Detailed Description
An example of the embodiment of the present invention will be described below with reference to the attached drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals.
Fig. 1 is a schematic plan view of an example of the component sorting apparatus according to the present embodiment, as viewed from above, fig. 2 is a schematic plan view of a portion II of the component sorting apparatus shown in fig. 1, as enlarged, and fig. 3 is a schematic side view of the component sorting apparatus shown in fig. 1, as viewed from the side, as enlarged, and as a schematic side view of a portion II. In fig. 1 to 3, an XY orthogonal coordinate system is shown.
The component sorting apparatus 1 shown in fig. 1 to 3 is an apparatus for sorting qualified products while sequentially conveying a plurality of electronic components 3 and inspecting the components. The component sorting apparatus 1 includes a ball feeder 10, a linear feeder 20, a turntable 30, a cover 36, a plurality of photographing devices 40, a discharge mechanism 50, and an inspection sorting controller 70.
The electronic component 3 is a surface-mounted electronic component (also referred to as a chip component) such as a laminated ceramic capacitor. For example, as shown in fig. 8, the electronic component 3 includes: a laminate 3a in which a plurality of dielectric layers including a ceramic material and one or more conductor layers are laminated; and two external electrodes 3b disposed on both end surfaces of the laminate 3a, respectively. The laminate 3a, that is, the electronic component 3, has a rectangular parallelepiped shape, and has two main surfaces TS1 and TS2 facing each other in the lamination direction, two side surfaces WS1 and WS2 facing each other in the width direction intersecting the lamination direction, and two end surfaces LS1 and LS2 facing each other in the longitudinal direction intersecting the lamination direction and the width direction.
The size of the electronic component 3 is not particularly limited, but may be, for example, a size of 0.1mm or more and 3.2mm or less in the longitudinal direction, a size of 0.05mm or more and 1.6mm or less in the width direction, and a size of 0.05mm or more and 1.6mm or less in the lamination direction. In addition, these dimensions can vary by crossing.
The electronic component 3 is not limited to the above-described multilayer ceramic capacitor using dielectric ceramics, and may be various electronic components such as a piezoelectric component using piezoelectric ceramics, a thermistor using semiconductor ceramics, and an inductor using magnetic ceramics.
As shown in fig. 1 to 3, the ball feeder 10 aligns and conveys a plurality of electronic components 3 supplied from a hopper, for example. The hopper is a device for detecting a shortage of the number of electronic components 3 in the ball feeder 10, and automatically replenishing the ball feeder 10 with the electronic components 3 to maintain the number of electronic components 3 in the ball feeder 10 at a fixed amount.
The ball feeder 10 is provided with a vibration mechanism 12 that vibrates the ball feeder 10. The vibration mechanism 12 includes, for example, a piezoelectric element that generates vibration at a frequency corresponding to a voltage. The shape of the ball feeder 10 is a round shape. The ball feeder 10 is vibrated to move the electronic components 3 from the circular center portion to the outside, and the electronic components are spirally arranged and conveyed.
The linear feeder 20 sequentially linearly conveys the plurality of electronic components 3 which are arranged and conveyed by the ball feeder 10. The linear feeder 20 is provided with a vibration mechanism 22 that vibrates the linear feeder 20. The vibration mechanism 22 includes, for example, a piezoelectric element that generates vibration at a frequency corresponding to a voltage. The linear feeder 20 is preferably inclined with respect to the horizontal plane. The linear feeder 20 conveys the electronic parts 3 by vibration.
The linear feeder 20 preferably includes SUS or the like. As a result, the electronic component 3 can be charged when the electronic component 3 is conveyed by the vibration in the linear feeder 20.
The turntable 30 sequentially rotates and conveys the plurality of electronic components 3 conveyed by the linear feeder 20. As shown in fig. 1 and 2, the turntable 30 includes a guide mechanism 32 on the upstream side, and the electronic components 3 from the linear feeder 20 are guided to a rotary conveying path (rotary conveying path) 31 by the guide mechanism 32. The turntable 30 conveys the electronic component 3 along the rotary conveying path 31.
As shown in fig. 3, an electrostatic chuck 34 is preferably provided on the lower side of the turntable 30. This allows the electronic components 3 charged in the linear feeder 20 to be electrostatically attracted and transported.
The conveyance speed of the turntable 30 is faster than that of the linear feeder 20. As a result, as shown in fig. 2 and 3, the intervals between the electronic components 3 can be made free, and the appearance inspection of the end face side of the electronic components 3 can be performed.
The turntable 30 is made of a material such as glass or resin, and has transparency. This allows the appearance inspection of the back surface side of the electronic component 3.
As shown in fig. 1, a cover 36 for covering the electronic component 3 is disposed on the turntable 30. Details of the cover 36 will be described later.
As shown in fig. 1, the photographing apparatus 40 is, for example, a camera or an image sensor. Although not shown, a light source is provided near the camera. Along the rotary conveying path 31 of the turntable 30, 6 photographing apparatuses 40 are provided. The 6 photographing devices 40 photograph 6 outer surfaces, i.e., two main surfaces TS1 and TS2, two side surfaces WS1 and WS2, and two end surfaces LS1 and LS2, of the electronic component 3 on the turntable 30, respectively. Each of the photographing devices 40 may be provided with an illumination device such as annular illumination or dome illumination that irradiates the photographing surface of the electronic component 3.
As shown in fig. 1, the discharging mechanism 50 discharges the sorted acceptable products from the turntable 30 based on the result of the appearance inspection by the inspection sorting controller 70 described later, and stores the discharged acceptable products in a box or the like. The method of discharging the acceptable product by the discharging means 50 is not particularly limited, but examples thereof include air blowing, air suction, physical contact extrusion, and the like. For example, when the acceptable product is conveyed, the discharge mechanism 50 discharges the acceptable product from the turntable 30 and stores the acceptable product in a box or the like by blowing air to the acceptable product on the turntable 30 in accordance with a command from the inspection and sorting controller 70.
The inspection sorting controller 70 controls the entire component sorting apparatus 1. Specifically, the inspection sorting controller 70 performs appearance inspection of the electronic component 3 on the turntable 30 based on the photographing result from the photographing apparatus 40, and sorts the non-defective products and the non-defective products based on the result of the appearance inspection.
Further, the inspection and sorting controller 70 controls the discharge of the acceptable product by the discharge mechanism 50. For example, the inspection and sorting controller 70 calculates timing of discharging the acceptable product from the discharge mechanism 50 based on information such as the conveyance speed (or the rotational speed and the rotational conveyance path length or radius) of the turntable 30, the position of the photographing device 40 in the turntable 30, and the like, and instructs the discharge mechanism 50.
The inspection and sorting controller 70 is constituted by an arithmetic processor such as a PLC (Programmable Logic Controller ), a DSP (Digital Signal Processor, digital signal processor), an FPGA (Field-Programmable Gate Array, field programmable gate array), or the like. The various functions of the inspection sort controller 70 are realized by executing given software (program) stored in the storage section, for example. The various functions of the inspection sort controller 70 may be implemented by cooperation of hardware and software, or may be implemented by hardware (electronic circuit) alone.
The storage unit in the inspection sort controller 70 is, for example, a rewritable memory such as an EEPROM. The storage unit stores predetermined software (program) for executing various functions of the sorting controller. The storage unit stores various setting values input from the outside, for example. The various set values include a conveyance speed of the linear feeder 20, a conveyance speed (or a rotation speed and a rotation conveyance path length or radius) of the turntable 30, information on the position of the photographing device 40 and the position of the discharge mechanism 50, a criterion of passing/failing articles, and the like.
The cover 36 will be described in detail below. As shown in fig. 1, the cover 36 is disposed on the turntable 30 to cover the electronic component 3 that is rotationally conveyed on the turntable 30. More specifically, the cover 36 is configured to cover the rotational conveyance path 31 of the electronic component 3 on the turntable 30. The cover 36 has an arc shape along the rotary conveying path 31 on the turntable 30.
Fig. 4A is a cross-sectional view taken along line IV-IV of the component sorting apparatus shown in fig. 1, and fig. 5 is a cross-sectional view taken along line V-V of the component sorting apparatus shown in fig. 1. As shown in fig. 4A and 5, the cross-sectional shape of the cover 36 intersecting the rotary conveying path 31 on the turntable 30 is a circular arc shape. Thereby, as shown in fig. 4A, the cover 36 can have, for example, a surface perpendicular to the line of sight of the photographing apparatus 40 photographing the main surface of the electronic component 3. Further, as shown in fig. 5, the cover 36 may have a surface perpendicular to the line of sight of the photographing apparatus 40 photographing the side surface of the electronic part 3, for example. As described above, if the surface of the cover 36 is perpendicular to the line of sight of the imaging device 40, refraction due to the cover 36 can be reduced, and the main surface and the side surfaces of the electronic component 3 can be accurately imaged. The present invention is not limited to the arc shape, and is configured to include a shape having a surface perpendicular to the line of sight of the imaging device 40. In addition, a part of the cover may be formed in a lens shape so as to have an amplifying function.
In fig. 4A and 5, a surface of the cover 36 perpendicular to the line of sight of the photographing apparatus 40 may be thinner than other surfaces of the cover 36. This can further reduce refraction caused by the cover 36, and can more accurately capture the main surface and the side surfaces of the electronic component 3.
Fig. 6 is a VI-VI cross-sectional view of the component sorting apparatus shown in fig. 1. As shown in fig. 6, the cover 36 has a surface inclined in a direction along the rotary conveying path 31 on the turntable 30. Thereby, the cover 36 can have, for example, a surface perpendicular to the line of sight of the photographing device 40 photographing the end surface of the electronic component 3. As described above, if the surface of the cover 36 is perpendicular to the line of sight of the imaging device 40, refraction due to the cover 36 can be reduced, and the end surface of the electronic component 3 can be accurately imaged.
In fig. 6, a surface of the cover 36 perpendicular to the line of sight of the photographing apparatus 40 may also be thinner than other surfaces of the cover 36. This can further reduce refraction caused by the cover 36, and can more accurately capture the end face of the electronic component 3.
Further, as shown in fig. 4A and 5, the cover 36 is separated from the turntable 30. For example, as shown in fig. 1 and 4A, the cover 36 may be suspended and supported by a plurality of cover support members 37 arranged at equal intervals, and the cover support members 37 may include support columns or the like fixed to a fixing member (not shown). Alternatively, as shown in fig. 4B, the cover 36 may be suspended and supported by a plurality of cover support members 37, the cover support members 37 including support posts or the like fixed to the respective photographing apparatuses 40. Alternatively, as shown in fig. 4C, the cover 36 may be supported by a plurality of cover support members 37 arranged at equal intervals, the cover support members 37 including wheels or the like provided between the cover 36 and the turntable 30. Thereby, the turntable 30 can rotate without interfering with the cover 36. The separation distance of the cover 36 and the turntable 30 is smaller than the smallest dimension among the length, width, and thickness of the electronic component 3. This prevents electronic components of different types from being mixed into the cover 36, that is, the rotary conveyance path 31 on the turntable 30. Further, the electronic component 3 in conveyance can be prevented from coming off the cover 36, that is, the rotary conveyance path 31 on the turntable 30.
The cover 36 is made of a material such as glass or resin, and has light transmittance (e.g., transparency). Thereby, the photographing device 40 can photograph the electronic component 3 through the cover 36.
The cover 36 may be colored (for example, a color obtained by subjecting the cover to long wavelength modulation (red) or short wavelength modulation (blue). This allows light to be modulated, and the surface state of a member that cannot be detected by transparent light to be detected. Alternatively, the cover 36 may have a polarizing property. This makes it possible to detect the surface state of the member that cannot be detected under transparent light. The light modulation is not limited to the cover, and the light of the light source may be modulated.
As described above, the component sorting apparatus 1 according to the present embodiment includes: a transparent turntable 30 for rotationally conveying the electronic component 3; 6 photographing devices 40 photographing 6 outer surfaces of the electronic part 3 on the turntable 30, respectively; an inspection sorting controller 70 that performs appearance inspection of the electronic component 3 based on the photographing result from the photographing apparatus 40, and sorts the qualified products based on the result of the appearance inspection; and a discharge mechanism 50 that discharges the qualified products sorted by the inspection sorting controller 70 from the turntable 30. This makes it possible to perform appearance inspection while conveying a plurality of electronic components 3, and to sort the qualified products.
In such a component sorting apparatus, inspection and sorting of different types of electronic components may be performed for each manufacturing lot. For example, there are components having different characteristics even in the same size among surface-mounted electronic components. More specifically, there are components having different capacitances even in the same size in the laminated ceramic capacitor.
In the conventional component sorting apparatus, the turntable is opened in order to photograph the electronic components on the turntable by the photographing device. Therefore, the rotating conveyance path 31 on the turntable may be mixed with different kinds of electronic components. If electronic components of the same size and different characteristics are mixed in this way and discharged as a good product, the mixing of the components occurs.
In this regard, according to the component sorting apparatus 1 of the present embodiment, the cover 36 is disposed on the turntable 30, and the cover 36 covers the electronic components 3 that are rotationally conveyed on the turntable 30. This prevents electronic components of different types from being mixed into the cover 36, that is, the rotary conveyance path 31 on the turntable. Therefore, the precision of component sorting can be improved.
In the conventional component sorting apparatus in which the turntable is opened, the electronic components during conveyance may be separated from the rotary conveying path, and the electronic components of the previous batch may remain on the turntable. In such a case, if the type of the electronic component in the current lot is different from the type of the electronic component in the previous lot, there is a possibility that the electronic component in the current lot may be mixed with the electronic component in the previous lot having the different type. If electronic components of the same size and different characteristics are mixed in this way, the accuracy of sorting decreases even if the accuracy of appearance inspection is high.
In this regard, according to the component sorting apparatus of the present embodiment, the cover 36 is configured to cover the rotary conveying path 31 of the electronic component 3 on the turntable 30. This prevents the electronic component 3 being transported from coming off the cover 36, i.e., from the rotating transport path 31 on the turntable 30. Therefore, the precision of component sorting can be improved.
The embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments, and various modifications and variations are possible. In the above-described embodiment, the component sorting apparatus 1 (fig. 1) including one cover 36 continuous along the rotational conveyance path 31 of the electronic component 3 on the turntable 30 is exemplified. However, the present invention is not limited thereto, and the component sorting apparatus 1 may be provided with a plurality of covers 36 divided along the rotational conveyance path 31 of the electronic component 3 on the turntable 30 (fig. 7; in addition, the cover support member 37 described above is omitted in fig. 7). In this case, the separation interval of the adjacent covers 36 is preferably smaller than the smallest dimension among the length, width, and thickness of the electronic component 3. For example, it is preferably 0.02mm or less.
In the above-described embodiment, the component sorting apparatus 1 including the cover 36 is exemplified, and the cover 36 has the circular arc shape along the rotational conveyance path 31 on the turntable 30 so as to cover the rotational conveyance path 31 of the electronic component 3 on the turntable 30. However, the present invention is not limited to this, and the component sorting apparatus 1 may be provided with a cover 36 for covering the entire turntable 30, for example.
In the above-described embodiment, the component sorting apparatus 1 in which the cover 36 is interposed between the turntable 30 and the photographing device 40 is exemplified. However, the present invention is not limited to this, and the component sorting apparatus 1 may be configured such that the cover 36 also covers the photographing device 40, for example.
