DETAILED DESCRIPTION

[0032] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0033] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0034] like Figures 1 to 5 As shown, the utility model provides an optical fiber mounting seat 1 for mounting an optical fiber 300, wherein the optical fiber 300 can be a detection optical fiber for detecting the position of a substrate. The optical fiber mounting seat 1 includes a main body 11 and a pressing member 12, and can also include a first locking member 13 and a second locking member 14.

[0035] Reference Figure 2 and Figure 5 The main body 11 is provided with an installation space 111 and an inlet 112 and an outlet 113 communicating with the installation space 111. In addition, the main body 11 may also be provided with a locking hole 114 communicating with the outlet 113. One end of the inlet 112 passes through the main body 11 and communicates with the outside, and the other end extends to the installation space 111 and communicates with the installation space 111. One end of the outlet 113 passes through the main body 11 and communicates with the outside, and the other end extends to the installation space 111 and communicates with the installation space 111. The extension directions of the inlet 112 and the outlet 113 may be perpendicular to each other. For example, one end of the inlet 112 passes through the main body 11 in the horizontal direction, and one end of the outlet 113 passes through the main body 11 in the vertical direction.

[0036] The installation space 111 is used to accommodate the pressing member 12 and part of the optical fiber 300. The installation space 111 can extend to at least one surface of the main body 11 and communicate with the outside, so that the pressing member 12 can be installed from the outside into the installation space 111. In this embodiment, the installation space 111 can extend to three surfaces connected to the main body 11 and communicate with the outside, for example, the installation space 111 extends to two adjacent side surfaces of the main body 11 and the bottom surface of the main body 11.

[0037] Among them, refer to Figure 5 , the installation space 111 may specifically include a first groove 1111 and a second groove 1112 that are interconnected. The first groove 1111 may be formed by being recessed from the side wall and / or bottom wall of the main body 11, so that the first groove 1111 may extend to the side wall and / or bottom wall of the main body 11 and then communicate with the outside. Specifically, the first groove 1111 extends to three surfaces connected to the main body 11 respectively so that the first groove 1111 forms a groove with three openings. For example, the installation space 111 extends to two adjacent side surfaces of the main body 11 and the bottom surface of the main body 11 respectively. Among them, the first groove 1111 may be a square groove.

[0038] The second groove 1112 may be formed by being recessed from the sidewall forming the first groove 1111. Specifically, the sidewall forming the first groove 1111 includes a first sidewall 1113 parallel to the extending directions of the introduction port 112 and the outlet port 113, respectively, and the second groove 1112 is recessed from the first sidewall 1113. The depth of the recess of the second groove 1112 may be the same as the diameter of the optical fiber 300, for example, the depth of the recess of the second groove 1112 and the diameter of the optical fiber 300 are both 2 mm.

[0039] Reference Figure 2 One end of the locking hole 114 passes through the body 11 and communicates with the outside, and the other end communicates with the outlet 113 of the body 11. The extension direction of the locking hole 114 can be perpendicular to the extension direction of the outlet 113, for example, the locking hole 114 extends in the horizontal direction. The locking hole 114 can be used to accommodate the second locking member 14, so that the second locking member 14 can be installed in the locking hole 114 from the outside, and one end of the second locking member 14 can extend into the outlet 113 to fix the components installed in the outlet 113.

[0040] Reference Figure 2 , at least a portion of the pressing member 12 is received in the installation space 111 of the main body 11, and at least a portion of the pressing member 12 can abut against the optical fiber 300 located in the installation space 111, so as to press the optical fiber 300 against the main body 11, thereby achieving the fixation of the optical fiber 300. The pressing member 12 can press the optical fiber 300 into the second groove 1112. When the pressing member 12 presses the optical fiber 300, the end face of the pressing member 12 used to press the optical fiber 300 can be flush with the first side wall 1113 forming the first groove 1111, or slightly protrude from the first side wall 1113 and extend into the second groove 1112. By providing the second groove 1112 for receiving the optical fiber 300, the pressing member 12 can be convenient for pressing and fixing the optical fiber 300, and at the same time, it can also be prevented that the pressing force applied by the pressing member 12 to the optical fiber 300 is too large, thereby causing damage to the optical fiber 300. The pressing member 12 can be completely accommodated in the installation space 111 of the main body 11 , and the pressing member 12 is a pressing plate with a plate-like structure.

[0041] By using the clamping piece 12 to clamp and fix the optical fiber 300, it is possible to prevent the optical fiber 300 from swinging when following the movement of the optical fiber fixing device 100, thereby preventing the optical fiber 300 from being damaged by being clamped by the bottom of the optical fiber fixing device 100 due to the swing, thereby protecting the optical fiber 300 and preventing the optical fiber 300 from affecting the detection accuracy due to damage, thereby improving the detection accuracy of the optical fiber 300; in addition, by fixing the optical fiber 300 with the clamping piece 12, it is also possible to reduce the jitter of the optical fiber 300 during the movement, thereby improving the measurement accuracy of the optical fiber 300.

[0042] The first locking member 13 can be connected to the pressing member 12 and the main body 11 respectively, so as to apply a pressing force to the pressing member 12 toward the optical fiber 300, so that the pressing member 12 can compress and fix the optical fiber 300. Specifically, the first locking member 13 can pass through the pressing member 12 and the second groove 1112 and be fixedly connected to the main body 11, and the first locking member 13 abuts against the pressing member 12. By changing the connection depth between the first locking member 13 and the main body 11, the position of the pressing member 12 abutting against the first locking member 13 can be changed. When the connection depth between the first locking member 13 and the main body 11 increases, the first locking member 13 can drive the pressing member 12 to move toward the optical fiber 300 and press and fix the optical fiber 300; when the connection depth between the first locking member 13 and the main body 11 decreases, the first locking member 13 can be separated from the pressing member 12 and the pressing force applied to the pressing member 12 is released, and the position of the optical fiber 300 can be adjusted or the optical fiber 300 can be disassembled. Specifically, the first locking member 13 can be a screw, and the first locking member 13 is threadedly connected to the main body 11.

[0043] Reference Figures 2 to 4 The utility model also provides an optical fiber fixing device 100, which includes a lifting bracket 2 and the above-mentioned optical fiber mounting seat 1, and may also include an optical fiber protection tube 4, an optical fiber protection sleeve 5 and a connector 3.

[0044] Reference Figure 4 , the optical fiber mounting seat 1 is mounted on the lifting bracket 2 and can rise or fall relative to the lifting bracket 2. Specifically, the lifting bracket 2 can be provided with a lifting slot 21, and the optical fiber fixing device 100 is connected with a connector 3. At least a portion of the connector 3 is disposed in the lifting slot 21 of the lifting bracket 2, so that the connector 3 can move along the extension direction of the lifting slot 21; for example, the connector 3 includes a head and a rod head connected to each other, the head of the connector 3 abuts against the lifting bracket 2, the rod of the connector 3 penetrates into the lifting slot 21 and protrudes outward from the lifting slot 21 to connect with the optical fiber mounting seat 1, thereby connecting the optical fiber mounting seat 1 with the lifting bracket 2, and the optical fiber mounting seat 1 can move synchronously with the connector 3 along the extension direction of the lifting slot 21. Among them, the lifting slot 21 of the lifting bracket 2 can extend in the vertical direction, the connector 3 can be a screw, the head of the connector 3 is the head of the screw, and the rod of the connector 3 is the rod of the screw for forming an external thread. There may be two lifting slots 21 , and there may also be two connecting members 3 . Each connecting member 3 passes through one lifting slot 21 and is threadedly connected to the optical fiber fixing device 100 .

[0045] Reference Figure 3The optical fiber protection tube 4 is provided with an optical fiber protection channel connected to the lead-out port 113 of the optical fiber mounting seat 1, so that the optical fiber 300 can be led out from the lead-out port 113 of the optical fiber mounting seat 1 and then pass into the optical fiber protection tube 4, and extend in the optical fiber protection channel in the optical fiber protection tube 4, so that the optical fiber protection tube 4 can protect the optical fiber 300 accommodated in the optical fiber protection channel. Among them, at least a part of the optical fiber protection tube 4 can be arranged in the lead-out port 113 of the optical fiber mounting seat 1, for example, one end of the optical fiber protection tube 4 can extend into the lead-out port 113. When one end of the optical fiber protection tube 4 extends into the lead-out port 113, the second locking member 14 can be used to pass through the locking hole 114 and press the optical fiber protection tube 4 to fix the optical fiber protection tube 4, so that the optical fiber protection tube 4 can move synchronously with the optical fiber mounting seat 1.

[0046] The optical fiber protection sleeve 5 is provided with an optical fiber protection channel connected to the introduction port 112 of the optical fiber mounting seat 1. The optical fiber 300 can be inserted into the optical fiber protection sleeve 5 and extend from the optical fiber protection channel in the optical fiber protection sleeve 5 to the introduction port 112 of the optical fiber mounting seat 1. The optical fiber protection sleeve 5 is used to protect the optical fiber 300 accommodated in the optical fiber protection channel. Among them, one end of the optical fiber protection sleeve 5 can be fixedly mounted on the main body 11 of the optical fiber mounting seat 1, so that the optical fiber protection sleeve 5 can move synchronously with the optical fiber mounting seat 1. Specifically, one end of the optical fiber protection sleeve 5 extends into the introduction port 112 of the optical fiber mounting seat 1. The end of the optical fiber protection sleeve 5 extending to the introduction port 112 can be directly connected to the optical fiber mounting seat 1. For example, the end of the optical fiber protection sleeve 5 extending into the introduction port 112 can be interference fit with the introduction port 112 so that the optical fiber protection sleeve 5 is fixed to the optical fiber mounting seat 1, or the end of the optical fiber protection sleeve 5 extending to the introduction port 112 can be fixed to the main body 11 by means of clamping, bonding, etc. In addition, the end of the optical fiber protection sleeve 5 extending to the introduction port 112 can also be connected to the optical fiber mounting seat 1 through a threaded joint. For example, the end of the optical fiber protection sleeve 5 extending to the introduction port 112 is fixedly connected to the threaded joint by means of interference fit, bonding, clamping, etc., and the threaded joint is threadedly matched with the introduction port 112 of the optical fiber mounting seat 1, so that the end of the optical fiber protection sleeve 5 extending to the introduction port 112 can also be connected to the optical fiber mounting seat 1 through a threaded joint.

[0047] When the optical fiber 300 needs to be installed in the optical fiber fixing device 100, the optical fiber 300 can pass through the optical fiber protection sleeve 5, the introduction port 112 of the optical fiber mounting seat 1, the installation space 111 of the optical fiber mounting seat 1, the outlet 113 of the optical fiber mounting seat 1, and the optical fiber protection tube 4 in sequence. The end of the optical fiber 300 extending to the optical fiber protection tube 4 can be flush with the optical fiber protection tube 4 or protrude from the optical fiber protection tube 4, so as to facilitate the detection of the optical fiber 300; when the optical fiber 300 is installed in the optical fiber fixing device 100, the connection depth between the first locking member 13 and the main body 11 is shallow, and the pressing member 12 does not press the optical fiber 300 at this time, so as to facilitate the installation of the optical fiber 300. After the installation of the optical fiber 300 is completed, the first locking member 13 can apply a locking force to the pressing member 12, so that the pressing member 12 presses and fixes the optical fiber 300.

[0048] Reference Figure 1 The utility model also provides a coating device, including a storage table 200, an optical fiber 300 and the above-mentioned optical fiber fixing device 100.

[0049] The upper end surface 201 of the placement table 200 is used to place the substrate to be coated, and the placement table can be provided with a through hole so that other components can pass through the placement table 200 through the through hole of the placement table 200. For example, the optical fiber protection tube 4 in the optical fiber fixing device 100 can pass through the through hole of the placement table 200 and protrude from the upper end surface 201 of the placement table 200. At this time, the optical fiber 300 flush with the optical fiber protection tube 4 or protruding from the optical fiber protection tube 4 also protrudes from the upper end surface 201 of the placement table 200 and can detect the position of the substrate located on the upper end surface 201 of the placement table 200. Among them, the placement table 200 can be specifically a marble tabletop.

[0050] When the coating device is working, as different substrates are placed on the storage table 200, the optical fiber 300 needs to be repeatedly raised and lowered. Therefore, the optical fiber mounting seat 1 will be repeatedly raised and lowered relative to the lifting bracket 2, and the optical fiber 300 and the optical fiber protection tube 4 and the optical fiber protection sleeve 5 fixedly connected to the optical fiber mounting seat 1 will rise and fall synchronously with the optical fiber mounting seat 1, thereby preventing the optical fiber 300 installed in the optical fiber fixing device 100 from swinging during the lifting process.

Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model.
