DETAILED DESCRIPTION

[0059] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0060] The core of the present application is to provide a detection device, which can realize automatic scanning of the two-dimensional code on the mobile phone screen by setting a conveying device, a detection device and a control device.

[0061] Another core of the present application is to provide a production system comprising the above detection device.

[0062] Please refer to Figures 1-12 .

[0063] The specific embodiment discloses a detection device, which comprises a conveying device 1, a detection device 6 and a control device, wherein the conveying device 1 is used for conveying a product 34 to be read to a code reading station 103 or conveying a detected product 34 to a discharging station 105; the detection device 6 comprises a photographing member 19 and a light source 18, the photographing member 19 is used for acquiring image information of an identification code 341 of the product 34 to be read of the code reading station 103, and the light source 18 is used for illuminating the photographing member 19; the control device is used for receiving the image information photographed by the photographing member 19 and identifying the image information; the conveying device 1 and the detection device 6 are connected with the control device, and the control device is used for controlling the actions of the conveying device 1 and the detection device 6.

[0064] It should be noted that the detection device provided in this specific embodiment can be used to identify the QR code on the transparent film. The identification code 341 can also be a barcode or other form of code, and can also be used to identify the identification code 341 of other electronic devices. The specific method is determined according to the actual situation, and will not be elaborated here.

[0065] In actual use, firstly, the product 34 to be coded needs to be placed on the conveying device 1. The conveying device 1 transports the product 34 to the coding station 103. The light source 18 of the detection device 6 shines on the product 34 at the coding station 103, and the imaging device 19 acquires the image information of the identification code 341 of the product 34 at the coding station 103, and transmits the image information to the control device. The control device identifies the identification code 341 of the product 34 based on the image information. The detected product 34 is then output by the discharge roller 4.

[0066] The testing equipment provided in this specific embodiment can automatically identify the identification code 341 of product 34. During the identification process, no manual operation is required, effectively improving identification efficiency. Furthermore, it avoids dust accumulation caused by manual operation, which is beneficial for improving product quality. In addition, continuous testing of product 34 can be achieved through control of the control device, further improving testing efficiency.

[0067] On the other hand, when the product 34 to be inspected is the identification code 341 in the transparent film on the LCD screen, the product 34 can be placed in the tray 31, and the specific shape of the tray 31 can be set to... Figure 3 , Figure 4 As shown in the diagram, the same tray 31 can hold multiple products 34 or only one product 34, depending on the actual situation. Furthermore, to improve the efficiency, accuracy, and robustness of barcode reading, the surface of the tray 31 used to hold the product 34 can be set to black or a dark color, giving the transparent label a mirror effect and increasing its reflectivity. At the same time, the identification code 341 is generally a black, non-reflective coating, which creates a large contrast between light and dark with the background, making the image captured by the camera clear and easy for the algorithm to recognize. This further reduces the influence of external light and improves the robustness of visual recognition.

[0068] In addition, the light source 18 needs to be set as a surface light source 18 with a central opening. The surface light source 18 generates uniform parallel vertical downward light, which is reflected directly back to the photographic object 19 after being reflected by the identification code 341, reducing reflections in other directions, making the image of the photographic object 19 uniform in brightness and darkness, and improving the image quality.

[0069] When multiple products 34 are arranged in the same tray 31, the combination of the light source 18 and the shooting member 19 should be arranged in a manner that the shooting range of the shooting member 19 can cover the whole tray 31. As shown in Figure 3 、 Figure 4 two rows and two columns, which has the advantages of reading multiple identification codes 341 at one time and avoiding the influence of the central dark part of the opening surface light source 18 on the imaging of the shooting member 19.

[0070] In an embodiment, the detection device further comprises a protective cover 2 outside the cover detection apparatus 6, and the protective cover 2 is provided with air supply filtering apparatus, and the external gas enters the protective cover 2 after being filtered by the air supply filtering apparatus.

[0071] The specific structure of the protective cover 2 can be the structure as shown in Figure 1 , and the air supply filtering apparatus is arranged at the top of the protective cover 2. In actual use, the protective cover 2 itself can avoid the influence of external impurities and dust on the product 34 and the detection device, and the arrangement of the air supply filtering apparatus can make the gas enter the protective cover 2 after being filtered, thereby further improving the dustproof effect.

[0072] In an embodiment, the detection device further comprises a first positioning mechanism 5, a second positioning mechanism 7 and a first transfer mechanism 10. The first positioning mechanism 5 is arranged at the code reading station 103 of the conveying device 1, and is used for positioning the product 34 to be read; the second positioning mechanism 7 is arranged at the stacking station 104 of the conveying device 1, and the stacking station 104 is used for stacking the detected product 34; the first transfer mechanism 10 has a first moving end which can be lifted and moved along the conveying direction of the conveying device 1, and the first moving end is provided with a first jig 13 which can be moved between a first position and a second position; the first jig 13 can obtain the product 34 detected by the code reading station 103 when it is located at the first position, and the first jig 13 can place the obtained product 34 to the stacking station 104 when it is located at the second position.

[0073] It should be noted that the first positioning mechanism 5 and the second positioning mechanism 7 can be provided with the same structure, specifically, the first positioning mechanism 5 and the second positioning mechanism 7 can each include at least two first positioning plates 33, a first clamping power element 30, at least two second positioning plates and a second clamping power element, wherein the at least two first positioning plates 33 are relatively close or far away along a first direction to clamp or release the product 34 in the first direction; the first direction is perpendicular to the conveying direction of the conveying device 1 and parallel to the plane for carrying the product 34 in the conveying device 1; the first clamping power element 30 is installed on one side of the conveying device 1, and the clamping power element is used to drive the first positioning plate 33 to be relatively close or far away; the at least two second positioning plates are relatively close or far away along a second direction to clamp or release the product 34 in the second direction; the second direction is along the conveying direction of the conveying device 1. The second clamping power element is installed on the first positioning plate 33, and the second clamping power element is used to drive the second positioning plate to be relatively close or far away.

[0074] In actual use, when the product 34 is conveyed to the code reading station 103, the first clamping power element 30 controls the first positioning plate 33 to clamp the product 34 along the first direction, and the second clamping power element controls the second positioning plate to clamp the product 34 along the second direction, so as to position the product 34; when the product 34 is placed on the tray 31, the first clamping power element 30 controls the first positioning plate 33 to clamp the stacked tray 31 along the first direction, and the second clamping power element controls the second positioning plate to clamp the stacked tray 31 along the second direction, so as to position the stacked tray 31.

[0075] It should be noted that when the product 34 is stacked on the conveying device 1, the height of the product 34 located at the topmost layer is higher, and the height of the product 34 located at the bottom is lower. In order to adapt to the identification of the identification code 341 of the product 34 at different height positions, the detection device 6 can be provided with a lifting structure, and the lifting structure drives the shooting member 19 and the light source 18 to lift, so as to adapt to the product 34 at different height positions or the tray 31 at different height positions.

[0076] After the identification code 341 of the product 34 is identified, the first jig 13 of the first transfer mechanism 10 moves to the first position to obtain the product 34 detected by the code reading station 103, and drives the product 34 to move to the second position, and places the product 34 or the tray 31 containing the product 34 to the stacking station 104. When the product 34 or the tray 31 containing the product 34 is stacked to a proper height at the stacking station 104, the first clamping power member 30 controls the first positioning plate 33 to clamp the product 34 or the tray 31 containing the product 34 at the stacking station 104 in the first direction, and the second clamping power member controls the second positioning plate to clamp the product 34 or the tray 31 containing the product 34 in the second direction, so as to position the product 34 or the tray 31 containing the product 34.

[0077] As shown in Figure 6 The first transfer mechanism 10 can include the first jig 13, the first lifting module 14, the first moving module 15, and the first mounting base 16. The first mounting base 16 is arranged on one side of the conveying device 1. Specifically, the first mounting base 16 can be fixedly arranged on the ground, or fixedly arranged on the rack 3 at the lower part of the conveying device 1, or fixedly arranged on the outer frame of the conveying device 1. The first moving module 15 has a first sliding member movable along the conveying direction of the conveying device 1. The first sliding member is connected with the first lifting module 14. The first lifting module 14 is provided with a first moving end. The first moving end is provided with the first jig 13. The first jig 13 includes a first support and a first suction cup. The first support is located above the conveying device 1. The first suction cup is arranged on the side of the first support facing the conveying device 1. The first suction cup is used to suck the product 34 detected by the code reading station 103, and transfer the sucked product 34 to the stacking station 104.

[0078] The first jig 13 in the embodiment can suck the product 34 or the tray 31 containing the product 34 by the suction cup, so as to avoid damaging the surface of the product 34, and avoid bringing dust to the product 34, and further improve the product quality.

[0079] On the basis of the above embodiment, the detection device can further include a second transfer mechanism 8. The second transfer mechanism 8 has a second moving end which is liftable and movable along the conveying direction of the conveying device 1. The second moving end is arranged on the second jig 23 movable between the third position and the fourth position. When the second jig 23 is located at the third position, the second jig 23 can obtain the product 34 to be read at the uppermost layer of the code reading station 103. When the second jig 23 is located at the fourth position, the image information of the product 34 on the second jig 23 can be obtained by the photographing member 19.

[0080] As shown in Figure 7As shown, the second transfer mechanism 8 comprises a second mounting base, a second jig 23, a second lifting module 21, and a second moving module 22. The second mounting base is arranged on one side of the conveying device 1. Specifically, the second mounting base can be fixed to the ground, or fixed to the rack 3 at the lower part of the conveying device 1, or fixed to the outer frame of the conveying device 1.

The second suction cup is used to suck the product 34 to be read in the reading code station 103. The sucked product 34 is transferred to the position for detection by the detection device 6.

[0081] In actual use, when the products 34 in the stacked state or the trays 31 containing the products 34 in the stacked state are located in the reading code station 103, the second jig 23 can suck the product 34 to be read in the reading code station 103, and transfer the product 34 to the position for detection by the detection device 6. The identification code 341 of the product 34 in the detection position is identified by the shooting member 19. After the identification is completed, the first jig 13 of the first transfer mechanism 10 acquires the product 34 or the tray 31 containing the product 34 which has been identified by the second jig 23. The second jig 23 releases the product 34 or the tray 31 containing the product 34 which has been identified. The first transfer mechanism 10 drives the product 34 or the tray 31 containing the product 34 which has been identified to be transferred to the stacking station 104.

[0082] It should be noted that, in actual use, in order to enable the first transfer mechanism 10 and the second transfer mechanism 8 to work synchronously, the transfer paths of the first transfer mechanism 10 and the second transfer mechanism 8 can be arranged at different heights and offset. In addition, in order to enable the first jig 13 to smoothly transfer the product 34 or the tray 31 containing the product 34 after acquiring the product 34 or the tray 31 containing the product 34 which has been identified by the second jig 23, the first jig 13 and the second jig 23 can suck different positions of the product 34 or the tray 31, so as to complete the avoidance of the product 34 or the tray 31 and the second jig 23.
