Description

Technical Field

[0001] This application belongs to the field of circuit board testing technology, and in particular relates to a barcode scanning device and circuit board testing equipment. Background Technology

[0002] In the fields of automated production and intelligent manufacturing, reading identification codes (such as QR codes and barcodes) on circuit boards using barcode scanning devices is a crucial step in achieving product traceability, quality control, and process tracking. Currently, mainstream barcode scanning devices typically employ an integrated design where the barcode scanner and supplementary lighting are fixedly connected. This means the positions and angles of the supplementary lighting and the barcode scanner are synchronized; as the barcode scanner aligns with the identification code, the supplementary lighting simultaneously points to that area, aiming to enhance the clarity of the identification code through supplementary illumination.

[0003] However, in actual circuit board scanning scenarios, this integrated structure has significant limitations. Circuit boards, as carriers of precision electronic components, often have densely packed solder joints, capacitors, resistors, and other components on their surface. The printing position of the identification codes is often limited by space, potentially located in component gaps, edges, corners, or uneven areas. Current barcode scanners typically have fixed supplementary lighting, but different circuit boards have different identification code specifications (such as size, printing method, and color), requiring varying light angles and intensities. Fixed, linked supplementary lighting modes cannot flexibly adapt to these diverse scenarios, leading to unstable scanning efficiency and impacting the continuity of automated production. Utility Model Content

[0004] The purpose of this application is to provide a barcode scanning device and a circuit board testing equipment, which aims to solve the technical problem that the supplementary lighting mode of existing barcode scanning devices cannot flexibly adapt to different scenarios.

[0005] The embodiments of this application are implemented as follows: Firstly, a barcode scanning device is provided for scanning identification codes on a circuit board, wherein the identification codes are located in a designated area of ​​the circuit board, and the barcode scanning device includes a barcode scanning mechanism and a supplementary light mechanism.

[0006] The scanning mechanism is used to scan the identification code;

[0007] The supplementary lighting mechanism includes a supplementary lighting adjustment component and at least one supplementary light. The supplementary light is connected to the supplementary lighting adjustment component, and the supplementary lighting adjustment component can adjust the position and / or angle of the supplementary light so that the supplementary light illuminates the set area.

[0008] One possible scenario for the first aspect is that the scanning mechanism includes a barcode scanner and a barcode adjustment component, wherein the barcode scanner is connected to the barcode adjustment component and is used to scan in a first direction, and the barcode adjustment component is used to adjust the position of the barcode scanner.

[0009] One possible scenario for the first aspect is that the barcode adjustment component includes a first barcode moving part and a second barcode moving part, the second barcode moving part being movably connected to the first barcode moving part along a first direction, the barcode scanner being movably connected to the first barcode moving part along a second direction, the first barcode moving part being capable of reciprocating along a third direction, the second direction being perpendicular to the first direction, and the third direction being perpendicular to both the first and second directions.

[0010] One possible scenario for the first aspect is that the supplementary lighting adjustment component includes a first supplementary lighting moving member and a second supplementary lighting moving member, the second supplementary lighting moving member being movably connected to the first supplementary lighting moving member along a fourth direction and a fifth direction, the first supplementary lighting moving member being capable of reciprocating along a sixth direction, the supplementary light being connected to the second supplementary lighting moving member, the fifth direction being perpendicular to the fourth direction, and the sixth direction being perpendicular to the fourth direction and the fifth direction.

[0011] One possible scenario for the first aspect is that the second supplementary lighting moving component includes a supplementary lighting adjusting rod and a supplementary lighting adjusting plate. The supplementary lighting adjusting rod has multiple mounting portions, which are arranged along the fifth direction. One mounting portion is movably connected to the first supplementary lighting moving component along the fourth direction. The supplementary lighting adjusting plate is movably connected to one of the mounting portions along the fifth direction. The supplementary light is connected to the supplementary lighting adjusting plate.

[0012] One possible scenario for the first aspect is that there are two supplementary lights, which are arranged at intervals along the fourth direction and form a clearance space between them. The clearance space is opposite to the barcode scanner in the fifth direction, and the barcode scanner scans the identification code in the fifth direction.

[0013] One possible scenario for the first aspect is that the fill light is rotatably connected to the fill light adjustment member.

[0014] One possible scenario for the first aspect is that the scanning device further includes a mounting base, and both the scanning mechanism and the supplementary lighting mechanism are movably connected to the mounting base.

[0015] In a second aspect, a circuit board inspection device is provided, including a circuit board conveying device and a barcode scanning device as described in any of the above embodiments. The circuit board conveying device is used to convey the circuit board to a destination position, the barcode scanning device is used to scan the identification code on the circuit board located at the destination position, and the supplementary light is used to illuminate the designated area of ​​the circuit board located at the destination position.

[0016] One possible scenario for the second aspect is that the circuit board has a coding surface with an identification code, the circuit board conveying device includes a flipping machine, the flipping machine is used to convey the circuit board with the coding surface facing the first direction to the endpoint position, and such that the coding surface of the circuit board at the endpoint position faces away from the first direction, the scanning device is disposed on the side of the endpoint position facing away from the first direction, and the barcode scanner is capable of scanning the identification code facing the first direction.

[0017] The technical advantages of this application embodiment compared to the prior art are as follows: This scanning device, by setting up an independent supplementary lighting mechanism, utilizes supplementary lighting adjustment components to flexibly adjust the position and / or angle of the supplementary light, enabling precise adaptation to the different lighting requirements of the identification codes on the circuit board due to space limitations (such as being located between components, at edges or corners) and specification differences (such as size, printing method, and color). This design effectively eliminates interference such as reflections and shadows in the fixed linkage supplementary lighting mode, ensuring that the supplementary light illuminates the designated area where the identification code is located at the optimal angle and intensity. This significantly improves the recognition efficiency and stability of the identification codes by the scanning mechanism, reduces scanning failures or misjudgments caused by lighting problems, thereby ensuring the continuity of the automated production process of the circuit board and reducing the cost of manual intervention.

[0023] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0024] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0027] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0029] This application provides a circuit board testing device. The testing process of the circuit board testing device includes the following steps in sequence: board loading, inspection, board flipping, board separation, and board unloading.

[0030] The loading process involves using automated conveyor systems (such as conveyor belts or robotic arms) to neatly feed the circuit boards to be inspected into the inspection equipment according to a preset direction and spacing. The inspection process can be Automatic Optical Inspection (AOI), which uses automated optical inspection equipment to comprehensively scan the surface of the circuit board. A high-definition camera captures detailed images of solder joints, components, and circuitry, and compares them with a standard template to automatically identify defects such as cold solder joints, missing components, short circuits, and stains. The location and type of defects are marked in real time, providing data support for subsequent processing. This inspection can be performed on one or both sides of the circuit board, and an identification code is marked on the circuit board after inspection. The flipping process involves flipping the circuit board at a set angle (usually 180°). The separating process involves using tools, lasers, or punching to divide the circuit board into independent circuit board units along a preset separating line. The unloading process involves sending the qualified and unqualified circuit boards to their respective material frames or subsequent processing areas, completing the closed loop of the entire inspection line.

[0031] The identification codes on the circuit boards are key identifiers used for product traceability, production management, and quality control. These codes include, but are not limited to, barcodes (such as Universal Product Code (UPC) and European Article Numbering (EAN) codes), QR codes (such as Quick Response Code (QR) and Data Matrix Code), and Radio Frequency Identification (RFID) tags. The identification codes store processing information. This processing information may include basic product information (such as specifications), production-related information (such as production date and batch number), traceability and tracking information (such as key processes in the production process and the manufacturer), and testing and verification information (such as the testing process and test results).

[0032] The circuit board testing equipment includes a circuit board conveying device, which is used to convey circuit boards in the above-mentioned testing process and can convey the circuit boards to the end position during the conveying process or at the end of the conveying process.

[0033] Please see Figure 1 It is understandable that the circuit board conveying device includes a flipper 80, which is the main device in the flipping process. It is capable of performing material flipping operations. Its core function is to stably flip materials such as boards, rolls, and boxes at preset angles (commonly 90° or 180°) using mechanical structures (such as flipping frames, clamping devices, and drive systems). This allows for both material flipping (to meet the needs of double-sided processing, printing, coating, etc.) and changing the material's conveying direction or posture (such as changing from horizontal to vertical placement to adapt to the feeding requirements of subsequent processes). The circuit boards 90 on the flipper 80 are all marked with identification codes. Each circuit board 90 has a marking surface on which the identification code is located.

[0034] In this embodiment, the circuit board 90 is first placed on the flipping machine 80 with the coding surface facing the first direction. At this time, the circuit board 90 is in the starting position. The flipping machine 80 can transport and flip the circuit board 90 at the starting position until it is transported to the destination position. At this time, the coding surface of the circuit board 90 at the destination position faces away from the first direction. For ease of understanding, the following embodiment uses upward as the first direction as an example. Based on this, the circuit board 90 is placed on the flipping machine 80 with the coding surface facing upward. The flipping machine 80 can transport the circuit board 90 to the destination position and flip the circuit board 90 so that the coding surface faces downward.

[0035] In the illustrated embodiment, the flipping machine 80 includes a rotating shaft 81 and multiple flipping plates 82. The multiple flipping plates 82 are sequentially connected to the rotating shaft 81 around its circumference and are arranged in a divergent pattern. The rotation axis of the rotating shaft 81 extends horizontally. After the circuit board 90 is marked with an identification code, it can be placed on the flipping plate 82 located at the starting position by a robotic arm. This flipping plate 82 is designated as the first flipping plate 82, and the adjacent flipping plate 82 in the rotation direction of this flipping plate 82 is designated as the second flipping plate 82. The angle between the first flipping plate 82 and the second flipping plate 82 can be α. The first flipping plate 82 located at the starting position is in a horizontal state, that is, the angle between the first flipping plate 82 at the starting position and the horizontal plane is zero. The marking surface of the circuit board 90 faces away from the first flipping plate 82 and towards the second flipping plate 82. The rotating shaft 81 causes the first and second flip plates 82 to rotate upwards. The first flip plate 82 drives the circuit board 90 to rotate. When the rotation angle of the first flip plate 82 is greater than 90°, the circuit board 90 begins to move towards the second flip plate 82 under the action of gravity until it abuts against the second flip plate 82. At this point, the marking plate surface is in contact with the second flip plate 82. When the rotation angle of the first flip plate 82 is β, the second flip plate 82 is in a horizontal state, that is, the angle between the second flip plate 82 and the horizontal plane is zero, and the sum of β and α equals 180°. At this time, the second flip plate 82 is at its final position, and the circuit board 90 abuts against the second flip plate 82 under the action of gravity, while the second flip plate 82 avoids the marking code on the marking plate surface. Afterwards, the circuit board 90 can be removed from the second flip plate 82 by a robotic arm for further processing.

[0036] During the rotation of the flipping machine 80, a circuit board 90 can be placed between any two flipping plates 82 located above the rotating shaft 81. Therefore, the flipping machine 80 can perform continuous flipping operations on multiple circuit boards 90 sequentially. During this process, the operator can remove previously identified abnormal circuit boards 90 for re-inspection or processing. However, if the removed abnormal circuit boards 90 are not returned to their original positions in time before entering the next process, the actual arrangement order of the subsequent circuit boards 90 will deviate from the theoretical order. This disordered order will continue into subsequent processes, making it impossible for the processing and inspection data of each circuit board 90 to accurately correspond to its own information, thereby affecting the normal traceability and data management of the production process.

[0037] Based on this, the circuit board conveying device also includes a barcode scanning device, which can scan the identification code on the circuit board 90 to obtain the processing information of the circuit board 90. The barcode scanning device is located on the side opposite to the first direction at the end position, and the barcode scanning device can scan the identification code facing the first direction. Specifically, when the circuit board 90 is conveyed to the end position by the flipping machine, the coding plate surface of the circuit board 90 faces downward, the barcode scanning device is located below the circuit board 90, and the barcode scanning device can scan the identification code on the coding plate surface upward.

[0038] Circuit boards, as carriers of precision electronic components, often have densely packed solder joints, capacitors, resistors, and other components on their surfaces. The printing position of identification codes is often limited by space, and may be located in component gaps, edges, corners, or uneven areas. Current barcode scanners are generally equipped with fixed supplementary lights, but the specifications of identification codes on different circuit boards (such as size, printing method, and color) vary, and the requirements for light angle and intensity differ. Fixed and linked supplementary lighting modes cannot flexibly adapt to these differentiated scenarios, resulting in unstable scanning efficiency and affecting the continuity of automated production.

[0039] To resolve the above issues, please refer to [link / reference]. Figure 1 The barcode scanning device 100 in this embodiment includes a scanning mechanism 10 and a supplementary lighting mechanism 20. The scanning mechanism 10 scans the identification code on the circuit board 90 located at the endpoint, and the supplementary lighting mechanism 20 emits light to illuminate a designated area on the circuit board 90 located at the endpoint. The identification code is located on this designated area. It should be noted that the orthographic projection of the identification code on the circuit board 90 may coincide with the designated area or may be located within the designated area, i.e., the area of ​​the designated area is larger than the area of ​​the orthographic projection of the identification code on the circuit board 90.

[0040] Specifically, the supplementary lighting mechanism 20 includes a supplementary lighting adjustment component 22 and at least one supplementary light 21. The supplementary light 21 emits light and is connected to the supplementary lighting adjustment component 22. The supplementary lighting adjustment component 22 can be installed independently of other structures or mounted on other structures; this is not limited here. The supplementary lighting adjustment component 22 can adjust the position and / or angle of the supplementary light 21 so that the supplementary light 21 illuminates a designated area. That is, the supplementary lighting adjustment component 22 can translate the supplementary light 21, rotate the supplementary light 21, or perform both translation and rotation simultaneously.

[0041] It should be noted that the supplementary lighting mechanism 20 needs to avoid the scanning mechanism 10 in the scanning direction. In this embodiment, the scanning direction of the scanning mechanism 10 is the first direction, that is, upward. The supplementary lighting mechanism 20 avoids the scanning path of the scanning mechanism 10 in the vertical direction, thereby avoiding obstruction of the scanning field of view of the scanning mechanism 10.

[0042] The barcode scanning device 100, by setting up an independent supplementary lighting mechanism 20 and using the supplementary lighting adjustment component 22 to flexibly adjust the position and / or angle of the supplementary light 21, can accurately adapt to the different lighting requirements of the identification codes on the circuit board 90 due to space limitations (such as being located between components, at edges or corners) and specification differences (such as size, printing method, and color). This design can effectively eliminate interference such as reflections and shadows in the fixed linkage supplementary lighting mode, ensuring that the supplementary light 21 illuminates the set area where the identification code is located at the optimal angle and intensity, significantly improving the recognition efficiency and stability of the identification codes by the scanning mechanism 10, reducing scanning failures or misjudgments caused by lighting problems, thereby ensuring the continuity of the automated production process of the circuit board 90 and reducing the cost of manual intervention.

[0043] It is understood that the scanning mechanism 10 includes a barcode scanner 11 and a barcode adjustment component 12. The barcode scanner 11 is connected to the barcode adjustment component 12 and is used for scanning in a first direction. The barcode adjustment component 12 is used to adjust the position of the barcode scanner 11, that is, the barcode adjustment component 12 can drive the barcode scanner 11 to translate to change the scanning position. The barcode adjustment component 12, together with the supplementary lighting mechanism 20, independently adjusts the position and / or angle of the supplementary light 21, forming a dual flexible adjustment mechanism. On the one hand, the barcode scanner 11 can accurately align with the identification codes at different positions by translation, adapting to the scanning position requirements caused by the layout differences of the identification codes on the circuit board 90 (such as the identification codes being distributed in different areas such as component gaps, edges, and corners); on the other hand, the barcode adjustment component 12 can dynamically adjust the spatial position of the barcode scanner 11 according to the illumination direction of the supplementary light 21, and effectively prevent reflected light from directly entering the photosensitive element of the barcode scanner 11 by accurately avoiding the reflected light path formed by the supplementary light on the surface of the circuit board 90. This collaborative adjustment mechanism further optimizes the optical conditions of the scanning environment, reduces problems such as image overexposure and loss of code details caused by strong light interference, and enables the barcode scanner 11 to still capture clear identification code images stably in complex lighting scenarios, thereby greatly improving the recognition accuracy and providing a reliable foundation for subsequent data traceability and process control. It also further enhances the adaptability and stability of the equipment in high-density, multi-specification circuit board 90 production scenarios.

[0044] Please see Figure 2 Optionally, the barcode scanner 11 includes a base 111 and a scanning head 112. The scanning head 112 is mounted on the base 111 and may contain an optical imaging module. The base 111 may contain a decoding module. The optical imaging module is used to acquire image signals of the identification code, and the decoding module is used to convert the acquired image signals into digital signals to complete the parsing of the identification code. The base 111 is also provided with a data transmission interface for connecting to a host computer.

[0045] Please see Figure 2It is understood that the barcode adjustment component 12 includes a first barcode moving component 121 and a second barcode moving component 122. The second barcode moving component 122 is movably connected to the first barcode moving component 121 along a first direction, meaning the second barcode moving component 122 can reciprocate relative to the first barcode moving component 121 along the first direction. The barcode scanner 11 is movably connected to the first barcode moving component 121 along a second direction, meaning the barcode scanner 11 can reciprocate relative to the first barcode moving component 121 along the second direction. The barcode scanner 11 can be movably connected to the first barcode moving component 121 via a base 111. The first barcode moving component 121 can reciprocate along a third direction. This reciprocating movement of the first barcode moving component 121 along the third direction can be independent movement of the barcode adjustment component 12, or it can be movement of the barcode adjustment component 12 movably connected to other structural components; no limitation is made here. The second direction is perpendicular to the first direction, and the third direction is perpendicular to both the first and second directions. In this embodiment, since the first direction is upward, the second direction can be set to forward, and the third direction to the left.

[0046] The barcode scanner 11 can move flexibly in three directions—up and down, forward and backward, and left and right—with the help of the first scanning moving part 121 and the second scanning moving part 122. Up and down movement can precisely optimize the focusing effect on the identification code, ensuring clear imaging. Forward and backward movement and left and right movement can flexibly adjust the scanning position to adapt to the positional requirements of the identification codes on the circuit board 90 due to differences in layout (such as being located in different areas such as component gaps or edges and corners). This multi-directional adjustment mechanism, in conjunction with the independent adjustment of the supplementary lighting mechanism 20, can fully adapt to diverse identification code specifications and complex circuit board 90 environments, effectively improving the efficiency and accuracy of barcode scanning and reducing scanning failures caused by positional deviations or focusing problems, thus ensuring the smooth operation of automated production processes.

[0047] It should be noted that, to ensure positional stability during the scanning process, the barcode scanner 11 can be moved under the action of external force, and can remain at its current position after the external force is removed. The aforementioned external force includes, but is not limited to, external human force, mechanical force, electric driving force, magnetic force, etc.

[0048] The aforementioned active connection methods include, but are not limited to, sliding connections, rolling connections, and linear bearing connections.

[0049] Taking the above-mentioned active connections as sliding connections as an example, optionally, the first scanning moving part 121 has a first strip hole 1211, which extends along a first direction, i.e., the vertical direction, and penetrates the front and rear surfaces of the first scanning moving part 121. The second scanning moving part 122 has a first connecting hole 1221, and the second scanning moving part 122 is slidably connected to the first scanning moving part 121 by a first fastener that passes through the first connecting hole 1221 and the first strip hole 1211 in sequence.

[0050] The first fastener may include a first screw and a first nut that mates with the first screw. The first screw passes through the first connecting hole 1221 and the first strip hole 1211 and is slidably connected to the first strip hole 1211. The first nut is threadedly connected to the first screw, and the nut of the first screw, together with the first nut, can clamp the first scanning moving part 121 and the second scanning moving part 122. When it is necessary to adjust the vertical position of the second scanning moving part 122, the first nut can be loosened so that the first screw can be adjusted vertically along the first strip hole 1211. After the vertical position of the barcode scanner 11 is adjusted, the current position of the second scanning moving part 122 can be fixed by tightening the first nut to ensure that the barcode scanner 11 does not shift vertically. This structure retains the flexibility of vertical adjustment, which can quickly respond to the focusing needs of circuit boards of different thicknesses or different sizes of marking codes, and ensures the structural stability after adjustment through mechanical locking, avoiding position loosening due to factors such as equipment vibration, and further improving the reliability of the barcode scanner 11 in complex production environments. Alternatively, the second scanning moving part 122 may have a first strip-shaped hole 1211 extending vertically and penetrating both the front and rear surfaces of the second scanning moving part 122. The first scanning moving part 121 has a first connecting hole 1221, and the second scanning moving part 122 is slidably connected to the first scanning moving part 121 by a first fastener that passes sequentially through the first connecting hole 1221 and the first strip-shaped hole 1211. This is not a limitation.

[0051] As an alternative implementation, the first fastener can also be a first adjusting screw. The first adjusting screw can be rotatably connected to the first scanning moving part 121 and threadedly connected to the second scanning moving part 122. The first adjusting screw extends in the vertical direction, and the rotation axis rotatably connected to the first scanning moving part 121 extends in the vertical direction. When it is necessary to adjust the vertical position of the barcode scanner 11, the first adjusting screw can be turned, and the first scanning moving part 121 can be smoothly adjusted in the vertical direction by using the threaded transmission. This can accurately adapt to the focusing requirements of circuit boards of different thicknesses 90 or different sizes of marking codes, avoiding the positional movement that may occur when adjusting with a screw and nut structure. At the same time, the threaded connection has a self-locking characteristic, and the current position can be kept stable without additional locking operation after adjustment, effectively preventing positional deviation caused by equipment vibration, and further improving the reliability of the structure in complex production environments. Of course, the first adjusting screw can also be rotatably connected to the second scanning moving part 122 and threadedly connected to the first scanning moving part 121; this is not a limitation.

[0052] Optionally, the first scanning moving part 121 may also be provided with a first sliding groove, which extends vertically. The width of the groove opening is smaller than the width of the groove bottom. Both the width of the groove opening and the width of the groove bottom are horizontal. The second scanning moving part 122 is provided with a first slider, which matches the cross-section of the first sliding groove. In this way, the first sliding groove can restrict the first slider from disengaging from the first sliding groove in the front-back direction through the narrow groove opening. This structure retains the flexibility of vertical adjustment while strengthening the connection stability through mechanical limiting, avoiding structural loosening or disengagement caused by vibration or other factors during adjustment. Combined with adjustments in other directions, it further improves the adaptability and operational reliability of the scanning device 100 in complex production environments.

[0053] The first slider can be held in its current position by the friction between itself and the first groove. When the external force is greater than the friction, the vertical position of the barcode scanner 11 can be adjusted. Alternatively, the first groove can be provided on the second barcode scanner 122, and the first slider can be provided on the first barcode scanner 121. There is no limitation here.

[0054] As an alternative implementation, the second scanning moving part 122 can also limit its current position by setting an adjusting screw. The setting method of the adjusting screw is the same as that of the first adjusting screw in the first fastener in the previous embodiment, and will not be described in detail here.

[0055] Optionally, the first scanning moving part 121 has a second strip-shaped hole 1222, which extends along a second direction, i.e., the front-to-back direction, and penetrates the upper and lower surfaces of the first scanning moving part 121. The base 111 of the barcode scanner 11 may have a second connecting hole, and the barcode scanner 11 is movably connected to the first scanning moving part 121 by a second fastener that passes sequentially through the second connecting hole and the second strip-shaped hole 1222.

[0056] The second fastener may include a second screw and a second nut that mates with the second screw. The second screw passes through the second connecting hole and the second slotted hole 1222 and is slidably connected to the second slotted hole 1222. The second nut is threaded onto the second screw, and the nut of the second screw, together with the second nut, clamps the second scanning moving part 122 and the barcode scanner 11. When it is necessary to adjust the position of the barcode scanner 11 in the front-back direction, the second nut can be loosened so that the second screw can be adjusted along the second slotted hole 1222. After the position of the barcode scanner 11 is adjusted, the current position of the barcode scanner 11 can be fixed by tightening the second nut to ensure that the barcode scanner 11 does not shift in the front-back direction. This structure retains the flexibility of front-back adjustment and ensures the structural stability after adjustment through mechanical locking, avoiding loosening due to factors such as equipment vibration, and further improving the reliability of the barcode scanner 11 in complex production environments.

[0057] Of course, the base 111 of the barcode scanner 11 may have a second strip hole 1222, which extends in the front-back direction. The first barcode scanning moving part 121 may have a second connecting hole. The barcode scanner 11 may be slidably connected to the first barcode scanning moving part 121 by a second fastener that passes through the second connecting hole and the second strip hole 1222 in sequence. There are no restrictions here.

[0058] As an alternative implementation, the second fastener can also be a second adjusting screw. The second adjusting screw can be rotatably connected to the first scanning moving part 121 and threadedly connected to the base 111 of the barcode scanner 11. The second adjusting screw extends in the front-back direction, and the rotation axis rotatably connected to the first scanning moving part 121 extends in the front-back direction. When it is necessary to adjust the front-back position of the barcode scanner 11, the second adjusting screw can be turned to drive the barcode scanner 11 to smoothly achieve fine-tuning in the front-back direction through threaded transmission. This can accurately adapt to the different position requirements of circuit boards of different thicknesses 90 or different sizes of marking codes, avoiding positional movement that may occur when adjusting with a screw and nut structure. At the same time, the threaded connection has a self-locking characteristic, and the current position can be kept stable without additional locking operation after adjustment, effectively preventing positional deviation caused by equipment vibration, and further improving the reliability of the structure in complex production environments. Of course, the second adjusting screw can also be rotatably connected to the barcode scanner 11 and threadedly connected to the first scanning moving part 121; there is no limitation here.

[0059] Optionally, a second slide groove may also be provided on the first scanning moving part 121. The second slide groove extends in the front-to-back direction, and the width of the groove opening is smaller than the width of the groove bottom. The width directions of both the groove opening and the groove bottom are left-to-right. A second slider is provided on the barcode scanner 11, and the cross-section of the second slider matches that of the second slide groove. In this way, the second slide groove can restrict the second slider from disengaging from the slide groove in the front-to-back direction through the narrower groove opening. This structure retains the flexibility of vertical adjustment while strengthening the connection stability through mechanical limiting, avoiding structural loosening or disengagement caused by vibration or other factors during adjustment. Its synergistic effect with adjustments in other directions further improves the adaptability and operational reliability of the barcode scanner 100 in complex production environments.

[0060] The second slider can be held in its current position by the friction between itself and the second groove. When the external force is greater than the friction, the forward and backward position of the barcode scanner 11 can be adjusted. Of course, the second slider can also be set on the first barcode scanner moving part 121 and the second groove can be set on the barcode scanner 11. There is no limitation here.

[0061] As an alternative implementation, the barcode scanner 11 can also limit its current position by setting an adjusting screw. The setting method of the adjusting screw is the same as that of the second adjusting screw in the second fastener in the previous embodiment, and will not be described in detail here.

[0062] Please see Figure 2 It is understood that the supplementary lighting adjustment component 22 includes a first supplementary lighting moving component 221 and a second supplementary lighting moving component 222. The second supplementary lighting moving component 222 is movably connected to the first supplementary lighting moving component 221 along the fourth and fifth directions, meaning the second supplementary lighting moving component 222 can reciprocate relative to the first supplementary lighting moving component 221 along the fourth and fifth directions. The supplementary light 21 is connected to the second supplementary lighting moving component 222. The first supplementary lighting moving component 221 can reciprocate along the sixth direction. This reciprocating movement of the first supplementary lighting moving component 221 along the sixth direction can be an independent movement of the supplementary lighting adjustment component 22, or it can be a movement of the supplementary lighting adjustment component 22 movably connected to other structural components; no limitation is made here. The fifth direction is perpendicular to the fourth direction, and the sixth direction is perpendicular to both the fourth and fifth directions.

[0063] The supplementary lighting adjustment component 22, through the cooperation of the first supplementary lighting moving component 221 and the second supplementary lighting moving component 222, enables multi-dimensional adjustment of the supplementary light 21 in the fourth, fifth, and sixth directions (the three directions are perpendicular to each other). This multi-directional adjustment mechanism allows the supplementary light 21 to adapt to the lighting requirements of different scenarios based on the position (e.g., component gaps, edges and corners), specifications (size, printing method, color) of the marking codes on the circuit board 90 and the scanning path of the barcode scanner 11, effectively eliminating interference such as reflections and shadows. At the same time, the coordinated multi-directional adjustment of the supplementary lighting and the barcode scanner 11 can comprehensively optimize the scanning environment, further improve the efficiency and accuracy of barcode recognition, and enhance the adaptability of the equipment in complex production scenarios.

[0064] Among them, the fourth direction can be the same as the second direction, that is, the front-back direction; the fifth direction can be the same as the first direction, both being the up-down direction; and the sixth direction is the same as the second direction, both being the left-right direction. In this way, the supplementary light 21 can adapt to the supplementary lighting needs at different distances by moving the second supplementary light moving member 222 along the up-down direction. By moving the second supplementary light moving member 222 relative to the first supplementary light moving member 221 along the front-back direction and by moving the first supplementary light moving member 221 back and forth along the left-right direction, it can accurately adapt to the different distribution of the marking codes on the circuit board 90 in the plane (such as component gaps, edge corners).

[0065] It should be noted that, to ensure the stability of the light during the supplementary lighting process, the supplementary light 21 can be moved under the action of external force, and can remain in its current position after the external force is removed. The aforementioned external force includes, but is not limited to, external human force, mechanical force, electric driving force, magnetic force, etc.

[0066] The aforementioned active connection methods include, but are not limited to, sliding connections, rolling connections, and linear bearing connections.

[0067] Taking the sliding connection method mentioned above as an example, please refer to... Figure 2Optionally, the second supplementary lighting moving member 222 includes a supplementary lighting adjusting rod 2221 and a supplementary lighting adjusting plate 2222. The supplementary lighting adjusting rod 2221 has at least one mounting portion 22211. When multiple mounting portions 22211 are provided, the multiple mounting portions 22211 are arranged along the fifth direction, that is, along the vertical direction. One mounting portion 22211 is movably connected to the first supplementary lighting moving member 221 along the fourth direction, that is, the front-back direction. That is, the supplementary lighting adjusting rod 2221 can reciprocate relative to the first supplementary lighting moving member 221 in the front-back direction through the mounting portion 22211 movably connected to the first supplementary lighting moving member 221. The supplementary lighting adjusting plate 2222 is movably connected to a mounting portion 22211 along the fifth direction, that is, the vertical direction. That is, the supplementary lighting adjusting plate 2222 can reciprocate relative to the supplementary lighting adjusting rod 2221 in the vertical direction. The supplementary light 21 is connected to the supplementary lighting adjusting plate 2222. When the vertical position of the supplementary light 21 needs to be adjusted, the mounting part 22211 connected to the first supplementary light moving part 221 can be replaced to quickly achieve a large distance adjustment of the supplementary light 21 in the vertical direction, which can adapt to large differences in the thickness of the circuit board 90 or the height of the identification code. On this basis, fine-tuning can be performed by using the vertical movement of the supplementary light adjustment piece 2222 relative to the supplementary light adjustment rod 2221, which can accurately align with the plane where the identification code is located, ensuring that the light covers the target area at the optimal angle. This layered adjustment method takes into account both adjustment efficiency and accuracy. It can quickly respond to the needs of large positional changes, and can eliminate minor deviations through fine-tuning. It can effectively avoid problems such as excessively strong or weak illumination or reflection caused by improper distance. In conjunction with the front-to-back adjustment and angle adjustment of the supplementary light 21, it further improves the adaptability and stability of the supplementary lighting effect, providing a reliable guarantee for code scanning and recognition.

[0068] In one implementation, the mounting part 22211 can be a mounting hole 22211a opened on the supplementary light adjustment rod 2221, with multiple mounting holes 22211a arranged at intervals in the vertical direction. A third strip-shaped hole 2211 is opened on the first supplementary light moving member 221, extending in the front-back direction and penetrating both sides of the first supplementary light moving member 221 in the left-right direction. A fourth strip-shaped hole 22221 is opened on the supplementary light adjustment piece 2222, extending in the vertical direction and penetrating both sides of the supplementary light adjustment piece 2222 in the left-right direction. The supplementary light adjustment member 22 also includes a third fastener, which passes sequentially through the third strip-shaped hole 2211, the mounting hole 22211a, and the fourth strip-shaped hole 22221, and the third fastener can be slidably connected to both the third strip-shaped hole 2211 and the fourth strip-shaped hole 22221.

[0069] The third fastener includes a third screw and a third nut. The third screw passes through the third strip hole 2211, the mounting hole 22211a, and the fourth strip hole 22221. The third nut is threaded onto the third screw and, together with the nut of the third screw, clamps the first supplementary lighting moving part 221, the supplementary lighting adjusting rod 2221, and the supplementary lighting adjusting plate 2222. When a large distance adjustment of the position of the supplementary light 21 is required in the vertical direction, the mounting hole 22211a through which the third screw passes can be replaced, and the third screw can be inserted into a mounting hole 22211a that is closer to the correct position. Then, the third nut is loosened. The third fastener can drive the supplementary lighting adjusting rod 2221 and the supplementary light 21 to move smoothly in the front and back direction along the third strip hole 2211. At the same time, it can drive the supplementary lighting adjusting plate 2222 and the supplementary light 21 to complete precise fine-tuning in the vertical direction along the fourth strip hole 22221, so as to meet the supplementary lighting requirements of the identification code on different circuit boards 90 in the front and back, and vertical and horizontal positions. Once the position is determined, tightening the third nut will secure the supplementary light 21 to its current position through the locking force of the fastener, effectively preventing displacement caused by equipment vibration. This structure not only retains the versatility of initial mounting positions provided by the multiple mounting holes 22211a, adapting to complex spatial layouts, but also achieves stepless adjustment in the front-back and up-down directions through the cooperation of the strip holes and fasteners. It can accurately align the markings in areas such as component gaps and edge corners, optimizing the angle and range of light illumination and reducing problems such as glare or insufficient lighting. After being adjusted in conjunction with the barcode scanner 11, it can further improve the adaptability to different specifications of markings, ensure the stability and efficiency of barcode scanning and recognition, and enhance the practicality of the equipment in automated production.

[0070] Of course, the supplementary light adjustment rod 2221 may have a third strip hole 2211, the supplementary light adjustment plate 2222 may have a fourth strip hole 22221, and the first supplementary light moving part 221 may have a mounting hole 22211a. Alternatively, the first supplementary light moving part 221 may have a third strip hole 2211, the supplementary light adjustment rod 2221 may have a fourth strip hole 22221, and the supplementary light adjustment plate 2222 may have a mounting hole 22211a. There are no restrictions here.

[0071] As an alternative implementation, the third fastener can also be a third adjusting screw and a fourth adjusting screw. The third adjusting screw can be rotatably connected to the first supplementary lighting moving part 221 and threadedly connected to the supplementary lighting adjusting rod 2221. The fourth adjusting screw can be rotatably connected to the supplementary lighting adjusting rod 2221 and threadedly connected to the supplementary lighting adjusting plate 2222. By turning the third adjusting screw, the supplementary lighting adjusting rod 2221 and the supplementary light 21 can be smoothly adjusted in the front-back direction using threaded transmission. Turning the fourth adjusting screw can precisely adjust the supplementary lighting plate 2222 and the supplementary light 21 in the up-down direction. The two together can accurately adapt to the supplementary lighting needs of different circuit boards 90 with different front-back and up-down positions of the marking codes. At the same time, the threaded connection has a self-locking characteristic, and the current position can be kept stable without additional locking operation after adjustment, effectively preventing position displacement caused by equipment vibration. Of course, the third adjusting screw can also be rotatably connected to the supplementary light adjusting rod 2221 and threadedly connected to the supplementary light adjusting rod 2221, and the fourth adjusting screw can also be rotatably connected to the supplementary light adjusting plate 2222 and threadedly connected to the supplementary light adjusting rod 2221. There are no restrictions here.

[0072] Please see Figure 2 It is understood that the fill light 21 is rotatably connected to the fill light adjustment component 22. Thus, the fill light 21 can have its angle adjusted via the fill light adjustment component 22. In this embodiment, the fill light 21 is rotatably connected to the fill light adjustment plate 2222.

[0073] Optionally, the supplementary light adjustment plate 2222 has a rotating hole 22222 and an arc-shaped hole 22223. The arc-shaped hole 22223 extends circumferentially along the rotating hole 22222. Taking a barcode as an example, the length direction of the barcode can be left-right, and the supplementary light 21 is also a strip extending in the left-right direction. The supplementary light 21 includes a lamp housing 211 and a light source 212 connected to the lamp housing 211. The lamp housing 211 has an end plate 2111 at each end in the left-right direction. The end plate 2111 includes a rotating part and a sliding part connected together. The rotating part is rotatably connected to the rotating hole 22222, and the rotation axis extends in the left-right direction. The sliding part is slidably connected to the arc-shaped hole 22223. When it is necessary to adjust the angle of the supplementary light 21, the supplementary light 21 can be rotated by driving the sliding part to move along the arc-shaped hole 22223. The supplementary light adjustment plate 2222 forms a rotation fulcrum with the rotating part of the end plate 2111 of the supplementary light lamp 21 through the rotating hole 22222. With the sliding part sliding along the arc-shaped hole 22223, the supplementary light lamp 21 can achieve stable angle adjustment around the left and right axis, accurately adapting to the different requirements of the barcode for the light incident angle. The limiting design at both ends of the arc-shaped hole 22223 can prevent the supplementary light lamp 21 from rotating excessively beyond the effective supplementary light range, while taking into account the rotation flexibility and angle controllability, ensuring that the bar light source 212 can illuminate the barcode at the optimal angle, reducing reflection or uneven brightness problems, and improving the scanning clarity.

[0074] As an alternative implementation, the fill light adjustment plate 2222 may only have a rotating hole 22222, and the end plate 2111 of the fill light 21 can be rotatably connected to this rotating hole 22222. In this way, angle adjustment is achieved through the rotatable connection between the end plate 2111 of the fill light 21 and the rotating hole 22222, simplifying the structural design and significantly reducing the size of the fill light adjustment plate 2222. This compact layout effectively reduces the space occupied around the circuit board 90, making it particularly suitable for scenarios with dense components and narrow gaps, avoiding interference with other components, and improving the adaptability of the device in complex spatial environments while ensuring the angle adjustment function of the fill light 21.

[0075] As an alternative implementation, the supplementary light adjustment plate 2222 may only have an arc-shaped hole 22223. The end plate 2111 on the supplementary light lamp 21 can be slidably connected to the arc-shaped hole 22223. In this way, the supplementary light lamp 21 can rotate by sliding along the arc-shaped hole 22223. The full-range constraint of the sliding part by the arc-shaped hole 22223 enhances the connection stability between the supplementary light lamp 21 and the adjustment plate, reducing shaking or offset during rotation. This design does not require a separate rotation fulcrum; angle adjustment can be achieved by relying on the guiding effect of the arc-shaped hole 22223. The structure is simple and has a stronger load-bearing capacity. It can maintain the angle stability of the supplementary light lamp 21 under operating conditions such as equipment vibration, ensuring the consistency of light illumination effect and improving the reliability of the scanning process.

[0076] The supplementary light 21 has a rotation range of 60°-120° to meet the needs of a wide range of illumination adjustments.

[0077] Please see Figure 2 It is understandable that two supplementary lights 21 are provided, arranged at intervals along the fourth direction, i.e., at intervals along the front-to-back direction. A clearance space is formed between the two supplementary lights 21. The barcode scanner 11 scans upwards, and the clearance space is opposite to the barcode scanner 11 in the vertical direction, ensuring that the barcode scanner 11 can smoothly scan the identification code on the circuit board 90 through this space, avoiding obstruction of the scanning path by the supplementary lights 21. Simultaneously, the dual supplementary lights 21 significantly increase the illumination range, effectively covering areas where the identification code position may shift due to processing errors, ensuring that the identification code is always within the effective illumination range, reducing scanning failures caused by insufficient or missed illumination in certain areas. This layout balances comprehensive supplementary lighting with unobstructed scanning paths, and enhances the tolerance to production errors through dual-light collaboration, further ensuring the stability and efficiency of barcode recognition, and enhancing the applicability of the equipment in mass production scenarios.

[0078] In use, the two supplementary lights 21 can be directed towards the designated area of ​​the circuit board 90 from different directions. That is, the supplementary light 21 located on the front side can shine backward and upward, and the supplementary light 21 located on the rear side can shine forward and upward, so as to compensate for the blind spots of illumination near the identification code, effectively eliminate the shadows formed by the components near the identification code, and ensure that the code details are clearly distinguishable.

[0079] exist Figure 2 In the illustrated embodiment, two supplementary lighting adjustment components 22 may be provided, with each supplementary light lamp 21 having two end plates 2111 rotatably connected to a supplementary lighting adjustment plate 2222 in a supplementary lighting adjustment component 22. This ensures that both ends of each supplementary light lamp 21 are supported. This double-end support structure significantly improves the stability of the supplementary light lamp 21 during angle adjustment and operation, effectively avoiding the swaying or offset that may occur with single-end support, ensuring that the strip supplementary light lamp 21 always accurately illuminates the barcode area at a preset angle. Simultaneously, stable support guarantees the long-term reliable operation of the supplementary light lamp 21, reducing fluctuations in the supplementary lighting effect caused by structural loosening. Combined with the layout of the dual supplementary light lamps 21, this further enhances the adaptability to complex working conditions, ensures the continuous stability of barcode scanning and recognition, and improves the durability and reliability of the equipment in mass production.

[0080] It is understood that the barcode scanning device 100 also includes a mounting base, and both the barcode scanning mechanism 10 and the supplementary lighting mechanism 20 are movably connected to the mounting base, so that the barcode scanning mechanism 10 and the supplementary lighting mechanism 20 form an integral structure. Specifically, the first barcode scanning moving part 121 is movably connected to the mounting base in the left-right direction, and the first supplementary lighting moving part 221 is movably connected to the mounting base in the left-right direction. In this way, the assembly process of the equipment is simplified, and the two parts can be pre-installed and debugged on the mounting base before being integrated into the production line, which greatly shortens the on-site installation time. At the same time, the relative positional accuracy of the barcode scanning mechanism 10 and the supplementary lighting mechanism 20 is ensured by a unified installation benchmark, reducing the positioning deviation caused by scattered installation. At the same time, the movable connection of the two parts to the mounting base in the same direction (left-right direction) facilitates the synchronous adjustment of the lateral position of the barcode scanner 11 and the supplementary lighting lamp 21, so that the two parts respond more consistently when coordinating to adapt to different circuit board widths 90 or the lateral distribution of the identification codes, avoiding the influence of relative positional misalignment on the supplementary lighting and barcode scanning effect. This integrated design not only improves the compactness and positional stability of the equipment structure, but also facilitates later maintenance, further enhancing the practicality and reliability of the equipment in automated production.

[0081] Optionally, the first scanning moving part 121 has a fifth strip hole 1213 extending in the left-right direction, and the first supplementary lighting moving part 221 has a sixth strip hole 2212 extending in the left-right direction. The first scanning moving part 121 can be slidably connected to the mounting base in the left-right direction by a fifth fastener passing through the fifth strip hole 1213, and the first supplementary lighting moving part 221 can be slidably connected to the mounting base in the left-right direction by a sixth fastener passing through the sixth strip hole 2212.

[0082] exist Figure 2 In the illustrated embodiment, the first supplementary lighting moving member 221 includes a first plate portion 221a and a second plate portion 221b. Both the first plate portion 221a and the second plate portion 221b are flat and are vertically connected to form an L-shaped structure. The first plate portion 221a extends in the left-right direction and has a plurality of fifth strip holes 1213. The plurality of fifth strip holes 1213 are arranged at intervals in the up-down direction. The second plate portion 221b extends in the front-back direction and has two sets of third strip holes 2211. The two sets of third strip holes 2211 are arranged at intervals in the front-back direction. Each set of third strip holes 2211 includes a plurality of third strip holes 2211 arranged in the up-down direction. The two second supplementary lighting moving members 222 can be connected to a set of third strip holes 2211 respectively.

These descriptions are only for explaining the principles of this application and should not be construed as limiting the scope of protection of this application in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application, as well as other specific embodiments of this application that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of this application.
