- FIG. 4 is a flowchart showing an example of an adhesive application routine executed by the CPU 62 of the control device 60.
- This routine is stored in the storage unit 64 of the control device 60, and is executed in a state in which the coating process is ready, such as the substrate S being transported to a predetermined position by the substrate transport device 12 and held.
- the control device 60 Before executing this routine, it is assumed that the control device 60 has acquired a job that defines in what order the adhesive is applied to the plurality of application positions of the substrate S.
- the coating position is set corresponding to the position where the component is mounted.
- the CPU 62 When the CPU 62 starts the adhesive coating routine, it first sets the first coating position as the coating target (S110). Subsequently, the CPU 62 moves the needle 44b of the coating nozzle 44 to the coating position to be coated (S120). Specifically, the CPU 62 controls the X-axis motor 22a and the Y-axis motor 24a to operate the X-axis slider 22 and the Y-axis slider 24 to position the needle 44b directly above the coating position to be coated. At this time, the height of the tip of the needle 44b is set to a height (standby position) that does not collide with surrounding members or the like when the needle 44b moves in the XY direction.
- the CPU 62 controls the coating head 30 to apply the adhesive from the needle 44b to the coating position to be coated (S130). Specifically, the CPU 62 controls the Z-axis motor 34c to lower the needle 44b on the Z-axis slider 34 from the standby position to the descending end, and then raise it from the descending end to the standby position. At the same time, the CPU 62 switches the coating valve 50 from off to on at a predetermined valve on timing (supply start timing) to supply the liquid agent to the needle 44b, and then presses the adhesive with compressed air for a predetermined coating time. Waiting for the elapse of time), the coating valve 50 is switched from on to off to stop the supply of the liquid agent to the needle 44b.
- a predetermined valve on timing supply start timing
- the valve-on timing is stored in the storage unit 64, and is read out and used by the CPU 62. Further, the CPU 62 controls the Z-axis motor 34c so that the needle 44b rises after the tip of the needle 44b reaches the descending end and the coating valve 50 is switched off.
- the valve on timing is arbitrarily set by the operator as described later. The set valve-on timing is applied to all the coating positions of one substrate S.
- the CPU 62 determines whether or not the application of the adhesive to all the application positions has been completed (S140). If it has not been completed in S140, the CPU 62 sets the unprocessed coating position as the coating target (S150), and executes the processing after S120 again. On the other hand, if the application of the adhesive to all the application positions has been completed in S140, the CPU 62 ends this routine.
- FIG. 5 is a flowchart showing an example of a valve-on timing setting routine.
- This routine is stored in the storage unit 64 of the control device 60, and is started when the operator instructs the input device 72 to call the setting screen.
- the CPU 62 displays a setting screen on the display 70 (S210).
- the operator arbitrarily sets the valve on timing on the setting screen using the input device 72.
- the valve on timing is set by the height [mm] from the descending end of the needle 44b.
- the CPU 62 determines whether or not the valve on timing has been input (S220), and if not, waits as it is. On the other hand, if the valve-on timing is input in S220, the CPU 62 updates the previous valve-on timing stored in the storage unit 64 to the valve timing input this time (S230), and ends this routine.
- FIG. 6 is a time chart showing an example of the operating state of the coating head 30 executing the process of S130.
- the valve-on timing is the timing at which the needle 44b reaches a predetermined height (for example, 4 mm or 5 mm) from the descending end after the descent of the coating head 30 starts.
- the height of the needle 44b may be obtained based on the Z-axis command position or may be obtained based on a detection signal of an encoder (not shown) attached to the coating head 30.
- the coating valve 50 After the coating valve 50 is turned on, it waits for a predetermined coating time to elapse. Compressed air continues to be supplied to the syringe 42 of the coating head 30 until the coating time elapses.
- the predetermined coating time is set based on the coating diameter, viscosity, and the like of the adhesive. For example, when a low-viscosity adhesive is used, the coating time is set short, and when a high-viscosity adhesive is used, the coating time is set long.
- FIG. 6 is an example in which the coating time is set to be relatively short.
- the valve on timing is set so that the coating time elapses before the tip of the needle 44b of the coating nozzle 44 reaches the descending end. Therefore, there is a certain amount of time from when the coating time ends and the coating valve 50 is turned off until the needle 44b reaches the descending end (residual pressure release time). Since the residual pressure in the syringe 42 is released by utilizing this time, it is possible to prevent liquid leakage after the needle 44b is raised. Further, since the needle 44b can start ascending immediately after reaching the descending end, the tact becomes appropriate.
- FIG. 7 is also a time chart showing an example of the operating state of the coating head 30 executing the process of S130.
- the valve-on timing is set to the same timing as in FIG. 6, but the coating time is set to be longer than that in FIG. Specifically, the coating time continues even after the needle 44b reaches the descending end. Therefore, the needle 44b waits at the descending end until the coating time ends after the needle 44b reaches the descending end. That is, after the tip of the needle 44b reaches the descending end, it takes a relatively long time to start ascending the needle 44b (waiting time at the descending end). As a result, tact increases and productivity decreases.
- FIG. 8 is a time chart showing an example of the operating state of the coating head 30 executing the process of S130.
- the coating time is set to the same length as that of FIG. 7, but the valve on timing is from FIG. 7. Is set early.
- the valve on timing is set at the time when the needle 44b starts descending. In other words, the valve on timing is set so that the waiting time at the descending end approaches zero as compared with FIG. 7. As a result, the increase in tact can be suppressed as compared with FIG. 7.
- the valve on timing is arbitrarily set by the operator. Therefore, it is possible to eliminate the inconvenience that occurs when the valve on timing is constant.
- the valve on timing is set so that the coating time elapses before the tip of the coating nozzle 44 reaches the descending end.
- the tip of the coating valve 50 can be kept at the descending end for a while (residual pressure release time) after the coating valve 50 is turned off. Therefore, during that time, the residual pressure in the coating nozzle 44 decreases, and it is possible to prevent liquid leakage after the coating nozzle 44 rises.
- the valve on timing is set so that the time from when the tip of the coating nozzle 44 reaches the descending end to when the coating nozzle 44 starts to rise approaches zero. This makes it possible to shorten the waiting time at which the tip of the coating nozzle 44 stays at the descending end. Therefore, it is possible to prevent an increase in tact.
- the valve-on timing is set by the operator, but it may be set by the control device 60.
- the control device 60 stores in advance the correspondence relationship between the type of adhesive and the valve-on timing in the storage unit 64, and the valve-on timing is based on the correspondence relationship based on the type of adhesive used. May be set. Since the adhesive has different characteristics (for example, viscosity) depending on the type of the adhesive, the valve on timing suitable for the type of the adhesive is stored in the storage unit 64 in advance. In this way, it is possible to set the valve on timing suitable for the type of adhesive.
- the control device 60 sequentially adopts a plurality of predetermined provisional valve-on timings to determine the adhesive application condition by the application nozzle 44, and the adhesive application condition is appropriate.
- the provisional valve-on timing may be stored in the storage unit 64 as the valve-on timing.
- the provisional valve on timing may be set, for example, from the descending end of the needle 44b to the standby position every 1 [mm].
- the degree of application of the adhesive can be determined by applying the adhesive to the paper medium 57 of the trial striking unit 56. For example, an image of the adhesive applied to the paper medium 57 is captured by the mark camera 54, and the size of the adhesive diameter and satellites (droplets after the adhesive is scattered) are determined from the image.
- the liquid agent coating device 10 is exemplified as an example of the liquid agent coating device of the present disclosure, but the work used for component mounting of a commonly known component mounting device (see, for example, Japanese Patent Application Laid-Open No. 2016-115910).
- a head replaced with a coating head 30 may be used.
- the valve on timing is applied to all the coating positions of one substrate S, but is not particularly limited to this.
- an adhesive is first applied to a single substrate S by a coating nozzle 44 having a nozzle diameter a [mm], and then the adhesive is applied by replacing the coating nozzle 44 with a nozzle diameter b [mm] in the middle.
- the valve-on timing may be set for each nozzle diameter, and the valve-on timing corresponding to the nozzle diameter may be applied.
- the valve on timing may be set for each coating position of one substrate S, and the valve timing corresponding to the coating position may be applied.
- valve-on timing is set by the valve-on timing setting routine, but the present invention is not particularly limited to this.
- the valve-on timing may be set by a setting file that can be edited by the operator as a text file, and may be transferred to the storage unit 64 of the control device 60 and updated by the file transfer protocol.
- the valve on timing is set by the height [mm] from the descending end of the needle 44b, but the valve is not particularly limited to this.
- the valve on timing may be set to a time [msec] that is advanced by the coating time (or coating time + ⁇ ) from the estimated time when the needle 44b reaches the descending end.
- the estimated time is preferably set so that the time from when the needle 44b reaches the descending end to when the needle 44b rises is as short as possible (that is, zero or close to zero).
- the adhesive is exemplified as the viscous fluid, but the adhesive is not particularly limited, and for example, cream solder or a conductive paste may be used.
- the liquid agent coating device of the present disclosure may be configured as follows.
- the supply start timing is set so that the time from when the tip of the coating nozzle reaches the descending end to when the coating valve starts to rise becomes zero or approaches zero. May be good. By doing so, the waiting time at which the tip of the coating nozzle stays at the descending end can be shortened as much as possible, so that the increase in tact can be prevented.
- the supply start timing may be set so that the predetermined time elapses before the tip of the coating nozzle reaches the descending end.
- the tip of the coating valve can be kept at the descending end for a while after the supply of the liquid to the coating nozzle is stopped, so that the residual pressure in the coating nozzle is lowered during that time, and the liquid from the tip of the coating nozzle is reduced. Can prevent leakage.
- the supply start timing is set by the control device, and the control device stores in advance a correspondence relationship between the type of the liquid agent and the supply start timing in the storage unit.
- the supply start timing may be set from the correspondence relationship based on the type of the liquid agent to be used. By doing so, it is possible to set the supply start timing suitable for the type of the liquid agent.
- the supply start timing is set by the control device, and the control device sequentially adopts a plurality of predetermined provisional supply start timings when setting the supply start timing.
