[0001] The present application relates to the technical field of LCM module feeding, in particular to a dust-free storage cabinet for automatic line LCM module feeding and wiping. BACKGROUND

[0002] Currently, in the automatic line LCM wiping feeding station, the wiped products are placed on a simple adhesive tape wrapped support for convenient transportation and storage, but dust will fall over time, and the products need to be checked and wiped again before feeding. Now, due to environmental problems, personnel are afraid to wipe too much, one is that there is no special dust-free cabinet, and two is that there is not enough space.

[0003] This process can be designed as a positive pressure dust-free storage cabinet, the products are directly placed in the shelf after wiping, which can be taken out conveniently, and it is not easy to be opened by mistake or vibration during transportation and storage, so that dust enters, and it does not matter how long it is placed, it is clean.

[0004] The above information disclosed in the background section is only used to strengthen the understanding of the background of the present disclosure, and therefore it can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0005] The purpose of the present application is to design a dust-free storage cabinet that is always in a positive pressure state, which can prevent dust from adhering to the LCM module during transportation and storage, and during the LCM module access process, to solve the above problems in the art.

[0006] In order to achieve the above purpose, the present application provides the following technical scheme: a dust-free storage cabinet for automatic line LCM module feeding and wiping, used for storing LCM modules, comprising a storage cabinet, a plurality of storage drawers are slidably installed in the storage cabinet, the storage drawers have a positive pressure gas injection channel inside, a gas injection plugging piece is fixedly installed in the storage cabinet and inserted into the positive pressure gas injection channel, the gas injection plugging piece has a gas inlet channel inside, a gas injection module is installed on the storage cabinet to inject gas into the gas inlet channel, a connecting pipe is installed on the output end of the gas injection module, and the connecting pipe and the plurality of gas injection plugging pieces are connected in parallel.

[0007] When the storage drawer is closed, the gas injection module injects gas into the positive pressure gas injection channel through the gas inlet channel to form high pressure, which increases the force required when the storage drawer is opened. When the storage drawer is opened, the gas in the positive pressure gas injection channel continuously enters the storage drawer to form positive pressure, preventing external dust from entering.

[0008] Preferably, the storage drawer includes a drawer body, a placement cavity with an upward opening at the top of the drawer body, a support block fixedly installed around the bottom surface of the placement cavity, and a clamping block fixedly installed on the top of the support block. The bottom surface of the module contacts the top surface of the support block, and the side surface of the module contacts the side wall of the clamping block.

[0009] Preferably, the positive pressure air injection channel includes a cylindrical channel opened in the drawer body, a transfer channel opened in the support block and communicating with the cylindrical channel, and an air inlet opened at the end of the cylindrical channel away from the storage cabinet.

[0010] Preferably, the air-injection sealing component includes a piston that is slidably connected within the cylindrical channel, and a connecting rod that is fixedly connected to the end of the piston. The air intake channel is opened within the connecting rod and communicates with the cylindrical channel. The connecting rod passes through the drawer body and the storage cabinet and is slidably connected to the drawer body and fixedly connected to the storage cabinet.

[0011] Preferably, the length of the piston is less than the length of the transfer channel.

[0012] Preferably, a slider is fixedly connected to the bottom of the drawer body, and a groove is provided in the storage cabinet to cooperate with the slider. When the slider is located at the end of the groove away from the connecting rod, the piston is located in the cylindrical channel to block the air inlet. When the slider is located at the end of the groove close to the connecting rod, both ends of the piston are located in the connecting channel.

[0013] Preferably, one end of the air intake channel passes through the end of the connecting rod away from the piston, and the other end of the air intake channel contacts the piston and passes through the outer wall of the connecting rod. The air intake channel is generally L-shaped.

[0014] Preferably, the gas injection module has an electronic pressure gauge for detecting the pressure value inside the connecting pipe. The gas injection module continuously injects gas into the connecting pipe until the value in the electronic pressure gauge reaches a predetermined value.

[0015] Preferably, when the piston is located in the cylindrical channel and blocks the air inlet, there is an extraction chamber between the end of the cylindrical channel away from the connecting rod and the piston.

[0016] Preferably, a handle is fixedly installed on the drawer body.

[0017] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0018] 1. This invention, through the cooperation between the storage drawer, the positive pressure gas injection channel, the gas injection sealing component and the existing gas injection module, enables the gas injection module to continuously inject gas into the storage drawer through the positive pressure gas injection channel to form a positive pressure space when the storage drawer is opened in the storage cabinet, and continuously exhaust the outside air to prevent external dust from entering the storage drawer with the air and contaminating the wiped LCM module. Therefore, there is no need to check and wipe again before loading, shortening the process.

[0019] 2. This invention, through the cooperation between the storage drawer, the positive pressure gas injection channel, the gas injection sealing component, and the existing gas injection module, enables the gas injection module to inject gas into the positive pressure gas injection channel to form positive pressure when the storage drawer is closed in the storage cabinet. This requires the gas in the positive pressure gas injection channel to be compressed when the storage drawer is opened, thereby creating resistance to opening the drawer body. This prevents the drawer body from opening due to vibration or accidental contact during storage and transportation, thus preventing external dust from contaminating the stored LCM module.

[0020] 3. At the same time, the present invention has a simple structure and has two states when the storage drawer is open and closed, but both are guaranteed to be in a positive pressure state, thereby preventing the stored LCM module from being contaminated by external dust, so that personnel need to check and wipe it again before loading.

[0033] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0035] This invention provides, for example Figures 1-9The diagram shows a cleanroom storage cabinet for wiping and loading LCM modules on an automated production line. The cabinet, used to store LCM modules 1, includes a storage cabinet 2. Multiple storage drawers 3 are slidably installed from top to bottom inside the storage cabinet 2. Each drawer 3 includes a drawer body 301, with a handle 13 fixedly mounted on it. The top of the drawer body 301 has an upward-opening placement cavity 302. Multiple support blocks 303 are fixedly mounted around the bottom surface of the placement cavity 302. Each support block 303 has a clamping block 304 fixedly mounted on its top, contacting the side wall of the placement cavity 302. Simultaneously, a clamping block 304 is fixedly mounted on the bottom of the drawer body 301. The storage cabinet 2 has a sliding groove 10 that is slidably connected to the slider 9. When the module 1 is placed into the placement cavity 302, the bottom surface of the module 1 contacts the top surface of the support block 303, and a bottom cavity is formed between the bottom surface of the module 1 and the bottom of the placement cavity 302. The side of the module 1 is fixedly connected to the side wall of the clamping block 304. This bottom cavity is connected to the outside through the ventilation gap between the module 1, the placement cavity 302 and the clamping block 304. When gas is injected into this bottom cavity, the gas will be discharged to the top of the drawer body 301 through the ventilation gap, filling the placement cavity 302 to form a positive pressure space with a pressure greater than that of the outside.

[0036] The drawer body 301 has a positive pressure air injection channel 4 inside. The positive pressure air injection channel 4 includes a cylindrical channel 401 opened in the side of the drawer body 301. A transfer channel 402 is also opened in the clamping block 304 and the support block 303. The transfer channel 402 is connected to the cylindrical channel 401 and is larger than the cylindrical channel 401. An air inlet 403 communicating with the bottom cavity is opened at the end of the cylindrical channel 401 away from the storage cabinet 2. A piston 501 with a length shorter than the transfer channel 402 is slidably installed in the cylindrical channel 401. A connecting rod 502 is fixedly installed at one end of the 01. The connecting rod 502 passes through the drawer body 301 and the storage cabinet 2, and is slidably connected to the drawer body 301 and fixedly connected to the storage cabinet 2. An L-shaped air intake channel 6 is opened inside the connecting rod 502. One end of the air intake channel 6 passes through the end of the connecting rod 502 away from the piston 501, and the other end contacts the piston 501 and passes laterally through the outer wall of the connecting rod 502. The piston 501 and the connecting rod 502 constitute the air injection sealing component 5. When gas is injected from the end of the connecting rod 502 away from the piston 501, it will... The air enters the cylindrical channel 401 near the connecting rod 502 through the intake channel 6. If the drawer is closed, the slider 9 will be located at one end of the slide groove 10, while the piston 501 will be located at the end of the cylindrical channel 401 away from the connecting rod 502. The piston 501 will block the intake port 403. There is a separation chamber between the end of the cylindrical channel 401 away from the connecting rod 502 and the piston 501. The piston 501 is not completely in contact with the end of the cylindrical channel 401, so the gas cannot enter the bottom cavity through the cylindrical channel 401 and the intake port 403. This will cause the pressure in the cylindrical channel 401 away from the handle 13 to gradually increase. When the handle 13 is used to pull the drawer body 301 to open, the side of the drawer body 301 away from the handle 13 will gradually approach the piston 501. This requires compressing the gas in the cylindrical channel 401 which is already under positive pressure, thereby creating resistance to pull the drawer body 301 open. This can prevent the drawer body 301 from opening during transportation or misoperation, causing dust to enter the placement cavity 302 and contaminate the LCM template.

[0037] When the operator pulls handle 13 to overcome resistance and slider 9 slides to the other end of groove 10, piston 501 will move into the connecting channel, at which point the gas under positive pressure will... Figure 6 As shown, the gas enters the bottom cavity through the columnar channel 401, the connecting channel, and then through the air inlet 403, so that the placement cavity 302 of the drawer body 301 is in a positive pressure state, and the gas is continuously discharged outward. In this way, when the storage drawer 3 is opened, the storage drawer 3 can be in a positive pressure state, preventing external dust from entering the placement cavity 302 and contaminating the LCM template when storing or retrieving the template.

[0038] Here, an existing gas injection module 7 is fixedly installed on the storage cabinet 2. A connecting pipe 8 is fixedly installed on the output end of the gas injection module 7, and multiple connecting rods 502 are connected in parallel with the connecting pipe 8. This gas injection module 7 has an electronic pressure gauge 11 that can detect the pressure value inside the connecting pipe 8. As long as the value of the electronic pressure gauge 11 does not exceed the set value, the gas injection module 7 will continuously inject gas into the connecting pipe 8 to ensure that the cylindrical channel 401 is in a positive pressure state.

[0039] In actual operation, the worker pulls handle 13 to overcome resistance and open the drawer body 301. Figure 7 As shown, the electronic pressure gauge 11 detects that the pressure value does not exceed the set value. The air injection module 7 continuously injects gas into the cylindrical channel 401, so that the placement cavity 302 in the drawer body 301 is in a positive pressure state, making it difficult for external dust to enter. Then, the staff puts the wiped LCM template into the placement cavity 302, which contacts the support block 303 and the clamping block 304. After that, the staff pushes the drawer body 301 back into the storage cabinet 2. At this time, the piston 501 blocks the air inlet 403, and the air pressure in the cylindrical channel 401 and the connecting pipe 8 gradually increases to the set value. The air injection module 7 stops injecting gas. At this time, the air pressure in the part of the cylindrical channel 401 connected to the connecting channel is greater than the air pressure in the extraction chamber 12, forming a resistance that prevents the drawer body 301 from opening out of the storage cabinet 2.

[0040] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
