Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printing detection, and particularly relates to a book printing quality detection device. BACKGROUND

[0002] After the production of a book printing product is completed, the printing quality of the book printing product needs to be strictly detected, including checking whether text and images exist defects such as misregistration, uneven ink color, dirty spots, scratches and the like. With the development of machine vision technology, automatic quality detection based on image recognition has gradually replaced traditional manual visual inspection and become a key means to improve detection efficiency and consistency.

[0003] However, when the automatic detection technology is applied to an actual production line, the existing equipment and process still face significant technical bottlenecks. For example, the positioning of the product to be detected is not uniform, which affects the recognition accuracy. That is, after the book (especially soft cover books, booklets and the like) is transported by the upstream process, the book is prone to posture skewing, front-back mispositioning or overlapping with each other before entering the detection station. This disordered state can cause the product to be detected to be out of the preset field of view or focal plane of the camera during image acquisition, thereby causing false detection and missed detection, which seriously restricts the accuracy and reliability of the detection system. In addition, the path adjustment is not flexible, and the site adaptability is poor. Therefore, there is a large room for improvement in the prior art. SUMMARY

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0027] Example 1, please refer to Figures 1-5 A book and periodical printing quality inspection device includes a main frame 1, on which a deflection frame mechanism 2 and a reciprocating vibration mechanism 3 are provided. An image recognition mechanism 4 is provided on the main frame 1. An initial conveying mechanism 5 and a deflection conveying mechanism 6 are provided on the deflection frame mechanism 2. A synchronous drive mechanism 7 is provided between the initial conveying mechanism 5 and the deflection conveying mechanism 6. The deflection conveying mechanism 6 is connected to a deflection drive mechanism 8. A plurality of positioning conveying plate mechanisms 9 are provided on the deflection frame mechanism 2. The reciprocating vibration mechanism 3 is used to drive the deflection frame mechanism 2 to vibrate.

The deflection drive mechanism 8 is used to drive the deflection conveying mechanism 6 to deflect and reposition. The positioning conveying plate mechanisms 9 are used to realize the conveying and positioning of the printed books and periodicals.

[0028] The deflection frame mechanism 2 includes a first rotating shaft 201 rotatably connected to the main frame platform 1. The first rotating shaft 201 is fixedly connected to the deflection frame 202. The deflection frame 202 is fixedly connected to two mounting arc plates 203. One of the mounting arc plates 203 is fixedly connected to a second rotating shaft 204. The second rotating shaft 204 is rotatably connected to the main frame platform 1. The mounting arc plate 203 is provided with a plurality of mounting slots 205. The main frame platform 1 is provided with a limiting baffle 206.

[0029] The image recognition mechanism 4 includes a light-shielding shell 401 fixed on the main frame 1, and an image recognition camera 402 is provided on the light-shielding shell 401.

[0030] Specifically, the image recognition camera 402 can be used to inspect the quality of printed books and periodicals.

[0031] The initial conveying mechanism 5 includes a first conveying wheel 501 rotatably connected to the deflection frame 202, the first conveying wheel 501 being driven to the first conveyor belt 502, the first conveyor belt 502 being driven to the second conveying wheel 503, and the second conveying wheel 503 being rotatably connected to the deflection frame 202.

[0032] The deflection conveying mechanism 6 includes a deflection cylinder 601 rotatably connected to the deflection frame 202, a deflection rod 602 fixedly connected to the deflection cylinder 601, a third conveying wheel 603 rotatably connected to the deflection rod 602, and a fourth conveying wheel 604 rotatably connected to the deflection cylinder 601. The shaft of the fourth conveying wheel 604 passes through the deflection cylinder 601. The third conveying wheel 603 and the fourth conveying wheel 604 are driven by a second conveyor belt 605. The synchronous drive mechanism 7 includes a motor bracket 701 fixed to the deflection frame 202, a second motor 702 fixedly connected to the motor bracket 701, a synchronous shaft 703 fixedly connected to the output shaft of the second motor 702, a first synchronous pulley 704 coaxially fixedly connected to the synchronous shaft 703, a first synchronous pulley 704 coaxially fixedly connected to the first synchronous pulley 704 and the fourth conveying wheel 604, a synchronous belt 705 driven by the first synchronous pulley 704, a second synchronous pulley 706 driven by the synchronous belt 705, and a second synchronous pulley 706 coaxially fixedly connected to the second conveying wheel 603. The deflection drive mechanism 8 includes a third motor 801 fixed on the deflection frame 202. The output shaft of the third motor 801 is fixedly connected to a first gear 802. The first gear 802 meshes with a second gear 803. The inner side of the second gear 803 is fixedly connected to a rotating cylinder 804. The rotating cylinder 804 and the deflection cylinder 601 are coaxially fixedly connected.

[0033] Specifically, when the second motor 702 is turned on, the output shaft of the second motor 702 rotates, which drives the synchronous shaft 703 to rotate. The rotation of the synchronous shaft 703 drives the first synchronous pulley 704 to rotate. The rotation of the first synchronous pulley 704 drives the fourth conveyor pulley 604 and the synchronous belt 705 to rotate. The rotation of the fourth conveyor pulley 604 drives the second conveyor belt 605 to rotate. The rotation of the synchronous belt 705 drives the second synchronous pulley 706 to rotate. The rotation of the second synchronous pulley 706 drives the second conveyor pulley 503 to rotate. The rotation of the second conveyor pulley 503 drives the first conveyor belt 502 to rotate, thereby moving the printed books placed on the first conveyor belt 502 and the second conveyor belt 605. Since the upper surface of the first conveyor belt 502 is lower than the upper surface of the deflection frame 202, the edge of the printed books can abut against the inner side of the deflection frame 202.

[0034] Additionally, when the third motor 801 is turned on, the output shaft of the third motor 801 rotates, which drives the first gear 802 to rotate. The rotation of the first gear 802 drives the second gear 803 to rotate, which drives the rotating drum 804 to rotate. The rotation of the rotating drum 804 drives the deflection drum 601, which drives the deflection rod 602 to rotate, thereby adjusting the position of the third conveyor wheel 603, and thus adjusting the end position of the second conveyor belt 605.

[0035] The positioning conveying plate mechanism 9 includes a conveying plate 901, with two symmetrically arranged side baffles 902 on the edge of the conveying plate 901, and two symmetrically arranged limiting rod mechanisms 903 on the side of the conveying plate 901. Each limiting rod mechanism 903 includes a rod groove 9031 on the conveying plate 901, with an elastic element 9032 fixedly connected to the conveying plate 901 within the rod groove 9031. A rod 9033 is fixedly connected to the end of the elastic element 9032, and is located within the rod groove 9031. The rod 9033 and the conveying plate 901 are slidably connected, and the cross-section of the rod 9033 is the same as that of the mounting slot 205.

[0036] Specifically, first, press the insert rod 9033 to compress the elastic element 9032. At this time, the insert rods 9033 on both sides pass through the mounting slot 205 to limit the conveyor plate 901. The side baffle 902 can limit the edge of the printed books and periodicals to prevent them from falling.

[0037] Example 2, see below. Figures 1-4In this embodiment of the invention, the reciprocating vibration mechanism 3 includes a vibration shaft seat 301 fixed on the main frame 1, a first motor 302 is provided on the vibration shaft seat 301, the output shaft of the first motor 302 is fixedly connected to a large roller 303, the large roller 303 and the vibration shaft seat 301 are rotatably connected, the large roller 303 is fixedly connected to a linear motor 304, the end of the linear motor 304 away from the large roller 303 is fixedly connected to a small roller 305, and the deflection frame 202 is fixedly connected to a vibration lever 306.

[0038] Specifically, when the deflection frame 202 is in a horizontal state, the surface of the large roller 303 is in contact with the deflection frame 202. At this time, the first motor 302 is turned on, and the output shaft of the first motor 302 rotates, which drives the large roller 303 to rotate, thereby driving the linear motor 304 and the small roller 305 to rotate, so as to make the deflection frame 202 vibrate back and forth, so as to achieve the edge positioning of the printed books and periodicals.

[0039] Additionally, activating the linear motor 304 can control the extension and retraction of the small roller 305, thereby adjusting the vibration amplitude to accommodate printed materials with different coefficients of friction and qualities.

[0040] In the implementation of this invention, the printed books and periodicals to be inspected are first placed in the initial conveying mechanism 5. At this time, the reciprocating vibration mechanism 3 is activated, which drives the deflection frame mechanism 2 to vibrate, thereby causing the printed books and periodicals to vibrate and move to the edge. Then, the synchronous drive mechanism 7 is activated, which drives the initial conveying mechanism 5 and the deflection conveying mechanism 6. When the initial conveying mechanism 5 carries the printed books and periodicals through the image recognition mechanism 4, the printing quality of the printed books and periodicals can be detected. Depending on the size and printing quality of the printed books and periodicals, the deflection drive mechanism 8 is activated, thereby causing the deflection conveying mechanism 6 to deflect and reposition, thus conveying the printed books and periodicals to the positioning conveying plate mechanism 9 at different positions.

[0041] This invention uses a reciprocating vibration mechanism 3 to drive the deflection frame mechanism 2 to vibrate, thereby achieving neat arrangement of printed books and periodicals along the edge, facilitating positioning and recognition by the image recognition mechanism 4, and also facilitating subsequent conveying and positioning. The synchronous drive mechanism 7 can drive the initial conveying mechanism 5 and the deflection conveying mechanism 6, thereby driving the printed books and periodicals to move continuously. The deflection drive mechanism 8 can drive the deflection conveying mechanism 6 to deflect and reposition. In conjunction with multiple positioning conveying plate mechanisms 9, the printed books and periodicals can be conveyed to designated positions, realizing sorting and conveying after printing quality inspection, and increasing the efficiency of printing quality inspection of books and periodicals.

Although the present invention 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.
