Description

Technical Field

[0001] The present invention relates to a device and a method, and in particular to an electronic component identification device and an electronic component identification method. Background Art

[0002] In order to mount electronic components on a circuit board, it is particularly important to know the position of the electronic components. In this case, various methods can be used to identify the electronic components. In particular, the position of the electronic components can be known by directly shining light on the electronic components and capturing the reflected image or shadow.

[0003] In this case, in order to obtain a clear image of the electronic component, light should be irradiated to the electronic component from multiple directions. In this case, multiple light generating devices are provided so that light can be supplied to the electronic component from multiple directions of the electronic component.

[0004] However, as in the above case, it may be difficult to obtain a clear image due to interference between multiple light generating devices or their positions. In particular, when the electronic component has leads, it may be necessary to calibrate the light generating device and the leads because it is necessary to accurately irradiate the light to the leads.

[0005] Such an apparatus for identifying electronic components is disclosed in detail in Korean Patent Publication No. 1999-0086163 (Title of Invention: Acquisition Effect Inspection Apparatus Using Multiple Illumination).

[0045] Reference Figures 1 to 5 The electronic component identification device 100 may include a light source unit 110 , a reflection unit 120 , a photographing unit 130 and a body unit 140 .

[0046] The light source unit 110 may generate light and may provide linear light to the outside. The light source unit 110 may include a light generating unit 111, a light diffusion unit 112, and a light source body unit 113. The light generating unit 111 may include a laser diode and may provide linear light to the outside. The light diffusion unit 112 may diffuse the light generated from the light generating unit 111. At this time, the light diffusion unit 112 may be formed as a whole with the light generating unit 111, or may be configured to be separated from the light generating unit 111. The light diffusion unit 112 may be formed in various shapes. For example, the light diffusion unit 112 may include a diffractive optical element (DOE). Furthermore, the light diffusion unit 112 may be perpendicular to the path of the light (for example, Figure 1The light source body 113 is configured in the X direction, and the cross section may include a circular or elliptical lens. In the following, for the sake of convenience, the light diffusion part 112 is described in detail mainly based on the case where it includes a diffractive optical element. The light source body 113 accommodates the light generating part 111 and the light diffusion part 112 inside, and can fix the light generating part 111 and the light diffusion part 112 to the reflecting part 120. At this time, bolts that can adjust the position of the light diffusion part 112 are arranged on the light source body 113 in a way that contacts the light diffusion part 112.

[0047] The reflective part 120 is connected to the light source part 110 to reflect the light supplied from the light source part 110. At this time, the reflective part 120 can infinitely repeat the light to form a surface where the light overlaps each other. Such a reflective part 120 may include a reflective housing 121 and a reflective plate 122. The reflective housing 121 may be formed with an insertion hole or an insertion groove to insert the light source part 110. As another embodiment, the reflective housing 121 may also include other structures that guide the light emitted from the light source part 110. And, the reflective housing 121 may be formed as a closed loop. At this time, the reflective housing 121 may include an opening 123 inside. The shape of such an opening 123 may be various. For example, the shape of the opening 123 may include a circle, an ellipse or a polygon. In the following, for the convenience of explanation, the case where the opening 123 is a quadrangle is mainly described in detail. The emitting plate 122 may be in the form of a mirror. For example, the reflective plate 122 may include metal, plastic, etc. that has been subjected to mirror treatment. As another embodiment, the reflective plate 122 may include glass with a mirror surface. At this time, the reflector 122 is not limited to the above content, and can include all materials and all forms that can reflect the light supplied from the outside. In the following, for the convenience of explanation, the case where the reflector 122 includes a mirror is mainly described in detail. The reflector 122 as described above does not need to be configured at the portion of the reflective shell 121 where the light supplied from the light source unit is incident, but is configured at other portions of the reflective shell 121 other than the above. In this case, the reflector 122 is not completely connected to each other, but can be configured in a partially cut form. As another embodiment, the portion of the reflector 122 where the light emitted from the light source unit 110 is incident may include a component that reflects the incident light while transmitting the light supplied from the light source unit 110. In this case, the reflector 122 may include a half-reflector, and the half-reflector may be configured at the portion of the reflective shell 121 where the light from the light source unit 111 is incident on the opening 123 side. In the following, for the convenience of explanation, the case where the reflector 122 is not configured at the portion where the light is incident on the opening 123 is mainly described in detail.

[0048] The photographing unit 130 may be arranged to face the head 10. In this case, the photographing unit 130 may include a lens and an image sensor.

[0049] The main body 140 can connect the shooting part 130 with the light source part 110 and the reflection part 120. At this time, a space can be formed inside the main body 140, and light can be prevented from being incident from the outside. That is, the main body 140 can be formed in a dark box shape. Such a main body may include a main body 141 having a space formed inside and a partition 142 arranged on the main body 141. At this time, the partition 142 can divide the internal space of the main body 141. In particular, the partition 142 can completely separate the internal space of the main body 141. In this case, the light source part 110, the reflection part 120 and the shooting part 130 can be respectively equipped in plurality. At this time, each light source part 110, each reflection part 120 and each shooting part 130 can be arranged corresponding to each other, and one light source part 110, one reflection part 120 and one shooting part 130 arranged corresponding to each other can be arranged in a space divided by the partition 140. As described above, when the light source units 110, the reflective units 120, and the imaging units 130 are arranged corresponding to each other, the partitions 142 are disposed between the adjacent light source units 110, the reflective units 120, and the imaging units 130, so that the imaging units 130 can obtain an image without or with reduced noise. In particular, in this case, the main body 140 may also be provided with an additional lighting unit (not shown).

[0050] In addition, the electronic component identification device 100 as described above can be configured in a variety of devices for use. For example, when an electronic component P such as a semiconductor chip or a capacitor is transferred and arranged on a circuit substrate PCB for mounting, the electronic component identification device 100 can confirm the position of the electronic component P, the posture of the electronic component P, etc. In particular, when the electronic component P has a pin L protruding, the electronic component identification device 100 can irradiate light to such a pin L and sense the light reflected from the pin L, thereby confirming the position and posture of the electronic component P.

[0051] Specifically, the head 10 can pick up the electronic component P from the electronic component supply unit 20 and transfer it to the electronic component mounting unit 30 to be mounted on the circuit substrate PCB. At this time, the head 10 can achieve lifting movement and left-right linear movement.

[0052] The head 10 can pick up the electronic component P from the electronic component supply unit 20 and transfer it to the electronic component identification device 100. At this time, the light generating unit 111 can generate light to supply to the light diffusion unit 112. In this case, the light emitted from the light generating unit 111 can be linear. The light diffusion unit 112 can divide the linear light into a plurality of lights or expand the range of the light to emit.

[0053] As described above, the light passing through the light diffusion portion 112 may collide with the reflector 122 at various angles, and may reach the reflector 122 at various positions and be reflected. In this case, the light may be reflected in various directions at the reflector 122. Furthermore, the light reflected from a portion of the reflector reaches other portions of the reflector 122, and the light reaching other portions of the reflector 122 may be reflected and reach other portions of the reflector 122. In this case, the light may continue to be reflected at the reflector 122, and may be infinitely reflected inside the opening 123. In particular, after a certain period of time, the entire opening 123 may be filled with the reflected light.

[0054] When the head 10 arranges the pins L of the electronic component P in the opening 123 as described above, a part of the light passing through the inside of the opening 123 may collide with each pin L, so that the path will be changed. In particular, the path of a part of the light that collides with each pin L may be changed to be incident on the imaging unit 130 side. In this case, the imaging unit 130 can sense each pin L due to the light that collides with each pin L. At this time, in the case where a plurality of pins L are arranged, the outlines of the plurality of pins L can be recognized by the imaging unit as dark parts.

[0055] When the above process is finished, the shooting unit 130 may transmit the captured image to a separately configured control unit (not shown). At this time, the control unit may identify the position and posture of the electronic component P based on the image captured by the shooting unit 130. The control unit compares the captured image with the preset image, and if it is determined that the position and posture of the electronic component P are different from the preset position and posture, the control unit may control the head 10 to change the posture of the head 10. As another embodiment, the control unit may also control the head 10 to change the moving path of the head 10 so that the electronic component P is mounted to the correct position of the circuit substrate PCB. Afterwards, the control unit may move the head 10 to the electronic component mounting unit 30, and control the head 10 so that the electronic component P of the head 10 is mounted to the correct mounting position of the circuit substrate PCB.

[0056] According to this, the electronic component identification device 100 can identify the electronic component P with a simple structure. In particular, the electronic component identification device 100 can correctly and accurately identify the pins of the electronic component P.

[0057] The electronic component recognition device 100 can obtain a clear image of the lead L of the electronic component P by arranging the lead L on a surface through which light passes in infinite repetition.

[0058] The electronic component identification device 100 minimizes the components to minimize the overall size of the electronic component identification device 100 , so that it can be installed in various places and various devices.

[0059] Furthermore, the electronic component identification device 100 is disposed in a smaller area on the moving path of the head 10 so that the moving path of the head 10 can be minimized.

[0060] Figure 6 1 is a plan view showing a light source section and a reflection section of an electronic component identifying device according to another embodiment of the present invention. Figure 7 It is shown Figure 6 A cross-sectional view of the first light source portion shown in FIG. Figure 8 It is shown Figure 1 A cross-sectional view of the first light source portion shown in FIG.

[0061] Reference Figures 6 to 8 The electronic component identification device may include a light source unit 110-1, a reflection unit 120-1, a camera unit (not shown) and a main body unit (not shown). Figures 1 to 5 The same or similar to those described in , so the detailed description will be omitted.

[0062] The light source unit 110-1 and the reflector unit 120-1 may be provided in plurality. In this case, the number of the light source units 110-1 and the number of the reflector units 120-1 are the same. For the sake of convenience, the following detailed description is mainly based on the case where the light source unit 110-1 and the reflector unit 120-1 are provided in two.

[0063] The light source unit 110-1 may include a first light source unit 110-1A and a second light source unit 110-1B disposed to be spaced apart from each other, and the reflective unit may include a first reflective unit 120-1A and a second reflective unit 120-1B connected to each other.

[0064] In this case, the first light source unit 110-1A and the second light source unit 110-1B may be disposed at the first reflective unit 120-1A or the second reflective unit 120-1B. At this time, the first light source unit 110-1A and the second light source unit 110-1B may be disposed in the same direction with the space between the first reflective unit 120-1A and the second reflective unit 120-1B as a reference.

[0065] The first light source unit 110-1A may include a first light generating unit 111-1A and a first light diffusing unit 112-1A connected to the first light generating unit 111-1A and diffusing the light emitted from the first light generating unit 111-1A. Furthermore, the first light source unit 110-1A may include a first light source body unit 113-1A that receives the first light generating unit 111-1A and the first light diffusing unit 112-1A inside for fixing. At this time, as described above, the first light generating unit 111-1A may include a laser diode. Furthermore, as described above, the first light diffusing unit 112-1A may include a cylindrical lens or a diffractive optical element having a circular or elliptical cross-section. For the sake of convenience, the following detailed description will be mainly based on the case where the first light diffusing unit 112-1A includes a lens. The first light diffusing unit 112-1A may be formed in a columnar shape. At this time, the length direction of the first diffusing unit 112-1A may be relative to the traveling direction of the light emitted from the first light generating unit 111-1A (for example, Figure 7 The Y direction) is the vertical direction (for example, Figure 7 As in the above case, the light emitted from the first light generating unit 111-1A is incident on the first reflecting unit 120-1A after the light is emitted from the light diffusing unit 112-1A to expand the irradiation range.

[0066] The first light source unit 110-1B may include a second light generating unit 111-1B and a second light diffusing unit 112-1B. At this time, the second light generating unit 111-1B may be arranged in the first reflective shell 121-1A. The second light diffusing unit 112-1B may be separated from the second light generating unit 111-1B and arranged between the first reflective shell 121-1A and the second reflective shell 121-1B. In this case, the light emitted from the second light generating unit 111-1B passes through the opening of the first reflective shell 121-1B and is incident on the opening side of the second reflective shell 121-1B. In particular, the first reflective shell 121-1A and the second reflective shell 121-1B are formed with grooves or holes to allow the light of the second light generating unit 111-1B to pass through. The second light diffusing unit 112-1B may be in the same or similar shape as the first light diffusing unit 112-1A. At this time, the second light diffuser 112 - 1B may diffuse the light emitted from the second light generator 111 - 1B and incident after passing through the first reflective housing 121 - 1A, thereby guiding the light to the opening side of the second reflective housing 121 - 1B.

[0067] In the above case, the first light source unit 110 - 1A and the second light source unit 110 - 1B are arranged in the same direction, so that the installation space of the electronic component identifying device can be reduced.

[0068] The first reflective portion 120-1A may include a first reflective shell 121-1A and a first reflective plate 122-1A. At this time, the first reflective shell 121-1A may be formed in a variety of shapes. In particular, the corner portion of the first reflective shell 121-1A may be formed in a curved (arc-shaped) shape. And, the first reflective plate 122-1A may be configured on the inner surface of the first reflective shell 121-1A along the shape of the curved corner portion of the first reflective shell 121-1A. The first reflective plate 122-1A may not be configured at the portion through which the light emitted from the first light source portion 110-1A passes or at the portion of the first reflective shell 121-1A where the second light generating portion 111-1B is configured. As another embodiment, the first reflective plate 122-1A may include a half mirror configured at the portion through which the light emitted from the first light source portion 110-1A passes or at the portion of the first reflective shell 121-1A where the second light generating portion 111-1B is configured. The first reflective plate 122-1A as described above and the above Figures 1 to 5 The same or similar to those described in , so the detailed description is omitted.

[0069] The second reflective portion 120-1B may include a second reflective housing 121-1B and a second reflective plate 122-1B. At this time, the second reflective housing 121-1B is connected to the first reflective housing 121-1A. In addition, the second reflective plate 122-1B may be disposed on the inner surface of the second reflective housing 121-1B. The second reflective housing 121-1B and the second reflective plate 122-1B are respectively the same or similar to the first reflective housing 121-1A and the first reflective plate 122-1A described above, so detailed description is omitted.

[0070] The operation of the electronic component identification device described above is similar to the Figures 1 to 5 Same or similar to that described in .

[0071] Specifically, a plurality of heads (not shown) respectively configure a plurality of electronic components (not shown) on the first reflective portion 120-1A and the second reflective portion 120-1B, and the first light source portion 110-1A can provide light to the inside of the first reflective portion 120-1A, and the second light source portion 110-1B can provide light to the second reflective portion 120-1B. At this time, the light emitted from the second light generating portion 111-1B is incident on the second light diffusing portion 112-1B through the inside of the first reflective portion 120-1A, and the light diffused by the second light diffusing portion 112-1B can enter the second reflective portion 120-1B to repeat infinitely.

[0072] As described above, when light is infinitely reflected inside the first reflecting part 120-1A and the second reflecting part 120-1B, each of the shooting parts senses the light colliding with the pins of the electronic components respectively arranged in the first reflecting part 120-1A and the second reflecting part 120-1B, thereby sensing the position, posture, etc. of the electronic components.

[0073] Afterwards, the head portion is adjusted based on the image captured by the camera unit so that the position and posture of the electronic component can be adjusted to a preset position and posture. As another embodiment, when the electronic component is mounted on a circuit substrate (not shown), the head portion can be adjusted based on the image captured by the camera unit so that the electronic component is arranged at a correct mounting position on the circuit substrate.

[0074] Furthermore, the electronic component identification device arranges each light source unit 110 - 1 in a direction to minimize interference with other components and minimize the installation space of the device itself.

[0075] In particular, in the case where the electronic component includes pins, in the case of directly irradiating light toward the electronic component, it is impossible to correctly obtain an image of the pins of the electronic component because the light is incident on the pins of the electronic component from multiple angles, and thus it may be difficult to correctly know the position of the electronic component.

[0076] However, the electronic component identification device forms an area of ​​infinite light reflection in each reflection part 120-1 by emitting light from each light source part 110-1, and arranges the pins of the electronic component in such an area to sense the light reflected from the pins, thereby being able to improve the recognition rate of the electronic component when the electronic component includes pins, and furthermore, the electronic component can be accurately and correctly identified.

[0077] Fig. 9 is a perspective view showing an electronic component identifying device according to still another embodiment of the present invention. Fig.10 It is shown Fig. 9 A plan view of the light source portion and the reflective portion shown in FIG. Fig.11 It is shown Fig.10 A plan view of the reflecting portion shown in FIG.

[0078] Reference Figures 9 to 11 , the electronic component identification device 100-2 may include a light source unit 110-2, a reflection unit 120-2, a camera unit 130-2, a body unit 140-2, and a direct light source unit 150-2. In this case, the body unit 140-2 may include a main body 141-2 and a partition 142-2. This camera unit 130-2 and the body unit 140-2 are similar to the above Figures 1 to 5 The same or similar to those described in , so the detailed description is omitted.

[0079] At least one light source unit 110 - 2 may be provided. For the sake of convenience, the following detailed description will be mainly based on the case where a plurality of light source units 110 - 2 are provided.

[0080] The light source unit 110-2 may include a light generating unit 111-2, a light diffusion unit 112-2, a light source body unit 113-2, and a light guide 114-2. The light generating unit 111-2 may be accommodated inside the light source body unit 113-2 and configured in the body unit 140-2. In this case, the light generating unit 111-2 may include a laser diode. The light diffusion unit 112-2 may be configured in each reflecting unit 120-2. In this case, the light diffusion unit 112-2 may diffuse light into each reflecting unit 120-2. The light guide 114-2 may include an optical fiber and the like to connect the light diffusion unit 112-2 and the light generating unit 111-2. In this case, the light guide 114-2 may guide the light generated from the light generating unit 111-2 to the light diffusion unit 112-2.

[0081] In the above case, the light generating unit 111-2 may be disposed in other devices or other places other than the main body 140-2. In particular, in the above case, the light generating unit 111-2 may be disposed according to the positional relationship with other devices.

[0082] The reflective portion 120-2 may include a reflective housing 121-2 and a reflective plate 122-2. At this time, the reflective housing 121-2 may include an opening 123-2 inside, and the shape of the opening 123-2 may be an octagonal shape. For example, the opening 123-2 is a quadrangular shape and the corners may be chamfered. The reflective plate 122-2 may be provided in plurality and arranged on the inner surface of the reflective housing 121-2. In this case, the reflective plate 122-2 may also be arranged on the chamfered opening 123 portion, so as to reflect the light incident to the inside of the opening 123-2 on the entire inner surface of the reflective housing 121-2.

[0083] The reflector 122-2 as described above may include a linear reflector 122-2A disposed on a plane portion of the reflective housing 121-2 and a corner reflector 122-2B disposed on a chamfered corner portion of the reflective housing 121-2. In this case, the linear reflector 122-2A and the corner reflector 122-2B may be formed as one body. As another embodiment, the linear reflector 122-2A and the corner reflector 122-2B may also be separated from each other and respectively disposed on the reflective housing 121-2. For ease of description, the following detailed description is mainly based on the case where the linear reflector 122-2A and the corner reflector 122-2B are disposed on the reflective housing 121-2 in a state separated from each other.

[0084] The direct light source unit 150-2 can directly irradiate light to the electronic component (not shown). In this case, the direct light source unit 150-2 may include an organic light emitting diode and be provided in plurality. In this case, the plurality of direct light source units 150-2 are arranged spaced apart from each other and can be arranged inside the main body 140-2 to form columns and rows. In particular, such a direct light source unit 150-2 can be used in situations such as electronic components without pins and surface mount devices (SMD: Surface mount device) in which the pins of the electronic components are formed on the side of the electronic components.

[0085] In the operation of the electronic component recognition device as described above, when the type of the electronic component is a surface mount device, the head (not shown) can absorb the electronic component and be arranged on the reflective portion 120-2 or be arranged on the electronic component recognition device and then supply light to the electronic component through the direct light source portion 150-2. The light supplied from the direct light source portion 150-2 collides with and reflects the electronic component itself and then enters the shooting portion 130-2. At this time, in order to remove noise from the image of the electronic component absorbed on the adjacent head taken from each shooting portion 130-2 or to obtain a clear image, the partition 142-2 can divide the space inside the main body 141-2.

[0086] In addition, when the electronic component is not a surface mount device but a pin (not shown) protrudes vertically from the lower surface of the electronic component toward the imaging unit 130-2, the operation of the direct light source unit 150-2 can be stopped and each light source unit 110-2 can be operated. The light generated from each light source unit 110-2 can be supplied to the inside of each reflecting unit 120-2 through each light guide 114-2 and each light diffusion unit 112-2.

[0087] Afterwards, when the light incident into each reflective portion 120-2 is infinitely reflected, the reflective portion 120-2 may form a surface light source. At this time, the head may overlap the pins of the electronic components and arrange them inside the reflective portion 120-2.

[0088] The light that hits the lead is reflected and enters the imaging unit 130 - 2 , and the imaging unit 130 - 2 can obtain an image of the lead of the electronic component through the reflected light.

[0089] Afterwards, the control unit (not shown) can determine the position and posture of the electronic component based on the image captured by the imaging unit 130-2, and can arrange the position and posture of the electronic component through the head. As another embodiment, after the control unit knows the position of the circuit substrate (not shown) on which the electronic component is to be mounted, it can arrange the electronic component at the position to be mounted in the circuit substrate based on the above-mentioned sensing result, and can mount it on the circuit substrate.

[0090] Therefore, the electronic component identification device 100 - 2 can be disposed in a small installation location and can minimize interference with other devices.

[0091] The electronic component identification device 100 - 2 can improve the recognition rate of the electronic component having pins, and can also identify the electronic component having various shapes.

[0092] The electronic component identification device 100 - 2 can accurately and correctly identify the electronic component with a simple structure.

[0093] Although the present invention has been described with respect to the above preferred embodiments, various modifications and changes can be made without departing from the spirit and scope of the invention. Therefore, any modification or variation that falls within the spirit of the present invention is intended to be included within the scope of the appended claims.
