Description

Technical Field

[0001] This utility model relates to the panel industry, and in particular to a glass substrate alignment device for the transmission and positioning of glass substrates in the panel industry. Background Technology

[0002] With the upgrading of electronic products such as televisions, mobile phones, and tablets, the usage of glass substrates is increasing year by year, thus requiring the cutting and polishing of various types of glass substrates. Alignment and positioning of the glass substrates are crucial for subsequent cutting and polishing processes.

[0003] However, in existing alignment mechanisms, the roller / roller positions are fixed, making them prone to rigid collisions when in contact with the glass substrate. In addition, after prolonged use, the roller surface may wear down or accumulate hard particles, which can easily scratch or cut the brittle glass substrate surface under rigid contact, resulting in damage to more than 35% of the glass substrate during the alignment process. This also affects the service life of the alignment mechanism. Utility Model Content

[0036] Example 1

[0037] like Figure 1 and 2 As shown, this utility model discloses a glass substrate alignment device, including: a base 10, a positioning roller 20 and an elastic rotation device 30.

[0038] The base 10 has a cross-shaped structure, with one end connected to the alignment machine.

[0039] There are two positioning rollers 20, which are symmetrically and vertically mounted on the base 10 to abut the bottom edge of the glass substrate. The surface of the positioning rollers 20 is covered with a polyurethane elastic layer with a thickness of 3mm and a Shore A of 70-80 degrees to protect the bottom edge of the glass substrate and prevent scratches.

[0040] like Figure 3 As shown, the elastic rotary device 30 is rotatably installed in the front center region of the base 10.

[0041] Specifically, the elastic rotary device 30 includes a lower plate 31, an upper plate 32, a connecting rod assembly 33, a rotating handle 34, a bearing 35, an alignment roller 36, and a reset mechanism.

[0042] The lower plate 31 is fitted onto the bottom surface of the base 10, and the bottom surface of the lower plate 31 is flush with the surface of the base 10.

[0043] The surface of the lower plate 31 is provided with a rotating handle 34 for driving the lower plate 31 to rotate.

[0044] The upper plate 32 is mounted on the top surface of the base 10, and two alignment rollers 36 are fixedly mounted on it. The axis between the two alignment rollers 36 forms a 90° angle with the bearing between the positioning rollers 20. The relative positions change as the elastic rotary device rotates, thereby adjusting the lateral spacing between the two glass substrates.

[0045] The connecting rod assembly 33 passes through the base 10, and its two ends are respectively connected to the upper plate 32 and the lower plate 31, so that the upper plate 32 and the lower plate 31 rotate in linkage.

[0046] Specifically, the linkage assembly 33 includes a first connecting rod 331 and a second connecting rod 332.

[0047] The first connecting rod 331 is connected to the middle of the upper plate 32, and its end has an internal threaded hole.

[0048] The second connecting rod 332 is connected to the middle part of the lower plate 31, and its end has an external thread that mates with the internal threaded hole.

[0049] The total length of the connecting rod assembly 33 can be changed by rotating and adjusting the thread engagement depth between the second connecting rod 332 and the first connecting rod 331.

[0050] The bearing is installed in the area between the base 10 and the connecting rod assembly 33, specifically in the shaft hole between the base 10 and the first connecting rod 331, to reduce the rotational friction of the connecting rod assembly and improve the rotational flexibility of the elastic rotary device.

[0051] The reset mechanism includes a first column 37, a second column 38, and an elastic element 39. Specifically, the first column 37 is vertically disposed on the bottom surface of the base 10. The second column 38 is vertically disposed on the bottom surface of the lower plate 31. The elastic element 39 is a spring, with its two ends connected to the first column 37 and the second column 38 respectively, providing a restoring force through elastic deformation to pull the elastic rotary device 30 back to the starting position.

[0052] When the elastic rotary device 30 rotates under the driving action of the rotating handle 34, it drives the alignment roller 36 at its top to rotate synchronously, thereby changing the relative position between the alignment rollers 36, rotating from the longitudinal position to the lateral position, thereby changing the lateral distance between the glass substrates on both sides, realizing the adjustment of the distance between the glass substrates, and thus realizing the alignment adjustment.

[0053] Specifically, the glass substrate is located on both sides of the elastic rotating device 30, with its bottom edge abutting against the positioning roller.

[0054] The working principle of this utility model is as follows:

[0055] When the glass substrate approaches the alignment device, the rotating handle is triggered to rotate the lower plate 31. The lower plate 31 then rotates the upper plate 32, causing the two alignment rollers on the upper plate 32 to slowly rotate from a longitudinal position to a transverse position. This increases the distance between the glass substrates and provides buffered contact, effectively reducing contact stress and preventing the glass base from impacting the alignment rollers. This prevents damage or jamming of the alignment rollers and scratches or brittle damage to the glass substrate, thus extending the lifespan of the device.

[0056] This invention uses a rotating elastic rotary device to drive the alignment roller to gradually contact the glass substrate. Combined with a polyurethane elastic layer for buffering, it significantly reduces contact stress, reducing the scratch rate of the glass substrate from over 35% to below 5%.

[0057] The alignment roller and the positioning roller are at an angle of 30-90° to achieve precise and continuous adjustment of the lateral spacing of the glass substrate (accuracy ±0.1mm) and avoid jamming.

[0058] The polyurethane layer on the positioning roller provides stable anti-slip resistance, preventing longitudinal displacement during glass substrate alignment.

[0059] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
