Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In addition, in the drawings, structures with similar or identical structures are represented by the same reference numerals.

[0031] Reference Figures 1 to 4 , which shows an embodiment of the automatic code scanning device provided by the utility model. The structure and working principle of the automatic code scanning device are described in detail below in conjunction with the drawings of the specification. The automatic code scanning device is used to be arranged in conjunction with the assembly line 200, and the assembly line 200 is used to transport air-conditioning components with barcodes. The automatic code scanning device includes a frame 10, a positioning mechanism 20 and a scanning mechanism 30: the frame 10 defines a code scanning area 101 on the upper side of the assembly line 200; the positioning mechanism 20 is arranged on the frame 10 and is located on one side of the code scanning area 101, and the positioning mechanism 20 is used to fix the position of the air-conditioning component in the code scanning area 101; the scanning mechanism 30 is arranged adjacent to the code scanning area 101, and the scanning mechanism 30 is used to scan the barcode of the air-conditioning component in the code scanning area 101.

[0032] In the specific implementation, the automatic code scanning device is set up together with the assembly line 200. The assembly line 200 is used to transport air-conditioning components. The assembly line 200 can be a conveyor belt type assembly line 200, or a roller line type assembly line 200. This embodiment is described with a roller line conveyor belt type assembly line 200. When the roller line of the assembly line 200 moves, it drives the air-conditioning components to move. The air-conditioning components are produced by the previous production process. Barcodes are provided on the air-conditioning components, specifically MES barcodes or other types of barcodes. The barcodes of the air-conditioning components are mainly used to record the production data of the air-conditioning components to facilitate product tracking and management. The air-conditioning components flow into the assembly line 200 in the previous production process and are transported to the automatic code scanning device by the assembly line 200. The automatic code scanning device is mainly used to confirm whether the air-conditioning components meet the standards in the previous production process. The automatic code scanning device as a whole is composed of a frame 10, a positioning mechanism 20 and a scanning mechanism 30. The frame 10 is a part of the frame of the automatic code scanning device. The frame 10 as a whole is a table structure. The upper side of the frame 10 is the assembly line 200. The upper side of the frame 10 defines a code scanning area 101 on the upper side of the assembly line 200, that is, the code scanning area 101 is an area on the upper side of the assembly line 200. The code scanning area 101 is the main area for the air-conditioning component to perform code scanning operations. The positioning mechanism 20 is arranged on the frame 10 and is located on one side of the code scanning area 101. The positioning mechanism 20 can fix the position of the air-conditioning component transported to the code scanning area 101, so that the air-conditioning component remains stationary in the code scanning area 101. The positioning mechanism 20 can specifically fix the air-conditioning component in the code scanning area 101 by a stopper, or can also fix the air-conditioning component in the code scanning area 101 by a clamping method. The scanning mechanism 30 is arranged adjacent to the scanning area 101 on the upper side of the rack 10. When the air-conditioning component is in the scanning area 101 on the upper side of the rack 10, the scanning mechanism 30 can scan the barcode on the air-conditioning component in the scanning area 101. When the scanning mechanism 30 scans the barcode, the barcode needs to remain still to ensure that the scanning mechanism 30 can scan and enter it. The entire automatic scanning device uses PLC as a controller, and controls the operation of the assembly line 200, the positioning mechanism 20 and the scanning mechanism 30 by programming the PLC. The production line of the previous production process places the air-conditioning component on the assembly line 200, and the assembly line 200 transports the air-conditioning component to the scanning area 101 on the upper side of the rack 10. A photoelectric sensor is installed next to the scanning area 101 of the rack 10 and is connected to the PLC system to obtain the position information of the air-conditioning component. The PLC system can determine whether the air-conditioning component has reached the scanning area 101 by the signal sent back by the photoelectric sensor.When the photoelectric sensor detects that the air-conditioning component has arrived at the code scanning area 101 on the upper side of the frame 10, the PLC system controls the positioning mechanism 20 to position the air-conditioning component in the code scanning area 101. The positioning mechanism 20 fixes the position of the air-conditioning component in the code scanning area 101, so that the air-conditioning component cannot be transported further down by the assembly line 200. Then the PLC system controls the scanning mechanism 30 to scan the barcode on the air-conditioning component in the code scanning area 101, and enters the information of the barcode on the air-conditioning component into the system. The scanning of the barcode on the air-conditioning component is completed. The information of the barcode on the air-conditioning component is entered into the system. The system can determine whether the air-conditioning component in the code scanning area 101 is a qualified product. When the air-conditioning component is determined to be a qualified product, the PLC system can control the positioning mechanism 20 to release the positioning of the air-conditioning component, so that the assembly line 200 continues to transport the air-conditioning component that has been scanned in the code scanning area 101 to the production line of the next process. At the same time, the air-conditioning component that has not been scanned before continues to be transported by the assembly line 200 to the code scanning area 101 for scanning. When the system determines that the air-conditioning component is an unqualified product, the positioning mechanism 20 always keeps the air-conditioning component positioned. A buzzer can be set to connect to the PLC system. When the system determines that the air-conditioning component is an unqualified product, an alarm is sounded through the buzzer to instruct the operator to remove the unqualified product from the scanning area 101 so as to further analyze and locate the problem of the unqualified product.

[0033] The automatic barcode scanning device of this embodiment is arranged in conjunction with the assembly line. The frame defines a barcode scanning area on the upper side of the assembly line. The position of the air-conditioning component is fixed in the barcode scanning area by a positioning mechanism. The scanning mechanism is arranged adjacent to the barcode scanning area so that the scanning mechanism scans the barcode on the air-conditioning component in the barcode scanning area, thereby realizing automatic barcode scanning of the air-conditioning component, reducing manual labor, improving barcode scanning efficiency, and effectively improving product production efficiency.

[0034] In one embodiment, referring to Figures 3 to 7, the scanning mechanism 30 includes a mounting portion 31 and at least one barcode scanner 32. The mounting portion 31 is arranged above the frame 10 and on a side above the barcode scanning area 101. The barcode scanner 32 is arranged on the mounting portion 31. In a specific implementation, the scanning mechanism 30 includes a mounting portion 31 and a barcode scanner 32. The barcode scanner 32 is an electronic device that is specifically used to scan barcodes and read barcode information. Since the barcode scanner 32 needs to be in a position where it can clearly identify the barcode when scanning, the scanning range of the barcode scanner 32 needs to cover the entire barcode scanning area 101. Here, the mounting portion 31 is used as a structure for mounting the barcode scanner 32. The mounting portion 31 is arranged above the frame 10 as a whole, and the mounting portion 31 is located above the barcode scanning area 101. On one side, the barcode scanner 32 is installed on the installation part 31, so that the barcode scanner 32 is located on one side above the barcode scanning area 101 as a whole. The number of the barcode scanner 32 is at least one, and specifically, multiple barcode scanners 32 can be set so that the multiple barcode scanners 32 are located on one side of the barcode scanning area 101. The scanning range of the barcode scanner 32 can cover the entire barcode scanning area 101. Even if the position of the barcode on the air-conditioning component is slightly offset, the barcode scanner 32 can also scan and read the barcode information normally, and the reliability of automatic scanning is higher.

[0035] Further, refer to Figures 3 to 7The mounting portion 31 includes a transverse connection portion 310 and a vertical connection portion 311. The transverse connection portion 310 is horizontally extended along the transportation direction of the assembly line 200 above the rack 10 and is arranged on one side above the code scanning area 101. The vertical connection portion 311 is vertically extended along the vertical direction above the rack 10 and is arranged on one side above the code scanning area 101. The code scanner 32 is movably arranged on the transverse connection portion 310 and the vertical connection portion 311, respectively. In a specific implementation, a plurality of code scanners 32 are provided. The mounting portion 31 of the scanning mechanism 30 is composed of a transverse connection portion 310 and a vertical connection portion 311. The transverse connection portion 310 and the vertical connection portion 311 are both equipped with the code scanner 32, and the code scanner 32 is movable relative to the transverse connection portion 310 and the vertical connection portion 311. The transverse connection part 310 is horizontally extended along the transportation direction of the assembly line 200 above the rack 10 and is arranged on one side above the code scanning area 101. The code scanner 32 installed on the transverse connection part 310 can move along the axial direction of the transverse connection part 310 to adjust its position in the horizontal direction. The code scanner 32 has a horizontally adjustable distance relative to the code scanning area 101. The vertical connection part 311 is extended along the vertical direction above the rack 10 and is arranged on one side above the code scanning area 101. The code scanner 32 installed on the vertical connection part 311 can move along the axial direction of the vertical connection part 311 to adjust its height in the vertical direction. The code scanner 32 also has a vertically adjustable distance relative to the code scanning area 101, so that the code scanner 32 has a wider scanning range as a whole, and the reliability of automatic code scanning is improved.

[0036] Furthermore, refer to Figure 7 There are two vertical connection parts 311 , and the two vertical connection parts 311 are spaced apart in the transport direction of the assembly line 200 , and the transverse connection part 310 is connected between the two vertical connection parts 311 . In a specific implementation, two vertical connection parts 311 of the scanning mechanism 30 are arranged, and the two vertical connection parts 311 are arranged at intervals in the transport direction of the assembly line 200, and both are located on one side above the code scanning area 101. The transverse connection part 310 is arranged between the two vertical connection parts 311, and the opposite ends of the transverse connection part 310 are respectively connected and fixed to the two vertical connection parts 311. Each vertical connection part 311 is installed with at least one code scanner 32, and at least one code scanner 32 is also installed on the transverse connection part 310, for a total of at least three code scanners 32. On the whole, the code scanners 32 installed on the two vertical connection parts 311 and the code scanners 32 installed on the transverse connection part 310 together form a triangular code scanner 32 array, which has a wide scanning range, a higher accuracy in obtaining the barcodes on the air-conditioning components in the code scanning area 101, and a higher reliability in automatic scanning.

[0037] In one embodiment, referring to Figures 2 to 4 The positioning mechanism 20 includes a lifting module 21 and a stopper 22. The lifting module 21 is arranged on the frame 10 and is located below the code scanning area 101. The stopper 22 is transversely arranged on one side of the code scanning area 101 in the transportation direction of the assembly line 200. The lifting module 21 is connected to the stopper 22, wherein the lifting module 21 is used to drive the stopper 22 to move up and down in the vertical direction so that the stopper 22 blocks the air-conditioning component in the transportation direction of the assembly line 200. In a specific implementation, the positioning mechanism 20 includes a lifting module 21 and a stopper 22. The lifting module 21 is arranged at a position where the frame 10 is below the code scanning area 101. The stopper 22 is designed to be a straight columnar structure. The stopper 22 is laterally arranged on one side of the code scanning area 101 in the transportation direction of the assembly line 200, that is, the stopper 22 is close to the end edge of the code scanning area 101. The length of the stopper 22 is designed to completely withstand the length of the entire air-conditioning component. The lifting module 21 is connected to the stopper 22 below the code scanning area 101. Group 21 can drive the stopper 22 to move up and down in the vertical direction. Under normal circumstances, the lifting module 21 drives the stopper 22 to be in an ascending state, so that the stopper 22 blocks the air-conditioning component in the code scanning area 101. When the lifting module 21 drives the stopper 22 to descend in the vertical direction, the descending stopper 22 is below the code scanning area 101, and the top position of the top of the stopper 22 is lower than the plane on the upper side of the assembly line 200. The air-conditioning component is no longer blocked by the stopper 22 in the code scanning area 101, and the air-conditioning component is continued to be transported downward by the assembly line 200. During the specific scanning process, the PLC system controls the lifting module 21 to drive the stopper 22 to be in the state after the lifting, that is, the stopper 22 is in the scanning area 101. After the assembly line 200 transports the air-conditioning component to the scanning area 101, the air-conditioning component is blocked by the stopper 22 and stays in the scanning area 101 to remain relatively still. Then the PLC system controls the scanning mechanism 30 to scan the barcode on the air-conditioning component in the scanning area 101. The system determines whether the air-conditioning component is qualified based on the information of the read barcode. If the system determines that the air-conditioning component is unqualified, the PLC system will not control the lifting module 21 to drive the stopper 22 to descend, but keep the stopper 22 in the scanning area. The air-conditioning component continues to be blocked in the raised state, and the system prompts the operator to remove the unqualified product through a buzzer alarm or a light, so that the next air-conditioning component can continue to enter the code scanning area 101; if the system determines that the air-conditioning component in the code scanning area 101 is qualified, the PLC system controls the lifting module 21 to drive the stopper 22 to descend, so that the assembly line 200 continues to transport the qualified product downward. After the product leaves the code scanning area 101, the PLC system controls the lifting module 21 to drive the stopper 22 to rise, so that the stopper 22 continues to block the next air-conditioning component in the raised state, and the above process is repeated to achieve efficient production.

[0038] Further, refer to Figure 4 , the lifting module 21 includes a telescopic drive member 210, the telescopic drive member 210 is arranged on the frame 10 and is located below the code scanning area 101, and the bottom end of the stopper 22 is connected to the telescopic drive member 210, wherein the telescopic drive member 210 is used to perform telescopic movement in the vertical direction to drive the stopper 22 to move up and down in the vertical direction. In the specific implementation, the lifting module 21 is composed of a telescopic drive member 210, and the telescopic drive member 210 is arranged at a position where the frame 10 is below the code scanning area 101. The telescopic drive member 210 is specifically a telescopic cylinder, which is pneumatically controlled to achieve telescopic movement. The driving shaft of the telescopic drive member 210 is connected to the bottom end of the stopper 22. Under the control of the PLC system, the driving shaft of the telescopic drive member 210 can perform telescopic movement in the vertical direction, driving the stopper 22 to move up and down in the vertical direction, thereby realizing the lifting and lowering of the stopper 22 in the code scanning area 101.

[0039] In one embodiment, referring to Figure 4 , the positioning mechanism 20 further includes a lifting guide module 23, the lifting guide module 23 is arranged on the frame 10 and is located below the code scanning area 101, and the lifting guide module 23 and the lifting module 21 are arranged horizontally spaced apart, wherein the lifting guide module 23 is used to guide the stopper 22 to move in the vertical direction. In a specific implementation, the positioning mechanism 20 further includes a lifting guide module 23, the lifting guide module 23 is arranged at a position below the code scanning area 101 of the frame 10 like the lifting module 21, and the lifting guide module 23 and the lifting module 21 are arranged horizontally spaced apart below the code scanning area 101. Since the lifting module 21 drives the stopper 22 to move up and down in the vertical direction, the stopper 22 needs to maintain a stable posture during the lifting and moving process. Here, the lifting guide module 23 guides the stopper 22 to move in the vertical direction beside the lifting module 21, so that the stopper 22 can maintain a stable movement posture to prevent the stopper 22 from swinging or tilting horizontally during the lifting process and deviating from the preset blocking position in the code scanning area 101 to affect the blocking of the air-conditioning components.

[0040] Further, refer to Figure 4The lifting guide module 23 includes a positioning shaft 231 and a positioning sleeve 230. The positioning sleeve 230 is vertically fixed to the frame 10 and is horizontally spaced apart from the lifting module 21. The positioning shaft 231 is vertically fixed to the bottom of the stopper 22 in the vertical direction, and the positioning shaft 231 can be movably inserted into the positioning sleeve 230. In the specific implementation, the lifting guide module 23 is composed of a positioning shaft 231 and a positioning sleeve 230. The positioning sleeve 230 is a hollow sleeve structure as a whole, and the positioning shaft 231 is a circular shaft structure. The diameter of the positioning shaft 231 is adapted to the inner diameter of the positioning sleeve 230. The positioning sleeve 230 is vertically arranged and fixed on the frame 10 below the code scanning area 101 as a whole, and maintains a certain interval with the lifting module 21 in the horizontal direction. The positioning shaft 231 is vertically arranged as a whole, and the top end of the positioning shaft 231 is vertically fixed to the bottom of the stopper 22, and the positioning shaft 231 is movably inserted into the positioning sleeve 230 as a whole. The positioning shaft 231 can only move along the axial direction of the positioning sleeve 230, thereby guiding the stopper 22 to move stably in the vertical direction. When the lifting module 21 drives the stopper 22 to lift, the stopper 22 can move more smoothly, and the stopper 22 will not have the problem of horizontal swing or tilt, thereby improving the reliability of positioning the air-conditioning components.

[0041] In one embodiment, referring to Figures 1 to 4 The automatic code scanning device further includes a guide mechanism 40, which is disposed above the rack 10 and located on one side of the transportation direction of the assembly line 200 and adjacent to the code scanning area 101, wherein the guide mechanism 40 is used to guide the air-conditioning components transported by the assembly line 200 to move toward the code scanning area 101. In a specific implementation, the air-conditioning components are placed on the assembly line 200 in the previous production process, and each air-conditioning component is placed at a different position on the assembly line 200. Some air-conditioning components are located in the center of the assembly line 200, while some air-conditioning components may be closer to the edge of the assembly line 200. When the assembly line 200 transports the air-conditioning components to the automatic code scanning device, the air-conditioning components need to be completely located in the code scanning area 101. Therefore, the automatic code scanning device is provided with a guide mechanism 40 to adjust the position of the air-conditioning components. The guide mechanism 40 is arranged as a whole above the rack 10 at the edge of one side in the transport direction of the assembly line 200. The guide mechanism 40 is adjacent to the code scanning area 101 as a whole. In the process of the assembly line 200 transporting the air-conditioning components toward the code scanning area 101, the guide mechanism 40 can guide the air-conditioning components at the edge of the assembly line 200 to offset toward the center of the assembly line 200, so that the air-conditioning components transported by the assembly line 200 can move correctly toward the code scanning area 101 as a whole. Each air-conditioning component can enter the scanning position in the code scanning area 101 as a whole, and the scanning mechanism 30 can scan the barcode on the air-conditioning component.

[0042] Further, refer to Figure 1 and Figure 2 , the guide mechanism 40 includes a first guide member 41 and a second guide member 42. The second guide member 42 is extended along the transport direction of the assembly line 200 and is arranged on one side of the code scanning area 101. The first guide member 41 is connected to the second guide member 42 and extends outwardly in a horizontal direction away from the assembly line 200. In a specific implementation, the guide mechanism 40 is composed of a first guide member 41 and a second guide member 42. The first guide member 41 and the second guide member 42 are both in the same horizontal plane. The second guide member 42 is extended along the transport direction of the assembly line 200 and is arranged on one side edge of the code scanning area 101. The whole is parallel to the assembly line 200, and its length covers the width of the code scanning area 101 in the transport direction of the assembly line 200. The first guide member 41 is connected to the end of the second guide member 42. The first guide member 41 as a whole extends outwardly in a direction away from the assembly line 200. When the assembly line 200 transports the air-conditioning components toward the code scanning area 101, the first guide member 41 is connected to the end of the second guide member 42. The first guide member 41 as a whole extends outwardly in a direction away from the assembly line 200. During the movement, the air-conditioning component first contacts the first guide member 41. The first guide member 41, which is inclined outward relative to the assembly line 200, guides the air-conditioning component in the moving state, so that the air-conditioning component is passively moved toward the center position on the assembly line 200 along with the transportation of the assembly line 200. The air-conditioning component gradually moves toward the code scanning area 101, and then the air-conditioning component enters the code scanning area 101 and is guided and aligned by the vertical guide member parallel to the operation direction of the assembly line 200. The air-conditioning component enters the scanning point in the code scanning area 101 with a normal placement posture, which facilitates the subsequent scanning operation of the scanning mechanism 30.

[0043] In one embodiment, a control method for an automatic code scanning device is provided. Figure 8 , Figure 8 A flow chart of a control method for an automatic code scanning device provided by an embodiment of the present utility model is shown as follows: Figure 8 As shown, the method includes the following steps S110-130.

[0044] S110, if it is detected that there is an air-conditioning component in the code scanning area, control the positioning mechanism to locate the air-conditioning component, and control the scanning mechanism to scan the barcode of the air-conditioning component to obtain production data;

[0045] In the specific implementation, the entire automatic code scanning device is controlled and operated by the PLC system. A photoelectric sensor is installed next to the code scanning area on the rack and connected to the PLC system to obtain the position information of the air-conditioning component. The PLC system can determine whether there is an air-conditioning component in the code scanning area through the signal sent back by the photoelectric sensor. When the air-conditioning component is transported to the code scanning area by the assembly line, the photoelectric sensor detects the air-conditioning component and outputs a signal to the PLC system. The PLC system controls the positioning mechanism to position the air-conditioning component in the code scanning area, so that the air-conditioning component cannot be transported further down the assembly line. The corresponding points of the air-conditioning component in the code scanning area remain relatively static. The PLC system then controls the scanning mechanism to scan the barcode on the air-conditioning component in the code scanning area, specifically through the barcode scanner. After the scanning is successful, the information of the barcode on the air-conditioning component is entered into the system for analysis to obtain production data. The production data is the data recorded by the air-conditioning component in each previous production process. The production data can reflect the production status of the air-conditioning component in each previous production process.

[0046] S120: Determine whether the air conditioning component is qualified based on the comparison between the production data and the preset index.

[0047] In a specific implementation, after the scanning mechanism scans the barcode on the air-conditioning component and enters it into the system, the system will parse the information of the barcode and obtain the production data recorded in the production process of the air-conditioning component corresponding to the barcode before the automatic scanning device. The system compares the production data obtained by parsing with the preset indicators. The preset indicators are indicators for measuring the correctness of the production data of each production process. The preset indicators include the data indicators of each production process. The system uses the preset indicators as the judgment standard to judge whether the air-conditioning component is a qualified product. For example, when the system parses the barcode on a certain air-conditioning component to obtain production data, and the production data of a previous process does not meet the indicator value in the preset indicators, it means that the air-conditioning component did not meet the standards in the previous production process, and the system can judge that the air-conditioning component is an unqualified product; and when the system parses the barcode on a certain air-conditioning component to obtain production data, and the production data of the previous processes all meet the indicator values ​​in the preset indicators, it means that the air-conditioning component has all met the standards in the previous production processes, and the system can judge that the air-conditioning component is a qualified product.

[0048] S130: If the air-conditioning component is qualified, control the positioning mechanism to release the positioning of the air-conditioning component.

[0049] In the specific implementation, after the system determines that the air-conditioning component is a qualified product, the PLC system controls the positioning mechanism to release the positioning of the air-conditioning component, so that the air-conditioning component is continuously transported to the next production process by the assembly line, and the air-conditioning component that has not been scanned continues to be transported to the code scanning area by the assembly line. In the case where the system determines that the air-conditioning component is an unqualified product, the PLC system controls the positioning mechanism to always keep the air-conditioning component in the state of positioning. A buzzer can be set to connect to the PLC system. When the system determines that the air-conditioning component is an unqualified product, the buzzer will sound an alarm, instructing the operator to remove the unqualified product from the code scanning area, so as to further analyze and locate the problem of the unqualified product.

[0050] The control method of the automatic barcode scanning device of the present embodiment controls the positioning mechanism to position the air-conditioning component by detecting the presence of the air-conditioning component in the barcode scanning area, and controls the scanning mechanism to scan the barcode of the air-conditioning component to obtain production data; determines whether the air-conditioning component is qualified based on the comparison between the production data and the preset indicators, and controls the positioning mechanism to release the positioning of the air-conditioning component when the air-conditioning component is determined to be qualified, thereby effectively realizing the automatic barcode scanning process of the product, reducing manual labor, and improving the production efficiency of the product.

[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
