Description

Technical Field

[0001] The invention belongs to the technical field of slitting equipment with variable forms in the lithium battery industry, and specifically relates to a rubber roller outer diameter detection device and a detection calibration system. Background Art

[0002] A slitting machine is a mechanical device specially used for processing materials such as aluminum foil / copper foil. Its main function is to cut wide aluminum foil strips / copper foil strips into small strips of specific width for further processing or use. In the lithium battery industry, when slitting materials such as copper foil / aluminum foil, the wear on the surface of the roller in the transmission path will seriously affect the quality of the product. The current practice is that after the equipment has been worn out after a period of operation, the manufacturer will remove the rubber roller and grind the entire roller. At this time, it is necessary to understand the outer diameter of the rubber roller after grinding to facilitate recalibration of the motor speed. When personnel re-test the polished rubber roller, the equipment needs to be shut down and measurement time is reserved. This process is time-consuming and labor-intensive, and the accuracy and interval time of personnel measurement will affect production and quality. There is currently a lack of specialized testing tools. Summary of the invention

[0003] In view of this, an object of the present invention is to provide a rubber roller outer diameter detection device and a detection and calibration system to solve the deficiencies in the prior art.

[0004] In order to achieve the above object, the present invention is achieved through the following technical solutions:

[0005] On the one hand, a device for detecting the outer diameter of a rubber roller is provided, which includes a fixed connection mechanism, a driving mechanism, and a detection wheel and an encoder that are axially connected to each other. The driving mechanism, the detection wheel and the encoder are arranged on one side of the end of the rubber roller through the fixed connection mechanism. The detection wheel is tightly fitted with the rubber roller under the drive of the driving mechanism, and the rubber roller drives the detection wheel to rotate, and the detection wheel drives the encoder to rotate and measure and record relevant parameters.

[0006] As described in the rubber roller outer diameter detection device, wherein the fixed connection mechanism includes a fixed rod, a rotating plate group and a rotating rod, one end of the fixed rod is fixed to the external wall panel, the rotating plate group is rotatably connected to the other end of the fixed rod, one end of the rotating rod is axially connected to the detection wheel, and the other end passes through the rear axis of the rotating plate group to be connected to the encoder, and the driving mechanism drives the rotating plate group to rotate.

[0007] For example, in the rubber roller outer diameter detection device, the driving mechanism is a cylinder, a push rod is fixedly connected to the rotating plate group, the cylinder is fixed to the external wall panel, and the piston rod of the cylinder acts on the push rod.

After replacing the rubber roller, the encoder transmits the detected data parameters to the control center, and the control center calculates according to a preset program formula to obtain the outer diameter of the rubber roller and recalibrates the motor speed.

[0009] As described in the detection and calibration system, wherein the control center has a human-computer interaction interface, and the human-computer interaction interface is provided with a numerical display screen, a measurement button and a speed calibration button.

In addition, terms such as "first," "second," "third," etc., are used herein for illustrative purposes and are not intended to indicate or imply importance or significance.

[0020] See also Figure 1 As shown, in a preferred embodiment, the outer diameter detection device of the rubber roller of the present invention includes a fixed connection mechanism, a driving mechanism, and a detection wheel 1 and an encoder 2 that are axially connected to each other. The driving mechanism, the detection wheel 1 and the encoder 2 are arranged on one side of the end of the rubber roller 3 through the fixed connection mechanism. The detection wheel 1 is tightly fitted with the rubber roller 3 under the drive of the driving mechanism. The rubber roller 3 drives the detection wheel 1 to rotate, and the detection wheel 1 drives the encoder 2 to rotate and measure and record relevant parameters.

[0021] Continuing to refer to the figure, the fixed connection mechanism includes a fixed rod 4, a rotating plate group 5 and a rotating rod 6. One end of the fixed rod 4 is fixed to the external wall panel 7, and the rotating plate group 5 is rotatably connected to the other end of the fixed rod 4. One end of the rotating rod 6 is axially connected to the detection wheel 1, and the other end passes through the rear axis of the rotating plate group 5 to be connected to the encoder 2. The driving mechanism drives the rotating plate group 5 to rotate.

[0022] Furthermore, the driving mechanism is a cylinder 8 , a push rod 9 is fixedly connected to the rotating plate group 5 , the cylinder 8 is fixed to the external wall panel 7 (which can be achieved through a cylinder fixing part 10 ), and a piston rod of the cylinder 8 acts on the push rod 9 .

[0023] The present invention also relates to a detection and calibration system, including a control center and the above-mentioned rubber roller outer diameter detection device. After replacing a new or repaired rubber roller 3, the encoder 2 transmits the detected data parameters (rotation speed of the rubber roller 3) to the control center, and the control center converts it according to a preset program formula to obtain the outer diameter of the rubber roller 3.

[0024] The control center has a human-machine interaction interface, which is provided with a numerical display screen, a measurement button and a speed calibration button.

[0025] The workflow is as follows:

[0026] a. Remove the old rubber roller first, grind and repair it, and then reinstall it.

[0027] b. Measure the diameter of the rubber roller through the device: the program will remind you at the set time, click the measurement button, and the system will output the measured value of the outer diameter of the rubber roller.

[0028] An example of the calculation process of the outer diameter of the rubber roller: the rubber roller rotates N1 circles driven by the motor, and the detection wheel rotates with the rubber roller. The encoder detects that the detection wheel rotates N2 circles. The original detection wheel diameter Db1 is multiplied by the number of rotations N2 to obtain the total circumference of the detection wheel. The preliminary measurement result of the outer diameter of the rubber roller is D'=(Db1*N2) / (π*N1).

[0029] c. The test data is recorded in the system, and the system recalibrates the motor speed to maintain stable operation.

[0030] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
