Description

Technical Field

[0001] The utility model relates to the technical field of printed circuit board processing equipment, in particular to a soaking transmission device of a blow dryer. Background Art

[0002] During the wet process of printed circuit boards, drying equipment is usually used to perform cold air drying and hot air drying on the PCB surface in sequence. However, due to long-term use, a large amount of dust will accumulate in the internal cavity of the drying equipment, and the conveying rollers will be greasy or dusty, which is not easy to clean manually.

[0003] The Chinese utility model patent application disclosure CN213017629U discloses an immersion-type gear transmission dust-proof structure. Although the immersion-type gear transmission dust-proof structure solves the problem of dust generated by the friction of the conveying wheel group during transmission in the existing drying equipment, when the transmission components in the immersion transmission device of the dryer are continuously flushed by liquid, the flushed dust is easily deposited under the transmission components or attached to the inner wall of the immersion tank, becoming thicker and thicker, so it needs to be cleaned. The transmission components are installed in the immersion tank, which makes it inconvenient to clean the dust attached to the inner wall of the immersion tank, reducing the cleaning efficiency of the immersion tank. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the transmission components in the existing blow dryer immersion transmission device are continuously flushed by liquid, and the dust flushed is easily deposited under the transmission components or adheres to the inner wall of the immersion tank, becoming thicker and thicker, so it needs to be cleaned. The transmission components are installed in the immersion tank, which makes it inconvenient to clean the dust adhered to the inner wall of the immersion tank, thereby reducing the cleaning efficiency of the immersion tank. A blow dryer immersion transmission device is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A immersion transmission device for a hair dryer includes a body, a conveying assembly, and a immersion tank installed on the body. The immersion tank includes an outer frame and a liquid-carrying bottom box installed inside the outer frame. The outer frame is provided with a mounting groove, and a lifting member is installed on the mounting groove for driving the liquid-carrying bottom box to move up and down. A connecting plate is provided between the lifting member and the liquid-carrying bottom box.

[0007] The lifting part drives the liquid-carrying bottom box to move downward from the outer frame to complete the separation action, thereby facilitating the cleaning component to clean the dust and dirt inside the liquid-carrying bottom box, and facilitating the staff to repair or replace the components in the transmission component. The structure is simple in design, easy to use, and has high cleaning efficiency. The operator starts the electrical switches on the device on the PLC controller to perform automatic cleaning operations on the immersion tank, which has high practicality and does not require manual cleaning of the immersion tank, saving human resources.

[0008] Furthermore, the liquid carrying bottom box includes short side panels, long side panels and a bottom plate, and the short side panels and the long side panels are respectively provided with two groups, and the two groups of short side panels and one group of long side panels are provided with U-shaped grooves, and a cover plate is provided on the outer frame, and the transmission structure is dust-flushed in the liquid carrying bottom box by liquid. When it is necessary to clean the adhered dust and dirt, the outer frame is separated from the liquid carrying bottom box, making cleaning more convenient. When the liquid carrying bottom box is combined with the outer frame, the U-shaped grooves on the liquid carrying bottom box correspond to the various rotating shaft positions on the outer frame, completing the installation work between the liquid carrying bottom box and the outer frame.

[0009] Furthermore, a drain outlet is provided at the bottom of the base plate, and a water inlet pipe is provided on the cover plate.

[0010] Furthermore, a cleaning assembly is installed on the bottom plate, and the cleaning assembly includes a cleaning plate and a screw module. The cleaning plate is provided with tiny cleaning strips and scrapers for driving the two groups of cleaning plates to move toward the middle of the liquid-carrying bottom box to clean the dust and dirt on the inner wall. The tiny cleaning strips and scrapers on the outside of the cleaning plate abut against the inner wall of the liquid-carrying bottom box to clean the dust and dirt.

[0011] Furthermore, a transmission assembly is provided in the soaking tank, and the transmission assembly includes a transmission wheel, a transmission belt and a transmission shaft. A driving member is installed outside the outer frame, and the transmission wheels are distributed in two groups.

[0012] Furthermore, the body includes a first air filter, a second air filter, a high-pressure blower, a heating box assembly and a conveying assembly that is arranged through the body. The upper and lower parts of the conveying assembly are equipped with blowing knives and air ducts for communication. The blowing knives are divided into cold air treatment areas and hot air treatment areas.

[0013] Furthermore, the conveying assembly includes a rotating rod, a wheel and a rotating shaft installed on the outer frame. The other end of the rotating shaft passes through the body and is connected to the rotating rod. A sealing member is provided on the rotating shaft.

[0014] Furthermore, a water level sensor is installed inside the liquid carrying bottom box to monitor the position of the liquid inside the liquid carrying bottom box.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] The utility model discloses that the liquid-carrying bottom box is driven by the lifting member to move downward from the outer frame to separate from it, thereby facilitating the cleaning component to clean the internal dust and dirt of the liquid-carrying bottom box, so that the dust and dirt will not accumulate in the immersion tank and affect the subsequent dust flushing operation of the transmission structure by the liquid. In addition, the structure is convenient for the staff to repair or replace the components in the transmission assembly, is easy to use, has high cleaning efficiency and strong practicality, and does not require manual cleaning of the immersion tank, thereby saving human resources.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-4 A soaking transmission device for a hair dryer includes a body 1, a conveying assembly 5 and a soaking tank 4 installed on the body 1. The soaking tank 4 includes an outer frame 20 and a liquid-carrying bottom box 12 installed inside the outer frame 20. A mounting groove 14 is opened on the outer frame 20. A lifting member 1401 is installed on the mounting groove 14 for driving the liquid-carrying bottom box 12 to move up and down. A connecting plate 19 is provided between the lifting member 1401 and the liquid-carrying bottom box 12.

[0025] The lifting member 1401 includes a hydraulic rod and a mounting frame, and the mounting frame is installed in the mounting groove 14 in a U-shaped structure so that it will not interfere with the transmission operation of the transmission component 3. When the liquid-carrying bottom box 12 needs to be cleaned, the liquid in the liquid-carrying bottom box 12 is drained through the drain port 17, and then the lifting member 1401 drives the liquid-carrying bottom box 12 to move downward from the outer frame 20 and separate from it, thereby facilitating the cleaning component 22 to clean the internal dust and dirt of the liquid-carrying bottom box 12, and facilitating the staff to repair or replace the components in the transmission component 3. The present structure is simple in design, easy to use, and has high cleaning efficiency. The operator starts the various electrical switches on the device on the PLC controller to perform automatic cleaning operations on the immersion tank 4, which has high practicality and does not require manual cleaning of the immersion tank 4, saving human resources.

[0026] The liquid carrying bottom box 12 includes short side panels 1201, long side panels 1202 and a bottom panel 1203. The short side panels 1201 and the long side panels 1202 are respectively provided in two groups, and U-shaped grooves 13 are provided on the two groups of short side panels 1201 and one group of long side panels 1202. A cover panel 21 is provided on the outer frame 20.

[0027] The cover plate 21 is installed with the outer frame 20, and the contact surface between the bottom of the cover plate 21 and the top of the outer frame 20 is provided with a limit block and a limit groove, which is used to fix the cover plate 21 to prevent the cover plate 21 and the outer frame 20 from being misaligned during equipment operation. The shape of the liquid-carrying bottom box 12 is consistent with the shape of the outer frame 20, so that it forms a detachable box-like part, which facilitates the dust flushing operation of the transmission structure by liquid. When it is necessary to clean the settled dust and dirt, the cleaning is more convenient by separating the liquid-carrying bottom box 12. When the liquid-carrying bottom box 12 is combined with the outer frame 20, the U-shaped groove 13 on the liquid-carrying bottom box 12 corresponds to the positions of the rotating shafts 503 on the outer frame 20, completing the installation work between the liquid-carrying bottom box 12 and the outer frame 20.

[0028] A drain outlet 17 is provided at the bottom of the base plate 1203 , and a water inlet pipe is provided on the cover plate 21 .

[0029] The drain outlet 17 and the water inlet pipe are both connected to an external water source and a water circulation system (the system is prior art and will not be described in detail here) to complete the water circulation and flushing work.

[0030] A cleaning assembly 22 is installed on the bottom plate 1203. The cleaning assembly 22 includes a cleaning plate 2201 and a screw module 2202. The cleaning plate 2201 is provided with tiny cleaning strips and scrapers.

[0031] The screw module 2202 includes a micro motor and a bidirectional screw connected to the output end of the micro motor. A slide connected to the cleaning plate 2201 is mounted on the bidirectional screw. The slide has a threaded hole that cooperates with the bidirectional screw and is used to drive the two sets of cleaning plates 2201 to move toward the middle of the liquid-carrying bottom box 12 to clean the dust on the inner wall. The small cleaning strips and scrapers on the outside of the cleaning plates 2201 abut against the inner wall of the liquid-carrying bottom box 12 to clean the dust.

[0032] Specifically, the cleaning component 22 is arranged at the upper edge of the liquid-carrying bottom box 12 to avoid leakage caused by being arranged at the bottom or side of the liquid-carrying bottom box 12. When the cleaning operation is not performed, the cleaning plates 2201 of the cleaning component 22 are located at both ends of the liquid-carrying bottom box 12 so that it will not interfere with the operation of the transmission component 3, and has high practicality.

[0033] A transmission assembly 3 is provided in the soaking tank 4. The transmission assembly 3 includes a transmission wheel 301, a transmission belt 302 and a transmission shaft 303. A driving member 2 is installed outside the outer frame 20. There are two groups of transmission wheels 301.

[0034] One of the two sets of transmission wheels 301 is driven by spur gears, and the other is driven by bevel gears. The transmission belt 302 is arranged on the spur gears; the driving member 2 adopts a servo motor, which drives the spur gear transmission through the servo motor, drives the transmission shaft 303 to rotate, and makes the other set of bevel gears rotate, and finally drives the conveying component 5 to roll to carry out the workpiece conveying operation.

[0035] The body 1 includes a first air filter 6, a second air filter 9, a high-pressure blower 8, a heating box assembly 10 and a conveying assembly 5 that is arranged through the body 1. The upper and lower parts of the conveying assembly 5 are equipped with a blowing knife 11 and an air duct 7 for communication. The blowing knife 11 is divided into a cold air treatment area and a hot air treatment area.

[0036] The blowing knife 11 in the cold air treatment area is connected to the second air filter 9, the high-pressure blower 8 and the first air filter 6 through the air duct 7 in sequence, so that the air is first sucked in from the first air filter 6, enters the high-pressure blower 8 through the air duct 7, and after high-pressure compression, enters the second air filter 9 and the blowing knife 11 from the air duct 7, and blows to the surface of the circuit board, and the cycle is repeated; the blowing knife 11 in the hot air treatment area sucks in gas through the high-pressure blower 8 in turn, and the suction port is located in the body 1 and is connected to the high-pressure blower 8 through the air duct 7. After high-pressure compression, the air enters the heating box assembly 10 through the air duct 7 to a preset temperature, and then enters the second air filter 9 and the blowing knife 11 in the hot air treatment area through the air duct 7 and is blown to the surface of the circuit board.

[0037] The conveying assembly 5 includes a rotating rod 502 , a wheel 501 and a rotating shaft 503 mounted on the outer frame 20 . The other end of the rotating shaft 503 passes through the body 1 and is connected to the rotating rod 502 . A sealing member 15 is provided on the rotating shaft 503 .

[0038] The seal 15 is connected to the inner wall of the outer frame 20, so that the rotary seal 15 is fixed on the rotating shaft 503, so that the sealing effect is better. After the conveying component 5 is driven by the transmission component 3, the wheel 501 rotates to convey the workpiece.

[0039] A water level sensor 16 is installed inside the liquid carrying bottom box 12 for monitoring the position of the liquid inside the liquid carrying bottom box 12 .

[0040] Monitor whether the water level exceeds the set threshold. When it exceeds the set threshold, send a signal to the PLC controller to remind the staff to check and handle it to avoid liquid overflow and spread to the equipment of the body 1, thereby affecting the use status of the body 1. The structures not introduced in the present invention do not involve the design points and improvement directions of the present invention. They are the same as the existing technology or can be implemented by using the existing technology and are not described here. This application does not limit the specifications of the water level sensor 16.

[0041] Working principle: connect the power cord of the machine body 1, and control the switches of various electrical components on the device through the PLC controller. When the dryer is drying the circuit board, the water pipe of the water source equipment is connected through the water inlet on the cover plate 21, and the liquid is injected into the soaking tank 4 to perform dust flushing on the transmission structure. When the equipment needs to be cleaned from the dust and dirt deposited in the soaking tank 4 after a long period of use, the lifting member 1401 drives the liquid-carrying bottom box 12 to move downward from the outer frame 20, completing the disassembly operation of the soaking tank 4, and then facilitating the cleaning of the internal dust and dirt of the liquid-carrying bottom box 12 through the cleaning component 22, and also facilitating the staff to repair or replace the components in the transmission component 3. The structure is simple in design, easy to use, and has high cleaning efficiency. It has high practicality and does not require manual cleaning of the dust and dirt in the soaking tank 4, saving human resources.
