[0002] As a key component of floor cleaning robots, the roller plays a crucial role in floor cleaning, wastewater recovery, improving cleaning efficiency, protecting the floor, self-cleaning functions, and adapting to different floor types, directly impacting the robot's performance and user experience. However, during the roller manufacturing process, mechanical forces can easily cause deformation, breakage, or surface damage to the roller's inner core.

Detailed Implementation Methods

[0029] The following is in conjunction with the appendix Figure 1-9 The present invention will be further described in detail with reference to the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0030] Figure 1-9 The device shown for detecting the length of the inner core of a roller includes a worktable 1, a detection mechanism 2 for detecting the length of the inner core of the roller, and a fixing mechanism 3 for fixing the inner core of the roller. The fixing mechanism 3 is provided with a first fixing member 33 and a second fixing member 34 for engaging the inner core head.

[0031] In this implementation, the workbench serves as the foundation of the entire device, providing support and fixation. The first and second fixing parts of the inspection and fixing mechanism work together to engage the inner core head of the roller, ensuring that the inner core remains stable during the inspection process and reducing errors. Then, the inspection mechanism performs relative movement to accurately measure the length of the inner core of the roller, improving the accuracy of length detection.

[0032] Furthermore, both the first fixing member 33 and the second fixing member 34 are provided with fixing grooves 36 for engaging the inner core head.

[0033] In this embodiment, through the control of the fixing mechanism, the first and second fixing members can cooperate with each other, so that the fixing grooves on them can be precisely matched, thereby accurately positioning and firmly locking the inner core head of the roller. Specifically, the fixing groove 36 is V-shaped, and the V-shaped groove can provide good clamping force and stability. The fixing groove is not limited to this shape. For different types or specifications of inner core heads, the shape and size of the fixing groove can be adjusted accordingly to ensure a good clamping effect.

[0034] Furthermore, the fixing mechanism 3 includes a first connecting block 31 connected to the workbench 1 and a fixing clamp 32 connected to the first connecting block 31.

[0035] Furthermore, the fixing clamp 32 is provided with a movable block 35 for controlling the movement of the first fixing member 33 and the second fixing member 34.

[0036] Specifically, the movable block 35 is provided with a limiting groove 351 for fixing the first fixing member 33 and the second fixing member 34.

[0037] In this implementation, the movable block drives the first and second fixing members to move, controlling the opening and closing state of the fixing members to achieve clamping and releasing of the inner core head; by setting a limiting groove on the movable block, a clear installation position is provided for the fixing members, ensuring that the fixing members can move in a predetermined manner and achieve misalignment, thereby forming a shape such as when closed. Figure 6 The circular hole 10 shown is matched with the shape of the inner core head to provide better clamping force and achieve a firm snap-fit.

[0038] Furthermore, the detection mechanism 2 includes a first detection mechanism 5 and a second detection mechanism 6 for detecting the length of the inner core of the drum.

[0039] In this implementation, the first and second detection mechanisms work together, each contacting both ends of the inner core of the drum, and the second detection mechanism is used as a reference point to achieve high-precision measurement of the length of the inner core of the drum.

[0040] Furthermore, the first detection mechanism 5 includes a first active component 51 for controlling the activity and a detection component 52 for detecting the length.

[0041] Furthermore, the first movable component 51 includes a first slide rail 511 disposed on the worktable 1, a first movable slider 512 that moves vertically relative to the first slide rail 511, and a first cylinder 513 that provides power to the first movable slider 512.

[0042] The detection component 52 includes a second movable block 521 connected to the first movable slider 512, a detection element 522 passing through the second movable block 521, and a sensor 523 connected to the detection element 522 and used to acquire data.

[0043] In this embodiment, the first movable slider is pushed by the first cylinder to move vertically along the first slide rail, which in turn drives the second movable block to move vertically relative to it. This allows the detection piece to contact the surface of the inner core when it moves downward. The position change of the detection piece is monitored in real time by the sensor, and measurement data is output at the same time.

[0044] Furthermore, the second detection mechanism 6 includes a positioning component 61 for positioning and a second active component 62 for controlling the movement of the positioning component 61.

[0045] Furthermore, the positioning component 61 includes a third slide rail 611 disposed on the base 7 and a third movable slider 612 that moves vertically relative to the third slide rail 611.

[0046] Specifically, the third movable slider 612 is provided with a third inclined surface 6121 and a fourth inclined surface 6122 (for a more intuitive representation, Figure 9 (Some components are hidden), the third movable slider 612 is connected to a reference rod 613 for positioning the reference point and a reset spring 614 for protecting the second detection mechanism 6.

[0047] Furthermore, the second movable component 62 includes a second slide rail 621 disposed on the base 7, a second movable slider 622 that moves horizontally relative to the second slide rail 621, and a second cylinder 623 that provides power to the second movable slider 622.

[0048] Specifically, the second movable slider 622 is provided with a first inclined surface 6221 that abuts against the third inclined surface 6121, and a second inclined surface 6222 that abuts against the fourth inclined surface 6122 (for a more intuitive representation, Figure 9 (Some components are hidden).

[0049] In this implementation, the second movable slider is driven by the second cylinder to move horizontally along the second slide rail. The interaction between the third and fourth inclined surfaces of the second movable slider and the first and second inclined surfaces of the third movable slider causes the third movable slider to move vertically relative to the third slide rail. This third movable slider drives the reference rod upwards, contacting and fixing one end of the inner core as a reference point, thus achieving precise setting of the reference point and ensuring the accuracy of the measurement results. Secondly, a return spring provides a protection mechanism. Through the coordinated action of the return spring, the second movable slider, and the third movable slider, the precise setting of the reference point is achieved, ensuring the stability of the third movable slider in the working state and its return to its initial position in the non-working state.

[0050] When using this utility model,

[0051] First, the roller 8 is fixedly placed on the testing table 9. The inner core head of the roller 8 is clamped by the fixing mechanism 3. The testing mechanism 2 is started. The reference rod 613 of the second testing mechanism 6 moves upward relative to the positioning hole 91 on the testing table 9 and contacts the other side of the inner core of the roller 8. The measurement reference point is set. The detection element 522 of the first testing mechanism 5 contacts the inner core head of the roller 8. The position change of the detection element is monitored in real time by the sensor, and the measurement data is output at the same time.

[0052] This invention relates to a device for detecting the length of a roller core. A fixing mechanism ensures the stability of the roller core, while a detection mechanism accurately measures the roller length. The cooperation between the fixing and detection mechanisms improves the efficiency, accuracy, and stability of roller core length detection, and reduces errors caused by core movement or vibration. This device can meet the requirements of large-scale production environments and different detection needs, and solves the problem of poor accuracy in current roller core length detection.
