When the fan is working, the air inside the filter cavity is extracted and a negative pressure state is formed. Since a negative pressure state is formed inside the filter cavity, the air filter located on the open mouth will absorb and filter the glue mist, dust and other dust generated by the workpiece during the glue spraying operation in real time, and draw them into the filter cavity and then extract them out, so as to ensure that the workpiece can achieve green glue spraying operation and reduce the harm of glue mist, dust and other dust to the health of on-site personnel and the pollution to the air.

[0016] 2. The air extracted from the filter chamber does not contain any glue mist, dust or other dust, and is effectively purified. It can be discharged back to the glue spraying operation site to reuse the filtered air and achieve the purpose of energy saving and environmental protection.

[0017] 3. A continuous air path is formed between the open opening, the receiving opening, the connecting opening, the filtering through hole of the receiving part, the branch flow hole, the air outlet, the connecting pipe, and the exhaust port. With the use of the fan, the air flow entering the filter cavity forms a one-way flow, which not only helps the glue spraying work, so that the glue and paint can only be sprayed in the direction of the workpiece, thereby improving the production efficiency and the glue spraying quality, but also ensures that the air filter can effectively adsorb and filter the glue mist, dust and other dust, ensuring that the glue spraying operation site has a good working environment.

[0018] 4. When the fan is working, it can make the filter cavity form a sealed and negative pressure cavity, thereby forming a slightly positive pressure on the glue and paint sprayed by the robot, and spraying the workpiece, thereby improving the utilization rate of glue and paint and reducing the scrap rate of the workpiece; in addition, the airflow around the workpiece can only be filtered through the air filter cavity, so it can prevent the glue spraying airflow from running around, ensuring that the glue spraying environment will not be polluted by the glue spraying airflow, and at the same time it can also improve the quality of the finished glue spraying products.

[0019] 5. Use the filter diversion chamber to divert and limit the speed of glue mist, dust and other dusts before entering the filter chamber, so that the flow rate of glue mist, dust and other dusts at the glue spraying operation site is uniform and effectively filtered and purified, so as to reduce the high production cost problem caused by the need to add a purification system at the glue spraying operation site. At the same time, the diversion and speed limit of glue mist, dust and other dusts can also reduce the noise during air filtration and purification, so as to ensure a good working environment at the glue spraying operation site.

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Refer to Figures 1 - 7 , the air filtration structure of the present glue spraying production line includes a machine tool 1, a conveying mechanism, and a manipulator 2. The conveying mechanism includes a conveying bracket, a driving assembly, and a material receiving unit 3. The conveying bracket is fixedly arranged on the machine tool 1. A workpiece 4 is placed on the material receiving unit 3 and moves along the direction set by the conveying bracket under the drive of the driving assembly. The manipulator 2 is arranged outside the machine tool 1 and / or the material receiving unit 3 and performs glue spraying operations on the workpiece 4. An air filtration member (not shown in the figure) is detachably installed on the machine tool 1 and / or the conveying bracket. When assembled, the air filtration member is located below and / or outside the workpiece 4. A filtration cavity 5 is formed inside the machine tool 1 through the air filtration member. An air outlet 6 is further arranged on the machine tool 1, and a fan (not shown in the figure) for extracting the air inside the filtration cavity 5 is connected through the air outlet 6.

[0029] The air filtration member in this embodiment can be filter cotton or a filter net, etc., and can be removed and cleaned for repeated use. In order to improve the filtration effect and reduce the filtration cost at the same time, the air filtration member in this embodiment preferably uses filter cotton.

[0030] The top of the machine tool 1 is open and forms an open opening 7. A support frame 8 is horizontally arranged on the open opening 7. The conveying bracket is fixedly arranged on the support frame 8. A machine tool support member 9 is further arranged on the support frame 8. The air filtration member is detachably installed on the machine tool support member 9.

[0031] The machine tool carrier 9 is disc-shaped, with a placement opening 10 provided at its top, a communication opening 11 provided at its bottom, and a placement portion 12 provided on its inner sidewall; the machine tool carrier 9 communicates with the open opening 7 of the machine tool 1 through the communication opening 11; the air filter element is longitudinally disassembled and assembled on the placement portion 12 through the placement opening 10 and is located outside the workpiece 4 during assembly.

[0032] The disc-shaped machine tool carrier 9 can effectively position the air filter element to reduce the problem that the displacement of the air filter element caused by air flow affects the filtering effect of dust such as glue mist and dust. At the same time, the filter cotton is disassembled and assembled longitudinally, which is convenient, fast, and has a simple structure.

[0033] The air outlet 6 is provided on the sidewall of the machine tool 1, and a communication pipe 13 is provided thereon, and an exhaust port 14 is provided on the communication pipe 13; the fan is communicated with the exhaust port 14. Among them, when the fan is working, the dust generated during the glue spraying operation of the workpiece 4 is filtered through the air filter element into the filter cavity 5, and then the air inside the filter cavity 5 is sequentially extracted through the air outlet 6, the communication pipe 13, and the exhaust port 14.

[0034] The fan in this embodiment can be a variable-frequency fan, which can achieve variable-frequency adjustment, and the air volume can be adaptively adjusted according to the actual use environment (such as the concentration of dust such as glue mist and dust, or the glue spraying operation speed of the manipulator 2, etc.), so as to improve the smooth control ability of the air speed during air filtration. At the same time, the communication pipe 13 has a centralized effect on the filtered air, enabling the air inside the filter cavity 5 to be extracted only in one position, ensuring the air flow efficiency.

[0035] In order to reduce the floor space of the glue spraying production line, the manipulator 2 is arranged on the same side as the communication pipe 13.

[0036] The above-mentioned conveying bracket includes left and right side plates 15, the left and right side plates 15 are respectively fixedly arranged on the support frame 8 along the direction in which the machine tool 1 is arranged, a fixed cross bar 16 is arranged between the left and right side plates 15, and a bracket placement member 17 is arranged through the fixed cross bar 16; the air filter element is disassembled and assembled on the bracket placement member 17.

[0037] The bracket placement member 17 in this embodiment is plate-shaped and is provided with a plurality of placement member filter through holes 18 thereon; side openings 19 are respectively provided on the left and right side plates 15; the air filter element is laterally disassembled and assembled on the bracket placement member 17 through the side openings 19.

[0038] Using the plate-mounted bracket placement member 17 to place the air filter element can ensure that the air filter element can be effectively positioned to reduce the problem that the displacement of the air filter element caused by air flow affects the filtering effect of dust such as glue mist and dust. At the same time, the filter cotton is disassembled and assembled laterally, which is convenient, fast, and has a simple structure.

[0039] The driving assembly includes a rotating cross bar 20, a sprocket 21, a revolving chain 22, a driving motor 23 and a speed reducer 24; there are two rotating cross bars 20, which are respectively rotatably arranged at the front and rear ends of the left and right side plates 15; there are four sprockets 21, which are respectively arranged in transmission connection with the front and rear rotating cross bars 20; there are two left and right revolving chains 22, and the left and right revolving chains 22 are respectively wound around the sprockets 21 at the front and rear ends; the driving motor 23 and the speed reducer 24 are respectively fixedly arranged on the conveying bracket or the machine tool 1, and the two are in driving connection; one of the sprockets 21 is in driving connection with the speed reducer 24; the material receiving unit 3 is paved between the left and right revolving chains 22, and rotates between the left and right side plates 15 through the cooperation of the rotating cross bar 20, the sprocket 21, the revolving chain 22, the driving motor 23 and the speed reducer 24.

[0040] The above-mentioned material receiving unit 3 is completely paved between the left and right revolving chains 22. For the convenience of viewing the assembly of the bracket bearing member 17, only a partial schematic paving of the material receiving unit 3 is shown between the left and right revolving chains 22 in the drawings.

[0041] The revolving chain 22 forms a longitudinal revolving spacing through the winding of the sprocket 21; the side opening 19 and the bracket bearing member 17 are respectively located between the longitudinal revolving spacings; the air filter element is laterally disassembled and assembled on the bracket bearing member 17 through the side opening 19, and is located below the workpiece 4 and between the longitudinal revolving spacings during assembly.

[0042] When the fan is working, it extracts the air inside the filtering cavity 5 and makes it in a negative pressure state. Since a negative pressure state is formed inside the filtering cavity 5, the air filter element located on the open opening 7 will adsorb and filter the glue mist, dust and other dust generated by the workpiece 4 during the glue spraying operation in real time, and suck it into the filtering cavity 5 and then extract it, so as to ensure that the workpiece 4 can realize green glue spraying operation and reduce the harm to the health of on-site personnel and the pollution of the air caused by glue mist, dust and other dust.

[0043] Among them, the air flow filtering direction of the glue mist, dust and other dust is as Figure 2 shown by the arrow.

[0044] The air extracted from the filtering cavity 5 has no glue mist, dust and other dust, and is effectively purified, and can be re-discharged to the glue spraying operation site to reuse the filtered air, so as to achieve the purpose of energy conservation and environmental protection.

[0045] When the fan is working, it can make the filter cavity 5 form a sealed and negative pressure cavity, thereby forming a slightly positive pressure on the glue and paint sprayed by the robot 4, and performing glue spraying on the workpiece 4, thereby improving the utilization rate of glue and paint and reducing the scrap rate of the workpiece 4; in addition, the airflow around the workpiece 4 can only be filtered through the air filter cavity 5, so it can prevent the glue spraying airflow from running around, ensuring that the glue spraying environment will not be polluted by the glue spraying airflow, and at the same time it can also improve the quality of the glue spraying product.

[0046] The support frame 8 is also provided with an air diverter plate 25, and a plurality of air diverter plates 25 are provided and are respectively paved in the middle of the support frame 8 along the direction in which the machine tool 1 is set, and a plurality of diverter holes 26 are respectively provided on the air diverter plates 25, and the plurality of diverter holes 26 are connected with the filter cavity 5 through the open port 7. The air diverter plate 25 is completely paved in the middle of the support frame 8, thereby opening the left and right sides of the machine tool 1, which is convenient for assembling the machine tool receiving part 9.

[0047] There are several machine tool receiving parts 9, which are fixed on the left and right sides of the support frame 8 along the direction in which the air diverter plate 25 is set, and are connected with the filter cavity 5 through the open port 7; the conveying bracket is located above the air diverter plate 25; a filter diverter cavity 27 is formed between the bracket receiving part 17 and the air diverter plate 25, and the filter diverter cavity 27 is connected with the filter cavity 5 through the diversion hole 26 and the open port 7.

With the use of the fan, the air flow entering the filter cavity 5 forms a one-way flow, which not only helps the glue spraying work, so that the glue and paint can only be sprayed in the direction of the workpiece 4, thereby improving the production efficiency and glue spraying quality, but also ensures that the air filter can effectively adsorb and filter the glue mist, dust and other dust, ensuring that the glue spraying operation site has a good working environment.

[0049] The filter diversion chamber 27 is used to divert and limit the speed of glue mist, dust and other dusts before entering the filter chamber 5, so that the flow rate of glue mist, dust and other dusts at the glue spraying operation site is uniform and effectively filtered and purified, so as to reduce the high production cost problem caused by the need to add a purification system at the glue spraying operation site. At the same time, the diversion and speed limiting of glue mist, dust and other dusts can also reduce the noise during air filtration and purification, so as to ensure that the glue spraying operation site has a good working environment.
