Description

Technical Field

[0001] The invention relates to the technical field of rubber cloth thickness measurement, in particular to a rubber cloth laser thickness measuring instrument and method. Background Art

[0002] With the widespread application of rubber materials in industrial conveying, sealing, and coating, the quality of rubber cloth, a fundamental intermediate carrier, directly impacts the performance and stability of downstream products. During mass production, rubber cloth undergoes multiple steps, including continuous tensioning and conveying, cleaning and dust removal, thickness testing, marking, and rewinding. Process precision and automation are crucial for improving production efficiency and product yield.

[0003] During the production process of existing rubber cloth, motor-driven rollers are often used for conveying, dust is removed by fixed cleaning devices, and a thickness gauge is configured to detect material thickness. Most of these functions are distributed in multiple independent devices and work through independent drive sources.

[0004] However, existing rubber cloth laser thickness gauges typically use a brush for cleaning. This single cleaning method has significant blind spots, resulting in incomplete cleaning when encountering microparticles or uneven surfaces. This inadequate cleaning of the cloth surface directly affects subsequent inspection accuracy. Furthermore, most devices typically perform only a simple scan, often requiring manual effort to mark unqualified areas. Therefore, the present invention provides a rubber cloth laser thickness gauge and method to address these shortcomings of the prior art. Summary of the Invention

[0008] Preferably, the cleaning mechanism includes a sleeve, the outside of the sleeve is mounted on the top of the supporting frame, the inner wall of the sleeve is slidably connected to a piston, one side of the piston is fixedly connected to a limiting slider, a spring is provided inside the sleeve, one end of the spring is fixedly connected to the outside of the piston, the end of the spring away from the piston is fixedly connected to the inner wall of the sleeve, the inner wall of the sleeve is fixedly connected to an air outlet pipe, a cleaning brush is fixedly connected to the top of the supporting frame, the end of the air outlet pipe away from the sleeve is arranged on the side of the cleaning brush, and an air inlet pipe is installed on the side of the sleeve away from the air outlet pipe.

[0009] Preferably, the collection mechanism includes a mounting plate, which is arranged on one side of the supporting frame. Motor 2 is installed on the outside of the mounting plate, and the output end of motor 2 is fixedly connected to driving gear 2. The inner wall of the mounting plate is rotatably connected to two collecting rollers, and the outside of the collecting roller is fixedly connected to driven gear 2, and the two driven gears 2 are meshed and connected to the outside of driving gear 2.

[0010] Preferably, the detection mechanism includes an electric slide rail 1, the outside of which is installed on the top of the support frame, an electric slider 1 is provided on the outside of the electric slide rail 1, a thickness gauge is installed on the outside of the electric slider 1, and the thickness gauge is connected to the control module via telecommunications.

[0012] Preferably, valves are installed inside the air outlet pipe and the air inlet pipe, and the end of the limiting slider away from the sleeve contacts the protrusion.

[0013] Preferably, the control module includes a data receiving unit, a judgment unit, a threshold adjustment unit and a drive control unit. The data receiving unit is used to receive the rubber cloth thickness information collected by the detection mechanism. The judgment unit is used to compare the rubber cloth thickness information with the thickness standard set by the threshold adjustment unit to determine whether it is an unqualified product. When it is judged to be unqualified, the drive control unit controls the marking mechanism to mark the surface of the unqualified rubber cloth. The threshold adjustment unit is used to dynamically set the thickness judgment threshold according to a preset material type or operation instruction.

[0014] A rubber cloth laser thickness measurement method is also provided, comprising the following steps:

[0015] By starting the motor 1, the driving gear 1 is driven to rotate, which in turn drives the driven gear 1 to rotate through the chain transmission, and further drives the rotating rod to rotate, thereby driving the external fixed conveying roller to rotate, thereby realizing the tensioning and conveying of the rubber cloth between the two tensioning rollers;

[0016] The rotation of the rotating rod synchronously drives the pulley 1 fixed at the other end to rotate, and cooperates with the belt to drive the pulley 2 to rotate, so that the connecting rotating rod and the turntable rotate accordingly, driving the two protrusions on the outside to rotate periodically. When the protrusions rotate to the corresponding position, they contact the limit slider and push it to move, driving the piston to slide along the inner wall of the sleeve to compress the spring. Then, the piston is reset under the action of the spring restoring force and forms an air pressure pulse, which pushes the air outlet pipe to discharge the air and cooperate with the cleaning brush to blow and clean the surface of the rubber cloth. At the same time, the air intake pipe controls the air intake path through the valve installed inside.

[0017] After the rubber cloth is sent to the bottom of the detection mechanism, the electric slide rail 1 drives the electric slider 1 to move horizontally so that the thickness gauge scans the thickness information of the rubber cloth surface outside it and transmits it to the control module in real time through telecommunications. The data receiving unit in the control module receives the thickness data, and the judgment unit compares the received thickness data with the thickness standard preset in the threshold adjustment unit or dynamically set according to the material type. When it is judged to be an unqualified product, the drive control unit sends a control signal to the marking mechanism, and the electric guide rail 2 drives the electric slider 2 to move to the specified position, so that the marking pen completes the unqualified mark at the corresponding rubber cloth position. After the inspection, the rubber cloth continues to be transported to the collection mechanism area, and the motor 2 drives the driving gear 2 to rotate, and at the same time drives the two meshing driven gears 2 to rotate in conjunction with the two collecting rollers, so that the inspected rubber cloth is rolled in to complete the collection process.

[0018] The present invention provides a rubber cloth laser thickness measuring instrument and method. It has the following beneficial effects:

[0019] 1. The present invention uses a rotating rod to link the pulley and the turntable structure, driving the bump to periodically compress the piston assembly to form an air pressure pulse, and discharge the air flow through the outlet pipe to clean the surface of the rubber cloth. At the same time, the air inlet path is precisely controlled by the valve. In this way, the air pressure pulse purge structure is used to achieve the technical effect of synchronously cleaning the surface of the rubber cloth, solving the problems of incomplete cleaning and low efficiency in the existing technology.

[0020] 2. The present invention uses an electric slide rail to drive a thickness gauge to scan the thickness of the rubber cloth and sends the data to the control module in real time. The judgment unit judges the product quality by comparing it with the standard thickness. If it is a defective product, the marking mechanism automatically marks it and finally completes automatic collection. In this way, the use of intelligent detection and automatic marking solutions achieves the technical effect of quickly identifying and marking defective products, solving the problems of low efficiency and high error rate of existing manual inspection.

[0021] 3. The present invention starts the motor to drive the driving gear, chain, rotating rod and conveying roller in linkage, so that the rubber cloth is tensioned and conveyed between the two tensioning rollers, keeping the force on the material uniform and the conveying stable during the operation. In this way, the chain linkage drive structure is adopted to achieve the technical effect of stable tensioning and conveying of the rubber cloth, solving the problems of easy deviation of the cloth and unstable tension in the prior art.

When the protrusions (405) rotate to the corresponding position, they contact the limiting slider (501) and push it to move, driving the piston (503) to slide along the inner wall of the sleeve (502) to compress the spring (504). Subsequently, the piston (503) is reset under the action of the restoring force of the spring (504) and forms an air pressure pulse, pushing the air outlet pipe (505) to discharge the air flow and cooperate with the cleaning brush (508) to blow and clean the surface of the rubber cloth. At the same time, the air inlet pipe (506) controls the air inlet path through the valve (507) installed inside. After the rubber cloth is sent to the bottom of the detection mechanism (3), the electric slide rail 1 (301) drives the electric slider 1 (302) to move horizontally so that the thickness gauge (303) scans the thickness information of the rubber cloth surface outside it and transmits it to the control module in real time through telecommunication. The data receiving unit in the control module receives the thickness data, and the judgment unit compares the received thickness data with the thickness standard preset in the threshold adjustment unit or dynamically set according to the material type. When it is judged to be a non-conforming product, the driving control unit sends a control signal to the marking mechanism (7), and the electric guide rail 2 (702) drives the electric slider 2 (703) to move to the specified position, so that the marking pen (704) completes the non-conforming mark at the corresponding rubber cloth position. The rubber cloth after completion of the inspection is continuously transported to the collection mechanism (6) area, and the motor 2 (602) drives the driving gear 2 (603) to rotate, and at the same time drives the two meshing driven gears 2 (604) to rotate in conjunction with the two collecting rollers (605), so that the rubber cloth after inspection is rolled in to complete the collection process.
