Description

Technical Field

[0001] This utility model relates to the field of insulating glass production technology, specifically a glass positioning device for an insulating glass production line. Background Technology

[0002] Insulating glass, as a highly efficient and energy-saving building material, is widely used in building doors, windows, and curtain walls due to its excellent heat insulation and sound insulation properties. Its core structure consists of two or more glass panes separated by spacers and double-sealed around the perimeter with sealant, forming a dry, still air or inert gas cavity. In the automated production process of insulating glass, the precise positioning of the glass panes is a key factor affecting the assembly accuracy and product quality.

[0003] Traditional positioning devices typically employ a single fixing method, such as fixation via central area adsorption or mechanical clamping at the four corners. While center-fixed devices facilitate center positioning of the glass, they struggle to effectively constrain edge displacement in large-sized glass pieces. Corner clamping devices, while limiting overall displacement, are prone to glass breakage due to localized stress and cannot accommodate special processes requiring central support, such as drilling and coating. Furthermore, existing positioning devices lack integrated automatic flipping functionality, leading to inefficient process connections and hindering improvements in production line automation.

The bidirectional screw 403 drives... The movable clamping plate 402 can adapt to the glass thickness, disperse local stress, and avoid cracking. The negative pressure air source 512 evenly distributes the adsorption force through the air extraction port, suppressing the deformation of the glass center and adapting to the process requirements of drilling, coating, etc. The gear 409 works in conjunction with the first rack 410 and the first cylinder 411 to drive the mounting frame 2 to flip as a whole, eliminating the manual handling link. The flipping process does not require disassembling the glass and can directly connect to the next process on the production line, improving the automation rate and work efficiency. The first and second bidirectional lead screws 407 drive the four sets of adjusting rods to vertically link and synchronously adjust the position of the clamping block 401, which is compatible with different sizes of glass. The clamping plate 402 can be independently fine-tuned in both directions to ensure balanced clamping force and prevent single-point overload. The second cylinder 506 pushes the second rack 505 and the gear ring 504 mechanism to drive the adjusting plate 503 to rotate. The guide rod 509 slides along the arc-shaped guide groove 507, so that the three sets of vacuum suction cups 510 can extend and retract radially synchronously, accurately adapting to the curvature or size changes of the glass center area.

[0027] In this embodiment, reference Figures 2-6As shown, a circulating air pump 6 is fixedly installed on both the base frame 1 and the mounting base 3. The air outlets of the first cylinder 411 and the second cylinder 506 are connected to the air inlets of the circulating air pump 6 through purification pipes.

The two ends of the second bidirectional lead screw 407 pass through the two sets of second adjusting rods 405 and are threadedly connected to the two sets of second adjusting rods 405 respectively. The joint rod 405 is threaded. The motor in the mounting bracket 2 drives the corresponding first bidirectional lead screw 406 or second bidirectional lead screw 407 to rotate. Under the position limitation of the mounting bracket 2, the two sets of symmetrically distributed first adjusting rods 404 and two sets of symmetrically distributed second adjusting rods 405 slide synchronously inward or outward. The four sets of clamping blocks 401 move synchronously along the two sets of first adjusting rods 404 and two sets of second adjusting rods 405 to the preset positions at the four corners of the glass. The motor on the clamping block 401 is started to drive the corresponding bidirectional screw 403 to rotate, driving the two sets of clamping plates 402 to adapt to the glass thickness clamping. Tightening and dispersing local stress, the first cylinder 411 pushes the first rack 410 to move linearly, meshing with the first gear 409 on the mounting shaft 408 to rotate. The mounting bracket 2 drives the fixed glass to rotate 180° and directly transport it to the next process. The rotation process does not require disassembling the glass, eliminating the manual handling link. The exhaust end of the first cylinder 411 and the second cylinder 506 outputs exhaust gas, which enters the circulating air pump 6 after being filtered by the purification pipeline. The circulating air pump 6 pressurizes the exhaust gas and re-injects it into the cylinder intake end through the high-pressure air pipe, realizing the closed-loop reuse of compressed air and reducing energy consumption by more than 40%.

The guide rods 509 are slidably connected to the adjusting plate 503 through the guide grooves 507. The threaded rod 501 rotates, driving the mounting base 3 to slide below the center of the glass. The second cylinder 506 pushes the second rack 505 to move linearly, meshing with the gear ring 504 on the adjustment plate 503 to rotate. The three sets of arc-shaped guide grooves 507 of the adjustment plate 503 drive the guide rod 509 to slide radially, causing the three sets of adjustment frames 508 to extend and retract synchronously along the guide rail 502. The vacuum suction cup 510 precisely fits the center area of ​​the glass. The negative pressure air source 512 is activated, and the air extraction port simultaneously evacuates the three sets of interconnected vacuum suction cups 510 through the connecting pipe 511, generating a uniform suction force to suppress the deformation of the center of the glass. The surrounding clamping blocks 401 work together with the central suction cup. The clamping blocks 401 restrict the displacement of the glass edge, and the suction cup provides central support, adapting to the needs of drilling and coating processes.

[0029] In this embodiment, during operation, the motor in the mounting frame 2 drives the corresponding first bidirectional lead screw 406 or second bidirectional lead screw 407 to rotate. Under the position limitation of the mounting frame 2, the two sets of symmetrically distributed first adjusting rods 404 and two sets of symmetrically distributed second adjusting rods 405 slide synchronously inward or outward. The four sets of clamping blocks 401 move synchronously along the two sets of first adjusting rods 404 and two sets of second adjusting rods 405 to the preset positions at the four corners of the glass. The motor on the clamping block 401 is started to drive the corresponding bidirectional screw 403 to rotate, driving the two sets of clamping plates 402 to clamp the glass according to its thickness and disperse local stress.

The mounting frame 2 drives the fixed glass to rotate 180° and directly transport it to the next process. The rotation process does not require disassembling the glass, eliminating the manual handling link. The exhaust ends of the first cylinder 411 and the second cylinder 506 output... The exhaust gas, after being filtered through the purification pipeline, enters the circulating air pump 6. The circulating air pump 6 pressurizes the exhaust gas and re-injects it into the cylinder inlet through the high-pressure air pipe, realizing closed-loop reuse of compressed air and reducing energy consumption by more than 40%. The internal thread rod 501 of the base frame 1 rotates, driving the mounting base 3 to slide to below the center of the glass. The second cylinder 506 pushes the second rack 505 to move linearly, meshing with the gear ring 504 on the adjustment plate 503 to rotate. The three sets of arc-shaped guide grooves 507 of the adjustment plate 503 drive the guide rod 509 to slide radially, so that the three sets of adjustment frames 508 can extend and retract synchronously along the guide rail 502. The vacuum suction cup 510 precisely fits the center area of ​​the glass.
