[0028] DETAILED DESCRIPTION

[0029] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0030] like Figure 1 As shown, a defect detection module provided according to the present invention includes a support device 301, a visual detection device 302 and a detection fixture device 303. Both the support device 301 and the detection fixture device 303 are erected on the ground, and the detection fixture device 303 is located on one side of the width direction of the support device 301. The visual detection device 302 is slidably mounted on the support device 301, and the sliding direction of the visual detection device 302 is in the same direction as the length direction of the support device 301, and the visual detection device 302 is located above the detection fixture device 303.

[0031] like Figure 1 As shown, the support device 301 includes a support base 3011 and a movable rail 3012. The support base 3011 is erected on the ground, and the movable rail 3012 is laid on the top of the support base 3011. The length direction of the movable rail 3012 is in the same direction as the length direction of the support base 3011, and two movable rails 3012 are laid at intervals on the top of the support base 3011, thereby providing an installation basis for the visual detection device 302.

[0032] like Figure 2 and Figure 3As shown, the visual inspection device 302 includes a visual instrument 3021 and a mounting plate 3022. The mounting plate 3022 is horizontally mounted on two moving rails 3012 and slides with the two moving rails 3012 respectively. The two moving rails 3012 allow the mounting plate 3022 to slide horizontally along its length. A driving assembly 304 for driving the visual inspection device 302 to move on the supporting base 3011 is installed between the supporting device 301 and the visual inspection device 302. The driving assembly 304 includes a driving motor 3041, a gear 3042 and a rack 3043. The driving motor 3041 is fixedly mounted on the mounting plate 3022 by bolts, and the output shaft of the driving motor 3041 is horizontally arranged and extends out of the mounting plate 3022. The gear 3042 is coaxially fixedly installed on the end of the output shaft of the driving motor 3041, and the rack 3043 is horizontally fixedly installed on the top of the supporting base 3011. The rack 3043 is located on the side of the supporting base 3011 away from the detection fixture device 303. The rack 3043 is arranged parallel to the two moving rails 3012, and the rack 3043 is meshed with the gear 3042.

[0033] The driving motor 3041 is started to drive the gear 3042 to rotate. With the help of the engagement between the rack 3043 fixedly installed on the supporting base 3011 and the gear 3042 installed at the end of the output shaft of the driving motor 3041, the mounting plate 3022 slides on the two moving rails 3012 along the length direction of the moving rails 3012, thereby realizing the horizontal sliding movement of the visual inspection device 302 on the supporting device 301.

[0034] An instrument fixing frame 3023 is connected between the visual instrument 3021 and the mounting plate 3022. The instrument fixing frame 3023 is a metal frame with a certain structural strength and provides a mounting base for the visual instrument 3021. The instrument fixing frame 3023 includes a horizontal portion and a vertical portion. The horizontal portion is integrally formed at both ends of the vertical portion, and the horizontal portion located on the upper side extends from the connection between the horizontal portion and the vertical portion to the side close to the detection fixture device 303, and the horizontal portion located on the lower side extends from the connection between the horizontal portion and the vertical portion to the side away from the detection fixture device 303.

[0035] The visual instrument 3021 is suspended and fixed to the lower side of the horizontal part located on the upper side by bolts, and the horizontal part located on the lower side is movably mounted on the mounting plate 3022, and the mounting plate 3022 allows the instrument fixing frame 3023 to slide thereon. The second driving cylinder 305 is horizontally fixedly mounted on the mounting plate 3022 by bolts, and the extension direction of the output shaft of the second driving cylinder 305 is perpendicular to the length direction of the moving track 3012, and the end of the output shaft of the second driving cylinder 305 is fastened to the instrument fixing frame 3023. When the second driving cylinder 305 is started, the instrument fixing frame 3023 is driven to slide horizontally on the mounting plate 3022 in a direction perpendicular to the moving track 3012, thereby driving the visual instrument 3021 to slide horizontally in a direction perpendicular to the moving track 3012, thereby improving the convenience of the staff in adjusting the position of the visual instrument 3021.

[0036] The mounting plate 3022 is also fixedly mounted with a solenoid valve 306 . The solenoid valve 306 is electrically connected to the second driving cylinder 305 , and the solenoid valve 306 is used to control the opening, closing and movement of the second driving cylinder 305 .

[0037] When the visual instrument 3021 is working, the scanner on the visual instrument 3021 scans the snowboard fixedly mounted on the detection fixture, and the visual instrument 3021 divides the snowboard into three to five areas, preferably four areas, and drives the visual instrument 3021 to move along the length direction of the moving track 3012 through the cooperation of the driving motor 3041, the gear 3042 and the rack 3043, and then scans the four areas on the snowboard one by one. When the scanner on the visual instrument 3021 performs the scanning operation, each area is divided into multiple blocks, each block is 0.5mm interval, and the interval is distinguished by lines. The scanner transmits the scanning result to the processing module of the visual instrument 3021 for processing, and the processing module calculates the difference between the minimum value and the maximum value of the line. When the difference between the minimum and maximum values ​​of the line is less than or equal to 0.4mm, it is qualified; when the difference between the minimum and maximum values ​​of the line is greater than 0.4mm, it is unqualified; if the number of unqualified lines in each area of ​​the snowboard is less than 10 and discontinuous, it is a qualified product; if the number of unqualified lines in each area of ​​the snowboard is greater than 10, or is continuous and adjacent, it is an unqualified product. In this way, it is possible to detect whether the bottom surface of the ski board after grinding is completely ground, or to determine whether there are defects such as pits and cracks on the bottom surface of the ski board.

[0038] like Figure 4As shown, the detection fixture device 303 includes a detection fixture base 3031, a support suction cup 307, a pneumatic adsorption assembly 308, and a pneumatic support assembly 309. The detection fixture base 3031 is erected on one side of the support base 3011 in the width direction, the length direction of the detection fixture base 3031 is parallel to the length direction of the support base 3011, and the height of the detection fixture base 3031 is less than the height of the support base 3011. The support suction cup 307, the pneumatic adsorption assembly 308, and the pneumatic support assembly 309 are all fixedly mounted on the upper side wall of the detection fixture base 3031.

[0039] The supporting suction cup 307 includes a second supporting frame 3071 and a sixth suction cup 3072. The second supporting frame 3071 is vertically fixedly installed on the upper side wall of the detection fixture base 3031 by bolts. Seven second supporting frames 3071 are fixedly installed on the detection fixture base 3031 at intervals along the length direction of the detection fixture base 3031. One sixth suction cup 3072 is fixedly installed on the upper side of any second supporting frame 3071, and the openings of the seven sixth suction cups 3072 are all set upward.

[0040] There are three groups of pneumatic adsorption components 308 arranged at intervals on the detection fixture base 3031 along the length direction of the detection fixture base 3031, one of which is located at one side of the detection fixture base 3031 in the length direction, and the remaining two pneumatic adsorption components 308 are located in the middle of the detection fixture base 3031 and are arranged adjacently at intervals. There are three groups of supporting suction cups 307 between the pneumatic adsorption component 308 located at one side of the detection fixture base 3031 in the length direction and the pneumatic adsorption component 308 located in the middle of the detection fixture base 3031, and the three groups of pneumatic adsorption components 308 are arranged at intervals from the supporting suction cups 307.

[0041] Since the components, structures and installation methods of the three groups of pneumatic adsorption components 308 are the same, one group of pneumatic adsorption components 308 is taken as an example for explanation: the pneumatic adsorption component 308 includes a first cylinder 3081 and a fifth suction cup 3082, the first cylinder 3081 is fixedly mounted on the top wall of the detection fixture base 3031, the piston rod of the first air rod is vertically arranged, the fifth suction cup 3082 is fixedly mounted on the end of the piston rod of the first cylinder 3081, and the mouth of the fifth suction cup 3082 is arranged upward.

[0042] Four groups of pneumatic support components 309 are arranged at intervals on the detection fixture base 3031 along the length direction of the detection fixture base 3031, and one of the pneumatic support components 309 is fixedly installed at one side end of the detection fixture base 3031 where the pneumatic adsorption component 308 is located. Two groups of pneumatic support components 309 are arranged in a staggered interval with three support suction cups 307 of the pneumatic support component 309 close to the end of the detection fixture base 3031, and another pneumatic support component 309 is located between the second support suction cup 307 and the third support suction cup 307 at the other end of the detection fixture base 3031, and the four pneumatic support components 309 are arranged at intervals with any support suction cup 307 and any driving adsorption component.

[0043] Since the components, structures and installation methods of the four groups of pneumatic support assemblies 309 are the same, one group of pneumatic support assemblies 309 is used as an example for explanation: the pneumatic support assembly 309 includes a second cylinder 3091 and a second support plate 3092, the second cylinder 3091 is fixedly mounted on the top of the detection fixture base 3031, the piston rod of the second cylinder 3091 is vertically arranged, and the second support plate 3092 is vertically fixedly mounted on the upper end of the piston rod of the second cylinder 3091 by bolts. In order to reduce the damage to the snowboard caused by the contact between the second support plate 3092 and the snowboard, the upper end of the second support plate 3092 is made of nylon.

[0044] When the snowboard is installed on the detection fixture device 303, the seven sixth suction cups 3072 on the seven supporting suction cups 307 simultaneously work to absorb the snowboard, and then the three first cylinders 3081 and the four second cylinders 3091 are started, and respectively drive the three fifth suction cups 3082 and the four second support plates 3092 to move upward, until the three fifth suction cups 3082 absorb the snowboard, and the four second support plates 3092 contact and cooperate with the snowboard, and the installation is completed. At this time, the seven sixth suction cups 3072 and the three fifth suction cups 3082 have a downward force on the snowboard, and the four second support plates 3092 exert an upward force on the snowboard. The upward force and the downward force cooperate to stably fix the snowboard on the detection fixture device 303, and make the length direction of the snowboard installed on the detection fixture device 303 in the same direction as the length direction of the detection fixture base 3031, thereby improving the convenience of the visual instrument 3021 to detect the snowboard when it moves along the length direction of the detection fixture base 3031.

[0045] How it works

[0046] During operation, the snowboard is first horizontally and firmly installed on the detection fixture device 303, and the seven sixth suction cups 3072 on the seven supporting suction cups 307 simultaneously work to adsorb the snowboard. Then, the three first cylinders 3081 and the four second cylinders 3091 are started, and respectively drive the three fifth suction cups 3082 and the four second supporting plates 3092 to move upward, until the three fifth suction cups 3082 adsorb the snowboard, and the four second supporting plates 3092 are in contact with the snowboard, and the installation is completed; then, the second driving cylinder 305 is controlled to move through the solenoid valve 306, Until the visual instrument 3021 moves to the top of the snowboard, the visual instrument 3021 is started to detect the snowboard, and the drive motor 3041 is started at the same time. With the cooperation of the drive motor 3041, the gear 3042 and the rack 3043, the visual instrument 3021 is moved along the length direction of the detection fixture base 3031, thereby realizing the scanning of the entire snowboard. The scanned snowboard data is transmitted to the processing module of the visual instrument 3021, and the processing module calculates and analyzes the scanned snowboard data and determines whether the snowboard is a qualified product.
