  The trial hitting station 8 is disposed in the vicinity of the application work position P1 of the substrate 200 in plan view (see FIG. 1). The trial hitting station 8 is mainly configured by a test hitting portion 81 including a winding portion 811 and a test hitting surface 812. The trial hitting station 8 is provided for performing trial hitting of the coating agent 300 before the coating agent 300 is applied to the substrate 200 by the coating units 71a to 71c. By this trial strike, it is possible to confirm whether or not a predetermined appropriate amount of the coating agent 300 is applied from the application units 71a to 71c.

  The winding unit 811 includes a motor (M). In addition, the winding unit 811 is configured to be able to move the trial hitting surface 812 on which the trial hit has been performed. Specifically, the winding unit 811 is configured to be able to wind the test hitting surface 812 in the R1 direction by a predetermined amount.

  The test hitting surface 812 is configured so that the test hitting of the coating agent 300 is performed. The test hitting surface 812 is configured by the surface of a sheet member 812a such as paper or film that can transmit light. The trial striking surface 812 (sheet member 812a) is wound in a roll shape, and the end on the opposite side (X1 side) to the end on the winding core side is connected to the winding unit 811. Further, a portion of the test hitting surface 812 in the vicinity of the test hitting position T is arranged to extend in a substantially horizontal direction (X direction) in a state where a predetermined tension is applied. Further, the test hitting surface 812 on which the coating agent 300 has been test hit is wound up by the winding unit 811. When the test surface 812 is wound up in a roll shape, it is removed and replaced with a new one. That is, the test hitting surface 812 is disposable.

  The imaging unit 9 is constituted by, for example, a CCD (Charge Coupled Device) camera. The imaging unit 9 is fixed at a position different from the head unit 7. Specifically, the imaging unit 9 is fixed at a position below the test hitting station 8 (below the test hitting surface 812) (Z2 side). Specifically, the imaging unit 9 is configured to be fixed at a position immediately below the trial hitting position T and to fit the trial hitting position T in the imaging visual field region. In addition, the imaging unit 9 is fixed at a substantially central position in the X direction of the test hitting surface 812 arranged so as to extend in the substantially horizontal direction (X direction) in the vicinity of the test hitting position T when viewed from the side surface (Y direction). ing. Further, the imaging unit 9 is configured to capture an image of the coating agent 300 applied to the test hitting surface 812 from below (Z2 side). Moreover, the imaging part 9 is comprised so that the coating agent 300 may be imaged in the state irradiated with illumination light from the illumination part 72a (72b, 72c). In the example shown in FIG. 2, since it was determined that the amount of the coating agent 300 that was trial-tested at the first time and the second time was not an appropriate amount, it was trial-struck at the third time (the coating conditions were changed from the first time and the second time). This shows a state in which the coating agent 300 that has been trial hit) is imaged.

  The storage unit 10 stores a program used when controlling the coating apparatus 110, information on an appropriate amount of the coating agent 300, and the like.

  The CPU 11 controls the entire coating apparatus 110 based on a predetermined program stored in the storage unit 10. In addition, the CPU 11 causes the application units 71a to 71c to perform trial application of the application agent 300, and determines whether or not the application units 71a to 71c can appropriately apply a predetermined amount of the application agent 300. It is configured to judge.

  Specifically, the CPU 11 causes the imaging unit 9 to capture an image of the coating agent 300 (one lump coating agent 300) applied by one trial hit by the coating unit 71a (71b, 71c). The image is analyzed (analysis of whether or not the trial-applied coating agent 300 is an appropriate amount). Further, the CPU 11 is configured to perform control to change the application condition based on the analysis result (analysis result of whether or not the trial-applied application agent 300 is an appropriate amount). Then, when the application amount of the trial-applied application agent 300 is not appropriate, the CPU 11 moves the test application surface 812 in the direction of the predetermined amount R1 to change the application condition again, and then apply the application agent 300 again. It is configured to perform control for trial hitting. The CPU 11 is configured to control the imaging unit 9 to capture an image of the coating agent 300 that has been trial hit again. As described above, when the trial hit is performed a plurality of times, the head unit 7 does not move from the initial position (the position where the first trial hit is performed) in plan view.

  Next, with reference to FIG. 2 and FIG. 3, the application amount suitability determination processing flow executed by the CPU 11 of the coating apparatus 110 according to the first embodiment will be described. The application amount suitability determination process is performed before the coating agent 300 is applied to the first substrate 200 when, for example, a predetermined number (a predetermined lot) of substrates 200 is manufactured. Moreover, below, the case where the coating amount suitability determination process about the application part 71b is performed is demonstrated. Since the application amount suitability determination process for the application unit 71a (71c) is the same as the application amount suitability determination process for the application unit 71b, description thereof will be omitted.

  As shown in FIG. 3, in step S <b> 1, the CPU 11 performs a process of moving the head unit 7 above the trial hitting station 8. That is, the application part 71b is moved above the trial hitting position T.

  Next, in step S2, the CPU 11 performs a process for executing a trial hit. Specifically, the CPU 11 moves the application unit 71b of the head unit 7 downward (Z2 side), and causes the test hitting surface 812 to execute test hitting based on the current setting.

  Next, in step S <b> 3, the CPU 11 performs a process of capturing an image of a portion in contact with the trial hitting surface 812 of the coating agent 300 that is trial hit by the imaging unit 9. Specifically, the CPU 11 captures a portion (lower surface image) in contact with the test hitting surface 812 of the coating agent 300 at the test hitting position T from below the test hitting surface 812 (Z2 side) via the sheet member 812a. 9 is imaged. At this time, the imaging unit 9 images the coating agent 300 (one lump coating agent 300) applied by one trial hit.

  Next, in step S <b> 4, the CPU 11 performs a process for acquiring the area of the coating agent 300. Specifically, the CPU 11 acquires the area of the portion that contacts the test hit surface 812 of the coating agent 300 based on the image captured in step S3.

  Next, in step S5, the CPU 11 performs a process of determining whether or not the coating amount of the coating agent 300 is appropriate. Specifically, the CPU 11 compares the area acquired in step S4 with the appropriate amount information (appropriate area) of the application agent 300 stored in advance in the storage unit 10, thereby applying the application amount of the application agent 300. It is determined whether or not is appropriate. At this time, the CPU 11 determines whether or not the application amount is appropriate from the image of the application agent 300 (one lump application agent 300) applied by one trial hit by the application unit 71b. When the application amount of the coating agent 300 is appropriate, the CPU 11 advances the process to step S8. On the other hand, when the application amount of the coating agent 300 is not appropriate, the CPU 11 advances the process to step S6.

  When the process proceeds to step S6, the CPU 11 performs a process of changing the application condition. Specifically, when the application amount (area) of the trial-applied coating agent 300 is smaller (smaller) than the appropriate amount (appropriate area), the CPU 11 increases the opening time of the valve 6b and performs the test application. When the coating amount of the coating agent 300 is larger than the appropriate amount, control for shortening the opening time of the valve 6b is performed.

  Next, in step S <b> 7, the CPU 11 performs a process of moving the test hitting surface 812. Specifically, the CPU 11 sets the trial hitting surface 812 (sheet member 812a) on the winding unit 811 so that the portion of the test hitting surface 812 where the coating agent 300 is not trial hit is disposed at the test hitting position T. To wind up. Thereafter, the CPU 11 returns the process to step S2.

  When the process proceeds to step S8, the CPU 11 performs a process of starting application on the substrate 200. Specifically, the CPU 11 moves the head unit 7 to the upper side (Z1 side) of the substrate 200 which is carried from the outside to the inside of the coating apparatus 110 and fixedly held at a predetermined coating work position P1. Then, the CPU 11 starts an application operation on the substrate 200 by the application unit 71b that can apply an appropriate amount of the application agent 300. Further, the CPU 11 causes the winding unit 811 to wind up the test hitting surface 812 so that a portion of the test hitting surface 812 where the coating agent 300 is not test hit is disposed at the test hitting position T. Thereafter, the CPU 11 ends the application amount suitability determination process.

  In the first embodiment, the following effects can be obtained.

  In the first embodiment, as described above, the imaging unit 9 is provided that images the coating agent 300 that is fixed to a position different from the head unit 7 and applied to the trial hitting station 8. Thereby, the imaging agent 9 fixed by the position different from the head part 7 can image the coating agent 300 (the lump of the coating agent 300) apply | coated by trial strike. As a result, when imaging the coating agent 300 applied by trial strike, unlike the configuration in which the imaging unit 9 moves, the imaging unit 9 does not move to capture the coating agent 300 applied by trial strike. It can suppress taking time.

  In the first embodiment, the imaging unit 9 is fixed to the lower part of the trial hitting station 8. Thereby, even when the imaging unit 9 is fixed, the trial hitting station is used after the trial hitting is performed by the application units 71a to 71c, compared to the case where the imaging unit 9 is fixed above the trial hitting station 8. 8 The image of the coating agent 300 can be taken at a position where trial hitting has been performed without moving the upper head portion 7.

The CPU 11 performs control for changing the conditions and moving the test hitting surface 812 to perform trial hitting of the coating agent 300 again, and then controlling the imaging unit 9 to pick up the image of the coating agent 300 that has been trial hit again. Configure. Thereby, after performing the test application of the coating agent 300 on a predetermined area of the test hitting surface 812, the test application is performed on another area different from the predetermined area of the test hitting surface 812, thereby changing the coating conditions. As a result, it is possible to easily change the coating conditions by performing trial hitting a plurality of times in succession. Further, since the application condition can be changed based on the analysis result of the image of the coating agent 300 (a lump of one coating agent 300) applied by one trial strike, the trial strike is performed a plurality of times. There is no need to change the conditions. As a result, the amount of the coating agent 300 used for trial hitting can be reduced.

  In the first embodiment, the imaging unit 9 is fixed below the test hitting surface 812, and the test hitting surface 812 that is the surface of the sheet member 812a is disposed in a state where a predetermined tension is applied. Further, the trial hitting station 8 is configured to include a winding unit 811 that can be moved by winding the trial hitting surface 812 on which the trial hit has been performed. Further, the imaging unit 9 is configured so as to image the coating agent 300 on the test hitting surface 812 movable by the winding unit 811 from below. Thereby, it is possible to suppress the trial hitting surface 812 from being bent when the coating agent 300 is trial hit. As a result, it is possible to prevent the shape of the coating agent 300 from being deformed when the test is hit. Thereby, the area of the part which contacts the trial hitting surface 812 of the coating agent 300 can be acquired correctly.

  In the first embodiment, the imaging unit 9 is fixed below the test hitting surface 812. In addition, the test hitting surface 812 is configured to transmit light, and the application units 71a to 71c are configured to apply the coating agent 300 that is not transparent or translucent. Thereby, it can suppress that the coating agent 300 permeate | transmits light. As a result, the area of the part of the coating agent 300 that comes into contact with the test striking surface 812 can be easily obtained.

  In the first embodiment, the illumination units 72 a to 72 c are arranged above the test hitting surface 812. Further, the imaging unit 9 is configured to image the coating agent 300 from below the test hitting surface 812 in a state where illumination light is irradiated from the illumination units 72a to 72c. As a result, the area of the portion of the coating agent 300 that contacts the trial hitting surface 812 that is reflected on the test hitting surface 812 can be accurately imaged by illumination light from above the test hitting surface 812.
