[0002] When the buttons on the steering wheel of a car are assembled through automated assembly equipment, the buttons need to be turned over and glued, and then the buttons need to be assembled to the product housing. Commonly used flipping mechanisms usually use a rotating cylinder, or a combination of gears and racks, or a rotating motor to flip the buttons. For example, the clamping and flipping mechanism disclosed in Publication No. CN104355149A uses a rotating cylinder to flip the buttons, and the clamping and flipping manipulator disclosed in Publication No. CN111168711A uses a rack-driven gear to rotate for flipping. The reversible material clamping mechanism disclosed in Publication No. CN114434476A uses a rotating motor to flip the buttons. The above methods cannot achieve precise control of the flipping angle. If the flipping angle is not accurately controlled, it will affect the glue dispensing of the product, and the product is prone to swing after it is flipped into place. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 4 As shown, a preferred embodiment of the utility model proposes an eccentric flipping device, which mainly includes a rotating shaft 15, a flip control plate 10, a flip driving mechanism 5, a deflection member 16, a clamping mechanism 4, a fixed plate 2, a bearing plate 1 and other components. The bearing plate 1 is provided with two pieces, which are vertically fixed on both sides of the bottom of the fixed plate 2 respectively. The rotating shaft 15 passes through the two bearing plates 1 in sequence and is rotatably connected to the bearing plates 1 through a bearing, wherein one end of the bearing is fixedly connected to the flip connecting member 3, and the other end is fixedly connected to the deflection member 16. The clamping mechanism 4 is installed and fixed on the flip connecting member 3. When the deflection member 16 is deflected, it will drive the rotating shaft to rotate, thereby driving the clamping mechanism 4 to flip.

[0025] like Figure 2 As shown, two sliders 12 are arranged on the side of the bearing plate 1 away from the clamping mechanism 4, and the slider 12 is fixedly connected to the bearing plate 1. A slide rail 13 is slidably connected to the slider 12, and the slide rail 13 is fixed on the flip control board 10. A fixed block 8 is also arranged on the flip control board 10 for installing and fixing the flip drive mechanism 5.

[0026] In this embodiment, the flip driving mechanism 5 adopts a cylinder, the output end of the cylinder is connected to the connecting rod 14, and the other end of the connecting rod 14 is hinged to the center of the flip control board 10, and the flip control board 10 is driven by the cylinder to move linearly.

[0027] refer to Figure 4 , Figure 5 A slide groove 101 is provided on the flip control plate 10, and the distribution track of the slide groove 101 is adapted to the deflection track of the deflection member 16. The deflection member 16 deflects around the rotation axis 15 when deflecting, so a pulley 11 is rotatably connected to the other end of the deflection member 16 (i.e., the end away from the rotation axis 15), and the pulley 11 is slidably connected to the slide groove 101. When the flip control plate 10 moves, the pulley 11 slides along the track of the slide groove 101, thereby driving the deflection member 16 to deflect, and then driving the rotation axis 15 to rotate.

[0028] In this embodiment, the distribution trajectory of the slide groove 101 is similar to a “V” shape, and the pulley 11 and the V-shaped slide groove 101 are clearance-matched, so that the moving trajectory of the pulley 11 can be presented as an arc in the slide groove 101.

[0029] In other technical solutions, the distribution track of the slide groove 101 can be a semicircular arc, and the outer edge surface of the pulley 11 can be close to the inner walls on both sides of the slide groove 101, so that the pulley 11 can slide completely along the distribution track of the slide groove 101.

[0030] Through holes are provided at both ends of the deflection member 16, and each through hole has an opening, so the through hole has a certain degree of elasticity. The rotating shaft of the pulley 11 and the rotating shaft 15 are respectively plugged into the two through holes, and the two ends of the rotating shaft 15 have a flat structure, and then the through holes are locked and locked by bolts, so as to fix the rotating shaft and the rotating shaft 15, and prevent the deflection member 16 from rotating with the rotating shaft and the rotating shaft 15.

[0031] In the same principle, a through hole is also provided on the flip connection member 3, and the other end of the rotating shaft 15 is locked and fixed to the flip connection member 3 in the same manner as described above.

[0032] like Figure 3 As shown, the clamping mechanism 4 is composed of a finger cylinder 41 and two clamping jaws 42. The two clamping jaws 42 are connected to the output end of the finger cylinder 41. The finger cylinder 41 can control the opening or closing of the two clamping jaws 42. The shapes of the opposite sides of the two clamping jaws 42 are adapted to the shape of the product, so that the product can be positioned.

[0033] refer to Figure 1 A mounting plate 6 is arranged above the fixed plate 2, and a lifting cylinder 7 is vertically arranged on the mounting plate 6. The output end of the lifting cylinder 7 is connected to the fixed plate 2. When the clamping mechanism 4 clamps the product on the fixture plate 9, the lifting cylinder 7 lifts the product to a certain height, and then the flipping drive mechanism 5 drives the flipping control plate 10 to move, and the pulley 11 cooperates with the slide groove 101 to drive the deflection member 16 to deflect, thereby driving the product to rotate along with the rotating shaft to flip the product.

[0034] The reason why the product needs to be raised to a certain height before flipping is to prevent the fixture under the product from interfering with the flipping of the product.

[0035] The track shape of the pulley 11 when sliding in the slide groove 101 is semicircular, so the flipping device can control the product to flip between 0-180°. When the pulley 11 slides to the positions of the two ends of the slide groove 101, it can stop sliding, which can ensure that the flipping angle of the product is 180° without worrying about the inaccurate flipping angle of the product, which will not affect the assembly of the product.

[0036] In other technical solutions, the pulley 11 may not be provided, and an insertion rod may be provided. The insertion rod is inserted into the slide groove 101 and moves along the track of the slide groove 101, which can also achieve the same function.

[0037] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
