Detailed implementation manners

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer and more understandable, 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.

[0049] 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.

[0050] It should be understood that the orientation or positional relationship indicated by the terms "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 accompanying drawings, and 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, and therefore cannot be understood as a limitation to the present application.

[0051] 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, "a plurality of" means two or more unless otherwise specifically defined.

[0052] In the production of the product 5, the pasting of the label 51 can play roles in providing product 5 information, brand promotion and identification, tracking and traceability, inventory management, etc. Taking the labeling of the metal parts of the chassis as an example, it can mainly ensure the traceability of the production information of each metal part of the chassis. Since there are often poor labeling problems during the labeling process, resulting in the label 51 not being readable, this will directly affect subsequent production, inventory, sales and other links.

[0053] Please refer to Figure 1 and Figure 2 , in view of the above problems, the embodiment of the present application provides a labeling device, and the labeling device includes:

[0054] A conveying device 1 for conveying the product 5;

[0055] A labeling device 2 is disposed at a first position on the conveying device 1, and the labeling device is configured to paste the label 51 on the product 5 conveyed by the conveying device 1;

[0056] A scanning detection device 3 is disposed at a second position on the conveying device 1. The second position is downstream of the first position. The scanning detection device 3 is configured to read the information of the label 51 of the product 5 and determine whether the information of the label 51 of the product 5 can be read or cannot be read.

[0057] A blanking device 4 is disposed at a 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 with readable label 51 information through the good product blanking mechanism and convey the product 5 with unreadable label 51 information through the defective product blanking mechanism according to the judgment of the scanning detection device 3.

[0058] 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 is the core component of the labeling equipment; the scanning detection device 3 is used for scanning and reading the attached label 51 and can judge whether the information of the label 51 of the product 5 can be read well. The blanking device 4 is used for separately outputting the product 5 with readable label 51 information and the product 5 with unreadable label 51 information, so as to obtain the product 5 with readable label 51.

[0059] 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. 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 information of the label 51 of the product 5, so as to judge whether the information of the label 51 of the product 5 can be read or cannot be read. If the information of the label 51 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 code / duplicate code 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 product from the good product blanking mechanism according to the judgment of the scanning detection device 3 and executes the next process of the product 5. The defective product is conveyed from the defective product blanking mechanism, and the reasons why the label 51 cannot be read can be collected, and operations such as re-labeling can be performed.

[0060] Please refer to Figures 4 to 5, in some embodiments of the present application, a positioning mechanism 13 is provided 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.

[0061] Some products 5 can perform operations such as labeling and scanning detection during the movement on the conveying device 1, but usually the operation difficulty is relatively large, and most products 5 are difficult to perform these operations during the movement. In this embodiment, positioning mechanisms 13 are respectively provided at the first position, the second position, and the third position on the conveying device 1. Here, at these three positions, the product 5 can be respectively positioned by the positioning mechanism 13, and it will be much easier to perform operations such as labeling and scanning detection on the positioned product 5.

[0062] The positioning mechanism 13 includes a position sensor 14, a blocking assembly 15, and a lifting assembly. Among them, the position sensor 14 can detect whether the product 5 reaches the positioned position, that is, the position where the lifting assembly is located in the three processes. The position sensor 14 can adopt contact sensors and non-contact sensors such as photoelectric sensors and laser sensors. For example Figure 5 As shown, when the position sensor 14 can detect that the product 5 reaches the positioned position, the blocking mechanism can block the continuous advancement of the product 5. The blocking mechanism can adopt driving parts such as motors and cylinders in cooperation with blocking blocks, etc. The position of the blocking mechanism is usually downstream of the position where the product 5 reaches the positioned position, and it can also be designed according to the specific structure of the product 5. For example, the blocking assembly 15 is provided corresponding to the holes or depressions of the product 5, etc.

[0063] The blocking assembly 15 can only play a role in temporarily stopping the product 5, and the product 5 is still on the conveying device 1. Therefore, in this embodiment, a lifting assembly is also provided. As Figure 6 shown, after the blocking assembly 15 stops the product 5, the lifting assembly lifts the product 5 so that the product 5 is separated from the conveying of the conveying device 1, thereby realizing the positioning of the product 5 to facilitate operations such as labeling, scanning, and classification. After the operation at this position is completed, the lifting assembly can be controlled to descend so that the product 5 returns to the conveying device 1, and at the same time, the blocking assembly 15 is moved away, and the conveying device 1 continues to convey the product 5 to the next position.

[0064] It should be specifically noted that the positioning mechanism 13 can be provided only at one of the first position, the second position, and the third position, or can be provided at multiple positions, which can be determined according to the specific situation. For example, if the scanning and detecting device 3 can accurately identify the label 51 on the moving product 5, the positioning mechanism 13 may not be provided at the corresponding second position. Similarly, if the blanking device 4 can directly classify and blank the moving product 5, there is no need to provide the positioning mechanism 13 at the corresponding third position.

[0065] Please refer to 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, and 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 fitting positioning and clamping positioning.

[0066] 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.

[0067] It is rather troublesome to design different lifting products 5 for different products 5, and it is rather 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.

[0068] The bearing mechanism 12 is provided with positioning holes, and the positioning structure 133 on the lifting plate 132 is a positioning post. The positioning post is inserted into the positioning holes when the lifting assembly lifts the bearing mechanism 12, which can achieve the stable positioning of the bearing mechanism 12, and further achieve the positioning of the product 5. Positioning is carried out between the bearing mechanism 12 and the lifting assembly. Compared with directly positioning the product 5, it can improve the convenience of positioning and is not likely 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 bearing mechanism 12 with the quick clamp 16, further improving the stability.

[0069] 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 movement of the bearing mechanism 12 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 movement of the bearing mechanism 12 from the lower return line body 102 to the upper conveying line body 101.

[0070] The conveying device 1 can adopt different structures according to different products 5 to be conveyed. For example, a conveyor belt, a roller conveying line, a chain plate conveying line, etc. For the case where the bearing mechanism 12 is provided, 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 bearing mechanism 12. In order to enable the bearing 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 movement of the bearing mechanism 12 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 movement of the bearing mechanism 12 from the lower return line body 102 to the upper conveying line body 101.

[0071] Please refer to Figures 7 to 8 , in some embodiments of the present application, the labeling device 2 includes:

[0072] A label output mechanism 20 for outputting labels 51;

[0073] The label sticking suction mechanism 22 is used to suck out the label 51 output by the label output mechanism 20;

[0074] The robotic arm 21 is connected to the label sticking suction mechanism 22, and the robotic arm 21 is configured to move the label 51 sucked by the label sticking suction mechanism 22 to the product 5 for sticking.

[0075] The label sticking device 2 is the core of the entire label sticking equipment. According to different products 5 to be labeled, an existing label sticking device 2 can be adopted. In this embodiment, the label sticking device 2 includes a label output mechanism 20, and the label output mechanism 20 is used to output the label 51. The label sticking suction mechanism 22 can suck out the label 51 output by the label output mechanism 20, and the robotic arm 21 is connected to the label sticking suction mechanism 22 and can move within a relatively large range, so as to move the label 51 sucked by the label sticking suction mechanism 22 to the product 5 for sticking. In some embodiments, the label output mechanism 20 can orderly strip and convey the printed label 51 to the position of the label output platform 201. After several fiber optic sensors arranged below the label output platform 201 detect that the label output is in place, the robotic arm 21 drives the label sticking suction mechanism 22 above the label output platform 201, uses the label sticking suction mechanism 22 to adsorb the label 51, and then performs label sticking.

[0076] Please refer to Figures 9 to 10 , in some embodiments of the present application, the label sticking suction mechanism includes:

[0077] 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 arranged on the support frame 221 at intervals;

[0078] 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;

[0079] A plurality of driving assemblies 240 are arranged on the driving support member 222, and 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.

[0080] Most current label sticking devices use a single suction head assembly 230 to suck out the label 51. If different labels 51 need to be stuck on the same product 5 at the same time or there are multiple products 5 in the same jig, step-by-step operations need to be adopted, and this operation method has low efficiency, seriously affecting the label sticking efficiency of the product 5; while manual label sticking consumes manpower, has high requirements for label sticking accuracy, and may lead to unsatisfactory label sticking effects, such as the label 51 being stuck crookedly, falling off, and low consistency of finished products due to unstable work quality of people.

[0081] In this embodiment, a driving support member 222 and a limiting support member 223 are provided on the support assembly 220, which can respectively support a plurality of suction head assemblies 230 and a plurality of driving assemblies 240. The suction head assembly 230 can move along the first direction under the limiting action of the limiting support member 223, so as to realize the precise small-range movement of the label 51, accurately pick up the label 51 and realize the pasting of the label 51. It can be seen that the local direction here refers to the moving direction when the suction head assembly 230 picks up and attaches the label 51. 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, so that each suction head assembly 230 can move up and down independently, that is, each suction head assembly 230 can independently adsorb a label 51. The plurality of suction head assemblies 230 can be used to adsorb a plurality of different labels 51, and simultaneously attach the plurality of different labels 51 to a product 5 to realize attaching different labels 51 to a product 5; or the plurality of suction head assemblies 230 can simultaneously adsorb a plurality of identical labels 51, and respectively attach each label 51 to a product 5 to realize simultaneous labeling of a plurality of products 5, which can improve the labeling efficiency.

[0082] Please refer to Figure 11 and Figure 12 , in some embodiments of the present application, the limiting support member 223 is provided with a first through hole 2231 along the first direction. The suction head assembly 230 is inserted into the first through hole 2231, and the suction head assembly 230 is slidably matched with the limiting support member 223, so that the suction head assembly 230 can move along the first direction under the limiting action of the limiting support member 223.

[0083] The main function of the limiting support member 223 is to limit the suction head assembly 230 in the first direction, so as to ensure that the suction head assembly 230 does not shake during the movement and ensure the stability of the label 51 picking and pasting. The limiting support member 223 can adopt structures such as a guide hole and a guide groove. In this embodiment, the limiting support member 223 is provided with a first through hole 2231 along the first direction. The suction head assembly 230 is inserted into the first through hole 2231, and the first through hole 2231 can play the role of a guide hole to enable the suction head assembly 230 to move stably along the first direction.

[0084] 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 with three groove structures, and the number of 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.

[0085] 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 not be easy to connect the driving assembly 240. In this embodiment, the first through hole 2231 that provides a limiting function for the suction head assembly 230 is a T-shaped hole. The T-shaped hole can be divided into three slots, and the three suction head assemblies 230 are respectively arranged in the three slot structures of the first through hole 2231. 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 the limiting function of the first through hole 2231 on the suction head assembly 230 can be ensured.

[0086] 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.

[0087] 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 can no longer move, 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 it can be avoided 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. 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 the limiting boss 2304 is not provided on the adjacent side surfaces to avoid the limiting boss 2304 interfering with the movement of the suction head assembly 230.

[0088] 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 222 has a first boss 2223, and the limiting support 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.

[0089] The limiting support member 223 and the driving support member 222 can be connected to the support frame 221 by welding, bolt connection, etc. In order 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. That is, through the interaction between the positioning holes and the bosses, the position of the limiting support member 223 and the driving support member 222 connected to the support frame 221 is ensured to be accurate.

[0090] See also Figure 14 In some embodiments of the present application, the adsorption head assembly 230 includes:

[0091] The adsorption plate 2301 has an adsorption surface for adsorbing the label 51, and adsorption holes are provided on the adsorption surface;

[0092] The adsorption rod 2302 is connected to the adsorption plate 2301, and an air flow hole is provided in the adsorption rod 2302, and the air flow hole is connected to the adsorption hole;

[0093] The air connector 2303 is disposed on the adsorption rod 2302, and the air connector 2303 is connected to the air flow hole.

[0094] The adsorption head assembly 230 can usually absorb the label 51 by vacuum adsorption. In this embodiment, the adsorption head assembly 230 includes an adsorption disc 2301, an adsorption rod 2302 and a gas joint 2303, wherein the adsorption disc 2301 has an adsorption surface for adsorbing the label 51, and an adsorption hole is provided on the adsorption surface. The adsorption hole is connected to the gas joint 2303 through the air flow hole of the adsorption rod 2302. The gas joint 2303 can be connected to a vacuum pumping device, and the vacuum pumping device can form a negative pressure on the adsorption surface, so that the adsorption disc 2301 can adsorb the label 51. The adsorption rod 2302 can be used as a position to cooperate with the limit support 223 to achieve limit, and the limit boss 2304 for limiting the moving distance of the adsorption head assembly 230 can also be set on the adsorption rod 2302. In addition, a vacuum pressure switch 250 can be set on the support assembly 220 for detecting the vacuum adsorption pressure.

[0095] In some embodiments of the present application, the adsorption surface is adapted to the shape of the label 51, and the adsorption surface is configured to cover the label 51. The adsorption surface is adapted to the shape of the label 51 means that the shape of the adsorption surface is similar to the shape of the label 51. For example, if the label 51 is rectangular, the adsorption surface is also rectangular; if the label 51 is elliptical, the adsorption surface is also elliptical. At the same time, the adsorption surface can cover the label 51, ensuring that the adsorption surface has enough area for the label 51 to be attached and pressed tightly, preventing the risk of the label 51 from tilting and falling off. Figure 14In the illustrated embodiment, the adsorption surface is designed with a reference label 51 in a rectangular shape, and its 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.

[0096] 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 the plurality of driving components 240 are respectively installed in the plurality of third through holes 2222.

[0097] 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 the plurality of driving components 240 are respectively installed in the plurality of third through holes 2222. 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.

[0098] Please refer to Figure 9 and Figure 11 , in some embodiments of the present application, the labeling 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.

[0099] The labeling suction mechanism itself can only rely on the movement of the adsorption head assembly 230 in the first direction to realize the movement of the label 51, 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 realize the 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 driving component 240 to drive the adsorption head assembly 230 to realize precise labeling.

A reinforcing plate 2213 can be arranged 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 driving support member 222 and the limiting support member 223.

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 capture the label 51 of the product 5 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 total controller, and at the same time, the product 5 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, so as 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.

One end of the vertical driving structure 42 is connected to the product 5 grasping part 41, and the other end is connected to the horizontal driving structure 43.

[0103] Under normal circumstances, the number of good 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 good 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 defective product discharging mechanism can be installed separately. 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 can be grasped by using the product 5 grasping part 41. Then, the defective product can be separated from the conveying device 1 vertically through the vertical driving structure 42, and then moved horizontally 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. The vertical driving structure 42 and the horizontal driving structure 43 both adopt a variety of existing driving structures such as air cylinders and electric cylinders.
