Description

Technical Field

[0001] The utility model mainly relates to the technical field of insect traps, and in particular to an AGV trolley. Background Art

[0002] With the rapid development of science and technology, automated logistics systems play an increasingly important role in modern industrial production. As one of the core equipment of automated logistics, automatic guided vehicles (AGVs) are widely used in the handling, storage and distribution of various materials. However, when transporting materials that are extremely sensitive to the air environment, such as silicon wafers in battery workshops, traditional AGVs face severe challenges.

[0003] During the production process, the surface of the battery cell is easily corroded by harmful substances such as oxygen and moisture in the air, leading to oxidation problems and seriously affecting the performance of the product. Therefore, how to effectively isolate the air and prevent the battery cell from oxidation during transportation and storage has become a technical problem that needs to be solved urgently.

[0004] Traditional solutions often rely on external nitrogen sources, injecting nitrogen into the AGV through pipes or gas cylinders to maintain the purity of its internal environment. However, this method has many shortcomings, such as reduced flexibility due to reliance on external nitrogen sources.

[0005] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

[0007] The utility model provides an AGV vehicle to solve the technical problems existing in the above-mentioned background technology.

[0008] 2. Technical solution:

[0009] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is: an AGV car, comprising

A driving power source is arranged at one end of the gas cylinder. A charging and discharging mechanism is arranged at the other end of the gas cylinder. An outlet pipe of the charging and discharging mechanism is connected to the storage space.

[0013] The moving part of this device is a traditional AGV cart, which is used to perform preset movements on the loading mechanism at the top. This device is mainly used to load and transport silicon wafers for making solar panels. After the silicon wafers are placed in the storage space, the storage space is closed, and the gas charging and discharging mechanism at the top starts to perform the inflation operation. Nitrogen enters the storage space through the air outlet pipe, playing a protective role for the silicon wafers. It should be noted that this application can also be used for transporting other easily oxidizable objects, and other types of inert gases can be placed in the gas storage cylinder. This device is supplied with gas through the internal gas storage cylinder, with high flexibility, effectively isolating harmful substances such as oxygen and moisture in the air, thereby significantly reducing or eliminating the oxidation risk of sensitive materials such as silicon wafers and battery wafers during transportation. This not only protects the quality of the materials but also ensures that the performance of the products is not affected. As an inert gas, nitrogen has a good protective effect on materials such as metals. Maintaining a nitrogen environment inside the cart can not only protect the materials from oxidation but also slow down the corrosion rate of the metal components inside the cart to a certain extent, thereby extending the service life of the entire equipment and reducing the maintenance cost.

[0014] Further, the gas charging and discharging mechanism is provided with a pressure sensor.

[0015] Further, a sealing door is hinged to the front side of the loading mechanism. The sealing door encloses the storage space, and sealing rubber rings are provided on the four sides of the sealing door.

[0016] Further, the gas storage mechanism includes symmetrically arranged concave placement grooves. Threaded holes are opened at the top of the concave placement grooves, and the threaded holes are threadedly connected to clamping plates.

[0017] Further, air inlet joints are provided on both sides of the gas charging and discharging mechanism. The air inlet joints are connected to the gas storage cylinder. A gas replenishment port is provided at the top of the gas charging and discharging mechanism. A gas delivery chamber is provided inside the gas charging and discharging mechanism. An automatic valve is provided on the side of the gas delivery chamber, and the bottom of the gas delivery chamber communicates with the storage space.

[0018] Further, a gas delivery compartment is provided at the rear of the storage space. The gas delivery compartment is connected to the gas delivery chamber, and air inlet holes are spaced apart inside the gas delivery compartment.

[0019] Further, a fixed frame is provided at the top of the moving part. A plug-in block is provided at the bottom of the loading mechanism, and the plug-in block is detachably connected to the fixed frame.

[0020] 3. Beneficial effects:

[0021] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0022] The utility model has a reasonable design. The nitrogen gas storage bottle of the device is directly installed on the top of the gas storage mechanism and moves with the movement of the moving part, so that the silicon wafers transported inside can be well protected by nitrogen.

[0023] By setting up the air delivery compartment, nitrogen can be released evenly and stably into the interior of the trolley to maintain a suitable nitrogen environment;

[0024] The gas storage mechanism is powered independently, does not require power for the moving parts, and is detachable, making it easier to transport and unload silicon wafers.

[0025] It should be noted that the structures not introduced in the present invention are not related to the design points and improvement directions of the present invention, and are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.

[0036] Referring to the attached Figures 1-4 , an AGV cart, comprising

[0037] A moving part 1 for providing driving force to the entire device;

[0038] A loading mechanism 2 is arranged on the top of the moving part 1. A storage space 3 is arranged inside the loading mechanism 2 for storing the conveyed items.

[0039] A gas storage mechanism 4 is arranged on the top of the loading mechanism 2. A gas cylinder 5 is arranged inside the gas storage mechanism 4. One end of the gas cylinder 5 is provided with a driving power source 6, and the other end of the gas cylinder 5 is provided with a gas charging and discharging mechanism 7. The outlet pipe of the gas charging and discharging mechanism 7 is connected to the storage space 3.

[0040] The moving part 1 of this device is a traditional AGV cart, which is used to perform preset movements on the loading mechanism 2 at the top. This device is mainly used to load and transport silicon wafers for making solar panels. After the silicon wafers are placed in the storage space 3, the storage space 3 is closed, and the gas charging and discharging mechanism 7 at the top starts the inflation operation. Nitrogen enters the storage space 3 through the air outlet pipe, playing a protective role for the silicon wafers. It should be noted that this application can also be used for transporting other easily oxidized objects. Other types of inert gases can be placed in the gas storage cylinder 5. This device is supplied with gas through the internal gas storage cylinder 5, with high flexibility, effectively isolating harmful substances such as oxygen and moisture in the air, thereby significantly reducing or eliminating the oxidation risk of sensitive materials such as silicon wafers and battery wafers during transportation. This not only protects the quality of the materials but also ensures that the performance of the products is not affected. As an inert gas, nitrogen has a good protective effect on materials such as metals. Maintaining a nitrogen environment inside the cart can not only protect the materials from oxidation but also slow down the corrosion rate of the metal components inside the cart to a certain extent, thereby extending the service life of the entire equipment and reducing the maintenance cost.

[0041] The gas charging and discharging mechanism 7 is equipped with a pressure sensor, which can measure the pressure inside the gas storage cylinder 5. When the internal nitrogen pressure in the gas storage cylinder 5 is low, it indicates that nitrogen needs to be replenished. At this time, after receiving this signal, the moving part 1 at the bottom goes to the nitrogen filling place in time to replenish nitrogen. This not only reduces the time and cost of manual operation but also improves the continuity and efficiency of the transportation process, making the operation of the entire nitrogen protection system more accurate and reliable, and further enhancing the automation level of the cart.

[0042] A sealing door 21 is hinged to the front side of the loading mechanism 2. The storage space 3 is inside the sealing door 21. Sealing rubber rings are provided on the four sides of the sealing door 21. The sealing door 21 is opened and then closed when the silicon wafers are placed. The sealing rubber rings improve the tightness of the sealing door 21.

[0043] The gas storage mechanism 4 includes symmetrically arranged concave placement grooves 41. Threaded holes 42 are opened at the top of the concave placement grooves 41. The threaded holes 42 are threadedly connected to clamping plates 43. The gas storage cylinders 5 can be placed in the concave placement grooves 41 and then fixed by the clamping plates 43. The clamping plates 43 can be disassembled by screws when the gas storage cylinders 5 need to be replaced or repaired, facilitating the repair and replacement of the gas storage cylinders.

[0044] On both sides of the air charging and discharging mechanism 7, there are air inlet connectors 71, and the air inlet connectors 71 are connected to the gas storage cylinder 5. At the top of the air charging and discharging mechanism 7, there is a gas replenishing port 72. Inside the air charging and discharging mechanism 7, there is an air delivery chamber. On the side of the air delivery chamber, there is an automatic valve 73. The bottom of the air delivery chamber communicates with the storage space 3. The connection between the air inlet connector 71 and the gas storage cylinder 5 facilitates the gas in the gas storage cylinder 5 to enter the air delivery chamber. When gas needs to be replenished, the moving part 1 moves the loading mechanism 2 at the bottom to the gas replenishing position, and the staff inserts the gas replenishing connector into the gas replenishing port 72 at the top for gas replenishment. There is a one-way valve in the gas replenishing port 72, similar to the connector of a bicycle tire. When nitrogen needs to be replenished to the storage space 3 at the bottom, the automatic valve 73 at the bottom opens, and the nitrogen in the gas storage cylinder 5 enters the storage space 3 through the air delivery chamber. The automatic valve 73 is in a closed state when gas is replenished.

[0045] At the rear of the storage space 3, there is an air delivery compartment 31. The air delivery compartment 31 is connected to the air delivery chamber. Inside the air delivery compartment 31, air inlet holes 32 are spaced apart. The design of the air delivery compartment 31 in cooperation with the air inlet holes 32 can make nitrogen enter the storage space 3 more evenly, and the protection effect on the silicon wafers is better.

[0046] At the top of the moving part 1, there is a fixed frame 11. At the bottom of the loading mechanism 2, there is a plug-in block 12. The plug-in block 12 is detachably connected to the fixed frame 11. The fixed frame 11 and the plug-in block 12 can be connected by magnetic connection, block connection, etc., which facilitates the convenient installation and disassembly of the loading mechanism 2. The drive power supply 6 can independently supply power to the air charging and discharging mechanism 7, without relying on the power supply of the AGV cart. The loading mechanism 2 can still operate independently after being separated from the AGV cart.

[0047] The above embodiments only represent a certain implementation manner of the present invention. The description is relatively specific and detailed, but it cannot be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
