Detailed Implementation
[0022] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0023] Please refer to Figure 2 This utility model provides a ring-shaped workpiece conveying and positioning device 100, including a conveying mechanism 10, an adjusting component 20 and a positioning component 30 disposed on the conveying mechanism 10. The conveying mechanism 10 is used to convey a ring-shaped workpiece 200, so as to... Figure 2 The X-axis direction shown is the first direction, and the Y-axis direction is the second direction. The first direction is the same as the width direction of the conveying mechanism 10, and the second direction is the same as the length direction of the conveying mechanism 10.
[0024] Please refer to Figure 2 , Figure 3 and Figure 4 The adjustment assembly 20 includes two drive cylinders 21 disposed opposite to each other on the conveying mechanism 10. The two drive cylinders 21 are distributed in pairs about the central axis in the width direction of the conveying mechanism 10. The output end of the drive cylinders 21 is provided with a positioning plate 22. The drive cylinders 21 are used to drive the positioning plate 22 to push the annular workpiece 200 to move. By setting the adjustment assembly 20, the drive cylinders 21 drive the positioning plate 22 to push the annular workpiece 200 to move until the annular workpiece 200 is distributed in pairs about the central axis in the width direction of the conveying mechanism 10. This achieves the positioning of the annular workpiece 200 before the robot arm clamps it in the next step, thereby improving the conveying efficiency of the annular workpiece 200.
[0025] Please refer to Figure 2 and Figure 4 Furthermore, the positioning plate 22 is provided with positioning posts 23, and the two positioning posts 23 cooperate with each other to position the annular workpiece 200. The side wall of the positioning post 23 is an arc-shaped surface, and the setting of the positioning post 23 further facilitates the clamping of the outer peripheral surface of the annular workpiece 200.
[0026] Please refer to Figure 2 and Figure 5 The positioning assembly 30 includes a lifting cylinder 31 and a support frame 32 disposed at the output end of the lifting cylinder 31. The support frame 32 has a first connecting rod 34 and a second connecting rod 35 arranged in a cross shape. A positioning block 36 is disposed at the intersection of the first connecting rod 34 and the second connecting rod 35. The positioning block 36 is located on the central axis in the width direction of the conveying mechanism 10, and the distance from the end of the first connecting rod 34 to the end of the second connecting rod 35 to the center of the positioning block 36 is equal. A rotary motor 33 is connected to the positioning block 36 and is fixedly connected to the support frame 32. The rotary motor 33 drives the first connecting rod 34 and the second connecting rod 35 to rotate, and the lifting cylinder 31 drives the first connecting rod 34 and the second connecting rod 35 to rise and fall until they contact the annular workpiece 200.
[0027] During positioning, the lifting cylinder 31 drives the first connecting rod 34 and the second connecting rod 35 to move until they contact the annular workpiece 200. If the distance from the contact point of the first connecting rod 34 with the annular workpiece 200 to the center of the positioning block 36, and the distance from the contact point of the second connecting rod 35 with the annular workpiece 200 to the center of the positioning block 36 are equal, that is, the center of the second positioning block 36 coincides with the center of the annular workpiece 200, then the annular workpiece 200 is considered to be symmetrically distributed about the central axis of the width direction of the conveying mechanism 10. Then, the rotary motor 33 drives the first connecting rod 34 and the second connecting rod 35 to rotate. If the distance from the contact point of the first connecting rod 34, the second connecting rod 35, and the annular workpiece 200 to the center of the positioning block 36 are equal at different angles, then it is further determined whether the center of the annular workpiece 200 coincides with the center of the positioning block 36.
[0028] Optionally, the distance from the contact point between the first link 34 and the annular workpiece 200 to the center of the positioning block 36, and the distance from the contact point between the second link 35 and the annular workpiece 200 to the center of the positioning block 36 can be measured by a displacement sensor. The displacement sensor is existing technology and will not be described in detail in this embodiment.
[0029] It is understood that in this embodiment, the initial positions of the first link 34, the second link 35 and the positioning block 36 are above the frame 11. When the drive cylinder 21 adjusts the position of the annular workpiece 200, the center of the annular workpiece 200 and the center of the positioning block 36 are located on the same line set along the first direction.
[0030] Please refer to Figure 2 and Figure 6 The conveying mechanism 10 includes a frame 11 and a positioning section 12 and a conveying section 13 disposed on the frame 11, as well as a drive motor 15. The positioning section 12 is closer to the drive cylinder 21 than the conveying section 13. The positioning section 12 includes a plurality of first rollers 121 and a plurality of second rollers 122 distributed in pairs. The first rollers 121 and the second rollers 122 are distributed in pairs about the central axis between the two drive cylinders 21, and a through groove 123 for the positioning block 36 to pass through is spaced between the first rollers 121 and the second rollers 122. The conveying section 13 includes a plurality of third rollers 131, and the first rollers 121, the second rollers 122 and the third rollers 131 are connected in pairs.
[0031] After the annular workpiece 200 is placed into the positioning section 12, it is conveyed by the first roller 121 and the second roller 122. After the position is adjusted by the drive cylinder 21 and the center position is determined by the positioning block 36, it is conveyed to the next process by the third roller 123.
[0032] The first roller 121, the second roller 122, and the third roller 131 are all coaxially connected to gears 14, and adjacent gears 14 are connected by chains. A drive motor 15 drives the first roller 121, the second roller 122, and the third roller 131 to rotate synchronously via a timing belt 16 and a chain. Specifically, in this embodiment, two drive motors 15 are arranged in pairs in the first direction.
[0033] Please refer to Figure 6 The frame 11 is also equipped with a lifting cylinder 40, and the output end of the lifting cylinder 40 is equipped with a limiting post 41. The lifting cylinder 40 is used to drive the limiting post 41 to lift the annular workpiece 200. Specifically, in this embodiment, the lifting cylinder 40 is located between the two third rollers 131. When it is necessary to pause the conveying of the annular workpiece 200, the lifting cylinder 40 drives the limiting post 41 to lift the annular workpiece 200 until it is disengaged from the third roller 131.
