Description

Technical Field

[0001] The utility model relates to the production and assembly fields of automobiles, in particular to a high-precision stacking column for a white body welding production line. Background Art

[0002] At present, in a white body welding production line of an automobile, when storing and transporting parts, stacking columns are required to support the parts. A plurality of stacking columns jointly enclose a shape matching the outer contour of the parts, and then the parts are placed on the stacking columns. Each part is supported by a plurality of stacking columns together. In order to save space and facilitate the robot to pick up parts, a plurality of parts are stacked and distributed in the longitudinal direction, and they are respectively supported by the supporting mechanisms arranged on the stacking columns.

[0003] In order to realize the stacked placement of workpieces, the supporting mechanism on the stacking column needs to have the following characteristics: First, in the non-working state, it can allow the parts to pass through smoothly to ensure that the parts can be placed starting from the bottom layer; Second, when all the supporting mechanisms below have placed parts, the current supporting mechanism can stably and reliably support the parts.

[0004] For traditional stacking columns, due to structural defects, parts are often stuck when they should not be supported, and cannot work properly when they should support the parts, resulting in the inclination of the parts, and thus the automated picking operation of the robot cannot be realized.

[0005] Therefore, there is a need for a method or device that can solve the above problems now. Summary of the Invention

[0006] The utility model is proposed to solve the above-mentioned deficiencies existing in the prior art, and provides a high-precision stacking column for a white body welding production line, which has a simple structure, ingenious design, reasonable layout, smooth and reliable movement, and can stably support parts.

[0007] The technical solution of the utility model is: A high-precision stacking column for a white body welding production line, including a bottom plate 1, characterized in that: a longitudinal bracket 2 is arranged on the bottom plate 1, two symmetrically distributed baffles 3 are arranged on one side of the longitudinal bracket 2, a working gap is formed between the two baffles 3, and a plurality of connecting rod flap mechanisms 4 are arranged in the baffles 3.

[0008] A plurality of the link flap mechanisms 4 are equally spaced longitudinally. The link flap mechanism 4 includes a positioning flap 6 rotatably supported on a longitudinal bracket 2 by a rotating shaft 5. The positioning flap 6 is divided into a front half 7 and a rear half 8 with the rotating shaft 5 as the boundary. A counterweight 9 is connected to the rear half 8. The link flap mechanism 4 further includes a limit post 14 fixedly connected to the longitudinal bracket 2. The limit post 14 is located above the front half 7. A link 10 is also connected between adjacent link flap mechanisms 4.

[0009] A plurality of the link flap mechanisms 4 are numbered sequentially from bottom to top. The link 10 is disposed between the nth and the (n - 1)th link flap mechanisms 4. The top end of the link 10 is rotatably connected to the rear half of the positioning flap 6 in the nth link flap mechanism 4 through an upper connecting shaft, and the bottom end of the link 10 is rotatably connected to the rear half of the positioning flap 6 in the (n - 1)th link flap mechanism 4 through a lower connecting shaft. And the lower connecting shaft is movably connected in a long groove formed in the link 10.

[0010] For the positioning flap 6 in the lowermost link flap mechanism 4, its front half 7 always protrudes from the baffle 3.

[0011] The link flap mechanism 4 further includes a limit groove 11 formed in the longitudinal bracket 2. The limit groove 11 matches with a limit projection 12 provided at the tail end of the rear half 8.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The high-precision stacking column for a white body welding production line with this structural form has a simple structure, ingenious design and reasonable layout. Aiming at the problems existing in the traditional stacking column during the working process, a special structure is designed. Its nth layer link flap mechanism can maintain a closed state when the (n - 1)th layer link flap mechanism is not working, allowing the workpiece to pass through smoothly. Once the (n - 1)th layer link flap mechanism is in a working state (supporting a workpiece), the nth layer link flap mechanism will be linked with the lower layer mechanism and be in a waiting trigger state. In this way, as long as a workpiece touches the nth layer link flap mechanism, it will change to a working state and support the workpiece. It can realize the sequential placement of workpieces from bottom to top, and the actions are smooth and reliable, capable of achieving stable support. And its manufacturing process is simple and the manufacturing cost is low. Therefore, it can be said that it has multiple advantages and is particularly suitable for popularization and application in this field, and its market prospect is very broad.

[0020] The specific embodiments of the present utility model will be described below in conjunction with the accompanying drawings. As Figures 1 to 6 shown: A high-precision stacking column for a white body welding production line includes a bottom plate 1 as a foundation. A longitudinal bracket 2 is provided on the bottom plate 1. On one side of the longitudinal bracket 2, two symmetrically distributed baffles 3 are provided. The working gap is between the two baffles 3. A plurality of connecting rod flap mechanisms 4 are provided within the baffles 3.

[0021] A plurality of the connecting rod flap mechanisms 4 are equally spaced in the longitudinal direction. The connecting rod flap mechanism 4 includes a positioning flap 6 rotatably supported on the longitudinal bracket 2 by a rotating shaft 5. The positioning flap 6 is divided into a front half part 7 and a rear half part 8 with the rotating shaft 5 as the boundary. A counterweight 9 is connected to the rear half part 8. The connecting rod flap mechanism 4 further includes a limit post 14 fixedly connected to the longitudinal bracket 2. The limit post 14 is located above the front half part 7. A connecting rod 10 is also connected between adjacent connecting rod flap mechanisms 4.

[0022] A plurality of the connecting rod flap mechanisms 4 are numbered sequentially from bottom to top. The connecting rod 10 is provided between the nth and the (n - 1)th connecting rod flap mechanisms 4. The top end of the connecting rod 10 is rotatably connected to the rear half part of the positioning flap 6 in the nth connecting rod flap mechanism 4 through an upper connecting shaft. The bottom end of the connecting rod 10 is rotatably connected to the rear half part of the positioning flap 6 in the (n - 1)th connecting rod flap mechanism 4 through a lower connecting shaft. And the lower connecting shaft is movably connected in a long groove opened on the connecting rod 10.

[0023] For the positioning flap 6 in the lowermost connecting rod flap mechanism 4, its front half part 7 always protrudes from the baffle 3.

[0024] The connecting rod flap mechanism 4 further includes a limit groove 11 opened on the longitudinal bracket 2. The limit groove 11 matches with a limit protrusion 12 provided at the tail end of the rear half part 8.

[0025] The working process of the high-precision stacking column for the white body welding production line in the embodiment of the utility model is as follows: According to the outer contour of the workpiece 13 to be stacked, the number of the stacking columns is determined, and multiple stacking columns are arranged according to the outer contour of the workpiece 13 to ensure that the workpiece 13 can be supported by the link flap mechanism in multiple stacking columns;

[0026] In the initial state, among the second to the nth link flap mechanisms 4 in the same stacking column, since counterweights 9 are arranged on the rear half part 8 of the positioning flap 6, these positioning flaps 6 are in an upturned state. At this time, the edge of the front half part 7 of the positioning flap 6 is located inside the baffle 3 and will not hinder the downward movement of the workpiece 13;

[0027] When the first workpiece 13 is placed into the stacking rack composed of multiple stacking columns, since the positioning flaps 6 in the second to the nth link flap mechanisms 4 are all in the retracted state, the workpiece 13 can directly fall to the first (the lowermost) link flap mechanism 4. Since the front half part of the positioning flap 6 at this position always protrudes from the baffle 3 (the above purpose is achieved by setting the specific position of the limit post 14 matching the positioning flap 6), the edge of the front half part 7 of the positioning flap 6 will protrude from the baffle 3 in the initial state. That is to say, when the workpiece 13 falls to this position, on the positioning flaps 6 in all the lowermost link flap mechanisms 4, the edge of the front half part 7 will support the workpiece 13 from below. When the workpiece 13 presses down the positioning flap 6, the positioning flap 6 will swing around the rotating shaft 5 until the limit protrusion 12 at the end of its rear half part 8 contacts the top edge of the limit groove 11 opened on the longitudinal support 2. Under the action of the limit groove 11, the positioning flap 6 cannot continue to flip or swing. When all the positioning flaps 6 are in this state, they jointly support the workpiece 13;

[0028] When the positioning flap 6 in the first link flap mechanism 4 swings to the horizontal state (i.e., the state of supporting the workpiece 13), its rear half part 8 will push up the link 10 connected to it. After the link 10 is pushed up (since the bottom end of the link 10 is connected to the lower connecting shaft through a long slot, the link 10 can move), it will drive the positioning flap 6 in the second link flap mechanism 4 to swing by a certain angle. At this time, the edge of the front half part 7 of the positioning flap 6 will protrude from the baffle 13. That is to say, at this time, the positioning flap 6 in the second link flap mechanism 4 interferes with the movement track of the next workpiece 13; thus, when the next workpiece is placed into the stacking rack, the workpiece 13 will be blocked and supported by the second link flap mechanism 4, and when the second link flap mechanism acts, it will drive the third link flap mechanism 4 to act through the link 10 on it to support the third workpiece 13;

[0029] After the workpiece 13 on the nth layer is taken away, the positioning flap 6 on this layer swings again under the action of the counterweight 9, and its rear half 8 moves downward. However, since the positioning flap 6 in the link flap mechanism 4 on the (n - 1)th layer is still in a horizontal state (the state of supporting the workpiece 13), it still pushes the positioning flap 6 on the nth layer upward through the link 10. Therefore, the edge of the front half 7 of the positioning flap 6 on the nth layer still protrudes beyond the baffle 3 and is in a ready state to work at any time.
