Description

Technical Field

[0001] The utility model relates to the technical field of surface coating, in particular to a toggle steering device used in a coating production line. Background Art

[0002] Painting production lines usually use accumulation chain conveyor lines to transport large workpieces, and transport large workpieces from the upstream position of the production line to the downstream position according to the process. The process equipment or treatment pools / tanks passed through are commonly surface cleaning, spray degreasing, electrophoresis, electroplating, surface powder spraying / surface painting, curing heating, etc. Because large workpieces have a large load and need to go through many surface coating processes, and often need to be coated separately on multiple surfaces of large workpieces. Usually, manual or robot is set at the accumulation station of the accumulation chain conveyor line to transfer the workpieces to be processed entering the accumulation station, so that the workpieces are grabbed from the current accumulation chain conveyor line and transferred to another accumulation chain conveyor line. For large workpieces that need to be sprayed on multiple sides, it is necessary to set up manual or robot transfer at multiple positions corresponding to the multiple working surfaces of the workpiece, and special workpiece surfaces need to be grasped during the transfer process. The positions of manual workers and robot installation need to be arranged according to the requirements of the different working surfaces of the workpiece, and manual workers can only stand at the working surface of special workpieces that can be grasped. If the designated grasping position for large workpieces cannot be set at the accumulation station of the accumulation chain conveyor line, manual workers cannot work. The layout requirements for the accumulation chain conveyor line are relatively high and the constraints are relatively large. When large workpieces transported on the accumulation chain conveyor line arrive at the accumulation station for accumulation, the spacing between large workpieces is small, and only a single robot can be placed at the transfer position. The robot has a fast beat and cannot grasp all workpieces, which is inefficient. Utility Model Content

Detailed implementation manners

[0030] It is easily understandable that, according to the technical solution of the present utility model, without changing the substantial spirit of the present utility model, those of ordinary skill in the art can propose various structural ways and implementation manners that can be mutually replaced. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present utility model, and should not be regarded as the whole of the present utility model or regarded as a limitation or restriction on the technical solution of the present utility model.

[0031] An embodiment of the utility model provides a toggle steering device 100 for a coating production line, wherein the coating production line includes an accumulation chain conveyor line suitable for conveying workpieces, and the toggle steering device 100 is arranged at the accumulation station of the accumulation chain conveyor line, so that when the accumulation trolley of the accumulation chain conveyor line carries the coating tool 200 to the accumulation station for parking and accumulation, the toggle steering device 100 is suitable for toggling the workpiece and rotating the coating tool 200 by a preset angle, so that the workpiece carried by the coating tool 200 is rotated from one working surface to another working surface by a preset angle, so that a transfer robot arranged at a transfer station between two accumulation chain conveyor lines can grab the workpiece from one accumulation chain conveyor line and transfer it to another accumulation chain conveyor line, and continue to perform coating operations on the other working surface of the workpiece. It should be noted that the accumulation chain conveyor line usually includes a frame, a chain track arranged on the frame, a conveyor chain that can be movably arranged on the chain track along the chain track, a driving unit for driving the conveyor chain to move, a load-bearing track arranged on the frame and located below the chain track, and an accumulation trolley that can be movably arranged on the load-bearing track along the load-bearing track. Among them, the accumulation trolley is usually rotatably mounted with a coating tool 200, and the coating tool 200 carries a workpiece. When the accumulation trolley moves to the accumulation station on the load-bearing track, since the conveyor chain and the accumulation trolley are powered off at the accumulation station (usually the pusher head on the conveyor chain is disengaged from the pusher head on the accumulation trolley), the accumulation trolley usually stops at the accumulation station for accumulation, waiting for other power units to intervene and push the accumulation trolley to continue to move along the load-bearing track and leave the accumulation station. The structure and principle of the relevant accumulation chain conveyor line have been found in the prior art. Here, only the technology related to this case is briefly described, and the rest will not be repeated.

[0032] according to Figures 1 to 2 As shown, the toggle steering device 100 includes a support frame 10, a toggle member 20 and a relay drive unit 30. The support frame 10 is fixedly hoisted on the frame (not shown in the figure) of the accumulation chain conveyor line, and the toggle member 20 is movably arranged on the support frame 10. The relay drive unit 30 includes a first drive mechanism 31 and a second drive mechanism 32. The toggle member 20 is relay-driven by the first drive mechanism 31 and the second drive mechanism 32 to rotate a preset angle, so that the toggle member 20 completes the toggle steering operation of the coating tool 200, so that the workpiece carried on the coating tool 200 is rotated from one working surface to another working surface, which is convenient for the robot to grasp and transfer the workpiece in the next step. Since the toggle steering device 100 is installed on the frame as a whole, it is usually located in the upper space of the coating production line. A plurality of toggle steering devices 100 and a plurality of transfer robots can be arranged along the travel path of the accumulation chain conveyor line, so as to facilitate the transfer operation of multiple workpieces at the same time, which not only has high transfer efficiency, but also has high space utilization.

[0033] according toFigures 3 to 5 As shown, the toggle member 20 is movably arranged on the support frame 10 through the movable assembly 40. The movable assembly 40 includes a first sliding plate 41 and a second sliding plate 42 which are relatively slidably arranged and move in opposite directions. The second sliding plate 42 is movably arranged on the support frame 10. The toggle member 20 is rotatably arranged on the first sliding plate 41 through a rotating shaft 23. The rotating shaft 23 has a rotating axis 231. A limiting groove 411 is arranged on the first sliding plate 41. A toggle portion 21 is arranged at one end of the toggle member 20, and a limiting portion 22 is arranged at the other end opposite to the toggle member 20. The limiting portion 22 is limitedly matched with the limiting groove 411. The first driving mechanism 31 is transmission-connected with the first sliding plate 41 and is configured to be suitable for driving the first sliding plate 41 to move. The second driving mechanism 32 is transmission-connected with the second sliding plate 42 and is configured to be suitable for driving the second sliding plate 42 to move. In this embodiment, a first sliding module 43 is arranged between the first sliding plate 41 and the second sliding plate 42, and the first sliding module 43 includes a first slide rail 431 fixedly arranged on the second sliding plate 42 and extending along the length direction of the support frame 10, and a first slider 432 slidably arranged on the first slide rail 431 and fixed to the first sliding plate 41. A second sliding module 44 is arranged between the second sliding plate 42 and the support frame 10, and the second sliding module 44 includes a second slide rail 441 fixedly arranged on the support frame 10 and extending along the length direction of the support frame 10, and a second slider 442 slidably arranged on the second slide rail 441 and fixed to the second sliding plate 42. The first driving mechanism 31 and the second driving mechanism 32 are both cylinders. In other embodiments, the first sliding module 43 and the second sliding module 44 can also be a matching structure of a slider and a slide groove. The first driving mechanism 31 and the second driving mechanism 32 can also use motors, screw rods and other structures, which are not specifically limited.

[0034] In this embodiment, there are multiple toggle members 20, a part of the multiple toggle members 20 is arranged on one side of the second sliding plate 42 along the length direction of the second sliding plate 42, and another part of the multiple toggle members 20 is arranged on the other side opposite to the second sliding plate 42 along the length direction of the second sliding plate 42. There are two first sliding plates 41, and multiple limiting grooves 411 are opened on the two first sliding plates 41. The multiple limiting grooves 411 correspond to the limiting parts 22 of the multiple toggle members 20, and a synchronous connecting rod 412 is connected between the two first sliding plates 41. In other embodiments, the number of toggle members 20 can be set to at least one, two, or more than two, so as to realize the synchronous steering operation of one workpiece, two workpieces, and more than two batches of workpieces, without specific limitation.

[0035] according to Figures 6 to 8As shown, when the first driving mechanism 31 operates, when the first driving mechanism 31 pushes the first sliding plate 41 to move relative to the second sliding plate 42 along the first direction, the limiting portion 22 of the toggling member 20 will move along the limiting groove 411 on the first sliding plate 41, so that the toggling member 20 rotates around the rotation axis 231 along the first rotation direction (i.e., the clockwise direction) from the first position by a first angle to the second position. Then when the second driving mechanism 32 operates, the second driving mechanism 32 pulls the second sliding plate 42 to move relative to the first sliding plate 41 along the second direction opposite to the first direction. The limiting portion 22 of the toggling member 20 will move along the limiting groove 411 of the first sliding plate 41 and the rotating shaft 23 of the toggling member 20 will also move along with the second moving plate, so that the toggling member 20 continues to rotate around the rotation axis 231 along the first rotation direction from the second position by a second angle to the third position.

[0036] It should be noted that when the toggling member 20 is in the first position, the included angle between the toggling member 20 and the support frame 10 is 45°. When the toggling member 20 rotates from the first position by the first angle to the second position, the included angle between the toggling member 20 and the support frame 10 is 90°. When the toggling member 20 rotates from the second position by the second angle to the third position, the included angle between the toggling member 20 and the support frame 10 is 135°. The first angle and the second angle are equal and both are 45°. That is, the actual rotation angle of the toggling member 20 is 90°, which can realize the toggling member 20 to rotate the workpiece by 90°, so that the workpiece rotates from one working surface to another working surface perpendicular thereto. In other embodiments, the stroke of the first driving mechanism 31 and the second driving mechanism 32 can also be extended or shortened, so that when the toggling member 20 is in the first position, the included angle between the toggling member 20 and the support frame 10 can be set between 30° and 45°. When the toggling member 20 is in the second position, the included angle between the toggling member 20 and the support frame 10 can be set between 90° and 120°. When the toggling member 20 is in the third position, the included angle between the toggling member 20 and the support frame 10 can be set between 135° and 150°. And the first angle and the second angle can be equal and be between 45° and 60°, or the second angle is greater than the first angle, which can make the toggling member 20 toggle the workpiece to rotate a preset angle to realize the turning operation between different working surfaces of the workpiece, and the specific details are not limited.

[0037] The technical scope of the present utility model is not limited to the content in the above specification. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present utility model, and these deformations and modifications should all fall within the protection scope of the present utility model.
