Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] like Figure 1 and Figure 2 The screen printing inspection device shown includes a card issuing mechanism 100, a pre-acceleration mechanism 200, an inspection mechanism 300, a transmission mechanism 400, a rejection mechanism 500, a good product transmission mechanism 600, and a vertical receiving mechanism 700 arranged sequentially along the product 800 travel path. It also includes a controller for controlling the operation of the entire screen printing inspection device.

[0048] like Figures 6 to 8As shown, the testing mechanism 300 includes a testing frame, on which a light source group and a camera group are provided. The camera group is positioned above the light source group. The light source group includes a first light source 301, a second light source 302, and a third light source 303 arranged sequentially along the travel path of the product 800. The first light source 301 and the third light source 303 are positioned above the product 800, and the second light source 302 is positioned below the product 800. The camera group includes a first camera 304 that cooperates with the first light source 301, a second camera 305 that cooperates with the second light source 302, and a third camera 306 that cooperates with the third light source 303. A light shield 307 is provided above the second light source 302 and is positioned above the product 800. The first light source 301 has a first testing area 308 for easy shooting by the first light source 301, the light shield 307 has a second testing area 309 for easy shooting by the second camera 305, and a third testing area 310 for easy shooting by the third camera 306 is provided on one side of the third light source 303. The light shield 307 prevents excess light from the second light source 302 from entering the second camera 305.

[0049] The testing frame is equipped with a camera bracket 312 for mounting the camera assembly, and the testing frame is also equipped with a testing pressure roller 311 for pressing down the product 800.

[0050] The first light source 301 is a dome light source, and the second light source 302 and the third light source 303 are both strip light sources; the first camera 304, the second camera 305 and the third camera 306 are all line scan cameras.

[0051] The first camera 304 and the first light source 301 work together to detect defects such as mixed colors, mixed products, and missing colors. The second camera 305 and the second light source 302 work together, and the third camera 306 and the third light source 303 work together. All of these can detect defects such as: misregistration (double corners / rough edges / large and small edges, etc.), screen blockage (keyholes, missing parts, etc.), screen (excess gold, dirty spots), dirt, poor hot stamping, streaking, rough edges, color difference, and scratches.

[0052] like Figure 3 and Figure 4 As shown, the card issuing mechanism 100 includes a card issuing frame and a material carrier plate 101. The card issuing frame is provided with a transfer component 103, which is located above the material carrier plate 101. A suction cup component 104 is installed at the output end of the transfer component 103. A baffle 102 is installed on the material carrier plate 101, which is positioned relative to the suction cup component 104. The card issuing frame is provided with a lifting component that drives the material carrier plate 101 to rise and fall.

[0053] A first crossbeam 105 is installed on the card issuing machine frame. A set of guide rod mounting seats is provided on the first crossbeam 105, and guide rods 106 are installed on the guide rod mounting seats. A long slot is provided on the material carrier plate 101, through which two guide rods 106 pass, and the two guide rods 106 are located on both sides of the product 800. The two guide rods 106 have two functions: firstly, the distance between the two guide rods 106 is adjustable to accommodate different models of product 800; secondly, the guide rods 106 can limit the position of the product 800 on the material carrier plate 101, and together with the baffle 102, prevent the product 800 from shifting during the card issuing process.

[0054] like Figure 5 As shown, the second light source 302 is installed between the pre-acceleration mechanism 200 and the transmission mechanism 400. The conveyor belts of the pre-acceleration mechanism 200 and the transmission mechanism 400 are suction belts. A pressure roller assembly 201 is installed at the feed end of the pre-acceleration mechanism 200 and at the discharge end of the transmission mechanism 400. The pre-acceleration mechanism 200 includes a first anti-warping pressure roller 202 and a second anti-warping pressure roller 203 installed above the conveyor belt. The second anti-warping pressure roller 203 is located near the side of the frame of the pre-acceleration mechanism 200.

[0055] The card issuing mechanism 100 operates at a lower speed than the transmission mechanism 400; therefore, a pre-acceleration mechanism 200 is provided to increase the transmission speed of the product 800, working in conjunction with the detection mechanism 300 and the transmission mechanism 400. The pressure roller assembly 201 increases the friction between the product 800 and the suction belt, which prevents the product 800 from moving during transmission. Small-sized products use a first anti-warping pressure roller 202, while large-sized products use a second anti-warping pressure roller 203, preventing product warping and ensuring the products are flat during inspection, thus improving inspection efficiency. Both the first and second anti-warping pressure rollers 202 and 203 are adjustable to accommodate products of various sizes.

[0056] like Figures 9 to 11 As shown, the rejection mechanism 500 includes a rejection flap 501 installed between the conveying mechanism 400 and the good product conveying mechanism 600. Below the good product conveying mechanism 600, there is a waste collection frame 503 for collecting waste. A rejection guide plate 502 is installed at the feeding end of the waste frame 503. Both the rejection guide plate 502 and the waste frame 503 are inclined and have the same inclination angle. The rejection flap 501 is equipped with a flipping shaft 504, and a rejection drive mechanism is connected to the flipping shaft 504.

[0057] The good product conveying mechanism 600 includes a good product conveying frame 603, on which an inclined support plate 601 and multiple conveyor belts 602 are mounted, with the multiple conveyor belts 602 laid along the upper surface of the support plate 601; a good product pressure roller assembly 604 is mounted on the good product conveying frame 603, with the pressure roller of the good product pressure roller assembly 604 abutting against the conveyor belts 602; an opening 605 is provided on the side plate of the good product conveying frame 603 to facilitate the removal of the waste frame 503. After the waste frame 503 is full, it is removed and replaced through the opening 605.

[0058] The support plate 601 has an angle of 5° with the horizontal plane, and the output end is higher than the input end, so that the support plate 601 forms a climbing structure, which provides a certain parabolic angle for subsequent vertical material collection. Because the product 800 is large in size, if it is projected horizontally, the tail of the product 800 will droop, which is not conducive to the neat collection of the product 800.

[0059] like Figure 12 As shown, the vertical receiving mechanism 700 includes a receiving frame and a receiving table 701. A second crossbeam 704 is installed on the receiving frame above the receiving table 701. Two tapping bases are installed on the second crossbeam 704. A cylinder is installed at the bottom of the tapping base, and a tapping plate 703 is installed at the output end of the cylinder to tap the product 800 neatly. A rear baffle 702 is installed on the receiving table 701 to prevent the product 800 from rushing out of the receiving table 701. The receiving frame is equipped with a lifting assembly for lifting the receiving table 701.

[0060] like Figure 13 and Figure 14 As shown, the lifting mechanism includes a motor 903 and two sets of lifting components. The motor 903 drives one set of lifting components to work. Each lifting component includes a belt 902 and a slide rail assembly. The belt 902 is wound around and connected to a drive wheel and a driving wheel. The drive wheels of the two sets of lifting components are connected by a synchronous shaft 901. The slide rail assembly includes a slidingly connected rail 904 and a slider 905. The slider 905 is connected to the belt 902. The rotation of the belt 902 drives the slider 905 to rise and fall. The lifting mechanism also includes a limiting mechanism, which includes a limiting insert 907 and two limit sensors 906 distributed vertically. The two limit sensors 906 are respectively installed on the card issuing frame and the receiving frame, and the limiting insert 907 is installed on the material carrier plate 101 and the receiving table 701.

[0061] The working process of the lifting mechanism 900 is as follows: the motor 903 drives the drive wheel of the left lifting component to rotate, which drives the belt 902 to rotate, thereby causing the slider 905 to move up and down along the track 904, thereby driving the material carrier plate 101 or the receiving platform 701 to move up and down; a limit mechanism is provided, and the limit insert 907 cooperates with two limit sensors 906 respectively to prevent the material carrier plate 101 or the receiving platform 701 from exceeding the limit during the upward or downward movement.

[0062] The specific working process of this screen-printed product inspection device is as follows:

[0063] Step S1: Card issuance. The carrier plate 101 is manually loaded, and then the lifting mechanism 900 drives the carrier plate 101 to move up to the target position. The suction cup assembly 104 adsorbs the first product 800. The transfer assembly 103 works to drive the suction cup assembly 104 to move forward, separating the products 800 one by one and sending them to the pre-acceleration mechanism 200. While the suction cup assembly 104 transfers the products 800, the lifting mechanism 900 simultaneously drives the carrier plate 101 to move up.

[0064] Step S2, Pre-acceleration: The suction belt of the pre-acceleration mechanism 200 conveys the product 800 to increase the transmission speed of the product 800.

[0065] Step S3: Inspection. The product 800 passes through the first light source 301, the second light source 302, and the third light source 303 in sequence. The first light source 301 and the third light source 303 provide light to the upper surface of the product 800, and the second light source 302 provides light to the lower surface of the product 800. The first camera 304, the second camera 305, and the third camera 306 perform visual inspection on the product 800 through the first inspection area 308, the second inspection area 309, and the third inspection area 310, respectively, and send the inspection results to the controller.

[0066] Step S4, Transmission: The transmission mechanism 400 conveys the inspected products. The suction belt of the transmission mechanism 400 ensures that the products are flat and do not shift during the transmission process.

[0067] Step S5: Rejection. Based on the detection results of the detection mechanism 300, if the product is good, the rejection flap 501 does not flip and remains horizontal to ensure that the good product enters the good product conveying mechanism 600; if the product is bad, the rejection drive mechanism works, driving the flipping shaft 504 to rotate, which in turn causes the rejection flap 501 to flip upward, forming a bad product channel between the rejection flap 501 and the conveying mechanism 400. The bad product enters the waste box 503 after passing through the bad product channel and the rejection guide plate 502.

[0068] Step S6: Good product conveying. Multiple conveyor belts 602 of the good product conveying mechanism 600 convey the product 800, and the good product pressure roller assembly 604 improves the flatness of the product 800.

[0069] Step S7: Vertical material collection. Product 800 enters the material collection table 701. The patting board 703 pats both sides of product 800 to make product 800 neatly collected. At the same time, the lifting component drives the material collection table 701 to descend, completing the collection of good products.

[0070] In summary, this utility model has a simple structure and reasonable design. The card issuing mechanism 100 separates the printed materials one by one, the pre-acceleration mechanism 200 transports them, the detection mechanism 300 takes pictures, and the defective products are rejected by the rejection mechanism 500. Good products are transported to the vertical receiving mechanism 700 by the good product transport mechanism 600. The detection accuracy is high and the detection speed is fast. The equipment operates smoothly and has a high degree of mechanization. It saves labor and improves the quality of products.

[0071] The above description is only a specific embodiment of the present utility model. Various examples and illustrations do not constitute a limitation on the substantive content of the present utility model. Those skilled in the art can make modifications or variations to the above-described specific embodiments after reading the description without departing from the substance and scope of the utility model.
