Description

Technical Field

[0001] The utility model relates to a mechanism for generating driving force on a skid and a spraying production line adopting the skid. Background Art

[0002] With the popularization of automated production technology, assembly lines combined with automated robots are widely used in production sites, especially in sites with relatively harsh production environments, such as production processes like spraying (painting) and sandblasting.

[0003] To facilitate production operations on components, several skids are generally placed on the assembly line, and then products are hung on the skids. In this way, more products can be placed, and at the same time, the products can be arranged in the height space, with the surface to be operated facing the robot, which is more convenient for operation.

[0004] However, the skid moves along with the assembly line, which results in the brackets and hanging racks on the general skid being fixed structures. After the product is placed on the skid in a certain posture and flows along with the production line, it is handed over to the robot for operation. For some products with complex curved surfaces and other working surfaces located inside the brackets, the robot cannot operate them, so they need to be reloaded and operated again, thus reducing the production efficiency and increasing the flow process of the production line.

[0005] To improve production efficiency, for complex products or complex operation requirements, the brackets on the skid often need to perform certain actions and changes according to the needs of production operations, so that the components on the above devices can be adjusted in posture and position, thus facilitating the operation of the robot. For example, the flipping mechanism for a spraying line with the Chinese patent publication number CN215507385U, a lifting column with the Chinese patent publication number CN111957473A, and a lifting skid with the Chinese patent publication number CN116140096A; but for such mechanisms, since the brackets on the skid need to perform actions, workers or robots need to operate the handles on them to achieve the actions; or a dedicated driving power source is required to be docked with the mechanism on the skid to drive the brackets to perform actions.

[0006] For existing skids, an additional power source is required to achieve actions; but in actual production, especially in harsh production conditions such as spraying and sandblasting, first, workers are not allowed to enter, so it is not convenient for manual operation; second, special tools such as spray guns are installed at the operating ends of automated robots, and it is also not convenient to operate the handles; and a dedicated power source needs to be accurately docked with the skid to perform operations. Especially for those transmitting rotational power, if there is a deviation, it will result in transmission failure and the equipment is easily damaged.

[0059] The following further elaborates on the detailed implementation manners of the present utility model in conjunction with the accompanying drawings.

[0060] As Figure 1 shown, the driving force generation mechanism for the skid of the present utility model can be applied to a spraying production line, especially in the spraying operation area. On the conveyor line 1, several skids 2 are conveyed. Columns are provided on the skids 2, and several layers of product brackets 3 are installed through the columns. The product brackets 3 are movable (liftable or rotatable) brackets; several automated robots 4 are provided in the operation area of the conveyor line 1. The product brackets 3 on the skids 2 need to be changed in the operation area to facilitate the operation of the robots 4; therefore, the driving force generation mechanism for the skid of the present utility model is provided. Specifically, it includes a driving device 5 installed outside the conveyor line 1 and a productivity device 6 installed on the skid 2 and moving synchronously with the skid 2; the driving device 5 is a fixed component, and the productivity device 6 is a moving component. The productivity device 6 moves on the conveyor line 1 with the skid 2 and contacts the driving device 5, converts the force of the conveyor line 1 driving the skid 2 into the displacement and driving force of the sliding table in the productivity device 6, and then transmits it through the transmission device, causing the product bracket 3 to change.

[0061] As Figure 2 、 Figure 3 shown, a specific implementation manner of the driving device 5 is given; the driving device 5 is a horizontally arranged frame, preferably installed and fixed through a bracket 51. A horizontally arranged guiding frame 52 is provided on the upper part of the bracket 51. The height of the guiding frame 52 is slightly higher than the height of the conveyor line 1 to be close to the height of the base of the skid 2 and flush with the productivity device 6; a guiding surface is provided on the side of the guiding frame 52 close to the conveyor line 1, specifically including a productivity driving surface 53, a holding driving surface 54, and a force unloading driving surface 55; the productivity driving surface 53, the holding driving surface 54, and the force unloading driving surface 55 are continuously connected surfaces, and preferably a transition, such as a transition arc, is provided at the connection to make the change process smoother.

[0062] In this embodiment, the driving surface for generating power 53 and the driving surface for releasing power 55 are inclined planes that are inclined with respect to the conveying direction of the conveying line 1, while the holding driving surface 54 is a flat surface parallel to the conveying direction of the conveying line 1.

[0063] As Figure 4 shown, the basic external shape of the power generating device 6 is given; it includes a fixed frame 61, a sliding table 62, a driving wheel 63, a slide rail 64, and a slider 65; the fixed frame 61 is fixed on the base of the skid 2 and serves as a support; a sliding table 62 that can slide relative to the fixed frame 61 is provided on the fixed frame 61; preferably, a driving wheel 63 is provided outside the sliding table 62, and the driving wheel 63 is in direct contact with the guiding surface of the driving device 5, and then moves along with the guiding surface, converting the sliding friction into the rolling motion of the driving wheel 63, thereby reducing the frictional force and directly generating a driving force to drive the sliding table 62 to move.

[0064] The sliding table 62 preferably moves linearly. To ensure the reliable stability of the movement, a linear sliding component is provided between the sliding table 62 and the fixed frame 61, that is, slide rails 64 are respectively provided on both sides of the fixed frame 61, sliders 65 are provided on the slide rails 64, and the sliders 65 on both sides are connected to the sliding table 62, so that the sliding table 62 performs a linear motion under the limitation of the slide rails 64 and the sliders 65; of course, only one set of slide rails 64 and sliders 65 can also be provided.

[0065] The power generating device 6 of the present utility model can transmit the driving force through a driving rope, and transmit the driving force to the product support 3 through the driving rope to drive the product support 3 to change.

[0066] The driving rope 66 can be directly fixed on the sliding table 62, and the movement of the sliding table 62 drives the movement of the driving rope 66.

[0067] Furthermore, as Figure 5 shown, the specific implementation manner of the first embodiment of the power generating device 6 is given; the movement of the sliding table 62 transmits the driving force through the driving rope 66; but fixed pulleys are provided inside the fixed frame 61, namely a first fixed pulley 661 and a second fixed pulley 662. The first fixed pulley 661 is located at the front end of the fixed frame 61, and the driving rope 66 passes around the first fixed pulley 661, and the wrapping angle reaches 180°, so the steering is realized, and the movement direction and the force transmission direction of the driving rope 66 are both turned by 180°. And the second fixed pulley 662 is located at the rear end of the fixed frame 61, and the driving rope 66 passes around the second fixed pulley 662, and the wrapping angle is 90°, so the steering is realized, and the movement direction and the force transmission direction of the driving rope 66 are turned by 90°, converting the horizontal movement into a vertical movement, which is convenient for upward transmission to the product support 3.

[0068] Using the driving rope, it is possible to arrange and turn more conveniently.

[0069] Figure 5 The power generating device 6 shown is Figure 2 , Figure 3 When the driving device 5 shown is used in combination, it can refer to Figure 6 The driving wheel 63 rests against the inclined surface of the force-generating driving surface 53. At this time, the slide 2 and the force-generating device 6 move forward under the transportation of the conveyor line 1. The inclined surface of the force-generating driving surface 53 generates a thrust on the driving wheel 63, so that the driving wheel 63 drives the sliding table 62 to move inward, thereby driving the driving rope 66 to generate an outward and downward pulling force.

[0070] like Figure 7 As shown, another specific implementation of the driving device 5 is given; the guide surface of the guide frame 52 is no longer the surface facing the direction of the conveyor line 1, but the surface facing away from the conveyor line 1, or a groove for the driving wheel 63 to roll. At this time, the driving wheel 63 is convexly mounted on the top or bottom of the sliding table 62, and the fixed frame 61 extends above or below the area where the guide surface of the driving device 5 is located; when the driving force generating mechanism of the sliding sled of the utility model is working, the driving wheel 63 contacts the guide surface facing away from the conveyor line 1, or enters the groove and contacts the guide surface facing away from the conveyor line 1, and the guide surface generates an outward thrust on the driving wheel 63, so that the driving wheel 63 drives the sliding table 62 to move outward, and can also drive the driving rope 66 to generate an outward and downward pulling force.

[0071] In fact, as long as the driving wheel 63 contacts the guide surface, especially the inclined surface of the force-generating driving surface 53, the forward movement of the slide 2 and the force-generating device 6 under the transportation of the conveyor line 1 will be changed through the inclined surface, and the driving wheel 63 will drive the sliding table 62 to move perpendicular to the conveyor line 1, and then transmitted through the driving rope 66 (pulling outward and downward, or releasing the rope inward and upward), driving the product bracket 3 to change.

[0072] By setting the force-generating driving surface 53, the driving wheel 63 of the force-generating device 6 contacts it to generate driving force; therefore, generally speaking, the entrance end of the force-generating driving surface 53 is close to the conveyor line 1, and the exit end of the force-generating driving surface 53 is far away from the conveyor line 1, and the driving force is generated through displacement.

[0073] At the same time, a retaining driving surface 54 is also provided, and the driving wheel 63 of the force-generating device 6 contacts it and no additional displacement occurs, but the position of the force-generating driving surface 53 away from the end is maintained, so that the changed state of the product support 3 is maintained; therefore, generally speaking, the retaining driving surface 54 remains straight and away from the conveyor line 1.

[0074] Finally, a force-unloading driving surface 55 is provided, and the driving wheel 63 of the force-generating device 6 contacts it to generate a reverse driving force, or offset the gravity that restores the initial state, so that the product support 3 slowly restores the initial state; therefore, generally speaking, the entrance end of the force-unloading driving surface 55 is far from the conveyor line 1, and the exit end of the force-unloading driving surface 55 is close to the conveyor line 1. Finally, when the driving wheel 63 completely leaves, there is no driving force and displacement anymore.

[0075] Preferably, the force-generating device 6 does not protrude from the base plane of the sled 2 to avoid collision with other components outside the conveyor line 1 and affect operational safety; in this way, the guide surface of the driving device 5 needs to extend into the base of the sled 2.

[0076] The arrangement of the guide surfaces of the above-mentioned drive device 5, the force-generating driving surface 53, the retaining driving surface 54, and the force-unloading driving surface 55 are not fixed combinations. According to the specific action requirements of the product bracket 3, the force-generating driving surface 53+retaining driving surface 54+force-generating driving surface 53+retaining driving surface 54+force-unloading driving surface 55 can be combined, that is, there are two action processes, and then they are restored at one time; or the force-generating driving surface 53+retaining driving surface 54+force-unloading driving surface 55+retaining driving surface 54+force-unloading driving surface 55 are combined, that is, they are first moved in place once, and then partially restored through the force-unloading driving surface 55, and then finally restored after the operation.

[0077] In particular, the maintaining driving surface 54 and the unloading driving surface 55 are not necessary. For example, after the force generating device 6 drives the product support 3 via the force generating driving surface 53, the conveyor line 1 can be paused to maintain the changed state of the product support 3 for operation. Without the unloading driving surface 55, the force generating device 6 can also lose support instantly and recover.

[0078] The driving device 5 and the force generating device 6 are both installed horizontally, so the displacement generated by the sliding table 62 is also horizontal displacement. The driving rope 66 connecting the sliding table 62 needs to go around the second fixed pulley 662, turn 90 degrees, and then pass upward to the position of the product bracket 3 for driving.

[0079] like Figure 8 As shown, a lifting device 7 can also be provided at the rear side of the force generating device 6 to directly convert the displacement generated by the force generating device 6 into a vertical displacement. The external structure of the lifting device 7 is basically the same as that of the force generating device 6, and also includes a fixed frame and a sliding platform. For the purpose of distinction, they are named vertical frame 71 and lifting platform 72 respectively; the vertical frame 71 is vertically fixed to the rear end of the fixed frame 61, or fixed to the base of the sled 2, to play a supporting role; the vertical frame 71 is provided with a lifting platform 72 that can slide up and down relative to the vertical frame 71, and the lifting platform 72 is connected to the sliding platform 62 through a transmission device to achieve synchronous movement.

[0080] A linear sliding component is also provided between the lifting platform 72 and the vertical frame 71. In this embodiment, slide rails 74 are respectively provided on both sides of the vertical frame 71, and sliders 75 are provided on the slide rails 74. The sliders 75 on both sides are connected to the lifting platform 72, so that the lifting platform 72 makes a linear motion in the vertical direction under the limitation of the slide rails 74 and the sliders 75. Of course, only one set of slide rails 74 and sliders 75 can also be provided.

[0081] A rigid connecting rod 73 can be provided on the lifting platform 72 and is connected to the driving component of the product support 3 through the connecting rod 73 to achieve transmission and driving.

[0082] The connection between the lifting platform 72 and the sliding platform 62 can be a flexible connection, that is, they are connected by a driving rope, as Figure 9 shown. The structure of the power generating device 6 is the same as Figure 5 that. A third fixed pulley 76 is provided at the top of the vertical frame 71. After the driving rope 66 is deflected by the second fixed pulley 662, it then winds around the third fixed pulley 76, and the wrapping angle is 180°. Therefore, the deflection is realized again, so that the moving direction of the driving rope 66 and the direction of the transmitted force are deflected by 180°. The downward pulling force is converted into an upward lifting force. Finally, the end of the driving rope 66 is connected to the lifting platform 72. The sliding platform 62 drives the lifting platform 72 to perform synchronous lifting and lowering movements through the driving rope 66.

[0083] In the above embodiment, the driving rope 66 is a flexible connection to realize the transmission of force and displacement, and can be deflected by a fixed pulley. In practical applications, the same flexible transmission can also be realized through a chain and sprocket structure.

[0084] Furthermore, the connection between the lifting platform 72 and the sliding platform 62 can be a rigid-flexible connection; as Figure 10 shown, a number of steel balls 67 are provided between the lifting platform 72 and the sliding platform 62, and the steel balls 67 form a string of steel balls. The fixed frame 61 and the vertical frame 71 are connected together, and a chamber for accommodating the steel balls 67 and allowing the steel balls 67 to move is provided inside both of them. The chambers of both are connected and form a horizontal chamber and a vertical chamber. A transition arc surface 77 is provided at the connection of the two chambers. The steel balls 67 are filled in the chamber. The sliding platform 62 extends into the chamber of the fixed frame 61 and contacts the horizontal end of the string of steel balls. And the lifting platform 72 also extends into the chamber of the vertical frame 71 and contacts the vertical end of the string of steel balls. When the driving wheel 63 is acted on by the driving device 5 and drives the sliding platform 62 to move, it is transmitted to the lifting platform 72 through the string of steel balls, and then the connecting rod 73 is driven to lift and lower by the lifting platform 72.

[0085] In the above embodiment, in addition to forming a steel bead string through the steel ball 67, the rigid-flexible connection can also use a chain. The chain links are rigid bodies, but the chain as a whole has a certain flexibility and can smoothly pass through the transition arc surface 77 to convert the horizontal force into vertical force, and finally drive the connecting rod 73 to perform lifting and lowering movements.

[0086] In the above embodiment, the driving device 5 and the force generating device 6 are both arranged horizontally, which can save space of the sled 2, especially the height space, which can be used to set the product support 3.

[0087] In particular, the driving device 5 and the force generating device 6 can also be arranged vertically, so that the force generating device 6 directly generates a driving force in a vertical direction to drive the product support 3. At this time, the force generating driving surface 53 of the driving device 5 is also close to the conveyor line 1 at the entry end and far away from the conveyor line 1 at the exit end, and the force generating device 6 generates a driving force through the position difference.

[0088] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments.
