  • the position of the tip of the nozzle 22 of the discharge device 21 in the height direction is adjusted (STEP 12). Specifically, first, the Z-axis lowering amount when the value indicated by the distance measuring device 24 becomes the reference position on the surface of the touch sensor 30 is read, and then the discharge device 21 is lowered by the Z-axis driving mechanism 16 to thereby reduce the nozzle.
  • the height is measured by the distance measuring device 24 because the mechanical attachment error cannot be made zero. That is, the contact surface of the touch sensor 30 constituting the calibration unit 28 and the application surface of the adjustment work on the adjustment stage 29 are attached to be the same as the height of the application surface of the work fixed on the application stage 27. Is ideal, but the mechanical mounting error cannot be made zero. Therefore, the height at the time of calibration and the height at the time of application are measured, and the positional accuracy in the height direction of the discharge device 21 is improved by driving the Z-axis drive mechanism 16 in consideration of the difference (error). It is for illustration.
  • the position in the horizontal direction of the tip of the nozzle 22 is adjusted (STEP 13). Specifically, first, the application of a point, a line, or the like is actually performed on the work for adjustment, and then the point and the line applied by moving the nozzle and the imaging device by the same distance as the separation distance between the nozzle and the imaging device are displayed. Reflect in. If the applied point or line is located at the center of the projected image, the tip position of the nozzle 22 is as set. On the other hand, if the applied point or line is not located at the center of the projected image, the tip position of the nozzle 22 is shifted, so the distance from the center of the image to the applied point or line center is obtained and adjusted. Remember as a quantity. At the time of application, the nozzle tip is moved in consideration of this adjustment amount.
  • the coating amount is adjusted (STEP 14).
  • a method for measuring the application amount a method can be used in which the area and volume of the liquid material applied using the imaging device 23 and the distance measuring device 24 are obtained, compared with the set values, and the discharge amount adjusted.
  • the nozzle cleaning mechanism 31 removes dirt due to the liquid material that may adhere to the tip of the nozzle when it is applied in STEP 13 or STEP 14 (STEP 15).
  • the nozzle cleaning mechanism 31 for example, a type in which an air current is blown to the tip of the nozzle 22 to blow off the excess liquid material, a type in which the tip of the nozzle is sucked and the excess liquid material is sucked, or the like can be used.
  • the nozzle cleaning process may be performed periodically not only during the preparation stage but also during the coating stage described later. By doing so, an accurate amount can be applied in a good shape.
  • the above STEP 12 to STEP 15 may be performed automatically and continuously.
  • the first workpiece 11 is conveyed to the position of the coating stage 27 (STEP 24).

  • the loader-side stopper 32 rises to stop the workpiece 11 at the standby position.
  • the mounting table A46 of the loader 42 moves to the third workpiece taking-out position (STEP 28).
  • application is performed on the first workpiece 11 fixed by the application stage 27 (STEP 29), and after performing a desired application operation, the application stage 27 is lowered to release the fixation of the workpiece 11 ( (STEP 30).
  • the coated work 11 is transported to the magazine B45 of the unloader 43 and stored in the first work storage position of the magazine B45 (STEP 31). At this time, since the loader side (upstream side) stopper 32 is still raised, the second workpiece 11 at the standby position is not conveyed to the work position.
  • the loader side stopper 32 When the loading of the first workpiece 11 in the unloader side magazine A44 is completed, the loader side stopper 32 is lowered and transports the second workpiece in the standby position to the working position (STEP 32). At this time, similarly to STEP 24, the unloader-side stopper 32 is raised to stop the workpiece above the coating stage 27, and is lowered after the stop. Then, the application stage 27 is raised to fix the workpiece (STEP 33). Next, the third workpiece 11 is transported to the standby position (STEP 34). At this time, the stopper 32 on the loader side rises to stop the third workpiece 11 at the standby position. After taking out the third workpiece 11, the mounting table A46 of the loader 42 moves to the fourth workpiece taking-out position (STEP 35).
