Description

Technical Field

[0001] This application relates to the field of coating apparatus, and more specifically to a lower fixing component used in a vacuum coating process in a vertical coating line. Background Technology

[0002] In the double-sided vacuum coating process, the front and back sides of the product need to be coated sequentially or simultaneously.

[0003] In a horizontal continuous coating production line, one side is usually coated at a time, and the product clamping mechanism is relatively simple. However, when coating the other side, a large number of mechanical equipment are required to assist, which increases the usage time, reduces the work quality, and makes the product more susceptible to damage.

[0004] Unlike horizontal continuous coating single-sided production processes, vertical coating lines have more complex product clamping. As workpiece sizes increase, the size of the coating chamber cathode also increases. Existing fixing mechanisms often suffer from problems such as unstable clamping leading to coating shift, obscuring the coating area and affecting film integrity, or insufficient positioning accuracy during face changing causing misalignment of the two film layers. These issues seriously affect product coating quality and production efficiency. There is an urgent need for a stable, reliable, and precisely positioned fixing mechanism to solve these problems.

[0012] As described above, a lower fixing assembly for vertical coating clamping has a connecting member on the lower fixing seat. The connecting member passes through the lower fixing seat, enters the guide groove, and is threadedly connected to the sliding member.

[0013] As described above, a lower fixing assembly for vertical coating clamping has an inwardly recessed bottom groove at the upper end of the lower clamping block, which is used to nest the bottom edge of the product to be processed to limit its movement.

[0014] As described above, in a lower fixing assembly for vertical coating clamping, the anti-slip component is a rubber ring, and the upper side of the lower clamping block is provided with an inwardly recessed annular groove for accommodating the rubber ring.

[0020] This application provides a simple clamping device for holding products on a vertical coating line during double-sided coating processes. The device includes a clamping frame, a lower fixing component on the lower side of the clamping frame to support the lower edge of the product to be processed, a side stop component on the side of the clamping frame to press the side of the product to be processed, and an upper clamping component on the upper side of the clamping frame to press the product to be processed downwards. This application achieves stable, reliable, and precise vertical clamping of products on a vertical coating line, preventing product tilting. It meets the requirements for vertical clamping of products during double-sided coating processes. The simple structure and convenient operation allow for quick and easy loading and unloading of products. Compared to horizontal lines, it increases work efficiency, reduces the risk of product collisions, and improves product coating quality and production efficiency.

The upper pressing member 23 is used to drive the upper clamping member 22 to press down on the product 5 to be processed. The upper clamping member can extend and retract on the upper fixing member. After pressing the upper edge of the product, it is locked and fixed by the upper pressing member. The operation is simple and can fix the upper edge of the product. It can realize stable, reliable and accurate vertical clamping of the product on the vertical coating line, prevent the product from tilting and moving during the coating process, and meet the needs of vertical clamping of the product in the double-sided coating process.

[0022] Furthermore, a vertical guide structure 24 is provided between the upper fixing member 21 and the upper clamping member 22.
