Description

Technical Field

[0001] This utility model relates to the technical field of adhesion testing equipment, specifically a photosensitive drum gear adhesion testing device. Background Technology

[0002] The bonding force between the drive gear and the conductive aluminum tube is a key control indicator for verifying the quality of the photosensitive drum. Currently, the bonding method between the drive gear and the conductive aluminum tube is mainly adhesive bonding. Therefore, the adhesion between the drive gear and the conductive aluminum tube is crucial, and thus, adhesion testing is required.

[0003] A search revealed a patent, CN221198744U, which discloses a photosensitive drum gear adhesion testing device. The device includes a base plate and a pulling mechanism. The pulling mechanism is located at one end of the upper part of the base plate. This device allows the photosensitive drum's drive gear to be placed inside the main clamping plate during adhesion testing of the drive gear and conductive aluminum tube. Then, by turning the main hand screws on both sides of the main clamping plate in conjunction with the threaded sleeves, the main clamping blocks are used to fix and hold the drive gear. This clamping action improves the stability of the drive gear. The conductive aluminum tube of the photosensitive drum is then fixed to the other end of the tensile testing instrument. Pulling the pull rod causes the adjusting block to slide and adjust to a suitable position on the slide groove in conjunction with the pulley. Finally, rotating the transmission plate and rotating shaft engages the limiting post into the limiting hole to fix and limit the adjusting block, thus improving the tensile stability of the main clamping plate.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative documents describe a manual pulling method for conducting tensile tests on photosensitive drums. This manual testing reduces efficiency and increases the workload for testers when testing a large number of photosensitive drums. Furthermore, the aforementioned comparative documents can only test the tensile force of photosensitive drums and cannot test their torque, thus reducing the testing scope for adhesive force tests. Therefore, there is an urgent need in the art to improve the photosensitive drum gear adhesive force testing device to overcome the shortcomings of the prior art. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-8A photosensitive drum gear adhesion testing device includes a support plate 1, a rotating platform 2 rotatably connected to one side of the support plate 1, a rotation drive unit for driving the rotating platform 2 to rotate on one side of the support plate 1, two symmetrical first sliding seats 3 slidably connected on the rotating platform 2, a first sliding groove 4 adapted to the first sliding seats 3 on the side of the rotating platform 2 away from the support plate 1, and clamping units for clamping both ends of the photosensitive drum assembly on both rotating platforms 2. Two upper fixing plates 5 and lower fixing plates 6 are located above and below the rotating platform 2 on one side of the support plate 1, and the upper and lower ends of the support plate 1 are respectively provided for driving the upper fixing plate 5 or the lower fixing plate 6 up and down. The movable up-and-down drive unit has an upper connecting member 7 on the upper fixed plate 5, a torque sensor 8 for testing torque is located between the upper connecting member 7 and the first sliding seat 3, and a lower connecting member 9 on the lower fixed plate 6, a tension sensor 10 for testing tensile force is located between the lower connecting member 9 and the first sliding seat 3. A main controller 11 is located on one side of the bearing plate 1. The main controller 11 is electrically connected to the torque sensor 8, the tension sensor 10, the rotary drive unit, the clamping unit, and the up-and-down drive unit. The clamping unit includes a clamping seat 12 fixedly installed on one side of the first sliding seat 3. Two symmetrical second sliding seats are located on the side of the clamping seat 12 away from the rotary table 2. The moving base 13 and the clamping base 12 have a second sliding groove 14 on one side that is adapted to the second sliding base 13. A first drive screw 16 that is threadedly connected to the two second sliding bases 13 is rotatably connected in the second sliding groove 14. A first drive motor 15 for driving the first drive screw 16 to rotate is fixedly installed on one side of the clamping base 12. A moving plate 17 is fixedly installed on one side of the second sliding base 13. The two moving plates 17 have clamping frames 18 on their facing sides that are adapted to the two ends of the photosensitive drum assembly. The rotation drive unit includes a second drive motor 21 fixedly installed on the side of the support plate 1 away from the rotating table 2. A through-plate is fixedly installed on one side of the rotating table 2. The rotating shaft 19 extends beyond one side of the support plate 1 and a first gear 20 is fixedly installed on its side. A second gear 22 that meshes with the first gear 20 is fixedly installed at the output end of the second drive motor 21. The upper and lower drive unit includes a third sliding seat 23 fixedly installed on the side of the upper fixed plate 5 or the lower fixed plate 6. Two third sliding grooves 24 adapted to the third sliding seat 23 are opened on one side of the support plate 1. A second drive screw 25 that is threadedly connected to the third sliding seat 23 is rotatably connected in the third sliding groove 24. A third drive motor 26 for driving the second drive screw 25 to rotate is fixedly installed at both the upper and lower ends of the support plate 1.

[0031] Specifically, when an adhesion test is required on the photosensitive drum assembly, the photosensitive drum assembly to be tested is placed between multiple upper and lower clamping frames 18, with the clamping frames 18 adapted to both ends of the photosensitive drum assembly. The main controller 11 starts two first drive motors 15, and the output of the first drive motors 15 drives the first drive screw 16 to rotate. The threads of the first drive screw 16 located on the inner side of the second sliding groove 14 are symmetrical and opposite. When the first drive screw 16 rotates, it drives two second sliding seats 13 to move towards each other within the second sliding groove 14. The second sliding seats 13 drive the moving plate. 17 moves, and the moving plate 17 drives the clamping frame 18 to move. Several clamping frames 18 clamp both ends of the photosensitive drum assembly. When a tensile test is required on the photosensitive drum assembly, the third drive motor 26 located below is turned on. The output end of the third drive motor 26 drives the second drive screw 25 to rotate. When the second drive screw 25 rotates, it drives the third sliding seat 23 to move down in the third sliding groove 24. The third sliding seat 23 drives the lower fixed plate 6 to move down, and a tensile test is performed on the photosensitive drum assembly. During the pulling process, the tensile sensor 10 transmits data to the display screen of the main controller 11. The curve is displayed until the tensile test of the photosensitive drum assembly is completed within a certain threshold. When the torque test of the photosensitive drum is required, the third drive motor 26 above the support plate 1 is turned on, driving the upper fixed plate 5 to move upward, so that the photosensitive drum is in a taut state. Then the second drive motor 21 is turned on. The output end of the second drive motor 21 drives the second gear 22 to rotate. The second gear 22 drives the first gear 20 to rotate. The first gear 20 drives the rotating shaft 19 to rotate. The rotating shaft 19 drives the rotating table 2 to rotate. At this time, the torque sensor 8 records the generated torque and outputs the data. The data is transmitted to the main controller 11, and the status is displayed via a curve. The first drive motor 15 drives the two clamping frames 18 to move towards each other to clamp and fix the end position of the photosensitive drum assembly, which facilitates the clamping and fixing of the photosensitive drum assembly. The third drive motor 26 drives the lower fixing plate 6 to move down, which, together with the tension sensor 10, facilitates the tension test of the photosensitive drum assembly. The second drive motor 21 drives the rotary table 2 to rotate, which, together with the torque sensor 8, enables the torque test of the photosensitive drum assembly, improving the efficiency and range of the adhesion test of the photosensitive drum assembly.

[0032] As a technical optimization of this utility model, the upper fixing plate 5 and the lower fixing plate 6 are each provided with two symmetrical clamping blocks 27 for clamping the upper connector 7 and the lower connector 9 respectively. The clamping blocks 27 can clamp the upper connector 7 and the lower connector 9 of different sizes. The upper fixing plate 5 and the lower fixing plate 6 are provided with adjustment grooves 28 that are adapted to the clamping blocks 27 through the side. The upper fixing plate 5 and the lower fixing plate 6 are each provided with an adjustment threaded rod 29 that is rotatably connected through the side. The adjustment threaded rod 29 is threaded to the clamping block 27. The outer end of the adjustment threaded rod 29 is threaded to a limit nut 30. The two clamping blocks 27 are provided with a suitable replaceable clamping ring 31 on the opposite side. The replaceable clamping ring 31 is provided with a limit ring 32 on one side. The clamping block 27 is provided with a limit groove 33 that is adapted to the limit ring 32 on one side.

[0033] Specifically, the position of the upper fixing plate 5 or the lower fixing plate 6 can be adjusted according to the length of the photosensitive drum assembly, or the upper connector 7 or the lower connector 9 can be replaced according to the threshold range during testing. The upper limit ring 32 of the replaceable clamping ring 31, which is adapted to the size of the upper connector 7 or the lower connector 9, is engaged in the position of the upper limit groove 33 of the clamping block 27. The limit ring 32 and the limit groove 33 can be an interference fit to ensure the stability of the replaceable clamping ring 31 and prevent it from easily detaching from the clamping block 27. By rotating the adjusting thread rod 29, the threads of the adjusting thread rod 29 on the inner side of the adjusting groove 28 are symmetrical and opposite. When the adjusting thread rod 29 rotates, it drives the two clamping blocks 27 to move towards each other. The two replaceable clamping rings 31 are clamped on the side of the upper connector 7 or the lower connector 9. Then the limit nut 30 is locked to improve the applicability of the photosensitive drum adhesion test.
