[0037] All terms used in the present disclosure have the same meanings as those understood by those of ordinary skill in the art to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined as such herein.

[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0039] like Figure 1-7 As shown, an embodiment of the present disclosure provides a glass substrate conveyor with dynamically adjustable width, comprising: a conveying mechanism 1 for conveying a glass substrate 4; a base 2 for mounting the conveying mechanism 1, wherein a plurality of conveying mechanisms 1 are sequentially arranged on the base 2 relatively along a width direction perpendicular to the conveying direction of the glass substrate 4; and a width adjustment mechanism 3 for achieving the movement of two relatively arranged conveying mechanisms 1 closer to or farther away from each other; wherein a width adjustment mechanism 3 is connected to a conveying mechanism 1.

[0040] For ease of explanation, Figure 4As shown, the two conveying mechanisms 1 arranged opposite to each other in the width direction are respectively referred to as the left conveying mechanism 1a and the right conveying mechanism 1b; the width adjustment mechanism 3 drives the conveying mechanism 1 connected thereto to approach or move away from another conveying mechanism 1 arranged opposite to the conveying mechanism 1 according to the yaw value and plate width data of the glass substrate 4 provided by its upstream (or controller or host computer, etc.), thereby realizing one or more movements of the left conveying mechanism 1a and the right conveying mechanism 1b approaching, moving away, one approaching and one moving away, and (synchronous or asynchronous) same-direction movement, so as to realize the straightening of the glass substrate 4 conveyed by the upstream yaw and adjust its width conveying direction, so as to ensure alignment and alignment with the downstream equipment for conveying. For example, when the glass substrate 4 transported on the left conveying mechanism 1a and the right conveying mechanism 1b is swayed to the left, the right conveying mechanism 1b moves toward the side of the left conveying mechanism 1a under the drive of the width adjustment mechanism 3, thereby driving the glass substrate 4 to move to the left and transport it along the conveying direction; when the glass substrate 4 is not aligned with the downstream equipment and is swayed to the right, the left conveying mechanism 1a and the right conveying mechanism 1b move synchronously to the left, thereby synchronously driving the glass substrate 4 to move to the left, thereby achieving the adjustment of the width conveying direction of the glass substrate 4. It is worth noting that in actual applications, when the glass substrate 4 needs to adjust both the sway and the conveying width direction at the same time, the above requirements can be synchronously achieved by separately controlling the movement of the left conveying mechanism 1a and the right conveying mechanism 1b; of course, the sway and the conveying width direction can be adjusted in sequence, or the conveying width direction and the sway can be adjusted in sequence. I will not go into details here.

[0041] In some embodiments, the conveying mechanism 1 is a roller conveying mechanism. Figure 1-5 As shown, the roller conveying mechanism includes a conveying roller 11, a roller shaft 12, a support bearing 13, a support plate 14, a driving motor 15, a synchronization component 16 and a base 17; the conveying roller 11 is sleeved on the outer side of the roller shaft 12; the roller shaft 12 is rotatably mounted on the support plate 14 through the support bearing 13; the support plate 14 is mounted on the base 17; the driving motor 15 synchronously drives all the roller shafts 12 to rotate through the synchronization component 16, so that the conveying roller 11 can convey the glass substrate 4 along the conveying direction.

In order to improve the planarity of the supporting surfaces of all the conveying rollers 11 on different roller shafts 12 and ensure their effective contact with the glass substrate 4, it is avoided that the long roller shaft 121 suspended on the inner support plate 14 can be effectively supported, so that the conveying surface of the conveying roller 11 on the suspended section of the long roller shaft 12 is arranged flush with the conveying surfaces of other conveying rollers 11, thereby ensuring the effectiveness of the contact between the conveying roller 11 and the glass substrate 4. In practical applications, a plurality of long roller shafts 121 and a plurality of short roller shafts 122 are sequentially arranged adjacent to each other along the conveying direction of the glass substrate 4, so that a short roller shaft 122 is arranged between two adjacent long roller shafts 121, and a long roller shaft 121 is arranged between two adjacent short roller shafts 122.

The mounting seat 325 also includes a first dustproof plate 3255 and a second dustproof plate 3256 that are relatively arranged along the width direction, one end of the first dustproof plate 3255 is connected to the first mounting plate 3251, the other end of the first dustproof plate 3255 is connected to the second mounting plate 3253, one end of the second dustproof plate 3256 is connected to the first mounting plate 3251, and the other end of the second dustproof plate 3256 is connected to the second mounting plate 3253, so that the accommodating cavity 3254 is a cavity with only one opening toward the base 2 for facilitating the cooperation between the walking wheel 321 and the base 2, thereby preventing impurities from invading the accommodating cavity 3254 and blocking the connection, thereby ensuring the smoothness and stability of the walking wheel 321.

[0049] In some embodiments, the running wheel 321 is concavely matched with the base 2. Specifically, the middle part of the running wheel 321 is concave to form a groove 3211, and the corresponding base 2 is provided with or part of its structure forms a protrusion (such as the first substrate 21 and the second substrate 22) that matches the groove 3211.

[0050] In some embodiments, the running wheel 321 is a heat-treated steel running wheel. For example, the running wheel 321 is made of bearing steel GGr15 and is heat-treated to have a hardness of HRC55-60, high hardness and wear resistance.

Exemplarily, the limit distance of the right conveying mechanism 1b moving to the left is L, and when the right conveying mechanism 1b moves from the leftmost limit position to the right, its limit distance is also L.

Multiple conveyor belt conveying mechanisms are arranged at intervals along the width direction, and the width adjustment mechanism 3 adjusts the corresponding conveying mechanism 1 to be close to or away from the conveying mechanism 1 arranged adjacent to it, thereby adjusting the swing and conveying width of the glass substrate 4. The conveyor belt conveying mechanism includes a conveyor belt, a driving wheel, a driven wheel and a motor. The driving wheel and the driven wheel are arranged relatively along the conveying direction of the glass substrate 4.
