Description

Technical Field

[0001] The present invention belongs to the technical field of barcode scanners, and more specifically, particularly relates to a barcode scanner with a dust-proof fixing structure. Background Art

[0002] In the fields of logistics freight, warehousing, retail, and industrial production, it is often necessary to use scanners to collect data; for example, in logistics freight, in order to ensure the accurate tracking and management of goods, barcodes are often pasted on the goods; at this time, a barcode scanner is required to scan the barcode to achieve the warehousing operation of the goods, facilitate the recording of goods information, and ensure the real-time update of inventory data.

[0003] However, in a logistics warehouse, the handling of goods often causes dust to be raised, making the dust fill the air; however, the scanning lens of a traditional barcode scanner is directly exposed to the outside. During the scanning process, since the emitted light illuminates the barcode, certain static electricity will be generated in the optical components inside the barcode scanner, and the dust itself is charged. Under the adsorption of static electricity, it is easy for the raised dust to be quickly adsorbed on the lens surface. After long-term use, it is easy to cause dust accumulation, which will not only affect the emission and reflection of light, resulting in a decrease in scanning accuracy, but also increase the risk of lens wear due to repeated wiping of the lens, thereby shortening the overall service life of the barcode scanner.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By arranging a dust-proof frame and a dust-proof lens, a dust-proof cavity is formed at one end of the gun head, isolating the scanning lens from the outside world, effectively preventing dust from directly adsorbing on the scanning lens. A sealing strip is arranged between the dust-proof frame and the dust-proof lens to further enhance the sealing effect and reduce the entry of dust. Moreover, the dust-proof frame is detachably connected to the gun head through screws, and the dust-proof lens is detachably connected through a connecting sleeve, a connecting pin and a first magnet on the first connection block, which is convenient for cleaning and maintaining the dust-proof component. At the same time, the sandwich lens arranged in the dust-proof cavity, with optical silicone oil filled in the sandwich, can not only optimize the light propagation path, improve the scanning accuracy, but also buffer the possible entering dust to a certain extent, prevent it from directly impacting the scanning lens, improve the dust-proof performance of the scanning gun, reduce the influence of dust accumulation on light emission and reflection, and ensure the accuracy and stability of the scanning work.

[0018] 2. The heat dissipation air duct and ventilation slots provided inside the gun body, together with the heat dissipation guide plate and heat dissipation fins in the installation cavity, form an effective heat dissipation path, accelerating air circulation and taking away the heat generated by the operation of the component module. The cooling block and liquid cooling plate equipped with the scanning gun, and the zigzag liquid cooling channel in the liquid cooling plate can efficiently absorb heat. The cold air cavity of the cooling block forms a path through the connecting pipe and the connection port on the first connecting piece, further enhancing the heat dissipation effect. The heat conducting plate in the cooling box divides it into a storage cavity and an air cooling cavity. The second fan takes in air from the air cooling cavity, and multiple water pumps connect the storage cavity and the connection head of the second connecting piece on the gun body, enabling the coolant in the storage cavity to circulate to the liquid cooling plate to achieve efficient heat dissipation. The heat conducting ribs on the heat conducting plate increase the heat dissipation area, extending from the top to the bottom of the cooling box and being separated from the bottom surface of the air cooling cavity, optimizing the heat dissipation structure, ensuring that the internal components of the scanning gun are always at an appropriate temperature during long-term operation, extending the service life of the equipment, and improving the working stability.

[0019] 3. On the fixed platform, through the electric cylinder and sliding rail structure on the mounting seat, the dust-proof lens can be removed from the scanning gun and moved from the feeding area to the discharging area, and the dust-proof lens is clamped on the fixed frame. The fixed frame has the same structure as that on the dust-proof frame, enabling the dust-proof lens to be quickly disassembled and installed on the dust-proof frame and the fixed frame; the cleaning box on one side of the fixed platform is used to clean the dust-proof lens. When the dust-proof lens is clamped on the fixed frame, it is moved to the cleaning area through the second electric slider. The cleaning frames on both sides of the cleaning box are connected to the cleaning cross frame through the sliding rail structure, and the electric lifting rod at the bottom of the cleaning cross frame can adjust the height. The second electromagnet at the telescopic end of the electric lifting rod cooperates with the third magnetic plates on both sides of the fixed frame, which can stably adsorb the fixed frame, facilitating the cleaning of the dust-proof lens placed on it. The first fan on the cleaning box sends air to the air box through the conduit, and the air outlet of the air box faces the access slot, which can quickly dry the dust-proof lens after cleaning. The probe at the bottom of the ultrasonic generator penetrates into the cleaning box, and it can use ultrasonic vibration to more efficiently remove stubborn stains on the dust-proof lens.

Detailed implementation manners

[0035] The following further describes in detail the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the technical solutions of the present invention, but cannot be used to limit the protection scope of the present invention.

[0036] Embodiment 1:

[0037] As Figures 1 to 13As shown in the figure, the present invention provides a barcode scanner with a dust-proof fixing structure, which includes a barcode scanner body and a fixing component for placing it. The body 11 of the barcode scanner is divided into two major parts: the gun head and the grip. A cover plate 12 is covered on the gun head, and the two cooperate with each other to form an installation cavity. In this installation cavity, a component module 21 is placed. The component module 21 is a module that integrates all the components required for the barcode scanner, so as to realize a series of basic functions such as the collection, conversion, processing of barcode information of the barcode scanner and data interaction with external devices. At the same time, a dust-proof net 13 is also provided in the installation cavity, which can initially block the entry of external dust and prevent dust from affecting components such as the component module 21. In addition, a sealing ring 14 is provided at the bottom of the cover plate 12, which further improves the sealing performance of the installation cavity and reduces the possibility of dust intrusion. A dust-proof frame 301 and a dust-proof lens 302 are provided at one end of the gun head. The dust-proof frame 301, the dust-proof lens 302 and the body 11 together form a dust-proof cavity. The scanning lens 22 is installed on the gun head. One side of it faces the dust-proof cavity, which can avoid being directly exposed to the external environment and being contaminated with dust. The other side faces the installation cavity and is connected to the component module 21, so that the information obtained by the scanning lens 22 can be transmitted to the component module 21 in time for processing. At the bottom of the grip, a battery compartment is provided, and a storage battery 23 is placed in the battery compartment to provide power support for the operation of the entire barcode scanner. The fixing component is composed of a fixing table 401 and a fixing seat 402. A support frame 403 is provided on the fixing table 401, and the fixing seat 402 is connected to the support frame 403. In actual use, the gun head at one end of the barcode scanner can be conveniently clamped in the fixing seat 402 to realize the stable placement of the barcode scanner and avoid accidental situations such as collision and falling of the barcode scanner when it is not in use. For example, in the complex working environment of a warehouse, if placed randomly, the barcode scanner is easily knocked down by the goods being transported, resulting in damage to internal components. By fixing with the fixing seat 402, such risks can be effectively reduced, ensuring that the barcode scanner can be used normally at any time; at the same time, a controller is also provided in the fixing table 401, and through the controller, precise control of each part of the device can be realized, such as controlling the movement of the fixing seat 402 and starting the cleaning process of the cleaning box 81. At the same time, the component module 21 inside the barcode scanner is also connected to the controller through a wireless module provided inside, which can transmit the scanning data to the controller in time and can also receive the instructions issued by the controller to ensure the coordinated operation of the barcode scanner and the fixing component.

[0038] As Figure 1 , Figure 2 , Figure 11As shown, the dust-proof frame 301 is directly clamped inside the gun head at one end of the scanning gun and is detachably connected to the gun head through screws. A dust-proof lens 302 is sleeved at the other end of the dust-proof frame 301, building an important dust-proof barrier for the scanning lens 22. Connecting sleeves 303 are provided on both sides of the dust-proof lens 302, and movable connecting pins 304 are arranged inside the connecting sleeves 303. At the same time, first connecting blocks 305 are correspondingly provided on both sides of the dust-proof frame 301. First connecting holes are opened on the first connecting blocks 305, and first magnets are arranged at one end of the holes. The connecting pins 304 are inserted into the first connecting holes, and one end of the connecting pins 304 can contact the first magnets, realizing the detachable connection between the dust-proof lens 302 and the dust-proof frame 301. When it is necessary to clean or replace the dust-proof lens 302, just pull out the connecting pins 304 from the first connecting holes, and the first magnets release the attraction to the connecting pins 304, thus releasing the fixation of the dust-proof lens 302, and the dust-proof lens 302 can be easily removed. To further improve the dust-proof effect, sealing strips are provided on both the dust-proof frame 301 and the dust-proof lens 302. These sealing strips are distributed at the gaps between the dust-proof frame 301 and the dust-proof lens 302, effectively reducing the possibility of dust entering the dust-proof cavity from the gaps. Inside the dust-proof frame 301, a connecting frame 306 is further provided, and an interlayer lens 307 is arranged inside the dust-proof cavity. The interlayer lens 307 is firmly clamped inside the connecting frame 306 and is exactly located on the scanning path of the scanning lens 22. An interlayer is provided inside the interlayer lens 307, and optical silicone oil is filled in the interlayer. It can not only optimize the light to a certain extent, making the image obtained by the scanning lens 22 clearer, but also buffer the dust that may enter the dust-proof cavity to a certain extent, preventing the dust from directly impacting the scanning lens 22 and ensuring the normal operation of the scanning gun in all aspects.

[0039] Inside the dust-proof cavity of the barcode scanner, multiple groups of laser sensors 308 are provided. These laser sensors 308 are all installed on the gun head and are symmetrically distributed in a circular pattern along the scanning lens 22. With this layout, the irradiation ends of the laser sensors 308 can face the dust-proof lens 302 in all directions. When dust adheres to the dust-proof lens 302, the situation of the reflected light will change after the laser emitted by the laser sensor 308 encounters the dust. The laser sensor 308 can capture these changes and transmit relevant signals. A processing module 309 is provided in the installation cavity and is respectively connected to multiple groups of laser sensors 308. After receiving the signals transmitted by the laser sensors 308, the processing module 309 will analyze and process them. Once it detects that the dust amount on the dust-proof lens 302 reaches a certain level, the processing module 309 will issue an instruction. The processing module 309 is a common module without a specified model. At the same time, a warning light and a buzzer are also equipped on the gun head. After the processing module 309 issues an instruction, the warning light starts to flash and the buzzer will also make a sound to remind the user that the dust-proof lens 302 needs to be cleaned, thus ensuring the normal scanning effect of the barcode scanner. The laser sensor 308 can adopt the Omron E3Z-LT61 laser sensor.

[0040] Working logic of the laser sensor 308: When the barcode scanner is first activated, the laser sensor 308 emits a laser beam towards the clean dust-proof lens 302. At this time, the sensor records the reference intensity value I0 of the reflected light and the reflected light angle range θ. n Since the surface of the dust-proof lens 302 is flat and there is no dust, the reflected light is relatively concentrated and the intensity is stable.

[0041] Real-time detection stage: During the normal operation of the barcode scanner, the laser sensor 308 continuously emits laser towards the dust-proof lens 302. When dust adheres to the lens, the dust particles will cause the laser to scatter and diffuse reflect. The sensor real-time collects the intensity value In of the reflected light and the reflected light angle range θ. n Here, n represents the time sequence of each detection.

[0042] After collecting the above data, the processing module 309 performs an analysis algorithm and calculates the dust interference coefficient: The processing module 309 first calculates the reflected light intensity change coefficient C. I and the reflected light angle change coefficient C. θ .

[0043] Reflected light intensity change coefficient This coefficient reflects the change degree of the reflected light intensity relative to the reference state.

[0044] Reflected light angle change coefficient It is used to measure the change situation of the reflected light angle range. The more dust there is, the more severe the scattering is, and the reflected light angle range will increase significantly.

[0045] In order to more accurately evaluate the amount of dust on the dust-proof lens 302, the processing module 309 calculates the dust amount index D in a weighted synthesis manner. After a large number of experiments and data analyses, the weight ω of the intensity change coefficient is determined I = 0.6, and the weight ω of the angle change coefficient θ = 0.4. Then the dust amount index D = ω I C I + ω θ C θ .

[0046] Finally, threshold judgment and instruction issuance: The processing module 309 has preset a threshold M for the dust amount. When the calculated dust amount index D ≥ M, the processing module 309 determines that the amount of dust on the dust-proof lens 302 has reached the level that needs to be cleaned, and then issues instructions to the warning light and the buzzer. The warning light starts to flash at a specific frequency, flashing 3 times per second, and the buzzer emits intermittent short beeps, beeping for 1 second every 2 seconds, so as to attract the user's attention and prompt to clean the dust-proof lens 302 to ensure that the scanner maintains good scanning performance.

[0047] Multiple groups of partition ribs 310 are evenly distributed on the inner wall of the installation cavity. The component module 21 is clamped between multiple groups of partition ribs 310, and a gap is formed between the component module 21 and the inner wall of the installation cavity through these partition ribs 310. Don't underestimate this gap, it has an important impact on the performance of the scanner. When the scanner is working, the component module 21 will generate heat. The existence of the gap is conducive to the flow of air around the component module 21, playing a role in preliminary heat dissipation. Both sides of the gun head are provided with heat dissipation air ducts 15 and ventilation slots 16. The installation cavity is interconnected with the heat dissipation air ducts 15 through the ventilation slots 16 to form a complete heat dissipation path. Multiple groups of heat dissipation guide plates 311 are also arranged in the installation cavity. One side of the heat dissipation guide plates 311 is distributed with multiple groups of heat dissipation fins 312. Multiple groups of heat dissipation fins 312 pass through the ventilation slots 16 and are located in the heat dissipation air ducts 15, and the heat dissipation fins 312 are arranged horizontally, and their extending direction is consistent with that of the heat dissipation air ducts 15. When the scanner generates heat during operation, the hot air will rise and enter the heat dissipation air ducts 15 through the ventilation slots 16. The heat dissipation fins 312 can increase the contact area with the air, accelerate air convection, quickly take out the hot air, and the cold air is continuously replenished from the outside, so as to effectively dissipate the heat inside the scanner, especially the component module 21, and ensure that the internal components of the scanner are always in a suitable temperature environment and operate stably during long-term operation.

[0048] The barcode scanner further includes a cooling block 51 and a liquid cooling plate 52. A card slot 53 is pre-opened on the gun body 11, and the cooling block 51 can be clamped in the card slot 53 to achieve preliminary fixation with the gun body 11. The cooling block 51 itself also has a unique structure, on which an installation card slot 54 is opened, and the liquid cooling plate 52 is clamped in this installation card slot 54. A liquid cooling channel is arranged inside the liquid cooling plate 52, and the liquid cooling channel is arranged in a zigzag shape. This zigzag design increases the flow path of the coolant in the liquid cooling plate 52, extends the contact time between the coolant and the liquid cooling plate 52 and surrounding components, and thus improves the heat dissipation efficiency. A cold air cavity is also opened inside the cooling block 51, and an air outlet is opened on the surface of the cooling block 51. The cold air cavity communicates directly with the external environment through this air outlet to ensure the air pressure in the cold air cavity; at the same time, the cold air cavity is connected to an external cold air system through a first connector 55, so as to cool the coolant in the liquid cooling channel through the cold air in the cold air cavity, and there is no need to frequently circulate and replace the coolant in the liquid cooling channel. A first connector 55 is arranged on one side of the gun body 11, and a connecting ring 56 is equipped on the first connector 55. The connecting ring 56 is in a ring structure and is sleeved on the cooling block 51 and the grip part, playing a role in further stabilizing the connection between the cooling block 51 and the gun body 11. Multiple groups of connection ports 57 are arranged on the first connector 55, and one group of connection ports 57 is connected to the cold air cavity through a connecting pipe. In this way, when the external environmental temperature is relatively low or rapid heat dissipation is required, an external device can be connected through the connecting pipe to blow cold air into the cold air cavity to enhance the cooling effect. The other multiple groups of connection ports 57 are respectively connected to both ends of the liquid cooling channel of the liquid cooling plate 52 to build a complete coolant circulation path. When the barcode scanner works and generates heat, the coolant flows out from one end of the liquid cooling channel, passes through components such as the connection port 57 and the connecting pipe, and is transported to an external cooling device (if there is an external connection) or cooled naturally, and then flows back into the liquid cooling channel of the liquid cooling plate 52 from the connection port 57 at the other end, continuously taking away the heat generated inside the barcode scanner, ensuring that the barcode scanner is always in a good working temperature state, maintaining its stable operation, and reducing the probability of performance degradation or failure caused by overheating.

[0049] Such as Figure 3 , Figure 4 , Figure 7 , Figure 12As shown in the figure, multiple arc-shaped frames 404 are provided on the support frame 403, and these arc-shaped frames 404 provide an orbital foundation for the movement of the fixed seat 402. A guide rail groove 405 is provided on the surface of the arc-shaped frame 404. Electric pulleys 406 and multiple limit wheels 407 are respectively installed on both sides of the fixed seat 402. The electric pulley 406 can be clamped in the guide rail groove 405. When the electric pulley 406 is powered on and operates, it drives the fixed seat 402 to move along the guide rail groove 405, thereby realizing the slidable connection between the fixed seat 402 and the support frame 403. The limit wheels 407 are in contact with the arc-shaped frame 404, playing a role in stabilizing the fixed seat 402 and preventing it from shaking or shifting during the movement. A moving area is demarcated on the arc-shaped frame 404, and a replacement area is provided at the end of the moving area. The fixed seat 402 is located in this replacement area. When maintenance or component replacement of the fixed seat 402 is required, it can be moved to the replacement area for easy operation. A support plate 408 is provided above the fixed table 401, and the support plate 408 is connected to the fixed table 401 through a slide rail structure, which enables the support plate 408 to slide on the fixed table 401. A material taking area and a material discharging area are respectively provided on the traveling path of the slide rail structure. An installation seat 409 and an electric cylinder 410 are installed above the support plate 408. The installation seat 409 is connected to the support plate 408, providing installation support for the electric cylinder 410. The electric cylinder 410 is connected to the installation seat 409 in a rotatable manner, and this connection endows the electric cylinder 410 with a certain degree of rotationality. Multiple first electromagnets 411 and electric suction cups 412 are provided at the shaft end of the electric cylinder 410. The electric suction cup 412 is located between multiple first electromagnets 411, and both the first electromagnets 411 and the electric suction cups 412 can contact the dust-proof lens 302. When the dust-proof lens 302 needs to be operated, such as removing it from the scanning gun for cleaning or replacement, the electric cylinder 410 can extend its shaft end and use the magnetic force generated by the energization of the first electromagnets 411 or the adsorption force of the electric suction cups 412 to grasp the dust-proof lens 302.

[0050] A coupling 61 is provided on the mounting base 409. The electric cylinder 410 is connected to the coupling 61 through a first connecting rod, so that the power of the electric cylinder 410 can be transmitted to the coupling 61 through the first connecting rod. A limiting groove is formed on the fixed table 401. A second connecting rod is provided on one side of the rotating gear 62. The second connecting rod passes through the limiting groove and is connected to the coupling 61. When the electric cylinder 410 operates, its power is transmitted to the coupling 61 through the first connecting rod, and then drives the rotating gear 62 to rotate synchronously. An adjustment area and a limiting area are also provided on the fixed table 401. The material taking area is located in the adjustment area, and the material discharging area is located in the limiting area. In the adjustment area, a rotating rack 63 is installed. The rotating gear 62 meshes with the rotating rack 63. When the rotating gear 62 rotates, due to its meshing relationship with the rotating rack 63, components such as the electric cylinder 410 and the mounting base 409 will move along the adjustment area on the fixed table 401, facilitating operations on components such as the dust-proof lens 302 in the material taking area. In the limiting area, a slide bar 64 is provided on the fixed table 401. One end of the limiting frame 65 is slidably connected to the slide bar 64. A spring is provided between the limiting frame 65 and the fixed table 401. The spring is sleeved on the slide bar 64. The other end of the limiting frame 65 is provided with a first magnetic attraction plate 66, and a second magnetic attraction plate 67 is provided on one side of the electric cylinder 410. When the electric cylinder 410 moves to the limiting area, the first magnetic attraction plate 66 can contact the second magnetic attraction plate 67, and the first magnetic attraction plate 66 can also contact the mounting base 409. When the electric cylinder 410 moves to the material discharging area, the magnetic attraction effect can be used to limit and fix it, and it also helps to control the position of the electric cylinder 410 in the material discharging area, ensuring the smooth progress of related operations. For example, when performing the material discharging operation on the dust-proof lens 302, it can be accurately placed at the designated position in the material discharging area.

[0051] Such as Figure 4 , Figure 5 , Figure 7 , Figure 8As shown in the figure, a moving slide rail 413 is provided on one side of the fixed table 401. An electric slider is installed on the moving slide rail 413 and can move along the rail. The entire moving slide rail 413 is divided into a blanking area and a cleaning area, and different areas undertake different functions. An installation plate 701 is fixed on the electric slider. Multiple groups of limiting blocks 702 are arranged on the installation plate 701. Multiple groups of fixing frames 703 are respectively clamped between the multiple groups of limiting blocks 702. Such a setting enables the fixing frames 703 to be stably placed on the installation plate 701. On one side of the installation plate 701, corresponding to the position of the fixing frame 703, multiple groups of fixing buckles 704 are rotatably installed, and a flip spring is also provided at the connection. When it is necessary to fix the fixing frame 703, the fixing buckle 704 can be clamped on the fixing frame 703, and the flip spring provides a certain elastic force to ensure that the fixing buckle 704 can clamp the fixing frame 703. An adjusting roller 705 is also arranged on one side of the fixing buckle 704. At the same time, an adjusting block 706 is installed on the fixed table 401. One side of the adjusting block 706 is arc-shaped. When the installation plate 701 moves to the cleaning area, the adjusting roller 705 can contact the arc-shaped side of the adjusting block 706. As the installation plate 701 moves, the adjusting roller 705 rolls on the arc-shaped surface of the adjusting block 706. During this process, the fixing buckle 704 will be pushed to rotate, so that the fixing effect of the fixing buckle 704 on the fixing frame 703 is released to better meet the cleaning requirements.

[0052] A plurality of second connection blocks 713 are provided on the fixing bracket 703. Second connection holes are formed in the second connection blocks 713, and second magnets are further installed at the bottom. When the dust-proof lens 302 is installed on the fixing bracket 703, the connection pins 304 will pass through the second connection holes and contact the second magnets, thereby realizing the positioning installation of the fixing bracket 703 and the dust-proof lens 302. A cleaning box 81 is provided at the position of the cleaning area on the fixing table 401. Cleaning racks 82 are equipped on both sides of the cleaning box 81. The cleaning cross-rack 83 is connected to the plurality of cleaning racks 82 through a slide rail structure, which allows the cleaning cross-rack 83 to move along the cleaning racks 82. An electric lifting rod 84 is installed at the bottom of the cleaning cross-rack 83. Third magnetic attraction plates 707 are provided on both sides of the fixing bracket 703. A second electromagnet is provided at the telescopic end of the electric lifting rod 84 corresponding to the third magnetic attraction plates 707. When the fixing bracket 703 needs to be operated, the electric lifting rod 84 extends and retracts, and the second electromagnet approaches and contacts the third magnetic attraction plates 707, and the fixing bracket 703 is fixed by using magnetic force, facilitating subsequent cleaning work. An access slot 85 is formed on the cleaning box 81, and an air box 86 is provided inside the box. The air outlet of the air box 86 faces the access slot 85 directly; a first blower 87 and an ultrasonic generator 88 are further installed on the cleaning box 81. The first blower 87 is connected to the air box 86 through a conduit. After the cleaning is completed, the first blower 87 is started, and air is sent to the air box 86 through the conduit. The air blows out from the air outlet of the air box 86 and passes through the access slot 85, which can quickly dry the fixing bracket 703 and the components thereon. The probe at the bottom of the ultrasonic generator 88 passes through the cleaning box 81. When the ultrasonic generator 88 is turned on, the ultrasonic vibration generated by the probe can penetrate into the liquid in the cleaning box 81 to better remove the stains on the fixing bracket 703 and related components, ensuring the cleaning effect. The ultrasonic generator 88 can adopt a 7KHZ - 40KHZ sweep frequency ultrasonic cleaning power generator.

[0053] Such as Figure 4 , Figure 9 , Figure 10As shown, a cooling box 91 is placed on one side of the fixed platform 401, and multiple groups of heat conducting plates 92 are arranged inside the cooling box 91. These heat conducting plates 92 divide the cooling box 91 into two groups of storage chambers and air cooling chambers. One group of storage chambers is used to store coolant, and the other group of storage chambers is used to receive coolant after circulation in the liquid cooling channel, so as to realize the replacement of coolant in the liquid cooling channel; multiple groups of air inlet slots are opened on both sides of the cooling box 91, and the air cooling chamber is directly connected to the outside air through these air inlet slots, and the outside cold air can smoothly enter the air cooling chamber. The cooling box 91 is equipped with a second fan 93 and multiple groups of water pumps 94. The air inlet of the second fan 93 faces the inside of the air cooling chamber. When the second fan 93 is started, it can accelerate the air flow in the air cooling chamber, and suck the air at the bottom of the air cooling chamber to the top. In the process of rising, the air passes through the heat conducting plates 92 on both sides. A second connector 95 is provided on one side of the gun body 11, and a plurality of connectors 96 are provided on the second connector 95. These connectors 96 can be stuck in the connection port 57 of the first connector 55, so that the first connector 55 and the second connector 95 can be detachably connected. The plurality of water pumps 94 are respectively connected to the plurality of storage chambers and the plurality of connectors 96 therein through connecting pipes. Under the action of the water pumps 94, the coolant in the storage chamber is transported to the liquid cooling plate 52 in the scanning gun through the connecting pipes, the connectors 96 and other components, thereby taking away the heat generated by the operation of the scanning gun, and then transporting the coolant from the liquid cooling plate 52 to the storage chamber. A flow sensor is provided on the connecting pipe to monitor the flow of the coolant and detect whether the coolant in the liquid cooling channel has been extracted and replenished. The second fan 93 is connected to another group of connectors 96, and the air in the air cooling chamber is transported to the cold air chamber through the second fan 93. Multiple groups of heat-conducting ribs 97 are arranged on the corresponding surfaces of the multiple groups of heat-conducting plates 92. These heat-conducting ribs 97 extend from the top to the bottom of the cooling box 91, effectively increasing the heat dissipation area of ​​the heat-conducting plates 92. At the same time, the heat-conducting ribs 97 are separated from the bottom surface of the air-cooling cavity, which optimizes the air flow path in the air-cooling cavity, making the heat dissipation process more efficient, and ensuring that the scanner is always at a suitable working temperature and operates stably.

[0054] Embodiment 2:

[0055] Based on the scanning gun with a dustproof fixing structure provided in the first embodiment of the present application, the second embodiment of the present application proposes a scanning gun with a dustproof fixing structure. This second embodiment is only a preferred method of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment. The second embodiment of the present invention will be further described below.

[0056] like Figure 6As shown in the figure, on one side of the fixed table 401, the moving slide rail 413 extends longitudinally. An electric slider is arranged on the slide rail and can slide freely on the moving slide rail 413. The moving slide rail 413 is clearly divided into a blanking area and a cleaning area, corresponding to different working stages. The top of the electric slider is fixed with a mounting plate 701. On one side of the mounting plate 701, there is an adjustment frame 708. An adjustment rod 709 runs horizontally through the inside of the adjustment frame 708. The adjustment bracket 710 is slidably connected to the adjustment rod 709, and there is a spring-back structure on the adjustment rod 709. When the adjustment bracket 710 is pushed by an external force to slide on the adjustment rod 709 and the external force disappears, the spring-back structure will make it automatically reset. The top of the adjustment bracket 710 is installed with a rotatable adjustment support 711, and a flip spring is arranged at the connection between the two, which enables the adjustment support 711 to rotate. One end of the adjustment support 711 is installed with a pressing wheel 712. When placing the fixing frame 703, it can be clamped between the pressing wheel 712 and the mounting plate 701 to achieve preliminary fixation. On the same side of the mounting plate 701, corresponding to the position of the fixing frame 703, there are multiple groups of rotatable fixing buckles 704, and flip springs are arranged at their connections with the mounting plate 701. When the fixing frame 703 is placed in place, rotating the fixing buckle 704 can clamp it on the fixing frame 703 to further stabilize the fixing frame 703. One side of the fixing buckle 704 is provided with an adjustment roller 705, and on the fixed table 401, at the position of the cleaning area, there is an adjustment block 706, and one side of the adjustment block 706 is arc-shaped. When the mounting plate 701 moves to the cleaning area, the adjustment roller 705 will contact the arc-shaped side of the adjustment block 706. As the mounting plate 701 moves, the adjustment roller 705 rolls on the arc-shaped surface of the adjustment block 706. During this process, it will push the fixing buckle 704 to rotate, so that the fixing buckle 704 releases the fixing effect on the fixing frame 703 to better meet the cleaning requirements.

[0057] The difference between the second embodiment and the first embodiment is that an adjustment frame 708 is added to one side of the mounting plate 701. The adjustment frame 708 is provided with a horizontally penetrating adjustment rod 709. The adjustment bracket 710 is slidably connected to the adjustment rod 709 and there is a spring-back structure on the adjustment rod 709. The top of the adjustment bracket 710 is installed with a rotatable adjustment support 711, and a flip spring is arranged at the connection between the two. One end of the adjustment support 711 is installed with a pressing wheel 712. This series of structures enables the fixing frame 703 to be preliminarily fixed and adjusted in multiple directions when placing the fixing frame 703 through the sliding of the adjustment bracket 710, the rotation of the adjustment support 711, and the action of the pressing wheel 712. Thus, through the pressing wheel 712 and the fixing buckle 704, the balanced fixation of both sides of the fixing frame 703 can be achieved, effectively preventing the fixing frame 703 from tilting or displacing during use. At the same time, it will not prevent the dust-proof lens 302 from being cleaned and the fixing frame 703 from being smoothly installed on the mounting plate 701. The remaining conditions are the same as those in the first embodiment, so this embodiment will not be elaborated further.

[0058] The foregoing has shown and described the basic principles, main features and advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments.
