figure 5 As shown, the pressure sensor 51 inside the guide wheel assembly 5 is electrically connected to the drive motor of the control transmission assembly 2. When the glass is being transported, the guide wheel assembly rolls close to the edge of the glass to eliminate lateral displacement. If the glass is tilted, the guide wheel assembly is compressed and retracts, triggering the pressure sensor, which in turn activates the deceleration device and retracts to smooth out the wheel assembly and auxiliary wheel assembly, preventing secondary extrusion deformation.
[0032] The working principle of this embodiment is as follows: After the system is powered on, the smoothing wheel set and the auxiliary wheel set return to their respective extreme positions, automatically homing to establish zero coordinates. The PLC reads the current standard glass thickness and writes it into the register as the reference value. The laser rangefinder measures the actual thickness before the glass enters the workstation and compares it with the reference value to form a deviation δd. The control system obtains the target height through PID calculation and controls the lifting and lowering through the servo motor to meet the following conditions: the target height of the smoothing wheel set = reference height - δd / 2, and the target height of the auxiliary wheel set = reference height + δd / 2. After the actuator module moves, the encoder provides real-time feedback of position parameters to ensure that the error is ≤0.05mm. The pressure sensor detects the contact force between the wheel set and the glass. If the pressure exceeds the tolerance, the PLC fine-tunes the position of the servo motor until it stabilizes within the set range. When the glass hits the guide wheel set, the pressure sensor triggers an interrupt signal, the conveyor component decelerates to a stop, the servo motor reverses, and the alarm light flashes to wait for manual reset. When the system detects that a section of the glass has sagged, it controls the movement of the smoothing wheel set and the auxiliary wheel set according to the sag distance. The glass is clamped and passes smoothly without collision throughout the process.
[0033] Several points need to be clarified: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly, and can refer to mechanical or electrical connections, or internal connections between two components, or direct connections. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships, and the relative positional relationships may change when the absolute position of the described objects changes. Second, in this document, relational terms such as "first" and "second" are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities.
