Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a coating device that continuously forms a film of a constant thickness on the surface of an electronic device medium or the like.

BACKGROUND OF THE INVENTION In recent years, coating equipment has been replaced by manual work with automation, and the quality of products has become increasingly stable.

An example of a conventional coating apparatus will be described below with reference to the drawings.

FIG. 5 shows a front sectional view of a conventional coating apparatus. In FIG. 5, 1 is the main body of the coating apparatus, 2 is a helical-shaped coating chamber, and 3 is a sealed coating chamber.
4 is an opening/closing window for supplying or taking out the product 3; 5 is a rotating head that can rotate while holding the product; 6
8 is a nozzle for applying the coating liquid; 9 is a box for receiving the liquid; 10 is a rotating arm that supports the rotating head 5 and rotates around the shaft 7; A scattering plate 11 is used to prevent the applied liquid from scattering, and a heater is used to heat the product 3.

The operation of the conventional coating apparatus configured as described above will be described below.

First, the operator opens the opening/closing window 4 and attaches the product 3 to the tip of the rotating head 5, which is at position a and has stopped rotating.
Close the opening/closing window 4. Next, the rotating arm 6 supporting the rotating head 5 rotates 45 degrees around the axis 7, and when it reaches position b and stops, the rotating head 5 continuously rotates and sprays the coating liquid from the nozzle 8 onto the product 3. flow to. Next, the rotating arm 6
When the product 3 rotates 135'' and reaches position C and stops, the rotating head 5 rotates at high speed to spin, scattering excess liquid on the product 3 and making the film uniform.Next, the product 3 is rotated. When the arm 6 rotates further by 90'' and comes to the position d and stops, the rotary head 5 is heated by the heater 11 while rotating, thereby curing the film uniformly applied on the product 3. Subsequently, when the turning arm 6 turns another 90 degrees to the original position a, the operator opens the opening/closing window 4 and takes out the product 3 from the stopped rotating head 5.

Problems to be Solved by the Invention However, in the conventional configuration as described above, the rotary head 5 to which one product 3 is attached sequentially passes through the steps of supplying, applying the coating liquid, spinning, curing, and taking out the product. Therefore, it takes a long time to complete the coating of one product 3, resulting in a problem of poor productivity.

Furthermore, since the position of each processing step is fixed and the angle of the product 3 held by the rotary head 5 is also constant during that processing step, the angle of the product 3 can be changed to set the optimum processing conditions. The problem was that it was not possible.

In view of the above-mentioned problems, the present invention has the same number of rotating heads as the number of processing steps, and the rotating heads are intermittently conveyed through each step by a driving means, thereby significantly improving productivity through continuity. The angle of the rotating head that holds the product can be freely changed.
The objective is to provide a coating apparatus that can achieve 0 optimal conditions 0 settings 8 (1).

Means for Solving the Problems In order to solve the above problems, the coating apparatus of the present invention is connected to a loop-shaped drive transmission means at regular intervals, and intermittently moves in a horizontal plane while being supported and guided by a fixed guide. a plurality of carts circulated by the carts, a swinging arm that performs an initial swinging motion at a constant angle by engagement with a first external drive means around a horizontal shaft pivotally supported by each of the carts; a rotating head that is attached to the tip of a rotating shaft that is supported perpendicularly to the shaft and that is continuously rotated by engagement with a second external drive means and has a product clamping function; a part of the cart and a swinging arm; The machine is equipped with a plurality of processing chambers, each of which has a built-in rotary head, and whose adjacent portions are partitioned off from each other.

Effect of the present invention With the above-described configuration, a rotary head that rotates while holding the same number of products as processing steps is attached to a plurality of carts, and is intermittently conveyed in a horizontal plane between each step, thereby making it possible to continuously coat. is possible, greatly improving productivity. In addition, each trolley is provided with a swinging arm that swings to a desired angle by an external drive means to set the angle, and that pivots the rotating head, so that the product held by the rotating head can be adjusted. Since the angle can be arbitrarily selected, the optimum coating conditions can be set.
