Description

Technical Field

[0001] This utility model relates to the field of stainless steel wire surface defect detection technology, and in particular to an online defect detection and marking device for stainless steel wire surface. Background Technology

[0002] Stainless steel wire may develop surface quality defects after heat treatment. During use, after uncoiling, the stainless steel wire requires visual inspection by a qualified inspector to prevent defective products from entering subsequent production lines. Manual inspection is inefficient and prone to omissions, resulting in defective products entering the production line. Furthermore, due to the lack of clear markings, a situation can easily occur: when producing product A, a coil of steel strip is loaded, and upon uncoiling, a quality defect affecting product A is discovered, but this defect does not affect product B and can be used for its production. In this case, the steel coil needs to be replaced.

[0003] A search revealed a smart detection and marking device for surface defects in stainless steel strip, with publication number CN222473705U. The device includes a servo motor, a control console, a steel strip rewinder, a coding printer bracket, a smart coding printer, and a camera. The coding printer bracket is a portal frame structure with a lead screw track as its crossbeam. The smart coding printer is mounted on the lead screw track. A servo motor and the control console are fixed to one side of the portal frame of the coding printer bracket, with the servo motor connected and fixed to the lead screw track. The steel strip rewinder is located behind the crossbeam of the coding printer bracket, and the camera is located in front of the crossbeam. During rewinding, the steel strip is taut and passes sequentially under the camera and the crossbeam of the coding printer bracket. The control console contains a control system and a control computer. The control computer stores a surface defect image library. By comparing the acquired surface defect images, the defect location coordinates and defect category are transmitted to the smart coding printer, which then controls the smart coding printer to print different marks on the defects on the steel strip.

[0004] The device in this patent can only detect the top of stainless steel products, resulting in incomplete detection. It requires a second detection of the bottom of the product, which increases the detection time or leads to the production of subsequent products, thus affecting the production quality of subsequent products. Utility Model Content

[0005] In response to the technical problems in existing patents, where the device can only detect the top side of stainless steel products, resulting in incomplete detection and requiring a second detection of the bottom side, thus increasing detection time, or directly proceeding to subsequent product production and affecting the production quality of subsequent products, this utility model provides an online defect detection and marking device for stainless steel wire surfaces.

[0006] The technical solution adopted by this utility model is: an online defect detection and marking device for stainless steel wire surface, comprising: a base and a detection and marking mechanism. The detection and marking mechanism includes a control console fixed on the upper side of the base, a mounting base fixed on the upper side of the base, a through mounting hole on one side of the mounting base, two guiding and conveying mechanisms disposed in the through mounting hole, two rotating rings rotatably fitted in the through mounting hole, and a driving mechanism disposed in the through mounting hole for driving the two rotating rings to rotate synchronously. The inner walls of the two rotating rings are respectively equipped with a data acquisition camera and a coding device, and the two rotating rings are located between the two guiding and conveying mechanisms.

[0007] Furthermore, the guiding and conveying mechanism includes two first electric push rods fixed to the inner wall of the through mounting hole, a roller seat located at the output end of the first electric push rods, and a roller located within the roller seat.

[0008] Furthermore, the drive mechanism includes a dual-axis extension servo motor disposed on the inner wall of the through mounting hole, two gears respectively disposed at both ends of the output shaft of the dual-axis extension servo motor, and two external gear rings respectively disposed on the inner sides of the two rotating rings, wherein the two gears mesh with the two external gear rings respectively.

[0009] Furthermore, a bearing corresponding to the rotating ring is provided in the through mounting hole, and the rotating ring is fixed in the bearing.

[0010] Furthermore, the upper side of the base is provided with an unwinding mechanism, which includes a U-shaped seat fixed on the upper side of the base, a take-up roller rotatably fitted in the U-shaped seat, and a servo motor located on one side of the U-shaped seat for driving the take-up roller to rotate.

[0011] Furthermore, the upper side of the U-shaped seat is provided with a placement groove, and both ends of the take-up roller are rotatably fitted in the placement groove. One end of the take-up roller is provided with a polygonal groove. The output shaft of the servo motor is a polygonal cylindrical structure, and the output shaft of the servo motor corresponds to the placement groove. A U-shaped electric push rod seat is provided on one side of the U-shaped seat, and a second electric push rod for driving the servo motor to slide is provided in the electric push rod seat.

[0012] The beneficial effects of this utility model are:

[0013] By positioning the acquisition camera and inkjet printer between the two guiding conveyor mechanisms, the stability of product transport between the two mechanisms is improved. This facilitates the acquisition of product information by the acquisition camera, reducing the probability that product shaking will affect the acquisition of product information by the acquisition camera, and also facilitates inkjet printing. By setting up a drive mechanism, acquisition camera, and inkjet printer, when the acquisition camera detects a product defect, the control console controls the inkjet printer to mark the defect, thereby completing the product inspection and marking. The dual-axis extension servo motor drives the external gear ring and rotating ring to rotate, which facilitates the intermittent, uniform, or variable speed rotation of the acquisition camera and inkjet printer around the product. This facilitates the inspection of the product's perimeter, improves the inspection effect, and avoids the problem of secondary inspection or uninspected areas affecting subsequent product production.

[0022] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0023] To address the problems existing in the background art, this application proposes the following technical solution:

[0024] An online defect detection and marking device for stainless steel wire surfaces includes: a base 1 and a detection and marking mechanism 2. The detection and marking mechanism 2 includes a control console 200 fixed on the upper side of the base 1, a mounting base 201 fixed on the upper side of the base 1, a through mounting hole 202 on one side of the mounting base 201, two guide conveying mechanisms 203 disposed in the through mounting hole 202, two rotating rings 204 rotatably engaged in the through mounting hole 202, and a drive mechanism 205 disposed in the through mounting hole 202 for driving the two rotating rings 204 to rotate synchronously. The inner walls of the two rotating rings 204 are respectively equipped with a data acquisition camera 206 and a coding device 207, and the two rotating rings 204 are located between the two guide conveying mechanisms 203.

[0025] Furthermore, the guiding and conveying mechanism 203 includes two first electric push rods 2031 fixed to the inner wall of the through mounting hole 202, a roller seat 2032 located at the output end of the first electric push rods 2031, and a roller 2033 located in the roller seat 2032.

[0026] In Example 1, the roller 2033 has a cylindrical structure, which facilitates the guidance and conveying of the stainless steel belt and makes it easier for the device to detect and mark the stainless steel belt;

[0027] In Example 2, the diameter of the roller 2033 gradually decreases from both ends to the middle, which facilitates the conveying and guiding of the stainless steel wire and makes it easier for the device to detect and mark the stainless steel wire.

[0028] Furthermore, the drive mechanism 205 includes a dual-axis extension servo motor 2051 disposed on the inner wall of the through mounting hole 202, two gears 2052 respectively disposed at both ends of the output shaft of the dual-axis extension servo motor 2051, and two external gear rings 2053 respectively disposed on the opposite inner sides of the two rotating rings 204, with the two gears 2052 meshing with the two external gear rings 2053 respectively.

[0029] Furthermore, a bearing 208 corresponding to the rotating ring 204 is provided inside the through mounting hole 202, and the rotating ring 204 is fixed inside the bearing 208.

[0030] Furthermore, the upper side of the base 1 is provided with an unwinding mechanism 3, which includes a U-shaped seat 301 fixed on the upper side of the base 1, a take-up roller 302 rotatably fitted in the U-shaped seat 301, and a servo motor 303 located on one side of the U-shaped seat 301 for driving the take-up roller 302 to rotate.

[0031] Furthermore, the upper side of the U-shaped seat 301 is provided with a placement groove 304, and the two ends of the take-up roller 302 are rotatably fitted in the placement groove 304. One end of the take-up roller 302 is provided with a polygonal groove 305. The output shaft of the servo motor 303 is a polygonal column structure, and the output shaft of the servo motor 303 corresponds to the placement groove 304. A U-shaped electric push rod seat 306 is provided on one side of the U-shaped seat 301, and a second electric push rod 307 for driving the servo motor 303 to slide is provided in the electric push rod seat 306.

[0032] Working principle: The coiled stainless steel strip or wire is placed on the U-shaped seat 301 by the take-up roller 302. Then, the second electric push rod 307 drives the output shaft of the servo motor 303 to insert into the polygonal groove 305, facilitating the unwinding of the take-up roller 302. The product passes through the through mounting hole 202 and is detected and marked in the detection and marking mechanism 2. The first electric push rod 2031 drives the roller seat 2032 to move the roller 2033 to fit against the product, which facilitates the improvement of product guidance and conveying stability by the two rollers 2033 in the guide conveying mechanism 203. The acquisition camera 206 and the inkjet printer 207 are set between the two guide conveying mechanisms 203 to improve the efficiency of the two guide conveying mechanisms 203. The stability of product conveying between 03 and 04 facilitates the acquisition of product information by the acquisition camera 206 and the printing of inkjet printer 207. When the acquisition camera 206 detects a product defect, it sends the information to the control console 200. The control console 200 controls the inkjet printer 207 to mark the defect, thereby completing the product inspection and marking. The dual-axis extension servo motor 2051 drives the external gear ring 2053 and the rotating ring 204 to rotate through the gear 2052. This facilitates the intermittent, uniform, and variable speed rotation of the acquisition camera 206 and the inkjet printer 207 around the product, which is convenient for inspecting the product's periphery. This improves the inspection effect and avoids the problem of secondary inspection or uninspected areas affecting subsequent product production.
