Description

Technical Field

[0001] This utility model relates to the field of barcode scanning technology, and in particular to a barcode scanning device for preventing fogging in a cold storage room. Background Technology

[0002] A barcode scanning module is a device that uses light reflection to allow a camera to capture barcodes or QR codes and identify the corresponding data information. Scanning terminals are widely used in high-traffic areas, and the application of barcode scanning modules in these terminals is crucial and indispensable.

[0003] When the air humidity is high or the environment is freezing, the protective glass lens in front of the scanning module comes into contact with the air. Water vapor or cold air in the air condenses into water mist or frost on the glass lens. The water mist and frost block the camera of the scanning module, causing the QR code or barcode information to be incompletely collected, resulting in recognition errors, which affects the reliability of scanning and leads to unsatisfactory scanning results. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a cold storage anti-fog barcode scanning device, which facilitates anti-fog scanning in the cold storage room.

[0005] The technical solution of this utility model is as follows: a cold storage compartment anti-fog barcode scanning device, including a protective housing, a scanning module and an anti-fog module corresponding to the scanning module are arranged inside the protective housing, the scanning module includes a scanning camera, the anti-fog module includes a rotary motor and a baffle structure, the rotary motor is arranged inside the protective housing, the baffle structure is connected to the output end of the rotary motor, a scanning window corresponding to the scanning camera is arranged on the protective housing, the baffle structure is close to the scanning window, and the scanning window, the baffle structure and the scanning camera are located on the same axis.

[0006] As can be seen from the above scheme, the scanning module is used to scan barcode information, and the anti-fog module is used to drive the baffle structure to rotate through the rotary motor. The baffle structure achieves sealing by blocking the scanning window after rotation, and at the same time blocks the lens of the scanning camera to achieve anti-fog. This utility model does not require the use of electrically heated lens glass in front of the scanning camera, and the scanning does not pass through the glass, resulting in good scanning effect.

[0007] The protective shell has a window protector protruding from the scanning window. Therefore, the window protector is used to protect the scanning window.

[0008] The baffle structure includes a rotating shaft, a mounting block, and a baffle member. The mounting block is sleeved on the rotating shaft. The top end of the rotating shaft is connected to the protective housing, and the bottom end of the rotating shaft is connected to the output end of the rotary motor. The baffle member is connected to the mounting block and faces the scanning window. Therefore, the rotating shaft is used for hinged connection with the protective housing, and the mounting block is used for limiting the installation of the baffle member.

[0009] The inner side of the baffle component, facing the scanning window, is provided with a mounting groove, and the mounting groove is filled with insulating cotton. Therefore, the insulating cotton is used to seal the scanning window, preventing cold air from entering and thus achieving heat preservation.

[0010] The protective housing houses a scanner housing, which has an opening facing the scanning window. The scanning camera is mounted inside the scanner housing through this opening. Therefore, the scanner housing protects the scanning camera.

[0011] The protective housing has at least one set of waist-shaped mounting holes, and the scanner housing has a socket. Fasteners are inserted after the waist-shaped mounting holes are aligned with the sockets. Therefore, the different alignment positions of the sockets with the waist-shaped mounting holes are used to adjust the position of the scanning camera. Attached Figure Description

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] like Figures 1 to 4As shown, this utility model is a barcode scanning device for cold storage compartments to prevent fogging. It includes a protective housing 1, within which a scanning module and a corresponding anti-fog module are disposed. The scanning module includes a scanning camera 3, and the anti-fog module includes a rotary motor 4 and a baffle structure 5. The rotary motor 4 is disposed within the protective housing 1, and the baffle structure 5 is connected to the output end of the rotary motor 4. A scanning window 11 corresponding to the scanning camera 3 is provided on the protective housing 1, and the baffle structure 5 is flush with the scanning window 11. The scanning window 11, the baffle structure 5, and the scanning camera 3 are located on the same axis. In this embodiment, the scanning window 11 is a vertical, waist-shaped hole. A circuit board is disposed within the protective housing, and the scanning module and the anti-fog module are electrically connected to the circuit board.

[0015] The protective housing 1 has a window protector 12 protruding from the scanning window 11. In this embodiment, the scanning window 11 is provided as a through slot, and the window protector 12 is used to protect the scanning window 11 to prevent any obstruction from affecting the scanning results.

[0016] The baffle structure 5 includes a rotating shaft 51, a mounting block 52, and a baffle member 53. The mounting block 52 is sleeved on the rotating shaft 51. The top end of the rotating shaft 51 is connected to the protective housing 1, and the bottom end of the rotating shaft 51 is connected to the output end of the rotary motor 4. The baffle member 53 is connected to the mounting block 52 and is positioned facing the scanning window 11.

[0017] The inner side of the baffle 53 facing the scanning window 11 is provided with a mounting groove 531, and the mounting groove is filled with heat insulation cotton 6. In this embodiment, the depth of the mounting groove 531 is less than the thickness of the heat insulation cotton 6.

[0018] The protective housing 1 is provided with a scanner housing 2. The scanner housing 2 has an opening facing the scanning window 11, and the scanning camera 3 is installed in the scanner housing 1 through the opening.

[0019] The distance between the anti-fog module and the scanning module is greater than the width of the baffle 53, so as to avoid interference when the baffle 53 rotates.

[0020] The protective housing 1 is provided with at least one set of waist-shaped mounting holes 10, and the scanner housing 2 is provided with a socket 21. Fasteners are inserted after the waist-shaped mounting holes 10 are aligned with the socket 21. In this embodiment, three sets of waist-shaped mounting holes 10 are vertically arranged on the protective housing 1.

[0021] The working process of this utility model is as follows: When not scanning, the anti-fog module is in the closed state. This module will only be opened when scanning. When scanning, the rotary motor 4 drives the baffle 53 to rotate, and the channel connecting the scanning window 11 and the scanning camera 3 will be opened. When not in use, the baffle 53 blocks the scanning window 11 and seals it with heat insulation cotton, so that cold air will not come out and the scanning camera 3 will not have cold water, that is, it will not fog up, thus achieving anti-fog when scanning barcodes.

[0022] Finally, it should be emphasized that the above description is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
