Description

Technical Field

[0001] This utility model belongs to the field of paint mist recovery, and specifically relates to a paint mist recovery structure for an automotive painting robot. Background Technology

[0002] A paint mist recovery device is a piece of equipment used to treat paint mist particles generated during spray painting operations. Its main function is to capture and centrally process paint mist particles suspended in the air through physical or chemical methods to reduce environmental pollution and improve workplace safety. During the spraying process, paint is atomized under high pressure to form tiny particles. These particles not only pollute the air but may also harm the health of operators and cause paint waste. However, single-stage paint mist recovery devices, which only use single-stage treatment technology such as a single filter or water curtain system, have obvious drawbacks, even though they are simple in structure and low in cost. First, the recovery efficiency of single-stage devices is low, especially in terms of the ability to capture fine paint mist particles. This is because the pore size or adsorption capacity of a single filter medium is limited and cannot effectively intercept particles of all sizes, causing some paint mist to escape into the environment. Therefore, we hope to design a paint mist recovery structure for automotive painting robots to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a paint mist recovery structure for an automotive painting robot, thereby solving the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a paint mist recovery structure for an automotive painting robot, comprising: a recovery box, wherein a graded recovery mechanism is provided inside the recovery box, and a collection mechanism for temporarily storing and recovering paint mist is provided at the lower end of the recovery box;

[0005] The graded recycling mechanism includes a primary recycling chamber located at the left end of the recycling box, a secondary recycling chamber located inside the right end of the recycling box, and a vortex assembly located at the left end of the recycling box.

[0006] The graded recycling mechanism also includes a connecting plate. A positive and negative electrode plate is located at the lower end of the connecting plate, and a connecting rod is fixedly connected to the upper end of the connecting plate. The connecting rod slides through the upper end of the recycling box, and a mounting plate is fixedly connected to the upper end of the connecting rod. The lower surface of the mounting plate is elastically connected to the recycling box via a spring. A vibration motor is installed on the mounting plate. By setting up the graded recycling mechanism, large paint mist particles can be quickly processed through cyclone centrifugal separation, reducing the load on subsequent processing. Then, fine paint mist particles are effectively captured through electrostatic adsorption to adapt to paint mist of different particle sizes, thereby improving the overall recycling efficiency.

[0007] In a preferred embodiment, the swirl assembly includes swirl fan blades and a support frame. The support frame is fixedly connected to the inside of the left end of the recycling bin. The fixed shaft at the rear end of the swirl fan blades is connected to the support frame via a bearing. By setting the swirl assembly, air is forced to move tangentially along the blades to form a rotating airflow, thereby causing the air to generate centrifugal force in the radial direction.

[0008] In a preferred embodiment, the walls of the primary recovery chamber are coated with a polytetrafluoroethylene coating that makes it difficult for paint mist to adhere and has excellent chemical resistance.

[0009] In a preferred embodiment, a negative pressure fan for creating negative pressure inside the recycling bin is provided at the right end.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. By setting up a graded recycling mechanism, large paint mist particles can be quickly processed through cyclone centrifugation, reducing the load on subsequent processing.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 As the first embodiment of this utility model:

[0029] A paint mist recovery structure for an automotive painting robot includes: a recovery box 1, a graded recovery mechanism 2 inside the recovery box 1, and a collection mechanism 3 for temporarily storing and recovering paint mist at the lower end of the recovery box 1.

[0030] The graded recycling mechanism includes a primary recycling chamber 22, which is located at the left end of the recycling box 1. A secondary recycling chamber 23 is located inside the right end of the recycling box 1. A vortex assembly 21 is also provided at the left end of the recycling box 1.

[0031] The graded recycling mechanism also includes a connecting plate 24. The lower end of the connecting plate 24 is provided with positive and negative electrode plates 25, and the upper end of the connecting plate 24 is fixedly connected with a connecting rod 26. The connecting rod 26 slides through the upper end of the recycling box 1, and the upper end of the connecting rod 26 is fixedly connected with a mounting plate 27. The lower surface of the mounting plate 27 is elastically connected to the recycling box 1 by a spring 28. A vibration motor 29 is provided on the mounting plate 27. By setting up the graded recycling mechanism 2, large paint mist particles can be quickly processed by cyclone centrifugal separation, reducing the subsequent processing load. Then, fine paint mist particles are effectively captured by electrostatic adsorption to adapt to paint mist of different particle sizes, thereby improving the overall recycling efficiency.

[0032] The swirl assembly 21 includes a swirl fan blade 211 and a support frame 212. The support frame 212 is fixedly connected to the inside of the left end of the recycling box 1. The fixed shaft at the rear end of the swirl fan blade 211 is connected to the support frame 212 through a bearing. By setting the swirl assembly 21, air is forced to move tangentially along the blade to form a rotating airflow, which in turn causes the air to generate centrifugal force in the radial direction.

[0033] The walls of the primary recovery chamber 22 are coated with a polytetrafluoroethylene coating that makes it difficult for paint mist to adhere and has excellent chemical resistance.

[0034] A negative pressure fan is installed at the right end of the recycling bin 1 to create negative pressure inside it.

[0035] Specifically, when paint mist needs to be recovered, the negative pressure fan is first started. The negative pressure fan creates a pressure difference between the inside of the recovery box 1 and the outside, causing the air to carry the paint mist rapidly towards the primary recovery chamber 22 of the recovery box 1. At the same time, the rapidly flowing air moves tangentially along the blades, forming a rotating airflow, which in turn generates centrifugal force in the radial direction. Large paint droplets collide with the cylinder wall under the action of centrifugal force. Under the action of the polytetrafluoroethylene coating, the paint mist is difficult to adhere to the cavity wall of the primary recovery chamber 22. Finally, it is collected by the bottom collection mechanism 3. Further, the paint mist recovered by the primary recovery chamber 22 then enters the interior of the secondary recovery chamber 23 for secondary recovery. The front cross-section of the secondary recovery chamber 23 and the primary recovery chamber 22 is trapezoidal, and the secondary recovery chamber 23 is wider than the primary recovery chamber 22. This reduces the flow velocity of the airflow after it enters the secondary recovery chamber 23, prolonging the residence time of the airflow. Then, based on the Coulomb force and dielectric force generated by the positive and negative electrode plates 25, smaller paint mists are captured a second time to adapt to paint mists of different particle sizes, thereby improving the overall recovery efficiency. Finally, the vibration motor 29 can be started, which drives the mounting plate 27, the connecting rod 26, and the connecting plate 24 to vibrate. The connecting plate 24 then drives the positive and negative electrode plates 25 to vibrate, shaking off the paint mist attached to their surfaces into the collection mechanism 3, thus completing the collection of paint mist.

[0036] Please see Figure 1 as well as Figure 6 As a second embodiment of this utility model:

[0037] The collection mechanism 3 includes a collection hopper 31, which is fixedly connected to the lower left side of the recycling bin 1. A connecting pipe 32 is fixedly connected to the lower end of the collection hopper 31, and the other end of the connecting pipe 32 is fixedly connected to the collection bin 33. By setting up the collection mechanism 3, the graded paint mist is collected into the collection bin 33 using the collection hopper 35 and the collection pipe 36, which facilitates unified cleaning and recycling.

[0038] A support foot 34 is fixedly connected to the lower surface of the collection hopper 31, and the lower end of the support foot 34 is fixedly connected to the collection box 33.

[0039] The collection mechanism 3 also includes a second collection hopper 35, which is fixedly connected to the lower right side of the recycling box 1. A collection pipe 36 is fixedly connected to the lower end of the second collection hopper 35, and the other end of the collection pipe 36 is fixedly connected to the collection box 33.

[0040] The front cross-section of both collecting bucket 31 and collecting bucket 35 is a trapezoidal structure that is wider at the top and narrower at the bottom.

[0041] Based on the above embodiments, the larger paint mist particles after being impacted by centrifugal force into the cylinder wall flow into the interior of the first collection hopper 31 under the action of the polytetrafluoroethylene coating, and then flow into the interior of the collection box 33 through the connecting pipe 32. At the same time, the paint mist that has been shaken off will flow into the interior of the collecting pipe 36 through the second collection hopper 35 under the action of gravity, and finally flow into the interior of the collection box 33 through the collecting pipe 36 to complete the unified cleaning or recycling.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
