Description

Technical Field

[0001] This application belongs to the field of coating technology, and in particular relates to a coating fixture for double-sided coating of a substrate. Background Technology

[0002] With the development of modern industry, substrates are coated to give them various functions in industrial technology fields such as optics, architecture, aerospace, medical, and integrated circuits. For example, coatings are applied to optical component substrates and integrated circuit silicon wafer substrates to give them functions such as reflection, filtering, and conductivity. Vacuum coating is currently a widely used coating technology.

[0003] The coating process requires the use of coating fixtures to hold the substrate to be coated and place it into the coating machine for coating. With the development of the coating industry, higher requirements have been placed on the production efficiency and cost of coating. Double-sided coating equipment can coat both sides of the substrate simultaneously, thereby reducing costs and increasing efficiency. However, with current coating fixtures, after holding the substrate, the coating machine can only coat one side of the substrate at a time. After coating one side, the substrate must be flipped over before coating can continue. In addition, the coating fixture can only hold one substrate to be coated, resulting in low production efficiency and high production costs. Therefore, it is necessary to develop and design coating fixtures with new structures to meet the development needs of the coating industry for cost reduction and efficiency improvement.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Example 1

[0040] Embodiment 1 of this application provides a coating fixture for double-sided coating of a substrate. The coating fixture comprises a pair of fixture frames and an external threaded connector. The structure of the pair of fixture frames is as follows: Figure 1 As shown, a pair of clamping frames includes an identical upper clamping frame and a lower clamping frame, which are detachably connected. The upper clamping frame is provided with a set of two identical upper through square holes, and the lower clamping frame is provided with a corresponding set of two identical lower through square holes. The substrate is clamped in the upper and lower through square holes. In this embodiment, four identical lower internal threaded through holes are provided at two diagonal positions of the upper and lower clamping frames, and external threaded connectors are provided. The external thread of the external threaded connector matches the thread of the internal threaded through hole, so that the upper clamping frame and the lower clamping frame are detachably connected.

[0041] When using the coating fixture provided in this embodiment for coating processes, the substrate to be coated can be clamped in the upper through square hole and the lower through square hole. Since the coating fixture provided in this embodiment includes a set of identical upper through square holes and a corresponding set of identical lower through square holes, for example, including two upper through square holes and two corresponding lower through square holes, the coating fixture provided in this embodiment can clamp two substrates to be coated at the same time. When placed in a double-sided coating equipment, both sides of the substrate to be coated can be coated simultaneously, thereby improving the coating production efficiency and reducing the coating production cost. The coating fixture with the new structure provided in this embodiment can meet the development needs of the coating industry for cost reduction and efficiency improvement.

[0042] Example 2

[0043] Embodiment 2 of this application provides a coating fixture for double-sided coating of a substrate. The difference between the coating fixture and Embodiment 1 is that the coating fixture provided in this embodiment has an upper support part on the opposite side wall of the upper through square hole and a lower support part on the opposite side wall of the lower through square hole. Since the square hole, whether it is a square hole or a rectangular hole, includes four side walls and two pairs of opposite side walls, the coating fixture provided in this embodiment has a pair of upper support parts / upper support parts on the side wall in the length direction of the square hole.

[0044] When the coating fixture provided in this embodiment is used for coating process, in addition to coating substrates with the same size as the upper through square hole and the lower through square hole, it can also coat substrates with smaller widths. When a substrate with a width smaller than the width of the upper through square hole / lower through square hole is placed in the upper through square hole / lower through square hole, the upper / lower support portion prevents the substrate from falling off the upper through square hole / lower through square hole.

[0045] Example 3

[0046] Embodiment 3 of this application provides a coating fixture for double-sided coating of a substrate. The difference between the coating fixture and Embodiment 1 is that the coating fixture provided in this embodiment has an upper support portion on the opposite side wall of the upper through square hole and a lower support portion on the opposite side wall of the lower through square hole. Since the square hole, whether it is a square hole or a rectangular hole, includes four side walls and two pairs of opposite side walls, the coating fixture provided in this embodiment includes two pairs of upper support portions, that is, a pair of upper support portions is provided on the side wall in the length direction of the square hole and a pair of upper support portions is also provided on the side wall in the width direction of the square hole.

[0047] When the coating fixture provided in this embodiment is used for coating process, in addition to coating substrates with the same size as the upper through square hole and the lower through square hole, it can also coat substrates with smaller length or width. When a substrate to be coated with a width smaller than the width of the upper through square hole / lower through square hole is placed in the upper through square hole / lower through square hole, the upper / lower support portion prevents the substrate to be coated from falling off the upper through square hole / lower through square hole.

[0048] Example 4

[0049] Embodiment 4 of this application provides a coating fixture for double-sided coating of a substrate.

The external thread of the external threaded fastener, the internal thread of the upper through threaded through hole and the internal thread of the lower through threaded through hole match.

[0050] When using the coating fixture provided in this embodiment for coating processes, in addition to coating substrates with the same dimensions as the upper and lower through-holes, when encountering substrates with smaller lengths or widths, the clamping pieces can be embedded into the upper and lower through-holes. Then, the position of the clamping pieces inside the upper and lower through-holes can be adjusted by using the external threaded fastener, i.e., by screwing them inwards or outwards.

[0051] The substrate to be coated is pressed tightly inwards using clips to prevent it from falling off.

[0052] Example 5

The size of a single groove is 2*2*1mm.

[0054] When using the coating fixture provided in this embodiment for coating processes, in addition to coating substrates with the same dimensions as the upper and lower through square holes, when encountering substrates that are small in size but numerous, such as 18 substrates with dimensions of 2*2*2mm, seven identical clamping blocks can be embedded into the clamping plates inside the upper and lower through square holes, and three clamping plates can be embedded. Then, the 18 substrates with dimensions of 2*2*2mm are placed in the coating space formed by two opposing square grooves. This space is the position for clamping the substrates. Subsequently, the external threaded fastener is tightened inward, and the clamping plates are used to hold the substrates to be coated firmly, preventing them from falling off. The structure is as follows. Figure 4 As shown, this allows the coating fixture provided in this embodiment to simultaneously hold 18 substrates to be coated, and when placed in a double-sided coating equipment, both sides of the substrates to be coated can be coated simultaneously, thereby greatly improving the production efficiency of coating and reducing the production cost of coating.
