Description

Transmission device

The disclosure relates to a transmission device.

When the thickness of the glass is reduced to a certain extent, it can be bent to form a flexible glass, which has the characteristics of bendability and high hardness, and can be applied to a flat substrate of an e-Paper, a protective cover in a photovoltaic module. , contact sensors, solid state light emitting devices and electronic devices. The material of the flexible substrate can be glass, polymer or metal.

Currently, thin glass can be conveyed in a roll-to-roll manner. Although flexible glass has a considerable degree of flexibility at ultra-thin thickness, it still retains the brittle nature of the material. The strength of the flexible glass may be concentrated due to surface defects or scratches. Drop 2 to 4 times. Any unstable transport force or drag and torsion of the flexible glass can cause cracking of the thin glass. There are two important issues that must be faced when transporting flexible glass through a roll-to-roll process to reduce the chance of rupture of the flexible glass during transport. One is the problem that the flexible glass is excessively stressed during the transmission process, including excessive tension and transmission offset, and the other is that the upper and lower surfaces of the flexible glass are subjected to the reverse forward and reverse directions.

The offset of the flexible substrate during the transfer process causes wavy winding, substrate ridges or side irregularities, and even wrinkles or cracks when the flexible substrate is wound. In addition, for high-precision soft electronic products, because the flexible substrate is shifted during transmission, the precision conditions that can be provided in the process are affected. To the limit, the demand for high precision cannot be met.

In addition, since the flexible winding line of the general winding production line must be transported and steered through a plurality of transfer wheels during the conveying process, it is usually interposed between the transfer wheels, so that the upper and lower surfaces of the flexible substrate and the transfer wheels are mutually Contact, and the upper surface of the flexible substrate is subjected to positive and negative forces, which may cause wrinkles and even cracks of the flexible substrate.

The present disclosure provides a transmission device that can prevent the object from being subjected to forward and reverse forces on the upper and lower surfaces during the process of transmitting the object, and provides the function that the process surface does not contact the roller, and can provide the transmission path of the object.

The present disclosure proposes a transmission device adapted to transmit an item along a transmission path. The transmission device comprises a control module, a unwinding module, at least one force sensing module and a winding module. The unwinding module includes a first actuating unit, and the first actuating unit is electrically connected to the control module. The object is adapted to be wound around the unwinding module and released by actuation of the first actuating unit. The tension sensing module is disposed on the transmission path, and each tension sensing module includes a transmission wheel set and a load element. The load cell is disposed on the transmission wheel set and electrically connected to the control module, and the object is transported along the transmission wheel set at a covering angle of less than 180 degrees. The winding module includes a second actuation unit, and the second actuation unit is electrically connected to the control module. The object is adapted to be wound into the winding module by actuation of the second actuating unit.

Based on the above, the transmission device of the present disclosure controls the transmission tension between the winding module and the unwinding module by controlling the rotation speed of the first actuation unit and the second actuation unit by the control module, and transmits the transmission wheel through the transmission wheel. Group formation The angle is called the covering angle. The load element can sense the tension value of the object under the covering angle and feed back to the control module, so that the control module controls the tension of the object within a specific range, so that the object is stably transmission. In addition, the transmission module of the present disclosure senses the offset condition of the object by the offset guiding module and drives the reverse movement of the unwinding module or the winding module in the offset direction to reduce the offset of the object. In addition, the object contacts the first transmission wheel set and the second transmission wheel set at a specific covering angle to reduce the probability of the object being subjected to the alternating force of the forward and reverse directions during the transmission, and the process can be broken. The surface does not touch the roller to prevent the process from failing.

The thin glass 10 is affected by factors such as parallelism between the first transfer wheel 132 and the second transfer wheel 162, uniformity of tension, or deformation of the thin glass 10 in the winding process apparatus, and the thin glass 10 is easily transported. A lateral offset or a left and right swing occurs. Therefore, in the vicinity of the unwinding module 120, the process area B, and the winding module 150, the position of the thin glass 10 must be corrected in time by the first offset guiding module 140 and the second bias guiding module 170.

In order to alleviate the above situation, in the present embodiment, each of the first transfer wheel 132 and each of the second transfer wheels 162 has a diameter greater than 3 turns so that the thin glass 10 is bent to a smaller extent.

Since the texture of the thin glass 10 is harder than that of the plastic substrate, if the thin glass 10 occurs during the transfer, the foreign matter runs between the thin glass 10 and the first transfer wheel 132 or the second transfer wheel 162, or because of the thin glass 10 and the first A slip is generated between a transfer wheel 132 or the second transfer wheel 162, which will be in the thin glass 10 The surface is scratched.

The control module 110 can adjust the rotation speed of the first actuation unit 122 to change the tension of the thin glass 10, and can control the third actuation unit 144 to move the first movement platform 124 laterally to achieve the guiding effect. The thin glass 10 is then fed into the process zone B for printing, laser or lamination. After the thin glass 10 leaves the process area B, the second position sensing unit 172 senses the edge position of the thin glass 10 to ensure the position of the thin glass 10 is correct. If the offset control module 110 is generated, the fourth actuation unit can be controlled. 174 moves the second mobile platform 194 sideways to guide. Then, the thin glass 10 passes through the second transfer wheel 162, and the second load cell 164 senses the tension value before the thin glass 10 is wound and transmits it to the control module 110, and the control module 110 adjusts the rotation speed of the second actuation unit 152.
