Description

A measuring auxiliary mechanism for insulating paper processing Technical Field

[0001] This invention relates to the field of insulating paper processing technology, specifically to a measuring auxiliary mechanism for insulating paper processing. Background Technology

[0002] Insulating paper is a paper material used for electrical insulation. It is usually made of cellulose fibers through special processes and has excellent electrical properties, mechanical strength and heat resistance. In order to ensure the performance of insulating paper, corresponding optical measuring instruments are usually used to detect the surface of the insulating paper during the production process.

[0003] For example, Chinese patent CN213275385U, entitled "A Device for Detecting Defects in Insulating Paper," published on May 25, 2021, includes a frame. A backlight plate parallel to the top plate is located between the two side plates of the frame. Insulating paper is placed between the top plate and the backlight plate. An image acquisition module is located on the side of the top plate facing the insulating paper. A backlight strip is located on the side of the backlight plate facing the insulating paper. A pair of angle-adjustable illumination lamps are symmetrically arranged on the two side plates, positioned above the insulating paper. The aforementioned prior art has the following technical problems:

[0004] Existing measuring devices are not convenient for cleaning impurities on the surface of insulating paper when detecting surface defects. When impurities adhere to the surface of the insulating paper, the optical measuring lens may misjudge the surface defects, thus affecting the reliability of the final test results. At the same time, when defects are detected on the surface of the insulating paper, it is not convenient to mark the defective areas. After subsequent measurements, it is easy to confuse the defective areas with the defective areas.

[0005] Therefore, we propose a measuring auxiliary mechanism for insulating paper processing to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a measurement auxiliary mechanism for insulating paper processing, in order to solve the problems mentioned above. Existing measuring devices on the market are not convenient for cleaning impurities on the surface of the insulating paper to be tested when detecting surface defects. When impurities are attached to the surface of the insulating paper, it is easy for the optical measuring lens to misjudge the surface defects of the insulating paper, thereby affecting the reliability of the final test results. At the same time, when defects are measured on the surface of the insulating paper, it is not convenient to mark the defective areas, which can easily lead to confusion between defective and non-defective areas after subsequent measurements.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a measuring auxiliary mechanism for insulating paper processing, comprising a support platform and a connecting frame mounted on the upper end of the support platform. An optical inspection lens module for detecting surface defects of the insulating paper is mounted on the connecting frame. An unwinding roller and a winding roller for conveying the insulating paper are mounted on the support platform, and both the unwinding roller and the winding roller are rotated by a motor. A self-cleaning component for treating surface impurities of the insulating paper is mounted on the support platform, and a control module electrically connected to the optical inspection lens module is mounted on the connecting frame. The control module controls the activation of a marking component to mark the defective areas on the surface of the insulating paper. Through the rotation of the unwinding roller and the winding roller, the insulating paper to be inspected can be automatically conveyed. Simultaneously, the optical inspection lens module on the connecting frame can automatically test the surface defects of the conveyed insulating paper.

[0008] Preferably, the self-cleaning component includes a guide seat, and a servo motor is mounted on the side of the guide seat. A reciprocating lead screw is mounted on the output end of the servo motor, and a support frame is mounted on the reciprocating lead screw. A cleaning roller is mounted on the support frame, and the cleaning roller has bristles arranged circumferentially. A transmission gear is mounted on the end of the cleaning roller, and a guide tooth plate fixed on a support platform is arranged below the transmission gear. An actuating rod is arranged above the cleaning roller, and a dust suction plate mounted on the support frame is arranged above the actuating rod. The dust suction plate is connected to a negative pressure device through a connecting hose.

[0009] By adopting the above technical solution, the bristles on the cleaning roller can remove impurities attached to the insulating paper.

[0010] Preferably, the lower end of the support frame and the reciprocating lead screw are threaded together, and the outer wall of the lower end of the support frame and the inner wall of the guide seat are in contact with each other, so that the support frame can slide on the guide seat.

[0011] By adopting the above technical solution, the sliding of the bearing frame on the guide seat can prevent the reciprocating screw from driving the bearing frame to rotate synchronously.

[0012] Preferably, the cleaning roller and the support frame are rotatably connected, and the transmission gear and the guide tooth plate on the central rotating shaft of the cleaning roller are meshed.

[0013] By adopting the above technical solution, when the support frame drives the cleaning roller to move, the meshing connection of the transmission gear and the guide tooth plate enables the cleaning roller to rotate on the support frame. The cleaning roller can assist in cleaning the stains on the surface of the insulating paper. At the same time, when the cleaning roller rotates on the support frame, the contact and disengagement between the brush bristles on the cleaning roller and the actuating rod can shake off the attached stains, and the dust suction plate can pick up the shaken-off impurities, thus realizing the automatic cleaning of the cleaning roller.

[0014] Preferably, the actuating lever is located between the bristles in the circumferential direction of the cleaning roller, and the bristles in the circumferential direction of the cleaning roller are made of elastic rubber.

[0015] By adopting the above technical solution, when the cleaning roller rotates, the impurities attached to the brush bristles can be shaken off by the contact and disengagement between the brush bristles and the actuating rod.

[0016] Preferably, the marking component includes a power cylinder and a piston plate fixed to the telescopic end of the power cylinder, and the piston plate is located inside the transfer box. The transfer box is connected to each other through a suction hose and a central tube, and the central tube is fixed on a support frame. The central tube is installed through the middle of the cleaning roller, and a branch pipe is fixed to one end of the central tube that extends into the cleaning roller. The interior of the cleaning roller is filled with marking pigment. The transfer box is connected to each other through an output hose and a spray head fixed on a connecting frame, and a one-way valve is installed on both the output hose and the suction hose.

[0017] By adopting the above technical solution, and through the one-way valves on the output hose and the suction hose, the backflow of marking pigment can be avoided.

[0018] Preferably, the piston plate is circumferentially fixed with a sealing ring, and the piston plate and the interior of the transfer box form a seamless sliding connection structure through the circumferential sealing ring.

[0019] By adopting the above technical solution, the piston plate can be used to reciprocate inside the transfer box to draw up the marking pigment inside the cleaning roller. The drawn-up marking pigment is then sprayed outward through the output hose and spray head onto the defective area on the insulating paper, thereby realizing the automatic marking of the defective location on the insulating paper.

[0020] Preferably, the cleaning roller is rotatable on the central tube, and the central tube and the suction hose are interconnected, with the one-way valves on the suction hose and the output hose having opposite flow directions.

[0021] By adopting the above technical solution, the cleaning roller can shake the marking pigment stored inside by moving back and forth with the support frame. At the same time, when the cleaning roller rotates, the central tube and branch tubes inside it can also mix the pigment inside the cleaning roller. This can prevent the pigment inside the cleaning roller from settling and stratifying due to long-term standing, which would affect the subsequent absorption and spraying of pigment.

[0022] Preferably, the branch pipes and the central pipe are vertically distributed, and multiple branch pipes are evenly distributed on the central pipe.

[0023] By adopting the above technical solution, the branch pipe can facilitate the absorption of marking pigment inside the cleaning roller, and at the same time, the branch pipe can be used to mix the marking pigment inside the cleaning roller when it rotates.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the measuring auxiliary mechanism for insulating paper processing can facilitate the auxiliary cleaning of the surface of the insulating paper to be tested when measuring the insulating paper, avoid the optical measuring lens from misjudging due to attached defects, and can also assist in marking the defective parts;

[0025] 1. Equipped with unwinding rollers and rewinding rollers, the insulation paper to be inspected can be automatically transported by the rotation of the unwinding rollers and rewinding rollers. At the same time, the surface defects of the conveyed insulation paper can be automatically tested by the optical inspection lens module on the connecting frame.

[0026] 2. Equipped with a cleaning roller, which can assist in cleaning stains on the surface of the insulating paper. When the cleaning roller rotates on the support frame, the contact and disengagement between the brush bristles on the cleaning roller and the actuating rod can shake off the attached stains. The dust collection plate then picks up the shaken-off impurities, thus achieving automatic cleaning of the cleaning roller.

[0027] 3. Equipped with a spray head, the piston plate reciprocates inside the transfer box to draw up the marking pigment inside the cleaning roller. The drawn-up marking pigment is then sprayed out through the output hose and spray head onto the defective area on the insulating paper, thus achieving automatic marking of the defective location on the insulating paper.

[0028] 4. Equipped with a central tube and branch tubes, the cleaning roller moves back and forth with the support frame, which allows the cleaning roller to shake the marking pigment stored inside. At the same time, when the cleaning roller rotates, the central tube and branch tubes inside it can also mix the pigment inside the cleaning roller. This can prevent the pigment inside the cleaning roller from settling and separating due to long-term standing, which would affect the subsequent absorption and spraying of pigment.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1: Referring to Figures 1-9, existing measuring devices are inconvenient for cleaning impurities on the surface of insulating paper when detecting surface defects. When impurities adhere to the surface of the insulating paper, the optical measuring lens may misjudge the surface defects, thus affecting the reliability of the final detection result. To solve this technical problem, this example discloses the following technical content: a measuring auxiliary mechanism for insulating paper processing, including a support platform 1 and a connecting frame 2 installed on the upper end of the support platform 1. An optical detection lens module 3 for detecting surface defects of insulating paper is installed on the connecting frame 2. An unwinding roller 4 and a winding roller 5 for transmitting insulating paper are installed on the support platform 1, and both the unwinding roller 4 and the winding roller 5 are controlled by a motor to rotate. A self-cleaning component 6 for treating surface impurities of insulating paper is installed on the support platform 1. The self-cleaning component 6 includes a guide seat 601, and a servo motor 602 is installed on the side of the guide seat 601. A reciprocating screw 603 is installed at the output end of the servo motor 602. A support frame 604 is mounted on 603, and a cleaning roller 605 is mounted on the support frame 604. The cleaning roller 605 has bristles arranged around its circumference. A transmission gear 606 is mounted at the end of the cleaning roller 605, and a guide tooth plate 607 fixed to the support platform 1 is located below the transmission gear 606. An actuating rod 608 is located above the cleaning roller 605, and a dust suction plate 609 mounted on the support frame 604 is located above the actuating rod 608. The dust suction plate 609 is connected to the negative pressure device via a connecting hose 610. The lower end of the support frame 604 and the reciprocating screw 603 are connected by threads, and the outer wall of the lower end of the support frame 604 and the inner wall of the guide seat 601 are in contact with each other. The support frame 604 can slide on the guide seat 601. The cleaning roller 605 and the support frame 604 are rotatably connected, and the transmission gear 606 and the guide tooth plate 607 on the central rotating shaft of the cleaning roller 605 are meshed. The actuating rod 608 is located between the bristles of the cleaning roller 605 in the circumferential direction, and the bristles of the cleaning roller 605 in the circumferential direction are made of elastic rubber.

[0041] When the insulating paper needs to be inspected, the unwinding roller 4 and the take-up roller 5 are installed on the support platform 1. The rotation of the unwinding roller 4 and the take-up roller 5 automatically feeds the insulating paper. During the feeding process, the optical inspection lens module 3 can optically inspect the defects on the surface of the insulating paper. During the inspection process, the servo motor 602 is turned on, which causes the reciprocating screw 603 to rotate. The rotation of the reciprocating screw 603 causes the threaded support frame 604 to reciprocate on the guide seat 601. The movement of the guide seat 601 causes the cleaning roller 605 on it to move synchronously. When the cleaning roller 605 moves, it is driven by the transmission gear 60 on the central rotating shaft. The meshing transmission between the 6 and the guide tooth plate 607 allows the cleaning roller 605 to rotate on the support frame 604. The cleaning roller 605 can clean the surface of the insulating paper conveyed below. When the cleaning roller 605 rotates, the bristles on it come into contact with the upper actuating rod 608, causing the bristles to bend elastically. When the bristles and the actuating rod 608 disengage, the bristles return to their original position through their own elasticity. The shaking of the bristles after returning to their original position can shake off the impurities attached to them. The shaken impurities can be absorbed by the dust collection plate 609, thereby ensuring the cleanliness of the insulating paper surface during subsequent testing, avoiding misjudgments by the optical inspection lens module 3 due to impurities on the insulating paper, and improving the accuracy of the final test results.

[0042] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. When defects are measured on the surface of the insulating paper, it is inconvenient to mark the defective areas. After subsequent measurements, it is easy to confuse the defective areas with the defect-free areas. To further solve this technical problem, this example discloses the following technical content: A control module 7 electrically connected to the optical detection lens module 3 is installed on the connecting frame 2. The control module 7 is used to control the marking component 8 to start and mark the defective areas on the surface of the insulating paper. The marking component 8 includes a power cylinder 801 and a piston plate 802 fixed on the telescopic end of the power cylinder 801. The piston plate 802 is located inside the transfer box 803. The transfer box 803 is connected to the central tube 805 through a suction hose 804. The central tube 805 is fixed on the support frame 604. A branch pipe 806 is fixed at one end of the central tube 805, which is installed through the middle of the cleaning roller 605 and extends into the interior of the cleaning roller 605. The interior of the cleaning roller 605 is filled with marking pigment. The transfer box 803 is connected to the spray head 808 fixed on the connecting frame 2 through the output hose 807. Both the output hose 807 and the suction hose 804 are equipped with one-way valves. A sealing ring is fixed circumferentially on the piston plate 802. The piston plate 802 and the interior of the transfer box 803 are connected seamlessly through the circumferential sealing ring. The cleaning roller 605 can rotate on the central tube 805. The central tube 805 and the suction hose 804 are interconnected. The one-way valves on the suction hose 804 and the output hose 807 have opposite flow directions. The branch pipes 806 and the central tube 805 are vertically distributed. Multiple branch pipes 806 are evenly distributed on the central tube 805.

[0043] When the optical inspection lens module 3 detects a defect on the surface of the insulating paper, the optical inspection lens module 3 activates its power cylinder 801 via the control module 7. The power cylinder 801 then pulls the piston plate 802, causing it to reciprocate inside the transfer box 803. This reciprocating movement of the piston plate 802 allows the suction hose 804, central tube 805, and branch tube 806 to draw the marking pigment from inside the cleaning roller 605. Simultaneously, the movement of the piston plate 802 transfers the pigment drawn from inside the transfer box 803 to the spray head 808 via the output hose 807. The spray head 808 then sprays the marking pigment. When the marking pigment reaches the defective area of ​​the insulating paper, and because the marking pigment is filled inside the cleaning roller 605, the cleaning roller 605 moves back and forth with the carrier frame 604, which can shake the marking pigment inside the cleaning roller 605. At the same time, when the cleaning roller 605 rotates for self-cleaning, it can use its internal central tube 805 and branch tube 806 to mix the marking pigment inside. Since the defects in the insulating paper are relatively rare, the mixing and shaking of the marking pigment inside the cleaning roller 605 can prevent the pigment from separating. This ensures that when it encounters defective markings on the insulating paper, the pigment will not become less fluid due to separation and sedimentation, which would affect the normal absorption and spraying of liquid.

[0044] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
