Problems solved by technology

[0003] Existing automobile painting equipment needs to spend a lot of man-hours to stop the line for cleaning when changing primers of different colors, which will have obvious adverse effects on production efficiency, production quality and cost control. However, automobiles based on existing automobile painting equipment The cumbersomeness of the primer spraying process further increases the difficulty of cleaning. In order to overcome this defect, the present invention provides a method that can greatly reduce the downtime of the line and reduce the impact of pipeline cleaning on production when the primer is switched. , improve production efficiency, ensure production quality, and be beneficial to cost control automobile coating primer avoiding miscellaneous paint device and application of the device's miscellaneous paint avoiding method

Embodiment 1

[0026] Such as figure 1 Shown, a kind of car coating primer avoids miscellaneous paint device, is located at the intersection of the paint transmission and mixing pipeline 28 of each color primer, at the intersection, the transmission and mixing paint pipeline 28 of each color primer is parallel upwards, and each color primer The paint transmission and mixing pipelines 28 are all fixed by fixed mounts, so that the paint transmission and mixing pipelines 28 of various colors of primers possess higher external pressure bearing capacity. The car paint primer and miscellaneous paint avoidance device includes a frame 1, a rotating frame 2 and two parallel alternate interchange pipes 3, and the rotating frame 2 is rotatably connected to the frame 1 and is connected to a driving device. The driving device is a Swing cylinder 26, the swing range of swing cylinder 26 is 180 °. The alternate junction pipe 3 is connected to the outer edge of the rotating frame 2, and the alternate junct...

Embodiment 2

[0033] Such as figure 2 As shown, each pivot arm 7 includes two parallel arms, one end of the arm is fixedly connected to the rotating shaft 6, and the arm is in a Z shape, and the free end of the arm is bent downward by 90° and then extended horizontally to rotate the junction pipe 3 Slidingly connected to the horizontal extension section of the free end of the arm, the single intersection interface 4 is located on the side of the alternate intersection pipe 3 . The rotating shaft 6 is in the vertical direction, and the center of the rotating shaft 6 is provided with an axially through center hole. One end of the rotating shaft 6 is rotationally connected with a platform on the frame 1, and the other end of the rotating shaft 6 is connected with a driving device through a gear transmission mechanism. The driving device is a servo motor, and the servo motor is fixed on a pillar passing through the central hole of the rotating shaft and fixedly connected to the platform. Back...

Embodiment 3

[0035]The driving device is a servo motor. The rotating frame 2 is in the shape of a cross when viewed from the axial direction, and there are four alternating interchange pipes 3, which are respectively slidably connected to the four groups of arms of the rotating frame 2. Each group of arms is composed of three parallel arms, and the four groups of rotating arms 7 are connected to each other. Forming an included angle of 90°, two of the four alternate junctions 3 are alternate junctions with dark gray primer, two are alternate junctions with light gray primer, alternate junctions with dark gray primer and alternate junction with light gray primer Install at intervals on the rotating frame 2. Mobile seat slide rail 23 is horizontally arranged. When the new rotation junction pipe 3 is transferred to the nozzle of the paint delivery and mixing pipeline 28, the sealing ring on the single junction interface 4 can realize the sealing connection with the paint delivery and mixing ...

Abstract

The invention discloses a miscellaneous paint avoiding device for automobile priming paint coating. The miscellaneous paint avoiding device for automobile priming paint coating is arranged at the junction of paint conveying and adjusting pipelines of various colors of priming paint, and at the junction, the paint conveying and adjusting pipelines of the various colors of priming paint are parallel. The miscellaneous paint avoiding device for automobile priming paint coating comprises a rack, a rotary frame and at least two parallel alternate joining pipes. The rotary frame is rotationally connected to the rack and is in transmission connection with a drive device. The alternate joining pipes are connected to the outer edge of the rotary frame. Each alternate joining pipe is provided with ajoining connector which can be connected with the paint conveying and adjusting pipeline of the priming paint in a butt joint manner and a joining outlet, wherein the joining outlet is connected witha paint supply pipe of paint spraying equipment in a butt joint manner, a paint supply pipe butt joint of the spraying equipment is fixedly arranged on a paint supply pipe butt joint pulling and inserting mechanism, and an alternate joining pipe residual priming paint removing mechanism is arranged below the rotary frame. The invention further discloses a miscellaneous paint avoiding method applying the device.

Description

technical field [0001] The present invention relates to a kind of automobile painting equipment and the process of using the equipment, more specifically, it relates to a kind of automobile painting primer and avoiding miscellaneous paint device and the method of using the device to avoid miscellaneous paint. Background technique [0002] Automobile primer is the first paint applied directly on the surface of the car body after surface treatment. The paint has good compatibility, and must also have good corrosion resistance, rust resistance, oil resistance, chemical resistance and water resistance, as well as good hiding power. The most commonly used primers in the conventional body painting process are black, gray and white. Each color requires a separate set of paint transfer system. On the other hand, due to the constraints of installation space and cost, even in the There is only one spraying equipment at the end of the three-color primer-transporting paint system. The ...
