Detailed implementation manners

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0041] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0042] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality of" is two or more unless otherwise specifically defined.

[0043] Currently, most labeling devices use a single suction head assembly to pick up labels. If different labels need to be attached to the same product simultaneously or there are multiple products in the same fixture, step-by-step operations are required. This operation method is inefficient and seriously affects the labeling efficiency of products. Manual labeling, on the other hand, consumes a lot of labor and has high requirements for labeling accuracy. It may lead to unsatisfactory labeling effects, such as crooked labels, label detachment, and low consistency of finished products due to unstable work quality of people.

[0044] Please refer to Figures 9 to 10 , considering the above problems, the present application provides a labeling suction mechanism, which includes:

[0045] A support assembly 220, including a support frame 221, a driving support member 222, and a limiting support member 223. The driving support member 222 and the limiting support member 223 are spaced apart and arranged on the support frame 221;

[0046] A plurality of suction head assemblies 230 are arranged on the limiting support member 223, and the suction head assemblies 230 are configured to move along a first direction under the limiting action of the limiting support member 223;

[0047] A plurality of driving assemblies 240 are arranged on the driving support member 222. The plurality of suction head assemblies 230 are respectively connected to the plurality of driving assemblies 240 in one-to-one correspondence to respectively drive the plurality of suction head assemblies 230 to move independently along the first direction.

[0048] Currently, most labeling devices use a single adsorption head assembly 230 to absorb the label 51. If different labels 51 need to be attached to the same product 5 at the same time or there are multiple products 5 in the same fixture, a step-by-step operation is required. This operation method is inefficient and seriously affects the labeling efficiency of the product 5. Manual labeling consumes manpower and requires high labeling accuracy. The unstable work quality of humans may lead to unsatisfactory labeling results, labels 51 being crooked or falling off, and low consistency of finished products.

[0049] In this embodiment, a driving support 222 and a limiting support 223 are provided on the support assembly 220, which can respectively realize the support of multiple adsorption head assemblies 230 and multiple driving assemblies 240. The adsorption head assembly 230 can move along the first direction under the limiting action of the limiting support 223, thereby realizing the precise movement of the label 51 in a small range, accurately absorbing the label 51 and realizing the pasting of the label 51. It can be seen that the local direction here refers to the moving direction of the adsorption head assembly 230 when absorbing and attaching the label 51. Multiple adsorption head assemblies 230 are respectively connected to multiple driving assemblies 240 in a one-to-one correspondence to drive the multiple adsorption head assemblies 230 to move independently along the first direction, so that each adsorption head assembly 230 can move up and down independently, that is, each adsorption head assembly 230 can independently adsorb a label 51, and multiple adsorption head assemblies 230 can be used to adsorb multiple different labels 51, and attach multiple different labels 51 to a product 5 at the same time, so as to attach different labels 51 to a product 5; or multiple adsorption head assemblies 230 can adsorb multiple identical labels 51 at the same time, and attach each label 51 to a product 5 respectively, so as to realize simultaneous labeling of multiple products 5, which can improve labeling efficiency.

[0050] See also Figure 11 and Figure 12 In some embodiments of the present application, the limiting support 223 is provided with a first through hole 2231 along the first direction, the adsorption head assembly 230 is inserted into the first through hole 2231, and the adsorption head assembly 230 is slidably matched with the limiting support 223, so that the adsorption head assembly 230 can move along the first direction under the limiting action of the limiting support 223.

[0051] The main function of the position-limiting support 223 is to limit the adsorption head assembly 230 in the first direction, thereby ensuring that the adsorption head assembly 230 does not shake during movement and ensuring the stability of the adsorption and attachment of the label 51. The position-limiting support 223 can adopt a structure such as a guide hole or a guide groove. In this embodiment, the position-limiting support 223 is provided with a first through hole 2231 along the first direction, and the adsorption head assembly 230 is inserted into the first through hole 2231. The first through hole 2231 can serve as a guide hole, allowing the adsorption head assembly 230 to move stably along the first direction.

[0052] Please refer to Figure 10 and Figure 13 In some embodiments of the present application, the first through hole 2231 is a T-shaped hole having three groove structures, and the number of the suction head assemblies 230 is three. The three suction head assemblies 230 are respectively arranged in the three groove structures of the first through hole 2231.

[0053] The number of the suction head assemblies 230 can be designed according to requirements, such as two, three, four, five, etc. In this embodiment, the number of the suction head assemblies 230 is three. For the three suction head assemblies 230, if they are directly arranged in a straight line, the distance may be too close and it may be difficult to connect to the driving assembly 240. In this embodiment, the first through hole 2231 that provides a limiting function for the suction head assemblies 230 is a T-shaped hole. The T-shaped hole can be divided into three grooves. The three suction head assemblies 230 are respectively arranged in the three groove structures of the first through hole 2231, so that the distance between the suction head assemblies 230 can be increased without increasing the lateral width, which is beneficial to connecting the driving assembly 240 and is also more conducive to independent control respectively. In addition, each suction head assembly 230 can contact three surfaces of the T-shaped hole, so that the limiting function of the first through hole 2231 on the suction head assembly 230 can be ensured.

[0054] Please refer to Figure 14 In some embodiments of the present application, a limiting boss 2304 is provided on the side surface of the suction head assembly 230. The limiting boss 2304 is configured to be abutted against the edge of the first through hole 2231 to limit the moving distance of the suction head assembly 230 in the first direction.

[0055] In this embodiment, a limiting boss 2304 is provided on the side surface of the suction head assembly 230. When the suction head assembly 230 moves to make the limiting boss 2304 abut against the edge of the first through hole 2231, it cannot move any further, so as to achieve the purpose of limiting the moving distance of the suction head assembly 230 in the first direction. By limiting the moving distance of the suction head assembly 230 in the first direction, the consistency of the adsorption and attachment moving distance of the suction head assembly 230 each time can be ensured, and the situation that the label 51 is not tightly attached and falls off or is pressed too tightly to damage the product 5 due to inconsistent distances can be avoided. The limiting boss 2304 can be provided on only one side surface of the suction head assembly 230, or on multiple side surfaces. For the case where the three suction head assemblies 230 are arranged in the T-shaped hole, the limiting boss 2304 can be provided on the non-adjacent side surfaces of the suction head assembly 230, and not provided on the adjacent side surfaces to avoid the limiting boss 2304 interfering with the movement of the suction head assembly 230.

[0056] Please refer to Figure 12, in some embodiments of the present application, a first positioning hole 2214 and a second positioning hole 2215 are provided on the support frame 221. The driving support member 222 has a first boss 2223, and the limiting support member 223 has a second boss 2232. The second boss 2232 is positioned in the second positioning hole 2215, and the second boss 2232 is positioned in the second positioning hole 2215.

[0057] The limiting support member 223 and the driving support member 222 can be connected to the support frame 221 by means of welding, bolt connection, etc. To ensure the accuracy of the connection, in this embodiment, the driving support member 222 has a first boss 2223, and the limiting support member 223 has a second boss 2232. The first boss 2223 is arranged in the first positioning hole 2214, and the second boss 2232 is arranged in the second positioning hole 2215. Thus, through the interaction of the positioning holes and the bosses, the accuracy of the positions where the limiting support member 223 and the driving support member 222 are connected to the support frame 221 can be ensured.

[0058] Please refer to Figure 14 , in some embodiments of the present application, the suction head assembly 230 includes:

[0059] A suction disc 2301 having a suction surface for sucking the label 51, and suction holes are provided on the suction surface;

[0060] A suction rod 2302 connected to the suction disc 2301, and an air flow hole is provided in the suction rod 2302, and the air flow hole is communicated with the suction holes;

[0061] An air joint 2303 provided on the suction rod 2302, and the air joint 2303 is communicated with the air flow hole.

[0062] The suction head assembly 230 generally can suck the label 51 by means of vacuum suction. In this embodiment, the suction head assembly 230 includes a suction disc 2301, a suction rod 2302, and an air joint 2303. Among them, the suction disc 2301 has a suction surface for sucking the label 51, and suction holes are provided on the suction surface. The suction holes are communicated with the air joint 2303 through the air flow hole of the suction rod 2302. The air joint 2303 can be connected to a vacuum pumping device. When the vacuum pumping device pumps air, a negative pressure can be formed on the suction surface, so that the suction disc 2301 can suck the label 51. The suction rod 2302 can be a part that cooperates with the limiting support member 223 to achieve limitation. At the same time, a limiting boss 2304 for limiting the moving distance of the suction head assembly 230 can also be provided on the suction rod 2302. In addition, a vacuum pressure switch 250 can be provided on the support assembly 220 for detecting the vacuum suction pressure.

[0063] In some embodiments of the present application, the adsorption surface is adapted to the shape of the label 51 and is configured to cover the label 51. The adsorption surface being adapted to the shape of the label 51 means that the shape of the adsorption surface is similar to that of the label 51. For example, if the label 51 is rectangular, then the adsorption surface is also rectangular; if the label 51 is oval, then the adsorption surface is also oval. At the same time, the adsorption surface is configured to cover the label 51, ensuring that the adsorption surface has sufficient area for the label 51 to be attached and pressed tightly, preventing the risk of the label 51 from lifting at the edges and falling off. In the embodiment as Figure 14 shown, the adsorption surface is designed as a rectangle with reference to the label 51, and at the same time, the size is 1 - 1.5 mm larger than the label 51, which can ensure the adsorption effect of the adsorption surface on the label 51.

[0064] Please refer to Figure 11 , in some embodiments of the present application, the driving support member 222 is provided with a second through - hole 2221 for installing the adsorption air pipe 260 and a plurality of third through - holes 2222 for installing the driving components 240. The second through - hole 2221 is a long - strip hole, and a plurality of driving components 240 are respectively installed in a plurality of third through - holes 2222 one - to - one.

[0065] For the adsorption head assembly 230 that utilizes vacuum adsorption, it needs to be connected to the adsorption air pipe 260. Therefore, in this embodiment, the driving support member 222 is provided with a second through - hole 2221, which is a long - strip hole and can install multiple adsorption air pipes 260 at the same time. And there are a plurality of third through - holes 2222 for installing the driving components 240, so that a plurality of driving components 240 are respectively installed in a plurality of third through - holes 2222 one - to - one. In this way, the stability of the installation of the driving components 240 can be ensured, and further the stability of the adsorption head assembly 230 can be ensured.

[0066] Based on the above - mentioned label - sticking and sucking mechanism, the present application further provides a label - sticking device, and the label - sticking device includes the above - mentioned label - sticking and sucking mechanism. This label - sticking device simultaneously attaches a plurality of different labels 51 to a single product 5, realizing the attachment of different labels 51 to a single product 5; or a plurality of adsorption head assemblies 230 can simultaneously adsorb a plurality of identical labels 51 and respectively attach each label 51 to a single product 5, realizing the simultaneous label - sticking of a plurality of products 5, which can improve the label - sticking efficiency.

[0067] Please refer to Figure 9 and Figure 11 , in some embodiments of the present application, the label - sticking device 2 includes a robotic arm 21. The support frame 221 includes a first plate body 2211 and a second plate body 2212. The first plate body 2211 is vertically connected to the end of the second plate body 2212 so that the first plate body 2211 and the second plate body 2212 form an L - shaped structure. The robotic arm 21 is connected to the first plate body 2211, and the driving support member 222 and the limiting support member 223 are arranged on the second plate body 2212.

[0068] The labeling suction mechanism itself can only achieve the movement of the label 51 by the movement of the suction head assembly 230 in the first direction, which usually cannot meet the labeling requirements. Therefore, in this embodiment, the labeling device 2 includes a robotic arm 21. The robotic arm 21 is connected to the labeling suction mechanism to achieve a large-range movement of the label 51, transfer the label 51 from the label output mechanism 20 to the labeling position of the product 5, and then use the drive assembly 240 to drive the suction head assembly 230 to achieve precise labeling.

[0069] To facilitate the connection between the robotic arm 21 and the labeling suction mechanism, in this embodiment, the support frame 221 includes a first plate body 2211 and a second plate body 2212. The first plate body 2211 and the second plate body 2212 form an L-shaped structure, and a reinforcing plate 2213 can be provided at the bending part of the L-shaped structure to strengthen it. The first plate body 2211 of the L-shaped structure can be connected to the robotic arm 21, and its second plate body 2212 can be used to install the drive support 222 and the limit support 223.

[0070] In the production of the product 5, the pasting of the label 51 can play multiple roles such as providing product 5 information, brand promotion and identification, tracking and traceability, and inventory management. Taking the labeling of chassis metal parts as an example, it can mainly ensure the traceability of the production information of each chassis metal part. During the labeling process, there are often problems with poor labeling, resulting in the label 51 being unreadable, which will directly affect subsequent production, inventory, sales and other links.

[0071] For this reason, please refer to Figure 1 and Figure 2 , this embodiment of the present application provides a labeling device, which includes:

[0072] A conveying device 1 for conveying the product 5;

[0073] A labeling device 2, arranged at a first position on the conveying device 1, and the labeling device is configured to paste a label 51 on the product 5 conveyed by the conveying device 1;

[0074] A scanning and detecting device 3, arranged at a second position on the conveying device 1, the second position is located downstream of the first position, and the scanning and detecting device 3 is configured to read the label 51 information of the product 5 and determine whether the label 51 information of the product 5 can be read or not;

[0075] The blanking device 4 is arranged at the third position on the conveying device 1. The third position is downstream of the second position. The blanking device 4 includes a good product blanking mechanism and a defective product blanking mechanism. The blanking device 4 is configured to convey the product 5 whose label 51 information can be read through the good product blanking mechanism according to the judgment of the scanning detection device 3, and convey the product 5 whose label 51 information cannot be read through the defective product blanking mechanism.

[0076] The conveying device 1 is used for conveying the product 5, so that the product 5 can be conveyed to the first position where the labeling device 2 is located, the second position where the scanning detection device 3 is located, and the third position where the blanking device 4 is located. The labeling device 2 is used for the labeling operation of the product 5, and it is the core component in the labeling equipment; the scanning detection device 3 is used for scanning and reading the attached label 51, and can judge whether the label 51 information of the product 5 can be read well. The blanking device 4 is used for separately outputting the product 5 whose label 51 information can be read and the product 5 whose label 51 information cannot be read, so as to obtain the product 5 whose label 51 can be read.

[0077] When the labeling equipment of the present application is in use, the product 5 is conveyed on the conveying device 1. After the product 5 is conveyed to the first position where the labeling device 2 is located, the labeling device 2 can perform the operation of pasting the label 51 on it. After the label 51 is pasted, the product 5 continues to be conveyed to the scanning detection device 3. The scanning detection device 3 can read the label 51 information of the product 5, so as to judge whether the label 51 information of the product 5 can be read or cannot be read. If the label 51 information of the product 5 can be read, it can be determined as a good product. When the scanning identifies that there are defects such as wrong codes / duplicate codes in the label 51 of the product 5, it is determined as a defective product. After being conveyed to the third position where the blanking device 4 is located, the blanking device 4 conveys the good products from the good product blanking mechanism according to the judgment of the scanning detection device 3, and performs the next process of the product 5. The defective products are conveyed from the defective product blanking mechanism, and the defective products can be collected to check the reason why the label 51 cannot be read, and operations such as re-labeling can be carried out.

[0078] Please refer to Figures 4 to 5 In some embodiments of the present application, a positioning mechanism 13 is arranged at at least one of the first position, the second position and the third position on the conveying device 1. The positioning mechanism 13 includes a position sensor 14, a blocking assembly 15 and a lifting assembly; the position sensor 14 is configured to detect whether the product 5 reaches the position where the lifting assembly is located; the blocking assembly 15 is configured to block the product 5 according to the detection of the position sensor 14 and stop the product 5 at the position where the lifting assembly is located; the lifting assembly is configured to lift the product 5 stopped at the position where the lifting assembly is located, so that the product 5 is separated from the conveying of the conveying device 1.

[0079] Some products 5 can be labeled, scanned, and inspected while they are moving on the conveyor 1. However, this is generally difficult to do, and most products 5 cannot be labeled, scanned, or inspected while they are moving. In this embodiment, positioning mechanisms 13 are provided at the first, second, and third positions on the conveyor 1. These positioning mechanisms 13 can be used to position the products 5 at each of these three positions, making labeling, scanning, and inspection much easier for the positioned products 5.

[0080] The positioning mechanism 13 includes a position sensor 14, a blocking component 15 and a lifting component. The position sensor 14 can detect whether the product 5 has reached the positioning position, that is, the position of the lifting component in the three processes. The position sensor 14 can be a contact sensor, a photoelectric sensor, a laser sensor or other non-contact sensor. Figure 5 As shown, when the position sensor 14 can detect that the product 5 has reached the positioned position, the blocking mechanism can stop the product 5 from continuing to move forward. The blocking mechanism can use a motor, cylinder or other driving parts in combination with a blocking block. The position of the blocking mechanism is usually downstream of the position where the product 5 reaches the positioned position. It can also be designed according to the specific structure of the product 5. For example, a blocking component 15 can be set corresponding to the holes or depressions of the product 5.

[0081] The blocking assembly 15 can only temporarily stop the product 5, and the product 5 is still on the conveying device 1. Therefore, this embodiment is also provided with a lifting assembly, such as Figure 6 As shown, after the blocking assembly 15 stops the product 5, the lifting assembly lifts the product 5 and removes it from the conveyor 1, thereby positioning the product 5 for labeling, scanning, sorting, etc. When the operation at this position is completed, the lifting assembly can be controlled to descend, returning the product 5 to the conveyor 1. At the same time, the blocking assembly 15 is removed, and the conveyor 1 continues to convey the product 5 to the next position.

[0082] It should be noted that the positioning mechanism 13 may be located in only one of the first, second, and third positions, or may be located in multiple positions, depending on the specific situation. For example, if the scanning and detection device 3 can accurately identify the labels 51 on the moving products 5, then the positioning mechanism 13 may not be located in the corresponding second position. Similarly, if the unloading device 4 can directly sort and unload the moving products 5, then the positioning mechanism 13 may not be located in the corresponding third position.

[0083] See also Figure 4, in some embodiments of the present application, the lifting assembly includes a lifting driving member 131, a lifting plate 132, and a positioning structure 133 for positioning the product 5. The lifting plate 132 is disposed on the lifting driving member 131, and the positioning structure 133 is disposed on the lifting plate 132. The function of the lifting assembly is to lift the product 5 so that it is separated from the conveying of the conveying device 1. Its specific structure can be designed according to the lifted product 5. In this embodiment, the lifting assembly includes a lifting driving member 131, a lifting plate 132, and a positioning structure 133. Among them, the lifting driving member 131 can adopt common driving members such as cylinders and electric cylinders. The lifting plate 132 provides a relatively stable platform for lifting the product 5. The positioning structure 133 can ensure the stability of the product 5 on the lifting plate 132. The positioning structure 133 can adopt various methods such as concave-convex mating positioning and clamping positioning.

[0084] Please refer to Figure 4 , in some embodiments of the present application, a carrying mechanism 12 for carrying the product 5 is provided on the conveying device 1, and the lifting assembly is configured to lift the carrying mechanism 12 to lift the product 5; a positioning hole is provided on the carrying mechanism 12, and the positioning structure 133 is a positioning post, and the positioning post is configured to penetrate into the positioning hole in a state where the lifting assembly lifts the carrying mechanism 12.

[0085] It is relatively troublesome to design different lifting products 5 for different products 5, and it is relatively difficult to design corresponding lifting assemblies for many products 5 with various shapes. In this embodiment, a carrying mechanism 12 for carrying the product 5 is provided on the conveying device 1, and the product 5 is placed on the carrying mechanism 12 for conveying. The carrying mechanism 12 can be designed according to the product 5. Since the carrying mechanism 12 will not be separated from the product 5 during the labeling and scanning processes, the design difficulty is relatively low, as long as it is ensured that the carrying mechanism 12 can stably carry the product 5. The carrying mechanism 12 can be designed into various shapes such as plate-shaped and frame-shaped according to the product 5.

[0086] A positioning hole is provided on the carrying mechanism 12, and the positioning structure 133 on the lifting plate 132 is a positioning post. The positioning post penetrates into the positioning hole in a state where the lifting assembly lifts the carrying mechanism 12, which can realize the stable positioning of the carrying mechanism 12, and further realize the positioning of the product 5. Performing positioning between the carrying mechanism 12 and the lifting assembly can improve the convenience of positioning compared to directly positioning the product 5, and it is not easy to cause damage to the product 5. In addition to using the positioning post to cooperate with the positioning hole for positioning, a quick clamp 16 can also be provided on the lifting plate 132 to clamp the carrying mechanism 12 with the quick clamp 16 to further improve the stability.

[0087] Please refer to Figures 1 to 3, in some embodiments of the present application, the conveying device 1 includes a double-layer return plate conveying line body 10 and a carrier lifting mechanism 11. The double-layer return plate conveying line body 10 includes an upper conveying line body 101 and a lower return line body 102 arranged in a stacked manner. The carrier lifting mechanism 11 includes a first carrier lifting mechanism 11 and a second carrier lifting mechanism 11. The first carrier lifting mechanism 11 is arranged at one end of the double-layer return plate conveying line body 10 to control the carrier mechanism 12 to move from the upper conveying line body 101 to the lower return line body 102; the second carrier lifting mechanism 11 is arranged at the other end of the double-layer return plate conveying line body 10 to control the carrier mechanism 12 to move from the lower return line body 102 to the upper conveying line body 101.

[0088] The conveying device 1 can adopt different structures according to different products 5 to be conveyed. For example, it can be a conveyor belt, a roller conveying line, a chain plate conveying line, etc. In the case where there is a carrier mechanism 12, it is advisable to adopt the double-layer return plate conveying line body 10 of this embodiment. As the name implies, the double-layer return plate conveying line body 10 includes an upper conveying line body 101 and a lower return line body 102 arranged in a stacked manner. The upper conveying line body 101 is used to convey the product 5, and the lower return line body 102 is used to convey the returned carrier mechanism 12. In order to enable the carrier mechanism 12 to move from the upper conveying line body 101 to the lower return line body 102 at one end of the double-layer return plate conveying line, and from the lower return line body 102 to the upper conveying line body 101 at the other end, so that it can be better reused. A first carrier lifting mechanism 11 is arranged at one end of the double-layer return plate conveying line body 10 to control the carrier mechanism 12 to move from the upper conveying line body 101 to the lower return line body 102, and a second carrier lifting mechanism 11 is arranged at the other end of the double-layer return plate conveying line body 10 to control the carrier mechanism 12 to move from the lower return line body 102 to the upper conveying line body 101.

[0092] A robotic arm 21 connected to the label picking mechanism 22, and the robotic arm 21 is configured to move the labels 51 picked up by the label picking mechanism 22 to the product 5 for attachment.

[0093] The labeling device 2 is the core of the entire labeling equipment. According to the different products 5 to be labeled, an existing labeling device 2 can be adopted. In this embodiment, the labeling device 2 includes a label output mechanism 20, and the label output mechanism 20 is used to output labels 51. The labeling suction mechanism 22 can suck the labels 51 output by the label output mechanism 20, and the robotic arm 21 is connected to the labeling suction mechanism 22 and can move within a relatively large range, so as to move the labels 51 sucked by the labeling suction mechanism 22 to the product 5 for attachment. In some embodiments, the label output mechanism 20 can strip and convey the printed labels 51 in order to the position of the label output platform 201. After several fiber optic sensors arranged below the position of the label output platform 201 detect that the labels are output in place, the robotic arm 21 drives the labeling suction mechanism 22 above the position of the label output platform 201, adsorbs the labels 51 by using the labeling suction mechanism 22, and then performs labeling.

[0094] Please refer to Figure 7 and Figure 8 , in some embodiments of the present application, the scanning and detecting device 3 includes a scanning bracket 30, a scanning lens 31 and a light source 32. The scanning lens 31 and the light source 32 are both arranged on the scanning bracket 30 and face the conveying device 1. Among them, the scanning bracket 30 is used to install the scanning lens 31 and the light source 32 in a suitable position. The scanning lens 31 can photograph the product label 51 to be scanned, so as to read the product 5 information corresponding to the label 51. The scanning result can be fed back to the general controller, and at the same time, the product label 51 information is uploaded to the company's manufacturing execution system to ensure the traceability of the product 5 manufacturing process and facilitate the manufacturing of subsequent processes. The light source 32 can supplement light for the scanning of the scanning lens 31 to ensure the scanning effect. The scanning lens 31 and the light source 32 both face the conveying device 1 to facilitate scanning the label 51 and supplementing light for the label 51.

The product grasping part 41 is configured to grasp defective products. One end of the vertical driving structure 42 is connected to the product grasping part 41, and the other end is connected to the horizontal driving structure 43.

[0096] Under normal circumstances, the number of qualified products whose label 51 information can be read is much larger than the number of defective products whose label 51 information cannot be read. Therefore, the qualified product discharging mechanism can usually directly adopt the original conveying path of the conveying device 1 for direct conveying. Since the number of defective products is small, a separate defective product discharging mechanism can be installed. In this embodiment, the defective product discharging mechanism includes a product 5 grasping part 41, a vertical driving structure 42 and a horizontal driving structure 43. Among them, the product 5 grasping part 41 is used to grasp defective products, the vertical driving structure 42 is used to control the product 5 grasping part 41 to move vertically, and the horizontal driving structure 43 is used to control the product 5 grasping part 41 to move horizontally. For example, when a defective product is detected, the product 5 grasping part 41 can be moved vertically downward to the defective product through the vertical driving structure 42, and the defective product is grasped by the product 5 grasping part 41. Then, the defective product is separated from the conveying device 1 vertically through the vertical driving structure 42, and then horizontally moved outside the conveying device 1 through the horizontal driving structure 43 and placed in a designated position. A defective product box 44 can be set at the designated position for preventing defective products to store defective products. Both the vertical driving structure 42 and the horizontal driving structure 43 adopt various existing driving structures such as air cylinders and electric cylinders.

The product 5 grasping part 41 can adopt various methods such as clamping and adsorption. In this embodiment, the product 5 grasping part 41 includes a grasping plate 411 and an electromagnetic suction member 412. When the electromagnetic suction member 412 is energized, it can generate a magnetic suction force to adsorb the product 5.
