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 Art

[0002] Conventional electronic component inspection machines generally include a single turntable and a plurality of lenses arranged corresponding to the turntable. Electronic components are placed on the turntable one by one, driven by the turntable to rotate, and pass in front of each lens. Each lens acquires an image of the electronic component passing from a different direction, and inspects the appearance of each electronic component based on this.

Summary of the Invention

Problems to be Solved by the Invention

[0003] Conventional electronic component inspection machines have the problem that it is inconvenient when transporting electronic components. As a result, electronic components are often placed on the turntable in a tilted state. When an electronic component is placed on the turntable in a tilted state, false judgments may occur in the inspection based on the acquired image, or it may become impossible to accurately determine whether the appearance meets the standard.

[0004] Furthermore, if the electronic components that have passed the inspection are placed in an incorrect posture after being collected, they are likely to jam inside the rails when being transported on the transport rails.

[0022] Figure 1 is a schematic perspective view of an electronic component inspection machine according to one embodiment of the present invention. Figure 2 is a top view of an electronic component inspection machine according to one embodiment of the present invention. Referring to Figures 1 and 2, one embodiment of the present invention provides an electronic component inspection machine that includes a tray transport device 100, a receiving device 200, an appearance inspection device 400, a supply device 500, and an orientation sorting device 600.

[0023] Figure 3 is a schematic perspective view of the tray transport device of an electronic component inspection machine according to one embodiment of the present invention. Figures 4 to 6 are schematic diagrams showing the usage state of the tray transport device of an electronic component inspection machine according to one embodiment of the present invention. Referring to Figures 1 to 6, the tray transport device 100 is for loading trays 10 on which multiple electronic components 20 are placed and loading empty trays 10. The receiving device 200 loads the electronic components 20 in the trays 10 into the visual inspection device 400 for visual inspection, the supply device 500 outputs the electronic components 20 that have passed the visual inspection from the visual inspection device 400 to the next station, and the orientation sorting device 600 detects whether the orientation of the output electronic components 20 is correct or not according to the request of the next station.

[0024] Referring to Figures 3 to 6, the tray transport device 100 includes a trolley 110, a first platform 121, a second platform 122, a first fork section 131, and a second fork section 132. The first fork section 131 is positioned to be vertically movable in accordance with the first platform 121, and the first fork section 131 is capable of translation between the first platform 121 and the trolley 110. Specifically, the first fork section 131 is positioned on a first lift mechanism 141, the first lift mechanism 141 is positioned on a first slide rail 151, the first slide rail 151 extends between the first platform 121 and the trolley 110, and the vertical movement of the first lift mechanism 141 and the translation on the first slide rail 151 can be driven by components such as a pneumatic cylinder or a linear actuator. The second fork section 132 is positioned to be vertically movable in accordance with the second platform 122, and is capable of translation between the second platform 122 and the trolley 110. Specifically, the second fork section 132 is positioned on the second lift mechanism 142, the second lift mechanism 142 is positioned on the second slide rail 152, the second slide rail 152 extends between the second platform 122 and the trolley 110, and the lifting and lowering operation of the second lift mechanism 142 and the translational movement 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 bogie 110 in the translational direction 111. Furthermore, the first slide rail 151 and the second slide rail 152 are arranged parallel to each other and perpendicular to the translational direction 111 of the bogie 110. However, the present invention is not limited to the above-described embodiment.

[0026] Referring to Figures 4 to 6, the worker first places a tray 10 on which multiple electronic components 20 are placed on the first platform 121, arranging the electronic components 20 in rows within the tray 10, and at least one tray 10 can be placed on the first platform 121. The first fork section 131 moves along the first slide rail 151 and rises to lift the tray 10 when it reaches below a predetermined tray 10. Next, the first fork section 131 moves along the first slide rail 151 to load the tray 10 onto the trolley 110. Next, the first fork section 131 lowers to release the tray 10. The trolley 110 moves the tray 10, aligning the electronic components 20 in the tray row by row for the receiving device 200, and loads them into the receiving device 200. Once all the electronic components 20 in tray 10 have been loaded into the receiving device 200 and tray 10 is empty, the trolley 110 moves tray 10 and aligns it with the second slide rail 152. The second fork section 132 moves along the second slide rail 152 and rises to lift tray 10 when it reaches below a predetermined tray 10. Next, the second fork section 132 moves along the second slide rail 152 to unload tray 10 onto the second platform 122. Then, the second fork section 132 lowers to release tray 10. The aforementioned tray transport device 100 facilitates the loading and unloading process of tray 10 via the first platform 121 and the second platform 122, and plays a role in smoothly connecting human work processes and automated work processes by machines.

[0027] Figure 7 is a schematic perspective view of the receiving device of an electronic component inspection machine according to one embodiment of the present invention. Figures 8 and 9 are schematic diagrams showing the usage state of the receiving device of an electronic component inspection machine according to one embodiment of the present invention. Referring to Figures 1 to 2 and Figures 7 to 9, the receiving device 200 includes a receiving chute 210, a push rail 220, and a push rod 230. The receiving chute 210 has an inlet end 211 and an outlet end 212 at both ends. The inlet end 211 of the receiving chute 210 is positioned corresponding to the other side of the translational direction 111 of the trolley 110. The push rod 230 is pivotally attached to the push rail 220 so as to be able to translate along the longitudinal direction of the receiving chute 210. Specifically, the push rail 220 comprises a rail 221 and a slider 222 positioned on the rail 221, the slider 222 is able to translate along the rail 221, and the push rod 230 is pivotally attached to the 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 longitudinal direction, and the push rod 230 is positioned corresponding to the entrance end 211 of the receiving chute 210. The push rod 230 is provided with a magnetic adsorption member 240 and an elastic member 250. The magnetic adsorption member 240 and the elastic member 250 are positioned on opposing sides of the push rod 230 in the longitudinal direction of the receiving chute 210, the magnetic adsorption member 240 adsorbs the slider 222, and the elastic member 250 is connected to the slider 222 in a pre-stretched state.

[0028] Referring to Figures 1, 7, and 8, the trolley 110 moves the tray 10 in a parallel manner, aligning the electronic components 20 in the tray 10 row by row onto the receiving chute 210 and 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 transported one by one to the visual inspection device 400 from the exit end 212 of the receiving chute 210. A vibration motor can be selectively connected to the receiving chute 210, and vibrating the receiving chute 210 can accelerate the movement of the electronic components 20 inside.

[0029] Referring to Figures 8 and 9, if a jam occurs while the electronic component 20 is being pushed through the receiving chute 210 or 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 adsorption member 240 and detaches, stopping the movement of pushing the electronic component 20. In addition, the elastic member 250 retracts the push rod 230 away from the electronic component 20, preventing the push rod 230 from pressing against or damaging the electronic component 20.

[0030] Referring to Figures 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 disc or ring-shaped structure and is provided with a mounting surface 411. A predetermined rotation path 401 is formed along the mounting surface 411, surrounding the rotation center of the rotating platform 410. These image acquisition units 430 are arranged to surround the rotation center of the rotating platform 410, and each is located close to the rotating platform 410. In addition, the exit end 212 of the receiving chute 210 is located corresponding to one point on the edge of the rotating platform 410. Specifically, the exit end 212 of the receiving chute 210 is configured to correspond to the predetermined rotation path 401 so as to place the electronic components 20 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 sequentially pass through each image acquisition unit 430. Each image acquisition unit 430 is positioned facing a predetermined rotation path 401 from a different direction, and acquires images of the electronic component 20 as it passes through the predetermined rotation path 401. These image acquisition units 430 can each acquire images of the electronic component 20 passing from different directions.

[0031] Figures 10 and 11 are schematic diagrams of a guide assembly for an electronic component inspection machine according to one embodiment of the present invention. Referring to Figures 1-2, 10 and 11, a guide assembly 300 can be selectively positioned between a receiving device 200 and a visual inspection device 400. This guide assembly 300 ensures that the electronic components 20 pushed out from the receiving device 200 are precisely positioned on a predetermined rotation path 401. The guide assembly 300 is suspended above a rotating platform 410 corresponding to the exit end 212 of the receiving chute 210. The guide assembly 300 includes at least one guide block 310a, 310b, each of which is selectively positioned on either one or both sides of the predetermined rotation path 401. Each guide block 310a, 310b has a guide surface, all of which are oriented toward the predetermined rotation path 401. In this embodiment, these guide surfaces include a pair of primary guide surfaces 311a and secondary guide surfaces 311b. A pair of primary guide surfaces 311a are positioned opposite each other on both sides of a predetermined rotation path 401, defining a tapered passage that narrows toward the direction of rotation of the rotating platform 410. This allows electronic components 20 that have fallen from the receiving chute 210 onto the mounting surface 411 to be guided toward the predetermined rotation path 401. A secondary guide surface 311b is positioned following the primary guide surfaces 311a in the direction of rotation of the rotating platform 410 and is located on one side of the predetermined rotation path 401. The secondary guide surface 311b guides the center of the electronic component 20 located on the predetermined rotation path 401 to align with the predetermined rotation path 401. This improves the accuracy of the inspection results by the visual inspection device 400. Specifically, the secondary guide surface 311b has a radius of curvature slightly smaller than the arc surface of the predetermined rotation path 401. Therefore, after the electronic component 20 temporarily contacts the secondary guide surface 311b, it is pushed toward the predetermined rotation path 401.

[0032] Figure 12 is a schematic perspective view of an appearance filter 710 of an electronic component inspection machine according to one embodiment of the present invention. Referring to Figures 1-2 and Figure 12, the electronic component inspection machine of the present invention may further include an appearance filter 710 that is linked to an 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 recovery box 712. The first air nozzle 711 is positioned toward the rotating platform 410 and is linked 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 blow air onto the rotating platform 410 or turn it off. The control of blowing air and turning it off here refers to the control of blowing air or turning it off at a specific time (i.e., when the electronic component 20 passes the first air nozzle 711) after the appearance inspection device 400 has detected an electronic component 20. Specifically, the first air nozzle 711 and the first recovery box 712 are arranged on both sides of a predetermined rotation path 401. Therefore, when an electronic component 20 that the visual inspection device 400 has determined to be unacceptable passes through the first air nozzle 711, the first air nozzle 711 can blow the electronic component 20 into the first recovery box 712.

[0033] To accommodate different rejection conditions and detection errors, multiple appearance filters (710, 710a, 710b) are arranged along a predetermined rotating path 401 to classify and recover rejected electronic components 20. Each appearance filter (710, 710a, 710b) includes a first air nozzle (711, 711a, 711b) and a first recovery box (712, 712a, 712b). The first air nozzles (711, 711a, 711b) are positioned toward the rotating 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 permanently open state. The appearance inspection device 400 controls the first air nozzle 711b to turn off only when it detects that a passing electronic component 20 has passed through the first air nozzle 711b. This prevents defective electronic components 20 from passing through the appearance filter 710 due to operational errors in the appearance filter (710, 710a, 710b).

[0034] Figures 13 and 14 are schematic perspective views of a supply device for an electronic component inspection machine according to one embodiment of the present invention. Referring to Figures 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 vertically, thereby reducing the overall volume of the electronic component inspection machine. One end of the supply chute 510 is positioned corresponding to another part 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 arranged sequentially from the last image acquisition unit 430 to the supply chute 510. The push wheel 520 is suspended above the mounting surface 411 and is positioned across a predetermined rotation path 401 and the supply chute 510. This allows the electronic component 20 on a predetermined rotation path 401 to be pushed along the outer edge of the push wheel 520 and moved to 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 positioned toward the supply chute 510 and assists in pushing the electronic component 20 on the predetermined rotation path 401 into the supply chute 510.

[0035] Figures 15 and 16 are schematic perspective views of the orientation sorting device for an electronic component inspection machine according to one embodiment of the present invention. Figures 17 to 19 are schematic diagrams showing the orientation sorting device for an electronic component inspection machine according to one embodiment of the present invention in use. Referring to Figures 1 to 2 and Figures 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 a corresponding at least one second recovery box 722. In this embodiment, all of these sorting air nozzles correspond to the same second recovery box 722.

[0036] Referring to Figures 16 to 18, in the orientation filters (610a, 610b) of the first embodiment, each sorting air nozzle (611a, 611b) is positioned at a predetermined location corresponding to a boundary 21 in a specific direction on the contour of the electronic component 20. The sorting air nozzles (611a, 611b) are set to be open at all times. Specifically, one sorting air nozzle 611a of the first embodiment is positioned at a predetermined location corresponding to one horizontal boundary 21 on the contour of the electronic component 20, as shown in Figure 17. The other sorting air nozzle 611b of the first embodiment is positioned at a predetermined location corresponding to the upper boundary 21 on the contour of the electronic component 20, as shown in Figure 18. As shown in Figures 17 and 18, in the case of an electronic component 20a with an incorrect orientation, some non-corresponding contours 21a protrude from the predetermined location on the boundary 21 in a specific direction. When this 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 blown into the second collection box 722.

[0037] Referring to Figure 19, in the attitude filter 610c of the second aspect of this embodiment, the sorting air nozzle 611c is positioned toward the path 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 positioned at predetermined locations on the boundary 21 corresponding to a specific direction in the contour of the electronic components 20 / 20a. The light-emitting component 621c emits a light beam toward the supply chute 510, and this light beam is positioned to pass just outside the corresponding boundary 21. In the 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 it, and this state is defined as the "predetermined state". In the case of an electronic component 20a with an incorrect orientation, if some non-matching contours 21a protrude from the boundary 21, the irradiation path of the light beam changes, and the light-receiving component 622c detects a change in a predetermined state, thereby revealing that the orientation of the electronic component 20a is incorrect. Based on the detection result of the light-receiving component 622c, the orientation filter 610c controls its sorting air nozzle 611c to blow air onto the supply chute 510 or turn it off. Specifically, when the electronic component 20 / 20a passes through the orientation filter 610c, if the light-receiving component 622c detects a light beam, the orientation filter 610c controls the sorting air nozzle 611c to turn it 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 onto it. The control of blowing air and turning it off, as referred to here, refers to the operation of blowing air or turning it off at a specific time after the electronic component 20 / 20a has passed through the attitude filter 610c (i.e., when the electronic component 20 / 20a in question passes through the sorting air nozzle 611c). The sorting air nozzle 611c and the second recovery box 722 are located on both sides of the supply chute 510, respectively. Therefore, when an electronic component 20a detected by the attitude filter 610c as having a poor attitude passes through the sorting air nozzle 611c, the sorting air nozzle 611c can blow this electronic component 20a into the second recovery box 722.

[0038] Furthermore, the orientation sorting device 600 may also include a pair of light-emitting components 621d and light-receiving components 622d to detect jams in the transport of electronic components 20. The light beam of the light-emitting component 621d is positioned within a boundary 21 corresponding to the contour of the electronic component 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 blocking of the light beam continues, it can be confirmed that the transport of the electronic components 20 is jammed. If a transport jam of the 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 assists manual work with a tray transport device 100 and improves supply efficiency. Furthermore, inspection accuracy can be improved by accurately placing the electronic components 20 using a receiving device 200 and a guide assembly 300. In addition, subsequent work is facilitated by organizing the electronic components 20 output by the orientation sorting device 600.
