Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing instruments, and in particular to a coating quality testing instrument. Background Technology
[0002] A coating quality inspection instrument is a professional testing device used to evaluate the performance of coated products. It is mainly used to measure and analyze key quality indicators such as coating thickness, uniformity, optical properties, and mechanical properties. These instruments play an important role in the field of precision manufacturing, especially in industries such as optical components, semiconductor devices, display panels, and decorative coatings.
[0003] When inspecting coated glass components, it is necessary to perform light transmittance testing on the blank base (uncoated glass material), followed by testing of the coated glass material and comparison of the two. This allows for the inspection of coated glass and an understanding of its quality. However, the testing process requires placing the coated glass inside a testing wall, and the coating quality testing instrument is also adapted for solution transmittance testing. Therefore, the following problems exist: 1. The internal testing chamber of the coating quality testing instrument is small, making component access inconvenient and time-consuming; 2. The testing chamber is easily contaminated, and debris from impacts is difficult to clean; 3. Prolonged operation of the testing chamber during testing increases the likelihood of contamination. Therefore, those skilled in the art have provided an oyster peptide processing and separation device to solve the problems mentioned in the background art. Utility Model Content
[0004] 1. Technical Solution
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a coating quality testing instrument, including a spectrophotometer, a testing box, a first side plate, a middle plate, a second side plate, a toothed plate, and a support bar. The testing box is located at the lower end of the spectrophotometer. Both ends of the testing box have travel openings, through which the support bar is installed. The second side plate, the middle plate, and the middle section of the support bar are respectively located at both ends. Two sets of symmetrically distributed placement seats are located above the support bar. Placement slots are provided inside the placement seats. A toothed plate is located on one side of the lower end of the side plate. A motor is located below the testing box, and a gear that meshes with the toothed plate is located at the output end of the motor.
[0007] Furthermore, the placement seats are distributed between side plate one and the middle plate, and between the middle plate and side plate two;
[0008] Specifically, the glass-based coated parts storage structure formed by the placement base is distributed in two groups, located in the testing box or outside.
[0009] Furthermore, the upper end of the support bar is provided with a guide rail, the lower end of the placement seat is provided with a sliding groove that is slidably installed with the guide rail, the placement seat is provided with a screw hole, and a screw with relatively distributed outer wall threads is threadedly inserted into the screw hole;
[0010] Specifically, the placement seat slides on the outer wall of the guide rail via a sliding groove. The threaded engagement between the screw and the screw hole, as well as the relatively distributed threads on the outer wall of the screw, enable the placement seat to move relative to or away from each other, thereby adjusting the size of the internal storage space of the placement seat.
[0011] Furthermore, the inner diameter of the placement groove is not uniform, a torsion block is provided at one end of the screw, and two sets of symmetrically distributed bearing brackets are provided at the upper end of the support bar, and the screw is rotatably installed inside the bearing brackets;
[0012] Specifically, the gripping torsion block facilitates the application of rotational force to the screw, which is supported by the bearing bracket. The slots with different inner diameters can be used to place glass-based coated parts of different thicknesses.
[0013] Furthermore, the lower end of the detection box is provided with a base plate, and equidistantly distributed ball bearings are rotatably installed inside the lower end of the base plate. The upper end of the toothed plate is provided with a guide groove, and the ball bearings are rotatably installed inside the guide groove.
[0014] Specifically, the ball bearings slide inside the guide groove to provide sliding support for the toothed plate, which improves the stability of the toothed plate when it moves, thereby improving the stability of the support bar.
[0015] Furthermore, the outer wall of the detection box is fitted with a side frame located outside the travel port, the support bar is located inside the side frame, the motor is fixed to the lower inner wall of the side frame, and operation ports are provided on both sides of the upper end of the side frame.
[0016] Specifically, the side frame shields the driving and moving structural components such as motors, gear plates, and support bars, and allows the storage and retrieval of glass-based coated parts through the operating port to the placement seat located outside the slot frame.
[0017] 2. Beneficial effects
[0018] Compared with existing technologies, the advantages of this utility model are:
[0019] This invention places the glass-based coated parts in the corresponding placement slot inside the placement seat. The light transmittance is detected by the light-emitting element and light source receiving structure inside the detection chamber, thereby understanding the quality of the glass-based coated parts. The placement seat for placing the glass-based coated parts is located on the connecting block and is distributed in two sets. One set is used for detection, and the other set is located outside the equipment for pre-storage. When the glass-based coated parts are detected, the placement seat located outside the equipment pre-stores the undetected glass-based coated parts, realizing the rapid storage and retrieval of the glass-based coated parts.
[0020] Meanwhile, the top of the testing chamber is closed, and the glass-based coated parts enter and exit the testing chamber through the travel port, avoiding the testing chamber from being open for a long time and reducing the possibility of contamination.
[0021] Meanwhile, the glass-based coated parts are stored and retrieved on the outside of the spectrophotometer detection box to avoid debris caused by bumps and damage during storage and retrieval being trapped inside the cavity and difficult to clean.
[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0035] Example 1
[0036] Please see Figure 1-5 As shown, this embodiment is a coating quality inspection instrument, including a spectrophotometer 1, an inspection box 2, a first side plate 5, a middle plate 6, a second side plate 7, a toothed plate 10, and a support bar 18. The inspection box 2 is set at the lower end of the spectrophotometer 1. Both ends of the inspection box 2 have stroke ports 8. The support bar 18 is installed through the stroke ports 8. The first side plate 5, the second side plate 7, and the middle plate 6 are respectively set at both ends and the middle section of the support bar 18. Two sets of symmetrically distributed placement seats 19 are set above the support bar 18. Placement slots 14 are opened inside the placement seats 19. The toothed plate 10 is set on one side of the lower end of the first side plate 5. The motor 9 is set below the inspection box 2. The output end of the motor 9 is set with a gear 13 that meshes with the toothed plate 10.
[0037] The placement seat 19 is located between side plate 1 5 and middle plate 6, and between middle plate 6 and side plate 2 7;
[0038] The upper end of the support bar 18 is provided with a guide rail 20, and the lower end of the placement seat 19 is provided with a sliding groove 23 that is slidably installed with the guide rail 20. The placement seat 19 is provided with a screw hole 12 inside, and a screw 22 with relatively distributed outer wall threads is inserted into the screw hole 12.
[0039] The inner diameter of the placement groove 14 is different. One end of the screw 22 is provided with a torsion block 11. The upper end of the support bar 18 is provided with two sets of symmetrically distributed bearing brackets 21. The screw 22 is rotatably installed inside the bearing bracket 21.
[0040] The bottom of the test box 2 is provided with a base plate 15, and the bottom of the base plate 15 is rotatably installed with equally spaced balls 16. The toothed plate 10 is provided with a guide groove 17 at the top, and the balls 16 are rotatably installed inside the guide groove 17.
[0041] The outer wall of the test box 2 is fitted with a side frame 3 located outside the stroke port 8, the support bar 18 is located inside the side frame 3, the motor 9 is fixed on the lower inner wall of the side frame 3, and the side frame 3 is provided with operation ports 4 on both sides of the upper end.
[0042] In this embodiment, during operation, the coated glass substrate to be tested and the blank glass substrate are first placed inside two sets of symmetrically distributed placement seats 19. By rotating the torsion block 11 at the front end of the screw 22, the relative movement of the screw thread is used to push the placement seat 19 to slide along the guide rail 20. The spacing of the placement slots 14 is adjusted according to the width of the glass substrate to ensure that the sample is stably fixed. After starting the motor 9, the gear 13 meshes with the toothed plate 10 to drive the support bar 18 to move laterally, so that one set of placement seats 19 enters the cavity of the detection box 2 through the stroke port 8, while the other set stays outside the side frame 3 for pre-loading the sample. During this process, the middle plate 6 always closes one stroke port 8, and the side plate 1 5 and the side plate 2 7 close the other stroke port 8.
[0043] The spectrophotometer 1 inside the detection box 2 is then activated. The light source component emits a specific wavelength beam that penetrates the glass substrate. The receiving end automatically calculates parameters such as film uniformity and thickness by comparing the transmittance difference between the coated part and the blank part. After the detection is completed, the motor 9 reverses to drive the support bar 18 to reset, completing the rapid switching of samples. A new set of samples then enters the detection position to achieve continuous operation.
[0044] Through the linkage design of the support bar 18 and the side plate, the two sets of placement seats 19 form a "testing and pre-loading" cycle mode. When one set of samples is tested, the other set can be loaded and unloaded from the outside, reducing the exposure time of the test chamber and significantly reducing the risk of dust pollution. The combination of bidirectional threaded screw 22 and guide rail 20 is adopted, and the spacing of placement seats 19 can be adjusted by rotating the torsion block 11. With the placement groove 14 with different inner diameters, it can be compatible with glass substrates of various specifications and thicknesses. The clamping force is kept constant by the thread self-locking.
[0045] The side frame 3 and the travel port 8 form a directional movement path. The support bar 18 slides smoothly under the precise guidance of the ball bearing 16 and guide groove 17, ensuring that the detection chamber only opens briefly and partially when the sample enters or exits. Together with the operation port 4 on the top of the side frame 3, a relatively quasi-closed working environment is achieved. The inner wall of the side frame 3 is treated with a nano-coating to reduce surface roughness and debris adhesion. The dual-station design reduces the time required to open and close the detection chamber. Combined with the physical isolation of the side frame 3, the equipment is given a certain degree of physical protection. The motor 9 drives the device instead of manual pushing and pulling, avoiding scratches on the substrate. The shielding design of the side frame 3 reduces the risk of contact with mechanical parts.
[0046] Upgrading the single-function modules of traditional testing equipment not only solves the problem of contamination control in coating testing, but also enables high-throughput continuous operation, providing an efficient and reliable quality inspection solution for the precision coating industry.
