AI Technical Summary
Existing fiberglass looms are prone to warp breaks and fabric defects during the weaving process. Manual inspections are not timely, resulting in defects that cannot be detected and repaired in a timely manner, and labor costs are high.
By combining machine vision technology with weft insertion signals from the loom, images are captured at the weft insertion point using an industrial camera and LED line light source. The number and spacing of warp yarns are analyzed, warp breaks are automatically detected, and a stop signal is sent to prevent defects from occurring.
It enables early detection and automatic handling of warp breakage defects, reduces manual inspection work, improves fabric quality, and reduces labor intensity and costs.

TECHNICAL FIELD
[0001] The utility model relates to weaving equipment technical field, concretely is a glass fiber loom weaving mouth broken warp and cloth surface defect detection device. BACKGROUND
[0002] In the weaving process of glass fiber electronic cloth, due to yarn, loom and various factors, the cloth surface often produces various defects, for example, broken warp, skip, thick knot, weft shrinkage etc., these defects seriously affect the cloth surface quality, cause product to reduce the grade even scrap.
[0003] Years ago in order to solve the broken warp in the weaving process, the warp stopper is often used, that is, a warp stopper is hung on each warp yarn, and the warp stopper triggers the loom to stop when the warp yarn breaks. With the electronic cloth warp becoming thinner and thinner, the yarn abrasion caused by the warp stopper causes a large number of fluff on the cloth surface, resulting in a decrease in cloth surface quality, and a large amount of labor is needed to wear the warp stopper. At present, this method has been basically eliminated.
[0004] The existing detection method is mainly artificial inspection, and generally one operator is responsible for patrolling dozens of looms. The disadvantage of this method is poor real-time performance. When the cloth surface defect is found, the defect has been woven into the cloth surface for dozens of centimeters, becoming a fact, and cannot be repaired. Therefore, in view of the above problems, a glass fiber loom weaving mouth broken warp and cloth surface defect detection device is provided. UTILITY MODEL CONTENTS
[0005] The utility model aims at providing a glass fiber loom weaving mouth broken warp and cloth surface defect detection device to solve the problems in the above background technology.
[0006] To achieve the above object, the utility model provides the following technical scheme:
[0007] As an optional scheme of the glass fiber loom weaving mouth broken warp and cloth surface defect detection device, the glass fiber loom weaving mouth broken warp and cloth surface defect detection device comprises a loom;
[0008] The loom is provided with a heald frame above, and the inner side of the heald frame is provided with a warp yarn, and one end of the warp yarn is wound with a weaving shaft, and the two ends of the weaving shaft are rotatably connected with the loom.
[0009] The loom is also provided with an LED line light source on one side for lighting work;
[0010] The loom is also provided with a weft yarn on one side for weaving, and an industrial camera is arranged obliquely above the weft yarn.
[0011] As a kind of optional scheme of the glass fiber loom weaving port broken warp and cloth surface defect detection device provided by the utility model, wherein: the LED line light source is arranged obliquely and located above the place where weft and warp are interwoven.
[0012] Compared with prior art, the utility model has the beneficial effects that:
[0013] The utility model discloses a machine vision technology is used, cooperation loom beat-up signal is completed weaving port image acquisition, whether the broken warp occurs by analyzing warp number, spacing judges, after detecting the broken warp, loom is sent stop signal, and the broken warp defect is avoided on cloth surface;
[0014] Through the method, the broken warp defect of glass fiber electronic cloth in weaving process can be completely solved, the cloth surface defect is discovered as early as possible, manual processing is avoided, and the cloth surface defect is avoided.Meanwhile, manual machine inspection work is no longer needed, when the defect is found, manual processing is carried out in the corresponding machine, the quality of electronic cloth is guaranteed, manual cost is reduced, and labor intensity is reduced. BRIEF DESCRIPTION OF DRAWINGS
[0015] Figure 1 It is the whole structure schematic diagram of the utility model.
[0016] In the figure: 1-LED line light source, 2-harness frame, 3-industrial camera, 4-weft, 5-warp, 6-weaving shaft, 7-loom. DETAILED DESCRIPTION
[0017] The technical scheme in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.
[0018] Embodiment 1: please refer to Figure 1 The utility model provides a technical scheme:
[0019] A glass fiber loom weaving port broken warp and cloth surface defect detection device, including loom 7;
[0020] The upper side of the above-mentioned loom 7 is installed with harness frame 2, and the inner side of harness frame 2 is provided with warp 5, one end of warp 5 is wound with weaving shaft 6, and both ends of weaving shaft 6 are rotatably connected with loom 7;
[0021] The side of the above-mentioned loom 7 is also installed with LED line light source 1 for lighting work;
[0022] The loom 7 is further provided with weft yarns 4 for weaving, and the industrial camera 3 and the LED linear light source 1 are arranged obliquely above the weft yarns 4.
[0023] The LED linear light source 1 is arranged obliquely above the weft yarns 4 and the warp yarns 5.
[0024] In use, the latest five weft yarns on the cloth surface are analyzed to determine whether defects exist on the cloth surface, and when defects are found, a stop signal is sent to the loom, and the weft yarns are manually withdrawn to remove the defects on the cloth surface, and then the weaving is restarted.
[0025] The working process comprises the following steps:
[0026] Step 1: The industrial camera 3 and the LED linear light source 1 are installed above the weaving mouth of the loom 7, and when the loom 7 is started, the beating-up signal of the loom 7 triggers the industrial camera 3 to complete image acquisition of the weaving mouth once every weft yarn.
[0027] Step 2: The acquired weaving mouth images are transmitted to the computer through the gigabit network.
[0028] Step 3: The computer runs an image processing algorithm to identify broken warp defects and cloth surface defects.
[0029] Step 4: When the broken warp defects and the cloth surface defects are identified, the computer sends a stop signal to the loom 7, and the loom 7 stops working and alarms to prompt manual processing.
[0030] Step 5: The operator processes the exception and then restarts the weaving process.
