Embodiment approach 1

[0022] (Embodiment 1) A workpiece support system according to Embodiment 1 will be described. First, the configuration of the workpiece support system will be described. figure 1 It is a perspective view of a vehicle welding assembly line employing the workpiece support system according to the first embodiment. like figure 1 As shown, in a vehicle welding assembly line 70 , a self-propelled conveyor loops along line 70 and has a workpiece support device 10 mounted on the self-propelled conveyor. Predetermined steps are assigned to each predetermined position in line 70 . The self-propelled conveyor on which the workpiece supporting device 10 is mounted goes through a cycle of a series of steps: from a vehicle type switching step 71 through a workpiece setting step 72, a welding / deposition assembling step 73, and a finished product removal step 74 Go to the vehicle type switching step 71 for the next vehicle type. In these steps, predetermined operations are performed by de...

Embodiment approach 2

[0070] (Embodiment 2) Next, Embodiment 2 will be described. Embodiment 2 is a workpiece support device 10 mounted on a rotary table. Figure 7 is a plan view illustrating the workpiece support system according to Embodiment 2. like Figure 7 As shown, the workpiece support system 2 in Embodiment 2 is provided with a rotary table 83 . The turntable 83 has, for example, a disk shape. The upper surface of the turntable is divided into two parts, wherein the workpiece supporting device 10a is mounted on one part, and the workpiece supporting device 10b is mounted on the other part.

[0071] A plurality of, for example, four robots are installed around the turntable 83 . In the clockwise direction viewed from above, the robot 501 for the vehicle type switching step 71, the robot 503a for the first welding / bonding assembly step 73, the robot 503b for the second welding / bonding assembly step 73 and a robot 504 for the finished product removal step 74 are arranged around the rota...

Embodiment approach 3

[0073] (Embodiment 3) Next, Embodiment 3 will be described. Embodiment 3 relates to the support portion 42 .

[0074] Figure 8 is a view illustrating a supporting portion of a workpiece supporting device in a workpiece supporting system according to Embodiment 3. FIG. like Figure 8 As shown, the support portion 42 of the support body 40 of the workpiece support device 10 is a combination of a support portion 42a, a support portion 42b, and a support portion 42c. Each support portion 42 has a cylindrical shape.

[0075] The support portion 42 c is fixed to the post 41 of the support body 40 . A recess is formed in the upper surface of the support portion 42c. This recess serves as a spherical bearing 44 . A spherical body 45 is attached to the bottom surface of the bearing portion 42b. The spherical body 45 of the support part 42b fits in the spherical bearing 44 of the support part 42c. Thus, the support portion 42b can be rotated relative to the support portion 42c ...

Abstract

A workpiece support system includes: a workpiece support device that supports a workpiece by a support body having a support that comes in contact with the workpiece; and a robot that is separately provided outside the workpiece support device and moves the support, wherein the support is configured to be movable within a predetermined range and lockable at an arbitrary position, and wherein, by grasping a part of the locked support body, the robot unlocks the support and moves the unlocked support according to the shape of the workpiece.

Description

technical field [0001] The present invention relates to a workpiece support system, in particular a workpiece support system for supporting a workpiece, for example during welding of a vehicle or the like. Background technique [0002] Workpiece supports that support workpieces, eg during welding of vehicles etc., are usually manufactured specifically for each type of workpiece, ie for each type of vehicle. In such a dedicated workpiece support device, the position of the support portion that supports the workpiece is fixed. However, if a movable support is used, a plurality of types of workpieces can be supported by one workpiece supporting device. Japanese Patent Application Publication No. 2014-129033 discloses a workpiece support device (assembly device) that supports a workpiece by a support portion movable in the X-axis direction, the Y-axis direction, and the Z-axis direction. [0003] The workpiece supporting device disclosed in JP 2014-129033 A has a complicated s...
