Description

Technical Field

[0001] This application relates to the technical field of photoreceptor drum processing, and specifically, it is a device for detecting the film thickness of the surface substrate of a photoreceptor drum. Background Technique

[0002] Organic photoconductors are important materials widely used in industries such as laser printing and digital copying. A photoreceptor drum is an optoelectronic conversion device formed by coating a photosensitive material on the surface of a conductive aluminum tube. The thickness uniformity of the photosensitive material coated on its surface directly affects the product quality of the photoreceptor drum and the printing quality of the laser printing system. In the processing and production of photoreceptor drums, the surface substrate is generally coated by dip coating, and it is easy for external factors to cause uneven film thickness. After dip coating, it is necessary to detect the uniformity of the film thickness on the surface of the base tube to ensure the quality of the photoreceptor drum products.

[0003] Traditional detection methods use a thickness detector to obtain the film thickness value of the coating on the surface of the base tube, and judge the uniformity of the film thickness of the coating on the surface of the base tube by using the film thickness values at different points. When detecting the film thickness at different positions on the surface of the base tube, it is necessary to manually hold the base tube and move or rotate it to convert different positions, which is extremely inconvenient to use.

[0004] Therefore, this application provides a device for detecting the film thickness of the surface substrate of a photoreceptor drum to solve the above problems. Content of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] Embodiment 1

[0031] This embodiment provides a device for detecting the film thickness of the surface substrate of a photosensitive drum, as shown in Figure 1 , Figure 2 and Figure 3 . The detection device includes a controller 1, a base 2, two slide bases 3 slidably mounted on the base 2, a fixed cylinder 4 rotatably mounted on the slide bases 3 for inserting the end of the photosensitive drum, a thickness sensor 5 longitudinally moving above the two slide bases 3 on the base 2, and a driving mechanism 6 provided on the base 2 for driving the thickness sensor 5 to move. The thickness sensor 5 is connected to the input end of the controller 1; the fixed cylinder 4 includes a sleeve 41 rotatably mounted on the slide base 3. A positioning groove 411 for inserting the end of the base tube is provided at one end of the sleeve 41 away from the slide base 3, and a rubber ring 42 in contact with the outer wall of the end of the base tube is fixedly mounted on the inner wall of the positioning groove 411.

[0032] During use, one end of the base tube is placed in the positioning groove 411 of one of the sleeves 41, and then the other sliding seat 3 is moved so that the sliding seat 3 drives the other fixed cylinder 4 to move closer to the other end of the base tube, inserting the other end of the base tube into the sleeve of the fixed cylinder 4. Through the action of the rubber ring 42, the end of the base tube is fixed in the sleeve 41. Then, the thickness sensor 5 is driven by the driving mechanism 6 to move closer to the base tube so that the thickness sensor 5 can detect the film thickness at the corresponding position on the surface of the base tube. After the thickness sensor 5 detects the film thickness value at the corresponding position, the detected film thickness value is transmitted to the controller 1 for recording and used for subsequent uniformity judgment. When it is necessary to detect the film thickness at the axial position on the surface of the base tube, the sliding seat 3 is pushed so that the two sliding seats 3 drive the base tube to move horizontally on the base 1, changing the axial position of the base tube. When it is necessary to detect the film thickness at the axial position of the base tube, by rotating one of the fixed cylinders 4, the fixed cylinder 4 drives the base tube to rotate axially on the sliding seat 3, changing the circumferential position of the base tube.

[0033] Among them, in order to ensure the stability of the positioning of the base tube, a positioning post 43 for inserting into the base tube is provided at the inner center position of the positioning groove 411. In this way, after the end of the base tube is inserted into the positioning groove 411, the positioning post 43 in the positioning groove 411 is inserted into the interior of the base tube to support and position the base tube, making the base tube stable.

[0034] To facilitate the rotation of the base tube so that the thickness sensor 5 can detect the film thickness values at different circumferential positions on the outer wall of the base tube, as Figure 1 、 Figure 2 and Figure 3 shown, the fixed cylinder 4 further includes a support disk 44 provided at one end of the sleeve 41 close to the sliding seat 3 and rotatably connected to the sliding seat 3. The outer diameter of the support disk 44 is at least larger than the outer diameter of the sleeve 41, thus forming a part for the staff to hold, facilitating the staff to rotate the fixed cylinder 4 to axially rotate the base tube on the sliding seat 3 to change the circumferential position of the surface of the base tube.

[0035] To ensure the consistency of the movement of the two sliding seats 3, as Figure 1 、 Figure 2 and Figure 4 shown, a guide rail 21 is fixedly installed on the base 2, and the two sliding seats 3 are both slidably installed on the guide rail 21. Using a horizontal guide rail 21, the two sliding seats 3 are on a horizontal line. After the base tube is installed on the two sliding seats 3, pushing one of the sliding seats 3 can make the base tube move horizontally on the base 2, changing the axial position corresponding to the thickness sensor 5.

[0036] Among them, in order to ensure the stability of the structure of the sliding seat 3, guide grooves 22 are provided at both sides of the base 2 corresponding to the guide rails 21, and sliders 31 fixedly connected to the sliding seat 3 are slidably installed inside the guide grooves 22; the sliders 31 are slidably installed in the guide grooves 22, thereby restricting the sliding seat 3 on the base 2.

[0037] It should be noted that the guide grooves 22 are limiting sliding grooves closed at both ends. With the cooperation of the guide grooves 22 and the sliders 31, the sliding seat 3 can be effectively prevented from detaching from the base 2, thereby further improving the stability of the structure of the sliding seat 3.

[0038] Embodiment 2

[0039] This embodiment provides a device for detecting the film thickness of the surface substrate of a photosensitive drum. Different from Embodiment 1, as Figure 1 and Figure 2 shown, the driving mechanism 6 includes a support frame 61 fixedly arranged at one side of the base 2 corresponding to the two sliding seats 3, a movable plate 62 that moves closer to or away from the base 2 above the two sliding seats 3 on the support frame 61, and an adjusting screw rod 63 rotatably installed on the support frame 61 and passing through the movable plate 62, and the movable plate 62 is screwed to the adjusting screw rod 63; among them, the controller 1 is fixedly installed on the support frame 61, and the thickness sensor 5 is fixedly arranged on the movable plate 62.

[0040] After the base tube is installed, by rotating the adjusting screw rod 63, the adjusting screw rod 63 drives the movable plate 62 to move closer to the base 2, thereby driving the thickness sensor 5 to move closer to the base tube, so that the thickness sensor 5 can detect the film thickness value on the surface of the base tube.

[0041] Among them, in order to improve the stability of the movement of the movable plate 62, the driving mechanism 6 further includes a guide rod 64 fixedly arranged on the support frame 61 and longitudinally passing through the movable plate 62, and the guide rod 64 is arranged parallel to the adjusting screw rod 63; the movable plate 62 is restricted by the guide rod 64, so that the movable plate 62 longitudinally moves on the support frame 61 under the action of the adjusting screw rod 63, and the movable plate 62 is prevented from rotating with the adjusting screw rod 63 when the adjusting screw rod 63 rotates.

[0042] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
