[0033] See also Figure 1 , Figure 2 and Figure 3 A bolt arrangement and placement plate includes a linear module 1, a mounting portion 2, a placement portion 3, a first drive 4, a sliding portion 5 and a second drive 6.

[0034] The linear module 1 is a prior art, and can be a screw type or a synchronous belt type linear module 1. The installation slide block 1a of the linear module 1 is horizontally slidable.

[0035] The mounting part 2 is mounted on the mounting slider 1a of the linear module 1. In this way, the mounting part 2 is driven by the linear module 1 to slide horizontally and change its position. When it is in one position, it is used to receive the bolts transmitted by the vibration plate, and when it is in another position, it is used for the robot to take away the bolts.

[0036] The mounting portion 2 includes a top plate 2a, a bottom plate 2b and a plurality of optical axes 2c fixed therebetween. Accordingly, the mounting portion 2 is mounted on the mounting slider 1a of the linear module 1, that is, the bottom plate 2b is fixedly connected to the mounting slider 1a.

[0037] See also Figure 4 The placement part 3 is rotatably connected to the top plate 2a of the mounting part 2 around a vertical axis. Specifically, a bearing seat is installed on the top plate 2a, and a rotating shaft is fixedly connected to the bottom surface of the placement part 3, and the rotating shaft is connected to the bearing in the bearing seat.

[0038] See also Figure 2 and Figure 3 The placement portion 3 is also provided with a plurality of groups of placement holes 3a in a circular array uniformly around the axis. In the attached drawings, four groups of placement holes 3a are used as an example. The placement holes are stepped, that is, the bolts are transmitted from the vibration plate and fall into the placement holes, the screw rods of the bolts enter the small holes below the placement holes, and the nuts of the bolts enter the large holes above the placement holes.

[0039] The first drive 4 is disposed on the top plate 2a of the mounting portion 2, and drives the placement portion 3 to rotate the same angle each time, which is equal to the angle between two adjacent groups of placement holes 3a (taking four groups of placement holes 3a as an example, the angle is 90 degrees).

[0040] Optionally, the first drive 4 is a first servo motor.

[0041] The sliding part 5 is slidably connected to the optical axis 2c of the mounting part 2. Specifically, each optical axis 2c is equipped with a linear bearing, and the sliding part 5 is fixedly connected to these linear bearings. The sliding part 5 is also fixedly provided with an ejector rod 5a that can pass through the top plate 2a at a position corresponding to each placement hole 3a, and the top plate 2a is provided with an ejector hole for the ejector rod 5a to pass through at a position corresponding to the ejector rod 5a.

[0042] See also Figure 2 Optionally, a plurality of optical axes 2c correspond to the area between two adjacent groups of placement holes 3a in sequence. This can conveniently avoid interference between the optical axis 2c and the ejector rod 5a, and conveniently set the positions of the optical axis 2c and the ejector rod 5a.

[0043] The second drive 6 is disposed on the bottom plate 2b of the mounting portion 2, and drives the sliding portion 5 to slide up and down. Through the second drive 6, the ejector rod 5a is in a first state lower than the placement portion 3 or in a second state entering the placement hole 3a of the placement portion 3. In this way, in the first state, the ejector rod 5a will not interfere with the rotation of the placement portion 3, and in the second state, the ejector rod 5a is responsible for ejecting the bolt in the placement hole 3a upward.

[0044] In combination with the two states required for the ejection rod 5a, the second drive 6 may be a cylinder.

[0045] See also Figure 3Optionally, there are two sliding parts 5, and all ejector rods 5a are divided into two groups and arranged on the two sliding parts 5. There are also two second drivers 6, which act on the two sliding parts 5 respectively. In this way, the space between the two sliding parts 5 is reserved, which is convenient for the arrangement of the first driver 4, and the two sliding parts 5 avoid interference with the first driver 4 during the sliding process.

[0046] In this way, the bolts are sent into the placement holes 3a through the vibration plate and the material guide track, and after the placement of a group of bolts in the placement holes 3a is completed; the first drive 4 drives the placement part 3 to rotate, and repeats the operation of placing bolts for another group of placement holes 3a; after completing the placement of multiple groups of bolts in the placement holes 3a, the linear module 1 drives the placement part 3 to move to a position for the robot to take away the bolts; after the robot moves to the position corresponding to the placement part 3, the sliding part 5 moves up, and the ejector rod 5a ejects the bolts in all the placement holes 3a, and the bolts enter the multiple clamps on the robot in turn, the clamps clamp the bolts, and the robot moves to take out the bolts.

[0047] For each group of placement hole positions 3a, each group of placement hole positions 3a can be divided into multiple columns (two columns in the figure) along the movement direction of the linear module 1. After the bolts are placed in one column of placement hole positions 3a, the placement part 3 can be moved a certain distance through the linear module 1 to make the next column of placement hole positions 3a enter the corresponding position to receive the bolts sent by the vibration plate.

[0048] See also Figure 5 and Figure 6 Optionally, the arrangement and placement plate of the bolts further includes an adjustment mechanism 7. The mounting portion 2 can adjust its position by sliding horizontally relative to the mounting slider 1a. The adjustment mechanism 7 is disposed on the mounting slider 1a and is used to adjust the position of the mounting portion 2 relative to the mounting slider 1a. That is, after a row of placement holes 3a are placed with bolts, the placement portion 3 is moved a certain distance by the adjustment mechanism 7, so that the next row of placement holes 3a enters the corresponding position to receive the bolts sent by the vibration plate.

[0049] Furthermore, the adjustment mechanism 7 includes a cam 7a and a second servo motor 7b. According to the number of columns of a group of placement holes 3a, the cam 7a groove includes a plurality of arc segments with different diameters and a transition segment connecting these arc segments. The mounting portion 2 is provided with a latch 2d that forms a slot pin pair with the cam 7a groove. When the cam 7a rotates one circle, the mounting portion 2 moves intermittently, and the multiple columns of placement holes 3a enter the corresponding positions in turn to receive the bolts sent by the vibration plate.
