Description
Technical Field
The present invention relates to an electronic component stabilizing device, and more particularly, to an electronic component stabilizing device suitable for an appearance inspection apparatus.
Background
The existing electronic component appearance detection equipment generally arranges electronic components on a rotating disc after arranging the electronic components in a row through a vibration disc, the rotating disc conveys the electronic components to the front of a lens for image taking so as to detect appearance, and then the electronic components are classified and collected through a collecting device according to detection results.
Fig. 1 is a schematic diagram of a conveying mechanism of a conventional appearance inspection apparatus, and fig. 2 is a partial cross-sectional view of a blanking portion of fig. 1. As shown in fig. 1 and 2, the conventional appearance inspection apparatus includes a feeding device 11, a feeding rail 12, a low vibration block 13, a glass disk 14, and a material guide block 15. The feeding device 11 sends out the electronic component 10 through the blanking track 12, and the bottom of the blanking track 12 is provided with a low vibration block 13 which is locked under the blanking track 12 by a fixing screw 131 to provide a bridge for receiving the electronic component 10 falling from the blanking track 12 to the glass disc 14. When the electronic components 10 are vibrated by the blanking track 12 and fall onto the low vibration block 13, the electronic components 10 on the low vibration block 13 are pushed from the rear and fall onto the rotating glass disc 14, the glass disc 14 receives the falling electronic components 10, and the linear speed of the glass disc 14 is greater than the feeding speed of the blanking track 12, so that the electronic components 10 can be pulled away from each other after falling onto the glass disc 14, thereby facilitating the camera lens at the rear end to take images for appearance detection, and finally collecting the electronic components 10 into the material collecting device 16.
Because the rotating speed of the glass disc 14 is greater than the feeding speed of the feeding rail 12, the problem that the electronic component 10 is prone to have a tilted and unstable blanking when falling on the glass disc 14 is solved, a material guide block 15 is additionally arranged above the glass disc 14 and is fixedly arranged near the blanking position and has a cambered surface, and through the rotation of the glass disc 14, the edge of the electronic component 10 touches the cambered surface of the material guide block 14, so that the electronic component 10 is guided to be in a tangential direction.
In the prior art, for the appearance inspection equipment of the glass disc 14 with low rotation speed (below 5 rpm), the problem of unstable material skew can be overcome, but when the rotation speed of the glass disc 14 is more than twice of the current production rotation speed, the problem of unstable material skew cannot be overcome, and the skew ratio increases with the increase of the rotation speed.
In addition, in order to attach the electronic component 10 to the glass disk 14 for transportation, the glass disk 14 is charged in the prior art, so that the electronic component 10 is attached to the glass disk 14 by electrostatic attraction. However, the static electricity supplied by the static brush, the ionizer or the conductive plate increases the cost of the equipment, and the operator may be charged by the static electricity, which causes safety problems. In addition, the static electricity supply device is also easily stained with dust, thereby increasing the difficulty of cleaning.
Therefore, in order to overcome the drawbacks of the prior art, it is necessary to provide an electronic component stabilizing apparatus to overcome the problem of unstable blank skew, and further improve the productivity of the appearance inspection apparatus.

Detailed Description
Some embodiments which embody features and advantages of the invention will be described in detail in the description which follows. As will be realized, the invention is capable of modifications in various obvious respects, all without departing from the scope of the present invention, and the description and drawings are to be regarded as illustrative in nature, and not as restrictive.
The invention mainly provides an electronic element stabilizing device which is suitable for appearance detection equipment and is constructed for improving blanking stability so as to improve the capacity of the appearance detection equipment. Fig. 3 and 4 are schematic diagrams illustrating different viewing angles of the appearance inspection apparatus according to the present invention. As shown in fig. 3 and 4, the appearance inspection apparatus 2 includes a conveying device 3, a feeding device 4, an electronic component stabilizing device 5, an image capturing device 6, and a material collecting device 7, which are all disposed on a base 21 of the appearance inspection apparatus 2.
The transport device 3 includes a rotary disk 31 and a motor 32. In an embodiment, the rotating plate 31 is a circular transparent plate made of glass, the rotating plate 31 is horizontally disposed and is power-connected to the motor 32, so that the rotating plate 31 can be driven by the motor 32 to horizontally rotate, and serves as a carrying platform for the electronic component 10, and the electronic component 10 is moved to each station of the image capturing device 6 for appearance detection and moved to the material collecting device 7 for final material collecting operation through rotation. The path of the electronic component 10 moving with the rotating disc 31 is defined as a material line (as shown by the dotted line on the rotating disc 31 in fig. 6), which is a circular path with a radius slightly smaller than that of the rotating disc 31.
The feeding device 4 comprises a vibration plate 41 and a feeding rail 42. In one embodiment, the vibration plate 41 is a circular plate configured to move the electronic components 10 from the center of the plate along a spiral path of the circular plate by circular vibration, and sequentially arranged to an outermost path to enter the feeding track 42. The feeding rail 42 is connected to the vibration plate 41, and is a linear concave groove for carrying the electronic device 10 and making the electronic device 10 arranged in a linear shape, and pushing the electronic device 10 to linearly move forward and fall onto the rotation plate 31. The end of the blanking track 42 extends to be close to but not in contact with the surface of the rotating disk 31, and the blanking track 42 is preferably arranged along the tangential direction of the rotating disk 31.
The appearance inspection apparatus 2 includes a plurality of image capturing devices 6 disposed around the rotating plate 31, and each image capturing device 6 is disposed adjacent to the rotating plate 31 at different angles according to different image capturing angles. Each image capturing device 6 includes a photographing lens 61 and a vertical slide rail 62, wherein the photographing lens 61 is slidably disposed on the vertical slide rail 62 and configured to capture images of various viewing angles of the electronic device 10 for appearance inspection. The image capturing device 6 may also include a reflector corresponding to the rotating disc 31 for reflecting the electronic element 10 carried on the rotating disc 31, so that the photographing lens 61 can collect the image of the electronic element 10; the number of the image capturing devices 6 arranged on the rotating disc 31 can be reduced by the arrangement of the reflecting mirror.
The material collecting device 7 comprises a plurality of material collecting boxes 71 and a plurality of blowing nozzles 72 corresponding to the material collecting boxes 71, wherein each blowing nozzle 72 faces to the corresponding material collecting box 71 and is respectively connected with a stable positive pressure air source capable of adjusting pressure. Each blowing nozzle 72 is provided with an electromagnetic valve, and each electromagnetic valve is electrically connected with the controller, so that the controller can control the time point of blowing air by each blowing nozzle 72 through the electromagnetic valve, thereby blowing each electronic component 10 into the corresponding collecting box 71 according to the detection result of each electronic component 10. In one embodiment, the material collecting device 7 includes four material collecting boxes 71, wherein two material collecting boxes 71 are used for collecting the electronic components 10 with bad detection, and can be set to collect electronic components 10 with different bad degrees (for example, one material collecting box 71 is used for collecting the electronic components 10 with damaged appearance, the other material collecting box 71 is used for collecting the electronic components 10 with uneven appearance, a plurality of electronic components 10 with uneven appearance can be electroplated again and then used after detection), one material collecting box 71 is used for collecting the electronic components 10 with good detection, and the other material collecting box 71 is used for collecting the electronic components 10 which need to be retested, such as the electronic components 10 which are not successfully imaged. Of course, the number and usage configuration of the aggregate boxes 71 can be adjusted according to different requirements and is not limited to the aforementioned embodiments.
In order to effectively obtain the images of the electronic components 10 at different viewing angles, the electronic components 10 need to maintain a certain distance on the rotating disc 31 for the image taking lens 61 of the image taking device 6 to take images, so the rotating speed of the rotating disc 31 is inevitably greater than the blanking speed of the electronic components 10 to separate the electronic components 10 from each other. Therefore, when the electronic device 10 falls on the rotating disk 31 with a faster rotation speed, it is difficult to avoid the skew phenomenon from affecting the rear-end image capturing quality. Therefore, in order to improve the defect, the appearance inspection apparatus 2 of the present invention further comprises an electronic component stabilizing device 5 configured to increase the stability of the blanking for effective appearance inspection.
Fig. 5 to 8 are schematic views showing a partial structure of the appearance inspection apparatus and the carried electronic components, so as to clearly illustrate the design of the electronic component stabilizing apparatus of the present invention. Please refer to fig. 3 to fig. 8. The electronic component stabilizing device 5 is disposed at the end outlet (i.e. the blanking position) of the blanking track 42 and outside the material running line (as shown by the circular dotted line on the rotating disc 31) of the rotating disc 31. The electronic component stabilizing apparatus 5 includes a material guiding wheel 51, a motor 52 and a negative pressure generator 53. The material guide wheel 51 is substantially disc-shaped, and is horizontally disposed similarly to the rotary plate 31, and is power-connected to the motor 52, so that it can be driven by the motor 52 to horizontally rotate. The material guiding wheel 51 is disposed outside the material line and has a smooth arc surface 511. In one embodiment, the arcuate surface 511 circumscribes the row of material. When the electronic components 10 touch the arc surface 511 of the guiding wheel 51, the electronic components can be guided to be sequentially arranged on the material traveling line along with the rotation of the guiding wheel 51.
In one embodiment, the tangential speed of the arc surface 511 of the guiding wheel 51 is the same as the tangential speed of the contact surface of the rotating disc 31 where the electronic component 10 is carried, in other words, the rotational linear speed V2 of the guiding wheel 51 is the same as the traveling speed V1 of the electronic component 10 on the rotating disc 31, so that the distance between the front and the rear materials can be stabilized. The rotation direction of the guiding wheel 51 is opposite to the rotation direction of the rotating disc 31, for example, the rotating disc 31 rotates in a counterclockwise direction and the guiding wheel 51 rotates in a clockwise direction, so as to bring the electronic component 10 away from the blanking position and move toward the image capturing device 6. Alternatively, when the arrangement direction of the feeding rail 42 is changed, the rotating plate 31 may be rotated counterclockwise and the material guide wheel 51 may be rotated clockwise.
In one embodiment, the gap H between the bottom of the guiding wheel 51 and the surface of the rotating disc 31 is about 1/3 to 2/3 of the thickness of the electronic component 10, so that the electronic component 10 can abut against the arc surface 511 of the guiding wheel 51 and cannot fall into the bottom of the guiding wheel 51.
The negative pressure generator 53 is disposed at the bottom of the guide wheel 51, but does not rotate with the guide wheel 51. In one embodiment, the negative pressure generator 53 is disposed on a side near the outlet of the end of the feeding rail 42. The negative pressure generator 53 includes a duct 531, the direction of the duct 531 is substantially perpendicular to the tangential direction of the material line, and an opening 532 is formed at one end of the duct 531 close to the blanking position. When the negative pressure generator 53 forms negative pressure in the duct 531 by suction, for example, a suction force is generated through the opening 532, so that the electronic component 10 falling from the feeding track 42 is sucked to the material guiding wheel 51, adhered to the arc surface 511 of the material guiding wheel 51 and the surface of the rotating disc 31, and pushed forward along with the rotation of the material guiding wheel 51. Since the tangential speed of the arc surface 511 of the guiding wheel 51 is the same as the tangential speed of the contact surface of the rotating disc 31 at the position where the electronic component 10 is carried by the rotating disc 31, when the electronic component 10 is not attracted by the suction force of the negative pressure generator 53 and is separated from the guiding wheel 51, the advancing speed of the electronic component 10 is the same as the tangential speed of the contact surface of the rotating disc 31 at the position where the electronic component 10 is carried by the rotating disc 31, and the electronic component can stably advance on the rotating disc 31 along the material routing, so that the blanking stability can be further improved.
In one embodiment, when the electronic component 10 is separated from the material guiding wheel 51, the longitudinal direction of the electronic component 10 forms an angle with the material line
Maintained at an angular range of about 0 to 15 degrees.
In one embodiment, the negative pressure generator 53 may be a vacuum tube device, but is not limited thereto.
In one embodiment, the distance W between the circular arc surface 511 of the material guiding wheel 51 corresponding to the opening 532 of the duct 531 of the negative pressure generator 53 and the end outlet of the blanking track 42 is approximately equal to the pitch of one material, i.e. approximately equal to the length of the electronic component 10, and the distance W can be adjusted according to the lengths of different electronic components 10.
In one embodiment, the electronic component stabilizing device 5 improves the blanking stability, so that the end of the blanking rail 42 does not need to be provided with a low vibration block.
In one embodiment, the appearance inspection apparatus 2 may optionally include a material guiding device 8 disposed downstream of the electronic component stabilizing device 5. The material guiding device 8 includes a material guiding block 81 disposed above the rotating disc 31 and located inside the material line. The guiding block 81 has a smooth arc surface 811 at a side facing the material line, so that when the edge of the electronic component 10 touches the arc surface 811 of the guiding block 81, the electronic component 10 can be further guided to a tangential direction. In addition, since the electronic component stabilizing device 5 substantially avoids the problem of oblique blanking, most of the electronic components 10 are aligned on the material traveling line when they are separated from the material guiding wheel 51, and thus, in one embodiment, the appearance detecting apparatus 2 may not need to be provided with the material guiding device 8.
In summary, according to the design of the electronic component stabilizing apparatus 5 of the present invention, when the electronic component 10 falls from the outlet of the feeding track 42 of the feeding device 4 onto the surface of the rotating disc 31, the electronic component 10 is firstly attracted to the material guiding wheel 51 by the suction force of the negative pressure generator 53, and is attached to the material guiding wheel 51 and pushed forward along with the rotation of the material guiding wheel 51. Since the linear velocity of the guiding wheel 51 is the same as the speed of the electronic component 10 traveling on the rotating disc 31, when the electronic component 10 is no longer attracted by the suction force of the negative pressure generator 53 and is separated from the guiding wheel 51, the electronic component 10 can stably and positively advance on the rotating disc 31 along the material traveling path. Therefore, the electronic component stabilizing device 5 of the present invention can further improve the blanking stability, overcome the problem of unstable blanking skew in the prior art, enable the image capturing device 6 at the rear end to effectively capture images, and improve the detection efficiency of the appearance detection device 2. On the other hand, since the blanking stability is greatly improved, the rotation speed of the rotating disc 31 can be increased to about 5rpm to 12rpm (preferably 10rpm to 12 rpm), so as to improve the productivity of the appearance inspection apparatus 2, for example, 8000 or more materials can be detected in one minute, thereby greatly improving the industrial application value of the appearance inspection apparatus 2. In addition, through the design of the electronic component stabilizing device 5, the appearance inspection apparatus 2 of the present invention does not need to use a static electricity providing device to make the electronic component 10 adhere to the rotating disk 31 through electrostatic adsorption force, so compared with the existing appearance inspection apparatus having the static electricity providing device, the appearance inspection apparatus 2 of the present invention can also reduce the equipment cost, increase the safety of the operator, and avoid the cleaning problem of the static electricity providing device.
Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to one skilled in the art that various modifications can be made without departing from the scope of the invention as defined in the appended claims.
