Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of glass fiber testing equipment, and in particular to a fabric inspection machine for detecting surface defects in glass fiber cloth production. Background Technology
[0002] During the production of fiberglass cloth, various defects can easily appear on its surface due to factors such as fluctuations in raw material quality, precision issues with production equipment, and the complexity of the production process. These defects include, but are not limited to, scratches, stains, holes, fiber breaks, or unevenness. These surface defects not only affect the appearance quality of the fiberglass cloth but also severely weaken its physical and performance characteristics. For example, in the electronics field, surface defects in fiberglass cloth used in circuit board manufacturing can lead to unstable electrical performance of the circuit boards, affecting the reliability and lifespan of electronic products. In the aerospace field, as a component of structural materials, surface defects in fiberglass cloth can reduce the material's strength and durability, posing a potential threat to aircraft safety.
[0003] In existing technologies, when fiberglass cloth moves on a fabric inspection machine, operators stand on one or both sides of the machine and visually inspect the surface of the cloth. They carefully check for various defects such as scratches, stains, holes, fiber breaks, or unevenness. However, some existing devices lack meter counting for the inspected fiberglass cloth, making it impossible to rationally plan subsequent production tasks, causing production chaos and affecting the efficiency of the entire production line. Therefore, a fabric inspection machine for detecting surface defects in fiberglass cloth production is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a fabric inspection machine for detecting surface defects in glass fiber cloth production, aiming to improve the problem that some existing devices cannot count the length when inspecting glass fiber cloth.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A fiberglass cloth surface defect detection machine includes a base, a support frame fixedly connected to the top of the base, a rotating roller rotatably connected inside the support frame, a drive shaft rotatably connected inside the support frame, an eccentric wheel fixedly connected to the right side of the drive shaft, a mounting frame fixedly connected inside the base, a sliding rod slidably connected inside the mounting frame, a spring sleeved on the outside of the sliding rod, a rotating frame one rotatably connected inside the mounting frame, a pawl one slidably connected to the outside of the rotating frame one, a pawl two slidably connected to the outside of the rotating frame one, two metering discs rotatably connected inside the mounting frame, two ratchet wheels rotatably connected inside the mounting frame, a rotating frame two rotatably connected to the rear side of the support frame, and a rotating assembly for controlling the swing of the rotating frame two is provided inside the support frame.
[0007] The device starts up, causing the rotating roller to rotate, which in turn drives the transmission shaft to rotate the cam. This intermittently pushes the sliding rod up and down, which in turn drives the rotating frame to rotate. The pawl on the rotating frame pushes the ratchet to rotate, and the ratchet is fixedly connected to the metering disc to achieve length recording.
[0008] As a further description of the above technical solution:
[0009] A detection light is fixedly connected to the top of the support frame, and a guide wheel is fixedly connected to the front side of the support frame.
[0010] The uniform illumination of the fiberglass cloth by the detection lamp provides a good light source environment for assisting manual inspection. The guide rollers provide a certain limiting foundation and pressure for the flowing fiberglass cloth, enabling it to spread evenly and facilitating manual inspection.
[0011] As a further description of the above technical solution:
[0012] The top of the base is fixedly connected to a fixing frame, and the outside of the fixing frame is slidably connected to two sliding support shafts.
[0013] Fiberglass cloths of different widths can be mounted on the top of the equipment via a fixed frame and internal sliding support shafts, allowing them to rotate between the two sliding support shafts and enabling their rotation and unfolding.
[0014] As a further description of the above technical solution:
[0015] The top of the eccentric wheel contacts the bottom of the sliding rod, and the outside of the sliding rod contacts the inside of the rotating frame.
[0016] The rotation of the eccentric wheel regularly pushes the sliding rod upward, and the spring sleeved on the outside of the sliding rod pushes the sliding rod downward. The sliding of the sliding rod drives the rotating frame to swing back and forth, realizing the regular meshing of the subsequent structure.
[0017] As a further description of the above technical solution:
[0018] The outer side of the first pawl engages with the inner side of one of the ratchet wheels, the outer side of the second pawl engages with the inner side of the other ratchet wheel, and the right sides of the two metering discs are respectively fixedly connected to the left sides of the two ratchet wheels.
[0019] Pad 1 and Pad 2 engage with the ratchet wheel, driving the metering disc to rotate, thus achieving the function of recording length. Pad 2 is smaller than Pad 1, so it only drives the ratchet wheel to rotate one increment when it rotates one revolution, thus achieving the effect of carrying over.
[0020] As a further description of the above technical solution:
[0021] A pulley is fixedly connected to the outside of the roller, and the other end of the pulley is fixedly connected to the outside of the drive shaft.
[0022] Power is transmitted through the connection of pulleys, so that the power of the rotating roller drives the drive shaft to rotate, which in turn drives the subsequent counting components.
[0023] As a further description of the above technical solution:
[0024] The rotating assembly includes a motor, the bottom of which is fixedly connected to the inside of the support frame, and a worm gear is fixedly connected to the drive end of the motor.
[0025] The motor provides power to the rotating components, and the rotation of the drive end drives the worm gear to rotate, thereby driving the subsequent structure to produce a reciprocating oscillating motion.
[0026] As a further description of the above technical solution:
[0027] A cam is fixedly connected to the right side of the rotating frame 2. A rotating bar is rotatably connected to the right side of the cam. A worm gear is rotatably connected to the left side of the rotating bar. The outside of the worm gear meshes with the outside of the worm.
[0028] The worm gear drives the worm wheel to rotate, which in turn causes one end of the rotating bar to make a circular motion, pulling one end of the cam to make a reciprocating oscillating motion, and finally causing the rotating frame to oscillate back and forth, so that the inspected fiberglass cloth inside can be stacked back and forth.
[0029] This utility model has the following beneficial effects:
[0030] 1. In this utility model, the rotation of the rotating roller drives the belt pulley to rotate the transmission shaft, which in turn drives the eccentric wheel to rotate. The sliding rod is intermittently lifted and slides inside the mounting frame, while the outer spring drives the sliding rod to return to its original position. This intermittently pushes the rotating frame to swing back and forth, which in turn drives the pawl to push one of the ratchet wheels to rotate, which in turn drives a meter counter to rotate. The rotation displays the length of the fabric, which helps to count the fabric length and facilitates reasonable statistics.
[0031] 2. In this utility model, the worm gear is driven to rotate by the motor drive end, which in turn drives the worm wheel to rotate, which in turn pulls one end of the rotating bar to produce a relative circular motion, and finally drives the other end of the cam to produce a reciprocating oscillating motion, which drives the rotating frame to oscillate, so that the fiberglass cloth passing through can be regularly oscillated and stacked, avoiding storage disorder and facilitating subsequent packaging and transportation.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0039] Reference Figure 1 This utility model provides an embodiment of a fiberglass cloth surface defect detection machine, comprising a base 1, which is the basic support of the entire machine, possessing a certain weight and stability to ensure that the machine does not easily shake or shift during the inspection process, providing a reliable support platform for the components above. A support frame 2 is fixedly connected to the top of the base 1. The support frame 2 is generally welded from metal pipes or profiles, possessing high strength and rigidity, providing installation space for the subsequent lifting and pouring structure. A rotating roller 6 is rotatably connected inside the support frame 2. The roller 6 is typically cylindrical, with a smooth surface and a certain degree of hardness. Its main function is to guide the fiberglass cloth to move smoothly on the inspection machine, allowing it to pass smoothly through the inspection area through its own rotation. A drive shaft 7 is rotatably connected inside the support frame 2. The drive shaft 7 is a key component for transmitting power, providing power to the subsequent metering components. An eccentric wheel 9 is fixedly connected to the right side of the drive shaft 7. The eccentric wheel 9 is circular in shape, but its rotation center does not coincide with its geometric center. When the drive shaft 7 drives the eccentric wheel 9 to rotate, due to the eccentric structure, a periodic reciprocating motion will be generated.
[0040] Reference Figures 1 to 3 The base 1 has a fixed mounting bracket 10 inside, which provides a mounting base for the subsequent metering components. A sliding rod 11 is slidably connected inside the mounting bracket 10. The sliding rod 11 is V-shaped and rotates the internal structure of the mounting bracket 10 by sliding up and down. A spring 12 is sleeved on the outside of the sliding rod 11, providing a reaction force to push the sliding rod 11 downwards. A rotating frame 13 is rotatably connected inside the mounting bracket 10. A pawl 14 and a pawl 2 are slidably connected to the outside of the rotating frame 13. The rotation of the rotating frame 13 drives the pawls 14 and 15 to rotate downwards. Pawl 15 generates relative motion, driving the subsequent structure to rotate uniformly. The mounting frame 10 has two rotatable measuring discs 16 inside. The measuring discs 16 are usually circular discs with scales or numbers on their surface, used to measure the length of the fiberglass cloth. The mounting frame 10 also has two rotatable ratchet wheels 17 inside. The ratchet wheels 17 are wheels with a special tooth structure. They work in conjunction with pawl 14 and pawl 15 to achieve unidirectional intermittent rotational motion. The support frame 2 has a rotating frame 18 rotatably connected to its rear side. The support frame 2 has a rotating component inside to control the swaying of the rotating frame 18.
[0041] Reference Figures 2 to 3Pad 14 engages with the interior of one of the ratchet wheels 17, and pad 25 engages with the interior of the other ratchet wheel 17. This engagement allows pad 14 and pad 25 to apply a unidirectional force to the ratchet wheels 17. When pad 14 moves with the rotating frame 13, it pushes the ratchet wheel 17 to rotate in a specific direction. The right sides of the two measuring discs 16 are fixedly connected to the left sides of the two ratchet wheels 17, which drive the measuring discs 16 to rotate and update the length readings. A pulley 8 is fixedly connected to the exterior of the rotating roller 6, and the other end of the pulley 8 is fixedly connected to the exterior of the drive shaft 7. The main function of the pulley 8 is to transmit power to other components through the belt drive system to achieve coordinated operation between the rotating roller 6 and the drive shaft 7.
[0042] Reference Figure 1 A detection lamp 3 is fixedly connected to the top of the support frame 2. The main function of the detection lamp 3 is to provide sufficient and uniform illumination to the surface of the fiberglass cloth so that the inspectors or related inspection equipment can clearly observe the condition of the cloth surface. The emitted light may have a specific wavelength and brightness range, which can highlight defects on the surface of the fiberglass cloth, such as scratches, stains, and holes. A guide wheel 24 is fixedly connected to the front side of the support frame 2. The main function of the guide wheel 24 is to guide the direction of the fiberglass cloth so that it can smoothly enter the inspection area of the cloth inspection machine. A fixing frame 4 is fixedly connected to the top of the base 1. Two sliding support shafts 5 are slidably connected to the outside of the fixing frame 4. The function of the sliding support shafts 5 is to provide additional support for the fiberglass cloth during the cloth inspection process, so that it can roll and unfold.
[0043] Reference Figure 4 The rotating assembly includes a motor 19, the bottom of which is fixedly connected to the inside of the support frame 2. The function of the motor 19 is to provide a power source for the swinging of the rotating frame 18. It can convert electrical energy into mechanical energy to drive the subsequent transmission components. The drive end of the motor 19 is fixedly connected to a worm gear 20. When the motor 19 is running, it can drive the worm gear 20 to rotate synchronously. The right side of the rotating frame 18 is fixedly connected to a cam 21. The function of the cam 21 in the rotating assembly is to convert the rotational motion into the swinging motion. The right side of the cam 21 is rotatably connected to a rotating bar 22. The rotating bar 22 is used to convert the rotational motion of the subsequent structure into the circular motion. The left side of the rotating bar 22 is rotatably connected to a worm wheel 23. The outside of the worm wheel 23 meshes with the outside of the worm gear 20, thereby realizing that the motor 19 drives the worm gear 20 to rotate.
[0044] Working principle: First, the fiberglass cloth is placed between the two sliding support shafts 5. The cloth end is manually passed through the rotating roller 6, the bottom of the sliding support shaft 5 and the inside of the rotating frame 18. The machine is turned on to make the fiberglass cloth roll in sequence. Then the power of the detection lamp 3 is turned on to illuminate every part of the cloth. After manual inspection, the cloth inspection operation is completed.
[0045] Secondly, when the machine rotates, it drives the rotating roller 6 to rotate, which in turn drives the belt pulley 8 to pull the transmission shaft 7 to rotate, causing the eccentric wheel 9 to rotate. This intermittently lifts the sliding rod 11, which slides inside the mounting frame 10. Meanwhile, the outer spring 12 drives the sliding rod 11 to return to its original position, thus intermittently pushing the rotating frame 13 to rotate. This, in turn, drives the pawl 14 to push one of the ratchet wheels 17 to rotate, causing a meter counter 16 to rotate and display the exposed length. The second pawl 15 is shorter than the first pawl 14. After one of the ratchet wheels 17 rotates once, the first pawl 14 engages in the groove inside the ratchet wheel 17, causing the second pawl 15 to move and push the other ratchet wheel 17 and the meter counter 16 to rotate, completing the meter count. The meter counter 16 can display the exposed length in real time, allowing operators to intuitively understand the fabric length information during fabric inspection. This helps to promptly grasp the production progress and perform statistical analysis.
[0046] Finally, the motor 19 is switched on, which drives the worm gear 20 to rotate, thereby driving the worm wheel 23 to rotate. This, in turn, pulls one end of the rotating bar 22 to produce a relative circular motion, which in turn drives the other end of the cam 21 to produce a reciprocating oscillating motion. This causes the rotating frame 18 to oscillate, allowing the fiberglass cloth to swing and stack in a regular manner. This avoids the unevenness and chaos caused by irregular stacking, and provides convenience for subsequent repair, sorting, packaging, transportation and use.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
