Description

[Technical Field]

[0001] The present invention relates to an electronic component inspection machine, and more particularly to an electronic component inspection machine that facilitates the loading and unloading of electronic components. [Background technology]

[0002] Conventional electronic component inspection machines generally include a turntable and multiple lenses corresponding to the turntable. Electronic components are placed on the turntable one by one and rotated by the turntable, passing in front of each lens. Each lens captures an image of the electronic component from a different direction, and the appearance of each electronic component is then inspected based on the captured image. Summary of the Invention [Problem to be solved by the invention]

[0003] Conventional electronic component inspection machines have the problem of inconveniently transporting electronic components. As a result, electronic components are often placed on the turntable at an angle. When electronic components are placed on the turntable at an angle, inspections based on acquired images can result in erroneous judgments, or it can be difficult to accurately determine whether the appearance meets standards.

[0004] Furthermore, if electronic components that have passed inspection are placed in the wrong position after collection, they are likely to become jammed on the rails when transported on the rails.

[0021] The detailed description and technical contents of the present invention will be described below with reference to the drawings, which are for illustrative purposes only and are not intended to limit the present invention.

[0022] Fig. 1 is a schematic perspective view of an electronic component inspection machine according to an embodiment of the present invention. Fig. 2 is a top view of an electronic component inspection machine according to an embodiment of the present invention. Referring to Figs. 1 and 2, an embodiment of the present invention provides an electronic component inspection machine including a tray conveying device 100, a receiving device 200, an appearance inspection device 400, a supplying device 500, and an attitude sorting device 600.

[0023] Fig. 3 is a schematic perspective view of a tray conveying device of an electronic component inspection machine according to one embodiment of the present invention. Figs. 4 to 6 are schematic views showing a state in which the tray conveying device of an electronic component inspection machine according to one embodiment of the present invention is used. Referring to Figs. 1 to 6, the tray conveying device 100 is used to carry in trays 10 on which a plurality of electronic components 20 are placed and to carry out empty trays 10. The receiving device 200 carries the electronic components 20 in the trays 10 to the appearance inspection device 400 for appearance inspection, the supplying device 500 outputs the electronic components 20 that have passed the appearance inspection from the appearance inspection device 400 to the next station, and the attitude sorting device 600 detects whether the arrangement attitude of the output electronic components 20 is correct in response to a request from the next station.

[0024] 3 to 6, the tray transport device 100 includes a carriage 110, a first platform 121, a second platform 122, a first fork unit 131, and a second fork unit 132. The first fork unit 131 is arranged to be able to rise and fall relative to the first platform 121, and is capable of translating between the first platform 121 and the carriage 110. Specifically, the first fork unit 131 is arranged on a first lift mechanism 141, and the first lift mechanism 141 is arranged on a first slide rail 151, which extends between the first platform 121 and the carriage 110. The lifting and lowering operation of the first lift mechanism 141 and the translation of the first slide rail 151 can be driven by components such as a pneumatic cylinder or a linear actuator. The second fork unit 132 is arranged to be able to rise and lower relative to the second platform 122, and is capable of translating between the second platform 122 and the carriage 110. Specifically, the second fork portion 132 is arranged on a second lift mechanism 142, which is arranged on a second slide rail 152, which extends between the second platform 122 and the carriage 110, and the lifting and lowering operation of the second lift mechanism 142 and its translation on the first slide rail 151 can be driven by components such as a pneumatic cylinder or a linear actuator.

[0025] Specifically, in this embodiment, the first slide rail 151 and the second slide rail 152 are arranged on one side of the translation direction 111 of the carriage 110. Furthermore, the first slide rail 151 and the second slide rail 152 are arranged parallel to each other and perpendicular to the translation direction 111 of the carriage 110. However, the present invention is not limited to the above-described embodiment.

[0026] 4 to 6 , a worker first places a tray 10 on which a plurality of electronic components 20 are placed on the first platform 121. The electronic components 20 are arranged in a row within the tray 10, and at least one tray 10 can be placed on the first platform 121. The first fork unit 131 moves along the first slide rail 151, and when it reaches below a predetermined tray 10, it rises and lifts the tray 10. Next, the first fork unit 131 moves along the first slide rail 151 to load the tray 10 onto the carriage 110. Next, the first fork unit 131 descends to release the tray 10. The carriage 110 translates the tray 10, aligning the electronic components 20 in the tray row by row in the receiving device 200 and loading them into the receiving device 200. After all the electronic components 20 in the tray 10 have been transferred to the receiving device 200 and the tray 10 is empty, the carriage 110 moves the tray 10 to align it with the second slide rail 152. The second fork unit 132 moves along the second slide rail 152 and, when it reaches below the desired tray 10, rises to lift the tray 10. Next, the second fork unit 132 moves along the second slide rail 152 to transfer the tray 10 to the second platform 122. Next, the second fork unit 132 descends to release the tray 10. The tray conveying device 100 described above smoothly performs the process of loading and unloading the tray 10 via the first platform 121 and the second platform 122, thereby smoothly connecting human work processes and automated work processes.

[0027] FIG. 7 is a schematic perspective view of a receiving device of an electronic component inspection machine according to one embodiment of the present invention. FIGS. 8 and 9 are schematic views showing a state in use of a receiving device of an electronic component inspection machine according to one embodiment of the present invention. Referring to FIGS. 1 to 2 and 7 to 9, receiving device 200 includes a receiving chute 210, a push rail 220, and a push rod 230. Receiving chute 210 has an entrance end 211 and an exit end 212 at both ends. The entrance end 211 of receiving chute 210 is disposed corresponding to the other side in the translation direction 111 of carriage 110. Push rod 230 is pivotally attached to push rail 220 so as to be translatable along the longitudinal direction of receiving chute 210. Specifically, push rail 220 includes a rail 221 and a slider 222 disposed on rail 221. The slider 222 is translatable along rail 221, and push rod 230 is pivotally attached to slider 222. In this embodiment, the receiving chute 210 and the rail 221 of the push rail 220 are parallel to each other in the vertical direction, and the push rod 230 is disposed corresponding to the inlet end 211 of the receiving chute 210. The push rod 230 is provided with a magnetically attracting member 240 and an elastic member 250. The magnetically attracting member 240 and the elastic member 250 are disposed on opposite sides of the push rod 230 in the vertical direction of the receiving chute 210, the magnetically attracting member 240 attracts the slider 222, and the elastic member 250 is connected to the slider 222 in a pre-stretched state.

[0028] 1, 7, and 8, the tray 10 is translated by the carriage 110, and the electronic components 20 in the tray 10 are aligned row by row with the receiving chute 210 and the push rod 230. Then, the push rod 230 is moved along the push rail 220 toward the receiving chute 210, and the push rod 230 pushes the electronic components 20 in the tray 10 row by row through the entrance end 211 into the receiving chute 210. The electronic components 20 pass through the receiving chute 210 and are carried into the appearance inspection device 400 one by one from the exit end 212 of the receiving chute 210. A vibration motor can be selectively connected to the receiving chute 210 to vibrate the receiving chute 210 and promote the movement of the electronic components 20 therein.

[0029] 8 and 9, if a blockage occurs while the electronic component 20 is being pushed through the receiving chute 210 or the tray 10, the resistance experienced by the push rod 230 increases instantaneously. As a result, the push rod 230 overcomes the magnetic attraction force of the magnetic attraction member 240 and becomes disengaged, thereby stopping the action of pushing the electronic component 20. In addition, the elastic member 250 retracts the push rod 230 from the electronic component 20, thereby preventing the push rod 230 from pressing against or damaging the electronic component 20.

[0030] 1 and 2, the visual inspection apparatus 400 includes a rotating platform 410 and a plurality of image acquisition units 430. The rotating platform 410 has a transparent disk- or ring-shaped structure, and a mounting surface 411 is provided on the rotating platform 410. A predetermined rotation path 401 that surrounds the center of rotation of the rotating platform 410 is formed along the mounting surface 411. The image acquisition units 430 are arranged to surround the center of rotation of the rotating platform 410, and each is located near the rotating platform 410. In addition, the outlet end 212 of the receiving chute 210 is located corresponding to a position on the edge of the rotating platform 410. Specifically, the outlet end 212 of the receiving chute 210 is configured to correspond to the predetermined rotation path 401 so that the electronic components 20 are placed on the predetermined rotation path 401. As a result, each electronic component 20 is moved along the predetermined rotation path 401 by the rotating platform 410, and can pass through each image acquisition unit 430 in sequence. Each image acquisition unit 430 is disposed facing the predetermined rotation path 401 from a different direction, and acquires an image of the electronic component 20 as it passes through the predetermined rotation path 401. These image acquisition units 430 can each acquire an image of the electronic component 20 passing through from a different direction.

[0031] 10 and 11 are schematic diagrams of a guide assembly of an electronic component inspection machine according to an embodiment of the present invention. Referring to FIGS. 1-2, 10, and 11, a guide assembly 300 can be selectively positioned between the receiving device 200 and the visual inspection device 400. This guide assembly 300 accurately positions the electronic components 20 pushed out from the receiving device 200 along a predetermined rotation path 401. The guide assembly 300 is suspended above a rotation platform 410 corresponding to the outlet end 212 of the receiving chute 210. The guide assembly 300 includes at least one guide block 310a, 310b, which can be selectively positioned on either side of the predetermined rotation path 401. Each guide block 310a, 310b has a respective guide surface, which is all oriented toward the predetermined rotation path 401. In this embodiment, these guide surfaces include a pair of a primary guide surface 311a and a secondary guide surface 311b. The pair of primary guide surfaces 311a are arranged opposite each other on either side of the predetermined rotation path 401, defining a tapered path that narrows in the direction of rotation of the rotating platform 410. This allows the electronic component 20 dropped from the receiving chute 210 onto the placement surface 411 to be guided along the predetermined rotation path 401. The secondary guide surface 311b is arranged following the primary guide surface 311a in the direction of rotation of the rotating platform 410 and is arranged on one side of the predetermined rotation path 401. The secondary guide surface 311b guides the center of the electronic component 20 positioned on the predetermined rotation path 401 to be aligned with the predetermined rotation path 401. This improves the accuracy of the inspection results obtained by the visual inspection device 400. Specifically, the secondary guide surface 311b has a radius of curvature slightly smaller than the arcuate surface of the predetermined rotation path 401. Therefore, the electronic component 20 is pushed into the predetermined rotation path 401 after temporarily contacting the secondary guide surface 311b.

[0032] FIG. 12 is a schematic perspective view of an appearance filter 710 of an electronic component inspection machine according to an embodiment of the present invention. Referring to FIGS. 1 to 2 and 12, the electronic component inspection machine of the present invention may further include an appearance filter 710 that operates in conjunction with the appearance inspection device 400. The appearance filter 710 operates based on the detection results of the appearance inspection device 400. The appearance filter 710 includes a first air nozzle 711 and a first collection box 712. The first air nozzle 711 is disposed facing the rotating platform 410 and is connected to the appearance inspection device 400. Based on the detection results of the appearance inspection device 400, the appearance inspection device 400 controls the first air nozzle 711 to either blow air onto the rotating platform 410 or turn it off. The control to blow air and the control to turn it off here refer to turning on or off the air blow at a specific time (i.e., the time when the electronic component 20 passes through the first air nozzle 711) after the appearance inspection device 400 detects the electronic component 20. Specifically, the first air nozzle 711 and the first collection box 712 are disposed on either side of the predetermined rotation path 401. Therefore, when an electronic component 20 that has been determined to be a failure by the visual inspection device 400 passes through the first air nozzle 711, the first air nozzle 711 can blow the electronic component 20 into the first collection box 712.

[0033] To accommodate different rejection conditions or detection errors, multiple appearance filters (710, 710a, 710b) can be arranged along the predetermined rotation path 401 to sort and collect rejected electronic components 20. Each appearance filter (710, 710a, 710b) includes a first air nozzle (711, 711a, 711b) and a first collection box (712, 712a, 712b). The first air nozzles (711, 711a, 711b) are arranged facing the rotation platform 410 and are linked to the appearance inspection device 400. Furthermore, the first air nozzle 711b of the last appearance filter 710b can be set to a constantly open state. Then, the appearance inspection device 400 controls the first air nozzle 711b to be turned off only when the appearance inspection device 400 detects that a passed electronic component 20 has passed through the first air nozzle 711b. This prevents rejected electronic components 20 from passing through the appearance filters 710 due to operational errors in the appearance filters (710, 710a, 710b).

[0034] 13 and 14 are schematic perspective views of a supply device of an electronic component inspection machine according to one embodiment of the present invention. Referring to FIGS. 1 and 13 to 15, the supply device 500 includes a supply chute 510 and a push wheel 520. The supply chute 510 passes below the receiving chute 210. This allows the receiving chute 210 and the supply chute 510 of the electronic component inspection machine to be closely stacked one on top of the other, thereby reducing the overall volume of the electronic component inspection machine. One end of the supply chute 510 is positioned corresponding to another portion of the edge of the rotating platform 410, and the aforementioned appearance filter 710 is positioned corresponding to this end. Specifically, the appearance filter 710 is positioned sequentially between the last image acquisition unit 430 and the supply chute 510. The push wheel 520 is suspended above the mounting surface 411, and the push wheel 520 is positioned between the predetermined rotation path 401 and the supply chute 510. This allows the electronic components 20 on the predetermined rotational path 401 to be pushed along the outer edge of the push wheel 520 and moved into the supply chute 510. In this embodiment, the supply device 500 may optionally further include a push air nozzle 530. The push air nozzle 530 is arranged toward the supply chute 510 and helps to push the electronic components 20 on the predetermined rotational path 401 into the supply chute 510.

[0035] 15 and 16 are schematic perspective views of an orientation sorting device of an electronic component inspection machine according to one embodiment of the present invention. FIGS. 17 to 19 are schematic views showing the usage state of an orientation sorting device of an electronic component inspection machine according to one embodiment of the present invention. Referring to FIGS. 1 to 2 and 15 to 16, the orientation sorting device 600 includes at least one orientation filter (610a, 610b, 610c). Each orientation filter (610a, 610b, 610c) includes a sorting air nozzle (611a, 611b, 611c) and at least one corresponding second collection box 722. In this embodiment, all of these sorting air nozzles correspond to the same second collection box 722.

[0036] 16 to 18, in the orientation filters (610a, 610b) of the first mode in this embodiment, the respective selection air nozzles (611a, 611b) are arranged at predetermined positions corresponding to the boundary 21 in a specific direction on the contour of the electronic component 20. The selection air nozzles (611a, 611b) are set to a constantly open state. Specifically, as shown in FIG. 17, one selection air nozzle 611a of the first mode is arranged at a predetermined position corresponding to the boundary 21 on one side of the horizontal direction of the contour of the electronic component 20. As shown in FIG. 18, the other selection air nozzle 611b of the first mode is arranged at a predetermined position corresponding to the boundary 21 above the contour of the electronic component 20. As shown in FIGS. 17 and 18, in an electronic component 20a with an inaccurate orientation, some non-corresponding contours 21a protrude from the predetermined positions of the boundary 21 in the specific direction. When the electronic component 20a passes through the sorting air nozzles (611a, 611b) corresponding to the direction, air is blown out through the sorting air nozzles (611a, 611b) and into the second collection box 722.

[0037] 19, in a second mode of posture filter 610c in this embodiment, a sorting air nozzle 611c is arranged facing a path of the direction in which air is blown onto the electronic components (20, 20a) in the supply chute 510, and includes a light-emitting component 621c and a light-receiving component 622c. The light-emitting component 621c and the light-receiving component 622c are arranged at predetermined positions on the boundary 21 corresponding to a specific direction on the outline of the electronic component 20 / 20a. The light-emitting component 621c is arranged to irradiate a light beam toward the supply chute 510, and the light beam is arranged so that it passes just outside the corresponding boundary 21. In a normal state, the corresponding light-receiving component 622c is set to a state in which it can receive the light beam or a state in which it cannot receive the light beam, and this state is defined as a "predetermined state." If an electronic component 20a with an inaccurate orientation has some non-corresponding contours 21a protruding from the boundary 21, the path of the light beam irradiation changes, and the light-receiving component 622c detects a predetermined change in state, thereby determining that the orientation of the electronic component 20a is inaccurate. Based on the detection result of the light-receiving component 622c, the orientation filter 610c controls its sorting air nozzle 611c to either blow air into the supply chute 510 or turn it off. Specifically, if the light-receiving component 622c detects a light beam when the electronic component 20 / 20a passes through this orientation filter 610c, the orientation filter 610c controls the sorting air nozzle 611c to turn off. On the other hand, if the light-receiving component 622c does not detect a light beam, the orientation filter 610c controls the sorting air nozzle 611c to blow air. The control to blow air and the control to turn air off here refer to the operation of blowing air on or off at a specific time after the electronic component 20 / 20a passes through the orientation filter 610c (i.e., at the time when the corresponding electronic component 20 / 20a passes through the sorting air nozzle 611c). The sorting air nozzle 611c and the second collection box 722 are respectively disposed on both sides of the supply chute 510. Therefore, when an electronic component 20a detected as having poor orientation by the orientation filter 610c passes through the sorting air nozzle 611c, the sorting air nozzle 611c can blow the electronic component 20a into the second collection box 722.

[0038] Furthermore, the posture sorting device 600 may be provided with a pair of light-emitting component 621d and light-receiving component 622d to detect a jam in the transport of electronic components 20. The light beam of this light-emitting component 621d is arranged within a boundary 21 corresponding to the outline of the electronic components 20, and each electronic component 20 output through the supply chute 510 intermittently blocks the light beam. On the other hand, if the light-receiving component 622d detects that the light beam is continuously blocked, it can be confirmed that the transport of electronic components 20 is jammed. If a jam in the transport of electronic components 20 is detected, further corresponding elimination measures (e.g., stopping the machine) can be implemented.

[0039] The electronic component inspection machine of the present invention improves supply efficiency by assisting manual work with the tray conveying device 100.
