Description

  The present invention relates to an electronic circuit component mounting machine, and in particular, eliminates dust in a mounting area of an electronic circuit component mounting machine that includes a tape feeder and mounts an electronic circuit component supplied from the tape feeder on a circuit board. The present invention relates to a possible dust removing device.

  An electronic circuit component mounting machine (hereinafter, unless otherwise required) that takes out an electronic circuit component (hereinafter abbreviated as “component” unless otherwise specified) from a carrier tape sent by a tape feeder by a suction nozzle. Although abbreviated as “mounting machine” is widely used, the mounting operation may be hindered by dust. For example, dust is clogged in the suction nozzle, and the suction of components is hindered, or dust adheres to the imaging device or the background forming plate provided in the suction nozzle, thereby hindering imaging.

Therefore, for example, in Patent Document 1 below, the mounting area of the mounting machine is made as close as possible to the closed space, air is sucked in from the upper opening by the intake fan, and discharged from the lower opening, thereby mounting the mounting area together with the air. It is described that dust inside is eliminated. In addition, in this mounting machine, it is also described that the carrier tape after removing the parts discharged from the feeder is discharged to the outside by a shooter.
Patent Document 2 below describes that air containing ions is blown to a component held by an adsorption nozzle, and air around the component is sucked by an air suction device to remove dust.

JP 2005-277212 A JP 2008-103405 A

  However, there is still room for improvement in the technology described in the above publication. For example, in the apparatus described in Patent Document 1, the apparatus cost is high in order to make the mounting work area as close as possible, or the apparatus cost is high because a relatively large capacity intake fan is required. In addition, there is a problem that energy consumption increases and driving noise increases. Further, in the apparatus described in Patent Document 2, an apparatus for generating air containing ions is required, which increases the cost of the apparatus, or it is necessary to pass the suction nozzle near the dust removing apparatus. Therefore, there is a problem that the efficiency of the mounting work is reduced. The present invention has been made with the above situation as a background to further improve the mounting machine.

  Then, according to the present invention, (a) by feeding a taped component in which electronic circuit components are accommodated in a number of accommodating recesses of the carrier tape, an inlet facing the tape feeder that sequentially supplies the electronic circuit components, and the opposite side A tape discharge duct for discharging the waste carrier tape after taking out the electronic circuit components discharged from the tape feeder, and (b) branching from an intermediate portion of the tape discharge duct between the inlet and the outlet. (C) an intake fan that is provided in the branch passage and sucks air in the tape discharge duct through the branch passage, and (c) an air that is provided in the branch passage and is sucked into the intake fan. Thus, a dust removing device with a tape discharging function including a filter for capturing dust mixed in can be obtained.

  In the mounting work area of the mounting machine, dust is likely to be generated particularly around the tape feeder. For example, a top cover tape is usually attached to the carrier tape in order to prevent parts from falling out of the receiving recess of the carrier tape, but this top cover tape is peeled off from the carrier tape. In addition, dust tends to be generated when the carrier tape slides in the tape feeder or the tape discharge duct. When the carrier tape is made of paper, dust is particularly likely to occur.

On the other hand, in the dust removing device with a tape discharge function configured as described above, an intake fan is provided in a branch passage branched from the middle of a tape discharge duct having an inlet facing the tape feeder and an outlet on the opposite side. The air is sucked from both the inlet side and the outlet side and sucked into the branch passage. Therefore, dust generated around the tape feeder and dust generated in the tape discharge duct are collected in the branch passage. The air flow rate in the portion downstream of the branch passage of the tape discharge duct is set to a size that does not hinder the movement of the carrier tape to the outlet side and the dust moves in the direction opposite to that of the carrier tape. Then, the dust generated in the downstream portion can also be collected in the branch passage. As described above, the air around the tape feeder is intensively sucked, so that the intake fan only needs a relatively small capacity. Further, it is not necessary to make the mounting work area as closed as possible.
In addition, since the dust collected in the branch passage is removed by the filter, it is prevented from being discharged to the outside of the mounting machine, and the working environment is also prevented from being deteriorated.

A plurality of types of mounting heads 68 are prepared and selectively attached to the second X-axis slide 76 according to the type of the circuit board 57 on which the components are mounted.

  In the component supply device 24, a plurality of feeders 58 holding different types of components are attached to the feeder support base 60 in a state where the component supply units are arranged along the X-axis direction. As shown in FIG. 3, the component 90 is held by a carrier tape 96 having a large number of component receiving recesses 92 and feed holes 94 each formed at a constant pitch. The carrier tape 96 is formed by attaching a bottom cover tape to a portion where the through holes for the component receiving recesses 92 are arranged on the back surface of the paper tape in which the through holes for the component receiving recesses 92 and the feed holes 94 are formed. After the component 90 is accommodated in the component accommodating recess 92, the top cover tape 98 is affixed to the portion where the through holes for the component accommodating recess 92 are arranged on the surface of the paper tape, thereby preventing the component from falling off. This state is referred to as a taped component 100.

  At the time of taking out the component 90, as shown in FIG. 3, while the taped component 100 is covered with the cover 106 of the feeder 58, the component 90 is fed by the forming pitch of the component receiving recess 92 by a feeding device (not shown), The top cover tape 98 is peeled off by a peeling device (not shown) and taken out by the suction nozzle 80 from the component receiving recesses 92 that are sequentially opened. The waste carrier tape 108 after the component 90 is taken out is discharged to the outside of the mounting module 10 by the tape discharge duct 110 shown in FIGS. The waste carrier tape 108 is cut into a predetermined length by the tape cutter 111 (see FIG. 6) in the tape discharge duct 110 and stored in the tape storage box 112.

  A bottom view of the suction nozzle 80 is shown in FIG. 4. An air suction hole 114 is opened on the bottom surface to form a suction surface 116 that sucks the component 90, and a background forming plate 118 is provided above the suction surface 116. It has been. The background forming plate 118 forms a bright or dark background when the component 90 adsorbed on the adsorption surface 116 is imaged by the component imaging device 30. Dust is sucked into the air suction hole 114 of the suction nozzle 80 and clogs and adversely affects the suction of the component 90, or dust adheres to the background forming plate 118, and processing of image data acquired by imaging the component 90 May be adversely affected.

  One important source of the dust is the taped component 100. As described above, when the taped component 100 is fed by the feeder 58, the top cover tape 98 is peeled off from the carrier tape 96, the carrier tape 96 is discharged by the tape discharge duct 110, and is cut by the tape cutter 111. Dust is generated.

For this reason, the mounting module 10 is provided with a dust removing device 130 shown in FIGS. The dust removing device 130 is configured using the tape discharge duct 110 and is a dust removing device with a tape discharging function.
As shown in FIG. 5, the feeder support base 60 includes a first part 132 that directly supports the feeder 58 from below, and a second part 134 that supports the first part 132 from below. The second part 134 is formed by a part of the bed 36 of the module main body 18, and although not shown, a part of the electric control device 32 is accommodated therein. The first part 132 supports a plurality of feeders 58 arranged in a direction parallel to the X-axis direction. The first part 132 faces the end of the plurality of feeders 58 on the side close to the substrate transfer device 20 and discharges the tape. An inlet 136 of the duct 110 is formed, and an outlet 138 is formed facing the tape storage box 112.

  The tape discharge duct 110 is composed of three members, a first member 140, a second member 142, and a third member 144. The first member 140 is located forward from the inlet 136 and the lower part. And a curved portion that smoothly connects both the portions, and the third member is inclined so that the whole lower portion is located forward. The second member 142 is provided between the first member 140 and the third member 144, and the second member 142 and the third member 144 cooperate with each other, and the feeder support base 60 of the tape discharge duct 110. The part which penetrates the inside is constituted. A shear type tape cutter 111 driven by an actuator 146 is provided inside the second member 142, and the waste carrier tape 108 is cut into a predetermined length and stored in the tape storage box 112. The first member 140 and the third member 144 are fixed to the module main body 18, but the second member 142 is movable in a direction parallel to the X-axis direction by the guide 150 shown in FIG. Yes.

  The two side walls (see FIG. 6) facing each other in the X-axis direction of the second member 142 have a plurality of through holes 160 formed as perforated plate portions 162 as shown in FIG. The perforated plate portion 162 has a quadrilateral shape (a trapezoidal shape in the illustrated example), and the filter receiving portions 164 and 166 each have a groove shape at positions corresponding to three sides including two parallel sides of the quadrilateral. 168 are provided. Further, as shown in FIG. 5, the filter 170 is disposed so as to cover the perforated plate portion 162 from the outside. As shown in FIG. 8, the filter 170 has frame members (for example, paper) 174, 176 attached to the outer periphery of a filter element (for example, a plurality of non-woven fabrics stacked) 172, The frame member 174 is detachably attached to the second member 142 in a state where the frame member 174 is received by the filter receiving portions 164 and 166 and the frame member 176 is received by the filter receiving portion 168. In other words, the surface of the filter 170 on the tape discharge duct 110 side is covered with the perforated plate portion 162, and the size of the through hole 160 of the perforated plate portion 162 (since it is circular in the illustrated example). The diameter) is selected so that the waste carrier tape 108 is not caught, so that the waste carrier tape 108 is not caught by the perforated plate portion 162 or the filter 170. Further, since the perforated plate portion 162 and the filter 170 are not disposed in the tape discharge duct 110, it is of course possible to prevent the movement of the waste carrier tape 108 in the tape discharge duct 110.

  As shown in FIG. 6, a maintenance hole 180 that enables inspection and attachment / detachment of the filter 170, and the tape discharge duct 110, as shown in FIG. A maintenance hole 182 that allows the second member to be pulled out is formed, but both are closed by the covers 184 and 186 that are closing members, and other openings are closed as much as possible. The internal space of the housing 178 is closed as much as possible. An exhaust fan 190 is attached to an opening formed in the bottom wall of the housing 178 so that air in the internal space of the housing 178 is discharged to the outside.

  If the exhaust fan 190 discharges the air in the internal space of the housing 178 to the outside, the pressure in the internal space becomes lower than the atmospheric pressure, so that the air in the tape discharge duct 110 flows into the internal space of the housing 178. Air is sucked from the inlet 136 and the outlet 138, and air flows from the inlet 136 and the outlet 138 toward the second member. In other words, the internal space of the housing 178 forms a branch passage 194 branched from the middle of the main passage 192 from the inlet 136 to the outlet 138 in the tape discharge duct 110, and the passages 192 and 194 have FIG. , 6 generates an air flow indicated by a two-dot chain line arrow. Along with this air flow, dust generated in each of the above-described parts is sucked toward the second member 142. However, as described above, the filter 170 is provided at the branch part of the branch path 194 from the main path 192. , Dust is captured by the filter 170, and only air is discharged to the outside of the housing 178 through the branch passage 194. After all, in the dust removing device 130, the exhaust fan 190 functions as an intake fan that sucks the air around the feeder 58, particularly the air around the feeder 58, with the dust. At the same time, the exhaust fan 190 also functions as an exhaust fan that discharges the air heated by the electric control device 32 that generates heat in the internal space of the housing 178 to the outside of the housing 178.

  As described above, air is sucked from the middle of the tape discharge duct 110 to the branch passage 194 side. However, the second member 142 has a larger cross-sectional area than the first member 140 and the third member 144. Since the air is sucked from the position deviated laterally from the moving path of the waste carrier tape 108, the air flow velocity in the entire inlet 136 is relatively uniform, and the air in the vicinity of the plurality of feeders 58 is relatively even with dust. Sucked into. In the second member 142, dust having a small mass relative to the surface area is easily sucked into the branch passage 194 side along with the air while changing the moving direction, while the waste carrier tape 108 having a large mass relative to the surface area is sucked. The movement direction does not change easily, and the movement continues stably in the main passage 192 toward the outlet 138. Dust and waste carrier tape 108 are well separated. The wind guide tube 196 (see FIG. 6) provided in the second member 142 promotes this tendency. The tape cutter 111 is provided in the vicinity of the outlet of the air guide tube 196.

  In the present embodiment, the exhaust fan 190 serves as both the exhaust fan that discharges the warmed air in the housing 178 and the intake fan of the dust removing device 130, but it can also be dedicated to intake. is there. For example, as shown in FIG. 9, a dedicated intake duct 200 formed separately from the housing 178 is connected in the middle of the tape discharge duct 202 to form a branch passage, and an intake fan 204 is provided in the dedicated intake duct 200. . Even in that case, it is desirable to provide the perforated plate portion 206 at the branching portion of the tape discharge duct 202 to the intake-only duct 200, but the filter 208 may be provided anywhere downstream from the branching portion. It can also be provided downstream of the intake fan 204. However, from the viewpoint of preventing dust from adhering to the intake fan 204 and making cleaning difficult, it is desirable that it be provided on the upstream side of the intake fan 204 so that it can be inserted and removed as shown in the figure.
