Description

Technical Field

[0001] This utility model relates to the field of telescopic barcode scanner technology, and in particular to a telescopic barcode scanner for inventory counting on high-level shelves. Background Technology

[0002] As the warehousing and logistics industry develops towards large-scale and intensive operations, high-bay racking has become the mainstream choice for storing goods in e-commerce, manufacturing and other fields because it can maximize the use of vertical space (usually 8 to 15 meters in height). While some existing adjustable-length barcode scanners can be lengthened through sleeve assembly, the sleeve assembly is mostly a segmented fixed structure. Adjustments require disassembling and reassembling the sleeves, making it impossible to achieve fine length adjustments during scanning. If there are slight deviations in the position of goods on the shelf, it is difficult to quickly adapt, leading to a significant decrease in scanning efficiency. Furthermore, the sleeve joints lack a tight locking and cushioning structure, relying solely on simple pins or bolts for fixation. This results in insufficient overall rigidity, making them prone to wobbling under slight external forces (such as minor collisions or uneven hand pressure) during scanning. This not only affects scanning clarity but may also cause the scanning position to shift, requiring repeated adjustments for successful recognition, further increasing the tediousness of the operation. Additionally, these devices rely on simple fixing methods, often using temporary binding or manual hand-holding, which cannot be securely fixed to the shelf, further amplifying the wobbling problem. Therefore, improvements are needed to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a retractable barcode scanner for inventory management on high-bay shelves.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a retractable barcode scanner for inventory management on high-level shelves, comprising a shelf, a central connecting cylinder movably disposed on one side of the shelf, an upper sleeve and a lower sleeve respectively slidingly sleeved at both ends of the upper end of the central connecting cylinder, the central connecting cylinder, the upper sleeve and the lower sleeve being rectangular in plan view, a triangular support frame being bolted to three sides of the lower sleeve, a movable sleeve being bolted to one end of the triangular support frame, a hollow cylinder being sleeved inside the movable sleeve, a caster wheel being installed at one end of the bottom surface of the hollow cylinder, and the movable sleeve being equidistant from the top surface of the hollow cylinder. The upper sleeve has multiple first bolt holes of the same diameter for inserting bolts. A fixed frame is provided at the lower end of one side of the upper sleeve. A lifting rod is movably raised and lowered inside the upper sleeve. A rotary motor is fixed to the top of the lifting rod. A swing rod is fixed to the outer wall of the output shaft of the rotary motor. A sliding sleeve is sleeved on the swing rod. A lead screw box is fixed to the lower end of one side of the sliding sleeve. A lead screw groove is opened on the top surface of the lead screw box. A lead screw is rotatably installed in the lead screw groove. A first motor installed in the lead screw box is coaxially fixed to one end of the lead screw. A sliding block that slides along the lead screw groove is sleeved on the lead screw. A scanning camera is fixed to one end of the sliding block.

[0005] Preferably, the fixing frame has a C-shaped cross-section, and the outer walls on both sides of its opening are screwed together with clamping bolts, the bolts of which penetrate the inner wall of the fixing frame.

[0006] Preferably, the middle connecting cylinder, the upper sleeve, and the lower sleeve are provided with multiple pin holes of the same diameter at equal intervals on three circumferential sides. The middle connecting cylinder is fixedly connected to the upper sleeve and the lower sleeve by locking pins passing through the pin holes.

[0007] Preferably, a screw is rotatably provided inside the upper sleeve, and a driven bevel gear is coaxially fixed to the bottom end of the screw. A driving bevel gear meshes with one side of the driven bevel gear, and a second motor installed on the outer wall of one side of the upper sleeve is coaxially fixed to one end of the driving bevel gear. A threaded lifting hole is provided at the bottom end of the lifting rod, which is screwed to the screw.

[0008] Preferably, the lower sleeve has a plurality of hinge seats that are equidistantly provided on the circumference of the bottom end, which are hinged to one end of the hollow cylinder, and a fixing bolt is provided between the hollow cylinder and the movable sleeve through the first bolt hole.

[0009] Preferably, the opening of the fixing frame extends into one side of the support platform corresponding to the shelf, and the screws of the two clamping bolts abut against the top and bottom surfaces of the support platform of the shelf, respectively.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the screw connection between the screw inside the upper sleeve and the lifting rod, facilitates the precise lifting and lowering of the scanning camera by driving the lifting rod, improving the convenience of length fine-tuning. This allows for rapid adaptation to minor positional deviations of goods on the shelf during the scanning process. Furthermore, the meshing of the second motor with the driving and driven bevel gears provides stable power for the screw rotation, improving the automation of lifting and adjusting. This enables length fine-tuning without disassembly, ultimately solving the problem of existing devices requiring disassembly and adjustment during sleeve assembly, which limits fine-tuning capabilities. The problem of low scanning efficiency caused by adjustment has been addressed by improving scanning efficiency and ease of fine-tuning. The sliding cooperation between the middle connecting cylinder and the upper and lower sleeves facilitates adjustment of the overall length of the rod, followed by a tight lock achieved through the engagement of the locking pin and pin hole, increasing the rigidity of the rod joints and reducing shaking during scanning. Furthermore, the cooperation between the triangular support frame, movable sleeve, and hollow cylinder allows for extending the support distance and bolt fixation, improving the overall support stability of the device and enhancing its resistance to external interference. Ultimately, this solves the problems of loose sleeve splicing and locking, insufficient overall rigidity, and susceptibility to damage in existing devices. The device addresses the swaying issue by improving barcode scanning clarity and positional stability. The opposing screw connections between the mounting bracket and the clamping bolts facilitate secure clamping of the device onto the shelf's support platform, enhancing stability and replacing temporary binding or manual handling. Furthermore, the hinged connection between the lower sleeve's bottom and the hollow cylinder allows for easy adjustment of the hollow cylinder's support angle, complemented by casters, improving the device's contact stability with the ground and further suppressing swaying. Ultimately, this solves the problem of existing devices having a single, ineffective fixation method that amplifies swaying when firmly secured to shelves. This design improves the overall stability of the device. The cooperation between the sliding sleeve on the swing arm and the lead screw and sliding block in the lead screw box facilitates the lateral movement of the scanning camera along the swing arm, increasing the flexibility of scanning position adjustment and enabling precise scanning of goods at different positions on the same height level. Furthermore, the cooperation between the rotating motor and the swing arm facilitates horizontal rotation and angle adjustment, increasing the scanning coverage area and reducing repeated adjustments due to positional deviations. Ultimately, this solves the problems of inflexible adjustment and repeated adjustments due to positional shifts in existing devices, improving scanning accuracy and ease of operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 4This utility model discloses a retractable barcode scanner for inventory management on high-level shelves, comprising a shelf 1. A central connecting cylinder is movably mounted on one side of the shelf 1. An upper sleeve 2 and a lower sleeve 8 are slidably fitted onto the upper ends of the central connecting cylinder. The central connecting cylinder, the upper sleeve 2, and the lower sleeve 8 are rectangular in plan view. Triangular support frames 5 are bolted to three sides of the lower sleeve 8. A movable sleeve is bolted to one end of the triangular support frame 5. A hollow cylinder is fitted inside the movable sleeve. A caster wheel 3 is installed at one end of the bottom surface of the hollow cylinder. Multiple first bolt holes of the same diameter for bolts are equidistantly opened on the top surface of the movable sleeve and the hollow cylinder. A fixed frame 7 is provided at the lower end of one side of the upper sleeve 2. A lifting rod is movably raised and lowered inside the upper sleeve 2. A rotary motor 6 is fixed to the top of the lifting rod. The output of the rotary motor 6... A swing rod is fixed to the outer wall of the shaft, and a sliding sleeve is sleeved on the swing rod. A lead screw box is fixed to the lower end of one side of the sliding sleeve. A lead screw groove is opened on the top surface of the lead screw box, and a lead screw is rotatably installed in the lead screw groove. A first motor installed in the lead screw box is coaxially fixed to one end of the lead screw. A sliding block that slides along the lead screw groove is sleeved on the lead screw, and a scanning camera 4 is fixed to one end of the sliding block. The shelving unit 1, the middle connecting cylinder, the upper sleeve 2, the lower sleeve 8, the lifting rod, the swing rod, the lead screw box, the triangular support frame 5, the hollow cylinder, the fixing frame 7, and the sliding block are all made of stainless steel, which is high in strength and corrosion-resistant, and suitable for humid and dusty storage environments. The lead screw is made of 45 steel, which is stable and wear-resistant. The first motor is a three-phase asynchronous motor of model Y2-63M1-2, which is small in size, has controllable speed, and can drive precisely. The lead screw adjusts the lateral position of the scanning camera 4; the rotary motor 6 uses a 42BYGH4818 stepper motor with high positioning accuracy, which can precisely control the horizontal rotation of the swing arm; the universal wheels 3 use DS21 series silent universal wheels, which are wear-resistant and quiet, facilitating device movement; the sliding cooperation between the middle connecting cylinder and the upper sleeve 2 and lower sleeve 8 can adjust the overall length of the rod to adapt to different height shelves; the triangular support frame 5, the movable sleeve, and the hollow cylinder can extend the support distance; the lifting rod drives the scanning camera 4 to rise and fall, and the rotary motor 6 cooperates with the swing arm and lead screw box to adjust the scanning position; the above structural cooperation constitutes the basic framework of the device, providing a retractable and adjustable barcode scanning structure support for high-level shelf inventory; the fixed frame 7 has a cross-section of... The device is C-shaped, with clamping bolts 11 screwed onto the outer walls on both sides of its opening. The bolts of the clamping bolts 11 penetrate the inner wall of the fixing frame 7. The fixing frame 7 is made of stainless steel, which is structurally stable and resistant to deformation. The clamping bolts 11 are made of No. 45 steel, which is high in strength and reliable in connection. The C-shaped section of the fixing frame 7 makes it easy to lock onto the support platform of the shelf 1. The clamping bolts 11 screwed onto each other can be tightened from both the top and bottom surfaces, ensuring that the device is firmly fixed on the shelf 1. This prevents the device from shaking during the inventory process and affecting the scanning accuracy, thus improving the overall stability of the device. The three sides of the middle connecting cylinder, the upper sleeve 2, and the lower sleeve 8 are all equally spaced with multiple pin holes of the same diameter. The middle connecting cylinder is fixedly connected to the upper sleeve 2 and the lower sleeve 8 by inserting locking pins 12 through the pin holes.The middle connecting sleeve, upper sleeve 2, and lower sleeve 8 are all made of stainless steel, which is wear-resistant and deformation-resistant; the locking pin 12 is made of No. 45 steel, which is high-strength and easy to insert and remove; multiple sets of pin holes of the same diameter provide multiple fixing options for the middle connecting sleeve and upper sleeve 2 and lower sleeve 8. After the locking pin 12 is inserted, it can quickly lock the adjusted rod length, preventing the sleeve from slipping during the inventory process and causing changes in the rod length, thus ensuring the stability of the scanning position.

[0015] In this utility model, a screw is rotatably mounted inside the upper sleeve 2. A driven bevel gear is coaxially fixed to the bottom end of the screw. A driving bevel gear meshes with one side of the driven bevel gear. A second motor 10 is coaxially fixed to one end of the driving bevel gear and mounted on the outer wall of one side of the upper sleeve 2. A threaded lifting hole for screwing the screw is opened at the bottom end of the lifting rod. The upper sleeve 2 and the lifting rod are made of stainless steel, with high structural strength. The screw, driving bevel gear, and driven bevel gear are made of 45# steel, with high transmission accuracy and strong wear resistance. The second motor 10 is a three-phase asynchronous motor of model Y2-71M1-2, with stable power and moderate torque. The second motor 10 drives the screw to rotate through the meshing transmission of the driving bevel gear and the driven bevel gear. The threaded engagement between the screw and the lifting rod converts the rotational motion into linear lifting motion, realizing precise height adjustment of the scanning camera 4, adapting to the inventory needs of different shelf layers, and improving the accuracy and automation of height adjustment. Multiple hinges corresponding to one end of the hollow cylinder are equidistantly arranged on the circumference of the bottom end of the lower sleeve 8. The hinge seat 9; the lower sleeve 8, hollow cylinder, and hinge seat 9 are all made of stainless steel, which has excellent corrosion resistance and structural strength, and can be used for long-term stable hinged connection; the hinge seat 9 realizes the hinged connection between the hollow cylinder and the lower sleeve 8, so that the hollow cylinder can rotate around the hinge seat 9, which is convenient for adjusting the support angle of the hollow cylinder to adapt to different ground environments or device placement needs. At the same time, it can reduce space occupation when folded and stored, and improve the flexibility of device use; the opening of the fixing frame 7 extends into one side of the support platform of the shelf 1, and the screws of the two clamping bolts 11 abut against the top and bottom surfaces of the support platform of the shelf 1 respectively; the fixing frame 7 is made of stainless steel, which has strong clamping stability; the clamping bolts 11 are made of No. 45 steel, which has high thread strength and is not easy to strip; after the opening of the fixing frame 7 extends into the support platform, the two clamping bolts 11 abut against the top and bottom surfaces from both sides, forming a stable clamping and fixing structure, preventing the device from shifting or shaking during the scanning process, further strengthening the connection stability between the device and the shelf 1, and ensuring the smooth operation of the scanning operation.

[0016] Working principle: When using this utility model, firstly, the fixing and movement of the device are accomplished with the help of the fixing frame 7, the triangular support frame 5, and the casters 3. The opening of the fixing frame 7 is inserted into the corresponding support platform of the shelf 1, and the clamping bolts 11 on both sides of the outer wall of the opening of the fixing frame 7 are tightened, so that the screws of the two clamping bolts 11 abut against the top and bottom surfaces of the support platform of the shelf 1, thereby firmly fixing the entire device on the shelf 1 and preventing the device from shaking during inventory. At the same time, the three sides of the lower sleeve 8 are fixed to the triangular support frame 5 by bolts, and one end of the triangular support frame 5 is fixed to the movable sleeve by bolts. The movable sleeve cooperates with the hollow cylinder inside to extend the length of the hollow cylinder. To adjust the extension length, the hollow cylinder is slid along the movable sleeve according to the stability requirements of the device. After adjustment, fixing bolts are inserted through the first bolt holes on the top surface of the hollow cylinder and the movable sleeve to fix the two, thereby fixing the extension length of the hollow cylinder. The universal wheel 3 at one end of the bottom surface of the hollow cylinder can assist the device in moving and adjusting its position, and together with the fixed hollow cylinder, further improve the overall stability of the device and adapt to different warehouse floor environments. Secondly, the extension and retraction adjustment of the device is achieved through the middle connecting cylinder, the upper sleeve 2, the lower sleeve 8 and the locking pin 12. The upper ends of the middle connecting cylinder slide and are respectively fitted with the upper sleeve 2 and the lower sleeve 8. According to the height requirements of the shelf, the upper sleeve 2 or the lower sleeve 8 is pulled. The lower sleeve 8 slides along the middle connecting sleeve to adjust the overall length of the rod. Once the length is adjusted to match the shelf height, locking pins 12 are inserted through the pin holes on the three sides of the middle connecting sleeve, upper sleeve 2, and lower sleeve 8 to securely connect them, ensuring the rod length remains stable during inventory checks and preventing scanning position shifts due to extension or retraction. Furthermore, the height adjustment of the scanning camera 4 is achieved through a lifting structure within the upper sleeve 2. The second motor 10, installed on one side of the outer wall of the upper sleeve 2, is activated. The output shaft of the second motor 10 drives the active bevel gear to rotate. The active bevel gear meshes with the driven bevel gear, causing the screw coaxially fixed to the driven bevel gear to rotate within the upper sleeve 2. Because... The bottom of the lifting rod has a threaded lifting hole that is screwed to the screw. When the screw rotates, it drives the lifting rod to move up and down along the upper sleeve 2, thereby driving the rotating motor 6, swing rod and scanning camera 4 at the top of the lifting rod to rise and fall synchronously, adapting to the inventory needs of different shelf heights. Finally, the horizontal angle and lateral position of the scanning camera 4 are adjusted by the rotating motor 6, swing rod and screw box. When the rotating motor 6 at the top of the lifting rod is started, the output shaft of the rotating motor 6 drives the swing rod fixed to the outer wall to rotate horizontally. Adjusting the horizontal angle of the swing rod changes the scanning angle of the scanning camera 4 in the horizontal direction, ensuring that it can be aligned with items at different horizontal positions on the same shelf height.Simultaneously, the sliding sleeve fitted on the swing rod can slide along the swing rod to initially adjust the lateral position of the scanning camera 4. For more precise adjustment, the first motor installed in the lead screw box is activated. The first motor drives the lead screw in the lead screw groove to rotate, causing the sliding block fitted on the lead screw to slide along the lead screw groove. The scanning camera 4, fixed to one end of the sliding block, moves accordingly, ultimately achieving precise scanning of items at different heights and horizontal positions on the shelf. When not in use, the triangular support frame 5 can be removed to take out the lower sleeve 8, and then the universal wheel 3 can be removed. The hollow cylinder can then be rotated around the axis and folded into a vertical position using the hinge seat 9. It can then be placed in the storage box or box and stacked with the middle connecting cylinder, upper sleeve 2, etc. for storage. At this point, the device is complete.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
