Description

Technical Field

[0001] This utility model relates to the field of roller manufacturing technology, and in particular to a roller inspection device. Background Technology

[0002] In the field of roller manufacturing technology, it is necessary to test the basic structural accuracy of the rollers to meet the precision requirements of the prepared lithium battery separators. This typically involves testing the rollers' roundness, roughness, cylindricity, and dynamic balance. For measuring roller roundness, a common method is to use a center stand and a dial indicator, with the dial indicator moving around the roller surface. However, this method is manual, prone to errors, and cannot obtain reliable overall roundness data, lacking sufficient reference value. In automated production operations, this can easily lead to oversights and ultimately production defects. Summary of the Invention

[0003] The purpose of this invention is to provide a roller inspection device for the inspection of rollers after processing. It can accurately record the deviation value of the roller arc surface position without manual recording, which helps to ensure the inspection accuracy and ensure that the prepared rollers meet the relevant accuracy requirements.

[0004] To achieve this objective, the present invention adopts the following technical solution: A roller inspection device includes a support frame and a first driving device. The support frame includes two opposing vertical plates, each with a placement groove on its upper surface. A bearing seat is placed in the placement groove, and the two bearing seats are used to support the roller to be inspected. The two vertical plates are also provided with fixing devices for fixing the bearing seats. The first driving device is used to drive the roller to be inspected, which is limited by the bearing seats, to rotate. A connecting frame is also installed between the two vertical plates. A grating ruler is installed on the connecting frame, and a contact block is provided at the reading head position of the grating ruler. The contact block can contact the surface of the roller to be inspected.

[0005] Furthermore, each of the two upright plates is provided with a sliding groove, and one end of the sliding groove is provided with a movable groove; the connecting frame is a sliding plate that is slidably disposed in the two sliding grooves, and a slide rail parallel to the sliding groove is installed on the upright plate, and a slider is slidably disposed on the slide rail, and the ends of the slider and the sliding plate are fixedly connected.

[0006] Furthermore, one end of the slide plate is provided with a flap that can move within the movable slot space; the upright plate is provided with a sliding guide rod that passes through the flap, and a spring is sleeved on the outside of the sliding guide rod, with the two ends of the spring respectively abutting against the flap and the inner side of the movable slot.

[0007] Furthermore, the grating ruler is configured in at least two sets and is fixedly mounted on the moving block, and each moving block is slidably mounted on the sliding plate.

[0008] Furthermore, an auxiliary roller is rotatably arranged between the two upright plates. The auxiliary roller is parallel to and close to the roller to be tested. Both the auxiliary roller and the roller to be tested are provided with gear sets that can mesh with each other. The first driving device is used to drive one gear in the gear set to rotate.

[0009] Furthermore, it also includes a transfer plate connected to the support frame, the transfer plate being provided with two sets of parallel transmission belts, and the transfer plate being provided with a second drive device for driving the two transmission belts to move synchronously.

[0010] Furthermore, the fixing device includes a detachable connecting block disposed above the placement groove, the connecting block being equipped with a threaded locking mechanism, the movable end of the threaded locking mechanism being able to abut against the bearing seat located within the placement groove.

[0011] The beneficial effects of this utility model are as follows: By utilizing the reading head of the grating ruler to contact the surface of the roller to be tested, this utility model can detect subtle changes in the curvature during the automatic rotation of the roller through contact with the reading head.

Detailed Implementation

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1 to 5 As shown, the present invention provides a roller inspection device for inspection work after roller processing. It can accurately record the deviation value of the roller arc surface position without manual recording, which helps to ensure the inspection accuracy and ensure that the prepared roller meets the relevant accuracy requirements.

[0017] Specifically, the roller inspection device includes a support frame and a first drive device 3. The support frame includes two opposing vertical plates 1, such as... Figure 1 and Figure 2 As shown, both vertical plates 1 have placement grooves on their upper surfaces, and bearing seats are placed in the placement grooves. These two bearing seats are used to support the roller to be tested and provide a base for the roller to rotate. The placement groove structure allows for quick placement and removal of the roller to be tested, which facilitates testing and replacement by personnel.

[0018] To maintain stability during testing, fixing devices for securing the bearing seats are installed on the two upright plates 1. Furthermore, to accurately detect the roundness deviation of the roller surface, a first drive device 3 is configured to drive the roller under test, which is limited by the bearing seats, to rotate. Figure 2 As shown, the fixing device includes a detachable connecting block 4 disposed above the placement groove. A threaded locking mechanism 5 is mounted on the connecting block 4, and the movable end of the threaded locking mechanism 5 abuts against a bearing seat located within the placement groove. The structure of the first driving device 3 is existing technology; for example, it can employ a motor to drive a gear to rotate, thereby rotating the roller to be tested.

[0019] like Figure 3 As shown, a connecting frame 6 is installed between the two upright plates 1. A grating ruler 7 is mounted on the connecting frame 6, and a contact block 8 is connected to the reading head of the grating ruler 7 so that the contact block 8 can contact the surface of the roller to be tested. With this configuration, during testing, the contact block 8 is manually placed against the surface of the roller to be tested. Driven by the first driving device 3, the roller to be tested rotates automatically, causing the contact block 8 to shift at the protruding position. The grating ruler 7 structure is then used to accurately measure the shift. It should be noted that if the initial position of the contact block 8 is precisely the protruding position of the roller to be tested, several concave positions need to be tested to obtain multiple sets of data for accurate determination of the measurement structure. The structure of the contact block 8 can be referenced... Figure 3 As shown, one side of the contact block is an arc surface for contacting the roller to be tested, thus enabling accurate pickup of the offset. For rollers of different diameters, contact blocks of different specifications can also be used for contact.

[0020] This utility model provides a roller detection device. To facilitate the adjustment of the installation position of the grating ruler 7 and thus the optimal distance between it and the roller to be detected, sliding grooves can be provided on both vertical plates 1, and a connecting frame 6 is configured as a sliding plate slidably disposed between the two sliding grooves. To stabilize the direction of the sliding plate, a slide rail 9 parallel to the sliding grooves can be installed on the vertical plate 1, such as... Figure 5 As shown, a slider 10 is slidably mounted on the slide rail 9, and the slider 10 is fixedly connected to the end of the slide plate. In this way, when it is necessary to adjust the distance between the grating ruler 7 and the roller to be inspected, the slider 10 is directly driven to translate relative to the slide rail 9, and then fixed after sliding into place. The fixing method of the slider 10 is not limited here; bolt locking or other methods can be used.

[0021] This utility model provides a roller detection device. To avoid the inability to find a suitable concave point after multiple measurements and to facilitate the judgment of the overall curvature change of the arc, a movable groove can be set at one end of the sliding groove, and a flap 11 that can move within the movable groove space is set at one end of the sliding plate. Figure 5 As shown. Specifically, the upright plate 1 is provided with a sliding guide rod 12 that passes through the flip plate 11, and a spring 13 is sleeved on the outside of the sliding guide rod 12. The two ends of the spring 13 respectively abut against the flip plate 11 and the inner side of the movable groove. With this structure, when the curvature of the roller to be tested changes, the contact block 8 can always be in close contact with the surface of the roller to be tested, thereby achieving linear measurement during rotation, which is more conducive to analyzing whether the overall roundness meets the requirements.

[0022] This utility model provides a roller detection device. To facilitate measurement of different positions in the radial direction of the roller to be detected, at least two sets of grating rulers 7 can be configured and fixedly mounted on the moving block, as shown below. Figure 3 As shown, each moving block is slidably mounted on the slide plate. In this embodiment, by configuring no fewer than two sets of grating rulers 7, the roundness of both ends of the roller under test can be directly measured, thus facilitating the analysis of the overall cylindricity. Since the moving blocks are slidably mounted on the slide plate, the test position of the roller under test can be easily adjusted, which is beneficial for obtaining multi-dimensional data for reference.

[0023] The roller inspection device provided in this embodiment of the utility model can, in some other embodiments, also detect the uniformity of the gap between two rollers by bringing them close together, thereby visually reflecting the effect of the finished product in the middle position. Specifically, an auxiliary roller can be rotatably arranged between the two vertical plates 1, and the auxiliary roller and the roller to be inspected are arranged parallel to each other and close to each other. In order to achieve coordinated transmission between the two, a gear set 2 that can mesh with each other is provided at the ends of the auxiliary roller and the roller to be inspected. (Refer to...) Figure 2 As shown, the first driving device 3 is configured to drive one gear in the gear set 2 to rotate. When the meshing gears rotate relative to each other, test material can be fed into the gap between the auxiliary roller and the roller to be tested to determine whether the transmission gap between them is uniform, thus providing an additional means of observation for visual inspection. The test material can be a composite material made of carbon paper and ordinary paper. The carbon paper imprints a deeper depth at smaller gaps, which helps to determine the overall gap change of the paper after passing through the gap.

[0024] This utility model provides a roller inspection device. To facilitate stable transport of the test material, the roller inspection device further includes a transfer plate 14 connected to a support frame. The transfer plate 14 has two sets of parallel first transmission wheels and a second drive device 15 for driving two transmission belts 16 to move synchronously. The second drive device 15 includes a transmission shaft rotatably mounted on the transfer plate 14, two first transmission wheels coaxially mounted on the transmission shaft, two second transmission wheels rotatably mounted on the transfer plate 14, and a motor for driving the transmission shaft. The first and second transmission wheels are connected by transmission belts 16. Furthermore, the transmission belts 16 are located within a groove on the transfer plate 14 to lower the position of the transmission surface of the transmission belts 16, making it as flush as possible with the upper surface of the transfer plate 14, thereby preventing the transported test material from bending.

[0025] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
