Abstract

PURPOSE:To perform insertion work in a short time, by providing bright points in three places of a part mounting region while detecting the bright points in the three places through two camera units in a different mounting position and calculating coordinate values in the space. CONSTITUTION:When an assembly hub surface is three-dimensionally displaced, three of the assembly hub bolts 5 provide in their bolt top parts bright points 6 by white paint or the like. The method calculates a position of the hub surface in the space and a rotary angle of the hub bolt 5 only by optically measuring said three points through two sets of camera units. While when the center of the assembly hub surface can be determined, the top part in one of the assembly hub bolts 5 provides the bright point 6 by the white paint or the like. The method, optically measuring this one point by one set of camera unit, calculates the rotary angle of the hub bolt 5. Accordingly, automatization of assembly can be promoted by enabling an insertion material to be optically guided with the bright point 6 serving as the target.

Description

【発明の詳細な説明】 産業上の利用分野 本発明はタイヤホイル等複数個の取付ボルトを有する部
品の自動取付方法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for automatically attaching parts such as tire wheels having a plurality of attachment bolts.

従来の技術 自動車のタイヤホイルは３本又はそれ以上のハブボルト
によって取付けられており、こ取付作業は人力により行
われている。BACKGROUND OF THE INVENTION Tire wheels of automobiles are attached using three or more hub bolts, and this attachment is done manually.

発明が解決しようとする問題点 前述の取付作業を自動化する上での最大の問題は、タイ
ヤホイール側の組付用ハブボルト孔と車体側のハブボル
トを５まく合致させることが次の理由から困難なことで
ある。Problems to be Solved by the Invention The biggest problem in automating the above-mentioned installation work is that it is difficult to match the assembly hub bolt holes on the tire wheel side with the hub bolts on the vehicle body side for the following reasons. That's true.

υ　前輪はフロントアライメントによって組付ハブ面が
三次元に変化しており、独立懸架方式では後輪も含め組
付ハブ面を一定に保持することが出来ない。υ The front wheel assembly hub surface changes three-dimensionally due to front alignment, and independent suspension systems cannot maintain the assembly hub surface constant, including the rear wheel.

２）ホイル回転方向の位置決め並びにその保持が出来な
い。特にＦＲ車の後輪は差動装置を介して結合しており
一層難しい。2) It is not possible to position the wheel in the rotating direction and hold it. In particular, the rear wheels of FR vehicles are connected via a differential, making it even more difficult.

問題点を解決するための手段 タイヤホイル組付用ハブボルトのうち３個のボルト頂部
を他とコントラスト（例；蛍光ペイント塗布）を付け、
２基の撮像装置によって上記３個のボルト頂部を検出し
て空間上の座標値を算出し更にタイヤホイル組付の為の
ホイル回転方向（ホイルのボルト穴〜ハブボルト合せ）
及び移動経路を算出して組付自動化を図るものである。Measures to solve the problem: Paint the tops of three of the hub bolts for tire wheel assembly in contrast with the others (for example, apply fluorescent paint).
Two imaging devices detect the tops of the three bolts, calculate the spatial coordinates, and then calculate the wheel rotation direction for tire wheel assembly (wheel bolt hole - hub bolt alignment).
The system also calculates the movement route to automate assembly.

尚ハブの中心が外部設備（例：ガイｌ−″）によつて決
められる場合はハブボルト１個の頂部にコントラストを
付は且つ１基の撮像装置によってホイル回転方向が決ま
り組付自動化を図ることが出来る。In addition, if the center of the hub is determined by external equipment (e.g. guide l-''), a contrast should be added to the top of one hub bolt, and the direction of wheel rotation should be determined by one imaging device to automate assembly. I can do it.

作用 撮像装置により検出されたノ・プボルトの位置に対応し
てタイヤホイールの孔の位置を決め、タイヤホイールを
ハブボルトに装着する。The position of the hole in the tire wheel is determined in accordance with the position of the knob bolt detected by the action imaging device, and the tire wheel is attached to the hub bolt.

実施例 第１図において、１はタイヤ、２はホイール、３はホイ
ール２のボルト孔、４はノ１プ、５はノ１プボルト、６

輝点である。Embodiment In FIG. 1, 1 is a tire, 2 is a wheel, 3 is a bolt hole of the wheel 2, 4 is a bolt hole, 5 is a bolt hole, and 6 is a bolt hole of the wheel 2.
is a bright spot added to the tip of Porto 5 using white paint, fluorescent ink, etc.

（１）組付ハブ面が三字元に変化している場合、■　組
付用ハブボルト５０３個の頂部に白ペンキ等で輝点６を
付ける。(1) If the assembly hub surface has changed to a three-character shape, ■ Add a bright spot 6 on the top of the 503 assembly hub bolts with white paint.

■　その３点を２基の撮像装置にて光学的に測定するの
みでハブ面の空間上の位置とハブボルト５０回転角度を
算出する。(2) The spatial position of the hub surface and the rotation angle of the hub bolt 50 can be calculated by simply optically measuring those three points using two imaging devices.

（２）組付ハブ面の中心が決められる場合、■　組付用
ハブボルト５の１個の頂部に白ペンキ等で輝点６を付け
る。(2) When the center of the assembly hub surface is determined: ■ Add a bright spot 6 to the top of one of the assembly hub bolts 5 with white paint or the like.

■　その１点を１基の撮像装置にて光学的に測定してハ
ブボルト５０回転角度を算出する。(2) Optically measure that point using one imaging device and calculate the hub bolt 50 rotation angle.

この場合、撮像装置は１基で目的を達成できる。In this case, the purpose can be achieved with one imaging device.

（３）　　製造上の都合で輝点を付する点は必ずしもハ
ブボルト頂部でなくてもたとえばその側部或いは別個の
目標となる特定点でも差支えない。(3) For manufacturing reasons, the point to which a bright spot is attached is not necessarily the top of the hub bolt, but may be, for example, the side thereof or a specific point that is a separate target.

また輝点の数は、３次元型の場合は３点必要であるが、
２次元盤の場合は１点でよい。In addition, the number of bright spots is three in the case of a three-dimensional type, but
In the case of a two-dimensional board, one point is sufficient.

発明の効果 輝点を目標として光学的に挿入物を誘導できるので、短
時間で取付作業を終了できる。Advantages of the Invention Since the insert can be optically guided to the bright spot, the installation work can be completed in a short time.
