Description

Technical Field

[0001] This invention relates to the field of barcode reader protection technology, specifically to an industrial barcode reader housing with a modular dustproof and waterproof structure. Background Technology

[0002] In industrial scenarios such as intelligent manufacturing, logistics sorting, automobile manufacturing, and food packaging, industrial barcode readers, as core data acquisition devices, need to operate continuously in complex and harsh environments such as dust, humidity, oil, and high-frequency collisions. The protective performance, heat dissipation effect, installation adaptability, and maintenance convenience of their shells directly determine the working stability, recognition accuracy, and service life of the barcode readers, which are the key foundation for ensuring smooth industrial production processes and accurate data acquisition.

[0003] Currently, most industrial barcode reader housings on the market employ a single sealed structure design, offering limited protection and failing to meet the demands of harsh industrial environments. Most housings achieve dust and water resistance solely through simple sealant or a single-layer shell, which not only fails to effectively prevent the intrusion of industrial dust, liquid water, and oil, but also allows dust and moisture to enter the housing due to aging of the sealing structure and leakage from gaps. This can cause moisture-induced short circuits and dust accumulation malfunctions in the reader's internal optical lenses, CMOS components, and circuit boards, leading to decreased reading accuracy, equipment downtime, and significantly increasing equipment maintenance costs and the risk of production interruptions.

[0004] In terms of heat dissipation design, existing industrial barcode reader housings generally suffer from the dilemma of balancing heat dissipation and protection: if ventilation holes are added to improve heat dissipation efficiency, the integrity of the housing's seal will be compromised, leading to a significant decrease in dust and water resistance; if a fully sealed structure is adopted to pursue protection, the heat generated by the barcode reader cannot be dissipated in time, and long-term accumulation will cause equipment performance degradation, accelerated aging of internal components, and even overheating and shutdown, especially in high-temperature industrial environments. In addition, the clamping and mounting structures of existing housings are mostly designed with fixed specifications, which cannot flexibly adjust the clamping size and can only be adapted to specific barcode reader models, resulting in poor versatility. When enterprises change to different specifications of barcode readers, they must also change the corresponding housing, increasing equipment adaptation costs. Summary of the Invention

A clamping and mounting assembly for fixing the industrial barcode reader is installed inside the protective shell 1. A flow guide cavity 27 is formed inside the protective shell 1. A second heat dissipation groove 14 is formed on the side of the flow guide cavity 27 near the inner cavity of the protective shell 1, and a first heat dissipation groove 8 is formed on the side of the flow guide cavity 27 near the outer side of the protective shell 1.

A connecting frame 2 is fixedly installed on one side of the protective shell 1, and a shielding cloth 3 is fixedly installed on the side of the connecting frame 2 away from the protective shell 1. A rubber ring 4 is fixedly installed inside the shielding cloth 3. The clamping and mounting assembly... The assembly includes an assembly component and a clamping component. The assembly component includes an assembly column 21 and an assembly ring 25. The outer dimensions of the assembly column 21 match the inner dimensions of the assembly ring 25. A magnet 22 is fixedly installed inside the assembly column 21, and a magnet 26 is fixedly installed inside the assembly ring 25. The magnetic poles of the magnets 22 and 26 are opposite. The clamping component includes an end plate 24. The assembly column 21 is fixedly installed on one side of the end plate 24. A sliding groove 19 is provided on one side of the end plate 24. Two threaded hole blocks are slidably installed inside the sliding groove 19, and a clamping plate 18 is fixedly installed on one side of the two threaded hole blocks. A threaded rod 20 is rotatably installed inside the sliding groove 19, and the threaded rod 20 is threadedly connected. Inside the two threaded blocks, the threads at both ends of the threaded rod 20 are in opposite directions, and the threads inside the two threaded blocks are also in opposite directions. A hand-operated handle 23 is fixedly installed at one end of the threaded rod 20. Rubber pads 17 are fixedly installed on opposite sides of the clamping plate 18. A insertion groove 9 is provided on the side of the guide cavity 27 near the outer side of the protective shell 1, and a snap-fit ​​groove 10 is provided on the side of the guide cavity 27 near the inner side of the protective shell 1. An installation frame 28 is snap-fitted inside the insertion groove 9. A dustproof, waterproof, and breathable membrane 29 is fixedly installed inside the installation frame 28. The threaded rod 20 is fixedly installed on one side of the installation frame 28, and the snap-fit ​​strip 30 is snap-fitted inside the snap-fit ​​groove 10. A sealing plate 5 is fixedly installed on one side of the installation frame 28. A handle 6 is fixedly installed on the side of the blocking plate 5 away from the mounting frame 28. An outer tube 31 is fixedly installed inside the heat dissipation slot 8. A guide plate 35 and a guide plate 37 are fixedly installed on the outside of the outer tube 31. The sides of the guide plate 35 and the guide plate 37 near the inner wall of the heat dissipation slot 8 are wavy. A desiccant bag 38 is inserted into the inside of the outer tube 31. A rectangular groove 36 is opened on the outside of the outer tube 31. An insertion hole 39 is opened inside the protective shell 1. A connecting post 34 is slidably installed inside the insertion hole 39. One end of the connecting post 34 is fixedly connected to the desiccant bag 38. An anti-blocking plate 13 is fixedly installed on the other end of the connecting post 34. A push plate 7 is fixedly installed on one side of the anti-blocking plate 13.

[0029] The working principle of the above technical solution is as follows: First, the industrial barcode reader is precisely fixed by the clamping and mounting components. During operation, the handwheel 23 is turned, which drives the threaded rod 20 fixedly connected to it to rotate synchronously. Since the thread directions at both ends of the threaded rod 20 are opposite, and the thread directions inside the two threaded hole blocks are adapted to the threads of the corresponding end threaded rod, the two threaded hole blocks will move closer to each other along the sliding groove 19 on one side of the end plate 24 during rotation, thereby driving the clamping plate 18 fixed on one side of the threaded hole block to move synchronously. Rubber pads 17 are fixed on opposite sides of the clamping plate 18, which can play a buffering and protective role when clamping the barcode reader to avoid damaging the equipment shell, while increasing the clamping friction and preventing displacement of the barcode reader during operation. In addition, the assembly column 21 and the assembly ring 2 5. The splicing is achieved through the precise fit between its outer and inner contours. Furthermore, the magnet 22 inside the assembly column 21 and the magnet 26 inside the assembly ring 25 have opposite magnetic poles, further reinforcing the assembly structure and improving the overall stability of the clamping and mounting components. This ensures the barcode reader remains fixed in complex industrial environments. To ensure the barcode reader can clearly identify external barcodes, an inner transparent glass 16 is fixedly installed in the circular groove 15 at the bottom of the protective shell 1 to isolate the barcode reader inside the shell from the external environment while ensuring normal light transmission. The shell adopts a multi-modal sealing structure to achieve all-round dust and water protection. A connecting frame 2 is fixed on one side of the protective shell 1, and a shielding cloth 3 is installed on the side away from the protective shell 1. The shielding cloth 3 has a fixed internal structure... The rubber ring 4 can tightly fit the connection parts of the equipment, sealing the gaps on the side of the protective shell 1 and preventing external dust and water droplets from entering the shell. The installation frame 28 is snapped into the insertion groove 9 near the outer side of the protective shell 1 in the flow guide cavity 27. The dustproof, waterproof and breathable membrane 29 fixed inside the installation frame 28 completely covers the flow guide cavity 27, which can effectively prevent dust and liquid water from entering the flow guide cavity 27, while allowing normal air circulation to provide conditions for subsequent heat dissipation. The snap-fit ​​strip 30 on one side of the installation frame 28 snaps into the snap-fit ​​groove 10 on the inner side of the flow guide cavity 27 to achieve precise positioning and fixation of the installation frame 28. The sealing plate 5 on the other side of the installation frame 28 can further seal the insertion groove 9 to enhance the sealing effect, while the handle 6 allows the operator to quickly disassemble the installation frame 28. The dustproof, waterproof, and breathable membrane 29 is replaced and maintained to ensure long-term stable protective performance. During long-term operation, the barcode reader generates a large amount of heat. If this heat cannot be dissipated in time, it will affect the device's performance and even damage internal components. Therefore, the housing is designed with a highly efficient heat dissipation structure. The heat generated by the barcode reader is first conducted to the airflow guiding cavity 27 through the heat dissipation groove 14 on one side of the inner cavity of the protective housing 1. Simultaneously, cold air from the outside enters the airflow guiding cavity 27 through the heat dissipation groove 8 on the outer side of the protective housing 1, forming a convection of hot and cold air. The outer sleeve 31 fixed inside the heat dissipation groove 8 is equipped with a first airflow guide plate 35 and a second airflow guide plate 37, respectively. Both are designed with a wavy shape on the side closest to the inner wall of the heat dissipation groove 8. This structure can significantly increase the contact area between hot and cold air, accelerating heat exchange.To improve heat dissipation efficiency, the desiccant bag 38 inserted inside the outer tube 31 effectively absorbs moisture from the air in the airflow cavity 27, preventing moisture from entering the inner cavity of the protective shell 1 and contacting the barcode reader, thus preventing internal components from short-circuiting due to moisture. This provides dual protection against heat dissipation and moisture. As the usage time increases, the desiccant bag 38 inside the outer tube 31 will gradually lose its moisture absorption capacity and needs to be replaced regularly to ensure the moisture-proof effect. When replacing it, the operator only needs to push the push plate 7, which will move the anti-blocking plate 13 and the connecting post 34 fixedly connected to it along the insertion hole 3 inside the protective shell 1. 9. Sliding: The other end of the connecting post 34 is fixedly connected to the desiccant bag 38. Therefore, during the sliding process, the desiccant bag 38 can be pulled out from the outer sleeve 31 to complete the removal of the old desiccant bag. After replacing the new desiccant bag, push the push plate 7 in the opposite direction to reset the connecting post 34 and the desiccant bag 38, allowing the desiccant bag 38 to be reinserted into the outer sleeve 31. At the same time, the anti-blocking plate 13 tightly adheres to the surface of the protective shell 1, sealing the insertion hole 39 to prevent external dust and water droplets from entering the shell through the insertion hole 39, ensuring that the replacement process does not affect the overall dustproof and waterproof performance of the shell.

[0030] In another implementation scheme, such as Figures 1-9 As shown, a protective cover 12 is detachably installed on the bottom of the protective shell 1. An outer transparent glass 11 is fixedly installed inside the protective cover 12, and the outer transparent glass 11 is located directly below the inner transparent glass 16. An inner threaded groove 32 is opened at the bottom of the protective shell 1, and an outer threaded ring 33 is fixedly installed on the top of the protective cover 12. The outer threaded ring 33 is threadedly connected to the inner side of the inner threaded groove 32.

[0031] Inside the detachable protective cover 12 at the bottom of the protective shell 1, an outer transparent glass 11 is fixed directly below the inner transparent glass 16, forming a double-layer light-transmitting protective structure. This not only improves the light transmission effect but also effectively blocks external dust and water droplets from directly contacting the inner transparent glass 16, reducing the risk of glass stains and scratches. The protective cover 12 is threadedly connected to the inner threaded groove 32 at the bottom of the protective shell 1 via the external threaded ring 33 at the top. This detachable design allows staff to regularly remove the protective cover 12 to clean the inner and outer transparent glass layers, preventing stains and dust on the glass surface from affecting the reader's recognition accuracy and ensuring stable and smooth code reading operation. Working principle: First, the industrial barcode reader is precisely fixed by the clamping and mounting components. During operation, turning the handwheel 23 causes the threaded rod 20, which is fixedly connected to it, to rotate synchronously. Since the thread directions at both ends of the threaded rod 20 are opposite, and the thread directions inside the two threaded holes are matched with the threads of the corresponding ends of the threaded rod, the two threaded holes will move closer to each other along the sliding groove 19 on one side of the end plate 24 during rotation. This, in turn, causes the clamping plate 18 fixed on one side of the threaded holes to move synchronously. Rubber pads 17 are fixed on opposite sides of the clamping plate 18, which can provide cushioning when clamping the barcode reader. The protective structure prevents damage to the equipment casing and enhances clamping friction to prevent displacement of the barcode reader during operation. Furthermore, the assembly column 21 and assembly ring 25 are precisely joined through the matching of their outer and inner contours. The magnet 22 inside the assembly column 21 and the magnet 26 inside the assembly ring 25 have opposite magnetic poles on their opposing faces, further reinforcing the assembly structure and improving the overall stability of the clamping and mounting components. This ensures the barcode reader remains fixed in complex industrial environments. To ensure the barcode reader can clearly identify external barcodes, a fixed mounting device is installed in the circular groove 15 at the bottom of the protective casing 1. An inner transparent glass 16 is installed to isolate the internal barcode reader from the external environment while ensuring normal light transmission. Inside the removable protective cover 12 at the bottom of the protective shell 1, an outer transparent glass 11 is fixed directly below the inner transparent glass 16, forming a double-layer light-transmitting protective structure. This not only improves light transmission but also effectively blocks external dust and water droplets from directly contacting the inner transparent glass 16, reducing the risk of glass stains and scratches. The protective cover 12 is threadedly connected to the inner threaded groove 32 at the bottom of the protective shell 1 via an external threaded ring 33 at the top. This detachable design facilitates the periodic removal of the protective cover 12 by personnel. The inner and outer transparent glass layers are cleaned to prevent stains and dust on the glass surface from affecting the reader's recognition accuracy and to ensure stable and smooth reading operation. The outer shell adopts a multi-modal sealing structure to achieve all-round dust and water protection. The connecting frame 2 is fixed on one side of the protective shell 1, and a shielding cloth 3 is installed on the side away from the protective shell 1. The rubber ring 4 fixed inside the shielding cloth 3 can tightly fit the equipment connection parts to seal the gaps on the side of the protective shell 1, preventing external dust and water droplets from entering the shell from the gaps. The mounting frame 28 is snapped into the insertion slot 9 near the outer side of the protective shell 1 in the guide cavity 27.The dustproof, waterproof, and breathable membrane 29, fixed inside the mounting frame 28, completely covers the flow channel 27, effectively preventing dust and liquid water from entering while allowing normal airflow for subsequent heat dissipation. A snap-fit ​​strip 30 on one side of the mounting frame 28 engages with a snap-fit ​​groove 10 inside the flow channel 27, ensuring precise positioning and fixation of the mounting frame 28. A sealing plate 5 on the other side of the mounting frame 28 further seals the insertion groove 9, enhancing the sealing effect. A pull handle 6 allows workers to quickly disassemble the mounting frame 28 to replace and maintain the dustproof, waterproof, and breathable membrane 29, ensuring long-term stable protective performance. As the barcode reader generates a significant amount of heat during prolonged operation, failure to dissipate this heat can negatively impact performance and even damage internal components. Therefore, the casing is designed with an efficient heat dissipation structure. The heat generated by the reader is first conducted to the airflow cavity 27 via a heat dissipation groove 14 on one side of the inner cavity of the protective casing 1. Simultaneously, cool air from the outside enters the airflow cavity 27 through a heat dissipation groove 8 on the outer side of the protective casing 1, creating a convection flow between hot and cold air. A first airflow plate 35 and a second airflow plate 37 are installed on the outer side of the fixed outer sleeve 31 inside the heat dissipation groove 8. Both of these plates have a wavy design on the side closest to the inner wall of the heat dissipation groove 8. This structure significantly increases the contact area between hot and cold air, accelerating heat exchange and improving heat dissipation efficiency. Furthermore, the desiccant bag 38 inserted inside the outer tube 31 effectively absorbs moisture from the air in the guide cavity 27, preventing moisture from entering the inner cavity of the protective shell 1 and contacting the code reader, thus preventing internal components from short-circuiting due to moisture. This provides dual protection against heat dissipation and moisture. As usage time increases, the desiccant bag 38 inside the outer tube 31 will gradually lose its moisture-absorbing capacity and needs to be replaced periodically to maintain its moisture-proof effect. During replacement, the operator only needs to push the push plate 7, which will move the anti-blocking plate 13 and connecting column fixedly connected to it. The connecting post 34 slides along the insertion hole 39 inside the protective shell 1. The other end of the connecting post 34 is fixedly connected to the desiccant bag 38. Therefore, during the sliding process, the desiccant bag 38 can be pulled out from the outer sleeve 31, completing the removal of the old desiccant bag. After replacing the new desiccant bag, push the push plate 7 in the opposite direction to reset the connecting post 34 and the desiccant bag 38, allowing the desiccant bag 38 to be re-inserted into the outer sleeve 31. At the same time, the anti-blocking plate 13 tightly adheres to the surface of the protective shell 1, sealing the insertion hole 39 to prevent external dust and water droplets from entering the shell through the insertion hole 39, ensuring that the replacement process does not affect the overall dustproof and waterproof performance of the shell.
