Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of code scanner, especially relates to a code scanner waterproof structure. BACKGROUND

[0002] As an important device widely used in commercial, logistics, retail and other fields, the performance requirements of code scanner are constantly improving, especially in terms of waterproof, dustproof and other aspects. With the continuous progress of technology and the increasing complexity of application environment, the waterproof performance of code scanner has become one of the key indicators, especially in scenarios that require IP67 level waterproof standard. IP67 level means that the device can completely prevent dust from entering and can withstand short-term immersion, usually 30 minutes at 1 meter depth. Meeting this standard poses a high technical challenge to the design of code scanner.

[0003] In the existing design of code scanner, waterproof technology generally relies on strict sealing treatment of the device shell. The most common waterproof methods include using waterproof sealing rings, coating waterproof coatings, using special glue bonding and other means. However, these traditional waterproof methods have certain limitations. First, many traditional waterproof technologies are prone to failure due to environmental factors during long-term use. For example, in high temperature, low temperature or humid environment, common glue and sealing materials may age, crack or have reduced adhesion strength, causing water or dust to enter the device, reducing the reliability and durability of the code scanner. Especially in scenarios with large temperature difference, the performance of the glue may be greatly affected, and the sealing performance cannot be maintained for a long time. Second, the connection between the shell and the internal components of the code scanner is a weak link in waterproof design. Many code scanners use traditional threaded connections or simple interface designs, which cannot provide long-term effective waterproof performance, especially in the case of frequent plugging or vibration, which can easily cause sealing to be not tight or the interface to be loose, allowing water or dust to enter the device and affect the normal operation of the device. In addition, the circuit board, sensors and other precision components inside the code scanner are extremely sensitive to water, which can cause short circuits or corrosion after water enters, affecting the stability of the code scanner and even causing device failure.

[0004] In order to solve these problems, more and more code scanner designs begin to focus on optimizing from the aspects of structure design, material selection and manufacturing process. However, in the field of waterproof design of code scanner, there are still many technical challenges. For example, how to ensure waterproof performance while not affecting the use experience and operation convenience of the code scanner, how to improve waterproof effect through innovative materials and new sealing technology, how to design a shell structure that can be waterproof without increasing the weight and volume of the device, all of which require more in-depth research and technical breakthroughs. SUMMARY

[0005] To solve the problem of glass fogging, and realize the IP67 level waterproof of the code scanner, the utility model provides a code scanner waterproof structure, specifically, the utility model provides the technical scheme as follows:

[0006] A code scanner waterproof structure, including code scanner module and the connecting line protection structure connected with code scanner module, the code scanner module is built in the code scanning component, the connecting line protection structure is used to accommodate the protection and the code scanning component is connected code scanner connecting line, the code scanner module includes the upper shell and the lower shell of fastening connection, the upper shell is provided with the point glue groove for uniform coating of glue, the point glue groove is tightly bonded with transparent glass, the transparent glass adopts the tempered glass, and the lamination surface of the tempered glass and the upper shell is provided with high temperature ink.

[0007] Further, the transparent glass is provided with an anti-fog coating on the side facing the code scanning component.

[0008] Preferably, the surface of the high temperature ink has a surface energy value of 36 or more.

[0009] Further, waterproof sealing silica gel is provided between the lower shell and the upper shell, and a plurality of protruding structure compression ribs are additionally provided on the contact surface of the upper shell and the waterproof sealing silica gel.

[0010] Further, the connecting line protection structure is connected to the code scanner module at one end by ultrasonic welding, and the other end of the connecting line protection structure is connected to the code scanner module by a waterproof joint.

[0011] Further, a plurality of accommodation spaces for storing desiccant are also provided in the lower shell.

[0012] Compared with the prior art, the code scanner waterproof structure provided by the utility model has significant advantages in many aspects, particularly in the improvement of waterproof performance and the stability of the structure:

[0013] Firstly, the code scanner module adopts a fastening connection design of the lower shell and the upper shell, and the code scanning component is integrated inside. This structure sets waterproof sealing silica gel between the lower shell and the upper shell, not only effectively prevents the penetration of water and dust, but also enhances the tightness of the overall structure. The waterproof sealing silica gel plays a key sealing role between the two shells, can maintain stability for a long time, and can maintain its waterproof performance when temperature changes. In order to further improve the waterproof effect of the connection part, a plurality of protruding structure compression ribs are additionally provided on the contact surface of the upper shell and the waterproof sealing silica gel, which ensures sufficient contact between the upper shell and the silica gel, thereby preventing water from entering to the maximum extent.

[0014] In addition, the glue coating technology between the upper shell and the transparent glass is also optimized. A glue groove is arranged in the upper shell, and the high-temperature-resistant and corrosion-resistant glue is uniformly coated through the groove, so that the bonding between the transparent glass and the upper shell is more firm. In particular, high-temperature ink is coated on the surface of the glass, which has stronger weather resistance and anti-aging performance, so as to ensure that the ink will not fall off or crack under harsh environments such as high temperature, low temperature or humid conditions, and further enhance the overall sealing performance and durability of the code scanner. The high-temperature ink not only increases the adhesion between the glass and the glue, but also improves the high-temperature resistance and chemical corrosion resistance of the glass surface, so that the service life of the code scanner in complex environments is prolonged.

[0015] The waterproof structure also tightly connects the connecting line protection structure and the code scanner module through ultrasonic welding technology, ensuring the water tightness of the connection. Compared with traditional screw connection or adhesive connection, ultrasonic welding has higher precision and strength, which not only improves the tightness of the connection, but also effectively avoids the water leakage problem caused by improper operation or poor sealing in traditional methods. The use of waterproof joints further enhances the waterproof capability, especially at the other end of the connecting line protection structure, ensuring that the interference of the external environment on the code scanner can be effectively isolated.

[0016] In summary, the waterproof structure of the code scanner effectively solves the problems of unstable waterproof performance, poor sealing and poor durability in the prior art by using a series of innovative technologies such as ultrasonic welding, waterproof joints, innovative sealing design, high- and low-temperature-resistant glue, desiccant storage space and anti-fog coating, greatly improving the reliability and service life of the code scanner in harsh environments. This design not only meets the requirements of IP67 waterproof level, but also ensures the stability and waterproofness of the code scanner in long-term use, especially in high-temperature, low-temperature and humid environments.
