Description

工件外觀檢查機之整列裝置Arrangement device of workpiece appearance inspection machine

本發明有關一種工件外觀檢查機之整列裝置，尤指一種降低工件飛料機率之整列裝置設計者。 The present invention relates to an alignment device of a workpiece appearance inspection machine, and in particular to a designer of an alignment device that reduces the probability of workpieces flying.

按，TWI480540B(CN103204375B/JP6009167B)揭露一種工件的外觀檢查裝置，其具備：搬送六面體形狀工件之線性給料器，使來自線性給料器的工件移載而搬送的搬送台，使來自線性給料器的工件移載至搬送台上進行排列之移載排列手段，保持工件於搬送台的保持手段，攝影工件的六面之攝影手段，以及真空抽吸搬送台與排列導件之間的間隙的真空抽吸單元；移載排列手段具有被設於線性給料器與搬送台之間的無振動部，及排列工件的排列導件，排列導件包含從平面上看成直線狀的導引面，保持手段可由配置在搬送台的下方的導體，並對導體施加直流電壓產生靜電感應所構成；其中，如圖1所示，導體11施加直流電壓致使搬送台12受到產生靜電感應作用，搬送台頂部與底部會感應不同極性，同理落至搬送台的工件13頂部與底部也會感應不同極性，工件13遂因靜電感應作用而吸附於搬送台12，再經由排列導件14與真空吸力的配合，將剛落至搬送台12而稍微歪斜的工件13進行整列，讓後續的工件外觀檢查工作可以順利進行。 Press, TWI480540B (CN103204375B/JP6009167B) discloses an appearance inspection device for workpieces, which is provided with: a linear feeder that transports hexahedral-shaped workpieces, a transfer platform that transfers the workpieces from the linear feeder, and a transfer platform that transfers the workpieces from the linear feeder. Transfer and arrangement means for transferring workpieces to the transfer table and arranging them, holding means for keeping the workpieces on the transfer table, photography means for photographing six sides of the workpiece, and vacuum for vacuuming the gap between the transfer table and the arrangement guide The suction unit; the transfer and arrangement means have a vibration-free part provided between the linear feeder and the transfer table, and an arrangement guide for arranging the workpieces. The arrangement guide includes a guide surface that is linear when viewed from a planar surface, and holds The means may be composed of a conductor arranged under the transport platform, and applying a DC voltage to the conductor to generate electrostatic induction; wherein, as shown in Figure 1, the conductor 11 applies a DC voltage, causing the transport platform 12 to be subjected to electrostatic induction, and the top and bottom of the transport platform will Different polarities are induced. Similarly, the top and bottom of the workpiece 13 dropped to the transfer table will also sense different polarities. The workpiece 13 is adsorbed to the transfer table 12 due to electrostatic induction, and then through the cooperation of the arrangement guide 14 and vacuum suction, the workpiece 13 will just drop. The slightly skewed workpieces 13 that arrive at the transfer table 12 are aligned so that the subsequent workpiece appearance inspection can be carried out smoothly.

然而，為了使工件13更緊密吸附在搬送台12上，通常會將對導體11施加較大的直流電壓，也因為工件13與排列導件14都屬於金屬導體，工件13在觸碰到排列導件14的瞬間會因感應起電，將圖示的搬送台12/工件13/排列導件 14頂部標示為負極而底部為正極進行說明，工件13頂部負電會瞬間被帶走，致使工件13帶正電，乃與排列導件14底部同性相斥，工件13會有飛料的機率；因此，對於利用靜電感應配合排列導件與真空吸力進行工件整列工作之先前技術，為了克制工件13飛料的問題，可利用排列導件14下方的真空吸力而拉住工件13，但整列後真空吸力也須停止，讓工件13脫離排列導件14，工件13還是會有飛料的機率，且會因工件13越小造成飛料的機率越高。 However, in order to make the workpiece 13 more tightly adhered to the conveying table 12, a larger DC voltage is usually applied to the conductor 11. Also, because the workpiece 13 and the arrangement guide 14 are both metal conductors, the workpiece 13 will not move when it touches the arrangement guide. The workpiece 14 will be electrified by induction at the moment, and the transfer table 12/workpiece 13/arrangement guide shown in the figure will The top of 14 is marked as the negative electrode and the bottom as the positive electrode for explanation. The negative charge on the top of the workpiece 13 will be taken away instantly, causing the workpiece 13 to be positively charged, which is the same as the bottom of the arrangement guide 14 and repels it. There will be a chance of flying materials on the workpiece 13; therefore Regarding the previous technology of using electrostatic induction in conjunction with alignment guides and vacuum suction to align workpieces, in order to overcome the problem of flying materials on the workpieces 13, the vacuum suction under the alignment guide 14 can be used to pull the workpieces 13, but the vacuum suction will not be used after alignment. It is necessary to stop and let the workpiece 13 separate from the arrangement guide 14. The workpiece 13 will still have a probability of flying materials, and the smaller the workpiece 13, the higher the probability of flying materials.

本發明之主要目的，欲解決先前技術工件飛料機率高之問題，而具有降低工件飛料機率之功效。 The main purpose of the present invention is to solve the problem of high probability of workpiece flying in the prior art and to have the effect of reducing the probability of workpiece flying.

本發明之另一目的，則具有降低真空抽吸耗能之功效。 Another object of the present invention is to reduce vacuum suction energy consumption.

為達上述功效，本發明之技術特徵，包括有：一搬送轉盤，設置於工件外觀檢查機之機架，承接來自線性給料器的工件而予以搬送；一承靠塊，相對該線性給料器之出料端而設置於該機架，該承靠塊懸空位於該搬送轉盤之盤緣內側上方，該承靠塊具有一承靠面，該承靠面朝向該搬送轉盤之內側；一真空抽吸單元，設置於該承靠塊與該搬送轉盤之間，而於該承靠面相對該搬送轉盤徑向的切線點之前側下方產生吸力；一相斥塊，相對該承靠面設置於該機架，該相斥塊懸空位於該搬送轉盤上方，該相斥塊與該承靠塊之間形成整列間距；以及一導電塊，相對該承靠塊與該相斥塊設置於該機架，該導電塊懸空位於該搬送轉盤下方，施加電壓於該導電塊令該搬送轉盤、該承靠塊與該相斥塊皆產生靜電感應，致使該承靠塊與該相斥塊的底部皆相對該搬送轉盤的頂部產生相吸之靜電力，該承靠塊與該相斥塊之間則會產生相斥之靜電力；藉此，自該線性給料器落下的工件亦因靜電感應作用而吸附於該搬送轉盤頂面，工件被 該搬送轉盤逐一搬送至該承靠塊，工件觸碰到該承靠塊的瞬間會因感應起電讓工件頂部的電荷瞬間被帶走，致使工件成為帶電體而電性與該承靠塊/該相斥塊底部的電性相同；於是，工件被搬送至該承靠面相對該搬送轉盤徑向的切線點之前，該真空抽吸單元的吸力將工件吸往該承靠面進行整列，當工件被搬送至該承靠面相對該搬送轉盤徑向的切線點之後，該搬送轉盤之靜電吸力所產生的徑向摩擦力讓工件脫離該承靠塊而整列於預期的搬送軌跡。 In order to achieve the above effect, the technical features of the present invention include: a transfer turntable, which is installed on the frame of the workpiece appearance inspection machine to receive the workpieces from the linear feeder and transport them; a supporting block relative to the linear feeder. The discharging end is arranged on the frame, and the supporting block is suspended above the inner side of the rim of the conveying turntable. The supporting block has a supporting surface, and the supporting surface faces the inner side of the conveying turntable; a vacuum suction A unit is arranged between the supporting block and the transfer turntable, and suction is generated below and in front of the supporting surface relative to the radial tangent point of the transporting turntable; a repulsive block is provided on the machine relative to the supporting surface. rack, the repulsive block is suspended above the transfer turntable, and a full row spacing is formed between the repelling block and the supporting block; and a conductive block is arranged on the frame relative to the supporting block and the repelling block, the The conductive block is suspended below the transfer turntable. Applying voltage to the conductive block causes the transfer turntable, the support block and the repulsion block to generate electrostatic induction, causing the bottoms of the support block and the repulsion block to face the transfer turntable. The top of the linear feeder generates an electrostatic force of attraction, and the support block and the repulsive block generate a repulsive electrostatic force; thereby, the workpieces falling from the linear feeder are also attracted to the transfer turntable due to electrostatic induction. On the top surface, the workpiece is The transfer turntable transports the support block one by one. The moment the workpiece touches the support block, the charge on the top of the workpiece is instantly taken away due to induction electrification, causing the workpiece to become a charged body and electrically connected to the support block/ The electrical properties of the bottoms of the repulsive blocks are the same; therefore, before the workpiece is transported to the tangent point of the radial direction of the supporting surface relative to the transfer turntable, the suction force of the vacuum suction unit will suck the workpieces to the supporting surface for alignment. After the workpiece is transported to the radial tangent point of the support surface relative to the transport turntable, the radial friction force generated by the electrostatic attraction of the transport turntable causes the workpiece to break away from the support block and align on the expected transport trajectory.

此外，該相斥塊與該承靠塊之間的相對位置可調整。該真空抽吸單元的吸力由前往後逐漸縮小。 In addition, the relative position between the repelling block and the supporting block is adjustable. The suction power of the vacuum suction unit gradually decreases from front to back.

The present invention includes: a transfer turntable 20, which is installed on the frame 21 of the workpiece appearance inspection machine to receive and transport the workpieces 23 from the linear feeder 22; a supporting block 30. It is arranged on the frame 21 relative to the discharge end of the linear feeder 22. The supporting block 30 is suspended above the inner side of the rim of the transfer turntable 20. The supporting block 30 has a supporting surface 31. The supporting surface 31 faces the inside of the conveying turntable 20; a vacuum suction unit 40 is disposed between the supporting block 30 and the conveying turntable 20, and the radial tangent of the supporting surface 31 to the conveying turntable 20 Down the side before point T (upstream) To generate suction, the vacuum suction unit 40 can form/set an air extraction channel 41 between the bottom surface of the supporting block 30 and the top surface of the transfer turntable 20, and connect the air extraction channel 41 to the air extraction pump 42, and make The suction force of the vacuum suction unit 40 gradually decreases from the front (upstream) to the back (downstream); a repulsive block 50 is provided on the frame 21 relative to the supporting surface 31, and the repelling block 50 is suspended on the transfer turntable. 20 above, a whole row spacing 51 is formed between the repelling block 50 and the supporting block 30. The repelling block 50 is arranged on the frame 21 through a cantilever 52. The cantilever 52 has an elongated hole relative to the frame 21. 521, the repulsive block 50 has an elongated hole 501 relative to the cantilever 52, so that the relative position between the repelling block 50 and the supporting block 30 can be adjusted; and a conductive block 60, relative to the supporting block 30 The repulsive block 50 is disposed on the frame 21 , and the conductive block 60 is suspended below the transfer turntable 20 .

藉此，請參閱圖4、圖5所示，施加電壓於該導電塊60令該搬送轉盤20、該承靠塊30與該相斥塊50皆產生靜電感應，致使該承靠塊30與該相斥塊50的底部皆相對該搬送轉盤20的頂部產生相吸之靜電力，該承靠塊30與該相斥塊50之間則會產生相斥之靜電力；於是，自該線性給料器22落下的工件23亦因靜電感應作用而吸附於該搬送轉盤20頂面，工件23被該搬送轉盤20逐一搬送至該承靠塊30，工件23觸碰到該承靠塊30的瞬間會因感應起電讓工件23頂部的電荷瞬間被帶走，致使工件23成為帶電體而電性與該承靠塊30/該相斥塊50底部的電性相同。 4 and 5 , applying a voltage to the conductive block 60 causes the transfer turntable 20 , the supporting block 30 and the repelling block 50 to generate electrostatic induction, causing the supporting block 30 and the phase repelling block 50 to generate electrostatic induction. The bottoms of the repelling blocks 50 generate an electrostatic force that attracts each other relative to the top of the transfer turntable 20 , and a repulsive electrostatic force generates between the supporting block 30 and the repelling block 50 ; thus, from the linear feeder 22 The fallen workpieces 23 are also adsorbed on the top surface of the transfer turntable 20 due to electrostatic induction. The workpieces 23 are transported one by one by the transfer turntable 20 to the support block 30. The moment the workpieces 23 touch the support block 30, they will be electrostatically induced. The electricity causes the charge on the top of the workpiece 23 to be instantly taken away, causing the workpiece 23 to become a charged object with the same electrical properties as the electrical properties at the bottom of the supporting block 30 / the repulsive block 50 .

基於如是之構成，工件23會被限制在該相斥塊50與該承靠塊30間所形成之整列間距51進行整列過程；其中，先如圖4所示，工件23被搬送至該承靠面31相對該搬送轉盤20徑向的切線點T之前，工件23於該搬送轉盤20的徑向會受到該搬送轉盤20之靜電吸力所產生的徑向摩擦力F1(忽略工件重量產生的徑向摩擦力)、該承靠塊30的頂推力F2與靜電斥力F3、該真空抽吸單元40的吸力F4與 該相斥塊50的靜電斥力F5，該承靠塊30對工件23的靜電斥力F3與該相斥塊50對工件23的靜電斥力F5會相互抵銷，該真空抽吸單元40的吸力F4只要大於該搬送轉盤20的徑向摩擦力F1，即可將工件23吸往該承靠面31，工件23遂受到該承靠塊30的頂推力F2而進行整列；接著，如圖5所示，當工件23被搬送至該承靠面31相對該搬送轉盤20徑向的切線點T之後，因已不再有該真空抽吸單元40的吸力F4，該承靠塊30對工件23的靜電斥力F3與該相斥塊50對工件23的靜電斥力F5會相互抵銷，工件23乃受到該搬送轉盤20之靜電吸力所產生的徑向摩擦力F1，逐一脫離該承靠塊30而整列於預期的搬送軌跡R。 Based on such a structure, the workpiece 23 will be limited to the entire row spacing 51 formed between the repelling block 50 and the supporting block 30 to perform the alignment process; wherein, as shown in FIG. 4 , the workpiece 23 is transported to the supporting block first. Before the tangent point T of the surface 31 relative to the radial direction of the conveying turntable 20, the workpiece 23 will be subjected to the radial friction force F1 generated by the electrostatic attraction of the conveying turntable 20 in the radial direction of the conveying turntable 20 (ignoring the radial friction force F1 caused by the weight of the workpiece). friction force), the pushing force F2 and the electrostatic repulsion force F3 of the supporting block 30, the suction force F4 and the The electrostatic repulsive force F5 of the repulsive block 50 , the electrostatic repulsive force F3 of the supporting block 30 on the workpiece 23 and the electrostatic repulsive force F5 of the repulsive block 50 on the workpiece 23 will cancel each other out. The suction force F4 of the vacuum suction unit 40 only needs If the radial friction force F1 of the transfer turntable 20 is greater than the radial friction force F1 of the transfer turntable 20, the workpieces 23 can be sucked to the supporting surface 31, and the workpieces 23 will be aligned by the pushing force F2 of the supporting block 30; then, as shown in Figure 5, When the workpiece 23 is transported to the tangent point T in the radial direction of the supporting surface 31 relative to the transport turntable 20 , since there is no longer the suction force F4 of the vacuum suction unit 40 , the electrostatic repulsive force of the supporting block 30 on the workpiece 23 The electrostatic repulsive force F5 of F3 and the repulsive block 50 on the workpiece 23 will cancel each other out. The workpieces 23 will be separated from the supporting block 30 one by one by the radial friction force F1 generated by the electrostatic attraction of the transfer turntable 20 and arranged in the desired direction. The conveying trajectory R.

是以，本發明透過設置相斥塊50抵銷承靠塊30對工件23的靜電斥力，在工件23被搬送至承靠面31相對搬送轉盤20徑向的切線點T之前，真空抽吸單元40對工件23的吸力F4只要大於搬送轉盤20對工件23的徑向摩擦力F1，即可將工件23吸往承靠面31而利用頂推力F2進行整列；而前揭先前技術的真空吸力要大於搬送台(搬送轉盤)的徑向摩擦力加上排列導件(承靠塊)對工件的靜電斥力，也就必須比本發明耗費較大的真空吸力，故本發明具有降低真空抽吸耗能之功效。然而，在工件23被搬送至承靠面31相對搬送轉盤20徑向的切線點T之後，雖已不再有該真空抽吸單元40的吸力F4，但因該承靠塊30對工件23的靜電斥力F3會被該相斥塊50對工件23的靜電斥力F5予以抵銷，工件23利用徑向摩擦力F1脫離該承靠塊30，即可於整列間距51內順利整列於預期的搬送軌跡R，不會飛料，而讓本發明具有降低工件飛料機率之功效。 Therefore, the present invention counteracts the electrostatic repulsive force of the supporting block 30 on the workpiece 23 by arranging the repulsive block 50. Before the workpiece 23 is transported to the tangent point T in the radial direction of the supporting surface 31 relative to the conveying turntable 20, the vacuum suction unit As long as the suction force F4 of 40 on the workpiece 23 is greater than the radial friction force F1 of the transfer turntable 20 on the workpiece 23, the workpiece 23 can be sucked to the supporting surface 31 and aligned using the pushing force F2; while the vacuum suction force of the previous technology requires It is greater than the radial friction force of the conveying table (carrying turntable) plus the electrostatic repulsion of the arrangement guide (supporting block) to the workpiece, which requires a larger vacuum suction force than the present invention. Therefore, the present invention has the ability to reduce vacuum suction consumption. The effect of energy. However, after the workpiece 23 is transported to the tangent point T in the radial direction of the supporting surface 31 relative to the conveying turntable 20, although there is no longer the suction force F4 of the vacuum suction unit 40, due to the impact of the supporting block 30 on the workpiece 23, The electrostatic repulsive force F3 will be offset by the electrostatic repulsive force F5 of the repulsive block 50 on the workpiece 23. The workpiece 23 will use the radial friction force F1 to break away from the supporting block 30, so that the workpiece 23 can be smoothly aligned on the expected transportation track within the entire row spacing 51. R, there will be no flying materials, and the invention has the effect of reducing the probability of workpiece flying materials.

一種工件外觀檢查機之整列裝置，包括有：一搬送轉盤，設置於工件外觀檢查機之機架，承接來自線性給料器的工件而予以搬送；一承靠塊，相對該線性給料器之出料端而設置於該機架，該承靠塊懸空位於該搬送轉盤之盤緣內側上方，該承靠塊具有一承靠面，該承靠面朝向該搬送轉盤之內側；一真空抽吸單元，設置於該承靠塊與該搬送轉盤之間，而於該承靠面相對該搬送轉盤徑向的切線點之前側下方產生吸力；一相斥塊，相對該承靠面設置於該機架，該相斥塊懸空位於該搬送轉盤上方，該相斥塊與該承靠塊之間形成整列間距；以及一導電塊，相對該承靠塊與該相斥塊設置於該機架，該導電塊懸空位於該搬送轉盤下方，施加電壓於該導電塊令該搬送轉盤、該承靠塊與該相斥塊皆產生靜電感應，致使該承靠塊與該相斥塊的底部皆相對該搬送轉盤的頂部產生相吸之靜電力，該承靠塊與該相斥塊之間則會產生相斥之靜電力；藉此，自該線性給料器落下的工件亦因靜電感應作用而吸附於該搬送轉盤頂面，工件被該搬送轉盤逐一搬送至該承靠塊，工件觸碰到該承靠塊的瞬間會因感應起電讓工件頂部的電荷瞬間被帶走，致使工件成為帶電體而電性與該承靠塊/該相斥塊底部的電性相同；於是，工件被搬送至該承靠面相對該搬送轉盤徑向的切線點之前，該真空抽吸單元的吸力將工件吸往該承靠面進行整列，當工件被搬送至該承靠面相對該搬送轉盤徑向的切線點之後，該搬送轉盤之靜電吸力所產生的徑向摩擦力讓工件脫離該承靠塊而整列於預期的搬送軌跡。 An arrangement device for a workpiece appearance inspection machine, including: a transfer turntable, which is installed on the frame of the workpiece appearance inspection machine, to receive workpieces from a linear feeder and transport them; and a supporting block, which is opposite to the discharge of the linear feeder. The end is disposed on the frame, and the supporting block is suspended above the inner side of the rim of the conveying turntable. The supporting block has a supporting surface, and the supporting surface faces the inner side of the conveying turntable; a vacuum suction unit, It is disposed between the supporting block and the conveying turntable, and generates suction force below and in front of the radial tangent point of the conveying turntable relative to the supporting surface; a repelling block is disposed on the frame relative to the supporting surface, The repulsive block is suspended above the transfer turntable, and a full row spacing is formed between the repelling block and the supporting block; and a conductive block is arranged on the frame relative to the supporting block and the repelling block, and the conductive block Suspended below the transfer turntable, applying voltage to the conductive block causes the transfer turntable, the support block and the repulsion block to generate electrostatic induction, causing the bottoms of the support block and the repulsion block to be relative to the top of the transfer turntable An electrostatic force of mutual attraction is generated, and a repulsive electrostatic force is generated between the supporting block and the repulsive block; thereby, the workpieces falling from the linear feeder are also adsorbed on the top surface of the transfer turntable due to electrostatic induction. , the workpieces are transported one by one to the supporting block by the transfer turntable. The moment the workpiece touches the supporting block, the charge on the top of the workpiece is instantly taken away due to induction electrification, causing the workpiece to become a charged body and electrically connected to the supporting block. The electrical properties of the bottom of the supporting block and the repelling block are the same; therefore, the workpiece is transported to the tangent point of the supporting surface relative to the radial direction of the transport turntable, and the suction force of the vacuum suction unit sucks the workpiece to the supporting surface for processing. When the workpieces are transported to the radial tangent point of the support surface relative to the transfer turntable, the radial friction force generated by the electrostatic attraction of the transfer turntable causes the workpieces to break away from the support block and align on the expected transfer trajectory. 如請求項1所述之工件外觀檢查機之整列裝置，其中，該相斥塊與該承靠塊之間的相對位置可調整。 The arrangement device of the workpiece appearance inspection machine as claimed in claim 1, wherein the relative position between the repelling block and the supporting block is adjustable. 如請求項1或2所述之工件外觀檢查機之整列裝置，其中，該真空抽吸單元的吸力由前往後逐漸縮小。 The integrated device of the workpiece appearance inspection machine as described in claim 1 or 2, wherein the suction force of the vacuum suction unit gradually decreases from front to back.
