Description

Technical Field

[0001] This utility model belongs to the field of glass processing technology, specifically relating to a glass pre-positioning device in front of a tempering furnace. Background Technology

[0002] The existing tempering furnace front positioning relies on the furnace's own lifting cylinder (to lift the aluminum profile) in conjunction with manual operation: after the glass is transferred to the furnace front positioning area, the lifting cylinder lifts the aluminum profile and the glass together. The operator needs to manually move and adjust the position of the nylon block on the aluminum profile, and then put the glass close to the preset nylon block to complete the positioning; when the furnace body cycle signal is triggered, the lifting cylinder descends, and the glass falls onto the transmission roller and enters the furnace.

[0003] This method has significant drawbacks: First, when changing production, the nylon blocks need to be manually moved to adapt to the new glass specifications, which is difficult and time-consuming (adjusting a single specification takes more than 5 minutes), seriously affecting production efficiency; Second, the positioning accuracy depends on manual operation experience, and the adjustment error of the nylon blocks can easily lead to deviations in the front-back, left-right, and angle of the glass, which in turn leads to scrap in the furnace and low product qualification rate; Third, manual adjustment requires full-time monitoring, which is labor-intensive, and with a furnace cycle of 7-10 seconds per block, personnel are prone to fatigue, leading to positioning errors and further increasing production risks. Utility Model Content

[0028] Furthermore, the output shaft end of the X-axis servo motor 7 is provided with a drive wheel 21, and the other end of the lower moving frame 4 opposite to the X-axis servo motor 7 is provided with a driven wheel 22. The annular synchronous belt 9 is sleeved on the drive wheel 21 and the driven wheel 22, and the annular synchronous belt 9 is parallel to the transmission roller 12.

[0029] Furthermore, the output shaft end of the Y-axis servo motor 8 is provided with a driving wheel 25, and the other end of the lower moving frame 4 opposite to the Y-axis servo motor 8 is provided with a driven wheel 26. The annular synchronous belt 10 is sleeved on the driving wheel 25 and the driven wheel 26, and the annular synchronous belt 10 is perpendicular to the transmission roller 12. The clamping mechanism 2 includes a guide rail 2 located at the bottom of the lower movable frame 4. The guide rail 2 is provided with a guide block 27.

[0032] This invention does not require an additional lifting structure; it relies directly on the lifting cylinder built into the furnace. When the glass is transported to the positioning area in front of the furnace, the furnace control system triggers the lifting cylinder to lift the glass synchronously (disengaging it from the transmission roller), providing working space for X-axis and Y-axis clamping and positioning, and maintaining consistency with the furnace lifting rhythm throughout the process.

[0033] After being lifted into position, the X-axis servo motor drives the annular synchronous belt to move horizontally in both forward and reverse directions. By bringing the two nylon blocks closer together, the glass is quickly clamped and positioned in the X-axis direction (positioning accuracy ±0.5mm). After positioning, the synchronous belt immediately retracts to avoid interfering with subsequent actions.

[0034] The Y-axis adopts an independent servo synchronous belt structure consistent with the X-axis (without cross-linking). The Y-axis servo motor drives the second ring synchronous belt to move in the horizontal and vertical directions. By the relative proximity of the second nylon block on the second ring synchronous belt, the glass is positioned in the Y-axis direction in coordination with the X-axis.

[0035] This invention is linked to the furnace's own control system. When the furnace sends a cycle signal of 7-10 seconds per piece, the X-axis and Y-axis positioning actions are quickly completed during the lifting phase (time ≤ 2 seconds). After the cycle is triggered, the furnace's own lifting cylinder descends, and the glass falls onto the transmission roller and enters the furnace. At the same time, the next piece of glass is transferred to the positioning area, and the lifting cylinder lifts again, starting a new round of positioning cycle, achieving a seamless connection between "lifting-positioning-lowering into the furnace".
