Description

Technical Field

[0001] The utility model relates to automobile wheel hub manufacturing technology, in particular to a novel single-station wheel hub spray painting room. Background Art

[0002] The wheel hub is an important load-bearing and appearance component of a car. The surface of the wheel hub needs to be painted to ensure its beauty and corrosion resistance.

[0003] The existing wheel hub painting process is that the conveyor chain carries the wheel hub to the paint spraying room for continuous passing painting. In order to increase production capacity, the production chain speed of the spraying line is relatively high (400 pieces / hour-500 pieces / hour). In order to ensure the painting effect of the wheel hub under the high chain speed, multiple spray guns need to be arranged in series in the paint spraying room, and multiple stations and multiple wheel hubs are sprayed at the same time, resulting in the paint spraying room being relatively large in size (7 meters-9 meters). Due to the large size of the paint spraying room, it is impossible to form a modular construction and installation, and all parts are assembled and welded, resulting in a relatively long construction process and a relatively high overall investment cost.

[0004] In addition, due to the large size of the paint room and the environmental protection requirements for the paint room, a high-power air conditioning air circulation system and a Venturi water curtain circulation system are required during the wheel hub painting process to capture the large amount of waste generated during the wheel hub painting process. The energy consumption and environmental protection costs in production operations are relatively high. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a new single-station wheel hub spray paint room.

[0006] According to the utility model, a new type of single-station wheel hub spray paint booth is provided, comprising: a spray paint booth main body with a built-in robot spraying system, a rotating device for driving a wheel hub rotating bracket, paint mist catching cotton arranged on the inner wall of the spray paint booth, and an automatic door used as a spray paint booth door, wherein a supply reel is installed on the top of the inner wall of the spray paint booth, and a recovery reel is correspondingly installed on the bottom, the paint mist catching cotton is rolled and installed on the supply reel and connected to the recovery reel, and the supply reel and the recovery reel are connected in a synchronously rotating transmission manner.

[0007] Preferably, the rotating device comprises: a jet pipe arranged at the bottom of the paint spraying room, and an impeller arranged at the bottom of the hub rotating support.

[0008] Preferably, the paint spraying room body is provided with air conditioning air circulation and water circulation systems.

[0009] Preferably, the water circulation system comprises a water pump for supplying water to the jet tubes.

[0010] Preferably, the paint mist capturing cotton is arranged on the inner wall of the paint room side panel of the paint room body and / or the inner wall of the automatic door.

[0011] Preferably, the supply reel and the recovery reel are driven via a chain.

[0012] The beneficial effects of the utility model are:

[0013] 1. Compared with the spraying lines with the same production capacity, the land area of ​​2 new wheel hub spray booths (2 meters to 3 meters) can be reduced by about 1 / 3. In addition, due to the reduced size of the spray booth, the power of the air conditioning air circulation system and water circulation system required by environmental protection is reduced by about 1 / 2; the self-recycling paint mist capture cotton replaces the side water curtain of the Venturi water curtain circulation system, further reducing the water consumption; the overall production and operation costs are effectively reduced. At the same time, due to the small size of the spray booth, the time required for daily production and maintenance is relatively short, which further improves production efficiency.

[0014] 2. The new wheel hub spray paint room of the utility model is designed and manufactured as a modular whole. During the construction and installation process, the spray paint room can be installed as soon as it is in place, which greatly saves the installation construction period and construction investment cost. In addition, because the paint room is modular, when the production line is upgraded and renovated for production capacity, the new modular spray paint room can be directly connected in parallel without demolishing the original paint room, which greatly reduces the impact on production.

The following description of each embodiment emphasizes the differences between the embodiments. The same or similar aspects can be referenced to each other. For the sake of brevity, they will not be described one by one. The technical features in different embodiments can be freely combined according to design requirements to form more embodiments.

[0021] Reference Figures 1 to 3 A new type of single-station wheel hub spray paint room of the utility model is described in detail as follows.

[0022] The utility model provides a new type of single-station wheel hub spray painting room, including:

[0023] The main body of the spray booth 1 includes an air-conditioning air circulation and water circulation system, and a robot spraying system 5 is provided inside to spray paint the wheel hub with a robot;

[0024] The rotating device 2 is used for self-rotation during wheel hub spraying. Different from the common motor-driven rotating station drive form of the current production line, this equipment adopts a water-rotating mechanism and does not require a motor drive. The working principle is that after the conveying device transports the wheel hub rotating bracket 21 to the position, the jet tube 22 arranged below the liquid level at the bottom of the paint room ejects water (the water flow can be powered by a water pump), and the water flow hits the impeller 23 at the bottom of the wheel hub rotating bracket 21. The impeller 23 drives the rotating bracket 21 to rotate, thereby realizing the rotation of the wheel hub. At the same time, by controlling the opening and closing and flow rate of the ejected water flow, the start and stop of the wheel hub rotation and the rotation speed can be controlled;

[0025] The self-recoverable paint mist capture cotton 3 is used to capture the waste paint mist generated during the spraying process and is arranged on the inner wall of the main body 1 of the paint spray booth (including the inner wall of the paint booth side panel and the inner wall of the automatic door). Taking the inner wall of the paint booth side panel as an example, the principle is to install a supply reel 31 on the top of the paint booth side panel, and correspondingly install a recovery reel 32 on the bottom of the paint booth side panel. The rolled paint mist capture cotton 3 is installed on the supply reel 31 at the top, and connected to the recovery reel 32 through the paint booth side panel. The upper and lower reels rotate synchronously through a mechanical structure (such as a chain drive). Under the initial condition (when the paint mist capture cotton 3 near the side panel does not capture the paint mist), the two reels are in a static equilibrium state. According to the change in its own weight after capturing the paint mist, the supply reel 31 and the recovery reel 32 are driven to rotate at the same time, so that the paint mist capture cotton 3 with paint is automatically rolled into the recovery reel 32 at the bottom. No motor or other device is required to drive it, which further improves the safety of the paint spray booth. Compared with the traditional Venturi water curtain circulation system, the water curtain on the inner wall of the paint room captures the paint mist attached to the side panel by water circulation. This design completely eliminates the need for water for the side panel of the paint room, which is more environmentally friendly and further reduces production costs.

[0026] The automatic door 4, as the spray booth door of the main body 1 of the spray booth, is automatically closed when the wheel hub is sprayed, and a stable wind flow from top to bottom is formed inside the paint booth through the action of the circulating fan; when the driving motor (or cylinder) of the automatic door 4 receives the spraying completion signal in the paint booth, the automatic door 4 is driven to open to allow the next wheel hub to enter. The automatic door 4 is also arranged with a self-recovering paint mist capture cotton 3;

[0027] The robot spraying system 5 is used to spray paint the wheel hub.

[0028] The robot of the robotic spraying system 5 carries multiple spray guns and can achieve "0" second switching of multiple colors.

[0029] The operation process of the new single-station wheel hub spray booth may include the following steps:

[0030] S1, the automatic door 4 at the entrance of the spray booth is opened, and the wheel hub passes through the conveying system and enters the main body 1 of the spray booth;

[0031] S2, the automatic door 4 at the entrance closes automatically, the rotating device 2 starts, and the robot spraying system 5 starts spraying paint;

[0032] S3. After the robot finishes painting, the automatic door 4 at the exit opens, and the wheel hub leaves the main body 1 of the paint spraying room through the conveying system; at the same time, the automatic door 4 at the entrance opens, allowing the next wheel hub to enter.

[0033] The utility model can realize modular integrated design and manufacturing. Due to the small size and monomer design of the paint room, the main body 1 of the paint room can be manufactured in advance in the factory, and the rotating device 2, the self-recycling paint mist capturing cotton 3, the automatic door 4, and the robot spraying system 5 can be fixed in the corresponding positions in advance to form a whole with the main body 1 of the paint room, and can be shipped and installed in an integrated manner.

[0034] In the description of the present application, "multiple" means two or more than two, unless otherwise clearly and specifically defined. Unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. Although the present invention has been described with reference to various specific embodiments, it should be understood that variations can be made within the spirit and scope of the concept of the described utility model. Therefore, it is intended that the present invention is not limited to the described embodiments, but will have the full scope defined by the language of the appended claims.
