Background
Conventionally, various techniques have been proposed for removing the adhering matter from the suction nozzle.
For example, an attached matter removing device described in patent document 1 below removes attached matter attached to a suction nozzle that includes a suction tube for sucking and holding an element by suction of air and a holding cylinder for holding the suction tube inside in a state in which a tip portion of the suction tube is projected, the suction tube and the holding cylinder being movable relative to each other, the attached matter removing device including: a cylindrical housing; a first gas blowing device for blowing gas into the suction pipe of the suction nozzle held by the holder; a second gas blowing device that blows gas into the casing; and an abutting portion provided in the housing and configured to abut against a suction pipe of the suction nozzle, wherein the suction pipe is moved to the outside of the holding cylinder by blowing gas into the suction pipe by the first gas blowing device, the suction pipe of the suction nozzle held by the holder is moved to the inside of the holding cylinder by abutting against the abutting portion, and the adhering matter adhering to the suction nozzle is removed by blowing gas into the housing by the second gas blowing device in a state where the suction nozzle held by the holder is moved to the inside of the housing.
In this way, in the attached matter removing device described in patent document 1, gas is blown to the nozzle held by the holder. When the gas is blown to the suction nozzle, the suction pipe and the holding cylinder are moved relative to each other by the abutment of the suction pipe against the abutting portion and the blowing of the gas by the first gas blowing device. That is, the pipette advances and retreats inside the holding cylinder. This makes it possible to remove the adhering substances by blowing the gas while advancing and retreating the suction pipe holding cylinder. This enables the adhering matter between the straw and the holding cylinder to be appropriately removed.

Detailed Description
Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
Fig. 1 shows an electronic component mounting apparatus 10. First, the structure of the electronic component mounting apparatus 10 will be described. The electronic component mounting apparatus 10 includes one system base 12 and two electronic component mounting machines (hereinafter, sometimes simply referred to as "mounting machines") 14 adjacent to each other on the system base 12. The parallel direction of the mounting machines 14 is referred to as the X-axis direction, and the horizontal direction perpendicular to the X-axis direction is referred to as the Y-axis direction.
Each mounting machine 14 mainly includes: a mounting machine body 20, a conveying device 22, a head moving device (hereinafter, sometimes simply referred to as a moving device) 24, a mounting head 26, a supply device 28, and a nozzle station 30. The mounting machine body 20 includes a frame portion 32 and a beam portion 34 that is mounted on the frame portion 32.
The conveyor 22 includes two conveyor devices 40 and 42. The two conveyor devices 40 and 42 are disposed on the frame portion 32 so as to be parallel to each other and extend in the X-axis direction. The two conveyor devices 40 and 42 convey the circuit boards supported by the conveyor devices 40 and 42 along the X-axis direction by electromagnetic motors (not shown). The circuit board is held at a predetermined position by a board holding device (not shown).
The moving device 24 is an XY robot type moving device. The moving device 24 includes an electromagnetic motor (not shown) that slides the slider 50 in the X-axis direction and an electromagnetic motor (not shown) that slides the slider 50 in the Y-axis direction. A mounting head 26 is attached to the slider 50, and the mounting head 26 is moved to an arbitrary position on the frame portion 32 by the operation of the two electromagnetic motors.
The mounting head 26 mounts electronic components to the circuit substrate. A suction nozzle 60 is provided on the lower end surface of the mounting head 26. As shown in fig. 2, the suction nozzle 60 is composed of a main body cylinder 64, a flange 66, a suction pipe 68, and a locking pin 70. The main body cylinder 64 is cylindrical, and the flange portion 66 is fixed so as to extend to the outer peripheral surface of the main body cylinder 64. The suction pipe 68 is formed in a thin tubular shape, and is held in the main body cylinder 64 so as to be movable in the axial direction while extending downward from the lower end portion of the main body cylinder 64. The catch pin 70 is provided at the upper end of the main body cylinder 64 so as to extend in the radial direction of the main body cylinder 64. The suction nozzle 60 is attached to the mounting head 26 by a single operation so as to be attachable and detachable by a catch pin 70. The illustration of the engagement pin 70 is omitted in fig. 5, 6, and 13 to 15 described later. The mounting head 26 incorporates a spring (not shown) that applies an elastic force to the suction pipe 68 of the suction nozzle 60 attached to the mounting head 26. Thus, the suction pipe 68 is biased in a direction extending downward from the lower end of the body tube 64 by the elastic force of the spring incorporated in the mounting head 26. Further, a 2D code 74 is marked on the upper surface of the flange portion 66. The 2D code 74 shows, as individual information, an ID (identification) of the nozzle 60, a blowing manner of air (for example, a blowing direction of air, a blowing time of air, and the number of repetitions of air blowing) to be described later, and the like. Instead of the 2D code 74, a two-dimensional code or an RF tag may be marked on the upper surface of the flange portion 66. However, when the RF tag is marked on the upper surface of the flange portion 66, a reader for acquiring individual information from the RF tag is attached to a transfer head (see fig. 4)120 of a nozzle management device (see fig. 3)80, which will be described later.
The suction nozzle 60 is connected to a positive/negative pressure supply device (not shown) via a negative pressure air/positive pressure air passage. The suction nozzle 60 sucks and holds the electronic component by negative pressure, and separates the held electronic component by positive pressure. The mounting head 26 has a nozzle lifting device (not shown) for lifting and lowering the nozzles 60. By this nozzle elevating device, the mounting head 26 changes the position of the held electronic component in the vertical direction.
The supply device 28 is a feeder type supply device, and as shown in fig. 1, includes a plurality of tape feeders 72. The tape feeder 72 stores the braid elements in a wound state. The braid element is obtained by braiding electronic components. The tape feeder 72 feeds out the braid elements by a feeding device (not shown). Thereby, the feeder-type supply device 28 supplies the electronic components at the supply position by the feeding out of the braid component.
The nozzle station 30 has a nozzle tray 76. A plurality of suction nozzles 60 are housed in the suction nozzle tray 76. In the nozzle station 30, replacement of the nozzles 60 mounted on the mounting head 26 and the nozzles 60 accommodated in the nozzle tray 76 is performed as necessary. The nozzle tray 76 is detachable from the nozzle station 30, and the nozzles 60 stored in the nozzle tray 76 can be collected and the nozzles 60 can be replenished to the nozzle tray 76 outside the mounting machine 14.
Next, the mounting operation of the mounting machine 14 will be described. In the mounting machine 14, with the above configuration, the mounting head 26 can perform mounting work on the circuit board held by the transport device 22. Specifically, the circuit board is conveyed to the working position by a command from a control device (not shown) of the mounting machine 14, and is held by the board holding device at the working position. The tape feeder 72 sends out the tape elements by a command from the control device, and supplies the electronic elements at the supply position. The mounting head 26 moves above the supply position of the electronic component, and the electronic component is sucked and held by the suction nozzle 60. Next, the mounting head 26 moves above the circuit board, and mounts the held electronic component on the circuit board.
In the mounting machine 14, as described above, the electronic component supplied from the tape feeder 72 is sucked and held by the suction nozzle 60, and is mounted on the circuit board. Therefore, when a defect occurs in the suction nozzle 60, the mounting work may not be performed properly, and therefore, it is necessary to properly manage the suction nozzle 60. Then, the management of the nozzles 60 is performed by a nozzle management device described below.
Next, the structure of the nozzle management device will be described. As shown in fig. 3, the nozzle management device 80 has a substantially rectangular parallelepiped shape, and a door 82 for accommodating the nozzle tray 76 in the nozzle management device 80 or taking out the nozzle tray 76 from the nozzle management device 80 is provided on the front surface. A touch panel 86 and the like for displaying various information and performing various operations are disposed above the door 82.
As shown in fig. 4, the nozzle management device 80 includes: a management apparatus main body 90, a pallet storage apparatus 92, a nozzle transfer apparatus 94, a nozzle inspection apparatus 96, a nozzle cleaning apparatus 98, and a nozzle drying apparatus 100. In addition, fig. 4 is a perspective view showing a state where the housing parts of the nozzle management device 80 are detached, showing the internal configuration of the nozzle management device 80. Further, the control device 200 is connected to the nozzle management device 80. The control device 200 includes a flash memory 204. The detailed description of the control device 200 will be described later.
The management device body 90 includes a frame portion 102 and a beam portion 104 that is bridged on the frame portion 102. The frame portion 102 has a hollow structure, the pallet storage device 92 is disposed in the frame portion 102, and an upper end portion of the pallet storage device 92 is exposed to an upper surface of the frame portion 102.
The pallet receiving means 92 comprises a plurality of pallet carriers 106 and support arms 108. The tray placement rack 106 is a rack for placing the nozzle trays 110, and a plurality of tray placement racks 106 are arranged in parallel in the vertical direction inside the frame portion 102. In addition, the nozzle tray 110 accommodates a plurality of nozzles 60. The support arm 108 moves in the vertical direction in front of the plurality of pallet loading shelves 106 by operation of an arm moving device (not shown) and moves closer to and farther from the pallet loading shelves 106. Thus, the support arms 108 support the nozzle palette 110 in the palette carrier 106 and the nozzle palette 110 out of the palette carrier 106. The nozzle tray 110 taken out from the tray placement rack 106 is moved upward by the support arms 108 and moved toward the upper surface side of the frame portion 102.
The nozzle transfer device 94 is a device for transferring the nozzles 60 between the nozzle tray 76 and the nozzle palette 110, and is disposed on the beam portion 104. The nozzle transfer device 94 includes a transfer head 120 and a head moving device 122. A downward camera 126, a holding chuck 128 for holding the suction nozzle 60, and an air supply device 130 are attached to the lower end surface of the transfer head 120.
As shown in fig. 5, the holding collet 128 has two holding claws 132, holds the suction nozzle 60 at the body cylinder 64 by approaching the two holding claws 132, and disengages the held suction nozzle 60 by distancing the two holding claws 132. Further, an air flow path 136 is formed in the body portion 134 of the holding collet 128. The lower end of the air flow path 136 opens between the two holding claws 132, and the upper end is connected to the air supply device 130. Therefore, in a state where the holding chuck 128 holds the suction nozzle 60, air is supplied to the air flow path 136 by the air supply device 130, and the air is blown out from the lower end portion of the air flow path 136 into the suction nozzle 60. Thereby, air is blown into the suction nozzle 60 and blown out from the tip of the suction pipe 68. The holding chuck 128 also has a rotation device (see fig. 7)138 for rotating itself. Thereby, the suction nozzle 60 held by the holding chuck 128 is rotated. In addition, in fig. 5, the direction of reference sign D indicates the up-down direction. This point is also the same in fig. 6, 8, and 12 to 15 described later.
As shown in fig. 4, the head transfer device 122 is an XYZ-type transfer device that moves the transfer head 120 in the front-back direction, the left-right direction, and the up-down direction on the frame portion 102. Further, a fixing stand 131 for installing the nozzle tray 76 is provided on the upper surface of the front side of the frame portion 102, and the nozzles 60 are transferred between the nozzle tray 76 installed on the fixing stand 131 and the nozzle palette 110 supported by the support arms 108 of the palette storage device 92.
The suction nozzle inspection device 96 includes: camera 140, load sensor 142, and joint 146. The camera 140 is disposed on the upper surface of the frame portion 102 in an upward state, and the front end portion of the suction nozzle 60 is inspected using the camera 140. Specifically, the suction nozzle 60 to be inspected is held by the holding chuck 128, and the camera 140 photographs the suction nozzle 60 held by the holding chuck 128 from below. Thereby, the imaging data of the tip portion of the nozzle 60 is obtained, and the state of the tip portion of the nozzle 60 is checked based on the imaging data.
The load sensor 142 is disposed near the camera 140, and the load sensor 142 is used to check the expansion/contraction state of the tip of the suction nozzle 60. Specifically, the suction nozzle 60 to be inspected is held by the holding chuck 128, and the tip of the suction nozzle 60 held by the holding chuck 128 is brought into contact with the load sensor 142. The tip of the suction nozzle 60 is expandable and contractible, and the expansion and contraction state of the tip of the suction nozzle 60 is checked based on the load measured by the load sensor 142.
The joint 146 is disposed on the lower surface of the air supply device 130, and air is supplied from the air supply device 130. Then, the air flow rate of the suction nozzle 60 is checked by using the air supplied from the air supply device 130 to the joint 146. Specifically, the joint 146 is moved above the suction nozzles 60 placed on a cleaning blade 158, which will be described later, by the operation of the head moving device 122. The joint 146 is connected to the nozzle 60 to be inspected, and air is supplied from the air supply device 130. At this time, the air pressure is measured, and the air flow rate of the nozzle 60 is checked based on the air pressure.
Further, a plurality of waste boxes 148 are arranged on the upper surface of the frame portion 102, and the suction nozzles 60 determined to be defective suction nozzles by the above-described inspection are discarded to the waste boxes 148. Further, the nozzles 60 of the nozzles determined to be normal by the above-described inspection are returned to the nozzle tray 76 or the nozzle palette 110.
The nozzle cleaning device 98 is a device for cleaning and drying the nozzles 60, and is disposed near the pallet storage device 92. The nozzle cleaning device 98 includes a cleaning/drying mechanism 150 and a cleaning blade moving mechanism 152. The cleaning/drying mechanism 150 is a mechanism for cleaning and drying the suction nozzle 60 inside. The cleaning blade moving mechanism 152 is a mechanism for moving the cleaning blade 158 between an exposure position (a position where the cleaning blade 158 is shown in fig. 4) where the cleaning blade 158 is exposed and the inside of the cleaning/drying mechanism 150.
The nozzle drying device 100 is a device that dries the nozzles 60, and is disposed near the cleaning blade 158 located at the exposed position. As shown in fig. 5, the nozzle drying device 100 includes: a housing 160, a first air blower 164 and a second air blower 166. The case 160 has a substantially bottomed cylindrical shape.
The first air blowing device 164 is a device that blows air toward the inside of the casing 160. Specifically, two through holes 170 and 172 are formed in the side wall of the housing 160. The first through hole 170 penetrates the side wall of the housing 160 so as to extend in the radial direction of the housing 160. The first through hole 170 penetrates obliquely upward from the outer wall surface of the housing 160 toward the inner wall surface. On the other hand, the second through hole 172 penetrates the side wall of the housing 160 above the first through hole 170 so as to extend in the radial direction and the horizontal direction of the housing 160. The first air blower 164 is connected to the first through hole 170 and the second through hole 172 via pipes 176 and 178. Thereby, the first air blower 164 blows air into the casing 160 through the through holes 170 and 172. The second air blowing device 166 is a device that blows air toward the inside of the casing 160. Specifically, one through hole 180 is formed in the center of the bottom wall of the housing 160. The second air blower 166 is connected to the through hole 180 via a pipe 182. Thereby, the second air blower 166 blows air into the casing 160 through the through hole 180.
Next, the cleaning and drying of the suction nozzle 60 will be described. When the nozzles 60 are cleaned by the nozzle cleaning device 98, the nozzles 60 to be cleaned are transferred from the nozzle tray 76 or the nozzle palette 110 to the cleaning palette 158 by the nozzle transfer device 94. The cleaning blade 158 is moved into the cleaning/drying mechanism 150 by the operation of the cleaning blade moving mechanism 152, and the cleaning and drying of the suction nozzles 60 are performed in the cleaning/drying mechanism 150. After the cleaning and drying of the suction nozzles 60 by the cleaning and drying mechanism 150 is completed, the cleaning blade 158 is moved to the exposed position by the operation of the cleaning blade moving mechanism 152.
At this time, the suction nozzles 60 are dried to some extent, but in the cleaning and drying mechanism 150, the suction nozzles 60 are dried in a state of being mounted on the cleaning blade 158, and therefore, there is a possibility that moisture remains in the suction nozzles 60. In particular, in the suction nozzle 60, the main body cylinder 64 and the suction pipe 68 are relatively movable as described above, and water may enter between the main body cylinder 64 and the suction pipe 68, and therefore, the water entering between the main body cylinder 64 and the suction pipe 68 may remain. The suction nozzle 60 having the moisture remaining between the main body cylinder 64 and the suction pipe 68 may be determined as a defective suction nozzle in the inspection using the load sensor 142. Specifically, as described above, the inspection using the load sensor 142 is an inspection of the expansion/contraction state of the tip portion of the suction nozzle 60, and in the suction nozzle 60 in which moisture remains between the main body cylinder 64 and the suction pipe 68, the sliding resistance between the main body cylinder 64 and the suction pipe 68 increases due to the moisture, and the load measured by the load sensor 142 increases. Therefore, it is determined that the telescopic state of the tip portion of the suction nozzle 60 is not appropriate, and the suction nozzle 60 may be determined as a defective suction nozzle.
In view of such a situation, in the nozzle management device 80, after the cleaning and drying of the nozzles 60 by the cleaning and drying mechanism 150 is completed, the nozzles 60 are dried by using the nozzle drying device 100. Specifically, the suction nozzle 60 cleaned and dried by the cleaning and drying mechanism 150 is held by the holding chuck 128 from the cleaning blade 158. Then, the holding chuck 128 moves upward of the nozzle drying device 100 by the operation of the head moving device 122, and descends. Thus, as shown in fig. 5, the suction nozzle 60 held by the holding chuck 128 is inserted into the casing 160 of the nozzle drying device 100. The holding collet 128 is lowered to a position where the flange portion 66 of the suction nozzle 60 and the suction pipe 68 are positioned in the lateral direction of the through holes 170, 172. Thus, the suction nozzle 60 held by the holding chuck 128 is housed in the housing 160 in a state in which the suction pipe 68 is directed upward and downward.
Then, inside the housing 160, the suction nozzle 60 rotates, and air is blown out from at least one of the through holes 170, 172, 180 and the air flow path 136. That is, the holding collet 128 rotates by the operation of the rotation device 138, and thereby the suction nozzle 60 held by the holding collet 128 rotates. When the first air blower 164 is operated, air is blown out from the through holes 170 and 172 into the casing 160. Thereby, the air blown out from the lateral direction of the suction nozzle 60 is blown to the entire periphery of the rotating suction nozzle 60. When the air supply device 130 is operated, air is blown out from the air flow path 136 to between the two holding claws 132 of the holding collet 128 (that is, to the inside of the housing 160). Thereby, the air blown from above the suction nozzle 60 is blown toward the inside of the rotating suction nozzle 60. By such air blowing from above the suction nozzle 60 into the interior, the suction pipe 68 moves downward relative to the main body cylinder 64 and extends downward. Accordingly, the sliding surface of the suction pipe 68 with respect to the main body cylinder 64 is exposed on the lower side of the main body cylinder 64, and air is blown to the entire circumference of the sliding surface. On the other hand, when the second air blowing device 166 is operated, air is blown out from the through hole 180 into the casing 160. Thereby, the air blown out from below the suction nozzle 60 is blown toward the inside of the rotating suction nozzle 60. By such blowing of air from below the suction nozzle 60 to the inside, as shown in fig. 6, the suction pipe 68 moves upward relative to the main body cylinder 64 and extends upward. Thus, the suction pipe 68 is exposed to the sliding surface of the main body cylinder 64 on the upper side of the main body cylinder 64, and blows air over the entire circumference of the sliding surface. In this way, by blowing air from the lateral direction, the upper direction, or the lower direction of the suction nozzle 60 (particularly, the suction pipe 68) in a state inserted into the housing 160 and rotating the suction nozzle 60, moisture remaining between the main body cylinder 64 and the suction pipe 68 can be removed satisfactorily. The nozzle drying device 100 can remove deposits other than moisture, specifically, for example, oil, dust, an electronic component or a part thereof, solder, an adhesive, and the like. The first air blowing device 164, the air supply device 130, and the second air blowing device 166 may blow other gas, specifically, for example, a gas such as nitrogen gas, instead of the air.
Then, the nozzles 60 dried by the nozzle drying device 100 are returned to any one of the nozzle tray 76 and the nozzle palette 110 by the operation of the head moving device 122.
As shown in fig. 7, the nozzle management device 80 includes the control device 200. The control device 200 has a controller 202 and a plurality of drive circuits 206. The plurality of drive circuits 206 are connected to the pallet storage device 92, the nozzle inspection device 96, the nozzle cleaning device 98, the air supply device 130, the rotation device 138, the first air blowing device 164, and the second air blowing device 166. The controller 202 includes a CPU, ROM, RAM, and the like, and is mainly a computer and connected to the plurality of drive circuits 206. Thus, the operations of the pallet storage device 92, the nozzle transfer device 94, the nozzle drying device 100, and the like are controlled by the controller 202. Further, the controller 202 has: the alternate air blowing section 210, the synchronous air blowing section 212, the simultaneous air blowing section 214, and the modified air blowing section 216. The alternate air blowing section 210 is a functional section for alternately performing blowing of air based on the operation of the air supply device 130 and blowing of air based on the operation of the second air blowing device 166. The synchronized air blowing section 212 is a functional section for performing the blowing of air based on the operation of the first air blowing device 164 in synchronization with the blowing of air based on the operation of the second air blowing device 166. The simultaneous air blowing section 214 is a functional section for simultaneously performing blowing of air based on the operation of the air supply device 130, blowing of air based on the operation of the second air blowing device 166, and blowing of air based on the operation of the first air blowing device 164 at the time of starting the drying of the suction nozzle 60 or at the time of ending the drying of the suction nozzle 60. The changed air blowing unit 216 is a functional unit for changing the manner of blowing air to the suction pipes 68 of the suction nozzles 60 based on the individual information of the suction nozzles 60 acquired from the 2D code 74 by the camera 126. That is, the modified air blower 216 changes the time of operation, the order of operation, the combination of simultaneous operations, and the like according to the individual information indicated by the 2D codes 74 of the nozzles 60 with respect to the air supply device 130, the second air blower 166, or the first air blower 164.
Next, the discard box 148 will be described. As shown in fig. 8, (the body portion 134 of) the holding chuck 128 holding the suction nozzle 60 by the two holding claws 132 is moved upward of the waste bin 148 by the operation of the head moving device 122. Thereby, the suction nozzle 60 determined to be a defective suction nozzle by the above-described inspection is discarded to the discard box 148.
The disposal container 148 includes a frame 300 and a buffer material 302 such as sponge. The housing 300 is a case having an open upper surface. The cushion material 302 is disposed inside the housing 300, and includes an inclined surface 304 and a flat surface 306. On the descending side of the inclined surface 304, the inclined surface 304 is continuous with the flat surface 306.
The inclined surface 304 is entirely covered by a buffer member 308. The buffer member 308 uses a tape or a brush material. Accordingly, the suction nozzle 60 is dropped onto the inclined surface 304 via the buffer member 308, and thus can be rolled more strongly than when dropped directly onto the inclined surface 304. In addition, for example, a polytetrafluoroethylene tape or the like is present as the tape material. In addition, the brush material includes, for example, a bristle material of the static electricity removing brush.
A stepped portion 312 protruding upward from the inclined surface 304 is provided at an upper end portion 310 of the inclined surface 304. That is, the step portion 312 is formed of the cushioning material 302. The height H of the step 312 is set to be not less than the maximum length L from the flange 66 of the suction nozzle 60 to the tip of the suction pipe 68. Here, the maximum length L is a length from the flange portion 66 to the tip end of the suction pipe 68 when the suction pipe 68 is maximally projected from the lower end of the main body cylinder 64 (that is, the lower surface of the flange portion 66) in the suction nozzle 60.
Next, a control routine of the nozzle management method 220 will be described with reference to the flowchart of fig. 9. The control program shown in the flowchart of fig. 9 is stored in the flash memory 204 of the control device 200, and is executed by the CPU of the controller 202 when the operator performs a predetermined operation via the touch panel 86.
When the nozzle management method 220 is executed, the cleaning process S10 is first performed. In this process, the nozzle cleaning device 98 cleans and dries the nozzles 60 as described above.
Next, the flow rate check processing S12 is performed. In this process, the nozzle check device 96 performs the air flow rate check of the nozzles 60 as described above. The suction nozzles 60 determined to be defective suction nozzles (that is, defective) in this inspection are held by the holding chuck 128 from the cleaning blade 158 and discarded in the discard box 148 in the same manner as in the recovery process S30 described later.
Subsequently, a drying process S14 is performed. In this process, the nozzle drying device 100 dries the nozzles 60 as described above. In addition, in order to dry the suction nozzles 60, while the suction nozzles 60 on the cleaning blade 158 are held by the holding chucks 128 of the transfer head 120, the 2D codes 74 of the suction nozzles 60 are photographed by the camera 126 of the transfer head 120. Thereby, the individual information of the suction nozzle 60 indicated by the 2D code 74 is acquired. Further, the drying of the nozzles 60 is performed by the alternate air blowing unit 210, the synchronized air blowing unit 212, the simultaneous air blowing unit 214, or the changed air blowing unit 216 functioning in accordance with the acquired individual information. The nozzle 60 may be dried so that the upper surface of the flange 66 of the nozzle 60 is dried first.
Next, the load check processing S16 is performed. In this process, the nozzle inspection device 96 performs the inspection using the load sensor 142 as described above. Then, the first determination process S18 is performed. In this process, in the inspection using the load sensor 142, it is determined whether or not the suction nozzle 60 as an inspection target is a normal suction nozzle (that is, a pass).
When the nozzle 60 as the inspection object is a defective nozzle (that is, a defective nozzle) (S18: no), the second determination process S20 is performed. In this process, regarding the inspection using the load sensor 142, it is determined whether the number of failures of the suction nozzle 60 as an inspection target is N +1 times. Here, N is a predetermined number of times and is stored in the flash memory 204. The predetermined number of times N can be changed by the operator operating the touch panel 86 before the nozzle management method 220 is executed.
When the number of failures of the nozzle 60 to be inspected is not N +1 (S20: no), the drying process S14, the load inspection process S16, and the first determination process S18 are repeated for the nozzle 60 held by the holding chuck 128.
On the other hand, when the nozzle 60 to be inspected is a normal nozzle (that is, a good nozzle) (S18: yes), the image inspection process S22 is performed with respect to the nozzle 60 held by the holding chuck 128. In this process, the nozzle inspection device 96 performs the inspection using the camera 140 as described above. Then, the third determination process S24 is performed. In this process, in the inspection using the camera 140, it is determined whether the suction nozzle 60 as the inspection object is a normal suction nozzle (that is, a pass).
When the nozzle 60 as the inspection object is a normal nozzle (that is, qualified) (S24: yes), the storing process S26 is performed. In this process, the ID of the nozzle 60 held by the holding chuck 128 is stored in association with the number of times (hereinafter, referred to as the number of repetitions) the drying process S14 (the load check process S16 and the first determination process S18) is repeated.
Specifically, for example, as in the data table 208 shown in fig. 10, 2 of the number of repetitions is stored in association with 1001 of the ID of the nozzle 60, 1 of the number of repetitions is stored in association with 1002 of the ID of the nozzle 60, and 3 of the number of repetitions is stored in association with 1003 of the ID of the nozzle 60. In addition, a data table 208 is stored in the flash memory 204. In addition to the number of repetitions, the data table 208 may store the inspection results of the flow rate inspection process S12, the load inspection process S16, and the image inspection process S22 in association with the ID of the nozzle 60 held by the holding chuck 128.
Next, the fourth determination process S28 is performed. In this process, it is determined whether or not the drying by the nozzle drying device 100 has been completed for all the nozzles 60 mounted on the cleaning blade 158.
When the drying by the nozzle drying device 100 is not completed for all the nozzles 60 mounted on the cleaning blade 158 (no in S28), the nozzles 60 held by the holding chuck 128 are returned to the nozzle tray 76 or the nozzle blade 110, and then the nozzles 60 are held by the holding chuck 128 from the cleaning blade 158. The drying process S14 is performed on the suction nozzle 60 held by the holding chuck 128. When the drying by the nozzle drying device 100 has been completed for all the nozzles 60 mounted on the cleaning blade 158 (yes in S28), the nozzle management method 220 is completed.
On the other hand, when the number of consecutive failures of the inspection using the load cell 142 is N +1 (yes in S20) and when the inspection using the camera 140 is failed (no in S24), the collection process S30 is performed. As shown in fig. 11, the collection process S30 includes a movement process S32 and a separation process S34.
When the recovery process S30 is executed, the movement process S32 is executed first. In this process, (the body portion 134 of) the holding collet 128 holding (the body cylinder 64 of) the suction nozzle 60 by the two holding claws 132 is moved to above the waste box 148 by the operation of the head moving device 122, as shown in fig. 12. At this time, the suction pipe 68 of the suction nozzle 60 held by the holding chuck 128 is vertically oriented above the inclined surface 304 of the disposal box 148 (of the buffer 308), and at least a part of the flange portion 66 of the suction nozzle 60 is positioned above the step portion 312 of the disposal box 148. Therefore, the perpendicular line a extending from the end portion on the inclined surface 304 side at the step portion 312 of the waste box 148 intersects the flange portion 66 of the suction nozzle 60 held by the holding chuck 128.
Next, the detachment process S34 is performed. In this process, as shown in fig. 13, the suction nozzle 60 is disengaged from the holding collet 128 by the separation of the two holding claws 132. As a result, as shown in fig. 14, the suction nozzle 60 drops toward the waste box 148, and the flange portion 66 of the suction nozzle 60 comes into contact with the step portion 312 of the waste box 148. Therefore, as shown in fig. 15, after the orientation (of the suction pipe 68) of the suction nozzle 60 is changed, the suction nozzle falls and rolls on (the buffer member 308 of) the inclined surface 304 of the waste box 148, and is collected into the waste box 148. Then, the fourth determination process S28 is performed.
As described above, in the nozzle management device 80 and the nozzle management method 220 according to the present embodiment, the drying process S14 is performed to dry the nozzles 60. Here, when air is blown from below the suction nozzle 60 to the suction pipe 68 by the second air blowing device 166, the suction pipe 68 of the suction nozzle 60 moves upward inside the main body cylinder 64. On the other hand, when air is blown from above the suction nozzle 60 to the suction pipe 68 by the air supply device 130, the suction pipe 68 of the suction nozzle 60 moves downward inside the main body cylinder 64. In this way, the nozzle management device 80 and the nozzle management method 220 according to the present embodiment can dry the nozzles 60 while moving the suction pipes 68 of the nozzles 60 up and down by the blowing of the gas.
Incidentally, in the present embodiment, the lower end of the main body tube 64 is an example of one end of the main body tube. The 2D code 74 is an example of an identification medium. The nozzle management device 80 is an example of a nozzle management device. The camera 126 is an example of a reader. The retainer clip 128 is an example of a retainer. The air supply device 130 is an example of the first gas blowing device. The casing 160 is an example of the blowing cylinder. The first air blowing device 164 is an example of the third air blowing device. The second air blowing device 166 is an example of the second gas blowing device. The drying process S14 is an example of the blowing process. The controller 202 when performing the drying process S14 is an example of the control unit. The drying process S14 when the alternating air blower 210 functions is also an example of the blowing process. The drying process S14 when the synchronized air blower 212 functions is an example of the synchronization process. The drying process S14 when the simultaneous air blowing section 214 functions is an example of the simultaneous process. The drying process S14 when the changed air blowing unit 216 functions is an example of the change process. The drying process S14 is an example of the blowing step.
The present disclosure is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present disclosure.
For example, in the drying process S14, the blowing of the air by the operation of the air supply device 130 may be performed after the blowing of the air by the operation of the second air blowing device 166 is repeated a plurality of times. Similarly, the blowing of the air by the operation of the second air blowing device 166 may be performed after the blowing of the air by the operation of the air supply device 130 is repeated a plurality of times. In either case, the suction pipe 68 of the suction nozzle 60 can be surely moved up and down inside the main body cylinder 64 in the drying process S14.
In addition, as long as the suction pipes 68 of the suction nozzles 60 can be moved up and down inside the main body cylinder 64 by the blowing of the air by the operation of the air supply device 130 and the blowing of the air by the operation of the second air blowing device 166 in the drying process S14, the suction pipes 68 of the suction nozzles 60 may be in a state in which they are inclined from the vertical direction with respect to the posture of the suction nozzles 60 housed in the casing 160.
In the drying process S14, the suction nozzle 60 may not be housed in the casing 160 as long as the suction pipe 68 of the suction nozzle 60 can be moved up and down inside the main body cylinder 64 by blowing air by the operation of the air supply device 130 and blowing air by the operation of the second air blowing device 166.
Note that, the manner of blowing air (for example, the blowing direction of air, the blowing time of air, and the number of times of repetition of blowing of air) in the drying process S14 may be stored in the flash memory 204 or the like in advance in a state associated with the ID indicated by the 2D code 74 or the like, instead of being indicated by the 2D code 74 or the like.
