[0016] 1. The present application installs a conveying support roller below the detection base, and a shooting fill light for filling light in the shooting range is fixedly installed at the bottom of the shooting support plate. When in use, the shooting fill light is used to ensure the accuracy of shooting. At the same time, the conveying support roller is installed below the detection base to avoid the shadow problem caused by the existence of the robot.

DETAILED DESCRIPTION

[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0028] See also Figure 1-6 As shown, the appearance inspection device for die-cut parts includes an inspection base 1 for supporting the inspection of die-cut parts, a support top plate 2 is fixedly mounted on the inspection base 1 through a side mounting bracket 4, a visual inspection camera 3 is fixed on the side of the support top plate 2 facing the inspection base 1, and a conveying support roller 5 is arranged at the bottom of the inspection base 1, and the transfer of the die-cut parts is realized by the rotation of the conveying support roller 5. When in use, the die-cut parts are placed on the conveying support roller 5, and the conveying support roller 5 is used to realize the loading and unloading of the die-cut parts, and then the visual inspection camera 3 is used to take pictures of the die-cut parts on the conveying support roller 5, and the visual inspection of the die-cut parts is realized by visual recognition.

[0029] As a further embodiment of the present application, a flipping mechanism 6 is installed at the bottom of the detection base 1, and the flipping mechanism 6 is used to flip the sheet-like die-cut parts, and the other side of the die-cut parts is photographed for detection to ensure comprehensive detection of the die-cut parts.

[0030] Therefore, in the present application, by placing the conveying support roller 5 under the detection base 1, a device for lighting the die-cut parts is provided at the bottom of the detection base 1, so when in use, the shadow problem caused by the corresponding equipment on the machine tool can be avoided. At the same time, in the present application, the conveying support roller 5 is in a real-time rotation state, which can ensure the functions of automatic loading and unloading of the die-cut parts, and in the present application, no external equipment is required to clamp the die-cut parts, so the shadow problem can be avoided.

[0031] Therefore, a shooting support plate 7 for realizing shooting support is provided on the detection base 1, a shooting slot 8 for realizing shooting function is provided on the shooting support plate 7, and a shooting fill light 25 is fixed at the bottom of the shooting support plate 7, and a limit support frame 9 is symmetrically fixed on both sides of the detection base 1 to realize the movement limit of the conveying support roller 5. When in use, the die-cutting piece on the conveying support roller 5 is supplemented by the shooting fill light 25. At the same time, through the existence of the shooting slot 8, the visual detection camera 3 can shoot and realize the shooting of the die-cutting piece on the conveying support roller 5. In this process, by setting the shooting fill light 25 on the shooting support plate 7, the shooting fill light 25 can be used to directly shoot the die-cutting piece, and by lowering the height of the shooting fill light 25, the influence of the shadow can be reduced to ensure the accuracy of shooting. Even when the position of the die-cutting piece is slightly offset, the shadow influence caused by the external equipment can be avoided. At the same time, direct shooting on the conveying support roller 5 can ensure normal loading and unloading and avoid the space occupied by the external manipulator.

[0032] As a further embodiment of the present application, the flipping mechanism 6 includes a second pushing mechanism for lifting the die-cut piece and a first pushing mechanism for limiting the edge position of the die-cut piece. When in use, the first pushing mechanism and the second pushing mechanism are used to pass through between adjacent conveying support rollers 5, and the edge position of the die-cut piece is limited by the first pushing mechanism. At this time, the second pushing mechanism is used to move upward so that the second pushing mechanism pushes the die-cut piece until it is pushed to the highest point, and the first pushing mechanism continues to work so that the die-cut piece can achieve the function of flipping.

[0033] The first pushing mechanism includes a first pushing telescopic rod 11, wherein the first pushing telescopic rod 11 is placed horizontally and is used to control the output end to move horizontally. A first supporting telescopic rod 12 is fixedly installed at the output end of the first pushing telescopic rod 11. The first supporting telescopic rod 12 is used to control the output end to move longitudinally. The first supporting telescopic rod 12 is vertically arranged, and a first supporting top plate 13 is fixedly installed at the output end of the first supporting telescopic rod 12. A supporting push rod 15 is fixedly installed on the side of the first supporting top plate 13, wherein two groups of supporting push rods 15 are arranged, and the supporting push rods 15 can pass between two adjacent conveying support rollers 5. When in use, the first pushing telescopic rod 11 is used to control the first supporting telescopic rod 12 to move horizontally, thereby controlling the horizontal position of the supporting push rod 15, and the first supporting telescopic rod 12 is used to move longitudinally to control the longitudinal position of the supporting push rod 15, thereby facilitating the limiting support of the side of the die-cutting piece to realize the flipping function of the die-cutting piece.

[0034] The second pushing mechanism includes a second pushing telescopic rod 24, which is horizontally arranged and used to control the lateral movement of the output end. A second supporting telescopic rod 23 is fixedly installed at the output end of the second pushing telescopic rod 24, and a second supporting top plate 21 is fixedly installed at the output end of the second supporting telescopic rod 23. The side of the second supporting top plate 21 is fixedly installed with a first matching push rod 17 and a second matching push rod 20. When in use, the second pushing telescopic rod 24 is used to control the lateral movement of the second supporting telescopic rod 23, and the start of the second supporting telescopic rod 23 is used to control the height of the first matching push rod 17 and the second matching push rod 20, so as to facilitate the bottom of the die-cutting piece to be pushed upwards, so as to facilitate the flipping function of the die-cutting piece.

[0035] In the above technical solution, in order to realize the flipping function of the die-cut piece, the first pushing telescopic rod 11 and the second pushing telescopic rod 24 are firstly started, so that the support push rod 15, the first matching push rod 17 and the second matching push rod 20 are respectively located at the bottom of the die-cut piece, and then the first supporting telescopic rod 12 is started to make the supporting push rod 15 move upward, and at the same time, the first pushing telescopic rod 11 is started until the supporting push rod 15 passes through the conveying support roller 5 and acts on the edge of the die-cut piece; then, when in use, the second supporting telescopic rod 23 and the second pushing telescopic rod 24 are used to support the bottom of the die-cut piece upward, and at the same time, the first pushing telescopic rod 11 controls the supporting push rod 15 to move upward. The rod 15 moves laterally, gradually making the die-cut piece stand up vertically. At this time, the first mating push rod 17 and the second mating push rod 20 move laterally, completing the inclination angle of the die-cut piece to be greater than ninety degrees. Then the first mating push rod 17 and the second mating push rod 20 are moved sideways and downward, so that the first mating push rod 17 and the second mating push rod 20 are moved out from the adjacent conveying support roller 5. The continuous action of the first pushing telescopic rod 11 is utilized to enable the die-cut piece to realize the flipping function. After the flipping is completed, the height of the supporting push rod 15 is controlled by the first supporting telescopic rod 12, and the supporting push rod 15 is moved out from the adjacent conveying support roller 5, thereby realizing the automatic flipping function of the die-cut piece.

[0036] As a further embodiment of the present application, in order to avoid interference between the die-cutting piece and the supporting push rod 15, the first cooperating push rod 17 and the second cooperating push rod 20 respectively, the supporting push rod 15, the first cooperating push rod 17 and the second cooperating push rod 20 are L-shaped, and the supporting push rod 15, the first cooperating push rod 17 and the second cooperating push rod 20 are inverted L-shaped, which is convenient for flipping the die-cutting piece.

[0037] Furthermore, a first bottom pressure nozzle 10 is fixed at the bottom of the side of the first support top plate 13. A first connecting column 14 is fixedly installed above the first support top plate 13, and a first top pressure nozzle 16 is fixed at the top of the first connecting column 14. When in use, the first bottom pressure nozzle 10 is used to perform jet cleaning on the rotating conveying support roller 5, and a certain pressure of gas is sprayed to remove its impurities. Then, a certain pressure of gas is sprayed at the first top pressure nozzle 16, so that the first top pressure nozzle 16 can perform air blowing cleaning on the die-cutting piece above the conveying support roller 5. In this process, the die-cutting piece is very easy to adhere to debris when cutting, so in the above technical solution, the adhered debris can be sprayed away by the action of the first bottom pressure nozzle 10 and the first top pressure nozzle 16.

[0038] A second bottom pressure nozzle 22 is fixed on the side of the second supporting top plate 21, and a second connecting column 19 is fixedly installed on the top of the second supporting top plate 21, wherein a second top pressure nozzle 18 is fixed on the top of the second connecting column 19. When in use, the second bottom pressure nozzle 22 is used to spray and clean the bottom of the die-cut part. At this time, since the height of the second top pressure nozzle 18 is higher than the height of the first matching push rod 17, the second top pressure nozzle 18 can spray the top of the die-cut part to avoid more impurities adhering to it and affecting the shooting effect.

[0039] Specifically, the transmission support roller 5 is rotatably mounted on the frame, and the rotation of the transmission support roller 5 is realized by the power device and the transmission chassis. When the transmission support roller 5 is always in motion, automatic loading and unloading of the die-cut parts can be realized.

[0040] When the present invention is in use, by placing the conveying support roller 5 below the detection base 1, a device for lighting the die-cut piece is provided at the bottom of the detection base 1, so when in use, the shadow problem caused by the corresponding equipment on the machine tool can be avoided. At the same time, in the present application, the conveying support roller 5 is in a real-time rotating state, which can ensure the automatic loading and unloading functions of the die-cut piece, and in the present application, no external equipment is required to clamp the die-cut piece, so the shadow problem can be avoided;

[0041] In order to realize the flipping function of the die-cut piece, the first push telescopic rod 11 and the second push telescopic rod 24 are firstly started, so that the support push rod 15, the first matching push rod 17 and the second matching push rod 20 are respectively located at the bottom of the die-cut piece, and then the first support telescopic rod 12 is started to make the support push rod 15 move upward, and at the same time, the first push telescopic rod 11 is started until the support push rod 15 passes through the conveying support roller 5 and acts on the edge of the die-cut piece; then, when in use, the second support telescopic rod 23 and the second push telescopic rod 24 are used to support the bottom of the die-cut piece upward, and at the same time, the first push telescopic rod 11 controls the support push rod 15 to move horizontally. The die-cut piece is gradually erected vertically, and the first mating push rod 17 and the second mating push rod 20 are moved horizontally at this time, so that the inclination angle of the die-cut piece is greater than ninety degrees, and then the first mating push rod 17 and the second mating push rod 20 are moved sideways and downward, so that the first mating push rod 17 and the second mating push rod 20 are moved out of the adjacent conveying support roller 5, and the die-cut piece can be turned over by the continuous action of the first pushing telescopic rod 11, and after the turning over is completed, the height of the supporting push rod 15 is controlled by the first supporting telescopic rod 12, and the supporting push rod 15 is moved out of the adjacent conveying support roller 5, so that the automatic turning over function of the die-cut piece can be realized;

[0042] The first bottom pressure nozzle 10 is used to perform jet cleaning on the rotating conveying support roller 5, and gas at a certain pressure is sprayed to remove its impurities. Then, gas at a certain pressure is sprayed from the first top pressure nozzle 16, so that the first top pressure nozzle 16 can blow and clean the die-cut part above the conveying support roller 5; at the same time, the second bottom pressure nozzle 22 is used to perform jet cleaning on the bottom of the die-cut part. At this time, since the height of the second top pressure nozzle 18 is higher than the height of the first matching push rod 17, the second top pressure nozzle 18 can perform jet operation on the top of the die-cut part to prevent it from being adhered to a large number of impurities and affecting its shooting effect.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
