Description

Technical Field

[0001] The invention relates to a surface treatment technology, in particular to a movable box-type integrated surface spraying treatment production line and a process method thereof. Background Art

[0002] With the increasing number of surface treatments for industrial products and the continuous improvement of quality requirements, labor costs have increased exponentially. At the same time, the country's requirements for environmental emissions have increased. As far as automobile surface treatment is concerned, the requirements for automobile appearance quality are also getting higher and higher. Therefore, higher and higher requirements are put forward for automobile surface treatment technology; traditional spraying technology is usually completed by manual operation. Although this spraying method is more flexible to operate, the spraying efficiency is low and the labor intensity is high. It is not suitable for current large-scale and large-scale production operations.

[0003] At present, many automobile companies in the market use automatic spraying production lines, which generally use chain drive to form a ring chain, concentrate the spraying process on the entire ring chain, form a flow operation, and improve the efficiency of spraying. However, this kind of ring chain operation method has high investment cost and occupies a large area of ​​factory buildings. Once the spraying production line is started, the equipment and operators of each workstation must be in place in time to realize automated production, resulting in high energy consumption of equipment and high labor costs. At the same time, it takes a long time to change the spray color, causing multiple workstations to run idle for a long time and poor maneuverability. Summary of the invention

[0004] In view of the above situation, the purpose of the present invention is to provide a movable box-type integrated surface spray treatment production line and its process method, which adopts the structural design of symmetrically setting the spraying area on both sides of the drying operation area combined with a mobile baking room to overcome the defects of the prior art using circular chain flow operations, with low investment cost, small occupied site area, fast spray color change, strong maneuverability, and the overall structure is scientific and reasonable, simple and compact, easy to install and use, with broad market prospects and easy to promote and use.

[0005] In order to achieve the above-mentioned purpose, a movable box-type integrated surface spraying processing production line is provided, which includes a movable drying system, a robot automatic spraying container, and an automatic workpiece transfer and docking conveying device; the robot automatic spraying container includes a box-type integrated first spraying area and a box-type integrated second spraying area, the movable drying system includes a box-type integrated drying operation area and a box-type integrated mobile baking room, the box-type integrated first spraying area and the box-type integrated second spraying area are symmetrically distributed at the opposite ends of the box-type integrated drying operation area, and the box-type integrated first spraying area and the box-type integrated second spraying area are respectively connected to the box-type integrated drying operation area via the automatic workpiece transfer and docking conveying device; the box-type integrated mobile baking room is located above the box-type integrated drying operation area, and the box-type integrated drying operation area includes 2 to 3 drying stations.

[0006] In order to achieve structural and effect optimization, further measures are: the 2 to 3 drying stations in the box-type integrated drying operation area are distributed adjacent to each other, and the 2 to 3 drying stations in the box-type integrated drying operation area are on the same straight line as the center line of the box-type integrated first spraying area and the box-type integrated second spraying area.

[0007] An online waste gas treatment device is provided at the upper end of the box-type integrated mobile baking room.

[0008] The present invention also provides a process for surface spraying treatment, which comprises the following steps:

[0009] 1) First, the workpiece to be sprayed is transported to the first spraying area of ​​the box-type integrated spraying area or the second spraying area of ​​the box-type integrated spraying area, and then the workpiece is sprayed by the robot;

[0010] 2) The workpiece that has completed the spraying operation is transferred to an empty drying station in the box-type integrated drying operation area through the workpiece automatic transfer and docking conveyor. The empty drying station should be at the shortest distance from the workpiece spraying operation area to save transportation time and shorten the transportation distance;

[0011] 3) The box-type integrated mobile baking room is transferred to the top of the empty drying station, and then the box-type integrated mobile baking room is lowered to cover the workpiece to dry the workpiece. When the drying operation is started, as the temperature rises and reaches the set temperature, the online exhaust gas treatment device installed at the upper end of the box-type integrated mobile baking room starts to operate and treat the exhaust gas;

[0012] 4) After the drying operation is completed, the box-type integrated mobile baking room is raised and separated from the workpiece, and then the box-type integrated mobile baking room is transferred to the next drying station for drying operation;

[0013] 5) Transport the dried workpieces to the warehouse from the side of the drying station;

[0014] 6) Repeat the above steps 1) to 5) to form a continuous cycle operation.

[0015] In order to achieve process and effect optimization, further measures are as follows: in the step 1), the first box-type integrated spraying area and the second box-type integrated spraying area can be sprayed with different colors of paint respectively or with the same color of paint respectively; when the spraying color needs to be changed, the spraying color of any one of the first box-type integrated spraying area and the second box-type integrated spraying area can be changed first without affecting the work of the other spraying area, and then the spraying color of the other spraying area can be changed, and by alternating replacement, cyclic continuous operation can be achieved.

[0016] The beneficial effects of the present invention compared with the prior art are as follows:

[0017] (I) The present invention adopts symmetrical arrangement of spraying areas on both sides of the drying operation area, which is convenient for spraying different colors of paint separately. When the spraying color needs to be changed, the color can be changed in any spraying area first, and the other spraying area can continue to spray, which will not cause the production line to run idle, has strong mobility, and can significantly reduce the operating cost;

[0018] (II) The present invention adopts a mobile baking room structure, which can be combined with any drying station by moving the baking room. Compared with the existing ring chain production line, it occupies a small area, has a low investment cost, and has a simple overall structure and safe and reliable operation;

[0019] (III) The spraying area, drying operation area and mobile baking room in the present invention all adopt a box-type integrated structure. Compared with the existing ring chain production line, the equipment is simple to install and disassemble, and the overall transportation is convenient, which greatly reduces the on-site workload of after-sales service personnel and has a high user satisfaction;

[0020] (IV) The present invention adopts a box-type integrated mobile drying room with an online exhaust gas treatment device at the upper end, which can timely treat the exhaust gas generated by the drying operation, which is beneficial to protecting the environment and achieving the purpose of energy saving, environmental protection and high efficiency;

[0021] (V) The present invention adopts a structural design in which the spraying areas are symmetrically arranged on both sides of the drying operation area and is combined with a mobile baking room, thereby overcoming the defects of the prior art in which the ring chain flow operation is adopted. The investment cost is low, the occupied site area is small, the spraying color can be changed quickly, the maneuverability is strong, and the overall structure is scientific and reasonable, simple and compact, and is easy to install and use, with significant economic and social benefits.
