Description of the Invention (1.) The present invention relates to a method and device for cooling a substrate, especially an optical data carrier. When manufacturing optical data carriers, such as CDs, DVDs, DVRs and similar products, it may be necessary to cool the substrate that forms the data carrier or the data carrier itself between different manufacturing steps. In this way, the substrate can be moved, for example, through a cooling gas environment. However, this cooling method may cause uneven temperature distribution in the substrate, and thus cause stress, because local temperature differences in the atmosphere of the cooling gas are extremely difficult to avoid, and are generated by, for example, gas flowing out from one side of the substrate. In addition, this cooling method is relatively time-consuming. Therefore, the task of the present invention is to provide a method and an apparatus that can quickly and uniformly cool a substrate. According to the invention, this task is solved in a method of cooling a substrate, especially an optical data carrier, such that the substrate is rotated by an air flow. By rotating the substrate, the local temperature distribution in the environment around the substrate is uneven and can be balanced during cooling. In addition, the cooling process can be accelerated by turning. The substrate is rotated by the air flow, and a simple and low-cost substrate rotation driving method is also provided. According to a particularly preferred embodiment of the invention, the airflow is directed to the contoured peripheral surface of the substrate fixing device. By directing the air current to the peripheral surface of the contour, the kinetic energy of the air current can be smoothly transferred to the substrate fixing device, so the substrate is protected. The substrate is taken and turned to one of the substrate fixing devices. For good force conversion, the airflow is preferably offset sideways from a plane passing through the axis of rotation and guided to the peripheral surface of the substrate holding device. According to a preferred embodiment of the invention, the substrate fixing device moves through the cooling chamber together with the substrate to provide a controllable cooling environment and accelerate the cooling. The paper size is in accordance with China National Standard (CNS) A4 (21G X 297 mm). ^) ~~ '' ----- (Please read the notes on the back of the page before filling out this page) tr ·· -Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 584840 A7 V.

Note In order for the substrate to continue to move in a simple manner, the substrate holding device is preferably moved together with a conveyor belt. In order to make the substrate fixing device and the airflow have a certain direction, the movement of the conveyor belt is the most progressive, and the movement is temporarily suspended during this time. The airflow is preferably directed to the wheel gallery 'surface of the substrate fixture when the motion is paused. In order to use the airflow for cooling the substrate as well, it is preferred that at least a part of the airflow is guided through the contour peripheral surface of the substrate fixing device to the substrate. The meaning of the present invention is that it can also be solved by a cooling wire, especially an optical data device. Among them, a device that rotates the substrate with air current is provided. In such a device, the above-mentioned advantages can be obtained, that is, the rapid cooling of the substrate and the simple and low-cost rotation of the substrate. Line According to the real invention of the special service, this rehearsal device has a silkworm device on the periphery of the gallery, and a nozzle pointing at the scales. Precisely turning the substrate_device wheel turns the material, which can make the substrate fixing device rotate easily and cost-effectively.

In order to make the airflow have a good force to be transferred to the substrate manifold device, the plane of the nozzle and the plane passing through the axis of rotation is offset laterally, so it is directed. In order to allow multiple substrates to be cooled at the same time, it is best to set multiple substrates for fixed installation.

According to a preferred embodiment of the invention, the substrate fixing device has a centering pin with a centering portion, which can extend into the inner hole of the substrate and has a support surface under the centering portion. In this way, a simple and low-cost substrate fixing device is obtained, which does not have a controllable claw-hand element, but can securely hold the substrate during cooling. A fan blade profile is preferably formed on the peripheral surface of the substrate fixing device to effectively convert the impact force between the airflow and the substrate fixing device. In a preferred embodiment of the invention, the contour of the centering pin below the support surface is designed for the substrate. The peripheral surface of this contour should be printed at a distance from the support surface of the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, so that the airflow directed to the peripheral surface of the contour will not substantially affect the cooling of the substrate placed on the support surface. In another embodiment of the invention, the contour of the peripheral surface is designed in such a way that the airflow directed thereon can be directed in the direction of the substrate. According to an embodiment of the invention, the contour peripheral surface is offset radially outward from the bearing surface of the centering pin.
