Description

Technical Field

[0001] The present invention relates to a detection device, and in particular to an automatic radium code sorting device and method. Background Art

[0002] During the production process, laser marking QR codes on the surface of materials can facilitate traceability. Generally, the last digits of the laser QR code information include the date and acupuncture point number. For materials that undergo multiple processes, after the previous process is completed, relevant information from the previous process, including the date and acupuncture point number, is printed on the surface to facilitate production traceability. However, after the materials have undergone processing in the previous process, they are disrupted. When loaded onto pallets for the laser marking process, the materials loaded onto the same pallet may not contain the same date or acupuncture point. Subsequently, when using a mask to laser mark the materials with the new QR code information, the date and acupuncture point information from the previous process must be sorted and organized before laser marking, which is inconvenient. Currently, materials are manually sorted and organized according to the date and acupuncture point number information on the materials before being placed on the pallets. This process is labor-intensive, inefficient, and prone to errors. Individual QR codes may not match the actual date and acupuncture point number information, and the materials are directly transferred to subsequent processes, ultimately affecting product yield. Summary of the Invention

[0003] In response to the above technical problems, the present invention discloses an automatic laser code sorting device and method, which improves production efficiency and product qualification rate.

[0004] To this end, the technical solution of the present invention is:

[0007] The visual recognition component and the laser code mechanism are connected to the control module. The visual recognition component feeds back the relevant information on the identified material to the control module. The control module generates a QR code based on the relevant information on the currently identified material in combination with other process information. When the turntable drives the material to the laser code station, the control module controls the laser code mechanism to generate a QR code and laser engrave it on the surface of the material. The turntable drives the material to the code scanning station, and the code reader recognizes the QR code of the material and feeds back the recognition result to the unloading robot. The unloading robot places the material in the good product unloading area or the defective product unloading area based on the feedback result. Among them, the control module can adopt a programmable logic controller or computer of the existing technology.

[0008] With this technical solution, materials are loaded at the loading station through the loading component, and then the visual recognition component recognizes the date and acupoint number printed on the current material, and then feeds it back to the control module. The control module generates a QR code based on this information combined with other process information, and transmits the QR code information to the laser code mechanism. The laser code mechanism directly lasers the QR code on the surface of the material. At the scanning station, the code reader recognizes the QR code. If there is an error in the recognition or it cannot be recognized, the information is fed back to the unloading robot at the unloading station. The unloading robot grabs the material to the defective product unloading area. If it can be recognized normally, the unloading robot grabs the material to the good product unloading area. This technical solution can process a batch of materials with mixed information such as different dates or acupoint numbers without manual classification and collation, and then laser coding.

[0060] The preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0061] Example 1

[0062] like Figures 1 to 3As shown, an automatic radium code sorting device includes a frame 500, on which a loading module 300, a radium code inspection module 100 and a sorting module 200 are provided. The radium code inspection module 100 includes a turntable 10; the turntable 10 is provided with a plurality of product processing positions along the circumference, and each product processing position is provided with a fixture 11 for placing the product; along the rotation direction of the turntable 10, a loading station 20, a visual recognition station 30, a radium code station 40, a code scanning station 50, a material unloading station 60 and a cleaning station 70 are sequentially provided, a total of six stations, the turntable 10 Six corresponding product processing stations are located on the turntable 10. The loading module 300 is located on one side of the loading station 20 and includes a loading assembly. The visual recognition station 30 is equipped with a visual recognition assembly, the radium code station 40 is equipped with a radium code mechanism, and the code scanning station 50 is equipped with a code reader 51. The sorting module 200 is located on one side of the unloading station 60. The cleaning station 70 is located between the loading station 20 and the unloading station 60 and is equipped with a compressed air nozzle 71, which is directed towards the product processing stations on the turntable 10. The sorting module 200 includes a unloading robot 201, a good product unloading area 202, and a defective product unloading area 203. The visual recognition assembly and radium code mechanism are connected to a control module, which can be a conventional programmable logic controller or computer. The control module includes software for generating QR codes.

[0063] Specifically, the loading mechanism includes a loading and transplanting assembly 301 and a loading conveyor line 302 for transporting a tray 400 loaded with materials. The loading and transplanting assembly 301 is located above the conveyor line. Both the loading and transplanting assembly 301 and the conveyor line can adopt existing technologies.

[0064] The visual recognition component includes a camera 31 and a visual recognition module containing image recognition software. Further, the camera 31 adopts a 500W pixel camera 31. The visual recognition module adopts existing technology.

[0065] The laser code mechanism includes a laser marking machine 41 , and the head of the laser marking machine 41 faces the product processing position of the turntable 10 .

[0066] The code reader 51 is a Keyence SR2000 code scanner.

[0067] The good product unloading area 202 and the defective product unloading area 203 are respectively equipped with a good product conveyor line 204 and a defective product conveyor line 205. Trays 400 for loading materials are placed on both the good product conveyor line 204 and the defective product conveyor line 205. The unloading robot 201 is located between the good product unloading area 202 and the defective product unloading area 203. Furthermore, the unloading robot 201 is a swing arm robot.

[0068] Furthermore, the turntable 10 is connected to the rotation drive mechanism via a cam indexer. The rotation drive mechanism drives the turntable 10 to rotate, wherein the cam indexer can improve the angular accuracy of each rotation of the turntable 10, which is beneficial to the precise operation of each workstation process.

[0069] Furthermore, the cleaning station 70 is equipped with a sensor for detecting whether the jig 11 is empty. The sensor is directed toward the jig 11 at the product processing position of the turntable 10. Furthermore, the sensor is connected to an alarm module. This technical solution can sense the situation inside the jig 11 and, if the material inside the jig 11 is not removed in a timely manner, a prompt alarm can be issued.

[0070] Using the device of this embodiment, the material is sorted by radium code according to the following method:

[0071] The material is loaded on the tray 400 in other processes and transported to one side of the loading station 20 via the loading conveyor line 302 at the loading station 20. The loading and transferring assembly 301 grabs the material on the tray 400 and places it on the jig 11 of the turntable 10.

[0072] As the turntable 10 rotates, the material moves to the visual recognition station 30, where the camera 31 captures an image of the material surface and identifies the date and acupuncture point number printed on the material, and feeds this information back to the control module. The control module generates a QR code based on this information combined with other process information and transmits the QR code information to the laser code mechanism.

[0073] As the turntable 10 rotates, the material is transferred to the laser marking station 40, and the laser marking machine 41 directly lasers the QR code on the surface of the material;

[0074] The material is transferred to the code scanning station 50 along with the turntable 10, and the code reader 51 recognizes the QR code. If there is a recognition error or the code cannot be recognized, the information is fed back to the unloading robot 201 at the unloading station 60;

[0075] As the turntable 10 rotates, the material is transferred to the unloading station 60, and the unloading robot 201 grabs the material and places it on the tray 400 of the defective product conveyor line 205. If the material can be identified normally, the unloading robot 201 grabs the material and places it on the tray 400 of the good product conveyor line 204.

[0076] As the turntable 10 rotates, the jig on the turntable 10 reaches the cleaning station 70 , and the compressed air nozzle 71 cleans the product processing position of the turntable 10 .

[0077] By adopting the above method, for a batch of materials with mixed information such as different dates or acupoint numbers, there is no need to manually classify and organize them, and then digitize them. Instead, it is only necessary to load the material assembly onto the turntable, and the digitizing will be automatically performed as the turntable rotates. The overall production efficiency is improved, the amount of manual work is greatly reduced, and the defects caused by improper manual operation are reduced. Moreover, the structure of the entire device is compact and occupies a small area.

[0078] Example 2

[0079] On the basis of Example 1, Figures 3 to 6 As shown, the turntable 10 is provided with several product processing positions along the circumference, and each product processing position is provided with a jig 11 for placing products, and the jig 11 includes a product placement area 121, and the two connected sides outside the product placement area 121 are respectively provided with a first limiting mechanism 122 and a second limiting mechanism 123, and the first limiting mechanism 122 and the second limiting mechanism 123 are used to limit the products in the product placement area 121 in two horizontal orthogonal directions.

[0080] The loading station 20 and the unloading station 60 are both provided with a positioning drive mechanism 12 below the first limiting mechanism 122 and the second limiting mechanism 123 . The positioning drive mechanism 12 is fixedly connected to the frame 500 .

[0081] The positioning drive mechanism 12 includes a first positioning member, a second positioning member, and a lifting cylinder 151. The first positioning member is located directly below the first limiting mechanism 122, and the second positioning member is located directly below the second limiting mechanism 123. The first positioning member includes a first inclined top 152, and the second positioning member includes a second inclined top 153. The lifting cylinder 151 is connected to the first inclined top 152 and the second inclined top 153 via a connecting block 154. The inclined surfaces of the first inclined top 152 and the second inclined top 153 are arranged outward. The two positioning members are driven by a single lifting cylinder 151, resulting in a simple structure and low cost.

[0082] Specifically, the first limiting mechanism 122 and the second limiting mechanism 123 have the same structure. The first limiting mechanism 122 will be described below as an example. The first limiting mechanism 122 includes a limiting column 124 and a push plate 125. One end of the limiting column 124 extends into the product placement area 121, and the other end of the limiting column 124 is connected to the push plate 125. The first inclined top 152 is located directly below the push plate 125, and the lower end of the push plate 125 is provided with a pulley 126 for contacting the inclined top. The lifting cylinder 151 drives the first inclined top 152 to move upward, so that the first inclined top 152 contacts the push plate 125, and the inclined surface of the first inclined top 152 drives the limiting column 124 to slide out of the product placement area 121. The turntable 10 is provided with a guide mechanism located below the fixture 11, which moves in the same direction as the push plate 125. The guide mechanism includes a guide rail 112 and a guide plate 113. Furthermore, the guide rail 112 is located at the bottom of the turntable 10, one end of the guide plate 113 is connected to the push plate 125, and the guide plate 113 is connected to the guide rail 112 via a slider. The guide plate 113 is connected to the turntable 10 via a tension spring 111. The same is true for the second limiting mechanism 123.

[0083] The jig 11 is provided with a notch 127 at each of the limiting posts 124 corresponding to the first limiting mechanism 122 and the second limiting mechanism 123. The width of the notch 127 is not less than the width of the limiting post 124, and the limiting post 124 extends into or out of the notch 127. The limiting posts 124 of the first limiting mechanism 122 and the limiting posts 124 of the second limiting mechanism 123 are arranged orthogonally.

[0084] Using this technical solution, two limiting mechanisms are provided on each fixture 11, and fixed positioning drive mechanisms 12 are only provided at the loading station 20 and the unloading station 60. The positioning drive mechanism 12 does not need to rotate with the turntable 10, and the positioning drive mechanism 12 is separated from the limiting mechanism. When loading at the loading station 20 or unloading at the unloading station 60, the positioning drive mechanism 12 pushes the limiting mechanism to open the product placement area 121, allowing the product to be placed in or taken out. After the product is placed in or taken out, the lifting cylinder 151 drives the two inclined pushers to descend, separating them from the push plate 125. Under the action of the tension spring 111, the push plate 125 drives the limiting column 124 along the guide rail 112 to return to its original position. The technical solution of this embodiment does not require each limiting mechanism to be equipped with a positioning drive mechanism 12, and the positioning drive mechanism 12 does not need to rotate with the turntable 10. Therefore, the wiring connecting the positioning drive mechanism 12 is simple, easy to install and maintain, and low in cost.
